Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to an atomizer and an aerosol generation device including the atomizer. Background Technology

[0002] An aerosol generating device is an apparatus for atomizing a liquid matrix to generate an aerosol. An exemplary aerosol generating device exists, comprising an atomizing core for atomizing the liquid matrix and a storage chamber for storing the liquid matrix. However, after the initial injection of the liquid matrix into the storage chamber, a relatively long waiting period is required for the liquid matrix to fully wet the atomizing core. Consequently, when using the aerosol generating device for the first time, the atomizing core is highly susceptible to dry burning due to insufficient wetting of the liquid matrix. Utility Model Content

[0028] In some embodiments, the second sealing plug further includes an open ring with a pressure relief port, the open ring being disposed on the side of the fourth closed ring near the second end. During the process of assembling the second sealing plug into the second injection hole, the open ring elastically deforms between the second substrate and the hole wall of the second injection hole, and a portion of the gas in the storage cavity flows through the pressure relief port into the interval between the open ring and the fourth closed ring.

[0029] In some embodiments, the storage cavity has a proximal end and a distal end disposed opposite to each other, and the atomizing core is disposed adjacent to the distal end;

[0040] The atomizer and aerosol generating device including the atomizer provided in some of the above embodiments include a first sealing plug, a main body having an internal storage cavity, and an atomizing core for atomizing a liquid matrix. The main body has a first injection hole communicating with the storage cavity, which serves as an inlet for injecting the liquid matrix into the storage cavity. The first sealing plug seals the first injection hole after the liquid matrix has been injected into the storage cavity. During insertion into the injection hole, the first sealing plug partially enters the storage cavity, occupying its space and thus forcing a portion of the liquid matrix into the atomizing core. This accelerates the wetting of the atomizing core by the liquid matrix, and while sealing the first injection hole, it also helps to ensure the atomizing core is adequately wetted.

[0063] Please refer to Figure 1 and Figure 2 This application provides an embodiment of an aerosol generating device 100, which includes an atomizer 200 capable of atomizing a liquid matrix to generate an aerosol.

[0064] In some embodiments, reference may be made to Figure 2 and Figure 3 The atomizer 200 includes a main body 1 with a storage chamber 13 and an atomizing core 12 for atomizing a liquid matrix. The storage chamber 111 stores the liquid matrix. The liquid matrix is ​​liquid at room temperature. The liquid matrix may contain a liquid containing tobacco-containing substances with volatile tobacco flavor components, or it may contain a liquid containing non-tobacco substances. The liquid matrix may contain water, medicinal liquid, solvent, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include menthol, peppermint, spearmint oil, various fruit flavor components, etc., but are not limited to these. Flavorings may contain ingredients that can provide the user with various fragrances or flavors. The vitamin mixture may be a mixture containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited to these. The atomizer 200 can be applied to different fields, such as medical and electronic aerosol atomization, depending on the liquid matrix it stores.

[0065] The atomizing core 12 is connected to the storage chamber 13, so that the liquid matrix in the storage chamber 13 can be conducted to the atomizing core 12 and then atomized by the atomizing core 12.

[0066] As an example, the atomizing core 12 includes a liquid-absorbing element 121 and a heating element, with the heating element disposed on the liquid-absorbing element 121. The liquid-absorbing element 121 can be a porous body used to guide the liquid matrix into the atomization range of the heating element. The heating element is used to heat and atomize the liquid matrix, thereby generating a sol. The porous body can be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous body can be porous ceramic or porous metal; this application does not limit the structure and composition of the porous body. Therefore, before the heating element atomizes the liquid matrix, the liquid matrix needs to be fully wetted into the liquid-absorbing element to prevent the heating element from dry burning.

[0067] As an example, the atomizing core 12 includes an ultrasonic element capable of generating ultrasonic waves, which can use ultrasonic waves to atomize a liquid matrix into an aerosol.

[0068] Of course, the atomizing core 12 may also include other elements that enable the liquid matrix to be atomized.

[0069] In some embodiments, the atomizer 200 is configured as an electrically operated atomizer, wherein the energy for atomizing the liquid matrix is ​​derived from electrical energy. Further, the aerosol generating device 100 also includes a power supply assembly 2 for providing electrical power to the atomizing coil 12 to atomize the liquid matrix. The power supply assembly 2 may include a power source configured to provide electrical power to the atomizer 200. The power source may include any suitable battery, such as a lithium battery, a disposable battery, or a rechargeable battery. The power supply assembly 2 may also include a controller that can protect the power source or control the power output of the power source. The controller may include at least one microprocessor or microcontroller. The microprocessor or microcontroller may include a gate array, or may include a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor. Furthermore, those skilled in the art will understand that the controller may include another type of hardware.

[0070] In some embodiments, reference may be made to Figure 2 and Figure 3 The main body 1 also includes a conduit 14, which is in fluid communication with the atomizing core 12 and can export the aerosol generated by the atomizing liquid matrix by the atomizing core 12 to the main body 1.

[0071] In such Figure 2 In the illustrated embodiment, at least a portion of the conduit 14 is located in the storage cavity 13, and at least a portion of the atomizing core 12 may be disposed in the conduit 14.

[0072] Furthermore, a liquid guiding hole is provided on the wall of the conduit 14, which can connect the storage cavity 13 and the atomizing core 12. The liquid matrix in the storage cavity 13 can be guided into the atomizing core 12 by the liquid guiding hole.

[0073] In some embodiments, reference may be made to Figure 2 and Figure 3 The conduit 14 includes a first conduit 141 and a second conduit 142 disposed around the first conduit 141. A liquid guiding element 15 is disposed between the first conduit 141 and the second conduit 142. A second liquid guiding hole 1421 is formed on the second conduit 142, which is used to guide the liquid matrix in the storage cavity 13 to the liquid guiding element 15 for absorption by the liquid guiding element 15. The liquid guiding element 15 may be, but is not limited to, cotton fiber, polypropylene fiber, polyester fiber, nylon fiber, porous ceramic material, polymer fiber, or various combinations of the above materials.

[0074] The atomizing core 12 is held within the first conduit 141 and is in communication with the liquid guiding element 15, thereby enabling the atomizing core 12 to absorb at least a portion of the liquid matrix on the liquid guiding element 15. Therefore, the liquid matrix stored in the storage cavity 13 can be guided to the liquid guiding element 15 through the second liquid guiding hole 1421 on the second conduit 142, and then conducted to the atomizing core 12 through the liquid guiding element 15. Consequently, before the liquid matrix is ​​conducted to the atomizing core 12, the liquid guiding element 15 needs to be wetted with the liquid matrix.

[0075] In some embodiments, reference may be made to Figure 3 The first conduit 141 includes a first part 1411 and a second part 1412 that are independent of each other. The atomizing core 12 is held in the first part 1411 so that the atomizing core 12 and the first part 1411 can be assembled as a whole into the inside of the liquid guiding element 15.

