[0042] like Figure 1-Figure 5 As shown, an embodiment of the present application provides an electrical appliance box, including: a housing 1, an electronic component 2, a button 3 and a first waterproof membrane 4.

[0043] The housing 1 has a cavity 11 and a pressing hole 12 communicating with the cavity 11 .

[0044] The electronic component 2 is disposed in the cavity 11 .

[0045] The button 3 is movably connected to the housing 1 . The button 3 has a pressing portion. The button 3 can move toward the housing 1 so as to trigger the electronic component 2 through the pressing hole 12 .

[0046] The first waterproof membrane 4 is disposed between the button 3 and the housing 1 , and the first waterproof membrane 4 blocks the pressing hole 12 .

[0047] The pressing portion can trigger the electronic component 2 through the first waterproof membrane 4 .

[0048] In the present application, by setting a first waterproof membrane 4 between the button 3 and the shell 1, the first waterproof membrane 4 can effectively fill the gap between the button 3 and the shell 1, and can effectively prevent humid air from entering the shell 1 through the gap between the shell 1 and the button 3, thereby preventing the electronic components 2 inside the shell 1 from getting damp and extending the service life. At the same time, the button 3 can normally trigger the electronic components 2 through the first waterproof membrane 4, and will not affect the normal use of the electrical box.

[0049] Specifically, the electrical box triggers the electronic component 2 through the pressing portion of the button 3, thereby realizing the function of the electronic component 2. The electrical box is an alarm. When an alarm is required, by pressing the button 3, the pressing portion of the button 3 triggers the electronic component 2, thereby triggering the alarm. Of course, the electrical box can also be other electrical appliances that trigger the electronic component 2 to work through the button 3.

[0050] At present, people have put forward higher requirements for smart homes, which are usually based on residential platforms, combining architecture, network communication, information appliances, equipment automation, integrating systems, structures, services, and management, and have the advantages of high efficiency, comfort, safety, convenience, and environmental protection. In addition, through the superposition of network superposition, screen superposition, information superposition, and other aspects, a convenient and comfortable living environment that is easy to communicate with the outside and easy to control internally can be achieved, so as to control the terminal equipment to realize the application of smart homes. However, in the south of my country, the weather is humid, and because there is a gap between the button 3 of the electrical box and the shell 1, humid air can easily enter the shell 1 through the gap, causing the electronic components 2 inside the shell 1 to be damp, thereby affecting the service life of the electronic components 2, or making the electronic components 2 unable to function normally, affecting the user experience.

[0051] In the embodiment of the present application, a first waterproof membrane 4 is provided between the button 3 and the housing 1, and the first waterproof membrane 4 can block the pressing hole 12, preventing external humid air from entering the housing 1 through the gap between the button 3 and the housing 1 and the pressing hole 12, thereby protecting the electronic components 2 in the housing 1, preventing the electronic components 2 from getting damp, and extending the service life of the electronic components 2. Moreover, the pressing portion of the button 3 can trigger the electronic components 2 through the first waterproof membrane 4, and will not hinder the normal operation of the electrical box.

[0052] In some embodiments, a receiving groove 13 is provided on the housing 1 , the receiving groove 13 is connected to the cavity 11 through the pressing hole 12 , the first waterproof membrane 4 is provided in the receiving groove 13 , and the button 3 is movably provided in the receiving groove 13 .

[0053] In the present application, by arranging the first waterproof membrane 4 in the receiving groove 13, the effective fitting area between the first waterproof membrane 4 and the housing 1 can be increased, so that part of the first waterproof membrane 4 can block the pressing hole 12, and the remaining part can fit with the housing 1, further improving the waterproof effect. The button 3 is movably arranged in the receiving groove 13, and by pressing the button 3, the pressing part of the button 3 can squeeze the first waterproof membrane 4, thereby triggering the electronic component 2 through the first waterproof membrane 4.

[0054] In some embodiments, the first waterproof membrane 4 has a fixing portion 41 that is in contact with the inner surface of the accommodating groove 13 and an extending portion 42 that is opposite to the pressing hole 12. The extending portion 42 is located at the center of the first waterproof membrane 4, and the fixing portion 41 is located on the outer peripheral side of the extending portion 42. The pressing portion triggers the electronic component 2 through the extending portion 42.

