Accompanying drawing explanation
Further features and advantages of the present invention be will become clearer from by following description, the most non-limit
System, it is preferred that but be not the embodiment of unique high pressure water spray machine in shown accompanying drawing, wherein:
Fig. 1 shows the schematic diagram of the high pressure water spray machine according to the present invention；
Fig. 2 shows the schematic diagram of some parts of the high pressure water spray machine in Fig. 1；
Fig. 3 shows the schematic diagram of the technical scheme of the replacement of Fig. 2.
Detailed description of the invention
In the accompanying drawings, reference 1 represents high pressure water spray machine.High pressure water spray machine is a kind of device, and it allows
Surface is cleaned to they injections by liquid.Due to the pressure of high pressure water spray machine injection, therefore can machinery
Ground cleans surface.Preferably, but not necessarily, this hydrojet includes water, may have the detergent of interpolation.
This high pressure water spray machine 1 includes a booster pump 2, is used for the wash liquid that pressurizes.
This pump 2 is preferably piston pump.It includes multiple piston, and it performs alternated travels in corresponding cylinder.
Piston pump is well known in the present art, and does not further describes.
High pressure water spray machine 1 farther includes the motor for starting this pump 2.
This motor 3 moves all pistons of pump 2 the most simultaneously.Advantageously, this motor 3 is to have brush
Motor.
This high pressure water spray machine 1 includes can be by user activated high pressure water spray machine 1 a ON/4.Open
Closing 4 and also include an operating space 42, it allows/stops for being supplied to the electric current of motor 3 to pass through.Preferably,
This switch is a two-way switch.It interrupts phase place and neutral gear.
High pressure water spray machine 1 also includes device 5, and during if it exceeds the overvoltage of predetermined critical occurs, this device is used
In stopping motor 3.This mistake is pressed in pump 2 and is detected.Possibility (not preferred solution) is so
Overvoltage can along wash liquid flow into path (such as, in the downstream of pump) be detected.
This stop device 5 includes a microswitch 50.This microswitch also includes operation part 502, it
Passing through of the electric current of permission/prevention supply motor 3.Generally, this microswitch 50 is Guan Bi, and and if only if
Overvoltage is opened when occurring.This switch 4 and microswitch 50 are electrically coupled.This switch 4 and microswitch 50
Electric supply line along motor 3 is placed.Therefore, the opening of switch 4 and/or microswitch 50 stops motor
The power supply of 3.
This stop device 5 includes actuator 51, has served as extruding now, and it activates microswitch 50.
This actuator 51 is included in the primary importance presented in normal course of operation and presents under overpressure situation
The second position between displacement mobile parts, in the event of excess pressure, it activate microswitch 50 stop electricity
Source is supplied to motor 3.
Typically, this actuator 51 is mechanical actuator.Therefore it promoted by the overvoltage produced in pump, and
And in stroke, activate microswitch 50.
Minimum range between described operating area 42 and the operation part 502 of microswitch of switch is little
In 10 centimetres, preferably smaller than 5 centimetres, more preferably less than 2 centimetres.
In this fashion, due to two parts the most each other, the cost of necessary wiring is
Little.Assemble the most faster.
(see Fig. 2) in the first embodiment:
-this microswitch 50 includes protective housing 501；Operation part 502, it allows/stops to be positioned at housing
Passing through of 501 electric currents, and it is internal to be positioned at housing 501 (which defining a kind of shell).Typically,
Operation part 502 in one configuration allows electric current to pass through, and stops electric current to pass through in the second configuration；Described
Second configuration of operation part 502 is corresponding to the second position of previously described actuator 51；
-this switch 4 includes protective housing 41: operating area 42, it allows/stop electric current to pass through, and position
In described housing 501: generally, the operating area 42 in the first configuration allows electric current to pass through, second
Configuration stop electric current pass through.
In such first embodiment, the protective housing 501 of microswitch 50 and the protective housing of switch 4
41 is detachably connected.Especially, the protective housing 501 of microswitch 50 is directly connected to switch the shell of 4
Body 41, and there is no the element of any insertion.
As shown in the embodiment of fig. 2, the housing 41 of switch 4 includes the choosing for starting high pressure water spray machine 1
Selecting device 410, described selector 410 is defined as directly being activated by user.Selector 410 allows described operation
Region 42 switches between the first configuration allowing/stop electric current to pass through and the second configuration.
The housing 501 of microswitch 50 directly contacts with the housing 41 of switch 4.
Microswitch 50 and switch 4 include the adapter 6 passed through for electric current.The shell of this microswitch 50
The housing 41 of body 501 and switch 4 is mechanically connected to each other by adapter 6.
Adapter 6 comprises at least one open component 61 and corresponding female element 62, and they can be connected with each other.
Open component 61 extends to outside the housing 501 of microswitch 50 or outside the housing 41 of switch 4, described the moon
Element 62 is accommodated in the housing 501 of microswitch 50 or the housing 41 of switch 4.
In the second embodiment (seeing Fig. 3), switch 4 and microswitch 50 include a common protection
Housing 7.
This common protective housing 7 includes a selector 410 for activating switch 4, and this switch is intended to
Directly activated by user.
Preferably, selector 410 is button.
So the present invention of design is hence in so that likely realize multiple advantage.
Firstly, since switch and microswitch are the most each other, it allows the cost of wiring to reduce.Mutually
Next-door neighbour can allow to form a region, and this region special protection switch and microswitch can avoid present position
Water.More further, it is directly connected to both parts removably and is conducive to assembling speed.
So present invention of design is prone to carry out many amendments and deformation, all these both falls within the embodiment present invention
In the range of inventive concept.Additionally, all details could alternatively be the parts that other is the most equivalent.?
In practice, all material used, and size, can be any as required.
