Description

Technical Field

[0001] This application relates to the technical field of aerosols, specifically to a liquid storage device and an atomizing apparatus. Background Technology

[0002] An atomizing device is a product that heats an atomizing substrate using an atomizing component, causing the substrate to generate an aerosol without combustion. The atomizing device includes an atomizing component with a storage chamber for holding the atomizing substrate. When the atomizing substrate needs to be replenished in the storage chamber, it is added through a reservoir bottle, which requires opening the bottle cap. To prevent accidental opening of the cap, the reservoir bottle typically has a child lock mechanism. In related technologies, the bottle neck has a threaded section for connecting the cap and implementing the child lock function, resulting in a longer bottle neck length, which is not conducive to reducing the overall length of the bottle. Utility Model Content

[0003] This application provides a liquid storage component and an atomizing device to solve the problem of long bottleneck length of liquid storage bottles.

[0004] In one embodiment, a liquid storage device is provided, comprising:

[0008] The outer cover includes a limiting part, which is disposed on the outer periphery of the inner cover. The limiting part is movably disposed along the axial direction of the liquid outlet hole so that when the limiting part leaves the locking part, the locking of the locking part and the connecting part is released.

[0009] In one embodiment, the inner wall of the outer cover is provided with a first threaded section, and the limiting part is connected to the end of the first threaded section near the liquid storage body; the outer periphery of the inner cover is provided with a second threaded section, and the snap-fit ​​part is connected to the end of the second threaded section near the liquid storage body; the first threaded section and the second threaded section cooperate to allow the limiting part to move axially along the liquid outlet hole.

[0010] In one embodiment, the outer cover has an extension section connected to the end of the first threaded section away from the liquid storage body, and the inner wall of the extension section near the end of the first threaded section has a limiting protrusion; the inner cover includes a support section connected to the end of the second threaded section away from the liquid storage body, and the outer periphery of the support section away from the second threaded section has a limiting flange; the extension section is sleeved on the support section, and the limiting protrusion corresponds to the limiting flange, for limiting the outer cover to detach from the inner cover along the axial direction, so that when the cover is removed, the inner cover and the outer cover detach together from the connecting part.

[0011] In one embodiment, an elastic reset member is provided between the connecting part and the inner cover. The elastic reset member is deformed by the inner cover to form a space in which the inner cover can move in the axial direction of the liquid outlet. The liquid storage body is provided with a boss, and the snap-fit ​​part is provided with a notch. The boss is used to insert into the notch through the axial movement of the inner cover in the liquid outlet to restrict the rotation of the inner cover.

[0012] In one embodiment, at least two elastic sheets are integrally provided on the end face of the connecting part, the elastic reset member is the elastic sheet, and the inner wall of the inner cover is provided with a stepped surface, the stepped surface corresponding to the end face of the connecting part, for deforming the elastic sheet by squeezing the elastic sheet through the stepped surface.

[0013] In one embodiment, the protrusion is provided with a first guiding slope, and the opening of the notch near one end of the liquid storage body is provided with a second guiding slope. The first guiding slope and the second guiding slope are applied to guide the protrusion to be inserted into the notch.

[0014] In one embodiment, the outer periphery of the connecting part is provided with an annular limiting groove, the snap-fit ​​part is detachably snapped into the limiting groove, the width of the limiting groove in the axial direction of the liquid outlet is a first distance, and the height of the space in the axial direction of the inner cover in the liquid outlet is a second distance, wherein the first distance is greater than the second distance.

[0015] In one embodiment, the snap-fit ​​portion includes at least two elastically deformable snap-fit ​​cantilever arms, each snap-fit ​​cantilever arm being distributed circumferentially along the inner cover. The inner side of the end of each snap-fit ​​cantilever arm is provided with a protrusion, and the outer periphery of the connecting portion is provided with an annular limiting groove. The snap-fit ​​portion forms a snap-fit ​​between the snap-fit ​​portion and the connecting portion by the elastic deformation of the snap-fit ​​cantilever arm causing the protrusion to engage in the limiting groove.

