Referring to fig. 1 and fig. 2, fig. 1 is an exploded perspective view of a heating module 100 according to an embodiment of the present disclosure. Fig. 2 is a partial sectional view of a heating module 100 according to an embodiment of the present application. The heating module 100 provided herein may be used in a smoking device. By smoking device is meant a smoking aid accessory for a user to smoke a smoking article.

The heating module 100 includes a base 10, a heating element 20 disposed on the base 10, and a smoking cup 30 disposed at an end of the heating element 20 away from the base 10. A connector 40 is arranged between the heating element 20 and the smoking cup 30. A bracket 50 is disposed between the base 10 and the heat generating component 20. The heating module 100 further comprises a housing 60, wherein the housing 60 is fixed on the base 10 and covers the heating element 20, the cup 30, the connector 40 and the bracket 50. A cavity 100a is formed between the heating element 20, the cup 30 and the housing 60. Chamber 100a the chamber 100a is filled with an insulation assembly 70.

The carrying bracket 50, the heating element 20, the connector 40, the bowl 30 and the housing 60 are in turn mounted on the base 10. The base 10 is provided with a fixing portion of the holder 50 and the housing 60. In the present embodiment, the base 10 is provided with a plurality of insertion holes 11 for fixing the bracket 50 and a stepped fixing portion 12 for fixing the housing 60. The base 10 can be made of plastic, the plastic material has a low thermal conductivity coefficient, and the high-temperature resistant plastic material has the effects of heat preservation and heat insulation while meeting the use requirements. In addition, the base 10 is further provided with an air inlet for air to enter the heating module 100.

The heat generating component 20 includes a heat generating body 21 and a heat conductor 22. The heat conductor 22 has a receiving cavity 22 a. The heating element 21 is accommodated in the accommodating chamber 22 a. The receiving cavity 22a may be a blind hole or a through hole opened in the heat conductor 22. In one embodiment, the heat conductor 22 and the accommodating chamber 22a are both cylindrical, and the heat conductor 22 is disposed coaxially with the accommodating chamber 22a, so that the heat transferred from the heating body 21 to the heat conductor 22 is uniform. In addition, a plurality of air passages 23 are formed in the heat conductor 22. The air passage 23 extends along an end of the thermal conductor 22 opposite the base 10 to an end of the thermal conductor 22 opposite the bowl 30 for directing air from the base 10 to the bowl 30.

The heating element 21 may be a resistance heating wire. The resistance heating wire has a spiral main body 211 and two current-carrying ends 212 connected to the main body 211. The two power terminals 212 can pass through the openings on the base 10 to connect with the power module. The heat conductor 22 is a core component for performing heat exchange and heating air in the heat generating component 20, and a material with a high thermal conductivity can be used. The heat conductor 22 has a small volume and a large contact area with air, so that the heat convection process with air can be sufficiently completed. The material of the heat conductor 22 can be selected from: sintered bodies of materials such as alumina, zirconia, and silicon nitride; metallic materials may also be selected, such as: aluminum, copper, iron, and other metal materials. When the heat conductor 22 is made of a metal material, the surface of the heat conductor 22 needs to be insulated to prevent the heat generating body 21 from short-circuiting when the heat conductor 22 contacts the heat generating body 21.

The bowl 30 is a container for the vaporization medium and is used to carry or hold the vaporization medium. The evaporation medium may be, for example, cigarette 1000 or cut tobacco, etc. A portion of the heat of the heating element 20 is transmitted to the cup 30 through the connector 40, which acts to bake the cigarette 1000 and promote the release of nicotine from the cigarette 1000. The cup wall of the smoking cup 30 is thin, and the volume is small so as to reduce the weight of the smoking cup. In one embodiment, the thickness of the walls of the smoking cup 30 is 0.1 mm to 0.5 mm. In a particular embodiment, the walls of the bowl 30 have a thickness of 0.15 mm to 0.2 mm. In a specific embodiment, the thickness of the walls of the bowl 30 is 0.2 mm. The cup 30 may be shaped and sized to correspond to a cigarette rod, such as being cylindrical. The inner diameter of the cup 30 and the length of the cup 30 are required to correspond to the length of a cigarette so that the cup 30 surrounds the outer periphery of the tobacco portion of the cigarette. For example to correspond to a tobacco rod in femoni, in one embodiment the cups are 12.5 cm in length and 7.35 mm in diameter. The materials of the cigarette cup 30 can be selected from: metals such as stainless steel, etc., ceramics, etc., which have a high thermal conductivity. To function as an auxiliary heating, in some embodiments, the material of the bowl 30 comprises a metal or alloy material, such as aluminum, copper, stainless steel, etc., or a ceramic material.

