To ensure proper operation of the atomizing core, it is directly connected to the reservoir chamber, typically by immersing the core in it. An opening is provided on the outside of the core, allowing the aerosol matrix from the reservoir chamber to enter the core via capillary action. However, this process may result in excessive aerosol matrix entering the core, causing leakage of the liquid aerosol matrix from the inlet or outlet of the electronic atomizing device, which can be quite inconvenient for users.

[0007] When the atomizing device is configured to be stored upside down, the liquid level of the aerosol matrix is ​​equal to or lower than the interface between the liquid guiding chamber and the liquid storage chamber.

[0008] In one embodiment, the housing assembly includes a housing body, an air guide tube, and an end cap; the housing body is provided with an air inlet and an air outlet at the first end and the second end, respectively; the air guide tube is disposed inside the housing body and connects the air inlet and the air outlet to form an atomization channel; the air guide tube, the end cap, and the housing body enclose the liquid storage chamber, the end cap and the air guide tube enclose the liquid guiding chamber, and the end cap has an end face facing the housing body, the end face forming the interface.

[0009] In one embodiment, the atomizing component is provided with a plurality of liquid inlets, which are located in the liquid guiding chamber and are used to guide the aerosol matrix into the interior of the atomizing component.

[0010] In one embodiment, the area of ​​the liquid storage chamber along a cross-section perpendicular to the axial direction is greater than the area of ​​the liquid guiding chamber along a cross-section perpendicular to the axial direction.

[0011] In one embodiment, the end face is formed with a recessed groove, and the air guide tube is inserted into the groove; the end face, the inner wall of the shell body and the outer wall of the air guide tube enclose the liquid storage chamber, and the groove wall of the groove and the outer wall of the air guide tube enclose the liquid guiding chamber.

[0012] In one embodiment, the end cap is provided with a plurality of flanges at the opening of the settling tank, the plurality of flanges are spaced apart, and a liquid guiding hole is formed between adjacent flanges to connect the liquid storage chamber and the liquid guiding chamber.

[0013] In one embodiment, the cross-sectional area of ​​the liquid guiding hole is 2 mm. 2 ~5mm 2 .

[0014] In one embodiment, the end cap has an injection channel and an on / off valve corresponding to the injection channel; the injection channel is connected to the liquid storage chamber for injecting the aerosol matrix from the outside into the liquid storage chamber, and the on / off valve is used to control the injection channel to close or open.

[0035] In related technologies, to generate aerosols by heating the aerosol matrix through an atomizing component, the atomizing component is typically placed in a liquid storage chamber containing the aerosol matrix. The aerosol matrix enters the atomizing component via capillary action, and then the atomizing component heats the aerosol matrix to generate aerosols. However, if the amount of aerosol matrix accumulating in the atomizing component is too large, excess aerosol matrix will leak from the inlet or outlet of the atomizing device. This leakage may occur inside the atomizing device or directly outside, resulting in a poor user experience.

[0036] To improve the above-mentioned problems and avoid or reduce leakage of the aerosol matrix in the atomizing device, this application provides an atomizing device, please refer to... Figure 1 and Figure 2The atomizing device includes:

[0037] The housing assembly 1 has a first end 11 and a second end 12 facing each other. Inside the housing assembly 1 are formed an atomizing channel 13, a liquid storage chamber 14, and a liquid guiding chamber 15. The atomizing channel 13 extends from the first end 11 toward the second end 12 of the housing assembly 1. The liquid storage chamber 14 and the liquid guiding chamber 15 are arranged parallel to each other in the axial direction of the atomizing channel 13 and are connected. The atomizing channel 13 and the liquid guiding chamber 15 are connected to each other in the radial direction of the atomizing channel 13. The liquid storage chamber 14 is used to store the aerosol matrix, and the liquid guiding chamber 15 is used to guide the aerosol matrix into the atomizing channel 13.

[0038] Atomizing component 2 is disposed within atomizing channel 13; atomizing component 2 is connected to liquid guiding chamber 15 for heating aerosol matrix to form aerosol; and when the atomizing device is configured to be stored upside down, the liquid level of the aerosol matrix is ​​equal to or lower than the interface between liquid guiding chamber 15 and liquid storage chamber 14.

