Description
(1) technical field
The utility model relates to a kind of exhaust valve for lighter.
(2) background technology
With reference to Fig. 1, the air outlet valve structure of lighter is normally so at present: it comprises thread bush 1 with through hole and the valve seat 2 with through hole, and the front portion of valve seat 2 closely is socketed on the rear portion of thread bush 1, and the through hole of thread bush and valve seat is formed container cavity; One rear portion with air-out needle 4 of outlet chamber 3 is stretched in the container cavity, pass through hermetic seal between the thread bush 1 at place and the air-out needle 4, the air-out needle 4 outer stage clips 5 that are with, and offer air admission hole 6 on its wall, its end has plugging block 7, there is shoulder 8 at the rear portion of valve seat through-hole, and plugging block 7 offsets with this shoulder 8, forms sealing surface between the two, the inwall that the outer wall of air-out needle, thread bush and valve are sat surrounds airtight chamber 9, and the air admission hole 6 on the air-out needle is communicated with the outlet chamber 3 of airtight chamber 9 and air-out needle.
During use, upwards pull up air-out needle 4, no longer sealing between the shoulder 8 of plugging block 7 and valve seat through-hole, the combustion gas of lighter just can enter in the closed chamber 9, and then enters into the outlet chamber 3 of air-out needle by the air admission hole 6 of air-out needle, again from outlet chamber 3 outflows.
In this structure, valve seat 2 is socket with thread bush 1, and its sealing reliability is poor, and service time, some the combustion gas leakage phenomenon will occur a little for a long time; And in order to guarantee sealing between the two, require between the two that contact-making surface carries out Precision Machining, complicated manufacture craft.
(3) summary of the invention
For the deficiency that overcomes exhaust valve for lighter sealing reliability deficiency in the prior art, makes processed complex, the utility model provides a kind of good seal performance, makes exhaust valve for lighter easy to process.
The technical scheme in the invention for solving the technical problem is: a kind of exhaust valve for lighter, comprise air-out needle with outlet chamber, described air-out needle is with stage clip outward, offer air admission hole on the wall of this air-out needle, end has plugging block, comprise that also one has the valve pocket of through hole, the rear portion of the inwall of described valve pocket has crossette, the rear portion of described air-out needle is placed in the through hole of described valve pocket slidably, pass through hermetic seal between the valve pocket at place and the air-out needle, hermetic seal between described plugging block and the described crossette, the outer wall of described air-out needle and the inwall of valve pocket surround airtight chamber, and the air admission hole on the described air-out needle is communicated with the outlet chamber of described airtight chamber and described air-out needle.
Further, also have air inlet pipe in the through hole of described valve pocket, described air inlet pipe is located on the crossette of described valve sleeving inner wall, and seals by sealing ring; Described air inlet pipe front end is a shiny surface, and described shiny surface and described plugging block offset, and form sealing surface between the two.
Further, the shoulder that projection is arranged on the outer wall of described air-out needle, described valve pocket front end is useful on the collar of the described airtight chamber of sealing, and described collar has the shoulder to the through hole projection of valve pocket, and described stage clip is placed between the shoulder of the shoulder of air-out needle and collar.
Further, between the shoulder of described stage clip and described collar seal washer is arranged.
Further, the lower end of described valve pocket outer wall is provided with the O RunddichtringO.
During use, upwards pull up air-out needle, plugging block no longer seals closed chamber, and the combustion gas of lighter just can enter in the closed chamber, and then enters into the outlet chamber of air-out needle by the air admission hole of air-out needle, flows out from outlet chamber again.
The beneficial effects of the utility model are: 1. valve seat of the prior art and thread bush one are turned to valve pocket, avoided sealing unreliable problem between the two in the prior art.2. only need one-body molded valve pocket get final product when making, do not consider the accuracy problem of valve seat and thread bush contact-making surface in the prior art at needs, making is processed easy.3. the steady and smooth in order to guarantee that combustion gas is given vent to anger, experience shows, when the gas inlet of valve seat adopts copper product in the prior art combustion gas give vent to anger more steadily, smooth and easy, so then whole valve seat can only be made copper product, thereby the manufacturing cost of air outlet valve is higher.When the utility model was provided with air inlet pipe, air inlet pipe was positioned at the gas inlet place of valve seat, was getting final product of copper product so only need air inlet pipe, and whole valve pocket can adopt plastic material, has saved production cost greatly.

Fig. 1 is the cutaway view of exhaust valve for lighter in the prior art.
Fig. 2 is the cutaway view of embodiment one described exhaust valve for lighter.
Fig. 3 is the cutaway view of embodiment two described exhaust valve for lighter.
Fig. 4 is the exploded view of embodiment two described exhaust valve for lighter.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment one
With reference to Fig. 2, a kind of exhaust valve for lighter, comprise air-out needle 4 with outlet chamber 3, offer air admission hole 6 on the wall of this air-out needle 4, end has plugging block 7 (elastomeric material), comprise that also one has the valve pocket 10 of through hole, the rear portion of the inwall of described valve pocket 10 has crossette 8, the lower end of described valve pocket outer wall is provided with O RunddichtringO 11, the rear portion of described air-out needle 4 is placed in the through hole of described valve pocket 10 slidably, pass through hermetic seal between the valve pocket 10 at place and the air-out needle 4, hermetic seal between described plugging block 7 and the described crossette 8, the outer wall of described air-out needle and the inwall of valve pocket surround airtight chamber 9, and the air admission hole 6 on the described air-out needle is communicated with the outlet chamber 3 of described airtight chamber 9 and described air-out needle.
The shoulder 12 that projection is arranged on the outer wall of described air-out needle 4, described valve pocket 10 front ends are useful on the collar 13 of the described airtight chamber of sealing, described collar has the shoulder 14 to the through hole projection of valve pocket, be with stage clip 5 between the shoulder 12 of air-out needle and the shoulder 14 of collar, between the shoulder 14 of described stage clip 5 and described collar seal washer 15 arranged.
During use, upwards pull up air-out needle 4, no longer sealing between the shoulder 8 of plugging block 7 and valve seat through-hole, the combustion gas of lighter just can enter in the closed chamber 9, and then enters into the outlet chamber 3 of air-out needle by the air admission hole 6 of air-out needle, again from outlet chamber 3 outflows.
Embodiment two
