In this embodiment, the atomizer 100 and the main body 200 are illustrated by adopting an integral fixed connection manner, and in other embodiments, a detachable connection manner may be adopted according to actual situation needs.

Referring to fig. 2 and 3, the main body 200 includes a housing 201, a mounting bracket 202 disposed in the housing 201, a power supply 203, a microphone switch 204, and a control circuit board 205, where the power supply 203, the microphone switch 204, and the control circuit board 205 are all fixedly mounted on the mounting bracket 202, the microphone switch 204 is used for sensing a trigger signal generated by the atomizer 100 when the atomizer 100 is in a suction state (e.g. detecting a change of air pressure/air flow), and the control circuit board 205 is used for controlling the power supply 203 to supply power to the atomizer 100 according to the trigger signal, so that the atomizer 100 heats and atomizes the atomized liquid stored therein to generate aerosol for the user to suck.

The atomizer 100 in the present embodiment includes an oil cup 10, an atomizing assembly 50, a first sealing member 20, a supporting member 30, and a movable valve 40, a first partition plate 11 and a second partition plate 12 are formed in the oil cup 10 to partition an inner space of the oil cup 10 into a main oil chamber 13, a first auxiliary oil chamber 14, and a second auxiliary oil chamber 15 which are arranged side by side in the lateral direction and are sequentially communicated, a first communication hole 111 is formed in the first partition plate 11 to communicate the main oil chamber 13 with the first auxiliary oil chamber 14, and a second communication hole 121 is formed in the second partition plate 12 to communicate the first auxiliary oil chamber 14 with the second auxiliary oil chamber 15, respectively; the oil cup 10 is provided with a suction nozzle structure 16 protruding from the upper end of the main oil cavity 13, a suction hole 161 is formed at the top end of the suction nozzle structure 16, and an air duct 162 extending into the main oil cavity 13 is formed on the inner wall of the oil cup 10 protruding inwards along the edge of the suction hole 161. In the present embodiment, the air duct 162, the first partition plate 11, and the second partition plate 12 are integrally formed with the oil cup 10.

The atomizing assembly 50 is arranged in the bottom end of the main oil cavity 13 and encloses the main oil cavity 13 together with the oil cup 10; the first sealing member 20 is preferably made of a silicone material, is mounted on the bottom of the oil cup 10, and forms the first auxiliary oil chamber 14 and the second auxiliary oil chamber 15 together with the oil cup 10, wherein the top surface of the first sealing member 20 serves as the bottom wall of the first auxiliary oil chamber 14 and the second auxiliary oil chamber 15, a notch is formed in the bottom end of the second partition plate 12, the bottom end of the second partition plate 12 abuts against the top surface of the first sealing member 20, and the second communication hole 121 is formed together with the first sealing member 20 through the arrangement of the notch.

Referring to fig. 6, the supporting member 30 is made of hard plastic, and is mounted in the bottom end of the first sealing member 20, a return air port 21 is formed on the first sealing member 20 corresponding to the second auxiliary oil cavity 15, a return air channel 24 is formed between the first sealing member 20 and the supporting member 30, one end of the return air channel 24 is communicated with the return air port 21, and the other end is directly or indirectly communicated with the outside air. In this way, the auxiliary oil cavity is plugged and sealed by the cooperation of the supporting piece 30 and the first sealing piece 20, so that the first sealing piece 20 can be supported, and the first sealing piece 20 is prevented from being displaced to influence the sealing effect; in addition, since the oil cup 10 is prone to sagging during injection molding, the assembly with the first seal member 20 and the sealing effect are affected, and the structure of the first seal member 20 and the support member 30 in this embodiment reduces the requirement for the dimensional accuracy of the oil cup 10.

It should be understood that when the user performs suction, the atomized liquid in the main oil chamber 13 is heated and atomized by the atomizing assembly 50, the negative pressure of the cavity in the main oil chamber 13 increases, and at the same time, since the air return passage 24 introduces air into the second auxiliary oil chamber 15 to balance the air pressure with the external air, the atomized liquid in the first auxiliary oil chamber 14 is replenished into the main oil chamber 13 through the first communication hole 111, the atomized liquid in the second auxiliary oil chamber 15 is replenished into the first auxiliary oil chamber 14 through the second communication hole 121, the atomized liquid in the second auxiliary oil chamber 15 is reduced, the liquid level is reduced, and the ventilation is smoother, thereby realizing reliable oil supply to the atomizing assembly 50, and preventing the problem of scorching smell due to insufficient oil supply.

As shown in fig. 4, the movable valve 40 is provided at the second communication hole 121 and is movable between an open position and a closed position to open or close the communication hole; when the atomizer 100 is in the upright state, the movable valve 40 is moved to the open position by gravity, and at this time, the second communication hole 121 between the first auxiliary oil chamber 14 and the second auxiliary oil chamber 15 is in the communication state, and the atomizer 100 can perform suction normally; when the atomizer 100 is in the inverted state, the movable valve 40 moves to the closed position under the action of gravity, and at this time, the movable valve 40 closes the second communication hole 121, so as to avoid that atomized liquid in the first auxiliary oil chamber 14 enters into the second auxiliary oil chamber 15, reduce the problem that when in inverted state, the main oil chamber 13 cannot supply liquid to the atomizing assembly 50 due to insufficient smoke oil quantity, and cause dry burning, and simultaneously, prevent bubbles in the auxiliary oil chamber communicated with the air return channel 24 when in inverted from flowing to the main oil chamber or other auxiliary oil chambers, and influence the pressure distribution state of the main oil chamber 13 and the auxiliary oil chamber when in subsequent inverted return to the upright state, thereby influencing the problem of liquid supply when in subsequent upright use.

