Will be deformed, and don't worry about bringing discomfort to the wearer. The sensing structure 16 is disposed at a position opposite to the front end portion 14a of the wing pin 14. Therefore, during treatment, the front end portion 14a-9-201249492 of the wing pin 14 is inserted and liquid such as blood or drip liquid is discharged from the body. When the vascular portion of the bulge leaks a little, it penetrates into a part or the whole of the absorbing member 20. The liquid metered by the one of the absorbing members 20 contacts the water battery 2 1, thereby acting as a catalyst, and the water battery 21 generates an electromotive force in the interior thereof to generate an electromotive force. With the generated electromotive force, current flows through the connector 17 to the notifying machine 18, and the notification machine 18 operates and beeps. In this way, the sensing structure 16 detects the leakage of the liquid and notifies the outside of the notification device 18, so that it is possible to prevent a medical accident or the like due to leakage of the liquid. Further, the sensing structure 16 has a function of detecting a liquid leakage or the like as a sensor, and also has a function as a power supply source for operating the notification device 18, and includes a base circuit or a semiconductor element as compared with the prior art. The automatic liquid detecting device (system) of a precision machine is very simple and inexpensive, and it is not necessary to supply power from the outside, so it is not necessary to worry about electric shock or electric leakage, and it is very safe. As shown in FIGS. 4 to 6, the water battery 21 has an upper surface 22A and a lower surface 22B, and includes: one thin plate-shaped positive electrode plate 23; two thin plate-shaped negative electrode plates 24 having substantially the same shape and size as the positive electrode plate 23, and The positive electrode active material 26 is filled inside the bag-like portion 25a of the cover sheet 25 formed of a liquid-permeable fibrous nonwoven fabric or a liquid-permeable plastic film. The positive electrode plate 23 is made of a metal having a high conductivity, a small ionization tendency, and a relatively stable electrochemistry, for example, a metal such as nickel, copper or silver, or an alloy mainly composed of these metals. The negative electrode plate 24 is made of an electrode active material having a large ionization and/or oxidation tendency, for example, metal magnesium, aluminum, zinc, or the like, -10-201249492, or an alloy containing at least two or more of these metals. The positive electrode active material 26 is in the form of a powder, and is fixed to the inner surface of the bag portion 25a of the cover sheet 25 via an adhesive applied in a spray form, and is strongly oxidized by a strong oxidizing substance such as activated carbon or dioxide. A mixture of manganese, iron oxide, crystalline silver oxide, or the like, and the kind or mixture ratio of the mixture can be freely set in accordance with the required oxidizing power. Further, in order to reduce the thickness of the water battery 21, various powders such as activated carbon may be formed into a sheet shape, and then fixed to the inner surface of the bag portion 25a via an adhesive. In the combined state of the water battery 21, the positive electrode plate 23 is inserted into the inside of the positive electrode active material 26, and each negative electrode plate 24 abuts against the upper and lower surfaces 2 2A, 22B of the pocket portion 25a of the cover sheet 25 to be sandwiched from the upper and lower sides. The bag portion 25a is placed in such a manner as to be placed. A portion of the extending portion 25b that extends continuously from the pocket portion 25a of the wrapping sheet 25 is folded back along a bending line 30 that is half-length along the width direction thereof, and the inner portion 31 abuts to be disposed in the pocket portion. On the upper negative electrode plate 24 of 25a, the outer portion 32 abuts against the negative electrode plate 24 disposed under the pocket portion 25a. As a result, the constituent members are wrapped in a stacked state to form the water battery 21 by the extending portion 25b of the covering sheet 25. The water battery 2 1 is formed by intermittently applying an adhesive so that the opposite faces of the cover sheets 25 overlapping each other, and the cover sheet 25 and the negative electrode plate 24 are joined to each other while sandwiching the whole body, The laminated state is maintained by a rigid plastic or metal fixing member 35 that bends both side portions 35a' to 35b. Further, although not shown, the side portion 35a of one side of the fixing member 35 is inserted into the through hole formed in one of the covering sheets 25, and is bent at -11 - 201249492, whereby even the water is externally The application of the impact by the battery 21 can also prevent the fixing member 35 from falling off from the water battery 21 without paying