Abstract

The invention discloses a milk warmer which comprises a box body, two enclosed hollow hot plates, a temperature sensor, a relay, a power supply and a single-chip microcomputer, wherein the temperature sensor is fixed in the box body, a resistance wire is arranged in the cavity of each enclosed hollow hot plate, the cavity is filled with water, the resistance wires, the power supply and the relay are serially connected to form a loop, and a thermal insulation layer is arranged on one side of each enclosed hollow hot plate. The thermal insulation layers are connected with the inner wall of the box body through springs, and a display, the button module, the temperature sensor and the relay are respectively connected with the a single-chip microcomputer. The milk warmer is simple in structure, realizes real time temperature control of the milk warmer through the relay and the single-chip microcomputer. The distance between two enclosed hollow hot plates is adjusted through springs. The milk warmer is excellent in universality and wide in use scope.

Description

A kind of milk lukewarm

Technical field

The present invention relates to a kind of milk lukewarm, particularly relate to a kind of variable volume and can the milk lukewarm of temperature control in real time.

Background technology

, often there is following shortcoming, one in milk lukewarm commercially available at present: milk lukewarm cannot temperature control, be easy to cause Repeat-heating, the nutrition of the drinks such as milk is destroyed, two: the immobilization of milk lukewarm inner space, can not be applicable to the milk beverage of Different Package, universality is poor, and efficiency is not high.

Summary of the invention

The object of the invention is to the problem for prior art, provide a kind of can temperature control and the milk lukewarm of variable volume in real time.

Milk lukewarm of the present invention, comprise box body, vertically in box body be provided with two pieces of parallel airtight hollow heating plates, the one side of airtight hollow heating plate has heat insulation layer, there is between heat insulation layer and inboard wall of cartridge some springs, one end and the inboard wall of cartridge of spring offset, the other end and heat insulation layer offset, in the cavity of airtight hollow heating plate, there is resistance wire and be filled with water, the power supply that resistance wire and box body are arranged and relay loop in series, temperature sensor is provided with inside Bottom of box body, temperature sensor is between two airtight hollow heating plates, box body is provided with display and key-press module, single-chip microcomputer is fixed with bottom box body, display and key-press module, temperature sensor, relay is connected with single-chip microcomputer respectively with power supply.

In technique scheme, described single-chip microcomputer can adopt K60 type single-chip microcomputer.

Described heat insulation layer is generally asbestos, rock wool, glass fibre or aerogel blanket.

Structure of the present invention is simple, and by the real-time temperature control of relay and chip microcontroller milk lukewarm, and the distance between two blocks of airtight hollow heating plate plates regulates by spring, and universality is strong, and the scope of application is wide.

Accompanying drawing explanation

Fig. 1 is the structural representation of milk lukewarm of the present invention;

Fig. 2 is the control principle schematic diagram of milk lukewarm of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention will be further described.

See figures.1.and.2, milk lukewarm of the present invention, comprise box body 1, vertically in box body 1 be provided with two pieces of parallel airtight hollow heating plates 3, the one side of airtight hollow heating plate 3 has heat insulation layer 5, between heat insulation layer 5 and box body 1 inwall, there is some springs, one end and the inboard wall of cartridge of spring offset, the other end and heat insulation layer 5 offset, in the cavity of airtight hollow heating plate 3, there is resistance wire 4 and be filled with water, the power supply 6 that resistance wire 4 and box body are arranged and relay 7 loop in series, temperature sensor 2 is provided with inside Bottom of box body, temperature sensor 2 is between two airtight hollow heating plates 3, box body 1 is provided with display and key-press module 8, single-chip microcomputer 9 is fixed with bottom box body 1, display and key-press module 8, temperature sensor 2, relay 7 is connected with single-chip microcomputer 9 respectively with power supply 6.

In technique scheme, described heat insulation layer 5 can be asbestos, rock wool, glass fibre or aerogel blanket.

Described single-chip microcomputer can adopt the chip of K60 model, and display and key-press module can adopt OLED LCDs and arrange " 0-9 ", " confirmation ", " cancellation " 12 buttons.

Milk lukewarm of the present invention adopts the structure of simple parallel heating plates can realize milk lukewarm internal adjustable volume in conjunction with spring, and real-time temperature control when realizing the hot milk of milk lukewarm by single-chip microcomputer, relay and temperature sensor.Detailed process is as follows:

During milk lukewarm inoperative, spring is in lax state, when milk products packaging is put into box and is clamp-oned two pieces of hollow heating plates 3, the spring-compressed of both sides makes two pieces of hollow heating plates 3 be clamped by milk pack, switch on power after 6, user inputs the temperature preset by display and key-press module 8, the temperature sensor 2 being positioned at milk lukewarm box body 1 inside constantly detects the temperature of milk pack, and by this information transmission to single-chip microcomputer 9, the preset temperature that itself and user input compares by single-chip microcomputer 9, when actual temperature is lower than preset temperature, Single-chip Controlling relay 7 is connected, resistance wire 4 in two pieces of airtight hollow heating plates 3 is heated, heat is undertaken transferring to heating plate front by the water in airtight hollow heating plate, thus heating milk.When the actual temperature that temperature sensor detects reaches preset temperature, Single-chip Controlling relay disconnects and stops heating.
