Technical Field

[0001] This utility model relates to the technical field of central air conditioning duct cleaning equipment, specifically a central air conditioning duct cleaning device with expandable width. Background Technology

[0002] With the development of modern architecture, central air conditioning systems have been widely used in various commercial, industrial, and large residential buildings. Central air conditioning systems use a complex network of pipes to deliver hot or cold air to different areas to regulate indoor temperature. After prolonged operation, dust, dirt, and other impurities accumulate inside the pipes, which not only affects the cooling and heating efficiency but may also breed bacteria, mold, and other harmful substances, seriously impacting indoor air quality. Therefore, regular cleaning of central air conditioning pipes is essential.

[0003] Currently, the cleaning brush heads in central air conditioning duct cleaning devices on the market have a fixed width. When dealing with cleaning central air conditioning ducts of different models and diameters, they are difficult to adapt to, resulting in poor overall versatility. Furthermore, the fixed-width cleaning structure is not ideal for cleaning the deformed inner walls of the ducts during the cleaning process, and dirt is easily left behind. Utility Model Content

[0004] The purpose of this utility model is to provide a central air conditioning pipe cleaning device with expandable width, so as to solve the problems mentioned in the background art that the fixed-width cleaning structure is difficult to adapt to central air conditioning pipes of different diameters, has poor overall versatility, and the fixed-width cleaning structure is not ideal in cleaning the inner wall of the pipe that undergoes deformation during the pipe cleaning process, and is prone to leaving dirt residue.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a central air conditioning pipe cleaning device with expandable width, including a stepper motor, which is the main power drive component of the pipe cleaning device. The output end of the stepper motor is provided with a connector, and the connector is connected to a cleaning disc, thus forming the main drive equipment structure for cleaning central air conditioning pipes.

[0006] The cleaning disc is bolted with a cleaning plate, and the side wall of the cleaning disc is equidistantly fitted with extension plates. A lifting column is provided between the extension plate and the cleaning disc, and the lifting column is a two-section sliding sleeve structure. The arc-shaped surface of the extension plate and the outer wall of the cleaning plate are both provided with clustered fiber brushes.

[0007] The stepper motor is housed inside the mounting frame, and a positioning box is installed on each of the upper and lower end faces of the mounting frame. A controller is installed inside the positioning box. One end of the height adjustment column is symmetrically installed on the surface of the positioning box, and a limit frame is installed on the other end of the height adjustment column. The limit frame has a groove on its surface, and two dual-output motor shafts are installed in the groove of the limit frame. The output ends of the dual-output motor shafts are connected to the traveling wheels.

[0008] By adopting the above technical solution, the cleaning range can be expanded, and the overall adaptability of the device can be increased.

[0009] Preferably, the surface of the cleaning disc is provided with an annular groove, and the annular groove and the cleaning plate are respectively provided on two surfaces of the cleaning disc, and the side wall of the cleaning disc is engaged with the extension plate. The extension plate is configured as a fan-shaped plate structure and is a plate structure made of silicone.

[0010] Using the above technical solution, the sweeping disc provides installation for the sweeping plate and the extension plate, making it convenient for the extension plate and the sweeping plate to be used together.

[0011] Preferably, the annular groove of the cleaning disc is connected to one end of two connecting frames, and the other end of the connecting frame is connected to the mounting frame through a sleeve. The outer wall of the connecting frame is wound with a spring structure.

[0012] Using the above technical solution, the annular groove of the sweeping disc does not cause the connecting frame to move when the sweeping disc is rotated.

[0013] Preferably, the outer tube of the lifting column is installed inside the cleaning disc, and the output end of the inner tube of the lifting column is connected to the surface of the extension plate.

[0014] Using the above technical solution, as the lifting column extends and retracts, it provides thrust for the extension plate to expand outward.

[0015] Preferably, the mounting bracket has two round holes on its surface, and the two round holes are symmetrically arranged on the same side of the mounting bracket. The round holes of the mounting bracket are connected to the sleeves at the other end of the connecting bracket.

[0016] Using the above technical solution, the connecting frame is provided with installation limit through the circular hole set in the mounting bracket.

