The invention can be illustrated by the following operating modes: when the nozzle of the ink-jet printer needs to be cleaned and maintained, the disassembled nozzle is only needed to be placed into the placing groove 2, the infrared lamp 5 is always in an electrified state in an initial state, light emitted by the infrared lamp 5 directly irradiates on the photosensitive resistor 6, the photosensitive resistor 6 receives strong illumination and large resistance, the photosensitive resistor 6 has large resistance, the current passing through the electromagnet 7 is small, the magnetic force on the electromagnet 7 is small, after the nozzle blocks the light emitted by the infrared lamp 5, the photosensitive resistor 6 receives weak illumination and small resistance, the current passing through the electromagnet 7 is increased, the magnetism generated by the electromagnet 7 is large, and the electromagnet 7 repels the same poles of the adjacent surfaces of the two magnetic sliders 9 after being electrified, so that the two magnetic sliders 9 can be pushed to move back to back;
the magnetic slide block 9 positioned above can move upwards instantly, so that the gas in the space above the magnetic slide block 9 positioned above the vertical cavity 8 is pushed into the annular air bag 4 through the short pipe, the annular air bag 4 is expanded inwards, and the sealing property in the sealed groove is ensured;
because the gas in the space below the magnetic slider 9 positioned below the vertical cavity 8 is exhausted to the outside through the thin tube 11, the outside gas enters the space below the magnetic slider 9 positioned above and below the vertical cavity 8 through the thick tube 12, and because the caliber of the thick tube 12 is five times that of the thin tube 11, the magnetic slider 9 positioned below is enabled to move downwards slowly, when the magnetic slider 9 moves downwards slowly and contacts with the two conducting strips 18, the conducting spring 29 and the air suction assembly 14 are powered on, after the conducting spring 29 is powered on, each coil can generate a magnetic field, the directions of the magnetic fields generated by each two adjacent coils are opposite, each two adjacent coils can attract each other, so that the conducting spring 29 is contracted, when the conducting spring 29 is contracted, the moving block 27 can move rightwards, so that the vertical tube 23 is conducted through the through hole 28;
at the moment, the operation of the air suction assembly 14 can enable the fan blades to rotate, so that the gas in the collecting cavity 19 is sucked into the air suction groove 13, the gas in the collecting cavity 19 is reduced, the air pressure is reduced, the gas in the placing groove 2 can enter the collecting cavity 19 under the action of atmospheric pressure, negative pressure can be formed in the placing groove 2, after the spray head is blocked by dried ink, a pressure difference is formed in the front and the back of the dried ink in the spray head, the dried ink in the spray head is sucked out, and the situation that the ink cannot be smoothly sprayed during next ink jet is avoided;
the operation of the air suction assembly 14 can enable the rotating rod to rotate, thereby driving the protruding rod 16 to rotate, because the protruding rod 16, the connecting rod is rotationally connected with the sliding block 17, thereby enabling the sliding block 17 to move up and down, the sliding block 17 moves down to enable the space above the sliding block 17 to be increased in the reciprocating cavity 15, the air pressure is reduced, thereby being capable of sucking the water in the liquid storage cavity 20 into the space above the sliding block 17 in the reciprocating cavity 15, when the sliding block 17 moves up, the space above the sliding block 17 in the reciprocating cavity 15 is reduced at the moment, the pressure is increased, the water above the sliding block 17 in the reciprocating cavity 15 can enter the transverse pipe 21, and then the cleaning liquid is sprayed to the surface of the spray head through the plurality of spray pipes 22, thereby removing the ink on the surface of the spray head, and avoiding the situation that the residual ink on the spray head can cause the uneven ink spraying of the next spray head;
when the magnetic sliding block 9 positioned below is separated from the two conducting strips 18, the conducting spring 29 and the air suction assembly 14 are powered off, under the action of the tension of the conducting spring 29, the moving block 27 is moved to the left, the vertical tube 23 is blocked again, after the air suction assembly 14 is powered off, the plurality of fan blades can still continue to rotate for a period of time due to inertia, certain cleaning liquid is continuously sprayed into the placing groove 2, the cleaning liquid can be gathered at the inner bottom of the placing groove 2, so that natural evaporation of the cleaning liquid can play a certain moisture-preserving role on the spray head along with the passage of time, the condition that the spray head is quickly blocked when the spray head is used again is avoided, and the service life of the spray head is prolonged;
when taking out the shower nozzle, the light of infrared lamp 5 shines on photo resistance 6 again this moment, photo resistance 6's resistance increases once more, the electric current through electro-magnet 7 reduces, thereby under two reset spring 10's elastic action, two magnetic sliding blocks 9 are relative motion, contract at annular gasbag 4 this moment, the magnetic sliding block 9 that is located the below shifts up the contact that can with two conducting strips 18, contact time is shorter, because the subassembly 14 that induced drafts can operate very short period of time, spout certain cleaning solution to the shower nozzle surface, thereby further promote the moisturizing effect of shower nozzle in subsequent use, conductive spring 29 circular telegram makes standpipe 23 switch on once more simultaneously, thereby make the remaining cleaning solution of standing groove 2 enter into and collect in the chamber 19.
Compared with the prior art, when the sprayer is placed in the placing groove 2, the annular air bag 4 expands to form a closed space below the placing groove 2, the air suction assembly 14 and the conductive spring 29 are powered on for a period of time, the air suction assembly 14 sucks air in the placing groove 2, so that negative pressure is formed to suck out dry ink in the sprayer, the situation that the ink cannot be smoothly sprayed during next ink spraying is avoided, meanwhile, the air suction assembly 14 drives the convex rod 16 to rotate, so that the sliding block 17 moves up and down, so that the cleaning solution is continuously sprayed to the surface of the sprayer, the ink on the surface of the sprayer is removed, the situation that the ink sprayed by the sprayer is uneven next time due to the residual ink on the sprayer is avoided, after the air suction assembly 14 is powered off, a plurality of fan blades can still continue to rotate for a period of time due to inertia, so that certain cleaning solution is continuously sprayed into the placing groove 2, these washing liquids can gather at the interior bottom of standing groove 2 to along with the time, the natural evaporation of washing liquid can play certain moisturizing effect to the shower nozzle, and the condition that the shower nozzle blockked up fast when avoiding reusing appears, thereby prolongs the live time of shower nozzle.
