[0002] Various types of external lights of cars need to use light vent valves. In addition, the car's control unit, also known as the ECU, and car batteries and other products that require ventilation will also use vent valves. The use of vent valves can well achieve the exchange of internal and external gases, and timely discharge the gas generated inside to ensure the reliable use of car lights, ECUs, batteries and other equipment.

When the pressure difference between the inside and outside of the equipment is large, insufficient air permeability will lead to reduced performance of the air valve. Excessive tension of the air membrane will cause damage to the air membrane, thereby causing the air valve to fail. Utility Model Content

[0026] See also Figure 1-6 The utility model provides a technical solution: a high-performance automobile ventilation valve, comprising a mounting seat 1, an adjusting seat 2 and a ventilation seat 3, the adjusting seat 2 is provided with a main ventilation membrane 4, the ventilation seat 3 is provided with a main ventilation hole 5, the mounting seat 1 and the adjusting seat 2 are elastically connected by a spring 6, the position of the adjusting seat 2 relative to the mounting seat 1 is adjustable, the mounting seat 1 is provided with a secondary ventilation hole 7, the secondary ventilation hole 7 is provided with a secondary ventilation membrane 8, and the aperture of the secondary ventilation membrane 8 is larger than the aperture of the main ventilation membrane 4.

[0027] Among them, during normal use, such as Figure 5 As shown, the gas enters the airway 16, passes through the main air permeable membrane 4, and is finally discharged through the multiple groups of main air holes 5 to achieve exhaust. When the internal air pressure of the equipment is too high and the internal and external pressure difference is too large, the adjustment seat 2 slides relative to the mounting seat 1 under the action of the gas pressure, the spring 6 is stretched, and the secondary air holes 7 are connected with the airway 16. At this time, part of the gas passes through the secondary air permeable membrane 8 and is discharged through the multiple groups of secondary air holes 7, and the other part of the gas passes through the main air permeable membrane 4 and is discharged through the multiple groups of main air holes 5. The exhaust volume per unit time is increased through the secondary air holes 7, the exhaust pressure is effectively dispersed, the pressure is released in time, and the main air permeable membrane 4 is prevented from being damaged due to excessive tension, thereby improving the stability and reliability of the automobile air valve.

[0028] Among them, when the internal and external pressure difference returns to the normal range, the spring 6 relies on its own elastic force to drive the adjustment seat 2 to rebound and reset, blocking the multiple groups of secondary air holes 7. At this time, the air valve returns to its initial state and exhausts air through the multiple groups of main air holes 5.

[0029] Among them, by adding the secondary air permeable hole 7 and the secondary air permeable membrane 8, while ensuring the waterproof and air permeable performance of the overall air permeable valve, its air permeability can be adjusted accordingly according to the change of the internal air pressure of the equipment, thereby improving the flexibility of the air permeable valve during use.

[0030] Among them, a connecting seat 10 is provided at one end of the adjusting seat 2, and the connecting seat 10 is embedded in the mounting seat 1, and one end of the spring 6 is fixed to the mounting seat 1, and the other end of the spring 6 is fixed to the connecting seat 10, multiple groups of springs 6 are evenly spaced along the circumferential direction of the mounting seat 1, and multiple groups of springs 6 are arranged between the mounting seat 1 and the adjusting seat 2, so that the connection between the mounting seat 1 and the adjusting seat 2 is an elastic connection.

[0031] Among them, a plurality of slide bars 9 are arranged on the inner wall of the mounting seat 1 , and a plurality of slide grooves 11 are provided on the outer surface of the connecting seat 10 .

[0032] There is a one-to-one correspondence between the multiple groups of slide bars 9 and the multiple groups of slide grooves 11 , and the slide grooves 11 are slidably connected to the slide bars 9 . The multiple groups of slide bars 9 and the multiple groups of slide grooves 11 cooperate with each other to play a guiding and limiting role.

[0033] Among them, a first stud 12 is provided at one end of the mounting seat 1. When installing the integral air valve, the air valve is fixed on the equipment housing through the first stud 12. The air valve is installed by threaded connection, which is convenient for installation and disassembly of the air valve and conducive to maintenance.

[0034] Among them, a sealing ring 13 is arranged on the first stud 12. After the air valve is installed, the sealing ring 13 is located at the connection between the air valve and the device housing to seal the connection, which is effectively waterproof and dustproof.

[0035] An internal thread groove 14 is provided on the inner wall of the adjustment seat 2 .

[0036] Among them, a second stud 15 is provided at one end of the breathable seat 3, the internal thread groove 14 of the adjustment seat 2 is adapted to the second stud 15 of the breathable seat 3, the adjustment seat 2 and the breathable seat 3 are threadedly fixedly connected, and the adjustment seat 2 and the breathable seat 3 are a detachable structure for easy maintenance.

[0037] Among them, the mounting seat 1, the adjusting seat 2 and the venting seat 3 are all provided with air passages 16, and the air passages 16 of the mounting seat 1, the air passages 16 of the adjusting seat 2 and the air passages 16 of the venting seat 3 are connected, such as Figure 5 As shown, when exhausting, the gas first enters the air passage 16 of the mounting seat 1, then enters the air passage 16 of the adjusting seat 2, passes through the main air permeable membrane 4, and finally enters the air passage 16 of the air permeable seat 3, and is finally discharged through the main air permeable hole 5 to achieve exhaust.

[0038] Among them, multiple groups of main air holes 5 are evenly spaced along the circumferential direction of the air seat 3, and multiple groups of secondary air holes 7 are evenly spaced along the circumferential direction of the mounting seat 1. The air valve can ventilate in multiple directions.

[0039] Working principle: When in use, the air valve is fixed to the device housing by the first stud 12, and the sealing ring 13 is located at the connection between the air valve and the device housing to seal the connection. When the pressure difference between the inside and outside of the device is within the normal range, the gas enters the airway 16, passes through the main air permeable membrane 4, and is finally discharged through multiple groups of main air holes 5 to achieve exhaust. When the internal air pressure of the device is too large, resulting in an excessive pressure difference between the inside and outside, the adjustment seat 2 slides relative to the mounting seat 1 under the action of the gas pressure, the spring 6 is stretched, and the auxiliary air holes 7 are connected to the airway 16. At this time, part of the gas passes through the secondary breathable membrane 8 and is discharged through the multiple groups of secondary breathable holes 7, and the other part of the gas passes through the main breathable membrane 4 and is discharged through the multiple groups of main breathable holes 5. The exhaust volume per unit time is increased through the secondary breathable holes 7, the exhaust pressure is effectively dispersed, and the pressure is released in time to avoid the main breathable membrane 4 from being damaged due to excessive tension. When the internal and external pressure difference returns to the normal range, the spring 6 relies on its own elastic force to drive the adjustment seat 2 to rebound and reset, covering the multiple groups of secondary breathable holes 7. At this time, the breathable valve returns to its initial state and exhausts through the multiple groups of main breathable holes 5.
