[0002] The exterior walls of a building are an important component of the building, affecting not only its aesthetics but also its performance and lifespan.

[0003] As described in announcement number CN218176741U, a stain-resistant and anti-aging self-cleaning structure for exterior walls includes an exterior wall body. A cleaning device is provided on the side wall of the exterior wall body. The cleaning device includes a servo motor, which is fixedly connected to the side wall of the exterior wall body. A screw is fixedly connected to the output end of the servo motor. A support rod is threadedly connected to the arc surface of the screw. A connecting plate is fixedly connected to the end of the support rod away from the exterior wall body. A rotating rod is rotatably connected inside the connecting plate. A brush is fitted onto the arc surface of the rotating rod. A motor is fixedly connected to the side of the connecting plate away from the support rod, and the output end of the motor is fixedly connected to the rotating rod. By setting up the cleaning device, the device automatically cleans water droplets, preventing water droplets from condensing and adhering to the exterior wall body, thus avoiding the need for users to wipe the exterior wall body regularly and improving the practicality of the device.

[0004] This patent can automatically clean water droplets, preventing water droplets from condensing and adhering to the exterior wall. However, existing devices can only control one side of the cleaning device to lift and clean when cleaning the exterior wall. With prolonged use, the device is prone to deformation, which will affect subsequent cleaning use.

[0005] Therefore, we propose a novel integrated self-cleaning and thermal insulation device for building exterior walls. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing devices, when cleaning exterior walls, can only control the lifting and lowering of one side of the cleaning device, which can easily lead to deformation of the device after prolonged use, thus affecting subsequent cleaning use.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an integrated self-cleaning and thermal insulation device for building exterior walls, comprising an exterior wall body, a self-cleaning component connected to the top of the exterior wall body, the self-cleaning component including a rain shield, seven sets of hot air blowers connected to the bottom surface of the rain shield, a connecting rod inserted inside the exterior wall body, first gears connected to both sides of the connecting rod, an output end of a servo motor fixedly connected to one end of the connecting rod, second gears connected to the bottom surfaces of both sets of first gears, one-way screws connected to the bottom of the second gears, bearings connected to the bottom ends of the one-way screws, lifting blocks connected to the surfaces of both sets of one-way screws, threaded holes penetrating the interior of the lifting blocks, threaded grooves formed inside the front surface of the lifting blocks, a cleaning brush attached to the front outer surface of the lifting blocks, slots formed on both sides of the cleaning brush, and first bolts inserted into the slots.

[0008] Furthermore, the servo motor is electrically connected to an external power source via a control switch, and the output end of the servo motor is fixedly connected to the connecting rod.

[0009] Furthermore, the position and size of the first gear match the position and size of the second gear, and the first gear and the second gear form a meshing connection.

[0010] Furthermore, the lifting block is connected to the one-way screw via a threaded hole, and the one-way screw is connected to the bearing via a rotatable connection.

[0011] Furthermore, the cleaning brush is provided with grooves at the positions where it matches the two sets of lifting blocks, and the first bolt passes through the groove and forms a threaded connection with the threaded groove.

[0012] Furthermore, the outer surfaces on both sides of the lifting block are in contact with the inner wall of the outer wall body.

[0013] Furthermore, the rear end of the main body of the exterior wall is connected to an insulation disassembly assembly, which includes a sliding groove and a slider is provided inside the sliding groove.

[0014] Furthermore, a connecting plate is connected to the rear end of the slider, an insulation layer is connected to one side of the connecting plate, and a decorative layer is connected to one side of the insulation layer.

[0015] Furthermore, a second bolt is inserted at each of the four corners of the decorative layer, the slider is T-shaped, and the slider and the groove form a sliding connection.

[0016] Furthermore, the second bolt penetrates the finishing layer, the insulation layer, and the connecting plate to form a threaded connection with the main body of the exterior wall.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] 1. In this utility model, the automatic cleaning of the exterior wall can be achieved through the timed start function of the servo motor. After the servo motor is started, it can drive two sets of one-way screws to rotate simultaneously through the first gear and the second gear. Then, through the screw rotation, the two sets of lifting blocks can be lifted and lowered simultaneously, thereby driving the cleaning brush to clean water droplets and impurities on the surface of the exterior wall. This improves the stability of the cleaning brush during lifting and cleaning, and avoids the problem that existing devices control the lifting and lowering of one side of the cleaning structure, which can easily lead to deformation of the cleaning structure and affect normal use.

[0019] 2. In this utility model, when installing the insulation layer, the main body of the exterior wall can be installed and fixed first, and then the insulation layer can be installed to the rear end of the main body of the exterior wall by sliding installation and fixed by the second bolt, which improves the insulation effect of the main body of the exterior wall.