attention. As shown in Fig. 4, the water battery 21, in its internal configuration, since the negative electrode plate 24 and the positive electrode plate 23 are from above The lower portions 22A and 22B are alternately arranged toward the center thereof, and the electrochemical area is wider than that of the case where one negative electrode plate 24 and one positive electrode plate 23 are formed, and electricity can be generated more easily. That is, the distance between the negative electrode plate 24 on the upper surface 22A side of the water battery 21 and the positive electrode plate 23, and the distance between the negative electrode plate 24 and the positive electrode plate 23 on the lower surface 22B side are substantially the same, because The electrode plates 23 and 24 are filled with the positive electrode active material 26, so that an average electromotive force is generated in the thickness direction of the water battery 21. Therefore, the entire positive electrode active material 26 is not wasted, and the power generation action can be utilized. Referring again to FIGS. 2 to 3, the first connector 19A of the connector 17 has a substantially triangular shape and includes the first connector terminals 41a and 41b. The pair of protective sheets 43 are covered from the upper and lower sides, and the first connector terminals 41a and 41b are respectively connected to a pair of wires housed in the electric wires 40 extending from the water battery 2 1 . On one side of the protective sheet 43, a pair of slightly circular through holes 45 are formed. The first connector terminal (positive electrode) 41a has a male snap shape having a convex cylindrical engaging portion that protrudes from the through hole 45, and the first connector terminal (negative electrode) 41b has an engaging hole at the center thereof. The female snap shape is exposed from the through hole 45 of the protective sheet 43 respectively. The notification machine 18 has a second connector 19B made of cloth or plastic having an open end 50a, and a slightly rectangular outer casing 51 housed inside. The outer casing -12-201249492 has a body 51a on which a plurality of electric components are disposed, and a lid body 51b fitted along the outer periphery of the body 513. A portion of the body 51a and the lid body 51b is notched, and the rod 53a of the switch 53 is protruded from the opening formed by the notches. The second connector 19B is formed with an opening 54' formed therein for buzzing the buzzer and communicating with the through hole of the cover 51b of the outer casing 51. A pair of circular openings are formed in the second connector 19 B at the open end 50 a side of the opening 5 4 , and a through-wire 47 and a notification machine are fixed at the peripheral edge portion of the inner surface side of the opening. The second connector terminal (positive electrode) 48a connected to the internal circuit of 18, and the second connector terminal (negative electrode) 48b. The second connector terminal 48a has a male snap shape having a convex cylindrical engaging portion that protrudes from the opening, and the second connector terminal 48b has a female snap shape having an engaging hole at a center thereof. These are exposed from the openings of the second connector 19B, respectively. The first connector terminals 41a and 41b and the second connector terminals 48a and 48b having the associated shapes are respectively paired with each other, and the first connector terminal (positive electrode) 41a and the second connector terminal are respectively made ( The negative electrode) 48b, the first connector terminal 41b (negative electrode) and the second connector terminal (positive electrode) 48a are snap-fitted, the water battery 21 and the notification device 18 are electrically connected, and the liquid detecting device 10 is energized. In this way, the sensing structure 16 and the notification device 1 8 can be reliably connected by the simple operation of the snap-fit engagement, and the connectors can be connected to each other via other fixing members or via connectors such as sockets and adapters. When the means are connected, the operability is better. Then, after the liquid detecting device 1 is used, the vehicle can be re-used by simply removing the relevant snap-fit from the notification machine 18 and exchanging and discarding it, so that it can be quickly used. It is an exchange action and can minimize costs and is very economical. As shown in Fig. 7, in the inside of the main body 51a of the casing 51, a printed circuit board 55 is disposed, and the printed circuit board 55 has a booster circuit unit that can boost the voltage supplied from the water battery 21 to a required voltage. 