The low-temperature heating smoking set provided by the invention is used for heating tobacco products to generate smoke for a user to suck.
The low-temperature heating smoking set of the invention comprises a heating head 300 for heating the cigarette 100 and an electric rod assembly 400 for providing power and controlling, wherein the heating head 300 is internally provided with a metal composite sleeve frame 310 for fixing the cigarette 100 and a heating cavity 320 for heating the cigarette.
The metal composite ferrule 310 may be installed at a central position of the bottom of the heating chamber 320 as shown in fig. 1. Of course, it may be provided at other eccentric positions as needed.
The metal composite frame 310 includes a heating ceramic sleeve 311 heated by electricity, an electromagnetic heating body 314 heated by the principle of electromagnetic induction, and a metal main support 312 for fixing the cigarette 100.
The metal main support 312 is required to mount the cigarette 100 therein, and thus it is preferably of a ring-shaped structure, and the inner diameter dimension of the metal main support 312 is matched with the outer circumferential dimension of the cigarette 100. Of course, other structures such as square or diamond may be designed.
The metal main support 312 may be made of copper, but other metal materials capable of withstanding the temperature of the heating flue gas, such as titanium or copper tungsten, are also possible. In addition, the metal main support 312 is preferably constructed in a porous structure to facilitate the flow of flue gas during heating.
In order to uniformly heat the cigarettes, an electromagnetic heating body 314 is preferably provided at the center of the metal main support 312. Of course, the object of the present invention can be achieved not in the center position, and the object is within the scope of the present invention.
The electromagnetic heating body 314 may be an electromagnetic heating knife. Of course, other forms of electromagnetic heating elements such as electromagnetic heating needles or electromagnetic heating rods are also possible.
The material of the electromagnetic heating body 314 may be iron according to the principle of electromagnetic induction. Of course, other magnetically permeable materials such as carbon steel, stainless steel, and the like are also possible.
In order to facilitate the deep cleaning of the electromagnetic heating body 314, the electromagnetic heating body 314 may be detachably connected with the metal main support 312 by a third permanent magnet 530.
It should be noted that, to implement electromagnetic induction heating, the magnetic induction coil 322 needs to be disposed around the electromagnetic heating body 314 to provide an alternating magnetic field, and the electromagnetic heating body 314 should be spaced from the magnetic induction coil 322 by a certain distance. Therefore, the magnetic induction coil 322 can be wound on the outer side of the heat insulation layer 323 of the heating cavity 320, so that the direct contact between the smoke and the magnetic induction coil 322 can be avoided, and the adhesion or corrosion of harmful substances in the smoke to the magnetic induction coil 322 is avoided. Meanwhile, the outer side temperature of the heat insulation layer 323 is lower, so that the damage of high-temperature smoke to the magnetic induction coil 322 can be further reduced, and the service life of the magnetic induction coil 322 is prolonged.
Of course, it is also possible to wind the magnetic induction coil 322 at a position inside the heat insulation layer 323, outside the inner wall 324, etc., as long as the electromagnetic heating body 314 is ensured to be in the alternating magnetic field emitted by the magnetic induction coil 322, which is the protection scope of the present invention.
In addition, a circuit and a control unit for supplying an alternating current to the magnetic induction coil 322 are provided in the electric rod assembly 400.
In order to uniformly heat the inside and outside of the cigarette 100, a heating ceramic sleeve 311 is arranged on the outer side of the metal main support 312, and the two can be detachably connected through a positioning nut 313. In addition, the fixing position of the heating ceramic sleeve 311 on the metal main support 312 can be changed by adjusting the positioning nut 313, so that the heating position of the cigarette 100 is changed. Of course, the number of the heating ceramic bushings 311 is not limited to one, and may be adjusted as needed.
The metal main support 312 is also provided externally with an annular heater 200 for heating the solid extract 234 and the tobacco particles 235. To this end, the upper portion of the metal main support 312 may be provided with a groove protruding from the outer wall thereof for placing the ring heater 200. To facilitate the operation of the ring heater 200, it is preferably provided at the upper portion of the metal main support 312.
The solid extract is prepared by adding sodium alginate into extract, and adding Ca 2+ The ion is reacted to prepare the gel, or other gel materials can be added.
In the use of the above structure, when the electromagnetic heating body 314 is used to heat the cigarette 100, firstly, the cigarette 100 is inserted into the metal composite sleeve 310, so that the electromagnetic heating body 314 is positioned inside the cigarette 100; then, by the control component in the electric rod assembly 400, for example, the magnetic induction switch 450 of the electric rod assembly 400 is turned on, so that the alternating current flows into the electromagnetic induction coil 322, and the electromagnetic induction coil 322 generates an alternating magnetic field; the electromagnetic heating body 314 located in the alternating magnetic field heats due to electromagnetic induction, and further transmits heat to the cigarette 100 in contact with the electromagnetic heating body, so that the cigarette 100 is heated from the inside.
