A so-called patterned mop in which a handle is simply connected to the mop portion cannot be realized by retrofitting the wax storage portion without changing the mop. That is, the wax storage 72 and the long handle 71a, which are integrated with the popular type mop with a handle, are provided.
In order to apply, the handle of the mop with handle must be cut short and connected to the long handle 71a. Then,
On the contrary, when the wax storage section 72 is not necessary and is removed, only the handle extending from the mop section and cut once is too short to work.

In order to apply wax to a large area floor, it is convenient and efficient to provide a wax storage 72 and supply the wax from the wax storage 72 to the mop 70 at any time. When the floor of a small area is targeted, the wax storage 72 is unnecessary and rather bulky, and even if it is empty, the handle 71 becomes heavy to some extent. Further, the lever 74 for supplying the wax from the wax storage 72 is provided at the upper end of the long handle 71a, and the inside of the long handle 71a is connected to the wax storage 72 side, so that the position of the lever 74 is fixed. , It cannot be adjusted to a position that is convenient for the operator.

Therefore, in view of the above problems, the present invention can be easily used in the form of a usual mop with a handle depending on the work situation, and by easily attaching the wax storage section to the handle when necessary. The purpose is to provide a waxing tool which is easy to use and easy to use.

That is, a valve seat 37 having a seat portion 38 facing the inside of the lower cylinder portion 31 from the hole 32 of the lower cylinder portion bottom wall 31a is provided by being bonded to the lower surface of the bottom wall 31a of the lower cylinder portion. The valve seat 37 is a main body 37 made of a perforated resin plate.
A ring-shaped rubber packing is adhered to a, and this rubber packing portion serves as a seat portion 38. A valve ball 35 can be seated on a seat portion 38 at the periphery of the through hole 39 of the valve seat 37. One end of a rod 36 which is fixed by penetrating the valve ball 35 and the other end of the valve housing portion 30 are provided. The coil spring 40 is stretched between the locking pin 41 and
The valve ball 35 is lightly biased in the seating direction. The locking pin 41 is arranged across the diameter of the valve housing portion 30.

A string 45, such as a resin thread, is connected as a connecting material to the other end of the rod 36 fixed to the valve ball 35. The string 45 extends upward in the tank body 11, and the small hole 25 of the partition wall 24 and the cap. It is pulled out to the outside of the neck 20 through the small hole 26 of the cap 20a.
It is connected to the handle ring 50 (see FIG. 4) near 0a.

On the other hand, 2 is provided at the lower end opening of the valve housing portion 30.
The cap 30a to which the resin tube 55 of the book is attached is fixed, and each resin tube 55 is opened in the valve housing portion 30. 6A and 6B show a state in which the resin tube 55 is attached to the cap 30a. FIG. 6A is a partial cross-sectional side view, and FIG. 6B is a BB arrow view in FIG. However, the mounting bracket is omitted in (b). The resin tubes 55, 55 are located on the lower side of the cap 30a during the construction work, that is, the groove portion 1 of the tank body 11.
It is biased toward the back wall side where 5 is formed. Also the center line L

For 0, it is directly below the valve 34 and faces forward (direction opposite to the handle 5).
Is provided with a small hole 43.

In the state where the wax is stored in the tank body 11, the valve ball 35 is kept seated on the valve seat 37 by its own weight and the tensile force of the coil spring 40. On the other hand, as shown in FIG.
The valve ball 35 is moved away from the seat 38 of the valve seat to allow the wax to pass through the through-hole by hooking one finger of the hand gripping the handle ring 50 and pulling it up. As a result, the wax is removed from the two resin tubes 55.
It will flow down through.

When the valve is opened, the wax flows down from the through hole of the valve seat in the shape of a thick string, and depending on the inclination of the tank body 11 during the construction work, the valve accommodating portion 3
0 It is possible that the wax is biased toward one of the two resin tubes 55 that open at the lower end, but since the coil spring 40 is arranged directly below the through hole of the valve seat, wax does not flow with the coil spring 40. The particles are scattered by the collision and are evenly supplied to the openings of the two resin tubes 55, 55. At this time, since the opening of the resin tube 55 is located on the lower side of the cap 30a, the valve 3
The wax that has passed through 4 is supplied to the mop portion side through the resin tube 55 without being substantially accumulated in the bottom portion of the valve housing portion 30. Further, since the inside of the valve housing portion 30 is communicated with the outside through the small hole 43 in the upper portion, the wax flows down the resin tube 55 smoothly without any resistance.

FIG. 8 shows a guide holder for holding the vicinity of the tip of the resin tube. In the figure, (a) is a plan view, (b) is a sectional view taken along the line AA in (a), and (c) is a perspective view. The guide holder 8A is formed by obliquely raising an inclined block 57 from a flat base 56, and the inclined block 57 is provided with a hole 58 through which one resin tube 55 can pass in the plate thickness direction. . The tilted block 57 is arranged so as to be offset to the lateral end of the horizontally long base 56, and a small hole 59 is formed on the side of the base 56 where the tilted block 57 is not located. As shown in FIG. 8 (d), the guide holder 8B is configured such that the lateral bias of the inclined block 57 with respect to the base 56 is reversed.

