[0010] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted.

[0011] It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] As shown in FIG. 1, a tank-extending oral cleaning device 1 according to the present embodiment includes a tank 3, a device main body 5, and a nozzle .

[0013] The tank 3 is formed in a cylindrical shape with a bottom. The inside of the tank 3 is a storage section 9 that stores a liquid such as water (hereinafter referred to as water). The device main body 5 is supported in the storage section 9 so as to be slidable in the length direction (hereinafter referred to as the height direction). The device main body 5 is stored in the storage section 9 when the tank-extending oral cleaning device 1 is not in use. When the tank-extending oral cleaning device 1 is in use, the device main body 5 is pulled out from the storage section 9. In this case, water is supplied to the storage section 9 of the tank 3.

[0014] The device body 5 is formed in a cylindrical shape with both ends in the height direction closed. The device body 5 is provided with a tube 11 disposed in the storage section 9 of the tank 3. A filter (not shown) is provided at the tip of the tube 11 for removing foreign matter mixed in the water stored in the storage section 9. The end of the tube 11 on the device body 5 side is connected to a suction passage 13 provided inside the device body 5. The suction passage 13 is connected to a pump 15 built in the device body 5, and supplies the water in the tank 3 sucked up by the tube 11 when the pump 15 is driven to the pump 15.

[0015] The pump 15 includes a motor 17, a cam 19, a piston 21, and a pump chamber 23. The motor 17 is driven by power supplied from a rechargeable battery (not shown) housed inside the device body 5. The cam 19 converts the rotation of the motor 17 into an operating force in the axial direction. The piston 21 is reciprocated along the height direction of the device body 5 by the operating force in the axial direction converted by the cam 19. The pump chamber 23 has an end of the piston 21 disposed therein, and the volume of the pump chamber 23 changes due to the reciprocating motion of the piston 21. The pump chamber 23 is connected to the suction passage 13 and the discharge passage 25 provided inside the device body 5. A suction valve (not shown) is provided between the pump chamber 23 and the suction passage 13, and a discharge valve (not shown) is provided between the pump chamber 23 and the discharge passage 25.

[0016] When the motor 17 is driven to move the piston 21 in a direction that increases the volume of the pump chamber 23, the pump 15 causes the water in the tank 3 to flow into the pump chamber 23 via the tube 11 and the suction passage 13. When the motor 17 is driven to move the piston 21 in a direction that decreases the volume of the pump chamber 23, the water that has flowed into the pump chamber 23 is discharged through the discharge passage 25 to the nozzle 7.

[0017] The nozzle 7 is formed in a hollow, elongated shape and is detachable from the device body 5. When the nozzle 7 is attached to the device body 5, the inside of the nozzle 7 is in communication with the discharge passage 25. The nozzle 7 sprays water flowing out from the discharge passage 25 from the tip.

[0018] When such a tank-type oral cleansing device 1 is not in use, the nozzle 7 is removed from the device body 5, and the device body 5 is pushed into the tank 3 and stored in the tank 3. When the tank-type oral cleansing device 1 is in use, the device body 5 is pulled out from the tank 3, and the nozzle 7 is attached to the device body 5. Details of the tank-type oral cleansing device 1 will be described below with reference to Figs. 1 to 23.

[0019] As shown in Figs. 1 to 12, the device body 5 is formed in a cylindrical shape with both ends in the height direction closed. The device body 5 has a cross-sectional shape formed as a perfect circle so that it can rotate relatively to the tank 3. A nozzle mounting part 27 is provided on the upper surface of the device body 5, in which the nozzle 7 is detachably arranged. An end of the nozzle 7 is inserted into the nozzle mounting part 27, and an engagement part (not shown) provided inside engages with an engaged part (not shown) of the end of the nozzle 7, thereby maintaining the nozzle 7 in an attached state. The nozzle 7 attached to the nozzle mounting part 27 can be removed from the device body 5 by pressing a button 29 provided on the upper side of the device body 5 to release the engagement between the engagement part and the engaged part.

[0020] A power switch 31 for starting or stopping the tank-extending oral cleansing device 1 is provided on the side of the device body 5. A level selection switch 33 for switching the output of the motor 17 of the pump 15 and switching the strength of water discharged from the nozzle 7 is provided below the power switch 31 on the side of the device body 5. An indicator lamp 35 for displaying the ON / OFF state of the power switch 31 and the selected level of the level selection switch 33 is provided below the level selection switch 33 on the side of the device body 5. A lid 37 for protecting the charging connector of the rechargeable battery built into the device body 5 is provided above and at a different circumferential position from the indicator lamp 35 on the side of the device body 5.

