  According to the present invention, it is possible to attach a water faucet to a water outlet of a conventional hot water supply and water supply mixer tap, and to attach various removable oral cleaning tools directly to the water faucet attachment port. It is possible to realize a removable oral cleaning tool that can easily adjust the temperature, pressure, etc. without the need, and the widespread use of the faucet having this attachment port enables the widespread use of the oral cleaning device. With the increase in the number of consumers, demand for many types of desorption oral cleaning devices and oral cleaning tools ranging from inexpensive products to high-end products can be expected.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the following embodiments will be described with reference to the accompanying drawings as the best mode for carrying out a faucet for attaching an oral cleaning tool and a removable oral cleaning tool of the present invention.

  FIG. 1 is an explanatory view showing a center set type two-handle mixing plug 1 as an example of the present invention. A mouth faucet attachment faucet 10 is screwed to the tip spout 2 of the faucet pipe 5 of the two-handle mixer tap 1 via an attachment portion having a diameter that matches the specifications of the spout. When the two-handle mixer tap 1 is used as a normal hot and cold water mixer tap, the switching lever 14 of the faucet 10 for attaching the mouth washer is on the side of the spout water channel 16 (FIG. 2 (a)) so that the mouth can be cleaned. Since the fixture attachment port 12 (FIG. 2A) side is closed, hot water whose temperature is adjusted by the hot water supply handle 3 and the water supply handle 4 is distributed from the water discharge port 6. In the following description, the two-handle mixer tap 1 will be described as an example, but the oral cleaning tool mounting faucet 10 can be screwed to a screw mounting portion of a water discharge port of various hot water mixing plugs such as a single lever system.

  The faucet 10 for attaching an oral cleaning tool is a short cylindrical body having a mounting screw portion 13 corresponding to the inner diameter of the faucet pipe 5 to be mounted at the upper end as shown in FIGS. In addition, a switching lever 14 is attached (FIG. 1). As shown in FIG. 2 (a), the switching lever 14 slides the water channel switching valve 15 incorporated in the faucet 10 for attaching the mouth washer so that the water channel 7 from the water tap pipe 5 is connected to the water outlet channel. It plays a role of switching to the branch water channel 17 on the 16 side and the oral cavity cleaning device attachment port 12 side.

  As shown in FIG. 2 (b), the one-touch joint 30 is connected to the branch water channel 17 in the horizontal direction at the mouth cleaning tool mounting port 12 on the side surface of the mouth cleaning tool mounting faucet 10. This one-touch joint 30 has an internal pressure when the switching lever 14 is switched and the water channel 7 in the mounting faucet 10 is switched to the branch water channel 17 side to the mouth washer attachment port as shown in FIG. The water flow is cut off by a check valve 31 that resists this. And as shown to the same figure (b) and (c), when the end part 24d of the flexible hose 24 of the oral cavity cleaning tool 20 mentioned later is inserted, the branch flow path 17 and the hose end part 24d of the faucet 10 for attachment Can be communicated, and a water flow can be supplied to the body portion 22 operation button 25 on the tip nozzle 23 side of the hose 24 of the oral cleaning tool 20 (). It should be noted that the end 24d of the flexible hose 24 of the oral cleaning tool 20 is dropped even when water pressure is applied while being held by a known locking mechanism (not shown) inside the one-touch joint 30 in the inserted state. However, when removing from the one-touch joint 30, the mechanism (not shown) for holding and locking the hose end 24d inside is released by sliding the attachment / detachment knob 36 of the one-touch joint 30. can do. When the hose 24 of the oral cleaning tool 20 is disconnected, the water channel is again blocked by the check valve 31 in the one-touch joint 30. If the switching lever 14 is returned to its original position at that timing, water is distributed from the water outlet 6 side. In this embodiment, a well-known ball lock system is adopted for the connection between the one-touch joint 30 and the hose end 24d. However, the connection mechanism between the one-touch joint 30 and the hose end is easy to attach and detach. Various connection methods can be adopted as long as the structure can reliably hold the connection against the water pressure at the time of mounting.

