Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic atomization, and in particular to an electronic atomization device. BACKGROUND

[0002] As a substitute for traditional cigarettes, the electronic atomization device usually comprises an oil cup, a sealing member, an atomization core and a mouthpiece. The oil cup has an atomization cavity, an air outlet channel communicated with the atomization cavity and a liquid storage cavity for storing atomization liquid. The oil cup has an opening communicated with the liquid storage cavity. The sealing member is arranged at the opening of the oil cup. The atomization core is arranged in the atomization cavity and is in fluid communication with the liquid storage cavity. The atomization core is used for heating the atomization liquid to form a smokeable aerosol in the atomization cavity, which leads to the air outlet channel. The mouthpiece cover is arranged at the opening of the oil cup and has a suction port communicated with the air outlet channel.

[0003] In the related art, a single liquid injection hole is arranged on the oil cup or the sealing member when liquid is injected into the liquid storage cavity. After the liquid storage cavity is filled with the atomization liquid, the mouthpiece cover is arranged at the opening of the oil cup. During the liquid injection process, the space in the liquid storage cavity is gradually filled with the atomization liquid. In order to balance the air pressure inside and outside the liquid storage cavity, an air exhaust channel for exhausting the air in the liquid storage cavity must be provided, otherwise the liquid storage cavity cannot be filled with the atomization liquid. When the liquid is injected through the single liquid injection hole, the gap between the liquid injection needle and the hole wall of the liquid injection hole is usually used as the air exhaust channel. In order to seal the liquid injection hole after the liquid injection, a sealing column is usually arranged on the mouthpiece. After the mouthpiece cover is arranged at the opening of the oil cup, the sealing column can be inserted into the liquid injection hole to seal the liquid injection hole. However, during the process of inserting the sealing column into the liquid injection hole, the air pressure in the liquid storage cavity will increase, thereby causing some atomization liquid to be squeezed into the atomization core. When the atomization liquid squeezed into the atomization core exceeds the maximum liquid storage capacity of the atomization core, liquid leakage will occur. In addition, when the gap between the liquid injection needle and the hole wall of the liquid injection hole is used as the air exhaust channel, once the atomization liquid adheres to the liquid injection needle, there is a risk of blocking the air exhaust channel. At this time, in order to reduce the risk of atomization liquid blocking the air exhaust channel, the size of the liquid injection hole is usually increased to have a larger gap between the liquid injection needle and the hole wall of the liquid injection hole. However, after increasing the size of the liquid injection hole, the size of the sealing column for sealing the liquid injection hole also needs to be increased, so that the amount of atomization liquid squeezed into the atomization core when the sealing column is inserted into the liquid injection hole increases, thereby increasing the risk of liquid leakage. CONTENT OF THE UTILITY MODEL

[0004] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application provides an electronic atomization device, which is beneficial to reduce the amount of atomization liquid squeezed into the atomization core during assembly, thereby reducing the risk of liquid leakage.

[0005] According to the electronic atomization device of the first aspect of the present application, the first working position of the movable element is ensured when the nozzle, the sealing element and the movable element are assembled together. During the process of sealing the opening of the liquid storage cavity by the sealing element, the movable element is in the first working position, which limits the relative movement between the nozzle and the sealing element in the longitudinal direction, so that the sealing portion arranged on the nozzle cannot temporarily seal the through hole, thereby allowing air to be discharged through the through hole, which is conducive to reducing the atomization liquid squeezed into the atomization core during assembly. After the sealing element seals the opening of the liquid storage cavity, the movable element is driven by the driving structure to move from the first working position to the second working position to release the limitation, so that the sealing portion arranged on the nozzle can seal the through hole after the sealing element seals the opening of the liquid storage cavity. During the above assembly process, the through hole is only used for air discharge, i.e. the liquid injection needle is not required to cooperate with the through hole for liquid injection. Compared with the prior art, the gap between the liquid injection needle and the inner wall of the through hole is not required to be considered to be blocked by the atomization liquid during liquid injection, so that the size of the through hole can be reduced, thereby being conducive to reducing the atomization liquid squeezed into the atomization core during the process of sealing the through hole by the sealing portion, and further being conducive to reducing the risk of liquid leakage.

[0006] According to the electronic atomization device of the first aspect of the present application, the first working position of the movable element is ensured when the nozzle, the sealing element and the movable element are assembled together.

After the sealing element seals the opening of the liquid storage cavity, the movable element is driven by the driving structure to move from the first working position to the second working position to release the limitation, so that the sealing portion arranged on the nozzle can seal the through hole after the sealing element seals the opening of the liquid storage cavity. During the above assembly process, the through hole is only used for air discharge, i.e. the liquid injection needle is not required to cooperate with the through hole for liquid injection.

