Description

High atomization efficiency heat-not-burn atomization device and atomization method Technical Field

[0001] The present disclosure relates to the technical field of heat-not-burn atomization devices, and in particular to a heat-not-burn atomization device with high atomization efficiency and an atomization method. Background Art

[0002] Heat-not-burn atomizers, also known as electronic atomizers, are named because they heat without burning. Currently, the mainstream heat-not-burn atomizers are primarily baking-type devices, which heat the atomized medium to produce inhalable smoke. These heat-not-burn atomizers can replace traditional cigarettes.

[0003] In related technologies, such as CN114145498A-removal device and heat-not-burn atomization device, when a smoker draws on the upper end of the heat-not-burn atomization device, i.e., the mouthpiece, the heat source heats the container, and at the same time, external air enters the container atomization slot of the container, causing the smoking material to produce smoke after being baked.

[0004] However, since external air needs to enter the atomizing tank to form smoke, the efficiency of generating smoke is low, and in the process of external air entering the atomizing tank, part of the heat will be wasted, resulting in low heat utilization rate.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a heat-not-burn atomization device and an atomization method with high atomization efficiency.

[0007] The purpose of this disclosure is achieved through the following technical solutions:

[0015] In one embodiment, the high atomization efficiency heat-not-burn atomization device further includes a heating stove connected to the heat source.

[0016] In one embodiment, the heating stove includes a carrier and a heat conductor, the carrier is provided with a carrier hole, the heat conductor is located in the carrier hole and connected to the carrier, and the heat conductor is sleeved on the heat source.

[0017] In one embodiment, the heat-not-burn atomizing device with high atomization efficiency further includes a suction cover assembly, wherein the suction cover assembly forms a suction air duct, and the suction air duct is connected to the opening of the atomizing tank.

[0019] An atomization method, using the high-efficiency heat-not-burn atomization device described in any of the above embodiments for atomization, comprises the following steps:

[0020] The heat source is controlled to generate heat, so that the container is heated and the smoking material is heated. At the same time, the air in the gas storage clip is heated and expands and enters the container atomization tank through the hot air through the hole, thereby causing the smoking material to generate an aerosol precursor. At the same time, fresh air is controlled to enter the opening of the container atomization tank, so that the aerosol precursor is mixed with the fresh air to generate an inhalable aerosol.

[0021] Compared with the prior art, the present disclosure has at least the following advantages:

[0022] When the high-efficiency heat-not-burn atomizer device is operating, that is, when a smoker draws on the external mouthpiece, the heat source heats the air in the gas storage clamp, causing it to expand. This heat then flows through the hot air passage hole and into the atomizer tank. Furthermore, the heat source also heats the container, causing the container to heat the smokable material in the atomizer tank, thereby generating smoke in the atomizer tank.

However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0043] As shown in Figures 1 to 5, a heat-not-burn atomizer device 10 with high atomization efficiency according to one embodiment includes a heat source 100 and a container 200. The heat source 100 is provided with a mounting groove 101, and the container 200 is accommodated in the mounting groove 101. The container 200 is provided with an atomizing tank 201 for accommodating a smokable material, such as tobacco, tobacco paste, tobacco, or other existing smokable materials. The opening of the atomizing tank 201 is used to connect to an external airway, so that the smoke generated in the atomizing tank 201 mixes with the external air to reduce the temperature of the smoke and increase the amount of smoke. The area between the heat source 100 and the container 200 can form at least an air storage groove 102. The container 200 is provided with a hot air passage 202, which is respectively connected to the air storage groove 102 and the atomizing tank 201. The high-efficiency heat-not-burn atomizer device 10 also includes a fresh air restrictor 300, which is connected to the opening of the heat source body 100 and the opening of the container body 200, respectively, to close the gap between the opening of the heat source body 100 and the opening of the container body 200. In this embodiment, the opening of the atomizer tank 201 is also used to connect to an external cigarette holder.

