The low-temperature heating smoking appliance provided by the invention is used for heating tobacco products to generate smoke for users to smoke.

The low-temperature heating smoking appliance of the present invention includes 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 provided with a metal composite sleeve 310 for fixing the cigarette 100 and The heating cavity 320 for heating cigarettes.

The metal composite sheath 310 may be installed at the center of the bottom of the heating chamber 320, as shown in FIG. 1 . Of course, it can also be set at other eccentric positions as required.

The metal composite sleeve 310 includes a heating ceramic sleeve 311 through electric heating, an electromagnetic heating body 314 generating heat through electromagnetic induction, and a metal main bracket 312 for fixing the cigarette 100 .

The cigarette holder 100 needs to be installed in the metal main bracket 312 , so it is preferably a ring structure, and the inner diameter of the metal main bracket 312 matches the outer circumference of the cigarette holder 100 . Of course, other structures such as square or rhombus can also be designed.

The metal main bracket 312 can be made of copper, of course, other metal materials that can withstand the temperature of the heating flue gas, such as titanium or copper-tungsten alloy, are also possible. In addition, the metal main support 312 is preferably configured as a porous structure to facilitate the circulation of smoke during the heating process.

In order to make the cigarettes heated evenly, the electromagnetic heating body 314 is preferably arranged at the center of the metal main bracket 312 . Of course, the object of the present invention can also be achieved without the central location, all within the protection 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.

According to the principle of electromagnetic induction, the material of the electromagnetic heating body 314 can be iron. Of course, other magnetically permeable materials such as carbon steel and stainless steel are also possible.

In order to facilitate deep cleaning of the electromagnetic heating body 314 , the electromagnetic heating body 314 can be detachably connected to the metal main bracket 312 through the third permanent magnet 530 .

It should be noted that to realize electromagnetic induction heating, a magnetic induction coil 322 needs to be arranged around the electromagnetic heating body 314 to provide an alternating magnetic field, and the electromagnetic heating body 314 and the magnetic induction coil 322 should be separated by a certain distance. For this reason, the magnetic induction coil 322 can be wound on the outside of the heat insulation layer 323 of the heating cavity 320, which can avoid direct contact between the smoke and the magnetic induction coil 322, thereby preventing the harmful substances in the smoke from adhering or corroding the magnetic induction coil 322 . At the same time, the temperature outside the heat insulation layer 323 is lower, which can further reduce the damage of the high-temperature flue gas to the magnetic induction coil 322 , thereby prolonging the service life of the magnetic induction coil 322 .

Of course, it is also possible to wind the magnetic induction coil 322 on the inner side of the heat insulation layer 323, the outer side of the inner wall 324, etc., as long as the electromagnetic heating body 314 is in the alternating magnetic field emitted by the magnetic induction coil 322, it is all within the protection scope of the present invention.

In addition, the electric rod assembly 400 is provided with a circuit and a control component for supplying an alternating current to the magnetic induction coil 322 .

In order to make the inside and outside of the cigarette holder 100 evenly heated, a heating ceramic sleeve 311 is provided on the outside of the metal main bracket 312 , and the two can be detachably connected by a positioning nut 313 . In addition, the fixing position of the heating ceramic sleeve 311 on the metal main bracket 312 can be changed by adjusting the positioning nut 313 , thereby changing its heating position for the cigarette 100 . Of course, the number of heating ceramic sleeves 311 is not limited to one, and can be adjusted as required.

An annular heater 200 for heating the solid extract 234 and the tobacco particles 235 is also provided outside the metal main support 312 . For this reason, a groove protruding from the outer wall of the metal main support 312 may be provided on the upper part thereof for placing the ring heater 200 . In order to facilitate the operation of the ring heater 200 , it is preferably arranged on the upper part of the metal main support 312 .

The solid extract is specifically prepared by adding a certain amount of sodium alginate to the extract, and then adding Ca ²⁺ ions for reaction, or other gel materials can also be added.

In the use of the above structure, when using the electromagnetic heating body 314 to heat the cigarette 100, first insert the cigarette 100 into the metal composite sleeve 310, so that the electromagnetic heating body 314 is inside the cigarette 100; Components, such as opening the magnetic induction switch 450 of the electric rod assembly 400, and then the alternating current is passed into the electromagnetic induction coil 322, and the electromagnetic induction coil 322 generates an alternating magnetic field immediately; the electromagnetic heating body 314 located in the alternating magnetic field generates heat due to electromagnetic induction, and then The heat is conducted to the cigarette 100 in contact with it, so as to realize the heating of the cigarette 100 from the inside.

