The atomizer embodiment of the present utility model is preferably provided to be less than 2mm by setting the through-flow cross-sectional area of the communication hole 181 to be smaller than the through-flow cross-sectional area of the through-oil hole ² Thereby slowing down the speed of the atomized liquid in the auxiliary oil cavity when flowing to the main oil cavity 12, and further reducing the problem of snoring in the suction process; in addition, when the atomized liquid in the auxiliary oil cavity is supplemented into the main oil cavity 12, the external air of the atomizer 100 is supplemented into one or more auxiliary oil cavities through the air return channel 24, so that the cavity pressure of the auxiliary oil cavity is balanced with the external atmospheric pressure, the atomized liquid in the auxiliary oil cavity is preferentially consumed, the liquid level of the atomized liquid in the auxiliary oil cavity is lower, the pressure at the air return channel 24 is lower, ventilation is smoother, 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.

Specifically, a vertical partition plate 11 is formed in the oil cup 10 to partition the inner space of the oil cup 10 into a first oil storage space and a second oil storage space, a suction nozzle structure 16 is formed at the upper end of the oil cup 10 corresponding to the first oil storage space in a protruding manner, a suction hole 161 is formed at the top end of the suction nozzle structure 16, an air duct 162 extending into the first oil storage space is formed at the inner wall of the oil cup 10 in a protruding manner along the edge of the suction hole 161, the air duct 162 is communicated with an atomization cavity 522 in the atomization assembly 50, and aerosol generated by the atomization assembly 50 in the atomization cavity 522 can be sucked out from the air duct 162 and the suction hole 161 when a user sucks the aerosol.

A first partition part 18 is arranged between the outer wall of the air duct 162 and the inner wall of the first liquid storage space to partition the first liquid storage space into a main oil cavity 12 and a first auxiliary oil cavity 13, and a communication hole 181 is arranged at the bottom of the first partition part 18 to communicate the main oil cavity 12 with the first auxiliary oil cavity 13; a second partition 19 is formed in the second oil storage space to partition the second oil storage space into a second auxiliary oil chamber 14 and a third auxiliary oil chamber 15, the partition plate 11 is provided with a first oil passing hole 111 communicated with bottoms of the first auxiliary oil chamber 13 and the second auxiliary oil chamber 14, the second partition 19 is provided with a second oil passing hole 191 communicated with bottoms of the second auxiliary oil chamber 14 and the third auxiliary oil chamber 15, and the cross-sectional area of the first oil passing hole 111 is larger than that of the second oil passing hole 191. In the present embodiment, the air duct 162, the partition plate 11, the first partition portion 18, the second partition portion 19 and the oil cup 10 are integrally formed; it should be noted that the second partition 19 may be two or more, so as to partition the second oil storage space into a plurality of sub-oil chambers.

Preferably, 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 second auxiliary oil cavity 14 and the third auxiliary oil cavity 15 together with the oil cup 10, the top surface of the first sealing member 20 serves as the bottom wall of the second auxiliary oil cavity 14 and the third auxiliary oil cavity 15, a gap is formed at the bottom end of the second separating portion 19, the bottom end of the second separating portion 19 abuts against the top surface of the first sealing member 20, and the second oil passing hole 191 is formed together with the first sealing member 20 through the arrangement of the gap.

Referring to fig. 4 to 7, the first seal member 20 is provided with a return port 21 corresponding to the third sub-oil chamber 15, and a return passage 24 communicates with the return port 21. In this way, in the atomization process, the atomized liquid in the main oil chamber 12 is consumed, the atomized liquid in the first auxiliary oil chamber 13 is fed into the main oil chamber 12 through the communication hole 181, the atomized liquid in the second auxiliary oil chamber 14 is fed into the first auxiliary oil chamber 13 through the first oil passing hole 111, the atomized liquid in the third auxiliary oil chamber 15 is fed into the second auxiliary oil chamber 14 through the second oil passing hole 191, and since the flow cross-sectional area of the first oil passing hole 111 is larger than that of the second oil passing hole 191, the flow rate and flow rate of the atomized liquid in the second auxiliary oil chamber 14 flowing to the first auxiliary oil chamber 13 are faster than those of the atomized liquid in the third auxiliary oil chamber 15 flowing to the second auxiliary oil chamber 14, so that the cavity in the second auxiliary oil chamber 14 generates negative pressure, the flow rate of the atomized liquid in the second auxiliary oil chamber 14 flowing to the first auxiliary oil chamber 13 is slowed down, the overall oil dropping speed of the atomizer 100 is slowed down, and the probability of generating snoring is reduced.

