TECHNICAL FIELD

[0001] The utility model relates to an air filter element module and belongs to the technical field of gas filtration. BACKGROUND

[0002] In the automobile air conditioner filtering system, the filter element is composed of the non-woven fabric filter layer with the wave structure to achieve the preliminary filtering effect on the air, mainly intercepting dust, foreign matters and the like, and some filter elements further improve the filtering effect by adding the active carbon layer and the like through the adsorption effect. However, these filter elements are difficult to effectively inhibit the bacteria in the air, and the further increase of the filter layer with the bacteriostatic effect on the filter element module can be improved, but is easy to affect the airflow.

[0003] The loading of the bacteriostatic volatile substance on the filter element module can play a good bacteriostatic effect, but the effective time of the bacteriostatic volatile substance is shorter than the effective time of the filter element module for intercepting the dust and foreign matters, so the service life of the filter element module can be prolonged by supplementing the bacteriostatic volatile substance. However, it is a problem to be solved to set what structure to conveniently fix and replace the bacteriostatic volatile substance without affecting the airflow. SUMMARY

[0004] In view of the defects of the prior art, the utility model provides a vehicle bacteriostatic air filter element module to solve the replacement and fixing problems of the bacteriostatic volatile substance and minimize the influence on the airflow.

[0006] Further, the clamping piece is an elastic piece with an arc-shaped cross section, and the central angle corresponding to the arc-shaped is more than 200°.

[0007] Further, the central angle corresponding to the arc-shaped is 220°-280°.

[0008] Further, the arc-shaped elastic piece is provided with at least two, and the elastic pieces are connected through a connecting piece.

[0009] Further, the connecting piece extends along the length direction of the bacteriostatic module.

[0010] Further, the arc-shaped elastic piece is reversely bent into a V-shaped structure at the opening position.

[0011] Further, the bacteriostatic module is in a columnar structure, and an axis of the columnar structure extends along the fold line of the wave-shaped filter screen.

[0012] Further, the bacteriostatic module is a cylinder.

[0013] Compared with the prior art, the technical scheme provided by the utility model has the advantages of:

[0014] The utility model discloses a card clamp is arranged on the air inlet side of the wave-shaped filter screen, and the bacteriostatic module can be fixed by the card clamp, and part of the wave-shaped filter screen is clamped between the card clamp and the bacteriostatic module when the bacteriostatic module is clamped into the card clamp, so that the card clamp and the bacteriostatic module are fixed, the bacteriostatic module can be conveniently replaced, and the use cost is reduced.

[0020] The utility model will be further described below in combination with the embodiments, and it should be understood that these embodiments are only used for describing the utility model and are not used for limiting the scope of the utility model, and after reading the description, the various equivalent modifications of the skilled in the art to the description all fall within the range defined by the claims attached to the present application.

[0021] Please combine Figure 1 And Figure 2As shown, the vehicle bacteriostatic air filter module of the present embodiment comprises a wave-shaped filter screen 1, a frame 2, a clamp 3 and a bacteriostatic module 4. The air filter module body formed by the wave-shaped filter screen 1 and the frame 2 is similar to the structure of the existing filter module. The wave-shaped filter screen 1 is made of non-woven fabric with the function of filtering and intercepting dust particles by folding multiple times. The V-shaped space formed between the adjacent folded surfaces 101 of the wave-shaped filter screen 1 is towards the air inlet side and the air outlet side of the vehicle bacteriostatic air filter module.

[0022] The frame 2 made of multiple layers of non-woven fabric, or further reinforced by adding plastic sheets, hard paper sheets, etc., is fixed around the wave-shaped filter screen 1 by glue, forming a cuboid structure as a whole. The frame 2 can keep the wave-shaped filter screen 1 in a specific shape to meet the use requirements.