[0044] When the heat-not-burn atomizer device 10 with high atomization efficiency is in operation, that is, when a smoker draws on the external mouthpiece, the heat source 100 heats the air in the gas storage groove 102, causing it to expand due to the heat. This heat then flows through the hot air passage hole 202 and into the atomizer tank 201. Furthermore, the heat source 100 also heats the container 200, causing the container 200 to be heated and heat the smokable material in the atomizer tank 201, thereby generating smoke in the atomizer tank 201. The smoke flows toward the opening of the atomizer tank 201 and mixes with the external air, thereby reducing the concentration of the smoke and increasing the amount of smoke. Because the air is stored in the gas storage groove 102, smoke can be generated without waiting for external air to enter, thereby improving atomization efficiency and avoiding heat waste during the process of external air entering, thereby improving heat utilization.

[0045] It should be noted that due to low parts processing accuracy, low assembly accuracy, wear and tear during use and other issues, there may be slight air intake between the opening of the closed heat source body 100 and the opening of the container 200, but it is still within the scope of protection of the present invention.

[0046] As shown in Figure 5, in one embodiment, an air storage groove 102 is formed between the bottom of the heat source 100 and the bottom of the container 200, and a hot air passage hole 202 is provided in the bottom of the container 200. In this embodiment, when the heat source 100 generates heat, the air in the air storage groove 102 expands due to the heat and immediately enters the atomization tank 201 from the bottom of the container 200. Because the air storage groove 102 is formed at the bottom of the heat source 100 and the bottom of the container 200, the outer peripheral wall of the container 200 can be connected to the inner peripheral wall of the heat source bottom, thereby enhancing the positional stability of the container 200.

[0047] In another embodiment, the gas storage groove 102 is formed between the inner peripheral wall of the heat source body 100 and the outer peripheral wall of the container body 200 , and the hot gas passing hole 202 is opened on the peripheral wall of the container body 200 .

[0048] In yet another embodiment, the gas storage clamping groove 102 includes interconnected circumferential gas storage grooves and end gas storage grooves. The area between the inner circumferential wall of the heat source body 100 and the outer circumferential wall of the container body 200 forms the circumferential gas storage groove, and the area between the bottom of the heat source body 100 and the bottom of the container body 200 forms the end gas storage grooves. In this embodiment, the gas storage clamping groove 102 surrounds the container body 200, increasing the gas capacity of the gas storage clamping groove 102 and the amount of vapor contained in the atomizer tank 201.

[0049] As shown in FIG. 5 , in one embodiment, the container 200 is located in the installation groove 101 and is sleeved with the heat source body 100 , so that the container 200 is fixed in the installation groove 101 , thereby achieving the installation of the container 200 .

[0050] As shown in FIG5 , in one embodiment, a plurality of hot air passage holes 202 are provided, spaced apart in the container 200. This allows the bottom of the container 200 to not only support the smoking material but also allow heated, expanded air to pass through. Of course, in other embodiments, the number of hot air passage holes 202 may be one.

[0051] As shown in Figure 5, in one embodiment, the heat source body 100 includes a surrounding heating portion 110 and a bottom heating portion 120. The surrounding heating portion 110 is annular in structure. The bottom heating portion 120 is connected to one end of the surrounding heating portion 110. The bottom heating portion 120 and the surrounding heating portion 110 together form a mounting groove 101. In this embodiment, when the heat-not-burn atomization device 10 is in operation, the surrounding heating portion 110 generates heat and heats the surrounding walls of the container 200, while the bottom heating portion 120 generates heat and heats the bottom of the container 200. As a result, both the surrounding walls and the bottom of the container 200 are heated, thereby improving the atomization efficiency of the smoke-generating material.

[0052] As shown in Figures 5 and 6 , in one embodiment, the high-efficiency heat-not-burn atomization device 10 further includes a heating stove 400 connected to the heat source 100. In this embodiment, when powered on, the heating stove 400 generates heat, heating the heat source 100. When powered off, the heating stove 400 ceases heat generation, allowing the heat source 100 and the container 200 to gradually return to normal temperature.