[0017] Preferably, the surface of the limiting frame is provided with an arc-shaped opening, which together with the arc-shaped opening on the surface of the positioning box forms a column shape, and the positioning box abuts against the surface of the dual-output motor shaft.

[0018] Using the above technical solution, the opening of the limiting frame and the opening of the positioning box are matched to provide an installation position for the dual-output motor shaft.

[0019] Preferably, the height adjustment column is a two-section sliding sleeve structure, and the height adjustment column is installed on both sides of the dual-output motor shaft.

[0020] By adopting the above technical solution, the height adjustment column and the dual-output motor shaft are installed in a staggered manner to make full use of the internal space of the limit frame.

[0021] Compared with the prior art, the beneficial effects of this utility model are: this expandable width central air conditioning duct cleaning device:

[0022] 1. The cleaning plate set at the front of the cleaning disc cleans the entire device in the forward direction. At the same time, the extension plate installed on the side wall of the cleaning disc is pushed by the lifting column, providing an expandable working range. When cleaning deformed or large-diameter pipes, by adjusting the height of the lifting column, the extension plate can push the arc-shaped cleaning brush to quickly clean the inner wall of the pipe as the cleaning disc rotates. At the same time, the cleaning plate is made of silicone material, which reduces scratches and wear damage to the inner wall of the pipe even when it comes into contact with it, thereby extending the service life of the pipe.

[0023] 2. The positioning box and limit frame set on the surface of the mounting frame are used to adjust the height of the dual-output motor shaft and the traveling wheels. As the extension plate expands outwards, the original height of the equipment no longer matches the working requirements of the extension plate. By adjusting the height between the height adjustment columns, the positioning box and limit frame are opened up, making it easier to adjust the height of the traveling wheels to cooperate with the extended plate as it moves inside the pipe. This ensures that the center of the extension plate remains stable during rotation during the cleaning process, significantly reducing the cleaning difficulty and greatly improving the efficiency of the brush head in removing dirt.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 This utility model provides a technical solution: an expandable width central air conditioning pipe cleaning device, including a stepper motor 1, a connector 2, a cleaning disc 3, a cleaning plate 4, an extension plate 5, a lifting column 6, a connecting frame 7, a mounting frame 8, a positioning box 9, a limiting frame 10, a height adjustment column 11, a dual output motor shaft 12, and a traveling wheel 13.

[0033] Among them, the stepper motor 1 is the main power drive component of the pipe cleaning device. The output end of the stepper motor 1 is provided with a connector 2, and the connector 2 is connected to the cleaning disc 3, thus forming the main drive equipment structure for cleaning pipes of central air conditioning.

[0034] The cleaning disc 3 is bolted with a cleaning plate 4, and extension plates 5 are equidistantly installed on the side wall of the cleaning disc 3. A lifting column 6 is provided between the extension plate 5 and the cleaning disc 3. The lifting column 6 is a two-section sliding sleeve structure. The arc-shaped surface of the extension plate 5 and the outer wall of the cleaning plate 4 are provided with clustered fiber brushes. The surface of the cleaning disc 3 is provided with an annular groove. The annular groove of the cleaning disc 3 and the cleaning plate 4 are respectively provided on two surfaces of the cleaning disc 3. The side wall of the cleaning disc 3 is engaged with the extension plate 5. The extension plate 5 is a fan-shaped plate structure and is made of silicone. The annular groove of the cleaning disc 3 is connected to one end of two connecting frames 7, and the other end of the connecting frame 7 is connected to the mounting frame 8 through a sleeve. The outer wall of the connecting frame 7 is wound with a spring structure. The outer tube of the lifting column 6 is installed inside the cleaning disc 3, and the output end of the inner tube of the lifting column 6 is connected to the surface of the extension plate 5.

