DETAILED DESCRIPTION

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] Please refer to Figures 1 to 4 , Figure 1 The Z direction is the up-down direction. The embodiment of the present application provides an atomizing device, which includes:

[0041] A housing, wherein a liquid storage cavity 50 is provided in the housing;

[0042] The atomizer core assembly 400 is located in the housing. The side wall of the atomizer core assembly 400 is provided with a first injection hole 411, and the first injection hole 411 is connected to the inside of the atomizer core assembly 400;

[0043] The driving member is in contact with the bottom of the atomizer core assembly 400 and is used to drive the atomizer core assembly 400 to move relative to the liquid storage chamber 50 so that the first injection hole 411 is connected to or blocked from the liquid storage chamber 50 .

[0044] Specifically, the atomizer core assembly 400 includes an outer cover 410 and an atomizer core 420. The atomizer core 420 is located in the outer cover 410. The first injection hole 411 is provided in the outer cover 410. The liquid storage chamber 50 is used to store the atomized liquid. Figure 2 The atomizer core assembly 400 is located near the bottom of the housing, and the atomized liquid in the liquid storage chamber 50 can only contact the outer wall of the atomizer core assembly 400 (outer cover 410), that is, the atomized liquid cannot enter the atomizer core 420 at this time.

[0045] When the atomizer is in working state, the driving member pushes the atomizer core assembly 400 from bottom to top. Figure 3 , the atomizer core assembly 400 is located near the top of the housing, and the first injection hole 411 moves to the bottom of the liquid storage chamber 50. At this time, the bottom of the liquid storage chamber 50 is connected to the first injection hole 411, and the atomized liquid in the liquid storage chamber 50 will flow from the liquid storage chamber 50 into the inside of the atomizer core assembly 400 along the direction of the hollow arrow in the figure, and contact the atomizer core 420. Therefore, this embodiment can control the movement of the atomizer core assembly 400 relative to the liquid storage chamber 50 through the driving member, so as to achieve control of the atomized liquid, thereby preventing the atomized liquid from contacting the atomizer core 420 for a long time to cause leakage.

[0046] For further information, please refer to Figures 1 to 4 The side wall of the shell is provided with a flow hole 321, and the flow hole 321 is used for allowing external gas to enter the shell. The bottom or side wall of the atomizer core assembly 400 is provided with an air inlet hole 421;

[0047] A flow channel 30 is also provided in the atomizing device. The flow channel 30 passes through the atomizing core assembly 400 , and one end of the flow channel 30 is connected to the air inlet 421 , and the other end is connected to the external environment;

[0048] When the first injection hole 411 is connected to the liquid storage chamber 50 , the flow hole 321 is connected to the air inlet hole 421 .

[0049] Specifically, when the atomizer is working, in addition to allowing the atomized liquid to contact the atomizer core 420, it is also necessary to allow external air to enter the atomizer core 420, so that the user can inhale the aerosol. When the existing atomizer is not working, long-term contact of external air with the atomizer core will cause the performance of the atomizer core to deteriorate, and the service life of the atomizer device will be reduced.

[0050] To solve the above problem, the present embodiment further provides an air inlet hole 421 at the bottom of the atomizing core assembly 400. When the atomizing device is in a non-working state, please refer to Figure 2 The bottom of the atomizer core assembly 400 isolates the flow hole 321 and the air inlet hole 421, that is, the bottom of the atomizer core assembly 400 has an air inlet cavity. When the atomizer core assembly 400 is located at a relatively lower position in the shell, the flow hole 321 cannot be connected to the air inlet cavity.

[0051] When the atomizer core 420 device is in working condition, please refer to Figure 3 , and the driving member pushes it upward, when the first injection hole 411 is connected to the liquid storage chamber 50, as the position of the bottom of the atomizer core assembly 400 moves, the air inlet chamber becomes larger, and after the flow hole 321 can be connected to the air inlet chamber, the external gas can flow along Figure 3 The direction of the solid arrow is inhaled by the user, and during the inhalation process, the aerosol is driven to move through the atomizer core 420. In summary, this embodiment realizes the control of the external gas connection, which can increase the service life of the atomizer core assembly 400.

