Description

Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to an electronic atomization device. Background Technology

[0002] A heated non-combustible atomizing device is an electronic atomizing device that heats and atomizes the material to be atomized at low temperature without combustion, thereby forming a smoke-producing mist.

[0003] In existing heated tobacco products (HTPs), the atomized substance is generally an herbal product. This herbal product mainly consists of a filter and the herbal material connected to it, and is cylindrical in shape. During use, the herbal product is inserted directly into the heating chamber of the HTP, with the filter exposed. The heater is then activated to heat and atomize the substance, producing smoke, which the user can then inhale. Some HTPs are made from dried tobacco leaves; the use of these is permitted within legally defined countries and regions for relieving stress and fatigue.

[0004] However, existing heat-not-burn atomizing devices typically use the main unit's power supply as the heater. This means that after the heater is powered on, it heats the outside air and conducts the heated air into the heating chamber, where the herbal substances are atomized to produce smoke. While this type of heater, powered by the main unit, is simple and convenient to use, its application is always limited. For example, if there is no power source available outdoors and the main unit's remaining power is insufficient to start the heater, it cannot be used. Or, in extreme temperatures, the electronic atomizing device may malfunction, causing the main unit's power supply to also fail, rendering the heater unusable. Summary of the Invention

[0005] The purpose of this invention is to provide an electronic atomizing device that addresses the technical problem that existing electronic atomizing devices have limited application scenarios for their heaters, making them unable to be started and used outdoors without power or in extreme temperatures, thus causing the electronic atomizing device to malfunction.

[0022] In some embodiments, the electronic atomizing device further includes a control element connected to the igniter.

[0023] In some embodiments, the width of the channel connecting the through hole and the fuel passage increases as the depth of the through post inserted into the plug increases, until the through hole is completely within the fuel passage.

[0024] In some embodiments, one end of the through-post is provided with an abutment block, and one end of the through-post is provided with a threaded connection hole; the air regulating assembly further includes:

The fuel heater includes a fuel canister for holding fuel and a burner head connected to the fuel canister. The burner head is located in a combustion chamber formed at the end of the heat sink furthest from the material container, allowing the fuel head to heat the heat sink by burning fuel in the fuel canister. The heat generated by the heated heat sink is then conducted to the air in the pipe, heating the air within the pipe. This heated air is then conducted to the material container, thereby heating and atomizing the herbal substances within the container. In other words, the burner head heats the heat sink by burning fuel in the fuel canister, and the heat generated by the heated heat sink is conducted to the material container to heat and atomize the herbal substances.

[0075] Please refer to Figure 1-15 This invention provides an electronic atomizing device for heating and atomizing low-temperature non-combustible herbal substances.

[0076] Combination Figures 1 to 5 As shown, the electronic atomizing device includes a housing 100, a material container 200, a heat exchanger 300, and a fuel heater 400. The housing 100 has at least one air inlet 110 and at least one exhaust outlet 120. The material container 200 is connected to the housing 100 and is used to hold herbal substances. The heat exchanger 300 is located inside the housing 100 and below the material container 200. The heat exchanger 300 includes a heat sink 310 and a pipe 320 connected to the heat sink 310. One end of the pipe 320 is connected to the air inlet 110, and the other end extends into the material container 200. The air inlet 110 is used to conduct outside air into the pipe 320. A combustion chamber 330 is formed at the end of the heat sink 310 away from the material container 200. The combustion chamber 330 is connected to the exhaust port 120, which is used to discharge the exhaust gas after combustion in the combustion chamber 330. The exhaust gas includes, but is not limited to, carbon dioxide and carbon monoxide. A fuel heater 400 is disposed inside the outer casing 100. The fuel heater 400 includes a fuel tank 410 for holding fuel and a burner head 420 connected to the fuel tank 410. The burner head 420 is located inside the combustion chamber 330. The burner head 420 is used to burn the fuel in the fuel tank 410 and heat the heat sink 310, so that the heat from the heat sink 310 is conducted to the air in the pipe 320, and the heated air is conducted to the material container 200 to heat and atomize the herbal material.

[0077] The aforementioned herbal substances can be low-temperature non-combustible tobacco products or other types of aerosol-generating products, such as tobacco leaves and shredded tobacco, depending on the user's actual needs. This embodiment does not impose specific limitations on this.

