(15) Some embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. The features in the following embodiments may be combined with each other without conflict.

(16) Referring to FIGS. 1 to 8, the present disclosure proposes a manual sticker dispenser 100 for peeling a sticker on a sticker roll 8. The sticker is peelably affixed to a liner paper 81 and wound into the sticker roll 8. The manual sticker dispenser 100 is constructed to be capable of peeling the sticker from the liner paper 81 during a sticker conveying process and outputting the sticker from an output port 101.

(17) Referring to FIG. 3, the manual sticker dispenser 100 includes a housing 1, the housing 1 defining a second chamber 110 for accommodating the sticker roll 8; a conveying path 112 is defined in the second chamber 110, and the housing 1 defines the output port 101 in communication with the second chamber 110. A peeling structure 1121 is arranged on the conveying path 112, the peeling structure 1121 being disposed at the output port 101. The peeling structure 1121 is configured to peel the sticker from the liner paper 81 by conveying the liner paper 81 in a direction different from a travel direction of the sticker. Specifically, the peeling structure 1121 includes a turning peeling portion. The liner paper 81 extends in a relatively flat attitude towards the output port 101 when the liner paper 81 is disposed upstream of the turning peeling portion, and the liner paper 81 is bent backwards at the turning peeling portion to travel in a direction different from the travel direction of the sticker, causing the sticker to be peeled off of the liner paper 81. The liner paper 81 after reverse bending at the turning peeling portion is wound on a winding shaft 111. When the winding shaft 11 is driven to rotate, the winding shaft 11 pulls the liner paper 81 and the sticker affixed to the liner paper 81 to travel on the conveying path 112, and the sticker is peeled off through the peeling structure 1121.

(18) Referring to FIGS. 3 and 4, the manual sticker dispenser 100 includes the winding shaft 111, a transmission mechanism, and an operating member 2. The operating member 2 is connected to the transmission mechanism, and the transmission mechanism is power-transferably connected to the winding shaft 111. The operating member 2 is configured to operatively reciprocate within a set range; specifically, the operating member 2 is configured to be driven by an operating force to move in a first direction to move from a first position to a second position, as well as to move in a second direction opposite to the first direction to reset from the second position to the first position when the operating force is released. During the movement of the operating member 2 from the first position to the second position, a continuous power transmission chain is formed between the operating member 2, the transmission mechanism, and the winding shaft 111 to drive the winding shaft 111 in a positive rotation to wind the liner paper 81. During the resetting of the operating member from the second position to the first position, the power transmission chain is disconnected at least in one place between the operating member 28, the transmission mechanism, and the winding shaft 111, in order to avoid driving the winding shaft 111 in reverse.

(19) Referring to FIGS. 3 and 4, in the embodiments, the housing 1 includes a main body shell 11, an upper cover 12 disposed at a top of the main body shell 11, and a lower cover 13 disposed at a bottom of the main body shell 11; the main body shell 11 includes a bottom wall and a peripheral wall disposed at an edge of the bottom wall, where upper and lower edges of the peripheral wall extend beyond the bottom wall to define a second chamber 110 above the bottom wall for accommodating the sticker roll 8, and to define a first chamber 115 below the bottom wall for arranging the operating member 2 and the transmission mechanism. An end of the upper cover 12 is arranged with an elastic buckle 121 to detachably connect the upper cover 12 to the main body shell 11 for an easy replacement of the sticker roll 8. The lower cover 13 is fixed to the main body shell 11 by screw locking to prevent the transmission mechanism arranged in the first chamber 115 from falling out caused by the user easily opening the lower cover 13.

(20) Referring to FIGS. 4 to 6, in the embodiments, the operating member 2 is a pressable component, specifically a lever mechanism, configured to pivot around a set axis. The operating member 2 is pivotally connected to the housing 1, which includes a pressing portion 21 and a rack portion 22. The pressing portion 21 is exposed to the housing 1 and can be pressed by the user. The operating member 2 is in the first position before being pressed and is movable to the second position after being pressed. When the pressing portion 21 is pressed, the operating member 2 rotates about its pivot shaft, moving the rack portion 22. The operating member 2 is a one-piece part, e.g. plastic injection molded, and the rack portion 22 has multiple teeth integrally molded for use in conjunction with the transmission mechanism for transmitting power. In the embodiments, the rack portion 22 is curved and an axis of the curved shape is an axis of the pivot shaft of the operating member 2. The operating member 2 is resiliently pressed against the rack portion 22 by a reset spring 23, and the reset spring 23 provides a resilient force in the opposite direction to that of the pressing force. When the pressing force applied to the pressing portion is withdrawn, the reset spring 23 pushes the operating member 2 to rotate and reset to the first position prior to the application of the pressing force.

