Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to a liquid storage device, an atomizing device, and a vapor generating device. Background Technology

[0002] A vapor generator is an electronic device that can vaporize stored e-liquids, medicines, or other atomizing liquids into vapor through electric heating. A vapor generator typically includes an atomizer and a power supply unit. The atomizer generally includes a storage chamber for storing the atomizing liquid and an atomizing core for absorbing the atomizing liquid and vaporizing it into vapor. The power supply unit is used to supply power to the atomizing core.

[0003] In related technologies, the storage chamber of atomizers is typically designed to be relatively small (usually 2ml), preventing the addition of a large amount of e-liquid at the factory, thus resulting in a short lifespan for the atomizer. To extend the atomizer's lifespan, related technologies can equip the atomizer with a larger, replaceable reservoir. Once the e-liquid stored in the atomizer is depleted by the coil, the user can replenish it from the reservoir, allowing the atomizer to continue operating. However, these vapor generators equipped with reservoirs generally suffer from the following problems:

[0004] When the atomizing fluid in the reservoir is depleted from replenishing the atomizer, it is usually necessary to remove the reservoir and replace it with a new one to ensure the atomizer can continue to be used for a long time. However, during the process of removing the reservoir from the atomizer, the atomizing fluid in the storage chamber of the atomizer is prone to leaking from the connection point between the atomizer and the reservoir, resulting in leakage in the atomizing device and causing a poor user experience. Utility Model Content

[0005] The main objective of this application is to provide a liquid storage device, an atomizing device, and a vapor generation device, aiming to solve the technical problem that leakage easily occurs when the liquid storage device is replaced in the related art.

[0006] To achieve the above objectives, in a first aspect, this application provides a vapor-generating device, which includes:

[0007] An atomizing body includes an atomizer, which includes a first housing, an atomizing core, and a sealing cap made of an elastic sealing material. The first housing has an airflow channel, an installation channel spaced apart from the airflow channel, and a first storage chamber for storing atomized liquid. The atomizing core is installed on the airflow path of the airflow channel and communicates with the first storage chamber. The sealing cap is sealed within the installation channel, and a first liquid passage hole is provided on its circumferential sidewall. The sealing cap is configured to slide relative to the first housing along the axial direction of the installation channel, and the sliding range of the sealing cap is limited between a first position and a second position.

[0008] A liquid reservoir includes a second housing, a second storage chamber for storing atomized liquid inside the second housing, and a liquid outlet nozzle. The liquid outlet nozzle has a second liquid passage hole on its circumferential side wall for discharging the atomized liquid in the second storage chamber. The liquid outlet nozzle is detachably and sealedly inserted into the inside of the sealing cover, and the second liquid passage hole is connected to the first liquid passage hole.

[0009] Specifically, when the liquid outlet causes the sealing cap to slide from the first position to the second position, the second liquid passage is connected to the first storage cavity; when the liquid outlet causes the sealing cap to slide from the second position to the first position, the first liquid passage is blocked by the inner wall of the installation channel, thus isolating the second liquid passage from the first storage cavity; when the liquid outlet is pulled out from the inside of the sealing cap, the sealing cap remains in the first position.

[0010] In some embodiments, the inner wall of the installation channel is provided with a first limiting protrusion for restricting the sealing cover to the first position, wherein when the sealing cover is in the first position, the first limiting protrusion is in contact with the end face of the sealing cover facing the first limiting protrusion.

[0011] In some embodiments, the outer wall of the second housing is provided with a liquid outlet pipe, and the end of the liquid outlet pipe opposite to the second housing is provided with a liquid outlet nozzle. The outer wall of the liquid outlet pipe along its circumference is provided with a limiting groove. The inner wall of the sealing cover near the end of the first limiting protrusion is provided with a second limiting protrusion. The second limiting protrusion is inserted into the limiting groove, and the end face of the second limiting protrusion opposite to the first limiting protrusion is in contact with the groove wall surface of the limiting groove facing the second housing.

[0012] In some embodiments, when the sealing cap is in the first position, the contact area between the first limiting protrusion and the end face of the sealing cap facing the first limiting protrusion is greater than the contact area between the end face of the second limiting protrusion facing away from the first limiting protrusion and the groove wall surface of the limiting groove facing the second housing.

[0013] In some embodiments, both the first limiting protrusion and the second limiting protrusion are annular protrusions, and the limiting groove is an annular groove.

[0014] In some embodiments, the frictional force between the outer wall of the sealing cap along its circumference and the inner wall of the mounting channel is less than the frictional force between the inner wall of the sealing cap along its circumference and the outer wall of the dispensing nozzle.

[0015] In some embodiments, the sealing cap has at least one sealing protrusion protruding on its outer wall along its circumference, the at least one sealing protrusion being spaced apart from the first liquid passage and in contact with the inner wall of the installation channel.

[0016] In some embodiments, the first housing includes an outer shell, a base, a connector, and an air duct having at least a portion of the airflow channel. The base is sealed to the bottom of the outer shell. The air duct is located inside the outer shell, with one end sealed to the top of the outer shell and the other end sealed to the base. The outer shell, the base, and the air duct together define the first storage cavity. A liquid inlet is provided on the side wall of the air duct, communicating with the first storage cavity. The atomizing core is installed inside the air duct and covers the liquid inlet. The connector includes a hollow pipe portion. The installation channel is formed through the pipe, which penetrates the base along the thickness direction and forms a sealed connection with the base. A third liquid passage hole is provided on the side wall of the pipe, which is located in and communicates with the first storage cavity. Along the height direction of the outer shell, there is a minimum vertical distance between the wall of the third liquid passage hole and the bottom wall of the first storage cavity, which is greater than or equal to 1 mm. When the sealing cover is in the second position, the first liquid passage hole and the third liquid passage hole are connected, which makes the second liquid passage hole connected with the first storage cavity.

[0017] In some embodiments, when the sealing cap is in the second position, the end face of the sealing cap facing away from the second housing contacts the inner wall of the first storage cavity.

[0018] In some embodiments, the frictional force between the inner wall of the sealing cap along its circumference and the outer wall of the dispensing nozzle is F1; the frictional force between the outer wall of the sealing cap along its circumference and the inner wall of the mounting channel is F2 when the sealing cap is in the second position and in the transition position between the second position and the first position; and the frictional force between the outer wall of the sealing cap along its circumference and the inner wall of the mounting channel is F3 when the sealing cap is in the first position, where F2 < F1 < F3.

[0019] In some embodiments, the atomizing body further includes a power supply assembly, which includes a third housing, a battery, and a control circuit board. One end of the third housing along its height direction is connected to the first housing. The battery and the control circuit board are both installed inside the third housing. The control circuit board is electrically connected to the battery and the atomizing core, respectively. The mounting channel extends along the height direction of the first housing, and one end of the mounting channel is located on the bottom wall of the first housing. The third housing has a through hole for the liquid outlet nozzle to pass through and a receiving cavity for the second housing to be installed. The through hole is provided corresponding to the mounting channel, and the receiving cavity is located below the through hole. At least a portion of the second housing is detachably installed in the receiving cavity.

[0020] In some embodiments, the elastic sealing material includes any one of silicone, rubber, and silicone rubber.

[0021] In some embodiments, the volume of the second storage cavity is 2.5 to 5.5 times the volume of the first storage cavity.

[0022] In some embodiments, the end face of the liquid outlet facing away from the second housing is closed.