[0039] In this embodiment, the atomizing device is used to heat the aerosol matrix to generate an aerosol. To achieve the above objective, the atomizing device in this embodiment has a housing assembly 1 and an atomizing assembly 2, wherein the housing assembly 1 is used to form a chamber for storing the aerosol matrix, and the atomizing assembly 2 is used to heat the aerosol matrix to generate an aerosol.

[0040] To store the aerosol matrix, a liquid storage chamber 14 is formed inside the shell assembly 1, where the liquid aerosol matrix is ​​stored. To accommodate the atomizing component 2 and to allow the atomizing component 2 to heat the aerosol matrix, an atomizing channel 13 is also formed inside the shell assembly 1. The atomizing channel 13 and the liquid storage chamber 14 are not directly connected, but rather are relatively isolated. In this relatively isolated state, the aerosol matrix in the liquid storage chamber 14 does not directly enter the atomizing channel 13.

[0041] The atomizing component 2 can heat the incoming aerosol matrix to generate aerosol. In order to slow down the speed at which the aerosol matrix enters the atomizing component 2 and prevent excessive aerosol matrix from entering the atomizing component 2 and causing leakage of the aerosol matrix, the atomizing device in this embodiment of the application also has a liquid guiding chamber 15, wherein the liquid guiding chamber 15 is connected between the liquid storage chamber 14 and the atomizing channel 13. This means that the aerosol matrix in the liquid storage chamber 14 needs to pass through the liquid guiding chamber 15 before entering the atomizing channel 13.

[0042] The atomizing channel 13 is used to place the atomizing component 2, which is specifically placed at the connection between the atomizing channel 13 and the liquid guiding chamber 15. This allows the atomizing component 2 to directly receive the aerosol matrix entering from the connection, preventing the aerosol matrix from flowing into other locations and causing leakage or waste.

[0043] Specifically, the connection between the liquid storage chamber 14, the liquid guiding chamber 15, and the atomizing channel 13 is as follows: the liquid storage chamber 14 and the liquid guiding chamber 15 are arranged in parallel and connected along the extension direction of the atomizing channel 13—that is, along the axial direction of the atomizing channel 13. This means that the liquid storage chamber 14 and the liquid guiding chamber 15 are arranged vertically along the extension direction of the atomizing channel 13. This allows the aerosol matrix in the liquid storage chamber 14 to enter the liquid guiding chamber 15 under the action of gravity. The atomizing channel 13 is not directly connected to the liquid storage chamber 14, but is connected to the liquid guiding chamber 15 radially. This means that only the aerosol matrix in the liquid guiding chamber 15 can enter the atomizing channel 13 through the connection with the atomizing channel 13. Therefore, in this embodiment, the aerosol matrix in the storage chamber 14 enters the atomization channel 13 only after passing through the storage chamber 14 and the guiding chamber 15 in sequence. Compared to directly immersing the atomization component 2 in the storage chamber 14, this effectively slows down the speed at which the aerosol matrix enters the atomization component 2 from the storage chamber. Furthermore, by configuring the storage chamber 14 and the guiding chamber 15 to be arranged in parallel and connected along the extension direction of the atomization channel 13, the aerosol matrix moves vertically between the storage chamber 14 and the guiding chamber 15. The guiding chamber 15 is radially connected to the atomization channel 13, allowing the aerosol matrix to move horizontally between them. Since the aerosol matrix needs to move in two different directions from the storage chamber 14 into the atomization channel 13, this further reduces the speed at which the aerosol matrix enters the atomization channel 13, thereby further reducing the possibility of aerosol matrix leakage.

[0044] The atomizing device is typically transported upside down, meaning its spatial orientation is reversed from when it is inhaled by the user. When inhaled, the second end 12 of the atomizing device is positioned upwards and the first end 11 downwards, with the user inhaling through the outlet at the second end 12. However, during transport, the atomizing device is positioned with the first end 11 upwards and the second end 12 downwards. This allows the aerosol matrix, originally located in the liquid guiding chamber 15, to pass through the liquid guiding chamber 15 and the liquid storage chamber 14 under gravity. The liquid flows back into the storage chamber 14 through the connection between the liquid guiding chamber 15 and the storage chamber 14. At this time, the liquid level of the aerosol matrix is ​​equal to or lower than the interface between the liquid guiding chamber 15 and the storage chamber 14. Since the atomizing component 2 is connected to the liquid guiding chamber 15, and the liquid level of the aerosol matrix is ​​equal to or lower than the interface, the possibility of the aerosol matrix entering the atomizing component 2 through the liquid guiding chamber 15 is basically eliminated when the atomizing device is stored upside down. This effectively prevents the aerosol matrix from leaking from the atomizing component 2.