[0016] In one embodiment, the limiting portion is annular, and the annular limiting portion surrounds the outer periphery of each of the locking cantilevers, for releasing the locking by moving the limiting portion away from the locking portion along the axial direction of the liquid outlet hole.

The atomizing component includes a heating element and a storage cavity. The heating element is used to heat the atomizing matrix to generate an aerosol. The storage cavity is provided with a liquid inlet. The liquid storage component is used to remove the cover from the connecting part after the locking of the latching part and the connecting part is released, so as to connect the connecting part to the liquid inlet so that the liquid outlet communicates with the storage cavity.

[0018] According to the above embodiments of the liquid storage component and atomizing device, the liquid storage body is provided with a connecting portion, and the cover includes an inner cover and an outer cover. The inner cover is detachably snapped onto the connecting portion via a snap-fit ​​portion, and the outer cover includes a limiting portion located on the outer periphery of the inner cover. The limiting portion is movably disposed along the axial direction of the liquid outlet.

At this time, the limiting portion is located on the outer periphery of the inner cover, which can lock the snap-fit ​​between the snap-fit ​​portion and the connecting portion to prevent accidental opening of the liquid storage component. When it is necessary to remove the cover to provide the atomizing matrix to the atomizing component of the atomizing device through the liquid storage component, the limiting portion is moved along the axial direction of the liquid outlet to move away from the snap-fit ​​portion, thereby releasing the snap-fit ​​lock between the snap-fit ​​portion and the connecting portion. Then, the cover can be removed from the connecting portion by applying force. The connecting portion of the liquid storage component is the bottleneck, and there is no need to provide a threaded section on the bottleneck. This not only prevents accidental opening of the cover but also reduces the length of the bottleneck of the liquid storage component, which is beneficial to reducing the overall length of the liquid storage bottle.

[0033] The present application will now be described in further detail with reference to specific embodiments and accompanying drawings. 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. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0034] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0035] 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).

[0036] In related technologies, the atomizing device includes an atomizing component, which has a storage chamber for containing the atomizing matrix. When the atomizing matrix in the storage chamber is consumed and needs to be replenished, it must be added to the storage chamber through a liquid reservoir. Adding the matrix requires opening the cap of the liquid reservoir. To prevent accidental opening of the cap, the liquid reservoir is usually equipped with a child lock mechanism. Currently, the neck of the liquid reservoir has a threaded section and a connecting section. The threaded section is used to connect the cap and implement the child lock function, while the connecting section is used to connect the liquid reservoir to the atomizing component. The threaded section and connecting section on the neck result in a relatively long neck of the liquid reservoir, which is not conducive to reducing the overall length of the liquid reservoir.

[0037] In this application, a connecting part is provided on the liquid storage body, and the cover includes an inner cover and an outer cover. When the liquid storage component is not in use, the cover needs to be connected to the connecting part to cover the liquid outlet. At this time, the limiting part is located on the outer periphery of the inner cover, which can lock the engagement between the locking part and the connecting part to prevent the liquid storage component from being opened accidentally. When it is necessary to remove the cover to provide the atomizing matrix to the atomizing component of the atomizing device through the liquid storage component, the limiting part is moved axially along the liquid outlet to move the limiting part away from the locking part, thereby releasing the locking between the locking part and the connecting part. Then, the cover can be removed from the connecting part by pulling it. The connecting part of the liquid storage component is the bottleneck. There is no need to provide a threaded section on the bottleneck, which not only prevents the cover from being opened accidentally, but also reduces the length of the bottleneck of the liquid storage component, which is beneficial to reducing the overall length of the liquid storage bottle.

[0038] Please refer to Figures 1 to 9 This application provides a liquid storage device, which mainly includes a liquid storage body 3, a cover, and other functional components as needed, which are described in detail below.

