Description
Technical Field
[0001] The utility model belongs to the technical field of air filter elements, in particular to a dust removal air filter element. Background Art
[0002] An air filter is a device used to remove particulate impurities from the air, providing clean air for mechanical equipment to prevent the mechanical equipment from inhaling air containing impurity particles during operation, thereby increasing the probability of abrasion and damage. Traditional air filters are made of filter paper and rubber edge guards.
[0003] However, every time the air filter of a car is replaced, the filter paper and the rubber edge guard are replaced together, because the current air filter and rubber edge guard are integrated, the cost is high, and it is not environmentally friendly.
[0004] In view of this, the present utility model is proposed. Utility Model Content
[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:
[0006] The dust removal air filter element comprises an upper edge guard and a lower edge guard, which are covered on the bottom of the upper edge guard; the air filter paper is sealed and clamped between the upper edge guard and the lower edge guard; an overlapping boss is integrally provided on the outer edge of the upper edge guard; and reinforcing ribs are embedded in the overlapping boss; the upper edge guard and the lower edge guard are tightly connected to each other through a clamping assembly. During the actual installation process, when the air filter paper needs to be replaced, the upper edge guard and the lower edge guard can be directly separated, and then the air filter paper can be taken out, which is very convenient and ensures that the filter paper can be replaced separately each time the air filter element is replaced, which is more energy-saving and environmentally friendly.
[0007] As a preferred embodiment of the utility model, the snap-on assembly includes a paper buckle strip integrally installed at the bottom of the upper edge guard; and also includes a paper buckle groove opened on the lower edge guard, and the paper buckle strip is vertically aligned and snap-on with the paper buckle groove.
[0008] As a preferred embodiment of the present utility model, the lower end of the loop buckle strip is arrow-shaped.
[0009] As a preferred embodiment of the present invention, the reinforcing ribs extend into the upper edge guard.
[0010] As a preferred embodiment of the utility model, the inner cavity edge on one side where the upper guard and the lower guard face each other is provided with a "V"-shaped sealing groove for fitting the folded corner of the air filter paper.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] In the practical installation process of the present utility model, when it is necessary to replace the air filter paper, the upper edge guard and the lower edge guard can be directly separated, and then the air filter paper can be taken out, which is very convenient. It ensures that each time the air filter element is replaced, the filter paper can be replaced separately, which is more energy-saving and environment-friendly.
[0013] The following further describes in detail the specific implementation manners of the present utility model with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.
[0021] As Figures 1 to 4 shown, the dust removal air filter element includes an upper edge guard 1 and a lower edge guard 2, which are covered at the bottom of the upper edge guard 1; an air filter paper 3, which is sealed and clamped between the upper edge guard 1 and the lower edge guard 2; an overlapping boss 5 is integrally provided on the outer edge of the upper edge guard 1; and a reinforcing rib 6 is embedded in the overlapping boss 5; the upper edge guard 1 and the lower edge guard 2 are tightly clamped and sealed with each other through a clamping component.
[0022] As Figures 1 to 4 shown, in the specific implementation manner, the clamping component includes a snap buckle strip 4 integrally installed at the bottom of the upper edge guard 1; and further includes a snap buckle groove 7 opened on the lower edge guard 2, and the snap buckle strip 4 is vertically aligned and clamped with the snap buckle groove 7. In this setting, the purpose of sealing is achieved by combining the snap buckle groove 7 and the snap buckle strip 4.
[0023] As Figures 1 to 4As shown, further, the lower end of the loop fastener strip 4 is arrow-shaped, and the reinforcing rib 6 extends into the upper edge 1. The reinforcing rib 6 can prevent deformation when the upper edge 1 is pressed by the air filter box for a long time. This setting can extend the service life. "V"-shaped sealing grooves 8 are provided at the inner cavity edges of the opposite sides of the upper edge 1 and the lower edge 2 to adapt to the folded corners of the air filter paper 3, so that each time a new air filter paper 3 is replaced, its edges can better fit and lap in the upper edge 1 and the lower edge 2 to achieve a sealing effect.
[0024] The implementation principle of the dust removal air filter element in this embodiment is as follows: During actual installation, when the air filter paper 3 needs to be replaced, the upper edge 1 and the lower edge 2 can be directly separated, and then the air filter paper 3 can be taken out, which is very convenient. It ensures that each time the air filter element is replaced, the filter paper can be replaced separately, which is more energy-saving and environmentally friendly.
