Description

Sprayer manual booster pump

Technical field:

The utility model relates to the technical field of sprayers, in particular to a manual pressure pump for sprayers.

Background technique:

Sprayers are often used in the field of agricultural production. The existing manual sprayer adopts a rocker structure. When in use, it needs to be shaken several times to generate a certain pressure, so that the liquid in the liquid storage tank is sprayed out, and the use effect is poor.

Utility model content:

The purpose of this utility model is to provide a sprayer manual pressurized pump for the deficiencies of the prior art, which can generate greater pressure each time it is manually operated, so that the liquid in the matching liquid storage tank can be sucked out very easily And it sprays outwards, which can reduce the user's operating intensity, and the use effect is better.

In order to achieve the above object, the utility model adopts the following technical solutions:

It includes a piston sleeve and an intermediate liquid storage tank. There is a piston rod inside the piston sleeve. A piston is fixed at the lower end of the piston rod, and a handle is installed at the upper end of the piston sleeve. There is a water inlet at the bottom of the piston sleeve. There is a first movable piece; the lower end of the piston sleeve communicates with the middle liquid storage tank, the middle liquid storage tank has a liquid inlet, the liquid inlet is matched with a second movable piece, and the middle liquid storage tank also has an output pipe.

The piston sleeve is provided with a first blocking plate that limits the moving range of the first movable plate; the intermediate liquid storage tank is provided with a second blocking plate that limits the moving range of the second movable plate.

The beneficial effect of the utility model is that when in use, the output pipe is closed, and when the piston rod is pressed down, the middle liquid storage tank is filled with high-pressure gas; The first movable piece enters the piston sleeve, and when the piston rod is pressed down again, the liquid in the piston sleeve pushes away the second movable piece of the intermediate liquid storage tank and enters the intermediate liquid storage tank, opens the output pipe, and passes through the intermediate liquid storage The high-pressure gas in the box can produce a better spray effect.

Fig. 2 is the structural representation of the second embodiment of the utility model

Fig. 3 is the structural representation of the third embodiment of the present utility model

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

See accompanying drawings 1-3, the utility model comprises piston sleeve 1, intermediate liquid storage tank 2, and piston sleeve 1 has piston rod 3, and the lower end of piston rod 3 is fixed with piston 4, and the upper end passes through piston sleeve 1 outside And a handle 5 is installed, the piston 4 is locked on the piston rod 3 through the screw 6; the bottom of the piston sleeve 1 has a water inlet, and the water inlet is equipped with a first movable piece 7; the lower end of the piston sleeve 1 communicates with the intermediate liquid storage tank 2 , the middle liquid storage tank 2 has a liquid inlet, the liquid inlet is matched with a second movable piece 8, the middle liquid storage tank 2 also has an output pipe 9, and the output pipe 9 is externally connected to the nozzle.

The piston sleeve 1 is provided with a first stopper 10 that limits the movement range of the first movable piece 7, and the first movable piece 7 can realize limited movement up and down at the water inlet; the middle liquid storage tank 2 is provided with The second blocking piece 11 that limits the movement range of the second movable piece 8, the second movable piece 8 can realize limited movement at the liquid inlet.

When in use, close the output pipe 9, when the piston rod 3 is pressed down, the middle liquid storage tank 2 is filled with high-pressure gas, and when the piston rod 3 is pulled up, the liquid in the external liquid storage tank can push back the first movement of the piston sleeve 1 piece 7 enters the piston sleeve 1, and when the piston rod 3 is pressed down again, the liquid in the piston sleeve 3 pushes away the second movable piece 8 of the intermediate liquid storage tank 2 and enters the intermediate liquid storage tank 2, and the output pipe 9 is opened. , through the action of the high-pressure gas in the intermediate liquid storage tank 2, a better spray effect can be produced.

Fig. 1 is the schematic diagram of the first embodiment of the present utility model, and the lower end side of piston sleeve 1 communicates with the bottom of intermediate liquid storage tank 2, and the second movable plate 8 is arranged on the bottom of intermediate liquid storage tank 2, and the second movable plate 8 Horizontal setting, moving along up and down.

Fig. 2 is a schematic diagram of the second embodiment of the present utility model, the lower end side of the piston sleeve 1 communicates with the lower end side of the intermediate liquid storage tank 2, and the second movable plate 8 is arranged on the joint between the piston sleeve 1 and the intermediate liquid storage tank 2 At the communicating position, the second movable piece 8 is arranged vertically and moves along the left and right directions.

Fig. 3 is a schematic diagram of the third embodiment of the present utility model, the lower end side of the piston sleeve 1 communicates with the lower end side of the intermediate liquid storage tank 2, and the second movable plate 8 is arranged on the joint between the piston sleeve 1 and the intermediate liquid storage tank 2 At the communicating position, the second movable piece 8 is arranged horizontally and moves along the up and down directions.

The utility model makes high-pressure gas form in the middle liquid storage tank 2 through the up and down movement of the piston rod 3, and simultaneously utilizes the opening and closing of the first and second movable plates 7 and 8 to realize liquid extraction, thereby producing better spray effect.

The above descriptions are only preferred embodiments of the present utility model, and do not limit the scope of protection of the present utility model.
