Description

Technical Field

[0001] The present application relates to the field of heat-without-combustion technology, and in particular to a heating component and a heat-without-combustion device. Background Art

[0002] A Heat Not Burning (HNB) device heats tobacco products at a relatively low temperature (generally 250-350°C), heating the tobacco to form an aerosol for inhalation without burning it. Compared with traditional tobacco products that are heated and burned at temperatures above 800°C, a Heat Not Burning (HNB) device can minimize the harm caused by tobacco combustion, and the aerosol formed has a unique taste, so it is gradually gaining favor and attention from consumers.

[0003] In current heat-not-burn devices, the seal between the mounting tube and the mounting base is typically achieved using a clearance fit and a sealing ring. This fit is prone to tolerance fluctuations. In extreme cases, this can lead to overtightening, preventing the mounting tube from being properly seated, or oversizing, causing the sealing ring to interfere with the mounting base. In these cases, the mounting tube can easily become loose after vibration, creating a gap between the mounting base and the tube, thus failing to seal properly. This can lead to leakage of e-liquid into the heating element and corrosion of circuit board components. Utility Model Content

[0004] The purpose of this application is to provide a heating component and a heating without burning device to avoid the problem of oil leakage caused by failure of the seal between the fixed pipe and the mounting base.

[0005] The present application provides a heating component, which includes a heating tube, a fixed tube, a mounting cover and a mounting base. The heating tube has a heating cavity for accommodating an aerosol-forming substrate, and the heating tube is used to heat the side of the aerosol-forming substrate; the fixed tube is sleeved on the heating tube, the mounting cover is connected to the first end of the fixed tube, and the mounting base is connected to the second end of the fixed tube and the heating tube. The fixed tube, the mounting cover and the mounting base together form a mounting cavity, and the heating tube is located in the mounting cavity; wherein the second end of the fixed tube is connected to the mounting base by a thread.

[0006] Optionally, the mounting base includes a bottom core, a bottom platform and a bottom plate, and the bottom core, the bottom platform and the bottom plate are distributed in sequence along the direction away from the mounting cover, and the outer area of the bottom plate is larger than the outer area of the bottom platform, and the outer area of the bottom platform is larger than the outer area of the bottom core; the heating tube is connected to the bottom core, the outer side of the bottom platform is provided with an external thread, the inner side of the second end of the fixed tube is provided with an internal thread, and the second end of the fixed tube is connected to the bottom platform by a thread.

[0007] Optionally, the fixing tube abuts against the surface of the base plate.

[0008] Optionally, the junction between the base and the bottom plate is concave to form an annular groove, and the heating component further includes an annular sealing ring, which is arranged in the annular groove and surrounds the central axis of the base.

[0009] Optionally, the inner side of the annular sealing ring abuts against the side wall of the annular groove, and the outer side of the annular sealing ring abuts against the inner wall of the second end of the fixed tube.

[0010] Optionally, the internal thread and the external thread each have more than two turns.

[0015] The beneficial effect of the present application is that the present application adopts a threaded assembly method instead of a gap assembly method, so that the fixed tube and the mounting base are threadedly connected, which can effectively improve the situation where the assembly is too tight or too loose due to material tolerance fluctuations, resulting in improper assembly. As a result, when the heating tube heats the aerosol-forming matrix, the smoke generated will not escape from the connection between the fixed tube and the mounting base, thereby avoiding the failure of the sealing effect between the fixed tube and the mounting base, resulting in the leakage of smoke oil from the heating component and the corrosion of circuit board components.

DETAILED DESCRIPTION

[0025] The present application is described in detail below with reference to the accompanying drawings and optional embodiments. In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating relative importance or implicitly specifying the number of the technical features indicated. Therefore, unless otherwise specified, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0026] In addition, terms such as "top", "bottom", "inside", and "outside" indicating orientation or positional relationships are described based on the orientation or relative positional relationships shown in the accompanying drawings. They are only simplified descriptions for the convenience of describing this application, and do not indicate that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application.

[0027] It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Combine Figure 1 and Figure 2 As shown, an embodiment of the present application discloses a heat-not-burn device 10, which includes a shell 400 and a heating component 100, a control component 300 and a power supply 200 located in the shell 400. The control component 300 is electrically connected to the power supply 200 and the heating component 100, respectively, and controls the heating component 100 to heat the aerosol-forming matrix 20 to generate aerosol for human inhalation.

[0029] It should be noted that the aerosol-forming matrix 20 in the embodiment of the present application is solid, and specifically can be an aerosol generating rod. One end of the aerosol-forming matrix 20 is a suction end for inhaling aerosol, and the other end is inserted into the heating component 100. Aerosol can be generated by being heated by the heating component 100 without burning the aerosol-forming matrix 20.

[0030] Specifically, the housing 400 includes an inner bracket 600 and a mid-frame decorative member 500 positioned on the inner bracket 600. The housing 400 also includes panels on both sides of the inner bracket 600, which will not be described in detail here. The heating assembly 100, control assembly 300, and power supply 200 are connected to the inner bracket 600, while the switch 360 in the control assembly 300 protrudes from the surface of the housing 400 to allow the user to control the activation of the heating assembly 100.

