[0031] like Figure 1-7As shown, this application provides a single cigarette simulated smoking detection device, including a base 1, which is horizontally arranged. A drive mechanism and a suction mechanism are mounted on the base 1. The drive mechanism is connected to the suction mechanism. The suction mechanism includes a suction cylinder 2 and a placement cylinder 3. A fixing ring 15 is provided between the suction cylinder 2 and the base 1. The suction cylinder 2 is horizontally arranged and fixedly mounted on the base 1 by the fixing ring 15. The placement cylinder 3 is threaded onto one end of the suction cylinder 2 and is coaxially arranged with the suction cylinder 2. A piston 13 is slidably installed axially inside the suction cylinder 2. A connecting rod 14 is fixedly installed on the side of the piston 13 facing away from the placement cylinder 3. Inside the suction cylinder 2, between the piston 13 and the placement cylinder 3, there is a first one-way valve 8. Inside the suction cylinder 2, between the piston 13 and the first one-way valve 8, there is an exhaust cylinder 7. One end of the exhaust cylinder 7 is connected to the suction cylinder 2. Inside the exhaust cylinder 7, there is a second one-way valve 9. In this embodiment, the first one-way valve 8 only allows gas to flow from the placement cylinder 3 into the suction cylinder 2, and the gas cannot flow back. The second one-way valve 9 only allows gas to flow from the suction cylinder 2 into the exhaust cylinder 7, and the gas cannot flow back. The drive mechanism includes a motor 16 and a rotating shaft 17. A first support plate 20 and a second support plate 21 are fixedly installed on the base 1. The motor 16 is fixedly installed on the first support plate 20 by bolts. The rotating shaft 17 is rotatably mounted on the first support plate 20. The rotating shaft 17 is horizontally positioned and one end of the rotating shaft 17 is fixedly connected to the output end of the motor 16. The other end of the rotating shaft 17 is vertically fixedly mounted with a rotating rod 18. The axis of the rotating shaft 17 is perpendicular to the axis of the suction cylinder 2. A rocker arm 19 is installed on the rotating rod 18. An adjustment mechanism is provided between the rocker arm 19 and the connecting rod 14. The end of the connecting rod 14 away from the piston 13 is fixedly connected to the adjustment mechanism. One end of the rocker arm 19 is hinged to the end of the rotating rod 18 away from the rotating shaft 17, and the other end is hinged to the adjustment mechanism. The hinge axis of the rocker arm 19 and the rotating rod 18, and the hinge axis of the rocker arm 19 and the adjustment mechanism are both parallel to the axis of the rotating shaft 17. The adjustment mechanism is used to adjust the suction capacity of the piston 13 on the cigarette.
[0032] The adjusting mechanism includes a fixed block 22, a sliding seat 24, and a sliding block 26. The fixed block 22 is fixedly installed on the second support plate 21. The fixed block 22 has a first dovetail groove 23 extending through the connecting rod 14. The shape of the sliding seat 24 matches the first dovetail groove 23 and is slidably installed in the first dovetail groove 23. The sliding seat 24 has a second dovetail groove 25 extending through the connecting rod 14. Neither end of the second dovetail groove 25 extends through the side wall of the sliding seat 24. The shape of the sliding block 26 matches the second dovetail groove 25 and is slidably installed in the second dovetail groove 25. A support rod 32 protruding from the second dovetail groove 25 is installed on the sliding block 26. The end of the swing rod 19 away from the rotating rod 18 is rotatably fitted onto the support rod 32. The end of the connecting rod 14 away from the piston 13 is fixedly connected to the end face of the sliding seat 24. In this embodiment, the motor 16 rotates, driving the rotating shaft 17 and the rotating rod 18 to rotate. The rotating rod 18 drives the swing rod 19 to swing. Under the guiding and limiting action of the first dovetail groove 23, the swing rod 19 causes the sliding block 26 to reciprocate along the axial direction of the suction cylinder 2 in the second dovetail groove 25. When the sliding block 26 abuts against the side wall of the first dovetail groove 23, the sliding block 26 drives the sliding seat 24 to reciprocate in the first dovetail groove 23, thereby causing the connecting rod 14 and the piston 13 to reciprocate in the suction cylinder 2. With the help of two one-way valves, one-way air intake of the placement cylinder 3 can be achieved, thereby achieving the purpose of simulating suction.
[0033] A limiting block 27 is slidably installed within the second dovetail groove 25. An adjusting member 28 is provided between the limiting block 27 and the side wall of the second dovetail groove 25. The sliding seat 24 is provided with a threaded hole for the adjusting member 28 to pass through. One end of the adjusting member 28 passes through the threaded hole and is rotatably connected to the limiting block 27. In this embodiment, the adjusting member 28 is a bolt. By turning the adjusting member 28, the limiting block 27 can slide within the second dovetail groove 25, thereby changing the position of the limiting block 27. Consequently, the contact position between the sliding block 26 and the limiting block 27 changes during the reciprocating motion, thus changing the reciprocating distance of the sliding seat 24. The structure is simple and the adjustment is convenient.
