Description

Technical Field

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

[0002] An electronic atomizing device is an electronic device that can vaporize stored e-liquid, medicine, or other atomizing liquids into vapor through electric heating. An electronic atomizing device typically includes an atomizer and a power supply component. The atomizer generally includes a first reservoir for storing the atomizing liquid and an atomizing core for absorbing the atomizing liquid and vaporizing it into vapor. The power supply component is used to supply power to the atomizing core.

[0003] In related technologies, the volume of the first reservoir chamber of an atomizer is typically designed to be relatively small (usually 2ml), making it impossible to pre-fill with a large amount of atomized liquid at the factory, thus resulting in a short continuous usage time for the atomizer. To extend the atomizer's lifespan, related technologies can equip the atomizer with a larger, replaceable reservoir. Once the atomizer's stored liquid is depleted by the coil, the user can replenish the first reservoir chamber with liquid pre-filled from the second reservoir, allowing the atomizer to continue operating. However, these electronic atomizing devices equipped with reservoirs generally suffer from the following problems:

[0004] The process of replenishing the atomizing liquid from the second reservoir of the reservoir to the first reservoir of the atomizer typically involves first opening the valve connecting the two reservoirs, thus establishing communication between them. Then, the entire electronic atomizing device is inverted, allowing gravity to draw the atomizing liquid from the second reservoir into the first reservoir. After replenishment, the valve is closed to isolate the two reservoirs and prevent backflow of the atomizing liquid from the first reservoir into the second. Finally, the entire electronic atomizing device is upright for subsequent use. This replenishment process is relatively cumbersome. Utility Model Content

[0035] Compared with the prior art, this application has at least the following beneficial effects:

[0036] In the technical solution of this application, when the atomizing liquid in the first liquid storage chamber of the atomizer is consumed by the atomizing core and needs to be replenished, the driving component can be operated to drive the piston cylinder to reciprocate relative to the column along the height direction of the second housing. During the reciprocating motion of the piston cylinder, when the piston cylinder slides away from the liquid inlet end of the first liquid guiding channel, the second valve body closes the liquid outlet end of the liquid outlet channel. At the same time, the volume of the space along the path connecting the liquid outlet channel and the first liquid guiding channel increases, creating a negative pressure in the space connecting the liquid outlet channel and the first liquid guiding channel. Under the action of this negative pressure, the first valve body opens the liquid inlet end of the first liquid guiding channel and... The atomized liquid in the second storage chamber can be "drawn" into the space connecting the outlet channel and the first liquid guiding channel for storage. When the piston cylinder slides along the direction close to the inlet end of the first liquid guiding channel, the first valve body closes the inlet end of the first liquid guiding channel. At the same time, the volume of the space connecting the outlet channel and the first liquid guiding channel will decrease, which will increase the air pressure in the space connecting the outlet channel and the first liquid guiding channel. Under the action of this increased air pressure, the second valve body opens the outlet end of the outlet channel, so that the atomized liquid stored in the space connecting the outlet channel and the first liquid guiding channel can be "squeezed" towards the outlet hole and sprayed into the first storage chamber of the atomizer from the outlet hole for replenishment. Therefore, in the technical solution of this application, when the first liquid storage chamber of the atomizer needs to be replenished with atomizing liquid, only the driving component needs to be operated to pump the atomizing liquid in the second liquid storage chamber of the liquid storage chamber into the first liquid storage chamber of the atomizer for replenishment, without having to invert the entire electronic atomizing device. This simplifies the liquid replenishment operation of the electronic atomizing device and makes it more convenient for users. In other words, the electronic atomizing device provided in this application embodiment allows users to easily replenish the atomizing liquid in the second liquid storage chamber of the liquid storage chamber into the first liquid storage chamber of the atomizer, thereby improving the user experience.

