Abstract

The utility model relates to an electronic cigarette, which comprises a cigarette holder (1) and a suction nozzle (2), wherein the cigarette holder (1) comprises a press key (11), a printed circuit board (PCB) (12) and a PCB support frame (13). The electronic cigarette is characterized in that the outer vertical wall of the press key (11) is contracted from the outer side to the inner side, and a side wall (131) of a hole (14) arranged on the PCB support frame (13) for accommodating the press key (11) is contracted from the outer side to the inner side and is anastomotic with the outer vertical wall of the press key (11). Compared with the prior art, the electronic cigarette has the technical effects that the press key cannot be clamped by the PCB support frame in the use process, and the use of the press key is flexible.

Description

The electronics cigarette

Technical fieldThe utility model relates to the electronics cigarette, particularly relates to the structure of electronics cigarette.

Background technologyThe electronics cigarette has another name called virtual cigarette, atomizer for electric, and it has the outward appearance the same with cigarette, the taste approximate with cigarette, even will have more much than the taste of general cigarette, also as cigarette can the sucking-off cigarette, the sucking-off taste is next with sensation.Mainly be to be used for smoking cessation and alternative cigarette.The electronics cigarette is a kind of on-fuel cigarette class substituted type product, and it is similar with some characteristic of common cigarette, can refresh oneself, satisfy smoker's pleasant sensation and the use habit of forming for many years.But have in essence different, electronics cigarette not to burn, do not contain tar with common cigarette, the meeting that produces when not containing common cigarette burning causes respiratory system and disease of cardiovascular system surplus in the of 460 kind of chemical substance, thereby removed the carcinogen in the common cigarette.Can not produce the harm and the contaminated environment of " second-hand-cigarette " to other people.

Some electronic cigarettes uses electron gas flow sensor to start this heating element heater, and one air-breathingly will make battery circuit work.And manually induction need the user by next button, smoking then.Comparatively speaking, manual circuit is than aerodynamic stbilization, and the smoke amount is also good than pneumatic.But the button outer upright wall of manual electronic cigarette often blocks with the inwall of PCB support mutually, uses inconvenient.

The utility model contentThe utility model technical problem to be solved is to provide that a kind of button outer upright wall can not block with the inwall of PCB support mutually, button uses electronics cigarette flexibly.

The utility model is realized through taking following technical scheme:

Design, a kind of electronics cigarette of making; Comprise tobacco rod and suction nozzle, said tobacco rod includes button, PCB and PCB support, the outer upright wall of said button from outside narrow toward in; Be used on the said PCB support to hold said button the hole sidewall from outside narrow toward in, coincide with the outer upright wall of said button.

Be extended with flange on the sidewall in the hole of said electronics cigarette.

Compared with prior art, the utlity model has button and in use can not block with the PCB support, button uses technique effect flexibly.

Fig. 2 is the stereogram of said electronics cigarette;

Fig. 3 is the schematic perspective view of the button of said electronics cigarette;

Fig. 4 is the vertical section sketch map of Fig. 3;

Fig. 7 is the A-A cutaway view of Fig. 6.

The specific embodimentBelow in conjunction with preferred embodiment the utility model is done further detailed description.

To shown in Figure 7, a kind of electronics cigarette comprises tobacco rod 1 and suction nozzle 2 like Fig. 1, and said tobacco rod 1 includes button 11, PCB 12 and PCB support 13.The outer upright wall 111 of said button 11 from outside narrow toward in, be used on the said PCB support 13 to hold said button 11 hole 14 sidewall 131 from outside narrow toward in, coincide with the outer upright wall 111 of said button 11.Like this, avoided button 11 in use to block mutually with hole 14 sidewalls of PCB support 13.

Like Fig. 5, shown in Figure 6, be extended with flange 15 on the sidewall of said PCB support 13 endoporus 14, be used for cooperating with the bottom surface 112 of button 11.When the user applied power on the button and is not perpendicular to keytop, flange 15 can play the effect of baffle plate, avoids button 11 to trigger PCB.

When using the electronics cigarette, push button 11 earlier.When air-breathing, pneumatic sensor perception human mouth is air-breathing in the electronics cigarette, thereby trigger gas spreads the sense switch, and the air-flow sensitive switch is opened, and product begins to get into duty.CPU is through calculating and measure, and reaches atomizing in various degree according to the extent control atomizer of oral suction.Atomizer is made up of high-frequency oscillating circuits and heating wire; In atomizer; The high pure electronic tobacco juice gets into spray chamber after the pressurization of ultra micro atomizer pump, super critical mist changes into the droplet about 0.5-1.5um in the vibrations field of high-frequency ultrasonic, cooperates the air-flow that sucks to be dispersed into aerocolloidal form again; And then the steam fog of formation simulated flue gas, outer appearnce is like cigarette.Critical atomization condition is that the mode with heating makes surface tension of liquid be reduced to the degree of the easiest atomizing, has also simulated the temperature (50-60 degree centigrade) of common flue gas in the time of simulation smoke.The green indicating lamp of electronics cigarette front end is lighted simultaneously, and simulation cigarette end flame shows that the electronics cigarette is in duty.When stopping suction, the air-flow in the sensor disappears, and the air-flow sensitive switch cuts out, and CPU quits work, and atomizer quits work, and the green of electronics cigarette front end is designated as to be extinguished.

Above content is the further explain that combines concrete optimal technical scheme that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