[0021] A tube 11 communicated with the suction passage 13 is integrally attached to the bottom surface of the device body 5. The tube 11 has a length that reaches the bottom of the tank 3 when the device body 5 is pulled out from the tank 3. When the device body 5 is housed in the tank 3, the tube 11 is stored in the tank 3 in a state in which it is wound multiple times. A coil spring 39 that maintains the position of the tube 11 extending in the length direction is arranged around the tube 11. By arranging the coil spring 39, the tube 11 can be wound without bending when the device body 5 is housed in the tank 3, and the tube 11 can be neatly housed in the tank 3. In addition, by arranging the coil spring 39, the tube 11 can be neatly stretched from the wound state when the device body 5 is pulled out from the tank 3.

[0022] A nozzle accommodating section 41 is provided on the side of the device body 5. The nozzle accommodating section 41 is formed in a groove shape capable of accommodating the nozzle 7, and extends along the height direction of the device body 5. The nozzle accommodating section 41 accommodates the nozzle 7 removed from the device body 5. By providing the nozzle accommodating section 41 in the device body 5, the nozzle 7 removed from the device body 5 can be handled together with the device body 5. Therefore, there is no need to manage the nozzle 7 removed from the device body 5 separately from the device body 5, and the nozzle 7 can be easily managed.

[0023] A pull-out protrusion 43 that protrudes from the side surface of the device body 5 is provided below the side surface of the device body 5. The pull-out protrusion 43 extends along the circumferential direction of the device body 5. A plurality of pull-out protrusions 43 (two in this example) are provided in the circumferential direction of the side surface of the device body 5. The pull-out protrusions 43 form a holding portion 45 that holds the device body 5 in the tank 3 when the device body 5 is pulled out of the tank 3.

[0024] Below the pull-out protrusion 43 on the side surface of the device body 5, an accommodating protrusion 47 is provided that protrudes from the side surface of the device body 5. The accommodating protrusion 47 extends along the circumferential direction of the device body 5. A plurality of accommodating protrusions 47 (two in this example) are provided in the circumferential direction on the side surface of the device body 5. The accommodating protrusions 47 form a locking portion 49 that holds the device body 5 in the tank 3 when the device body 5 is accommodated in the tank 3.

[0025] A mark protrusion 51 protruding from the side surface of the device main body 5 is provided at the upper part of the side surface of the device main body 5. The mark protrusion 51 constitutes a mark portion 53 that serves as a guide for positioning the lock portion 49 when the device main body 5 is housed in the tank 3.

[0026] A packing 55 as a sealing member is attached below the device body 5 in close contact with a groove formed continuously in the circumferential direction on the outer circumferential surface of the device body 5. When the device body 5 is attached to the tank 3, the outer circumferential surface of the packing 55 comes into close contact with the inner circumferential surface of the tank 3, sealing the gap between the device body 5 and the tank 3. The packing 55 is detachably attached to the groove of the device body 5, and by removing the packing 55 from the device body 5, only the packing 55 can be cleaned.

[0027] Such device body 5 is slidably supported in the tank 3. When the tank-type oral cleansing device 1 is used, the device body 5 is pulled out from the tank 3. On the other hand, when the tank-type oral cleansing device 1 is not used, the device body 5 is stored in the tank 3.

[0028] As shown in Figs. 1 to 10 and Figs. 13 to 21, the tank 3 is made of polypropylene resin or the like so that it can be washed in a dishwasher, and is made transparent or translucent to enhance the design. The tank 3 is formed in a cylindrical shape with one end in the height direction open and the other end closed, with a bottom. The tank 3 has a cross-sectional shape that is a perfect circle so that the device body 5 can rotate relatively. The inside of the tank 3 is a storage section 9 that stores water. The device body 5 is supported in the storage section 9 so that it can slide in the height direction. The storage section 9 can accommodate the device body 5 except for the upper surface side. The tank 3 includes a cylindrical body 57 and a bottom wall 59.

