In the embodiments of the present utility model, the electric appliance box 100 includes a circuit board 110, a first housing 120, a second housing 130, a first waterproof member 140, and a waterproof film 150.

[0041] The surface of the first housing 120 is provided with a button 121. The first housing 120 is detachably connected to the second housing 130, so that the first housing 120 and the second housing 130 form a receiving cavity, and the circuit board 110 is disposed in the receiving cavity. A first waterproof member 140 is disposed at the connection between the first housing 120 and the second housing 130 to isolate the receiving cavity from the outside. The waterproof film 150 has a protruding portion 151, and the shape of the protruding portion 151 matches the shape of the button 121, so that the waterproof film 150 is closely attached to the surface of the first housing 120.

[0042] In this embodiment, the first waterproof member 140 seals the connection between the first housing 120 and the second housing 130 to isolate the receiving cavity from the outside. The waterproof film 150 covers the surface of the first housing 120 to block the gap at the button 121 located on the surface of the first housing 120. The waterproof film 150 cooperates with the first waterproof member 140, so that when the first housing 120 and the second housing 130 are in a connected state, the circuit board 110 located in the receiving cavity is isolated from the outside, preventing external liquid from flowing into the receiving cavity and causing damage to the circuit board 110.

[0043] The protruding portion 151 of the waterproof film 150 matches the shape of the button 121. When the waterproof film 150 covers the surface of the first housing 120, the button 121 can extend into the groove 124 formed by the protruding portion 151, so that the waterproof film 150 can be completely attached to the surface of the first housing 120 and the button 121, improving the waterproof property of the waterproof film 150. At the same time, through the setting of the protruding portion 151 of the waterproof film 150, it is also very convenient to attach the waterproof film 150 to the surface of the first housing 120, improving the assembly efficiency. Among them, the waterproof film 150 is a PET (polyethylene terephthalate) film.

[0044] The first waterproof member 140 of the electrical box 100 in the embodiment of the present invention can seal the gap at the connection between the first housing 120 and the second housing 130. The shape of the protruding portion 151 of the waterproof film 150 matches the shape of the button 121, so that the waterproof film 150 is closely attached to the surface of the first housing 120, isolating the surface of the first housing 120 from the outside. Through the first waterproof member 140 and the waterproof film 150, the inside of the electrical box 100 can be isolated from the outside. At the same time, the setting of the protruding portion 151 of the waterproof film 150 facilitates the waterproof film 150 to be closely attached to the surface of the first housing 120. By the first waterproof member 140, the gap at the connection between the first housing 120 and the second housing 130 can be sealed, reducing the waterproof parts of the electrical box 100 and facilitating assembly.

[0045] In some embodiments, the electrical appliance box 100 further includes an electrical connector 200 and a second waterproof member 160. A first opening 101 is provided on the side wall of the first housing 120 or the second housing 130. The electrical connector 200 is disposed at the first opening 101, and the second waterproof member 160 is sleeved on the electrical connector 200.

[0046] In this embodiment, one end of the electrical connector 200 is electrically connected to the circuit board 110, and the other end extends outside the electrical appliance box 100, so that the circuit board 110 can be electrically connected to an external power supply. When the circuit board 110 does not need to be electrically connected to an external device, the second waterproof member 160 is sleeved on the electrical connector 200 to isolate the electrical connector 200 from the outside, preventing external liquid from flowing into the electrical connector 200 or infiltrating into the circuit board 110 through the electrical connector 200.

[0047] In some embodiments, the electrical appliance box 100 further includes a communication member 190 and a third waterproof member 170. A second opening 102 is provided on the side wall of the first housing 120 or the second housing 130. The communication member 190 is disposed at the second opening 102, and the third waterproof member 170 is sleeved on the electrical connector 200.

[0048] In this embodiment, one end of the communication member 190 is electrically connected to the circuit board 110, and the other end extends outside the electrical appliance box 100, so that the circuit board 110 can be communicatively connected to an external device. The third waterproof member 170 is sleeved on the communication member 190 to isolate the communication member 190 from the outside, so that while the circuit board 110 is communicatively connected to the outside through the communication member 190, it can also prevent external liquid from flowing into the communication member 190 or infiltrating into the circuit board 110 through the communication member 190. Among them, the communication member 190 can be an antenna module such as a WiFi module or a Bluetooth module that can generate and receive radio signals.

[0049] In some embodiments, the electrical appliance box 100 further includes two fourth waterproof members 180, which are respectively disposed between the second waterproof member 160 and the first opening 101 and between the third waterproof member 170 and the second opening 102, so as to isolate the first opening 101 and the second opening 102 from the outside.

[0050] In this embodiment, the fourth waterproof member 180 seals the gaps between the second waterproof member 160 and the first opening 101 and between the third waterproof member 170 and the second opening 102, improving the sealing performance of the electrical appliance box 100 and avoiding a reduction in the sealing performance of the electrical appliance box 100 caused by improper installation of the second waterproof member 160 and the third waterproof member 170.

[0051] Further, the first waterproof member 140, the second waterproof member 160, the third waterproof member 170, and the fourth waterproof member 180 are made of silicone material, rubber material, or other waterproof elastic materials.

[0052] In some embodiments, the first housing 120 includes a plurality of limiting portions 122, and the second housing 130 includes a plurality of corresponding limiting grooves 131. The limiting portions 122 are disposed on the surface of the first housing 120 facing the second housing 130 and extend towards the second housing 130. The limiting portions 122 can extend into the corresponding limiting grooves 131, so that the first housing 120 and the second housing 130 are detachably connected.

