Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomizing cup, an atomizing heating structure, and an atomizing device. Background Technology

[0002] An atomizing cup, as a container for holding an aerosol-forming matrix (ACM), is used to heat and atomize the ACM. In some atomizing devices that use hot airflow for heating, an airflow channel is formed between the side wall of the atomizing cup and the ACM inside. Air enters through this channel, and the airflow flowing into the atomizing cup is heated before flowing into the ACM for heating and atomization. In this case, the atomizing cup also serves to preheat the ACM. However, when using this type of atomizing cup to preheat the ACM, the heating and atomization effect is limited, and the ACM cannot obtain sufficient heat. Utility Model Content

When the heating element is an electromagnetic coil, the heating cup body is made of a magnetic material.

[0013] In one embodiment, a support portion is provided inside the bottom of the heating cup body. The support portion is used to support the aerosol forming matrix to form a bottom space between the aerosol forming matrix and the bottom of the heating cup body.

Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0026] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0027] When using aerosol forming matrix A, it is inserted into the atomizing cup 10. The atomizing cup 10 first heats the airflow flowing into it to obtain a hot airflow. This hot airflow then flows into the aerosol forming matrix A as the user inhales, thus heating and atomizing it to produce an aerosol that the user can inhale. During the initial heating phase, i.e., the preheating stage, the aerosol forming matrix A requires a large amount of heat; otherwise, the aerosol generation rate will be slow, requiring the user to wait a long time to inhale the first breath, affecting the user experience. Therefore, it is necessary to improve the heating and atomization effect of the atomizing cup 10 on the aerosol forming matrix A during the preheating stage so that the user can quickly inhale the aerosol.

[0028] Please see Figure 1 Figure 3 illustrates an embodiment of this application that provides an atomizing cup 10, comprising a heating cup body 11 and a heating element 12 fixedly connected. The cup opening 11a of the heating cup body 11 is used for inserting an aerosol forming matrix A into the heating cup body 11, and the internal space of the heating cup body 11 is used to accommodate the aerosol forming matrix A. An airflow channel is formed within the heating cup body 11, communicating with the outside environment and the end face (i.e., the end face near the bottom 11b) of the aerosol forming matrix A placed within the heating cup body 11. An interference fit 111 is provided on the side wall of the heating cup body 11, which is used to interference fit with the aerosol forming matrix A placed within the heating cup body 11. The heating element 12 is used to heat the heating cup body 11, thereby heating the atomized aerosol forming matrix A and the air flowing through the airflow channel.

[0029] Using the atomizing cup 10 in the above embodiments, when heating and atomizing the aerosol forming matrix A during the preheating stage, the heating element 12 heats the heating cup, and the heat on the heating cup heats the airflow flowing into the airflow channel to obtain a hot airflow. The hot airflow flows into the interior of the aerosol forming matrix A through the end face of the aerosol forming matrix A at the bottom 11b of the heating cup body 11, and moves along the axial direction of the aerosol forming matrix A to heat it. The heat from the heating cup body 11 can also be radially transferred to the aerosol forming matrix A through the interference surface 111 that is interference-fitted with the aerosol forming matrix A. The designed atomizing cup 10 can heat the aerosol forming matrix A from multiple angles, improving heat transfer efficiency, enabling the aerosol forming matrix A to quickly generate aerosols, and improving the heating and atomization effect of the aerosol forming matrix A during the preheating stage.

[0030] Please see Figure 1 The inner wall of the heating cup 11 is divided into a first region and a second region. An airflow channel is formed in the first region, and an interference surface 111 is provided in the second region. The interference surface 111 can ensure the contact area between the heating cup 11 and the side wall of the aerosol forming matrix A inside it, thereby ensuring the heat transfer efficiency and heat transfer, so as to improve the heating and atomization effect of the aerosol forming matrix A in the preheating stage.

[0031] Please see Figure 1 Specifically, multiple protrusions 112 are provided on the sidewall of the heating cup 11 in the first region, and air guide grooves 113 are formed between adjacent protrusions 112. It can be understood that multiple protrusions 112 can correspondingly form multiple air guide grooves 113, and the space within the air guide grooves 113 forms the aforementioned airflow channels, that is, multiple airflow channels are formed on the sidewall of the heating cup 11 in the first region. The length direction of the protrusions 112 can be distributed along the axial direction of the heating cup 11, or the length direction of the protrusions 112 can be inclined to the axial direction of the heating cup 11. The structural design of multiple protrusions 112 forming multiple strip-shaped air guide grooves 113 can increase the contact area between air and the groove wall of the air guide groove 113, thereby increasing the heat exchange efficiency of the heated airflow and improving the heating efficiency of the atomizing cup. In other embodiments, multiple radially protruding protrusions or pillar structures can also be provided on the sidewall of the heating cup 11 in the first region to form airflow channels between the sidewall of the aerosol forming matrix A and the sidewall of the heating cup 11.

