The support member 1 is hollow, the top of the support member 1 is provided with an air inlet 12, and the air inlet 12 is communicated with the outside. Moreover, the side wall of the supporting member 1 is provided with a liquid inlet hole 14 and an air inlet hole 13, wherein the air inlet hole 13 is positioned above the liquid inlet hole 14. The liquid inlet hole 14 is used for allowing the atomized liquid in the atomizer to enter, and the air inlet hole 13 is used for allowing the gas entering the accommodating cavity 11 from the air inlet 12 to pass through the air inlet hole 13.

Referring to fig. 3 and 4, the liquid inlet holes 14 are provided with a plurality of groups, and the plurality of groups of liquid inlet holes 14 are uniformly distributed along the axial center circumference of the support member 1. In the present embodiment, four sets of the liquid inlet holes 14 are provided. The air inlet holes 13 are arranged above the liquid inlet hole 14, and in the embodiment, four groups of air inlet holes 13 are also arranged, and the four groups of air inlet holes 13 are uniformly distributed along the axial center circumference of the support member 1. In addition, in vertical projection, the positions of the liquid inlet hole 14 and the air inlet hole 13 are not overlapped, and the size of the air inlet hole 13 is smaller than that of the liquid inlet hole 14.

Referring to fig. 3 and 4, since the atomizing core is in the environment of the atomized liquid, the atomized liquid may enter the accommodating chamber 11 from the air inlet hole 13. In order to reduce the entrance of the atomized liquid of the atomizer into the atomizing core, in the present embodiment, an air intake shutter 4 is provided. The intake screen 4 is provided on the side wall of the support 1 and, furthermore, the intake screen 4 is located on the path of the gas through the intake holes 13. In addition, the air intake baffle 4 is made of an oil-absorbing and air-permeable material, such as a liquid-guiding cotton, a porous material made of porous ceramics, or a dense material with small holes. In this embodiment, a liquid guide surface or a liquid storage cotton or a fiber-based woven tube is preferably used. The aim at that sets up like this, the atomized liquid when the atomizer gets into the back from inlet port 13, at first can be absorbed by the shielding piece 4 that admits air, after the shielding piece 4 that admits air is soaked, the atomized liquid can form the oil film in inlet port 13 department, and the atomized liquid outside the inlet port 13 is in under the sealed environment in the stock solution piece this moment, thereby form sealed stock solution piece, along with the inside atomized liquid consumption of stock solution piece, the inside of stock solution piece can form the great cavity of pressure, this cavity forms negative pressure and negative pressure makes the liquid level of atomized liquid be located the below of inlet port 13, so, liquid is not in the seepage to inlet port 13.

Referring to fig. 4, the liquid guiding member 5 is further included, and the liquid guiding member 5 is used for guiding the atomized liquid entering the cavity from the liquid inlet hole 14 to the heat generating member 2. Specifically, the liquid guiding member 5 is disposed in the accommodating cavity 11, and the liquid guiding member 5 is located at one side of the liquid inlet hole 14. In the present embodiment, the liquid guiding member 5 is made of a multi-layer liquid guiding cotton sheet or porous ceramic or a combination of the two. In this embodiment, a multi-layer wicking cotton sheet is preferred, and the wicking element 5 has a porosity of between 30% and 80%, and a pore spacing of between 1 μm and 100 μm. In the present embodiment, the thickness of the intake shield 4 is within 2/3 of the thickness of the liquid guide 5.

The purpose of this arrangement is that the thickness of the baffle at the position of the air inlet hole 13 is smaller than that of the baffle at the position of the liquid inlet hole 14, so that the negative pressure of the external atomized liquid is reduced after the external atomized liquid is consumed. The gas entering from the air inlet 12 can preferentially break through the oil film at the air inlet 13, so that the gas enters the position of the external atomized liquid storage, and cannot enter from the position of the liquid inlet 14 at the thicker position. In addition, the horizontal height of the liquid inlet hole 14 is positioned below the air inlet hole 13, and the area of the liquid inlet hole 14 is also larger than that of the air inlet hole 13, so that the oil film pressure at the liquid inlet hole 14 is larger than that of the air inlet hole 13, and gas can only enter the position for storing atomized liquid from the air inlet hole 13. Therefore, only the atomized liquid can pass through the liquid inlet hole 14, and therefore the liquid inlet hole 14 serves only as a liquid inlet passage, thereby separating an inflow path of the external gas and an inflow path of the atomized liquid. The liquid guide piece 5 does not play a role of guiding external air, and the liquid guide piece 5 is only used for guiding atomized liquid, so that a good atomization effect is maintained; and is not affected by the usage of the atomized liquid in the liquid storage bin 100.

The implementation principle of an atomizing core in the embodiment of the application is as follows: the horizontal height of the liquid inlet hole 14 is positioned below the air inlet hole 13, and the area of the liquid inlet hole 14 is larger than that of the air inlet hole 13, so that the oil film pressure at the liquid inlet hole 14 is larger than that of the air inlet hole 13, and gas can only enter the position for storing atomized liquid from the air inlet hole 13. The liquid guide piece 5 does not play a role of guiding external air, and the liquid guide piece 5 is only used for guiding atomized liquid, so that a good atomization effect is maintained; and is not affected by the usage of the atomized liquid in the liquid storage bin 100. Therefore, only the atomized liquid can pass through the liquid inlet hole 14, and therefore the liquid inlet hole 14 serves only as a liquid inlet passage, thereby separating an inflow path of the external gas and an inflow path of the atomized liquid.

