Description

Technical Field

[0001] This application belongs to the field of atomizing equipment, specifically relating to a liquid storage device and an atomizing device. Background Technology

[0002] Typically, nebulizers include a liquid reservoir that stores the atomizing matrix. The atomizer extends within the reservoir, atomizing the matrix and allowing the user to directly inhale it. In related technologies, the reservoir has an inlet channel through which the atomizing matrix is ​​added from the outside, and then the channel is sealed. When sealing the inlet channel, a sealing post is usually inserted into it from the outside in. However, in these technologies, sealing the inlet channel with the sealing post can increase the internal pressure of the reservoir, potentially leading to leakage. Utility Model Content

[0003] The purpose of this application is to provide a liquid storage device and an atomizing device, which at least solves the problem of possible leakage of the liquid storage device when the liquid inlet channel is sealed by a sealing column.

[0004] In a first aspect, embodiments of this application provide a liquid storage device, which includes: a liquid storage chamber, a liquid inlet channel, and a sealing element;

[0005] The liquid inlet channel is connected to the liquid storage chamber, and the liquid inlet channel is used to inject the atomizing matrix into the liquid storage chamber, and the liquid storage chamber is used to store the atomizing matrix;

[0006] The sealing element is at least partially disposed in the liquid inlet channel. The sealing element includes a first segment and a second segment connected together. The outer diameter of the first segment is smaller than the outer diameter of the second segment. The outer diameter of the second segment is greater than or equal to the inner diameter of the liquid inlet channel. The second segment is located inside the liquid storage cavity, and the first segment is located outside the liquid storage cavity.

[0007] The first segment of the seal can drive the second segment to move between the liquid storage chamber and the liquid inlet channel, and the second segment can selectively block or open the liquid inlet channel.

[0008] In one embodiment, a lifting member is provided at the end of the first segment away from the second segment, and the lifting member is located outside the liquid inlet channel;

[0009] Along the axial direction of the liquid inlet channel, the projection of the lifting member at least partially overlaps with the projection of the liquid inlet channel, and a portion of the projection of the lifting member is located outside the projection of the liquid inlet channel.

[0010] In one embodiment, along the axial direction of the liquid inlet channel, a portion of the projection of the liquid inlet channel is located outside the projection of the lifting member.

[0011] In one embodiment, the lifting member is provided with a notch, and the projection of the notch is located inside the projection of the liquid inlet channel along the axial direction of the liquid inlet channel, and the notch avoids the liquid inlet channel.

[0012] In one embodiment, a blocking member is provided at the end of the second segment away from the first segment. The outer diameter of the blocking member is larger than the inner diameter of the second segment. The blocking member is used to prevent the second segment from detaching from the liquid inlet channel along the direction from the liquid storage cavity to the liquid inlet channel.

[0013] In one embodiment, a receiving groove is provided on the wall of the liquid storage chamber, and the receiving groove is located at the position where the liquid inlet channel communicates with the liquid storage chamber;

[0014] When the second segment moves to the liquid inlet channel, the blocking member is located in the receiving tank.

[0015] In one embodiment, a deformable boss is provided on the outer wall of the second segment;

[0016] When the second section is located in the liquid inlet channel, the boss abuts against the channel wall of the liquid inlet channel.

[0017] In one embodiment, the liquid storage device includes a liquid storage shell and a liquid storage cap;

[0018] The liquid storage shell has an opening and a receiving cavity, the liquid storage cap covers and seals the opening, and the receiving cavity and the liquid storage cap together form the liquid storage cavity;

[0019] The liquid storage cap is provided with a liquid inlet pipe, the inside of which is connected to the receiving cavity. The internal space of the liquid inlet pipe forms the liquid inlet channel, and the sealing element is disposed in the liquid inlet pipe.

[0020] In one embodiment, the liquid reservoir cap is provided with a through hole for atomizing an atomizer to be inserted, so that at least a portion of the atomizer extends into the liquid reservoir cavity.