When the heating ceramic sleeve 311 is used for heating the cigarette 100, a control circuit in the electric rod assembly 400 is started to electrify the heating ceramic sleeve 311, the heating ceramic sleeve 311 generates heat under the action of current, and the cigarette 100 is heated from the outside.
When the annular heater 200 is used for heating the solid extract 234 and the tobacco particles 235, the annular heater filled with the solid extract 234 and the tobacco particles 235 is firstly placed in the groove of the metal main support 312, and then a control circuit in the electric rod assembly 400 is started, so that the conduction between the annular heater 200 and the metal main support 312 is realized, and the heating of the solid extract 234 and the tobacco particles 235 is further realized.
It can be seen that an electromagnetic heating body 314 for heating the cigarettes 100 by using the electromagnetic induction principle is arranged inside the metal composite sleeve 310, and a ceramic heating sleeve 311 for heating the cigarettes 100 is arranged outside the metal composite sleeve 310. In addition, an annular heater 200 for heating the solid extract 234 and the tobacco particles 235 is also provided outside the metal composite frame 310. The electromagnetic heating body 314, the ceramic heating sleeve 311 and the annular heater 200 can provide different heating modes for users, so that various smoking functions such as heating the cigarettes 100, heating the solid extract 234 and the tobacco particles 235, heating the cigarettes 100, heating the solid extract 234 and compounding the tobacco particles 235 and the like are realized.
For example, during the smoking process, the cigarette 100 can be fixed in the metal main support 312, and the electromagnetic heating body 314 or the ceramic heating sleeve 311 is adopted to heat the cigarette 100 alone, or the electromagnetic heating body 314 and the ceramic heating sleeve 311 can be adopted to heat the cigarette at the same time, so that the smoking experience of the cigarette 100 is realized; or the annular heater 200 containing the solid extract 234 and the tobacco particles 235 is independently arranged, and the annular heater 200 is used for heating the solid extract 234 and the tobacco particles 235 so as to realize the suction experience of the solid extract 234 and the tobacco particles 235; of course, the cigarette 100, the solid extract 234 and the tobacco particles 235 can be filled at the same time, and the electromagnetic heating body 314, the ceramic heating sleeve 311 and the annular heater 200 are started to heat at the same time, so that the composite smoking experience of the cigarette 100, the solid extract 234 and the tobacco particles 235 is obtained. Obviously, by singly or in combination with the cigarette 100 and the ring heater 200, different smoking experiences of singly heating the cigarette 100 or the solid extract 234 and the tobacco particles 235 can be realized, and a composite smoking experience function of heating the cigarette 100 and the solid extract 234 and the tobacco particles 235 can also be realized.
In addition, the electromagnetic heating principle has the advantages of quick hot start and high heat efficiency, so that the preheating time for independently heating the cigarettes 100 by the electromagnetic heating body 314 is shorter. And the heating ceramic sleeve 311 and the electromagnetic heating body 314 heat the cigarette simultaneously, so that the inside and outside of the cigarette 100 are heated uniformly, and more uniform smoke is provided, and a better suction experience is provided for a user. It can be seen that the different heating modes of the electromagnetic heating body 314 and the ceramic heating sleeve 311 also have different pumping experiences.
In summary, the heating smoking set provided by the present invention comprises: on the one hand there are different pumping experiences provided by different heating means of the cigarettes 100 and the ring heater 200, alone or in combination; on the other hand, the device also has different suction experiences provided by different heating modes of electromagnetic heating and electric heating. Therefore, the heating smoking set provided by the invention has multiple heating modes, provides rich smoking experience functions for users, greatly meets different smoking experience requirements of the users, and solves the problem of single smoking experience caused by single heating mode of the low-temperature heating smoking set in the prior art.
On the basis of the above embodiment, in order to better achieve the heating of the solid extract 234 and the tobacco particles 235 by the ring heater 200, the structure of the ring heater 200 is defined in another embodiment.
The ring heater 200 for heating the solid extract 234 and the tobacco particles 235 includes a heating ceramic member 210, a heat conductive housing 220, and a ring heater 230.
The material of the thermally conductive housing 220 is preferably a highly thermally conductive non-porous metallic material, such as copper, copper alloy, etc., to achieve efficient thermal conduction between the metallic main support 312 and the thermally conductive housing 220.
