[0048] An electronic atomization device 100 is provided in an embodiment of the application, as shown in Figure 1 and Figure 2 The electronic atomization 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 to the first housing 11 or the second housing 12. The atomizer 20 is removably received in the receiving chamber 13. The power supply assembly 30 and the atomizer 20 are electrically connected to provide electric power to the atomizer 20. The atomizer 20 atomizes liquid substrate stored therein to generate aerosol, which can be inhaled through the mouthpiece 40.
[0049] As shown in Figure 2 and Figure 3 The atomizer 20 includes an atomization assembly 21 and a container 22 detachably connected to the atomization assembly 21. The atomization assembly 21 is provided with a first liquid storage cavity 211. The container 22 defines a second liquid storage cavity 221. The first liquid storage cavity 211 and the second liquid storage cavity 221 are used to store atomizable liquid substrate. The atomization assembly 21 further includes an atomization element for atomizing the liquid substrate in the first liquid storage cavity 211 to generate aerosol. When the container 22 is connected to the atomization assembly 21, a liquid transfer passage is established between the container 22 and the atomization assembly 21 to transfer the liquid substrate in the second liquid storage cavity 221 to the first liquid storage cavity 211, as shown by a liquid transfer route R1 in Figure 3 to increase the liquid storage capacity of the atomizer 20, thereby reducing the frequency of replacing the atomizer 20 by a user or reducing the frequency of injecting liquid substrate into the atomizer 20 by a user.
[0050] The liquid matrix may contain a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it may contain a liquid containing non-tobacco substances. The liquid matrix may contain water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include, but are not limited to, menthol, peppermint oil, spearmint oil, and various fruit flavoring components. Flavorings may contain ingredients that can provide the user with various fragrances or flavors.
[0051] 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.
[0052] 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.
[0053] like Figure 3 As shown, 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. The liquid storage component 212 can further transfer the liquid matrix stored therein 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.
[0054] 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.
[0055] Please continue reading. Figure 3The atomization assembly 21 further comprises an air outlet hole 215 and an air guide pipe 216. The air outlet hole 215 is configured to allow the aerosol generated by the atomization assembly 21 to escape from the atomization assembly 21. The air guide pipe 216 is connected to the air outlet hole 215 at one end and is inserted into the through hole to communicate with the atomization element at the other end. Thus, the aerosol generated by the atomization element can enter the air guide pipe 216 and be transmitted to the air outlet hole 215 by the air guide pipe 216. The mouthpiece 40 is detachably connected to the air outlet hole 215. The aerosol flowing into the air outlet hole 215 further flows into the mouthpiece 40. Thus, the user can inhale the aerosol when sucking the mouthpiece 40, as shown by the flow path R2 of the aerosol in FIG. 4. Figure 3
[0056] The power supply assembly 30 comprises an electric core 31 and a main board 32. The main board 32 is provided with a controller of the electronic atomization device 100. The electric core 31 and the heating element 214 are electrically connected to the controller. Thus, the controller can control the electric core 31 to provide the heating element 214 with the electric energy required for heating and atomization.
[0057] In other embodiments, the atomization assembly can also comprise an ultrasonic atomization assembly. The ultrasonic atomization assembly atomizes the liquid substrate to form the aerosol by high-frequency vibration. The atomization assembly can also be other assemblies capable of atomizing the liquid substrate to form the aerosol. The type of the atomization assembly is not limited in the present application.
[0058] The atomization assembly 21 further comprises a movable element. When the container 22 is connected to the atomization assembly 21, at least one air guide channel for guiding the air in the first liquid storage cavity 211 to the second liquid storage cavity 221 is established between the container 22 and the atomization assembly 21. 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 guide channel, thereby adjusting the flow rate of the liquid substrate flowing through the liquid guide channel R1.
[0059] For example, when the container 22 is connected to the atomization assembly 21, three air guide channels are established between the container 22 and the atomization assembly 21. When the movable element is in the first position, the three air guide channels are in an open state. At this time, the air in the first liquid storage cavity 211 can flow to the second liquid storage cavity 221 through the three air guide channels, thereby quickly balancing the air pressure in the second liquid storage cavity 221. The liquid substrate in the second liquid storage cavity 221 can flow to the first liquid storage cavity 211 at a relatively high flow rate through the liquid guide channel R1.
