Abstract
The utility model relates to an automatic switch of a washing machine. The utility model comprises a group of washing machine pump heads. An automatic valve assembly is arranged inside the pump head, the pump head is connected with a switch box, and a power supply switch is arranged inside the switch box, the automatic valve assembly is adopted as a valve seat, a valve rod is arranged inside the valve seat, and one end of the valve rod is matched with a push rod, the valve rod is provided with a returning spring, a top rod having the same body with the valve rod is arranged inside the high-pressure water cavity of the pump head, and the other end of the push rod is matched with the power supply switch of a motor arranged inside the switch box. When the high-pressure water pushes the top rod to move forward to compress the spring, and the high-pressure water discharges the load through a small hole, thereby the pressure is increased after the spay gun is turned off, and the advance distance of the top rod and the valve rod is lengthened, so as to make the push rod held against on the switch, and then the power is off, and the motor stops operating. But when the spay gun is opened over again, the press of the water cavity is decreased, and the valve rod and the push rod are reset by the spring, then the switch is turned on and the motor starts operating.
Description
Technical field
The utility model relates to the automatic switch of cleaning machine or power spraye, is mainly used in flushing vehicle and building surface and atomizers spray agricultural chemicals etc.
Background technology
Self-propelled vehicle such as automobile, motor bike two, dust, muddy water can be stain in the surface in motion, often need to clean.In addition, modern building surfaces such as house are also wanted clean, keep clean and tidy Chang Xin, thereby have promoted the development of cleaning machine.Though the kind of cleaning machine is more, convenient not enough in the use at present, for example when the unexpected withdraw from use of cleaning machine, when closing spray gun, water can spring back over valve and pump chamber from the jet pipe of shower nozzle, and motor is often continuing operation, and trouble is taken in forward and backward operation into account.And when bringing into use, motor and spray gun two switches are difficult to coordinate.Above-mentioned reason can conserve water, and work efficiency have certain influence more machine service life.
Summary of the invention
The utility model provides a kind of hydraulic giant to drive motor and starts voluntarily in order to overcome the defective of prior art, and hydraulic giant closes the cleaning machine automatic switch that motor stops automatically.The technical scheme of described cleaning machine automatic switch is: one group of cleaning machine pump head is arranged, the automatic valve assembly is installed in the pump head, pump head connects switch enclosure, source switch is installed in the switch enclosure, is it is characterized in that the automatic valve assembly is a valve seat, valve rod is installed in the valve seat, one of valve rod matches with push rod, valve rod has retracing spring, is equipped with in the high-pressure water chamber of pump head and the push rod of valve rod with one, matches with the source switch of motor in the switch enclosure in the other end of push rod.In order to help regulating, the retracing spring that its valve rod matches is two on first spring and a second spring.The working process of this automatic switch is: make length of spring compressed when high pressure water promotion push rod travels forward, high pressure water is by the aperture off-load in the valve body wall then, closing downstream pressure when spray gun increases, push rod and valve rod stroke is forward increased, valve rod promotes the push rod action, another crown of push rod source switch that powers on like this, PTO Power Take Off quits work motor; And after spray gun is opened the high pressure chest pressure decay, retreat and drive push rod at the effect lower valve rod of retracing spring and move, source switch is opened, the motor entry into service.Realized that spray gun leaves, motor rotation, spray gun closes the automatic switch purpose that motor stops.

The specific embodiment
The utility model relates to the recloser of high pressure such as cleaning machine water spray, be in the pump head 5 of cleaning machine, the automatic valve assembly is installed in pump head 5, and connect a cover switch enclosure assembly set, source switch 12 is installed in the switch enclosure 11, the kind of source switch is more, comprises various prior arts, power lead 13 joining powers of switch 12 and connection motor.Its described automatic valve assembly is a valve seat 6, and valve rod 9 is installed in the valve seat, and special feature is that of valve rod 9 matches with push rod 10, and as shown in Figure 1, match with the source switch 12 of switch enclosure 11 interior motors in the other end of push rod 10.Valve rod 9 has retracing spring, be equipped with in the high-pressure water chamber 4 of pump head and valve rod 9 and piston 2 push rod 3,, make the outer length of spring compressed of valve rod when high pressure water promotes push rod 3 to the motion of valve rod 9 directions with one, at this moment piston moves small distance, and high pressure water is by the off-load of valve body off-load aperture.Increase but close downstream pressure when spray gun, push rod 3 is also strengthened with piston 2 and valve rod 9 strokes forward, spring further is compressed, thereby valve rod 9 has promoted push rod 10, push rod 10 has moved on its another crown, back switch 12, and source switch is closed, and machine operation stops.When the spray gun beginning of spraying water again.High-pressure water chamber pressure reduces, and spring promotes valve rod 9 and drive push rod 10 to reset, and source switch is opened again, motor rotation.Retracing spring for valve rod 9 can be one, and 8 two on big or small first spring 7 and second spring also can be installed, and adopts two springs to help regulating.
Claims (2)
1, cleaning machine automatic switch, one group of cleaning machine pump head is arranged, the automatic valve assembly is installed in the pump head, and pump head connects switch enclosure, and source switch is installed in the switch enclosure, it is characterized in that described automatic valve assembly is valve seat (6), valve rod (9) is installed in the valve seat, and of valve rod matches with push rod (10), and valve rod has retracing spring, being equipped with in the high-pressure water chamber (4) of pump head (5) and the push rod (3) of valve rod with one, matches with the source switch of motor in the switch enclosure in the other end of push rod (10).
2, cleaning machine automatic switch as claimed in claim 1 is characterized in that the retracing spring that valve rod (9) matches is first spring (7) and second spring (8).
