Referring to fig. 12-14, fig. 12 is a schematic perspective view of an atomizing device provided in some embodiments of the present application, fig. 13 is a schematic exploded view of an atomizing device provided in some embodiments of the present application, and fig. 14 is a cross-sectional view of an atomizing device provided in some embodiments of the present application. In some embodiments of the present disclosure, an atomization device is provided, which includes a housing 100 and an atomization assembly 200. The housing 100 is hollow inside such that the atomizing assembly 200 is mounted inside the housing 100. Illustratively, the hollow portion in the housing 100 extends to the bottom surface of the housing 100 to form the mounting port 11, so that the atomization assembly 200 is installed in the housing 100 from the mounting port 11 to form a complete atomization device. When the atomizing assembly 200 is installed in the housing 100, the atomizing assembly 200 atomizes the medium injected or installed in the atomizing device, so that the finally atomized gas is discharged from the gas outlet located at the top of the housing 100, and a user can conveniently inhale the gas by aiming at the gas outlet.

A hollow air duct 13 is disposed inside the casing 100, the air duct 13 extends to the top of the casing 100 to form an air outlet, and the atomized air flows along the air duct 13 from bottom to top to be discharged. Illustratively, the airway tube 13 is disposed in a vertical orientation. During use, it was found that condensation eventually formed on the inner wall of the gas duct 13 due to insufficient atomization and gas remaining in the gas duct 13. Through setting up the air duct pipe 13 that vertical direction extends for the condensate receives its dead weight to influence and drips downwards, and atomizing gas flows along vertical direction upflow, with the probability that reduces the condensate droplet and is inhaled by the user along with gaseous, thereby is favorable to improving user's experience.

Further, a liquid storage bin 14 is arranged in the housing 100, and the liquid storage bin 14 is located above the atomizing assembly 200. The installation position of the atomization assembly 200 corresponds to the position of the liquid storage bin 14, so that the liquid storage bin 14 is atomized by flowing into the atomization assembly 200 under the action of self weight.

Referring to fig. 1 and 2, fig. 1 is a schematic perspective view of an atomizing assembly provided in some embodiments of the present application, and fig. 2 is an exploded schematic view of the atomizing assembly provided in some embodiments of the present application. In some embodiments of the present application, the atomizing assembly 200 includes an upper seat 21, a lower seat 22, and an atomizing core 26. The upper seat 21 and the lower seat 22 are connected to form a support structure of the atomizing assembly 200. The upper seat 21 and the lower seat 22 are integrally connected to each other, a hollow portion 201 is formed therebetween, and the atomizing core 26 is accommodated in the hollow portion 201. The upper seat 21 is provided with an upper cavity 202, the lower seat 22 is provided with a lower cavity 203, and when the upper seat 21 is connected with the lower seat 22, the upper cavity 202 and the lower cavity 203 are combined to form a hollow part 201. In particular, with further reference to fig. 9-11, fig. 9 isbase:Sub>A bottom view of an atomizing assembly provided by some embodiments of the present application, fig. 10 isbase:Sub>A cross-sectional view taken atbase:Sub>A-base:Sub>A in fig. 9, and fig. 11 is an enlarged partial schematic view taken at D in fig. 10. The upper seat 21 and the lower seat 22 are detachably connected to each other, so that the parts such as the atomizing core 26 in the hollow portion 201 can be replaced by disassembling and assembling the parts. The upper seat 21 and the lower seat 22 are sequentially arranged in an up-and-down layout structure. An air passage hole 2161 is provided in the upper seat 21, wherein the air passage hole 2161 extends downward from the top surface of the upper seat 21 to communicate with the hollow portion 201, and the air passage hole 2161 extends to the side wall surface of the hollow portion 201 and forms an opening 2162 in the side wall surface. The air passage hole 2161 is connected with the air passage pipe 13, and the air passage hole 2161 is positioned at the bottom of the air passage pipe 13. Illustratively, the air passage hole 2161 extends in a vertical straight direction, so that the inner wall of the air passage hole 2161 is smooth and has no bosses. The liquid beads at the position of the opening 2162 are convenient to be completely discharged from the opening 2162 under the influence of self weight, and the liquid accumulation at the boss is avoided, so that the liquid beads are difficult to be completely discharged.

However, as the number of puffs of the atomizer increases, the condensate on the inner wall of the airway tube 13 will gradually increase. At this time, the condensate will be collected at the position of the opening 2162 of the air passage hole 2161 by its own weight. Meanwhile, since the cross-sectional area of the air passage hole 2161 is small, a large amount of condensate will form a water film to block one end of the air passage pipe 13 due to the influence of surface tension. If this happens, the user again sucks on the film of water and breaks up, and the small water particles dispersed at the break are simultaneously inhaled by the user with the ascending air flow.

