Description

歯清掃装置Tooth cleaning equipment
　本願発明は、歯に付着したステイン（着色汚れ物質、ヤニ、茶渋等）を除去するのに有効な歯清掃装置に関する。 The present invention relates to a tooth cleaning device that is effective for removing stains (colored stains, stains, tea astringents, etc.) adhering to teeth.
　従来から、特許文献１に示されるように、荷電分子を電気的に歯に引き寄せて、荷電分子を歯の表面に浸透させる方法が知られている。口腔に化膿などの損傷を有しない健康な人の口腔内は、中性から弱酸性である。上記文献に開示の方法によれば、電池のマイナス極を歯ブラシのブラシに接続し、電池のプラス極を歯ブラシの把持部に接続する。そして、フッ素を含む歯磨剤と共に、歯ブラシを使用する。すると、把持部から、手、歯、ブラシへと電流が流れて、マイナスのフッ素イオンが歯中へと電気的に浸透する。これにより、必要量のフッ素イオンが歯中に拡散する。このため、虫歯を予防し、歯の表面の汚れ及び色素を除去し、細菌の繁殖を抑制することができる。よって、口臭を抑えることができ、歯槽膿漏を確実に防止することもできる。 Conventionally, as shown in Patent Document 1, a method is known in which charged molecules are electrically attracted to teeth and the charged molecules penetrate into the tooth surface. The oral cavity of a healthy person who has no damage such as suppuration in the oral cavity is neutral to slightly acidic. According to the method disclosed in the above document, the negative electrode of the battery is connected to the brush of the toothbrush, and the positive electrode of the battery is connected to the holding part of the toothbrush. And a toothbrush is used with the dentifrice containing a fluorine. Then, current flows from the gripping part to the hand, tooth, and brush, and negative fluorine ions are electrically infiltrated into the tooth. As a result, the necessary amount of fluorine ions diffuses into the teeth. For this reason, caries can be prevented, dirt and pigment on the tooth surface can be removed, and bacterial growth can be suppressed. Therefore, bad breath can be suppressed and alveolar pus leakage can also be reliably prevented.
特公昭４８－２７３９０号Japanese Patent Publication No. 48-27390
　しかしながら、上記文献に開示の方法によれば、実際のブラッシング中に、口腔内の唾液が歯磨剤に混入すると共に、ブラッシングにより空気が混入することによって、歯磨剤の成分がステインに作用しにくくなる。また、口腔内で歯磨剤が拡散するため、歯磨剤の成分がステインに作用しにくくなる。また、歯を磨く際にブラシを上下左右に動かすため、電流を一箇所に集中して流すことが困難であり、ステインの除去が不十分になる。また、歯ブラシを手で動かすため、歯ブラシを動かす速さには限界がある。 However, according to the method disclosed in the above document, the saliva in the oral cavity is mixed into the dentifrice during actual brushing, and air is mixed in by brushing, so that the components of the dentifrice are less likely to act on the stain. . Moreover, since the dentifrice diffuses in the oral cavity, the components of the dentifrice are less likely to act on the stain. Further, since the brush is moved up, down, left and right when brushing teeth, it is difficult to concentrate the current in one place, and stain removal becomes insufficient. Moreover, since the toothbrush is moved by hand, there is a limit to the speed at which the toothbrush can be moved.
　本願発明の目的は、電流を集中して流すことができ、歯に付着したステインを効果的に除去することのできる歯清掃装置を提供することにある。 An object of the present invention is to provide a tooth cleaning device that can flow current in a concentrated manner and can effectively remove stains attached to teeth.
　上記の課題を解決するため、本発明の第一の態様によれば、把持部と、洗浄動作部と、内部電源とを備え、洗浄動作部が回動することによって歯を洗浄する歯清掃装置が提供される。把持部には、内部電源の一方の電極に接続されると共に把持部の外面に表出している把持部側電極が設けられている。洗浄動作部には、内部電源の他方の電極に接続された洗浄動作部側電極が設けられている。 In order to solve the above problems, according to a first aspect of the present invention, a tooth cleaning device including a gripping unit, a cleaning operation unit, and an internal power supply, and cleaning teeth by rotating the cleaning operation unit. Is provided. The gripping part is provided with a gripping part side electrode that is connected to one electrode of the internal power supply and exposed on the outer surface of the gripping part. The cleaning operation unit is provided with a cleaning operation unit side electrode connected to the other electrode of the internal power supply.
