At the same time, a smoke exhaust pipe is set up in the workshop, and dust removal equipment is set up outside the workshop. The operation room is connected to the smoke exhaust pipe, and the smoke exhaust pipe sucks the welding smoke in the operation room into the dust removal equipment, and the smoke is treated by the dust removal equipment before being discharged in compliance with the standards.

When the wind direction switching plate is vertical, the second fresh air hole coincides with the first fresh air hole. The wind direction switching channel also includes a third fresh air hole opened on the other side of the wind direction switching plate. The number of the first fresh air holes is the same as that of the second fresh air holes, and both are several. The third fresh air hole is a slot, and a shutter is installed in the third fresh air hole. When the wind direction switching plate is vertical, the fresh air from the second fresh air hole passes through the shutter and enters the operating room. A flexible tube is connected between the free end of the wind direction switching plate and the first fresh air holes in the bottom row.

Then, the wind direction switching channel is horizontally discharged into the operating room, so that the purpose of ventilation in the operating room is achieved. Although the operating room is small, the quality of the welding environment is improved after the fresh air is discharged. The injection of fresh air also speeds up the air flow speed in the operating room. The welding smoke generated in the operating room during the welding process can quickly enter the smoke exhaust pipe, which speeds up the efficiency of welding smoke cleaning. When the welding work is completed and the worker leaves the operation room, he rotates the wind direction switching plate downward to switch it to horizontal. At this time, the wind direction switching channel on the wind direction switching plate is longitudinally connected to the first fresh air hole on the fresh air plate. The fresh air system continues to provide fresh air to the fresh air hood. After being collected by the fresh air hood, the fresh air enters the fresh air plate longitudinally through the first fresh air hole, and then is longitudinally discharged into the wind direction switching channel through the first fresh air hole, and then longitudinally discharged into the operation room through the wind direction switching channel. At this time, since the wind direction switching plate is relatively horizontal, the wind direction switching channel is changed to longitudinal air intake, which is equivalent to the wind direction switching channel blowing longitudinally relative to the top direction of the operation room. The welding smoke remaining in the operation room after welding is quickly blown into the smoke exhaust pipe, further improving the welding smoke cleaning efficiency.

[0022] The above and other embodiments and advantages of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.
[0023] In one embodiment, Figures 1-8 As shown:
[0024] The present embodiment provides an air purification device for a dust-free workshop, comprising an operating room 1, a fresh air system 2, an air outlet switching mechanism 3 and a wind direction conversion component 4; the fresh air system 2 comprises a fresh air cover 21 connected to the side of the operating room 1 and a fresh air plate 22 arranged on the operating room 1, the fresh air plate 22 is provided with a first fresh air hole 23 from top to bottom, the first fresh air hole 23 is horizontally drawn toward the operating room 1, the air outlet switching mechanism 3 comprises a wind direction switching plate 31 that rotates relatively on the inner side of the fresh air plate 22, and a wind direction switching plate 31 is provided with a wind direction switching plate 31. The wind direction switching channel 32, the wind direction conversion component 4 includes a driving rod mechanism 41 arranged between the wind direction switching channel 32 and the operating room 1, and also includes a boost combination 42 arranged between the fresh air plate 22 and the wind direction switching plate 31; when the wind direction switching plate 31 is rotated to vertical, the wind direction switching channel 32 is transformed into a channel that is connected to the first fresh air hole 23 and takes in air horizontally; when the wind direction switching plate 31 is rotated to horizontal, the wind direction switching channel 32 is transformed into a longitudinal air intake, and the boost combination 42 is triggered to increase the longitudinal exhaust intensity of the wind direction switching channel 32.