As shown in FIG. 1 above, in the case of a flat mop type in which the mop portion 1 is flat and the string of the mop 3 is short,
The guide blocks 8A and 8B are attached to the upper surface of the flat plate-shaped mop holder 2 by inclining the inclined blocks 57 forward. As a mounting means, the back surface of the base 56 may be fixed to the mop holder 2 with a double-sided adhesive tape, or may be fixed with a screw through the small hole 59 of the base 56.
Since the hole 58 of the tilted block 57 that is tilted forward is directed obliquely downward and forward, the resin tube 55 inserted into this hole 58 is guided to the front near the mop, and the wax is supplied immediately before the mop 3.

The guide holders 8A and 8B are not limited to the above-mentioned modes, but can be used in other modes. That is, as shown in FIG. 9, in the case of a type in which the mop 3'of a string having a long mop portion is held by the block-shaped mop holder 2 ', the inclined block 57 is tilted upward on the vertical surface of the front edge of the mop holder 2'. Guide holder 8A, 8B
Can be attached. As a result, the hole 58 of the inclined block 57 is directed obliquely downward and forward, so that the resin tube 55 inserted into this hole is guided forward to supply wax to the mop 3 ′.

Further, since the inclined blocks 57 are arranged so as to be biased in the lateral direction of the base 56, there is an obstacle such as a protrusion in the left and right directions of the guide holder mounting surface of the mop holder 2 or 2'and the mounting of the base 56. Even when the range is limited, the degree of freedom of position of the tip portion of the resin tube 55 can be expanded.

In this embodiment, as described above, the wax tank 10 for storing wax is attached to the handle 5, and the handle ring 50 is attached to the string 45 extending from the valve ball 35 inside and extending from the cap 20a of the neck portion 20. Connect
Since the resin tube 55 extends from the bottom of the wax tank 10 to the mop part 1 and the vicinity of the tip thereof is held by the guide holders 8A and 8B attached to the mop holder 2, it is only necessary to put a finger on the handle ring 50 and pull it. The wax in the wax tank 10 can be supplied to the mop unit 1 via the resin tube 55. At this time, in order to pull the handle ring 50, it is only necessary to bend the finger hooked on the handle ring 50 in a natural direction while holding the handle 5.
When the desired amount is supplied to the mop unit 1, it is only necessary to remove the finger, so the operation is extremely simple.

Since the wax tank 10 is attached to the handle 5 by the mounting bracket and the fastener 7, the floor surface has a different flatness, the office equipment or the desk is a narrow and complicated place,
Various patterned mops with different types of mops are used depending on the construction object such as the vertical wall of the stairs.Easy to attach and detach to any patterned mop, making it suitable for each construction site. It has the advantage that it can be installed efficiently while being replaced.

Further, since the valve in the valve housing portion 30 is composed of the valve ball 35 and the valve seat 37,
Even if the wax is emptied from the tank body 11, the valve ball 35 easily separates from the seat surface only by pulling the handle ring 50, so that the valve may stick, unlike a cock type ball valve or the like. Nor.

Further, in the neck portion 20 of the wax tank,
A partition wall 24 is provided on the upper cylinder portion 21 of the tank body 11, and a cap 20 a is fixed to the upper end opening of the tank body 11.
And the cap 20a has a string 45 at the center.
Since only the small holes 25 and 26 through which the handle 5 is passed are provided, even if the wax tank 10 falls sideways with the handle 5 due to the handle 5 falling down, the partition wall 24 and the cap 20a.
Since there is a leak prevention space between them, the wax does not leak from the cap portion. Further, during the waxing work, it is necessary to violently move the mop part back and forth on the floor surface, but in this case as well, the partition wall 24 suppresses the wax liquid surface that vibrates violently. Similarly, the space between the partition wall 24 and the cap 20a serves as a leakage prevention space, and the wax does not leak from the cap portion.

The guide holders 8A and 8B that hold and guide the vicinity of the tip of the resin tube 55 raise the inclined block 57 obliquely from the flat base 56, and the resin tube 55 extends in the plate thickness direction of the inclined block 57. Since the hole 58 is formed to pass through, the mop holder 2 can be attached to a substantially horizontal surface or a vertical surface, and can be used regardless of the shape of the mop holder 2.
The tip of 5 can be guided.

In the embodiment, the valve ball 35 is pulled by the coil spring 40 in order to urge it to the seat portion 37 of the valve seat. However, the present invention is not limited to this, and the compression spring is arranged above the valve ball. Then, the valve ball may be pressed against the valve seat. Although the string 45 is used to connect the valve ball 35 and the handle ring 50, a thin rod may be used for connection.
Then, the handle ring 50 is used as an operation unit for opening the valve.
However, this is not limited to the ring shape, and may be, for example, a T-shaped handle on which a finger can be hooked.
