[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0031] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0032] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] The aerosol generating device is an electronic device used to atomize a liquid aerosol generating matrix to generate an aerosol for the user to use. The generating device generates moist salt mist, which is blown out through a pipe, and the pipe is heated to convert the moist salt mist into dry salt sol.

[0034] At present, when heating pipelines on the market, multiple heating plates are usually arranged inside the pipelines. As a result, during actual use, due to the evaporation of moist salt mist due to heat, the gaps between the heating plates will be filled with salt crystals precipitated from the evaporated salt mist, thereby corroding the heating plates and reducing the service life of the product. As the heating plates are gradually eroded, the heating efficiency of the device is greatly reduced. In addition, since the heating plates are arranged inside the pipeline, it is very inconvenient to maintain and replace the heating plates.

[0035] Therefore, in order to facilitate the maintenance and care of the aerosol generating device, extend the service life, improve the stability of the heating efficiency, and improve the heating efficiency, this embodiment provides an aerosol generating device.

[0036] like Figures 1 to 4 As shown, the aerosol generating device for generating dry salt sol includes an atomizing generating device 1, an evaporator 2 and an air blowing device 3. The atomizing generating device 1 is used to generate moist salt mist. The evaporator 2 includes an evaporating tube 21 and a heating element 22. The evaporating tube 21 includes a first inlet, a second inlet and a first outlet. The atomizing generating device 1 is connected to the first inlet. The heating element 22 is arranged on the outer wall of the evaporating tube 21 close to the first outlet and is used to heat the salt mist in the evaporating tube 21. The air blowing device 3 is connected to the second inlet and is used to blow the salt mist from the first inlet to the first outlet.

[0037] The aerosol generating device comprises an atomizing generating device 1 for generating moist salt mist, an air blowing device 3 for blowing the salt mist, and an evaporator 2 for heating the salt mist. By arranging a heating element 22 in the evaporator 2 on the outer wall of an evaporating tube 21, it is not only convenient to install, maintain and replace the heating element 22, but also avoids corrosion of the heating element 22 by salt crystallization after evaporation, thereby ensuring the stability and high efficiency of the heating efficiency of the heating element 22. In addition, since corrosion of the heating element 22 is avoided, the service life of the device is extended.

[0038] In this embodiment, when the aerosol generating device is in use, the atomization generating device 1 generates a moist salt mist with a high water content, and enters the evaporation tube 21 in the evaporator 2. Then, the blowing device 3 supplies air volume to drive the salt mist generated by the atomization generating device 1 to flow in the evaporation tube 21. Since the heating element 22 heats the evaporation tube 21, the internal temperature of the evaporation tube 21 is increased under the action of heat transfer, thereby heating the moist salt mist flowing in the evaporation tube 21, thereby obtaining a dry salt sol, which is finally inhaled by the patient and enters the alveoli to achieve the treatment of the respiratory tract.

[0039] Alternatively, if Figure 1 , Figure 2 As shown, the evaporator 2 further includes a connecting pipe 23, one end of which is connected to the air blowing device 3, and the other end of which is connected to the second inlet of the evaporation tube 21. By providing the connecting pipe 23, it is convenient to connect the evaporation tube 21 of the evaporator 2 with the air blowing device 3, so that the air volume supplied by the air blowing device 3 enters the evaporation tube 21 through the connecting pipe 23. In this embodiment, the connecting pipe 23 and the evaporation tube 21 are manufactured by an integrated molding process, wherein the air blowing device 3 is a blower.

[0040] Alternatively, if Figure 2 , Figure 3 As shown, the angle between the central axis of the connecting pipe 23 and the central axis of the evaporating tube 21 is 30°. Since the angle between the central axis of the connecting pipe 23 and the central axis of the evaporating tube 21 is 30°, the direction of the airflow blown out by the blowing device 3 changes at an obtuse angle when it blows from the connecting pipe 23 to the evaporating tube 21, thereby making the airflow flow smoother, and it is not easy for salt crystals to accumulate at the junction of the connecting pipe 23 and the evaporating tube 21, the cleaning frequency is low, and maintenance is convenient. In this embodiment, in addition to 30°, the central axis of the connecting pipe 23 and the central axis of the evaporating tube 21 can also be other acute angles, so as to ensure that when the airflow blows from the connecting pipe 23 to the first outlet of the evaporating tube 21, the direction of the airflow changes at an obtuse angle.