[0023] In some embodiments, the interior of the second housing further includes a first cavity spaced apart from the second storage cavity. The first cavity contains a column extending along the height direction of the second housing. The column has a first liquid guiding channel extending axially along the column, and the inlet end of the first liquid guiding channel is connected to the second storage cavity. The outer wall of the second housing has a protruding outlet pipe with an outlet nozzle at one end facing away from the second housing. The outlet pipe has a second liquid guiding channel inside. The liquid reservoir further includes a pump assembly, which includes:

[0024] A piston cylinder is slidably installed in the first cavity along the height direction of the second housing. The piston cylinder has a second cavity extending along the axial direction of the piston cylinder. One end of the piston cylinder is sealed and sleeved on the outer wall of the column. The second cavity is connected to the liquid outlet end of the first liquid guiding channel and the liquid inlet end of the second liquid guiding channel, respectively.

[0025] A first valve body is disposed within the first liquid guiding channel, and the first valve body is used to open and close the liquid inlet end of the first liquid guiding channel;

[0026] The second valve body is disposed inside the liquid outlet, and the second valve body is used to open and close the liquid outlet end of the second liquid guiding channel;

[0027] A pusher, one end of which is fixedly connected to the piston cylinder and the other end exposed in the second housing, is configured to drive the piston cylinder to slide along the direction close to the inlet end of the first liquid guiding channel when subjected to external force, so that the first valve body closes the inlet end of the first liquid guiding channel and the second valve body opens the outlet end of the second liquid guiding channel; and

[0028] An elastic element, one end of which is fixed relative to the piston cylinder and the other end of which is fixed relative to the column, is configured to drive the piston cylinder to reset when the external force applied to the push member is removed, so that the first valve body opens the inlet end of the first liquid guiding channel and the second valve body closes the outlet end of the second liquid guiding channel.

[0029] Secondly, this application also provides a liquid storage device for detachably combining with the atomizing body in the vapor generating device described in any of the above embodiments. The liquid storage device is the liquid reservoir in the vapor generating device described in any of the above embodiments.

[0030] Thirdly, this application also provides an atomizing device for detachable combination with the liquid reservoir in the vapor generating device described in any of the above embodiments, wherein the atomizing device is the atomizing body in the vapor generating device described in any of the above embodiments.

[0031] Compared with the prior art, this application has at least the following beneficial effects:

[0032] In the technical solution of this application, on the one hand, the first housing of the atomizer is provided with an installation channel and a sealing cover that is sealed and fitted in the installation channel. The sealing cover has a first liquid passage hole on its circumferential side wall. The sealing cover is configured to slide along the axial direction of the installation channel and the sliding range of the sealing cover is limited between a first position and a second position. On the other hand, the second housing of the liquid reservoir is provided with a liquid outlet. The liquid outlet has a second liquid passage hole on its circumferential side wall for discharging the atomized liquid in the liquid reservoir. The liquid outlet is detachably and sealedly inserted into the inside of the sealing cover and the second liquid passage hole is connected to the first liquid passage hole. With this configuration, when the atomizing fluid in the first storage chamber of the atomizer is depleted by the atomizing coil and needs to be replenished, the reservoir can be pushed, causing the nozzle to slide the sealing cap from a first position to a second position. This allows the second liquid outlet of the nozzle to connect with the first storage chamber of the atomizer through the first liquid outlet of the sealing cap, enabling the atomizing fluid in the second storage chamber of the reservoir to be introduced into the first storage chamber of the atomizer for replenishment through the second and first liquid outlets. After replenishment, the reservoir can be pulled, causing the nozzle to slide the sealing cap from a second position to a first position. This allows the first liquid outlet of the sealing cap to be blocked by the inner wall of the mounting channel, thus isolating the second liquid outlet of the nozzle from the first storage chamber of the atomizer and preventing the atomizing fluid in the first storage chamber from flowing back into the second storage chamber. When the atomizing liquid in the reservoir is depleted and a new reservoir needs to be replaced, the reservoir can be pulled to remove the nozzle from the inside of the sealing cap. During this process, the sealing cap remains in a position that isolates the second liquid passage from the first storage chamber, preventing the atomizing liquid in the first storage chamber from leaking to the outside through the first liquid passage and the installation channel. This effectively prevents leakage from the vapor generator during the removal of the reservoir from the atomizer. After removing the depleted reservoir from the atomizer, insert the nozzle of the new reservoir into the installation channel and connect it to the inside of the sealing cap. This allows the atomizer to be replenished with atomizing liquid from the new reservoir, enabling it to continue to be used for an extended period. Attached Figure Description

[0065] Please refer to Figure 1-11 One embodiment of this application provides a vapor generation device, which includes an atomizing body and a liquid reservoir 2, wherein:

[0066] The atomizing body includes an atomizer 1, which includes a first housing 11, an atomizing core 12, and a sealing cap 13 made of elastic sealing material. The first housing 11 has an airflow channel 102, an installation channel 103 spaced apart from the airflow channel 102, and a first storage chamber 101 for storing atomizing liquid. The atomizing core 12 is installed inside the first housing 11 and communicates with the first storage chamber 101, allowing the atomizing core 12 to draw atomizing liquid from the first storage chamber 101 for heating and atomization to produce vapor that can be inhaled by the user. Furthermore, the atomizing core 12 is located on the airflow path of the airflow channel 102 so that the vapor produced by the atomizing core 12 can be formed in the airflow channel. The suction airflow in the flow channel 102 is carried away and discharged to the outside for the user to inhale; in addition, in order to facilitate the user to inhale, the top of the first housing 11 is connected to a suction nozzle 14 (the material of the suction nozzle 14 can be plastic) that communicates with the airflow channel 102. When the user bites the suction nozzle 14 to inhale, a suction airflow can be formed in the airflow channel 102; the sealing cover 13 is sealed and fitted in the installation channel 103, and the sealing cover 13 has a first liquid passage hole 131 on its circumferential side wall. The sealing cover 13 is configured to slide relative to the first housing 11 along the axial direction of the installation channel 103, and the sliding range of the sealing cover 13 is limited between the first position and the second position.

[0067] The liquid reservoir 2 includes a second housing 21, which has a second storage chamber 201 for storing atomized liquid. The second housing 21 is provided with a liquid outlet 221. The liquid outlet 221 has a second liquid passage hole 2210 on its circumferential sidewall for discharging the atomized liquid in the second storage chamber 201. The liquid outlet 221 is detachably and sealedly inserted into the interior of the sealing cover 13 (specifically, the connection between the liquid outlet 221 and the sealing cover 13 is a plug-in connection. After the liquid outlet 221 is inserted into the interior of the sealing cover 13, it forms a sealing fit with the sealing cover 13. In the illustration, after the liquid outlet 221 is inserted into the interior of the sealing cover 13, the circumferential outer wall and the top surface of the liquid outlet 221 are in contact with the inner wall of the sealing cover 13). The second liquid passage hole 2210 of the liquid outlet 221 is connected to the first liquid passage hole 131 of the sealing cover 13.