[0078] In this embodiment, the aforementioned herbal substance is preferably a low-temperature non-combustible tobacco product. Low-temperature non-combustible tobacco products mainly refer to aerosol-generating products made from materials such as tobacco shreds, tobacco particles, plant fragments, tobacco flavorings, and propylene glycol. Their shape is generally cylindrical (e.g., cylindrical), hence the name low-temperature non-combustible cigarette. Under low-temperature heating conditions, the nicotine and other aromatic volatile substances inside can evaporate without producing solid particles, only generating atomized vapor. It can be understood that the low temperature here refers to the temperature at which the herbal substance can generate an aerosol without combustion, and this temperature is generally between 200℃ and 400℃.

[0079] In this embodiment, the heat sink 310 and the pipe 320 can be metal components, as metal components have better thermal conductivity. For example, the heat sink 310 and the pipe 320 can be made of at least one material such as copper, aluminum, nickel-chromium alloy, iron-chromium-aluminum, or stainless steel. It should be noted that the heat sink 310 and the pipe 320 can be made of the same material, for example, both the heat sink 310 and the pipe 320 can be made of stainless steel; or, the heat sink 310 and the pipe 320 can be made of different materials, for example, the heat sink 310 can be made of stainless steel and the pipe 320 can be made of aluminum. This is not a limitation.

[0080] In this embodiment, the heat exchanger 300 is located below the material container 200, the combustion chamber 330 is located at the end of the heat sink 310 away from the material container 200, and the burner head 420 of the fuel heater 400 is located inside the combustion chamber 330, that is, the combustion chamber 330 is located between the heat sink 310 and the fuel heater 400. Thus, in order to save internal space in the outer casing 100, combined with... Figure 2As shown, the heat exchanger 300 and the fuel heater 400 are arranged sequentially from top to bottom within the outer casing 100. The material container 200 is located at the upper end outside the outer casing 100, and the fuel heater 400 is located at the lower end inside the outer casing 100. The heat exchanger 300 is positioned between the material container 100 and the fuel heater 400, so that the burner head 420 of the fuel heater 400 burns the fuel in the fuel tank 410, thereby heating the heat sink 310. The heat generated by the heat sink 310 is then conducted to the connected pipe 320, heating the air entering the pipe 320. Since the other end of the pipe 320 extends into the material container 200 and communicates with its interior space, the heated air in the pipe 320 can be conducted into the material container 200, heating and atomizing the herbal material within it.

[0081] It should be noted that the positions of the heat exchanger 300 and the fuel heater 400 within the housing 100 do not need to be set as described above. They can also be set in other ways, such as: the combustion chamber 330 is set on the left or right side of the heat sink 310 (not shown). In this case, the fuel heater 400 can be set side by side with the heat exchanger 300, and the burner head 420 of the fuel heater 400 is still set in the combustion chamber 330, etc. There are no restrictions here.

[0082] The technical solution provided by the present invention involves sequentially arranging a heat exchanger 300 and a fuel heater 400 within the outer casing 100. The heat exchanger 300 includes a heat sink 310 and a pipe 320 connected to the heat sink 310. One end of the pipe 320 is connected to an air inlet 110, and the other end is connected to a material container 200. The fuel heater 400 includes a fuel tank 410 for holding fuel and a burner head 420 connected to the fuel tank 410. The burner head 420 is located within a combustion chamber 330 formed at the end of the heat sink 310 away from the material container 200, allowing the fuel head 420 to heat the heat sink 310 by burning the fuel in the fuel tank 410. The heat generated by the heat sink 310 after heating can be conducted to the air in the pipe 320, heating the air in the pipe 320. The heated air is then conducted to the material container 200, thereby achieving the heating and atomization of the herbal substances in the material container 200. Specifically, the fuel in the fuel canister 410 is heated by the burner head 420, which in turn heats the heat exchanger 310. The heat generated by the heat exchanger 310 is then conducted to the material container 200, atomizing the herbal material. In this way, the fuel heater 400 provides heat to the heat exchanger 300 by burning fuel through the burner head 420, without relying on the main unit's power supply. This allows the fuel heater 400 to operate outdoors in environments without power or in extreme temperatures, improving the applicability of the electronic atomization device. Furthermore, since this electronic atomization device does not rely on the main unit's power supply, it reduces the main unit's energy consumption, extends its battery life, and thus increases its operating time and lifespan.

