Abstract
Description
Technical Field
[0001] This application relates to the field of atomization technology, and in particular to a seal and its atomizer assembly. Background Technology
[0002] An atomizer is a device that heats and atomizes an aerogel matrix. The atomized aerogel matrix is then drawn in through the atomizer's airflow channels. Generally, the airflow inlet, i.e., the mouthpiece, is sealed to maintain airflow. During the atomizer's manufacturing process, reliability testing is required, which necessitates inverting the atomizer. During product transportation, atomizers may also need to be laid horizontally or inverted.
[0003] However, when the atomizer is inverted or laid flat, liquid can easily accumulate on the inner wall of the airway. This liquid can form a column along the length of the airway, causing splattering when the user removes the seal due to the internal negative pressure. Furthermore, splattering can still occur during inhalation of the atomizer due to the accumulated liquid on the airway wall. Utility Model Content
[0004] The embodiments of this application provide a seal and its atomizer assembly that can reduce liquid accumulation on the inner wall of the air passage, thereby reducing the occurrence of oil spillage.

[0037] 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.
[0038] Please refer to Figure 1 , Figure 2 and Figure 3 One embodiment of this application provides a sealing element 10 for sealing the air passage 200 of the atomizer body 20;
[0039] An airway 200 is formed inside the atomizer body 20. The atomizer body 20 is provided with a mouthpiece 210, which communicates with the airway 200. A portion of the seal 10 extends from the mouthpiece 210 into the airway 200, and another portion of the seal 10 blocks the mouthpiece 210. The section of the seal 10 extending into the airway 200 has a liquid storage structure 100.
[0040] In this embodiment, the sealing element 10 is a structural component that seals the air passage 200. One end of the sealing element 10 extends from the nozzle 210 of the atomizer into the air passage 200 and tightly engages with a section of the air passage 200 to achieve a seal. This tight engagement can be achieved by having one section of the sealing element 10 tightly fitted against the inner wall of the air passage 200, or by adding a sealing ring to one section of the sealing element 10, with the sealing ring tightly fitted against the inner wall of the air passage 200, or by an interference fit between one section of the sealing element 10 and the inner wall of the air passage 200. It should be noted that this embodiment does not limit the material of the sealing element 10; it can be an elastic material or a rigid material, as long as it can effectively seal the air passage 200.
[0041] In this embodiment, the liquid storage structure 100 is further explained. The liquid storage structure 100 is the main structure for achieving the effects of this application. Specifically, after the seal 10 extends into the air passage 200, since the seal 10 is located inside the air passage 200, the liquid storage structure 100 can absorb or store the liquid accumulated on the inner wall of the air passage 200. Specifically, it can be understood that the liquid storage structure 100 is a structure or material capable of absorbing or storing the liquid accumulated on the inner wall of the air passage 200. Through the absorption or storage of the liquid storage structure 100, the liquid accumulation on the inner wall of the air passage 200 is reduced, preventing the liquid on the inner wall of the air passage 200 from forming a liquid column along the length of the air passage 200, and ensuring that the absorbed or stored liquid is carried out of the air passage 200 when the seal 10 is pulled out. Specifically, when the liquid column is pulled out, it is easy for it to splash out of the air passage 200 along with the seal 10 due to the internal negative pressure, and it is easy for the splattered liquid to be sucked out during subsequent use of the atomizer.
[0042] It should be noted that the terms "oil" and "liquid" used in the description of "fly oil" in this application are descriptive terms for atomizing liquid, which is an atomizable aerogel matrix. In one example, the atomizing liquid is e-liquid.
[0043] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the liquid storage structure 100 consists of a plurality of first grooves 101 arranged along the direction of the seal 10 extending inward. The first grooves 101 are arranged on the outer peripheral surface of the seal 10 and are used to store the atomized liquid on the inner wall of the air passage 200.
[0044] In this embodiment, the first groove 101 can fit against the inner wall of the air passage 200, allowing the liquid accumulated on the inner wall of the air passage 200 to enter and be stored in the first groove 101. This prevents the atomized liquid from further accumulating on the inner wall of the air passage 200 and forming a liquid column. When the seal 10 is pulled out, the liquid stored in the first groove 101 can leave the air passage 200 as it is pulled out. It should be noted that this embodiment does not limit the shape of the first groove 101; the shape can be square, annular, or threaded, etc. In one example, such as... Figure 3 As shown, its first groove 101 is a threaded groove extending along the insertion direction of the seal 10. The machining of the threaded groove is relatively simple.
[0045] In one embodiment, such as Figure 1 and Figure 5 As shown, a liquid storage cotton 1011 is provided in the first groove 101. The liquid storage cotton 1011 is used to absorb and store the atomized liquid in the airway 200.
