[0026] The first gas pipe 30 is respectively arranged on the left and right sides of the diverter 20, wherein the diverter 20 is fixed to the upper part of the base 10, and the central axis of the diverter 20 is on the same vertical line as the central axis of the base 10. The sleeve 40 is respectively connected to the end of the first gas pipe 30 away from the diverter 20, and the sleeve 40 is respectively connected to one end of the fixing frame 50, while the other end of the fixing frame 50 is fixedly connected to the base 10. The material receiving trough 90 is respectively arranged on both sides of the base 10, and the material receiving trough 90 is respectively located below the end of the sleeve 40 away from the first gas pipe 30, and the spring 101 is embedded in the sleeve 4 0, and the spring piece 101 arches toward the axial center line direction of the sleeve 40, the piston 110 is installed in the sleeve 40 at one end near the first gas pipe 30, and the piston 110 is fixedly connected to the limit member 120, the limit member 120 is slidably connected to the slide groove 130, and the slide groove 130 is opened on the inner wall of the sleeve 40, the connecting pipe 150 is located at the end of the piston 110 near the first gas pipe 30, and the connecting pipe 150 passes through the end of the sleeve 40 near the first gas pipe 30 and is inserted into the first gas pipe 30, and the one-way valve 140 is located on one side of the piston 110 near the inlet end of the sleeve 40.

[0027] The interior of the diverter 20 is a hollow structure, and the interior of the diverter 20 is connected to the first air pipe 30, and the interior of the diverter 20 is connected to the interface 60 located at the front and rear ends of the diverter 20. The interface 60 is combined with the second air pipe 70 to facilitate the series connection of multiple devices, thereby improving practicality.

[0028] The sleeve 40 and the fixing frame 50 are symmetrically arranged in two groups about the central axis of the diverter 20, and each group of sleeves 40 and fixing frames 50 are arranged with four sleeves 40 and fixing frames 50 at equal intervals. At the same time, the fixing frame 50 is located at the top of the base 10 near the edge. The fixing frame 50 is convenient for providing support for the sleeve 40, and the rotating connection method facilitates the adjustment of the angle of the sleeve 40 according to needs.

[0029] The sleeve 40 is rotatably connected to the fixing frame 50, and the inlet end of the sleeve 40 is respectively arranged at the end of the sleeve 40 away from the first air pipe 30. At the same time, the inner wall of the end of the sleeve 40 away from the first air pipe is provided with a chamfer, which facilitates the wrapping of the filter part of the cigarette through the sleeve 40, and the chamfer improves the convenience of installing the cigarette.

[0030] Four spring pieces 101 are arranged at equal angles in the middle section of the inner wall of the sleeve 40, and the minimum distance between two symmetrical spring pieces 101 is smaller than the inner wall diameter of the sleeve 40. The spring pieces 101 facilitate clamping the filter tip of the cigarette, thereby improving the fixing effect of the cigarette.

[0031] There are two material receiving troughs 90 symmetrically arranged about the central axis of the base 10, and the top ends of the material receiving troughs 90 are both inner trough structures.

[0032] The piston 110, the one-way valve 140, the connecting pipe 150 and the first air supply pipe 30 are interconnected, and the connecting pipe 150 and the one-way valve 140 follow the piston 110 to slide along the slide groove 130 through the limit member 120. The one-way valve 140 is used to facilitate the control of the direction of the airflow, and then the airflow pushes the piston 110 to slide, so that the cigarette butt can be pushed out by the sliding of the piston 110, thereby improving practicality.

[0033] The outer diameter of the piston 110 is equal to the inner diameter of the sleeve 40, and the axis of the sleeve 40 and the axis of the piston 110 are on the same horizontal straight line. The piston 110 improves the airtightness of the device during vacuuming and improves the use effect.

[0035] The method of using the present invention is as follows: first, seal the idle interface 60, then insert the filter tip of the cigarette to be tested into the sleeve 40 through the inlet end of the sleeve 40 respectively. During the process of inserting the filter tip into the sleeve 40, the spring piece 101 will be squeezed toward the inner wall of the sleeve 40. The deformed spring piece 101 generates a rebound force to clamp the filter tip of the cigarette. At the same time, during the process of inserting the filter tip into the sleeve 40, the one-way valve 140 will be pushed to drive the limiter 120 to slide along the slide groove 130 toward the first air supply pipe 30. Then, light the cigarettes in turn, connect the external power supply, start the integrated air pump 80, and drive the external air flow to pass through the cigarette, piston 110, one-way valve 140 and connecting pipe 150 in turn. Then it enters the diverter 20 through the first air supply pipe 30, and is finally discharged through the integrated air suction and air supply pump 80, thereby forming an air circulation, thereby simulating the burning of the cigarette during the smoking process. During the detection process, the ash produced by the burning of the cigarette will fall into the receiving trough 90, and the ash will be collected centrally through the receiving trough 90. When the detection is completed, the external air flow is driven by the integrated air suction and air supply pump 80 to pass through the diverter 20, the first air supply pipe 30 and the connecting pipe 150 in turn into the piston 110. At this time, the one-way valve 140 will block the air flow from passing through the end of the piston 110 close to the cigarette, and then the air flow will drive the piston 110 as a whole to start moving toward the cigarette, and finally push the filter tip of the cigarette to be discharged outward.
