[0002] In many buildings, for the convenience of ventilation and heating, ventilation pipes are usually added in building floors to transport hot air or cold air. Among them, the annular ventilation pipe is the most widely used because of its stable structure, good fluidity and compact structure. However, with the use of the pipeline, a large amount of sundries such as dust, cobwebs and scale will accumulate in the pipeline, and the appearance of these sundries will greatly affect the ventilation effect. Therefore, during use, it is necessary to clean the inner wall of the pipeline regularly.
[0003] The traditional cleaning method for heating and ventilation pipelines is usually that workers insert a rod-shaped object into the pipeline to clean it, and the operation is relatively cumbersome. Therefore, corresponding improvements need to be made according to the above problems. Content of the Utility Model

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described 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 of 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.
[0017] According to Figure 1 - Figure 2 As shown, it includes a housing 1. A plurality of groups of heat dissipation holes 11 are opened at the position near the edge of one inner wall of the housing 1, and a suction fan 12 is installed at the position near the middle of one inner wall of the housing 1. The output end of the suction fan 12 is drivingly connected to a suction duct 13, and threaded holes 14 are opened at the positions near the top and bottom of the other end of the housing 1. A hand-held handle 15 is installed at the position near the bottom of the outer surface of the housing 1.
[0018] A dust collection hood 2 is movably arranged at a position near the other end inside the housing 1. A plurality of groups of air suction holes 21 are formed in the inner wall of one end of the dust collection hood 2. Mounting plates 22 are installed at positions near the top and bottom of the side surface of the dust collection hood 2. Bolts 23 are movably screwed inside the mounting plates 22. The outer diameter of one end of the bolt 23 is adapted to the inner diameter of the threaded hole 14. One end of the bolt 23 extends into the threaded hole 14 and is slidably connected thereto. Holding rods 24 are installed at positions near the front and rear sides of the side surface of the dust collection hood 2. An installation cylinder 25 is installed at a position near the middle of the inner wall of one end of the dust collection hood 2. An installation rod 26 is movably screwed inside the installation cylinder 25. Thread grooves are formed in the inner wall of the installation cylinder 25. Threads are provided on the outer surface of the installation rod 26 near one end of the installation cylinder 25, so that one end of the installation rod 26 is screwed and installed with the thread grooves formed in the inner wall of the installation cylinder 25 through the threads. An installation groove 27 is formed at a position near the end of the installation rod 26. An electric push rod 28 is installed on one inner wall of the installation groove 27. The inside of the housing 1 and the inside of the installation groove 27 are both open. One end of the electric push rod 28 is installed with an installation head 29. Four connecting rods 3 are installed on the side surface of the installation head 29. The four connecting rods 3 are centrosymmetrically arranged with the center point of the installation head 29 as the center. One end of each connecting rod 3 is installed with a scraping plate 31. Barbed cloth 32 is provided on the surface of each scraping plate 31.
[0019] When the staff uses this device to clean the HVAC ducts with dust, cobwebs and other sundries accumulated on the inner wall, first, one end of the housing 1 can be aligned with the pipe orifice of the HVAC duct through the hand-held handle 15, so that one end of the mounting rod 26, the four connecting rods 3, the four scraping plates 31 and the four barbed cloths 32 can extend into the interior of the HVAC duct accordingly, and the outer surfaces of the four barbed cloths 32 can be arranged in contact with the inner wall of the HVAC duct. Subsequently, the device is powered on, so that the suction fan 12 can operate normally. At this time, the arrangement of several heat dissipation holes 11 can dissipate the heat generated during the operation of the suction fan 12. Thus, under the action of the operation of the suction fan 12, the suction pipe 13 can perform the air suction operation, so that a pressure difference can be generated inside the duct, and thus a wind force in the direction of the housing 1 can be generated inside the duct. Under the action of the wind force, the dust, cobwebs and other sundries in the HVAC duct can be collected into the interior of the dust collection cover 2 and collected accordingly. The arrangement of several air suction holes 21 can enable the air flow inside the housing 1 to circulate normally. At the same time, the user can start the electric push rod 28. Thus, under the action of the operation of the electric push rod 28, the mounting head 29 can move deeper into the interior of the HVAC duct accordingly, so that the four connecting rods 3, the four scraping plates 31 and the four barbed cloths 32 can move accordingly, so that the four barbed cloths 32 can adhere to the dust, cobwebs and other sundries adhering to the inner wall of the HVAC duct, which is convenient for subsequent removal operations. When the sundries inside the HVAC duct are cleaned up, the user can move the entire device out of the interior of the HVAC duct. After that, the user can rotate the two bolts 23 accordingly, so that one ends of the two bolts 23 can move out of the corresponding threaded holes 14 respectively. Then, the dust collection cover 2 can be detached from the interior of the housing 1 through the two hand-held rods 24, so that the dust, cobwebs and other sundries inside the dust collection cover 2 can be cleaned accordingly. At the same time, the mounting rod 26 can be rotated accordingly, so that one end of the mounting rod 26 can be rotated out of the interior of the mounting cylinder 25. At this time, the sundries adhering to the four barbed cloths 32 can be cleaned accordingly. After the cleaning is completed, the user can perform the reverse operation according to the above operations to install between the mounting rod 26 and the mounting cylinder 25 and install between the dust collection cover 2 and the housing 1, which is convenient for subsequent continued use.
[0020] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
