Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically, to an air intake structure and a heating non-combustible device. Background Technology

[0002] A heated non-combustible device is an appliance that heats and bakes aerosol-generating products to produce aerosols. The heated non-combustible device requires an air inlet channel to allow external airflow to enter and mix with the aerosol generated within the device for inhalation by the user.

[0003] Based on the location of the air inlet, air intake methods can be divided into three types: bottom air intake (air inlet is far from the nozzle), top air intake (air inlet and nozzle are on the same side), and side air intake (air inlet is on the side of the device). For top air intake, the direction of airflow entering the heated non-combustible device is opposite to the direction of airflow exiting the device (where it mixes with the generated aerosol before exiting). Therefore, the airflow direction needs to be adjusted within the heated non-combustible device. However, in existing top air intake structures, the process of changing the airflow direction is not smooth, affecting suction. Utility Model Content

[0004] The main objective of this application is to provide an air intake structure and a heating non-combustion device to solve the problem of poor airflow during the change of airflow direction in the existing top air intake structure.

[0011] Furthermore, the first support structure includes a plurality of first support ribs, which are respectively connected to the side of the sealing structure near the containment chamber.

[0012] Furthermore, the first support rib includes a first part and a second part, wherein the second part is connected between the first part and the sealing structure;

[0016] The support member is also configured to form a second support structure, which is connected to the sealing structure and extends into the second support tube located on the periphery of the first support structure. The second support structure is connected to the first support tube corresponding to the second opening end and has a second notch, which connects the air intake channel and the containment chamber.

[0017] Furthermore, the second support structure includes three second support ribs, each of which corresponds to one of the first support ribs and is located outside the corresponding first support rib, wherein the second notch is formed between adjacent second support ribs.

[0018] Furthermore, the main body includes a heating element, which is held between the second support structure and the first support tube, and the heating element is connected to the first support tube to form the receiving chamber.

[0019] Furthermore, the main body includes a heat dissipation component, which is disposed on the periphery of the heat-generating component and abuts against the second support structure and the first support tube.

[0020] Furthermore, the heat dissipation component includes a heat dissipation pipe and a heat dissipation fin. The heat dissipation pipe is sleeved around the periphery of the heat-generating component and abuts against the second support structure and the first support pipe. The heat dissipation fin is connected to the outside of the heat dissipation pipe and extends into the air intake channel.

[0021] Furthermore, the first support tube has an air inlet near the first opening end, and the air inlet is connected to the air inlet end.

[0040] Please see Figure 1-3 As shown, this application provides an air intake structure 100, which includes a main body and a support member 20. The main body is configured to form a receiving chamber 30 and an air intake channel 40. The air intake channel 40 is located outside the receiving chamber 30.

[0041] The receiving chamber 30 has a first opening end and a second opening end. An aerosol generating article 2000 enters the receiving chamber 30 through the first opening end, such that the matrix segment of the aerosol generating article 2000 is inserted into the receiving chamber 30 and heated and baked within the receiving chamber 30 to generate an aerosol. External airflow enters the receiving chamber 30 through the air inlet channel 40, and then enters the aerosol generating article 2000 from within the receiving chamber 30, mixing with the generated aerosol before flowing out from the nozzle segment 2100 of the aerosol generating article 2000.

[0042] Furthermore, the air intake channel 40 has opposing air intake ends and air outlet ends. The second opening end is located between the air intake end and the air outlet end, and is close to the air outlet end.

[0043] The support member 20 is configured to form a sealing structure 21, which is sealed to the air outlet end. The sealing structure 21 is spaced apart from the second opening end so that the air outlet end of the air inlet channel 40 is connected to the second opening end of the receiving chamber 30, thereby forming an intervening space for the airflow in the air inlet channel 40 to enter the receiving chamber 30.

[0044] Further, please refer to Figure 3As shown, the direction in which the external airflow enters the air intake channel 40 is the same as the direction in which the aerosol generating article 2000 is inserted into the containment chamber 30, and is a first direction. The direction of airflow movement within the containment chamber 30, and the direction in which it enters the aerosol generating article 2000 from the matrix section 2300 within the containment chamber 30, are the same, and are a second direction. The second direction is opposite to the first direction, so that the airflow within the air intake channel 40 needs to turn around within the main body to change its direction of movement as it flows out from the outlet end and enters the containment chamber 30 from the second opening end.

