Referring to fig. 2, 4 and 5, the valve body 21 is a main part of the water outlet device body, and is surrounded by the housing to form a circular tubular chamber, and the two ends of the chamber are opened to form a water passing cavity 212. A third water outlet 251 for water outlet is formed on the shell at a position close to the first end opening of the water passing cavity 212; a water inlet channel 211 for water inlet is arranged on the shell at the middle position of the water passing cavity 212; at a position close to the opening of the second end of the water passing cavity 212, the shell extends to two sides along the radial direction of the water passing cavity 212 to form two wing plates, and the two wing plates are respectively provided with an electromagnetic valve installation notch for installing and fixing an electromagnetic valve; meanwhile, two water passing grooves are arranged on the two wing plates, and both the two water passing grooves are communicated with the second end opening of the water passing cavity 212.

The first sealing ring 26 is installed on the end surface of the water passing hole 214 facing the third water outlet 251 and is fitted to the wall of the water passing cavity 212, and the first sealing ring 26 is a V-shaped sealing ring, and the opening direction of the first sealing ring faces the position of the water inlet channel 211.

Meanwhile, a flange is arranged in the water passing cavity 212, the flange protrudes from the inner wall of the water passing cavity 212 towards the water passing cavity 212, the flange may be a single block-shaped structure or an annular structure formed along the circumferential direction, and the flange has a wall surface perpendicular to the axial direction of the water passing cavity 212 and away from the position of the water inlet channel 211, and the wall surface forms a limiting wall 2121.

The valve cover 22 is fixedly connected with the valve body 21 into a whole in a screwing, clamping or welding mode and the like, and covers two wing plates on the valve body 21 to form a chamber for water passing. Referring to fig. 5, the valve cover 22 and the valve body 21 cooperate to form a first water outlet channel 223 and a second water outlet channel 224 corresponding to the two wing plates, the two water outlet channels are both communicated with the water passing cavity 212 through the water passing groove, and correspond to the two water outlet channels, the valve cover 22 is provided with a first water outlet 221 and a second water outlet 222, the first water outlet channel 223 is communicated with the first water outlet 221, and the second water outlet channel 224 is communicated with the second water outlet 222.

The fixing sleeve 24 is inserted into the water passing cavity 212 from the first end of the water passing cavity 212 and is tightly fixed by elastic deformation, and at the same time, abuts against the first sealing ring 26, so that the first sealing ring 26 can be fixed in the water passing cavity 212.

The rear cover 25 is inserted into the water passing cavity 212 from the first end of the water passing cavity 212 and abuts against the fixing sleeve 24, and is fixed by friction fit with the cavity wall of the water passing cavity 212, and can rotate relative to the valve body 21. When the rear cover 25 is mounted to the valve body 21, it cooperates with a portion between the water through hole 214 and the first end of the valve body 21 to form a third water outlet passage 213, and the third water outlet passage 213 communicates with the third water outlet 251. Meanwhile, a water passing notch is formed in the side wall of the rear cover 25 extending into the water passing cavity 212, the water passing notch can be rotated to a position corresponding to the third water outlet 251 by the rear cover 25, and the third water outlet 251 is opened; when the water gap is then rotated by the cover 25 to the position where the third water outlets 251 are staggered, the third water outlets 251 are closed.

The first electromagnetic valve 27 and the second electromagnetic valve 28 are used as electrical appliances in the present embodiment, and are respectively installed in two electromagnetic valve installation notches on the valve body 21, and a piston on the electromagnetic valve can block the communication between the water passing groove on the wing plate and the first water outlet 221 and the second water outlet 222, so that the opening and closing of the first water outlet passage 223 and the second water outlet passage 224 can be controlled.

The main body of the water sealing member 23 is a rod-shaped member, a pressure bearing block 231 and a blocking block 232 are respectively arranged at two ends of the rod-shaped member in a protruding manner along the radial direction, and the diameter of the pressure bearing block 231 is larger than that of the blocking block 232. A sealing ring groove is circumferentially arranged on the outer edge of the bearing block 231, the sealing ring groove is used for installing a second sealing ring 234, the second sealing ring 234 is a V-shaped sealing ring, so that a one-way sealing ring is formed, and the opening of the one-way sealing ring deviates from the position of the water inlet channel 211. A plurality of projections 233 are further circumferentially arranged on the outer edge of the bearing block 231, and the projections 233 extend in the radial direction of the rod-shaped main body of the water sealing member 23.

