Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an atomizer and atomizing device. Background Technology

[0002] Electronic atomizers generate aerosols with specific odors through heating and atomization. Users inhale the aerosol through a mouthpiece. However, the high temperature of the aerosol not only causes discomfort such as burning the mouth, reducing the user experience, but also poses potential risks to the oral mucosa and respiratory health due to excessive heat. To address this issue, the following technical methods are employed to improve the situation: 1. Adjusting the heating power to change the aerosol temperature; 2. Lengthening the airway and increasing the heat dissipation area of ​​the airway walls to reduce the aerosol temperature; 3. Employing temperature control technology to control the maximum temperature by detecting changes in the resistance of the heating element.

[0003] However, Method 1 cannot accurately control the temperature of the aerosol and will change the atomization efficiency of the aerosol, affecting the taste; Method 2 has high requirements for structural design, which may increase the size and cost of the electronic atomizer, and the cooling effect is limited, making it difficult to achieve precise control; Method 3 requires specific heating wire materials and more complex control chips, which increases the cost and operational complexity.

[0004] Since the above-mentioned technical means all have certain limitations, such as affecting other performance, being costly, or being unable to directly and effectively control the temperature of the aerosol that is ultimately transmitted to the user's oral cavity, it is of great practical significance to develop a technical solution that can actively, effectively and cost-effectively control the temperature of aerosol.

[0045] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] One of the core concepts of this application is to disclose an atomizer, which includes a housing assembly 10, the housing assembly 10 being provided with spaced air channels 12 and a receiving cavity 11, the receiving cavity 11 being arranged around the air channels 12, wherein one end of the housing assembly 10 forms a mouthpiece 131; a partition 20 is disposed in the receiving cavity 11, the side of the partition 20 facing the mouthpiece 131 forming a first cavity 111 for storing a phase change material, and the side of the partition 20 away from the mouthpiece 131 forming a second cavity 112 for storing an atomizing matrix; and an atomizing component 30, the atomizing component 30 being connected to the second cavity 112 and the air channels 12 respectively.

[0050] In this embodiment, the receiving cavity 11 is divided into a first cavity 111 and a second cavity 112 by a partition 20, with the first cavity 111 located on the side of the second cavity 112 closer to the mouthpiece 131. Since the receiving cavity 11 surrounds the air guide channel 12, after the atomizing component 30 atomizes the atomizing matrix into an aerosol, the aerosol can enter the user's mouth along the air guide channel 12. During the flow of the aerosol in the air guide channel 12, the heat of the aerosol is conducted by the shell component 10 to the phase change material in the first cavity 111. After the phase change material absorbs heat, the aerosol is cooled, allowing it to be inhaled by the user after cooling, thus mitigating the problem of the aerosol burning the user. In this embodiment, the partition 20 can be used to divide a portion of the receiving cavity 11 into the first cavity 111, enabling active, effective, and low-cost control of the aerosol temperature.

[0051] In this embodiment, the atomizer includes a housing assembly 10 and an atomizing assembly 30. The housing assembly 10 is the external structure of the atomizer, and one end of the housing assembly 10 can form a mouthpiece 131. The mouthpiece 131, as the part directly in contact with the user, is the physical medium connecting the atomizer and the user. Figure 1 and Figure 2 As shown, the portion of the housing assembly 10 within the dashed box is used as the suction nozzle 131. The housing assembly 10 is provided with spaced air channels 12 and a receiving cavity 11. The receiving cavity 11 surrounds the air channels 12, which can penetrate the suction nozzle 131, allowing the user to aspirate aerosols entering the air channels 12.

[0052] In some embodiments, the nozzle 131 may be flat, tapered, or elongated, etc. The type of nozzle 131 is not specifically limited in the embodiments of this application.

[0053] In some embodiments, a partition 20 is disposed within the receiving cavity 11. The side of the partition 20 facing the suction nozzle 131 can form a first cavity 111, and the side of the partition 20 away from the suction nozzle 131 can form a second cavity 112, such that the first cavity 111 is positioned close to the suction nozzle 131. The first cavity 111 can store a phase change material. A phase change material is a substance that can undergo a phase change at a specific temperature and absorbs or releases a large amount of latent heat during the phase change process. Its core characteristics revolve around phase change temperature, latent heat performance, and thermal stability. Specifically, a phase change material may change from a solid to a liquid state, or from a liquid to a solid state.

