DETAILED DESCRIPTION OF THE INVENTION

[0039] In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments and the aspects thereof are described in detail herein, and the description is intended to be illustrative of the structure or the procedure steps of the present invention, which are provided for explanation and not used to limit the scope of claims of the present invention.

[0040] An embodiment described in the specification refers to particular features, methods or characteristics described in connection with this embodiment, which are included in at least some embodiments. Therefore, the implementation of various aspects of one embodiment or various embodiments is not necessarily the same embodiment. Furthermore, the features, methods, or characteristics of the present invention can be combined as appropriate in one or more embodiments.

[0041] Referring to FIG. 1 and FIG. 2, the present invention provides a vibration box on a negative pressure cup capable of strengthening airtightness for achieving waterproof, anti-collision and noise reduction functions, comprising a negative pressure cup 200 for providing a negative pressure health care function, and a vibration box 100 installed on the negative pressure cup 200 for providing a vibration function.

[0042] The vibration box 100 has an accommodation space 110 therein for disposing a vibration motor 400. A back of the vibration box 100 is disposed with a vibration box back cover 120, so that the vibration box back cover 120 covers the back of the vibration box 100 to seal the accommodation space 110.

[0043] Referring to FIG. 1 to FIG. 4 and FIG. 4A, the present invention mainly provides a waterproof rubber element 300 which is newly applied to prevent water from penetrating into the vibration box 100, and is applied to the waterproof design required for the vibration box 100. In one embodiment, the waterproof rubber element 300 is disposed on the vibration box back cover 120 and a contact surface of the vibration box 100. A surface of the waterproof rubber element 300 is disposed with recesses 310 with a concave cross section, and a shape of the recess 310 is, for example, a U shape or an inverse U shape. In one embodiment, the waterproof rubber element 300 can be molded.

[0044] In one embodiment, the waterproof rubber element 300 can be made of synthetic rubbers (also known as thermosetting polymers) such as but not limited to, butadiene rubber (BR), isobutylene isoprene rubber (IIR), chlorosulfonated polyethylene rubber (CSM, complete supplement mixture), ethylene propylene diene monomer (EPDM), ethylene-propylene rubber (EPR), fluororubber (FKM, fluorocarbon), nitrile butadiene rubber (NBR), perfluoroelastomer (FFKM), polyacrylate rubber (ACR), chloroprene rubber (CR), polyisoprene rubber (IR), polysulfide rubber (PSR), silicone rubber (SIR), styrene butadiene rubber (SBR); or thermoplastics such as but not limited to, thermoplastic elastomers (TPE) (e.g. styrene), thermoplastic polyolefin (TPO) (e.g. LDPE low density polyethylene, HDPE high density polyethylene, LLDPE linear low density polyethylene, ULDPE ultra low density polyethylene), thermoplastic polyurethane (TPU) (e.g. polyether, polyester), thermoplastic polyester/polyether elastomers (TEEE), thermoplastic polyamide (TPA) (e.g. polyamide), melt processable rubber (MPR), thermoplastic vulcanizate (TPV).

[0045] The U-shaped or inverse U-shaped recess 310 of the waterproof rubber element 300 can be sleeved on a flange 130 of the vibration box back cover 120, so that a size and a shape of the U-shaped or inverse U-shaped recess 310 of the waterproof rubber element 300 need to match with a size and a shape of the flange 130 of the vibration box back cover 120. The waterproof rubber element 300 that is sleeved on the flange 130 can be further disposed in a groove 140 provided on the vibration box 100 and the contact surface of the vibration box back cover 120, so that an outer side surface of the waterproof rubber element 300 is in close contact with the groove 140, and the recess 310 is sleeved on the flange 130 and embedded in the groove 140 to be completely sealed, thereby achieving a waterproof effect. The U-shaped or inverse U-shaped recess 310 of the waterproof rubber element 300 can be sleeved on the flange 130, so that it is easier to install, not easy to displace, and not easy to fall off in installation, and is not susceptible to variations in the assembly method, otherwise will reduce or lose the waterproof effect.

[0046] Further, the waterproof rubber element 300 is a malleable elastic body made of the foregoing materials, and when the waterproof rubber element 300 is sandwiched between the vibration box back cover 120 and the vibration box 100, the waterproof rubber element 300 is forcefully expanded to completely fit on the flanges 130 and the grooves 140.

[0047] The flange 130 of the vibration box back cover 120 and the groove 140 of the vibration box 100 are designed to be interchangeably disposed. Of course, a direction of the recess 310 of the waterproof rubber element 300 is adjusted to match with positions of the flange 130 and the groove 140.

[0048] In one embodiment, the waterproof rubber element 300 is integrally formed by a strip surrounding the vibration box back cover 120 and the contact surface of the vibration box 100, with appearance like a mesh structure. Alternatively, the waterproof rubber element 300 can be disposed as a monolithic panel structure (not shown in the figures) that is capable of completely covering the back of the vibration box 100, and the recess 310 is disposed only at a position where the panel-like waterproof rubber element 300 contacts the contact surface, so that the panel-like waterproof rubber element 300 completely covers and seals the accommodation space 110 of the vibration box 100.

[0049] Another focus of the present invention is to provide a noise reduction cover 410 and a buffer cushion 420 for the anti-collision and noise reduction functions of the vibration box 100. Please refer to FIG. 1, FIG. 2, FIG. 5 and FIG. 5A. In one embodiment, the noise reduction cover 410 is hooded outside the vibration motor 400, and the vibration motor 400 is fixed on the vibration box 100 by the noise reduction cover 410 to securely fix a position of the vibration motor 400. Therefore, the vibration motor 400 can be stably operated in the vibration box 100 without arbitrary sway, otherwise will cause the vibration motor 400 to impact on the vibration box 100, and further, due to the cover of the noise reduction cover 410, noise generated by the vibration motor 400 is further reduced.

[0050] The noise reduction cover 410 has a same outer shape as that of an outer casing of the vibration motor 400 to securely fix the noise reduction cover 410 outside the vibration motor 400, thereby reducing the gap and effectively preventing noise from being transmitted.

[0051] In one embodiment, the buffer cushion 420 is disposed between the vibration motor 400 and the noise reduction cover 410 to ease off the sway of the vibration motor 400 itself.

[0052] The material for the soft cushioning of the buffer cushion 420 is mainly foam, but is not limited thereto, so as to surely exert the function of easing off the sway of the vibration motor 400.

[0053] In summary, the waterproof rubber element 300 of the present invention has a special shape that matches a size and a shape of the groove 140 of the waterproof structure of the vibration box 100, thereby achieving the technical efficacies of being relatively more secure, easier to install, not easy to displace, and not easy to fall off in installation, and not susceptible to variations in the assembly method, otherwise will reduce or lose the waterproof effect. The noise reduction cover 410 and the buffer cushion 420 further strengthen the fixing of the vibration motor 400, so that it is not easy to sway during operation, reducing the possibility of the vibration motor 400 colliding with the vibration box 100, and maintaining the durability of the product and reducing the occurrence of noise.

[0054] While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
