Description

Non-burning smoking implement with extractor

Technical field

The present disclosure relates to the field of smoking articles, and in particular to a non-combustion smoking article with an extractor.

Background technique

As the concern for physical health continues to rise, people are becoming aware of the dangers of burning smoking products to produce smoke to absorb the traditional smoking method, thus developing non-burning smoking articles.

Existing non-combustion smoking articles typically produce smoke from smoking articles by heating. The non-burning smoking article has a heating chamber for accommodating the smoking article, and the smoking device is heated to heat the smoking article by inserting the smoking article into the heating chamber of the non-combustion smoking article, so that the smoking article generates smoke for the user to smoke. . However, the smoking article is heated by the non-combustion smoking article of such a structure, and the aerosol-forming substrate of the smoking article after smoking is often easily adhered to the heater of the non-combustion smoking article or the heating chamber, and is difficult to be pulled out.

WO 2013/076098 discloses an aerosol generating device (i.e. the aforementioned non-combustion smoking article) having a heater insertable into an aerosol-forming substrate of a smoking article and for facilitating removal after use An extractor for smoking articles. The extractor has two positions, the first position being an operational position defined by the heater in contact with the aerosol-forming substrate, and the second position being an extraction position defined by the aerosol-forming substrate being separated from the heater. The extractor is used for extracting a smoking article received in the aerosol generating device, and is intended to separate the smoking article from the heating chamber of the non-combustion smoking article, and to facilitate the extraction of the aerosol-forming substrate of the smoking article after the starting smoke.

Although the extractor disclosed in WO 2013/076098 successfully maintains the integrity of the smoking article during removal, the Applicant has found that, in actual use, the aerosol-forming matrix has loose debris and other debris derived from the smoking article. It tends to fall outside the extractor, especially within the heating chamber, and accumulates in the area around the bottom of the heater of the aerosol generating device. This may adversely affect the heat generation efficiency of the heater and adversely affect the air flow path that causes air to pass through the aerosol-forming substrate. Due to the narrow space of the heating chamber, it is more difficult to efficiently clean the area around the bottom of the heater of the aerosol generating device.

On the other hand, the Applicant has found that, in actual use, the extractor extends mostly out of the heating chamber in the second position, leaving only a small portion remaining within the heating chamber. This causes the central axis of the entire extractor to easily deviate from the central axis of the heating chamber due to the deviation of the support from the center of gravity or other reasons. Over time, this deviation will become larger and larger, eventually leading to the inner wall of the heating chamber and the extractor. Misalignment, even damage to the heating chamber, extractor or heater. In addition, this deviation also causes the extractor to fail to properly align with the heater when it is reset, causing the extractor to fail to reset.

Some exemplary embodiments of the present disclosure are explained in detail below.

A non-combustion smoking article 100 with an extractor provided in accordance with a first embodiment of the present disclosure is schematically illustrated with reference to FIG. The non-combustion smoking article 100 includes a body 30, a heater 34, and an extractor 20. The body 30 includes a cavity wall 31a for forming a heating chamber 31. In this embodiment, the extractor 20 is in the form of a sleeve having a first end L1 and an open second end L2. An eyelet 21 through which the heater 34 passes is disposed in the first end portion L1. The first end L1 of the extractor 20 is closed except for the eyelet 21. The smoking article is inserted into the inside of the extractor 20 through the second end portion L2, and is inserted all the way to the first end portion L1. In Figure 1, extractor 20 is shown in an operational position, but does not show a smoking article. In this embodiment, the chamber wall 31a is in the form of a generally cylindrical tube having an inner diameter slightly larger than the outer diameter of the extractor 20 such that the extractor 20 is slidably received within the heating chamber. The second end L2 of the extractor 20 includes a flange 101. The flange 101 can be in the form of a protruding rim or a raised ring that abuts or is adjacent to the outer end of the cavity wall 31a when the extractor is in the operative position.

The extractor 20 also includes a guide pin 102 that projects out of the extractor 20 and projects into a linear guide (not shown) in the cavity wall 31a.

As shown in Figure 1, in the operative position, the extractor 20 is substantially completely received within the heating chamber 31, and the flange 101 at the second end L2 of the extractor 20 abuts the outer end of the chamber wall 31a or Adjacent, and the first end portion L1 of the extractor is adjacent to or abuts the support member 35 for mounting the heater 34. The heater 34 extends through the aperture 21 in the first end L1 of the extractor 20 and into the receiving cavity of the extractor 20.

