Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically to an aerosol generation apparatus. Background Technology

[0002] The aerosol generating device (hereinafter referred to as the "generating device") includes a heating module and a power supply module. The power supply module supplies power to the heating module, which, after being powered on, heats the aerosol generating matrix, enabling it to produce volatile substances such as aerosols without combustion. To improve the applicability and service life of the generating device, the heating module and power supply module can be designed as detachable structures. However, because the heating module generates a large amount of heat during operation, when the heating module is removed for internal maintenance or parts replacement, the accumulated heat can cause the overall or localized temperature of the heating module to become excessively high, potentially resulting in burns to the operator.

[0031] Please see Figures 1 to 5 The generating device includes a heating module 100, a power supply module 200, a magnetic connection assembly 300, and an adjustment assembly. The heating module 100 includes a housing 110 and a heating element 120, which is detachably disposed within the housing 110. The power supply module 200 supplies power to the heating module 100, and the power supply module 200 and the heating module 100 are detachably connected. The magnetic connection assembly 300 is disposed between the heating element 120 and the housing 110, and / or between the heating module 100 and the power supply module 200. The adjustment assembly is used to adjust the magnetic attraction force of the magnetic connection assembly 300 according to the temperature of the heating module 100, so as to adjust the bonding force between the heating element 120 and the housing 110, and / or the bonding force between the heating module 100 and the power supply module 200.

[0032] The heating element 120, acting as a heat source, heats the aerosol to generate matrix A after being powered on. The outer casing 110, serving as the overall structural form of the heating module 100, can be an assembly consisting of at least one component. The outer casing 110 houses the heating element 120, facilitating integrated carrying and installation of the heating module 100. Furthermore, the detachable connection between the heating element 120 and the outer casing 110 allows for individual disassembly of the heating element 120 for maintenance or replacement. The power supply module 200 provides power to the entire generating device, supplying power to the heating module 100 while simultaneously controlling and adjusting its operating status. The detachable connection between the power supply module 200 and the heating module 100 also facilitates individual disassembly of both modules.

[0033] In this application, the magnetic connection component 300 is disposed between the heating component 120 and the outer casing 110 and / or between the heating module 100 and the power supply module 200. Firstly, the magnetic connection component 300, disposed between the heating component 120 and the outer casing 110, allows for a detachable connection between the heating component 120 and the outer casing 110 via magnetic force. The heating module 100 and the power supply module 200 can be connected via detachable methods such as threaded connection, snap-fit, or plug-in connection. Secondly, the magnetic connection component 300, disposed between the heating module 100 and the power supply module 200, allows for a detachable connection between the heating module 100 and the power supply module 200 via magnetic force. The heating component 120 and the outer casing 110 can be connected via detachable methods such as threaded connection, snap-fit, or plug-in connection. Thirdly, the magnetic connection component 300 can be understood as being positioned between the heating module 100 and the power supply module 200, and also between the heating element 120 and the outer casing 110. This allows the heating module 100 and the power supply module 200 to be detachably connected via magnetic force, and the heating element 120 and the outer casing 110 to be detachably connected via magnetic force as well. The magnetic connection component 300 only needs to ensure that the outer casing 110 and the heating element 120 cannot be separated at higher temperatures.

[0034] The magnetic connection component 300 and the adjustment component work together to adjust the bonding force, thereby making the two parts locked together or easy to separate. Specifically, when the magnetic attraction force is small, the bonding force between the two parts is small and easy to separate. When the magnetic attraction force is large, the bonding force between the two parts is large, the two parts are locked together, and it is not easy to separate the two parts by human force.

[0035] After using the generating device, if the user wants to remove the heating component 120 for cleaning or replacement, the heating module 100 and the power supply module 200 need to be separated first, and then the heating component 120 and the outer casing 110 need to be separated. Through the setting of the magnetic connection component 300 and the adjustment component, when the temperature of the heating module 100 is too high, the magnetic attraction of the magnetic connection component 300 increases, which increases the bonding force between the heating component 120 with the magnetic connection component 300 and the outer casing 110 and / or between the heating module 100 and the power supply module 200. The user cannot separate the heating component 120 from the outer casing 110 and / or the heating module 100 from the power supply module 200, thus avoiding the user from being burned by direct contact with the high-temperature heating module 100.

[0036] The power supply module 200 includes a battery and a second control board that are electrically connected to each other. The second control board can control the working status of the entire generating device (including start-up and shutdown), and can also control and adjust the working temperature (or power) of the heating module 100.