To this end, as shown in fig. 10 and 11, and with further reference to fig. 4 and 5, fig. 4 is a schematic perspective view of a first perspective view of an upper seat in an atomizing assembly according to some embodiments of the present disclosure, and fig. 5 is a schematic partial enlarged view at B in fig. 4. The upper seat 21 further comprises a puncture unit 217, and the puncture unit 217 is located at one side of the upper seat 21 close to the hollow portion 201. The puncture unit 217 includes a fixed beam 2171 and a rib block 2172. The securing beam 2171 is used to secure the puncture unit 217 within the hollow 201, and the bead block 2172 is provided on the securing beam 2171 and extends toward the airway hole 2161. The water film clogging the air passage hole 2161 is pierced by the bead pieces 2172 to break the tension of the condensate, so that the condensate flows down along the bead pieces 2172. The air channel hole 2161 is ensured to be smooth, and the condensate is prevented from being inhaled by the user along with the air. The suction experience of the atomization device is improved.

The top surface of the bead block 2172 is flush with the opening 2162 or the bead block 2172 is approximately flush near the opening 2162 to facilitate contact of the bead block 2172 with a film of water to break the film of water. Preferably, the bead block 2172 extends to near the opening 2162, the top surface of the bead block 2172 being approximately flush with the opening 2162, and in particular, the bead block 2172 is positioned near the opening 2162 with a gap therebetween. The water film is under surface tension and gravity combined action for the water film protrusion is in uncovered 2162 when the water film is attached to uncovered 2162 department, and water film surface 2163 is the circular-arc that is protruding downwards. The top surfaces of rib pieces 2172 may be positioned to contact the water sheeting surfaces 2163 projecting above openings 2162 to break the surface tension of the water sheeting. The water film surface 2163 is spaced a distance L furthest from the opening 2162 in the vertical direction, and the top surface of the bead block 2172 is spaced from the opening 2162 by a distance in the range of 0-L.

Since the cross-sectional area of the air passage hole 2161 is small, extending the bead 2172 into the opening 2162 will cause the cross-sectional area of the opening 2162 to be reduced, thereby affecting the air intake efficiency. On the other hand, after the rib block 2172 extends into the opening 2162, the space between the outer side wall of the rib block 2172 and the inner wall of the opening 2162 becomes smaller, so that condensate is easily attached between the outer side wall of the rib block 2172 and the inner wall of the opening 2162 to form a local water film. This makes it impossible to completely solve the problem of the water film blocking the airway. In the present embodiment, since there is a gap between the rib 2172 and the opening 2162, it is difficult for the condensate to form a water film between the opening 2162 and the rib 2172, and the rib 2172 is located on the surface of the water film, so as to ensure that the rib 2172 is easy to break the water film and break the tension. And the convex rib block 2172 does not reduce the sectional area of the opening 2162, thus ensuring the air intake efficiency.

Illustratively, the rib pieces 2172 are of a conical structure, and the cross-sectional area of the rib pieces 2172 decreases as the rib pieces 2172 approach the opening 2162, so that the contact area of the rib pieces 2172 with the water film is small, and the pressure of the top of the rib pieces 2172 against the water film is increased, thereby making the rib pieces 2172 easier to puncture the water film.

In some embodiments of the present application, the fixed beam 2171 is integrally bonded to the body of the upper seat 21 such that the fixed beam 2171 spans the upper cavity 202. The upper cavity 202 is divided into an upper cavity 2021 and a lower cavity 2023 which are sequentially arranged up and down by a fixed beam 2171. The atomizing core 26 is accommodated in an accommodating space formed by the lower cavity 2023 and the lower cavity 203. The fixed beam 2171 is located directly below the airway hole 2161. A rib mass 2172 is disposed within the upper cavity 2021. Illustratively, the rib piece 2172 protrudes vertically from the side of the fixing beam 2171 toward the air passage hole 2161, and the length of the rib piece 2172 is shortened to increase the strength of the rib piece 2172 when the distance between the rib piece 2172 and the opening 2162 is satisfied.

When the atomizing core 26 is located in the lower cavity 2023, the fixed beam 2171 is located right below the atomizing core 26, the fixed beam 2171 is located between the atomizing core 26 and the air passage hole 2161, and the atomizing core 26 needs to pass through the fixed beam 2171 to enter the air passage hole 2161. The fixed beam 2171 is positioned to block the airway hole 2161 to affect the patency of the gas entering the airway hole 2161, resulting in a small amount of gas being expelled from the airway tube 13; more seriously, the gas which is difficult to be discharged from the gas passage hole 2161 is accumulated in the hollow portion 201, and the gas pressure of the hollow portion 201 is gradually increased with the increase of time, which is easy to cause danger. To ensure that gas can pass smoothly through the fixed beam 2171 into the gas passage holes 2161. In this scheme, the fixed beam 2171 is gone up and is seted up along the air current direction of flow and dodge the groove 2022, makes things convenient for gas to pass fixed beam 2171 and flow to air flue hole 2161 through setting up the groove 2022 of dodging to can effectively improve gaseous flow efficiency.

