[0002] Varicose veins is a disease caused by blood stasis, weak venous walls, etc., and manifests as tortuosity and dilation of veins.

[0003] The treatment for varicose veins in the lower limbs includes fire needle bloodletting, which is a traditional Chinese medicine external treatment program. The main operation method is that the patient takes a sitting position with both lower limbs hanging naturally, and the selected acupoints are disinfected with iodine. Then the fire needle is burned red on an alcohol lamp and quickly inserted into the bulge of the vein. After the bloodletting is completed, it is pressed with a cotton ball to reduce the pressure in the vein and relieve the symptoms of varicose veins.

The operation process of this device is fully automated, avoiding possible mistakes and risks in manual operation. The operation process of the equipment can be repeated and standardized to ensure that the effect of each puncture is consistent and avoid fluctuations in treatment effects due to human factors.

[0021] By providing an external needle residue cleaning part, the blood stains remaining on the outer surface of the fire needle can be cleaned after the fire needle performs the puncture action, and the organic matter in the blood stains can be effectively removed, so that there are no obstacles on the surface of the fire needle. In the subsequent heating process, the heat can directly act on the surface of the fire needle to ensure that all pathogens are completely killed and the best disinfection effect is achieved. Therefore, the cleaned fire needle is more likely to meet the disinfection standard, reducing the risk of infection due to residual blood stains, ensuring that the fire needle is in a sterile state each time it is used, thereby improving the safety of the patient. There will be no blood stains remaining on the surface of the fire needle after cleaning, so no carbonized matter will be produced during the heating process, avoiding damage and influence of carbonized matter on the needle, and extending the service life of the needle. The surface of the cleaned fire needle is uniform, and the heat can be evenly distributed. Heat concentration or loss will not occur due to residual blood stains, ensuring that the fire needle is heated evenly and improving the disinfection efficiency.

[0022] By providing an angle adjustment component to adjust the angle of the bristles, the bristles can contact the surface of the fire needle from different angles, which helps to clean areas that are difficult to reach at a fixed angle. Combined with rotation in opposite directions, the bristles can cover various parts of the surface of the fire needle, reducing cleaning blind spots and ensuring that each area can be thoroughly cleaned. The surface of the fire needle may have slight unevenness or concave-convex changes. By adjusting the angle of the brush, it can better adapt to these surface changes and deeply clean dirt in gaps and fine structures. It can also optimize the contact mode between the bristles and the surface of the fire needle to avoid excessive friction of the bristles on a specific area, thereby reducing wear and passivation on the surface of the fire needle, which helps to maintain the integrity and smoothness of the surface of the fire needle and extend its service life. It can also ensure that the pressure of the contact between the bristles and the surface of the fire needle during cleaning is more uniform, avoiding surface damage caused by excessive force at a single point.

[0046] like Figures 1 to 14 As shown, an embodiment of the present invention provides an intelligent fire needle 556 bloodletting device for treating varicose veins of lower limbs, comprising a shell 1 and a cavity 11 opened inside the shell 1.

[0047] The housing 1 is connected with a lifting unit 3, and the lifting unit 3 is connected with a position adjustment part 4 for driving the position adjustment part 4 to lift and lower. The position adjustment part 4 includes an arc seat 41 connected with the lifting unit 3, two through slots 42 and a tooth slot 43 provided inside the arc seat 41, a bracket 45 slidably connected in the two through slots 42, a second motor 46 fixedly connected to the upper end of the bracket 45, a gear 44 rotatably connected to the inner wall of the bracket 45 and meshing with the tooth slot 43, and an output shaft of the second motor 46 is fixedly connected to one side of the gear 44;

