Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Referring to fig. 1 and 2, the present invention provides a diaper sensor, which includes a controller 11, a first conductive strip 12, a second conductive strip 13, a first conductive probe 15, a second conductive probe 16, and a clamping mechanism 17. The first conductive strip 12 and the second conductive strip 13 are used for being buried in the paper diaper 14, the first conductive probe 15 and the second conductive probe 16 are connected with the controller 11, the first conductive probe 15 and the second conductive probe 16 are arranged on the clamping mechanism 17, the clamping mechanism 17 is used for clamping the first conductive strip 12 and the second conductive strip 13, and when the first conductive strip 12 and the second conductive strip 13 are clamped, the first conductive probe 15 and the second conductive probe 16 are respectively contacted with the first conductive strip 12 and the second conductive strip 13.

The first conductive strip 12 and the second conductive strip 13 are disposed in the paper diaper 14 at intervals, and when urine wets the area between the first conductive strip 12 and the second conductive strip 13, the first conductive probe 15 and the second conductive probe 16 are conducted.

Specifically, the first conductive probe 15 and the second conductive probe 16 are respectively connected to two different pins on the controller 11. Accordingly, the controller 11 can determine whether the first conductive probe 15 and the second conductive probe 16 are in communication by determining whether the two pins are in communication, thereby determining whether the paper diaper 14 is wet with urine.

In addition, most of the electronic components in the conventional diaper sensor are disposed in the diaper 14. The lifetime of these electronic components may be affected during repeated use. In the embodiment of the present invention, urine only contacts the first conductive strip 12 and the second conductive strip 13, and the above-mentioned problem does not exist.

Further, the first conductive probe 15 and the second conductive probe 16 are respectively clung to the first conductive strip 12 and the second conductive strip 13 through the clamping mechanism 17, so that the technical problem of poor contact between the conductive probe and the conductive strip caused by body movement of a user in the process of wearing the diaper is avoided.

In some embodiments, as shown in fig. 3, 4 and 5, the clamping mechanism 17 includes a clamp cover 171 and a face cover 172. The clamping cover 171 and the face cover 172 are in cover connection, the first conductive probe 15 and the second conductive probe 16 are arranged on one surface of the face cover 172 facing the clamping cover 171, and the clamping cover 171 and the face cover 172 are used for clamping the first conductive strip 12 and the second conductive strip 13.

When the paper diaper sensor is used, the paper diaper provided with the first conductive strips 12 and the second conductive strips 13 is placed on the surface cover 172, and then the clamp cover 171 and the surface cover 172 are covered, so that the first conductive strips 12 and the second conductive strips 13 are respectively abutted against the first conductive probes 15 and the second conductive probes 16, and good contact between the first conductive strips and the second conductive probes is ensured.

In other embodiments, the clamping mechanism 17 further includes a rear cover 173, where the front cover 172 and the rear cover 173 are fixed together to form a receiving space 1731, and the controller 11 is received in the receiving space 1731. The rear cover 173 can cover the controller 11 to seal the accommodating space 1731 to prevent dust from entering, thereby achieving the purpose of sealing and protecting the same.

Further, the cover 172 is provided with a first probe hole 1721 and a second probe hole 1722, one end of the first conductive probe 15 and one end of the second conductive probe 16 respectively extend into the accommodating space 1731 to be electrically connected with the controller 11, and the other end of the first conductive probe 15 and the other end of the second conductive probe 16 respectively pass through the first probe hole 1721 and the second probe hole 1722 to protrude out of the surface of the cover 172 facing the clamp cover 171, when the clamp cover 171 and the cover 172 are in cover connection, the first conductive strip 12 and the second conductive strip 13 are fixed on the cover 172 in a contact manner, and the first conductive strip 12 and the second conductive strip 13 respectively contact with one ends of the first conductive probe 15 and the second conductive probe 16. The first probe hole 1721 and the second probe hole 1722 can be communicated with the accommodating space 1731, so that the first conductive probe 15 and the second conductive probe 16 can be conveniently connected with the controller 11. Of course, it should be noted that the number of the first probe holes 1721 and the second probe holes 1722 are the same as the number of the first conductive probes 15 and the second conductive probes 16, respectively, and are in one-to-one correspondence.

Further, as shown in fig. 6, the cover 172 is provided with a cover sink 1723, the first conductive probe 15 and the second conductive probe 16 are both located in the cover sink 1723, and the cover 171 can be covered in the cover sink 1723. Of course, it is understood that the cover plate 1723 includes a bottom surface and a side surface as shown in fig. 6, and further, the first probe hole 1721 and the second probe hole 1722 may be provided on the bottom surface of the cover plate 1723, thereby facilitating assembly of the first conductive probe 15 and the second conductive probe 16 with the cover plate 1723.

