Further, the sustained release cartridge 16 is arranged along the longitudinal direction of the cleaning head 11 having a rectangular planar shape in a state where the tip 15c of the liquid sustained release portion 15 is arranged flush or substantially flush with the bottom surface 17a of the cleaning cushion portion 17. And attached over substantially the entire length excluding both ends. Here, the end portion 15c of the liquid sustained release portion 15 is disposed flush or substantially flush with the bottom surface 17a of the cleaning cushion portion 17 in a no-load state, but the end portion 15c of the liquid sustained release portion 15 is As shown in FIG. 1A, for example, it is preferable that the protruding length s from the bottom surface 17a of the cleaning cushion portion 17 is 0 mm <s and s <2 mm. Since the end portion 15c of the liquid sustained release portion 15 slightly protrudes downward from the bottom surface 17a of the cleaning cushion portion 17, the amount of the liquid agent that is gradually released from the liquid sustained release portion 15 by the pressing force to the cleaning head 11 can be reduced. It becomes possible to adjust. On the other hand, even if a pressing force is applied to the cleaning head 11, the cleaning cushion portion 17 is present around the liquid sustained-release portion 15, so that the liquid sustained-release portion 15 is not crushed excessively, and an appropriate amount of liquid agent is gradually released. Enable.

  Further, the end portion 15c of the liquid sustained release portion 15 can be disposed in a state of being slightly depressed from the bottom surface 17a of the cleaning cushion portion 17 in a no-load state. In this case, when the cleaning cushion portion 17 is compressed by the pressing force to the cleaning head 11, the end portion 15c of the liquid sustained release portion 15 can come into contact with the surface to be cleaned through the cleaning sheet together with the cleaning cushion portion 17. The sustained release cartridge 16 is attached to the cleaning head 11 with the end 15c of the liquid sustained release portion 15 depressed as much as possible.

  The liquid container 14 of the sustained release cartridge 16 may have a negative pressure inside because the stored liquid agent is reduced by the sustained release of the liquid agent via the liquid sustained release part 15. In order to prevent the slow release of the liquid agent from being inhibited by the negative pressure of the liquid storage part 14, the sustained release cartridge 16 employs a hole, a valve, or other configuration as a configuration for replacing the outside air that leads to the liquid storage part 14. To do. These outside air replacement holes and the like are provided in the liquid storage part 14, and depending on the material of the liquid sustained release part 15, the outside air can be taken in through the fine holes of the liquid sustained release part 15. .

And according to the cleaning tool 10 of this embodiment, when cleaning and finishing the surface to be cleaned such as the floor surface, the liquid agent is gradually supplied to the cleaning sheet to stably maintain an appropriate wet state. In addition, the replacement of the liquid agent can be performed by a simple operation, and when the different liquid agent is replaced, it is possible to effectively avoid mixing the liquid agent after replacement with the liquid agent before replacement.

  That is, in the cleaning tool 10 of the present embodiment, the sustained release cartridge 16 including the liquid storage portion 14 and the liquid sustained release portion 15 is attached to the cleaning head 11 by the cartridge engaging means 13 so as to be attachable and detachable. Since the end portion 15c of the liquid sustained release portion 15 contacts the surface to be cleaned together with the lowermost portion of the bottom surface 17a of the cleaning cushion portion 17 by pressing against the cleaning head 11 during cleaning, the liquid sustained release from the liquid storage portion 14 The liquid agent is gradually infiltrated into the portion 15, and it becomes possible to give a moderate humidity to the cleaning surface by the cleaning sheet in a stable state for a predetermined time. Further, since the end 15c of the liquid sustained release portion 15 contacts the surface to be cleaned together with the lowermost portion of the bottom surface 17a of the cleaning cushion portion 17 by pressing against the cleaning head 11 at the time of cleaning, the pressure from the surface to be cleaned at the time of cleaning is increased. The liquid sustained-release part 15 receives the bottom surface 17a of the cleaning cushion part 17, so that excessive pressure is not applied to the liquid sustained-release part 15, and the liquid oozes out more than necessary on the cleaning surface by the cleaning sheet. Can be effectively prevented. Furthermore, by attaching / detaching the sustained release cartridge 16 to / from the cleaning head 11, the liquid agent can be quickly replaced. Furthermore, since the sustained-release cartridge 16 is attached and detached together with the liquid sustained-release part 15, the liquid sustained-release part 15 that adsorbs dirt such as a floor surface or is worn can be easily replaced. Even if the liquid agent is replaced, it is possible to effectively avoid the liquid agent after replacement from being mixed with the liquid agent before replacement in the liquid sustained release portion 15 or the like.

  Further, according to the cleaning tool 10 of the present embodiment, since at least the liquid storage portion 14 of the sustained release cartridge 16 is attached to the cleaning head 11 in a state of being accommodated in the thickness t of the cleaning head 11, The cleaning head 11 can be formed compactly.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, it is not always necessary to attach the sustained release cartridge to the cleaning head in a state where the liquid storage portion is accommodated in the thickness of the cleaning head, and the liquid storage portion may be attached in a state of protruding above the cleaning head. good. Further, the cleaning head is not necessarily provided with a rectangular planar shape, and various modifications such as curving a rectangular short side portion are possible, and the bottom surface of the cleaning head is substantially flat and has a central area. It is possible to adopt a curved shape in which a protrusion protrudes or an uneven shape provided with a plurality of ribs or protrusions.

  And, it is not always necessary to form the sustained release cartridge in a strip shape and attach it linearly as a single one along the longitudinal direction of the cleaning head. They can be arranged in a zigzag manner, or they can be arranged obliquely along the longitudinal direction. Further, the sustained release cartridge can be arranged in the short direction of the cleaning head, can be arranged obliquely, or can be installed in a curved shape. Here, the arrangement along the longitudinal direction means not only an arrangement substantially parallel to the longitudinal direction of the cleaning head, but also the longitudinal direction of the cleaning head with respect to the arranged sustained release cartridge even if it is arranged obliquely with respect to the longitudinal direction. When the longitudinal direction component along the direction is extracted, a relationship that is longer than the lateral direction component along the lateral direction of the cleaning head is included. For example, an arrangement is also included in which a slow release cartridge is disposed obliquely by shifting the joint portion and is formed in a V shape with the joint interposed therebetween.

  Furthermore, as shown in FIGS. 6A and 6B, liquid replenishing tanks 26a and 26b are provided on the handle 12 and the head main body 19 of the cleaning head 11, and attached to the cleaning head 11 via pipes 27a and 27b.