[0061] Please refer to Figure 1-4 and Figure 7 One embodiment of this application provides an electronic atomizing device, which includes an atomizing body and a liquid reservoir 2. The atomizing body includes an atomizer 1, which includes a first housing 11 and an atomizing core 12. The liquid reservoir 2 includes a second housing 21, a pump assembly 23, and an outlet pipe 22 with an outlet channel 2202, wherein:

[0062] The first housing 11 is provided with an airflow channel 102, an installation channel 11311 spaced apart from the airflow channel 102, and a first liquid storage chamber 101 for storing atomizing liquid. The atomizing core 12 is installed in the first housing 11 and communicates with the first liquid storage chamber 101, so that the atomizing core 12 can draw atomizing liquid from the first liquid storage chamber 101, heat and atomize it to produce a vapor that can be inhaled by the user. Moreover, the atomizing core 12 is located on the airflow path of the airflow channel 102, so that the vapor generated by the atomizing core 12 can be carried away by the suction airflow formed in the airflow channel 102 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 mouthpiece 13 (the mouthpiece 13 can be made of plastic) that communicates with the airflow channel 102. When the user bites the mouthpiece 13 to inhale, a suction airflow can be formed in the airflow channel 102.

[0063] The interior of the second housing 21 is provided with a second liquid storage chamber 201 for storing atomizing liquid and a receiving chamber 202 separated from the second liquid storage chamber 201. The receiving chamber 202 has a structure along the height direction of the second housing 21 (i.e., Figure 2 and Figure 7 A column 211 extends in the vertical direction. The interior of the column 211 has a first liquid guiding channel 2110 extending along the axial direction of the column 211. The liquid inlet of the first liquid guiding channel 2110 is connected to the second liquid storage chamber 201.

[0064] One end of the liquid outlet pipe 22 is provided with a liquid outlet nozzle 221, and the other end is connected to the second housing 21. The liquid outlet nozzle 221 has a liquid outlet hole 2210 on its circumferential side wall for discharging the atomized liquid in the second liquid storage chamber 201. At least a portion of the liquid outlet pipe 22 is detachably and sealed in the installation channel 11311, and the liquid outlet hole 2210 of the liquid outlet nozzle 221 is connected to the first liquid storage chamber 101 of the atomizer 1.

[0065] The pump assembly 23 includes a piston cylinder 233, a first valve body 231, a second valve body 232, and a drive component 234. The piston cylinder 233 is slidably mounted in the receiving cavity 202 along the height direction of the second housing 21. The interior of the piston cylinder 233 has a second liquid guiding channel 2330 extending axially along the piston cylinder 233. One end of the piston cylinder 233 is sealed to the column body 211. The second liquid guiding channel 2330 is connected to the liquid outlet end of the first liquid guiding channel 2110 and the liquid inlet end of the liquid outlet channel 2202, respectively. (Illustrated, as shown...) Figure 7As shown, a connecting channel 260 is provided in the top of the second housing 21. The first liquid guiding channel 2110, the second liquid guiding channel 2330, the connecting channel 260, and the liquid outlet channel 2202 are connected in sequence to form a liquid supply channel 26. The liquid inlet end of the first liquid guiding channel 2110 can be defined as the liquid suction end 261 of the liquid supply channel 26, and the liquid outlet end of the liquid outlet channel 2202 can be defined as the liquid spraying end 262 of the liquid supply channel 26.

[0066] The first valve body 231 is disposed within the first liquid guiding channel 2110. The first valve body 231 is used to open and close the liquid inlet end of the first liquid guiding channel 2110, as illustrated. Figure 2 and Figure 7 As shown, the first valve body 231 has a spherical structure. It can be understood that when the first valve body 231 opens the inlet end of the first liquid guiding channel 2110, the liquid supply channel 26 is connected to the second liquid storage chamber 201. When the first valve body 231 closes the inlet end of the first liquid guiding channel 2110, the liquid supply channel 26 is isolated from the second liquid storage chamber 201. That is, the first valve body 231 can act as a one-way valve.

[0067] The second valve body 232 is disposed inside the liquid outlet 221. The second valve body 232 is used to open and close the liquid outlet end of the liquid outlet channel 2202, as illustrated. Figure 2 and Figure 7 As shown, the second valve body 232 has a spherical structure. It can be understood that when the second valve body 232 opens the outlet end of the outlet channel 2202, the outlet end of the outlet channel 2202 is connected to the outlet hole 2210, thereby connecting the supply channel 26 to the first storage chamber 101. When the second valve body 232 closes the outlet end of the outlet channel 2202, the outlet end of the outlet channel 2202 is isolated from the outlet hole 2210, thereby isolating the supply channel 26 from the first storage chamber 101. That is, the second valve body 232 can function as a one-way valve.

