Description

[Detailed Description of the Invention] The present invention relates to a measurement probe for a permanent hair removal device for collecting basic data necessary for performing permanent hair removal.

2. Description of the Related Art Permanent hair removal devices are well known that perform permanent hair removal by applying electric energy such as direct current, high frequency, or other electromagnetic energy to the hair follicle of the hair to be removed. Such a permanent hair removal device can perform permanent hair removal relatively easily and reliably if handled appropriately. However, the hair removal treatment conditions vary widely depending on the gender and age of the person undergoing hair removal, the location of the body, and the timing of the hair cycle. Conventionally, the number of alkali units was introduced as a guideline for such processing conditions, and the output level, processing time, continuous or intermittent, etc. were determined according to this value.
A method has been adopted in which the moisture in the skin or hair follicle is measured and various treatment conditions are determined. In this way, the simple measurement method and the trial-and-error method of determining processing conditions based on several samplings rely on the intuition and experience of the processing engineer. There were particular problems.

SUMMARY OF THE INVENTION An object of the present invention is to provide a measurement probe for a permanent hair removal device that overcomes the drawbacks of the prior art and is suitable for a mechanism for easily and reliably determining hair removal treatment conditions.

The purpose of this is to integrate a glass electrode for measuring pH to measure the number of alkaline units in the area to undergo hair removal treatment, an electrode for measuring skin resistance to measure moisture, and a detection end for measuring skin temperature. This is achieved by a measuring probe of the permanent epilator placed at the tip of the case.

According to the measurement probe of the permanent hair removal device according to the present invention, it is possible to easily and quickly measure the data necessary for determining the treatment conditions of the area to be removed. As a result, even an inexperienced user can perform a reliable hair removal treatment without excess or deficiency.

Hereinafter, the present invention will be disclosed with reference to the accompanying drawings, which illustrate embodiments.

FIG. 1 is a perspective view showing the overall configuration of a measurement probe according to the present invention. The glass electrode 1 for measuring PH is a normal glass electrode that measures PH based on the membrane potential value generated when two liquids with different PHs come into contact with a thin glass membrane. Moisture measuring electrodes 2, 2 and a temperature measuring end 3 are arranged on the same surface of the glass electrode as the measuring part. These moisture measuring electrodes 2, 2
The temperature measuring end 3 is also integrally arranged at the tip of a suitable plastic holder 4 (see FIG. 2). An internal liquid replenishment port 5 is provided on the side surface of the glass electrode 1 for pH measurement. Furthermore, a cord 6 for a glass electrode for pH measurement and a cord 7 for moisture/temperature are provided at the base of the probe for connection to the main body (not shown).

FIG. 2 shows the state of the holder 4 from which the glass electrode for PH measurement has been removed. The portion 0 of the holder 4 is cut out, and it is convenient to construct the holder 4 so that the glass electrode 1 for pH measurement can be easily attached and detached as shown in FIG.

The PH, moisture, and temperature measured by the probe according to the present invention need to be measured in as narrow a range as possible of the hair removal area and corrected for each other. Therefore, as described above, each measuring section is constructed integrally, and is formed so that measurement can be performed by one contact with the region to be measured.

The glass electrode 1 for PH measurement is integrated into the holder 4 when in use, considering the convenience of maintenance, but it is convenient if it is made removable.

The moisture content of the area to be measured is measured from the resistivity of the skin between the two measurement electrodes 2, 2. Through this measurement, the moisture content is displayed in 5 to 10 levels, and processing conditions are determined based on the value.

The temperature of the site to be measured is measured using a thermocouple type or thermistor type temperature measuring element by bringing the end 3 into contact with the skin. In addition, when the glass electrode 1 for PH measurement has a built-in sensor for temperature compensation, its output can also be used as the temperature measurement output.

According to the measuring probe of the permanent hair removal device according to the present invention, it is extremely simple and easy to handle, and it is possible to accurately grasp the processing conditions without requiring special skill, achieving the intended purpose. be done.

Although disclosed based on advantageous embodiments of the present invention,
Obviously, many variations and modifications may be made within the scope of the invention.
