The specific embodiment

Set forth an embodiment of the present utility model below in conjunction with accompanying drawing.It is made up of housing 6, shell 7, spanner 5, piston element 1, stifle 8, bung flange 9, head cap 2, branch water jacket 3, plunger 4.Be housing 6 in the shell 7, there is pit 61 housing 6 one ends 62, are plunger 4 on the pit 61, and are porose on the plunger 4, and branch water jacket 3 is arranged on plunger 4, and dividing on the water jacket 3 has aperture 31, and aperture 31 is not on minute water jacket 3 cylinder axis, and 62 have the head cap 2 of being with centre bore 21 in the end.Lateral aperture 63 and upright opening 64 are arranged in the housing 6, and the two communicates, and piston element 1 is arranged in upright opening 64; Bung flange 9 is arranged on the housing 6, is stifle 8 in the bung flange 9, is piston element 1 in the endoporus 81 of stifle 8, and spanner 5 one ends stretch out outside the shell 7, are connected with housing 6 by bearing pin 51, and spanner 5 one ends are spanners 52, and the other end is to pull holder 53, and pulling in the holder 53 is piston element 1.

Described piston element 1 is to be made of piston, steel ball 16, spring 18, piston is made of upper pedestal 11, saddle 17, interior claw type tooth 12, dimple 13, frustum 14, insertion post 15, upper pedestal 11 can slide in upright opening 64, the pedestal of upper pedestal 11, saddle 17, dimple 13, frustum 14, insertion post 15 fuse, dimple 13 is arranged in the upper pedestal 11, be steel ball 16 in the dimple 13, interior claw type tooth 12 is arranged on the dimple 13, make steel ball 16 can not leave the space that interior claw type tooth 12 surrounds; Saddle 17 is arranged above the interior claw type tooth 12, and spring 18 1 ends are on saddle 17, and the other end is close to the upper surface of upright opening 64, insert post 15 and stretch in the endoporus 81 of stifle 8, and closely cooperate, inversed taper platform 82 is arranged on the stifle 8, frustum 14 is positioned on the inversed taper platform 82, and the two is in conjunction with sealing.Inserting on the post 15 Lower Half faces of cylinder has four planes 151, and when moving on inserting post 15, air can flow into from the slit that plane 151 and endoporus 81 form.

Described head cap 2 has a centre bore 21, connectivity slot M22 and connectivity slot N23, and when connectivity slot M22 communicated with aperture 31, liquid was sprayed from centre bore 21 through connectivity slot M22 from aperture 31; When connectivity slot N23 communicated with aperture 31, liquid was sprayed water from centre bore 21 through connectivity slot N23 from aperture 31.When not communicating, be closed condition.

When the utility model uses, as shown in Figure 8.Rotate head cap 2 earlier, connectivity slot, centre bore 21 are communicated with the aperture 31 that divides water jacket 3.At this moment hand is pressed the spanner 52 of spanner 5, it is around bearing pin 51 deflections that are positioned on the housing 6, the other end of spanner 5 was pulled holder 53 upper pedestal 11 was upwards moved this moment, spring 18 is compressed, and the aperture 31 of the liquid in upright opening 64 through lateral aperture 63 and branch water jacket 3, the connectivity slot of head cap 2, centre bore 21 outwards spray.This moment, upright opening 64 interior pressure were higher than the pressure in the container, steel ball 16 presses on the dimple 13, and the liquid that can not in the upright opening 64 is back in the container, owing to moving on the insertion post 15, produce negative pressure in the container, at this moment gas 151 flows into the slit of endoporus 81 from the plane in the atmosphere.When hand is no longer pushed spanner 52, spring 18 resets, inserting post 15 moves down, frustum 14 fits tightly sealing again with inversed taper platform 82, make pressure in the upright opening 64 less than the pressure in the container, liquid in the container backs down the steel ball 16 that is positioned on the dimple 13, and the liquid in the container is flowed in the upright opening 64 by suction pipe 10.Continue to push spanner 5, repeat above-mentioned spraying or water spray.When not using the utility model, only need head cap 2 half-twists are closed hydrojet.