　この構成によれば、把持部側電極と洗浄動作部側電極との間を人体を介して通電させることで、ステインが洗浄動作部に引き寄せられるため、ステイン除去効果が高められる。例えば、把持部側電極をプラス極とし、洗浄動作部側電極をマイナス極とする。そして、歯磨剤保持部に、ステイン除去に有効な荷電分子となる物質を含む歯磨剤を充填する。この状態で、把持部側電極と洗浄動作部側電極との間を通電させることで、電流が、装置を把持する手から人の身体に流れ、最終的には人の歯へと流れる。その後、電流は、歯磨剤保持部の歯磨剤を介して洗浄動作部側電極へと流れる。このとき、マイナス電荷を有する荷電分子は、プラス電極側である歯へ引き寄せられ、歯近傍の荷電分子濃度が高くなる。その結果、歯に付着したステインに作用する荷電分子の数が増えるため、ステイン剥離効果を有する化学反応が促進されて、ステイン除去効果が高められる。 According to this configuration, since the stain is attracted to the cleaning operation portion by energizing the grip portion side electrode and the cleaning operation portion side electrode through the human body, the stain removing effect is enhanced. For example, the gripping part side electrode is a positive electrode and the cleaning operation part side electrode is a negative electrode. Then, the dentifrice holder is filled with a dentifrice containing a substance that becomes a charged molecule effective for stain removal. In this state, by energizing between the gripping part side electrode and the cleaning operation part side electrode, a current flows from the hand holding the device to the human body and finally to the human tooth. Thereafter, the current flows to the cleaning operation unit side electrode through the dentifrice of the dentifrice holder. At this time, charged molecules having negative charges are attracted to the teeth on the positive electrode side, and the concentration of charged molecules near the teeth increases. As a result, since the number of charged molecules acting on the stain attached to the teeth increases, a chemical reaction having a stain peeling effect is promoted, and the stain removal effect is enhanced.
　また、洗浄動作部に洗浄動作部側電極が設けられているため、歯と洗浄動作部側電極との距離が近くなる。これにより、人体を介した通電が容易に行えるため、ステインが洗浄動作部に引き寄せられ易くなり、ステイン除去効果が促進される。更に、洗浄動作部を一箇所に固定したままで歯を磨くことができ、一箇所に集中して電流を流すこともできる。こうしてステイン除去効果が高められた状態で、洗浄動作部を回動させて歯を磨くことにより、ステイン除去効果がより一層促進される。また、手動の装置と比べて、洗浄動作部をより速く、細かく動かすことができ、清掃効果を高めることもできる。従って、磨く力の弱い子どもやお年寄りでも、簡単にステインを除去することができる。 Also, since the cleaning operation unit side electrode is provided in the cleaning operation unit, the distance between the teeth and the cleaning operation unit side electrode is reduced. Thereby, since electricity can be easily passed through the human body, the stain is easily attracted to the cleaning operation unit, and the stain removal effect is promoted. Further, the teeth can be brushed while the cleaning operation unit is fixed at one place, and the current can be concentrated in one place. In this state, the stain removal effect is further enhanced by rotating the cleaning operation unit to brush the teeth. Moreover, compared with a manual apparatus, a washing | cleaning operation | movement part can be moved more quickly and finely, and the cleaning effect can also be heightened. Therefore, even stain-free children and the elderly can easily remove stains.
　また、この場合、口腔内の唾液や水等に含まれるステイン（着色汚れ物質、ヤニ、茶渋等）が洗浄動作部側電極に引き寄せられるため、ステイン除去効果を高めるのに有効である。また、歯磨剤が荷電分子配合剤ではない場合であっても、歯がプラス極となり、洗浄動作部側電極がマイナス極となるため、口腔内の唾液や水等に含まれるステインが洗浄動作部側電極に引き寄せられる。よって、ステイン除去効果を高めるのに有効である。また、従来の装置よりも、洗浄動作部側電極と歯との距離を近くできるため、人体を介した通電が一層容易に行えるようになる。その結果、荷電分子がステインに作用し易くなり、ステイン除去効果がより一層促進される。 Further, in this case, stains (colored dirt substances, spears, tea astringents, etc.) contained in the saliva or water in the oral cavity are attracted to the cleaning operation part side electrode, which is effective in enhancing the stain removal effect. In addition, even if the dentifrice is not a charged molecule compounding agent, the teeth become a positive electrode and the cleaning operation part side electrode becomes a negative electrode, so that stains contained in saliva or water in the oral cavity are in the cleaning operation part. It is attracted to the side electrode. Therefore, it is effective for enhancing the stain removal effect. In addition, since the distance between the cleaning operation unit side electrode and the teeth can be made shorter than in the conventional apparatus, it is possible to more easily energize through the human body. As a result, the charged molecules easily act on the stain, and the stain removal effect is further promoted.

