[0015] In one embodiment, the center axes of the atomizing body, the first sensing unit, and the second sensing unit coincide with each other.

[0016] In one embodiment, the atomizing body includes a suction nozzle section and an atomizing section that are interconnected, the atomizing section includes the atomizing medium, the first sensing unit and the second sensing unit are both located in the atomizing section, and an air inlet connected to the outside world is provided on the suction nozzle section near the atomizing section.

[0017] In one embodiment, the atomization section further includes a non-air-permeable wrapping layer, and the atomization medium is wrapped in the wrapping layer.

[0019] In one embodiment, the second end is closer to the mouthpiece segment than the first end, and the distance between the second end and the first end along the axial direction of the atomizing body is 0.5 mm to 2 mm.

[0020] In one embodiment, the first sensing unit is a columnar structure and includes a support member and a heating member. The heating member is sleeved on the support member, and the length of the heating member is smaller than the length of the support member.

[0034] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "inner," "outer," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0036] See Figure 1 、 Figure 2 and Figure 3 , the atomizing medium carrier 10 provided by one embodiment of the present invention is used in conjunction with a heating atomizing device 20 so that the atomizing medium carrier 10 is atomized to form an aerosol that can be inhaled by the user. A accommodating chamber 21 is provided in the heating atomizing device 20, and the heating atomizing device 20 includes a battery 25, a control chip 26 and a coil 27. The battery 25 is electrically connected to the control chip 26 and the coil 27 at the same time. The control chip 26 is used to control the power supply of the battery 25 to the coil 27. For example, it can control whether the battery 25 stops or continues to supply power to the coil 27, and can also control the power of the battery 25 to the coil 27. The coil 27 is arranged around the accommodating chamber 21. When the battery 25 supplies power to the coil 27, the coil 27 generates an alternating magnetic field whose intensity changes with time, and the accommodating chamber 21 will be within the coverage range of the alternating magnetic field.

[0037] The accommodating chamber 21 is actually an open chamber, and an open opening 22a is formed on the outer surface of the heating atomizing device 20. Obviously, the open opening 22a is directly connected to the outside world. The accommodating chamber 21 can be divided into two sections, that is, the accommodating chamber 21 includes a first accommodating section 22 and a second accommodating section 23 that are connected to each other. The open opening 22a is located on the first accommodating section 22, so that the first accommodating section 22 is located above the second accommodating section 23. The caliber of the first accommodating section 22 is unevenly set. For example, along the direction away from the open opening 22a, that is, from top to bottom, the caliber of the first accommodating section 22 can gradually decrease, so that the first accommodating section 22 is roughly a conical structure with a larger top and a smaller bottom. The caliber of the second accommodating section 23 can be evenly set, so that the second accommodating section 23 is a columnar structure, and the caliber of the second accommodating section 23 can be smaller than the caliber of the first accommodating section 22.

[0038] In some embodiments, the atomizing medium carrier 10 includes a first sensing unit 100, a second sensing unit 200 and an atomizing body 300. The atomizing body 300 can be roughly cylindrical in structure. The atomizing body 300 includes a mouthpiece section 310 and an atomizing section 320. The atomizing section 320 includes an atomizing medium 321 and a wrapping layer 322. The atomizing medium 321 is used to atomize to form an aerosol. The wrapping layer 322 can be a non-air-permeable structure. The atomizing medium 321 is wrapped in the wrapping layer 322. Of course, the wrapping layer 322 can also be an air-permeable structure. An air inlet 311 is provided on the mouthpiece section 310 near the atomizing section 320. The air inlet 311 can be connected to the outside world. The end of the mouthpiece section 310 away from the atomizing section 320 is the mouthpiece end 312, and the user inhales the aerosol through the mouthpiece end 312.

