Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an atomization structure and an electronic atomization device. Background Art

[0002] In a cartridge-changing 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] The atomizing structure stores atomizing liquid, 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 removed 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 atomizing liquid. Under conditions of long-term storage and transportation, the atomization structure will not only have the problem of leakage, but also cause the atomized liquid to deteriorate. In the related art, a separate atomization structure has been developed based on the above-mentioned problems. Its atomization component and atomizing liquid are independently set for storage, transportation, etc., which can well avoid the problems of leakage and deterioration of the atomized liquid. However, when using the atomization structure, the user is required to assemble the atomization seat with the atomization component and the liquid storage tank with the atomizing liquid together so that the atomized 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 steps such as positioning, alignment, and installation, which is relatively cumbersome and requires certain installation technology. This makes it impossible for the user to complete the assembly quickly, resulting in the user being unable to quickly use the atomization structure, seriously affecting the user's experience.

[0014] In some embodiments of the present application, the groove wall of the sliding groove is provided with two positioning holes, and the two positioning holes are spaced apart along the depth direction of the liquid storage groove;

[0015] The sliding block extends along the depth direction of the liquid storage groove, and the sliding block is provided with a positioning protrusion;

[0016] When the atomization seat is in the activated state, the positioning protrusion is matched with one of the positioning holes, and when the atomization seat is in the non-activated state, the positioning protrusion is matched with the other positioning hole.

[0017] In some embodiments of the present application, the bottom is provided with a positioning flange on the side thereof, and the positioning flange is located on the side of the bottom away from the sealing member. When the atomizing seat is in the activated state, the positioning flange is in abutting engagement with the slot of the liquid storage groove.

[0018] In some embodiments of the present application, the sealing member is further provided with a pressurizing hole penetrating through the liquid storage groove along the depth direction of the liquid storage groove, and the hole wall of the pressurizing hole is provided with a second sealing ring.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. 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] This 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 power 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 passage 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 passage 2311. The mounting portion 231 also defines a liquid inlet 2312 communicating with the airflow passage 2311. The mounting portion 231 extends into the liquid storage chamber 10a through the mounting hole 121 and engages with the mouthpiece passage 112, allowing the outlet of the airflow passage 2311 to communicate with the mouthpiece passage 112. A first sealing ring 22 is provided at the junction between the mounting portion 231 and the mouthpiece passage 112. The mounting portion 231 abuts and seals against the wall of the mounting hole 121, securing the atomizer assembly 21 within the airflow passage 2311.

[0038] The atomizer seat 20 is movably connected to the housing 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 inside the liquid storage chamber 10a. When the atomizer seat 20 is in the inactivated state, the liquid inlet hole 2312 is located outside the liquid storage chamber 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 tobacco 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 in abutment 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. 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 outlet ends of the air flow channel 2311 are both connected to the outside world. The external gas enters the air flow channel 2311 from the air inlet end and is discharged to the air outlet end under the drive of an external force. When the gas flows through the atomizer assembly 21, the gas will carry away the aerosol.

[0041] It can be understood that the atomizing seat 20 is movable relative to the shell assembly 10, and the mounting portion 231 further extends into the liquid storage cavity 10a, so that the atomizing seat 20 is in an activated state. Since the liquid inlet hole 2312 is arranged on the mounting portion 231, when the mounting portion 231 extends into the liquid storage cavity 10a by a preset length, the liquid inlet hole 2312 enters the liquid storage cavity 10a along with the mounting portion 231. At this time, the liquid storage cavity 10a can be in communication with the airflow channel 2311 through the liquid inlet hole 2312, and the atomizing liquid stored in the liquid storage cavity 10a can flow into the airflow channel 2311 through the liquid inlet hole 2312, and the atomizing assembly 21 arranged in the airflow channel 2311 can use the atomizing liquid to generate aerosol. The atomizing seat 20 is movable relative to the shell assembly 10, and part of the mounting portion 231 exits the liquid storage cavity 10a, so that the atomizing seat 20 is in a non-activated state. After the mounting portion 231 exits the preset length, the liquid inlet hole 2312 on the mounting portion 231 exits the liquid storage cavity 10a along with part of the mounting portion 231 exiting the liquid storage cavity 10a. At this time, the liquid inlet hole 2312 is not in the liquid storage cavity 10a, so the liquid storage cavity 10a cannot be in communication with the airflow channel 2311 through the liquid inlet hole 2312, and the atomizing liquid stored in the liquid storage cavity 10a cannot flow into the airflow channel 2311. It should be emphasized that usually the atomizing structure 100 is produced on the production line, and the atomizing seat 20 is in a non-activated state. When the user uses the atomizing structure 100, the user switches the atomizing seat 20 to an activated state.