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 12 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 12) of the flow path in the direction of the fluid flow path from the auxiliary oil chamber to the main oil chamber 12, the liquid in the auxiliary oil chamber at the upstream end (far from the main oil chamber 12) is difficult to flow in time to the main oil chamber 12, 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 liquid level in the different auxiliary oil chambers forms different negative pressure chambers, 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 12 on the fluid flow path).

In order to keep the air entering the air return passage 24 into the third auxiliary oil chamber 15 to the greatest extent possible, in this embodiment, the level of the air return port 21 is set to be higher than the level of the second oil passing hole 191, so as to avoid that the air return bubbles enter the second auxiliary oil chamber 14 through the second oil passing hole 191, and further avoid that the bubbles easily pass through the second auxiliary oil chamber 14 and the first auxiliary oil chamber 13 in turn and then flow into the main oil chamber 12 to affect the oil discharging speed.

Since the atomizer 100 may shake along with the movement of the user during the use process, the bubbles entering through the air return channel 24 may enter the second auxiliary oil chamber 14 or the first auxiliary oil chamber 13 or even the main oil chamber 12 from the third auxiliary oil chamber 15, if the air return bubbles enter the main oil chamber 12, the negative pressure in the main oil chamber 12 may be reduced, so that the oil discharging speed is increased, and further the problems of oil leakage and snoring are easy to occur.

Therefore, in order not to allow large bubbles entering through the return port 21 in the third auxiliary oil chamber 15 to easily enter the main oil chamber 12 forward, the present embodiment may provide the first oil passing hole 111 in a rectangular, circular, elliptical or like shape, as shown in fig. 8a, 8b and 8 c; the second oil passing hole 191 is formed in a flat trapezoid, semicircle, semi-ellipse, etc. shape as shown in fig. 9a, 9b, and 9 c; and the width of the second oil passing hole 191 in the vertical direction is smaller than that of the first oil passing hole 111, preferably smaller than 3mm. Further, the inner wall of the first oil passing hole 111 and/or the second oil passing hole 191 protrudes towards the center direction to form a sharp-tooth structure 112/192 for breaking the return air bubble, and the sharp-tooth structure 112/192 can divide the large air bubble into small air bubbles, so that the large air bubble cannot enter the auxiliary oil chamber in the direction close to the main oil chamber 12, and the influence of the excessive large air bubble moving towards the main oil chamber 12 on the negative pressure in the main oil chamber 12 is reduced. In this embodiment, the shapes of the first oil passing hole 111 and the second oil passing hole 191 may be the same or different, and the specific shape of the tine structure 112/192 is not limited, so as to satisfy the requirement that the tine structure 112/192 can easily divide large bubbles.

In order to make the bubbles generated by the air return port 21 unlikely to enter the second auxiliary oil chamber 14 through the second oil passing hole 191, the air return port 21 in this embodiment has a level higher than that of the second oil passing hole 191, for example, the first seal 20 protrudes upward to form a boss higher than that of the second oil passing hole 191 at a position corresponding to the third auxiliary oil chamber 15, and the air return port 21 is disposed on the top end of the boss.

In the present embodiment, the top surface of the first seal member 20 is provided to be gradually raised from the end near the main oil chamber 12 to the end far from the main oil chamber 12. That is, the bottom surface of the auxiliary oil chamber is a slope structure inclined downward toward the main oil chamber 12, and the included angle between the slope and the horizontal plane is smaller than 90 °, and may be 5 °, 10 °, 15 ° or 20 °, so long as the level of the air return opening 21 on the first sealing member 20 is higher than the level of the second oil passing hole 191, so as to reduce the possibility that the air bubbles generated at the air return opening 21 enter the second auxiliary oil chamber 14, so that the air bubbles generated at the air return opening 21 remain in the third auxiliary oil chamber 15 as much as possible, and a pressure difference exists between the main oil chamber 12 and other auxiliary oil chambers all the time to preferentially consume the atomized liquid in each auxiliary oil chamber.

