[0038] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0039] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence 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 certain embodiment and do not mean that the composition and / or sequence are necessary.

[0040] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0041] The embodiment of the present application provides an atomization device 100 and a heat-without-combustion device, wherein the heat-without-combustion device comprises a housing, a power supply component and the atomization device 100; the power supply component and the atomization device 100 are both arranged in the housing and electrically connected, the power supply component is used to supply power to the atomization device 100, and the atomization device 100 is used to atomize an aerosol product 200 to generate an aerosol.

[0042] The aerosol product 200 may be medicine, tobacco, fragrance, etc. in solid, liquid, or solid-liquid mixed forms. The aerosol generated by atomization of the aerosol product 200 is a colloidal dispersion system composed of small solid or liquid particles dispersed and suspended in a gas medium.

[0043] The shell can be understood as a collection of related structural parts that constitute the basic structural framework and outer contour of the heat-not-burn device. For example, the shell can adopt a rectangular hollow structure constructed by combining multiple structural parts; the atomization device 100 and the power supply assembly are both installed in the shell to form a complete heat-not-burn device; the user can hold, move, operate and use the heat-not-burn device with the help of the shell.

[0044] The power supply assembly includes a power supply and a circuit board. The circuit board is electrically connected to the power supply. The atomizing device 100 can be electrically connected to the power supply or to the circuit board. After the atomizing device 100 is powered on, heat can be generated by resistance heating and / or electromagnetic induction heating to heat and atomize the aerosol product 200 to generate an aerosol.

[0045] See also Figures 1 to 7 The atomizing device 100 includes a receiving assembly 10, which has an insertion end 11 and a limiting end 12 which are opposite to each other along its axial direction. A receiving cavity 13 is formed inside the receiving assembly 10, and an insertion port 14 communicating with the receiving cavity 13 is provided at the insertion end 11, and an air guide hole 15 communicating with the receiving cavity 13 is provided at the limiting end 12. The insertion port 14 is used for inserting the aerosol product 200 into the receiving cavity 13, and the air guide hole 15 is at least used for air to pass through and enter the receiving cavity 13. The aerosol product 200 is inserted into the receiving cavity 13 through the insertion port 14, and the limiting end 12 limits it, so that the aerosol product 200 can be stably placed in the atomizing device 100.

[0046] By providing the air guide hole 15, the gas outside the atomizing device 100 can enter the receiving chamber 13 through the air guide hole 15. In specific implementation, when there is suction outside the atomizing device 100, the airflow enters the receiving chamber 13 through the air guide hole 15 under the action of the suction, and then enters the aerosol product 200, and the aerosol generated by the atomization of the aerosol product 200 can be discharged from the atomizing device 100 along with the airflow.

[0047] See also Figure 3 and Figure 5 The atomizing device 100 further includes a liquid collecting member 20, which is disposed at the limiting end 12. A liquid collecting chamber 30 is formed between the liquid collecting member 20 and the receiving assembly 10. The air guide hole 15 connects the receiving chamber 13 and the liquid collecting chamber 30. The liquid collecting chamber 30 is used to collect the liquid formed inside the atomizing device 100.

[0048] When the suction force outside the atomizer 100 disappears, the aerosol can enter the inside of the atomizer 100 from the receiving chamber 13 through the air guide hole 15, and the condensate generated after condensation pollutes the atomizer 100. By setting a liquid collecting chamber 30, the liquid collecting chamber 30 is connected with the receiving chamber 13 through the air guide hole 15, and the aerosol is discharged from the receiving chamber 13 to the liquid collecting chamber 30 through the air guide hole. The condensate generated after condensation can be gathered in the liquid collecting chamber 30, thereby avoiding polluting the inside of the atomizer 100. In addition, when the heat-not-burn device is in use or the bottom of the heat-not-burn device is located at the bottom, the receiving chamber 13 is usually located above the air guide hole 15. The condensate generated by the condensation of the aerosol in the receiving chamber 13 can enter the atomizer 100 through the air guide hole 15, thereby also causing polluting the atomizer 100. The condensate from the receiving chamber 13 is collected by setting the liquid collecting chamber 30, thereby avoiding polluting the atomizer 100 with the condensate.

