Abstract

A safety electric ignition device includes an electronic indenter, a synchronous bar, an auxiliary spring, a position protection card, an electronic movable rod, an electronic main body cover, a compression spring, an electronic hitter, a back-moving spring, a piezoelectric ceramic, an electronic metal hat, and a high voltage wire. The auxiliary spring is installed on the synchronous bar between the electronic indenter and the position protection card. Thereby when the safety electric ignition device is pressed, the compression spring and an auxiliary spring generate compressive resistance meeting 8.5 pounds assurance force coefficient defined in EU CR regulations concurrently, which drives an electronic hitter to press the piezoelectric ceramic to generate heavy pressure for ignition . When the electronic indenter is in the reflex status, the auxiliary spring assists the compression spring to generate restoring force concurrently, thereby overcoming insufficient restore force. The utility model has simple structure, security and long durability.

Description

The safe electronic igniter

Technical field

The utility model relates to a kind of safe electronic igniter.

Background technology

The electronic ignition device of present domestic use generally comprises plain edition and scale-up version, their structure all mainly comprises electronic behavior bar, compression spring, electronic beating head, electronic metal cap and this several sections of piezoelectric ceramics, these traditional electronic ignition devices have following defective: 1. the compressive resistance of the compression spring of plain edition electronic ignition device is little, can not satisfy the safety requirements of 8.5 pounds of performances of compressive resistance of the CR of European Union rules and regulations; 2. though the scale-up version electronic ignition device has adopted the practice of overstriking compression spring to make compressive resistance reach safety coefficient, but, this electronic ignition device is after often using, to cross by force and make piezoelectric ceramics early decrease qualitative change owing to the electronic beating head impulsive force, thereby cause occurring short defective in service life; 3. no matter be " common " type or the electronic ignition device of " increasing the weight of " type, ubiquity returning place force defect of insufficient.

The utility model content

The purpose of this utility model is to overcome the defective of prior art, a kind of safe electronic igniter is provided, this safe electronic igniter has solved the defective of the returning place force difference of back-moving spring in the prior art effectively, and alleviated impact spring and the electronic beating head impulsive force (destructive power) to piezoelectric ceramics, it has the advantage of the strong and long service life of simple in structure, security performance.

Safe electronic igniter of the present utility model comprises: electronics pressure head, synchronizing bar, secondary spring, protect position a card, electronic behavior bar, electronics main body cover, compression spring, electronic beating head, back-moving spring, piezoelectric ceramics, electronic metal cap and high-voltage conducting wires.Described electronics pressure head, synchronizing bar and the electronic behavior bar structure that is connected as one, in addition, electronics main body cover and protect the position card structure that is connected as one, a described jig that protects has the hole that can penetrate synchronizing bar, the lower end of synchronizing bar is to penetrate to protect the intrapore of position card, described secondary spring is enclosed within on the synchronizing bar, is in the electronics pressure head and protects between the position card.Like this, when pressing down the electronics pressure head of this safe electronic igniter, compression spring and secondary spring will produce the compressive resistance of 8.5 pounds of safe force coefficients that effectively satisfy the CR of European Union rules defined jointly, make electronic beating head percussive pressure electroceramics produce high pressure and light a fire.When this safe electronic igniter was in recoil state, secondary spring produced restoring force jointly with the assisting pressure spring, thereby replenished back-moving spring returning place force defect of insufficient effectively.

Safe electronic igniter of the present utility model adopts the design of spring-assisted reduction, at first, has overcome the defective of ordinary electronic igniter poor safety performance, guarantees to satisfy the security performance requirement of the CR of European Union rules defined effectively; The second, overcome that scale-up version electronic ignition device in the prior art adopts the practice of overstriking compression spring and the igniter short defective in service life that causes; The 3rd, solved the problem that the common back-moving spring that exists of plain edition electronic ignition device and scale-up version electronic ignition device returns the power difference, therefore, have simple in structure, security performance strong and the advantage of long service life.
