Description

A temperature-displaying and humidity-measuring feeding bottle

technical field

The utility model relates to an infant feeding bottle, in particular to a temperature-displaying and humidity-measuring feeding bottle with the functions of temperature measurement and air humidity measurement.

Background technique

Traditional baby bottles cannot know the temperature of the liquid in the bottle, so adults usually use hand-touching and mouth-testing methods when feeding infants and young children. These methods accuracy and sanitation are all very poor, because adult has very big difference with infant to temperature sensitivity and adaptability, and germ and bacterium in adult's oral cavity all can cause the pollution to drink in the feeding bottle.

Although there are many baby bottle temperature measurement patents and many of them have been transformed into production, there are still many defects. The existing baby bottle temperature measurement technology can be divided into three categories: one is to use a temperature-sensitive probe to extend into the bottle body for temperature measurement; The temperature is measured on the outside of the bottle wall. Most of the existing temperature-measuring feeding bottles on the market adopt the open structure of the bottom of the bottle body, the purpose of which is to facilitate cleaning after the bottle body is separated from the temperature-measuring base. However, after repeated disassembly and assembly, it will be difficult to avoid the wear and aging of the joints between the bottle body and the temperature measuring base, and the milk will flow out along these joints. Due to the open bottom, it is difficult to completely overcome the shortcoming of milk leakage. Leakage of the milk will damage the circuit board of the temperature measuring device; it will also pollute the milk on the temperature measuring and humidity measuring circuit board, thereby posing a threat to the health of infants and young children.

At the same time, the humidity of the air is closely related to the health of children. If the humidity is too high, it will easily cause the overgrowth of certain bacteria; if the humidity is too low, the air will be too dry, which will cause the baby's skin to be too dry, and even cause Japanese encephalitis. . Therefore, temperature and humidity are the two most common factors affecting the health of babies. On the other hand, because the hygrosistor used for electronic temperature and humidity measurement and the thermistor used for temperature measurement have matching characteristics in working principle, so , the two can be compatible in one IC chip and circuit board, so that the cost performance of the product is greatly improved, and the product cost is greatly reduced.

Utility model content

The purpose of the utility model is to overcome the defects of the prior art, and provide a temperature-displaying and humidity-measuring feeding bottle that is simple in structure, convenient to use, safe and reliable, and can accurately measure and display milk temperature, air temperature and air humidity.

The purpose of this utility model is achieved in this way: a temperature-displaying and humidity-measuring feeding bottle, which includes two parts: a feeding bottle and an electronic temperature-measuring and humidity-measuring base, wherein the feeding bottle includes a nipple, a bottle cap and a bottle body, and is characterized in that: the bottom of the bottle body A heat conductor made of a material with good thermal conductivity is embedded, but the bottom of the bottle body is a closed structure, and an electronic temperature and humidity measurement base is connected to the bottom of the bottle body to display the liquid temperature and air humidity in the bottle. The temperature and humidity measurement base is a structure that is independent of each other but can be used together. The electronic temperature and humidity measurement base includes a base shell, an intelligent temperature and humidity measurement circuit, a temperature sensor, and a humidity sensor. A circuit control panel and The display screen, the temperature sensor is closely attached to the bottom of the bottle body, and the humidity sensor is in contact with the air through the through hole on the surface of the base.

The temperature sensor is closely attached to the bottom of the bottle body through elastic components. Such as the use of elastic steel sheets, coil springs and other components.

In order to make the temperature and humidity measuring bottle have a temperature and humidity reminder function, the electronic temperature and humidity measurement base also includes a temperature and humidity reminder device. The temperature and humidity reminder device is a horn, a buzzer, a light-emitting diode or a vibrator. The temperature and humidity measuring circuit includes a temperature and humidity reminder circuit. The user can set the reminder temperature or reminder humidity through the circuit control panel. When the temperature becomes the reminder temperature or reminder humidity, the reminder circuit starts the reminder device to generate a reminder signal. For example, the speaker can play beautiful music, and the light-emitting diodes can produce lights of different colors. Bright, the vibrator also makes the bottle vibrate.