[0042] When the atomizing structure 100 according to the embodiments of the present application is applied to an electronic atomizing device, the body of the electronic atomizing device provides electrical energy for the atomizing structure 100, and provides the energy required for the normal work of the atomizing structure 100. The atomizing assembly 21 of the atomizing structure 100 works by using electrical energy to atomize the atomizing liquid in the atomizing cavity into aerosol. The user applies a suction force to the air outlet end of the airflow channel 2311 by using the mouth, thereby driving the flow of gas. Along with the flow of gas, the aerosol in the atomizing cavity is inhaled by the user through the airflow channel 2311 and into the mouth. In this process, the external gas usually enters the atomizing cavity through the air inlet end of the airflow channel 2311, and then flows through the airflow channel 2311 to drive the aerosol to enter the user's mouth.

[0043] Usually, the extension direction of the mouthpiece channel 112 coincides with the extension direction of the airflow channel 2311, so as 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 an angle with the extension direction of the airflow channel 2311.

[0044] It should be emphasized that whether the atomizing seat 20 is in an activated state or a non-activated state, the mounting portion 231 is inserted and matched with the mouthpiece channel 112, and the mounting portion 231 will not be separated from the mouthpiece channel 112 along with part of the mounting portion 231 exiting the liquid storage cavity 10a.

[0045] This arrangement is intended to optimize the specific structure of the atomizing structure 100, allowing the gas flowing through the airflow channel 2311 to flow smoothly out along the mouthpiece channel 112. Furthermore, because the airflow channel 2311 is connected to the outside world through the mouthpiece channel 112, the mounting portion 231 is prevented from protruding from the surface of the housing assembly 10, reducing the user's foreign body sensation when inhaling through the airflow channel 2311 and improving the aesthetics of the atomizing structure 100.

[0046] It can be understood that the mounting portion 231 is plugged into and matched with 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 that is plugged into and fits 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 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 arranged at intervals 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, and 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 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 by the embodiments of the present application is in the inactive state when the atomization structure 100 is stored or transported, so that the atomization liquid stored in the liquid storage cavity 10a is isolated from the atomization assembly 21, thereby effectively preventing the atomization liquid from deteriorating. When the atomization structure 100 is used, the atomization seat 20 is pushed upward relative to the shell assembly 10 to switch the atomization seat 20 to the active state, so that the liquid storage cavity 10a is in communication with the airflow channel 2311 through the liquid inlet hole 2312, and the atomization liquid stored in the liquid storage cavity 10a can flow into the airflow channel 2311 through the liquid inlet hole 2312, so that the atomization assembly 21 can perform atomization work using the atomization liquid. It can be seen that, compared with the prior art, the technical solution of the present application does not need to perform a complex assembly process on the atomization seat 20 and the liquid storage chamber when the electronic atomization device is used, and only needs to push the atomization seat 20 upward relative to the shell assembly 10 to switch the atomization seat 20 to the active state, so that the atomization structure 100 can be normally used, and the user can quickly use the atomization structure 100, thereby improving the user experience.

