Description

Technical Field

[0002] In a cartridge-changeable electronic atomization device, the electronic atomization device includes a main body and an atomization structure. The main body includes a shell and a power supply component fixedly installed on the shell. When the atomization structure is installed on the shell, the power supply component establishes an electrical connection with the atomization structure and supplies power to the atomization structure.

[0003] Atomizing liquid is stored in the atomizing structure, and the atomizing structure uses the electric energy provided by the power supply component to atomize the atomizing liquid. When the atomizing liquid in the atomizing structure is consumed, the atomizing structure is disassembled from the main body, and a new atomizing structure is installed, and the electronic atomizing device can continue to be used.

[0004] The integrated atomization structure has an atomization component immersed in the atomization liquid. Under conditions of long-term storage and transportation, the atomization structure will not only have the problem of leakage, but also cause the atomization liquid to deteriorate. In the related art, based on the above-mentioned problems, a separate atomization structure has been developed, in which the atomization component and the atomization liquid are independently arranged for storage and transportation, etc., which can well avoid the problems of leakage and deterioration of the atomization liquid. However, when using the atomization structure, the user needs to assemble the atomization seat with the atomization component and the liquid storage tank with the atomization liquid together so that the atomization liquid flows to the atomization component before it can be used normally. The assembly process of the atomization seat and the liquid storage tank includes positioning, alignment, installation and other steps, which is relatively cumbersome and requires certain installation technology, which makes it impossible for users to complete the assembly quickly, resulting in the inability of users to quickly use the atomization structure, which seriously affects the user's experience.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0036] The present application proposes an atomization structure 100, which can be applied to an electronic atomization device. The electronic atomization device includes a body and an atomization structure 100. The body is provided with a power supply component. When the atomization structure 100 is installed on the body, the power supply component establishes an electrical connection with the atomization structure 100 and supplies power to the atomization structure 100, so that the atomization structure 100 performs atomization work under the drive of the electric energy. Figures 1 to 5 In the embodiment of the present application, the atomization structure 100 includes a housing assembly 10 and an atomization seat 20 .

[0037] The housing assembly 10 is provided with a liquid storage chamber 10a, a mouthpiece channel 112 and a mounting hole 121 communicating with the liquid storage chamber 10a. The atomizer seat 20 includes an atomizer assembly 21 and a mounting portion 231 having an airflow channel 2311. The mounting portion 231 is also provided with a liquid inlet hole 2312 communicating with the airflow channel 2311. The mounting portion 231 extends into the liquid storage chamber 10a through the mounting hole 121 and is plugged and matched with the mouthpiece channel 112, so that the air outlet end of the airflow channel 2311 is communicated with the mouthpiece channel 112. A first sealing ring 22 is provided at the junction between the mounting portion 231 and the mouthpiece channel 112, and the mounting portion 231 is abutted and sealed against the hole wall of the mounting hole 121. The atomizer assembly 21 is installed in the airflow channel 2311.

[0038] The atomizer seat 20 is movably connected to the shell assembly 10, so that the atomizer seat 20 has an activated state and an inactivated state. When the atomizer seat 20 is in the activated state, the liquid inlet hole 2312 is located in the liquid storage cavity 10a. When the atomizer seat 20 is in the inactivated state, the liquid inlet hole 2312 is located outside the liquid storage cavity 10a.

[0039] The liquid storage chamber 10a is used to store atomized liquid. Specifically, when the electronic atomization device used in the atomization structure 100 is an electronic cigarette, the atomized liquid stored in the liquid storage chamber 10a is smoke oil. It should be emphasized that the mounting hole 121 connected to the liquid storage chamber 10a is used for the mounting portion 231 to extend into the liquid storage chamber 10a. Regardless of whether the atomizer seat 20 is in an activated state or an inactivated state, the mounting portion 231 is abutted and sealed against the hole wall of the mounting hole 121 to prevent the atomized liquid in the liquid storage chamber 10a from leaking out of the mounting hole 121 and contaminating other parts of the atomization structure 100. It can be understood that the abutment and sealing of the mounting portion 231 against the hole wall of the mounting hole 121 means that the mounting portion 231 abuts against the hole wall of the mounting hole 121, and the liquid storage chamber 10a is sealed by abutting against the hole wall of the mounting hole 121.