[0054] In some embodiments, the phase change material can be paraffin, fatty acids, or hydrated salts, etc., and the specific material of the phase change material is not limited in the embodiments of this application. The phase change material with a corresponding phase change temperature can be selected according to the applicable scenarios and target audience of the atomizer, as well as the design of different target aerosol temperatures, so as to achieve autonomous control and customization of the atomizer's aerosol temperature, adapting to different user preferences and specific design needs.

[0055] In some embodiments, the phase change temperature of the phase change material can be 4°C-8°C lower than the preset temperature of the aerosol, so that the phase change material can fully absorb heat. The preset temperature of the aerosol is the temperature at which the aerosol is expected to enter the user's mouth, and can be selected according to actual needs.

[0056] In some embodiments, the second chamber 112 may store an atomizing matrix. The atomizing component 30 may be connected to the second chamber 112 and the air guide channel 12 respectively. The atomizing component 30 may receive the atomizing matrix in the second chamber 112 and may heat the atomizing matrix. After being heated, the atomizing matrix vaporizes and condenses upon encountering air to form a high-temperature aerosol. Since the atomizing component 30 is connected to the air guide channel 12, the aerosol may enter the air guide channel 12, thereby enabling the user to inhale the aerosol when using the suction nozzle 131.

[0057] In this embodiment of the application, since the receiving cavity 11 is arranged around the air guiding channel 12, that is, both the first cavity and the second cavity can be arranged around the air guiding channel, and the first cavity 111 is located on the side of the second cavity 112 facing the nozzle 131, thus, taking the nozzle facing upward as an example, the first cavity can be arranged around the upper part of the air guiding channel, and the second cavity can be arranged around the lower part of the air guiding channel.

[0058] After the atomizing component 30 atomizes the atomizing matrix into an aerosol, the aerosol flows through the air guiding channel 12, passing sequentially through the lower and upper parts of the channel before being inhaled by the user. When the aerosol passes through the upper part of the air guiding channel, its heat is conducted through the shell component 10 to the phase change material in the first cavity 111. Since the phase change material absorbs heat, its characteristic of absorbing a large amount of heat during a phase change at a specific temperature effectively cools the aerosol before it is inhaled by the user, thus eliminating the problem of the aerosol burning the user and improving the user experience. In this embodiment, using a phase change material to cool the aerosol is a simple, low-cost, and easy-to-implement method that directly cools the aerosol, achieving active, effective, and low-cost control of the aerosol temperature.

[0059] In this embodiment of the application, by providing a partition 20 in the receiving cavity 11, the receiving cavity 11 can be divided into a first cavity 111 and a second cavity 112 by the partition, so that the phase change material and the atomizing matrix are isolated from each other and do not interfere with each other, preventing mutual contamination, ensuring the independence of their respective functions and product safety. At the same time, the compact design can also simplify the structure of the atomizer and reduce the design difficulty of the atomizer.

[0060] In this embodiment of the application, a suction nozzle 131 is formed at one end of the housing assembly 10, and the housing assembly 10 is provided with a receiving cavity 11. A portion of the receiving cavity 11 is used as a second cavity 112 for storing the atomizing matrix, so that the suction nozzle 131 and the liquid storage shell are integrally formed.

[0061] In some embodiments, the partition 20 and the housing assembly 10 can be integrally formed, or the partition 20 can be fixedly connected to the housing assembly 10 by splicing and fixing methods such as adhesive or snap-fit ​​connection.

[0062] In some embodiments, the housing assembly 10 may include a housing 13, which may include an inner structure 132 and an outer structure 133. The outer structure 133 may be sleeved over the inner structure 132. One end of the outer structure 133 and one end of the inner structure 132 are connected to form a nozzle 131. The inner structure 132 surrounds and forms an air guide channel 12. A receiving cavity 11 is formed between the inner structure 132 and the outer structure 133.

[0063] In this embodiment, the inner layer structure 132 and the outer layer structure 133 are spaced apart, and the outer layer structure 133 is sleeved on the inner layer structure 132. The inner layer structure 132 can enclose and form an air guide channel 12. A receiving cavity 11 can be formed between the inner layer structure 132 and the outer layer structure 133, which facilitates the formation of spaced air guide channels 12 and receiving cavities 11.

