[0042] To make the above objects, features, and advantages of the present application more obvious and understandable, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0043] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0044] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0045] In this application, unless otherwise clearly specified and defined, terms such as "installed", "connected", "linked", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature is at a lower horizontal level than the second feature.

[0047] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0048] As shown in the background art, in the traditional atomizing device, a porous heat exchange core is used near the bottom air inlet hole. During long-term use, aerosol backflow deposition easily causes the holes on the heat exchange core to be blocked, resulting in problems such as low heating efficiency, unsmooth air flow, and increased suction resistance. Moreover, for the outside space to enter the heat exchange core through the bottom air inlet hole, a special transition air duct design is required. During long-term use, there is a problem that the backflowed aerosol condenses inside the transition air duct and causes long-term deposition, resulting in peculiar smell and blocked air duct.

[0049] Based on this, please refer to Figures 1 to 2, the present application provides an atomizing device 100, which is used to heat and bake a solid atomizing medium 210 in an aerosol product 200 (see Figure 4 ), so that harmful substances (such as nicotine) and other substances in the solid atomizing medium 210 are precipitated to form an aerosol for inhalation.

[0050] Please also refer to Figures 2 to 4 , the atomizing device 100 includes a housing 10 and a heat exchange component 20. The heat exchange component 20 is arranged in the housing 10. One end of the housing 10 has a first jack 11. The aerosol product 200 is inserted into the heat exchange component 20 in the housing 10 through the first jack 11. The heat exchange component 20 heats and bakes the solid atomizing medium 210 of the aerosol product 200 in the housing 10, so that the solid atomizing medium 210 can form an aerosol for inhalation.

[0051] Among them, please also refer to Figures 5 to 8 , the heat exchange component 20 includes a heating tube 21 and a heat exchange core 22. The two ends of the heating tube 21 in the axial direction L have a first open end 211 and a second open end 212. The heat exchange core 22 is arranged in the first open end 211 and defines a heating cavity 23 for accommodating the aerosol product 200 with the heating tube 21. The first jack 11 communicates with the heating cavity 23 through the second open end 212. The aerosol product 200 extends into the heating cavity 23 along the axial direction L of the heating tube 21 through the first jack 11 and the second open end 212 until the bottom surface of the aerosol product 200 abuts against the heat exchange core 22. It can be understood that the bottom surface of the aerosol product 200 is arranged opposite to the top surface of the aerosol product 200 that enters the user's mouth outside the housing 10.

[0052] The second open end 212 forms an air inlet end 21a of the heating cavity 23, that is, the air flow and the aerosol product 200 in the heating cavity 23 both enter the heating tube 21 from the second open end 212. The heating tube 21 generates heat after being powered on. The outside air enters the heating cavity 23 through the air inlet end 21a, absorbs heat and the temperature rises to form a hot air flow. Furthermore, when the hot air flow blows towards the aerosol product 200, it heats and bakes the solid atomizing medium 210 to generate an aerosol.

[0053] Specifically, please refer to Figures 4 to 6 , a first air flow channel 213 is further defined in the heating tube 21. The first air flow channel 213 extends along the axial direction L of the heating tube 21 and communicates with the air inlet end 21a. The heat exchange core 22 includes a base 221 and a first support portion 222. The base 221 is connected to the heating tube 21. The first support portion 222 protrudes relative to the base 221 and defines a second air flow channel 223. The second air flow channel 223 communicates with the first air flow channel 213.

[0054] The base 221 and the heating tube 21 can be hermetically connected. Since one end of the heating tube 21 away from the base 221 forms an air inlet end 21a, the base 221 of the heat exchange core 22 does not undertake the function of air intake. That is, there is no need to punch holes in the heat exchange core 22 for the air flow and heat exchange between the heating cavity 23 and the aerosol article 200. In this way, the risk of blockage of the heat exchange core 22 is avoided, the suction effect is ensured, and it is convenient for the user to clean the heat exchange component 20 later.

[0055] The first air flow channel 213 can be formed inside the heating cavity 23. That is, the outer peripheral surface of the aerosol article 200 and the heating tube 21 are arranged at intervals to form the inner wall of the heating cavity 23. At this time, the first air flow channel 213 is defined between the outer peripheral surface of the aerosol article 200 and the inner wall of the heating cavity 23. When the air flow enters the first air flow channel 213, it is considered to enter the first air flow channel 213. The bottom surface of the aerosol article 200 abuts against the first support portion 222 of the heat exchange core 22 and is spaced from the base 221 in the axial direction L. Thus, the first support portion 222 and the base 221 define a second air flow channel 223. One end of the second air flow channel 223 is open and communicates with the bottom surface of the aerosol article 200. The air flow in the first air flow channel 213 can directly enter the second air flow channel 223 through the pores between adjacent first support portions 222. The air flow in the second air flow channel 223 enters the interior of the aerosol article 200 through the bottom surface of the aerosol article 200 to bake the solid atomization medium 210.

