Detailed implementation manners

[0032] The present application will be further described in detail below in conjunction with the specific embodiments and the accompanying drawings. Similar elements in different embodiments are denoted by related similar element numbers. In the following embodiments, many details are described to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by excessive description. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0033] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment, and do not mean to be the necessary composition and / or sequence.

[0034] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0035] An atomizing device generally consists of a liquid storage device and an atomizing device. For example, the atomizing device can be products such as electronic cigarettes and aromatherapy diffusers. The liquid storage device stores an atomizing matrix in liquid form that can be heated and atomized to generate an aerosol. The atomizing device can heat and atomize the atomizing matrix to generate an aerosol. Usually, the atomizing device and the liquid storage device are fixedly connected and assembled before shipment, making it difficult to replace the liquid storage device with the used-up atomizing matrix. And some liquid storage devices in atomizing devices adopt an open structure, and when it is necessary to replace the atomizing matrix, it can be refilled into the liquid storage device. However, when different components of atomizing matrix need to be refilled, the aerosol generated by the previously remaining atomizing matrix and the later refilled atomizing matrix will have a flavor mixing problem.

[0036] In response to this, the present application adopts an atomizing device composed of an independent liquid storage device and an atomizing device. The liquid storage device can store different types of atomizing matrices. When the user needs to replace with different types of atomizing matrices, only the liquid storage device containing the corresponding type of atomizing matrix needs to be assembled with the atomizing device, so as to avoid the problem of flavor mixing of the generated aerosol. However, after the atomizing device is assembled with the liquid storage device and the atomizing core of the atomizing device is inserted into the atomizing channel of the liquid storage device, this assembly method has strict sealing requirements, and there is an assembly gap between the atomizing core and the atomizing channel. In this way, it is easy to leak the atomizing matrix between the atomizing core and the atomizing channel due to the need to conduct the atomizing matrix, thereby affecting the user experience.

[0037] In view of the above problems, the present application provides a liquid storage device and an atomizing device, which prevent the atomizing matrix from leaking by sealing both ends of the atomizing channel, so as to improve the user experience.

[0038] Embodiment 1

[0039] See Figures 1-4 As shown, the liquid storage device 100 provided in this embodiment includes: a liquid storage chamber 10, a liquid storage member 20, and a sealing assembly 30.

[0040] The inside of the liquid storage chamber 10 has an aerosol channel 1010 and independent first and second chambers 101 and 102. The first chamber 101 is used to store an atomizing matrix in liquid form that can be atomized to generate aerosol. The first chamber 101 surrounds and forms the aerosol channel 1010. In other words, the aerosol channel 1010 can be formed by structures such as a pipe provided in the first chamber 101, so that the aerosol channel 1010 and the first chamber 101 are independent structures, and the inner cavity of the pipe forms the aerosol channel 1010. The aerosol channel 1010 communicates with the second chamber 102, and moreover, the aerosol channel 1010 penetrates through the liquid storage chamber 10 to communicate with the outside, and the aerosol channel 1010 can output the generated aerosol to the outside of the liquid storage chamber 10. A liquid passing hole 103 is provided between the first chamber 101 and the second chamber 102. The atomizing matrix stored in the first chamber 101 can flow into the second chamber 102 through the liquid passing hole 103 under its own gravity. The liquid storage chamber 10 is also provided with a socket 104, and the socket 104 forms a channel opening through which the atomizing core in the atomizing device can be inserted into the second chamber 102. For specific details, please refer to the subsequent embodiments.

[0041] In one embodiment, a partition portion 105 is provided inside the liquid storage chamber 10. The partition portion 105 divides the inner cavity of the liquid storage chamber 10 into independent first and second chambers 101 and 102, and the liquid passing hole 103 is formed on the partition portion 105.

[0042] Combined with Figures 2-4As shown, the partition part 105 is formed into a "mouth" - shaped structure with an open end at one end in cross - section. Among them, the open end is connected to the inner wall of the liquid storage chamber 10, so that the "mouth" - shaped partition part 105 and the inner wall of the liquid storage chamber 10 enclose a second chamber 102.

[0043] In some embodiments, the partition part 105 and the interior of the liquid storage chamber 10 are of an integral structure. Of course, in other embodiments, the partition part 105 can also be of a split - type structure with the interior of the liquid storage chamber 10, and the specific choice can be made according to actual needs.

