A foot-operated pre-flush toilet valve

Abstract

The invention discloses a treadle-operated pre-toilet-flushing valve. A horizontal pipe (2) and a vertical pipe (3) are metal tubes, the inner diameters of the horizontal pipe (2) and the vertical pipe (3) are same, the axis of the horizontal pipe (2) and the axis of the vertical pipe (3) are perpendicular to each other, and a pipe cap (4) is arranged at the upper end face of the vertical pipe (3). A valve rod (6) is installed at the upper end of a ball valve (1), and the valve rod (6) penetrates through the pipe cap (4) and can move up and down in a hole of the pipe cap (4). A support (11) is fixed to the horizontal pipe (2) and is sequentially provided with a supporting column (8), a supporting pin (9) and a torsion spring (15). One end of a foot lever (7) penetrates through a square hole in the upper end of the supporting column (8) and is hinged to the valve rod (6), the other end of the foot lever (7) is sequentially provided with two pedals including a pre-flushing pedal (12) and a flushing pedal (13). The pre-toilet-flushing valve is simple in structure and convenient to operate, has a squatting pan pre-flushing function, and does not waste many water resources.

Description

technical field [0001] The invention relates to a valve, in particular to a foot-operated toilet flushing valve with a preflushing device. Background technique [0002] In some outdoor toilets, people usually only use them at certain intervals, especially in summer, after a long period of wind and sun, the surface of the porcelain squatting pan is dry, and once it comes into contact with feces, the feces will stick firmly. On the surface, it is difficult to rinse with water, and in desperation, it can only be rinsed several times. As a result, a large amount of water resources are wasted, but it is still difficult to rinse, which makes the hygienic environment worse. If you use a small amount of water to pre-rinse for a little longer before use, a water film will form on the surface of the porcelain squatting toilet, and the feces will not stick firmly, and it is easy to rinse clean without wasting more water resources.

[0002] In some outdoor toilets, people usually only use them at certain intervals, especially in summer, after a long period of wind and sun, the surface of the porcelain squatting pan is dry, and once it comes into contact with feces, the feces will stick firmly. On the surface, it is very difficult to rinse with water. In desperation, it can only be rinsed many times. As a result, a lot of water resources are wasted, but it is still difficult to rinse, which makes the sanitary environment worse.