In addition, the top surface of the first sealing member 20 is provided with an inclined surface structure, so that atomized liquid in the third auxiliary oil cavity 15 and the second auxiliary oil cavity 14 can flow to the first auxiliary oil cavity 13 to enter the main oil cavity 12 and then be heated and atomized by the atomizing assembly 50, the situation that excessive residual oil is generated and can not be pumped smoothly is effectively reduced, and the number of pumping ports of a user is increased.

In one embodiment, as shown in connection with fig. 5 to 7, the atomizer 100 further includes a support member 30 mounted in the bottom end of the first sealing member 20, the support member 30 is made of hard plastic and mounted in the bottom end of the first sealing member 20, the first sealing member 20 is provided with an air return port 21, an air return channel 24 is formed between the first sealing member 20 and the support member 30, one end of the air return channel 24 is communicated with the air return 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 easily subject to the problem of sagging during injection molding, the assembly with the first seal 20 and the sealing effect are affected, and the requirement for the accuracy of the oil cup 10 is reduced.

Specifically, in this embodiment, by forming the air return groove 31 on the supporting member 30, the air return groove 31 includes a first section 311 formed on the top surface of the supporting member 30, and a second section 312 formed on the side wall of the supporting member 30 and connected to the first section 311, and the air return groove 31 cooperates with the inner wall of the first sealing member 20 to form the air return channel 24; such a structural arrangement may facilitate the manufacture of the support 30.

Further, the bottom of the supporting member 30 is concavely formed with a receiving cavity 33, the sidewall of the supporting member 30 is provided with an air return hole 32 communicating the receiving cavity 33 and the second section 312, the receiving cavity 33 is internally provided with oil absorbing cotton 40, and the air return hole 32 is connected with the oil absorbing cotton 40. It should be noted that, in this embodiment, the accommodating cavity 33 is communicated with the inner cavity of the main body 200, and is indirectly communicated with the external air through the inner cavity of the main body 200, compared with the structure that the air return groove 31 is opened in the atomizing assembly 50 and/or the outer shell in the prior art, when the leakage condition occurs in the air return channel 24 in this embodiment, the leaked atomized liquid can be sucked away by the oil absorbing cotton 40, that is, the atomized liquid can be prevented from flowing to the electronic components such as the atomizing assembly 50 or the control circuit along the air return atomized liquid, the problem of oil explosion or the cracking of the outer shell is avoided, and the phenomenon of bad smell caused by insufficient oil supply due to condensation and plugging of the atomized liquid in the air return channel 24 can be prevented.

Wherein, the width of the air return groove 31 is smaller than the diameter of the air return hole 32, the width of the air return groove 31 is preferably smaller than 0.5mm, and the diameter of the air return hole 32 is smaller than 0.7mm; the oil absorbing cotton 40 is in interference fit with the accommodating cavity 33, the interference is 0.2mm, the two sides of the outer wall of the first sealing piece 20 corresponding to the second section 312 of the air return groove 31 are respectively provided with the convex ribs 23, and compared with the traditional air return groove 31, the structure has the advantages that the sealing among the supporting piece 30, the first sealing piece 20 and the inner wall of the oil cup 10 can be ensured, so that atomized liquid can only leak along the air return groove 31; and the interference fit between the oil absorbing cotton 40 and the inner wall of the accommodating cavity 33 can ensure that the air return groove 31 is not directly communicated with the atmosphere, and the air return in the suction process can be performed along the air return groove 31 through the oil absorbing cotton 40, so that the air return speed can be slowed down, the oil discharging speed is slowed down, and the problems of snoring and oil flying can be prevented.

Further, 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 external air to enter the auxiliary oil cavity so as to balance the air pressure of the auxiliary oil cavity 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.
