For realizing above-mentioned purpose, the utility model adopts following technical scheme:
Hand sprayer; Comprise casing, be installed in the spray gun assembly that casing interior booster pump assembly, rocker assembly and conducting are connected booster pump assembly output; The booster pump assembly comprises the pump barrel of the pressure accumulation jar that is installed in the cabinets cavity, output conducting to pressure accumulation jar, the piston that can slide at the pump barrel inwall; Rocker assembly comprises being connected and is used on the piston drive rocking arm, the rotating connecting rod that is connected on the casing that piston moves that rocking arm is fixed on the connecting rod.
The booster pump assembly also comprises piston fixture, the connector between piston fixture and rocking arm that is fixedly connected with piston, and the upper end of this connector is connected with piston fixture hinge, and the bottom is connected with the rocking arm hinge.
The bottom margin of pressure accumulation jar is connected the edge of the preset installing hole of lower box through a clips, and the bottom that also is provided with the booster pump assembly at lower box is enclosed in inboard protective cover.
Rocker assembly comprises that also vertical fixing is connected the rocking bar of connecting rod one end.
Casing top also is provided with a charge door, and this charge door is provided with a screen pack, and the outer setting of charge door has tank lid.
Also be connected with braces on the casing.
The beneficial effect of the utility model is:
Than prior art, the utility model drives piston up-down through the swing of rocking arm, and to the pressurization of the feed liquid in the casing, it is time saving and energy saving, and is easy to use, and simple in structure, has lower manufacturing cost.
Description of drawings
Fig. 1 is the structural representation of a kind of knapsack hand sprayer of the utility model;
Fig. 2 is the scheme of installation of hand sprayer shown in Figure 1;
Fig. 3 is the cutaway view of hand sprayer shown in Figure 1.
The specific embodiment
Below, in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing:
Like Fig. 1, shown in 2; Be a kind of hand sprayer of the utility model; It comprises water tank 1, rocker assembly 2, booster pump assembly 3 and spray gun assembly 5; Wherein spray gun assembly 5 is installed in the output of booster pump assembly 3, and rocker assembly 2 is when people's hand operated, and the drive booster pump assembly 3 that can continue carries out supercharging.
In conjunction with shown in Figure 3; Booster pump assembly 3 comprises pressure accumulation jar 38, pump barrel 37, piston 34, and wherein the output of pump barrel 37 is connected the input of pressure accumulation jar 38, and piston 34 is arranged in the inner chamber of pump barrel 37; And with the airtight applying of the inwall of pump barrel 37, piston 34 is buckled on the piston fixture 33 through interior back-off.Rocker assembly 2 comprises rocking bar 21, connecting rod 22 and rocking arm 26; Wherein connecting rod 22 horizontal cross-under are preset in the pivoted hole 12 in casing 1 bottom, and connecting rod 22 can rotate with respect to casing 1 thus, and rocking arm 26 is fixed on the connecting rod 22 through two bolts 24; It can be along with connecting rod 22 rotates; Rocking bar 21 vertical fixing are connected an end of connecting rod 22, and the outboard end that staff is controlled rocking bar 21 fluctuates on the rocking bar, and rocking arm 26 can rotate thereupon.Have a connection piece 32 between rocking arm 26 and the piston fixture 33, the bottom of this connector 32 is connected through a loose pin hinge with the free end of rocking arm 26, and its upper end then is connected with piston fixture 33 hinges.Booster pump assembly 3 is packed into by the preset installing hole in casing 1 bottom; The bottom peripheral edge of pressure accumulation jar 38 is fixed on the periphery of this installing hole through a clips 13; Pump barrel 37 is fixed in the pressure accumulation jar 38, and when hand-held rocking bar 21 was up and down, rocking arm 26 swung up and down; Drive piston 34 and move up and down at pump barrel 37 inner chambers, continuable to pressurization in the pressure accumulation pump 38.When rocking arm 26 drive pistons 34 moved downward, pump barrel 37 internal pressures reduced, and the packing ring 35 at pump barrel 37 tops is flicked; Liquid in the casing 1 is pumped in the inner chamber of pump barrel 37, and then, rocking arm 26 promotes piston 34 and moves upward; Pump barrel 37 internal pressures increase, and the packing ring 36 of shutoff between top on the pump barrel 37 and pressure accumulation jar 38 bottoms flicked, simultaneously; Packing ring 35 is in closed state, and at this moment, the liquid in the pump barrel 37 is pumped in the pressure accumulation jar 38; Repeat said process, the final pressure that generation can spray in pressure accumulation jar 38.
