Problems solved by technology

Since the breathable valve encapsulates the breathable membrane in a plastic shell, the existing packaging technology uses glue and ultrasonic technology to fuse the two. The packaging design and technology between the breathable membrane and the valve body are not good enough, and the force is not enough. Or improper force will ca

Example Embodiment

[0022] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] Such as Figure 1 ~ Figure 3 As shown, the waterproof and breathable valve of the present invention includes a screw cap 1, a screw 2, an insert 3, and a waterproof and breathable membrane. A through hole 21 is provided inside the screw 2 to communicate with the screw cap 1. And the waterproof and breathable membrane is encapsulated in the nut 1 through the insert 3. Preferably, the material of the waterproof and breathable membrane is hydrophobic and oil-repellent expanded polytetrafluoroethylene ePTFE. The shape of the nut 1 can be hexagonal as shown in the figure, or other shapes such as round, square, etc.

[0024] Wherein, the insert 3 is an insert with a hole, which can be as figure 2 The circular ring shown can also be designed as an elliptical ring, a box shape, a sieve shape, etc., as required. There is a ring of ri...

Abstract

The invention discloses a waterproof vent valve, which comprises a screw cap, a screw stem, a waterproof vent film and an insert with a hole. The insert can be embedded in the screw cap to contain the waterproof vent film and seal the waterproof vent film in the screw cap. After the scheme is adopted, the invention closely encapsulates the waterproof vent film and a plastic valve together through the simple inset structure and realizes secondary sealing through further hot melting.

Description

technical field [0001] The invention relates to a waterproof breathable valve and a packaging method thereof. Background technique [0002] Outdoor electronic devices, LED lamps, landscape lamps, automotive lamps, sealing equipment, communication equipment, sensors and other equipment that need to be breathable, waterproof and dustproof can reduce the stress of the casing sealing strip by balancing the pressure, and prevent the pressure from accumulating and damaging the casing seal. Maintaining a good ventilation condition avoids the pressure increase of the equipment due to the accumulation of internal gas, which damages the sealing strip of the casing, and makes the internal sensitive electronic components suffer from water and dust attack. Waterproof and breathable valve products can still breathe when the environmental conditions change, which greatly reduces the failure of electronic and inductive products caused by salt corrosion, greatly reduces fogging and condensat...