[0068] The drive component 234 is connected to the piston cylinder 233, and at least a portion of the drive component 234 is exposed outside the second housing 21 to allow the user to operate the drive component 234. The drive component 234 is configured to operably drive the piston cylinder 233 to slide relative to the column 211 along the height direction of the second housing 21. When the drive component 234 drives the piston cylinder 233 to slide in a direction away from the inlet end of the first liquid guiding channel 2110, 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 channel. The outlet end of channel 2202 is used to "draw" the atomized liquid in the second liquid storage chamber 201 into the liquid supply channel 26 for storage; when the driving component 234 drives the piston cylinder 233 to slide along the direction close to the inlet end of the first liquid guide channel 2110, the first valve body 231 closes the inlet end of the first liquid guide channel 2110 and the second valve body 232 opens the outlet end of the outlet channel 2202 to prevent the atomized liquid in the liquid supply channel 26 from flowing back into the second liquid storage chamber 201 and to pump the atomized liquid stored in the liquid supply channel 26 into the first liquid storage chamber 101 for replenishment.

[0069] In this embodiment, based on the above structural design, the operating principle of the electronic atomization device provided in this embodiment is as follows:

[0070] When the atomizing liquid in the first storage chamber 101 of the atomizer 1 is depleted by the atomizing core 12 and needs to be replenished, the drive component 234 can be operated to drive the piston cylinder 233 to reciprocate relative to the column 211 along the height direction of the second housing 21. During the reciprocating motion of the piston cylinder 233, when the piston cylinder 233 slides away from the suction end 261, the second valve body 232 closes the spray end 262. At the same time, the volume of the liquid supply channel 26 increases, creating a negative pressure in the liquid supply channel 26. Under the action of this negative pressure, the first valve body 231 opens the suction end 261, allowing the atomizing liquid in the second storage chamber 201 to be "drawn" into the liquid supply channel 26 for storage. When the piston cylinder 233 slides closer to the suction end 261, the first valve body 231 closes the suction end 261. Meanwhile, the volume of the liquid supply channel 26 will decrease, causing the air pressure inside the liquid supply channel 26 to increase. Under the action of this increased air pressure, the second valve body 232 opens the liquid outlet end of the liquid outlet channel 2202, allowing the atomized liquid stored in the liquid supply channel 26 to be "squeezed" towards the liquid outlet 2210 and sprayed from the liquid outlet 2210 into the first liquid storage chamber 101 of the atomizer 1 for replenishment. After replenishment, the operation of the drive component 234 is stopped, causing the piston cylinder 233 to stop moving. At this time, both the first valve body 231 and the second valve body 232 are in the closed state (that is, the first valve body 231 is in the state of closing the liquid suction end 261, and the second valve body 232 is in the state of closing the liquid spray end 262), so that the atomized liquid in the first liquid storage chamber 101 cannot flow back into the liquid supply channel 26 and the atomized liquid in the liquid supply channel 26 cannot flow back into the second liquid storage chamber 201.

[0071] Therefore, in the technical solution of this embodiment, when the atomizing liquid in the first liquid storage chamber 101 of the atomizer 1 is consumed by the atomizing core 12 and needs to be replenished, the atomizing liquid in the second liquid storage chamber 201 of the liquid storage 2 can be pumped into the first liquid storage chamber 101 of the atomizer 1 for replenishment simply by operating the driving component 234, without having to invert the entire electronic atomizing device (it can be understood that if the entire electronic atomizing device is inverted, the electronic atomizing device will be in a position with the mouthpiece 13 facing down). This simplifies the liquid replenishment operation of the electronic atomizing device and makes it more convenient for users. In other words, the electronic atomizing device provided in this embodiment allows users to easily replenish the atomizing liquid in the second liquid storage chamber 201 of the liquid storage 2 into the first liquid storage chamber 101 of the atomizer 1, thereby improving the user experience.