[0055] In the present application, the extending portion 42 of the first waterproof membrane 4 is used to cooperate with the pressing portion of the button 3. The pressing portion of the button 3 triggers the electronic component 2 through the extending portion 42. By arranging a fixing portion 41 around the extending portion 42, the fixing portion 41 fits with the inner surface of the accommodating groove 13, which can further improve the isolation effect and prevent humid air from entering the shell 1 and affecting the electronic component 2.

[0056] Specifically, the first waterproof membrane 4 is made of a silicone-fluorine coating membrane, which is a coating composed of silicone rubber and fluoropolymer, and has the characteristics of oxidation resistance and strong plasticity. In the receiving groove 13, it is deformed by extrusion and fills the gap between the button 3 and the receiving groove 13, thereby forming a natural insulating layer.

[0057] like Figure 3 As shown, in a specific embodiment, the extension portion 42 is ductile, and the extension portion 42 can be deformed when pressed by the pressing portion, so that the pressing portion triggers the electronic component 2 .

[0058] In the present application, the extending portion 42 itself has ductility. When the pressing portion of the button 3 acts on the extending portion 42, the extending portion 42 itself can be deformed, thereby achieving that the pressing portion of the button 3 can smoothly trigger the electronic component 2, and the structural strength of the extending portion 42 is not guaranteed, thereby avoiding the extending portion 42 from being broken due to frequent contact with the pressing portion of the button 3 in the later stage, thereby further ensuring the waterproof effect.

[0059] Specifically, the extension portion 42 has the ability to extend and deform, and when the key 3 loses the external force, the extension portion 42 can be reset under its own elastic deformation ability, thereby lifting the key 3, so that the key 3 is separated from the electronic component 2. There is no need to set a reset elastic member for the key 3, and the structure is simpler.

[0060] like Figure 4 As shown, in another specific embodiment, the first waterproof membrane 4 also includes an extension portion 43 arranged between the extension portion 42 and the fixed portion 41, and the extension portion 43 is extensible. When the pressing portion presses the extension portion 42, the extension portion is deformed so that the pressing portion triggers the electronic component 2.

[0061] In the present application, by providing an extension part 43 between the extension part 42 and the fixed part 41, when the pressing part of the key 3 acts on the extension part 42, the extension part 42 does not deform, but deforms through the extension part 43, so that the pressing part can smoothly trigger the electronic component 2, and the waterproof effect can be ensured. In addition, the material of the extension part 42 can be strengthened at this time to further prevent the extension part 42 that abuts against the pressing part of the key 3 from being broken due to direct action with the pressing part, thereby ensuring the structural strength and service life of the first waterproof membrane 4.

[0062] Specifically, through the extension part 43 with elastic deformation ability, when the button 3 loses the external force, the extension part is reset under the elastic deformation ability, so as to lift the button 3, so that the button 3 is separated from the electronic component 2. That is, the first waterproof membrane 4 at this time can also play the function of resetting the button 3, making the structure simpler, and there is no need to set a reset elastic member for the button 3 separately.

[0063] like Figure 5 As shown, in another specific embodiment, the first waterproof membrane 4 also includes a telescopic portion 44 arranged between the stretching portion 42 and the fixed portion 41, and the telescopic portion 44 includes a contracted state and a tensioned state. When the pressing portion presses the stretching portion 42, the telescopic portion 44 is in a tensioned state, and when the pressing portion is separated from the stretching portion 42, the telescopic portion 44 is in a contracted state.

[0064] In the present application, a telescopic portion 44 is provided between the extension portion 42 and the fixing portion 41, and the telescopic portion 44 includes a contracted state and a tensioned state. When the pressing portion and the extension portion 42 act, the telescopic portion 44 is expanded to a tensioned state, ensuring that the pressing portion can smoothly trigger the electronic component 2. In addition, the first waterproof membrane 4 can be provided with a material having stronger structural performance, thereby increasing the service life of the first waterproof membrane 4.

[0065] In a preferred embodiment, the first waterproof membrane 4 in the present application is made of elastic material as a whole, and the entire first waterproof membrane 4 has the ability to be elastically deformed. After being arranged in the receiving groove 13, under the action of the key 3, the first waterproof membrane 4 is squeezed and deformed and fully fits with the receiving groove 13 of the housing 1, filling the gap between the key 3 and the housing 1, thereby forming a natural insulation layer.