[0076] Furthermore, a first liquid guiding hole is provided on the first part 1411. The first liquid guiding hole is used to connect the liquid guiding element 15 and the liquid absorption element 121 of the atomizing core 12, so that at least part of the liquid matrix absorbed by the liquid guiding element 15 can be conducted to the liquid absorption element 121.

[0077] In other embodiments (not shown), the atomizer 200 further includes a compartment in which the atomizing core 12 is disposed. The compartment is connected to the storage chamber 13 via a liquid channel, so that the liquid matrix in the storage chamber 13 can be transferred to the atomizing core 12. The compartment is in fluid communication with the conduit 14, so that the aerosol formed in the compartment can be discharged by the conduit 14.

[0078] In some embodiments, reference may be made to Figure 2 The main body 1 also includes a housing 11, which can define at least a portion of the boundary of the storage cavity 13.

[0079] In some embodiments, the atomizer 200 further includes a mouthpiece 3 with an air inlet for discharging the aerosol generated by the atomizer 200. When held in the mouth by a user, the air inlet is positioned toward the user's oral cavity, so that the user can inhale the aerosol generated by the atomizer 200 through the mouthpiece 3.

[0080] In some embodiments, the suction nozzle 3 is a component of the main body 1. The suction nozzle 3 may be integrally formed with the housing 11, or the suction nozzle 3 may be attached to the housing 11.

[0081] In some embodiments, reference may be made to Figure 2The atomizer 200 also includes a base 4, which is connected to the housing 11 and defines a portion of the boundary of the storage cavity 13. Specifically, the storage cavity 13 has a proximal end and a distal end disposed opposite to each other, the mouthpiece 3 is disposed adjacent to the proximal end of the storage cavity 13, and the base 4 defines at least a portion of the boundary of the distal end of the storage cavity 13. Preferably, see [reference needed]. Figure 2 The liquid guiding hole or the second liquid guiding hole 1421 is disposed adjacent to the distal end of the storage cavity 13 or adjacent to the base 4. In some embodiments, reference can be made to Figure 8 The maximum distance between the liquid guiding hole or the second liquid guiding hole 1421 and the far end of the storage cavity 13 is H, which can be less than or equal to 2 mm.

[0082] In such Figure 2 In the illustrated embodiment, one end of the conduit 14 can be connected to the base 4. The conduit 14 can extend longitudinally.

[0083] In some embodiments, reference may be made to Figure 3 The atomizer 200 also includes an electrode 5 for electrical connection with the power supply assembly 2, the electrode 5 being held on the base 4.

[0084] In some embodiments, the atomizer 200 is configured to be removably connected to the power supply assembly 2. When the atomizer 200 is connected to the power supply assembly 2, the atomizer coil 12 can be electrically connected to the power source via the electrode 5. When the atomizer 200 is removed from the power supply assembly 2, the electrical connection between the atomizer coil 12 and the power source is released.

[0085] As an example, the atomizer 200 and the power supply assembly 2 are removably connected via magnetic attraction. Furthermore, the atomizer 200 includes a magnetic element 6, which is configured to attract ferromagnetic metals or be attracted by a magnet. The power supply assembly 2 is provided with a mating part that can be magnetically attracted to the magnetic element 6.

[0086] The magnetic component 6 can be held on the base 4.

[0087] In some embodiments, reference may be made to Figure 2 The base 4 includes a seal 41 and a bottom cover 42. The seal 41 connects the housing 11 and the bottom cover 42 and provides a seal between the housing 11 and the bottom cover 42 to prevent leakage of the liquid matrix in the storage cavity 13.

[0088] The seal 41 can be laid flat to define at least a portion of the boundary of the distal end of the storage cavity 13.

[0089] In some embodiments, reference may be made to Figure 5 An air inlet 43 is provided on the base 4, which is used to guide the outside air to the atomizing core 12.

[0090] In some embodiments, reference may be made to Figure 3 and Figure 6 The atomizer 200 is configured to be injected with a liquid matrix to replenish the liquid matrix in the storage chamber 13. Accordingly, the main body 1 has a first injection port 161 communicating with the storage chamber 13, which serves as an inlet for injecting the liquid matrix into the storage chamber 13. When the first injection port 161 is open, the liquid matrix can be injected into the storage chamber 13 through the first injection port 161.

[0091] The atomizer 200 also includes a first sealing plug 7, at least partially configured to seal the first injection port 161 by means of being disposed in the first injection port 161. More specifically, the first sealing plug 7 is used to seal the first injection port 161 after a liquid matrix has been injected into the storage chamber 13.

[0092] During the process of setting the first sealing plug 7 in the first injection hole 161, it can increase the hydraulic pressure of the liquid matrix in the storage cavity 13, thereby accelerating the speed at which the liquid matrix wets the atomizing core 12 and / or the liquid guiding element 15.

[0093] For example, during the insertion of the first sealing plug 7 into the first injection hole 161, a portion of the first sealing plug 7 enters the storage cavity 13, occupying its space and thus forcing a portion of the liquid matrix into the atomizing core 12. During insertion into the first injection hole 161, the first sealing plug 7 can directly compress the liquid matrix by contacting it, or it can indirectly compress the liquid matrix by compressing the gas in the storage cavity 13, thereby increasing the gas pressure within the storage cavity 13. Of course, during the insertion of the first sealing plug 7 into the first injection hole 161, the liquid matrix in the storage cavity 13 can be simultaneously compressed both directly and indirectly by the first sealing plug 7. Therefore, during the insertion of the first sealing plug 7 into the first injection hole 161, the speed at which the liquid matrix wets the atomizing core 12 and / or the liquid guiding element 15 can be accelerated.

[0094] In some embodiments, the body 1 further includes a transparent portion for defining at least a portion of the boundary of the storage cavity 13, allowing observation of the liquid level of the liquid matrix. When the liquid matrix is ​​injected into the storage cavity 13, the liquid level of the injected liquid matrix can be observed through the transparent portion to prevent excessive injection of liquid matrix leading to leakage when sealing the injection hole, and to prevent insufficient injection of liquid matrix. Further, a window is provided on the housing 11, and the transparent portion is embedded in the window. Alternatively, the housing 11 includes a transparent portion. Alternatively, the housing 11 is made of a transparent material, thus the housing 11 is a transparent portion.

[0095] In some embodiments, reference may be made to Figure 8The main body 1 also includes a first injection line 17 for indicating the liquid level of the liquid matrix, and a first sealing plug 7 includes a first end 711 disposed toward the storage cavity 13. When the first sealing plug 7 is fully received in the first injection hole 161, the first end 711 is disposed adjacent to or flush with the first injection line.