[0039] The diameter of the atomizing medium carrier 10 can be roughly equal to the caliber of the second accommodating section 23. When the atomizing medium 321 is received in the accommodating chamber 21 through the open opening 22a, the atomizing section 320 cooperates with the second accommodating section 23, and no gap exists between the atomizing section 320 and the inner wall surface 24 of the second accommodating section 23. In other words, the atomizing section 320 and the second accommodating section 23 form a relatively tight fit. The nozzle section 310 has a nozzle end 312 with a portion located outside the first accommodating section 22 for user inhalation, and the other portion of the nozzle section 310 is accommodated within the first accommodating section 22. The air inlet 311 is located within the first accommodating section 22. An air inlet gap 22b of a certain width exists between the nozzle section 310 and the inner wall surface 24 of the first accommodating section 22. Obviously, the air inlet gap 22b is directly connected to the outside world through the open opening 22a, and the air inlet 311 is connected to the air inlet gap 22b.

[0040] When a user draws air at the mouthpiece end 312 of the mouthpiece section 310, external air enters the mouthpiece section 310 through the open opening 22a, the air inlet gap 22b, and the air inlet hole 311 in sequence. Atomized particles generated by the atomization of the atomizing medium 321 in the atomizing section 320 are then inhaled into the mouthpiece section 310. The external air in the mouthpiece section 310 mixes with the atomized particles to form an aerosol that is then inhaled by the user. Figure 3 The direction indicated by the dashed arrow is the direction of gas flow. Therefore, when the atomized medium 321 within the atomizing section 320 is atomizing, it is difficult for external gas to enter the atomizing section 320, causing the atomized medium 321 to be in a low-oxygen (oxygen-deficient) baking environment. This, on the one hand, eliminates harmful substances or odorous substances produced by the reaction of the atomized medium 321 with oxygen, thereby improving the safety of the atomized medium carrier 10. On the other hand, it can also change the composition and concentration of the aerosol to a certain extent, thereby making the entire atomized medium carrier 10 have a more fragrant and pure taste.

[0041] In some embodiments, the first sensing unit 100 is housed within the atomizing section 320 such that the first sensing unit 100 is covered by the atomized medium 321, i.e., the first sensing unit 100 is in direct contact with the atomized medium 321. The centerline axis of the first sensing unit 100 can coincide with the centerline axis of the atomizing body 300. In layman's terms, the first sensing unit 100 is centrally located within the atomizing section 320.

[0042] See Figure 4, the first induction unit 100 can be a columnar structure. From the perspective of the composition structure, the first induction unit 100 includes a support member 110 and a heating element 120, for example, a cylindrical or prismatic structure. The support member 110 can be made of a weakly magnetic material such as a metal with high thermal conductivity or a non-metal. The thermal conductivity of the support member 110 can be not less than 20W·m / K. For example, the support member 110 can be made of one or more of aluminum, copper, carbon rod or high thermal conductivity ceramic material. When the support member 110 is made of a porous material such as carbon, the weight of the first induction unit 100 can be reduced, thereby reducing the weight of the entire atomizing medium carrier 10. The heating element 120 is made of a strong magnetic material. For example, the heating element 120 can be made of one or more of stainless steel, nickel and nickel-based alloys or iron and iron-based alloys, so that the heating element 120 generates heat under the action of an alternating magnetic field. Specifically, the alternating magnetic field will cause a large amount of eddy currents to form in the heating element 120, and the eddy currents will have a thermal effect and cause the heating element 120 to generate heat. The Curie temperature of the heating element 120 can be 250°C to 350°C, for example, 260°C to 290°C. When the temperature of the heating element 120 reaches the Curie temperature, the magnetism of the heating element 120 disappears and the heating element 120 can no longer generate heat. When the temperature of the heating element 120 is lower than the Curie temperature, the magnetism of the heating element 120 is restored and heat is generated. This can prevent the heating element 120 from overheating, and the heating temperature of the heating element 120 during normal operation can be controlled to be less than or equal to its own Curie temperature.

[0043] The cross-sectional dimension of the first sensing unit 100 is 1.5 mm to 2.5 mm, for example, 1.8 mm to 2 mm. When the first sensing unit 100 is a cylindrical structure, the cross-sectional dimension is actually the diameter of the first sensing unit 100. The support member 110 is a cylindrical structure, the heating element 120 is a tubular structure, and the heating element 120 is sleeved on the support member 110. The thickness of the heating element 120 is its own wall thickness. When the heating element 120 is a cylindrical structure, the thickness of the heating element 120 is half the difference between its outer diameter and inner diameter. The thickness of the heating element 120 is 10 μm to 150 μm, for example, 12 μm to 50 μm. The length of the heating element 120 along its own axis is 8 mm to 15 mm, for example, 10 mm to 12 mm. The length of the heating element 120 can be less than the length of the support member 110.