In said tooth cleaning apparatus, it is preferable that the brushing part is provided with the dentifrice holding | maintenance part for hold | maintaining dentifrice.
　この構成によれば、歯磨剤を保持するための歯磨剤保持部によって、口腔内に歯磨剤が分散することを防ぎ、電流を集中して流すことができる。このため、ステインを除去する荷電分子が歯へ引き寄せられる数を増やすことができ、ステイン除去効果が一層高められる。
また、空気や唾液の歯磨剤への混入を防ぐこともできる。よって、歯磨剤の濃度が薄くならず、ステイン除去効果がより一層高められる。 According to this configuration, the dentifrice holder for holding the dentifrice can prevent the dentifrice from being dispersed in the oral cavity, and the current can be concentrated. For this reason, it is possible to increase the number of charged molecules that remove stain to the teeth, and the stain removal effect is further enhanced.
Moreover, mixing of air and saliva into the dentifrice can also be prevented. Therefore, the concentration of the dentifrice is not reduced, and the stain removal effect is further enhanced.
　上記の歯清掃装置において、歯磨剤保持部は、洗浄動作部側電極の先端に設けられていることが好ましい。
　この構成によれば、歯磨剤保持部に歯磨剤を配置することによって、電流を集中して流すことができる。このため、荷電分子を効率的に移動させて、ステインを集中的に除去することができる。また、歯磨剤保持部によって、歯磨剤を保持しつつ、放出することもできる。このため、電流を歯磨剤に流しながら、歯を磨くことができ、ステイン除去効果がより一層高められる。 In said tooth cleaning apparatus, it is preferable that the dentifrice holding | maintenance part is provided in the front-end | tip of the washing | cleaning operation part side electrode.

　操作スイッチ１４を回して内部電源４を入れると、内部電源４から回路１７に電流が流れて、回路運動駆動用のモーター１５が駆動し、運動変換部１８が回転する。これにより、往復駆動体１９が往復直線運動すると共に、スライドシャフト２０も往復直線運動する。そして、スライドシャフト２０の往復直線運動が、洗浄動作部側電極６の偏心軸２４と連結片２５とを介して洗浄動作部側電極６へと伝達される。これにより、洗浄動作部側電極６が往復回動運動し、洗浄動作部２の全体が往復回動運動する。 When the operation switch 14 is turned to turn on the internal power supply 4, a current flows from the internal power supply 4 to the circuit 17, the circuit motion driving motor 15 is driven, and the motion conversion unit 18 rotates. Thereby, the reciprocating drive body 19 reciprocates linearly, and the slide shaft 20 also reciprocates linearly. The reciprocating linear motion of the slide shaft 20 is transmitted to the cleaning operation unit side electrode 6 via the eccentric shaft 24 of the cleaning operation unit side electrode 6 and the connecting piece 25. As a result, the cleaning operation unit side electrode 6 reciprocally rotates, and the entire cleaning operation unit 2 reciprocates.
　このとき、把持部側電極５をプラス極とし洗浄動作部側電極６をマイナス極とした導通経路が形成される。電流は、把持部１から、把持部１を持つ手を介して人の身体に流れ、最終的には人の歯へと流れる。その後、電流は、歯から歯磨剤を介して洗浄動作部側電極６へと流れる。そして、電流は、洗浄動作部側電極６から、金属製の偏心軸２４、スライドシャフト２０、往復駆動接合部２１、往復駆動体１９、運動変換部１８に流れ、最終的には把持部側電極５へと戻る。 At this time, a conduction path is formed with the gripping part side electrode 5 as a positive pole and the cleaning operation part side electrode 6 as a negative pole. The electric current flows from the grip portion 1 to the human body through the hand having the grip portion 1 and finally flows to the human teeth. Thereafter, the current flows from the teeth to the cleaning operation part side electrode 6 through the dentifrice. The current flows from the cleaning operation unit side electrode 6 to the metal eccentric shaft 24, the slide shaft 20, the reciprocating drive joint unit 21, the reciprocating drive unit 19, and the motion conversion unit 18, and finally the grip unit side electrode. Return to 5.