[0049] When the amount of liquid collected in the liquid collecting chamber 30 reaches a certain amount, the atomizing device 100 can be flipped over so that the liquid collecting chamber 30 is located above the receiving chamber 13. Under the action of its own gravity, the liquid flows from the liquid collecting chamber 30 to the limiting end 12 of the receiving assembly 10, flows into the receiving chamber 13 through the air guide hole 15, and then flows out of the atomizing device 100 through the insertion port 14, thereby realizing the discharge of the liquid in the liquid collecting chamber 30. Therefore, the atomizing device 100 provided in this embodiment forms a liquid collecting chamber 30 between the liquid collecting chamber 20 and the receiving assembly 10 by disposing a liquid collecting part 20 at the limiting end 12 of the receiving assembly 10. When the condensate needs to be discharged, it can be realized by flipping the atomizing device 100 so that the liquid collecting chamber 30 is located above the receiving chamber 13. The atomizing device 100 has a simple structure, is easy to assemble, and does not increase the cost.

[0050] See also Figure 4 and Figure 5 A guide protrusion 40 is provided in the liquid collecting chamber 30. The guide protrusion 40 protrudes from the liquid collecting part 20 on the axial side toward the air guide hole 15. The guide protrusion 40 is used to guide the liquid in the liquid collecting chamber 30 into the receiving chamber 13 through the air guide hole 15. When the atomizing device 100 is turned over, the guide protrusion 40 is turned over to the top of the receiving assembly 10 together with the liquid collecting part 20, and the liquid in the liquid collecting chamber 30 can gradually flow to the air guide hole 15 along the guide protrusion 40. Such a configuration, on the one hand, helps to guide the liquid in the liquid collecting chamber 30 to the air guide hole 15; on the other hand, it can prevent a large amount of liquid from quickly gathering at the limiting end 12 of the receiving assembly 10 in a short period of time.

[0051] See also Figure 5In one embodiment, the flow guiding protrusion 40 includes a protrusion 41, and the protrusion 41 is arranged in the middle part of the liquid collecting chamber 30. The protrusion 41 is arranged in the middle part of the liquid collecting chamber 30, and is offset to one side of the liquid collecting chamber 30 relative to the protrusion 41. The protrusion 41 can guide most of the liquid in the liquid collecting chamber 30, which helps the liquid in the liquid collecting chamber 30 flow to the air guide hole 15. Of course, in other embodiments, the flow guiding protrusion 40 can also include at least two protrusions 41. When this arrangement is adopted, each protrusion 41 can be arranged at intervals.

[0052] In one embodiment, any sectional surface of the flow-guiding protrusion 40 in the axial direction has a first outer contour line, and the surface formed by the first outer contour lines of all sectional surfaces of the flow-guiding protrusion 40 is set toward the air guide hole 15; any sectional surface of the liquid collecting part 20 in the axial direction has a second outer contour line, and the surface formed by the second outer contour lines of all cross sections of the liquid collecting part 20 is set toward the air guide hole 15; the angle α between the first outer contour line and the reference plane is greater than the angle β between the second outer contour line and the reference plane, and the reference plane is a plane perpendicular to the axial geometric center line of the receiving component 10. Such a configuration makes the flow-guiding protrusion 40 relatively more abrupt, which is more conducive to the flow of liquid along the flow-guiding protrusion 40.

[0053] See also Figure 3 and Figure 5 , the receiving assembly 10 includes a receiving member 16 and a limiting member 17; the limiting member 17 is connected to one end of the receiving member 16, and is enclosed with the receiving member 16 to form a receiving cavity 13, the insertion port 14 is opened at the end of the receiving member 16 away from the limiting member 17, and the air guide hole 15 is opened at the end of the limiting member 17 away from the receiving member 16; the liquid collecting member 20 is connected to the limiting member 17, and a liquid collecting cavity 30 is formed between the limiting member 17 and the liquid collecting cavity 30. The end of the receiving member 16 away from the limiting member 17 forms the insertion end 11 of the receiving assembly 10, and the end of the limiting member 17 away from the receiving member 16 forms the limiting end 12 of the receiving assembly 10. Specifically, the receiving member 16 is a hollow cylindrical structure with two ends open, and the limiting member 17 is a hollow cylindrical structure with one end open. The receiving member 16 is inserted in the limiting member 17, and the cavity of the receiving member 16 and the cavity of the limiting member 17 enclose to form the receiving cavity 13.