[0044] See Figure 5, the first induction unit 100 can also be a sheet-like structure. From the perspective of the composition structure, the first induction unit 100 includes a sheet-like heating sheet 130. The heating sheet 130 is made of a strong magnetic conductive material. For example, the heating sheet 130 can be made of one or more of stainless steel, nickel and nickel-based alloys or iron and iron-based alloys, so that the heating sheet 130 generates heat under the action of the alternating magnetic field. Specifically, the alternating magnetic field will cause a large amount of eddy current to form in the heating sheet 130. The eddy current will have a thermal effect and cause the heating sheet 130 to generate heat. The Curie temperature of the heating sheet 130 can be 250°C to 350°C, for example, 260°C to 290°C. The thickness of the heating sheet 130 can be 10μm to 150μm, for example, 10mm to 12mm. With the nozzle end 312 on the nozzle section 310 as a reference, the heating plate 130 has a lower end 132 and an upper end 131, and the upper end 131 is closer to the nozzle end 312 relative to the lower end 132. Obviously, the upper end 131 is also closer to the entire nozzle section 310 relative to the lower end 132. The width of the heating plate 130 can gradually increase in the direction from the upper end 131 to the lower end 132, so that the heating plate 130 is roughly an isosceles trapezoid or an isosceles triangle. The width A of the upper end 131 is 0mm to 5mm, and the width B of the lower end 132 is 3mm to 5mm. When the width A of the upper end 131 is zero, the heating plate 130 is roughly an isosceles triangle. When the width A of the upper end 131 is greater than zero, the heating plate 130 is roughly an isosceles trapezoid.

[0045] When the atomized medium carrier 10 is housed in the receiving chamber 21 of the heating atomizing device 20, the first induction unit 100 generates heat under the action of the alternating magnetic field generated by the coil 27. Since the first induction unit 100 is in direct contact with the atomized medium 321, this heat is transferred from the centerline area of ​​the atomizing section 320 to the edge areas through the atomized medium 321, thereby heating and atomizing the atomized medium 321 located in the center and edge areas of the atomizing section 320. Therefore, the first induction unit 100 heats the atomized medium 321 in a central heating mode.

[0046] The first sensing unit 100 may also include a ceramic layer or a glass glaze layer, which covers the surface of the heating element 120. The ceramic layer or the glass glaze layer has a small friction coefficient and its surface is extremely smooth. On the one hand, it can effectively prevent the solidified material produced by the atomizing medium 321 during the atomization process from adhering to the ceramic layer or the glass glaze layer, and prevent the solidified material from producing particles or gases that affect the user's inhalation taste during the heating process. On the other hand, during the assembly process of the atomizing medium carrier 10, the first sensing unit 100 needs to be inserted into the atomizing section 320. This can reduce the frictional resistance between the first sensing unit 100 and the atomizing section 320, avoid the first sensing unit 100 from bending under the action of large frictional resistance, ensure that the first sensing unit 100 is smoothly inserted into the atomizing medium carrier 10, and improve the assembly efficiency of the entire atomizing medium carrier 10.

[0047] See Figure 1 From the perspective of the connection position, the first sensing unit 100 may include a base section 140 and a spike section 150. The spike section 150 is located above the base section 140, so that the spike section 150 is arranged closer to the nozzle section 310 relative to the base section 140. The cross-sectional dimensions of the base section 140 can be kept constant and uniformly set, while the cross-sectional dimensions of the spike section 150 vary rather than being uniformly set. From the base section 140 to the direction of the spike section 150, that is, from bottom to top, the cross-sectional dimensions of the spike section 150 can gradually decrease, so that the spike section 150 has a roughly conical structure. By providing the spike section 150, the fitting resistance of the first sensing unit 100 during the insertion into the atomizing section 320 can be reduced, thereby preventing the first sensing unit 100 from bending due to excessive resistance, and also improving the assembly efficiency of the atomizing medium carrier 10.

