Electric sprayers used for gardening etc. store a chemical solution mixed with the desired chemical in a chemical solution tank.
The chemical solution is sucked up by a pump and sent to a spray rod,
It is designed to spray toward flowers, trees, etc. from the nozzle at the tip of the spray rod. Examples of the above-mentioned chemicals include insecticides and drug spreading agents, but since these types of chemicals generally have a higher specific gravity than water, they gradually settle over time, and some of them settle at the bottom of the chemical solution tank. As a result, the concentration of the chemical solution sprayed from the spray rod changes over time, which has the disadvantage that the spraying effect of the chemical solution also varies.

ができる。 When spraying a chemical solution, a desired chemical solution is mixed into water to a predetermined concentration, and the chemical solution is put into the chemical solution tank 2, the spray rod 15 is held, and the switch 12 is turned on. Then, the motor 7 starts and the pump 8 starts operating, and the chemical liquid in the chemical liquid tank 2 is sucked into the liquid suction pipe 13 from the liquid suction port 17, and further sent to the spray rod 15 through the hose 14, and is sprayed. It is ejected from the nozzle 15a at the tip of the rod 15. Then, while operating the spray rod 15, the chemical solution jetted from the nozzle 15a is sprayed onto trees and the like. As mentioned above, the specific gravity of this type of drug mixed into the drug solution is generally higher than that of water, and therefore, as time passes, the drug in the drug solution tends to gradually settle to the bottom of the drug solution tank 2. In this device, when the switch 12 is turned on to start the pump 8, the power supply voltage is also applied to the stirrer 16, causing the stirrer 16 to vibrate.The vibration is propagated into the chemical solution and stirs the drug. sedimentation is prevented. Furthermore, since the stirring bar 16 is disposed directly above the bottom surface of the chemical liquid tank 2, the drug that has settled on the bottom surface of the chemical liquid tank 2 floats to the surface due to the stirring action of the stirring bar 16, and is widely dispersed in the chemical liquid, so that it remains constant from beginning to end. A chemical liquid having approximately a predetermined concentration can be sent to the spray rod 15. Furthermore, even if there is a lump of drug in the drug solution, the lump is broken down by the vibration of the stirrer 16 and dispersed in the drug solution, so that the lump of drug is sucked into the liquid suction tube 13. liquid suction pipe 13 and spray rod 15
There is no possibility that the pump 8 will become clogged or the pump 8 will malfunction. Furthermore, if the stirrer 16 is attached to the flexible liquid suction pipe 13 as described above, the stirrer 16
Since the liquid suction pipe 13 also vibrates in the lateral direction along with the vibration, the effect of stirring the chemical liquid can be further improved.
この撹拌子として、液中で回転させるフアンを
用いることが、例えば特開昭50−107513号公報に
より提案されているが、フアンが回転することに
より泡立ちが生じ、この泡立ちは液量が少ないと
き特に著しく発生し、このため吐出ポンプが泡を
一緒に吸い上げ、脈動吐出現象を起こし、これが
ため不快な異音が生じるとともにノズルから散布
される薬液量が不均一となり、万遍なく散布する
のがむずかしくなる。 For example, it has been proposed in Japanese Patent Application Laid-Open No. 107513/1983 to use a fan that rotates in the liquid as the stirrer, but the rotation of the fan causes foaming, and this foaming occurs when the amount of liquid is small. This is especially noticeable, and as a result, the discharge pump sucks up the bubbles together, causing a pulsating discharge phenomenon, which causes an unpleasant noise and makes the amount of chemical sprayed from the nozzle uneven, making it difficult to spray evenly. It becomes difficult.
しかし圧電素子を用いることにより薬液は揺り
状に撹拌され不必要な泡立ちを生じることがな
く、脈動吐出が防止でき異音もなく、しかも均一
散布が行なえる。 However, by using a piezoelectric element, the chemical liquid is agitated in a oscillating manner, and unnecessary foaming does not occur, pulsating discharge can be prevented, and there is no abnormal noise, and moreover, uniform dispersion can be performed.

FIG. 4 shows another embodiment of the present invention, in which a mounting rod 22 is vertically provided on the lower surface of the base plate 4, and the stirring bar 16 is attached to the lower end of the mounting rod 22. The stirrer 16 is located near the lower end of the liquid suction pipe 13. Also, the stirrer 16
Lead wires 18, 18 for applying voltage to are routed within the mounting rod 22. In such a configuration, when the switch 12 is turned on, the chemical liquid flows into the liquid suction pipe 1.
3 is sucked in from the lower end and sent to the spray rod 15, and the stirrer 16 vibrates near the lower end of the liquid suction pipe 13 to stir the chemical liquid. As described above, the stirrer 16 may be attached to the liquid suction pipe 13 as shown in the first embodiment, or the attachment rod 22 may be provided in addition to the liquid suction pipe 13 as in this embodiment. It may also be attached to the mounting rod 22. In this case as well, if the mounting rod 22 is made of a flexible material, the mounting rod 22 will vibrate together with the stirrer 16, thereby further increasing the effect of stirring the chemical solution.

As explained above, the electric sprayer 1 according to the present invention
This is an electric sprayer 1 equipped with a chemical liquid tank 2, a chemical liquid supply pump 8 driven by a motor 7, and a spray rod 15 connected to the pump 8. 16, the chemical liquid is stirred by the stirring bar 16. In particular, since this stirring bar uses a piezoelectric element that converts electrical energy into vibration, the foaming of the chemical liquid that occurs when using a mechanical stirring bar is avoided. The chemical solution can be directly stirred in a shaking manner without causing any turbulence, and variations in the concentration of the chemical solution can be prevented.

According to the present invention, these can be prevented.