[0096] The phrase "the first end 711 is positioned adjacent to the first injection line 17" means that the distance X between the end face of the first end 711 and the first injection line 17 is less than or equal to 5 mm. Preferably, "the first end 711 is positioned adjacent to the first injection line 17" means that the distance X between the end face of the first end 711 and the first injection line 17 is less than or equal to 2 mm. More preferably, "the first end 711 is positioned adjacent to the first injection line 17" means that the distance X between the end face of the first end 711 and the first injection line 17 is less than or equal to 1 mm; for example, the distance X between the first end 711 and the first injection line 17 can be approximately 0.6 mm.

[0097] It should be noted that the first end 711 is disposed adjacent to the first injection line 17, which may include the end face of the first end 711 being higher than the first injection line 17, so that when the liquid matrix injected through the first injection hole 161 reaches the first injection line 17, the end face of the first end 711 is outside the liquid level of the liquid matrix and is not submerged by the liquid matrix; or, the first end 711 is disposed adjacent to the first injection line 17, which may include the end face of the first end 77 extending beyond the first injection line 17, so that when the liquid matrix injected through the first injection hole 161 reaches the first injection line 17, the end face of the first end 711 is submerged by the liquid matrix.

[0098] When injecting liquid into the storage cavity 13 through the first injection hole 161, the first injection line 17 can be used as a reference line, and the injection can be stopped when the liquid level in the storage cavity 13 reaches the first injection line 17. By setting the first injection line 17, it is possible to prevent the liquid level from exceeding the first injection line 17 when injecting liquid through the first injection hole 161, thereby preventing the injection of excessive liquid matrix into the storage cavity 13.

[0099] The first injection line 17 may include an indicator line or a scale line disposed on the transparent portion. The first injection line 17 may include a boundary line between two adjacent components constituting the housing 11. The first injection line 17 may include the end face of a component disposed inside the storage cavity 13 and corresponding to the transparent portion, or the first injection line 17 may include an indicator line, scale line, or boundary line disposed inside the storage cavity 13 and corresponding to the transparent portion.

[0100] In some embodiments, when the orientation of the main body 1 is adjusted so that a liquid matrix can be injected into the storage cavity 13 through the first injection hole 161, the first injection line 17 is positioned higher than the liquid guide hole or the second liquid guide hole 1421. This helps to ensure that the liquid matrix submerges the liquid guide hole or the second liquid guide hole 1421 when injecting the liquid matrix into the storage cavity 13 through the first injection hole 161, and helps to wet the liquid guide element 15 and / or the atomizing core 12 during the injection process.

[0101] Furthermore, when adjusting the posture of the main body 1 so that the liquid matrix can be injected into the storage cavity 13 through the first injection hole 161, the first injection line 17 is positioned higher than the atomizing core 12. This helps promote the adsorption of the liquid matrix by the liquid guiding element 15 and / or the atomizing core 12 when the liquid matrix is ​​injected into the storage cavity 13 through the first injection hole 161, thereby accelerating the wetting of the liquid guiding element 15 and / or the atomizing core 12 by the liquid matrix.

[0102] In some embodiments, the port of the first injection hole 161 facing the storage cavity 13 is flush with the first injection line 17. Thus, after the first sealing plug 7 is disposed in the first injection hole 161, the end face of the first end 711 of the first sealing plug 7 can be flush with the port of the first injection hole 161 facing the storage cavity 13, or the end face of the first end 711 of the first sealing plug 7 can be disposed adjacent to the port of the first injection hole 161 facing the storage cavity 13.

[0103] For example, when the main body 1 includes a first tubular body 16 for defining at least a portion of the boundary of the first injection hole 161, and the end of the first tubular body 16 opening toward the storage cavity 13 is located in the storage cavity 13, the first injection line 17 may include the end of the first tubular body 16 opening toward the storage cavity 13, or the first injection line 17 may be flush with the end of the first tubular body 16 opening toward the storage cavity 13. Thus, the end face of the first end 711 of the first sealing plug 7 may be flush with the end of the first tubular body 16 opening toward the storage cavity 13, or the end face of the first end 711 of the first sealing plug 7 may be disposed adjacent to the end of the first tubular body 16 opening toward the storage cavity 13.

[0104] When the end face of the first end 711 of the first sealing plug 7 is disposed near the end of the first tubular body 16 opening toward the storage cavity 13, the first end 711 may be located inside the first tubular body 16, so that the first end 711 does not protrude from the first tubular body 16 or the first injection hole 161. Alternatively, when the end face of the first end 711 of the first sealing plug 7 is disposed near the end of the first tubular body 16 opening toward the storage cavity 13, the first end 711 may protrude from the first tubular body 16 or the first injection hole 161, so that a portion of the first sealing plug 7 is located in the first tubular body 16 or the first injection hole 161 to seal the first tubular body 16 or the first injection hole 161, and the first end 711 passes through the first tubular body 16 or the first injection hole 161 and is located in the storage cavity 13.

[0105] In some embodiments, the first injection line 17 is not flush with the port of the first injection hole 161 that faces the storage cavity 13.

[0106] As an example, the first injection line 17 is located between the liquid guide hole or the second liquid guide hole 1421 and the first injection hole 161. So when liquid matrix is ​​injected into the storage cavity 13 through the first injection hole 161, the liquid matrix level reaches the first injection line 17 and is higher than the liquid guide hole or the second liquid guide hole 1421. Thus, the liquid matrix can submerge the liquid guide hole or the second liquid guide hole 1421, and can prevent the liquid matrix level from submerging the port of the first injection hole 161 facing the storage cavity 13. This can both promote the liquid matrix to wet the liquid guide element 15 and / or the atomizing core 12, and prevent the liquid matrix from overflowing through the first injection hole 161 during the process of the first sealing plug 7 being placed in the first injection hole 161.

[0107] Furthermore, the first injection line 17 is located between the atomizing core 12 and the first injection hole 161.

[0108] Furthermore, after the first sealing plug 7 is installed in the first injection hole 161, the end face of the first end 711 is located between the first injection line 17 and the first injection hole 161. Thus, after the liquid matrix is ​​injected into the storage cavity 13 through the first injection hole 161 so that the liquid level of the liquid matrix reaches the first injection line 17, the first sealing plug 7 is installed in the first injection hole 161. Part of the first sealing plug 7 is located in the first injection hole 161 to seal the first injection hole 161, but the end face of the first end 711 of the first sealing plug 7 protrudes from the first injection hole 161. Thus, the end face of the first end 711 is in the storage cavity 13 and located outside the first injection hole 161. At the same time, the end face of the first end 711 is higher than the liquid level or the first injection line 17, so that the end face of the first end 711 is not submerged in the liquid matrix.