[0053] As shown in Figures 5 and 6, in one embodiment, a heating stove 400 includes a carrier 410 and a heat conductor 420. The carrier 410 defines a carrier hole 411. The heat conductor 420 is located within the carrier hole 411 and connected to the carrier 410. The heat conductor 420 is sleeved onto the heat source 100. In this embodiment, when the heat conductor 420 is powered, it generates heat and transfers the heat to the heat source 100, causing the heat source 100 to heat up. When the heat conductor 420 is powered off, it stops generating heat, allowing the heat source 100 and the container 200 to gradually return to normal temperature.

[0054] As shown in FIG1 , in one embodiment, the heat-not-burn atomizer device 10 with high atomization efficiency further includes a suction cover assembly 500. The suction cover assembly 500 defines a suction air passage 501, which communicates with an opening of the atomizer tank 201. In this embodiment, a user draws on the suction air passage 501, causing the smoke in the atomizer tank 201 to pass through the suction air passage 501 and be inhaled by the user.

[0055] As shown in FIG1 , in one embodiment, the suction cover assembly 500 is further formed with a smoke-enhancing channel 502 , which extends to the outer peripheral wall of the suction cover assembly 500 . The smoke-enhancing channel 502 is connected to the opening of the atomizer tank 201 , so that the opening of the atomizer tank 201 is connected to the external airway through the smoke-enhancing channel 502 . When the user inhales, the outside air flows through the smoke-enhancing channel 502 to the opening of the atomizer tank 201 and mixes with the smoke to reduce the temperature of the smoke and increase the amount of smoke. After the user completes a puff, the outside air also flows through the smoke-enhancing channel 502 to the atomizer tank 201 , so that the atomizer tank 201 has the gas required for atomization.

[0056] The present application also provides an atomization method, which uses the high-efficiency heat-not-burn atomization device 10 described in any of the above embodiments to perform atomization, including the steps of: controlling the heat source body 100 to generate heat, causing the container 200 to be heated and heat the smoking material, while simultaneously causing the air in the gas storage clamp 102 to expand due to the heat and enter the atomization container 201 through the hot air passage hole 202, thereby causing the smoking material to generate an aerosol precursor, and simultaneously controlling fresh air to enter the opening of the atomization container 201, so that the aerosol precursor and the fresh air are mixed to produce an inhalable aerosol. In this embodiment, the heat source body 100 is controlled to generate heat by drawing on an external cigarette holder, and the fresh air is caused to enter the opening of the atomization container 201 to mix with the aerosol precursor to form an inhalable aerosol.

[0057] In the aforementioned atomization method, when the high-efficiency heat-not-burn atomizer device 10 is operating, that is, when a smoker draws on the external mouthpiece, the heat source 100 generates heat and heats the air in the gas storage clamp 102, causing it to expand. This heat causes the hot air to pass through the hot air passage hole 202 and enter the atomizer tank 201. Furthermore, the heat source 100 also heats the container 200, causing the container 200 to be heated and heat the smokable material in the atomizer tank 201, thereby generating smoke in the atomizer tank 201. The smoke flows toward the opening of the atomizer tank 201 and mixes with the external air, thereby reducing the smoke concentration and increasing the smoke volume. Because the air is stored in the gas storage clamp 102, smoke can be generated without waiting for external air to enter, thereby improving atomization efficiency and avoiding heat waste during the external air entry process, thereby improving heat utilization.

