Simultaneously, the heat preservation holder has the advantages of small volume, light weight, low prices, excellent performance, and the like.

Description

The feeding bottle thermal insulating seat

Technical field

The utility model relates to infant's articles for daily use, especially a kind of feeding bottle thermal insulating seat.

Background technology

Feeding bottle is a kind of articles for daily use to Infantile nursing; this feeding bottle generally all comprises nipple, bottle cap and bottle; milk liquid is transferred and is converted after regular meeting runs into the situation that the baby does not temporarily eat; because common feeding bottle does not have heat insulation function to place a period of time; milk liquid can turn cold; also to reheat when breast-feeding, very trouble.In addition feeding bottle can not display bottle in fluid temperature, the adult is when giving Infantile nursing, generally take hand to touch the examination gentleness and try method understanding milk liquid temps such as temperature personally, these method accuracys and wholesomeness are all very poor, because the adult has very big-difference with the infant to the susceptibility and the fitness of temperature, and the intraoral germ of adult and bacterium also can be caused the pollution to drink in the feeding bottle.Prior art also has the feeding bottle of finding to have temperature indicating function or heat insulation function, these feeding bottles or function singleness, and perhaps there is certain defective to some extent in complex structure.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of feeding bottle thermal insulating seat is provided, and it has common feeding bottle is placed on it, and just can show the temperature of milk liquid in the feeding bottle, and the milk liquid in the feeding bottle is had the temperature raising and maintaining function.

The purpose of this utility model is achieved in that a kind of feeding bottle thermal insulating seat, it comprises base, at the top of base clamping rings shape heater, fix a temperature sensor at the base center by spring, there is supply socket side at base, LCD and control button, be built-in with control circuit board in the base bottom, the circuit structure of described control circuit board is, in the heater load loop, be serially connected with bidirectional triode thyristor, the gate pole of this bidirectional triode thyristor is provided the output control terminal of the microprocessor of working power by power conversion and regulator rectifier circuit, work by photoelectricity zero passage driver control heater, the signal input part of microprocessor is connected with the signal input part of operational amplifier, the data input pin of microprocessor is connected with the button inputting circuits that temperature and time is set usefulness, and microprocessor is shown by LCD after analyzing the signal of temperature sensor and button input relatively.

Described annular heater comprises electrothermal tube and heat carrier, and the helical form electrothermal tube is encapsulated in the annular heat carrier.

Between described annular heater and the base certain clearance is arranged, and be fixed on the base by screw.All right filling with insulation material between the gap prevents that base from absorbing heat and heating hot.

The utlity model has following advantage: adopted the feeding bottle thermal insulating seat of independent design, common resistant to elevated temperatures feeding bottle can use this feeding bottle thermal insulating seat temperature display and insulation; The adjusting of temperature and timing is also very simple, only needs just can accurately regulate by the button of base side the holding temperature and the timing of milk liquid, and predetermined holding temperature.Can show by LCD with the current temperature of milk liquid; Adopt the core of microprocessor as control circuit, and with the control circuit design in base, thereby advantage such as whole feeding bottle thermal insulating seat has, and volume is little, in light weight, price is low, and performance is strong.
