[0028] Embodiment 1

[0029] From Figure 1 It can be seen that the multifunctional shower arm of the present embodiment 1 has a tubular connecting body 1, at least one water inlet pipe 13 for water inlet is arranged on the connecting body 1, and a plurality of connecting pipe bodies 14 are arranged in parallel communication on the connecting body 1. The connecting pipe body 14 is provided with a water outlet 16 at the lower end of the peripheral portion. The water inlet pipe 13 is used for water inlet, and the water enters the pipe cavity of the connecting pipe body 14 and then is output from the water outlet 16.

[0030] The connecting body 1 is provided with an elongated arm in communication with the connecting body 1. The elongated arm has a support arm 8, an elongated pipe body 17 in communication with the support arm 8, and a water outlet end 18 arranged at the end of the elongated pipe body 17. The support arm 8 is provided with a communication port in communication with the front end port of the elongated pipe body 17. In this way, the support arm 8, the elongated pipe body 17, and the water outlet end 18 form a communication elongated arm. The water output from the water outlet 16 enters the elongated pipe body 17 through the communication port and is output at the water outlet end 18.

[0031] The lengthened arm is connected to the connecting body 1 through the support arm 8 rotating, so that the pipe of the lengthened pipe body 17 communicates with the pipe of the connecting body 1 through the communicating port and the water outlet 16. In this way, water enters from the water inlet pipe 13, enters the lengthened pipe body 17 through the pipe of the connecting body 1 respectively, and then flows out from the water outlet end 18 of the lengthened pipe body 17. The support arm 8 is sleeved on the pipe of the connecting body 1, so that the lengthened arm can be adjusted by rotating, so as to adjust the water outlet distance between the water outlet ends 18 of the two lengthened arms.

[0032] The water inlet pipe 13 is connected with the water level screw 4 at the water inlet end, provided with the flat rubber ring 5 outside the water level screw 4, the O-shaped ring 3 inside the water level screw 4, and the movable nut 13 sleeved on the water level screw. Such design makes the movable nut have better connection, and the flat rubber ring 5 and the O-shaped ring 3 have better sealing.

[0033] The support arm 8 is sleeved on the connecting pipe 14, and the connecting part of the support arm 8 and the connecting pipe 14 is provided with the wear-resistant gasket 6 and the O-shaped ring 7, and the port of the connecting pipe 14 is provided with the fastening joint 9. The two wear-resistant gaskets 6 are arranged at the two ports of the support arm 8, which increases the wear resistance when the support arm 8 rotates with the connecting pipe 14, and increases the service life. Similarly, the O-shaped ring 7 is arranged at the two ports of the support arm 8 and located inside the wear-resistant gasket 6, which increases the sealing of the connection between the support arm 8 and the connecting pipe 14. The fastening joint 9 seals the port of the support arm 8 and the connecting pipe 14.

[0034] The two end ports of the connecting body 1 are provided with the cover 15, so that the two ends of the connecting body 1 do not have water, and water enters the lengthened arm through the connecting pipe.

[0037] In this example, one end of the connecting body 1 is closed, and the single-function control valve is not used, water directly enters the lengthened arm from the connecting body 1, and then flows out from the water outlet end of the lengthened arm, and the other end controls the water inlet or no water inlet of the lengthened arm at the end through the single-function valve core 12.

[0038] Example three:

[0039] As shown in Figure 3 and 6, 7; unlike the embodiment 1 and embodiment 2, the two end ports of the connecting body 1 of this embodiment 3 are not sealed, but are screw ports, and a single-function control valve is arranged at the screw ports, which controls the water inflow or no water inflow of the open-end lengthened arm, and the single-function control valve comprises a single-function valve core 12 and a hand wheel 11 connected to the single-function valve core 12.

[0040] This embodiment is not sealed at both ends, and the water inflow or no water inflow of the two lengthened arms is controlled by the single-function valve core 12 arranged respectively.

[0041] Embodiment four:

[0042] As shown in Figure 4 and 5 , unlike the embodiment 1, embodiment 2 and embodiment 3, the two end ports of the connecting body 1 of this embodiment 4 are provided with a cover 15, i.e. the two end ports are sealed, and a control pipe is arranged at the opposite position of the water inflow pipe 13 to control the water distribution of the water inflow pipe 19; the control pipe 19 is connected with the pipe cavity of the connecting body 1, and a multi-function control valve is arranged here, which comprises a multi-function valve core 43, a gland 44 arranged at the outer end of the multi-function valve core 43 and a hand wheel 11.

[0043] In this embodiment, the water outflow of the two lengthened arms is controlled by the multi-function valve core 43 at the control pipe, and the water outflow or no water outflow of the two lengthened arms at both ends is controlled.

[0044] The structure of the single-function valve core 12 used in the above-mentioned embodiments 2-3 is as follows:

[0045] As shown in Figure 6 and 7 , the multi-function valve core 43 comprises an upper 90° ceramic sheet 37 and a lower 90° ceramic sheet 38; a sealing ring 39, a copper bottom cover 41 and a bottom silica gel 40 are arranged below the lower 90° ceramic sheet 38; a copper valve shell 33 and a copper rod 36 embedded in the inner cavity of the copper valve shell 33 are arranged above the upper 90° ceramic sheet 37, a friction sheet 35 is arranged at the contact position between the copper rod 36 and the bottom end of the copper valve shell 33, a sealing ring 34 is arranged at the contact position between the copper rod 36 and the middle peripheral part of the copper valve shell 33, and a circlip 32 is arranged at the contact position between the copper rod 36 and the top end of the copper valve shell 33; a sealing ring 42 is sleeved on the copper valve shell 33.
