Abstract

The utility model relates to a food spoon with a temperature induction function. The food spoon comprises a food spoon body composed of a spoon head and a spoon handle. The food spoon is characterized in that a temperature induction probe is arranged in the spoon head, a temperature and electric signal conversion device is arranged in the spoon handle, and the temperature and electric signal conversion device is connected with a liquid crystal display screen arranged on the surface of the spoon handle. The food spoon has the advantages of having the temperature induction function and integrating stirring with temperature measurement. When water or liquid food is poured in a cup, the temperature can be displayed after induction of the spoon, whether a most reasonable drinking effect is achieved can be judged, and whether health care products can be absorbed by a human body in the greatest degree can be judged. Meanwhile, the food spoon can remind old people and children to drink the water or the liquid food at a proper temperature, and is integrated with functionalization and humanization.

Description

The temperature sense food spoon

Technical field

The utility model belongs to daily necessities, relates in particular to a kind of temperature sense food spoon.

Background technology

Soup ladle is that people are used for the aqueous liquid foodstuff in bowl or cup is scooped out to edible daily living article.But eat soup or during other food liquids, people can't expect the temperature of soup or food liquid, frequent careless hand or the mouth of scalding, can especially the elderly and children, too high or too low for temperature, can't remind them drink, therefore the personal injury that can meet accident.People's health care consciousness improves constantly thereupon, and a lot of health products, in order to realize the optimum efficiency of absorption of human body, have requirement more accurately to the temperature of taking.For example, collagen is that people's in-vivo content is maximum, and the widest protein that distributes makes the main matrix of skin, blood vessel, bone, muscle tendon and cartilage.Collagen protein powder is rich in the micromolecular collagen peptide that benefits absorption of human body, and wherein the content of hydroxyproline is up to 11.8%-12.6%.Instant Drinks in the warm water that is≤50 ℃ in temperature or milk or fruit juice, human body absorbs best to micromolecular collagen peptide.But people use at present cup or soup ladle all can't provide temperature accurately.Therefore work as people water is poured in cup, also just can't judge whether to reach optimal Instant Drinks effect, whether can meet the maximum absorption effect.A kind of spoon that can show drinking-water or liquid food temperature is urgently released in market.

The utility model content

The utility model is in order to overcome deficiency of the prior art, and a kind of temperature sense food spoon that can show drinking-water or liquid food temperature is provided.

The utility model for achieving the above object, be achieved through the following technical solutions, a kind of temperature sense food spoon, comprise the food spoon body that spoon head and kettleholder form, it is characterized in that: be provided with the temperature sense probe in described spoon head, be provided with temperature and electrical signal conversion device in described kettleholder, described temperature is connected with the LCDs that is placed in the kettleholder surface with electrical signal conversion device.

The described temperature sense probing shell metal material good by heat conduction made, the built-in thermistor of temperature sense probing shell.

Described temperature and electrical signal conversion device comprise that integration module, thermistor and resistor form measuring bridge, and described integration module is connected with the clasp battery with LCDs respectively, and described integration module comprises A/D translation circuit and function prompt circuit.

Described integration module is connected with Microspeaker.

Described integration module is connected with the power switch that is located at the kettleholder surface.

Described power switch adopts the soft-touch type Minisize press button switch.

Described kettleholder surface is provided with the groove of accommodating temperature and electrical signal conversion device and LCDs.

Beneficial effect: there is the temperature sense function, integrate the product stirred with thermometric.When water or food liquid are poured in cup, realize after can feeling by spoon that temperature shows, judge whether to reach the Instant Drinks effect of rationalizing most, whether health products can reach the maximized assimilation effect of human body.Also can remind the elderly and children, drinking water or food liquid under applicable temperature conditions, integrate functionalization and hommization simultaneously.

The accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is circuit catenation principle figure of the present utility model.

The specific embodiment

Below in conjunction with preferred embodiment, details are as follows for the specific embodiment that foundation the utility model is provided: refer to accompanying drawing, a kind of temperature sense food spoon, comprise the food spoon body that spoon head 1 and kettleholder 2 form, be provided with temperature sense probe 3 in described spoon head, be provided with temperature and electrical signal conversion device in described kettleholder, described temperature is connected with the LCDs 4 that is placed in the kettleholder surface with electrical signal conversion device.

Refer to accompanying drawing 2, described temperature and electrical signal conversion device comprise that integration module, thermistor and resistor form measuring bridge, described integration module is connected with the clasp battery with LCDs respectively, and described integration module comprises A/D, translation circuit and function prompt circuit.Integration module is the ICL7107 converter, and ICL7107 is high-performance, the three-dimensional half A/D change-over circuit of low-power consumption.It includes segment decoder, display driver, reference source and clock system.Can directly drive Light-Emitting Diode LED.ICL7107 is by high accuracy, and versatility well combines, and the automatic effect zero power energy lower than 10uV is arranged, and drift is less than the 1uV/ degree.

Main feature:

While guaranteeing the zero level input, the value of each two range is zero

Very low noise

Differential input and differential reference source, directly LED display driver

Do not need to be circumscribed with source circuit

Low-power consumption

Main Function:

Import the temperature of inductive probe into ICL71071, by its inner A/D conversion, directly temperature is presented on LCD.

Described integration module is connected with Microspeaker.Described integration module is connected with the power switch 5 that is located at the kettleholder surface.Described power switch adopts the soft-touch type Minisize press button switch.Described kettleholder surface is provided with the groove of accommodating temperature and electrical signal conversion device and LCDs.

The shell metal material good by heat conduction of temperature sense probe made, the built-in thermistor of accurately revising through laser.

It is that core, thermistor RT, precision-matched resistor R, LCD, superminiature piezoelectric loudspeaker, button cell E, power knob K switch form that the extensive IC of flexible package be take with temperature and electrical signal conversion device in kettleholder inside.The IC internal main will be by the measuring bridge formed with RT, R, A/D conversion, function prompt the electric circuit constitute.Precision-matched resistor R is in temperature-sensitive head being put to what benchmark insulating box the time and RT strictly matches, and adopts the little precision resistor of temperature coefficient.

Nontoxic glue and kettleholder groove surrounding gummed for the shell of LCDs, firm reliable.