[0064] In some embodiments, the gas guiding channel 12 and the receiving cavity 11 can be separated by the inner layer structure 132, that is, the first cavity 111 and the gas guiding channel 12 can be separated by the inner layer structure 132. During the process of the aerosol passing through the gas guiding channel 12, the inner layer structure 132 can conduct heat to the phase change material, thereby achieving cooling of the aerosol.

[0065] In some embodiments, the housing assembly 10 can be a one-piece molded structure, that is, the inner layer structure 132 and the outer layer structure 133 are integrally molded. In other embodiments, the housing assembly 10 can also be a spliced ​​structure, that is, the inner layer structure 132 and the outer layer structure 133 can be spliced ​​and fixed by means of threaded connection or fastening connection.

[0066] In some embodiments, the inner layer structure 132 can be a circular ring structure or a rectangular ring structure, that is, the cross-sectional shape of the inner layer structure 132 can be a circular ring or a rectangle, so that the inner layer structure 132 can enclose and form the air guiding channel 12.

[0067] In some embodiments, the outer structure 133 can be a rectangular ring structure or an elliptical ring structure, that is, the cross-sectional shape of the outer structure 133 can be rectangular or elliptical, or the cross-sectional shape of the outer structure 133 can also be runway-shaped.

[0068] In this embodiment, the outer layer structure 133 is sleeved outside the inner layer structure 132, and the outer layer structure 133 constitutes the external structure of the atomizer.

[0069] In some embodiments of this application, the inner structure 132 may include a first connecting segment 1321 and a second connecting segment 1322 connected to each other. The first connecting segment 1321 is used to enclose and form a first cavity 111, and the second connecting segment 1322 is used to enclose and form a second cavity 112. The wall thickness of the first connecting segment 1321 is less than the wall thickness of the second connecting segment 1322.

[0070] In this embodiment, since the first connecting segment 1321 is used to enclose and form the first cavity 111, the first connecting segment 1321 can conduct the heat of the aerosol to the phase change material during the process of the aerosol passing through the gas guiding channel 12. Because the wall thickness of the first connecting segment 1321 is small, the efficiency of heat conduction to the phase change material can be improved, thereby achieving rapid cooling of the aerosol through the phase change material and reducing the probability of burns to the user.

[0071] In some embodiments, the first connecting segment 1321 and the second connecting segment 1322 can extend along the extension direction of the air guide channel 12. Both the first connecting segment 1321 and the second connecting segment 1322 can be annular structures, specifically circular rings or rectangular rings, etc. The first connecting segment 1321 is located close to the nozzle, and the inner side of the first connecting segment 1321 can enclose to form the upper part of the air guide channel 12, and the inner side of the second connecting segment 1322 can enclose to form the lower part of the air guide channel 12. A first cavity 111 is formed between the outer side of the first connecting segment 1321 and the outer layer structure 133, and a second cavity 112 is formed between the outer side of the second connecting segment 1322 and the outer layer structure 133.

[0072] In some embodiments, the housing assembly 10 may further include a base 14, which may be connected to the end of the outer structure 133 away from the nozzle 131. The first connecting segment 1321, the outer structure 133, and the partition 20 facing the nozzle 131 may be enclosed to form a first cavity 111. The second connecting segment 1322, the outer structure 133, the base 14, and the partition 20 away from the nozzle 131 may be enclosed to form a second cavity 112.

[0073] In some embodiments, the outer layer structure 133 may have a heat-conducting structure on the wall facing the first cavity 111; and / or, the inner layer structure 132 may have a heat-conducting structure on the wall facing the first cavity 111; and / or, the partition 20 may have a heat-conducting structure on the side facing the nozzle 131; wherein the heat-conducting structure includes at least one of protrusions and a metal layer.

[0074] In this embodiment of the application, the heat-conducting structure can be located inside the first cavity 111. By adding the heat-conducting structure, the efficiency of cooling aerosols through phase change materials can be improved.

[0075] In some embodiments, when the heat-conducting structure is a protrusion, the protrusion can be manifested in the form of a flow guide column or particles with increased roughness, which can increase the heat exchange area. In this way, after the shell assembly 10 absorbs the heat of the aerosol, it can be conducted to the phase change material, so that the phase change material can accelerate the heat absorption effect on the shell assembly 10.

