The heat sink 310 has a combustion chamber 330 formed at an end thereof remote from the material container 200, and the combustion chamber 330 is in communication with the exhaust gas discharge hole 120, and the exhaust gas discharge hole 120 is used for discharging the exhaust gas after combustion in the combustion chamber 330, including but not limited to carbon dioxide, carbon monoxide, etc. The fuel heater 400 is disposed in the outer casing 100, the fuel heater 400 includes a fuel tank 410 for accommodating fuel and a burner head 420 connected to the fuel tank 410, the burner head 420 is disposed in the combustion chamber 330, the burner head 420 is used for heating the heat sink 310 by burning the fuel in the fuel tank 410, so that the heat of the heat sink 310 is conducted to the air in the pipeline 320, and the heated air is conducted to the material container 200 to heat and atomize the herbal material.

The herbal substances may be low-temperature non-combustible tobacco products, or other types of aerosol-generating products, such as tobacco leaves, cut tobacco, etc., which may be determined according to the actual use requirements of users, and the embodiment is not limited in particular.

In this embodiment, the herbal material is preferably a tobacco product that does not burn at low temperature. The low-temperature non-combustible tobacco product mainly refers to an aerosol-generating product made of materials such as cut tobacco, tobacco particles, plant fragments, tobacco essence, propylene glycol and the like, and the aerosol-generating product is generally in a column shape (such as a cylinder shape), so that the low-temperature non-combustible tobacco is also called, under the condition of low-temperature heating, volatile substances such as nicotine and other aromatic substances in the low-temperature non-combustible tobacco product can volatilize under the condition of not generating solid particles, and only atomized steam is generated. It is understood that low temperature herein refers to a temperature that enables the herbal species to generate an aerosol without burning, typically 200-400 ℃.

In this embodiment, the heat dissipation element 310 and the pipe 320 may be metal elements, which have better heat conduction effect. For example, the heat sink 310 and the pipe 320 may be made of at least one material of copper, aluminum, nichrome, iron-chromium-aluminum, stainless steel, etc. It should be noted that, the heat sink 310 and the pipe 320 may be made of the same material, for example, stainless steel materials are used for the heat sink 310 and the pipe 320; alternatively, the heat sink 310 and the pipe 320 may be made of different materials, for example, stainless steel material is used for the heat sink 310, and aluminum material is used for the pipe 320, which is not limited herein.

In this embodiment, the heat exchanger 300 is located below the material container 200, the combustion chamber 330 is located at an end of the heat sink 310 away from the material container 200, and the combustion head 420 of the fuel heater 400 is located in the combustion chamber 330, i.e. the combustion chamber 330 is located between the heat sink 310 and the fuel heater 400. Thus, in order to save the internal space of the outer case 100, the heat exchanger 300 and the fuel heater 400 are sequentially disposed inside the outer case 100 from top to bottom as shown in fig. 2. The material container 200 is disposed at the upper end outside the outer casing 100, and the fuel heater 400 is disposed at the lower end inside the outer casing 100, so that the heat exchanger 300 is disposed between the material container 100 and the fuel heater 400, and the combustion head 420 of the fuel heater 400 heats the heat sink 310 after burning the fuel in the fuel tank 410. In this way, the heat generated by heating the heat sink 310 is transferred to the pipe 320 connected thereto, thereby heating the air transferred from the outside into the pipe 320. Because the other end of the pipe 320 extends into the material container 200 and is communicated with the inner space of the material container 200, the heated air in the pipe 320 can be conducted into the material container 200 to heat and atomize the herbal substances in the material container 200.

It should be noted that, the positions of the heat exchanger 300 and the fuel heater 400 in the outer housing 100 are not required to be set as described above, and may be set in other manners, for example: the combustion chamber 330 is disposed at the left side or the right side (not shown) of the heat sink 310, and in this case, the fuel heater 400 may be disposed side by side with the heat exchanger 300, while the combustion head 420 of the fuel heater 400 is still disposed in the combustion chamber 330, etc., which is not limited thereto.

