The atomizer on the market at present generally includes shell body and atomizing core, is equipped with air inlet channel in the shell body, air outlet channel and is used for storing the stock solution storehouse of atomized liquid, and air inlet channel is linked together with air outlet channel and forms the air current passageway, and atomizing core generally includes interconnect's liquid and heat-generating body, and atomizing core installs on air current channel's circulation route and is linked together with the stock solution storehouse, and wherein, the material of liquid can be the cotton of leading oil, porous ceramic etc. that the heat-generating body can be metal heating wire, metal heating wire etc.. The atomization process of the atomizer is generally as follows: atomized liquid flows into the liquid guide body of the atomization core from the liquid storage bin, the atomized liquid is atomized under the heating effect of the heating body to form aerosol which can be sucked by a user, when the user sucks, air flow is formed on a flow path between the air inlet channel and the air outlet channel, the air flow is taken away when flowing through the heating body, and the aerosol finally flows out of the air outlet channel along with the air flow to the oral cavity of the user to be sucked by the user.

However, the following problems are common in the atomizers currently on the market:

1. because the liquid storage bin and the atomizing core are always in a communication state, the atomizing core is always in a saturated state due to continuous absorption of the atomized liquid, and then the atomized liquid in the atomizing core is easily leaked from the atomizing core due to factors such as change of external air pressure, shaking of the atomizer and the like in the long-distance transportation process of the atomizer, so that the problem of liquid leakage is caused;

2. when a user adopts a special gesture to perform suction, the atomizer is easy to cause dry combustion method, for example, when the user occasionally adopts an inverted gesture (a suction nozzle of the atomizer faces downwards) to perform suction, atomized liquid in the liquid storage bin is far away from the position where the liquid storage bin is communicated with the atomized core under the action of self gravity, so that the atomized liquid in the liquid storage bin is not contacted with the atomized core in the suction process, and when the single suction time of the user is too long, after the atomized liquid in the atomized core is consumed, the atomized core is easy to cause the problem of liquid shortage and dry combustion due to the fact that the atomized liquid in the liquid storage bin is not timely supplemented.

In the technical scheme of this embodiment, be provided with the liquid storage cavity 211 and hold the chamber 81 that separate each other and set up in the casing subassembly 1, be provided with baffle 5 between liquid storage cavity 211 and the chamber 81 that holds, be equipped with on the baffle 5 with the play liquid hole 51 that is linked together of liquid storage cavity 211, one side that baffle 5 is close to holding the chamber 81 is equipped with the bottom plate portion 52 that corresponds play liquid hole 51 and sets up, be equipped with the return air structure 521 on the bottom plate portion 52, go out liquid hole 51 and hold the chamber 81 and be linked together through return air structure 521, be provided with the stock solution 7 of being made by porous material in holding the chamber 81, the atomized liquid in the liquid storage cavity 211 is absorbed by stock solution 7 after flowing out from return air structure 521, stock solution 7 can reduce the mobility of atomized liquid, play a cushioning effect to the atomized liquid, and then can reduce the flow of the atomized liquid of leading into atomized core 6 in the unit time, make atomized core 6 be difficult to reach saturated state, thereby can reduce the risk that the atomizer takes place the weeping. And, after the stock solution body 7 absorbs the atomized liquid to the saturated state, because store certain atomized liquid in the stock solution body 7, therefore in the in-process that the user utilized the atomizer to suck and use, after the atomized liquid in the atomizing core 6 was consumed, the atomized liquid in the stock solution body 7 can be in time supplied to the atomizing core 6 through capillary action, even if the user adopts the posture of inverting to suck and use moreover, under the adsorption of the stock solution body 7, the atomized liquid can not escape from the stock solution body 7, so that the atomizing core 6 can obtain sufficient atomized liquid supply from the stock solution body 7 all the time, thereby can effectively reduce the risk that the atomizing core 6 is lack of liquid dry combustion.

