DETAILED DESCRIPTION

[0016] It should be noted that, in the case of no conflict, embodiments in this disclosure and technical characteristics in the embodiments can be combined with each other, and the detailed description in the specific implementations should be understood as an explanation of the purpose of this disclosure, and should not be regarded as an improper limitation of this disclosure.

[0017] The present disclosure will be further described in detail with reference to the accompanying drawings and specific embodiments. Descriptions such as first and second in the embodiments of the present disclosure are for descriptive purposes only, and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature.

[0018] Some embodiments of the present disclosure provide a cleaning system, see FIGS. 1 to 4. The cleaning system 100 includes a base station 1, a vacuum cleaner 2, a primary lock 3 and an unlocking mechanism 4. A dust collection bin 1a is formed in the base station 1. The vacuum cleaner 2 includes a dust cup assembly, the dust cup assembly includes a dust cup 21 and a covering door 22, the dust cup 21 has a dust collection chamber 21a and a dust discharge opening 21b communicated with the dust collection chamber 21a, and the covering door 22 may selectively open or close the dust discharge opening 21b. The unlocking mechanism 4 includes a primary unlocking member 41 and a secondary lock 42, and the secondary lock 42 is disposed at the base station 1. In a state where the vacuum cleaner 2 is docked with the base station 1, the primary unlocking member 41 allows the primary lock 3 to unlock the covering door 22, and the secondary lock 42 can selectively lock or unlock the covering door 22.

[0019] In the cleaning system 100 provided in some embodiments of the present disclosure, the dust collection chamber 21a and the dust discharge opening 21b are formed in the dust cup 21, the covering door 22 can selectively open or close the dust discharge opening 21b, and the primary lock 3 can selectively lock or unlock the covering door 22. In this way, when the vacuum cleaner 2 operates on a surface to be cleaned, the first lock 3 can lock the covering door 22 to close the dust discharge opening 21b, so that foreign objects such as dust or garbage in the dust collection chamber 21a can be prevented from leaking out of the dust cup 21 through the dust discharge opening 21b. Since the dust collection bin 1a is formed in the base station 1, when the foreign objects in the dust collection chamber 21a needs to be cleared, the vacuum cleaner 2 is docked with the base station 1, and then the primary unlocking member 41 can cause the primary lock 3 to unlock the covering door 22, the primary lock 3 thus is in an unlocked state. In this way, when the user does not want to clean the dust collection chamber 21a or forgets to load a dust bag, the covering door 22 can be locked by the secondary lock 42, so as to prevent the covering door 22 from being opened by mistake. When the dust collection chamber 21a needs to be cleaned, the covering door 22 can be unlocked by operating the secondary lock 42 to open the dust discharge opening 21b. In this way, the opening of the covering door 22 can be made to meet the subjective wishes of the user, and the user's control on the vacuum cleaner 2 can be improved. After the primary unlocking member 41 allows the primary lock 3 to unlock the covering door 22 and the secondary lock 42 unlocks the covering door 22, the foreign objects in the dust collection chamber 21a can be collected in the dust collection bin 1a through the dust discharge opening 21b, so that the cleaning of the dust collection chamber 21a can be maintained, and a good foreign object and dust storage space can be provided for the next cleaning of the surface to be cleaned.

[0020] As an example, in some embodiments, in order to open the dust discharge opening 21b of the vacuum cleaner 2 in the base station 1, two unlocking operations are required. The first unlocking operation is to unlock the primary lock 3 by the primary unlocking member 41, so that the bondage between the covering door 22 and the dust cup 21 can be released, and the primary lock 3 thus is in an unlocked state. The second unlocking operation is to unlock the covering door 22 by the secondary lock 42. As such, the two unlocking operations are completed, and the dust discharge opening 21b is opened.

[0021] As an example, in some embodiments, the vacuum cleaner 2 may be hooked to outside of the base station 2.

[0022] In some embodiments, the primary unlocking member 41 may be provided on the base station 1.

