Description

Early warning thermos flask

Technical field

The present invention relates to thermos flasks, in particular to a clock early warning thermos flask.

Background technique

Thermos flask is also known as thermos bottle and is also vacuum flask, has applied one layer of silver or reflective coating again in the interlayer of vacuum, heat Radiation gear goes back, then bottleneck is blocked with a plug, and three modes of such heat transfer are all cut-off, and bottle liner can be longer Time keeps temperature, is widely used later, most of to be equipped with thermos flask.And traditional thermos flask is merely able to exercise The general functions such as water receiving, heat preservation, water can overflow during water receiving, not only cause waste, but also be easy to will cause scald etc. Safety problem.

Summary of the invention

1, technical problem to be solved:

Existing thermos flask is made in process of saving water due to not knowing whether, water can overflow, and causes to waste and be easy to cause The safety problems such as scald.

2, technical solution:

In order to solve problem above, the present invention provides a kind of early warning thermos flask, including liner 2, pressure is set in the liner 2 Force snesor 3, the pressure sensor 3 and the integrated circuit 4 being arranged in shell 1 connect, in the integrated circuit board 4 Including encoder and buzzer module, the buzzer is connected with encoder, and the buzzer is arranged on shell 1.

It further include LED light, the LED light is connected with encoder, and described LED etc. is arranged on shell 1.

It further include digital tube display module, the digital tube display module is connected with encoder, and the charactron is aobvious Show that module is arranged on shell 1, the digital tube display module is for showing water level information.

Four input signals of the encoder are followed successively by low level, high level, high level, high level from top to bottom, compile Code three output terminals As 0 of device are low level, A1 is high level, A2 is high level, and the LED light is picked out from A2 mouthfuls；The number Pipe display module picks out from three delivery outlets and first accesses decoder for decoding, is followed by charactron, and buzzer module is picked out from A2 mouthfuls.

Four inputs of the encoder are followed successively by low level, low level, low level, low level, encoder from top to bottom Three output terminals As 0 are high level, A1 is high level, A2 is low level, and the LED light is picked out from A2 mouthfuls；Digital tube display module It is picked out from three delivery outlets and first accesses decoder for decoding, be followed by charactron；The buzzer module and A2 mouthfuls pick out.

3, the utility model has the advantages that

Early warning thermos flask provided by the invention reduces the waste of water when beating hot water, and can be substantially reduced personnel and be scalded The risk of wound.

Specific embodiment

Below by drawings and examples, the present invention is described in detail.

As depicted in figs. 1 and 2, the present invention provides a kind of early warning thermos flask, including liner 2, it is arranged in the liner 2 Temperature sensor 2, the pressure sensor 2 and the integrated circuit 4 being arranged in shell 1 connect, the integrated circuit board 4 In include encoder and buzzer module, the buzzer connect with encoder, and the buzzer setting is on shell 1.

When water level will expire, pressure sensor 3 spreads out of corresponding signal to integrated circuit 4, the encoder of integrated circuit 4 It is encoded accordingly and signal is transported to buzzer module, the alarm of buzzer module prompts the water of thermos flask will be full, makes It is water-saving that the people that fetches water need not wait until that water spilling just stops, and having saved water simultaneously again can be to avoid scald.

It further include LED light to preferably prompt effect, the LED light is connected with encoder, and the LED etc. is set It sets on shell 1.Equally, when water level will expire, pressure sensor 3 spreads out of corresponding signal to integrated circuit 4, integrated circuit 4 encoder is encoded accordingly and signal is transported to buzzer module and LED light, the alarm of buzzer module while LED Lamp dodges contracting, prompts the water of thermos flask will be full, and the people that makes to fetch water need not be until water spilling just stops water-saving, and having saved water simultaneously again can To avoid scald.

It further include digital tube display module to preferably prompt effect, the digital tube display module and encoder Connection, the digital tube display module are arranged on shell 1.The corresponding letter that pressure sensor 3 is experienced SEA LEVEL VARIATION and spread out of Number integrated circuit 4 is arrived, the encoder in integrated circuit 4 is encoded accordingly and output signal is passed to LED module, charactron Display module and buzzer module；Contracting is dodged in the alarm of buzzer module, LED, digital tube display module shows water level percentage.

Embodiment one

As shown in figure 3, the signal that pressure sensor 3 is spread out of makes four input signals of encoder be followed successively by low electricity from top to bottom Flat, high level, high level, high level, three output terminals As 0 of encoder are low level, A1 is high level, A2 is high level, at this moment LED module is picked out from A2 mouthfuls becomes low level by NOT gate, and LED does not work；Digital tube display module picks out elder generation from three delivery outlets Decoder for decoding is accessed, charactron, numeral method 1 are followed by；Buzzer module is picked out from A2 mouthfuls, is high level, buzzer is not It rings.

Embodiment two

As shown in figure 4, the signal that sensor 3 is spread out of make four of encoder input be followed successively by from top to bottom low level, low level, Low level, low level, three output terminals As 0 of encoder are high level, A1 is high level, A2 is low level, at this moment LED module from A2 mouthfuls pick out and become high level by NOT gate, and LED is bright；Digital tube display module picks out first access decoder from three delivery outlets and translates Code, is followed by charactron, numeral method 4；Buzzer module is picked out from A2 mouthfuls, is low level, and buzzer is rung.

Although the present invention has been described by way of example and in terms of the preferred embodiments, they be not it is for the purpose of limiting the invention, it is any ripe This those skilled in the art is practised, without departing from the spirit and scope of the invention, can make various changes or retouch from working as, therefore guarantor of the invention Shield range should be subject to what claims hereof protection scope was defined.