[0054] Please refer to Tu 2, Figure 5 , Figure 8 and Fig. 9, a first groove 21 is provided on the side of the liquid collecting member 20 facing the air guide hole 15, and a second groove 18 is also provided on the end of the limiting member 17 away from the receiving member 16. The air guide hole 15 connects the second groove 18 and the receiving chamber 13, and the first groove 21 and the second groove 18 enclose a liquid collecting chamber 30. Among them, the notch of the first groove 21 and the notch of the second groove 18 are arranged relative to each other, so that the first groove 21 and the second groove 18 enclose a liquid collecting chamber 30. By providing the second groove 18, when the atomizing device 100 is turned over, the liquid can first gather in the second groove 18, and then gradually flow into the receiving chamber 13 through the air guide hole 15. In this way, it can be avoided that a large amount of liquid gathers in one end of the air guide hole 15 facing the liquid collecting chamber 30 in a short time and overflows circumferentially to the limiting member 17, which plays a buffering role for the liquid flowing from the liquid collecting chamber 30 to the receiving chamber 13.

[0055] It can be understood that in other embodiments, the first groove 21 is provided on the side of the liquid collecting member 20 facing the air guide hole 15, the limiting member 17 is not provided with the second groove 18, and the first groove 21 can also form the liquid collecting chamber 30; or, the second groove 18 is provided on the end of the limiting member 17 away from the receiving member 16, the liquid collecting member 20 is not provided with the first groove 21, and the second groove 18 can also form the liquid collecting chamber 30.

[0056] In one embodiment, the second groove 18 is a conical groove or a hemispherical groove. This is conducive to the liquid gathering in the second groove 18. It is understood that the second groove 18 can also be set to other shapes, such as the groove bottom wall of the second groove 18 is a plane, and the groove side wall extends from the groove opening toward the groove bottom wall in a direction gradually approaching its geometric center.

[0057] Among them, at least one of the receiving member 16 and the limiting member 17 is a heating component, which is used to generate heat for the aerosol product 200 to generate aerosol. When the receiving member 16 is a heating component, since the receiving member 16 is arranged around the circumference of the aerosol product 200, the receiving member 16 can heat the aerosol product 200 from the circumference thereof; when the limiting member 17 is a heating component, since the airflow enters the receiving cavity 13 through the air guide hole 15 and then enters the aerosol product 200, the limiting member 17 can heat the airflow passing through the air guide hole 15 to form a hot airflow, and the hot airflow enters the interior of the aerosol product 200 to heat it. In specific implementation, the heating component can be heated by resistance heating or by magnetic induction.

[0058] In one embodiment, the receiving member 16 is a heating component, and the limiting member 17 is a heat-conducting component. The receiving member 16 is used to generate heat for the aerosol product 200 to generate aerosol, and the limiting member 17 is used to conduct the heat generated by the receiving member 16. Since the limiting member 17 has thermal conductivity, the limiting member 17 can conduct the heat generated by the receiving member 16 to the airflow flowing through the air guide hole 15, thereby heating the airflow. Therefore, the receiving assembly 10 provided in this embodiment can heat the aerosol product 200 by directly heating the circumference of the aerosol product 200 on the one hand; and can heat the aerosol product 200 by heating the airflow that is about to flow into the aerosol product 200 on the other hand.

