Atomizers and electronic atomization devices

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411648330.1, filed on November 18, 2024, entitled "Atomizer and Electronic Atomizing Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of atomization technology, and in particular to the design of an atomizer and an electronic atomization device. Background Technology

[0004] An electronic atomizing device is a device that can atomize liquid preparations into an aerosol. In some exemplary prior art, an electronic atomizing device includes an atomizer, in which an atomizing component is disposed and a liquid matrix is ​​stored, the atomizing component being used to atomize the liquid matrix to produce an aerosol.

[0005] Existing electronic atomizing devices include product types that combine a main atomizer and a refill tank. The main atomizer has a first liquid reservoir, and the refill tank has a second liquid reservoir. The refill tank can be mounted on the main atomizer, thereby replenishing the liquid matrix to the main atomizer and increasing the liquid capacity of the electronic atomizing device.

[0006] Existing electronic atomizers that combine a main atomizer and a refill tank have the problem that the e-liquid in the refill tank cannot be quickly replenished to the main atomizer during initial use; or, although the e-liquid in the refill tank can be quickly replenished to the atomizer, excessive e-liquid supplied to the atomizer during vaping can cause liquid leakage, resulting in a mismatch between the liquid supply demand during initial use and during vaping.

[0007] Application content

[0008] This application provides an atomizer that enables the atomizing component and the container to rapidly transfer the liquid matrix from the container to the atomizing component when they are first connected, and to slowly transfer the liquid matrix from the container to the atomizing component during the inhalation process.

[0009] At least one embodiment of this application provides an atomizer, including:

[0010] The atomizing assembly includes a first liquid reservoir for storing a liquid matrix and an atomizing element for atomizing the liquid matrix to generate an aerosol.

[0011] The container has a second liquid storage chamber for storing a liquid matrix. The container can be connected to an atomizing assembly to replenish the liquid matrix to the atomizing assembly. When the container is connected to the atomizing assembly, a liquid guiding channel is established between the container and the atomizing assembly for conducting the liquid matrix in the second liquid storage chamber to the first liquid storage chamber, and at least one air guiding channel for guiding air in the first liquid storage chamber to the second liquid storage chamber.

[0012] The movable element is configured to be operable to move from a first position to a second position to close at least a portion of the gas channel, thereby regulating the rate at which the liquid matrix flows through the liquid channel.

[0013] In one embodiment, when the movable member is in the first position, the liquid guiding channel has a first liquid guiding velocity, and when the movable member is in the second position, the liquid guiding channel has a second liquid guiding velocity, the second liquid guiding velocity being less than the first liquid guiding velocity.

[0014] In one embodiment, the container is provided with an indicator mark for indicating that the remaining liquid in the second liquid storage chamber has reached a preset liquid volume, and the indicator mark is used to prompt the user to move the movable part from the first position to the second position.

[0015] In one embodiment, when the container is connected to the atomizing component, multiple air channels are established between the container and the atomizing component to guide air into the second liquid storage chamber. When the movable part is in the first position, all multiple air channels are open; when the movable part is in the second position, the movable part blocks at least one air channel.

[0016] In one embodiment, the first liquid storage chamber is filled with a liquid storage element having a microporous structure. The liquid storage element is used to absorb and retain the liquid matrix in the first liquid storage chamber. The gas guiding channel includes a first gas guiding channel, and the first gas guiding channel and the liquid guiding channel are shared.

[0017] In one embodiment, the liquid channel has an outlet, and a liquid reservoir covers the outlet to receive the liquid matrix from the liquid channel.

[0018] In one embodiment, a second capillary liquid guiding element is provided in the liquid guiding channel, and the second capillary liquid guiding element is in contact with the liquid storage element.

[0019] In one embodiment, the atomizer has a front side and a rear side along the thickness direction, and the air guide channel includes a second air guide channel and a third air guide channel spaced apart, the second air guide channel being adjacent to the front side of the atomizer and the third air guide channel being adjacent to the rear side of the atomizer.

[0020] In one embodiment, the movable member simultaneously opens the second and third air passages when in the first position, and simultaneously closes the second and third air passages when in the second position; and / or,

[0021] The liquid guiding channel is always open when the container and the atomizing component are connected.

[0022] In one embodiment, the liquid guiding channel is located between the second and third gas guiding channels along the thickness direction of the atomizer.

[0023] In one embodiment, the atomizing component has a first end and a second end disposed opposite to each other along its length, and a portion of a second air passage and / or a third air passage extends substantially from the first end to the second end.

