Description

Technical Field

[0001] The utility model relates to the technical field of primary filter plates for kitchen oil fume purifiers, and more specifically, to a primary filter structure for an integrated oil fume purifier. Background Art

[0002] The primary filter screen plate of a kitchen oil fume purifier is used to filter impurities in the oil fume. The filter screen plate contains a fixed frame and a filter screen. The fixed frame and the filter screen are fixedly connected. The filter screen can filter some impurities in the oil fume to meet people's needs. With the continuous development of technology, people's requirements for the manufacturing process of the primary filter screen plate of kitchen oil fume purifiers are also getting higher and higher.

[0003] The existing patent CN215462778U discloses a primary filter screen plate for a kitchen oil fume purifier. To achieve the above object, the technical solution adopted by the present utility model is: a primary filter screen plate for a kitchen oil fume purifier, including a filter screen plate frame, the inner surface of the filter screen plate frame is fixedly connected with a filter screen, a chute is provided on the front outer surface of the filter screen plate frame, an installation mechanism is slidably connected to the inner surface of the chute, and an anti-sticking layer is coated on the outer surface of the filter screen; the upper end of the installation mechanism is fixedly connected with a positioning rod, the outer surface of the positioning rod is fixedly connected with an annular connecting plate, a grip rod and an annular positioning plate, the grip rod is located at one end of the annular connecting plate, the annular positioning plate is located outside the grip rod, a spring is fixedly connected to the outer surface of the other end of the annular connecting plate, and an anti-slip pad is fixedly connected to the outer surface of one end of the annular positioning plate.

[0004] However, the above integrated oil fume purifier uses an iron plate punching as the first layer of filter screen in the purification box. This structure has a very large air inlet resistance coefficient. After a long time of use, the hole diameters adhered by oil stains become smaller, and the air intake volume drops severely. Even for some other filter structures, in some environments of open-fire charcoal grilling, small particle sparks may even be sucked into the working electric field, increasing the possibility of fire. The cleaning frequency is relatively high, and it is not convenient to remove the baffle for cleaning. The outer baffle requires tools such as a screwdriver, and the operation is relatively cumbersome. Removing the screws for a long time is easy to damage. Summary of the Utility Model

[0005] In view of this, the present utility model provides a primary filter structure for an integrated oil fume purifier, which solves the problems of large air resistance of the traditional hole plate and the large oil particles that can directly pass through the holes.

[0006] To achieve the above object, the present utility model provides the following technical solution: a primary filter structure for an integrated oil fume purifier, the filter structure is installed in the integrated oil fume purifier, and the filter structure includes a filter screen plate and a slot structure for placing the filter screen plate;

[0007] The filter screen plate is composed of a frame and a wire mesh. A frame-shaped border is provided, with a diamond-woven wire mesh embedded therein, and a pull handle is drawn on the side of the border.

[0008] The slot structure is arranged on the bottom plate of the box body and is a vertical groove structure. Z-shaped side plates are symmetrically arranged at the ends of the groove structure for restricting the filter screen plate and installing the cover. U-shaped grooves are welded up and down at the bottom of the groove structure for the track of the filter screen plate.

[0009] Preferably, in the above primary filtration structure, the cover and the Z-shaped side plate are of an insertion structure, inserted from top to bottom. The thickness of the side of the cover corresponds to the thickness of the Z-shaped side plate, and a buckle is arranged at the bottom of the cover.

[0010] Preferably, in the above primary filtration structure, the buckle on the cover is higher than the bottom plate of the box body, and both ends of the buckle are higher than the part of the buckle.

[0011] Preferably, in the above primary filtration structure, the wire mesh is made of 304 material, and several layers of wire mesh are arranged.

[0012] Through the above technical solutions, compared with the prior art, the present utility model discloses a primary filtration structure for an oil fume purification integrated machine, which changes the traditional punching plate to a structure of multiple layers of 304 material wire meshes, and is fixed with diamond-shaped hole meshes, greatly reducing the wind resistance coefficient, while blocking some large oil fume particles, prolonging the service life of the purification electric field and extending the cleaning time; further, the outer cover baffle is changed to a pull-up structure, which is convenient to take.