[0041] Alternatively, if Figure 2 , Figure 3 As shown, the evaporator 2 further includes a connector 24, which is used to connect the air blowing device 3 to the connecting pipe 23. By providing the connector 24, it is convenient to connect and fix the air blowing device 3 to the connecting pipe 23. In this embodiment, the connecting pipe 23, the connector 24 and the evaporation tube 21 are manufactured by an integrated molding process. The connector 24 is provided with a connecting end surface on one side facing the air blowing device 3, so as to facilitate detachable connection with the air blowing device 3 by bolts.

[0042] Alternatively, if Figure 2 , Figure 3As shown, the connector 24 is provided with an air storage chamber 241 and a confluence chamber 242, the air blowing device 3 is connected to the side of the connector 24 provided with the air storage chamber 241, and the side of the connector 24 provided with the confluence chamber 242 is connected to the connecting pipe 23, and the confluence chamber 242 is funnel-shaped, with its large diameter end communicating with the air storage chamber 241, and its small diameter end communicating with the connecting pipe 23. By providing the air storage chamber 241 in the connector 24, the wind blown out by the air blowing device 3 is buffered, the wind speed is reduced, and the wet salt mist is prevented from being blown out before being completely evaporated due to excessive wind speed, wherein the funnel-shaped confluence chamber 242 is provided, so as to collect the wind dispersed by the air storage chamber 241, and ensure the amount of wind blown to the evaporation pipe 21.

[0043] Alternatively, if Figure 2 , Figure 4 As shown, a docking groove 211 is provided on the side of the evaporation tube 21 facing the atomization generating device 1, a first inlet is provided in the docking groove 211, and a docking protrusion 11 is provided on the atomization generating device 1, and the docking protrusion 11 is inserted into the docking groove 211. By providing the docking groove 211 on the side of the evaporation tube 21 facing the atomization generating device 1 and providing the docking protrusion 11 on the atomization generating device 1, it is convenient to dock the atomization generating device 1 with the evaporation tube 21, and by covering the docking groove 211 with the docking groove 211, the sealing of the docking point between the atomization generating device 1 and the evaporation tube 21 is achieved, and the leakage of salt mist is effectively avoided.

[0044] In this embodiment, a plurality of mounting grooves 12 are further provided on the outer side of the docking protrusion 11 , and the mounting grooves 12 are used to install sealing rings, and the gap between the outer wall of the docking protrusion 11 and the inner wall of the docking groove 211 is sealed by the sealing rings.

[0045] Alternatively, if Figure 1 , Figure 2 As shown, a connecting ear 212 is provided on the side of the evaporation tube 21 facing the atomization generating device 1, and the connecting ear 212 is used to connect the atomization generating device 1 and the evaporation tube 21. By providing the connecting ear 212 on the side of the evaporation tube 21 facing the atomization generating device 1, it is convenient to detachably connect the atomization generating device 1 and the evaporation tube 21 by bolts, thereby facilitating the disassembly and assembly of the atomization generating device 1. In this embodiment, a pair of connecting ears 212 are provided on the side of the evaporation tube 21 facing the atomization generating device 1, thereby ensuring the firmness of the connection.

[0046] Alternatively, if Figure 1 , Figure 2As shown, the heating element 22 is in the form of a wire, and the heating element 22 is evenly wound on the outer wall of the evaporation tube 21 near the first outlet. By adopting the wire-shaped heating element 22, it is convenient to connect and fix the heating element 22 to the outer wall of the evaporation tube 21 in a winding manner. In other embodiments, in addition to adopting the wire-shaped heating element 22, a heating sleeve can also be adopted, and the heating sleeve is set on the outer side of the evaporation tube 21, so that the evaporation tube 21 can also be heated. In addition, the heating element 22 can also be set in the form of a sheet, and multiple pieces of heating elements 22 are evenly attached to the outer wall of the evaporation tube 21. Compared with the use of the wire-shaped heating element 22 in this embodiment, whether the heating sleeve or the sheet-shaped heating element 22 is used, it is necessary to fix it on the outer wall of the evaporation tube 21 by bonding.

[0047] Alternatively, if Figure 1 As shown, a winding groove is provided on the outer wall of the evaporation tube 21, and the filamentary heating element 22 is embedded in the winding groove. By providing a winding groove on the outer wall of the evaporation tube 21, the filamentary heating element 22 is embedded in the winding groove, thereby achieving the fixing and positioning of the filamentary heating element 22 on the evaporation tube 21, without the need for connection by bonding, and when replacement is required, the filamentary heating element 22 can be directly replaced.

[0048] Optionally, the heating element 22 is made of graphene material. It has high thermal conductivity, electrical conductivity, and thermal stability, so that it can achieve rapid heating and maintain stability at high temperatures, avoiding the hidden dangers of performance degradation or decomposition of other materials at high temperatures, thereby increasing the service life of the aerosol generating device.

[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
