On be respectively provided with the first outer 312 and the second outer 313 extended horizontally outward, the sealing of the second outer 313 is fixed on the top of shell 1
On portion's inner surface, the first seal 4 is fixed on the bottom of the first outer 312；Coil 32 is set in the outside wall surface of recessed portion 311
It goes up and is located between the first outer 312 and the second outer 313, bottom is overlapped on the first outer 312.
As shown in Fig. 2, the first seal 4 is the first groove being provided on 312 bottom of the first outer, it is preferably annular
Slot.
As shown in Fig. 2, Fig. 6 and Fig. 7, movable part 6 is preferably plate, and is made of magnetic material, for example, magnet steel or
The lower section in shell 1 and being located at driving mechanism 3 is arranged in magnet, plate, and the second seal 5 is fixed on the top surface of plate
On.As shown in fig. 6, plate is arranged in shell 1 by resetting-mechanism, resetting-mechanism includes that four be arranged in below plate consolidate
Determine part 8 and four elastomeric elements 9, fixing piece 8 is preferably fixed plate, and elastomeric element 9 is preferably spring, and spring is arranged in fixed plate
Between plate, spring can apply the pulling force for being directed away from 4 direction of the first seal to movable part 6, convenient for the second sealing
Body 5 is detached from from the first seal 4, resets to initial state.
The edge of plate has towards horizontal-extending four extensions 61 of 1 inner wall of shell, it is preferable that four extensions
61 are evenly distributed on plate；Accordingly, above-mentioned guide frame be provided on 1 inner wall of shell with extension 61 one by one
Corresponding and vertically extending guide groove 11, extension 61 are respectively protruding into a guide groove 11, and elastomeric element 9 is located at guide groove 11
Interior, when hot-wire coil 32 applies the electromagnetic force of vertical motion to plate, guide groove 11 can guide plate vertically to do straight line
Movement, convenient for 5 face of the second seal to be caught in the first seal 4.
As shown in fig. 6, the second seal 5 is prominent to be molded over can seal on plate top surface and be caught in the first groove
The first interior elastic sealed body, such as elastic seal ring.Above-mentioned supporter 31, the first groove, the first elastic sealed body and
The first cavity 7 is surrounded between plate, the first waterproof ventilated membrane 2 is located in the first cavity 7.
In addition, opening up first at the position of movable part 6 being located in the second seal 5 as shown in Fig. 6, Fig. 7 and Fig. 8
Through-hole 62, being located on ipsilateral surface with the second seal 5 for first through hole 62 are fixed with seal first through hole 62 second
Waterproof ventilated membrane 63；Accordingly, bracket 33, such as cross brace 33, cross brace 33 are set on the bottom opening of recessed portion 311
The bottom opening of recessed portion 311 is divided into four second channels, in the bottom setting second of the crossover location of cross brace 33
Lancet and means 64, such as protrusion, the spine ends of the second lancet and means 64 towards the second waterproof ventilated membrane 63, and with the second waterproof
Gap needed for being reserved between ventilated membrane 63.In addition, the partition with channel is formed in the bottom surface of first through hole 62,
It prevents the intracorporal component of case from protruding into the through-hole, damages the second waterproof ventilated membrane 63.
First moisture detector 101 is arranged in the external world, for detecting the humidity of gas in external environment, the second Humidity Detection
Device 102 is arranged on the bottom of movable part 6, such as the humidity by glue sticking, for gas in detection box；Controller root
According to the detection data of the first moisture detector 101 and the second moisture detector 102, opening or closing for driving mechanism 3 is controlled.Separately
Outside, the fairlead passed through for the wire seal of the first moisture detector 101 is also opened up on shell 1, electric wire passes through fairlead again
In the threading hole opened up into the side wall of 1 inner cavity of shell；Meanwhile second the electric wire of moisture detector 102 be also threaded through threading hole
Interior, final two electric wires are installed in the inside of cabinet.First moisture detector 101 and the second moisture detector 102 are all made of
Existing humidity sensor.
The dynamic seal structure of this embodiment is mounted on balance vent valve, then balance vent valve is mounted on cabinet
On mounting surface, dynamic seal structure is located at the inside of cabinet, when the first humidity sensor detects that extraneous humidity is X1, second
Humidity sensor detects that the humidity of box house is X2, and the psychrometric difference of gas is Δ X=in the humidity and cabinet of ambient atmos
X1-X2.Under normal condition, the second seal 5 is in far from the first seal 4, the first waterproof ventilated membrane 2 with box house
Connected state, Δ X is in preset value at this time；When the X1 variation in external environment, when Δ X is higher or lower than preset value, control
Device is controlled and is powered to the coil 32 in driving mechanism 3 according to this information, and the coil 32 after energization generates electromagnetic force, with driving plate
Block drives the first elastic dense body thereon to move towards the first groove direction, and the extension 61 of plate is transported upwards in guide groove
Dynamic, spring is stretched and storage energy, so that the sealing of the first elastic sealed body is caught in the first groove and seals the first cavity 7,
It realizes between the first waterproof ventilated membrane 2 and box house in isolation, so that it may extraneous vapor be stopped to enter cabinet
The vapor of inside or box house flows to the external world by the first waterproof ventilated membrane 2, so that the humidity of case vivo environment
It is always held at steady state, it is ensured that the intracorporal element of case can normally be run.When Δ X reaches preset value again, and it is in
When stable state, controller controls to the logical reversed electricity of coil 32 or stops being powered, and coil 32 applies direction to the second seal 5
The power in separate first seal, 4 direction does not generate electromagnetic force to the second seal 5, under the reset response of extension spring,
Spring releases energy, to drive the second seal 5 to be directed away from the movement of 4 direction of the first seal, so that the second seal 5 resets
To initial state, spring is again at the compressive state of starting, to complete according to humidity, to adjust the dynamic of balance vent valve
Seal process.
In addition, generating huge pressure in cabinet, air pressure is by partition when other abnormal accidents occur in cabinet
Channel apply outside active force to the second waterproof ventilated membrane 63 so that the second waterproof ventilated membrane 63 is towards the second lancet and means
The bending of 64 directions, the second lancet and means 64 just wear out the second waterproof ventilated membrane 63, no matter the second seal 5 and first close at this time
It seals body 4 and is in separation or sealing state, air pressure, which enters in the first cavity 7, applies outside active force to the first waterproof ventilated membrane 2,
So that the first lancet and means in balance vent valve poke the first waterproof ventilated membrane 2, it will be able to release the intracorporal high pressure of case
It runs out, so that the intracorporal air pressure of case is consistent with extraneous air pressure, prevents from that explosion phenomenon occurs in cabinet.