[0058] Compared with the prior art, the present disclosure has at least the following advantages:

[0059] When the high-efficiency heat-not-burn atomizer 10 is in operation, that is, when a smoker draws on the external mouthpiece, the heat source 100 heats the air in the gas storage clamp 102, causing it to expand due to the heat. This heat then causes the hot air to pass through the hot air passage hole 202 and enter the atomizer tank 201. Furthermore, the heat source 100 also heats the container 200, causing the container 200 to be heated and heat the smokable material in the atomizer tank 201, thereby generating smoke in the atomizer tank 201. The smoke flows toward the opening of the atomizer tank 201 and mixes with the external air, thereby reducing the concentration of the smoke and increasing the amount of smoke. Since the air is stored in the gas storage clamp 102, smoke can be generated without waiting for external air to enter, thereby improving atomization efficiency, avoiding heat waste during the process of external air entering, and improving heat utilization.

[0060] As shown in FIG4 , in one embodiment, the suction cover assembly 500 includes an aerosol fresh air restrictor 510. The aerosol fresh air restrictor 510 includes a mounting portion 511 and a suction contact portion 512. The mounting portion 511 is fixedly connected to one end of the suction contact portion 512, and a transition channel 5111 is provided at the center of the mounting portion 511. As shown in FIG7 and FIG8 , further, a fresh air inflow through hole 5112 is formed at the periphery of the mounting portion 511. A fresh air smoke mixing chamber 5113 is provided on the side of the mounting portion 511 facing away from the suction contact portion 512. The fresh air smoke mixing chamber 5113 is respectively connected to the fresh air inflow through hole 5112 and the transition channel 5111. The fresh air smoke mixing chamber 5113 is also connected to the atomization tank 201.

[0061] As shown in Figure 4 , a discharge channel 5121 is further defined at the center of the suction contact portion 512. This discharge channel 5121 communicates with the transition channel 5111 and together form the smoke flow channel 5101. The suction cover assembly 500 also includes a decorative cover 520, which is attached to the surface of the aerosol fresh air restrictor 510. A smoke outlet 521 is defined at the other end of the decorative cover 520. This smoke outlet 521 communicates with the smoke flow channel 5101 and together form the suction air channel 501.

[0062] As shown in Figures 2 and 7, the decorative cover 520 is further provided with a fresh air evacuation hole 522, which is connected to the fresh air inlet hole 5112. The fresh air evacuation hole 522, the fresh air inlet hole 5112 and the fresh air smoke mixing chamber 5113 together form a smoke increasing channel 502.

[0063] As shown in Figures 4, 7, and 8, in this embodiment, the periphery of the mounting portion 511 is mounted at the opening of the atomizer tank 201, connecting the fresh air smoke mixing chamber 5113 to the opening of the atomizer tank 201. When a user draws air from the suction airway 501, smoke generated within the atomizer tank 201 flows to the opening of the atomizer tank 201. Simultaneously, outside air enters the fresh air smoke mixing chamber 5113 through the fresh air clearance hole 522 and the fresh air inflow hole 5112, allowing the outside air to mix with the smoke at the opening of the atomizer tank 201. The resulting smoke passes through the suction airway 501 and is ultimately inhaled by the user. Since the outside air, i.e., fresh air, mixes with the smoke at the opening of the atomizer tank 201, the fresh air does not need to pass through the atomizer tank 201, thereby preventing the fresh air from contacting the smokable substance within the atomizer tank 201. This, in turn, prevents the fresh air from lowering the temperature of the smokable substance, thereby improving the heating efficiency of the device.

[0064] As shown in Figure 8, in one embodiment, the fresh air and smoke mixing chamber 5113 includes a fresh air guide groove 5113a and a mixing groove 5133b. The fresh air guide groove 5113a is connected to the fresh air inlet hole 5112, and the mixing groove 5133b is respectively connected to the fresh air guide groove 5113a and the transition channel 5111. The mixing groove 5133b is also connected to the atomization groove 201.

[0065] As shown in FIG8 , in one embodiment, an angle is formed between the extension direction of the fresh air guide groove 5113a and the extension direction of the mixing groove 5133b. In this embodiment, the angle between the extension direction of the fresh air guide groove 5113a and the extension direction of the mixing groove 5133b is greater than 0° and less than 180°.