[0023] As an example, in some embodiments, the primary unlocking member 41 may be provided in the dust collection bin 1a, so that the primary unlocking member 41 can be protected to a certain extent and its service life can be increased.

[0024] In other embodiments, the primary unlocking member 41 may also be provided on the vacuum cleaner 2.

[0025] It should be noted that the dust collection bin 1a described herein is a bin or chamber for accommodating the dust cup 21, and in particular, the dust collection bin 1a may be a dust collection air duct, or a dust debris collection part of the base station 1.

[0026] As an example, in some embodiments, the shape of the dust cup 21 is not limited, for example, it may be cylindrical, or conical, etc.

[0027] As an example, in some embodiments, the vacuum cleaner 2 may be, but is not limited to, a handheld vacuum cleaner 2. First, the handheld vacuum cleaner is small and light, and can be easily carried, thus avoiding the inflexibility and bulkiness of the vacuum cleaner 2 in the related art. Second, the handheld vacuum cleaner 2 has a wide applicability, which can clean various cleaning occasions such as floors, carpets, sofas and mattresses. Third, the handheld vacuum cleaner 2 is convenient to use, which does not need to drag a long dust suction pipe, a plug, etc.

[0028] In some embodiments, referring to FIGS. 1 to 3, the covering door 22 is rotatably connected to the dust cup 21. In this way, by rotating the covering door 22 about the rotation axis, the dust discharge opening 21b can be opened or closed.

[0029] As an example, in some embodiments, referring to FIGS. 1 to 3, the vacuum cleaner 2 includes a rotating shaft 23, a first rotating aperture formed on a side of the covering door 22 away from the primary lock 3, and a second rotating aperture formed on a side of the dust cup 21 away from the primary lock 3, the rotating shaft 23 passes through the first rotating aperture and the second rotating aperture. In this way, the covering door 22 can be rotated by the rotating shaft 23 and the rotating aperture. On the one hand, the number of components required for the rotation of the rotating shaft 23 and the rotating aperture is small, maintenance is easy and reliability is high; on the other hand, the rotation of the rotating shaft 23 and the rotating aperture does not need to use a complicated hydraulic and pneumatic system, has low maintenance cost, and is easy to be realized.

[0030] In some embodiments, referring to FIGS. 1 to 4, the primary lock 3 includes a first locking sub-element 31 and a second locking member, the first locking sub-element 31 being slidably disposed on an outer wall of the dust cup 21. For example, the first locking sub-element 31 may be provided on the outer wall on a side of the dust cup 21 away from the second rotating aperture. The second locking sub-element is provided on the covering door 22. As an example, the second locking sub-element may be provided on a side of the covering door 22 away from the first rotating aperture to avoid structural interference.

[0031] The first locking sub-element 31 and the second locking sub-element cooperate to selectively lock or unlock the covering door 22. In a state where the vacuum cleaner 2 is docked with the base station 1, the primary unlocking member 41 pushes the first locking sub-element 31 to slide, so that the first locking sub-element 31 is separated from the second locking sub-element. In this way, when it is necessary to clean the foreign objects in the dust collection chamber 21a, the vacuum cleaner 2 can be docked with the base station 1, and the primary unlocking member 41 in the dust collection bin 1a will contact the first locking sub-element 31 on the dust cup 21 to push the first locking sub-element 31 to slide, so that the first locking sub-element 31 and the second locking sub-element are separated from each other due to relative movement therebetween to complete the unlocking of the covering door 22 by the primary unlocking member 41. At this time, the primary lock 3 is in an unlocked state, so that the user subsequently can open or close the dust discharge opening 21b on his/her subjective wishes.

[0032] As an example, in some embodiments, a mounting groove may be provided in the covering door 22, and the second locking sub-element may be fixed in the mounting groove, so that a stable cooperating position may be provided for the first locking sub-element 31.

[0033] As an example, in some embodiments, the second locking sub-element is bonded to the covering door 22 by a viscous material such as glue, so that forming a groove in the covering door 22 can be avoided, thereby reducing damage to the covering door 22.