When using the heating ceramic sleeve 311 to heat the cigarette 100, turn on the control circuit in the electric rod assembly 400 to energize the heating ceramic sleeve 311, the heating ceramic sleeve 311 generates heat under the action of the current, and heats the cigarette 100 from the outside .

When using the ring heater 200 to heat the solid extract 234 and the tobacco particles 235, at first the ring heater with the solid extract 234 and the tobacco particles 235 is placed in the groove of the metal main support 312, and then the control in the electric rod assembly 400 is opened. The electric circuit realizes the conduction between the ring heater 200 and the metal main support 312 , and further realizes the heating of the solid extract 234 and the tobacco particles 235 .

It can be seen that the metal composite sleeve 310 is equipped with an electromagnetic heating body 314 that uses the principle of electromagnetic induction to heat the cigarette 100 , and the metal composite sleeve 310 is equipped with a ceramic heating sleeve 311 that heats the cigarette 100 . In addition, an annular heater 200 for heating the solid extract 234 and the tobacco particles 235 is provided outside the metal composite sheath 310 . The arrangement of the electromagnetic heating body 314, the ceramic heating sleeve 311 and the ring heater 200 can provide users with different heating methods, thereby realizing heating the cigarette 100, heating the solid extract 234 and the tobacco particles 235, heating the cigarette 100 and Various suction functions such as heating solid extract 234 and tobacco particles 235 compounding.

For example, during the smoking process, the cigarette holder 100 can be fixed in the metal main bracket 312, and the cigarette holder 100 can be heated by the electromagnetic heating body 314 or the ceramic heating sleeve 311 alone, or the electromagnetic heating body 314 and the ceramic heating sleeve can also be used. The tube 311 heats the cigarette at the same time, thereby realizing the smoking experience of the cigarette 100; or it is separately filled with the ring heater 200 containing the solid extract 234 and tobacco particles 235, and the solid extract 234 is heated by the ring heater 200. Tobacco particles 235 are heated to realize the smoking experience of solid extract 234 and tobacco particles 235; of course, the cigarette 100, solid extract 234 and tobacco particles 235 can be loaded at the same time, and the electromagnetic heating body 314, ceramic The heating sleeve 311 and the ring heater 200 are heated to obtain a combined smoking experience of the cigarette 100, the solid extract 234 and the tobacco particles 235. Obviously, by separately or combining the cigarette 100 and the ring heater 200, it is possible to separately heat the cigarette 100 or the solid extract 234 and the tobacco particles 235 to achieve a different smoking experience, and it is also possible to heat the cigarette 100 and the solid extract 234 Combined with tobacco particles 235 to experience the function of smoking.

In addition, because the principle of electromagnetic heating itself has the advantages of quick thermal start and high thermal efficiency, the preheating time for the electromagnetic heating body 314 to heat the cigarette 100 alone is shorter. The heating ceramic sleeve 311 and the electromagnetic heating body 314 heat the cigarette at the same time, so that the inside and outside of the cigarette 100 are heated evenly, thereby providing a more uniform smoke and providing a better smoking experience for the user. It can be seen that the different heating methods of the electromagnetic heating body 314 and the ceramic heating sleeve 311 also have different suction experiences.

To sum up, in the heating smoking appliance provided by the present invention: on the one hand, there are different smoking experiences provided by different heating methods of the cigarette 100 and the ring heater 200 alone or in combination; Different pumping experiences provided by heating methods. It can be seen that the heating smoking utensil provided by the present invention has a variety of heating methods, provides users with rich smoking experience functions, greatly meets the different needs of users for smoking experience, and solves the problem of low-temperature heating smoking utensils in the prior art. The problem of single suction experience caused by a single heating method.

On the basis of the above embodiments, in order to better realize 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 solid extract 234 and tobacco particles 235 includes a heating ceramic part 210 , a heat conducting shell 220 and a ring heating body 230 .

The material of the heat conduction shell 220 is preferably a non-porous metal material with high heat conduction, such as copper, copper alloy, etc., so as to realize efficient heat conduction between the metal main bracket 312 and the heat conduction shell 220 .

In order to cooperate with the metal main bracket 312 , the heat conduction shell 220 is preferably a ring structure, and its inner and outer circumference dimensions match the inner and outer circumference dimensions of the groove on the metal main bracket 312 .

An annular heating body 230 filled with solid extract 234 and tobacco particles 235 is placed in the heat conducting shell 220 . Certainly, the shape of the ring heating body 230 is preferably ring, and the inner and outer diameters of the ring should match the size of the inner and outer circumference of the heat conducting shell 220 .