[0056] In other embodiments, the first air flow channel 213 can be formed inside the heating tube 21. For example, the first air flow channel 213 can be hollowed out along the axial direction L inside the heating tube 21, and an opening is made at one end to communicate with the second air flow channel 223, so as to introduce the air flow in the first air flow channel 213 into the heating cavity 23 and then into the second air flow channel 223.

[0057] The first support portion 222 can include one or more. The first support portion 222 protrudes into the heating cavity 23. The orthographic projection of each first support portion 222 facing the base 221 falls within the base 221 and the area is smaller than the orthographic projection surface on the base 221. On the one hand, the first support portion 222 is used to realize the abutment between the heat exchange core 22 and the aerosol article 200. On the other hand, it is used to form a second air flow channel 223 between the base 221 and the aerosol article 200 with the base 221, so as to heat the aerosol article 200 from the bottom of the aerosol article 200. Specifically, the first support portion 222 can be in any shape such as cylindrical, frustum-shaped, prismatic, etc., and the present application does not limit this here.

[0058] External air enters the interior of the heating tube 21 through the second opening 212, enters the first air flow channel 213 and flows along the axial direction L of the heating tube 21. Then, the air flow in the first air flow channel 213 enters the second air flow channel 223, and the second air flow channel 223 communicates with one end of the aerosol article 200. After the heating tube 21 generates heat, high-temperature air flows are generated in the first air flow channel 213 and the second air flow channel 223. When the preheating is completed, the negative pressure during the user's suction drives the high-temperature air flow in the second air flow channel 223 to enter the interior of the aerosol article 200 from one end of the aerosol article 200 located in the heating cavity 23, realizing the heating of the solid atomization medium 210 inside the aerosol article 200 to form an aerosol. The aerosol is driven by the air flow to enter the oral cavity through one side of the aerosol article 200 located outside the housing 10.

[0059] Thus, the heat exchange component 20 of the present application changes the traditional air intake mode of the heat exchange core 22, intakes air from one end in the axial direction L of the heating tube 21, and sets the base 221 of the heat exchange core 22 as a solid structure without openings, avoiding problems such as low heating efficiency and increased suction resistance caused by the blockage of the heat exchange core 22. Moreover, the air flow entering from the air intake end 21a can directly preheat the space outside the peripheral side wall and the air at the bottom of the aerosol article 200 through the first air flow channel 213 and the second air flow channel 223, improving the heating temperature and heating efficiency.

[0060] In some alternative embodiments of the present application, please refer to Figures 5 to 6 , the heating tube 21 forms a first surface 21b facing the inner wall of the heating cavity 23, the first surface 21b communicates with the first air flow channel 213, and the first air flow channel 213 is located on the side of the first surface 21b facing the heating cavity 23. In other words, the first air flow channel 213 is a part of the heating cavity 23.

[0061] Specifically, a second surface 220 is formed on the outer peripheral surface of the aerosol article 200, and the first surface 21b and the second surface 220 are spaced apart. At this time, the heating cavity 23 is divided into three parts. The first part is used for assembling the aerosol article 200, the second part between the first surface 21b and the second surface 220 is used for forming the first air flow channel 213, and the third part is located between the aerosol article 200 and the base 221, and the second air flow channel 223 is defined by the first support portion 222 and the base 221.

[0062] In some alternative embodiments, the first surface 21b may be an annular cylindrical surface, the second surface 220 may be an annular cylindrical surface, and the first surface 21b is sleeved around the outer periphery of the second surface 220 at intervals, defining a first air flow channel 213 that is annularly sleeved around the outer periphery of the aerosol article 200. That is, the entire outer peripheral surface of the heating tube 21 does not fit with the aerosol article 200. At this time, external air enters the first air flow channel 213 through the gap between the first surface 21b and the second surface 220 at the air inlet end 21a, uniformly surrounds the outer periphery of the aerosol article 200, diffuses along the axial direction L of the heating tube 21, and then diffuses radially into the second air flow channel 223 along the heating tube 21 to achieve uniform heating.

[0063] When the heating tube 21 generates heat, the first air flow channel 213 is heated to form a high-temperature air layer. The air layer and the second surface 220 form an annular heat exchange area, heating the aerosol article 200 to a certain temperature, avoiding partial condensation when pumping aerosol and the aerosol moves to the upper part in the aerosol article 200, thereby reducing the pumping resistance and the pumping difficulty at the initial stage.