Meanwhile, since the atomizing core 26 is located directly below the fixed beam 2171. In order to guide the liquid in the liquid storage bin 14 into the atomizing core 26, a hollow liquid inlet channel 219 is formed in the upper seat 21, and one end of the liquid inlet channel 219 extends to the bottom surface of the fixed beam 2171 to form the liquid inlet 214. Wherein, the bottom surface of the fixed beam 2171 is the side surface of the fixed beam 2171 close to the atomizing core 26, and the position of the liquid inlet 214 on the fixed beam 2171 is consistent with that of the atomizing core 26, so that the liquid flows downwards in the liquid inlet channel 219 and finally flows into the atomizing core 26 through the liquid inlet 214 precisely, so as to complete the liquid guiding process.

Further, an inner seal 25 is provided between the fixed beam 2171 and the atomizing core 26. The inner sealing piece 25 is arranged around the periphery of the liquid inlet 214, and the atomizing core 26 is extruded on the inner sealing piece 25. The inner sealing piece 25 is used for sealing the liquid inlet 214 and the atomizing core 26, so that the liquid is prevented from leaking from a gap at the joint of the liquid inlet 214 and the atomizing core 26.

Illustratively, the relief grooves 2022 are disposed on both sides of the fixed beam 2171, and the relief grooves 2022 are outside the liquid inlet 214. The relief groove 2022 correspondingly extends to the side surface of the upper seat 21. The atomized gas enters the upper chamber 2021 from both sides of the liquid up and eventually into the airway tube 13. The transmission channels of gas and liquid are mutually separated, so that the doping of gas and liquid is reduced as much as possible, the situation that a user inhales gas and liquid at the same time is reduced, and the use experience of the user is improved.

Further, in order to improve the sealing performance of the atomization device, the atomization assembly 200 further includes an outer seal member, and the outer seal member is pressed against the outer wall of the atomization assembly 200 through the inner wall of the housing 100, so that the outer seal member blocks the gas and the liquid from passing through.

Illustratively, as shown in fig. 2-4, fig. 3 is an enlarged view of a portion of fig. 2 at a. The outer seal member includes a first seal member 23 and a second seal member 24, and the first seal member 23 and the second seal member 24 are correspondingly connected to the upper seat 21 and the lower seat 22. Wherein, the upper seat 21 comprises a connection unit 216, the connection unit 216 is located above the upper cavity 2021, and the air passage hole 2161 is disposed on the connection unit 216. The first sealing member 23 is sleeved on the connection unit 216 to connect the first sealing member 23 with the upper seat 21. Specifically, the first sealing element 23 is provided with a deep groove 231 matched with the connecting unit 216, and the deep groove 231 is covered on the connecting unit 216. The deep groove 231 is provided with an air outlet 232, and when the deep groove 231 is coated on the connecting unit 216, the air outlet 232 is embedded in the air passage hole 2161. The first sealing member 23 further includes a liquid inlet hole 233, and two ends of the liquid inlet hole 233 are respectively connected to the liquid storage chamber 14 and the liquid inlet passage 219. Because the first sealing member 23 is an elastic member, when the atomizing assembly 200 is assembled in the housing 100, the first sealing member 23 is simultaneously subjected to the pressing force of the upper seat 21 and the liquid storage chamber 14 and the pressing force of the upper seat 21 and the inner wall of the housing 100, so that the first sealing member 23 has a better sealing effect on both liquid and gas.

Referring to fig. 8, fig. 8 is a schematic perspective view of an inner lower seat of an atomizing assembly according to some embodiments of the present disclosure. A sealing groove 227 is formed on the outer surface of the lower seat 22, and the second sealing member 24 is disposed in the sealing groove 227, so that the lower seat 22 presses the second sealing member 24 against the inner wall of the casing 100, thereby sealing the position where the second sealing member 24 is disposed on the lower seat 22.

The first seal 23 and the second seal 24 are sequentially provided at upper and lower ends of the hollow portion 201 formed between the upper seat 21 and the lower seat 22. The hollow portion 201 can be sealed by the first sealing member 23 and the second sealing member 24, so as to prevent liquid and gas from leaking from the gap between the atomizing assembly 200 and the housing 100.

