According to such a beauty tool, the skin electrode 24 can be protected by the protective cap 51 when not in use. It is not necessary to remove the cap 11 from the skin electrode 24 and store it separately from the main body A when not in use, so that the cap 11 can be prevented from being mixed in or lost. In addition, when not in use, the cap 11 can be attached to the familiar skin electrode 24 for storage, so that the user convenience can be improved.

  According to the front protective part 52 covering the front surface of the skin electrode 24 and the protective cap 51 including the clip body B, the protective cap 51 can be easily attached to the main body part A simply by engaging the clip body B with the mounting part 22. Can be installed. Further, when the protective cap 51 is attached to the main body A, the front cover wall 54 and the skin electrode 24 of the front protection portion 52 face each other with a gap therebetween, so that the front cover wall 54 and the skin electrode 24 rub against each other. It is possible to reliably prevent the skin electrode 24 from being damaged.

  In the protective cap 51 including the front protective part 52 and the rear protective part 53, the front and rear protective parts 52, 53 are connected via a pair of elastically deformable strip-shaped horizontal bridge walls 60, and The clip body B was provided on the inner surface. According to such a protective cap 51, when the clip body B is engaged with the mounting portion 22 while being elastically deformed, the transverse bridge wall 60 is simultaneously elastically deformed to prevent the engagement load from being concentrated on the clip body B. Thus, it is possible to eliminate early fatigue failure.

  In the case where the horizontal bridge tie wall 60 is configured by the valley portion 62 that is recessed toward the inner surface side of the protective cap 51 and the peak portion 63 that protrudes toward the outer surface side, the horizontal bridge tie wall 60 is locked by a flat belt-like wall. In comparison, the length of the wall portion that is elastically deformed can be increased, and the lateral bridge wall 60 can be configured to be easily elastically deformed.

  According to the protective cap 51 in which the finger-hanging piece 66 projects from the outer surface of the horizontal bridge wall 60, the protection cap 51 is attached to and detached from the mounting portion 22 with the thumb and index finger applied to the left and right finger-hanging pieces 66. The cap 51 can be easily and properly attached and detached. Further, since the protective cap 51 can be properly attached to and detached from the mounting portion 22, it is possible to prevent the front cover wall 54 and the skin electrode 24 from rubbing with each other at the time of attachment and detachment, thereby preventing the skin electrode 24 from being damaged.

  When the finger-hanging piece 66 protrudes from the valley portion 62 of the side bridge enveloping wall 60, the structure of the valley portion 62 is reinforced by the finger-hanging piece 66, and the valley portion is elastically deformed when the side bridge enveloping wall 60 is elastically deformed in the expanding direction. It can control that 62 changes too much. Further, since the finger hanging piece 66 is provided in the vicinity of the clip body B, the pushing force and the extracting force applied to the finger hanging piece 66 can be effectively transmitted to the clip body B.

  When the front protection part 52 and the rear protection part 53 are connected by the upper bridge wall 61 and the stopper part 65 is formed on the inner surface thereof, the front protection part 52 and the rear protection part 53 are mounted in the state where the protective cap 51 is attached to the main body part A. Can be positioned by the stopper portion 65. Moreover, since the rear protection part 53 is supported by the three members of the left and right horizontal bridge walls 60 and the upper bridge wall 61, the structural strength of the rear protection part 53 can be enhanced.

  When the ventilation window 67 is opened between the upper bridge wall 61 and the left and right horizontal bridge walls 60, the surface of the main body A facing the ventilation window 67 in the state where the protective cap 51 is mounted on the main body A is outside space. Since it can face, drying of the cosmetic liquid etc. which adhered to the surface of the main body case 1 can be accelerated | stimulated.

As shown in FIG. 7, the cap 11 can be stored in a state of being attached to the cap attachment portion 23.

  In FIG. 4, the power supply unit 15 includes a battery case 26 fixed to the main body case 1 and a battery unit (battery) 27 loaded in the battery case 26. The skin electrode 24, the grip electrode 14, the heater 17, the Peltier Electric power is supplied to the element 18 and the indicator lamps 9 and 10, and electric power is supplied to a control circuit that drives these electrical components. Inside the battery case 26, a battery accommodating portion 28 for accommodating the battery unit 27 is provided. As shown in FIGS. 1 and 4, the battery case 26 has a rectangular case shape with a pair of left and right holding walls 29 </ b> L and 29 </ b> R and a pair of holding end walls 30 continuous with upper and lower ends (longitudinal ends) of the holding walls 29 </ b> L and 29 </ b> R. The loading port 31 is opened on the rear surface. In addition, a through hole serving as a relief portion 32 is formed in the inner back portion of the battery case 26, that is, between the left and right holding walls 29L and 29R. Holding claws 33 and 34 are provided on the upper and lower sides of the left and right opposing sides of the loading port 31 to restrict the battery unit 27 from coming out of the battery housing portion 28. As described above, when the holding claws 33 and 34 are provided on the opposite sides of the loading port 31, the peripheral surface of the battery unit 27 exposed to the outside of the loading port 31 is pressed and held by the holding claws 33 and 34. Can be reliably controlled from being removed from the battery case 26. In FIG. 4, since the battery case 26 and the front case 1a are viewed from the back side, the left-right relationship is reversed.

