Description

Technical Field

[0001] The present invention relates to the field of inkjet printing, in particular to an intelligent nozzle power-off protector. Background Art

[0002] Inkjet printers are widely used in many fields such as office printing, inkjet advertising, printing and dyeing. The core component, the printer nozzle, has the industry pain point of being most prone to clogging and damage. Part of the reason is that after the printer is finished working and the power is cut off, the nozzle that has been unused for a long time will produce ink precipitation and clog the filter in the nozzle. The ink in the tube cannot be completely drained. The less ink residue, the easier it is to dry. The printer nozzle is much smaller than a hair, and it is easier to clog when it dries into solid particles. Another part of the reason is that the nozzle at the bottom of the nozzle is dried and damaged, which seriously affects the normal use of the inkjet printer.

[0003] How to design an intelligent nozzle power-off protector with clever design and simple structure, which is designed to protect the inkjet printer from ink clogging the filter when the work is completed and the power is completely cut off, and to prevent the nozzle at the bottom of the nozzle from drying up and causing damage to the nozzle, when the nozzle is parked for a long time. This device is designed to protect the inkjet printer from ink clogging the filter when the work is completed and the power is completely cut off. It is a problem that needs to be solved at present. Summary of the Invention

[0004] In order to solve the industry pain point that the existing inkjet printer nozzles are most prone to clogging and damage, part of the reason is that after the printer is finished working and the power is cut off, the nozzles that have been unused for a long time will produce ink precipitation and clog the filter screen in the nozzle; another part of the reason is that the nozzle holes at the bottom of the nozzle are dried up and damaged, which seriously affects the normal use of the inkjet printer. The present invention provides an intelligent nozzle power-off protector to achieve the purpose of clever design, simple structure, scientific and reasonable, and effectively extend the service life of the printer nozzle.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an intelligent nozzle power-off protector, including an inkjet printer nozzle, an ink pump, an ink cartridge, a waste ink barrel, and also including an independent small power supply, a circulation time relay, a first relay, a second relay, a third relay, an ink extraction time end, a shutdown time end, a normally closed end, a normally open end and a mainboard ink extraction signal end. The independent small power supply controls the first relay, the second relay, and the third relay through the circulation time relay, and performs a circulation action according to the set shutdown time and ink extraction time.

[0006] As a further optimization solution of the above-mentioned intelligent nozzle power-off protector, the cycle time relay is provided with an ink extraction time terminal and a shutdown time terminal.

[0007] As a further optimization solution of the above-mentioned intelligent sprinkler head power-off protector, a normally closed terminal is provided on the second relay.

[0008] As a further optimization solution of the above-mentioned intelligent nozzle power-off protector, the third relay is provided with a normally open end and a mainboard ink pumping signal end.

[0009] As a further optimization solution of the above-mentioned intelligent nozzle power-off protector, the intelligent nozzle protector and the inkjet printer adopt a dual-connection and dual-control method for the ink pump.

[0010] As a further optimization solution of the above-mentioned intelligent sprinkler head power-off protector, when the host and the intelligent sprinkler head protector are operated and started at the same time, the second relay cuts off the circuit of the intelligent sprinkler head protector to achieve host priority.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present invention includes an inkjet printer nozzle, an ink pump, an ink cartridge, a waste ink barrel, and also includes an independent small power supply, a circulation time relay, a first relay, a second relay, a third relay, an ink extraction time end, a shutdown time end, a normally closed end, a normally open end and a mainboard ink extraction signal end. The independent small power supply controls the first relay, the second relay, and the third relay through the circulation time relay, and performs a circulation action according to the set shutdown time and ink extraction time.

[0013] 2. The intelligent nozzle protector of the present invention only controls the ink pump parts of the printer. The original printer can still control the original ink pump with priority. If it is operated incorrectly at the same time, the protector cuts off the power supply of the nozzle protector and becomes ineffective. In order to prevent the main control board and the expensive inkjet head from being accidentally damaged when the host is not working for a long time, a maintenance method of completely cutting off the power of the host is adopted.

