The heater is provided with a housing chamber, a circulation channel and an air inlet channel. The housing chamber is used to accommodate an atomization medium carrier. The air inlet channel is connected to the outside and one end of the housing chamber. The two ends of the circulation channel are respectively connected to the two ends of the housing chamber. The heat cycle component is arranged in the heater. When the heat cycle component is working, the gas entering the housing chamber from the outside through the air inlet channel is heated, and the gas in the housing chamber can pass through the circulation channel and then enter the housing chamber to form a circulation loop. The gas entering the housing chamber from the circulation channel has a certain amount of heat. The heat in the gas can be absorbed by the atomization medium carrier to avoid the heat from being diffused outside the heater and wasted, so that most of the heat generated by the heat cycle working component is used to heat the atomization medium carrier, thereby improving the energy utilization rate of the heater.

The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0028] See also Figure 1 , Figure 2 and Figure 3 The heating atomization device provided by an embodiment of the present invention includes a heater 20 and a power supply assembly, wherein the power supply assembly is used to supply power to the heater 20 so that the heater 20 can generate heat, and the power supply assembly and the heater 20 can be detachably connected. The heat generated by the heater 20 is used to atomize the atomization medium carrier 10, and the atomized atomization medium carrier 10 will form an aerosol that can be inhaled by the user.

[0029] See also Figure 1 and Figure 2 The atomizing medium carrier 10 may be roughly cylindrical, and the atomizing medium carrier 10 includes an atomizing section 100 , an air guiding section 200 and a suction nozzle section 300 which are connected to each other, and the air guiding section 200 is connected between the suction nozzle section 300 and the atomizing section 100 .

[0030] The atomizing section 100 includes an enclosure 110 and an atomizing medium 120, and the atomizing medium 120 is contained in a cavity surrounded by the enclosure 110. The enclosure 110 includes a side portion 111 and a bottom portion 112, the side portion 111 can be roughly a cylindrical structure, and the bottom portion 112 can be roughly a circular flat plate structure, the side portion 111 is arranged around the bottom portion 112, one end (lower end) of the side portion 111 is connected to the bottom portion 112, and the other end (upper end) of the side portion 111 is connected to the air guide section 200. Obviously, the bottom portion 112 and the side portion 111 together form a cavity of the enclosure 110, and the enclosure 110 plays a role in containing and protecting the matrix, and can prevent the atomizing medium 120 from falling out of the enclosure 110. The atomizing medium 120 can be formed by mixing aerosol generating powder, dry distillation product, atomizer, adhesive and other biomass powder in a certain mass percentage. For example, the mass percentage of aerosol generating powder can be 30% to 70%, the mass percentage of dry distillation product can be 2% to 15%, the mass percentage of atomizer can be 15% to 45%, the mass percentage of adhesive can be 1% to 6%, and the mass percentage of biomass powder can be 0 to 20%.

[0031] In some embodiments, the bottom 112 of the enclosure 110 is air-permeable, that is, the bottom 112 is an air-permeable portion. When the user inhales the atomized medium carrier 10, the gas can pass through the bottom 112 and enter the cavity of the enclosure 110. When the gas entering the cavity of the enclosure 110 is a high-temperature gas with a set high temperature, the atomized medium 120 will absorb the heat of the high-temperature gas and atomize to form an aerosol in a heating-not-burning manner, that is, the high-temperature gas directly heats the atomized medium 120. Of course, the side 111 of the enclosure 110 may be air-permeable or not.

