Description

Technical Field

[0001] The present invention relates to the field of cigarette smoke evaluation, and more particularly to an evaluation device for cigarette sidestream smoke. Background Art

[0002] When cigarettes burn, they produce two main types of smoke: mainstream smoke, drawn from the filter tip during inhalation, and sidestream smoke, which is released from the burning tip and diffuses through the cigarette paper directly into the environment. Sidestream smoke, when released into the air, not only pollutes the environment but also creates discomfort for those around it with its unpleasant odor. In recent years, with the growing global anti-smoking movement, the issue of "secondhand smoke" has garnered widespread attention.

[0003] To alleviate the conflict between smokers and passive smokers, technical measures to improve the comfort of sidestream smoke, such as applying flavors and fragrances to improve the sidestream smoke atmosphere, can be studied. However, the first challenge to be solved is how to prevent the rapid dilution and diffusion of cigarette sidestream smoke in the environment and accurately and reproducibly collect and evaluate the odor of sidestream smoke.

[0004] Currently, well-established smoke capture and detection equipment for the chemical composition of sidestream smoke exists. These typically involve a fishtail hood placed above the smoke generator of a smoking machine, with the end of the hood connected to a suction device to capture sidestream smoke aerosols. However, during actual smoking, sidestream smoke first diffuses into the atmosphere before entering the nasal cavity and being perceived by the human body. Existing equipment is limited to capturing and chemically analyzing sidestream smoke components and is not suitable for sensory evaluation.

[0005] Therefore, how to provide a device suitable for sensory evaluation of sidestream smoke has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

DETAILED DESCRIPTION

[0032] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0035] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0036] like Figure 1 and Figure 2 As shown, the device for evaluating cigarette sidestream smoke disclosed herein includes a base 1 and a cover 2 .

[0037] The base 1 includes a base body 11, a filter holding mechanism 12 and a cigarette holding mechanism 13. The base body 11 is provided with an assembly portion 111 and an air vent 112. The filter holding mechanism 12 and the cigarette holding mechanism 13 are both mounted on the base body 11. The filter holding mechanism 12 is used to clamp the Cambridge filter, and its structure may be, for example, a rod-shaped or block-shaped structure. The cigarette holding mechanism 13 is used to clamp and fix cigarettes so that a device such as a pump with a suction function can inhale the cigarettes clamped and fixed on the cigarette holding mechanism 13. The cigarette holding mechanism 13 may have a tubular structure.

[0038] The cover body 2 includes a cover body main body 21 and an exhaust mechanism 22. The cover body main body 21 is provided with a mounting portion 210 and an exhaust window (not shown in the figure). The mounting portion 210 cooperates with the assembly portion 111 to install the cover body 21 on the base body 11. The cooperation between the mounting portion 210 and the assembly portion 111 can be achieved in a variety of ways. For example, the mounting portion 210 and the assembly portion 111 are threadedly matched. For another example, the mounting portion 210 and the assembly portion 111 are snap-fitted, etc. It should be noted that in a specific implementation, the cooperation between the mounting portion 210 and the assembly portion 111 should be airtight so as to more accurately perform a sensory evaluation of the sidestream smoke.

[0039] The exhaust mechanism 22 cooperates with the exhaust window to adjust the size of the opening connecting the exhaust window to the outside world. The exhaust mechanism 22 can have a cap-like or plug-like structure. By adjusting the coordination between the exhaust mechanism 22 and the exhaust window (e.g., the angle of engagement), the area connecting the exhaust window to the outside world can be adjusted. In practice, the area connecting the exhaust window to the outside world can be adjusted as needed. For example, the area connecting the exhaust window to the outside world can be adjusted based on the size of the cigarette.

[0040] The housing 21 and the base 11 form an air cavity. The air holes 112 and the exhaust window are both connected to the air cavity. The filter and the cigarette are both located in the air cavity.

[0041] The filter clamping mechanism 12 and the cigarette clamping mechanism 13 extend from the base body 11 toward the top end of the cover body 21, and the height of the filter clamped by the filter clamping mechanism 12 relative to the base body 11 is greater than the height of the cigarette clamped by the cigarette clamping mechanism 13 relative to the base body 11, and the height of the exhaust window relative to the base body 11 is greater than the height of the filter clamped by the filter clamping mechanism 12 relative to the base body 11.

[0042] The device for evaluating cigarette sidestream smoke disclosed herein can be used in the following manner:

[0043] 1. Clamp a Cambridge filter disc (1) soaked in mineral oil onto the filter holder (12). Clamp a cigarette (24.3 mm circumference) into the cigarette holder (13). Light the cigarette and install the housing (21) onto the base (11). When the cigarette is burned to the 1 / 3 of the filter end, remove the Cambridge filter disc and perform a sniff evaluation.

[0044] 2. Clamp the Cambridge filter soaked in mineral oil on the filter clamping mechanism 12, and clamp the cigarette (circumference 24.3mm or circumference 17.0mm or circumference 20.0mm) in the cigarette clamping mechanism 13. Connect the peristaltic pump through a hose to suck the cigarette. The peristaltic pump parameters are as follows: single-puff duration is 2s, the suction capacity is 35mL, and the suction frequency is one puff every 60s. Light the cigarette and start the peristaltic pump, and install the cover body 21 on the base body 11. When the set number of puffs is reached, take out the Cambridge filter and perform a filter sniffing evaluation.

[0045] 3. Remove the exhaust mechanism 22 installed on the exhaust window and clamp the cigarette (circumference 24.3mm) in the cigarette clamping mechanism 13. Connect a peristaltic pump via a hose to draw the cigarette. The peristaltic pump parameters are as follows: single-puff duration of 2s, suction volume of 35mL, and suction frequency of one puff every 60s. Light the cigarette and start the peristaltic pump. Install the cover body 21 on the base body 11. When the set number of puffs is reached, directly smell the smoke at the exhaust window for olfactory evaluation.

