Description
Technical Field
The utility model relates to an elastic film, in particular to an elastic film with micropores and ventilation.
Background
The outer surfaces of products such as waterproof materials, sanitary materials, masks, paper diapers and sanitary towels need to be waterproof, waterproof treatment is needed, although the outer surfaces of the products need to be waterproof, the products need to be breathable at the same time, and the waterproof effect cannot be achieved by using a sealing mode.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an elastic film with micropore is ventilative is provided, has solved current waterproof ventilative material when using, or the gas permeability is poor that water-proof effects is good, or the poor problem of water-proof effects is good to the gas permeability.
In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides an elastic film with micropore is ventilative, includes elastic film main part, ventilative boss and bleeder vent, elastic film main part upper end is the smooth surface, elastic film main part bottom is the mat surface, the integrative arch in elastic film main part bottom is equipped with ventilative boss, ventilative boss bottom is equipped with the bleeder vent.
On the basis of the scheme, the plurality of breathable bosses are uniformly arranged on the elastic film main body.
On the basis of the scheme, the center distance between the air-permeable bosses is 2 mm-10 mm, and the size of the air holes is 0.5 mm-1 mm.
On the basis of the scheme, the ventilating boss is in a horn mouth shape.
On the basis of the scheme, the opening of one end, located at the smooth surface of the elastic film main body, of the horn-mouth-shaped ventilating boss is large, and the opening of the ventilating hole, located at one end, far away from the smooth surface of the elastic film main body, of the horn-mouth-shaped ventilating boss is small.
Compared with the prior art, the utility model beneficial effect who has is: the utility model provides an elastic film with micropore is ventilative, set up the ventilative boss of horn mouth shape in the elastic film main part, breathe freely through the loudspeaker osculum, when having water to spill in the elastic film main part, when ventilative boss receives the impact force, the osculum of horn mouth outer end will contract, water can not follow the inboard that the venthole department entered into the elastic film main part, after water landing leaves the elastic film main part, the bleeder vent of horn mouth outer end can be stretched out, be convenient for breathe freely, even the bleeder vent does not contract, because the bleeder vent is smaller, water also hardly enters into the elastic film main part from the bleeder vent inboard, the utility model has the advantages of simple and reasonable structure, waterproof gas permeability is good, and the cost of manufacture is low, and the practicality is strong.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Referring to fig. 1 to 3, the microporous breathable elastic film comprises an elastic film main body 1, breathable bosses 2 and breathable holes 3, wherein the upper end of the elastic film main body 1 is a smooth surface, the bottom end of the elastic film main body 1 is a rough surface, the raised breathable bosses 2 enable the surface of the elastic film main body 1 to form the rough surface, the breathable bosses 2 are integrally and convexly arranged at the bottom end of the elastic film main body 1, and the breathable holes 3 are arranged at the bottom ends of the breathable bosses 2. The air holes 3 are convenient for ventilation.
The plurality of air-permeable bosses 2 are uniformly arranged on the elastic film main body 1, and the plurality of air-permeable bosses 2 have good air permeability; the center distance between the air-permeable bosses 2 is 2 mm-10 mm, the size of the air-permeable holes 3 is 0.5 mm-1 mm, and the air-permeable bosses can be arranged according to actual use conditions; the air-permeable boss 2 is in a horn mouth shape, and the using performance is good; the one end opening that ventilative boss 2 of horn mouth shape is located 1 smooth surface of elastic film main part is big, 3 openings of bleeder vent that ventilative boss 2 of horn mouth shape kept away from 1 smooth surface one end of elastic film main part are little, can let water hardly enter into 1 inboards of elastic film main part.
The utility model discloses a principle and advantage: an elastic film with micropore ventilation, when in use, an elastic film main body 1 is fixedly connected with the outer surfaces of products such as waterproof materials, sanitary materials, masks, paper diapers, sanitary towels and the like, the smooth surface of the elastic film main body 1 is arranged at the inner side, one side with a ventilation boss 2 is arranged at the outer side, when water is sprinkled on the ventilation boss 2 at the outer side of the elastic film main body 1, the ventilation boss 2 can be compressed by the impact force of the water, the ventilation holes 3 at the outer end of the ventilation boss 2 can be closed to prevent the water from entering the inner side of the elastic film main body 1, even if the ventilation holes 3 on the ventilation boss 2 are not compressed, the ventilation holes 3 are very small and are still convex, the water is difficult to enter the inner side of the elastic film main body 1, the waterproof performance of the product is improved, when in use, the number of layers of the elastic film main body 1 can be increased according to the required thickness, the utility model has the advantages of simple and reasonable structure, waterproof gas permeability is good, and the cost of manufacture is low, is fit for using widely.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
