[0026] Please refer to Figure 1 , which is a schematic structural diagram of the atomizer 10 in an embodiment.

[0027] An electronic atomization device includes an atomizer 10 and a battery host 20. The atomizer 10 and the battery host 20 are adapted and electrically connected. The atomizer 10 is an aerosol generating device of the electronic atomization device, which is used to generate heat under the condition of being powered on, so that the e-liquid in the atomizer 10 forms an aerosol for the user to inhale; the battery host 20 is the control center and power supply center of the electronic atomization device. The battery provides electrical energy for the circuit of the entire electronic atomization device, so that the control center is powered on to control the operation of each component in the circuit, enabling the atomizer 10 to be powered on and generate heat.

[0028] Specifically, please refer to Figure 2 , the atomizer 10 includes a housing assembly 12, an atomization assembly 14, a mouthpiece assembly 16 and a base 18. The mouthpiece assembly 16 and the base 18 are respectively arranged at both ends of the housing assembly 12, and the atomization assembly 14 is arranged inside the housing assembly 12; the atomization assembly 14 includes a first atomization assembly 142 and a second atomization assembly 144. The housing assembly 12 includes a separated first housing 121 and a second housing 122. The interior of the first housing 121 is separated into a first oil storage chamber 124 and a first atomization chamber 125 by a partition sleeve 123, and the first oil storage chamber 124 and the first atomization chamber 125 are communicated through a first oil guiding hole 1232. The interior of the second housing 122 is separated into a second oil storage chamber 126 and a second atomization chamber 127 by a partition sleeve 123, and the second oil storage chamber 126 and the second atomization chamber 127 are communicated through a second oil guiding hole 1234. The first atomization assembly 142 and the second atomization assembly 144 are respectively arranged in the first atomization chamber 125 and the second atomization chamber 127; a rotary connection structure 19 is arranged between the mouthpiece assembly 16 and the housing assembly 12. The mouthpiece assembly 16 is rotatably arranged on the housing assembly 12 through the rotary connection structure 19, and the mouthpiece assembly 16 can be selectively communicated with the first atomization chamber 125 or the second atomization chamber 127 through rotation.

[0029] Two oil storage chambers, namely the first oil storage chamber 124 and the second oil storage chamber 126, are arranged in the housing assembly 12 of the electronic atomization device. On the one hand, it can increase the storage capacity of the e-liquid, which is beneficial to the realization of a large-capacity e-liquid atomizer 10. On the other hand, through the two oil storage chambers, pressure sharing can be achieved. Compared with the situation where the e-liquid of the same capacity is placed in a large oil storage chamber, dividing the oil storage chamber into two can reduce the gravity and air pressure of the e-liquid in any one oil storage chamber, reducing the situation of oil leakage and liquid seepage; an atomization assembly 14 is arranged in each oil storage chamber to atomize the e-liquid, so that each oil storage chamber and the atomization assembly 14 can be used separately, without causing mixed pollution of the e-liquid, and different flavors of e-liquid can be filled in the two oil storage chambers for the user to choose, enriching the user experience; a rotary connection structure 19 is arranged between the mouthpiece assembly 16 and the housing assembly 12, so that the mouthpiece assembly 16 can rotate relative to the housing assembly 12. By rotating the mouthpiece assembly 16, it can be selectively communicated with the first atomization chamber 125 or the second atomization chamber 127, and the operation is simple and convenient.

[0030] Especially for the atomizer 10 with a large capacity, the commonly used atomizer 10 usually has a capacity of 2-5 ml. For a large-capacity atomizer 10 with a capacity of more than 8 ml, even more than a dozen milliliters, because the weight of the e-liquid itself is greater, the gravity and gas pressure of the e-liquid at the oil guiding hole near the bottom of the first oil storage cavity 124 are relatively large, making it easy for the e-liquid to leak out of the first oil storage cavity 124. In order to reduce or avoid the oil leakage problem, two oil storage cavities, namely the first oil storage cavity 124 and the second oil storage cavity 126, are provided. A relatively large amount of e-liquid is filled into the two separate oil storage cavities, reducing the gravity of the e-liquid at the bottoms of the first oil storage cavity 124 and the second oil storage cavity 126. At the same time, the gas pressure is also divided into two parts to achieve the effect of pressure division.