[0068] Please refer to the reference. Figure 2-5 Or refer to Figure 8-10 When the dispensing nozzle 221 drives the sealing cap 13 to slide from the first position to the second position, the second liquid passage 2210 connects with the first storage chamber 101, at which time the atomized liquid in the second storage chamber 201 can be replenished into the first storage chamber 101. For example, as shown... Figure 4-5As shown, in some application scenarios where the second liquid passage 2210 is connected to the second storage chamber 201, when the sealing cover 13 slides to the second position, the entire vapor generator can be inverted (at this time, the nozzle 14 faces downwards), so that the atomizing liquid in the second storage chamber 201 can be introduced into the first storage chamber 101 of the atomizer 1 for replenishment through the second liquid passage 2210 of the liquid outlet 221 and the first liquid passage 131 of the sealing cover 13 in sequence under the action of gravity.

[0069] Please refer to the reference. Figure 2-5 Or refer to Figure 8-10 When the dispensing nozzle 221 drives the sealing cap 13 to slide from the second position to the first position, the first liquid passage 131 is blocked by the inner wall of the mounting channel 103, thus isolating the second liquid passage 2210 from the first storage cavity 101. This prevents the atomized liquid in the first storage cavity 101 from leaking to the outside through the first liquid passage 131 and the mounting channel 103 when the dispensing nozzle 221 is subsequently pulled out from the inside of the sealing cap 13. It also prevents the atomized liquid in the first storage cavity 101 from flowing back into the second storage cavity 201 through the second liquid passage 2210 of the dispensing nozzle 221 in some application scenarios. For example, as... Figure 4 and Figure 2 As shown, in some application scenarios where the second liquid passage 2210 is connected to the second storage cavity 201, after the atomizing liquid is replenished, the liquid outlet 221 can be pulled to slide the sealing cover 13 to the first position, and then the entire vapor generator can be straightened (at this time the suction nozzle 14 is facing upward) so that the user can use the vapor generator for suction later.

[0070] like Figure 2 and 6 As shown, when the nozzle 221 is pulled out from the inside of the sealing cap 13, the sealing cap 13 remains in a first position isolated from the second liquid passage 2210 and the first storage cavity 101, thereby preventing the atomized liquid in the first storage cavity 101 from leaking to the outside through the first liquid passage 131 and the installation channel 103. That is, the atomized liquid in the first storage cavity 101 cannot leak to the outside through the first liquid passage 131, nor can it leak to the outside through the gap between the circumferential outer wall of the sealing cap 13 and the inner wall of the installation channel 103.

[0071] In this embodiment, it should be noted that, in specific implementation, the above-mentioned elastic sealing material can be a silicone, rubber, silicone rubber or other elastic sealing material. That is, the sealing cover 13 can be made of a silicone, rubber, silicone rubber or other elastic sealing material, as long as it can achieve the sealing between the outer circumferential wall of the sealing cover 13 and the inner wall of the installation channel 103, the sealing between the inner circumferential wall of the sealing cover 13 and the outer circumferential wall of the liquid outlet 221, and the plug-in connection between the liquid outlet 221 and the sealing cover 13. This embodiment does not impose specific restrictions on the specific material of the sealing cover 13.

[0072] In this embodiment, it should also be noted that, in specific implementation, the sealing fit between the sealing cap 13 and the mounting channel 103 can be a transition fit or an interference fit, as long as it can achieve a seal between the circumferential outer wall of the sealing cap 13 and the inner wall of the mounting channel 103, and allow the sealing cap 13 to slide along the axial direction of the mounting channel 103 when subjected to external force. This embodiment does not impose specific limitations on this. For example, in some optional embodiments, please refer to... Figure 3 , Figure 5 , Figure 10 , Figure 18 and Figure 21 The sealing cover 13 has at least one sealing protrusion 133 protruding from its circumferential outer wall, surrounding the sealing cover 13. The at least one sealing protrusion 133 is spaced apart from the first liquid passage 131 and contacts the inner wall of the mounting channel 103. This arrangement not only ensures a reliable seal between the circumferential outer wall of the sealing cover 13 and the inner wall of the mounting channel 103, but also allows the sealing cover 13 to slide smoothly along the axial direction of the mounting channel 103 when subjected to external force. In specific implementations, the sealing protrusion 133 can be a sealing ring (in which case the sealing protrusion 133 is fitted onto the circumferential outer wall of the sealing cover 13) or it can be part of the sealing cover 13 itself (in which case the sealing protrusion 133 is integrally formed with the circumferential outer wall of the sealing cover 13). Any form that meets the usage requirements is acceptable. This embodiment does not impose specific limitations on the specific structural form of the sealing protrusion 133. The illustration is as follows: Figure 10 and 21 As shown, the sealing protrusion 133 is part of the sealing cover 13 itself. Multiple sealing protrusions 133 are provided, spaced apart axially along the sealing cover 13, and the first liquid passage hole 131 is located between at least two sealing protrusions 133. It can be understood that when the sealing protrusion 133 is a sealing ring, the sealing fit between the sealing cover 13 and the mounting channel 103 is an indirect fit; while when the sealing protrusion 133 is part of the sealing cover 13 itself, the sealing fit between the sealing cover 13 and the mounting channel 103 is a direct fit.

[0073] In this embodiment, based on the above structural design, when the atomizing liquid in the first storage chamber 101 of the atomizer 1 is consumed by the atomizing core 12 and needs to be replenished, the second housing 21 of the reservoir 2 can be pushed, causing the nozzle 221 to drive the sealing cap 13 to slide from the first position to the second position, so that the second liquid passage 2210 of the nozzle 221 can be connected to the first storage chamber 101 of the atomizer 1 through the first liquid passage 131 of the sealing cap 13, thereby allowing the liquid in the second storage chamber 201 of the reservoir 2 to be replenished. The atomizing liquid can be introduced into the first storage chamber 101 of the atomizer 1 through the second liquid passage 2210 and the first liquid passage 131 for replenishment; after replenishment, the second housing 21 of the liquid reservoir 2 can be pulled, causing the nozzle 221 to drive the sealing cap 13 to slide from the second position to the first position, so that the first liquid passage 131 of the sealing cap 13 can be blocked by the inner wall of the installation channel 103, thereby isolating the second liquid passage 2210 of the nozzle 221 from the first storage chamber 101 of the atomizer 1, preventing the first liquid from being replenished. The atomizing liquid in storage chamber 101 flows back to the second storage chamber 201. When the atomizing liquid in the reservoir 2 is depleted and a new reservoir 2 needs to be replaced, the second housing 21 of the reservoir 2 can be pulled to remove the nozzle 221 from the inside of the sealing cover 13. Since the sealing cover 13 remains in a first position, isolating the second liquid passage 2210 from the first storage chamber 101, the atomizing liquid in the first storage chamber 101 cannot pass through the first liquid passage 2210 during the removal of the nozzle 221. The liquid outlet 131 and the installation channel 103 prevent leakage to the outside, thus effectively preventing leakage of the vapor generation device during the process of removing the liquid reservoir 2 from the atomizer 1. After the liquid reservoir 2, which has been depleted of atomizing liquid, is removed from the atomizer 1, the outlet 221 of the new liquid reservoir 2 is inserted into the installation channel 103 and plugged into the inside of the sealing cap 13. This allows the atomizer 1 to be replenished with atomizing liquid through the new liquid reservoir 2, enabling the atomizer 1 to continue to be used for a long time.

