Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomizer, a liquid storage device, and an atomization apparatus thereof. Background Technology

[0002] The atomizer is a crucial structure in an atomization device, used to store the substrate to be atomized and to heat and atomize the substrate into an inhalable aerosol. The structure within the atomizer that stores the substrate is the reservoir. As the substrate in the reservoir is consumed, it can be replenished to extend the atomizer's lifespan. A common method of replenishment is to connect an external reservoir to the atomizer's built-in reservoir.

[0003] However, during non-use processes such as transportation, external liquid storage devices may leak due to improper sealing of the liquid outlet. The common method to prevent leakage is to use a spring structure to seal the liquid outlet, which is complex and costly. Utility Model Content

[0004] The embodiments of this application provide an atomizer, a liquid storage component, and an atomizing device thereof, which can seal the external liquid storage component when not in use without affecting the normal use of the external liquid storage component, and can replenish and supply liquid to the liquid storage component of the atomizer, thereby extending the service life of the atomizer.

[0005] This application provides an atomizer, comprising: a first liquid reservoir having a liquid inlet channel and a connector; one end of the liquid inlet channel having a liquid inlet opening communicating with the outside of the first liquid reservoir; one end of the connector being disposed within the liquid inlet channel; and the other end of the connector extending toward the liquid inlet opening; and a second liquid reservoir having a second liquid storage chamber, a connecting channel, and a seal; one end of the connecting channel having a connecting opening communicating with the outside of the second liquid reservoir; and the seal being slidably disposed within the connecting channel; wherein the connecting channel is communicatively connected to the liquid inlet channel to allow communication between the first liquid reservoir and the second liquid reservoir; the connecting channel having a first relative position and a second relative position; and the connector allowing the seal to switch between the first relative position and the second relative position; when the seal is in the first relative position, it blocks communication between the second liquid storage chamber and the connecting opening; and when the seal is in the second relative position, it connects the second liquid storage chamber and the connecting opening.

[0006] In some embodiments, the connection channel is provided with a first limiting structure and a second limiting structure. The first limiting structure is disposed at one end of the connection channel near the connection opening, and the second limiting structure is disposed at one end of the connection channel away from the connection opening. The sealing member abuts against the first limiting structure within the connection channel to place the sealing member in a first relative position; the sealing member abuts against the second limiting structure within the connection channel to place the sealing member in a second relative position.

[0007] In some embodiments, the seal is provided with a groove on the side near the connection opening, and the connector is provided with a boss structure at one end extending toward the liquid inlet opening; the boss structure and the groove are engaged to allow the seal to move with the movement of the connector.

[0008] In some embodiments, the boss structure has a boss guide portion and a boss tail portion, the boss guide portion being disposed at one end near the seal, and the boss tail portion being disposed at one end away from the seal; wherein, the outer diameter of the boss tail portion is larger than the inner diameter of the slot inlet.

[0009] In some embodiments, the seal is made of an elastic seal, and the resistance between the groove and the boss structure is greater than the resistance between the seal and the connecting channel, so that the seal is held in the first relative position.

[0010] In some embodiments, one of the connector and the seal is a magnetic element, and the other is a magnetic or metallic element, so that the seal moves with the movement of the connector by magnetic attraction.

[0011] In some embodiments, the connecting channel has at least one communicating hole on the side near the second limiting structure, and the connecting channel communicates with the second liquid storage chamber through the communicating hole; wherein, when the sealing member is in the first relative position, the communicating hole is misaligned with the sealing member, or the area of ​​the communicating hole is larger than the area covered by the sealing member covering the communicating hole.

[0012] In some embodiments, one end of the connector extending toward the liquid inlet is provided to extend beyond the liquid inlet, so that the connector extends into the connection channel through the connection opening.

[0013] This application embodiment also provides a liquid storage device, which has a liquid storage cavity, a connecting channel and a sealing member. One end of the connecting channel has a connecting opening that communicates with the outside of the liquid storage device. The sealing member is slidably disposed in the connecting channel. The sealing member has a first relative position and a second relative position in the connecting channel. When the sealing member is in the first relative position, it blocks the liquid storage cavity from communicating with the connecting opening. When the sealing member is in the second relative position, the connecting opening communicates with the liquid storage cavity.

[0014] This application also provides an atomizing device, which includes an atomizer and a battery assembly. The battery assembly is connected to the atomizer, and the atomizer is any one of the atomizers described above.