[0044] The liquid storage member 20 is arranged in the second chamber 102. The liquid storage member 20 is preferably a liquid storage cotton made of materials such as cotton or fiber, which has a certain porosity. It can adsorb the atomization matrix by its own hydrophilicity and lipophilicity. The atomization matrix flowing into the second chamber 102 under its own gravity through the liquid - passing hole 103 is adsorbed and stored by the liquid storage member 20. The liquid storage member 20 is provided with an atomization channel 21. The aerosol channel 1010, the atomization channel 21, and the socket 104 are connected in sequence. After assembling the present liquid storage device 100 with the atomization device, the atomization core in the atomization device can be inserted into the atomization channel 21 through the socket 104. Then the liquid storage member 20 can transmit the stored atomization matrix to the atomization core, and the atomization matrix can be atomized by heating through the atomization core to generate aerosol, and the aerosol is output to the outside of the liquid storage chamber 10 through the aerosol channel 1010.

[0045] In this embodiment, the setting of the liquid - passing hole 103 enables the atomization matrix stored in the first chamber 101 to slowly flow into the second chamber 102, and the setting of the liquid storage member 20 enables the atomization matrix to be slowly transmitted to the atomization core, avoiding a large amount of atomization matrix being conducted to the atomization core and not being completely heated and atomized.

[0046] The atomization core in the atomization device is inserted into the atomization channel 21 through the socket 104. Since there is an assembly gap between the atomization core and the atomization channel 21, the atomization matrix is likely to leak due to the existence of this assembly gap.

[0047] In this regard, a sealing assembly 30 is further provided in the liquid storage device 100 provided in this application. The sealing assembly 30 includes an upper seal 31 and a lower seal 32. The upper seal 31 is disposed at one end of the aerosol passage 1010 close to the atomization passage 21, and the lower seal 32 is disposed at the socket 104. After the atomization core is inserted into the atomization passage 21 through the socket 104, a part of the atomization core is located at one end of the aerosol passage 1010 close to the atomization passage 21, and a part of the atomization core is located at the socket 104. In other words, there are assembly gaps between the atomization core and one end of the aerosol passage 1010 close to the atomization passage 21 and between the atomization core and the socket 104. The arrangements of the upper seal 31 and the lower seal 32 can cooperate with the atomization core through the upper seal 31 and the lower seal 32 to seal the assembly gaps between the atomization core and one end of the aerosol passage 1010 close to the atomization passage 21 and between the atomization core and the socket 104 for the atomization passage 21 respectively.

[0048] In this embodiment, both the upper seal 31 and the lower seal 32 are made of silica gel and have a certain elasticity, and can seal the assembly gaps between the atomization core and one end of the aerosol passage 1010 close to the atomization passage 21 and between the atomization core and the socket 104 through their own elastic actions.

[0049] An atomization seat is usually provided in the atomization device, and the atomization core is installed on the atomization seat. After the atomization core of the atomization device is inserted into the atomization passage 21 through the socket 104, a part of the atomization core extends into the aerosol passage 1010, and the atomization seat is located at the socket 104. Therefore, there are assembly gaps between the atomization core and the aerosol passage 1010 and between the atomization seat and the socket 104, which are likely to cause leakage of the atomization matrix. Therefore, the assembly gap between the atomization core inserted into the atomization passage 21 through the socket and the aerosol passage 1010 can be sealed by the upper seal 31, and the assembly gap between the atomization seat and the socket 104 can be sealed by the lower seal 32. One end of the aerosol passage 1010 close to the atomization passage 21 and the socket 104 are respectively located outside both ends of the atomization passage 21. Thus, the assembly gaps between one end of the aerosol passage 1010 close to the atomization passage 21 and the atomization core and between the socket 104 and the atomization seat can be sealed respectively through the cooperation of the upper seal 31 and the lower seal 32 with the atomization core, thereby avoiding leakage of the atomization matrix from the atomization passage 21.

[0050] Such as Figure 2 and Figure 4As shown, on one side of the first chamber 101 facing the second chamber 102, there is a first extension portion 1011 extending towards the second chamber 102. The first extension portion 1011 has an extension channel 1012. On the outer wall of the second chamber 102, there is a second extension portion 1021 extending towards the first extension portion 1011. The second extension portion 1021 has an extension groove 1022. At the bottom of the extension groove 1022, there is a through hole 1023 communicating with the second chamber 102. The first extension portion 1011 is inserted into the extension groove 1022. Among them, between the extension channel 1012 and the extension groove 1022 is one end of the aerosol channel 1010 close to the atomization channel 21. The upper seal 31 is arranged between the first extension portion 1011 and the extension groove 1022.

[0051] In a specific embodiment, the upper seal 31 has a first upper annular seal portion 311. The first upper annular seal portion 311 is arranged between the end of the first extension portion 1011 and the bottom of the extension groove 1022, so as to seal the assembly gap between the end of the first extension portion 1011 and the bottom of the extension groove 1022, such that the extension channel 1012, the inner circumference of the first upper annular seal portion 311, and the through hole 1023 form the aerosol channel 1010.

