Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and particularly to liquid storage devices and aerosol generation apparatus. Background Technology

[0002] The prior art provides a typical aerosol generating device, which includes a separate liquid reservoir, an atomizer, and a main unit. The liquid reservoir is used to store a certain volume of liquid matrix, and the atomizer is equipped with a heating element for receiving the liquid matrix and evaporating the liquid matrix by heating.

[0003] In some designs, the reservoir and atomizer typically establish liquid flow through a liquid guide column with guide holes. Once the reservoir is installed in the atomizer, it can consistently supply and replenish the liquid matrix to the heating element during both use and non-use periods. However, this is particularly problematic in designs where the reservoir and main unit are not removable. The guide column cannot be repeatedly inserted and removed, preventing the liquid path from being severed and potentially leading to liquid matrix leakage. Furthermore, the reservoir cannot be refilled after assembly. Utility Model Content

[0004] To solve the problem that the reservoir cannot be refilled after assembly.

[0005] One embodiment of this application provides a liquid reservoir, comprising: The first housing defines a first liquid reservoir for storing a liquid matrix; The base defines an outlet for discharging liquid matrix from the first liquid storage chamber and an inlet for injecting liquid matrix into the first liquid storage chamber. A liquid output component is disposed on the side of the base opposite to the first liquid storage chamber; The liquid output component is rotatable relative to the first housing between a first position and a second position. When the liquid output component is in the first position, the liquid outlet and the liquid inlet are opened; when the liquid output component is in the second position, the liquid outlet and the liquid inlet are closed.

[0006] In some embodiments, the reservoir includes a first seal disposed between the base and the liquid output element.

[0007] In some embodiments, the first sealing member is provided with a first through hole and a second through hole. When the liquid output member is in the first position, the first through hole and the liquid outlet are connected, and the second through hole and the liquid inlet are connected.

[0008] In some embodiments, the first seal has a first rib and a second rib on the side facing the liquid output member, the first rib defining a limiting groove for the liquid outlet in the rotation path, and the second rib defining a limiting groove for the liquid inlet in the rotation path.

[0009] In some embodiments, the first rib includes an annular first sub-rib and a second sub-rib connected to the first sub-rib, the first through hole being located within the area enclosed by the first sub-rib; and / or the first through hole avoiding the area enclosed by the second sub-rib.

[0010] In some embodiments, the second rib includes an annular third sub-rib and a fourth sub-rib connected to the third sub-rib, and the second through hole is located in the area enclosed by the third sub-rib; and / or the second through hole avoids the area enclosed by the fourth sub-rib.

[0011] In some embodiments, the liquid output device includes at least one hollow liquid guide column with a liquid guide hole. When the liquid output device is in the first position, the liquid guide column is aligned with the liquid outlet, and the liquid guide hole is connected to the first liquid storage cavity.

[0012] In some embodiments, the liquid output component is provided with an injection hole, and when the liquid output component is in the first position, the injection hole and the inlet are in liquid communication.

[0013] In some embodiments, the base includes a first sliding portion, and the liquid output component includes a second sliding portion movably connected to the first sliding portion, wherein one of the first sliding portion and the second sliding portion provides an arcuate sliding trajectory for the other.

[0014] In some embodiments, the base includes a limiting groove, and the liquid output member includes a limiting portion that can be embedded in the limiting groove, the limiting groove defining a path for the liquid output member to rotate in the first position and the second position.

[0015] In some embodiments, the limiting groove includes a first groove and a second groove, the first groove being used to provide tactile feedback when the liquid output component rotates to the first position, and the second groove being used to provide tactile feedback when the liquid output component rotates to the second position.

[0016] In some embodiments, the number of liquid outlets is two, and one of the liquid outlets has an annular wall surrounding the liquid outlet and extending into the first liquid storage cavity on the side facing the liquid storage cavity.

[0017] In some embodiments, the reservoir includes a second seal, which is at least partially disposed between the first housing and the base.

[0018] One embodiment of this application provides an aerosol generating device, including an atomizer and the aforementioned liquid reservoir. The atomizer defines a second liquid reservoir for storing a liquid matrix. When the liquid output component is in the first position, the liquid outlet is opened, thereby connecting the first liquid reservoir and the second liquid reservoir.