[0109] As an example, after the first sealing plug 7 is disposed in the first injection hole 161, the first injection line 17 is located between the end face of the first end 711 and the first injection hole 161. Thus, a portion of the first sealing plug 7 is located in the first injection hole 161 to seal the first injection hole 161, but the end face of the first end 711 of the first sealing plug 7 protrudes from the first injection hole 161, so that the end face of the first end 711 is in the storage cavity 13 and located outside the first injection hole 161, while the end face of the first end 711 is immersed in the liquid matrix.

[0110] In some embodiments, reference may be made to Figure 8 The first sealing plug 7 is configured with a preset length such that when the first sealing plug 7 is fully received in the first injection hole 161, the end face of the first end 711 extends beyond the first injection line 17, thereby allowing the end face of the first end 711 to be submerged in the liquid matrix. Compared to when the first sealing plug 7 is fully received in the first injection hole 161, the end face of the first end 711 is higher than the first injection line 17 and thus not submerged in the liquid matrix, the submersion of the end face of the first end 711 in the liquid matrix can accelerate the speed at which the liquid matrix in the storage cavity 13 is forced into the atomizing core 12, thereby more effectively shortening the time for the atomizing core 12 to be fully wetted, and helping the atomizing core 12 to be more fully wetted when the first sealing plug 7 is fully received in the first injection hole 161.

[0111] Furthermore, after the first sealing plug 7 is installed in the first injection hole 161, the distance X between the end face of the first end 711 and the first injection line 17 is less than or equal to 5 mm, that is, the end face of the first end 711 can be submerged in the liquid matrix by at most 5 mm. Alternatively, after the first sealing plug 7 is installed in the first injection hole 161, the space occupied by the first sealing plug 7 in the storage cavity 13 is less than or equal to 0.2 ml.

[0112] When the atomizing core 12 includes a liquid absorption element 121 and a heating element, the liquid absorption element 121 typically needs to absorb 0.2ml-0.5ml of liquid matrix to be sufficiently wetted. If too much liquid matrix is ​​forced into the liquid absorption element 121 in the storage cavity 13, it will cause the liquid matrix to leak through the atomizing core 12. After the first sealing plug 7 is set in the first injection hole 161, the distance between the end face of the first end 711 and the first injection line 17 is less than or equal to 5mm, or the space occupied by the first sealing plug 7 in the storage cavity 13 is less than or equal to 0.2ml. This can prevent the first sealing plug 7 from occupying too much space in the storage cavity 13, thereby preventing excessive liquid matrix from being forced into the atomizing core 12 during the process of the first sealing plug 7 being set in the first injection hole 161, and then the part of the liquid matrix forced into the atomizing core 12 will leak through the atomizing core 12.

[0113] In some embodiments, reference may be made to Figure 1After the first sealing plug 7 is installed in the first injection hole 161, at least a portion of the first sealing plug 7 extends into the storage cavity 13. Furthermore, after the first sealing plug 7 is installed in the first injection hole 161, the length L1 of the first sealing plug 7 extending into the storage cavity 13 is greater than or equal to 8 mm. This allows for the compression of a larger volume of gas in the storage cavity 13 during the installation of the first sealing plug 7 into the first injection hole 161, thereby significantly increasing the gas pressure in the storage cavity 13 and thus compressing the liquid matrix in the sealed space. Even during the installation of the first sealing plug 7 into the first injection hole 161, the first sealing plug 7 can directly contact the liquid matrix, thus acting like a piston to push the liquid matrix, significantly increasing the hydraulic pressure of the liquid matrix at the liquid guide hole or the second liquid guide hole 1421. Furthermore, during the installation of the first sealing plug 7 into the first injection hole 161, it can promote the wetting of the liquid guide element 15 and / or the atomizing core 12 by the liquid matrix.

[0114] Preferably, the length L1 of the first sealing plug 7 extending into the storage cavity 13 is greater than or equal to 10 mm, for example, the length L1 of the first sealing plug 7 extending into the storage cavity 13 can be about 12 mm. This is to allow for greater compression of the liquid matrix in the storage cavity 13 during the process of assembling the first sealing plug 7 into the first injection hole 161.

[0115] In some embodiments, reference may be made to Figure 2 The main body 1 includes a first tubular body 16 that defines at least a portion of the boundary of the first injection hole 161, such that at least a portion of the wall of the first injection hole 161 is the inner wall of the first tubular body 16. The first tubular body 16 extends from the first wall 111 of the housing 11 toward the storage cavity 13. At least a portion of the first sealing plug 7 passes through the first wall 111 of the housing 11 and is held in the first tubular body 16.

[0116] Because the first sealing plug 7 has a relatively large length, and the process of assembling the first sealing plug 7 into the first injection hole 161 significantly increases the gas pressure and liquid matrix hydraulic pressure in the storage cavity 13, the sealing requirements of the first sealing plug 7 on the first injection hole 161 will increase. Otherwise, gas and / or liquid in the storage cavity 13 will depressurize through the first injection hole 161 during the assembly of the first sealing plug 7 into the first injection hole 161. Increasing the depth of the first injection hole 161 to accommodate the relatively long first sealing plug 7 helps to improve the sealing effect of the first sealing plug 7 on the first injection hole 161. The first tubular body 16 helps to increase the depth of the first injection hole 161, and the length of the first tubular body 16 is positively correlated with the depth of the first injection hole 161. This allows the first injection hole 161 to have a greater depth without increasing the wall thickness of the first wall 111 of the housing 11, which is beneficial for reducing the volume of the atomizer 200 or increasing the volume of the storage cavity 13.

[0117] In some embodiments, reference may be made to Figure 2 The length of the first sealing plug 7 extending into the storage cavity 13 is greater than the length of the first tubular body 16, so that the first end 711 of the first sealing plug 7 is located outside the first tubular body 16 and the first injection hole 161 in the storage cavity 13.

[0118] In some embodiments, reference may be made to Figure 2 and Figure 4 The first sealing plug 7 is provided with a stop part 72. The main body 1 is configured to block the stop part 72 from entering the first injection hole 161, so as to prevent the first sealing plug 7 from passing through the first injection hole 161 and falling into the storage cavity 13 during the process of assembling the first sealing plug 7 into the first injection hole 161, thereby opening the first injection hole 161.

[0119] The stop portion 72 is disposed away from the first end 711, and when the first sealing plug 7 seals the first injection hole 161, the stop portion 72 can be located outside the storage cavity 13.

[0120] Furthermore, a retaining groove 112 communicating with the first injection hole 161 is provided on the first wall 111 of the housing 11. A shoulder 113 connecting the circumferential sidewall of the retaining groove 112 and the first injection hole 161 is provided. When the first sealing plug 7 seals the first injection hole 161, the shoulder 113 can interfere with the stop portion 72 to prevent the stop portion 72 of the first sealing plug 7 from entering the first injection hole 161. At least a portion of the end of the first tubular body 16 opposite to the storage cavity 13 may form this shoulder 113. Figure 2In the illustrated embodiment, the inner diameter of the retaining groove 112 is larger than the inner diameter of the first injection hole 161, thereby creating the shoulder 113 between the retaining groove 112 and the first injection hole 161. Figure 4 In the illustrated embodiment, the first sealing plug 7 includes a first base 71 connected to or integrally formed with the stop portion 72. The cross-sectional area of ​​the first base 71 is smaller than the cross-sectional area of ​​the stop portion 72, or the radial dimension of the first base 71 along a certain direction is smaller than the radial dimension of the stop portion 72 along the same direction, thereby forming a step-like structure between the first base 71 and the stop portion 72. The first base 71 can be fitted into the first injection hole 161.

