Description

Technical Field

[0001] The present invention relates to the technical field of electric heating smoking articles, and in particular to a cleaner and an aerosol generating system. Background Art

[0002] At present, the electric heating smoking devices on the market often encounter the problem of smoke-generating substances remaining on the surface of the heating body during use, which has a negative impact on the user experience. Take heated cigarettes as an example. As a new type of tobacco product, the main working principle of its mainstream products in the market is: during the consumer's smoking process, the special cigarettes are heated by electric heating of the smoking device, so that the atomizer, nicotine, and aroma components are atomized to meet the sensory and physiological needs of consumers. For example, a common heating element of a smoking device is a cylindrical needle-shaped heating core. This heating core is inserted into the tobacco material when used. After repeated use, thicker material adhesion and carbon deposition often occur on its surface, which seriously affects the heat transfer performance of the heating element, and then produces the following adverse effects: 1) It is difficult to insert and remove the cigarette, which is easy to cause the tobacco material to scatter and pollute, and the user experience is reduced; 2) It is easy to produce burnt gas, which reduces the sensory experience; 3) It is easy to cause local overheating, causing organic matter to undergo cracking reactions and produce harmful components.

[0003] In order to remove the adhesion and carbon deposits on the heating element, the following methods have been developed or adopted: using a relatively small brush, cotton swab, etc. to probe into the cavity to clean the heating core. Among them, there is a method of manually inserting the brush; there is also a method of implanting and fixing the brush in the device, such as patent document CN108354223A. However, since the adhesion and carbon deposits are very firm, the cleaning effect is often not good.

[0032] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Referring to Figure 1 - Figure 2 As shown, an embodiment of the present invention provides a cleaner for cleaning an electric heating smoking device, including: a handle 1 extending along the axial direction ( Figure 1 - Figure 2 shown as the X direction); a first scraper 2 connected to the handle 1 for cleaning the heating element of the electric heating smoking device.

[0034] In this embodiment, the handle 1 extending along the axial direction is provided to facilitate the user to hold and use the cleaner. The first scraper 2 is connected to the handle 1, which can be either directly connected or indirectly connected, and is used for cleaning the heating element of the electric heating smoking device. That is to say, when the cleaner is in use, the user holds the handle 1 to drive the first scraper 2 to contact the residues, carbon deposits, etc. on the surface of the heating element, and under the scraping force, separate them from the heating element, thus completing the cleaning. The shape and size of the first scraper 2 can be adaptively set according to the heating method, the shape of the heating element, etc., and this embodiment does not limit this.

[0035] Referring to Figure 1 As shown, in an embodiment, the electric heating smoking device (not shown in the figure) is an internal heating type, and the first scraper 2 is directly connected to the handle 1. Then, a through hole 21 is provided in the first scraper to facilitate the insertion of the heating element, and a concave portion is provided at the bottom of the handle 1 to facilitate accommodating the heating element (not shown in the figure) passing through the through hole 21, reducing the volume of the cleaner. Referring to Figure 2 As shown, in an embodiment, the electric heating smoking device (not shown in the figure) is an external heating type. The length L1 of the first scraper 2 in the radial direction ( Figure 2 shown as the Y direction) is basically the same as the inner diameter of the heating cavity of the smoking device (not shown in the figure), and the cutting edge 22 is arranged on the first scraper 2 along the circumferential direction ( Figure 2 shown as the Z direction). When in use, the user holds the handle 1 to drive the first scraper 2 to insert into the heating cavity (not shown in the figure). During the process of the first scraper 2 approaching the bottom of the heating cavity, it contacts the residues, carbon deposits, etc. on the inner wall of the heating cavity, and under the scraping force, separates them from the heating element, thus completing the cleaning.