[0072] Further, please refer to Figure 1-4 and Figure 12-13In 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., Figure 1-4 One end of the mounting channel 11311 (in the vertical direction) is connected to the first housing 11. The battery 32 and 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, enabling the atomizing core 12 to perform atomization. The mounting channel 11311 extends along the height direction of the first housing 11 (i.e., in the vertical direction). Figure 2-3 as well as Figure 12-13 The third housing 31 is provided with a through hole 313 through which the liquid outlet 221 passes and a receiving cavity 310 for mounting the second housing 21. The through hole 313 is provided corresponding to the mounting channel 11311, 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, and at least a portion of the drive component 234 is exposed in the third housing 31. 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 the user's subsequent use of the electronic atomizing device for inhalation.

[0073] 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.

[0074] 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.

[0075] Exemplary, in some optional embodiments, the detachable connection between the second housing 21 and the third housing 31 can be a snap-fit ​​connection, specifically, as shown in... Figure 1-5 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 lower end of the second opening 312 is an open end (illustratively, as shown). Figure 4 As shown, the second opening 312 is inverted "U" shape. A portion of the second housing 21 is located inside the receiving cavity 310, and a portion of the second housing 21 is exposed from the second opening 312. A portion of the driving component 234 is exposed in the second housing 21 at the part corresponding to the second opening 312 (illustratively, this part matches the second opening 312 to improve the aesthetic appearance of the electronic atomizing device). The end of the second housing 21 facing away from the liquid outlet pipe 22 (i.e., the bottom of the second housing 21) is located corresponding to the first opening 311. The second housing 21 has at least one first buckle 212 on its outer wall along its circumference, and the receiving cavity 310 has at least one first locking hole 315 that matches the first buckle 212. At least one first buckle 212 and at least one first locking hole 315 are engaged, thereby enabling the second housing 21 and the third housing 31 to be stably connected together. When the atomizing liquid in the first liquid storage chamber 101 and the second liquid storage chamber 201 is exhausted and a new liquid storage device 2 needs to be replaced, simply pull the second housing 21 downwards to disengage the first clips 212 from the first locking holes 315 and allow the nozzle 221 to sequentially disengage from the installation channel 11311 and the through hole 313. This allows the entire liquid storage device 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 new liquid storage device 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. This allows the nozzle 221 to pass through the receiving cavity 310 and the through hole 313, extending into the installation channel 11311 and connecting with the first liquid storage chamber 101. The corresponding first clips 212 then engage with the corresponding first locking holes 315, thus completing the installation process of the liquid storage device 2. In other words, the installation and removal of the reservoir 2 can be completed simply by plugging and unplugging it, which is quite convenient.

[0076] Exemplary, in some optional embodiments, the connection between the first housing 11 and the third housing 31 can be a detachable snap-fit ​​connection, specifically, as shown in... Figure 3-4 and Figure 12-13As shown, the third housing 31 has a receiving groove 314 located above the through hole 313. The top side wall of the third housing 31 is provided with a second latch 316. The first housing 11 has a second latch 1110 on its circumferential side wall that is adapted to the second latch 316. The bottom of the first housing 11 is inserted into the receiving groove 314, and the second latch 1110 is engaged with the second latch 316, so that the first housing 11 and the third housing 31 can be stably connected together. When atomizer 1 needs to be replaced due to damage, simply pull atomizer 1 upwards to disengage the second clip 1110 from the second clip hole 316, thus detaching atomizer 1 from the third housing 31 of the power assembly 3. When a new atomizer 1 needs to be installed on the power assembly 3, simply insert the bottom of atomizer 1 into the receiving groove 314 of the third housing 31, allowing the second clip 1110 to engage with the second clip hole 316, thus completing the installation process of atomizer 1. In other words, the installation and removal of atomizer 1 can be completed simply by inserting and removing it, making the operation quite convenient.

[0077] Further, please refer to Figure 1 and Figure 4 In some optional embodiments of this application, the second housing 21 is further provided with exposed anti-slip texture 213 at the portion corresponding to the second opening 312. The structure of the anti-slip texture 213 can be a groove and / or a protrusion. In this embodiment, the anti-slip texture 213 increases the friction between the user's fingers and the second housing 21, thereby making it easier for the user to pull the second housing 21 by hand without slipping, so as to detach the liquid reservoir 2 from the atomizing body.

