[0030] Please refer to Figure 1 , Figure 1 It is a structural schematic diagram of an electronic atomization device according to one or more embodiments of the present application.

[0031] The electronic atomization device 1 can convert an aerosol-generating substrate into aerosol-like smoke by heating or other means. The user inhales the aerosol by drawing in from the mouthpiece of the electronic atomization device 1. The aerosol-generating substrate can be a liquid substrate. The electronic atomization device 1 includes a liquid reservoir 2, which can store a liquid substrate, etc., to facilitate atomization by the electronic atomization device 1.

[0032] Please refer to Figure 2-Figure 5 , Figure 2 is a first structural schematic diagram of a liquid reservoir according to one or more embodiments of the present application; Figure 3 is an exploded view of a liquid reservoir according to one or more embodiments of the present application; Figure 4 is a second structural schematic diagram of a liquid reservoir according to one or more embodiments of the present application; Figure 5 Yes Figure 4 The schematic cross-sectional view of the reservoir along the AA direction is shown.

[0033] To solve the above problems, the present application provides a liquid reservoir 2, which includes: a shell 10, a sealing assembly 20 and a child lock assembly 30; the sealing assembly 20 is arranged in the shell 10, and the sealing assembly 20 and the shell 10 cooperate to form a liquid storage chamber 21, and the liquid storage chamber 21 is used to accommodate a liquid matrix; the child lock assembly 30 is arranged on the side of the sealing assembly 20 away from the liquid storage chamber 21 in the first direction x1 in which the sealing assembly 20 and the liquid storage chamber 21 are arranged, and the child lock assembly 30 has a welding surface 31 in contact with the inner wall of the shell 10, and the welding surface 31 is used to form a welding portion 311 so that the child lock assembly 30 is welded and fixed to the shell 10.

[0034] The sealing assembly 20 and the child lock assembly 30 may both be located within the housing 10. For example, the housing 10 may be formed with a receiving space, within which the sealing assembly 20 and the child lock assembly 30 may both be disposed. The sealing assembly 20 and the housing 10 cooperate to form a liquid storage chamber 21, which contains a liquid matrix. The sealing assembly 20 can seal the liquid matrix, reducing the risk of leakage. The child lock assembly 30 is disposed on a side of the sealing assembly 20 facing away from the liquid storage chamber 21 in the first direction x1. The child lock assembly 30 contacts the inner wall of the housing 10 via a welding surface 31 and is welded and secured to the housing 10 via a welding portion 311 on the welding surface 31. It is understood that the welding portion 311 can be formed at the junction of the welding surface 31 and the inner wall of the housing 10 by methods such as laser welding. Illustratively, when forming the weld 311 via laser welding, the laser power can be greater than or equal to 4W and less than or equal to 6W, and optionally, the laser power can be 5W. The laser spotting time can be greater than or equal to 0.25 seconds and less than or equal to 0.35 seconds, and optionally, the laser spotting time can be 0.3 seconds. In some applications, the laser wavelength can be 915nm. Optionally, the weld 311 can be a weld point, weld particles, or the like. The weld 311 can be welded to the inner wall of the housing 10 with a certain bonding force, making it difficult for a child to break the child lock assembly 30 and access the sealing assembly 20. In some applications, there can be multiple welds 311, such as two, three, four, or more, and multiple welding surfaces 31 can also be provided. For example, the child lock assembly 30 has two opposing welding surfaces 31, each of which can be provided with two welds 311.

[0035] According to the above embodiment, the child lock assembly 30 is welded and fixed to the housing 10 via the weld portion 311, making it difficult for children to separate the child lock assembly 30 from the housing 10 by conventional means, such as bare hands, thereby protecting the sealing assembly 20 through the child lock assembly 30. This reduces the risk of children directly contacting or damaging the sealing assembly 20, causing the liquid matrix in the liquid storage chamber 21 to leak or even be accidentally ingested by the child.

[0036] In some embodiments, the housing 10 is a transparent housing 10 that can transmit laser light to form the weld 311. It is understood that when laser welding is used to form the weld 311, the laser light can be transmitted through the transparent housing 10 into the interior of the housing 10, thereby allowing the weld surface 31 to receive the laser light and form the weld 311 on the weld surface 31. The material of the transparent housing 10 may include, but is not limited to, PCTG (polyethylene terephthalate-1,4-cyclohexanedimethanol), PC (polycarbonate), and the like.

