Detailed description of the invention
Referring to figs. 1 through Fig. 5, the utility model embodiment is described further.
A kind of automatic mixing cup, comprise cup, bottom of cup is provided with a container, is provided with agitating device in container, and agitating device comprises impeller, motor, power supply, pressure switch;
The main shaft of motor extends in cup, and is fixedly connected with impeller;
Pressure switch comprises fixed part and movable part, be provided with spring between fixed part and movable part, spring one end is fixed on movable part, and the other end is fixed on fixed part, fixed part is provided with two fixing conducting end, and movable part is provided with two active conductive ends coordinated with fixing conducting end;
Two active conductive ends are communicated with, and one of them is connected with the positive pole of power supply to fix conducting end, and another is connected with the positive pole of motor; The negative pole of motor is connected with the negative pole of power supply.
By adopting technique scheme, be communicated with between two movable stiff ends, the positive pole of power supply is connected with one of them fixing conducting end, another fixing conducting end is connected with the positive pole of motor, the negative pole of motor is connected with the negative pole of power supply, so, just can form a loop; Above-mentioned movable part stretches out the bottom of storage tank under the action of the spring, and now two active conductive ends do not contact with two fixing conducting end, and so above-mentioned loop is not conducting, and that is motor can not rotate; When cup is put on the table, movable part will be retracted in container, so, active conductive end will contact with fixing conducting end, and so above-mentioned loop will conducting, and now motor just can rotate, and drive the wheel rotation in cup, so, just can realize stirring.
Preferably, be provided with a battery case in container, power supply is dry cell.Like this when electric quantity of power supply is not enough, continuous energy can be carried out by changing battery very easily.
Preferably, be also provided with a smart circuit in container, smart circuit comprises liquid level sensor, main control unit and voltage transformation unit; Liquid level sensor is connected to main control unit, and equal to the distance of bottom of cup with impeller tip to the distance of bottom of cup; Main control unit comprises control chip and gauge tap, and main control unit comprises control chip and gauge tap, and gauge tap is serially connected with between the negative pole of motor and the negative pole of power supply; Voltage transformation unit, transforming circuit be connected with power supply with by the voltage transition of power supply for intelligent cell can voltage.
By this preferred version, liquid level sensor is arranged on impeller to the identical height of the distance of bottom of cup, so when the liquid level in cup is lower than the height of impeller relative to bottom of cup, liquid level sensor will produce a signal will send control chip to, after control chip receives this signal, gauge tap will be disconnected, and then above-mentioned loop is just cut-off, so now impeller will stop operating, and that is agitating device can stop stirring.This is because when the liquid level in cup is lower than above-mentioned height, so impeller does not have mixing effect to the liquid in cup, if agitating device also works on, the waste causing electric quantity of power supply will be wasted, therefore, after above-mentioned setting, just can save the electricity of power supply.
In this preferred version, because the voltage of the power supply of dry cell composition can not directly as the operating voltage of this smart circuit, therefore, smart circuit comprises a voltage transformation unit, and then can be the operating voltage (5V) of intelligent cell by the voltage transition of power supply, voltage transformation unit is formed primarily of micro-pressure-difference voltage-stablizer TPS76350, the unstability voltage of this voltage-stablizer only has 180mV ~ 300mV, that is it can input voltage be low to moderate 5.3V even 5.18V time still guarantee the 5V voltage of stable output, its maximum input voltage 10V, maximum output current 150mA;
Gauge tap is PMOS, and it has grid, source electrode and drain electrode, and in this preferred version, this grid is connected to control chip, source electrode is connected to the negative pole of motor, and drain electrode is connected to battery at negative pole; Its operation principle, when control chip receives the signal that liquid level sensor sends, can export a high level to the grid of NMOS tube, and then make PMOS be in cut-off state, so, the negative pole of motor and the negative pole of power supply are just disconnected, thus impeller stops stirring.
In the present embodiment, main control unit is single-chip microcomputer, and model is AT89C51, and it has abundant input/output function, can meet the functional requirement of the present embodiment completely.
Preferably, the top of active conductive end and fixing conducting end is semicircular structure, and has elasticity.The object that employing designs like this is the contact effect in order to strengthen between two kinds of conducting end, prevents the situation occurring loose contact between two kinds of conducting end, this makes it possible to the stability improving loop, thus ensures the steady operation of agitating device.
