Water inflow control device with time delay function

Abstract

The invention discloses a water inflow control device with a time delay function. The device comprises: a first water outlet channel, which is communicated with a water inlet channel and can control water supply to a closestool water tank; a small water tank, which is equipped with a water storage cavity and a water channel that communicates the water storage cavity with the closestool water tank;a water stop unit, which comprises a small floating barrel that floats up or falls down along with the water level in the water storage cavity so as to control opening and closing of the first wateroutlet channel; a control unit, which controls the small floating barrel for keeping in a falling state under the action of water pressure of the first water outlet channel when water enters the waterinlet channel and the first water outlet channel is opened, thus keeping the first water outlet channel open, and which resets after the water inlet channel stops water so that the small floating barrel floats upwards along with the water level in the water storage cavity to close the first water outlet channel. According to the scheme, the control unit is disposed to enable delayed floating of the small floating barrel, the water inflow control device can have sufficient water supply time for the closestool water tank, the water level of the closestool water tank stably rises, the problem that the water inflow control device does not stop water is prevented, and the structure is simple.

Description

technical field [0001] The invention relates to a water inflow control device with a delay function. Background technique [0002] In the prior art, a water inlet valve and a water inlet control device are installed in the toilet water tank. The water inlet valve supplies water to the water tank or supplies water to the outside of the water tank under the action of the water inlet control device. The water inlet control device usually includes a control unit and a stop. The water unit also includes a first water outlet channel for water supply to the toilet tank, and the water stop unit is used to control the opening and closing of the first water outlet channel. The control unit includes a small water tank connected with the toilet tank and a small The floating barrel drives the water stop unit to control the opening and closing of the first water outlet channel. However, when the flow rate of water entering the small water tank is too fast or the water pressure is too high...

[0002] In the prior art, a water inlet valve and a water inlet control device are installed in the toilet water tank. The water inlet valve supplies water to the water tank or supplies water to the outside of the water tank under the action of the water inlet control device. The water inlet control device usually includes a control unit and a stop. The water unit also includes a first water outlet channel for water supply to the toilet tank, the water stop unit is used to control the opening and closing of the first water outlet channel, the control unit includes a small water tank connected with the toilet tank and a small The floating barrel drives the water stop unit to control the opening and closing of the first water outlet channel. However, when the flow rate of water entering the small water tank is too fast or the water pressure is too high, the water level in the small water tank will rise higher, and the small floating barrel will Floating ahead of time, the first water outlet channel is closed in advance, that is, the water level of the water tank cannot reach the water stop level, and the water in the water inlet valve has been flowing to the outside of the water tank, causing the water inlet valve to not stop