[0121] In some embodiments, reference may be made to Figure 1 The inner diameter D1 of the first injection hole 161 is greater than or equal to 5.5 mm. The inner diameter D1 of the first injection hole 161 is directly proportional to the cross-sectional area of ​​the hole. The larger the cross-sectional area of ​​the hole, the greater the volume of air that can be compressed in the storage cavity 13 during the process of assembling the first sealing plug 7 into the first injection hole 161. Alternatively, the first sealing plug 7 can directly act on the liquid matrix. The larger the cross-sectional area of ​​the hole, the greater the hydraulic pressure of the liquid matrix during the process of assembling the first sealing plug 7 into the first injection hole 161. The inner diameter D1 of the first injection hole 161 refers to the minimum distance between the two sides of the hole. For example, when the shape of the first injection hole 161 is rectangular, the shorter side of the rectangle is the inner diameter D1 of the first injection hole 161. When the shape of the first injection hole 161 is circular, the inner diameter D1 of the first injection hole 161 refers to the diameter of the circle.

[0122] Preferably, the inner diameter D1 of the first injection hole 161 is greater than or equal to 6.5 mm, for example, the inner diameter D1 of the first injection hole 161 can be about 7 mm. This is to increase the air pressure and hydraulic pressure of the liquid matrix in the storage cavity 13 to a greater extent during the process of assembling the first sealing plug 7 into the first injection hole 161.

[0123] In some embodiments, reference may be made to Figure 4 The first sealing plug 7 includes a first base 71 and a first closing ring 73. The first closing ring 73 provides a seal between the first base 71 and the wall of the first injection hole 161. The first base 71 includes a first end 711 facing the storage cavity 13. The first closing ring 73 is disposed adjacent to the first end 711, or the distance L2 between the end faces of the first closing ring 73 and the first end 711 is less than or equal to 3 mm. It should be noted that the closing ring described herein is a closed annulus that can provide a 360° seal between the corresponding base and the wall of the corresponding injection hole to prevent the liquid matrix from flowing to the side of the closing ring away from the storage cavity 13.

[0124] The closer the first closed ring 73 is to the end face of the first end 711, the greater the degree to which the first sealing plug 7 compresses the liquid matrix in the storage cavity 13 during the process of assembling the first sealing plug 7 into the first injection hole 161.

[0125] Preferably, the distance between the first closed loop 73 and the first end 711 is less than or equal to 2 mm.

[0126] When the first sealing plug 7 seals the first injection hole 161, the first closing ring 73 is located inside the first tubular body 16. Preferably, the distance between the first closing ring 73 and the end face of the first tubular body 16 facing the storage cavity 13 is less than or equal to 2 mm. For example, the distance between the first closing ring 73 and the end face of the first tubular body 16 facing the storage cavity 13 can be approximately 1 mm. Furthermore, the first closing ring 73 and the end face of the first tubular body 16 facing the storage cavity 13 are flush.

[0127] In some embodiments, reference may be made to Figure 4 The first sealing plug 7 also includes a second closing ring 74 for providing a seal between the first base 71 and the wall of the first injection hole 161, the second closing ring 74 being located on the side of the first closing ring 73 opposite to the first end 711.

[0128] During the process of assembling the first sealing plug 7 into the first injection hole 161, the gas pressure and / or hydraulic pressure in the storage cavity 13 increase as the first sealing plug 7 extends into the first injection hole 161 and / or the storage cavity 13. The second closing ring 74 can prevent at least part of the gas or liquid that is depressurized between the first closing ring 73 and the hole wall of the first injection hole 161 from overflowing along the first injection hole 161 to the side of the second closing ring 74 away from the storage cavity 13, thereby helping to improve the sealing effect of the first sealing plug 7 on the first injection hole 161 and prevent the liquid matrix from leaking through the first injection hole 161.

[0129] Furthermore, the distance L3 between the first closed ring 73 and the second closed ring 74 is less than or equal to 0.5 mm; or, the distance L3 between the first closed ring 73 and the second closed ring 74 is less than or equal to the distance L2 between the first end 711 and the first closed ring 73. Thus, when the first sealing plug 7 seals the first injection hole 161, there is a small interval between the first closed ring 73 and the second closed ring 74. When the storage cavity 13 exceeds the sealing limit of the first closed ring 73 due to excessive air pressure and / or hydraulic pressure, and thus depressurizes through the first closed ring 73, the gas and / or liquid overflowing towards the side of the first closed ring 73 away from the storage cavity 13 is retained within this small interval in the first injection hole 161. Therefore, even if the gas and / or liquid in the storage cavity 13 depressurizes out of the first closed ring 73, the amount of depressurization is very small, allowing the storage cavity 13 to continue to maintain a high air pressure and hydraulic pressure, thereby allowing the liquid matrix to continue to maintain a high wetting speed of the liquid guiding element 15 and / or atomizing core 12. In other words, the first closed ring 73 and the second closed ring 74 cooperate with each other to not only seal the gas and / or liquid overflowing from the first closed ring 73 in the first injection hole 161 to prevent leakage, but also to reduce the amount of gas and / or liquid in the storage cavity 13 entering the first injection hole 161.

[0130] In some embodiments, reference may be made to Figure 4 The first sealing plug 7 further includes a second closing ring 74 and a third closing ring 75, both used to provide a seal between the first substrate 71 and the wall of the first injection hole 161. The second closing ring 74 and the third closing ring 75 are both located on the side of the first closing ring 73 opposite to the first end 711, and the second closing ring 74 is located between the first closing ring 73 and the third closing ring 75. The first closing ring 73, the second closing ring 74, and the third closing ring 75 enable the first sealing plug 7 to provide at least a triple seal to the first injection hole 161, thereby improving the sealing effect of the first injection hole 161 and preventing gas and / or liquid in the storage cavity 13 from flowing out of the first injection hole 161.

