[0003] [Patent Document 1] JP 2000-157563 A [Patent Document 2] Utility Model Registration No. 3153720 Summary of the Invention [Problem to be solved by the invention]

[0004] For example, the invention described in Patent Document 1 is a cleaning tool that cleans the inside of the mouth by changing the direction of the water flow and generating a single rotating water flow.

[0005] However, this invention has a complex structure for generating the water flow, and each part cannot be detached, making cleaning difficult.

[0006] Moreover, the invention of Patent Document 2 simplifies the structure by using a manual pump.

[0007] However, this device has low water pressure, making it difficult to clean the residue trapped in the gaps between teeth or between the dentures and gums. [Means for solving the problem]

[0008] In order to solve the above problem, the invention of claim 1 comprises a hose coupling part detachable from a water hose or a shower head adapter part compatible with a shower head, a water conducting main body part detachable from the hose coupling part, and a cleaning water ejection part detachable from the water conducting main body part, wherein the cleaning water ejection part is curved gently or with an angle of 20 degrees to 160 degrees, and the diameter of the hole for ejecting water provided at the other end of the detachable side of the water conducting main body part is 0.5 mm to 3 mm.

[0009] The invention of claim 4 is the oral cleaning device of claim 1, characterized in that the cleaning water ejection section is provided with a medicinal liquid injection port section having a diameter of 0.5 mm to 3 mm for the purpose of injecting medicinal liquid into the water flow. Effect of the Invention

[0010] According to the invention of claim 1, it is possible to provide a cleaning tool that can clean the mouth while maintaining a free water pressure, has a simple structure, and is easy to clean. In addition, it can be connected to a water faucet that is connected to hot water, or a commercially available shower head adapter, so it is easy to introduce hot water when used in winter.

[0011] According to the invention of claim 4, oral cavity cleaning can be performed while a medicinal liquid for preventing gingivitis or the like is being further injected. [Brief description of the drawings]

[0027] The flush water ejection fitting 121 is provided for connecting the flush water ejection part 13 and the water guide main body part 12. As shown in the figure, a screw groove may be provided for engagement, or a butt joint structure may be used.

[0028] The water-conducting main body pipe portion 122 is a pipe that sends the water flowing in from the hose joint portion 11 to the water-conducting main body portion 12. The diameter may be gradually reduced toward the wash water injection fitting portion 121 so as to match the diameter of the wash water injection portion 13, or may be the same diameter as in a cylindrical shape, and is preferably 300 mm to 400 mm.

[0029] The hose fitting connection part 123 is a part that is connected to the hose fitting part 11. The hose fitting connection part 123 is preferably of the same size as the diameter of the water guide main body fitting part 111. When the hose fitting part 11 and the water guide main body part 12 are integrated and connected in advance, the hose fitting connection part 123 may not be provided.

[0030] The anti-slip portion 124 is provided in the center of the water conducting main body 12, and is a portion that is made of a material or processed to increase friction so that the hand does not slip when gripped by the hand. It may be provided with fine mesh-like grooves, or may be wrapped with thin silicon or rubber. The anti-slip portion 124 does not have to be provided in particular.

[0031] As shown in Figure 4, the cleaning water ejection section 13 that forms the oral cleaning device 1 is a section that ejects ejected water W for cleaning the teeth, and includes a water-conducting main body connection section 131, a cleaning water ejection tube section 132, a cleaning water ejection blowing section 133, and a medicinal liquid injection section 134.

[0032] The water conducting main body connecting portion 131 is a fitting portion between the wash water ejection portion 13 and the water conducting main body portion 12. The water conducting main body connecting portion 131 is preferably of the same size as the diameter of the wash water ejection fitting portion 121.

[0033] The cleansing water ejection pipe section 132 is a pipe that sends the water flowing in from the water-conducting main body section 12 to the cleansing water ejection blowout section 133. As shown in Fig. 9, the cleansing water ejection pipe section 132 is curved gently or with an angle, and the cleansing water ejection pipe bending angle R is 20 degrees to 160 degrees. Also, as shown in Fig. 2, the cleansing water ejection pipe section 132 may be straight without being curved.

The diameter of the wash water ejection part 133 is 0.5 mm to 3 mm in order to maintain water pressure. The length of the wash water ejection part 133 is between 50 mm to 100 mm, and preferably 70 mm.

[0035] 8, the purpose of the medicinal liquid injection part 134 is to inject medicinal liquid K for preventing gingivitis and the like into the ejected water W. The medicinal liquid injection part 134 preferably has a diameter of 1 mm to 3 mm so that a tube or the like for the medicinal liquid K can be inserted, but the medicinal liquid injection part 134 does not necessarily have to be provided. When the medicinal liquid injection part 134 is not in use, it is necessary to cover the medicinal liquid injection part 134 with a rubber cap or the like.

[0036] <How to implement> A method for implementing the oral cleansing tool 1 according to an embodiment of the present invention will be described with reference to Figures 10 to 12. Figure 10 is a diagram showing the oral cleansing tool 1 according to an embodiment of the present invention assembled with a hose H connected to a faucet, Figure 11 is Example Figure 1 of the oral cleansing tool 1 according to an embodiment of the present invention, and Figure 12 is Example Figure 2 of the oral cleansing tool 1 according to an embodiment of the present invention.

[0037] As shown in Fig. 10, the oral cleaning tool 1 is connected to a water hose H, which is then connected to a mixer faucet with a cold water faucet FC and a hot water faucet FH. This makes it possible to send hot water when used in winter. The water-conducting main body 12 and the cleaning water ejection part 13 are attached when in use, and it is preferable to have a number of cleaning water ejection parts 13 for the number of people, just like toothbrushes. Also, the faucet outlet FE is directed straight to the side in the direction of the arrow in the figure to avoid getting in the way.

[0038] 11, the oral cleaning tool 1 is grasped with the hand, and water is sent to the water hose H. In order to maintain water pressure and for ease of handling during use, the water hose H is preferably at least 1.5 m long.

[0039] As shown in the figure, the ejected water W ejected from the cleansing water ejection blowout portion 133 of the cleansing water ejection portion 13 is directed toward the oral cavity (teeth) M to clean the inside of the oral cavity (teeth) M.

[0040] After use, as shown in Figure 12, remove the water-conducting main body 12 and flush water ejection part 13 and store them by wrapping them around the mixer faucet FM. By wrapping them around the mixer faucet FM, it becomes possible to use the hose joint part 11 in the attached state on a daily basis without removing it. The hose joint part 11 is always attached using wire B. If wire B is coated with a resin (plastic) film, it can prevent rust. [Explanation of symbols]
