Abstract

The utility model discloses a filter element assembly of an air filter, which is formed by means of hot pressing non-woven fabrics and comprises sealed end faces and a filter disc. The sealed end faces are positioned at two ends of the filter disc, and the filter disc is wavy. The filter element assembly of the air filter is formed by means of hot pressing the non-woven fabrics, and accordingly cost is lowered.

Description

The element kit of air-strainer

Technical field

The utility model relates to a kind of air-strainer, particularly a kind of element kit of air-strainer.

Background technique

Air-strainer is the device that a kind of air purifies; It is filtered suction tude, empty filter body assembly structure, sky by sky and leaches tracheae and form; Empty filter body assembly structure comprises upper shell assembly, lower shell body assembly and element kit, and element kit is arranged in the housing with rational structure.Leaching tracheae through sky is connected with engine intake and is used for filtering atmosphere various foreign matters, for example dust, sand grains etc. are arranged.If filter directly entering motor without air-strainer, various foreign matters will speed up the wearing and tearing of motor, thereby reduce the working life of motor.Sometimes tire can take up slungshot, in case get into motor, just can make motor badly damaged.

As shown in Figure 1; Existing element kit adopts the papery filter core, the papery filter core comprise filter paper 1 and polyurethane (Polyurethane, PU) foaming structure 2; Polyurethane foam structure 2 pressurized in upper shell assembly and lower shell body assembly plays sealing effect, but the cost of papery filter core is too high.

The model utility content

The utility model technical problem to be solved provides a kind of element kit of air-strainer, and it is hot-forming through nonwovens, reduces cost.

For solveing the technical problem; The utility model provides a kind of element kit of air-strainer, it is characterized in that, the element kit of air-strainer is hot-forming and comprise seal face and filter disc through nonwovens; Seal face is positioned at the two ends of filter disc, filter disc be shaped as waveform.

Preferably, the element kit of said air-strainer is clipped between a upper shell assembly and the lower shell body assembly.

Preferably, the width of said filter disc be filter disc length 1/2nd to 1/3rd.

The positive progressive effect of the utility model is: the utility model has been avoided the situation of single use papery filter core in the air-strainer, makes nonwovens make filter core through hot-forming back and is able in air-strainer, be widely used.In addition, the utility model is done filter core with nonwovens, and not only economy but also environmental protection have reduced the cost of element kit.

Description of drawings

Fig. 1 is the structural representation of the element kit of existing air-strainer.

Fig. 2 is the fundamental diagram of the element kit of the utility model air-strainer.

Fig. 3 is the structural representation of the element kit of the utility model air-strainer.

Embodiment

Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.

As shown in Figures 2 and 3; The element kit of the utility model air-strainer adopts nonwovens filter core 13; Nonwovens filter core 13 is clipped between upper shell assembly 11 and the lower shell body assembly 12, and nonwovens filter core 13 is hot-forming through nonwovens, and nonwovens filter core 13 comprises seal face 131 and filter disc 132; Seal face 131 is positioned at the two ends of filter disc 132, filter disc 132 be shaped as waveform.The width D of filter disc 132 be filter disc 132 length L 1/2nd to 1/3rd.

The element kit of the utility model air-strainer has been avoided the situation of single use papery filter core in the air-strainer, makes nonwovens make filter core through hot-forming back and is able in air-strainer, be widely used.In addition, the utility model is done filter core with nonwovens, and not only economy but also environmental protection have reduced the cost of element kit.

Though more than described the embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, the protection domain of the utility model is limited appended claims.

Claims

1. the element kit of an air-strainer is characterized in that, the element kit of air-strainer is hot-forming and comprise seal face and filter disc through nonwovens, and seal face is positioned at the two ends of filter disc, filter disc be shaped as waveform.

2. the element kit of air-strainer as claimed in claim 1 is characterized in that, the element kit of said air-strainer is clipped between a upper shell assembly and the lower shell body assembly.

3. the element kit of air-strainer as claimed in claim 1 is characterized in that, the width of said filter disc be filter disc length 1/2nd to 1/3rd.
