Embodiment Construction

[0024] A drain valve for a non-spool type toilet with adjustable water output, comprising a button (2) arranged on a toilet tank, a drain valve body (1) and a hose (3) arranged at the bottom of the toilet tank; the drain valve body ( 1) Contains the push button mechanical transmission (4) and the rotary mechanical transmission.

[0025] The water inlet (31) of the hose (3) is arranged on the drain valve body (1), the water outlet of the hose (3) is connected with the water outlet of the water tank, and the middle part (32) of the hose is fixed on the drain valve body (1).

[0026] When the toilet is not in use, the initial state of the middle part of the hose (32) is above the liquid level of the water tank; when the button (2) is pressed, the vertical rod (21) arranged under the button (2) is in the position of the button mechanical transmission device (4). Driven, the middle part of the hose (32) is driven down. When the highest position of the middle part of the hose (32) d...

Abstract

The invention discloses a water-yield-adjustable drain valve for a valve-element-free closestool. The drain valve comprises a button arranged on a closestool water tank, a drain valve body arranged at the bottom of the closestool water tank and a hose. The drain valve body comprises a button mechanical transmission device and a rotary mechanical transmission device, and a water inlet of the hose is formed in the drain valve body. The water discharge amount is adjusted by adjusting the height of the position of the soft water inlet. The middle part of the hose is fixed on the button mechanical transmission device and is positioned above the liquid level of the water tank when the closestool is not used; when the button is pressed down, the whole hose descends below the liquid level of the water tank, and due to the siphon effect, even if the water level of the water tank descends below the highest position of the hose, water above the water inlet of the hose can be discharged. The closestool drain valve is not provided with a valve element, and the problem of water leakage caused by poor contact of the valve element of the closestool drain valve is solved.

Description

technical field [0001] The invention belongs to the technical field of toilets, and in particular relates to a drain valve for toilets. Background technique [0002] As the shortage of fresh water resources becomes more and more serious, people's awareness of environmental protection is becoming stronger and stronger, and they have become more aware of water consumption in daily life. There is also a demand for the water-saving performance of toilets to prevent excessive water use. [0003] The flushing volume of the existing toilet tank cannot be controlled at will. Usually, when the flush button is pressed, all the water in the toilet tank will be discharged from the water tank drain at once. Although it has a large flushing force, it is a waste of water. . [0004] At the same time, the existing toilet includes an inlet valve and a drain valve. The drain valve is generally made of a rubber plug, but sometimes there are foreign objects, misalignment, poor contact between ...