[0054] In some examples, as shown in Figures 2 to 4 The shell assembly 10 includes a shell 11 and a sealing member 12. The shell 11 is provided with a liquid storage groove 111, and the sealing member 12 is in abutting sealing with the peripheral wall of the liquid storage groove 111 to 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 that of the first sealing ring 22.

[0055] In this way, the specific structure of the shell assembly 10 is optimized to facilitate the production and manufacturing of the shell assembly 10 and improve the assembly efficiency of the shell assembly 10. At the same time, through the above structure, the shell 11 can be cup-shaped, so that the shell 11 can be manufactured by an integral injection molding process, thereby improving the production efficiency of the shell assembly 10 and reducing the production cost.

[0056] In addition, the sealing member 12 is in abutting sealing with the peripheral wall of the liquid storage groove 111 to form the liquid storage cavity 10a, which can improve the sealing performance of the liquid storage cavity 10a.

[0057] In order to ensure the sealing performance of the liquid storage cavity 10a, the sealing member 12 needs to be stably in abutting sealing with the peripheral wall of the liquid storage groove 111. In some examples, the peripheral wall of the liquid storage groove 111 is provided with a second limiting protrusion 1113, and the sealing member 12 is in abutting cooperation with the second limiting protrusion 1113 to limit the movement of the sealing member 12 relative to the liquid storage groove 111 by the second limiting protrusion 1113, thereby improving the stability of the sealing member 12. The sealing member 12 can also be embedded with a sealing plate 13 to cooperate with the second limiting protrusion 1113, thereby further improving the stability of the sealing member 12. Similarly, the second limiting protrusion 1113 can also be an annular structure.

[0058] In some examples, as shown in Figures 2 to 5 The atomizing seat 20 further comprises a base 23 which is slidingly installed in the liquid storage groove 111 along the depth direction of the liquid storage groove 111 to achieve the movable connection between the atomizing seat 20 and the shell assembly 10, and the installation portion 231 is installed on the side of the base 23 which faces the sealing element 12.

[0059] The base 23 is slidingly installed in the liquid storage groove 111 along the depth direction of the liquid storage groove 111 in various forms, in one form, the base 23 is directly slidingly abutted with the groove wall of the liquid storage groove 111 to be slidingly installed in the liquid storage groove 111, in another form, the groove wall of the liquid storage groove 111 is rollingly provided with a ball, and the base 23 is rollingly contacted with the ball to be slidingly installed in the liquid storage groove 111, and other forms are not exemplified one by one here.

[0060] In this way, only by pushing the base 23 to move into the liquid storage groove 111 along the depth direction of the liquid storage groove 111, the atomizing seat 20 can be switched from the inactivated state to the activated state, or only by pressing the shell 11 to move towards the base 23 along the depth direction of the liquid storage groove 111, the atomizing seat 20 can be switched from the inactivated state to the activated state, so that the use method of the atomizing structure 100 is simple and convenient, and the use experience of the user is further improved.

[0061] In some examples, as shown in Figure 4 and Figure 5 The groove wall of the liquid storage groove 111 is concavely provided with a sliding groove 1111 which is extendingly arranged along the depth direction of the liquid storage groove 111, and the base 23 is convexly provided with a sliding block 232 which is slidingly matched with the sliding groove 1111. The number of the sliding block 232 and the sliding groove 1111 can both be multiple, and each sliding block 232 is correspondingly arranged with a sliding groove 1111, when the number of the sliding block 232 is two or more than two, the sliding blocks 232 are spaced apart along the circumferential direction of the base 23.

[0062] In this way, it is aimed at improving the stability of the sliding of the base 23 relative to the shell assembly 10 through the sliding matching of the sliding block 232 and the sliding groove 1111.