[0032] In some embodiments, the bottom 112 and the side 111 of the inclusion 110 can prevent liquid and gas from passing through, that is, the entire inclusion 110 is a liquid-blocking and gas-isolating inclusion 110 that can prevent liquid and gas from passing through. At this time, the inclusion 110 must have good thermal conductivity, since the high-temperature gas cannot pass through the bottom 112 and the side 111 to enter the cavity of the inclusion 110, that is, the high-temperature gas cannot directly heat the atomized medium 120. However, when the inclusion 110 is in an environment surrounded by high-temperature gas, the side 111 and the bottom 112 of the inclusion 110 can absorb the heat of the high-temperature gas and transfer it to the atomized medium 120, so that the atomized medium 120 can also be atomized by heating without burning, that is, the high-temperature gas indirectly heats the atomized medium 120 through the inclusion 110. The inclusion 110 can include an aluminum foil film or a tin film, that is, the inclusion 110 is made of metal materials such as aluminum foil or tin foil, so that the inclusion 110 can be ensured to have good thermal conductivity.

[0033] The inclusion body 110 can form a detachable connection with the air guide section 200, and the atomized medium 120 can be in the form of a thread, a sheet or a granule, etc. After the atomized medium 120 in the inclusion body 110 is consumed, the inclusion body 110 can be unloaded from the air guide section 200, and then the atomized medium 120 can be continuously replenished in the cavity of the inclusion body 110 for reuse, that is, the atomized medium carrier 10 can be recycled for many times. In the case where the atomized medium 120 is granular and the high-temperature gas can pass through the inclusion body 110 to enter the cavity of the inclusion body 110, the flow rate of the high-temperature gas in the cavity is adjusted so that the granular atomized medium 120 is in a tumbling state in the cavity, which can also be figuratively understood as a "boiling" state, so that the contact probability and heat transfer efficiency between the high-temperature gas and the atomized medium 120 can be greatly increased, the atomization speed of the atomized medium 120 can be improved, and at the same time, the atomized medium 120 in each part of the cavity can be heated evenly. In other embodiments, the inclusion body 110 may also be integrally formed with the air guide section 200 , so that the atomized medium carrier 10 may be a disposable consumable.

[0034] In some embodiments, the air guide section 200 includes an air guide seat 210 and a valve core 220. The air guide seat 210 is connected to the atomization section 100. An air guide channel 211 and an air inhalation channel 212 are provided on the air guide seat 210. The two ends of the air inhalation channel 212 are respectively connected to the atomization section 100 and the mouthpiece section 300. When the user inhales, the aerosol is inhaled by the user through the air inhalation channel 212. For example, the air guide channel 211 and the air inhalation channel 212 pass through the end face of the air guide seat 210 close to the atomization section 100, that is, the air guide channel 211 and the air inhalation channel 212 have openings on the lower end face of the air guide seat 210, so that the gas in the inclusion body 110 can enter the air guide channel 211 and the air inhalation channel 212, and the air guide channel 211 is connected to the outside world. In the case where the inclusion body 110 is breathable, when the user inhales, the gas in the inclusion body 110 can enter the air guide channel 211 to flow out of the atomizing medium carrier 10, and the gas in the inclusion body 110 can also enter the air inhalation channel 212 to be absorbed by the user. In the case where the inclusion body 110 is not breathable, when the user inhales, the gas outside the atomizing medium carrier 10 can enter the air guide channel 211 to carry the aerosol atomized by the matrix 120 and be absorbed by the user through the air inhalation channel 212, and the air guide channel 211 can be directly connected to one end of the air inhalation channel 212 adjacent to the atomizing section 100; of course, the air guide channel 211 can also be indirectly connected to one end of the air inhalation channel 212 adjacent to the atomizing section 100, and at this time, the gas in the air guide channel 211 can enter the air inhalation channel 212 through the gap between the atomizing media 120. The air intake channel 212 is centrally arranged, for example, the central axis of the air intake channel 212 may coincide with the central axis of the air guide seat 210 . There are multiple air intake channels 211 , which are arranged at intervals along the circumference of the air guide seat 210 and surround the air intake channel 212 .