[0024] In one embodiment, the second air guide channel and / or the third air guide channel includes a first section and a second section extending side by side. The first section has a first air inlet and a first air outlet, and the second section has a second air inlet and a second air outlet. The first air inlet is connected to a first liquid storage chamber, the first air outlet is used to connect to the second air inlet, and the second air outlet is used to connect to the second liquid storage chamber. When the movable member is in the first position, there is a gap between the movable member and both the first air outlet and the second air inlet for air to flow through. When the movable member is in the second position, the movable member blocks the first air outlet and / or the second air inlet.

[0025] In one embodiment, the atomizing assembly further includes a tubular portion with a partition wall extending longitudinally inside the tubular portion. The inner wall of the tubular portion and the partition wall respectively define at least a portion of a first section and a second section. A sealing member is provided on the movable member, which extends partially into the tubular portion and elastically abuts against the inner wall of the tubular portion. When the movable member is in the second position, the sealing member abuts against the end face of the partition wall, thereby blocking the first air outlet and the second air inlet.

[0026] In one embodiment, the atomizing assembly includes a main housing defining a first liquid reservoir, the main housing having an open end for aerosol to escape from the atomizing assembly, and a movable component including a cover assembly connected to the main housing and sealing the open end.

[0027] In one embodiment, the open end is provided with a receiving chamber through which the aerosol flows, the cover assembly is received in the receiving chamber and is provided with an air outlet for the aerosol to escape from the atomizing component, the cover assembly also includes a cover plate having an installation chamber and a sealing element installed in the installation chamber, the sealing element elastically abutting against the inner wall of the receiving chamber to seal the open end.

[0028] At least one embodiment of this application also provides an electronic atomizing device, comprising:

[0029] The outer casing has a receiving chamber;

[0030] The atomizer in the above embodiments is removably housed in a housing chamber;

[0031] Power supply unit, used to provide electrical energy to the atomizer.

[0032] In one embodiment, when the movable member is in a first position, it provides a stop to prevent the atomizer from entering the containment chamber, and when the movable member is in a second position, it releases the stop to allow the atomizer to enter the containment chamber.

[0033] The atomizer provided in the above embodiments, by incorporating a movable component, can partially close the air delivery channel when the component moves from the first position to the second position. This alters the rate at which the liquid matrix in the second storage chamber is transferred to the first storage chamber via the liquid delivery channel. In this way, when the container and atomizing assembly are initially connected, the container can transfer its liquid matrix to the atomizing assembly at a faster rate, reducing user waiting time and improving the user experience. Furthermore, when the liquid matrix stored in the atomizing assembly reaches saturation, moving the movable component from the first position to the second position reduces the liquid matrix transfer rate during aspiration, preventing leakage due to excessively rapid transfer during suction.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] The terms "first," "second," and "third" used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship or movement of the components in a specific orientation (as shown in the accompanying drawings).

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0050] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be intervening elements. When an element is referred to as being "connected to" another element, it can be directly connected to the other element, or there may be one or more intervening elements.

[0051] One embodiment of this application provides an electronic atomizing device 100, as shown in Figures 1 to 3. The electronic atomizing device 100 includes a housing 10, an atomizer 20, a power supply assembly 30, and a mouthpiece 40. The housing 10 includes a first housing 11 and a second housing 12 detachably connected to the first housing 11. The first housing 11 and the second housing 12 enclose a receiving chamber 13. The power supply assembly 30 is assembled onto the first housing 11 or the second housing 12. The atomizer 20 is removably housed in the receiving chamber 13. The power supply assembly 30 and the atomizer 20 are electrically connected to provide electrical energy to the atomizer 20, causing the atomizer 20 to atomize the liquid matrix stored inside it to generate an aerosol, which can be inhaled through the mouthpiece 40.

[0052] As shown in Figures 2 and 3, the atomizer 20 includes an atomizing component 21 and a container 22 detachably connected to the atomizing component 21. The atomizing component 21 has a first liquid storage chamber 211, and the container 22 defines a second liquid storage chamber 221. The first and second liquid storage chambers 211 and 221 are used to store atomizable liquid matrix. The atomizing component 21 also includes an atomizing element for atomizing the liquid matrix in the first liquid storage chamber 21 to generate an aerosol. When the container 22 is connected to the atomizing component 21, a liquid guiding channel is established between the container 22 and the atomizing component 21 to transfer the liquid matrix in the second liquid storage chamber 221 to the first liquid storage chamber 211, as shown by the liquid transfer path R1 in Figure 3. This increases the amount of liquid matrix stored in the atomizer 20, thereby reducing the frequency of user replacement of the atomizer 20 or the frequency of user injection of liquid matrix into the atomizer 20.