[0045] Therefore, in this embodiment, the air outlet is sealed by the sealing structure 21, and the second opening is located between the air inlet and the air outlet, with the second opening close to the air outlet and spaced a certain distance from the sealing structure 21 to form an interval space for the airflow to turn around. This allows the airflow in the air inlet channel 40 to turn around smoothly in the interval space and enter the receiving chamber 30, thereby reducing the suction resistance during suction and improving the user experience.

[0046] Furthermore, in the first embodiment, the air intake channel 40 is separated from the containment chamber 30 so that the air intake end and the first opening end are located on the same side of the main body, and the air intake end is directly connected to the outside of the main body, and the external airflow directly enters the air intake channel 40 from the air intake end.

[0047] In the second embodiment, the air inlet is connected to the containment chamber 30 and is close to the first opening, so that the external airflow first enters the containment chamber 30 from the first opening, and enters the air inlet channel 40 from the air inlet under the obstruction of the aerosol generating article 2000 inserted in the containment chamber 30, and turns around in the interval space to enter the containment chamber 30.

[0048] In a third embodiment, the air inlet portion is connected within the containment chamber 30 and close to the first opening, and the air inlet portion is directly connected to the outside of the main body.

[0049] Further, please refer to Figure 1-5 As shown, the main body includes a first support tube 11 and a second support tube 12. The first support tube 11 is at least partially inserted into the second support tube 12, and the first support tube 11 forms the receiving chamber 30. The second support tube 12 and the outer wall of the first support tube 11 form the air intake channel 40.

[0050] Furthermore, the first support tube 11 has an air inlet 1115 near the first opening end, the air inlet 1115 is connected to the air intake channel 40 and is located near the air intake end. This allows external airflow to first enter the containment chamber 30 and then pass through the air inlet into the air intake channel 40.

[0051] Furthermore, the support member 20 is also configured to have a first support structure 22, which is connected to the sealing structure 21 and extends from the second opening end into the receiving chamber 30 without contacting the first support tube 11.

[0052] The first support structure 22 is used to support and limit the end of the matrix segment of the aerosol generating article 2000 inserted into the receiving chamber 30. The matrix segment 2300 and the nozzle segment 2100 are opposite ends along the length of the aerosol generating article 2000.

[0053] By setting the first support structure 22 to limit the end of the matrix segment 2300, the inserted aerosol generating product 2000 can be prevented from being excessively inserted and protruding from the receiving chamber 30, affecting the smoothness of the airflow in the air intake channel 40 turning around and entering the receiving chamber 30, or even blocking the interval space, causing the airflow in the air intake space to be unable to enter the receiving chamber 30.

[0054] Further, see Figure 5 As shown, the first support structure 22 includes a plurality of first support ribs 221, which are respectively connected to the side of the sealing structure 21 near the receiving chamber 30. The end faces of the plurality of support ribs facing the first opening end respectively provide at least partial limiting support for the aerosol generating article 2000 inserted into the receiving chamber 30.

[0055] In the first embodiment, a plurality of the first support ribs 221 are independently spaced apart from each other, and each supports and limits the aerosol generating product 2000.

[0056] In the second embodiment, each of the first support ribs 221 includes a first part 2211 and a second part 2212, wherein the second part 2212 is connected between the first part 2211 and the sealing structure 21.

[0057] The multiple second parts 2212 are connected with the center line 31 of the containment chamber 30 as a reference, and a first gap 2213 is formed between two adjacent first parts 2211.

[0058] In this embodiment, by interconnecting multiple second portions 2212, the first support structure 22 can be more stably connected to the sealing structure 21, and the aerosol generating article 2000 can be more stably supported and limited. Furthermore, by providing the first notch 2213 between adjacent first portions 2211, the contact area between the first support structure 22 and the aerosol generating article 2000 can be reduced, thereby increasing the airflow rate from the containment chamber 30 into the matrix section 2300, thus reducing suction resistance and improving the smoothness of airflow. In addition, providing the first notch 2213 also provides more space for airflow from the air intake channel 40 to enter the containment chamber 30, further improving the smoothness of airflow within the main body.

[0059] Furthermore, in one embodiment, the first support structure 22 includes three first support ribs 221, with an included angle of 120 degrees between adjacent first support ribs 221. This ensures that the three first support ribs 221 are evenly connected to the sealing structure 21.

[0060] In other embodiments, the first support structure 22 may also include two, four or more, which is not limited here.

