Description
Technical field
The utility model relates to a kind of air purifier filter core.
Background technology
In recent years, along with the raising of people's living standard, sharply increasing of the quantity such as building, automobile, industrial pollution is simultaneously day by day serious, cause the discharge rate of pernicious gas to increase, indoor-outdoor air quality is all caused to having a strong impact on, and indoor air quality is particularly crucial to Health Impact.Human living standard constantly promotes and health perception is also constantly competed, therefore one of room air pollution, the indoor air quality focus becoming global concern.
Air cleaner Main Function is minute dust, pernicious gas and other harmful substances in filtered air, is applicable to indoor purifying.Filtration body part generally contains multiple filtration structure, as antibacterial and mouldproof layer, pernicious gas adsorption layer, dust filtering layer etc.The material great majority of filtration core adopt non-woven fabrics frame, but the strong hardness of non-woven fabrics frame is not high, is easily out of shape, and especially in use for some time, distortion can be more obvious, and appearance tactile impression is coarse.
Also some filtration core can use the frame material of papery at present, and the frame material of papery is under affecting by humiture, and distortion is comparatively large, and stationarity is deteriorated.Filter core after distortion, is not close to the interior contact of air cleaner, produces gap, reduces filter efficiency, affects overall performance.Therefore in order to improve the distortion of filter core, promote texture, frame material brings into use resin edge.
As be mentioned in Chinese publication CN20110343547.8 filter core material affixed enter on plastic frame, although this method can change the stiffness of filter core, be distorted and be out of shape adding the discounting body easily making filter core man-hour, physical dimension is built on the sand.
Utility model content
The purpose of this utility model is to provide the air purifier filter core that a kind of physical dimension is more firm, texture is superior.
Technical solution of the present utility model is as follows: a kind of air purifier filter core, the filtration body (2) comprising external frame (1) and embed in framework, described external frame (1) is a synthetic resin, and be made up of upper cover (1-1) and bottom (1-3), described upper cover (1-1) is containing an opposite side, described to edge contraction oppositely extend to form inner groovy (1-2), and the flanging (2-1) of coated filtration body (2).
The beneficial effects of the utility model are: air purifier filter core of the present utility model has the advantages that purification of air is thorough, physical dimension is stablized, texture is superior, make simplification.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model; Fig. 2, Fig. 3 are three-dimensional exploded view of the present utility model; In figure, 1: external frame, 1-1: upper cover, 1-2: inner groovy, 1-3: bottom, 2: filtration body, 2-1: flanging, 2-2: the pleated structure sheaf of mountain shape, 2-3: deodorizing filter course.
Detailed description of the invention
Air purifier filter core of the present utility model, the filtration body (2) comprising external frame (1) and embed in framework, described external frame (1) is a synthetic resin, and be made up of upper cover (1-1) and bottom (1-3), described upper cover (1-1) is containing an opposite side, described to edge contraction oppositely extend to form inner groovy (1-2), and the flanging (2-1) of coated filtration body (2), namely there is inner groovy (1-2) on the both sides, inner side of the upper cover (1-1) of synthetic resin.In order to make filter core have better stability, permanent use is not yielding yet, the synthetic resin that this external frame adopts injection mo(u)lding to obtain.In order to fix filtration body, the filtration body that bracketing is embedded into, reduces the distortion on mountain, the flanging of filtration body for also oppositely extending to form inner groovy containing a pair edge contraction, and envelopes, so just without the need to using PUR by synthetic resin, thus decrease operation, reduce production cost.The upper cover of above-mentioned synthetic resin is by resin injection molding, and resin can be PP raw material or ABS raw material.
The height of inner groovy of the present utility model (1-2) is 20 ~ 80% of flanging (2-1) height of filtration body.If height is lower than 20%, the flanging embedding filtration body easily comes off, and is difficult to be fixed; If height is higher than 80%, flanging is not easy to put into, and affects dressing efficiency.Preferred inner groovy height is 30 ~ 60% of the flanging height of filtration body.
Filtration body of the present utility model (2) at least comprises the pleated structure sheaf of one deck mountain shape (2-2), the pleated structure sheaf of this mountain shape is formed through giving a discount by non-woven fabrics, be folded into the structure of " V " type or similar " V " type, make to increase filter area in limited space, thus improve the filter efficiency of filter core.
In order to make shape pleated side in mountain fully be combined with resin edge, above-mentioned inner groovy (1-2) is vertical with the pleated side of mountain shape, is not therefore provided with inner groovy in the pleated side of mountain shape.
Filtration body of the present utility model (2) also comprises deodorizing filter course (2-3), and this deodorizing filter course is non-woven fabrics form or ojosa etc., and has the filter course of deodorization functions.This deodorizing filter course can be the function with removing toluene, formaldehyde, acetaldehyde, acetic acid etc., also can be there is antibacterial, antiallergy etc. can other effect.
In order to avoid framework and filtration body disengaging or loosen, the upper cover (1-1) of external frame of the present utility model (1) and bottom (1-3) be bonded as ultrasonic bonds or PUR bonds.
Below in conjunction with embodiment more detailed description the utility model, but the utility model is not limited to the scope of embodiment.