[0043] Reference Figures 1 to 12 According to the electronic atomization device of the embodiments of the present application, the shell 100, the suction nozzle assembly, and the driving structure are included.

[0044] Specifically, the inside of the shell 100 has a liquid storage cavity 110 for storing atomized liquid, the liquid storage cavity 110 has an opening 120 at one end of the shell 100 for liquid injection, a nozzle assembly is used to assemble at the opening 120, the nozzle assembly includes a nozzle 210, a sealing member 220 and a movable member 230 assembled as a whole, the sealing member 220 can move longitudinally relative to the nozzle 210, the sealing member 220 is used to block the opening 120 and has a through hole 221 for exhaust, the movable member 230 is movably arranged between the nozzle 210 and the sealing member 220, the movable member 230 has a first working position for limiting the movement of the sealing member 220 longitudinally relative to the nozzle 210 and a second working position for releasing the limitation, the nozzle 210 is provided with a sealing portion 211 for blocking the through hole 221, the sealing portion 211 can block the through hole 221 when the movable member 230 is in the second working position, and a driving structure is arranged in at least one of the shell 100, the nozzle 210 and the sealing member 220, the driving structure is used to drive the movable member 230 to move from the first working position to the second working position when the nozzle assembly is assembled at the opening 120.

[0045] It should be noted that the above-mentioned longitudinal direction is the X direction in the drawing.

[0046] When assembling, liquid is first injected into the liquid storage cavity 110 through the opening 120, after the liquid injection is completed, the nozzle assembly formed by the nozzle 210, the sealing member 220 and the movable member 230 assembled as a whole is assembled at the opening 120, wherein the nozzle 210, the sealing member 220 and the movable member 230 are pre-assembled as a whole to ensure that the movable member 230 is in the first working position. During the process of applying force to the nozzle assembly to make the sealing member 220 block the opening 120, since the movable member 230 is in the first working position, the relative movement of the nozzle 210 and the sealing member 220 in the longitudinal direction can be limited, so that the sealing portion 211 arranged on the nozzle 210 cannot temporarily block the through hole 221, thereby the exhaust can be achieved through the through hole 221, and it is beneficial to reduce the atomized liquid squeezed into the atomizing core during the assembly. During the process of blocking the opening 120 by the sealing member 220, or after the opening 120 is blocked by the sealing member 220, the movable member 230 is driven by the driving structure to move from the first working position to the second working position to release the limitation, so that the sealing portion 211 arranged on the nozzle 210 can block the through hole 221 after the opening 120 is blocked by the sealing member 220. During the above-mentioned assembly process, the through hole 221 is only used for exhaust, i.e. it is not necessary to cooperate with the liquid injection needle to inject liquid through the through hole 221, compared with the prior art, it is not necessary to consider the case that the gap between the liquid injection needle and the inner wall of the through hole 221 is blocked by the atomized liquid during the liquid injection, therefore, the size of the through hole 221 can be reduced, thereby it is beneficial to reduce the atomized liquid squeezed into the atomizing core during the process of blocking the through hole 221 by the sealing portion 211, and it is further beneficial to reduce the risk of liquid leakage.

[0047] It should be noted that in some embodiments, the movable member 230 is movably arranged between the suction nozzle 210 and the sealing member 220 and is movable along a direction intersecting the longitudinal direction.

[0048] Specifically, the movable member 230 is movably arranged between the suction nozzle 210 and the sealing member 220 and is movable along a direction perpendicular to the longitudinal direction. In some embodiments, the electronic atomization device has a first direction and a second direction perpendicular to the longitudinal direction, the first direction and the second direction intersect, the electronic atomization device has a first dimension along the first direction and a second dimension along the second direction, the first dimension is greater than the second dimension, and the driving structure is configured to drive the movable member 230 to move along the first direction to ensure that the movable member 230 has sufficient movement space. In some other embodiments, the driving structure is configured to drive the movable member 230 to move along the second direction, or the first dimension is equal to or less than the second dimension.

[0049] It should be noted that in some embodiments, the movable member 230 can be a sheet structure made of a hard material, such as a metal sheet made of a hard metal material. For example, the metal sheet can be a steel sheet.

[0050] Referring to Figures 1 to 6 In some embodiments, the suction nozzle 210 has a receiving cavity 212, and the sealing member 220 is embedded in the receiving cavity 212.