[0061] Furthermore, the support member 20 is also configured to form a second support structure 23, which is connected to the sealing structure 21 and extends into the second support tube 12 located on the periphery of the first support structure 22.

[0062] Furthermore, the second support structure 23 is connected to the first support pipe 11 corresponding to the second open end, and has a second notch 232, which connects the air intake channel 40 and the receiving chamber 30. Airflow in the air intake channel 40 enters the space between the second support structure 23 and the first support structure 22 through the second notch 232, and moves from this space into the receiving chamber 30. Part of the airflow will move into the receiving chamber 30 from the first notch 2213.

[0063] Furthermore, in one embodiment, the second support structure 23 includes three second support ribs 231, each second support rib 231 corresponding to a first support rib 221 and located outside the corresponding first support rib 221. Adjacent second support ribs 231 are spaced apart by second notches 232, and each second notch 232 is directly opposite a first notch 2213, thereby further improving the smoothness of airflow from the air intake channel 40 through the second notches 232 into the receiving chamber 30.

[0064] Further, see Figure 2-3 As shown, the main body includes a heating element 13, which is held between the second support structure 23 and the first support tube 11, and the heating element 13 is connected to the first support tube 11 to form the receiving chamber 30.

[0065] During suction, the heating element 13 heats up when energized to heat the matrix section 2300 of the inserted aerosol generating article 2000, thereby causing the heated matrix to generate an aerosol and mix with the incoming airflow, moving together toward the suction nozzle section 2100.

[0066] Furthermore, please refer to Figure 5-6 As shown, the second support structure 23 has a first end face 233 and a second end face 234. The first end face 233 is located inside the second support structure 23 and is close to the sealing structure 21, while the second end face 234 is away from the sealing structure 21.

[0067] The first support tube 11 has a third end face 1113 and a fourth end face 1114. The third end face 1113 is located inside the first support tube 11, and the third end face 1113 is directly opposite to the first end face 233 along the first direction and away from the second opening end. The fourth end face 1114 is directly opposite to the second end face 234 and close to the second opening end.

[0068] The heating element 13 is tubular, and its two ends abut against the first end face 233 and the third end face 1113 respectively along the first direction. The heating element 13 can be formed by winding heating wire, heating mesh, heating plate, etc., into a tubular shape. No limitation is made here.

[0069] Further, see Figure 2-3 As shown, the main body includes a heat sink 14. The heat sink 14 is disposed on the periphery of the heat-generating element 13 and abuts against the second support structure 23 and the first support tube 11.

[0070] Furthermore, the heat sink 14 rests between the second end face 234 and the fourth end face 1114, and is used to dissipate heat from the outside of the heat sink 13 into the air intake channel 40. This allows the airflow entering the air intake channel 40 to be preheated within the air intake channel 40, thereby fully utilizing the heat dissipated by the heat sink 13 to preheat the airflow, improving the utilization rate of the heat emitted by the heat sink 13, and increasing the efficiency of heating and baking the substrate to generate aerosols.

[0071] In addition, by using the heat emitted outward by the heating element 13 to preheat the airflow in the air intake channel 40, and then allowing the airflow in the air intake channel 40 to enter the aerosol generating product 2000, this heat is prevented from accumulating in the main body, thus avoiding high heat in the main body and affecting the user's grip on the main body.

[0072] Furthermore, the heat sink 14 includes a heat sink pipe 141 and a heat sink 142. The heat sink pipe 141 is sleeved on the periphery of the heat-generating component 13 and abuts between the second end face 234 and the fourth end face 1114. The heat sink 142 is connected to the outside of the heat sink pipe 141 and extends into the air intake channel 40.

[0073] By setting the heat sink 142, the heat dissipated by the heat-generating component 13 can enter the air intake channel 40 more efficiently, and when the airflow flows through the heat sink 142 in the air intake channel 40, there is a larger contact area between the airflow and the heat sink 142, thereby improving the efficiency of airflow preheating.

[0074] In some embodiments, a plurality of heat sinks 142 are evenly distributed on the outer periphery of the heat sink 141, with adjacent heat sinks 142 spaced apart, so that the airflow flowing through the air intake channel 40 can be preheated evenly.

[0075] In one embodiment, see Figure 2-4 As shown, the first support tube 11 includes a first tube body 111 and a second tube body 112 connected to each other. The first tube body 111 is inserted into the second support tube 12, and the second tube body 112 extends out of the second support tube 12. The connection between the first tube body 111 and the second tube body 112 blocks the end of the second tube body 112 near the air inlet.

