[0028] Please see Figures 1-5 , Figure 1 A schematic diagram of the structure of an atomizer 100 provided in some embodiments of this application (push rod assembly 10 blocks the communication hole 28). Figure 2 for Figure 1 The cross-sectional view of the atomizer 100 provided in the document. Figure 3 This is a schematic diagram of the structure of an atomizer 100 provided in some embodiments of this application (the push rod assembly 10 has not blocked the connecting hole 28). Figure 4 for Figure 3 The cross-sectional view of the atomizer 100 provided in the document. Figure 5 for Figure 4 A magnified view of a portion of point A in the middle.

[0029] The atomizer 100 provided in this embodiment includes an atomizer body 20, an atomizer core 30, and a push rod assembly 10. Please refer to [link to relevant documentation]. Figure 1 and Figure 3 The atomizer body 20 is shown in the diagram. Please refer to [link / reference]. Figure 2 and Figure 4 The atomizing core 30 is installed inside the atomizer body 20, and one end of the push rod assembly 10 is inserted into the atomizer body 20.

[0030] Please see Figure 2 and Figure 4 The atomizer body 20 has a first cavity 26, a second cavity 27 and a connecting hole 28 connecting the first cavity 26 and the second cavity 27. The first cavity 26 is used to store the aerosol matrix, and the aerosol matrix in the second cavity 27 can flow to the atomizing core 30.

[0031] Please see Figure 2 One end of the push rod assembly 10 is inserted into the connecting hole 28, and the push rod assembly 10 and the connecting hole 28 are sealed together to prevent the aerosol matrix in the first chamber 26 from flowing to the second chamber 27 through the connecting hole 28. This is the state of the atomizer 100 after it leaves the factory and is not used by the user; please refer to Figure 4 At this time, the push rod assembly 10 does not block the connecting hole 28. This can be understood as the push rod assembly 10 being able to slide relative to the atomizer body 20 when force is applied. When the push rod assembly 10 is moved from... Figure 2 Push the indicated position inwards as shown Figure 4 At the position shown, the aerosol matrix within the first cavity 26 can move along... Figure 4 As indicated by the middle arrow, the fluid flows out through the gap between the push rod assembly 10 and the connecting hole 28, and flows into the second cavity 27.

[0032] Specifically, please see Figure 2 The push rod assembly 10 provided in this embodiment includes a sealing end 14 and a main body 15. The sealing end 14 is disposed at one end of the main body 15 and is used for sealing engagement with the connecting hole 28. Please refer to... Figure 4 The main body 15 also includes a conductive section 151, one end of which is connected to the sealing end 14. The cross-sectional area of ​​the conductive section 151 is smaller than that of the connecting hole 28. When the push rod assembly 10 needs to block the connecting hole 28, the sealing end 14 is placed in the connecting hole 28. When the first cavity 26 and the second cavity 27 need to be connected, the push rod assembly 10 is pushed so that the conductive section 151 is inserted into the connecting hole 28. Since the cross-sectional area of ​​the conductive section 151 is smaller than that of the connecting hole 28, a fluid-guiding gap is formed between the push rod assembly 10 and the connecting hole 28.

[0033] Because the aerosol matrix in the first chamber 26 flows out relatively slowly through the gap between the conductive section 151 and the connecting hole 28, and because the second chamber 27 has a relatively large volume, when the user inhales from the atomizer 100, the insufficient liquid inlet rate of the atomizing core 30 can lead to problems such as dry burning and a bitter taste during inhalation. To minimize these problems, please refer to the embodiments in this application. Figure 4 A liquid guiding structure 16 is formed on the main body 15, which is used to directly guide the aerosol matrix to the atomizing core 30.