[0059] Furthermore, when the atomizing device 100 is turned over and the liquid in the liquid collecting chamber 30 flows to the stopper 17, the stopper 17 has thermal conductivity, so that the liquid can be heated to reduce the viscosity of the liquid, and even the liquid can be heated to generate aerosol, which is conducive to the discharge of the liquid. In addition, the stopper 17 is set to have thermal conductivity, and the stopper 17 conducts the heat generated by the receiving member 16, and the heat can be radiated to the liquid collecting chamber 30, thereby reducing the viscosity of the liquid in the liquid collecting chamber 30. When the atomizing device 100 is turned over, it is conducive to the liquid flowing to the stopper 17.

[0060] In a specific implementation, when the atomizing device 100 is turned over and the liquid in the liquid collecting chamber 30 flows into the receiving chamber 13, the receiving component 16 can be energized to heat the liquid in the receiving chamber 13 to generate aerosol to be discharged from the atomizing device 100, or the receiving component 16 can be de-energized to allow the liquid to flow out of the receiving chamber 13 directly.

[0061] See also Figure 1 , Figure 3 and Figure 5 The atomizing device 100 further includes a sleeve assembly 50, which is connected to the liquid collecting member 20 and sleeved on the outer periphery of the receiving assembly 10; the sleeve assembly 50 is provided with an air inlet channel 51, which is connected to the liquid collecting chamber 30 and is used to guide the gas outside the atomizing device 100 into the liquid collecting chamber 30. In a specific implementation, the gas outside the atomizing device 100 flows to the liquid collecting chamber 30 through the air inlet channel 51, and then flows into the receiving chamber 13 through the air guide hole 15, and then enters the aerosol product 200. The sleeve assembly 50 is used to guide the gas to the liquid collecting chamber 30 on the one hand, and isolate the receiving assembly 10 on the other hand, so as to protect the receiving assembly 10.

[0062] See also Figure 5The sleeve assembly 50 includes a first barrel 52, a second barrel 53 and a cover plate 54; the first barrel 52 is sleeved on the outer periphery of the receiving assembly 10 and is spaced from the receiving assembly 10; the second barrel 53 is sleeved on the outer periphery of the first barrel 52 and is spaced from the first barrel 52; the cover plate 54 is covered on the same end of the first barrel 52 and the second barrel 53, and the ends of the first barrel 52 and the second barrel 53 away from the cover plate 54 are connected to the liquid collecting member 20. A first through hole 55 is penetrated through the cover plate 54, and the first through hole 55 communicates with the gap 56 between the first barrel 52 and the second barrel 53, and forms an air intake channel 51 with the gap 56 between the first barrel 52 and the second barrel 53. Among them, the first barrel 52 can be made of heat-insulating material to insulate the receiving assembly 10 and thus prevent heat loss.

[0063] See also Figure 5 and Fig. 9 The liquid collecting member 20 is provided with a second through hole 22, and the second through hole 22 communicates with the gap 56 between the first cylinder 52 and the second cylinder 53 and the liquid collecting chamber 30, so that the air inlet channel 51 and the liquid collecting chamber 30 are connected. Specifically, the liquid collecting member 20 is provided with a bearing step 23 and an annular groove 24 surrounding the bearing step 23. The receiving assembly 10 and the first cylinder 52 are both supported on the bearing step 23, and the second cylinder 53 is inserted into the annular groove 24. The second through hole 22 is provided on the bearing step 23 and the groove side wall of the annular groove 24 adjacent to the bearing step 23. The liquid collecting member 20 has a simple structure, and is easy and quick to assemble with the receiving assembly 10 and the sleeve assembly 50.

[0064] The atomizing device 100 provided in this embodiment is provided with a liquid collecting member 20 at the limiting end 12 of the receiving assembly 10, and a liquid collecting chamber 30 communicating with the receiving chamber 13 is formed between the liquid collecting member 20 and the receiving assembly 10, so that the condensed liquid inside the atomizing device 100 can be collected, and after the atomizing device 100 is turned over, the liquid in the liquid collecting chamber 30 can be discharged to the receiving chamber 13 under the action of its own gravity, and then discharged from the atomizing device 100. The atomizing device 100 has a simple structure, is easy to assemble, and does not increase the cost.
