Detailed Description
In this application, it is to be understood that terms such as "including" or "having" are intended to indicate the presence of the disclosed features, numbers, steps, acts, components, parts, or combinations thereof, and are not intended to preclude the presence or addition of one or more other features, numbers, steps, acts, components, parts, or combinations thereof.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
The application is further described with reference to examples of embodiments shown in the drawings.
As shown in fig. 1, an embodiment of the present application provides a device for testing performance of a cooling material, which includes a flue gas circulation pipeline 1, a heating element (not shown), and an air extractor (not shown); the heating element is used for heating the smoking material placed on the inner side of the front end region of the first pipeline 11, and the air extracting device is used for extracting air from the tail end of the second pipeline 12 so as to simulate the suction action; a first through hole 115 is provided on the pipe wall at a position near the front of the middle section of the flue gas circulation pipeline 1, and a second through hole 120 is provided on the pipe wall at a position near the rear of the middle section of the flue gas circulation pipeline.
Smoking material can be placed to the front end of flue gas circulation pipeline 1, and the tested cooling material can be placed to the position between first through-hole 115 and the second through-hole 120, and the filter tip can be placed to the end of flue gas circulation pipeline 1, so can simulate the heating and do not burn the real smoking environment of a cigarette.
Specifically, the heating element may be needle-shaped, and then the heating element is directly inserted into the smoking material from the air inlet 111 of the smoke circulation pipeline 1, and at this time, the inner diameter of the smoke circulation pipeline 1 may be the same as the actual smoking section for heating the non-burning cigarettes.
Specifically, the heating element may also be annular, so that the heating element enters the smoke circulating pipeline 1 from the air inlet 111 of the smoke circulating pipeline 1 and is sleeved outside the smoking material, and at this time, the inner diameter of the smoke circulating pipeline 1 should be larger than the diameter of the smoking section of the real cigarette which is not burned when being heated.
The suction device is used to simulate real suction action, for example, suction is performed every 20s, and the number of times of suction can be set to 8 times.
In addition, the temperature measuring element can be inserted into the smoke circulation pipeline 1 through the first through hole 115 and the second through hole 120 respectively, and the temperature of smoke generated by the smoke generating material before entering the cooling material and after flowing out of the cooling material is measured, so that the performance of the cooling material can be analyzed through the difference of the two temperatures, and the whole test process is simple and convenient to operate.
The flue gas circulation pipeline 1 can be a straight pipe as a whole or a bent pipe locally. Of course, to better simulate the actual heated non-burning cigarettes, the smoke flow line 1 is preferably a straight pipe.
The front and rear ends in this application are relative to the direction of flow of the smoke. Obviously, either end can be the front end if the flue gas flow line 1 is symmetrical. According to the current view of each drawing, the smoke flows from left to right, so the left side is front and the right side is back. For example, the left opening in fig. 2 is the air inlet 111, and the right opening is the air outlet 122.
The inner diameter of the flue gas circulation pipeline 1 can be uniform or can be arranged in different sections. In order to better simulate the actual heating of the non-burning cigarettes, the inner diameter of the smoke circulating pipeline 1 is preferably set independently in regions.
If the inner diameter of the flue gas circulation pipeline 1 is not uniform, the realization mode has various modes. The flue gas flow line 1 is formed, for example, by means of segmented splicing or by means of 3D printing. If 3D printing is selected, the material of the smoke passage 1 is, for example, acrylonitrile-butadiene-styrene (ABS) resin.
Optionally, referring to fig. 2, the flue gas circulation pipeline 1 includes a first pipeline 11 and a second pipeline 12, a tail end of the first pipeline 11 communicates with a front end of the second pipeline 12, the first pipeline 11 is detachably and fixedly connected to the second pipeline 12, a first through hole 115 is disposed on a middle pipe wall of the first pipeline 11, and a second through hole 120 is disposed on a middle pipe wall of the second pipeline 12.
The first pipeline 11 and the second pipeline 12 are connected by, for example, a snap connection, a threaded connection, or a socket connection. In fig. 2, the inner diameter of the front end of the second pipeline 12 is slightly larger than that of the rear end of the first pipeline 11, so that the two pipelines can be conveniently sleeved. Therefore, the cooling material is convenient to take and place.
