Background

The traditional diaper or baby diaper can only absorb urine, but if the diaper is not replaced in time, the health of the baby can be affected if the baby is in a humid environment. Therefore, the prior diaper is often added with an active alarm function. The existing diaper is characterized in that the alarm is triggered by detecting the humidity of the crotch of the diaper, when a baby urinates, the electrode disconnected inside the sensor is switched on due to the urine, and an alarm circuit is triggered. The other is that an alarm circuit is triggered by detecting atmosphere, such as ammonia concentration, the alarm principle of the diaper is based on that ammonia is volatilized from urine after a baby urinates, and the alarm circuit is triggered when the ammonia concentration exceeds a set threshold value.

However, both diapers have the disadvantage that the first diaper alarms as long as the humidity of the local area where the sensor is located exceeds a predetermined range, which leads to frequent false alarms. For example, a false alarm may be given when the amount of perspiration locally is large. The second diaper is based on ammonia concentration to give an alarm, and when a plurality of babies are in the same space, the diaper can give an alarm when the ammonia concentration in the air nearby is increased due to the urination of other babies, so that the phenomenon of misinformation is caused.

Detailed Description

The present application will be described in further detail below with reference to the accompanying drawings by way of specific embodiments.

The present embodiment provides an alarm diaper, as shown in fig. 1 and 4, including: the diaper comprises a diaper body 1 and an alarm device fixed on the diaper body 1, wherein the alarm device comprises an alarm circuit 2 and a trigger device electrically connected with the alarm circuit 2. The triggering device is used for controlling the alarm circuit 2 to alarm and comprises a humidity sensor 3, an ammonia gas concentration sensor 4 and a controller 5 which is respectively and electrically connected with the humidity sensor 3 and the ammonia gas concentration sensor. When the humidity of the diaper and the ammonia concentration in the air are detected to reach the triggering conditions, namely the humidity and the ammonia concentration reach the threshold values, the controller 5 controls the alarm circuit 2 to be conducted.

As shown in fig. 2, the humidity sensor 3 employs two resistive humidity sensors 30 disposed in parallel at the crotch portion of the body. Each of the resistance type humidity sensors 30 includes two thin film printed electrodes spaced apart from each other, and one end thereof is electrically connected to one input terminal of the controller 5 at the waist portion of the body 1. When the wearer does not urinate, the resistance between the two thin film printed electrodes is regarded as infinite since the two thin film printed electrodes are not in contact with each other, and when the wearer urinates, the resistance between the two thin film printed electrodes is decreased due to the urine. Similarly, the ammonia gas concentration sensor 4 is electrically connected to the other input terminal of the controller 5. When one humidity sensor 3 detects that the humidity in the body 1 exceeds the preset humidity and the ammonia concentration sensor 4 detects that the ammonia concentration in the air is increased to exceed the preset concentration, the controller 5 controls the alarm circuit 2 to alarm. The control of the working state of the circuit by electrically connecting the controller 5 with the sensor is a mature technology, and its specific implementation means are many, for example, the controller is implemented by an and circuit, the and circuit has a plurality of inputs and an output, when the humidity sensor 3 at the input detects that the environment exceeds the predetermined humidity, the input contact of the controller 5 corresponding to the humidity sensor 3 presents a high level; when the ammonia concentration sensor 4 detects that the ammonia concentration in the environment exceeds the preset concentration, the controller 5 presents a high level with the corresponding input end contact, and if and only if the contact input connecting the two sensors is high level, the output end of the controller 5 outputs the high level, thereby controlling the alarm circuit to alarm.

As shown in fig. 3 and 4, the alarm diaper further comprises a wearing body 6, the wearing body 6 is fixed at the front waist part 11 of the body 1, the outside of the wearing body 6 is an elastic rubber skin, the inside of the wearing body is provided with a PCB (printed circuit board) 8, and the alarm circuit 2, the ammonia concentration sensor 4 and the controller 5 are packaged on the PCB 8.
