At the same time, compressed air sprayed from the nozzle of the blowing ring blows the air filter placed inside the cylinder from bottom to top, thereby achieving the purpose of automatically cleaning the air filter and reducing the labor intensity of workers.

[0003] However, when the air filter cleaning device blows and cleans the air filter, the air filter is in a stationary state and cannot use the centrifugal force of the rotating air filter to achieve the purpose of removing dust. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a cylindrical air filter cleaning device that utilizes the centrifugal force of the rotating air filter to achieve dust removal, thereby improving the dust removal effect of the air filter.

[0005] To address the aforementioned problems, this utility model provides a cylindrical air filter cleaning device, comprising a cylindrical body, a cylindrical cover, a blow pipe, a tray, and a drive unit. The cylindrical cover is detachably connected to the cylindrical body and is used to seal the cylindrical body. The drive unit is disposed on the cylindrical body and is drivenly connected to the tray located inside the cylindrical body to drive the tray to rotate around the axial direction of the cylindrical body. The tray is used to fix the cylindrical air filter to be cleaned. The first end of the blow pipe is disposed on the cylindrical cover and is used to communicate with a compressed air source outside the cylindrical body. The second end of the blow pipe extends axially into the cylindrical body and is provided with a jet nozzle for blowing compressed gas toward the cylindrical air filter. The cylindrical body is also provided with an outlet for discharging the gas inside the cylindrical body.

[0006] Furthermore, the total length of the jet section along the axial direction of the cylinder is greater than or equal to the total length of the cylindrical air filter element.

[0007] Furthermore, the jet section is formed by multiple jet holes, with adjacent jet holes spaced apart along the axial direction of the cylinder, the distance between any two adjacent jet holes being 3mm, and the diameter of each jet hole being 3mm.

[0008] Furthermore, the jet section is formed by a jet groove, and the width of the jet groove is set to 3mm.

[0009] Furthermore, the cylinder includes a main body and a base. The two ends of the main body are open. One end of the main body is detachably and sealed to the base, and the other end of the main body is detachably and sealed to the cylinder cover. The base is provided with a receiving cavity located inside the cylinder. The drive unit is fixed inside the receiving cavity. The base is provided with a wire through-hole communicating with the receiving cavity. The power cord of the drive unit passes through the wire through-hole.

[0010] Furthermore, the air outlet is located at the bottom of the base or the main body of the cylinder.

[0011] Furthermore, a control switch located outside the cylinder is electrically connected to the power supply line of the drive unit.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. In use, the cylindrical air filter cleaning device of this utility model involves opening the cylinder cover, fixing the cylindrical air filter to be cleaned on the tray, closing the cylinder cover, and starting the drive unit. The drive unit drives the tray to rotate the cylindrical air filter around the axis of the cylinder. Simultaneously, compressed air is introduced into the blow pipe. The compressed air blows towards the cylindrical air filter through the jet nozzle, thus achieving the purpose of automatically cleaning the cylindrical air filter. In addition, the centrifugal force of the rotating cylindrical air filter helps to throw off the dust on the filter, thereby achieving the purpose of dust removal. In summary, the combination of the jet nozzle blowing on the rotating cylindrical air filter and the centrifugal force of the rotating filter can greatly improve the dust removal effect of the air filter.

[0029] Please refer to Figure 1 - Figure 6 This utility model provides a cylindrical air filter cleaning device; wherein, Figure 1 - Figure 4 This illustrates the cylindrical air filter cleaning device of this embodiment; Figure 5 - Figure 6 A schematic diagram illustrating the structure of the cylindrical air filter element 6 in this embodiment.

