Defined technical assignment and specified target are realized basically by high pressure water spray machine comprising in one or more Technical characteristic disclosed in appended claims.

Description of the drawings

Further features and advantages of the present invention will become clearer by following description, therefore unrestricted, excellent Choosing, but be not unique high pressure water spray machine embodiment in shown attached drawing, wherein：

Fig. 1 shows the schematic diagram of high pressure water spray machine according to the present invention；

Fig. 2 shows the schematic diagrames of some components of the high pressure water spray machine in Fig. 1；

Fig. 3 shows the schematic diagram of the technical solution of the replacement of Fig. 2.

Specific implementation mode

In the accompanying drawings, reference numeral 1 indicates high pressure water spray machine.High pressure water spray machine is a kind of device, and surface is allowed to pass through Liquid sprays to clean to them.Due to the pressure of high pressure water spray machine injection, surface can be mechanically cleaned.Preferably, But it is not essential, this hydrojet includes water, may there is the detergent of addition.

The high pressure water spray machine 1 includes a booster pump 2, for the wash liquid that pressurizes.

The preferably piston pump of this pump 2.It includes multiple pistons, and alternated travels are executed in corresponding cylinder.Piston pump It is well known in the present art, therefore does not further describe.

High pressure water spray machine 1 further comprises the motor for starting the pump 2.

This motor 3 suitably moves all pistons of pump 2 simultaneously.Advantageously, this motor 3 is brush motor.

The high pressure water spray machine 1 includes can be by an ON/4 of user activated high pressure water spray machine 1.Switch 4 also wraps An operating space 42 is included, permission/prevention is for being supplied to the electric current of motor 3 to pass through.Preferably, this switch is one two-way Switch.It interrupts phase and neutral gear.

High pressure water spray machine 1 further includes device 5, if it exceeds when the overvoltage of predetermined critical occurs, the device is for stopping Motor 3.This mistake is pressed in pump 2 and is detected.Overvoltage can be along washing as possible (not preferred solution) The access (for example, in downstream of pump) that liquid flows into is detected.

The stop device 5 includes a microswitch 50.The microswitch further includes operation part 502, its permission/prevention Supply passing through for the electric current of motor 3.In general, the microswitch 50 is to be closed, and only serve as opening when pressure life.The switch 4 and microswitch 50 be electrically coupled.The switch 4 and microswitch 50 are placed along the electricity suppl pipeline of motor 3.Therefore, switch 4 And/or the opening of microswitch 50 prevents the power supply of motor 3.

The stop device 5 includes actuator 51, has served as extruding current, activation microswitch 50.

The actuator 51 be included in the first position presented in normal course of operation and presented under overpressure situation second The moving parts shifted between position, in the event of excess pressure, it activates microswitch 50 to stop power supply and is supplied to motor 3.

Typically, which is mechanical actuator.Therefore it is pushed by the overvoltage generated in pump, and in stroke Middle activation microswitch 50.

Minimum range between the operating area 42 of switch and the operation part 502 of microswitch is less than 10 lis Rice, preferably smaller than 5 centimetres, more preferably less than 2 centimetres.

In this fashion, since two components are substantially very close to each other, the cost of necessity wiring is minimum.Group It fills also faster.

In the first embodiment (referring to Fig. 2)：

The microswitch 50 includes protection shell 501；Operation part 502, permission/prevention are located at 501 electric current of shell Pass through, and internal positioned at shell 501 (which define a kind of shells).Typically, in the first configuration operation part 502 permits Perhaps electric current passes through, and prevents electric current from passing through in the second configuration；Second configuration of the operation part 502, which corresponds to, to be previously described Actuator 51 the second position；

The switch 4 includes protection shell 41：Operating area 42, allow/prevent electric current from passing through, and it is located at the shell In body 501：In general, operating area 42 in the first configuration allows electric current to pass through, electric current is prevented to pass through in the second configuration.

In such first embodiment, the protection shell 501 of microswitch 50 and the protection shell 41 of switch 4 are detachable Ground connects.Particularly, the protection shell 501 of microswitch 50 is directly connected to the shell 41 of switch 4, without any insertion Element.

As shown in the embodiment of fig. 2, the shell 41 of switch 4 includes the selector 410 for starting high pressure water spray machine 1, The selector 410 is defined as directly being activated by user.Selector 410 allows the operating area 42 in permission/prevention electricity Switch between the first configuration and the second configuration that stream passes through.

The shell 501 of microswitch 50 and the shell 41 of switch 4 are in direct contact.

Microswitch 50 and switch 4 include for electric current by connector 6.It the shell 501 of the microswitch 50 and opens The shell 41 of pass 4 is mechanically connected to each other by connector 6.

Connector 6 includes at least one open component 61 and corresponding female element 62, they can be connected with each other.Open component 61 It extends to 501 outside of shell of microswitch 50 or 41 outside of shell of switch 4, the female element 62 is accommodated in microswitch In 50 shell 501 or the shell 41 of switch 4.

In second embodiment (referring to Fig. 3), switch 4 and microswitch 50 include a common protection shell 7.

The common protection shell 7 include for activating switch 4 selector 410, the switch be intended to directly by with It activates at family.

Preferably, selector 410 is button.

The present invention so conceived is so that be possible to realize multiple advantages.

Firstly, since switch and microswitch are very close each other, allow the cost reduction of wiring.Being immediately adjacent to each other can permit Perhaps a region is formed, the region special protection switch and microswitch can be to avoid the water of present position.More further, with can The mode of removal is directly connected to both parts and is conducive to assembling speed.

The present invention so conceived is easy to carry out many modification and variation, and all these both fall within embodies the invention In the range of principle.In addition, all details could alternatively be other technical equivalent components.In practice, used institute There are material and size, can be any type as needed.
