Abstract
Disclosed is an automatic controller for power switch of cleaning machine, comprising a pump body. The pump body is provided with a water inlet and a water outlet, and a magnetic induction switch is installed on the pump body communicating with the water outlet or in the water outlet. The magnetic induction switch is a valve cavity, and a plunger matched with the valve cavity is provided, and a magnet ring is provided outside the plunger rod of the plunger. The plunger is provided with a reset spring, and a magnetic induction element is installed on the outer wall of the valve cavity, and the leading wire of the magnetic induction element is connected with the power switch of the motor. When a water outlet valve is closed, the elevated water pressure in the pump can push the plunger, and the spring can be pressed, and when the magnet ring moves to the central position of the magnetic induction element on the outer wall of the valve cavity along with the plunger, the magnetic induction element is activated (for example, a dry-reed tube is attracted), and the motor power switch is turned off.
Description
Technical field
The utility model relates to the automatic control equipment of cleaning machine (perhaps have and cut out the pump) mains switch.
Background technology
After cleaning machine delivery port spray gun cuts out, if untimely cutting off the electricity supply, pump is working on, and delivery port pressure increases in the recoil pump, the load that can cause pump increases, valve damages in the pump, burns out motor, therefore, prior art connects in the pump housing installs the roof pressure valve in the delivery port, piston by delivery port mesohigh promotion roof pressure valve again by the fork of the long push rod pushing motor sensitive switch that connects piston, reaches the purpose of cutting off motor power.So there is following shortcoming in prior art: the one, volume is big, and the outstanding pump housing has increased whole cleaning machine external form; The 2nd, complex structure, parts are many, the cost height; The 3rd, because push rod contact with the motor sensitive switch, the infiltration of generation can enter circuit, cause in the time of seriously casing charged with the consequence that burns out motor.
Summary of the invention
The utility model adopts the existing defective of roof pressure valve control motor sensitive switch in order to overcome in the existing clear water machine, provides a kind of volume little, makes whole cleaning machine external form dexterity and helps the casing design; Lead line and water source are contactless, cleaning machine mains switch automatic control equipment safe in utilization.
The technical scheme of the utility model cleaning machine mains switch automatic control equipment is: a pump housing is arranged, the pump housing has water inlet and delivery port, it is characterized in that being communicated with on the pump housing of delivery port or in the delivery port magnetic induction switch is installed, described magnetic induction switch is a valve pocket, a piston that matches with valve pocket is arranged, and the piston rod of piston is installed magnet ring outward, and piston has back-moving spring, at the valve pocket outer wall magnetic induction part is installed, the lead-in wire of magnetic induction part connects electric power switch.When cleaning machine cuts out flowing water Valve (being that the shower nozzle spray gun cuts out); utilize in the water pump or the water pressure pushing piston in the delivery port; spring by compression; make the outer magnet ring of piston rod produce displacement; when magnet ring moves to the center of the magnetic induction part (for example tongue tube) of valve pocket outer wall, activated magnetic induction switch, through transmission motor power is closed; motor quits work automatically, and protection pump and motor etc. are avoided high pressure and damaged.
Description of drawings
Fig. 1 is the utility model cleaning machine mains switch automatic control equipment structural representation.
Embodiment
The utility model discloses a kind of cleaning machine mains switch automatic control equipment, be chiefly directed on the pump housing, the pump housing 2 has water inlet 1 and delivery port 8, magnetic induction switch can be installed on the pump housing that is communicated with delivery port (as shown in Figure 1), perhaps be directly installed in the delivery port 8, only delivery port 8 done little improvement design.Described magnetic induction switch is a valve pocket, perhaps with delivery port 8 as valve pocket, a piston that matches with valve pocket 7 is arranged, the piston rod of piston is installed magnet ring 6 outward, piston has back-moving spring 4, can have cock cap 3 to block spring 4 in mouthful, at the valve pocket outer wall magnetic induction part 5 is installed, for example can select tongue tube for use, the lead-in wire of magnetic induction part connects the mains switch of motor.Working as flowing water Valve during work closes, hydraulic pressure in delivery port and the water pump increases and has promoted piston 7, spring 4 by compression, when magnet ring 6 moves to magnetic induction part 5 centers of valve pocket outer wall along with piston 7, activate magnetic induction part (tongue tube adhesive), the mains switch of motor is closed, and motor shuts down.This control device can be widely used in any pump working, also can be applicable in the relevant air pump.
