[0059] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0061] In this application, unless otherwise indicated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of a device in actual use or operation, specifically in the drawing directions of the accompanying drawings; whereas "inner" and "outer" refer to the outline of the device. Furthermore, in the description of this application, the term "including" means "including but not limited to." Terms such as first, second, and third are used merely as labels and do not impose numerical requirements or establish a sequence.

[0062] In this application, "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. A and B can be singular or plural.

[0063] In this application, "at least one" means one or more, and "plurality" means two or more. "One or more", "at least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of a, b, or c", or "at least one of a, b, and c" can all mean: a, b, c, ab (i.e., a and b), ac, bc, or abc, where a, b, and c can be single or plural, respectively.

[0064] The technical solution of this application is as follows:

[0065] First, refer to Figures 1 to 3 As shown, an embodiment of the present application provides an atomizer 100 , including: a housing 110 , an atomizing tube 150 , a base 160 , an atomizing core 120 and a liquid guide 130 .

[0066] The housing 110 has an interior space and a nozzle 112. An atomizer tube 150 is disposed within the interior space to divide the interior space into a liquid storage chamber 100a and at least a portion of an atomizing channel 100b. The nozzle 112 forms at least an outlet 100d of the atomizing channel 100b. Exemplarily, the atomizer tube 150 is constructed as a body of revolution about a central axis C1. In a radial direction of the central axis C1, at least a portion of the atomizing channel 100b is located within the atomizer tube 150, and at least a portion of the liquid storage chamber 100a is located between the atomizer tube 150 and the housing 110.

[0067] The base 160 is coupled to the housing 110 to at least enclose the liquid storage chamber 100a. The atomizer core 120 is disposed in the atomizer channel 100b and is used to heat the atomized matrix to generate an aerosol. The aerosol mixes with the airflow in the atomizer channel 100b and then flows out of the outlet 100d of the atomizer channel 100b. The liquid guide 130 is disposed between the liquid storage chamber 100a and the atomizer core 120 to transport the atomized matrix. The term "coupled" in this application can be understood as a method of securing by snapping, bonding, welding, or other methods.

[0068] The housing 110 further includes an airway portion 113 extending from the nozzle 112 to the interior space. Specifically, the airway within the airway portion 113 connects the atomization channel 100b with the nozzle 112, and at least a portion of the atomization tube 150 is sleeved within the airway portion 113. A gap is provided between the base 160 and the atomization tube 150 to form a flow port 100e. The liquid storage chamber 100a transfers the atomized matrix to the liquid guide 130 through the flow port 100e.

[0069] By adopting the above technical solution, the airway portion 113 is formed by extending the suction nozzle 112 into the internal space, and the atomizer tube 150 is sleeved on the airway portion 113, so that the two have a larger contact surface to improve the connection stability, and this installation method is convenient for assembly; at the same time, there is a distance between the base 160 and the atomizer tube 150 to form the flow port 100e, that is, the atomizer tube 150 does not need the support of the base 160, which reduces the assembly of the base 160 and the atomizer tube 150, simplifies the assembly process, and is conducive to automated assembly.

[0070] Optionally, the liquid guide 130 may be made of oil-conducting cotton or ceramic material.

[0071] In some embodiments, the nozzle 112 is formed with two airway portions 113 , and accordingly, the atomization tube 150 and the atomization core 120 are each provided in two groups to improve atomization efficiency.

[0072] As a preferred solution, the nozzle 112 is integrally formed with the housing 110 to simplify the components of the atomizer 100. The housing 110 can be made of a transparent or translucent material to facilitate observation of the remaining amount and color change of the atomized matrix in the atomizer 100.

[0073] In some embodiments, reference Figure 12 As shown, the atomizer 100 further includes a mouthpiece plug 188. The mouthpiece plug 188 is at least partially inserted into the mouthpiece 112.

[0074] In some embodiments, the atomizing tube 150 is interference-fitted with the airway portion 113. This can increase the firmness of the assembly between the atomizing tube 150 and the airway portion 113 and facilitate assembly.

[0075] In some embodiments, reference Figures 3 to 5 At least part of the liquid guide 130 is located within the atomizer tube 150, which constrains the liquid guide 130 to ensure the shape of the liquid guide 130 is stable. The liquid guide 130 has a central air channel 130a that runs axially through it, that is, the central air channel 130a constitutes a portion of the atomizer channel 100b. The atomizer core 120 is located within the liquid guide 130, and the liquid guide 130 and the atomizer core 120 are respectively fixed to the base 160. In this way, the base 160 supports the liquid guide 130 and the atomizer core 120, improving the stability of the liquid guide 130 and the atomizer core 120.

[0076] In some embodiments, reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The nebulizer 100 further includes a sealing member 140. At least a portion of the sealing member 140 is disposed between the atomizing tube 150 and the airway portion 113. The sealing member 140 seals the assembly gap between the atomizing tube 150 and the airway portion 113, preventing the atomized matrix from flowing through the assembly gap and preventing unexpected leakage of the atomized matrix.