[0021] Secondly, embodiments of this application provide an atomizing device, characterized in that the atomizing device includes a housing and a liquid storage device as described in any one of the first aspects above;

[0022] The liquid storage device is installed in the housing.

[0023] In this embodiment, since the seal is disposed in the liquid inlet channel, the seal includes a first segment and a second segment connected together. The outer diameter of the first segment is smaller than the outer diameter of the second segment, and the outer diameter of the second segment is greater than or equal to the inner diameter of the liquid inlet channel. The second segment is located inside the liquid storage cavity, and the first segment is located outside the liquid storage cavity. Therefore, the first segment can drive the second segment to move between the liquid storage cavity and the liquid inlet channel, so that the seal can seal the liquid inlet channel, or the seal can be released from the liquid inlet channel, thereby allowing the atomized matrix to be injected into the liquid storage cavity through the liquid inlet channel. Specifically, when it is necessary to inject the atomized matrix into the liquid storage device, the liquid storage device is in the liquid inlet state. At this time, the second segment of the seal is located in the liquid storage cavity, and part of the first segment extends into the liquid storage cavity, which can ensure the liquid inlet... There is a gap between the inner wall of the liquid channel and the first section, and this gap is not blocked by the second section. This gap is equivalent to forming a liquid flow space, so that the atomizing matrix can be injected into the liquid inlet channel. The atomizing matrix enters the liquid storage chamber through this gap, and the liquid inlet channel is not blocked. When the injection of atomizing matrix into the liquid storage chamber stops, force can be applied to the first section, that is, force is applied to the first section along the direction from the liquid storage chamber to the liquid inlet channel, so that the force direction of the first section is from the inside to the outside of the liquid storage chamber. Thus, the first section can drive the second section to move, so that at least part of the second section moves into the liquid inlet channel. The second section can then block the liquid inlet channel, which is equivalent to switching the liquid storage device from the liquid inlet state to the sealed state, preventing the atomizing matrix from leaking from the liquid inlet channel.

[0024] In this embodiment, by providing a sealing element comprising a first segment and a second segment, when it is necessary to seal the liquid inlet channel, force can be applied to the first segment, i.e., force is applied to the first segment from the inside of the liquid storage cavity to the outside of the liquid storage cavity, causing the second segment to move into the liquid inlet channel. This avoids the problem of increased pressure in the liquid storage cavity caused by the sealing element moving from the outside to the inside of the liquid storage cavity and sealing the liquid inlet channel. In other words, by applying force to the first segment to move the second segment into the liquid inlet channel to seal the liquid inlet channel, the pressure in the liquid storage cavity can be avoided while ensuring that the liquid inlet channel is sealed, thereby avoiding the problem of possible leakage of the liquid storage device.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] Before explaining the liquid storage device provided in the embodiments of this application, the application background of the liquid storage device provided in the embodiments of this application should be specifically explained: In related technologies, the liquid storage device has a liquid inlet channel. An atomizing matrix is ​​injected into the liquid storage device through the liquid inlet channel. Then, a sealing column is embedded into the liquid inlet channel along the direction from the outside of the liquid storage device to the inside of the liquid storage device. During the process of embedding the sealing column in the liquid inlet channel, the sealing column will compress the air inside the liquid storage channel, which will increase the pressure inside the liquid storage device and may cause the liquid storage device to leak. That is, there may be a problem of liquid leakage in the liquid storage device. If the size of the sealing column is reduced, the sealing effect will be worse and the liquid inlet channel will leak.

[0040] like Figures 1 to 8 As shown, the liquid storage device includes: a liquid storage chamber 10, a liquid inlet channel 20, and a sealing element 30.