According to the technical scheme provided by the invention, the heat exchanger 300 and the fuel heater 400 are sequentially arranged in the outer shell 100, the heat exchanger 300 comprises the heat radiating piece 310 and the pipeline 320 connected with the heat radiating piece 310, one end of the pipeline 320 is communicated with the air inlet 110, the other end of the pipeline 320 is communicated with the material container 200, the fuel heater 400 comprises the fuel tank 410 for containing fuel and the combustion head 420 connected with the fuel tank 410, and the combustion head 420 is positioned in the combustion chamber 330 formed by one end, far away from the material container 200, of the heat radiating piece 310 by combusting the fuel in the fuel tank 410, at the moment, the heat generated by heating the heat radiating piece 310 can be conducted into the air in the pipeline 320, and the heated air is conducted into the material container 200, so that the heating and atomization of herbal substances in the material container 200 are realized. That is, the heat sink 310 is heated by burning the fuel in the fuel tank 410 by the burner 420, and the heat generated by heating the heat sink 310 is transferred to the material container 200 by heat conduction, so as to heat and atomize the herbal material. In this way, the fuel heater 400 provides heat to the heat exchanger 300 by burning fuel through the burner 420, without relying on a host power source as power, so that the fuel heater 400 can be started for use even in the outdoor without power source or in extreme air temperature, and the applicability of the electronic atomization device is improved. In addition, the electronic atomization device does not depend on the host power supply as power, so that the electric energy consumption of the host power supply can be reduced, the cruising ability of the host power supply can be prolonged, and the service life of the host power supply can be prolonged.

Further, as shown in fig. 2, 3 and 5, the material container 200 includes a container body 210 and a receiving chamber 220 connected with the container body 210, the container body 210 is connected above the outer housing 100, a receiving cavity 221 for receiving the herbal material is formed in the receiving chamber 220, at least one air hole 223 penetrating into the receiving cavity 220 is formed in the bottom of the receiving chamber 220, the air hole 223 is used for communicating the receiving cavity 221 with the pipe 320, so that heated air in the pipe 320 is conducted into the receiving cavity 221 through the air hole 223, and heating atomization of the herbal material in the receiving cavity 221 is achieved.

In order to facilitate insertion or placement of the tobacco product formed of the herbal material into the accommodating chamber 221, the accommodating chamber 221 in this embodiment is shaped to match the tobacco product formed of the herbal material, for example: may be provided in a columnar shape or the like, and is not limited herein.

In this embodiment, since the hot air outlet of the duct 320 is disposed opposite to the bottom of the accommodating chamber 220, that is, the hot air outlet of the duct 320 is disposed opposite to the air hole 223, the position of the air hole 223 is designed to have two functions. One function is to conduct the heated air in the duct 320 into the receiving chamber 221, and the heated air heats and atomizes the herbal material in the receiving chamber 221. In addition, since one end of the duct 320 is directly connected to the air intake hole 110, the outside air may contain dust or other floating particles when the outside air is introduced into the duct 320 from the air intake hole 110. Another function of the air hole 223 is that even if the pipe 320 contains dust or other floating particles, the dust or other floating particles can be filtered through the air hole 223, so that when the user sucks the smoke, the smoke may contain part of the dust or other floating particles, and the user's sucking experience is improved.

It should be noted that, the number of the air holes 223 is preferably plural, so that the hot air in the pipe 320 is more conducted into the accommodating cavity 221, and the arrangement manner and the specific number of the air holes 223 may be set according to the actual requirement, which is not limited herein.

Alternatively, the container body 210 is of unitary construction with the receiving compartment 220.

Further, as shown in fig. 6 and 7, the heat dissipation member 310 is integrally in a column shape, the heat dissipation member 310 is distributed with a plurality of heat dissipation plates 311 along its own circumference, and the adjacent heat dissipation plates 311 are arranged at intervals, wherein the pipe 320 is spirally wound around the outer circumference of the heat dissipation member 310. Here, the adjacent heat dissipation plates 311 are disposed at intervals in such a manner that one ends of the plurality of heat dissipation plates 311 are commonly connected to the central axis of the heat dissipation member 310, and the adjacent heat dissipation plates 311 are disposed at an angle, so that the other ends of the plurality of heat dissipation plates 311 are disposed at intervals.

