[0036] The present application provides an aerosol generating device 10 for heating an aerosol generating article, including a housing 1, a heating assembly 2 and an ultrasonic refrigeration module 3. The heating assembly 2 is disposed in the housing, the ultrasonic refrigeration module 3 is disposed in the housing 1, and the ultrasonic refrigeration module 3 is spaced apart from the heating assembly 2. The ultrasonic refrigeration module 3 is used for dissipating heat from the housing 1.

[0037] The aerosol generating device 10 provided by the present application includes an ultrasonic refrigeration module 3. After the ultrasonic refrigeration module 3 is powered on and vibrates, the air in the housing 1 flows, so that the temperature of the housing 1 of the aerosol generating device 10 is reduced.

[0038] In one embodiment of the present application, the ultrasonic refrigeration module 3 includes two ultrasonic refrigeration modules 31, and each ultrasonic refrigeration module 31 includes a piezoelectric member 311 and a deformation sheet 312 that are electrically connected to each other. The piezoelectric member 311 is disposed on the surface of the deformation sheet 312, and when the piezoelectric member 311 deforms, it drives the deformation sheet 312 to deform; the two deformation sheets 312 are stacked, and a gap is formed between the two deformation sheets 312. When the deformation sheet 312 deforms, it drives the air flow in the gap. The piezoelectric member 311 is an information functional material that can convert mechanical energy and electrical energy into each other. When the frequency of the electrical signal is close to the natural frequency of the piezoelectric sheet 311, the piezoelectric sheet 311 generates mechanical resonance by the inverse piezoelectric effect. When a first current is applied to the piezoelectric member 311, the deformation sheet 312 deforms in a first deformation mode, and the first deformation mode includes bending, bulging, denting, etc.; when a second current is applied to the piezoelectric member 311, the deformation sheet 312 deforms in a second deformation mode, and the second deformation mode includes bending, bulging, denting, etc. When the current supplied to the piezoelectric member 311 changes alternately between the first current and the second current, the deformation sheet 312 deforms alternately in the first deformation mode and the second deformation mode, and the deformation degree of the deformation sheet 312 changes alternately, forming vibrations. At this time, the air around the deformation sheet 312 is disturbed by the deformation sheet 312 to form an air flow and flows around the deformation sheet 312; it can be understood that the alternating deformation of the deformation sheet 312 can drive the air flow, and the air flow can accelerate the heat exchange of the air around the deformation sheet 312 to achieve the purpose of heat dissipation.

[0039] In one embodiment of the present application, the deformation directions of the two deformation sheets 312 include the opposite direction and the opposite direction, and the two deformation sheets 312 deform reciprocally in the opposite direction and the opposite direction. The deformation sheet 312 can vibrate at a high frequency, and the vibration frequency can reach the frequency of ultrasonic waves, thereby reducing the vibration noise and achieving silent heat dissipation. When the two deformation sheets 312 deform in the opposite direction, the volume of the gap increases, having an air suction effect; when the two deformation sheets 312 deform in the opposite direction, the volume of the gap decreases, and the air is squeezed out of the gap to form an air flow, and the air flow is discharged from the gap to achieve an exhaust effect; when the two deformation sheets 312 continuously reciprocate between deforming in the opposite direction and deforming in the opposite direction, the air flow is continuously squeezed out of the gap to form a heat dissipation air flow. Compared with the heat dissipation air flow formed by a fan, the air flow disturbance of this heat dissipation air flow is smaller and quieter.

[0040] In one embodiment of the present application, the current can be an alternating current, and the current directions of the first current and the second current are opposite. In one embodiment of the present application, the current can be a direct current, and the magnitudes of the first current and the second current are different. In one embodiment of the present application, the current is a pulsed current, and the magnitudes or directions of the first current and the second current are different.

[0041] In an embodiment of the present application, the piezoelectric component 311 includes a piezoelectric ceramic sheet and a piezoelectric quartz sheet. When the current in the piezoelectric ceramic sheet or the piezoelectric quartz sheet changes from a first current to a second current, the piezoelectric ceramic sheet and the piezoelectric quartz sheet can drive the deformation sheet 312 to change from a first deformation mode to a second deformation mode, so that the air around the deformation sheet 312 is disturbed, and thus the deformation sheet 312 can drive the air flow. The air flow can accelerate the heat exchange of the air around the deformation sheet, achieving the purpose of heat dissipation.

