Specifically, the electrical signal sensing unit 210 applied to the present invention comprises two electrodes 211 spaced a predetermined distance to contact the skin, and when the two electrodes contact the skin surface, the skin moisture Changes in electrical resistance or electrical impedance according to

The force sensing unit 220 closely adheres the hollow probe unit 240 to the skin with an external force, and at this time, determines the hardness of the skin from the force transmitted through the elastic body 221. For example, when the skin is hard, the hollow probe unit 240 goes deep into the body portion 100 and the elastic body is compressed a lot, so the strength is increased. On the contrary, if the skin is not relatively hard, the hollow probe does not go deep and the elastic body Since it is only slightly compressed, the force sensed by the force sensor is relatively small.

The humidity sensing unit 230 measures the amount of moisture emitted from the skin by continuously measuring the humidity inside the hollow probe unit 240 when the hollow probe unit 240 is in close contact with the skin surface.

2 and 3, these electrical signal detection units 210, force detection units 220 and humidity detection units 230 may be located inside the body unit 100.

Of course, if the signal of each detection unit is transmitted to the controller 300 in a wireless manner, it is obvious that the cable through hole 121 of the separate cable 140 and the side blocking wall 120 may be omitted.

The cap portion 130 is detachably coupled to the side blocking wall 120, and may be combined, for example, by a male and female screw fastening method, but is not limited thereto. An opening 131 is provided at the center of the cap 130, and more specifically, the inner diameter of the opening 131 is preferably smaller than the outer diameter of the hollow probe 240 and will be described later in this regard.

On the other hand, the cross section of the body portion 100 is preferably cylindrical or polygonal.

Subsequently, while the upper surface 241 and the side surface 242 are closed inside the body part 100, the lower surface is open, and the hollow probe part 240 of the upper light narrowing structure is gradually reduced in diameter as it goes downward. ) Is further provided.

The electrical signal detection unit 210 is provided at the lower end of the side surface 242 of the hollow probe unit 240 so that when the hollow probe unit 240 moves vertically, it comes into contact with the measurement site of the skin. The humidity sensing unit 230 measures the humidity inside the hollow probe unit 240, that is, humidity due to moisture emitted from the skin. The humidity sensing unit 230 may include a humidity sensing sensor 231 and a support 232 supporting the humidity sensing sensor 231, the upper surface 241 and the side surface 242 of the hollow probe unit 240 It is located inside the space sealed by). And the support 232 for supporting the humidity sensor 231 penetrates the side 242 to protrude a predetermined length into the space portion inside the body portion 100 and outside the hollow probe portion 240. Of course, it is obvious that the opening of the side through which the support 232 penetrates should be sealed so that the inflow and outflow of moisture can be blocked.

The force sensing unit 220 is fixed between the upper surface blocking wall 110 and the hollow probe unit 240 of the body portion 100, more specifically, one side is fixed to the upper surface blocking wall 110 and the other side is a hollow probe unit ( 240) Located on the top surface (241). In addition, between the force sensing unit 220 and the hollow probe unit 240, the elastic body 221, more specifically, one side is in contact with the force sensing unit 220, and the other side is outside the upper surface 241 of the hollow probe unit 240. The connected elastic body 221 is located.

Here, the elastic body 221 is not particularly limited as long as the hollow probe portion 240 can be contracted upon contact with the skin and then contracted to expand when removed, but may be, for example, a spring, rubber, or memory foam, preferably It is spring.

Meanwhile, the cap portion 130 performs a stopper function so that the hollow probe portion 240 connected to the elastic body 221 does not protrude beyond the body portion 100 more than necessary. That is, if the inner diameter of the opening 131 of the cap portion 130 is smaller than the outer diameter of the hollow probe portion 240, even if the elastic body 221 is provided on the hollow probe portion 240, only a predetermined portion protrudes.

The hollow probe portion 240 may be formed of a cylinder having a same inner diameter at the upper and lower portions, a rectangular pillar, or the like, but is preferably made of an upper and lower strait structure that gradually narrows as the side 242 goes downward. This is because it is more accurate to target a small area in measuring the skin hardness, and furthermore, the stopper function is enabled only by adjusting the inner diameter of the opening 131 of the cap 130.

4 is a cross-sectional view of a skin analysis device according to a first modified embodiment of the present invention. In the skin analysis device of the type according to the first modified embodiment of FIG. 4, except for the positions of the elastic body 221 and the force sensing unit 220, it is substantially the same as the skin analysis device described with reference to FIGS. 1 to 3 or similar. Therefore, the same components are denoted by the same reference numerals, and repeated descriptions of the same components will be omitted.

5 is a cross-sectional view of a skin analysis device according to a second modified embodiment of the present invention, and FIG. 6 is an enlarged view of a probe pin. In the skin analysis device according to the first modified embodiment of FIG. 5, the electrical analysis device 210 is substantially the same or similar to the skin analysis device described with reference to FIGS. 1 to 3 except for the electrical signal detection unit 210. Therefore, the same components are denoted by the same reference numerals, and repeated descriptions of the same components will be omitted.

In the skin analysis apparatus according to the second modified embodiment of the present invention, the electrical signal detection unit 210 is provided on the side surface 242 of the hollow probe unit 240, and the probe pin is stretchable according to whether it is in contact with the skin. (212).

Specifically, as shown in Figure 6, the probe pin 212 is an elongated cylindrical sleeve 212a, one side is fixed to the sleeve 212a, the other side is a free elastic member 212b, and one side is the elastic member 212b ) Can be configured to include a contact pin 212c having a predetermined length that is fixed to the other side of the free and the other side protrudes out of the sleeve 212a.

Here, one side of the contact pin 212c directly in contact with the skin is preferably conical, similar to a top, because it can easily contact the skin at various angles.

On the other hand, in FIG. 5, the probe pin 212 is illustrated as being coupled to the outside of the side 242 of the hollow probe 240, but is not limited thereto, for example, the side 242 inside or side 242. It may be inserted into and fixed.

Here, the probe pin has the advantage of being able to maintain a constant contact with the skin because it has elasticity by itself. That is, in case of employing a probe having no elasticity, if the probe protrudes too much, it may cause pain when it comes in contact with the skin. If the probe protrudes too little, the electrical signal is not measured or the measurement value changes significantly, resulting in an accurate measurement. Since there is a problem that cannot be achieved, a probe pin including an elastic member 212b is preferable as in the present invention.