  As shown in FIG. 1, the holding claw 33 provided on the holding wall 29L having a partially arc-shaped cross section is formed as a partially arc-shaped protrusion continuous with the holding wall 29L. The provided holding claw 34 is formed as a protrusion refracted in an L shape. Further, the protruding length H1 of the latter holding claw 34 from the loading port 31 is set to be larger than the protruding length H2 of the former holding claw 33 from the loading port 31. An elastic piece 35 that presses the battery unit 27 loaded in the battery housing portion 28 toward the lower holding end wall 30 is provided on the inner surface of the upper holding end wall 30. A lead notch 36 for leading out the output lead 45 of the battery unit 27 is formed in the lower corner. Further, fastening seats 37 are formed overhanging on both upper and lower ends of the outer surfaces of the left and right holding walls 29L and 29R, and these fastening seats 37 are screwed (fastened bodies) to screw bosses 38 provided on the inner surface of the front case 1a. By fastening at 39, the battery case 26 is integrated with the front case 1a. On the wall surfaces corresponding to the holding claws 33 and 34 of the left and right holding walls 29L and 29R, a heat radiating window 40 is opened.

  As shown in FIG. 6, the battery unit 27 is configured by covering a battery main body 42 made of a round cylindrical secondary battery and a protective circuit board 43 disposed in close contact with the peripheral surface of the battery main body 42 with a shrink film 44. The output lead 45 is led out from the protection circuit board 43. When overcharge, overvoltage, or overdischarge occurs, the protection circuit board 43 activates switch means composed of IC and FET mounted on the board to shut off the power supply line. The battery unit 27 is preloaded in the battery housing portion 28 and integrated with the front case 1a in the manner described above. By fastening the rear case 1b to the front case 1a in this state, the battery unit 27 is fixed. Is enclosed in the main body case 1.

  The peripheral surface of the battery unit 27 loaded in the battery housing portion 28 is received by a pair of left and right holding walls 29L and 29R, and the peripheral surface of the battery unit 27 exposed outside the loading port 31 is held by the holding claws 33 and The battery unit 27 is prevented from coming out of the battery housing portion 28 by being held by the claw 34. At the same time, the battery unit 27 is pressed toward the lower holding end wall 30 by the elastic piece 35 that is elastically deformed, thereby restricting the battery unit 27 from moving in the longitudinal direction. In addition, a rubber elastic body 46 that is in close contact with the peripheral surface of the battery unit 27 is provided on the inner surface of the rear case 1b that faces the loading port 31, and the rear case 1b is fastened and fixed to the front case 1a. The battery unit 27 is pressed against the battery case 26 by the elastic body 46. As shown in FIG. 5, the elastic body 46 is made of a long rubber strip. As described above, when the elastic body 46 is provided on the inner surface of the rear case 1b, the battery 27 can be pressed against the battery case 26 by the elastic body 46 that is elastically deformed, and the movement of the battery 27 can be restricted. Further, even when there is a slight gap between the battery 27 and the holding claws 33 and 34, it is possible to prevent the generation of noise by restricting the rattling of the battery 27 with the elastic body 46.

  As described above, the protruding length H1 of the holding claw 34 from the loading port 31 is set to be longer than the protruding length H2 of the holding claw 33 from the loading port 31. This is to facilitate loading into the accommodating portion 28. Specifically, when the battery unit 27 is loaded, the battery unit 27 is placed between the holding claw 34 and the holding wall 29R with the protective circuit board 43 side as the loading start end as shown by an imaginary line in FIG. Is temporarily assembled. In this state, the arc peripheral surface of the battery unit 27 is pressed against the holding claw 33, and the holding claws 33 and 34 are loaded into the battery housing portion 28 while being elastically deformed, and the battery unit 27 is loaded into the battery housing portion 28. In other words, the battery unit 27 is temporarily assembled by attaching the battery unit 27 to the side of the holding claw 34 having the large protrusion length H1, and the pushing operation is performed by attaching the peripheral surface of the battery unit 27 to the holding claw 33 having the small protrusion length H2. Thus, the battery unit 27 can be snapped into the battery case 26. Note that the protruding end of the holding claw 34 and the protruding end of the holding claw 33 are located at a position lower than the top of the battery unit 27 loaded in the battery case 25 (the position where it hits the elastic body 46). This is because if the protruding end of the holding claw 34 and the protruding end of the holding claw 33 are at a position higher than the top of the battery unit 27, the height space occupied by the battery case 25 and the battery unit 27 increases, and the size cannot be reduced.