[0078] Furthermore, in some optional embodiments of this application, the drive component 234 can be an electrically driven structure. Specifically, the drive component 234 includes a push-button switch (not shown) exposed in the second housing 21, a servo linear motor (not shown), and a power supply (not shown) installed in the receiving cavity 202 of the second housing 21. The output shaft of the servo linear motor is fixedly connected to the bottom of the piston cylinder 233, and the servo linear motor is electrically connected to the power supply and the push-button switch respectively. With this configuration, the user can control the servo linear motor to be powered on or off by pressing the push-button switch. When the servo linear motor is powered on, it drives the piston cylinder 233 to reciprocate, thereby pumping the atomized liquid in the second liquid storage cavity 201 into the first liquid storage cavity 101 for replenishment.

[0079] Furthermore, in some alternative embodiments of this application, the drive component 234 may also be a manually operated structure. For details, please refer to... Figure 2 and Figure 7The driving component 234 includes a push member 2341 and an elastic member 2342. One end of the push member 2341 is connected to the piston cylinder 233. The end of the push member 2341 facing away from the piston cylinder 233 is exposed in the second housing 21 and in the third housing 31 (illustratively, the second housing 21 has a through hole 214 extending along the height direction of the second housing 21 at the location corresponding to the second opening 312. One end of the push member 2341 is fixedly connected to the outer wall of the piston cylinder 233 along its circumferential direction, and the other end passes through the through hole 214 and is exposed in the third housing 31). The push member 2341 is configured to drive the piston cylinder 233 to slide in the direction close to the inlet end of the first liquid guiding channel 2110 when subjected to external force, so that the first valve body 231 closes the inlet end of the first liquid guiding channel 2110 and the second valve body 232 opens the outlet end of the outlet channel 2202; one end of the elastic member 2342 is connected to the piston cylinder 233. With the piston cylinder 233 fixed and the other end fixed relative to the column 211 (specifically, in some optional embodiments, one end of the elastic element 2342 can abut against the lower end face of the piston cylinder 233 and the other end can abut against the bottom wall of the receiving cavity 202; in other optional embodiments, one end of the elastic element 2342 can also abut against the inner wall of the piston cylinder 233 and the other end can abut against the inner wall of the column 211), the elastic element 2342 is configured to drive the piston cylinder 233 to reset when the external force applied to the push member 2341 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 outlet channel 2202. In specific implementation, the elastic element 2342 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 restrictions on this.

[0080] In this embodiment, based on the above structural design, the operating principle of the electronic atomization device provided in this embodiment is as follows:

[0081] Before the first operation of the pusher 2341, both the first valve body 231 and the second valve body 232 are in the closed state, and there is no atomizing liquid stored in the liquid supply channel 26.

[0082] When the atomizing liquid in the first reservoir 101 of the atomizer 1 is consumed by the atomizing core 12 for the first time and needs to be replenished, the pusher 2341 can be repeatedly pushed with a finger. When the user pushes the pusher 2341 downwards for the first time, the pusher 2341 drives the piston cylinder 233 downwards. During the downward movement of the piston cylinder 233, the elastic element 2342 is gradually compressed. Simultaneously, the volume of the liquid supply channel 26 decreases (specifically, the volume of the path connecting the first liquid guide channel 2110 and the second liquid guide channel 2330 decreases), thus… This causes the air pressure in the liquid supply channel 26 to increase. Under the action of this increased air pressure, the second valve body 232 is lifted up, and the spray end 262 of the liquid supply channel 26 is connected to the outlet hole 2210 of the outlet nozzle 221. Since there is no atomizing liquid stored in the liquid supply channel 26 at this time, no atomizing liquid will be sprayed into the first liquid storage chamber 101 from the outlet hole 2210. In addition, during this process, when the air pressure in the liquid supply channel 26 and the air pressure in the first liquid storage chamber 101 reach equilibrium, the second valve body 232 will fall back to the state of closing the spray end 262 under its own gravity.