  The structure of the one-touch joint 30 will be briefly described. As shown in FIG. 2A, when the hot water is discharged from the spout 6 of the hot and cold water mixing tap 1 and switched to the branch water channel 17 to the oral cleaning device by the switching lever 14, the reverse in the one-touch joint 30 is obtained. The stop valve 31 is closed by the internal pressure of the flowing water flowing into the branch water channel 17. When the flexible hose end portion 24d is inserted into the one-touch joint 30, a lock claw portion as a locking portion that adheres to the side surface of the hose 24 and maintains water tightness to prevent the hose end portion 24d from falling off ( (Not shown) and an O-ring 34 for preventing water leakage are attached. An unlock cylinder 35 is attached to the outer periphery of the one-touch joint 30. The unlocking cylinder 35 is a movable part integrally formed with the outer attachment / detachment knob 36. The hose end 24d is inserted into the one-touch joint 30, and the hose end 24d is held by a lock claw (not shown). In this case, as shown in FIG. 2C, the hose moves to the position of the collar 24c. To remove the hose 24, the desorption knob 36 is pushed toward the attachment port 12 to release the lock, and the hose 24 can be easily detached from the one-touch joint 30.

  FIG. 3 is an explanatory view showing the oral cleaning tool 20 attached to the oral cleaning tool mounting port 12 provided on the side surface of the oral cleaning tool mounting faucet 10 shown in FIG. As shown in the figure, the oral cleaning tool 20 can open and close the main body 22 that also serves as the grip part 21, the tip nozzle 23 that is detachably connected to the tip of the main body 22, and the water channel of the main body 22. An operation button 25 having a push button structure is attached. A flexible hose 24 that supplies cleaning water branched and distributed from the attachment port 12 to the main body 22 and an end 24 b of the flexible hose 24 have a shape that can be inserted and connected to the attachment port 12. In the present embodiment, as shown in FIG. 2, the flexible hose 24 is in a state in which a known pressure-resistant resin hose is rolled into a coil shape by a predetermined length.

  FIG. 4 shows the entire use state in which the one-touch joint 30 of the flexible hose 24 of the oral cleaning tool 20 is attached to the attachment port 12 of the faucet pipe 5 and the cleaning water is ejected from the tip nozzle 23 of the oral cleaning tool 20. It is explanatory drawing. In this embodiment, as shown in the figure, the mouthwash is attached to the one-touch joint 30 of the mouthwashing tool mounting port 12 on the side of the mouthwashing tool mounting faucet 10 screwed into the water outlet at the tip of the faucet pipe 5. The end 24 d (FIG. 3) of the flexible hose 24 of the tool 20 is inserted, and the oral cleaning tool 20 and the water channel of the faucet pipe 5 are in communication with each other via the oral cleaning tool mounting faucet 10. In this state, the amount of water (the amount of hot water) is adjusted by the hot water supply handle 3 and the water supply handle 4, and the operation button 25 of the oral cleaning tool 20 is operated to the open side. It can be ejected from the nozzle 23. At this time, the wash water after the oral cleaning may be discharged to a wash bowl (not shown) and washed away by the wash nozzle 23 or by water distribution from the water discharge port 6 after the water channel is switched.

  As the one-touch joint 30 of the mounting port 12, in addition to the ball lock system described above, various known water-tight and pressure-resistant known quick-touch joints, conventional screw-type and bayonet-type one-touch joints are used. 30 etc. can be used suitably. At this time, it is important that the shape and size of the end 24d of the flexible hose 24 have dimensions common to the inner diameter of the one-touch joint 30 of the mounting faucet. Therefore, it is recommended that these dimensions and shapes be determined as standards standardized by, for example, public organizations and institutions. Thereby, when the faucet 10 for attaching an oral cleaning tool is attached to the faucet of the bathroom at the accommodation, for example, the flexible hose 24 of the oral cleaning tool 20 brought by the guest is connected to the faucet 10 for attaching the oral cleaning tool. Can be used in conjunction with.

  Each figure of FIG. 5 is a partial cross-sectional front view in which a part of the main body 22 of the oral cleaning tool 20 is cut away. In the present embodiment, a push button type operation button 25 is provided on the main body portion 22 of the oral cleaning tool 20, and the cleaning water is ejected from the tip nozzle 23 in a state where the operation button 25 is pressed. ing. Thus, even when the hot water supply handle 3 and the water supply handle 4 are in the open state, the hose end 24d is inserted into the attachment port, and the one-touch joint 30 of the attachment port is in the open state (FIG. 2 (c)). Unless the operation button 25 is pressed, the cleaning water is not ejected, so that it is prevented that the cleaning water is inadvertently ejected from the tip nozzle 23 of the oral cavity cleaning tool 20.