[0036] In this embodiment, a scraper is used for cleaning instead of a brush, cotton swab, etc. Therefore, even if the adhesion and carbon deposition remaining on the electric heating smoking device are very firm, they can be separated from the heating element under the scraping force, with higher cleaning efficiency and better effect. And a handle is provided, making it more convenient to use. The cleaner disclosed in this embodiment does not consume the electric energy of the smoking device itself. Compared with the method of using the heating function of the heating element of the smoking device to generate high temperature for cleaning, it is more energy-saving and does not affect the continuous use ability of the device.

[0037] Adopting the above technical solution, the cleaner disclosed in this embodiment is convenient and efficient.

[0038] Refer to Figure 1 As shown, another embodiment of the present invention provides a cleaner. The first scraper 2 is provided with a through hole 21 along the axial direction ( Figure 1 shown as the X direction) for the heating element to be inserted. To ensure the physical safety performance of the product and prevent the heating element from breaking, the heating element of the inner core heating type smoking device is often designed and installed in a relatively narrow cavity. The cleaner disclosed in this embodiment can effectively and quickly remove the adhesion and carbon deposition on the heating element in a narrow space without damaging the structure of the smoking device, and is particularly suitable for cleaning the heating element of the inner heating type electric heating smoking device. The size and shape of the through hole 21 can be adaptively set according to the size and shape of the heating element, and this embodiment does not limit this. In one embodiment, the heating element is cylindrical and the through hole 21 is a round hole, that is, the bottom of the first scraper 2 is round hole-shaped. During use, the user holds the handle 1 and drives the round hole-shaped first scraper 2 into the heating cavity, moving from the top to the bottom of the heating element. During the movement, the heating element gradually inserts into the through hole 21, and the first scraper 2 contacts the materials, carbon deposition, etc. on the surface of the heating element along the axial direction. Under the scraping force, they are separated from the heating element, thus completing the cleaning. Preferably, the diameter of the through hole 21 is larger than the outer diameter of the heating element, and the difference does not exceed 0.1 mm, which can not only ensure that the heating element can smoothly insert into the through hole 21, but also ensure that the first scraper 2 can fully scrape off the materials, carbon deposition, etc., improve the reliability during use, will not damage the surface of the heating element, and can also avoid problems such as materials or carbon deposition leaking through due to too large a hole diameter and the cleaner shaking back and forth.

[0039] Refer to Figure 3 As shown, yet another embodiment of the present invention provides a cleaner, further including: a connecting portion 3. The connecting portion 3 extends along the axial direction ( Figure 3 shown as the X direction), and the first scraper 2 is connected to the handle 1 through the connecting portion 3. The connecting portion 3 is provided with a radial direction ( Figure 3A first brush 4 extending inward in the Y direction (shown) is provided, and the first brush 4 is used to clean the heating element. In this embodiment, the first scraper 2 is indirectly connected to the handle 1 through the connecting portion 3. A first brush 4 extending radially inward is provided on the connecting portion 3. The radial dimension of the first brush 4 can be set according to the outer diameter of the heating element, as long as the first brush 4 can contact the surface of the heating element when the cleaner is in use. When the cleaner disclosed in this embodiment is in use, when the heating element is gradually inserted into the through hole 21, the residual substances on the surface of the heating element are first separated from the heating element under the action of the first scraper 2. The carbon deposits and adhesives scattered due to being shoveled off can be swept into the gaps of the first brush 4, and the cleaning effect is better. And since the cleaner is provided with the handle 1, during the use process, when the first scraper 2 moves from the top of the heating element to the bottom of the heating element or reaches the bottom, the user can rotate the handle 1 so that the first brush 4 is in full contact with the surface of the heating element, and a more thorough cleaning can be conveniently achieved.

