Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomizer and atomization device. Background Technology

[0002] A nebulizer is a structure that heats and atomizes a liquid. To ensure its long-term use, it contains a refill bottle with a switch at the opening. This switch allows for the refilling of the bottle with liquid into the atomizing chamber. Because the atomizing chamber is relatively large and relatively sealed, the liquid flows slowly from the refill bottle to the atomizer core. During refilling, the liquid first flows slowly from the refill bottle to the corresponding atomizing chamber on one side of the bottle. Only when the chamber on that side is nearly full does the liquid slowly flow towards the atomizer core. Utility Model Content

[0037] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0038] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0039] Please see Figures 1-7 One embodiment of this application provides an atomizer, including: an atomizing chamber 10, a sealing cap 20, an atomizing core 30, a replenishment bottle 40, and a replenishment switching switch 50.

[0040] A liquid replenishment port 21 is provided on the sealing cap 20. The sealing cap 20 and the opening of the atomizing chamber 10 are sealed together, forming an atomizing cavity. The atomizing core 30 is fixed between the atomizing chamber 10 and the sealing cap 20, and the atomizing core 30 and the liquid replenishment port 21 are radially spaced. The liquid replenishment bottle 40 is located at the end of the sealing cap 20 away from the atomizing chamber 10, and the bottle opening of the liquid replenishment bottle 40 is connected to the liquid replenishment port 21.

[0041] A liquid replenishment switch 50 is located at the liquid replenishment port 21. The liquid replenishment switch 50 is used to open or close the liquid replenishment port 21. The liquid replenishment bottle 40 stores atomizing liquid. When it is necessary to replenish the atomizing chamber with atomizing liquid, the atomizer is inverted to open the liquid replenishment port 21 and replenish or inject the atomizing liquid into the atomizing chamber. The atomizing core 30 is used to heat the atomizing liquid and transform it into a form that can be inhaled by the user. For example, the heated atomizing liquid becomes a mist or aerosol that can be inhaled by the user.

[0042] At least one exhaust groove 22 is provided on the inner wall of the atomizing chamber 10 near the sealing cap 20 and / or on the end face of the sealing cap 20 facing the atomizing chamber 10. The exhaust groove 22 extends from the liquid inlet 21 side toward the atomizing core 30 side. In order to make full use of the space in the atomizing chamber, the exhaust groove 22 can also extend past the atomizing core 30 toward the inner wall of the atomizing chamber 10.

[0043] Using the atomizer in the above embodiment, at least one exhaust groove 22 is provided on the inner wall of the atomizing chamber 10 near the sealing cover 20 and / or on the end face of the sealing cover 20 facing the atomizing chamber 10. The exhaust groove 22 extends from the liquid inlet 21 side to the atomizing core 30 side. When the inverted atomizer replenishes liquid into the atomizing chamber, the gas in the atomizing chamber first flows from the atomizing chamber around the liquid inlet 21 to the atomizing chamber around the atomizing core 30, and then flows from the atomizing chamber around the atomizing core 30 to the atomizing chamber around the liquid inlet 21 through the exhaust groove 22 near the opening of the atomizing chamber 10, forming an airflow circuit, thereby increasing the flow speed of the atomized liquid in the atomizing chamber and improving the liquid replenishment efficiency.

[0044] Please see Figures 1-2 as well as Figure 5An exhaust groove 22 is provided on one end face of the sealing cap 20 facing the atomizing chamber 10. When the inverted atomizer is replenished with liquid, the exhaust groove 22 is located at the top of the atomizing chamber. When the atomized liquid in the replenishment bottle 40 flows to the bottom of the atomizing chamber 10, the airflow flows towards the sealing cap 20. There is sufficient contact area between the sealing cap 20 and the airflow. The exhaust groove 22 on the sealing cap 20 facilitates a sufficient exhaust effect, thereby ensuring the replenishment efficiency.

[0045] The number, depth, and width of the exhaust grooves 22 can be specifically designed according to the actual space within the atomizing chamber and the liquid replenishment rate. For example, given the structure within the atomizing chamber 10, where the liquid replenishment rate is relatively slow and there is a greater need to increase the replenishment rate, more exhaust grooves 22 can be provided, and / or the depth of the exhaust grooves 22 can be increased to fully ensure the exhaust effect. Alternatively, exhaust grooves 22 can be simultaneously provided on the inner wall of the atomizing chamber 10 and the end face of the sealing cap 20 to provide sufficient flow channels for the airflow and improve the liquid replenishment rate.