[0041] The inlet channel 20 is connected to the storage chamber 10. The inlet channel 20 is used to inject the atomizing matrix into the storage chamber 10, and the storage chamber 10 is used to store the atomizing matrix. The sealing element 30 is at least partially disposed in the inlet channel 20. The sealing element 30 includes a first segment 31 and a second segment 32 connected together. The outer diameter of the first segment 31 is smaller than the outer diameter of the second segment 32. The outer diameter of the second segment 32 is greater than or equal to the inner diameter of the inlet channel 20. The second segment 32 is located inside the storage chamber 10, and the first segment 31 is located outside the storage chamber 10. The first segment 31 of the sealing element 30 can drive the second segment 32 to move between the storage chamber 10 and the inlet channel 20. The second segment 32 selectively blocks or opens the inlet channel 20.

[0042] The liquid storage device has a sealed state and a liquid inlet state. When the liquid storage device is in the liquid inlet state, the second section 32 is located in the liquid storage chamber 10, a portion of the first section 31 extends into the liquid storage chamber 10, and another portion of the first section 31 is located in the liquid inlet channel 20. When the first section 31 is subjected to force along the direction from the liquid storage chamber 10 to the liquid inlet channel 20, the first section 31 drives at least a portion of the second section 32 to move into the liquid inlet channel 20, and the second section 32 blocks the liquid inlet channel 20, so that the liquid storage device switches from the liquid inlet state to the sealed state.

[0043] In this embodiment, since the sealing element 30 is disposed in the liquid inlet channel 20, the sealing element 30 includes a first segment 31 and a second segment 32 connected together. The outer diameter of the first segment 31 is smaller than the outer diameter of the second segment 32, and the outer diameter of the second segment 32 is greater than or equal to the inner diameter of the liquid inlet channel 20. The second segment 32 is located inside the liquid storage cavity 10, and the first segment 31 is located outside the liquid storage cavity 10. Therefore, the first segment 31 can drive the second segment 32 to move between the liquid storage cavity 10 and the liquid inlet channel 20, so that the sealing element 30 seals the liquid inlet channel 20, or it can release the seal of the sealing element 30 on the liquid inlet channel 20, so that the atomizing matrix can be injected into the liquid storage cavity 10 through the liquid inlet channel 20. Specifically, when it is necessary to inject the atomizing matrix into the liquid storage device, the liquid storage device is in the liquid inlet state. At this time, the second segment 32 of the sealing element 30 is located in the liquid storage cavity 10, and part of the first segment 31 extends into the liquid storage cavity. 10 ensures that there is a gap between the inner wall of the liquid inlet channel 20 and the first section 31, and that this gap is not blocked by the second section 32. This gap is equivalent to forming a liquid flow space, allowing the atomizing matrix to be injected into the liquid inlet channel 20. The atomizing matrix enters the liquid storage chamber 10 through this gap, and the liquid inlet channel 20 is not blocked. When the injection of the atomizing matrix into the liquid storage chamber 10 stops, force can be applied to the first section 31, i.e., force is applied to the first section 31 in the direction from the liquid storage chamber 10 to the liquid inlet channel 20, so that the force direction of the first section 31 is from the inside to the outside of the liquid storage chamber 10. Thus, the first section 31 can drive the second section 32 to move, so that at least part of the second section 32 moves into the liquid inlet channel 20. The second section 32 can then block the liquid inlet channel 20, which is equivalent to switching the liquid storage device from the liquid inlet state to the sealed state, preventing the atomizing matrix from leaking from the liquid inlet channel 20. In this embodiment, by providing a sealing element 30 comprising a first segment 31 and a second segment 32, when it is necessary to seal the liquid inlet channel 20, force can be applied to the first segment 31, i.e., along the inside of the liquid storage cavity 10 towards the outside of the liquid storage cavity 10, causing the second segment 32 to move into the liquid inlet channel 20. This avoids the sealing element 30 moving along the direction from the outside to the inside of the liquid storage cavity 10 and sealing the liquid inlet channel 20, thus preventing the problem of increased pressure in the liquid storage cavity 10. In other words, by applying force to the first segment 31 to move the second segment 32 into the liquid inlet channel 20 to seal the liquid inlet channel 20, the pressure in the liquid storage cavity 10 can be avoided while ensuring that the liquid inlet channel 20 is sealed, thereby preventing the problem of possible leakage of the liquid storage device.

