Abstract

The present disclosure provides a pet toilet and a control method thereof. The pet toilet includes a circuit board, an identification module, a base and a roller rotatably arranged on the base. The identification module is electrically connected to the circuit board to acquire an image, and the circuit board controls the roller to rotate after the identification module identifies that a pet has left the roller. Therefore, the circuit board controls the roller to rotate after the identification module identifies that the pet has left the roller, so as to solve the problem of misjudgment easily caused by the fact that only a weighing sensor is used to perform waste cleaning in the prior art. The probability of misjudgment on the defecation of a pet is effectively reduced. The number of times of rotation of the roller is reduced. The power consumption is reduced.

Claims (47)

1 . A control method applicable to a pet toilet, the pet toilet comprising a circuit board, an identification module, a base, and a roller rotatably arranged on the base,

wherein the identification module is electrically connected to the circuit board to acquire an image inside the roller by the identification module, and the circuit board controls the roller to rotate after the identification module identifies that a pet has left the roller;

the pet toilet further comprising a detection module electrically connected to the circuit board to detect presence of an object, wherein the circuit board controls the roller to stop rotating according to a signal fed back by the detection module; wherein the control method comprises steps of:

acquiring the image inside the roller by the identification module;

identifying, by the circuit board based on the image, that a pet has entered the roller;

identifying, by the circuit board based on the image, that the pet has left the roller; and

performing a waste cleaning action to control the roller to rotate to discharge waste after identifying that the pet has left the roller;

wherein in the step of performing the waste cleaning action, the control method further comprises steps of:

receiving an electrical signal fed back by the detection module; and

controlling the roller to stop rotating when the electrical signal fed back by the detection module has been received;

wherein before the step of performing the waste clearing action, the control method further comprises a step of:

identifying, through the identification module, that no pet enters the roller within a first preset time period,

wherein after the step of identifying, through the identification module, that the pet has entered the roller, the control method further comprises a step of:

starting a timer, and forming first time;

wherein after the step of identifying, through the identification module, that the pet has entered the roller, the control method further comprises a step of:

recording first data, wherein the first data comprises a number of times of entry and a quantity of pets that have entered the roller for defecation; the number of times of entry is a number of times of the pet entering the roller within one waste cleaning cycle; the quantity of pets that have entered the roller for defecation is an actual quantity of pets that have entered the roller and defecated plus 1; and the actual quantity of pets that have entered the roller and defecated is a quantity of pets that have accumulatively entered the roller within one waste cleaning cycle and stayed for a second preset time period.

2 . The control method for the pet toilet according to claim 1 , wherein after the step of identifying, through the identification module, that the pet has left the roller, the control method further comprises a step of:

matching the first data.

3 . A control method applicable to a pet toilet, the pet toilet comprising a circuit board, an identification module, a base, and a roller rotatably arranged on the base,

wherein the identification module is electrically connected to the circuit board to acquire an image inside the roller by the identification module, and the circuit board controls the roller to rotate after the identification module identifies that a pet has left the roller;

the pet toilet further comprising a detection module electrically connected to the circuit board to detect presence of an object, wherein the circuit board controls the roller to stop rotating according to a signal fed back by the detection module; wherein the control method comprises steps of:

acquiring the image inside the roller by the identification module;

identifying, by the circuit board based on the image, that a pet has entered the roller;

identifying, by the circuit board based on the image, that the pet has left the roller; and

performing a waste cleaning action to control the roller to rotate to discharge waste after identifying that the pet has left the roller;

wherein in the process of performing a waste cleaning action, the control method further comprises steps of:

receiving an electrical signal fed back by the detection module; and

controlling the roller to stop rotating when the electrical signal fed back by the detection module has been received;

wherein before the step of performing a waste clearing action, the control method further comprises a step of:

identifying, through the identification module, that no pet enters the roller within a first preset time period,

wherein after the step of identifying, through the identification module, that a pet has entered the roller, the control method further comprises a step of:

starting a timer, and forming first time;

wherein after the step of identifying, through the identification module, that the pet has left the roller, the control method further comprises steps of:

stopping the timer;

determining whether the first time is greater than a second preset time period; and

recording that a quantity of pets that have entered the roller for defecation is an actual quantity of pets that have entered the roller and defecated.

4 . The control method for the pet toilet according to claim 3 , wherein after the step of determining whether the first time is greater than the second preset time period, the control method further comprises a step of:

if no, subtracting the quantity of pets that have entered the roller for defecation by 1.

5 . The control method for the pet toilet according to claim 4 , wherein the pet toilet further comprises a weighing sensor for weighing, arranged on the roller or the base, wherein the circuit board is electrically connected to the weighing sensor;

before the step of starting the timer, the control method further comprises a step of: detecting, through the weighing sensor, that a weight increases;

before the step of stopping the timer, the control method further comprises a step of: detecting, through the weighing sensor, that the weight decreases;

wherein the first data further comprises a first weight.

6 . The control method for the pet toilet according to claim 5 , wherein before the step of performing the waste clearing action, the control method further comprises a step of:

within the first preset time period, identifying, through the identification module, that a pet has entered the roller, and starting to perform the control method from the step of identifying, through the identification module, that a pet has entered the roller;

or, within the first preset time period, detecting, through the weighting sensor, that a weight increases, and starting to perform the control method from the step of detecting, through the weighting sensor, that a weight increases.

7 . The control method for the pet toilet according to claim 6 , wherein after the step of performing the waste cleaning action, the control method further comprises a step of:

clearing the first time and the first data.