[0037] In some embodiments, at least two magnetic connection components 300 are provided, wherein at least one magnetic connection component 300 is disposed between the housing 110 and the heating component 120, and at least another magnetic connection component 300 is disposed between the heating module 100 and the power supply module 200. For example, four magnetic connection components 300 are provided, wherein two magnetic connection components 300 are disposed between the heating module 100 and the power supply module 200, and the two magnetic connection components 300 are symmetrically arranged along the central axis of the heating module 100 and the power supply module 200, and the remaining two are disposed between the housing 110 and the heating component 120, and are symmetrically arranged along the central axis of the housing 110 and the heating component 120.

[0038] In some embodiments, the magnetic connection assembly 300 includes a first magnetic element 310 and a second magnetic element 320 correspondingly disposed, and the first magnetic element 310 and the second magnetic element 320 are magnetically connected. When the magnetic connection assembly 300 is disposed between the heating module 100 and the power supply module 200, the first magnetic element 310 and the second magnetic element 320 are respectively disposed on the heating module 100 and the power supply module 200, that is, disposed on the outer casing 110 and the power supply module 200. When the magnetic connection assembly 300 is disposed between the outer casing 110 and the heating component 120, the first magnetic element 310 and the second magnetic element 320 are respectively disposed on the outer casing 110 and the heating component 120. When the magnetic connection assembly 300 is disposed between the heating module 100 and the power supply module 200, and also between the heating component 120 and the outer shell 110, the heating module 100 and the power supply module 200 are respectively equipped with the first magnetic attraction element 310 and the second magnetic attraction element 320, and the heating component 120 and the outer shell 110 are also respectively equipped with the first magnetic attraction element 310 and the second magnetic attraction element 320.

[0039] In some embodiments, the magnetic connection assembly 300 is any one or a combination of a solenoid coil and an electromagnet, that is, the first magnetic element 310 and the second magnetic element 320 can be any one or a combination of a solenoid coil and an electromagnet. Both the first magnetic element 310 and the second magnetic element 320 can be electromagnets. The first magnetic element 310 and the second magnetic element 320 have different magnetic poles after being energized, and the connection is achieved by utilizing the principle of opposite poles attracting each other. One of the first magnetic element 310 and the second magnetic element 320 can be a solenoid coil, and the other can be either a solenoid coil or an electromagnet. After being energized, the solenoid coil generates a magnetic field that attracts the solenoid coil or the electromagnet to achieve the connection between the heating module 100 and the power supply module 200 and / or the outer casing 110 and the heating component 120.

[0040] In other embodiments, one of the first magnetic element 310 and the second magnetic element 320 can be any one or a combination of a solenoid coil and an electromagnet, and the other is a metal part (e.g., an iron product). After being energized, the heating module 100 is connected to the power supply module 200 and / or the outer casing 110 is connected to the heating component 120 by using the magnetic attraction principle.

[0041] In some embodiments, the adjustment component includes a temperature sensor, a first control board 400, and a drive mechanism. The temperature sensor, the first control board 400, and the drive mechanism are electrically connected. The temperature sensor is disposed inside the housing 110 and is used to acquire the temperature of the heating module 100. The first control board 400 is used to control the drive mechanism to start or stop according to the temperature of the heating module 100. The output end of the drive mechanism is connected to the first magnetic element 310 and / or the second magnetic element 320 and is used to drive the first magnetic element 310 and / or the second magnetic element 320 to move according to the temperature detected by the temperature sensor, so as to adjust the magnetic attraction between the first magnetic element 310 and the second magnetic element 320. Specifically, when the temperature sensor detects that the temperature of the heating component 120 is too high, the drive mechanism may remain inactive or activate to drive the first magnetic element 310 and the second magnetic element 320 closer together, thereby reducing the distance between them and increasing the magnetic attraction between them. This increases the bonding force, making it difficult for the user to separate the heating module 100 from the power supply module 200 and / or the housing 110 from the heating component 120. When the temperature sensor detects that the temperature of the heating component 120 is low (e.g., below 50°C), the drive mechanism activates to drive the first magnetic element 310 and the second magnetic element 320 further apart, increasing the distance between them and weakening the magnetic attraction between them. This reduces the bonding force, allowing the user to easily separate the heating module 100 from the power supply module 200 and / or the housing 110 from the heating component 120.

