Abstract

The utility model relates to a direct-charging electric torch which comprises an electric torch head composed of a screw bulb, a screw lamp cap and a condenser lens, a switch, an electric torch body, a plug and a display. One or a plurality of monomer storage batteries are arranged in the electric torch body. The storage battery is provided with a partition board which is cast and bonded with the electric torch body and the connection has no gaps, only allowing migration of ions. Both sides of the partition board are provided with electrodes. A cover plate which seals the storage battery is provided with an exhaust device which can be used for draining air and injecting electrolyte, ensuring that no matter which place the electric torch is placed, electrolyte can not leak. A pasted electrode can be used. The utility model has the advantages of simple structure, easy fabrication, and long service life and charging can be carried out for more than 1500 times.

Description

Direct chargeable flashlight

The utility model relates to the direct chargeable flashlight that is used to throw light on.

All adopt the flashlight of battery all not solve electrolyte leakage and problem of short-circuit in the use up to now.Therefore, use both dangerously, the life-span is short again.

Chinese patent No.87207912 discloses a kind of rechargeable type flashlight, and the battery of this flashlight is by inhaling by separation layer, the wettable layer of the sorptive material of suitable electrolyte, doing wet absorption chamber etc. and form.Though solved the leakage problem of electrolyte,, thereby made active material lose storage function because that electrolyte volatilization is dried up is dried; Sorptive material is easily breakdown when overcharging, thereby forms short circuit, causes torch to scrap.This torch complex structure is made difficulty.Chinese patent No.89212296 discloses and a kind ofly chargeablely many use emergency light, and this lamp can not be inverted, and is inverted to have the electrolyte outflow, and is both dangerous, lost the battery function again.

The purpose of this utility model is to avoid above-mentioned shortcoming of the prior art, and a kind of direct chargeable flashlight is provided, and this flashlight is safe and reliable, and no electrolyte flows out; Can not form short circuit, battery life is long; Simple in structure, easily manufactured.

The purpose of this utility model reaches by following approach.The direct chargeable flashlight that is used to throw light on, comprise torch head, two-way switch, torch body, plug and display that screw-socket bulb, screw socket, condenser are formed, in the torch body, adorn one or more cell batteries near the first end of torch, this battery have one with torch body casting or bonding all-in-one-piece dividing plate, pole plate is installed in the dividing plate both sides, on the cover plate of closed secondary battery, exhaust apparatus is installed, charger is installed at tail end near cover plate.

Dividing plate and torch body casting are one or with fluid sealant dividing plate and torch body are bonded together that four limits are all seamless, guarantee that the both positive and negative polarity active material can not gang up mutually, therefore can short circuit.Both positive and negative polarity can use the starchiness electrode, overcharges repeatedly can not damage battery; Exhaust apparatus both can be discharged the gas that produces in the chemical reaction, can inject electrolyte again, and can guarantee that torch where position in office is placed and the electrolyte leakage phenomenon can not take place.Charger adopts high isolation technology microminiature charging module, has constant voltage and current limiting, overheated overcurrent protection function, and the overload charging ability is strong, long service life.

When torch body and dividing plate are adopted bonding way with anticorrosive gluing connecing.

The pole plate of battery can be made pasty electrode.

The pole plate of battery also can be made the paste spread type electrode.

The anti-corrosion pipe that exhaust apparatus is 0.3mm-10mm by corrosion resistant gettering material and at least one diameter is formed.

Charger adopts the microminiature charging module of high isolation technology.

Charger also can be a transformer type step-down rectifier charger.

Adopt the alternating current 220V power supply during the utility model charging.

Provide accompanying drawing of the present utility model below.

Fig. 1 is the profilograph of direct chargeable flashlight.

Embodiment is described in detail the utility model below in conjunction with accompanying drawing.Dividing plate (4) is two pole plates (12) separately, because dividing plate (4) bonds together with cylindrical shell (5) casting or with anticorrosive fluid sealant, therefore any slit can not arranged in torch, only allow the ion migration in the electrolyte, can not form active material moves mutually in the dividing plate both sides, all the time the battery short circuit phenomenon be can not form, cycle-index and anti-over-charging electric energy power that battery charges repeatedly improved.Charging times can reach more than 1500 times.Exhaust apparatus (10) is made up of corrosion-resistant gettering material and pipe, can absorb and discharges the gas that produces in the chemical reaction; Also can inject electrolyte thus, normally carry out to guarantee chemical reaction and electrochemical reaction; In any case can also guarantee that the torch placement does not have electrolyte and flows out.When switch connection, cation will be constantly to the cathode flow of torch, thereby form electric current, bulb is bright.

This flashlight can directly be released the back with the plug of hiding by pull bar and insert on the 220v AC power, and with the battery abundance, display shows full condition by microminiature modular charger.Being full of load once can use more than 1 week.
