[0027] like Figure 2 , 3As shown, the sliding mechanism 4 includes a detachable buckle frame 41, a pair of upper guide rods 42 and a pair of lower guide rods 43. The two upper guide rods 42 are respectively vertically arranged on the front support rods 31 close to the two sides of the air purification box 1, and the two lower guide rods 43 are respectively vertically arranged at the lower parts of the two front support rods 31. The adjacent upper guide rods 42 and lower guide rods 43 are staggered. The inner sides of the two upper guide rods 42 are respectively provided with upper slide grooves 421 with openings facing each other, and the inner sides of the two lower guide rods 43 are respectively provided with lower slide grooves 431 with openings facing each other. The sliding window 24 includes a window body 241 and a slide rod 242. The slide rod 242 is fixedly connected to the window body At the bottom of 241, both ends of the slide bar 242 are horizontally embedded in the corresponding lower slide groove 431, and the slide bar 242 can move up and down in the lower slide groove 431. The corresponding upper slide grooves 421 are respectively embedded on both sides of the window body 241, and the window body 241 can slide up and down in the upper slide groove 421. The detachable buckle frame 41 includes two buckle strips 411 opposite to the corresponding front support rod 31, and the two buckle strips 411 are fixedly connected to a panel 412 opposite to the air purification box 1.

[0028] The adjacent upper guide rods 42 and lower guide rods 43 are staggered, so that when the slide rod 242 moves to the top of the lower guide rod 43, the bottom of the upper guide rod 42 can limit the slide rod 242 to prevent the slide rod 242 from detaching from the lower guide rod 43, thereby ensuring the safety of the movement of the sliding window 24.
[0029] like Figure 2 , 3 As shown in , 5, the counterweight mechanism 6 includes a pulley block 61 and a counterweight stone 62. The pulley block 61 includes a pulley frame 611 and a pulley 612 rotatably connected to the pulley frame 611. The counterweight stone 62 is in the shape of an elongated strip. A chamber 311 is provided in the center of the front support rod 31 along the length direction. One end of the rope 5 is fixedly connected to one end of the slide rod 242, and the other end of the rope 5 is fixedly connected to the counterweight stone 62 through the pulley 612. The pulley frame 611 is clamped at the top of the chamber 311 of the corresponding front support rod 31.

[0030] like Figure 4As shown, the cross-section of the buckle strip 411 is U-shaped, and the buckle strip 411 includes a front plate 4111. The front plate 4111 has outer plates 4112 and inner plates 4113 extending backward and perpendicular thereto on both sides thereof. The width of the inner plate 4113 is smaller than that of the outer plate 4112, so that a slideway for the sliding rod 242 to pass through is formed between the inner plate 4113 and the corresponding front support rod 31.
[0031] During specific implementation, the weight of the counterweight 62 and the sliding window 24 can be adjusted to be the same. Since the counterweight 62 and the sliding window 24 are connected by the rope 5, when the sliding window 24 is pushed upward or downward, the rope 5 on the counterweight 62 drives the counterweight 62 to move downward or upward in the chamber 311 on the front support rod 31 through the pulley set 61, and the external force on the sliding window 24 is stopped. Then, under the action of the counterweight 62, the sliding window 24 can immediately stop moving and remain stationary, and the sliding rod 242 can hover at any position of the lower guide rod 43, so that the up and down adjustment of the sliding window 24 is convenient and quick.

[0036] Before using the workbench, first start the fan 12, which presses the purified air into the workbench 21. The air in the workbench 21 is discharged to the outside through the ventilation holes 71 on the ventilation plate 7. After the fan 12 works for a period of time, the clean air fills the working room, which can ensure that the air in the working room 2 meets the working requirements.
[0037] An ultraviolet sterilization lamp (not shown) is arranged in the studio 2.
[0038] In order to facilitate the movement of the workbench and the stability of the work, a cross bar 33 is fixedly connected between the bottoms of the adjacent front support rods 31 and the rear support rods 32, and the bottoms of both ends of the cross bar 33 are respectively fixedly connected to universal rollers 8; the bottoms of the front support rods 31 and the rear support rods 32 are threadedly connected to the support legs 9.
[0039] When the workbench needs to be moved, the legs 9 can be rotated upward and off the ground, and the universal rollers 8 can be in contact with the ground, so that the workbench can be conveniently moved by the universal rollers 8. When the workbench is moved to a specified position, the legs 9 can be rotated downward to make the universal rollers 8 suspended in the air, and the legs 9 can be against the ground to support the workbench, which can stabilize the workbench and ensure the normal use of the workbench.
[0040] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model.