[0083] Furthermore, combined Figure 2 , 3 As shown in Figure 5, the material container 200 includes a container body 210 and a receiving chamber 220 connected to the container body 210. The container body 210 is connected to the top of the outer shell 100. The receiving chamber 220 has a receiving cavity 221 for receiving herbal substances. At least one air hole 223 is provided at the bottom of the receiving chamber 220, which extends into the receiving cavity 220. The air hole 223 is used to connect the receiving cavity 221 to the pipe 320, so that the heated air in the pipe 320 is conducted to the receiving cavity 221 through the air hole 223, thereby realizing the heating and atomization of the herbal substances in the receiving cavity 221.

[0084] In order to facilitate the insertion or placement of tobacco products made of herbal substances into the receiving cavity 221, the shape of the receiving cavity 221 in this embodiment is matched with the tobacco products made of herbal substances, for example, it can be set as a column, etc., and is not limited here.

[0085] In this embodiment, the hot air outlet of the pipe 320 is positioned opposite to the bottom of the receiving chamber 220, meaning the hot air outlet of the pipe 320 is opposite to the air vent 223. This design of the air vent 223 serves two purposes. First, it conducts the heated air from the pipe 320 to the receiving chamber 221, where the hot air heats and atomizes the herbal material. Second, since one end of the pipe 320 is directly connected to the air inlet 110, outside air may contain dust or other floating particles when it is conducted from the air inlet 110 to the pipe 320. The other purpose of the air vent 223 is to filter out dust or other floating particles even if they are present in the pipe 320, thus preventing the smoke from containing these particles and improving the user's inhalation experience.

[0086] It should be noted that the number of vents 223 is preferably multiple, so that more hot air in the pipe 320 can be conducted into the receiving cavity 221. The arrangement and specific number of vents 223 can be set according to actual needs and are not limited here.

[0087] Optionally, the container body 210 and the receiving chamber 220 are an integral structure.

[0088] Furthermore, combined Figure 6 and Figure 7 As shown, the heat sink 310 is generally cylindrical, with multiple heat sinks 311 distributed along its circumference. Adjacent heat sinks 311 are spaced apart, and a pipe 320 is spirally wound around the outer circumference of the heat sink 310. Here, the spaced-apart arrangement of the adjacent heat sinks 311 is such that one end of the multiple heat sinks 311 is connected to the central axis of the heat sink 310, and the adjacent heat sinks 311 are arranged at an angle, so that the other ends of the multiple heat sinks 311 are spaced apart.

[0089] In this embodiment, the pipe 320 can be spirally embedded around the outer periphery of the heat sink 311 along the circumference of the heat sink 310 (e.g., Figure 2 and Figure 3 As shown in the diagram, this ensures complete contact between the heat sink 311 and all parts of the pipe 320, thereby transferring more of the heat generated by the heat sink 311 to the pipe 320 via thermal conduction, resulting in faster and more uniform heating of the air within the pipe 320. It should be noted that both the end of the pipe 320 near the air inlet 110 and the end near the material container 200 need to extend from the outer periphery of the heat sink 311 to connect the air inlet 110 and the material container 200.

[0090] Alternatively, the pipe 320 can also be spirally laid around the outer periphery of the heat sink 311 (not shown) along the circumference of the heat sink 310, so that more of the heat generated after the heat sink 311 is heated can be conducted to the pipe 320 by heat conduction, thereby achieving the effect of heating the air inside the pipe 320.

[0091] In this embodiment, a combustion chamber 330 is formed at the end of the heat sink 310 away from the material container 200. In some structural designs of this embodiment, the combustion chamber 330 can be configured in two ways.