In this embodiment, the pipe 320 may be spirally embedded in the periphery of the heat dissipation plate 311 along the circumferential direction of the heat dissipation member 310 (as shown in fig. 2 and 3), so that the heat dissipation plate 311 is in full contact with each portion of the pipe 320, and thus, more heat generated after the heat dissipation plate 311 is heated is conducted to the pipe 320 by heat conduction, so that the air in the pipe 320 is heated more quickly and more uniformly. It should be noted that, one end of the pipe 320 near the air inlet 110 and the other end near the material container 200 need to extend from the periphery of the heat dissipation plate 311, so that the pipe 320 can communicate the air inlet 110 with the material container 200.

Alternatively, the pipe 320 may be spirally laid on the outer periphery (not shown) of the heat dissipation plate 311 along the circumferential direction of the heat dissipation member 310, so that heat generated after the heat dissipation plate 311 is heated is conducted to the pipe 320 in a heat conduction manner, and an effect of heating the air in the pipe 320 is achieved.

The heat sink 310 in this embodiment has a combustion chamber 330 formed at an end thereof remote from the material container 200. In some structural designs of the present embodiment, the combustion chamber 330 may be provided in two ways.

Specifically, the first arrangement mode of the combustion chamber 330 is that the inner periphery of one end of each heat dissipation plate 311 away from the material container 200 is formed with a combustion chamber 330 (as shown in fig. 2 to 4) having a cavity. As shown in fig. 2 to 4, 8 and 9, the heat dissipation plate 311 includes a connection portion 3110 and an extension portion 3112 connected to the connection portion 3110, the extension portion 3112 is disposed at an end of the connection portion 3110 away from the material container 200, that is, the extension portion 3112 is disposed below the connection portion 3110. The connection portion 3110 of each heat dissipation plate 311 is configured to be connected to the connection portion 3110 of the other heat dissipation plates 311, each extension portion 3112 is provided with a notch 3113 towards the central axis of the heat dissipation member 310, and the notches 3113 on the extension portions 3112 of all the heat dissipation plates 310 enclose to form a cavity, which is the combustion chamber 330 described above. In this way, when the combustion head 420 is located in the combustion chamber 330 to combust fuel, the heat generated by the combustion of the combustion head 420 is dissipated to the heat dissipation plate 311 more, so that the heat dissipation plate 311 is heated more uniformly. In addition, the adjacent heat dissipation plates 311 are spaced apart from each other, and a gap is formed between the heat dissipation plates to conduct exhaust gas generated by the combustion of the fuel by the combustion head 420 in the combustion chamber 330 to the exhaust gas discharge hole 120, thereby discharging the exhaust gas from the exhaust gas discharge hole 120 to the outside of the electronic atomizing device.

Further, the notch 3113 is arc-shaped (as shown in fig. 8), and the combustion chamber 330 formed by enclosing the notch 3113 with the arc-shaped structure is dome-shaped; alternatively, the shape of the notch 3113 may be square, and the shape of the combustion chamber 330 formed by enclosing the notch 3113 with a square structure may be square (as shown in fig. 9). Of course, the shape of the notch 3113 is not limited to the arc shape or the square shape, but may be a triangle shape, a trapezoid shape, or a combination of two or more patterns, and is not limited thereto.

The second arrangement of the combustion chamber 330 is that the outer end of each heat dissipation plate 311 far away from the material container 200 is provided with a combustion chamber 330 (not shown) with a cavity. Specifically, the combustion chamber 330 is a combustion chamber structure having a cavity provided between the heat dissipation plate 311 and the fuel tank 410, such as: combustion chamber, combustion room, etc., at this time, combustion chamber 330 and heat dissipation plate 311 are in contact with each other, so that heat generated by combustion of combustion head 420 in the space of combustion chamber 330 can be conducted to heat dissipation plate 311, and heat dissipation is performed to heat dissipation plate 311. In addition, the combustion chamber 330 is disposed in communication with the gap formed between the adjacent heat dissipation plates 311 such that the exhaust gas generated by the combustion of the fuel by the combustion head 420 in the combustion chamber 330 is conducted to the exhaust gas discharge hole 120 through the gap formed between the adjacent heat dissipation plates 311, thereby discharging the exhaust gas from the exhaust gas discharge hole 120 to the outside of the electronic atomizing device.