[0063] In some examples, as shown in Figure 4 and Figure 5As shown, the groove wall of the chute 1111 is provided with two positioning holes 1112, which are arranged in the depth direction of the liquid storage groove 111. The sliding block 232 is arranged in the depth direction of the liquid storage groove 111 and is provided with a positioning protrusion 2321. When the atomization seat 20 is in the activated state, the positioning protrusion 2321 is in clamping cooperation with the positioning hole 1112. When the atomization seat 20 is in the non-activated state, the positioning protrusion 2321 is in clamping cooperation with the other positioning hole 1112.

[0064] The shape of the positioning protrusion 2321 is generally matched with the shape of the positioning hole 1112, that is, when the positioning protrusion 2321 is in a cylindrical shape, the positioning hole 1112 is in a corresponding circular hole shape. The periphery of the positioning protrusion 2321 can be chamfered to facilitate the clamping cooperation of the positioning protrusion 2321 with the positioning hole 1112 or the disengagement of the positioning protrusion 2321 from the positioning hole 1112.

[0065] In this way, the atomization structure 100 can be kept stable without being easily loosened under slight external force, and the atomization structure 100 can be prevented from being misoperated to switch the atomization seat 20 to the activated state or the non-activated state. At the same time, the clamping cooperation of the sliding block 232 with the positioning hole 1112 can provide a tactile prompt for switching the state.

[0066] In some examples, as shown in Figure 4 and Figure 5 As shown, the periphery of the base 23 is provided with a positioning flange 233, and the positioning flange 233 is located on the side of the base 23 away from the sealing element 12. When the atomization seat 20 is in the activated state, the positioning flange 233 is in abutting cooperation with the notch of the liquid storage groove 111.

[0067] In this way, the positioning flange 233 is in abutting cooperation with the notch of the liquid storage groove 111 to limit the excessive extension of the base 23 into the liquid storage groove 111, so as to prevent the base 23 from colliding with the sealing element 12 and other parts, thereby preventing the atomization structure 100 from being damaged.

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

[0069] It is considered that after the atomization seat 20 is switched to the activated state, the atomization liquid stored in the liquid storage cavity 10a needs to flow into the airflow channel 2311 through the liquid inlet hole 2312 by using the gravity of the atomization liquid itself for the working use of the atomization assembly 21. During this process, the flow of the atomization liquid needs a certain time, and the user needs to wait.

[0070] In some examples, as shown in Figures 2 to 5As shown, the seal 12 is further provided with a boost hole 122, which is arranged to penetrate along the depth direction of the liquid storage tank 111. The atomizer seat 20 also includes a boost structure 24, which 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 a setting 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 atomizing component 21. This greatly shortens the user's waiting time and further improves the user experience.

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

[0073] The shape of the boosting column is adapted to the shape of the boosting hole 122. That is, when the boosting column is cylindrical, the boosting hole 122 is a circular hole. The number of boosting columns and boosting holes 122 can be multiple, and each boosting column is corresponding to a boosting hole 122. When there are two or more boosting columns, the boosting columns are spaced apart.

[0074] This arrangement is intended to improve the sealing performance of the liquid storage tank 111 by sliding the peripheral wall of the boosting column against the second sealing ring, thereby preventing the atomized liquid from seeping out along the hole wall of the boosting hole 122.

[0075] In some examples, such as Figures 1 to 4 As shown, the housing assembly 10 further defines a liquid injection port 113 that communicates with the liquid storage chamber 10a. The atomizing structure 100 further includes a sealing plug 30 that is detachably mounted on the liquid injection port 113 to seal the liquid injection port 113. With this arrangement, when the atomized liquid in the liquid storage chamber 10a is consumed, atomized liquid can be refilled into the liquid storage chamber 10a through the liquid injection port 113, allowing the atomizing structure 100 to be reused.

[0076] Similarly, the material of the sealing plug 30 can be the same as that of the first sealing ring 22 . In conjunction with the above description of the housing assembly 10 , in this example, the liquid injection port 113 is provided 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 has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the body is provided with a mounting portion 231 and a power supply assembly. 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 and 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 assembly 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 merely an optional embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made using the contents of the present application specification and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