[0019] In some embodiments, the atomizer includes a bracket for defining the second liquid reservoir, the bracket having a third seal disposed on one side facing the liquid reservoir, the third seal blocking the injection hole on the liquid output member when the liquid output member is in the first position.

[0020] The liquid reservoir base provided in this application has a liquid inlet. When the liquid output component is in the first position, both the liquid inlet and the liquid outlet are open simultaneously. This allows the liquid matrix to be injected after the reservoir is assembled, improving production efficiency. Furthermore, during liquid injection, air in the first storage chamber can be discharged through the liquid outlet, preventing liquid matrix overflow. In addition, when the liquid output component is in the second position, both the liquid inlet and the liquid outlet are closed simultaneously, eliminating the need for a liquid injection sealing plug to prevent leakage.

[0028] One embodiment of this application provides a liquid reservoir 10, such as... Figures 1-5As shown, the device includes a first housing 1, a base 2, and a liquid output component 3. The first housing 1 defines a first liquid storage chamber 11 for storing a liquid matrix. The base 2 defines an outlet 21 for discharging the liquid matrix outward from the first liquid storage chamber 11 and an inlet 22 for injecting the liquid matrix into the first liquid storage chamber 11. The liquid output component 3 is disposed at the inlet on the side of the base 2 opposite to the first liquid storage chamber 11. The liquid output component 3 is rotatable relative to the first housing 1 between a first position and a second position. When the liquid output component 3 is in the first position, both the outlet 21 and the inlet 22 are simultaneously opened; when the liquid output component 3 is in the second position, both the outlet 21 and the inlet 22 are simultaneously closed.

[0029] The base 2 of the liquid reservoir 10 provided in this application has a liquid inlet 22. When the liquid output component 3 is in the first position, the liquid inlet 22 and the liquid outlet 21 are opened simultaneously, allowing the liquid matrix to be injected after the liquid reservoir 10 is assembled, thus improving production efficiency. Furthermore, during liquid injection, air in the first liquid storage chamber 11 can be discharged through the liquid outlet 21, preventing liquid matrix overflow. In addition, when the liquid output component 3 is in the second position, the liquid inlet 22 and the liquid outlet 21 are closed simultaneously, eliminating the need for a liquid injection sealing plug to prevent leakage from the liquid reservoir 10.

[0030] In one embodiment of this application, such as Figure 2 As shown, the liquid reservoir 10 includes a first seal 41, which is disposed between the base 2 and the liquid output component 3. It can prevent the liquid matrix from leaking between the base 2 and the liquid output component 3, so that the liquid output component 3 can still maintain good sealing performance during the rotation of the first housing 1.

[0031] In one embodiment of this application, the liquid matrix may comprise a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it may be a liquid containing non-tobacco substances. The liquid matrix may comprise water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include areca nut extract, menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but are not limited thereto. Flavorings contain ingredients that can provide the user with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited thereto. Based on the different properties of the liquid matrix, aerosol matrix reservoirs can be used in different fields, such as medical applications and electronic aerosol atomization.

[0032] In one embodiment of this application, such as Figure 6As shown, the first sealing member 41 is provided with a first through hole 411 and a second through hole 412. When the liquid output member 3 is in the first position, the first through hole 411 and the liquid outlet 21 are connected, and the second through hole 412 and the liquid inlet 22 are connected, so that the liquid matrix in the first liquid storage chamber 11 can flow out through the liquid outlet 21, or the liquid matrix can be injected into the first liquid storage chamber 11 through the liquid inlet 22. In one embodiment of this application, the first sealing member 41 is provided with a first through hole 411 and a second through hole 412. When the liquid output member 3 is in the first position, the first through hole 411 and the liquid outlet 21 overlap at least partially, and the second through hole 412 and the liquid inlet 22 overlap at least partially, so that the liquid matrix in the first liquid storage chamber 11 can flow out through the liquid outlet 21, or the liquid matrix can be injected into the first liquid storage chamber 11 through the liquid inlet 22.

[0033] In one embodiment of this application, such as Figure 7 As shown, the first sealing member 41 is provided with a first rib 413 and a second rib 414 on the side facing the liquid output member 3. The first rib 413 defines a limiting groove for the liquid outlet 21 on the rotation path, and the second rib 414 defines a limiting groove for the liquid inlet 22 on the rotation path, so that the liquid matrix in the first liquid storage chamber 11 will not leak from the base 2 and the liquid output member 3 during the rotation of the liquid output member 3 relative to the first housing 1.

