Description

Technical Field

[0001] This application belongs to the field of atomization technology, and more specifically, relates to a mouthpiece structure, an aerosol generating device, and an electronic atomizer. Background Technology

[0002] An aerosol generating device is a device used to heat an aerosol generating matrix, causing the matrix to atomize and form an aerosol. The aerosol formed from this atomized matrix can then be inhaled by a user.

[0003] Aerosol generating devices typically consist of a housing assembly and an atomizing core. The housing assembly has an atomizing chamber and an air inlet communicating with the atomizing chamber, with the atomizing core located inside the atomizing chamber. During operation, outside air enters the atomizing chamber through the air inlet, and the aerosol generating matrix inside the housing assembly is conducted to the atomizing core. Under the heating effect of the atomizing core, the atomized matrix forms an aerosol, which can then flow with the air in the atomizing chamber to the outside of the housing assembly, achieving the misting effect.

[0004] The atomization chamber and the air inlet are connected, which means that the aerosol generation matrix conducted to the atomization core may flow through the atomization chamber into the air inlet, and may leak through the air inlet. In other words, the aerosol generation device has a significant leakage risk.

[0005] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Utility Model Content

[0058] The following detailed description is provided in conjunction with specific accompanying drawings and embodiments:

[0059] Please refer to the following: Figures 1 to 3 ,in Figure 1 This is a perspective structural diagram of the aerosol generating apparatus 100 provided in some embodiments of this application. Figure 2 for Figure 1 A sectional view along AA, Figure 3 for Figure 2 Enlarged view at point B. The nozzle structure 10 provided in this embodiment is applied to an aerosol generating device 100, which includes a nozzle structure 10 and an atomizing core 20 disposed within the nozzle structure 10. The atomizing core 20 is a component used to heat up when energized, thereby heating and atomizing the aerosol generating matrix to form an aerosol.

[0060] Please refer to the following: Figures 2 to 4 And in conjunction with other accompanying figures. Figure 4This is a perspective view of the base 2 and sealing element of the aerosol generating device 100 provided in some embodiments of this application. The nozzle structure 10 provided in this application includes a first housing assembly 1, a base 2, and a bottom shell 3. The first housing assembly 1 has an atomizing chamber 101 inside, which is used to install the atomizing core 20. The base 2 is located at one end of the first housing assembly 1 along a first direction Y, and the base 2 has a through-hole air inlet channel 201, which communicates with the atomizing chamber 101. The inner wall of the air inlet channel 201 has a first groove 202, and the base 2 has a second groove 203 on the side along the first direction Y away from the atomizing chamber 101, which communicates with the first groove 202. At least a portion of the bottom shell 3 is located on the side of the base 2 along the first direction Y away from the atomizing chamber 101, to cover at least a portion of the second groove 203.

[0061] The first housing assembly 1 is the outer shell structure of the nozzle structure 10. Specifically, when the nozzle structure 10 is applied to the aerosol generating device 100, the first housing assembly 1 can be at least a part of the outer shell structure of the aerosol generating device 100.

[0062] The atomizing chamber 101 refers to the space used to install the atomizing core 20 and to allow the atomizing core 20 to heat and atomize the aerosol generating matrix to form an aerosol. Understandably, the interior of the first housing assembly 1 can also be used to store the aerosol generating matrix. The atomizing core 20 is disposed within the atomizing chamber 101, and the aerosol generating matrix can be conducted to the atomizing core 20. The atomizing core 20 heats the aerosol generating matrix, thereby heating and atomizing it within the atomizing chamber 101 to form an aerosol.

[0063] The first direction Y is the approximate orientation of the base 2 mounted on the first housing assembly 1, that is, the base 2 is located on one end of the first housing assembly 1 approximately along the first direction Y.

[0064] The air intake channel 201 can penetrate the base 2 along the first direction Y, or it can penetrate the base 2 along other directions, so that the air intake channel 201 connects the side of the base 2 away from the atomizing chamber 101 along the first direction Y to the atomizing chamber 101. As an example, such as Figure 2 and Figure 3 As shown, the air intake channel 201 passes through the base 2 along the first direction Y, that is, the air intake channel 201 passes through both sides of the base 2 along the first direction Y; and the air intake channel 201 and the atomizing chamber 101 are distributed along the first direction Y and are connected.

[0065] The first groove 202 and the second groove 203 are both groove structures provided on the base 2. The second groove 203 is provided on the side of the base 2 away from the atomizing chamber 101 along the first direction Y, and extends to the first groove 202, so that the first groove 202 and the second groove 203 are connected.

