Description
One, technical field
The utility model relates to sprayer.
Two, background technology
Shortcomings such as it is big that present sprayer, particularly one of knapsack sprayer ubiquity are born back of the body weight, and the operation physical demands is big, and range of jet is little.Another shortcoming is that hydrojet leaks out between pump pipe and piston, and the piston rod hole by pump pipe cap lid spills again.When spray be toxic liquid the time, this seepage can cause serious harm to spray medicine person, for example agricultural atomizer since the accident that the leakage of agricultural chemicals causes spray medicine person to poison happen occasionally.
Three, summary of the invention
A purpose of the present utility model provides the little sprayer of a kind of labour intensity.
Another purpose of the present utility model provides the sprayer that hydrojet does not leak outside.
The technical solution of the utility model is as follows:
A kind of sprayer, it comprises pump, high pressure fluid reservoir and injection apparatus, it is characterized in that it has the normal pressure liquid storing barrel, the inlet of pump is positioned at the bottom of normal pressure liquid storing barrel, the liquid outlet of pump is connected by the top of tube connector with the high pressure fluid reservoir, and the high pressure fluid reservoir has bottom insert canal, and bottom insert canal links to each other with injection apparatus.The bottom insert canal of high pressure fluid reservoir also can be opened a liquid outlet in the bottom of high pressure fluid reservoir and substitute.
In order to prevent that hydrojet from leaking outside from the piston rod hole on the cap of pump, the design people has invented a kind of pump antiseep sheath (application name in addition is called the patent of " a kind of pump antiseep sheath "), and sprayer of the present utility model can adopt pump antiseep sheath equally.It is to be with the antiseep sheath outside piston rod.The antiseep sheath is flexible pipe or the bellows that a liquid impermeable material is made, its internal diameter is less than the internal diameter of pump pipe, so that put it in the pump pipe, the length of antiseep sheath is not less than the longest distance of pump piston to pump pipe cap lid, the reciprocating motion that guarantees piston does not damage the antiseep sheath, the antiseep sheath is enclosed within outside the piston rod, one end sealing and fixing is on piston, the other end has an outside flange, the external diameter of flange is greater than the internal diameter of pump pipe, piston rod and antiseep sheath are put in the pump pipe, the flange of antiseep sheath can be stuck on the mouth of pipe of pump pipe, screw on the cap of pump pipe, with cap antiseep sheath port sealing is fixed on the mouth of pipe of pump pipe, there is pod apertures the upper end of pump pipe, and pod apertures communicates with the normal pressure liquid storing barrel, the hydrojet that leaks out from the piston clearance can flow back to the normal pressure liquid storing barrel by pod apertures, has guaranteed that hydrojet can not leak outside from the piston rod hole on the cap.
For the ease of pressurizeing to the inflation of high pressure fluid reservoir, the high pressure fluid reservoir of above-mentioned sprayer can be connected with the pressurization inflation and chew.Chew the air that can in the high pressure fluid reservoir, charge into certain pressure in advance by inflation.The piston rod handle is arranged on the piston rod of pump, be used for the tension and compression piston rod.
For the ease of the running of pump, be connected with connecting rod and link rod handle on the piston rod of pump, knapsack sprayer is born the back spraying person, lift the pressure link rod handle, just liquid in the normal pressure liquid storing barrel or air can be pressed in the high pressure fluid reservoir.
Can existing piston rod handle on the piston rod of sprayer of the present utility model, also be connected with connecting rod and link rod handle, connecting rod can be to load and unload connection with being connected of piston rod.
Sprayer of the present utility model is because of having normal pressure liquid storing barrel and high pressure fluid reservoir, therefore can in the high pressure fluid reservoir, be inflated to certain pressure in advance, as 1.5 kilograms of pressure, be pressed into spray liquid with pump to the high pressure fluid reservoir again, if be pressed into the spray liquid of half volume of high pressure fluid reservoir, the pressure of high pressure fluid reservoir just rises to 3 kilograms, sprayer spraying liquid can have enough height, when spraying, can constantly be pressed into spray liquid to the high pressure fluid reservoir, after the liquid of normal pressure liquid storing barrel has been pressed, can add new spray liquid at any time, do not influence the pressure in the high pressure fluid reservoir, therefore as knapsack sprayer, the weight of once bearing can be lighter, reduced labor intensity of operating personnel.
Sprayer of the present utility model can have pump antiseep sheath, has guaranteed that spray liquid can not guarantee operating personnel's safety to external leakage.
Four, description of drawings