  As described above, in a state where the battery unit 27 is loaded in the battery housing portion 28, a part of the peripheral surface of the battery unit 27 enters the escape space S of the escape portion 32 from the inner surfaces of the holding walls 29L and 29R. . As shown in FIG. 6, the amount T2 of the battery unit 27 entering the escape space S is preferably half or more of the thickness T1 of the escape space S. Incidentally, if the amount T2 of the battery unit 27 entering is less than half the thickness T1 of the escape space S, the effect of reducing the space occupied by the battery 27 and the battery case 26 in the main body case 1 cannot be sufficiently exhibited. More preferably, as shown in FIG. 6, the amount T2 of the battery 27 may be the same as the thickness T1 of the escape space S. In this case, the lower part of the arc peripheral surface of the battery unit 27 is below the escape portion 32. It becomes flush with the opening surface.

  When the escape portion 32 is formed at the inner back (front back) of the battery case 26, a part of the peripheral surface of the battery unit 27 is in the escape space S of the escape portion 32 in a state where the battery unit 27 is loaded in the battery housing portion 28. Therefore, the space occupied by the battery 27 and the battery case 26 in the main body case 1 can be reduced, and the main body case 1 can be made compact accordingly. Further, in a state where the battery unit 27 is loaded in the battery housing portion 28, since the two places on the peripheral surface of the battery unit 27 are received by the left and right peripheral walls of the escape space S, the battery unit 27 is held in a stable state. it can.

  If the escape portion 32 is formed as a through hole at the inner back (front back) of the rectangular case-shaped battery case 26, the structural strength of the battery case 26 is likely to be lowered and fragile. However, when the fastening seats 37 are extended to both ends of the outer surfaces of the holding walls 29L and 29R of the battery case 26 and these fastening seats 37 are fixed to the main body case 1 with screws 39, the holding walls 29L and 29R that have received an external force bend. It is possible to reliably prevent deformation. Therefore, the structural strength of the battery case 26 can be increased to improve the durability, and the case strength of the main body case 1 can be reinforced by the battery case 26 to increase the rigidity.

  In order to protect the heating head 3 and the cooling head 4 of the beauty tool when not in use, a protective cap 51 that covers the entire skin treatment head 2 is provided. As shown in FIGS. 7 and 8, the protective cap 51 is provided on the front protective portion 52 that covers the front surface and the upper surface of the thermal head 3 and the skin electrode 24, the upper portion of the main body case 1, and the upper rear surface of the case 1. It consists of a helmet-like plastic molded product provided with a rear protection portion 53 that covers the cooling head 4. The front protection part 52 includes a circular front cover wall 54 that covers the front surface of the thermal head 3 and the skin electrode 24, and a front concavity taper-shaped front support wall 55 that covers the upper half peripheral surface of the skin electrode 24 and the cap mounting part 23. I have. Further, the rear protection part 53 includes a rear support wall 57 that covers the upper peripheral surface of the main body case 1 and a circular rear cover wall 58 that covers the rear surface of the cooling head 4.

  The front protection part 52 and the rear protection part 53 are integrated via a pair of left and right elastically deformable belt-like horizontal bridge enveloping walls 60 and a belt-like upper bridge encircling wall 61 that connects the upper portions of the two protection parts 52 and 53. It is. Each of the bridge walls 60 and 61 is configured in an m shape with a valley portion 62 that is recessed toward the inner surface side of the protective cap 51 and a mountain portion 63 that is continuous with the valley portion 62 and protrudes toward the outer surface side. A clip piece 64 is provided on the inner surface of the valley portion 62 of the bridge wall 60, and a stopper portion 65 is provided on the inner surface of the valley portion 62 of the upper bridge wall 61. In addition, a triangular finger-hanging piece 66 for attaching and detaching the protective cap 51 protrudes from the lower outer surface of the valley portion 62 of the pair of horizontal bridge enveloping walls 60. A front support wall 55 and a rear support wall 57 between the horizontal bridge wall 60 and the upper bridge wall 61 are cut out as ventilation windows 67. As described above, when the ventilation window 67 is opened between the upper bridge wall 61 and the left and right horizontal bridge walls 60, the skin treatment head facing the ventilation window 67 in a state where the protective cap 51 is mounted on the upper part of the main body A. 2 and the surface of the main body A can be exposed to the external space, so that drying of the cosmetic liquid or the like attached to the surface of the skin treatment head 2 or the main body case 1 can be promoted.