[0048] The outer surface of the bracket 45 is also connected to a puncture unit 5, and the puncture unit 5 includes an infrared recognition part 51 fixedly connected to the upper end of the bracket 45, a movable seat 54 connected to the lower end of the bracket 45, and a puncture assembly 55 connected to the inside of the movable seat 54. The puncture assembly 55 includes a plate body 551 connected to the inner wall of the top of the movable seat 54, a fourth motor 552 and a first nozzle 557 fixedly connected to the lower end of the plate body 551, a second screw rod 553 rotatably connected to the lower end of the plate body 551, and a screw-connected A screw sleeve 554 is provided on the outside of the second screw rod 553, a fifth motor 555 is fixedly connected to one side of the screw sleeve 554, a chuck is rotatably connected to one side of the screw sleeve 554, a fire needle 556 is clamped in the chuck, a hollow frame 558 is fixedly connected to the lower end of the plate body 551, and an electric heating element 559 and a second nozzle 560 are respectively fixedly connected to both sides of the hollow frame 558, and the output shaft of the fifth motor 555 is fixedly connected to one side of the chuck, and the output shaft of the fourth motor 552 is fixedly connected to one end of the second screw rod 553. A three-way valve 7 is fixedly connected to the inner wall of the movable seat 54, and the two ports of the three-way valve 7 are respectively connected to the first nozzle 557 and the second nozzle 560, the upper end of the movable seat 54 is fixedly connected to the first pump body 9, the second pump body 10 and the liquid storage part 8, and the input end of the second pump body 10 passes through the movable seat 54 and extends into the interior of the movable cavity 564, the output end of the first pump body 9 is connected to the other port of the three-way valve 7, and the input end of the pump body is connected to the output end of the liquid storage part 8.

[0049] The lifting unit 3 includes a first screw rod 32 rotatably connected to the inner wall of the cavity 11 and two guide rods 33 fixedly connected to the inner wall of the cavity 11. The arc seat 41 is provided with guide grooves and wire grooves matching the guide rods 33 and the first screw rod 32. The upper end of the shell 1 is fixedly connected to a first motor 31, and the output shaft of the first motor 31 is fixedly connected to one end of the first screw rod 32.

[0050] A third motor 52 is fixedly connected to the inside of the bracket 45, and a first movable groove 53 is opened at the lower end of the bracket 45. The inner wall of the first movable groove 53 is rotatably connected to a screw rod four, and a movable seat 54 is slidably connected in the first movable groove 53 and screwed to the outside of the screw rod four. The output shaft of the third motor 52 is fixedly connected to one end of the screw rod four.

[0051] A groove 541 is also provided inside the movable seat 54, and two drainage ports are provided at the lower end of the movable seat 54, and two liquid storage tubes 542 are respectively screwed to the outside of the two drainage ports. A socket 2 is plugged into the shell 1, and a strap 21 is connected to one side of the socket 2. A guide groove 12 and a positioning groove 13 are provided on one side of the shell 1, and a guide block 22 and a positioning plate 23 matching the guide groove 12 and the positioning groove 13 are fixed to the outer surface of the socket 2.

[0052] By adopting the above technical solution, the socket 2 is pulled out from the shell 1, and the socket 2 is tied to the lower limb by the strap 21, and then the guide block 22 is inserted into the guide groove 12, so that the socket 2 is reinserted into the shell 1. At this time, the lower limb is wrapped by the shell 1 and the socket 2, and the first motor 31 can drive the first screw rod 32 to rotate, so as to adjust the height of the arc seat 41, the bracket 45 and the puncture unit 5. The second motor 46 can drive the gear 44 to rotate, and the gear 44 rotates in the tooth groove 43 to drive the bracket 45 to move on the arc seat 41 along the through groove 42, so as to adjust the axial position of the puncture unit 5, adjust the XY axis position of the puncture unit 5, move the infrared recognition unit 51 and identify the varicose vein area of ​​the lower limb (near infrared light can penetrate the skin and be absorbed by the oxygenated hemoglobin in the blood, so that the blood vessels appear as dark areas in the imaging.

