Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to an atomization device. Background Technology

[0002] Existing atomizing devices typically include an atomizing unit and a power supply unit to power the atomizing unit. The atomizing unit internally comprises an e-liquid storage chamber, an atomizing chamber, and an atomizing coil located within the atomizing chamber. The atomizing chamber is connected to the outside, and the e-liquid storage chamber is connected to the atomizing chamber through an inlet. The atomizing coil absorbs the e-liquid from the storage chamber. During use, the power supply unit powers the atomizing coil, causing the coil to convert the absorbed e-liquid into a vapor for the user to inhale.

[0003] However, existing atomizing devices have the atomizer core already connected to the oil reservoir at the factory, which means that the atomizer core is soaked in oil for a long time before the device is used. The oil is easily oxidized, affecting the taste and resulting in a poor user experience. Summary of the Invention

[0004] The main objective of this invention is to provide an atomization device that addresses the problem that e-liquid in existing atomization devices is easily oxidized due to prolonged contact with air before atomization, ultimately affecting the aerosol's flavor.

[0007] Optionally, the end of the abutment member is provided with a limiting groove. In the direction away from the driving part, the movable part includes a sealing section, a connecting section and a limiting section in sequence. The outer peripheral wall of the sealing section movably abuts against the inner peripheral wall of the movable channel to seal one end of the movable channel near the oil storage cavity. When the movable sealing sleeve is in the oil inlet position, the limiting section is at least partially inserted into the limiting groove.

[0008] Optionally, the limiting segment is hemispherical, the outer diameter of the limiting segment gradually increases in the direction away from the connecting segment, and the shape of the limiting groove corresponds to the formation of the limiting segment.

[0009] Optionally, the outer diameter of the connecting section is smaller than the outer diameter of the movable part, so as to form a limiting step at the connection between the two. The power supply device is also provided with a locking arm on the outside of the top abutment. The locking arm has a locking protrusion on the side facing the top abutment. The locking protrusion is located above the limiting groove. There is a movable gap between the locking arm and the inner wall of the movable channel. When the movable sealing sleeve is in the oil inlet position, the locking protrusion is located above the limiting section, and its downward projection falls into the step surface located on the limiting step. When the movable sealing sleeve is in the oil blocking position, the driving part abuts against the upper side of the sealing assembly.

[0010] Optionally, the sidewall of the movable channel is formed with a foolproof recess, the foolproof recess extending to the end of the movable channel away from the oil reservoir, and the locking arm extending into the foolproof recess.

[0011] Optionally, there are two movable channels, which are respectively located on opposite outer sides of the atomizing tube. There are also two abutment members, which are respectively arranged corresponding to the two movable channels.

One of the inner peripheral wall of the sleeve and the outer peripheral wall of the movable sealing sleeve is provided with a limiting protrusion, and the other is provided with a limiting groove. The limiting protrusion is inserted into the limiting groove.

[0012] Optionally, the outer wall of the sleeve is provided with reinforcing ribs, which extend from the top of the sleeve and are connected to the driving block. There are multiple reinforcing ribs, which are arranged at intervals along the circumference of the sleeve.

[0013] Optionally, the sealing assembly includes a mounting base, a base, and a sealing cylinder. The mounting base is installed on the chamber to seal the opening of the chamber. The mounting base has spaced mounting holes and insertion holes. The lower end of the atomizing tube is inserted into the insertion hole. The sealing cylinder is installed in the mounting hole and has through holes extending through its upper and lower ends. The base is installed on the lower side of the mounting base and has through holes extending through its upper and lower sides. The mounting holes, through holes, and through holes form the movable channel.

[0014] Optionally, the sealing cylinder is made of silicone or silicone rubber, and the inner wall of the through hole is provided with a sealing protrusion that abuts against the outer peripheral wall of the movable part; and / or, The mounting hole has a limiting ring protruding from one end near the oil storage cavity.

[0015] The technical solution of this invention, by setting a movable frame to move the movable sealing sleeve, allows the atomizing device and the power supply device to be separated before the atomizing device is used. The movable sealing sleeve is then operated to the oil-blocking position, blocking the oil inlet and storing the e-liquid in a sealed oil storage chamber. This prevents oxidation by air, ensuring the quality of the e-liquid and thus guaranteeing the taste after atomization, improving the user experience. When the atomizing device is needed, the power supply device and the atomizing device are inserted together. A top abutment that can abut the movable part of the power supply device ensures that after insertion, the movable sealing sleeve is moved to the oil inlet position. At this point, the e-liquid in the storage chamber can flow through the oil inlet and be absorbed into the atomizing core, ready for subsequent atomization for the user to inhale.

