Technical Field

[0001] The invention belongs to the technical field of heated cigarette smoking articles, and in particular relates to a sealed smoking device with an air extraction function and a use method thereof. Background Art

[0002] Heated cigarette products are accepted and liked by more and more consumers due to their low hazard and the technological elements contained in such products. The principle of heated cigarettes is to use baking to make tobacco substances volatilize nicotine and other specific chemicals in a low temperature environment, avoiding the production of harmful substances by high temperature combustion. However, oxygen is inevitably present in smoking utensils, causing some tobacco substances to be oxidized and burned, volatilizing certain harmful substances such as tar. Therefore, if the heating chamber of the cigarette can be made into a sealed oxygen-free environment, aerobic combustion of tobacco substances can be avoided, and the harmful substances produced by tobacco substances will be greatly reduced.

[0031] The content of the present invention is further explained below through specific implementation examples.

[0032] Example 1

[0033] like Figure 1-2 , a sealed smoke generating device with an exhaust function, the specific structure is as follows:

[0034] The bottom of the heating chamber 2 is connected to an air pump 6 through a connecting port 4 and a connecting channel 5. An exhaust port 8 and a switch 7 are provided on the other side of the air pump 6.

[0035] When the switch 7 is pressed, the vacuum pump 6 starts working, automatically exhausting the air inside the heating chamber 2 and letting it out through the exhaust port 8. When the heating chamber sensing device 2a at the bottom of the heating chamber 2 senses that there is almost no air inside the heating chamber 2, the exhaust port 8 is closed by the control device.

[0036] At the same time, after a delay of two seconds, the heating chamber sensing device 2 a starts the heating chamber 2 through the control device circuit board 12 to start heating and bake the cigarette 1 .

[0037] The heating cavity opening 3 at the upper end of the heating cavity 2 is provided with a sealing ring 3a, on which a cigarette sensing device 3b is provided. The bottom side of the cigarette 1 is provided with a sensing sheet 1a, and when the cigarette 1 approaches the sealing ring 3a, the cigarette sensing device 3b senses the cigarette 1, outputs a signal, controls the sealing ring 3a to open automatically, and the cigarette 1 can be placed in the heating cavity 2.

[0038] There is also a bottom sensing device at the bottom of the heating chamber 2. When the side sensing sheet at the bottom of the cigarette 1 approaches or touches it, the bottom sensing device outputs a signal to control the sealing ring 3a to automatically close until it fits with the periphery of the cigarette, thereby achieving the purpose of sealing the gap between the heating chamber 2 and the cigarette 1.

[0039] The heating chamber 2 and the vacuum pump 6 are connected to a battery 11 via a power line 19 and a power line 210 respectively, and the battery 11 provides electrical energy to the heating chamber 2 and the vacuum pump 6.

[0040] The bottom contact sensing device at the bottom of the heating chamber 2 can be the same as the heating chamber sensing device 2a, that is, it has a bottom contact function and an air sensing function.

[0041] The connecting port 4 and the connecting channel 5 can be in close contact with each other by means of a bayonet or a screw, so as to facilitate the replacement of the vacuum pump at a later time.

[0042] The method of using the sealed smoke generating device is as follows:

[0043] When a cigarette 1 with a sensor sheet at the bottom is put into the smoking device, the heating cavity 3 of the smoking device has a cigarette sensing device 3b. When the sensor sheet of the cigarette is sensed, the rubber ring of the heating cavity of the smoking device automatically opens, and the cigarette can be put in.

[0044] When the cigarette 1 is placed at the bottom of the heating chamber 2, the heating chamber sensing device 2a at the bottom of the heating chamber 2 senses the signal from the cigarette sensing sheet and feeds it back to the rubber ring through the circuit board or other media. The rubber ring automatically closes and fits closely to the outer periphery of the cigarette 1. Figure 3 .

[0045] Press the switch 7, the air pump 6 starts to work, and the air in the heating chamber 2 is discharged through the exhaust port 8 through the connecting channel 5, the connecting port 4 and other channels. When the heating chamber sensing device 2a at the bottom of the heating chamber 2 senses that there is no air in the heating chamber 2, it transmits a signal to the circuit board or other medium to close the exhaust port 8, forming an airless environment in the heating chamber 2. At the same time, the sensing device 2a starts the heating chamber 2 through the circuit board or other medium after a delay of two seconds to start heating, and bake the cigarette 1.