[0053] The robot uses a near-infrared light source to illuminate the skin, and the reflected light captured by the sensor can generate an image of the vein. This is a mature existing technology and will not be described here. It can also be used in conjunction with ultrasonic imaging. Ultrasonic waves can penetrate the skin and tissues and reflect when encountering materials of different densities to form an image. The robot scans the target area through an ultrasonic probe and generates an image of the venous blood vessels based on the reflected ultrasonic signal. The combination of the two can improve the robot's adaptability to the veins of different patients and ensure accuracy and success rate). After identifying the veins in the varicose vein area, the position of the puncture unit 5 is adjusted so that the fire needle 556 can be directed toward the vein, and then the third motor 52 is controlled to work. The third motor 52 drives the screw rod 4 to rotate, thereby driving the movable seat 54 to move toward the lower limb, so that the opening of the movable seat 54 is attached to the outside of the lower limb. The first pump body 9 works to pump the bactericidal disinfectant into the second nozzle 560, and the second nozzle 560 sprays it on the skin of the lower limb, and then the fourth motor 552 is controlled to work. The fourth motor 552 can drive the second screw rod 553 to rotate, and the second screw rod 553 rotates to drive the screw sleeve 554 and the fire needle 556 moves in the direction of the lower limbs, and at the same time, the first pump body 9 can also pump the bactericidal disinfectant into the first nozzle 557. When the fire needle 556 moves to the spraying area of ​​the first nozzle 557, the first nozzle 557 sprays the bactericidal disinfectant on the outer surface of the fire needle 556. At the same time, the fourth motor 552 can also drive the fire needle 556 to rotate, which can ensure that each part on the outer surface of the fire needle 556 has enough time to contact with the disinfectant, thereby improving the disinfection effect. The rotation can also help remove any residues or contaminants that may be attached to the needle, thereby further improving the disinfection effect. The screw sleeve 554 can also drive the fire needle 556 to move, so that all surfaces of the fire needle 556 can be more evenly contacted with the disinfectant, ensuring that all parts of the outer surface of the fire needle 556 are properly sterilized and disinfected, and the fire needle 556 is disinfected.

[0054] like Figure 7As shown, the electric heating element 559 is located on one side of the hollow frame 558, and the center of the electric heating element 559 is hollow. When the fire needle 556 passes through the hollow part of the electric heating element 559, the electric heating element 559 can heat the fire needle 556 (generate heat through the resistance wire or other conductive materials when the current passes, and then transfer the heat to the fire needle 556), and perform high-temperature sterilization on the fire needle 556. It should be noted here that the fifth motor 555 can drive the fire needle 556 to rotate, so that the bactericidal disinfectant can be evenly sprayed on the outside of the fire needle 556. When the fire needle 556 is about to contact the skin, the fifth motor 555 stops working, and the fire needle 556 punctures the vein to achieve bloodletting. The blood left from the outside of the lower limb is collected through the groove 541 and the liquid storage tube 542 to achieve automated venous bloodletting operation, avoiding possible mistakes and risks in manual operation. The operation process of the equipment can be repeated and standardized to ensure that the effect of each puncture is consistent, avoiding fluctuations in the treatment effect due to human factors.

[0055] like Figures 6 to 8 As shown, the movable seat 54 is also connected to a needle residue cleaning part 56, and the needle residue cleaning part 56 includes a third screw rod 562 screwed on the plate body 551, a seat body 563 fixed on the inner wall of the movable seat 54, an active cavity 564 opened in the seat body 563, a seventh motor 565 fixed on one side of the seat body 563, a first rod body 566 rotatably connected to the inner wall of the active cavity 564, and bristles 567 connected to the first rod body 566, the output shaft of the seventh motor 565 is fixed to one end of the first rod body 566, the plate body 551 is slidably connected to the inner wall of the movable seat 54, and the upper end of the movable seat 54 is fixed to a sixth motor 561, and the output shaft of the sixth motor 561 is fixed to one end of the third screw rod 562.

[0056] By adopting the above technical solution, when the fire needle 556 completes the puncturing action, the fourth motor 552 works to drive the screw sleeve 554 and the fire needle 556 to move in a direction away from the lower limb. When the needle head of the fire needle 556 moves out of the electric heating element 559, the fourth motor 552 stops working, and the sixth motor 561 works to drive the third screw rod 562 to rotate, driving the plate body 551 to move downward, thereby driving the puncture assembly 55 to move downward, so that the fire needle 556 descends and the fire needle 556 and the screw sleeve are separated. The outer surface of the adjacent end of 554 contacts with the bristles 567, and the fifth motor 555 continues to work and drives the fire needle 556 to rotate, so that the fire needle 556 rotates 360°, ensuring that every part on the outer surface of the fire needle 556 can contact with the bristles 567. The seventh motor 565 works to drive the first rod body 566 and the bristles 567 to rotate. The rotation direction of the fire needle 556 is opposite to that of the first rod body 566, so as to clean the blood stains remaining on the outer surface of the fire needle 556.