The connector 40 is used to connect the bowl 30 and the heating element 20 together. Specifically, the connector 40 has one end in direct contact with the heating element 20 and the other end in direct contact with the bowl 30. Referring to fig. 3, the connector 40 includes a mounting platform 41 and a limiting portion 42 disposed on a side of the mounting platform 41 facing the smoking cup 30. The bowl 30 is mounted on the mounting block 41. The mounting block 41 is substantially in the form of a hollow circular ring. An opening or cutout in the middle of the mounting plate 41 is positioned to allow air to flow from the heating element 20 to the bowl 30. A receiving cavity 41a is formed in the mounting platform 41, and one end of the heating element 20 is received in the receiving cavity 41 a.

The limiting part 42 is disposed along the periphery of the mounting platform 41 and extends into the cigarette cup 30 to limit the depth of the cigarette 1000 inserted into the cigarette cup, so as to adjust the distance between the evaporation medium and the heating assembly 20 to control the heating temperature of the evaporation medium. The stop 42 serves to limit the depth of insertion of the evaporative medium into the bowl 30. The distance h between the surface of the limit part 42 far away from the heating element 20 and the surface of the heating element 20 close to the cigarette cup 30 is larger than 1mm and smaller than 5 mm. When the distance h between the cigarette 1000 and the heating component 20 is less than 1mm, the cigarette 1000 is easy to generate burnt smell because of being too close to the heating component 20; when the distance h between the cigarette 1000 and the heating element 20 is greater than 5mm, the air heated by the heating element 20 is not sufficiently attenuated by temperature to atomize the cigarette 1000. Therefore, the distance between the cigarette 1000 and the heating element 20 should be greater than 1mm and less than 5 mm.

The shape of the stopper portion 42 is not limited in the present application. In the present embodiment, the stopper portion 42 includes a plurality of stopper posts 421 provided at intervals along the outer periphery of the mount table 41.

In other words, the first surface 42a of the limiting portion 42 and the upper surface of the mounting platform 41 form a step-shaped fixing portion, and the smoking cup 30 is fixed on the fixing portion. Specifically, in the present embodiment, the outer surfaces of the plurality of stopper columns 421 away from the accommodating cavity 41a jointly constitute the first surface 42 a.

In another embodiment, for example, a projection may be provided on the surface of the stopper 42, a recess may be provided in the cup 30, and the stopper 42 and the cup 30 may be fixed by fitting the projection on the surface of the stopper 42 into the recess in the cup 30.

Firstly, the function of supporting the cigarette cup 30 and fixing and positioning the heating component 20 together with the bracket 50; secondly, the cigarette cup 30 and the heating component 20 are connected together to conduct part of heat of the heating component 20 to the cigarette cup 30, and the temperature of the cigarette cup 30 is increased to facilitate the atomization of the cigarettes 1000 and release nicotine; thirdly, the limiting part 42 on the connector 30 can be used for controlling the insertion depth of the cigarette 1000 and controlling the distance between the cigarette 1000 and the heating component 20, the heat conduction coefficient of the connector 40 is smaller than that of the heating component 20 and the cigarette cup 30, meanwhile, the connector 40 is in bone position contact with the cigarette cup 30 and the heating component 20, the contact area is minimized, the conduction of the heat of the heating component 20 to the cigarette cup 30 is reduced to the maximum extent, most of the heat of the heating component 20 is used for heating air, and the small part of the heat is conducted to the cigarette cup 20 to keep the temperature of the cigarette cup 20.

Referring to fig. 4(a), in other embodiments of the present application, the stopper 42 is not used for fixing the cup 30. The limiting part 42 is arranged at intervals with the inner wall of the cigarette cup 30. The mounting table 41 is further provided with a fixing portion 44, and the cup 30 is fixed to the mounting table 41 by the fixing portion 44. The fixing portion 44 may include a plurality of fixing posts 441 spaced along the outer circumference of the mounting table 41, like the stopper portion. The retainer 44 may also be other structures and locations, such as a groove for engaging a protrusion provided on the wall of the bowl 30. Are not listed here.

The connector 40 is further provided with a limiting groove 43, and an end of the heating element 20 abuts against the limiting groove 43 to limit the position of the heating element 20. In the present embodiment, the stopper groove 43 may be opened in the stopper portion 42. Specifically, the stopper groove 43 may be opened on the inward side of the stopper portion 42. The retaining groove 43 may include a first retaining surface 431 and a second retaining surface 432. The first and second stop surfaces 431, 432 are substantially perpendicular. The first stopper surface 431 is parallel to and abuts against the top surface of the heat conductor 22, and the second stopper surface 432 is parallel to and abuts against the peripheral side surface of the heat conductor 22.