[0035] The air intake channel 212 includes a first channel 212a and a second channel 212b, which are interconnected and coaxially arranged. The first channel 212a is closer to the atomization section 100 than the second channel 212b, that is, the first channel 212a is located below the second channel 212b. The first channel 212a can be a cylindrical channel with the same diameter everywhere, and the second channel 212b can be a conical channel with a varying diameter. The diameter of the first channel 212a is smaller than that of the second channel 212b. Along the direction from the first channel 212a to the second channel 212b, that is, from bottom to top, the diameter of the second channel 212b gradually increases.

[0036] The valve core 220 may be spherical, and the diameter of the valve core 220 is larger than the caliber of the first channel 212a and smaller than the maximum caliber of the second channel 212b, so that the valve core 220 is located in the second channel 212b, but cannot fall completely into the first channel 212a, and the valve core 220 can move in the second channel 212b. When the user inhales, the air pressure in the second channel 212b decreases, so that the air pressure in the first channel 212a is higher than the air pressure in the second channel 212b, so there is an air pressure difference between the upper side and the lower side of the valve core 220, under the action of the air pressure difference, the valve core 220 will overcome its own gravity and move away from the first channel 212a to move upward and be in a suspended state, at this time, the valve core 220 in the suspended state (i.e., the first state) will open the upper end opening of the first channel 212a, so that the first channel 212a and the second channel 212b are connected to each other, ensuring that the aerosol generated by the atomized medium 120 enters the second channel 212b through the first channel 212a to be absorbed by the user. When the user stops inhaling, the air pressure in the first channel 212a and the second channel 212b is equal, so there is no air pressure difference between the upper and lower sides of the valve core 220. Under the action of the valve core 220's own gravity, the valve core 220 will approach the first channel 212a to move downward until it is pressed against the side wall of the second channel 212b and is in a static state (i.e., the second state). The valve core 220 in the static state will block the upper end opening of the first channel 212a, so that the first channel 212a and the second channel 212b cannot be connected to each other, thereby preventing the heated aerosol in the first channel 212a from entering the second channel 212b. At this time, the aerosol remaining in the first channel 212a can flow out of the entire atomization medium carrier 10 through the air guide channel 211.

[0037] In some embodiments, the mouthpiece section 300 includes a filter section 310 and a cooling section 320, the lower end of the cooling section 320 is connected to the air guide section 200, and the upper end of the cooling section 320 is connected to the filter section 310, that is, the cooling section 320 is connected between the air guide section 200 and the filter section 310. The user can contact the filter section 310 to inhale the aerosol. During the user's inhalation, the aerosol generated by the atomizing medium 120 passes through the first channel 212a, the second channel 212b and the cooling section 320 in sequence to enter the filter section 310. When the aerosol flows through the filter section 310, the filter section 310 can filter harmful substances in the aerosol, thereby improving the safety of the atomizing medium carrier 10. When the aerosol flows through the cooling section 320, the cooling section 320 reasonably cools the aerosol to avoid excessively high aerosol temperature and burns to the user.

[0038] See also Figure 3In some embodiments, the heater 20 includes an outer shell 400, an inner shell 500, and a thermal circulation assembly 600. The inner shell 500 is housed in the outer shell 400, and an air inlet channel 410 and a mounting hole 430 are provided on the outer shell 400. A receiving cavity 510 is provided on the inner shell 500, and a circulation channel 420 is formed between the inner shell 500 and the outer shell 400. Both the inner shell 500 and the outer shell 400 can be made of materials with high thermal insulation performance, so that the inner shell 500 and the outer shell 400 have relatively low thermal conductivity and heat capacity, thereby preventing heat from being transferred to the outside of the heater 20 through the inner shell 500 and the outer shell 400, and also preventing the outer shell 400 from generating excessively high temperatures, thereby preventing the user from having a burning discomfort when holding the outer shell 400. The mounting hole 430, the accommodating chamber 510 and the air inlet channel 410 can be coaxially arranged, the mounting hole 430 is located above the accommodating chamber 510, and the air inlet channel 410 is located below the accommodating chamber 510 and connected to the outside. Obviously, the end of the air inlet channel 410 has an end outlet 411 for gas to flow out, and the end outlet 411 is located below the accommodating chamber 510. When the user inhales, the gas entering the air inlet channel 410 can be input into the accommodating chamber 510 from the end outlet 411. The circulation channel 420 is located beside the accommodating chamber 510, and has an input port 421 and an output port 422 at both ends of the circulation channel 420, respectively. The input port 421 is arranged close to the upper end of the accommodating chamber 510, and the output port 422 is arranged close to the lower end of the accommodating chamber 510, so that the two ends of the circulation channel 420 are respectively connected to the two ends of the accommodating chamber 510, so that the gas in the accommodating chamber 510 can enter the circulation channel 420 from the input port 421, and the gas in the circulation channel 420 can flow out from the output port 422 to enter the accommodating chamber 510.