To mate with the metal master bracket 312, the thermally conductive housing 220 is preferably of annular configuration with inner and outer peripheral dimensions that mate with the inner and outer peripheral dimensions of the recess in the metal master bracket 312.
An annular heating body 230 is disposed within the thermally conductive housing 220 and is filled with solid extract 234 and tobacco particles 235. Of course, the shape of the ring-shaped heating body 230 is preferably annular, and the inner and outer diameters of the ring should be matched with the size of the inner and outer circumferences of the heat conductive housing 220.
The heat conductive housing 220 is further provided with a heating ceramic member 210 for heating the annular heating body 230, and other heating elements such as a resistance wire may be used.
In this embodiment, the heating ceramic member 310 heats the annular heating body 230 filled with the solid extract 234 and the tobacco particles 235, and meanwhile, since the heat conducting housing 220 is connected to the metal main support 312, when the electromagnetic heating body 314 or the ceramic heating sleeve 311 heats the cigarette 100, heat is inevitably conducted to the heat conducting housing 220 through the metal main support 312, and then the annular heating body 230 is further heated. It can be seen that the smoking set heats the solid extract 234 and the tobacco particles 235 in the annular heating body 230 by the contact heat conduction between the heat conduction shell 220 and the metal main support 312 and the dual heating mode of heating the ceramic member 310, so that the uniform heating and heating rate of the solid extract 234 and the tobacco particles 235 are ensured.
On the basis of the above embodiment, in order to better achieve the storage of the solid extract 234 and the tobacco particles 235, the structure of the annular heating body 230 is defined in another embodiment.
The ring-shaped heating body 230 includes a heating aluminum case 231, a solid extract 234, tobacco particles 235, a nonwoven fabric 232, and a sealed aluminum foil 233. Wherein, the heating aluminum box 231 is used for containing solid extractum 234 and tobacco particles 235, the non-woven fabric 232 is sealed at the opening of the heating aluminum box 231, and a layer of sealing aluminum foil 233 is arranged on the non-woven fabric 232.
When not in use, the sealing aluminum foil 233 is covered on the non-woven fabric 232, so that the whole heating aluminum box 231 is effectively sealed; when the smoke filter is used, the sealing aluminum foil 233 is torn off, so that the smoke generated by heating the solid extract 234 and the tobacco particles 235 in the aluminum box 231 is pumped and flowed, and macromolecules or particles in the smoke can be filtered out by the non-woven fabric 232 at the moment, so that the pumped smoke is more comfortable.
As can be seen, heating the aluminum box 311 can achieve thermal conduction between the thermally conductive shell 220 or the heated ceramic 210 and the solid extract 234 and tobacco particles 235; the non-woven fabric 232 is mainly used for realizing the flow of the suction air and the smoke, providing a smoother suction experience, and simultaneously filtering impurities in the smoke, thereby providing a more comfortable suction experience; and the sealed aluminum foil 233 mainly prevents deterioration of the solid extract 234 or the tobacco particles 235 inside the heated aluminum case 231 when not in use, thereby avoiding adverse effects of deterioration on the suction experience.
On the basis of the above embodiment, the heating ceramic member 210 may be installed inside the heat conductive shell layer to heat the ring-shaped heating body 230.
The ceramic heating element 210 may be a ceramic heating knife or a ceramic heating pin, and is preferably disposed at the bottom of the heat conductive shell 220.
In the heating process, the heat generated by heating the ceramic member 210 is directly transferred to the inside of the annular heating body 230 and is diffused to the periphery, so that the solid extract 234 and the tobacco particles 235 in the inside of the annular heating body 230 are heated.
Because the heating ceramic element 210 is located at the bottom of the heat conducting shell, when the solid extract 234 or the tobacco particles 235 have small residual quantity, the heating ceramic element 210 at the bottom can fully heat the solid extract 234 or the tobacco particles 235, so that the waste of materials is reduced.
On the basis of the above embodiment, since the heating ceramic member 210 is heated from the inside of the ring-shaped heating body 230, the inside temperature of the ring-shaped heating body 230 is higher than the outside temperature, and in order to uniformly heat the inside and outside thereof, in another embodiment, the heat conductive shell layer 220 is made of a magnetically conductive non-porous metal material.
The thermally conductive shell 220 may be a magnetically permeable non-porous metallic material such as carbon steel, iron, or the like.
During the use of the smoking set, the electromagnetic heating switch and the electric heating switch can be simultaneously turned on, and the heat conduction shell 220 and the electromagnetic heating body 314 are both positioned in the changed magnetic field provided by the magnetic induction coil 322, so that heat can be generated due to the electromagnetic induction effect. The heat conducting shell layer 220 heats from the outside of the annular heating body 230, and the heating ceramic member 210 heats from the inside of the annular heating body 230, and the two are matched, so that the inside and the outside of the annular heating body 230 are heated uniformly.
