DETAILED DESCRIPTION

[0042] Hereinafter, embodiments of the skin beautifying device of the present invention will be described with reference to the drawings. Each direction of the skin beautifying device in the illustrated embodiment, i.e., up and down, front and back, and left and right, is defined as described in the drawings.

[0043] like Figure 1 to Figure 5 As shown, the skin care device 10 of this embodiment is constructed as a handheld device having a shape and size that can be held in the palm of the hand, and has a shell 12 forming an outer shell, a rigid circuit board 14 housed in the shell 12, and a cover 13 that selectively closes the front end of the shell 12 that should form an irradiation end.

[0044] The housing 12 is formed into a substantially circular flat plate shape when viewed from above, and is a shape obtained by flattening a sphere. The housing 12 of this shape is easy to hold by hand, and the operability of the skin beautification device 10 is improved. The skin beautification device 10 has a smooth outer shape in the vertical direction, such as a sphere flattened, when the cover 13 is mounted on the front of the housing 12.

[0045] The rigid circuit board 14 is made of a hard material, such as Figure 3 and Figure 4 As shown in FIG. , it is a roughly circular flat plate when viewed from above. Figure 5 As shown, a front support body (first support body) 16 is fixed to the front end portion 14A (first end portion) of the rigid circuit board 14. More specifically, the front support body 16 is a resin molded product of a rigid structure that is long in the left-right direction and forms a front portion of a shape obtained by flattening a joint sphere. The front support body 16 integrally includes: upper and lower wall portions 16A formed by curved walls that form a part of a spherical shape (hereinafter referred to as a flat sphere) flattened in the upper and lower directions; left and right side wall portions 16B formed by flat vertical walls; and a front wall portion 16C formed by a flat vertical wall, and most of the resin molded product is housed in the housing 12 (front housing 24).

[0046] Each of the left and right side wall portions 16B of the front support body 16 has a slit 18 in which the middle portion in the vertical direction extends horizontally and opens toward the rear. The outer edge portions of the left and right corresponding sides of the front end portion 14A of the rigid circuit board 14 are fitted into each slit 18. The front support body 16 is fixed to the front end portion 14A of the rigid circuit board 14 at each side wall portion 16B by means of screws 19. That is, the front support body 16 and the front end portion 14A of the rigid circuit board 14 are connected to each other by screwing with the screws 19.

[0047] like Figure 5 As shown, a rear support body (second support body) 20 is fixed to a rear end portion 14B (second end portion) of the rigid circuit board 14 that is away from the front end portion 14A in the front-to-back direction. The rear support body 20 is a resin molded product of a rigid structure, which forms a rear portion of a shape obtained by flattening a joint sphere. The rear support body 20 is accommodated in the housing 12. The rear support body 20 has a smaller front-to-back length than the front support body 16. The rear support body 20 has a rear surface 20B that forms a part of a flat sphere and a front surface 20A that is substantially parallel to the rear surface 20B.

[0048] The rear support body 20 has a shelf portion 20C extending forward from the front surface 20A. The shelf portion 20C has a substantially flat upper surface. The rear support body 20 is fixed to the rear end portion 14B of the rigid circuit board 14 by two left and right screws 23 in a state where the lower surface of the rear end portion 14B of the rigid circuit board 14 is in contact with the upper surface of the shelf portion 20C in a planar manner.

[0049] In other words, the front support 16 and the rear support 20 are located at positions separated from each other in the front and rear directions, and are connected to each other through the rigid circuit board 14 extending horizontally in the front and rear directions between the two. Thus, the rigid circuit board 14, the front support 16, and the rear support 20, which are separate rigid components, are assembled to form an assembly of a rigid structure.

[0050] In this structure, the rigid circuit board 14 also serves as a connecting member that connects the front support body 16 and the rear support body 20. Since the front support body 16 and the rear support body 20 are separated from each other and the rigid circuit board 14 constitutes a connecting member between the front support body 16 and the rear support body 20, the front support body 16 and the rear support body 20 are each miniaturized compared to a case where the two are an integral member that is continuous front and back.

[0051] like Figure 3 to Figure 5 As shown, the housing 12 includes a dividing line (joining line) P (see Figure 1 and Figure 2 ) is divided into a front housing 24 and a rear housing 26. The housing 12 is formed into a hollow shape that covers the rigid circuit board 14, the front support body 16, and the rear support body 20 by combining the front housing 24 and the rear housing 26, and is a shape obtained by flattening the joint ball. By making the housing 12 consist of the combination of the front housing 24 and the rear housing 26, the moldability of the front housing 24 and the rear housing 26 is good, and the degree of freedom of their design is improved.

