Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] In this specification, references to "one embodiment," "some embodiments," or "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0033] An electronic atomizing device is a product that transforms a liquid aerosol generating matrix into an aerosol through atomization or other means. When a user inhales, the aerosol flows with the airflow generated by the user's inhalation and exits the electronic atomizing device. The oil cup structure in the electronic atomizing device has a reservoir for storing the aerosol generating matrix, and the atomizing component is housed within the reservoir to heat the aerosol generating matrix within the oil cup structure to generate an aerosol.

[0034] In related technologies, the oil cup structure includes a sealing element for having a liquid storage chamber and sealing the liquid storage chamber. The process of injecting the aerosol generating matrix into the oil cup structure involves removing the sealing element from the oil cup structure, injecting the aerosol generating matrix into the liquid storage chamber, and then reinstalling the sealing element on the oil cup structure to seal the liquid storage chamber. During the sealing of the liquid storage chamber, the gas inside is compressed, thereby driving the aerosol generating matrix within the liquid storage chamber to be forced into the atomizing component, resulting in a significant risk of leakage.

[0035] In view of the above problems, this application provides an oil cup structure and an electronic atomizing device to solve the technical problem of high leakage risk.

[0036] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0037] Please refer to Figure 1 The first aspect of this application provides an oil cup structure 1, including a cup assembly 11 and a sealing assembly 12.

[0038] The cup assembly 11 has a liquid storage chamber 111 for storing the aerosol generation matrix; the cup assembly 11 includes an insertion part 113 disposed in the liquid storage chamber 111, and the insertion part 113 is provided with a first sealing sub-hole 1121 communicating with the liquid storage chamber 111; the sealing assembly 12 includes a liquid absorption expansion group 122, which is inserted into the first sealing sub-hole 1121, and the liquid absorption expansion group 122 is configured to expand to seal the first sealing sub-hole 1121 after contacting the aerosol generation matrix in the liquid storage chamber 111.

[0039] In the oil cup structure 1 provided in this embodiment, before the liquid absorption expansion assembly 122 expands to close the first sealing sub-hole 1121, there is a gap within the liquid absorption expansion assembly 122 and / or a gap between the liquid absorption expansion assembly 122 and the first sealing sub-hole 1121, allowing gas in the liquid storage chamber 111 to escape, thereby preventing gas from compressing the aerosol generation matrix in the liquid storage chamber 111 and reducing the risk of leakage. After the liquid absorption expansion assembly 122 sealing assembly 12 expands to close the first sealing sub-hole 1121, the liquid storage chamber 111 is sealed to prevent leakage of the aerosol generation matrix in the liquid storage chamber 111.

[0040] It should be noted that the liquid-absorbing and swelling assembly 122 in this embodiment is made of a liquid-absorbing and swelling material, which enables the liquid-absorbing and swelling assembly 122 to absorb and swell.

[0041] Liquid-absorbing and swelling materials include, but are not limited to, water-absorbing and swelling silicone, superabsorbent polymers, and water-absorbing and swelling rubber.

[0042] It should be noted that the expansion of the liquid absorption expansion group 122 after contacting the aerosol generation matrix in the liquid storage cavity 111 means that the liquid absorption expansion group 122 will adsorb the aerosol generation matrix after contacting the aerosol generation matrix in the liquid storage cavity 111 and expand to close the first sealing sub-hole 1121.

[0043] As can be seen from the above analysis, when the oil cup structure 1 of this application closes the liquid storage chamber 111, some of the aerosol generating matrix in the liquid storage chamber 111 will be adsorbed into the liquid absorption expansion group 122. The aerosol generating matrix adsorbed into the liquid absorption expansion group 122 cannot be atomized, resulting in a waste of the aerosol generating matrix.

[0044] In view of the above issues, please refer to Figure 1 In some embodiments, the outer wall surface of the insertion portion 113 and the inner wall surface of the liquid storage cavity 111 enclose a second sealing sub-hole 1122, and the first sealing sub-hole 1121 and the second sealing sub-hole 1122 constitute a sealing hole 112. The sealing assembly 12 also includes a first sealing member 121 and a liquid absorption expansion assembly 122, wherein the first sealing member 121 is inserted into the second sealing sub-hole 1122 and closes the second sealing sub-hole 1122.