[0046] Please see Figure 5 A mounting groove 23 is formed at the end of the sealing cap 20 facing the atomizing chamber 10, and a liquid replenishment port 21 is formed at the bottom of the mounting groove 23. The mounting groove 23 provides sufficient operating space for the liquid replenishment switch 50, thereby enabling the liquid replenishment port 21 to be blocked or opened. At the same time, the groove structure design, compared with the convex ring structure design, does not obstruct the flow of atomized liquid at the liquid replenishment port 21. One end of the exhaust groove 22 extends to the mounting groove 23, and the exhaust groove 22 and the mounting groove 23 are connected. In this way, the airflow in the atomizing chamber can flow back into the mounting groove 23, which can more fully return the airflow around the atomizing core 30 to the liquid replenishment port 21, which helps to improve the liquid replenishment efficiency.

[0047] Please see Figure 5 A transfer groove 24 is formed at the end of the sealing cap 20 facing the atomizing chamber 10. The two ends of the transfer groove 24 are connected to the exhaust groove 22 and the assembly groove 23, respectively. That is, the exhaust groove 22 is connected to the assembly groove 23 through the transfer groove 24. The bottom of the transfer groove 24 is inclined relative to the axis of the liquid replenishment port 21, meaning the surface of the transfer groove 24 is inclined relative to the bottom of the assembly groove 23 or the bottom of the exhaust groove 22. The inclined bottom of the transfer groove 24 serves two purposes: firstly, it guides the airflow into the assembly groove 23; secondly, it provides more space for the flowing air, allowing more airflow to pass through, increasing the airflow velocity, and ensuring liquid replenishment efficiency.

[0048] Please see Figure 5More preferably, the exhaust grooves 22 on the sealing cover 20 are configured as multiple exhaust grooves 22, all of which are connected to the mounting groove 23 through the same transfer groove 24. For example, two exhaust grooves 22 are configured, and the two exhaust grooves 22 are connected to the mounting groove 23 through a transfer groove 24. Configuring multiple exhaust grooves 22 facilitates ensuring or improving the airflow velocity within the atomizing chamber. The fact that multiple exhaust grooves 22 are connected to the same transfer groove 24, which has a relatively greater depth, provides sufficient flow space for the airflow while avoiding an excessive number of transfer grooves 24, which could reduce the wall strength of the mounting groove 23.

[0049] In other embodiments, the number of exhaust grooves 22 and the number of transfer grooves 24 can be flexibly set according to the space in the atomizing chamber or the liquid injection speed requirements. For example, four exhaust grooves 22 and two transfer grooves 24 can be configured, with one transfer groove 24 corresponding to two exhaust grooves 22. Alternatively, for another example, one exhaust groove 22 and one transfer groove 24 can be configured. In this case, to ensure the exhaust effect, the exhaust groove 22 can form a multi-segment curve with bends on the end face of the sealing cover 20. That is, by extending the length of the exhaust groove 22, sufficient flow space is provided for the gas in the atomizing chamber, thereby ensuring the flow speed of the gas in the atomizing chamber and improving the liquid replenishment speed.

[0050] Please see Figure 1 as well as Figures 8-9 Specifically, in this embodiment, the liquid replenishment switch 50 is a gravity ball disposed within the atomization chamber, and the gravity ball can move axially along the liquid replenishment port 21 (e.g., Figure 8 (Vertical direction) Approaching or moving away from the liquid inlet 21. The shape of the liquid inlet 21 is adapted to the shape of the gravity ball so that the gravity ball can block the liquid inlet 21. When the liquid inlet switch 50 is in gravity ball mode, the atomizer or atomizing device containing an atomizer is placed upright, such as... Figure 8 As shown, due to gravity, the gravity ball presses down on the replenishment port 21, effectively sealing it. At this time, the spaces within the atomizing chamber and the replenishment bottle 40 are isolated, preventing the atomized liquid in the atomizing chamber from flowing into the replenishment bottle 40. When it is necessary to replenish the atomizing liquid into the atomizing chamber, the atomizer or atomizing device containing an atomizer is inverted, for example... Figure 9 As shown, due to gravity, the gravity ball moves away from the liquid inlet 21 to the bottom side of the atomizing chamber 10. At this time, the liquid inlet 21 is opened, and the atomizing liquid in the liquid bottle 40 flows into the atomizing chamber.