[0034] In one embodiment of this application, the first rib 413 includes an annular first sub-rib 4131 and a second sub-rib 4132 connected to the first sub-rib 4131. The first through hole 411 is located within the area enclosed by the first sub-rib 4131, ensuring that the liquid matrix in the first liquid storage chamber 11 does not leak between the base 2 and the liquid output component 3 during rotation relative to the first housing 1. In another embodiment of this application, the first through hole 411 avoids the area enclosed by the second sub-rib 4132, so that when the liquid output component 3 is in the second position, the second sub-rib 4132 closes the liquid outlet 21.

[0035] In one embodiment of this application, the second rib 414 includes an annular third sub-rib 4141 and a fourth sub-rib 4142 connected to the third sub-rib 4141. The second through hole 412 is located within the area enclosed by the third sub-rib 4141, ensuring that the liquid matrix in the first liquid storage chamber 11 does not leak between the base 2 and the liquid output component 3 during rotation relative to the first housing 1. In another embodiment of this application, the second through hole 412 avoids the area enclosed by the fourth sub-rib 4142, so that when the liquid output component 3 is in the second position, the fourth sub-rib 4142 closes the inlet 22.

[0036] In one embodiment of this application, the first seal 41 may be made of silicone.

[0037] In one embodiment of this application, there are two liquid outlets 21, and correspondingly, there are also two first ribs 413. In another embodiment of this application, there is one liquid inlet 22, and the first seal 41 includes two second ribs 414, so that the liquid output component 3 maintains force balance during rotation.

[0038] In one embodiment of this application, such as Figure 10 As shown, the liquid output component 3 includes at least one hollow liquid guide column 31 with a liquid guide hole 32. When the liquid output component 3 is in the first position, the liquid guide column 31 is aligned with the liquid outlet 21, and the liquid guide hole 32 communicates with the first liquid storage chamber 11. During the production of the liquid storage device 10, the first housing 1, the base 2, and the liquid output component 3 can be assembled into a semi-finished product. Then, by rotating the liquid guide column 31, the liquid outlet 21 and the liquid inlet 22 can be opened or closed simultaneously, allowing liquid to be injected after the liquid storage device 10 is assembled, thus improving production efficiency.

[0039] In one embodiment of this application, the liquid guiding hole 32 is located on the side of the liquid guiding column 31 away from the first liquid storage chamber 11, that is, the liquid guiding hole 32 is located on the bottom wall of the liquid guiding column 31.

[0040] In one embodiment of this application, there are two liquid guiding columns 31. When the liquid matrix in the liquid guiding hole 32 of one of the liquid guiding columns 31 flows out of the first liquid storage chamber 11, the air pressure in the first liquid storage chamber 11 decreases. At this time, external air can enter the first liquid storage chamber 11 through the liquid guiding hole 32 of the other liquid guiding column 31, thereby preventing the liquid matrix in the first liquid storage chamber 11 from being unable to flow out due to the decrease in air pressure.

[0041] In one embodiment of this application, the diameter of the liquid guiding hole 32 is smaller than the inner diameter of the hollow portion of the liquid guiding column 31. The smaller diameter of the liquid guiding hole 32 relative to the inner diameter of the hollow portion of the liquid guiding column 31 results in a slower outflow rate of the liquid matrix from the hollow portion of the liquid guiding column 31.

[0042] In one embodiment of this application, the liquid output component 3 is provided with a liquid injection hole 33. When the liquid output component 3 is in the first position, the liquid injection hole 33 and the liquid inlet 22 are connected.

[0043] In one embodiment of this application, such as Figures 8-9 As shown, the first housing 1 includes a first snap-fit ​​portion 12, and the base 2 includes a second snap-fit ​​portion 23. The first housing 1 and the base 2 are snap-fit ​​connected. In one embodiment of this application, one of the first snap-fit ​​portion 12 and the second snap-fit ​​portion 23 is a buckle, and the other is a slot. The first snap-fit ​​portion 12 and the second snap-fit ​​portion 23 are snap-fitted to fix the first housing 1 to the base 2.

