Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomization device and an aerosol generation system. Background Technology

[0002] Aerosols are colloidal dispersion systems formed by solid or liquid particles dispersed and suspended in a gaseous medium. Aerosols can be absorbed by the human body through the respiratory system, providing users with a novel alternative absorption method. Atomizing devices are devices that generate aerosols from stored atomizing media through heating or ultrasound. Atomizing media include liquid, gel, paste, or solid aerosol-generating matrices. Atomizing these media delivers inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] Heated non-combustible atomizing devices, as a type of atomizing device, are used to heat and atomize columnar aerosol products. The aerosol products can be inserted into the atomizing chamber through the nozzle of the atomizing device. However, due to structural defects, existing heated non-combustible devices are prone to drawing in cold air from the outside through the air outlet, resulting in condensation in the gas channel near the air inlet. The condensate accumulates in the gas channel and is difficult to clean, thus posing a hygiene hazard to the atomizing device. Utility Model Content

[0004] Therefore, it is necessary to provide an atomizing device and an aerosol generation system to address the problem of condensate accumulation in atomizing devices.

[0005] An atomizing device, comprising:

[0006] A housing having a receiving cavity, one end of the housing having an insertion port communicating with the receiving cavity, and the other end of the housing having an air outlet channel communicating with the receiving cavity; and

[0007] A heating component is disposed within the accommodating cavity and connected between the insertion port and the air outlet channel. The heating component forms an atomizing channel that connects the insertion port and the air outlet channel. The atomizing channel is used to accommodate the aerosol-generated product.

[0008] In one embodiment, the heating assembly includes:

[0009] Heating element;

[0010] A first bracket is connected between one end of the heating tube and the insertion port; and

[0011] The second bracket is connected between the other end of the heating tube and the air outlet channel;

[0012] The first support, the heating tube, and the second support are interconnected to jointly form the atomization channel.

[0013] In one embodiment, the second support has a first abutting surface for abutting the aerosol-generating article.

[0014] In one embodiment, the second bracket includes a second bracket top wall and a second bracket side wall extending in the same direction from the edge of the second bracket top wall. The end of the second bracket away from the second bracket top wall is connected to the heating tube, and the end of the second bracket with the second bracket top wall is connected to the air outlet channel.

[0015] The second bracket has a connecting opening on its top wall, which connects the atomizing channel and the air outlet channel. The first abutting surface is formed on the side surface of the second bracket's top wall facing the heating tube and surrounds the connecting opening circumferentially.

[0016] In one embodiment, a connecting groove is provided on the side of the top wall of the bracket facing the heating tube.

[0017] In one embodiment, the air outlet channel has a second abutment surface for abutting the aerosol-generating article.

[0018] In one embodiment, the air outlet channel includes a first air outlet section and a second air outlet section that are interconnected. The second air outlet section is located on the side of the first air outlet section away from the heating tube. The inner diameter of the first air outlet section is larger than the inner diameter of the second air outlet section. One end of the first air outlet section connected to the second air outlet section forms the second abutment surface.

[0019] In one embodiment, the heating assembly further includes a heat insulation layer that covers the outer wall of the heating tube.

[0020] In one embodiment, the atomizing device further includes a power supply component disposed within the accommodating cavity and located on one side of the heating component, the power supply component being electrically connected to the heating component to provide power to the heating component.

[0021] An aerosol generation system includes the aforementioned atomizing device. The aerosol generation system further includes an aerosol generation article, one end of which is inserted into the atomizing channel through the insertion port, and the other end of which protrudes outside the insertion port.

[0022] In the aforementioned atomizing device, one end of the aerosol generating product can be inserted into the atomizing channel through an insertion port. Both the functional section and the medium section of the aerosol generating product are located within the atomizing channel, and the functional section is connected to the outlet channel. One end of the plug section is located within the atomizing channel, while the other end is located outside the insertion port. The heating component heats and atomizes the aerosol generating product to produce aerosol. The aerosol generated by the aerosol generating product flows out through the outlet channel for user consumption.