[0074] Furthermore, in some optional embodiments of this application, in order to enable the dispensing nozzle 221 to smoothly drive the sealing cap 13 from the second position to the first position, and to ensure that the sealing cap 13 remains in the first position when the dispensing nozzle 221 is pulled out from the inside of the sealing cap 13, in specific implementation, the frictional force (assumed to be F1) between the inner wall of the sealing cap 13 along its own circumference and the outer wall of the dispensing nozzle 221 can be set to be greater than the frictional force (assumed to be F2) between the outer wall of the sealing cap 13 along its own circumference and the inner wall of the mounting channel 103 when the sealing cap 13 is in the second position and in the transition position between the second position and the first position, and less than the frictional force (assumed to be F3) between the outer wall of the sealing cap 13 along its own circumference and the inner wall of the mounting channel 103 when the sealing cap 13 is in the first position, that is, F2 < F1 < F3.

[0075] In this embodiment, it is understood that the size design of F1 can be achieved by changing the material of the sealing cap 13 and the dispensing nozzle 221, adjusting the contact area between the inner wall of the sealing cap 13 along its circumference and the outer wall of the dispensing nozzle 221, adjusting the surface roughness of the inner wall of the sealing cap 13 along its circumference, and adjusting the surface roughness of the outer wall of the dispensing nozzle 221 along its circumference. Similarly, the size design of F2 and F3 can be achieved by changing the material of the inner wall of the sealing cap 13 and the mounting channel 103, adjusting the contact area between the sealing cap 13 and the inner wall of the mounting channel 103, adjusting the surface roughness of the part of the sealing cap 13 that contacts the mounting channel 103, and adjusting the surface roughness of the inner wall of the mounting channel 103. As long as F2 < F1 < F3, this embodiment does not impose specific restrictions on the specific size design of F1, F2, and F3. It can also be understood here that F2 changes when the sealing cover 13 is in the transition position between the second position and the first position. Specifically, as the sealing cover 13 slides from the second position to the first position, F2 will gradually increase due to factors such as the surface roughness of the inner wall of the installation channel 103 gradually increasing.

[0076] In this embodiment, it should be noted that, assuming that when the sealing cover 13 is in the first position, the sealing cover 13 occupies the first space area of ​​the installation channel 103, and when the sealing cover 13 is in the second position, the sealing cover 13 occupies the second space area of ​​the installation channel 103, then when the sealing cover 13 is in the above-mentioned transition position, a part of the sealing cover 13 will be located in the first space area and a part of the sealing cover 13 will be located in the second space area.

[0077] Alternatively, please refer to Figure 2-3 , Figure 6 as well as Figure 9-10In some exemplary embodiments of this application, the inner wall of the mounting channel 103 is provided with a first limiting protrusion 11311 for restricting the sealing cap 13 to a first position. When the sealing cap 13 is in the first position, the first limiting protrusion 11311 contacts the end face of the sealing cap 13 facing the first limiting protrusion 11311 (i.e., the lower end face of the sealing cap 13). With this configuration, when the sealing cap 13 is in the first position and the liquid outlet 221 is pulled, the first limiting protrusion 11311 can reliably block the sealing cap 13, allowing the liquid outlet 221 to smoothly detach from the inside of the sealing cap 13. At the same time, the sealing cap 13 can be stably held in the first position without being pulled away from the mounting channel 103 by the liquid outlet 221, thus preventing the atomized liquid in the atomizer 1 from leaking to the outside through the mounting channel 103. It should be noted that, in specific implementation, the first limiting protrusion 11311 can be set as an annular shape, that is, the first limiting protrusion 11311 is an annular protrusion. This setting can increase the contact area between the first limiting protrusion 11311 and the sealing cover 13, thereby improving the blocking effect of the first limiting protrusion 11311 on the sealing cover 13, so that the sealing cover 13 can be more stably kept in the first position and will not be taken away from the installation channel 103 by the liquid outlet 221.

[0078] Further, please refer to Figure 2 , Figure 4 as well as Figure 8-9 In some optional embodiments of this application, the frictional force between the outer wall of the sealing cap 13 along its circumference and the inner wall of the mounting channel 103 is less than the frictional force between the inner wall of the sealing cap 13 along its circumference and the outer wall of the dispensing nozzle 221. This arrangement allows the dispensing nozzle 221 to stably pull the sealing cap 13 from the second position to the first position, thereby reducing the risk of leakage caused by the sealing cap 13 accidentally detaching from its interior before reaching the first position during the sliding process.

[0079] Further, please refer to Figure 3 , Figure 10 and Figure 21In some optional embodiments of this application, the outer wall of the second housing 21 is provided with a liquid outlet pipe 22 (exemplarily, the liquid outlet pipe 22 protrudes upward from the top surface of the second housing 21, and the material of the liquid outlet pipe 22 can be plastic). The end of the liquid outlet pipe 22 away from the second housing 21 is provided with a liquid outlet nozzle 221. The outer wall of the liquid outlet pipe 22 along its own circumference is provided with a limiting groove 2201. The inner wall of the sealing cover 13 near the end of the first limiting protrusion 11311 is provided with a second limiting protrusion 132. The second limiting protrusion 132 is inserted into the limiting groove 2201, and the end face of the second limiting protrusion 132 away from the first limiting protrusion 11311 (i.e., the upper surface of the second limiting protrusion 132) is in contact with the groove wall surface of the limiting groove 2201 facing the second housing 21 (i.e., the top wall surface of the limiting groove 2201).

[0080] In this embodiment, based on the above structural design, when the dispensing nozzle 221 is pulled, the top wall surface of the limiting groove 2201 can abut against the upper surface of the second limiting protrusion 132, allowing the dispensing nozzle 221 to more easily drive the sealing cap 13 from the second position to the first position. This helps reduce the risk of leakage caused by the sealing cap 13 accidentally detaching from its interior before reaching the first position during the process of driving the sealing cap 13 from the second position to the first position. It should be noted that, in specific implementations, the second limiting protrusion 132 can be set as an annular protrusion, and the limiting groove 2201 can be set as an annular groove. This configuration increases the contact area between the second limiting protrusion 132 and the dispensing nozzle 221, thereby enabling the dispensing nozzle 221 to more reliably drive the sealing cap 13 from the second position to the first position.

[0081] Further, please refer to Figure 3 and Figure 10 In some optional embodiments of this application, when the sealing cover 13 is in the first position, the contact area between the first limiting protrusion 11311 and the end face of the sealing cover 13 facing the first limiting protrusion 11311 is greater than the contact area between the end face of the second limiting protrusion 132 facing away from the first limiting protrusion 11311 and the groove wall surface of the limiting groove 2201 facing the second housing 21. This configuration ensures that when the sealing cap 13 is in the first position and the dispensing nozzle 221 is pulled, the blocking effect of the first limiting protrusion 11311 on the sealing cap 13 is greater than the blocking effect of the second limiting protrusion 132 on the dispensing nozzle 221. This effectively ensures that the sealing cap 13 can be stably maintained in the first position, while allowing the dispensing nozzle 221 to squeeze the second limiting protrusion 132 to undergo elastic deformation and smoothly detach from the inside of the sealing cap 13. This effectively prevents the sealing cap 13 from being pulled away from the installation channel 103 by the dispensing nozzle 221, thus preventing the atomized liquid in the atomizer 1 from leaking to the outside through the installation channel 103.