Example two:

referring to fig. 5 and 6, the atomizing core assembly comprises the atomizing core and further comprises a gas-liquid separating member 6.

Referring to fig. 7 and 8, the atomizing core is inserted into the gas-liquid separator 6, and the gas-liquid separator 6 is used to form a stable gas passage 7 and a stable liquid passage 8 from the gas inlet path and the liquid inlet path.

Referring to fig. 7 and 9, the gas-liquid separator 6 is provided with a through cavity 61, the atomizing core is arranged through the through cavity 61, and the side wall of the through cavity 61 is provided with a partition 62, and the partition 62 is used for partitioning the gas inlet 13 and the liquid inlet 14. Specifically, in the present embodiment, the partition 62 includes a first partition unit 621 and a second partition unit 622, and the liquid inlet gap 63 is formed between the first partition unit 621, the second partition unit 622, the outer wall of the atomizing core, and the wall of the through cavity 61. Atomized liquid can follow in the feed liquor clearance 63 gets into liquid passage 8, and atomized liquid flows into drain 5 from feed liquor hole 14 again, and drain 5 leads atomized liquid to piece 2 that generates heat to heat atomizing.

Referring to fig. 6, the number of the partitions 62 is set to be equal to the number of the liquid inlet holes 14, and four sets of the partitions 62 are provided in the present embodiment. The four sets of liquid inlet holes 14 are respectively positioned within the vertical projection range of the four different sets of partitions 62.

Referring to fig. 8 and 10, the sidewall of the through cavity 61 is further provided with a blocking portion 64, the blocking portion 64 is connected to the first partition unit 621 of one set of partitions 62 and the second partition unit 622 of the other set of partitions 62, and the blocking portion 64 is located above the air inlet hole 13. Therefore, when the atomized liquid enters the gas channel 7, the liquid level of the atomized liquid rises, and at the beginning, the atomized liquid can permeate to the air inlet shielding piece 4 through the air inlet hole 13, and after the air inlet shielding piece 4 is soaked, the atomized liquid with the lowered liquid level can form an oil film at the position of the air inlet hole 13; so that the end of the gas channel 7 forms a sealed space. Since the air pressure in the sealed space becomes large, the liquid level of the atomized liquid in the air channel 7 is driven to fall, that is, the air inlet 13 is located in the sealed space, and the atomized liquid is difficult to pass through the air inlet 13. When the atomized liquid is gradually consumed, the liquid level of the atomized liquid in the gas channel 7 is reduced, the air pressure of the sealed space is reduced, and the gas entering from the gas inlet 12 breaks through the oil film, so that the inside air and the outside air are communicated, and the outside air enters the liquid storage bin 100. At this time, the liquid surface of the atomized liquid in the gas passage 7 rises, and when the liquid surface of the atomized liquid continues to be positioned above the gas inlet hole 13, an oil film is formed, and the above-described process is repeated. When the liquid level of the atomized liquid is below the gas inlet hole 13, the gas penetrates the gas inlet hole 13 from the outside and enters the gas channel 7. Dynamic balance is realized in the whole process, and the outside gas can not disturb atomized liquid to enter the atomizing core, so that stable atomizing effect is maintained.

Referring to fig. 6 and 9, since the upper and lower sides of the first and

second partition units

621 and 622 in the partition portion 62 of the same group are not blocked by the blocking portions 64, when the atomized liquid enters the liquid passage 8, the air pressure does not change, the liquid level of the atomized liquid is only affected by consumption, and a good effect of the atomized liquid entering the atomizing core is maintained.

The embodiment of the application provides an implementation principle of an atomizing core assembly: when the atomized liquid enters the gas channel 7, the liquid level of the atomized liquid rises, and at the beginning, the atomized liquid can permeate to the air inlet shielding piece 4 through the air inlet hole 13, and after the air inlet shielding piece 4 is soaked, the atomized liquid with the lowered liquid level can form an oil film at the position of the air inlet hole 13; so that the end of the gas channel 7 forms a sealed space. Since the air pressure in the sealed space becomes higher, the liquid level of the atomized liquid in the air channel 7 is driven to drop, that is, the air inlet 13 is located in the sealed space, and the atomized liquid is difficult to pass through the air inlet 13. When the atomized liquid is gradually consumed, the liquid level of the atomized liquid in the gas channel 7 is reduced, the air pressure of the sealed space is reduced, and the gas entering from the gas inlet 12 breaks through an oil film, so that the inside air and the outside air are communicated. At this time, the liquid surface of the atomized liquid in the gas passage 7 rises, and when the liquid surface of the atomized liquid continues to be positioned above the gas inlet hole 13, an oil film is formed, and the above process is repeated. When the liquid level of the atomized liquid is below the gas inlet hole 13, the gas penetrates the gas inlet hole 13 from the outside and enters the gas channel 7. The whole process realizes dynamic balance. When the atomized liquid enters the liquid channel 8, the air pressure cannot change, and the liquid level of the atomized liquid is only influenced by consumption, so that the good effect of the atomized liquid entering the atomizing core is maintained; thereby realizing the effect of gas-liquid separation.

Therefore, the reservoir 100 is in a sealed state, and the atomized liquid in the reservoir 100 is subjected to the negative pressure of the sealed chamber.

Referring to fig. 11, in order to maintain a good liquid feeding effect, in the present embodiment, a distance is provided between the bottom wall of the atomizing core assembly and the upper surface of the atomizing core mounting base 10.