[0040] The atomizer assembly 21 can be installed in the air flow channel 2311 in a variety of ways, such as: snap-on, plug-in, etc. Among them, the atomizer assembly 21 has a built-in atomizer chamber, and the atomizer assembly 21 uses electrical energy to atomize the atomized liquid in the atomizer chamber to form an aerosol. Since the atomizer assembly 21 is installed in the air flow channel 2311, the aerosol can flow along the air flow channel 2311 under the drive of an external force. It can be understood that the air inlet and air outlet of the air flow channel 2311 are both connected to the outside world, and the external gas enters the air flow channel 2311 from the air inlet, and is discharged to the air outlet under the drive of an external force. When the gas flows through the atomizer assembly 21, the gas will take away the aerosol.

[0041] It can be understood that the atomizer seat 20 is movable relative to the housing assembly 10, and the mounting portion 231 further extends into the liquid storage chamber 10a, so that the atomizer seat 20 is in an activated state. Since the mounting portion 231 is provided with a liquid inlet hole 2312, after the mounting portion 231 extends into a preset length, the liquid inlet hole 2312 will enter the liquid storage chamber 10a along with the mounting portion 231. At this time, the liquid storage chamber 10a can be connected to the air flow channel 2311 through the liquid inlet hole 2312, and the atomized liquid stored in the liquid storage chamber 10a can flow into the air flow channel 2311 through the liquid inlet hole 2312, and the atomizer assembly installed in the air flow channel 2311 21 can use the atomized liquid to generate aerosol; the atomizer seat 20 moves relative to the shell assembly 10, and the mounting portion 231 partially withdraws from the liquid storage chamber 10a, so that the atomizer seat 20 is in an inactive state. After the mounting portion 231 withdraws a preset length, the liquid inlet hole 2312 on the mounting portion 231 withdraws from the liquid storage chamber 10a as the mounting portion 231 partially withdraws from the liquid storage chamber 10a. At this time, the liquid inlet hole 2312 is not in the liquid storage chamber 10a, so the liquid storage chamber 10a cannot be connected to the air flow channel 2311 through the liquid inlet hole 2312, and the atomized liquid stored in the liquid storage chamber 10a cannot flow into the air flow channel 2311. It should be emphasized that usually when the atomizer structure 100 is produced on the production line, the atomizer seat 20 is in an inactive state. When the user uses the atomizer structure 100, the user switches the atomizer seat 20 to an active state.

[0042] According to the atomization structure 100 of the embodiment of the present application, when it is applied to an electronic atomization device, the body of the electronic atomization device provides it with electrical energy and provides the energy required for its normal operation. The atomization component 21 of the atomization structure 100 uses electrical energy to work, and atomizes the atomized liquid into an aerosol in the atomization chamber. The user applies a suction force to the air outlet end of the air flow channel 2311 through the mouth, thereby driving the flow of gas. As the gas flows, the aerosol in the atomization chamber is inhaled into the mouth of the user through the air flow channel 2311. In this process, external gas usually enters the atomization chamber from the air inlet end of the air flow channel 2311, and then flows through the air flow channel 2311 to drive the aerosol into the user's mouth.

[0043] Usually, the extension direction of the mouthpiece channel 112 coincides with the extension direction of the airflow channel 2311 to reduce the resistance of the gas flowing from the airflow channel 2311 to the mouthpiece channel 112. Of course, in other examples, the extension direction of the mouthpiece channel 112 forms a certain angle with the extension direction of the airflow channel 2311.

[0044] It should be emphasized that, whether the atomizer seat 20 is in an activated state or an inactivated state, the mounting portion 231 is plugged into and matched with the mouthpiece passage 112 , and the mounting portion 231 will not be separated from the mouthpiece passage 112 as it partially withdraws from the liquid storage cavity 10a .

[0045] Such a configuration is intended to optimize the specific structure of the atomizing structure 100, so that the gas flowing through the airflow channel 2311 can smoothly flow out along the mouthpiece channel 112. At the same time, since the airflow channel 2311 is connected to the outside through the mouthpiece channel 112, it is avoided that the mounting portion 231 is protruded from the surface of the housing assembly 10, which reduces the foreign body sensation of the user when inhaling the airflow channel 2311, and improves the aesthetics of the atomizing structure 100.

[0046] It can be understood that the mounting portion 231 is plugged into the mouthpiece channel 112 so that the air outlet end of the airflow channel 2311 is connected to the mouthpiece channel 112, and the mouthpiece channel 112 is not directly connected to the liquid storage chamber 10a. Only when the atomizer seat 20 is in an activated state, the liquid storage chamber 10a will be connected to the mouthpiece channel 112 through the liquid inlet hole 2312 and the airflow channel 2311.