[0039] In this embodiment, the liquid storage body 3 is provided with a connecting part 302 and a liquid storage chamber 301 for storing the atomizing matrix. The connecting part 302 is provided with a liquid outlet 303 communicating with the liquid storage chamber 301. The cover is connected to the connecting part 302 and covers the liquid outlet 303. The cover includes an outer cover 1 and an inner cover 2 provided inside the outer cover 1. The inner cover 2 is provided with a snap-fit ​​part 201, which is detachably snapped onto the connecting part 302 to detachably connect the cover to the connecting part 302. The outer cover 1 includes a limiting part 101, which is provided on the outer periphery of the inner cover 2. The limiting part 101 is movably provided along the axial direction of the liquid outlet 303 so that when the limiting part 101 leaves the snap-fit ​​part 201, the snap-fit ​​locking between the snap-fit ​​part 201 and the connecting part 302 is released.

[0040] It is understood that this application does not limit the shape of the liquid storage body 3, which can be a circular, square, or other shaped bottle structure. The liquid storage body 3 can be made of plastic, metal, or other materials. In this embodiment, the connecting part 302 and the liquid storage body 3 can be an integral structure. The connecting part 302 is used to connect with the liquid inlet of the atomizing component. In some embodiments, the connecting part 302 can be cylindrical. A cylindrical connecting part 302 is convenient to insert into the liquid inlet of the atomizing component and also facilitates the sealing between the connecting part 302 and the liquid inlet. In some application scenarios, the connecting part 302 can also be set to other shapes as needed. The cover in this embodiment includes an outer cover 1 and an inner cover 2. The outer cover 1 has a mounting cavity. For example, the outer cover 1 can be cylindrical, and the inner hole of the cylinder is the mounting cavity. The inner cover 2 is located in the mounting cavity. The inner cover 2 can be, but is not limited to, cylindrical. In this embodiment, the end of the outer cover 1 may be closed, covering the liquid outlet 303 of the connecting part 302, or the end of the inner cover 2 may be closed, covering the liquid outlet 303 of the connecting part 302, or both the ends of the outer cover 1 and the inner cover 2 may be closed. In some embodiments, a sealing structure, such as a sealing ring, may be provided between the inner cover 2 and the connecting part 302. In this embodiment, the inner cover 2 is detachably snapped onto the connecting part 302 by the snap-fit ​​part 201. The snap-fit ​​in this embodiment can connect the inner cover 2 to the connecting part 302, and at the same time, it can also release the snap-fit ​​part 201 from the connecting part 302 when pulled by an external force. In this embodiment, the limiting part 101 of the outer cover 1 is movably disposed along the axial direction of the liquid outlet 303, that is, the limiting part 101 can move towards the snap-fit ​​part 201 and away from the snap-fit ​​part 201. When moving towards the snap-fit ​​part 201 and moving to the limit position in that direction, such as Figure 1 As shown, the limiting part 101 locks the engagement between the latching part 201 and the connecting part 302. The limiting part 101 of the outer cover 1 is located outside the latching part 201 of the inner cover 2. By pressing the latching part 201, the latching part 201 cannot disengage from the connecting part 302. When it moves in a direction away from the latching part 201 and moves to the limit position in that direction, as... Figure 8As shown, the limiting part 101 of the outer cover 1 moves away from the snap-fit ​​part 201 of the inner cover 2, so that the snap-fit ​​part 201 is not pressed by the limiting part 101. The snap-fit ​​part 201 deforms outward, releasing the locking between the snap-fit ​​part 201 and the connecting part 302, so that the snap-fit ​​part 201 can be disengaged from the connecting part 302 under external force. In the liquid storage device provided in this embodiment, the liquid storage body 3 is provided with a connecting part 302 connected to the liquid inlet of the atomizing component. The cover includes an inner cover 2 and an outer cover 1. The inner cover 2 is detachably snapped onto the connecting part 302 by the snap-fit ​​part 201. The outer cover 1 includes a limiting part 101, which is provided on the outer periphery of the inner cover 2 and can move axially along the liquid outlet 303. When the liquid storage device is not in use, the cap must be attached to the connecting part 302 to cover the outlet 303. At this time, the limiting part 101 is located on the outer periphery of the inner cover 2, which can lock the engagement between the locking part 201 and the connecting part 302 to prevent the liquid storage device from being opened accidentally. When it is necessary to remove the cap and supply the atomizing matrix to the atomizing component of the atomizing device through the liquid storage device, the limiting part 101 is moved axially along the outlet 303 to move the limiting part 101 away from the locking part 201. The locking part 201 is no longer pressed by the limiting part 101, thereby releasing the locking engagement between the locking part 201 and the connecting part 302. Then, by pulling the cap, the entire cap consisting of the outer cover 1 and the inner cover 2 can be removed from the connecting part 302. The connecting part 302 of the liquid storage device is the bottleneck. There is no need to set a threaded section on the bottleneck, which not only prevents the cap from being opened accidentally, but also reduces the length of the bottleneck of the liquid storage device, which is beneficial to reducing the overall length of the liquid storage bottle.