[0131] Understandably, the more closed rings are provided between the first substrate 71 and the wall of the first injection hole 161, the better the sealing effect of the first sealing plug 7 on the first injection hole 161, and the more stable the first sealing plug 7 remains in the first injection hole 161. However, the air pressure and / or hydraulic pressure in the storage cavity 13 will increase as the first sealing plug 7 is assembled into the first injection hole 161, so the resistance encountered by the first sealing plug 7 in assembling into the first injection hole 161 will also increase as the degree of assembly of the first sealing plug 7 into the first injection hole 161 increases. When the density between the multiple closed rings provided between the first substrate 71 and the wall of the first injection hole 161 is too high, it will also increase the resistance encountered by the first sealing plug 7 in assembling into the first injection hole 161. Based on this, by setting the distance L4 between the second closed ring 74 and the third closed ring 75 to be greater than the distance L3 between the second closed ring 74 and the first closed ring 73, or by setting the distance L4 between the second closed ring 74 and the third closed ring 75 to be greater than or equal to 1 mm, the rate of increase in resistance encountered when assembling the first sealing plug 7 into the first injection hole 161 is slowed down, thereby reducing the difficulty of assembling the first sealing plug 7 into the first injection hole 161. Preferably, the distance L4 between the second closed ring 74 and the third closed ring 75 is greater than or equal to 1.5 mm.

[0132] The first sealing plug 7 may further include a fifth closing ring 76, which is disposed on the side of the third closing ring 75 opposite to the first end 711. The fifth closing ring 75 provides a seal between the first substrate 71 and the wall of the first injection hole 161. The distance between the fifth closing ring 76 and the third closing ring 75 may be greater than or equal to the distance L4 between the second closing ring 74 and the third closing ring 75, or the distance between the fifth closing ring 76 and the third closing ring 75 may be greater than or equal to 1 mm.

[0133] In some embodiments, after the first sealing plug 7 is fitted into the first injection hole 161, the first sealing plug 7 is configured to be non-removable from the first injection hole 161.

[0134] Furthermore, the atomizer 200 is configured such that its storage chamber 13 is empty of liquid matrix when stored before initial use. Therefore, liquid matrix needs to be injected into the storage chamber 13 before the atomizer 200 is used for the first time. When injecting liquid matrix into the storage chamber 13 for the first time, the liquid matrix is ​​injected into the empty storage chamber 13 through the first injection port 161. Furthermore, before the first injection of liquid matrix into the storage chamber 13, the first sealing plug 7 is not fully contained in the first injection port 161 or is not installed in the first injection port 161. It should be noted that when the first sealing plug 7 is not fully contained in the first injection port 161, a portion of the first sealing plug 7 may be located within the first injection port 161, or a portion may be located outside the first injection port 161 for operation to remove the first sealing plug 7 and expose the first injection port 161. When the first sealing plug 7 is fully contained within the first injection hole 161, the first sealing plug 7 seals the first injection hole 161, and the first sealing plug 7 cannot be removed from the first injection hole 161. As described herein, "the first sealing plug 7 is disposed in the first injection hole 161", "the first sealing plug 7 is assembled in the first injection hole 161", and "the first sealing plug 7 is assembled into the first injection hole 161" all refer to "the first sealing plug 7 is fully contained within the first injection hole 161".

[0135] In some embodiments, reference may be made to Figure 2 When the first sealing plug 7 is disposed in the first injection hole 161, the end of the first sealing plug 7 facing away from the storage cavity 13 is fitted into the wall of the first wall 111 of the housing 11 and is flush with the outer surface of the first wall 111. Thus, after the first sealing plug 7 is disposed in the first injection hole 161, the first sealing plug 7 is difficult to operate and therefore difficult for the user to pull out of the first injection hole 161.

[0136] Furthermore, when the first sealing plug 7 is disposed in the first injection hole 161, the stop portion 72 of the first sealing plug 7 is fitted into the wall of the first wall 111, and the outer surface of the stop portion 72 is basically flush with the outer surface of the first wall 111.

[0137] In some embodiments (not shown), a retraction prevention portion is provided on the first end, and the retraction prevention portion can extend out of the first tubular body when the first sealing plug seals the first injection hole. The end of the first tubular body facing the storage cavity or the inner side of the first wall is configured to abut against the retraction prevention portion to prevent the first end from retracting into the first injection hole. Furthermore, when the first sealing plug is disposed in the first injection hole, the retraction prevention portion covers at least a portion of the end of the first tubular body facing the storage cavity and seals the port of the first injection hole facing the storage cavity. This prevents the liquid matrix from entering the first injection hole after the first sealing plug is installed, and further increases the gas pressure and / or hydraulic pressure in the storage cavity.

[0138] In some embodiments, reference may be made to Figure 2The first wall 111 of the housing 11 defines at least a portion of the boundary of the proximal end of the storage cavity 13, or the first injection hole 161 is disposed adjacent to the proximal end of the storage cavity 13.

[0139] In some embodiments, reference may be made to Figure 6 The atomizer 200 also has a second injection port 441 communicating with the storage chamber 13, so that when the second injection port 441 is open, liquid matrix can be injected into the storage chamber 13 through the second injection port 441; a second sealing plug 8 is removably disposed in the second injection port 441. When the second sealing plug 8 is disposed in the second injection port 441, it can seal the second injection port 441 to prevent the liquid matrix from leaking through the second injection port 441. When the second sealing plug 8 is removed from the second injection port 441, the second injection port 441 opens, so the liquid matrix can be injected into the storage chamber 13 through the second injection port 441. Therefore, when the liquid matrix in the storage chamber 13 is insufficient or exhausted, the liquid matrix can be replenished in the storage chamber 13 by opening the second injection port 441. The second injection port 441 is independent of the first injection port 161, and the second sealing plug 8 is also independent of the first sealing plug 7.

[0140] In some embodiments, the inner diameter of the second injection hole 441 is less than or equal to 5.5 mm. Preferably, the inner diameter of the second injection hole 441 is less than or equal to 5 mm, for example, the inner diameter of the second injection hole 441 can be approximately 4.8 mm. By having a smaller inner diameter for the second injection hole 441, the increase in air pressure and / or hydraulic pressure in the storage cavity 13 is reduced during the process of placing the second sealing plug 8 in the second injection hole 441, thereby preventing leakage of the liquid matrix through the liquid guiding element 15 and / or atomizing core 12 due to excessive air pressure and / or hydraulic pressure in the storage cavity 13 during this process.

[0141] In some embodiments, the inner diameter of the second injection hole 441 is less than or equal to the inner diameter D1 of the first injection hole 161. This is to ensure that the increase in air pressure and / or hydraulic pressure in the storage cavity 13 during the process of placing the second sealing plug 8 into the second injection hole 441 is less than the increase during the process of placing the first sealing plug 7 into the first injection hole 161. Alternatively, this ensures that the degree of pressure on the liquid matrix in the storage cavity 13 during the process of placing the second sealing plug 8 into the second injection hole 441 is less than the degree of pressure on the liquid matrix in the storage cavity 13 during the process of placing the first sealing plug 7 into the first injection hole 161. This further prevents leakage of the liquid matrix through the liquid guiding element 15 and / or the atomizing core 12 due to excessive air pressure and / or hydraulic pressure in the storage cavity 13.