[0042] In an embodiment of the present application, the deformation sheet 312 includes a metal sheet. In an embodiment of the present application, the deformation sheet 312 is a structure that can be driven by the piezoelectric component 311 and has a certain flexibility. In an embodiment of the present application, the deformation sheet 312 is strip-shaped. During installation, the two ends of the deformation sheet 312 can be fixed, and the middle part of the deformation sheet 312 is suspended. The piezoelectric component 311 is arranged in the middle of the deformation sheet 312. In this way, when the piezoelectric component 311 deforms, the deformation sheet 312 can deform accordingly. When the suspended space where the deformation sheet 312 is located changes, air intake or exhaust can be achieved.

[0043] In an embodiment of the present application, at least two deformation sheets 312 are connected to each piezoelectric component 311. One piezoelectric component 311 can drive two deformation sheets 312 to deform respectively. In an embodiment of the present application, multiple deformation sheets 312 are connected to each piezoelectric component 311, and one piezoelectric component 311 can drive multiple deformation sheets 312 to deform respectively. In an embodiment of the present application, the piezoelectric component 311 is located in the middle of the deformation sheet 312, and the piezoelectric component 311 can drive the two ends of the deformation sheet 312 to vibrate.

[0044] In one embodiment of the present application, the ultrasonic refrigeration module 3 includes at least two ultrasonic refrigeration modules 31. There are at least two ultrasonic refrigeration modules 31, one of which is passed through by a first current and the other is passed through by a second current, and the magnitudes or directions of the first current and the second current are different. One of the two ultrasonic refrigeration modules 31 is passed through by the first current and the other is passed through by the second current, so that the deformation sheet 312 of one of the two ultrasonic refrigeration modules 31 deforms according to a first deformation mode, and the deformation sheet 312 of the other deforms according to a second deformation mode. The magnitudes or directions of the deformations of the two deformation sheets 312 are different, causing the air between the two deformation sheets 312 to be disturbed, thereby driving the air flow between the two deformation sheets 312. The air flow can accelerate the heat exchange of the air around the deformation sheet, achieving the purpose of heat dissipation. In one embodiment of the present application, the first current and the second current are in opposite directions, so that the deformation directions of the two deformation sheets 312 are opposite, and the air between the two deformation sheets 312 generates convection, making the air flow between the two ultrasonic refrigeration modules 31 more intense and accelerating the heat exchange between the two ultrasonic refrigeration modules 31. In one embodiment of the present application, the ultrasonic refrigeration modules 31 are arranged in an array. For example, the ultrasonic refrigeration modules 31 are arranged in a 2*4 array. In one embodiment of the present application, the ultrasonic refrigeration module 3 includes at least two ultrasonic refrigeration modules 31, and there are multiple ultrasonic refrigeration modules 3. The multiple ultrasonic refrigeration modules 3 are arranged in an array.

[0045] In one embodiment of the present application, air holes 32 are provided between any two adjacent ultrasonic refrigeration modules 3. The air holes 32 provide space for the air flow in the ultrasonic refrigeration module 3.

[0046] In one embodiment of the present application, the ultrasonic refrigeration module 3 includes a temperature sensor 33, and the temperature sensor 33 is configured to start the ultrasonic refrigeration module 3 after exceeding a preset temperature. In one embodiment of the present application, the preset temperature can be set to 45°C. When the temperature of the housing 1 exceeds 45°C, the ultrasonic refrigeration module 31 is started, causing the air inside the housing 1 to flow, thereby reducing the surface temperature of the housing 1. In one embodiment of the present application, the temperature sensor 33 is located at the position where the temperature of the housing 1 is the highest, and the temperature sensor 33 can also adjust the working power of the ultrasonic refrigeration module 31 according to the change in the temperature of the housing 1.

[0047] In one embodiment of the present application, the ultrasonic refrigeration module 3 is attached to the inner wall of the housing 1. On the one hand, it can detect the temperature of the housing 1, and on the other hand, it can also ensure the beauty of the appearance of the housing 1.

[0048] In one embodiment of the present application, the housing 1 defines a gas chamber 11. The gas chamber 11 has a first opening 111, and the first opening 111 is located on one side of the housing 1 close to the insertion direction of the aerosol generating article. One end of the gas chamber 11 is open, so that the air outside the housing 1 can enter the gas chamber 11 through the first opening 111, enabling the gas in the gas chamber 11 to exchange with the outside gas and facilitating heat dissipation of the housing 1.

