Description

Technical Field

[0001] The present invention relates to the technical field of laser printing devices, and more specifically, to a laser printing device and a method thereof. Background Art

[0002] Laser printing technology occupies an important position in modern printing solutions with its high efficiency, high quality, and wide range of application scenarios. Whether in the office environment, professional applications, or home use, it has demonstrated its irreplaceable value. With the continuous progress of technology and the changing market demands, the future of laser printing technology will be even brighter, indicating more possibilities for innovation and development. Laser printing requires the use of laser printing devices.

[0003] Existing laser printers usually come with a toner cartridge, and the inside of the toner cartridge is provided with toner powder. When the laser printer is used for a long time, the toner powder in the toner powder tank becomes less and less. When the toner powder is exhausted, it is necessary to add toner powder to the toner cartridge in a timely manner. Before adding the toner powder, it is necessary to remove the toner cartridge from the inside of the printer, remove the sealing sleeve, insert the head of the toner powder cartridge with toner powder into the toner powder tank, and squeeze the toner powder cartridge by hand to make the toner powder enter the toner powder tank. After the toner powder is added, in order to make the toner powder in the printer evenly distributed, it is necessary to manually shake the toner cartridge. After the toner powder in the toner cartridge is evenly distributed, the toner cartridge is installed inside the printer. When adding toner powder to the toner powder tank, it is necessary to disassemble and install the toner cartridge back and forth, resulting in a relatively cumbersome process for adding toner powder, which is very inconvenient. It also needs to be manually shaken evenly, thereby affecting the printing efficiency of the laser printer. Summary of the Invention

[0004] The purpose of the present invention is to provide a laser printing device to solve the problems raised in the above background art:

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A laser printing device includes a printer body. Inside the printer body is provided a toner cartridge. Inside the toner cartridge is provided a toner powder tank. Inside the toner powder tank is movably connected a powder adding rod. Corresponding to the surface of the powder adding rod are provided a number of rotating grooves. Inside any one of the rotating grooves is rotatably connected a rotating block that matches it. Fixedly installed on the outer surface of the rotating block is a powder spraying head. Inside the inner surface of the rotating block is provided a through groove communicating with the powder spraying head. One end of the powder adding rod is fixedly installed with a sealing ring that matches the toner powder tank. Inserted inside the sealing ring is a quick-connect spray head. Fixedly connected to the surface of the printer body is a mounting bracket. Fixedly installed on the surface of the mounting bracket is a gas cylinder. A connecting pipe is fixedly connected between the gas cylinder and the quick-connect spray head. Fixedly installed on the surface of the connecting pipe is an electromagnetic valve. Threaded on the surface of the connecting pipe is a powder storage box.

[0007] By adopting the above technical solution, manually open the flap, thread the new toner cartridge onto the connecting pipe, the controller sends an instruction to the solenoid valve, after the solenoid valve opens, the internal gas of the gas cylinder is transported to the quick-connect nozzle through the connecting pipe, the gas flow carries the toner in the toner cartridge into the powder adding rod, the air flow entering the powder adding rod carries the toner into the through groove, and then discharges from the powder spraying head into the toner groove. When adding toner to the toner groove, there is no need to disassemble and assemble the toner cartridge back and forth, making the process of adding toner more convenient and fast, reducing the steps, and thus improving the printing efficiency of the laser printer.

[0009] By adopting the above technical solution, with the cooperation of the arc-shaped gear ring and the double-tooth plate, the rotation of the rotating block is more stable. The convex block rotates with the rotating shaft and squeezes the arc-shaped block and the guide rod to move towards the toner cartridge. At this time, the spring is compressed. The movement of the guide rod drives the double-tooth plate to move, and then makes the arc-shaped gear ring rotate to drive the rotating block and the powder spraying head to rotate. When the convex block rotates away from the arc-shaped block, the guide rod is reset under the action of the spring. With the continuous rotation of the convex block, the double-tooth plate reciprocates to drive the arc-shaped gear ring and the rotating block to swing horizontally back and forth, thereby realizing that the toner sprayed by the powder spraying head is evenly dispersed in the toner groove.

[0010] Preferably, the other end of the guide rod is fixedly installed with an arc-shaped block, the surface of the guide rod is sleeved with a spring, and both ends of the spring are fixedly connected with the surfaces of the arc-shaped block and the toner cartridge respectively. The arc-shaped block is elastically connected to the toner cartridge through the spring.