[0066] At least a portion of the bottom shell 3 is disposed on the side of the base 2 away from the atomizing chamber 101 along the first direction Y, so as to cover at least a portion of the second groove 203, such that the bottom shell 3 and the second groove 203 can enclose and form a space for accommodating the aerosol generation matrix. The bottom shell 3 can be mounted on the first housing assembly 1, or on the base 2, or on both the first housing assembly 1 and the base 2.

[0067] The nozzle structure 10 provided in this application embodiment has a first groove 202 on the inner side wall of the air intake channel 201. The base 2 has a second groove 203 connected to the first groove 202 on the side away from the atomizing chamber 101 along the first direction Y. At least a portion of the bottom shell 3 is located on the side of the base 2 away from the atomizing chamber 101 along the first direction Y, so as to cover at least a portion of the second groove 203. This allows the aerosol generating matrix in the atomizing chamber 101 to flow into the air intake channel 201, and the aerosol generating matrix can flow sequentially along the first groove 202 into the second groove 203 and flow along the second groove 203, thereby being stored in the space formed by the second groove 203 on the base 2 and the bottom shell 3. This can reduce the leakage of the aerosol generating matrix and improve the problem of aerosol generating matrix leakage. Specifically, it can improve the problem of aerosol generating matrix leaking outside the nozzle structure 10 through the air intake channel 201.

[0068] It should be further noted that the first housing assembly 1 may also be provided with a mist outlet channel 102, which is connected to the atomization chamber 101. When the aerosol generating device 100 is working, outside air can flow into the atomization chamber 101 through the air inlet channel 201. The aerosol generating matrix inside the first housing assembly 1 can be conducted to the atomizing core 20. The atomizing core 20 heats and atomizes the aerosol generating matrix to form an aerosol within the atomization chamber 101. This aerosol can flow with the air in the atomization chamber 101 to the mist outlet channel 102, and then flow out of the first housing assembly 1 through the mist outlet channel 102 to achieve the misting effect.

[0069] In some embodiments, please refer to Figure 4 And in conjunction with other accompanying drawings. The inner wall of the air intake passage 201 is provided with a plurality of first grooves 202, which are spaced apart circumferentially. Each first groove 202 is connected to a second groove 203.

[0070] Understandably, multiple first grooves 202 can extend into second grooves 203, allowing the aerosol generation matrix within each first groove 202 to flow into the second groove 203. As an example, such as... Figure 2 and Figure 3As shown, the air intake channel 201 passes through the base 2 along the first direction Y, that is, the air intake channel 201 passes through both sides of the base 2 along the first direction Y. Furthermore, each first groove 202 extends along the first direction Y and extends to the second groove 203.

[0071] This configuration allows the aerosol generation matrix in the air intake channel 201 to selectively flow through at least one of the multiple first grooves 202 to the second groove 203, facilitating the flow of the aerosol generation matrix in the air intake channel 201 along the first groove 202 to the second groove 203, and to be stored in the space formed by the second groove 203 and the bottom shell 3.

[0072] In some embodiments, please refer to Figure 4 And in conjunction with other accompanying drawings. The second groove 203 includes a first groove segment 2031 and a plurality of second groove segments 2032. The first groove segment 2031 extends into the first groove 202 to communicate with the first groove 202. The plurality of second groove segments 2032 are spaced apart. The first groove segment 2031 passes through the plurality of second groove segments 2032 to connect the plurality of second groove segments 2032.

[0073] Understandably, there can be at least one first slot segment 2031. When there is only one first slot segment 2031, the first slot segment 2031 passes through multiple second slot segments 2032 to connect the multiple second slot segments 2032; when there are multiple first slot segments 2031, each first slot segment 2031 passes through multiple second slot segments 2032 to connect the multiple second slot segments 2032.

[0074] This configuration allows the aerosol generation matrix to flow along the first groove 202 to the first groove section 2031, and then through the first groove section 2031 to multiple second groove sections 2032. This facilitates the storage of more aerosol generation matrix in the space formed by the bottom shell 3 and the second groove 203, thereby improving the problem of leakage of the aerosol generation matrix through the air intake channel 201.

[0075] It should be noted that when the inner wall of the air intake channel 201 is provided with multiple first grooves 202, the number of first groove segments 2031 is multiple, and each first groove 202 extends to the corresponding first groove segment 2031 to connect with the corresponding first groove segment 2031.