The utility model also includes a portable handle, which is composed of a collar in the middle and handles on both sides. An annular protrusion is arranged at the lower part of the bottle mouth, and the collar of the portable handle is embedded and fixed in the annular protrusion at the lower part of the bottle mouth. from within. The inner sides of the handles on both sides of the portable handle have protrusions, which can improve the hand feel, increase friction, and are not easy to fall off during use.

The utility model also includes a dust cover, the edge of the lower mouth of the dust cover has a ring protruding inwardly, and the outer periphery of the bottle cap has a stepped structure with a small outer diameter on the upper part and a larger outer diameter on the lower part. There is a ring-shaped groove in the bottle cap. When the dust cover is covered, the ring protruding inward from the edge of the lower mouth is embedded in the ring-shaped groove of the bottle cap. This structure allows the dust cover to be fastened to the top of the bottle.

The height of the dust-proof cover is slightly lower than that of the pacifier, and the dust-proof cover slightly presses the opening of the pacifier, so that the liquid in the bottle is slightly inclined or inverted instantly, and the liquid in the bottle will not flow out.

The bottom surface of the housing of the base for measuring temperature and humidity is an upward concave surface, on which there are cooling holes and a fulcrum protruding downward. This structural design is conducive to dissipating the heat and water vapor generated by the temperature measurement and humidity measurement circuit. At the same time, even if there is liquid flowing out on the plane where the baby bottle is placed, it will not flow into the heat dissipation vent hole of the base, thereby protecting the electronic module from damage. erosion.

Described thermistor selects NTC thermistor (being negative temperature coefficient thermistor) for use, its resistance value of NTC thermistor presents stepwise reduction along with the rising of NTC thermistor body temperature, temperature The higher the value, the smaller the resistance value. Since the resistance value of the thermistor changes with temperature, the microprocessor can convert the measured resistance change value into a temperature value and display it on the liquid display screen.

The humidity resistance is formed by superficially spraying a layer of polymer moisture-sensitive film on a special insulating substrate. When the water vapor in the air is adsorbed on the moisture-sensitive film, the resistivity and resistance value of the element will change, and the microprocessor will convert the measured resistance change value into a humidity value and output it to the liquid crystal display.

Compared with the prior art, the utility model embodiment has the following advantages:

First of all, the bottom of the bottle is completely closed, and the body of the bottle and the base for measuring temperature and humidity are independent of each other, avoiding the potential risk of leakage and pollution of the traditional induction probe temperature measuring bottle. When there is leftover milk that has been cooled, the bottle body can be removed from the base and directly placed in hot water or a heater for heating, which is very convenient.

Secondly, the temperature measurement test base uses only a temperature and humidity measurement circuit and a temperature and humidity reminder device. A circuit control panel and a temperature and humidity display are set on the base. The reminder temperature value and the reminder humidity value can be set through the control panel. The temperature display screen can display the instant temperature of the milk and the reminder temperature, and can also display the air humidity. The temperature and humidity reminder device can be a horn, a buzzer, a light-emitting diode or a vibrator. When the temperature or humidity changes to remind the temperature or remind the humidity, such as the horn can play wonderful music, the light-emitting diode can produce light of different colors, and the vibrator can also make the bottle body vibrate.

Thirdly, the temperature measuring and humidity measuring base has two important functions of temperature measuring and displaying temperature and humidity measuring and displaying humidity at the same time, and is compatible with a common set of electronic systems, so that this product can simultaneously measure and display milk temperature, air temperature, air humidity and temperature Humidity alarm function, compared with products that realize the above functions separately, consumes less resources and lowers costs, bringing real benefits to consumers.

Finally, the bottle body and the base shell are reasonable in design, beautiful in appearance, easy to use, safe and reliable, and are an ideal feeding bottle for displaying temperature and humidity.
