To avoid the influence to AD conversion chip 122, the service life of extension AD conversion chip 122.
Easy full of beard and, after AD conversion chip 122 can merge into a module namely be merged with control module 123
Module not only included the function of AD conversion chip 122, but also include the function of control module 123, it is impossible to pass through AD conversion chip 122
Merging or separating type with control module 123 limit the protection domain of the application.
In a kind of possible realization method, control module 123 can be an independent module, can realize to AD
The voltage signal that conversion chip 122 exports carries out digital conversion, and can realize and determine to correspond to according to transformed digital signal
Control instruction, can also realize and control instruction is sent into feed pump 130 so that water pump 130 to be controlled to perform corresponding operating.
Certainly, control module 123 can also be split as the combination of multiple functional units, in a kind of optional mode, control
Module 123 can include analytic unit 123a and control unit 123b, input terminal and the AD conversion chip 122 of analytic unit 123a
Output terminal be electrically connected, the output terminal of analytic unit 123a and the input terminal of control unit 123b are electrically connected, control unit
The output terminal of 123b adds taps to be electrically connected with water pump 130.Analytic unit 123a can determine that AD conversion chip 122 exports
Digital signal corresponding to control instruction, control instruction is sent to control unit 123b, control unit 123b is according to control
Instruction control plus taps are closed or disconnect.
Generally, the correspondence between digital signal and control instruction, root can be prestored in analytic unit 123a
According to the digital signal that AD conversion chip 122 exports, corresponding control instruction is determined.In general, digital signal and control instruction
Between correspondence can according to the capacity of water container, need plus the water level of water or water etc. experiment determines in advance.It is general next
It says, the water container of different capabilities or the electric kettle of different model, the weight of water container may be different, although having identical
The water of weight, but measure it is important may be different, the corresponding pass between corresponding digital signal and control instruction
System is also different, therefore in actual implementation, can add water water level previously according to the specification of water container and the suitable of setting
To test the correspondence determined between the corresponding digital signal of the water container and control instruction.
Obviously, analytic unit 123a can also obtain the corresponding pass between storage digital signal and control instruction from server
System, alternatively, analytic unit 123a can obtain control instruction corresponding with digital signal from server, it can be advance in server
Store the correspondence between the digital signal and control instruction of the electric kettle of various models.
Optionally, analytic unit 123a is obtaining the correspondence between storage digital signal and control instruction from server
When, the correspondence identified with electric heater or water container can be sent to server and obtains request, server is then to analysis
Unit 123a feeds back the correspondence between the electric heater or the relevant digital signal of water container mark and control instruction.
Optionally, analytic unit 123a, can be to clothes when obtaining control instruction corresponding with digital signal from server
Business device sends to obtain with electric heater or the control instruction of water container mark and digital signal and ask, and server is then to analysis
Unit 123a is fed back identifies relevant control instruction corresponding with the digital signal with the electric heater or water container.
In this application, the control instruction that analytic unit 123a is determined can at least include plus water instructs and/or stops adding
Water instruct, control unit 123b receive plus water instruction after, control water pump 130 perform plus water operation, such as control water pump 130
Plus taps be closed, so as to which water pump 130 be controlled to add water to water container；Control unit 123b is receiving stopping plus water instruction
Afterwards, control water pump 130 perform stop plus water operation, such as control water pump 130 plus taps disconnect, so as to cause water pump 130
Stop adding water to water container.
Since weighing sensor 121 is in weighed vary in weight, different voltage or different weighing can be exported
During object in weight range, voltage corresponding with weight range can be exported, therefore the voltage that exports of weighing sensor 121 can be with
For reflecting 121 weighed weight of weighing sensor.
For example, when the voltage that weighing sensor 121 exports is located at first voltage range, AD conversion chip 122 exports
The first digital signal corresponding with the voltage, analytic unit 123a is according to the corresponding pass between the digital signal to prestore and instruction
System determines instruction corresponding with the first digital signal to add water instruction；The voltage that weighing sensor 121 exports is located at the second electricity
When pressing scope, AD conversion chip 122 exports the second digital signal corresponding with the voltage, and analytic unit 123a is according to the number to prestore
Correspondence between word signal and instruction determines instruction corresponding with the second digital signal to stop adding water instruction.
In general, in first voltage range voltage reflection water container in water it is less, it is necessary to plus water, second voltage scope
Interior voltage is for reflecting that water is more in water container, for example warp-wise water container has added the water of a period of time to water pump 130, at this time then
It needs to stop adding water.
Since weighing sensor 121 can sense the weight of weighed amount object in real time, and the electricity of output is arrived in reflection in real time
In pressure, therefore, weighing sensor 121 can export voltage corresponding with 110 weight of water container in real time.It is corresponding, control mould
Block 123 can also determine control instruction corresponding with 110 weight of water container in real time.
In conclusion Intelligent electric kettle provided by the embodiments of the present application, by weighing sensor to the water of electric kettle
The weight of container measures, and exports corresponding with measured weight voltage signal, and is finally determined according to voltage signal pair
The control instruction answered, water pump to be controlled to add water to water container or stops adding water, can make water pump adds water opportunity or stopping plus water
Opportunity is determined by water in water container, and then ensures that the perseverance of water in water container is steady, avoids the dilutional hyponatremia or very few in water container,
And then can be not thorough to avoid the dry combustion method to water container or heat up water, it ensure that the safe to use of electric kettle.