[0029] The cylindrical body 57 constitutes the peripheral wall of the tank 3, and constitutes most of the storage section 9. An attachment protrusion 61 protruding from the inner peripheral surface of the cylindrical body 57 is provided below the inner peripheral surface of the cylindrical body 57. The attachment protrusion 61 extends along the circumferential direction of the cylindrical body 57. An engagement recess 63 is provided on the outer surface of the attachment protrusion 61. A plurality of attachment protrusions 61 (two in this case) are provided in the circumferential direction of the inner peripheral surface of the cylindrical body 57. The multiple attachment protrusions 61, 61 have different lengths of extension in the circumferential direction of the cylindrical body 57. The attachment protrusions 61 constitute an attachment section 65 that allows the bottom wall 59 to be attached and detached to the cylindrical body 57.

[0030] The bottom wall 59 constitutes the bottom wall of the tank 3 that closes the opening on the lower side of the cylindrical body 57, and constitutes the storage section 9 when attached to the cylindrical body 57. As shown in Figs. 19 to 22, a peripheral wall 67 is provided on the outer periphery of the bottom wall 59, protruding from the bottom surface toward the cylindrical body 57 and continuing in the circumferential direction. The height of the peripheral wall 67 is set so that the user's finger can reach the bottom surface when the bottom wall 59 is removed from the cylindrical body 57. Since the tank 3 is transparent, it is preferable to make the peripheral wall 67 as low as possible so that the boundary line between the cylindrical body 57 and the bottom wall 59 is not noticeable when the bottom wall 59 is attached to the cylindrical body 57.

[0031] As shown in Figs. 15 and 19, a mounting recess 69 is provided on the outer surface of the peripheral wall 67 of the bottom wall 59. The mounting recess 69 is open at the top, and one circumferential side of the peripheral wall 67 is the bottom into which the mounting protrusion 61 is inserted. An engagement protrusion 71 capable of engaging with the engagement recess 63 of the mounting protrusion 61 is formed protruding from the bottom side of the mounting recess 69. An inclined surface 73 that is inclined upward from the bottom to the opening is provided between the opening and the bottom of the mounting recess 69. A plurality of mounting recesses 69 (two in this example) are provided in the circumferential direction of the outer circumferential surface of the peripheral wall 67. The openings of the multiple mounting recesses 69, 69 have different opening lengths in the circumferential direction of the peripheral wall 67. The opening lengths of the openings of the multiple mounting recesses 69, 69 correspond to the extension lengths of the multiple mounting protrusions 61, 61 in the circumferential direction, respectively, so that the multiple mounting protrusions 61, 61 can be inserted. The mounting recess 69 constitutes the mounting projection 61 of the cylindrical body 57 and a mounting portion 65 that enables the bottom wall 59 to be attached to and detached from the cylindrical body 57 .

[0032] When attaching the bottom wall 59 to the cylindrical body 57, first, the corresponding attachment protrusions 61, 61 are placed in the openings of the attachment recesses 69, 69 in the attachment portion 65. Next, the cylindrical body 57 and the bottom wall 59 are moved relatively in a direction approaching each other in the height direction so that the attachment protrusions 61, 61 are inserted into the openings of the attachment recesses 69, 69. Then, with the attachment protrusions 61, 61 inserted into the attachment recesses 69, 69, the cylindrical body 57 and the bottom wall 59 are rotated relatively to insert the attachment protrusions 61, 61 into the bottoms of the attachment recesses 69, 69. At this time, the engagement recesses 63 of the attachment protrusions 61 and the engagement protrusions 71 of the attachment recesses 69 engage with each other, and the attachment state of the bottom wall 59 to the cylindrical body 57 is maintained.

[0033] When removing the bottom wall 59 from the cylindrical body 57, first, the cylindrical body 57 and the bottom wall 59 are rotated relative to each other, and the mounting protrusions 61, 61 are pulled out from the bottom of the mounting recesses 69, 69 in the mounting portion 65. At this time, the engagement between the engagement recesses 63 of the mounting protrusions 61 and the engagement protrusions 71 of the mounting recesses 69 is released. Next, the relative rotation between the cylindrical body 57 and the bottom wall 59 is continued, the mounting protrusions 61, 61 are brought into contact with the inclined surfaces 73, 73 of the mounting recesses 69, 69, and the relative rotation between the cylindrical body 57 and the bottom wall 59 is further continued. At this time, the mounting protrusions 61, 61 slide against the inclined surfaces 73, 73, and the cylindrical body 57 and the bottom wall 59 are moved relatively in the direction of separation in the height direction. The mounting protrusions 61, 61 that have finished sliding against the inclined surfaces 73, 73 are disposed in the openings of the mounting recesses 69, 69. The bottom wall 59 can be removed from the cylindrical body 57 by relatively moving the cylindrical body 57 and the bottom wall 59 in a direction separating them in the height direction.