[0040] Preferably, referring to Figure 3 as shown, the number of the first brushes 4 is multiple, which are arranged axially in sequence. The length of the first brush 4 provided on the connecting portion 3 is greater than or equal to the length of the heating element. Therefore, when the first scraper 2 reaches the bottom of the heating element, rotating the handle 1 can achieve full cleaning of the entire surface of the heating element. Preferably, referring to Figure 3 as shown, the connecting portion 3 includes a first connecting sub-portion and a second connecting sub-portion symmetrically arranged along the through hole 21. Both the first connecting sub-portion and the second connecting sub-portion are provided with a plurality of first brushes 4 extending radially inward along their own axial directions ( Figure 3 shown in the X direction), and the structure is more stable and the cleaning efficiency is higher.

[0041] Referring to Figure 3 as shown, another embodiment of the present invention provides a cleaner. A second brush 5 extending radially outward is also provided on the connecting portion 3. The second brush 5 is used to clean the heating cavity of the electric smoking device. That is to say, for the cleaner disclosed in this embodiment, brushes are provided on the connecting portion 3 both radially inward and outward. Therefore, during the use process, both the cleaning of the heating element can be completed and the residual substances on the inner wall of the heating cavity can be removed. The size of the second brush 5 can be determined according to the position of the connecting portion 3 and the radial dimension of the heating cavity, as long as the second brush 5 can contact the inner wall of the heating cavity when the cleaner is in use. That is, the length of the second brush 5 in the radial direction is greater than or equal to the minimum distance from the connection point of the connecting portion 3 and the second brush 5 to the inner wall of the heating cavity.

[0042] Preferably, the number of the second brushes 5 is multiple. Referring to Figure 3As shown, they are arranged axially in sequence. The length of the second brush 5 provided on the connecting portion 3 is greater than or equal to the length of the heating chamber. Then, when the first scraper 2 reaches the bottom of the heating body, rotating the handle 1 can fully clean the inner wall of the heating chamber. Preferably, referring to Figure 3 As shown, the connecting portion 3 includes a first connecting sub-portion and a second connecting sub-portion symmetrically arranged along the through hole 21. Both the first connecting sub-portion and the second connecting sub-portion are provided with a plurality of second brushes 5 extending radially outward along their own axes. The structure is more stable and the cleaning efficiency is higher. Moreover, when the cleaner is inserted into the heating chamber of the smoking device, the second brush 5 can help the through hole 21 align with the heating body through its own supporting effect, thereby avoiding the situation where it cannot be inserted correctly. Preferably, the first brush 4 and the second brush 5 on each connecting sub-portion are symmetrically arranged.

[0043] Referring to Figure 4 - Figure 5 As shown, another embodiment of the present invention provides a cleaner, further including: a pedestal 6, the first scraper 2 is provided on the pedestal 6, and a second scraper 7 is further provided at one end of the pedestal 6 away from the handle 1. The angle between the blade plate of the second scraper 7 and the horizontal direction is α, 0° < α ≤ 90°. In this embodiment, the pedestal 6 and the first scraper 2 can be integrally formed, or can be formed separately and then fixed together by welding, bonding, etc. The second scraper 7 with a non-horizontal blade plate is provided at the bottom of the pedestal 6, so that an angle can be formed with the bottom of the heating chamber. During the use of the cleaner disclosed in this embodiment, when the first scraper 2 reaches the bottom of the heating chamber, the second scraper 7 can contact the bottom of the heating chamber. When the user holds the handle 1 and rotates, the second scraper 7 can contact the residual materials, carbon deposits, etc. at the bottom of the heating chamber and scrape them off. The length of the second scraper 7 in the radial direction ( Figure 5 shown in the Y direction) can be adaptively set according to the inner diameter of the heating chamber, as long as the second scraper 7 can be inserted into the heating chamber when the cleaner is used. This embodiment does not limit this.

[0044] Another embodiment of the present invention provides a cleaner. The cross-section of the second scraper 7 is crescent-shaped (referring to Figure 5 - Figure 6 shown) or triangular (referring to Figure 7 shown), which can respectively efficiently scrape the carbon deposits and adhesives on the surfaces of soft materials such as plastics or hard materials such as metals, playing a role in avoiding scratching the smoking device and enhancing the cleaning effect. In this embodiment, the cross-section is equivalent to the longitudinal section of the cleaner.