[0060] When the liquid substrate in the first liquid storage cavity 211 reaches saturation, the user can operate the movable element to move from the first position to the second position. At this time, the movable element closes at least a portion of the air guide channel, which reduces the air pressure balancing speed in the second liquid storage cavity 221, thereby reducing the flow rate of the liquid substrate in the second liquid storage cavity 221.
[0061] The atomizer 20 provided by the embodiment can set the initial position of the movable element on the atomization assembly 21 at the first position, so that when the container 22 is first connected with the atomization assembly 21, the air guiding passages between the container 22 and the atomization assembly 21 are all in the open state, at this time, the liquid substrate stored in the container 22 can flow to the atomization assembly 21 through the liquid guiding passage R1 quickly, so as to achieve quick automatic liquid injection, reduce the waiting time of the user, and effectively improve the use experience of the user. When the liquid substrate received in the first liquid storage cavity 211 reaches saturation, the user can start to use the atomizer 20 for suction, and at the same time, the user can operate the movable element to move from the first position to the second position to close at least part of the air guiding passages, thereby reducing the liquid guiding speed of the liquid substrate during the suction process, and avoiding the leakage of the liquid substrate due to the too fast liquid guiding speed during the suction process.
[0062] In some embodiments, the second liquid storage cavity 22 is provided with a preset liquid amount, when the liquid amount of the liquid substrate remaining in the second liquid storage cavity 22 is greater than the preset liquid amount, the movable element remains at the first position, and when the liquid amount of the liquid substrate remaining in the second liquid storage cavity 22 is less than the preset liquid amount, the movable element remains at the second position, and at this time, the first liquid guiding speed is greater than the second liquid guiding speed.
[0063] For example, in order to avoid the electronic atomization device 100 from leaking liquid during transportation or storage, the first liquid storage cavity 211 is not filled with liquid substrate at first, after the user purchases the electronic atomization device 100, the user can first disassemble the first shell 11 and the second shell 12, and then connect the matched container 22 and the atomization assembly 21, at this time, the movable element is kept at the first position, so that the air guiding passages are all in the open state, the liquid substrate in the second liquid storage cavity 221 starts to conduct to the first liquid storage cavity 211 through the liquid guiding passage R1 at a faster first liquid guiding speed, so that the first liquid storage cavity 211 quickly reaches the saturation state, at this time, the liquid amount of the liquid substrate remaining in the second liquid storage cavity 221 reaches the preset liquid amount.
[0064] When the liquid amount of the liquid substrate received in the first liquid storage cavity 211 reaches the saturation state, the user can operate the movable element to move from the first position to the second position, so that the movable element blocks to close at least one air guiding passage, thereby enabling the liquid substrate in the second liquid storage cavity 221 to conduct to the first liquid storage cavity 211 through the liquid guiding passage R1 at a slower second liquid guiding speed, when the user sucks, the liquid substrate in the first liquid storage cavity 211 is gradually consumed, at this time, the liquid substrate can be slowly supplemented to the first liquid storage cavity 211 through the second liquid guiding speed, if the liquid guiding speed is too fast, it will easily cause the liquid substrate in the first liquid storage cavity 211 to leak, affecting the use experience of the user.
[0065] Alternatively, in some embodiments, when the liquid substrate has been pre-injected into the first liquid storage cavity 211, in order to avoid the liquid being conducted too fast from the second liquid storage cavity 221 to the first liquid storage cavity 211 when the container 22 and the atomization assembly 21 are connected, causing the liquid in the first liquid storage cavity 211 to leak out, the movable member is kept at the first position to make the liquid substrate in the second liquid storage cavity 221 be conducted to the first liquid storage cavity 211 at a first liquid-conducting speed which is slower. When the liquid substrate in both the first liquid storage cavity 211 and the second liquid storage cavity 221 is consumed, the user replaces a new container 22 and connects the new container 22 and the atomization assembly 21, at this time, the movable member is operated to move from the first position to the second position, so that the liquid substrate in the second liquid storage cavity 221 can be conducted to the first liquid storage cavity 211 at a second liquid-conducting speed which is faster, so that the first liquid storage cavity 211 reaches saturation faster, at this time, the first liquid-conducting speed is smaller than the second liquid-conducting speed.