[0014] Third, another beneficial effect of the present invention is that the ink in the ink tube of the entire machine can flow simultaneously during the ink pumping action, so that when the temperature is too high in summer, the remaining solid pigments in the tube will not clog the tube after the water in the tube evaporates, in addition to the nozzle. As the saying goes, running water does not stale, the ink will not solidify and evaporate during the flow process to clog the tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] As shown in the figure, the intelligent nozzle power-off protector includes an inkjet printer nozzle 1, an ink pump 2, an ink cartridge 3, a waste ink barrel 4, and also includes an independent small power supply 5, a circulation time relay 6, a first relay 7, a second relay 8, a third relay 9, an ink extraction time terminal 10, a shutdown time terminal 11, a normally closed terminal 12, a normally open terminal 13 and a mainboard ink extraction signal terminal 14. The independent small power supply 5 controls the first relay 7, the second relay 8, and the third relay 9 through the circulation time relay 6, and performs a circulation action according to the set shutdown time and ink extraction time.

[0020] The cycle time relay 6 is provided with an ink pumping time terminal 10 and a shutdown time terminal 11 .

[0021] The second relay 8 is provided with a normally closed terminal 12 .

[0022] The third relay 9 is provided with a normally open terminal 13 and a mainboard ink pumping signal terminal 14 .

[0023] The intelligent nozzle protector and the inkjet printer adopt a dual-connection and dual-control mode for the ink pump 2.

[0024] When the host and the intelligent nozzle protector are started at the same time, the second relay 8 cuts off the circuit of the intelligent nozzle protector to give priority to the host.

[0025] refer to Figure 1 and Figure 2 The assembly working process of the present invention is as follows: the independent small power supply 5 is turned on and performs an infinite cycle action according to the set shutdown time and ink extraction time through the cycle time relay 6. When the ink extraction time end 10 is actuated, it drives the first relay 7 to power the ink pump 2 for ink extraction maintenance work. Its working principle and effect are that the ink extraction action is performed before the ink is precipitated and the nozzle hole is dry, which can eliminate the precipitation and moisten the bottom of the nozzle, thereby avoiding damage to the nozzle. The role of the second relay 8 is that when the host is turned on, sometimes the intelligent nozzle protector is not turned off and the host is turned on at the same time to cause a conflict, the mainboard ink pump signal end 14 starts the third relay 9 to drive the ink pump 2 to work while starting the normally closed end 12 of the relay 8, cutting off the power supply of the intelligent nozzle protector to the ink pump 2, thereby preventing the host from damaging the board, and realizing dual control of the ink pump 2 by the host and the intelligent nozzle protector with the host taking priority.

[0026] refer to Figure 1 When the small power supply 5 and the mainboard ink pumping signal 14 are activated respectively, they supply power to the ink pump 2 respectively.

[0027] refer to Figure 2 When the ink pump signal terminal 14 on the mainboard is turned on, it only controls the second relay 8 and does not provide power to the ink pump 2. The normally closed terminal 12 of the second relay 8 cuts off the power supply to the cycle time relay 7. The two normally open terminals 13 of the second relay 8 respectively control the positive and negative poles of the power supplied by the small power supply 5 to connect to the ink pump 2. From this, it can be seen that there are two different power sources supplying the ink pump 2, namely the small power supply 5 and the ink pump signal terminal 14 on the mainboard.

[0028] The present invention has an ingenious design, a simple structure, and is scientific and reasonable. It effectively extends the service life of the printer nozzle and solves the industry pain point that the existing inkjet printer nozzles are most prone to clogging and damage. One reason is that after the printer is finished working and the power is cut off, the nozzles that have been unused for a long time will produce ink precipitation and clog the filter screen in the nozzle. Another reason is that the nozzle holes at the bottom of the nozzle are dried up and damaged, which seriously affects the normal use of the inkjet printer. For existing technologies, it has good market prospects and development space.

[0029] The preferred specific implementation modes and embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation modes and embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the concept of the present invention.
