Abstract
The utility model discloses a switch handle of a valve, comprising a handle base and a handle cover, wherein a flow passage is arranged in the handle base, and a valve is arranged in the flow passage. The utility model is characterized in that the handle base is hinged with a press hand which can control opening or closing of the valve, an inductive switch connected with a water pump is installed in the handle base, and the press hand is provided with an inductive switch magnet matched with the inductive switch. The utility model can control the inductive switch connected with the water pump to act by the inductive switch magnet on the press hand. When a sprayer stops spraying, the water pump can stop working in time. Thus, the utility model has the advantages of being beneficial for improving the service life of the water pump, reducing the power consumption of the water pump and extending the power supplying time of batteries.
Description
Technical field
The utility model relates to a kind of valve switch handle, particularly a kind of valve switch handle that is applied on the sprayer.
Background technique
In agricultural production,, need spray insecticide in order to prevent the harm of disease and pest to crop.Usually usefulness is hand sprayer, and this sprayer mainly comprises explosive barrel, pump, spray boom shower nozzle and switch knob.Traditional sprayer switch handle comprises a switch main body, and an end of switch main body is connected with handle, and spool is installed in the switch main body, the foreign trader is connected with spanner at spool, spanner and switch main body are hinged, and valve is in opening state when pressing down spanner, and sprayer is realized auto spraying.Adopt the sprayer of this switch knob can not be in time by this switch knob control of pump startup and close, when closing, the sprayer bat-handle switch can not water pump be quit work, thereby water pump can be in a period of time under the high pressure conditions and moves, thereby can reduce the working life of water pump, increase the power consumption of sprayer.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of out-of-work valve switch handle of water pump that can in time make when sprayer stops to spray.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of valve switch handle, comprise handle base and handle cover, be provided with liquid chunnel in the described handle base, valve is installed in the liquid chunnel, it is characterized in that being hinged with on the described handle base pressure hand, the unlatching of described pressure hand may command valve or close is equipped with the induction switch that is connected with water pump in handle base, press the induction switch magnet that cooperates with induction switch is installed on hand.
As the utility model preferred embodiment, described valve comprises that one is arranged on the valve body on the handle base, valve body is provided with the hole that communicates with liquid chunnel, valve seat is installed in the valve body, valve ball is installed in the valve body, between valve ball and the valve body spring is installed, depression bar is installed in the valve seat, one end of depression bar contacts with valve ball, and the other end extends to outside the valve seat and with pressing hand and cooperates.
As the improvement of the above-mentioned mode of execution of the utility model, the bottom of described valve seat is equipped with first seal ring, and second seal ring is installed between valve seat and the valve body, and the 3rd seal ring is installed between valve seat and the depression bar.
The beneficial effects of the utility model are: the induction switch action that the utility model can be connected with water pump by the induction switch magnet control of pressing on hand, when stopping to spray, sprayer can water pump be quit work, help improving the working life of water pump, reduce water pump power consumption, prolong battery-powered time.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a perspective exploded view of the present utility model;
Fig. 2 is a working state sectional view of the present utility model;
Fig. 3 is a closed condition sectional view of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the disclosed a kind of valve switch handle of the utility model comprises handle base 1 and handle cover 2, and handle cover 2 is fixed on the handle base 1 by retaining screw 3, and handle retaining screw lid 4 is installed on the handle cover 2.In handle base 1, be provided with liquid chunnel 5, in the liquid chunnel 5 valve is installed, on handle base 1, be hinged with pressure hand 7 by latch 6, the wherein unlatching of these pressure hand 7 may command valves or close, induction switch 8 is installed in handle base 1, induction switch 8 is connected with water pump by induction switch line 9, on pressure hand 7 the induction switch magnet 10 that cooperates with induction switch 8 is installed.
As shown in the figure, in the present embodiment, above-mentioned valve comprises that one is arranged on the valve body 11 on the handle base 1, valve body 11 is provided with the hole 12 that communicates with liquid chunnel 5, and valve seat 13 is installed in the valve body 11, and valve ball 14 is installed in the valve body 11, between valve ball 14 and the valve body 11 spring 15 is installed, depression bar 16 is installed in the valve seat 13, and an end of depression bar 16 contacts with valve ball 14, and the other end extends to outside the valve seat 13 and with pressing hand 7 and cooperates.
Working principle of the present utility model is: when pressing hand when pressing down, press on hand induction switch magnet and distance induction switch when 3～5mm of induction switch open, water pump is started working; Depression bar is depressed valve ball it is separated with first seal ring simultaneously, and liquid is flowed out from liquid chunnel; Otherwise, will press the hand return, the distance of pressing on hand induction switch magnet and induction switch greater than 5mm when above induction switch disconnect, water pump quits work, the while, spring was with valve ball top return, with the first seal ring closure.
The induction switch action that the utility model can be connected with water pump by the induction switch magnet control of pressing on hand, when stopping to spray, sprayer can water pump be quit work, help improving the working life of water pump, reduce water pump power consumption, prolong battery-powered time.
