[0027] like Figures 1 to 3 As shown, a moisture permeability, air permeability and waterproof tester comprises an upper cup body 1, a lower cup body 2 and a steam generator 3; both the upper cup body 1 and the lower cup body 2 are transparent, so as to observe the moisture permeability, air permeability and waterproof test effect in the cup body; the upper cup body 1 is detachably mounted on the lower cup body 2, the bottom of the upper cup body 1 and the top of the lower cup body 2 are connected to allow gas and liquid to flow, and the upper and lower cup bodies are sealed and connected by a sealing ring or a sealing rubber pad to prevent water leakage and air leakage; the test material is horizontally laid and placed between the upper cup body 1 and the lower cup body 2, and is pressed by the upper and lower cup bodies to make the surface of the test material taut; an opening 11 is provided on the upper half of the upper cup body 1 to facilitate the emergence of steam and the injection of test liquid; the steam generated by the steam generator 3 is passed into the lower cup body 2.

[0028] The test process of this embodiment is as follows: when testing the moisture permeability and breathability, the power is turned on, and the high-temperature steam generated by the steam generator 3 is continuously injected into the lower cup body 2. The steam rises in the lower cup body 2 and passes through the moisture permeable and breathable material to be tested and is injected into the upper cup body 1. Therefore, the upper cup body 1 and the lower cup body 2 can observe the presence of water vapor, which proves that the material is a moisture permeable and breathable material; finally, the steam in the upper cup body 1 emerges from the upper opening 11 of the upper cup body 1 to avoid excessive accumulation of steam in the upper cup body 1 and cause bursting. On the contrary, if no steam appears in the upper cup body 1, it proves that the test material is not moisture permeable and breathable. When testing the waterproof performance, pure water is injected from the upper opening 11 of the upper cup body 1. How to observe whether the water will leak from the upper cup body 1 through the test material to the lower cup body 2 under the action of gravity, so as to judge whether the test material has a waterproof function. There is no need to replace or repeatedly install the test material during the two tests, which improves the test efficiency. The structural design of this embodiment is reasonable. Through the ingenious design of the upper and lower cup bodies, on the one hand, the fluidity and penetration of high-temperature steam can be used to test the moisture permeability and air permeability of the test material, and on the other hand, the gravity of the liquid itself can be used to test the waterproof performance of the test material; the operation is simple and convenient, the test effect is intuitive and accurate, which enriches the test function of the equipment and improves the test efficiency.

[0029] During the specific implementation of this embodiment, the steam generator 3 includes a heater body 31 and a water container 32. The heater body 31 is used to heat and evaporate the liquid in the water container 32 to generate steam. The upper space of the water container 32 is connected to the interior of the lower cup body 2 to allow the steam to pass into the lower cup body 2.

[0030] During the specific implementation of this embodiment, the moisture permeability, air permeability and waterproof tester also includes a reflux pipe 21, which runs from the lower cup body 2 to the water container 32. After the high-temperature steam in the lower cup body 2 is cooled into liquid, it flows back to the water container 32 through the reflux pipe 21 to evaporate again, thereby realizing water circulation and avoiding the cooling liquid from blocking the steam inlet.

[0031] During the specific implementation of this embodiment, an air supply pipe 22 is arranged between the water container 32 and the lower cup body 2. One end of the air supply pipe 22 connected to the lower cup body 2 is higher than the bottom of the lower cup body 2, which can prevent the steam inside the lower cup body 2 from cooling and flowing back to block the air supply pipe 22.

[0032] In the specific implementation of this embodiment, the moisture permeability, air permeability and waterproof tester also includes a water supply device 4, which is connected to the water container 32 through a water supply pipeline to supply water to the water container 32, so that the steam generator 3 is continuously heated to generate high-temperature steam. Among them, the return pipeline 21 is connected to the water supply pipeline of the water supply device 4, and the return liquid merges into the water supply flow and then flows to the water container 32, which simplifies the pipeline design and is also conducive to the water supply flow to further cool the return liquid.

[0033] During the specific implementation of this embodiment, a movable connection mechanism 5 is provided between the upper cup body 1 and the lower cup body 2 to achieve a detachable connection between the upper cup body 1 and the lower cup body 2, so as to facilitate laying and placing the test material between the upper cup body 1 and the lower cup body 2.

[0034] During the specific implementation of this embodiment, the movable connection mechanism 5 includes buckles 51 arranged on both sides of the lower cup body 2 and buckle hooks 52 arranged on both sides of the upper cup body 1, and the buckles 51 and the buckle hooks 52 on both sides cooperate with each other.

[0035] In the specific implementation of this embodiment, the upper cup body 1 is made of transparent material, and the lower cup body 2 is made of transparent material. Both the upper and lower cup bodies are made of fully transparent materials, which is convenient for observing the moisture permeability, air permeability and waterproof test results inside the cup body.

[0036] In the specific implementation of this embodiment, the moisture permeability, air permeability and waterproof tester further includes a thermostat, which is electrically connected to the steam generator 3. When the temperature of the steam generator 3 is too high, the thermostat is triggered to disconnect the circuit, thereby preventing dry burning and protecting the entire container and circuit.

[0037] Regarding the embodiments of the present utility model, it should also be noted that, in the absence of conflict, the embodiments of the present utility model and the features therein can be combined with each other to obtain new embodiments.

[0038] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. The protection scope of the utility model shall be based on the protection scope of the claims. Although the utility model has been disclosed as a preferred embodiment, it is not used to limit the utility model.
