Referring to fig. 1, 2, 3, 4, 5, 6 and 7, the present application provides an atomizing assembly 11 including an atomizing part 100 and a gas passing part 200. Specifically, the atomization portion 100 is substantially hollow and tubular, and an atomization cavity 110 is formed through the atomization portion 100 along its axial direction, and the atomization portion 100 is used for contacting an atomization medium and transferring the atomization medium in the atomization portion 100. The atomizing area 100 may be a cylindrical tube, an elliptical tube, a cubic tube, etc., and the shape of the substrate is described herein for clarity of the solution and is not a limitation on the specific shape of the atomizing area 100. The air passing part 200 is connected to the outer peripheral surface of the atomizing part 100, an air passing channel 210 parallel to the atomizing chamber 110 is formed through the air passing part 200, the air passing channel 210 is separated from the atomizing chamber 110 by the air passing part 200, and the air passing part 200 is used for blocking the transmission of the atomizing medium into the air passing channel 210. Herein, the atomizing medium may refer to a material capable of transferring and supplying a volatile component, such as smoke or the like, through the atomizing part 100.

Traditional electron cigarette's atomizing core is difficult to be ventilated when atomizing medium such as tobacco tar blocks up, and then the inside miaow head of electron cigarette can't detect the air current change when the user smokes, then atomizing core can't work. Compared with the conventional electronic cigarette, the atomization assembly 11 of the present application at least has the following beneficial effects:

firstly, an air passing part 200 is additionally arranged outside the atomizing part 100, and an air passing channel 210 is also arranged on the air passing part 200; after the atomizing area 100 contacts the atomizing medium, the atomizing medium can be delivered into the atomizing chamber 110, so that the atomizing medium is atomized to form an aerosol for suction; because the gas passing part 200 can block the transmission of the atomized medium, the atomized medium is difficult to be transmitted from the atomizing part 100 to the gas passing part 200, and the transmission of the atomized medium to the gas passing channel 210 can be avoided, so that the possibility that the gas passing channel 210 is blocked by the atomized medium is effectively reduced; under more extreme conditions, even if the atomizing chamber 110 is blocked due to excessive atomizing media in the atomizing chamber 110, the air passage 210 can be kept in a conducting state, so that the equipment can always detect the change of the air flow through the air passage 210 when a user sucks, the atomizing assembly 11 can start to work when the change of the air flow is detected, and meanwhile, the atomizing media blocked and accumulated in the atomizing chamber 110 are atomized, so that the atomizing chamber 110 is conducted again;

Specifically, in some embodiments, the atomizing area 100 is made of a porous material having a certain porosity, the gas passing portion 200 is made of a non-porous material or a porous material having a certain porosity, and the porosity of the gas passing portion 200 is lower than the porosity of the atomizing area 100. For example, the gas passing part 200 is made of a non-porous material, and the atomization part 100 is made of a porous material having a certain porosity. For another example, the gas passing portion 200 and the atomizing portion 100 are made of a porous material having a certain porosity, and the porosity of the gas passing portion 200 is lower than that of the atomizing portion 100.

It is understood that the atomizing area 100 is made of a porous material, and an atomizing medium such as tobacco tar can be permeated into the atomizing area for transmission. The air passing portion 200 is made of a non-porous material or a porous material with low porosity, so that the atomization medium such as smoke and oil is difficult to penetrate, that is, the air passing portion 200 is connected with the atomization portion 100, and the atomization medium is difficult to transfer from the atomization portion 100 to the air passing portion 200, so that the atomization medium absorbed by the atomization portion 100 is prevented from entering the air passing channel 210 of the air passing portion 200. In addition, the advantages of such an arrangement include that the porosity of the gas passing portion 200 is low, and the compressive strength is higher, so that the structural strength of the whole atomization assembly 11 can be obviously enhanced, and the assembly of the product is convenient.

The porous material may be ceramic, glass, or the like, and more specifically, the ceramic porous material may be preferably zirconia, silica, alumina, or the like. The porosity of the porous material of which the atomization portion 100 is made may range from 20% to 80%, and preferably, the porosity of the porous material of which the atomization portion 100 is made may range from 40% to 80%. The porosity of the porous material of the atomizing part 100 can be adjusted according to the components of the tobacco juice, for example, when the viscosity of the atomizing medium such as tobacco tar is high, the porous material with high porosity can be selected to make the atomizing part 100, so as to ensure the liquid guiding effect. The porosity of the gas passing portion 200 is preferably 20% or less, and in principle, it is considered that the lower the porosity of the gas passing portion 200, the better.

More specifically, in some of the embodiments, the gas passing part 200 is integrally sintered with the atomizing part 100. The atomizing part 100 and the gas passing part 200 are directly sintered into a whole, so that the structure is more reliable, the assembly efficiency is effectively improved, and the automatic production is facilitated. The sintering may refer to the mutual bonding of green solid particles of porous materials such as ceramics at high temperature, the growth of crystal grains, the gradual decrease of voids (air holes) and grain boundaries, the shrinkage of the total volume through the transfer of substances, the increase of density, and finally the formation of a dense polycrystalline sintered body with a certain microstructure. Wherein, the nonporous material and the porous material can be connected by adopting a sintering mode, no harmful substances are generated in the process, and the safety of the atomizing core can be ensured.

