Background

The electronic atomizing device is a device capable of heating aerosol generating substrates to generate aerosol, and an atomizing core of the electronic atomizing device generally comprises a ceramic substrate and a heating body arranged on an atomizing surface of the ceramic substrate, and the heating body is electrified to heat the aerosol generating substrates near the atomizing surface.

The atomizing face generally includes a first atomizing area in which the heat generating body is located and a second atomizing area adjacent to the first atomizing area. The first atomization zone has the highest temperature and the strongest explosive force, and the aerosol generating substrate above the heating element has high supersaturation degree and can be atomized in maximized equal proportion. While the second atomization zone has a low atomization temperature, the low boiling point substances are preferentially atomized, so that unequal ratio atomization is unavoidable. Also, as the number of suction ports increases, low boiling point substances in the aerosol-generating substrate become smaller and smaller, which causes a problem of poor consistency of taste before and after suction.

Fig. 1 shows a schematic structural view of an atomizing core in an embodiment of the present utility model.

Referring to the drawings, the present utility model provides an atomizing core 100, which includes a base 10, a heating element 20, and a blocking body 30. The atomizing core 100 of the present disclosure heats the atomized aerosol-generating substrate upon energization to generate an aerosol. In particular, the atomizing core 100 of the present disclosure may be applied to an electronic atomizing device, wherein a liquid storage chamber within the electronic atomizing device is capable of providing an aerosol-generating substrate to the atomizing core 100 for atomizing to generate an aerosol.

The substrate 10 may be a porous substrate, such as porous alumina ceramic, porous silica, porous cordierite, porous silicon carbide, porous glass, porous silicon nitride, porous mullite, composite porous ceramic, composite porous glass, etc., but not limited thereto, and may be other materials suitable for molding and sintering. The molding mode of the porous matrix is not limited to casting molding, injection molding and dry pressing molding.

In particular, the porous matrix is in fluid communication with the reservoir and may wick the aerosol-generating substrate from the reservoir and/or force the aerosol-generating substrate into the porous matrix by gravity. The heater 20 heats the aerosol-generating substrate within the atomized porous substrate.

The base 10 has an atomizing surface 11, and the heating element 20 is provided on the atomizing surface 11, specifically, may be provided on the atomizing surface 11 of the base 10, or may be at least partially embedded in the base 10 from the atomizing surface 11.

The base 10 further has a liquid suction surface 12, and the liquid suction surface 12 may be provided so as to face the atomizing surface 11 or may not face the atomizing surface 11, and in short, the aerosol-generating substrate in the liquid storage chamber can enter the base 10 from the liquid suction surface 12, be guided to the atomizing surface 11, and be heated and atomized by the heating element 20.

The heating element 20 may be a heating sheet, a heating film, a heating mesh, or the like, and may be capable of heating the atomized aerosol-generating substrate.

Referring to fig. 2, in the embodiment of the present utility model, the region where the orthographic projection of the heating element 20 on the atomizing surface 11 is located forms a first atomizing area 111. It is understood that the orthographic projection of the heat generating body 20 on the atomizing surface 11 means the orthographic projection of the heat generating body 20 toward the heat generating body 20 in the direction perpendicular to the atomizing surface 11.

The atomizing face 11 further has a second atomizing area 112 disposed at the periphery of the first atomizing area 111, and the blocking body 30 is disposed at the second atomizing area 112 for blocking the aerosol-generating substrate from being atomized in the second atomizing area 112.

Specifically, the region where the orthographic projection of the blocking body 30 on the atomizing surface 11 is located may completely overlap with the second atomizing area 112, or may overlap only, and is not particularly limited.

The blocking body 30 may be a dense body, for example, quartz, glass, dense ceramic or silicon, and when the blocking body 30 is made of glass, it may be one of ordinary glass, quartz glass, borosilicate glass and photosensitive lithium aluminosilicate glass. It should be noted that when the blocking body 30 is a dense body, it is also possible to have pores, the porosity of which should be different from that of the porous matrix, in particular, the porosity of the blocking body 30 should be smaller than that of the porous matrix.

In the atomizing core 100 of the present utility model, the blocking body 30 is disposed in the second atomizing area 112, that is, in the area where the temperature is relatively low during atomization, so that the aerosol-generating substrate is blocked from flowing into the area, and the atomizing area is limited to the first atomizing area 111 where the heating element 20 is located, so that atomization in the low-temperature second atomizing area 112 can be completely avoided. In addition, since the temperature of the first atomization zone 111 where the heating element 20 is located is the highest, the explosive force is the strongest, and a high supersaturation degree can be given when atomizing the aerosol-generating substrate, equal-ratio atomization is maximally realized, so that the consistency of the feeling before and after suction is good, and the aroma of the reduced aerosol-generating substrate can be maximized.