[0022] The following will mainly describe the specific structure of the atomizing device 10.

[0023] Reference Figures 1 to 7 In this embodiment of the invention, the atomizing device includes: Atomizing device 10 includes a chamber 100, an atomizing tube 200, an atomizing core 300, a sealing assembly, a movable frame 500, and a movable sealing sleeve 600. The lower end of the chamber 100 is open. The sealing assembly is installed at the lower end of the chamber 100 to seal its opening. The atomizing tube 200 is installed between the inner wall of the chamber 100 and the sealing assembly to form an oil storage chamber 101. The sealing assembly has a movable channel 401 extending through its upper and lower ends to connect the oil storage chamber 101 with the outside. The atomizing tube 200 forms an atomizing chamber 210 and a connecting channel 401 between the atomizing chamber 210 and the oil storage chamber 101. The atomizing core 300 is installed in the atomizing chamber 210, and the movable sealing sleeve 600 is disposed in the atomizing tube 200. The movable frame 500 includes a connected driving part 520 and a movable part 510. The movable part 510 is movably inserted into the movable channel 401 and keeps the movable channel 401 sealed. The driving part 520 is installed and cooperates with the movable sealing sleeve 600 so that the movable sealing sleeve 600 has an oil-blocking position that blocks the oil inlet 220 and an oil-inlet position that exposes the oil inlet 220. The oil-inlet position is located above the oil-blocking position. The power supply device 200 is detachably inserted into the atomizing device 10. The power supply device 200 is provided with a top abutment 700 at the position corresponding to the movable channel 401. When the power supply device 200 is inserted into the atomizing device 10, the top abutment 700 extends into the movable channel 401 and abuts against the movable part 510 upwards, so as to place the movable sealing sleeve 600 in the oil inlet position.

[0024] Specifically, in this embodiment, when the atomizing device leaves the factory, the atomizing device 10 and the power supply device 200 are not initially connected together, and the movable sealing sleeve 600 is operated to the oil-blocking position, so that the oil inlet 220 is blocked by the movable sealing sleeve 600. In this way, the oil storage chamber 101 is not connected to the atomizing core 300, and the oil is stored in the sealed oil storage chamber 101, which is not easily oxidized by air, thus ensuring the quality of the e-liquid. When the user needs to vape the atomizing device, the power supply device 200 and the atomizing device 10 are connected together. By reasonably setting the position and size of the abutment 700, during the connection process, the abutment 700 can abut upward against the movable part 510 to push the movable part 510 upward. The movable part 510 drives the movable sealing sleeve 600 to move through the driving part 520, so that after the power supply device 200 and the atomizing device 10 are connected in place, the movable sealing sleeve 600 moves to the oil inlet position and opens the oil inlet 220. At this time, the oil in the oil storage chamber 101 can flow and be adsorbed into the atomizing core 300 through the oil inlet 220. When the user inhales the atomizing device, the power supply device 200 supplies power to the atomizing core 300, so that the atomizing core 300 converts the adsorbed liquid into aerosol for the user to inhale.

[0025] The technical solution of this invention, by setting a movable frame 500 to move the movable sealing sleeve 600, allows the atomizing device 10 and the power supply device 200 to be separated before the atomizing device is used. The movable sealing sleeve 600 is then operated to the oil-blocking position, blocking the oil inlet 220. This allows the e-liquid to be stored in the sealed oil storage chamber 101, preventing oxidation by air and ensuring the quality of the e-liquid. This, in turn, guarantees the taste of the e-liquid after atomization, improving the user experience. When the atomizing device is needed, the power supply device 200 is inserted into the atomizing device 10. A top abutment 700 that can abut against the movable part 510 is provided on the power supply device 200. After the power supply device 200 and the atomizing device 10 are inserted into place, the movable sealing sleeve 600 is moved to the oil inlet position. At this time, the e-liquid in the oil storage chamber 101 can flow through the oil inlet 220 and be absorbed into the atomizing core 300, ready for subsequent atomization into an atomizer for the user to inhale.