Further, the exhaust gas discharge hole 120 is disposed through the sidewall of the outer housing 100 corresponding to the region where the heat dissipation plate 311 is located, or the exhaust gas discharge hole 120 is disposed through the sidewall of the outer housing 100 corresponding to the region where the heat dissipation plate 311 is located, so that the exhaust gas in the combustion chamber 330 can be discharged to the outside of the electronic atomization device through the gaps between the heat dissipation plates 311 and the exhaust gas discharge hole 120.

In this embodiment, the exhaust hole 120 is disposed through a side wall of the outer housing 100 above a region corresponding to the heat dissipation plate 311, and the outer housing 100 includes a main housing 130 and an exhaust seat 140 disposed at an upper end of the main housing 130. Wherein the exhaust gas discharge hole 120 is provided on the outer peripheral wall of the exhaust gas discharge seat 140.

Specifically, the heat exchanger 300 and the fuel heater 400 are sequentially disposed in the main housing 130 from top to bottom, the air inlet 110 is disposed on the main housing 130, and the air inlet 110 is disposed in a region between the heat exchanger 300 and the fuel heater 400, that is, the air inlet 110 is disposed below the heat exchanger 300, so that after one end of the pipe 320 is connected with the air inlet 110, when the other end of the pipe 320 is spirally wound around the periphery of the heat dissipation member 310, the pipe 320 can contact with more heat dissipation plates 311, thereby enabling air in the pipe 320 to be heated faster and more uniformly.

As shown in fig. 2, 3 and 5, the exhaust gas emission seat 140 is disposed at one end of the main housing 130 near the heat exchanger 300, and the exhaust gas emission seat 140 has a hollow hole 141 penetrating through in the axial direction of the electronic atomization device, the other end of the pipe 320 is disposed in communication with the hollow hole 141, and the hollow hole 141 is disposed in communication with the space in the material container 200. Wherein, the hollow hole 141 is communicated with the holding bin 220 in the material container 200 through the air hole 223 (fig. 2), so that the hot air in the pipeline 320 is conducted into the holding bin 220 through the air hole 223, and the herbaceous substances in the holding cavity 221 of the holding bin 220 are heated and atomized.

Alternatively, the exhaust gas discharge hole 120 is provided on the outer peripheral wall of the exhaust gas discharge seat 140, and the exhaust gas discharge hole 120 is provided in communication with the combustion chamber 330 through a gap formed between the adjacent heat dissipation plates 311.

In the present embodiment, the main housing 130 and the exhaust seat 140 may be integrally formed. The material container 200 and the main housing 130 may be integrally formed, or the material container 200 and the main housing 130 may be separately formed.

Further, the material container 200 and the main housing 130 are preferably in a split structure, that is, the material container 200 and the main housing 130 are detachably connected. In order to achieve the connection between the material container 200 and the main housing 130, as shown in fig. 2, 3 and 5, the electronic atomization device may further include an upper sleeve 500, wherein the upper sleeve 500 is sleeved on the exhaust emission seat 140, and the material container 200 is disposed in the upper sleeve 500 and is in communication with the hollow hole 141. That is, the upper sleeve 500 is connected to the exhaust gas discharge seat 140 of the outer housing 100, and the material container 200 is connected to the upper sleeve 500, thereby achieving the interconnection between the material container 200, the upper sleeve 500, and the outer housing 100. The material container 200, the upper sleeve 500, and the outer case 100 are detachably connected to each other.

