Description

Technical Field

[0001] The present invention relates to the field of cigarette substitute products, and in particular to a heating tube, a baking device and an electronic cigarette equipped with the same. Background Art

[0002] At present, most electronic cigarettes use tobacco-flavored liquid and atomizer components. The atomizer components heat up to atomize the liquid to form smoke, thus simulating the effect of smoking. However, the smoke formed by atomizing the liquid is still not pure enough and is not accepted by some smokers. On this basis, a method of baking cigarettes with tobacco and other baked materials has gradually appeared on the market to replace the combustion process. The baked materials produce smoke during the baking process, making the smoke taste purer.

[0003] Specifically, the baking device mainly adopts three types of baking structures: 360-degree 3D heating cylinder, central pointed piece / round rod heating element or bottom air flow heating element.

[0004] Among them, the 360-degree 3D heating tube method cannot reach the required temperature value in a short time, and because the heating tube needs to reach the preset baking temperature at the same time, it has the disadvantages of slow smoke emission speed in the early stage, strong irritation due to smoke concentration at the same time in the middle stage, and reduced irritation of smoke in the later stage.

[0005] Although the central tip / round rod heating method can reach the preset baking temperature in a short time, it is very easy to damage and break the heating element if the operation is not done properly when loading cigarettes for smoking. Therefore, it is inconvenient to use and it is not easy to clean the residue on the heating element. In addition, the central tip / round rod heating method is a local heating method, which bakes the cigarettes unevenly, thus easily causing waste of cigarettes.

[0006] The heat source of the bottom air heating body is far away from the baking position, so it cannot reach the required temperature value in a short time, and the temperature control is not accurate. The tar produced by the cigarette will accumulate on the air heating body and be heated repeatedly. Long-term use will cause the taste to change and deteriorate. Summary of the invention

[0007] Based on this, it is necessary to provide a heating tube that can heat evenly, a baking device and an electronic cigarette equipped with the same to address the problem that cigarettes cannot be heated evenly during baking.

[0038] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present invention are provided in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0039] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] like Figure 1 As shown, an electronic cigarette (not shown) of the preferred embodiment includes a main shell (not shown), a baking device 100 , an atomizing device 200 and a mounting device 300 .

[0042] The baking device 100 is installed in the main housing to be inserted into the cigarette to be baked. The cigarette is heated by the heat generated by the baking device 100 to generate baking smoke. The installation device 300 is matched with the baking device 100 to install the atomization device 200. The atomization device 200 is detachably fixed in the installation device 300 and matched with the baking device 100. The atomization device 200 is used to atomize the tobacco oil to generate atomized smoke different from baking smoke. It can be understood that the baking device 100 can be used not only to bake cigarettes, but also to bake other baking objects that can generate smoke.

[0043] The electronic cigarette integrates two working modes: baking smoke generated by baking cigarettes through the baking device 100 and atomizing smoke generated by atomizing cigarette oil through the atomizer 250. The user can choose one of the working modes according to the needs, or use the two working modes in combination. If there is residual odor in the mouth after inhaling the baking smoke generated by baking cigarettes, the atomized smoke generated by the atomizer 200 can be inhaled to remove the residual odor in the mouth.

[0044] like Figure 1-Figure 3As shown, the baking device 100 includes a heating cylinder 120 for baking cigarettes. Specifically, the heating cylinder 120 includes a heating cylinder body 122 and a heating assembly 124. A raw material receiving chamber 1221 having a bottom surface for receiving cigarettes is formed in the heating cylinder body 122, and the heating cylinder body 122 includes a first heating section connected to the bottom surface, a second heating section arranged opposite to the first heating section, and an intermediate heating section thermally connected between the first heating section and the second heating section. The first heating section, the second heating section, and the intermediate heating section are interconnected and together form the cavity wall of the raw material receiving chamber 1221. The heating assembly 124 is connected to the first heating section, and includes a first heat-conducting surface for heating the bottom surface of the raw material receiving chamber 1221 and a second heat-conducting surface for heating the first heating section. Among them, the thermal conductivity of the intermediate heating section is less than that of the first heating section.

[0045] In this way, a part of the heat generated by the heating component 124 can be quickly transferred to the bottom surface of the raw material holding chamber 1221 to quickly heat the cigarettes placed on the bottom surface, thereby shortening the smoking time; another part of the heat generated by the heating component 124 is gradually transferred to the first heating section, the middle heating section, and the second heating section, so that the first heating section, the middle heating section, and the second heating section reach the preset baking temperature in turn, so that the cigarettes can be evenly heated during the baking process, achieving a good baking effect.

[0046] Specifically in the present embodiment, a heat conduction delay groove 1226a is provided on at least one of the outer wall surface and the inner wall surface of the intermediate heating section to reduce the wall thickness of the intermediate heating section, thereby extending the heat conduction time for the intermediate heating section to reach the preset temperature, and further extending the time for the second heating section thermally connected to the intermediate heating section to reach the preset baking temperature, so that the parts of the cigarette located in the first heating section, the intermediate heating section and the second heating section are baked in turn, so that the smoke output in the entire baking process remains uniform and stable, rather than causing a sharp increase in smoke output due to a sudden rise in temperature to cause choking.

