Abstract
The utility model utilizes a common electronic watch as a timer. The utility model counts time by switching on or off parallelly connected switches arranged on two ends of a quartz resonator. The utility model has the advantages of simple structure, high precision, small size and low cost. The utility model can be widely applied to industry equipment and household electric appliances.
Description
The utility model relates to electronic timer.
Present timer is generally dynamo-electric timer and electronic timer, shortcomings such as volume is big, cost is high, complex structure that they exist, and also there are problems such as accuracy of timekeeping difference in dynamo-electric timer.
The purpose of this utility model is to utilize common accutron to make timer.
The purpose of this utility model is achieved in that the (K with the quartz resonator of primary electron table (4) two ends parallel connection
1) (2) conducting, (as Fig. 1), or with (the K of (4)
2) disconnect, (as Fig. 2), or a in (4) holds and power positive end is incorporated one into by (K
3) subcircuits (as Fig. 3) formed of (2), (3), or incorporate one into by (K at trimmer (9) two ends
4) subcircuits (as Fig. 4) formed of (2), (3), or seal in one by (K with power supply (8)
5) (3) parallel branch (as Fig. 4) of forming makes quartz resonator (4) failure of oscillation.
Fig. 1 to Fig. 5 is 5 embodiment, below in conjunction with description of drawings.(4) (5) (6) (8) (9) are primary electron table parts, and other is an external parts.When needing the equipment work of timing, by equipment control switch (K
1) disconnect the normal timing of electronic watch.Work shutdown switch (K
1) closure, the quartz resonator of timer (4) failure of oscillation and when stopping then, but this and former working time are still memorized by the counting logical circuit of electronic watch (5), working time next time can continue to add up with the working time last time, reaches the purpose of accumulative total working time.Can also disconnect (the K in the quartz resonator circuit in addition
2), or incorporate a circuit again into power positive end at a of quartz resonator end; Or incorporate a circuit again at trimmer (9) two ends; Or reduce these several ways of supply voltage, make the quartz resonator failure of oscillation, and reach the purpose of timing.LCD loses driving voltage and does not show when not working.Desire is observed the time that has added up, and pressing switch (2) can show.The time of accumulative total can by moon that shows, day, the morning (R), afternoon (P), the time, the branch conversion.As show 127P10:30, be scaled 27 * 24 * 12 * 10:30=670 hour 30 minutes, switch (6) be used for the control moon, day, morning and afternoon, the time, the branch Alternation Display.Switch (7) is used for zero clearing.Switch (1) can be the normally closed contact or the microswitch of circuit breaker or contactor, (3) impedor, and (9) are trimmer, (8) are direct supply.(K
2) (K
5) closure, (K
1), (K
3), (K
4) when opening time status.
The utility model is simple in structure, and timing is accurate, and volume is little, cost is low, can be widely used on industrial equipment and the household electrical appliance.
