Description

Technical Field

[0001] This utility model belongs to the field of air filter technology, and more specifically, it relates to an air filter purification device that can automatically clean itself. Background Technology

[0002] An automatically cleanable air filter purification device is a high-efficiency air purification device that combines intelligent control and physical cleaning technology. Its core advantage lies in extending the life of the filter element through automated maintenance and reducing manual intervention. When cleaning the air filter element, existing methods generally clean the air filter element through mechanical vibration, using a motor to drive an eccentric wheel or an ultrasonic generator to generate high-frequency vibration, causing dust to fall off the surface of the filter element.

[0003] The existing application number is CN202321290445.9. This utility model discloses a self-cleaning air filter element, including: a mounting plate and a plug-in mechanism. A filter screen is fixedly installed on the mounting plate, and a reciprocating screw is rotatably connected to the mounting plate. A drive motor is installed on the top wall of the mounting plate, and the output end of the drive motor is connected to the reciprocating screw. A moving rod is threadedly connected to the reciprocating screw, and both plug-in mechanisms are set on the moving rod. In the process of use, when installing the cleaning brush, the pressure plate can be pulled outward by pulling the pull block, so that the pressure plate slides outward on the two support rods and compresses the first spring. When the pressure plate slides to the desired position, the mounting seat is placed in the mounting groove. Releasing the pull block, the compressed first spring returns to its original position, causing the pressure plate to press against the moving rod and causing the two plug-in rods to be inserted into the plug-in groove, thereby fixing the mounting seat in the mounting groove and realizing the installation of the cleaning brush. The operation is simple and convenient, and it is easy to clean the cleaning brush regularly.

[0004] Based on the above, when cleaning the air filter, although the dust on the surface of the air filter is shaken off, the shaken-off dust still remains inside the filter housing. This causes the dust in the housing to easily re-adhere to the surface of the air filter when the purifier is used next time, affecting the cleaning effect of the air filter. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an automatically cleaning air filter purification device. This solves the problem that, in existing air filter cleaning systems, although dust on the surface of the air filter is shaken off, the shaken-off dust still remains inside the filter housing. As a result, when the purifier is used again, the dust in the housing easily re-adheres to the surface of the air filter, affecting the cleaning effect.

[0006] The purpose and effectiveness of this self-cleaning air filter purification device are achieved through the following specific technical means:

[0007] An automatically cleanable air filter purification device includes a filter mounting housing, an air filter body, a collection connector, a cleaning drive box, a pulse connecting pipe, a pulse cleaning mechanism, and a cleaning collection mechanism. The air filter body is fixedly connected inside the filter mounting housing. Two sets of collection connectors are provided, each fixedly connected to the bottom of the filter mounting housing and positioned on the front and rear sides of the air filter body. The cleaning drive box is fixedly connected to the left side of the filter mounting housing. The pulse connecting pipe is fixedly connected to the bottom of the cleaning drive box and connected to a compressed air tank. The pulse cleaning mechanism is located on the outside of the filter mounting housing. The cleaning collection mechanism is located below the filter mounting housing.

[0008] Furthermore, the pulse cleaning mechanism includes a pressure sensor and a pulse controller; two sets of pressure sensors are provided, which are fixedly connected to the upper part of the filter mounting box and respectively located on the front and rear sides of the air filter body; the pulse controller is fixedly connected to the left side of the filter mounting box, and the pulse controller and the two sets of pressure sensors form the core interactive link of the closed-loop control system, and the pulse controller is electrically connected to the solenoid valve of the external compressed air tank.

[0009] Furthermore, the pulse cleaning mechanism also includes a cleaning drive tube and a cleaning connecting tube; the cleaning drive tube is a venturi tube structure and is fixedly connected to the top of the cleaning drive box; the cleaning connecting tube is fixedly connected to the upper end of the cleaning drive tube, and the upper end of the cleaning connecting tube is inserted into the inner side of the air filter body.

[0010] Furthermore, the cleaning and collection mechanism includes a collection drive wheel; the collection drive wheel is rotatably connected inside the cleaning drive box.

[0011] Furthermore, the cleaning and collection mechanism also includes: a collection drive roller, a first collection gear, and a second collection gear; two sets of collection drive rollers are provided, and the two sets of collection drive rollers are rotatably connected to the inner side of the collection connector, and multiple sets of semi-cylindrical groove structures are opened on the outer periphery of the two sets of collection drive rollers; two sets of first collection gears are provided, and the two sets of first collection gears are coaxially fixedly connected to the left side of the collection drive roller; two sets of second collection gears are provided, and the two sets of second collection gears are rotatably connected to the front and rear sides of the cleaning drive box, and the two sets of second collection gears are coaxially fixedly connected to the collection drive wheel.

[0012] Furthermore, the cleaning and collection mechanism also includes a collection box; two sets of collection boxes are provided, and the two sets of collection boxes are respectively inserted into the lower part of the cleaning drive box, and the upper end of the two sets of collection boxes is provided with an opening structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a pulse cleaning mechanism. When two sets of pressure sensors detect that the pressure difference between the front and rear sides of the air filter body exceeds a threshold, the pulse controller receives a signal and controls the solenoid valve of the compressed air tank to open. High-pressure gas enters the cleaning drive box through the pulse connecting pipe and then enters the cleaning drive tube. The cleaning drive tube repressurizes the high-pressure gas, and the compressed gas enters the air filter body through the cleaning connecting pipe, achieving a pulse dust removal effect on the air filter body. This avoids the need for users to manually clean the air filter body and facilitates automatic cleaning of the air filter body.

[0015] This invention features a cleaning and collection mechanism. The collection drive wheel is blown to rotate, which in turn drives the second collection gear to rotate. The second collection gear then drives the first collection gear to rotate, which in turn drives the collection drive roller to rotate. The rotating collection drive roller transports the blown-off dust into the collection box, which collects the dust, preventing it from re-adhering and improving the cleaning effect on the air filter body.