[0142] In some embodiments, reference may be made to Figure 7The second sealing plug 8 includes a second base 81 and one or more fourth closing rings 82. The second base 81 includes a second end 811 disposed toward the storage cavity 13. When the second sealing plug 8 is disposed in the second injection hole 441, the fourth closing ring 82 provides a seal between the second base 81 and the hole wall of the second injection hole 441, and the minimum distance between the fourth closing ring 82 and the second end 811 is greater than or equal to 2.5 mm.

[0143] The greater the minimum distance between the fourth closing ring 82 and the second end 811 on the second sealing plug 8, or the greater the minimum distance between the fourth closing ring 82 and the port of the second injection hole 441 facing the storage cavity 13, the less the second sealing plug 8 will compress the gas and / or liquid matrix in the storage cavity 13 during the process of assembling the second sealing plug 8 into the second injection hole 441, and thus the more likely it is to prevent excessive increase in the gas pressure and / or hydraulic pressure of the liquid matrix in the storage cavity 13.

[0144] Preferably, the minimum distance between the fourth closed loop 82 and the second end 811 is greater than or equal to 8 mm, for example, the minimum distance between the fourth closed loop 82 and the second end 811 can be about 5.5 mm.

[0145] In such Figure 7 In the illustrated embodiment, there are multiple fourth closing rings 82, and these rings are arranged sequentially in a direction away from the second end 811. This provides multiple seals to the second injection hole 441 by the second sealing plug 8, thereby improving the sealing effect and increasing the stability of the second sealing plug 8 within the injection hole 441. Furthermore, the spacing between two adjacent fourth closing rings 82 can be greater than or equal to 0.5 mm; for example, the spacing between two adjacent fourth closing rings 82 can be approximately 1 mm. By having a larger spacing between adjacent fourth closing rings 82, the resistance encountered during the assembly of the second sealing plug 8 into the second injection hole 441 is reduced, and the rate of increase in resistance during assembly is slowed.

[0146] In some embodiments, reference may be made to Figure 7 The second sealing plug 8 also includes an open ring 83 with a pressure relief port 84. The open ring 83 is disposed on the side of the fourth closed ring 82 near the second end 811. During the process of assembling the second sealing plug 8 into the second injection hole 441, the open ring 83 elastically deforms between the hole walls of the second base 81 and the second injection hole 441, and part of the gas in the storage cavity 13 flows through the pressure relief port 84 into the interval between the open ring 83 and the fourth closed ring 82.

[0147] It should be noted that the open ring 83 described herein is a non-closed annulus and cannot provide a 360° seal between the corresponding substrate and the wall of the corresponding injection hole. The open ring 83 can be generally C-shaped. The open ring 83 may include multiple protrusions or multiple C-shaped structures spaced apart and arranged in an annular pattern.

[0148] During the process of assembling the second sealing plug 8 into the second injection port 441, some of the gas in the storage cavity 13 flows through the pressure relief port 84 into the interval between the open ring 83 and the fourth closed ring 82, thereby relieving pressure and preventing excessive increase in the gas pressure and / or hydraulic pressure of the liquid matrix in the storage cavity 13. The fourth closed ring 82 prevents the gas and / or liquid that has leaked into the second injection port 441 from leaking out of the second injection port 441.

[0149] In some embodiments, reference may be made to Figure 2 The second injection port 441 is located near the distal end of the storage cavity 13. After the liquid matrix is ​​injected into the storage cavity 13, the atomizer 200 can be stored upright, so that the distal end of the storage cavity 13 is located below the proximal end of the storage cavity 13 in the direction of gravity. When the first injection port 161 is located near the proximal end of the storage cavity 13, if the storage cavity 13 needs to be initially injected, the second sealing plug 8 must first seal the second injection port 441, then the atomizer 200 is upright, and then the liquid matrix is ​​injected into the storage cavity 13 through the first injection port 161, and then the first sealing plug 7 is used to seal the first injection port 161. If the storage cavity 13 needs to be refilled, the atomizer 200 must first be inverted, then the second injection port 441 is opened, and then the liquid matrix is ​​injected into the storage cavity 13 through the second injection port 441, and finally the second sealing plug 8 seals the second injection port 441.

[0150] In some embodiments, reference may be made to Figure 2 The base 4 includes a second tubular body 44 extending from the bottom cover 42 toward the storage cavity 13. The second tubular body 44 can be integrally formed with the bottom cover 42. At least a portion of the second injection hole 441 is formed in the second tubular body 42, and at least a portion of the hole wall of the second injection hole 441 can be the inner wall of the second tubular body 44. Therefore, when the second sealing plug 8 seals the second injection hole 441, at least a portion of the second sealing plug 8 is removably disposed in the second tubular body 44. Figure 2 In the embodiment shown, the second tubular body 44 passes through the seal 41 to communicate with the storage cavity 13.

[0151] The base 4 has a large thickness, which makes the second injection hole 441 have a large length. The arrangement of the second tubular body 44 helps to reduce the thickness of the bottom cover 42, thereby helping to reduce the volume of the atomizer 200 or increase the volume of the storage chamber 13.

[0152] An open ring 83 is provided on the side of the fourth closed ring 82 facing the second end. The open ring 83 can occupy part of the space between the fourth closed ring 82 and the port of the second tubular body 44 facing the storage cavity 13 in the second injection hole 441, thereby reducing the amount of liquid matrix entering the second injection hole 441, which helps to reduce the waste of liquid matrix when the second tubular body 44 has a large length.

[0153] Furthermore, one can refer to Figure 7 The open ring 83 includes a first open ring 831 with a first pressure relief port 841 and a second open ring 832 with a second pressure relief port 842. The first open ring 831 and the second open ring 832 are spaced apart, and the second open ring 832 is located between the first open ring 831 and the fourth closed ring 82. Appropriately increasing the number of open rings 83 can occupy more space between the fourth closed ring 82 and the port of the second tubular body 44 facing the storage cavity 13, thereby further reducing the liquid matrix entering the second injection hole 441.

[0154] The first open ring 831 and the second open ring 832 are arranged adjacent to each other, and the distance between the first open ring 831 and the second open ring 832 can be between 0.3mm and 5mm. Preferably, the distance between the first open ring 831 and the second open ring 832 is between 0.5mm and 2mm, for example, the distance between the first open ring 831 and the second open ring 832 can be about 1mm.

[0155] The second open ring 832 and the fourth closed ring 82 are arranged adjacent to each other, and the distance between the second open ring 832 and the fourth closed ring 82 can be between 0.3mm and 5mm. Preferably, the distance between the second open ring 832 and the fourth closed ring 82 is between 0.5mm and 2mm, for example, the distance between the second open ring 832 and the fourth closed ring 82 can be about 1mm. Of course, the distance between the first open ring 831 and the second open ring 832 can be equal to the distance between the second open ring 832 and the fourth closed ring 82.

