TECHNICAL FIELD

The present invention belongs to the field of electronic cigarette, specifically relates to a device with a separated gas inlet for cigarette set.

BACKGROUND

In the existing cigarette set for electronic cigarette, the traditional tobacco and controller switch share the same gas inlet channel, and the cigarette smoke passes through the hole on the controller switch. Since the smoke contains tarry matters, the tarry matters may attach on the hole, and with the increase of smoking cigarette, the tarry matters may accumulate to completely block the hole, causing a failure of the controller switch.

SUMMARY

In order to solve the above-mentioned problem, based on the existing structure with shared gas channel, the present invention provides a device with a separated gas inlet for cigarette set. Namely, air inlet channel for initiating a controller switch is separated from a smoke gas channel of a cigarette, avoiding the failure of the controller switch caused by tarry matters of traditional cigarette attaching on an initiating hole of the controller switch, and prolonging the service life of an electronic cigarette in cigarette set. A device with a separated gas inlet for cigarette set of the present invention includes:

a controller switch2, wherein the controller switch is a cylindrical airflow sensor having two ends, and air can flow between the two ends;

a controller switch seat3, wherein the controller switch seat is a cylinder-like structure with two ends, air can flow through each end, an inner cylinder is a controller switch hole301tightly attached to an outer wall of the controller switch2, a wall perpendicular to an end of the controller switch seat3is provided with a U-shaped controller switch gas inlet channel302connecting an interior of the cylinder to an exterior of the cylinder, and the wall of the end is provided with an outer side wall groove305, two grooves are provided along an axial direction of an outer side wall of the cylinder, namely, a first clamping guide groove303and a cigarette gas inlet channel304, respectively;

a transparent light guide seat4, wherein the transparent light guide seat is a cylinder-like structure closed in the middle, a second clamping guide groove401is provided along an axial direction of an inner side of an outer wall of the cylinder, a wall perpendicular to an end of the transparent light guide seat4is provided with a U-shaped controller switch gas inlet groove403connecting an interior of the cylinder to an exterior of the cylinder, and the end is provided with a controller switch matching protruding wall404projecting outwards and tightly attached to the outer side wall groove305, a closed central part in the middle of the cylinder is a controller switch hole plug402, a first cigarette gas inlet hole405connected to the cigarette gas inlet channel304is provided between the controller switch hole plug402and the cylinder wall;

a filter holding seat5, wherein the filter holding seat5is a cylinder-like structure with a closed end, a plurality of small holes provided on the closed end are second cigarette gas inlet holes502, a clamping guide column501protruding along an axial direction of the closed end is in an interference fit respectively with the first clamping guide groove303and the second clamping guide groove401, the filter holding seat5is sealed and in a clearance fit with another end of the transparent light guide seat4, and the controller switch seat3is in a interference fit with the transparent light guide seat4;

the second cigarette gas inlet holes502are respectively connected to the first cigarette gas inlet hole405and the cigarette gas inlet channel304on the controller switch seat3through a gap between the filter holding seat5and the transparent light guide seat4;

an insulation fixing sleeve6, wherein the insulation fixing sleeve is in a cylindrical-like shape, and sleeves outside the filter holding seat5in an interference fit;

a charging base7, wherein the charging base is in a cylindrical-like shape, an upper portion of the charging base is sleeved outside the insulation fixing sleeve6in an interference fit, a lower portion of the charging base is sleeved inside a mouthpiece tube1, a middle portion of the charging base is provided with a plurality of gas guide holes71connected to the controller switch gas inlet groove403and the controller switch gas inlet channel302;

the air enters the controller switch gas inlet groove403and the controller switch gas inlet channel302from the gas guide holes71, and then enters the controller switch2, to initiate the electronic cigarette;

while the smoke gas enters the gap between the filter holding seat5and the transparent light guide seat4from the second cigarette gas inlet holes502to enter the first cigarette gas inlet hole405, and then enters the cigarette gas inlet channel304, and thus the mouthpiece tube1.

Preferably, the lower portion of the charging base7is sleeved inside the mouthpiece tube1in an interference fit.

Preferably, the cigarette gas inlet channel304is connected to the mouthpiece tube1.

The working principle of the device with the separated gas inlet for cigarette set of the present invention is as follows.

The controller switch2is installed in the controller switch seat3, the controller switch seat3is in an interference fit with the transparent light guide seat4, and the controller switch gas inlet groove403is connected to the controller switch gas inlet channel302. The transparent light guide seat4is in a clearance fit with the filter holding seat5to make the second cigarette gas inlet holes502connected to the gap between the filter holding seat5and the transparent light guide seat4, the first cigarette gas inlet hole405, and the cigarette gas inlet channel304. The clamping guide column501is in an interference fit respectively with the first clamping guide groove303and the second clamping guide groove401. The insulation fixing sleeve6is sleeved outside the filter holding seat5in an interference fit. The charging base7is sleeved outside the insulation fixing sleeve6in an interference fit, and an outer side of another end of the charging base7is in an interference fit with an inner side of the mouthpiece tube1to make the gas guide holes71connected to the controller switch gas inlet groove403and the controller switch gas inlet channel302.

The air enters the controller switch gas inlet groove403and the controller switch gas inlet channel302from the gas guide holes71, and then enters the controller switch2, to initiate the electronic cigarette.

While, the smoke gas enters the gap between the filter holding seat5and the transparent light guide seat4from the second cigarette gas inlet holes502to enter the first cigarette gas inlet hole405, then enters the cigarette gas inlet channel304, and thus the mouthpiece tube1for user to smoke.

The advantages of the present invention are as follows.

Based on the existing structure sharing the same gas channel, the present invention provides a device with a separated gas inlet for cigarette set. Namely, air inlet channel for air initiating a controller switch is separated from smoke gas channel for cigarette, avoiding the failure of the controller switch caused by tarry matters of traditional cigarette attaching on an initiating hole of the controller switch, and prolonging the service life of cigarette set.
