Specific embodiments

[0038] The application will be further described in details through specific embodiments combined with the drawings. In different embodiments, similar elements are associated with similar element labels. In the following embodiments, many details are described in order to make the application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials, methods. In some cases, some operations related to the application are not shown or described in the specification, in order to avoid the core part of the application being overwhelmed by too much description, and it is not necessary to describe these related operations in detail for those skilled in the art, they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0039] In addition, the features described in the specification, operations or characteristics can be combined in any appropriate manner to form various embodiments, and the steps involved in the operations of each embodiment can also be sequentially exchanged or adjusted in a manner apparent to those skilled in the art. Therefore, the description and drawings are only for the purpose of clearly describing one embodiment, and do not mean the necessary composition and / or order.

[0040] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.

[0041] The present application provides an atomization device 1, as shown in the figure, which can include a heating assembly 11 for heating an aerosol product 2 to atomize and generate an aerosol, and a temperature sensing assembly 12. The heating assembly 11 has a receiving cavity 11a, and a plug-in port 11b and a mounting port 11c communicating with the receiving cavity 11a. The aerosol product 2 can be inserted into the receiving cavity 11a through the plug-in port 11b. The temperature sensing assembly 12 is installed at the mounting port 11c. Wherein, an airflow passage 110 is formed between the aerosol product 2 and the heating assembly 11, and at least part of the temperature sensing assembly 12 passes through the mounting port 11c and is arranged on the airflow passage 110 to monitor the airflow temperature of the airflow passage 110. Figures 1 to 6

[0042] When the aerosol product 2 is inserted into the receiving cavity 11a and the atomization device 1 is used, because the airflow passage 110 is formed between the aerosol product 2 and the heating assembly 11, the airflow in the airflow passage 110 has a certain temperature. By arranging the temperature sensing assembly 12 on the airflow passage 110 of the atomization device 1, when external air flows into the airflow passage 110 during the use of the atomization device 1, the external air will lower the temperature of the temperature sensing assembly 12, so that the temperature sensing assembly 12 can timely monitor the temperature change of the airflow in the airflow passage 110. The signal of the temperature change can be used to control the heating temperature of the heating assembly 11. That is, as long as external air flows into the airflow passage 110, the external air will trigger the temperature sensing assembly 12 to work, which not only improves the sensitivity and accuracy of monitoring the heating temperature of the heating assembly 11, but also eliminates the dependence on the resistance value of the heating body in the prior art for temperature control by TCR value, so that the heating temperature of the heating assembly 11 to the aerosol product 2 can be more sensitive and accurate control to avoid the problem of burning the aerosol product 2.

[0043] ​The aerosol product 2 can be a rod-shaped structure, and the heating assembly 11 can form a cylindrical structure as a whole. The inner diameter of the cylindrical structure is greater than the outer diameter of the rod-shaped structure, so that when the aerosol product 2 is inserted into the accommodating cavity 11a, an airflow passage 110 can be formed between the aerosol product 2 and the heating assembly 11. The specific shape of the aerosol product 2 and the heating assembly 11 is not specially limited in the present application.

[0044] In some embodiments, as shown in Figure 2 and Figure 3 The heating assembly 11 can include a heating element 111 and an electromagnetic induction assembly 112. The accommodating cavity 11a, the insertion port 11b, and the mounting port 11c are arranged on the electromagnetic induction assembly 112, and the heating element 111 is located in the accommodating cavity 11a. The heating element 111 can generate heat when the electromagnetic induction assembly 112 is powered on, so as to heat the aerosol product 2.

[0045] The combination of the heating element 111 and the electromagnetic induction assembly 112 can form an electromagnetic heating structure, so that the atomization device 1 can input a high-frequency alternating current power to the electromagnetic induction assembly 112 to generate an alternating magnetic field. The alternating magnetic field can induce an eddy current inside the heating element 111, so that the heating element 111 generates heat and heats the aerosol product 2 to generate an aerosol. By changing the frequency of the alternating current power, the frequency and intensity of the alternating magnetic field can be adjusted, so that the heating speed of the heating element 111 can be adjusted, and the heating temperature of the heating element 111 to the aerosol product 2 can be more sensitive and accurate. The heating element 111 can be a sheet, a column, or a cylinder, and the specific shape of the heating element 111 is not specially limited in the present application.