[0049] In one embodiment of the present application, the housing 1 defines a gas chamber 11, and the gas chamber 11 further has a second opening 112, and the second opening 112 is located on the side wall of the housing 1. In one embodiment of the present application, one end of the gas chamber 11 is open, and the opening is located on the side wall of the housing 1. In one embodiment of the present application, the gas chamber 11 has both a first opening 111 and a second opening 112, making the air exchange between the gas chamber 11 and the outside air more intense and accelerating the heat dissipation of the housing 1.

[0050] In one embodiment of the present application, the housing 1 defines a receiving chamber 12 for inserting the aerosol generating article. The gas chamber 11 and the receiving chamber 12 are spaced apart, and the gas between the gas chamber 11 and the receiving chamber 12 is isolated, so that most of the heat in the receiving chamber 12 is retained in the receiving chamber 12 to heat the aerosol generating article.

[0051] In one embodiment of the present application, a heat insulation component 13 is provided on the outer side wall of the receiving chamber 12. The heat insulation component 13 retains most of the heat in the receiving chamber 12 to heat the aerosol generating article and prevents heat from being transferred to the surface of the housing 1. In one embodiment of the present application, the ultrasonic refrigeration module 3 is disposed on the side of the gas chamber 11 close to the receiving chamber 12 to facilitate heat diffusion in the gas chamber 11. In one embodiment of the present application, the heat insulation component 13 includes a heat insulating material, and the heat insulating material refers to a material with a thermal conductivity less than 100 W / m·K at 23°C and 50% relative humidity, preferably less than 40 W / m·K or less than 10 W / m·K. For example, the heat insulating material can be made of at least one of PAEK-based materials, PI materials or PBI materials, where PAEK-based materials include PEEK, PEKK, PEKEKK or PEK materials; the heat insulating material can also include aerogel.

[0052] In one embodiment of the present application, the heat insulation component 13 includes a heat storage material, which refers to a material with a high heat capacity. The material with a high heat capacity can be a material with a specific heat capacity of at least 0.5 J / g.K at 25°C and constant pressure. For example, the material with a high heat capacity can be a material with a specific heat capacity greater than or equal to 0.7 J / g.K at 25°C and constant pressure; again, the material with a high heat capacity can be a material with a specific heat capacity greater than or equal to 0.8 J / g.K at 25°C and constant pressure. In some examples, the heat storage material may include, but is not limited to, glass fiber, glass felt, ceramics, silica, alumina, carbon, and ore, or any combination thereof. In one embodiment of the present application, the heat insulation component 13 may further include a vacuum tube. The air pressure inside the vacuum tube is low, and the gas fluidity is poor, so that the heat exchange on both sides of the vacuum tube is less.

[0053] In one embodiment of the present application, the aerosol generating device 10 is a device with a circumferential heating function or a central heating function. In one embodiment of the aerosol generating device 10 with central heating in the present application, the aerosol generating device 10 includes a central heating needle, and the central heating needle extends into the receiving cavity 12. When the aerosol generating article is inserted into the receiving cavity 12, the central heating needle is inserted into the aerosol generating article. In one embodiment of the aerosol generating device 10 with circumferential heating in the present application, the aerosol generating device 10 includes a heating tube, and the heating tube is arranged around the receiving cavity 12, and the heating tube generates heat through resistance heating or under the action of electromagnetic force.

[0054] In one embodiment of the present application, the aerosol generating device 10 further includes a battery assembly 4, and the battery assembly supplies electrical energy to the heating assembly 2 and the ultrasonic refrigeration module 3.

[0055] When simulating the heating of the aerosol generating article, the temperature distribution of the aerosol generating device 10 is as Figures 3 - 5 shown, where Figure 3 and Figure 5 are the temperature simulation diagrams of the aerosol generating device 10 after setting the ultrasonic refrigeration module, Figure 4 is the temperature simulation diagram of the aerosol generating device 10 without setting the ultrasonic refrigeration module, Figure 4 the highest temperature on the surface of the aerosol generating device 10 is 51°C, Figure 5 the highest temperature on the surface of the aerosol generating device 10 is 47°C. It can be seen that after the aerosol generating device 10 is provided with the ultrasonic refrigeration module 3, the temperature on the surface of the housing 1 of the aerosol generating device 10 is significantly reduced.

[0056] It should be noted that the description and drawings of this application provide preferred embodiments of this application, but are not limited to the embodiments described in this specification. Further, for those of ordinary skill in the art, improvements or transformations can be made based on the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of this application.
