Detailed ways

In order to make the technical means realized by the utility model, creation features, goals and effects easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

As shown in accompanying drawings 1 and 2, the lazy alarm clock piggy bank includes an LCD display 1, a piggy bank main body 2, a twelve-key keyboard 6, an infrared sensor, and an infrared sensor control circuit. The piggy bank main body 2 is hollow, and the piggy bank main body 2 The front is provided with an LCD display 1 and a twelve-key keyboard 6, the LCD display 1 is located above the twelve-key keyboard 6, and the top surface of the piggy bank main body 2 is respectively provided with a first coin insertion opening 3 and a second coin insertion opening 4 , the third coin slot 5, the bottom surface of the piggy bank main body is provided with a coin take-out port 7, and the first coin slot 3, the second coin slot 4, and the third coin slot 5 are respectively provided with two infrared sensors .

As shown in FIG. 3 , the infrared sensor includes an infrared sensor emitting tube 8 and an infrared sensor receiving tube 9 , and the infrared sensor emitting tube 8 and the infrared sensor receiving tube 9 are respectively located on both sides of each coin insertion opening. The distance between the two infrared sensors of each coin insertion port is different, and the distance between the two infrared sensors is equal to the diameter of the coin that the coin insertion port needs to insert. The first coin insertion port 3, the second coin insertion port 4, the third coin insertion port The coin slot 5 corresponds to inserting one yuan, five cents or a dime respectively, and it is confirmed that the coin has been inserted if and only when the two infrared sensors of the same coin slot all sense the object input.

As shown in Figure 4, the infrared sensor control circuit includes a voltage stabilizing chip 10, a single-chip microcomputer 11, a buzzer 12, a power supply, the positive pole of the power supply is connected to the voltage stabilizing chip 10, and the voltage stabilizing chip 10 is connected to the power supply pin of the single-chip microcomputer 11 , the negative pole of the power supply is connected to the reference ground pin of the single-chip microcomputer 11 and grounded, and the infrared sensor receiving tube 9, the twelve-key keyboard 6, the LCD display 1, and the buzzer 12 are connected to the I/O port of the single-chip microcomputer 11.

The voltage stabilizing chip of the present utility model can be selected the voltage stabilizing chip of LM7805 model, and the single-chip microcomputer can be selected 51 series single-chip microcomputers such as the single-chip microcomputer of AT89C52 model for use.

The working process of the present utility model is as follows: when the alarm clock works, the LCD display 1 displays the time and date, and when the alarm clock time is reached, the buzzer 12 buzzes, and the display on the LCD display 1 requires the user to input The denomination and quantity of the coins, the specific denomination and quantity are randomly generated by the control of the single-chip microcomputer 11, and the denominations of the coins are one yuan, five jiao or one jiao, corresponding to the first coin insertion port 3, the second coin insertion port 4, and the third coin insertion port 5 respectively.