(21) Further referring to FIGS. 4-6, the transmission mechanism is a gear train transmission mechanism including multiple gears coupled to each other, which is configured to connect the operating member 2 and the winding shaft 111 in a transmission, and to transmit the power output from the operating member 2 to the winding shaft 111 in order to drive the winding shaft 111 to rotate. The transmission mechanism includes a one-way clutching device, which is configured to be coupled when the operating member 2 is moved in the first direction to implement the power transmission, and to be uncoupled when the operating member 2 is moved in the second direction opposite to the first direction to disconnect the power transmission. In the embodiments, the transmission mechanism includes a driven gear 5 fixed relative to the winding shaft 111, an actuating gear 3 driven in engagement with the rack portion 22 of the operating member 2, and a movable gear 4 disposed between the driven gear 5 and the actuating gear 3. Specifically, the transmission mechanism includes the actuating gear 3 located upstream of and remaining coupled to the movable gear 4 in the power transmission direction, and the driven gear 5 located downstream of and detachably coupled to the movable gear 4 in the power transmission direction.

(22) A gear shaft of the actuating gear 3 is non-translatably connected to the housing 1, and the actuating gear 3 is only capable of rotating about the axis of its gear shaft and is not movable in its axial and radial directions. In the embodiments, the actuating gear 3 is a double-layered tower gear having a small-diameter toothed disk 31 and a large-diameter toothed disk 32 that are arranged coaxial, the small-diameter toothed disk 31 of the actuating gear 3 being engaged with the rack portion 22 of the operating member 2, and the large-diameter toothed disk 32 of the actuating gear 3 being engaged with the movable gear 4. In other embodiments, the large-diameter toothed disk 32 may be understood as an actuating gear, and the small-diameter toothed disk 31 as a first gear further included in the transmission mechanism and coupled to the rack portion 2, the first gear and the actuating gear being coaxially disposed. The diameter D of the actuating gear is greater than double the diameter d of the first gear.

(23) The movable gear 4 is configured to be movable between a coupled position and a detached position, i.e. a gear shaft of the movable gear 4 is translationally connected to the housing 1, while the movable gear 4 is also rotatable about an axis of its gear shaft. An end of the gear shaft of the movable gear 4 is connected to a bottom wall of the main body shell 11 and the other end of the gear shaft of the movable gear 4 is connected to the lower cover 13. Specifically, the bottom wall of the main body shell 11 defines an upper elongate slot 113 configured for an upper end of the gear shaft of the movable gear 4 to be inserted and slide therein; the lower cover 13 defines a lower elongate slot 131 configured for a lower end of the gear shaft of the movable gear 4 to be inserted and slide therein. The upper elongate slot 113 and the lower elongate slot 131 are opposite each other in the top-bottom direction, forming guide slots for the rotation shaft of the movable gear 4 to be inserted into and to slide within. When the rack portion 22 of the operating member 2 is engaged with the movable gear 4, the movable gear 4 can be pushed to slide along the guiding slot 131. When the movable gear 4 slides to the coupled position, it can engage with the driven gear 5. When the movable gear 4 slides to the detached position, it can disengage with the driven gear 5.

(24) In the embodiments, the one-way clutching device includes the movable gear 4 and a force-applying member 6. The movable gear 4 is resiliently pushed against by the force-applying member 6, and the force-applying member 6 is configured to apply a resilient force to hold the movable gear 4 in the coupled position. When the operating member 2 moves in the second direction from the second position to the first position, the operating member 2 drives the movable gear 4 to overcome the resilient force and to slip to the detached position. The force-applying member 6 may be a torsion spring or a resilient sheet, with a resilient arm that abuts against the movable gear 4 to exert the resilient force. In the embodiments, the force-applying member 6 is a torsion spring having two resilient arms, one of which abuts against the movable gear 4 and the other abuts against the housing 1. In the embodiments, the spring force of the force-applying member 6 is overcome to separate the movable gear 4 from the driven gear 5. In other embodiments, the force-applying member 6 is configured to apply a resilient force for the movable gear 4 to remain in the detached position, and the operating member 2 drives the movable gear 4 to overcome the resilient force to slide to the coupled position when the operating member 2 moves in the first direction from the first position to the second position; herein when the operating force is released, the movable gear 4 is separated under the action of the spring force of the force-applying member 6. For the embodiments, the force-applying member 6 instantly drives the movable gear 4 to the detached position from the driven gear 5 when the external force on the operating member 2 is removed, such that the separation is timelier and the driven gear 5 can be better avoided from being driven to rotate in reverse. Further, there exists a small slip distance for the movable gear 4 to move from the detached position to the coupled position during the movement of the operating member 2 in the first direction, and the driven gear 5 is not driven in the slip distance, i.e. there exists a small empty travel distance of the operating member 2. In the embodiments, the reset spring 23 provides a resilient resetting force greater than the resilient force applied to the movable gear 4 by the force-applying member 6.