[0076] In some embodiments, when the heat-conducting structure is a metal layer, this application does not limit the specific metal material. Since the metal layer has good thermal conductivity, it can improve the effect of the housing assembly 10 in conducting heat to the phase change material.

[0077] In this embodiment, the heat-conducting structure is arranged within the first cavity 111 and can be disposed in at least one of the outer layer structure 133, the inner layer structure 132, and the partition 20. The specific area of ​​the heat-conducting structure is not specifically limited in this embodiment.

[0078] In some embodiments of this application, the partition 20 can be an annular structure, with the inner periphery of the partition 20 sealed to the inner layer structure 132 and the outer periphery of the partition 20 sealed to the outer layer structure 133, so that the partition 20 can divide the receiving cavity 11 into a first cavity 111 and a second cavity 112, and the phase change material and the atomizing matrix can be separated by the partition 20.

[0079] In some other embodiments of this application, the partition 20, the outer structure 133, and the inner structure 132 can be integrally formed to improve the structural stability of the atomizer.

[0080] In some embodiments, the side of the partition 20 facing the nozzle 131 can be enclosed with the housing assembly 10 to form a first cavity 111, and the side of the partition 20 away from the nozzle 131 can be enclosed with the housing assembly 10 to form a second cavity 112, such that the axial direction of the partition 20 is parallel to the extension direction of the air guide channel 12, and the first cavity 111 is disposed between the nozzle 131 and the second cavity 112, which is beneficial to ensure that the heat absorption characteristics of the phase change material can be used to cool the aerosol.

[0081] In some embodiments of this application, a filling hole 1331 may be provided on the outer side of the housing assembly 10. The filling hole 1331 is connected to the first cavity 111. In this way, phase change material can be filled into the first cavity 111 through the filling hole 1331, which is more convenient and reliable.

[0082] In some embodiments of this application, the atomizer may also include a sealing plug that fills the filler hole 1331, or the sealing plug may be removably plugged into the filler hole 1331.

[0083] In this embodiment, after the sealing plug is removed, phase change material can be added into the first cavity 111 through the filling hole 1331, making the filling method of phase change material relatively simple and convenient. After filling the first cavity 111 with phase change material, the sealing plug can be used to fill the filling hole 1331 to seal the first cavity 111 and prevent leakage of phase change material.

[0084] In some embodiments, the sealing plug can be filled into the filler hole 1331 by injection sealing, making the sealing plug non-removable.

[0085] In other embodiments, the sealing plug can also be filled into the packing hole 1331 by means of snap-fit ​​or interference fit, so that the sealing plug is removable and the phase change material is easy to replace. This allows the goal of autonomously controlling the aerosol temperature by selecting materials with different properties, thus meeting the aerosol temperature requirements of different users or products.

[0086] In some embodiments, the sealing plug can be made of plastic or silicone, for example, silicone is used to make the sealing plug so that the sealing plug can be inserted into the filling hole 1331 by interference fit.

[0087] In some embodiments of this application, the filling hole 1331 is filled with sealant to seal the filling hole 1331 and prevent leakage of the phase change material.

[0088] In the embodiments of this application, there are diverse choices of phase change materials and diverse ways of sealing the filler holes 1331. These methods can simplify the production and assembly process of the atomizer, ensure the reliability of phase change material filling and the sealing of the filler holes 1331, and facilitate the large-scale production of the atomizer.

[0089] In some embodiments, the packing hole 1331 may be formed in the outer structure 133 of the housing assembly 10. The shape of the packing hole 1331 may be a regular circle, ellipse or polygon, or it may be an irregular shape. In the embodiments of this application, the specific shape of the packing hole 1331 is not limited.

[0090] In some embodiments, the number of packing holes 1331 may be one, or at least two, and at least two packing holes 1331 may be arranged at circumferential intervals along the outer layer structure 133, such as... Figure 3 This illustrates a case where two packing holes 1331 are provided circumferentially along the outer layer structure 133.

[0091] In some embodiments, the filling hole 1331 may be spaced apart from the position where the nozzle 131 contacts the user, so that the sealing plug does not affect the user's experience.

