DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a container 1 and a sprayer 10 are combined to form a pesticide spraying device. As the container 1, a commercially available bottle containing drinking water or the like, and the remaining PET bottle utilizing the drinking water or the like inside thereof (hereinafter referred to as a commercially available PET bottle) can be used. The atomizer 10
Is provided with a main body portion 11, a manual operation portion 12 reciprocally provided on the main body portion 11, and a spraying portion 13, and when the manual operation portion 12 is moved forward with respect to the main body portion 11 (for example, an arrow a It is a manual reciprocating continuous spraying type in which the pesticide in the container 1 is sprayed from the spraying unit 13 when it is pushed in the direction) and when it is moved back (for example, when it is pulled in the direction of the arrow b). The body portion 11 is provided with a grip portion 14.

Because of this, a pesticide having a desired effect is put in a container 1, for example, a commercially available PET bottle, and a sprayer 10 is connected to this PET bottle. By holding the gripping portion 14 with one hand and reciprocating the manual operation portion 12 with the other hand, the pesticide in the PET bottle is continuously sprayed.
Spray from. Therefore, it is possible for a person to spray the pesticide on the garden or kitchen garden of a house while holding it by hand.

Next, the form of the sprayer 10 will be described with reference to FIGS. 1 and 2. The main body 11 includes a first chamber 20 and a second chamber 21.
And the ejection hole 22 and the container connecting portion 23, and the first chamber 20 thereof
The second chamber 21 and the ejection hole 22 communicate with each other. First
The cross-sectional area of the chamber 20 is larger than the cross-sectional area of the second chamber 21. The first chamber 20 communicates with the suction pipe 25 via the suction valve 24, and the ejection hole 22 communicates with the spray section 13. The container 1 is connected to the container connecting portion 23, and the suction pipe 25 is inserted into the container 1. When the manual operation unit 12 is operated to reciprocate, the volume of one of the first chamber 20 and the second chamber 21 increases and the volume of the other decreases, and at the same time, the liquid (pesticides) is constantly stored in the first chamber 20 and the second chamber 21. I am satisfied.

Because of this, if the volume of the first chamber 20 is decreased and the volume of the second chamber 21 is increased by operating the manual operation part 12 in one direction (for example, the direction of arrow a), the first chamber 20 will be increased.
Part of the pesticide therein flows into the second chamber 21, and the remaining pesticide is sprayed from the spray unit 13 through the ejection holes 22. If the volume of the first chamber 20 is increased and the volume of the second chamber 21 is decreased by operating the manual operation part 12 in the other direction (for example, the direction of arrow b),
The pesticide in the container 1 passes through the suction pipe 25 and the suction valve 24 to
It is sucked into the chamber 20. The pesticide in the second chamber 21 is sprayed from the spray unit 13 through the ejection holes 22.

The container connecting portion 23 is fitted and attached to the outer pipe 30 and has a female screw portion 39. The female screw portion 39 is to be screwed with the male screw portion 3 of the mouth portion 2 of the container 1. For example, the male screw portion of the mouth portion of the plastic bottle described above is screwed. The suction valve 24 is connected to the container 2
3 is connected to the first chamber 20 through the hole 30b of the outer pipe 30. Although liquid does not flow from the first chamber 20 to the suction pipe 25 in the suction valve 24,
The liquid flows through the chamber 20. The suction pipe 25 is a resin tube, a metal pipe or the like, and a filter 25a is attached to the tip thereof. Because of this, the suction pipe 25 projects into the container 1 and the pesticide on the bottom can be sucked. Further, by changing the length of the suction pipe 25, it is possible to cope with containers having different sizes (lengths).

The spraying section 13 is provided with an inner cylinder 13a fixed to the tip of the outer pipe 30 and an outer cylinder 13b screwed to the inner cylinder 13a, and the tip of the inner pipe 36 is inserted in the inner cylinder 13a. Fitted and liquid tight. The pesticide circulated in the inner pipe 36 is the hole 13 of the inner cylinder 13a.

Since it does not flow into the suction pipe 25, a part of the pesticide is a gap 3
7, while flowing into the second chamber 21 through the hole 38, the remaining pesticide is pressure-fed into the inner pipe 36 through the gap 37 and is sprayed from the spray unit 13. The second chamber 21 is full of pesticide.

Further, by pulling the rod 33 in the direction of arrow b by grasping and pulling the manual operation part 12 (grip rod 35),
The volume of the chamber 20 increases and the volume of the second chamber 21 decreases.
The pesticide is sucked into the first chamber 20 through the suction pipe 25 and the suction valve 24, and the pesticide in the second chamber 21 flows into the inner pipe 36 through the hole 38 and the gap 37 and is sprayed from the spraying section 13. That is, since the volume of the first chamber 20 is larger than the volume of the second chamber 21, the volume change in the first chamber 20 with respect to the stroke of the rod 33 in the direction of the arrow b is larger than the volume change in the second chamber 21. Since a large amount of pesticide is sucked into the first chamber 20, the pesticide in the second chamber 21 flows into the inner pipe 36 without flowing into the first chamber 20.

Next, a second embodiment will be described. Figure 4