[0048] See Figure 1In some embodiments, the second induction unit 200 can be a tubular structure, such as a cylindrical structure. The second induction unit 200 is sleeved on the wrapping layer 322 of the atomization section 320. The second induction unit 200 can be made of a strong magnetic conductive material, such as one or more of ferrite, nickel-based alloy or iron-based alloy. Similar to the heating element 120 in the first induction unit 100, under the action of the alternating magnetic field, a large amount of eddy current is formed in the second induction unit 200 to generate heat. The Curie temperature of the second induction unit 200 is 150°C to 220°C, for example, 180°C to 220°C. Given that the Curie temperature of the first induction unit 100 is 250°C to 350°C, the Curie temperature of the second induction unit 200 is lower than the Curie temperature of the first induction temperature. During operation, the heating temperature formed by the first induction unit 100 can be higher than the heating temperature formed by the second induction unit 200. The thickness of the second sensing unit 200 is 0.015 mm to 0.3 mm, for example, 0.1 mm to 0.2 mm. This thickness is actually the wall thickness of the cylindrical second sensing unit 200. When the second sensing unit 200 is cylindrical, the thickness of the second sensing unit 200 is half the difference between its outer diameter and inner diameter. The axial length of the second sensing unit 200 can be 0.8 mm to 2.5 mm, for example, 1 mm to 1.5 mm. The central axis of the second sensing unit 200 can coincide with the central axis of the atomizing body 300.

[0049] When the atomized medium carrier 10 is housed in the accommodating chamber 21 of the heating atomizing device 20, and given that the second sensing unit 200 is in direct contact with the atomizing section 320, when the second sensing unit 200 generates heat under the action of the alternating magnetic field, this heat is transferred from the edge region of the atomizing section 320 to the center region through the wrapping layer 322 and the atomized medium 321, thereby heating and atomizing the atomized medium 321 located in the center and edge regions of the atomizing section 320. Therefore, the second sensing unit 200 heats the atomized medium 321 in an edge heating mode.

[0050] The second sensing unit 200 can be set at a position of the atomizing section 320 close to the mouthpiece section 310. The length of the second sensing unit 200 can be smaller than the length of the heating element 120 and the heating plate 130 on the first sensing unit 100, so that the second sensing unit 200 covers part of the heating element 120 and the heating plate 130 in the positive projection of the first sensing unit 100. In this way, the electromagnetic shielding effect of the cylindrical second sensing unit 200 on the first sensing unit 100 can be prevented, ensuring that the first sensing unit 100 and the second sensing unit 200 can both generate heat at the same time, so that the atomized medium 321 can simultaneously form a center heating mode and an edge heating mode.

[0051] See Figure 6When the first sensing unit 100 has a spike segment 150, the upper end of the spike segment 150 is closer to the mouthpiece segment 310 than its lower end, and the upper end of the spike segment 150 is recorded as the first end 151. The upper end of the second sensing unit 200 is closer to the mouthpiece segment 310 than its lower end, and the upper end of the second sensing unit 200 is recorded as the second end 210. The second end 210 is closer to the mouthpiece segment 310 than the first end 151, so that the first end 151 and the second end 210 are spaced apart along the axial direction of the atomizing body 300 to form a certain spacing H, and the value of the spacing H is 0.5mm to 2mm. Given that the heating temperature of the first end 151 of the spike segment 150 is relatively low, this heating temperature can be compensated by the operation of the second sensing unit 200, thereby ensuring that the atomized medium 321 in the entire atomizing section 320 is heated evenly. In other embodiments, the value of the spacing H can also be equal to zero.

