The purpose of this utility model provides a kind of multifunctional portable electronic flow fee register.One, is easy to carry.Two, can carry out flow, price conversion, accumulative total and demonstration to multiple liquid.Three, can automatically prevent fires, put out a fire.Four, can carry out liquid level warning.Five, can carry out the conversion of weight and price to multiple liquid.

The utility model be achieved in that it comprise liquid main pipe (hereinafter to be referred as main pipe), be contained in the panel of the outer fluid inlet end of main pipe, at the fire extinguishing agent box of main pipe periphery be contained in four parts such as inner bag bracing frame of liquid outlet end in the main pipe.Flow, price conversion, accumulative total and display device are housed, full-automatic firebreak device, full-automatic fire-extinguishing device, liquid level alarm device and class of liquids selecting arrangement in these four parts.

Flow wherein, price convert, accumulative total and display device by be contained in impeller in the inner bag bracing frame, be contained in liquid main pipe outer wall magnetoresistive transducer, be contained in the circuit board in the panel, display and the supervisory keyboard on panel formed.

Impeller design is a spirality, studs with permanent magnet on the blade of impeller.

Function key on the supervisory keyboard: ON is that switch connection shows; OFF is that switch disconnects, stops to show; M is for showing instant flow, instant price, integrated flow, accumulative total price; N for show instantaneous weight, instant price, general assembly (TW), total price (according to zone bit+,-).Certainly, also can replace M, N with other character.Numeral 0～9 and ". " (radix point) are as the unit price data entry key.Symbol "-" is used as " taking advantage of " or " equaling ".Also has the class of liquids selector switch on the supervisory keyboard.

Full-automatic firebreak device is by being contained in temperature sensor, circuit board in the panel, comprising that in the inner bag bracing frame fire prevention electromagnetic valve of baffle plate and fire prevention solenoid valve is formed.

The full-automatic fire-extinguishing device is made up of the above-mentioned temperature sensor in panel, above-mentioned fire extinguishing agent box, fire extinguishing solenoid valve and the fire extinguishing agent in box.

The liquid that liquid level alarm device prevention adds surpasses needed liquid level and is provided with, it by be embedded in liquid level sensor on the liquid main pipe outer wall, in the inner bag bracing frame the fire prevention electromagnetic valve, in panel circuit board and formed at the hummer of panel inboard.

The class of liquids selecting arrangement is provided with in order to measure different types of liquid (for example: gasoline, diesel oil, kerosene, alcohol), because different liquid has different proportion usually.This device is made up of class of liquids selector switch and circuit board on panel.

When the fuel tank transfusion of tilting reservoir port is arranged, be preferably in one section universal conduit of liquid outlet end adjunction of liquid main pipe, to guarantee normal measurement.

The integrated circuit of all electronic circuit parts of the utility model is general-purpose chip entirely, and electronic circuitry design is prior art entirely, the Therefore, omited electrical schematic diagram.Simultaneously, circuit board is fixed in the panel, for waterproof, shockproof, solidifies after the filling of employing epoxy resin.

This device adopts a slice button cell and No. 5 dry cell power supplies.

The advantage of this device is as follows: one, compact conformation, miniaturization, light and handy, be easy to carry.Two, can show instant flow and price, integrated flow and price.Three, weight and the price that can carry out multiple liquid converts.Four, can automatically prevent fires, put out a fire.Five, can carry out liquid level warning.

Further specify the structure of this fee register below in conjunction with the accompanying drawing example illustrated.

Fig. 5 is a circuit diagram of the present utility model

In Fig. 1-4, when the impeller 5 of liquid from the inlet 17 input promotion inner bag bracing frames 4 of liquid main pipe 1 rotates, permanent magnet on the blade just produces a variation magnetic field synchronous with wheel rotation, magnetoresistive transducer 6 is under the effect in this magnetic field, produce a voltage variety, this is the required pulse signal of meter fluid, and the counting circuit of the circuit board 7 in the panel 2 is whenever write down certain pulse number, just add up 1 liter flow of display 8.When supervisory keyboard 9 is selected corresponding function, LCD is controlled by the microprocessor on the circuit board on the panel, can show the instantaneous weight of instant flow, instant price, integrated flow, accumulative total price, certain liquid, instant price, general assembly (TW) and total price.The selector switch 16 that A, B, C, four kinds of liquid of D are arranged in this example.

When temperature is raised to 70 ℃, the signal of temperature sensor 10 is passed to the circuit of circuit board, produce a control signal, the electromagnetic valve that is installed on the inner bag bracing frame (is made up of baffle plate 11 and fire prevention solenoid valve 12, baffle plate is contained in the inner bag bracing frame by torsion spring and transverse axis) action, stop liquid communication, finish fire-proof function.When environment temperature continuation rising, when reaching more than 65 ℃, this temperature sensor makes circuit produce a control signal, make near 13 actions of the fire extinguishing solenoid valve in the fire extinguishing agent box 3 of panel, fire extinguishing agent 14 contacts of bi-component are mixed, and the fire foam of generation is sprayed by nozzle, finishes fire-extinguishing function concurrently.Fireproof agent box in this example is a ring bodies, is sleeved on liquid main pipe periphery.

When liquid level sensor 15 contacts with liquid, produce a control signal through oversampling circuit and make the action of fire prevention by-pass valve control, stop liquid to flow into, make the container of holding liquid such as fuel tank can not surpass required liquid level.Simultaneously, the hummer on the circuit board sends to report to the police and rings.

The liquid main pipe can be integral by being threaded of its afterbody with the inner bag bracing frame.Two mechanical positioning grooves are arranged on the liquid main pipe inwall, match with two steel balls on the inner bag bracing frame and contact, simultaneously as the control signal contact of fire prevention electromagnetic valve coil.The outlet of liquid is 18.