The water seal 23 is installed in the water passing cavity 212 and the block piece 232 passes through the water passing hole 214. The outer diameter of the blocking block 232 is approximately matched with the inner diameter of the water through hole 214, when the blocking block 232 is just located in the range of the water through hole 214, the outer edge wall surface of the blocking block 232 can be matched with the first sealing ring 26 to block the water through hole 214, and the communication between the water through cavity 212 and the third water outlet channel 213 is cut off. The convex block 233 on the bearing block 231 is just abutted against the cavity wall of the water passing cavity 212 parallel to the first direction, which enables the water sealing member 23 to be limited by the cavity wall of the water passing cavity 212 in the radial direction, thereby limiting the moving direction of the water sealing member 23, meanwhile, due to the arrangement of the convex block 233, a gap is formed between the outer edge of the bearing block 231 and the cavity wall of the water passing cavity 212, and a water passing channel formed by the gap can enable water flow to pass through. The second sealing ring 234 sleeved on the bearing block 231 abuts against the wall of the water passing cavity 212 parallel to the first direction, and the second sealing ring 234 is opened away from the water inlet channel 211, so that only water is allowed to flow from the water inlet channel 211 to the first water outlet channel 223 and the second water outlet channel 224, and water is prevented from flowing from the first water outlet channel 223 and the second water outlet channel 224 to the water inlet channel 211.

In addition, the outer diameter of the pressure-bearing block 231 is larger than the inner diameter of the water passing cavity 212 at the position of the limiting wall 2121, so that when the water sealing member 23 moves to the position of the limiting wall 2121, the pressure-bearing block 231 abuts against the limiting wall 2121, thereby preventing the water sealing member 23 from moving further, and the pressure-bearing block 231 is always located between the water inlet passage 211 and the first and second water outlet passages 223, 224. Meanwhile, since the pressure-bearing area of the pressure-bearing block 231 toward the water inlet passage 211 is greater than the pressure-bearing area of the blocking block 232 toward the water inlet passage 211, when one of the first water outlet passage 223 or the second water outlet passage 224 is opened to form water, and the third water outlet passage 213 also forms water, the water blocking member 23 moves toward the direction of the first water outlet passage 223 and the second water outlet passage 224, thereby blocking the water passing hole 214 through the blocking block 232. In addition, owing to be provided with second sealing washer 234, when first exhalant canal 223 and second exhalant canal 224 all closed, the atress that one side that pressure-bearing piece 231 deviates from inhalant canal 211 can be greater than its one side towards inhalant canal 211, in addition the power that blocking piece 232 itself received, the rivers can promote water sealing member 23 towards the position of third delivery port 251, until pressure-bearing piece 231 supports spacing wall 2121, thereby make blocking piece 232 leave the position of water hole 214, reopen the intercommunication of third exhalant canal 213 and water cavity 212. It should be noted that in other embodiments, the difference between the pressure receiving areas on the two sides of the pressure receiving block 231 is smaller than the pressure receiving area of the blocking block 232 on the side facing the water inlet channel 211, so that the water sealing member 23 can open the water through hole 214 when the first water outlet channel 223 and the second water outlet channel 224 are closed. For example, even if the pressure-bearing area of the pressure-bearing block 231 on the side facing the water inlet passage 211 is larger than the pressure-bearing area of the pressure-bearing block 231 on the side facing away from the water inlet passage 211, as long as the area difference between the two is smaller than the pressure-bearing area of the blocking block 232 on the side facing the water inlet passage 211, when the first water outlet passage 223 and the second water outlet passage 224 are closed, the force exerted by the water flow on the blocking block 232 is larger than the force exerted by the water flow on the pressure-bearing block 231, and the water blocking member 23 opens the water through hole 214.

Referring to fig. 3 and 9, the power supply module 30 is mainly composed of a slider 31, a third seal ring 312, a magnetic member 32, an elastic member 33, a hall element 34, a circuit board 341, a circuit case 342, and a battery 35.

The sliding piece 31 is installed in the sliding cavity 41, and the outer edge of the water baffle 311 on the sliding piece abuts against the cavity wall of the sliding cavity 41, so that the sliding piece 31 can slide along the extending direction of the sliding cavity 41; meanwhile, the third sealing ring 312 is also abutted to the wall of the sliding cavity 41, and the opening direction of the third sealing ring 312 faces to the position of the water inlet hole, so as to prevent water from flowing through the water baffle 311 from the water inlet hole of the sliding cavity 41 to the other side of the water baffle 311. The stem of the slider 31 passes through a through hole in the bottom wall of the slide chamber 41 and protrudes outside the slide chamber 41, and the magnetic member 32 fixed thereto is also located outside the slide chamber 41. The other end of the elastic member 33 abuts against the bottom wall of the slide chamber 41. When the ball head assembly 12 is filled with water, water flows into the sliding cavity 41 through the water inlet hole, and pushes the sliding piece 31 to slide, so that the magnetic piece 32 is close to the Hall element 34, and the switching state of the Hall element 34 is switched; when the ball head assembly 12 stops feeding water, under the action of the elastic member 33, the sliding member 31 is reset, and the magnetic member 32 is moved away from the hall element 34, so that the hall element 34 returns to the initial state. Through the reciprocating sliding of the sliding member 31, the hall element 34 starts the circuit board 341 when the shower head enters water, and closes the circuit board 341 when the shower head closes the water inlet, thereby reducing the loss of the battery 35.