Referring to fig. 4(b), in another embodiment of the present application, the limiting groove 43 may also be opened on the mounting table 41. The first and second stopper surfaces 431 and 432 are located on a side of the mount table 41 away from the stopper portion 41.

The bracket 50 functions to support the heating element 20 and the bowl 30. The bracket 50 also fixes the heat generating component 20 together with the connector 40. The bracket 50 includes a supporting platform 51 and a plurality of positioning posts 52 spaced apart from each other on the supporting platform 51 and near the heating element 20. The holder 50 is substantially in the form of a hollow circular ring. The opening or cutout in the center of the bracket 50 is used for air to flow to the heat generating component 20 and for the two power terminals 212 to pass through to connect with the power module. A plurality of positioning posts 52 are provided around the periphery of the support table 51. The heating element 20 is fixed to the support base 51, and a part of the bottom surface of the heating element 20 abuts against the support base 51. The heat generating component 20 is sandwiched between the positioning posts 52. Specifically, the outer peripheral wall of the heat generating component 20 abuts against the inner side wall of the positioning column 52. The positioning posts 52 only sandwich the end of the heat generating component 20.

The bracket 50 further includes a plurality of first fixing members 53 disposed on a side of the supporting platform 51 adjacent to the base 10. The base 10 is provided with a second fixing member 11 engaged with the first fixing member 53. The first fixing member 53 is fitted to the second fixing member 11 to fix the holder 50 to the base 10. The first fixing member 53 and the second fixing member 11 may be a pin and a socket. In the present embodiment, the first fixing member 53 includes a plurality of latches. The second fixing member 11 includes a plurality of insertion holes 11. The base 10 and the bracket 50 are contacted through a few small points, so that the contact area is small, and the heat loss of conduction heat conduction is reduced. However, the connection between the bracket 50 and the base 10 is not limited thereto.

The material of the bracket 50 is high temperature resistant material such as zirconia ceramics, silica, ceramics, etc. It can reduce conduction heat conduction, reduce heat loss. The use of several bone positions and a smaller contact surface to hold the heating element 20 further reduces the heat loss from conductive heat conduction.

The housing 60 may be hollow cylindrical. The peripheral wall of the housing 60 is locked to the stepped fixing portion 12 of the base 10. The housing 60 has a vent hole 62 formed in an outer wall thereof. The vent 62 is located at an end of the housing 60 proximate the base 10. The shell 60 can be made of plastic, the plastic material has the characteristic of low heat conductivity coefficient, and the high-temperature resistant plastic material has the effects of heat preservation and heat insulation while meeting the use requirement. The contact area between the shell 60 and the cigarette cup 30 is small, and the contact area between the shell 60 and the base 10 is small, so that the heat loss caused by conduction heat conduction is reduced.

The temperature of the heat conductor 22 of the heating element 20 during operation can reach 400 ℃, and therefore, heat preservation and insulation measures become important. In one embodiment, insulation assembly 70 includes a first insulation assembly 71 and a second insulation assembly 72.

The glass fiber has good heat resistance, very low heat conductivity and good flame retardance, and is a nontoxic and harmless material without generating peculiar smell at high temperature. In one embodiment, glass fiber is selected as the thermal insulation material. Glass fibers are wrapped and filled between the shell 60 and the smoke cup 30 and between the shell 60 and the heating component 20, and the glass fibers are wrapped on the most core working component heat conductor 22 of the heating component 20, so that on one hand, heat released by the heating component 20 can be wrapped, and the working efficiency of the heating component 20 is improved; on the other hand, the heat can be effectively organized to diffuse and run off to the shell 60 in a radiation mode, the working efficiency of the heating body can be effectively improved, the heat loss is effectively reduced, and the temperature rise of the shell is reduced.

