Abstract
The invention discloses a waterproof breathable filter, which comprises a shell body, an elastic breathable material layer and a waterproof breathable film, wherein the upper and the lower ends of the shell body are respectively provided with a breathable hole, the waterproof breathable film is positioned on the bottom wall of the inner cavity of the shell body and covers the breathable holes of the bottom of the shell body, the elastic breathable material layer covers the waterproof breathable film, and the top part of the elastic breathable material layer is abutted to the top part of the shell body. The waterproof breathable filter has a more firm structure, and is convenient to be changed and maintained.
Description
Technical field
The present invention relates to a kind of water-proof breathable filter, especially in breathable shoes for waterproof and breathable.
Background technology
In the product that tradition breathable shoes or other need to be ventilative, just waterproof ventilated membrane is attached on object, directly utilize the waterproof and breathable function that waterproof ventilated membrane self has to realize waterproof and breathable, but this setup often structure is firm not, and be not easy to waterproof ventilated membrane to carry out local replacing and maintenance, while the most important thing is that waterproof ventilated membrane is pushed by hard thing, cannot be cushioned, be easy to breakage.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of water-proof breathable filter, and this water-proof breathable filter structure is more firm, and easy to replace and maintain.
For this reason, water-proof breathable filter provided by the invention, comprise housing, air-permeable elastic material layer and waterproof ventilated membrane, the upper and lower side of housing offers respectively air-vent, air-vent on the diapire of waterproof ventilated membrane in housing inner chamber and bottom covering shell, air-permeable elastic material layer covers on waterproof ventilated membrane, and top and the case top of air-permeable elastic material layer are pressed close to.
Air-permeable elastic material layer and the waterproof ventilated membrane of in water-proof breathable filter provided by the invention, realizing waterproof and breathable effect are arranged in housing, therefore can realize by offer mounting groove on product the setting of water-proof breathable filter, this structure is firm and durable very, is particularly useful for various breathable shoes products.In addition, by mounting groove and water-proof breathable filter are set in a large number, can expand the region that possesses waterproof and breathable function, and water-proof breathable filter wherein can keep in repair one by one at any time and change when damaging, and then can save cost.And, in water-proof breathable filter provided by the invention, waterproof ventilated membrane is pressed on waterproof ventilated membrane by air-permeable elastic material layer, can make waterproof ventilated membrane fully launch and cover air-vent, make its waterproof and breathable better effects if, can also when waterproof ventilated membrane is subject to hard thing and pushes, by air-permeable elastic material layer, be cushioned in time, be made not cracky of waterproof ventilated membrane.
Accompanying drawing explanation
Fig. 1 is the structure cross-sectional schematic of water-proof breathable filter provided by the invention.
Fig. 2 is upper shell in water-proof breathable filter provided by the invention and the chute slide block structure schematic diagram of lower house.
The specific embodiment
As shown in Figure 1, in the first embodiment of water-proof breathable filter provided by the invention, comprise housing 1, air-permeable elastic material layer 2 and waterproof ventilated membrane 3, waterproof ventilated membrane 3 possesses ventilative coating materials that also can waterproof for existing, air-permeable elastic material layer 2 consists of sponge material, the upper and lower side of housing 1 offers respectively air-vent 4, the air-vent 4 of on the diapire of waterproof ventilated membrane 3 in housing 1 inner chamber and covering shell 1 bottom, air-permeable elastic material layer 2 covers on waterproof ventilated membrane 3, and the top of air-permeable elastic material layer 2 and housing 1 top are pressed close to.When water-proof breathable filter is arranged on sole, dirty gas in footwear chamber can enter in sponge material by the air-vent 4 at top, then the waterproof ventilated membrane 3 by bottom and air-vent 4 discharge extraneous, and outside outside rainwater is just blocked on when running into waterproof ventilated membrane 3.
As shown in Figure 2, housing 1 in above-described embodiment comprises upper shell 5 and lower house 6, the air-vent 4 of housing 1 upper end is arranged on upper shell 5, the air-vent 4 of housing 1 lower end is arranged on lower house 6, upper shell 5 and lower house 6 are mutually socketed and dispose chute slide block structure guiding upper shell 5 and rise and decline, and the slide block 8 on this upper shell 5 snaps in the chute 7 on lower house 6.In water-proof breathable filter in the present embodiment, upper shell 5 and lower house 6 possess the elastic telescopic function of vertical direction, therefore possesses the effect of buffering and damping, better effects if in particular in various footwear time, in addition, after being extruded, air-permeable elastic material layer 2 can absorb more the dirty gas in footwear chamber, and when air-permeable elastic material layer 2 is released, discharge dirty gas, possess the function of auxiliary exhaust.
As shown in Figure 1, the second embodiment of the present invention and the first embodiment are basic identical, and its difference is only: housing 1 is fixed as one, and the housing 1 being fixed as one can strengthen firmness.