[0052] For further information, please refer to Figures 1 to 4 The atomizing device further comprises a sealing member 300, at least part of which is located in the housing, and a liquid storage chamber 50 is defined between the outer wall of the sealing member 300 and the inner top wall and inner side wall of the housing;

[0053] A sliding channel 40 is disposed inside the sealing member 300 , and at least a portion of the atomizing core assembly 400 is located in the sliding channel 40 .

[0054] In this embodiment, a sealing member 300 is provided, and the space enclosed and defined between the sealing member 300 and the housing is used as a liquid storage chamber 50, so that the assembly of the liquid storage chamber 50 is modular and easy to assemble, thereby improving the production efficiency of the atomization device; at the same time, the sliding channel 40 in the sealing member 300 guides the atomization core assembly 400, thereby preventing it from being displaced and bumped during movement, thereby effectively improving the service life of the atomization core 420 device.

[0055] It can be understood that, in this embodiment, at least part of the sealing member 300 plays the role of the outer shell of the atomizing device, and the flow hole 321 can be arranged on the sealing member 300 at this time.

[0056] For further information, please refer to Figures 1 to 4 The bottom of the atomizing core assembly 400 is provided with an annular protrusion 412, and the bottom 320 of the sealing member is provided with an annular groove 322 on one side facing the annular protrusion 412, and the annular groove 322 matches the shape and size of the annular protrusion 412;

[0057] When the first injection hole 411 is connected to the liquid storage chamber 50 , the annular protrusion 412 is located in the annular groove 322 .

[0058] When the atomizer core assembly 400 is driven from bottom to top by the driving member, the cooperation between the annular protrusion 412 and the annular groove 322 can guide the atomizer core 420. At the same time, a curved gap structure (not marked in the figure) is formed between the annular protrusion 412 and the annular groove 322, and the curved gap structure can prevent the atomized liquid from directly penetrating under the atomizer core assembly 400 during the movement of the atomizer core assembly 400, thereby preventing liquid leakage.

[0059] For further information, please refer to Figures 1 to 4 The sealing member 300 includes a protruding portion 310 and a sealing member bottom 320 connected to each other, the protruding portion 310 protrudes in a direction away from the sealing member bottom 320, and the sliding channel 40 connects the protruding portion 310 and the sealing member bottom 320;

[0060] The housing includes a liquid storage cover 140 and a liquid storage wall 200, one end of the liquid storage wall 200 is sleeved on the bottom 320 of the sealing member, and the other end is sleeved on the liquid storage cover 140;

[0061] Among them, the liquid storage cover 140, the protrusion 310, the sealing bottom 320, and the liquid storage wall 200 jointly define a liquid storage chamber 50, and the protrusion 310 is provided with a second injection hole 311. When the first injection hole 411 is connected to the liquid storage chamber 50, the second injection hole 311 is connected to the first injection hole 411.

[0062] Specifically, when the liquid storage wall 200 is sleeved on the liquid storage cover 140 and the sealing bottom 320, a liquid storage cavity 50 is formed between the inner wall of the liquid storage wall 200, the lower surface of the liquid storage cover 140, the outer wall of the protrusion 310 and the upper surface of the sealing bottom 320 to accommodate the atomized liquid.

[0063] It is understandable that the second injection hole 311 can be provided at the connection between the protrusion 310 and the bottom 320 of the seal, thereby avoiding the atomized liquid from remaining. The liquid storage wall 200 can be a transparent device such as glass or plastic, thereby facilitating the user to observe the volume of the atomized liquid inside the liquid storage cavity 50 at any time, and then replenish the atomized liquid.

[0064] For further information, please refer to Figures 1 to 5 The liquid storage cover 140 is provided with a liquid exchange hole 141, and the liquid exchange hole 141 connects the liquid storage chamber 50 and the external environment. The atomization device also includes a liquid exchange hole sealing cover 120, which is sleeved on the liquid storage cover 140 and seals the liquid exchange hole 141; and / or,

[0065] The liquid storage wall 200, the liquid storage upper cover 140, and the sealing member bottom 320 are all interference fit; and / or,

[0066] A sealing ring 110 is disposed between the liquid storage wall 200 , the liquid storage upper cover 140 , and the sealing member bottom 320 .

