Description

Technical Field

[0001] This patent relates to the field of novel tobacco product technology, specifically to a cleaning component for an aerosol generation device. Background Technology

[0002] With the rapid development of new tobacco technologies, heating devices, as a core component, are widely used in various tobacco and nicotine-based products. Heating devices typically include a heating chamber that uses different heating elements to heat the tobacco or e-liquid in the cartridge to its vaporization temperature, releasing a nicotine-containing aerosol for the user to inhale. During the heating process, volatile substances such as atomizing agents (glycerin, propylene glycol) in the tobacco vaporize upon heating, and some condense on the cooling section or the inner wall of the heating chamber, forming liquid residues. These condensates mainly include incompletely atomized glycerin and propylene glycol, tar and solid particles from the tobacco, and viscous substances formed from high-temperature decomposition products. These condensates easily adhere to the inner wall of the heating chamber, around the heating components, and in the flue. Long-term accumulation not only affects the heating efficiency and aerosol quality of the equipment but also causes "flavor transfer," resulting in a deterioration in the taste.

[0003] Currently, most mainstream heating appliances rely on external cleaning swabs, brushes, and alcohol cloths to wipe the inner walls. Due to the narrow inner walls of the heating chamber, it is difficult to completely remove condensation residue, and improper operation can easily damage the chamber.

[0004] To address the aforementioned problems, this invention provides a cleaning component that can be built into the heating appliance or installed separately, for cleaning condensed residues of soot on the inner wall of the heating chamber. Utility Model Content

[0005] To clean the condensed residue of e-liquid on the inner wall of the heating chamber, this patent provides the following technical solution:

[0006] First aspect: A cleaning component for an aerosol generating apparatus is provided. The aerosol generating apparatus includes a heating chamber for heating an aerosol-generating product. The heating chamber has a smooth cylindrical structure. The cleaning component includes a scraper and a collection groove. The scraper moves axially along the inner wall of the heating chamber to remove dirt. After the dirt is scraped off, it enters the collection groove for storage.

[0007] Furthermore, the heating chamber includes a cavity and a housing fitted outside the cavity, and the cleaning component is disposed inside the cavity. The cavity and the housing have sliding grooves that provide axial displacement of the cleaning component along the inner wall of the cavity.

[0008] Furthermore, the cleaning component also includes a connector and a sliding member for the storage groove and the scraping strip. The connector is disposed in the sliding groove, and by applying force to the sliding member, the cleaning component is driven to move axially along the inner wall of the heating chamber.

[0009] Furthermore, the maximum diameter of the scraping strip is greater than or equal to the diameter of the inner wall of the cavity; the maximum diameter of the storage groove is less than the diameter of the inner wall of the cavity.

[0010] Furthermore, the heating chamber also includes an elastic element. The diameter of the outer shell is larger than the diameter of the cavity. The elastic element is disposed between the outer shell and the cavity and provides a pushing force for the reset of the cleaning component after cleaning. The free travel height of the elastic element is 5-20mm, 20-35mm, or 35-50mm. The inner diameter of the elastic element is 4-12mm, 12-20mm, or 20-28mm. The elastic element is made of an elastic high-temperature resistant material, which is selected from stainless steel, piano wire, engineering plastics, and silicone.

[0011] Furthermore, the cleaning components are separated from the heating chamber, which is a cylindrical structure with a smooth inner wall.

[0012] Furthermore, the cleaning assembly also includes a handheld lever, which is fixedly connected to the scraper strip and pushes the scraper strip to move axially along the inner wall of the heating chamber.

[0013] Furthermore, the heating chamber is made of a high-temperature resistant material, which is selected from polyimide, polyetheretherketone, polyphenylene sulfide, aluminum alloy, or stainless steel.

[0014] Furthermore, the scraper strip and the storage groove are made of high-temperature resistant material, which is selected from polyimide, polyetheretherketone, high-temperature nylon, silicone or stainless steel.

[0015] Furthermore, the cleaning components are located within the aerosol generating device; or the cleaning components are located separately from the aerosol generating device.

[0016] This patent has the following beneficial effects:

[0017] 1. Compared with the prior art, the cleaning component provided by this patent can be directly built into the heating appliance without making significant changes to the original structure. It has good compatibility and integration adaptability and is suitable for various models of cigarette heating devices.

