Description

Atomizer and electronic atomization device

This application claims priority to Chinese patent application No. 202310657857X filed on June 5, 2023, with invention name “Atomizer and Electronic Atomization Device”, and incorporates it into this application by reference.

[Technical field]

The present application relates to the technical field of electronic atomization, and in particular to an atomizer and an electronic atomization device.

[Background technology]

The method of generating aerosol by a related atomizer is to use a heating element to heat a liquid atomization matrix to convert the atomization matrix into an aerosol, and then use airflow to transport the aerosol to the outside of the atomizer. It can be seen that the quality of the aerosol output by the atomizer is closely related to the atomization structure and airflow transport structure of the atomizer.

Traditional atomizers usually design the storage structure of the atomization matrix above the heating element, and use methods such as opening holes and setting guide pieces to allow the atomization matrix to flow to the heating element under the action of gravity and be atomized into an aerosol when heated; or, the storage structure of the atomization matrix is designed below the heating element, and pump pressure is used to allow the atomization matrix to be transported to the heating element against gravity and be atomized into an aerosol when heated. Among them, the former is limited by the design of the storage and transmission structure of the atomization matrix. After the aerosol is generated, it needs to pass through a long airway before it can be output, which inevitably leads to a certain quality loss of the aerosol during the transmission process; the latter is limited by the design of the pump pressure structure, and the storage capacity of the atomization matrix and the airflow transmission efficiency of the atomizer are relatively low, which makes it difficult for the atomizer to output high-quality aerosols and has a short service life.

It is understood that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

The present application provides an atomizer and an electronic atomization device.

Please refer to FIG. 1 , which is a schematic diagram of the exploded structure of an electronic atomization device provided in some embodiments of the present application.

In some embodiments, the electronic atomization device 1 includes an atomizer 10 and a controller 20. The controller 20 can be docked with the atomizer 10 and control the atomization of the atomizer 10. The atomizer 10 and the controller 20 can be designed as a detachable structure. An electrode 110 may be provided at the bottom of the atomizer 10. When the atomizer 10 is docked with the controller 20, the electrode 110 may be electrically connected to the power supply or circuit board of the controller 20 to establish a control relationship between the controller 20 and the atomizer 10. Among them, the electrode 110 may include a magnetic part for cooperating with the magnetic part in the controller 20 that is docked therewith to achieve magnetic fixation.

In other embodiments, the atomizer 10 and the controller 20 may also be designed as a non-detachable structure (in general use scenarios). The electrode 110 may be fixedly connected to the electronic device of the controller 20 as a part of the atomizer 10, or may be fixedly connected to the electronic device of the atomizer 10 as a part of the controller 20. The shape of the electrode 110 is not limited.

Optionally, the bottom surface of the atomizer 10 is further provided with a receiving groove 101, and the shape of the receiving groove 101 is adapted to the airflow sensor of the controller 20. When the atomizer 10 is docked with the controller 20, the airflow sensor can be accommodated in the receiving groove 101. In some embodiments, a plurality of receiving grooves 101 spaced apart from each other are provided on the bottom surface of the atomizer 10, and any of the receiving grooves 101 can be used to accommodate the airflow sensor to expand the atomizer. The angle range when the atomizer 10 and the controller 20 are connected is optional. For example, the airflow sensor of the controller 20 is located on the left side, and the atomizer 10 has two receiving grooves 101 located on the left and right sides respectively, so that the atomizer 10 has two optional connection angles, so that the front and back directions of the atomizer 10 do not need to be considered during connection.

When the airflow sensor senses the user's inhalation action, it can specifically sense the environmental negative pressure value, the gas flow rate value, the gas flow rate value, the acceleration value of the gas flow, etc. When the above-mentioned sensing values sensed by the airflow sensor exceed the internal threshold, the airflow sensor can send a trigger signal, and the circuit control element of the controller 20 controls the circuit connection between the power supply and the atomizer 10 based on the trigger signal.

In addition, the atomizer 10 also has an air inlet channel 102 connected to its bottom surface, and the controller 20 has an air inlet port 201. When the atomizer 10 and the controller 20 are connected, the air inlet channel 102 communicates with the air inlet port 201. The air inlet channel 102 can be located at the central axis of the atomizer 10, and the electrode 110 and the receiving groove 101 are both located at the periphery of the entrance of the air inlet channel 102.

Please refer to FIG. 2 , which is a schematic diagram of the exploded structure of an atomizer provided in some embodiments of the present application.

