[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the cooperation of the conical flushing shell, adjusting shell, extension shell, threaded limiting cylinder, pressure groove, return spring, and extrusion plate, the spray direction of the nozzle can be flexibly adjusted. When it is necessary to clean air conditioning ducts of different diameters or degrees of curvature, the threaded limiting cylinder is rotated to move forward of the conical flushing shell, thereby pushing the extension shell. The extension shell flips inside the adjusting port to adjust the angle. The extension shell pushes the extrusion plate, which in turn squeezes the return spring, thus limiting the adjustment shell from continuing to flip. The extrusion plate and threaded limiting cylinder position the extension shell, thereby adjusting the nozzle position. This achieves the purpose of flexibly adjusting the nozzle direction according to different duct conditions, avoiding the problem of some areas not being effectively cleaned and the cleaning coverage being limited due to the inflexible adjustment of the nozzle.

[0017] 2. Through the coordinated operation of the sealed bearings, U-shaped tubes, eccentric balls, spiral inner cavity, and spray head in the rotating spray unit, and the micro motor, drive shaft, ring frame, brushes, and first and second ball bearings in the cleaning unit, the inner wall of the air duct can be cleaned more comprehensively and efficiently. The pressure pump delivers water from the water tank to the spray head through the first steel wire braided rubber hose, the steel wire braided rubber main connecting pipe, and the second steel wire braided rubber hose. When the water is sprayed out from the spray head under the action of the spiral inner cavity, it produces a rotating spray effect. At the same time, the micro motor drives the drive shaft to rotate, causing the brush on the ring frame to rotate and brush the inner wall of the air duct. The combination of these two components cleans the air duct from all angles, improving the cleaning effect and avoiding the problem of incomplete cleaning affecting the operation of the air conditioning system.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0028] Please see Figures 1-6 The system includes a water tank 1, a control button 2 fixedly connected to the front of the water tank 1, a pressure pump 3 fixedly connected to the upper surface of the water tank 1, a first steel wire braided rubber hose 4 fixedly connected to the output end of the pressure pump 3, a handle 5 fixedly connected to the outer surface of the first steel wire braided rubber hose 4, and a rinsing unit provided at one end of the first steel wire braided rubber hose 4.

[0029] The rinsing unit includes a steel wire braided rubber main connecting pipe 10 fixedly connected to one end of a first steel wire braided rubber hose 4. A conical rinsing shell 7 is provided on the outside of the water storage tank 1. Six adjustment ports 21 are opened on the outer surface of the conical rinsing shell 7. Six pressure grooves 22 are opened on the inner wall of the water storage tank 1. An adjustment shell 14 is rotatably connected to the inner wall of each adjustment port 21. An extension shell 12 is fixedly connected to the outer surface of each adjustment shell 14. A rotating spraying unit is provided on the outside of the conical rinsing shell 7. A second steel wire braided rubber hose 15 is fixedly connected to the outer surface of each adjustment shell 14. One end of each second steel wire braided rubber hose 15 is fixedly connected to one end of the steel wire braided rubber main connecting pipe 10. A threaded limiting cylinder 6 is threadedly connected to the outer surface of the conical rinsing shell 7. The outer surface of each extension shell 12 is in contact with one end of the threaded limiting cylinder 6.

[0030] Specifically, when the cleaning device is started, the operator holds the handle 5 and presses the control button 2. The pressure pump 3 starts to work and draws water from the water storage tank 1. The water is then transported to the rinsing unit through the first steel wire braided rubber hose 4 to provide water for subsequent cleaning. This solves the water supply problem of the cleaning device and realizes the initial water flow transportation work.

[0031] In the rinsing unit, water flows through the first steel wire braided rubber hose 4 into the steel wire braided rubber main connecting pipe 10, and then through the second steel wire braided rubber hose 15 to the extension shells 12 connected to each adjusting shell 14. If the nozzle angle needs to be adjusted, the threaded limiting cylinder 6 is rotated, and the threaded limiting cylinder 6 moves forward to push the extension shell 12. The extension shell 12 flips in the adjusting port 21, driving the adjusting shell 14 to rotate and adjust the nozzle position. This meets the cleaning needs of ducts with different diameters and curvatures, avoiding the problem of some areas not being cleaned due to the inflexible adjustment of the nozzle, and realizing flexible adjustment of the nozzle angle.

[0032] Please see Figures 1-6 Each pressure groove 22 has a fixedly connected return spring 17 on its inner wall, and a fixedly connected squeezing plate 16 at one end of each return spring 17. The outer surface of each squeezing plate 16 is slidably connected to the inside of the pressure groove 22, and the outer surface of each squeezing plate 16 is in contact with the outer surface of the adjusting shell 14. A cleaning unit is also provided on the outside of the conical flushing shell 7.

[0033] Specifically, under the action of the pressure groove 22, the return spring 17 and the squeezing plate 16, when the extension shell 12 rotates, the squeezing plate 16 slides in the pressure groove 22 and squeezes the return spring 17. The elastic force of the return spring 17 provides a reverse force, which, together with the threaded limit cylinder 6, positions the extension shell 12, so that the adjusted nozzle position remains stable. This solves the problem of unstable positioning after nozzle adjustment and ensures that the nozzle angle will not change arbitrarily during the cleaning process.