[0039] The accommodating chamber 510 has a baking section 511 and a mounting section 512 which are interconnected. The baking section 511 is located above the mounting section 512, that is, the mounting section 512 is closer to the terminal outlet 411 of the air inlet channel 410 than the baking section 511, and the caliber of the mounting section 512 can be equal to the caliber of the baking section 511. When the atomized medium carrier 10 is inserted into the heater 20, the atomizing section 100 of the atomized medium carrier 10 is accommodated in the baking section 511, the suction nozzle section 300 or the air guide section 200 of the atomized medium carrier 10 can be matched with the mounting hole 430, and the filter part 310 is exposed outside the housing 400 for suction. The air guide channel 211 on the air guide section 200 corresponds to the input port 421 of the circulation channel 420. A limiting structure such as a baffle can be set between the baking section 511 and the installation section 512. When the atomization section 100 abuts against the baffle, the baffle limits the entire atomization medium carrier 10 in the axial direction of the heater 20 to prevent the atomization section 100 from continuing to move downward to enter the installation section 512.

[0040] The heat circulation assembly 600 is accommodated in the installation section 512. The heat circulation assembly 600 includes a heating element 610 and a circulation fan 620. The heating element 610 and the circulation fan 620 are arranged at intervals along the axial direction of the entire heater 20. The heating element 610 can be located above the circulation fan 620, so that the circulation fan 620 is closer to the terminal outlet 411 of the air inlet channel 410 and the output port 422 of the circulation channel 420 relative to the heating element 610. The circulation fan 620 has an air inlet 621 and an air outlet 622. The air outlet 622 is located above the air inlet 621, that is, the air outlet 622 is farther away from the terminal outlet 411 of the air inlet channel 410 relative to the air inlet 621. The heating element 610 is electrically connected to the power supply assembly so that the power supply assembly supplies power to the heating element 610. The heating element 610 can be a metal heating wire with high thermal conductivity or a porous metal, or a plasma discharge source or a laser source. In other embodiments, the thermal cycle component 600 may also be accommodated at a position where the air inlet channel 410 is adjacent to the accommodating chamber 510 , and the thermal cycle component 600 may also be located between the air inlet channel 410 and the accommodating chamber 510 .

[0041] See also Figure 3 In the case where the heater 20 atomizes the atomizing medium carrier 10 having air permeability in the encapsulation body 110, with the inner side surface 520 of the inner shell 500 used to define the boundary of the entire accommodating cavity 510 as a reference, when the atomizing section 100 is accommodated in the baking section 511, the side 111 of the atomizing section 100 is pressed against the inner side surface 520, so that there is no gap between the side 111 of the atomizing section 100 and the inner side surface 520. In layman's terms, the atomizing section 100 and the baking section 511 form a tight fit. When the user inhales in the filtering section, the heating element 610 starts to work, and the external low-temperature gas entering the air inlet channel 410 is heated by the heating element 610 from the terminal outlet 411 to form high-temperature gas and enters the baking section 511. Since the inclusion body 110 has air permeability, the high-temperature gas will enter the cavity of the inclusion body 110 to directly heat the atomizing medium 120. The atomizing medium 120 absorbs heat and atomizes to form an aerosol. Since the valve core 220 has opened the inhalation channel 212, the aerosol passes through the inhalation channel 212 and finally enters the filtering section to be absorbed by the user.