[0047] In some examples, the atomizing structure 100 further includes a sealing head, which is plugged into and matched with an end of the mouthpiece channel 112 away from the mounting portion 231 to prevent the atomizing structure 100 from being invaded by foreign objects when not in use.

[0048] The first sealing ring 22 is provided to improve the sealing performance of the liquid storage chamber 10 a and prevent the atomized liquid from leaking out from the gap between the mounting portion 231 and the mouthpiece channel 112 .

[0049] Preferably, the material of the first sealing ring 22 can be rubber, such as natural rubber, nitrile rubber, silicone rubber, fluororubber, etc. The material of the first sealing ring 22 can also be plastic, such as polytetrafluoroethylene, polyurethane, polyoxymethylene, etc.

[0050] In some examples, in order to further improve the sealing performance of the first sealing ring 22, an annular convex ring is convexly provided on the circumferential side of the first sealing ring 22, and the number of the convex rings can be one, two, three, etc. When the number of the convex rings is two or more, the convex rings are spaced apart along the axial direction of the first sealing ring 22.

[0051] In this example, the first sealing ring 22 is arranged on the circumferential side of the mounting portion 231. The first sealing ring 22 moves with the movement of the mounting portion 231. In order to improve the stability of the first sealing ring 22 being sleeved on the mounting portion 231, the circumferential side of the mounting portion 231 is convexly provided with a first limiting protrusion 2313 for limiting the movement of the first sealing ring 22 relative to the mounting portion 231. Preferably, the first limiting protrusion 2313 can be a ring-shaped structure.

[0052] In some other examples, the first sealing ring 22 is fixedly mounted on the inner side of the cigarette holder channel 112 , and when the mounting portion 231 moves relatively, it also moves relative to the first sealing ring 22 .

[0053] The atomization structure 100 provided in the embodiment of the present application is arranged with the above-mentioned structure. When the atomization structure 100 is stored, transported, etc., the atomization seat 20 is maintained or switched to an inactive state, so that the atomized liquid stored in the liquid storage chamber 10a and the atomization component 21 are isolated from each other. In this way, the problem of deterioration of the atomized liquid can be well avoided. When the atomization structure 100 is used, the atomization seat 20 is pushed upward relative to the shell component 10 to switch the atomization seat 20 to an active state, so that the liquid storage chamber 10a is connected with the air flow channel 2311 through the liquid inlet hole 2312, and the atomized liquid stored in the liquid storage chamber 10a can flow into the air flow channel 2311 through the liquid inlet hole 2312, so that the atomization component 21 can use the atomized liquid to perform atomization. It can be seen that compared with the prior art, the technical solution of the present application does not require complicated assembly procedures for the atomizer seat 20 and the liquid storage tank when using the electronic atomization device. It is only necessary to push the atomizer seat 20 upward relative to the shell assembly 10 to switch the atomizer seat 20 to an activated state. The atomization structure 100 can then be used normally, allowing the user to quickly use the atomization structure 100, thereby improving the user experience.

[0054] In some examples, such as Figures 2 to 4 As shown, the housing assembly 10 includes a housing 11 and a sealing member 12. The housing 11 is provided with a liquid storage tank 111. The sealing member 12 is in contact with and sealed against the peripheral wall of the liquid storage tank 111 to enclose and form a liquid storage cavity 10a. The sealing member 12 is also provided with a mounting hole 121. The material of the sealing member 12 can be the same as the material of the first sealing ring 22 mentioned above.

[0055] Such a configuration is intended to optimize the specific structure of the housing assembly 10, so as to facilitate the production and manufacturing of the housing assembly 10, and to improve the assembly efficiency of the housing assembly 10. At the same time, through the above-mentioned structural configuration, the housing 11 can be cup-shaped, so that the housing 11 can be manufactured by an integral injection molding process, thereby improving the production efficiency of the housing assembly 10 and reducing the production cost.

[0056] In addition, the sealing member 12 is in contact and sealed with the peripheral wall of the liquid storage tank 111 to enclose and form the liquid storage chamber 10 a , which can improve the sealing performance of the liquid storage chamber 10 a .

