As shown in fig. 1 and 2, the first inlet pipe 51 on the left side of the waterway switch valve 10 may be a hot inlet channel, the second inlet pipe 52 on the right side may be a cold inlet channel, the first outlet pipe 53 on the upper side may be an outlet channel of a shower head, and the second outlet pipe 54 on the lower side may be an outlet channel of a bathtub. As shown in fig. 15, when the water path switching valve 410 of the lower water outlet assembly 40 is opened, as shown in fig. 12, when the first water inlet hole 1310 and the second water inlet hole 1320 of the main control valve core 140 in the control installation groove 133 are opened, water flows into the cavity between the main control valve core 140 and the installation groove 133 through the first water inlet hole 1310 and the second water inlet hole 1320; as shown in fig. 13, the water flows from the cavity to the guide member 120 through the water outlet hole 134 at the bottom of the mounting groove 133, and flows from the first end 1221 of the second conduit 122 in the guide member 120 to the second water outlet 114; due to the venturi effect generated by the flow guide member 120, when the waterway connected to the second water outlet 114 is opened, a negative pressure is generated at the second end 1212 of the first conduit 121, that is, the second end 1212 of the first conduit 121 is at a negative pressure relative to the first end, so that the water flow is prevented from flowing backwards from the second end 1212 to the first end of the first conduit 121; at this time, as shown in fig. 14, the shower is in a low water state. As shown in fig. 17, when the water passage switching valve 410 of the water outlet assembly is closed, the water flows to the upper water outlet assembly 30 by the reverse flow; at this time, as shown in fig. 16, the shower is in the water up state. The switching of the water outlet direction of the shower can be realized by controlling the water path switch valve 410 of the lower water outlet assembly 40.
Wherein, the control end of the main control valve core 140 is provided with a control handle 20, for example, the first water inlet hole 1310 and the second water inlet hole 1320 at the bottom of the mounting groove 133 can be opened by pulling the control handle 20, so that the water in the first water inlet hole 1310 and the second water inlet hole 1320 flows to the water outlet hole 134; the outlet water temperature can be controlled by rotating the control handle 20 left and right; when the inlet water of the first inlet pipe 51 on the left side of the control handle 20 is hot water and the inlet water of the second inlet pipe 52 on the right side is cold water, the opening of the first inlet hole 1310 is enlarged and the opening of the second inlet hole 1320 is reduced when the control handle 20 is rotated to the left side, so that the outlet water temperature is increased; if the control handle 20 is rotated to the left extreme position, the opening of the first inlet hole 1310 is fully opened, and the second inlet hole 1320 is fully closed, i.e. the outlet pipe is flowing hot water from the first pipe. Conversely, by rotating the control handle 20 to the right, the opening of the second inlet hole 1320 becomes larger, and the opening of the first inlet hole 1310 becomes smaller, thereby lowering the outlet water temperature; if the control handle 20 is rotated to the right limit position, the opening of the second inlet hole 1320 is fully opened, and the first inlet hole 1310 is fully closed, i.e. the outlet pipe is the cold water of the second pipe.
In an embodiment of the present disclosure, as shown in fig. 15 and 17, the water path switching valve 410 of the lower water outlet assembly 40 includes a lifting rod and a blocking cover, and the blocking cover is fixedly disposed on the lifting rod and drives the blocking cover to move synchronously along with the lifting rod moving up and down. As shown in fig. 15, when the lifting rod is located at the pressing position, the plugging cover moves downwards to open the pipeline; as shown in fig. 17, when the lifting rod is located at the lifting position, the blocking cover moves upwards to block the pipeline, so that the water outlet is opened and closed. Of course, other switch valves, such as a rotary switch valve, may be further provided, which is not limited in the disclosure, and all switch valves capable of realizing opening and closing of the water path belong to the protection scope of the disclosure.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.
