Hyperboloid rotary seal's heating smoking setTechnical Field
The invention belongs to the field of novel cigarette smoking sets, and particularly relates to a hyperboloid rotary seal heating smoking set.
Background
The traditional cigarette releases nicotine and aroma components in tobacco in a combustion mode, so that the requirements of consumers are met. The heating cigarette is to heat the tobacco product to the atomization temperature by an external heat source, so as to achieve the effect of generating smoke. And the heating temperature is lower than the combustion temperature of the tobacco, so that a large amount of harmful substances generated by the combustion of the cigarettes can be obviously reduced, and the harm of second-hand smoke to non-smoking people is reduced.
Because the heating temperature of the heated cigarette is lower than the burning temperature, compared with the traditional cigarette, the tobacco aroma components of the heated cigarette are difficult to completely release, and the smoke quantity is insufficient, so that the cigarette is difficult to be accepted by traditional smokers. If the bottom of the cigarette is sealed, the oxygen content is reduced along with the heating process (due to the replacement effect of the fresh smoke in the process on the internal atmosphere), at this time, even if the heating temperature is increased, the combustion phenomenon is not generated, and the release of the tobacco aroma components can be increased.
However, if the bottom of the cigarette is sealed in the preparation of the cigarette, the existing cigarette production process is greatly changed, and the equipment cost is too high. It is desirable to develop a simple and economical method for achieving bottom sealing of cigarettes.
Meanwhile, in order to ensure the insertion of cigarettes, the inner diameter of the existing cigarette accommodating cavity is larger than the outer diameter of the cigarettes, gaps generally exist between the cigarette accommodating cavity and the cigarettes, connection is not tight, and the cigarettes are easy to drop.
The present invention has been made to solve the above-described problems.
Disclosure of Invention
The present invention has been made to solve the above-described problems.
The first aspect of the invention provides a hyperboloid rotary sealed heating smoking set, which comprises a deformable cigarette accommodating cavity 2 and a heating element fixing seat 3;
Wherein the heating element fixing seat 3 comprises a hollow first truncated cone and is sealed at the bottom;
The cigarette accommodating cavity 2 comprises a hollow second truncated cone, the second truncated cone is at least partially arranged inside the first truncated cone, the second truncated cone and the first truncated cone are connected by virtue of threads on conical surfaces of the second truncated cone and the first truncated cone, and at least one vertical groove 203 penetrating through the bottom of the second truncated cone and the conical wall is arranged on the conical surface of the bottom of the second truncated cone;
the smoking set is also provided with a rotation mechanism which can drive the second truncated cone to rotate along the thread;
The vertical groove 203 is in a free extending state when the second truncated cone and the first truncated cone are in a first threaded position, the cigarette accommodating cavity 2 is provided with a first minimum inner diameter, and the vertical groove 203 is in a contracted and closed state when the second truncated cone and the first truncated cone are in a second threaded position, and the cigarette accommodating cavity 2 is provided with a second minimum inner diameter.
The heating element fixing seat 3 is made of food-grade metal materials (such as SUS 304) or special food-grade high-temperature buying materials (such as PEEK).
Preferably, the outer conical surface of the second truncated cone is provided with an external thread 202, and the inner conical surface of the first truncated cone is provided with an internal thread 301 adapted to the external thread 202.
Preferably, the vertical groove 203 is not coincident with the threaded connection.
Preferably, the smoking set further comprises a heating element 4, which is arranged at the periphery or inside the heating element fixing seat 3.
Preferably, the design of the rotation mechanism is as follows:
The smoking set further comprises a rotatable upper shell 1 which is arranged outside the cigarette accommodating cavity 2 and is connected with the cigarette accommodating cavity 2. When the upper shell 1 rotates, the upper shell drives the cigarette accommodating cavity 2 to rotate.
Preferably, the heating element fixing seat 3 is integrally connected with the heating element 4, and the shape of the heating element 4 comprises a needle shape, a sheet shape or a hollow truncated cone shape.
Preferably, the connection mode comprises jack connection, gear connection and magnetic attraction connection.
Preferably, the jack connection mode is as follows:
At least one boss 101 is arranged in the upper shell 1, at least one hole 201 matched with the boss 101 is arranged at the upper part of the cigarette accommodating cavity 2, and the hole 201 penetrates through the boss 101.
The threaded connection of the second truncated cone and the first truncated cone of the present invention is designed such that the minimum inner diameter of the vertical groove 203 after shrinkage and drawing together is smaller than the outer diameter of the cigarette when the second truncated cone is rotated to the bottom of the first truncated cone.
When the heating element fixing seat 3 is fixed, the rotation mechanism drives the second truncated cone of the cigarette accommodating cavity 2 to automatically pass, and the conical surfaces of the second truncated cone and the first truncated cone are of conical surface structures and are connected through threads, so that the cigarette accommodating cavity 2 rotates and moves downwards, at the moment, the heating element fixing seat 3 can extrude the cigarette accommodating cavity 2, the vertical groove 203 of the cigarette accommodating cavity 2 contracts and is closed, and the minimum inner diameter of the cigarette accommodating cavity 2 is reduced. When the cigarettes are inserted, the cigarettes are extruded by the cigarette accommodating cavity 2 after being gathered, a closed space is formed among the bottoms of the cigarette accommodating cavity 2, the cigarettes and the bottoms of the heating element fixing seats 3, and tobacco segments of the cigarettes are sealed.
The using method of the smoking set is as follows:
The rotation mechanism is used for driving the second truncated cone of the cigarette accommodating cavity 2 to rotate and simultaneously move downwards, when the second truncated cone and the first truncated cone are in a threaded connection second position, the vertical groove 203 is in a contracted and closed state, and the cigarette accommodating cavity 2 has a second minimum inner diameter. And stopping the rotation of the rotation mechanism when the second minimum inner diameter is slightly smaller than the outer diameter of the cigarette after the cigarette moves downwards. The cigarettes are inserted into the cigarette accommodating cavity 2, the cigarettes are extruded by the cigarette accommodating cavity 2 after being gathered, a closed space is formed among the bottoms of the cigarette accommodating cavity 2, the cigarettes and the bottoms of the heating element fixing seats 3, and tobacco segments of the cigarettes are sealed.
The technical proposal can be freely combined on the premise of no contradiction.
The invention has the following beneficial effects:
1. The invention adopts a hyperboloid structure formed by the second truncated cone and the first truncated cone for the first time, and designs a smoking set with a changeable minimum inner diameter of a cigarette accommodating cavity. When the smoking set is used together with a general cigarette, the smoking set can play a role in fixing cigarettes and prevent the cigarettes from falling from the cigarette accommodating cavity. When the cigarette is matched with the oxygen-deficient heating type cigarette, the bottom of the cigarette accommodating cavity and the bottom of the heating element fixing seat can seal the tobacco section of the cigarette, the oxygen-deficient heating type cigarette does not need to independently prepare the sealed tobacco section, and the preparation process of the cigarette is simplified.
2. Because the minimum internal diameter of the cigarette accommodating cavity is variable, one cigarette can be matched with cigarettes with various diameters, and the best clamping and sealing effects can be achieved.