[0057] Considering that the sealing member 12 needs to be stably abutted and sealed against the peripheral wall of the liquid storage tank 111, the sealing performance of the liquid storage chamber 10a can be ensured. In some examples, the peripheral wall of the liquid storage tank 111 is provided with a second limiting protrusion 1113, and the sealing member 12 abuts and cooperates with the second limiting protrusion 1113 to limit the movement of the sealing member 12 relative to the liquid storage tank 111 through the second limiting protrusion 1113, thereby improving the stability of the sealing member 12, wherein the sealing member 12 may also be embedded with a sealing plate 13 to cooperate with the second limiting protrusion 1113, further improving the stability of the sealing member 12, and similarly, the second limiting protrusion 1113 may also be an annular structure.

[0058] In some examples, such as Figures 2 to 5 As shown, the atomizer seat 20 also includes a base 23, which is slidably installed on the liquid storage tank 111 along the depth direction of the liquid storage tank 111 to achieve a movable connection between the atomizer seat 20 and the housing 11, and a mounting portion 231 is installed on one side of the base 23 facing the sealing member 12.

[0059] There are many ways to set the base 23 so that it can be slidably installed in the liquid storage tank 111 along the depth direction of the liquid storage tank 111. In one way, the base 23 can directly slidably abut against the wall of the liquid storage tank 111 so as to be slidably installed in the liquid storage tank 111. In another way, the wall of the liquid storage tank 111 is rollingly provided with balls, and the base 23 is in rolling contact with the balls so as to be slidably installed in the liquid storage tank 111. There are other ways, which are not illustrated one by one here.

[0060] With such a configuration, the atomizer seat 20 can be switched from an inactive state to an active state only by pushing the base 23 toward the liquid storage tank 111 along the depth direction of the liquid storage tank 111, or the atomizer seat 20 can be switched from an inactive state to an active state only by pressing the shell 11 toward the base 23 along the depth direction of the liquid storage tank 111. In this way, the atomizer structure 100 is simple and convenient to use, aiming to further improve the user experience.

[0061] In some examples, such as Figure 4 and Figure 5 As shown, the wall of the liquid storage tank 111 is concavely provided with a slide groove 1111, and the slide groove 1111 is extended along the depth direction of the liquid storage tank 111, and the base 23 is convexly provided with a slider 232 that slidably cooperates with the slide groove 1111. The number of the sliders 232 and the slide grooves 1111 can be multiple, and each slider 232 is correspondingly arranged with a slide groove 1111. When the number of the sliders 232 is two or more, the sliders 232 are arranged at intervals along the circumference of the base 23.

[0062] Such a configuration is intended to improve the sliding stability of the base 23 relative to the housing assembly 10 through the sliding cooperation between the slider 232 and the slide groove 1111.

[0063] In some examples, such as Figure 4 and Figure 5As shown, two positioning holes 1112 are formed on the groove wall of the slide groove 1111, and the two positioning holes 1112 are spaced apart along the depth direction of the liquid storage tank 111. The slider 232 is extended along the depth direction of the liquid storage tank 111, and the slider 232 is provided with a positioning protrusion 2321. When the atomizer seat 20 is in an activated state, the positioning protrusion 2321 is snap-fitted with one positioning hole 1112, and when the atomizer seat 20 is in an inactivated state, the positioning protrusion 2321 is snap-fitted with the other positioning hole 1112.

[0064] The shape of the positioning protrusion 2321 and the positioning hole 1112 are usually mutually adapted, that is, when the positioning protrusion 2321 is cylindrical, the positioning hole 1112 is a corresponding circular hole. The periphery of the positioning protrusion 2321 can be chamfered to facilitate the positioning protrusion 2321 to engage with the positioning hole 1112 or to disengage from the positioning hole 1112.

[0065] Such a configuration can ensure that the atomizing structure 100 will not loosen easily and remain stable when subjected to slight external force, thereby avoiding misoperation of the atomizing structure 100 and switching the atomizing seat 20 to an activated state or an inactivated state. At the same time, the engagement between the slider 232 and the positioning hole 1112 can serve as a hand feel prompt for the switching state.

[0066] In some examples, such as Figure 4 and Figure 5 As shown, a positioning flange 233 is convexly disposed on the circumference of the base 23 , and the positioning flange 233 is located on a side of the base 23 away from the sealing member 12 . When the atomizer seat 20 is in an activated state, the positioning flange 233 abuts against the notch of the liquid storage tank 111 .

[0067] Such a configuration is intended to limit the base 23 from excessively extending into the liquid storage tank 111 by abutting the positioning flange 233 with the notch of the liquid storage tank 111, so as to avoid collision between the base 23 and parts such as the seal 12, resulting in damage to the atomization structure 100.