[0034] Such an attachment portion 65 has a screw structure in which the attachment protrusion 61 and the attachment recess 69 mesh with each other. Therefore, the bottom wall 59 can be attached to and detached from the cylindrical body 57 by rotating the bottom wall 59 around the axis of the cylindrical body 57. In such an attachment portion 65, the multiple attachment protrusions 61, 61 have different circumferential extension lengths. Therefore, the attachment position of the bottom wall 59 relative to the cylindrical body 57 can be positioned at one location in the circumferential direction. Note that, although the attachment position of the bottom wall 59 can be positioned by providing the attachment portion 65 at one location in the circumferential direction, there is a possibility that the bottom wall 59 may become loose relative to the cylindrical body 57. Therefore, it is preferable to provide the attachment portion 65 at multiple locations in the circumferential direction.

[0035] Here, in the conventional tank, the cylindrical body 57 and the bottom wall 59 are formed as a single continuous member. For this reason, in the conventional tank, the bottom wall 59 cannot be removed from the cylindrical body 57, and when cleaning the inner surface of the tank, fingers cannot reach the bottom surface from the opening of the tank, and it is necessary to use a long cleaning brush or the like.

[0036] In contrast, the tank 3 is composed of a cylindrical body 57 and a bottom wall 59 detachably attached to the cylindrical body 57 so that at least a portion of the bottom wall is openable. In such a tank 3, the bottom wall 59 is removed from the cylindrical body 57 when cleaning the inside of the tank 3. When the bottom wall 59 is removed from the cylindrical body 57, the inside bottom surface can be reached with fingers, and there is no need to use a long cleaning brush or the like. This makes it easy to clean the inside bottom surface of the tank 3. In addition, the peripheral wall 67 of the bottom wall 59 is set at a height that allows the bottom surface to be reached with fingers, so that the inside of the tank 3 can be easily cleaned.

[0037] As shown in Figs. 16, 19 to 22, a packing 75 is disposed between the cylindrical body 57 and the bottom wall 59 as a sealing member. The packing 75 is attached in close contact with a groove 77 formed continuously in the circumferential direction on the outer circumferential surface of the peripheral wall 67 of the bottom wall 59. The packing 75 is detachable from the groove 77. A lip is formed continuously in the circumferential direction on the outer circumferential surface of the packing 75, which is in close contact with the inner circumferential surface of the cylindrical body 57. The packing 75 seals between the cylindrical body 57 and the bottom wall 59 by being in close contact with them. The groove 77 may be provided on the inner circumferential surface of the cylindrical body 57.

[0038] In conventional tanks, a sealing member such as packing 75 is formed integrally with the tank, and the sealing member cannot be removed without destroying a part of the tank. In addition, when the sealing member is disposed on the bottom wall side of the tank, it is difficult to clean the sealing member, and dirt such as water stains and mold easily adheres to the sealing member.

[0039] On the other hand, the packing 75 is detachably attached to a groove 77 in the bottom wall 59 which is detachably attached to the cylindrical body 57. Therefore, when removing the packing 75 from the tank 3 for cleaning or the like, the packing 75 can be easily removed from the groove 77 in the bottom wall 59 by removing the bottom wall 59 from the cylindrical body 57. In addition, since the packing 75 can be easily removed from the tank 3, the packing 75 can be easily washed and kept clean.

[0040] 15 and 19, a notch 79 is provided in an upper wall portion constituting groove 77 in which packing 75 is fitted, the notch 79 being cut away from the outer circumferential surface of packing 75. A user can insert his or her finger into notch 79 to allow the finger to come into contact with the outer circumferential surface of packing 75. This allows packing 75 fitted in groove 77 to be easily removed from groove 77. Note that multiple notches 79 may be provided in the circumferential direction of groove 77.

[0041] Here, as a configuration in which at least a part of the bottom wall of the tank 3 is formed to be openable, for example, the tank 3 may be formed of a cylindrical body 57 and a bottom wall 59, and a detachable screw-type mounting part 65 may be provided between the cylindrical body 57 and the bottom wall 59. In this configuration, the bottom wall 59 can be attached to the cylindrical body 57 or the bottom wall 59 can be removed from the cylindrical body 57 by rotating the cylindrical body 57 and the bottom wall 59 relatively. In this configuration, since the cylindrical body 57 and the bottom wall 59 are rotated relatively, at least the screw-type mounting part 65 needs to be formed of a cylinder. In addition, the tank 3 may be formed of a cylindrical body 57 and a bottom wall 59, and the bottom wall 59 may be opened and closed relative to the cylindrical body 57 via the mounting part 65 made of a hinge or the like. Furthermore, the tank 3 may be composed of a cylindrical body 57 and a bottom wall 59, and, for example, the bottom wall 59 may be configured to be detachable from the cylindrical body 57 via an attachment portion 65 consisting of a fitting portion that is fitted by sliding in the vertical direction or the left-right direction.

