Embodiment:
As shown in Figure 1, a kind of quick switching combining shower nozzle, mainly fixedly ejectisome 3 and a rotary-jet body 10 are formed by one.Rotary-jet body 10 is set in fixedly and makes axial location with holding screw 12 behind the ejectisome 3, and by the footpath of selecting suitable fixedly ejectisome 3, rotary-jet body 10 and holding screw 12 corresponding sites, axial fit tolerance, rotary-jet body 10 can easily be rotated with respect to fixing ejectisome 3, and rotary-jet body 10 relative fixed ejectisomes 3 have the mating surface that circumference is rotationally connected.The loosening problem of holding screw 12 when the threaded portion was coated with and rotates to avoid rotary-jet body 10 with soft solidity binding agent when holding screw 12 was packed fixing ejectisome 3 into.Fixedly ejectisome 3 inside are provided with the pressure fluid transfer passage, and the import of this passage is connected part 1 by spraying system and is connected with the pressure fluid carrier pipe, and the outlet of this passage is positioned on the described mating surface, and the eccentric setting of center of rotation of rotary-jet body 10 relatively.Channel exit is established a hole seat, be located in a piston 7 in the seat of hole, the axial centre of piston 7 is provided with through hole as the liquid outlet runner, seal by O RunddichtringO 6 between the outer rim of piston 7 and the hole seat, the rear end face of piston 7 is provided with piston spring 4, seals by annular end sealing ring 8 between the mating surface of front end face and rotary-jet body 10.Under the off working state, be pressed against all the time on the rotary-jet body 10 corresponding planes at the movable sealing face of annular end sealing ring 8 under the effect of piston spring 4.When rotary-jet body 10 rotated to a certain nozzle operation position and input pressure liquid, O RunddichtringO 6 and annular end sealing ring 8 had been blocked the leakage path of pressure fluid, caused it to flow out by the nozzle spray orifice and formed jet.In addition, under the effect of pressure fluid, piston 7 has additionally increased an axial force to the right, thereby the sealing property of 10 of annular end sealing ring 8 and rotary-jet bodies is further improved, under the prerequisite of annular end sealing ring 8 performances permission, high more its sealing property of the pressure of liquid is good more.
As shown in Figure 2, the outlet flow position of corresponding piston 7, homogeneous phase is every the nozzle 11 that six various traits are set on the circumferencial direction of rotary-jet body 10.Rotary-jet body 10 is provided with step-like nozzle installing hole 17 (see figure 1)s, and its aperture combines with nozzle 11 corresponding sites with interference fit, thereby solves the leakage problem of pressure fluid herein.Step surface and nozzle 11 step surfaces are near, the axial force that produces under the pressure fluid effect with balance nozzle 11.The quantity of nozzle installing hole 17 shown in Figure 2 is 6, and its quantity can suitably increase and decrease according to actual needs.
As shown in Figure 1 and Figure 2, rotate orientation problem in the handoff procedures, on the circumference rotation direction, be provided with elastic bumps switching location structure between the mating surface of rotary-jet body 10 and fixing ejectisome 3 in order to solve nozzle 11.Described elastic bumps switches location structure and is made of retainer spring 13 and locking ball 14, retainer spring 13 and locking ball 14 are located in the locating hole on the fixing ejectisome 3, and rotary-jet body 10 corresponding locking balls 14 are separated by in a circumferential direction to be provided with to rotate and are switched positioning pit 15.Rotate rotatable ejectisome 10 when need switching nozzle 11, when rotary-jet body 10 turned to next nozzle 11, locking ball 14 entered in the corresponding switching positioning pit 15, makes this locational nozzle 11 be accurately positioned in the through hole front position of piston.
To switch the big problem of nozzle resistance under the high pressure conditions in order solving, between two adjacent nozzles 11 on rotary-jet body 10 mating surfaces, to be provided with and to switch pressure relief groove 16.The quantity of switching pressure relief groove 16 is identical with the quantity of described nozzle 11, and angle is corresponding, promptly when rotate rotatable ejectisome 10 with nozzle 11 by one in another handoff procedure, be provided with one and switch pressure relief groove 16, reach by this switching pressure relief groove 16 and reduce the purpose of switching resistance.If there is not this groove, when rotary-jet body 10 rotates to two nozzle installing holes, 17 mid-plane positions as shown in Figure 2, and during the careless input pressure liquid of operator, the frictional resistance of 12 of annular end sealing ring 8 and rotary-jet body 10 and rotary-jet body 10 and holding screws is assembled and is increased and cause rotary-jet body 10 rotation difficulties under the effect of pressure fluid, thereby is difficult to switch nozzle or damages annular end sealing ring 8.After switching pressure relief groove 16 is set on the rotary-jet body 10, if when running into above-mentioned situation again, pressure fluid can be through switching the slit release of pressure relief groove 16 and rotary- jet body 10 and 12 of holding screws, thereby solved nozzle switching difficulty or the annular end sealing ring 8 damage problems that above-mentioned maloperation causes.
As shown in Figure 1, in addition, the fixing big O RunddichtringO 9 that is provided with of ejectisome 3 and rotary-jet body 10 radial fit portions, backward leakage path when having blocked the pressure fluid release, outward appearance cleaning when making shower nozzle switch operation.Fixedly stud with respectively on ejectisome 3 and the rotary-jet body 10 fixedly mould the cover 2 and rotation mould the cover 5, rotation mould cover 5 with the corresponding position of nozzle on also be provided with the pattern of expression respective nozzle jet properties and characteristics, not only improved integral aesthetic property, and simplified distinguishing and selection work of nozzle, make the shower nozzle handover operation more convenient clear.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within the protection domain of the present utility model.