[0044] It should be noted that the sealing element 30 can be made of rubber, in which case both the first segment 31 and the second segment 32 are made of rubber. Of course, the sealing element 30 can also be made of other materials, such as silicone, in which case both the first segment 31 and the second segment 32 are supported by silicone. The specific material of the sealing element 30 is not limited in this embodiment.

[0045] In addition, in this embodiment of the application, when injecting the atomizing matrix into the liquid storage chamber 10, the inlet of the liquid inlet channel 20 faces upward. After the injection of the atomizing matrix into the liquid storage chamber 10 is completed, the sealing member 30 moves in the direction from bottom to top. That is, the first segment 31 of the sealing member 30 drives the second segment 32 to move from the inside of the liquid storage chamber 10 to the outside of the liquid storage chamber 10, that is, to move from the inside of the liquid storage chamber 10 to the inlet of the liquid inlet channel 20, so that the second segment 32 moves into the liquid inlet channel 20 and seals the liquid inlet channel 20.

[0046] Additionally, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, a lifting member 311 is provided at one end of the first segment 31 away from the second segment 32. The lifting member 311 is located outside the liquid inlet channel 20. Along the axial direction of the liquid inlet channel 20, the projection of the lifting member 311 at least partially overlaps with the projection of the liquid inlet channel 20, and part of the projection of the lifting member 311 is located outside the projection of the liquid inlet channel 20.

[0047] With this configuration, when force needs to be applied to the first segment 31 to move the second segment 32 into the liquid inlet channel 20, the operator can directly grasp the lifting member 311. This allows the operator to apply force to the first segment 31 via the lifting member 311, causing it to move from the inside to the outside of the liquid storage chamber 10. This, in turn, moves the second segment 32 into the liquid inlet channel 20, sealing it. Furthermore, the projection of the lifting member 311 at least partially overlaps with the projection of the liquid inlet channel 20, and a portion of the projection of the lifting member 311 lies outside the projection of the liquid inlet channel 20. This ensures that even when no force is applied to the lifting member 311, and the liquid storage device is placed vertically, the seal 30 and the lifting member 311 will not move into the liquid inlet channel 20 due to their own weight, thus ensuring easy gripping of the lifting member 311 by the operator. By setting up the lifting component 311, it is easy for the operator to apply force to the first section 31, so that the first section 31 drives the second section 32 to move into the liquid inlet channel 20, and the lifting component 311 can be prevented from falling into the liquid inlet channel 20.

[0048] It should be noted that the lifting component 311 can be integrally formed with the sealing component 30, that is, during the processing of the sealing component 30, the sealing component 30 and the lifting component 311 can be directly processed using an integral forming process. Of course, the lifting component 311 can also be connected to the first segment 31 through processes such as bonding or welding. In this respect, the embodiments of this application do not limit the scope of the application.

[0049] In some embodiments, along the axial direction of the liquid inlet channel 20, the projection of a portion of the liquid inlet channel 20 is located outside the projection of the lifting member 311. With this arrangement, when the liquid storage device is placed vertically, i.e., the liquid inlet channel 20 extends vertically, even if the lifting member 311 moves to the entrance of the liquid inlet channel 20 by its own gravity, the projection of a portion of the liquid inlet channel 20 is located outside the projection of the lifting member 311. This ensures that the lifting member 311 does not completely obstruct the liquid inlet channel 20, allowing the atomizing matrix to be injected into the liquid inlet channel 20 from the position where the lifting member 311 does not obstruct the liquid inlet channel 20, thus ensuring that the liquid storage device can be injected with the atomizing matrix.