[0053] The liquid matrix can contain a liquid containing tobacco-based substances with volatile tobacco flavor components, or it can contain a liquid containing non-tobacco substances. The liquid matrix can contain water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances can include areca nut extract, menthol, peppermint, spearmint oil, various fruit flavorings, etc., but are not limited to these. Flavorings can contain ingredients that can provide users with various fragrances or flavors. Based on the different properties of the liquid matrix, the electronic atomizing device 1000 can be used in different fields, such as medical and electronic cigarettes.

[0054] When the liquid matrix in the second liquid storage chamber 221 of the container 22 is consumed, the user can disassemble the first housing 11 and the second housing 12, then remove the container 22 from the atomizer 20 and replace it with a new container 22. This allows the power supply component 30 and the atomizing element of the electronic atomizing device 100 to be recycled, reducing the user's operating costs.

[0055] When a user needs to change to a new vaping flavor, the atomizer 20 can be completely removed from the electronic atomizing device 100, and then a new atomizer 20 can be installed into the electronic atomizing device 100. The new atomizer 20 can store liquid matrix with different components and atomizing elements that can provide different power. Thus, by changing the atomizer 20, different vaping flavors can be obtained.

[0056] As shown in Figure 3, a liquid storage component 212 is provided in the first liquid storage chamber 211. The liquid storage component 212 is used to absorb and retain the liquid matrix in the first liquid storage chamber 211. An axially extending through hole (not shown) is provided in the liquid storage component 212. An atomizing element is provided in the through hole. The atomizing element includes a first capillary liquid guiding component 213 and a heating element 214 combined with the first capillary liquid guiding component 213. The first capillary liquid guiding component 213 and the liquid storage component 212 are in contact with each other. Thus, the liquid storage component 212 can further transfer the liquid matrix it stores to the first capillary liquid guiding component 213. The heating element 214 on the first capillary liquid guiding component 213 can heat and atomize the liquid matrix to generate an aerosol.

[0057] Both the first capillary liquid guiding element 213 and the liquid storage element 212 are made of porous materials, such as cotton fibers, non-woven fabrics, fiberglass ropes, porous glass, or porous ceramics. This allows the first capillary liquid guiding element 213 and the liquid storage element 212 to absorb or conduct the liquid matrix through their internal microporous structure or pores. Correspondingly, the heating element 214 can be bonded to the first capillary liquid guiding element 213 or wound around it by means of printing, deposition, sintering, or physical assembly.

[0058] Please refer to Figure 3. The atomizing assembly 21 also includes an air outlet 215 and an air guide tube 216. The air outlet 215 allows the aerosol generated after atomization to escape from the atomizing assembly 21. One end of the air guide tube 216 is connected to the air outlet 215, and the other end is inserted into the through hole to communicate with the atomizing element. Thus, the aerosol generated after atomization by the atomizing element can enter the air guide tube 216 and be transported to the air outlet 215 by the air guide tube 216. The mouthpiece 40 is detachably connected to the air outlet 215. The aerosol flowing into the air outlet 215 further enters the mouthpiece 40, so that the user can inhale the aerosol when inhaling through the mouthpiece 40, as shown by the aerosol flow path R2 in Figure 3.

[0059] The power supply assembly 30 includes a battery cell 31 and a main board 32. The main board 32 is equipped with a controller for the electronic atomizing device 100. The battery cell 31 and the heating element 214 are both electrically connected to the controller, so that the controller can control the battery cell 31 to provide the electrical energy required for heating and atomization to the heating element 214.

[0060] In other embodiments, the atomizing component may also include an ultrasonic atomizing component, which atomizes the liquid matrix into an aerosol through high-frequency vibration. The atomizing component may also be other components capable of forming a mist from the liquid matrix. This application does not impose specific limitations on the type of atomizing component.

[0061] The atomizing assembly 21 also includes a movable element, and when the container 22 is connected to the atomizing assembly 21, at least one air channel is established between the container 22 and the atomizing assembly 21 for guiding air in the first liquid storage chamber 211 to the second liquid storage chamber 221. The movable element is configured to be operable to move from a first position to a second position to close at least a portion of the air channel, thereby regulating the rate at which the liquid matrix flows through the liquid channel R1.