That is, in the embodiment of the atomizer 100 of the present utility model, the communication hole where the movable valve 40 is located is closed by the action of the movable valve 40 when the atomizer 100 is in the inverted state, so as to prevent the atomized liquid in the main oil chamber 13 or other auxiliary oil chambers from entering the auxiliary oil chamber communicated with the air return channel 24, thereby ensuring that the atomizer 100 has a good ventilation effect; the arrangement of the movable valve 40 may be adjusted according to actual design requirements, and in other embodiments, the movable valve 40 may be disposed at the first communication hole 111, so long as the movable valve 40 can separate the main oil chamber 13 from the auxiliary oil chamber communicated with the air return channel 24 when the atomizer 100 is in an inverted state.

It should be noted that, when the atomizer 100 works for a period of time, there is floating foam generated when the air returns in the second auxiliary oil chamber 15, if the floating foam enters the first auxiliary oil chamber 14 through the second communication hole 121, even after the floating foam enters the main oil chamber 13 from the first auxiliary oil chamber 14, the atomizer 100 is more prone to generating snoring when being sucked; in contrast, in the present embodiment, by providing the movable valve 40 at the second communication hole 121, the floating foam in the second sub-oil chamber 15 can be prevented from entering the first sub-oil chamber 14 by the movable valve 40 when the atomizer 100 is inverted.

In practice, it is found that when the air return passage 24 is connected to different auxiliary oil chambers, the speed and efficiency of conveying atomized liquid from the auxiliary oil chambers to the main oil chamber 13 during operation of the atomizer 100 are affected, particularly, when the air return passage 24 is connected to the auxiliary oil chamber at the downstream end (near the main oil chamber 13) of the flow path in the direction of the fluid flow path from the auxiliary oil chamber to the main oil chamber 13, the liquid in the auxiliary oil chamber at the upstream end (far from the main oil chamber 13) is difficult to flow in time to the main oil chamber 13, and the more the number of auxiliary oil chambers at the downstream end is, the more obvious is, in addition, after part of the liquid is consumed, the different auxiliary oil chambers form negative pressure chambers with different liquid levels, which causes the problem of nonuniform negative pressure inside, so that the liquid in the different auxiliary oil chambers cannot be fully utilized. The present inventors have found that the above-described problem can be solved by communicating the return passage 24 with a sub-oil chamber located at the upstream end of the fluid flow path among the plurality of sub-oil chambers (i.e., communicating the return passage 24 with a sub-oil chamber located away from the main oil chamber 13 on the fluid flow path).

Specifically, referring to fig. 5, in this embodiment, the first sealing member 20 has a clearance hole 23 corresponding to the position of the first auxiliary oil chamber 14, the movable valve 40 includes a rotating shaft 41 and a movable plate 42 pivotally connected to the middle part of the rotating shaft 41, the rotating shaft 41 is pivotally connected to the supporting member 30 at a position corresponding to the clearance hole 23, and the movable plate 42 can rotate around the axial direction of the rotating shaft 41 between an open position and a closed position. Thus, when the atomizer 100 is in the upright state, as shown in fig. 3, the movable plate 42 rotates about the axial direction of the rotation shaft 41 to the open position by gravity, and at this time the second communication hole 121 opens the first sub oil chamber 14 and the second sub oil chamber 15; when the atomizer 100 is in an inverted state, as shown in fig. 4, the movable plate 42 rotates around the axis direction of the rotary shaft 41 to a closed position under the action of gravity, at this time, the movable plate 42 is attached to the side of the second partition plate 12 facing the first auxiliary oil chamber 14, and the second communication hole 121 is blocked, so that the atomized liquid in the first auxiliary oil chamber 14 is prevented from entering the second auxiliary oil chamber 15 through the second communication hole 121, and the atomized liquid content in the second auxiliary oil chamber 15 is kept unchanged, thereby ensuring a good ventilation effect.

Further, the top end of the supporting member 30 is recessed to form a receiving space 32 corresponding to the position of the clearance hole 23, and when the movable valve 40 is in the open position, i.e. the atomizer 100 is in the upright state, the movable plate 42 falls down to be substantially horizontally received in the receiving space 32. The structure is beneficial to the assembly of the rotating shaft 41 and the supporting piece 30, and prevents the falling movable plate 42 from affecting the flow of atomized liquid.

In other embodiments, the movable valve 40 may be configured to slide up and down, that is, the support 30 is provided with a chute for accommodating the movable valve 40, and when the atomizer 100 is in the inverted state, a portion of the movable valve 40 slides out of the chute and blocks the second communication hole 121.