[0092] Specifically, in one configuration of the combustion chamber 330, each heat dissipation plate 311 is enclosed at the end furthest from the material container 200 to form a combustion chamber 330 with a cavity (e.g., Figures 2 to 4 (As shown). Combined Figures 2 to 4 As shown in Figures 8 and 9, the heat dissipation plate 311 includes a connecting portion 3110 and an extension portion 3112 connected to the connecting portion 3110. The extension portion 3112 is located at the end of the connecting portion 3110 away from the material container 200, that is, the extension portion 3112 is located below the connecting portion 3110. Each heat dissipation plate 311's connecting portion 3110 is used to connect with the connecting portions 3110 of other heat dissipation plates 3111. Each extension portion 3112 has a notch 3113 facing the central axis of the heat dissipation component 310. The notches 3113 on the extension portions 3112 of all heat dissipation plates 310 together form a cavity, which is the aforementioned combustion chamber 330. Thus, when the burner head 420 burns fuel within the combustion chamber 330, more of the heat generated by the burner head 420 can be dissipated onto the heat dissipation plate 311, resulting in more uniform heating of the heat dissipation plate 311. In addition, the adjacent heat sinks 311 are spaced apart, and the gaps formed can be used to conduct the exhaust gas generated by the combustion of fuel in the combustion chamber 330 by the burner head 420 to the exhaust gas outlet 120, so that the exhaust gas is discharged from the exhaust gas outlet 120 to the outside of the electronic atomizing device.

[0093] Furthermore, the shape of the notch 3113 is arc-shaped (e.g., Figure 8 As shown), the combustion chamber 330 formed by the arc-shaped notch 3113 is dome-shaped; or, the notch 3113 can also be square, and the combustion chamber 330 formed by the square notch 3113 is square (as shown). Figure 9 (As shown). Of course, it should be noted that the shape of the notch 3113 is not limited to the arc or square shape mentioned above, but can also be a triangle, trapezoid, or a combination of two or more shapes, which is not limited here.

[0094] A second configuration of the combustion chamber 330 involves a cavity-containing combustion chamber 330 (not shown) located outside the end of each heat sink 311 furthest from the material container 200. Specifically, this combustion chamber 330 is a combustion chamber structure with a cavity between the heat sink 311 and the fuel tank 410, such as a combustion chamber or combustion chamber. In this case, the combustion chamber 330 and the heat sink 311 are in contact, allowing the heat generated by the combustion of fuel by the burner head 420 within the combustion chamber 330 to be conducted to the heat sink 311 for heat dissipation. Furthermore, the combustion chamber 330 is connected to the gap formed between adjacent heat sinks 311, allowing the exhaust gas generated by the combustion of fuel by the burner head 420 within the combustion chamber 330 to be conducted through the gap between adjacent heat sinks 311 to the exhaust port 120, thereby discharging the exhaust gas from the exhaust port 120 to the outside of the electronic atomizing device.

[0095] Furthermore, the exhaust port 120 is disposed on the side wall of the outer casing 100 corresponding to the area where the heat sink 311 is located, or the exhaust port 120 is disposed on the side wall above the area of ​​the outer casing 100 corresponding to the area where the heat sink 311 is located, so that the exhaust gas in the combustion chamber 330 can be discharged to the outside of the electronic atomizing device through the gap between the heat sinks 311 and the exhaust port 120.

[0096] In this embodiment, the exhaust port 120 is disposed on the side wall above the area of ​​the heat sink 311 of the outer casing 100. The outer casing 100 includes a main casing 130 and an exhaust seat 140 disposed on the upper end of the main casing 130. The exhaust port 120 is disposed on the outer peripheral wall of the exhaust seat 140.

[0097] Specifically, the heat exchanger 300 and the fuel heater 400 are arranged sequentially from top to bottom inside the main housing 130. The air inlet 110 is opened on the main housing 130 and is located in the area between the heat exchanger 300 and the fuel heater 400, that is, the air inlet 110 is located below the heat exchanger 300. This allows the pipe 320 to contact more heat dissipation plates 311 when one end of the pipe 320 is connected to the air inlet 110 and the other end of the pipe 320 is spirally wound around the outer periphery of the heat sink 310, thereby making the air in the pipe 320 heat up faster and more evenly.

[0098] like Figure 2 , 3 As shown in Figure 5, the exhaust gas outlet 140 is located at one end of the main housing 130 near the heat exchanger 300, and the exhaust gas outlet 140 has a hollow through-hole 141 along the axial direction of the electronic atomizing device. The other end of the pipe 320 is connected to the hollow through-hole 141, and the hollow through-hole 141 is connected to the space inside the material container 200. The hollow through-hole 141 is connected to the space inside the material container 200 through the air hole 223 (…). Figure 2 It is connected to the receiving chamber 220 in the material container 200 so that the hot air in the pipe 320 can be conducted to the receiving chamber 220 through the air hole 223 to heat and atomize the herbal material in the receiving cavity 221 of the receiving chamber 220.