[0062] For example, when the container 22 is connected to the atomizing component 21, three air channels are established between the container 22 and the atomizing component 21. When the moving part is in the first position, all three air channels are in the conductive state. At this time, the air in the first liquid storage chamber 211 can flow to the second liquid storage chamber 221 through these three air channels, thereby quickly balancing the air pressure in the second liquid storage chamber 221. The liquid matrix in the second liquid storage chamber 221 can then flow to the first liquid storage chamber 211 at a relatively fast liquid guiding rate through the liquid guiding channel R1.

[0063] When the liquid matrix in the first liquid storage chamber 211 reaches saturation, the user-operable movable part moves from the first position to the second position. At this time, the movable part closes at least part of the liquid guiding channel, which causes the gas pressure balance speed in the second liquid storage chamber 221 to decrease, and consequently the liquid guiding rate of the liquid matrix in the second liquid storage chamber 221 also decreases accordingly.

[0064] The atomizer 20 provided in this embodiment can set the initial position of the movable part on the atomizing component 21 to the first position. Therefore, when the container 22 is first connected to the atomizing component 21, the air passage between the container 22 and the atomizing component 21 is fully open. At this time, the liquid matrix stored in the container 22 can quickly flow into the atomizing component 21 through the liquid passage R1, thereby achieving rapid automatic liquid injection, reducing user waiting time, and effectively improving the user experience. When the liquid matrix received in the first liquid storage chamber 211 reaches saturation, the user can start using the atomizer 20 for inhalation. Simultaneously, the user can operate the movable part to move from the first position to the second position to close at least a portion of the air passage, thereby reducing the liquid matrix inhalation rate during inhalation and preventing leakage of the liquid matrix due to excessively fast inhalation.

[0065] In some embodiments, the second liquid storage chamber 22 is provided with a preset liquid volume. When the liquid volume of the remaining liquid matrix in the second liquid storage chamber 22 is greater than the preset liquid volume, the movable member is held in the first position. When the liquid volume of the remaining liquid matrix in the second liquid storage chamber 22 is less than the preset liquid volume, the movable member is held in the second position, and at this time the first liquid guiding speed is greater than the second liquid guiding speed.

[0066] For example, to prevent leakage of the electronic atomizing device 100 during transportation or storage, the first liquid storage chamber 211 is not filled with liquid matrix initially. After the user purchases the electronic atomizing device 100, the user can first disassemble the first housing 11 and the second housing 12, and then connect the matching container 22 and the atomizing component 21. At this time, the moving parts are kept in the first position, so that the air guiding channels are all in the conducting state. The liquid matrix in the second liquid storage chamber 221 begins to be conducted to the first liquid storage chamber 211 at a relatively fast first liquid guiding speed through the liquid guiding channel R1, so that the first liquid storage chamber 211 quickly reaches the saturation state. At this time, the amount of liquid matrix remaining in the second liquid storage chamber 221 reaches the preset amount.

[0067] When the liquid matrix received by the first liquid storage chamber 211 reaches saturation, the user can operate the movable part to move from the first position to the second position, so that the movable part blocks and closes at least one air guide channel. This allows the liquid matrix in the second liquid storage chamber 221 to be conducted to the first liquid storage chamber 211 through the liquid guide channel R1 at a slower second liquid guide speed. When the user aspirates, the liquid matrix in the first liquid storage chamber 211 is gradually consumed. At this time, the liquid matrix can be slowly replenished to the first liquid storage chamber 211 through the second liquid guide speed. If the liquid guide speed is too fast, it will easily cause the liquid matrix in the first liquid storage chamber 211 to leak, affecting the user's experience.

[0068] Alternatively, in some embodiments, when the first liquid storage chamber 211 has been pre-filled with liquid matrix, to prevent excessively fast liquid guiding speed when the container 22 and atomizing component 21 are connected, which could cause liquid leakage from the first liquid storage chamber 221, the movable component remains in the first position so that the liquid guiding channel R1 conducts the liquid matrix in the second liquid storage chamber 221 to the first liquid storage chamber 211 at a slower first liquid guiding speed. When the liquid matrix in both the first and second liquid storage chambers 211 is depleted, the user replaces the container 22 and connects the new container 22 to the atomizing component 21. At this time, the operable movable component moves from the first position to the second position, so that the liquid matrix in the second liquid storage chamber 221 can be conducted to the first liquid storage chamber 211 at a faster second liquid guiding speed, allowing the first liquid storage chamber 211 to reach saturation more quickly. In this case, the first liquid guiding speed is less than the second liquid guiding speed.

