The lower end of moving part 163 is formed with open laterally a plurality of pin 163a, keeps a determining deviation each other between a plurality of pin 163a.This is because the upper side of pin 163a is used to support an end that compresses spring 164, and the space is the washing agent continuation inflow downwards that is used to make by the through hole inflow of stopper 161 between pin 163a and the pin simultaneously.
On the one hand, in order to prevent that through hole from stopper 161 to the external leaks washing agent, needing to be provided with an extra hermetically-sealed construction between valve part and connector 120.So, be formed with extension 165 to connector 120 with certain-length from the back side of stopper 161; The rear of extension 165 is formed with the U font groove is set; Be formed with dividing plate 123 from the bottom surface of connector 120 to stopper 161 sides.At this moment, groove and dividing plate 123 are set vis-a-vis; Be provided with and be provided with O type ring 167 in the groove.So the actual space that flows into liquid detergent is restricted to the inner space of extension 165 in first space 121.
Then, there is the main body 130 with second space 131 lower end of connector 120 by the screw secure bond; The left surface of main body 130 is combined with compression unit 140; The left side of compression unit 140 is provided with above-mentioned motor and cam.At this moment main body 130 is the open cylinders in two sides, and the upper end of main body 130 combines with the lower end of connector 120, and the lower end of main body 130 combines with drain hose 190.Be formed with second space 131 in the inside of main body 130 in addition and air flue 133, the second spaces 131 alongst form, air flue 133 is to second space, 131 supply air.Also have, the outside, upper end of main body 130 is formed with a plurality of secure bond timbers 135, by the lower end of secure bond timber 135 usefulness screw secure bond at connector 120.
On the one hand, main body 130 open two ends are provided with seal member 170,180, and seal member 170,180 only to second space, 131 supply compressed air the time, is used to make washing agent to discharge to drain hose 190.
On the one hand, main body 130 open two ends are provided with seal member 170,180, and seal member 170,180 only to second space, 131 supply compressed air the time, is used to make washing agent to discharge to drain hose 190.
Be arranged on first seal member 170 of main body 130 upper ends in the seal member and keep opened state when flat, only the time to second space, 131 supply compressed air, airtight second space 131 and first space 121.For this reason, the bottom of connector 120 is divided into the space of first space 121 and bottom by section holder 125, and section holder 125 has the formation of certain width ground along connector 120 lower inside side faces.Lower space is the space that is used for 170 liftings of first seal member.At this moment, in order to pass through first seal member, 170 complete closed, first space 121 and the lower space, the back side shape of first seal member 170 and section holder 125 forms accordingly.As an embodiment, be the center with the bar gage 171 that keeps first seal member, 170 elevating movement benchmark, the tabula board 173 (skirt) of seal member 170 bottoms is the bells that form downwards slowly to tilt; The back side of section holder 125 also forms inclined plane slowly, and is corresponding with tabula board 173.
So when second space 131 flows into compressed air, along with first seal member 170 rises and combine closely in the back side of the section holder 125 of connector 120, complete closed first space 121 and second space 131.
In addition, be arranged on second seal member 180 of main body 130 lower ends and be in airtight state when flat, only open compressed-air actuated the time flowing into, washing agent is flow in the drain hose 190 to second space 131.For this reason, second seal member 180 is made of flow channel tube 181 and compression seal portion 185, and flow channel tube 181 is combined in the lower end of main body 130, and stream has the washing agent in second space 131; Compression seal portion 185 combines closely in the outer periphery of flow channel tube 181 simultaneously along with compressed air can expand.
Compression unit 140 is made of key casing 143, button 145 and spring 147, and key casing 143 is combined in the side of main body 130, forms discharge chambe 141; Button 145 be arranged near a side of cam (cam) 155 when its during to main body 130 side shiftings, the volume of minimizing discharge chambe 141; Spring 147 is used for button 145 is reset to original state.At this moment, in order to form discharge chambe 141, the side that key casing 143 will be only when its during to main body 130 side shiftings, the volume of minimizing discharge chambe 141; Spring 147 is used for button 145 is reset to original state.At this moment, in order to form discharge chambe 141, key casing 143 is with the one side open that only combine with the air flue 133 of main body 130, and remaining part is all sealed.In addition, button 145 is arranged on and the corresponding another side of key casing 143 open surfaces; The two ends of spring 147 are supported on the inside face of button 145 and the one side of key casing 143, resiliency supported button 145 respectively.
At this moment, for the motion compresses air by button 145, the part that is positioned at key casing 143 inside in the button 145 needs fully closely to be combined on the inside face of key casing 143.But, when preferably the inside face of button 145 and key casing 143 is combined closely, a button sealing 149 that moves with button 145 additionally is set, so that keep the air-tightness of discharge chambe 141.Button sealing 149 not only can ensure compressed-air actuated generation, and the washing agent that can also prevent to flow into by air flue 133 is through being provided with the problem towards external leakage of button 145.
Then, the lower end of main body 130 is inserted with drain hose socket 191 across second seal member 180, and drain hose socket 191 is combined on the drain hose 190.At this moment can not to be combined in what write in compression seal portion 185 original copys that constitute second seal member 180 be compression seal portion 175 to drain hose socket 191, consider the expansion of compression seal portion 185, drain hose socket 191 need keep a determining deviation with compression seal portion 185.
Then, the motor 153 of the side of compression unit and axle are combined in the cam cam155 on the motor 153, optionally press the button 145 of compression unit when rotating on the cam 155.At this moment motor 153 is installed in the inside that prolongs the motor housing 151 that forms from connector 120, is supported on the back side of top panel.
