Description

Technical Field

[0001] This invention belongs to the field of ventilation duct cleaning technology, specifically a ventilation duct surface cleaning and decontamination device. Background Technology

[0002] Ventilation ducts are a type of municipal infrastructure used to facilitate the circulation of indoor and outdoor air and reduce the concentration of harmful gases in indoor air.

[0003] Currently, ventilation ducts are often clogged with dust and other debris due to the presence of air inside. This dust and debris adheres to the inner walls of the ducts, which can easily cause blockages and breed bacteria. These bacteria can then enter the room with the subsequent airflow, threatening the physical and mental health of people inside. Therefore, it is necessary to clean and remove dirt from the inner walls of ventilation ducts regularly.

[0004] In existing technologies, most cleaning robots clean the inner walls of ventilation ducts by walking along them. However, most existing cleaning robots move by rolling along the inner walls of ventilation ducts using wheels. Since the inner walls of ventilation ducts contain dust and debris, the frictional resistance between the wheels and the inner walls is small, making it difficult to move and thus affecting the cleaning effect of the inner walls of ventilation ducts. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a device for cleaning and removing dirt from the surface of ventilation ducts.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A surface cleaning and decontamination device for ventilation ducts includes a first flexible decontamination component, an air injection component, a drive component, and a second flexible decontamination component.

[0008] The first flexible decontamination component and the second flexible decontamination component are distributed at intervals.

[0009] The drive component is disposed between the first flexible cleaning component and the second flexible cleaning component, and is used to drive the first flexible cleaning component and the second flexible cleaning component to move alternately along the interior of the ventilation duct.

[0010] One end of the air injection component is connected to the first flexible decontamination component, and the other end is connected to the second flexible decontamination component.

[0011] As the first flexible cleaning component travels along the interior of the ventilation duct, the air injection component injects air into the second flexible cleaning component, causing it to expand and press against the inner wall of the ventilation duct, thereby providing support for the movement of the first flexible cleaning component.

[0012] As the second flexible cleaning component travels along the interior of the ventilation duct, the air injection component injects air into the interior of the first flexible cleaning component to cause the first flexible cleaning component to expand and abut against the inner wall of the ventilation duct, thereby providing support for the movement of the second flexible cleaning component.

[0013] As a further improvement of the present invention: the first flexible decontamination component includes a first support plate and a first flexible layer circumferentially disposed on the outer wall of the first support plate.

[0014] The second flexible decontamination assembly includes a second support plate and a second flexible layer circumferentially disposed on the outer wall of the second support plate.

[0015] A support pipe is fixedly installed on one side of the second support plate. The end of the support pipe away from the second support plate passes through the first support plate and is connected to an end block. The end block is connected to the first support plate by a second elastic element.

[0016] The drive assembly includes a motor, an incomplete gear, and a second rack.

[0017] A support plate is fixedly installed on one side of the first support plate, the motor is installed on one side of the support plate, the incomplete gear is connected to the output end of the motor through a rotating shaft, and the second rack is installed on the side wall of the support pipe and can mesh with the incomplete gear.

[0018] As a further improvement of the present invention: a first air pipe is provided on one side of the first support plate.

[0019] A second air pipe is provided on one side of the second support plate. One end of the first air pipe is connected to the inner side of the first flexible layer, and the other end is connected to the second air pipe through a flexible air pipe.

[0020] The end of the second air tube away from the flexible air tube is connected to the inner side of the second flexible layer, and the air injection component is installed on the first air tube and can reciprocate along the length of the first air tube.

[0021] As a further improvement of the present invention: the gas injection assembly includes a plunger rod, a first rack, and a first elastic element.

[0022] The plunger rod is movably disposed inside the first trachea. A groove is formed along the length of the side wall of the first trachea. A connecting rod is fixedly disposed on one side of the plunger rod. The end of the connecting rod away from the plunger rod extends from the groove to the outside of the first trachea and is connected to the first rack.

[0023] One end of the first elastic element is connected to the first support plate, and the other end is connected to the first rack, which is used to provide elastic tension to the first rack.

[0024] As a further improvement of the present invention: the first elastic element and the second elastic element are springs or metal sheets.

[0025] As a further improvement of the present invention: the first flexible layer and the second flexible layer are rubber layers or silicone layers.