[0046] In this embodiment, the liquid storage cotton 1011 further absorbs and stores the accumulated liquid, thereby improving the stability of the liquid storage in the first groove 101.
[0047] In one embodiment, such as Figure 6 and Figure 7 As shown, the sealing element 10 includes a first section 11 and a second section 12 connected in sequence. The second section 12 is provided with a liquid storage structure 100 and is made of a material that can absorb and store the atomized liquid in the airway 200.
[0048] In this embodiment, the second segment 12 is provided with a liquid storage structure 100. This liquid storage structure 100 can be a structure disposed on the second segment 12 capable of storing accumulated liquid; it can also be a material disposed on the second segment 12 capable of absorbing and storing accumulated liquid, such as cotton or ceramic materials; or, the liquid storage structure 100 can be an integral part of the second segment 12, meaning the second segment 12 is made of a material capable of absorbing and storing the atomized liquid within the airway 200. This material can contact the accumulated liquid on the inner wall of the airway 200 when the seal 10 extends into the airway 200, absorbing and storing the liquid inside the material, thereby preventing the liquid from continuously accumulating on the inner wall of the airway 200 and forming a liquid column. In one example, the second segment 12 is liquid-retaining cotton.
[0049] In this embodiment, the seal 10 is designed in segments. The first segment 11 of the upper section is a conventional sealing segment, which can prevent the seal 10 from interfering with the front of the air passage 200 during assembly, thus preventing assembly difficulties. In one example, the first segment 11 is made of silicone material and is used to seal the nozzle 210.
[0050] In one example, the first segment 11 and the second segment 12 can be connected by splicing. In another example, the first segment 11 and the second segment 12 are integrally molded, that is, the first segment 11 and the second segment 12 are made of the same material, which can both be silicone material, and the second segment 12 is provided with a liquid storage structure 100, which is a liquid storage cotton.
[0051] In one embodiment, such as Figure 6 and Figure 7 As shown, the second segment 12 is provided with a plurality of second grooves 121 along the direction in which the seal 10 extends. The second grooves 121 are disposed on the outer peripheral surface of the second segment 12 and are used to store the atomizing liquid in the air passage 200.
[0052] In this embodiment, while the second segment 12 is made entirely of a material capable of absorbing and storing the atomized liquid in the airway 200, a plurality of second grooves 121 are further provided on the second segment 12, so that the liquid accumulated on the inner wall of the airway 200 can be stored in the second grooves 121 and then further absorbed and stored by the material body of the second segment 12.
[0053] In one example, the seal 10 is made of silicone material, and the first groove 101 is a groove structure disposed on the silicone material seal 10. In another example, the seal 10 includes a first segment 11 and a second segment 12 connected to each other, wherein the first segment 11 is made of silicone material, the second segment 12 is made of liquid-retaining cotton material, and the second groove 121 is a groove structure disposed on the second segment 12 of the liquid-retaining cotton material.
[0054] In one embodiment, the seal 10 is made of silicone. Among elastic materials, the silicone seal 10 can effectively seal the air passage 200 through its own deformation capacity, and silicone also has a longer lifespan compared to other elastic materials.
[0055] In one embodiment, the insertion length of the seal 10 into the airway 200 is greater than or equal to 90% of the length of the airway 200.
[0056] In this embodiment, the length of the seal 10 is increased to increase its proportion inside the airway 200 and reduce the gas volume in the airway 200. This reduces the internal exchange between the gas in the airway 200 and the atomized liquid in the liquid storage chamber of the atomizer, thereby reducing leakage.
[0057] In one embodiment, the length of the seal 10 extending into the air passage 200 is equal to 90% of the length of the air passage 200, or in another embodiment, the length of the seal 10 extending into the air passage 200 is equal to 100% of the length of the air passage 200, that is, the length of the seal 10 extending into the air passage 200 is equal to the length of the air passage 200.
[0058] In one embodiment, the liquid storage structure 100 occupies more than 50% of the length of the seal 10.
[0059] In this embodiment, the length of the liquid storage structure 100 is extended as much as possible so that the liquid storage structure 100 in the seal 10 can store as much liquid as possible, and thus bring out as much liquid as possible from the air passage 200 when it is pulled out.
[0060] In one embodiment, such as Figure 6 Part B and Figure 8 As shown, the first section 11 is provided with a sealing protrusion structure 111, which cooperates with the sealing groove structure 201 provided on the air passage 200 to block the air passage 200.
[0061] This embodiment further provides a sealing structure for the seal 10 and the air passage 200, that is, when mated, the sealing protrusion structure 111 is embedded in the sealing groove structure 201 to achieve the sealing of the air passage 200.
