Description

Technical Field

[0001] This utility model relates to the field of central air conditioning technology, specifically to a dust collection device for cleaning central air conditioning systems. Background Technology

[0002] Central air conditioning is an integrated air conditioning system that combines cooling, heating, and ventilation. It uses a centralized duct system distributed throughout a building to deliver treated air to various rooms, thus achieving overall air conditioning control. A central air conditioning system mainly consists of a cold / heat source system and an air conditioning system. The cold / heat source system provides the cooling or heating required for cooling or heating, while the air conditioning system is responsible for delivering the treated air to the rooms.

[0003] Existing vacuum cleaners are effective at cleaning flat, large-area components like central air conditioning filters, but their cleaning performance is relatively limited when dealing with components with complex, curved designs, such as central air conditioning ducts. The design of central air conditioning ducts often includes multiple curved and arc-shaped surfaces. These non-planar structures make it difficult for the suction power of the vacuum cleaner to be evenly distributed, thus affecting the removal of deep-seated dirt inside and on the surface of the central air conditioning duct.

[0004] Therefore, we propose a vacuum cleaning device for central air conditioning systems to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum cleaning device for central air conditioning systems to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vacuum cleaner for cleaning central air conditioning, comprising a cleaning bucket, a snap-fit ​​top cover above the top cover, and a wind duct body disposed in the inner cavity of the cleaning bucket. An annular air duct is fixedly connected to the inner wall of the cleaning bucket, and multiple sets of high-pressure jet pipes are fixedly connected to the surface of the annular air duct. An air pipe is fixedly connected to the surface of the annular air duct, and the air pipe extends through the surface of the cleaning bucket to the outside.

[0007] The bottom of the cleaning bucket cavity is equipped with a telescopic column, and a motor is fixedly connected to the top of the top cover. The output end of the motor passes through the top cover and is fixedly connected to a linkage rod. The other end of the linkage rod and the telescopic column are both fixedly connected to a locking block. The linkage rod and the telescopic column are fixed to the air duct body in the cleaning bucket cavity through the locking block.

[0008] Preferably, a rotating seat is fixedly connected to the bottom of the inner cavity of the cleaning bucket, and the telescopic column is rotatably connected to the bottom of the inner cavity of the cleaning bucket through the rotating seat.

[0009] Preferably, a base is fixedly connected to the surface of the cleaning bucket.

[0010] Preferably, the bottom of the inner cavity of the cleaning bucket is provided with two sets of ventilation grooves.

[0011] Preferably, a control valve is fixedly connected to the bottom of the cleaning bucket, and the control valve covers the two sets of ventilation slots.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Compressed air is smoothly and evenly injected into the annular air duct through the air pipe. Upon receiving the gas, the high-pressure jet pipe rapidly ejects high-pressure gas. This high-speed flowing gas acts directly on the surface of the duct body with extremely high impact force, effectively stripping off the dust and impurities adhering to it. The duct body itself is also constantly rotating. This exposes all surfaces of the duct body to the impact of high-pressure gas, thereby improving the uniformity and comprehensiveness of the cleaning. Furthermore, the centrifugal force can dislodge some loosened dust and impurities from the surface of the duct body, further enhancing the cleaning effect. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-3This utility model provides a technical solution: a vacuum cleaner for cleaning central air conditioning, including a cleaning bucket 1, a top cover 2 that snaps onto the top cover 21, and a blower body 3 set in the inner cavity of the cleaning bucket 1. After the blower body 3 is placed on the telescopic column 6 in the inner cavity of the cleaning bucket 1, the telescopic column 6 supports it. The top cover 2 and the cleaning bucket 1 are tightly closed to form a closed working environment, which helps to reduce the splashing of dust or impurities that may be generated during the cleaning process, thereby protecting the surrounding environment and improving work efficiency.

[0020] The extension and retraction of the telescopic column 6 pushes the air duct body 3 to move. The locking block 9, which is connected to the linkage rod 8 and the telescopic column 6, locks the air duct body 3. When the motor 7 is started, it drives the linkage rod 8 to rotate. The linkage rod 8, through the transmission action of the locking block 9, drives the air duct body 3 inside the cleaning bucket 1 to rotate synchronously.

[0021] For details, please refer to Figure 1-3 Compressed air is smoothly and evenly injected into the annular air duct 4 through the air pipe. Upon receiving the gas, the high-pressure jet pipe 5 rapidly ejects high-pressure gas. This high-speed flowing gas acts directly on the surface of the air duct body 3 with extremely high impact force, effectively peeling off the dust and impurities adhering to it. The air duct body 3 itself is also constantly rotating. This exposes all surfaces of the air duct body 3 to the impact of the high-pressure gas, thereby improving the uniformity and comprehensiveness of the cleaning. Furthermore, the centrifugal force can fling some loosened dust and impurities off the surface of the air duct body 3, further enhancing the cleaning effect. After the initial treatment of the surface of the air duct body 3 is completed, the control valve 12 is opened to connect the suction pipe. With the opening of the control valve 12, the dust and impurities cleaned by the high-pressure jet pipe 5 are rapidly sucked in and collected through the suction pipe.

[0022] Working Principle: After the air duct body 3 is placed on the telescopic column 6 inside the cleaning barrel 1, the telescopic column 6 supports it, and the top cover 2 tightly seals with the cleaning barrel 1, forming a closed working environment. This helps reduce the splashing of dust or impurities that may be generated during the cleaning process, thereby protecting the surrounding environment and improving work efficiency. The extension and retraction of the telescopic column 6 pushes the air duct body 3 to move. The locking block 9 connected to the linkage rod 8 and the telescopic column 6 locks the air duct body 3. When the motor 7 is started, it drives the linkage rod 8 to rotate. The linkage rod 8, through the transmission action of the locking block 9, drives the air duct body 3 inside the cleaning barrel 1 to rotate synchronously. Compressed air is smoothly and evenly injected into the annular air duct 4 through the air pipe. After receiving the gas, the high-pressure jet pipe 5 will quickly spray out high-pressure gas. These high-speed flowing gases act directly on the surface of the air duct body 3 with extremely high impact force, effectively peeling off the dust and impurities attached to it. The air duct body 3 itself is also rotating continuously. This exposes all surfaces of the air duct body 3 to the impact of high-pressure gas, thereby improving the uniformity and comprehensiveness of cleaning. Centrifugal force also helps to remove some loosened dust and impurities from the surface of the air duct body 3, further enhancing the cleaning effect. After the initial treatment of the surface of the air duct body 3, the control valve 12 is opened to connect the suction pipe. With the opening of the control valve 12, the dust and impurities cleaned by the high-pressure jet pipe 5 are quickly sucked in and collected through the suction pipe. This solves the problem that the cleaning effect is relatively limited when dealing with components with complex arc designs, such as central air conditioning ducts. The design of central air conditioning ducts often includes multiple curved and arc-shaped surfaces. These non-planar structures make it difficult for the suction power of the vacuum cleaner to be evenly distributed, thus affecting the cleaning effect on deep-seated dirt inside and on the surface of the central air conditioning duct.

[0023] 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.
