Description

Technical Field

[0001] The present invention relates to the field of atomization technology, and in particular to a heating component and an atomization device. Background Art

[0002] Hookah, a tobacco product originating in the Middle East, traditionally involves inhaling a mixture of tobacco and other ingredients, such as honey, through a filter. The common method involves wrapping the paste in tinfoil, then punching a few holes in the foil for ventilation. The foil wrap, which temporarily wraps the paste, is then placed over a bowl on top of the filter. Charcoal is then placed on the foil wrap to heat the paste. However, heating the paste with charcoal can easily produce carbon monoxide, and the smell of ash can be noticeable during inhalation, making it difficult to clean up afterward.

[0003] Currently, water pipes that use electric heating to generate smoke have emerged. Compared to charcoal heating, electric heating does not produce carbon monoxide and ash, effectively improving the user experience. However, these water pipes often heat the tobacco from a single side, simulating traditional heating methods. This causes the tobacco closest to the heating surface to carbonize and burn, while the tobacco farther away from the heating surface is not fully heated and atomized, resulting in poor smoke quality and affecting the user experience. Summary of the Invention

[0004] Based on this, it is necessary to provide a heating component and an atomizing device, which can achieve the technical effect of uniformly heating the tobacco.

[0034] Figure 1 A schematic structural diagram of an atomization device in an embodiment of the present invention is shown.

[0035] See Figure 1 An embodiment of the present invention provides an atomization device 100, comprising a filter structure 40 and a heating assembly 20 detachably connected to the filter structure 40. The filter structure 40 comprises a filter structure body 41 and a smoke pipe 43 and a suction pipe 45 respectively connected to the filter structure body 41. The heating assembly 20 is detachably mounted on the smoke pipe 43 of the filter structure 40 and communicates with the filter structure body 41 through the smoke pipe 43. The heating assembly 20 is used to place and heat smoke-generating substrates such as tobacco shreds. The smoke generated by the heated tobacco shreds enters the filter structure body 41 from the heating assembly 20 through the smoke pipe 43. Liquids such as water in the filter structure 40 can filter the smoke, and the filtered smoke is output through the suction pipe 45 of the filter structure 40.

[0036] It should be noted that in the following embodiments, the filter structure 40 is a hookah. It is understood that the specific structure of the filter structure 40 does not belong to the main invention of this application and is not described here in detail. It can be configured as needed.

[0037] Combine Figure 2 As shown, Figure 2 A cross-sectional view of a main heating module in one embodiment of the present invention is shown.

[0038] In some embodiments, the heating assembly 20 includes a main heating module 21 and a preheating module 23. The main heating module 21 is detachably connected to the smoke pipe 43 of the filter structure 40. The main heating module 21 includes a heating chamber 2121 and an air outlet channel 2152 connecting the heating chamber 2121 and the smoke pipe 43. The preheating module 23 is detachably connected to the main heating module 21 and is located upstream of the external airflow flowing into the main heating module 21. The preheating module 23 has a preheating channel connecting the heating chamber 2121 and the external environment.

[0039] In this way, the tobacco can be placed in the heating chamber 2121 of the main heating module 21. The external space first enters the preheating channel and is preheated in the preheating channel, and then enters the main heating chamber 2121 to heat the tobacco. At the same time, the heating chamber 2121 can heat the tobacco therein, thereby forming all-round three-dimensional heating of the tobacco, making the tobacco heated more evenly, avoiding the situation where the heated tobacco is partially burnt while the rest of the tobacco is not heated. The smoke output speed is faster, the smoke is larger, and the taste consistency is better.

[0040] Figure 3 A cross-sectional view of the main heating module in another embodiment of the present invention is shown; Figure 4 A schematic diagram of an exploded view of a main heating module according to an embodiment of the present invention is shown.

[0041] Combine Figure 2 to Figure 4 As shown, the main heating module 21 includes a main shell 211, a heating cup 212, an upper cover unit 213, an intermediate connection unit 214, a vent pipe 215, a lower cover unit 216 and a filter structure joint 217.

[0042] The main housing 211 is a hollow tubular structure, comprising a first receiving chamber 2112, a second receiving chamber 2114, and a third receiving chamber 2116. The first receiving chamber 2112 and the second receiving chamber 2114 are coaxially arranged along the central axis of the main housing 211 and communicate with each other. The third receiving chamber 2116 circumferentially surrounds the second receiving chamber 2114. The end of the first receiving chamber 2112 facing away from the second receiving chamber 2114 communicates with the external environment, while the ends of the second receiving chamber 2114 and the third receiving chamber 2116 facing away from the first receiving chamber 2112 communicate with the external environment. The diameter of the first receiving chamber 2112 is greater than that of the second receiving chamber 2114. An annular limiting surface is defined between the first receiving chamber 2112 and the third receiving chamber 2116 to limit the position of the heating cup 212 and the vent tube 215.