In some embodiments, the atomizer 10 includes a first shell 100 forming a bottom and a second shell 200 forming a top. Optionally, the first shell 100 and the second shell 200 both have an opening, and one end of the two shells provided with the opening can be butted together to form a housing of the atomizer 10. Other components of the atomizer 10 can be loaded into the first shell 100 and/or the second shell 200 through the openings thereof. Specifically, the atomizer 10 may include a liquid guide 300, a first sealing member (not shown), a second sealing member 500, a sealing ring 510, a third sealing member 600, a first liquid absorbing member (not shown), a second liquid absorbing member 720, a third liquid absorbing member 730, and the like.

Among them, the first shell 100 has an opening at one end and a circumferential edge thereof may be provided with a through hole or a groove as a mortise, and the second shell 200 has an opening at one end and a circumferential edge thereof may be provided with a protrusion as a matching tenon, so that the first shell 100 and the second shell 200 can be fixed by mortise and tenon joint when they are docked.

It can be understood that there are many optional docking structures between the first shell 100 and the second shell 200, and only one of them is shown above. Other docking structures include but are not limited to: the first shell 100 is provided with a tenon, and the second shell 200 is provided with a mortise, and the two are matched and snap-connected; the outer periphery of the first shell 100 and the inner periphery of the second shell 200 are provided with matching threads, and the two are screwed together with matching threads; and so on.

Please refer to FIG. 3 and FIG. 4 , FIG. 3 is a schematic diagram of the structure of a first shell provided in some embodiments of the present application, and FIG. 4 is a schematic diagram of the cross-sectional structure of the first shell in the embodiment of FIG. 3 .

In some embodiments, the first housing 100 has a bottom wall 120, and a first outer wall 130 and a first inner wall 140 extending from both ends of the bottom wall 120. The first inner wall 140 is arranged to form an air inlet channel 102, and the first outer wall 130 surrounds the first inner wall 140 and forms a liquid storage space 103 with the bottom wall 120 and the first inner wall 140.

The liquid storage space 103 can be used to store liquid atomized matrix. An opening is formed at one end of the first outer wall 130 away from the bottom wall 120, and the atomized matrix can be injected into the liquid storage space 103 through the opening. The conventional method of injecting the atomized matrix from the bottom does not require the first housing 100 of the present design to be inverted for oil injection, and then turned upright after assembly, which not only improves assembly efficiency but also prevents the atomized matrix from leaking from the bottom. The inner circumference of the first outer wall 130 may be provided with ribs 1301 extending in the axial direction, which may play a role in strengthening and draining.

Among them, the first outer wall 130 forms a partial shell of the atomizer 10, which can be used to dock with the second shell 200. The height of the first inner wall 140 in the axial direction can be less than the first outer wall 130, so as to facilitate the installation of other components of the atomizer 10 within the first outer wall 130. The bottom wall 120 forms the bottom of the atomizer 10, and its bottom surface can be used to set the above-mentioned accommodating groove 101. Among them, the cross-section of the first outer wall 130 and the first inner wall 140 along the axial direction is circular to form a cylindrical shell structure. It can be understood that the first shell 100 can also be designed as a cylindrical structure or a non-columnar structure with an elliptical cross-section, a square cross-section or a cross-section of other shapes as needed.

Optionally, the first inner wall 140 is located at a middle position of the bottom wall 120 , so that the air intake passage 102 is located on the central axis of the first shell 100 .

Please refer to FIG. 5 , which is a cross-sectional schematic diagram of a partial structure of an atomizer provided in some embodiments of the present application.

In some embodiments, the liquid guide 300 of the atomizer 10 is a porous medium of an integral structure, such as ceramic, organic cotton, porous fiber material, etc. The liquid guide 300 can use its own capillary force to absorb and transport the atomized matrix. The atomizer 10 also includes a heating element 330 at least partially in contact with the liquid guide 300, and the heating element 330 is used to heat the atomized matrix on the liquid guide 300 to atomize it into an aerosol.

Specifically, the liquid guide 300 has a liquid guide portion 310 and a liquid storage portion 320 of an integrated structure. At least part of the structure of the heating element 330 is in contact with the liquid storage portion 320, and the specific installation method is not limited. For example, the heating element 330 can be arranged on the liquid storage portion 320 by attachment, embedding, etc. The atomizer 10 also includes a pin 340 connected to the heating element 330, and the pin 340 is used to form a circuit between the heating element 330 and the power supply. Specifically, it can be welded or pressed on the electrode 110 and electrically connected to the electrode 110.