[0051] Even better, to ensure the effectiveness of the gravity ball, it is made of a high-density material, such as stainless steel. To ensure the seal when the gravity ball blocks the fluid inlet 21, the opening of the fluid inlet 21 is an annular arc surface, and the annular arc surface and the gravity ball are in surface-to-surface contact.

[0052] The liquid replenishment switch 50, employing a gravity ball design, is simple in structure and easy to operate. The liquid replenishment port 21 can be opened or closed simply by adjusting the placement or orientation of the atomizer. In other embodiments, the liquid replenishment switch 50 can also be a top-press switch. In this case, part of the liquid replenishment switch 50 is located inside the atomization chamber, and part is located on the outside of the atomization chamber 10, facilitating user operation by pressing. When liquid replenishment is needed, the atomizer is inverted, and the user presses the top-press switch to open the liquid replenishment port 21, thus enabling liquid replenishment.

[0053] Please see Figures 1-2 In this embodiment of the application, the atomizer also includes a bracket 60, which is fixedly connected to the end of the sealing cap 20 away from the atomizing chamber 10. The bracket 60 has an avoidance opening 61 corresponding to the liquid replenishment port 21. The end of the bracket 60 away from the sealing cap 20 is provided with an installation tube 62, and the avoidance opening 61 is located inside the installation tube 62. The liquid replenishment bottle 40 and the installation tube 62 are detachably connected.

[0054] The sealing cap 20, such as a silicone sealing cap, has its outer wall tightly fitted to the inner wall of the atomizing chamber 10, ensuring a tight seal between the sealing cap 20 and the atomizing chamber 10. The frame shape of the bracket 60 matches the frame shape of the sealing cap 20, allowing the bracket 60 to not only be fixedly connected to the sealing cap 20 but also to be fitted and fixed inside the opening of the atomizing chamber 10, thus ensuring the connection strength of the sealing cap 20 on the atomizing chamber 10. The radial dimension of the clearance port 61 is not less than the radial dimension of the replenishment port 21, so that the atomizing liquid in the replenishment bottle 40 can pass through the replenishment port 21. For example, the clearance port 61 and the replenishment port 21 have the same shape and size.

[0055] To facilitate processing and fixation of the replenishment bottle 40, an assembly tube 70 is sleeved inside the mounting tube 62. The bottle mouth of the replenishment bottle 40 is indirectly fixed to the clearance opening 61 of the bracket 60 through a detachable connection with the assembly tube 70. For example, the bottle mouth of the replenishment bottle 40 and the inner wall of the assembly tube 70 are tightly fitted, snapped together, or threaded together. Specifically, in this embodiment, the inner wall of the assembly tube 70 is provided with internal threads, the bottle mouth of the replenishment bottle 40 is provided with external threads, and the replenishment bottle 40 and the assembly tube 70 are threaded together.

[0056] Preferably, the atomizer also includes a reset structure 80, located at the end of the gravity ball near the atomization chamber 10. When the replenishment bottle 40 is connected to the mounting tube 62, the reset structure 80 ensures the movement space of the gravity ball. When the replenishment bottle 40 is removed from the mounting tube 62, the reset structure 80 abuts against the gravity ball to seal the replenishment port 21. By setting the reset structure 80, when replacing the replenishment bottle 40, after the replenishment bottle 40 is removed from the bracket 60, the gravity ball can be firmly restricted at the replenishment port 21, preventing the atomized liquid in the atomization chamber from flowing out. At this time, due to the abutment action of the reset structure 80 against the gravity ball, there are no restrictions on the placement position and method of the atomizer, that is, the atomizer can be placed at any angle without the atomized liquid flowing out from the replenishment port 21. This simplifies the replacement steps or methods of the replenishment bottle 40, improves the replacement efficiency of the replenishment bottle 40, and provides users with a better user experience.