[0042] In some embodiments, the drive mechanism can be a linear motor or a piston cylinder, which can directly perform linear motion. The drive mechanism can also be a combination of a rotary motor and a lead screw, which can convert the rotational motion of the rotary motor into linear motion, thereby driving the first magnetic element 310 and the second magnetic element 320 to move away from or closer to each other.

[0043] In some embodiments, the number of drive mechanisms can be the same as the total number of first magnetic elements 310 and second magnetic elements 320, so that each first magnetic element 310 is configured with a drive mechanism and each second magnetic element 320 is also configured with a drive mechanism, thereby realizing individual control of the first magnetic element 310 and the second magnetic element 320.

[0044] In some embodiments, the adjustment assembly includes a temperature sensor and a first control board 400 electrically connected to each other. The temperature sensor is disposed within the housing 110 and is used to acquire the temperature of the heating module 100. The first control board 400 is electrically connected to the magnetic connection assembly 300 and is used to adjust the current applied to the magnetic connection assembly 300 according to the temperature of the heating module 100. The magnetic connection assembly 300 also includes connecting wires that are electrically connected to the first control board 400 and the power supply module 200. The temperature sensor transmits the acquired temperature of the heating module 100 to the first control board 400, and the first control board 400 controls and adjusts the current supplied by the power supply module 200 to the first magnetic attraction element 310 and / or the second magnetic attraction element 320 to adjust the magnetic attraction force and thus the bonding force. Specifically, when the current applied to the magnetic connection assembly 300 is increased, the magnetic attraction force increases and thus the bonding force increases, making it difficult for the user to separate the heating module 100 from the power supply module 200 and / or the housing 110 from the heating element 120. When the current applied to the magnetic connection assembly 300 is reduced, the magnetic attraction weakens and the bonding force decreases, allowing the user to easily separate the heating module 100 from the power supply module 200 and / or the housing 110 from the heating element 120.

[0045] In some embodiments, the regulating component includes a thermistor disposed within the housing 110 and electrically connected to the magnetic connection component 300. The thermistor adjusts the resistance in the circuit of the magnetic connection component 300 according to the temperature of the heating module 100, thereby regulating the current applied to the magnetic connection component 300. Due to the inherent characteristics of the thermistor, its resistance value can change with temperature, thus affecting the current in the circuit of the magnetic connection component 300. This allows for increased magnetic attraction at higher temperatures and decreased magnetic attraction at lower temperatures, thereby preventing burns to the user.

[0046] Please see Figure 2 In some embodiments, the outer shell 110 and the heating element 120 are provided with a first mounting groove 500 on their opposite sides, and the magnetic connection component 300 is embedded in the first mounting groove 500. The first mounting groove 500 facilitates the fixing of the magnetic connection component 300 and makes the contact surfaces of the outer shell 110 and the heating element 120 flush, reducing space occupation.

[0047] Please continue reading. Figure 2In some embodiments, a second mounting groove 600 is provided on the opposite sides of the housing 110 and the power supply module 200, and the magnetic connection component 300 is embedded in the second mounting groove 600. The second mounting groove 600 has the same function as the first mounting groove 500, and will not be described in detail here. In actual design, the first mounting groove 500 and the second mounting groove 600 are set according to the magnetic connection component 300. The number of first mounting grooves 500 is the sum of the number of first magnetic elements 310 and second magnetic elements 320 between the housing 110 and the heating component 120, and the number of second mounting grooves 600 is the sum of the number of first magnetic elements 310 and second magnetic elements 320 between the housing 110 and the power supply module 200.

[0048] Please see Figure 4 and Figure 5 In some embodiments, the heating component 120 includes an inner housing 121 and a heating element 122. The heating element 122 is electrically connected to the power supply module 200 and is used to heat the aerosol generating matrix A and / or the flowing airflow after being powered on, so as to heat the aerosol generating matrix A to form an aerosol by at least one of central heating, circumferential heating and airflow heating. The inner housing 121 is disposed outside the heating element 122 and inside the outer housing 110. An adjustment component is disposed on the inner housing 121. The inner housing 121 is made of an insulating material with low thermal conductivity. The low thermal conductivity can reduce the heat loss from the inner housing 121 and improve the heat utilization rate of the heating element 122. Since the adjustment component is disposed on the inner housing 121, the adjustment component may include a conductive structure (such as a thermistor). The circuit connection in contact with the inner housing 121 affects the adjustment of the magnetic attraction force of the magnetic connection component 300. The inner housing 121 should be made of an insulating material, such as polyetheretherketone (PEEK).