Figure 2 shows the extractor 20 of Figure 1 in which the smoking article F is inserted into the non-combustion smoking article 100, particularly into the extractor of the non-combustion smoking article. As shown, the smoking article F has an elongated cylindrical shape and includes an aerosol-forming substrate F1 and a filter rod F2 which are successively arranged and coaxially aligned. The aerosol-forming substrate F1 and the filter rod F2 are wrapped with an outer paper wrap. This is merely a schematic representation of a smoking article that may include other components.

As shown in FIG. 2, in the operating position, the heater 34 can heat the aerosol-forming substrate F1 of the smoking article F to form an aerosol. The aerosol-forming substrate of the smoking article F received in the extractor 20 abuts against the first end portion L1 of the extractor 20. The first end portion L1 of the extractor 20 functions as an aerosol-forming substrate F1 for supporting the smoking article F. The heater 34 extends through the eyelet 21 in the first end L1 of the extractor 20 into the aerosol-forming substrate F1 of the smoking article F.

When the user draws on the smoking article, the heater 34 heats the aerosol to form the substrate F1 to form an aerosol. At the same time, air flows from the external environment along the gap between the outer wall of the extractor 20 and the chamber wall 31a of the heating chamber 31, and flows in and out through the gap between the support member 35 and the first end portion L1 of the extractor 20 and the orifice 21. Inside the device. Next, the aerosol formed by heating the aerosol-forming substrate F1 is transported through the filter rod F2 to the mouth of the user together with the air stream entering the extractor 20 for the user to smoke. Alternatively, an intake hole may also be formed in a portion of the chamber wall 31a close to the support member 35 and above the support member, the air being separated from the support member 35 and the first end portion L1 of the extractor 20 by the air inlet hole The gap between the two enters the extractor via the eyelet 21.

Figure 3 shows the extractor and smoking article of Figure 2 with the extractor 20 in the extraction position. When the smoking article F is completely depleted or when the user thinks that the smoking article is to be completely used up, the extractor 20 can be moved from the operating position shown in Fig. 2 to the extraction position shown in Fig. 3. As the extractor moves from the operating position toward the extraction position, the first end L1 of the extractor moves from a position adjacent or abutting the support member 35 in a direction away from the support member 35 while the smoking article F is in the extractor The support and the push are moved together with the direction away from the support member 35 (moving outward along the central axis of the heating chamber, i.e., the upward direction in Fig. 3). During this movement, the chamber wall 31a guides the movement of the extractor 20; the guide pin 102 moves along a linear guide (not shown) in the chamber wall 31a of the heating chamber, which ensures that the extractor does not rotate in the chamber wall. At the same time, the eyelet 21 moves away from the support member 35 along the heater 34, so that the heater 34 is gradually partially pulled out of the aerosol-forming substrate F1, so that the length of the heater remaining in the aerosol-forming substrate F1 is shortened or reduced. . As shown in FIG. 3, the length of the heater remaining in the aerosol-forming substrate F1 reaches a minimum when reaching the extraction position. At this time, the guide pin 102 is stopped against the end of the linear guide groove, thereby preventing the extractor from slipping out of the non-combustion smoking article; and the extractor and the smoking article are away from the support member 35, although the heater 34 is partially pulled out of the gas. The mist forms the matrix F1, but the heater 34 still extends through the aperture 21 and into the aerosol-forming substrate F1. That is, at the extraction position, a portion of the heater 34 remains in the aerosol-forming substrate F1 rather than being completely detached from the aerosol-forming substrate.

Thus, on the one hand, since the heater 34 has been moved relative to the aerosol-forming substrate F1 during the movement, the adhesion of the aerosol-forming substrate to the heater is broken, so that the user can easily take out the smoking article so that Discard or replace. Thus, although the heater is not completely separated from the aerosol-forming substrate at the extraction location as in the prior art, the extraction location can also serve to facilitate extraction or removal of the smoking article from the non-combustion smoking article. On the other hand, the shorter path of the extractor 20 from the operating position to the extraction position relative to the prior art can reduce the tendency of the aerosol-forming substrate to split, and is more advantageous to maintain the integrity of the aerosol-forming substrate during extraction. In the prior art, those skilled in the art generally believe that in order to extract the smoking article and prevent the adhesion, the extractor should be completely separated from the smoking article or the aerosol-forming substrate in the extraction position to better promote the smoking article. Extract or remove. However, the present disclosure overcomes this technical bias and the technical solution of the heater of the present disclosure that is not separated from the aerosol-forming substrate is more advantageous to maintain the integrity of the aerosol-forming substrate during extraction. Further, the present disclosure has achieved the following unexpected technical effects.