[0046] In other embodiments, the heating assembly 11 can also be connected to the heating element 111 by a wire to form a resistance heating structure, so that the atomization device 1 can supply power to the heating element 111 through the wire. The heating element 111 generates heat after being powered on, and heats the aerosol product 2. The specific structure of the heating assembly 11 is not specially limited in the present application.

[0047] In some embodiments, as shown in Figures 3 to 6 The electromagnetic induction assembly 112 can include a heating container 1121 and an induction coil 1122. The insertion port 11b is arranged at the top of the heating container 1121, the mounting port 11c is arranged at the bottom of the heating container 1121, the accommodating cavity 11a is arranged in the heating container 1121, the induction coil 1122 is arranged on the side wall of the heating container 1121, and the heating element 111 is located in the induction coil 1122.

[0048] The induction coil 1122 can be wound in a spiral or serpentine shape on the outer wall surface of the heating container 1121, or it can be wound on the inner wall surface or inside the side wall of the heating container 1121. The heating container 1121 can be configured as a cylindrical structure with an opening at the top to form an insertion port 11b and an opening at the bottom to form a mounting port 11c. This application does not impose any special limitations on the shape or specific location of the induction coil 1122 or the specific shape of the heating container 1121.

[0049] The heating container 1121 can be made of insulating materials such as plastic, asbestos, or fiberglass to keep the container warm and prevent heat loss from the cavity 11a. The induction coil 1122 can be made of conductive metallic materials such as copper, aluminum, or alloys. This application does not impose any special restrictions on the specific materials of the heating container 1121 and the induction coil 1122.

[0050] In some embodiments, such as Figures 2 to 5 As shown, the heating assembly 11 may also include a shield 113; the shield 113 may be connected to the heating container 1121, and the shield 113 is sleeved on the outer wall of the heating container 1121, and the induction coil 1122 is disposed inside the shield 113.

[0051] The shield 113 prevents the alternating magnetic field signal generated by the induction coil 1122 from being lost due to outward radiation, thereby improving the heating efficiency of the heating element 111. The shield 113 can be configured as a cylindrical structure sleeved on the outside of the induction coil 1122, and the top of the shield 113 can be connected to the top of the heating container 1121.

[0052] In some embodiments, such as Figures 5 to 7 As shown, the temperature sensing component 12 may include a heat-conducting element 121 and a temperature sensor 122; at least a portion of the heat-conducting element 121 passes through the mounting port 11c and is disposed at the bottom of the receiving cavity 11a, and the temperature sensor 122 is disposed on the side of the heat-conducting element 121 away from the heating component 11, and the temperature sensor 122 is in contact with the heat-conducting element 121.

[0053] For example, the heat-conducting element 121 can be configured as a bowl-shaped structure. The protruding portion of the heat-conducting element 121 can pass through the mounting port 11c and be disposed at the bottom of the receiving cavity 11a, while the recessed portion of the heat-conducting element 121 can be used to house the probe of the temperature sensor 122, ensuring that the probe of the temperature sensor 122 is in contact with the heat-conducting element 121. When external air flows into the receiving cavity 11a along the airflow channel 110, the external air blows against the protruding portion of the heat-conducting element 121, causing the heat-conducting element 121 to cool down. The temperature drop of the heat-conducting element 121 transmits the temperature change signal to the temperature sensor 122, thereby enabling the temperature sensor 122 to sensitively detect changes in the airflow temperature within the airflow channel 110. The heat-conducting element 121 can be made of a metal material with high thermal conductivity, such as copper, aluminum, or alloys, or it can be made of a non-metallic thermally conductive material such as graphene or silicon carbide. This application does not impose any special restrictions on the specific material of the heat-conducting element 121.

[0054] Furthermore, the temperature sensor 122 is located on the side of the heat-conducting element 121 away from the heating assembly 11, which allows the temperature sensor 122 to be separated from the heating assembly 11. This avoids the problem of the temperature sensor 122 malfunctioning due to excessively high operating temperature of the heating assembly 11, thus extending the service life of the temperature sensor 122. When the airflow channel 110 is far away from the heating assembly 111, the temperature sensor 122 can also be directly installed in the airflow channel 110, in which case the heat-conducting element 121 is not required.

[0055] In other embodiments, the heat-conducting element 121 may also be configured as a rectangular protrusion. When the heat-conducting element 121 is inserted into the mounting port 11c, the top of the heat-conducting element 121 may be flush with the bottom of the receiving cavity 11a, thereby reducing the obstruction of airflow by the heat-conducting element 121. This application does not impose any special limitations on the specific shape of the heat-conducting element 121.

