Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
A kind of extractor electric motor protective device, work for the water suction motor to extractor whether, control, with right
Water suction motor is protected accordingly.Wherein, extractor is mainly made of water suction motor, suction piping and foul water tank, water suction electricity
Machine be connected to by suction piping with foul water tank, absorb water motor for by carpet etc. sewage and foam drawn after pass through suction
Waterpipe is sent into foul water tank.Once the sewage of foul water tank reaches certain water level, water suction motor is difficult to carry out in sewage defeated
It send, if water suction motor continues to work at this time, may have significant impact to its service life.
Therefore, in the utility model preferred embodiment, it is connected by detection foul water tank or with water suction motor air intake vent
(water level information for foul water tank is mainly whether the water level of foul water tank reaches default water to the water level information of the inlet air pipeline connect
Position, the water level information for inlet air pipeline is mainly the mixture for whether having water or foam or water and foam in inlet air pipeline)
It is detected, and then the work of water suction motor is controlled by controller according to the water level information of foul water tank or inlet air pipeline
System.The extractor electric motor protective device specifically includes controller and level switch, and water level sensor is installed on foul water tank or enters
In air piping, wherein the input terminal and level switch of controller are electrically connected, and the control terminal and water suction motor of controller are electrical
Connection, controller receives the water level information of level switch acquisition, and is carried out according to the water level information to the work of water suction motor
Control.Controller is installed on the circuit board of extractor, controller can be extractor itself it is included for water suction motor
The controller that relevant parameter is controlled, be also possible to newly increase is installed on the device washed on mounted circuit board, can use
Microprocessor such as chip microcontroller.
As an implementation, level switch can realize that liquid level sensor is installed on dirt using liquid level sensor
Water level information is acquired in water tank or air intake vent pipeline, the water level information is then sent to control by level switch
Device, such situation are mainly used in the mixture for whether having water or water and foam, and if it is pure foam, it is special to use
Kind of Foam Level Detecting Sensor to realize higher accuracy.When liquid level sensor detects that the water level information of foul water tank reaches default
When having water or foam in water level or inlet air pipeline, controller control water suction motor stop working, when foul water tank water emptying or
When inlet air pipeline does not have water or foam, water suction motor switch is restarted, water suction motor could continue to work normally.
It as the another embodiment of the utility model, please refers to shown in Fig. 1, level switch passes through two metal ends
Son realizes that respectively the first metal end 5 and the second metal terminal 6, the first metal end 5 and the second metal terminal 6 are installed
In foul water tank 7 or inlet air pipeline (not shown), the position of the first metal end 5 and the second metal terminal 6 does not give up restriction, i.e., two
Person can be distributed up and down in foul water tank 7 or inlet air pipeline, can also be distributed with horizontal direction.The first metal end 5 passes through one
First connecting line 3 is connected to the voltage output end of controller 2, and the voltage output end of the controller 2 i.e. port can export centainly
Voltage signal, the second metal terminal 6 is connected to the voltage detection terminal of controller 2, controller 2 by second connecting line 4
Control terminal and water suction motor 1 be electrically connected.It is of course also possible to be the voltage detecting that the first metal end 5 is connected to controller 2
End, and the second metal terminal 6 is connected to the voltage output end of controller 2, i.e. the first metal end 5 and the second metal terminal 6
Position or connection relationship etc. can mutually be fallen, and will not influence control result.Under normal conditions, the first metal end and the second metal end
Son is normally open at energization (being powered by voltage output end), if the water level of foul water tank is not less than preset water level or Gas inlet tube
There are water or foam in road, then the first metal end and the second metal terminal pass through water or foam as medium, and water or foam are simultaneously
When touching the first metal end and the second metal terminal, so that control circuit conducting (has voltage signal to be input to voltage inspection
Survey end) so that the first metal end and the second metal terminal become normally off, controller control water suction motor stops work
Make.When the emptying of the water of foul water tank or inlet air pipeline do not have water or foam, water suction motor switch is restarted, water suction motor could continue
It works normally.
In addition, the extractor electric motor protective device further includes the power supply powered for controller 2, the power supply is it may be said that extractor
The power supply of itself is also possible in addition be arranged.Power supply can be rechargeable battery or other portable powers, be also possible to alternating current 8.
Here by taking alternating current 8 that is to say the power supply of extractor itself as an example, alternating current 8 passes through voltage conversion circuit included inside extractor
(for example including rectification circuit, filter, transformer, reduction voltage circuit etc., being installed on the circuit board of extractor) output meets control
The DC voltage of 2 need of work of device processed, for the power supply of controller 2.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
