Rotary connection structure, valve control device and water purification faucet

Abstract

The invention discloses a rotary connection structure, a valve control device and a water purification faucet. In the rotary connection structure, a body is provided with a shaft hole taking a first shaft as an axis and provided with an opening in an end face and a rotary limiting block; a rotating shaft is inserted into the shaft hole and is rotationally clamped with the body; a handle and the rotating shaft are inserted in a rotation-stopping mode in the first axis direction, and an abutting block is arranged on the outer wall of the handle; the abutting block is configured to abut against the rotary limiting block to limit the rotating shaft to exit the rotation clamping connection when the handle drives the rotating shaft; and a shell is fixedly connected with the body and is in insertion fit with the handle in a relatively rotating mode in the direction perpendicular to the first shaft. The valve control device and the water purification faucet adopt a water path switching structure to realize water path switching. According to the rotary connection structure, the valve control device and the water purification faucet, a valve element has a stable relative position relation relative to a valve seat, and the situation that the water path control function is invalid can be avoided; and furthermore, the production cost and the installation cost can be controlled easily.

Description

technical field [0001] The present application relates to the field of water outlet devices, in particular to a rotating connection structure, a valve control device and a water purification faucet. Background technique [0002] In the prior art, the opening and closing or switching of the waterway in the water outlet device (ordinary faucet, shower or clean water faucet, etc.) is mostly realized by setting a control valve. The control valve includes a valve seat, a valve housing and a valve core, and the valve core passes through the valve The shell is limited in the valve seat, and it is generally set to realize waterway control by rotating relative to the valve seat. The above-mentioned technical solution mainly has the following defects: the valve core is fixed by the valve shell, so once there is a dimensional error, assembly error or Deformation, the position of the valve core in the valve seat is uncertain, the positioning of the valve core is not reliable, and the co...