[0057] like Figure 7As shown, the first nozzle 557 is installed at the lower end of the plate body 551 and moves up and down synchronously with the plate body 551. The first nozzle 557 is located above the left side of the bristles 567. When the fire needle 556 and the bristles 567 rotate and contact each other, the first nozzle 557 sprays a bactericidal disinfectant, and sprays the bristles 567 on the fire needle 556, thereby improving the cleaning effect of the bristles 567 on the fire needle 556, and can also sterilize and disinfect the bristles 567 and the fire needle 556. At this time, the fourth motor 552 continues to work to drive the fire needle 556 to move, so that the bristles 67 can gradually clean the outer surface of the fire needle 556, so that all surfaces of the fire needle 556 can contact the bristles 67, ensuring that all parts of the outer surface of the fire needle 556 are properly cleaned and effectively removed. Organic matter is removed so that there is no obstruction on the surface of the fire needle 556. In the subsequent heating process, the heat can directly act on the surface of the fire needle 556 to ensure that all pathogens are completely killed and the best disinfection effect is achieved. Therefore, the cleaned fire needle 556 is more likely to meet the disinfection standard, reducing the risk of infection due to residual blood, and ensuring that the fire needle 556 is in a sterile state each time it is used, thereby improving the safety of the patient. There will be no blood residue on the surface of the fire needle 556 after cleaning, so no carbonized matter will be produced during the heating process, avoiding damage and impact of carbonized matter on the needle, and extending the service life of the needle. The surface of the cleaned fire needle 556 is uniform, and the heat can be evenly distributed. Heat will not be concentrated or lost due to residual blood, ensuring that the fire needle 556 is heated evenly and improving the disinfection efficiency.

[0058] like Fig.10 and Fig.14 As shown, the first rod body 566 is internally connected to an angle adjustment assembly 57, and the angle adjustment assembly 57 includes a second movable groove 571 opened in the first rod body 566, a column 575 movably connected to the second movable groove 571, a second tooth key 576 opened on the outer surface of the column 575, and a second rod body 574 rotatably connected to one side of the column 575. A first electric push rod 573 is fixedly connected to one side of the seat body 563, and the telescopic end of the first electric push rod 573 passes through the seat body 563 and the first rod body 566 and is fixedly connected to the other end of the second rod body 574. The bristles 567 are rotatably connected in the second movable groove 571, and the outer surface of the bristles 567 is provided with a first tooth key 572 meshing with the second tooth key 576.

[0059] By adopting the above technical solution, when the first rod body 566 is rotating, the first electric push rod 573 can push the second rod body 574 and the column 575 to move inside the first rod body 566 when it is extended. When the column 575 moves, the second tooth key 576 on the outer surface of the column 575 will contact the first tooth key 572. Since the first tooth key 572 is arranged outside the bristles 567, when the second tooth key 576 moves in parallel, it can drive the first tooth key 572 and the end of the bristles 567 inside the second movable groove 571 to rotate clockwise in the second movable groove 571. When the first electric push rod 573 is retracted, it drives the column 575 to move, and the second tooth key 576 moves in the direction of the first electric push rod 573 and drives the end of the bristles 567 to rotate counterclockwise in the second movable groove 571 through the first tooth key 572, thereby realizing the change of the angle of the bristles 567. When the angle of the bristles 567 changes, the bristles 567 and the fire needle 55 6 The change in the contact angle can make the bristles 567 contact the surface of the fire needle 556 from different angles, which helps to clean those areas that are difficult to reach at a fixed angle. Combined with the rotation in the opposite direction, the bristles can cover various parts of the surface of the fire needle 556, reducing cleaning blind spots and ensuring that each area can be thoroughly cleaned. The surface of the fire needle 556 may have slight unevenness or concave-convex changes. By adjusting the angle of the bristles 567, it can better adapt to these surface changes and deeply clean the dirt in the gaps and fine structures. It can also optimize the contact mode between the bristles 567 and the surface of the fire needle 556 to avoid excessive friction of the bristles 567 on a specific area, thereby reducing the wear and passivation of the surface of the fire needle 556, which helps to maintain the integrity and smoothness of the surface of the fire needle 556 and extend its service life. It can also ensure that the pressure of the bristles 567 in contact with the 556 surface during cleaning is more uniform, avoiding surface damage caused by excessive force at a single point.

[0060] like Figure 6 , Figure 8 and Fig. 9 As shown, the outer surface of the seat body 563 is connected to a reciprocating unit 58, and the reciprocating unit 58 includes two extension seats 581 symmetrically fixed on both sides of the seat body 563, a third movable groove 582 opened in one of the extension seats 581, two groups of third tooth keys 583 symmetrically arranged on the inner wall of the third movable groove 582, an incomplete gear 584 rotatably connected to the inner wall of the third movable groove 582, and an eighth motor 585 fixed on the outer surface of one side of the movable seat 54, and the output shaft of the eighth motor 585 passes through the movable seat 54 and is fixed to one side of the incomplete gear 584, and the two extension seats 581 are slidably connected to the inner wall of the movable seat 54.