Its structure is simple and can reduce costs. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] First, the existing leak-proof methods for external liquid reservoirs are introduced. Existing electronic atomizing devices typically use a spring-based leak-proof structure (also called a child lock structure). This structure is difficult to meet food-grade requirements due to the limitations of the spring material. Furthermore, this structure requires a combination of multiple components such as sealing silicone, springs, and supports, resulting in high costs. Existing external liquid reservoirs also include oil bottles, etc. Based on this, the following embodiments are provided to illustrate the leak-proof structure of this application. It should be noted that in this application, "liquid" and "oil" are both atomizing matrices that can be heated and atomized to form an aerogel.

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 One embodiment of this application provides an atomizer 200, comprising:

[0032] The first liquid storage device 10 is provided with a liquid inlet channel 11 and a connector 12. One end of the liquid inlet channel 11 is provided with a liquid inlet opening 111 that connects to the outside of the first liquid storage device 10. One end of the connector 12 is disposed inside the liquid inlet channel 11, and the other end of the connector 12 extends toward the liquid inlet opening 111.

[0033] The second liquid storage component 20 is provided with a second liquid storage chamber 23, a connecting channel 21 and a sealing component 22. One end of the connecting channel 21 is provided with a connecting opening 211 that communicates with the outside of the second liquid storage component 20. The sealing component 22 is slidably disposed in the connecting channel 21.

[0034] The connecting channel 21 can communicate with the liquid inlet channel 11 to connect the first liquid storage component 10 and the second liquid storage component 20. The connecting channel 21 is provided with a first relative position A (refer to the mark A in the attached figure) and a second relative position B (refer to the mark B in the attached figure). The connector 12 can switch the sealing component 22 between the first relative position A and the second relative position B. When the sealing component 22 is in the first relative position A, it blocks the second liquid storage cavity 23 from communicating with the connecting opening 211. When the sealing component 22 is in the second relative position B, it connects the second liquid storage cavity 23 with the connecting opening 211.

[0035] In this embodiment, the first liquid storage component 10 can be a liquid storage component fixedly installed inside the atomizer 200, or it can be an external liquid storage component. In the former case, the first liquid storage component 10 is provided with a first liquid storage chamber 13 and an atomizing core 16. The first liquid storage chamber 13 is connected to one end of the liquid inlet channel 11. The first liquid storage chamber 13 is used to store the substrate to be atomized. The atomizing core 16 is connected to the first liquid storage chamber 13 and is used to heat the atomizing substrate to form an aerosol. In one example, the first liquid storage chamber 13 is provided with a liquid storage cotton 131 for storing the substrate to be atomized. The liquid inlet channel 11 is used to connect the first liquid storage chamber 13 and the outside of the first liquid storage component 10, so that liquid can be replenished to the first liquid storage chamber 13 in the first liquid storage component 10 through the liquid inlet channel 11. The connector 12 is used to cooperate with the seal 22 in the second liquid storage 20. On the one hand, it can control the movement of the seal 22. On the other hand, when the liquid inlet channel 11 of the first liquid storage 10 and the connecting channel 21 of the second liquid storage 20 are aligned and connected, the connector 12 also plays the role of aligning and positioning the liquid inlet opening 111 and the connecting opening 211.

[0036] In this embodiment, the second liquid storage component 20 is an external liquid storage component, such as an oil bottle. The second liquid storage component 20 has a second liquid storage chamber 23 for storing the atomized matrix. A connecting channel 21 connects the second liquid storage chamber 23 and the outside of the second liquid storage component 20, allowing the atomized matrix in the second liquid storage chamber 23 to be transported to the first liquid storage component 10 via the connecting channel 21. A sealing member 22 is slidably disposed within the connecting channel 21, used to seal or open the connecting opening 211, allowing the second liquid storage chamber 23 to communicate with the connecting opening 211, or preventing communication between them.

[0037] In this embodiment, by setting a first relative position A and a second relative position B of the seal 22 in the connecting channel 21, and controlling the sliding of the seal 22 in the connecting channel 21 by the connector 12, the seal 22 can seal or open the connecting channel 21.

[0038] Please refer to the following embodiment for the process of replenishing liquid from the second liquid storage device 20 to the first liquid storage device 10:

[0039] First, please refer to Figure 7 In the factory settings, the second liquid reservoir 20 has the seal 22 in the first relative position A, at which time the second liquid reservoir 20 is in a sealed state.