[0037] In some embodiments, the thickness of the shell 10 is greater than or equal to 1 mm and less than or equal to 1.5 mm. The thickness of the shell 10 can be between 1 mm and 1.5 mm. For example, the thickness of the shell 10 can be 1 mm, 1.2 mm, 1.3 mm, 1.35 mm, 1.5 mm, and so on. It is understandable that, correspondingly, the penetration depth of the laser can also be greater than or equal to 1 mm and less than or equal to 1.5 mm. In some application scenarios, the penetration depth of the laser is set corresponding to the thickness of the shell 10. For example, when the thickness of the shell 10 is 1.5 mm, the penetration depth of the laser can also be 1.5 mm. As a result, it is convenient for the laser to penetrate the shell 10 to form the weld portion 311 on the weld surface 31, thereby reducing the energy loss when the laser penetrates the shell 10.

[0038] In some embodiments, the housing 10 has an opening 11 that connects the interior of the housing 10 with the outside world, allowing the child lock assembly 30 to be exposed through the opening 11. The opening 11 is spaced apart from the sealing assembly 20 in the first direction x1. It will be appreciated that the opening 11 facilitates a user's access to the interior of the housing 10 and contact with the child lock assembly 30 during normal use. For example, an adult user can access the child lock assembly 30 through the opening 11 and remove it manually or with a tool. After removal, the child lock assembly 30 can be removed from the housing 10 through the opening 11, allowing the adult user to normally use the liquid reservoir 2. Thus, the opening 11 facilitates the removal of the child lock assembly 30 by an average adult user, thereby allowing access to the liquid reservoir 2.

[0039] In some embodiments, the bonding force between the weld 311 and the inner wall of the housing 10 is greater than a preset threshold. When the weld 311 is subjected to a force in the first direction x1 that is greater than the bonding force, it detaches from the inner wall of the housing 10, allowing the child lock assembly 30 to exit the opening 11. The bonding force of the weld 311 can be adjusted by the laser frequency and duration of the laser welding process. The bonding force of the weld 311 can be greater than a preset threshold, which can be the maximum force that a typical child can apply to the child lock assembly 30 in the first direction x1 using conventional means, such as bare hands. For example, the bonding force of the weld 311 can be greater than the maximum pulling force in the first direction x1 generated by a child pinching and pulling the child lock assembly 30 with their fingers. It is understood that in typical applications, it is difficult for a child to exert a force greater than the bonding force on the weld 311 in the first direction x1 through their own strength, thereby detaching the weld 311 from the inner wall of the housing 10 and allowing the child lock assembly 30 to exit the opening 11. In other embodiments, the bonding force between the weld portion 311 and the inner wall of the housing 10 may be less than the maximum force that a typical adult user can apply to the child lock assembly 30 in the first direction x1. This facilitates adult users to remove the child lock assembly 30 for proper use of the liquid reservoir 2, reducing the risk of children damaging the child lock assembly 30 and contacting the sealing assembly 20, thereby causing leakage of the liquid medium.

[0040] In some embodiments, the preset threshold is greater than or equal to 40 N and less than or equal to 60 N. For example, the preset threshold may include, but is not limited to, 40 N, 45 N, 50 N, 55 N, 60 N, etc. Optionally, the preset threshold may be 50 N. It is understood that when the preset threshold is 50 N, the bonding force between the weld portion 311 and the inner wall of the housing 10 may be greater than 50 N, such as 51 N, 52 N, 55 N, etc.

[0041] In some embodiments, the child lock assembly 30 includes a first sealing portion 32 and a locking member 33 that are interconnected. The first sealing portion 32 is disposed on a side of the sealing assembly 20 facing away from the liquid storage chamber 21, and the locking member 33 is disposed on a side of the first sealing portion 32 facing the opening 11. A weld 311 is disposed on the locking member 33. The weld 311 is disposed on the locking member 33, and the child lock assembly 30 is welded and fixed to the housing 10 via the locking member 33. The first sealing portion 32 can be oil-sealing silicone and can provide a sealed protection for the sealing assembly 20, further reducing the risk of leakage of the liquid matrix through the sealing assembly 20.

[0042] In some embodiments, the locking member 33 is formed with two opposing disassembly slots 331 in a second direction x2 perpendicular to the first direction x1. The disassembly slots 331 communicate with the opening 11. The two disassembly slots 331 may originate on opposite sides of the locking member in the second direction x2, with the notches of the disassembly slots 331 communicating with the opening 11. It is understood that an adult user can insert a finger or a tool through the opening 11 into the two opposing disassembly slots 331, thereby gripping the locking member 33 and applying a pulling force in the first direction x1, thereby removing the child lock assembly 30. For example, to manually remove the child lock assembly 30, an adult user can insert at least two fingers, such as a thumb and index finger, into the two disassembly slots 331 through the opening 11. This facilitates the user's application of pulling force to the locking member 33, thereby removing the child lock assembly 30, reducing the risk of the child lock assembly 30 being unable to withstand the force, preventing the adult user from removing the lock.

