DETAILED DESCRIPTION
[0028] The application will be described in further detail below with specific reference to the drawings. Like elements are referred to with like reference numerals throughout the various figures and embodiments. In the following description, numerous specific details are described to provide a thorough understanding of the application. However, it will be apparent to those skilled in the art that the application can be practiced without many of these details. In some instances, well-known structures have not been described in detail in order to avoid obscuring the application. Also, the description and drawings are to be considered illustrative only.
[0029] In addition, the features, operations, or steps described in the specification can be combined in any suitable manner without departing from the scope of the application. Furthermore, those skilled in the art will recognize that steps or acts from different embodiments can be substituted for one another, and that suitable results can be achieved by combining steps or acts from different embodiments during different stages of a process. Therefore, the description and drawings should not be construed as limiting the application, but rather merely as illustrating different features or aspects of the application.
[0030] The serial numbers of components in the specification, such as "first", "second", etc., are used only to distinguish the described objects, and do not have any sequential or technical meaning. The application refers to "connection" or "coupling", unless otherwise specified, which includes direct and indirect connection (coupling).
[0031] The aerosol-forming substrate is usually provided with a wrapping paper on the outer layer, which is fixed by adhesion or dispensing. During the preheating stage of the aerosol-forming substrate, the heating cup in the atomizer will heat and roast the wrapping paper on the outer side of the aerosol-forming substrate. After the wrapping paper is heated and roasted, the gum material on it will produce a lot of odor, which exists in the heating cup of the atomizer. Because the space of the side wall of the heating cup is relatively closed, if the content of odor in the heating cup is not reduced in time, it will make the odor heavier when the aerosol-forming substrate is smoked, affecting the user's smoking experience.
[0032] Please refer to Figures 1-5 In an embodiment of the application, an atomizer is provided for heating and atomizing an aerosol-forming substrate A and generating aerosol for a user to smoke. The atomizer comprises a heating cup 10, a heating element 20, an auxiliary assembly structure 30, and an airway valve 40.
[0033] The heating cup 10 is used to be inserted with the aerosol forming substrate A. The inner wall of the heating cup 10 is provided with the airflow channel 12, which respectively communicates with the outside and the bottom of the heating cup 10. The heating element 20 is fixed to the heating cup 10. The auxiliary assembly structure 30 is connected to the cup opening of the heating cup 10. The auxiliary assembly structure 30 is formed with the insertion channel, which is used for the aerosol forming substrate A to pass through to be inserted into the heating cup 10. The cup opening of the heating cup 10 and / or the insertion channel is provided with the airway valve 40, which is used to release the miscellaneous gas generated after the aerosol forming substrate A is heated. The airway valve 40 is also used to prevent the miscellaneous gas from the outside from flowing back to the heating cup 10. That is, the designed airway valve 40 is similar to the structure of the one-way valve, which realizes the one-way flow of the miscellaneous gas in the heating cup 10 to the outside. In this way, the content of the miscellaneous gas in the heating cup 10 can be continuously reduced, thereby reducing the influence of the miscellaneous gas on the suction taste when the aerosol forming substrate A is used to suck the aerosol, and improving the user experience.
[0034] Specifically, the heating element 20 is fixed to the bottom of the heating cup 10. The heating element 20 is used to assist the heating cup 10 to heat. The heated heating cup 10 can heat the aerosol forming substrate A.
[0035] The heating element 20 is an electric resistance heating element or an electromagnetic heating element. When the heating element 20 is an electric resistance heating element, the heating element 20 and the heating cup 10 are both high thermal conductivity materials. For example, the heating element 20 is an aluminum alloy, copper, aluminum nitride, or other materials with a thermal conductivity > 15 W / (K*m). The heating cup 10 is aluminum nitride, silicon carbide, alumina, or other materials with a thermal conductivity > 15 W / (K*m). At this time, the heating element 20 is a sheet-shaped electric resistance heating line. After the heating element 20 is electrified and heated, the heat is transferred to the heating cup 10. The heating cup 10 heats the aerosol forming substrate A in it by obtaining the heat. When the heating element 20 is an electromagnetic heating element, the heating cup 10 is a magnetic material. For example, the heating element 20 is an electromagnetic coil, and the heating cup 10 is iron, iron-silicon alloy, graphite, stainless steel, or other materials. The electromagnetic coil is electrified with alternating current, thereby generating an alternating magnetic field. The corresponding heating cup 10 with a certain magnetic permeability generates an alternating current, thereby generating heat energy to heat the aerosol forming substrate A in it.