[0045] Please refer to Figure 2 In some embodiments, the cup assembly 11 includes a cup 114 and a second seal 115. The second seal 115 is disposed at one of the openings of the cup 114, and the liquid storage cavity 111 is formed by the second seal 115 and the cup 114. The insertion part 113 is disposed at the opening of the cup 114 opposite to the opening of the second seal 115.

[0046] In the above embodiment, the opening of the cup 114 opposite to the second sealing member 115 is a sealing hole 112. An insertion part 113 is disposed at the opening, and a first sealing sub-hole 1121 is formed on the insertion part 113. The second sealing sub-hole 1122 is formed by the outer wall surface of the insertion part 113 and the inner wall surface of the liquid storage chamber 111. The second sealing member 115 is inserted into the second sealing sub-hole 1122 to seal it. The liquid absorption expansion assembly 122 is housed within the first sealing sub-hole 1121 and seals the first sealing sub-hole 1121 after expansion.

[0047] The above-mentioned design makes the structure of each component of the cup assembly 11 relatively simple and the cost low, and also makes it easy to disassemble and assemble the cup assembly 11.

[0048] It should be noted that the material of the second seal 115 can be rubber, silicone, etc.

[0049] It should be noted that, when the liquid absorption swelling rate (the percentage increase in volume of an object after absorbing liquid) is constant, the larger the volume of the liquid-absorbing swelling object, the larger the volume of liquid absorbed, and the smaller the volume of the liquid-absorbing swelling object, the smaller the volume of liquid absorbed.

[0050] In the above embodiments, the sealing assembly 12 is divided into a first sealing element 121 and a liquid-absorbing expansion group 122, and the sealing hole 112 is divided into a first sealing sub-hole 1121 and a second sealing sub-hole 1122. The second sealing sub-hole 1122 is closed by the first sealing element 121. After the liquid-absorbing expansion group 122 adsorbs the aerosol-generating matrix and expands to close the first sealing sub-hole 1121, the first sealing sub-hole 1121 is closed by the liquid-absorbing expansion group 122. By reducing the volume of the structure made of liquid-absorbing expansion material in the sealing assembly 12 of this application embodiment, the aerosol-generating matrix adsorbed by the sealing assembly 12 can be reduced as much as possible, thereby minimizing the waste of the aerosol-generating matrix.

[0051] When using the sealing assembly 12 in the above embodiment to seal the liquid storage chamber 111, the first sealing member 121 is first inserted into the second sealing sub-hole 1122 to seal the second sealing sub-hole 1122, and then the liquid absorption expansion assembly 122 is placed in the first sealing sub-hole 1121. During the process of placing the liquid absorption expansion assembly 122 in the first sealing sub-hole 1121 and during the expansion of the liquid absorption expansion assembly 122, the gas in the liquid storage chamber 111 can be discharged from the gap between the liquid absorption expansion assembly 122 and the first sealing sub-hole 1121 and / or from the gap in the liquid absorption expansion assembly 122.

[0052] When assembling the oil cup structure 1 of the above embodiment, the first sealing member 121 is first inserted into the second sealing sub-hole 1122 to seal the second sealing sub-hole 1122, and then the aerosol generating matrix is ​​injected into the liquid storage cavity 111. During the injection of the aerosol generating matrix, the cup assembly 11 can be tilted to facilitate the aerosol generating matrix filling the liquid storage cavity 111.

[0053] Please refer to Figure 2 and Figure 3 In some embodiments, the liquid absorption expansion assembly 122 includes a first stop portion 1221, which is located on the side of the insertion portion 113 away from the liquid storage cavity 111, and in the radial direction of the first sealing sub-hole 1121, the first stop portion 1221 protrudes from the inner wall of the first sealing sub-hole 1121.

[0054] With the above configuration, the insertion part 113 can support the first stop part 1221, allowing the liquid absorption expansion assembly 122 to be mounted on the cup cylinder 114. On one hand, before the liquid absorption expansion assembly 122 expands to close the first sealing sub-hole 1121, the insertion part 113 supports the first stop part 1221, limiting the position of the liquid absorption expansion assembly 122. This eliminates the need for assembly personnel to hold the liquid absorption expansion assembly 122 by hand or for clamping equipment, reducing the assembly difficulty of the oil cup structure 1. On the other hand, the insertion part 113 supporting the first stop part 1221 prevents the liquid absorption expansion assembly 122 from being completely contained within the first sealing sub-hole 1121, facilitating disassembly during subsequent maintenance.