[0066] As shown in FIG8 , in one embodiment, the angle between the extension direction of the fresh air guide groove 5113a and the extension direction of the mixing groove 5133b is 90°. Of course, in other embodiments, the angle between the extension direction of the fresh air guide groove 5113a and the extension direction of the mixing groove 5133b may also be 30°, 50°, 80°, or other angles greater than 0° and less than 180°.

[0067] As shown in Figures 4 and 8 , in one embodiment, a mounting portion 511 has an embedding groove 5114 on a side facing away from the suction contact portion 512. The embedding groove 5114 is used to mount the opening of the container 200. In this embodiment, the container 200 is embedded in the embedding groove 5114, thereby improving the stability of the container 200.

[0068] As shown in FIG. 8 , in one embodiment, the embedding groove 5114 is annular, and the fresh air and smoke mixing chamber 5113 is penetrated through the embedding groove 5114 , thereby improving the installation stability of the container 200 .

[0069] As shown in Figure 8, in one embodiment, the depth of the fresh air and smoke mixing chamber 5113 is greater than the depth of the embedding groove 5114, so that the fresh air and smoke mixing chamber 5113 and the opening of the container 200 are staggered, avoiding the problem of the container 200 blocking the fresh air and smoke mixing chamber 5113.

[0070] As shown in Figure 8, in one embodiment, the number of fresh air inlet holes 5112 and the number of fresh air and smoke mixing chambers 5113 are both at least two, and at least two fresh air inlet holes 5112 are evenly arranged at the periphery of the mounting portion 511. At least two fresh air and smoke mixing chambers 5113 are connected to at least two fresh air inlet holes 5112 in a one-to-one correspondence, thereby improving the air intake efficiency of external fresh air and thereby improving the mixing efficiency of smoke and fresh air.

[0071] As shown in FIG9 , in one embodiment, an annular fixing groove 5115 is defined on the inner wall of the transition channel 5111. The heat-not-burn atomizer device 10 with high atomization efficiency also includes an aerosol filter 600. The aerosol filter 600 comprises an annular fixing peripheral portion 610 and a filter plate 620. The upper edge of the annular fixing peripheral portion 610 is embedded in the annular fixing groove 5115, securing the aerosol filter 600 within the transition channel 5111 and positioning the aerosol filter 600 in the smoke exhaust path, thereby providing a barrier to smoky substances. The annular fixing peripheral portion 610 defines a ventilation area 611, which is disposed correspondingly to and communicates with one end of the fresh air and smoke mixing chamber 5113. The periphery of the filter plate 620 is fixedly connected to the lower edge of the annular fixed peripheral portion 610 . The filter plate 620 is provided with filter mesh holes 621 . The filter mesh holes 621 are used to communicate with the atomizing tank 201 .

[0072] As shown in FIG9 , in this embodiment, when a user draws air from the air duct 501, the smoke generated in the atomizer tank 201 flows to the opening of the atomizer tank 201. At the same time, the outside air passes through the fresh air clearance hole 522 and the fresh air inflow hole 5112 in sequence and enters the fresh air smoke mixing chamber 5113, so that the outside air mixes with the smoke at the opening of the atomizer tank 201. At the same time, the smoke generated in the atomizer tank 201 passes through the filter mesh 621 and enters the transition channel 5111. At the same time, the gas in the fresh air smoke mixing chamber 5113 also enters the transition channel 5111 through the ventilation area 611, thereby increasing the amount of smoke in the transition channel 5111. The smoke in the transition channel 5111 is discharged through the exhaust channel 5121 and the smoke outlet 521 for the user to inhale the smoke. Since the smoke passes through the filter plate 620, impurities such as tobacco are blocked by the filter plate 620, which prevents the impurities in the tobacco from being discharged with the smoke, not only suppressing the waste of tobacco but also improving the taste of the smoke. In addition, since the aerosol filter 600 is arranged between the smoke outlet 521 and the atomizer tank 201, the aerosol filter 600 can block the tobacco, avoiding the problem of tobacco accidentally falling out when the electronic cigarette is moved, and suppressing the waste of tobacco.