[0057] Please see Figure 1 Specifically, the reset structure 80 includes an elastic reset member 81 and a limiting member 82. The elastic reset member 81 is located inside the atomizing chamber, and one end of the elastic reset member 81 abuts against the atomizing chamber 10. A first clearance hole 25 is provided on the sealing cap 20 around the liquid filling port 21, and a second clearance hole 63 is provided on the bracket 60 around the clearance port 61. One end of the limiting member 82 passes through the second clearance hole 63 and the first clearance hole 25 and abuts against the elastic reset member 81, while the other end of the limiting member 82 abuts against the mouth of the liquid filling bottle 40. When the limiting member 82 abuts against the liquid filling bottle 40, the elastic reset member 81 is in a compressed state. The shapes of the first clearance hole 25 and the second clearance hole 63 can be consistent, and both are consistent with the structural shape of the limiting member 82 as it passes through the atomizing chamber, thereby facilitating the sealing of the atomizing chamber.

[0058] Please see Figure 2 More specifically, the elastic reset member 81 includes a sleeve 811 and a spring 812. A partition 813 is provided inside the sleeve 811, dividing the space within the sleeve 811 axially into a first space 811a and a second space 811b. The first space 811a is located on the side away from the sealing cover 20, and the second space 811b is located on the side closer to the sealing cover 20. The partition 813 can be plate-shaped, block-shaped, etc. For example, the partition 813 is plate-shaped, and the plate-shaped partition 813 has a curved surface 8131 on the side facing the second space 811b, which is used to contact the gravitational spherical surface.

[0059] Spring 812 is disposed in the first space 811a. A docking post 11 is provided in the bottom of the atomizing chamber 10, and spring 812 is sleeved on the outside of the docking post 11. When the limiting member 82 and the replenishment bottle 40 abut, spring 812 is in a compressed state. Thus, after the replenishment bottle 40 is subsequently disassembled, the compressed spring 812 will abut against the gravity ball by restoring its deformation.

[0060] To ensure the installation strength of the elastic reset component 81 within the atomization chamber, a guide and limiting structure is also provided around the outer circumference of the docking post 11, for example... Figure 3 As shown, multiple guide members 12 arranged in a ring array are arranged around the outer circumference of the docking post 11. The guide members 12 have a plate-like structure. The sleeve 811 on one side of the first space 811a is sleeved between the docking post 11 and the guide members 12. Through the multiple guide members 12, the installation of the sleeve 811 in the atomization chamber can be assisted, and the radial position of the sleeve 811 relative to the docking post 11 in the atomization chamber can be restricted.

[0061] The limiting member 82 includes a limiting plate 821 and a limiting ring 822 connected to each other. Multiple limiting plates 821 are configured and spaced circumferentially along the limiting ring 822. The multiple limiting plates 821 are snap-fitted to the sleeve 811 on the second space 811b. The limiting ring 822 abuts against the replenishment bottle 40. For example... Figure 2 As shown, two limiting plates 821 are configured. The number of first clearance holes 25 and second clearance holes 63 is the same as the number of limiting plates 821. The two limiting plates 821 are arc-shaped plates symmetrically distributed relative to the axis of the limiting ring 822. Correspondingly, the first clearance holes 25 and the second clearance holes 63 are both arc-shaped holes. The limiting member 82 includes multiple circumferentially spaced limiting plates 821, which can reduce the weight of the limiting member 82 and reduce the size of the corresponding first clearance holes 25 and second clearance holes 63, thereby ensuring the sealing of the atomizing chamber at the first clearance holes 25 and the second clearance holes 63.

[0062] Correspondingly, the sleeve 811 at the second space 811b may include multiple circumferentially spaced baffles 8111, with each baffle 8111 corresponding to a limiting plate 821. A hook 8112 is provided on the inner wall of the baffle 8111, and a locking hole is provided on the limiting plate 821, with the locking hole and hook 8112 engaging. More preferably, anti-rotation portions 8113 are also provided at both ends of the baffle 8111 circumferentially. The anti-rotation portions 8113 may be plate-shaped, block-shaped, etc., as long as they can restrict the circumferential rotation of the limiting plate 821 within the baffle 8111.

[0063] Please see Figure 3 The limiting component 82 also includes a sealing ring 823. The outer circumference of the limiting ring 822 has multiple first teeth 8221, and the inner circumference of the sealing ring 823 has multiple corresponding second teeth 8231. The first teeth 8221 and second teeth 8231 mesh with each other. The two ends of the sealing ring 823 abut against the openings of the bracket 60 and the replenishment bottle 40, respectively. The sealing ring 823 ensures both the sealing within the atomization chamber and the sealing at the opening of the replenishment bottle 40.