[0055] Please refer to Figure 2 and Figure 3 The expansion and absorption assembly includes a sealing plug 1222 and a sealing sleeve 1223. The sealing sleeve 1223 is inserted into the first sealing sub-hole 1121, and the sealing plug 1222 is inserted into the sealing sleeve 1223. The sealing plug 1222 is configured to expand to abut against the inner wall of the sealing sleeve 1223 after contacting the aerosol-generated matrix in the liquid storage chamber 111, and / or, the sealing sleeve 1223 is configured to expand to fill the gap between the inner wall of the first sealing sub-hole 1121 and the sealing plug 1222 after contacting the aerosol-generated matrix in the liquid storage chamber 111.

[0056] In the above embodiments, the liquid-absorbing expansion assembly 122 is divided into a sealing plug 1222 and a sealing sleeve 1223, and the sealing plug 1222 and / or the sealing sleeve 1223 are structures made of liquid-absorbing expansion material. This can further reduce the volume of a single structure made of liquid-absorbing expansion material in the sealing assembly 12 in the embodiments of this application, and can minimize the aerosol generation matrix adsorbed by the sealing assembly 12, thereby minimizing the waste of aerosol generation matrix.

[0057] In the above embodiment, the first stop portion 1221 is provided in the sealing sleeve 1223.

[0058] It should be noted that when the sealing sleeve 1223 is configured to expand to fill the gap between the inner wall of the first sealing sub-hole 1121 and the sealing plug 1222 after contacting the aerosol generated matrix in the liquid storage cavity 111, the process of sealing the first sealing sub-hole 1121 using the liquid absorption expansion assembly 122 can be as follows: first, the sealing sleeve 1223 is placed in the first sealing sub-hole 1121, and the first stop part 1221 is mounted on the insertion part 113 to prevent the sealing sleeve 1223 from falling into the liquid storage cavity 111. Then, the sealing plug 1222 is placed in the sealing sleeve 1223, and the gas in the liquid storage cavity 111 can be discharged from the gap between the sealing sleeve 1223 and the sealing plug 1222 and from the gap between the inner wall of the first sealing sub-hole 1121 and the sealing sleeve 1223.

[0059] It should be noted that when the sealing plug 1222 is configured to expand to abut against the inner wall of the sealing sleeve 1223 after contacting the aerosol generating matrix in the liquid storage cavity 111, and when the sealing sleeve 1223 is configured to expand to fill the gap between the inner wall of the first sealing sub-hole 1121 and the sealing plug 1222 after contacting the aerosol generating matrix in the liquid storage cavity 111, the process of sealing the first sealing sub-hole 1121 using the liquid absorption expansion assembly 122 can refer to the above process.

[0060] It should be noted that when the sealing plug 1222 is configured to expand to abut against the inner wall of the sealing sleeve 1223 after contacting the aerosol matrix generated in the liquid storage chamber 111, the process of sealing the first sealing sub-hole 1121 using the liquid absorption expansion assembly 122 can be as follows: first, the sealing sleeve 1223 is inserted into the first sealing sub-hole 1121, and then the sealing plug 1222 is placed in the sealing sleeve 1223. During the process of placing the sealing plug 1222 in the sealing sleeve 1223 and during the expansion of the sealing plug 1222, the gas in the liquid storage chamber 111 can be discharged from the gap between the sealing sleeve 1223 and the sealing plug 1222.

[0061] Please refer to Figure 3 In some embodiments, the sealing plug 1222 includes a second stop portion 1224, which is located on the side of the sealing sleeve 1223 away from the liquid storage cavity 111, and protrudes from the inner wall of the sealing sleeve 1223 in the radial direction of the sealing sleeve 1223.

