Skin therapy device

Abstract

The skin therapy device combines the mechanical stimulation and cleansing in the form of vibration with optical stimulation from LEDs. The device combines these two elements without sacrificing the effectiveness of either the mechanical cleansing/stimulation or optical stimulation by passing the light through the mechanical elements that are in contact with the skin. The light from the LEDs does not pass around the mechanical elements, such as around opaque brush fibers, but passes through the mechanical elements.

DETAILED DESCRIPTION

[0034] Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.

[0035] Referring to FIG. 1, a first isometric view of the skin therapy device is shown.

[0036] The skin therapy device 1 includes primary components of body 10 and silicone head 90. The silicone head 90 is shown in two embodiments cleansing head 92 and massaging head 94. Both types of silicone head 90 affix to the protective cover 80 (see FIG. 2), differing primarily in the type and shape of protrusions. The cleansing head 92 includes many smaller protrusions for a scrubbing action, the massaging head 94 includes fewer, larger protrusions for a gentler interaction with the skin.

[0037] The silicone head 90 is preferably formed from a flexible material that is stretched, or rolled, over the protective cover 80.

[0038] Referring to FIGS. 2 and 3, a first cross-sectional view, and a second, partially-exploded, cross-sectional view, of the skin therapy device are shown.

[0039] The body 10 of the skin therapy device 1 is formed from an outer skin 12 and an inner shell 20. In the preferred embodiment, the outer skin 12 is a softer material, such as silicone, and the inner shell 20 is a more rigid, structural material such as metal or stiff plastic.

[0040] The outer skin 12 includes a locking rim 14 that fits into a locking ledge 22 of the inner shell, holding the layers together.

[0041] Within the body is one or more battery 29, held in place by battery support 30.

[0042] A motor bracket 38 is affixed to the inner shell 20, holding motor 34 that spins an unbalanced weight 36 to create vibration. The vibration is passed through the inner shell 20, to the locking plate 70, to the protective cover 80, and finally to the silicone head 90.

[0043] A locking plate 70 joins the protective cover 80 to the body 10, holding the LED circuit board 58 within the protective cover 80 and against the inner shell 20.

[0044] The LED emitters 52 are placed beneath the LED circuit board 58 where they can emit light through the protective cover 80 and the silicone head 90.

[0045] The protective cover 80 includes a locking slot 86 with a first locking section 88 and a second locking section 89. The locking plate 70 interfaces with the locking slot 86, resting at the first locking section 88. The inner shell 20 also interfaces with the locking slot 86, resting at the second locking section 89. Thus, each locking slot 86 connects the locking plate 70 to the inner shell 20, holding the skin therapy device 1 together.

[0046] The protective cover 80 is formed from wall 82 and face 84.

[0047] Referring to FIG. 4, an exploded view of the base and head, with LEDs, of the skin therapy device is shown.

[0048] The skin therapy device 1 simultaneously emits therapeutic light, while also massaging or abrading the skin.

[0049] This is accomplished by allowing light to shine through the lower elements of the device, while protecting the electronics from contact with water, skin oils, and so forth.

[0050] The LED circuit board 58 includes LED emitters 52 that emit light at one or more wavelengths. For example, light at wavelength one 60 and light at wavelength two 62.

[0051] The light 60/62 passes through the optically transparent protective cover 80 and through the optically transparent silicone head 90, reaching the user's skin below.

[0052] In the preferred embodiment, there are no holes in the protective cover 80 or silicone head 90 to allow light 60/62 to pass. Rather, the LED emitters 52 are physically isolated from the user's skin below, the light passing through to reach the skin.

[0053] Referring to FIGS. 5 and 6, a first cutaway view and a second cutaway view the skin therapy device are shown.

[0054] The skin therapy device 1 is divided into the body 10 and the base 50. The body 10 includes a circuit board 28 with power button 32, mounted to a battery case 30.

[0055] Within the battery case 30 are batteries 29. The batteries are shown as single-use AAA batteries, but any type of battery power is anticipated. For example, lithium-ion batteries, nickel-metal hydride batteries, and so forth.

[0056] The motor 34 with unbalanced weight 36 is also shown, serving as a source of vibration. Alternative sources of vibration include linear resonant actuators.

[0057] Referring to FIGS. 7 and 8, a third cutaway view, and an exploded view of the base and head, showing the locking features, of the skin therapy device are shown.

[0058] The locking plate 70 includes two or more plate tabs 72 that interface with the protective cover 80 via the locking slot 86. The plate tabs rest in the first locking section 88 because the locking plate is inserted into the protective cover 80 before the protective cover 80 is attached to the inner shell 20.

[0059] The locking slot 86 further include a second locking section 89 that interfaces with the shell tabs 24 (see FIGS. 8 and 9) of the inner shell 20.

[0060] The shell tabs 24 nest within the plate gap 73 of the locking plate 70.

[0061] The locking plate further includes battery through-holes 74 for supporting the battery jumper plate 31 (see FIG. 9).

[0062] Also shown is the silicone head 90 with cleansing head 92.

[0063] Referring to FIGS. 9 and 10, a first and second exploded view showing all parts of the skin therapy device is shown.

[0064] The skin therapy device 1 includes body 10 formed from an inner shell 20 with outer skin 12, the inner shell 20 including a locking ledge 22 to attach the inner shell 20 to the outer skin 12.

[0065] Within the body 10 is a battery case 30 with battery jumper plate 31 on the locking plate 70.

[0066] A power button 32 operates the skin therapy device 1.

[0067] Motor 34 with unbalanced weight 36 attaches to the inner shell 20 via motor bracket 38.

[0068] The locking plate 70 holds the LED circuit board 58 in place within the protective cover 80, the silicone head 90 fitting over the protective cover 80.

[0069] Referring to FIG. 11, a first alternative exterior shape for the skin therapy device is shown.

[0070] The skin therapy device 1 includes a base 50 and body 10. The outer skin 12 is shown with a geometric shape.

[0071] Referring to FIG. 12, a second alternative exterior shape for the skin therapy device is shown.

[0072] The skin therapy device 1 includes a base 50 and body 10. The body 10 is elongated, creating a large grip for a user. The power button 32 is on the lower section of the grip, where a user's fingers will sit.

[0073] Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.

[0074] It is believed that the system and method as described and many of its attendant advantages will be understood by the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction, and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely exemplary and explanatory embodiment thereof. It is the intention of the following claims to encompass and include such changes.