[0066] In some embodiments, the button 3 is connected to the housing 1 magnetically.

[0067] In the present application, the button 3 is connected to the housing 1 through a strong magnet, thereby preventing the button 3 from escaping from the receiving groove 13 . When the button 3 is pressed downward, the pressing portion of the button 3 triggers the electronic component 2 through the extending portion 42 .

[0068] Specifically, an annular magnet (not shown) may be disposed in the receiving groove 13, and the annular magnet is disposed around the key 3. The key 3 may be made of magnetic material, or a magnetic member may be disposed on the key 3. The annular magnet and the key 3 made of magnetic material or the magnetic member on the key 3 are attracted by magnetic force, thereby preventing the key 3 from being separated from the receiving groove 13. Moreover, by disposing the annular magnet around the key 3, the key 3 can be positioned in the axial direction. When the key 3 loses the external force, the key 3 is reset under the action of the magnetic force, thereby separating the key 3 from the electronic component 2.

[0069] In some embodiments, a limiting portion is disposed in the receiving groove 13 , and the limiting portion is used to limit the button 3 along the axial direction of the receiving groove 13 .

[0070] In the present application, a limiting portion may be provided in the receiving groove 13, and a notch corresponding to the limiting portion may be provided on the key 3. When the key 3 is installed, the notch is aligned with the limiting portion, so that the key 3 can be installed in the receiving groove 13. After the key 3 is installed, the key 3 can be limited by rotating the key 3 so that the limiting portion and the notch are misaligned, thereby preventing the key 3 from being separated from the receiving groove 13.

[0071] In some embodiments, a power supply chamber 14 connected to the cavity 11 is provided in the shell 1, a power supply body 5 is provided in the power supply chamber 14, the power supply body 5 is electrically connected to the electronic component 2, and the electrical box also includes a second waterproof membrane 6 arranged between the power supply body 5 and the electronic component 2.

[0072] In the present application, the power supply body 5 provides electrical energy to the electronic component 2 to ensure the normal operation of the electronic component 2. By setting a second waterproof membrane 6 between the electronic component 2 and the power supply body 5, the humid air in the power supply chamber 14 can be prevented from entering the cavity 11 and affecting the electronic component 2. The first waterproof membrane 4 and the second waterproof membrane 6 seal the cavity 11 into an enclosed space, which can further improve the waterproof effect and improve the waterproof protection of the electronic component 2.

[0073] Specifically, the second waterproof membrane 6 is made of waterproof silica gel, and the diameter of the second waterproof membrane 6 is larger than the power supply body 5, so that the second waterproof membrane 6 can effectively isolate the power supply body 5 and the electronic component 2. The power supply body 5 is electrically connected to the electronic component 2 through the positive and negative connectors.

[0074] Among them, in the present application, the cavity 11 is made into a closed space by the first waterproof membrane 4 and the second waterproof membrane 6, so that the circuit board of the electronic component 2 is in a sealed space and is not affected by water droplets, condensation, and steam, thereby ensuring the electrical safety of the speaker, button 3, smart module and battery on the circuit board in the sealed space.

[0075] In an optional embodiment, a waterproof gasket 8 is provided between the second waterproof membrane 6 and the power supply body 5 , and the waterproof gasket 8 can support the power supply body 5 and ensure the stability of the power supply body 5 in the power supply chamber 14 .

[0076] In some embodiments, the housing 1 includes: an upper housing 15, a lower housing 16 and a bottom housing 17.

[0077] The lower shell 16 is buckled and connected to the upper shell 15 , and a cavity 11 is formed between the upper shell 15 and the lower shell 16 . The lower shell 16 is provided with a power chamber 14 and a take-in and put-out port communicating with the power chamber 14 .

[0078] The bottom shell 17 is detachably disposed at the access opening.

[0079] In the present application, a take-and-drop opening is provided on the lower shell 16 to facilitate replacement of the power supply body 5. When replacing the power supply body 5, first remove the bottom shell 17, then take the power supply body 5 out of the power supply chamber 14, replace it with a new power supply body 5, and then install the bottom shell 17 to the take-and-drop opening.