[0030] In this embodiment, the cartridge air filter cleaning device includes a cartridge body 1, a cartridge cover 2, a blow pipe 3, a tray 4, and a drive unit 5. The cartridge cover 2 is detachably connected to the cartridge body 1 and is used to seal the cartridge body 1. The drive unit 5 is disposed on the cartridge body 1 and is drivenly connected to the tray 4 located inside the cartridge body 1. The drive unit 5 drives the tray 4 to rotate around the axial direction of the cartridge body 1. The tray 4 is used to fix the cartridge air filter 6 to be cleaned. The first end of the blow pipe 3 is disposed on the cartridge cover 2 and is used to communicate with a compressed air source outside the cartridge body 1. The second end of the blow pipe 3 extends axially into the cartridge body 1 and is provided with a jet nozzle for blowing compressed gas toward the cartridge air filter 6. The cartridge body 1 is also provided with an outlet 102 for discharging the gas inside the cartridge body 1.

[0031] In this embodiment, the cartridge air filter cleaning device is used by opening the cartridge cover 2, fixing the cartridge air filter 6 to be cleaned on the tray 4, then closing the cartridge cover 2, and starting the drive unit 5. The drive unit 5 drives the tray 4 to rotate the cartridge air filter 6 around the axis of the cartridge body 1. At the same time, compressed air is introduced into the blow pipe 3. The compressed air blows towards the cartridge air filter 6 through the jet nozzle, thus achieving the purpose of automatically cleaning the cartridge air filter 6. In addition, the centrifugal force of the rotating cartridge air filter 6 helps to throw off the dust on the cartridge air filter 6. In summary, the combination of the jet nozzle blowing on the rotating cartridge air filter 6 and the centrifugal force of the rotating cartridge air filter 6 can greatly improve the dust removal effect of the air filter.

[0032] In one embodiment, the cartridge air filter 6 is fixed to the tray 4 by screws, specifically, referring to... Figure 4 - Figure 6 The screw passes through the central hole 60 at the bottom of the cartridge air filter 6 and is threaded into the central threaded hole 40 on the tray 4, thus fixing the cartridge air filter 6 onto the tray 4. The drive unit 5 is a drive motor, and the output shaft of the drive motor is coaxially connected to the tray 4, with the central threaded hole 40 being coaxially set with the tray 4.

[0033] It should be noted that after the cartridge air filter 6 is fixed on the tray 4, the blow pipe 3 can be set to be coaxial with the cartridge air filter 6 to avoid screw interference as the blow pipe 3 extends to the bottom of the cartridge air filter 6.

[0034] In one embodiment, the total length of the jet section in the axial direction of the cylinder 1 is greater than or equal to the total length of the cylindrical air filter element 6, so that the compressed gas blown out by the jet section covers the cylindrical air filter element 6 in the axial direction of the cylinder 1, thereby increasing the cleaning area of ​​the jet section on the cylindrical air filter element 6.

[0035] In one embodiment, reference is made to Figure 1 The jet section is formed by multiple jet holes 30, with adjacent jet holes 30 spaced apart along the axial direction of the cylinder 1. The distance between any two adjacent jet holes 30 is 3mm. The diameter of each jet hole is set to 3mm, but is not limited to this. The distance between any two adjacent jet holes is uniform, achieving a uniform purging effect. Of course, in other embodiments, the diameter of the jet holes can be reasonably changed according to the specifications of the cylindrical air filter element 6. In addition, refer to... Figure 2 In other embodiments, the jet section may also have a jet groove 31 extending axially along the cylinder 1, and the width of the jet groove 31 is set to 3 mm, but is not limited thereto.

[0036] In one embodiment, the cover 2 is provided with an air inlet 101, the outlet end of the air inlet 101 is connected to the first end of the blowpipe 3, and the first end of the blowpipe 3 is connected to the outlet of the air inlet 101, so that the blowpipe 3 can be removed from the cover 2, which is convenient for replacing the blowpipe 3. In addition, the second end of the blowpipe 3 can be located inside the cylindrical air filter 6 fixed on the tray 4, or it can be located outside the cylindrical air filter 6 fixed on the tray 4, which is not limited here. For example, when it is necessary to back-blow the outside of the cylindrical air filter 6, the second end of the blowpipe 3 can be located inside the cylindrical air filter 6; when it is necessary to forward-blow the outside of the cylindrical air filter 6, the second end of the blowpipe 3 can be located outside the cylindrical air filter 6. It can be seen that the cylindrical air filter cleaning device of this embodiment can perform forward and reverse blowing operations on the cylindrical air filter 6.

