[0034] At present, when conducting comprehensive tests on cigarettes, the resistance to draw detection unit often generates abnormal alarms when the cigarettes enter the resistance to draw detection unit from the round length detection unit, and the resistance to draw data displayed on site is abnormal, which affects the detection efficiency.

[0035] In order to solve the above technical problems, the inventors have explored and discovered that the main reason why the current resistance to draw detection unit often generates abnormal detection data is: since there is a certain distance between the round length detection unit and the resistance to draw detection unit, and the cigarette is prone to skew when entering the resistance to draw detection unit from the round length detection unit, the cigarette deviates from the preset running path and cannot smoothly enter the resistance to draw detection unit, which in turn causes the resistance to draw detection unit to generate an abnormal alarm, and the on-site display of resistance to draw data is abnormal, affecting the detection efficiency.

[0036] The utility model provides a cigarette testing device, which can reduce the abnormality of detection data generated by a draw resistance detection unit, thereby improving detection efficiency.

[0037] In order to make the technical solution and advantages of the present invention more clear, the implementation methods of the present invention are described in further detail below.

[0038] refer to Figure 1 and Figure 2 The embodiment of the utility model provides a cigarette testing device, including a draw resistance detection unit 1 and a smoke guide 2. The top of the draw resistance detection unit 1 is provided with a smoke inlet 11, and the draw resistance detection unit 1 is used to detect the draw resistance of the cigarette. The smoke guide 2 is provided at the smoke inlet 11, and the smoke guide 2 is provided with a first direction (such as Figure 1 The smoke guide hole 3 (as shown in the X direction in FIG) penetrates the smoke guide member 2, and the first direction is parallel to the axial direction of the smoke inlet 11. The smoke guide hole 3 is connected to the smoke inlet 11, and the smoke guide hole 3 is used to guide the cigarette into the smoke inlet 11.

[0039] Optionally, refer to Figure 1 In this embodiment, the first direction is the vertical direction. The cigarette testing device provided by the utility model also includes a circle length detection unit 5 arranged above the smoke guide 2 along the first direction, and a smoke outlet 51 is arranged at the bottom of the circle length detection unit 5. The circle length detection unit 5 is used to detect the circumference and length of the cigarette. The cigarette output from the smoke outlet 51 can fall into the smoke guide hole 3 under the action of gravity.

[0040] The utility model sets a smoke guide 2 at the smoke inlet of the resistance to suction detection unit 1, and sets a smoke guide hole 3 on the smoke guide 2. When a cigarette is output from the smoke outlet 51 and is to enter the resistance to suction detection unit 1, the cigarette can first enter the smoke guide 2 through the smoke guide hole 3, and then under the guidance of the smoke guide 2, the cigarette can smoothly pass through the smoke inlet 11 and enter the resistance to suction detection unit 1. The utility model sets a smoke guide 2 at the smoke inlet 11, which can guide the cigarette output by the round length detection unit 5. When the cigarette has not yet been greatly skewed during the falling process, the cigarette will enter the smoke guide hole 3, and the smoke guide hole 3 can guide the cigarette into the smoke inlet 11, thereby avoiding the situation where the cigarette is too skewed during the downward movement and is difficult to enter the smoke inlet 11, thereby reducing the abnormal detection data generated by the resistance to suction detection unit 1.

[0041] Optionally, refer to Figures 1 to 4The smoke guide 2 includes a base 21 and a movable block 22. The base 21 is disposed at the smoke inlet 11. The base 21 is provided with a through hole 4 that penetrates the base 21 along a first direction. The movable block 22 is disposed in the through hole 4. The movable block 22 can move in the through hole 4 along the first direction. The smoke guide hole 3 penetrates the movable block 22 along the first direction. The utility model sets the movable block 22 so that the movable block 22 can move in the through hole 4 along the first direction to adjust the distance between the movable block 22 and the smoke outlet 51, thereby ensuring that the cigarette can enter the smoke guide hole 3, and avoiding the situation where the cigarette is too skewed during the downward movement and fails to enter the smoke guide hole 3.

[0042] Optionally, refer to Figure 4 and Figure 5 The smoke guide 2 also includes a connecting member 6, which is arranged between the base 21 and the movable block 22, and is used to lock the position of the movable block 22 in the through hole 4. Specifically, the connecting member 6 is an O-ring, and an annular groove 7 extending along the circumference of the movable block 22 is provided on the outer wall of the movable block 22, and the O-ring is arranged in the annular groove 7, and the O-ring is interference fit with the through hole 4. The utility model provides an O-ring between the base 21 and the movable block 22, and makes the O-ring and the through hole 4 interference fit, so that there is friction between the O-ring and the inner wall of the through hole 4. When the movable block 22 moves to a preset position in the through hole 4, the friction between the O-ring and the inner wall of the through hole 4 can make the movable block 22 stay at the preset position, thereby facilitating the locking of the movable block 22.

[0043] Optionally, refer to Figure 1 and Figure 6 A limiting protrusion 8 is provided on the outer wall of the base 21, and the limiting protrusion 8 is used to limit the movement of the smoke guide 2 along the first direction toward the side close to the inhalation resistance detection unit 1. A limiting block 9 is provided at the bottom of the base 21, and the limiting block 9 is inserted into the smoke inlet 11. The limiting block 9 is used to limit the radial movement of the smoke guide 2 along the smoke inlet 11. Specifically, refer to Figure 4 and Figure 6 The outer shape of the limiting block 9 is truncated cone-shaped, and the outer diameter of the limiting block 9 gradually decreases from the side close to the base 21 to the side away from the base 21.

[0044] When the smoke guide 2 needs to be installed at the smoke inlet 11, it is only necessary to insert the limit block 9 into the smoke inlet 11 and make the limit protrusion 8 clamped above the smoke inlet 11, so that the smoke guide 2 can be fixed at the smoke inlet 11 to complete the installation of the smoke guide 2. When the smoke guide 2 needs to be removed from the smoke inlet 11 to replace the smoke guide 2, the limit block 9 can be directly pulled out of the smoke inlet 11. The utility model facilitates the installation and removal of the smoke guide 2 by providing the limit protrusion 8 and the limit block 9.

[0045] Optionally, refer to Figure 1The diameter of the smoke inlet 11 gradually decreases from top to bottom, and the taper of the smoke inlet 11 is the same as the taper of the stopper 9. When the stopper 9 is inserted into the smoke inlet 11, the side wall of the stopper 9 can fit with the side wall of the smoke inlet 11, so that the relative position between the smoke guide 2 and the smoke inlet 11 can be stabilized.

[0046] Optionally, refer to Figure 1 The diameter of the cigarette guide hole 3 gradually decreases from top to bottom. This design allows the diameter of the upper opening of the cigarette guide hole 3 to be larger than the diameter of the lower opening, so that the cigarette output by the round length detection unit 5 can fall into the upper opening of the cigarette guide hole 3 more easily, which is conducive to smoothly guiding the cigarette into the draw resistance detection unit 1.

[0047] Optionally, the roughness of the side wall of the smoke guide hole 3 is 1.5-1.8. This design makes the side wall of the smoke guide hole 3 relatively smooth, and when the smoke guide hole 3 guides the cigarette toward the smoke inlet 11, the cigarette can run smoothly in the smoke guide hole 3 to ensure stable running of the cigarette.

[0048] Optionally, the smoke guide 2 is made of aluminum alloy, which has good processing properties, making the smoke guide 2 easy to process.

[0049] 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.