[0047] Preferably, the heat conduction delay groove 1226a is opened along the circumference of the middle heating section, thereby significantly reducing the thermal conductivity. It can be understood that the shape, size and size of the heat conduction delay groove 1226a are not limited, and the bottom wall of the heat conduction delay groove 1226a can be a plane, a curved surface, etc. to meet different requirements. In addition, the heat conduction delay groove 1226a can be a continuous groove or an intermittent groove extending along the circumference, which is not limited here. In other embodiments, the first heating section, the middle heating section and the second heating section can also be set to materials with different thermal conductivity to delay the heat transfer speed, and the thermal conductivity of the first heating section, the middle heating section and the second heating section shows a monotonically decreasing trend.

[0048] The heating assembly 124 includes a heating element 123 and a heat-conducting member 125 connected to the heating element 123 for heat conduction. A heat-conducting cavity is formed in the heat-conducting member 125. The heating element 123 is accommodated in the heat-conducting cavity and the outer surface of the heating element 123 is in contact with the inner cavity wall of the heat-conducting cavity. In this way, the heat-conducting member 125 can quickly transfer the heat generated by the heating element 123 to the outside, thereby quickly generating smoke in the initial stage.

[0049] Specifically, the heat-conducting member 125 includes a heat-conducting top plate 1252, a heat-conducting bottom plate 1253 opposite to the heat-conducting top plate 1252, and a first heat-conducting side plate 1254. The heat-conducting top plate 1252 is assembled in the first heating section and forms the bottom surface of the raw material receiving chamber 1221. The first heat-conducting surface is the surface of the heat-conducting top plate 1252 facing the raw material receiving chamber 1221. In this way, the cigarette in the raw material receiving chamber 1221 can contact the first heat-conducting surface and quickly generate smoke. The first heat-conducting side plate 1254 is connected between the outer periphery of the heat-conducting top plate 1252 and the outer periphery of the heat-conducting bottom plate 1253. The second heat-conducting surface is the surface of the first heat-conducting side plate 1254 facing the first heating section, so as to transfer part of the heat generated by the heating component 124 to the inner side wall of the first heating section, so that the heat is gradually transferred along the side wall of the heating tube body 122.

[0050] Furthermore, the heat-conducting member 125 includes a heat-conducting column 1256 and a second heat-conducting side plate 1257 extending axially, the heat-conducting top plate 1252 and the heat-conducting bottom plate 1253 are both heat-conducting rings sleeved outside the heat-conducting column 1256, the second heat-conducting side plate 1257 extends axially from the inner peripheral side of the heat-conducting top plate 1252, and the first heat-conducting side plate 1254 extends axially from the outer peripheral side of the heat-conducting bottom plate 1253. The heat-conducting column 1256 is connected along both ends of the axial direction to form a first air inlet channel 1256a connected to the raw material receiving chamber 1221, so that the tar generated by the roasted cigarette in the raw material receiving chamber 1221 can be discharged through the first air inlet channel 1256a, and the airflow delivered by the atomizing device 200 can also enter the raw material receiving chamber 1221 from the first air inlet channel 1256a. In other embodiments, the heat-conducting top plate 1252 is a sheet-like structure, and the second heat-conducting side plate 1257 can also be separately provided from the heat-conducting top plate 1252 and surround one end of the heat-conducting column 1256 .

[0051] In one embodiment, the heating cylinder 120 further includes a filter sheet 126 having at least one filter hole, the filter sheet 126 covers the surface of the heat-conducting top plate 1252 facing the raw material receiving chamber 1221, and the filter hole is connected to the first air inlet channel 1256a and the raw material receiving chamber 1221. In this way, the filter hole can prevent impurities such as tobacco in the cigarette from entering the atomization device 200 through the first air inlet channel 1256a.

[0052] In one embodiment, the baking device 100 includes an upper insulation seat 140, a lower insulation seat 160, and a connecting tube 180. The connecting tube 180 is sleeved between the upper insulation seat 140 and the lower insulation seat 160, and together with the upper insulation seat 140 and the lower insulation seat 160, forms a space for accommodating the heating tube 120, and the upper insulation seat 140 and the lower insulation seat 160 are respectively sleeved on the outer periphery of the two axial ends of the heating tube 120. In this way. The heating tube 120 is accommodated in the space formed by the upper insulation seat 140, the lower insulation seat 160 and the connecting tube 180 and is fixed by the upper insulation seat 140 and the lower insulation seat 160.

[0053] Specifically, the upper heat-insulating seat 140 is generally in a hollow cylindrical structure, and a through hole is formed through the upper heat-insulating seat 140 to connect with the raw material containing cavity 1221 for inserting cigarettes. The lower heat-insulating seat 160 includes a heat-insulating seat body in a "T" shape and a heat-insulating seat connecting part surrounding the outer wall of the large end of the heat-insulating seat body. The connecting pipe 180 is sleeved on the outer wall of the heat-insulating seat connecting part to connect the lower heat-insulating seat 160. The heat-insulating seat body is formed with a second air inlet channel 162, and one end of the heat-conducting column 1256 of the heat-conducting member 125 away from the heat-conducting bottom plate 1253 is inserted into the second air inlet channel 162, so that the two ends of the second air inlet channel 162 are respectively connected with the first air inlet channel 1256a and the atomizing device 200 to allow tar and air flow to flow through.

