Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

[0025] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0026] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0027] Currently, whether it's a top-mounted or bottom-mounted storage bottle, the atomizing matrix in the storage bottle is first transported to the storage chamber, and then the storage chamber continuously supplies the atomizing core. However, this design generally has the following problems: 1) Since the storage bottle needs to be installed inside the electronic atomizing device, and the atomizing matrix needs to be output from the bottle opening to the storage chamber, a liquid guide needs to be installed at the bottle opening. The liquid guide will affect the smoothness of the atomizing matrix flowing out of the bottle opening, thus affecting the supply speed of the atomizing matrix; 2) When the storage bottle is installed inside the electronic atomizing device, since the bottle opening is open and the storage chamber is not sealed, the atomizing matrix is ​​prone to leakage during use.

[0028] This embodiment provides a liquid storage device 100. Please refer to [reference needed]. Figure 1-2 The liquid storage device 100 includes a first housing 110, a first sealing assembly 120, and a first valve component 130.

[0029] Please refer to Figure 1-2 and Figure 5The first housing 110 has a first accommodating cavity 111, an atomizing air passage 112, and a nozzle 113. One end of the atomizing air passage 112 communicates with the nozzle 113, and the other end extends into the first accommodating cavity 111. A first sealing assembly 120 is disposed within the first accommodating cavity 111 and defines a liquid storage space 1111 with the first accommodating cavity 111. The liquid storage space 1111 is used to store the atomizing matrix. The first sealing assembly 120 is provided with an injection hole 121 and a first through hole 122. The injection hole 121 is used to inject the atomizing matrix into the liquid storage space 1111. The first sealing assembly 120 includes an injection plug 123, which is used to seal the injection hole 121. The first valve component 130 is movably disposed at one end of the atomizing air passage 112 that extends into the first receiving cavity 111, so that the first valve component 130 can move axially along the atomizing air passage 112 under the action of external force, so as to insert into or move away from the first through hole 122. When the first valve component 130 is inserted into the first through hole 122, the first through hole 122 is blocked; when the first valve component 130 leaves the first through hole 122, the first through hole 122 is opened, and the atomizing matrix in the liquid storage space 1111 can flow out of the liquid storage space 1111 from the first through hole 122.

[0030] This application defines the liquid storage space 1111 by using the first sealing component 120 and the first accommodating cavity 111, which can prevent the atomized matrix in the liquid storage space 1111 from leaking between the first sealing component 120 and the cavity wall of the first accommodating cavity 111. Furthermore, the injection hole 121 on the first sealing member 124 can replenish the atomized matrix in the liquid storage space 1111. In addition, by movably configuring the first valve member 130 within the atomizing air passage 112, the first valve member 130 can either move away from or into the first through hole 122, thereby enabling the opening and closing of the first through hole 122. Thus, before use, the liquid storage device 100 and the heating element 230 are separately configured; they only need to be installed together when the user uses the device. Therefore, the problem of atomized matrix leakage during transportation can be avoided. In addition, since the first valve component 130 has a simple structure, after it leaves the first through hole 122, the liquid storage space 1111 has no other structural obstruction to the position of the first through hole 122, and the atomizing matrix can flow smoothly into the first through hole 122.

[0031] Please refer to Figure 2 The liquid storage device 100 also includes an elastic member 140, an atomizing channel 112 having a support platform 1121, a first valve member 130 having a first support edge 131 at one end extending into the atomizing channel 112, and an elastic member 140 having one end abutting the support platform 1121 and the other end abutting the first support edge 131 to provide elastic potential energy for the first valve member 130 to be inserted into the first through hole 122 along the axial direction of the atomizing channel 112.

[0032] In this utility model, the elastic element 140 is a tension spring. When the end of the first valve element 130 near the first through hole 122 loses its abutment force, the elastic element 140 can push the first valve element 130 to block the first through hole 122, thereby realizing the automatic sealing of the first through hole 122 and effectively preventing the leakage of the atomized matrix.