[0046] The disclosed device for evaluating cigarette sidestream smoke can perform sensory evaluation of sidestream smoke after it has diffused, effectively assessing the impact of sidestream smoke during actual smoking. Furthermore, evaluators can perform olfactory evaluation using a Cambridge filter held by the filter holder 12 or olfactory evaluation using the exhaust window and exhaust mechanism 22, as needed, thereby improving the accuracy of sensory evaluation of sidestream smoke.

[0047] In one embodiment of the cigarette sidestream smoke evaluation device disclosed herein, in order to simplify the structure of the cigarette sidestream smoke evaluation device, the assembly portion 111 is an annular groove located on the side wall of the base body 11, and the mounting portion 210 is the bottom end surface of the cover body 21.

[0048] In one embodiment of the device for evaluating cigarette sidestream smoke disclosed herein, in order to effectively improve the air permeability of the air cavity, the air holes 112 are evenly distributed in an array on the base body 11 .

[0049] In one embodiment of the device for evaluating cigarette sidestream smoke disclosed herein, the filter holding mechanism 12 includes a filter holding rod. A filter holding slot (not shown) is provided at the top of the filter holding rod. The filter holding slot facilitates quick and easy clamping of Cambridge filters.

[0050] Furthermore, the cigarette holding mechanism 13 includes a cigarette sleeve 131 and a cigarette sleeve support 132. The cigarette sleeve 131 extends perpendicularly to the direction of extension of the filter clamping rod. The cigarette sleeve 131 is mounted on the base body 11 via the cigarette sleeve support 132. This structure of the cigarette holding mechanism 13 is simple and allows for quick and easy securing of cigarettes.

[0051] In order to improve the accuracy of sensory evaluation of sidestream smoke, the exhaust window can be set corresponding to the cigarette sleeve 131, that is, the exhaust window and the cigarette sleeve 131 are located on the same side of the air cavity.

[0052] Furthermore, the cigarette holding mechanism 13 also includes a connecting tube 133 and an air pump (not shown). The connecting tube 133 is connected to the cigarette sleeve 131. The air pump can be used to extract air from the cigarette held in the cigarette sleeve 131. The air pump can be, for example, a peristaltic pump.

[0053] Furthermore, to improve the accuracy of sensory evaluation of sidestream smoke, the filter clamping rod and the cigarette sleeve bracket 132 are mounted on the same plane on the base body 11. The distance between the cigarette sleeve 131 and the filter clamping rod is 1.2-1.5 times the difference between the distance between the filter clamping groove and the base body 11 and the distance between the cigarette sleeve 131 and the base body 11.

[0054] In one embodiment of the device for evaluating cigarette sidestream smoke disclosed herein, to improve the accuracy of sensory evaluation of sidestream smoke, the exhaust mechanism 22 is an exhaust cover. The exhaust cover is rotationally engaged with the exhaust window. This rotational engagement can be achieved through a clearance fit or a threaded fit.

[0055] The exhaust cover is provided with a first exhaust hole 221 and a second exhaust hole 222. The area of ​​the first exhaust hole 221 is larger than the area of ​​the second exhaust hole 222.

[0056] The exhaust window is provided with a third exhaust hole and a fourth exhaust hole. The area of ​​the third exhaust hole is larger than that of the fourth exhaust hole, and the area of ​​the third exhaust hole is larger than that of the first exhaust hole 221, and the area of ​​the fourth exhaust hole is larger than that of the second exhaust hole 222.

[0057] When the device for evaluating cigarette sidestream smoke is used for filter sniffing evaluation, the first and third exhaust holes at least partially overlap, while the second and fourth exhaust holes are blocked. When the exhaust cover is rotated to a certain angle relative to the exhaust window, the second exhaust hole 222 corresponds to the non-perforated area of ​​the exhaust window excluding the third and fourth exhaust holes, while the fourth exhaust hole corresponds to the non-perforated area of ​​the exhaust cover excluding the first and second exhaust holes 221, 222, thereby blocking the second and fourth exhaust holes.

[0058] In a specific implementation, during the process of performing the filter olfactory evaluation, the third exhaust hole can completely cover the first exhaust hole 221, so that the first exhaust hole 221 is in a fully open state.

[0059] When the device for evaluating cigarette sidestream smoke is used for direct sniff evaluation, the second exhaust hole 222 and the fourth exhaust hole at least partially overlap, and the first exhaust hole 221 and the third exhaust hole are blocked. When the exhaust cover is rotated to a certain angle relative to the exhaust window, the first exhaust hole 221 corresponds to the non-perforated area of ​​the exhaust window other than the third and fourth exhaust holes, and the third exhaust hole corresponds to the non-perforated area of ​​the exhaust cover other than the first and second exhaust holes 221, 222, thereby blocking the first and third exhaust holes.

[0060] In a specific implementation, during the direct olfactory evaluation, the fourth exhaust hole can completely cover the second exhaust hole 222, so that the second exhaust hole 222 is in a fully open state.

[0061] Furthermore, the first exhaust hole 221 is fan-shaped, and the second exhaust hole 222 is a circular hole.

[0062] In one embodiment of the evaluation device for cigarette sidestream smoke disclosed herein, in order to improve the accuracy of the sensory evaluation of sidestream smoke, the height of the exhaust window relative to the base body 11 is 1.2-1.5 times the height of the filter clamped on the filter clamping mechanism 12 relative to the base body 11.

[0063] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