[0026] In some embodiments, the driving part 520 is provided with a locking hole 522 extending through its upper and lower sides. A limiting arm 411 protrudes from the upper side of the sealing assembly. One side of the limiting arm 411 protrudes from a limiting protrusion 412. The limiting arm 411 passes through the locking hole 522, and the limiting protrusion 412 is located above the locking hole 522. When the movable sealing sleeve 600 is in the oil inlet position, the lower side of the limiting protrusion 412 abuts against the wall of the locking hole 522. The limiting arm 411 and the limiting protrusion 412 limit the movement of the movable frame 500, preventing the atomizing device from moving upwards under significant vibration or other special circumstances. This ensures that the movable part 510 of the movable frame 500 does not detach from the movable channel 401, thereby ensuring that the movable part 510 maintains a seal on the movable channel 401, ensuring the sealing of the oil storage chamber 101, and preventing oil leakage.

[0027] In some embodiments, the end of the abutment 700 is provided with a limiting groove 710. In the direction away from the driving part 520, the movable part 510 sequentially includes a sealing section 511, a connecting section 512, and a limiting section 513. The outer peripheral wall of the sealing section 511 movably abuts against the inner peripheral wall of the movable channel 401 to seal one end of the movable channel 401 near the oil storage chamber 101. When the movable sealing sleeve 600 is in the oil inlet position, the limiting section 513 is at least partially inserted into the limiting groove 710. In this way, the abutment 700 can limit the movable part 510, ensuring that it will not tilt or deviate during the movement, thereby ensuring the movable frame 500 moves along the preset installation route, and thus ensuring the reliability of the movable frame 500 in use. Furthermore, the limiting segment 513 is hemispherical in shape, and its outer diameter gradually increases in the direction away from the connecting segment 512. The shape of the limiting groove 710 corresponds to the formation of the limiting segment 513. Thus, the surface of the limiting segment 513 is smooth and has a guiding function, allowing it to smoothly enter the limiting groove 710, thereby improving the smoothness of installation between the atomizing device 10 and the power supply device 200.

[0028] In some embodiments, the outer diameter of the connecting section 512 is smaller than the outer diameter of the movable part 510, so as to form a limiting step at the connection between the two. The power supply device 200 is also provided with a locking arm 800 on the outside of the top abutment 700. The locking arm 800 has a locking protrusion 810 protruding on the side facing the top abutment 700. The locking protrusion 810 is located above the limiting groove 710. There is a movable gap between the locking arm 800 and the inner sidewall of the movable channel 401. When the movable sealing sleeve 600 is in the oil inlet position, the locking protrusion 810 is located above the limiting section 513, and its downward orthogonal projection part falls into the step surface located on the limiting step. When the movable sealing sleeve 600 is in the oil blocking position, the driving part 520 abuts against the upper side of the sealing assembly. Specifically, in this embodiment, during the insertion process of the power supply device 200 and the atomizing device 10, the locking arm 800 gradually extends into the movable channel 401. When the locking protrusion 810 reaches the limiting section 513, due to the movable gap between the locking arm 800 and the inner wall of the movable channel 401, the locking arm 800 can deform and expand outward under the action of the squeezing force, so that the locking protrusion 810 can move around the limiting section 513 to the top of the limiting section 513. After the locking protrusion 810 moves around the limiting section 513, the locking arm 800 resets, so that the end of the locking protrusion 810 enters the top of the step surface of the limiting step. When the user needs to remove the atomizing device 10 or the power supply device 200, the power supply device 200 can be pulled downwards. The latch 810, as it moves downwards, abuts against the step surface of the limiting step, thereby driving the limiting section 513 downwards. This ultimately drives the movable sealing sleeve 600 to the oil-blocking position, obstructing the oil inlet 220. At this time, the driving part 520 abuts against the upper side of the sealing assembly, thus limiting the limiting section 513 from further downward movement. Continuing to pull the power supply device 200 downwards causes the latch arm 800 to extend outwards, allowing the latch 810 to move around the limiting section 513 and move below it, after which the power supply device 200 can be detached from the atomizing device 10. That is, in this embodiment, removing the atomizing device 10 or the power supply device 200 simultaneously drives the movable sealing sleeve 600 to the oil-blocking position, achieving the purpose of locking the oil. When the atomizing device is not in use, the e-liquid is stored in a sealed oil storage chamber 101, which is not easily oxidized by air, thus ensuring the quality of the e-liquid and guaranteeing the taste after the e-liquid is atomized into mist, thereby improving the user experience.