[0042] As another configuration, for example, the tank 3 is configured as one continuous member including the cylindrical body 57 and the bottom wall 59, an opening is provided in the bottom wall 59 that communicates with the bottom surface inside the bottom wall 59, and a lid is provided to close the opening. In this configuration, it is preferable that the opening in the bottom wall 59 is opened so that a finger can be inserted to clean the entire bottom surface inside the bottom wall 59. It is preferable that the lid that closes the opening can keep the opening closed by, for example, providing the lid on the bottom wall 59 so as to be openable and closable via a hinge, providing an engaging portion at least in one place that can engage with the bottom wall 59, or making the entire lid fitable with the bottom wall 59.

[0043] Here, in the conventional tank, the cylindrical body 57 and the bottom wall 59 are formed as one continuous member, and at least a part of the bottom wall 59 is not opened, so that the water remaining in the tank cannot be discarded when the device body 5 is attached to the tank. For this reason, in the conventional tank, when discarding the water remaining in the tank, it is necessary to remove the device body 5 from the tank. In addition, when removing the device body 5 from the tank, the water remaining in the tank may splash around.

[0044] In contrast, the tank 3 is formed so that at least a portion of the bottom wall can be opened. Therefore, when disposing of the water remaining in the tank 3, the water can be disposed of through the opening, and there is no need to remove the device body 5 from the tank 3. In addition, since the water remaining in the tank 3 can be disposed of without removing the device body 5 from the tank 3, it is possible to prevent the water remaining in the tank 3 from scattering around. Therefore, it is possible to reduce the burden of cleaning the surroundings after use of the tank-extending oral cleaning device 1.

[0045] The device body 5 is supported in such tank 3 so as to be slidable in the height direction. When using the tank-type oral cleansing device 1, the device body 5 is pulled out from the tank 3. The device body 5 is held in the pulled-out state pulled out from the tank 3 by the holding part 45. On the other hand, when use of the tank-type oral cleansing device 1 has finished, the device body 5 is stored in the tank 3. The device body 5 is held in the stored state stored in the tank 3 by the locking part 49.

[0046] 4, 5 and 16, the holding portion 45 includes a pull-out protrusion 43 of the device main body 5 and a pull-out recess 81 provided in the tank 3 that is engageable with the pull-out protrusion 43. The pull-out recess 81 is provided above the inner circumferential surface of the cylindrical body 57 of the tank 3 so as to be engageable with the pull-out protrusion 43 of the device main body 5. The pull-out recess 81 is formed continuously in the circumferential direction of the cylindrical body 57 so as to be engageable with the multiple pull-out protrusions 43, 43.

[0047] When the device body 5 is pulled out from the tank 3, the pull-out protrusion 43 and the pull-out recess 81 of the holding portion 45 engage with each other, and the device body 5 is held in the pull-out position relative to the tank 3. By pulling the device body 5 out of the pull-out position of the tank 3, the engagement of the holding portion 45 is released, and the device body 5 can be removed from the tank 3. In the holding portion 45, the pull-out protrusion 43 is provided at a position overlapping the tank 3 in a front view when the device body 5 is attached to the tank 3. Therefore, when the device body 5 is attached to the tank 3, the pull-out protrusion 43 is not exposed from the tank 3 in a front view, and unnecessary irregularities can be hidden, improving the design.

[0048] As shown in Figs. 6, 7, 20 and 21, the locking portion 49 includes the storage protrusion 47 of the device body 5 and a storage recess 83 provided in the tank 3 that can engage with the storage protrusion 47. The storage recess 83 is provided on the inner circumferential surface of the peripheral wall 67 of the bottom wall 59 of the tank 3 so as to be able to engage with the storage protrusion 47 of the device body 5. The storage recess 83 extends along the circumferential direction of the peripheral wall 67. The circumferential extension length of the storage recess 83 is set to be longer than the circumferential extension length of the storage protrusion 47. A plurality of storage recesses 83 (two in this example) are provided in the circumferential direction of the inner circumferential surface of the peripheral wall 67 so as to be able to engage with the plurality of storage protrusions 47, 47. On both sides of the circumferential direction of the storage recess 83, inclined surfaces 85, 85 that are inclined upward from the bottom are provided, respectively.