[0050] It should be noted that the shape of the lifting component 311 can be set according to actual needs. For example, the shape of the lifting component 311 can be semi-circular, or for another example, the shape of the lifting component 311 can be square. The specific shape of the lifting component 311 is not limited in this embodiment.

[0051] In some embodiments, the lifting member 311 is provided with a notch. Along the axial direction of the liquid inlet channel 20, the projection of the notch is located inside the projection of the liquid inlet channel 20, and the notch avoids the liquid inlet channel 20. With this arrangement, when the liquid storage device is placed vertically, that is, when the liquid inlet channel 20 extends vertically, even if the lifting member 311 moves to the entrance of the liquid inlet channel 20 by its own gravity, the projection of the notch is located inside the projection of the liquid inlet channel 20, and the notch avoids the liquid inlet channel 20. This ensures that the lifting member 311 does not completely block the liquid inlet channel 20, and the atomizing matrix can be injected into the liquid inlet channel 20 through the notch on the lifting member 311, ensuring that the liquid storage device can be injected with the atomizing matrix.

[0052] It should be noted that the shape of the notch can be set according to actual needs. For example, the shape of the notch can be triangular, or even circular. The specific shape of the notch is not limited in this embodiment.

[0053] Additionally, in some embodiments, such as Figure 3 and Figure 4 As shown, a blocking member 321 is provided at the end of the second segment 32 away from the first segment 31. The outer diameter of the blocking member 321 is larger than the inner diameter of the second segment 32. The blocking member 321 is used to prevent the second segment 32 from detaching from the liquid inlet channel 20 along the direction from the liquid storage chamber 10 to the liquid inlet channel 20.

[0054] By providing a blocking member 321 at the end of the second segment 32 away from the first segment 31, and having an outer diameter larger than that of the second segment 32, the outer diameter of the blocking member 321 is made larger than that of the liquid inlet channel 20. Therefore, even if force is applied to the first segment 31, causing it to move the second segment 32 into the liquid inlet channel 20 (i.e., force is applied to the first segment 31 along the direction from the liquid storage chamber 10 to the liquid inlet channel 20), the second segment 32 will be moved into the liquid inlet channel 20 by the first segment 31. During the movement of the second segment 32, once the blocking member 321 contacts the wall of the liquid storage chamber 10, the blocking member 321 will be blocked by the wall of the liquid storage chamber 10. This effectively prevents the second segment 32 from being confined within the liquid inlet channel 20 by the blocking member 321, thus avoiding the problem of the first segment 31 moving the second segment 32 out of the liquid inlet channel 20 along the direction from the liquid storage chamber 10 to the liquid inlet channel 20 due to continuous force applied to the first segment 31. By setting the blocking element 321, it can be effectively ensured that the second section 32 will not be pulled to the outside of the liquid inlet channel 20 along the direction from the liquid storage chamber 10 to the liquid inlet channel 20, thus avoiding the problem that the liquid inlet channel 20 may not be able to be sealed.

[0055] It should be noted that the blocking component 321 can be integrally formed with the sealing component 30, that is, during the processing of the sealing component 30, the sealing component 30 and the blocking component 321 can be directly processed using an integral forming process. Of course, the blocking component 321 can also be connected to the first segment 31 through processes such as bonding or welding. In this respect, the embodiments of this application do not limit the scope of the application.

[0056] In addition, in this embodiment, the shape of the blocking member 321 can be circular. Of course, the shape of the blocking member 321 can also be other shapes, such as square. In this embodiment, it is only necessary to ensure that the blocking member 321 cannot enter the liquid inlet channel 20.

[0057] Additionally, in some embodiments, such as Figure 3 and Figure 7 As shown, a receiving groove 101 is provided on the cavity wall of the liquid storage chamber 10, and the receiving groove 101 is located at the position where the liquid inlet channel 20 communicates with the liquid storage chamber 10; when the second section 32 moves to the liquid inlet channel 20, the blocking member 321 is located in the receiving groove 101.

