Description

Diaper alarm

Technical field

The present invention relates to a smart diaper, and more particularly to a diaper alarm for a smart diaper.

Background technique

The diaper according to the present invention generally refers to various paper diapers and diapers. Paper diapers and diapers have been used more and more because of their convenient use, and have become a daily necessities commonly used by infants and the elderly. However, the traditional diaper can not judge from the appearance whether the wearer has defecate, which is often observed by the caregiver, and often causes the wearer to be uncomfortable if the diaper is not changed in time. By providing a sensor in the diaper, an alert signal is issued to the caregiver after the wearer defecates, thereby overcoming the above problems.

Since the circuit portion (ie, diaper alarm, or communication trigger device) is costly, and the diaper is usually a disposable product, if the sensor and the circuit portion are integrated, the following defects exist: 1. If used once, the diaper is used together. If you throw it away, the cost is very high. 2. If it is removed from the diaper after use, it will be difficult to clean. In order to solve the above problems, the sensor and the circuit part can be designed in a split type, and the sensor and the circuit part are respectively attached to the surface of the diaper, and then the two are electrically connected by a detachable connection, so that the sensor with low price is the same as the diaper. Disposables, while the higher cost circuit parts can be reused.

However, since the diaper sensor is usually made of a cloth base or a paper base, it is relatively soft, and is generally band-shaped, has a very thin thickness (usually less than 1 mm), and is easily bent. If a conventional detachable connection method (such as plugging, etc.) is used, There are defects in connection difficulties and unreliable connections.

detailed description

The invention will now be further described with reference to the drawings and embodiments.

The construction of some embodiments of the diaper alarm is schematically illustrated in Figures 1-7. As shown in Figures 1-7, the diaper alarm of some embodiments includes a housing and a circuit board 3 mounted within the housing, and a connection mechanism for removably attaching the diaper sensor. The housing includes a plate body 1 having a receiving chamber 11 and a cover body 2. The mouth portion of the accommodating chamber 11 is provided on one plate surface of the plate body 1, and the lid body 2 is attached to the mouth portion of the accommodating chamber 11. The cover body 2 has a main cover 21 and a sub cover 23 which is formed on the first end 22 of the main cover 21 and foldable around the long side of the first end 22. The connecting mechanism includes a connecting electrode 31 disposed on the circuit board 3, and a long pin 24 disposed on a lower surface of the sub-lid 23 and a plurality of short pins 25. The connecting electrode 31 is below the sub-lid 23 and is opposite to the plurality of short pins 25. correspond. The connecting mechanism further includes a connecting hole 12 provided in the plate body 1 for receiving and holding the long pin 24.

When in use, the sub-cover 23 is turned over, a part of the accommodating cavity 11 is opened, the connecting electrode 31 is exposed, and one end of the diaper sensor is inserted into the accommodating cavity 11 so that the conductive connecting portions on the diaper sensor are covered one by one. On the connection electrode 31 on the circuit board 3, the sub cover 23 is reversely reversed, and the accommodating cavity 11 is closed. At this time, the short pin 25 on the sub cover 23 presses the conductive connection portion on the diaper sensor to the circuit board. The connection electrodes 31 on the 3 are reliably connected, and the long pins 24 on the sub-cover 23 are received and held by the connection holes 12 in the board body 1, thereby holding the sub-cover 23 in the closed state. When it is desired to separate the diaper alarm from the diaper sensor, the diaper sensor can be removed from the diaper alarm by simply flipping the sub-cover 23. It can be seen that the diaper sensor can be connected and detached with the diaper alarm conveniently, quickly and reliably.

Further, the circuit board 3 is provided with three connection electrodes 31, and the sub-cover 23 has three sets of short pins 25, specifically one short pin 25 on the left side in FIG. 5 is a group, and the two short pins 25 in the middle are a group. One short pin 25 on the right side is a group, and three sets of short pins 25 are in one-to-one correspondence with the three connection electrodes 31, so that the three connection electrodes 31 and the three conductive connection portions on the diaper sensor can be reliably connected. In this case, the diaper sensor has three detecting electrodes, which can detect not only whether the wearer has a bowel movement, but also distinguish between stool and urination.

Further, the sub-lid 23 is provided with two long pins 24 which are spaced apart from the three sets of short pins 25. This further ensures that the sub-lid 23 can be reliably locked in the closed state after being closed.

In some embodiments, the associated diaper sensor is provided with an auxiliary aperture through which the long pin 24 passes after the diaper sensor is attached to the diaper sensor. This can assist in the rapid positioning of the diaper sensor. For example, the diaper sensor can be positioned on the sub-cover 23 by using the auxiliary hole and the long pin 24, The sub-lid 23 is then closed, on the one hand the positioning of the electrically conductive connection on the diaper sensor and the connection electrode 31 on the circuit board 3 can be achieved, and on the other hand the displacement of the diaper sensor can be prevented.

Further, one end of the plate body 1 is provided with an elongated hole 13 through which the diaper sensor passes. When connected, the connecting end of the diaper sensor passes through the elongated hole 13 and extends into the accommodating cavity 11 to be connected to the connecting electrode 31 on the circuit board 3, through which the diaper sensor can be quickly positioned.

Furthermore, the rapid positioning of the diaper sensor can also be achieved by the width of the receiving chamber 11, in particular by adapting the width of the receiving chamber 11 to the width of the diaper sensor.

Further, the long pin 24 and the plurality of short pins 25 have elasticity.

The present invention has been described in detail with reference to the specific embodiments thereof, but these specific descriptions are not to be construed as limiting the scope of the invention, and other modifications or equivalents can be made by those skilled in the art in light of the description of the invention. Wait. The scope of the invention is defined by the claims.