Referring to fig. 5, in other embodiments, the first thermal insulation assembly 71 includes a first thermal insulator 711 and a first heat reflector 712. The first heat reflector 712 is disposed between the first heat insulator 711 and the case 60. The second thermal insulation assembly 72 includes a second thermal insulator 721 and a second heat reflector 722. The second heat reflector 722 is disposed between the second thermal insulator 721 and the case 60. In some embodiments, first insulation assembly 71 and second insulation assembly 72 may also be a split structure. The first thermal insulator 711 and the second thermal insulator 721 may be separate structures, and the first thermal reflector 712 and the second thermal reflector 722 are also separate structures, which are not described herein again. The heating module of the present embodiment arranges the first heat insulation assembly 71 in the first heat insulation chamber 100a formed between the heat generating assembly 20 and the case 60, the first heat insulation assembly 71 includes a first heat insulator 711 and a first heat reflector 712, and the first heat reflector 712 is located between the first heat insulator 711 and the case 60. In the embodiment, the first heat insulator 711 is provided to reduce the heat loss of the heat generating component 20, so as to improve the working efficiency of the heat generating component 20, and the first heat reflector 712 is provided outside the first heat insulator 711, so that the first heat reflector 712 can re-reflect the radiant heat energy transmitted through the first heat insulator 711 to the first heat insulator 711, and further, the heat loss of the heat generating component 20 can be greatly reduced by using the first heat insulator 711 and the first heat reflector 712 in a matching manner. In addition, the above arrangement reduces the temperature of the housing 60 and promotes comfort of use of the smoke generating device.

Further, the present embodiment is provided with the second heat insulation assembly 72 disposed in the second heat insulation cavity 100b formed between the smoking cup 30 and the housing 60, wherein the second heat insulation assembly 72 includes the second heat insulator 721 and the second heat reflector 722, and the second heat reflector 722 is located between the second heat insulator 721 and the housing 60, so that, through the cooperation of the second heat insulator 721 and the second heat reflector 722, the heat loss of the smoking cup 30 is reduced, so that the smoking article in the smoking cup 30 can be sufficiently heated by the hot air entering the smoking cup 30, thereby facilitating to improve the atomization efficiency of the smoking article, so that the smoker can timely smoke the smoking article.

In the present embodiment, the first heat reflector 712 is an aluminum foil. In particular, the first heat reflector 712 is a web of aluminum foil. The aluminum foil coil is coated on the periphery of the porous heat insulation material.

Specifically, the aluminum foil has good ductility, low self-thermal resistance, and low absorption rate of radiant heat energy, and in addition, 80% to 95% of heat energy can be reflected to the first heat insulator 711 due to the smooth surface of the aluminum foil. Therefore, in the present embodiment, the porous heat insulating material and the aluminum foil are used in combination, so that the heat loss in the heat conductor 22 can be greatly reduced, and the working efficiency of the heat conductor 22 can be further improved. In addition, the above arrangement further reduces heat loss in the bowl 30, thereby further enhancing the use of the smoke generating device.

In the present embodiment, since the heat conductor 22 is in contact with the bracket 50, in order to prevent the heat in the heat conductor 22 from being transferred to the support base 51, the first thermal insulator 711 is further disposed between the housing 60 and the bracket 50, so that the heat loss in the heat conductor 22 can be further reduced.

Referring to fig. 5, in some embodiments, the first insulator 711 is a heat shield. The heat shield is sleeved on the outer periphery of the heat conductor 22 and the smoke cup 30. The material of the heat shield can include fiberglass, aerogel, etc.

The first heat reflector 712 is a heat reflective film. The heat reflective film is attached to the outer peripheral wall of the heat shield. Specifically, the heat reflection film may be a metal film such as gold, silver, or nickel, or a film material capable of reflecting radiant heat energy such as a polyester or polyimide film plated with a metal material.

It is understood that the heat reflective film reflects heat energy better than the aluminum foil coil because of the high surface flatness of the film material, especially the high smoothness of the film layer surface of the metal film. When a small amount of radiant heat energy penetrating through the heat shield is transmitted to the surface of the heat reflection film, most of the heat energy can be reflected to the heat shield again, so that the probability of transmitting the heat energy to the shell 60 is greatly reduced, and a better heat preservation and insulation effect can be achieved on the heat conductor 22 and the cigarette cup 30.

Specifically, a heat reflection film may be formed on the outer peripheral wall of the heat shield by an electroplating process or a sputtering process, and then the heat shield to which the heat reflection film is attached is directly sleeved on the outer peripheral sides of the heat conductor 22 and the heat cup 30 in the assembling process of the heating module 200, so as to achieve a dual heat insulation effect, thereby effectively reducing the heat loss of the heat conductor 22 and the heat cup 30.

Furthermore, since the heat shield has a better heat insulation effect on heat energy, and the heat reflection film has a better reflection effect on heat energy, under the condition that the internal spaces of the first heat insulation cavity 100a and the second heat insulation cavity 100b are fixed, the heat loss of the heat conductor 22 and the smoke cup 30 can be minimized while the radiation heat loss is reduced by adjusting the thickness of the heat shield and the thickness of the heat reflection film.