[0031] like Figure 3 As shown, the heating assembly 100 includes a heating tube 110, which has a heating cavity for accommodating the aerosol-forming matrix 20. The top of the inner bracket 600 and the top of the middle frame decorative member 500 are kept clear of air at positions corresponding to the heating cavity, so that one end of the aerosol-forming matrix 20 can be inserted into the heating cavity, and the side of the aerosol-forming matrix 20 is heated by the heating tube 110.

[0032] Combine Figures 4 to 7As shown, the heating assembly 100 further includes a fixed tube 120, a mounting cover 130, and a mounting base 140. The diameter of the fixed tube 120 is larger than that of the heating tube 110, and the fixed tube 120 is sleeved on the heating tube 110, that is, the heating tube 110 is located within the fixed tube 120. The mounting cover 130 and the mounting base 140 are respectively located at opposite ends of the fixed tube 120, with the mounting cover 130 being closer to the suction end of the aerosol-forming substrate 20, while the mounting base 140 is further away from the suction end of the aerosol-forming substrate 20. Furthermore, the fixed tube 120, the mounting cover 130, and the mounting base 140 can all be made of PEEK (poly-ether-ether-ketone). Since PEEK has a heat deformation temperature of up to 230°C and a thermal conductivity of 0.29, it can simultaneously meet the requirements of high temperature resistance and low thermal conductivity. Of course, the fixing tube 120 , the mounting cover 130 and the mounting base 140 may also be made of materials such as PPSU (Polyphenylene sulfone resins), PPS (Polyphenylenesulfide), and chlorinated polyether, which are not specifically limited here.

[0033] The mounting cover 130 is connected to the first end 120A of the fixed tube, the mounting base 140 is connected to the second end 120B of the fixed tube, and the heating tube 110 is also connected to the mounting base 140. The fixed tube 120, the mounting cover 130 and the mounting base 140 together form a mounting cavity, and the heating tube 110 is located in the mounting cavity; the second end 120B of the fixed tube is connected to the mounting base 140 by a thread.

[0034] The embodiment of the present application adopts a threaded assembly method instead of a gap assembly method, so that the fixed tube 120 and the mounting base 140 are threadedly connected, which can effectively improve the situation where the assembly is too tight or too loose due to material tolerance fluctuations, resulting in improper assembly. As a result, when the heating tube 110 heats the aerosol-forming substrate 20, the smoke generated will not escape from the connection between the fixed tube 120 and the mounting base 140. Therefore, it can avoid the failure of the sealing effect between the fixed tube 120 and the mounting base 140, which may cause the smoke oil to leak out of the heating component and corrode the circuit board components.

[0035] Specifically, the mounting base 140 includes a bottom core 141, a bottom platform 142, and a bottom plate 143. The bottom core 141, bottom platform 142, and bottom plate 143 are integrally formed. Furthermore, the bottom core 141, bottom platform 142, and bottom plate 143 are arranged in sequence in a direction away from the mounting cover 130. The peripheral area of the bottom plate 143 is larger than that of the bottom platform 142, and the peripheral area of the bottom platform 142 is larger than that of the bottom core 141. It should be noted that the "peripheral area" refers to the area of the outermost contour of the structure.

[0036] The heating tube 110 is connected to the bottom core 141. The outer side of the base 142 is provided with an external thread 1421. The inner side of the second end 120B of the fixing tube is provided with an internal thread 121. The second end 120B of the fixing tube is threadedly connected to the base 142. When assembling the fixing tube 120, the fixing tube 120 is rotated and locked onto the external thread 1421 of the mounting base 140.

[0037] In some embodiments, the internal thread 121 and the external thread 1421 each have more than two turns to ensure stability and sealing between the fixing tube 120 and the mounting base 140 .

[0038] In some embodiments, after the fixing tube 120 is assembled with the mounting base 140 through threads, the bottom of the fixing tube 120 also abuts against the surface of the bottom plate 143 to further improve the stability of the fixing tube 120 and the sealing between the fixing tube 120 and the mounting base 140.

[0039] Combine Figure 5 and Figure 7 As shown, in some embodiments, the fixed tube 120 and the mounting base 140 are further sealed with a sealing ring. Specifically, the junction between the base 142 and the bottom plate 143 is concave to form an annular groove 144. The heating assembly 100 also includes an annular sealing ring 150, which is disposed within the annular groove 144 and engages with the annular groove 144 to secure the base 142. Furthermore, the annular sealing ring 150 is disposed around the central axis of the base 142. This embodiment achieves a dual sealing effect through the threaded engagement with the sealing ring, further improving the seal between the fixed tube 120 and the mounting base 140 and preventing e-liquid leakage and corrosion of circuit board components.

[0040] Among them, when the annular sealing ring 150 is assembled on the mounting base 140, the inner side of the annular sealing ring 150 abuts against the side wall of the annular groove 144, and the outer side of the annular sealing ring 150 abuts against the inner wall of the second end 120B of the fixed tube. At this time, even if the oil smoke penetrates between the internal thread 121 and the external thread 1421, it will be blocked by the annular sealing ring 150, so that it is difficult for oil leakage to occur.