In addition, since the aerosol-generating substrate is prevented from being atomized in the second atomization zone 112, the energy required for heating the aerosol-generating substrate by the second atomization zone 112 is saved, and the energy utilization rate of the heating element 20 during atomization is improved.

Referring again to fig. 1, in some embodiments, the other surfaces of the substrate 10 except the atomizing surface 11 are exposed outside the atomizing core 100.

In particular, in the embodiment of the present utility model, one side surface of the substrate 10 is an atomizing surface 11, and the side surface opposite to the atomizing surface 11 is a liquid suction surface 12, and besides, the substrate 10 further includes a plurality of side surfaces 13 disposed between the atomizing surface 11 and the liquid suction surface 12, and both the side surfaces and the liquid suction surface 12 are exposed to the outside of the atomizing core 100. Specifically, the substrate 10 may have a rectangular shape, a cylindrical shape, a V-shape, or the like, and is not particularly limited.

It will be appreciated that the baffle 30 of the present utility model does not extend to other surfaces of the substrate 10 than the defogging surface 11.

Thus, the stability of the structure of the heating element 20 is not affected, and the process can be simplified.

In some embodiments, the heat-generating body 20 is a porous heat-generating body, and the blocking body 30 may be a porous blocking body, and the porosity of the heat-generating body 20 is greater than the porosity of the blocking body 30.

In this way, when the aerosol-generating substrate enters the substrate 10 and flows toward the atomizing surface 11, the aerosol-generating substrate is attracted by the porous heat generating body having a larger porosity and concentrated in the first atomizing area 111, so that the aerosol-generating substrate stays in the second atomizing area 112 where the barrier 30 is located, and the supersaturation degree of the aerosol-generating substrate in the first atomizing area 111 is further improved.

Alternatively, the porosity of the blocking body 30 is less than 20%, and the porosity of the heat-generating body 20 ranges from 20% to 70%.

In this porosity range, the difficulty in manufacturing the barrier 30 and the heating element 20 can be reduced.

Specifically, the pore diameter of the porous heating element ranges from 10 mm to 50 mm.

In the embodiment of the present utility model, when the substrate 10 is a porous substrate, the porosity of the porous substrate ranges from 50% to 80%.

Specifically, the pore diameter of the porous matrix ranges from 15 mm to 60 mm.

In some embodiments, to simplify the manufacturing process of the atomizing core 100, the heat generating body 20 is integrally formed with the blocking body 30.

Specifically, the heat-generating body 20 and the blocking body 30 are integrally formed by a printing process. The material of the heating element 20 and the material of the blocking body 30 may be the same.

Of course, in other embodiments, the material of the heat generating body 20 may be different from that of the blocking body 30.

In the embodiment of the present utility model, the heating element 20 is a heating film, and the molding method may be a silk screen method, a vacuum coating method, or the like.

Specifically, when the heating film is prepared by adopting a silk screen printing mode, the heating film slurry has certain fluidity, the slurry can infiltrate into the pores of the porous matrix during printing, as the pores of the porous matrix are not through holes, certain tortuosity exists, the pore wall is not smooth, the slurry infiltration resistance exists, the porosity is low or the viscous resistance of the pore wall of the porous matrix with smaller pore diameter (15-60 microns) is larger, and the infiltration degree of the heating film slurry is lower. Meanwhile, the infiltration amount can be regulated and controlled by adjusting the high-temperature fluidity of the heating film material or the viscosity of the slurry at low temperature.

Preferably, the thickness of the heat generating film ranges from 15 micrometers to 150 micrometers, and the thickness of the portion of the heat generating film filled in the porous substrate is not more than 60% of the entire thickness of the heat generating film.

By controlling the amount of heat generating film infiltration, the superheated boiling of the aerosol-generating substrate inside the atomizing core 100 can be reduced, thereby reducing heat loss and improving atomization efficiency.

When the heating film is prepared by adopting a vacuum coating mode, the heating film can be prepared by adopting a magnetron sputtering coating process, and a small amount of infiltration is formed in the pores of the porous matrix by the heating film material. The thickness of the heating film can be controlled to be 1-5 microns.

Therefore, the quantity of the heating film penetrating down to the porous matrix is small, so that the generated heat is also small, the energy utilization rate is improved, and a small quantity of penetrating down provides physical embedding between the heating film and the porous matrix, so that the binding force of the film matrix is enhanced, and the structural reliability of the heating film can be improved.

Referring again to fig. 2-4, in some embodiments, the heat-generating body 20 includes a heat-generating element 21, a first electrode 22, and a second electrode 23, the first electrode 22 and the second electrode 23 being connected to the heat-generating element 21.

In this way, the heating element 21, the first electrode 22, and the second electrode 23 can be provided on the atomizing surface 11 at the same time, and the connection process can be simplified.