[0080] In the related art, in the north, due to the cold weather, the battery life of the power supply body 5 is limited, and the electronic component 2 is easily affected by the power supply body 5 storage problem and the user experience effect.

[0081] In the present application, a separate access port is provided, and the opening and closing of the access port is controlled by the bottom shell 17, so that the power supply body 5 can be replaced conveniently.

[0082] Specifically, a first snap-in position is provided on the lower shell 16 , and a second snap-in position is provided on the bottom shell 17 . The first snap-in position is snap-fitted with the second snap-in position, thereby achieving effective connection between the bottom shell 17 and the lower shell 16 , making it convenient to disassemble and assemble the bottom shell 17 .

[0083] In some embodiments, a boss structure 171 is disposed on the bottom shell 17 , and the electrical box further includes a waterproof foam 7 disposed on the boss structure 171 , and the waterproof foam 7 is connected to the bottom shell 17 and the lower shell 16 respectively.

[0084] In the present application, the power source body 5 still has the problem of poor waterproofness. When humid air enters the battery chamber, it is easy to affect the power source body 5, causing the battery life of the power source body 5 to decrease.

[0085] In the present application, a waterproof foam 7 is provided, and the waterproof foam 7 is provided at the boss structure 171. After the bottom shell 17 and the lower shell 16 are installed and fixed, the two ends of the waterproof foam 7 are respectively abutted against the lower shell 16 and the bottom shell 17. Due to the extrusion force, the waterproof foam 7 between the lower shell 16 and the bottom shell 17 changes from a "I" shape to a "T" shape, which can effectively block small gaps and play a role in dust and water prevention.

[0086] In some embodiments, the electrical box is an alarm, and the alarm triggers the electronic component 2 via the button 3 to generate alarm information.

[0087] In the present application, the electrical box is an alarm. When the electronic component 2 is triggered by the pressing portion of the button 3, the electronic component 2 generates an alarm message and issues an alarm, wherein the alarm can be in the form of sending the alarm message to the platform.

[0088] In some embodiments, the electronic component 2 includes a sending module, and the sending module is used to send the alarm information to the user terminal.

[0089] In the present application, by setting up an intelligent sending module on the electronic component 2, the generated alarm information can be sent directly to the user terminal, and the alarm information can be sent to the community, user, police area, etc., to improve the alarm effect.

[0090] In the present application, by setting a first waterproof membrane 4 between the button 3 and the shell 1, the first waterproof membrane 4 can effectively fill the gap between the button 3 and the shell 1, and can effectively prevent humid air from entering the shell 1 through the gap between the shell 1 and the button 3, thereby preventing the electronic components 2 inside the shell 1 from getting damp and extending the service life. At the same time, the button 3 can normally trigger the electronic components 2 through the first waterproof membrane 4, and will not affect the normal use of the electrical box.

[0091] At present, people have put forward higher requirements for smart homes, which are usually based on residential platforms, combining architecture, network communication, information appliances, equipment automation, integrating systems, structures, services, and management, and have the advantages of high efficiency, comfort, safety, convenience, and environmental protection. In addition, through the superposition of network superposition, screen superposition, information superposition, and other aspects, a convenient and comfortable living environment that is easy to communicate with the outside and easy to control internally can be achieved, so as to control the terminal equipment to realize the application of smart homes. However, in the south of my country, the weather is humid, and because there is a gap between the button 3 of the electrical box and the shell 1, humid air can easily enter the shell 1 through the gap, causing the electronic components 2 inside the shell 1 to be damp, thereby affecting the service life of the electronic components 2, or making the electronic components 2 unable to function normally, affecting the user experience.

[0092] In the embodiment of the present application, a first waterproof membrane 4 is provided between the button 3 and the housing 1, and the first waterproof membrane 4 can block the pressing hole 12, preventing external humid air from entering the housing 1 through the gap between the button 3 and the housing 1 and the pressing hole 12, thereby protecting the electronic components 2 in the housing 1, preventing the electronic components 2 from getting damp, and extending the service life of the electronic components 2. Moreover, the pressing portion of the button 3 can trigger the electronic components 2 through the first waterproof membrane 4, and will not hinder the normal operation of the electrical box.
