[0016] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0017] like Figure 1-9 As shown, a prefabricated kitchen and bathroom waterproof wall panel for decoration includes a wall 1 and a grid frame assembled on one side of the wall 1, a plurality of installation windows are opened on the grid frame, and wall panel units 3 are installed inside the plurality of installation windows. When the wall panel units 3 are installed inside the installation windows, the side walls of the grid frame can extend toward the direction close to the side walls of the wall panel units 3, so as to fill the gap between the elastic sealing frame 2 and the wall panel units 3, so that the elastic sealing frame 2 and the plurality of wall panel units 3 form an integral waterproof wall panel with fewer gaps, thereby improving the waterproof sealing performance of the waterproof wall panel.

[0018] Here, one side of the wall 1 can be fixedly connected with multiple fixing rings 13 located inside the installation window, one side of the wall 1 and inside the fixing ring 13 can be fixedly connected with a first magnet 32, and the side of the wall panel unit 3 close to the wall 1 can be fixedly connected with a second magnet 33, the second magnet 33 can be snapped into the inside of the fixing ring 13, and the first magnet 32 ​​and the second magnet 33 are magnetically attracted to each other. At this time, the stability of the wall panel unit 3 when fixed can be enhanced by the fixing ring 13 and the first magnet 32.

[0019] Here, the wall panel unit 3 can be any one of a metal panel, a glass magnesium panel, a FRP glass fiber reinforced plastic panel and a PVC plastic waterproof wall panel.

[0020] like Figure 1-2 The grid frame includes an air pressure regulating mechanism and a plurality of elastic sealing frames 2 fixedly connected to one side of the wall 1. The plurality of elastic sealing frames 2 are preferably in a rectangular array. A plurality of installation windows are respectively opened on the plurality of elastic sealing frames 2. An air guide cavity 5 is opened inside the elastic sealing frame 2. The air pressure regulating mechanism is communicated with the plurality of air guide cavities 5. At this time, when the wall panel unit 3 is installed inside the installation window, the air pressure regulating mechanism can be used to inflate the inside of the air guide cavity 5, so that the elastic sealing frame 2 expands to abut against the side wall of the wall panel unit 3, thereby fixing the wall panel unit 3 and reducing the gap between the elastic sealing frame 2 and the wall panel unit 3.

[0021] Among them, the air pressure regulating mechanism can be an air pump, which is connected to multiple air guide cavities 5. The air pressure inside the air guide cavity 5 can be adjusted by starting the air pump, and the air pressure inside the air guide cavity 5 can be maintained by the air pump.

[0022] Specifically, the material of the elastic sealing frame 2 can be any one of butyl rubber, silicone rubber and polyurethane elastomer, preferably butyl rubber, which has good waterproofness, air tightness, chemical corrosion resistance, elasticity and durability, and is suitable for coastal areas. The outer side of the elastic sealing frame 2 can be provided with a fluorocarbon coating or a polyurethane coating to further extend the service life of the elastic sealing frame 2.

[0023] like Figure 2 As shown, the outer side of the wall panel unit 3 can be fixedly connected with a connecting frame 6, and the side wall of the connecting frame 6 away from the wall panel unit 3 is provided with a first fitting surface 7, and the circumferential side opposite to the elastic sealing frame 2 and the first fitting surface 7 can be provided with a contoured fitting portion 8 adapted to the first fitting surface 7, and the side opposite to the contoured fitting portion 8 and the first fitting surface 7 is a second fitting surface, and the cross-sections of the second fitting surface and the contoured fitting portion 8 can both be wavy. By setting the structure of the first fitting surface 7 and the contoured fitting portion 8, the sealing between the wall panel unit 3 and the elastic sealing frame 2 can be further improved, and the stability of the wall panel unit 3 when fixed inside the elastic sealing frame 2 can be improved.

[0024] like Figure 1-3 As shown, multiple elastic sealing frames 2 are arranged in a circular array, and a four-way valve 4 is installed between four adjacent elastic sealing frames 2. The four-way valve 4 is fixedly connected to one side of the wall 1, and the four elastic sealing frames 2 are all connected to the four-way valve 4. At this time, the multiple elastic sealing frames 2 can be formed into an interconnected structure through the four-way valve 4, which is convenient for the air pump to adjust the air pressure as a whole.

[0025] The four-way valve 4 can be a normally open valve or a normally closed valve. In the present technical solution, a normally closed valve is preferred.

