[0020] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0021] like Figure 3-5 As shown, an air-conditioning evaporator cleaning structure includes an air-conditioning evaporator 1, an outer sealing plate 2 and a sliding block 3. The sliding blocks 3 are arranged as a symmetrical group, each group consists of two. The tops of the two sliding blocks 3 are fixedly connected with a connecting rod 305. A telescopic groove 309 is penetrated through the middle of the sliding block 3. A connecting column 2 303 is movably connected to the inner wall of the telescopic groove 309. A connecting column 1 304 is rotatably connected between the two connecting columns 2 303. The sliding block 3 is elastically connected to the connecting column 2 303 through a spring column 302. The outer wall of the connecting column 2 303 and the inner part of the spring column 302 are fixedly connected with a limiting rod 301. The limiting rod 301 is penetrated and connected with the sliding block 3.

[0022] According to the above structure, the connecting column 2 303 can slide elastically inside the telescopic groove 309 through the spring column 302, and the limiting rod 301 assists in limiting its sliding to prevent tilting and dislocation during sliding. The rotation or movement of the sliding block 3 can be controlled by the connecting rod 305, and when the sliding block 3 moves, the connecting column 1 304 will move with it.

[0023] Refer to the attached Figure 2-5 A cleaning brush 306 is fixedly connected to the connecting column 304 at an equal distance on one side close to the air-conditioning evaporator 1. The bottom of the outer sealing plate 2 is integrally cast with an arc bend 208 for adapting the rotation of the sliding block 3. The two sides of the outer sealing plate 2 are symmetrically fixedly connected with the wave plate 203. The connecting column 304 is movably fitted on one side of the wave plate 203. The outer walls of the outer sealing plate 2 and the arc bend 208 are provided with a sliding groove 204. The sliding block 3 is slidably connected to the sliding groove 204 through a sliding bar 307. An embedding rod 308 is fixedly connected to one end of the sliding bar 307. The inner wall of the sliding groove 204 is symmetrically provided with an embedding groove 205 for the embedding rod 308 to slide and engage.

[0024] According to the above structure, the sliding block 3 is slidably connected to the sliding groove 204 through the sliding bar 307, the sliding block 3 is rotated to make it perpendicular to the outer sealing plate 2, the embedded rod 308 follows the sliding block 3 and rotates in the embedded groove 205 in the arc bend 208 at the same time, and then the sliding block 3 is slid. The connecting column 304 is affected by the shape of the wave plate 203 and will move back and forth during the sliding process. The connecting column 304 drives the cleaning brush 306 to move between the fins of the air-conditioning evaporator 1 to frictionally clean the fins.

[0025] See attached Figure 1 , Figure 5 The outer sealing plates 2 are symmetrically fixedly assembled on both sides of the air-conditioning evaporator 1, and the tops of the two outer sealing plates 2 are fixedly connected with top sealing plates 201. The end of the wave plate 203 close to the arc bend 208 is integrally provided with a placement groove 207 for sliding and fitting the connecting column 304. A placement plate 202 for supporting a cleaning brush 306 is fixedly connected between the two outer sealing plates 2 and located below the air-conditioning evaporator 1. The outer wall of the outer sealing plate 2 is fixedly connected with a magnetic suction plate 206 for magnetic adsorption with the sliding block 3, and the magnetic suction port of the magnetic suction plate 206 is set to be L-shaped.

[0026] According to the above structure, after the cleaning work is completed, the sliding block 3 is lowered to make it slide to the bottom of the air-conditioning evaporator 1, and the connecting column 304 is finally slid and engaged in the placement groove 207, and the cleaning brush 306 is placed on the placement plate 202, and the sliding block 3 is rotated to make it parallel to the outer sealing plate 2. The magnetic plate 206 uses its L-shaped shape to support and adsorb the sliding block 3 to prevent the sliding block 3 from rotating or sliding; the utility model can drive the cleaning brush 306 to brush between the fins of the air-conditioning evaporator 1 through the sliding of the sliding block 3, and the cleaning brush 306 can automatically circulate and retract while cleaning the fins, thereby enhancing the cleaning effect of adhering stains, and can properly place the cleaning brush 306 and the sliding block 3 after the cleaning work is completed, saving space and avoiding affecting the normal operation of the air-conditioning evaporator 1.

[0027] The working principle of the utility model is as follows: the second connecting column 303 can slide elastically in the telescopic groove 309 through the spring column 302, and the limiting rod 301 can assist in limiting its sliding to prevent tilting and dislocation during the sliding process. The rotation or movement of the sliding block 3 can be controlled by the connecting rod 305. When the sliding block 3 moves, the connecting column 1 304 will move with it; the sliding block 3 is slidably connected to the sliding groove 204 through the sliding bar 307, the sliding block 3 is rotated to make it perpendicular to the outer sealing plate 2, and the embedded rod 308 follows the sliding block 3 and rotates in the embedded groove 205 in the arc bend 208 at the same time, and then the sliding block is slid. 3. The connecting column 304 is affected by the shape of the wave plate 203 and will move back and forth during the sliding process. The connecting column 304 drives the cleaning brush 306 to move between the fins of the air-conditioning evaporator 1 to clean the fins by friction. After the cleaning work is completed, the sliding block 3 is lowered to slide to the bottom of the air-conditioning evaporator 1. The connecting column 304 is finally slid and engaged in the placement groove 207. The cleaning brush 306 is placed on the placement plate 202. The sliding block 3 is rotated to make it parallel to the outer sealing plate 2. The magnetic suction plate 206 uses its L-shaped shape to support and adsorb the sliding block 3 to prevent the sliding block 3 from rotating or sliding.

[0028] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