[0018] 2. It can form effective contact with the inner wall of the heating chamber, achieving efficient scraping of condensate residue, making the cleaning process more thorough, and effectively reducing the impact of condensate accumulation on airflow and heating efficiency;

[0019] 3. The residue scraped off during the cleaning process enters the specially designed collection tank through the guide structure, which prevents it from adhering or spreading again inside the cavity, helps to prevent secondary pollution, and improves the overall hygiene level.

[0020] 4. The cleaning component in this patent has a compact structure, requires minimal modification to the original heating appliance structure, and is easy to integrate; at the same time, it can thoroughly clean the inner wall of the cavity and has a condensate collection function, effectively preventing secondary pollution and improving hygiene.

[0021] 5. This component is easy to operate, provides a good user maintenance experience, and has a certain degree of interactivity and fun, enhancing the product's stickiness and added value.

Standard and extra-standard cigarettes, with a length of 75mm to 91mm and a circumference of 23mm to 25mm, are popular with many customers. Cigarette products of various sizes can also be manufactured with filters of different lengths. Generally, short filters are used for cigarette products with both short length and short circumference. Typically, filter tip lengths range from 15mm, used with "short" and "standard" cigarettes, to 30mm, used with "extra long" and "extra thin" cigarettes. The tipping paper in the longitudinal direction of the cigarette with a filter tip is, for example, 3mm to 10mm longer than the filter tip.

[0091] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0092] Example 1

[0093] Please refer to Figure 1 An aerosol generating apparatus 1000 with a cleaning component 1200 includes a cleaning component 1200 and a heating chamber 1100. The cleaning component 1200 is disposed inside the heating chamber 1100, which is used to heat the aerosol generating article. The cleaning component 1200 is used to remove the aerosol remaining in the heating chamber 1100 after heating the aerosol generating article.

[0094] For details, please refer to Figures 2-3 The heating chamber 1100 includes a cavity 1110, a shell 1130, an elastic element 1120, and a pressure plate 1140. The cavity 1110 and the shell 1130 are smooth cylindrical structures. The shell 1130 is fitted over the outside of the cavity 1110. The cavity inside the cavity 1110 is used to accommodate the cleaning component 1200 and support the cleaning component 1200 to move back and forth along the axial direction of the inner wall of the cavity 1110 to remove dirt.

[0095] As the main area where aerosols and condensates are deposited during the insertion and heating of aerosol-generated products, the heating chamber 1100 requires structural materials with excellent temperature resistance, mechanical strength and chemical stability to cope with the long-term corrosion of high-temperature environment and condensate residues.

[0096] Preferably, the heating chamber 1100 can be made of engineering plastics with a heat resistance temperature of not less than 150°C, such as polyimide (PI), polyether ether ketone (PEEK), polyphenylene sulfide (PPS), etc. Alternatively, it can be made of metal materials such as aluminum alloy and stainless steel, and its corrosion resistance and cleanliness can be improved by surface anodizing, electrophoretic coating or anti-stick coating.

[0097] In particular, to improve airflow stability and enhance cleaning efficiency, the inner wall of the cigarette holder cavity can be equipped with an anti-stick coating (such as a fluorine coating or a ceramic coating) to reduce the adhesion strength of condensate, reduce the frequency of cleaning, and improve the overall service life of the device.

[0098] Specifically, the cavity 1110 includes a first cavity wall 1111, a second cavity wall 1112, a first sliding groove 1113, a second sliding groove 1114, and a base 1115. The first cavity wall 1111 and the second cavity wall 1112 are arc-shaped, smooth, thin-shell structures. The first cavity wall 1111 and the second cavity wall 1112 are close to being fitted together to form a closed cylindrical structure and are symmetrically arranged on the base 1115. There are two gaps between the first cavity wall 1111 and the second cavity wall 1112, which are the first sliding groove 1113 and the second sliding groove 1114. The first sliding groove 1113 and the second sliding groove 1114 are arranged at 180° relative to each other and are used to support the cleaning component 1200 to slide back and forth inside the cavity 1110.

[0099] Specifically, the outer casing 1130 includes a side wall 1131, a third sliding groove 1132, and a fourth sliding groove 1133. The side wall 1131 is a cylindrical, hollow, and smooth thin-shell structure. The third sliding groove 1132 and the fourth sliding groove 1133 are disposed opposite to each other on the side wall 1131. The lengths of the first sliding groove 1113 and the second sliding groove 1114 are shorter than the lengths of the third sliding groove 1132 and the fourth sliding groove 1133. The third sliding groove 1132 and the fourth sliding groove 1133 extend from the top of the side wall 1131 downwards to the middle section of the side wall 1131. The third sliding groove 1132 and the fourth sliding groove 1133 also support the cleaning component 1200 to slide back and forth inside the cavity 1110, but at the same time limit the distance that the cleaning component 1200 can slide inside the cavity 1110.