[0064] Refer to Figure 6 , Figure 6 shows the radial dimension L of the first air flow channel 213 1 , that is, the interval dimension between the first surface 21b and the second surface 220 in the radial direction of the heating tube 21 Figure 6 At the same time, it shows the radial dimension L of the second air flow channel 223 2 , that is, the protruding dimension of the support member 71 in the axial direction L of the heating tube 21, L 1 is 0.2 mm (millimeter) - 0.4 mm, L 1 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm to ensure smooth air flow while improving the heating efficiency. L 2 is 0.7 mm - 1.5 mm, L 2 can be 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm to avoid the heat exchange core 22 being too close to and directly contacting the bottom surface of the aerosol article 200 while avoiding the heat exchange core 22 being too far from the bottom surface of the aerosol article 200 and improving the heating efficiency.

[0065] In some alternative embodiments of the present application, the heat exchange core 22 and the heating tube 21 are configured to be connected by a glaze co-firing process.

[0066] Specifically, refer to Figure 7 and Figure 8, a first assembly groove 2211 is provided on the outer peripheral surface of the base 221 of the heat exchange core 22. After the heat exchange core 22 and the heating tube 21 are prepared, the heat exchange core 22 is arranged in the second open end 212, and the first assembly groove 2211 is filled with glaze, and then the glaze is sintered and fixed to complete the integrated connection of the heat exchange core 22 and the heating tube 21, and the heat exchange core 22 and the heating tube 21 are sealed, and no later mechanical assembly is required, improving the heat transfer efficiency between the heat exchange core 22 and the heating tube 21. The first assembly groove 2211 can be a conventional structure such as a spiral groove provided on the outer periphery of the heat exchange core 22, and the present application does not limit this here.

[0067] In some alternative embodiments of the present application, the heating tube 21 includes two heating zones, and all the heating zones are arranged at intervals along the axial direction L of the heating tube 21. Each heating zone is provided with a heating element, and each heating element is configured to be independently turned on or off.

[0068] Specifically, a heating element is arranged on the outer periphery or embedded in the heating tube 21. The heating element can be an electric heating component such as a heating wire or a heating mesh. The heating tube 21 and the heat exchange core 22 are made of insulating materials with good heat conduction performance, such as aluminum alloy with insulation treatment.

[0069] The heating zones at different axial positions L are heated by the heating element. For example, the heating element close to the second air flow channel 223 can be turned on first to preheat the air flow in the second air flow channel 223. In other embodiments, the heating elements at different positions can be turned on according to the use requirements, so as to realize the heating of different heating zones.

[0070] In some alternative embodiments, refer to Figure 7 and Figure 8 , there are two heating zones, namely the main heating zone 214 and the auxiliary heating zone 216 respectively. The main heating zone 214 is arranged on the side of the heating tube 21 close to the heat exchange core 22. The main heating zone 214 is provided with a first heating element 215, and the auxiliary heating zone 216 is provided with a second heating element 217. The heat exchange assembly 20 has a first preheating state and a second preheating state that are carried out successively. In the first preheating state, the first heating element 215 is turned on and the second heating element 217 is turned off. In the second preheating state, the first heating element 215 is turned on and the second heating element 217 is turned on.

[0071] During actual operation, when the user activates the atomization device 100, first, the heating tube 21 preheats the airflows in the first airflow channel 213 and the second airflow channel 223. Specifically, the first heating element in the main heating area 214 rapidly heats up, quickly heating the air in the second airflow channel 223, that is, the air between the heat exchange core 22 and the aerosol product 200. After heating for a preset time, the second heating element 217 in the auxiliary heating area 216 starts to heat, heating the air in the first airflow channel 213, that is, the air in the first surface 21b and the second surface 220. After the preheating is completed, the negative pressure during suction drives the preheated high-temperature airflow in the heating chamber 23 into the interior of the aerosol product 200, realizing the heating and baking of the solid atomization medium 210 inside the aerosol product 200 to form an aerosol. The aerosol is driven by the airflow into the oral cavity to complete the suction process.

[0072] Moreover, the present application sets the first preheating state and the second preheating state that are carried out successively in time to heat the first airflow channel 213 and the second airflow channel 223, so that the airflows in the first airflow channel 213 and the second airflow channel 223 both have a relatively high temperature when mixing, improving the heating efficiency and avoiding the situation of direct mixing of cold and hot airflows.

[0073] As an example, both the first heating element 215 and the second heating element 217 can be one or more turns of heating wires, and the heating wires are wound along the axial direction L of the heating tube 21 to heat the large-area main heating area 214 and the auxiliary heating area 216. The leads of the heating wires can pass through the base 221 to achieve connection with an external power source.

[0074] In some alternative embodiments of the present application, refer to Figure 2 and Figure 9 and Figure 10 , the atomization device 100 includes a first cover 30 and a second cover 40. The first cover 30 and the second cover 40 are arranged at both axial ends of the heat exchange assembly 20 within the housing 10. Both the first cover 30 and the second cover 40 are connected to the housing 10. The first cover 30 is arranged at one end of the housing forming the first socket 11 and has a second socket 31, and the second socket 31 communicates with the heating chamber 23 through the second opening 212.