[0092] In some embodiments, the filling hole 1331 may also be located close to the position where the nozzle 131 contacts the user, or the user may directly contact the location of the filling hole 1331. In this case, edible sealant may be used to seal the filling hole 1331, so that the sealant may be flush with the outer surface of the outer structure 133 of the housing assembly 10, or the sealing plug may be flush with the outer surface of the outer structure 133 of the housing assembly 10.

[0093] In some embodiments, the opening size of the packing hole 1331 can be D, where 1mm ≤ D ≤ 5mm.

[0094] In this embodiment of the application, the opening size of the packing hole 1331 is limited to the range of 1mm-5mm. This can avoid the problems that the packing hole 1331 is too small to be opened and that it is not easy to add the phase change material into the first cavity 111. It can also avoid the problems that the packing hole 1331 is too large to be sealed and that the sealing plug comes into contact with the user's mouth.

[0095] In some embodiments, the opening size D of the packing orifice 1331 is in the range of 1mm-5mm, which can be understood as both the maximum and minimum opening sizes of the packing orifice 1331 being in the range of 1mm-5mm. For example, when the packing orifice 1331 is a circular orifice, the diameter of the packing orifice 1331 is in the range of 1mm-5mm; when the packing orifice 1331 is an elliptical orifice, both the major and minor axes of the packing orifice 1331 are in the range of 1mm-5mm.

[0096] For example, the opening size D of the packing hole 1331 can be 1mm, 1.5mm, 2mm, 2.6mm, 3mm, 3.3mm, 4mm or 5mm, etc.

[0097] In some embodiments, since the phase change material can undergo a phase change, the size of the filling orifice 1331 can be designed according to the morphology of the phase change material. For example, the phase change material can be injected into the first cavity 111 when it is in a liquid state, for example, by heating the phase change material to a molten state. In this case, the phase change material can flow, and the opening size D of the filling orifice 1331 can be controlled within the range of 1mm-3mm, making the opening size of the filling orifice 1331 relatively small. Alternatively, the phase change material can also be filled into the first cavity 111 when it is in a solid state, for example, the phase change material can be in powder or granular form. In this case, the opening size D of the filling orifice 1331 can be controlled within the range of 3mm-5mm, and the filling orifice 1331 can be designed to be larger to facilitate the filling of powder or granular phase change material.

[0098] In some embodiments, the opening size D of the filling hole 1331 is designed to be in the range of 1mm-2mm, so that the size of the filling hole 1331 is small. In this case, a sealing plug can be omitted, and the filling hole 1331 can be sealed directly with sealant. The sealant can be food-grade sealant to improve the safety of the atomizer.

[0099] In some embodiments of this application, the phase change material accounts for 70%-90% of the volume of the first cavity 111; the maximum heat absorption of the phase change material during phase change is Q1, and the heat released by the aerosol when it cools down to a preset temperature is Q2, where Q2≤Q1.

[0100] In this embodiment of the application, by controlling the volume ratio of the phase change material to the first cavity 111 to 70%-90% and by setting Q2≤Q1, it is easy to ensure that the phase change material can absorb heat, so as to reduce the temperature of the aerosol to a preset temperature or below, and avoid the user being burned.

[0101] In some embodiments, since the volume of the phase change material may change during the phase change, the amount of phase change material should be less than the volume of the first cavity 111. If the amount of phase change material is too small, the phase change material cannot effectively absorb the heat of the aerosol, and cannot cool the aerosol to a preset temperature or below. Therefore, in the embodiments of this application, in order to meet the volume change of the phase change material and ensure that the phase change material can absorb sufficient heat, the volume ratio of the phase change material to the first cavity 111 is controlled within the range of 70%-90%. For example, the volume ratio of the phase change material to the first cavity 111 can be 70%, 72%, 75%, 78%, 80%, 83%, 85%, 89%, or 90%, etc.

[0102] In some embodiments, the preset temperature can be set according to actual needs, and Q2 is the amount of heat that needs to be released to cool the aerosol to the preset temperature.

[0103] In some embodiments of this application, Q1 ≥ 1.5Q2 to further ensure that the phase change material can absorb enough heat to cool the aerosol below a preset temperature.

