However, like the hand cleaners shown in Patent Documents 1 to 3 above, if the PET bottle is used as a handle as it is, the PET bottle is not necessarily formed in a shape or diameter that is easy to grip, and therefore, in a long cleaning operation, gradually. It became heavy and the work became difficult.
Also, if you use the PET bottle itself as a handle, you may grip the PET bottle strongly when you apply care to remove the persistent dirt during the cleaning process. There were times when too many were going out.
In addition, when a force is applied to the hand holding the plastic bottle, a large force is applied to the connecting part between the sliding contact body such as a brush and the plastic bottle. There was also a risk that the cleaning liquid inside would spill out.

On the other hand, if a handle formed in a shape or diameter that is easy to grip in advance, like the hand cleaner shown in Patent Document 4, the various problems described above are solved or alleviated, but in Patent Document 4, Since the PET bottle is attached to the back of the handle that is the fulcrum (the direction opposite to the direction in which the brush is attached), when you try to press the brush against the part to be cleaned, the weight of the cleaning liquid in the PET bottle is reversed. Therefore, a reverse force that moves the brush away from the portion to be cleaned acts.
Therefore, it is necessary to continuously apply the force against the reverse force during the cleaning work, and if the cleaning work takes a long time, the burden on the worker increases and there are many women with particularly weak power. Considering the environment expected to be used, it has not always been an easy-to-use hand cleaner.

The cleaning work is performed in a horizontal posture with the grip 5 held horizontally.

In this case, the operation grip 5 is gripped by four fingers excluding the index finger of one hand and the palm, and the index finger is put on the operation piece 13 to perform the cleaning work.
When the cleaning liquid S in the plastic bottle P mounted in a downward inclined posture is ejected from the nozzle 47 with respect to the bottle mounting unit 3, the operating piece 13 is rotated toward the operation grip 5 by pulling the index finger forward. Let
When the operation piece 13 rotates, the connecting rod 51 is moved to the cylinder chamber 45 side, and the piston 49 at the tip of the connecting rod 51 enters the cylinder chamber 45 to contract the biasing spring 53.

As the piston 49 moves, the inside of the cylinder chamber 45 is pressurized, the first valve body 41 is closed, the second valve body 43 is opened, and the cleaning liquid S flowing into the cylinder chamber 45 is opened. The nozzle 47 is passed through the second valve body 43 and the discharge-side second tube 39, and a predetermined amount corresponding to the operation amount of the operation piece 13 is discharged from the nozzle 47 toward the site to be cleaned W.
At this time, since the check valve 31 is closed, the flow of the cleaning liquid S from the check valve 31 to the outside is prevented.

On the other hand, when a necessary amount of the cleaning liquid S is discharged from the nozzle 47, the force of the index finger pulling the operation piece 13 is weakened and the operation piece 13 is rotated toward the sliding contact body 7 side. At this time, since the urging force in the extending direction by the urging spring 53 is constantly applied to the operation piece 13 via the connecting rod 51, the operation piece 13 is moved toward the sliding contact 7 by the urging force of the urging spring 53. It automatically returns to the original rotated state, the inside of the cylinder chamber 45 becomes negative pressure, the first valve body 41 is opened, the second valve body 43 is closed, and the first tube 37 on the supply side is discharged from the discharge side. The flow of the cleaning liquid S into the second tube 39 is stopped, and the cleaning liquid S in the PET bottle P flows into the cylinder chamber 45 through the supply port 29 and the first tube 37 on the supply side, and the next Prepare for injection.
Note that the check valve 31 shifts to an open state and allows external air to flow into the plastic bottle P to prevent a pressure drop in the plastic bottle P.

Next, with the operation grip 5 held against the site to be cleaned W on which the cleaning liquid S has been applied, the sliding contact body 7 is moved back and forth to remove the dirt adhering to the site to be cleaned W.
In the same manner, the discharge of the cleaning liquid S and the wiping operation with the sliding contact body 7 are repeated a predetermined number of times to perform the cleaning operation for a necessary area.
Further, when cleaning the tile joints or the like, the sliding contact body 7 is replaced with the sliding contact body 7 for the joint, and the cleaning work is performed.

(2) When used in a vertical posture (see FIGS. 6, 11 (e) and 12)
For example, when the window glass standing upright in the vertical posture is used as the site to be cleaned W, the wiper type sliding contact body 7 shown in FIG. 11 (e) and FIG. The extension hose 55 is attached to the supply port 29 as shown by the phantom line in FIG.
In this case, as shown in FIG. 12, the hand cleaner 1 of the present invention is held in a vertical posture so as to be held obliquely upward, and the wiper type sliding contact body 7 is moved up and down while being pressed against the site to be cleaned W. Wipe off.

Further, the operation for discharging the cleaning liquid S is the same as that in the case of using the above-described downward horizontal posture. By attaching the extension hose 55, the necessary discharge amount of the cleaning liquid S is maintained until the cleaning liquid S runs out. It is possible to perform cleaning work.
When the hand cleaner 1 of the present invention is used in a vertical posture, the weight G of the cleaning liquid S is not applied to the sliding contact body 7 side, but is supported by the arm of the work clothes through the handle 17 as shown in FIG. Therefore, the sliding contact body 7 can be prevented from wobbling and the window glass or the like can be stably cleaned.

  And according to the hand cleaner 1 of this invention comprised in this way, it is easy to use also for a weak woman and a child, and reduction of the burden concerning an operator is achieved. Then, it becomes possible to provide the hand cleaner 1 having both operability and functionality that can easily adjust the discharge amount of the cleaning liquid S and can cope with various cleaning operations under different conditions.

The hand cleaner 1 of the present invention is not limited to the above-described embodiment, and can be changed within the gist of the present invention.
For example, the position where the nozzle 47 is installed is not limited to the upper front position near the installation site 9 of the sliding contact body 7 described above, but other positions near the installation site 9 of the sliding contact body 7 or the installation site of the sliding contact body 7. 9 itself can be provided.

  Further, the structure for attaching the replaceable sliding contact body 7 to the installation site 9 of the main body portion 19 is not limited to the slide engagement structure 35 described above, and other attachment structures such as a fitting type and a screw type may be adopted.