[0042] While the heating element 610 is working, the circulating fan 620 is turned on, and the part of the gas with temperature (referred to as medium-temperature gas) after heat exchange in the enclosure 110 (i.e., in the accommodating chamber 510) will enter the circulation channel 420 from the air guide channel 211 through the input port 421, and then flow out from the output port 422 of the circulation channel 420, and then enter from the air inlet 621 of the circulating fan 620 and output from the air outlet 622 to enter the enclosure 110 of the baking section 511. Therefore, through the action of the circulating fan 620, the medium-temperature gas can form a circulation loop between the circulation channel 420 and the baking section 511. During the flow of the medium-temperature gas in the circulation channel 420, the medium-temperature gas will absorb the heat on the inner shell 500 and the outer shell 400 to re-enter the baking section 511 to be absorbed by the atomizing medium 120. In this way, on the one hand, the gas can recycle energy, improve the energy utilization rate of the heating element 610, and prevent heat from being transmitted to the housing 400 and causing burning discomfort to the user. On the other hand, when the medium-temperature gas in the circulation channel 420 and the low-temperature gas in the air inlet channel 410 are mixed with each other and then heated by the heating element 610 to form a high-temperature gas with a set high temperature, since the low-temperature gas can absorb the heat of the medium-temperature gas, the formation time of the high-temperature gas can be reduced when the power of the heating element 610 remains unchanged, that is, the heating speed of the high-temperature gas is increased, thereby increasing the atomization speed of the atomization medium 120, and then improving the suction sensitivity of the heater 20.

[0043] When the user stops inhaling, the heating element 610 can stop working immediately. During the short pause between two adjacent inhalations, although the heating element 610 stops working, the circulating fan 620 can still work. Since the valve core 220 blocks the air inhalation channel 212 when the user stops inhaling, the aerosol with temperature remaining in the air inhalation channel 212 and the accommodating chamber 510 cannot be transmitted from the air inhalation channel 212 to the atmosphere, the aerosol with temperature will enter the baking section 511 from the air guide channel 211 through the circulation channel 420 to form a circulation loop. In this way, the heat of the residual aerosol can be fully utilized, so that the aerosol with temperature will have a good preheating effect on the atomizing medium 120, so that the atomizing medium 120 has a reasonable preheating temperature. When the user inhales again, the atomizing medium 120 can be atomized to form an aerosol from the preheating temperature to the atomizing temperature in a relatively short time, thereby increasing the atomization speed of the atomizing medium 120. Likewise, energy waste can be reduced and the energy utilization rate of the heater 20 can be improved.

[0044] When the medium-temperature gas forms a circulation loop between the circulation channel 420 and the baking section 511, the speed of the airflow in the circulation loop can be adjusted by adjusting the power of the circulation fan 620. For the granular atomizing medium 120, a reasonable airflow speed will cause the atomizing medium 120 to produce a tumbling effect in the inclusion body 110, which can greatly increase the contact probability and heat transfer efficiency between the high-temperature gas and the atomizing medium 120, improve the atomization speed of the atomizing medium 120, and ensure that the atomizing medium 120 in each part of the inclusion body 110 is heated evenly, so that the aerosol concentration of the user is consistent each time the user draws, and improve the suction taste and user experience.

[0045] See also Figure 4In the case where the heater 20 atomizes the atomizing medium carrier 10 whose encapsulation body 110 is not air-permeable, the inner side surface 520 of the inner shell 500 used to define the boundary of the entire accommodating chamber 510 is also used as a reference. When the atomizing section 100 is accommodated in the baking section 511, the side portion 111 of the atomizing section 100 and the inner side surface 520 do not form a pressing effect, so that there is a gap between the side portion 111 of the atomizing section 100 and the inner side surface 520, and the gap is the flow gap 511a. The flow gap 511a is connected to the input port 421 of the circulation channel 420. Obviously, the flow gap 511a is a part of the accommodating chamber 510. When the user inhales and the heating element 610 and the circulating fan 620 are working, the low-temperature gas in the air inlet channel 410 is heated by the heating element 610 to form high-temperature gas entering the circulation gap 511a. Since the inclusion body 110 has good thermal conductivity, although the high-temperature gas cannot enter the inclusion body 110 and directly contact the atomizing medium 120, the heat of the high-temperature gas will be transmitted to the atomizing medium 120 through the inclusion body 110 to indirectly heat and atomize it. At the same time, the valve core 220 opens the air inhalation channel 212, and the gas will enter from the air guide channel 211 and carry the aerosol out of the air inhalation channel 212 to be absorbed by the user. Since the high-temperature gas does not enter the inclusion body 110, the atomizing medium 120 will be in an oxygen-deficient baking environment. On the one hand, the harmful gas obtained by the reaction of the atomizing medium 120 with oxygen can be eliminated, thereby improving the safety of the use of the heater 20. On the other hand, the composition and concentration of the aerosol can also be changed to a certain extent, so that the atomizing medium carrier 10 has a different suction taste. Similarly, the circulating fan 620 can allow the medium-temperature gas formed by heat exchange in the circulation gap 511a to enter the circulation channel 420 from the input port 421, and then enter the circulation gap 511a from the circulation channel 420 to form a circulation loop, so that the medium-temperature gas will absorb the heat on the inner shell 500 and the outer shell 400 to enter the circulation gap 511a and be absorbed by the atomizing medium 120. Referring to the above description of the heater 20 atomizing the atomizing medium carrier 10 of the air-permeable enclosure 110, this can also improve the energy utilization of the heating element 610 and the atomizing speed of the atomizing medium 120, and avoid the discomfort of burning caused by the heater 20.

[0046] During the short pause between two adjacent inhalations, the circulating fan 620 can continue to work. Since the valve core 220 blocks the inhalation channel 212 when the user stops inhaling, the aerosol with temperature remaining in the inhalation channel 212 and the accommodating chamber 510 cannot be transmitted from the inhalation channel 212 to the atmosphere. The aerosol with temperature will enter the circulation gap 511a from the air guide channel 211 through the circulation channel 420 to form a circulation loop, so that the heat of the residual aerosol can be fully utilized, so that the aerosol with temperature will have a good preheating effect on the atomizing medium 120. When the user inhales again, the atomizing medium 120 can be raised to the atomizing temperature in a short time, thereby improving the atomizing speed of the atomizing medium 120 and the energy utilization rate of the heater 20.

[0047] Since the inclusion body 110 also has liquid isolation properties, it can effectively prevent the tar and other liquids generated by the atomization medium 120 from seeping out of the inclusion body 110, prevent the liquid from polluting the accommodating cavity 510, and prevent the liquid from further dripping onto the thermal cycle component 600 to corrode it.

[0048] See also Figure 5 In some embodiments, with reference to the inner side surface 520 of the inner shell 500 defining the boundary of the entire accommodating cavity 510, the heating element 610 can maintain a certain distance from the inner side surface 520. When the heating element 610 and the circulating fan 620 are working, the heat transferred to the inner shell 500 can be reduced, so that the heat on the heating element 610 is concentrated on heating the low-temperature gas from the air inlet channel 410. In other embodiments, the heating element 610 can abut against the inner side surface 520, thereby eliminating the gap between the heating element 610 and the inner side surface 520.