[0037] It should be noted that blowing air from the inner cavity of the cartridge air filter 6 is generally understood as "backblowing." In normal use, the cartridge air filter 6 is designed to allow air to flow in from the outside (i.e., the windward side or front) of the filter element and flow through the filter media inside to the inner cavity (i.e., the leeward side or back), thereby filtering out impurities and particles in the air. When air is blown from the inner cavity of the cartridge air filter 6, the direction of airflow is opposite to that during normal operation, hence the term "backblowing."

[0038] However, the patent (publication number: CN221771787U) discloses an air filter cleaning device, in which the blowing ring blows air from the outside of the cylindrical air filter 6, which is obviously a "forward blowing" operation. Moreover, the cylindrical air filter 6 cannot be placed outside the outer ring of the blowing ring. That is, the existing air filter cleaning device cannot achieve the "back-blowing" operation of the cylindrical air filter 6, resulting in a significantly less effective cleaning effect on the cylindrical air filter 6 than the cylindrical air filter cleaning device of this embodiment.

[0039] In one embodiment, the cylinder 1 includes a cylinder body 10 and a base 11. The cylinder body 10 has open ends at both ends. One end of the cylinder body 10 is detachably and sealingly connected to the base 11, and the other end is detachably and sealingly connected to a cylinder cover 2. The cylinder cover 2 is a conical sealing cover, and a sealing ring can be used to seal between the cylinder cover 2 and the cylinder body 10, as well as between the cylinder body 10 and the base 11. Furthermore, the detachable connection between the cylinder cover 2 and the cylinder body 10, and the detachable connection between the cylinder body 10 and the base 11, uses existing detachable connection structures, which will not be elaborated here. The detachable connection between the cylinder body 10 and the base 11 facilitates fixing the drive unit 5 to the base 11, and the detachable connection between the cylinder body 10 and the cylinder cover 2 facilitates fixing the cylindrical air filter element 6 to be cleaned to the tray 4. In addition, a receiving cavity 110 located inside the cylinder 1 is provided on the base 11, and the drive unit 5 is fixed inside the receiving cavity 110. A wire through hole 111 communicating with the receiving cavity 110 is provided on the base 11 of the receiving cavity 110, and the power line 50 of the drive unit 5 passes out from the wire through hole 111.

[0040] In one embodiment, a control switch 7 located outside the cylinder 1 is electrically connected to the power line 50 of the drive unit 5. The control switch 7 is used to control the working state of the drive unit 5, which facilitates the use of the cartridge air filter cleaning device.

[0041] In one embodiment, the receiving cavity 110 is a conical cavity with an inner diameter that gradually decreases from top to bottom. The air outlet 102 can be located at the bottom of the base 11 and communicates with the conical cavity. The conical cavity allows dust from the main body 10 to enter the bottom of the main body 1, so that dust falling from the cartridge air filter 6 is discharged from the air outlet along the air outlet direction. To avoid dust generation, a dust collection bag 8 is connected to the air outlet end to collect the dust discharged from the air outlet 1, achieving a clean and environmentally friendly effect.

[0042] In summary, the cartridge air filter cleaning device of this embodiment cleans the cartridge air filter 6 entirely in a closed space, which is clean and environmentally friendly and avoids dust generation.

[0043] In other embodiments, the air outlet can also be located at the bottom of the cylinder body 10, so that dust falling from the cylinder air filter 6 can also be discharged from the air outlet along the air outlet direction.

[0044] In one embodiment, a pressure gauge 9 is provided on the air inlet 101. The air inlet 101 is used to connect to a compressed air source. The pressure gauge 9 can detect the pressure entering the blow pipe 3 in real time. By observing the air inlet pressure, the blow quality can be ensured.

[0045] In one embodiment, a bracket (not shown) may also be fixed to the bottom of the base 11, and the bracket is provided with casters (not shown), which facilitates the handling of the cartridge air filter cleaning device.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
