[0027] Please refer toFigures 1-6 The utility model embodiment provides a kind of atomizer, including atomizing core 6, at least two oil reservoirs that communicate with external atmosphere and communicating vessel 4;Each oil reservoir is independently arranged along transverse direction, and oil reservoir is communicated in series by communicating vessel 4, and the inlet end and the outlet end of communicating vessel 4 respectively extend in corresponding oil reservoir along longitudinal direction bottom end;Including one main oil reservoir 1 and one or more auxiliary oil reservoirs in multiple oil reservoirs, main oil reservoir 1 is in liquid communication with atomizing core 6, and main oil reservoir 1 and at least one auxiliary oil reservoir are directly communicated by communicating vessel 4;Wherein, in the communicating vessel 4 that is connected in series between two oil reservoirs, in the flow direction of liquid from auxiliary oil reservoir to main oil reservoir 1, the outlet end of communicating vessel 4 is lower than the inlet end in height direction.

[0028] In the utility model embodiment, at least two oil reservoirs are provided, and the oil reservoirs can be independently arranged along the transverse direction, and the oil reservoirs can be connected in series by the communicating vessel 4. In the multiple oil reservoirs, there is one main oil reservoir 1, and the main oil reservoir 1 is in liquid communication with the atomizing core 6. Therefore, the atomizing liquid in the main oil reservoir 1 can be directly heated and atomized by the atomizing core 6, that is, the atomizing liquid in the main oil reservoir 1 will be consumed.

[0029] In addition, the main oil reservoir 1 can be directly communicated with at least one auxiliary oil reservoir through the communicating vessel 4. Moreover, along the liquid flow direction from the auxiliary oil reservoir to the main oil reservoir 1 (that is, the outlet end of the corresponding communicating vessel 4 is connected to the main oil reservoir 1, and the inlet end is connected to the auxiliary oil reservoir), the outlet end of the corresponding communicating vessel 4 is lower than the inlet end in the height direction. That is to say, there is a height difference between the outlet end and the inlet end of the communicating vessel 4 connected in series between the main oil reservoir 1 and the auxiliary oil reservoir. Therefore, when the atomizing liquid in the main oil reservoir 1 is continuously consumed, the liquid level in the main oil reservoir 1 starts to drop, and there is a height difference between the liquid levels of the main oil reservoir 1 and the auxiliary oil reservoir. Moreover, the oil reservoirs communicate with the external atmosphere. Therefore, there will be a pressure difference between the outlet end and the inlet end of the communicating vessel 4 between the main oil reservoir 1 and the auxiliary oil reservoir. Under the driving of the pressure difference, the atomizing liquid in the auxiliary oil reservoir will flow to the main oil reservoir 1 through the communicating vessel 4, so that the liquid column heights of the main oil reservoir 1 and the auxiliary oil reservoir can be maintained, and the gas-liquid balance can be achieved. In this way, the main oil reservoir 1 can be automatically replenished with liquid. In addition, by dividing the large-capacity oil reservoir into multiple oil reservoirs for storing liquid, the technical problem of serious liquid leakage of the large-capacity oil reservoir can be avoided, and the influence of the changes in physical parameters (such as temperature, concentration, etc.) of the atomizing liquid in the main oil reservoir 1 on the atomizing liquid in the auxiliary oil reservoir during the atomization process can be avoided, and the problems of attenuation and change in flavor before and after the large-capacity flavor can be minimized.

[0030] In some embodiments, the multiple oil reservoirs can be arranged in a straight line array in the transverse direction. At this time, the main oil reservoir can be provided with auxiliary oil reservoirs on both sides or one side. Moreover, in some implementations, another auxiliary oil reservoir can be provided on the side of the auxiliary oil reservoir away from the main oil reservoir.

[0031] In some embodiments, a plurality of sub-oil tanks are arranged around the outer periphery of the main oil tank. For example, the plurality of sub-oil tanks can be arranged in a radial shape with the main oil tank as the center. In some implementations, another sub-oil tank can also be arranged on the side of the main oil tank away from the main oil tank. For example, the plurality of sub-oil tanks can be arranged on a plurality of concentric circles with the main oil tank as the center.

