Detailed Description

The present invention will be further described with reference to the following embodiments.

Example 1

Referring to fig. 1-2, a sealed smoking assembly with an air reservoir includes a sealed smoking device and a cigarette 1.

The cigarette 1 comprises a tobacco section containing tobacco materials and a non-tobacco section without the tobacco materials, and the circumferential outer wall of the non-tobacco section is provided with cigarette air holes 2 formed by laser drilling.

The sealed smoke generating device comprises the following components:

a clamper 3, a heating cavity 4, an air storage chamber 5, a compression cavity 7, a spring 8, a key 9, a suction pump 11, a switch 10, a battery 12,

the clamping part at the upper part of the clamp holder 3 can be flexibly opened and closed and is tightly contacted with the cigarette 1 when closed. The lower part of the clamp holder 3 is integrated with the air storage chamber 5. The contact part of the holder 3 and the cigarette 1 is a tubular structure, and the section is provided with a holder air outlet 3 a. The air outlet 3a of the clamp holder is communicated with the cigarette air holes 2.

Heating material is arranged on the inner wall of the heating cavity 4, and cigarettes can be heated. The bottom of the heating chamber 4 communicates with the inlet 11a of the getter pump 11. The heating cavity 4 is made of soft material and has a certain deformation function.

The air reservoir 5 primarily stores air from outside the smoke generating device through the smoking set air inlet 6 and air from inside the heating chamber 4, which can flow out of the holder air outlet 3 a.

In addition, the air reservoir 5 may be compressed. The other function is that when the spring is extruded upwards, the cigarette in the heating cavity can be pushed out of the heating cavity. The smoking set air inlet 6 is located on the outer wall of the air storage chamber 5, and the size and the number of the air inlets are set according to the smoke quantity requirement. For example two air inlets of 1mm diameter.

The function of the suction pump 10 is mainly to suck air in the heating chamber 4 through the gas inlet 11a and discharge the air into the air reservoir 5 through the gas outlet 11 b. At the same time, the gas inlet 11a or the gas outlet 11b can be closed, so as to ensure that the air in the air storage chamber 5 does not enter the heating chamber 4. The diameter of the air inlet pipe and the air outlet pipe of the air suction pump 11 is 5-8 mm.

The compression cavity 7 is tightly connected with the air storage chamber 5, the diameters of the compression cavity 7 and the air storage chamber are the same, and a spring 8 which is vertically arranged is arranged in the compression cavity 7.

The bottom of the compression cavity 7 forms a closed space, namely a key 9, and the upper part of the key 9 is tightly connected with the spring 8. At the same time, the keys 9 can be moved upwards, since the compression chamber 7 can be compressed. When the push button 9 is pressed externally, the whole inner wall of the compression cavity 7 moves upwards, and the spring 8 is pushed upwards. When the spring 8 is not pressed, the spring is in a natural state; when the bottom of the spring 8 is extruded by the button 9, the compression cavity 7 can be moved upwards and then extruded with the air storage chamber 5 and the heating cavity 4 moving upwards, and the cigarette 1 in the heating cavity 4 can be ejected out by the moving stroke.

Pressing the switch 2 controls the start and stop of the getter pump 11. The battery 12 supplies power to the heating chamber 4.

The use method of the sealed smoking assembly comprises the following steps:

A. the cigarette 1 is placed in the heating chamber 4, and the clamping part of the clamp holder 3 is closed to clamp the cigarette;

B. after the switch 10 is started, the switch 10 controls the getter pump 11 to start working;

C. after the air suction pump 11 works, discharging the gas in the heating cavity 4 into the gas storage chamber 5, delaying for 3-10s, automatically closing the air suction pump 11 and the gas inlet 11a, and starting the heating cavity 4 to heat the cigarettes 1;

D. when the user sucks, the suction force drives the air flow in the air storage chamber 5 to pass through the air outlet 3a of the holder and the communicating channel of the cigarette air holes 2 to enter the non-tobacco section of the cigarette 1, and finally the smoke generated by the tobacco section is sucked after being mixed.

E. After the user finishes pumping, the key 9 is pressed down, the key 9 drives the vertical spring 8 to move upwards, the cigarette 1 in the heating chamber 4 is ejected out, and the purpose of automatically discarding the cigarette is achieved.