[0049] When the device main body 5 is accommodated in the tank 3, the locking portion 49 engages the accommodation protrusion 47 with the accommodation recess 83, and holds the device main body 5 in the accommodation position relative to the tank 3. At this time, the tube 11 is accommodated between the device main body 5 and the tank 3 in a state in which it is wound multiple times, although this is not shown. In addition, a packing 55 is arranged above the accommodation protrusion 47. By arranging the packing 55 above the accommodation protrusion 47, when the device main body 5 is accommodated in the tank 3 or when the device main body 5 is pulled out from the tank 3, the packing 55 does not interfere with the accommodation recess 83, and wear of the packing 55 can be reduced.

[0050] Conventionally, when the device body 5 held by the locking portion 49 is to be pulled out from the tank 3, the device body 5 is gripped and pulled out from the tank 3 to release the engagement of the locking portion 49. However, for example, if water or the like is attached to the device body 5, the device body 5 may slip and the device body 5 may not be able to be pulled out from the tank 3. In such a case, it is difficult to release the engagement of the locking portion 49.

[0051] Therefore, the storage recess 83 of the locking portion 49 is provided with inclined surfaces 85, 85 on both sides in the circumferential direction of the peripheral wall 67, i.e., on both sides in the relative rotation direction of the device body 5 and the tank 3. Therefore, by rotating the device body 5 and the tank 3 relatively, the storage protrusion 47 comes into contact with the inclined surface 85, and the storage protrusion 47 moves while sliding along the inclined surface 85. When the storage protrusion 47 moves along the inclined surface 85, the device body 5 moves upward to come out of the tank 3. When the device body 5 moves upward, the storage protrusion 47 is disengaged from the storage recess 83 in the locking portion 49. When the locking portion 49 is disengaged, the device body 5 can be easily pulled out of the tank 3.

[0052] In such a locking portion 49, even when the device body 5 is slippery, the device body 5 and the tank 3 are rotated relative to each other to easily release the engagement of the locking portion 49. Therefore, the device body 5 can be easily pulled out from the tank 3. In addition, when the engagement of the locking portion 49 is released, the housing protrusion 47 moves along the inclined surface 85, so that the device body 5 is moved in the direction of being pulled out from the tank 3. Therefore, the area for gripping the device body 5 is increased, and the device body 5 can be even more easily pulled out from the tank 3.

[0053] Note that the locking portion that can release the engagement by rotating the device body 5 and the tank 3 relatively may not necessarily have the inclined surfaces 85, 85 on both sides in the circumferential direction of the storage recess 83. In this case, the device body 5 and the tank 3 are rotated relatively to position the engagement protrusion 71 outside the range of the storage recess 83, thereby releasing the engagement of the locking portion. Even with such a locking portion, the device body 5 can be easily pulled out of the tank 3.

[0054] The storage protrusion 47 constituting such a locking portion 49 is provided on the side surface of the device body 5 at a position that overlaps with the tank 3 in a front view when the device body 5 is pulled out from the tank 3. Therefore, as shown in Fig. 2, when the device body 5 is pulled out from the tank 3, the storage protrusion 47 is not exposed from the tank 3 in a front view, making it possible to hide unnecessary irregularities and improve the design.

[0055] Such locking portion 49 is provided on the inside of the tank 3, and even if the tank 3 is formed to be transparent, the engagement and disengagement are difficult to see. Therefore, a mark 53 is provided in a portion visible from the outside of the tank 3, which serves as a guide for the engagement state of the locking portion 49.

[0056] 8 and 9, the marker portion 53 includes a marker protrusion 51 of the device main body 5 and a marker recess 87 provided on the tank 3 that is engageable with the marker protrusion 51. The marker recess 87 is provided on the upper opening edge of the cylindrical body 57 of the tank 3 so as to be engageable with the marker protrusion 51. The marker recess 87 has a bottom portion that engages with the marker protrusion 51, and is provided with inclined surfaces 89, 89 that slope upward from the bottom portion on both sides in the circumferential direction.

[0057] When the mark protrusion 51 of the device main body 5 engages with the bottom of the mark recess 87 of the tank 3, the mark portion 53 indicates that the storage protrusion 47 and the storage recess 83 are engaged in the lock portion 49. Therefore, the user can recognize that the lock portion 49 is engaged by visually checking the engagement between the mark protrusion 51 and the mark recess 87.