[0076] It should also be noted that the bottom shell 3 may cover at least a portion of the first groove segment 2031; may also cover at least a portion of the second groove segment 2032; and may also cover at least a portion of the first groove segment 2031 and at least a portion of the second groove segment 2032.

[0077] In some embodiments, please refer to Figure 4And in conjunction with other accompanying drawings. The second groove 203 includes a third groove segment 2033 and a plurality of second groove segments 2032. At least one second groove segment 2032 communicates with the first groove 202. The third groove segment 2033 surrounds the outer periphery of the plurality of second groove segments 2032 to communicate with the plurality of second groove segments 2032.

[0078] At least one second groove segment 2032 may extend directly to the first groove 202 to communicate with the first groove 202. A first groove segment 2031 may also be provided between at least one second groove segment 2032 and the first groove 202, so that the first groove 202 is connected to the second groove segment 2032 through the first groove segment 2031.

[0079] Among them, in the plurality of second slot segments 2032, both ends of each second slot segment 2032 extend to the third slot segment 2033, so that the third slot segment 2033 connects the plurality of second slot segments 2032.

[0080] The second slot segment 2032 involved in this embodiment can be the same as the second slot segment 2032 involved in the above embodiments, and will not be described again here.

[0081] The third groove 2033 surrounds the outer periphery of the multiple second grooves 2032, making the multiple second grooves 2032 interconnected. In this way, when the aerosol generating matrix in the air intake channel 201 flows along the first groove 202 to the second groove 203, it can flow to the multiple second grooves 2032 respectively. This allows the space formed by the bottom shell 3 and the second groove 203 to store more aerosol generating matrix, thereby improving the problem of aerosol generating matrix leakage through the air intake channel 201.

[0082] It should also be noted that the bottom shell 3 may cover at least a portion of the second groove segment 2032; may also cover at least a portion of the third groove segment 2033; and may also cover at least a portion of both the second groove segment 2032 and the third groove segment 2033.

[0083] In some embodiments, please refer to the following: Figures 2 to 4 And in conjunction with other accompanying drawings. The base 2 has an air intake chamber 2011 recessed along the first direction Y away from the atomizing chamber 101, and a first wall 206 disposed on the outer periphery of the air intake chamber 2011. A first air intake hole 2012 is provided through the air intake chamber 2011 along the first direction Y away from the first wall 206, and the first air intake hole 2012 communicates with the atomizing chamber 101. The air intake channel 201 includes the air intake chamber 2011 and the first air intake hole 2012. A first groove 202 is disposed on the inner wall of the air intake chamber 2011, and a second groove 203 is disposed on the first wall 206.

[0084] Understandably, the air intake chamber 2011 and the first air intake hole 2012 are distributed along the first direction Y and are connected, so that the air intake channel 201 passes through the base 2 along the first direction Y.

[0085] The air intake channel 201 is configured to include an air intake chamber 2011 and a first air intake through hole 2012, and a first groove 202 is disposed on the inner side wall of the air intake chamber 2011, which facilitates the formation of the first groove 202 on the inner side wall of the air intake channel 201, thereby facilitating the flow of the aerosol generation matrix in the air intake channel 201 along the first groove 202 and the second groove 203.

[0086] It should be noted that when the aerosol generating matrix flows into the first air inlet 2012, the aerosol generating matrix can flow sequentially along the first groove 202 and the second groove 203.

[0087] In some embodiments, please refer to Figure 4 And in conjunction with other accompanying drawings. A portion of the first groove 202 is located on the inner sidewall of the first air inlet hole 2012.

[0088] Understandably, the first groove 202 can extend from the inner wall of the first air inlet 2012 to the inner wall of the air intake chamber 2011. In this way, the aerosol generating matrix within the first air inlet 2012 can flow along the portion of the first groove 202 within the first air inlet 2012, then along the portion of the first groove 202 within the air intake chamber 2011, and then along the second groove 203, thereby being stored within the space formed by the second groove 203 and the bottom shell 3. This arrangement facilitates the flow of the aerosol generating matrix along the first groove 202 on the inner wall of the air intake channel 201 to the second groove 203, thereby facilitating the storage of the aerosol generating matrix and mitigating the problem of aerosol generating matrix leakage.

[0089] In some embodiments, please refer to the following: Figure 4 and Figure 5 And in conjunction with other accompanying figures. Figure 5 This is a perspective view of the base 2 of the aerosol generating device 100 provided in some embodiments of this application. The base 2 has an air inlet 21 protruding from the side away from the first wall 206 along the first direction Y. An air inlet cavity 2011 is disposed in the air inlet 21. The air inlet 21 has a first surface 204 on the side away from the first wall 206 along the first direction Y. A first air inlet hole 2012 penetrates the first surface 204 along the first direction Y, and the first surface 204 is an arc-shaped surface.