[0077] The atomizing core 120 is disposed between the flow port 100e and the sealing member 140. For example, in the extending direction of the atomizing channel 100b, the atomizing core 120 is disposed between the flow port 100e and the sealing member 140.

[0078] The sealing member 140 may be completely disposed in the assembly gap between the atomizing tube 150 and the airway portion 113 , or the sealing member 140 may be only partially disposed in the assembly gap between the atomizing tube 150 and the airway portion 113 .

[0079] As a preferred solution, the seal 140 is respectively interference-fitted with the atomizer tube 150 and the airway portion 113. With this solution, the seal 140, the atomizer tube 150, and the airway portion 113 are assembled by interference fit, which can increase the firmness of the assembly between the atomizer tube 150 and the airway portion 113 and eliminate the need for additional support at the end of the atomizer tube 150 away from the seal 140, thereby simplifying the assembly process and improving assembly efficiency. At the same time, the interference fit method can achieve sealing between the seal 140 and the airway portion 113, as well as between the seal 140 and the atomizer tube 150, and the sealing structure is simple.

[0080] In some embodiments, reference Figure 1 and Figure 4 As shown, the liquid guiding element 130 abuts against the sealing element 140 and / or the airway portion 113 in the axial direction, and the sealing element 140 or the airway portion 113 is reused to achieve axial positioning of the liquid guiding element 130 .

[0081] In some embodiments, reference Figures 7 to 10 As shown, the sealing member 140 has a first protruding ring 141, which is disposed around the outer wall of the sealing member 140 and contacts the atomizing tube 150 to prevent the atomized matrix in the liquid storage chamber 100a from being transferred to the liquid guide 130 via the first protruding ring 141. In other words, the first protruding ring 141 seals the assembly gap between the sealing member 140 and the atomizing tube 150.

[0082] In some embodiments, the sealing member 140 has a second protruding ring 142 that surrounds the inner wall of the sealing member 140 and contacts the airway portion 113 to prevent the aerosolized matrix in the liquid storage chamber 100a from being transferred to the liquid guide 130 via the second protruding ring 142. In other words, the second protruding ring 142 seals the assembly gap between the sealing member 140 and the housing 110.

[0083] With such a solution, by setting the first convex ring 141 and the second convex ring 142, when the seal 140 is assembled between the airway portion 113 and the atomizer tube 150, the first convex ring 141 and the second convex ring 142 are squeezed and formed, and then fit tightly with the atomizer tube 150 and the airway portion 113, achieving a sealing effect. The sealing structure is simple, which facilitates the processing and assembly of the seal 140.

[0084] As a preferred solution, refer to Figures 7 to 10 As shown, a plurality of first protruding rings 141 are arranged at intervals in the axial direction, thereby forming multiple seals in the axial direction. A plurality of second protruding rings 142 are arranged at intervals in the axial direction, thereby forming multiple seals in the axial direction.

[0085] In the axial direction, the first protruding ring 141 and the second protruding ring 142 are located at the same position and correspond one to one, thereby further improving the sealing effect.

[0086] In some embodiments, reference Figure 1 As shown, a first end of the atomizing tube 150 is coupled to the airway portion 113 via a seal 140 , and a flow port 100 e is provided at a second end of the atomizing tube 150 .

[0087] It is understood that the first end of the atomizing tube 150 is close to the outlet 100d of the atomizing channel 100b to prevent the atomized matrix from flowing into the atomizing channel 100b from the assembly gap between the first end of the atomizing tube 150 and the airway portion 113 when the nebulizer 100 is inverted.

[0088] In some embodiments, reference Figure 1 、 Figure 2 、 Figure 9 and Figure 10 As shown, the airway portion 113 has a first limiting boss 111, and the sealing member 140 abuts against the first limiting boss 111 along a preset direction; the sealing member 140 has a second limiting boss 143, and the first end of the atomizing tube 150 abuts against the second limiting boss 143 along the preset direction.

[0089] For example, the preset direction of the present application is the axial direction of the central axis C1. Of course, the preset direction can also be selected according to the specific assembly method, and there is no specific limitation on this.

[0090] With this solution, the first limiting boss 111 and the second limiting boss 143 are provided to achieve positioning of the sealing member 140 and the atomizing tube 150 relative to the airway portion 113 , thereby facilitating assembly of the sealing member 140 and the atomizing tube 150 .

[0091] In some embodiments, reference Figure 2 As shown, there is a distance between at least part of the sealing member 140 and the liquid-conducting liquid 130 to form an accommodating space 140 a.

[0092] With this solution, by setting up the accommodating space 140a, when the atomizer 100 is inverted, the atomized matrix leaked from the liquid guide 130 can be temporarily stored in the accommodating space 140a, preventing the atomized matrix from entering the atomizing channel 100b and flowing out from the outlet 100d of the atomizing channel 100b.

[0093] In some embodiments, reference Figure 2 、 Figures 7 to 11 As shown, the seal 140 has a raised portion 144 .