A heating ceramic element 210 for heating the annular heating body 230 is also arranged on the heat conduction shell 220 , and of course other heating elements such as resistance wires can also be used.

In this embodiment, the heating ceramic part 310 heats the annular heating body 230 containing the solid extract 234 and the tobacco particles 235, and at the same time, since the heat conduction shell 220 is connected with the metal main support 312, the electromagnetic heating body 314 or the ceramic heating sleeve When the pipe 311 heats the cigarette 100 , the heat will inevitably be conducted to the heat conduction shell 220 through the metal main bracket 312 , and then further heat the annular heating body 230 . It can be seen that the heating of the solid extract 234 and the tobacco particles 235 in the annular heating body 230 is realized by the double heating method of the contact heat conduction between the heat conduction shell 220 and the metal main bracket 312 and the heating of the ceramic part 310, thus ensuring that the solid extract 234 and uniform heating and heating rate of the tobacco particles 235.

On the basis of the above embodiments, in order to better realize the storage of the solid extract 234 and the tobacco particles 235, the structure of the annular heating body 230 is limited in another embodiment.

The annular heating body 230 includes a heating aluminum box 231 , solid extract 234 , tobacco particles 235 , non-woven fabric 232 and sealing aluminum foil 233 . Among them, the heating aluminum box 231 is used to contain the solid extract 234 and tobacco particles 235, the non-woven fabric 232 is sealed at the opening of the heating aluminum box 231, and there is another layer of sealing aluminum foil 233 on the non-woven fabric 232.

When not in use, the sealing aluminum foil 233 is covered on the non-woven fabric 232 to realize effective sealing of the entire heating aluminum box 231; when in use, the sealing aluminum foil 233 is torn off to realize air suction and heating of the solid extract 234 in the aluminum box 231 and the flow of smoke generated by heating the tobacco particles 235, and at this time the non-woven fabric 232 can filter out macromolecules or particles in the smoke, making the smoke more comfortable to smoke.

It can be seen that the heating aluminum box 311 can realize the heat conduction between the heat conduction shell 220 or the heating ceramic part 210, the solid extract 234 and the tobacco particles 235; Smooth smoking experience, while filtering out impurities in the smoke, thereby providing a more comfortable smoking experience; while the sealed aluminum foil 233 mainly prevents the deterioration of the solid extract 234 or tobacco particles 235 inside the heated aluminum box 231 when not in use, Thereby avoiding the detrimental effect of deterioration on the pumping experience.

On the basis of the above embodiments, the heating ceramic element 210 can be installed inside the heat conducting shell to heat the annular heating body 230 .

The heating ceramic element 210 can be a heating ceramic knife or a heating ceramic needle, and is preferably disposed at the bottom of the heat conduction shell 220 .

During the heating process, the heat generated by heating the ceramic element 210 is directly transferred to the interior of the annular heating body 230 and diffused to the surroundings, so as to realize the heating of the solid extract 234 and the tobacco particles 235 inside the annular heating body 230 .

Since the heating ceramic part 210 is located at the bottom of the heat-conducting shell, when there is little solid extract 234 or tobacco particles 235 remaining, the heating ceramic part 210 at the bottom can fully heat it, thereby reducing material waste.

On the basis of the above embodiments, since the heating ceramic part 210 is heated from the inside of the annular heating body 230, the internal temperature of the annular heating body 230 is higher than the external temperature. In order to make the inside and outside of the heating evenly, in another embodiment, The heat conduction shell layer 220 is made of magnetically conductive non-porous metal material.

The thermally conductive shell 220 may be a magnetically conductive non-porous metal material, such as carbon steel, iron, and the like.

During the use of the smoking appliance, the electromagnetic heating switch and the electric heating switch can be turned on at the same time. Since the heat conduction shell 220 and the electromagnetic heating body 314 are in the changing magnetic field provided by the magnetic induction coil 322 , heat will be generated due to electromagnetic induction. Wherein, the heat conducting shell 220 is heated from the outside of the annular heating body 230 , and the heating ceramic element 210 is heated from the inside of the annular heating body 230 , and the cooperation of the two makes the inner and outer heating of the annular heating body 230 uniform.

It should be noted that electromagnetic heating has the advantages of fast start-up and high thermal efficiency, so the use of the heat-conducting shell 220 and the magnetically conductive non-porous metal material can also reduce the preheating time of the annular heating body 230 and realize its efficient heating.

Based on the above embodiments, the heating ceramic element 210 may be installed outside the heat conducting shell 220 .

