Description
Technical field
The utility model is related to ignitor, specifically a kind of ignitor air outlet valve.
Background technology
For burning torch, the air outlet valve universal architecture of lighter, as shown in Figs. 1-2 comprising needle, sealing ring, compression spring,
Valve body, pedestal and T-type rubber plug, sealing ring are tightly placed in outside needle and are close to valve interior wall, and the upper end is limited in shoulder in valve body,
Lower end is withstood by compression spring, to make to be in sealing state between valve body and needle always.There are following for the air outlet valve of above structure
Problem：After igniting, air outlet valve has been closed, but the residual air in air outlet valve also will continue to burn, and is generally needed
The fall time for wanting 5-10 seconds is not achieved the extinguishing safety requirements in 3 seconds, easily causes fire, there are security risks.
Occur the ignitor that flame can extinguish in 3 seconds after some are lighted a fire at present, can reach extinguishing safety and want
It asks.
China Patent No. 200910215376.3 discloses a kind of air outlet valve, and structure is as shown in Figure 3-4, and air outlet valve includes
Needle, sealing ring, compression spring, valve body, pedestal and T-type rubber plug, needle are in valve body, and compression spring sleeve is put in needle outer ring, sealing ring
It sets in the top of compression spring.When needle rises, sealing ring upper end is limited in shoulder in valve body, and gas is flowed out along needle inner cavity.
After needle return, the through-hole that the residual air inside needle is opened up by needle middle and upper part is flowed between valve body and needle
Channel flows upwards out.Such structure there are the shortcomings that be：High for the quality requirements of compression spring, after multi-pass operation, compression spring is compressed
Gas leakage is easy tod produce between sealing ring and needle afterwards；Needle is metalwork, due to opening hole on it, the intensity of needle is caused to become
It is weak, it is easy to be broken off, affects the service life of needle；In addition, when ignition operation, sealing ring connects with the needle positioned at through hole
It touches, since needle is metal, sealing ring is easier to be worn.Therefore, higher to each accessories manufacturing technological requirement, and quality is difficult to control
System, safety are low.
China Patent No. 200420022752.X discloses a kind of air outlet valve being used for burning torch, lighter, and structure is such as
Shown in Fig. 5-6, air outlet valve includes needle, sealing ring, compression spring, valve body, pedestal and T-type rubber plug, and valve interior wall is equipped with a lead angle
Step, needle are in valve body, and a groove is arranged on needle, and O-ring seal is located in groove, and compression spring sleeve works as valve on needle
When needle rises, by O-ring seal crimp, O-ring seal is moved up to be sealed the lead angle step of valve interior wall with valve interior wall.
Such structure there are the shortcomings that be：When each outlet operation, the whole circle of O-ring seal will slip over lead angle step, deflection
Greatly, sealing ring is damaged obviously, and operation needle has larger pause and transition in rhythm or melody sense when moving up, and often occurs that outlet is too fast or mistake
Slow phenomenon.
Utility model content
Technical problem to be solved in the utility model is to overcome the problems of the above-mentioned prior art, provides a kind of igniting
After the ignitor air outlet valve that can also extinguish in 3 seconds, keep the operation of its outlet smooth, outlet stability of flow reduces to the greatest extent
Damage to O-ring seal.
To achieve the above object, the utility model adopts the following technical scheme：Ignitor air outlet valve, including valve seat,
Needle on valve seat and valve body, valve body are sleeved on needle；
It is provided with a circle groove on the lateral wall of the needle, an O-ring seal is placed in the groove；The valve body middle and lower part
Inner wall on be provided at least one discouraged slot；
The inner cavity of the needle forms an outlet passageway being axially arranged, be provided on needle it is at least one be radially arranged it is logical
Stomata, the venthole are located at below O-ring seal and are communicated with outlet passageway；
When air outlet valve is opened, i.e., needle is in and is pulled up state, O-ring seal be located above the slot that loses heart and whole circle with
Valve interior wall sealing cooperation, gas are flowed out along outlet passageway from needle upper end from valve seat；Needle is repositioned to free state, loses heart
Residual air channel is formed between slot and corresponding local O-ring seal, the rest part of O-ring seal is still close with valve interior wall
Envelope coordinates, and the waste gas reuse venthole in needle flows through residual air channel, the existing gap between valve body top and needle outer wall
Place's discharge.
Residual air can be discharged automatically after igniting for the utility model, ensure that flame extinguishes in 3 seconds, eliminate
The security risk that ember combustion zone comes.When the utility model outlet operates, it is only necessary to which the part of O-ring seal is slipped over discouraged slot
Sealing can be realized, O-ring seal and the contact area of discouraged slot are small, and deflection is small, are damaged to O-ring seal small；Due to O-shaped
Sealed ring deformation amount is small, smooth, outlet stability of flow when operation needle moves up.
As the supplement of above-mentioned technical proposal, the valve interior wall forms a circle step, the O-ring seal always with
Valve body vertical inner wall cooperation above step.Since O-ring seal coordinates with valve body vertical inner wall always, operated in outlet
When, O-ring seal resistance smaller, the damage smaller being subject to.
Bottom edge as the supplement of above-mentioned technical proposal, the slot that loses heart is flushed with the bottom surface of step, and valve body is facilitated to process.
As the supplement of above-mentioned technical proposal, the width of the discouraged slot is 0.3-1.5mm（Preferably 0.6-0.8mm）,
Very little is damaged to O-ring seal under the premise of not influencing to lose heart.
As the supplement of above-mentioned technical proposal, the groove is located on the lateral wall in the middle part of needle.From overall consideration, this
Position is appropriate to set groove.
As the supplement of above-mentioned technical proposal, the discouraged slot has multiple, preferably 2-4, in circumferentially distributed.
As the supplement of above-mentioned technical proposal, the bottom of the needle is equipped with a T-type rubber plug, the bottom of valve seat be provided with one into
Stomata；When needle is repositioned to free state, T-type rubber plug cover lives in stomata, prevents air inlet.
As the supplement of above-mentioned technical proposal, a ring type seal is cased on the outer wall of the seat bottom portion.Utilize annular
Sealing ring makes valve seat outer wall be tightly connected with oil groove wall.
As the supplement of above-mentioned technical proposal, the material of the valve body is plastics, as long as processing discouraged slot i.e. when injection molding
Can, keep valve body easy to process；May be metal, such as zinc, aluminium.
As the supplement of above-mentioned technical proposal, a pressure being located above O-ring seal is cased on the needle in valve body
Spring.Needle is set to be repositioned to free state from gaseity is gone out using compression spring.
The utility model has the advantage that as follows：When the utility model outlet operates, it is only necessary to by O-ring seal
Part slips over discouraged slot and sealing can be realized, and O-ring seal and the contact area of discouraged slot are small, and deflection is small, to O-ring seal
It damages small；Smooth, outlet stability of flow when operation needle moves up, it is safe.