[0011] By adopting the above technical solution, the spring is used for the reset of the arc-shaped block.

[0012] Preferably, a rotating shaft is rotatably connected to the inner wall of the printer body, a convex block in contact with the arc-shaped block is fixedly installed on the surface of the rotating shaft, and a micro motor is fixedly installed on the inner wall of the printer body. The output end of the micro motor is fixedly connected with the rotating shaft.

[0013] By adopting the above technical solution, the micro motor provides power for the rotation of the rotating shaft.

[0014] Preferably, a controller is fixedly installed on the inner wall of the printer body. The solenoid valve is electrically connected to the controller through a wire, and the micro motor is electrically connected to the controller through a wire.

[0015] By adopting the above technical solution, the controller can control the opening and closing of the solenoid valve and the rotation of the micro motor.

[0016] Preferably, a flap is rotatably connected to the top surface of the printer body, a shaft is provided at the end of the flap, and the flap is rotatably connected to the printer body via the shaft.

[0017] By adopting the above technical solution and the design of the flip plate, it is easy to observe the working status of the toner cartridge.

[0018] Preferably, the number of the through grooves is three, the three through grooves are connected to each other, and the three through grooves are all connected to the powder spraying head.

[0019] Preferably, a corresponding inner wall of the printer body is provided with a card slot, and both end surfaces of the toner cartridge are fixedly connected with card blocks, and the toner cartridge is card-connected to the printer body through the cooperation between the card block and the card slot.

[0020] By adopting the above technical solution, when inspecting the toner cartridge, the flap is opened, the quick-connect nozzle is manually removed to separate the quick-connect nozzle from the toner cartridge, the toner cartridge is manually lifted up to disengage the card block from the card slot, and then the toner cartridge is taken out. After the inspection of the toner cartridge is completed, the card block and the card slot are engaged with each other, the toner cartridge is installed in the printer body, and the quick-connect nozzle is manually inserted into the sealing ring. The inspection process of the toner cartridge is very convenient and quick.

[0021] Preferably, the quick-connect nozzle is connected to the gas cylinder through a connecting pipe.

[0022] A method for using a laser printing device, the steps of which are as follows:

[0023] S1: When adding toner to the toner tank, stop the printer, open the flap manually, and install the new toner box onto the connecting pipe. At this time, the controller sends a command to the solenoid valve. After the solenoid valve is opened, the internal gas of the gas cylinder is transported to the quick-connect nozzle through the connecting pipe. During the transportation to the quick-connect nozzle, the gas flow carries the toner in the toner box into the quick-connect nozzle. At this time, the toner enters the powder adding rod along the airflow. At the same time as the controller sends a command to the solenoid valve, the controller supplies power to the micro motor, and the micro motor rotates with the shaft. At this time, the convex block follows the shaft to rotate and squeezes the arc block and the guide rod to move toward the toner drum. At this time, the spring is compressed, and the movement of the guide rod drives the double tooth plate to move, thereby causing the arc gear ring to rotate and drive the rotating block and the powder spraying head to rotate. The airflow entering the powder adding rod carries the toner into the through groove, and then is discharged from the powder spraying head to the toner tank;

[0024] S2: When the convex block rotates and separates from the arc block, the guide rod is reset by the spring. With the continuous rotation of the convex block, the double tooth plate reciprocates and the arc gear ring and the rotating block swing back and forth horizontally, thereby achieving uniform dispersion of the powder sprayed by the powder spray head in the powder drum tank;

[0025] S3: When the toner cartridge is used for a long time, it needs to be overhauled to ensure its normal use. When overhauling the toner cartridge, open the flap, manually remove the quick-connect nozzle, so that the quick-connect nozzle is separated from the toner cartridge, manually lift the toner cartridge upward so that the latch disengages from the card slot, and then remove the toner cartridge. When the inspection of the toner cartridge is completed and the latch and the card slot are engaged with each other, the toner cartridge is installed into the printer body at this time, and then manually insert the quick-connect nozzle into the sealing ring to complete the overhaul of the toner cartridge.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1) When the laser printing device is in use, by manually opening the flap, the new powder storage cartridge is threadedly installed on the connecting pipe. The controller sends an instruction to the solenoid valve. After the solenoid valve is opened, the internal gas of the gas cylinder is conveyed to the quick-connect nozzle through the connecting pipe. The flowing gas carries the toner powder in the powder storage cartridge into the powder adding rod. The airflow entering the interior of the powder adding rod carries the toner powder into the through groove, and then discharges it from the powder spraying head into the toner powder tank. When adding toner powder to the toner powder tank, there is no need to disassemble and assemble the toner cartridge back and forth, making the process of adding toner powder more convenient and fast, reducing the steps, and thus improving the printing efficiency of the laser printer.

