Abstract
The utility model relates to a feeding bottle. A temperature measure and display device is additionally arranged on the basis of an existing feeding bottle comprising a nipple, a bottle cap and a bottle body to form the feeding bottle of the utility model. A sensing temperature contact head used for measuring temperature is directly contacted with the outer wall of the bottle body. The voltage of a temperature signal is compared with a reference voltage, which can obtain a control signal used for controlling the passage way of an indicating light. The corresponding temperature can be displayed. The feeding bottle can display temperature. The utility model has the advantages of convenience, practicability, safety, sanitation and civilization. The feeding bottle of the utility model is an important necessary used for nursing infants.
Description
The present invention relates to the utensil that a kind of artificial suckling is used.
At present people buy the feeding bottle of use from market, mainly chew by milk, and bottle cap, bottle is formed, and perhaps also is shaped on the scale that shows liquid measure on bottle, also is added with a cover cap on bottleneck, but the temperature of milk in can not display bottle.Yet the milk liquid temp is vital to the baby, and the too high meeting of temperature causes mucosa scald in the baby oral cavity, crosses to hang down to cause the disorder of baby's gastrointestinal function.So during artificial suckling, the judgement way of custom is to adopt hands to touch or face subsides perception, this needs by rule of thumb, and even so error is also bigger.Also having the tongue of many humans oneself to go perception, though method more reliably, is easy to generate the cross infection of disease or pathogenic bacteria, is non-good plan.
Task of the present invention provides a kind of feeding bottle with temperature indicating device, and it can be avoided adopting said method and utilize display lamp to reflect the temperature of milk in the bottle objectively.
Technical scheme of the present invention is on the basis of existing common feeding bottle, being provided with one is connected with bottle contact, temperature indicating device that can be for convenience detach, temperature indicating device is by shell block and be contained in the temperature susceptibility contact terminal that contacts installation in the shell block with bottle, power supply, on and off switch, the temperature detection display circuit of a temperature indicator and a contact said elements is formed.
Can also realize the sound alarm if in foregoing circuit, add a sound alarm circuit of forming by acoustics circuit and loudspeaker,, carry out the preparation ， And of suckling and cause baby's trained reflex just on larger distance, can hear sound.
Device of the present invention transmits temperature by bottle, and temperature-sensitive is convenient, objective, health, accurately and reliably.Temperature error is ± 0.5 ℃.Set temperature indicator can demonstrate the situation that milk is in the different temperatures zone, observes intuitively, and easy to use.
The present invention is further illustrated below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is that the end of temperature indicating device is to cutaway view.
Fig. 3 is one of circuit diagram.
Fig. 4 is two of a circuit diagram.
The feeding bottle of band temperature indicating device shown in Figure 1, top be one by milk chew 1, bottle cap 3 bottles 4 and be located at the common feeding bottle that the cover cap 2 of bottle mouth position is formed.What of liquid measure in the bottle scale 10 on the bottle be used to refer to.The bottom is a temperature indicating device.Contact the thermistor element that the temperature susceptibility contact terminal of installing 6 adopts the sheet metal type with the bottle body bottom outer surface, the power supply packed cell, switch 7 control power paths, what temperature indicator adopted is light emitting diode, circuit is contained on the circuit board 8, above-mentioned component parts all is contained in the shell 5, and the bottom surface has bottom 9 to cover.
Fig. 2 represents the situation that is provided with of mutual alignment between each component parts of temperature indicating device.In the middle of circuit board 8 is inlaid in, the next door is a power supply 12(packed cell), the driving lever of switch 7 stretches out from the side of seat shell 5, temperature indicator 11(light emitting diode) position is consistent with the default fenestella of seat shell 5, has the aperture 14 that is used to transmit sound on the seat shell-side face of the installation site correspondence of piezoelectric loudspeaker 13.