[0040] (1) Please refer to Figure 2When the second liquid storage component 20 and the first liquid storage component 10 enter a contact state, the connection opening 211 of the second liquid storage component 20 moves toward the liquid inlet opening 111 of the first liquid storage component 10 to gradually connect the connection channel 21 of the second liquid storage component 20 and the liquid inlet channel 11 of the first liquid storage component 10. During this process, the connector 12 extends into the connection channel 21 through the connection opening 211 and is able to contact the seal 22.

[0041] (2) Please refer to Figure 3 The second liquid storage component 20 and the first liquid storage component 10 are in the state where the connector 12 enters the liquid inlet channel 11. At this time, the connector 12 enters the connection channel 21 and contacts the seal 22, thereby driving the seal 22 to move from the first relative position A to the second relative position B.

[0042] (3) Please refer to Figure 4 When the second liquid storage component 20 and the first liquid storage component 10 are fully engaged, that is, the connector 12 has completely kept the seal 22 in the second relative position B. At this time, the connecting channel 21 is opened, and the atomizing matrix in the second liquid storage component 20 can enter the liquid inlet channel 11 through the connecting channel 21, thereby replenishing the atomizing matrix to the first liquid storage component 10.

[0043] (4) Fluid replacement complete. Please refer to [link / reference]. Figure 5 The second liquid storage component 20 and the first liquid storage component 10 enter a pre-separation state. At this time, the connector 12 is gradually pulled out of the connecting channel 21, while driving the sealing component 22 to move from the second relative position B to the first relative position A.

[0044] (5) Please refer to Figure 6 The second liquid reservoir 20 and the first liquid reservoir 10 become completely separated. At this time, the connector 12 has been completely pulled out from the connecting channel 21 and the seal 22 is moved to the first relative position A. At this time, the seal 22 in the first relative position A causes the second liquid reservoir 20 to become sealed again.

[0045] During use, the above operation can be repeated as needed to replenish the liquid. In this application, the second liquid reservoir 20 and the first liquid reservoir 10 are detachable and replaceable. Therefore, after the atomizing matrix in one second liquid reservoir 20 is exhausted, another second liquid reservoir 20 can be replaced for use.

[0046] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In one embodiment, the structure for realizing the first relative position A and the second relative position B within the connecting channel 21 is optimized as follows: a first limiting structure 212 and a second limiting structure 213 are provided within the connecting channel 21. The first limiting structure 212 is located at one end of the connecting channel 21 near the connecting opening 211, and the second limiting structure 213 is located at one end of the connecting channel 21 away from the connecting opening 211.

[0047] In this configuration, the sealing element 22 abuts against the first limiting structure 212 within the connecting channel 21, so that the sealing element 22 is in a first relative position A; the sealing element 22 abuts against the second limiting structure 213 within the connecting channel 21, so that the sealing element 22 is in a second relative position B.

[0048] In this embodiment, the first limiting structure 212 can be a protrusion disposed within the connecting channel 21 near the connecting opening 211. When the sealing member 22 moves within the connecting channel 21, it abuts against the first limiting structure 212, causing the sealing member 22 to be in a first relative position A. This allows the sealing member 22 to seal the connecting opening 211, thereby preventing leakage. Simultaneously, it also prevents the sealing member 22 from being pulled out when the connecting member 12 is withdrawn from the connecting channel 21.

[0049] In this embodiment, the second limiting structure 213 can also be a protrusion located within the connecting channel 21 near the second liquid storage chamber 23, or a blocking structure such as a protruding block or baffle, with the edge of the blocking structure connected to the edge of the opening of the connecting channel 21 facing the second liquid storage chamber 23. Through the second limiting structure 213, the atomized matrix in the second liquid storage chamber 23 can enter the connecting channel 21, and then enter the first liquid storage chamber 13 of the first liquid storage component 10 through the connecting channel 21 and the liquid inlet channel 11, thus achieving liquid replenishment. Simultaneously, the second limiting structure 213 also prevents the sealing component 22 from falling into the second liquid storage chamber 23 along the connecting channel 21.

[0050] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In one embodiment, the structure of how the connector 12 and the seal 22 cooperate to enable the seal 22 to switch from the second relative position B to the first relative position A will be described. Specifically, the seal 22 is provided with a groove 221 on the side near the connection opening 211, and the connector 12 is provided with a boss structure 121 at the end extending toward the liquid inlet opening 111; the boss structure 121 and the groove 221 are engaged to make the seal 22 move with the movement of the connector 12.

