6. The water supply device according to claim 1, wherein the control valve comprises a first control valve and a second control valve, wherein the first control valve is used for controlling the water conveying pipeline to open and close, and the second control valve is used for controlling the water replenishing operation of the water tank.
7. The water supply device as claimed in claim 4, wherein the second control valve comprises a ball float valve, the ball float valve comprises a valve body and a ball valve, the ball valve acts on the liquid level of the water tank and is connected with the valve body through a water conveying pipe, and a third control valve is mounted on the water conveying pipe;
the two ends of the valve body are respectively connected with the water conveying pipeline and the water tank, two water storage cavities connected through openable water conveying ports are arranged inside the valve body, and the water conveying ports are controlled to be opened and closed through a third control valve and/or a ball valve so as to control the second control valve to be opened and closed.
8. The water supply apparatus as claimed in claim 1, wherein an overflow pipe is provided at an upper portion of the water tank, and water higher than a set water level in the water tank is discharged through the overflow pipe.
9. The water supply device according to claim 1, wherein the water tank is provided with a liquid level alarm, and the liquid level alarm gives an alarm when the liquid level in the water tank is lower than a preset low level.
10. A water supply method applied to the water supply apparatus according to any one of claims 1 to 7, comprising the steps of:
opening the control valve to a set opening degree, so that water in the water supply pipeline is conveyed to the water conveying pipeline;
when water is supplied, the liquid level sensor measures the liquid level of the water tank to the idle water supplementing liquid level, water is supplemented to the water tank through the control valve, and after the water is supplemented to the preset liquid level, the control valve is closed to complete water supplementing;
the control valve is controlled to be opened in a set time period before the water supply peak, the water tank is supplied with water to a preset liquid level in a preset water supply time period before the peak, and the control valve is closed to complete water supply of the water tank.
