[0024] 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.

[0025] See also Figure 1-5 The utility model provides a technical solution: an injection molded PP air-supplementing fume hood, comprising a fume hood 1 and a guard plate 2, air-supplementing ducts 7 are installed on the left and right sides of the fume hood 1, and an exhaust duct 8 is arranged on the back of the fume hood 1, a touch-screen integrated machine 4 is fixedly installed on one side of the fume hood 1, and an operating table 5 is slidably connected to the middle of the fume hood 1, a fixing block 12 is installed on one side wall of the fume hood 1, and an adjusting component 6 is clamped at the bottom of the operating table 5, a slider 13 is threadedly sleeved in the middle of the adjusting component 6, a pull rod 11 is hinged in the middle of the slider 13, and a guard plate 2 3 is sleeved inside the guard plate 2, and the guard plate 2 3 is sleeved with one end of the adjusting component 6.

[0026] The adjusting component 6 is clamped on the bottom of the operating table 5, and the middle thread of the adjusting component 6 is sleeved with a slider 13, so that the adjusting component 6 is rotated, and the slider 13 moves along the external thread of the adjusting component 6. The slider 13 moves and drives the pull rod 11 to rotate at the hinge. At this time, the pull rod 11 is deformed, and the pull rod 11 forms a supporting force upward and pushes the operating table 5 to rise. When the operating table 5 descends, the adjusting component 6 is rotated in the opposite direction to move the slider 13 along the direction of the adjusting component 6. The movement of the slider 13 causes the pull rod 11 to rotate along the hinge of the slider 13, and the pull rod 11 forms a supporting force downward, pushing the operating table 5 to descend, thereby avoiding the problem of the operator's work being restricted and the long-term use causing great fatigue to the operator's body.

[0027] See also Figure 4 , Figure 5 An electric heating plate 9 is installed at the bottom of the inner wall of the fume hood 1, and an air supply port 10 is fixedly installed on the inner wall of the fume hood 1 and located on the top of the electric heating plate 9. The touch-control integrated machine 4 is connected to the electric heating plate 9 through a wire, and an activated carbon adsorption filter is provided on the inner side of the air supply port 10.

[0028] The air inside the fume hood 1 is extracted through the exhaust pipe 8, and the two air supply pipes 7 draw the outdoor air into the fume hood 1 for heating through the electric heating plate 9. The touch-screen all-in-one machine 4 controls its temperature. The air heated to a suitable temperature can enter the room through the air supply port 10, and the activated carbon adsorption filter can adsorb and filter the gas generated during the experiment to prevent harmful gases from affecting the health of the experimenters.

[0029] See also Figure 3 , Figure 5 The guard plate 2 3 is sleeved with the inside of the guard plate 1 2, and a circular hole is opened on the front and near the top of the guard plate 2 3, and the adjustment component 6 is sleeved inside the circular hole. The slider 13 is threadedly sleeved with the outside of the adjustment component 6, and the middle of the slider 13 is hinged with one end of the pull rod 11, and the other end of the pull rod 11 is hinged with the fixed block 12.

[0030] The control slider 13 is moved through the adjustment component 6. Since the middle part of the slider 13 is hinged to one end of the pull rod 11, and the other end of the pull rod 11 is hinged to the fixed block 12, the slider 13 moves and drives the pull rod 11 to rotate at the hinge. The pull rod 11 is deformed, and the pull rod 11 forms a supporting force upward, and pushes the operating table 5 and the adjustment component 6 to rise, thereby adjusting the height of the operating table 5.

[0031] See also Figure 4 , Figure 5 The adjustment component 6 includes a screw rod 601, which is fixedly and movably installed at the bottom of the operating table 5, and the slider 13 is threadedly sleeved on the outside of the screw rod 601. A handle 602 is fixedly installed at one end of the screw rod 601, and the middle part of the handle 602 is sleeved on the inside of the guard plate 2 3. The adjustment component 6 also includes two handles 602, which are fixedly installed on the left and right sides of the bottom of the operating table 5, and the left and right ends of the slider 13 are slidably connected to the outside of the two handles 602.

[0032] The slider 13 can be moved by adjusting the screw rod 601 in the assembly 6. Since the slider 13 is threadedly sleeved on the outside of the screw rod 601 and a handle 602 is fixedly installed on one end of the screw rod 601, the handle 602 and the screw rod 601 are rotated, and the slider 13 slides along the screw rod 601 and the limit rod 603, so that the slider 13 moves and the main pull rod 11 rotates at the hinge, causing the pull rod 11 to deform, and the pull rod 11 forms a supporting force upward, pushing the operating table 5 and the adjustment assembly 6 to rise, thereby adjusting the height of the operating table 5.

[0033] During operation, the adjusting component 6 is clamped on the bottom of the operating table 5, and the middle thread of the adjusting component 6 is sleeved with a slider 13, so that the adjusting component 6 is rotated, and the slider 13 moves along the external thread of the adjusting component 6, and the slider 13 moves and drives the pull rod 11 to rotate at the hinge. At this time, the pull rod 11 is deformed, and the pull rod 11 forms a supporting force upward and pushes the operating table 5 to rise. When the operating table 5 descends, the adjusting component 6 is rotated in the opposite direction to make the slider 13 move along the direction of the adjusting component 6. The movement of the slider 13 causes the pull rod 11 to rotate along the hinge of the slider 13, and the pull rod 11 forms a supporting force downward, pushing the operating table 5 to descend, thereby avoiding the operator's work being restricted and the problem of great fatigue to the operator's body caused by long-term use.

[0034] The air inside the fume hood 1 is extracted through the exhaust pipe 8, and the two air supply pipes 7 draw the outdoor air into the fume hood 1 for heating through the electric heating plate 9. The touch-screen all-in-one machine 4 controls its temperature. The air heated to a suitable temperature can enter the room through the air supply port 10, and the activated carbon adsorption filter can adsorb and filter the gas generated during the experiment to prevent harmful gases from affecting the health of the experimenters.

[0035] The control slider 13 is moved through the adjustment component 6. Since the middle part of the slider 13 is hinged to one end of the pull rod 11, and the other end of the pull rod 11 is hinged to the fixed block 12, the slider 13 moves and drives the pull rod 11 to rotate at the hinge. The pull rod 11 is deformed, and the pull rod 11 forms a supporting force upward, and pushes the operating table 5 and the adjustment component 6 to rise, thereby adjusting the height of the operating table 5.

[0036] The slider 13 can be moved by adjusting the screw rod 601 in the assembly 6. Since the slider 13 is threadedly sleeved on the outside of the screw rod 601 and a handle 602 is fixedly installed on one end of the screw rod 601, the handle 602 and the screw rod 601 are rotated, and the slider 13 slides along the screw rod 601 and the limit rod 603, so that the slider 13 moves and the main pull rod 11 rotates at the hinge, causing the pull rod 11 to deform, and the pull rod 11 forms a supporting force upward, pushing the operating table 5 and the adjustment assembly 6 to rise, thereby adjusting the height of the operating table 5.

[0037] In summary, the device rotates the adjustment component 6, causing the slider 13 to move along the external thread of the adjustment component 6. At the same time, the slider 13 moves and drives the pull rod 11 to rotate at the hinge. At this time, the pull rod 11 is deformed, and the pull rod 11 forms a supporting force, thereby adjusting the height of the operating table 5, thereby avoiding the operator's work being restricted and causing great fatigue to the operator's body due to long-term use.
