Description

[Detailed Description of the Invention] This invention relates to an electric sprayer in which a liquid tank is detachably attached to the lower surface of a drive case.

This type of sprayer is used by a worker hanging it from the waste.

Therefore, as the worker moves, the chemical solution in the liquid tank sways in response to the worker's steps, creating waves.

The collision of these waves causes powerful droplets to be scattered toward the chemical exchange port of the liquid tank, so even if a backing is interposed between the liquid tank side and the drive unit case,
The chemical solution is forced to leak from this part.

Therefore, this idea involves loosely fitting a floating body into the liquid suction pipe that hangs down inside the liquid tank from the side of the drive unit case.
This suppresses the generation of droplets due to the wave motion of the chemical solution during use, eliminating the risk of leakage from the chemical solution exchange port.

An embodiment of this invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing an example of an electric sprayer according to this invention. In the figure, 1 is a drive case housing a pump (not shown), etc., 2 is a liquid tank, and 3 is a liquid tank 2. This is the chemical solution exchange port.

Reference numeral 4 denotes a connecting member rotatably supported on the side wall of the drive unit case 1, and the distal end engaging portion 5 of the connecting member 4 is connected to the liquid tank 2.
The liquid tank 2 is fixed to the lower surface of the drive unit case 1 by engaging with the engagement recess 6 formed in the drive unit case 1 .

7 is a discharge port connected to a sprayer (not shown), and 8 is an annular backing attached to the lower surface of the drive unit case 1.

A liquid suction pipe 9 is vertically installed on the lower surface of the drive unit case 1, and extends from the chemical liquid exchange port 3 into the liquid tank.

As shown in FIG. 2, a floating body 10 made of an elastic material such as rubber is loosely fitted into the liquid suction pipe 9.

Reference numeral 11 denotes a liquid suction tube insertion hole formed in the floating body 10.

By providing this floating body 10, even if the liquid tank 2 swings as the operator moves during spraying and the chemical solution M inside ripples as shown in FIG. 3, the floating body floats on this chemical solution M. 10 suppresses the generation or force of the droplets that are likely to be generated due to the ripples of the chemical solution M, and even when the ripples are significant, the droplets move along the liquid suction pipe 9 and are sprayed as shown by the dashed line in FIG. 3. Since the exchange port 3 is coated, the possibility that the chemical solution M leaks to the outside from the annular backing 80 portion fastened between the drive unit case 1 and the liquid tank 2 is eliminated.

The floating body 10 is not limited to an elastic material, and may be made of wood or styrofoam resin, but it is preferably formed of the above-mentioned elastic material in consideration of the fact that it can be bent from the chemical solution exchange port 3 and inserted into the liquid tank 2. .

Further, as long as the size of the floating body 10 is large enough to close the chemical exchange port 3, a sufficient splash prevention effect can be achieved.

As described above, this invention can provide an electric sprayer that can reliably prevent splashes of chemical liquid generated during use from leaking out of the liquid tank by installing a floating body on the chemical liquid in the liquid tank. .
