Technical field
The present invention relates to a kind of sensing identifying device, the contactless sensing identification dress of more particularly, to a kind of printing consumables
Put.
Background technology
Printing consumables refers to the consumable products of printer.As common OfficeMate office partner, laser are beaten
Print machine consumptive material, toner cartridge;Ink-jet printer consumptive material, print cartridge;Impact printer consumptive material, ribbon cartridge, carbon dust, printing paper etc., beat
Print consumptive material industry industrial chain is followed successively by from upstream to downstream:Chemical raw material carbon dust (ink) toner cartridge (print cartridge) is beaten
Print machine.Industry participant can be divided into original-pack manufacturer and clone manufacturer.Terminal printer is durable goods, and the market demand is very huge
Greatly, but competition also very violent.
Sensor is receipt signal or the device stimulating and reacting, and it is another right to be converted into measured physical quantity or chemical quantity
The device that should export.For Automated condtrol, security device etc..When the input of a sensor and output form linear closing completely
When being, this sensor is exactly an ideal transducer.
Existing printing consumables sensing identifying device presence is contacted with consumptive material, easily consumptive material is polluted, sensing identification effect
Really poor, flimsy shortcoming, is therefore needed badly design one kind and is not contacted with consumptive material, consumptive material will not be polluted, sensing identification effect

Plate, fixed plate top is provided with spring, and spring top is provided with the second magnetic patch, and discharge nozzle external right side is provided with the second electromagnetic sensor, the
Two electromagnetic sensors and controller connect, so when liquid consumptive material is little, may will not get on blade it is impossible to drive first
Magnetic patch rotate, now liquid consumptive material flow down beat on the second magnetic patch, second magnetic patch decline, spring-compressed, the second electromagnetic sensing
Device senses electromagnetism, and then to controller, controller then controls printer to continue running to the first electromagnetic sensor feedback signal.As
Fruit does not have liquid consumptive material to flow down, then the second magnetic patch will not decline, and the second electromagnetic sensor can not sense electromagnetism, and then second
To controller, controller then controls printer to decommission to electromagnetic sensor feedback signal.
Because also including capacitance sensor, discharge nozzle external right side bottom is provided with capacitance sensor, capacitance sensor and control
Device processed connects, as long as so there being liquid consumptive material to flow down, capacitance sensor just can sense capacitance variations, then feeds back signal extremely
Controller, controller then controls printer to continue running.Flow down without liquid consumptive material, then capacitance sensor just can
Sense capacitance variations, then to controller, controller then controls printer to decommission to the second electromagnetic sensor feedback signal.
Because the material of liquid consumptive material case is plastics, it is difficult to make liquid consumptive material go bad.
Because the thickness of liquid consumptive material case is 1 centimetre, liquid consumptive material case is more robust.
Because spring is elastic component, more preferably, cushioning effect is more preferable for elasticity.
Because the material of fixed plate is stainless steel, fixed plate is difficult to get rusty, long service life.