[0099] Optionally, the exhaust port 120 is provided on the outer peripheral wall of the exhaust port 140, and the exhaust port 120 is connected to the combustion chamber 330 through the gap formed between adjacent heat dissipation plates 311.

[0100] In this embodiment, the main housing 130 and the exhaust gas seat 140 can be an integral structure. The material container 200 and the main housing 130 can also be an integral structure, or the material container 200 and the main housing 130 can be separate structures.

[0101] Furthermore, the material container 200 and the main shell 130 are preferably separate structures, meaning that the material container 200 and the main shell 130 are connected in a detachable manner. To achieve the connection between the material container 200 and the main shell 130, such as... Figure 2 , 3 As shown in Figure 5, the aforementioned electronic atomizing device may further include an upper sleeve 500, which is fitted onto the exhaust gas seat 140, and the material container 200 is disposed within the upper sleeve 500 and connected to the hollow hole 141. That is, the upper sleeve 500 is connected to the exhaust gas seat 140 of the outer shell 100, and the material container 200 is connected to the upper sleeve 500, thereby achieving interconnection between the material container 200, the upper sleeve 500, and the outer shell 100. It should be noted that the interconnection between the material container 200, the upper sleeve 500, and the outer shell 100 is a detachable connection.

[0102] Since the material container 200 is fitted inside the upper sleeve 500, the receiving chamber 220 is located within the space of the upper sleeve 500. At this time, a gap space is formed between the outer wall of the receiving chamber 220 and the inner wall of the upper sleeve 500. The other end of the pipe 320 is connected to the hollow hole 141 of the exhaust gas outlet 140. Thus, some of the hot air from the pipe 320 is conducted into the gap space formed between the receiving chamber 220 and the upper sleeve 500, resulting in a reduction in the amount of hot air conducted into the receiving chamber 220. Therefore, the electronic atomizing device in this embodiment also includes a heat insulation component 600, which is disposed between the outer wall of the material container 200 and the inner wall of the upper sleeve 500, and is spaced apart from both the outer wall of the material container 200 and the inner wall of the upper sleeve 500. At this time, a heat-conducting space 610 is formed between the outer wall of the receiving chamber 220 and the insulation component 600. This heat-conducting space 610 can accommodate some of the hot air conducted from the pipe 320. The hot air in the heat-conducting space 610 can be conducted to the side wall of the receiving cavity 221 through the side wall of the receiving chamber 220, thereby heating and / or preheating the side of the herbal material. An air hole 223 is provided at the bottom of the receiving chamber 220. Most of the hot air in the pipe 320 will be conducted to the receiving cavity 221 through the air hole 223, thereby heating and atomizing the herbal material from the bottom. Thus, through the hot air conducted to the heat-conducting space 610 and the hot air at the bottom of the receiving cavity 221, the atomization of the herbal material is more complete and the atomization efficiency is higher.

[0103] Furthermore, such as Figure 1 , 2 As shown in Figures 4 and 5, an observation hole 150 is provided on the outer periphery of the main housing 130. The observation hole 150 is positioned opposite to the combustion chamber 330 so that the combustion of the burner head 420 in the combustion chamber 330 can be directly observed through the observation hole 150.

[0104] Based on the above embodiments, combined with Figures 2 to 4 ,and Figure 10As shown, the fuel heater 400 also includes an air regulating assembly 430 (the components included in the air regulating assembly 430 are described later in this paragraph), a distributor cap 440, and an igniter 450. The fuel tank 410 has an outlet pipe 411 located at the end near the heat sink 310. The air regulating assembly 430 is fitted onto the outlet pipe 411 and is used to adjust the flow rate of fuel passing through the outlet pipe 411. The burner cap 440 is located inside the combustion chamber 330 and is sealed to the gas regulating assembly 430. A fuel chamber 441 is provided at one end of the burner cap 440 near the gas regulating assembly 430, and at least one burner head 420 is provided at the other end of the burner cap 440 away from the gas regulating assembly 430. Each burner head 420 has a fuel through hole 442 that extends through to the fuel chamber 441. An igniter 450 is located on the side of the burner head 420 away from the fuel chamber 441, so that the fuel stored in the fuel tank 410 is conducted to the fuel chamber 441 through the gas outlet pipe 411, and then to the fuel head 420 through the fuel through hole 442, where it is ignited by the igniter 450, thereby enabling the fuel to burn at the burner head 420.

