Embodiment 1
[0047] This embodiment provides a dynamic sealing structure applied to a balanced breathable valve, such as figure 1 , figure 2 and image 3 As shown, it includes a housing 1, a first sealing body 4, a second sealing body 5, a movable part 6, a driving mechanism 3, a first humidity detector 101, a second humidity detector 102, a reset mechanism, a guide structure and a controller .
[0048] The housing 1 has a top opening and an inner cavity. Such as figure 2 As shown, the drive mechanism 3 includes a support body 31 and a coil 32. The support body 31 is sealed and fixed on the inner surface of the top opening of the housing 1 and wound on the side wall of the first waterproof and gas-permeable membrane 2. The top of the support body 31 has a suitable The concave part 311 embedded in the first waterproof gas-permeable membrane 2, that is, the first waterproof gas-permeable membrane 2 extends into the concave part 311 through the top opening of the housing 1, the bottom o...

The invention discloses a dynamic sealing structure applied to a balance breather valve. The dynamic sealing structure comprises a first sealing body, a second sealing body and a driving mechanism; the first sealing body is arranged on the side wall of a first water-resistible and breathable film at the bottom of the balance breather valve in a sealed and winding manner; the second sealing body and the first sealing body are oppositely arranged and define a first cavity, and the first water-resistible and breathable film is located in the first cavity; and the driving mechanism is used for driving the second sealing body to move in the direction being close to or far away from the first sealing body, so that the second sealing body is in sealed fit with the first sealing body or breaks away from the first sealing body. When the balance breather valve with the sealing structure is installed on the installation face of a box, abnormal working conditions occur, and the humidity of external air is higher than or lower than the humidity of the interior of the box, the driving mechanism drives the second sealing body to move to the first sealing body and is in sealed fit with the first sealing body, the first water-resistible and breathable film is sealed into the first cavity, and components in the box can run under the needed constant humidity conditions.
Description
technical field [0001] The invention relates to the technical field of a balanced breathable valve, in particular to a dynamic sealing structure applied to a balanced breathable valve. Background technique [0002] The balance vent valve can be applied to electric vehicle battery pack boxes, or high-pressure control boxes, or some sealed boxes that require high air pressure or humidity. Especially in the new energy auto parts pack battery pack, the balance vent valve is installed on the installation surface of the battery pack product. The vent valve can balance the internal and external air pressure balance when the internal pressure of the installation box changes, and the internal air pressure rises sharply. , the internal pressure can be released; at the same time, the breather valve plays the role of sealing and isolating the inside of the installation box from the outside world. [0003] The structure of the existing balance breathable valve is mostly as the balance b...