[0032] In this embodiment, the sidewall thickness of the heating cup 11 in the second region is greater than that in the first region, so that the interference surface 111 on the sidewall of the heating cup 11 in the second region and the sidewall of the aerosol forming matrix A inside the heating cup 11 are interference-fitted, thus ensuring that the interference surface 111 and the sidewall of the aerosol forming matrix A are in close contact. In this case, the inner sidewall of the heating cup 11 in the second region can be used as the interference surface 111.

[0033] The interference surface 111 is mainly set to increase the heat provided to the aerosol forming matrix A during the preheating stage. The preheating stage takes less time than the later aerosol forming matrix A. Based on this, the area of ​​the first region is larger than the area of ​​the second region. For example, the area of ​​the first region accounts for 60% of the side wall area of ​​the heating cup 11, and the area of ​​the second region accounts for 40% of the side wall area of ​​the heating cup 11.

[0034] The protrusions 112 on the sidewall of the heating cup 11 in the first region can be in contact with or spaced apart from the sidewall of the aerosol forming matrix A. When the protrusions 112 in the first region are in contact with the sidewall of the aerosol forming matrix A, heat can be transferred to the aerosol forming matrix A. However, it should be noted that the outermost edge of the aerosol forming matrix A is wrapped with paper. If the contact area between the sidewall of the heating cup 11 and the sidewall of the aerosol forming matrix A, i.e., the wrapping paper, is too large, excessive heat will be transferred to the sidewall of the aerosol forming matrix A, which may scorch the wrapping paper and affect the user experience. Therefore, more preferably, in this embodiment, the protrusions 112 and the sidewall of the aerosol forming matrix A are spaced apart, that is, the wall thickness of the heating cup 11 where the protrusions 112 are located is less than the wall thickness of the heating cup 11 where the interference surface 111 is located. Specifically, for example, the wall thickness of the heating cup 11 with the protrusion 112 is 0.5 mm smaller than the wall thickness of the heating cup 11 with the interference surface 111, or the difference in thickness between the two is no more than 0.5 mm.

[0035] In some embodiments, the inner wall of the heating cup 11 can be divided into multiple first regions and multiple second regions, with the first regions and second regions distributed alternately. For example, the inner wall of the heating cup 11 is divided into two first regions and two second regions. In this case, with the first regions and second regions distributed alternately, the heating cup 11 can heat the atomized aerosol to form matrix A more uniformly and symmetrically.

[0036] More preferably, in this embodiment, the heating element 12 is fixed to the outside of the bottom 11b of the heating cup body 11. Fixing the heating element 12 to the outside of the bottom 11b of the heating cup body 11, that is, placing the heat source relatively far away from the aerosol forming matrix A, allows control over the heat transferred from the heating cup body 11 to the sidewall of the aerosol forming matrix A. Combined with the interference surface 111 provided on a local sidewall of the heating cup body 11, the heat transferred from the heating cup body 11 to the sidewall of the aerosol forming matrix A can be further controlled, preventing the outermost wrapping paper of the aerosol forming matrix A from being scorched. Since the sidewall of the heating cup body 11 with the interference surface 111 is relatively thicker, the heat conduction efficiency of the heating cup body 11 at that location is also higher, facilitating radial heating of the aerosol forming matrix A.

[0037] The heating element 12 is either a resistance heating element or an electromagnetic coil 12. When the heating element 12 is a resistance heating element, the heating cup body 11 is made of a thermally conductive material. In this case, the heating element 12 is, for example, a sheet-like resistance heating circuit. The two ends of the heating element 12 are respectively provided with connecting electrodes 121. Either of the two connecting electrodes 121 is electrically connected to the positive terminal of the battery core 90, and the other of the two connecting electrodes 121 is electrically connected to the negative terminal of the battery core 90. The battery core 90 provides electrical energy to the heating element 12, which generates heat and conducts the heat to the heating cup body 11. The heating cup body 11 then uses the obtained heat to reheat and atomize the aerosol inside to form matrix A. When the heating element 12 is an electromagnetic coil, the heating cup body 11 is made of magnetic material. For example, if the heating element 12 is an electromagnetic coil, the heating cup body 11 is made of iron, iron-silicon alloy, graphite, stainless steel, etc. The electromagnetic coil is fixed on the bottom 11b of the cup in a spiral shape. When an alternating current is passed through the electromagnetic coil, an alternating magnetic field is generated. The heating cup body 11 with a certain magnetic permeability will generate an alternating current (i.e., eddy current), which will generate heat energy to heat the atomized aerosol to form matrix A.

[0038] Specifically, in this embodiment, the heating element 12 is a resistance heating element, which is fixed to the bottom 11b of the heating cup body 11 by printing and sintering.