[0023] Since the aerosol-generated product can completely fill the atomization channel and the insertion port, it can prevent the formation of condensate due to external air entering the atomization channel through the insertion port, thereby preventing the condensate from depositing in the atomization channel and causing hygiene hazards.

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] See Figure 1 and Figure 2 The embodiments of this application provide an aerosol generation system 1000, including an atomizing device 100 and an aerosol generation article 200 inserted into the atomizing device 100. The atomizing device 100 is used to heat the aerosol generation article 200 to generate aerosol for user use.

[0041] In some embodiments, the aerosol generating article 200 has a cylindrical structure, including a plug section 210, a medium section 230, and a functional section 250 arranged sequentially along the axial direction. The plug section 210 includes a porous adsorbent material such as cotton, used to adsorb aerosols that have not flowed out of the aerosol generating article 200, effectively preventing the formation of condensate and contamination of the atomizing device 100. The medium section 230 includes an aerosol generating matrix for generating aerosols. Specifically, in some embodiments, the aerosol generating matrix may be formed from plant materials, such as plant roots, stems, leaves, flowers, buds, and seeds. The functional section 250 includes a filter material such as cotton, used to filter the aerosols generated by the medium section 230. It is understood that the specific structure of the aerosol generating article 200 is not limited to this and can be configured as needed.

[0042] Please see Figure 2 and Figure 3 The atomizing device 100 includes a housing 120 and a heating assembly 140. The housing 120 has a receiving cavity 120a, one end of the housing 120 has an insertion port 123a communicating with the receiving cavity 120a, and the other end of the housing 120 has an outlet channel 1212 communicating with the receiving cavity 120a. The heating assembly 140 is disposed in the receiving cavity 120a and connected between the insertion port 123a and the outlet channel 1212. The heating assembly 140 forms an atomizing channel 140a communicating with the insertion port 123a and the outlet channel 1212. The atomizing channel 140a is used to accommodate the aerosol generating product 200, and the heating assembly 140 is used to heat the aerosol generating product 200 in the atomizing channel 140a.

[0043] Thus, one end of the aerosol generating article 200 can be inserted into the atomizing channel 140a through the insertion port 123a, while the other end protrudes outside the insertion port 123a. Specifically, the functional section 250 and the medium section 230 of the aerosol generating article 200 are both located within the atomizing channel 140a, and the functional section 250 is connected to the outlet channel 1212. One end of the plug section 210 is located within the atomizing channel 140a, while the other end is located outside the insertion port 123a. The heating component 140 can heat and atomize the aerosol generating article 200 to generate aerosol, which flows out through the outlet channel 1212 for the user to use.

[0044] Since the aerosol generating product 200 can completely fill the atomization channel 140a and the insertion port 123a, it can prevent the formation of condensate due to external air entering the atomization channel 140a through the insertion port 123a, thereby preventing the condensate from depositing in the atomization channel 140a and causing hygiene hazards.

[0045] In the prior art, one end of the atomizing channel is not filled with the aerosol generating product. After the suction ends, a negative pressure exists within the atomizing channel, drawing in cold air from outside the atomizing channel. This cold air enters the unfilled portion of the atomizing channel, causing the aerosol remaining in the atomizing channel to condense and remain there. However, in this application, since the aerosol generating product 200 completely fills the atomizing channel 140a, even if external air enters the atomizing channel 140a, the condensate formed will adhere to the aerosol generating product 200 and be removed when the aerosol generating product 200 is replaced, without remaining in the atomizing channel 140a.

[0046] Please continue reading. Figure 2 and Figure 3 The outer casing 120 is generally cubic in shape. In the following embodiments, the height direction of the outer casing 120 is defined as the first direction (i.e., Figure 2 (in the Z direction). The outer casing 120 includes a first casing 121 and a second casing 123, which are mated to each other along a first direction.

