This application provides a heating atomization device that can improve temperature control accuracy.

Referring to Figures 1, 2, 3 and 4, a heating atomization device 10 provided by an embodiment of the present application includes a host 100, a media carrier 200 and a temperature control body 300. The media carrier 200 is detachably connected to the host 100, and the temperature control body 300 can be accommodated in the media carrier 200.

The host 100 includes an outer conductor 110, an inner conductor 120 and a microwave unit 130. Both the outer conductor 110 and the inner conductor 120 are conductors with good electrical conductivity.

The outer conductor 110 may be a columnar structure such as a cylinder or a prism. The outer conductor 110 includes a bottom plate 112 and a side barrel 113 . The side tube 113 is arranged vertically and surrounds the central axis of the entire outer conductor 110 , the bottom plate 112 is arranged horizontally, and the side tube 113 is connected to the periphery of the bottom plate 112 . The side cylinder 113 and the bottom plate 112 together form a heating chamber 111 . The inner conductor 120 is located within the heating chamber 111 and can be inserted into the temperature control body 300 .

The inner conductor 120 includes a fixing part 121 and an insertion part 122. The lower end of the fixed part 121 is fixedly connected to the bottom plate 112 , and the lower end of the insertion part 122 is fixedly connected to the end of the fixed part 121 away from the bottom plate 112 , that is, the lower end of the insertion part 122 is connected to the upper end of the fixed part 121 , and the upper end of the insertion part 122 for the free end. The fixing part 121 is located outside the temperature control body 300, and the insertion part 122 is accommodated in the temperature control body 300 due to insertion. The cross-sectional area of the fixing part 121 may be larger than that of the inserting part 122 . When the entire media carrier 200 is loaded on the host 100, the bearing section 220 will be inserted into the heating chamber 111, so that the lower end of the bearing section 220 is in contact with the upper end of the fixing part 121, so the upper end of the fixing part 121 faces the entire media carrier. The assembly of 200 on the host 100 plays a very good limiting role.

The microwave unit 130 includes an antenna 131 and a microwave generator connected to each other. The microwave generator may be located outside the heating cavity 111 , and a part of the antenna 131 extends into the heating cavity 111 . The microwaves generated by the microwave generator are transmitted into the heating cavity 111 through the antenna 131 . When the host 100 is working, the microwave generator transmits microwaves into the heating cavity 111 through the antenna 131 .

In some embodiments, the media carrier 200 includes a nozzle section 210 and a carrying section 220, and the nozzle section 210 and the carrying section 220 are connected to each other.

The nozzle section 210 is at least partially located outside the heating chamber 111, and the user can contact the portion of the nozzle section 210 located outside the heating chamber 111 for suction.

The bearing section 220 is located within the heating chamber 111 . The carrying section 220 includes a wave-transmitting body 221, which can be made of non-metallic materials. The wave-transmitting body 221 surrounds a receiving cavity, and the atomized medium 20 is wrapped in the containing cavity by the wave-transmitting body 221. That is, the wave-transmitting body 221 is used to accommodate the atomized medium 20 . The wave-transmitting body 221 does not hinder the transmission of microwaves, that is, microwaves can pass through the wave-transmitting body 221 . When the microwaves generated by the microwave generator are transmitted into the heating cavity 111 , the microwaves in the heating cavity 111 will further enter the accommodation cavity through the wave-transmitting body 221 to be absorbed by the atomized medium 20 . The atomizing medium 20 will absorb the microwave and generate heat through the principle of microwave heating. Finally, the atomizing medium 20 will be atomized under the action of heat to form an aerosol that can be inhaled by the user.

In some embodiments, the temperature control body 300 has a receiving cavity 310. For example, the temperature control body 300 may be substantially a hollow columnar structure. The receiving cavity 310 is actually an open cavity, and the open opening of the receiving cavity 310 is disposed toward the bottom plate 112 of the outer conductor 110, that is, the open opening is disposed downward. The temperature control body 300 has a side wall surface 321 and a bottom wall surface 322. The side wall surface 321 and the bottom wall surface 322 jointly define the boundary of the receiving cavity 310. The bottom wall surface 322 is arranged horizontally, and the bottom wall surface 322 may be perpendicular to the central axis of the temperature control body 300 . The side wall surface 321 is an annular surface and is arranged vertically. The side wall surface 321 surrounds the central axis of the temperature control body 300 and is connected to the periphery of the bottom wall surface 322 . The fixed part 121 of the inner conductor 120 is located outside the receiving cavity 310. The insertion part 122 of the inner conductor 120 is received in the receiving cavity 310 due to the insertion. The upper end of the inner conductor 120 can be in contact with the bottom wall surface 322. The inner conductor 120 There is no mutual contact relationship with the side wall surface 321 , so that a certain distance is maintained between the inner conductor 120 and the side wall surface 321 . When both the temperature control body 300 and the insertion part 122 are cylindrical structures, the outer diameter of the temperature control body 300 may be about two times to about ten times the diameter of the insertion part 122 .