[0028] 2) When the laser printing device is in use, the convex block rotates along with the rotating shaft and squeezes the arc-shaped block and the guide rod to move towards the toner cartridge. At this time, the spring is compressed. The movement of the guide rod drives the double-tooth plate to move, and then makes the arc-shaped gear ring rotate to drive the rotating block and the powder spraying head to rotate. When the convex block rotates and disengages from the arc-shaped block, the guide rod returns to its original position under the action of the spring. With the continuous rotation of the convex block, the double-tooth plate reciprocates to drive the arc-shaped gear ring and the rotating block to swing horizontally back and forth, thereby realizing that the toner powder ejected from the powder spraying head is evenly dispersed in the toner powder tank.

[0029] 3) When the laser printing device is in use, when overhauling the toner cartridge, open the flap, manually remove the quick-connect nozzle, so that the quick-connect nozzle is separated from the toner cartridge, manually lift the toner cartridge upward so that the latch disengages from the card slot, and then remove the toner cartridge. When the inspection of the toner cartridge is completed and the latch and the card slot are engaged with each other, the toner cartridge is installed into the printer body at this time, and then manually insert the quick-connect nozzle into the sealing ring. The overhaul process of the toner cartridge is very convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

The toner cartridge 2 is a conventional toner cartridge in the prior art that can be refilled with toner powder. Inside the toner cartridge 2, there is a toner powder chamber 3. There is a gap at the position where the toner powder chamber 3 is used. The toner powder chamber 3 is used to store toner powder. Inside the toner powder chamber 3, there is a powder adding rod 4 movably connected. The powder adding rod 4 is used for guiding the flow of toner powder. Corresponding to the surface of the powder adding rod 4, there are a number of rotating grooves 5 opened. Inside any one of the rotating grooves 5, there is a rotating block 6 rotatably connected thereto that matches it. On the outer surface of the rotating block 6, there is a powder spraying head 8 fixedly installed. The powder spraying head 8 is used to spray the toner powder towards the toner powder chamber 3. Inside the inner surface of the rotating block 6, there is a through groove 9 communicating with the powder spraying head 8. One end of the powder adding rod 4 is fixedly installed with a sealing ring 7 that matches the toner powder chamber 3. The function of the sealing ring 7 is to prevent the reverse flow of toner powder. Inside the sealing ring 7, there is a quick-connect spray head 10 inserted. On the surface of the printer body 1, there is a mounting bracket 11 fixedly connected. On the surface of the mounting bracket 11, there is a gas cylinder 12 fixedly installed. The gas cylinder 12 is used to provide air flow. Between the gas cylinder 12 and the quick-connect spray head 10, there is a connecting pipe 13 fixedly connected. On the surface of the connecting pipe 13, there is an electromagnetic valve 14 fixedly installed. The electromagnetic valve 14 is a controllable electromagnetic lock in the prior art. Threadedly connected to the surface of the connecting pipe 13 is a powder storage box 15. The powder storage box 15 is used to store toner powder. By manually opening the flap 17 and threadedly installing a new powder storage box 15 onto the connecting pipe 13, the controller 16 sends an instruction to the electromagnetic valve 14. After the electromagnetic valve 14 is opened, the gas inside the gas cylinder 12 is conveyed through the connecting pipe 13 to the quick-connect spray head 10. The flowing gas carries the toner powder in the powder storage box 15 into the powder adding rod 4. The air flow entering the inside of the powder adding rod 4 carries the toner powder into the through groove 9, and then discharges it from the powder spraying head 8 into the toner powder chamber 3. When adding toner powder to the toner powder chamber 3, there is no need to disassemble and assemble the toner cartridge 2 back and forth, making the process of adding toner powder more convenient and fast, reducing the steps, and thereby improving the printing efficiency of the laser printer.