[0062] It should be noted that, in this embodiment, in order to ensure that the sealing member 10 can be smoothly pulled out of the airway 200 while sealing it, and to remove the accumulated liquid, there needs to be a gap between the outer surface of its liquid storage structure 100 and the inner wall of the airway 200. That is, the maximum diameter of any part of the liquid storage structure 100 is smaller than the inner diameter of the airway 200 at the corresponding position. This explanation is based on the assumption that the airway 200 is non-cylindrical and has a shape that gradually tapers from one end to the other.
[0063] Please refer to Figure 9 and Figure 10 Another embodiment of this application provides an atomizer assembly, including:
[0064] The atomizer body 20 has a mouthpiece 210 on it and an air passage 200 formed inside it, which is connected to the mouthpiece 210.
[0065] A seal 10, a portion of which extends from the nozzle 210 into the airway 200, and another portion of which blocks the nozzle 210, wherein the seal 10 is any of the seals described above.
[0066] Please continue to refer to this. Figure 9 The atomizer body 20 is also provided with an atomizing core 308. The atomizing core 308 is located at the end of the air passage 200 away from the mouthpiece 210. The atomizing core 308 is connected to the air passage 200. The sealing element and the air passage are located on the same side of the atomizing core.
[0067] In one embodiment, the seal 10 is located within the air passage 200 and above the atomizing core 308 (in the case of the atomizer body 20 being upright, the seal 10 is located below the atomizing core 308 when inverted). The insertion length of the seal 10 is designed to fill the air passage 200 as much as possible to bring it as close as possible to the atomizing core 308, thereby reducing leakage, since leakage typically originates from the atomizing core 308.
[0068] For a more detailed description of the atomizer body 20, please refer to [link / reference]. Figure 9 and Figure 10The atomizer body 20 includes an oil storage component 300, which includes an inner shell 301, an outer shell 302, a middle partition 303, a bottom seal 304, and a condensation chamber 305. The inner shell 301 forms an air passage 200, and a mouthpiece 210 is provided at the top of the inner shell 301. The inner shell 301, outer shell 302, and middle partition 303 enclose a liquid storage chamber 306. A bottom seal 304 is provided on the side of the middle partition 303 away from the air passage 200. The bottom seal 304 and the middle partition 303 enclose an atomizing chamber 307, which is connected to the liquid storage chamber 306. A liquid storage cotton 3071 is provided in the atomizing chamber 307, and an atomizing core 308 is provided in the liquid storage cotton. The atomizing core 308 is connected to the air passage 200. The condensation chamber 305 is located on the side of the bottom seal 304 away from the atomizing chamber 307 and is connected to the atomizing core 308. The condensation chamber 305 is equipped with a liquid storage cotton 3051.
[0069] In this system, the atomizing liquid in the storage chamber 306 enters the storage cotton 3071 in the atomizing chamber 307, and is heated and atomized by the atomizing core 308. The atomized gas flows through the air passage 200 towards the nozzle 210 and is sucked in. The storage cotton 3051 in the condensation chamber 305 absorbs the condensate generated during atomization, preventing it from obstructing the flow of the atomized gas and affecting safety. In one example, such as... Figure 2 As shown, the condensation chamber 305 contains two liquid storage cottons 3051 with different shapes.
[0070] Please continue to refer to this. Figure 9 The atomizer body 20 also includes a battery component 400, which includes a PCBA (Printed Circuit Board Assembly) 401 and a battery compartment 402. The battery compartment 402 is located on one side of the PCBA assembly 401, and the PCBA assembly 401 is connected to the atomizer core 308 and the battery in the battery compartment 402.
[0071] The PCBA assembly 401 is equipped with a control circuit to control the operation of the atomizer, while the battery in the battery compartment 402 is used to power the atomizer.
[0072] Please continue to refer to this. Figure 9 The atomizer core 308 also has an air inlet 500, which is connected to the condenser chamber 305. The air inlet 500 is equipped with an air inlet switch 501, which controls the air intake via a manual toggle switch.
[0073] Please continue to refer to this. Figure 9The atomizer core 308 also includes a side panel assembly 600, which is located on the same side as the oil reservoir 300 and the battery assembly 400. The side panel assembly 600 is provided with a display panel and / or a button control board, which is connected to the PCBA assembly 401.
[0074] Before use, the seal 10 and the air inlet switch 501 are closed simultaneously, sealing the air passage 200 completely. At this time, the atomizing liquid in the liquid storage chamber 306 only exchanges oil and gas with a small volume in the air passage 200. The volume of gas exchanged is sufficiently small, so the amount of oil leakage is also sufficiently small. When inverted, the atomizing liquid adhering to the inner wall of the air passage 200 is stored in the liquid storage structure of the seal 10. When the user pulls out the seal 10, the atomizing liquid is carried out by the silicone plug, effectively preventing liquid accumulation in the air passage 200 and preventing the user from inhaling accumulated liquid.
[0075] The above description is merely an embodiment of this application and does not limit the patent scope of this application.