Because the material container 200 is sleeved in the upper sleeve 500, the accommodating chamber 220 is located in the space inside the upper sleeve 500, at this time, a gap space is formed between the outer side wall of the accommodating chamber 220 and the inner side wall of the upper sleeve 500, and the other end of the pipe 320 is connected to the hollow hole 141 of the exhaust emission seat 140, so that part of the hot air of the pipe 320 is conducted into the gap space formed between the accommodating chamber 220 and the upper sleeve 500, resulting in a reduction of the hot air conducted into the accommodating chamber 220. For this reason, the electronic atomizing device in the present embodiment further includes a heat insulating member 600, and the heat insulating member 600 is disposed between the outer sidewall of the material container 200 and the inner sidewall of the upper sleeve 500, and is disposed at a distance from the outer sidewall of the material container 200 and the inner sidewall of the upper sleeve 500, respectively. At this time, a heat conducting space 610 is formed between the outer sidewall of the accommodating compartment 220 and the heat insulating member 600, and the heat conducting space 610 can accommodate part of the hot air conducted from the pipe 320, so that the hot air in the heat conducting space 610 can be conducted to the sidewall of the accommodating cavity 221 through the sidewall of the accommodating compartment 220, thereby heating and/or preheating the side surface of the herbal material. And the bottom of the accommodating bin 220 is provided with an air hole 223, and most of the hot air in the pipeline 320 is conducted into the accommodating cavity 221 from the air hole 223, so that the herbaceous substances are heated and atomized from the bottom of the herbaceous substances. In this way, the hot air conducted into the heat conducting space 610 and the hot air at the bottom of the accommodating cavity 221 can make the atomization of the herbal substances more sufficient and the atomization efficiency higher.

Further, as shown in fig. 1, 2, 4 and 5, an observation hole 150 is provided at the outer circumference of the main housing 130, the observation hole 150 being provided opposite to the position of the combustion chamber 330 so that the combustion condition of the combustion head 420 in the combustion chamber 330 can be directly observed through the observation hole 150.

Based on the above embodiments, as shown in fig. 2 to 4 and 10, the fuel heater 400 further includes a gas regulating assembly 430 (refer to the following description for the components included in the gas regulating assembly 430), a fire dividing cover 440, and an igniter 450. Wherein, the fuel tank 410 is provided with an air outlet pipe 411 near one end of the heat dissipation member 310, the air adjusting component 430 is sleeved on the air outlet pipe 411, and the air adjusting component 430 is used for adjusting the flow of the fuel flowing through the air outlet pipe 411. The fire dividing cover 440 is disposed in the combustion chamber 330, and the fire dividing cover 440 is hermetically connected to the gas regulating assembly 430, a fuel cavity 441 is disposed at one end of the fire dividing cover 440 close to the gas regulating assembly 430, at least one burner head 420 is disposed at one end of the fire dividing cover 440 far away from the gas regulating assembly 430, a fuel through hole 442 penetrating through the fuel cavity 441 is disposed on each burner head 420, and an igniter 450 is disposed at one side of the burner head 420 far away from the fuel cavity 441, so that the stored fuel in the fuel tank 410 is conducted to the fuel cavity 441 through the gas outlet pipe 411, then conducted to the fuel head 420 through the fuel through hole 442, and the igniter 450 performs an ignition operation, thereby enabling the fuel to burn at the burner head 420.

It should be noted that, in the above description, on the premise that the air regulating assembly 430 communicates the air outlet 411 with the fuel cavity 441, the fuel in the fuel tank 410 is provided to the burner 420 through the air outlet 411, the fuel cavity 441 and the fuel through hole 442, and is combusted after the igniter 450 starts the ignition operation.

Further, the number of the plurality of the burner heads 420 is preferably plural, the plurality of burner heads 420 are uniformly distributed in the combustion chamber 330, so that the heat generated by burning fuel by the plurality of burner heads 420 can uniformly heat the heat dissipation plate 311, and the arrangement mode and the specific number of the burner heads 420 can be set according to the actual requirement, which is not limited herein. The bottom of the fuel tank 410 is provided with an inflation hole 4102, and the inflation hole 4102 is used for externally connecting an inflation device to charge fuel into the fuel tank 410.

