Problems solved by technology

However, conventional sensor-type flushing system for a toilet tank needs the sensor to be embedded in a wall, so it needs work to break or dig the wall and repair it again, not convenient for use.
If the wireless sensor is used with an independent power, it must use a battery, and then the battery has to be replaced with new ones frequently, in addition, the wires have to be exposed out to impair the appearance or a wall has to be dug for embedding them.

Embodiment Construction

[0023]A preferred embodiment of a sensor-type flushing system for a toilet tank in the present invention, as shown in FIGS. 1, 2 and 3, includes a toilet tank 10, a pressured tank 20, a switch valve 30, an electromagnetic valve 40, an operational device 50, a sensor 60, a power circuit 70 and a control case 80 as main components.

[0024]The toilet tank 10 shown in FIG. 3 is made of porcelain, provided with a hollow space 11 for receiving the pressured water tank 20 therein.

[0025]The pressured tank 20 is deposited in the toilet tank 10, having a store space 21 for storing pressured water therein, and a drain valve 22 fixed in the bottom for the pressured water to flow through for flushing the toilet bawl.

[0026]The switch valve 30, as shown in FIGS. 5 and 6, is positioned between the toilet tank 10 and the pressured tank 20, consisting of a front housing 31, a rear housing 32 and a stop valve 33. The front housing 31 is provided with an insert hole 311 in the front side, and an inlet 31...

Abstract

A sensor-type flushing system for a toilet tank includes a pressured tank installed in a toilet tank, both a switch valve and an electromagnetic valve connected to the pressured tank. The pressure tank is provided with a drain valve so that pressured tater stored in the pressured tank may be made to flow out of the drain valve to flush pressed water in the toilet bawl by handling manually an operational device set on an outer wall of the toilet tank. Further, the operational device is provided with a sensor, which senses a human body and emits and receives signals to electrically open the electromagnetic valve so as to open the drain valve for flushing pressured water into the toilet bawl. Thus the sensor-type flushing system has two functions of manual and automatic flushing.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to a sensor-type flushing system for a toilet tank, particularly to one operable both automatically and manually.[0003]2. Description of the Prior Art[0004]Conventional toilet tanks have been commonly operated manually, needing a little force and not so hygienic. So sensor-type flushing systems for a toilet tank have been made and in use widely, and one of them is provided with a sensor to be embedded in a wall, and the sensor is electrically connected with the toilet tank with wires also embedded in the wall. The other is provided with a wireless sensor also embedded in a wall, and a receiver installed in the toilet tank so that the sensor can command the receiver to carrying out flushing by means of infrared ray when it senses a person stands before the toilet or leaves the toilet.[0005]However, conventional sensor-type flushing system for a toilet tank needs the sensor to be embedded in a wall,...