  As described above, when the side bridge 62 and the peak 63 constitute the side bridge 60, the wall portion that is elastically deformed is compared to the case where the side bridge 60 is locked by a flat belt-like wall. The length can be increased so that the side bridge 60 can be easily elastically deformed. In addition, since the finger hanging pieces 66 project from the outer surface of the horizontal bridge wall 60, the protective cap 51 can be easily attached to and detached from the neck portion 22 with the thumb and index finger applied to the left and right finger hanging pieces 66. Moreover, it can be attached and detached accurately. In addition, since the protective cap 51 can be accurately attached to and detached from the neck portion 22, it is possible to prevent the front cover wall 54 and the skin electrode 24 from rubbing each other during attachment and detachment. In particular, when the finger-hanging piece 66 protrudes from the valley portion 62, the structure of the valley portion 62 is reinforced by the finger-hanging piece 66, and the valley portion 62 is elastically deformed in the lateral bridge enveloping wall 60 in the expanding direction. Can be prevented from excessively deforming. Further, since the finger hanging piece 66 is located in the vicinity of the clip body B, the pushing force and the extracting force applied to the finger hanging piece 66 are effectively transmitted to the clip body B, and the protective cap 51 is skin treated with an appropriate click feeling. It can be attached to and detached from the head 2.

  As shown in FIG. 10, the clip body B includes a clip piece 64 and a partially arcuate clip claw 70 that can be elastically deformed in the left-right direction at the inner lower portion of the clip piece 64. By press-fitting and attaching the clip claw 70 to the neck portion 22 of the head case 13, the protective cap 51 attached to the main body portion A can be held unremovably. The clip claw 70 in this state is in close contact with the lower half circumferential surface of the neck 22 having a circular cross section, and draws the protective cap 51 downward by its own elastic deformation force. Thereby, the protective cap 51 is self-held with respect to the main body part A by its own elastic deformation force. When the protective cap 51 is attached to the main body A, even if the cap 11 for holding the cotton sheet M is still attached to the cap attaching portion 23, it can be attached without any problem. As shown in FIGS. 7 and 9, the inner surface of the front support wall 55 and the skin electrode 24 and the head case 13 face each other with a sufficient gap. This is because the protective cap 51 does not buffer the cap 11. Therefore, it is not necessary to remove the cap 11 from the skin electrode 24 and store and store it separately from the main body A when not in use, and the cap 11 can be reliably prevented from being mixed in or lost. The protective cap 51 not only protects the skin electrode 24 (thermal head 3) and the cooling head 4, but also the upper half peripheral surface of the cap 11 that is stored and stored around the skin electrode 24 in a state of being engaged with the cap mounting portion 23. The cap 11 is protected from impact or the like. Since the gap between the front cover wall 54 and the skin electrode 24 is smaller than the front and rear thicknesses of the cap 11 (see FIG. 7), even if the cap 11 may fall off the cap mounting portion 23, the protective cap 51 Never fall outside. That is, when the protective cap 51 is attached to the main body A, the cap 11 cannot be removed or attached due to the presence of the protective cap 51. Further, even if the protective cap 51 is removed from the main body A, the cap 11 remains alone on the skin electrode 24, and at the same time, it is possible to prevent the protective cap 51 and the cap 11 from being mixed into a bag or the like as much as possible. In some cases, the protective cap 51 is attached to the main body A while the sheet-like liquid absorption M such as a cotton sheet is fixed to the skin electrode 24 by the cap 11, and the sheet-like liquid absorbent M, the cap 11 and the The three skin electrodes 24 can be protected from external force. In this case, the user can make the cosmetic liquid soak into the sheet-like liquid absorption M immediately after removing the protective cap 51, and can reduce labor for skin care.

  The stopper portion 65 includes a base wall 71 projecting from the inner surface of the valley portion 62 of the upper bridge wall 61 and four regulating ribs 72 projecting from the front surface of the base wall 71. As shown in FIGS. 7 and 10, in a state where the protective cap 51 is mounted on the main body portion A, the base wall 71 and the regulating rib 72 are in contact with the upper peripheral surface of the neck portion 22 and the downward movement is restricted.