[0056] In some embodiments, such as Figure 3 As shown, the airflow channel 110 may include a connected sidewall airway 110a and a bottom airway 110b; the sidewall airway 110a is formed between the sidewall of the aerosol product 2 and the heating component 11, and the bottom airway 110b is formed between the bottom of the aerosol product 2 and the heating component 11. External air flows into the bottom airway 110b through the sidewall airway 110a, and the portion of the heat-conducting member 121 located in the receiving cavity 11a is in contact with the airflow flowing into the bottom airway 110b.

[0057] When the external air flows into the airflow channel 110, the external air flows vertically along the side wall air duct 110a to the bottom of the aerosol generating article 2, and then flows horizontally along the bottom air duct 110b to the center of the bottom of the aerosol generating article 2. When the external air blows against the heat conduction member 121, the temperature of the heat conduction member 121 decreases and transmits the signal of the temperature change to the temperature sensor 122. The side wall air duct 110a and the bottom air duct 110b can be linear air ducts or curved air ducts. When the airflow channel 110 is provided as a curved air duct, the time for the external air to stay in the airflow channel 110 can be increased, so that the heating container 1121 can preheat the external air flowing in, thereby improving the heating efficiency of the aerosol generating article 2. In other embodiments, the heat conduction member 121 can also be arranged in the side wall air duct 110a, and the specific position of the heat conduction member 121 is not specially limited in the present application.

[0058] In some embodiments, as shown in Figure 5 The atomization device 1 can further include a control assembly 13 and a power supply assembly 14. The control assembly 13 is electrically connected to the heating assembly 11 and the temperature sensing assembly 12, respectively. The power supply assembly 14 is electrically connected to the control assembly 13. The control assembly 13 controls the heating temperature of the heating assembly 11 according to the airflow temperature monitored by the temperature sensing assembly 12.

[0059] In this way, after receiving the signal of the temperature change of the airflow in the airflow channel 110, the temperature sensor 122 can transmit the signal of the temperature change to the control assembly 13 for data processing to generate a corresponding control signal. The control assembly 13 controls the frequency and strength of the alternating magnetic field generated by the electromagnetic induction assembly 112 according to the control signal, so as to accurately and sensitively control the temperature of the aerosol generating article 2 heated by the heating assembly 11, thereby avoiding the problem of burning of the aerosol generating article 2 and allowing the user to obtain a good taste of the aerosol generating article 2.

[0060] In some embodiments, as shown in Figure 5 The atomization device 1 can further include a support 15. The control assembly 13 can include a first circuit board 132 and a controller 131 electrically connected. The support 15 can be connected to the first circuit board 132. The heating assembly 11 is installed on the support 15. The first circuit board 132 can be electrically connected to the power supply assembly 14.

[0061] Thus, the heating assembly 11 can be mounted in the bracket 15, which can support the heating assembly 11. For example, the bracket 15 can be provided in a structure of an upper cylindrical shape and a lower box shape, so that the heating assembly 11 can be mounted in the upper cylindrical structure. The lower box structure can be connected to the first circuit board 132 by buckling or screwing, and the lead wires of the induction coil 1122 and the temperature sensor 122 can be electrically connected to the first circuit board 132, and the lead wires of the induction coil 1122 and the temperature sensor 122 can be wired in the lower box structure to avoid the problem of short circuit. The specific shape of the bracket 15 is not specially limited in the present application.

[0062] The controller 131 can be a microcontroller unit (MCU). The power supply assembly 14 can include a battery 141 and a second circuit board 142 electrically connected, and the first circuit board 132 can be electrically connected to the second circuit board 142, so that the battery 141 can supply power to the heating assembly 11 and the temperature sensing assembly 12 through the first circuit board 132 and the second circuit board 142. The specific structure of the control assembly 13 and the power supply assembly 14 is not specially limited in the present application.

[0063] In addition, in order to control the heating temperature of the heating assembly 11, the temperature sensor 122 can also be electrically connected to the display screen, so that the user can independently control the heating power of the heating assembly 11 according to the temperature data displayed on the display screen. For example, when the user needs to atomize a large amount of fog, the heating power of the heating assembly 11 can be adjusted through the adjustment switch, button and other structures on the atomization device 1 to meet the user's use demand. The specific control method of the atomization device 1 to control the heating assembly 11 is not specially limited in the present application.

