Detailed implementation mode

[0027] Refer to Figures 1-10 As shown, the technical solution adopted in this detailed implementation mode is as follows: It includes a support base 5. An inflatable air pump 6 is installed on one side of the support base 5. A pressure gauge 7 is provided on the inflatable air pump 6. In the middle above the support base 5, a test mold 4 is installed. A support frame 2 is installed on the side of the test mold 4. A test lifting mechanism 1 is installed on the support frame 2. A test nozzle 3 is installed on the output end of the test lifting mechanism 1. The test nozzle 3 and the test mold 4 are correspondingly matched with each other. A water storage device 8 is installed on one side of the upper end of the support base 5. The water storage device 8 is interconnected with the test nozzle 3.

[0028] More specifically, the test nozzle 3 includes a test end 31. A tee connecting pipe 33 is installed on one side of the test end 31. The other end of the tee connecting pipe 33 is installed with a connecting tee 32. A water pipe connecting pipe 34 is installed on the other side of the test end 31. A docking nozzle 35 is installed below the test end 31. Test through holes 36 are provided on both the test end 31 and the docking nozzle 35. When testing the waterproof and breathable film, the test lifting mechanism 1 will drive the test nozzle 3 to move downward, so that the docking nozzle 35 fits the waterproof and breathable film to be tested, and the test through hole 36 is sealed by the waterproof and breathable film. When testing, the water source will flow from the water storage device 8 through the water pipe connecting pipe 34 to the test end 31 and be discharged through the test through hole 36 to test the waterproof performance of the waterproof and breathable film. And the air pressure will be introduced into the test end 31 through the connecting tee 32 and the tee connecting pipe 33. When drainage operation is required, a drainage pump can also be connected through the connecting tee 32 to quickly discharge the water source.

[0029] More specifically, the connecting tee 32 includes a discharge nozzle A for discharging water source and gas, an air pump connecting nozzle B for connecting the inflatable air pump 6, and an intercommunicating connecting nozzle C for connecting the tee connecting pipe 33.

[0030] More specifically, the test mold 4 includes a mold body 41. A placement groove 42 is formed by inward depression in the middle of the mold body 41, and an intercommunicating through-hole 43 is provided in the placement groove 42. When testing the waterproof and breathable film, the staff only needs to place the waterproof and breathable film at the placement groove 42. When the waterproof effect of the waterproof and breathable film is poor, the water source will be discharged in time through the intercommunicating through-hole 43, preventing the water source from being squeezed on the mold body 41.

[0031] More specifically, the water storage device 8 includes a water storage tank 85. A lower support plate 86 is installed below the water storage tank 85. A water delivery mechanism 81 is installed on one side above the lower support plate 86. The water delivery mechanism 81 is connected to the water storage tank 85 through a water delivery pipe 82, and the water delivery mechanism 81 is connected to its test nozzle 3 through the water delivery pipe 82. An upper support plate 84 is installed above the water storage tank 85. A water tank pressure gauge 87 is installed on one side below the upper support plate 84. The water tank pressure gauge 87 is connected to the water storage tank 85. An inlet funnel 83 is provided at the top of the water storage tank 85. A drain valve 88 is installed on one side of the bottom of the water storage tank 85. When water is needed to test the waterproof and breathable film, the water delivery mechanism 81 can deliver the water source from the water storage tank 85 to the test nozzle 3, facilitating the test of the waterproof and breathable film by the test nozzle 3. Among them, the staff can replenish water to the water storage tank 85 through the inlet funnel 83, observe the water volume of the water storage tank 85 through the water tank pressure gauge 87, and when the water source needs to be drained, the staff can drain the water source through the drain valve 88.

[0032] More specifically, a cylinder connecting rod 1-1 is provided on the test lifting mechanism 1, and a test nozzle 3 is installed on the cylinder connecting rod 1-1. The test lifting mechanism 1 can control the lifting operation of the test nozzle 3, facilitating the test of the waterproof and breathable film by the test nozzle 3.

[0033] More specifically, a cylinder mounting plate 2-1 is installed on the support frame 2, and the test lifting mechanism 1 is installed on the cylinder mounting plate 2-1.

[0034] More specifically, an anti-slip bottom pad 5-1 for increasing the stability of the device is provided at the bottom of the support base 5.

[0035] Working principle of the utility model: When it is necessary to test the waterproof and breathable performance of the waterproof and breathable membrane, the staff can use this device for testing. When testing the waterproof and breathable membrane, the staff only need to place the waterproof and breathable membrane on the test mold 4, and then drive the test nozzle 3 to move downward through the test lifting mechanism 1 to form a sealed space between the docking nozzle 35 and the waterproof and breathable membrane. Then, water is conveyed to the test nozzle 3 through the water storage device 8, and pressurization operation is carried out through the inflation air pump 6. When the pressure reaches a certain level, the pressurization stops. If the waterproof performance of the waterproof and breathable membrane meets the requirements, the pressure index of the pressure gauge 7 will not change. If the waterproof performance of the waterproof and breathable membrane does not meet the requirements, the water source will flow out through the waterproof and breathable membrane. At this time, the pressure index of the pressure gauge 7 will continuously decrease, and it can be judged that the waterproof performance of the waterproof and breathable membrane does not meet the requirements. After the test is completed, the staff can pump away the water source through an external water pump. At this time, the air permeability of the waterproof and breathable membrane can be judged through the water flow effect.

[0036] The above is only used to illustrate the technical solution of the utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the utility model shall be covered by the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