[0041] In one embodiment, such as Figures 2-5 As shown, the inner wall of the outer cover 1 is provided with a first threaded section 103, and a limiting part 101 is connected to the end of the first threaded section 103 near the liquid storage body 3; the outer periphery of the inner cover 2 is provided with a second threaded section 207, and a snap-fit ​​part 201 is connected to the end of the second threaded section 207 near the liquid storage body 3; the threads of the first threaded section 103 and the second threaded section 207 are engaged to allow the limiting part 101 to move axially along the outlet hole 303. The cover body and the inner cover 2 are connected by threads. Tightening the outer cover 1 allows the outer cover 1 to move around the outer periphery of the inner cover 2. For example, when the outer cover 1 is tightened, the outer cover 1 can move in the direction close to the liquid storage body 3, and at the same time, the limiting part 101 on the outer cover 1 moves in the direction close to the snap-fit ​​part 201. When the outer cover 1 is loosened, the outer cover 1 can move in the direction away from the liquid storage body 3, and at the same time, the limiting part 101 on the outer cover 1 moves in the direction away from the snap-fit ​​part 201. To prevent the inner cover 2 from rotating when it is turned, the cover body can be pressed down while the outer cover 1 is turned so that the inner cover 2 is pressed tightly against the end of the connecting part 302. The rotation of the inner cover 2 is restricted by the friction between the end face of the inner cover 2 and the connecting part 302.

[0042] In one embodiment, the inner cover 2 can be engaged with the connecting part 302, and the outer cover 1 can be directly fixed to the inner cover 2. The limiting part 101 can be moved up and down on the outer cover 1. In normal state, the limiting part 101 abuts against the outer periphery of the engaging part 201 to lock the engagement between the engaging part 201 and the connecting part 302. By pushing the limiting part 101 upward to release the locking between the engaging part 201 and the connecting part 302, the locking of the engagement between the engaging part 201 and the connecting part 302 can be released. In some embodiments, the outer cover 1 and the limiting part 101 can be an integral structure. The outer cover 1 can be installed on the inner cover 2 in a way that allows it to move up and down. For example, the inner cover 2 is provided with a sliding groove that extends axially along the liquid outlet 303. The outer cover 1 is guided to move up and down by a protrusion in the sliding groove. Normally, the limiting part 101 abuts against the outer periphery of the locking part 201 to lock the locking part 201 and the connecting part 302. Pulling the outer cover 1 upward to make the limiting part 101 leave the locking part 201 can release the locking of the locking part 201 and the connecting part 302.

