AI Technical Summary

Technical Problem

When adjusting the water temperature, excessive torque in existing thermostatic valves can cause the entire valve to rotate, resulting in inaccurate water temperature adjustment. Furthermore, conventional knobs lack a limit mechanism, making them prone to causing burns due to misoperation.

Method used

A knob adjustment device is designed, including a mixing valve, a rotary adjustment component and a valve fixing component. The valve body circumferential rotation is restricted by the limiting structure of the valve fixing component, and the rotation stroke is controlled by the second limiting structure to prevent the thermostatic valve from deflecting as a whole and from being misoperated.

Benefits of technology

This effectively avoids scalding problems caused by inaccurate water temperature adjustment and misoperation, ensuring the accuracy and safety of water temperature adjustment.

Abstract

The application discloses a knob adjusting device and a cleaning machine, and relates to the technical field of electrical appliances, wherein the knob adjusting device comprises: a water mixing valve, the water mixing valve comprises a valve body and a valve core, the valve body is used for being installed on a water storage container, and the valve core is rotatably arranged on the valve body; a rotary adjusting assembly is in transmission connection with the valve core, the rotary adjusting assembly is used for rotating under the action of external force to drive the valve core to rotate; and a valve fixing piece is used for being connected and fixed with the water storage container, the valve fixing piece is provided with a first limiting structure matched with the valve body, and the first limiting structure is used for limiting the valve body from generating circumferential rotation; when the knob adjusting device is applied to a water outlet device, the application can avoid the situation that the constant temperature valve is integrally rotated due to excessive rotation force of the water mixing valve, and the water temperature is not accurately adjusted.
