AI Technical Summary
During the use of existing physiotherapy instruments, the internal components generate a large amount of heat and need to be dissipated in time. However, the conventional heat dissipation hole structure can easily cause water inlet in the shell and damage the components. Especially the portable physiotherapy instruments have more heat dissipation and waterproofing. A big challenge.
A waterproof and heat dissipation shell is designed, including a heat dissipation hole and a frame on the back of the lower case. A heat dissipation fin is installed on the inner side. The heat dissipation fin cover is installed on the frame and fixed by waterproof glue to form a sealing structure. The heat dissipation hole is gridded. The grating shape is to enhance aesthetics and waterproof effect. The charging port and pin socket are equipped with waterproof plugs and pads. When the shell is assembled, the heat sink is a copper sheet and is bent to fit the inner wall of the shell to ensure space.
It realizes effective heat dissipation of components and waterproofing of the shell, ensures the safety of internal components, and avoids water entering the shell, which not only improves the heat dissipation effect but also enhances the sealing.

Abstract
Description
Technical Field
[0001] The utility model relates to a shell, in particular to a waterproof heat dissipation shell. Background Art
[0002] As people pay more and more attention to health, when people feel uncomfortable, most of them will choose physical therapy devices for physical therapy or massage to relieve muscle or nerve pain. Conventional physical therapy devices are generally divided into low-frequency physical therapy devices, medium-frequency physical therapy devices and high-frequency physical therapy devices according to the level of their output pulses and the number of functions. Users choose physical therapy devices according to their needs. The higher the frequency of the physical therapy device, the larger its overall structure. However, the current technical trend is to reduce the size of medium and high-frequency physical therapy devices to facilitate users to carry and use.
[0003] The existing physiotherapy devices generally have two types: handheld and desktop. Desktop physiotherapy devices are larger in overall structure and have more functions; handheld physiotherapy devices are smaller in structure and more convenient for users to carry. However, during the use of the physiotherapy device, the internal components generate a lot of heat and need to be dissipated in time. The use of conventional heat dissipation hole structures can easily cause water to enter the shell and damage the components. Especially for portable physiotherapy devices, due to their smaller overall structure, there are more problems in heat dissipation and waterproofing. Therefore, a shell with both waterproof and heat dissipation functions is urgently needed. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a shell having both waterproof and heat dissipation functions.
[0005] The utility model solves the above technical problems with the following technical solutions: a waterproof heat dissipation housing, comprising a lower housing, a heat dissipation hole is opened on the rear side of the lower housing, and a surrounding frame surrounding the heat dissipation hole is arranged on the inner side of the lower housing;
[0006] A heat sink is arranged on the inner side of the lower shell, and the heat sink cover is arranged on the surrounding frame.
[0007] The beneficial effects of the utility model are as follows: the heat of the components in the shell is conducted to the heat sink, and the air flow at the heat dissipation holes takes away the heat of the heat sink. At the same time, the heat sink cooperates with the surrounding frame to form a seal, covering the heat dissipation holes to prevent water from entering the shell, thereby achieving both heat dissipation and sealing.
[0008] On the basis of the above technical solution, the present invention can also be improved as follows.
[0009] Furthermore, the surrounding frame is fixedly connected to the inner side of the lower shell, and the heat sink is fixedly installed on the top of the surrounding frame by waterproof glue.
[0010] The beneficial effect of adopting the above further solution is that the waterproof glue allows a good seal between the surrounding frame and the heat sink to prevent water seepage.
[0011] Furthermore, the heat dissipation holes are grid-shaped holes.
[0012] The beneficial effect of adopting the above further solution is that the grille shape is more beautiful, can dissipate heat and protect the inside of the shell.
[0013] Furthermore, the width of a single grille hole of the heat dissipation hole is 0.2mm-0.3mm.
[0014] The beneficial effect of adopting the above further solution is that the smaller the width of the grid is, the more difficult it is for water to enter the shell due to the effect of surface tension.
[0015] Furthermore, a charging port is provided on one side of the lower shell, and a waterproof plug is provided in the charging port.
[0016] The beneficial effect of adopting the above further solution is: the charging port is sealed by a waterproof plug.
[0017] Furthermore, a pin socket is provided on one side of the lower shell, and a waterproof pad is provided in the pin socket.

[0019] Furthermore, it includes an upper shell, and the upper shell and the lower shell are assembled to form a complete shell.
[0020] The beneficial effect of adopting the above further solution is that the upper shell and the lower shell form a complete shell to protect the internal components.
[0021] Furthermore, a waterproof ring is provided on the joint surface of the lower shell and the upper shell.
[0022] The beneficial effect of adopting the above further solution is: the upper shell and the lower shell are sealed by the waterproof ring.
[0023] Furthermore, the heat sink is a copper sheet.
[0024] The beneficial effect of adopting the above further solution is that the copper sheet has good thermal conductivity.
[0025] Furthermore, one end of the heat sink away from the surrounding frame is bent and fits against the inner wall of the lower shell.
