The invention discloses a heat preservation nursing bottle which belongs to nursling articles for daily use, the heat preservation nursing bottle comprises a nipple, a bottle cap and a bottle body; an attemperator is arranged at the lower part of the bottle body and includes a base, and a ring-shaped heater which is tightly contacted with the bottle body is fixed at the upper part of the base; the center of the base is fixed with a temperature sensor which props against the bottom of the bottle body by a spring; the side of the base is provided with a mains jack, a liquid crystal display device and a control keystoke, and a control circuit board that adopts a microprocessor as the core is arranged inside the lower part of the base. The heat preservation nursing bottle can accurately regulate the temperature of the milk and the timing time by the keystoke, and the reserved holding temperature, the current temperature of the milk and the time can be displayed on the liquid crystal display device; at the same time, the heat preservation nursing bottle has the advantages of small volume, light weight, low price and strong performance, etc.

Description

A kind of thermal insulation nursing bottle

Technical field

The present invention relates to the infant articles for daily use, especially a kind of thermal insulation nursing bottle.

Background technology

Common feeding bottle does not generally all have temperature to show or temperature control equipment, and milk is transferred and converted after regular meeting runs into the situation that the baby does not temporarily eat, because feeding bottle does not have heat insulation function, after placement a period of time, milk can turn cold, and also will reheat very trouble when breast-feeding.Feeding bottle can not show the milk liquid temp, and the adult generally takes hands to touch the examination gentleness when giving Infantile nursing and tries 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 infant to the sensitivity and the fitness of temperature, and the intraoral pathogenic bacteria of adult and antibacterial also can be caused the pollution to beverage in the feeding bottle.

Although the existing open even conversion production of feeding bottle that much has the feeding bottle or the heat insulation function of temp sensing function, technology as temp sensing function has bottle wall that thermometer is installed, temperature sensing paint is attached to a bottle wall outside and carries out thermometric, the technology of heat insulation function has the Dewar bottle wall, has feeding bottle of hot water jacket or the like, yet all there is certain defective in these technology.

Summary of the invention

The objective of the invention is to overcome the defective of above-mentioned existing feeding bottle technology, a kind of thermal insulation nursing bottle is provided, it not only can show the temperature of beverage in the feeding bottle, but also has the temperature raising and maintaining function.

The object of the present invention is achieved like this: a kind of thermal insulation nursing bottle, it comprises nipple, bottle cap and body, it is characterized in that: it also comprises the attemperator that is enclosed within the body bottom, this device comprises base, at the fixing annular heater that closely contacts with body in the top of base, fix a temperature sensor that withstands on the body bottom at the base center by spring, there is supply socket side at base, liquid crystal display 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 to pass through the work of photoelectricity zero passage driver control heater by power conversion and regulator rectifier circuit, 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 liquid crystal display after analyzing the signal of temperature sensor and button input relatively.

Described annular heater closely contacts its purpose with body and is to make the heat of heater to pass to bottle efficiently, thereby gives the milk temperature raising and maintaining.This part structure can be designed to helicitic texture, and the annular heater has female thread, and external screw thread is arranged at the body bottom, and both are by the screw thread combination.

Described body outer wall has the convex stripe of frosted structure.

The striped of described frosted structure is at body outer wall shape in the shape of a spiral.This design bottle is elegant in appearance, and the spiral salient of frosted place simultaneously can reduce heating surface area and the heating degree when holding feeding bottle, and user also can be taken feeding bottle under the higher a little condition of temperature.

Described portable handle is the adnexa that can freely assemble, and places the bottle cap below, and it is fixed between bottle cap and the body when bottle cap is tightened.Its effect mainly is to make things convenient for the head of a family and child to hold feeding bottle, and can utilize this handle that feeding bottle is carried out displacement when the feeding bottle temperature is too high.

Compared with prior art, the present invention has following advantage:

Because the thermal insulation nursing bottle that the present invention proposes adopts the core of microprocessor as control circuit, and with the control circuit design in base, thereby advantage such as whole thermal insulation nursing bottle has, and volume is little, in light weight, price is low, and performance is strong; The adjusting of simultaneous temperature and timing is very simple, only needs just can accurately regulate by the lateral button of base the temperature and the timing of milk, and predetermined holding temperature and milk temperature and time now can show by liquid crystal display; At the convex stripe that the body outer wall has the frosted structure, can reduce heating surface area and heating degree when holding feeding bottle, make user under the higher a little condition of temperature, also can take feeding bottle.Designed the portable handle adnexa that can freely assemble, it can make things convenient for the head of a family and child to hold feeding bottle, and can utilize this handle that feeding bottle is carried out displacement when the feeding bottle temperature is too high.
