Technical Field

The invention belongs to the field of novel cigarette smoking sets, and particularly relates to a heating smoking set with double curved surface rotary sealing.

Background

The traditional cigarette releases nicotine and flavor components in tobacco in a combustion mode, and meets the requirements of consumers. The cigarette is heated to the atomizing temperature by an external heat source to achieve the effect of generating smoke. And the heating temperature is lower than the combustion temperature of tobacco, so that a large amount of harmful substances generated by the combustion of the cigarette can be remarkably 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 combustion 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 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 fresh smoke on the internal atmosphere), and at the moment, even if the heating temperature is increased, the combustion phenomenon can not occur, and the release of the tobacco aroma components can be increased.

However, if the bottom of the cigarette is sealed in the cigarette preparation process, 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 sealing the bottom of a cigarette.

Simultaneously, in order to guarantee the insertion of cigarette, current cigarette holds the intracavity footpath and is greater than the external diameter of cigarette, and the cigarette holds and generally has the space between chamber and the cigarette, connects inseparably, causes the dropping of cigarette easily.

The present invention has been made to solve the above problems.

Disclosure of Invention

The present invention has been made to solve the above problems.

The invention provides a hyperboloid rotary sealing 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 frustum body, and the bottom of the hollow first frustum body is sealed;

the cigarette accommodating cavity 2 comprises a hollow second truncated cone, at least part of the second truncated cone is arranged in the first truncated cone and is connected with the first truncated cone through threads on the conical surface of the second truncated cone, and at least one vertical groove 203 penetrating through the bottom and the conical wall of the second truncated cone is formed in the conical surface of the bottom of the second truncated cone;

the smoking set is also provided with a rotation actuating mechanism which can drive the second frustum to rotate along the thread; the cone is a cone;

when the second truncated cone and the first truncated cone are in a first position of threaded connection, the vertical groove 203 is in a free extension state, and the cigarette accommodating cavity 2 has a first minimum inner diameter; when the second truncated cone and the first truncated cone are in the second position of threaded connection, the vertical groove 203 is in a contraction and gathering state, 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 material (such as SUS304) or special food-grade high-temperature material (such as PEEK).

Preferably, the external conical surface of the second truncated cone is provided with an external thread 202, and the internal conical surface of the first truncated cone is provided with an internal thread 301 matched with the external thread 202.

Preferably, the vertical slots 203 do not coincide with the threaded connection.

Preferably, the smoking set further comprises a heating element 4 arranged at the periphery or inside of the heating element fixing seat 3.

Preferably, the actuator is designed as follows:

but the smoking set still includes the epitheca 1 of rotation, and it sets up the cigarette holds the chamber 2 outside, with the cigarette holds the chamber 2 and connects. 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 inside the upper shell 1, at least one hole 201 matched with the boss 101 is formed in the upper portion 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 invention is designed such that: when the second truncated cone rotates to the bottom of the first truncated cone, the minimum inner diameter of the contracted and gathered vertical groove 203 is smaller than the outer diameter of the cigarette.

When heating element fixing base 3 is fixed, send slewing mechanism to drive the cigarette and hold the second truncated cone body of chamber 2 when passing by, because the conical surface of second truncated cone body and first truncated cone body is the conical surface structure, and through threaded connection, so the cigarette also can move down when holding chamber 2 pivoted, heating element fixing base 3 can extrude the cigarette and hold chamber 2 this moment, and the cigarette holds the shrink of the perpendicular groove 203 of chamber 2, closes up, and the cigarette minimum internal diameter that holds chamber 2 diminishes. When inserting a cigarette, the cigarette after closing holds chamber 2 and can extrudees a cigarette, and the cigarette holds 2 bottoms in chamber, a cigarette and will form an airtight space between 3 bottom three of heating element fixing base, sealed cigarette's tobacco section.

The using method of the smoking set comprises the following steps:

use it moves down when actuating the second truncated cone body that the mechanism drove cigarette and hold chamber 2 rotates, second truncated cone body and first truncated cone are in threaded connection's second position, perpendicular groove 203 is for the shrink state of closing together, cigarette holds chamber 2 and has the minimum internal diameter of second. When the cigarette is moved downwards to the second minimum inner diameter which is slightly smaller than the outer diameter of the cigarette, the rotation of the rotation actuating mechanism is stopped. Cigarette holds and to insert cigarette in the chamber 2, and the cigarette that closes up holds chamber 2 and can extrude cigarette, and the cigarette holds and will form an airtight space, sealed cigarette's tobacco section between chamber 2 bottom, cigarette and 3 bottom three of heating element fixing base.

The technical scheme can be freely combined on the premise of no contradiction.

The invention has the following beneficial effects:

1. the invention designs a smoking set with a cigarette accommodating cavity with a variable minimum inner diameter by adopting a hyperboloid structure formed by a second truncated cone and a first truncated cone for the first time. When the smoking set is used in cooperation with a common cigarette, the smoking set can play a role in fixing the cigarette and prevent the cigarette from falling from the cigarette accommodating cavity. When the smoking set is used in cooperation with the oxygen-deficient heating type cigarette, the tobacco section of the cigarette can be sealed at the bottom of the cigarette accommodating cavity and the bottom of the heating element fixing seat, and the oxygen-deficient heating type cigarette does not need to be independently prepared with the sealed tobacco section, so that the preparation process of the cigarette is simplified.

2. Because the minimum inner diameter of the cigarette accommodating cavity is variable, one smoking set can be adapted to cigarettes with various diameters, and the best clamping and sealing effects can be achieved.