[0026] like Figure 1-3 As shown, the four-way valve 4 includes a valve body 9 fixedly connected to one side of the wall 1, four arc-shaped connecting surfaces 10 are arranged on the peripheral side of the valve body 9, and the elastic sealing frame 2 is fixedly connected to the arc-shaped connecting surface 10, so that the valve body 9 and the elastic sealing frame 2 are connected together, so that a plurality of elastic sealing frames 2 form an integral structure, and connecting pipes 11 are fixedly connected to the four arc-shaped connecting surfaces 10, and the air guide cavities 5 of the four elastic sealing frames 2 are respectively connected to the four connecting pipes 11, so that the four elastic sealing frames 2 on the peripheral side of the four-way valve 4 can be connected to each other through the four-way valve 4; like Figure 2 and Figure 4-5 As shown, the interior of the valve body 9 is fixedly connected with an outer annular partition 14 and an inner annular partition 15 located on the inner side of the outer annular partition 14. The space between the outer annular partition 14 and the inner annular partition 15 is a connecting chamber 23. Four first blocking blocks 20 are installed inside the connecting chamber 23. The four first blocking blocks 20 are respectively opposite to the four connecting pipes 11. When the first blocking blocks 20 and the connecting pipes 11 are against each other, the connecting pipes 11 can be blocked. Four electric adjustment groups are also installed inside the valve body 9. The four electric adjustment groups are respectively connected to the four first blocking blocks 20. At this time, the first blocking blocks 20 can be driven to move by starting the electric adjustment groups to control whether the first blocking blocks 20 block the connecting pipe 11.

[0027] Here, the assembled kitchen and bathroom waterproof wall panels may also include a control host, and the air pump and the electric adjustment group are electrically connected to the control host. At this time, the actions of the air pump and the electric adjustment group can be controlled by starting the control host.

[0028] like Figure 2 and Figure 4-5As shown, the space inside the inner annular partition 15 is an installation cavity 24, and the electric adjustment group includes an electromagnet 16 fixedly connected to the installation cavity 24, and the end of the electromagnet 16 close to the first blocking block 20 is fixedly connected to the first return spring 17, and the end of the first return spring 17 away from the electromagnet 16 is fixedly connected to the connecting plate 18, and the end of the connecting plate 18 away from the first return spring 17 is fixedly connected to the support rod 19, and a sliding circular hole is opened on the inner annular partition 15, and the end of the support rod 19 away from the connecting plate 18 slides into the interior of the connecting cavity 23 through the sliding circular hole and is fixedly connected to the first blocking block 20. At this time, in daily use, the elasticity of the first return spring 17 drives the first blocking block 20 to move to abut against the connecting pipe 11, so that the four connecting pipes 11 can all enter the normally closed state, so that the multiple elastic sealing frames 2 are independent of each other in daily use. After one of the elastic sealing frames 2 is accidentally damaged, the phenomenon of overall deflation failure of the multiple elastic sealing frames 2 is reduced.

[0029] At the same time, the air pump and the electric adjustment group can be turned on at a fixed time by controlling the host to adjust the internal pressure of the air guide cavity 5.

[0030] Furthermore, an exhaust valve connected to the connecting chamber 23 may be further provided on the valve body 9. When one of the wall panel units 3 needs to be replaced, the corresponding connecting pipe 11 is switched to an open state, and the elastic sealing frame 2 on the outside of the wall panel unit 3 can be deflated through the exhaust valve, so that the volume of the elastic sealing frame 2 shrinks, and a gap is generated between the wall panel unit 3, so that the wall panel unit 3 can be disassembled and replaced relatively simply.

[0031] like Figure 3 and Figure 6 As shown, the exhaust valve includes a second return spring 21 fixedly connected to the inside of the connecting cavity 23, and a through hole 12 connected to the connecting cavity 23 can be opened on the side of the valve body 9 away from the wall 1, and a second blocking block 22 is fixedly connected to the end of the second return spring 21 close to the through hole 12. Under the elastic action of the second return spring 21, the second blocking block 22 and the through hole 12 are abutted against each other to seal the through hole 12, and when the second blocking block 22 is pressed, the deflation can be completed.

[0032] At the same time, a trumpet shell 25 located outside the second block 22 is fixedly connected to the inner wall of the valve body 9. The trumpet shell 25 can increase the contact area between the second block 22 and the valve body 9, thereby improving the sealing performance.

[0033] like Figure 1 and Figure 7-8As shown, the assembled kitchen and bathroom waterproof wall panels can also include an air pressure stabilizing mechanism, which includes an air storage shell 26, one end of the air storage shell 26 and the air guide cavity 5 are connected via an air guide pipe 27, the interior of the air storage shell 26 is slidably connected with an air push plate 29, and a third return spring 31 is installed inside the air storage shell 26 and at the end of the air push plate 29 away from the air guide pipe 27. At this time, the space inside the air storage shell 26 and between the air guide pipe 27 and the air push plate 29 is a stabilizing space, and under the elastic force of the third return spring 31, the size of the stabilizing space can be adjusted by moving the air push plate 29, so that the air pressure of the elastic sealing frame 2 is controlled by using the gas inside the stabilizing space.

[0034] One end of the air storage shell 26 away from the air guide pipe 27 is threadedly connected with a screw rod 28, and one end of the screw rod 28 located inside the air storage shell 26 is rotatably connected to a spring mounting plate 30. The spring mounting plate 30 and one end of the third return spring 31 away from the air push plate 29 are fixedly connected. At this time, by rotating the screw rod 28 to adjust the position of the spring mounting plate 30, the spring mounting plate 30 can be driven to move, thereby adjusting the elasticity of the third return spring 31.

[0035] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
