Yes. When the outer cylinder 112 is pressed forward against the urging force of the coil spring 124, the engagement state between the pressing convex portion 130 and the claw 127 is released.

  The water storage unit according to the present embodiment has the above-described configuration. Next, an example of its use will be described. As described above, the fixture 101 of the connection joint 3 is fixed to the connection pipe 21 of the ball tap 2 in advance, and the connector 102 to which the hose H is connected is connected as follows. First, the receiving port 110 of the connection tool 102 is inserted and pushed into the insertion port 103 of the fixing tool 101. Then, the claw 127 of the connection tool 102 receives an outward pressing force from the outlet 103 of the fixing tool 101 and retracts into the hole 129 of the connection tool main body 111. A claw 127 protrudes from 129 and fits into the concave step 106 of the opening 103. As a result, the connection tool 102 is fixed to the fixing tool 101, and the valve body 120 of the on-off valve 118 is pressed by the front end portion of the differential port 103 so that the on-off valve 118 is opened. .

  On the other hand, when removing the connecting tool 102 from the fixing tool 101, if the outer cylinder 112 is slid forward against the biasing force of the coil spring 124, the pressing holding state of the claw 127 by the pressing convex portion 130 of the outer cylinder 112 is changed. It will be released. Therefore, when the connection tool 102 is pulled out from the fixing tool 101 in this state, the claw 127 receives an outward pressing force from the gap 103 and moves back into the hole 129, and the concave step 106 of the claw 127 and the gap 103. Therefore, the connection tool 102 can be detached from the fixing tool 101. In this way, the attachment / detachment of the fixture 101 and the connector 102 can be performed very easily and reliably by a so-called one-touch operation.

  Next, water supply from the water supply source is started. As shown in FIG. 9, the float 37 before water supply is lowered by its own weight, and the connecting arm 84 is connected via a connecting rod 92 provided on the float 37. Is in a state of rotating so that its front end portion is inclined downward. And since the valve body 88 provided in the base part 86 of the connection arm 84 and the convex-shaped part 81 of the cover body 70 are separated, the communicating hole 80 is in an open state. Accordingly, the diaphragm valve 74 of the ball tap 2 is bent rearward by receiving the water pressure of the working water flowing into the ball tap main body 20 through the hose H and the connection joint 3, and the inflow hole 52 and the outflow hole 54 of the valve seat 53 are opened. Is done. As a result, the used water is supplied from the square hole 35 of the outflow pipe 34 to the water storage container 1 through the outlet 32 of the ball tap body 20.

  Thereafter, when the water level of the water storage container 1 reaches the position of the float 37, the float 37 rises along the outflow pipe 34 while receiving buoyancy. Accordingly, as shown in FIG. 7, the connecting arm 84 is gradually rotated through the connecting rod 92 so that the front end thereof is raised, and the communication hole 80 of the lid 70 is provided by the valve body 88 provided on the base 86. Is closed and the rise of the float 37 is stopped (see FIG. 2).

  When the communication hole 80 is closed by the valve body 88 in this way, a part of the used water flows into the back pressure chamber 76 through the communication groove 73 formed in the guide pin 72 of the lid body 70. The pressure inside the back pressure chamber 76 is increased, and the pressing force in the valve closing direction (forward direction) with respect to the diaphragm valve 74 is increased. Then, when the pressing force exceeds the water pressure of the working water, the diaphragm valve 74 is seated on the valve seat 53 and the inflow hole 52 and the outflow hole 54 are closed. Thereby, it becomes the predetermined water level of the water storage container 1, and water supply will be stopped automatically.

  When using the water stored in the water storage container 1 to clean walls, floors, and various vehicles with a high pressure washer, for example, the high pressure washer is set in the water container 1 with the high pressure cleaning water absorption hose set. It starts and cleans by injecting use water into the wall surface etc. from the nozzle at high pressure.

  When the water level of the water storage container 1 is lowered due to the use of the water stored by such a cleaning operation, the valve of the connecting arm 84 is again driven by the downward movement of the connecting rod 92 and the rotation of the connecting arm 84 in conjunction therewith. The body 88 separates from the convex portion 81 of the lid 70, and water supply to the water storage container 1 is automatically started in the same manner as described above.

  As described above, the water storage unit according to the present embodiment includes the ball tap 2 that can appropriately supply and stop the water supply according to the water level of the water storage container 1, and therefore, the water storage unit 1 is unfair from the water storage container 1. As well as being able to avoid overflowing well, the burden on the water supply management of the worker is greatly reduced, so that the worker can concentrate on the original work, resulting in greatly improved work efficiency. Can be improved.

  Further, since the float 37 is configured to move up and down along the outflow pipe 34 provided downward in the lower portion of the ball tap body 20, that is, the float 37 is disposed at a position below the ball tap body 20. For this reason, it becomes possible to secure a sufficient space in the water storage container 1. Therefore, in order to use the used water stored in the water storage container 1, for example, a water absorption hose having a relatively large strainer is set in the water storage container 1, or a large submersible pump is set. However, the situation that the float 37 interferes with the installation can be avoided, and the usability is very good.

  Moreover, since the up-and-down raising / lowering range of the float 37 can be arbitrarily adjusted by rotating the connecting rod 92, the water level at which the water supply to the water storage container 1 is started and the water level at which the water supply is stopped are appropriately changed. It is possible. Thereby, the appropriate water storage management according to the kind of operation which uses water storage, a use aspect, etc. can be performed.

  In addition, since the overall structure of the water storage unit according to the present embodiment is very simple, the water storage unit is extremely easy to handle and has practical advantages that it can be manufactured at low cost.

  In addition, although the water storage container 1 in the said embodiment is comprised with the bucket made from a synthetic resin, the water storage container 1 in this invention is not limited to this at all. The material, capacity, etc. can be changed as appropriate.

  Further, the water storage container 1 is not necessarily provided with the handle 11 as in the above embodiment, and may be omitted.

  Moreover, in the said embodiment, although the ball tap 2 was mentioned and demonstrated as an example of a float valve, the float valve in this invention is not limited to this.

  In addition, specific configurations such as the shapes of the ball tap 2 and the connection joint 3 are not questioned at all, and the design can be arbitrarily changed within the intended range of the present invention.
