Description

Heating devices and heat-not-burn smoking devices Technical Field

[0001] The utility model relates to the technical field of heat-not-burn smoking articles, in particular to a heating device and a heat-not-burn smoking article. Background Art

[0002] Aerosol-generating substrates typically produce the desired aerosol at temperatures below combustion. This heating method is typically performed using heat-not-burn (HBN) devices, which typically heat the aerosol-generating substrate circumferentially through a tubular heating structure. To ensure more efficient heating, conventional HNB devices typically employ a high proportion of heating elements around the circumference of the tubular heating structure. This results in excessively high heating temperatures, which in turn produces an aerosol that is too hot to meet user needs. Utility Model Content

DETAILED DESCRIPTION

[0023] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0024] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0025] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0026] The present application provides a heating device and a heat-not-burn smoking device. The heating device is applied to the heat-not-burn smoking device. The heating device can heat the aerosol generating substrate to a temperature at which the aerosol generating substrate can generate aerosol but is not high enough to burn, thereby allowing the aerosol generating substrate to generate the aerosol required by the user.

[0027] Generally, in order to make the aerosol generating substrate heated more evenly, the heating method of the heating device in the heat-not-burn smoking device is to heat the aerosol generating substrate circumferentially, and the heating area occupies a higher area ratio on the heating device. After the heat-not-burn smoking device is started to heat the aerosol generating substrate, the temperature generated by the heating device will be too concentrated, thereby generating an aerosol with too high a temperature.

[0028] During the process of high-temperature heating of the aerosol generating matrix, the aerosol generated by the aerosol generating matrix can be released from the aerosol generating matrix through the evaporation of water vapor from the external gas. Excessively high temperature will evaporate a large amount of water vapor, thereby making the temperature of the generated aerosol too high, thereby forming an aerosol that is difficult to meet the temperature required by the user.

[0029] In the present application, the heating device adopts a zoned heating method, two heating zones of different areas are set on the circumference of the heating device, and the aerosol generating matrix is ​​heated in batches, and only a small amount of water vapor is evaporated each time, thereby reducing the water vapor content in the released aerosol mixed with water vapor, and the temperature of the aerosol can be relatively reduced.

[0030] 1 and 2 , the heat-not-burn smoking device provided in this embodiment includes: a heating device 10 , a heat exchange structure 20 , a flow guider 30 , an inner shell 40 , a power supply 50 , a circuit board 60 , a connecting component 70 , a switch 80 and an outer shell 90 .

[0031] An installation cavity 91 is provided inside the housing 90 for installing other components of the heat-not-burn smoking device.

[0032] The heating device 10 is mounted inside the inner shell 40, and an insertion port 92 is provided on the outer shell 90. The aerosol-generating substrate 100 can be inserted into the inner shell 40 through the insertion port 92 and contact the heating device 10. Because the heating device 10 can heat the aerosol-generating substrate 100 in a circumferential heating manner, the heating device 10 can be a hollow tubular structure, a needle-shaped structure, or a rod-shaped structure. When the heating device 10 is a hollow tubular structure, the aerosol-generating substrate 100 can be inserted into the interior of the heating device. When the heating device 10 is a needle-shaped structure or a rod-shaped structure, the heating device 10 is inserted into the center of the aerosol-generating substrate 100. In both cases, the aerosol-generating substrate 100 can be heated.

[0033] In this embodiment, the insertion of an aerosol-generating substrate 100 into the interior of a heating device 10 is used as an example. Specifically, a receiving chamber with openings at both ends is provided within the heating device 10, which is connected to an insertion port 92. In this embodiment, the insertion port 92 is coaxial with the receiving chamber. The aerosol-generating substrate 100 can be inserted into the receiving chamber through the insertion port 92, and the heating device 10 heats the aerosol-generating substrate 100 to generate an aerosol.

