TECHNICAL FIELD

[0001] The present application relates to the technical field of heating cigarette detection, in particular to a heating cigarette dynamic resistance detection device. BACKGROUND

[0002] Traditional cigarettes are harmful to human health due to the combustion and pyrolysis of a large amount of harmful substances. As a new type of tobacco, heating cigarettes have a lower working temperature and produce much less harmful components in the smoke than traditional cigarettes, greatly reducing the adverse effects of cigarettes on human health. Therefore, heating cigarette products have become the current research focus.

[0003] Currently, the smoking modes and parameters commonly used by smoking machines in most countries are mainly the smoking modes defined by the International Organization for Standardization (ISO), the Canadian deep puffing mode and the Massachusetts puffing mode. The ISO puffing mode is to puff 35mL per puff, 2s per puff, and 1 puff every 60s. The Canadian deep puffing mode is to puff 55mL per puff, 2s per puff, and 30s between puffs. The Massachusetts puffing mode is to puff 45mL per puff, 2s per puff, and 30s between puffs. Under the premise of the urgent need for heating cigarettes to be widely marketed, it has become the current research focus to develop a device that can meet the dynamic resistance detection of heating cigarettes and ensure its detection accuracy and adaptability. The existing dynamic resistance detection device for heating cigarettes can only be used for specific models of heating devices, and the negative pressure suction conditions generated are not convenient to adjust, which cannot meet the detection of various models of heating devices and different puffing modes, and the scope of application is narrow.

[0030] Figure 5 yes Figure 4 Structural cross-section of line AA in the middle. Detailed Implementation

[0031] See attached document Figure 1 As shown, the dynamic suction resistance detection device for heated cigarettes in this embodiment includes a cabinet 1 and a heated cigarette clamping mechanism 2, a heated cigarette holder 3, and a suction cylinder mechanism (located inside the cabinet, not shown in the figure) fixed on the cabinet 1.

[0032] In this embodiment, the heating fume clamping mechanism 2 is fixed to the upper part of the cabinet panel and is used to clamp the heating fume 10. (See attached diagram) Figure 2 As shown, the heating appliance clamping mechanism 2 includes a square clamp frame 21 and two movable clamps 22 movably connected to the square clamp frame 21. Each movable clamp 22 includes two clamping plates 221 located on both sides of the square clamp frame 21, a connector 222 fixed between the two clamping plates 221, and a locking screw 223 connected to the connector 222. The locking screw 223 is threaded through a threaded hole 211 on one side of the square clamp frame 21. The two movable clamps 22 are arranged opposite to each other, and the distance between the two movable clamps 22 is adjusted by adjusting the threads of the two locking screws 223, thereby clamping and releasing the heating appliance 10 placed therein. For example, by adjusting any one or both locking screws 223 simultaneously, moving them towards the center of the square clamp frame 21, the heating appliance 10 is clamped. Conversely, the heating appliance 10 can be released. By adjusting the two movable clamps 22, the heating device 10 can be clamped and released, and its clamping position within the square clamp frame 21 can also be adjusted to ensure alignment between the cigarette inlet of the heating device 10 and the clamping port of the heated cigarette holder 3. Alternatively, one of the movable clamps 22 can be fixed, allowing the heating device to be clamped and released using only one movable clamp.

[0033] In a preferred embodiment, the clamping plates 221 of the two movable clamps 22 are both provided with V-shaped groove structures 224 on opposite sides. This facilitates the clamping and fixing of the heated tobacco device 10, preventing displacement after clamping, and also allows it to adapt to heated tobacco devices 10 of different shapes and sizes. Simultaneously, it ensures that the working centers of the heated tobacco device 10 are at the same height when clamped, so that the center of the cigarette inlet of the heated tobacco device 10 is concentric with the clamping port of the heated cigarette holder 3. The included angle of the V-shaped groove structure 224 is preferably set to 120-150°, such as 135° being optimal.

[0034] In order to further expand the horizontal adjustment range of the heating appliance, the heating appliance clamping mechanism 2 also includes a fixing plate 23. The fixing plate 23 has an elongated slot 231 with the same orientation as the square clamp frame 21. The bottom of the square clamp frame 21 has a through hole with an adjusting screw 225. The adjusting screw 225 is fixed in the position of the elongated slot 231, which can be used to adjust the position of the square clamp frame 21 on the fixing plate 23, further expanding the horizontal adjustment range of the heating appliance.

[0035] In order to adjust the wrapping depth of the heated cigarette, two straight rails 24 are arranged on the cabinet panel in parallel, and a sliding block 25 is arranged on each of the straight rails 24, and the lower part of the fixed plate 23 is fixedly connected with the sliding blocks 25 of the two straight rails 24. The moving direction of the fixed plate 23 along the straight rails 24 is perpendicular to the slotting direction of the long slot hole 231 on the fixed plate 23, so that the fixed plate 23 and the square clamp frame 21 are moved forward and backward relative to the heated cigarette holder 3 by the sliding blocks 25 moving on the straight rails 24, so as to adjust the wrapping depth of the heated cigarette.

[0036] In addition, the lower part of the fixed plate 23 is further fixed with a rail clamp 26 for locking and releasing the position of the fixed plate 23 on the straight rails 24. The rail clamp 26 is a hand wheel type rail clamp. After the position of the fixed plate 23 is adjusted to the right position, the rail clamp is locked by the hand wheel type rail clamp, so as to fix the front and back positions of the heated cigarette holder 2. When the front and back positions of the heated cigarette holder 2 need to be adjusted, the rail clamp is released by the hand wheel type rail clamp, so that the position of the heated cigarette holder 2 can be simply and conveniently adjusted to adapt to the dynamic resistance detection of different heated cigarettes.