[0043] The heating cup 212 is housed within the first receiving chamber 2112. The two ends of the heating cup 212 are restrained within the main housing 211 by an intermediate connecting unit 214 and an upper cover unit 213, respectively. The heating cup 212 is used to hold and heat tobacco. Specifically, the heating cup 212 has a cup-shaped structure, including a bottom wall and side walls extending from the edge of the bottom wall away from the second receiving chamber 2114. The side walls surround the bottom wall to form a heating chamber 2121 with an open end. The bottom wall is provided with a plurality of air outlets, which are spaced apart and each of which is connected to the heating chamber 2121.

[0044] In this way, the opening end of the heating chamber 2121 faces the first receiving chamber 2112 and away from the opening end of the second receiving chamber 2114. The user can put tobacco into the heating chamber 2121 from the opening end of the heating chamber 2121. The heating cup 212 can generate heat to heat the tobacco, and the smoke generated after the tobacco is heated can flow out through the air outlet.

[0045] The upper cover unit 213 includes an upper thermal insulator 2132 and an upper cover 2134. Both the upper thermal insulator 2132 and the upper cover 2134 are annular structures. The upper thermal insulator 2132 is located in the first receiving cavity 2112 and is mounted on the end of the heating cup side wall away from the bottom wall of the heating cup. The upper cover 2134 is mounted on the end of the main shell 211 away from the second receiving cavity 2114 and surrounds the upper thermal insulator 2132.

[0046] The intermediate connecting unit 214 includes a lower heat insulator 2141 and a connecting tube 2143. The lower heat insulator 2141 is annular and positioned on a limiting surface between the first receiving cavity 2112 and the second receiving cavity 2114. The connecting tube 2143 is a circular tube, one end of which is inserted into the main silicone pad. The end of the heating cup 212, which has the bottom wall of the heating cup, is inserted into the other end of the connecting tube 2143.

[0047] In this way, the heating cup 212 is limited in the main shell 211 by the upper cover unit 213 and the middle connecting unit 214, wherein the upper thermal insulation 2132 and the lower thermal insulation 2141 are formed of silicone material, which can play the role of support, sealing and heat insulation. While limiting the heating cup 212, it can effectively prevent the heat of the heating cup 212 from being transferred to the side wall of the main shell 211.

[0048] Furthermore, the upper cover unit 213 also includes two connectors 2136 for connecting to the preheating module 23. The two connectors 2136 are spaced apart in the radial direction of the upper thermal insulation member 2132, and each connector 2136 protrudes from the end surface of the upper thermal insulation member 2132 away from the second receiving cavity 2114. It will be understood that the number of connectors 2136 is not limited and can be provided as needed.

[0049] The vent 215 is a hollow tubular structure with two open ends. It forms an outlet passage 2152 for connecting the heating chamber 2121 with the filter structure 40. Smoke in the heating chamber 2121 flows into the filter structure 40 through the outlet passage 2152. Specifically, the vent 215 includes a first pipe forming a first outlet section and a second pipe forming a second outlet section. One end of the first pipe is inserted into the connecting pipe 2143, and the open end of the first pipe is aligned with the bottom wall of the heating cup, connecting the first outlet section with the heating chamber 2121. The other end of the first pipe is connected to one end of the second pipe, which then passes through the second receiving chamber 2114 and protrudes out of the main housing 211. Preferably, the sidewalls of the first pipe extend at an angle, and the inner diameter of the first outlet section gradually decreases from the end closest to the heating chamber 2121 to the end connected to the second outlet section. This allows the residue formed after the tobacco is burned to slide more smoothly, thereby preventing blockage in the outlet passage 2152.

[0050] One end of the filter structure connector 217 is connected to the end of the main housing 211 away from the first receiving chamber 2112 and is sleeved outside the ventilation tube 215 to communicate with the ventilation tube 215. The other end of the filter structure connector 217 is removably inserted into the smoke pipe 43 of the filter structure 40, thereby connecting the heating assembly 20 to the filter structure 40. Specifically, the filter structure connector 217 includes a first connecting portion and a second connecting portion. One end of the first connecting portion is inserted into one end of the third receiving chamber, and the second connecting portion is connected to one end of the first connecting portion and extends outside the main housing 211. The outer wall of the second connecting portion extends obliquely from the first connecting portion in a direction away from the heating cup 212. The outer diameter of the second connecting portion gradually decreases to mate with different types of filter structures 40.

[0051] Furthermore, the main heating module 21 also includes a control unit 2181 and a button 2183. The control unit 2181 is housed within the main housing 211 and electrically connected to an external power supply (AC power supply or DC adapter). The button 2183 is embedded in the side wall of the main housing 211. The heating cup 212 is electrically connected to the control unit 2181 via a wire. The control unit 2181 controls the heating cup 212 to heat the tobacco in the heating chamber 2121. The button 2183 is in communication with the control unit 2181, and the operator can adjust the smoke output by pressing the button 2183 to switch gears.

[0052] Figure 5 shows a cross-sectional view of a preheating module in one embodiment of the present invention; Figure 6 A cross-sectional view of a preheating module according to an embodiment of the present invention is shown from another angle; Figure 7 A schematic diagram of an exploded view of a preheating module in one embodiment of the present invention is shown.