[0039] More preferably, the bottom 11b of the heating cup body 11 is a conical bottom 114. The radial dimension of the conical bottom 114 increases continuously from the side near the cup opening 11a to the side away from the cup opening 11a, so that the end face of the bottom 11b is larger than the end face at the cup opening 11a, thereby providing more installation area for the heating element 12 and improving the heating atomization effect.

[0040] Specifically, the bottom 11b of the heating cup body 11 is provided with a support portion, which supports the aerosol forming matrix A to form a bottom space between the aerosol forming matrix A and the bottom 11b of the heating cup body 11. The bottom space is connected to the airflow channel. The support portion is, for example, divided into a first support portion 115 and a second support portion 116. The first support portion 115 is located in the bottom 11b corresponding to the first region, and the second support portion 116 is located in the bottom 11b corresponding to the second region. The structures of the first support portion 115 and the second support portion 116 can be the same or different, and the number of first support portions 115 and the number of second support portions 116 can be the same or different. More specifically, for example, multiple first support portions 115 are configured, with each first support portion 115 corresponding to a protrusion 112. The first support portion 115 is located at the end of the protrusion 112 near the bottom of the cup 11b, and the first support portion 115 and the protrusion 112 form an approximately L-shaped support strip as an integral structure. A single second support portion 116 is configured, which is an arc-shaped support strip distributed circumferentially along the heating cup body 11. In other embodiments, multiple support portions can also be provided in the middle of the bottom of the cup 11b. For example, the support portions can be blocks, columns, ribs, etc., as long as the support portions can support the aerosol forming matrix A and form a bottom space between the aerosol forming matrix A and the bottom of the cup 11b. This application does not limit the specific form of the support portions.

[0041] The atomizing cup 10 in the above embodiments of this application is an atomizing cup 10 that realizes local sidewall hot airflow. The heating element 12 is set at the bottom of the heating cup body 11. The heating element 12 transfers heat to the heating cup body 11. Through the airflow channel in the heating cup body 11, heat is exchanged with the air to generate hot airflow, which axially heats the aerosol forming matrix A. In addition, the interference surface 111 in the heating cup body 11 is also interference-fitted with the aerosol forming matrix A to radially heat the aerosol forming matrix A, thereby improving the heat exchange efficiency and improving the heating and atomization effect of the aerosol forming matrix A in the preheating stage, so as to generate aerosol for the user to inhale more quickly.

[0042] Please see Figures 4-5In another embodiment of this application, an atomizing heating structure is provided, including a sleeve 20 and an atomizing cup 10, wherein the atomizing cup 10 is the same as that in the above embodiment. The outer side of the cup opening 11a of the heating cup body 11 is provided with a cup opening protrusion 117, and a stop surface 224 is formed inside the sleeve 20. The heating cup body 11 is suspended inside the sleeve 20 through the cooperation of the cup opening protrusion 117 and the stop surface 224. Through the cooperation of the cup opening protrusion 117 and the stop surface 224, the atomizing cup 10 can be quickly suspended inside the sleeve 20. Furthermore, by suspending the atomizing cup 10, that is, suspending the heating element 12 on the atomizing cup 10 inside the sleeve 20, the problem of melting caused by contact between the heating element 12 and other components can be avoided. The sleeve 20 in the atomizing heating structure can enclose the atomizing cup 10, that is, it can form a heat-insulating space, preventing the heat generated by the atomizing cup 10 from diffusing to other unwanted areas, thereby improving the thermal efficiency of the atomizing cup 10.

[0043] Please see Figures 4-5 The atomizing heating structure also includes a fixing base 30. The sleeve 20 includes an outer tube 21 and an inner tube 22 connected together. The inner tube 22 is fitted inside the outer tube 21, and the outer diameter of the inner tube 22 is smaller than the inner diameter of the outer tube 21. A stop surface 224 is formed on the inner tube 22. The fixing base 30 abuts against the cup mouth protrusion 117. A through channel is formed within the fixing base 30 for inserting the aerosol forming matrix A into the heating cup body 11.

[0044] Specifically, the inner tube 22 includes a first tube body 221, a second tube body 222, and a third tube body 223 connected axially in sequence. The first tube body 221 is located on the side closer to the fixing seat 30, and the third tube body 223 is located on the side farther from the fixing seat 30. The two ends of the first tube body 221 are connected to the inner wall of the outer tube 21 and the end face of the second tube body 222, respectively. The first tube body 221 is, for example, a tapered tube, and the tapered surface of the tapered tube facilitates the entry of the fixing seat 30 and the abutment of the cup mouth protrusion 117. The inner diameter of the second tube body 222 is larger than the inner diameter of the third tube body 223, so as to form a stop surface 224 at the connection between the second tube body 222 and the third tube body 223. The outer diameter of the third tube body 223 is smaller than the inner diameter of the outer tube 21, so as to form a heat-insulating space between the outer tube 21 and the atomizing cup 10.