[0025] In actual use, dust removal equipment such as desulfurization towers and bag dust collectors will be installed outside the workshop, and Figure 1 、 Figure 2 As shown, a smoke exhaust pipe is provided, and the air outlet of the smoke exhaust pipe is connected to the dust removal device. The welding smoke generated in the operating room 1 enters the smoke exhaust pipe and is discharged into the dust removal device through the smoke exhaust pipe. After being purified by the dust removal device, it meets the discharge standards. In this embodiment, when the worker is welding in the operating room 1, the wind direction switching plate 31 is rotated upwards to turn the wind direction switching plate 31 to the left. Figure 3 、 Figure 5 The shape shown is erected on the inner side of the fresh air plate 22. At this time, the wind direction switching channel 32 on the wind direction switching plate 31 is horizontally connected to the first fresh air hole 23 on the fresh air plate 22. The fresh air system 2 provides fresh air to the fresh air hood 21. The fresh air is collected by the fresh air hood 21 and enters the fresh air plate 22 horizontally through the first fresh air hole 23. It is then horizontally discharged into the wind direction switching channel 32 through the first fresh air hole 23, and then horizontally discharged into the operating room 1 through the wind direction switching channel 32, so that the purpose of ventilation is achieved in the operating room 1. Although the operating room 1 is small, the welding environment quality is improved after the fresh air is discharged. The worker's back is facing the fresh air direction switching plate 31, and the horizontally discharged fresh air acts on the back of the human body, relieving fatigue and improving comfort. At the same time, the injection of fresh air also speeds up the air flow speed in the operating room 1. The welding smoke generated in the operating room 1 during the welding process can quickly enter the smoke exhaust pipe, which speeds up the efficiency of welding smoke cleaning.
[0026] When the welding work is completed and the worker leaves the operating room 1, he rotates the wind direction switch plate 31 downwards so that the wind direction switch plate 31 is pressed. Figure 7 The shape shown is basically horizontal. At this time, the wind direction switching channel 32 on the wind direction switching plate 31 is longitudinally connected to the first fresh air hole 23 on the fresh air plate 22. The fresh air system 2 continues to provide fresh air to the fresh air hood 21. The fresh air is collected by the fresh air hood 21 and enters the fresh air plate 22 longitudinally through the first fresh air hole 23. Then, it is longitudinally discharged into the wind direction switching channel 32 through the first fresh air hole 23, and then longitudinally (upward air intake) is discharged into the operating room 1 through the wind direction switching channel 32. At this time, since the wind direction switching plate 31 is in a relatively horizontal position, the wind direction switching channel 32 is converted to longitudinal air intake, which is equivalent to the wind direction switching channel 32 blowing longitudinally relative to the top direction of the operating room 1. The welding smoke remaining in the operating room 1 after welding is quickly blown into the smoke exhaust pipe, further improving the welding smoke cleaning efficiency.
[0027] Continuing from the above, in this embodiment, a boost combination 42 is set between the fresh air plate 22 and the wind direction switching plate 31. When the wind direction switching plate 31 rotates horizontally to face the longitudinal air intake in the top direction of the operating room 1, the boost combination 42 is also triggered to increase the exhaust intensity of the wind direction switching channel 32 in the longitudinal direction, thereby further improving the welding smoke cleaning efficiency.
[0028] In another embodiment, Figure 3 、 Figure 6 as well as Figure 7 As shown, the wind direction switching plate 31 is a cavity structure. For example, if the wind direction switching plate 31 is rectangular, a rectangular cavity is provided inside it. The wind direction switching channel 32 includes a second fresh air hole 321 opened on one side of the wind direction switching plate 31. When the wind direction switching plate 31 is vertical, the second fresh air hole 321 coincides with the first fresh air hole 23. At this time, when the first fresh air hole 23 takes in air, the fresh air enters the second fresh air hole 321 from the first fresh air hole 23, and enters the cavity of the wind direction switching plate 31 from the second fresh air hole 321 for collection; in addition, the wind direction switching channel 32 also includes a third fresh air hole 322 opened on the other side of the wind direction switching plate 31. After the fresh air is collected in the cavity, it is blown into the operating room 1 through the third fresh air hole 322 on the other side. The number of the first fresh air holes 23 is the same as that of the second fresh air holes 321, and both are several, which increases the air intake speed. The third fresh air hole 322 is a rectangular slot, and a shutter 323 is installed in the third fresh air hole 322. When the wind direction switching plate 31 is vertical, the fresh air from the second fresh air hole 321 passes through the shutter 323 and enters the operating room 1. A flexible tube 312 is connected between the free end of the wind direction switching plate 31 and the first fresh air hole 23 in the bottom row.