[0052] See Figure 3 and Figure 7 When using the heating atomization device 20 to heat and atomize the atomized medium carrier 10, the atomized medium carrier 10 can be inserted into the accommodating chamber 21. When a user draws inhalation from the mouthpiece section 310, the battery 25 powers the coil 27 to generate an alternating magnetic field, causing the first and second induction units 100, 200 to simultaneously generate heat under the action of the alternating magnetic field, ensuring that the atomized medium 321 can simultaneously form a center heating mode and an edge heating mode. During operation, the temperature of the first induction unit 100 rises linearly and continuously between time zero and time t1, allowing the temperature of the first induction unit 100 to rise to heating temperature T1 at time t1 and remain constant at heating temperature T1 for the subsequent time period. The temperature of the second induction unit 200 rises linearly and continuously between time zero and time t1, allowing the temperature of the second induction unit 200 to rise to heating temperature T2 at the same time t1 and remain constant at heating temperature T2 for the subsequent time period, with heating temperature T1 being greater than heating temperature T2. Therefore, the heat mainly comes from the first induction unit 100, forming an operating mode in which the first induction unit 100 is the primary heating unit and the second induction unit 200 is the secondary heating unit. Therefore, under the action of the alternating magnetic field generated by the heating atomization device 20, the atomized medium carrier 10 can generate heat itself, that is, the atomized medium carrier 10 has self-heating properties.

[0053] If the atomizing medium carrier 10 only has the first sensing unit 100 and only forms a central heating mode, when the first sensing unit 100 is operating, heat can only be transferred unidirectionally from the central area of ​​the atomizing section 320 to the peripheral areas. Due to the time difference in the heat transfer process, the atomizing medium 321 in the central area of ​​the atomizing section 320 heats up faster than the atomizing medium 321 in the peripheral areas, causing the atomizing medium 321 in the central area to reach the atomization temperature and atomize earlier than the atomizing medium 321 in the peripheral areas. In order to increase the atomization speed so that all the atomizing medium 321 in the atomizing section 320 reaches the atomization temperature simultaneously within a set short period of time, the heating temperature of the first sensing unit 100 must be increased. In this case, due to the limited heat transfer coefficient of the atomizing medium 321, the heat in the central area of ​​the atomizing section 320 cannot be quickly transferred to the peripheral areas in a short period of time. As a result, the atomizing medium 321 in the central area will be locally overheated and charred, which may cause the production of harmful substances and odorous substances, thereby affecting the user's puffing experience. At the same time, the edge region may experience a localized low temperature below the atomization temperature due to insufficient heat absorption, preventing the partial atomization medium 321 in the edge region from being fully atomized, thereby affecting the utilization rate of the atomized medium 321 and the entire atomized medium carrier 10. Similarly, if the atomized medium carrier 10 only has the second sensing unit 200 and only forms an edge heating mode, heat will be transferred unidirectionally from the edge region of the atomizing section 320 to the center region. In order to increase the atomization speed, the atomized medium 321 in the edge region will inevitably cause charring, which will also affect the user's puffing experience. In addition, the atomized medium 321 in the center region cannot be fully atomized, which affects the utilization rate of the atomized medium 321.

[0054] With respect to the atomizing medium carrier 10 in the above-described embodiment, the first sensing unit 100 and the second sensing unit 200 operate simultaneously to form a central heating mode and an edge heating mode, so that the atomizing medium 321 in both the central and edge regions of the atomizing section 320 can come into contact with the heat source. Heat can be transferred from the central region to the edge region, and from the edge region to the central region, so that heat can be transferred in both directions, thereby significantly reducing the time difference in the heat transfer process and ensuring that all atomizing media 321 in the atomizing section 320 can reach the atomizing temperature simultaneously in a short period of time, thereby increasing the atomization speed of the atomizing medium 321. At the same time, while ensuring a high atomization speed, not only is it not necessary to excessively increase the heating temperature of the first sensing unit 100 and the second sensing unit 200, but the heating temperature of the first sensing unit 100 and the second sensing unit 200 can be appropriately reduced to prevent the atomizing medium 321 from coking at excessively high temperatures, thereby improving the user experience. Furthermore, the atomized medium 321 in each location within the atomizing section 320 is heated evenly, ensuring that the atomized medium 321 in the center and edge areas reaches the atomizing temperature at the same time and is completely atomized, thereby ultimately improving the utilization rate of the atomized medium 321 and the entire atomized medium carrier 10 .

[0055] The present invention further provides an atomization system, which includes a heating atomization device 20 and the above-mentioned atomization medium carrier 10. The heating atomization device includes a temperature sensing unit, which is used to timely monitor the heating temperature of the second sensing unit 200.
