Description

Technical Field

[0001] This utility model relates to the field of waterproof and breathable membrane technology, and in particular to a waterproof and breathable membrane waterproof testing device. Background Technology

[0002] Waterproof and breathable membranes are a new type of polymer waterproof material with much higher technical requirements than ordinary waterproof materials. During the production of waterproof and breathable membranes, it is necessary to use a waterproof testing device to check whether their waterproof rating and air permeability meet the requirements. For example, the waterproof testing device for waterproof and breathable membranes in patent (CN213209826U) is convenient for testing waterproof and breathable membranes of different sizes, increasing the applicability of the testing device. However, the overall structure is relatively complex, and the waterproof and breathable membrane needs to be manually fixed during testing, which is inconvenient to operate. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A waterproof and breathable membrane waterproof testing device is designed, including a base, an installation seat in the middle of the base, an abutment cover on the upper surface of the installation seat, a humidity sensor in the inner cavity of the abutment cover, the humidity sensor being connected to an external display terminal via a wire, a telescopic rod on the upper surface of the installation seat, a water storage tank on the top of the telescopic rod, a top cover connected to the bottom of the water storage tank, and a water pump and an external water source connected to the outer wall of the water storage tank via pipes. A waterproof and breathable membrane is sandwiched between the abutment cover and the top cover.

[0005] Preferably, the upper surface of the base is provided with a pair of side plates, the side walls of the side plates are provided with slots, a support plate is inserted into the slots, the outer wall of the support plate is provided with a detection hole, and the support plate is clamped between the abutment cover and the top cover.

[0006] Preferably, an air pump is provided on the upper surface of the base, one end of the air pump is connected to a pipe fitting, the pipe fitting is provided with an air pressure gauge and a one-way valve, and the other end of the air pump is connected to an external air source.

[0007] Preferably, the bottom of the water storage tank is connected to a threaded pipe, and the top of the top cover is threadedly connected to and communicates with the threaded pipe.

[0008] Preferably, a sealing ring is adhered to the upper end face of the abutment cover, and the sealing ring abuts against the outer wall of the tray.

[0009] Preferably, the upper end face of the mounting base is provided with a telescopic rod, and the top of the telescopic rod is connected to an abutment cover.

[0010] The waterproof and breathable membrane waterproof testing device proposed in this utility model has the following advantages: by setting a support plate to support the waterproof and breathable membrane and controlling the telescopic rod to move down, the top cover covers the testing part of the waterproof and breathable membrane. The water pump injects clean water into the top cover. By observing the data detected by the humidity sensor, when the humidity is greater than the indoor humidity, the waterproof performance of the waterproof and breathable membrane is insufficient. At the same time, the air pressure inside the top cover can be adjusted by the air pump to simulate the waterproof performance under different pressure environments, thereby improving the accuracy of the test.