[0034] An anti-loosening nut 29 is provided between the sliding seat 24 and the adjusting member 28 to increase the connection stability between the adjusting member 28 and the sliding seat 24.
[0035] The coefficient of friction between the sliding block 26 and the sliding seat 24 is less than the coefficient of friction between the sliding seat 24 and the fixed block 22. With this structural design, when the rocker arm 19 drives the sliding block 26 to reciprocate in the second dovetail groove 25, if the sliding block 26 does not contact the side wall of the second dovetail groove 25 or the limiting block 27, the sliding seat 24 will not slide in the fixed block 22. Only when the sliding block 26 contacts the side wall of the second dovetail groove 25 or the limiting block 27 will the reciprocating motion of the sliding block 26 drive the sliding seat 24 to move.
[0036] The first one-way valve 8 and the second one-way valve 9 have the same structure. The first one-way valve 8 includes a retaining ring 10, a cross mounting bracket 11 and a rubber disc 12. The retaining ring 10 is fixedly installed on the inner wall of the suction cylinder 2. The outer diameter of the retaining ring 10 is the same as the inner diameter of the suction cylinder 2. The cross mounting bracket 11 is fixedly installed inside the retaining ring 10. The rubber disc 12 is fixedly installed on the cross mounting bracket 11 and the rubber disc 12 is attached to the side of the retaining ring 10 facing the piston 13. The diameter of the rubber disc 12 is larger than the inner diameter of the retaining ring 10 and smaller than the outer diameter of the retaining ring 10. In this embodiment, the second one-way valve 9 also includes a retaining ring 10, a cross mounting bracket 11, and a rubber disc 12. The retaining ring 10 is fixedly installed on the inner wall of the exhaust pipe 7, and the rubber disc 12 is attached to the side of the retaining ring 10 facing away from the suction cylinder 2. With this structural design, when the piston 13 moves away from the first one-way valve 8, a negative pressure is formed inside the suction system. The air in the placement cylinder 3 forces the edge of the rubber disc 12 of the first one-way valve 8 to bend, and the air in the placement cylinder 3 flows into the suction cylinder 2 through the edge of the rubber disc 12 of the first one-way valve 8. At this time, the rubber disc 12 of the second one-way valve 9 is limited by the cross mounting bracket 11 and the retaining ring 10, and the external... Air cannot flow into the suction cylinder 2 through the second one-way valve 9; when the piston 13 moves horizontally back, that is, when the piston 13 moves towards the first one-way valve 8, the air in the suction cylinder 2 forces the edge of the rubber disc 12 of the second one-way valve 9 to bend, and the air in the suction cylinder 2 flows out of the exhaust pipe 7 and is discharged to the outside through the edge of the rubber disc 12 of the second one-way valve 9. At this time, the rubber disc 12 of the first one-way valve 8 is limited by the cross mounting bracket 11 and the retaining ring 10, and the air in the suction cylinder 2 cannot flow into the placement cylinder 3 through the first one-way valve 8, realizing one-way air intake of the placement cylinder 3, thereby achieving the purpose of simulating suction. The structure is simple and the use is reliable.
[0037] A mounting base is provided below the base 1. One end of the base 1 is hinged to the mounting base, and a telescopic member 31 is provided between the other end of the base 1 and the mounting base. One end of the telescopic member 31 is hinged to the mounting base, and the telescopic end of the telescopic member 31 is hinged to the base 1. In this embodiment, the telescopic member 31 is a cylinder. By extending and retracting the cylinder, the smoking angle of the cigarette can be adjusted, making the simulated smoking behavior more consistent with the actual smoking behavior. This allows for obtaining an optimized smoking angle range through simulation, thereby improving the user's smoking experience. The structure is simple and the operation is convenient.
[0038] The placement cylinder 3 is equipped with a partition 4, which divides the internal space of the placement cylinder 3 into a first chamber and a second chamber. The first chamber forms a mouthpiece, into which the cigarette to be tested is inserted. The second chamber is equipped with a filter element 5. Several through holes 6 are opened on the partition 4. Tar can be filtered through the filter element 5. Regularly replacing the filter element 5 can effectively prevent the one-way valve and the suction cylinder 2 from being contaminated, eliminating the need for frequent cleaning.
[0039] Working principle:
[0040] During use, the cigarette to be tested is inserted into the mouthpiece and lit. Then, the suction volume is adjusted according to the needs. Adjustment is achieved by turning the adjusting component 28. Since the adjusting component 28 is screwed onto the sliding seat 24, when the adjusting component 28 rotates, it drives the limiting block 27 to move axially along the suction cylinder 2. This causes the contact position between the sliding block 26 and the limiting block 27 to change during the reciprocating motion. As a result, the reciprocating motion distance of the sliding seat 24 is changed, which in turn changes the axial displacement distance of the connecting rod 14 and the piston 13 after one revolution of the rotating shaft 17 and the rotating rod 18. This completes the adjustment of the single suction volume. During the reciprocating movement of the piston 13, the two one-way valves can cooperate to achieve one-way air intake of the placement cylinder 3, thereby achieving the purpose of simulating inhalation and simulating smoking.