[0034] Please see Figure 4 The atomizer body 20 is provided with a mating hole 29. When the push rod assembly 10 is in the position shown in the image, the mating hole 29 is provided. Figure 4 As shown in the diagram, when the first cavity 26 and the second cavity 27 are in a conductive state, the mating hole 29 can avoid the liquid guiding structure 16, allowing the aerosol matrix in the first cavity 26 to flow directly to the atomizing core 30 through the liquid guiding structure 16; of course, one end of the liquid guiding structure 16 can also be connected to the mating hole 29, allowing the aerosol matrix in the first cavity 26 to flow directly to the atomizing core 30 through the liquid guiding structure 16 and the mating hole 29.

[0035] In this embodiment, at least one liquid guiding structure 16 is formed on the main body 15. That is, one liquid guiding structure 16 or two or more liquid guiding structures 16 can be provided on the main body 15. Each liquid guiding structure 16 can guide the aerosol matrix in the first cavity 26 to the atomizing core 30.

[0036] In some examples, the liquid guiding structure 16 can be set as a liquid guiding through hole on the main body 15; in other examples, please refer to [link to relevant documentation]. Figure 5 The liquid guiding structure 16 can be configured as a liquid guiding groove on the outer side of the main body 15. The following description mainly uses the example of the liquid guiding structure 16 being a liquid guiding groove on the outer side of the main body 15 to further describe the push rod assembly 10.

[0037] It should be noted that when the liquid guiding structure 16 is a liquid guiding groove provided on the outer side of the main body 15, please refer to [the relevant documentation]. Figure 5 A liquid guiding structure 16 can be set to form a liquid guiding channel with the wall surface of the connecting hole 28 and the wall surface of the connecting hole 29, so as to facilitate the flow of the aerosol matrix to the atomizing core 30.

[0038] In this embodiment, by providing a liquid guiding structure 16 on the push rod assembly 10, the aerosol matrix in the first cavity 26 can not only flow out through the gap between the conductive section 151 and the connecting hole 28 on the push rod assembly 10, but also flow out of the first cavity 26 through the liquid guiding structure 16, thereby improving the flow rate of the aerosol matrix. In addition, by providing a liquid guiding structure 16 on the push rod assembly 10, the atomizing core 30 can directly adsorb the aerosol matrix flowing from the liquid guiding structure 16, which can effectively reduce problems such as dry burning and bitter taste during user inhalation due to insufficient liquid supply.

[0039] It should be noted that the size of the cross-section of the liquid guiding structure 16 can be reasonably set so that when large air bubbles in the aerosol matrix in the first cavity 26 flow into the liquid guiding structure 16, the groove wall of the liquid guiding structure 16 can puncture the air bubbles, reducing the problem of air bubbles being stuck (the problem of air bubbles being stuck refers to the problem that air bubbles are blocked in the gap between the liquid guiding structure 16 and the push rod assembly 10 and the connecting hole 28, making it difficult for the aerosol matrix in the first cavity 26 to flow into the second cavity 27).

[0040] In some embodiments, see Figure 5 The liquid guiding structure 16 is a liquid guiding groove disposed on the outer side of the main body 15. The liquid guiding structure 16 includes a first groove segment 161 and a second groove segment 162. One end of the second groove segment 162 is connected to the first groove segment 161. The extension direction of the first groove segment 161 is along the length direction of the push rod assembly 10, and the extension direction of the second groove segment 162 is along the radial direction of the push rod assembly 10. The end of the second groove segment 162 facing away from the push rod assembly 10 faces the atomizing core 30. When the first cavity 26 and the second cavity 27 are in a conductive state, the aerosol matrix in the first cavity 26 can flow through the first groove segment 161 to the second groove segment 162, and then through the second groove segment 162 to the atomizing core 30.

[0041] In some examples, the cross-section of the first groove segment 161 can be set to be rectangular, trapezoidal, or arc-shaped, and the cross-section of the second groove segment 162 can be set to be rectangular, trapezoidal, or arc-shaped.

[0042] In this embodiment of the application, the liquid guiding structure 16 is defined to include a first groove segment 161 and a second groove segment 162, so as to guide the aerosol matrix in the first cavity 26 to the atomizing core 30 through the liquid guiding structure 16.

