Technical Field
The utility model belongs to the technical field of infant articles for use, more specifically say, relate to a type detection device that infant's bottle was suckleing or water.
Background
Most parents of infants can feed milk or water to the infants in a feeding bottle feeding mode. Infants have scientific requirements on the amount of milk or water fed each time, time interval and total amount fed each day at different ages. A professional doctor usually requires a parent to record the daily feeding amount and feeding time of an infant, so that the parent can feed the infant quantitatively on time, and the data can be recorded for the professional doctor to evaluate the growth and development conditions of the infant. In the traditional feeding mode, parents manually record the time and feeding amount of each feeding and estimate the time point of the next feeding. Manual recording is prone to cause inaccurate metering, missing or lost recorded data, difficulty in forming statistical data of recorded information, inconvenience for parents and trouble for analysis of professional doctors. At present, some intelligent milk bottle type products are available in the market, and are used for measuring parameters such as time for feeding infants, feeding amount and the like.
Many parents use a single bottle for both feeding milk and water at different times.

Detailed Description
The following description of the present invention will be provided in conjunction with the accompanying drawings to enable those skilled in the art to better understand the present invention. It is to be expressly noted that in the following description, detailed descriptions of known functions and designs will be omitted when they may obscure the main contents of the present invention.
Fig. 1 is a schematic structural view of a specific embodiment of the device for detecting the type of milk or water fed to an infant bottle of the present invention.
In this embodiment, as shown in fig. 1, the device for detecting the type of feeding or water in an infant bottle of the present invention includes an infrared emitter 1, an infrared receiver 2, a determination module 3, an infrared light-transmitting housing 4 and a circuit board 5. The infrared transmitter 1, the infrared receiver 2 and the judgment module 3 are arranged on the circuit board 5.
As shown in fig. 1 and 2, the infrared emitter 1 emits infrared light toward the transparent or translucent bottle-feeding container 6, and reflects the infrared light back when encountering milk or water contained in the bottle-feeding container 6. The reflected infrared light is received by the infrared receiver 2 and converted into an infrared light intensity value, which is transmitted to the determination module 3. The judgment module 3 receives the infrared light intensity value from the infrared receiver, compares the infrared light intensity value with a set threshold value, and if the infrared light intensity value is larger than the set threshold value, the liquid contained in the bottle-feeding container 6 is considered to be milk, otherwise, the liquid contained in the bottle-feeding container 6 is considered to be water.
In this embodiment, the infrared emitter 1, infrared receiver 2, and determination module 3 are sealed by an infrared transparent enclosure 4 on the top, so that the bottle feeding container 6 can be placed on top, and the infrared transparent enclosure 4 functions to transmit infrared light and protect the internal circuitry.
In a specific implementation process, the infrared transmitter, the infrared receiver and the judgment module may be separate devices, or two of them may be integrated in the same device, or all three may be integrated in the same device.
The bottle-feeding container is a container made of transparent or semitransparent materials, and comprises a feeding bottle, a water cup and the like. The bottle feeding container can be a stand-alone container or a component embedded in a product and having a function of containing liquid.
The infant bottle feeding or water type detection device can be realized in a product independent from the bottle feeding container, or can be integrated with the bottle feeding container into a product.
The judgment module can be realized by adopting a central processing unit (MCU), and an acquisition port is used for acquiring, comparing and judging the infrared light intensity value of the infrared receiver; the method can also be implemented by adopting a circuit mode of discrete components, for example, the threshold value is a certain voltage value, the voltage comparator is used for comparing the voltage value with the collected infrared light intensity value, the output 1 is milk (the infrared light intensity value is greater than the threshold value), and the output 0 is water (the infrared light intensity value is less than or equal to the threshold value). The method is realized by adopting a central processing unit (MCU), is more convenient and flexible, and has the same judgment mechanism no matter the method is realized by adopting the central processing unit (MCU) or a circuit of a discrete component.
In this embodiment, the infrared light is emitted to a transparent or translucent bottle-feeding container (such as a feeding bottle or a cup) within a certain distance by a central processing unit (MCU), and after the infrared light reaches the surface of the bottle-feeding container, the reflectivity of the infrared light on the surface of the bottle-feeding container is different due to the difference between the transparency and the refractive index of the milk or water contained in the bottle-feeding container. Under the same condition, the intensity of the infrared light reflected back when the bottle feeding container contains milk is far greater than the intensity of the infrared light reflected back when the container contains water, and a central processing unit (MCU) can judge whether the bottle feeding container contains milk or water by collecting the intensity value of the infrared light received by an infrared receiver and comparing the intensity value with a set threshold value.
In this embodiment, the infrared light emitting step is: the central processing unit (MCU) controls the infrared emitter to emit infrared light with certain wavelength and intensity to the container. The infrared light may be emitted continuously or in multiple pulses to reduce power consumption, and the actual power of the infrared emission may be adjusted based on the actual product structure, housing material, and distance from the infrared emitter and receiver to the container.
In this embodiment, the infrared light receiving step includes: a part of infrared light emitted by the infrared emitter is reflected to the infrared receiver by the bottle feeding container, is converted into an electric signal (a light signal is converted into an electric signal) by an infrared photosensitive device in the infrared receiver, and is sampled into a digital signal, namely an infrared light intensity value, by an analog-to-digital conversion circuit (ADC) in the infrared receiver or an analog-to-digital conversion circuit (ADC) in a central processing unit (MCU). For the infrared light emitted in the form of a plurality of pulses, the integral operation can be carried out on the infrared light intensity values collected for many times in a central processing unit (MCU), the infrared light intensity value which is finally compared with the threshold value is obtained, and the measurement sensitivity is increased.
In this embodiment, the determining step is: when the liquid in the bottle-feeding container is milk, the infrared light reflected by the bottle-feeding container is stronger because the transmissivity of the milk is lower; however, when the liquid contained in the bottle-feeding container is water, the infrared energy is substantially transmitted through the water due to the high transmissivity of the water, and the infrared light reflected by the bottle-feeding container is weak. The central processing unit (MCU) compares the detected infrared light intensity value with a set threshold value, and judges that the infrared light intensity value is higher than the threshold value; otherwise, the water is judged. In this embodiment, the area value of the measurement statistic of the infrared light intensity values reflected by milk and water near the middle is selected as the threshold value through multiple actual measurement results.
The utility model discloses go deep into to excavate the demand of feeding the mode more scientific, healthy, convenient to the infant, distinguish the infant automatically and feed the type that the in-process fed milk or water to make the head of a family and professional child-care doctor or mechanism can acquire more accurate data of feeding.