It should be noted that: if the cover plate 1723 is not provided, the cover plate 171 is protruded to the cover plate 172 when being covered, so that the cover plate 171 is easily touched by foreign objects to the wall surface thereof, thereby causing rotation thereof, and thus the cover plate 172 is separated, resulting in poor contact. When the cover 171 is covered on the cover sink 1723, the cover 171 needs to be inserted into the cover sink 1723 to rotate out the cover 171, so that the cover 171 is not easy to rotate out due to accidental touching. In addition, when the clip cover 171 abuts against the wall surface of the cover mount 1723 during rotation of the clip cover 171, the clip cover 171 cannot rotate with respect to the cover any more, thereby restricting the angle of rotation of the clip cover 171 with respect to the cover and preventing the angle of rotation from becoming excessively large. In some embodiments, the height of the clip cover 171 and the height of the cover sink 1723 may be set to be the same, so that after the clip cover 171 is covered on the cover sink 1723, the clip cover 171 just blends into the cover, thereby ensuring the integration of the appearance shape of the diaper sensor, making the shape more round and beautiful, and facilitating the diaper not to go.

In other embodiments, as shown in fig. 5 and 7, one end of the cover 171 is rotatably connected to a surface of the cover 172 facing away from the rear cover 173, one end of the cover 171 is rotatably connected with a protruding fastening table 1715, a side wall of the cover sink 1723 is provided with a fastening slot 1726, and the cover 171 can be rotated until the fastening table 1715 is received in the fastening slot 1726, so as to achieve the cover connection between the cover 171 and the cover 172. When the diaper sensor is needed, the cover 172 is turned and opened, the first conductive probe 15 and the second conductive probe 16 are placed in corresponding positions, then the clamp cover 171 is turned and closed, the buckling table 1715 is accommodated in the buckling groove 1726, the clamp cover 171 and the cover 172 are covered, the first conductive probe 15 and the second conductive probe 16 are clamped, and the purpose that the first conductive probe 15 and the second conductive probe 16 are respectively clung to the first conductive strip 12 and the second conductive strip 13 is achieved. When the diaper 14 needs to be replaced, the cover 171 may be rotated again to separate the cover 171 from the cover 172, so that the diaper 14 may be replaced.

When the cover 171 is covered in the cover sink 1723, the fastening device 1715 extends into the fastening groove 1726, and the fastening groove 1726 limits the fastening device 1715, so as to fix the cover 171 on the cover sink 1723. Of course, in other embodiments, the same fixing effect may be used to fix the clip cover 171 and the cover sink 1723, which will not be described in detail herein.

Further, because the knob 1715 is located at an end of the cover 171 remote from the connection where the cover 171 is pivotally connected to the cover 172, the knob 1715 edges are chamfered, which facilitates guiding the knob 1715 in a depressing action and does not damage the knob 1715 itself.

In some embodiments, the clamping cover 171 and the face cover 172 may be connected by a rotation shaft 174 to achieve rotational connection, as shown in fig. 4, 6 and 7, the clamping mechanism 17 further includes a rotation shaft 174, the clamping cover 171 is provided with a hinge groove 1711 and a cover shaft hole 1712 disposed on a side wall of the hinge groove 1711, the face cover 172 is provided with a hinge boss 1724 and a cover shaft hole 1725 penetrating the hinge boss 1724, the hinge boss 1724 is disposed on a side wall of the face cover sink 1723, the hinge boss 1724 is accommodated in the hinge groove 1711, one end of the rotation shaft 174 passes through the cover shaft hole 1725 and is inserted into the cover shaft hole 1712, the other end of the rotation shaft 174 is disposed on the clamping cover 171, and the clamping cover 171 may rotate relative to the face cover 172 with the rotation shaft 174 as an axis.

When the cover 171 needs to be closed or opened, the cover 171 is rotated, and the other end of the rotating shaft 174 is disposed on the cover 171, so that the rotating shaft 174 will also rotate, and the cover 172 will remain relatively stationary, and at the same time, the cover shaft hole 1725 can limit the freedom of the rotating shaft 174, so as to prevent the cover 171 from being separated from the cover 172, because the rotating shaft 174 passes through the cover shaft hole 1725. In addition, during the process of opening the clamping cover 171, the hinge groove 1711 will abut against the side wall of the cover sinking table 1723, so as to limit the rotation angle of the clamping cover 171.

