Problems solved by technology

However, as the main body works for a long time, gas will be generated intermittently, and as the gas increases, the air pressure in the sealed space will increase
If these gases are not discharged in time, there may be potential safety hazards
However, if an air vent is provided on the casing, the purpose of sealing the main body part cannot be achieved

Abstract

The invention discloses a functional exhaust valve with a breathing effect and a preparation method thereof. The functional exhaust valve with the breathing effect comprises a base material and a high-pressure breathable layer, wherein the base material is provided with at least one set of exhaust holes penetrating through the top and the bottom of the base material; the high-pressure breathable layer is compounded and covered at at least one side of the base material and blocks the exhaust holes.

Description

technical field [0001] The invention relates to an exhaust valve, in particular to a functional exhaust valve with breathing effect and a preparation method thereof. Background technique [0002] In 2020, China proposed at the 75th United Nations General Assembly to realize the carbon peak commitment by 2030, further pushing the new energy industry to the industry wave, and an important part of new energy is the storage device of clean electric energy (lithium-ion battery , Na-ion batteries, potassium-ion batteries, lithium-sulfur batteries, lithium-air batteries, fuel cells, solid-state batteries, etc.), the following is an example of the current largest output of lithium-ion batteries. At present, lithium-ion batteries have different material systems, different manufacturing processes, different electrical performance ranges, different cell models, and different cell shells. The scope of use ranges from Bluetooth headsets, smart wearable devices, to electric vehicles. , e...
