Description

Technical Field

[0001] This application relates to the field of filter cartridges, and more particularly to a dustproof assembly for filter cartridges. Background Technology

[0002] An air filter is an air filtration device, generally used in clean workshops, clean factories, laboratories, and clean rooms, or for dust prevention in electronic, mechanical, and communication equipment. An air filter element is a type of filter primarily used to filter the air entering the engine, preventing dust, particulate matter, and other impurities from entering the cylinders, thus protecting the engine's normal operation. It is typically installed at the engine's air intake, such as in front of the carburetor or intake manifold. The air filter element effectively blocks dust, particulate matter, and other impurities in the air, ensuring clean air entering the engine, preventing piston assembly and cylinder wear, and preventing "cylinder scoring." By filtering impurities from the air, the air filter element can reduce engine wear and extend its service life. During installation, a conventional filter element is installed in the required position, and a rubber sealing ring is installed on the surface of the filter element body. The sealing ring effectively improves the seal between the filter element body and the connection point. A baffle is installed at one end of the filter element body to block larger impurities.

[0003] Regarding the aforementioned technologies, the inventors believe that since the filter element's shield is mostly installed near the external environment, after prolonged use, the surface of the shield is prone to blockage due to dust and cobwebs, which can obstruct the airflow of the filter element. This requires regular cleaning by staff, causing inconvenience when using the filter element.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0011] Preferably, a limiting block is fixedly installed on the inner wall of the connecting box. The dimensions of the limiting block surface are adapted to the dimensions of the pushing block surface. An auxiliary piece is fixedly connected to one end of the limiting block. The auxiliary piece is a rubber sheet, and the dimensions of the auxiliary piece surface are adapted to the dimensions of the limiting block surface.

[0012] Preferably, a shielding strip is fixedly connected to the surface of the shielding plate.

[0013] Preferably, an electric control valve is fixedly connected to the surface of the water inlet pipe, and the electric control valve is vertically positioned between the water inlet pipe and the water inlet pipe.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By installing a connecting box and drain pipe on the surface of the filter frame, with one end of the connecting box connected to a water inlet pipe to introduce water into the filter frame and remove impurities and dust, a baffle plate is slidably installed on the inner wall of the connecting box to prevent water from entering the filter element. A push block is installed at one end of the baffle plate, and a water inlet chamber is installed on the surface of the connecting box to control the push block to move to the position of the water inlet chamber, connecting the baffle plate to the filter frame.