First, after testing, Applicants have found that the use of the non-combustion smoking articles of the present disclosure produces loose debris that falls in the extractor significantly less than in the prior art due to adhesion failure or pull-out of the heater. Some of the loose debris of the aerosol-forming substrate remains inside the aerosol-forming substrate because of a non-single detachment between the heater and the aerosol-forming substrate. This reduces the number of times the extractor is cleaned and extends the life cycle.

Secondly, during this movement the heater always extends through the aperture of the extractor, which at least partially forms a blockage or barrier to the aperture, so that the aerosol generated by the adhesion failure or pulling out of the heater forms the matrix Loose debris and other debris from the aerosol-generating article are left almost entirely inside the extractor, without causing it to fall within the heating chamber, and not accumulating in the area around the bottom of the heater, thereby advantageously improving The heating efficiency of the heater allows the air flow path to be clear and there is no need to clean the area around the bottom of the heater.

Third, since the path of the extractor 20 moving from the operating position to the extraction position is short, the portion of the extractor remaining in the heating chamber is longer than in the prior art. In this way, the central axis of the extractor does not easily deviate from the central axis of the heating chamber, maintaining the centering between the heating chamber and the extractor without causing damage to the heating chamber, extractor or heater over time.

Fourth, during the movement, the heater always extends through the aperture of the extractor, so that when the extractor is reset, there is no deviation or misalignment between the heater and the hole, and no need to make the heater and the hole again Precise operation greatly reduces the possibility of damage to the heater when the extractor is reset.

Further, in addition to the above-described functions or functions, the extractor 20 can function to insulate the chamber wall 31a from the heater 34. In order to further insulate, a heat insulating groove may be formed on the outer wall of the extractor 20, please refer to the second embodiment of the present disclosure.

As also shown in FIG. 3, at the extraction position, the aerosol-forming substrate F1 of the smoking article F is still received in the extractor 20 and still abuts the first end L1 of the extractor 20. However, the extractor is now only partially received in the cavity wall 31a.

As mentioned above, the removal and replacement of smoking articles from non-combustion smoking articles can be achieved in three stages. In the first phase, the user moves the extractor 20 from the operating position toward the extracted position. This can be done manually by the user pulling the extractor 20 partially out of the chamber wall 31a. For example, the user can grasp the flange 101 to perform a pull-out action, and the flange serves as an operation portion. Alternatively, this can be done automatically. In the second stage, the extractor 20 reaches the extraction position, and a portion of the heater 34 is pulled out of the aerosol-forming substrate F1, but a portion remains in the aerosol-forming substrate. In the third stage, the user removes the smoking article F that is remote from the support 35 but still in contact with a portion of the heater from the extractor 20 to discard or replace the new smoking article.

When returning the extractor 20 from the extraction position to the operating position, the user may first insert the smoking article F into the extractor and then push the flange 101 or push the hair toward the direction of the support member 35 (ie, toward the inside of the heating chamber) The smoking article F moves the extractor from the extraction position toward the operating position until it reaches a position adjacent or abutting the support member, that is, the operating position. Alternatively, the user can also insert the smoking article into the extractor after the extractor has reached the operating position.

In the first embodiment of the present disclosure, the guide pin 102 is disposed on the extractor 20, and the linear guide groove engaged therewith is disposed in the cavity wall 31a of the heating chamber. Alternatively, the guide pin and the linear guide can be interchanged, that is, the guide pin is disposed in the wall of the heating chamber and the linear guide is disposed on the extractor.

4 through 6 illustrate a non-combustion smoking article 200 with an extractor in accordance with a second embodiment of the present disclosure. The non-combustion smoking article 200 includes a rotating outer casing 10, an extractor 20, and a body 30 having a heating chamber 31. A heater 34 is disposed in the heating chamber 31. The extractor 20 is mounted in the heating chamber 31 of the body 30, and a receiving chamber for receiving the smoking article is opened inside the extractor. The extractor has opposing first end portions L1 and second end portions L2, the first end portion L1 being generally closed and the second end portion L2 being open for the smoking article to enter the receiving cavity. A spiral guide groove 22 is provided on the outer wall of the second end portion L2. The rotating outer casing 10 is hollow, one end of which is sleeved on the body 30, and the other end is provided with a snap member 11 which is slidably engaged with the spiral guide groove 22. In an example, the clip 11 is a separately formed or integrally formed raised structure, such as a pin. The cavity wall 31a of the heating chamber 31 is provided with a linear guide 32 in the direction from the bottom thereof to the cavity thereof; correspondingly, the extractor is provided with a linear guide groove 23 which is slidably engaged with the linear guide 32 on the outer wall from the first end portion L1. For linearly moving the extractor in the heating chamber without rotating when the extractor 20 is screwed in/out of the heating chamber 31.