[0064] To ensure the connection strength between the sealing ring 823 and the limiting ring 822, a groove can be provided inside the end of the sealing ring 823 facing the limiting ring 822, and a convex ring is provided inside the end of the limiting ring 822 facing the sealing ring 823. Multiple first teeth 8221 are provided on the outer periphery of the convex ring. Thus, the sealing ring 823 and the limiting ring 822 can be fitted together through the groove and the convex ring. Combined with the meshing of the first teeth 8221 and the second teeth 8231, the connection strength between the sealing ring 823 and the limiting ring 822 can be guaranteed. For ease of processing, the limiting plate 821 and the limiting ring 822 in the limiting member 82 are made of hard plastic (e.g., PEEK), while the sealing ring 823 is made of soft plastic (e.g., silicone).

[0065] The nebulizer in the above embodiments of this application, when replenishing liquid, such as Figure 9 As shown, when the atomizer is inverted, the gravity ball inside the atomization chamber moves downwards due to gravity, opening or exposing the liquid inlet 21. The atomizing liquid in the liquid bottle 40 flows through the liquid inlet 21 into the atomization chamber on one side of the atomizing core 30 (e.g., Figure 9 (As shown by the black arrow pointing to the right). Because the atomizing liquid is positioned relatively lower during replenishment, the top of the atomizing chamber (i.e., the side near the sealing cap 20) is empty. Therefore, while replenishing the atomizing chamber, the air inside the atomizing chamber also flows upward and moves towards the assembly groove 23 through the exhaust groove 22 on the sealing cap 20 (e.g., ...). Figure 9 (As shown by the black arrow pointing to the left). The airflow within the atomization chamber forms a relatively complete airflow loop, improving the efficiency of liquid replenishment. Using the atomizer designed in this application, the liquid replenishment operation can be completed in approximately ten seconds. After the replenishment operation is complete, the atomizer is then placed upright, for example, as shown... Figure 8 As shown. If an existing atomizer is used for replenishment, the atomization chamber is a relatively closed cavity, and the flow rate of the atomized liquid inside the atomization chamber is slow. It may take one or two minutes to complete the replenishment. In addition, the atomizer needs to be tilted during replenishment to help the atomized liquid flow to the atomization chamber on the side of the atomizing core 30.

[0066] Please see Figures 1-9 In another embodiment of this application, an atomizing device is provided, including an atomizer and an airflow switch 130, wherein the atomizer is the atomizer in the above embodiment.

[0067] The atomizer includes a mouthpiece 100, which is fixed to the bottom of the atomizing chamber 10. The mouthpiece 100 has a suction tube 101 and an air vent tube 102 inside, and the suction tube 101 is connected to the atomizing core 30. The atomizing chamber 10 has a first air vent 13, and the sealing cap 20 has an air vent 26. The two ends of the first air vent 13 are respectively connected to the air vent tube 102 and the air vent 26.

[0068] The airflow switch 130 is located at the end of the vent 26 away from the atomizing chamber 10. The airflow switch 130 is connected to the outside through the vent 26, the first vent column 13 and the vent pipe 102. The airflow switch 130 is used to control the working state of the atomizing core 30.

[0069] The airflow switch 130, for example, is a microphone. The airflow switch 130 and the external airflow channel are independent of the atomizing airflow channel within the atomizing core 30. This effectively prevents the aerosol formed after the atomized liquid in the atomizing core 30 is heated and atomized from flowing to the airflow switch 130, thus preventing the condensed aerosol from corroding the airflow switch 130. Furthermore, the airflow switch 130 is located relatively close to the mouthpiece 100. When the user inhales through the mouthpiece 100, the airflow switch 130 can simultaneously sense the airflow, facilitating timely control of the atomizing core 30's operating status.

[0070] Specifically, the atomizing device also includes a mounting sleeve 140, an electrode post 150, a housing 160, a circuit board 170, and a battery cell 180.

