Description

Integrated beuty care apparatus

The present invention relates to a cosmetic device, and more particularly, to a portable cosmetic treatment device incorporating some therapeutic and diagnostic functions related to beauty. The present invention also relates to a battery pack for a mobile communication terminal in which such a beauty treatment apparatus is implemented, and a mobile communication terminal including the battery pack.

Ultrasonic beauty devices are known in the context of skin care. The device utilizes a piezoelectric transducer (PZT) oscillator that vibrates mechanically at frequencies around 1 MHz. Such vibrations penetrate up to 6 cm subcutaneously to transfer energy, enhancing metabolism, improving fine lines, suppressing aging, and skin. It is known to have the effect of whitening.

The circuit of the conventional ultrasonic beauty machine is that of the patent application published by Matsushita Denko Co., Ltd. and published in Japanese Patent Application Publication No. 1999-0023482 published on March 25, 1999. This circuit vibrates the ultrasonic vibrator by the pulse oscillation circuit, and measures the resistance of the vibrator itself to detect whether the vibrator is in contact with the skin and to increase the vibration only when contacted, thereby causing the vibrator by unnecessary vibration when exposed to the air. Is to prevent overheating. In addition, the registered publication of Utility Model No. 217,393 filed and registered by Digital Eco Co., Ltd. discloses a portable ultrasonic beauty machine in which a plurality of vibrators of the ultrasonic beauty machine are configured to increase efficiency. In this device, a plurality of vibrators are connected to the same drive circuit in the same manner, and additionally employ a thermistor which detects heat generation of the vibrator by temperature to detect skin contact.

In addition, low-frequency treatments, which have recently gained popularity in relation to diets, are known to exert low-frequency electric vibrations on the skin to smooth the nervous system and blood circulation, thus eliminating the need for muscle mass removal.

Patent No. 1996-14098, filed by Hwang Hyun Bae et al., Filed Oct. 14, 1996, describes a skin care device having such a function. When the microcomputer outputs a pulse signal to the low frequency output terminal according to the input signal of the keypad, the low frequency signal is applied to the skin surface through a pad connected to the output terminal, and the pulse waveform or the output level can be adjusted.

Those who are interested in beauty and health want all of these devices, but in the past, such devices exist as separate devices, so it is inconvenient for each user to have them. The present inventors have been researching for a long time to integrate and easily carry them when the interest in the ultrasonic beauty device or low frequency treatment device is increasing. Because such beauty treatments must be available anytime and anywhere, it is very important to carry them in women's handbags or men's bags.

The inventors further noted that integrating these devices is very advantageous in terms of cost and portability.

Furthermore, the present inventors have made the idea of integrating such a function into a mobile communication terminal which has been widely spread in recent years. In this process, in order to add such a function without significantly changing the hardware of the mobile communication terminal itself, the study was intended to embed the necessary hardware in the battery pack detachably coupled to the mobile communication terminal.

The idea of embedding additional optional circuits in the battery pack is not new. Japanese Patent Laid-Open No. 9-270836, published October 14, 1997, discloses an additional device implemented with a radio circuit embedded in a battery pack detachably coupled to a mobile communication terminal. In addition, Korean Patent Application Publication No. 2001-19664 filed by Kim Tae-jin and published March 15, 2001, includes an MP3 codec and a flash memory module in a battery pack of a mobile communication terminal, and controls audio using a user interface of the mobile communication terminal.