[0034] In a specific embodiment, one end of the accommodating chamber is open to allow the aerosol generating substrate 100 to be inserted into the accommodating chamber, and the other end of the accommodating chamber is open to allow ambient air to enter the accommodating chamber. During the heating process of the aerosol generating substrate 100 by the heating device 10, the ambient air evaporates to produce water vapor, which can carry out the aerosol generated by the heated aerosol generating substrate 100.

[0035] In the present embodiment, the aerosol generating matrix 100 includes: a matrix section 101, a cooling section 102 and a filtering section 103, wherein the matrix section 101 is connected to one end of the cooling section 102, and the other end of the cooling section 102 is connected to the filtering section 103. In some embodiments, the matrix section 101, the cooling section 102 and the filtering section 103 are coaxially connected. They can also be wrapped by a wrapping layer. Of course, it can also be considered that the matrix section 101, the cooling section 102 and the filtering section 103 wrapped by the wrapping layer are a monolithic structure. In a preferred embodiment, the aerosol generating matrix 100 is a columnar structure. The matrix segment 101 can generate aerosol under the action of heating. The matrix segment 101 is provided with an air inlet, which is connected to the outside world. External gas can enter the matrix segment 101 through the air inlet, generate high-temperature steam in a heated state, and bring the aerosol to the cooling segment 102 through the steam. The cooling segment 102 is provided with a cooling cavity, which is connected to the filtering segment 103. The cooling cavity can extend the gas passage path of the aerosol mixed with water vapor, thereby indirectly cooling the aerosol by extending the aerosol passage time, and filtering other gas impurities in the aerosol under the action of the filtering segment 103.

[0036] In the above embodiment, the matrix segment 101 is accommodated in the accommodating cavity of the heating device 10 and is heated by the heating device 10 .

[0037] The power supply 50 is connected to the heating device 10 through the circuit board 60 . The power supply 50 can provide electrical energy to the heating device 10 , and the circuit board 60 can control the amount of heat generated by the heating device 10 .

[0038] In one embodiment, the power source 50 is preferably a rechargeable battery. A charging port 93 is also provided on the housing 90, and the rechargeable battery can be charged by connecting to an external AC power source, so that the heat-not-burn smoking device can be recycled and carried easily.

[0039] In this embodiment, a switch 80 is further provided on the housing 90 , and the switch 80 can connect or disconnect the connection between the power source 50 and the heating device 10 .

[0040] In this embodiment, a reflective film 41 is further provided inside the inner shell 40. When the heating device 10 heats the aerosol generating matrix 100, the reflective film 41 can reflect the thermal radiation generated by the heating device 10 to avoid excessive heat being conducted to the outer shell 90 through the inner shell 40, thereby avoiding the outer shell 90 from being too hot and making it inconvenient to take the heat-not-burn smoking device.

[0041] The external gas enters the accommodating chamber through the bottom port of the heating device 10. A heat exchange structure 20 is provided below the bottom port of the heating device 10. The heat exchange structure 20 can exchange heat with the heating device 10 to heat the entering external gas. Through the cooperation between the heat exchange structure 20 and the heating device 10, the energy generated by the heating device 10 can be reduced.

[0042] A flow guide 30 is further provided between the heating device 10 and the heat exchange structure 20 , and the external gas heated by the heat exchange structure 20 can be guided to the aerosol generating matrix 100 through the flow guide 30 .

[0043] A connecting component 70 is also provided below the heat exchange structure 20, and the connecting component 70 includes: a middle connecting piece 71, a top connecting piece 72 and a bottom connecting piece 73. The middle connecting piece 71 is connected between the top connecting piece 72 and the bottom connecting piece 73. A connecting channel 721 is provided inside the top connecting piece 72, and the connecting channel 721 is connected to the heat exchange structure 20. The middle connecting piece 71 is provided with an air inlet 711 and an air outlet 712. The air outlet 712 is connected to the connecting channel 721. The bottom connecting piece 73 has an air inlet channel 731 inside, a filter element 732 is provided inside the air inlet channel 731, and a connecting port 74 is provided at the bottom of the air inlet channel 731.

