AI Technical Summary
In the existing fume hood design, the internal space is unadjustable, resulting in the idle space being underutilized. At the same time, excessive space will reduce negative pressure, increase the risk of harmful gas leakage, and thus increase energy consumption and environmental noise.
A side panel adjustable fume hood is designed. By setting movable side panels and upper and lower driving devices on the cabinet body, the height of the top panel and the angle of the movable side panel are adjusted, thereby adjusting the size of the space inside the cabinet body, increasing negative pressure, and preventing harmful gas leakage.
Under the same air exhaust, the internal space of the fume hood is adjusted to increase the negative pressure to effectively prevent harmful gases from overflowing; under the same negative pressure, the air exhaust volume is reduced, and energy consumption and noise are reduced.

Technical Field
[0001] The utility model relates to the technical field of fume hoods, in particular to a fume hood with adjustable side panels. Background Art
[0002] In the current fume hood design, there is usually a large internal space to meet the personalized needs of various users. However, in the actual operation process, the internal space is not adjustable, and a large amount of free space is not fully utilized. At the same time, too much space will also lead to a decrease in the negative pressure generated in the fume hood. This reduction in negative pressure will increase the risk of internal harmful gas leakage. In order to ensure that sufficient negative pressure is maintained in the cabinet to prevent the leakage of harmful gases, the fume hood needs to have a higher exhaust volume, which will lead to problems such as energy consumption and environmental noise.

When the up and down driving device starts to work, it drives the entire top panel to move up and down, and the movable side panel can rotate a certain angle around the hinge between the movable side panel and the side of the cabinet body. The larger the angle between the movable side panel and the side of the cabinet body, the smaller the internal space of the fume hood will be, thereby increasing the negative pressure in the cabinet and preventing the leakage of harmful gases.
[0006] Furthermore, the top plate is provided with a slideway in the length direction of the cabinet, a pulley is installed on the slideway, and a connector is installed on the pulley; the connector is hinged to the top of the movable side plate, so that the top of the movable side plate can rotate relative to the top plate and can also move linearly along the slideway through the pulley. The connector can be a hook, a hinge, etc.
[0007] Furthermore, the top plate is provided with two parallel slideways in the length direction of the cabinet body, so that the movable side plate is more stable.
[0008] Furthermore, the bottom of the movable side panel is connected to the side of the cabinet through a long row of hinges, so that the movable side panel can rotate around the long row of hinges.
[0009] Furthermore, a support frame is detachably connected to the top plate, and the support frame is connected to the upper and lower driving devices.
[0010] Furthermore, the cabinet is provided with a slide rail, and the top plate and / or the support frame are provided with a slider used in conjunction with the slide rail. The slider is sleeved on the slide rail and moves up and down along the slide rail.

[0012] Furthermore, two movable side panels are provided, namely a left movable side panel and a right movable side panel, and the up and down movement of the top panel can drive the top of the left movable side panel and the top of the right movable side panel to move toward each other.
[0013] Furthermore, the up and down driving device is connected to the supporting frame via a connecting bracket.
[0014] Furthermore, the up and down driving device is a driving device such as an electric push rod, an oil cylinder or a pneumatic cylinder.
[0015] Technical effects of the utility model:
[0016] Compared with the prior art, the utility model provides a fume hood with adjustable side panels, in which movable side panels are arranged inside the cabinet. The size of the space inside the cabinet can be adjusted by adjusting the height of the top plate, so that the space inside the cabinet can be fully utilized. Under the condition of the same exhaust volume, the smaller the internal space, the higher the negative pressure, which is more conducive to preventing the overflow of harmful gases; under the condition of the same negative pressure, the smaller the internal space, the smaller the exhaust volume, so that the energy consumption is lower and the noise is lower.

[0024] A top plate 8 is provided on the top of the cabinet 1, and the top plate 8 is slidably connected to the inner wall of the cabinet 1 up and down. Specifically, a slide rail 9 is provided on the cabinet 1, and preferably, a slide rail 9 is provided at four right angles formed by the front and rear sides and the left and right sides of the cabinet 1. A support frame 6 is detachably connected to the top plate 8, and the support frame 6 is connected to the up and down driving device 3 through a connecting bracket 7. The up and down driving device 3 is an electric push rod fixed to the top of the cabinet 1. A slider 4 used in conjunction with the slide rail 9 is provided on the support frame 6, and the slider 4 is sleeved on the slide rail 9 and moves up and down along the slide rail 9.
[0025] A movable side panel 2 is provided below the top panel 8. Two movable side panels 2 are provided, namely a left movable side panel 21 and a right movable side panel 22. The bottom of the left movable side panel 21 is connected to the left side of the cabinet 1 through a long row of hinges 11, so that the left movable side panel 21 can rotate relative to the left side of the cabinet 1 around the long row of hinges 11; the bottom of the right movable side panel 22 is connected to the right side of the cabinet 1 through a long row of hinges 11, so that the right movable side panel 22 can rotate relative to the right side of the cabinet 1 around the long row of hinges 11. The tops of the left movable side panel 21 and the right movable side panel 22 are both connected to the top panel 8, and the top panel 8 can move up and down to drive the tops of the left movable side panel 21 and the right movable side panel 22 to move toward each other. Specifically, the top plate 8 is provided with two parallel slideways 5 in the length direction of the cabinet body 1, and a pulley 10 with a hook is installed on the slideway 5; the pulley 10 with a hook is connected to the top of the left movable side plate 21 and the top of the right movable side plate 22, so that the top of the left movable side plate 21 and the top of the right movable side plate 22 can rotate relative to the top plate 8, and can also move towards each other along the slideway 5 in the length direction of the cabinet body 1 through the pulley 10.
[0026] Working principle: When the utility model is in use, the operator can adjust the size of the internal space of the cabinet 1 according to the actual use situation. When adjusting the internal space, the electric push rod is powered on to work, pushing the top plate 8 to move up and down along the linear slide rail 9; the pulley 10 with a hook is connected to the movable side plate 2, and the pulley 10 with a hook can make a linear motion in the slideway 5, thereby driving the movable side plate 2 to rotate at a certain angle relative to the side plate of the cabinet 1 around the long hinge 11. The larger the angle between the movable side plate 2 and the side of the cabinet 1, the smaller the internal space of the fume hood will be, thereby realizing the size adjustment of the internal space of the fume hood.