[0075] During actual assembly, the second cover 40 is assembled on one side of the housing 10, and then the heat exchange assembly 20 is assembled into the housing 10 to realize the connection between the base 221 and the second cover 40. Then, the first cover 30 is assembled on the housing 10. At this time, the second socket 31 formed by the first cover 30 is used for the aerosol product 200 and the outside air to enter.

[0076] Specifically, along the axial direction L of the heating tube 21, the aerosol product 200 is inserted into the heating cavity 23 through the second jack 31 and the second opening 212. Through the limitation of the first cover 30, the central axes of the aerosol product 200, the second jack 31, the second opening 212, and the heating tube 21 are collinear, and the outside air enters the first air flow channel 213 through the second jack 31 and the second opening 212.

[0077] Furthermore, the first cover 30 and the second cover 40 are hermetically connected to the housing 10, thereby forming a sealed space within the housing 10, achieving a fully sealed design, avoiding the condensation and accumulation of aerosol, and facilitating the cleaning of the atomization device 100.

[0078] In some alternative embodiments, referring to Figure 9 and Figure 10 , the atomization device 100 includes a first seal 50 and a second seal 60. The first seal 50 is hermetically connected between the first cover 30 and the inner wall of the housing 10, and the second seal 60 is hermetically connected between the second cover 40 and the inner wall of the housing 10.

[0079] Referring to Figure 2 , a second assembly groove 32 is provided on the outer periphery of the first cover 30, and a third assembly groove 41 is provided on the outer periphery of the second cover 40. The first seal 50 is disposed in the second assembly groove 32, and the second seal 60 is disposed in the third assembly groove 41, thereby realizing the upper and lower sealing of the axial direction L of the housing 10. The first seal 50 and the second seal 60 can be of a sealing ring structure, and the second assembly groove 32 and the third assembly groove 41 can be of a spiral groove structure. In some embodiments, the first cover 30 can achieve an interference fit with the housing 10 through the first seal 50, and the second cover 40 can achieve an interference fit with the housing 10 through the second seal 60.

[0080] It can be understood that at this time, the positions where the leads of the first heating element 215 and the second heating element 217 pass through the base 221 can be sealed with a sealing and heat-insulating colloid.

[0081] In some alternative embodiments of the present application, referring to Figure 2 and Figure 10, the atomization device 100 further includes an aerosol fixing member 70, the aerosol fixing member 70 has a plurality of second support portions 71, and a third insertion hole is defined inside all the second support portions 71. The second support portions 71 of the aerosol fixing member 70 are used to limit and fix the aerosol article 200. The aerosol article 200 can be inserted into the heat exchange component 20 at a position where its central axis coincides with the central axis of the heating tube 21 under the limitation of the plurality of second support portions 71. After the insertion of the aerosol article 200 is completed, the plurality of second support portions 71 fix the position of the aerosol article 200 to avoid the risk of the aerosol article 200 falling off due to the user's misoperation during the suction process.

[0082] Moreover, an air inlet hole 72 is formed between at least two adjacent second support portions 71, and external air communicates with the second open end 212 through the air inlet hole 72. In actual operation, after the aerosol article 200 is limited by the plurality of second support portions 71, the external air passes through the air inlet hole 72 between two adjacent second support portions 71, passes through the second insertion hole 31 and the second open end 212, and finally enters the first air flow channel 213.

[0083] In some alternative embodiments, the second support portion 71 can be a plurality of reinforcing rib structures arranged at circumferential intervals, and an air inlet hole 72 is formed between every two reinforcing rib structures to achieve air intake. The plurality of reinforcing ribs abut against the second surface 220 of the aerosol article 200, thereby fixing the aerosol article 200.

[0084] Based on the same concept, the present application also provides a heat exchange component 20 as in any one of the embodiments.

[0085] The above heat exchange component 20 and atomization device 100 change the traditional air intake mode of the heat exchange core 22. Air intake is carried out from one side of the first insertion hole 11 of the housing 10 (equivalent to the top of the entire atomization device 100) and enters the heating cavity 23 through one end of the axial direction L of the heating tube 21. In this way, the base 221 of the heat exchange core 22 can be set as a solid structure without opening holes, avoiding problems such as low heating efficiency and increased suction resistance caused by the blockage of the heat exchange core 22. Moreover, the air flow entering from the air inlet end 21a can directly preheat the space outside the peripheral side wall and the air at the bottom of the aerosol article 200 through the first air flow channel 213 and the second air flow channel 223, improving the heating temperature and heating efficiency.

[0086] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0087] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
