Inside the battery case 26, a battery housing portion 28 that houses the battery unit 27 is provided. As shown in FIG. 1 and FIG. 4, the battery case 26 has a rectangular case shape with a pair of left and right holding walls 29L and 29R and a pair of holding end walls 30 continuous to the upper and lower ends (both ends in the longitudinal direction) of the holding walls 29L and 29R. The loading port 31 is opened on the rear surface. Further, a through hole serving as an escape 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 for restricting the battery unit 27 from coming out of the battery accommodating portion 28 are provided above and below the left and right opposite sides of the loading port 31, respectively. 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 held and held by the holding claws 33 and 34, and the battery unit 27 is held. Can be reliably regulated from being removed from the battery case 26. Since the battery case 26 and the front case 1a are viewed from the back side in FIG. 4, the left-right relationship is reversed.

  As shown in FIG. 1, the holding claw 33 provided on the holding wall 29L having a partial arcuate cross section is formed as a partial arcuate projection continuous to the holding wall 29L, but is formed on the holding wall 29R whose cross section is bent. The holding claw 34 provided is formed as a protrusion that is bent into an L shape. Further, the projection length H1 of the latter holding claw 34 from the loading port 31 is set to be larger than the projection 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 at the 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 to a screw boss 38 provided on the inner surface of the front case 1a. By fastening with 39, the battery case 26 is integrated with the front case 1a. A heat radiating window 40 is opened on the wall surface of the left and right holding walls 29L and 29R corresponding to the holding claws 33 and 34, respectively.

  As shown in FIG. 6, the battery unit 27 is configured by covering a battery main body 42, which is a round tubular secondary battery, and a protective circuit board 43 closely arranged on the peripheral surface of the battery main body 42 with a shrink film 44. Yes, the output lead 45 is led out from the protection circuit board 43. When the overcharge, overvoltage, and overdischarge occur, the protection circuit board 43 operates the switch means composed of the IC and the FET mounted on the board to shut off the power supply line. The battery unit 27 is preliminarily loaded in the battery accommodating portion 28 and is integrated with the front case 1a in the manner described above. By fastening and fixing the rear case 1b to the front case 1a in this state, the battery unit 27 is Is enclosed in the body case 1.

  The peripheral surface of the battery unit 27 loaded in the battery housing portion 28 is received by the pair of left and right holding walls 29L and 29R, and the peripheral surface of the battery unit 27 exposed to the outside of the loading port 31 is held by the holding claw 33 and the holding claw 33. The claw 34 holds and holds the battery unit 27 to prevent the battery unit 27 from coming out of the battery housing portion 28. At the same time, the elastically deformed elastic piece 35 presses the battery unit 27 toward the lower holding end wall 30 to prevent the battery unit 27 from moving in the longitudinal direction. Furthermore, an elastic body 46 made of rubber 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 elastic deformation occurs when 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 rubber strip that is long in the vertical direction. As described above, when the elastic body 46 is provided on the inner surface of the rear case 1b, the elastically deformed elastic body 46 presses the battery 27 against the battery case 26, and the movement of the battery 27 can be restricted. Further, even if there is a slight gap between the battery 27 and the holding claws 33 and 34, it is possible to prevent the rattling of the battery 27 by the elastic body 46 and prevent the generation of abnormal noise.

  As described above, the projecting length H1 of the holding claw 34 from the loading port 31 is set to be larger than the projecting length H2 of the holding claw 33 from the loading port 31. This is for facilitating the loading into the accommodation portion 28. Specifically, when loading the battery unit 27, the protection circuit board 43 side is set as the loading start end as shown by the phantom line in FIG. 6, and the battery unit 27 is applied between the holding claw 34 and the holding wall 29R. Temporary assembly. In this state, the circular arc peripheral surface of the battery unit 27 is pressed against the holding claws 33, and the holding claws 33 and 34 are elastically deformed and loaded into the battery housing portion 28, and the battery unit 27 is loaded into the battery housing portion 28. In other words, the battery unit 27 is temporarily assembled by applying the battery unit 27 to the holding claw 34 side having a large protrusion length H1, and the peripheral surface of the battery unit 27 is pressed to the holding claw 33 on the side having a small protrusion length H2 to perform an operation. Then, the battery unit 27 can be snapped into the battery case 26. The tip of the holding claw 34 and the tip 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 is in contact with the elastic body 46). This is because if the projecting end of the holding claw 34 and the projecting end of the holding claw 33 are located 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 it cannot be made compact.

  As described above, in the 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 entry amount T2 of the battery unit 27 in the escape space S is preferably half or more of the thickness T1 of the escape space S. Incidentally, if the entering amount T2 of the battery unit 27 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 inside the main body case 1 cannot be sufficiently exerted. More preferably, as shown in FIG. 6, the entering amount T2 of the battery 27 is preferably the same as the thickness T1 of the escape space S, and in that case, the lower portion of the circular arc peripheral surface of the battery unit 27 is below the escape portion 32. It is flush with the opening surface.

  When the escape portion 32 is formed on the inner side (front side) of the battery case 26, a part of the peripheral surface of the battery unit 27 is inside the escape space S of the escape portion 32 when the battery unit 27 is loaded in the battery housing portion 28. Since the space is occupied by the battery 27 and the battery case 26 inside the body case 1, the body case 1 can be made compact by that much. Further, when the battery unit 27 is loaded in the battery accommodating portion 28, the two peripheral portions of the battery unit 27 are received by the left and right peripheral walls of the escape space S, so that the battery unit 27 is held in a stable state. it can.