[0034] In some embodiments, the first locking sub-element 31 cooperates with the second locking sub-element in a magnetic attraction manner. In this way, the connection of both sub-elements can be realized through the magnetic attraction method without external force, which is convenient to use, simple and easy to operate, and has high stability.

[0035] In some embodiments, one of the first locking sub-element 31 and the second locking sub-element is a magnetic body, and the other one of the first locking sub-element 31 and the second locking sub-element is a material magnetically attracted to the magnetic body. As an example, the magnetic member may be a permanent magnet or an electromagnet, and the material magnetically attracted to the magnetic member may be a material such as iron, nickel, or chromium. For example, one of the first locking sub-element 31 and the second locking sub-element is a permanent magnet, and the other one of the first locking sub-element 31 and the second locking member is a ferromagnetic material such as iron, nickel, or chromium. Further, for example, one of the first locking sub-element 31 and the second locking sub-element 31 is an electromagnet, and the other one of the first locking sub-element 31 and the second locking sub-element is a material such as iron, nickel, or chromium.

[0036] In some embodiments, both the first locking sub-element 31 and the second locking sub-element 31 are magnetic bodies. For example, both the first locking sub-element 31 and the second locking sub-element may be permanent magnets. Further, for example, both the first locking sub-element 31 and the second locking sub-element may be electromagnets. Furthermore, for example, one of the first locking sub-element 31 and the second locking sub-element is an electromagnet, and the other one of the first locking sub-element 31 and the second locking sub-element is a permanent magnet.

[0037] In some embodiments, one of the first locking sub-element 31 and the second locking sub-element is a snap, the other one of the first locking sub-element 31 and the second locking sub-element is a slot, and the snap is snap-fitted into the slot. As an example, the first locking sub-element 31 may be a snap and the second locking sub-element may be a slot, in this way, on the one hand, the connection mode between the snap and the slot has strong connection strength and stability, so that the covering door 22 is not easily disengaged when the vacuum cleaner 2 is in operation; on the other hand, the snap-fit mode makes the connection and disconnection between the dust cup 21 and the covering door 22 relatively simple. In other embodiments, the first locking sub-element 31 may be a slot and the second locking sub-element may be a snap.

[0038] In some embodiments, referring to FIGS. 1 and 2, an entry and exit opening 1b is formed on an upper surface of the dust collection bin 1a, the dust discharge opening 21b is formed on a lower surface of the dust cup 21, and the covering door 22 enters and exits the dust collection bin 1a in an up-down direction through the entry and exit opening 1b. In this way, when it is necessary to clear the foreign objects in the dust collection chamber 21a, the covering door 22 can be inserted into the dust collection bin 1a through the entry and exit opening 1b in the up-down direction. On the one hand, the vacuum cleaner 2 is inserted into the base station 1 in the up-down direction, which can reduce the footprint of the cleaning system 100, and further facilitate insertion or removal operations made by the user. On the other hand, since the entry and exit opening 1b is formed on the upper surface of the dust collection bin 1a and the dust discharge opening 21b is formed on the lower surface of the dust cup 21, the foreign objects in the dust collection chamber 21a can fall into the dust collection bin 1a by their own gravities, the cleaning thus is relatively simple. Furthermore, after the secondary lock 42 unlocks the covering door 22, the covering door 22 can rotate about the rotating shaft 23 by its own gravity, so as to open the dust discharge opening 21b.

[0039] In some embodiments, referring to FIGS. 1 to 4, the vacuum cleaner 2 includes a housing 24 connected to an outer peripheral surface of the dust cup 21, and the housing 24 and the outer peripheral surface of the dust cup 21 together define an accommodating chamber 24a. As an example, the housing 24 may be provided on a side of the dust cup 21 away from the second rotating aperture; the shape of the housing 24 is not limited, for example, the housing 24 may be a hollow cylindrical housing so that the accommodating chamber 24a is substantially cylindrical. The accommodating chamber 24a is provided with a communication opening 24b facing the covering door 22. That is, the bottom of the accommodating chamber 24a is provided with an opening. In a state where the vacuum cleaner 2 is docked with the base station 1, the accommodating chamber 24a can be communicated with the dust collection bin 1a through the communication opening 24b.