[0073] As shown in Figure 9, in one embodiment, the ventilation area 611 is a notch. Of course, in another embodiment, the ventilation area 611 can also be a hole or a filter or other existing ventilated structures.

[0074] As shown in FIG. 9 , in one embodiment, the ventilation area 611 extends to the upper edge of the annular fixing portion 610 to increase the ventilation area 611 .

[0075] As shown in Figure 10, in one embodiment, the outer contour of the filter plate 620 includes two semicircular line segments 622 and two straight line segments 623. The two semicircular line segments 622 are opposite to each other and spaced apart, and the two straight line segments 623 are opposite to each other and spaced apart. The two ends of one semicircular line segment 622 are respectively connected to the first ends of the two straight line segments 623, and the two ends of the other semicircular line segment 622 are respectively connected to the other ends of the two straight line segments 623, so that the annular fixed peripheral portion 610 connected to the filter plate 620 has multiple surfaces, making it more convenient to take the aerosol filter element 600.

[0076] As shown in FIG. 10 , in one embodiment, the two straight line segments 623 are parallel, and the diameters of the two semicircular line segments 622 are equal, so that the filter plate 620 is flat, so that the filter plate 620 is better adapted to the flat suction nozzle.

[0077] As shown in Figure 10, in one embodiment, an annular protrusion structure 610a is provided at the upper edge of the annular fixed portion 610, and the annular protrusion structure 610a is embedded in the annular fixing groove 5115, so that the upper edge of the annular fixed portion 610 is fixed in the annular fixing groove 5115, ensuring that the aerosol filter element 600 is fixed in the transition channel 5111.

[0078] As shown in FIG. 10 , in one embodiment, the filter mesh 621 includes a plurality of through holes 6211 arranged at intervals, which improves the efficiency of smoke passing through the filter mesh 621 and reduces the obstruction of the filter plate 620 to the smoke.

[0079] As shown in FIG. 10 , in one embodiment, a plurality of through holes 6211 are arranged in an array, so that the structural strength of the filter plate 620 is relatively uniform.

[0080] As shown in Figures 11 to 14, in one embodiment, the heat-not-burn atomization device 10 with high atomization efficiency also includes an airway flow buffer 700, and the airway flow buffer 700 is provided with a connecting blocking peripheral wall 701, and the connecting blocking peripheral wall 701 is connected to the inner wall of the transition channel 5111, and the connecting blocking peripheral wall 701 is in contact with the inner wall of the transition channel 5111 to prevent smoke from passing through the gap between the airway flow buffer 700 and the inner wall of the transition channel 5111. The airway flow buffer 700 is provided with an air inlet 702 and a diverter buffer tunnel 703. The diverter buffer tunnel 703 is provided through the air inlet 702, connecting the diverter buffer tunnel 703 and the air inlet 702. There is an angle between the extension direction of the diverter buffer tunnel 703 and the extension direction of the air inlet 702. The angle between the extension direction of the diverter buffer tunnel 703 and the extension direction of the air inlet 702 is greater than 0° and less than 180°, for example, 80°, 90°, or 100°, that is, the extension direction of the diverter buffer tunnel 703 is not parallel to the extension direction of the air inlet 702. The airway flow buffer 700 is provided with a converging buffer groove 704 on the side facing away from the air inlet 702. The airway flow buffer 700 is provided with a buffer connecting groove 705 at each end. The two ends of the converging buffer groove 704 are connected to the two ends of the diverter buffer tunnel 703 through two buffer connecting grooves 705.