[0047] The first housing 121 has a hollow structure, including a top wall and a side wall extending from the edge of the top wall in a first direction. The side wall surrounds the top wall circumferentially to form a cavity 120a with one end open. One side of the top wall protrudes away from the bottom wall and forms an exhaust channel 1212 extending in the first direction. The cross-section of the exhaust channel 1212 perpendicular to the first direction is circular.

[0048] The second housing 123 is assembled at the end of the first housing 121 away from the top wall of the housing. The second housing 123 has an insertion port 123a extending in the first direction on one side, and the air outlet channel 1212 and the insertion port 123a are coaxially arranged in the first direction.

[0049] The heating component 140 is generally a hollow tubular structure. The central axis of the heating component 140 extends along a first direction and includes a heating tube 141, a first support 143 and a second support 145 that are connected to each other.

[0050] The heating tube 141 is a hollow cylindrical tube with openings at both ends, and its central axis extends along a first direction. The tube wall of the heating tube 141 is provided with a heating element, which generates heat under the action of electrical energy to heat the aerosol-generated product 200. Specifically, in some embodiments, the heating element may be formed of a metal heating wire or a metal heating mesh.

[0051] The first support 143 is a hollow cylindrical structure with openings at both ends, and the central axis of the first support 143 extends along the first direction. One end of the first support 143 is sleeved on the outside of the end of the heating tube 141 near the insertion port 123a, and the other end of the first support 143 is inserted into the end of the insertion port 123a near the heating tube 141 along the first direction.

[0052] The second support 145 is a hollow cylindrical structure with openings at both ends, and the central axis of the second support 145 extends along the first direction. One end of the second support 145 is sleeved on the end of the heating tube 141 away from the first support 143, and the other end of the second support 145 is inserted into the end of the air outlet channel 1212 near the heating tube 141.

[0053] Thus, the first bracket 143 is connected between one end of the heating tube 141 and the insertion port 123a, and the second bracket 145 is connected between the other end of the heating tube 141 and the air outlet channel 1212. The first bracket 143, the heating tube 141 and the second bracket 145 are sequentially connected to each other to jointly form an atomization channel 140a extending along the first direction. One end of the aerosol generating product 200 can be inserted into the atomization channel 140a through the insertion port 123a.

[0054] In some embodiments, the heating assembly 140 further includes a heat insulation layer 147 and an outer tube 149. The heat insulation layer 147 circumferentially covers the outer wall of the heating tube 141 to prevent the heat generated by the heating tube 141 from dissipating outward into the accommodating cavity 120a and reducing the heat diffusion efficiency. The outer tube 149 has a hollow cylindrical structure with open ends. The outer tube 149 is sleeved on the outside of the heat insulation layer 147, and the two ends of the outer tube 149 are respectively sleeved on the first support 143 and the second support 145. The outer tube 149 is used to fix the heat insulation layer 147 and connect the first support 143 and the second support 145 to form a whole.

[0055] In one specific embodiment, the heat insulation layer 147 is formed of an aerogel material, which possesses excellent heat insulation properties and thus can effectively reduce heat diffusion efficiency. It is understood that the material forming the heat insulation layer 147 is not limited to this, and can be configured as needed to meet different heat insulation requirements.

[0056] like Figure 3 and Figure 4 As shown, in some embodiments, the second support 145 forms a first abutting surface 1452b for abutting the aerosol generating article 200, thereby positioning the aerosol generating article 200 at a preset position in the upper limit of the first direction to ensure the heating efficiency of the aerosol generating article 200.

[0057] Specifically, the second bracket 145 includes a bracket top wall 1452 and a bracket side wall 1454 extending from the edge of the bracket top wall 1452 in the same direction. The end of the second bracket 145 away from the bracket top wall 1452 is sleeved on the outside of one end of the heating tube 141, and the end of the second bracket 145 with the bracket top wall 1452 is inserted into one end of the air outlet channel 1212.

[0058] A circular connecting opening 1452a is provided at the center of the top wall 1452 of the support. The central axis of the connecting opening 1452a coincides with the central axis of the second support 145. The connecting opening 1452a connects the air outlet channel 1212 and the atomizing channel 140a. A first abutting surface 1452b is formed on the side surface of the top wall 1452 of the support facing the heating tube 141, and the first abutting surface 1452b is circular around the connecting opening 1452a in the circumferential direction.