[0052] The housing 12 composed of the front housing 24 and the rear housing 26 has a substantially circular flat plate shape in a plan view, which is a shape obtained by flattening a sphere, and is therefore easy to hold by hand, thereby improving the operability of the skin beautifying device 10.

[0053] The dividing line P is a joining line where the front housing 24 and the rear housing 26 are joined to each other, and is located at the center Pc in the extending direction (radial direction) (see Figure 1 ) is a smooth curved shape bulging forward. The rear housing 26 includes a bulging portion 27 on the front side that bulges toward the front housing 24 in the center of the left-right direction in the curved shape of the dividing line P. As a result, the central portion of the housing 12 when viewed from above belongs to the rear housing 26.

[0054] The front case 24 has an outer contour that is smaller than the rear case 26 by an amount corresponding to the thickness of the cover 13. The cover 13 is fitted to the outside of the front case 24 and defines a smooth outer contour without steps in cooperation with the rear case 26.

[0055] Regarding the skin care device 10, even when the cover 13 is installed on the housing 12, the housing 12 has a smooth shape like a flattened sphere, so it is not bulky and easy to hold, and the ease of carrying such as putting it in a bag is improved.

[0056] The front housing 24 is formed into a hollow body having a shape roughly imitating the outer surface shape of the front support body 16 and opening toward the rear, and accommodates the front support body 16. The front housing 24 is fitted with the upper and lower surfaces of the front support body 16 and the arc-shaped left and right side edges 14C of the rigid circuit board 14, and is combined with the front support body 16 and the rigid circuit board 14.

[0057] The rear housing 26 has an upper wall portion 26A, which is located above the rigid circuit board 14 and is in a plane parallel to the rigid circuit board 14; a lower wall portion 26B, which is located below the rigid circuit board 14 and is parallel to the rigid circuit board 14; and a rear wall portion 26C, which connects the rear edges of the upper wall portion 26A and the lower wall portion 26B to each other, and the planar shape of the rear wall portion 26C is approximately semicircular and the cross-sectional shape is approximately semicircular, and the rear housing 26 forms a hollow body opened toward the front. The front ends of the upper wall portion 26A and the lower wall portion 26B of the rear housing 26 are fitted with the upper and lower surfaces of the front support body 16, and the rear wall portion 26C is fitted with the rear support body 20, and the rear housing 26 is combined with the front support body 16 and the rear support body 20.

[0058] The rear housing 26 further includes an engagement groove 30 extending in the front-rear direction along the inner surface of the left and right side wall portions 26D (see FIG. Figure 3 ). The arc-shaped side edges 14C on the left and right corresponding sides of the rigid circuit board 14 are inserted into the left and right engaging grooves 30 of the rear housing 26 from the front side. As a result, the engaging grooves 30 engage with the side edges 14C of the rigid circuit board 14, and the rear housing 26 is supported by the rigid circuit board 14. In other words, the rear housing 26 is combined with the rigid circuit board 14 in a disassembled manner by the engagement between the engaging grooves 30 and the side edges 14C of the rigid circuit board 14. In addition, as a result, the rear housing 26 and the rigid circuit board 14 can be assembled with each other simply and reliably.

[0059] The front case 24 accommodates the front support body 16 and the rigid circuit board 14 , and the rear case 26 accommodates the rear support body 20 . Thus, the storage is shared and space efficiency is good.

[0060] like Figure 3As shown, the front housing 24 and the rear housing 26 are fastened (combined) to each other by two screws 32 extending in the front-to-back direction to form a housing 12. The front housing 24 has a profile that is reduced or sunken compared to the rear housing 26, and the cover 13 is configured to cover the front housing 24 exclusively, and the cover 13 cooperates with the rear housing 26 to define a smooth outer contour as a whole.

[0061] Through the above structure, the rigid circuit board 14 supports the front end 14A and the rear end 14B on the front shell 24 and the rear shell 26 combined with the shell 12. The rigid circuit board 14 extends like a spine between the front shell 24 and the rear shell 26, defining a flat upper chamber 34 and a lower chamber 36 that divide the shell 12 into upper and lower parts.

[0062] The front support body 16 supports the irradiation device 40 and the movement amount sensor 50 at the front.

[0063] like Figure 5 As shown, the irradiation device 40 includes a concave reflector 42 that is long in the left-right direction and opens toward the front, and a xenon discharge tube 44 that is long in the left-right direction and is arranged at the focal position of the concave reflector 42. The front housing 24 has a flat front wall portion 24A located in front of the front support body 16. A rectangular irradiation window 46 that is long in the left-right direction and located in front of the opening of the concave reflector 42 is formed on the front wall portion 24A. A protective cover glass 48 made of transparent flat glass that matches the irradiation window 46 is installed on the front wall portion 24A. The xenon discharge tube 44 flashes intermittently by arc discharge. Thus, the irradiation device 40 uses the xenon discharge tube 44 as a light source and intermittently irradiates light from the irradiation window 46 toward the front.