[0045] In some alternative embodiments, please refer to Figure 2 To form the chambers in this embodiment within the housing assembly 1, the housing assembly 1 includes a housing body 3, an air guide pipe 4, and an end cap 5. The housing body 3 has an air inlet and an air outlet at a first end 11 and a second end 12, respectively. The air guide pipe 4 is disposed inside the housing body 3 and connects the air inlet and the air outlet to form an atomization channel 13. The air guide pipe 4, the end cap 5, and the housing body 3 enclose a liquid storage chamber 14, and the end cap 5 and the air guide pipe 4 enclose a liquid guiding chamber 15. The end cap 5 has an end face 51 facing the housing body, and the end face 51 forms an interface. The housing body 3 can be integrally formed or a structure formed by splicing two or more parts. The housing body 3 has multiple housing walls, and each housing wall encloses a space with an opening. The end cap 5 is disposed at the opening of the housing body 3, which can seal the opening formed by the housing body 3, and encloses a relatively sealed space with each housing wall of the housing body 3. The space is further divided into different components according to the positions of the shell body 3, the air guide tube 4, and the end cap 5. The two ends of the air guide tube 4 are connected to the air inlet and air outlet of the shell body 3, and an atomization channel 13 is formed inside the air guide tube 4. The atomization channel 13 is used to accommodate the atomization component 2. The shell body 3, the air guide tube 4, and the end cap 5 together form a liquid storage chamber 14. At this time, the liquid storage chamber 14 is not directly connected to the atomization channel 13. The end cap 5 and the air guide tube 4 form a liquid guiding chamber 15. At this time, the liquid guiding chamber 15 is directly connected to the atomization channel 13, and the liquid guiding chamber 15 is also connected to the liquid storage chamber 14 through the end cap 5.

[0046] In some optional embodiments, to ensure liquid connection between the atomizing component 2 and the liquid guiding chamber 15, the atomizing component 2 is provided with several liquid inlets 20, which are located within the liquid guiding chamber 15 and are used to guide the aerosol matrix into the interior of the atomizing component 2. Since the liquid inlets 20 are located within the liquid guiding chamber 15, when the aerosol matrix is ​​present in the liquid guiding chamber 15, the aerosol matrix can enter the atomizing component 2 through the liquid inlets 20; however, when there is no aerosol matrix in the liquid guiding chamber 15, including when the atomizing device is in an inverted state, no aerosol matrix will enter the atomizing component 2, thereby preventing leakage of the aerosol matrix.

[0047] In some alternative embodiments, to further slow the flow rate of the aerosol matrix into the atomization channel 13, the area of ​​the liquid storage chamber 14 along its cross-section perpendicular to the axial direction can be configured to be larger than the area of ​​the liquid guiding chamber 15 along its cross-section perpendicular to the axial direction. With this structure, since the cross-section of the liquid storage chamber 14 is larger than that of the liquid guiding chamber 15, the amount of aerosol matrix entering the liquid guiding chamber 15 from the liquid storage chamber 14 is limited by the reduced cross-section, thereby reducing the amount of aerosol matrix that can flow from the liquid storage chamber 14 into the liquid guiding chamber 15 per unit time, further slowing the entry of the aerosol matrix into the atomization channel 13.

[0048] In some alternative embodiments, please refer to Figures 3 to 5 To form two different but interconnected chambers, a liquid storage chamber 14 and a liquid guiding chamber 15, a recessed groove 52 is formed on the end face 51, into which the air guiding pipe 4 is inserted. The end face 51, the inner wall of the shell body 3, and the outer wall of the air guiding pipe 4 enclose the liquid storage chamber 14, while the groove wall of the groove 52 and the outer wall of the air guiding pipe 4 enclose the liquid guiding chamber 15. In other words, a step is formed on the surface of the end cap 5 facing the shell body 3. The higher part—that is, the end face 51, the shell body 3, and the air guiding pipe 4—encloses the liquid storage chamber 14, while the lower part—that is, the groove 52 and the air guiding pipe 4—encloses the liquid guiding chamber 15, forming a stepped transition between the chambers at the end cap 5.