[0058] Because the storage chamber 10 has a receiving cavity on its wall, and the receiving groove 101 is located at the position where the inlet channel 20 communicates with the storage chamber 10, when force is applied to the first segment 31, causing the first segment 31 to move the second segment 32 into the inlet channel 20, the second segment 32 will also move the blocking member 321. Once the blocking member 321 moves into the receiving groove 101, it will be blocked by the groove wall of the receiving groove 101, preventing the second segment 32 from moving further. This ensures that the second segment 32 is located in the inlet channel 20, and the receiving groove 101 can accommodate the blocking member 321, preventing the blocking member 321 from occupying space in the storage chamber 10 and reducing the space in the storage chamber 10 that can accommodate the atomized matrix. In other words, by setting the receiving groove 101, the blocking member 321 can be moved into the receiving cavity, thereby increasing the space in the storage chamber 10 that can accommodate the atomized matrix.

[0059] It should be noted that the depth of the receiving groove 101 can be equal to the thickness of the blocking member 321. In this case, once the blocking member 321 moves into the receiving groove 101, the blocking member 321 can be flush with the cavity wall of the liquid storage chamber 10. In addition, in this embodiment, the shape of the receiving groove 101 can be the same as and adapted to the shape of the blocking member 321.

[0060] Additionally, in some embodiments, such as Figure 4 As shown, a deformable boss 322 is provided on the outer wall of the second section 32; when the second section 32 is located in the liquid inlet channel 20, the boss 322 abuts against the channel wall of the liquid inlet channel 20.

[0061] Because the outer wall of the second segment 32 is provided with a deformable protrusion 322, once a force is applied to the first segment 31, causing the first segment 31 to move the second segment 32 into the liquid inlet channel 20, the protrusion 322 on the second segment 32 will also move into the liquid inlet channel 20. The protrusion 322 is squeezed and abuts against the channel wall of the liquid inlet channel 20. The presence of the protrusion 322 can fix the second segment 32 in the liquid inlet channel 20, that is, ensure that the second segment 32 is not easy to move in the liquid inlet channel 20, thereby effectively avoiding the problem of the second segment 32 easily detaching from the liquid inlet channel 20.

[0062] It should be noted that the boss 322 can extend along the circumferential direction of the second segment 32, and the boss 322 surrounds the second segment 32. Of course, the boss 322 can also be other shapes, for example, the boss 322 can be triangular. In this case, there can be multiple bosses 322, and the multiple bosses 322 are distributed at intervals along the circumferential direction of the second segment 32. The specific shape of the boss 322 is not limited in this embodiment.

[0063] Furthermore, the number of protrusions 322 can be set according to actual needs. For example, the number of protrusions 322 can be 5, or even 6. The specific number of protrusions 322 is not limited in this embodiment. Therefore, in this application, larger protrusions 322 can be used to better seal the liquid inlet channel 20.

[0064] Additionally, in some embodiments, such as Figure 3 As shown, the liquid storage device includes a liquid storage shell 100 and a liquid storage cap 200. The liquid storage shell 100 has an opening and a receiving cavity. The liquid storage cap 200 closes and seals the opening. The receiving cavity and the liquid storage cap 200 together form a liquid storage cavity 10. A liquid inlet pipe 210 is provided on the liquid storage cap 200. The interior of the liquid inlet pipe 210 communicates with the receiving cavity, and the internal space of the liquid inlet pipe 210 forms a liquid inlet channel 20. A sealing element 30 is disposed in the liquid inlet pipe 210. With this arrangement, the liquid storage cap 200 and the receiving cavity of the liquid storage shell 100 can be closed to form the liquid storage cavity 10, and the closure and sealing of the opening by the liquid storage cap 200 ensures that the atomized matrix entering the liquid storage cavity 10 is not prone to leakage.

