Because the first pressure-bearing area is larger than the second pressure-bearing area, when liquid flows in the water channel, the first central bolt keeps downward state along the axis under the action of hydraulic pressure after the external force is removed, so that the corresponding flow channel is communicated with the main flow channel; when the liquid is cut off, the hydraulic pressure disappears, the first central bolt maintains the upward state along the axis under the action of the first elastic piece, and the main flow channel is communicated with the corresponding outlet end again.

8-9, the control valve assembly controls the pressure of the 2 nd flow passage and the 3 rd flow passage by controlling the size of the liquid passing passage of the main flow passage; the control valve assembly comprises a second elastic piece and a second central bolt assembly, the second central bolt assembly comprises a second outer ring and a second central bolt positioned in the second outer ring, the second outer ring and the water channel assembly are relatively fixed, the second central bolt can move up and down in the second outer ring along an axis under the interaction of external force and the second elastic piece, the second central bolt assembly comprises a third pressure bearing surface and a fourth pressure bearing surface, and the axial projection areas of the third pressure bearing surface and the fourth pressure bearing surface are equal. Because the third pressure bearing face and the fourth pressure bearing face are equal in area, even when liquid flows in the flow channel, after the external force is removed, the second central bolt can always maintain the upward state along the axis under the action of the second elastic piece, so that the inlet end and the main flow channel are always kept in a communicated state.

With reference to fig. 10-11 of the specification, a first key cap is disposed above the control valve assembly, and a second key cap and a third key cap are disposed above the switching valve assembly, respectively.
