Abstract
The utility model relates to the technical field of spinning printers, in particular to a device for automatically detecting ink and damage of an ink cartridge, which comprises a microprocessor and a photoelectric sensor, wherein the photoelectric sensor is electrically connected with an optical-coupling circuit, the optical-coupling circuit is electrically connected with a numerical control analogue switch, and the numerical control analogue switch is electrically connected with the microprocessor. The device can detect whether ink is left in the ink cartridge and whether the ink cartridge is damaged by directly detecting whether the ink is sprayed and printed on the paper, and is accurate, stable and reliable in judgment. Compared with a commonly adopted method that software is utilized to calculate whether the ink is left in the ink cartridge, the detecting method of the device has higher accuracy and can judge whether the ink cartridge has fault.
Description
Technical field
The utility model relates to weaving printer technology field, the inkless and damage automatic detection device of especially a kind of print cartridge.
Background technology
The weaving printer has carried out better combination by and automatic control technology synthetic with the higher computer of technology content, and the problem of the position that hand-printing ran into skew has been avoided in zone and the position that can point-device aligning need print.Owing to reasons such as use, misoperation, maintenance some phenomena of the failure occur through regular meeting, for example 1, ink marks rareness when printing, writing is beyond recognition to printer; 2, be shown as under the state that still has ink at the ink indicator lamp and but do not have ink when printing; 3, (jet orifice is stopped up, heating resistor damage etc.) appears damaging in print cartridge, can't print.Existing method is to calculate print cartridge by software to have or not ink, but because software is provided with improperly, tends to the situation that occurs judging by accident, thereby influence the operate as normal of printer, has reduced operating efficiency.
The utility model content
Be provided with improperly in order to overcome existing because software, tend to occur judging by accident the deficiency that print cartridge has or not the situation of ink, the utility model provides a kind of print cartridge inkless and damage automatic detection device.
The technical scheme that its technical problem that solves the utility model adopts is: the inkless and damage automatic detection device of a kind of print cartridge, this device comprises microprocessor and photoelectric sensor, described photoelectric sensor is electrically connected photoelectric coupled circuit, described photoelectric coupled circuit is electrically connected digital control analog switch, and described digital control analog switch is electrically connected microprocessor.
According to another embodiment of the present utility model, comprise that further described digital control analog switch is CD4051.
The beneficial effects of the utility model are, whether spray printing detects print cartridge to the mode on the paper to the utility model has or not ink and print cartridge whether to damage accuracy of judgement, reliable and stable by direct detection ink.Have or not the mode of ink to compare with calculating print cartridge by software usually, the higher degree of accuracy is arranged, and can judge that print cartridge has fault-free.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a theory diagram of the present utility model.
The specific embodiment
As Fig. 1 is theory diagram of the present utility model, inkless and the damage automatic detection device of a kind of print cartridge, this device comprises microprocessor and photoelectric sensor, described photoelectric sensor is electrically connected photoelectric coupled circuit, described photoelectric coupled circuit is electrically connected digital control analog switch, and described digital control analog switch is electrically connected microprocessor.Described digital control analog switch is CD4051.
Photoelectric sensor is used to gather the black blockage information of print cartridge spray printing to the paper; Microprocessor is used to judge print cartridge has or not ink and print cartridge whether to damage; Photoelectric coupled circuit has been avoided the interference between the signal of telecommunication and the optical signal.
Operation principle: this device is gathered the black blockage information of print cartridge spray printing to the paper by photoelectric sensor, this signal is sent to microprocessor by photoelectric coupled circuit and digital control analog switch, microprocessor judges print cartridge has or not ink and print cartridge whether to damage after handling through signals such as filtering.The situation that corresponding print cartridge has or not ink or print cartridge to damage, the corresponding passage of digital control analog switch conducting wherein is connected by photoelectric coupled circuit between photoelectric sensor and the digital control analog switch, avoids photoelectric sensor to influence the operate as normal of other circuit.
The advantage of this device: by the direct-detection ink whether spray printing detect print cartridge to the mode on the paper and have or not ink and print cartridge whether to damage (jet orifice is stopped up, heating resistor damage etc.), accuracy of judgement, reliable and stable. Have or not the mode of ink to compare with usually calculating print cartridge by software, the higher degree of accuracy is arranged, and can judge that print cartridge has fault-free.
Claims (2)
