Abstract
The invention relates to a charging button-type battery with an explosion-proof device, which consists of a battery body and a cap, wherein the cap consists of a cap chassis, an explosion-proof ball and a nickel-plated steel cap, the cap chassis is provided with an explosion-proof safety valve air outlet hole, the explosion-proof ball and the nickel-plating steel cap are arranged on the explosion-proof safety valve air outlet hole, and the explosion-proof ball is arranged inside the nickel-plating steel cap. By adopting the nickel-plating steel cap to compress the explosion-proof ball towards the explosion-proof safety valve air outlet hole, when the pressure is more than the explosion-proof opening pressure of a battery explosion-proof valve, the pressure pushes the explosion-proof ball in the cap, so the cap is opened to discharge the air, and when the pressure is decreased to be lower than the critical value, the cap is re-closed through the elasticity of the explosion-proof ball, so the battery is free from explosion because of the large pressure. Therefore, the injure of the battery on the charging device and the personnel, caused by the explosion during the manufacturing and application process, can be prevented, and the safety of the charging button-type battery can be improved.
Description
Technical field
The present invention relates to a kind of charging button-type battery, especially a kind of charging button-type battery with explosion-protection equipment.
Background technology
Button cell, also be button cell, be meant that overall dimension resembles the battery of a little button, in general diameter is bigger, thinner thickness (with respect to No. 5 batteries such as AA on prismatic battery such as the market), button cell is to come battery is divided from profile, equal corresponding cell classification has prismatic battery, rectangular cell, special-shaped battery.Button cell is less because of the bodily form, and diameter is from 4.8mm to 30mm, and thickness does not wait from 1.0mm to 7.7mm; The back-up source that generally is used for each electronic product, as computer main board, electronic watch, electronic dictionary, electronic scale, memory card, remote controller, electronic toy etc.
Button cell is in general common charging arranged and two kinds of not charging, charging comprise 3.6V chargeable lithium ion button cell (LIR series), 3V chargeable lithium ion button cell (ML or VL series); That does not charge comprises 3V li-Mn button cell (CR series) and 1.5V alkaline zinc margunese button cell (LR and SR series).
Because charging button-type battery can produce interior pressure in charge and discharge process or during improper use.At present, both at home and abroad charging button-type battery is not with explosion relief valve, when interior pressure greater than button cell seal pressure the time, be generally 40 kilograms, can produce blast.
Summary of the invention
Purpose of the present invention just provides a kind of charging button-type battery with explosion-protection equipment.
Technical scheme of the present invention realizes by following approach, it is made up of cell body and block, wherein block a shot and form by block chassis, explosion-proof ball and nickel-plated steel cap, wherein, block has an explosion relief valve venthole on the chassis, be pressed with explosion-proof ball and nickel-plated steel cap on the explosion relief valve venthole, explosion-proof ball is located at the inside of nickel-plated steel cap.
The present invention is owing to adopt the nickel-plated steel cap that explosion-proof ball is pressed to the explosion relief valve venthole, when pressure during greater than the explosion-proof opening pressure of battery anti-explosion valve, explosion-proof ball jack-up during pressure will be blocked a shot, open venting, when pressure drops to the subcritical value, again return by the elasticity of explosion-proof ball and to close sealing, thereby battery is exploded owing to pressure is excessive.So just prevented battery manufacture and use in blast charging device and personnel damaged, increased the fail safe of charging button-type battery.
Description of drawings
Accompanying drawing is a structural representation of the present invention
Wherein: 1-block chassis, 2-explosion relief valve venthole, 3-explosion-proof ball, 4-nickel-plated steel cap, 5-cell body
Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
The present invention is made up of cell body 5 and block, wherein block a shot and form by block chassis 1, explosion-proof ball 3 and nickel-plated steel cap 4, wherein, block has an explosion relief valve venthole 2 on the chassis 1, be pressed with explosion-proof ball 3 and nickel-plated steel cap 4 on the explosion relief valve venthole 2, explosion-proof ball 3 is located at the inside of nickel-plated steel cap 4.
Explosion-proof ball 3 adopts rubber bodies or spring leaf among the present invention, and other elastomeric material.Cell body comprises battery case, sealing ring, and the spring arculae, positive/negative plate, electrolyte and barrier film are formed.
When pressure during greater than the explosion-proof opening pressure of battery anti-explosion valve, the explosion-proof ball jack-up during pressure will be blocked a shot is opened venting, when pressure drops to the subcritical value, returns again by the elasticity of explosion-proof ball and to close sealing, thereby battery is exploded owing to pressure is excessive.
