Abstract

The utility model relates to a gravity control type electric kettle. The gravity control type electric kettle comprises an electric kettle body and an electric kettle base; the electric kettle base comprises a touch main power switch, a gravity sensor, a display screen, a single-chip microcomputer, a control circuit and a relay; when the electric kettle body is put on the electric kettle base, the touch main power switch is on, when a memory button is pushed, the single-chip microcomputer gives orders, the control circuit enables the relay to be closed, and then a heating device at the bottom of the electric kettle body starts heating; the gravity sensor is capable of displaying the water storage volume through the display screen and transmitting display data to the single-chip microcomputer, and the single-chip microcomputer is connected with the control circuit which is connected with the relay. The gravity control type electric kettle has the advantages that the electric kettle body needs no pneumatic switch and plastic connector, so that more environment friendliness and safety are achieved; water can be continuously heated for a while after being boiled, and consequently sanitary requirements can be better met; according to the fact that the total gravity is reduced during vaporization, and the heating device is automatically cut off under the control of the single-chip microcomputer, so that novelty and practicality are achieved.

Description

A kind of GRAVITY CONTROL electric kettle

Technical field

The present invention relates to electric kettle, relate in particular to a kind of GRAVITY CONTROL electric kettle.

Background technology

The present invention is to notification number CN201806543U, supplementing of a kind of prior art of base of electric heating kettle, this utility model discloses, on the base of placing at kettle, connect electronic scale power supply, display just can show the weight of water outlet, by Conversion of measurement unit button, can convert the weight of water to water level or volume shows in display, user can understand the number of the water yield in kettle intuitively, without on kettle body, water gauge being set, kettle body there will not be and leaks, when being greater than maximum amount of water or being less than least quantity, the water yield that can also measure by electronic scale sends alarm, but the practicality of this technical functionality is comprehensive not enough, if utilize GRAVITY CONTROL electric heating kettle heating switch, just have more practicality, reach its due technological value.

Electric kettle in the market in addition, most jettrons that adopt, the advantage of this device is the switch of cutting off the electricity supply rapidly, shortcoming is that the water in electric kettle can not continue to heat about 3 minutes after boiled again, some harmful germs can not be killed, and the electric kettle with jettron is that Bian makes with plastic products, and most plastics are all poisonous plastics, this just causes the electric kettle product quality on market very different; Use is with the kettle of poisonous plastics, and directly harmful to human is healthy, therefore safer without the insulating pot of plastic products, and the kettle body of the electric kettle of GRAVITY CONTROL, comprises that pot lid can accomplish all steel, and boiled water can directly not contact parts of plastics.

Summary of the invention

The object of this invention is to provide a kind of electric kettle that utilizes GRAVITY CONTROL, the kettle of weighing, after hot water is boiled, along with the minimizing of water-holding quantity in kettle, control circuit can cut out heater switch automatically.

For achieving the above object, the technical solution used in the present invention is: a kind of GRAVITY CONTROL electric kettle, comprises insulating pot, base of electric kettle, touching total power switch, gravity sensor, display screen, memory heat button, single-chip microcomputer, control circuit, relay, voice module; It is characterized in that: heater is contained in described kettle bottom, by circular spliced eye, be connected with kettle base control circuit, described kettle base comprises touching total power switch, gravity sensor, display screen, single-chip microcomputer, control circuit, relay, described touching total power switch is opened when insulating pot is put on base of electric kettle, when pressing again memory heat button, single-chip microcomputer sends instruction, and control circuit makes relay closes, and insulating pot bottom heating device starts heating; Described gravity sensor can show water-holding quantity by display screen, and can be by display data transmissions to single-chip microcomputer, and described single-chip microcomputer is connected with control circuit, and described control circuit is connected with relay.

Single-chip microcomputer is provided with the water-holding quantity upper limit and lower limit, exceeds the upper limit or lower than lower limit, voice module can be pointed out; Also designed the longest working time of the each heating of control circuit, when pressing memory heat button, the single-chip microcomputer gravity value that record gathers automatically, after water is boiled, when collection value reduces 20 grams, single-chip microcomputer can send instruction, the automatic block system relay of control circuit, heater stop work.

The invention has the beneficial effects as follows: kettle body is without jettron and plastic fastening more environmental protection, safety; After boiling water is boiled, can also continue to burn a period of time, more meet hygienic requirements, while utilizing water vapor, total force reduces, and by Automatic control of single chip microcomputer, cuts off heater, has more novelty and practicality.