In some embodiments, for example, the temperature control body 300 is fixed in the bearing section 220 , the temperature control body 300 exists attached to the media carrier 200 , and the temperature control body 300 exists independently relative to the host 100 . The temperature control body 300 is inserted in the bearing section 220 so that the atomization medium 20 directly covers the temperature control body 300 . When the media carrier 200 is loaded into the host 100, the bearing section 220 is located in the heating cavity 111, and the bottom wall 322 of the temperature control body 300 and the upper end of the insertion portion 122 are in contact with each other; when the media carrier 200 is unloaded from the host 100 , the bearing section 220 is located outside the heating cavity 111, and the temperature control body 300 and the insertion part 122 are separated from each other.

Therefore, the temperature control body 300 has the first state and the second state. When the temperature control body 300 is in the first state, the temperature control body 300 will be located in the heating cavity 111 , and the bottom wall surface 322 of the temperature control body 300 is in contact with the free end of the insertion portion 122 to form a contact relationship. At this time, the inner conductor 120 is inserted into the temperature control body 300 . When the temperature control body 300 is in the second state, the bottom wall surface 322 of the temperature control body 300 will stop contacting the free end of the insertion portion 122, so that the temperature control body 300 is fixed on the bearing section 220 and separated from the entire inner conductor 120. That is, the temperature control body 300 follows the dielectric carrier 200 and leaves the inner conductor 120 .

In other embodiments, the temperature control body 300 can be directly fixed on the free end of the insertion part 122, that is, the bottom wall surface 322 of the temperature control body 300 is fixedly connected to the upper end of the insertion part 122 to form a contact relationship. The temperature control body 300 exists dependent on the host 100 , and the temperature control body 300 exists independently relative to the medium carrier 200 . When the media carrier 200 is loaded into the host 100, the bearing section 220 is located in the heating cavity 111, and the temperature control body 300 will be inserted into the bearing section 220; when the media carrier 200 is unloaded from the host 100, the bearing section 220 is located in the heating chamber 111. Outside the cavity 111 , the temperature control body 300 is still fixed on the insertion portion 122 of the inner conductor 120 . Therefore, the inner wall surface of the temperature control body 300 is always connected to the free end of the insertion portion 122 to form a contact relationship.

In some embodiments, the temperature control body 300 includes a base part and a temperature control part. The resistance of the base portion does not change with temperature. The resistance of the temperature control part changes with the temperature. For example, the temperature control part may be a thermistor. The temperature control part has a critical temperature. When it is greater than and exceeds the critical temperature, the resistance of the temperature control part changes suddenly from the initial range, thereby changing the initial conductivity; when it is less than or equal to but not exceeding the critical temperature, the resistance of the temperature control part returns to the initial range, thereby making the temperature control The initial conductivity is restored. The critical temperature of the temperature control part may range from about 100°C to about 400°C, and the specific value of the critical temperature may be about 100°C, about 250°C, about 300°C, or about 400°C, etc.

In some embodiments, the base part is made of non-metallic material, the base part is an insulator, the temperature control part has a layered structure, and the temperature control part will be attached to the inner surface and/or the inner surface of the base part. In other embodiments, the base part can be made of metal material, the base part is a conductor, and the temperature control part is connected to one end of the base part. In one embodiment, the temperature control body 300 only includes one temperature control part. In another embodiment, the temperature control body 300 includes multiple temperature control parts, so that the multiple temperature control parts are connected to each other to form the temperature control body 300. The critical temperatures of different temperature control parts may be different.

In some embodiments, the temperature control part may be a negative temperature coefficient thermistor, that is, an NTC (Negative Temperature Coefficient) thermistor. The resistance of the temperature control part decreases as the temperature increases. When the temperature of the temperature control part rises above the critical temperature, the resistance of the temperature control part will exponentially decrease by several orders of magnitude from the initial range. This can be understood as an avalanche of decline in the resistance of the temperature control part, causing the temperature to drop. The control part changes the initial conductivity. When the temperature of the temperature control part drops to be equal to or less than the critical temperature, the resistance of the temperature control part will quickly return to the initial range, so that the temperature control part returns to the initial conductivity. Generally, when the critical temperature is not exceeded, the resistance of the temperature control part is large and the conductivity is negligible, that is, the temperature control part is an insulator; when the critical temperature is exceeded, the resistance of the temperature control part is small, so that the temperature control part is made of an insulator. converted into a conductor.