[0032] In some embodiments, the plurality of sub-oil tanks can also be arranged in an arc shape connected to the main oil tank.

[0033] Further, referring to Figures 1-3 In some embodiments, each oil tank is provided with a gas return structure 5 for communicating with the external atmosphere.

[0034] In some specific embodiments, the gas return structure 5 can be arranged at the end of the oil tank opposite to the bottom end of the oil tank (i.e., the top end of the oil tank). By arranging the gas return structure 5, the oil tank can be connected to the atmosphere, preventing the oil tank from being unable to supply liquid due to insufficient pressure. By arranging the gas return structure 5 in each oil tank, the gas-liquid balance between the oil tanks can be achieved through the communicating device 4, so that the atomized liquid in the sub-oil tank can be continuously supplemented to the main oil tank 1 for heating and atomization.

[0035] In other embodiments, the gas return structure 5 can be arranged on one side of the oil tank in the first direction, which is perpendicular to the longitudinal direction and perpendicular to the transverse direction.

[0036] In addition, it can be understood that the height direction is the longitudinal direction, and the transverse direction can be the length direction or the width direction; correspondingly, the first direction can be the width direction or the length direction. For example, Figure 2 and Figure 3 As shown in the drawings, the direction parallel to the Z-axis is the longitudinal direction, the direction parallel to the X-axis is the transverse direction, and the direction parallel to the Y-axis is the first direction.

[0037] Further, referring to Figures 1-3 In some embodiments, the gas return structure 5 includes a through hole formed in the oil tank and a one-way valve arranged in the through hole, or a waterproof and breathable film covering the through hole.

[0038] In some embodiments, referring to Figures 1-3 The gas return structure 5 of each oil tank can be a one-way valve. By arranging the one-way valve, the gas flow can flow between the outside and the oil tank, but the atomized liquid in the oil tank cannot flow outwards, thereby preventing the atomizer from leaking liquid. In addition, when the atomized liquid in the oil tank is consumed, the oil tank can be refilled through the one-way valve, realizing the repeated use of the atomizer.

[0039] In some embodiments, referring to Figures 1-3, the back gas structure 5 of each oil tank can be a waterproof air-permeable film. By setting a waterproof air-permeable film, the gas flow can flow in the outside and the oil tank, but the atomized liquid in the oil tank will not flow to the outside, thereby preventing the atomizer from leaking. In addition, when the atomized liquid in the oil tank is consumed, the waterproof air-permeable film can be removed, so that the through hole is in an open state, oil is injected into the oil tank through the through hole, and then the waterproof air-permeable film covers the through hole, realizing the repeated use of the atomizer.

[0040] In some embodiments, referring to Figures 1-3 , the back gas structure 5 of part of the oil tank is a one-way valve, and the back gas structure 5 of part of the oil tank is a waterproof air-permeable film. The air-permeable liquid-blocking of the oil tank and the repeated use of the atomizer can also be achieved.

[0041] Further, in some embodiments, the bottom end of the main oil tank 1 is lower than the bottom end of the auxiliary oil tank in the height direction; and / or, the bottom end of each auxiliary oil tank gradually decreases in the height direction along the flow direction of the liquid from the auxiliary oil tank to the main oil tank 1.

[0042] Specifically, between the main oil tank 1 and the adjacent auxiliary oil tank, the port of the tube mouth of the main oil tank 1 (i.e. the port of the outlet end) is lower than the port of the tube mouth of the auxiliary oil tank (i.e. the port of the inlet end) in the height direction, so that by setting the bottom end of the main oil tank 1 to be lower than the bottom end of the auxiliary oil tank in the height direction, the atomized liquid in the auxiliary oil tank can be completely absorbed by the main oil tank 1, thereby reducing the residual amount of the auxiliary oil tank.

