[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides: an operating room air purification device, such as Figure 1-5 As shown, it includes a purification box body 1, mounting plates 3 are fixedly installed on both sides of the purification box body 1, air inlet hole plates 11 and air outlet hole plates are respectively arranged inside the two groups of mounting plates 3, and door panel assemblies for shielding the air inlet hole plates 11 and the air outlet hole plates are arranged on the side of the two groups of mounting plates 3 away from the purification box body 1, and driving assemblies 9 for driving the door panel assemblies to open and close are arranged on the side of the two groups of mounting plates 3 away from the purification box body 1, and a filter screen 13 is fixedly installed inside the purification box body 1, a dust collecting box 2 is arranged at the bottom of the purification box body 1 and below the filter screen 13, and a dust scraping assembly for cleaning dust from the filter screen 13 is arranged on the side of the filter screen 13.

[0028] The door panel assembly includes a first rotating door 5, a first traction door 6, a second rotating door 7 and a second traction door 8. A limiting plate 15 is fixedly installed on the side of the mounting plate 3 away from the purification box body 1. The first rotating door 5 and the second traction door 8 are both rotatably arranged on the lower surface of the limiting plate 15. The first traction door 6 is rotatably connected to the first rotating door 5, and the second rotating door 7 is rotatably connected to the second traction door 8. When the first traction door 6 moves toward the first rotating door 5, the first traction door 6 will fold and rotate in a circle with the contact point of the first rotating door 5 as the first rotating door, and at the same time push the first rotating door 5 to rotate on the lower surface of the limiting plate 15. Similarly, the second rotating door 7 and the second traction door 8 can be folded and opened, and the air purification device can be used normally.

[0029] The first traction door 6 and the second rotating door 7 are located between the first rotating door 5 and the second traction door 8, and the first traction door 6 and the second rotating door 7 are in contact. When the door panel assembly is closed, the first rotating door 5 and the first traction door 6 are in contact, the first traction door 6 and the second rotating door 7 are in contact, and the second rotating door 7 and the second traction door 8 are in contact, thereby ensuring that dust in the outside air will not enter the interior of the purification box body 1 through the gaps.

[0030] The driving assembly 9 includes a first rotating wheel 17, a belt 18, a second rotating wheel 19 and a motor 20. The first rotating wheel 17 and the second rotating wheel 19 are both rotatably arranged on the side of the mounting plate 3 away from the purification box body 1. The belt 18 is rotatably sleeved on the outer arc surface of the first rotating wheel 17 and the second rotating wheel 19. The motor 20 is bolted to the side of the mounting plate 3 away from the purification box body 1, and the second rotating wheel 19 is keyed to the output end of the motor 20. The motor 20 is started to drive the second rotating wheel 19 to rotate, and the second rotating wheel 19 drives the first rotating wheel 17 to rotate through the belt 18 on the outer arc surface.

[0031] The driving assembly 9 also includes a traction plate 22, a clamping block 23, a connecting block 24 and a rotating support column 25. The traction plate 22, the clamping block 23, the connecting block 24 and the rotating support column 25 are each provided with two groups. The two groups of traction plates 22 are respectively rotatably arranged on the upper surfaces of the first traction door 6 and the second rotating door 7. The two groups of clamping blocks 23 are fixedly installed on one side of the traction plate 22 close to the purification box body 1. When the traction plate 22 moves, the first traction door 6 and the second rotating door 7 will rotate and fold simultaneously with the movement of the traction plate 22.

[0032] One group of connecting blocks 24 is fixedly mounted on the upper surface of the corresponding traction plate 22, and the connecting blocks 24 are in contact with the lower half of the belt 18. Another group of connecting blocks 24 is fixedly mounted on the upper surface of the corresponding traction plate 22 through a group of heightening plates, and another group of connecting blocks 24 is in contact with the upper half of the belt 18. The upper half and the lower half of the belt 18 move in opposite directions, and the two groups of connecting blocks 24 are in contact with the upper half and the lower half respectively, thereby ensuring that the first traction door 6 and the second rotating door 7 move relatively close or relatively far away.

[0033] The sides of the two groups of connecting blocks 24 are provided with through holes 26 corresponding to the belts 18, and the two groups of rotating anti-pillars 25 are rotatably set on the upper surfaces of the corresponding connecting blocks 24, and the two groups of rotating anti-pillars 25 are threadedly penetrated through the corresponding connecting blocks 24 and contacted with the belts 18. By rotating the rotating anti-pillars 25, the connecting blocks 24 are fixedly connected to the belts 18 inside the through holes 26, and when the belt 18 moves, it will drive the connecting blocks 24 to move, and then drive the first traction door 6 or the second rotating door 7 to rotate and move through the traction plate 22.

[0034] The upper and lower surfaces of the limit plate 15 are provided with movable grooves 16 corresponding to the clamping blocks 23. A support plate 4 is fixedly installed on the side of the mounting plate 3 away from the purification box body 1, and the door panel assembly is in contact with the upper surface of the support plate 4. Side baffles 21 are fixedly installed on the upper surface of the support plate 4 and on both sides of the door panel assembly. The traction plate 22 is clamped into the movable groove 16 through the clamping blocks 23, thereby ensuring that the traction plate 22 can only move in a straight line, and the first rotating door 5, the first traction door 6, the second rotating door 7 and the second traction door 8 are all in contact with the support plate 4, and the two sets of side baffles 21 block the two sides, thereby preventing dust from entering the purification box body 1 through the gap.

[0035] The dust scraping assembly includes a lifting column 10 and a scraper 14. The scraper 14 is fitted on both sides of the filter 13. The lifting column 10 passes through the top surface of the purification box body 1 and is fixedly connected to the scraper 14. The lifting column 10 drives the scraper 14 to move up and down to scrape both sides of the filter 13, thereby scraping off the dust.

[0036] A through hole corresponding to the dust collecting box 2 is opened on the side of the purification box body 1, and a pull ring 12 is fixedly connected to one side of the dust collecting box 2 located inside the through hole. The dust scraped by the scraper 14 will enter the dust collecting box 2. The dust collecting box 2 can be pulled out of the through hole by pulling the pull ring 12, thereby quickly removing the dust inside the dust collecting box 2.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
