Valve deck is packed into body cavity and deviates from contact pin side, and valve deck tip edge is bonded with sealing ring；
It is equipped with through-hole among sealing ring, is equipped with fluid stopping column among valve deck top, the fluid stopping column is bonded and seals with sealing ring
It closes residence and states through-hole；
Clearance groove is equipped between the fluid stopping column and valve deck edge of valve deck；Valve deck is equipped with air inlet, air inlet and the sky
Slot communicates.
Further, the head of the contact pin is equipped with an olecranon.
Further, the interior step of body cavity is equipped with groove, and sealing ring edge has flanging and is pressed in the groove
In.
Further, the convex buckle position matched and recessed button bit are respectively equipped on valve deck lateral wall and valve body inner sidewall.
Further, further include a protective cover for being set in outside contact pin.
Further, the material of sealing ring is silica gel.
Further, air inlet is arranged in valve deck bottom end.
Further, contact pin is structure as a whole with valve body.
The advantages of the utility model:
1) part use is greatly decreased in the check valve, the deficiency of low efficiency caused by reducing because of the cooperation of more parts；With air inlet
Flow is big, advantage at low cost.
2) external energy, energy conservation and environmental protection are not necessarily to.
3) it is directly inserted in cleaning solution bottle and uses, it is easy to use, without additional adapter tube.
Detailed description of the invention
Fig. 1 is the structure composition schematic diagram of the utility model.
Specific embodiment
Below with reference to specific drawings and examples, the utility model is described in further detail.
As shown in Figure 1, the utility model proposes a kind of one-way ventilating valve cannot be adopted since volume requirement is smaller
With common camber of spring dynamic structure, but use the structure of sealing ring and the cooperation of valve deck fluid stopping column；The one-way ventilating
Valve includes contact pin 1, valve body 3, flexible sealing ring 4, valve deck 5；
It is equipped with air flue 101 in the contact pin 1, is equipped with inner cavity 301 in valve body 3；The root of contact pin 1 is connected with 3 one end of valve body,
Air flue 101 in contact pin 1 is communicated with body cavity 301；
Interior step is equipped among 3 inner cavity 301 of valve body, sealing ring 4 is pressed on the interior step of body cavity 301；
More preferably, the interior step of body cavity 301 is equipped with groove 302, and 4 edge of sealing ring has flanging and is pressed in described
In groove 302, valve deck 5 is packed into body cavity 301 by tight fit and deviates from 1 side of contact pin, 5 tip edge of valve deck and sealing ring 4
Fitting；
It is equipped with through-hole 401 among sealing ring 4, fluid stopping column 501, the fluid stopping column 501 and sealing are equipped among 5 top of valve deck
Circle 4 is bonded and closes the through-hole 401；
Clearance groove 502 is equipped between 5 edge of fluid stopping column 501 and valve deck of valve deck 5；Valve deck 5 is equipped with air inlet 6, air inlet
Mouth 6 is communicated with the clearance groove 502；Air inlet 6 is preferably provided at 5 bottom end of valve deck；
More preferably, the convex buckle position 503 matched and recessed button bit are respectively equipped on 3 inner sidewall of 5 lateral wall of valve deck and valve body
303；
The material of sealing ring 4 is preferably silica gel, and elasticity and leakproofness are good；
The one-way ventilating valve can be inserted in liquid bottles, and when liquid bottles do not have drawing liquid, liquid bottles external and internal pressure is consistent, sealing
It encloses 4 intermediate positions to be bonded with fluid stopping column 501, fluid stopping column 501 encloses the through-hole 401 among sealing ring 4, therefore in liquid bottles
Liquid will not be revealed；
When liquid bottles carry out drawing liquid, the liquid pressure in the bottle is less than bottle external pressure, outside bottle under atmospheric pressure effect, sealing
4 middle part of circle is detached from fluid stopping column 501, and the outer air of liquid bottles enters body cavity 301 from 4 intermediate throughholes 401 of sealing ring, continues through
Contact pin 1 enters in liquid bottles；To guarantee that liquid forms the fluid pressure of setting in liquid bottles and flow is discharged；
The head of the contact pin 1 is equipped with an olecranon 102 as gas outlet, which can prevent contact pin to be inserted into liquid
When bottle, the residue that liquid bottles are fallen enters the air flue 101 in contact pin 1.