[0065] It should be noted that when the cavity wall of the liquid storage chamber 10 is provided with a receiving groove 101, the receiving groove 101 is provided on the liquid storage cover 200.

[0066] Additionally, in some embodiments, such as Figure 2 , Figure 3 and Figure 7 As shown, the liquid storage cap 200 is provided with a through hole 220 for passing through the atomizer 310 so that at least part of the atomizer 310 extends into the liquid storage chamber 10.

[0067] Because the liquid storage cap 200 has a through hole 220, when the liquid storage device is used in an atomizing device, the atomizer 310 of the atomizing device can extend into the liquid storage chamber 10 through the through hole 220, allowing the atomizer 310 to atomize the atomizing matrix in the liquid storage chamber 10. In other words, by providing the through hole 220 on the liquid storage cap 200, the atomizer 310 can be easily installed in the liquid storage chamber 10 to atomize the atomizing matrix in the liquid storage chamber 10.

[0068] In this embodiment, since the sealing element 30 is disposed in the liquid inlet channel 20, the sealing element 30 includes a first segment 31 and a second segment 32 connected together. The outer diameter of the first segment 31 is smaller than the outer diameter of the second segment 32, and the outer diameter of the second segment 32 is greater than or equal to the inner diameter of the liquid inlet channel 20. The second segment 32 is located inside the liquid storage cavity 10, and the first segment 31 is located outside the liquid storage cavity 10. Therefore, the first segment 31 can drive the second segment 32 to move between the liquid storage cavity 10 and the liquid inlet channel 20, so that the sealing element 30 seals the liquid inlet channel 20, or it can release the seal of the sealing element 30 on the liquid inlet channel 20, so that the atomizing matrix can be injected into the liquid storage cavity 10 through the liquid inlet channel 20. Specifically, when it is necessary to inject the atomizing matrix into the liquid storage device, the liquid storage device is in the liquid inlet state. At this time, the second segment 32 of the sealing element 30 is located in the liquid storage cavity 10, and part of the first segment 31 extends into the liquid storage cavity. 10 ensures that there is a gap between the inner wall of the liquid inlet channel 20 and the first section 31, and that this gap is not blocked by the second section 32. This gap is equivalent to forming a liquid flow space, allowing the atomizing matrix to be injected into the liquid inlet channel 20. The atomizing matrix enters the liquid storage chamber 10 through this gap, and the liquid inlet channel 20 is not blocked. When the injection of the atomizing matrix into the liquid storage chamber 10 stops, force can be applied to the first section 31, i.e., force is applied to the first section 31 in the direction from the liquid storage chamber 10 to the liquid inlet channel 20, so that the force direction of the first section 31 is from the inside to the outside of the liquid storage chamber 10. Thus, the first section 31 can drive the second section 32 to move, so that at least part of the second section 32 moves into the liquid inlet channel 20. The second section 32 can then block the liquid inlet channel 20, which is equivalent to switching the liquid storage device from the liquid inlet state to the sealed state, preventing the atomizing matrix from leaking from the liquid inlet channel 20. In this embodiment, by providing a sealing element 30 comprising a first segment 31 and a second segment 32, when it is necessary to seal the liquid inlet channel 20, force can be applied to the first segment 31, i.e., along the inside of the liquid storage cavity 10 towards the outside of the liquid storage cavity 10, causing the second segment 32 to move into the liquid inlet channel 20. This avoids the sealing element 30 moving along the direction from the outside to the inside of the liquid storage cavity 10 and sealing the liquid inlet channel 20, thus preventing the problem of increased pressure in the liquid storage cavity 10. In other words, by applying force to the first segment 31 to move the second segment 32 into the liquid inlet channel 20 to seal the liquid inlet channel 20, the pressure in the liquid storage cavity 10 can be avoided while ensuring that the liquid inlet channel 20 is sealed, thereby preventing the problem of possible leakage of the liquid storage device.