[0105] It should be noted that the above description is based on the premise that the gas regulating component 430 connects the gas outlet pipe 411 and the fuel chamber 441, so that the fuel in the fuel tank 410 can be supplied to the burner head 420 through the gas outlet pipe 411, the fuel chamber 441 and the fuel through hole 442, and then burned after the igniter 450 starts the ignition operation.

[0106] Furthermore, multiple burner heads 420 are preferably distributed evenly within the combustion chamber 330, so that the heat generated by the combustion of fuel by the multiple burner heads 420 can evenly heat the heat dissipation plate 311. The arrangement and specific number of burner heads 420 can be set according to actual needs and are not limited here. An air filling hole 4102 is provided at the bottom of the fuel tank 410. The air filling hole 4102 is used to connect an external air filling device to fill the fuel tank 410 with fuel.

[0107] Specifically, the air regulating assembly 430 includes a plug 431 and a through-post 432. The plug 431 is sleeved on the outer wall of the air outlet pipe 411. The plug 431 has a hollow, through-flow fuel channel 433 along its own axial direction. In this embodiment, the axial direction of the plug 431 is the axial direction of the electronic atomizing device. The through-post 432 is movably inserted through the plug 431 radially, and the through-post 432 has a through hole 434 along the axial direction of the plug 431. When the through hole 434 moves into the fuel channel 433, the air outlet pipe 411 is connected to the fuel chamber 441. When the through hole 434 is misaligned with the fuel channel 433, the through-post 434 blocks the fuel channel 433.

[0108] In this embodiment, by having the through-post 432 reciprocate linearly in the radial direction of the plug 431, the air outlet 411 and the fuel chamber 441 can be either in a connected or disconnected state. The radial direction of the plug 431 is perpendicular to the axial direction of the electronic atomizing device; see reference [link to relevant documentation] for details. Figure 2 The left and right directions are indicated by the center mark. When the exhaust pipe 411 and the fuel chamber 441 are in a state of mutual connection, the igniter 450 starts the ignition operation, and the fuel can be burned at the burner head 420. When the exhaust pipe 411 and the fuel chamber 441 are not in a state of mutual connection, the igniter 450 does not start, and there is no fuel combustion at the burner head 420.

[0109] Furthermore, the electronic atomizing device also includes a control element 700 (such as...). Figure 2 and 3 As shown), control unit 700 and igniter 450 (as shown) Figure 4 and 5 The igniter 450 is connected to the control circuit (shown) to control the igniter 450 to initiate or deactivate the ignition operation. In this embodiment, the control circuit 700 is a control circuit board, which has an ignition circuit. The igniter 450 is connected to the ignition circuit. When the exhaust pipe 411 is connected to the fuel chamber 441, the ignition circuit is in a closed state, and the control circuit board controls the igniter 450 to initiate the ignition operation. When the exhaust pipe 411 and the fuel chamber 441 are not connected, the ignition circuit is in an open state.

[0110] Furthermore, such as Figures 10 to 12 As shown, the width of the channel connecting the through hole 434 and the fuel passage 433 increases with the depth of the through post 432 inserted into the plug 431, until the through hole 434 is completely within the fuel passage 433. Wherein, Figure 10 This shows that the through-post 432 blocks the fuel passage 433; Figure 11 It is shown that the through hole 434 and the fuel passage 433 are interconnected and the width of the interconnected passage is relatively small; Figure 12 This shows that the through hole 434 and the fuel passage 433 are interconnected, and the width of the interconnected passage is the largest. In this embodiment, refer to... Figures 10 to 12 The depth to which the penetrating post 432 is inserted into the plug body 431 is such that the penetrating post 432 moves radially towards the left side of the plug body 431, while the penetrating hole 434 is located on the right side of the fuel passage 433. Thus, as the penetrating post 432 moves, the depth to which it is inserted into the plug body 431 gradually increases, and the width of the channel connecting the penetrating hole 434 and the fuel passage 433 also increases, until the penetrating hole 434 is completely located within the fuel passage 433, at which point the width of the channel connecting the penetrating hole 434 and the fuel passage 433 reaches its maximum.