Optionally, the first circuit 11 comprises: the pipeline comprises a first straight pipe 112, a second straight pipe 113 and a third straight pipe 114 which are sequentially communicated, wherein one end, far away from the first straight pipe 112, of the third straight pipe 114 is used as the tail end of the first pipeline 11, and a first through hole 115 is formed in the second straight pipe 113; the inner diameter of the second straight pipe 113 is smaller than that of the third straight pipe 114, and the inner diameter of the second straight pipe 113 is smaller than that of the first straight pipe 112.
The second straight tube 113 is of relatively small internal diameter so as to simulate the airflow path between the smoking material and the cooling material in a real heated non-burning cigarette, which is relatively thin.
Optionally, the first pipeline 11 is of an integrally formed structure. Thus, air leakage can be reduced and the processing is convenient.
Optionally, the second circuit 12 comprises: a fifth straight pipe 117, a sixth straight pipe 118 and a seventh straight pipe 119 which are communicated in sequence, wherein one end, far away from the sixth straight pipe 118, of the fifth straight pipe 117 serves as the front end of the second pipeline 12, and a second through hole 120 is formed in the sixth straight pipe 118; the inner diameter of the sixth straight pipe 118 is larger than that of the seventh straight pipe 119.
The seventh straight pipe 119 can be used for placing tow filter sticks, and the sixth straight pipe 118 is a tubular space simulating the front ends of the tow filter sticks in real cigarette which is not heated and combusted. The tubular space serves for the damping of the hot fumes. Also to simulate a real pumping environment.
Optionally, the fifth straight tube 117 has an inner diameter greater than the outer diameter of the end of the first pipeline 11. This is for convenience of the second pipe 12 being fitted to the first pipe 11. The gap between the two can be sealed by using raw adhesive tape.
Optionally, the second conduit 12 is of unitary construction. Thus, the sealing performance is increased and the production process is simplified.
Optionally, the method further comprises: a fourth straight tube 116 in communication with the first through hole 115 and/or an eighth straight tube 121 in communication with the second through hole 120.
When a temperature measuring element such as a thermocouple is used, the length of the thermocouple is usually long, even when the thermocouple is inserted into the first pipeline 11 or the second pipeline 12, a part of the thermocouple is still exposed out of the first pipeline 11 or the second pipeline 12, and the fourth straight-through and the eighth straight-through can ensure that the thermocouple is not exposed to the outside, so that the temperature measurement is more accurate.
In a specific example, referring to FIG. 2, the parameters of a partially straight tube are as follows.
Optionally, referring to fig. 3, the temperature measuring device further comprises a first temperature measuring element 21a, a second temperature measuring element 21b and a recording device 22, wherein the first temperature measuring element 21a is inserted into the first pipeline 11 from the first through hole 115 and is used for measuring the temperature of the gas in the first pipeline 11, the second temperature measuring element 21b is inserted into the second pipeline 12 from the second through hole 120 and is used for measuring the temperature of the gas in the second pipeline 12, and the recording device 22 is used for continuously recording the temperature measured by the first temperature measuring element 21a and the temperature measured by the first temperature measuring element 21 a.
The tail end of the temperature measuring element can be arranged on the central axis of the pipeline, so that the central temperature of the smoke can be better sensed. The temperature measuring element is, for example, a thermocouple, a thermal resistor, a thermistor, or the like.
The actual workflow is, for example: firstly, the temperature measuring element is started to measure the temperature, then the heating element and the air extractor are started, and the temperature of the smoke before passing through the temperature reducing material and the temperature of the smoke after passing through the temperature reducing material are recorded.
Referring to fig. 4, in one specific example, a temperature profile of the smoke is recorded. It can be seen that the cooling material has an obvious cooling effect on the temperature of the smoke.
The embodiments in the present application are described in a progressive manner, and the same and similar parts among the embodiments can be referred to each other, and each embodiment focuses on the differences from the other embodiments.
The protective scope of the present application is not limited to the above-described embodiments, and it is apparent that various modifications and variations can be made to the present application by those skilled in the art without departing from the scope and spirit of the present application. It is intended that the present application also include such modifications and variations as come within the scope of the appended claims and their equivalents.