56. A sounding unit 57 composed of a buzzer. The booster circuit unit 56 includes a boosting vibration transformer (reverse drive transformer) 60 connected to the connector terminal 41a (positive electrode) of the DC power source of the water battery 21, and a MOSFET or a bipolar NPN type power for vibration drive. The crystal 161 is connected to the base biasing impedance element 62 and the capacitor 63 which are connected in parallel between the transformer 60 and the transistor 61, and the diode 65 for rectifying the boosted voltage. The transformer 60 has a primary winding line and a secondary winding line (not shown). The primary winding is to wind the enameled wire having a wire diameter of about 1515 mm to the right on the core (ring coil) 50 times (inductance coefficient) It is formed by about 22 to 3 3 μΗ. The secondary winding line is formed by winding the enameled wire having a wire diameter of about 0.2 mm to the left 20 times on the core, and the ratio of the number of windings of the primary winding to the secondary winding is 2.5. As the impedance line for forming the primary winding and the secondary winding, in addition to the enameled wire or the nickel wire used in the general coil, a large electrical resistance can be used, for example, iron, copper-nickel alloy, copper-manganese alloy, iron-nickel alloy, A stainless steel wire or the like is wound on the secondary winding line of the transformer 60, and a 3.3 Ω impedance element 62 and a capacitor 61 of about 0.1 pF are connected in parallel, and the impedance element 62 and the capacitor 63 are connected to the base terminal of the transistor 61. Further, the -14 - 201249492 collector of the transistor 61 is connected to the primary winding of the transformer 60, and the transmitting terminal is connected to the negative terminal of the DC power supply. The boosting operation of the boosting circuit unit 56 will be briefly described. First, the switch 53 is turned ON, that is, according to the DC power supply, the secondary winding of the transformer 60 and the impedance element 62 are applied to the base terminal of the transistor 61. A base bias voltage is applied, and a base current flows between the substrate and a source. By applying the base bias voltage, the transistor 61 is turned ON, and the current also flows to the primary side winding of the transformer 60. According to the inrush current generated at this time, the magnetic field on the one-side winding line changes, and the pulse on the secondary winding line forms an inductive electromotive force. By the generated pulse, the input voltage is generated in the reverse direction, and on the secondary winding line, a volume ratio corresponding to the primary side winding line and the secondary side winding line is generated, and the input voltage is applied to the primary side winding line. Several times to dozens of times the induced voltage. By the pulse of the induced voltage, the base bias voltage drops, reducing the base current. As the base current decreases, the collector current decreases and the collector voltage increases. When the amplitude of the amplified collector voltage is low, the induced electromotive force is generated again on the secondary winding line, and by repeating these operations, the positive feedback vibration state of the boosting pulse is maintained. In the notification machine 18 having the related structure, the switch 53 is turned ON by the slide lever 53a, the water battery 21 and the notification machine 18 are energized, and when the liquid is supplied to the electrode of the water battery 2 1 to generate an electromotive force, The voltage circuit portion 5 6 is boosted to the required intensity so that the buzzer of the sounding portion 57 operates to generate a buzzer sound. In the related booster circuit, the power consumption for driving it can be reduced by using only the minimum required power and electronic components, and compared with the -15-201249492 voltage circuit using a plurality of power and electronic components, With a simple and inexpensive construction, it can be said that the cost is more advantageous. Further, since the circuit itself has a relatively fine size, it is suitable for use in a small machine similar to the notification machine 18 of the present embodiment. Further, the electromotive force generated by the electrochemical reaction of the water battery 21 according to the present invention is about 1.5 V, and as long as the electromotive force of the intensity is obtained, the buzzer sound of the sounding portion 57 can be operated without using a booster circuit (about 〇 The power of 〇4 5 W can be used for 20 hours), but the notification machine 18 is not limited to the use of the sounding unit 57, and has a light-emitting portion composed of a plurality of light-emitting diodes, or has vibration by a motor. In the case of the vibrator function, in order to activate these, it is necessary to have an electromotive force of about 5.0 V or more. Therefore, in the above case, it is necessary to use the above-described booster circuit 56. <Second Embodiment> Fig. 8 is a perspective view of a liquid detecting device 1A similar to Fig. 2 in the second embodiment, and Fig. 9 is a second connection of the first connector 19A and the notification device 18 of the second embodiment.