[0051] In this embodiment, when the connector 12 contacts the seal 22, it can push the seal 22 to move along the connecting channel 21 to the second relative position B. To enable the connector 12 to drive the seal 22 to move in the opposite direction during the process of withdrawing the connector 12 from the connecting channel 21, a boss structure 121 is provided at the end of the connector 12, and a corresponding groove 221 is provided on the seal 22. This is achieved through a snap-fit ​​mechanism. Specifically, when the connector 12 pushes the seal 22 to the second relative position B, as the connector 12 enters, the boss structure 121 at the end of the connector 12 can further engage with the groove 221 of the seal 22, thereby driving the seal 22 to move during the subsequent reverse movement.

[0052] In this embodiment, the boss structure 121 and the slot 221 are engaged, thereby causing the seal 22 to move to the first relative position A during the subsequent reverse movement.

[0053] In one embodiment, please refer to Figure 5 , Figure 6 and Figure 11 The boss structure 121 has a boss guide portion 1211 and a boss tail portion 1222. The boss guide portion 1211 is located at one end close to the seal 22, and the boss tail portion 1222 is located at one end away from the seal 22. The outer diameter of the boss tail portion 1222 is larger than the inner diameter of the inlet of the slot 221.

[0054] In this embodiment, the boss structure 121 is provided with a boss guide portion 1211. The size of the end face of the boss guide portion 1211 is less than or equal to the inner diameter of the inlet of the slot 221, so that the boss structure 121 can enter the slot 221 more smoothly. The boss structure 121 is provided with a boss tail portion 1222, and the outer diameter of the boss tail portion 1222 is limited to be greater than the inner diameter of the inlet of the slot 221, so that the boss structure 121 is not easy to disengage from the slot 221 during reverse movement, so as to realize that the connector 12 drives the seal 22 to move.

[0055] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In one embodiment, the seal 22 is made of an elastic seal, and the resistance between the groove 221 and the boss structure 121 is greater than the resistance between the seal 22 and the connecting channel 21, so that the connector 12 can drive the seal 22 to move in the opposite direction to the first relative position A.

[0056] In this embodiment, to further ensure that the seal 22 remains in the first relative position A when it is factory-set in the first relative position A, and when the connector 12 moves it back to the first relative position A, and does not detach from the first relative position A under the action of gravity or other external forces, the seal 22 is optimized as described above. First, the seal 22 is made of an elastic material to give it a certain degree of elasticity. Furthermore, the resistance between the groove 221 and the boss structure 121 is designed to be greater than the resistance between the seal 22 and the connecting channel 21, ensuring that the seal 22 can continuously overcome the resistance between the seal 22 and the connecting channel 21 during reverse movement. This allows it to remain in the first relative position A while in the first relative position A.

[0057] The resistance between the slot 221 and the boss structure 121 is greater than the resistance between the seal 22 and the connecting channel 21. This can be achieved by having the cross-sectional dimension of the seal 22 in the sliding direction of the connecting channel 21 be greater than the inner diameter of the connecting channel 21.

[0058] In another embodiment, the structure in which the connector 12 and the seal 22 are engaged so that the seal 22 can switch from the second relative position B to the first relative position A will be described. Specifically, one of the connector 12 and the seal 22 is a magnetic element and the other is a magnetic or metal element, so that the seal 22 moves with the movement of the connector 12 by magnetic attraction.

[0059] In this embodiment, the sealing element 22 is positioned in the first relative position A by means of magnetic attraction.

[0060] In this embodiment, the desired effect can be achieved by setting one of the connector 12 and the seal 22 as a magnetic component and the other as a magnetic or metallic component. Specifically, one is made of a magnetic material, such as a magnet, and the other is made of the same magnetic material (utilizing the principle of attraction between opposite poles of magnets) or a metallic material, such as a magnet or iron. Specifically, when the connector 12 contacts the seal 22, it can push the seal 22 to move along the connecting channel 21 towards the second relative position B. To enable the connector 12 to drive the seal 22 to move in the opposite direction during the process of the connector 12 being withdrawn from the connecting channel 21, the magnetic attraction between the connector 12 and the seal 22 is used to achieve the above requirement. Specifically, after the connector 12 pushes the seal 22 to the second relative position B, the seal 22 is tightly connected to the connector 12 through magnetic attraction, thereby driving the seal 22 to move during the subsequent reverse movement.