[0051] Referring to Figures 1 to 7 In some embodiments, the suction nozzle 210 is provided with a first limiting portion 213, the movable member 230 is provided with a first avoiding through hole 2311 for penetrating the first limiting portion 213, and the sealing member 220 is provided with an avoiding groove 222 for inserting the first limiting portion 213. The first limiting portion 213 can penetrate the first avoiding through hole 2311 and be inserted into the avoiding groove 222 when the movable member 230 is in the second working position, and the first limiting portion 213 can abut against the movable member 230 when the movable member 230 is in the first working position. At this time, the first limiting portion 213 is misaligned with the first avoiding through hole 2311 to limit the movement of the sealing member 220 relative to the suction nozzle 210 along the longitudinal direction. The structure is simple and easy to implement.

[0052] Referring to Figures 1 to 6In some embodiments, the through hole 221 comprises an exhaust section 221a away from the liquid storage cavity 110 and a sealing section 221b close to the liquid storage cavity 110, the exhaust section 221a has a larger diameter than the sealing section 221b, and the sealing section 221b is configured to cooperate with the sealing part 211 to seal the through hole 221. During assembly, the sealing part 211 arranged on the suction nozzle 210 is first inserted into the exhaust section 221a, that is, the sealing part 211 does not immediately seal the through hole 221 after being inserted into the through hole 221, but can exhaust through the gap between the sealing part 211 and the hole wall of the exhaust section 221a until the sealing part 211 is inserted into the sealing section 221b to complete the sealing of the through hole 221, thereby facilitating the further reduction of the atomized liquid squeezed into the atomizing core during the process of the sealing part 211 sealing the through hole 221.

[0053] Specifically, the sealing section 221b is configured to be in interference fit with the sealing part 211 to seal the through hole 221.

[0054] Referring to Figures 1 to 6 In some embodiments, the diameter of the exhaust section 221a decreases from one end of the exhaust section 221a away from the sealing section 221b to the other end of the exhaust section 221a close to the sealing section 221b, so that the exhaust section 221a has a certain guiding effect, thereby enabling the sealing part 211 to be smoothly inserted into the sealing section 221b. In addition, after the movable part 230 moves to the second working position to release the restriction, the sealing part 211 can gradually move from the exhaust section 221a to the sealing section 221b until it is inserted into the sealing section 221b to completely seal the through hole 221, which can prevent the sealing part 211 from sealing the through hole 221 too quickly, thereby avoiding the problem of liquid leakage caused by the air inside the through hole 221 being unable to be discharged in time and the atomized liquid in the liquid storage cavity 110 being squeezed into the atomizing core.

[0055] Referring to Figures 1 to 7 In some embodiments, the movable part 230 is provided with a second avoiding through hole 2312 for the sealing part 211 to pass through, and the sealing part 211 can pass through the second avoiding through hole 2312 and seal the through hole 221 when the movable part 230 is located at the second working position. During assembly, the second avoiding through hole 2312 can play a positioning role.

[0056] Referring to Figure 6 and Figure 7 In some embodiments, the second avoiding through hole 2312 is in a strip shape to enable the sealing part 211 to pass through the second avoiding through hole 2312 when the movable part 230 is located at the first working position. During assembly, the sealing part 211 is always arranged in the second avoiding through hole 2312, and the second avoiding through hole 2312 is in a strip shape to prevent the sealing part 211 from interfering with the movement of the movable part 230 relative to the sealing part 220.

[0057] It should be noted that in some other embodiments, the sealing portion 211 can abut against the movable piece 230 when the movable piece 230 is located at the first working position, at which time the sealing portion 211 is misaligned with the second avoiding through hole 2312 to limit the movement of the sealing piece 220 along the longitudinal direction relative to the suction nozzle 210, based on which the first limiting portion 213 and the first avoiding through hole 2311 described above can or can not be provided, which is not limited herein.

[0058] With reference to Figures 1 to 7 In some embodiments, the driving structure includes a pushing portion 130 provided on the housing 100 and protruding out of the opening 120 along the longitudinal direction, and the movable piece 230 includes a main body portion 231 and a force receiving portion 232 provided at one end of the main body portion 231 and extending outwardly and upwardly obliquely, the pushing portion 130 being configured to act on the force receiving portion 232 to drive the movable piece 230 to move from the first working position to the second working position when the suction nozzle assembly is assembled at the opening 120. During the process of blocking the opening 120 by the sealing piece 220, the pushing portion 130 acts on the force receiving portion 232 to gradually move the movable piece 230 from the first working position to the second working position, and after the opening 120 is blocked by the sealing piece 220, the movable piece 230 moves to the second working position to be released from the limitation, so that the suction nozzle 210 can move relative to the sealing piece 220 along the longitudinal direction, and thus the sealing portion 211 provided on the suction nozzle 210 can block the through hole 221.