Specifically, the air adjusting assembly 430 includes a plug body 431 and a penetrating column 432, the plug body 431 is sleeved on the outer wall of the air outlet pipe 411, the plug body 431 has a hollow and penetrating fuel channel 433 along its own axial direction, and in this embodiment, the axial direction of the plug body 431 is the axial direction of the electronic atomization device. The through-column 432 is movably penetrated in the plug body 431 along the radial direction of the plug body 431, and the through-column 432 is provided with a through hole 434 along the axial direction of the plug body 431, wherein when the through hole 434 moves into the fuel channel 433, the air outlet pipe 411 is communicated with the fuel cavity 441, and when the through hole 434 is misplaced with the fuel channel 433, the through-column 434 blocks the fuel channel 433.

In this embodiment, the through-hole 432 makes a linear reciprocating motion in the radial direction of the plug body 431, so that the air outlet pipe 411 and the fuel cavity 441 are in a communicating state or in a non-communicating state. The radial direction of the plug 431 is a direction perpendicular to the axial direction of the electronic atomizing device, and specific reference may be made to the left-right direction indicated in fig. 2. When the air outlet pipe 411 and the fuel cavity 441 are in a mutually communicated state, the igniter 450 starts the ignition operation, and at the moment, the combustion of fuel can be realized at the combustion head 420; when the outlet pipe 411 is in a non-communication state with the fuel cavity 441, the igniter 450 is not started, and the combustion head 420 does not burn fuel.

Further, the electronic atomizing device further includes a control 700 (shown in fig. 2 and 3), and the control 700 is connected to the igniter 450 (shown in fig. 4 and 5) to control the igniter 450 to start the ignition operation or to shut down the ignition operation by the control 700. In this embodiment, the control member 700 is a control circuit board, and the control circuit board is provided with an ignition circuit, and the igniter 450 is connected to the ignition circuit. When the air outlet pipe 411 is communicated with the fuel cavity 441, the ignition circuit is in a passage state, and at the moment, the control circuit board controls the igniter 450 to start ignition operation; when the outlet pipe 411 is in a non-communication state with the fuel cavity 441, the ignition circuit is in an open state.

Further, as shown in fig. 10 to 12, the channel width of the communication between the through-hole 434 and the fuel channel 433 increases with an increase in the depth of insertion of the through-post 432 into the plug body 431 until the through-hole 434 is completely within the fuel channel 433. Wherein FIG. 10 shows the blocking of fuel channel 433 by through-column 432; fig. 11 shows that the through hole 434 communicates with the fuel channel 433 with a smaller channel width in communication; fig. 12 shows that the through hole 434 communicates with the fuel channel 433 with the maximum channel width. In the present embodiment, referring to fig. 10 to 12, the penetration post 432 is inserted into the plug body 431 to such a depth that the penetration post 432 moves toward the left side of the plug body 431 in the radial direction of the plug body 431, and the penetration hole 434 is located on the right side of the fuel passage 433. Thus, as the through-column 432 moves, the depth of the through-column 432 into which the plug body 431 is inserted gradually increases, and the channel width of communication between the through-hole 434 and the fuel channel 433 increases until the channel width of communication between the through-hole 434 and the fuel channel 433 is maximized when the through-hole 434 is completely located within the fuel channel 433.

In contrast to the above, when the through hole 434 is located on the left side of the fuel channel 433, that is, the through post 432 moves toward the right side of the plug body 431 in the radial direction of the plug body 431 (not shown). At this time, the channel width of the communication between the through-hole 434 and the fuel channel 433 increases with the distance from the through-post 432 to the plug 431 until the through-hole 434 is completely located in the fuel channel 433, which will not be described in detail herein.

Further, taking the movement of the through-column 432 toward the left side of the plug body 431 along the radial direction of the plug body 431 as an example, as shown in fig. 2, 4, 5, and 10 to 12, some structures of the present embodiment are designed, and the air regulating assembly 430 may further include an elastic member 435 and an adjusting knob 436. Wherein, an abutting block 4321 is provided at one end of the penetrating column 432, a threaded connection hole (not shown) is provided at one end of the penetrating column 432, the elastic member 435 is sleeved at one end of the penetrating column 432, one end of the elastic member 435 abuts against the outer sidewall of the plug body 431, and the other end of the elastic member 435 abuts against the abutting block 4321. The adjusting knob 436 is screwed into a threaded hole (not shown) of the through-column 432, and an end of the adjusting knob 436 remote from the through-column 432 is exposed out of the outer sidewall of the outer housing for driving the through-column 432 to move along the radial direction of the plug body 431.

In this embodiment, the adjustment knob 436 has two functions. The first function of the adjusting knob 436 is to drive the through-hole 432 to move toward the left side of the plug body 431 in the radial direction of the plug body 431 by pressing the adjusting knob 436, so that the through-hole 434 on the through-hole 432 is partially located in the fuel channel 433. At this time, although the through-hole 434 communicates with the fuel channel 433, the channel width communicating between the through-hole 434 and the fuel channel 433 is small, so that less fuel is conducted to the fuel cavity 441, resulting in weaker flames when the combustion head 420 burns fuel. Thus, in the present embodiment, the second function of the adjusting knob 436 is to rotate the adjusting knob 436, so that the through-column 432 can continue to move toward the left side of the plug body 431 in the radial direction of the plug body 431 until the through-hole 434 is completely located in the fuel channel 433, at which time the channel width communicating between the through-hole 434 and the fuel channel 433 is maximized.

The second function of the air adjusting knob 436 is achieved because the adjusting knob 436 is screwed to the threaded connection hole of the through-column 432, that is, the adjusting knob 436 can be regarded as a threaded push rod, so that the through-column 432 can be pushed to move along the radial direction of the plug body 431 when the adjusting knob 436 rotates. For example, when the adjusting knob 436 rotates clockwise, the through-hole 432 is pushed to move toward the left side of the plug body 432 in the radial direction of the plug body 431 to increase the channel width communicated between the through-hole 434 and the fuel channel 433, thereby increasing the flow rate of the fuel in the outlet pipe 110, that is, increasing the combustion fire of the burner head 420; when the adjusting knob 436 is rotated counterclockwise, the adjusting knob 436 is returned to the original position, and at this time, the penetrating column 432 is movable toward the right side of the plug body 432 in the radial direction of the plug body 431 to reduce the channel width communicating between the penetrating hole 434 and the fuel channel 433, thereby reducing the flow rate of the fuel in the outlet pipe 110, i.e., reducing the combustion fire of the burner head 420.

After the adjusting knob 436 is pressed, the elastic member 435 is compressed and stores elastic force by the pressing block 4321 and the plug 431, so that after the adjusting knob 436 is released, the penetrating column 432 returns to the initial position by the elastic force stored by the elastic member 435, and the penetrating hole 434 and the fuel channel 433 are dislocated, and at this time, the combustion head 420 is extinguished. In order to solve the above-mentioned drawbacks, as shown in fig. 13, the electronic atomization device in the present embodiment further includes a pressing ring 800, the pressing ring 800 may be disposed on the inner sidewall of the fire dividing cover 440 or the main housing 130, and the pressing ring 800 is sleeved on the periphery of the through post 432 and is disposed at a distance from the through post 432. At least one opening 810 is arranged on the pressing ring 800, at least one pressing protrusion 4323 is arranged on the periphery of the pressing block 4321 in a protruding mode, and the position of the pressing protrusion 4323 corresponds to the position of the opening 810.