[0044] In actual application, after the aerosol generating matrix 100 is inserted into the accommodating cavity of the heating device 10 through the insertion port 91, the aerosol generating matrix 100 is sucked so that the external gas enters the air inlet channel 731 through the connecting port 74. The filter element 732 can filter impurities from the external gas entering. The external gas after filtering out impurities enters the interior of the aerosol generating matrix 100 through the air inlet 711, the air outlet 712 and the connecting channel 721. At the same time, the connection between the power supply 50 and the heating device 10 is turned on by the switch 80, and the temperature of the heat generated by the heating device 10 is controlled by the circuit board 60, so as to heat the aerosol generating matrix 100. The water temperature in the external gas evaporates to form water vapor under high temperature environment, and the aerosol generating matrix 100 generates aerosol particles, which are brought out by the water vapor to form an aerosol.

[0045] 3 and 4 , the heating device 10 provided in this embodiment includes a heat conducting carrier 11 , a first heat generating component 12 and a second heat generating component 13 .

[0046] As shown in Figure 4 , the heat conducting carrier 11 is provided with a first heating zone 111 and a second heating zone 112 along its circumferential direction. The locations of the first heating zone 111 and the second heating zone 112 are roughly outlined in dashed lines in Figure 4 . The first heating component 12 is provided in the first heating zone 111 , and the second heating component 13 is provided in the second heating zone 112 .

[0047] It should be noted that the first heating component 12 is arranged throughout the first heating zone 111, and the second heating component 13 is arranged throughout the second heating zone 112. Both the first heating component 12 and the second heating component 13 can generate heat under the action of electrical energy. Specifically, the first heating component 12 and the second heating component 13 are connected to the power supply 50 via the circuit board 60. The power supply 50 provides electrical energy to the first heating component 12 and the second heating component 13, and the heat generated by the first heating component 12 and the second heating component 13 can be controlled via the circuit board 60.

[0048] The first heating component 12 and the second heating component 13 can be heated asynchronously or synchronously. In other words, while the first heating component 12 is being heated, the second heating component 13 is not being heated. Alternatively, while the first heating component 12 is being heated, the second heating component 13 is heated together with the first heating component 12. The heat generation of the first heating component 12 is less than or equal to the heat generation of the second heating component 13. The heat conducting carrier 11 can conduct the heat generated by the first heating component 12 and / or the second heating component 13 to the substrate segment 101 of the aerosol generating substrate 100, thereby heating the substrate segment 101 to generate aerosol.

[0049] In this embodiment, the first heat-generating component 12 and the second heat-generating component 13 are made of the same material with the same resistivity, and the first heat-generating component 12 occupies the entire first heat-generating zone 111, and the second heat-generating component 13 occupies the entire second heat-generating zone 112. Since the ratio between the area of ​​the first heat-generating zone 111 and the area of ​​the second heat-generating zone 112 is between 1 / 1 and 3 / 7, the heat generated by the first heat-generating component 12 is less than or equal to the heat generated by the second heat-generating component 13.

[0050] In actual applications, the first heating component 12 preheats the aerosol generating matrix 100, and then the aerosol generating matrix 100 is heated synchronously by the first heating component 12 and the second heating component 13. Since the heat output of the first heating component 12 is less than or equal to the heat output of the second heating component 13, the preheating process can evaporate some water molecules into water vapor. Compared with the previous method of heating the matrix segment 101 in the entire circumference, the water vapor content can be relatively reduced, thereby lowering the temperature of the aerosol. Afterwards, the second heating component 13 is heated synchronously with the first heating component 12. The first heating component 12 can play an auxiliary heating role. Heating together with the second heating component 13 can evaporate the remaining water molecules into water vapor. Similarly, the water vapor content can be relatively reduced, lowering the aerosol temperature.

[0051] As mentioned above, the heat-conducting carrier 11 can be a hollow tubular structure, a needle-shaped structure, or a rod-shaped structure. When the heat-conducting carrier 11 is a hollow tubular structure, the aerosol generating matrix 100 can be inserted into the interior of the heat-conducting carrier 11. When the heat-conducting carrier 11 is a needle-shaped structure or a rod-shaped structure, the heat-conducting carrier 11 can be inserted into the center position of the aerosol generating matrix 100. Both can achieve the function of circumferential heating of the aerosol generating matrix 100.