[0034] Please see Figures 1-6 The rotary spraying unit includes a sealed bearing 25 fixedly connected to the inner wall of each extended shell 12. Each sealed bearing 25 has a U-shaped tube 26 fixedly connected to its inner ring. One end of each U-shaped tube 26 is fixedly connected to an eccentric ball 11. Each eccentric ball 11 has a spiral inner cavity 24 on its inner wall. The outer surface of the U-shaped tube 26 is fixedly connected to the inner wall of the spiral inner cavity 24. The inner wall of the eccentric ball 11 and the inner wall of the spiral inner cavity 24 are both fixedly connected to a spray head 23.

[0035] Specifically, after the water flows into the extension shell 12, it enters the U-shaped tube 26 through the sealed bearing 25, and then flows into the spiral inner cavity 24 of the eccentric ball 11. Under the action of the spiral inner cavity 24 and the U-shaped tube 26, the water produces a rotating spray effect when it is sprayed out from the spray head 23, which washes the inner wall of the air duct and scours the inner wall of the air duct from multiple angles, thereby improving the coverage and cleanliness of the cleaning and achieving the purpose of efficiently cleaning the inner wall of the air duct.

[0036] Please see Figures 1-6 The cleaning unit includes a micro motor 20 fixedly connected to the inner wall of the conical flushing shell 7. The output end of the micro motor 20 is fixedly connected to a drive shaft 19. An annular frame 9 is fixedly connected to the outer surface of the drive shaft 19. A first ball bearing 18 is fixedly connected to the inner wall of the conical flushing shell 7. The outer surface of the first ball bearing 18 is fixedly connected to the inner wall of the annular frame 9. Multiple brushes 8 are fixedly connected to the outer surface of the annular frame 9. The control button 2 is electrically connected to the pressure pump 3 and the micro motor 20 respectively through wires.

[0037] Specifically, control button 2 controls the micro motor 20 to start, the micro motor 20 drives the transmission shaft 19 to rotate, the transmission shaft 19 drives the ring frame 9 to rotate under the support of the first ball bearing 18, the brush 8 on the ring frame 9 rotates accordingly, and scrubs the inner wall of the air duct. Combined with the water flow sprayed from the spray head 23, the cleaning effect is further enhanced, solving the problem that simple water spraying is not thorough, and ensuring that the inner wall of the air duct is cleaner.

[0038] Please see Figures 1-6 The inner wall of the conical flushing shell 7 is fixedly connected to a second ball bearing 27. The inner ring of the second ball bearing 27 is fixedly connected to the outer surface of the drive shaft 19. The outer surfaces of the six second steel wire braided rubber hoses 15 are jointly fixedly connected to a fixing plate 13. The outer surface of the fixing plate 13 is fixedly connected to the inner wall of the conical flushing shell 7.

[0039] Specifically, the second ball bearing 27 further enhances the stability of the rotation of the drive shaft 19, and the six second steel wire braided rubber hoses 15 are fixedly connected to the inner wall of the conical flushing shell 7 through the fixing plate 13, ensuring the stability of the entire flushing unit structure, enabling each component to operate stably during operation, avoiding the impact of structural instability on the cleaning work, and ensuring the reliable operation of the cleaning device.

[0040] Working principle:

[0041] When the cleaning device is started, the operator holds handle 5 and presses control button 2. Pressure pump 3 starts working, drawing water from water tank 1 and delivering it to the rinsing unit through the first braided rubber hose 4. The water flows through the first braided rubber hose 4 into the main braided rubber connecting pipe 10, and then through the second braided rubber hose 15 to the extension shells 12 connected to each adjusting shell 14. If the nozzle angle needs to be adjusted, the threaded limiting cylinder 6 is rotated. The threaded limiting cylinder 6 moves forward, pushing the extension shell 12. The extension shell 12 flips in the adjusting port 21, causing the adjusting shell 14 to rotate and adjusting the nozzle position. At this time, the squeezing plate 16 slides in the pressure groove 22 and squeezes the return spring 17. The elastic force of the return spring 17, together with the threaded limiting cylinder 6, positions the extension shell 12, keeping the adjusted nozzle position stable. After the water flows into the extension shell 12, it passes through... The sealed bearing 25 enters the U-shaped tube 26 and then flows into the spiral inner cavity 24 of the eccentric ball 11. Under the action of the spiral inner cavity 24 and the U-shaped tube 26, the water sprayed from the spray head 23 produces a rotating spray effect, which washes the inner wall of the air duct. At the same time, the control button 2 controls the micro motor 20 to start. The micro motor 20 drives the transmission shaft 19 to rotate. The transmission shaft 19 drives the ring frame 9 to rotate under the support of the first ball bearing 18 and the second ball bearing 27. The brush 8 on the ring frame 9 rotates accordingly to brush the inner wall of the air duct. This, combined with the water flow sprayed from the spray head 23, further enhances the cleaning effect. The six second steel wire braided rubber hoses 15 are fixedly connected to the inner wall of the conical flushing shell 7 through the fixing plate 13, ensuring the stability of the entire flushing unit structure. Finally, it achieves comprehensive, efficient and stable cleaning of air conditioning air ducts with different diameters and curvatures.

[0042] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