It should be noted that electromagnetic heating has the advantages of quick start-up and high thermal efficiency, so that the adoption of the heat conductive shell layer 220 made of the magnetically permeable non-porous metal material can also reduce the preheating time of the annular heating body 230, thereby realizing efficient heating.
On the basis of the above embodiment, the heating ceramic member 210 may be installed at the outer side of the heat conductive shell 220.
The heating ceramic member 210 may be a heating ceramic tube, and is sleeved outside the heat conductive housing 220. Of course, a heating resistance wire may be wound outside the heat conductive housing 220.
In the heating process, on one hand, the heating ceramic member 210 heats the annular heating body 230 from the outer periphery of the heat conductive shell 220; on the other hand, heat is conducted from the metal main support 312 to the ring-shaped heating body 230 through the inner peripheral portion of the heat conductive shell layer 220.
It should be noted that, since the outer peripheral portion of the heat conductive shell layer 220 is far from the metal main support 312, the heat receiving from the metal main support 312 is less, and the mounting of the heating ceramic member 210 on the outer peripheral portion of the heat conductive shell layer 220 just compensates for the above-mentioned disadvantage, so that the inner and outer sides of the annular heating body 230 are heated uniformly, thereby providing a better suction experience for the user.
Based on the above embodiments, in order to increase the heat conducting effect of the heat conducting shell layer 220, in another embodiment, the heat conducting shell layer 220 is formed by a composite structure of a non-porous metal material with high heat conductivity and a gradient porous metal material.
The outer side of the heat conductive shell 220 is made of a high heat conductivity non-porous metal material, such as copper, copper alloy, etc., so as to more rapidly spread heat around the annular heat conductor 230, thereby heating the internal solid extract 234 and the tobacco particles 235.
Inside the thermally conductive shell 220 is a gradient porous metal material, such as a gradient porous copper material. Wherein, the solid extract 234 and the tobacco particles 235 penetrate into the porous structure in the heating process, so that the contact specific surface area of the solid extract 234 and the tobacco particles 235 and the heat conducting shell layer 220 is greatly increased, which is beneficial to the generation of smoke and provides better smoking experience for consumers.
Based on any of the above embodiments, in order to further enhance the heat insulation effect of the smoking set, the air duct 325 may be added to the shell of the heating chamber 320.
The shell structure of the heating chamber 320 may be provided from outside to inside with an outer shell 321, a heat insulating layer 323 and an inner wall 324, wherein the inner wall encloses a space for heating the cigarettes.
An air passage 325 through which air flows may be provided between the heat insulating layer 323 and the inner wall 324, one end of the air passage 325 is communicated with the outside air, the other end of the air passage 325 is communicated with the flue gas inside the heating cavity 320, and the air flowing direction in the air passage 325 is opposite to the generating direction of the flue gas inside the heating cavity 320. For example, the inlet of the air duct 325 may be located on the outer shell 321 through to the flue gas within the heating chamber 320.
During pumping, ambient cryogenic air enters the heating chamber 320 through the air duct 325, and further cooling of the insulation 323 and inner wall 324 is achieved during flow. In addition, because the gas has poor heat transfer effect, the air passage 325 can further block the diffusion of internal heat to the outside, and improve the heat insulation effect of the smoking set, thereby reducing the temperature of the outer wall of the smoking set.
It should be noted that, because the air flue 325 is communicated with the interior of the heating chamber 320, the external low-temperature air enters the interior of the heating chamber 320 through the air flue 325 and is mixed with the internal high-temperature flue gas, so that the temperature of the flue gas is reduced, the nozzle ironing caused by the overhigh temperature of the flue gas is avoided, and the smoothness of the suction experience is improved.
In this embodiment, a suction nozzle 330 for facilitating suction may be provided at an upper portion of the heating chamber 320. The suction nozzle 330 is actually equivalent to the extension of each part of the shell layer of the heating cavity 320, namely, the outer shell layer 321, the heat insulation layer 323, the inner wall 324 and the air channel 325 of the heating cavity are respectively connected, and finally, the heating cavity is gradually reduced to be in a suction nozzle shape, so that the user can conveniently suck the smoke.
To facilitate cleaning and maintenance of the internal components of the heating chamber 300, the suction nozzle 330 may be removably secured within the heating chamber 320. For example, the suction nozzle 330 and the main heating chamber 320 are connected by a second permanent magnet 520. Of course, other fixing methods such as clamping or threading can be adopted.
