Abstract

Disclosed is water heating kettle with electronic reminding function. The mechanical parts of the water heating kettle include a transformer, an NC555 control chip, an electronic input counter, an electric heating coil, a temperature sensor, a loudspeaker and a water storage barrel. The water heating kettle is characterized in that the A circuit of the NC555 control chip is connected with a thermistor, the B circuit of the NC555 control chip is connected with the electric heating coil, the C circuit of the NC555 control chip is connected with the electronic input counter, and the D circuit of the NC555 control chip is connected with the loudspeaker. The water heating kettle with electronic reminding function has the functions of heating the water circularly, automatically controlling the water temperature and giving an alarm when the water temperature reaches the set value.

Description

Electronic reminding adds hot-water bottle

Technical field

The utility model relates to a kind of instrument that brews of finished tea, is that a kind of electronic reminding adds hot-water bottle concretely.

Background technology

At present, finished tea generally adopts boiling water to be used as the overwhelming majority that accounted for that tealeaves brews, this mechanism simple structure, but have obvious weak point: because long boiling water of time is lowered the temperature, the tea quality does not reach the own quality requirements of tealeaves etc.

The utility model content

The purpose of this utility model is to provide a kind of electronic reminding to add hot-water bottle, makes guaranteeing former brewing on the simple basis of tool configuration, also has the cooling of the water temperature of elimination, and the electronic reminding that can be used as the instrument that brews of finished tea adds hot-water bottle.

The utility model is realized with following technical scheme: this electronic reminding adds hot-water bottle and mainly is made up of transformer, NC555 control chip, electronics enter counter, electrically-heated coil, temperature sensor, loudspeaker, impounding kettle.It is characterized in that: the A circuit of NC555 control chip is connected with thermistor, and the B circuit of NC555 control chip is connected with electrically-heated coil, and the C circuit of NC555 control chip is connected with the electronics enter counter, and the D circuit of NC555 control chip is connected with loudspeaker.At first impounding kettle being placed on electronic reminding adds above the hot-water bottle, the power supply that electronic reminding adds hot-water bottle is connected with the civil power of 220V, after becoming the 12V electric energy, the transformer transformation adds hot-water bottle supply electric energy to electronic reminding by red line and green line, the NC555 control chip is when receiving the setup parameter of electronics enter counter C circuit, the NC555 control chip provides electric energy electrically-heated coil heating work by the B circuit to electrically-heated coil, the water temperature of impounding kettle feeds back to the NC555 control chip through temperature sensor A circuit, when water temperature conforms to the data of electronics enter counter input, the NC555 control chip stops the electric energy of B circuit, electrically-heated coil quits work, simultaneously, NC555 control chip conducting D circuit loudspeaker piped 5 seconds; When water temperature is lower than 3 ° of the setting values of electronics enter counter, the conducting B line electricity heat coil work once more of NC555 control chip, so circulation has realized the automatic control and the prompting function of water temperature.

Compared with the prior art, using this electronic reminding to add hot-water bottle, can to solve the error of water temperature big, influences the tea quality, do not have drawbacks such as prompting.

In sum,, this electronic reminding has that to solve the water temperature error big just because of adding hot-water bottle, thus the tea quality when promoting tealeaves and brewing.

Description of drawings

Accompanying drawing is the fundamental diagram that the utility model electronic reminding adds hot-water bottle.

1. transformers among the figure, 2.NC555 control chip, 3. electronics enter counter, 4. electrically-heated coil, 5. thermistor, 6. loudspeaker, 7. impounding kettle.

Embodiment

Fig. 1 is the fundamental diagram that the utility model electronic reminding adds hot-water bottle, and its principle of work is made up of transformer (1), NC555 control chip (2), electronics enter counter (3), electrically-heated coil (4), thermistor (5), loudspeaker (6), impounding kettle (7).In the accompanying drawings, the A circuit of NC555 control chip (2) is connected with thermistor (5), the B circuit of NC555 control chip (2) is connected with electrically-heated coil (4), the C circuit of NC555 control chip (2) is connected with electronics enter counter (3), and the D circuit of NC555 control chip (2) is connected with loudspeaker (6).At first impounding kettle (7) being placed on electronic reminding adds above the hot-water bottle, the power supply that electronic reminding adds hot-water bottle is connected with the civil power of 220V, after becoming the 12V electric energy, transformer (1) transformation adds hot-water bottle supply electric energy to electronic reminding by red line and green line, NC555 control chip (2) is when receiving the setup parameter of electronics enter counter (3) C circuit, NC555 control chip (2) provides electric energy electrically-heated coil (4) heating work by the B circuit to electrically-heated coil (4), the water temperature of impounding kettle (7) feeds back to NC555 control chip (2) through temperature sensor A circuit, when water temperature conforms to the data of electronics enter counter (3) input, NC555 control chip (2) stops the electric energy of B circuit, electrically-heated coil (4) quits work, simultaneously, NC555 control chip (2) conducting D circuit loudspeaker (6) piped 5 seconds; When water temperature is lower than 3 ° of the setting values of electronics enter counter (3), NC555 control chip (2) conducting B line electricity heat coil (4) work once more, so circulation has realized the automatic control and the prompting function of water temperature.

Claims