[0104] In some embodiments, Q1 = ρ PCM V PCM h PCM , where ρ PCM V PCM 、 and h PCM These represent the density, volume, and enthalpy of the phase change material, respectively. Q2=ρ air V air C p，ai rΔT, where ρ air V air and C p,air These represent the density, volume, and enthalpy of phase transition of the aerosol, ρ. air V air and C p,air The density, volume, and specific heat capacity of air can be used as approximations, where ΔT is the difference between the temperature of the aerosol before it cools down and the preset temperature.

[0105] Based on the above formula, the filling volume of the first cavity 111 can be determined. At the same time, the design volume of the first cavity 111 can be calculated from the volume ratio of the phase change material to the first cavity 111.

[0106] In the embodiments of this application, the temperature of the aerosol can be controlled within a reasonable range through reasonable design, so as to improve the user's comfort and safety.

[0107] In some embodiments of this application, the preset temperature of the aerosol can be designed to be 55°C, and a paraffin mixture with a phase change temperature of 50°C can be used as the phase change material. In its molten state, the paraffin mixture can be injected into the first cavity 111 using a syringe, controlling the volume percentage of the paraffin mixture in the first cavity 111 to be 85%, and the pore size of the filling hole 1331 to be 1 mm. After the paraffin mixture is injected, food-grade sealant is used to seal the filling hole 1331 to ensure that the first cavity 111 does not leak.

[0108] In some embodiments of this application, the extension length of the first cavity 111 along the extension direction of the air guide channel 12 can be L, where 10mm≤L≤50mm.

[0109] In this embodiment of the application, by controlling the extension length L of the first cavity 111 along the extension direction of the air guide channel 12 to be greater than or equal to 10 mm and less than or equal to 50 mm, the aerosol can be cooled down in time under the heat absorption effect of the phase change material during the flow in the air guide channel 12, and can be drawn in by the user after being cooled down to the preset temperature, which can effectively prevent the user from being burned.

[0110] For example, along the extension direction of the air guide channel 12, the extension length of the first cavity 111 can be L, which can be 10mm, 15mm, 20mm, 28mm, 30mm, 38mm, 40mm, 45mm or 50mm, etc.

[0111] In some embodiments of this application, the atomizing component 30 includes an atomizing tube 31, a heating element 33, and a liquid guiding element 32. The atomizing tube 31 is sealed to the inner layer structure 132. An atomizing channel communicating with the air guiding channel 12 is formed inside the atomizing tube 31. The heating element 33 and the liquid guiding element 32 are both disposed in the atomizing channel. The atomizing tube 31 is also provided with a liquid guiding hole 311 communicating with the second cavity 112. The liquid guiding element 32 abuts against the heating element 33 and covers at least a portion of the liquid guiding hole 311, for guiding the atomizing matrix to the heating element 33.

[0112] In this embodiment, the atomizing matrix in the second cavity 112 can flow to the liquid guide 32 through the liquid guide hole 311. The liquid guide 32 can guide the atomizing matrix to the heating element 33. The heating element 33 can heat the atomizing matrix. After being heated, the atomizing matrix vaporizes and forms an aerosol together with the air entering from the outside. The aerosol can enter the air guide channel 12 along the atomizing channel, thereby being inhaled by the user.

[0113] In some embodiments, the heating element 33 can be a heating wire or a heating mesh, etc. When the heating wire is energized, it heats the atomizing matrix, causing the atomizing matrix to boil and vaporize, and combine with the incoming cold air to condense into small droplet particles, which together with the air form an aerosol. The liquid guiding element 32 can be oil-wicking cotton or polymer cotton, etc., and this embodiment does not specifically limit it.

[0114] In some embodiments, the liquid guiding hole 311 can be a circular hole, an elliptical hole, or a polygonal hole, etc., and this application does not specifically limit it.

[0115] In some embodiments, the atomizing tube 31 can be connected to the inner layer structure 132 of the housing 13 to facilitate the connection between the atomizing channel and the air guiding channel 12. The connection between the two can be a snap-fit ​​or a fastening connection, etc.

[0116] In some embodiments of this application, the atomizer further includes a sealing element 50, and the housing assembly 10 further includes a base 14. The base 14 is connected to the end of the outer structure 133 away from the mouthpiece 131, and the sealing element 50 is respectively sealed to the outer structure 133 and the base 14; wherein, the atomizing component 30 passes through the sealing element 50 and is sealed to the sealing element 50, and the atomizing component 30 is sealed to the inner structure 132.