[0043] Please see Figures 6-8 , Figure 6 This is an exploded schematic diagram of the atomizer 100 provided in some embodiments of this application. Figure 7 This is a schematic diagram of the structure of the bracket 22 provided in some embodiments of this application. Figure 8 This is a cross-sectional schematic diagram of the compartment 21 provided in some embodiments of this application.

[0044] In some embodiments, see Figure 6 The atomizer body 20 includes a chamber 21, a support 22, and a base 23. Please refer to [link / reference]. Figure 2 The bracket 22 is installed inside the chamber 21 and is sealed to the chamber 21. Please refer to [link / reference]. Figure 2 An air intake channel 214 is formed on the chamber 21. The base 23 is set on the side of the bracket 22 away from the air intake channel 214. The atomizing core 30 is installed on the bracket 22 and the interior of the atomizing core 30 is connected to the air intake channel 214. The push rod assembly 10 passes through the base 23 and is inserted into the bracket 22.

[0045] See some examples. Figure 2 The chamber 21 includes a main body 211 and an air guide cylinder 212. The air guide cylinder 212 is disposed inside the main body 211. A suction nozzle 213 is formed at one end of the main body 211. The interior of the air guide cylinder 212 is connected to the suction nozzle 213, and the interior of the air guide cylinder 212 and the suction nozzle 213 form an air intake channel 214 for the chamber 21. Please refer to [link / reference]. Figure 6 The atomizer body 20 also includes a first seal 24, see [link to documentation]. Figure 2 One end of the bracket 22 is sealed to the air guide cylinder 212 through the first sealing element 24, and the chamber 21, the bracket 22 and the first sealing element 24 form a first cavity 26.

[0046] See some examples. Figure 7 The bracket 22 has a second mounting channel 222 formed inside, and the atomizing core 30 is used to insert into the second mounting channel 222. Please refer to [link / reference]. Figure 6 and Figure 7The bracket 22 is also provided with a liquid inlet 210, which is used to connect the second installation channel 222 and the second cavity 27. The aerosol matrix in the second cavity 27 can flow to the atomizing core 30 in the second installation channel 222 through the liquid inlet 210.

[0047] The atomizing core 30 includes a heating element, which can be a heating wire or a heating mesh. The heating element generates heat when an electric current flows through it, meaning the atomizing core 30 heats the aerosol matrix that has penetrated it, causing it to evaporate. When the user inhales through the mouthpiece 213 on the chamber 21, creating airflow within the atomizing core 30, the evaporated aerosol matrix condenses under the influence of the airflow, forming mist. This mist then flows with the airflow to the mouthpiece 213. In some examples, the atomizing core 30 includes an outer cotton layer, a support layer, an inner cotton layer, and a heating element. The inner cotton layer, support layer, and outer cotton layer are sequentially arranged from the inside out, with the heating element located inside the inner cotton layer.

[0048] See some examples. Figure 7 and Figure 8 A first mounting channel 221 is formed within the bracket 22. The first mounting channel 221 is arranged side-by-side on one side of the second mounting channel 222. The push rod assembly 10 is inserted into the first mounting channel 221. For details, please refer to... Figure 8 The first installation channel 221 includes a first channel segment 2211, a second channel segment 2212, and a third channel segment 2213, which are arranged sequentially. The first channel segment 2211 forms a connecting hole 28, the second channel segment 2212 is connected to the second cavity 27, and the third channel segment 2213 is connected to the second cavity 27. Figure 2 The second seal 25 is sealed to the push rod assembly 10.