[0064] In some embodiments, as shown in Figures 2 to 5 The atomization device 1 can also include a housing 16, the heating assembly 11, the temperature sensing assembly 12, the control assembly 13 and the power supply assembly 14 are all mounted in the housing 16, and the housing 16 is provided with a through hole 163 in communication with the insertion port 11b, so that the aerosol product 2 is inserted into the accommodation cavity 11a through the through hole 163.

[0065] For example, the housing 16 may include a first housing 161 and a second housing 162, which can be detachably connected by snap-fit, screw-fit, or plug-in. A through-hole 163 can be provided on the first housing 161. After the heating assembly 11, temperature sensing assembly 12, control assembly 13, and power supply assembly 14 are installed on the first housing 161, the insertion port 11b on the heating assembly 11 can be aligned with the through-hole 163 on the first housing 161. After installation, the second housing 162 is detachably connected to the bottom of the first housing 161, thus completing the assembly of the entire atomizing device 1. This application does not impose any special limitations on the specific structure of the housing 16.

[0066] In the above embodiments, the atomizing device 1 can be a heat-not-burning (HNB) appliance. The heating element 111 can be disposed at the bottom of the inner cavity 11a of the heating container 1121, and the temperature sensing component 12 can be disposed within the airflow channel 110, offset from the heating element 111, to avoid the temperature sensing component 12 being affected by the high temperature of the heating element 111 and to extend the service life of the temperature sensing component 12. Alternatively, the atomizing device 1 can also be an electronic atomizing device that heats the aerosol matrix through a heating mesh. The temperature sensing component 12 can also be disposed within the airflow channel 110 to sense changes in the airflow temperature within the airflow channel 110. When using the atomizing device 1, activating the atomizing device 1 heats the aerosol product 2, and the temperature sensing component 12 can sensitively and accurately sense temperature changes within the airflow channel 110, thereby allowing for more sensitive and accurate control of the heating temperature of the heating element 11. This application does not impose any special limitations on the structural form of the atomizing device 1.

[0067] In other embodiments, when the heating assembly 11 adopts an electromagnetic heating structure, the heating element 111 and the electromagnetic induction assembly 112 can also be configured as separate structures. For example, as Figures 2 to 5 As shown, the heating element 111 can also be installed inside the aerosol product 2. In this case, the aerosol product 2 and the atomizing device 1 can be combined to form an atomizing assembly, allowing the user to automatically start and stop the heating of the atomizing device 1 by inserting and removing the aerosol product 2.

[0068] Specifically, when the aerosol product 2 is inserted into the accommodating cavity 11a, the induction coil 1122 induces the heating element 111 in the aerosol product 2, and the magnetic field signal in the heating container 1121 changes, triggering the start signal to be transmitted to the control assembly 13, and the control assembly 13 starts heating the atomization device 1, so that the heating element 111 is heated and the aerosol product 2 is heated. At the same time, the temperature sensing assembly 12 monitors the temperature change of the airflow in the airflow channel 110 in real time. When the user uses the atomization device 1, the external air flows along the airflow channel 110 and blows the heat conduction element 121, and the temperature sensor 122 transmits the temperature change signal of the heat conduction element 121 to the control assembly 13 for PID processing, generates a corresponding PWM signal, and the control assembly 13 accurately calculates the alternating magnetic field of the induction coil 1122 according to the generated PWM signal, and controls the alternating frequency and strength of the magnetic field generated by the induction coil 1122, so as to accurately control the heating temperature of the heating element 111.

[0069] Therefore, by arranging the temperature sensing assembly 12 on the airflow channel 110 of the heating assembly 11, the application also realizes the function that the heating temperature of the heating assembly 11 can be monitored when the atomization device 1 adopts the structure of electromagnetic heating. At the same time, the temperature change signal monitored by the temperature sensing assembly 12 can be used to control the heating temperature of the heating assembly 11. Compared with the temperature control mode of the prior art, the application is free from the dependence of the heating assembly 11 on the prevention of the heating body, so that the temperature control of the atomization device 1 on the heating assembly 11 is more sensitive and accurate, thereby avoiding the problem that the aerosol product 2 is burnt.

[0070] The above application of specific examples to the utility model is described, which is only used to help understand the utility model, and does not limit the utility model. For the skilled in the art to which the utility model belongs, according to the idea of the utility model, a number of simple deductions, deformations or substitutions can be made.