[0054] Furthermore, the heating element 123 is electrically connected with a heating element pin, and the heating element pin sequentially passes through the heat-conducting bottom plate 1253 of the heat-conducting member 125 and the lower heat-insulating seat 160 to be electrically connected to the external structure to obtain current.

[0055] In the above-mentioned baking device 100, the heat generated by the heating element 123 is first transferred to the heat-conducting top plate 1252 and the heat-conducting bottom plate 1253 in contact therewith, and the heat-conducting top plate 1252 transfers the heat to the filter 126 through the first heat-conducting surface, and then transfers the heat to the cigarette to bake the cigarette. Since the transfer distance of heat from the heating element 123 to the heat-conducting top plate 1252 is very short, the transfer time is very short and the heat loss is very small, and the filter 126 can quickly reach the preset baking temperature to bake the cigarette or other baking objects and generate baking smoke.

[0056] As the heating element 123 continues to generate heat, the heat is gradually transferred from the heat-conducting bottom plate 1253 to the first heating section of the heating tube body 122 through the first heat-conducting side plate 1254, and then transferred to the middle heating section along the side wall. When the heat is transferred to the middle heating section, the thickness of the middle heating section is reduced, so the speed of heat transfer will be further slowed down, resulting in the middle heating section taking a certain amount of time to reach the preset baking temperature, and thus making the second heating section take longer to reach the preset baking temperature. In this way, the filter 126, the middle heating section and the second heating section reach the preset baking temperature in turn to achieve gradual vertical heating of the temperature, so that the smoke emission has a faster starting speed, and the amount of baking smoke generated is uniform and has a higher consistency.

[0057] In addition, since the heat-conducting member 125 is provided with a first air inlet channel 1256a connected to the raw material receiving chamber 1221, and the lower heat-insulating seat 160 is provided with a second air inlet channel 162 connected to the first air inlet channel 1256a, the airflow in the atomizing device 200 can pass through the second air inlet channel 162 and the first air inlet channel 1256a to enter the raw material receiving chamber 1221, and at the same time, the tar produced by baking in the raw material receiving chamber 1221 can be discharged from the baking device 100 along the first air inlet channel 1256a and the second air inlet channel 162. In another embodiment, a gap can be provided between the cigarette and the heating cylinder body 122 so that the airflow flows from between the cigarette and the inner wall of the heating cylinder body 122 to the end of the cigarette contacting the filter sheet 126.

[0058] like Figure 1 , Figure 6-Figure 8 As shown, the atomizer 200 is detachably connected to one end of the baking device 100 and includes a tar recovery pipe 210 and an atomizer 250. The tar recovery pipe 210 is formed with a tar recovery chamber 212 that is connected to the raw material receiving chamber 1221 in the baking device 100 through the second air inlet channel 162 and the first air inlet channel 1256a. In this way, the tar generated by baking the cigarette in the raw material receiving chamber 1221 can enter the tar recovery chamber 212 along the first air inlet channel 1256a and the second air inlet channel 162. After the atomizer 250 is removed, the tar in the tar recovery chamber 212 can be easily cleaned, thereby preventing the tar from accumulating in the electronic cigarette and affecting the taste of the smoke and the smoothness of ventilation.

[0059] The atomizer 250 is connected to one end of the tar recovery pipe 210 away from the baking device 100, and specifically includes a guide pipe 252 connected to the tar recovery pipe 210 and an atomizing assembly 254 disposed in the guide pipe 252. The atomizing assembly 254 is formed with an air flow channel and an atomizing chamber 2544a connecting the air flow channel and the tar recovery chamber 212. In this way, the air flow in the atomizing chamber 2544a can be discharged through the air flow channel, the tar recovery chamber 212, the second air inlet channel 162, the first air inlet channel 1256a and the raw material containing chamber 1221. In this embodiment, the tar recovery pipe 210 and the guide pipe 252 are integrally formed.

[0060] The atomizing device 200 also includes an oil blocking member 230 disposed between the tar recovery chamber 212 and the atomizing assembly 254. The oil blocking member 230 is provided with a smoke outlet 232 connecting the tar recovery chamber 212 and the atomizing chamber 2544a, thereby allowing air flow to pass through while preventing the tar in the tar recovery chamber 212 from flowing along the side wall of the tar recovery chamber 212 toward the atomizing assembly 254.

[0061] Furthermore, the atomizing device 200 includes a gland assembly 270, which is sealed and detachably disposed between the tar recovery pipe 210 and the baking device 100, and a gland through hole connected to the tar recovery chamber 212 is formed through the gland assembly 270. In this way, the end of the lower insulation seat 160 of the baking device 100 away from the upper insulation seat 140 can be inserted into the gland through hole, and the gap between the tar recovery pipe 210 and the lower insulation seat 160 is closed by the gland assembly 270 to prevent airflow leakage.

[0062] Specifically, the gland assembly 270 includes a gland seat 272 and a seal 274. The tar recovery pipe 210 is sleeved on the outer periphery of the gland seat 272. The seal 274 is sealed and embedded in the inner periphery of the gland seat 272 and is provided with a gland through hole. In this embodiment, the seal 274 is elastic and is in a compressed state when it is embedded in the gland seat 272, thereby achieving a good sealing effect to prevent gas from leaking from between the tar recovery pipe 210 and the lower insulation seat 160.