[0026] As a further improvement of the present invention: one end of the support pipe is also connected to a liquid inlet pipe, the end of the liquid inlet pipe away from the support pipe extends to the outside of the ventilation pipe and is connected to a container containing cleaning liquid via a water pump, and several nozzles are also provided on the side wall of the support pipe.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] In this embodiment of the invention, when it is necessary to clean and remove contaminants from the inner wall of the ventilation duct, a first flexible cleaning component and a second flexible cleaning component can be placed together inside the ventilation duct. A driving component then moves the first and second flexible cleaning components alternately within the ventilation duct, thereby cleaning the debris adhering to the inner wall of the ventilation duct. As the first flexible cleaning component moves along the inside of the ventilation duct, an air injection component injects air into the second flexible cleaning component, causing the second flexible cleaning component to expand and press against the inner wall of the ventilation duct, thus providing support for the movement of the first flexible cleaning component and improving the efficiency of the cleaning process. The first flexible cleaning component effectively removes debris from the inner wall of a ventilation duct. As the second flexible cleaning component moves along the duct, an air injection component injects air into the first flexible cleaning component, causing it to expand and press against the inner wall of the duct. This provides support for the movement of the second flexible cleaning component, improving its cleaning effect on the duct's inner wall. Compared to existing technologies, by using two sets of flexible cleaning components, along with a drive component and an air injection component, the two sets of flexible cleaning components move stably and alternately along the duct, thus improving the cleaning effect on the duct's inner wall.

Detailed Implementation

[0034] The technical solution of this application will be further described in detail below with reference to specific embodiments.

[0035] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0036] Please see Figure 1This embodiment provides a ventilation duct surface cleaning and decontamination device, including a first flexible decontamination component 10, an air injection component 20, a drive component 30, and a second flexible decontamination component 50. The first flexible decontamination component 10 and the second flexible decontamination component 50 are spaced apart. The drive component 30 is disposed between the first flexible decontamination component 10 and the second flexible decontamination component 50, and is used to drive the first flexible decontamination component 10 and the second flexible decontamination component 50 to move alternately along the interior of the ventilation duct. One end of the air injection component 20 is connected to the first flexible decontamination component 10, and the other end is connected to the second flexible decontamination component 50. When the first flexible cleaning component 10 travels along the interior of the ventilation duct, the air injection component 20 injects air into the interior of the second flexible cleaning component 50 to cause the second flexible cleaning component 50 to expand and abut against the inner wall of the ventilation duct, thereby providing support for the travel of the first flexible cleaning component 10.

[0037] When cleaning and decontamination of the inner wall of the ventilation duct is required, the first flexible decontamination component 10 and the second flexible decontamination component 50 can be placed together inside the ventilation duct. Then, the drive component 30 drives the first flexible decontamination component 10 and the second flexible decontamination component 50 to move alternately inside the ventilation duct, thereby cleaning the debris attached to the inner wall of the ventilation duct. When the first flexible decontamination component 10 moves along the inside of the ventilation duct, the air injection component 20 injects air into the second flexible decontamination component 50, causing the second flexible decontamination component 50 to expand. The first flexible cleaning component 10 is placed against the inner wall of the ventilation duct, thereby providing support for its movement and improving its cleaning effect on the inner wall of the ventilation duct. When the second flexible cleaning component 50 moves along the inside of the ventilation duct, air is injected into the first flexible cleaning component 10 using the air injection component 20, causing the first flexible cleaning component 10 to expand and place against the inner wall of the ventilation duct, thereby providing support for its movement and improving its cleaning effect on the inner wall of the ventilation duct.

[0038] Please see Figure 1 and Figure 2In one embodiment, the first flexible cleaning component 10 includes a first support plate 101 and a first flexible layer 102 surrounding the outer wall of the first support plate 101. The second flexible cleaning component 50 includes a second support plate 501 and a second flexible layer 502 surrounding the outer wall of the second support plate 501. A support pipe 504 is fixedly disposed on one side of the second support plate 501. One end of the support pipe 504 away from the second support plate 501 passes through the first support plate 101 and is connected to an end block 507. The end block 507 is connected to the first support plate 101 through a second elastic member 506. The drive component 30 includes a motor (not shown in the figure), an incomplete gear 302, and a second rack 303. A support plate 104 is fixedly disposed on one side of the first support plate 101. The motor is mounted on one side of the support plate 104. The incomplete gear 302 is connected to the output end of the motor through a rotating shaft 301. The second rack 303 is mounted on the side wall of the support pipe 504 and can mesh with the incomplete gear 302.

