DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] Refer to the attached Figure 1 -Attached Figure 5 The micro-pressure air-permeable valve provided by the utility model comprises:

[0031] The micro-pressure breathable valve body 1 is configured as a cylindrical structure;

[0032] A top cover 2, which is arranged on the top of the micro-pressure air-permeable valve body 1;

[0033] A plurality of vent holes 3 are provided on the outer side of the top cover 2. The design of the plurality of vent holes 3 allows ventilation inside and outside the micro-pressure vent valve body 1.

[0034] A closing mechanism, which is arranged inside the micro-pressure air-permeable valve body 1 and is used to open and close the ventilation work;

[0035] In this embodiment, the user installs the micro-pressure breathable valve body 1 at the exhaust position of the product through the threaded groove 15, and the breathable work starts when the internal and external pressure of the micro-pressure breathable valve body 1 reaches a certain level;

[0036] Among them, in order to achieve the purpose of exhaust and inhalation, the present device is implemented by the following technical scheme: the closing mechanism includes a pressure silicone plug 5, the pressure silicone plug 5 is arranged inside the micro-pressure breathable valve body 1, the pressure silicone plug 5 is set to a triangular structure, a pressure plate 6 is embedded in the micro-pressure breathable valve body 1, and the pressure plate 6 is fixedly connected to the bottom of the pressure silicone plug 5, the closing mechanism also includes a pressure spring 7, the pressure spring 7 is embedded in the micro-pressure breathable valve body 1, the pressure spring 7 is fixedly connected to the bottom of the pressure plate 6, a fixing ring 8 is fixedly embedded at the bottom of the inner side of the micro-pressure breathable valve body 1, and the fixing ring 8 is fixedly arranged at the bottom of the pressure spring 7, a connecting ring 10 is embedded in the micro-pressure breathable valve body 1, and the connecting ring 10 is arranged inside the top cover 2 before being fixed, and a waterproof breathable membrane 11 is fixedly embedded inside the connecting ring 10, and two side plates 12 are fixedly connected to the top of the fixing ring 8, and the two side plates 12 are both sleeved on the outside of the pressure spring 7, and the two side plates 12 are used to block the pressure spring 7;

[0037] The device controls the closing mechanism to exhaust and inhale the air through micro-pressure. When the internal air pressure value of the device is small, the pressure silicone plug 5 and the pressure spring 7 will not move, so that the exhaust and inhalation work will not be performed. When the internal air pressure value of the device is large, the pressure silicone plug and the pressure spring 7 are in a compressed state, so that the micro-pressure breathable valve body 1 is opened, thereby performing the work of exhausting the inside and outside. This function is to block the air circulation inside and outside when the pressure difference between the inside and outside of the device is balanced or very small, thereby reducing the moisture in the air;

[0038] Among them, in order to achieve the purpose of installation, the device is implemented by adopting the following technical scheme: two positioning blocks 13 are fixedly connected to the bottom of the pressure silicone plug 5, two positioning grooves 14 are opened on the top of the pressure plate 6, the two positioning blocks 13 are matched with the two positioning grooves 14 respectively, and a threaded groove 15 is opened on the outside of the micro-pressure air permeable valve body 1.

[0039] The use process of the utility model is as follows: the user installs the micro-pressure breathable valve body 1 at the exhaust position of the product through the threaded groove 15. The ventilation work starts when the internal and external pressures of the micro-pressure breathable valve body 1 reach a certain level. The device controls the closing mechanism through micro-pressure to exhaust and inhale the air. When the internal air pressure value of the device is small, the pressure silicone plug 5 and the pressure spring 7 will not move, thereby not playing the role of exhaust and inhalation. When the internal air pressure value of the device is large, the pressure silicone plug and the pressure spring 7 are in a compressed state, so that the micro-pressure breathable valve body 1 opens, thereby playing the role of exhausting the inside and outside. This function is to block the internal and external air circulation when the internal and external pressure difference of the equipment is balanced or very small, thereby reducing the moisture in the air.

[0040] The above is only a preferred embodiment of the utility model. Any person skilled in the art may modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
