Description
Technical field
The utility model relates to a kind of timer.
Background technology
The make charcoal setting of interval time and the time of making charcoal of oxygen probe has very significant effects for the usability and life-span of oxygen probe; And existing technology can only be in the operation of carbon control instrument the inside when setting two time periods; Because the parameter of instrument the inside is many; These two time periods accidentally will be given up other parameter when setting and revising, cause instrument to go wrong.
The utility model content
The purpose of the utility model provides a kind of timer, and is easy to use to overcome the deficiency of the above-mentioned aspect of existing product, simple to operate, and timing control accurately.
The purpose of the utility model is to realize through following technical scheme:
A kind of timer; Comprise timepiece body, the leading flank of said timepiece body is provided with control panel, and the upper left side of control panel is provided with relay indicating light and relay output indicator; The bottom of control panel is provided with some control knobs that are arranged in parallel, and the control knob top is provided with display screen; Be provided with Chronograph control device in the said timepiece body, Chronograph control device connects relay respectively circuit, frequency control circuit, for a long time device control circuit, tachometer gage control circuit, counter controling circuit and power supply is set.Said relay is provided with circuit and comprises single time-delay four bit time control relay circuits and dual-delay four bit time control relay circuits.Said frequency control circuit comprises unifrequency control circuit and bifrequency control circuit.Said counter controling circuit comprises reset circuit, suspends circuit and function selector circuit.
The beneficial effect of the utility model is: can well make charcoal to oxygen probe and carry out timing control, easy to use, simple to operate, timing control accurately.

Embodiment
Shown in Fig. 1-2; The described a kind of timer of the utility model embodiment; Comprise timepiece body 1, the leading flank of said timepiece body 1 is provided with control panel 11, and the upper left side of control panel 11 is provided with relay indicating light 111 and relay output indicator 112; The bottom of control panel 11 is provided with some control knobs that are arranged in parallel 113, and control knob 113 tops are provided with display screen 114; Be provided with Chronograph control device 12 in the said timepiece body 1, Chronograph control device 12 connects relay respectively circuit 121, frequency control circuit 122, for a long time device control circuit 123, tachometer gage control circuit 124, counter controling circuit 125 and power supply 126 is set.Said relay is provided with circuit 121 and comprises single time-delay four bit time control relay circuits 1211 and dual-delay four bit time control relay circuits 1212.Said frequency control circuit 122 comprises unifrequency control circuit 1221 and bifrequency control circuit 1222.Said counter controling circuit 125 comprises reset circuit 1251, suspends circuit 1252 and function selector circuit 1253.
During concrete the use, timer is to be used for controlling the device of interval time and the time of making charcoal of making charcoal, and it can be at any time, random setting and adjust this two time periods; Make charcoal interval time and the time of making charcoal of oxygen probe generally is to burn a charcoal in four hours, once burnt one minute, after configuring these two time periods by the timer initiation button; Making charcoal begins countdown interval time, and timer can be exported a signal and give relay, relay adhesive when timing finishes; At this moment solenoid valve is opened, and the air pump of making charcoal is simultaneously also started working, and the time of making charcoal begins countdown; After the time of making charcoal finished, solenoid valve cut out with the air pump of making charcoal automatically.This end cycle gets into the cycle of next round then, and the circulation that goes round and begins again down, thereby reaches the purpose of timer control.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection domain of the utility model.