[0042] On the surface of any one of the rotating blocks 6, there is an arc-shaped gear ring 18 fixedly connected. At the other end of the toner cartridge 2, there is a guide rod 20 slidably connected. The guide rod 20 guides the movement of the double-tooth plate 19. One end of the guide rod 20 is fixedly connected with a double-tooth plate 19 that meshes with the arc-shaped gear ring 18. With the cooperation of the arc-shaped gear ring 18 and the double-tooth plate 19, the rotation of the rotating block 6 becomes more stable. The convex block 24 rotates along with the rotating shaft 23 and squeezes the arc-shaped block 21 and the guide rod 20 to move towards the toner cartridge 2. At this time, the spring 22 is compressed. The movement of the guide rod 20 drives the movement of the double-tooth plate 19, and then makes the arc-shaped gear ring 18 rotate, driving the rotating block 6 and the powder spraying head 8 to rotate. When the convex block 24 rotates and disengages from the arc-shaped block 21, the guide rod 20 is reset under the action of the spring 22. With the continuous rotation of the convex block 24, the double-tooth plate 19 reciprocates, driving the arc-shaped gear ring 18 and the rotating block 6 to swing horizontally back and forth, thereby realizing that the toner powder sprayed by the powder spraying head 8 is evenly dispersed in the toner powder chamber 3.

[0043] At the other end of the guide rod 20, an arc-shaped block 21 is fixedly installed. A spring 22 is sleeved on the surface of the guide rod 20. The two ends of the spring 22 are respectively fixedly connected to the surfaces of the arc-shaped block 21 and the toner cartridge 2. The arc-shaped block 21 is elastically connected to the toner cartridge 2 through the spring 22, and the spring 22 is used for the reset of the arc-shaped block 21.

[0044] A rotating shaft 23 is rotatably connected to the inner wall of the printer body 1. A convex block 24 in contact with the arc-shaped block 21 is fixedly installed on the surface of the rotating shaft 23. A micro motor 25 is fixedly installed on the inner wall of the printer body 1. The micro motor 25 is a conventional electric motor in the prior art. The output end of the micro motor 25 is fixedly connected to the rotating shaft 23, and the micro motor 25 provides power for the rotation of the rotating shaft 23.

[0045] A controller 16 is fixedly installed on the inner wall of the printer body 1. The solenoid valve 14 is electrically connected to the controller 16 through a wire. The micro motor 25 is electrically connected to the controller 16 through a wire. The controller 16 is a conventional controller 16 in the prior art, and the controller 16 can control the switch of the solenoid valve 14 and the rotation of the micro motor 25.

[0046] A flap 17 is rotatably connected to the top surface of the printer body 1. A shaft is provided at the end of the flap 17. The flap 17 is rotatably connected to the printer body 1 through the shaft. The design of the flap 17 facilitates observing the working state of the toner cartridge 2.

[0047] The number of the through grooves 9 is three. The three through grooves 9 communicate with each other, and all the three through grooves 9 are communicated with the powder spraying head 8.

[0048] A clamping groove 26 is formed on the corresponding inner wall of the printer body 1. Clamping blocks 27 are fixedly connected to both ends of the toner cartridge 2. The toner cartridge 2 is clamped to the printer body 1 through the cooperation of the clamping blocks 27 and the clamping groove 26. When overhauling the toner cartridge 2, open the flap 17, manually remove the quick-connect nozzle 10 to separate the quick-connect nozzle 10 from the toner cartridge 2, manually lift the toner cartridge 2 upward so that the clamping block 27 disengages from the clamping groove 26, and then take out the toner cartridge 2. When the inspection of the toner cartridge 2 is completed and the clamping block 27 is engaged with the clamping groove 26, at this time, the toner cartridge 2 is installed into the printer body 1, and then manually insert the quick-connect nozzle 10 into the sealing ring 7. The overhaul process of the toner cartridge 2 is very convenient and fast.

[0049] The quick-connect nozzle 10 is communicated with the gas cylinder 12 through a connecting pipe 13.