[0043] Further, in some embodiments, in addition to setting at least one auxiliary oil tank to directly communicate with the main oil tank through the communication device 4, a plurality of auxiliary oil tanks can be set to be connected in series through the communication device 4. And the communication device 4 connected between two adjacent auxiliary oil tanks is lower than the inlet end in the height direction along the flow direction of the liquid from the auxiliary oil tank far away from the main oil tank 1 to the auxiliary oil tank close to the main oil tank 1 (also the flow direction of the liquid from the auxiliary oil tank to the main oil tank), so that when the atomized liquid in the main oil tank 1 is consumed and the atomized liquid in the auxiliary oil tank close to the main oil tank 1 is reduced, the auxiliary oil tank far away from the main oil tank 1 can supplement the atomized liquid for the auxiliary oil tank close to the main oil tank 1 due to the driving of the pressure difference. It can be understood that the liquid in the auxiliary oil tank close to the main oil tank 1 will supplement the atomized liquid for the main oil tank 1 along the same liquid flow direction, and finally the gas-liquid balance of each oil tank can be achieved.

[0044] In the two adjacent sub-oil tanks, the pipe opening of the communication device 4 near the sub-oil tank of the main oil tank 1 (i.e. the port of the outlet end) is lower than the pipe opening of the sub-oil tank far from the main oil tank 1 (i.e. the port of the inlet end) in the height direction. And along the flow direction of the liquid, the bottom end of the sub-oil tank gradually decreases in the height direction, i.e. the bottom end of the sub-oil tank near the main oil tank 1 is lower than the bottom end of the sub-oil tank far from the main oil tank 1 in the height direction, so that the atomized liquid in the sub-oil tank far from the main oil tank 1 can be completely sucked away by the sub-oil tank near the main oil tank 1, and thus the atomized liquid in each sub-oil tank can finally flow to the main oil tank 1, and the residual amount of each sub-oil tank can be reduced.

[0045] Further, referring to Figures 2-3 , the pipe opening of the communication device 4 and the bottom end of each oil tank have a gap, so that the atomized liquid can flow from one oil tank to the communication device 4 and then to another oil tank. And the gap between the different pipe openings of different communication devices 4 and the bottom end of the corresponding oil tank can be the same or different, as long as the pipe opening of the communication device 4 has a height difference.

[0046] Further, referring to Figures 2-3 , in some embodiments, the communication device 4 is provided with a porous material.

[0047] Specifically, the porous material can be directly provided in the communication device 4, so that the communication device 4 can form a capillary suction force on the liquid, and through the combined action of the capillary suction force and the pressure difference, the communication device 4 can better suck the atomized liquid from the sub-oil tank.

[0048] Further, referring to Figures 2-3 , in some embodiments, the communication device 4 includes a first communication part extending in the longitudinal direction, a second communication part extending in the longitudinal direction and arranged transversely to the first communication part, and a curved part connected between the first communication part and the second communication part; between the two adjacent oil tanks, the first communication part is located in one of the oil tanks, and the second communication part is located in the other oil tank; the end of the first communication part away from the curved part is the outlet end, and the end of the second communication part away from the curved part is the inlet end; the second communication part is provided with a porous material.