[0066] In some embodiments, as shown in Figure 4 , the atomization assembly 21 comprises a main housing 217, the first liquid storage cavity 211 is arranged in the main housing 217, the atomization assembly 21 further comprises an open end 218 for the aerosol to escape from the atomization assembly 21, and the movable member comprises a cover assembly 219 connected with the main housing 217 and sealing the open end 218.
[0067] Specifically, as shown in Figure 5 and Figure 6 , the cover assembly 219 comprises a cover 2191, the cover 2191 has a first surface 2192 and a second surface 2193 arranged oppositely, and a side wall 2194 extending from the second surface 2193, the second surface 2193 and the side wall 2194 define a mounting cavity 2195. The cover 219 further comprises a sealing member 210 arranged in the mounting cavity 2195, the open end 218 is provided with a receiving cavity 2181 for the aerosol to flow through, and the cover assembly 219 is at least partially arranged in the receiving cavity 2181, the sealing member 210 is made of any one of soft rubber, silicone rubber or latex, so that the sealing member 210 can elastically abut against the inner wall of the receiving cavity 2181 to seal the open end 218.
[0068] In addition, in some embodiments, as shown in Figure 5 and Figure 6 , the side wall 2194 is provided with a clamping portion 21941, the inner wall of the receiving cavity 2181 is provided with a first clamping groove 21811 and a second clamping groove 21812, the first clamping groove 21811 and the second clamping groove 21812 are arranged at intervals along the moving direction of the cover assembly 219, when the container 22 and the atomization assembly 21 are just connected, the clamping portion 21941 is clamped in the first clamping groove 21811, so that the cover assembly 219 and the main housing 217 are connected with each other, at this time, the cover assembly 219 is kept at the first position, as shown in Figure 8 .
[0069] When the liquid amount of the liquid substrate in the second liquid storage cavity 221 reaches the preset liquid amount, the user presses the cover assembly 219, so that the buckle part 21941 moves from the first clamping groove 21811 to the second clamping groove 21812 and is clamped and connected with the second clamping groove 21812, at this time, the cover assembly 219 is kept in the second position, as shown in Figure 9 .
[0070] It is easy to understand that the buckle part 21941 can also be arranged on the inner wall of the storage bin 218, and the first clamping groove 21811 and the second clamping groove 21812 are arranged on the side wall 2194 of the cover 2191.
[0071] Further, in some embodiments, as shown in Figure 2 , the container 22 is made of transparent material, and the surface of the container 22 is provided with an indication mark 222 that can be observed by the user, when the container 22 is connected with the atomization assembly 21, the liquid substrate in the second liquid storage cavity 221 is conducted to the first liquid storage cavity 211 at a faster first liquid conducting speed, when the liquid level of the liquid substrate in the second liquid storage cavity 221 is located at the indication mark 222, it indicates that the liquid amount of the liquid substrate in the second liquid storage cavity 221 has reached the preset liquid amount, that is, the liquid amount of the liquid substrate received in the first liquid storage cavity 211 reaches saturation, at this time, the user can move the movable part from the first position to the second position, so as to switch the liquid conducting speed from the faster first liquid conducting speed to the slower second liquid conducting speed.
[0072] In some embodiments, as shown in Figure 7 and Figure 8 , the air guide channel includes a first air guide channel shared with the liquid guide channel R1, and a second air guide channel R3 and a third air guide channel R4 that can be closed or opened by the movable part, by sharing the first air guide channel and the liquid guide channel R1, the complexity of the design of the air guide channel can be reduced.
[0073] When there is no pre-injected liquid substrate in the first liquid storage cavity 211, the liquid substrate is not absorbed in the liquid storage part 212, so that the microporous structure in the liquid storage part 212 is not occupied by the liquid substrate, and the air in the first liquid storage cavity 211 can enter the microporous structure of the liquid storage part 212. When the container 22 and the atomization assembly 21 are connected, the movable part is kept in the first position to open the second air guide channel R3 and the third air guide channel R4, so that the air in the first liquid storage cavity 211 can enter the second liquid storage cavity 221 through the second air guide channel R3 and the third air guide channel R4, and the air in the first liquid storage cavity 211 can also enter the second liquid storage cavity 211 through the first air guide channel (that is, the liquid guide channel R1), at this time, the liquid substrate in the second liquid storage cavity 221 can be conducted to the first liquid storage cavity 211 at a faster first liquid conducting speed through the liquid guide channel R1.
