Waterway switching valve

A waterway switching valve, comprising:

• a valve body,
• a switching operating member, and
• a switching member, wherein:
• the valve body comprises a water inlet, a first water outlet, and a second water outlet,
• the switching operating member is operatively connected to the switching member,
• the switching member is sequentially disposed with a first sealing member, a first pressure relief member, a second pressure relief member, and a second sealing member along a moving direction of the switching member,
• a first pressure generating cavity and a second pressure generating cavity are disposed in the valve body along the moving direction of the switching member,
• a blocking member is disposed in the valve body between the first pressure generating cavity and the second pressure generating cavity,
• the blocking member comprises a first flow passage and a second flow passage isolated from the first flow passage,
• the first flow passage and the second flow passage are respectively in communication with the first water outlet and the second water outlet,
• the first pressure generating cavity comprises a first opening,
• the second pressure generating cavity comprises a second opening,
• the switching member passes through the first opening and the second opening,
• when the switching operating member drives the switching member to move to enable the first sealing member to correspond to the first opening of the first pressure generating cavity:
• the first pressure generating cavity is in a pressure suppression state,
• water pressure drives the first pressure generating cavity to abut and seal an upper end surface of the blocking member, and
• the first water outlet is isolated from the water inlet, and
• when the switching operating member drives the switching member to move to enable the first pressure relief member to correspond to the first opening of the first pressure generating cavity:
• the first pressure generating cavity is in a pressure relief state,
• the first pressure generating cavity is separated from the upper end surface of the blocking member, and
• the first water outlet is in communication with the water inlet.