Of course, in other embodiments, a device with the same connection effect may be used to implement the rotational connection between the clip cover 171 and the face cover 172, which will not be described herein.

Further, the clip cover 171 is further provided with a side groove 1713, and the other end of the rotation shaft 174 is accommodated in the side groove 1713. The side groove 1713 serves to limit the degree of freedom of the rotation shaft 174, preventing rotation of itself, ensuring that the rotation shaft 174 rotates only when the clip cover 171 rotates.

Further, the clip cover 171 is further provided with a return groove 1714, the other end of the rotating shaft 174 is extended with a return hook 1741, and the return hook 1741 is in interference fit with the return groove 1714. This prevents the rotation shaft 174 from being separated from the cover 171, and realizes fixation between the rotation shaft 174 and the cover 171. Of course, in other embodiments, the loop-shaped groove 1714 and the loop-shaped hook 1741 may be other devices for achieving the same fixing effect, which will not be described herein.

Further, the cover 171 is provided with a first clearance area 1716 and a second clearance area 1717, between the side groove 1713 and the hinge boss 1724, the second clearance area 1717 is located between the hinge boss 1724 and one end of the hinge groove 1711 where the cover shaft hole 1712 is provided, and the first clearance area 1716 is located between the other end of the hinge groove 1711 and the hinge boss 1724. Specifically, first void region 1716 may be located between side groove 1713 and hinge boss 1724.

When the cover 171 is covered, the buckling platform 1715 will first contact the edge of the cover sink 1723, the buckling platform 1715 is continuously pressed down, the rotating shaft 174 starts to elastically deform and moves backward in the first clearance area 1716 and the second clearance area 1717, the cover 171 moves backward due to the interference fit between the rotating shaft 174 and the cover 171, the buckling platform 1715 can move down to reach the buckling groove 1726 against the wall surface of the cover sink 1723, and the rotating shaft 174 will resume deformation due to no wall surface against the cover 171 at the position of the buckling groove 1726, so that the buckling platform 1715 is pressed into the buckling groove 1726, and the fixation between the cover 171 and the cover sink 1723 is realized.

In some embodiments, as shown in fig. 3 and 5, the clamping mechanism 17 further includes a dust cap 175, and the face cap 172 further includes a positioning groove 1727, where the dust cap 175 is attached to the positioning groove 1727 for covering the buckling groove 1726. This prevents dust from entering the receiving space 1731 from the catching groove 1726 when the clip cover 171 is opened, thereby affecting the circuit elements of the controller 11.

In other embodiments, as shown in fig. 4 and 5, the clamping mechanism 17 further includes a soft rubber pad 176, and the soft rubber pad 176 is attached to a surface of the clamping cover 171 facing the face cover 172. The flexible rubber pad 176 may cover the loop-shaped hook 1741 of the shaft 174, further limiting the rotation of the shaft 174 itself. Meanwhile, the structure inside the back mold of the clamp cover can be covered, so that the structure is tidier and more attractive. The soft rubber pad 176 has good elasticity and friction force, can not damage the paper diaper 14, can better clamp the paper diaper 14, and more importantly, ensures that the first conductive probe 15 and the second conductive probe 16 are respectively and fully contacted with the first conductive strip 12 and the second conductive strip 13.

In other embodiments, as shown in fig. 1 and 2, the diaper sensor further includes an indication module 18, where the indication module 18 is connected to the controller 11; the number of the first conductive probes 15 is two, the two first conductive probes 15 are arranged on the first conductive strip 12 at intervals, the number of the second conductive probes 16 is two, the two second conductive probes 16 are arranged on the second conductive strip 13 at intervals, the controller 11 is used for detecting whether the two first conductive probes 15 are conducted or not and whether the two second conductive probes 16 are conducted or not, and when the two first conductive probes 15 are conducted and the two second conductive probes 16 are also conducted, the control indication module 18 outputs a good contact indication, otherwise, the control indication module 18 outputs a bad contact indication.

Alternatively, the indication module 18 may be an indication lamp, and when the two first conductive probes 15 are turned on and the two second conductive probes 16 are also turned on, the indication lamp is turned on to indicate good contact, and if not, the indication lamp is turned on to indicate bad contact. Of course, it is also possible to use two indicator lamps to respectively display whether the first conductive probe 15 and the second conductive probe 16 are in good contact, or the indicator module 18 is a display module, and the display module is used to display the contact condition between the first conductive probe 15 and the second conductive probe 16, and the indicator module 18 is used to indicate the contact condition between the first conductive probe 15 and the second conductive probe 16 and the first conductive probe 15 and the second conductive probe 16, so that a user can conveniently and timely know whether the contact condition between the first conductive probe 15 and the second conductive probe 16 and the first conductive probe 15 and the second conductive probe 16 is good, and when the contact condition is bad, the adjustment is possible, so that the situation that the controller 11 cannot detect whether urine exists on the diaper 14 due to poor contact after the diaper 14 is worn can be avoided.