[0061] In this embodiment, a magnet is provided on the side wall of the connecting channel 21 near the first relative position A, so that the seal 22 is held in the second relative position B.

[0062] In this embodiment, similarly, in order to further ensure that the seal 22 is kept in the first relative position A when it is set at the factory and when the connector 12 drives it back to the first relative position A, and will not be separated from the first relative position A by gravity or other external forces, a magnet is provided on the side wall near the first relative position A. When the seal 22 is a magnetic component, the seal 22 is kept in the first relative position A by the attraction of opposite poles. When the seal 22 is a metal component, it is kept in the first relative position A directly by the magnetic attraction effect.

[0063] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the connecting channel 21 is provided with at least one communicating hole 214 on the side near the second limiting structure 213, and the connecting channel 21 communicates with the second liquid storage chamber 23 through the communicating hole 214.

[0064] When the seal 22 is in the second relative position B, the connecting hole 214 is misaligned with the seal 22, or the area of ​​the connecting hole 214 is greater than the area covered by the seal 22 covering the connecting hole 214.

[0065] In this embodiment, the specific structure for opening the connection opening 211 when the seal 22 is in the second relative position B is optimized. Specifically, at least one connecting hole 214 is provided on the side of the connection channel 21 near the second limiting structure 213 corresponding to the second relative position B. That is, a connecting hole 214 is provided on the side wall of the connection channel 21 so that the atomized matrix in the second liquid storage chamber 23 of the second liquid storage component 20 can enter the connection channel 21 and then enter the first liquid storage component 10. In order to ensure that the atomized matrix in the first liquid storage chamber 13 can enter the connection channel 21 when the seal 22 is in the second relative position B, the connecting hole 214 is misaligned with the seal 22 when the seal 22 is in the second relative position B, so that the seal 22 will not block the connecting hole 214. Alternatively, the area of ​​the connecting hole 214 is set to be larger than the coverage area of ​​the sealing component 22 covering the connecting hole 214, so that the sealing component 22 will not completely block the connecting hole 214, thereby keeping the connecting hole 214 unobstructed.

[0066] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In this embodiment, one end of the connector 12 extends out of the liquid inlet 111 in the direction of the liquid inlet 111, so that the connector 12 extends into the connection channel 21 through the connection opening.

[0067] In this embodiment, in order to further ensure that the connector 12 can enter the connection channel 21 and move the seal 22 to the second relative position B and remain in the second relative position B, one end of the connector 12 extending toward the liquid inlet opening 111 is configured to extend out of the liquid inlet opening 111. This ensures that the connector 12 can penetrate deep into the connection channel 21 and contact the seal 22, and that the connector 12 can push the seal 22 into and remain in the second relative position B when it extends into the connection channel 21.

[0068] In one embodiment, the structure of the second liquid reservoir 20 is optimized; please refer to [reference needed]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The second liquid storage component 20 is provided with a port structure 24, which is used to form the part of the connecting channel 21 near the connecting opening 211. The opening of the port structure 24 is the connecting opening 211.

[0069] The outer diameter of the nozzle structure 24 is smaller than the inner diameter of the liquid inlet channel 11.

[0070] Therefore, in this application, the connector 12 is first inserted into the liquid inlet channel 11 for positioning, and then the pipe structure 24 is inserted into the liquid inlet channel 11 to complete the connection between the first liquid storage component 10 and the second liquid storage component 20. The purpose of this arrangement is, on the one hand, to further improve the accuracy of the positioning of the connecting opening 211 and the liquid inlet opening 111, and on the other hand, to set part of the connecting channel 21 within the liquid inlet channel 11, thereby improving the tightness and sealing of the connection between the two.

[0071] In one embodiment, a sealing ring 25 is provided on the outer side of the nozzle structure 24 near the liquid inlet channel 11 to improve the tightness and sealing of the connection.

[0072] It should be noted that the port structure 24 of the second liquid reservoir 20 is not necessary in this application. The second liquid reservoir 20 in this application may also omit the port structure 24. Please refer to [reference needed]. Figure 8(Part C is a schematic diagram of the combined state, and part D is a schematic diagram of the separated state). It is only necessary to design the length of the connector 12 to match the length of the connecting channel 21.
