Air tube middle and upper part outer wall pocketed springs, the lower end of the spring is located on the support collar, the inner chamber top of the valve casing with
Sealing ring is provided between air-out needle, the top of the spring is contacted on the sealing ring.By stretching assembly by air-out needle to
Pull-up so that T-shaped sealing-plug is separated with the positioning spur, realizes gas passage insertion；Stretching assembly resets, in the work of spring
Under, the T-shaped sealing-plug is held out against in the positioning spur.
Constant current microporous barrier is arranged on the inlet channel of valve seat bottom, the constant current microporous barrier is positioned by plastic sheath,
The plastic sheath is plugged on the inner chamber of the valve seat bottom and contacts the constant current microporous barrier.The technological deficiency of presence is：Due to
It is grafting between the inner chamber of plastic sheath and valve seat bottom, is interference fitted each other, larger mating force ability is needed during assembling
Realize positioning；Furthermore, such as there is larger vibration situations such as assembling and transportation, the mode that grafting is positioned easily receives outer
Boundary vibrates and causes to loosen, and reliability is poor, the positioning of constant current microporous barrier is influenceed, so as to influence the quality of air outlet valve.
The content of the invention
In order to overcome the shortcomings of the constant current microporous barrier of existing exhaust valve for lighter easily loosen, reliability it is poor, this practicality
It is new to be prevented effectively from the cigarette lighter constant-current assembly apparatus that constant current microporous barrier loosens, reliability is good there is provided a kind of.
The utility model solves the technical scheme that its technical problem used：
It is in the middle part of a kind of cigarette lighter constant-current assembly apparatus, including shell, constant current microporous barrier and hollow fixed cover, the shell
The constant current microporous barrier is arranged on inlet channel, the inlet channel, the hollow fixed cover is located at the shell inner cavity, described
Ring is stretched in the lower end of shell provided with interior, the hollow fixed cover bottom, which is located in described, stretches on ring, and the hollow fixed cover is contacted
In the bottom surface of the constant current microporous barrier.
Further, gap is provided between the hollow fixed cover and the shell inner cavity.It is of course also possible to bonded to each other.
Further, the inner chamber of the shell of the top of the constant current microporous barrier sets flow to control step.
The upper surface of the hollow fixed cover is provided with Flow-rate adjustment step, the Flow-rate adjustment step and the inlet channel
Connect.
Scheme of the present utility model, has abandoned existing grafting positioning method, employs interior ring of stretching and realizes positioning, even if
There is the occasion of larger vibration in situations such as assembling and transportation, effect avoids constant current microporous barrier from loosening, reliability is good, effectively protects
The quality stability of air outlet valve is demonstrate,proved.
The beneficial effects of the utility model are mainly manifested in：Be prevented effectively from constant current microporous barrier loosen, reliability it is good.