[0061] By adopting the above technical solution, the eighth motor 585 can drive the incomplete gear 584 to rotate, and the rotation of the incomplete gear 584 can intermittently contact the two sets of third tooth keys 583, thereby driving the extension seat 581 to move left and right. The left and right movement of the extension seat 581 can drive the bristles 567 to move laterally on the surface of the fire needle 556, further expanding the cleaning coverage. Combined with the rotation and angle adjustment of the bristles 567, this multi-dimensional movement can ensure that every part of the fire needle 556, including the edges and hard-to-reach areas, can be thoroughly cleaned. The left and right translation enables the bristles 567 to clean a larger surface area of ​​the fire needle in a single operation, thereby reducing the number of multiple rotations or adjustments required. This not only saves cleaning time, but also improves the overall cleaning efficiency.

[0062] like Figure 6 , Figure 7 , Figures 10 to 13 As shown, the movable seat 54 is also connected to a pasting unit 6, and the pasting unit 6 includes a second electric push rod 61 fixedly connected to the inner wall of the movable seat 54 and a guide seat 62 for guiding the telescopic end of the second electric push rod 61, a first suction cup 63 fixedly connected to the telescopic end of the second electric push rod 61, a flange 64 integrally formed at the center of one side of the first suction cup 63, a hemostatic patch 65 adsorbed on one side of the first suction cup 63, and a release paper 66 adhered to one side of the hemostatic patch 65.

[0063] The lower end of the movable seat 54 is also connected to a feeding part 67, and the feeding part 67 includes a box body 671 fixed to the lower end of the movable seat 54, a material box 676 clamped in the box body 671, a material cavity 677 opened in the material box 676, a feeding plate 678 slidably connected to the inner wall of the material cavity 677, a spring 679 located in the material cavity 677, a fourth electric push rod 674 fixed to the lower end of the box body 671, an electric clamp 675 slidably connected to the inside of the box body 671, a third electric push rod 672 fixed to one side of the box body 671, and a second suction cup 673 fixed to the telescopic end of the third electric push rod 672, and the telescopic end of the fourth electric push rod 674 is fixed to one side of the electric clamp 675, and the two ends of the spring 679 are respectively connected to the inner wall of the material cavity 677 and one side of the feeding plate 678.

[0064] By adopting the above technical solution, after the fire needle 556 is pierced and cleaned, the fire needle 556 is reset, and then the first motor 31 works to drive the first screw rod 32 to rotate, so that the movable seat 54 moves upward, and the third electric push rod 672 works to extend and drive the second suction cup 673 to move. Figure 7 and Fig.12It can be seen that a cavity is provided inside the box body 671, and the material box 676 is clamped in the cavity inside the box body 671, and the opening of the material box 676 is facing the second suction cup 673. When the third electric push rod 672 drives the second suction cup 673 to move toward the material box 676, the second suction cup 673 extends from the opening of the material box 676 into the material cavity 677, and one side of the second suction cup 673 is in contact with the anti-sticking paper 66 on one side of the hemostatic patch 65 that is arranged in advance and stored in the material cavity 677. The second suction cup 673 sucks one side of the anti-sticking paper 66 when it works. Since the hemostatic patches 65 in the material cavity 677 are stored in parallel, Therefore, each time the second suction cup 673 enters the material chamber 677, it can only contact the anti-adhesive paper 66 of one hemostatic patch 65, and absorbs one hemostatic patch 65 at a time. After the second suction cup 673 absorbs the anti-adhesive paper 66, the third electric push rod 672 works and contracts to drive the second suction cup 673 to move, so that the second suction cup 673 is removed from the material box 676. After the hemostatic patch 65 is taken out of the material chamber 677, the electric clamp 675 is located below the second suction cup 673, and the fourth electric push rod 674 works to drive the electric clamp 675 to extend and move in the direction of the second suction cup 673, so that the electric clamp 675 can contact the hemostatic patch 65. The electric clamp 675 clamps the bottom of the hemostatic patch 65, and then the electric clamp 675 works to clamp the bottom of the hemostatic patch 65. After the electric clamp 675 clamps the hemostatic patch 65, the fourth electric push rod 674 continues to work to drive the electric clamp 675 to move upward, so that the electric clamp 675 and the hemostatic patch 65 are moved out of the material box 676 and enter the movable seat 54 (the movable seat 54 is provided with a groove for the electric clamp 675 and the hemostatic patch 65 to pass through). After the fourth electric push rod 674 drives the hemostatic patch 65 to move so that the center of the hemostatic patch 65 is parallel to the center of the first suction cup 63, the second electric push rod 61 works to drive the first suction cup 63 to extend. The first suction cup 63 sucks the hemostatic patch 65, and then the electric clamp 675 cancels the clamping, the fourth electric push rod 674 contracts to drive the electric clamp 675 to descend and reset, and the second electric push rod 61 extends to drive the hemostatic patch 65 to move toward the skin, so that the center of the hemostatic patch 65 can be attached to the needle hole on the skin, and the flange 64 can stick the adhesive area of ​​the hemostatic patch 65 that is not covered by the anti-sticking paper 66 to the skin. Then the patient tears off the anti-sticking paper 66 at the edge of the hemostatic patch 65 by hand to make the adhesive area on the hemostatic patch 65 completely fit the skin, thereby realizing the automatic application operation of the hemostatic patch 65 to the needle hole.