[0033] Please refer to Figure 2 The first valve component 130 has a second abutment edge 132 at one end away from the first abutment edge 131. The second abutment edge 132 is used to abut against the atomizing tube 231 in the heating component 230 to push the first valve component 130 to move away from the first through hole 122.

[0034] In the liquid storage device 100 of this utility model, the movement of the first valve component 130 does not require the use of any other device to drive it. Instead, the heating component 230 of the electronic atomizing device is brought into contact with the second contact edge 132, thereby pushing the first valve component 130 to move in a direction away from the first through hole 122, thereby opening the first through hole 122.

[0035] Please refer to Figure 2 and Figure 5 The first sealing assembly 120 also includes a first sealing element 124 and a base 125. The first sealing element 124 is sleeved on the outer surface of the base 125 to seal the liquid storage space 1111. The injection hole 121 and the first through hole 122 are provided through the first sealing element 124 and the base 125.

[0036] In this application, the first sealing element 124 is made of silicone. By setting the first sealing element 124 on the base 125, on the one hand, the liquid storage space 1111 can be formed and sealed, and on the other hand, the atomizing matrix can be prevented from flowing out of the liquid storage space 1111.

[0037] Please refer to Figure 2 The first housing 110 has a limiting hole 114 on the side wall at the end away from the nozzle 113. The base 125 includes a limiting protrusion 1251, which is used to engage with the limiting hole 114 to fix the base 125 to the bottom of the first receiving cavity 111.

[0038] In this embodiment, the injection hole 121 includes two holes.

[0039] Please refer to Figure 2 The first valve component 130 has a first limiting groove 133 on the periphery of the portion of the atomizing air passage 112. A first sealing ring 150 is provided in the first limiting groove 133. The first sealing ring 150 is used to prevent the atomizing matrix from flowing from the atomizing air passage 112 to the nozzle 113.

[0040] This embodiment provides an electronic atomizing device 200. Please refer to [reference needed]. Figure 3-7 The electronic atomizing device 200 includes the liquid storage device 100 in Example 1, and also includes an atomizing device.

[0041] Please refer to Figure 5 The atomizing device includes a second housing 210, which is detachably connected to a first housing 110. A heating element 230 is fixedly installed inside the second housing 210. When the second housing 210 and the first housing 110 are in an assembled connection state, the heating element 230 abuts against the first valve component 130, the first valve component 130 disengages from the first through hole 122, and the heating element 230 is located inside the first through hole 122. The liquid storage space 1111 and the heating element 230 are connected through the first through hole 122. When the second housing 210 and the first housing 110 are in a disassembled state, the first valve component 130 is inserted into the first through hole 122 to block the first through hole 122.

[0042] This application places the liquid storage space 1111 on the first housing 110 and the heating element 230 on the second housing 210. Only when the first housing 110 and the second housing 210 are engaged does the heating element 230 press against the first valve 130, causing the first valve 130 to move away from the first through hole 122. This allows the atomized matrix to flow into the first through hole 122 and into the heating element 230 for atomization. When the first housing 110 and the second housing 210 are disassembled, the first valve 130, under the action of elastic restoring force, can enter the first through hole 122, thereby sealing the first through hole 122 and automatically preventing leakage of the atomized matrix. Thus, this embodiment separates the liquid storage device 100 and the heating element 230. The structure of the first valve 130 in the liquid storage device 100 is simple and does not obstruct the flow of the atomized matrix from the liquid storage space 1111 into the first through hole 122, facilitating smooth flow of the atomized matrix. In addition, the first sealing component 120 is set at the bottom of the liquid storage space 1111, which can prevent the atomizing matrix from leaking between the first sealing component 120 and the side wall of the first accommodating cavity 111. Furthermore, when the electronic atomizing device 200 is not in use, the first housing 110 and the second housing 210 can be disassembled. At this time, the first valve component 130 blocks the first through hole 122, which can also seal the liquid storage space 1111 and avoid the problem of atomizing matrix leakage caused by the first through hole 122 being open for a long time.