[0049] See some examples. Figure 7 The support 22 includes a support cylinder portion 223, a first support portion 224, a second support portion 225, and a support connecting portion 226. The first support portion 224 and the second support portion 225 are sleeved on the support cylinder portion 223 and are spaced apart. The support connecting portion 226 connects the first support portion 224 and the second support portion 225. A second installation channel 222 is formed inside the support cylinder portion 223. An inlet 210 and a mating hole 29 are provided on the support cylinder portion 223. The space located on the outside of the support cylinder portion 223, the inside of the chamber 21, and between the first support portion 224 and the second support portion 225 is used to form a second cavity 27.

[0050] See some examples. Figure 4The base 23 is provided with a base socket 231 for inserting the push rod assembly 10, and an electrode 40 for connecting with the atomizing core 30 is provided on the base 23. An absorbent cotton 50 is also provided on the inner side of the base 23.

[0051] In some embodiments, see Figure 7 An abutment plate 227 is formed on the atomizer body 20. Please refer to [link / reference]. Figure 5 When the first cavity 26 and the second cavity 27 are in a conductive state through the connecting hole 28, the sealing end 14 contacts the abutment plate 227.

[0052] See some examples. Figure 7 The abutment plate 227 is disposed on the bracket cylinder 223 of the atomizer body 20, and the abutment plate 227 can be integrally formed on the bracket cylinder 223.

[0053] In this embodiment, by forming an abutment plate 227 on the atomizer body 20, the end of the push rod assembly 10 can contact the abutment plate 227 to limit the push rod assembly 10 from continuing to move into the atomizer body 20, thus limiting the push rod assembly 10.

The sealing portion 121 is used for sealing engagement with the connecting hole 28, and a liquid guiding structure 16 is formed on the guide portion 122. In the embodiment of this application, the sealing portion 121 is used to form the sealing end 14 of the push rod assembly 10. Please refer to [link to relevant documentation]. Figure 12 This illustrates the sealing fit between the sealing part 121 and the connecting hole 28.

[0061] In some examples, the sealing part 121 and the guide part 122 may be configured as an integral structure.

[0062] In some examples, in the sealing part 121 and the guide part 122, only the sealing part 121 may be fixedly connected to the support member 11, or both the sealing part 121 and the guide part 122 may be fixedly connected to the support member 11.

[0063] In this embodiment, the elastic member 12 is provided with a sealing portion 121 and a guiding portion 122 so that the liquid guiding structure 16 is formed on the elastic member 12.

[0064] It should be noted that the above embodiment describes the elastic element 12 as including a sealing portion 121 and a guiding portion 122. In other embodiments, the elastic element 12 may only include the sealing portion 121, that is, the elastic element 12 may not include the guiding portion 122, and the liquid guiding structure 16 may be disposed on the support member 11. Please refer to [link to relevant documentation]. Figure 11 The diagram illustrates that the fluid guiding structure 16 is mounted on the support member 11.

[0065] In some embodiments, see Figure 10The guide portion 122 includes a first guide section 1221 and a second guide section 1222. One end of the first guide section 1221 is connected to the sealing portion 121, and the other end of the first guide section 1221 is connected to the second guide section 1222. The second guide section 1222 extends away from the support member 11. The first guide section 1221 and the section on the support member 11 directly opposite the first guide section 1221 form the conducting section 151 of the push rod assembly 10. Please refer to [link to relevant documentation]. Figure 14 The diagram illustrates the first guide segment 1221 and the section insertion and connecting hole 28 on the support member 11 that is directly opposite the first guide segment 1221.

[0066] Please see Figure 10 The liquid guiding structure 16 is disposed on the first guide section 1221 and the second guide section 1222, and one end of the liquid guiding structure 16 opens to the end of the second guide section 1222 opposite to the first guide section 1221. Please refer to [link / reference]. Figure 10 When the liquid guiding structure 16 includes a first groove segment 161 and a second groove segment 162, the first guide segment 1221 is provided with the first groove segment 161, and the second guide segment 1222 is provided with the second groove segment 162.

[0067] See some examples. Figure 10 The first guide segment 1221 and the second guide segment 1222 can be set to be L-shaped.