[0041] like Figure 6 As shown, the heating assembly 100 further includes a heat exchange core 160, an insulation tube 190, and other structures. The heat exchange core 160 is disposed within the heating chamber and connected to the bottom core 141. The heat exchange core 160 is further provided with a plurality of airflow channels, which allow airflow to pass through and heat the passing airflow to achieve the effect of heating the bottom of the aerosol-forming substrate 20. The design of the heating tube 110 and the heat exchange core 160 in this embodiment of the present application allows for simultaneous heating of the sides and bottom of the aerosol-forming substrate 20, thereby improving the heating efficiency of the aerosol-forming substrate 20 and enhancing the user experience.

[0042] Moreover, by adding an insulating tube 190 between the heating tube 110 and the fixed tube 120, the insulating tube 190 is located inside the fixed tube 120 and is sleeved on the heating tube 110, so that the heat generated by the heating tube 110 during operation is concentrated on the aerosol-forming matrix 20, thereby improving the utilization rate of heat and further improving the heating efficiency of the aerosol-forming matrix 20.

[0043] like Figure 6 As shown, the heating assembly 100 further includes at least two heating elements 170. The heating elements 170 are made of a thermal resistor material and are disposed on the surface of the heating tube 110 to heat the heating tube 110. Each heating element 170 is connected to two electrodes 180. When the heating assembly 100 is in operation, the two electrodes 180 to which the heating elements 170 are connected are energized, causing current to flow through the heating elements 170, thereby generating heat. This in turn causes the heating tube 110 to generate heat, thereby heating the aerosol-forming substrate 20 located within the heating chamber.

[0044] In one embodiment, the heating assembly 100 includes three heating elements 170, which are evenly distributed across the entire outer surface of the heating tube 110. This design allows the heating tube 110 to generate heat evenly when all three heating elements 170 are energized simultaneously, thereby improving the uniformity of heating the aerosol-forming substrate 20.

[0045] On this basis, as a further embodiment, the three heating elements 170 can be independently controlled. According to different heating gears, different numbers of heating elements 170 can be selected to be energized to meet more user needs. For example, when the heat-without-combustion device 10 adopts the first gear mode, only one heating element 170 is energized, and only this heating element 170 heats the heating tube 110; when the heat-without-combustion device 10 adopts the second gear mode, both heating elements 170 are energized at the same time, and these two heating elements 170 heat the heating tube 110; when the heat-without-combustion device 10 adopts the third gear mode, all three heating elements 170 are energized at the same time, and these three heating elements 170 heat the heating tube 110.

[0046] Furthermore, as another further embodiment, two adjacent heating elements 170 share a single electrode 180. In this case, the two electrodes 180 can be used to control the operation of two or three heating elements 170. This reduces the number of electrodes 180 and wiring, increases design space, and avoids wiring problems. Similarly, based on this, it is also possible to select which two electrodes 180 to energize as needed to meet various usage requirements.

[0047] Of course, in the embodiment of the present application, the heating component 100 can also have only one, two or more than four heating elements 170, and can also select more types of heating gears. The specific design can be made according to actual conditions and will not be elaborated here.

[0048] In the heat-not-burn device 10, the power supply 200 and the heating component 100 are respectively located on both sides of the device, and most of the control components 300 are located at the bottom of the heating component 100, so that the various structures are reasonably distributed in the shell 400, thereby improving space utilization and reducing the overall volume of the heat-not-burn device 10.

[0049] like Figure 3 As shown, the control component 300 includes structures such as a circuit board 310, an oil cover 320, a sealing silicone sleeve 330, oil storage cotton 340, a silicone cover 350 and a switch 360. In the direction away from the heating component 100, the oil cover 320, the sealing silicone sleeve 330, the oil storage cotton 340 and the silicone cover 350 are distributed in sequence, wherein the oil cover 320 is matched with the bottom of the mounting base 140, and the silicone cover 350 is matched with the shell 400; in addition, the circuit board 310 is located between the oil cover 320 and the power supply 200, the length direction of the circuit board 310 is the same as the length direction of the power supply 200, and the circuit board 310 has a sensing device 311, and the switch 360 is located at one end of the power supply 200, at the top of the device.

[0050] Airway structures are provided at the bottom of the housing 400, as well as in the silicone cover 350, the sealing silicone sleeve 330, the oil cover 320, and the mounting base 140. When a user inhales from the heat-not-burn device 10, airflow passes through the bottom of the housing 400, sequentially passing through the sensor 311 on the circuit board 310, the silicone cover 350, the oil-storing cotton 340, the silicone cover 350, the oil cover 320, the mounting base 140, the airflow channel of the heat exchange core 160, and the heating tube 110, before entering the user's oral cavity from the suction end of the aerosol-forming matrix 20, thereby inhaling the aerosol.

[0051] The above content is a further explanation of the present application in conjunction with specific optional implementation methods, and the specific implementation of the present application cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, and all of them should be considered to fall within the scope of protection of the present application.