[0043] Please refer to Figure 2 or Figure 5 The bracket 220 is disposed within the second housing 210. The bracket 220 has a second through hole 221. The heating element 230 is fixedly inserted into the second through hole 221 and partially extends out of the second through hole 221. Please refer to [reference needed]. Figure 2 and Figure 5The second housing 210 has a second receiving cavity 211 and a second snap-fit ​​portion 212 for snapping with the first snap-fit ​​portion 115 of the first housing 110. The bracket 220 is disposed within the second receiving cavity 211.

[0044] Please refer to Figure 7 The heating element 230 includes an atomizing tube 231, a first liquid guiding element 232, a support element 233, and an atomizing core 234. The atomizing tube 231 is fixed to a second through hole 221 and partially extends out of the second through hole 221. The portion extending out of the second through hole 221 abuts against the second abutment edge of the first valve element 130. The atomizing tube 231 has a liquid guiding hole 2311. The support element 233 is disposed inside the atomizing tube 231. The first liquid guiding element 232 is disposed on the outer periphery of the support element 233. The atomizing core 234 is disposed inside the support element 233. The atomizing matrix can enter the first liquid guiding element 232 through the liquid guiding hole 2311 and be transported by the first liquid guiding element 232 to the atomizing core 234 for atomization.

[0045] In this embodiment, the support member 233 can stably support the first liquid guide member 232 and the atomizing core 234 inside the atomizing tube 231, preventing the first liquid guide member 232 and the atomizing core 234 from falling out of the atomizing tube 231.

[0046] Please refer to Figure 6 The support member 233 has a first opening 2331, which is used to allow the atomizing matrix to flow from the first liquid guide member 232 to the atomizing core 234.

[0047] Please refer to Figure 4 and Figure 7 A second limiting groove 2312 is provided on the periphery of the end of the atomizing tube 231 that abuts against the first valve component 130. A second sealing ring 240 is provided in the second limiting groove 2312 to prevent the atomizing matrix from entering the atomizing air passage 112 from the gap between the atomizing tube 231 and the first valve component 130.

[0048] Please refer to Figure 6-7 The outer side wall of the support member 233 has a first flange 2332, and the first liquid guiding member 232 abuts against the first flange 2332. The inner side wall of the support member 233 has a second flange 2333, and the atomizing core 234 abuts against the second flange 2333.

[0049] By providing a first flange 2332 and a second flange 2333 on the support member 233, the first liquid guide member 232 and the atomizing core 234 can be fixed to the support member 233 with a simple structure.

[0050] Please refer to Figure 7The heating element 230 also includes a fastener 235, which is disposed inside the support 233 and is used to fix the pins of the atomizing core 234. A fastening space is formed between the fastener 235 and the inner wall of the support 233, and the pins pass through the fastening space.

[0051] Please refer to Figure 2 and Figure 5 Part of the bracket 220 is disposed on the inner bottom of the second housing 210, and the bracket 220 located on the inner bottom of the second housing 210 has a mounting groove 222. The electronic atomizing device 200 also includes an airflow sensor 250, which is disposed in the mounting groove 222 and is used to sense the airflow in the second housing 210.

[0052] In this embodiment, as Figure 2 The airflow sensor 250 is a microphone. The electronic atomizing device 200 includes a circuit board 260, which is located at the bottom inside the second housing 210. The microphone is mounted on the circuit board 260 and extends into the mounting groove 222. The bottom of the second housing 210 has a gas inlet hole 2111 for connecting the second accommodating cavity 211 with the outside.

[0053] In some embodiments, the electronic atomizing device 200 further includes a power supply component 270, which is electrically connected to the heating component 230 and provides power to the heating component 230. The power supply component 270 and the heating component 230 can be a fixed electrical connection or a detachable electrical connection.

[0054] Please refer to Figure 4-5 The electronic atomizing device 200 also includes a power supply assembly 270.