[0111] It should be noted that, contrary to the above, when the through hole 434 is on the left side of the fuel passage 433, that is, when the through post 432 moves radially towards the right side of the plug body 431 (not shown), the width of the channel connecting the through hole 434 and the fuel passage 433 increases as the distance the through post 432 is pulled out of the plug body 431 increases, until the through hole 434 is completely within the fuel passage 433, which will not be elaborated here.

[0112] Furthermore, taking the movement of the through-post 432 radially toward the left side of the plug body 431 as an example, some structures designed in this embodiment, such as... Figure 2 , 4 As shown in Figures 5, 10 to 12, the air regulating assembly 430 may further include an elastic element 435 and an adjusting knob 436. One end of the through-post 432 is provided with an abutment block 4321, and one end of the through-post 432 has a threaded connection hole (not shown). The elastic element 435 is sleeved on one end of the through-post 432, with one end of the elastic element 435 abutting against the outer wall of the plug body 431, and the other end of the elastic element 435 abutting against the abutment block 4321. The adjusting knob 436 is threaded into the threaded connection hole (not shown) of the through-post 432, and the end of the adjusting knob 436 away from the through-post 432 protrudes from the outer wall of the outer casing, used to drive the through-post 432 to move radially along the plug body 431.

[0113] In this embodiment, the adjustment knob 436 has two functions. The first function of the adjustment knob 436 is that by pressing the adjustment knob 436, the through-post 432 can be moved radially towards the left side of the plug body 431, so that the through hole 434 on the through-post 432 is partially located within the fuel channel 433. At this time, although the through hole 434 is connected to the fuel channel 433, the width of the channel connecting the through hole 434 and the fuel channel 433 is small, resulting in less fuel being conducted to the fuel chamber 441, leading to a weaker flame when the burner head 420 burns the fuel. Therefore, in this embodiment, the second function of the adjustment knob 436 is that by rotating the adjustment knob 436, the through-post 432 can continue to move radially towards the left side of the plug body 431 until the through hole 434 is completely located within the fuel channel 433. At this time, the width of the channel connecting the through hole 434 and the fuel channel 433 is at its maximum.

[0114] The second function of the aforementioned air adjustment knob 436 is achieved because the adjustment knob 436 is threadedly connected to the threaded connection hole on the through post 432. That is, the adjustment knob 436 can be regarded as a threaded push rod, so that when the adjustment knob 436 is rotated, it can push the through post 432 to move radially along the plug body 431. For example, when the adjusting knob 436 is rotated clockwise, it pushes the through-bolt 432 to move radially toward the left side of the plug body 431, thereby increasing the width of the channel connecting the through hole 434 and the fuel passage 433, thus increasing the fuel flow rate in the exhaust pipe 110, i.e., increasing the combustion power of the burner head 420; when the adjusting knob 436 is rotated counterclockwise, it returns to its initial position. At this time, the through-bolt 432 can move radially toward the right side of the plug body 431, thereby decreasing the width of the channel connecting the through hole 434 and the fuel passage 433, thus decreasing the fuel flow rate in the exhaust pipe 110, i.e., decreasing the combustion power of the burner head 420.

[0115] After pressing the adjustment knob 436, the elastic element 435 is compressed and accumulates elastic force under the action of the pressing block 4321 and the plug 431. This causes the through post 432 to return to its initial position under the accumulated elastic force of the elastic element 435 after the adjustment knob 436 is released. This misaligns the through hole 434 with the fuel passage 433, at which point the burner head 420 is extinguished. To address the aforementioned defects, such as... Figure 13 As shown, in this embodiment, the electronic atomizing device also includes a pressure ring 800. The pressure ring 800 can be disposed on the inner side wall of the flame spreader 440 or the main housing 130, and the pressure ring 800 is sleeved on the outer periphery of the through post 432 and spaced apart from the through post 432. The pressure ring 800 is provided with at least one opening 810, and the outer periphery of the pressure block 4321 is provided with at least one pressure protrusion 4323, the position of the pressure protrusion 4323 corresponding to the position of the opening 810.