[0029] In some embodiments, a foolproof recess 402 is formed on the sidewall of the movable channel 401, extending to the end of the movable channel 401 away from the oil storage chamber 101, and the locking arm 800 extends into the foolproof recess 402. When the user inserts the power supply device 200 into the atomizing device 10, the locking arm 800 is aligned with the foolproof recess 402 for assembly, thus facilitating the user's observation of the installation direction and preventing reverse installation.

[0030] In some embodiments, there are two movable channels 401, which are respectively disposed on opposite outer sides of the atomizing tube 200. There are also two abutment members 700, which are respectively disposed corresponding to the two movable channels 401. The driving part 520 includes a driving block 521 and a sleeve 523 protruding from the upper side of the driving block 521. Two movable parts 510 are protruding from the lower side of the driving block 521. The two movable parts 510 are located on opposite sides of the sleeve 523. The sleeve 523 is hollow. The driving block 521 has through holes that penetrate its upper and lower sides corresponding to the hollow area of ​​the sleeve 523, so that the sleeve 523 can be fitted onto the movable sealing sleeve 600. One of the inner peripheral wall of the sleeve 523 and the outer peripheral wall of the movable sealing sleeve 600 is provided with a limiting protrusion 524, and the other is provided with a limiting groove. The limiting protrusion 524 is inserted into the limiting groove. Thus, the sleeve 523 and the movable sealing sleeve 600 mutually limit each other, allowing the movable frame 500 to stably drive the movable sealing sleeve 600 to move. Furthermore, the two abutting parts 700 drive the movable frame 500 to move, ensuring that the movable frame 500 is subjected to balanced forces, thereby improving the stability and smoothness of the movement of the movable frame 500 in driving the movable sealing sleeve 600, and enhancing the user's operating experience.

[0031] Furthermore, the outer wall of the sleeve 523 is provided with reinforcing ribs 525. These reinforcing ribs 525 extend from the top of the sleeve 523 and connect to the driving block 521. Multiple reinforcing ribs 525 are arranged at intervals along the circumference of the sleeve 523. The inclusion of reinforcing ribs 525 improves the strength of the sleeve 523, making it less prone to deformation and thus enabling stable movement of the movable sealing sleeve 600.

[0032] Regarding the formation of the active channel 401, in some embodiments, the sealing assembly includes a mounting base 410, a base 420, and a sealing cylinder 430. The mounting base 410 is installed on the chamber 100 to seal the opening of the chamber 100. The mounting base 410 has mounting holes 413 and insertion holes 415 spaced apart. The lower end of the atomizing tube 200 is inserted into the insertion hole 415. The sealing cylinder 430 is installed in the mounting hole 413 and has through holes penetrating its upper and lower ends. The base 420 is installed on the lower side of the mounting base 410 and has through holes penetrating its upper and lower sides. The mounting holes 413, through holes, and through holes constitute the active channel 401. The sealing cylinder 430 is made of an elastic material to provide a good sealing effect, such as silicone or rubber. To ensure the sealing of the movable channel 401, a sealing protrusion 431 can be provided on the inner wall of the through hole, which abuts against the outer peripheral wall of the movable part 510. The sealing assembly also includes a sealing ring 440, the outer peripheral wall of which abuts against the inner peripheral wall of the chamber 100, thus ensuring the sealing of the oil storage cavity 101 and preventing oil leakage.

[0033] To improve the stability of the mounting cylinder, in some embodiments, a limiting ring 414 extending circumferentially along the wall of the mounting hole 413 near the oil storage chamber 101 is provided. A support arm 421 protrudes upward from the wall of the through hole, and the mounting cylinder is clamped between the limiting ring 414 and the support arm 421. This ensures the mounting cylinder is securely installed in the preset position, guarantees the stability of the movable channel 401, and ensures that the movable part 510 maintains a sealed movable channel 401 during movement, preventing oil leakage.