In addition, in the technical solution of the present embodiment, the atomized liquid in the liquid storage cavity 211 is not directly led into the liquid storage body 7 through the through-type liquid outlet hole 51, but is led into the liquid storage body 7 after sequentially passing through the liquid outlet hole 51 and the air return structure 521, compared with the case that the atomized liquid in the liquid storage cavity 211 is directly led into the liquid storage body 7 by adopting the through-type liquid outlet hole 51, the atomizer provided in the embodiment is beneficial to further reducing the risk of liquid leakage of the atomizer by adding the bottom plate part 52 corresponding to the liquid outlet hole 51 and arranging the air return structure 521 on the bottom plate part 52, so that on one hand, the flow rate of the atomized liquid in the liquid storage cavity 211 for guiding the liquid storage body 7 can be slowed down, further the fluidity of the atomized liquid can be further reduced, and the atomized core 6 is more difficult to reach the saturated state; on the other hand, when the user uses the atomizer to suck the atomized liquid, the liquid storage body 7 continuously supplies the atomized liquid to the atomization core 6 and continuously absorbs the atomized liquid flowing out from the air return structure 521, when the atomized liquid in the liquid storage cavity 211 is reduced to a certain extent, the liquid storage cavity 211 forms a certain negative pressure relative to the outside due to the reduction of the atomized liquid, the atomized liquid in the liquid storage cavity 211 stops flowing out from the air return structure 521 until the negative pressure is eliminated, when the liquid storage cavity 211 forms the negative pressure, because the air pressure of the outside is greater than the air pressure in the liquid storage cavity 211, the outside air is led into the liquid storage cavity 211 through the air inlet channel 311, the atomization core 6, the liquid storage body 7, the air return structure 521 and the liquid outlet hole 51 in sequence to return air, so as to raise the air pressure in the liquid storage cavity 211 and eliminate the negative pressure formed by the liquid storage cavity 211, when the negative pressure in the liquid storage cavity 211 is eliminated, the atomized liquid in the liquid storage cavity 211 can normally flow out from the air return structure 521 and be led into the liquid storage body 7 for supplementing, and the air return structure 521 can slow down the speed of air return, so that the flow rate of the atomized liquid in the liquid storage cavity 211 to the liquid storage 7 in the sucking and using process can be slowed down, and the flow rate of the atomized liquid to the atomized core 6 can be further reduced, so that the flow rate of the atomized liquid to the atomized core 6 in the sucking and using process can be reduced (particularly, when a user sucks with force, a certain negative pressure is formed at the atomized core 6 when the high-speed air flow passes through the atomized core 6, so that if the air return speed is too fast, the pressure difference between the liquid storage cavity 211 and the atomized core 6 can be possibly caused to be too large, so that the liquid supply speed of the atomized liquid to the atomized core 6 is too high) to cause the atomized core 6 to generate a 'liquid spraying' phenomenon, thereby causing the risk of liquid leakage.

Further, referring to fig. 2, 4, 6, 8 and 9, in an exemplary embodiment of the present utility model, the air return structure 521 opened on the bottom plate portion 52 is an air return hole 5211, the air return holes 5211 are provided in plurality, the air return holes 5211 are arranged on the bottom plate portion 52 at intervals, the aperture of each air return hole 5211 is 0.2mm to 1mm, and if the aperture of the air return hole 5211 is D, the aperture D is 0.2mm to 1mm.

Further, in the concrete implementation, the number and the pore size of the air return holes 5211 can be flexibly set according to the number of the liquid outlet holes 51, for example, when the number of the liquid outlet holes 51 is small, the number of the air return holes 5211 on the corresponding bottom plate portion 52 can be appropriately increased, and the pore size of each air return hole 5211 can be appropriately increased or decreased in the range of 0.2mm to 1 mm; for another example, when the number of the liquid outlet holes 51 is large, the number of the air return holes 5211 on the corresponding bottom plate portion 52 may be appropriately reduced, and the aperture size of each air return hole 5211 may be appropriately increased or decreased in the range of 0.2mm to 1mm.

In the present embodiment, based on the above structural design, by providing the plurality of air return holes 5211 with the aperture of 0.2mm to 1mm on the bottom plate portion 52, the air return speed of the atomizer can be at a proper size in the process of the user sucking and using the atomizer, and the flow rate of the atomized liquid in the liquid storage cavity 211 to the liquid storage 7 can be at a proper size. So, not only can make the atomized liquid in the liquid storage body 7 in time obtain the replenishment after consuming for the user still has sufficient atomized liquid in the liquid storage body 7 to be used for supplying atomizing core 6 to atomize after carrying out many times in succession, thereby be favorable to further reducing the risk that the dry combustion method takes place for the atomized core 6 in the use, and the velocity of flow that makes the atomized liquid in the liquid storage body 7 to lead to atomizing core 6 can be in suitable size moreover, thereby be favorable to further reducing the risk that the atomized core 6 takes place "hydrojet" phenomenon and causes the weeping because of the atomized liquid velocity of flow that leads to atomizing core 6 is too fast in the suction use.

Further, referring to fig. 2, 4, 6, 10 and 11, in another exemplary embodiment of the present utility model, the air return structure 521 formed on the bottom plate portion 52 is an air return slit 5212, and the size of the air return slit 5212 is 0.2mm to 1mm, and if the size of the air return slit 5212 is L, L is 0.2mm to 1mm. In specific implementation, the air return slit 5212 of the present embodiment may be a slit structure in a shape of a "straight line", a slit structure in a shape of a "cross", or a slit structure in a shape of a "rice", as long as the use requirement can be satisfied, and the shape of the air return slit 5212 is not particularly limited in this embodiment. In addition, in some embodiments, the air return slits 5212 may be uniformly sized slit structures, for example, if the air return slits 5212 are in a shape of "one" then the air return slits 5212 have equal gap sizes at various positions along the extending direction of the air return slits 5212, and in this case, the vertical projection of the air return slits 5212 on the bottom plate 52 (i.e., the air return slits 5212 viewed from the top view) may be rectangular; in other embodiments, the air return slit 5212 may have a slit structure with uneven size, for example, if the air return slit 5212 is in a shape of a "straight line", the size of the air return slit 5212 at each position along the extending direction of the air return slit 5212 is gradually reduced, and the vertical projection of the air return slit 5212 on the bottom plate 52 may have a trapezoid, triangle or the like.