　アタッチメント部１０を本体部１１に対し着脱する際、アタッチメント部１０のスライドシャフト２０は、往復駆動接合部２１を介して、本体部１１内の往復駆動体１９に対し着脱される。このため、本体部１１とアタッチメント部１０との接続部１２には、パッキンなどからなる水浸入防止部材１３が装着されている。水浸入防止部材１３は、装置内への水の浸入を防止すると共に、漏電を防止して使用者の安全性を確保する。 When attaching / detaching the attachment part 10 to / from the main body part 11, the slide shaft 20 of the attachment part 10 is attached / detached to / from the reciprocating drive body 19 in the main body part 11 via the reciprocating drive joint part 21. For this reason, a water intrusion prevention member 13 made of packing or the like is attached to the connection portion 12 between the main body portion 11 and the attachment portion 10. The water intrusion prevention member 13 prevents the intrusion of water into the apparatus and prevents electric leakage to ensure the safety of the user.
　第１実施形態によれば、以下の効果を奏することができる。
　（１）把持部側電極５と洗浄動作部側電極６との間を人体を介して通電させることで、ステインが洗浄動作部２に引き寄せられるため、ステイン除去効果が高められる。例えば、把持部側電極５をプラス極とし、洗浄動作部側電極６をマイナス極とする。そして、歯磨剤保持部７に、マイナス電荷を帯びた荷電分子（例えば、ピロリン酸ナトリウム）を含む歯磨剤を充填する。この状態で、把持部側電極５と洗浄動作部側電極６との間を通電させながら歯を磨くことにより、マイナス電荷を帯びた荷電分子が歯に引き寄せられる。その結果、歯に付着したステインに作用する荷電分子の数が増えるため、ステイン剥離効果を有する化学反応が促進されて、ステイン除去効果が高められる。なお、フッ素含有の歯磨剤などを使用しても、上記と同様の効果が得られる。 According to the first embodiment, the following effects can be achieved.
(1) Since the stain is attracted to the cleaning operation unit 2 by energizing between the gripping unit side electrode 5 and the cleaning operation unit side electrode 6 through the human body, the stain removing effect is enhanced. For example, the gripping part side electrode 5 is a positive electrode and the cleaning operation part side electrode 6 is a negative electrode. Then, the dentifrice holder 7 is filled with a dentifrice containing negatively charged charged molecules (for example, sodium pyrophosphate). In this state, by brushing the teeth while energizing between the grip part side electrode 5 and the cleaning operation part side electrode 6, charged molecules having a negative charge are attracted to the teeth. As a result, since the number of charged molecules acting on the stain attached to the teeth increases, a chemical reaction having a stain peeling effect is promoted, and the stain removal effect is enhanced. In addition, even if it uses a fluorine-containing dentifrice etc., the effect similar to the above is acquired.
　また、洗浄動作部２に洗浄動作部側電極６が設けられているため、歯と洗浄動作部側電極６との距離が近くなる。これにより、人体を介した通電が容易に行えるため、ステインが洗浄動作部２に引き寄せられ易くなり、ステイン除去効果が促進される。即ち、荷電分子を動かす力をＦ、電荷をＱ、電界をＥとすると、Ｆ＝Ｑ×Ｅの関係が成立し、電圧をＶ、距離をｄとすると、Ｅ＝Ｖ／ｄ（Ｖ＝ｄＥより）の関係が成立する。つまり、洗浄動作部側電極６と歯との距離が近いほど、荷電分子を動かす力が大きくなり、荷電分子が歯に引き寄せられ易くなる。その結果、荷電分子がステインに作用し易くなり、ステイン除去効果が高められる。 Further, since the cleaning operation unit side electrode 6 is provided in the cleaning operation unit 2, the distance between the teeth and the cleaning operation unit side electrode 6 is reduced. As a result, energization through the human body can be easily performed, so that the stain is easily attracted to the cleaning operation unit 2 and the stain removal effect is promoted. That is, if the force to move the charged molecule is F, the charge is Q, and the electric field is E, the relationship F = Q × E is established. If the voltage is V and the distance is d, E = V / d (V = dE The relationship of () is established. That is, as the distance between the cleaning operation unit side electrode 6 and the tooth is shorter, the force for moving the charged molecule is increased, and the charged molecule is easily attracted to the tooth. As a result, charged molecules easily act on the stain, and the stain removal effect is enhanced.