[0043] In some embodiments, the locking member 33 has a locking portion 332 extending in the first direction x1, and the first sealing portion 32 has a locking groove 321. The locking portion 332 is inserted into the locking groove 321 to fix the first sealing portion 32 relative to the locking member 33. The number of locking portions 332 can be multiple, and the number of locking grooves 321 can be arranged to correspond to the number of locking portions 332. The locking member 33 and the first sealing portion 32 can be fixedly connected via the locking portion 332 and the locking groove 321. It is understood that when the child lock assembly 30 is disassembled, the welded portion 311 is separated from the inner wall of the housing 10 and exits the housing 10 through the opening 11 under the action of a pulling force along the first direction x1. The locking member 33 and the first sealing portion 32 are fixedly connected via the locking portion 332 and the locking groove 321, facilitating the first sealing portion 32 to exit the housing 10 together with the locking member 33, thereby exposing the sealing assembly 20 through the opening 11.

[0044] In some embodiments, the sealing assembly 20 includes a liquid guide 22 having a liquid channel 221 connecting the liquid storage chamber 21 with the outside world. When the child lock assembly 30 is in the locked state, the liquid channel 221 is blocked by a first sealing portion 32. The liquid guide 22 may include a hollow oil column extending along the first direction x1, thereby forming the liquid channel 221. The liquid channel 221 may have a liquid guide hole 222 connecting the liquid channel 221 with the outside world. It is understood that before the child lock assembly 30 is removed, the child lock assembly 30 may block the liquid guide hole 222. After the child lock assembly 30 is removed, the liquid guide 22 can guide the liquid matrix in the liquid storage chamber 21 to the liquid guide hole 222 through the liquid guide hole 222, and then exit the liquid storage chamber 21 through the liquid guide hole 222, thereby enabling normal use of the liquid reservoir 2. When the child lock assembly 30 is in the locked state, the first sealing portion 32 blocks the liquid channel 221, isolating the liquid channel 221 from the outside world. This facilitates the normal oil discharge of the liquid reservoir 2 after the child lock assembly 30 is removed, while reducing the risk of liquid matrix leakage when the child lock assembly 30 is locked.

[0045] In some embodiments, the sealing assembly 20 further includes a second sealing portion 23, which is disposed on a side of the liquid-guiding member 22 proximal to the liquid storage chamber 21. The second sealing portion 23 has a through-hole 231, which communicates with the liquid-guiding channel 221. The second sealing portion 23 can directly contact the liquid matrix within the liquid storage chamber 21. The second sealing portion 23 can also be made of oil-sealing silicone, allowing the liquid matrix within the liquid storage chamber 21 to enter the liquid-guiding channel 221 through the through-hole 231. Thus, the second sealing portion 23 can reduce the risk of liquid matrix flowing out of the liquid storage chamber 21 through locations other than the liquid-guiding channel 221, such as assembly gaps. Simultaneously, the second sealing portion 23 can cooperate with the first sealing portion 32 to seal on both sides of the liquid-guiding member 22, thereby reducing the risk of liquid matrix leakage and improving the reliability of the liquid reservoir 2.

[0046] In summary, the present application provides a liquid reservoir 2, comprising: a housing 10, a sealing assembly 20, and a child lock assembly 30. The sealing assembly 20 is disposed within the housing 10, and the sealing assembly 20 and the housing 10 cooperate to form a liquid storage chamber 21 for containing a liquid matrix. The child lock assembly 30 is disposed on a side of the sealing assembly 20 facing away from the liquid storage chamber 21, in a first direction x1 in which the sealing assembly 20 and the liquid storage chamber 21 are aligned. The child lock assembly 30 has a welding surface 31 that contacts the inner wall of the housing 10, forming a welding portion 311 to weld the child lock assembly 30 to the housing 10. Through the above-described embodiment, the child lock assembly 30 is welded to the housing 10 via the welding portion 311, thereby protecting the sealing assembly 20. This reduces the risk of leakage of the liquid matrix in the liquid storage chamber 21, or even accidental ingestion, caused by direct contact or damage to the sealing assembly 20 by children. Compared to other liquid reservoirs, the liquid reservoir 2 provided by the present application is safer.