[0082] Further, please refer to Figure 3 , Figure 6 , Figure 10 and Figure 21 In some optional embodiments of this application, the sealing cap 13 has a guide hole 130 at one end near the first limiting protrusion 11311. The guide hole 130 is located between the end face of the sealing cap 13 facing the first limiting protrusion 11311 and the second limiting protrusion 132. The inner wall of the guide hole 130 is integrally connected with the inner wall of the annular second limiting protrusion 132. The inner diameter of the guide hole 130 gradually decreases along the direction near the second limiting protrusion 132 (i.e., the inner diameter of the guide hole 130 gradually decreases from bottom to top), and the minimum inner diameter of the guide hole 130 is equal to the inner diameter of the second limiting protrusion 132, while the maximum inner diameter of the guide hole 130 is greater than the outer diameter of the dispensing nozzle 221. With this configuration, during the replacement of the liquid reservoir 2, when the dispensing nozzle 221 is inserted into the interior of the sealing cap 13, the guide hole 130 can play a certain guiding role, thereby making it easier for the dispensing nozzle 221 to be inserted into the interior of the sealing cap 13.

[0083] Further, please refer to Figure 5 and Figure 8 In some optional embodiments of this application, when the sealing cover 13 is in the second position, the end face of the sealing cover 13 facing away from the second housing 21 (i.e., the upper end face of the sealing cover 13) is in contact with the inner wall of the first storage cavity 101 (specifically, the inner wall of the first storage cavity 101 facing the upper port of the mounting channel 103). With this configuration, firstly, when it is necessary to replenish the atomizing liquid in the second storage chamber 201 to the first storage chamber 101 and the sealing cap 13 needs to be slid to the second position, the inner wall of the first storage chamber 101 acts as a barrier, allowing the sealing cap 13 to accurately reach the second position where the second liquid outlet 2210 connects to the first storage chamber 101. That is, when the user can clearly perceive that the dispensing nozzle 221 cannot be pushed to continue moving upward, it indicates that the sealing cap 13 has reached the second position. Secondly, during the replacement of the liquid reservoir 2, when the dispensing nozzle 221 is inserted into the sealing cap 13, there may be a situation where "the dispensing nozzle 221 is not fully inserted into the sealing cap 13 before the sealing cap 13 is slid upward." The barrier of the inner wall of the first storage chamber 101 ensures that the dispensing nozzle 221 can be fully inserted into the sealing cap 13 instantly when the sealing cap 13 reaches the second position, thus avoiding liquid leakage due to the dispensing nozzle 221 not being fully inserted into the sealing cap 13 and affecting subsequent replenishment of atomizing liquid.

[0084] Further, please refer to Figure 2-5In some optional embodiments of this application, the end face of the dispensing nozzle 221 facing away from the second housing 21 (i.e., the upper end face of the dispensing nozzle 221) is closed. This configuration prevents the atomized liquid in the dispensing nozzle 221 from contacting and adhering to the inner wall of the sealing cap 13 during the process of replenishing the atomized liquid from the second storage chamber 201 into the first storage chamber 101. Consequently, when the dispensing nozzle 221 is subsequently removed from the sealing cap 13, the risk of leakage (such as the atomized liquid adhering to the inner wall of the sealing cap 13 dripping under gravity) due to excessive atomized liquid adhering to the inner wall of the sealing cap 13 is avoided.

[0085] Further, please refer to Figure 4-6 In some optional embodiments of this application, the installation channel 103 has a first channel 1031 and a second channel 1032 that are interconnected along its own axial direction. The first limiting protrusion 11311 is located between the first channel 1031 and the second channel 1032. The sealing cover 13 is sealed and fitted in the first channel 1031. The inner diameter of the second channel 1032 is gradually reduced in the direction close to the first limiting protrusion 11311 (i.e., the inner diameter of the second channel 1032 gradually decreases from bottom to top). The liquid outlet pipe 22 has a pipe section 222. One end of the pipe section 222 is connected to the second housing 21 and the other end is connected to the liquid outlet 221. The outer diameter of the pipe section 222 is gradually reduced in the direction away from the second housing 21 (i.e., the outer diameter of the pipe section 222 gradually decreases from bottom to top). When the sealing cover 13 is in the second position, at least a portion of the pipe section 222 is fitted in the second channel 1032. This design serves two purposes. First, the second channel 1032, whose inner diameter gradually decreases from bottom to top and matches the outer diameter of the pipe section 222, can act as a guide, allowing the user to push and pull the outlet pipe 22 more smoothly along the axial direction of the installation channel 103. This enables the outlet nozzle 221 to drive the sealing cap 13 to slide between the first and second positions more smoothly, without causing any jamming. Second, in some applications where the outlet pipe 22 is made of plastic through injection molding, designing the outer diameter of the pipe section 222 to gradually decrease from bottom to top is equivalent to giving the outlet pipe 22 a certain draft angle. This allows the outlet pipe 22 to be more easily removed from the mold during injection molding, preventing damage.

[0086] Further, please refer to Figure 7-10 and Figure 14-21 In some optional embodiments of this application, the interior of the second housing 21 is further provided with a first cavity 202 that is spaced apart from the second storage cavity 201. The first cavity 202 contains a cavity along the height direction of the second housing 21 (i.e., Figure 7-9The reservoir 2 includes a column 211 extending vertically, with a first liquid guiding channel 2110 extending axially along the column 211. The inlet end of the first liquid guiding channel 2110 is connected to the second storage chamber 201. The outlet pipe 22 has a second liquid guiding channel 2202. The reservoir 2 also includes a pump assembly 23, which includes a piston cylinder 233, a first valve body 231, a second valve body 232, a pusher 234, and an elastic element 235, wherein:

[0087] The piston cylinder 233 is slidably installed in the first cavity 202 along the height direction of the second housing 21. The piston cylinder 233 has a second cavity 2330 extending along the axial direction of the piston cylinder 233. One end of the piston cylinder 233 is sealed and sleeved on the outer wall of the column 211 (in specific implementation, the lower end of the piston cylinder 233 can be made of sealing materials such as silicone, rubber, and silicone rubber). The second cavity 2330 is connected to the liquid outlet end of the first liquid guiding channel 2110 (i.e., the upper port of the column 211) and the liquid inlet end of the second liquid guiding channel 2202 (i.e., the lower port of the liquid outlet pipe 22).

[0088] The first valve body 231 is disposed within the first liquid guiding channel 2110. The first valve body 231 is configured to open and close the liquid inlet end (i.e., the lower port of the column 211) of the first liquid guiding channel 2110. For example, the first valve body 231 is a sphere, and the first valve body 231 can function as a one-way valve. It can be understood that when the first valve body 231 opens the liquid inlet end of the first liquid guiding channel 2110, the first liquid guiding channel 2110 is connected to the second storage cavity 201, and when the first valve body 231 closes the liquid inlet end of the first liquid guiding channel 2110, the first liquid guiding channel 2110 is isolated from the second storage cavity 201.

[0089] The second valve body 232 is disposed inside the liquid outlet 221. The second valve body 232 is configured to open and close the liquid outlet end of the second liquid guiding channel 2202 (i.e., the end of the second liquid guiding channel 2202 near the inner cavity of the liquid outlet 221). For example, the second valve body 232 is a sphere and can function as a one-way valve. It can be understood that when the second valve body 232 opens the liquid outlet end of the second liquid guiding channel 2202, the liquid outlet end of the second liquid guiding channel 2202 is connected to the second liquid passage 2210, thereby connecting the second liquid guiding channel 2202 to the first storage cavity 101. When the second valve body 232 closes the liquid outlet end of the second liquid guiding channel 2202, the liquid outlet end of the second liquid guiding channel 2202 is isolated from the second liquid passage 2210, thereby isolating the second liquid guiding channel 2202 from the first storage cavity 101.