[0052] This embodiment is described using a heat-conducting carrier 11 having a hollow tubular structure as an example. The heat-conducting carrier 11 has a hollow accommodating chamber 113 with openings at both ends. The hollow accommodating chamber 113 is a receiving chamber. For ease of description, the openings at both ends of the heat-conducting carrier 11 are defined as a first opening 114 and a second opening 115, respectively. The first opening 114 communicates with the insertion port 92 on the housing 90, and the second opening 115 communicates with the communication channel 721 of the top connecting member 72. Thus, the aerosol generating substrate 100 can be inserted from the first opening 114 through the insertion port 92 into the hollow accommodating chamber 113. The hollow accommodating chamber 113 is used to accommodate the aerosol generating substrate 100. More specifically, the substrate segment 101 of the aerosol generating substrate 100 is inserted into the hollow accommodating chamber 113.

[0053] In this embodiment, the aerosol generating matrix 100 is a columnar structure. Therefore, the hollow accommodating chamber 113 is a columnar hollow chamber adapted for the columnar structure aerosol generating matrix 100, that is, the matrix segment 101 is inserted therein and the insertion port 92 maintains a coaxial relationship with the columnar hollow chamber.

[0054] During heating, the matrix segment 101 of the aerosol generating matrix 100 inserted in the hollow containing chamber 113 can be preheated for a period of time by the first heating component 12, and the matrix segment 101 of the aerosol generating matrix 100 inserted in the hollow containing chamber 113 can be heated synchronously by the first heating component 12 and the second heating component 13 that are heated synchronously.

[0055] During actual use, the aerosol generating matrix 100 is inserted into the hollow accommodating chamber 113 through the insertion port 92 and the first opening 112, so that the matrix segment 101 is located in the hollow accommodating chamber 113, and preheated for a first time by the first heating component 12. For example, preheating for 5 minutes by the first heating component 12 can evaporate part of the water into water vapor. Compared with the previous heating method, the water vapor content can be effectively reduced, thereby reducing the aerosol temperature. After being preheated for the first time by the first heating component 12, the second heating component 13 is heated synchronously with the first heating component 12. At this time, the first heating component 12 plays the role of auxiliary heating, and is heated together with the second heating component 13 to evaporate the remaining water into water vapor, relatively reducing the water vapor content and lowering the aerosol temperature.

[0056] It can be understood that in this embodiment, the heat conductive carrier 11 can be considered as a hollow tubular structure with a hollow channel, wherein a hollow accommodating chamber 113 is formed inside the hollow channel, and the two channel openings of the hollow channel are respectively formed as a first opening 114 and a second opening 115. The ratio of the area occupied by the first heating zone 111 on the circumferential surface of the heat conductive carrier 11 to the area occupied by the second heating zone 112 on the circumferential surface of the heat conductive carrier 11 is between 1 / 1 and 3 / 7, so that the heat generated by the first heating component 12 can be less than or equal to the heat generated by the second heating component 13.

[0057] Furthermore, it can be considered that the ratio between the heat generation of the first heat-generating component 12 and the heat generation of the second heat-generating component 13 is between 1 / 1 and 3 / 7.

[0058] During the heating of the matrix segment 101 by the first heating component 12, the amount of steam generated accounts for approximately half or 3 / 7 of the total steam amount. When the second heating component 13 is heated synchronously with the first heating component 12, approximately half or 4 / 7 of the steam amount can be generated. The two steam amounts are the same or different, thus forming a staged heating method. The steam will release heat after contacting the air. Since the amount of steam is reduced compared to the previous heating method, the heat released can be reduced, that is, the temperature of the aerosol is relatively reduced.