Optionally, the outer diameter of the abutment block 4321 is smaller than the inner diameter of the abutment ring 800, and the size of the abutment protrusion 4323 is smaller than the size of the opening 810, so that the abutment block 4321 can pass through the gap between the abutment ring 800 and the through-column 432, and the abutment protrusion 4323 can pass through the opening 810. That is, when the adjustment knob 436 is pressed, the pressing block 4321 passes through the gap between the pressing ring 800 and the through-hole 432, and the pressing protrusion 4323 also passes through the position of the opening 810, and in this state, when the adjustment knob 436 is released, the pressing block 4321 and the pressing protrusion 4323 return to the initial positions by the elastic member 435, and the through-hole 432 blocks the fuel passage 433 and the burner head 420 to be extinguished. When the adjusting knob 436 is rotated after being pressed, the pressing protrusion 4323 presses against the pressing ring 800 (as shown in fig. 14), and at this time, the elastic member 435 is still in a continuously compressed state. When the adjusting knob 436 is rotated, the through-hole 432 is pushed to move toward the left side of the plug body 432 in the radial direction of the plug body 431, so that the channel width communicating between the through-hole 434 and the fuel channel 433 is gradually increased.

Further, in other structures designed in this embodiment, as shown in fig. 15, the air conditioning assembly 430 may further include an elastic member 435 and a rotating member 437. Wherein, an abutting block 4321 is provided at one end of the penetrating column 432, a threaded connection hole (not shown) is provided at one end of the penetrating column 432, the elastic member 435 is sleeved at one end of the penetrating column 432, one end of the elastic member 435 abuts against the outer sidewall of the plug body 431, and the other end of the elastic member 435 abuts against the abutting block 4321. The rotating member 437 is disposed in the outer housing 100, the rotating member 437 is screwed into the threaded connection hole of the through-hole 432, and an end of the rotating member 437 remote from the through-hole 432 is connected to the control member 700, and the control member 700 is used for controlling the rotating member 437 to rotate so that the through-hole 432 moves along the radial direction of the plug body 431.

Alternatively, the elastic member 435 may be a member having good elastic properties such as a spring, a shrapnel, an elastic band, etc., which is not particularly limited in this embodiment.

In this embodiment, the rotation member 437 is preferably a motor, the output end of the motor is screwed on the through-column 432, at this time, the rotation of the motor can be controlled by the control member 700, and the motor drives the through-column 432 to make a linear motion along the radial direction of the plug body 431 when rotating, so as to achieve the same technical effect as that achieved by rotating the adjustment knob 436 in the above embodiment, which is specifically described with reference to the above embodiment, and will not be repeated herein.

Further, as shown in fig. 2, 3 and 5, the electronic atomizing apparatus further includes a first temperature detector 900, a second temperature detector 1000 and a display 1100, where the first temperature detector 900 is connected to the control member 700, and the first temperature detector 900 is disposed on a side of the burner head 420 away from the fuel cavity 441, for detecting a combustion temperature when the burner head 420 burns. The second temperature detector 1000 is connected to the control member 700, and the second temperature detector 1000 is provided at an end of the pipe 320 extending to the material container 200 for detecting a temperature at the end of the pipe 320 extending to the material container 200, i.e., an outlet temperature of the pipe 320. The display 1100 is connected to the control member 700 and exposed to the outer sidewall of the outer case 100, and the display 1100 is used for displaying the temperature values detected by the first temperature detector 900 and the second temperature detector 1000.

In practical applications, taking the gas adjusting assembly 430 as an example, the gas adjusting assembly 436 includes an adjusting knob 436, the through hole 434 and the fuel channel 433 are communicated with each other by pressing the adjusting knob 436, and at this time, the ignition circuit is in a passage state, that is, the igniter 450 starts the ignition operation, so that the burner 420 is in a burning state. The adjusting knob 436 is rotated again to adjust the channel width of the communication between the through hole 434 and the fuel channel 433, and observe the temperature in the display 1100, that is, the combustion temperature of the burner head 420 detected by the first temperature detector 900 and the outlet temperature of the pipe 320 detected by the second temperature detector 1000. Finally, the adjustment knob 436 is rotated to adjust the outlet temperature of the conduit 320 to the desired atomization temperature (e.g., 310 ℃).

Optionally, as shown in fig. 3, 5 and 15, the electronic atomizing device further includes a battery 1200, and the battery 1200 is connected to the control member 700 for supplying power to the control member 700, so as to ensure the normal operation of the control member 700.