[0090] Understandably, the first air intake hole 2012 penetrates the side of the air intake cavity 2011 away from the first wall 206 along the first direction Y, and penetrates the first surface 204 of the air intake part 21 away from the first wall 206 along the first direction Y, so that the first air intake hole 2012 penetrates the air intake part 21 along the first direction Y.

[0091] By making the first surface 204 an arc-shaped surface, when the aerosol generating matrix in the atomizing chamber 101 flows toward the air inlet 21, it can flow along the first surface 204 of the air inlet 21 to the outer periphery of the air inlet 21, making it difficult for it to flow to the first air inlet hole 2012. This can improve the problem of the aerosol generating matrix flowing from the atomizing chamber 101 to the first air inlet hole 2012 and then flowing through the air inlet channel 201 to the outside of the nozzle structure 10, thus improving the problem of aerosol generating matrix leakage.

[0092] In some embodiments, please refer to Figure 5 Furthermore, in conjunction with other accompanying drawings, the first surface 204 is a spherical surface.

[0093] By setting the first surface 204 as a surface, the aerosol generation matrix on the first surface 204 can flow to the outer periphery of the air inlet 21, thereby improving the problem of the aerosol generation matrix flowing from the atomization chamber 101 to the first air inlet hole 2012 and then flowing to the outside of the nozzle structure 10 through the air inlet channel 201, and improving the problem of aerosol generation matrix leakage.

[0094] In some embodiments, please refer to Figure 4 In conjunction with other accompanying drawings, the nozzle structure 10 also includes a sealing element 4, which is disposed on the side of the base 2 away from the atomizing chamber 101 along the first direction Y, surrounds the outer periphery of the second groove 203, and abuts against the base 2 and the bottom shell 3.

[0095] The sealing element 4 can be a ring-shaped structure with sealing properties, such as a rubber ring or a silicone ring.

[0096] By having the sealing element 4 surround the outer periphery of the second groove 203 and abut against the base 2 and the bottom shell 3, the sealing performance of the space formed by the second groove 203 and the bottom shell 3 can be improved, thereby facilitating the storage of the aerosol generation matrix in the space formed by the second groove 203 and the bottom shell 3 and improving the problem of aerosol generation matrix leakage.

[0097] In some embodiments, please refer to the following: Figures 3 to 5 And in conjunction with other accompanying drawings. The base 2 has a through hole 205 extending along the first direction Y. The through hole 205 is used to install the pin 30. The through hole 205 is spaced apart from the air intake channel 201, the first groove 202, and the second groove 203.

[0098] Pin 30 is electrically connected to the atomizer core 20. Pin 30 is used to electrically connect to an external battery device 200, so that the atomizer core 20 and the battery device 200 are electrically connected.

[0099] By installing through holes 205 at intervals with the air intake channel 201, the first groove 202, and the second groove 203, the aerosol generation matrix in the first air intake through hole 2012 can avoid the installation through hole 205 when it flows along the first groove 202 and the second groove 203 in sequence, thereby avoiding the pin 30. This can improve the reliability of the electrical connection between the battery device 200 and the atomizing core 20.

[0100] Please refer to the following: Figures 1 to 3 The aerosol generating device 100 provided in this embodiment includes a nozzle structure 10 and an atomizing core 20, with the atomizing core 20 disposed within the atomizing chamber 101. The nozzle structure 10 in this embodiment is the same as that in the previous embodiments; please refer to the relevant descriptions of the nozzle structure 10 in the previous embodiments for details, which will not be repeated here.

[0101] The aerosol generating device 100 provided in this application embodiment, by adopting the nozzle structure 10 involved in the above embodiments, can reduce the leakage of the aerosol generating matrix and improve the problem of aerosol generating matrix leakage.

[0102] Please refer to the following: Figure 6 and Figure 7 And in conjunction with other accompanying figures. Figure 6 This is a three-dimensional structural diagram of an electronic atomizer provided in some embodiments of this application. Figure 7 for Figure 6 A three-dimensional structural diagram of the battery device 200 of the provided electronic atomizer. The electronic atomizer provided in this embodiment includes an aerosol generating device 100 and a battery device 200. The battery device 200 is mounted on the aerosol generating device 100 and electrically connected to the atomizing core 20. The aerosol generating device 100 in this embodiment is the same as the aerosol generating device 100 in the above embodiments; please refer to the relevant descriptions of the aerosol generating device 100 in the above embodiments for details, which will not be repeated here.