[0068] Please see Figure 5 The second guide segment 1222 is inserted into the mating hole 29. In some examples, the end of the second guide segment 1222 that is away from the first guide segment 1221 abuts against the atomizing core 30; or, in other examples, there is a gap between the end of the second guide segment 1222 that is away from the first guide segment 1221 and the atomizing core 30.

[0069] It should be noted that when the push rod assembly 10 blocks the connecting hole 28, the second guide section 1222 is not inserted into the mating hole 29, and the channel wall of the first mounting channel 221 presses against the second guide section 1222, causing the second guide section 1222 to undergo elastic deformation; when the push rod assembly 10 is pushed to connect the first cavity 26 and the second cavity 27 through the connecting hole 28, the second guide section 1222 extends in the reset direction so that the free end of the second guide section 1222 can be inserted into the mating hole 29.

[0070] In this embodiment of the application, the guide portion 122 is provided to include a first guide segment 1221 and a second guide segment 1222, so as to provide a liquid guiding structure 16 in the guide portion 122.

[0071] In some embodiments, when the push rod assembly 10 is in the state of having the communication hole 28 open, the hole wall of the communication hole 28 is in contact with the side of the push rod assembly 10 on the side where the liquid guiding structure 16 is provided.

[0072] Please see Figure 5 The connecting hole 28 includes a first hole wall 281, a first guide section 1221 that fits into the first hole wall 281, and a first groove section 161 provided on the side of the first guide section 1221 facing the first hole wall 281.

[0073] In some examples, while the first guide segment 1221 conforms to the wall surface 281 of the first hole, the second guide segment 1222 conforms to the upper hole wall surface 291 of the mating hole 29. Please refer to [link / reference]. Figure 5 The diagram shows the upper hole wall 291 of the mating hole 29, and the second guide section 1222 is provided with a second groove section 162 on the side facing the upper hole wall 291.

[0074] In this embodiment, the wall surface of the connecting hole 28 is in contact with the surface of the push rod assembly 10 on the side where the liquid guiding structure 16 is provided, so as to facilitate the aerosol matrix of the first cavity 26 to the atomizing core 30 through the liquid guiding structure 16.

[0075] In some embodiments, see Figure 8 A guide groove 2214 is formed on the channel wall of the first installation channel 221. One end of the guide groove 2214 is connected to the mating hole 29. The guide groove 2214 is used to cooperate with the elastic element 12 of the push rod assembly 10 to guide the movement of the push rod assembly 10.

[0076] Please see Figure 10 The elastic element 12 includes a first guide section 1221 and a second guide section 1222. When the push rod assembly 10 blocks the connecting hole 28, the free end of the second guide section 1222 is inserted into the guide groove 2214 and abuts against the groove wall of the guide groove 2214. When the push rod assembly 10 is pushed in the direction of extending into the atomizer 100, the second guide section 1222 moves in the guide groove 2214 until the push rod assembly 10 moves into place and the second guide section 1222 is inserted into the mating hole 29.

[0077] In this embodiment of the application, by providing a guide groove 2214 on the channel wall of the first installation channel 221, not only can the movement of the second guide segment 1222 be guided, but also the deformation of the second guide segment 1222 when it is squeezed by the bracket 22 can be minimized.

[0078] When the elastic element 12 includes a sealing portion 121 and a guide portion 122, in some embodiments, please refer to Figure 10 The support member 11 includes a support member main body section 111 and a support member insertion section 112. The support member insertion section 112 is disposed at one end of the support member main body section 111 and the two are connected. The support member insertion section 112 is inserted into the sealing part 121. The support member insertion section 112 and the sealing part 121 are used to form the sealing end 14 of the push rod assembly 10.

[0079] In some examples, the sealing part 121 may be tightly fitted onto the support insertion section 112, or the sealing part 121 may be pasted onto the support insertion section 112; or the sealing part 121 may be integrally formed onto the support insertion section 112.

