Description

[Detailed description of the invention] This invention relates to the structure of a liquid tank for an electric sprayer that is detachably attached to the lower surface of the drive case and which together with the case constitute the main body of the sprayer. The purpose is to be able to hold a dropper for compounding.

The liquid tank in this type of sprayer is formed in the shape of a bottle by blow molding, with the periphery of the chemical solution exchange port at the top surrounded by an annular projecting wall.

Incidentally, since users frequently use a dropper for dispensing medical solutions, it is desired that the liquid tank be provided with a simple dropper holding means in order to prevent the dropper from being lost.

As a simple example of the above-mentioned stage holding means, it is conceivable to form a pair of protrusions for holding a dropper that face each other in close proximity to each other on the outer wall of the body of the liquid tank, but in the case of blow molding, two protrusions may be formed. If the above-mentioned protrusions are provided facing each other at one location, the outer wall at the base of the protrusion will have uneven thickness and become locally thin, reducing the strength of the body against which water pressure is applied.

Furthermore, if the dropper is installed on the torso, there is a risk that the dropper will fall off if it hits the human body during work.

This idea was made in view of the above circumstances, and by simply forming a protrusion on the top wall of the limb tank, the tank can hold a dropper for dispensing liquid medicine without creating a deflection part, thereby preventing its loss. This was prevented.

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

In FIG. 1, 1 is a drive case housing a built-in motor and pump (not shown); 2 is attached to and detachable from the lower surface of the case 1 via a locking member 3 such as a clamp pivotally attached to the drive case 1; A liquid tank that can be attached freely, in case 1 above.
and constitute a sprayer main body 4.

5 is a hose connected to a spray operation rod (not shown), and 6 is a liquid suction pipe.

The liquid tank 2 is made by blow molding, and the top wall 2
A chemical solution exchange port γ is formed in the center of a, and the peripheral edge of this exchange port γ is surrounded by an annular vertical wall portion 8 that is fluid-tightly joined when attached to the drive unit case 1.

Reference numeral 9 denotes a single protruding portion formed on the top portion 2a at a position close to and facing the vertical wall portion 8, and a dropper 10 for dispensing a medicinal solution is installed between the protruding portion 9 and the vertical wall portion 8. is held elastically.

In the above embodiment, the protrusion 9 is made into one strip for the purpose of simplifying the structure, but if the shape of the dropper 10 is large or long, it is difficult to form a large protrusion 9. Therefore, as shown in FIG. Deflection can be prevented by forming a plurality of small protrusions.

Further, depending on the shape of the dropper 10, a partially flat surface 8a may be formed on the vertical wall portion 8, as shown in FIG. 3, for example.

As described above, since the dropper 10 for dispensing the medicinal solution is held between the protrusion 9 and the vertical wall 8, the user can use the dropper 10
can be easily managed and their loss can be prevented.

In particular, since it is only necessary to form the protruding part 9 at a position facing the vertical wall part 8 of the top wall 2a of the liquid tank 20, uneven thickness of the outer wall of the liquid tank 2 by blow molding is suppressed, and the mechanical strength is sufficiently increased. Furthermore, since the dropper 10 is held in the vertical wall portion 80, the dropper is stored in the space between the lower surface of the drive unit case 1 and the top wall 2a of the liquid tank 20, so that the dropper 10 is stored in the space between the lower surface of the drive unit case 1 and the top wall 2a of the liquid tank 20. There is no risk of it falling off carelessly and being lost.