As shown in fig. 4 and 8, in some embodiments of the present application, the upper seat 21 includes a clamping unit 212, and the lower seat 22 includes a limiting unit 229 adapted to the clamping unit 212; the relative position relationship between upper seat 21 and lower seat 22 is limited by the nesting arrangement of clamping unit 212 and limiting unit 229. The upper cavity 202 is disposed in the clamping unit 212, and the lower cavity 203 is disposed in the stopper unit 229.

Illustratively, the latch unit 212 extends downward from the bottom surface of the body of the upper housing 21 to form a raised positioning structure.

The lower holder 22 moves relative to the upper holder 21 so that the stopper unit 229 slides in the direction in which the stopper groove 215 extends. When the stopper unit 229 is moved to the fixed mounting position, the stopper unit 229 is in fixed connection with the clamping unit 212, so that the upper seat 21 and the lower seat 22 are maintained in a relatively stationary positional relationship. Because the upper cavity 202 and the lower cavity 203 are respectively positioned in the clamping unit 212 and the limiting unit 229; when the clamping unit 212 slides relative to the limiting unit 229 so that the clamping unit 212 and the limiting unit 229 are partially overlapped, the upper cavity 202 and the lower cavity 203 are partially overlapped to form the hollow part 201. More specifically, the lower cavity 2023 in the upper cavity 202 overlaps with the lower cavity 203, and the limit unit 229 slides in the limit groove 215, so that the volume of the lower cavity 2023 is ensured to be unchanged during the sliding process, and the volume of the lower cavity 203 is changed accordingly.

The number of the clamping units 212 is two, the number of the limiting units 229 is the same as that of the clamping units 212, and the clamping units 212 and the limiting units 229 are arranged in a one-to-one correspondence mode. The clamping units 212 are arranged on the upper seat 21 at intervals, and the upper cavity 202 is positioned in the space between the two clamping units 212; correspondingly, the lower cavity 203 is located in the space between the two spacing units 229.

Further, when the clamping unit 212 and the spacing unit 229 are connected, a lower cavity 2023 is formed inside the clamping unit 212 and the spacing unit 229, and an air inlet hole 223 is formed on the lower seat 22, wherein the air inlet hole 223 is used for filling external air into the lower cavity 2023. The upper seat 21 is provided with a ventilation slot 213, one end of the ventilation slot 213 extends to the liquid inlet 214, and the other end extends to the bottom surface close to the clamping unit 212, so that the external air entering the lower cavity 2023 can enter the liquid inlet channel 219 via the ventilation slot 213 to balance the air pressure in the liquid storage chamber 14. Because the first sealing member 23 and the inner sealing member 25 that the upper seat 21 set up can effectively improve the leakproofness of entering liquid storage bin 14 to atomizing core 26 between liquid passage, consequently, along with the consumption of liquid in the liquid storage bin 14, the liquid level in the liquid storage bin 14 descends gradually, lead to the atmospheric pressure in the liquid storage bin 14 to reduce, if there is not outside air to supply to the interior liquid unsmooth that will make liquid storage bin 14 in the liquid storage bin 14, and along with the liquid reduction of direction atomizing core 26, atomizing core 26's heating module easily burns futilely, make the gaseous of deriving appear pasting the flavor, influence the use and experience. To this end, referring to fig. 6 and 7, fig. 6 is a perspective view illustrating a second perspective view of an upper seat in an atomizing assembly according to some embodiments of the present application, and fig. 7 is an enlarged view of a portion at C in fig. 6.

The two liquid storage bins 14 are ventilated through the independent ventilation slots 213, so that the two liquid storage bins 14 independently keep the air pressure balance in the two liquid storage bins 14, and the two liquid storage bins 14 can independently supply liquid to the atomizing core 26. On the other hand, the two air exchanging grooves 213 are arranged close to the corresponding liquid inlet channels 219, so that the length of the single air exchanging groove 213 can be shortened, and the whole structure is more compact.

Specifically, the guide 27 is located directly below the atomizing core 26, and the liquid suction portions 28 are located on both sides of the guide 27. The volume of deriving liquid in the stock solution storehouse 14 is difficult to control, and atomizing core 26 is difficult to accurate control simultaneously for atomizing core 26 often can appear not fully atomizing liquid and drip under the action of gravity, finally leads to liquid to spill from the atomizing device. In order to avoid the problem of liquid leakage, in the present application, the guide 27 receives the liquid dropping from the atomizing core 26 and guides the dropping liquid into the liquid suction portion 28, so that the liquid leakage can be effectively avoided. Although not shown, it is understood that the liquid collected on the liquid suction portion 28 will eventually flow back into the atomizing core 26, so that the insufficiently atomized liquid can further undergo the atomizing process, and the efficiency of the liquid can also be improved.