[0043] In one embodiment, when the cover body includes a first threaded section 103 and the inner cover 2 includes a second threaded section 207, as follows: Figures 2-5As shown, the outer cover 1 may have an extension section 102, which is connected to the end of the first threaded section 103 away from the liquid storage body 3. The inner wall of the extension section 102 near the end of the first threaded section 103 is provided with a limiting protrusion 104. The inner cover 2 includes a support section 205, which is connected to the end of the second threaded section 207 away from the liquid storage body 3. The outer periphery of the end of the support section 205 away from the second threaded section 207 is provided with a limiting flange 206. The extension section 102 is sleeved on the support section 205, and the limiting protrusion 104 corresponds to the limiting flange 206, which is used to restrict the outer cover 1 from detaching from the inner cover 2 axially, so that when the cover is removed, the inner cover 2 and the outer cover 1 detach together from the connecting part 302. When the inner cover 2 is assembled into the outer cover 1, the limiting flange 206 will press against the limiting protrusion 104 on the extension section and cross the limiting protrusion 104 to form a locking limit between the limiting flange 206 and the limiting protrusion 104, preventing the outer cover 1 and the inner cover 2 from separating from each other. For example, when the outer cover 1 is loosened, even if the threaded engagement between the first threaded section 103 and the second threaded section 207 is completely released, the outer cover 1 and the inner cover 2 will not separate because of the engagement between the limiting protrusion 104 and the limiting flange 206. In this embodiment, the limiting protrusion 104 is located at one end of the extension section 102 near the first threaded section 103, and the limiting flange 206 is located at one end of the support section 205 away from the second threaded section 207. After the extension section 102 is sleeved on the support section 205, the limiting protrusion 104 is located at one end of the fitting gap between the extension section 102 and the support section 205, and the limiting flange 206 is located at the other end of the fitting gap between the extension section 102 and the support section 205. That is, there is a certain distance between the limiting protrusion 104 and the limiting flange 206, which can make way for the movement of the limiting part 101. In some application scenarios, other structures can be used to limit the outer cover 1 and the inner cover 2 to prevent them from separating. Alternatively, no additional limiting structure can be set between the outer cover 1 and the inner cover 2 to prevent them from separating. For example, the lengths of the first threaded section 103 and the second threaded section 207 can be designed to be long enough so that after the outer cover 1 is loosened and the limiting part 101 is removed from the snap-fit ​​part 201, the first threaded section 103 and the second threaded section 207 still have mating threads. At this time, the outer cover 1 and the inner cover 2 are not easy to separate.

[0044] In one embodiment, such as Figure 2 , Figure 7As shown, an elastic reset member 4 is provided between the connecting part 302 and the inner cover 2. The elastic reset member 4 is used to be deformed by the inner cover 2 to form a space in which the inner cover 2 can move in the axial direction of the liquid outlet 303. The liquid storage body 3 is provided with a boss 304, and the snap-fit ​​part 201 is provided with a notch 203. The boss 304 is used to restrict the rotation of the inner cover 2 by moving the inner cover 2 in the axial direction of the liquid outlet 303 into the notch 203. Under normal conditions, the cover is held in the upper position by the elastic reset member 4. When the cover needs to be removed, the cover is pressed down, and the elastic reset member 4 deforms under the force. At this time, the outer cover 1 and the inner cover 2 move down to the lower position. Because the liquid storage body 3 is provided with a boss 304, the process of the cover approaching the liquid storage body 3 will cause the boss 304 to insert into the notch 203. After the boss 304 is inserted into the notch 203, the outer cover 1 is turned. At this time, the inner cover 2 will not rotate because it is restricted by the boss 304, so the outer cover 1 can be turned smoothly.