[0049] See also Figure 4 , Figure 5 and Figure 6In some embodiments, the caliber of the installation section 512 is smaller than the caliber of the baking section 511. Specifically, the baking section 511 may be a columnar structure with a constant caliber. The installation section 512 includes a first subsection 512a and a second subsection 512b that are interconnected. The caliber of the first subsection 512a is larger than the caliber of the second subsection 512b. The first subsection 512a is located between the baking section 511 and the second subsection 512b, so that the second subsection 512b is closer to the output port 422 and the terminal outlet 411 relative to the first subsection 512a. The first subsection 512a may be a tapered structure with a variable caliber. The caliber of the first subsection 512a decreases in the direction from the first subsection 512a to the second subsection 512b. In layman's terms, the caliber of the first subsection 512a is larger at the top and smaller at the bottom. The second subsection 512b may be a columnar structure with a constant caliber. The heating element 610 is accommodated at one end of the first subsection 512a close to the second subsection 512b, and the circulating fan 620 is accommodated in the second subsection 512b. Therefore, when the heating element 610 is working, the heat of the heating element 610 can be concentrated in a relatively small space, increasing the contact opportunity between the low-temperature gas and the heat, thereby increasing the heating speed of the low-temperature gas, and further increasing the atomization speed of the atomization medium 120.

[0050] In some embodiments, a temperature control body is also included, and the temperature control body is used to detect the temperature of the gas. The position close to the input port 421 is the first position, and the position between the atomizing medium carrier 10 and the thermal cycle component 600 in the accommodating chamber 510 is the second position. A temperature control body is provided at the first position so that the temperature control body can detect the temperature of the gas flowing from the accommodating chamber 510 into the circulation channel 420. Alternatively, a temperature control body is provided at the second position so that the temperature control body can detect the temperature of the gas heated by the heating body. Alternatively, a temperature control body is provided at both the first position and the second position. By monitoring the gas temperature, the power of the heating element 610 and the circulating fan 620 can be adjusted to the optimal state through the temperature information, so as to minimize energy waste and improve its utilization rate.

[0051] In some embodiments, the axial distance between the input port 421 and the output port 422 along the heater 20 is a first length A, the extending length of the accommodating cavity 510 along the axial direction of the heater 20 is a second length B, and the first length A is greater than or equal to the second length B. In this way, the gas in the circulation channel 420 can fully contact the inner shell 500 to maximize the recovery of energy on the inner shell 500, further improving the energy utilization rate.

[0052] In some embodiments, the heater 20 further includes a puncture body, which is disposed near the input port 421 of the circulation channel 420, and the puncture body can generate telescopic movement relative to the inner shell 500. When the heater 20 atomizes the common atomized medium carrier 10, since the atomized medium carrier 10 does not have an air guide channel 211, during the process of inserting the atomized medium carrier 10 into the accommodating cavity 510, the puncture body will form an air guide channel 211 on the atomized medium carrier 10, so that the medium-temperature gas in the baking section 511 enters the circulation channel 420 through the air guide channel 211 and enters the baking section 511 again to form a circulation loop.

[0053] See also Figure 6 In some embodiments, the heater 20 further comprises a mounting cylinder 700, the mounting cylinder 700 comprises a cylinder portion 710 and a suction portion 720, the cylinder portion 710 is located in the baking section 511, the cylinder portion 710 is provided with a receiving cavity 711, the suction portion 720 is provided with an air guide channel 211 connected to the receiving cavity 711, there is a flow gap 511a between the cylinder portion 710 and the inner side surface 520 of the inner shell 500 connected to the circulation channel 420, the receiving cavity 711 is used to accommodate the atomized medium 120, the cylinder portion 710 can prevent liquid and gas from passing through, that is, the cylinder portion 710 is a liquid-blocking and gas-isolating cylinder. At the same time, the cylinder portion 710 has good thermal conductivity. The suction portion 720 is penetrated in the mounting hole 430, and a part of the suction portion 720 is located outside the outer shell 400 for suction. The cylinder portion 710 and the suction portion 720 can be in a detachable connection relationship, and the suction portion 720 and the outer shell 400 can also be in a detachable connection relationship. After the barrel 710 is unloaded from the suction part 720, the atomized medium 120 can be added to the receiving chamber 711 of the barrel 710, and then the barrel 710 and the suction part 720 are assembled into the installation barrel 700, and then the suction part 720 is connected to the housing 400, so that the barrel 710 is located in the baking section 511. When the barrel 710 is located in the baking section 511, the air guide channel 211 and the flow gap 511a are connected to each other.