The liquid storage part 320 may be arranged to form an atomization space 301, and the heating element 330 may be at least partially exposed in the atomization space 301. For example, the heating element 330 may be arranged on the inner peripheral wall of the liquid storage part 320 exposed to the atomization space 301, so that after the atomization matrix on the liquid storage part 320 is heated and atomized, an aerosol may be generated in the atomization space 301. The heating element 330 may be in an annular mesh shape to expand the contact area between the heating element 330 and the liquid storage part 320 and improve the atomization efficiency. The heating element 330 may be attached to the inner peripheral wall of the liquid storage part 320.

It should be noted that the heating element 330 may be a closed or non-closed annular structure, and its shape may be designed to be a mesh, sheet, belt, wire, etc. as needed, and is not specifically limited here.

The liquid guide 300 may be in the shape of a hollow cylinder, or other hollow shapes. The inner diameter of the portion 310 is greater than the inner diameter of the liquid storage portion 320. That is, the inner aperture of the liquid storage portion 320 is smaller than the inner aperture of the liquid guide portion 310. As a result, the atomization space 301 formed by the liquid storage portion 320 is small in volume, and when the heating element 330 is working, the temperature inside the atomization space rises quickly, which is conducive to improving the atomization efficiency of the atomized matrix. Optionally, the outer wall of the liquid guide portion 310 and the liquid storage portion 320 is smoothly transitioned, and the thickness of the liquid storage portion 320 is greater than the thickness of the liquid guide portion 310. The thickness of the liquid guide portion 310 is uniform, that is, the thickness of the liquid guide portion 310 from one end close to the liquid storage portion 320 to the other end away from the liquid storage portion 320 remains substantially unchanged to ensure that the atomized matrix transmission rate is stable. Similarly, the thickness of the liquid storage portion 320 is uniform.

Optionally, the liquid-conducting portion 310 and the liquid-storing portion 320 may be in the shape of a hollow cylinder. The liquid-conducting portion 310 and the liquid-storing portion 320 may be respectively surrounded by cylindrical channels, and the two channels may be coaxially arranged. Of course, the liquid-conducting portion 310 and the liquid-storing portion 320 are not limited to the above-mentioned cylindrical shape, and may also be designed in other shapes, including but not limited to prisms, elliptical cylinders, etc.

It should be understood that the liquid guide portion 310 may also be partially or completely designed as a non-hollow structure. For example, the liquid guide portion 310 extends from one end of the liquid storage portion 320 and is in a solid columnar, cone-shaped, etc. shape and extends into the liquid storage space 103.

Please refer to FIG. 6 , which is a schematic cross-sectional view of the atomizer provided in some embodiments of the present application.

In some embodiments, one end of the liquid guide portion 310 of the liquid guide member 300 away from the liquid storage portion 320 is located in the liquid storage space 103, and is used to transfer the atomized matrix in the liquid storage space 103 to the liquid storage portion 320. Among them, the liquid guide portion 310 can be sleeved on the first inner wall 140. One end of the liquid guide portion 310 away from the liquid storage portion 320 can be against the bottom wall 120, and is used to contact the atomized matrix in the liquid storage space 103 and transfer the atomized matrix to the liquid storage portion 320. The liquid storage portion 320 can be located on the upper side of the first inner wall 140, that is, the side of the first inner wall 140 away from the bottom wall 120. For example, the liquid storage portion 320 can protrude from the inner circumferential surface of the liquid guide portion 310, and the protruding portion is located on the upper side of the first inner wall 140.

With this design, the liquid guide portion 310 can absorb the liquid atomized matrix stored in the liquid storage space 103 through its own capillary force and transport it upward to the liquid storage portion 320. Thus, the atomized matrix can be transported from the liquid storage space 103 to the liquid storage portion 320 above the first inner wall 140, and then further heated and atomized into aerosol and input into the atomization space 301.

It should be noted that during the use of the atomizer 10, the internal pressure of the liquid storage space 103 is easily less than the external pressure due to factors such as shell vibration, temperature/humidity changes, and imbalance between the consumption and supply of the atomized matrix. The conventional atomized matrix liquid guide structure is very likely to cause leakage. The embodiment of the present application uses an integrated liquid guide part 300 to transfer the atomized matrix from bottom to top. Since the capillary force of the liquid guide part 300 tends to be fixed and has a saturated oil storage state, the liquid guide part 300 is not easy to change the transportation efficiency of the atomized matrix due to the negative pressure of the liquid storage space 103, which is beneficial to improve the stability of the atomized matrix transmission, thereby preventing the taste of the aerosol output by the atomizer 10 from deteriorating.