[0064] The movement sensor 50 is an input device similar to an optical mouse with a microcomputer. It repeatedly takes pictures of the skin of a specified area at specified intervals through an opening 51 formed in the front shell 24, and detects the movement amount and direction of the shell 12 relative to the skin based on the image data of the skin at specified intervals.

[0065] Electrode plates 54 of the capacitive touch sensor 52 are mounted on both left and right sides of the front wall 16C of the front support body 16. Each electrode plate 54 is configured as an arc-shaped strip extending along the left and right arc-shaped edges of the front wall 16C of the front support body 16. The touch sensor 52 detects whether the skin is in contact with the front surface of the front wall 24A by bringing each electrode plate 54 close to the back surface (rear surface) of the front wall 24A of the front housing 24.

[0066] On one side (upper surface) of the rigid circuit board 14, electrical components such as a capacitor 56 and a transformer 58 constituting a DC-DC converter are mounted on the rigid circuit board 14 so as to be accommodated in the upper chamber 34. The electrical components such as the capacitor 56 and the transformer 58 constitute an irradiation drive circuit 60 that drives the irradiation device 40.

[0067] On the other surface (lower surface) of the rigid circuit board 14 , a battery pack 63 including a plurality of secondary batteries 62 that forms a power source for the entire skin care device 10 is arranged so as to be housed in the lower chamber 36 .

[0068] Thus, capacitor 56, transformer 58, and battery pack 63 are compactly arranged vertically with rigid circuit board 14 interposed therebetween. Thus, these electrical components can be electrically connected to rigid circuit board 14 without requiring long terminals or leads.

[0069] In the upper chamber 34, a flexible circuit board 64 is arranged so as to cover the capacitor 56 and the transformer 58 from the side opposite to the rigid circuit board 14. The flexible circuit board 64 is a flexible and bendable circuit board and is electrically connected to the rigid circuit board 14. Electronic components such as a CPU chip 66 and a memory chip 68 are mounted on the flexible circuit board 64. The electronic components such as the CPU chip 66 and the memory chip 68 constitute a control circuit 70 of the irradiation device 40.

[0070] like Figure 4 As shown, an operation switch 71 as well as a power switch 72 as a working switch, an increase side strength adjustment switch 74 and a decrease side strength adjustment switch 76 are mounted on the flexible circuit board 64 .

[0071] By forming a control circuit 70 on a bendable flexible circuit board 64 and installing a power switch 72, an increasing side strength adjustment switch 74 and a decreasing side strength adjustment switch 76, the skin beautification device can be miniaturized and the degree of freedom in shape design is improved.

[0072] The operation switch 71 is located at a position corresponding to the upper surface of the transformer 58 of the irradiation device 40, and is supported by the transformer 58. The rear housing 26 is provided with a flexible operation button 78 for pressing the operation switch 71 at a position corresponding to the operation switch 71. The operation switch 71 is turned on by pressing the operation button 78. The operation button 78 is coplanar with the upper surface of the upper wall portion 26A of the rear housing 26 in the non-operation state (non-pressed state). The operation button 78 is located at the bulging portion 27 of the rear housing 26. Thus, the operation button 78 is located approximately in the center of the circular upper surface of the housing 12, and the operability of the operation switch 71 performed in a state where the housing 12 is held with one hand is good.

[0073] The power switch 72, the increase side strength adjustment switch 74, and the decrease side strength adjustment switch 76 are located at a position corresponding to the rear surface 20B of the rear side support body 20 and are supported by the rear side support body 20. The rear side housing 26 is formed with an opening (not shown) 26E at a position corresponding to the power switch 72. An operation button 80 (see FIG. 26E ) for pressing the power switch 72 is fitted into the opening. Figure 3 and Figure 4 ). An opening 26F common to the two switches is formed in the rear housing 26. A seesaw-type operation button 82 for performing opposite operations on the increase-side intensity adjustment switch 74 and the decrease-side intensity adjustment switch 76 is embedded in the opening 26F. The operation buttons 80 and 82 are coplanar with the outer surface of the rear wall portion 26C of the rear housing 26 in the non-operating state.

[0074] A charging port 84 for a secondary battery is mounted on the rear support body 20. The charging port 84 is formed of, for example, a USB and is electrically connected to the flexible printed circuit 64. An access port 26G is opened at a position corresponding to the charging port 84 in the rear housing 26.