[0083] When the user first removes the force applied to the pusher 2341, under the elastic restoring force of the elastic element 2342, the piston cylinder 233 drives the pusher 2341 to move upward together. During the upward movement of the piston cylinder 233, the volume of the liquid supply channel 26 will increase (specifically, the volume of the space along the path connecting the first liquid guide channel 2110 and the second liquid guide channel 2330 will increase), thereby creating a negative pressure in the liquid supply channel 26. Under the action of this negative pressure, the first valve body 231 is "sucked up" and the first liquid guide channel 2110 is connected to the second liquid storage chamber 201, so that the atomized liquid in the second liquid storage chamber 201 can be "sucked" into the first liquid guide channel 2110 of the liquid supply channel 26 for storage. Until the air pressure in the liquid supply channel 26 and the air pressure in the second liquid storage chamber 201 reach equilibrium, the first valve body 231 will fall back to the state of closing the suction end 261 under its own gravity. Thus, by repeatedly pushing the pusher 2341, the liquid supply channel 26 can store more and more atomized liquid (specifically, each time the pusher 2341 completes a round trip, the liquid supply channel 26 will "draw in" a certain amount of atomized liquid from the second liquid storage chamber 201), until the amount of atomized liquid in the liquid supply channel 26 reaches a certain level and the pusher 2341 is pushed downwards, the atomized liquid in the liquid supply channel 26 can push up the second valve body 232 and be sprayed into the first liquid storage chamber 101 through the liquid outlet 2210 for replenishment. In this way, each time the pusher 2341 is pushed down, a certain amount of atomized liquid can be sprayed into the first liquid storage chamber 101 for replenishment, until the atomized liquid in the second liquid storage chamber 201 and the liquid supply channel 26 is consumed.

[0084] Therefore, in the technical solution of this embodiment, when the atomizing liquid in the first liquid storage chamber 101 of the atomizer 1 is consumed by the atomizing core 12 and needs to be replenished, the user only needs to push the pusher 2341 to pump the atomizing liquid in the second liquid storage chamber 201 of the liquid storage 2 into the first liquid storage chamber 101 of the atomizer 1 for replenishment, without having to invert the entire electronic atomizing device. This simplifies the liquid replenishment operation of the electronic atomizing device, allowing the user to easily replenish the atomizing liquid in the second liquid storage chamber 201 into the first liquid storage chamber 101, thus improving the user experience.

[0085] In this embodiment, it should be noted that, compared with the above-mentioned electric drive component 234, the manual drive component 234 in this embodiment has the advantages of simple structure and low cost, which helps to reduce the usage cost of the liquid reservoir 2.

[0086] In this embodiment, it should also be noted that the elastic element 2342 allows the piston cylinder 233 to automatically reset without requiring manual reset by the user (it can be understood that if the elastic element 2342 is removed, the user needs to push the pusher 2341 upwards after pushing the pusher 2341 downwards to drive the piston cylinder 233 back to its initial position). This allows the user to more conveniently and effortlessly drive the piston cylinder 233 to reciprocate, continuously pumping the atomized liquid in the second liquid storage chamber 201 into the first liquid storage chamber 101 for replenishment.

[0087] Further, please refer to Figure 2 and Figure 7-8In some optional embodiments of this application, the piston cylinder 233 includes a cylinder 2333 made of a rigid material (such as stainless steel or rigid plastic), a first sealing sleeve 2331 made of a sealing material (such as silicone, rubber, or silicone rubber), and a second sealing sleeve 2332 made of a sealing material (such as silicone, rubber, or silicone rubber). The cylinder 2333, the first sealing sleeve 2331, and the second sealing sleeve 2332 are all hollow and interconnected. The first sealing sleeve 2331 is fixedly sleeved on one side of the cylinder 2333. The first sealing sleeve 2331 is in contact with the inner wall of the receiving cavity 202 along its circumferential outer wall. One end of the second sealing sleeve 2332 is fixedly sleeved on the end of the cylinder 2333 away from the first sealing sleeve 2331, and the other end of the second sealing sleeve 2332 is sealed and sleeved on the outer wall of the column 211, with the second sealing sleeve 2332 in contact with the inner wall of the receiving cavity 202 along its circumferential outer wall. One end of the elastic element 2342 abuts against the inner wall of the cylinder 2333, and the other end abuts against the inner wall of the column 211. This arrangement facilitates the sealing fit between the piston cylinder 233 and the receiving cavity 202, as well as between the piston cylinder 233 and the column 211, and allows the piston cylinder 233 to reciprocate smoothly relative to the column 211 within the receiving cavity 202.