[0117] In this embodiment, before the sealing element 50 and the base 14 are installed, the end of the second cavity 112 away from the nozzle 131 is open, facilitating the injection of the atomizing matrix into the second cavity 112 through this opening. After assembling the sealing element 50 and the base 14, the end of the second cavity 112 away from the nozzle 131 can be sealed, thus sealing the second cavity 112 and preventing leakage of the atomizing matrix.

[0118] In some embodiments, the sealing element 50 is respectively sealed to the housing 13 and the base 14, and one end of the atomizing tube 31 can be sealed to the inner layer structure 132. The end of the atomizing tube 31 away from the inner layer structure 132 passes through the sealing element 50 and is sealed to it, so that the sealing element 50 can play a good sealing role and prevent leakage of the atomizing matrix in the second cavity 112. The sealing element 50 can be made of silicone or plastic, etc., to ensure the sealing performance of the sealing element 50.

[0119] In some embodiments, the seal 50 can be interference-fitted with the outer structure 133 to achieve a sealed connection between the seal 50 and the outer structure 133. The seal 50 can also be snap-fitted with the base 14 to achieve a sealed connection between the seal 50 and the base 14.

[0120] In some embodiments, the base 14 can also be fastened to the outer structure 133 to ensure the reliability of the connection between the base 14 and the housing 13.

[0121] In some embodiments, both the seal 50 and the base 14 are removable, which allows for repeated injection of the atomizing matrix into the second chamber 112, thereby improving the service life of the atomizer.

[0122] For example, the assembly process of the atomizer may include the following steps: first, place the atomizer upright, i.e., with the mouthpiece 131 at the top, add phase change material into the first chamber 111 through the filling hole 1331, then seal the filling hole 1331 with a sealing plug or sealant, then place the atomizer upside down, i.e., with the mouthpiece 131 at the bottom, inject the atomizing matrix into the second chamber 112, and then assemble the sealing member 50 and the base 14.

[0123] In some embodiments of this application, the base 14 is provided with an air guide hole 141, which is connected to the atomization channel and is used to connect to the outside.

[0124] In this embodiment, outside air can enter the atomization channel through the air guide hole 141. In this way, after the heating element 33 heats the atomization matrix, the heated and vaporized atomization matrix condenses upon encountering air to form a high-temperature aerosol, which can improve the reliability of the atomizer in generating aerosol.

[0125] In some embodiments, the shape of the air guide hole 141 can be a regular shape such as a circular hole or an elliptical hole, or it can be an irregular shape. The number of air guide holes 141 can be at least one, and this application does not specifically limit this.

[0126] In this embodiment, when a user inhales through the mouthpiece 131, air enters the atomization channel through the air guide hole 141. The atomization matrix is ​​guided to the heating element 33 through the liquid guide 32. The atomization matrix is ​​heated and vaporized. Upon encountering the cold air entering the atomization channel, it condenses to form a high-temperature aerosol. The aerosol enters the air guide channel 12 from the atomization channel and flows to the area where the first cavity 111 is located. The shell assembly 10 can transfer heat to the phase change material. The phase change material can absorb heat and undergo a solid-to-liquid or other types of phase change. During this process, the temperature of the phase change material remains basically unchanged, thereby absorbing a large amount of heat from the aerosol, causing the aerosol temperature to drop significantly. The cooled aerosol then reaches the user's mouth through the mouthpiece 131. When the user stops inhaling, the phase change material gradually dissipates heat and solidifies, returning to its initial state, preparing for the next heat-absorbing phase change.

[0127] In some embodiments of this application, the atomizer further includes an adapter 70, which has a through hole that can communicate with the air guide channel 12 and the atomization channel respectively; one end of the adapter 70 can be interference-fitted with the inner layer structure 132, and the other end can be snapped into the atomization tube 31.

[0128] In this embodiment, the adapter 70 can indirectly fix the atomizing tube 31 to the inner layer structure 132, which can improve the convenience of assembling the atomizing tube 31 and the inner layer structure 132, thereby improving the convenience of assembling the atomizing component 30 and the shell component 10.

