Description
Technical field
The utility model relates to household appliance technical field, is specifically a kind of electric kettle with overweight warning device.
Background technology
Electric kettle is a kind of household electrical appliance, uses very general in daily life.But in prior art, the mark of electric kettle maximum amount of water is generally placed on inner side, is not clearly, does not slightly note during water receiving, the situation of water receiving excess will occur.After water is boiled, the water of boiling will overflow, and will spray the skin of hurting sb.'s feelings because of carelessness, severe patient also can cause short circuit.
Utility model content
Problem to be solved in the utility model is to provide the electric kettle that a kind of structure simply has overweight warning device, and it can prevent the water spilling of seething with excitement from hurting sb.'s feelings, avoiding short circuit.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of electric kettle with overweight warning device, the electrical bar comprising kettle body and be arranged in kettle body, it is characterized in that: it also comprises overweight warning device, described overweight warning device comprises pressure sensor, control module, relay and sound-producing device, described pressure sensor is arranged on the bottom of kettle body, described relay, pressure sensor, sound-producing device are connected with described control module respectively, and described relay is connected with described electrical bar.
Preferably, the above-mentioned electric kettle with overweight warning device, the single-chip microcomputer that wherein said control module comprises A/D module and is connected with described A/D module, described pressure sensor is connected with described A/D module, and described single-chip microcomputer is connected with described sound-producing device, relay respectively.
Preferably, the above-mentioned electric kettle with overweight warning device, the base of wherein said kettle body is provided with groove, is provided with pcb board in described groove, described single-chip microcomputer, A/D module are arranged on described pcb board.
Preferably, the above-mentioned electric kettle with overweight warning device, wherein said groove is connected with lid.
Preferably, the above-mentioned electric kettle with overweight warning device, wherein said single-chip microcomputer adopts STC89C52RC chip.
Preferably, the above-mentioned electric kettle with overweight warning device, wherein said A/D module adopts HX711AD chip.
Preferably, the above-mentioned electric kettle with overweight warning device, wherein said sound-producing device is arranged on the base of kettle body, and this sound-producing device adopts toy trumpet.
Technique effect of the present utility model is mainly reflected in: pressure sensor can detect hydraulic pressure bottom kettle body and by signal transmission to A/D module, A/D module converts the signal into digital signal transfers to single-chip microcomputer, when the hydraulic pressure detected is greater than the settings of single-chip microcomputer, monolithic processor controlled sounding device sends voice prompt, and disconnect relay stop electrical bar being powered, reminding user dress water overfill, rear spilling is hurted sb.'s feelings, short circuit to avoid water to seethe with excitement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the theory diagram of the overweight warning device in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is told about further, be easier to make the technical solution of the utility model understand and grasp.
As shown in Figure 1, a kind of electric kettle with overweight warning device, comprise kettle body 1 and be arranged on the electrical bar 2 in kettle body, it also comprises overweight warning device, overweight warning device 3 comprises pressure sensor 31, control module 32, relay 33 and sound-producing device 34, pressure sensor 31 is arranged on the bottom of kettle body 1, the single-chip microcomputer 322 that control module 32 comprises A/D module 321 and is connected with A/D module 321, pressure sensor 31 is connected by wire with A/D module 321, single-chip microcomputer 322 respectively with sound-producing device 34, relay 33 is connected by wire, relay 33 is connected with electrical bar 2, single-chip microcomputer 322 adopts 5V Power supply, the alternating current of 220 is received above the normal opened contact of relay 33.
The base of kettle body 1 is provided with groove 11, is provided with pcb board 35 in groove 11, single-chip microcomputer 322, A/D module 321 are arranged on pcb board 35, and groove 11 place is connected with lid 12.Single-chip microcomputer 322 adopts STC89C52RC chip, and A/D module 321 adopts HX711AD chip.Its repeat circuit 33 is also arranged in groove 11.Sound-producing device 34 is arranged on the base of kettle body 1, and it adopts toy trumpet.
As shown in Figure 2, pressure sensor 31 can detect hydraulic pressure bottom kettle body 1 and by signal transmission to A/D module 321, A/D module 321 converts the signal into digital signal transfers to single-chip microcomputer 322, when the hydraulic pressure detected is greater than the settings of single-chip microcomputer 322, single-chip microcomputer 322 controls sound-producing device 34 and sends voice prompt, and disconnect relay 33 and stop powering to electrical bar 2, reminding user dress water overfill, overflow after avoiding water to seethe with excitement hurt sb.'s feelings, short circuit; When the hydraulic pressure detected does not have the settings higher than single-chip microcomputer 322, single-chip microcomputer 322 controls sound-producing device 34 to be stopped sending voice prompt, and closing relay 33 starts to power to electrical bar 2.
Certainly, the exemplary illustration of the above only the utility model typical apply, by the combination of same or similar technical characteristic and replacement, can form multiple concrete scheme, these schemes all drop within protection domain of the present utility model.