In other embodiments, as shown in fig. 5, the diaper sensor further includes a battery box 19 and a battery 20, the battery 20 is installed in the battery box 19, the battery box 19 is accommodated in the accommodating space 1731, the battery box 19 is connected to the rear cover 172 in a drawable manner, and the battery 20 is connected to the controller 11 for supplying power to the controller 11. Of course, the battery 20 also supplies power to other power consuming components of the diaper sensor. In other embodiments, as shown in fig. 7, the diaper sensor further includes a wireless communication module 21, and the wireless communication module 21 is connected to the controller 11. The wireless communication module 21 can connect the controller 11 with the mobile terminal through bluetooth or WiFi, and transmit information of whether the diaper is wet by urine or not to the terminal device.

It should be noted that: the battery box 19 may be connected to the rear cover 172 in a retractable manner by using a conventional technique, such as a retractable battery compartment mechanism.

In the embodiment of the invention, the first conductive probe 15 and the second conductive probe 16 are respectively clung to the first conductive strip 12 and the second conductive strip 13 in the paper diaper 14 through the clamping mechanism 17, so that the problem of poor contact is avoided. In addition, the first conductive strip 12 and the second conductive strip 13 are contacted with urine to detect whether urine exists in the paper diaper 14, and other electronic components of the invention are not contacted with the urine, so that the service life of the electronic components is longer than that of the prior art.

Referring to fig. 8, the present invention further provides a urine detection method.

FIG. 8 is a flow chart of an embodiment of a method for urine detection according to the present invention. As shown in fig. 1, the method is applied to a diaper and comprises the following steps:

step S101: and detecting whether the first conducting strip and the second conducting strip are arranged in the paper diaper at intervals. If yes, step S102 is executed, and if no, step S101 is continued.

In the step, the first conductive strip and the second conductive strip are fixed on the paper diaper in a printing technology or a magic tape mode, and when the paper diaper is wet by urine, the urine permeates the interval area between the first conductive strip and the second conductive strip, so that the first conductive strip and the second conductive strip are conducted. Of course, the controller for detecting whether it switches on can set up in the marginal one end of panty-shape diapers, and when the user urinates, the polymer water-absorbent resin in the panty-shape diapers absorbs the urine for the urine that the user output can only wet the wet region of urine, and urine can not flow to the marginal position of panty-shape diapers, leads to soaking above-mentioned controller. Therefore, the method can detect urine without adverse effect on the controller.

When the first conducting strip and the second conducting strip are not conducted all the time, the fact that the diaper is free of urine wet is indicated, and the user does not urinate.

It will be appreciated that: the distance between the first and second conductive strips is not preferably set too wide to avoid too little urine to completely wet the area between them. Of course, different widths may be set according to different target users of the diaper, for example: infants, who generally urinate less at a time, may be provided with a slightly smaller width between the first and second conductive strips, and adults, who generally urinate more at a time, may be provided with a wider width between the first and second conductive strips.

Step S102: and determining that urine exists in the paper diaper.

When the first conductive strip and the second conductive strip are conducted, the user is indicated to urinate, and the paper diaper is indicated to urinate.

Different from the situation of the prior art, the embodiment of the invention determines whether urine exists in the paper diaper by detecting whether the first conducting strip and the second conducting strip which are arranged in the paper diaper at intervals are conducted or not, so that the detection of the urine in the paper diaper is realized. In addition, other electronic components for detecting urine except the first conductive strip and the second conductive strip can be arranged in the paper diaper, cannot be soaked by urine, and is beneficial to prolonging the service lives of other electronic components.

Referring to fig. 9, fig. 9 is a flowchart of a urine detection method according to another embodiment of the invention, which is different from the above embodiment in that, after step S102, the method further includes:

step S201, obtaining the impedance between the first conductive strip and the second conductive strip.

When the area between the first and second conductive strips is not wet with urine, the impedance can be regarded as infinite as being insulating between the paper diaper and the fibrous material of the paper diaper, since these are non-conductive. When urine wets the area between them, first conducting bar and second conducting bar are conducted, and it forms a loop with controller, so that the controller can judge the magnitude of impedance between them according to the magnitude of inflow current.