[0094] Specifically, a plurality of raised portions 144 are provided, which are arranged at one end of the sealing member 140 close to the liquid-guiding member 130 and respectively abut against the liquid-guiding member 130; the accommodating space 140a at least includes the gaps between adjacent raised portions 144, and the accommodating space 140a is surrounded by the sealing member 140, the liquid-guiding member 130, the atomizing tube 150 and a portion of the airway portion 113.

[0095] With this solution, the accommodating space 140 a is formed by the protrusions 144 arranged at intervals, and the protrusions 144 are reused to position the liquid guide 130 .

[0096] In some embodiments, reference Figure 11 As shown, a first radial width W1 of the protrusion 144 is smaller than a second radial width W2 of an end surface 145 of the sealing member 140 on a side close to the liquid-conducting body 130 .

[0097] By adopting such a solution, the gaps between all adjacent protrusions 144 can be communicated with each other, so that the leaked atomized substrate is evenly distributed in the accommodating space 140 a.

[0098] As another optional solution, the seal 140 may not be provided with the protrusion 144, and there is a gap between the entire end surface 145 of the seal 140 close to the liquid-conducting liquid 130 and the liquid-conducting liquid 130, thereby forming a receiving space 140a between the end surface 145 and the liquid-conducting liquid 130.

[0099] In some embodiments, the housing 110 , the seal 140 and the atomizing tube 150 are integrally formed so that only the flow port 100 e exists between the liquid storage chamber 100 a and the atomizing channel 100 b , thereby avoiding possible leakage risks and simplifying the assembly process.

[0100] In some embodiments, reference Figure 1 、 Figure 3 、 Figures 12 to 14 As shown, the atomizer 100 further includes: a liquid injection plug 181 , a bottom cover 182 and a covering member 183 .

[0101] Specifically, the base 160 is mounted on the end of the housing 110 away from the nozzle 112 and serves to at least seal the liquid storage chamber 100a. The atomizer core 120 is mounted to the base 160 via a support 170, securing the atomizer core 120 to the base 160. A flow port 100e is formed between the atomizer tube 150 and the base 160.

[0102] The base 160 is formed with an inner space 160a, a seat hole 160b and an injection hole 160c. The seat hole 160b is arranged axially and is connected to the inner space 160a. The seat hole 160b at least constitutes the entrance 100c of the atomization channel 100b and a part of the atomization channel 100b. The injection hole 160c is connected to the liquid storage chamber 100a and is used to inject the atomized matrix into the liquid storage chamber 100a. The injection plug 181 is at least partially inserted into the injection hole 160c to block the injection hole 160c. The bottom cover 182 is provided on the base 160 to close the inner space 160a. The cover 183 covers the side of the bottom cover 182 away from the base 160 and part of the base 160 and the housing 110, and is used to cover the specific installation gap between the bottom cover 182, the base 160 and the housing 110 to improve the aesthetics. Specifically, the cover 183 is an iron shell structure.

[0103] In some embodiments, reference Figure 1 、 Figure 3 、 Figures 12 to 14 The atomizer 100 further includes an electrode 184 . The electrode 184 is fixed to the bottom cover 182 and at least partially extends through the bottom cover 182 into the inner space 160 a of the base. The pin 121 of the atomizer core 120 is connected to the electrode 184 .

[0104] In some embodiments, the atomizer 100 further includes: oil-absorbing cotton 185; the oil-absorbing cotton 185 is arranged in the seat space and corresponds to the seat hole 160b, and is used to absorb part of the atomized matrix droplets dropped from the atomizing channel 100b, and can also filter the airflow entering the seat hole 160b.

[0105] In some embodiments, reference Figure 1 、 Figure 3 、 Figures 12 to 14 The atomizer 100 further includes a first sealing ring 186 and a second sealing ring 187. The first sealing ring 186 is disposed between the base 160 and the housing 110 to seal the gap therebetween. The second sealing ring 187 is disposed between the bottom cover 182 and the base 160 to seal the gap therebetween.

[0106] Secondly, refer to Figure 15 and Figure 16 As shown, an embodiment of the present application further provides an aerosol generating device 10, comprising a host 200 and the atomizer 100 as described above.

[0107] Specifically, a control component and a power supply component can be set in the host 200. When the atomizer 100 is connected to the host 200, the power supply component can provide electrical energy to the atomizer core 120 of the atomizer 100, so that the atomizer core 120 generates heat. The specific way in which the atomizer core 120 generates heat depends on the type of atomizer core 120. For example, when the atomizer core 120 includes a structure such as a heating wire, current is directly provided to the atomizer core 120, so that the heating wire heats up. When the atomizer core 120 is a conductor, a changing magnetic field can be provided to the atomizer core 120 to stimulate the atomizer core 120 to generate eddy current to generate heat.

[0108] The control assembly in the main unit 200 may also be provided with a microphone. When the atomizer 100 and the main unit 200 are connected, the microphone can communicate with the atomization channel 100b, so that the microphone can detect the gas flow in the atomization channel 100b, thereby controlling the power supply assembly to provide the mist core with electrical power adapted to the gas flow out of the atomization channel 100b.

[0109] The above is a detailed introduction to the nebulizer and aerosol generating device provided in the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for those skilled in the art, based on the ideas of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present application.