[0050] Steps of using the present invention: When using this laser printing device, when adding toner to the drum powder tank 3, the operation of the printer body 1 is stopped, the flap 17 is manually opened, and a new toner cartridge 15 is threadedly installed on the connecting pipe 13. At this time, the controller 16 issues an instruction to the solenoid valve 14. After the solenoid valve 14 is opened, the internal gas of the gas cylinder 12 is transported to the quick-connect nozzle 10 through the connecting pipe 13. During the transportation to the quick-connect nozzle 10, the gas flow carries the toner in the toner cartridge 15 into the quick-connect nozzle 10. At this time, the toner enters the powder adding rod 4 along with the air flow. At the same time as the controller 16 issues an instruction to the solenoid valve 14, the controller 16 supplies power to the micro motor 25. The micro motor 25 rotates to drive the rotating shaft 23 to rotate. At this time, the convex block 24 rotates along with the rotating shaft 23 to squeeze the arc-shaped block 21 and the guide rod 20 to move towards the direction of the selenium drum 2. At this time, the spring 22 is compressed. The movement of the guide rod 20 drives the double-tooth plate 19 to move, thereby causing the arc-shaped gear ring 18 to rotate to drive the rotating block 6 and the powder spraying head 8 to rotate. The air flow entering the powder adding rod 4 carries the toner into the through groove 9, and then discharges from the powder spraying head 8 into the drum powder tank 3. When the convex block 24 rotates and disengages from the arc-shaped block 21, the guide rod 20 is reset under the action of the spring 22. With the continuous rotation of the convex block 24, the double-tooth plate 19 reciprocates to drive the arc-shaped gear ring 18 and the rotating block 6 to swing reciprocally in the horizontal direction, thereby realizing that the toner sprayed by the powder spraying head 8 is evenly dispersed in the drum powder tank 3. When the selenium drum 2 is used for a long time, the selenium drum 2 needs to be repaired to ensure the normal use of the selenium drum 2. When repairing the selenium drum 2, the flap 17 is opened, the quick-connect nozzle 10 is manually removed to separate the quick-connect nozzle 10 from the selenium drum 2, and the selenium drum 2 is manually lifted upward so that the clamping block 27 disengages from the clamping groove 26, and then the selenium drum 2 is taken out. When the inspection of the selenium drum 2 is completed and the clamping block 27 is engaged with the clamping groove 26, at this time, the selenium drum 2 is installed in the printer body 1, and then the quick-connect nozzle 10 is manually inserted into the sealing ring 7 to complete the repair of the selenium drum 2. This solution opens the flap 17 manually, threadedly installs a new toner cartridge 15 on the connecting pipe 13, the controller 16 issues an instruction to the solenoid valve 14. After the solenoid valve 14 is opened, the internal gas of the gas cylinder 12 is transported to the quick-connect nozzle 10 through the connecting pipe 13. The gas flow carries the toner in the toner cartridge 15 into the powder adding rod 4. The air flow entering the powder adding rod 4 carries the toner into the through groove 9, and then discharges from the powder spraying head 8 into the drum powder tank 3. When adding toner to the drum powder tank 3, it is not necessary to disassemble and assemble the selenium drum 2 back and forth, making the process of adding toner more convenient and fast, reducing the steps, and thus improving the printing efficiency of the laser printer;The convex block 24 rotates following the rotating shaft 23 to squeeze the arc-shaped block 21 and the guide rod 20 to move towards the direction of the drum 2. At this time, the spring 22 is compressed. The movement of the guide rod 20 drives the double-tooth plate 19 to move, thereby causing the arc-shaped gear ring 18 to rotate and drive the rotating block 6 and the powder spraying head 8 to rotate. When the convex block 24 rotates and disengages from the arc-shaped block 21, the guide rod 20 is reset under the action of the spring 22. With the continuous rotation of the convex block 24, the double-tooth plate 19 reciprocates to drive the arc-shaped gear ring 18 and the rotating block 6 to swing reciprocally in the horizontal direction, thereby realizing that the powder sprayed by the powder spraying head 8 is evenly dispersed in the powder drum groove 3. When overhauling the drum 2, open the flap 17, manually remove the quick-connect nozzle 10, so that the quick-connect nozzle 10 is separated from the drum 2, manually lift the drum 2 upwards, so that the clamping block 27 disengages from the clamping groove 26, and then take out the drum 2. When the inspection of the drum 2 is completed and the clamping block 27 and the clamping groove 26 are mutually clamped, at this time, the drum 2 is installed into the printer body 1, and then manually insert the quick-connect nozzle 10 into the sealing ring 7. The overhaul process of the drum 2 is very convenient and fast.