[0090] One end of the pusher 234 is fixedly connected to the piston cylinder 233, and the other end is exposed outside the second housing 21. The pusher 234 is configured to drive the piston cylinder 233 to slide along the direction close to the liquid inlet end of the first liquid channel 2110 when subjected to external force, so that the first valve body 231 closes the liquid inlet end of the first liquid channel 2110 and the second valve body 232 opens the liquid outlet end of the second liquid channel 2202, so as to prevent the atomized liquid in the space connected to the second liquid channel 2202 and the first liquid channel 2110 from flowing back into the second storage chamber 201 and to pump the atomized liquid stored in the space connected to the second liquid channel 2202 and the first liquid channel 2110 into the first storage chamber 101 for replenishment.

[0091] One end of the elastic element 235 is fixed relative to the piston cylinder 233, and the other end is fixed relative to the column 211. The elastic element 235 is configured to drive the piston cylinder 233 to reset when the external force applied to the pusher 234 is removed, so that the first valve body 231 opens the inlet end of the first liquid guiding channel 2110 and the second valve body 232 closes the outlet end of the second liquid guiding channel 2202, so as to "draw" the atomized liquid in the second storage chamber 201 into the space connected to the second liquid guiding channel 2202 and the first liquid guiding channel 2110 for storage. In specific implementation, the elastic element 235 can be a spring, sheet, rubber band, or other element with good elastic properties, as long as it can meet the usage requirements. This embodiment does not impose specific limitations on this. For example, the elastic element 235 is a spring, and one end of the elastic element 235 abuts against the inner wall of the piston cylinder 233, and the other end abuts against the inner wall of the column 211.

[0092] In this embodiment, based on the above structural design, it is convenient for the user to replenish the atomized liquid in the second storage chamber 201 into the first storage chamber 101. Specifically, the user can replenish the atomized liquid in the second storage chamber 201 into the first storage chamber 101 by repeatedly pushing the pusher 234. When the pusher 234 is in its initial position, the first valve body 231 is in a state where the inlet end of the first liquid channel 2110 is closed, and the second valve body 232 is in a state where the outlet end of the second liquid channel 2202 is closed. When the user pushes the pusher 234 downwards with their finger, the pusher 234 pushes the piston cylinder 233 downwards. During the downward movement of the piston cylinder 233, the elastic element 235 is gradually compressed, and at the same time, the volume of the second chamber 2330 of the piston cylinder 233 decreases, thereby... This causes an increase in air pressure within the space connecting the second liquid guiding channel 2202 and the first liquid guiding channel 2110. Under this increased air pressure, the second valve body 232 is lifted, connecting the outlet end of the second liquid guiding channel 2202 with the second liquid passage 2210 of the outlet nozzle 221. This continues until the air pressure within the space connecting the second liquid guiding channel 2202 and the first liquid guiding channel 2110 reaches equilibrium with the air pressure within the first storage chamber 101. Then, the second valve body 232 falls back to close under its own weight. The state of the liquid outlet of the liquid guiding channel 2202; when the user removes the pushing force applied to the pusher 234, under the action of the elastic restoring force of the elastic element 235, the piston cylinder 233 drives the pusher 234 to move upward together. During the upward movement of the piston cylinder 233, the spatial volume of the second cavity 2330 of the piston cylinder 233 will increase, thereby forming a negative pressure in the space connecting the second liquid guiding channel 2202 and the first liquid guiding channel 2110. Under the action of this negative pressure, the first valve body 231 is "sucked" The first liquid guide channel 2110 is connected to the second storage chamber 201, allowing the atomized liquid in the second storage chamber 201 to be "drawn" into the space where the second liquid guide channel 2202 and the first liquid guide channel 2110 are connected. When the air pressure in the space where the second liquid guide channel 2202 and the first liquid guide channel 2110 are connected reaches equilibrium with the air pressure in the second storage chamber 201, the first valve body 231 falls back to the state of closing the liquid inlet end of the first liquid guide channel 2110 under its own gravity.Thus, by repeatedly pushing the pusher 234, the space connecting the second liquid channel 2202 and the first liquid channel 2110 can store more and more atomized liquid (specifically, each time the pusher 234 completes one round trip, a certain amount of atomized liquid is "drawn" from the second storage cavity 201 into the space connecting the second liquid channel 2202 and the first liquid channel 2110), until the amount of atomized liquid in the space connecting the second liquid channel 2202 and the first liquid channel 2110 reaches a certain level and pushes the pusher 234 downwards. When the atomized liquid in the space connecting the second liquid channel 2202 and the first liquid channel 2110 is pushed up, the second valve body 232 can be sprayed into the first storage chamber 101 through the second liquid passage 2210 of the liquid outlet 221 and the first liquid passage 131 of the sealing cap 13 for replenishment. In this way, each time the pusher 234 is pushed down, a certain amount of atomized liquid can be sprayed into the first storage chamber 101 for replenishment until the atomized liquid in the second storage chamber 201 and the space connecting the second liquid channel 2202 and the first liquid channel 2110 is consumed.

[0093] In this embodiment, by adding the pump assembly 23, firstly, the user does not need to tilt or invert the entire vapor generator when replenishing the atomizing liquid, thereby improving the convenience of user operation; secondly, since the second valve body 232 automatically falls back to the state of closing the liquid outlet of the second liquid channel 2202 after each injection of a certain amount of atomizing liquid into the first storage chamber 101, the atomizing liquid in the first storage chamber 101 cannot flow back into the second storage chamber 201 without the need to drive the sealing cover 13 from the second position to the first position. That is, even if the sealing cover 13 is kept in the second position, the atomizing liquid in the first storage chamber 101 will not flow back. The liquid flows into the second storage chamber 201, which makes it easier for the first storage chamber 101 to be filled with atomizing liquid and improves the user's operating experience. Thirdly, since the sealing cap 13 can always be kept in the second position before the atomizing liquid in the reservoir 2 is consumed and a new reservoir 2 needs to be replaced, and when the sealing cap 13 is in the second position, the upper end face of the sealing cap 13 is in contact with the inner wall of the first storage chamber 101. Therefore, the atomizing liquid in the first storage chamber 101 cannot flow into the space above the sealing cap 13 in the installation channel 103, thereby avoiding the reduction of the atomizing liquid utilization rate due to the atomizing liquid remaining in the space above the sealing cap 13 in the installation channel 103.

[0094] Further, please refer to Figure 1-2 , Figure 4 , Figure 6-9 and Figure 11In some optional embodiments of this application, to facilitate subsequent inhalation by the user, the atomizing body further includes a power supply component 3. The power supply component 3 includes a third housing 31, a battery 32, and a control circuit board 33. The third housing 31 extends along its own height direction (i.e., 1-2). Figure 4 , Figure 6-9 and Figure 11 One end of the mounting channel 103 (in the vertical direction) is connected to the first housing 11. The battery 32 and the control circuit board 33 are both installed inside the third housing 31. The control circuit board 33 is electrically connected to the battery 32 and the atomizing core 12 respectively. The control circuit board 33 can control the battery 32 to supply power to the atomizing core 12, so that the atomizing core 12 can be powered on to perform atomization. The mounting channel 103 is along the height direction of the first housing 11 (i.e., 1-2, ...). Figure 4 , Figure 6-9 and Figure 11 The second housing 21 is provided with a through hole 313 through which the liquid nozzle 221 passes and a receiving cavity 310 for mounting the second housing 21. The through hole 313 is provided corresponding to the mounting channel 103, and the receiving cavity 310 is located below the through hole 313. At least a portion of the second housing 21 is detachably installed in the receiving cavity 310. With this configuration, the power assembly 3 can not only provide power to the atomizing core 12, but also accommodate the liquid reservoir 2, making the connection between the liquid reservoir 2 and the atomizer 1 more stable and easier for the user to hold the entire electronic atomizing device, thus facilitating subsequent vaping by the user.

