Abstract
The utility model relates to a daily necessity, in particular to a measuring piggy bank, comprising a hollow piggy bank body which is provided with a slit. The bottom of the piggy bank body is fixedly connected with a base, a voltage dependent resistor is arranged between the piggy bank body and the base, an ammeter is inlaid in the front of the piggy bank body, and the voltage dependent resistor and the ammeter are connected in a power supply circuit in series. The measuring piggy bank uses a weighting method to approximately estimate the number of the coins in the piggy bank, has simple structure and low cost of production, and completely meets the requirement for a cheap piggy bank without high measuring requirement, in spite of certain errors.
Description
Technical field
The utility model relates to a kind of articles for daily use, is the metering penny bank specifically.
Background technology
Common penny bank is only with the storage coin, but can not show the quantity of coin.The precise counting device can't be used on the cheap penny bank owing to complex structure.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, metering penny bank that can show the roughly quantity of coin in the penny bank.
For achieving the above object, this uses the following technical scheme of novel employing:
Metering penny bank described in the utility model comprises the tank body of hollow, have coin slot on the tank body, it is characterized in that: the bottom of tank body is fixedly connected with base, has piezo-resistance between tank body and the base, the front of tank body is inlaid with ammeter, and piezo-resistance and ammeter are connected in the power circuit.
The method that the utility model utilization is weighed is roughly estimated the quantity of coin in the penny bank, and is simple in structure, production cost is low.Though certain error is arranged, the cheap penny bank not too high for measuring requirement meets the demands fully.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 is a circuit diagram of the present utility model.
The specific embodiment
As shown in drawings, metering penny bank described in the utility model comprises the tank body 1 of hollow, has coin slot on the tank body 1.The bottom of tank body 1 is fixedly connected with base 2, has piezo-resistance 4 between tank body 1 and the base 2, and the front of tank body 1 is inlaid with ammeter 3, and piezo-resistance 4 and ammeter 3 are connected in the power circuit.Piezo-resistance 4 is subjected to the weight of tank body 1, and according to the size of pressure, the resistance of piezo-resistance 4 changes, and the electric current in the circuit just changes, and people just can judge the quantity of coin in the penny bank substantially according to the reading of ammeter 3.