Detailed Implementation

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1, such as Figure 1 - Figure 4 As shown, this utility model provides an integrated self-cleaning and thermal insulation device for building exterior walls, including an exterior wall body 1. A self-cleaning component 2 is connected to the top of the exterior wall body 1. The self-cleaning component 2 includes a rain shield 201. Seven sets of hot air blowers 202 are connected to the bottom surface of the rain shield 201. A connecting rod 203 is inserted into the interior of the exterior wall body 1. First gears 204 are connected to both sides of the connecting rod 203. The output end of a servo motor 205 is fixedly connected to one end of the connecting rod 203. Second gears 206 are connected to the bottom surfaces of both sets of first gears 204. A one-way screw 207 is connected to the bottom of the second gear 206. A bearing 208 is connected to the bottom end of the one-way screw 207. Lifting blocks 209 are connected to the surfaces of both sets of one-way screws 207. Threaded holes 210 are formed through the interior of the lifting blocks 209. Threaded grooves 211 are formed inside the front surface of the lifting blocks 209. A cleaning brush 212 is attached to the front outer surface. The cleaning brush 212 has slots 213 on both sides. A first bolt 214 is inserted into the slot 213. The servo motor 205 is electrically connected to an external power supply through a control switch. The output end of the servo motor 205 is fixedly connected to the connecting rod 203. The position and size of the first gear 204 match the position and size of the second gear 206. The first gear 204 and the second gear 206 are meshed. The lifting block 209 is threadedly connected to the one-way screw 207 through the threaded hole 210. The one-way screw 207 is rotatably connected to the bearing 208. The cleaning brush 212 and the two sets of lifting blocks 209 are provided with grooves at their matching positions. The first bolt 214 passes through the slot 213 and is threadedly connected to the threaded groove 211. The outer surfaces of both sides of the lifting block 209 are attached to the inner wall of the outer wall body 1.

[0029] The effect achieved by the entire embodiment 1 is as follows: after the exterior wall body 1 is installed, the timed start function of the servo motor 205 can be set. When the servo motor 205 starts, it will first drive the connecting rod 203 to rotate in reverse through the output end. At the same time, the connecting rod 203 will also drive the two sets of first gears 204 to rotate in reverse. When the two sets of first gears 204 rotate in reverse, they will also drive the two sets of one-way screws 207 to rotate in reverse. This allows the one-way screws 207 to rotate with the lifting block 209 through the threaded hole 210. Then, the threaded rotation will drive the two sets of lifting blocks 209 to move downward at the same time. When the lifting blocks 209 move downward, they will also drive the cleaning brush 212 to move downward, thereby cleaning water droplets and impurities from the exterior wall body 1. When the cleaning brush 212 has cleaned to the bottom, the servo motor 205 will automatically start the forward rotation function, which will then rotate through the gears. The meshing rotation causes the two sets of one-way screws 207 to rotate forward, which in turn drives the cleaning brush 212 to move upward through the two sets of lifting blocks 209, achieving a reset. At this time, the servo motor 205 will automatically shut off. The hot air blower 202 can also be turned on to dry the cleaning brush 212. When the cleaning brush 212 wears out after long-term use and needs to be replaced, the two sets of first bolts 214 can be removed from the threaded grooves 211, the cleaning brush 212 can be disassembled, and the new cleaning brush 212 can be attached to the surface of the two sets of lifting blocks 209. Then, the first bolts 214 can be threaded through the cleaning brush 212 and fixed to the threaded grooves 211. This improves the stability of the cleaning brush 212 during lifting and cleaning, and avoids the problem that the existing device controls the lifting and cleaning of one side of the cleaning structure, which can easily lead to deformation of the cleaning structure and affect normal use.

[0030] Example 2, as Figure 1 and Figure 5 As shown, the rear end of the main body of the exterior wall 1 is connected to an insulation disassembly assembly 3. The insulation disassembly assembly 3 includes a sliding groove 301. A slider 302 is provided inside the sliding groove 301. A connecting plate 305 is connected to the rear end of the slider 302. An insulation layer 304 is connected to one side of the connecting plate 305. A finishing layer 303 is connected to one side of the insulation layer 304. A second bolt 306 is inserted at each of the four corners of the finishing layer 303. The slider 302 is T-shaped. The slider 302 and the sliding groove 301 form a sliding connection. The second bolt 306 passes through the finishing layer 303, the insulation layer 304 and the connecting plate 305 and forms a threaded connection with the main body of the exterior wall 1.

[0031] The effect achieved by the entire embodiment 2 is that when the insulation structure needs to be installed at the rear end of the main body of the exterior wall 1, the slider 302 can be aligned with the groove 301 and slidably installed, and finally fixed by the second bolt 306. The finishing layer 303 mainly plays a decorative and protective role, and the insulation layer 304 is mainly made of rock wool board and glass wool, which has excellent thermal insulation performance and can effectively reduce heat transfer, thereby achieving the effect of wall protection.

[0032] Working principle: The servo motor 205's timed start function enables automatic cleaning of the exterior wall 1. After the servo motor 205 starts, it simultaneously drives two sets of one-way screws 207 to rotate via the first gear 204 and the second gear 206. This screw rotation causes the two sets of lifting blocks 209 to rise and fall simultaneously, thereby driving the cleaning brush 212 to clean water droplets and impurities from the surface of the exterior wall 1. This improves the stability of the cleaning brush 212 during lifting and cleaning. When the cleaning brush 212 wears out after prolonged use and needs replacement, the two sets of first bolts 214 can be removed from the threaded grooves 211. The cleaning brush 212 is disassembled, and a new cleaning brush 212 is attached to the surface of the two sets of lifting blocks 209. Then, the first bolt 214 is threaded through the cleaning brush 212 and fixed with the threaded groove 211. This avoids the problem that the existing device controls the lifting and lowering of the cleaning structure from one side, which can easily lead to deformation of the cleaning structure and affect normal use. When installing the insulation layer 304, the main body of the outer wall 1 can be installed and fixed first, and then the insulation layer 304 can be installed to the rear end of the main body of the outer wall 1 by sliding installation and fixed with the second bolt 306. This improves the insulation effect of the main body of the outer wall 1.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