[0080] In this embodiment, the support member insertion section 112 is inserted into the sealing part 121 to facilitate a stable connection between the support member 11 and the sealing part 121.

[0081] In some embodiments, see Figure 10 The support member 11 also includes a limiting plate 113, which is disposed on the circumferential outer surface of the main body section 111 of the support member, and the limiting plate 113 contacts the end face of the sealing part 121. Please refer to Figure 10 A relief groove 1131 is formed on the limiting plate 113, and the guide part 122 passes through the relief groove 1131 and connects to the end face of the sealing part 121.

[0082] In this embodiment, the support member 11 is further provided with a limiting plate 113 to facilitate the positioning and installation of the elastic member 12 on the support member 11; and an avoidance groove 1131 is formed on the limiting plate 113 to facilitate the first guide segment 1221 of the guide portion 122 to fit into the main body segment 111 of the support member.

[0083] The above embodiment describes the elastic member 12 including a sealing portion 121 and a guiding portion 122, with the liquid guiding structure 16 disposed on the guiding portion 122. For other embodiments, please refer to... Figure 11 The liquid guiding structure 16 is provided on the support member 11, that is, the support member 11 includes a support body 114 and an extension section 115. The extension section 115 is provided on the circumferential side of the support body 114. An elastic member 12 is provided at one end of the support body 114. The support body 114 and the extension section 115 are respectively provided with a first groove section 161 and a second groove section 162. When the push rod assembly 10 is in the state of opening the connecting hole 28, the second groove section 162 on the extension section 115 is connected to the mating hole 29, so that the aerosol matrix in the first cavity 26 flows to the atomizing core 30 through the first groove section 161, the second groove section 162 and the mating hole 29.

[0084] In some embodiments, see Figure 10 The push rod assembly 10 also includes an anti-accidental contact sleeve 13, which is fitted onto the end of the support member 11 that is away from the elastic member 12.

[0085] Please see Figure 2A section of the support member 11 is located outside the atomizer 100. The anti-accidental contact sleeve 13 is fitted on the section of the support member 11 located outside the atomizer 100. The outer diameter of the anti-accidental contact sleeve 13 is larger than the diameter of the base insertion hole 231 on the base 23. The anti-accidental contact sleeve 13 is in contact with the base 23 of the atomizer 100. By setting the anti-accidental contact sleeve 13 on the support member 11, the push rod assembly 10 is prevented from being accidentally touched and thus extending into the atomizer 100. That is, when it is necessary to move the support member 11 into the atomizer 100, the anti-accidental contact sleeve 13 can be removed from the support member 11. When the support member 11 is moved to be fully inserted into the atomizer 100, the elastic element 12 of the push rod assembly 10 is not blocked from the connecting hole 28, and the first cavity 26 and the second cavity 27 can be connected through the connecting hole 28.

[0086] It should be noted that the above embodiment describes that the push rod assembly 10 also includes an anti-accidental contact sleeve 13. In other embodiments, the push rod assembly 10 may also be configured not to include the anti-accidental contact sleeve 13. When the sealing end 14 of the push rod assembly 10 blocks the connecting hole 28, the support member 11 is completely located inside the atomizer 100. When it is necessary to push the support member 11, an external tool can be used to insert the tool into the base insertion hole 231 on the base 23, so that the tool can push the support member 11 to move, so that the push rod assembly 10 moves to the state where the elastic member 12 does not block the connecting hole 28.

[0087] This application provides an atomizing device, including a battery rod and an atomizer 100 provided in any of the above embodiments. The atomizer 100 is disposed at one end of the battery rod and the two are connected.

[0088] The details of the atomizer 100 have been described above and will not be repeated here. The battery rod contains a battery and a circuit board. The battery rod provides the necessary power to the atomizer through the built-in battery so that it can work normally. The circuit board inside the battery rod is electrically connected to the electrode 40 inside the atomizer 100. The working state of the atomizer core 30 can be controlled through the circuit board.

[0089] 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.
