Referring to FIG. 5 again, this is a schematic view of the assembly of the sensor 45 and the bracket 46 of the diaper state monitoring device according to the embodiment of the present invention. When the sensor 45 and the bracket 46 are to be assembled and fixed, the front projection 66 of the sensor 45 can be inserted into the gap below the elastic soft rubber 65, and then the rear projection 68 of the sensor 45 is pressed downward. The sensor 45 is locked by sliding it under the rear hook 62 of the bracket 46. If the sensor 45 is to be removed from the bracket 46, the release button 67 of the bracket 46 can be pressed to open the rear hook portion 62 of the bracket 46, so that the sensor 45 can be removed from the bracket 46.

Fig. 6 is a perspective view showing the structure of the bracket 46 of the diaper state monitoring device according to the embodiment of the present invention, which facilitates further observation of the structure of the bracket 46 from different angles.

Fig. 7 is a perspective view showing the structure of a sensor 45 of the diaper state monitoring device according to the embodiment of the present invention. The sensor 45 is provided with two sets of

conductive contacts

71, 72 on the side opposite to the end of the front hook portion 61. Each set of conductive contacts includes a minimum of two conductive pins (each set of conductive contacts includes three conductive pins). It is used for electrical connection with the

sensing wires

82, 83 of the diaper, and transmits the sensing signal of the diaper to the sensor 45, thereby realizing the state monitoring of the diaper, which will be further described in the related drawings below. In order to reliably electrically connect the diaper sensing wires, the conductive pins are made of metal, and each of the conductive pins includes a sharp tip. In order to prevent the sharp tip from sticking, a protruding anti-baffle edge 75 is also included around the conductive contact/conductive pin to protect the sharp tip of the conductive contact.

Further, as shown in FIG. 8, this is a partial side cross-sectional view of the diaper state monitoring device of the embodiment of the present invention when used in conjunction with a diaper. In the figure, the bracket 46 is directly adhered to the front web 15 of the diaper by a Velcro (or adhesive) 55 attached to the bottom of the bracket. In this sense, the bottom of the bracket of the embodiment of the present invention includes a Velcro or a backing. . Below the front web sticker 15, the outer PE film 13 of the diaper is included, the

diaper sensing lines

82, 83 are included under the PE film 13, and the inner layer non-woven fabric 17 of the diaper is at the bottom, and the

sensing lines

82, 83 It is covered by the diaper outer layer PE film 13 and the inner layer nonwoven fabric 17, and has no contact with the user's skin.

When the diaper condition monitoring device of the embodiment of the present invention is used, the sensor holder 46 is first pasted on the front web sticker 15 of the diaper, and then the portion of the diaper 10 including the

sensing wires

82, 83 is overturned over the sensor holder 46. Above the elastic soft gel 65, the sensor 45 is finally assembled onto the bracket 46, so that the conductive contacts/

conductive pins

71, 72 on the sensor 45 (71, 72 can represent either conductive contacts or conductive contacts) The conductive needle) cooperates with the elastic soft rubber 65 on the bracket 46 to clamp the diaper and the corresponding induction wire, and the elastic force generated by the elastic soft rubber 65 causes the sharp tip on the

conductive needle

71, 72 to pierce through the diaper. The layer of nonwoven fabric 17 electrically connects the

electrical contacts

71, 72 to the

diaper sensing lines

82, 83 and transmits electrical signals of the sensing lines to the sensor 45 to effect condition monitoring of the diaper. The conductive pins 71, 72 seen in the figure include two sharp tips, and the conductive pin design with a plurality of sharp tips makes the contact with the sensing line more reliable because only one sharp tip is in contact with the sensing line. The electrical signal of the sensing line can be transmitted to the sensor to monitor the condition of the diaper.

Referring to FIG. 9 again, this is a functional block diagram of a diaper state monitoring device according to an embodiment of the present invention. The first sensing line 82 is electrically connected to the first group of conductive contacts 71. The first group of conductive contacts 71 further includes a first conductive pin 711 and a second conductive pin 712. The second sensing line 83 is electrically conductive with the second group. The contact 72 is electrically connected, and the third conductive pin 721 and the fourth conductive pin 722 are included in the second set of conductive contacts 72.

Clip sensing devices

713, 723 are also included in the

conductive contacts

71, 72, respectively. As can be seen from the foregoing description, when the sensor 45 is mounted on the bracket 46 and the edge of the trousers 10 is sandwiched between the bracket 46 and the sensor 45, the

conductive needles

71, 72 on the sensor 45 can contact the sensing line 82 of the diaper, 83 and electrically connected to it. Since the sensing line is electrically conductive, when two conductive pins of the same set of conductive contacts simultaneously contact the same sensing line, the resistance between the two conductive pins becomes very small. By detecting the resistance between the two conductive pins of the same set of conductive contacts, it can be known whether the conductive contact is electrically connected to the diaper sensing line, and thus whether the diaper is correctly sandwiched between the bracket and the sensor, thereby The "clip detection" function is realized (in the present embodiment, the diaper is also called a diaper, or simply "slice").

Since the first and second

conductive pins

711 and 712 and the third and fourth

conductive pins

721 and 722 are electrically connected to the

same sensing lines

82 and 83, respectively, the first and second conductive pins, and the first Third, the output of the fourth conductive pin is superimposed, so that the contact reliability is better, because each set of conductive contacts can input a signal from the sensing line as long as one conductive pin contacts the sensing line. The signal of the sensing line is transmitted to the capacitance detecting device 91 or the leakage detecting device 92. The capacitance detecting device 91 can detect the capacitance value of the electrochemical capacitor composed of the urine (electrolyte) between the first and second sensing lines and the sensing line, so that the quantitative urine level detection of the diaper can be realized. The leakage detecting device 92 can detect the leakage value between the two sensing lines, and can calculate the resistance between the first and second sensing lines, so that the urine state of the diaper and other diapers related to the leakage can also be known. status.

The outputs of the capacitance detecting device 91 and the leakage detecting device 92 are electrically connected to a microprocessor 93, and the microprocessor 93 processes and analyzes related data to obtain status data of the diaper, and the status data can be The status indication (for example, an audible and visual alarm) is performed by the status indicator 95, and can also be wirelessly transmitted by the wireless transmitter 96, thereby realizing the remote status monitoring function of the diaper.

It can be seen from the description of the above embodiments that the present invention has the beneficial effects that it fully utilizes the structural features of the diaper, realizes the diaper state monitoring function without being in contact with the user's skin, and is safe, reliable, convenient and practical. specialty.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and thus equivalent changes made in the claims of the present invention are still within the scope of the present invention.