[0044] In one embodiment of this application, the first housing 1 includes a mounting groove 14, and the base 2 includes a positioning part 26 disposed in the mounting groove 14. In one embodiment of this application, there are two positioning parts 26, located on both sides of the second snap-fit ​​part 23. When the base 2 is installed on the first housing 1, the positioning parts 26 and the mounting groove 14 can be used to position the base 2 and the first housing 1, and can prevent the base 2 and the first housing 1 from rotating relative to each other, making the connection between the base 2 and the first housing 1 more secure.

[0045] In one embodiment of this application, the base 2 includes a first sliding portion 24, and the liquid output component 3 includes a second sliding portion 34 movably connected to the first sliding portion 24. One of the first sliding portion 24 and the second sliding portion 34 provides an arc-shaped sliding trajectory for the other. In another embodiment of this application, one of the first sliding portion 24 and the second sliding portion 34 is a slider, and the other is a groove.

[0046] In one embodiment of this application, such as Figure 9 As shown, the base 2 includes a limiting groove 25, and the liquid output component 3 includes a limiting part 35 that can be embedded in the limiting groove 25. The limiting groove 25 defines the path of rotation of the liquid output component 3 in a first position and a second position.

[0047] In one embodiment of this application, the limiting groove 25 includes a first groove 251 and a second groove 252. The first groove 251 is used to provide tactile feedback of the liquid output component 3 when rotated to a first position, and the second groove 252 is used to provide tactile feedback of the liquid output component 3 when rotated to a second position. When the liquid output component 3 is in the first position, the limiting component 35 is located in the first groove 251; when the liquid output component 3 is in the second position, the limiting component 35 is located in the second groove 252.

[0048] In one embodiment of this application, there are two liquid outlets 21. One of the liquid outlets 21 has an annular wall 27 surrounding the liquid outlet 21 and extending into the first liquid storage cavity 11 on the side facing the liquid outlet 21. The annular wall 27 can guide bubbles to rise into the first liquid storage cavity 11 and prevent bubbles from accumulating near the liquid outlet 21. The annular wall 27 allows the liquid matrix in the first liquid storage cavity 11 to flow out of the first liquid storage cavity 11 stably from the liquid outlet 21 without the annular wall 27. The liquid outlet with the annular wall 27 can serve as an air inlet channel to prevent the air pressure in the first liquid storage cavity 11 from being too low, so that the liquid matrix in the first liquid storage cavity 11 can flow out smoothly.

[0049] In one embodiment of this application, such as Figure 11 As shown, the reservoir 10 includes a second seal 42, which is at least partially disposed between the first housing 1 and the base 2.

[0050] One embodiment of this application provides an aerosol generating device 100, such as... Figures 13-14 As shown, it includes an atomizer 20 and the aforementioned liquid reservoir 10. The atomizer 20 has a second liquid reservoir 61 defined inside for storing a liquid matrix. When the liquid output component 3 is in the first position, the liquid outlet 21 is opened, thereby connecting the first liquid reservoir 11 and the second liquid reservoir 61.

[0051] In one embodiment of this application, the atomizer 20 includes a second housing 5. When the first housing 1 rotates relative to the second housing 5, the liquid output member 3 switches between a first position and a second position, and the liquid outlet 21 of the base 2 switches between open and closed.

[0052] In one embodiment of this application, such as Figure 15 As shown, the atomizer 20 includes a bracket 6 for defining a second liquid storage chamber 61. A third seal 43 is provided on the side of the bracket 6 facing the liquid storage chamber 10. When the liquid output component 3 is in the first position, the third seal 43 blocks the injection hole 33 located on the liquid output component 3. After the liquid storage chamber 10 is installed into the atomizer 20, the injection hole 33 of the liquid output component 3 is blocked by the third seal 43, preventing the liquid matrix in the first liquid storage chamber 11 from leaking from the injection hole 33.

[0053] In one embodiment of this application, such as Figure 18 As shown, the third seal 43 includes a third rib 431, which surrounds the injection hole 33 to prevent the liquid matrix in the injection hole 33 from leaking between the liquid output member 3 and the support 6. In one embodiment of this application, the third seal 43 also includes a third through hole 432 through which the liquid guide column 31 can pass.

[0054] In one embodiment of this application, the aerosol generating device 100 includes a main unit 30, which provides electrical power to the atomizer 20.

[0055] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
