Abstract

A heat-not-burn tobacco narrow-hole inhalation device, comprising a heating tube (6); a tobacco heating chamber is provided in the heating tube (6), and the inner diameter of the tobacco heating chamber of the heating tube (6) is larger than the outer diameter of a cigarette inserted; one end of the heating tube is a cigarette insertion opening (3), and the other end is a cigarette removal opening (7); the diameter of the cigarette removal opening (7) is smaller than the diameter of the cigarette; air enters from the position of the cigarette removal opening (7) and flows out of the cigarette insertion opening (3); the cigarette is inserted into the heating tube (6) from the cigarette insertion opening (3); air flows along the central axis inside the cigarette and smolders with the tobacco that has been heated to an appropriate temperature, so as to generate smoke. During the inhalation, the tobacco of the cigarette can sufficiently smolder, and generate smoke for inhalation; the paper of the cigarette has a smaller area in contact with air, is less oxidized, and can maintain a relatively complete appearance, facilitating the removal of the cigarette from the heating tube after the inhalation of the cigarette.

Description

Heated non-burning tobacco fine hole suction device

Technical field

The utility model relates to the field of tobacco, in particular to a heating and non-burning tobacco fine hole smoking device.

Background technique

In the prior art, the heating non-combustion technique sucks the cigarette, and the cigarette paper is oxidized to a carbon state. After the end of the smoking, the cigarette paper is also carbonized into a pulverized state due to oxidation, so that the cigarette that has been sucked is not easily taken out. It is because the air is introduced into the entire interior of the cigarette, causing the oxygen-filled cigarette paper to be oxidized to carbon.

Summary of the invention

The technical problem to be solved by the utility model is to provide a heating non-combustion tobacco fine-hole smoking device, the air flows at the central axis position of the cigarette, and the smoldering reaction with the tobacco which has been heated to an appropriate temperature generates smoke, so it will not Carbonized external cigarette paper. .

The utility model is realized by the following technical solution: a heating non-combustion tobacco fine hole sucking device, comprising a heating pipe, wherein the heating pipe is provided with a tobacco heating cavity, wherein the inner diameter of the tobacco heating cavity of the heating pipe is larger than the insertion The outer diameter of the cigarette, one end of the heating tube is a smoke insertion port, and the other end is a smoke outlet, the diameter of the outlet is smaller than the diameter of the cigarette, the air is input from the position of the outlet, and the cigarette flows out from the mouth of the cigarette, the cigarette is from The smoke inlet is inserted into the heating tube, and the air flows at the central axis position of the cigarette, and smolders react with the tobacco heated to an appropriate temperature to generate smoke.

As a preferred technical solution, the cigarette comprises an outer cigarette paper and tobacco, and the tobacco is wrapped by a cigarette paper, and the outer diameter of the cigarette paper is slightly smaller than the inner diameter of the tobacco heating chamber.

As a preferred technical solution, one end of the cigarette is provided with a filter, and the filter protrudes On the outside of the heating tube, air enters from one end of the filter.

As a preferred technical solution, the bottom of the cigarette is in contact with the bottom surface of the heating chamber of the heating tube, and the central axis of the cigarette is directly opposite to the central axis of the outlet.

As a preferred technical solution, one or more spiral heating wires are disposed outside the heating tube, and the heating wire has an input electrode that is connected to an external power source.

The utility model has the beneficial effects that: the tobacco portion of the cigarette in the utility model can be fully smoldering, generating smoke for smoking, the cigarette paper is less in contact with the air, and less oxidation can maintain a relatively complete appearance, at the end of cigarette smoking. After that, it is convenient to take out the cigarette from the heating tube.

DRAWINGS

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings to be used in the embodiments or the description of the prior art will be briefly described below. Obviously, the drawings in the following description It is only some embodiments of the present invention, and those skilled in the art can obtain other drawings according to these drawings without any creative work.

Figure 1 is a schematic view of the overall structure of the present invention.

Detailed ways

All of the features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner other than mutually exclusive features and/or steps.

Any feature disclosed in the specification, including any additional claims, abstract and drawings, may be replaced by other equivalents or alternative features, unless otherwise stated. That is, unless specifically stated, each feature is only one example of a series of equivalent or similar features.

As shown in FIG. 1, a heating tube 6 is disposed. The heating tube 6 is provided with a tobacco heating chamber. The inner diameter of the tobacco heating chamber of the heating tube is larger than the outer diameter of the inserted cigarette, and one end of the heating tube 6 is the insertion port 3, and the other is One end For the outlet port 7, the diameter of the outlet 7 is smaller than the diameter of the cigarette, the air is input from the outlet 7 and flows out of the insertion port 3, and the cigarette is inserted into the heating tube from the insertion port, and the air is at the central axis position of the cigarette. It flows and reacts smoldering with tobacco that has been heated to a suitable temperature to produce smoke.

Wherein, the cigarette comprises an outer cigarette paper 4 and a tobacco 5, and the tobacco is wrapped by a cigarette paper, and the outer diameter of the cigarette paper 4 is slightly smaller than the inner diameter of the tobacco heating chamber. The cigarette can be placed just right, and the outer wall of the cigarette paper does not come into contact with the inner wall of the heating chamber, which can reduce contact and reduce the possibility of carbonization.

In this embodiment, one end of the cigarette is provided with a filter 2, and the filter 2 protrudes outside the heating tube, and air enters from one end of the filter 2. When the entire heating tube is heated, the internal tobacco is heated to generate smoke. By sucking the filter, we absorb the smoke generated by the heating of the cigarette, thereby achieving normal smoke smoking.

Wherein, the bottom of the cigarette is in contact with the bottom surface of the heating chamber of the heating tube, and the central axis of the cigarette is directly opposite the central axis of the outlet. The air outlet enters, directly aligns with the central axis of the cigarette, passes through the entire cigarette along the central axis and is discharged from the air inlet 1 into the human mouth, since most of the air passes through the central axis and is heated to the appropriate The temperature of the tobacco smoldering reaction produces smoke, but because the air is less in contact with the cigarette paper in the outer ring of the tobacco, less oxidation occurs, so that when the cigarette is used, the cigarette paper can maintain a relatively complete The shape is convenient for the cigarettes to be taken out from the heat pipe after the end of the smoking.

Wherein, the heating tube 6 is provided with one or more spiral heating wires, and the heating wire has an input electrode, which is connected with an external power source, and the heating tube structure can also adopt other heating structures, but as long as the cigarette can be heated.

The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, and any changes or substitutions that are not thought of by creative work should be covered within the scope of protection of the present invention. . Therefore, the scope of protection of the present invention should be determined by the scope of protection defined by the claims.
