As shown in fig. 1 to 6, the electronic atomization device 100 includes an upper housing 10, a first sealing member 11, a second sealing member 12, a base 13, a delivery tube 14, an atomization core 15, a sleeve 16, a suction nozzle 17, a liquid absorbing member 18, a liquid storage member 19, a lower housing 20, an electric core 21, an airflow sensor 22, and a casing 23.

Both the upper and lower ends of the upper casing 10 are open ends. A first sealing member 11 is provided at the upper end of the upper case 10, and a second sealing member 12 is provided at the lower end of the upper case 10.

The first sealing element 11 and the second sealing element 12 are made of sealing material, such as silicon gel.

The outer side wall of the first seal member 11 has a radially extending projection 111, and a portion of the first seal member 11 located below the projection 111 projects into the upper casing 10. The outer side wall of the first seal 11 abuts against the inner side wall of the upper housing 10 to form a seal; further, the outer side wall of the first sealing member 11 has a convex ring to form a good sealing effect with the inner side wall of the upper housing 10. An end surface of the upper end of the upper case 10 abuts against the lower surface of the projection 111 to form a seal.

Similarly, the outer side wall of the second seal member 12 has a radially extending projection 121, and the portion of the second seal member 12 above the projection 121 extends into the upper casing 10. The outer side wall of the second seal 12 abuts the inner side wall of the upper housing 10 to form a seal; further, the outer side wall of the second sealing member 12 has a convex ring to form a good sealing effect with the inner side wall of the upper casing 10. The end surface of the lower end of the upper case 10 abuts the upper surface of the projection 121 to form a seal.

The first seal member 11 has a through hole 112, and the second seal member 12 has a through hole 122. The lower end of the base 13 is housed or held in the through hole 122, the upper end of the transfer tube 14 is housed or held in the through hole 112, and the lower end of the transfer tube 14 is housed in the base 13 and abuts against the end surface of the upper end of the atomizing core 15. Thus, the base 13 and the vent tube formed by the transfer tube 14 together define an airflow channel of the electronic atomizer 100.

The base 13 has a receiving chamber therein for receiving the atomizing core 15. The side wall of the base 13 is provided with a liquid passing hole 131 for communicating the liquid storage cavity with the atomizing core 15, and the sleeve 16 is sleeved on the base 13 and the transmission pipe 14; the cannula 16 can aspirate the liquid matrix stored in the reservoir and deliver it to the atomizing core 15 through the liquid passage hole 131. In other examples, the sleeve 16 may also be omitted.

The atomizing core 15 is disposed adjacent to the second seal 12. The atomizing core 15 includes a liquid guide member 151 and a heating member 152. The liquid guiding element 151 may be made of, for example, cotton fiber, metal fiber, ceramic fiber, glass fiber, porous ceramic, etc., and is preferably a tubular structure made of cotton fiber and configured to extend along the longitudinal direction of the electronic atomization device 100. The heating element 152 is a heat generating mesh made of a resistive material. Heating element 152 may be disposed on an inner wall of liquid conducting element 151.

In other examples, the atomizing core 15 may be arranged to extend along a transverse direction of the electronic atomizing device 100, such as: the heating element 152 is wound on the liquid guide element 151 and transversely penetrates through the base 13; wherein the heating element 152 is disposed in the base 13, and the two ends of the fluid-guiding element 151 can extend into the liquid storage cavity.

The aerosol generated by heating the atomizing core 15 and atomizing can be conveyed through the conveying pipe 14 towards the mouthpiece 17.

The part of the first sealing member 11 above the projection 111 extends into the suction nozzle 17, and the end surface of the lower end of the suction nozzle 17 abuts against the upper surface of the projection 111 to form a seal. The suction nozzle 17 has a connection pipe 171 extending downward from a nozzle end, the connection pipe 171 communicating with the through-hole 112; the aerosol generated by heating and atomizing the atomizing core 15 can flow out of the mouth end through the transmission pipe 14, the through hole 112 and the connecting pipe 171. In a further implementation, the first sealing member 11 has a first groove 113, the liquid absorbing member 18 is disposed in the first groove 113, the liquid absorbing member 18 has a passage for the air flow to pass through; in this way, the absorbent member 18 can absorb the condensed liquid substrate in the mouthpiece 17.

The gap between the upper housing 10, the first seal 11, the second seal 12, the base 13 and the transfer tube 14 defines a reservoir chamber (not shown) for storing a liquid matrix.

The first seal member 11 also has a second recess 114, the second recess 114 defining or forming a first reservoir space of the reservoir; the second seal member 12 has a recess 123, the recess 123 defining or forming a second reservoir space of the reservoir; a portion of the reservoir between the first and second reservoirs defines or forms a third reservoir. The first liquid storage space, the third liquid storage space and the second liquid storage space are sequentially arranged along the longitudinal direction of the electronic atomization device 100.

The reservoir 19 is arranged or received in the third reservoir space, the reservoir 19 not extending to the first reservoir space or the second reservoir space. The reservoir 19 is preferably made of cotton fibers. The reservoir 19 is for adsorbing liquid matrix to thereby retain at least a portion of the liquid matrix in the third reservoir space. The liquid storage member 19 has through holes (not shown) penetrating through upper and lower ends thereof to be fitted over the base 13 and the transfer pipe 14. The reservoir 19 may be held in contact with the end face of the lower end of the first seal 11 and/or the end face of the upper end of the second seal 12 to be held between the first seal 11 and the second seal 12.