[0065] The working process of the technical solution of the present invention is as follows:

[0066] The socket 2 is pulled out of the shell 1, and the socket 2 is tied to the lower limb by the strap 21, so that the socket 2 is reinserted into the shell 1. At this time, the lower limb is wrapped by the shell 1 and the socket 2. The first motor 31 can drive the first screw rod 32 to rotate, so as to adjust the height of the arc seat 41, the bracket 45 and the puncture unit 5. The second motor 46 can drive the gear 44 to rotate. The gear 44 rotates in the tooth groove 43 to drive the bracket 45 to move on the arc seat 41 along the through groove 42, so as to adjust the axial position of the puncture unit 5. The XY axis position of the puncture unit 5 is adjusted to move the infrared recognition unit 51 to identify the varicose vein area of ​​the lower limb, and the varicose vein area is identified. After the vein is inserted, the position of the puncture unit 5 is adjusted so that the fire needle 556 can face the vein, and then the third motor 52 is controlled to work, and the third motor 52 works to drive the screw rod 4 to rotate, thereby driving the movable seat 54 to move toward the lower limb, so that the opening of the movable seat 54 is attached to the outside of the lower limb, and the first pump body 9 works to pump the bactericidal disinfectant into the second nozzle 560, and the second nozzle 560 sprays it on the skin of the lower limb, and then the fourth motor 552 is controlled to work, and the fourth motor 552 works to drive the second screw rod 553 to rotate, and the second screw rod 553 rotates to drive the screw sleeve 554 and the fire needle 556 to move toward the direction of the lower limb, and at the same time, the first pump body 9 can also pump the bactericidal disinfectant into the first nozzle 557, The first nozzle 557 sprays it on the outer surface of the fire needle 556 to disinfect and sterilize the fire needle 556. At the same time, the electric heating element 559 heats the fire needle 556 to sterilize the fire needle 556 at high temperature. When the fire needle 556 is about to contact the skin, the fifth motor 555 stops working, and the fire needle 556 punctures the vein to achieve bloodletting. After the puncture, the fire needle 556 moves to the top of the bristles 567 and contacts the bristles 567. The seventh motor 565 drives the first rod body 566 and the bristles 567 to rotate. The fifth motor 555 drives the fire needle 556 to rotate. The rotation direction of the fire needle 556 is opposite to that of the first rod body 566, so as to clean the blood stains remaining on the outer surface of the fire needle 556. When the first rod body 566 is rotating, the first electric push rod 573 can drive the second rod body 574 and the column 575 to move inside the first rod body 566. When the column 575 moves, the second tooth key 576 cooperates with the first tooth key 572 to make the bristles 567 rotate in the second movable groove 571, and the angle of the bristles 567 is adjusted. The eighth motor 585 can drive the incomplete gear 584 to rotate. The rotation of the incomplete gear 584 can intermittently contact the two groups of third tooth keys 583 respectively, thereby driving the extension seat 581 to move left and right. The left and right movement of the extension seat 581 can drive the bristles 567 to move horizontally on the surface of the fire needle 556, further expanding the cleaning coverage range.