In an embodiment of the present disclosure, the end of the rotating housing 10 that is sleeved onto the body 30 can be rotated relative to the body 30, and when the rotating housing 10 is rotated about the body 30 in the counterclockwise direction as shown in the figure, the card The connector 11 and its corresponding spiral guide groove 22 cooperate with each other to partially rotate the extractor 20 out of the heating chamber 31, so that the extractor 20 slides in the direction of the bottom of the heating chamber 31 to its cavity, so that the extractor 20 The smoking article F in the receiving chamber moves together with the extractor toward the cavity of the heating chamber 31, and the heater 34 is partially pulled to form the aerosol-forming substrate F1 of the smoking article F, but still partially remains with the aerosol-forming substrate. F1 is in contact (as shown in Figure 6). When the rotating housing 10 is rotated clockwise about the body 30 in the BA shown in the drawing, the latching member 11 and its corresponding helical guide groove 22 are cooperatively slid so that the extractor 20 is along the cavity of the heating chamber 31 to The direction of the bottom slides such that the extractor 20 is substantially fully screwed into the heating chamber 31 (as shown in Figure 5).

The related descriptions of the components in the embodiment that are the same as or similar to the first embodiment are not described herein again. For details, refer to the first embodiment.

The spiral guide groove 22 and the linear guide groove 23 are disposed offset from each other and do not affect the rotation of the rotary housing 10.

The number of the clips 11 may be one or plural. The spiral guide groove 22 is identical in number to the clip member 11. The linear guides 32 may be one or plural. The linear guide groove 23 and the linear guide 32 are identical in number.

Preferably, as shown in FIG. 4, the number of the spiral guide grooves 22 is two, and the number of the linear guide rails 32 is two. In order to facilitate the rotation of the rotating outer casing 10 to drive the extractor 20 to move outward, the two spiral guide grooves 22 are symmetrically disposed. For example, the outer wall of the extractor 20 is provided with two spiral guide grooves 22 which are symmetrically arranged with respect to the central axis of the extractor.

In the second embodiment of the present disclosure, the illustrated snap member 11 is disposed on the inner wall of the rotary housing 10, and the spiral guide groove 22 mated thereto is disposed on the outer wall of the extractor 20. Alternatively, the clip and the helical guide can be interchanged, that is, the clip is disposed on the outer wall of the extractor and the spiral guide is disposed on the inner wall of the rotary housing. Similarly, the position of the linear guide and the linear guide is the same.

In the above embodiment, in order to facilitate the rotation of the rotating casing 10 and to prevent the rotating casing 10 from coming off the extractor 20 and the body 30, a retaining projection is provided on the inner wall of the end of the rotating casing 10 remote from the engaging member 11 (not show). A retaining groove 33 extending in the circumferential direction is correspondingly provided on the outer wall of the body 30 to prevent the rotating outer casing 10 from being displaced away from the body 30. The anti-off projection is slidably engaged with the anti-drop groove 33.

Further, preferably, in order to reduce the heat transfer of the heater 34 to the rotary casing 10 and prevent the non-combustion smoking article 200 from being burnt, the heat insulating groove 25 is provided on the outer wall of the first end portion L1 of the extractor 20. By burying a portion of the outer wall of the first end portion L1, leaving a thin wall, the groove formed is a heat insulating groove 25. Since a heat insulating space is formed between the heat insulating groove 25 and the cavity wall 31a of the heating chamber 31, heat radiated by the heater 34 during the heating process passes through the heat insulating groove 25, and is blocked by the air in the heat insulating space. Or cooling, thereby reducing the transfer of heat from the heater 34 to the rotating housing 10 or body 30. In some embodiments, a thermally insulating material can be placed within the insulated tank.

Referring first to Figure 7, the non-combustion smoking article 300 includes an extractor 20, a heating assembly 301, a body 30, and a pusher 302. In this embodiment, the pusher 302 is in the form of a push button. A control board 61 and a battery 62 are disposed in the body 30. The heating assembly 301 includes a heater 34. The heater 34 and the battery 62 are both connected to the control board 61.

