Description

FIELD OF THE INVENTION

The present invention relates generally to ultrasonic technology. More particularly, it relates to a novel ultrasonic skin care device with a built-in integrated skin-treatment specimen dispenser along with an electrical interface to enable easy application of the specimen for hygiene operation and skin beautification purposes.

BACKGROUND OF THE INVENTION

It has been well realized that ultrasonic technologies can be used in skin treatment and beautification. FIG. 1 is a schematic diagram shows illustrating a typical ultrasonic skin treatment device, the structure of which is commonly shared by all available products in the market. The device contains a device body 1, i.e. a handle or a casing, where resides electronics that controls an ultrasound transducer 3. The device body 1 may have other functions such as power control and charging which are not shown in FIG. 1. The device contains a vibration plate 2, which is usually metallic, that contacts human skin with its external surface 4 and is driven by the ultrasound transducer 3 which is coupled to the internal surface of the plate 2. The vibration at ultrasonic frequency from the transducer 3 is transmitted to the human skin or skin treatment products via the external surface 4. For easy handling, the plate 2 and the transducer 3 are enclosed in a housing, which is not shown in FIG. 1, of the device body 1.

In prior art devices, due to the design feature as FIG. 1 shows, skin treatment specimen is dispensed from a separate specimen container either directly to the skin surface or to the external surface 4 of the plate 2 before treatment on target skin area with simultaneous application of the ultrasound vibration from the plate 2. This process of application of skin treatment specimen from an external container limits the device's portability, where the specimen application from separate container not only increases the complexity of the skin treatment process but also imposes hygiene concerns if such skin treatment process is not to be performed in a dedicated area such as a beauty spa or a private room, but in a public area with frequent traffic such as office, public transportation or elevator. For daily beautification purpose, it is desired that such ultrasound treatment process can be extended into a typical user's day time, other than the usual limited time skin treatment process in the morning or at night, in order to benefit from the full scale that ultrasonic treatment can offer. Prior arts due to their limited portability and need of separate specimen containment, can not meet the stated treatment requirement because of the complexity of the application process.

What is desired is a new design ultrasonic device for generating ultrasound vibration and applying specimen concurrently, which is extremely portable and can relieve the user from the external specimen application process such that ultrasound treatment can be easily done at the time periods that are not usually feasible for using prior art designs.

SUMMARY OF THE INVENTION

The present application discloses and teaches a novel solution of utilizing an integrated specimen dispenser with electrical interface in ultrasonic skin treatment device and other electronic skin treatment devices. Methods to utilize the electrical interface to achieve easier and better skin beautification process are also disclosed.

It is an object of this invention to integrate a skin treatment specimen dispenser having an electrical interface with an ultrasonic vibration generation device to produce an ultra portable and hygiene solution to enable extended ultrasound treatment for daily skin beautification.

It is another object of this invention to integrate a skin treatment specimen dispenser having an electrical interface with an electronic skin treatment device.

Yet it is another object of this invention to provide possible methods to enhance portability, flexibility and customizability of skin treatment devices with integrated specimen dispenser having an electrical interface.

In a first embodiment of this invention, we described a skin-treatment specimen dispenser integrated within an ultrasonic massaging device, wherein the dispenser has an electrical interface that communicates with the control electronics of the massaging device.

We have also realized that the enhanced portability, flexibility and customizability by an integrated specimen dispenser with electrical interface can not only benefit ultrasound based skin treatment devices, but also benefit all electronic skin treatment devices that operate by acting on human skin with a physical touching such as vibration, brushing, abrasion, piercing, and optical lightening, etc. and with an externally applied skin treatment specimen such as liquid, gel, serum, cream, lotion, paste and powder.

In a second embodiment of this invention, we described a skin-treatment specimen dispenser integrated with an electronic skin treatment device, where the dispenser has an electrical interface that communicates with the control electronics of the skin-treatment device.