[0045] Referring to Figure 4 - Figure 5 As shown, another embodiment of the present invention provides a cleaner. A portion along the axis ( Figure 4The third brush 8 extends along the axial direction (shown in the X direction), and the length of the third brush 8 along the axial direction is greater than or equal to the length of the second scraper 7 along the axial direction. In this embodiment, by arranging the third brush 8 at the bottom of the base 6, when the second scraper 7 reaches the bottom of the heating chamber during the use of the cleaner, the third brush 8 contacts the bottom of the heating chamber, and the user turns the handle 1, so that the second scraper 7 can shovel up the carbon deposits and adhesions accumulated at the bottom of the heating chamber of the smoking device, and the third brush 8 can clean the shoveled residual materials or other residual materials at the bottom of the heating chamber, and sweep them into the gap of the third brush 8, so that the cleaning effect is better. Among them, the third brush 8 and the second scraper 7 can be set at any non-overlapping angle on the base 6, and this embodiment is not limited to this. In one embodiment, the cleaner includes a base 6 and a connecting portion 3, and the first scraper 2 is connected to the handle 2 through the base 6 and the connecting portion 3. Preferably, the first brush 4, the second brush 5 and the third brush 8 are soft metal wires or polymer materials with a certain rigidity, which are easier to brush off the adhered carbon deposits and have a better cleaning effect.

[0046] Reference Figure 4 - Figure 5 As shown, another embodiment of the present invention provides a cleaner, the number of the second scrapers 7 is two, the number of the third brushes 8 is two, and the second scrapers 7 and the third brushes 8 are arranged in a "cross" shape. That is to say, in this embodiment, the two second scrapers 7 are arranged along the same straight line, and the two third brushes 8 are arranged along the same straight line, and are perpendicular to each other. It can not only improve the cleaning efficiency, but also make the cleaner evenly stressed during use and turn more smoothly. Preferably, when the first scraper 2 is provided with a through hole 21 along the axial direction, the through hole 21 is located at the intersection of the radial extension lines of the third brush 8 and the second scraper 7, that is, the center of the base 6, and the structure is more stable.

[0047] Reference Figure 8As shown, in one embodiment, there is carbon deposit 91 on both the heating element 9 and the bottom of the heating chamber 10. The user holds the handle 2 and inserts the cleaner into the heating chamber 10. During the insertion process, the residual substances on the surface of the heating element 9, such as the carbon deposit 91, are first separated from the heating element 9 under the action of the first scraper 2, and then the scattered carbon deposit 91 and adherents due to being shoveled come into contact with the first brush 4 and are swept into the brush gap by the first brush 4. At the same time, the second brush 5 can sweep the residual substances on the side wall of the heating chamber 10 into the brush gap. When the cleaner is inserted to the bottom of the heating chamber 10 of the heated cigarette smoking device, by rotating the handle 1 in the clockwise rotation manner of general user habits, the carbon deposit and adherents accumulated at the bottom of the heating chamber 10 of the smoking device can be smoothly shoveled up by the horizontal second scraper 7 separately installed on both sides of the through hole 21 under the bottom pedestal 6. While the cleaner rotates, the first brush 4 and the second brush 5 installed axially, and the horizontal one-way third brush 8 on both sides of the through hole 21 under the bottom pedestal 6 work together, and the carbon deposit 91 and adherents scattered everywhere in the heating chamber 10 of the smoking device, including the heating element 9 and the bottom, can be fully swept into the brush gap. After repeatedly inserting - rotating - pulling out the cleaner several times, the heating element, the inner wall and the bottom of the heating chamber can be cleaned. Then, gently tap, blow or rinse the cleaner with water to clean the cleaner for the next use.