[0088] Further, please refer to Figure 7-8 In some optional embodiments of this application, the inner wall surface of the cylinder 2333 facing the column 211 is provided with a sleeve portion 23331 extending axially along the cylinder 2333, and the inner peripheral wall of the column 211 is provided with a protrusion portion 2111. The elastic element 2342 is a spring, one end of which extends into the sleeve portion 23331 and abuts against the inner wall surface of the cylinder 2333 facing the column 211, and the other end of which extends into the column 211 and abuts against the end face of the protrusion portion 2111 facing the sleeve portion 23331. With this configuration, the sleeve portion 23331 can position the upper end of the elastic element 2342, and the column 211 can position the lower end of the elastic element 2342, thereby enabling the elastic element 2342 to elastically extend and retract more smoothly. This facilitates smoother reciprocating motion of the piston cylinder 233 by the user and reduces the likelihood of jamming.

[0089] Further, please refer to Figure 2-4 and Figure 7In some optional embodiments of this application, the inner diameter of the installation channel 11311 is gradually reduced in the direction away from the second housing 21, 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 nozzle 221, the outer diameter of the pipe section 222 is gradually reduced in the direction away from the second housing 21, and at least a portion of the pipe section 222 is fitted into the installation channel 11311. This design serves two purposes. First, the installation channel 11311, whose inner diameter gradually decreases from bottom to top and matches the outer diameter of the pipe section 222, can provide guidance, allowing the user to insert the outlet pipe 22 into the installation channel 11311 more smoothly during the installation of the liquid reservoir 2. 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 and less prone to damage during injection molding.

[0090] Further, please refer to Figure 2-3 and Figure 7 In some optional embodiments of this application, at least one sealing ring 25 is fitted on the outer wall of the liquid outlet pipe 22, located between the liquid outlet nozzle 221 and the second housing 21, and the at least one sealing ring 25 contacts the inner wall of the mounting channel 11311. This arrangement not only enables the plug-in connection between the liquid outlet pipe 22 and the atomizer 1, but also improves the sealing performance between the liquid outlet pipe 22 and the mounting channel 11311, making it difficult for the atomized liquid in the first liquid storage chamber 101 to leak to the outside through the mounting gap between the liquid outlet pipe 22 and the mounting channel 11311.

[0091] Further, please refer to Figure 2 as well as Figure 4-11In some optional embodiments of this application, the liquid reservoir 2 further includes a sealing member 24 fixedly sleeved on the liquid outlet 221 (exemplarily, the liquid outlet pipe 22 has a limiting groove recessed on its outer wall along its circumference, adjacent to the liquid outlet 221, the limiting groove being an annular groove, the lower end inner wall of the sealing member 24 has a limiting protrusion 242 adapted to the limiting groove, the limiting protrusion 242 is engaged in the limiting groove, and the sealing member 24 at least covers the outer wall of the liquid outlet pipe 22 along its circumference), the sealing member 24 is sealed and fitted with the installation channel 11311 (specifically, the outer wall of the sealing member 24 along its circumference is in close contact with the inner wall of the installation channel 11311), the sealing member 24 has a first liquid passage hole 241 connected to the first liquid storage cavity 101 on its side wall along its circumference, the first liquid passage hole 241 is correspondingly connected to the liquid outlet hole 2210. This configuration, while enabling plug-in connection between the outlet pipe 22 and the atomizer 1, also improves the sealing between the outlet pipe 22 and the mounting channel 11311, making it difficult for the atomized liquid in the first liquid storage chamber 101 to leak to the outside through the installation gap between the outlet pipe 22 and the mounting channel 11311. It should be noted that, in specific implementations, the material of the sealing element 24 can be silicone, rubber, or silicone rubber. The upper surface of the sealing element 24 can be closed or open; this embodiment does not limit this. When the upper surface of the sealing element 24 is closed, the structure of the sealing element 24 is a sealing cap with a first liquid passage hole 241; when the upper surface of the sealing element 24 is open, the structure of the sealing element 24 is a sealing sleeve with a first liquid passage hole 241.