In other embodiments, the temperature control part may be a positive temperature coefficient thermistor, that is, a PTC (Positive Temperature Coefficient) thermistor, and the resistance of the temperature control part increases as the temperature rises. When the temperature of the temperature control part rises above the critical temperature, the resistance of the temperature control part will increase exponentially from the initial range by several orders of magnitude. It can be understood vividly that the resistance of the temperature control part will rise in a rocket state, causing the temperature to rise. The control part changes the initial conductivity. When the temperature of the temperature control part drops to be equal to or less than the critical temperature, the resistance of the temperature control part will quickly return to the initial range, so that the temperature control part returns to the initial conductivity. Generally, when the critical temperature is not exceeded, the resistance of the temperature control part is small, that is, the temperature control part is a conductor; when the critical temperature is exceeded, the resistance of the temperature control part is large, so that the temperature control part is transformed from a conductor into an insulator.

When the bottom wall surface 322 of the temperature control body 300 is in contact with the upper end of the insertion part 122, the outer conductor 110, the inner conductor 120 and the temperature control body 300 can be coaxially arranged, so that the heating cavity 111 forms a resonant cavity. The length and cross-section of the outer conductor 110 , the inner conductor 120 and the temperature control part in a conductor state will form an influencing factor of the resonant frequency of the heating cavity 111 . When the resonant frequency of the heating cavity 111 does not match the microwave emission frequency, it can be understood that when the resonant frequency and the emission frequency are not equal, or the difference between the resonant frequency and the emission frequency is greater than the set range, the heating cavity 111 blocks or stops microwave transmission. , so that the microwaves generated by the microwave generator cannot enter the heating cavity 111, and thus the atomization medium 20 cannot absorb the microwaves and continue to generate heat. It can be generally understood that the host 100 cannot heat the atomization medium 20. When the resonant frequency of the heating cavity 111 matches the emission frequency of the microwave, it can be understood that when the resonant frequency is equal to the emission frequency, or the difference between the resonant frequency and the emission frequency is less than the set range, the heating cavity 111 allows microwave transmission, so that the microwave The microwaves generated by the generator enter the heating cavity 111 smoothly, thereby ensuring that the atomization medium 20 effectively absorbs the microwaves and generates heat. It can be generally understood that the host 100 can heat the atomization medium 20 . The emission frequency of the microwave generated by the microwave generator can be about 2450Mhz, and the wavelength of the microwave is about 122mm.

In the case where the temperature control part is an NTC thermistor, when the temperature of the temperature control part does not exceed the critical temperature, the temperature control part is an insulator, and the length of the temperature control part does not affect the resonant frequency of the heating cavity 111, that is, the length of the temperature control part It does not constitute an influencing factor of the resonant frequency of the heating cavity 111 , and the resonant frequency of the heating cavity 111 is only related to the inner conductor 120 and the outer conductor 110 . At this time, the resonant frequency of the heating cavity 111 is equal to the emission frequency of the microwave, and the resonant frequency will match the emission frequency. Therefore, the microwave can be transmitted in the heating cavity 111 and be absorbed by the atomization medium 20 , so that the host 100 is more sensitive to the atomization medium 20 heating. When the temperature of the temperature control part exceeds the critical temperature, the temperature control body 300 is converted from an insulator into a conductor. The length of the temperature control part will affect the resonant frequency of the heating cavity 111, that is, the length of the temperature control part constitutes an influencing factor of the resonant frequency of the heating cavity 111. Since the length and cross-section of the inner conductor 120 and the outer conductor 110 remain unchanged, the resonant frequency of the heating cavity 111 is simultaneously related to the inner conductor 120, the outer conductor 110 and the temperature control part. At this time, the resonant frequency of the heating cavity 111 will change, making the resonant frequency and the emission frequency not equal, resulting in the resonant frequency not matching the emission frequency, so the microwave cannot be transmitted in the heating cavity 111 to be absorbed by the atomized medium 20, so that The host computer 100 cannot heat the atomization medium 20 . Since the host computer 100 cannot heat the atomizing medium 20 , the temperatures of the atomizing medium 20 and the temperature control part will drop to no more than the critical temperature. At this time, the temperature control part will return to an insulator, thereby causing the resonant frequency of the heating cavity 111 to return to The state that is equal to the emission frequency of the microwave ensures that the host 100 heats the atomization medium 20 again.