To further reduce the harmful substances in the smoke, a filter rod 600 for filtering the smoke may be placed at the end of the suction nozzle 330.
In view of the diverse needs of consumer smoking experience, a pop bead or a flavor line may be provided in the above described filter tip 600, it should be noted that the pop bead and flavor line may be provided with a variety of flavors to provide a rich choice for the consumer.
On the basis of the above embodiment, considering that the need for sucking cigarettes 100 of different specifications can be satisfied by replacing the metal composite frame 310, in another embodiment, the metal composite frame 310 is detachably connected to the heating chamber 320.
In order to replace the metal composite sleeve 310, the metal composite sleeve 310 and the heating cavity 320 may be connected by a first permanent magnet 510, for example, a permanent magnet is disposed at the bottom of the metal composite sleeve 310, and a corresponding permanent magnet is disposed on a slot 550 at the bottom of the heating cavity 320, so that the metal composite sleeve 310 may be fixed. Of course, other fixing methods, such as fastening, threading, etc., may be used.
In order to realize the suction of cigarettes 100 with different specifications, the inner diameter size of the metal main support 312 can be adjusted according to the size of the cigarettes 100, and then the metal composite sleeve 310 with different specifications is arranged to realize the insertion of cigarettes 100 with different circumferential specifications.
In addition, after the metal main support 312 is sized, the sizes of the heating ceramic sleeve 311, the electromagnetic heating body 314, and the ring heater 200 in the metal composite sleeve 310 may be adjusted accordingly, if necessary.
In this embodiment, by configuring the metal composite frames 310 with different specifications, not only the smoking of the cigarettes 100 with different specifications by the consumer can be well realized, but also the cost performance of the smoking set is further increased. In addition, the detachable connection between the metal composite rack 310 and the heating chamber 320 greatly facilitates cleaning and maintenance operations for the inside of the metal composite rack 310.
Based on the above embodiment, considering that there are more electronic components for control inside the electric rod assembly 400, in another embodiment, the heating tip 300 is detachably mounted on the electric rod assembly 400 to prevent damage to the electronic components in the electric rod assembly 400 during maintenance operation of the heating tip 300.
The electric stick assembly 400 further includes an electric stick housing for mounting the chipset 410, the chip control switching part 420, and the power supply part 430.
To reduce the long-term use cost of the smoking set, the power supply 430 is preferably a lithium battery 431 for the convenience of the user. The battery cavity 432 into which the lithium battery 431 is placed is arranged in the electric rod shell, the bottom end of the battery cavity 432 is provided with the electric rod rear cover 433 for preventing the lithium battery 431 from falling off, and the electric rod rear cover 433 can be connected with the electric rod shell in a clamping manner.
In order to achieve the best battery capacity matching required by the heating heads 300 with different powers, the lithium battery 431 can be detachably connected in the battery cavity 432, specifically, the lithium battery 431 can be fixed in a slot manner, and other fixing manners are also possible.
The chip sets 410 are connected in parallel, and during operation of the smoking article, there should be and only one chip set 410 connected to the circuit and providing the corresponding power to the heating tip 300; the chip control switching part 420 has one end connected to each chipset 410 and the other end connected to the power supply part 430, for selecting which chipset 410 is connected to the circuit; the chip control switching unit 420 is provided with chip control switching keys, which are the same as the chip sets 410 in number and in one-to-one correspondence, and can communicate the corresponding chip sets 410 with the power supply unit 430. The power supply part 430 and the chip control switching part 420 can be replaced to realize the accurate control of the power of the heating head 300, further realize the control of the heating temperature and well realize the suction of the heating cigarettes 100 with different specifications.
The electric rod assembly 400 further comprises a magnetic induction controller 440 connected in parallel with the chip, wherein one end of the magnetic induction controller 440 is connected with the power supply part 430, and the other end of the magnetic induction controller is connected with the magnetic induction coil 322, and is used for electromagnetic induction heating of the electromagnetic heating body by regulating and controlling the magnetic induction intensity.
In this embodiment, the heating head 300 can be detachably mounted on the electric rod assembly 400 through the screw threads 540, so as to avoid damage to the electronic components in the electric rod assembly 400 caused by improper operation during maintenance of the heating head 300, and further protect the sensitivity and life of the electronic components in the electric rod assembly 400. Meanwhile, as the electric rod assembly 400 is separated from the heating head 300, the damage of the power supply in the electric rod assembly 400 to the human body due to the abnormality is cut off, and the safety of the smoking set in the maintenance process is improved. Of course, other fixing methods such as clamping, magnetic attraction and the like can also be adopted.