[0052] After sealing the assembly gap between the end of the first extension portion 1011 and the bottom of the extension groove 1022 through the first upper annular seal portion 311, since there is also an assembly gap between the outer wall of the first extension portion 1011 and the inner wall of the extension groove 1022, therefore, in this embodiment, the upper seal 311 also has an annular extension seal portion 312. The annular extension seal portion 312 is formed by extending from the outer periphery of the first upper annular seal portion 311 in a direction away from the first upper annular seal portion 311. The annular extension seal portion 312 is arranged between the outer wall of the first extension portion 1011 and the inner wall of the extension groove 1022.

[0053] Continue to refer to Figures 2-4 As shown, the lower seal 32 has a first lower annular seal portion 321. The first lower annular seal portion 321 is arranged at the socket 104. After inserting the atomization core of the atomization device into the atomization channel 21 through the socket 104, the assembly gap with the atomization seat can be sealed through the first lower annular seal portion 321.

[0054] In a specific embodiment, inside the liquid storage chamber 10, there is also a first positioning portion 131 located around the second chamber 102. The first positioning portion 131 is at the outer periphery of the socket 104. The lower seal 32 also has a first positioning and mating portion 322. The first positioning and mating portion 322 is arranged at the outer periphery of the first lower annular seal portion 321. The first positioning portion 131 and the first positioning and mating portion 322 cooperate with each other to position the lower seal 32, which can prevent the lower seal 32 from generating radial movement and improve the connection stability with the atomization seat.

[0055] In one embodiment, the first positioning portion 131 is a convex structure, and the first positioning and mating portion 322 is a groove structure. When the first positioning portion 131 and the first positioning and mating portion 322 cooperate with each other, the convex can be inserted into the groove, so as to limit the radial direction of the lower seal 32 and prevent it from generating radial movement.

[0056] See Figure 3 and Figure 4 As shown, for the convenience of processing the liquid storage device 100 provided by the present application, the liquid storage chamber 10 includes a first chamber body 11, a first top cover 12 and a first bottom cover 13. One end of the first chamber body 11 is provided with a first open end 111, and the other end of the first chamber body 11 is provided with a second open end 112. The second open end 112 enables the second chamber 102 to communicate with the outside. The first top cover 12 is buckled at the first open end 111, and the first bottom cover 13 is buckled on the side of the first chamber body 11 where the second open end 112 is provided. The aforementioned socket 104 is opened on the first bottom cover 13 and communicates with the second chamber 102. The first positioning portion 131 is provided on the side of the first bottom cover 13 facing the second chamber 102, and the lower seal 32 is located between the second open end 112 and the first bottom cover 13.

[0057] In this embodiment, the first top cover 12 and the first open end 111 can be fixedly connected by means of snap connection or the like, and the partition portion 105 is provided inside the first chamber body 11, and the aforementioned first extension portion 1011 is formed on the first top cover 12.

[0058] To ensure the sealing performance between the first open end 111 of the first chamber body 11 and the first top cover 12, the liquid storage chamber 10 further includes a sealing ring 14, and the sealing ring 14 is provided between the first top cover 12 and one end of the first chamber body 11 close to the first open end 111.

[0059] Embodiment Two

[0060] This embodiment provides a liquid storage device 100. The main difference between this liquid storage device 100 and that in Embodiment One lies in the structures of the upper seal, the lower seal and the partition portion. For details, please refer to the following embodiments.

[0061] See Figures 5-8 As shown, the liquid storage device 100 provided in this embodiment includes: a liquid storage chamber 10, a liquid storage member 20 and a sealing assembly 30.

[0062] The interior of the liquid storage chamber 10 has an aerosol passage 1010 and independent first and second chambers 101 and 102. The first chamber 101 is used to store an atomization matrix in liquid form that can be atomized to generate aerosol. The first chamber 101 surrounds and forms the aerosol passage 1010. In other words, the aerosol passage 1010 can be formed by structures such as pipes arranged in the first chamber 101, so that the aerosol passage 1010 and the first chamber 101 are independent structures, and the inner cavity of the pipe forms the aerosol passage 1010. This aerosol passage 1010 communicates with the second chamber 102, and moreover, this aerosol passage 1010 penetrates through the liquid storage chamber 10 to communicate with the outside, and this aerosol passage 1010 can output the generated aerosol to the outside of the liquid storage chamber 10. A liquid through-hole 103 is provided between the first chamber 101 and the second chamber 102. The atomization matrix stored in the first chamber 101 can flow into the second chamber 102 through the liquid through-hole 103 under the action of its own gravity. The liquid storage chamber 10 is also provided with a socket 104, and this socket 104 forms a channel opening for the atomization core in the atomization device to be inserted into the second chamber 102. For details, please refer to the subsequent embodiments.

[0063] In one embodiment, a partition 105 is provided inside the liquid storage chamber 10. This partition 105 divides the inner cavity of the liquid storage chamber 10 into independent first and second chambers 101 and 102, and the liquid through-hole 103 is formed on the partition 105.