[0040] An extending opening 24c communicating with the accommodating chamber 24a is provided on a circumferential side of the housing 24, and a portion of the first locking sub-element 31 is provided in the accommodating chamber 24a. In this way, on the one hand, the first locking sub-element 31 can be protected to a certain extent, so as to increase the service life of the first locking sub-element 31; on the other hand, a portion of the first locking sub-element 31 is provided in the accommodating chamber 24a, so that in a state where the vacuum cleaner 2 is docked with the base station 1, when the first locking sub-element 31 is pushed by the primary unlocking member 41 to slide, the accommodating chamber 24a can play a certain guiding role on the first locking sub-element 31 and provide a movement space for the first locking sub-element 31, thereby avoiding the situation that the first locking sub-element 31 and the second locking sub-element cannot be separated, and the working stability is good.

[0041] The first locking sub-element 31 cooperates with the second locking sub-element through the communication opening 24b. For example, in a state where the covering door 22 is pulled out of the dust collection bin 1a upwardly, the first locking sub-element 31 slides downwards, for example, under the action of the elastic member 32, so that a portion of the first locking sub-element 31 slides to the vicinity of the communication opening 24b. At this time, the covering door 22 is rotated about the rotating shaft 23 towards a direction approaching the first locking sub-element 31 to close the dust discharge opening 21b, and the second locking sub-element on the covering door 22 is cooperatively connected with the first locking sub-element 31 to lock the covering door 22.

[0042] The portion of the first locking sub-element 31 passing through the extending opening 24c is configured to contact the primary unlocking member 41. For example, taking the vacuum cleaner 2 inserted downwards into the dust collection bin 1a as an example, in a state where the vacuum cleaner 2 is docked with the base station 1, the portion of the first locking sub-element 31 passing through the extending opening 24c is contacted and pushed by the primary unlocking member 41, thereby driving the portion of the first locking sub-element 31 located in the accommodating chamber 24a to slide upwards, causing the portion of the first locking sub-element 31 located at the communication opening 24b to enter the accommodating chamber 24a, so that the first locking sub-element 31 is separated from the second locking sub-element, the covering door 22 is then unlocked, and the dust discharge opening 21b is in a state to be opened.

[0043] As an example, in some embodiments, the entire primary unlocking member 41 may be located in the dust collection bin 1a, for example, the primary unlocking member 41 may be a stopper, one end of the primary unlocking member 41 is fixed on a wall of the dust collection bin 1a, and another end of the primary unlocking member 41 extends towards a direction approaching the dust cup 21. Taking the vacuum cleaner 2 inserted into the dust collection bin 1a as an example, the portion of the first unlocking sub-element 31 passing through the extending opening 24c will contact an extension part of the primary unlocking member 41 to prevent the first unlocking sub-element 31 from continuing to move downwards, so that there is a relative movement between the first unlocking sub-element 31 and the covering door 22, causing the portion of the first unlocking sub-element 31 located at the communication opening 24b to be separated from the second unlocking sub-element, and thus the covering door 22 is unlocked. In this way, the appearance of the base station 1 can be clean and tidy by placing the entire first locking sub-element 31 in the dust collection bin 1a.

[0044] In some embodiments, a portion of the primary unlocking member 41 may be located within the dust collection bin 1a and another portion of the primary unlocking member 41 may extend to outside the dust collection bin 1a, and the portion of the primary unlocking member 41 located within the dust collection bin 1a can contact with the first locking sub-element 31.

[0045] As an example, in some embodiments, the accommodating chamber 24a is separated from the dust collection chamber 21a, that is, foreign objects in the dust collection chamber 21a cannot enter into the accommodating chamber 24a, thereby preventing the foreign objects from leaking out of the vacuum cleaner 2 through the communication opening 24b and the extending opening 24c thereon, and thus the sealing effect of the dust collection chamber 21a is good.