And step S202, determining the urine volume on the diaper according to the impedance.

When more urine is present on the diaper, the more the humidity of the fibrous material in the region between the first and second conductive strips is, and thus the more conductive it is, the lower the impedance between the first and second conductive strips will be. Therefore, the linear relation between the impedance and the humidity can be obtained, when the controller reads the impedance, the humidity can be calculated through the linear relation between the impedance and the humidity which are set in the controller in advance, and the humidity can reflect the urine volume.

Referring to fig. 10, fig. 10 is a flowchart of a urine detection method according to another embodiment of the invention, which is different from the above embodiment in that, after step S202, the method further includes:

step S301: determining whether the urine volume exceeds a threshold. If yes, go to step S302, if no, no alarm information is output.

Because the adsorption capacity of the paper diaper is limited, when urine is too much, the upper limit of the adsorption capacity of the paper diaper is reached, and the urine which is not adsorbed can contact the human body, so that discomfort or infection of the human body is caused, whether the urine volume is too much or not is required to be judged, and when the urine volume is too much, the paper diaper is prompted to be replaced.

Step S302: and outputting alarm information.

The alarm information is used for reminding the replacement of the paper diaper. The mode of outputting alarm information can be a finger lamp alarm or a sound alarm, or the alarm information is output to other terminal equipment through a wireless communication module, so that a holder of the terminal equipment can replace paper diapers of users in time

Referring to fig. 11, fig. 11 is a flowchart of a urine detection method according to another embodiment of the invention, and the difference between the present embodiment and the above embodiment is that, after step S102, the method further includes:

And S401, acquiring the conduction times between the first conductive strip and the second conductive strip.

In step S102, the area between the first conductive strip and the second conductive strip is wetted by urine, so that conduction between the first conductive strip and the second conductive strip is performed. However, the moisture in the urine can be absorbed by the macromolecule water-absorbent resin in the paper diaper, and after the urine is dried, the conduction between the first conducting strip and the second conducting strip can be disconnected again, and when the diaper is soaked by the urine again, the conduction between the first conducting strip and the second conducting strip can be conducted again, so that the urination frequency of a user can be determined through the conduction frequency between the first conducting strip and the second conducting strip.

And step S402, determining the times of urination of the human body according to the conducted times.

Each time a conductive connection between the first conductive strip and the second conductive strip is made, the first conductive strip and the second conductive strip can be counted as urination. In addition, due to the high adsorptivity of the diaper, urine is absorbed by the polymer absorbent resin in the diaper immediately after wetting the region between the first conductive strip and the second conductive strip. Therefore, even if the interval between urination is extremely short, the process of turning on, off, and re-conduction can be completed between the first conductive strip and the second conductive strip.

During sleeping at night, a caretaker cannot replace the paper diaper in time, and a user of the paper diaper cannot control urination, so that the user can urinate on the paper diaper for many times at night. However, the specific urination times cannot be intuitively seen from the diaper, and the urination times can be determined through the conduction times between the first conductive strip and the second conductive strip, so that the health condition of a user can be further analyzed through the urination times.

The present invention provides an embodiment of a urine detection device, as shown in FIG. 12, which includes a detection module 501 and a first determination module 502.

The detection module 501 is configured to detect whether the first conductive strip and the second conductive strip are arranged in the diaper at intervals.

Further, the apparatus further comprises: a judgment module 505 and an output module 506.

A determination module 505 is configured to determine whether the urine volume exceeds a threshold.

And the output module 506 is used for outputting alarm information.

And the second obtaining module 507 is configured to obtain the number of times of conducting between the first conductive strip and the second conductive strip.

The specific structure and working principle of each module described above may refer to descriptions of corresponding steps in the method embodiment, and are not repeated here.

In the prior art, most of the urine detection methods adopt a humidity sensor to directly contact with urine to detect humidity, and then judge whether the urine exists according to a humidity value. In the method, the humidity sensor is required to be continuously contacted with urine in the use process, and the electronic elements in the humidity sensor can be influenced after repeated use. In the embodiment of the present invention, the detection module 501 detects whether the first conductive strip and the second conductive strip in the diaper are conductive. Wherein urine only contacts the first conductive strip and the second conductive strip, and the above problem does not exist. In addition, the number of times of conduction between the first conductive strip and the second conductive strip can be acquired through the second acquisition module 507, so that the urination number of the user can be determined, and the health condition of the user can be further analyzed.