In addition, by designing the liquid guiding member 300 to have a structure with a liquid guiding portion 310 and a liquid storage portion 320, the problem of insufficient liquid supply caused by improper liquid conduction can be avoided. That is, a liquid storage area specially designed at the top of the liquid guiding member 300 can ensure the consistency of aerosol output.

By extending the liquid guide portion 310 to the bottom wall 120, the efficiency of the transport of the atomized matrix will not change due to the change of the liquid level in the liquid storage space 103, that is, the liquid guide portion 310 can always be in contact with the atomized matrix until the atomized matrix in the liquid storage space 103 is exhausted. It can be understood that in some embodiments, the end of the liquid guide portion 310 away from the liquid storage portion 320 can also be spaced from the bottom wall 120.

It should be noted that the storage of the atomized matrix in the atomization space 301 includes but is not limited to: the atomized matrix is directly stored in the atomization space 301 and contacts the bottom wall 120 , the liquid storage medium storing the atomized matrix is accommodated in the atomization space 301 , and the atomized matrix is stored in the liquid guide portion 310 in the atomization space 301 .

In the above embodiment, the atomized matrix is directly stored in the atomization space 301 and in contact with the bottom wall 120. In some embodiments, the atomized matrix can be stored in a liquid storage medium accommodated in the atomization space 301, and one end of the liquid guide portion 310 away from the liquid storage portion 320 is connected to the liquid storage medium for transporting the atomized matrix on the liquid storage medium to the liquid storage portion 320. In other embodiments, the atomized matrix can be stored in the liquid guide portion 310, and the thickness of the liquid guide portion 310 can be greater than that of the liquid storage portion 320, for example, the liquid guide portion 310 can fill the atomization space 301.

In some embodiments, the second housing 200 of the atomizer 10 is disposed at one end of the first outer wall 130 away from the bottom wall 120, and has an air outlet 2101 communicating with the air inlet channel 102. Optionally, the second housing 200 has a second inner wall 210, and a second outer wall 220 surrounding the second inner wall 210. The second inner wall 210 is arranged to form an air outlet channel 2102. The air outlet 2101 is disposed at one end of the second inner wall 210 away from the bottom wall 120, and communicates with one end of the air outlet channel 2102. The second outer wall 220 forms a partial outer shell of the atomizer 10. One end of the second outer wall 220 is butted against one end of the first outer wall 130 away from the bottom wall 120.

Optionally, the liquid storage part 320 may be located between the first inner wall 140 and the second inner wall 210. The air inlet channel 102 surrounded by the first inner wall 140, the atomization space 301 surrounded by the liquid storage part 320, and the other end of the air outlet channel 2102 surrounded by the second inner wall 210 may be connected in sequence, so that the airflow entering the atomizer 10 from the air inlet channel 102 may pass through the atomization space 301 and the air outlet channel 2102 in sequence, and then be output from the air outlet 2101, and the aerosol in the atomization space 301 may be output from the air outlet 2101 along with the airflow in this process. The air inlet channel 102, the atomization space 301, and the air outlet channel 2102 may be coaxially arranged.

This design reduces the length of the airway that the aerosol needs to pass through for output. Specifically, compared with conventional products, the length of the airway can be reduced from more than 40 mm to less than 20 mm, thereby reducing the amount of smoke, sweetness and flavor loss during the aerosol output process, which is beneficial to improving the quality of the aerosol output by the atomizer 10.

It should be noted that the second housing 200 of the atomizer 10 is not limited to the above structure. Please refer to Figure 7, which is a schematic cross-sectional view of the atomizer provided in some embodiments of the present application.

In some embodiments, the second housing 200 may be a plate disposed on one end of the first outer wall 130 away from the bottom wall 120 and having an air outlet 2101 communicating with the air inlet channel 102. The liquid storage portion 320 may be disposed between the second housing 200 and the first inner wall 140.

Optionally, the liquid storage part 320 is surrounded to form an atomization space 301 , the air inlet channel 102 , the atomization space 301 and the air outlet 2101 are connected in sequence, and the heating element 330 is at least partially in contact with the liquid storage part 320 and at least partially exposed to the atomization space 301 .

