Description

Technical Field

[0001] The utility model relates to the field of electronic cigarettes, in particular to an electronic cigarette ceramic heater and an electronic cigarette. Background Art

[0002] In the prior art, a ceramic heater is provided at the bottom of the electronic cigarette oil storage chamber to heat the oil and atomize it. A conventional ceramic heater in the prior art has a groove formed on the side facing the oil, and the oil contacts the groove and the microporous ceramic surface on the outer side of the groove top. In this way, after the heating part provided at the bottom of the microporous ceramic is energized to generate heat, the heat is transferred to the surface of the microporous ceramic in contact with the oil, thereby heating the oil and finally generating a certain amount of atomization.

[0003] During the use of electronic cigarettes, every time the user smokes, a certain amount of air bubbles will enter the oil storage chamber to balance the pressure of the generated atomized gas and the atomized gas sucked out. These air bubbles tend to accumulate or gather in the above-mentioned grooves. Since some types of e-liquid are relatively thick, the bubbles in the grooves are gathered therein, so that the areas with bubbles in the grooves cannot contact the e-liquid, and the heat of the corresponding areas cannot be taken away by the e-liquid, resulting in the temperature of the microporous bubbles being higher than the set temperature. In this way, the actual heating temperature of the e-liquid is too high, so a heavier burnt or charred smell will be produced when atomized. Utility Model Content

[0004] The utility model provides an electronic cigarette ceramic heater and an electronic cigarette to solve at least one of the above technical problems.

[0005] To solve the above problems, as one aspect of the utility model, an electronic cigarette ceramic heater is provided, comprising: a microporous ceramic, a heating element and a conductive lead, the microporous ceramic comprising a first surface in contact with the electronic cigarette oil and a second surface away from the first surface, the heating element is connected to the second surface of the microporous ceramic, the conductive lead is connected to the end of the heating element, the first surface is protrudingly formed with a protrusion, and the circumference of the protrusion is a cone.

[0006] Preferably, a recessed portion is formed on the second surface of the microporous ceramic, and the heating element is disposed in the recessed portion.

[0007] Preferably, the recessed portion is conical.

[0008] Preferably, the top of the protrusion is a plane.

[0009] The utility model also provides an electronic cigarette, comprising the electronic cigarette ceramic heater.

[0010] In the above technical solution, the utility model uses the protrusions on the microporous ceramic to prevent air bubbles from being easily accumulated or gathered on the first surface of the microporous ceramic, so that the smoke oil can be more completely in contact with the first surface, avoiding the microporous ceramic from being overheated, thereby preventing the smoke oil from being overheated, and greatly improving the phenomenon of burnt or charred smell during atomization.

[0015] The following is a detailed description of the embodiments of the present invention, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0016] As one aspect of the utility model, an electronic cigarette ceramic heater is provided, comprising: a microporous ceramic 1, a heating element 2 and a conductive lead 3, wherein the microporous ceramic 1 comprises a first surface in contact with the electronic cigarette oil and a second surface away from the first surface, the heating element 2 is connected to the second surface of the microporous ceramic 1, the conductive lead 3 is connected to the end of the heating element 2, and a protrusion 4 is protrudingly formed on the first surface, and the circumference of the protrusion 4 is a conical surface. Preferably, the top of the protrusion 4 is a plane 6. The protrusion 4 is preferably in the shape of a truncated cone, for example, a truncated cone.

[0017] Preferably, a recessed portion 5 is formed on the second surface of the microporous ceramic 1, and the heating element 2 is disposed in the recessed portion 5. Preferably, the recessed portion 5 is conical. Preferably, the conical shape of the recessed portion 5 is a frustum, such as a truncated cone.

[0018] The utility model also provides an electronic cigarette, comprising the electronic cigarette ceramic heater.

[0019] When in use, the electronic cigarette ceramic heater of the utility model is installed at the bottom of the oil storage chamber of the electronic cigarette. When the oil storage chamber is filled with oil, the oil will contact the first surface of the electronic cigarette ceramic heater. Among them, the first surface faces the oil, and the protrusion 4 on its surface protrudes into the oil. The middle part of the protrusion 4 is higher and the surrounding edges are lower, forming a structure with a protruding middle and low-lying edges. In this way, during the heating of the oil, the air bubbles entering the oil storage chamber when smoking are not easy to accumulate or gather on the surface of the microporous ceramic 1, so that the oil can be more fully contacted with the first surface. Therefore, after the heating element 2 is heated by the current from the conductive lead 3, the heat generated makes the microporous ceramic 1 heat up, and the entire first surface of the microporous ceramic 1 can better contact with the oil, so that the heat of the entire surface is taken away by the oil through contact and heating of the oil, so that the oil is first atomized to a certain extent for the user to use.

[0020] Therefore, there is no local area on the first surface where the heat cannot be taken away by the e-liquid due to the existence of bubbles, so that the temperature of the entire first surface can better match the preset temperature, and the temperature of the first surface will not be too high. Therefore, the e-liquid will not be overheated, thereby avoiding the phenomenon of burnt or charred smell.

[0021] In the above technical scheme, the utility model uses the protrusion 4 on the microporous ceramic 1 to prevent air bubbles from being easily accumulated or gathered on the first surface of the microporous ceramic 1, so that the tobacco oil can be more completely in contact with the first surface, avoiding the microporous ceramic 1 from being overheated, thereby preventing the tobacco oil from being overheated, and greatly improving the phenomenon of burnt or charred smell during atomization.

[0022] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