[0103] When the battery device 200 is installed on the aerosol generating device 100, the pins 30 on the aerosol generating device 100 and the terminals on the battery device 200 are connected to each other so that the battery device 200 and the atomizing core 20 are electrically connected.

[0104] As an example, the battery device 200 has a mounting cavity (not shown) at one end along the first direction Y, and at least a portion of the aerosol generating device 100 is mounted in the mounting cavity.

[0105] The electronic atomizer provided in this application, by employing the aerosol generation device 100 described in the above embodiments, can reduce the leakage of the aerosol generation matrix and improve the problem of aerosol generation matrix leakage. Specifically, it can reduce the flow of the aerosol generation matrix in the air intake channel 201 into the battery device 200, thereby reducing the problem of malfunction of the battery device 200 and electrical connection failure between the battery device 200 and the atomizing core 20.

[0106] In some embodiments, please refer to Figure 7 And in conjunction with other accompanying drawings. The battery device 200 includes a second housing assembly 210 and a battery assembly. The battery assembly is disposed within the second housing assembly 210 and electrically connected to the atomizing core 20. The second housing assembly 210 has a second air inlet 2001 and a third groove 2002 at one end along the first direction Y, the third groove 2002 surrounding the outer periphery of the second air inlet 2001. At least a portion of the air intake channel 201 is disposed opposite to and communicating with the third groove 2002 along the first direction Y, and the air intake channel 201 is offset from the second air inlet 2001.

[0107] The second housing assembly 210 is the outer casing structure of the battery device 200. The second air inlet 2001 is connected to the interior of the second housing assembly 210.

[0108] Understandably, the second housing assembly 210 is mounted on the aerosol generating device 100. Specifically, the second housing assembly 210 has the aforementioned mounting cavity at one end along the first direction Y, and the mounting cavity communicates with the second air inlet 2001 and the third groove 2002.

[0109] The air intake channel 201 and the second air intake hole 2001 are offset, meaning that on the projection plane perpendicular to the first direction Y, the orthographic projection of the air intake hole and the orthographic projection of the second air intake hole 2001 are offset and do not overlap.

[0110] The air intake channel 201 is configured to be opposite to and connected to the third groove 2002 along the first direction Y, and the air intake channel 201 is offset from the second air intake hole 2001. This ensures that even if the aerosol generation matrix in the air intake channel 201 flows to the battery device 200, it will preferentially flow to the third groove 2002 opposite to the air intake channel 201 and be stored in the third groove 2002, instead of flowing directly to the second air intake hole 2001. This can improve the problem that the aerosol generation matrix flows into the second housing assembly 210 through the second air intake hole 2001, causing damage to the function of the battery assembly.

[0111] At least a portion of the air intake channel 201 is disposed opposite to and connected to the third groove 2002 along the first direction Y. The third groove 2002 surrounds the outer periphery of the second air intake hole 2001, so that the air intake channel 201 can be connected to the second air intake hole 2001 through the third groove 2002.

[0112] The battery assembly may include a battery and a circuit board electrically connected to the battery, and the terminals may be disposed on the circuit board.

[0113] Understandably, the second housing assembly 210 may also be provided with a third air inlet 2003, which connects to the second air inlet 2001 through the internal space of the second housing assembly 210. Based on this, when the electronic atomizer is working, the battery assembly can power the atomizing core 20 to heat it. The aerosol generating matrix inside the first housing assembly 1 can be conducted to the atomizing core 20 and atomized into an aerosol under the heating action of the atomizing core 20. Outside air enters the second housing assembly 210 through the third air inlet 2003 and flows sequentially through the second air inlet 2001 and the air intake channel 201 into the atomization chamber 101. The aerosol flows out of the first housing assembly 1 with the air in the atomization chamber 101, thus achieving the atomization effect.

[0114] In some embodiments, please refer to Figure 7 Furthermore, in conjunction with other accompanying drawings, a portion of the second groove 203 is exposed outside the bottom shell 3, and the exposed portion of the second groove 203 is offset from the second air inlet 2001.

[0115] By offsetting the portion of the second groove 203 exposed outside the bottom shell 3 from the second air inlet 2001, the problem of aerosol generation matrix flowing into the second groove 203 falling into the second air inlet 2001 can be improved, thereby improving the problem of power supply performance failure of the battery device 200.

[0116] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
