[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] In the prior art, the burning cone of the cigarette 5 is extinguished by applying a flame retardant gas to the outside of the burning cone of the cigarette 5. However, the burning cone of the cigarette 5 in the above manner will continue to burn for a while before it can be extinguished. The applicant has discovered that the reason why the burning cone of the cigarette 5 cannot be extinguished instantly by applying a flame retardant gas to the outside of the cigarette 5 is that there is air inside the cigarette 5, so the burning cone continues to burn inside the cigarette 5 for a while before it can be extinguished.

[0027] In order to solve the above technical problems, the embodiment of the utility model provides a cigarette extinguishing device, which is arranged on the air inlet of the smoking machine. The cigarette extinguishing device includes a base 1, and the base 1 is provided with a first direction ( Figure 1 The through hole 2 (shown in the X direction) runs through itself, the through hole 2 includes a smoke receiving hole 3 and a suction hole 4 arranged in sequence along the first direction, the suction hole 4 is connected to the suction port, and the smoke receiving hole 3 is used to insert a cigarette 5; the base 1 is also provided with a vent hole 6, the vent hole 6 extends along the radial direction of the through hole 2, the first end of the vent hole 6 is connected to the suction hole 4, and the second end of the vent hole 6 is connected to the gas source, and the gas source is used to output the flame retardant gas.

[0028] By adopting the above technical solution, a vent hole 6 is provided on the base 1, and the suction hole 4 is connected to the gas source of the flame retardant gas through the vent hole 6. The flame retardant gas is introduced into the suction hole 4 through the vent hole 6 (the flow direction of the flame retardant gas is as follows): Figure 1 As shown by the arrow Z in the figure, the flame retardant gas can flow from the inside of the cigarette 5 into the combustion cone, so that the combustion cone is instantly extinguished in the atmosphere of the flame retardant gas, making it easy to observe the morphological structure of the tobacco at the moment the combustion cone is extinguished.

[0029] Furthermore, it also includes a control system and a solenoid valve. The vent hole 6 and the gas source are connected through a pipeline. The solenoid valve is arranged on the pipeline. The control system is electrically connected to the smoking machine and the solenoid valve. The solenoid valve is a normally closed solenoid valve. When the smoking machine stops sucking the cigarette 5, the control system can control the solenoid valve to open, so that the flame retardant gas flows into the vent hole 6 through the pipeline and enters the inside of the cigarette 5 through the suction hole 4. Specifically, the smoking machine is provided with a control valve connected to the air inlet. When the smoking machine stops sucking the cigarette 5, the control valve is closed, which can prevent the flame retardant gas from entering the inside of the smoking machine and affecting the detection result of the smoking machine on the smoke. At the same time, the flame retardant gas can be fully flowed into the inside of the cigarette 5 to avoid the waste of the flame retardant gas.

[0030] Furthermore, the base 1 is plugged into the air inlet, and one end of the base 1 close to the suction hole 4 is inserted into the air inlet, and a sealing ring 7 is provided between the base 1 and the air inlet. The sealing ring 7 can prevent smoke from leaking from between the base 1 and the air inlet, thereby improving the accuracy of the smoke detection result of the smoking machine. The sealing ring 7 can also prevent the flame retardant gas from leaking from between the base 1 and the air inlet, thereby reducing the waste of the flame retardant gas.

[0031] Furthermore, a temperature sensor 8 is included. A temperature measuring hole 9 is provided on the side wall of the base 1. The temperature measuring hole 9 is connected to the cigarette receiving hole 3. The detection end of the temperature sensor 8 passes through the temperature measuring hole 9 and is inserted into the cigarette receiving hole 3. When the smoking machine draws the cigarette 5, the temperature sensor 8 can detect the temperature of the smoke released from the cigarette 5. When the cigarette 5 is extinguished, the temperature sensor 8 can detect the temperature change in the cigarette receiving hole 3 during the extinguishing process of the cigarette 5, so that the cigarette machine can judge the influence of the temperature change in the cigarette receiving hole 3 on the tobacco structure inside the cigarette 5.

[0032] Furthermore, the diameter of the smoke receiving hole 3 is larger than the diameter of the suction hole 4, a step 12 is formed between the smoke receiving hole 3 and the suction hole 4, a flexible gasket 11 is provided in the smoke receiving hole 3, a first surface 14 of the flexible gasket 11 is in contact with the step 12, and a second surface 15 of the flexible gasket 11 is in contact with the wire 10 of the temperature sensor 8. A fastening ring is sleeved in the smoke receiving hole 3, the inner diameter of the fastening ring is larger than the diameter of the cigarette 5, and the suction end 13 of the cigarette 5 is inserted in the fastening ring. The outer periphery of the fastening ring is provided with an external thread, and the inner wall of the smoke receiving hole 3 is provided with an internal thread. The fastening ring is threadedly connected to the smoke receiving hole 3. When the fastening ring is tightened, it can press the wire 10 of the temperature sensor 8 toward the flexible gasket 11 to fix the position of the temperature sensor 8, so as to prevent the temperature sensor 8 from shaking and affecting the airflow stability in the smoke receiving hole 3.

[0033] Furthermore, the inner diameter of the flexible gasket 11 is smaller than the diameter of the cigarette 5, and the end surface of the suction end 13 of the cigarette 5 contacts the second surface 15. The second surface 15 can limit the depth of the cigarette 5 inserted into the cigarette receiving hole 3. Figure 1 The projection of the detection end of the temperature sensor 8 falls on the end surface of the suction end 13, and the detection end of the temperature sensor 8 contacts the suction end 13 of the cigarette 5. The second direction is opposite to the first direction, which is convenient for timely detection of the temperature of the smoke released from the cigarette 5.

[0034] Furthermore, it also includes a cap 16 and a silicone gasket 17. The cap 16 is sleeved on the end of the base 1 away from the smoking machine. The cap 16 is threadedly connected to the base 1. The silicone gasket 17 is arranged between the end surface of the base 1 and the end surface of the cap 16. A cigarette insertion hole 18 is arranged on the end surface of the cap 16. The inner diameter of the silicone gasket 17 is equal to the diameter of the cigarette 5, and the diameter of the cigarette insertion hole 18 is larger than the diameter of the cigarette 5. When the cap 16 is tightened, the cap 16 and the end surface of the base 1 squeeze the silicone gasket 17, causing the silicone gasket 17 to deform, so as to squeeze the cigarette 5 inserted into the silicone gasket 17, thereby fixing the cigarette 5 in the cigarette receiving hole 3 to prevent the cigarette 5 from falling out of the cigarette receiving hole 3.

[0035] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