The heating ceramic element 210 may be a heating ceramic tube, which is sleeved on the outside of the heat conducting shell 220 . Certainly, the heating resistance wire may also be wound on the outside of the heat conducting shell 220 .

During the heating process, on the one hand, the heating ceramic part 210 heats the annular heating body 230 from the outer periphery of the heat-conducting shell 220; .

It should be noted that since the outer periphery of the heat conduction shell 220 is far away from the metal main bracket 312, it receives less heat from the contact heat conduction of the metal main support 312, and the heating ceramic part 210 is installed on the outer periphery of the heat conduction shell 220 The upper part just makes up for the above-mentioned shortcomings, so that the inner and outer sides of the annular heating body 230 are evenly heated, thereby providing users with a better suction experience.

On the basis of the above embodiments, in order to increase the heat conduction effect of the heat conduction shell 220, in another embodiment, the structure of the heat conduction shell 220 adopts a composite structure of high heat conduction non-porous metal material and gradient porous metal material.

The outer side of the heat conduction shell 220 is a non-porous metal material with high heat conduction, such as copper, copper alloy, etc., to spread heat around the annular heat conductor 230 faster, so as to realize the heating of the internal solid extract 234 and tobacco particles 235 .

The inner side of the heat conduction shell layer 220 is a gradient porous metal material, such as a gradient porous copper material. Among them, the solid extract 234 and the tobacco particles 235 penetrate into the porous structure during the heating process, so that the contact specific surface area between the solid extract 234 and the tobacco particles 235 and the heat-conducting shell 220 is greatly increased, so as to facilitate the generation of smoke, and provide a convenient way for consumption. Provides a better suction experience.

On the basis of any one of the above embodiments, in order to further enhance the heat insulation effect of the smoking appliance, an air channel 325 may be added to the shell of the heating cavity 320 .

The shell structure of the heating chamber 320 can be arranged from outside to inside as an outer shell 321 , a heat insulating layer 323 and an inner wall 324 , wherein the inner wall wraps the space for heating cigarettes.

An air passage 325 for air circulation can be provided between the heat insulation layer 323 and the inner wall 324, one end of the air passage 325 communicates with the outside air, and the other end communicates with the smoke inside the heating cavity 320, and the air passage 325 The air flow direction in 325 is opposite to the smoke generation direction inside the heating cavity 320 . For example, the inlet of the air channel 325 may be located on the outer shell layer 321 , penetrating through to the flue gas inside the heating cavity 320 .

During the suction process, external low-temperature air enters the heating chamber 320 through the air channel 325 , and further cooling of the heat insulation layer 323 and the inner wall 324 is realized during the flowing process. In addition, because the heat transfer effect of the gas is poor, the air channel 325 can further block the diffusion of internal heat to the outside, improve the heat insulation effect of the smoking appliance, and thereby reduce the temperature of the outer wall of the smoking appliance.

It should be noted that since the air passage 325 communicates with the inside of the heating chamber 320, the external low-temperature air enters the interior of the heating chamber 320 through the air passage 325 and then mixes with the high-temperature flue gas inside, which reduces the temperature of the smoked gas and avoids Burning mouth caused by excessive smoke temperature increases the ease of smoking experience.

In this embodiment, the upper part of the heating chamber 320 may be provided with a suction nozzle 330 for easy suction. The suction nozzle 330 is actually equivalent to the extension of each part of the shell of the heating chamber 320, that is, the shell layer 321, the heat insulation layer 323, the inner wall 324 and the air channel 325 of the two are connected respectively, and finally tapered into a suction nozzle shape, which is convenient for users Suction of fumes.

In order to facilitate the cleaning and maintenance of the internal components of the heating cavity 300 , the suction nozzle 330 may be detachably fixed in the heating cavity 320 body. For example, the suction nozzle 330 and the main heating chamber 320 are connected through the second permanent magnet 520 . Certainly, other fixing methods such as clamping or threaded buckles may also be used.

In order to further reduce harmful substances in the smoke, a nozzle stick 600 for filtering smoke may be placed at the end of the suction nozzle 330 .

Considering the diverse needs of consumers for vaping experience, popping beads or incense sticks can be set in the above-mentioned mouth stick 600. It should be noted that the popping beads and incense sticks can be provided with various flavors to provide consumers with rich choices.

On the basis of the above-mentioned embodiments, considering that the demand for smoking cigarettes 100 of different specifications can be met by replacing the metal composite sheath 310, in another embodiment, the metal composite sheath 310 is detachably connected to the heating cavity 320 .