[0063] The atomizing assembly 254 includes a positive electrode ejector pin 2541, an atomizing base 2542, a vent pipe 2544, and a heating assembly 2546. The positive electrode ejector pin 2541 is inserted into the atomizing base 2542, and the atomizing base 2542 is connected to one end of the atomizing tube 252 away from the tar recovery pipe 210. A sealing ring 2542a is also sleeved on the atomizing base 2542 to prevent gas leakage. The vent pipe 2544 is supported on the atomizing base 2542 and has an axially longitudinally extending atomizing chamber 2544a formed therein, which is connected to the tar recovery chamber 212 to allow airflow to pass through. An oil storage chamber is defined between the ventilation pipe 2544 and the guide tube 252 to store the tobacco oil, and an oil inlet 2544b connecting the oil storage chamber and the atomization chamber 2544a is opened on the ventilation pipe 2544. The heating component 2546 is arranged in the atomization chamber 2544a. The positive and negative electrodes of the heating component 2546 are electrically connected to the positive electrode ejector pin 2541 and the atomization base 2542 respectively to atomize the tobacco oil adsorbed in the oil storage chamber. The heat generated by the heating component 2546 can atomize the tobacco oil to generate atomized smoke.

[0064] Furthermore, the oil storage cavity is filled with an oil storage member 2548, which is exposed in the atomizing cavity 2544a through the oil inlet 2544b and contacts the heating component 2546 to provide the heating component 2546 with smoke oil. In this embodiment, the oil storage member 2548 is oil storage cotton adsorbed with smoke oil, and the vent pipe 2544 includes a first end 2544c supported on the atomizing base 2542 and a second end 2544d away from the atomizing base 2542. The outer diameter of the first end 2544c of the vent pipe 2544 is greater than the outer diameter of the second end 2544d, and the oil inlet 2544b is opened through the first end, so that the heating component 2546 contacts the oil storage cotton and facilitates the heating component 2546 to absorb smoke oil. In other embodiments, the oil storage member 2548 can also be formed of other materials. In other embodiments, liquid smoke oil is stored in the oil storage cavity.

[0065] Specifically, the heating component 2546 includes a heating wire 2546a and an oil-conducting cotton 2546b. The heating wire 2546a is wound around the cylindrical oil-conducting cotton 2546b. The oil-conducting cotton 2546b is always in contact with the oil storage member 2548 to continuously absorb the smoke oil. In this way, the heating wire 2546a is energized to generate heat to atomize the smoke oil in the oil-conducting cotton 2546b to form atomized smoke.

[0066] Furthermore, an oil blocking member 230 is stacked on one end of the oil storage member 2548 away from the heating component 2546, and the oil blocking member 230 is used to prevent the tobacco oil in the oil storage member 2548 from flowing back into the tar recovery chamber 212. Furthermore, the surface of the oil blocking member 230 facing the tar recovery chamber 212 is formed with an oil guiding surface inclined toward the direction close to the oil storage member 2548, so as to guide the tar to flow into the oil storage member 230 and avoid the accumulation of tar in the atomization chamber 2544a to affect the atomization effect.

[0067] like Figure 1 , Figure 4 and Figure 5 As shown, the electronic cigarette further includes a mounting device 300 for fixing the atomizing device 200 , and the atomizing device 200 is stably mounted in the main housing through the mounting device 300 and matched with the baking device 100 .

[0068] The mounting device 300 is accommodated in the main housing, and includes a mounting tube 310 and a mounting structure 320 mounted on one end of the mounting tube 310. The other end of the mounting tube 310 is inserted into the lower heat insulation seat 160 of the baking device 100. The atomizer 250 can be inserted into the mounting tube 310 from one end of the mounting tube 310 connected with the mounting structure 320 to be matched with the baking device 100. The atomizer device 200 includes a clamping structure 290 detachably matched to one end of the atomizer 250. When the atomizer 250 is inserted into the mounting tube 310, the clamping structure 290 and the mounting structure 320 are detachably clamped to fix the atomizer 250. The holding structure 290 includes a holding space with variable size in the disassembly and assembly direction of the atomizer 250, and the installation structure 320 includes a movable part 325 that can move in the disassembly and assembly direction perpendicular to the atomizer 250. When the movable part 325 is confined in the holding space, the holding structure 290 is connected to the installation structure 320.

[0069] In this way, the atomizing device 200 can be installed in the mounting device 300 through the clamping structure 290, and the mounting structure 320 is connected to the clamping structure 290 through the movable part 325, so that the installation of the atomizing device 200 is quick and simple, thereby facilitating the replacement of the atomizing device 200 and conveniently cleaning the tar recovery chamber 212 of the atomizing device 200.

