Heating assembly and vaporizer

Abstract

A heating assembly includes: a liquid guiding element; and a heating element arranged on a vaporization surface formed by the liquid guiding element, the heating element being energizable to generate heat. The heating element includes a first heating part and a second heating part. A temperature coefficient of resistance of the first heating part is greater than a temperature coefficient of resistance of the second heating part. The first heating part and the second heating part form an electrical connection structure.

What is claimed is: 
     
         1 . A heating assembly, comprising:
 a liquid guiding element; and   a heating element arranged on a vaporization surface formed by the liquid guiding element, the heating element being configured to be energized to generate heat,   wherein the heating element comprises a first heating part and a second heating part,   wherein a temperature coefficient of resistance of the first heating part is greater than a temperature coefficient of resistance of the second heating part, and   wherein the first heating part and the second heating part form an electrical connection structure.   
     
     
         2 . The heating assembly of  claim 1 , wherein a material of the first heating part comprises a first alloy, and a material of the second heating part comprises a second alloy, and
 wherein the first alloy comprises at least one of stainless steel and a silver-platinum alloy, and/or the second alloy comprises a nickel-chromium alloy.   
     
     
         3 . The heating assembly of  claim 1 , wherein a length of the first heating part ranges from 0.5 mm to 3.0 mm, and
 wherein a length direction of the first heating part corresponds to a flow direction of a current flowing through the first heating part.   
     
     
         4 . The heating assembly of  claim 1 , wherein the heating element comprises a heating center,
 wherein the first heating part is arranged at the heating center, and   wherein a maximum temperature formed by the heating element at the heating center is greater than a maximum temperature formed by the heating element at a position outside the heating center.   
     
     
         5 . The heating assembly of  claim 1 , wherein the heating element comprises an electrode connection region,
 wherein the first heating part is arranged in the electrode connection region, and   wherein an electrode electrically connected to the heating element is located in the electrode connection region.   
     
     
         6 . The heating assembly of  claim 1 , wherein the first heating part and the second heating part are arranged in contact with each other to form the electrical connection structure connected in parallel. 
     
     
         7 . The heating assembly of  claim 1 , wherein two ends of the first heating part are electrically connected to the second heating part in different segments separately to form the electrical connection structure connected in series. 
     
     
         8 . The heating assembly of  claim 1 , wherein the heating element comprises at least two first heating parts, and
 wherein the at least two first heating parts are spaced apart in an extending direction of the second heating part.   
     
     
         9 . The heating assembly of  claim 1 , wherein the heating element comprises:
 at least one first segment; and   at least one second segment,   wherein the at least one first segment and the at least one second segment are connected end to end to form the heating element, and   wherein an extending direction of the first segment is different from an extending direction of the second segment.   
     
     
         10 . A vaporizer, comprising:
 the heating assembly of  claim 1 .
