Description
Technical field
The utility model relates to a kind of lighter, relates in particular to a kind of piezoelectric ceramic ignitor of falling the pressure type of lighter.
Background technology
Common piezoelectric ceramic ignitor uses two potteries, and every pottery all has the branch of both positive and negative polarity, when assembling, all want anodal to positive pole, the copper fork is set in order to connect lead as positive pole between two piezoelectric ceramics, after being connected to push rod spring with electric-conductor, the nut of one end of negative pole by the bottom be connected to the piezoelectricity cap, and other end negative pole is by holding nail hitting, and hammer is connected to the piezoelectricity cap.This piezoelectric ceramics igniter assembling is very complicated, and cost is very high. and another kind of piezoelectrics from external import, not only the very high but also output voltage of price is very low not too is fit to domestic lighter. also have the piezoelectrics of a pottery of a kind of use of domestic nearest exploitation, what it adopted is the big pottery of ceramic volumetric that uses in more common two ceramic igniters, and this pottery one side price height, the technology and equipment of this bulky pottery of domestic production is all immature on the other hand, and its structure neither be quite reasonable, so do not reach the requirement of quality always, lighting rate is extremely low. applied for that if any the people name is called a kind of Chinese utility model patent of igniter of lighter, the patent No. is 200720192740.5, the day for announcing is on December 03rd, 2008, notification number is CN201159474, this formerly utility model a kind of igniter of lighter is disclosed, comprise the copper anvil, piezoelectrics and piezoelectricity cap, wherein, the copper anvil is as an electrode of igniter, on the piezoelectrics sidewall male part is set, be provided with a conductive pole that exposes in this male part and as another electrode of igniter, this formerly utility model by conductive pole is set in male part, make an electrode of exporting by piezoelectric ceramics one end in the igniter can pass through this conductive pole, metal seesaw and conduct to the mouth of air-out needle, and a utmost point of copper anvil can be directly conducts near the air-out needle mouth by conducting strip in the igniter, therefore need not to draw lead from the sidewall of piezoelectrics, make igniter be easy to processing, assembling, simultaneously, produce between the two poles of the earth of electric spark, it is the end fixed distance of air-out needle mouth and conducting strip, therefore, can guarantee the lighter stable ignition.But this formerly utility model patent also have following defective: directly bump contact between piezoelectric ceramics and the copper anvil, can not guarantee that piezoelectric ceramics contacts with the copper anvil closely effectively, simultaneously, directly contact mutually when bump, do not have bolster between piezoelectric ceramics and the copper anvil, cause bump to break and wear and tear easily, be unfavorable for prolonging the ceramic discharge time, be unfavorable for improving the service life of piezoelectric ceramics, reduced the lighting rate of igniter.
Summary of the invention
The utility model can not effectively prolong piezoelectric ceramics discharge time at existing in the prior art, can not effectively improve the service life of piezoelectric ceramics, can not effectively improve the technological deficiency of the lighting rate of igniter, be provided a kind of piezoelectric ceramics discharge time of effectively prolonging, the service life of piezoelectric ceramics can be effectively improved, a kind of piezoelectric ceramics of falling pressure type igniter of igniter can be effectively improved.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of piezoelectric ceramic ignitor of falling the pressure type, comprise piezoelectricity cap, piezoelectrics, conduction anvil, the conduction anvil is as an electrode output point of igniter, be provided with hammer in the piezoelectrics, hold nail hitting, piezoelectric ceramics, be provided with compression spring between piezoelectricity cap and the hammer, the hammer below is provided with back-moving spring, piezoelectrics are provided with electric-conductor, after described piezoelectricity cap presses down, electric-conductor and back-moving spring and piezoelectricity cap are conducted and as another electrode output point of igniter, are provided with the buffering sheet metal between described piezoelectric ceramics and the conduction anvil.
As preferably, the top of described buffering sheet metal is provided with boss, and the below is provided with recess.
As preferably, described piezoelectrics are provided with the injecting glue mouth of a river, injecting glue mouth of a river injection ring epoxy resins glue, and the gap between piezoelectric ceramics and the piezoelectrics is filled up in cooling.
As preferably, described piezoelectrics are provided with brace table, are provided with draw-in groove in the brace table, and electric-conductor is located in the draw-in groove.
As preferably, described conduction anvil is provided with leg-of-mutton flange, correspondingly is provided with hole clipping on the sidewall of the bottom of piezoelectrics, and flange is clamp-oned in the hole clipping.
The buffering sheet metal of this programme is avoided directly clashing between piezoelectric ceramics and the conduction anvil, guarantees that piezoelectric ceramics contacts closely effectively with the conduction anvil, helps prolonging the ceramic discharge time, has reduced the lighting rate of igniter.Simultaneously, not directly contact mutually is not easy to cause bump to break and wear and tear when bump, helps improving the service life of piezoelectric ceramics.
, be easier to automatic production line production, and steady quality, the piezoelectric ceramics igniter that lighting rate is high.