[0070] Specifically, the mounting structure 320 includes a three-way bracket 321 which is sleeved on one end of the mounting tube 310, and the three-way bracket 321 includes a first bracket through hole 3214, a second bracket through hole 3216 and a third bracket through hole 3218. The first bracket through hole 3214 passes through the three-way bracket 321, and the three-way bracket 321 is sleeved on the outer periphery of the mounting tube 310 away from the baking device 100 through the first bracket through hole 3214. The first bracket through hole 3214 passes through the three-way bracket 321, and the second bracket through hole 3216 and the third bracket through hole 3218 are symmetrically formed on the side wall of the first bracket through hole 3214. Two movable parts 325 are respectively installed in the second bracket through hole 3216 and the third bracket through hole 3218, and can be respectively extended and retracted along the central axis of the second bracket through hole 3216 and the third bracket through hole 3218 to clamp or detach from the clamping structure 290.

[0071] Furthermore, the mounting structure 320 further includes a positive electrode pressure cap 322, an airway pressure cap 323 and two first elastic members 324. The positive electrode pressure cap 322 is sleeved on the end of the second bracket through hole 3216 away from the third bracket through hole 3218, one end of one of the first elastic members 324 abuts against the positive electrode pressure cap 322, and the other end abuts against the movable member 325 and applies a thrust toward the clamping space to the movable member 325. The airway pressure cap 323 is sleeved on the end of the third bracket through hole 3218 away from the second bracket through hole 3216, and one end of the other first elastic member 324 abuts against the airway pressure cap 323, and the other end abuts against the movable member 325 and applies a thrust toward the clamping space to the movable member 325. In this way, the two movable members 325 always have a tendency to move toward each other under the action of the first elastic members 324 to clamp the clamping structure 290.

[0072] Further, the diameter of the second bracket through hole 3216 at one end close to the first bracket through hole 3214 is smaller than the diameter of the end away from the first bracket through hole 3214, so an annular second bracket abutting surface is formed in the second bracket through hole 3216. The movable member 325 includes a movable member body 3252 and a movable member abutting portion 3254, the movable member abutting portion 3254 is connected to the end of the movable member 325 away from the first bracket through hole 3214, and the outer diameter of the movable member abutting portion 3254 is greater than the outer diameter of the movable member body 3252. Therefore, the second bracket abutting surface can abut the end surface between the movable member abutting portion 3254 and the movable member body 3252, thereby limiting the moving range of the movable member 325 perpendicular to the disassembly and assembly direction of the atomization device 200, and preventing the movable member 325 from being separated from the second bracket through hole 3216 under the action of the first elastic member 324. It can be understood that the shape of the third bracket through hole 3218 is symmetrical to the shape of the second bracket through hole 3216 along the central symmetry axis of the first bracket through hole 3218 , so that the two movable members 325 can jointly hold the atomizer 250 .

[0073] In one embodiment, the outer side wall of the movable member 325 close to the atomizer 250 is provided with a movable member inclined surface 3252a, and the distance of the movable member inclined surface 3252a relative to the central axis of the atomizer 250 gradually increases from the end close to the atomizer 250 to the end away from the atomizer 250. In this way, when the clamping structure 290 contacts the movable member inclined surface 3252a and moves along the central axis direction of the atomizer 250, as the movable member inclined surface 3252a cooperates with the clamping structure 290 at different positions in the central axis direction, the movable member 325 can move in a direction perpendicular to the central axis direction of the atomizer 250, thereby converting the movement of the clamping structure 290 along the central axis direction of the atomizer 250 into the movement of the movable member 325 along the axis direction of the second bracket through hole 3216 or the third bracket through hole 3218. It can be understood that the movable member inclined surface 3252a may not be provided on the movable member 325, but the clamping inclined surface may be provided on the clamping structure 290.

[0074] The mounting structure 320 also includes a negative electrode 326 and a negative electrode pushing assembly. The negative electrode 326 is sleeved on the mounting tube 310 and accommodated in the first bracket through hole 3214 of the three-way bracket 321. The negative electrode pushing assembly is sleeved on the mounting tube 310 and abuts against one end of the negative electrode 326. The end of the negative electrode 326 away from the negative electrode pushing assembly abuts against the clamping structure 290. The negative electrode pushing assembly is used to apply a thrust to the negative electrode 326 in the direction of disassembly of the atomizer 250.

[0075] Specifically, the negative electrode pushing assembly includes a fixing ring 3272, a connecting tube 3274 and a second elastic member 3276. The fixing ring 3272 is fixedly sleeved on the mounting tube 310, the connecting tube 3274 is sleeved on the mounting tube 310, and the two ends of the connecting tube 3274 are respectively fixedly sleeved on the fixing ring 3272 and the outer wall of the three-way bracket 321 to fix the three-way bracket 321 relative to the mounting tube 310. The second elastic member 3276 is sleeved on the mounting tube 310 and is located between the fixing ring 3272 and the negative electrode 326. One end of the second elastic member 3276 abuts against the fixing ring 3272, and the other end extends into the first bracket through hole 3214 and abuts against the negative electrode 326. In this way, the second elastic member 3276 can apply a thrust in the direction of disassembly of the atomizer 250 to the atomizer 250 through the negative electrode 326, so that the atomizer 250 is firmly clamped in the mounting device 300.

[0076] Furthermore, the side wall of the negative electrode 326 near one end of the fixing ring 3272 bends and extends outward, and the inner wall of the first bracket through hole 3214 is also protruding with a support portion to support the negative electrode 326, thereby limiting the range of movement of the negative electrode 326 so that the negative electrode 326 is always in contact with the second elastic member 3276.

