SINGLE COLD FLUSHING COVER PLATE KNOB AND SINGLE COLD FLUSHING DEVICE

摘要

A single cold flushing cover plate knob (100) and a single cold flushing device. The knob is connected with a single cold flushing control valve provided with a rotary part which rotates among different angular positions so as to enable the control valve to switch between an initial state and a water outlet state. The knob (100) comprises a connecting portion (110) and a handle (120), the connecting portion (110) being connected with the rotary part in a synchronously rotating mode, the handle (120) being fixedly connected with the connecting portion and the tail end of the handle stretches out of the connecting portion (110), and additionally, the handle (120) stretching upwards relative to the connecting portion when the rotary part is located at a position corresponding to the initial state of the control valve. The knob (100) has the following advantages: a, when the control valve is in the initial state, the handle (120) stretches upwards, the upper end portion of the handle (120) is higher than a ceramic surface, so that a user can directly grasp the handle (120) without reaching out the fingers under the ceramic surface to grasp the knob (100), the fingers can be prevented from touching ceramics and a seat ring (400), and the knob is convenient to use; b, the moment of the handle (120) is long so as to reduce operating force; and c, the knob can be used on a thin cover plate.