[0039] The motor drives the rotating shaft 301 to rotate, which in turn drives the incomplete gear 302 to rotate. When the incomplete gear 302 meshes with the second rack 303, it can drive the support pipe 504 to move relative to the first support plate 101. The second elastic element 506 is stretched by force. When the support pipe 504 moves relative to the first support plate 101, it can drive the second support plate 501 to move towards the first support plate 101. The second flexible layer 502 on the outside of the second support plate 501 is attached to the inner wall of the ventilation pipe to scrape away the debris on the inner wall of the ventilation pipe and clean the inner wall of the ventilation pipe. During the above process, the air injection component 20 injects air into the first flexible layer 102 to drive the first flexible layer 102 to expand, thereby tightening the inner wall of the ventilation pipe to enhance the stability of the first support plate 101 inside the ventilation pipe and provide support for the movement of the second support plate 501 and the second flexible layer 502. When the incomplete gear 302 disengages from the second rack 303, the air injection component 20 injects air into the second flexible layer 502, causing the second flexible layer 502 to expand and tighten the inner wall of the ventilation duct, thus confining the second support plate 501 inside the ventilation duct. At this time, the pulling action of the second elastic element 506 drives the first support plate 101 to move away from the second support plate 501, and the first flexible layer 102 moves synchronously with the first support plate 101 to scrape away debris from the inner wall of the ventilation duct, thus cleaning the inner wall of the ventilation duct. When the incomplete gear 302 re-engages with the second rack 303, the air injection operation of the air injection component 20 into the first flexible layer 102 allows the second support plate 501 and the second flexible layer 502 to move again. This cycle repeats, allowing the first support plate 101 and the second support plate 501 to move alternately inside the ventilation duct.

[0040] Please see Figure 1 and Figure 2 In one embodiment, a first air pipe 103 is provided on one side of the first support plate 101, and a second air pipe 503 is provided on one side of the second support plate 501. One end of the first air pipe 103 is connected to the inner side of the first flexible layer 102, and the other end is connected to the second air pipe 503 through a flexible air pipe 40. The end of the second air pipe 503 away from the flexible air pipe 40 is connected to the inner side of the second flexible layer 502. The air injection component 20 is installed on the first air pipe 103 and can reciprocate along the length direction of the first air pipe 103.

[0041] When the incomplete gear 302 meshes with the second rack 303 to drive the second support plate 501 to move towards the first support plate 101, the air injection component 20 moves along the length of the first air pipe 103, thereby compressing the air inside the first air pipe 103 to the inside of the first flexible layer 102 and drawing the air inside the second flexible layer 502 from the second air pipe 503 and the flexible air pipe 40 into the first air pipe 103. This causes the first flexible layer 102 to expand and the second flexible layer 502 to collapse. When the first flexible layer 102 expands, it can tighten and limit the first support plate 101, thereby providing stable support for the movement of the second support plate 501 and the support pipe 504. When the second flexible layer 502 collapses, it can appropriately reduce the tension on the inner wall of the ventilation pipe, so that the second flexible layer 502 can smoothly follow the second support plate 501 to achieve... The debris inside the ventilation duct is successfully scraped away. When the incomplete gear 302 and the second rack 303 are about to disengage, the air injection component 20 moves in the opposite direction along the length of the first air pipe 103 to draw air from the inside of the first flexible layer 102 into the inside of the first air pipe 103 and to pressurize the air inside the first air pipe 103 from the flexible air pipe 40 and the second air pipe 503 to the inside of the second flexible layer 502. This causes the first flexible layer 102 to collapse and the second flexible layer 502 to expand. When the second flexible layer 502 expands, it can tighten and limit the second support plate 501, thereby providing stable support for the movement of the first support plate 101. When the first flexible layer 102 collapses, it can appropriately reduce the tension on the inner wall of the ventilation duct so that the first flexible layer 102 can move smoothly with the first support plate 101, thus achieving the smooth scraping of debris from the inner wall of the ventilation duct.

[0042] Please see Figure 3 and Figure 4In one embodiment, the air injection assembly 20 includes a plunger rod 201, a first rack 203, and a first elastic element 204. The plunger rod 201 is movably disposed inside the first air pipe 103. A groove 105 is formed on the side wall of the first air pipe 103 along its length. A connecting rod 202 is fixedly disposed on one side of the plunger rod 201. One end of the connecting rod 202 away from the plunger rod 201 extends from the groove 105 to the outside of the first air pipe 103 and is connected to the first rack 203. One end of the first elastic element 204 is connected to the first support plate 101, and the other end is connected to the first rack 203, for providing elastic tension to the first rack 203.

