The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

An embodiment of the present invention provides an electronic smoking article that includes a power supply assembly and an atomizer 10. The power supply assembly supplies power to the electronic cigarette. Optionally, the power supply component comprises a battery. Of course, in some embodiments, the power supply components may not include a battery. At this moment, the power supply assembly is electrically connected with the external power supply so that the external power supply can supply power to the electronic cigarette.

Referring to fig. 1, the atomizer 10 includes a housing 110, a center post 130, and a heating element. The central column 130 is located in the housing 110, the central column 130 is a hollow yttria-stabilized zirconia body, an airflow channel 131 is formed at the hollow part of the central column 130, a liquid inlet 133 is formed on the central column 130, and the central column 130 and the housing 110 form a liquid storage cavity 150 for storing atomized liquid; the heating element is positioned in the central column 130, is close to the liquid inlet 133 and is used for atomizing the atomized liquid in the liquid storage cavity 150. When the atomizer 10 is in operation, the atomized liquid in the liquid storage cavity 150 flows out from the liquid storage cavity 150, enters the center post 130 through the liquid inlet 133 of the center post 130, contacts with the heating element of the center post 130, is atomized into aerosol, and flows out from the airflow channel 131 of the center post 130 for suction.

Specifically, the housing 110 is a hollow structure. In the embodiment shown in fig. 1, the housing 110 is generally a hollow cylinder. Of course, in other embodiments, the shape of the housing 110 is not limited to a hollow cylinder, but may be other shapes, such as a hollow quadrangular prism. In this embodiment, the housing 110 is a food-grade glass housing 110. The glass housing 110 facilitates viewing of the atomized liquid in the reservoir 150 formed by the housing 110 and the center post 130. In addition, the food-grade glass housing 110 also makes it less likely that the atomized liquid in the reservoir 150 will detect substances that are harmful to health. Of course, in other embodiments, the material of the housing 110 is not limited to the above, and may be other food-grade rigid materials.

Specifically, the center post 130 is substantially hollow and tubular. Referring to fig. 2 and 3 together, in the embodiment shown in fig. 3, the diameter of the portion of the center post 130 close to the heating element is larger than that of the portion far from the heating element so as to accommodate the heating element. Of course, in other embodiments, the shape of the central post 130 is not limited to a hollow circular tube shape, but may be other shapes.

The center post of traditional atomizer generally adopts brass, stainless steel or other metals, but brass and stainless steel impurity are many, and easy electrically conductive has the risk of short circuit, but also contains heavy metal such as lead, breeds the fungus class easily. Yttria-stabilized zirconia (YSZ) is a ceramic material, and the addition of Yttria changes the phase transition temperature range of zirconia to produce cubic and tetragonal crystals that are stable at room temperature. Yttria-stabilized zirconia is a white odorless and tasteless crystal under normal conditions, is difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid, is inactive in chemical properties, and is insulating and high-temperature resistant. Therefore, the central column 130 is a hollow yttria-stabilized zirconia body, so that bacteria are difficult to breed on the central column 130, and the risk of sucking harmful bacteria is greatly reduced; the central column 130 can be smooth and exquisite in appearance without glazing, good in physical ductility, and difficult to deteriorate atomized liquid in the liquid storage cavity 150 when contacting the atomized liquid in the liquid storage cavity 150, so that harmful substances are not easy to generate during atomization; in addition, the insulating property of the center post 130, which is an yttria-stabilized zirconia body, also makes the atomizer 10 less prone to short-circuiting, further improving the safety of the atomizer 10.

Further, in the center pillar 130, the mass ratio of zirconia to yttria is (86.5 to 97): (3-13.5). Further, in the central pillar 130, the mass ratio of zirconia to yttria is (93 to 97): (3-7). In one alternative specific example, the ratio of zirconia to yttria by mass is 94.8: 5.2. the mass ratio of zirconia to yttria was set to 94.8: 5.2, the molding can be more stable when preparing the yttria-stabilized zirconia body. Alternatively, in some embodiments, the center post 130 is prepared using yttria powder and zirconia powder. In some embodiments, at least one of paraffin, polypropylene, and polyethylene is also added when the center post 130 is made. The paraffin can improve the fluidity of the powder zirconia and the yttria, and is beneficial to injection molding; the polypropylene and the polyethylene can improve the strength of the embryo body after injection molding, so that the embryo body is not easy to deform. Of course, the paraffin, polypropylene and polyethylene are removed in the subsequent binder removal process.

Specifically, an elastic sealing member 160 is disposed between the housing 110 and the center post 130. The gap between the housing 110 and the center post 130 is sealed by the elastic sealing member 160, so that the atomized liquid in the liquid storage cavity 150 formed by the housing 110 and the center post 130 is prevented from leaking; while the elastomeric seal 160 also acts as a cushioning member between the rigid housing 110 and the rigid center post 130, such that the housing 110 and center post 130 are not easily deformed or broken. In an alternative specific example, the resilient seal 160 is a food grade silicone ring. In the embodiment shown in fig. 3, the number of resilient sealing members 160 is two, one resilient sealing member 160 being proximal to the air inlet 135 and the other being distal to the air inlet 135.

In the present embodiment, the fixing portion 171 is a brass ring, and the thickness of the portion where the fixing portion 171 is riveted to the center post 130 is not more than 1 mm. The thickness of the riveted part of the fixing part 171 and the central column 130 is set to be not more than 1mm, so that the fixing part 171 can be riveted with the central column 130 but not deform and break the central column 130. In an alternative specific example, the thickness of the portion where the fixing portion 171 is riveted with the central pillar 130 is 0.3mm, 0.5mm, or 0.85 mm. Of course, in other embodiments, the material of the fixing portion 171 is not limited to brass, and may be other materials. The thickness of the portion where the fixing portion 171 is riveted to the center post 130 can be adjusted according to the specific material.

The connection part 172 is a portion where the fixing member 170 is connected to the battery pack. In the embodiment shown in fig. 3, the connection portion 172 has threads thereon to facilitate mounting of the battery pack. It is understood that the fixing member 170 is not limited to the screw connection, but may be fixed to the battery pack by other fixing means, such as snap connection. Of course, in some embodiments, the connecting portion 172 is made of a conductive material, and in this case, the connecting portion 172 serves as both a component for connecting the battery assembly and the center post 130 and a conductive component for supplying power to the heating element in the center post 130.