[0049] In some alternative embodiments, please continue to refer to Figures 3 to 5To further slow the entry of the aerosol matrix from the storage chamber 14 into the guiding chamber 15, the end cap 5 can also be provided with multiple flanges 53 at the opening of the settling tank 52. These flanges 53 are spaced apart, and adjacent flanges 53 form guiding holes 54 connecting the storage chamber 14 and the guiding chamber 15. Because multiple flanges 53 are provided at the opening of the settling tank 52, the opening of the settling tank 52 is effectively reduced. The gaps between the flanges 53 form guiding holes 54, allowing the aerosol matrix to enter the guiding chamber 15 from the storage chamber 14 only through these holes. Due to the reduced area of ​​the guiding holes 54, the amount of aerosol matrix entering the guiding chamber 15 per unit time is further reduced, further slowing the entry of the aerosol matrix into the atomization channel 13, and thus further reducing the possibility of aerosol matrix leakage. The specific value of the cross-sectional area of ​​the guiding holes 54 can be within the range of 2 mm². 2 ~5mm 2 Within this range, the flow rate of the aerosol matrix will not be too fast due to the liquid guiding hole 54 being too large, nor will the aerosol matrix be unable to pass through due to the liquid guiding hole 54 being too small.

[0050] In some alternative embodiments, please refer to Figure 4 To facilitate the replenishment of aerosol matrix in the storage chamber 14, the end cap 5 may have an injection channel 55 and a corresponding on / off valve 56. The injection channel 55 communicates with the storage chamber 14 to allow the aerosol matrix to be injected into the storage chamber 14 from the outside. The on / off valve 56 controls the opening or closing of the injection channel 55. One or more injection channels 55 can be provided. When multiple injection channels 55 are provided, each injection channel 55 can be symmetrically arranged about the axial direction of the end cap 5. Because of the injection channel 55, the aerosol matrix can be replenished without replacing or disassembling the housing assembly 1. The on / off valve 56 switches the state of the injection channel 55, allowing it to switch between open and closed states, permitting the injection of the aerosol matrix only when it is open.

[0051] In some optional embodiments, to facilitate the control of the opening and closing of the injection channel 55 by the on / off valve 56, the on / off valve 56 may specifically include multiple elastic valves integrally formed on the end cap 5. These elastic valves elastically abut against each other in their natural state to close the injection channel 55. The purpose of providing elastic valves is that, in their natural state, the elastic valves maintain elastic abutment against each other, thereby closing the injection channel 55; then, when subjected to pressure from other components, the elastic valves separate, thereby opening the injection channel 55 and allowing injection. Therefore, an injection tube can be inserted into the injection channel 55 to press against and disrupt the connection between the elastic valves, thereby enabling the injection operation. After the injection tube is removed, the elastic valves automatically return to their elastic abutment state to close the injection channel 55.

[0052] In some alternative embodiments, please refer to Figure 6 To facilitate an electrical connection between the atomizing device and the power supply device, the atomizing device may further include an electrode holder 6. The electrode holder 6 has a positioning post 61 for insertion into the liquid injection channel 55, thereby fixing the electrode holder 6 to the end cap 5. The electrode holder 6 is used to fix the power supply electrode 62. To facilitate connection, the positioning post 61 can be inserted into the liquid injection channel 55 using the space formed by the electrode holder 6, thus fixing the electrode holder 6 to the end cap 5.

[0053] In some alternative embodiments, please refer to Figure 6 and Figure 7 The atomizing component 2 includes a heating element 21 and a conductive pin 22 electrically connected to the heating element 21. In order to facilitate the electrical connection between the conductive pin 22 and the power supply electrode 62, the power supply electrode 62 is fixedly provided on the electrode base 6. A circuit channel is provided between the electrode base 6 and the end cover 5 for the conductive pin 22 to pass through, so that the conductive pin 22 is electrically connected to the power supply electrode 62.

[0054] According to the atomizing device provided in the embodiments of this application, since the atomizing component 2 is connected to the liquid storage chamber 14 through the liquid guiding chamber 15, the atomizing component 2 is not directly immersed in the liquid storage chamber 14. The aerosol matrix in the liquid storage chamber 14 will slow down the flow into the atomizing component 2 through the transition of the liquid guiding chamber 15, thereby reducing the possibility of aerosol matrix leakage and improving the user experience.

[0055] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