[0069] In some embodiments, as shown in FIG4, the atomizing component 21 includes a main housing 217, a first liquid storage chamber 211 disposed in the main housing 217, the atomizing component 21 further includes an open end 218 for aerosol to escape from the atomizing component 21, and the movable part includes a cover assembly 219 connected to the main housing 217 and sealing the open end 218.

[0070] Specifically, as shown in Figures 5 and 6, the cover assembly 219 includes a cover 2191 having a first surface 2192 and a second surface 2193 disposed opposite to each other, and a sidewall 2194 extending from the second surface 2193. The second surface 2193 and the sidewall 2194 define an installation chamber 2195. The cover 219 also includes a seal 210 installed in the installation chamber 2195. The open end 218 is provided with a receiving chamber 2181 through which aerosol flows. The cover assembly 219 is at least partially received in the receiving chamber 2181. The seal 210 is made of any one of soft rubber materials such as silicone, rubber, or latex, and thus the seal 210 can elastically abut against the inner wall of the receiving chamber 2181 to seal the open end 218.

[0071] Furthermore, in some implementations, as shown in Figures 5 and 6, a latching part 21941 is provided on the side wall 2194, and a first latching groove 21811 and a second latching groove 21812 are provided on the inner wall of the receiving chamber 2181. The first latching groove 21811 and the second latching groove 21812 are spaced apart along the moving direction of the cover assembly 219. When the container 22 and the atomizing assembly 21 are initially connected, the latching part 21941 engages with the first latching groove 21811, thereby connecting the cover assembly 219 and the main housing 217. At this time, the cover assembly 219 is held in the first position, as shown in Figure 8.

[0072] When the remaining liquid matrix in the second liquid storage chamber 221 reaches the preset liquid volume, the user presses the cover assembly 219, causing the latch 21941 to move from the first latch 21811 to the second latch 21812 and latch together with the second latch 21812. At this time, the cover assembly 219 remains in the second position, as shown in Figure 9.

[0073] It is easy to understand that the latch part 21941 can also be provided on the inner wall of the receiving compartment 218, while the first latch 21811 and the second latch 21812 are provided on the side wall 2194 of the cover 2191.

[0074] In some embodiments, as shown in FIG2, the container 22 is made of a transparent material, and an indicator mark 222 that can be observed by the user is provided on the surface of the container 22. When the container 22 is connected to the atomizing component 21, the liquid matrix in the second liquid storage chamber 221 is conducted to the first liquid storage chamber 211 at a relatively fast first liquid guiding speed. When the liquid level of the remaining liquid matrix in the second liquid storage chamber 221 is at the indicator mark 222, it indicates that the liquid volume of the remaining liquid matrix in the second liquid storage chamber 221 has reached the preset liquid volume, that is, the liquid volume of the liquid matrix received in the first liquid storage chamber 211 has reached saturation. At this time, the user can move the movable part from the first position to the second position so that the liquid guiding speed is switched from the faster first liquid guiding speed to the slower second liquid guiding speed.

[0075] In some embodiments, as shown in Figures 7, 8 and 10, the air guiding channel includes a first air guiding channel shared with the liquid guiding channel R1, and a second air guiding channel R3 and a third air guiding channel R4 that can be closed or opened by a movable component. By sharing the first air guiding channel and the liquid guiding channel R1, the complexity of the air guiding channel design can be reduced.

[0076] When no liquid matrix is ​​pre-injected into the first liquid storage chamber 211, the liquid storage component 212 does not absorb the liquid matrix, thus the microporous structure in the liquid storage component 212 is not occupied by the liquid matrix, and air in the first liquid storage chamber 211 can enter the microporous structure of the liquid storage component 212. When the container 22 and the atomizing component 21 are connected, the movable component remains in the first position, thereby opening the second air guiding channel R3 and the third air guiding channel R4. Air in the first liquid storage chamber 211 can then enter the second liquid storage chamber 221 through the second air guiding channel R3 and the third air guiding channel R4. At the same time, air in the first liquid storage chamber 211 can also enter the second liquid storage chamber 211 through the first air guiding channel (that is, the liquid guiding channel R1). At this time, the liquid matrix in the second liquid storage chamber 221 can be conducted to the first liquid storage chamber 211 at a relatively fast first liquid guiding speed through the liquid guiding channel R1.