In one embodiment, the top surface of the first sealing member 20 is gradually raised from one end close to the main oil chamber 13 to one end far away from the main oil chamber 13, that is, the bottom surfaces of the first auxiliary oil chamber 14 and the second auxiliary oil chamber 15 are inclined structures inclined downwards towards the main oil chamber 13, so that atomized liquid in the first auxiliary oil chamber 14 and the second auxiliary oil chamber 15 can flow to the main oil chamber 13 to the greatest extent and then be heated and atomized by the atomizing assembly 50, the situation that excessive residual oil is effectively reduced but smooth suction cannot be achieved, and the number of suction ports of a user is increased.

Further, the included angle between the inclined plane and the horizontal plane is smaller than 90 ° and may be 5 °, 10 °, 15 ° or 20 °, so long as the air return port 21 on the first sealing member 20 is higher than the communication hole between the main oil chamber 13 and the auxiliary oil chamber, so that the air bubbles generated at the air return port 21 can be prevented from entering the first auxiliary oil chamber 14 and even the main oil chamber 13 to the maximum extent, so that the air bubbles generated at the air return port 21 are remained in the second auxiliary oil chamber 15 as much as possible, and the pressure difference exists between the first auxiliary oil chamber 14 and the second auxiliary oil chamber 15 all the time to consume the atomized liquid in the second auxiliary oil chamber 15 preferentially.

Specifically, as shown in fig. 5 and 6, the support member 30 is provided with an air return groove 31, the air return groove 31 cooperates with the first sealing member 20 to form the air return channel 24 together, and one end of the air return groove 31 extends into the air return port 21; the first sealing member 20 further includes a shielding portion 22, where the shielding portion 22 is located at the air return port 21, and one end of the shielding portion 22 is connected to one side of the air return port 21, and the other end of the shielding portion extends to cover the port of the air return channel 24 (i.e. the portion of the air return groove 31 exposed in the air return port 21). Therefore, the shielding part 22 is arranged at the air return port 21 to play a role of a one-way valve, and when the atomizer 100 is in a normal state, the shielding part 22 is stuck on the support piece 30 under the hydraulic action to block the air return channel 24, so that leakage is avoided; and when the atomizer 100 is in the suction state, the negative pressure formed in the auxiliary oil cavity can enable the external air to enter the second auxiliary oil cavity 15 so as to balance the air pressure of the second auxiliary oil cavity 15 and the external atmosphere, so that the oil discharging of the atomizer 100 is smoother, and the condition that the atomization assembly 50 is dry-burned due to insufficient oil supply is avoided.

In addition, in this embodiment, the air return port 21 is set higher than the second communication hole 121, according to the liquid pressure formula p=pgh, where ρ represents the density of the liquid, g represents the gravity acceleration, h represents the liquid depth, and the atomizer 100 preferentially consumes the atomized liquid in the second auxiliary oil chamber 15 during use, so that the corresponding depth at the air return port 21 becomes smaller, according to the pressure formula, the pressure at the air return port 21 is smaller, the force required when the shielding portion 22 is opened relative to the air return channel 24 (i.e., the check valve is opened) during air return is smaller, and air return is smoother, thereby avoiding the problem of sticking with a core.

In one embodiment, as shown in fig. 2 and 3, the bottom end of the oil cup 10 protrudes downward along the edge of the main oil chamber 13 to form a mounting tube 17, and the atomization assembly 50 is mounted in the mounting tube 17 and is connected with the inner wall of the main oil chamber 13 in a sealing manner, so as to enclose the main oil chamber 13 together with the oil cup 10.

Wherein, the second sealing member 51 is provided with a lower oil port 511, the atomizing bracket 52 is provided with a lower oil channel communicated with the lower oil port 511, and the other end of the lower oil channel away from the lower oil port 511 is communicated with the heating component 53, so that atomized liquid in the main oil cavity 13 can be guided to the heating component 53 through the lower oil channel, and the atomized liquid is heated and atomized by the heating component 53 to generate aerosol.

In the present embodiment, the top surface of the second seal member 51 serves as the bottom wall of the main oil chamber 13 and is lower than or flush with the bottom wall of the first communication hole 111, so that the lower oil port 511 is lower than the first communication hole 111, so that the atomized liquid stored in the auxiliary oil chamber can smoothly flow into the main oil chamber 13 and into the atomizing assembly 50 to contact the heating assembly 53.

The base 54 is propped against and fixed at the bottom end of the atomizing bracket 52 and is provided with an air inlet channel communicated with the atomizing cavity, one end of the air inlet channel away from the atomizing cavity is communicated with a cavity where the microphone switch 204 is positioned, and is directly or indirectly communicated with the outside of the shell 201; thus, when the user sucks, the microphone switch 204 senses the change of the air flow to trigger a signal, the control circuit board 205 controls the power supply 203 to supply power to the atomizing assembly 50, so that the heating assembly 53 is electrified to generate heat to generate aerosol, and at the same time, the air outside the housing 201 enters the atomizing cavity through the air inlet channel to be mixed with the generated aerosol, and then is output by the air guide pipe 162 and sucked by the user through the air suction hole 161.