It is understandable that the second shell 200 can also be designed as other structures as needed, such as a nozzle-shaped structure, a cylindrical structure, etc., as long as it can be docked with the first outer wall 130 and has an air outlet 2101 connected to the air inlet channel 102, so that the airflow input from the air inlet channel 102 can entrain the aerosol and be output from the air outlet 2101.

Please refer to FIG. 8 , which is a schematic cross-sectional view of the atomizer provided in some embodiments of the present application.

In some embodiments, the first sealing member 400 of the atomizer 10 is sealingly disposed between the liquid storage portion 320 and the first inner wall 140. Specifically, one end of the first sealing member 400 abuts against the bottom surface of the liquid storage portion 320, and the other end abuts against the top surface of the first inner wall 140, so as to prevent the atomized matrix from leaking into the air inlet channel 102 through the gap between the liquid storage portion 320 and the first inner wall 140.

Optionally, the first sealing member 400 includes a barrier portion 410 located between the liquid storage portion 320 and the first inner wall 140, and an extension portion 420 extending from one end of the barrier portion 410 away from the liquid storage portion 320. The barrier portion 410 and the extension portion 420 are bent. The outer peripheral wall of the barrier portion 410 contacts the liquid guide portion 310 and can be interference fit with the liquid guide portion 310. The outer peripheral wall of the extension portion 420 contacts the inner peripheral surface of the first inner wall 140 and can be interference fit with the first inner wall 140.

Among them, the first seal 400 can be an annular sealing sleeve, which can be mounted on the top of the first inner wall 140 to improve the assembly stability and sealing of the first seal 400. It can be understood that the first seal 400 is not limited to this embodiment. For example, the first seal 400 can be a silicone ring.

It should be noted that the first sealing member 400 has a heat-insulating function in addition to a sealing function. Specifically, the first sealing member 400 may be made of silicone, which has good heat resistance, while the first housing 100 may be made of a material with poor heat resistance, such as plastic. By sealing the first sealing member 400 at the top of the first inner wall 140, the heat of the heating element 330 can be blocked from being transferred to the first inner wall 140, thereby preventing the first inner wall 140 from being heated and generating odor.

In addition, in some embodiments, the second sealing member 500 of the atomizer 10 is disposed between the first outer wall 130 and the liquid guide member 300 to seal the liquid storage space 103. The second sealing member 500 can be sleeved on the liquid guide member 300 and abut against the first outer wall 130 to prevent the atomized matrix in the liquid storage space 103 from splashing out.

In some embodiments, the second sealing member 500 may contact the convex portion on the inner circumferential surface of the first outer wall 130. The rib 1301 serves to limit the second sealing member 500. During assembly, the second sealing member 500 can be installed into the first housing 100 from the opening at the side of the first outer wall 130 away from the bottom wall 120 and move to abut against the rib 1301. The rib 1301 can support the second sealing member 500.

The third seal 600 of the atomizer 10 can be sealed at one end of the second seal 500 away from the bottom wall 120 and located on the upper side of the liquid storage portion 320 to prevent the atomized matrix on the liquid storage portion 320 from splashing out. The third seal 600 can have a through hole coaxially arranged with the gas outlet channel 2102.

Optionally, one end of the second sealing member 500 away from the bottom wall 120 protrudes from one end of the liquid storage portion 320 away from the bottom wall 120, that is, the top end of the second sealing member 500 protrudes from the top end of the liquid storage portion 320. The third sealing member 600 can contact the top of the second sealing member 500 and have an interference fit with the inner peripheral wall of the second sealing member 500 to achieve a good sealing effect. The bottom of the third sealing member 600 can also contact the liquid storage portion 320 to cooperate with the first sealing member 400 to achieve stable assembly of the liquid guide member 300.

Of course, the assembly design of the third seal 600 and the second seal 500 is not limited to this. For example, the third seal 600 can be sleeved on the second seal 500 and abut against the outer peripheral surface of the second seal 500. For another example, the bottom surface of the third seal 600 can be snap-connected with the top surface of the second seal 500; the relative height of the top end of the second seal 500 protruding from the top end of the liquid storage portion 320 can be designed as needed.

Please refer to FIG. 9 , which is a schematic diagram of the structure of a third sealing member provided in some embodiments of the present application.

In some embodiments, at least one annular protrusion 610 and at least one ventilation port 601 penetrating the annular protrusion 610 are provided on the side of the third sealing member 600 facing the liquid storage portion 320, that is, on the bottom side of the third sealing member 600. One end of the ventilation port 601 penetrates the inner peripheral wall of the annular protrusion 610, and the other end penetrates the outer peripheral wall of the annular protrusion 610.