[0074] When the liquid substrate received in the first liquid storage cavity 211 reaches saturation, at which time the user operates the movable member from the first position to the second position, the movable member closes the second air guide passage R3 and the third air guide passage R4, and the air in the first liquid storage cavity 211 cannot enter the second liquid storage cavity 221 through the second air guide passage R3 and the third air guide passage R4. At the same time, the liquid substrate absorbed in the liquid storage member 212 also reaches saturation, and the air in the first liquid storage cavity 211 cannot enter the liquid storage member 212 any more, and the air in the first liquid storage cavity 211 cannot temporarily enter the second liquid storage cavity 221 through the first air guide passage.
[0075] When the user uses the electronic atomization device 100 for suction, the liquid substrate absorbed and retained in the liquid storage member 212 is partially consumed, the air in the first liquid storage cavity 211 can again enter the liquid storage member 212 and again enter the second liquid storage cavity 221 through the first air guide passage, at which time the second air guide passage R3 and the third air guide passage R4 are still blocked due to the movable member still remaining in the second position, thereby reducing the amount of air entering the second liquid storage cavity 221, and further allowing the liquid guide passage R1 to conduct the liquid in the second liquid storage cavity 221 to the first liquid storage cavity 211 at a second liquid conducting speed that is slower. That is, during the user's suction process, the liquid substrate in the second liquid storage cavity 221 can be slowly conducted to the first liquid storage cavity 211, avoiding leakage due to too fast conducting speed of the liquid substrate during the suction process.
[0076] Therefore, from the above content, it can be known that the liquid guide passage R1 is always conductive when the container 22 and the atomization assembly 21 are in the connected state, and further, during the suction process, although the second air guide passage R3 and the third air guide passage R4 are closed by the movable member, the air in the first liquid storage cavity 211 can still enter the second liquid storage cavity 221 through the liquid guide passage R1, so that the liquid substrate in the second liquid storage cavity 221 can be conducted to the first liquid storage cavity 211 at a second liquid conducting speed that is slower during the suction process.
[0077] In some embodiments, as shown in Figure 7 The liquid guide passage R1 is provided with a second capillary liquid guide member 231, the liquid storage member 212 and the second capillary liquid guide member 231 are in contact with each other, and the second capillary liquid guide member 231 is also made of a porous material, which can be any one of cotton fiber, non-woven fabric, glass fiber rope, porous glass, or porous ceramic. By providing the second capillary liquid guide member 231, the traction force on the liquid substrate can be increased to slow down the conducting speed of the liquid substrate and avoid leakage due to too fast conducting speed of the liquid substrate.
[0078] In addition, in some embodiments, as shown in Figure 7As shown, the liquid guide channel R1 has a liquid outlet 232 which is communicated to the first liquid storage cavity 211, and the liquid matrix flowing out of the liquid outlet 232 can enter into the first liquid storage cavity 211. The liquid storage member 212 covers the liquid outlet 232, so that the air in the microporous structure of the liquid storage member 212 can quickly enter into the liquid guide channel R1, and then enter into the second liquid storage cavity 221 through the liquid guide channel R1. In addition, when the liquid storage member 212 is saturated with the liquid matrix, the liquid storage member 212 can block the air in the first liquid storage cavity 211 from continuously entering into the liquid guide channel R1 through the liquid outlet 232.
[0079] In some embodiments, as shown in Figure 8 As shown, the second air guide channel R2 and / or the third air guide channel R4 includes a first section 251 and a second section 252 which extend side by side, the first section 251 has a first air inlet end 2511 and a first air outlet end 2512, and the second section 252 has a second air inlet end 2521 and a second air outlet end 2522, the first air inlet end 2511 is communicated with the first liquid storage cavity 211, and the second air outlet end 252 is communicated with the second liquid storage cavity 221 when the container 22 is connected with the atomization assembly 21.
[0080] When the cover assembly 219 as one of the movable members is located at the first position, the cover assembly 219 keeps a gap 2513 between the first air outlet end 2512 and the second air inlet end 2521 for the 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 is in an open state, and the air in the first liquid storage cavity 211 can enter into the second liquid storage cavity 221 through the second air guide channel R3 and / or the third air guide channel R4, as shown in Figure 8 .