[0156] In some embodiments, reference may be made to Figure 5 and Figure 7 The second sealing plug 8 includes an operating part 85 disposed away from the storage cavity 13. The operating part 85 is configured to be operable so that the second sealing plug 8 can be removed from the second injection hole 441. The user can operate the operating part 85 to open the second injection hole 441 and to seal the second injection hole 441 with the second sealing plug 8.

[0157] In some embodiments, the second sealing plug 8 is configured to rotate relative to the second injection port 441 between a first position and a second position, and the operating part 85 is configured to be laterally operated when the second sealing plug 8 is in the first position, thereby driving the second sealing plug 8 to rotate to the second position, and longitudinally operated when the second sealing plug 8 is in the second position, thereby driving the second sealing plug 8 out of the second injection port 441. In other words, to open the second injection port 441, at least two two-step operations are required, namely, first moving the second sealing plug 8 from the first position to the second position, and then driving the second sealing plug 8 out of the second injection port 441. This is to prevent people of age or mental incapacity, such as children, from removing the second sealing plug 8 from the second injection port 441.

[0158] Furthermore, the second injection hole 441 extends longitudinally, and the second sealing plug 8 is configured to be longitudinally fitted into the second injection hole 441 and longitudinally removed from the second injection hole 441.

[0159] In some embodiments, reference may be made to Figure 5 and Figure 6 The main body 1 has a groove 45 with a non-circular outer contour 451. The second injection hole 441 connects to the bottom of the groove 45. The groove 45 includes a groove wall 452 disposed between the outer contour 451 and the second injection hole 441. The operating part 85 is constructed to be non-circular. When the second sealing plug 8 is in the first position, the operating part 85 is embedded in the groove 45, making it inconvenient or difficult to operate the operating part 85 longitudinally. In other words, it is inconvenient or difficult to remove the second sealing plug 8 from the second injection hole 441. Furthermore, when the second sealing plug 8 is in the first position, the long axis of the operating part 85 is parallel to the long axis of the outer contour 451.

[0160] When the operating part 85 and the outer contour 451 are elliptical, the major axis of the operating part 85 is the major axis of the ellipse defined by the operating part 85, and the major axis of the outer contour 451 is the major axis of the ellipse defined by the outer contour 451. When the shape of the operating part 85 and / or the outer contour 451 is neither circular nor elliptical, the major axis of the operating part 85 is the line connecting the two points with the largest distance on the same plane of the operating part 85, and the minor axis of the operating part 85 is the line connecting the two points with the smallest distance on the same plane of the operating part 85; the major axis of the outer contour 451 is the line connecting the two points with the largest distance on the same plane of the outer contour 451, and the minor axis of the outer contour 451 is the line connecting the two points with the smallest distance on the same plane of the outer contour 451.

[0161] During the rotation of the second sealing plug 8 from the first position to the second position, the operating part 85 rotates along the groove wall 452, which increases the distance between the operating part 85 and the second injection hole 441, and makes the long axis of the operating part 85 and the long axis of the outer contour 451 tend to be perpendicular or mutually perpendicular.

[0162] The tank wall 452 may include an arc-shaped wall. The tank wall 452 may include a sloping wall. The tank wall 452 may have a smooth surface. Of course, a guide rail may also be provided on the tank wall 452, so that the operating part 85 can rotate along the guide rail to gradually move away from or gradually move closer to the second liquid inlet 441.

[0163] When the second seal 8 is in the first position, the surface of the operating part 85 facing away from the storage cavity 13 and the surface of the bottom cover 42 facing away from the storage cavity 13 can be flush.

[0164] In some embodiments, reference may be made to Figure 8 The main body 1 also includes a second injection line 18 for defining the liquid level of the liquid matrix when liquid is injected through the second injection hole 441. Further, the second sealing plug 8 includes a second end 811 disposed toward the storage cavity 13. When the second sealing plug 8 is disposed at the second injection hole 441, the second end 811 is flush with the second injection line 18, or when the liquid matrix injected through the second injection hole 441 reaches the second injection line 18, the second end 811 is located outside the liquid level of the liquid matrix and is not submerged by the liquid matrix.

[0165] When injecting liquid into the storage cavity 13 through the second injection hole 441, the second injection line 18 can be used as a reference line, and the injection can be stopped when the liquid level in the storage cavity 13 reaches the second injection line 18. By setting the second injection line 18, it is possible to prevent the liquid level from exceeding the second injection line 18 when injecting liquid through the second injection hole 441, thereby preventing the injection of excessive liquid matrix into the storage cavity 13.

[0166] The second injection line 18 may include an indicator line or scale line disposed on the transparent portion. The second injection line 18 may include a boundary line between two adjacent components constituting the housing 11. The second injection line 18 may include the end of a component disposed inside the storage cavity 13 and corresponding to the transparent portion, or the second injection line 18 may include an indicator line, scale line, or boundary line disposed inside the storage cavity 13 and corresponding to the transparent portion.

[0167] In some embodiments, reference may be made to Figure 8The liquid guide hole on the conduit 14 or the second liquid guide hole 1421 on the second conduit 142 is located between the distal end of the storage cavity 13 and the second injection line 18. In other words, the distance Y between the second injection line 18 and the distal end of the storage cavity 13 is greater than the maximum distance H between the second liquid guide hole 1421 and the distal end of the storage cavity 13. Therefore, when the atomizer 200 is inverted and liquid matrix is ​​injected into the storage cavity 13 through the second injection hole 441 until the liquid matrix reaches the second injection line 18, the liquid guide hole on the conduit 14 or the second liquid guide hole 1421 on the second conduit 142 is not submerged by the liquid matrix in the storage cavity 13. Thus, during the process of assembling the second sealing plug 8 into the second injection hole 441, it is possible to prevent the liquid matrix in the storage cavity 13 from being introduced into the atomizing core 12, thereby preventing the liquid matrix from leaking through the atomizing core 12.

[0168] In some embodiments, after the atomizer 200 is inverted, when the second sealing plug 8 is fully accommodated in the second injection hole 441, the end face of the second end 811 of the second sealing plug 8 is higher than the second injection line 18, so that when the atomizer 200 is inverted, the liquid matrix cannot submerge the second end 811 of the second sealing plug 8, thereby reducing the pressure of the second sealing plug 8 on the liquid matrix in the storage cavity 13.

[0169] Furthermore, you can refer to Figure 8 When the second sealing plug 8 is fully accommodated in the second injection hole 441, the distance between the end face of the second end 811 of the second sealing plug 8 and the second injection line 18 is greater than or equal to the distance Y between the second injection line 18 and the far end of the storage cavity 13, so as to reduce the space occupied by the second sealing plug 8 in the storage cavity 13.

[0170] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