[0100] Specifically, when the outer shell 1130 is fitted onto the outside of the cavity 1110, the bottom of the outer shell 1130 abuts against the base 1115. At this time, the openings of the first sliding groove 1113 and the third sliding groove 1132 are aligned with each other, and the openings of the second sliding groove 1114 and the fourth sliding groove 1133 are aligned with each other.

[0101] Specifically, since the diameter of the outer shell 1130 is larger than the diameter of the cavity 1110, after the outer shell 1130 is fitted onto the outside of the cavity 1110, there is an annular cavity between the outer shell 1130 and the cavity 1110. The height of the annular cavity is equal to that of the cavity 1110, and the annular cavity is used to accommodate the elastic element 1120.

[0102] Specifically, the pressure plate 1140 is located on top of the cleaning component 1200 and the heating chamber 1100, with a round hole in the middle. The round hole allows the product to be generated through aerosol and also serves as a dustproof function.

[0103] Please refer to Figures 4-6 The cleaning component 1200 includes a scraping strip 1210 and a storage groove 1220. The scraping strip 1210 and the storage groove 1220 are located on the top of the cavity 1110. When it is necessary to remove dirt, the scraping strip 1210 moves along the axial direction of the inner wall of the cavity 1110 to remove the dirt. After the dirt is scraped off, it enters the storage groove 1220 for storage.

[0104] Specifically, the scraper bar 1210 is trumpet-shaped, with the diameter near the top opening being larger than the diameter of the bottom opening. The maximum diameter of the scraper bar 1210 is greater than or equal to the diameter of the inner wall of the cavity 1110. The scraper bar 1210 includes a scraping edge 1211, which bends toward the inner wall and abuts against the inner wall. When the scraper bar 1210 moves downward, the scraping edge 1211 rubs along the axial direction of the inner wall of the cavity 1110, thereby scraping off the dirt on the inner wall of the cavity 1110.

[0105] Specifically, the components of the cleaning assembly 1200 can be integrally molded or multi-segmented to facilitate manufacturing or assembly. Among them, the scraper strip 1210 and the storage groove 1220 are key components that come into direct contact with the high-temperature environment inside the cavity 1110. Their materials should have good temperature resistance, with a heat resistance temperature of not less than 150°C, to ensure that they do not deform, soften, or deteriorate in performance during the cleaning process.

[0106] Preferably, the scraper strip 1210 and the collection groove 1220 can be made of high-temperature resistant engineering materials such as polyimide (PI), polyetheretherketone (PEEK), high-temperature nylon, and silicone. Alternatively, stainless steel or other metal materials with corresponding thermal stability can be selected to meet the requirements of different structural strengths and manufacturing costs. The selection of materials should comprehensively consider their compatibility with condensate, mechanical strength, processing performance, and long-term heat resistance stability to ensure the reliability and service life of the device.

[0107] Specifically, the storage groove 1220 is located at the opening near the bottom of the scraper strip 1210. The storage groove 1220 has an annular groove structure, and the maximum diameter of the storage groove 1220 is smaller than the diameter of the inner wall of the cavity 1110. When the scraper edge 1211 scrapes off the dirt on the inner wall of the cavity 1110, the dirt will fall into the storage groove 1220 or slowly flow into the storage groove 1220 from the guide wall 1212.

[0108] Specifically, the cleaning component 1200 also includes a first connector 1221, a first slider 1222, a second connector 1223, and a second slider 1224, wherein the first connector 1221 and the second connector 1223 are connecting rods, the thickness of the first connector 1221 is equal to the thickness of the first cavity wall 1111 and the second cavity wall 1112, and the thickness of the second connecting rod is equal to the thickness of the side wall 1131.

[0109] Specifically, the first sliding member 1222 and the second sliding member 1224 are ring-shaped retaining edges. The diameter of the second sliding member 1224 is larger than the diameter of the first sliding member 1222, serving as a support member for the elastic member 1120 to support the scraper strip 1210.