　更に、洗浄動作部２を一箇所に固定したままで歯を磨くことができ、一箇所に集中して電流を流すこともできる。こうしてステイン除去効果が高められた状態で、洗浄動作部２を往復回動させて歯を磨くことにより、ステイン除去効果がより一層促進される。また、手動の装置と比べて、洗浄動作部２をより速く、細かく動かすことができ、清掃効果を高めることもできる。従って、磨く力の弱い子どもやお年寄りでも、簡単にステインを除去することができる。 Furthermore, the teeth can be brushed while the cleaning operation unit 2 is fixed at one place, and the current can be concentrated in one place. In this state, the stain removal effect is further promoted by brushing the teeth by reciprocating the cleaning operation unit 2 in a state where the stain removal effect is enhanced. Moreover, compared with a manual apparatus, the washing | cleaning operation | movement part 2 can be moved faster and finely, and the cleaning effect can also be heightened. Therefore, even stain-free children and the elderly can easily remove stains.
　また、この場合、口腔内の唾液や水等に含まれるステイン着色汚れ物質、ヤニ、茶渋等が洗浄動作部側電極６に引き寄せられるため、ステイン除去効果を高めるのに有効である。使用者は、この状態で洗浄動作部２を歯や歯茎に当てることにより、口腔内の清掃、特に、歯に着色した汚れを除去することができる。また、従来の装置に比べて、歯間部や歯凹面等の細溝に付着したステインに荷電分子を運び易くすることもできる。同時に、プラス荷電を持つ着色物質を、歯の表面及び口腔内唾液からマイナス極の電極に引き寄せることもできる。よって、汚れ成分が歯に定着することを防ぐこともできる。 Also, in this case, stain-stained dirt substances, spears, tea astringents, etc. contained in saliva or water in the oral cavity are attracted to the cleaning operation part side electrode 6, which is effective in enhancing the stain removal effect. The user can clean the inside of the oral cavity, particularly remove stains on the teeth, by applying the cleaning operation unit 2 to the teeth and gums in this state. In addition, it is possible to make it easier to carry charged molecules to stains attached to narrow grooves such as interdental portions and dented surfaces as compared with conventional devices. At the same time, a colored substance having a positive charge can be attracted from the tooth surface and oral saliva to the negative electrode. Therefore, it is possible to prevent the dirt component from fixing to the teeth.
　また、本願発明によれば、洗浄動作部側電極６が回動部としても機能するため、装置を構成する部品の数を減らすこともできる。よって、エネルギーロスを減らすこともでき、歯清掃装置３の軽量化を図ることもできる。荷電分子としては、Ｍｎ＋２ＰｎＯ３ｎ＋１で示される直鎖状の水溶性ポリリン酸等が挙げられ、特に重合度ｎ＝２となるピロリン酸ナトリウムＮａ４Ｐ２Ｏ７が好ましい。 Moreover, according to this invention, since the washing | cleaning operation part side electrode 6 functions also as a rotation part, the number of components which comprise an apparatus can also be reduced. Therefore, energy loss can also be reduced and weight reduction of the tooth cleaning apparatus 3 can also be achieved. The charged molecules, such as linear water-soluble polyphosphoric acid. Represented by M n + 2 P n O 3n + 1, in particular the degree of polymerization n = 2 to become sodium pyrophosphate Na 4 P 2 O 7 is preferred.
　（２）歯磨剤保持部７に歯磨剤を配置することによって、口腔内に歯磨剤が分散することを防ぎ、電流を集中して流すことができる。このため、荷電分子を効率的に移動させることができ、ステインを集中的に除去することができる。また、歯磨剤保持部７によって、歯磨剤を保持しつつ、放出することもできる。このため、電流を歯磨剤に流しながら、歯を磨くことができ、ステイン除去効果がより一層高められる。また、空気や唾液の歯磨剤への混入を防ぐこともできる。よって、歯磨剤の濃度が薄くならず、ステイン除去効果がより一層高められる。 (2) By disposing the dentifrice in the dentifrice holder 7, it is possible to prevent the dentifrice from being dispersed in the oral cavity, and to concentrate the current. For this reason, a charged molecule can be moved efficiently and stain can be removed intensively. Further, the dentifrice holder 7 can also release the dentifrice while holding it. For this reason, it is possible to brush the teeth while passing an electric current through the dentifrice, and the stain removal effect is further enhanced. Moreover, mixing of air and saliva into the dentifrice can also be prevented. Therefore, the concentration of the dentifrice is not reduced, and the stain removal effect is further enhanced.