[0068] In some examples, the notch of the liquid storage tank 111 is also provided with a protruding positioning rib, and the positioning flange 233 is provided with a recessed groove for accommodating the positioning rib.

[0069] Considering that after the atomizer seat 20 is switched to the activated state, the atomized liquid stored in the liquid storage chamber 10a needs to use its own gravity to flow into the air flow channel 2311 through the liquid inlet hole 2312 for the atomizer assembly 21 to work. During this process, the flow of the atomized liquid requires a certain amount of time, and the user needs to wait.

[0070] In some examples, such as Figures 2 to 5As shown, the seal 12 is also provided with a boost hole 122, and the boost hole 122 is arranged to penetrate along the depth direction of the liquid storage tank 111. The atomizer seat 20 also includes a boost structure 24, and the boost structure 24 is connected to the side of the base 23 facing the seal 12, and the boost structure 24 is at least partially accommodated in the boost hole 122 and abuts against the hole wall of the boost hole 122 for sealing. When the atomizer seat 20 is in an activated state, the boost structure 24 enters the liquid storage chamber 10a through the boost hole 122.

[0071] Such arrangement is intended to allow the boosting structure 24 to enter the liquid storage chamber 10a through the boosting hole 122, quickly reduce the volume of the liquid storage chamber 10a, and increase the pressure in the liquid storage chamber 10a. Under the action of this pressure, the atomized liquid stored in the liquid storage chamber 10a can quickly flow into the air flow channel 2311 through the liquid inlet hole 2312 to be used by the atomization component 21. This greatly shortens the user's waiting time and further improves the user's experience.

[0072] In some examples, such as Figures 2 to 5 As shown, a second sealing ring is convexly provided on the hole wall of the boost hole 122, and the boost structure 24 includes a boost column, and the peripheral wall of the boost column is in sliding contact with the second sealing ring.

[0073] The shape of the boost column is adapted to the shape of the boost hole 122, that is, when the boost column is a cylinder, the boost hole 122 is a round hole. The number of the boost column and the boost hole 122 can be multiple, and each boost column is corresponding to a boost hole 122. When the number of the boost columns is two or more, the boost columns are spaced apart.

[0074] Such arrangement aims to improve the sealing performance of the liquid storage tank 111 and prevent the atomized liquid from seeping out along the hole wall of the boosting hole 122 by slidingly abutting the peripheral wall of the boosting column with the second sealing ring.

[0075] In some examples, such as Figures 1 to 4 As shown, the housing assembly 10 is further provided with a liquid injection port 113, which is in communication with the liquid storage chamber 10a, and the atomizing structure 100 further includes a sealing plug 30, which is detachably mounted on the liquid injection port 113 to seal the liquid injection port 113. With such a configuration, when the atomized liquid in the liquid storage chamber 10a is consumed, the atomized liquid can be added to the liquid storage chamber 10a again through the liquid injection port 113, so that the atomizing structure 100 can be reused.

[0076] Similarly, the material of the sealing plug 30 can be the same as the material of the first sealing ring 22 . In combination with the above description of the housing assembly 10 , in this example, the liquid injection port 113 is opened in the housing 11 .

[0077] The present application also proposes an electronic atomization device, which includes a body and an atomization structure 100. The specific structure of the atomization structure 100 refers to the above embodiment. Since the electronic atomization device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the body is provided with a mounting portion 231 and a power supply assembly, and the atomization structure 100 can be detachably mounted on the mounting portion 231. When the atomization structure 100 is mounted on the mounting portion 231, the power supply assembly is electrically connected to the atomization assembly 21.

[0078] In some examples, the atomization structure 100 further includes a receiving electrode 40 , which is mounted on the atomization seat 20 . The receiving electrode 40 is also electrically connected to the atomization assembly 21 via a wire. Specifically, referring to the specific structure of the atomization seat 20 , the receiving electrode 40 is mounted on the base 23 .

[0079] Among them, the receiving electrode 40 is at least partially exposed on the outer surface of the base 23, the power supply system includes an electrode needle and a battery, the electrode needle and the battery are electrically connected through a wire, and when the atomization structure 100 is installed on the mounting portion 231, the receiving electrode 40 and the electrode needle contact each other, so that the atomization component 21 establishes an electrical connection with the battery through the contact between the receiving electrode 40 and the electrode needle.

[0080] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