[0043] When the incomplete gear 302 is about to disengage from the second rack 303, the incomplete gear 302 can engage with the first rack 203. At this time, the incomplete gear 302 can drive the first rack 203 to move, and the first elastic element 204 is stretched. When the first rack 203 moves, it can drive the plunger rod 201 to move along the inside of the first air pipe 103 through the connecting rod 202, so as to draw the air inside the first flexible layer 102 into the first air pipe 103 and empty the inside of the first air pipe 103. Air is compressed from the flexible air tube 40 and the second air tube 503 into the interior of the second flexible layer 502. When the air inside the first flexible layer 102 is drawn out, the tensioning effect of the first flexible layer 102 on the inner wall of the ventilation duct is reduced. After the incomplete gear 302 disengages from the second rack 303, the second elastic element 506 pulls the first support plate 101 to move away from the second support plate 501. When air is injected into the interior of the second flexible layer 502 and it expands, the second flexible layer 502... 2. The tensioning effect on the inner wall of the ventilation duct is enhanced to constrain the second support plate 501. When the incomplete gear 302 disengages from the first rack 203, the first elastic element 204 pulls the first rack 203 to move in the opposite direction, thereby driving the plunger rod 201 to move in the opposite direction inside the first air pipe 103, so as to compress the air inside the first air pipe 103 into the first flexible layer 102 and draw the air inside the second flexible layer 502 from the second air pipe 503 and the flexible air pipe 40 into the first air pipe 103. When the air inside the second flexible layer 502 is drawn out, the tensioning effect of the second flexible layer 502 on the inner wall of the ventilation duct is reduced. When the incomplete gear 302 engages with the second rack 303 thereafter, it is convenient to smoothly drive the second support plate 501 to move towards the first support plate 101. When air is injected into the first flexible layer 102 and expands, the tensioning effect of the first flexible layer 102 on the inner wall of the ventilation duct is enhanced to constrain the first support plate 101.

[0044] In one embodiment, the first elastic element 204 and the second elastic element 506 can be springs or metal sheets, and there is no limitation here.

[0045] In one embodiment, the first flexible layer 102 and the second flexible layer 502 may be rubber layers or silicone layers, and there is no limitation here.

[0046] Please see Figure 1 and Figure 2 In one embodiment, one end of the support pipe 504 is also connected to a liquid inlet pipe 60. The end of the liquid inlet pipe 60 away from the support pipe 504 extends to the outside of the ventilation pipe and is connected to a container containing cleaning fluid via a water pump. A plurality of nozzles 505 are also provided on the side wall of the support pipe 504.

[0047] As the first support plate 101 and the second support plate 501 move alternately inside the ventilation duct, the cleaning solution in the container can be pumped into the inlet pipe 60 by a water pump, and then enter the support pipe 504 through the inlet pipe 60. It is then output to the inner wall of the ventilation duct through several nozzles 505 to clean the inner wall of the ventilation duct. Combined with the scraping action of the first flexible layer 102 and the second flexible layer 502 on the inner wall of the ventilation duct, the cleaning and decontamination effect is improved.

[0048] In this embodiment of the invention, when it is necessary to clean and remove contaminants from the inner wall of the ventilation duct, the first flexible cleaning component 10 and the second flexible cleaning component 50 can be placed together inside the ventilation duct. Then, the driving component 30 drives the first flexible cleaning component 10 and the second flexible cleaning component 50 to move alternately inside the ventilation duct, thereby cleaning the debris attached to the inner wall of the ventilation duct. When the first flexible cleaning component 10 moves along the inside of the ventilation duct, air is injected into the second flexible cleaning component 50 using the air injection component 20, causing the second flexible cleaning component 50 to expand and abut against the inner wall of the ventilation duct, thereby providing support for the movement of the first flexible cleaning component 10 and improving its efficiency. The first flexible cleaning component 10 effectively cleans debris from the inner wall of the ventilation duct. When the second flexible cleaning component 50 moves along the inside of the ventilation duct, air is injected into the first flexible cleaning component 10 using the air injection component 20. This causes the first flexible cleaning component 10 to expand and press against the inner wall of the ventilation duct, thereby providing support for the movement of the second flexible cleaning component 50 and improving its cleaning effect on the inner wall of the ventilation duct. Compared with the prior art, by setting up two sets of flexible cleaning components and cooperating with the drive component 30 and the air injection component 20 to drive the two sets of flexible cleaning components to move stably and alternately along the inside of the ventilation duct, the cleaning effect on the inner wall of the ventilation duct is improved.

[0049] The preferred embodiments of this application have been described in detail above, but this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