[0064] Combined Figures 6-8 As shown, the partition 105 is formed into a plate-like structure, and this plate-like partition 105 divides the inner cavity of the liquid storage chamber 10 into the first chamber 101 and the second chamber 102.

[0065] In some embodiments, the partition 105 and the interior of the liquid storage chamber 10 are of an integral structure. Of course, in other embodiments, the partition 105 can also be of a split structure with the interior of the liquid storage chamber 10, and specific selection can be made according to actual needs.

[0066] In this embodiment, the partition 105 is a plate-like structure. The shapes and sizes of the first chamber 101 and the second chamber 102 formed by dividing the inner cavity of the liquid storage chamber 10 by this plate-like partition 105 are different from those of the first chamber 101 and the second chamber 102 in the first embodiment.

[0067] The liquid storage member 20 is disposed in the second chamber 102. The liquid storage member 20 is preferably a liquid storage cotton made of materials such as cotton or fiber, has a certain porosity, and can adsorb the atomization matrix by its own hydrophilicity and lipophilicity. The atomization matrix flowing into the second chamber 102 under its own gravity through the liquid passing hole 103 is adsorbed and stored by the liquid storage member 20. The liquid storage member 20 is provided with an atomization channel 21, and the aerosol channel 1010, the atomization channel 21, and the socket 104 are connected in sequence. After assembling the present liquid storage device 100 with the atomization device, the atomization core in the atomization device can be inserted into the atomization channel 21 through the socket 104, and the liquid storage member 20 can transfer the stored atomization matrix to the atomization core. Then, the atomization matrix can be atomized by heating through the atomization core to generate aerosol, and the aerosol is output to the outside of the liquid storage chamber 10 through the aerosol channel 1010.

[0068] In this embodiment, the setting of the liquid passing hole 103 enables the atomization matrix stored in the first chamber 101 to slowly flow into the second chamber 102, and the setting of the liquid storage member 20 enables the atomization matrix to be slowly transferred to the atomization core, avoiding a large amount of atomization matrix being conducted to the atomization core and not being completely heated and atomized.

[0069] The atomization core in the atomization device is inserted into the atomization channel 21 through the socket 104. Since there is an assembly gap between the atomization core and the atomization channel 21, the atomization matrix is likely to leak due to the existence of this assembly gap.

[0070] In response to this, a sealing assembly 30 is further provided in the liquid storage device 100 provided in the present application. The sealing assembly 30 includes an upper seal 31 and a lower seal 32. The upper seal 31 is disposed at one end of the aerosol channel 1010 close to the atomization channel 21, and the lower seal 32 is disposed at the socket 104. After the atomization core is inserted into the atomization channel 21 through the socket 104, part of the atomization core is located at one end of the aerosol channel 1010 close to the atomization channel 21, and part of the atomization core is located at the socket 104. In other words, there are assembly gaps between the atomization core and one end of the aerosol channel 1010 close to the atomization channel 21 and between the atomization core and the socket 104. The settings of the upper seal 31 and the lower seal 32 can cooperate with the atomization core through the upper seal 31 and the lower seal 32 to seal the assembly gaps between the atomization core and one end of the aerosol channel 1010 close to the atomization channel 21 and between the atomization core and the socket 104 for the atomization channel 21 respectively.

[0071] In this embodiment, both the upper seal 31 and the lower seal 32 are made of materials such as rubber or silica gel, have a certain elasticity, and can seal the assembly gaps between the atomization core and one end of the aerosol channel 1010 close to the atomization channel 21 and between the atomization core and the socket 104 through their own elastic actions.

[0072] An atomizing device usually has an atomizing base, and an atomizing core is installed on the atomizing base. After the atomizing core of the atomizing device is inserted into the atomizing channel 21 through the socket 104, a part of the atomizing core extends into the aerosol channel 1010, while the atomizing base is located at the socket 104. Therefore, there are assembly gaps between the atomizing core and the aerosol channel 1010, and between the atomizing base and the socket 104, which are likely to cause leakage of the atomizing matrix. Therefore, the assembly gap between the atomizing core inserted into the atomizing channel 21 through the socket and the aerosol channel 1010 can be sealed by the upper seal 31, and the assembly gap between the atomizing base and the socket 104 can be sealed by the lower seal 32. One end of the aerosol channel 1010 close to the atomizing channel 21 and the socket 104 are respectively located outside both ends of the atomizing channel 21. Therefore, the upper seal 31 and the lower seal 32 are used to seal the assembly gaps between one end of the aerosol channel 1010 close to the atomizing channel 21 and the atomizing core, and between the socket 104 and the atomizing base respectively, so as to avoid leakage of the atomizing matrix from the atomizing channel 21.