[0081] As shown in FIG14 , in this embodiment, when a user smokes, i.e., inhales an aerosol, smoke within transition channel 5111 enters airway flow buffer 700 through air inlet 702, and is then diverted to the two ends of diverter buffer tunnel 703, thereby splitting the aerosol into two streams. The two streams are then discharged from the two ends of diverter buffer tunnel 703. The two streams discharged from diverter buffer tunnel 703 flow to two buffer connecting grooves 705, and then merge into one stream at converging buffer groove 704. Finally, this stream is discharged through discharge channel 5121 and smoke outlet 521 in sequence for inhalation by the user. Because the smoke within transition channel 5111 is buffered by air inlet 702, diverter buffer tunnel 703, buffer connecting groove 705, and converging buffer groove 704 before being discharged, the smoke flow path and flow time are increased, thereby reducing the temperature of the discharged aerosol and improving the comfort of inhalation.

[0082] As shown in FIG. 14 , in one embodiment, the extension direction of the diversion buffer tunnel 703 is perpendicular to the extension direction of the air inlet 702 , so that the aerosol is diverted on both sides of the air inlet 702 .

[0083] As shown in FIG. 14 , in one embodiment, the air inlet hole 702 is opened at the center of the airway flow buffer 700 , so that the structural strength of the airway flow buffer 700 is more uniform.

[0084] As shown in FIG14 , in one embodiment, the air inlet 702 is connected to the center of the diversion buffer tunnel 703 . In this embodiment, the air inlet 702 diverts air from the center of the diversion buffer tunnel 703 to both ends of the diversion buffer tunnel 703 .

[0085] As shown in FIG14 , in one embodiment, the converging buffer tank 704 includes a first buffer tank 7041 and a second buffer tank 7042 that are interconnected. The first buffer tank 7041 is connected to one end of the diverting buffer tunnel 703 via a buffer connecting tank 705, and the second buffer tank 7042 is connected to the other end of the diverting buffer tunnel 703 via another buffer connecting tank 705. In this embodiment, aerosol from one buffer connecting tank 705 flows to the first buffer tank 7041, and aerosol from the other buffer connecting tank 705 flows to the second buffer tank 7042, so that the two airflows are mixed into one airflow within the converging buffer tank 704.

[0086] As shown in Figure 14, in one embodiment, there is an angle between the extension direction of the first buffer groove 7041 and the extension direction of the second buffer groove 7042, the depth of the first buffer groove 7041 gradually decreases along the smoke outlet direction, and the depth of the second buffer groove 7042 gradually decreases along the smoke outlet direction, so that the first buffer groove 7041 and the second buffer groove 7042 both have guide slopes, and the guide slopes are arranged toward the flue, which is more conducive to guiding the aerosol into the exhaust channel 5121.

[0087] As shown in FIG. 11 to FIG. 14 , in one embodiment, the inner wall of the buffer connecting groove 705 and the inner wall of the transition channel 5111 together form a buffer connecting cavity 5116 , and the aerosol in the diversion buffer tunnel 703 is discharged into the buffer connecting cavity 5116 .

[0088] As shown in Figure 11, in one embodiment, the side of the airway flow buffer 700 facing away from the air inlet 702 is connected to the inner wall of the transition channel 5111, which increases the connection area between the airway flow buffer 700 and the inner wall of the transition channel 5111 and improves the position stability of the airway flow buffer 700.

[0089] As shown in FIG14 , in one embodiment, an airway flow buffer 700 includes a smoke diverter buffer 710 and a mounting base 720. The smoke diverter buffer 710 is fixedly connected to one side of the mounting base 720. An air inlet 702 is formed in the mounting base 720. A diverter buffer tunnel 703 is formed in the smoke diverter buffer 710. A converging buffer groove 704 is formed on the side of the smoke diverter buffer 710 facing away from the mounting base 720. A buffer connecting groove 705 is formed between one end of the smoke diverter buffer 710 and one end of the mounting base 720. Another buffer connecting groove 705 is formed between the other end of the smoke diverter buffer 710 and the other end of the mounting base 720. In one embodiment, the smoke diverter buffer 710 and the mounting base 720 are integrally formed.