An extractor 20 is disposed above the body 30 for placing the smoking article F and facilitating extraction of the smoking article. The bottom of the extractor 20 is provided with an eyelet (not labeled) for the heater 34 to pass through. The pusher 302 is engaged or coupled to the extractor 20. Referring to Figure 7, when the extractor 20 is moved to the operating position with the pusher 302, the heater 34 is substantially completely inserted into the extractor 20, at which point the smoking article F can be placed in the extractor 20 for heating to create an aerosol. For users to take. Referring to Fig. 8, when the extractor 20 moves to the extraction position with the pusher 302, the heater 34 is gradually pulled partially to the aerosol-forming substrate F1 of the smoking article F, but there is still a portion of the aerosol formed in the smoking article. In the matrix. At this time, the adhesion of the heater to the aerosol-forming substrate has been broken, and the user can easily take out the smoking article for disposal or replacement.

In the third embodiment of the present disclosure, the heating assembly 301 further includes a support member 35 that is fixed above the body 30 and the heater 34 is fixedly mounted by the support member 35. The non-combustion smoking article 300 also includes a cover 303. The support member 35 is lockedly coupled to the cover 303 by a latching recess 351. The advantage of this arrangement is that the cover 303 can be easily removed.

In some examples, the cover 303 is cylindrical. The top of the cylindrical cover 303 is provided with an opening for the smoking and dispensing of the smoking article F. The bottom end of the cylindrical cover 303 is provided with a projection 352 that is latchedly coupled to the latch recess 351. The top end of the cover 303 is also provided with a stop for preventing the extractor from coming off the non-combustion smoking article. In the illustrated embodiment, the stop is a stop or flange that projects inwardly.

The pusher 302 includes a first branching portion 302a and a second branching portion 302b. The first branching portion 302a is coupled or connected to the extractor 20. The second branching portion 302b is located outside the first branching portion, and the first branching portion constitutes a groove in which the side wall of the cover 303 slides. In this way, the pusher 302 can be engaged with the cover 303 during the sliding process to support each other to form a relatively stable sliding path.

In some examples, the extractor 20 is detachably coupled to the pusher 302. Further, the extractor 20 can be coupled to the pusher 302 by a latch or magnetic attraction. In this way, the extractor 20 can be relatively easily removed from the pusher 302. The extractor 20 is moved to the extraction or operational position by pushing the pusher 302 up and down (in the illustrated embodiment, specifically pushing the second bifurcation 302b).

Of course, as shown in FIGS. 7 and 8, the two can also be simply connected in such a manner that the second end of the extractor 20 is provided with an outward flange, and the top end of the first branch of the pusher 302 is disposed. There is an inwardly directed flange, the two flanges are in contact such that when the pusher 302 is pushed up, the flanges abut each other and move together, thereby causing the extractor to reach the extraction position. While returning from the extraction position to the operating position, the user simply inserts the smoking article into the extractor and relies on the downward thrust of the smoking article to reset the extractor and pusher together. Alternatively, the pusher 302 is pushed down first, the extractor 20 loses support and descends to the operating position with the pusher under the force of gravity, and then the smoking article is inserted into the extractor. It is also possible to first push the smoking article into the extractor and then push the pusher 302 downward.

In some examples, the pusher 302 can be associated with the control panel 61 for transmitting a first control signal to the control panel 61 as the pusher 302 moves toward the extraction position; to the control when the pusher 302 is moved to the operational position The board 61 transmits a second control signal. The control board 61 controls the heater 34 to stop generating heat upon receiving the first control signal, and controls the heater 34 to start generating heat upon receiving the second control signal.

In particular, in a specific implementation, a switch can be made at the pusher 302 for turning the circuit on or off; when the pusher 302 is moved to the operating position, the circuit can be turned on to output a control panel 61 When the control board 61 receives the high level signal, the heater 34 starts to generate heat; when the pusher 302 moves toward the extraction position, the circuit can be turned off, and a low level is output to the control board 61, and the control board 61 When the low level signal is received, the heater 34 is controlled to stop heating. This achieves automatic control of the heater 34 during the movement of the pusher 302.

In some examples, the body is also provided with electrical contacts 63 on its sidewalls. The electrical contact 63 is connected to the control board 61. When the pusher 302 is moved to the operating position, the electrical contact 63 is blocked; when the pusher 302 is moved to the extraction position, the electrical contact 63 is exposed. Thus, when the non-combustion smoking article is used (the pusher 302 is moved to the operating position), the electrical contact 63 is automatically obscured to avoid contamination or damage to the electrical contacts during use. When the non-combustion smoking article is not being used, such as charging, the pusher 302 can be moved to the extraction position to expose the electrical contacts 63, facilitating the completion of corresponding connections such as charging, communication, and the like.