[0029] In this embodiment, it is well known that the shutters 323 are controllable, that is, when the shutters 323 are closed, it is equivalent to closing the third fresh air hole 322. When the wind direction switching plate 31 is erected on the inner side of the fresh air plate 22, the shutters 323 are opened. At this time, the third fresh air hole 322, the second fresh air hole 321, and the first fresh air hole 23 are horizontally connected. The fresh air enters the second fresh air hole 321 through the first fresh air hole 23, enters the third fresh air hole 322 through the second fresh air hole 321, and then enters the operating room 1 through the third fresh air hole 322, realizing horizontal air intake. When the worker is welding in the operating room 1, the horizontally discharged fresh air acts on the back of the human body, relieves fatigue, and improves comfort. On the contrary, when the shutters 323 are closed, the third fresh air hole 322 is closed, and then the wind direction switching plate 31 is pressed Figure 7 As shown, it rotates downward to a horizontal position. At this time, only the second fresh air hole 321 exhausts air upward (vertically). At the same time, the flexible tube 312 sends fresh air into the cavity of the wind direction switching plate 31. Since the third fresh air hole 322 is closed, the fresh air will not leak downward through the third fresh air hole 322 at this time, but will be concentratedly sprayed upward through the second fresh air hole 321, thereby increasing the blowing intensity and accelerating the exhaust speed of welding smoke.
[0030] In another embodiment, Figures 5 to 8As shown, the interior of the fresh air plate 22 is provided with a vertical cavity 2201 up and down, and the booster combination 42 includes a control panel 421 arranged in the cavity 2201, and the top of the control panel 421 is provided with an adjustment rod 422 that extends to the outside of the top of the fresh air plate 22, and the top of the adjustment rod 422 is provided with a sloped seat 423, and the free end of the wind direction switching plate 31 is provided with a driving part 311 that is in a rolling relationship with the slope on the sloped seat 423, and a fourth fresh air hole 424 is provided on the control panel 421. When the wind direction switching plate 31 is rotated to vertical, the sloped seat 423 is rolled by the driving part 311, and the control panel 421 is pushed down by the sloped seat 423 and the adjusting rod 422, so that the fourth fresh air hole 424 on the control panel 421 is horizontally connected with the first fresh air hole 23 on the fresh air plate 22. A spring seat is provided at the bottom of the clamping cavity 2201 (the spring seat is a prior art and only needs to be purchased and installed), and the bottom end of the control board 421 is elastically supported on the top end of the spring seat.
[0031] When the wind direction switching plate 31 rotates to stand upright on the inner side of the fresh air plate 22, the driving part 311 at the top of the wind direction switching plate 31 will crush the inclined surface of the inclined seat 423, forcing the inclined seat 423 to push the adjustment rod 422 down, and the adjustment rod 422 pushes the control plate 421 down. At this time, the spring seat is compressed and shortened, and the first fresh air hole 23 on the control plate 421 and the spring seat push the control plate 421 to rise and reset. At this time, the fourth fresh air hole 424 on the control plate 421 is horizontally connected to the first fresh air hole 23 on the fresh air plate 22, thereby realizing horizontal air intake. When the wind direction switching plate 31 rotates to the horizontal position, the driving part 311 at the top disengages from the inclined seat 423, the rolling pressure on the inclined seat 423 disappears, and the spring seat pushes the control plate 421 to rise and reset. At this time, the non-hole area on the control plate 421 is intercepted on the first fresh air holes 23. Except for the first fresh air holes 23 in the bottom row for ventilation, all other first fresh air holes 23 are closed and no air is taken in. The fresh air enters the fresh air cover 21 and is then discharged from the fresh air cover 21 to the fresh air plate 22. It is also discharged into the wind direction switching plate 31 only through the flexible tube 312 on the first fresh air holes 23 in the bottom row. Inside the exchange plate 31, the remaining first fresh air holes 23 are prevented from exhausting at this time. When the wind direction switching plate 31 is horizontal, its exhaust direction is controlled to be upward, and only the medium gas volume will discharge the welding smoke remaining in the operating room 1 upward. The setting of the boost combination 42 can control the exhaust intensity of the fresh air plate 22, and can also control the exhaust direction of the fresh air plate 22 according to the position change of the wind direction switching plate 31. For example, when the wind direction switching plate 31 is horizontal, it is limited to blowing air vertically upward only, avoiding the obstruction of the horizontal air intake to the vertical blowing, so that the air volume after the position of the wind direction switching plate 31 is changed is more reasonable.