[0037] In the embodiment, the heated cigarette holder 3 is fixed on the upper part of the cabinet panel, and is a labyrinth ring type holder. Referring to FIG. 2, Figure 4 and 5 As shown in the figure, one end of the labyrinth ring type holder is a mouthpiece sealing and clamping port 31, and the other end is a negative pressure interface 32. The mouthpiece sealing and clamping port 31 is arranged corresponding to the cigarette inlet of the heated cigarette holder 10. The inside of the mouthpiece sealing and clamping port 31 is provided with a gasket 311 and four sealing rings 312. The four sealing rings 312 are installed in the order of positive-positive-positive-negative, and can seal the mouthpiece of the heated cigarette. In addition, the sealing ring 312 has a plurality of specifications of central diameter hole types to meet the sealing requirements of heated cigarettes with different circumferences.

[0038] In the embodiment, the suction cylinder mechanism is arranged in the cabinet 1. Referring to FIG. 3, Figure 3As shown, the suction cylinder mechanism includes a suction cylinder fixing base 41, a piston cylinder base 42, a piston cylinder 43, a piston 44 and a through-type stepping motor 45. The suction cylinder fixing base 41 is fixedly connected with the cabinet panel through a connecting piece 46, and the piston cylinder base 42 is fixed on one side of the suction cylinder fixing base 41 through a connecting screw 47. The piston cylinder 43 is fixed between the suction cylinder fixing base 41 and the piston cylinder base 42, and the through-type stepping motor 45 is fixed on the other side of the suction cylinder fixing base 41. The central screw rod 451 of the through-type stepping motor 45 penetrates through the suction cylinder fixing base 41 and is connected with the piston 44, so as to realize the axial movement of the piston 44 in the piston cylinder 43 and generate negative pressure gas. The center of the piston cylinder base 43 is provided with a through hole, and a gas pipe quick connector 57 is arranged at the through hole. The gas pipe quick connector 57 is connected with the negative pressure interface 32 of the heated cigarette holder 3 through a hose, so as to realize the dynamic suction action on the heated cigarette. That is, by controlling the through-type stepping motor 45, the central screw rod 451 is moved along the axial direction, and the piston 44 is axially pulled in the piston cylinder 43, so as to generate the required negative pressure condition.

[0039] The suction cylinder mechanism further includes a guide rod 48 arranged in parallel with the central screw rod 451 of the through-type stepping motor 45, and a guide plate 49 fixedly connected with the central screw rod 451. A linear bearing 50 is movably arranged on the guide rod 48, and the linear bearing 50 is fixedly connected with the guide plate 49. The linear bearing 50 moves linearly along the guide rod 48 under the driving of the central screw rod 451 of the through-type stepping motor 45, so as to limit the radial movement of the central screw rod 451 and ensure the normal operation of the central screw rod 451.

[0040] One end of the guide rod 48 is fixed on the suction cylinder fixing base 41, and an optoelectronic support plate 51 fixed in parallel with the guide rod 48 is further arranged on the suction cylinder fixing base 41. The other end of the optoelectronic support plate 51 is fixedly connected with a guide rod fixing plate 52 connected with the other end of the guide rod 48.

[0041] The suction cylinder mechanism further includes a position detection mechanism. The position detection mechanism includes a position sensing sheet 53, a first optoelectronic sensor 54 and a second optoelectronic sensor 55. The position sensing sheet 53 is fixed on the guide plate 49, and the first optoelectronic sensor 54 and the second optoelectronic sensor 55 are respectively arranged on the optoelectronic support plate 51 in a spaced manner, and are respectively used for detecting the two end limit positions of the position sensing sheet 53 moving with the central screw rod 451, that is, adjusting the start and stop positions of the piston 44.

[0042] And, the first photoelectric sensor 54 and the second photoelectric sensor 55 are respectively fixed on the photoelectric support plate 51 through the long waist hole 56. The slotting direction of the long waist hole 56 is parallel to the axial direction of the guide rod 48, so that by adjusting the positions of the first photoelectric sensor 54 and the second photoelectric sensor 55 in the long waist hole 56, the position adjustment of the first photoelectric sensor 54 and the second photoelectric sensor 55 on the photoelectric support plate 51 and the distance adjustment between the two sensors can be realized, and then the axial movement distance adjustment of the piston 43 is realized, so as to meet the requirements of ISO, Canada deep suction and Massachusetts suction mode.

[0043] In addition, a filter sheet is arranged on the hose between the tracheal quick connector 57 and the negative pressure interface 32, so as to realize the filtration of impurities generated during the heating of the heated cigarette in the detection process, avoid the pollution of the piston cylinder 44, and improve the service life of the detection device.

[0044] The heated cigarette dynamic suction resistance detection device can realize the clamping of the heated smoking set, the heating of the heated cigarette, and the suction under different suction modes through the cooperation of the heated smoking set clamping mechanism, the heated cigarette holder and the suction cylinder mechanism, and provide strong support for the dynamic suction resistance detection and analysis in the suction process. The heated smoking set clamping mechanism can not only adapt to heated smoking sets of different shapes and sizes, but also ensure the accurate centering of the heated cigarette and the heated cigarette holder, and is simple and convenient to adjust and has a wide application range. The through-type stepping motor in the suction cylinder mechanism can directly drive the piston to move axially, and the auxiliary setting of the guide rod and the linear bearing can ensure the stable pulling action of the piston and the stability of the negative pressure gas. The setting of the position sensing mechanism can realize the adjustment of the pulling depth of the piston, and then realize the adjustment of the frequency and capacity, so as to meet the needs of different suction modes.