[0129] In some embodiments, one end of the adapter 70 may be embedded within the air duct 12. In other embodiments, the adapter 70 may be fitted onto the inner structure 132.

[0130] In some embodiments, the other end of the adapter 70 can be snapped into the atomizing tube 31 via a snap-fit, or it can be snapped into place via a tongue-and-groove fit. For example... Figure 3 As shown, this illustrates a case where the other end of the adapter 70 is fitted with an atomizing tube 31 via a groove. Other cases can be set similarly, but this application does not impose specific limitations on this aspect.

[0131] In some embodiments, to further ensure the sealing of the connection between the atomizing tube 31 and the inner structure 132, the adapter 70 may also be made of silicone or plastic.

[0132] The atomizer described in this application embodiment is compared with a comparative example. The difference between the atomizer in the comparative example and the atomizer in this application is that the comparative example does not have a first chamber 111 and a phase change material, while the atomizer in this application has a first chamber 111 and a phase change material. During the test, a thermocouple was used to measure the aerosol temperature at the center point of the nozzle 131. A suction machine was used to aspirate the atomizer, with a suction time of 2 seconds followed by a 15-second interval, and a suction flow rate of 17.5 mL / s. The test results are as follows. Figure 4 As shown, in the comparative example, the highest temperature of the air outlet of the atomizer 131 is 84.9℃. The atomizer in this application can effectively control the highest temperature of the air outlet of the atomizer 131 during atomization at about 55℃, indicating that the use of phase change materials to control the temperature of aerosol in this application is very effective.

[0133] This application achieves effective control of aerosol temperature by setting a first chamber 111 in the atomizer, filling it with phase change material, and utilizing the heat absorption properties of the phase change material. This method is simple in structure, low in cost, and allows for customized smoke temperature control by selecting phase change materials with different phase change temperatures, significantly improving user experience and product safety. The phase change material filling and sealing scheme provided in this application also offers flexible and convenient options for actual production.

[0134] The atomizer described in the embodiments of this application has at least the following advantages:

[0135] In this embodiment, the receiving cavity is divided into a first cavity and a second cavity by a partition, with the first cavity located on the side of the second cavity closer to the mouthpiece. Since the receiving cavity surrounds the air guide channel, after the atomizing component atomizes the atomizing matrix into an aerosol, the aerosol can enter the user's mouth along the air guide channel. During the flow of the aerosol in the air guide channel, the heat of the aerosol is conducted by the shell assembly to the phase change material in the first cavity. After the phase change material absorbs heat, the aerosol is cooled, allowing it to be inhaled by the user after cooling, thus mitigating the problem of the aerosol burning the user. In this embodiment, a portion of the receiving cavity can be separated by a partition for use as the first cavity, enabling active, effective, and low-cost control of the aerosol temperature.

[0136] Secondly, this application also discloses an atomizing device, which may include a power supply and the aforementioned atomizer. The power supply may be assembled with the housing assembly 10 and electrically connected to the atomizing assembly 30 for supplying power to the atomizing assembly 30.

[0137] In this embodiment, the power supply can supply power to the atomizing component 30, so that the atomizing component 30 can be energized to heat and atomize the atomizing matrix to form an aerosol.

[0138] In some embodiments, the power supply may include a mounting base and a power supply component. The mounting base may be assembled with the housing assembly 10 and enclose to form a receiving space. The power supply component may be disposed within the receiving space and electrically connected to the atomizing assembly 30.

[0139] In some embodiments, the power supply component may include a battery and a circuit board, the battery may be electrically connected to the circuit board, and the heating element 33 of the atomizing component 30 may be electrically connected to the circuit board, so that the atomizing component 30 is connected to a power source.

[0140] In some embodiments, the atomizer may also be provided with a conductive element 80, and the power supply assembly may also include an electrical connector connected to the circuit board. The conductive element 80 may be electrically connected to the pins of the heating element 33. After the atomizer and the power supply are assembled, the conductive element 80 may contact the electrical connector to achieve electrical conduction.

[0141] In some embodiments, the conductive element 80 may be a conductive post or a conductive pin, and the electrical connector may be a conductive spring or a metal spring, etc.

[0142] The atomizing device described in this application embodiment has the same beneficial effects as an atomizer, and will not be repeated here.