[0058] When the device body 5 and the tank 3 are rotated relative to each other, the mark protrusion 51 of the mark portion 53 moves while sliding along the inclined surface 89. When the mark protrusion 51 moves along the inclined surface 89, the device body 5 moves upward to come out of the tank 3. This can assist in disengagement of the locking portion 49. When the mark protrusion 51 finishes moving along the inclined surface 89, the mark protrusion 51 is positioned at the opening edge of the cylindrical body 57, indicating that the engagement between the storage protrusion 47 and the storage recess 83 in the locking portion 49 has been released. Therefore, the user can recognize that the engagement of the locking portion 49 has been released by visually confirming the disengagement between the mark protrusion 51 and the mark recess 87.

[0059] Here, as shown in Figs. 8 and 10, a drying hole 91 penetrating the peripheral wall of the cylindrical body 57 is provided at the upper part of the side surface of the cylindrical body 57 of the tank 3. The drying hole 91 is arranged to face the nozzle housing part 41 of the device body 5 in a state where the device body 5 is housed in the tank 3. By providing the drying hole 91 in the tank 3 in this way, the nozzle 7 housed in the nozzle housing part 41 can be dried. In addition, the drying hole 91 is arranged to face the bottom wall side of the nozzle housing part 41 of the device body 5 in a state where the device body 5 is pulled out from the tank 3. By arranging the drying hole 91 in this way, water accumulated in the nozzle housing part 41 can be discharged from the drying hole 91.

[0060] In the tank-extending oral cleansing device 1, the tank 3 is composed of a cylindrical body 57 and a removable bottom wall 59, so it is possible to remove the bottom wall 59 and supply water to the storage section 9 in the tank 3. However, for example, when filling a washbasin with water, there is no problem if the water supply port is an extendable type such as a shower type, but if the water supply port is not extendable, it may be difficult to supply water by holding the tank 3 upright with the bottom wall 59 removed. For this reason, it is preferable to be able to supply water to the storage section 9 in the tank 3 even when the tank 3 is in a horizontal position.

[0061] Therefore, as shown in Figs. 8, 16 to 18, 22 and 23, a liquid supply hole 93 for injecting water into the storage section 9 is formed on the side of the tank 3. The liquid supply hole 93 is formed in a cylindrical shape protruding from the side of the tank 3. The liquid supply hole 93 is arranged so as to be located below the packing 55 when the device body 5 is pulled out of the tank 3. The liquid supply hole 93 is also arranged so as to be located above the packing 55 when the device body 5 is housed in the tank 3. By arranging the liquid supply hole 93 in this manner, the liquid supply hole 93 does not interfere with the packing 55, and the sealing property of the packing 55 can be maintained. The liquid supply hole 93 is closed by a liquid supply lid 95.

[0062] The liquid supply lid 95 is provided with a blocking portion 97 having an outer diameter larger than the outer diameter of the liquid supply hole 93. The contour of the blocking portion 97 is formed so as to be a track ellipse in which both sides in the vertical direction are formed with curved surfaces and both sides in the horizontal direction are formed with straight surfaces. The outer surface of the blocking portion 97 is curved so as to follow the side shape of the tank 3. By forming the blocking portion 97 in this manner, the design can be improved. On the inner surface of the blocking portion 97, a peripheral wall 99 that protrudes toward the liquid supply hole 93 and can be inserted into the inner circumference of the liquid supply hole 93 is formed continuously in the circumferential direction. The liquid supply lid 95 is attached to the tank 3 via a hinge 101 so as to be openable and closable in the vertical direction. Note that the liquid supply lid 95 may be provided so as to be openable and closable in the horizontal direction with respect to the tank 3 via the hinge 101, for example, and the opening and closing direction of the liquid supply lid 95 may be any direction.

[0063] Hinge 101 is composed of shaft 103 provided on tank 3 and hook 105 provided on liquid supply lid 95 which is rotatably engaged with shaft 103. By configuring hinge 101 with shaft 103 and hook 105, liquid supply lid 95 can be attached and detached to tank 3. This makes it possible to clean only liquid supply lid 95. Note that hook 105 may be provided on tank 3 and shaft 103 may be provided on liquid supply lid 95 to form hinge 101. Furthermore, the hinge may be configured to be formed continuously between tank 3 and liquid supply lid 95.