　（３）洗浄動作部２は往復回動運動をする。このため、洗浄動作部２が回転運動をする従来の歯清掃装置と比べて、歯磨剤の分散を防ぐことができる。
　（４）外枠部８は、カップ状に形成されている。このため、通常の歯ブラシに比べ、ステインに対してシリカ等の研磨剤粒子を確実に接触させることができる。これにより、研磨剤による高い刷掃力が得られるため、ステイン層が削られ易くなり、ステイン層には隙間が形成される。例えば、荷電分子としてピロリン酸ナトリウムを含む歯磨剤を用いる場合、ステイン層に形成された隙間を通って、ステイン除去成分が唾液たんぱく層に到達し易くなる。これにより、唾液たんぱく層に到達するステイン除去成分が増加するため、ステイン除去効果が高められる。 (3) The cleaning operation unit 2 reciprocates. For this reason, compared with the conventional tooth cleaning apparatus with which the washing | cleaning operation | movement part 2 rotates, dispersion | distribution of dentifrice can be prevented.
(4) The outer frame portion 8 is formed in a cup shape. For this reason, compared with a normal toothbrush, abrasive particles, such as a silica, can be reliably made to contact with stain. As a result, a high brushing force by the abrasive is obtained, so that the stain layer is easily scraped, and a gap is formed in the stain layer. For example, when a dentifrice containing sodium pyrophosphate as a charged molecule is used, the stain removing component easily reaches the saliva protein layer through the gap formed in the stain layer. Thereby, since the stain removal component which reaches | attains a saliva protein layer increases, the stain removal effect is heightened.
　（５）歯磨剤保持部７の底部が、洗浄動作部側電極６と接している。このため、歯磨剤に電流を確実に流すことができる。よって、歯磨剤に電流を流しながら歯を清掃することができ、ステイン除去効果がより一層高められる。 (5) The bottom part of the dentifrice holding part 7 is in contact with the cleaning operation part side electrode 6. For this reason, an electric current can be reliably sent through a dentifrice. Therefore, teeth can be cleaned while passing an electric current through the dentifrice, and the stain removal effect is further enhanced.
　（６）歯磨剤保持部７は電気絶縁材料からなる。このため、洗浄動作部側電極６と口腔内の皮膚や歯との直接的な接触を防ぐことができ、使用者の安全を確保することができる。 (6) The dentifrice holder 7 is made of an electrically insulating material. For this reason, the direct contact between the cleaning operation unit side electrode 6 and the skin or teeth in the oral cavity can be prevented, and the safety of the user can be ensured.
　（７）アタッチメント部１０と本体部１１とが分割可能であるため、コンパクトになり、持ち運びが容易に行える。また、水浸入防止部材１３によって、装置内への水の浸入を防ぐことができ、装置内内の部品の劣化を防ぐこともできる。よって、装置の寿命が長くなる。また、漏電も防止されるため、使用者の安全を確保することもできる。更に、使用者の好みに応じて、洗浄動作部２を付け替えて使用することもできる。つまり、１つの本体部１１に対して、複数種類のアタッチメント部１０を交換して取り付けることができる。このため、家族で本体部１１を共有することができる。
［第２実施形態］
　以下、本発明の歯清掃装置を具体化した第２実施形態を図６～図８を参照して説明する。なお、第２実施形態における第１実施形態と同様の部分についてはその詳細な説明を省略する。 (7) Since the attachment part 10 and the main body part 11 can be divided, it is compact and can be easily carried. Further, the water intrusion prevention member 13 can prevent water from entering the apparatus, and can also prevent deterioration of components in the apparatus. Therefore, the lifetime of the device is extended. Moreover, since leakage is prevented, the safety of the user can be ensured. Furthermore, the cleaning operation unit 2 can be replaced and used according to the user's preference. That is, a plurality of types of attachment parts 10 can be exchanged and attached to one main body part 11. For this reason, the main body part 11 can be shared by the family.
