DETAILED DESCRIPTION OF THE EMBODIMENTS

(6) Referring to FIGS. 1-5, the first embodiment of the present invention provides a heating element 10 including a ceramic main body 100 and a heating wire 200. The ceramic main body 100 includes an upper portion 110 and a lower portion 130, wherein the upper portion and the lower portion are integrally formed. A plurality of micro-pores for oil penetration (not shown in the drawings) are distributed on the upper portion 110 and the lower portion 130. Preferably, the micro-pores are evenly distributed. A shape of a periphery of the upper portion 110 is matched with a shape of an interior of an atomizer 400 for mounting the upper portion. A side of the upper portion 110 is provided with a notch 112, and a shape of the notch 112 is matched with a shape of an air flowing tube 402 of the atomizer. Further, the shape of the notch 112 may be matched with a shape of a mounting member 404 of the air flowing tube 402 of the atomizer. The lower portion 130 extends downward from a side of the upper portion 110 opposite to the notch 112. The heating wire 200 is mounted on the ceramic main body 100, and the heating wire 200 extends outward from a bottom of the lower portion 130. The heating wire 200 is printed or inlaid and fixed to the bottom of the lower portion 130.

(7) The upper surface of the upper portion 110 is provided with an oil inlet groove 114 recessed inward. The side surface of the lower portion 130 on a same side of the notch is provided with an air outlet 132, and a position of the air outlet 132 is close to an installation position of a lower end of the air flowing tube 402 of the atomizer. In the present embodiment, the air outlet 132 is a through hole running through the heating element 10. Two uniformed turns of heating wires 200 are wound in the air outlet 132 and are connected to the heating wire 200 extending out from the lower portion 130. Winding the heating wire 200 in the air outlet 132 can improve the atomization efficiency, thereby improving the use experience. In the present embodiment, two air outlets are configured. The heating element 10 further includes a silicone sleeve 300 covering an outer surface of the lower portion 130. The silicone sleeve 300 is provided with a through hole 302 at a position corresponding to the air outlet 132.

(8) The side wall of the periphery of the upper portion 110 is configured with at least one turn of groove 116 recessed inward for placing a sealing ring (not shown in the drawings). In the present embodiment, an overall shape of the upper portion is a crescent-shaped column, and a notch of the crescent-shaped column is the notch 112 for the air flowing tube 402 of the atomizer.

(9) The heating element 10 provided by the present invention is mounted to the atomizer 400. Specifically, the heating element 10 is mounted below an oil storage chamber 406, directly connected to the oil storage chamber 406, and embedded in the mounting member 404. The mounting member 404 is further provided with a through hole 405 that allows the air flowing tube 402 of the atomizer to pass through. A base 408 is connected to the lower end of the oil storage chamber 406. A cavity is provided in the base 408 to accommodate the mounting member 404, the heating element 10, the silicone sleeve 300, and a separating piece 410. A pogo pin 412 is mounted on the lower end of the base 408, and the end of the heating wire 200 of the heating element 10 passes through the silicone sleeve 300 and is connected to the pogo pin 412 for energization and heating.

(10) In practical use, the oil is injected into the oil storage chamber 406, and uniformly permeates into the micro-pores of the heating element 10. The heating wire 200 of the heating element 10 is electrified to make the oil in the heating element 10 generate vapor. After the vapor is generated, the vapor emerges from the air outlet 132 in the heating element 10 and passes through the through hole 302 of the silicone sleeve 300 to enter the base 408. The outside air enters from the air inlet 143 of the base 408. When the suction nozzle portion 414 inhales, the outside air enters the air flowing tube 402 together with the vapor generated by the heating element 10, and passes through the air flowing tube 402 and exports from the suction nozzle portion 414.

(11) In other embodiments, any one or more technical features from the oil inlet groove 114, the air outlet 132, and the groove 116 may be removed to provide a suboptimal solution compared with a relatively optimal solution, such a technical solution should also be considered as falling within the scope of the present patent application.

(12) However, the above descriptions cannot be understood as a limitation to the scope of the present patent application. It should be noted that, various modifications and improvements can be derived by people of ordinary skill in the art without departing from the concept of the present invention. For example, different features in various embodiments may be combined. These modifications and improvements should also be considered as falling within the scope of the present invention.
