Description
Technical field
The utility model belongs to sprayer art, relates to a kind of knapsack sprayer in particular.
Background technology
Sprayer is the abbreviation of spraying equipment.Sprayer utilizes suction effect that liquid medicine or other liquid are become vaporific, is ejected into the utensil on other objects equably, is made up of compressed-air actuated device and tubule, nozzle etc.
Knapsack sprayer generally includes cylindrical shell, rocking bar, piston, piston rod, piston cylinder, drive link, fluid reservoir, filling opening, spray lance, shower nozzle, switch, plastic, rubber pipe etc., in use, in cylindrical shell, liquid is added by filling opening, filling opening lid is sealed, then cylindrical shell is carried on the back after one's death, user holds spray lance properly on the other hand, another hand-drive rocking bar moves up and down, rocking bar passes through drive link, piston rod drives piston to move in piston cylinder, and carry out the pressure of fluid reservoir to increase, open switch, liquid will spray from shower nozzle after plastic, rubber pipe and spray lance move from fluid reservoir.
In use, when user's drive rocker moves up and down, because arm normal activity position and cylindrical shell are not on same position, arm is on front side of health, and cylindrical shell is on rear side of health, rocking bar one end and cylindrical shell hinged, so now rocking bar need longer, arm needs up and down scope larger drive link, piston rod and the piston of could driving to pressurize to fluid reservoir, user in use frequently on a large scale up and down arm be easy to feel to ache; And in use to when pressing down rocking bar, cylindrical shell crank can be caused and be partial to rocking bar one side, user then need expend larger strength maintenance balance due to rocking of cylindrical shell, and rocking of cylindrical shell is unfavorable for spraying operation simultaneously; Particularly when the liquid in cylindrical shell is less, the total quality of cylindrical shell is less, and during drive rocker, whole cylindrical shell rocks more obvious, and cylindrical shell and rocking bar associated movement simultaneously, user cannot continue to pressurize to fluid reservoir.
And user must carry out independent drive rocker with a hand in use, and only a surplus hand takes spray lance to spray, then it is lower to carry out nebulization efficiency.
Utility model content
For the deficiencies in the prior art, the utility model provides one and more meets human body limb scope of activities, is user-friendly for pressurization, avoids the knapsack sprayer expending unnecessary muscle power.
For achieving the above object, the utility model provides following technical scheme: a kind of knapsack sprayer, comprise cylindrical shell and be arranged on the fluid reservoir on cylindrical shell, cylindrical shell offers filling opening, and fluid reservoir is connected with rubber tube, and rubber tube is connected with spray lance, spray lance is provided with switch and shower nozzle, spray lance is provided with grip part, and on spray lance, corresponding grip part is provided with pressue device, is connected with forcing pipe between pressue device and fluid reservoir.
By adopting technique scheme, in use, first in fluid reservoir, liquid is added by filling opening, filling opening is sealed, shoulder cylindrical shell, then hand-held spray lance, shower nozzle is aimed at thing to be painted, when user holds grip part, just manipulate pressue device by the same hand, pressue device is undertaken fluid reservoir to pressurize by forcing pipe, and pressure process carries out inconvenience and large-scale drive rocker without the need to re-using another hand, that avoids the unnecessary activity on a large scale of arm to cause aches, and uses convenient; Simultaneously when pressurizeing, owing to having broken away from the up and down of rocking bar, then the pressure to cylindrical shell when avoiding pressurization, has namely avoided cylindrical shell is rocked back and forth and the inconvenience that causes to user, even if when liquid is little in cylindrical shell, also can carry out pressurization operation.
The utility model is set to further: pressue device comprises piston cylinder, piston, piston rod and pressure hand, piston cylinder is fixed on spray lance, piston is positioned at piston cylinder, piston rod is through grip part and piston rod two ends connect piston and pressure hand respectively, pressure hand one end and spray lance is hinged, presses between hand and spray lance and is provided with Compress Spring.
By adopting technique scheme, when carrying out pressurized operation, the grip part of spray lance and pressure hand are held by palm simultaneously, palm carries out firmly, then press hand extruding Compress Spring, moved in piston cylinder by piston rod driven plunger simultaneously, thus by forcing pipe, fluid reservoir is pressurizeed, then unclamp pressure hand, popped into position counter for pressure hand by Compress Spring, again holding pressure hand carries out firmly, so repeatedly, just can constantly the pressure in fluid reservoir be increased, very easy to use, even if when opening switch and spraying, also can carry out operation so repeatedly to pressurize.
The utility model is set to further: grip part offers the through hole passed for piston rod, and corresponding through hole, grip part is provided with leakproof wall.
By adopting technique scheme, piston rod is through grip part, when carrying out spraying operation, liquid will flow through in spray lance, increase leakproof wall, then avoid liquid to flow out from the gap between piston rod and grip part, simultaneously liquid can between leakproof wall and the inwall of grip part by spraying to shower nozzle.
The utility model is set to further: between forcing pipe and rubber tube, binding is fixing.
By adopting technique scheme, being fixed between forcing pipe and rubber tube, avoiding the scratching when operating of too much pipeline to foreign material, to make it more neat, avoid unnecessary trouble.
The utility model is set to further: spray lance is provided with two.
By adopting technique scheme, because pressue device is arranged on the grip part of spray lance, without the need to pressurizeing with a hand more separately, then can arrange two spray lances, two spray lances carry out spraying operation simultaneously, and nebulization efficiency is more increased simultaneously.
Compared with prior art, the utility model knapsack sprayer meets human body limb scope of activities more, is user-friendly for pressurization, avoids expending unnecessary muscle power, improves the efficiency of spraying operation simultaneously.