[0036] Please refer to Figures 1-2The auxiliary assembly structure 30 comprises an assembly tube 31, a clamping ring 32 and a top cover 33. One end of the assembly tube 31 is connected with the cup opening of the heating cup 10, the other end of the assembly tube 31 is connected with the top cover 33, and the clamping ring 32 is fixed in the end of the assembly tube 31 away from the heating cup 10. The inner wall of the clamping ring 32 is provided with a plurality of clamping portions 321 distributed at intervals, which are used to abut against the outer wall of the aerosol-forming substrate A. The clamping ring 32 is mainly arranged to ensure the stability of the aerosol-forming substrate A installed on the atomizer. For example, the clamping ring 32 is a silica gel ring, and the clamping portions 321 are silica gel protrusions, protruding plates or protruding balls distributed at equal intervals on the inner wall of the silica gel ring. The clamping portions 321 can form a gap between the inner wall of the clamping ring 32 and the outer wall of the aerosol-forming substrate A, so that external air can enter the airflow passage 12 in the heating cup 10. Among them, in order to facilitate assembly, the clamping ring 32 can be sleeved and fixed in the assembly tube 31.
[0037] Specifically, at least one air passage valve 40 is arranged in the insertion channel. The auxiliary assembly structure 30 comprises an assembly tube 31, a clamping ring 32 and a top cover 33, and correspondingly, the air passage valve 40 can be arranged on at least one of the assembly tube 31, the clamping ring 32 and the top cover 33, for example, one air passage valve 40 is arranged on the inner wall of the assembly tube 31 and the inner wall of the top cover 33 respectively.
[0038] More specifically, in the embodiment of the present application, the air passage valve 40 is arranged on the inner wall of the assembly tube 31. On the one hand, the air passage valve 40 is relatively close to the heating cup 10, which is convenient for the flow of the mixed gas generated in the heating cup 10 to flow out, and on the other hand, it is convenient to arrange the air passage valve 40.
[0039] Please refer to Figure 3 The assembly tube 31 comprises a first tube body 311 and a second tube body 312 connected with each other. The first tube body 311 is located close to the heating cup 10, and the second tube body 312 is located away from the heating cup 10. The air passage valve 40 is arranged on the inner wall of the first tube body 311, and the clamping ring 32 is fixed in the second tube body 312. At this time, the air passage valve 40 is relatively close to the heating cup 10. The path of the mixed gas in the heating cup 10 flowing out of the heating cup 10 can be shortened, thereby facilitating the flow of the mixed gas in the heating cup 10 out of the heating cup 10.
[0040] Please refer to Figure 3More preferably, the assembly tube 31 further comprises a third tube body 313, two ends of the third tube body 313 are connected with the first tube body 311 and the second tube body 312 respectively, the radial dimension of the third tube body 313 is continuously increased from the first tube body 311 to the second tube body 312, that is, the third tube body 313 is a tapered tube body, the tapered inner wall of the third tube body 313 can guide the aerosol-forming substrate A, so that the aerosol-forming substrate A can be quickly and accurately inserted into the heating cup 10. Among them, in order to facilitate processing, the first tube body 311, the second tube body 312 and the third tube body 313 are an integral structure.
[0041] The more the number of airway valves 40 is, the more the relative unidirectional flow of the impure gas in the heating cup 10 is guaranteed, that is, the more the number of airway valves 40 is, the easier the impure gas in the heating cup 10 flows out, but the more difficult the impure gas from the outside flows into the heating cup 10. Therefore, along the axial direction of the heating cup 10, the airway valves 40 are arranged in multiple. Specifically, in the embodiment of the present application, a plurality of airway valves 40 are arranged axially on the inner wall of the first tube body 311 in the assembly tube 31, for example, two airway valves 40 are arranged axially and spaced apart on the inner wall of the first tube body 311.
[0042] In some embodiments, the airway valve 40 is an arc-shaped plate or a ring-shaped plate, for example, as shown in Figure 1 and Figure 3 As shown, the airway valve 40 is provided with a guide inclined surface 41 towards the bottom end of the heating cup 10, and a gap channel is formed between the airway valve 40 and the side wall of the aerosol-forming substrate A inserted into the heating cup 10.
[0043] The impure gas generated in the heating cup 10 flows out of the heating cup 10 through the gap channel through the guide inclined surface 41. Under the structure of the guide inclined surface 41, the radial space of the guide inclined surface 41 becomes smaller and smaller from the side close to the bottom of the heating cup 10 to the side away from the bottom of the heating cup 10, so that the impure gas in the heating cup 10 is easy to go out and difficult to come in. And because the concentration of the impure gas in the heating cup 10 is relatively larger than that of the impure gas outside, the impure gas flowing out of the heating cup 10 is obviously more than the impure gas flowing into the heating cup 10 from the outside, therefore, through the one-way valve, the effect of approximately unidirectional flow can be achieved, which can continuously reduce the content of the impure gas in the heating cup 10, guarantee the taste when the user smokes the aerosol-forming substrate A through the atomizer, and further improve the user experience.