[0053] Combine Figure 5 to Figure 7As shown, the preheating module 23 includes a top cover 231, a silicone ring 232, and a heating plate 233. The top cover 231 is a cylindrical structure with one end open. It includes a top wall and side walls extending in the same direction from the edge of the top wall. The side walls circumferentially surround the top wall to define a top cover receiving cavity. The top wall also has multiple air inlet holes to allow external air to enter the top cover receiving cavity.

[0054] The silicone ring 232 is annular and is housed within the open end of the top cover cavity. A connection hole is defined on the end face of the silicone ring 232, facing away from the top cover wall, that mates with the connector 2136. Thus, when the preheating module 23 is coupled to the main heating module 21, the connector 2136 is inserted into the connection hole.

[0055] The heating plate 233 has a circular sheet structure. The heating plate 233 is housed in the silicone ring 232. The edge of the heating plate 233 is limited to the inner wall of the silicone ring 232. The heating plate 233 has a ventilation gap that allows airflow to flow through. In this way, the top cover 231 and the silicone ring 232 jointly define a preheating channel. The heating plate 233 is located in the preheating channel to heat the air in the preheating channel. Specifically in one embodiment, the heating plate 233 is a circular ceramic heating plate 233. A plurality of through holes are provided on the ceramic heating plate 233 to form a ventilation gap. In some other embodiments, the heating plate 233 can also be a disc-shaped heating wire or a mesh heating plate.

[0056] In some embodiments, the preheating module 23 further includes at least one mesh heat storage sheet 234. The heat storage sheet 234 is located in the preheating channel and is spaced apart from the heating sheet 233 in the extension direction of the preheating channel. The heat storage sheet 234 is used to absorb the heat energy of the heating sheet 233 to heat the air passing through it, thereby further improving the preheating effect. Specifically, in one embodiment, the preheating module 23 includes two heat storage sheets 234, both of which are housed in the silicone ring 232 and are located on opposite sides of the heating sheet 233, and the edge of each heat storage sheet 234 is limited to the inner wall of the silicone ring 232. It can be understood that the number of heat storage sheets 234 is not limited to this and can be set as needed to meet different requirements.

[0057] Furthermore, to achieve electrical connection between the preheating module 23 and the control unit 2181, the main heating module 21 includes a first electrode 219 electrically connected to the control unit 2181, and the preheating module 23 includes a second electrode 235 electrically connected to the heating plate 233. When the preheating module 23 is coupled to the main heating module 21, the first electrode 219 is electrically connected to the second electrode 235, thereby supplying power to the heating plate 233.

[0058] Specifically, the upper insulation member 2132 of the primary heating module 21, which has a connector 2136 protruding from it, has two electrode mounting holes formed on one end thereof. The two electrode mounting holes are spaced apart in the radial direction of the upper insulation member 2132. Two first electrodes 219 are inserted into the two electrode mounting holes, respectively, with one end of each first electrode 219 flush with the end of the upper insulation member 2132. The two first electrodes 219 are electrically connected to the control unit 2181 via wires.

[0059] The two second electrodes 235 are retractable electrodes. One end of each second electrode 235 is inserted into the silicone ring 232, and the other end of each second electrode 235 protrudes from one end surface of the silicone ring 232. The two second electrodes 235 are electrically connected to the heating cup 212 via wires. When the preheating module 23 is separated from the main heating module 21, the second electrodes 235 are in their initial state. When the preheating module 23 is connected to the main heating module 21, the second electrodes 235 are in a compressed state and abut against the first electrode 219.

[0060] In this way, the electrical connection between the main heating module 21 and the preheating module 23 is achieved by utilizing the weight of the preheating module 23 itself. When it is necessary to add or replace tobacco, the preheating module 23 only needs to be removed directly from the main heating module 21 to expose the open end of the heating chamber 2121, which is highly convenient to use.

[0061] In some embodiments, the preheating module 23 further includes a counterweight 236, which is housed within the top cover 231 and located at one end of the top cover 231 where the top wall is located. The provision of the counterweight 236 increases the overall weight of the preheating module. The pressure of the counterweight 236 causes the second electrode 235 to abut against the first electrode 219, ensuring more reliable contact between the second electrode 235 and the first electrode 219.

[0062] The above-mentioned heating assembly 20 and atomizing device 100, through the heating module and the preheating module 23, jointly perform all-round three-dimensional heating of the tobacco, so that the tobacco is heated more evenly, avoiding the situation where some tobacco is burned while the rest of the tobacco is not heated, and improving the smoke output speed and smoke output, with a higher consistency of taste. Moreover, the preheating module 23 is electrically connected to the heating module through the weight of the preheating module 23 itself, and the preheating module 23 acts as a cavity cover of the heating chamber 2121, which improves the convenience of replacing tobacco. In addition, the air outlet channel 2152 is a sealed airflow channel, so the air outlet channel 2152 can be cleaned with liquids such as alcohol.

[0063] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