[0077] The installation device 300 further includes a first conductive wire 330 and a second conductive wire 340. One end of the first conductive wire 330 is electrically connected to the external structure, and the other end is installed on the fixing ring 3272 and electrically connected to the fixing ring 3272. The current of the first conductive wire 330 is sequentially transmitted to the negative electrode 326 through the fixing ring 3272 and the second elastic member 3276. One end of the second conductive wire 340 is electrically connected to the external structure, and the other end is installed on the positive electrode pressure cap 322 and electrically connected to the positive electrode pressure cap 322. The current of the second conductive wire 340 can be sequentially transmitted to the movable member 325 through the positive electrode pressure cap 322 and the first elastic member 324.

[0078] In one embodiment, the installation device 300 further includes an air switch 350 provided with a signal conductive line 352, an air switch accommodating chamber is provided at one end of the airway gland 323 away from the positive electrode gland 322, the air switch 350 is embedded in the air switch accommodating chamber, and the signal conductive line 352 extends out of the air switch accommodating chamber to connect to an external control structure such as an electronic solution board. In this way, when the user inhales the electronic cigarette, the negative air pressure generated inside the main shell activates the air switch 350, and the air switch 350 feeds back a signal to the external control structure connected to it through the signal conductive line 352, and the external control structure starts to provide current to the first conductive line 330 and the second conductive line 340 so that the atomization assembly 254 starts to work to atomize the tobacco oil, or provides electrical energy to the heating element 123 so that the heating element 123 generates heat to bake the cigarette.

[0079] like Figure 1 , Figure 6 and Figure 8 As shown, the clamping structure 290 is provided with a first clamping inclined surface and a second clamping inclined surface located on both sides of the clamping space in the disassembly and assembly direction of the atomizer 250, and the distances of the first clamping inclined surface and the second clamping inclined surface relative to the central axis of the atomizer 250 are gradually increased from the end close to the atomizer 250 to the end away from the atomizer 250. In this way, when the clamping assembly 292 and the movable member 325 slide relative to each other, the first clamping inclined surface or the second clamping inclined surface can push the movable member 325 to move in the direction away from the central axis of the atomizer 250 to make room for the movement of the clamping structure 290.

[0080] The clamping structure 290 includes a clamping base 291 and a clamping assembly 292. One end of the clamping base 291 can be detachably connected to the atomizer 250 to connect the clamping structure 290 with the atomizer 250. The clamping assembly 292 is sleeved on one end of the clamping base 291 away from the atomizer 250 to form a clamping space to limit the movable part 325.

[0081] Specifically, the clamping assembly 292 includes a clamping ring 2922, a bottom ring 2924 and a movable ring 2926. The clamping ring 2922 is sleeved on the outer periphery of the end of the clamping base 291 away from the atomizer 250, and the bottom ring 2924 is sleeved on the outer periphery of the end of the clamping ring 2922 away from the clamping base 291 to form an activity space together with the clamping ring 2922. The movable ring 2926 is sleeved on the clamping ring 2922 and is located in the activity space. The movable ring 2926 and the clamping ring 2922 are clearance-matched so that they can slide relative to the clamping ring 2922 along the central axis direction of the atomizer 250 to form a clamping space of variable size.

[0082] More specifically, the clamping ring 2922 includes a first section, a second section, and a third section which are connected in sequence and have decreasing outer diameters in sequence. The bottom ring 2924 is sleeved on the third section, and the movable ring 2926 is sleeved on the second section. The side wall of the first section away from one end of the second section includes a clamping ring inclined surface 2922a as a first clamping inclined surface, and the side wall of the movable ring 2926 away from one end of the bottom ring 2924 includes a movable ring inclined surface 2926a as a second clamping inclined surface. The movable member inclined surface 3252a of the movable member 325 can cooperate with the clamping ring inclined surface 2922a or the movable ring inclined surface 2926a to move relative to each other, so as to convert the movement of the clamping structure 290 in the disassembly direction of the atomizing device 200 into the movement of the movable member 325 in a direction perpendicular to the disassembly direction of the atomizing device 200. It can be understood that the retaining ring 2922 and the movable part 325 may not be provided with the retaining ring inclined surface 2922a and the movable ring inclined surface 2926a, but may directly cooperate with the movable part inclined surface 3252a of the movable part 325 through the edge.

[0083] like Figure 1 and Fig. 9 As shown, when the atomizer 200 is inserted into the mounting device 300, the movable ring inclined surface 2926a of the clamping ring 2922 contacts the movable member inclined surface 3252a of the movable member 325 and slides relative to the movable member inclined surface 3252a, thereby converting the linear motion along the insertion direction of the atomizer 250 into a radial motion perpendicular to the linear motion, pushing the movable member 325 to move in a direction away from the central axis of the atomizer 250 and basically shrinking in the second bracket through hole 3216 to avoid blocking the movement of the atomizer 200. When the atomizer 200 moves relative to the mounting device 300 to the clamping space corresponding to the movable member 325, the side wall of the clamping ring 2922 leaves the movable member 325, the thrust on the movable member 325 away from the central axis of the atomizer 250 disappears, and the movable member 325 extends into the clamping space under the support of the second elastic member 3276, so that the atomizer 200 is fixed in the mounting device 300.