[0046] In some embodiments, referring to FIGS. 1 to 4, the primary lock 3 includes an elastic member 32 connected to the first locking sub-element 31. As an example, the elastic member 32 may be provided in the accommodating chamber 24a, for example, one end of the elastic member 32 is connected to a top wall of the accommodating chamber 24a, and another end of the elastic member 32 is connected to a side of the first locking sub-element 31 away from the communication opening 24b, so that the elastic member 32 can perform compression and elongation by taking the top wall of the accommodating chamber 24a as a support point, thereby driving the first locking sub-element 31 to slide.

[0047] In a state where the vacuum cleaner 2 is docked with the base station 1, the primary unlocking member 41 pushes the first locking sub-element 31 to drive the elastic member 32 to undergo elastic deformation. For example, taking the vacuum cleaner 2 inserted downwardly into the dust bin 1a as an example, in a state where the vacuum cleaner 2 is docked with the base station 1, a portion of the first locking sub-element 31 passing through the extending opening 24c contacts the extension portion of the primary unlocking member 41 to prevent the first locking sub-element 31 from continuing to move downwards. In this way, the first locking sub-element 31 presses the elastic member 32 upwardly, so that the portion of the first locking sub-element 31 located at the communication opening 24b is separated from the second locking sub-element, and the covering door 22 is unlocked. In this way, by providing the elastic member 32, a certain pre-tightening force can be provided to reduce the accidental unlocking of the covering door 22 and improve the reliability of unlocking the covering door 22. In a state where the covering door 22 is removed from the dust collection bin 1a, the elastic member 32 resumes elastic deformation to reset the first locking sub-element 31. For example, taking vacuum cleaner 2 inserted downwards into dust collection bin 1a as an example, after the foreign objects in the dust collection chamber 21a are discharged into the dust collection bin 1a, and during the vacuum cleaner 2 is pulled upwardly out of the dust collection bin 1a, the elastic member 32 resumes elastic deformation, thereby pushing the first locking sub-element 31 downwardly, so that the portion of the first locking sub-element 31 away from the elastic member 32 automatically approaches the communication opening 24b. In this way, when the covering door 22 is rotated about the rotating shaft 23 towards the direction approaching the first locking sub-element 31, the portion of the first locking sub-element 31 close to the communication opening 24b will be fit and connected with the second locking sub-element, and the covering door 22 is locked.

[0048] As an example, in some embodiments, the elastic member 32 may be a spring, so that springs made of different materials can be selected according to different requirements to provide different pretension forces, which has a high selectivity and a low manufacturing cost.

[0049] In some embodiments, referring to FIGS. 1 and 2, the secondary lock 42 can lock the lower surface of the covering door 22 or unlock the covering door 22 in a state where the vacuum cleaner 2 is docked with the base station 1. For example, the shape of the secondary lock 42 is not limited, for example, it may be a square, rectangular or triangular block. The base station 1 is formed with a cutout, which is communicated with the dust collection bin 1a, and in which the secondary lock 42 is movably arranged. Taking the vacuum cleaner 2 inserted downwardly into the dust collection bin 1a as an example, in the state where the vacuum cleaner 2 is docked with the base station 1, a portion of the secondary lock 42 located in the dust collection bin 1a through the cutout abuts against the lower surface of the covering door 22, resulting in the covering door 22 being unable to rotate about the rotating shaft 23 towards a direction away from the first locking sub-element 31, that is, the covering door 22 at this time cannot be opened due to being locked by the secondary lock 42. The secondary lock 42 is moved so that the secondary lock 42 is away from the covering door 22, and the secondary lock 42 cannot continue to abut against the covering door 22 to allow unlocking of the covering door 22. At this time, the covering door 22 can be rotated about the rotating shaft 23 towards a direction away from the first locking sub-element 31 to open the covering door 22, and then the foreign objects in the dust collection chamber 21a can enter the dust collection bin 1a through the dust discharge opening 21b, so as to complete the removal of the foreign objects in the dust collection chamber 21a, and provide a good storage space for the next cleaning of the surface to be cleaned.