[0077] When the liquid matrix received in the first liquid storage chamber 211 reaches saturation, the movable component is moved from the first position to the second position by the user. The movable component closes the second air guide channel R3 and the third air guide channel R4, preventing air from the first liquid storage chamber 211 from entering the second liquid storage chamber 221 through the second air guide channel R3 and the third air guide channel R4. At the same time, the liquid matrix absorbed in the liquid storage component 212 also reaches saturation, preventing air from the first liquid storage chamber 211 from entering the liquid storage component 212, and temporarily preventing air from the first liquid storage chamber 211 from entering the second liquid storage chamber 221 through the first air guide channel.

[0078] When the user uses the electronic atomizing device 100 for inhalation, the liquid matrix absorbed and held in the liquid storage component 212 is partially consumed. The air in the first liquid storage chamber 211 can re-enter the liquid storage component 212 and then enter the second liquid storage chamber 221 again through the first air guide channel. At this time, since the moving part is still in the second position, the second air guide channel R3 and the third air guide channel R4 are still blocked, thereby reducing the amount of air entering the second liquid storage chamber 221. As a result, the liquid guide channel R1 can conduct the liquid in the second liquid storage chamber 221 to the first liquid storage chamber 211 at a slower second liquid guide speed. In other words, during the user's inhalation process, the liquid matrix in the second liquid storage chamber 221 can be slowly conducted to the first liquid storage chamber 211, avoiding leakage of the liquid matrix due to excessively fast conduction speed during the inhalation process.

[0079] Therefore, as can be seen from the above, the liquid guiding channel R1 is always open when the container 22 and the atomizing component 21 are connected. Thus, during the suction process, although the second air guiding channel R3 and the third air guiding channel R4 are blocked and closed by the moving parts, the air in the first liquid storage chamber 211 can still enter the second liquid storage chamber 221 through the liquid guiding channel R1, so that during the suction process, the liquid matrix in the second liquid storage chamber 221 can be conducted to the first liquid storage chamber 211 at a slower second liquid guiding speed.

[0080] In some embodiments, as shown in FIG7, a second capillary liquid guiding element 231 is provided in the liquid guiding channel R1. The liquid storage element 212 is in contact with the second capillary liquid guiding element 231. The second capillary liquid guiding element 231 is also made of a porous material, which can be any one of cotton fiber, non-woven fabric, fiberglass rope, porous glass, or porous ceramic. By providing the second capillary liquid guiding element 231, the traction force on the liquid matrix can be increased to slow down the conduction rate of the liquid matrix and avoid leakage caused by excessively fast conduction speed of the liquid matrix.

[0081] Furthermore, in some embodiments, as shown in FIG7, the liquid guiding channel R1 has a liquid outlet 232, which is connected to the first liquid storage chamber 211. The liquid matrix flowing out of the liquid outlet 232 can enter the first liquid storage chamber 211. The liquid storage component 212 covers the liquid outlet 232 so that air in the microporous structure of the liquid storage component 212 can quickly enter the liquid guiding channel R1, and then enter the second liquid storage chamber 221 through the liquid guiding channel R1. Also, when the liquid matrix absorbed in the liquid storage component 212 reaches saturation, the liquid storage component 212 can prevent air in the first liquid storage chamber 211 from continuing to enter the liquid guiding channel R1 through the liquid outlet 232.

[0082] In some embodiments, as shown in FIG8, the second air guide channel R2 and / or the third air guide channel R4 include a first section 251 and a second section 252 extending side by side. The first section 251 has a first air inlet 2511 and a first air outlet 2512, and the second section 252 has a second air inlet 2521 and a second air outlet 2522. The first air inlet 2511 is connected to the first liquid storage chamber 211. When the container 22 is connected to the atomizing component 21, the second air outlet 252 is connected to the second liquid storage chamber 221.

[0083] When the cover assembly 219, which is one of the movable parts, is in the first position, there is a gap 2513 between the cover assembly 219 and the first air outlet 2512 and the second air inlet 2521 for air to flow through. At this time, the air in the first section 251 can flow into the second section 252. The second air guide channel R2 and / or the third air guide channel R4 are in the conducting state. The air in the first liquid storage chamber 211 can enter the second liquid storage chamber 221 through the second air guide channel R3 and / or the third air guide channel R4, as shown in Figure 8.

