Detailed Description
The invention is further explained in detail with the attached drawings and the embodiments;
referring to fig. 1 to 6, a toilet bowl drainage device according to an embodiment of the present invention includes:
a water tank (not shown);
the water discharge valve 10 is arranged in the water tank, the water discharge valve 10 comprises a valve body 11 provided with a water outlet 1111, a valve core 12 movably arranged in the valve body 11 and matched with the water outlet 1111 in an opening and closing mode, and a floating barrel 13 movably arranged in the valve body 11, the floating barrel 13 and the inner wall of the valve body 11 enclose a negative pressure cavity 14, the negative pressure cavity 14 is communicated with the inner cavity of the water tank, and the floating barrel 13 is in transmission connection with the valve core 12;
the water pump 20, the inlet 21 of the water pump 20 is communicated with the negative pressure cavity 14, the outlet 22 of the water pump 20 is communicated with the flushing waterway of the toilet, when the water pump 20 is started, the water in the water tank is pumped to the flushing waterway through the negative pressure cavity 14, and negative pressure is formed in the negative pressure cavity 14, so that the floating barrel 13 can float under the action of buoyancy to drive the valve core 12 to open the water outlet 1111; after the water level in the water tank is lowered to a predetermined position, the float tub 13 is lowered by gravity to drive the valve core 12 to close the water outlet 1111.
In this embodiment, after the water level in the water tank is lowered to the point that the air in the water tank enters the negative pressure cavity 14, and the buoyancy of the float bucket 13 is not enough to support the gravity of the float bucket 13 and the valve core 12, the float bucket 13 falls under the action of the gravity of the float bucket 13 and the valve core 12. After the negative pressure chamber 14 is filled with air, the air can counteract the negative pressure, so that the floating barrel 13 can reliably fall.
Specifically, in this embodiment, the top end of the float bucket 13 is closed, the bottom end is open, the top wall of the float bucket 13 and the inner wall of the valve body 11 enclose a negative pressure cavity 14, an overflow gap 15 is formed between the side wall of the float bucket 13 and the inner wall of the valve body 11, and water and air in the water tank flow into the negative pressure cavity 14 through the overflow gap 15. Therefore, the water flow in the overflow gap 15 flows from bottom to top, which can further assist the floating of the floating barrel 13 and ensure the floating barrel 13 to float smoothly; in addition, the air in the water tank flows into the negative pressure cavity 14 through the overflowing gap 15, so that the air inlet is positioned at the lower position of the water tank, the water outlet 1111 is closed after the water in the water tank is drained quickly, and the water drainage quantity is larger.
In this embodiment, the valve body 11 includes a base 111 and an upper cover 112, the water outlet 1111 is disposed on the base 111, and the base 111 and the upper cover 112 are connected to form an inner cavity for accommodating the float bowl 13.
In this embodiment, a water pump mounting seat 23 is further fixed on one side of the upper cover 112, and the water pump 20 is mounted on the water pump mounting seat 23. The water pump mounting base 23 is fixed on the upper cover 112, so that the whole drainage device is more compact and faster to mount. In other embodiments, the water pump mounting seat 23 can be fixed on one side of the base 111, and the whole drainage device can be more compact and faster to install.
In this embodiment, a guide post 131 extends upward from the top wall of the float bowl 13, a guide hole 1121 penetrating up and down is formed in the upper cover 112, and the guide post 131 is matched with the guide hole 1121, so that the float bowl 13 can reliably and smoothly slide up and down in the valve body 11.
In this embodiment, the top end of the float bucket 13 is closed, the bottom end is open, the top wall of the float bucket 13 and the inner wall of the valve body 11 enclose a negative pressure cavity 14, an annular partition plate 132 is arranged in the float bucket 13, the partition plate 132 divides the inner cavity of the float bucket 13 into a central cavity and an outer annular cavity surrounding the central cavity, and the valve core 12 is fixed on the partition plate 132 and covers the bottom end opening of the central cavity.
Preferably, in this embodiment, the negative pressure chamber 14 is located below the operating water level of the water tank. This makes it possible to make the negative pressure chamber 14 in a full water state in an initial state of not draining water, so that it is easier to form a sufficient negative pressure.
The flushing waterway of the toilet may include a brush ring waterway 30 and a spray waterway 40, referring to fig. 5, the outlet 22 of the water pump 20 of the present invention may communicate with the brush ring waterway 30 of the toilet to supply washing water to the inner peripheral wall of the bowl 50 of the toilet; alternatively, referring to fig. 6, the outlet 22 of the water pump 20 may be in communication with the jet path 40 of the toilet to provide jet water to jet holes 51 provided in the bottom of the bowl 50 of the toilet.
Referring to fig. 3, when the toilet drainage device is at the beginning of pumping and the drainage port 1111 is not opened, the pump 20 pumps water from the negative pressure chamber 14 to the flushing waterway of the toilet, and water in the tank is replenished into the negative pressure chamber through the overflow gap 15 and is continuously pumped out of the negative pressure chamber by the pump 20 to provide a sufficient flushing volume to the flushing waterway of the toilet (the curve with arrows in fig. 3 indicates the path of the pumping water flow of the pump 20). Meanwhile, as negative pressure is formed in the negative pressure chamber 14, the float 13 can float under the action of the negative pressure and its own buoyancy and drive the valve core 12 to open the water outlet 1111 for water discharge, as shown in fig. 4. When the water level in the water tank drops to the bottom end of the overflowing gap 15, air in the water tank enters the negative pressure cavity 14 from the overflowing gap 15, so that negative pressure in the negative pressure cavity 14 is counteracted, and meanwhile, when the buoyancy of the floating bucket 13 is not enough to support the gravity of the floating bucket 13 and the valve core 12, the floating bucket 13 falls under the gravity action of the floating bucket 13 and the valve core 12 and drives the valve core 12 to close the water outlet 1111 again, so that water drainage is finished.
According to the water discharge valve, the negative pressure cavity is adopted to control the floating barrel to lift, when water in the negative pressure cavity is pumped out by the water pump, negative pressure is formed to enable the floating barrel to float so as to drive the valve core to open the water discharge port for water discharge, when air enters the negative pressure cavity, the air counteracts the negative pressure so that the floating barrel can fall so as to drive the valve core to close the water discharge port, and compared with the power required by the water pump for pumping water in the negative pressure cavity in the prior art, the power required by the water pump for driving the hydraulic water discharge valve is greatly reduced, so that the power requirement on the water pump can be effectively reduced, the cost of the water pump is reduced, the structure of the water discharge valve is simple, the cost of the water discharge valve is greatly reduced, and the cost of the whole water discharge device is reduced.
The above-mentioned embodiments are only used to further illustrate the present invention, but the present invention is not limited to the embodiments, and any simple modifications, equivalent changes and modifications made to the above-mentioned embodiments according to the technical essence of the present invention fall within the protection scope of the technical solution of the present invention.