[0064] The hinge 101 is provided at a position where the entirety is hidden by the closing portion 97 of the liquid supply lid 95 in a front view. By hiding the hinge 101 with the liquid supply lid 95, the hinge 101 can be protected and damage to the hinge 101 can be suppressed. In addition, the strength of the hook 105 can be increased and the strength of the hinge 101 can be improved without providing the hook 105 at the end of the liquid supply lid 95. Note that at least a part of the hinge 101 may be hidden by the liquid supply lid 95 in a front view. Also, if the hinge 101 has high strength, the hinge 101 does not need to be hidden by the liquid supply lid 95. The hinge 101 is provided at a position where the user's fingers do not touch it when the user grips the bottom wall 59 to attach or detach the bottom wall 59 to or from the cylindrical body 57. By arranging the hinge 101 in this manner, the bottom wall 59 can be easily attached to and detached from the cylindrical body 57 without interference with the hinge 101 .

[0065] A packing 107 serving as a seal member is disposed between the liquid supply hole 93 and the liquid supply lid 95. The packing 107 is attached in close contact with a groove 109 formed continuously in the circumferential direction on the outer peripheral surface of the peripheral wall 99 of the liquid supply lid 95. The packing 107 is detachable from the groove 109. The outer peripheral surface of the packing 107 is in close contact with the inner peripheral surface of the liquid supply hole 93 when the liquid supply hole 93 is closed by the liquid supply lid 95. The packing 107 seals the gap between the liquid supply hole 93 and the liquid supply lid 95 by being in close contact with the liquid supply hole 93 and the liquid supply lid 95. The groove 109 may be provided on the inner peripheral surface of the liquid supply hole 93.

[0066] An upper wall portion constituting groove 109 in which packing 107 is attached is provided with notches 111 formed by cutting away from the outer circumferential surface of packing 107. A plurality of notches 111 (two in this example) are provided in the circumferential direction of groove 109. It is to be noted that notch 111 may be provided at one location in the circumferential direction of groove 109. Notches 111 allow a user to insert his or her finger into them to come into contact with the outer circumferential surface of packing 107. For this reason, packing 107 attached to groove 109 can be easily removed from groove 109.

[0067] Here, conventionally, when liquid supply lid 95 is opened relative to liquid supply hole 93, an end of liquid supply lid 95 protrudes from the side surface of tank 3 in a front view. For this reason, if tank 3 is dropped while liquid supply lid 95 is open, the protruding end of liquid supply lid 95 may collide with surrounding components, causing damage to hinge 101 that holds liquid supply lid 95.

[0068] 17 and 18, the end of liquid supply lid 95 is disposed within the range of the side surface of tank 3 when viewed from the front with liquid supply lid 95 open. In particular, the end of liquid supply lid 95 opposite hinge 101 is disposed in a position that does not protrude from the lower end of the side surface of tank 3 when viewed from the front with liquid supply lid 95 open. Therefore, when liquid supply lid 95 is open, it is possible to prevent the end of liquid supply lid 95 from interfering with surrounding components, and to suppress the effect on hinge 101.

[0069] In such an extendable-tank oral cleaning device 1, a locking portion 49 that holds the device body 5 to the tank 3 in a housed state is formed between the device body 5 and the tank 3. The locking portion 49 releases the holding of the device body 5 to the tank 3 by rotating the device body 5 relative to the tank 3. Therefore, by rotating the device body 5 relative to the tank 3, the device body 5 can be pulled out of the tank 3 in a state in which the holding of the device body 5 to the tank 3 by the locking portion 49 is released.

[0070] Therefore, in such an extendable tank type oral cleaning device 1, the device body 5 can be easily pulled out from the tank 3.

[0071] Furthermore, the device body 5 is rotated relative to the tank 3, and moves in a direction to be pulled out from the tank 3 when the holding of the device body 5 to the tank 3 by the locking portion 49 is released. This allows the device body 5 to be more easily pulled out from the tank 3 while achieving a more compact size when stored in the tank 3. In addition, when the holding of the tank 3 by the locking portion 49 is released, the amount by which the device body 5 protrudes from the tank 3 increases, making the device body 5 easier to grasp and allowing the device body 5 to be more easily pulled out from the tank 3.

[0072] Furthermore, in the pulled-out state, the locking portion 49 overlaps with the tank 3 in a front view. Therefore, when the device main body 5 is pulled out from the tank 3, the locking portion 49 is not exposed, and the design can be improved.

[0073] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims or their equivalents.
