[0001] The present application relates to the technical field of bathroom power supplies, and in particular, to a waterproof structure for a bathroom power supply. Background Art
[0002] As an important part of bathroom products, due to the special use environment of bathroom power supplies, they often come into contact with water. The waterproof performance of bathroom power supplies is directly related to the overall quality of the products and the user experience. Therefore, extremely high requirements are put forward for the waterproof performance of bathroom power supplies.
[0003] Existing bathroom power supplies generally include a bottom shell, a PCB board installed on the inner bottom wall of the bottom shell, and a face shell covering the bottom shell. One end of the bottom shell is provided with an interface for wiring. The interface is connected to a power input line and a power output line that are electrically connected to the PCB board. The power input line is externally connected to a power supply with a rated voltage of 220V. A corresponding conversion circuit is provided on the PCB board, and this conversion circuit is used to convert the rated voltage into a low voltage so that the power output line can output a low voltage.

[0007] A waterproof structure for a bathroom power supply includes a bottom shell with an opening at the top and a face shell covering the opening of the bottom shell. One end of the bottom shell is provided with an interface for wiring. A limiting shell is fixedly connected to the inner bottom wall of the bottom shell and at the end of the bottom shell close to the interface. A fixing module for eliminating the stress of the wire and preventing the core wire at the wire connection from breaking is limited in the limiting shell. A first waterproof groove is provided on the circumferential side of the top surface of the bottom shell. A waterproof frame that is inserted and matched with the first waterproof groove is fixedly connected to the circumferential side of the bottom surface of the face shell. A second waterproof groove communicating with the first waterproof groove is provided on the top surface of the limiting shell. A waterproof block that is inserted and matched with the second waterproof groove is fixedly connected to the bottom surface of the face shell.

[0010] By adopting the above technical solution, the limiting blocks are arranged to limit the fixing module between the limiting blocks and the interface.
[0011] Preferably, a glue filling groove is formed between one side of the limiting shell and the limiting block. When the fixing module is limited between the limiting block and the interface, glue is poured into the glue filling groove to form a glue layer in the glue filling groove.
[0012] By adopting the above technical solution, the existence of the glue layer prevents water from entering the bottom shell from the interface and also plays a role in fixing the fixing module.
[0013] Preferably, a waterproof strip that abuts against the top surface of the fixing module is fixedly connected to the bottom surface of the front shell.

[0017] Preferably, a connecting block is fixedly connected to the bottom surface of the front shell, a bayonet is formed on the connecting block, and a clamping block that is in clamping fit with the connecting block is fixedly connected to the inner wall of the bottom shell.
[0018] By adopting the above technical solution, the front shell is fixed to the bottom shell through the clamping fit of the clamping block and the bayonet.
[0019] Preferably, there are two connecting blocks, and the two connecting blocks are respectively located at two diagonal corners of the bottom surface of the front shell. The number of clamping blocks is the same as that of the connecting blocks and they correspond one by one.
[0020] By adopting the above technical solution, the arrangement of the two connecting blocks makes the front shell more firmly fixed to the bottom shell.
[0021] Preferably, a power input line and a power output line are fixedly connected to the fixing module, a PCB board is installed on the inner bottom wall of the bottom shell, and both the power input line and the power output line are electrically connected to the PCB board.
[0022] By adopting the above technical solution, the power input line is externally connected to a power supply with a rated voltage of 220V. Since the power input line and the power output line are both electrically connected to the PCB board, and a conversion circuit is provided on the PCB board, the power output line can output a low voltage converted by the PCB board.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. Place the fixed module with wires in the limit shell, then cover the top shell on the opening of the bottom shell. At this time, the waterproof frame is inserted into the first waterproof groove, and the waterproof block is inserted into the second waterproof groove, so as to prevent water from entering the bottom shell from the interface, so as to improve the waterproof performance of the bathroom power supply;
[0025] 2. The glue layer prevents water from entering the bottom shell from the interface and also serves to fix the module;
[0026] 3. The advantages of ultrasonic welding technology include being fast, clean, requiring no additional adhesives or solvents, and being able to achieve high-strength and well-sealed connections. BRIEF DESCRIPTION OF THE DRAWINGS
