Side surface, i.e., insulator 200 simultaneously coated with conductive piece 100 lower surface and side surface.It is possible thereby to improve anti-overflow detection dress
Put the reliability of 10 anti-overflow detection function.
Specifically, as shown in figure 1, insulator 200 defines the unlimited accommodating chamber 220 in upper surface, conducting strip 100 is located at appearance
Receive in chamber 220, insulator 200 lower surface of coated with conductive piece 100 and side surface simultaneously, and conducting strip 100 upper surface from exhausted
Edge body 200 exposes, in order to be connected with electric capacity chip.
Advantageously, as shown in figure 1, the height of accommodating chamber 220 is more than the thickness of conducting strip 100, conducting strip 100 is located at receiving
Conducting strip 100, because the thickness of conducting strip 100 is smaller, can so be stably placed in insulator 200 by the bottom of chamber 220,
Prevent conducting strip 100 from deviating from the accommodating chamber 220 of insulator 200.
Alternatively, as shown in Fig. 2 the side wall of accommodating chamber 220 is outward-dipping from the bottom to top, need exist for being appreciated that, hold
The side wall of chamber 220 received refers to the integral side walls part of accommodating chamber 220, and is not necessarily referring to the side wall of accommodating chamber 220.It is possible thereby to side
Just under the liquid flow on the outer wall of insulator 200, it is to avoid liquid is sticked causes false judgment in anti-overflow detection means 10.
In some specific examples of the present utility model, as depicted in figs. 1 and 2, anti-overflow detection means 10 also includes master control
Chip 400.The power end of main control chip 400 is connected with default power supply, and default power supply is used to power for main control chip 400, master control
Chip 400 is communicated to receive the detection signal with capacitance detecting chips 300, and judged whether according to the detection signal
Generation spillover.
Advantageously, as depicted in figs. 1 and 2, resistance 500 is connected between capacitance detecting chips 300 and conducting strip 100.Electricity
Resistance 500 is used to be filtered processing to the capacitance variation amount signal of conducting strip 100, so as to play jamproof effect.
Wherein, the resistance value of resistance 500 is preferably 10 Ω to 10k Ω.
Alternatively, the thickness of insulator 200 is 1-10mm.Specifically, it is according to the decision formula of electric capacity：Can
Know, the thickness of insulator 200 is bigger, distance between polar plate d is bigger, in the case of steam bubble spill-out identical, the change of electric capacity
Change amount is smaller.So, the thickness of insulator 200 can be selected as the case may be.