In the case where the temperature control part is a PTC thermistor, when the temperature of the temperature control part does not exceed the critical temperature, the temperature control part is a conductor, and the length of the temperature control part affects the resonant frequency of the heating cavity 111, that is, the length of the temperature control part constitutes The influencing factor of the resonant frequency of the heating cavity 111 is related to the inner conductor 120, the outer conductor 110 and the temperature control part at the same time. At this time, the resonant frequency of the heating cavity 111 is equal to the emission frequency of the microwave, and the resonant frequency will match the emission frequency. Therefore, the microwave can be transmitted in the heating cavity 111 and be absorbed by the atomization medium 20 , so that the host 100 is more sensitive to the atomization medium 20 heating. When the temperature of the temperature control part exceeds the critical temperature, the temperature control body 300 is transformed from a conductor into an insulator. The length of the temperature control part will not affect the resonant frequency of the heating cavity 111. That is, the length of the temperature control part does not affect the resonant frequency of the heating cavity 111. factor, since the length and cross-section of both the inner conductor 120 and the outer conductor 110 remain unchanged, and the resonant frequency of the heating cavity 111 is only related to the inner conductor 120 and the outer conductor 110 . At this time, the resonant frequency of the heating cavity 111 will change, making the resonant frequency and the emission frequency not equal, resulting in the resonant frequency not matching the emission frequency, so the microwave cannot be transmitted in the heating cavity 111 to be absorbed by the atomized medium 20, so that The host computer 100 cannot heat the atomization medium 20 . Since the host computer 100 cannot heat the atomizing medium 20 , the temperatures of the atomizing medium 20 and the temperature control part will drop to no more than the critical temperature. At this time, the temperature control part will return to a conductor, thereby causing the resonant frequency of the heating cavity 111 to return to The state that is equal to the emission frequency of the microwave ensures that the host 100 heats the atomization medium 20 again.

Therefore, by making the temperature control body 300 include a temperature control part, on the basis of allowing the atomization medium 20 to be effectively atomized, as long as the atomization temperature of the atomization medium 20 exceeds the critical temperature, the host 100 will stop heating, thereby preventing mist The atomization medium 20 is heated and atomized when the temperature is higher than the critical temperature, thereby improving the control accuracy of the atomization temperature of the atomization medium 20, preventing the atomization medium 20 from cracking due to excessive temperature to produce harmful substances with a burnt smell, and improving heating Health and safety of use of atomization device 10. In addition, the atomization temperature of the atomization medium 20 is equalized every time the user puffs, ensuring that the aerosol concentration and taste of each puff remain consistent, and providing the user with a puffing experience. Moreover, the atomization temperature of the atomization medium 20 can be controlled through the inherent properties of the thermistor, and the installation of additional control circuits can be omitted, thereby simplifying the structure of the heating atomization device 10 and achieving miniaturization of the heating atomization device 10 design. Furthermore, the temperature control body 300 and the medium carrier 200 are disposable consumables. When the atomization medium 20 is consumed, the temperature control body 300 and the medium carrier 200 will be discarded, so there is no residue on the temperature control body 300. The phenomenon of producing odorous substances after repeated heating further improves the user's smoking experience.

It is worth mentioning that, in view of the relatively large intensity of microwaves at the location of the insertion portion 122 , a certain distance is maintained between the insertion portion 122 and the side wall surface 321 of the temperature control body 300 , so that the atomized medium 20 is properly kept away from the microwaves. The position with greater intensity ensures that the atomized medium 20 is located in the area where the microwave intensity distribution is relatively uniform in the heating cavity 111. The atomized medium 20 everywhere in the bearing section 220 will have the same atomized temperature, that is, the microwave has a relatively uniform atomization temperature. It heats evenly to improve the inhalation taste of the aerosol. Further, in the case where the temperature control body 300 includes both a temperature control part and a base part made of metal, when the temperature control part is higher than the critical temperature, the resonant frequency of the heating cavity 111 has a small deviation relative to the emission frequency of the microwave. The heating cavity 111 has a small transmission function for microwaves, so that the temperature of the atomization medium 20 has a specific change curve, ensuring that the microwave heats the atomization medium 20 with a specific temperature control rule, thereby meeting the user's personalized suction needs. . Similarly, when the temperature control body 300 includes multiple temperature control parts with different critical temperatures, the temperature of the atomization medium 20 will also have a specific change curve to ensure that the microwave affects the atomization medium 20 according to a specific temperature control law. Heating can also meet the user's personalized suction needs.

The technical features of the above-described embodiments can be combined in any way. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, All should be considered to be within the scope of this manual.