[0049] Specifically, between the main oil tank 1 and the adjacent auxiliary oil tank, the first communicating part (corresponding to the outlet end) of the communicating device 4 is located in the main oil tank 1 and the second communicating part (corresponding to the inlet end) is located in the auxiliary oil tank; between the adjacent two auxiliary oil tanks, the liquid flows from the auxiliary oil tank far away from the main oil tank 1 to the auxiliary oil tank close to the main oil tank 1, and the first communicating part (corresponding to the outlet end) of the communicating device 4 is located in the auxiliary oil tank close to the main oil tank 1 and the second communicating part (corresponding to the inlet end) is located in the auxiliary oil tank far away from the main oil tank 1. So that under the action of the pressure difference, the flow direction of the atomized liquid can be: from the auxiliary oil tank far away from the main oil tank 1 to the auxiliary oil tank close to the main oil tank 1; from the auxiliary oil tank to the main oil tank 1. Therefore, along the flow direction of the atomized liquid, between the adjacent two oil tanks, the atomized liquid in the oil tank first flows in the second communicating part from the nozzle (corresponding to the inlet end) of the second communicating part in the longitudinal direction, passes through the bending part, flows in the first communicating part in the longitudinal direction, and finally flows to another oil tank from the nozzle (corresponding to the outlet end) of the first communicating part. And by providing a porous material in the second communicating part, the second communicating part has a capillary suction to the atomized liquid in the oil tank, which better absorbs the atomized liquid in the oil tank, and the first communicating part is not provided with a porous material, so that the first communicating part does not have a capillary suction to the atomized liquid, and the atomized liquid in the first communicating part can directly flow to the oil tank, so that the first communicating part does not remain atomized liquid. By such arrangement, the capillary suction and the action of the pressure difference can be more fully utilized, so that the atomized liquid can better flow from the auxiliary oil tank to the main oil tank 1.

[0050] Further, referring to Figure 4 , the nozzle of the communicating device 4 extends in the first direction, and / or the communicating device 4 comprises a plurality of capillary tubes communicating between the adjacent two oil tanks, and the plurality of capillary tubes are arranged in the first direction; the first direction is perpendicular to the transverse direction and perpendicular to the longitudinal direction; or, the nozzle of the communicating device 4 is circular, and / or the communicating device 4 comprises a plurality of capillary tubes communicating between the adjacent two oil tanks, and the plurality of capillary tubes are arranged in the first direction; the first direction is perpendicular to the transverse direction and perpendicular to the longitudinal direction.

[0051] In some embodiments, referring to Figure 5 , the communicating device 4 can be a U-shaped tube, and the cross-sectional shape of the communicating device 4 in the longitudinal direction can be U-shaped. The nozzles of the communicating devices 4 can all extend in the first direction. Illustratively, the nozzles of the communicating devices 4 can be in the shape of a racetrack, so as to increase the contact area between the nozzles of the communicating devices 4 and the atomized liquid in the oil tank, and under the action of the pressure difference, the communicating devices 4 can absorb more atomized liquid from the auxiliary oil tank to the main oil tank 1.

[0052] In some embodiments, referring to Figure 6 , the communicating device 4 can be a U-shaped tube. The nozzles of the communicating devices 4 can be circular. Under the action of the pressure difference, the atomized liquid can be absorbed from the auxiliary oil tank to the main oil tank 1 through the communicating device 4.

[0053] In some embodiments, one communication device 4 can be formed by a plurality of capillary tubes, which can be in U shape, and the plurality of capillary tubes can be arranged in a first direction. The capillary tubes can have capillary attraction to the atomized liquid, and the capillary attraction and the pressure difference can work together to facilitate the atomized liquid to flow from the auxiliary oil tank to the main oil tank 1.

[0054] It can be understood that in some embodiments, the communication devices 4 can be different. For example, in a plurality of communication devices 4, the openings of some communication devices 4 can be circular, and some communication devices 4 can be formed by capillary tubes.

[0055] In addition, for example, the communication devices 4 with circular openings and track-shaped openings can be provided with porous materials.

[0056] Further, please refer to Figure 2 In some specific embodiments, the atomizer includes a main oil tank 1, a first auxiliary oil tank 2, a second auxiliary oil tank 3, and two communication devices 4. The main oil tank 1, the first auxiliary oil tank 2, and the second auxiliary oil tank 3 are arranged in a transverse direction in sequence. Between the main oil tank 1 and the first auxiliary oil tank 2, one communication device 4 has an inlet end connected to the first auxiliary oil tank 2 and an outlet end connected to the main oil tank 1. Between the first auxiliary oil tank 2 and the second auxiliary oil tank 3, the other communication device 4 has an inlet end connected to the second auxiliary oil tank 3 and an outlet end connected to the first auxiliary oil tank 2.