[0059] In one embodiment of the present application, the first heating component 12 and the second heating component 13 are not made of materials with the same resistivity. It is only necessary to ensure that the heating power of the first heating component 12 is less than or equal to the heating power of the second heating component 13, and the heating value of the first heating component 12 can also be less than or equal to the heating value of the second heating component 13.

[0060] In one embodiment, the heat conducting carrier 11 is a tubular structure, and the first heating zone 111 and the second heating zone 112 can be disposed on the inner wall, outer wall, or any area between the inner wall and the outer wall of the heat conducting carrier 11 .

[0061] When the first heating zone 111 and the second heating zone 112 are arranged on the inner wall or outer wall of the heat-conducting carrier 11, the first heating component 12 of the first heating zone 111 and the second heating component 13 of the second heating zone 112 can be insulated, for example, by covering with an insulating tube or coating with insulating material. The heat-conducting carrier 11 with a tubular structure can be a double-layer structure. In this way, the first heating zone 111 and the second heating zone 112 can be arranged between the double-layer structure of the heat-conducting carrier 11, that is, between the inner wall and the outer wall of the heat-conducting carrier 11. It can be understood that the double-layer structure can be set as a double-layer insulation structure to achieve insulation treatment of the first heating component 12 and the second heating component 13.

[0062] Continuing to refer to Figures 3 and 4, the first heat-generating component 12 is provided with a first electrode 120, the second heat-generating component 13 is provided with a second electrode 130, and a common electrode 140 is further provided between the first heat-generating component 12 and the second heat-generating component 13. The first electrode 120 and the second electrode 130 are used for the first pole of the external power supply, and the common electrode 140 is used for the second pole of the external power supply. The first heat-generating component 12 and the second heat-generating component 13 are connected in parallel through the common electrode 140.

[0063] It should be noted that the external power supply is the power supply 50, which provides power to the first heating component 12 and the second heating component 13. The first pole of the power supply is the positive pole or negative pole of the power supply, and the second pole of the power supply is the negative pole or positive pole of the power supply.

[0064] In this embodiment, a first lead 121 is further provided at the first electrode 120, a second lead 131 is further provided at the second electrode 130, and a common lead 141 is further provided at the common electrode 140. The first lead 121 and the second lead 131 are connected to the positive pole or negative pole of an external power supply, and the common lead 141 is connected to the negative pole or positive pole of the power supply, thereby connecting the first heat-generating component 12 and the second heat-generating component 13 to the power supply.

[0065] In the present application, the first heating component 12 is a first heating resistor arranged in the first heating zone 111, and the second heating component 13 is a second heating resistor arranged in the second heating zone 112, or the first heating component 12 is a first heating resistor coating printed on the first heating zone 111, and the second heating component 13 is a second heating resistor coating printed on the second heating zone 112, which is specifically set according to actual needs.

[0066] As described above, the first heating component 12 and the second heating component 13 are connected to the power supply 50 in parallel. The resistance value of the first heating component 12 is greater than or equal to the resistance value of the second heating component 13. According to p=U² / R, under the same voltage, the larger the resistance value, the smaller the heating power. Therefore, the heating power of the first heating component 12 is less than or equal to the heating power of the second heating component 13.

[0067] As shown in Figures 3 and 4, the first heating component 12 is bent and arranged in the first heating area 111, and the second heating component 13 is bent and arranged in the second heating area 112, so that the first heating component 12 covers the first heating area 111 and the second heating component 13 covers the second heating area 112.

[0068] In summary, the heating device and heat-not-burn smoking device provided in this embodiment preheats the substrate segment via the first heating component, evaporating some of the moisture into water vapor. Compared to conventional heating methods that utilize a relatively high percentage of the heating tube's circumference to heat the aerosol-generating substrate, this method effectively reduces the water vapor content, thereby lowering the aerosol temperature. After preheating by the first heating component, the second heating component is heated simultaneously with the first. At this point, the first heating component acts as an auxiliary heating element, working together with the second heating component to evaporate any remaining moisture into wet steam, thereby relatively reducing the water vapor content and lowering the aerosol temperature.

[0069] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