[0059] Thus, by setting the outer diameter of the aerosol generating article 200 to be smaller than the inner diameter of the second support 145 and larger than the inner diameter of the connecting port 1452a, one end face of the aerosol generating article 200 can abut against the first abutting surface 1452b in the first direction. The first abutting surface 1452b can limit the aerosol generating article 200 to a preset position, while the aerosol generated by the aerosol generating article 200 can flow into the gas outlet channel 1212 through the connecting port 1452a.

[0060] In a preferred embodiment, the top wall 1452 of the support has a plurality of connecting grooves on the side surface facing the heating tube 141. All the connecting grooves are arranged at intervals along the circumference, so that the aerosol outside the aerosol generating article 200 can pass through the top wall 1452 of the support and enter the gas outlet channel 1212, thereby increasing the gas outlet volume of the gas outlet channel 1212.

[0061] Please see Figure 5 and Figure 6 In other embodiments, a second abutting surface 1212c for abutting the aerosol generating article 200 is formed in the air outlet channel 1212, thereby positioning the aerosol generating article 200 at a preset position in the upper limit of the first direction to ensure the heating efficiency of the aerosol generating article 200.

[0062] In one specific embodiment, the air outlet channel 1212 includes a first air outlet section 1212a and a second air outlet section 1212b that are connected to each other. The second air outlet section 1212b is located on the side of the first air outlet section 1212a away from the heating tube 141. The inner diameter of the first air outlet section 1212a is larger than the inner diameter of the second air outlet section 1212b. One end of the first air outlet section 1212a connected to the second air outlet section 1212b forms an annular second abutment surface 1212c.

[0063] Thus, by setting the outer diameter of the aerosol generating article 200 to be smaller than the inner diameter of the first air outlet section 1212a and larger than the inner diameter of the second air outlet section 1212b, one end face of the aerosol generating article 200 can abut against the second abutment surface 1212c, and the aerosol generated by the aerosol generating article 200 can directly flow into the air outlet channel 1212.

[0064] Please refer to the previous document. Figure 2 In some embodiments, the atomizing device 100 further includes a power supply assembly 160, which is disposed within the accommodating cavity 120a and located on one side of the heating assembly 140 in the radial direction. The power supply assembly 160 is electrically connected to the heating assembly 140 to provide power to the heating assembly 140. It is understood that the location and internal structure of the power supply assembly 160 are not limited and can be configured as needed to meet different requirements.

[0065] In some embodiments, the atomizing device 100 further includes a circuit board 180, which is disposed within the accommodating cavity 120a and located between the heating component 140 and the power supply component 160. The circuit board 180 is connected to both the power supply component 160 and the heating component 140, and is used to control the power supply component 160 to provide electrical energy to the heating component 140. It is understood that the location and specific shape of the circuit board 180 are not limited and can be configured as needed to meet different requirements.

[0066] During use, the atomizing device 100 described above inserts the aerosol generating product 200 into the atomizing channel 140a through the insertion port 123a. External air enters the aerosol generating product 200 through the end face of the aerosol generating product 200 located outside the atomizing channel 140a, and then carries the aerosol generated by the aerosol generating product 200 under the heating of the heating component 140 and flows out through the air outlet channel 1212.

[0067] Since a portion of the aerosol generating product 200 is inserted into the atomizing channel 140a and connected to the external atmosphere through the air outlet channel 1212, and the other end of the aerosol generating product 200 is located outside the atomizing channel 140a, the aerosol generating product 200 can completely fill the atomizing channel 140a, thereby preventing external cold air from entering the atomizing channel 140a. This causes the aerosol in the atomizing channel 140a to cool and form condensate, which is deposited inside the atomizing channel 140a. This eliminates the hygiene hazards caused by condensate deposition and extends the service life of the atomizing device 100.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
