DETAILED DESCRIPTION OF THE INVENTION

[0021] The following clearly and completely describes the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to the attached Figures 1-5 , a central air-conditioning cleaning device in this embodiment: It includes a dust collection box 1, a connecting pipe 2 is fixedly connected inside the dust collection box 1, a support rod 3 is fixedly connected to the outer end of the connecting pipe 2, a protective shell 4 is provided at the other end of the support rod 3, a cleaning assembly is rotatably connected inside the protective shell 4, a water spraying hole is provided on the protective shell 4 above the cleaning assembly, a water inlet pipe 5 is fixedly connected to the upper end of the protective shell 4, a collection groove 6 is provided on the protective shell 4 below the cleaning assembly, a water outlet pipe 7 is fixedly communicated with the bottom of the collection groove 6, and the water outlet pipe 7 is communicated with the connecting pipe 2; the cleaning assembly includes a cleaning belt 8, bristles are installed on the outer side of the cleaning belt 8, driving rollers 9 are provided at both ends inside the cleaning belt 8, and two brush cleaning rollers 10 are rotatably connected inside the protective shell 4, and the brush cleaning rollers 10 are located behind the cleaning belt 8.

[0023] The connecting pipe 2 connects the outside and the inside of the dust collection box 1. One end of the connecting pipe 2 is located at the bottom of the dust collection box 1, and the other end of the connecting pipe 2 is connected to the support rod 3. The connecting pipe 2 is a corrugated pipe with good flexibility and foldability. The rear end of the protective shell 4 is connected to the support rod 3. The cleaning assembly is located at the front end of the protective shell 4. A high-pressure nozzle is installed in the water spray hole. The water inlet pipe 5 is connected to the external water circuit. The high-pressure nozzle atomizes the sprayed water flow, and at the same time increases the water flow impact force to enhance the cleaning effect. The cleaning assembly is located below the water spray hole. The cleaning belt 8 in the water spray assembly rotates unidirectionally and cleans in one direction during cleaning, avoiding splashing dust and cleaning wastewater randomly. At the same time, it can better sweep the dust and cleaning wastewater into the collection tank 6 below. The bottom of the collection tank 6 is connected to the water outlet pipe 7, and the water outlet pipe 7 is connected and communicated. The support rod 3 is a rod body with an inner hole. The water outlet pipe 7 discharges the sewage into the dust collection box 1 through connection with the support rod 3, avoiding sewage splashing. There are two driving rollers 9 in the cleaning assembly. The two driving rollers 9 tighten the cleaning belt 8, and the rotation of the two driving rollers 9 drives the unidirectional rotation of the cleaning belt 8. The inner side of the cleaning belt 8 is a friction surface, which can increase the friction coefficient with the driving roller 9. The outer side of the cleaning belt 8 is bristles. The bristles have good deformation ability and can better penetrate into the inner layer of the central air conditioner during cleaning. To ensure the cleaning effect of the cleaning belt 8, two brush cleaning rollers 10 are installed at the rear side of the cleaning belt 8. The two brush cleaning rollers 10 rotate synchronously with the cleaning belt 8. When the bristles on the cleaning belt 8 pass through the brush cleaning rollers, the bristles and the brush cleaning rollers interact, and the brush cleaning rollers clean the bristles on the cleaning belt 8, so that the bristles on the cleaning belt 8 maintain the cleanliness of the bristles when contacting the central air conditioner, enabling the bristles to better clean the central air conditioner.

[0024] The outer side of the cleaning belt 8 is flush with the rear side of the protective shell 4. Further, in order to adjust the protruding distance of the cleaning belt 8 relative to the protective shell 4, adjusting frames 14 are installed on both sides of the two driving rollers 9. The adjusting frames 14 play a supporting role for the two driving rollers 9. The adjusting frames 14 can slide in the chute of the protective shell 4, and the adjusting frames 14 are fixed in the chute by screws. The movement and fixation of the adjusting frames 14 are completed by tightening and loosening the screws. The driving roller 9 and the brush cleaning roller move synchronously. A first belt pulley 11 is connected to the driving roller 9, and a second belt pulley 12 is connected to the brush cleaning roller. The first belt pulley 11 and the second belt pulley 12 are synchronously driven by a connecting belt 13.

[0025] The anti-overflow plate 15 is an arc-shaped structure. The anti-overflow plate 15 protrudes forward relative to the protective shell 4. During use, the anti-overflow plate 15 is located below the cleaning assembly, which can effectively avoid the overflow of the falling sewage, achieve a better collection effect on the cleaning sewage, and facilitate the cleaning work after air conditioner cleaning.

[0026] The angle between the protective shell 4 and the support rod 3 can be adjusted, which can make the protective shell 4 better aligned with the cleaning part during actual use. A sleeve 17 is sleeved on the support rod 3, and the vertical movement of the sleeve 17 drives the vertical movement of the connecting rod 16. When the connecting rod 16 moves upward, the connecting rod 16 drives the protective shell 4 to rotate upward relative to the support rod 3. On the contrary, when the connecting rod 16 moves downward, the connecting rod 16 drives the protective shell 4 to rotate downward, thus realizing the angle adjustment of the protective shell 4.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