[0095] In this embodiment, it should be noted that, in specific implementation, the first shell 11 can be a one-piece structure or a split structure assembled from different shell structures. Similarly, the second shell 21 can be a one-piece structure or a split structure assembled from different shell structures. Similarly, the third shell 31 can be a one-piece structure or a split structure assembled from different shell structures. The specific structural form can be determined according to the actual use needs. This embodiment does not impose specific restrictions on the specific structural forms of the first shell 11, the second shell 21, and the third shell 31.

[0096] In this embodiment, it should also be noted that, in specific implementation, the connection between the first housing 11 and the third housing 31 can be a detachable connection (such as a magnetic connection, threaded connection, snap-fit ​​connection, etc.) or a non-detachable fixed connection (such as an integral connection), which can be determined according to actual usage needs. This embodiment does not impose specific limitations on this. As for the detachable connection between the second housing 21 and the third housing 31, it can specifically be a magnetic connection (in this case, the inner wall of the receiving cavity 310 and the outer wall of the second housing 21 are both provided with magnets that can attract each other), a snap-fit ​​connection, etc., and this embodiment also does not impose specific limitations on this.

[0097] Exemplary, in some optional embodiments, the connection between the first housing 11 and the third housing 31 is a detachable snap-fit ​​connection, specifically, as shown in... Figure 7-8 and Figure 11-13 As shown, the top sidewall of the third housing 31 is provided with a first latching hole 315. The third housing 31 has a receiving groove 314 located above the through hole 313. The first housing 11 has a first buckle 1110 adapted to the first latching hole 315 on its circumferential sidewall. The bottom of the first housing 11 is inserted into the receiving groove 314 of the third housing 31, and the first buckle 1110 is fastened in the first latching hole 315, thereby realizing a detachable connection between the first housing 11 and the third housing 31. When it is necessary to remove the atomizer 1 from the third housing 31 of the power assembly 3, the atomizer 1 can be pulled out upwards with force.

[0098] Exemplarily, in some optional embodiments, the detachable connection between the second housing 21 and the third housing 31 is a snap-fit ​​connection, specifically, as shown in... Figure 4 , Figure 6 , Figure 8 , Figure 11 , Figure 14 and Figure 16 As shown, the bottom of the third housing 31 is provided with a first opening 311 that directly communicates with the receiving cavity 310, and the third housing 31 has a second opening 312 that directly communicates with the receiving cavity 310 on its circumferential sidewall. The second opening 312 is directly connected to the first opening 311 (illustratively, as shown). Figure 11As shown, the second opening 312 is in the shape of an inverted "U" (i.e., the lower end of the second opening 312 is open). At least one second buckle 212 protrudes from the outer wall of the second housing 21 along its circumference. At least one second locking hole 316, adapted to the second buckle 212, is provided on the inner wall of the receiving cavity 310. When the sealing cover 13 is in the first position and / or the second position, at least one second buckle 212 engages with at least one second locking hole 316, and a portion of the second housing 21 protrudes from the second opening 312. Illustrated, there are two second buckles 212 and two locking holes 316. When the sealing cover 13 is in the second position, the two second buckles 212 engage with the two second locking holes 316 in a one-to-one correspondence; when the sealing cover 13 is in the first position, the two second buckles 212 disengage from the two second locking holes 316. With this configuration, when it is necessary to remove the reservoir 2 from the third housing 31 of the power assembly 3, simply pull the second housing 21 downwards to disengage the two second clips 212 from the two second clip holes 316 and disengage the nozzle 221 from the inside of the sealing cover 13. This allows the entire reservoir 2 to be removed from the first opening 311 of the third housing 31. When it is necessary to install the second housing 21 of the reservoir 2 into the third housing 31 of the power assembly 3, the second housing 21 can be inserted into the receiving cavity 310 of the third housing 31 from the first opening 311 of the third housing 31. This allows the nozzle 221 to pass through the receiving cavity 310, the through hole 313, and the installation channel 103 in sequence and be inserted into the inside of the sealing cover 13. The corresponding second clips 212 then engage with the corresponding second clip holes 316, thus completing the installation process of the reservoir 2.

[0099] Further, please refer to Figure 1-2 , Figure 4 , Figure 7 and Figure 11 In some optional embodiments of this application, the outer wall of the second housing 21 corresponding to the second opening 312 is provided with exposed anti-slip texture 213. The structure of the anti-slip texture 213 can be a groove and / or a protrusion. In this embodiment, the anti-slip texture 213 can increase the friction between the user's fingers and the second housing 21, thereby making it easier for the user to push and pull the second housing 21 with their fingers without easily causing "slipping", so as to drive the sealing cover 13 to slide between the first position and the second position or to detach the liquid reservoir 2 from the atomizer 1 and the power supply assembly 3.

[0100] Furthermore, in some optional embodiments of this application, the specific structural form of the atomizer 1 can be as follows:

[0101] Please refer to Figure 1-2 , Figure 4 , Figure 6-9 and Figure 12-13The first housing 11 includes an outer shell portion 111 (the material of the outer shell portion 111 may be acrylic), a base 112 (the material of the base 112 may be silicone or rubber), a connector 113 (the material of the connector 113 may be plastic), and an air duct 114 (the material of the air duct 114 may be plastic or stainless steel) having at least a partial airflow passage 102. The base 112 is sealed to the bottom of the outer shell portion 111, and the air duct 114 is located inside the outer shell portion 111 with one end sealed to the top of the outer shell portion 111 and the other end sealed to the base 112 (exemplarily, the upper end of the air duct 114 is sealed to the top of the outer shell portion 111, and the lower end of the air duct 114 is sealed to the base 112). The outer shell portion 111, the base 112, and the air duct 114 together define a first storage area. The cavity 101 and the air passage 114 have a liquid inlet hole 1140 on their side walls, which communicates with the first storage cavity 101. The atomizing core 12 is installed in the air passage 114 and covers the liquid inlet hole 1140 (that is, the atomizing core 12 is connected to the first storage cavity 101 through the liquid inlet hole 1140). The connector 113 includes a pipe portion 1131 with an installation channel 103. The pipe portion 1131 passes through the base 112 along the thickness direction and forms a sealed connection with the base 112. A third liquid passage hole 11310 is provided on the side wall of the pipe portion 1131. The third liquid passage hole 11310 is located in the first storage cavity 101 and communicates with the first storage cavity 101. Along the height direction of the outer shell portion 111, there is a minimum vertical distance L between the hole wall of the third liquid passage hole 11310 and the bottom wall of the first storage cavity 101 (e.g., ...). Figure 13 As shown), the minimum vertical spacing L is greater than or equal to 1 mm (in some specific application scenarios, the size of L can optionally be set to 1 mm ≤ L ≤ 8 mm); when the sealing cover 13 is in the second position, the first liquid passage 131 is connected to the third liquid passage 11310, thereby making the second liquid passage 2210 connected to the first storage cavity 101.