(25) In the embodiments, the movable gear 4 is a double-layered tower gear having a small-diameter toothed disk 41 and a large-diameter toothed disk 42 that are arranged coaxial, the small-diameter toothed disk 41 of the movable gear 4 being engaged with the actuating gear 5, and the large-diameter toothed disk 42 of the movable gear 4 being engaged with the large-diameter toothed disk 32 of the actuating gear 3. The provision of the actuating gear 3 and movable gear 4 may serve to amplify the fact that the rotation angle of the actuating gear 3 is less than the rotation angle of the driven gear 5 during the movement of the operating member 2 from the first position to the second position.

(26) The driven gear 5 is coaxially and relatively fixedly connected to the winding shaft 111. In the embodiments, the driven gear 5 is connected to the winding shaft 111 by a coupling structure. Specifically, a gear shaft of the driven gear 5 is arranged with a polygonal post, and a lower end of the winding shaft 111 is arranged with a polygonal sleeve, the polygonal post being inserted into the polygonal sleeve to realize a relative fixation of the polygonal post and the polygonal sleeve in a rotation direction.

(27) Focusing on FIG. 7, which is a schematic diagram of an action of the transmission mechanism during the movement of the operating member 2 in the first direction driven by an operating force: a force is applied to the pressing portion of the operating member 2 as shown by the arrow above thereof, the rack portion 22 of the operating member 2 rotates inwardly as shown by the arrow above thereof, and the actuating gear 3 rotates clockwise as shown by the arrow, in which case the movable gear 4 is pushed to translate in a direction close to the driven gear 5 and engage with the driven gear 5, and the driven gear 5 clockwise rotates as shown by the arrow, driving the winding shaft 111 to rotate in order to pull the liner paper 81 to move, thereby realizing the peeling off of the sticker and the output of the sticker.

(28) Focusing on FIG. 8, which is a schematic diagram of an action of the transmission mechanism during a process in which the operating force applied to the operating member 2 is released and the operating member 2 is driven by the reset spring 23 to move in the second direction to reset to the first position: a force is applied to the rack portion 22 of the operating member 2 as shown by the arrow above thereof, the pressing portion of the operating member 2 moves outward as shown by the arrow above thereof, and the actuating gear 3 rotates counterclockwise as shown by the arrow, in which case the movable gear 4 is pushed to translate in a direction away from the driven gear 5 and disengage with the driven gear 5, and the rotation of the movable gear 4 driven by the actuating gear 3 is unable to be transmitted to the driven gear 5, i.e., the driven gear 5 does not rotate counterclockwise, and the winding shaft 111 does not move, thereby avoiding that the wound liner paper is loosened and the sticker cannot be output when the operating member is pressed next time, caused by the winding shaft 111 rotating counterclockwise in the course of resetting the operating member 2.

(29) It should be noted that the present embodiments are illustrated with the movable gear 4 and the driven gear 5 being able to be disengaged as an example, and it can be understood that in other embodiments, it is sufficient to arrange such that a disengagement is feasible at any position in the transmission chain between the operating member 2 and the winding shaft 111. It should also be noted that, in the present embodiments, the switching between engagement and disengagement is achieved by translation of the movable gear 4, which in other embodiments can be achieved by means of a ratchet structure. For example, in some embodiments, the one-way clutching device is a one-way bearing, i.e. an overrunning clutch, which is coupled to a transmission gear within the transmission mechanism; the one-way bearing is free to rotate in one direction independently of the winding shaft 111, while in the other direction opposite, the one-way bearing is locked to the winding shaft 111 and both rotate in synchronization.

(30) As can be seen from the above description of specific embodiments, the present disclosure provides a manual sticker dispenser 100 including a winding shaft 111, a transmission mechanism, and an operating member 2; the operating member 2 is configured to be driven by an operating force to move in a first direction, and is configured to move in a second direction opposite to the first direction when the operating force is released; during a movement of the operating member 2, a continuous power transmission chain is formed between the operating member 2, the transmission mechanism, and the winding shaft 111, to drive the winding shaft 111 to rotate and wind the liner paper; during a movement of the operating member 2 in the second direction, the one-way clutching device disconnects the power transmission, which avoids driving the winding shaft 111 in reverse. Therefore, the output of stickers may be realized by manually applying force on the operating member 2, without using electrical components, thereby reducing costs and enhancing operability and entertainment.

(31) Although the above description has been made herein with reference to specific embodiments, the scope of the present disclosure is not limited thereto. The preceding detailed description is intended to be considered illustrative and not limiting, and it should be understood that the appended claims, including all equivalents, are intended to limit the scope of the present disclosure. The claims should not be construed to be limited to the order or elements described, except as indicated. Accordingly, all embodiments falling within the scope and spirit of the appended claims and their equivalents are claimed to be protected by the present disclosure.
