Wherein, the vessel 1 is for example but not limited to a funnel shape, having an outlet 11 and a space 12 extended outwardly from one side of the vessel 1; furthermore, the vessel 1 of the present invention further comprises a handle 13 and the space 12 further has a plurality of ring-shaped trenches 121.
The tube 2 is for example but not limited to a soft pipe, wherein one side of the tube 2 is coupled to the outlet 11 for transporting water from the vessel 1 to the float device 3.
The float device 3 has a housing 31 and a float 32, wherein the float 32 is disposed inside the housing 31 and the housing 31 has at least one opening 33 and one side of the housing 31 is connected to the other side of the tube 2. The float 32 of the present invention is for example but not limited to a magnet and its position in the housing 31 can be varied according to the water level of the housing 31. Furthermore, both sides of the housing 31 of the float device 3 are open, and it further comprises a lower cover 34 for plugging into the lower side of the housing 31 so as to prevent the water leaking form the housing 31.
The control device 4 has a housing 41 and a control circuit 42, wherein the housing 41 is positioned beside the housing 31 of the float device 3 and the control circuit 42 is disposed inside the housing 41
The warning device 5 is disposed inside the space 12 and coupled to the control circuit 42. Furthermore, the warning device 5 further comprises a speaker 51 and an indicator 52, wherein the speaker 51 and indicator 52 is disposed inside the space 12, respectively, and the indicator 52 is for example but not limited to a LED and protruded from the ring-shaped trenches 121 so as easy to observe. The vessel 1, tube 2, housing 31 and housing 41 are made of insulating materials, for example but not limited to plastic.

While the water level of the housing 31 approaching to the lower water level, due to the float 32 is floated above the water, therefore the float 32 will approach to the first magnetism switch 423 and the first magnetism switch 423 will be conducted by way of the magnetic force of the float 32 and causes the microcontroller 422 generating a first control signal to the warning device 5; while the float 32 approaching to the higher water level, due to the float 32 is floated above the water, therefore the float 32 will approach to the second magnetism switch 424 and the second magnetism switch 424 will be conducted by way of the magnetic force of the float 32 and causes the microcontroller 422 generating a second control signal to the warning device 5.
Wherein, the first control signal represents the float 32 approaching to a lower water level, and the microcontroller 422 will generate a short-interval, for example but not limited to 30 seconds interval warning signal through the speaker 51, or generate red light warning signal through the LED 52 for reminding the user to fill water. Wherein, the second control signal represents the float 32 approaching to a higher water level, and the microcontroller 422 will generate long-interval, for example but not limited to 60 seconds warning signal through the speaker 51 for reminding the user that the water level is approaching to the higher water level. While the water level of the housing 31 is between the lower water level and the higher water level, namely, the water level of the housing 31 is in a normal state, the microcontroller 422 will drive the LED 52 to emit green light.
According to the smart filling device of the present invention, the user can obtain the position of the float 32 by observing the color of the LED 52 or listening to the sound generated by the speaker 51 to determine whether fills water or not, such that the aforesaid drawbacks of the prior art water filling system can be overcame.
While the invention has been described with reference to preferred embodiment thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