[0084] Furthermore, since the end of the negative electrode 326 away from the fixed ring 3272 abuts against the clamping base 291, the second elastic member 3276 applies a thrust extending in the disassembly direction of the atomizer 250 to the clamping ring 2922 through the negative electrode 326 and the clamping base 291. When the movable member 325 is clamped in the clamping space, the end surface between the first section and the second section of the clamping ring 2922 abuts against the side wall of the movable member 325, thereby preventing the atomizer 250 from coming off the mounting device 300.

[0085] In one embodiment, the holding structure 290 further includes an elastic electrode 294 and a third conductive wire 295. The elastic electrode 294 is held in the holding base 291 and one end of the elastic electrode 294 is inserted into the positive electrode ejector 2541 to be electrically connected to the positive electrode ejector 2541. One end of the elastic electrode 294 away from the positive electrode ejector 2541 is electrically connected to the third conductive wire 295. When the atomization device 200 is mounted on the mounting device 300, one end of the third conductive wire 295 away from the elastic electrode 294 is electrically connected to the holding ring 2922 of the mounting device 300, so that the current on the holding ring 2922 is successively transmitted to the positive electrode ejector 2541 through the third conductive wire 295 and the elastic electrode 294. The positive electrode ejector 2541 is electrically connected to the heating wire 2546a to provide a positive current to the heating wire 2546a.

[0086] Furthermore, if Figure 6 As shown, the atomizer 250 further includes a first insulating ring 2543, a second insulating ring 297 and a third insulating ring 298. The first insulating ring 2543 is sleeved on the positive electrode ejector 2541 to be located between the outer side wall of the positive electrode ejector 2541 and the inner side wall of the atomizing base 2542, so that the positive electrode ejector 2541 and the atomizing base 2542 are insulated from each other. In this way, the positive electrode pin of the heating wire 2546a is fixed between the positive electrode ejector 2541 and the first insulating ring 2543 to be electrically connected to the positive electrode ejector 2541, and the negative electrode pin of the heating wire 2546a is fixed between the atomizing base 2542 and the first insulating ring 2543 to be electrically connected to the atomizing base 2542. The second insulating ring 297 is sleeved between the clamping ring 2922 and the clamping base 291 to insulate the clamping ring 2922 and the clamping base 291. The third insulating ring 298 is sleeved outside the elastic electrode 294 and clamped in the clamping base 291, so as to insulate the elastic electrode 294 from the clamping base 291 and avoid mutual interference between the positive and negative currents.

[0087] like Figure 1 and Fig. 9 As shown, the installation process of the atomizing device 200 is as follows:

[0088] Insert the atomizer 250 into the mounting tube 310, apply a thrust toward the baking device 100 to the bottom ring 2924, and the holding ring inclined surface 2922a of the holding ring 2922 contacts the movable member inclined surface 3252a of the movable member 325 and slides relative to the movable member inclined surface 3252a, thereby converting the linear motion along the insertion direction of the atomizer 250 into a radial motion perpendicular to the linear motion, pushing the movable member 325 to move in a direction away from the first bracket through hole 3214. When the atomizer 200 moves relative to the mounting device 300 until the holding space corresponds to the movable member 325, the holding ring 2922 leaves the movable member 325, and the movable member 325, which loses the support of the holding structure 290, extends into the holding space under the push of the second elastic member 3276, thereby fixing the atomizer 200 in the mounting device 300.

[0089] like Fig.10 and Fig.11 As shown, the disassembly process of the atomizing device 200 is as follows:

[0090] A thrust is applied to the bottom ring 2924 toward the baking device 100. At this time, the movable ring inclined surface 2926a on the movable ring 2926 contacts the movable member inclined surface 3252a of the movable member 325. As the bottom ring 2924 moves, the movable ring 2926 pushes the movable member 325 to move away from the first bracket through hole 3214 and compresses the first elastic member 324 until the side wall of the movable ring 2926 abuts against the side wall of the movable member 325 and the first elastic member 324 cannot be further compressed. Then, the pressure applied to the bottom ring 2924 is released. At this time, the clamping base 291 moves away from the baking device 100 under the push of the second elastic member 3276, thereby driving the movable member 325 to move. At the same time, the movable ring 2926 is clamped by the two movable members 325 under the action of the first elastic member 324 and remains stationary relative to the installation device 300. Therefore, the clamping space gradually decreases until the movable member 325 contacts the end face of the movable ring 2926 close to the atomizer 250. At this time, the side wall of the movable member 325 abuts against the side wall of the movable ring 2926, and the clamping ring 2922 continues to move outward under the push of the second elastic member 3276. At the same time, since the side wall of the clamping ring 2922 always abuts against the side wall of the movable member 325, the first elastic member 324 is always in a compressed state until the clamping ring 2922 leaves the movable member 325. At this time, the atomization device 200 can be completely separated from the installation device 300.

[0091] Furthermore, the process of atomizing the e-cigarette oil by the electronic cigarette is as follows:

[0092] like Figure 1As shown, when the user inhales the electronic cigarette, the negative air pressure generated inside the main shell activates the air switch 350, and the air switch 350 feeds back a signal to the external control structure connected to it through the signal conductive line 352, and the external control structure starts to provide current to the first conductive line 330 and the second conductive line 340.