Specifically, the first electrode 22 and the second electrode 23 may be connected to opposite ends of the heating element 21.

Specifically, the heating element 21 may have a rectangular shape, but in other embodiments, may have a bent shape such as an S-shape, which is not particularly limited.

Referring to fig. 2, when the area where the orthographic projection of the blocking body 30 on the second atomizing area 112 is partially overlapped with the second atomizing area 112, in some embodiments, the second atomizing area 112 includes a first boundary 1121, the first boundary 1121 is not adjacent to the first atomizing area 111, the orthographic projection of the blocking body 30 on the second atomizing area 112 forms a projection area, and the first boundary 1121 and the projection area are spaced from each other.

In consideration of the fact that a region far from the heating body 20 forms an extremely low temperature region, which is insufficient in temperature to atomize the aerosol-generating substrate, the projection region of the blocking body 30 on the second atomizing region 112 and the first boundary 1121 are spaced apart from each other, so that the formation material of the blocking body 30 can be saved and the process can be simplified.

Referring to fig. 3 and 4, in some embodiments, the blocking body 30 is spaced apart from the heating body 20.

Specifically, the second atomizing area 112 further includes a second boundary 1122, the second boundary 1122 being adjacent to the first atomizing area 111, and the orthographic projection of the blocking body 30 on the second atomizing area 112 forms a projection area, the second boundary 1122 being spaced apart from the projection area. In an embodiment of the present utility model, the first boundary 1121 and the second boundary 1122 may be disposed opposite to each other.

Because of the uncontrollability of the manufacturing process, the blocking body 30 may have an intersection with the heating body 20 during the manufacturing process, which may cause dry heating of the heating body 20 at the intersection due to lack of aerosol-generating substrate, and thus, providing the blocking body 30 and the heating body 20 to be spaced from each other may prevent the heating body 20 from interfering with each other, so as to improve the heating atomization efficiency.

In other embodiments, the first boundary 1121 of the second atomizing area 112 and the projection area formed by the barrier 30 are spaced apart from each other, and the barrier 30 and the heat generating body 20 are spaced apart from each other.

In particular, in the embodiment of the present utility model, the blocking body 30 and the heating element 21 of the heating body 20 are spaced apart from each other. More specifically, the second boundary 1122 is adjacent to the orthographic projection of the heating element 21 formed at the first atomization zone 111.

It should be noted that, when the heating element 21 is curved, for example, S-shaped, the blocking body 30 may be provided in a curve formed by the curved heating element 21, and the blocking body 30 is provided at an interval from the heating element 21 along the circumferential direction thereof.

In this way, the structure similar to a river levee can be formed between the heating element 20 and the blocking body 30, so that the elevation of the oil film in the interval area is facilitated, and the effective amount of the heating element 20 for atomizing the aerosol-generating substrate is increased.

Based on the same inventive concept, the present utility model also provides an atomizer comprising the atomizing core 100 in any of the above embodiments.

Specifically, the atomizer further comprises a housing in which a reservoir for storing the aerosol-generating substrate is formed.

In some embodiments, the atomizer further comprises a seal that wraps around the other surfaces of the base 10 than the liquid suction surface 12 and the atomizing surface 11.

By providing a seal to cover the other surfaces of the substrate 10, except the liquid suction surface 12 and the atomizing surface 11, leakage of the aerosol-generating substrate from the substrate 10 can be reduced, and further, the saturation of the aerosol-generating substrate of the substrate 10 can be improved.

Specifically, the sealing element is a silica gel sealing element, and the sealing element may be an elastic sealing element made of other materials, which is not particularly limited.

Based on the same inventive concept, the utility model also provides an electronic atomization device, which comprises the atomizer in any embodiment.

Specifically, the electronic atomizing device further comprises a power supply assembly capable of providing electrical energy to the atomizing core 100 for the atomizing core 100 to heat the atomizing aerosol generating substrate.

The atomizing core 100, the atomizer and the electronic atomizing device provided by the embodiment of the utility model have the following beneficial effects:

by providing the blocking body 30 in the second atomizing area 112, i.e., in an area where the temperature is relatively low during atomization, the flow of the aerosol-generating substrate to this area is blocked, and restricting the atomizing area to the first atomizing area 111 where the heat generating body 20 is located, atomization in the low-temperature second atomizing area 112 can be completely avoided. In addition, since the temperature of the first atomization zone 111 where the heating element 20 is located is the highest, the explosive force is the strongest, and a high supersaturation degree can be given when atomizing the aerosol-generating substrate, equal-ratio atomization is maximally realized, so that the consistency of the feeling before and after suction is good, and the aroma of the reduced aerosol-generating substrate can be maximized.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples merely represent a few embodiments of the present utility model, which are described in more detail and are not to be construed as limiting the scope of the patent. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