[0045] In one embodiment, at least two elastic sheets are integrally provided on the end face of the connecting part 302, the elastic reset member 4 is an elastic sheet, and the inner wall of the inner cover 2 is provided with a stepped surface 209, which corresponds to the end face of the connecting part 302 and is used to compress the elastic sheet by the stepped surface 209 to deform the elastic sheet. The integral fabrication of the elastic sheet on the end face of the connecting part 302 is simple and does not require additional assembly of the elastic reset member 4, which is beneficial to improving assembly efficiency. In this embodiment, the connecting part 302 can be made of plastic material with a limiting part, and the thickness of the plastic elastic sheet is sufficient to allow it to undergo elastic deformation. After the cover is removed, the outer cover 1 is no longer under pressure, and the elastic reset member 4 can restore its deformation. In some embodiments, the elastic reset member 4 can also be an elastic member integrally provided on the stepped surface 209 of the inner cover 2, or the elastic reset member 4 can also be a spring, which abuts between the stepped surface 209 of the inner cover 2 and the end face of the connecting part 302, or the elastic reset member 4 can also be silicone or a rubber ring, which can be compressed to undergo elastic deformation. In some application scenarios, the elastic reset member 4 may not be provided between the connecting part 302 and the inner cover 2. For example, the rotation of the inner cover 2 can be hindered by the friction between the end of the connecting part 302 and the inner cover 2 as described above.

[0046] In one embodiment, such as Figure 4As shown, the snap-fit ​​part 201 includes at least two elastically deformable snap-fit ​​cantilever arms 202, each snap-fit ​​cantilever arm 202 being distributed circumferentially along the inner cover 2. The inner side of the end of each snap-fit ​​cantilever arm 202 has a protrusion 204, and the outer periphery of the connecting part 302 has an annular limiting groove 305. The snap-fit ​​part 201 forms a snap-fit ​​connection between the snap-fit ​​part 201 and the connecting part 302 by the elastic deformation of the snap-fit ​​cantilever arm 202 causing the protrusion 204 to engage in the limiting groove 305. The snap-fit ​​cantilever arm 202 has a free end, which can undergo elastic deformation under force. During assembly, the cover is simply fastened onto the connecting part 302, making assembly simple and quick, and use easy. During the process of the cover being fastened onto the connecting part 302, the protrusion 204 of the snap-fit ​​cantilever 202 is compressed by the connecting part 302, causing the snap-fit ​​cantilever 202 to undergo an outward elastic deformation. The cover continues to be pushed until the protrusion 204 of the snap-fit ​​cantilever 202 is engaged in the limiting groove 305, at which point the snap-fit ​​cantilever 202 returns to its original shape. In this embodiment, two, three, four, or even more snap-fit ​​cantilever 202s can be provided, and each snap-fit ​​cantilever 202 can be evenly distributed along the circumference of the inner cover 2. In this embodiment, the snap-fit ​​cantilever 202 can be integrally formed during the manufacturing of the inner cover 2, but is not limited to this. Under normal conditions, the limiting part 101 is located on the outer periphery of the snap-fit ​​cantilever 202 and presses the snap-fit ​​cantilever 202 inward, thereby restricting the protrusion 204 of the snap-fit ​​cantilever 202 in the annular limiting groove 305 to form a locking of the snap-fit. Before removing the cover, the limiting part 101 is moved axially away from the snap-fit ​​cantilever 202, and the snap-fit ​​cantilever 202 is no longer compressed and recovers its deformation to reduce the depth of the protrusion 204 of the snap-fit ​​cantilever 202 in the limiting groove 305. At this time, the protrusion 204 of the snap-fit ​​cantilever 202 can be dislodged from the limiting groove 305 by the pulling force applied when removing the cover. After dislodging, the outer cover 1 and the inner cover 2 can be detached from the connecting part 302 together. In some embodiments, the snap-fit ​​part 201 can also be other shapes. For example, the inner cover 2 may have multiple windows in the circumferential direction, and each window may have an elastic arm extending from one side wall. Each elastic arm has a protrusion 204 at its free end. During assembly, the connecting part 302 presses the protrusion 204 of the elastic arm to make the elastic arm elastically move within the window until the protrusion 204 snaps into the annular limiting groove 305 of the connecting part 302, and the elastic arm then returns to its original shape.

