A cigarette lighter with an easy-to-replace electric heating unit

Abstract

The invention discloses a cigarette lighter with an electric heating unit easy to replace. The cigarette lighter comprise a shell and a cover, and a middle frame, a circuit board, a battery, a switch, the electric heating unit and an electric heating unit cover are installed in the shell and the cover; a socket for allowing the electric heating unit to insert is formed in the middle frame; the electric heating unit comprises an electric heating part, an electric heating circuit board electrically connected with the electric heating part, an insulating sheet and a housing, the electric heating part, the electric heating circuit board and the insulating sheet are sequentially installed in the housing in a sandwich structure to form an integral structure, a through hole for allowing local of the electric heating part to be exposed is formed in the housing, and the electric heating circuit board is inserted into the socket through the extension end exposed out of the housing and matched with an insertion groove formed in the circuit board through a contact pin to form close insertion fitting; the electric heating unit cover is provided with an installation cavity for allowing the electric heating unit to slide in and a cigarette lighting opening corresponding to the electric heating part, and the electric heating unit cover is attracted to the middle frame through magnetic sheets. The cigarette lighter has the advantages of being stable in electrical contact, firm in installation structure, easy, convenient and rapid to disassemble and replace and the like.

Description

technical field [0001] The invention belongs to the technical field of cigarette lighters, in particular to a cigarette lighter with an easily replaceable electric heating unit. Background technique [0002] At present, cigarette lighters or lighters on the market can be divided into open flame cigarette lighters, windproof fire cigarette lighters and electric heating cigarette lighters according to their different ignition methods; Cigarette lighters are relatively common, but with the popularity of electronic products, electric heating cigarette lighters are becoming more and more popular among consumers. However, because the electric heating cigarette lighter in the prior art works by igniting the shredded tobacco of the cigarette through its internal electric heating unit, in the process of lighting cigarettes, due to the contact between the shredded tobacco and the electric heating wire, use After a period of time, it is easy to cause oxidation of the electric heating ...

AI Technical Summary

Problems solved by technology

In the cigarette lighter in the above structure, the electric heating wire ignition head is inserted into the electric heating wire ignition head frame, and then the pins of the electric heating wire ignition head frame and the socket on the middle frame play a fixed role by buckling the card slot and the boss structure, although the The structure is as mentioned in the article, and it can be disassembled without tools. However, since the boss structure is located inside the socket of the middle frame, its structure is not easy to see. When assembling or disassembling, because the buckle structure is located inside the middle frame, it is not easy Observation shows that it is difficult to work without effort, and the cooperation between the card slot and the boss structure is easy to appear cracks on the side wall where the card slot is located due to repeated extrusion, resulting in gaps in the card slot. Such accidents will affect the service life of the electric heating wire ignition head frame, and once the structure of the electric heating wire ignition head frame is damaged, the electric heating wire ignition head cannot be stably installed on the middle frame; moreover, the above-mentioned electric heating wire ignition head parts Scattered, and after it is inserted into the ignition head frame of the heating wire, it is necessary to form an effective point contact between the plug-in part of the ignition wire of the heating wire and the positive and negative conductive sheets on the circuit board. Technical requirements, if there is a deviation in assembly, it is easy to cause unstable contact between the ignition head of the heating wire and the circuit board; moreover, due to the formation of an If the plane is in contact with the raised point, the matching structure itself needs to be fixed by foreign objects to form a stable contact, otherwise it is prone to poor contact; in addition, the cigarette lighter with the above structure has scattered structural components and cumbersome assembly steps. The assembly operation has certain technical requirements. For ordinary consumers, it is difficult to install and disassemble by themselves.