[0067] Specifically, in order to enable the addition of atomized liquid when the atomized liquid capacity in the liquid storage chamber 50 is insufficient, the present embodiment provides a liquid replacement hole 141 on the liquid storage upper cover 140. When the atomized liquid needs to be replenished, the connection between the liquid replacement hole sealing cover 120 and the liquid storage upper cover 140 can be released, thereby allowing the liquid replacement hole 141 to leak out, and then the atomized liquid can be added.

[0068] The liquid storage wall 200 needs to be tightly connected to the liquid storage cover 140 and the sealing bottom 320 to avoid leakage. Therefore, the present application also avoids leakage of atomized liquid through structures such as interference fit and sealing ring 110.

[0069] For further information, please refer to Figures 1 to 5 When the liquid storage cover 140 is provided with a liquid exchange hole 141, the atomizing device is further provided with a liquid exchange hole sealing gasket 130, and the liquid exchange hole sealing gasket 130 is located between the liquid exchange hole 141 and the liquid exchange hole sealing cover 120, and is used to seal the liquid exchange hole 141; and / or,

[0070] The atomizing device further includes a suction nozzle 10 , which is penetrated through the liquid storage upper cover 140 and the liquid exchange hole sealing cover 120 , and is threadedly connected to the liquid storage upper cover 140 .

[0071] Specifically, in order to prevent the liquid in the liquid storage chamber 50 from leaking out of the liquid exchange hole 141 during the use of the atomizing device, the present embodiment is further provided with a liquid exchange hole sealing gasket 130, whereby the liquid exchange hole sealing gasket 130 is pressed onto the liquid exchange hole 141 by means of the liquid exchange seal, thereby blocking the liquid exchange hole 141 to prevent the leakage of the atomized liquid. The threaded connection between the suction nozzle 10 and the liquid storage upper cover 140 enables the suction nozzle 10 to be quickly disassembled, and plays a role in fixing the liquid exchange hole sealing cover 120 to prevent it from loosening.

[0072] For further information, please refer to Figures 1 to 4 The atomizing device further comprises an elastic member 20 , which is located in the sliding channel 40 , and one end of the elastic member 20 abuts against the inner top wall of the sliding channel 40 , and the other end abuts against the atomizing core assembly 400 , so as to drive the atomizing core assembly 400 to reset.

[0073] Specifically, if the atomizer core assembly 400 is driven to reset by a driving member, additional energy of the battery 600 is consumed, resulting in a decrease in the use time of the atomizer device. If the atomizer core assembly 400 is allowed to reset naturally with gravity, it will take a long time, resulting in leakage during the descent. Therefore, this embodiment adds an elastic member 20, and applies an elastic force to the atomizer core assembly 400 through the elastic member 20, thereby accelerating the reset speed of the atomizer core assembly 400 and improving the user experience of the atomizer device. It is understandable that the elastic member 20 can be a structure such as a shrapnel or a spring.

[0074] For further information, please refer to Figures 1 to 4 and Figure 6 The atomizer core 420 also includes a PCBA board 540, and the driving component includes a motor 520, a motor 520 fixing seat and an electrode 530. One end of the motor 520 abuts against the motor 520 fixing seat, and the other end is electrically connected to the PCBA board 540. The electrode 530 is electrically connected to the PCBA board 540 and is penetrated through the motor 520 fixing seat.

[0075] At this time, the PCBA board 540 can control the motor 520 to drive the motor 520 fixing seat, so that the motor 520 fixing seat pushes the atomizer core assembly 400 to move. The motor 520 and the motor 520 fixing seat can be connected by a latch, and the motor 520 and the housing bracket can also be connected by a latch, a buckle, or other connection methods.

[0076] Furthermore, the atomization device also includes a battery 600 and a button 700. The button 700 is snapped onto the bottom of the shell and defines a battery 600 accommodating cavity (not marked in the figure) with the shell. The battery 600 is located in the battery 600 accommodating cavity. The button 700 and the battery 600 are both electrically connected to the PCBA board 540.

[0077] It is understandable that, at this time, in order to facilitate the assembly of the atomizer, the PCBA board 540 can be one or more pieces, so that the PCBA board 540 can be arranged under the motor 520, the battery 600 and other large components, thereby facilitating assembly. In this embodiment, the user can start the motor 520 by pressing the button 700.