[0035] Referring to the attached diagrams in the instruction manual Figure 1-6As shown, during use, the stepper motor 1 is connected via cable to the operator's control equipment or the power system within the cleaning area. The connector 2 at the output end of the stepper motor 1 provides mounting for the sweeping disc 3, facilitating quick replacement during continuous cleaning. The connecting bracket 7, installed within the annular groove of the sweeping disc 3, enhances the connection with the mounting bracket 8. One end of the connecting bracket 7 slides against the sleeve. A buffer space is reserved at the connection between the stepper motor 1 and the connector 2. When the front end of the sweeping disc 3 is intercepted or subjected to external impact, the connecting bracket 7 provides a buffer area for the stepper motor 1 and the mounting bracket 8. The sweeping plate 4, bolted to the surface of the sweeping disc 3, has an area that can be adjusted as needed. Figure 1-2 As shown, the clustered fiber brushes installed on both the arc-shaped surface of the extension plate 5 and the outer wall of the cleaning plate 4 make the fiber brushes diffuse, which facilitates thorough cleaning of the inner wall of the pipe. The extension plate 5 is pushed outward by the lifting column 6, which makes the fiber brushes of the extension plate 5 fit better against the inner wall of the pipe for cleaning.

[0036] The stepper motor 1 is installed inside the mounting frame 8, and a positioning box 9 is installed on the upper and lower end faces of the mounting frame 8 respectively. The positioning box 9 is equipped with a controller. One end of the height adjustment column 11 is symmetrically installed on the surface of the positioning box 9, and the other end of the height adjustment column 11 is equipped with a limit frame 10. The surface of the limit frame 10 is provided with an arc-shaped opening, which forms a column shape with the arc-shaped opening on the surface of the positioning box 9. The positioning box 9 abuts against the surface of the dual output motor shaft 12. The surface of the limit frame 10 is provided with a groove, and two dual output motor shafts 12 are provided in the groove of the limit frame 10. The output end of the dual output motor shaft 12 is connected to the travel wheel 13. The surface of the mounting frame 8 is provided with two round holes, which are symmetrically arranged on the same side surface of the mounting frame 8. The round holes of the mounting frame 8 are connected to the sleeves connected to the other end of the connecting frame 7. The height adjustment column 11 is a two-section sliding sleeve structure, and the height adjustment column 11 is installed on both sides of the dual output motor shaft 12.

[0037] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, the dual-output motor shaft 12 and the traveling wheel 13 constitute a complete forward drive device structure, which is then installed between the positioning box 9 and the limit frame 10, as... Figure 4-6 As shown, the height is adjusted by the extension and retraction of the height adjustment column 11 set between the positioning box 9 and the limit frame 10. The height adjustment column 11 is an electrically driven lifting rod device. Since there are two sets of dual-output motor shafts 12 and traveling wheels 13, the height adjustment column 11 and the lifting column 6 are adjusted synchronously on the dual-output motor shafts 12 and traveling wheels 13 above the stepper motor 1. This allows the extension plate 5 to adjust the height of the mounting frame 8 while expanding, so that the mounting frame 8 carrying the stepper motor 1 is located in the center of the pipeline, and the auxiliary cleaning disc 3 is kept stable and rotates for cleaning.

[0038] Working Principle: When using this expandable width central air conditioning duct cleaning device, the stepper motor 1 is connected to the operator's control equipment via a wire, simultaneously providing power to the forward drive device consisting of the dual-output motor shaft 12 and the traveling wheels 13. This facilitates the movement of the entire device within the central air conditioning duct. During use, the height of the dual-output motor shaft 12 and the traveling wheels 13 moves synchronously with the limit frame 10. The limit frame 10 is adjusted by the raising and lowering of the height adjustment column 11. The height adjustment column 11 and the lifting column 6 start synchronously. With consistent process length and speed, when cleaning central air conditioning pipes with larger inner diameters is required, the lifting column 6 pushes the extension plate 5 outward, allowing the cleaning brushes on the arc-shaped surface of the extension plate 5 to contact the inner wall of the central air conditioning pipes. Through the rotation of the output end of the stepper motor 1 and the transfer through the connector 2, the cleaning disc 3 drives the extension plate 5 to rotate synchronously. The cleaning plate 4 set on the surface of the cleaning disc 3 handles the dirt in the forward direction. By adjusting the position of the extension plate 5, the position of the inner diameter of the pipe is accurately matched, increasing the overall practicality.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