[0110] Specifically, the shapes of the first slider 1222 and the second slider 1224 can be the annular structure in this embodiment, or they can be a connecting rod, a buckle, a lock, or other suitable forms. This patent is not limited to these.

[0111] Specifically, the scraping strip 1210 is fixedly connected to the storage groove 1220, the storage groove 1220 is fixedly connected to the first connector 1221, the first connector 1221 is fixedly connected to the first sliding member 1222, the first sliding member 1222 is fixedly connected to the second connector 1223, and the second connector 1223 is fixedly connected to the second sliding member 1224.

[0112] For details, please refer to Figures 7-8The assembly relationship between the cleaning component 1200 and the heating chamber 1100 is as follows: the scraper strip 1210 and the receiving groove 1220 are disposed in the chamber 1110. The maximum diameter of the receiving groove 1220 is smaller than the diameter of the inner wall of the chamber 1110, and the maximum diameter of the scraper strip 1210 is greater than or equal to the diameter of the inner wall of the chamber 1110. Furthermore, the scraper edge 1211 and the inner wall of the chamber 1110 are in an equal or interference fit. The first connecting member 1221 is embedded in the first sliding groove 1113 and the second sliding groove 1114. The first sliding member 1222 precisely abuts against the outer wall of the chamber 1110 to prevent misalignment of the cleaning component 1200. The second connecting member 1223 is embedded in the third sliding groove 1132 and the fourth sliding groove 1133. At this time, the second sliding member... Part 1224 abuts against the outer wall of the outer shell 1130, thereby further fixing the cleaning component 1200 onto the heating chamber 1100. It is easy to understand that the inner ring side of the second sliding member 1224 abuts against the outer wall of the outer shell 1130, and the remaining part protrudes from the outer wall of the outer shell 1130. Below the first sliding member 1222 between the first connecting member 1221 and the second connecting member 1223 is an annular cavity, in which an elastic member 1120 is provided. It is easy to understand that the annular cavity is the extra space for the outer shell 1130 to fit onto the cavity 1110. It is easy to understand that when the cleaning component 1200 moves along the axial direction of the inner wall of the cavity 1110, the first sliding member 1222 easily generates a squeezing force with the elastic member in the annular cavity.

[0113] In use, by applying a downward pushing force to the second sliding member 1224, all components fixedly connected to the second sliding member 1224 move downward simultaneously. At this time, the elastic member 1120 is compressed, and the scraping ring 1210 scrapes the dirt on the inner wall of the cavity 1110 downward under the action of the pushing force. The scraped dirt is collected in the collection groove 1220. When the pushing force applied to the second sliding member 1224 stops, the spring that was originally compressed returns to its original position according to its elastic potential energy. During the return process, the cleaning component 1200 is pushed upward to the top of the cavity 1110. By repeatedly applying the pushing force to the second sliding member 1224, the cleaning component 1200 cleans the heating cavity 1100.

[0114] The design parameters of the elastic element 1120 should be optimized to match the mass, sliding friction, forming requirements, and drive type of the cleaning component 1200. To adapt to different structural dimensions and working requirements, the free travel height of the elastic element 1120 can be set between 5 and 50 mm, and the inner diameter of the spring can be set between 4 and 30 mm. It should be made of materials with good elastic recovery force and high-temperature stability, such as stainless steel spring steel (e.g., SUS304, SUS631), piano wire, or other high-performance alloy materials. Soft and elastic materials such as silicone can also be used. In practical applications, compression springs, disc springs, or other components with equivalent elastic functions can be flexibly selected according to the overall spatial layout of the device.

[0115] Example 2

[0116] This embodiment discloses an aerosol generating device 2000, which differs from Embodiment 1 in that it includes a cleaning component 2200 and a heating chamber 2100, with the cleaning component 2200 and the heating chamber 2100 being separately arranged. Please refer to... Figures 9-13 The heating chamber 2100 is a smooth cylindrical structure formed by the heating chamber wall 2110, which facilitates the movement of the cleaning component 2200 along the axial direction of the inner wall of the heating chamber 2100.

[0117] The cleaning component 2200 includes a scraping strip 2210, a storage groove 2220, and a hand handle 2230. The scraping strip 2210 has a fixedly connected hand handle 2230 at its center. By applying a pushing force to the hand handle 2230, the scraping edge 2211 is made to slide back and forth against the inner wall of the heating chamber 2100, so that dirt is scraped off from the inner wall of the heating chamber 2100 and enters the storage groove 2220 along the guide wall 2212.