  That is, the operation button 25 is normally closed so that when the water flow from the faucet reaches the oral cleaning device 20, the jet flow does not jump out of the tip nozzle 23 against the user's will. It is preferable to provide a simple flow rate adjustment valve (not shown) that can adjust the pressure. By adopting such a configuration, for example, the user operates the operation button 25 toward the wash bowl in the washroom, thereby ejecting a jet from the tip nozzle 23 and adjusting the pressure and temperature on the water supply side. It can be carried out. In this state, the operation button 25 is once closed, and the operation button 25 is opened while the tip nozzle 23 is placed in the mouth, so that the oral cavity can be washed with washing water at an appropriate temperature and pressure. At this time, the connecting portion of the tip nozzle 23, the flexible hose 24, the connecting portion of the one-touch joint 30, and the like need to be designed to have sufficient pressure resistance performance even when a predetermined water pressure is applied from the hot water supply or water supply side. is there. In addition, if the pressure-resistant design of each part becomes excessive, it will lead to a cost increase and an apparatus must be rugged and large-sized. Therefore, it is preferable to use such a method that avoids stopping the water flow on the main body 22 side of the oral cleaning device 20 for a long time. In this case, the switching lever 14 of the faucet pipe 5 is switched to drain the water from the spout 2. In addition, enforcing the operation procedure for closing the hot water supply handle 3 and the water supply handle 4 leads to a reduction in the load on each member of the oral cleaning tool 20 and a longer life.

  FIG. 5B shows a replacement part for the tip nozzle 23. This tip nozzle 23 is used in the mouth of the user. For this reason, for example, when a large number of people use in the home after breakfast, the flexible hose 24 of the oral cleaning tool 20 is connected to the one-touch joint 30, and, for example, a plurality of tip nozzles 23 with different colors are individually used. Each user may use the tip nozzle 23 of the main body 22 by replacing it with his / her own.

  Further, in this embodiment, as shown in FIG. 5A, the main body portion 22 is provided with a jet pressure switch by a push button 25 and a water pressure adjustment switch 26 that adjusts the water pressure from the tip nozzle 23. Consists of. A part of the water pressure adjusting switch 26 protrudes from the main body 22 and the water pressure can be adjusted by deforming the resin internal hose 27 in which the switch piece 26 can be elastically deformed according to the amount of pressing the part. Further, a water amount adjusting valve (not shown) can be provided in the main body, or a small pump (not shown) that generates an intermittent pulsating water flow or the like can be incorporated. It is also possible to arrange adjustment switches (not shown) for these functions on the grip portion 21 of the main body portion 22 so as to perform hand control when the washing water is ejected. Since such a high-grade oral cleaning tool 20 also includes the end 24d of the flexible hose 24 having the common dimensions described above, the oral cleaning tool 20 carried by the user can be used as an oral cleaning tool such as a hotel at a lodging place. It can be easily connected to the mounting port 12 of the mounting faucet 10 and can be used as its own.

  6 is a low-priced disposable that has a basic performance equivalent to that of the oral cleaning tool 20 shown in FIG. 2 by making the oral cleaning tool 20 shown in FIG. 2 a resin product that can be mass-produced. It is the perspective view which showed one Example made into the product. Such a disposable (disposal) type oral cleaning tool 20 can be provided together with soap or the like as an amenity goods in a toilet of an accommodation facility such as a hotel. Thereby, compared with the case where the toothbrush was provided conventionally, the service which improved the grade can be provided to a guest.

  In the oral cleaning tool 20 shown in FIG. 6, the main body portion 22 also serves as the grip portion 21, and a water amount adjustment knob 28 having a slide structure is attached to a part of the main body portion 22. The water amount adjustment knob 25 has a wedge shape and, when slid in one direction, operates to narrow the diameter of a part 24e of the flexible hose 24 inserted into the main body portion 22 and thereby ejects from the tip nozzle 23. The amount of water to be adjusted can be realized with a simple structure. FIG. 7 is a schematic explanation as another embodiment showing a state in which the opening end 24d of the flexible hose 24 of the oral cleaning tool 20 shown in FIG. 6 is directly attached to the opening provided in a part of the faucet. FIG.