[0047] In one embodiment, such as Figure 4 , Figure 7As shown, the boss 304 is provided with a first guide slope 306, and the notch 203 near the end of the liquid storage body 3 is provided with a second guide slope 208. The first guide slope 306 and the second guide slope 208 are applied to guide the boss 304 to insert into the notch 203. When the snap-fit ​​part 201 includes at least two elastically deformable snap-fit ​​cantilever 202, a gap is left between two adjacent snap-fit ​​cantilever 202 to form a notch 203. The end of the snap-fit ​​cantilever 202 is provided with a second guide slope 208. The first guide slope 306 and the second guide slope 208 are applied to guide the boss 304 to insert into the notch 203 between two adjacent snap-fit ​​cantilever 202. When the cover is pressed down, the inner cover 2 moves downward. When the first guide slope 306 contacts the second guide slope 208, the first guide slope 306 and the second guide slope 208 can slide against each other. This guides the inner cover 2 to rotate relative to the liquid storage body 3 to form a self-positioning, which is conducive to the smooth insertion of the boss 304 into the notch 203. The structure of the boss 304 inserting into the notch 203 is as follows: Figure 6 As shown. In some embodiments, other structures can be used to guide the boss 304 into the notch 203, or the guide ramp can be omitted. For example, the outer cover 1 can be made transparent, so that it can be directly observed whether the boss 304 is aligned with the notch 203, and it can be manually adjusted to align the boss 304 with the notch 203.

[0048] In one embodiment, such as Figure 2 , Figure 7 As shown, the outer periphery of the connecting part 302 is provided with an annular limiting groove 305. The snap-fit ​​part 201 is detachably snapped into the limiting groove 305. The width of the limiting groove 305 in the axial direction of the liquid outlet 303 is a first distance, and the height of the space in the axial direction of the inner cover 2 for movement in the liquid outlet 303 is a second distance. The first distance is greater than the second distance. This allows the protrusion 204 of the snap-fit ​​cantilever 202 to have space to move up and down within the limiting groove 305, preventing the inner cover 2 from being unable to move up and down due to the restriction of the protrusion 204 by the limiting groove 305.

[0049] In one embodiment, such as Figure 2 , Figure 5As shown, the limiting part 101 is annular, surrounding the outer periphery of each locking cantilever 202. It is used to release the locking mechanism by moving the limiting part 101 away from the locking part 201 along the axial direction of the liquid outlet 303, thus limiting the elastic deformation of the locking cantilever 202 to prevent locking. The annular limiting part 101 can be integrally formed with the outer cover 1. By fitting the annular limiting part 101 around the outer periphery of the locking cantilever 202, it restricts the outward elastic deformation of the locking cantilever 202, preventing the protrusion 204 of the locking cantilever 202 from disengaging from the limiting groove 305, thereby locking the locking between the locking part 201 and the connecting part 302. Conversely, when the annular limiting part 101 moves away from the locking cantilever 202, the locking cantilever 202 can undergo outward elastic deformation, thus releasing the locking between the locking part 201 and the connecting part 302. In some embodiments, the limiting part 101 may also be of other shapes, such as a plurality of plate-like structures arranged circumferentially along the inner cover 2, wherein the width of the plate-like structure is greater than the spacing between adjacent snap-fit ​​cantilever 202, and the spacing between adjacent plate-like structures is less than the width of the snap-fit ​​cantilever 202.

[0050] In the liquid storage device provided in the above embodiments, the liquid storage body 3 is provided with a connecting part 302 connected to the liquid inlet of the atomizing component, and the cover includes an inner cover 2 and an outer cover 1. The inner cover 2 is detachably snapped onto the connecting part 302 by a snap-fit ​​part 201. The outer cover 1 includes a limiting part 101, which is provided on the outer periphery of the inner cover 2 and can move axially along the liquid outlet 303. When not in use, the cap of the liquid storage device needs to be attached to the connecting part 302 to cover the outlet 303. At this time, the limiting part 101 is located on the outer periphery of the inner cover 2, which can lock the engagement between the locking part 201 and the connecting part 302 to prevent the liquid storage device from being opened accidentally. When it is necessary to remove the cap and supply the atomizing matrix to the atomizing component of the atomizing device through the liquid storage device, the limiting part 101 is moved axially along the outlet 303 so that the limiting part 101 is away from the locking part 201. The locking part 201 is not pressed by the limiting part 101, thereby releasing the locking engagement between the locking part 201 and the connecting part 302. Then, by pulling the cap, the entire cap consisting of the outer cover 1 and the inner cover 2 can be removed from the connecting part 302. The connecting part 302 of the liquid storage device is the bottleneck. There is no need to set a threaded section on the bottleneck, which not only prevents the cap from being opened accidentally, but also reduces the length of the bottleneck of the liquid storage device, which is beneficial to reducing the overall length of the liquid storage bottle.

