Abstract

The utility model relates to an electronic cigarette with an air switch, which comprises a filter tip, a cigarette cavity and a cigarette rod, wherein the filter tip is inserted into the cigarette cavity, the inner wall of the cigarette cavity is provided with an air inlet, a heating wire is arranged in the cigarette cavity and is provided with a blocking ring which prevents tobacco juice from leaking outwards, the cigarette cavity and the cigarette rod are connected by screw threads, the other end of the cigarette rod is provided with a luminous device, and an electronic circuit board and a battery are arranged in the cigarette rod; the electronic cigarette also comprises an air switch which comprises an outer shell, a copper key assembly, a silica gel gasket, a lower mould, a copper core pointer, a pointer corner bracket, a PCBA board and a spacing piece which are orderly arrayed, the copper core pointer passes through the lower mould and is connected with the silica gel gasket, and the pointer corner frame corresponding to the copper core pointer is fixed on the PCBA board and is respectively connected with a positive pole and a negative pole of the battery. When a user breathes in, a copper pole and a copper piece pointer assembly move towards a breathing direction, the copper piece pointer is communicated with a circuit which is in contact with the copper piece foot frame on the PBCA board, and contrariwise, the circuit is switched off. The utility model has the advantages that the use times are increased to 300 to 500 thousand times, the sensitivity of the air switch is synchronously increased above 50 percent, the structure is simple, and the easiness of the integral installation is increased.

Description

The electronic cigarette of band air switch

Technical field

The utility model relates to a kind of electronic cigarette, particularly a kind of electronic cigarette with band air switch of smoking cessation function.

Background technology

Cigarette extensively is subjected to especially liking of menfolk of people as a kind of preference.Yet the tar in the cigarette is harmful to the health of human body, and it is carcinogens that tens of kinds of compositions are wherein arranged, and the harm that secondary smoking causes the non-smoker is very big also.Therefore the regulation that no smoking is all arranged in public places.But, want to accomplish that non-smoking is very very difficult thing for a smoker.So, a lot of cigarette substitutes has just appearred on the market, as, Chinese patent, the disclosed a kind of harmful tar that do not contain of ZL03211903.8, the non-combustible electronic atomized cigarette that only contains nicotine (nicotine), be characterized in, the pneumatic sensor that constitutes the tail end cigarette holder place setting of cigarette is connected to through signal transmission wire and is used to start the atomizer high-frequency generator that joins through feed pipe and storage nicotine solution on the circuit board, the high-frequency generator that band connects in the front shell of revolving mouth connects counting circuit and display screen, and the circuit board in the front shell is equipped with the end shield of light emitting diode to the cigarette front end through battery and spring.This electronic cigarette complex structure, the cost height because of the long-time heating of heating wire makes its service life short, is unfavorable for applying during use.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of popularization simple in structure, easy, cost is low and long service life, access times reach the electronic cigarette of the band air switch of 30-50 ten thousand.

The purpose of this utility model is achieved by following technical proposals:

The electronic cigarette of band air switch of the present utility model comprises filter tip, smoke chamber and tobacco rod constitute, filter tip inserts smoke chamber, have air admission hole on the smoke chamber inwall, smoke chamber built-in heating silk, and be provided with and prevent the tobacco juice back-up ring that leaks outside, smoke chamber and tobacco rod are by being threaded togather, the other end at tobacco rod, have one to be used to indicate photophore, electronic circuit board and battery are arranged in the tobacco rod, it is characterized in that also comprising air switch, described air switch is by shell, the copper key asembly, silicone gasket, counterdie, copper core pointer, the pointer corner bracket, PCBA plate and pad are formed and are arranged in order, copper core pointer passes counterdie and is connected with silicone gasket, and the pointer corner bracket is corresponding with copper core pointer and be fixed on the PCBA plate respectively and link to each other with the positive and negative level of battery.

Bonding between described shell, silica gel and the counterdie by glue.

The utility model is owing to adopt said structure, when air-breathing, because air switch shell, bonding between silica gel and the counterdie by glue, reach sealing effectiveness, silica gel upper surface space and lower surface space form pressure difference, so silicone gasket is deformed by the atmospheric pressure effect, thereby driving the copper post and the copper sheet indicating hand component that are attached thereto moves toward inspiratory direction, behind the motion certain distance, the copper sheet pointer contacts with copper sheet foot rest on the PBCA plate, and the PCBA plate is connected with battery by electric wire, this moment, circuit was connected. and when aspiratory action stopped, silicone gasket drove copper core copper sheet and keeps in the center, and this moment, copper sheet pointer and copper sheet foot rest broke away from, disconnect with circuit, avoided long-time connection heating wire.Compared with prior art have: access times are increased to 30-50 ten thousand, and the sensitivity of air switch improves more than 50% synchronously, the advantage that has improved the easness of integral installation simple in structure.