[0050] As an example, in some embodiments, referring to FIGS. 1 and 2, the secondary lock 42 abuts against the lower surface of the covering door 22 or dodges the covering door 22 in a push-pull manner in the horizontal direction. For example, when the covering door 22 needs to be locked, the secondary lock 42 can be pushed into the dust collection bin 1a through the cutout, so that in the state where the vacuum cleaner 2 is docked with the base station 1, the lower surface of the covering door 22 can be abutted against the secondary lock 42 to lock the covering door 22. When it is necessary to dodge the covering door 22 to open the dust discharge opening 21b, the secondary lock 42 can be pulled out of the dust collection bin 1a through the cutout, so that there is no obstruction below the covering door 22, and the covering door 22 then can be rotated about the rotating shaft 23 towards a direction away from the first locking sub-element 31, thereby opening the dust discharge opening 21b. As an example, in some embodiments, the secondary lock 42 can also be pressed in an up-down direction to lock the lower surface of the covering door 22 or unlock the covering door 22. Since the rotation track of the covering door 22 about the rotating shaft 23 at the second locking sub-element is circular, when it is necessary to dodge the covering door 22 to open the dust discharge opening 21b, the secondary lock 42 can be pressed downward to move it away from the rotation track of the covering door 22. In this way, the covering door 22 can be dodged.

[0051] As an example, in some embodiments, the unlocking mechanism 4 includes an elastomer which may be provided on the right side of the secondary lock 42 and which may automatically keep the secondary lock 42 in a locked state; when it is necessary to unlock, the secondary lock 42 can be pulled out of the dust collection bin 1a by an external force. At this time, the covering door 22 falls, and after the corresponding operation is stopped, the secondary lock 42 automatically moves into the dust collection bin 1a.

[0052] In some embodiments, referring to FIGS. 1 and 2, the primary unlocking member 41 is located above the secondary lock 42. In this way, in the state where the vacuum cleaner 2 is docked with the base station 1, the primary unlocking member 41 first causes the primary lock 3 to automatically unlock the covering door 22, and the primary lock 3 is in the unlocked state, and then the user can operate the secondary lock 42 to lock the covering door 22 or unlock the covering door 22 by judging whether or not it is necessary to remove the foreign objects in the dust collection chamber 21a, thereby improving the user's control of the vacuum cleaner 2.

[0053] In some embodiments, the cleaning system 100 includes an electric motor provided on the base station 1 and configured to suck the gas of the dust collection bin 1a. The secondary lock 42 is operated and the electric motor is started in a state where the vacuum cleaner 2 is docked with the base station 1. For example, the electric motor may be a suction electric motor, and the electric motor may be arranged on the base station 1, and may be communicated with the dust collection bin 1a through a pipe to suck the gas in the dust collection bin 1a, so that the dust collection bin is in a negative pressure state. In this way, in a state that the vacuum cleaner 2 is docked with the base station 1, the primary unlocking member 41 causes the primary lock 3 to automatically unlock the covering door 22, then the secondary lock 42 is operated to unlock the covering door 22, the covering door 22 is finally automatically opened by the pressure difference between the dust collection chamber 21a and the dust collection bin 1a, so that the dust collection chamber 21a is in communication with the dust collection bin 1a. In this way, foreign objects in the dust collection chamber 21a can be removed relatively quickly and cleanly.

[0054] As an example, in some embodiments, the cleaning system 100 includes a torsion spring, the torsion spring is sleeved on the rotating shaft 23, the electric motor is started, the covering door 22 is opened, and the torsion spring stores potential energy with the rotation of the rotating shaft 2. After removing the foreign objects in the dust collection chamber 21a, the electric motor is turned off, and the torsion spring releases potential energy, so that the covering door 22 rotates towards a direction approaching the dust cup 21, to close the dust discharge opening 21b.

[0055] For those skilled in the art, the present disclosure may be subject to various modifications and variations. All modifications, equivalent replacements, improvements, etc. within the spirit and principles of this disclosure are included in the scope of protection of this disclosure.