[0023] Please further refer to Figure 3 , Figure 4 As shown, the clamp 3 and the bacteriostatic module 4 are respectively arranged at the air inlet side and the air outlet side of the wave-shaped filter screen 1. The clamp 3 is made of metal or plastic and has a certain elastic deformation ability, mainly including an elastic sheet 301 with an arc-shaped cross section, and the central angle of the arc shape is more than 200°. The arc-shaped elastic sheet has an opening, which is arranged at the air inlet side of the wave-shaped filter screen 1. The bacteriostatic module 4 comprises a shell 401 and a bacteriostatic volatile substance 402 filled in the shell 401, and the shell 401 has an opening or a hollow structure to release the bacteriostatic volatile substance 402. The bacteriostatic module 4 is arranged at the air outlet side of the wave-shaped filter screen 1, and the bacteriostatic module 4 together with part of the wave-shaped filter screen 1 is clamped into the clamp 3 from the opening of the clamp 3. The clamp 3 and the bacteriostatic module 4 are connected with the wave-shaped filter screen 1, so that the bacteriostatic module 4 is installed on the wave-shaped filter screen 1 to play its bacteriostatic role. This fixing method is assembled after the wave-shaped filter screen 1 is formed, and does not require the structure during the production and manufacturing of the wave-shaped filter screen 1. The bacteriostatic volatile substance 402 in the bacteriostatic module 4 is a volatile substance with bacteriostatic effect, which can be mustard essential oil (product number: 8007-40-7, Jiangxi Yisenyuan Plant Spice Co., Ltd.) and the like. If a paste-like volatile substance is used, the bacteriostatic volatile substance 402 can be directly filled into the shell 401 of the bacteriostatic module 4. If a liquid volatile substance is used, it can be impregnated on a sponge or other material and then filled into the shell 401 of the bacteriostatic module 4.

[0024] The shell 401 of the bacteriostatic module 4 is made into a columnar structure, for example, a cylinder, or a prism, and the axis of the columnar structure extends along the fold line of the wave-shaped filter screen 1. In order to facilitate the installation of the bacteriostatic module 4 and avoid the damage of the opening of the clamping clip 3 to the wave-shaped filter screen 1, the arc-shaped elastic sheet 301 is reversely bent into a V-shaped structure at the opening position, and the V-shaped structure has a guiding effect on the bacteriostatic module 4. After being clamped into the clamping clip 3, the axis of the columnar structure extends along the fold line of the wave-shaped filter screen 1. In order to ensure that the bacteriostatic module 4 can be clamped stably by the clamping clip and avoid the bacteriostatic module 4 from falling off during the driving of the vehicle, while facilitating the clamping, the arc-shaped center angle of the arc-shaped elastic sheet 301 of the clamping clip 3 is preferably 220°-280°.

[0025] Since the bacteriostatic module 4 is in a columnar structure, and the axis of the columnar structure extends along the fold line of the wave-shaped filter screen 1, when the bacteriostatic module 4 has a relatively long length, the fixing ability of a single arc-shaped elastic sheet 301 to the bacteriostatic module 4 is limited, and extending the arc-shaped elastic sheet 301 on the axis of the columnar structure and increasing the width thereof will increase the difficulty of clamping the bacteriostatic module. Therefore, the clamping clip 3 can be provided with a plurality of arc-shaped elastic sheets 301, and the plurality of arc-shaped elastic sheets 301 are connected by a connecting sheet 302 extending along the length direction of the bacteriostatic module 4. In this way, during the installation, the bacteriostatic module 4 can be clamped into the arc-shaped elastic sheets 301 one by one, without increasing the installation difficulty, and the stable connection can be ensured. The connecting sheet 302 is generally connected to the middle position of each arc-shaped elastic sheet 301, and can be integrally made with each arc-shaped elastic sheet 301.

[0026] When the inlet air speed is set to 1 m / s, the vehicle bacteriostatic air filter module of the embodiment and the conventional air filter module without the bacteriostatic module 4 (i.e., the filter core only having the frame 2 and the wave-shaped filter screen 1) are simulated. The results show that the outlet flow of the vehicle bacteriostatic air filter module of the embodiment can reach more than 97% of the outlet flow of the conventional air filter module, proving that the vehicle bacteriostatic air filter module of the embodiment has little effect on the air flow.