[0075] A light emitting element 86 forming an indicator light of a power source is mounted on the upper surface of the flexible printed circuit 64. A light guide member 88 optically connected to the light emitting element 86 is mounted near the dividing line P of the front support body 16. The light guide member 88 has an upper surface 88A coplanar with the upper surface of the upper wall portion 26A of the rear housing 26 and guides light from the light emitting element 86 to the upper surface 88A.

[0076] The skin beautifying device 10 of this embodiment has excellent miniaturization design by the arrangement of the above-mentioned components and the supporting structure of the components, etc. Therefore, even if the capacitor 56 and the transformer 58 required to obtain the required output are large, the skin beautifying device 10 is easy to carry.

[0077] In addition, the flexible circuit board 64 can be bent, and has a high degree of freedom in its configuration in the narrow space of the housing 12. As a result, the degree of freedom in the miniaturized design of the skin beautifying device 10 is improved, and the degree of freedom in the configuration position of the power switch 72 and the increase side strength adjustment switch 74 and the decrease side strength adjustment switch 76 on the flexible circuit board 64 can be improved without hindering the degree of freedom in the miniaturized design of the skin beautifying device 10. As a result, the power switch 72 and the increase side strength adjustment switch 74 and the decrease side strength adjustment switch 76 can be easily configured at positions that are easy to operate, respectively. Conversely, the power switch 72 and the increase side strength adjustment switch 74 and the decrease side strength adjustment switch 76 can also be configured at positions that are not easily misoperated in order to improve safety.

[0078] With the above-mentioned structure, the skin beautifying device 10 is small and easy to carry.

[0079] The control circuit 70 controls the flash of the xenon discharge tube 44 in such a manner that the irradiation device 40 performs intermittent irradiation when the operation button 78 is pressed to turn on the operation switch 71 and the housing 12 moves relative to the skin. The control circuit 70 controls the intermittent irradiation of the irradiation device 40 in such a manner that the irradiation area of ​​the skin is repeatedly irradiated by the light of one flash of the irradiation device 40 in the nth intermittent irradiation and the n+1th intermittent irradiation based on the movement amount and movement direction of the housing 12 detected by the movement amount sensor 50 and the size of the irradiation window 46.

[0080] like Figure 1 As shown, when the irradiation window 46 is a rectangle with a longitudinal dimension of H mm and a lateral dimension of W mm, the control circuit 70 controls so that when the movement direction of the housing 12 relative to the skin is along the longitudinal direction of the irradiation window 46, the irradiation device 40 performs intermittent irradiation every time the housing 12 moves H / x (mm), and when the movement direction of the housing 12 relative to the skin is along the lateral direction of the irradiation window 46, the irradiation device 40 performs intermittent irradiation every time the housing 12 moves W / x (mm). Wherein, x is an integer.

[0081] Under the control of the control circuit 70, the irradiation device 40 starts intermittent irradiation when the touch sensor 52 detects that the skin is in contact with the front surface of the front wall portion 24A, and the operation switch 71 is turned on by pressing the operation button 78, and the movement sensor 50 detects that the shell 12 is moving relative to the skin.

[0082] Turning on the operation switch 71 by pressing the operation button 78 is one of the conditions for starting intermittent irradiation by the irradiation device 40 , and thus the irradiation device 40 does not start intermittent irradiation against the user's intention.

[0083] The irradiation area of ​​the skin by one irradiation of the irradiation device 40 is determined by the size of the irradiation window 46 having a longitudinal dimension of Hmm and a lateral dimension of Wmm. Under this condition, when the movement direction of the housing 12 relative to the skin is along the longitudinal direction of the irradiation window 46, the irradiation device 40 performs intermittent irradiation every time the housing 12 moves H / x (mm), or when the movement direction is along the lateral direction of the irradiation window 46, the irradiation device 40 performs intermittent irradiation every time the housing 12 moves W / x (mm), so that each irradiation of the irradiation device 40 is repeated on the same area of ​​the skin.

[0084] Thus, the same repeated irradiation is performed in any case of the longitudinal movement and the lateral movement of the housing 12 relative to the skin. As a result, even if the irradiation energy of the irradiation device 40 is small at one time, it is possible to achieve an appropriate skin beautification effect uniformly and identically over a wide range while ensuring excellent safety, regardless of the longitudinal movement and the lateral movement of the housing 12 relative to the skin.

[0085] In the skin beautification device 10 of this embodiment, compared with the case where the desired skin beautification effect is obtained through a single irradiation, the irradiation energy of the irradiation device 40 can be reduced each time, and the user can easily and appropriately adjust the degree of irradiation to the skin based on repeated irradiations while observing the status.

[0086] The description of the specific embodiment has been completed above, but the present invention is not limited to the above-mentioned embodiment and modified examples, and can be implemented in a wide range of modifications.