[0044] When the air passage valve 40 provided with the guide slope 41 is an arc-shaped plate, a plurality of arc-shaped plates are circumferentially arranged at the same axial position, and gaps (not shown) are formed between circumferentially adjacent arc-shaped plates. The gaps are distributed staggered at different axial positions. For example, four arc-shaped plates are circumferentially arranged at equal intervals on the inner wall of the first pipe body 311 at the same axial position, and the four arc-shaped plates form four gaps. The gaps at different axial positions are distributed staggered, which can increase the difficulty of the external miscellaneous gas flowing back into the heating cup 10, and more easily reduce the content of miscellaneous gas in the heating cup 10. Because the concentration of miscellaneous gas in the heating cup 10 is relatively high compared to the concentration of miscellaneous gas in the external environment, even if the gaps at different axial positions are distributed staggered, the effect on the miscellaneous gas flowing from the heating cup 10 to the external environment will be relatively small.
[0045] In other embodiments, the air passage valve 40 is an arc-shaped plate or a ring-shaped plate, for example, as shown in FIG. 6, a plurality of circumferentially spaced guide holes 42 are formed on the air passage valve 40, and the hole diameter of the guide hole 42 gradually decreases from the side close to the heating cup 10 to the side away from the heating cup 10. Figure 4
[0046] Through the guide hole 42, the miscellaneous gas flowing out of the heating cup 10 is provided with a relatively large caliber, which facilitates the flow of miscellaneous gas out of the heating cup 10. Moreover, the hole diameter of the guide hole 42 gradually decreases from the side close to the heating cup 10 to the side away from the heating cup 10, so that the miscellaneous gas passing through the guide hole 42 is also gathered and accelerated, facilitating the rapid flow of miscellaneous gas out of the heating cup 10. Conversely, when the external miscellaneous gas flows into the heating cup 10, on the one hand, the hole diameter of the corresponding guide hole 42 of the heating cup 10 is small, and on the other hand, the guide hole 42 has a diffusion effect when the miscellaneous gas flows into the heating cup 10, which easily reduces the power of the miscellaneous gas flowing into the heating cup 10, thereby increasing the difficulty of the miscellaneous gas flowing into the heating cup 10.
[0047] More preferably, the guide holes 42 on the axially adjacent air passage valves 40 are distributed staggered to further increase the difficulty of the external miscellaneous gas flowing back into the heating cup 10.
[0048] When the air passage valve 40 provided with the guide hole 42 is an arc-shaped plate, a plurality of arc-shaped plates are circumferentially arranged at the same axial position, and gaps are formed between circumferentially adjacent arc-shaped plates. The gaps are distributed staggered at different axial positions. For example, three arc-shaped plates are circumferentially arranged at equal intervals on the inner wall of the first pipe body 311 at the same axial position, and the three arc-shaped plates form three gaps. At this time, the gaps at different axial positions are distributed staggered, which can further increase the difficulty of the external miscellaneous gas flowing back into the heating cup 10, so as to sufficiently reduce the content of miscellaneous gas in the heating cup 10 and ensure the suction effect when the user sucks the aerosol-forming substrate A by the atomizer.
[0049] For easy processing and assembly, the air passage valve 40 and the first pipe body 311 in the assembly pipe 31 are an integral structure.
[0050] Referring to Figures 2-3 Specifically, the top cover 33 is a ring-shaped top cover 33, the middle passage of the top cover 33 is used for passing the aerosol-forming substrate A, and the top cover 33 and the assembly pipe 31 are connected in a convex-concave matching mode, for example, a plurality of spaced-apart clamping blocks 331 are circumferentially arranged on the outer side wall of the top cover 33, the clamping blocks 331 are radially outwardly convex, and a plurality of spaced-apart clamping grooves 3121 are circumferentially arranged on the end of the second pipe body 312 of the assembly pipe 31, and the clamping blocks 331 and the clamping grooves 3121 are connected in a convex-concave matching mode, so as to realize the detachable connection between the top cover 33 and the assembly pipe 31.
[0051] Referring to Figure 1 The heating cup 10 is axially divided into a first heating area 10a and a second heating area 10b, the first heating area 10a is located close to the cup opening side of the heating cup 10, and the second heating area 10b is located close to the cup bottom side of the heating cup 10. A plurality of first support portions 11 are arranged on the inner wall of the heating cup 10 in the first heating area 10a, and the plurality of first support portions 11 are used for forming an airflow passage 12. A second support portion 13 is arranged in the cup bottom of the heating cup 10, and the second support portion 13 is used for contacting the end face of the aerosol-forming substrate A, so as to separate a space from the airflow passage 12 between the end face of the aerosol-forming substrate A and the cup bottom of the heating cup 10.
