Description

Waterproof air permeability presentation device of surface fabric Technical Field The utility model belongs to the technical field of textiles, and particularly relates to a fabric waterproof and breathable performance demonstration device. Background Waterproof and breathable are two important indicators for evaluating fabric properties. In the related art, the waterproof property and the air permeability of the fabric can be detected only by a professional detecting instrument, and then the waterproof property and the air permeability of the fabric are described by detecting data. This approach is cumbersome and inconvenient to display the fabric to the consumer. To solve the above problems, patent document publication No. CN201796518U discloses a waterproof and breathable demonstration cup for demonstrating cloth properties. The waterproof breathable demonstration cup comprises an upper cup and a lower cup, wherein the upper cup and the lower cup are made of transparent materials, a water injection hole is formed in the bottom of the upper cup, a round base with the diameter larger than that of the bottom of the lower cup is arranged at the bottom of the lower cup, the lower cup is placed more stably, an air inlet is formed in the wall of the lower cup, a door-shaped support is movably arranged, and a fastening screw is arranged at the top of the door-shaped support. The waterproof breathable demonstration cup is made of transparent materials, and the demonstration effect can be visually represented. Because the structure of the upper cup and the lower cup is adopted, the upper cup can be filled with water, the lower cup can be externally connected with an air pump for inflation, and the waterproofness and the air permeability can be simultaneously demonstrated. The waterproof breathable demonstration cup has the advantages of simple structure, small volume and portability, and can be widely applied to demonstration in various occasions. However, this waterproof ventilative demonstration cup is not applicable to the waterproof demonstration demand of the thicker surface fabric of thickness, if the thickness of surface fabric is greater than or equal to 1mm, then the laminating nature between surface fabric and the waterproof ventilative demonstration cup is not good, and the leakproofness is relatively poor, and the edge is easy infiltration, and the demonstration effect is not good. In other words, the waterproof breathable demonstration cup cannot meet the waterproof demonstration requirements of fabrics with different thicknesses. Disclosure of utility model In view of the above, the utility model provides a fabric waterproof and breathable performance demonstration device to solve the technical problems that the waterproof and breathable demonstration cup cannot meet the waterproof demonstration requirements of fabrics with different thicknesses. In order to realize the scheme, the technical scheme of the utility model is as follows: The utility model provides a fabric waterproof and breathable performance demonstration device, which comprises: The demonstration cavity comprises a lower cavity and an upper cavity detachably arranged on the lower cavity, the bottom of the upper cavity and the top of the lower cavity are both open, the top of the upper cavity is provided with a water filling port, and the side wall of the lower cavity is provided with an air inlet; Two fasteners respectively positioned at two sides of the demonstration cavity for fastening the upper cavity and the lower cavity during demonstration, and Two sealing gaskets. The principle of the fabric waterproof and breathable performance demonstration device is that by additionally arranging the two sealing gaskets, gaps between the opening at the bottom of the upper cavity and the fabric and gaps between the opening at the top of the lower cavity and the fabric can be sealed by the sealing gaskets during demonstration, so that the adhesiveness and the tightness between the fabric and the demonstration device during demonstration are improved, and the problems that in the prior art, the adhesiveness between the fabric and a waterproof and breathable demonstration cup is poor, the tightness is poor, the edge is easy to permeate water, the demonstration effect is poor and the like are avoided. In an example of the fabric waterproof and breathable performance demonstration device, the surface of the sealing gasket is coated with a hydrophobic coating. Specifically, the hydrophobic coating is coated on the surface of the sealing gasket, so that water stain residues can be prevented, and negative influences of the water stain residues on ageing, oxidization, sealing effect reduction and the like of the sealing gasket are avoided. In an example of the fabric waterproof and breathable performance demonstration device, the surface of the sealing gasket is provided with a plurality of containing grooves so as to facilitate bonding of the two se