[0051] A method for using a laser printing device, the steps are as follows:

[0052] S1: When adding powder to the powder drum groove 3, stop the operation of the printer body 1, manually open the flap 17, threadedly install the new powder storage box 15 onto the connecting pipe 13. At this time, the controller 16 sends an instruction to the solenoid valve 14. After the solenoid valve 14 is opened, the internal gas of the gas cylinder 12 is transported to the quick-connect nozzle 10 through the connecting pipe 13. During the transportation to the quick-connect nozzle 10, the gas flow drives the powder in the powder storage box 15 into the quick-connect nozzle 10. At this time, the powder enters the powder adding rod 4 along with the air flow. At the same time as the controller 16 sends an instruction to the solenoid valve 14, the controller 16 supplies power to the micro motor 25. The micro motor 25 rotates to drive the rotating shaft 23 to rotate. At this time, the convex block 24 rotates following the rotating shaft 23 to squeeze the arc-shaped block 21 and the guide rod 20 to move towards the direction of the drum 2. At this time, the spring 22 is compressed. The movement of the guide rod 20 drives the double-tooth plate 19 to move, thereby causing the arc-shaped gear ring 18 to rotate and drive the rotating block 6 and the powder spraying head 8 to rotate. The air flow entering the powder adding rod 4 drives the powder into the through groove 9, and then is discharged from the powder spraying head 8 into the powder drum groove 3.

[0053] S2: When the convex block 24 rotates and disengages from the arc-shaped block 21, the guide rod 20 is reset under the action of the spring 22. With the continuous rotation of the convex block 24, the double-tooth plate 19 reciprocates to drive the arc-shaped gear ring 18 and the rotating block 6 to swing reciprocally in the horizontal direction, thereby realizing that the powder sprayed by the powder spraying head 8 is evenly dispersed in the powder drum groove 3.

[0054] S3: When the toner cartridge 2 is used for a long time, it is necessary to repair the toner cartridge 2 to ensure its normal use. When repairing the toner cartridge 2, open the flap 17, manually remove the quick-connect nozzle 10, so that the quick-connect nozzle 10 is separated from the toner cartridge 2, manually lift the toner cartridge 2 upward so that the latch 27 disengages from the card slot 26, and then take out the toner cartridge 2. When the inspection of the toner cartridge 2 is completed and the latch 27 and the card slot 26 are engaged with each other, at this time, the toner cartridge 2 is installed in the printer body 1, and then manually insert the quick-connect nozzle 10 into the sealing ring 7 to complete the repair of the toner cartridge 2.

At this time, the controller (16) sends a command to the solenoid valve (14). After the solenoid valve (14) is opened, the internal gas of the gas cylinder (12) is transported to the quick-connect nozzle (10) through the connecting pipe (13). During the transportation process to the quick-connect nozzle (10), the gas flow carries the toner in the toner storage box (15) into the quick-connect nozzle (10). At this time, the toner enters the powder adding rod (4) along the air flow, and the controller (16) sends a command to the solenoid valve (14). 14) at the same time as issuing the command, the controller (16) supplies power to the micro motor (25), the micro motor (25) rotates and drives the rotating shaft (23) to rotate, at this time the convex block (24) follows the rotating shaft (23) to rotate and squeeze the arc block (21) and the guide rod (20) to move in the direction of the toner cartridge (2), at this time the spring (22) is compressed, the movement of the guide rod (20) drives the double tooth plate (19) to move, and then the arc gear ring (18) rotates and drives the rotating block (6) and the powder spraying head (8) to rotate, the airflow entering the powder adding rod (4) drives the drum powder into the through groove (9), and then is discharged from the powder spraying head (8) into the drum powder tank (3); S2: When the convex block (24) rotates and disengages from the arc block (21), the guide rod (20) is reset by the action of the spring (22). As the convex block (24) rotates continuously, the double tooth plate (19) reciprocates and causes the arc gear ring (18) and the rotating block (6) to swing back and forth in the horizontal direction, thereby achieving that the powder sprayed by the powder spraying head (8) is evenly dispersed in the powder spraying tank (3); S3: When the toner cartridge (2) is used for a long time, it is necessary to inspect and repair the toner cartridge (2) to ensure the normal use of the toner cartridge (2). When inspecting the toner cartridge (2), the flap (17) is opened, and the quick-connect nozzle (10) is manually removed to separate the quick-connect nozzle (10) from the toner cartridge (2). The toner cartridge (2) is manually lifted upward to disengage the card block (27) from the card slot (26), and then the toner cartridge (2) is taken out. After the inspection of the toner cartridge (2) is completed, the card block (27) and the card slot (26) are engaged with each other. At this time, the toner cartridge (2) is installed in the printer body (1), and the quick-connect nozzle (10) is manually inserted into the sealing ring (7) to complete the inspection of the toner cartridge (2).