[0102] In this embodiment, the above structural design helps to improve the ease of assembly of the atomizer 1. Specifically, when manufacturing the atomizer 1 of this embodiment, the atomizing core 12 is first installed into the airway tube 114, and the outer wall of the atomizing core 12 covers the liquid inlet hole 1140 of the airway tube 114; then the airway tube 114 with the atomizing core 12 is inserted into the upper side of the base 112; next, the sealing cap 13 is installed from the upper port of the pipe section 1131 into the mounting channel 103 of the pipe section 1131; then the connector 113 with the sealing cap 13 is installed on the lower side of the base 112, and the upper end of the pipe section 1131 protrudes from the upper end face of the base 112; then the base 112 with the connector 113 and the airway tube 114 is installed into the bottom of the outer shell section 111, and the upper end of the airway tube 114 is engaged with the top of the outer shell section 111; finally, the mouthpiece 14 is installed on the top of the outer shell section 111. This completes the assembly process of the atomizer 1, making it relatively convenient to operate. Furthermore, in this embodiment, by setting the minimum vertical distance L between the wall of the third liquid passage 11310 and the bottom wall of the first storage chamber 101 to be no less than 1mm, it makes it more difficult for the small amount of atomizer liquid remaining in the first storage chamber 101 to leak to the outside through the third liquid passage 11310, the first liquid passage 131, and the mounting channel 103 during the process where the atomizer liquid in the first storage chamber 101 of the atomizer 1 and the second storage chamber 201 of the liquid reservoir 2 are completely consumed and a new liquid reservoir 2 needs to be replaced.

[0103] In this embodiment, it should be noted that the number of the first liquid passage hole 131, the second liquid passage hole 2210, and the third liquid passage hole 11310 can be determined according to actual usage requirements, and this embodiment does not impose specific limitations on this. Optionally, two of each of the first liquid passage hole 131, the second liquid passage hole 2210, and the third liquid passage hole 11310 are provided. The two first liquid passage holes 131 are arranged with a relative interval, the two second liquid passage holes 2210 are arranged with a relative interval, and the two third liquid passage holes 11310 are arranged with a relative interval. Each first liquid passage hole 131 is connected to each second liquid passage hole 2210 in a one-to-one correspondence. When the sealing cover 13 is in the second position, each first liquid passage hole 131 is connected to each third liquid passage hole 11310 in a one-to-one correspondence. This arrangement is beneficial for the faster introduction of the atomizing liquid in the second storage chamber 201 into the first storage chamber 101 for replenishment during the atomizing liquid replenishment operation.

[0104] Further, please refer to Figure 4 and Figure 8In some optional embodiments of this application, the volume of the second storage chamber 201 can be set to 2.5 to 5.5 times the volume of the first storage chamber 101. For example, assuming the volume of the first storage chamber 101 of the atomizer 1 is 2 ml (that is, it can store 2 ml of atomizing liquid), then the volume of the second storage chamber 201 of the reservoir 2 can be 5 ml to 11 ml, which is equivalent to indirectly increasing the volume of the atomizer 1 by 2.5 to 5.5 times. This setting not only allows the reservoir 2 to repeatedly replenish the atomizer 1 with atomizing liquid (at least 3 times), but also avoids the reservoir 2's volume being set too large, which would result in an excessively large overall size of the atomizing device and affect the user's portability.

[0105] Furthermore, in some optional embodiments of this application, the circumferential portion of the first housing 11 corresponding to the first storage cavity 101 is made of a transparent material (such as glass, acrylic, or other transparent materials). This arrangement allows the user to easily observe the atomizing liquid content in the first storage cavity 101 at any time, intuitively determining whether the atomizing liquid in the first storage cavity 101 has been completely consumed and whether the first storage cavity 101 is full of atomizing liquid during the process of replenishing the atomizer 1 with atomizing liquid through the reservoir 2.

[0106] Furthermore, to facilitate the electrical connection between the atomizer coil 12 and the control circuit board 33 after inserting the bottom of the atomizer 1 into the receiving slot 314 of the third housing 31, please refer to... Figure 8 as well as Figure 11-12 In some optional embodiments of this application, the atomizer 1 further includes a first electrode assembly 15 electrically connected to the atomizing core 12. The first electrode assembly 15 is exposed on the bottom wall of the first housing 11. The power supply assembly 3 further includes a second electrode assembly 35 electrically connected to the control circuit board 33. The second electrode assembly 35 is exposed in the receiving groove 314, and the first electrode assembly 15 and the second electrode assembly 35 are in electrical contact. In specific implementations, the first electrode assembly 15 can be in the form of a conductive pin, and the second electrode assembly 35 can be in the form of a conductive spring pin.

[0107] Furthermore, to facilitate user charging of battery 32 in power assembly 3, please refer to... Figure 4 , Figure 6 and Figure 8 In some optional embodiments of this application, the power supply assembly 3 further includes a charging interface 34 electrically connected to the control circuit board 33, and the outer wall of the third housing 31 is provided with a socket 317 corresponding to the charging interface 34.

[0108] Correspondingly, embodiments of this application also provide a liquid storage device, which is used in conjunction with the atomizing body (such as...) in any of the above embodiments of the vapor generation device. Figure 6 and Figure 12-13 (As shown) can be detachably combined and used, and the liquid storage device is the liquid storage tank 2 in the vapor generating device of any of the above embodiments (such as... Figure 1-5 , Figure 7-11 as well as Figure 14-21 (As shown).

[0109] In this embodiment, the liquid storage device provided can be integrated with the atomizing body mentioned in any of the above embodiments for use. Therefore, it can not only replenish the atomizing liquid stored in the atomizer 1 after it is consumed by the atomizing core 12, allowing the atomizer 1 to be used repeatedly for a long time, but also, when the liquid storage device 2 is removed from the atomizer 1, it can drive the sealing cap 13 to a first position that isolates the first liquid passage 131 from the first storage chamber 101, thereby preventing the atomizing liquid remaining in the first storage chamber 101 of the atomizer 1 from leaking to the outside through the installation channel 103. It should be noted that other contents of the liquid storage device provided in this embodiment can be referred to the description of the liquid storage device 2 in the above-mentioned vapor generation device embodiments, and will not be repeated here.

[0110] Correspondingly, embodiments of this application also provide an atomizing device, which is used in conjunction with the liquid reservoir 2 in the vapor generation device of any of the above embodiments (e.g., Figure 1-5 , Figure 7-11 as well as Figure 14-21 (As shown) can be detachably combined and used, and the atomizing device is the atomizing body in the vapor generating device of any of the above embodiments (such as...). Figure 6 and Figure 12-13 (As shown).

[0111] In this embodiment, the atomizing device provided can be integrated with the liquid reservoir 2 mentioned in any of the above embodiments. Therefore, it can replenish the atomizing liquid in the first storage chamber 101 after the atomizing core 12 has consumed it, allowing the atomizer 1 to be used repeatedly for a long time. Furthermore, when the liquid reservoir 2 is removed from the atomizer 1, the sealing cap 13 inside the atomizer 1 can be driven by the liquid outlet 221 of the liquid reservoir 2 to a first position where the first liquid passage 131 is isolated from the first storage chamber 101, thus preventing the atomizing liquid remaining in the first storage chamber 101 from leaking to the outside through the installation channel 103. It should be noted that other aspects of the atomizing device provided in this embodiment can be found in the description of the atomizing body in the above-mentioned vapor generation device embodiments, and will not be repeated here.
