Abstract

The invention provides a toy for a pet cat and a working method thereof, and the technical points are as follows: in the starting state, the MCU controls the motor to start, drives the simulated mouse to drill out and run in the lower part of the cover body in a non-uniform drilling way, and simultaneously sends out a mouse simulated cry to attract the attention of the pet cat; after the state lasts for a certain time T1, the MCU controls the motor and the loudspeaker to stop working, simultaneously starts the infrared sensor, detects whether a pet cat approaches, simulates the mouse to restart running and call if the infrared sensor is triggered in the process, and keeps the motor and the loudspeaker in the stop working state until the set time T2 is finished if the infrared sensor is not triggered, and automatically restarts the simulated mouse to run and call. The simulated mouse can simulate the situation that the mouse drills out under the cover body at a non-uniform speed and send out a mouse simulated cry, so that the attraction to pet cats is very strong; whether the pet cat is close to or not is automatically detected by arranging the infrared sensor, and the simulated mouse is automatically started and stopped, so that the cat can be automatically teased under the unmanned condition.

Further, the simulated mouse is provided with an independent battery, an MCU control board, a switch, and LED lights located at the eyes, and the MCU control board controls the intermittent point changes of the LED lights to simulate the blinking effect of the mouse. A current detection circuit for monitoring the change of the motor torque is also provided between the motor and the MCU; the MCU monitors the change of the motor torque to control the voice IC to emit different analog sounds through the horn.

A working method of a pet cat toy, including the following procedures:

S1: The MCU scans the key to detect the state of the start-stop switch; if it is turned on, it will continue to run the program; if it is turned off, it will enter the shutdown process, and the motor, infrared sensor and speaker will all stop working;

S2: When the operation starts, the MCU controls the motor to start, and the rotating body drives the simulated mouse to run forward and backward at random. At the same time, the MCU controls the horn to emit a simulated sound of the mouse to attract the attention of the pet cat; the duration of this program T1 is set by the MCU;

S3: When the time T1 set by the S2 program ends, the MCU controls the motor and the horn to stop working; at the same time, the MCU controls the infrared sensor to turn on to detect whether there is a pet cat approaching the detection area, and the duration T2 of the infrared sensor is set by the MCU; if the process If the infrared sensor is not triggered during the process, the motor and the horn will remain in the stop working state; if the infrared sensor is triggered during the process, it will return to the S2 program;

S4: In the S3 procedure, if the infrared sensor is not triggered at the end of the set time T2, return to the S2 procedure.

Further, in the S2 program, when the simulated mouse is caught by the pet cat, the torque of the motor driving it to run suddenly changes. After the MCU monitors this change through the current detection circuit, it controls the voice IC to issue the simulated mouse through the speaker. screams.

Its working principle is: after the start-stop switch is activated, the simulated mouse will run in and out at a non-uniform speed under the drive of the motor, and at the same time make a simulated sound to attract the pet cat; Whether it is approaching, the simulated mouse will stop running and making sound; at this time, the infrared sensor will be turned on to detect whether there is a pet cat approaching. When the pet cat approaches, the simulated mouse will restart to attract the pet cat; if there is no pet cat approaching , you can set a longer period of time to restart the simulated mouse, and continue to cycle until the start-stop switch is turned off.

Its beneficial effects are as follows: 1. The simulated mouse can simulate the situation that the mouse drills in and out at a random speed under the cover and emits a simulated sound of the mouse, which has a high degree of simulation and is very attractive to pet cats; 2. By setting the infrared The sensor automatically detects whether the pet cat is approaching and automatically starts and stops the simulated mouse, which can realize the function of automatically teasing the cat when there is no one there.
