An elastic member 34 is sleeved on the sliding valve core 12, and the elastic member 34 can be a spring, and the two ends of the spring act respectively on the pressure-bearing member 33 and the wall surface of the valve cavity.

A limiting protrusion 35 is provided on the cavity wall of the valve cavity.

The utility model also provides a shower, comprising a shower housing 3, a water power generator 4, a controller 5, a face cover 6 and a water outlet body 7, the water power generator 4 is communicated with the water inlet 13, and the water outlet body 7 is connected with the face cover 6. A plurality of shower outlet water channels are formed together, the shower housing 3 and the face cover 6 cooperate to form a chamber, and the shower water channel switching valve and the controller 5 are both fixed in the chamber.

When assembling, firstly connect the first water passage 15 and the second water passage 25 of the hydraulic drive valve assembly 1 and the solenoid valve assembly 2 through pipes or by connecting the two, so that the water flow can pass through the first water passage 15 and the second water passage. The second water passage 25 flows into the water passage 23 of the second valve body 21; after that, the water outlet body 7 is fixed to the face cover 6 according to the preset position to form a plurality of shower outlet water passages, and then the controller 5 is clamped to the outlet. On one side of the water body 7, the plurality of second water outlets 25 of the solenoid valve assembly 2 and the first water outlet 14 of the hydraulic drive valve assembly 1 are respectively connected to the corresponding shower outlet water channels, and the connected water The pressure-driven valve assembly 1 and the solenoid valve assembly 2 are fixed on the water outlet body 7; then the water outlet end of the hydraulic generator 4 is connected with the water inlet channel 13 of the water pressure-driven valve assembly 1, and finally the shower project 3 is connected to the face cover 6. Butt joint, so that the water outlet 7, the controller 5, the hydraulic generator 4 and the waterway switching valve are all fixed in the internal chamber of the shower head.

In specific use, the shower provided by the present invention is communicated with the water inlet valve. When the water inlet valve is opened, the water flows into the shower head through the top inlet of the shower casing 3, and firstly flows into the hydroelectric generator 4. The hydroelectric generator 4 The water outlet of the valve is connected to the water inlet 13 of the hydraulically driven valve assembly 1 , and the water flow enters the valve cavity of the first valve body 11 at this time.

When the hydraulic generator 4 is not running, the controller 5 does not have enough power to drive the solenoid valve 22 to open, and the solenoid valve 22 also does not have enough power to operate, so the solenoid valve 22 is closed at this time, although the hydraulic drive valve assembly 1 and The solenoid valve assemblies 2 are communicated with each other through the first water passage 15 and the second water passage 24, and the water flow cannot pass through the second water outlet 25 of the solenoid valve assembly 2. At this time, in the hydraulically driven valve assembly 1, due to Due to the action of the blocking member 32 , the valve cavity is filled with water and cannot flow to the first water outlet 14 , which causes the water pressure on both sides of the water passage hole 31 to be unbalanced. The action of water pressure drives the sliding valve core 12 to slide, and causes the blocking member 32 to pass through the water hole 31, so that the water inlet 13 and the first water outlet 14 are connected smoothly, and the water flows through the first water outlet 14 and then passes through the corresponding flower. The sprinkling water channel flows out of the shower, thereby forming a smooth water channel inside the shower. At this time, the hydroelectric generator 4 can run smoothly.

The limiting protrusion 35 provided on the cavity wall of the valve cavity of the first valve body 11 can abut against the pressure-bearing member 33 when the pressure-bearing member 33 slides to a specific position with the sliding valve core 12, so as to prevent the sliding valve core 12 from facing excessively. If the sliding distance in the direction of the water hole 31 is too large, the pressure bearing member 33 blocks the water passage hole 31 .

When the hydraulic generator 4 is running, the controller 5 and the solenoid valve 22 have enough power to control and operate, so that any solenoid valve 22 can be opened as required, so that the second water outlet 25 corresponding to the solenoid valve 22 can be opened. out of water. When any second water outlet 25 is connected, the blocking member 32 blocks the water passage hole 31. The specific process is as follows: the blocking member 31 is originally in a state away from the water passage hole 31, and when the water flows from the water inlet passage 13 into the first valve body After the valve cavity of 11, it then flows into the water passage 23 of the second valve body 21 through the first water passage 15 and the second water passage 24. At this time, a second water outlet 25 is in an open state, and the water flows smoothly from the second water outlet. When the water outlet 25 flows out, since the pressure-receiving area of the pressure-bearing member 33 is larger than the pressure-bearing area of the blocking member 32, the water pressure formed by the water flow impacting the pressure-bearing member 33 is greater than the water pressure formed by the water flow impacting the sealing member 32, so that the two A water pressure difference is formed between the two, thereby driving the sliding valve core 12 to slide toward the first water passage 15 , driving the blocking member 32 to approach the water passage hole 31 and finally blocking the water passage hole 31 . At this time, the communication between the water inlet channel 13 and the first water outlet channel 14 is cut off, and the switching of the shower outlet water channel is controlled by the solenoid valve 22 .

The utility model provides a shower water channel switching valve and a shower. By arranging a water channel switching valve inside the shower, and connecting the hydraulic generator with the water inlet channel of the water channel switching valve, when the electromagnetic valve is not energized, all the second When the water outlet is in the closed state, the sliding valve core in the water channel switching valve is driven by water pressure to open the first water outlet, thereby forming a smooth water channel, so that the hydroelectric generator can be driven by the water flow to generate electricity, so that the solenoid valve can be opened, solving the problem. In the case of no external power supply and the solenoid valve is closed, the connected hydraulic generator cannot run to generate electricity. At the same time, the water circuit switching valve is divided into a hydraulic drive valve assembly and a solenoid valve assembly, and the water passages of the two are passed through the pipeline. Alternatively, it can be connected by means of fixed connection, which further increases the water outlet flow and improves the water outlet effect. At the same time, the separately formed hydraulically driven valve assembly and solenoid valve assembly improve the yield of the waterway switching valve and reduce the maintenance cost.

The descriptions of the above specification and embodiments are used to explain the protection scope of the present invention, but do not constitute a limitation to the protection scope of the present invention. Through the enlightenment of the present invention or the above-mentioned embodiments, those of ordinary skill in the art can obtain an understanding of the present invention through logical analysis, reasoning or limited experiments in combination with common knowledge, common technical knowledge in the field and/or prior art.