[0084] When the cover assembly 219 is in the second position, the cover assembly 219 blocks the first air outlet 2512 and the second air inlet 2521, so that the air in the first section 251 cannot enter the second section 252, the second air guide channel R3 and / or the third air guide channel R4 are in a closed state, and the air in the first liquid storage chamber 211 cannot enter the second liquid storage chamber 221 through the second air guide channel R4.

[0085] Specifically, as shown in Figures 10 and 12, the main housing 217 forms a tubular portion 2171, with a partition wall 2172 extending longitudinally inside the tubular portion 2171. The inner wall of the tubular portion 2171 and the partition wall 2171 respectively define at least a portion of the first section 251 and the second section 252. The sealing element 210 on the cover assembly 219 extends into the tubular portion 2171 and elastically abuts against the inner wall of the tubular portion 2171. Thus, when the cover assembly 219 moves to the second position, the sealing element 210 abuts against the end face of the partition wall 2172, thereby sealing the first air outlet 2512 and the second air inlet 2521.

[0086] Furthermore, in some embodiments, as shown in FIG8, the atomizer 20 has a first end 203 and a second end 204 disposed opposite to each other along its length direction, and a second section 252 extends substantially from the first end 203 to the second end 204, that is, a portion of the air passage of the second air passage R3 and / or the third air passage R4 is located above the first liquid storage chamber 211, thereby preventing leakage of the liquid matrix in the first liquid storage chamber 211 from the second air passage R3 and / or the third air passage R4.

[0087] It is easy to understand that in some embodiments, when the cover assembly 219 is in the second position, the cover assembly 219 can also block the first air outlet 2512 or block the second air inlet 2521, so that the air in the first section 251 cannot enter the second section 252.

[0088] In some embodiments, as shown in FIG10, the atomizer 20 has a front side 201 and a rear side 202 along the thickness direction, which is the X direction in FIG11. The second air guide channel R3 and the third air guide channel R4 are arranged at intervals, with the second air guide channel R3 located adjacent to the front side 201 of the atomizer 20 and the third air guide channel R4 located adjacent to the rear side 202 of the atomizer 20. Thus, when the container 22 and the atomizing assembly 21 are connected, the movable part is in the first position, both the second air guide channel R3 and the third air guide channel R4 are in the conducting state, and when the atomizer 20 is in the horizontal position as shown in FIG11, the liquid matrix in the second liquid storage chamber 221 is at the bottom of the second liquid storage chamber 221 under the action of gravity. The air in the first liquid storage chamber 211 will enter the second liquid storage chamber 221 through the second air guide channel R3, while the third air guide channel R4 will act as another liquid guide channel to conduct the liquid matrix in the second liquid storage chamber 221 to the first liquid storage chamber 211.

[0089] When the liquid matrix in the first liquid storage chamber 211 reaches saturation, the movable part moves from the first position to the second position. At this time, the second air guide channel R3 and the third air guide channel R4 are blocked and closed by the movable part, while the liquid guide channel R1 is in a conductive state. The air in the first liquid storage chamber 211 and the liquid matrix in the second liquid storage chamber 221 can only be conducted through the liquid guide channel R1.

[0090] Further, in some embodiments, referring to FIG10, along the thickness direction of the atomizer 20, the liquid guiding channel R1 (i.e., the first air guiding channel) is located between the second air guiding channel R3 and the third air guiding channel R4, so that the first air guiding channel, the second air guiding channel R3, and the second air guiding channel R3 have a confluence point R134, which then connects to the second liquid storage chamber 221, thereby reducing the complexity of the air guiding channel structure design. In some embodiments, as shown in FIG2, when the cover assembly 219, which is one of the movable parts, is in the first position, the cover assembly 210 protrudes from the main housing 217, which causes the cover assembly 210 to block the atomizer 20 from being housed in the housing chamber 13. When the cover assembly 219 moves to the second position, the atomizer 20 can be housed in the receiving chamber 13. In other words, when the cover assembly 219 moves to the second position, it releases its obstruction of the atomizer 20, allowing it to be housed in the receiving chamber 13. This method serves as a reminder to the user that no liquid medium has been injected into the atomizing component 21; that is, the liquid matrix in the container 22 has not yet been introduced into the atomizing component 21, effectively preventing dry burning of the atomizing component 21.