[0032] In another embodiment, the drive rod mechanism 41 includes a small connecting rod 411 hinged at the end of each shutter 323, and a drive rod 412 that hinges all the small connecting rods 411 together, one end of the drive rod 412 exceeds the damping shaft 24, and the drive rod mechanism 41 also includes an electric cylinder 413 installed on the cavity wall of the operating room 1. When the wind direction switching plate 31 rotates to horizontal, the end of the drive rod 412 exceeds the damping shaft 24 and presses on the action rod of the electric cylinder 413, and the shutter 323 is automatically closed after being pushed in the opposite direction by the action rod of the electric cylinder 413. A button 101 is provided between the door of the operating room 1 and the inner wall of the operating room 1. When the door is closed, the button is triggered to control the electric cylinder 413 to automatically start.
[0033] When a worker leaves the operating room 1 and rotates the wind direction switching plate 31 downward to a horizontal position, the wind direction switching plate 31 causes the blinds 323 to rotate downward, which in turn causes the small connecting rod 411 to rotate downward. This in turn causes the driving rod 412 to rotate downward, and the extended end of the driving rod 412 is aligned with the actuating rod of the electric cylinder 413. The actuating rod of the electric cylinder 413 extends and strikes the driving rod 412, pushing the driving rod 412 in a straight line. The driving rod 412 drives all the small connecting rods 411 to rotate, and all the small connecting rods 411 close all the blinds 323. Therefore, in this embodiment, when a worker leaves the operating room 1, they only need to rotate the wind direction switching plate 31 downward to a horizontal position to automatically close the blinds 323, making operation easier. The control button 101 for the electric cylinder 413 operating room 1 can be located on the door of the operating room 1, automatically activating the electric cylinder 413 when the door is closed.
[0034] It should be further explained that the inner side of the fresh air plate 22 is a rubber plate. When the wind direction switching plate 31 is rotated to vertical, the side with the second fresh air hole 321 is tightly attached to the inner side of the rubber plate to form a relative sealing effect, ensuring that the second fresh air hole 321 and the first fresh air hole 23 overlap.
[0035] It should be further explained that a hinge groove 313 is provided at the bottom end of the wind direction switching plate 31, and a damping shaft 24 is provided at the bottom of the inner side surface of the fresh air plate 22. The hinge groove 313 is connected to the damping shaft 24. The damping shaft 24 can be understood as the wind direction switching plate 31 being able to stop and position when it rotates to a certain angle. For example, a ratchet mechanism is provided at one end of the shaft to achieve this function. The ratchet or damping shaft control method is a prior art and will not be repeated in the present invention.
[0036] It should be further explained that the operating room 1 is located in the workshop, and the fresh air system 2 also includes a fan arranged outside the workshop. The air outlet of the fan is connected to a fresh air duct, and the air outlet of the fresh air duct is connected to the fresh air hood 21.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described based on their actual installation and actual use, as well as the customary orientations of those skilled in the art.