[0045] The atomizing heating structure also includes a matrix fastening ring 40 and a base 50. One end of the fixing base 30 abuts against the cup mouth protrusion 117, and the other end abuts against the end face of the outer tube 21. The fixing base 30 has a guide surface 321 inside. The matrix fastening ring 40 is sleeved inside the fixing base 30 at the end away from the heating cup body 11. The inner wall of the matrix fastening ring 40 has a plurality of circumferentially spaced elastic clamping parts 41, which are used to tightly fit with the side wall of the aerosol forming matrix A. The base 50 is fixed to the end of the outer tube 21 away from the fixing base 30.

[0046] Specifically, the mounting base 30 includes, along its axial direction, a first mounting tube 31, a second mounting tube 32, and a third mounting tube 33 connected in sequence. The first mounting tube 31 is located on the side closer to the atomizing cup 10, and the third mounting tube 33 is located on the side farther from the atomizing cup 10. A cup opening protrusion 117, for example, is a raised ring on the outer wall of the cup opening 11a, which abuts against the first mounting tube 31. The second mounting tube 32 has a guide surface 321, for example, a conical annular surface, which facilitates the aerosol forming matrix A to pass through the mounting base 30 and be inserted into the atomizing cup 10. A matrix fastening ring 40 is fitted inside the third tube body 223. The matrix fastening ring 40 is made entirely of an elastic material, such as silicone or rubber. The outer diameter of the matrix fastening ring 40 can be slightly larger than the inner diameter of the third mounting tube 33 to ensure a tight fit between the matrix fastening ring 40 and the third mounting tube 33. The inner wall of the matrix fastening ring 40 is provided with elastic clamping parts 41. On the one hand, it can fit tightly with the side wall of the aerosol forming matrix A. On the other hand, it can form an air inlet by enclosing the matrix fastening ring 40, the side wall of the aerosol forming matrix A, and two adjacent elastic clamping parts 41. Multiple elastic clamping parts 41 form multiple air inlets. For example, multiple elastic clamping parts 41 are equally spaced around the inner wall of the matrix fastening ring 40. The air inlets formed on the matrix fastening ring 40 are axial air inlets. This can shorten the flow path of the airflow in the atomizing cup 10, ensure the suction effect of the aerosol forming matrix A, and facilitate the cleaning of the air inlets. If the airflow path is too long, for example, when air is introduced through the side wall, the aerosol generated after heating and atomization will diffuse in the atomizing cup 10. The diffusion space of the aerosol is large, and after diffusion, condensate will form. If it accumulates in the atomizing cup 10 for a long time, it will produce an odor and may even block the air inlets. The base 50 and the fixing seat 30 are respectively fixed to both ends of the outer tube 21 to facilitate the formation of a relatively sealed heat-insulating space. Even better, a reflective film 60 can be fixed on the inner wall of the outer tube 21. The reflective film 60 can reflect the heat radiation generated by the heating element 12 to avoid excessive heat being transferred outward.

[0047] Please see Figure 4 Figure 5 shows that the atomizing heating structure also includes an end cap 70 with an opening to allow the aerosol forming matrix A to enter the atomizing cup 10. The outer wall of the end cap 70 has multiple radially protruding snap-fit ​​portions 71. Multiple mating interfaces 34 are provided on the end face of the third fixing tube 33 in the fixing seat 30 away from the first fixing tube 31. The snap-fit ​​portions 71 and mating interfaces 34 can be connected to the end cap 70 and the fixing seat 30 by means of tight fitting, adhesive bonding, welding, etc. Through the end cap 70, the fixing seat 30 and the matrix fastening ring 40 are clamped and fixed inside the outer tube 21, forming a relatively complete atomizing heating structure, which also facilitates the later assembly of the atomizing heating structure in the atomizing device.

[0048] Please see Figure 6In another embodiment of this application, an atomizing device is provided, including a housing 80, a battery 90, a circuit board 100, and an atomizing heating structure, wherein the atomizing heating structure is the same as that in the above embodiment. The battery 90, circuit board 100, and atomizing heating structure are all fixed within the housing 80. The heating element 12 in the battery 90 and the atomizing heating structure are electrically connected to the circuit board 100. The battery 90 provides power to the heating element 12, and the circuit board 100 controls the operating state of the heating element 12. Insertion ports 81 are provided at positions corresponding to the end caps 70 in the atomizing heating structure within the housing 80 to facilitate the entry of the aerosol forming matrix A into the atomizing cup 10.

[0049] Since both the atomizing heating structure and the atomizing device include the atomizing cup 10 in the above embodiments, they also have the advantages of the atomizing cup 10 in the above embodiments, so they will not be described again here.

[0050] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