[0116] Optionally, the outer diameter of the pressing block 4321 is smaller than the inner diameter of the pressing ring 800, and the size of the pressing protrusion 4323 is smaller than the size of the opening 810, so that the pressing block 4321 can pass through the gap between the pressing ring 800 and the through post 432, and the pressing protrusion 4323 can pass through the opening 810. That is, when the adjusting knob 436 is pressed, the pressing block 4321 passes through the gap between the pressing ring 800 and the through post 432, and the pressing protrusion 4323 also passes through the opening 810. In this state, if the adjusting knob 436 is released, the pressing block 4321 and the pressing protrusion 4323 will return to their initial positions under the action of the elastic element 435, causing the through post 432 to block the fuel passage 433 and the burner head 420 to extinguish. If the adjusting knob 436 is pressed and then rotated, the pressing protrusion 4323 will press against the pressing ring 800 (e.g., Figure 14As shown in the diagram, at this time, the elastic element 435 is still in a state of continuous compression. When the adjusting knob 436 is rotated, it can push the through post 432 to move radially towards the left side of the plug body 431, thereby gradually increasing the width of the channel connecting the through hole 434 and the fuel passage 433.

[0117] Furthermore, in other structures designed in this embodiment, such as Figure 15 As shown, the air regulating assembly 430 may further include an elastic element 435 and a rotating element 437. One end of the through-post 432 is provided with an abutment block 4321, and one end of the through-post 432 has a threaded connection hole (not shown). The elastic element 435 is sleeved on one end of the through-post 432, and one end of the elastic element 435 abuts against the outer wall of the plug body 431, while the other end of the elastic element 435 abuts against the abutment block 4321. The rotating element 437 is disposed within the outer casing 100, and the rotating element 437 is threadedly connected to the threaded connection hole of the through-post 432. The end of the rotating element 437 away from the through-post 432 is connected to the control element 700, which controls the rotation of the rotating element 437 to cause the through-post 432 to move radially along the plug body 431.

[0118] Optionally, the elastic element 435 can be a spring, sheet, rubber band, or other element with good elastic properties. This embodiment does not impose specific limitations on this.

[0119] In this embodiment, the rotating component 437 is preferably a motor, and the output end of the motor is threadedly connected to the through column 432. At this time, the rotation of the motor can be controlled by the control component 700. When the motor rotates, it pushes the through column 432 to move linearly along the radial direction of the plug body 431. The effect achieved is the same as the technical effect achieved by rotating the adjustment knob 436 in the above embodiment. For details, please refer to the description of the above embodiment, which will not be repeated here.

[0120] Furthermore, combined Figure 2 , 3As shown in Figure 5, the electronic atomizing device also includes a first temperature detector 900, a second temperature detector 1000, and a display 1100. The first temperature detector 900 is connected to the control unit 700 and is located on the side of the burner head 420 away from the fuel chamber 441, used to detect the combustion temperature of the burner head 420 during combustion. The second temperature detector 1000 is connected to the control unit 700 and is located at one end of the pipe 320 extending to the material container 200, used to detect the temperature at that end of the pipe 320 extending to the material container 200, i.e., the outlet temperature of the pipe 320. The display 1100 is connected to the control unit 700 and is exposed on the outer wall of the housing 100, used to display the temperature values ​​detected by the first temperature detector 900 and the second temperature detector 1000.

[0121] In practical applications, taking the air conditioning assembly 430 including the adjustment knob 436 as an example, pressing the adjustment knob 436 connects the through hole 434 and the fuel passage 433. At this time, the ignition circuit is in a closed state, that is, the igniter 450 initiates the ignition operation, causing the burner head 420 to be in combustion. Then, rotating the adjustment knob 436 adjusts the width of the connection between the through hole 434 and the fuel passage 433, and the temperature displayed on the display 1100 is observed, namely 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, according to the desired atomization temperature (e.g., 310℃), rotating the adjustment knob 436 adjusts the outlet temperature of the pipe 320 to the desired atomization temperature.

[0122] Optionally, such as Figure 3 , 5 As shown in Figure 15, the electronic atomizing device also includes a battery 1200, which is connected to the control unit 700 to supply power to the control unit 700 and ensure its normal operation. Thus, the battery 1200 only needs to supply power to the ignition circuit and display 1100 on the control unit 700, thereby increasing the battery's battery life and allowing it to be used for a longer period, saving energy.

[0123] It should be noted that, as Figures 1 to 3 As shown in Figures 5 and 15, the electronic atomizing device also includes a charging port 1300 disposed on the main housing 130. The charging port 1300 is connected to the control unit 700 and is used to connect an external power supply device to charge the battery 1200.

[0124] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