[0051] Please refer to Figure 1 and Figure 9This application also provides an atomizing device, including: an atomizing component and a liquid storage component as described above. The atomizing component includes a heating element and a storage chamber. The heating element is used to heat the atomizing matrix to generate an aerosol. The storage chamber is provided with a liquid inlet. The liquid storage component is used to remove the cover from the connecting part 302 after the locking of the locking part 201 and the connecting part 302 is released, so as to connect the connecting part 302 to the liquid inlet so that the liquid outlet 303 communicates with the storage chamber.

[0052] It is understood that the liquid storage component in this embodiment is the same as that in the above embodiments, and will not be described again here. The atomizing component in this embodiment may include a heating element, a storage cavity, and other components, such as liquid storage cotton, which is disposed in the storage cavity to absorb the atomizing matrix. The atomizing matrix in this embodiment may be a medicinal liquid, e-liquid, or other liquid matrix that can be atomized. In one embodiment, when it is necessary to add the atomizing matrix into the storage cavity, the outer cover 1 can be pressed down so that the protrusion 304 on the liquid storage body 3 is inserted into the notch 203 of the inner cover 2 to restrict the rotation of the inner cover 2. Then, the outer cover 1 is twisted to rotate the outer cover 1 and drive the outer cover 1 to rise under the action of the first threaded section 103 and the second threaded section 207. At the same time, the limiting part 101 will also rise away from the snap-fit ​​part 201 of the inner cover 2. Then, the cover body is pulled with force, and the cover body composed of the outer cover 1 and the inner cover 2 can be removed from the connecting part 302. After the cover is removed, the liquid outlet of the connecting part 302 is opened. Then, the connecting part 302 is inserted into the liquid inlet of the atomizing component. After insertion, the atomizing matrix in the liquid storage component will be injected into the storage chamber of the atomizing component, thereby realizing the addition of the atomizing matrix.

[0053] In the atomizing device of the above embodiments, the liquid storage body 3 is provided with a connecting part 302 connected to the liquid inlet of the atomizing component. The cover includes an inner cover 2 and an outer cover 1. The inner cover 2 is detachably snapped onto the connecting part 302 by a snap-fit ​​part 201. The outer cover 1 includes a limiting part 101, which is provided on the outer periphery of the inner cover 2 and can move axially along the liquid outlet 303. When not in use, the cap of the liquid storage device needs to be attached to the connecting part 302 to cover the outlet 303. At this time, the limiting part 101 is located on the outer periphery of the inner cover 2, which can lock the engagement between the locking part 201 and the connecting part 302 to prevent the liquid storage device from being opened accidentally. When it is necessary to remove the cap and supply the atomizing matrix to the atomizing component of the atomizing device through the liquid storage device, the limiting part 101 is moved axially along the outlet 303 so that the limiting part 101 is away from the locking part 201. The locking part 201 is not pressed by the limiting part 101, thereby releasing the locking engagement between the locking part 201 and the connecting part 302. Then, by pulling the cap, the entire cap consisting of the outer cover 1 and the inner cover 2 can be removed from the connecting part 302. The connecting part 302 of the liquid storage device is the bottleneck. There is no need to set a threaded section on the bottleneck, which not only prevents the cap from being opened accidentally, but also reduces the length of the bottleneck of the liquid storage device, which is beneficial to reducing the overall length of the liquid storage bottle.