[0093] Afterwards, the current of the first conductive wire 330 is successively transmitted through the mutually contacting fixed ring 3272, the first elastic member 324, the negative electrode 326, the clamping base 291, and the atomizing base 2542, and finally transmitted to the negative electrode of the heating wire 2546a. At the same time, the current of the second conductive wire 340 is successively transmitted through the mutually contacting positive electrode pressure cap 322, the second elastic member 3276, the movable member 325, the clamping ring 2922, the third conductive wire 295, the elastic electrode 294, and the positive electrode ejector pin 2541, and finally transmitted to the positive electrode of the heating wire 2546a. In this way, the heating wire 2546a generates heat to atomize the tobacco oil in the oil storage member 2548 to form smoke.

[0094] Furthermore, the airway gland 323, the movable part 325, the movable ring 2926, the retaining ring 2922, the elastic electrode 294 and the positive electrode ejector pin 2541 are all penetrated with through holes allowing airflow to pass through to form an airflow channel. When the atomizer 200 is working, the airflow transmission direction of the electronic cigarette is as follows:

[0095] After entering from the air switch 350, the air passes through the airway pressure cover 323, the movable part 325, the movable ring 2926, the retaining ring 2922, the elastic electrode 294, and the positive electrode ejector pin 2541 in sequence to enter the atomization chamber 2544a formed by the guide tube 252 to participate in the atomization of the tobacco oil. The smoke generated by the atomization passes along the ventilation pipe 2544 in sequence through the tar recovery chamber 212 formed by the tar recovery pipe 210, the second air inlet channel 162 opened by the lower insulation seat 160 of the baking device 100, and the first air inlet channel 1256a opened on the heat conductive member 125, and is finally discharged from the raw material containing chamber 1221 formed by the heating tube body 122.

[0096] When the baking device 100 is working, the airflow transmission direction of the electronic cigarette is as follows:

[0097] After the air flow enters from the air switch 350, it passes through the airway pressure cover 323, the movable part 325, the movable ring 2926, the clamping ring 2922, the elastic electrode 294, and the positive electrode ejector pin 2541 in sequence to enter the atomization chamber 2544a, and then passes along the ventilation pipe 2544 in sequence through the tar recovery chamber 212 formed by the tar recovery pipe 210, the second air intake channel 162 opened by the lower insulation seat 160 of the baking device 100, and the first air intake channel 1256a opened on the heat conductive part 125 to reach the raw material containing chamber 1221 formed by the heating tube body 122 to participate in the baking of the cigarette, and finally forms smoke and is discharged from the raw material containing chamber 1221.

[0098] The above-mentioned electronic cigarette, through the setting of the tar recovery chamber 212, solves the problem that the tar residue generated by the baking device 100 baking cigarettes is piled up in the electronic cigarette, causing the smoke taste to deteriorate and the ventilation to be insufficient. Moreover, the user can choose to use the baking device 100 to bake the cigarettes or the atomizing device 200 to atomize the cigarette oil according to the needs, so as to meet different needs and remove the odor left in the mouth by smoking cigarettes. In addition, since the atomizer 250 can be quickly disassembled and assembled, it is convenient for replacing the atomizer 250 and cleaning the tar, thereby extending the service life of the electronic cigarette.

[0099] A control method of an electronic cigarette in this preferred embodiment includes the following steps:

[0100] S110 : receiving a first control signal and starting a baking operation mode to control the baking device 100 to bake the object to be baked in the raw material receiving cavity 1221 .

[0101] Specifically, the electronic cigarette includes a control device, which can receive a first control signal to energize the heating element 123, and the heat generated by the heating element 123 can bake the cigarette to form smoke. Specifically, in the baking working mode, the external airflow enters the raw material containing chamber 1221 through the airflow channel, the atomizing chamber 2544a, and the tar recovery chamber 212 in sequence.

[0102] S120: receiving a second control signal different from the first control signal and starting an atomization working mode to control the atomization device 200 to atomize the e-liquid in the atomization chamber 2544a.

[0103] Specifically, the control device can receive the second control signal to energize the first conductive wire 330, the second conductive wire 340 and the third conductive wire 295, so that the heating component 2546 in the atomizer 250 is heated to atomize the e-liquid. Specifically, in the atomization working mode, the external airflow enters the atomization chamber 2544a through the airflow channel to form smoke, and the smoke flows out through the tar recovery chamber 212 and the raw material containing chamber 1221.

[0104] Furthermore, the control method of the electronic cigarette also includes: when the baking working mode or the atomization working mode is started, the air switch 350 is started and the number of puffs of the electronic cigarette is recorded.

[0105] In this way, the number of times and time of smoking of the user are monitored to control the smoking time, and the user can also be reminded to replace the atomizing device 200.

[0106] The above-mentioned electronic cigarette control method can selectively use the baking device 100 to bake the cigarette and the atomizing device 200 to atomize the tobacco oil in two working modes, so it can meet different needs of users. After inhaling the smoke formed by baking, the smoke formed by the tobacco oil can continue to be inhaled to remove the bad smell in the mouth.

[0107] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0108] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