The third sealing member 600 may be provided with a plurality of annular protrusions 610 which are sequentially sleeved from the inside to the outside, and each annular protrusion 610 is provided with a plurality of ventilation ports 601, so that the third sealing member 600 can provide a good ventilation effect.

Please continue to refer to Figure 8.

Since the atomized aerosol is higher in temperature than the environment or the airway and has a certain humidity, condensation is easily formed on the inner peripheral surface of the first inner wall 140, and the condensation flows downward along the first inner wall 140. In order to prevent the condensation from flowing back from the air inlet channel 102 to the controller 20 and causing the airflow sensor to start or fail automatically, the atomizer 10 can be provided with a first liquid absorbent member 710 in the air inlet channel 102 to absorb the refluxed condensation. The first liquid absorbent member 710 can be made of materials such as cotton, sponge or non-woven fabric with good absorbency.

In some embodiments, the first liquid absorbent member 710 is interference-fitted in the air inlet channel 102. The diameter of the air inlet channel 102 may be gradually reduced along the air inlet direction, that is, the inner diameter of the bottom end of the first inner wall 140 is gradually reduced along the air inlet direction, so that the first liquid absorbent member 710 can be installed in the air inlet channel 102 from bottom to top to achieve interference fitting. The air intake passage 102 is provided with a through hole coaxially arranged with the air intake passage 102 to ensure smooth air intake.

In addition, condensate may also be formed on the surface of the second inner wall 210 exposed to the air outlet channel 2102. To prevent condensate from leaking out of the gap between the first shell 100 and the second shell 200, a second liquid absorbing member 720 may be disposed around the second sealing member 500.

Specifically, the second sealing member 500 may include a first portion 520 and a second portion 530 extending from one end of the first portion 520 away from the bottom wall 120. The first portion 520 abuts against the first outer wall 130 and may be interference fit with the first outer wall 130. For example, the first portion 520 is sleeved with a sealing ring 510 that is interference fit with the first outer wall 130. The second portion 530 is spaced apart from the first outer wall 130, and the second liquid absorbent member 720 is disposed between the second portion 530 and the first outer wall 130.

In some embodiments, a third liquid absorbing member 730 is further provided on the side of the third sealing member 600 facing away from the bottom wall 120, that is, on the top side thereof. The third liquid absorbing member 730 abuts against the bottom end of the second inner wall 210, and the third liquid absorbing member 730 has a vent hole 7301 coaxially arranged with the gas outlet channel 2102. The caliber of the vent hole 7301 can be larger than the inlet caliber of the gas outlet channel 2102, so that the aerosol can be input from a larger space to a smaller space, which is beneficial to improve the fullness of the aerosol output by the atomizer 10.

Optionally, the second inner wall 210 and the second outer wall 220 are spaced apart, that is, a cavity is formed between the second inner wall 210 and the second outer wall 220 to reduce the manufacturing cost of the second shell 200. The outer peripheral wall of the third liquid-absorbing member 730 may contact the second outer wall 220 to block the cavity.

Please refer to FIG. 10 and FIG. 11 , FIG. 10 is a schematic cross-sectional view of the atomizer provided in some embodiments of the present application, and FIG. 11 is a schematic cross-sectional view of a portion of the atomizer in the embodiment of FIG. 10 .

In some embodiments, the liquid storage portion 320 protrudes from the outer peripheral wall of the liquid guide portion 310, and a first positioning portion 350 having an inclined surface is formed at the connection between the liquid storage portion 320 and the liquid guide portion 310. A second positioning portion 540 adapted to the first positioning portion 350 is protruded from the bottom end of the inner peripheral wall of the second sealing member 500. The first positioning portion 350 abuts against the second positioning portion 540 to cooperate in positioning the liquid guide member 300 and the second sealing member 500 during assembly.

During assembly, the liquid guiding member 300 can be installed in the second sealing member 500 from top to bottom until the first positioning portion 350 contacts the second positioning portion 540. At this time, the second positioning portion 540 can limit the liquid guiding member 300 from further moving downward, and it is considered that the liquid guiding member 300 has moved to the preset position. The liquid guiding member 300 can be further installed in the first housing 100 after assembling a module with the second sealing member 500. In this assembly process, the relative height between the top of the second sealing member 500 and the first outer wall 130 can be used as a reference value for the installation progress of the liquid guiding member 300.
