2. Because the filter screen separates the inner cavity of the shell completely, impurities in water enter the drainer to be blocked on the filter screen completely, so that the durability of the filter screen is poor.
Disclosure of Invention
The utility model aims to solve the technical problem of providing the water drainer which is provided with the filter screen arranged at a position close to the water drain outlet, does not separate the inner cavity of the whole shell, has better filtering effect and durability and can avoid the failure of the whole water drain function.
The technical scheme of the utility model is that the drainer with the following structure is provided, and comprises a shell with an inner cavity, wherein the bottom of one end of the shell is provided with a water outlet, the top of the other end of the shell is provided with a pressure relief opening, the middle of the shell is provided with a water inlet, and the bottom of the shell is provided with a drain outlet; a floating ball mechanism is arranged in the shell and is connected with a drain valve in the drain outlet, and the floating ball mechanism drives the drain valve to open and close; the method is characterized in that: the filter screen is arranged in the shell, the filter screen is close to the water outlet, and water in the shell is discharged from the water outlet through the filter screen.
And a distance is arranged between the top of the filter screen and the bottom of the inner cavity of the shell.
The bottom of the filter screen and the edge of the side face are in sealing connection with the shell.
The inside of the shell is provided with a long groove, and the bottom and the side edges of the filter screen are embedded in the long groove.
The floating ball mechanism comprises a floating ball and a connecting rod, one end of the connecting rod is connected with the floating ball, the other end of the connecting rod is connected with the drain valve, and the connecting rod is a lever and is connected to the shell through a rotating shaft.
And a distance is arranged between the top of the filter screen and the bottom of the connecting rod.
The shell comprises a left shell and a right shell, and sealing rings are arranged on the connecting end faces of the left shell and the right shell.
The long groove is U-shaped, the bottom is positioned at the bottom of the inner wall of the shell, the two sides of the long groove are positioned at the inner side of the shell, and the height of the long groove is consistent with that of the filter screen.
After adopting the structure, the utility model has the following advantages:
1. the filter screen is arranged at the position of the water outlet close to the inside of the shell, and the inside diameter of the water outlet is only a few millimeters, so that the phenomenon that the water outlet is blocked by impurities and cannot drain water can be avoided, and the whole drainer loses the drainage function.
2. Because the drive end of the connecting rod of drain valve and floating ball mechanism is located between filter screen and outlet, after filtering impurity through the filter screen, can avoid impurity to block the drive end of floating ball mechanism and dead and can't drive the drain valve to can guarantee that the connecting rod normally drives the drain valve.
3. Because there is the interval between the top of filter screen and the top of casing inner chamber, namely the filter screen does not separate whole casing inner chamber. Under normal conditions, water flowing into the bottom surface of the shell passes through the filter screen and is normally discharged from the drain valve. Once the filter screen is blocked, water can also overflow the filter screen and then be discharged from the drain valve, so that double protection can be achieved, and the service life is effectively prolonged.