[0092] Furthermore, in some optional embodiments of this application, the specific structural form of the atomizer 1 can be as follows:

[0093] Please refer to Figure 2-3 , Figure 9-10 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 of the air duct 114 sealed to the top of the outer shell portion 111. The outer shell 111, the base 112, and the air duct 114 together define the first liquid storage chamber 101. The side wall of the air duct 114 has an inlet hole 1140 that communicates with the first liquid storage chamber 101. The atomizing core 12 is installed inside the air duct 114 and covers the inlet hole 1140 (i.e., the atomizing core 12 is connected to the first liquid storage chamber 101 through the inlet hole 1140). The connector 113 includes a pipe portion 1131 with an installation channel 11311 (illustratively, as shown in the figure). Figure 13 As shown, the pipe section 1131 is hollow and has a through-hole forming an installation channel 11311. The pipe section 1131 penetrates the base 112 along the thickness direction and forms a sealed fit with the base 112. A second liquid passage hole 11312 is provided on the side wall of the pipe section 1131. The second liquid passage hole 11312 is located in the first liquid storage cavity 101 and communicates with the first liquid storage cavity 101. Along the height direction of the outer shell section 111, there is a minimum vertical distance L between the hole wall of the second liquid passage hole 11312 and the bottom wall of the first liquid 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); the first liquid passage hole 241 of the sealing element 24 is connected to the liquid outlet hole 2210 of the liquid outlet 221 and the second liquid passage hole 11312 of the pipe section 1131 respectively.

[0094] In this embodiment, the above-described structural design facilitates the assembly of the atomizer 1. Specifically, when manufacturing the atomizer 1 of this embodiment, the atomizing core 12 is first inserted into the airway tube 114, ensuring that the outer wall of the atomizing core 12 covers the liquid inlet 1140 of the airway tube 114; then, the airway tube 114 containing the atomizing core 12 is inserted into the upper side of the base 112; subsequently, the connector 113 is installed on the lower side of the base 112, ensuring that the upper end of the pipe portion 1131 protrudes from the upper end face of the base 112; then, the base 112 containing the connector 113 and the airway tube 114 is inserted into the bottom of the outer shell portion 111, ensuring that the upper end of the airway tube 114 mates with the top of the outer shell portion 111; finally, the mouthpiece 13 is installed on the top of the outer shell portion 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 second liquid passage 11312 and the bottom wall of the first liquid storage chamber 101 to be not less than 1 mm, it is possible that during the process when the atomizing liquid in the first liquid storage chamber 101 of the atomizer 1 and the second liquid storage chamber 201 of the liquid storage chamber 2 are both consumed and a new liquid storage chamber 2 needs to be replaced, the small amount of atomizing liquid remaining in the first liquid storage chamber 101 is unlikely to leak to the outside through the second liquid passage 11312 and the installation channel 11311.

[0095] In this embodiment, it should be noted that the number of liquid outlet holes 2210, first liquid passage holes 241, and second liquid passage holes 11312 can be determined according to actual usage requirements, and this embodiment does not impose specific limitations on this. Optionally, two liquid outlet holes 2210, two first liquid passage holes 241, and two second liquid passage holes 11312 are each provided. The two liquid outlet holes 2210 are arranged relatively alternately, the two first liquid passage holes 241 are arranged relatively alternately, and the two second liquid passage holes 11312 are arranged relatively alternately. Each liquid outlet hole 2210, each first liquid passage hole 241, and each second liquid passage hole 11312 is connected in a one-to-one correspondence. This arrangement is beneficial for replenishing the atomizing liquid, allowing the atomizing liquid in the second liquid storage chamber 201 to be pumped into the first liquid storage chamber 101 more quickly.

[0096] Furthermore, in some optional embodiments of this application, the circumferential portion of the first housing 11 corresponding to the first liquid storage chamber 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 liquid storage chamber 101 at any time, enabling them to intuitively determine whether the atomizing liquid in the first liquid storage chamber 101 has been completely consumed and whether the first liquid storage chamber 101 is full of atomizing liquid during the process of replenishing the atomizer 1 with atomizing liquid through the liquid reservoir 2.

[0097] 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 the reference.