[0076] The first tube 111 is provided with a plurality of air inlets 1115, which are evenly distributed on the peripheral wall of the first tube 111, so that airflow can enter the air intake channel 40 evenly from the plurality of air inlets 1115.

[0077] Furthermore, the first pipe body 111 includes a variable diameter section 1111 and a constant diameter section 1112 that are connected to each other. The variable diameter section 1111 is connected between the second pipe body 112 and the constant diameter section 1112.

[0078] Furthermore, the constant diameter section 1112 is close to the second opening end, the diameter of the variable diameter section 1111 gradually increases along the direction from the second opening end to the first opening end, and the air inlet 1115 is opened in the variable diameter section 1111.

[0079] When the aerosol generating article 2000 is inserted into the receiving chamber 30, the outer wall of the aerosol generating article 2000 and the inner wall of the corresponding variable diameter section 1111 of the receiving chamber 30 are spaced apart from each other, so that external airflow can enter the air intake channel 40 from the air inlet 1115.

[0080] Furthermore, the aerosol generating article 2000 also includes a cooling section 2200 connected between the mouthpiece section 2100 and the matrix section 2300. The cooling section 2200 is used to cool the aerosol so that the temperature of the aerosol inhaled by the user from the mouthpiece section 2100 is suitable, and to prevent the mouthpiece section 2100 from becoming too hot and causing burns.

[0081] Therefore, by opening the air inlet 1115 on the variable diameter section 1111, the external airflow will cool the outer periphery of the cooling section 2200 before entering the air intake channel 40, thereby improving the cooling effect of the cooling section 2200 on the flowing aerosol.

[0082] Further, please refer to Figure 2-4 As shown, the main body includes an elastic element 15. The elastic element 15 is disposed within the receiving chamber 30 and is used to elastically clamp the aerosol generating article 2000 inserted into the receiving chamber 30.

[0083] Furthermore, the elastic member 15 includes a ring portion 151 and a protrusion 152. The protrusion 152 is disposed inside the ring portion 151 and is used to clamp the aerosol generating article 2000 inserted into the receiving chamber 30. This prevents the inserted aerosol generating article 2000 from exiting the receiving chamber 30 in the second direction.

[0084] Furthermore, the inner side of the ring portion 151 is provided with at least one of the protrusions 152, which is not limited here.

[0085] In one embodiment, the inner side of the ring portion 151 is provided with three protrusions 152, which are evenly distributed on the inner side of the ring portion 151 relative to the central axis of the ring portion 151. This ensures that the inserted aerosol generating article 2000 is located within the receiving chamber 30 along the central axis of the ring portion 151. This prevents the inserted aerosol generating article 2000 from blocking the air inlet 1115, allowing external airflow to enter the receiving chamber 30 through the gap between the ring portion 151 and the corresponding aerosol generating article 2000, and then enter the air intake channel 40 through the air inlet 1115 opened on the variable diameter section 1111.

[0086] In another embodiment, four protrusions 152 are evenly provided on the inner side of the ring portion 151. Further details will not be provided here.

[0087] On the other hand, please see Figure 7-9 and combined Figure 1-3 As shown, this application also provides a heat-not-burning device 1000, which includes the aforementioned air intake structure 100. Therefore, the heat-not-burning device 1000 possesses all the technical effects of the aforementioned air intake structure 100. Since the technical effects of the air intake structure 100 have been described in detail above, they will not be repeated here.

[0088] Furthermore, the heated non-combustible device 1000 also includes a housing 200. The air intake structure 100 is housed within the housing 200. The housing 200 is provided with an insertion hole 210, which connects to the receiving chamber 30 from the first opening end.

[0089] The aerosol generating article 2000 enters the housing 200 through the insertion hole 210 and is inserted into the receiving chamber 30. External airflow enters the heated non-combustible device 1000 through the insertion hole 210, and after entering the receiving chamber 30 from the first opening end, it enters the air intake channel 40 along the air inlet 1115 on the variable diameter section 1111, and then passes through the second notch 232 to enter the receiving chamber 30 from the second opening end, and enters the matrix section 2300 of the aerosol generating article 2000 in the second direction within the receiving chamber 30.

[0090] Furthermore, the heating non-combustible device 1000 also includes a storage battery 300 and a circuit board 400, which are respectively housed within the housing 200, and the circuit board 400 is electrically connected between the storage battery 300 and the heating element.

[0091] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0092] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0093] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
