DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described below with reference to the accompanying drawings. In the process, in order to ensure the clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0023] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0024] like Figures 1 to 5 As shown, a waterproof switch housing includes a base 1 and a shell 2. A receiving groove 101 is opened in the middle of the upper surface of the base 1. The receiving groove 101 is used to place a circuit board. Three locking holes 102 are opened on the upper surface of the base 1. The three locking holes 102 are all located outside the receiving groove 101. The shell 2 is screwed and locked on the base 1 through three screws passing through the three locking holes 102, and the shell 2 covers the circuit board inside. A wire groove 103 is opened on the upper surface of the base 1. A wire hole 105 is opened at the bottom of the wire groove 103 to facilitate the passage of wires. A glue injection hole 107 is opened at the bottom of the wire groove 103. Sealant is injected into the receiving groove 101 through the glue injection hole 107 to seal and waterproof. A cutting groove 103 is opened on the edge of the upper surface of the base 1 08. A slide groove 104 is provided on the upper surface of the base 1, and the slide groove 104 is located between the cutting groove 108 and the accommodating groove 101. Four first placement holes 106 are provided at the bottom of the slide groove 104. A waterproof rubber strip 3 is slidably provided in the slide groove 104. The shape of the waterproof rubber strip 3 is adapted to the shape of the first placement hole 106. Four second placement holes 31 are provided at the bottom of the waterproof rubber strip 3. A spring 4 is provided in the first placement hole 106, and the top of the spring 4 is located at the bottom of the second placement hole 31. The waterproof rubber strip 3 slides up along the slide groove 104 under the elastic force of the four springs 4, so that the top of the waterproof rubber strip 3 is in contact with the shell 2, thereby enhancing the waterproof effect, effectively preventing external water mist and other liquid droplets from entering the shell 2 to cause a short circuit in the circuit board, and extending the service life of the circuit board.

[0025] like Figure 4As shown, a first placement groove 21 is provided at the bottom of the shell 2, and the first placement groove 21 cooperates with the accommodating groove 101 to close the circuit board for preliminary sealing and waterproofing. The edge of the first placement groove 21 abuts against the cutting groove 108, and a second placement groove 22 is provided at the bottom of the shell 2, and the second placement groove 22 is located outside the first placement groove 21. A sealing groove 24 is provided in the first placement groove 21, and the sealing groove 24 is arranged opposite to the slide groove 104. Under the action of the spring 4, the top of the waterproof rubber strip 3 is clamped into the sealing groove 24, which is further sealed and waterproof, and the waterproof effect is good. A plurality of third placement grooves 23 are provided on the top of the shell 2 for placing and installing corresponding buttons to operate and control various functions.

[0026] The specific implementation method is as follows: by installing the circuit board into the accommodating groove 101 of the base 1, the shell 2 is covered on the base 1 and the circuit board is completely covered. At this time, the edge of the first placement groove 21 abuts against the top of the cut groove 108 of the base 1 to achieve preliminary sealing and waterproofing. Three screws are respectively passed through the three locking holes 102 and screwed into the shell 2 to lock the shell 2 on the base 1. The top of the waterproof strip 3 is clamped in the sealing groove 24 under the action of the spring 4, so as to further seal the circuit board and achieve good waterproof effect. Glue is injected into the waterproof switch through the glue injection hole 107 for sealing. After the glue injection seal and the waterproof strip 3 double seal, the waterproof effect is good, which effectively extends the service life of the circuit board in the waterproof switch housing.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