In other examples, it is also possible that the first seal 11 does not form a first reservoir, i.e. the reservoir comprises a portion substantially within the upper housing 10 and another portion formed within the second seal 12. It is also possible, on the contrary, that the second seal 12 does not form the second reservoir, whereas the first seal 11 forms the first reservoir.

The volumes of the first and second reservoir spaces are both less than the volume of the third reservoir space, preferably the volume of the first reservoir space is greater than the volume of the second reservoir space. Typically, the volumes of the first reservoir space and the second reservoir space are both between 1ml and 4ml; preferably, between 1ml and 3ml. The ratio of the volume of the third liquid storage space to the volume of the first liquid storage space is 5-8; preferably, between 5 and 7; the ratio of the volume of the third reservoir space to the volume of the second reservoir space is similar. Specifically, the third reservoir space may have a volume of 10ml, the second reservoir space may have a volume of 2ml, and the first reservoir space may have a volume of 3ml. Like this, through the first stock solution space that forms in first sealing member 11 and the second stock solution space that forms in second sealing member 12, increased the volume of stock solution chamber among the current electron atomizing device, promoted user's use and experienced.

The side wall of the first liquid storage space is inclined to the longitudinal direction of the electronic atomization device 100, and the side wall of the second liquid storage space is inclined to the longitudinal direction of the electronic atomization device 100. The side wall of the first liquid storage space has an angle of 10 to 20 ° (preferably, 12 to 20 °; more preferably, 14 to 18 °; more preferably, 14 to 16 °), with the longitudinal direction of the electronic atomization device 100), and the side wall of the second liquid storage space has an angle of 10 to 20 ° (preferably, 12 to 20 °; more preferably, 14 to 18 °; more preferably, 14 to 16 °), with the longitudinal direction of the electronic atomization device 100. Thus, when the electronic atomization device 100 is placed vertically (shown in fig. 2), a portion of the liquid substrate stored in the reservoir chamber can be stored in the second reservoir space, and the liquid substrate stored in the first reservoir space can flow toward the reservoir member through the inclined side wall; when the electronic atomization device 100 is placed upside down (after being rotated 180 degrees in the orientation shown in fig. 2), a portion of the liquid substrate stored in the reservoir chamber may be stored in the first reservoir space, and the liquid substrate stored in the second reservoir space may flow toward the reservoir member through the inclined sidewall. In this way, accumulation of liquid substrate at one end of the reservoir 19, which in turn may lead to leakage of liquid substrate out of the weep hole 131, is avoided.

Further, a first capillary groove 114a is arranged on the side wall of the first liquid storage space, and the first capillary groove 114a extends from the top wall of the first liquid storage space to the direction of the second liquid storage space; and a second capillary groove 123a is arranged on the side wall of the second liquid storage space, and the second capillary groove 123a extends from the bottom wall of the second liquid storage space to the direction of the first liquid storage space. The width of the first capillary groove 114a is 0.1mm to 1mm (preferably, 0.1mm to 0.8mm; preferably, 0.1mm to 0.7mm; preferably, 0.2mm to 0.7mm; preferably, 0.4mm to 0.7mm; preferably, 0.5mm to 0.7 mm), and the width of the second capillary groove 123a is 0.1mm to 1mm (preferably, 0.1mm to 0.8mm; preferably, 0.1mm to 0.7mm; preferably, 0.2mm to 0.7mm; preferably, 0.4mm to 0.7mm; preferably, 0.5mm to 0.7 mm).

The upper end of the lower case 20 is an open end and the lower end is a closed end. An end surface of the upper end of the lower case 20 abuts against the lower surface of the projection 121 to form a seal. The outer shell 23 is sleeved outside the upper shell 10 and the lower shell 20, the end surface of the upper end of the outer shell 23 is abutted with the surface of the outward radial protruding part of the suction nozzle 17, the end surface of the lower end of the outer shell 23 is abutted with the surface of the outward radial protruding part of the lower shell 20, and both the protruding part 111 and the protruding part 121 can be abutted with the inner surface of the outer shell 23 to form sealing. The upper case 10, the lower case 20, and the housing 23 constitute a case assembly of the electronic atomizer 100. In other examples, no housing 23 is possible. In other examples, the upper case 10, the lower case 20, and the outer case 23 may be integrally formed.

The battery cell 21 is disposed in the lower case 20 below the second seal member 12. The battery cell 21 supplies power for operating the electronic atomization device 100. The battery cell 21 may be a rechargeable battery or a disposable battery. Preferably a rechargeable battery is used.

The closed end of the lower housing 20 is provided with an air inlet, through which external air flows into the electronic atomization device 100, flows into the atomization core 15 through the through hole 122, and flows out from the nozzle end of the nozzle 17 after sequentially passing through the transmission tube 14, the through hole 112, and the nozzle 17 together with aerosol generated by heating and atomization.

The lower case 20 is also provided therein with a housing chamber in which the airflow sensor 22 is housed. The airflow sensor 22, such as a microphone, controls the atomizing core 15 to start operating when sensing that the electronic atomizer 100 is being sucked.

Note that, in the example of fig. 1 to 6, the electronic atomization device 100 is integrated. In other examples, the electronic atomizer device 100 may be a cartridge or an atomizer used in combination with a power supply device; for example, the electronic atomization device 100 and the power supply device are detachably connected, the upper housing 10, the first sealing member 11, the second sealing member 12, the base 13, the delivery tube 14, the atomization core 15, the sleeve 16, the suction nozzle 17, the liquid absorbing member 18 and the liquid storage member 19 may be disposed in the electronic atomization device 100, and the lower housing 20, the electric core 21 and the airflow sensor 22 may be disposed in the power supply device.