[0054] See also Figure 4 and Figure 6In fact, the installation cylinder 700 containing the atomizing medium 120 can be equivalent to the atomizing medium carrier 10 whose enclosure 110 is not air-permeable. For the working principle of the heater 20 in this embodiment, reference can be made to the working principle of the heater 20 in the above embodiment for atomizing the atomizing medium carrier 10 whose enclosure 110 is not air-permeable. In short, when the user inhales in the suction part 720, the low-temperature gas from the air inlet channel 410 is heated by the heating body to form a high-temperature gas to enter the flow gap 511a. The heat of the high-temperature gas is transferred to the atomizing medium 120 through the cylinder 710, so that the atomizing medium 120 is heated by oxygen depletion and atomized to form an aerosol. At the same time, the gas enters the receiving cavity 711 from the air guide channel 211 to carry the aerosol to be inhaled by the user. Under the action of the circulation fan 620, the medium-temperature gas formed by heat exchange in the circulation gap 511a enters the circulation channel 420 from the input port 421, and then enters the circulation gap 511a from the circulation channel 420 to form a circulation loop, so that the heat of the medium-temperature gas is transferred to the atomizing medium 120 through the cylinder 710. Within the short pause process between two adjacent suctions, the circulation fan 620 can continue to work, and the warm aerosol remaining in the installation cylinder 700 will enter the circulation gap 511a from the air guide channel 211 through the circulation channel 420 to form a circulation loop, so that the heat of the residual aerosol can be fully utilized, so that the warm aerosol will have a good preheating effect on the atomizing medium 120.

[0055] In some embodiments, the heating element 610 further includes a blocking element 800, which is located between the inner shell 500 and the outer shell 400, so that the blocking element 800 is located between the air inlet passage 410 and the accommodating chamber 510. Specifically, the blocking element 800 is located above the terminal opening of the air inlet passage 410 and below the accommodating chamber 510, and the orthographic projection of the blocking element 800 on the outer shell 400 can cover the terminal opening of the air inlet passage 410. Of course, the orthographic projection of the blocking element 800 on the inner shell 500 can also cover the accommodating chamber 510.

[0056] During suction, due to the blocking effect of the blocking member 800, the external low-temperature gas in the air inlet channel 410 cannot move along a straight trajectory to the heating body for heating. The low-temperature gas will flow along a curved trajectory and bypass the circulation channel 420, and reach the heating member 610 from the output port 422 of the circulation channel 420 for heating. In this way, the flow path of the low-temperature gas will be appropriately extended, so that the low-temperature gas has enough time in the circulation channel 420 to exchange heat with the medium-temperature gas in the circulation channel 420, and then the low-temperature gas and the medium-temperature gas after the heat exchange will form a mixed gas with a temperature higher than that of the low-temperature gas. When the mixed gas reaches the heating member 610, the mixed gas can be quickly heated to a set high temperature in a short time to form a high-temperature gas that can fully atomize the atomizing medium 120. It effectively prevents the low-temperature gas from being unable to heat up to the set high temperature in a short time due to arriving at the heating member 610 along a straight line, thereby reducing the interference of the gas that has not reached the set high temperature on the temperature field in the baking section 511, and ultimately improving the heating and atomization effect of the atomizing medium 120.