[0031] Among them, the atomization component 14 generally includes an oil guiding element and a heating element. The oil guiding element is used to absorb and conduct the e-liquid, and the heating element is used to heat and atomize the conducted e-liquid to form an aerosol for the user to inhale. The oil guiding element can be absorbent cotton, porous ceramics, porous metal, etc. Preferably, the atomization component 14 is a vertically arranged atomization core arranged along the axis of the atomization cavity. The heating element is arranged in a spiral shape, and the absorbent cotton is wrapped around the heating element for easy installation. A metal sleeve is also sleeved outside the atomization component 14. The atomization component 14 is arranged in contact with the inner wall of the metal sleeve, and holes are provided on the wall surface of the metal sleeve to communicate with the oil guiding holes. Further, absorbent cotton can also be provided in the gap between the outer wall of the metal sleeve and the inner wall of the partition sleeve 123, which is convenient for absorbing oil from the first oil storage cavity 124 and then supplying it to the oil guiding element for atomization.

[0032] Please refer to Figure 2 、 Figure 3 and Figure 4 In this embodiment, the rotary connection structure 19 includes a positioning buckle 192 and a positioning flange 194. The positioning buckle 192 is provided on one of the housing assembly 12 or the mouthpiece assembly 16, and the positioning flange 194 is provided on the other of the housing assembly 12 or the mouthpiece assembly 16. After the positioning buckle 192 is buckled to the positioning flange 194, the mouthpiece assembly 16 can rotate relative to the housing assembly 12. After the positioning buckle 192 is buckled to the positioning flange 194, the positions of the mouthpiece assembly 16 and the housing assembly 12 can be fixed, enabling the mouthpiece assembly 16 to only rotate axially relative to the housing assembly 12, and realizing selective communication and disconnection between the first atomization cavity 125 and the second atomization cavity 127 through rotation. The operation is simple and the structure is stable.

[0033] Preferably, the positioning buckle 192 and the positioning flange 194 are respectively provided at the central positions of the end faces of the housing assembly 12 or the mouthpiece assembly 16, and the structure of the electronic cigarette is preferably a centrally symmetric structure.

[0034] In another embodiment, the rotary connection structure 19 includes a rotary shaft, a rotary sleeve and a mounting groove. Mounting grooves are provided on the end faces where the housing assembly 12 and the nozzle assembly 16 are connected. The rotary shaft and the rotary sleeve are respectively arranged in the mounting grooves of the housing assembly 12 and the nozzle assembly 16. After the rotary sleeve is sleeved on the rotary shaft, the two are clamped and fixed, and can only rotate axially. The communication and disconnection between the first atomization chamber 125 and the second atomization chamber 127 are selectively realized through rotation, with simple operation and stable structure.

[0035] Preferably, the mounting groove is arranged at the central position of the end face of the housing assembly 12 or the nozzle assembly 16, and the structure of the electronic cigarette is preferably a central symmetric structure.

[0036] In this embodiment, the nozzle assembly 16 includes a nozzle 161, a nozzle cap 162 and a sealing cap 164. The nozzle 161 and the sealing cap 164 are both arranged on the nozzle cap 162 and correspond to the first atomization chamber 125 and the second atomization chamber 127 respectively. When the nozzle 161 is communicated with one of the first atomization chamber 125 and the second atomization chamber 127, the sealing cap 164 is hermetically isolated from the other of the first atomization chamber 125 and the second atomization chamber 127. That is, the battery main body 20 or the atomizer 10 of the electronic atomization device is provided with an air inlet channel for the air required for atomization to enter the interior of the electronic atomization device, and the air inlet channels of the first atomization chamber 125 and the second atomization chamber 127 are separately controlled. When the nozzle 161 is communicated with the first atomization chamber 125, the sealing cap 164 covers and seals the second atomization chamber 127. At this time, the first atomization chamber 125 communicates the air inlet channel with the nozzle 161, while the second atomization chamber 127 is blocked. When the first atomization component 142 is energized for atomization, the second atomization component 144 is not energized, and the second atomization chamber 127 is not ventilated, so that the e-liquid in the second oil storage chamber 126 will not be affected and the second atomization component 144 will not dry burn.

[0037] In this embodiment, the base 18 includes a sealing seat 182 and a bottom cover 184. The sealing seat 182 seals the first oil storage cavity 124 and the second oil storage cavity 126. A first liquid storage cavity 186 is provided between the sealing seat 182 and the bottom cover 184. A first liquid absorbing member 188 is provided in the first liquid storage cavity 186. The first liquid storage cavity 186 communicates with both the first atomization cavity 125 and the second atomization cavity 127. The condensate that may be formed after the e-liquid is atomized will gather and flow along the wall surface of the first atomization cavity 125 or the wall surface of the second atomization cavity 127 through the first atomization assembly 142 or the second atomization assembly 144, and finally drop into the first liquid storage cavity 186 and gather therein, avoiding the situation that if the condensate cannot be collected and sucked, it will be sucked into the mouth of the smoker along the wall surface of the atomization cavity, which is beneficial to improving the smoking taste. The first liquid absorbing member 188 can be absorbent cotton. The condensate gathered in the first liquid storage cavity 186 is absorbed by the first liquid absorbing member 188. Due to the good liquid absorption ability of the first liquid absorbing member 188, when the atomizer 10 is tilted or inverted, the liquid in the first liquid storage cavity 186 will not flow back into the first atomization cavity 125 or the second atomization cavity 127, improving the user experience.

