[embodiment]

Describe the concrete structure of the utility model current-limiting type water tap in detail below in conjunction with accompanying drawing.

Please join Fig. 1 and Fig. 2, the utility model current-limiting type water tap 10 comprise accommodation section 11, with accommodation section 11 cooperate in order to drive roller 16 (please join the rotation of Fig. 3-Fig. 5) operation unit 12, is connected the intake pipe 13 of water source and accommodation section 11 and the outlet pipe 14 of connection accommodation section 11.

Operation unit 12 can rotate in the plane at Fig. 2 place (paper), and accommodation section 11 is provided with rotating range and the sense of rotation of two limiting stoppers 15 in order to restriction operation portion 12.

Please join Fig. 3, accommodate roller 16 in the accommodation section 11, among Fig. 3 to Fig. 5, slit between roller 16 and the accommodation section 11 has been done to exaggerate, so that explanation position relation between the two, in fact between roller 16 and the accommodation section 11 for water-stop cooperates, assurance is not leaked by water or other liquid wherein.On the madial wall of accommodation section 11 (side that promptly cooperates) three recesses are set, are defined as first recess 111, second recess 112 and the 3rd recess 113, respectively in order to limit three kinds of states of the utility model water tap with roller.

Roller 16 is spherical, and its part is connected on the operation unit 12, and by rotary manipulation portion 12, roller 16 can rotate in accommodation section 11.Roller 16 is provided with first passage 161 and the second channel 162 that runs through self, and the internal diameter of first passage 161 is greater than the internal diameter of second channel 162.Be provided with breach 163 on the roller 16 in addition, in be provided with spring 164, spring 164 tops are connected with

positioning body

165, and 164 one-tenth compressive states of spring make positioning body 165 withstand on the madial wall of accommodation section 11.

Fig. 3 is the closed condition schematic representation of the utility model current-limiting type water tap 10.Under this state, positioning body 165 is withstood in first recess 111 by spring 164, and first passage 161 and second channel 162 are neither to communicate with outlet pipe 14 with intake pipe 13.

Rotary manipulation portion 12, make roller 16 turn clockwise in the position of Fig. 3, forward state shown in Figure 4 to, under this state, positioning body 165 is withstood in second recess 112, and second channel 162 then is communicated with intake pipe 13 and outlet pipe 14, at this moment, intake pipe 13, second channel 162, outlet pipe 14 constitute flow path, and the water flow that meets second channel 162 internal diameters flows out, and is small water flow.The two ends of first passage 161 are because can't be flowed out current by the sealing of the madial wall of accommodation section 11.
