  In the hand-held electrostatic sprayer, the electrostatic application electrode is exposed to the outside, and a problem remains in safety.

  Further, the present invention further includes a method of covering the periphery of the electrostatic application electrode with an electrode holder for safety with respect to the electrostatic application electrode, and safely cleaning the electrostatic application electrode portion located inside the electrode holder. An object of the present invention is to provide a hand-held electrostatic sprayer that can be easily performed, has good operability, and can improve the efficiency of electrostatic spraying operation.

  In order to solve the above-mentioned problems, a hand-held electrostatic spray bottle according to the present invention covers an electrostatic application electrode, an electrostatic spray nozzle, and the periphery of the electrostatic application electrode and the electrostatic spray nozzle at the tip of the soot tube. An electrode holder having an appropriate number of window holes is provided, a booster coil is disposed in the vicinity of the electrostatic application electrode, and a handle is connected to the rear end of the soot tube. A first state in which an application ON / OFF switch and a spray liquid passage opening / closing means are provided, the electrostatic application ON / OFF switch (15) is ON, and the spray liquid passage opening / closing means (20) is opened; A second state in which the application ON / OFF switch (15) is OFF and the spray liquid passage opening / closing means (20) is open; and the spray liquid passage opening / closing means (in which the electrostatic application ON / OFF switch (15) is OFF and 20) At least in the closed third state It is possible with the arrangement switched to three states (claim 1).

  In the handheld electrostatic sprayer of the present invention configured as described above, the safety of the electrostatic application electrode can be improved and the electrostatic application electrode part can be cleaned safely and easily. That is, since the electrostatic application electrode is covered with the electrode holder and is not exposed to the outside, safety is improved.

  In the present invention, in the second state, that is, in a state where the electrostatic application ON / OFF switch is turned off, the spray liquid passage opening / closing means is opened, and cleaning liquid is supplied from the electrostatic spray nozzle. The electrostatic application electrode portion can be cleaned safely and easily.

  For example, at the end of the electrostatic spraying operation, with the electrostatic application ON / OFF switch turned off, an appropriate amount of fresh water is put into the spray liquid tank, and the spray liquid passage opening / closing means is opened while closing the front surface of the electrode holder, and the fresh water The electrostatic application electrode part can be safely and easily cleaned by simply spraying and draining from the window hole formed in the electrode holder, and a cleaning tool such as a dedicated brush is appropriately inserted from the window hole formed in the electrode holder. By doing so, the said electrostatic provision electrode part can be cleaned more reliably. Therefore, it is preferable that the window hole formed in the electrode holder has a size that does not hinder insertion of the cleaning tool.

  When the electrostatic spraying operation is continued, the electrostatic application electrode part is cleaned, and sprayed droplets and other impurities adhere to the electrostatic application electrode part, and a moisture layer containing such impurities is formed. Since leakage may occur and normal electrostatic spraying may not be performed, it is necessary to perform it at an appropriate time or at the end of the electrostatic spraying operation. The first state is an electrostatic spraying operation state, and the third state is a state at the end of the electrostatic spraying operation.

  The spray liquid supply hose is connected to a rear end portion of the lower branch pipe. Therefore, compared with the case where the spray liquid supply hose is directly connected to the rear end of the gripping part, the load of the spray liquid supply hose is not directly applied to the rear end of the gripping part, and the spray liquid The handling of the supply hose is easy, the operability of the spray bottle is improved, and the working efficiency is improved.

  In one embodiment of the present invention, the electrostatic application ON / OFF switch provided on the upper surface portion of the upper branch pipe formed in the grip portion is a slide switch, and the spray provided on the upper surface of the lower branch pipe The liquid passage opening / closing means may be a spray liquid passage opening / closing cock.

It can also be constituted by a switch (claim 4).

  According to this embodiment, when the spraying work side is selected with the work state selection ON / OFF switch and the spray liquid passage opening / closing means is opened / closed, the pressure switch is turned ON / OFF to be electrostatically applied. On the other hand, if the cleaning operation side of the ON / OFF switch for selecting the work state is selected, the pressure switch is always turned OFF and the cleaning liquid that is not electrostatically applied is discharged. The electrostatic application electrode portion can be safely cleaned.

  One embodiment of the present invention is a cock switch in which the electrostatic application ON / OFF switch and the spray liquid passage opening / closing means are integrally formed.

  Such a cock switch is, for example, capable of rotating in two directions from an operation position in which electrostatic application is OFF and the spray liquid passage is closed, and when the spray liquid passage is opened by rotating in one direction, By setting the electricity application ON / OFF switch to be ON, and setting the electrostatic application ON / OFF switch to remain OFF when the spray liquid passage is opened by rotating to the other side, The operation can be switched from the operation stop state to the spraying operation state and the cleaning state with one operation, and the restriction on the attachment position is reduced.

  In one embodiment of the present invention, the inside of the grip portion is a battery housing portion (Claim 6).

  According to this embodiment, the wiring from the power source can be simplified, and the power line or the like is not connected to the periphery of the grip portion, so that the operability of the soot tube is improved.

That is, the electrostatic display lamp that is turned on or blinks when the normal static electricity is applied is turned off when a trouble such as leakage of applied voltage occurs.

  In addition, when the electrostatic display lamp is made to blink, it is easier for an operator to confirm that normal electrostatic application is applied in, for example, an electrostatic spraying operation in fine weather as compared with a case where the electrostatic display lamp is always lit. In addition, when trouble such as leakage of the applied voltage occurs, the light is extinguished, so that it is possible to quickly avoid chemical spraying without an electrostatic effect.

  In one embodiment of the present invention, a battery indicator lamp that displays battery consumption is provided adjacent to the electrostatic charge lamp provided on the upper surface of the grip portion.

  According to the embodiment, the electrostatic effect is confirmed by confirming at a glance the confirmation of normal electrostatic application by the electrostatic display lamp that is lit or blinking at the time of normal electrostatic application and the consumption of the battery. It is possible to quickly avoid the chemical spray without water.

  According to the handheld electrostatic sprayer of the present invention, the safety of the electrostatic application electrode can be improved, and the electrostatic application electrode part can be cleaned safely and easily, and the operability is good.