[0053] In this embodiment, the limiting portion 122 can extend into the corresponding limiting groove 131, so that the first housing 120 is limited to the second housing 130 and connected to the second housing 130. Through the corresponding arrangement of the limiting portion 122 and the limiting groove 131, the first housing 120 and the second housing 130 can be correctly connected, and the first waterproof member 140 is clamped between the first housing 120 and the second housing 130.

[0054] Specifically, a connecting member with a threaded structure can connect and fix the first housing 120 and the second housing 130 by extending into the limiting portion 122 and the limiting groove 131.

[0055] In some embodiments, the surface of the first housing 120 facing the second housing 130 includes a plurality of first pressing portions 123, and the surface of the second housing 130 facing the first housing 120 includes a plurality of corresponding second pressing portions 132. In a state where the first housing 120 and the second housing 130 are connected, the first waterproof member 140 is located between the first pressing portion 123 and the second pressing portion 132.

[0056] In this embodiment, the shape of the first pressing portion 123 matches the shape of the second pressing portion 132, and the shape of the first waterproof member 140 matches the shapes of the first pressing portion 123 and the second pressing portion 132. By disposing the first waterproof member 140 on the first pressing portion 123 or the second pressing portion 132, when the first housing 120 and the second housing 130 approach and connect with each other through the limiting portion 122 and the limiting groove 131, the first waterproof member 140 can be clamped between the first pressing portion 123 and the second pressing portion 132, so that the first waterproof member 140 seals the gap at the connection between the first housing 120 and the second housing 130.

[0057] In some embodiments, the limiting portion 122 is disposed on the edge portion of the first housing 120, the limiting groove 131 is disposed on the edge portion of the second housing 130, the first pressing portion 123 is respectively connected to two adjacent side walls of the first housing 120 to form a first limiting structure surrounding the limiting portion 122, and the second pressing portion 132 is respectively connected to two adjacent side walls of the second housing 130 to form a second limiting structure surrounding the limiting groove 131.

[0058] In this embodiment, the first pressing portion 123 is disposed at the four peripheral edges of the first housing 120, and the second pressing portion 132 is disposed at the edge of the second housing 130, so that the limiting portions 122 at the four corners of the first housing 120 are surrounded by the first limiting structure, and the limiting grooves 131 at the four corners of the second housing 130 are surrounded by the second limiting structure. When the first housing 120 and the second housing 130 are connected, the first limiting structure and the second limiting structure can separate the limiting portions 122 and the limiting grooves 131 from the accommodation cavity, preventing liquid from flowing into the accommodation cavity due to water leakage from the limiting portions 122 or the limiting grooves 131.

[0059] In some embodiments, in the connected state of the first housing 120 and the second housing 130, the first limiting structure, the second limiting structure, the side wall of the first housing 120 and the side wall of the second housing 130 form the side wall of the accommodation cavity.

[0060] In this embodiment, when the first housing 120 and the second housing 130 are connected, the first limiting structure and the second limiting structure separate the limiting portions 122 and the limiting grooves 131 from the accommodation cavity. At the same time, since the first limiting structure and the second limiting structure are distributed at the four corners of the first housing 120 and the second housing 130, the first limiting structure, the second limiting structure, the side wall of the first housing 120 and the side wall of the second housing 130 are connected as a whole to form the side wall of the accommodation cavity. Therefore, the accommodation cavity can still form a complete cavity, avoiding the first limiting structure and the second limiting structure from separating the accommodation cavity into different small cavities, ensuring the space size of the accommodation cavity, and enabling the circuit board 110 to be smoothly placed in the accommodation cavity.

[0061] In some embodiments, the first pressing portion 123 has a groove 124 extending along its surface. The height of the second pressing portion 132 is the same as the height of the side wall of the second housing 130. In the state where the first housing 120 and the second housing 130 are connected, the first waterproof member 140 is clamped by the first pressing portion 123 and the second pressing portion 132 in the groove 124 of the first pressing portion 123.

[0062] In this embodiment, the first waterproof member 140 can be placed in the groove 124 of the first pressing portion 123, so that the first waterproof member 140 can be accurately positioned on the first pressing portion 123. In the state where the first housing 120 and the second housing 130 are connected, the first pressing portion 123 and the second pressing portion 132 clamp the first waterproof member 140 therein. Through the setting of the groove 124, it is possible to prevent the first waterproof member 140 from being misaligned or unable to be accurately fixed between the first pressing portion 123 and the second pressing portion 132, ensuring that the first waterproof member 140 can stably and accurately seal the gap between the first pressing portion 123 and the second pressing portion 132.

[0063] In some embodiments, a third opening 103 is further provided on the surface of the first housing 120. The circuit board 110 includes an indicator light 111, and the light-emitting end of the indicator light 111 is disposed at the third opening 103.

[0064] In this embodiment, the light-emitting ends of the plurality of indicator lights 111 are exposed to the outside through the corresponding third openings 103. The waterproof film 150 of the present application is transparent or semi-transparent, so that the light generated by the light-emitting ends of the indicator lights 111 can smoothly pass through the waterproof film 150, ensuring that the electrical box 100 can normally display the indication emitted by the indicator lights 111.

[0065] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