Referring to fig. 4, 7, 8, 10, 11 and 12, in some embodiments, the atomizing assembly 11 further includes an atomizing sleeve 300, and the atomizing sleeve 300 is sleeved on both the atomizing part 100 and the air passing part 200. Specifically, as shown in fig. 8, 10, 11 and 12, the tube wall of the atomizing sleeve 300 is opened with a feeding hole 310 therethrough, and the atomizing part 100 is at least partially exposed through the feeding hole 310 to contact with the atomizing medium.

The air passage 210 of the present application can be formed in various ways.

For example, as shown in fig. 2, 3 and 4, in some embodiments, the air passing channel 210 is formed by separately enclosing the air passing part 200. As described above, it is considered that the side peripheral wall of the air passage 210 is the main structure 12 of the air passage 200, that is, the air passage 200 is interposed between the air passage 210 and the atomization portion 100, that is, the atomization portion 100 is not exposed to the air passage 210, and the atomization medium contained in the atomization portion 100 is blocked by the air passage 200 and is hard to be introduced into the air passage 210.

As another example, as shown in fig. 5, fig. 6 and fig. 7, in another embodiment, the atomizing assembly 11 further includes an atomizing sleeve 300, the atomizing sleeve 300 is sleeved on the atomizing part 100 and the air passing part 200, the outer circumferential surface of the air passing part 200 is axially penetrated and provided with a groove 211, the groove 211 is separated from the atomizing part 100 by the air passing part 200, the groove wall of the groove 211 and the inner circumferential surface of the atomizing sleeve 300 surround to form an air passing channel 210, and the inner circumferential surfaces of the air passing part 200 and the atomizing sleeve 300 are used for blocking the transmission of the atomizing medium to the air passing channel 210.

Referring to fig. 9, 10, 11 and 12, in some embodiments, a material guiding portion 120 is further disposed on a side of the atomizing portion 100 facing the feeding hole 310, and the material guiding portion 120 is used for contacting the atomizing medium to transfer the atomizing medium to the atomizing portion 100; the material guiding portion 120 and the atomizing portion 100 are made of porous material with certain porosity, and the porosity of the material guiding portion 120 is higher than the porosity of the atomizing portion 100. The atomizing part 100 and the material guiding part 120 made of porous material are in a 'porous' shape on a microscopic level, and atomized media such as tobacco tar can be transported inside the atomizing part through capillary action and the like. On one hand, the porosity of the material guiding portion 120 is higher, so that the speed of absorbing and conducting the atomized medium by the material guiding portion 120 is higher, that is, the material guiding portion 120 can increase the speed of transmitting the atomized medium to the atomizing portion 100, thereby avoiding the dry burning of the atomizing portion 100 due to insufficient atomized medium; on the other hand, the porosity of the atomizing part 100 is low, so that the conduction rate of the atomizing medium in the atomizing part 100 is reduced, and the situations of liquid leakage, blockage of the atomizing chamber 110 and the like caused by the too fast introduction of the atomizing medium into the atomizing chamber 110 can be avoided.

Specifically, as shown in fig. 9, 10, 11 and 12, in some embodiments, the material guide part 120 at least partially extends into the material inlet hole 310. The atomizing part 100 is connected with the material guiding part 120, and the material guiding part 120 extends into the material inlet 310 of the atomizing sleeve 300, so that the atomizing part 100 can be connected with the atomizing sleeve 300 through the material guiding part 120, which is helpful to enhance the sealing and firmness of the atomizing sleeve 300, the gas passing part 200 and the atomizing part 100, and is not easy to loosen and easier to assemble.

For example, as shown in fig. 10, in some embodiments, the material guide part 120 does not protrude from the outer circumferential surface of the atomizing sleeve 300, and the thickness of the material guide part 120 is smaller than that of the atomizing sleeve 300.

As another example, as shown in fig. 11, in some embodiments, a side of the material guide part 120 facing away from the atomizing part 100 is flush with an outer circumferential surface of the atomizing sleeve 300.

As another example, as shown in fig. 12, in some embodiments, an end of the material guiding portion 120 away from the atomizing portion 100 protrudes from an outer circumferential surface of the atomizing sleeve 300. When the outer circumferential surface of the atomizing sleeve 300 is filled with the atomizing medium, for example, when the storage bin storing the atomizing medium is disposed near the feeding hole 310 at the outer side of the atomizing sleeve 300, the material guiding portion 120 protruding out of the atomizing sleeve 300 is equivalent to directly extending into the atomizing medium, so that the contact area between the material guiding portion 120 and the atomizing medium can be increased, and the speed of absorbing and delivering the atomizing medium by the material guiding portion 120 is increased.

In some embodiments, the material guiding portion 120 fills the whole material inlet hole 310 in the cross section of the material inlet hole 310, i.e. the material guiding portion 120 covers the whole material inlet hole 310.

It should be understood that the number of the material inlet holes and the material guiding portion 120 is not limited in the present application.

For example, in some embodiments, the feeding hole 310 and the material guide part 120 may be provided as one each.

For another example, in other embodiments, the feeding holes 310 and the material guiding portion 120 may be provided in plural, and the material guiding portion 120 and the feeding holes 310 correspond to each other in number and position. More specifically, as shown in the embodiments of fig. 9, 10 and 11, two sides of the atomizing sleeve 300 are respectively provided with a feeding hole 310, and correspondingly, two sides of the atomizing part 100 are also respectively protruded to form a material guiding part 120, wherein one material guiding part 120 is protruded into one feeding hole 310, and the other material guiding part 120 is protruded into the other feeding hole 310.

For example, in another embodiment, the heat-generating body 400 is embedded in the inner peripheral surface of the atomizing chamber 110, that is, the heat-generating body 400 is not exposed in the atomizing chamber 110.