  If the escape portion 32 is formed as a through hole in the inner side (front side) of the rectangular case-shaped battery case 26, the structural strength of the battery case 26 is apt to decrease and become 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 the fastening seats 37 are fixed to the main body case 1 with the screws 39, the holding walls 29L and 29R subjected to the external force are bent. It can be surely prevented from being deformed. Therefore, the structural strength of the battery case 26 can be increased to improve the durability, and the battery case 26 can reinforce the case strength of the main body case 1 to increase the rigidity.

  In order to protect the hot head 3 and the cold head 4 of the beauty tool in the unused state, 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 and upper surfaces 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 same case 1. It is made of a helmet-shaped plastic molded product having a rear protective portion 53 that covers the cold head 4. The front protection portion 52 includes a circular front cover wall 54 that covers the front surfaces of the thermal head 3 and the skin electrode 24, and a front recessed tapered front support wall 55 that covers the skin electrode 24 and the upper half peripheral surface of the cap mounting portion 23. I have it. Further, the rear protection part 53 includes a rear support wall 57 that covers the upper end 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 through a pair of left and right elastically deformable strip-shaped horizontal bridging walls 60 and a strip-shaped upper bridging wall 61 that connects the upper parts of both the protection parts 52 and 53. There is. Each bridging wall 60/61 is formed in an m-shape by 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 projects toward the outer surface side. The clip piece 64 is provided on the inner surface of the valley portion 62 of the bridge wall 60, and the stopper portion 65 is provided on the inner surface of the valley portion 62 of the upper bridge wall 61. Further, a triangular finger-hanging piece 66 for attaching and detaching the protective cap 51 is projectingly provided on the lower outer surface of the valley portion 62 of the pair of lateral bridge walls 60. The front support wall 55 and the rear support wall 57 between the horizontal bridge wall 60 and the upper bridge wall 61 are hollowed out as a ventilation window 67. Thus, when the ventilation window 67 is opened between the upper bridge wall 61 and the left and right lateral bridge walls 60, the skin treatment head facing the ventilation window 67 in the state where the protective cap 51 is mounted on the upper portion of the main body portion A. Since the surface of 2 and the main body portion A can be exposed to the external space, it is possible to promote the drying of the cosmetic liquid adhered to the surfaces of the skin treatment head 2 and the main body case 1.

  As described above, when the horizontal bridging wall 60 is configured by the valley portion 62 and the mountain portion 63, compared with the case where the horizontal bridging wall 60 is locked by a flat strip-shaped wall, The length can be increased so that the lateral bridge wall 60 can be easily elastically deformed. Moreover, since the finger hooks 66 are provided on the outer surface of the lateral bridge wall 60, the protection cap 51 can be easily attached to and detached from the neck portion 22 with the thumb and forefinger applied to the left and right finger hooks 66. Moreover, it can be attached and removed accurately. Further, since the protective cap 51 can be properly 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 against each other when attaching and detaching. Particularly, when the finger hooking piece 66 is provided so as to project from the valley portion 62, the structure of the valley portion 62 is reinforced by the finger hooking piece 66, and the valley portion 62 is elastically deformed when the lateral bridge wall 60 is elastically deformed in the expanding and unfolding direction. Can be prevented from excessive deformation. Further, since the finger-hooking piece 66 is located near the clip body B, the pushing force and the withdrawing force applied to the finger-hooking piece 66 are effectively transmitted to the clip body B, and the protective cap 51 is skin-treated with a proper click feeling. Can be attached to and detached from the head 2.

  As shown in FIG. 10, the clip body B is configured to include a clip piece 64 and a partial arcuate clip claw 70 that is elastically deformable in the left-right direction at an inner lower portion of the clip piece 64, By fitting the clip claw 70 onto the neck portion 22 of the head case 13 by pressure fitting, the protective cap 51 attached to the main body portion A can be held so as not to be removed. The clip claw 70 in this state is in close contact with the lower half peripheral surface of the neck 22 having a circular cross section, and pulls the protective cap 51 downward by its own elastic deformation force. As a result, the protective cap 51 is self-held with respect to the main body portion A by its own elastic deformation force. When the protective cap 51 is attached to the main body portion 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 are opposed to each other with a sufficient gap, so that the protection cap 51 is not only attached but also after the attachment. Also in the above, 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 the cap 11 separately from the main body portion A when not in use, and it is possible to reliably prevent the cap 11 from slipping into somewhere or being lost. The protective cap 51 not only protects the skin electrode 24 (the heating head 3) and the cooling head 4, but also the upper half peripheral surface of the cap 11 which is stored and stored around the skin electrode 24 while being engaged with the cap mounting portion 23. To protect the cap 11 from shocks and the like. Since the gap between the front cover wall 54 and the skin electrode 24 is smaller than the front-rear thickness of the cap 11 (see FIG. 7), even if the cap 11 may fall off the cap mounting portion 23, the protective cap 51 may be removed. Will not fall out of the room. That is, when the protective cap 51 is attached to the main body portion 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 portion 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 slipping 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-shaped liquid absorbent M such as a cotton sheet is fixed to the skin electrode 24 by the cap 11, and the protective cap 51 allows the sheet-shaped liquid absorbent M, the cap 11 and The skin electrodes 24 can be protected from external forces. In this case, the user can allow the cosmetic liquid to soak into the sheet-shaped liquid absorbent M immediately after removing the protective cap 51, and can reduce the labor for skin care.

  The stopper portion 65 includes a base wall 71 protruding from the inner surface of the valley portion 62 of the upper bridge wall 61, and four restricting ribs 72 protruding from the front surface of the base wall 71. As shown in FIGS. 7 and 10, when the protective cap 51 is attached to the main body portion A, the base wall 71 and the regulation rib 72 contact the upper peripheral surface of the neck portion 22, and the downward movement is regulated. There is.