[0081] When the cover assembly 219 is located at the second position, the cover assembly 219 blocks the first air outlet end 2512 and the second air inlet end 2521, so that the air in the first section 251 cannot enter into the second section 252, the second air guide channel R3 and / or the third air guide channel R4 is in a closed state, and the air in the first liquid storage cavity 211 cannot enter into the second liquid storage cavity 221 through the second air guide channel R4.
[0082] Specifically, as shown in Figure 10 and Figure 12As shown, the main housing 217 is formed with a tubular portion 2171, and a partition wall 2172 longitudinally extends inside the tubular portion 2171, and the inner wall of the tubular portion 2171 and the partition wall 2171 define at least part of the first section 251 and the second section 252 respectively. The sealing member 210 on the cover assembly 219 extends into the tubular portion 2171 and elastically abuts against the inner wall of the tubular portion 2171, and when the cover assembly 219 moves to the second position, the sealing member 210 abuts against the end face of the partition wall 2172 to seal the first air outlet end 2512 and the second air inlet end 2521.
[0083] In some embodiments, as shown in Figure 8 The atomizer 20 has a first end 203 and a second end 204 oppositely arranged along the length direction thereof, and the second section 252 extends substantially from the first end 203 to the second end 204, that is, part of the air passage of the second air guide channel R3 and / or the third air guide channel R4 is located above the first liquid storage cavity 211, so as to avoid the liquid medium in the first liquid storage cavity 211 from leaking into the second air guide channel R3 and / or the third air guide channel R4.
[0084] 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 seal the first air outlet end 2512 or the second air inlet end 2521, so that the air in the first section 251 cannot enter the second section 252.
[0085] In some embodiments, as shown in Figure 10 The atomizer 20 has a front side 201 and a rear side 202 along the thickness direction, and the thickness direction is the X direction in Figure 11 The second air guide channel R3 and the third air guide channel R4 are arranged in a spaced manner, and the second air guide channel R3 is arranged adjacent to the front side 201 of the atomizer 20, and the third air guide channel R4 is arranged adjacent to the rear side 202 of the atomizer 20. When the container 22 and the atomization assembly 21 are connected, and the movable member is in the first position, the second air guide channel R3 and the third air guide channel R4 are in a conductive state, and the atomizer 20 is in a horizontal state as shown in Figure 11 The liquid medium in the second liquid storage cavity 221 is at the bottom of the second liquid storage cavity 221 under the action of gravity, the air in the first liquid storage cavity 211 enters the second liquid storage cavity 221 through the second air guide channel R3, and the third air guide channel R4 serves as another liquid guide channel to conduct the liquid medium in the second liquid storage cavity 221 to the first liquid storage cavity 211.
[0086] When the liquid medium in the first liquid storage cavity 211 reaches saturation, the movable member moves from the first position to the second position, at which time the second air guide channel R3 and the third air guide channel R4 are both blocked by the movable member and closed, and the liquid guide channel R1 is in a conductive state, and the air in the first liquid storage cavity 211 and the liquid medium in the second liquid storage cavity 221 can only be conducted through the liquid guide channel R1.
[0087] Further in some embodiments, please refer to Figure 10 , along the thickness direction of the atomizer 20, the liquid guide channel R1 (i.e. the first air guide channel) is located between the second air guide channel R3 and the third air guide channel R4, so that the first air guide channel, the second air guide channel R3 and the second air guide channel R3 have a confluence R134, and then communicate to the second liquid storage cavity 221 through the confluence R134, so as to reduce the complexity of the design of the air guide channel structure. In some embodiments, as shown in Figure 2 , when the cover assembly 219 as one of the movable members is in the first position, the cover assembly 210 part protrudes from the main housing 217, and then the cover assembly 210 blocks the atomizer 20 from being accommodated in the accommodation cavity 13. When the cover assembly 219 moves to the second position, the atomizer 20 can be accommodated in the accommodation cavity 13, that is, when the cover assembly 219 moves to the second position, the cover assembly 219 unblocks the atomizer 20, and then allows the atomizer 20 to be accommodated in the accommodation cavity 13. In this way, the user can be reminded that the liquid medium has not been injected into the atomization assembly 21, that is, the liquid medium in the container 22 has not been introduced into the atomization assembly 21, which can effectively prevent the atomization assembly 21 from dry burning.