[0062] With the above configuration, the sealing sleeve 1223 can support the second stop 1224, allowing the sealing plug 1222 to be mounted on the sealing sleeve 1223. On one hand, before the sealing sleeve 1223 and / or the sealing plug 1222 expand to close the first sealing sub-hole 1121, the sealing sleeve 1223 supports the second stop 1224, limiting the position of the sealing plug 1222. This eliminates the need for assembly personnel to hold the sealing plug 1222 by hand or for clamping equipment, reducing the assembly difficulty of the oil cup structure 1. On the other hand, the sealing sleeve 1223 supporting the second stop 1224 prevents the sealing plug 1222 from being completely contained within the sealing sleeve 1223, facilitating disassembly during subsequent maintenance.

[0063] Please refer to Figure 4 The second aspect of this application provides an electronic atomizing device, including an atomizing component 2 and an oil cup structure 1 as described in the first aspect embodiment.

[0064] The atomizing component 2 is housed in the liquid storage chamber 111, and the atomizing component 2 is used to heat the aerosol generating matrix to generate aerosol.

[0065] By applying the oil cup structure 1 of the first aspect embodiment described above to an electronic atomizing device, the risk of leakage in the electronic atomizing device is reduced.

[0066] Please refer to Figure 4 In some embodiments, the atomizing component 2 includes an air guide tube 21, a fixing base 22, and an atomizing core 23. The fixing base 22 is connected to the cup tube component 11, the air guide tube 21 is connected to the sealing component 12, and the atomizing core 23 is located between the fixing base 22 and the air guide tube 21. Both the fixing base 22 and the air guide tube 21 are in communication with the atomizing core 23.

[0067] In the above embodiment, the second seal 115 in the cup assembly 11 is provided with an air inlet 1151, and the first seal 121 in the sealing assembly 12 is provided with an air outlet 1211. The air inlet 1151, the fixing seat 22, the atomizing core 23, the air guide tube 21 and the air outlet 1211 are connected in sequence to form an atomizing air channel.

[0068] In the above embodiment, the atomizing core 23 is connected to the liquid storage chamber 111. The atomizing core 23 can heat the aerosol in the liquid storage chamber 111 to generate a matrix and generate aerosol in the atomizing air channel.

[0069] Please refer to Figure 4 In some embodiments, the atomizing component 2 further includes a liquid storage element 24, which is sleeved on the periphery of the atomizing core 23.

[0070] In the above embodiment, the liquid storage component 24 is used to guide the aerosol generating matrix in the liquid storage chamber 111 to the atomizing core 23. The atomizing core 23 contacts the aerosol generating matrix through the liquid storage component 24. This not only controls the supply speed of the aerosol generating matrix, but also controls the contact area between the atomizing core 23 and the aerosol generating matrix. This ensures that when the contact area of ​​the aerosol generating matrix in the liquid storage chamber 111 decreases, the entire area of ​​the atomizing core 23 can still contact the aerosol generating matrix through the liquid storage component 24, thus preventing some of the atomizing core 23 from dry burning due to insufficient contact with the aerosol generating matrix.

[0071] Please refer to Figure 4 In some embodiments, the atomizing component 2 further includes a partition plate 25, which is located on one side of the atomizing core 23. A first liquid storage chamber 1111 is formed between the partition plate 25 and the atomizing core 23. A second liquid storage chamber 1112 is formed on the side of the partition plate 25 away from the atomizing core 23. A liquid supply window (not shown in the figure) is provided on the partition plate 25 to connect the first liquid storage chamber 1111 and the second liquid storage chamber 1112. The liquid storage component 24 is housed in the first liquid storage chamber 1111.

[0072] In the above embodiment, both the atomizing core 23 and the liquid storage component 24 are disposed within the first liquid storage chamber 1111, and the second liquid storage chamber 1112 can replenish the aerosol generating matrix to the first liquid storage chamber 1111. Furthermore, when replenishing the aerosol generating matrix to the electronic atomizing device, it is only necessary to remove the expansion suction assembly or the sealing plug 1222 within the expansion suction assembly, and then replenish the aerosol generating matrix into the liquid storage chamber 111. The partition plate 25 separates the first liquid storage chamber 1111 and the second liquid storage chamber 1112, ensuring that the aerosol generating matrix replenished into the second liquid storage chamber 1112 does not affect the position and connection relationship of the atomizing core 23 and the liquid storage component 24 within the first liquid storage chamber 1111, thus not affecting the subsequent normal operation of the electronic atomizing device.

[0073] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
