Description

A kind of portable electronic Fuel-filling metering table

Technical field: the utility model belongs to employing microelectric technique and modern measurement technology is used for the field of measuring techniques that oiling is measured and detected to motor vehicle.

Background technology: automobile needs to refuel, but traditional Fuel-filling metering all is only to rely on the measuring apparatus of refuelling station to reflect and calculate, the consumer can not measure and detect volume read-out by other means, causes the consumer to be subjected to the deception of some non-honest refuelling station businessmans.

Summary of the invention: the utility model provides a kind of portable electronic Fuel-filling metering table that can in time advance metering and detect oil inlet quantity just when refueling for the deficiency that solves above-mentioned existence.

The utility model is achieved by the following technical solution:

In a housing that includes inlet end and endpiece in a tubular form, be provided with a turbine and preceding turboshaft support and back turboshaft support; Before the turboshaft of turbine inserts respectively in the back central axis hole of the preceding central axis hole of turboshaft support and back turboshaft support, before on preceding turboshaft support and back turboshaft support, being sealedly connected with respectively flow guiding head and after flow guiding head; Between preceding flow guiding head and back flow guiding head and inner walls, form an annular fluid passage, in the sealed cavity body of preceding flow guiding head, be placed with battery; Be provided with a single-chip microcomputer metering display in the outside of tubular shell, side at the single-chip microcomputer metering display is provided with a power switch, be furnished with 2～10 discontinuous magnet steel at the middle part of turbo blade, and be provided with a magnetic signal receiving trap based on the Hall element principle in the inside of preceding turboshaft support; This single-chip microcomputer metering display is connected with the magnetic signal receiving trap by the hole of drawing that lead is passed on the tubular shell to be opened; Be provided with the rubber ring of an anti-leakage of oil that cooperates with nozzle at the entrance point of housing, the socket of this rubber ring is an introvert; Endpiece at housing is provided with a bearing that cooperates with fuel tank cap; The middle shaft head that the utility model is provided with in the middle of turbo blade is pointed; The nose shape of preceding flow guiding head and back flow guiding head is bullet-shaped.

When fluid flows through the entrance point of housing, rotate because of the axial line that the acting force that is subjected to fluid centers on housing at the blade of turbine and the inclination angle that axial line is of housing, to be this fluid be decomposed into two power to the acting force of turbo blade by the inclination angle to its principle, one of them power is owing to produce the power of a promotion turbine around the turboshaft rotation perpendicular to direction blade, under the effect of this power, turbine can be rotated with the axial line of turboshaft around housing, when fluid flow fast the time, turbine rotates soon, when fluid flow slow the time, turbine rotates slowlyer, in view of the above, can calculate the volume amount that fluid flows through according to the velograph of turbine rotation; Owing to be provided with 2～10 discontinuous magnet steel at the middle part of turbo blade, when turbine rotates, can drive this magnet steel rotates together, because the preceding turboshaft support of turbine distance is very near, just the magnetic induction of magnet steel is passed to the magnetic signal receiving trap of turboshaft internal stent before being arranged on, received magnetic signal is converted to electric signal and passes the SCM Based signal processor that is connected to outside by the aperture in the middle part of the cross hang plate of one group of lead the past turboshaft support by the magnetic signal receiving trap; Signal processor is handled this Magnetic Induction signal, and is converted to electronic pulse signal, and signal processor is converted to corresponding flow volume signal with this pulse signal; And by providing drive current to make liquid crystal indicator measure demonstration accordingly to a liquid crystal indicator; Between preceding turboshaft support and the preceding flow guiding head cavity is arranged, this cavity body is an annular seal space, in this cavity, be placed with a battery so that power supply to be provided, the bullet circular arc end face of flow guiding head has the effect that convection cell carries out uniform distribution and current stabilization, the annular fluid passage that forms between preceding flow guiding head and back flow guiding head and inner walls is a gasoline channel, the gasoline that adds passes through along this annular fluid passage, and promotes the turbine rotation.

Further set forth the utility model content below in conjunction with drawings and Examples.

Description of drawings:

Fig. 1 is the utility model symmetry sectional structure synoptic diagram.

Embodiment:

The utility model housing 1 is taked to be formed by two half elliptic tubular barrel butt joints, be front shell 3 and rear portion housing 13, front shell 3 connects inlet end 2, and rear portion housing 13 connects endpiece 14, and all inner measuring elements are convenient to be installed in the housing 1 by this docking structure.In housing 1, be provided with a turbine 10 and preceding turboshaft support 8 and back turboshaft support 11; Before insert respectively at turboshaft 14 two ends of turbine 10 in the back central axis hole 20 of the preceding central axis hole 19 of turboshaft support 8 and back turboshaft support 11, preceding turboshaft support 8 is taked cross structure with back turboshaft support 11, the cross two ends embed on the inwall of housing 1, and preceding turboshaft support 8 also can adopt with back turboshaft support 11 structures " bifurcation " shape or disk shape with holes.Flow guiding head 4 and back flow guiding head 12 before on preceding turboshaft support 8 and back turboshaft support 11, being sealedly connected with respectively; Between preceding flow guiding head 4 and back flow guiding head 12 and housing 1 inwall, form an annular fluid passage 6, in the sealed cavity body of preceding flow guiding head 4, be placed with battery 5; Be provided with a single-chip microcomputer metering display 17 in the outside of tubular shell, side at the single-chip microcomputer metering display is provided with a power switch 18, be furnished with four discontinuous magnet steel 9 at the middle part of turbine 10 blades, and be provided with a magnetic signal receiving trap 7 based on the Hall element principle in the inside of preceding turboshaft support; Single-chip microcomputer metering display 17 is connected with magnetic signal receiving trap 7 by the hole 16 of drawing that lead is passed on the tubular shell to be opened, the utility model is provided with the rubber ring 21 of an anti-leakage of oil that cooperates with nozzle at the entrance point 2 of housing, the socket 22 of this rubber ring is an introvert, can play the effect of anti-leakage of oil preferably, turning over the interlayer effect in this rubber ring is, when oil is filled it up with, this rubber ring is oppressed interlayer because there is oil to fill, this interlayer can be held the metal tube of nozzle tightly and prevent that oil from leaking.The utility model is provided with a bearing that cooperates with fuel tank cap 15 at the endpiece 14 of housing, the utility model can be fixed on the fuel tank, can conveniently observe when refueling; If without rubber ring 21 and bearing 15, the utility model also can independently use; But the inconvenience of exist using, for example hand is taken the utility model butt joint nozzle, has not only wasted staff but also leakage of oil easily, rubber ring and bearing have been installed after, be more conducive to the utility model and use, bearing 15 can be made generally the fuel tank cap interface at standard specification.The turboshaft head that the utility model is provided with in the middle of turbo blade is pointed, in order that reduce fluid resistance; Before flow guiding head and the back flow guiding head nose shape be bullet-shaped equally also be for reducing fluid resistance and playing the effect that convection cell carries out uniform distribution and current stabilization.
