Heating device for heating electronic cigarettes and electronic smoking system

Abstract

The invention discloses a heating device for heating electronic cigarettes and an electronic smoking system. The heating device for heating electronic cigarettes comprises a heating element and a fixing device for fixing the heating element, wherein the heating element comprises a substrate layer made of a metal material, a first insulating medium layer, a heating resistor layer and a second insulating medium layer are sequentially arranged on the substrate layer, and the resistance value of the heating resistor layer has temperature-related characteristics; the heating element comprises a heating part and a holding part; and the fixing device is used for fixing the heating element, the fixing device comprises a first fixing element and a second fixing element positioned below the first fixing element, and the first fixing element and the second fixing element are respectively provided with an upper fixing position and a lower fixing position on the holding part of the heating element.Compared with a traditional ceramic heating sheet, the heating element with the structure has the advantages of high mechanical strength and long service life; and in addition, the stability of the heating element can be further enhanced by the fixing device, and the heating element is not easy to bend and deform.

Description

technical field [0001] The present invention relates to the technical field of electronic smoking, in particular to a heating device for heating electronic cigarettes and an electronic smoking system. Background technique [0002] The history of smoking cigarettes has a long history. Archaeological discoveries show that when humans were still in primitive society, tobacco entered the lives of American residents. Although it has always been said that smoking is harmful to health, there is no direct evidence to prove that smoking is related to human health. There must be a direct impact, and there is no legislation to restrict people's smoking, so this not-so-good habit of human beings has been continued. From the early dry cigarettes to the current cigarettes, in order to facilitate and reflect the unrestrainedness of smokers, there have been many types and functions of smoking utensils, such as pipes, pipes, and bongs. Some people are accustomed to using special equipment t...

Problems solved by technology

[0004] At present, most of the heating parts used in electronic cigarettes are directly etched heating resistance wires on the ceramic substrate, mainly to take advantage of the good insulation and thermal conductivity of ceramics. However, due to the poor toughness of ceramic substrates, when plugging and unplugging electronic cigarettes When it is easy to be broken, the service life is short
