One end of the rod body 114 is coaxially connected with the convex portion 1131 of the end cap 113 to form an integral structure. The rod 114 penetrates into the cavity 1111 of the core 111, and the other end of the rod 114 is screwed with the core 111.

The end cap 113 is fixedly connected to the core 111 via the rod 114. After the rod 114 is inserted into the core 111, the end cap 113 is rotated to screw the rod 114 to the core 111, and the end cap 113 also seals the opening 1112.

The end cap 113 can be quickly assembled to the opening 1112 of the core body 111 through the rod body 114, and the rod body 114, the end cap 113 and the core body 111 are coaxial, so that when the valve core 11 rotates, the rod body 114 can also play a role in stabilizing the rotating axis.

In yet another embodiment, as shown in fig. 5, the valve body 10 further includes an inlet/outlet 106 for the valve element 11 to enter and exit. The inlet/outlet 106 is located at an end of the valve body 10 to facilitate the inlet/outlet of the valve body 10 with respect to the valve body 11. As shown in fig. 10, the direction valve 1 further includes a valve cover 15 that covers the inlet/outlet 106. After the valve core 11 is installed in the valve body 10, the valve cover 15 can be covered on the inlet and outlet 106, and the valve cover 15 can be fixedly connected with the valve body 10 through screws. The valve cover 15 can play a role in sealing, and can also seal the valve core 11 in the valve body 10 to play a role in protecting the valve core 11.

In one embodiment, as shown in fig. 10, the valve body 10 is provided with a slot 107. The number of the insertion grooves 107 is two, and the two insertion grooves 107 are arranged in parallel along the axial direction of the valve body 10. Two sides of the water outlet 103 are respectively provided with a slot 107.

As shown in fig. 11, the nozzle holder 3 includes a holder body 30 and a guide post 32 fixedly disposed on a bottom surface of the holder body 30. As shown in fig. 12, there are two guide posts 32, and the two guide posts 32 are arranged in parallel and can be correspondingly inserted into the two slots 107. The guide posts 32 are disposed coplanar with the bottom surface of the base 30. The nozzle holder 3 is fixed to the valve body 10 by inserting the guide post 32 into the insertion groove 107.

As shown in fig. 13, the selector valve 1 and the nozzle holder 3 are fixedly assembled, and the assembly of the head is completed. As shown in fig. 2, the motor 41 is placed in the lower cover 442, and the upper cover 441 is covered on the motor 41 and engaged with the lower cover 442. Then, as shown in fig. 3, the connection frame 43 is fixedly connected to the valve body 10 and the lower cover 442, respectively. As shown in fig. 1, the transmission shaft 42 is inserted into the connecting frame 43, one end of the transmission shaft is inserted into the groove 1121 of the transmission body 112 to be in transmission connection with the valve core 11, and the other end of the transmission shaft is in transmission connection with the output shaft of the motor 41.