[0052] Specifically, for example, the first support portion 11 is a support strip, the length direction of the support strip is parallel or inclined to the axial direction of the heating cup 10, and the circumferentially adjacent support strips form a slot-shaped airflow passage 12, and the second support portion 13 can be one or more, and the second support portion 13 can be strip-shaped, block-shaped, ring-shaped, etc., as long as the second support portion 13 can support the end face of the aerosol-forming substrate A.
[0053] More preferably, the face of the support strip towards the axis of the heating cup 10 is an arc-shaped curved surface, the arc-shaped curved surface and the outer wall of the aerosol-forming substrate A have relatively small contact area, and the inner wall of the heating cup 10 in the second heating area 10b and the outer wall of the aerosol-forming substrate A are not in contact, so that the heat of the inner wall of the heating cup 10 transferred to the wrapping paper on the outer wall of the aerosol-forming substrate A can be reduced, and the generation amount of the miscellaneous gas can be reduced.
[0054] Referring to Figures 1-2The atomizer further comprises a sleeve 50, a base 60 and a reflective film 70, the heating cup 10 is hung in the sleeve 50, the end of the assembly pipe 31 and the cup mouth of the heating cup 10 abut, and the assembly pipe 31 and one end of the sleeve 50 are sleeved, the other end of the sleeve 50 and the base 60 are sleeved, and the inner wall of the sleeve 50 is fixed with the reflective film 70. A relatively closed space is formed by the sleeve 50 and the assembly pipe 31 and the base 60 at both ends of the sleeve 50, and the reflective film 70 on the inner wall of the sleeve 50 can effectively prevent the heat in the sleeve 50 and the heating cup 10 from spreading outward, thereby improving the thermal efficiency of the atomizer and reducing the power consumption of the atomizer.
[0055] Please refer to Figures 1-5 Specifically, the cup mouth of the heating cup 10 is provided with a radially outward convex ring 14, the inside of the sleeve 50 is provided with a connecting ring 51 and a blocking ring 52, the two ends of the connecting ring 51 are integrally connected with the inner wall of the sleeve 50 and the outer wall of the blocking ring 52, respectively, the heating cup 10 is hung in the inside of the sleeve 50 by abutting the convex ring 14 and the blocking ring 52, the connecting ring 51 is a conical ring, which facilitates the first pipe body 311 of the assembly pipe 31 to abut the sleeve 50 and the convex ring 14 of the heating cup 10, and the second pipe body 312 of the assembly pipe 31 abuts the end face of the sleeve 50.
[0056] Please refer to Figure 1 and Figure 6 When the atomizer is used to suck the aerosol-forming substrate A, the external airflow enters the inner wall of the heating cup 10 through the gap between the clamping ring 32 and the side wall of the aerosol-forming substrate A and the gap channel at the airway valve 40, the external airflow at the space in the inner wall of the heating cup 10 is changed into hot airflow through heat exchange, the hot airflow flows to the bottom of the heating cup 10, flows into the aerosol-forming substrate A through the end face of the aerosol-forming substrate A, and performs heating action, so that the aerosol-forming substrate A can quickly generate aerosol for the user to smoke.
[0057] When the aerosol-forming substrate A is heated, the generated miscellaneous gas in the heating cup 10 is more easily released to the outside through the airway valve 40 in the inner wall of the assembly pipe 31 and is more difficult to flow back to the heating cup 10, thereby effectively reducing the miscellaneous gas in the heating cup 10 and improving the use experience of the atomizer.
[0058] Please refer to Figure 6 In another embodiment of the present application, a heating and non-combustion atomizing device is provided, which comprises an atomizer, a shell 80 and a power supply assembly 90, the atomizer and the power supply assembly 90 are fixed in the shell 80, and the atomizer is the atomizer in the above-mentioned embodiments.
[0059] The power supply assembly 90 comprises an electric core 91 and a circuit board 92, the heating element 20 and the electric core 91 are electrically connected with the circuit board 92, the electric core 91 is used for providing electric energy for the heating element 20, and the circuit board 92 is used for controlling the working state of the heating element 20, for example, the circuit board 92 controls whether to provide electric energy for the heating element 20, the size of the provided power and the like. The top of the shell 80 is provided with a plug-in port 81, the plug-in port 81 and the auxiliary assembly structure 30 and the heating cup 10 are coaxially arranged, and the aerosol forming substrate A enters the heating cup 10 through the plug-in channel in the plug-in port 81 and the auxiliary assembly structure 30. Wherein, the top cover 33 and the shell 80 can adopt high-temperature-resistant and low-thermal-conductivity materials, such as peek, ppsu and the like.
[0060] The above application of specific examples to illustrate the present application, is used to help understand the present application, and does not limit the present application. For the skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformation or replacement can be made.