[0059] With reference to Figures 1 to 7 In some embodiments, the sealing piece 220 is provided with a third avoiding through hole 223 for the pushing portion 130 to pass through, the pushing portion 130 being configured to pass through the third avoiding through hole 223 and act on the force receiving portion 232 to drive the movable piece 230 to move from the first working position to the second working position when the suction nozzle assembly is assembled at the opening 120. On the one hand, the third avoiding through hole 223 can play a positioning role when the sealing piece 220 is assembled, and on the other hand, the hole wall of the third avoiding through hole 223 can play a supporting and protecting role during the process of the pushing portion 130 acting on the force receiving portion 232, which is beneficial to prevent the pushing portion 130 from being broken due to the reaction force.

[0060] With reference to Figure 6 and Figure 7 In some embodiments, the first avoiding through hole 2311 and the second avoiding through hole 2312 are both provided on the main body portion 231.

[0061] It should be noted that in other embodiments, the second avoiding through hole 2312 can also not be provided, which is not limited here. Specifically, the movable part 230 will not block the through hole 221 whether it is located in the first working position or the second working position, that is, the movable part 230 moving to the second working position will not interfere with the sealing part 211 plugging the through hole 221.

[0062] It should be noted that in other embodiments, the movable part 230 can also be manually driven to move by a manual button provided on the outer wall of the shell 100 and connected with the movable part 230, which is not limited here.

[0063] Referring to Figure 7 In some embodiments, the sealing part 220 is provided with an assembly groove 224, and the main body part 231 is arranged in the assembly groove 224, and the main body part 231 can move in the assembly groove 224 from the first working position to the second working position. The assembly groove 224 can limit the activity area of the movable part 230, which is beneficial to improve the stability and reliability of the movable part 230 during work.

[0064] It should be noted that in some embodiments, a positioning structure is arranged between the sealing part 220 and the main body part 231, and the positioning structure is used to position at least one of the first working position and the second working position.

[0069] The liquid injection method of the electronic atomization device according to the embodiments of the present application is applied to the electronic atomization device of the above-mentioned embodiments and includes the following steps.

[0070] A predetermined amount of atomization liquid is injected into the liquid storage cavity 110 through the opening 120;

[0071] The sealing member 220 is blocked at the opening 120, the movable member 230 is driven by the driving structure to move from the first working position to the second working position, and finally the sealing portion 211 blocks the through hole 221 to assemble the mouthpiece assembly at the opening 120.

[0072] It should be noted that in some embodiments, the position of the movable member 230 can be ensured at the first working position before the sealing member 220 is blocked at the opening 120.

[0073] The electronic atomization device according to another embodiment of the present application includes a housing 100, a mouthpiece assembly and a driving structure.

[0074] Specifically, the shell 100 has a liquid storage cavity 110, the liquid storage cavity 110 has an opening 120 at one end of the shell 100 and is used for liquid injection, the suction nozzle assembly includes a suction nozzle 210, a sealing member 220 and a movable member 230 assembled in one body, the sealing member 220 is used for plugging the opening 120 and has a through hole 221 for exhaust, the movable member 230 is movably arranged between the suction nozzle 210 and the sealing member 220, the movable member 230 has a third working position for avoiding the through hole 221 and a fourth working position for plugging the through hole 221, and the driving structure is used for driving the movable member 230 to move from the third working position to the fourth working position.

During the process of applying force to the suction nozzle assembly to make the sealing member 220 plug the opening 120, the movable member 230 does not move to the fourth working position, so that the exhaust can be performed through the through hole 221, thereby facilitating the reduction of the atomized liquid squeezed into the atomizing core during assembly. During the process of plugging the opening 120 by the sealing member 220, or after the opening 120 is plugged by the sealing member 220, the movable member 230 is driven by the driving structure to move from the third working position to the fourth working position to plug the through hole 221. During the above assembly process, the through hole 221 is only used for exhaust, that is, the liquid injection needle is not required to cooperate with the through hole 221 for liquid injection. Compared with the prior art, it is not required to consider that the gap between the liquid injection needle and the inner wall of the through hole 221 is blocked by the atomized liquid during liquid injection. In addition, the through hole 221 is plugged by the movable member 230, compared with the prior art, it is not required to consider that the sealing column is inserted into the through hole 221 to cause the atomized liquid in the liquid storage cavity 110 to be squeezed into the atomizing core, thereby reducing the risk of liquid leakage.

[0076] In addition, the electronic atomization device of another embodiment can use the driving structure and the positioning structure of the electronic atomization device of the above embodiment.

[0077] The liquid injection method of the electronic atomization device according to another embodiment of the present application is applied to the electronic atomization device of another embodiment described above, and includes the following steps:
