The front end of the purification bin 2 is the air inlet end, and the rear end of the purification bin 2 is the air outlet end;

[0040] Specifically, the self-priming air purification structure includes an angle-adjustable suction assembly, a shunt grille 3, a HEPA filter element 4, an activated carbon filter element 5, and a fan plate 6 that are sequentially inserted into the purification bin 2 from front to back, and a suction fan 7 fixedly assembled on the fan plate 6;

[0041] Furthermore, the angle-adjustable suction assembly includes a suction pipe 8 penetrating through the inner wall of the front end of the purification bin 2 through a sealed bearing, a suction hood 9 fixedly communicated with the bottom end of the suction pipe 8, an installation cover 10 fixedly connected to the outer wall of the front end of the purification bin 2, a stepper motor 11 fixedly installed on the side wall of the installation cover 10, a worm 12 fixedly sleeved on the output shaft of the stepper motor 11, and a worm gear 13 fixedly sleeved on the suction pipe 8.

[0042] Specifically, the electric lifting cover includes two electric push rods 14 symmetrically fixed on the outer wall of one side of the purification bin 2, two connecting blocks 15 fixed on the telescopic ends of the two electric push rods 14, and the same sealed bin cover 16 fixedly connected to the outer walls of the two connecting blocks 15;

[0043] Furthermore, a hatch for disassembly is provided at the top of the purification chamber 2, and the sealing hatch cover 16 is adapted to the hatch. Then, by controlling the two electric push rods 14 to lift the sealing hatch cover 16 to the highest position, the shunt grille 3, HEPA filter element 4, activated carbon filter element 5, and fan board 6 inserted inside can be disassembled and maintained. After the disassembly and maintenance are completed, by controlling the two electric push rods 14 to lower the sealing hatch cover 16 to close, the shunt grille 3, HEPA filter element 4, activated carbon filter element 5, and fan board 6 can be tightly sealed to ensure the stability of the installation;

[0044] The working principle of this embodiment: First, the stepping motor 11 drives the worm 12 to rotate. Subsequently, the worm gear 13 meshed with the worm 12 will drive the suction pipe 8 to rotate, thereby facilitating the flexible adjustment of the working angle of the suction hood 9 connected to one end of the suction pipe 8, which helps to improve the suction effect;

[0045] Secondly, due to the suction force generated by the operation of the suction fan 7, the suction hood 9 sucks the polluted gas generated during the painting process into the purification chamber 2. The polluted gas will be evenly diffused to the surface of the HEPA filter element 4 through the shunt of the shunt grille 3, which helps to ensure the uniform and full utilization of the surface material of the HEPA filter element 4. Subsequently, the polluted gas will pass through the HEPA filter element 4 and the activated carbon filter element 5 in sequence and be discharged from the exhaust end at the rear to complete the purification.

[0046] Example 2, referring to Figure 4 and Figures 6-8 This embodiment is optimized on the basis of Embodiment 1. Specifically: An air purification auxiliary strengthening structure is provided on the sealing hatch cover 16. The air purification auxiliary strengthening structure includes a reciprocating cleaning component, a reciprocating lighting component, and a linkage drive;

[0047] Furthermore, the reciprocating cleaning component includes a chute 1 opened at the bottom of the sealing hatch cover 16, a reciprocating lead screw 17 rotatably installed in the chute 1, a reciprocating slider 18 fitted on the reciprocating lead screw 17, and a cleaning brush 19 fixedly connected to the outer wall of the bottom of the reciprocating slider 18.

[0048] Furthermore, the reciprocating lighting component includes a chute 2 opened at the bottom of the sealing hatch cover 16, a reciprocating lead screw 20 rotatably installed in the chute 2, a reciprocating slider 21 fitted on the reciprocating lead screw 20, and a UV lamp 22 fixedly installed on the outer wall of the bottom of the reciprocating slider 21. The outer wall of the reciprocating slider 21 is slidably connected to the inner wall of the chute 2, and the UV lamp 22 is located in the front area of the activated carbon filter element 5;

[0049] Further, the linkage drive includes a protective cover 23 fixedly connected to the side wall of the sealed bin cover 16, a drive motor 24 fixedly installed on the side wall of the protective cover 23, a double-groove pulley 25 fixedly sleeved on the output shaft of the drive motor 24, and two single-groove pulleys 26 fixedly sleeved on one ends of the first reciprocating lead screw 17 and the second reciprocating lead screw 20 in sequence. The output shaft of the drive motor 24 penetrates through the protective cover 23, and the double-groove pulley 25 is drivingly connected to the two single-groove pulleys 26 through two drive belts in sequence;

[0050] The working principle of this embodiment is as follows: First, the drive motor 24 drives the double-groove pulley 25 to rotate. Subsequently, under the driving effect of the two drive belts, the two single-groove pulleys 26 will drive the first reciprocating lead screw 17 and the lead screw 20 to rotate synchronously. In this way, the linkage effect of the two can be achieved by using the same drive source, effectively improving the utilization rate of the drive motor 24;

[0051] Secondly, the rotation of the first reciprocating lead screw 17 drives the first reciprocating slider 18 to reciprocate. Further, the first reciprocating slider 18 will drive the cleaning brush 19 to reciprocate on the surface of the HEPA filter element 4, facilitating the effective cleaning of the particulate impurities accumulated on the surface of the HEPA filter element 4, effectively reducing the blockage probability of the HEPA filter element 4, and thus being beneficial to improving the filtration efficiency of the HEPA filter element 4;

[0052] Finally, the rotation of the second reciprocating lead screw 20 drives the second reciprocating slider 21 to reciprocate. Further, the second reciprocating slider 21 will drive the UV lamp 22 to reciprocate, and the light source emitted by the UV lamp 22 is evenly irradiated on the front-end area of the activated carbon filter element 5. Thus, through the integration of the activated carbon filter element 5 and UV photocatalytic oxidation, volatile organic compounds in the polluted gas can be effectively removed, facilitating the effective enhancement of the air purification quality.

[0053] Example 3, referring to Figure 1 、 Figure 3 and Figure 8 This embodiment is optimized on the basis of Example 1. Specifically, the filter material replacement warning structure includes a sensor assembly 27 installed inside the exhaust end of the purification bin 2, and a single-chip microcomputer 28 and a warning device 29 fixedly installed on the outer wall of the top of the sealed bin cover 16 in sequence;

[0054] Further, the sensor assembly 27 is a multi-parameter air quality sensor for real-time monitoring of exhaust gas parameters. Both the sensor assembly 27 and the warning device 29 are electrically connected to the single-chip microcomputer 28. Then, when the sensor assembly 27 detects that the purified tail gas fails to meet the standard, at this time, a signal will be transmitted to the single-chip microcomputer 28, and the single-chip microcomputer 28 controls the warning device 29 to perform a warning operation to prompt the staff that the filter material inside needs to be replaced. In this way, it has the function of warning and reminding of filter material replacement, which helps to improve the timeliness of filter material replacement inside the air purification mechanism;

[0055] Specifically, a heat energy recovery structure includes a heat conduction sheet 30 fixedly embedded on the other side of the purification chamber 2, a thermoelectric converter 31 fixedly installed on the outer wall of the other side of the purification chamber 2, and a storage battery 32 fixedly installed on the thermoelectric converter 31.

[0056] Furthermore, the storage battery 32 is electrically connected to the charging interface end of the thermoelectric converter 31. Then, the heat energy in the polluted gas is absorbed by the heat conduction sheet 30 and transferred to the thermoelectric converter 31 for thermoelectric exchange. The thermoelectric converter 31 converts the heat energy into electrical energy and charges it into the storage battery 32 for storage. In this way, heat energy recovery and utilization can be achieved.

[0057] Example 4, referring to Figures 1-2 and Figure 9 , this embodiment is an optimization based on Embodiment 1. Specifically, the clamping rod structure includes a connecting frame 33 fixedly connected to the side wall of the purification chamber 2, two fitting blocks welded to the side wall of the connecting frame 33 in sequence, two sliding grooves opened on the connecting frame 33 in sequence, two locking screws 34 rotatably installed in the two sliding grooves in sequence, two movable blocks 35 screwed to the two locking screws 34 in sequence, two clamping blocks 36 fixedly arranged on the side walls of the two movable blocks 35 in sequence, and two knobs 37 fixedly connected to the outer walls of one ends of the two locking screws 34 in sequence.

[0058] Furthermore, the outer walls of the two movable blocks 35 are respectively slidably connected to the inner walls of the two sliding grooves, which is convenient for ensuring the stability of the linear movement of the two clamping blocks 36. The opposite sides of the two fitting blocks and the two clamping blocks 36 are both C-shaped notch structures, which is convenient for ensuring close fitting with the rod body 1 of the painting robotic arm during the clamping process.

[0059] The working principle of this embodiment: By fitting the two fitting blocks to the rod body 1 of the painting robotic arm, and then rotating the two locking screws 34 in sequence through the two knobs 37. Under the limitation of the sliding grooves, the two movable blocks 35 threadedly connected to the two locking screws 34 will drive the two clamping blocks 36 to move and clamp onto the rod body 1 of the painting robotic arm to achieve fixation. This is convenient for directly installing the entire air purification mechanism on the rod body 1 of the painting robotic arm, and can quickly solve the air pollution generated near the painting source, thereby helping to improve the working efficiency of the air purification work.
