Dynamic, make the first seal 4 prop up filter fixed component 3 and form the sealing to IVC cage box ventilation mouth.
Improve further, also include: seal 7 be arranged at filter fixed component 3 inwall and reset push rod 6 second it
Between, and adjacent with the face that filter fixed component 3 contacts with the first seal 4.
Improving further, also including: the 3rd seal 8, the 3rd seal 8 is two, is respectively arranged at cage box 2 and filters
Between device 1, and between cage box 2 and filter fixed component 3.
Wherein, elasticity reset device 5 is back-moving spring.
Wherein, the second seal 7 is arranged in the groove of filter fixed component 3 inwall.
Wherein, filter 1 and filter fixed component 3 are sealed even by the silk dentification of filter fixed component 3 inwall
Connect.
Wherein, the second seal 7 is sealing ring, and the 3rd seal 8 is sealing gasket.
Wherein, back-moving spring near filter fixed component 3 one end near 6 first one end internal diameters of reset push rod by
Cumulative greatly.
Having IVC cage box of the present utility model when being arranged on cage, the elastic ventilation base member on cage props up reset
Push rod (first 6.1), reset push rod (first 6.1) elasticity of compression resetting means, drive reset push rod (second simultaneously
6.2) move to cage box direction, make the first seal separate with filter fixed component, thus air-flow can circulate.Take from cage
When lower, promote reset push rod (first 6.1) by the elastic force of elasticity reset device, drive reset push rod (second 6.2) to
Move away from cage box direction, make the first seal prop up filter fixed component and form the sealing to IVC cage box ventilation mouth.Have
IVC cage box of the present utility model can realize mouth automatic-sealed of taking a breath when departing from cage.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the IVC cage box ventilation mouth structure that the utility model provides, comprising: filter 1 is arranged at cage
Box 2 is taken a breath at mouth, and filter fixed component 3 is arranged at outside cage box ventilation mouth, and filter 1 and filter fixed component 3 seal
It is fixedly connected on cage box 2 to take a breath and form clamping to cage box wall at mouth；
Reset push rod 6 includes first and second, and second of reset push rod 6 is that filter 1 air inlet can be inserted in one end
Mouthful, the other end can insert the hollow structure of IVC system cage elastic ventilation base member 9, second of reset push rod 6 and filter
1 connects formation gas channel, and first of reset push rod 6 is positioned on second of reset push rod 6, reset push rod in the present embodiment
The direction that first of 6 is perpendicular to second of reset push rod 6 arranges (being i.e. perpendicular to described gas channel), reset push rod 6