[0057] Specifically, the atomizer includes three oil tanks, and for example, the main oil tank 1, the first auxiliary oil tank 2, and the second auxiliary oil tank 3 are arranged in sequence from right to left. The flow direction of the atomized liquid is from left to right. In this case, one communication device 4 has an inlet end on the left side and an outlet end on the right side, and the other communication device 4 has an inlet end on the left side and an outlet end on the right side. When the main oil tank 1 consumes the atomized liquid, the atomized liquid in the first auxiliary oil tank 2 flows to the right to supplement the main oil tank 1, and the atomized liquid in the second auxiliary oil tank 3 also flows to the right to supplement the first auxiliary oil tank 2, so that the liquid columns in the three oil tanks are finally at the same height, and the gas-liquid balance is achieved.

[0058] Further, please refer to Figure 3 In some specific embodiments, the atomizer includes a main oil tank 1, a first auxiliary oil tank 2, a second auxiliary oil tank 3, and two communication devices 4. The first auxiliary oil tank 2, the main oil tank 1, and the second auxiliary oil tank 3 are arranged in a transverse direction in sequence. Between the main oil tank 1 and the first auxiliary oil tank 2, the opening of the communication device 4 connected to the main oil tank 1 is lower than the opening of the communication device 4 connected to the first auxiliary oil tank 2 in the height direction. Between the main oil tank 1 and the second auxiliary oil tank 3, the opening of the communication device 4 connected to the main oil tank 1 is lower than the opening of the communication device 4 connected to the second auxiliary oil tank 3 in the height direction.

[0059] Specifically, the atomizer comprises three oil tanks. Taking the example of the first auxiliary oil tank 2, the main oil tank 1, and the second auxiliary oil tank 3 arranged in sequence from right to left, the flow direction of the atomized liquid is from right to left, i.e. from the first auxiliary oil tank 2 to the main oil tank 1. In this case, the inlet end of one of the communicating vessels 4 is located on the left side and the outlet end is located on the right side. The flow direction of the atomized liquid is also from left to right, i.e. from the second auxiliary oil tank 3 to the main oil tank 1. In this case, the inlet end of the other communicating vessel 4 is located on the right side and the outlet end is located on the left side. When the main oil tank 1 consumes the atomized liquid, the atomized liquid in the first auxiliary oil tank 2 flows to the left and flows to the main oil tank 1. The atomized liquid in the second auxiliary oil tank 3 flows to the right and flows to the main oil tank 1. Finally, the liquid columns of the three oil tanks are at the same height, and the gas-liquid balance is achieved.

[0060] It can be understood that, in other embodiments, the atomizer can comprise two oil tanks, four oil tanks, five oil tanks, etc. In some implementations, a plurality of auxiliary oil tanks can be directly connected to the main oil tank 1 through the communicating vessels 4, and the flow direction of the atomized liquid is from the auxiliary oil tank to the main oil tank 1. In some implementations, a plurality of oil tanks are arranged in sequence along the transverse direction, i.e. auxiliary oil tanks are arranged on both sides or one side of the main oil tank 1, and the side of the auxiliary oil tank away from the main oil tank 1 can also be connected to the main oil tank 1. The flow direction of the atomized liquid can include from the auxiliary oil tank to the main oil tank 1, and from the auxiliary oil tank away from the main oil tank 1 to the auxiliary oil tank close to the main oil tank 1. Finally, the gas-liquid balance of each oil tank is achieved. The arrangement of the oil tanks can be diverse, and will not be described here in detail, but the flow direction of the atomized liquid always follows from the auxiliary oil tank to the main oil tank 1, and from the auxiliary oil tank away from the main oil tank 1 to the auxiliary oil tank close to the main oil tank 1. Finally, the gas-liquid balance of each oil tank is achieved.

[0061] Further, please refer to Figures 2-3 In some specific embodiments, the main oil tank 1 is provided with a mounting structure, and the atomizing core 6 is fixedly assembled to the mounting structure and contacts the atomized liquid of the main oil tank 1.