[0071] The bracket 60 is provided with a second ventilation column 64 that is sleeved with the ventilation hole 26. The mounting sleeve 140 is fixed on the bracket 60 corresponding to the position of the atomizing core 30. The mounting sleeve 140 is provided with an assembly cavity. The airflow switch 130 is sleeved in the assembly cavity. The mounting sleeve 140 is provided with a third ventilation column that communicates with the assembly cavity. The third ventilation column and the second ventilation column 64 are sleeved together.

[0072] The atomizing core 30 includes an atomizing tube, a liquid-guiding cotton, and a heating element. The atomizing core 30 is used to heat and atomize the liquid within the atomizing chamber. The circuit board 170 and the battery cell 180 are both fixed inside the outer casing 160, and the electrode post 150 is fixed to the mounting sleeve 140. The heating element in the atomizing core 30 is electrically connected to the circuit board 170 via the electrode post 150. When the atomizer is inhaled, a flow path corresponding to the airflow switch 130 generates a flow path... Figure 8 The airflow is indicated by the black arrow. After the airflow switch 130 detects the airflow signal, it feeds the airflow signal back to the circuit board 170. The circuit board 170 controls the battery cell 180 to provide power to the heating element in the atomizing core 30. Otherwise, the circuit board 170 will disconnect the power supplied by the battery cell 180 to the heating element.

[0073] Please see Figures 1-5 as well as Figure 8 The atomizer also includes an atomizing base 90, an atomizing shell 110, and an air intake adjustment assembly 120.

[0074] The atomizing shell 110 is sleeved on the outside of the atomizing chamber 10. The atomizing chamber 10 has a first mounting port 14, the sealing cap 20 has a second mounting port 27, and the bracket 60 has a third mounting port 67. The first mounting port 14, the second mounting port 27, and the third mounting port 67 are coaxially arranged. One end of the atomizing tube in the atomizing core 30 is sleeved with the first mounting port 14, and the other end of the atomizing tube extends to the second mounting port 27. The atomizing base 90 is sleeved and fixed to the third mounting port 67, and the atomizing base 90 and the atomizing tube at the second mounting port 27 are sleeved together.

[0075] The air intake adjustment assembly 120 includes an air intake plate 121 and an adjustment column 122. The air intake plate 121 has multiple spaced-apart air intake holes 123. An adjustment hole 111 is provided on the atomizing shell 110, and a corresponding adjustment hole is also provided on the atomizing chamber 10. The air intake plate 121 is movably disposed within the atomizing chamber. One end of the adjustment column 122 is fixed to the air intake plate 121, and the other end of the adjustment column 122 passes through the adjustment hole 111 on the atomizing chamber 10 and the atomizing shell 110, extending to the outside. By adjusting the adjustment column 122, the number of exposed air intake holes 123 can be adjusted, thereby adjusting the air intake volume, allowing the airflow to enter the atomizing air passage formed within the atomizing tube through the side wall of the atomizing shell 110. In other embodiments, a bottom air intake method can also be used, for example, by providing an air intake port at the end of the outer shell 160 away from the mouthpiece 100.

[0076] Please see Figures 2-3 Specifically, in this embodiment, to facilitate the assembly of the atomizer, the sealing cap 20 and the bracket 60 are fitted together and fixed. For example, the sealing cap 20 has a first mating groove 28 and a second mating groove 29 on the side facing the bracket 60, and the bracket 60 has a first mating plate 65 and a second mating plate 66 on the side facing the sealing cap 20. The first mating plate 65 is tightly fitted into the first mating groove 28, and the second mating plate 66 is tightly fitted into the second mating groove 29.

[0077] For a better option, please refer to Figures 1-2 The number of exhaust channels 22 is even, and these even-numbered exhaust channels 22 are symmetrically distributed along the length direction of the atomizing chamber, which is perpendicular to both the axis of the liquid replenishment port 21 and the axis of the atomizing core 30. For example, the number of exhaust channels 22 may be two, four, or similar. Specifically, for example, one exhaust channel 22 may be provided on each side of the first ventilation column 13 within the atomizing chamber. The even-numbered symmetrically distributed exhaust channels 22 facilitate the exhaust operation of air at various locations within the atomizing chamber.

[0078] The atomizing device provided in this application embodiment contains the atomizer in the above embodiment, and therefore also has the advantages of the atomizer in the above embodiment, so it will not be described again here.

[0079] 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.
