Problems solved by technology

The existing rotary valves have the following deficiencies: 1. Since the transmission shaft and rocker cannot be automatically reset, they are in different positions in different states, which is inconvenient for users to operate; 2. Since the water body, transmission shaft and rocker are fixed together, the Whether the rotation of the water separation body is accurate or not is all controlled by the joystick. When the user rotates, there may be over-rotation or non-rotation, etc., and the switching accuracy cannot be guaranteed.

Abstract

The invention discloses an automatic return valve, which comprises a fixed unit, a water distribution body, a stop mechanism, a transmission shaft and a clutch mechanism. The fixed unit is provided with an inlet waterway and at least two outlet waterways. The water distribution body is rotatably installed in the fixed unit. The outlet waterways are switched and are communicated with the inlet waterway through the relative rotation between the water distribution body and the fixed unit. An external ratchet is arranged on the external rotary surface of the water distribution body. The stop mechanism is connected with the fixed unit and acts on the external ratchet. The transmission shaft is rotatably installed on the fixed unit and is provided with a control end and a transmission end, wherein the control end is arranged outside the fixed unit and the transmission end is arranged in the fixed unit. The clutch mechanism is connected between the transmission end of the transmission shaft and the internal rotary surface of the water distribution body. A return elastic body is connected between the transmission shaft and the fixed unit. The invention has the advantages that the automatic return is realized, the transmission shaft is at the same position no matter which state a shower head is in, and thereby the user operation is facilitated.

Description

technical field [0001] The invention relates to an automatic reset valve. Background technique [0002] The existing rotary valve comprises a fixed unit, a water diversion body, a transmission shaft and a rocker. The fixed unit has a water inlet and at least two water outlets. The water-distributing body is rotatably mounted in the fixed unit, and the water-distributing body and the fixed unit are rotated relative to each other to switch the water outlet and connect the water inlet. The transmission shaft has a fixed end and a control end, the fixed end is fixedly connected to the water diversion body, and the control end protrudes from the fixed unit and is fixedly connected to the rocker. The existing rotary valves have the following deficiencies: 1. Since the transmission shaft and rocker cannot be automatically reset, they are in different positions in different states, which is inconvenient for users to operate; 2. Since the water body, transmission shaft and rocker a...