[0038] Furthermore, both the housing assembly 12 and the bottom cover 184 are provided with partition structures. The sealing seat 182, the first liquid storage cavity 186 and the first liquid absorbing member 188 are each partitioned into two parts adapted to the first housing 121 and the second housing 122 through the partition structures. The first oil storage cavity 124 and the second oil storage cavity 126 are respectively sealed by the partitioned sealing seat 182, which can make their sealing performance better; and the first liquid storage cavity 186 and the first liquid absorbing member 188 are also partitioned and arranged, so that when one of the oil storage cavities is atomized, the liquid storage cavity and the liquid absorbing member below the other oil storage cavity can be kept dry and clean, which is beneficial to better adsorbing condensate.

[0039] Furthermore, a liquid guiding structure is provided in the first liquid storage cavity 186. One end of the liquid guiding structure is located in the first liquid storage cavity 186, and the other end communicates with the first oil storage cavity 124 or the second oil storage cavity 126 to introduce the liquid in the first liquid storage cavity 186 into the first oil storage cavity 124 or the second oil storage cavity 126. That is, the condensate gathered in the first liquid storage cavity 186 will be adsorbed and conducted by the liquid guiding structure to the first oil storage cavity 124 or the second oil storage cavity 126 and be reheated and atomized. Specifically, the liquid guiding structure can be a cotton strip or other fiber strips, or can also be a liquid guiding structure such as capillary pores or capillary tubes. In this embodiment, a liquid guiding cotton strip is adopted.

[0040] In this embodiment, the housing assembly 12 further includes an end cap 128 that seals the proximal end of the suction nozzle assembly 16. The end cap 128 seals the first oil storage cavity 124 and the second oil storage cavity 126, and is provided with a first air outlet hole 1282 and a second air outlet hole 1284 that communicate with the first atomization cavity 125 and the second atomization cavity 127 respectively. That is, the end cap 128 and the sealing seat 182 seal the e-liquid in the first oil storage cavity 124 and the second oil storage cavity 126 to prevent the e-liquid from leaking out. A second liquid storage cavity 166 is provided between the end cap 128 and the suction nozzle 161, and a sealing ring and a second liquid absorption member 168 are provided in the second liquid storage cavity 166. By providing the second liquid storage cavity 166 and the second liquid absorption member 168, the condensate formed during atomization can be absorbed by the second liquid absorption member 168 near the suction nozzle 161 during suction, preventing the condensate from being sucked into the mouth, which is beneficial to improving the smoking taste and user experience. At the same time, it further guarantees the absorption of condensate by the first liquid absorption member 188. Since the first liquid absorption member 188 is at the bottom of the first atomization cavity 125 and the second atomization cavity 127, the condensate formed when the atomization component 14 is heated and atomized and cooled may be sucked to the vicinity of the suction nozzle 161 due to the suction at the suction nozzle 161. At this time, the second liquid absorption member 168 can absorb the condensate here to prevent it from being sucked into the mouth.

[0041] In this embodiment, a first pneumatic sensor 22 and a second pneumatic sensor 24 are provided in the battery main body 20, and the first pneumatic sensor 22 and the second pneumatic sensor 24 are electrically connected to the first atomization component 142 and the second atomization component 144 respectively. That is, the first atomization component 142 and the second atomization component 144 are separately controlled by the first pneumatic sensor 22 and the second pneumatic sensor 24 respectively. When the first atomization component 142 is energized for atomization, the second pneumatic sensor 24 does not start. Similarly, when the second atomization component 144 is energized for atomization, the first pneumatic sensor 22 does not start. Different atomization components 14 are separately controlled by different pneumatic sensors, which can avoid the miscontrol of the pneumatic sensor when one of the atomization components 14 is not in use, and improve the safety and reliability of the product.

[0042] In this embodiment, both ends of the partition sleeve 123 are fixed to the end cap 128 and the sealing seat 182 respectively, and the outer wall of the atomization component 14 is wrapped with oil guide cotton and then placed in the partition sleeve 123.

[0043] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0044] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
