Description

Technical Field

[0001] This utility model relates to the field of fume hoods, specifically a fume hood with UV photocatalysis and activated carbon filtration. Background Technology

[0002] In scientific research, experimentation, and industrial production, the pursuit of safety and precision has never ceased. Fume hoods have emerged as an indispensable key piece of equipment. Early experimental environments were rudimentary, with harmful gases and dust spreading freely, seriously threatening the health of laboratory personnel and often interfering with experimental results. With technological advancements and increased safety awareness, fume hoods have gradually taken center stage. Utilizing a unique airflow design, they rapidly capture and expel various toxic and harmful gases, vapors, and dust generated during experiments, effectively preventing their spread within the laboratory. Today, fume hoods are widely used in laboratories in chemistry, biology, medicine, and many other fields. From basic research to product development, from university laboratories to corporate R&D centers, they silently safeguard every experimental operation. However, as the environmental requirements for scientific research and production increase, existing fume hoods are gradually becoming insufficient to meet people's needs, necessitating the design of a more effective fume hood to satisfy these requirements.

[0003] An existing type of fume hood with UV photocatalysis and activated carbon filtration typically consists of a fume hood body. Inside the fume hood body, one side is equipped with an air guide plate, a filter plate, and a UV lamp assembly. An activated carbon plate is also installed on one side of the UV lamp assembly. When the ventilation fan inside the fume hood is turned on, the UV lamp assembly and activated carbon plate can enhance the air purification effect of the fume hood.

[0004] However, for existing fume hoods with UV photocatalysis and activated carbon filtration, when the fume hood is used for a long time, a lot of dust will accumulate on the filter plate inside the fume hood. When the filter plate is pulled out of the existing fume hood, the filter plate will shake, causing the dust on the filter plate to fall into the fume hood, thus affecting the normal use of the fume hood. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a fume hood with UV photocatalysis and activated carbon filtration to solve the technical problem mentioned in the background art of poor performance of existing fume hoods with UV photocatalysis and activated carbon filtration.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fume hood with UV photocatalysis and activated carbon filtration, comprising a fume hood body, a side opening on one side of the fume hood body, a movable door panel movably installed on one side of the fume hood body, an air guide plate at one end inside the fume hood body, a UV lamp and an activated carbon plate fixedly installed on one side inside the fume hood body, an installation plate fixedly installed inside the fume hood body, an installation groove at the top of the installation plate, a first pulley movably installed in the installation groove, an inner cavity at one end of the installation groove, a spring fixedly installed at the bottom of the inner cavity, a slider at one end of the spring, a second pulley movably installed between the sliders, a limit block movably installed inside the installation groove, a filter plate fixedly installed between the limit blocks, and a dust-proof plate on one side of the filter plate.

[0007] By adopting the above technical solution, the problem of poor performance of existing fume hoods with UV photocatalysis and activated carbon filtration mentioned in the background technology is solved. Two sets of mounting plates are staggered inside the fume hood body, each with a mounting groove. Multiple sets of first pulleys are movably installed between the mounting grooves. When the limiting block is fitted inside the mounting groove, the movably installed first pulleys allow the limiting block to slide more smoothly, preventing vibration of the limiting block and the filter plate between it, thus preventing dust adhering to the filter plate from falling off. Simultaneously, due to the staggered arrangement of the two sets of mounting plates, the filter plate can be tilted inside the fume hood body. When the filter plate and the limiting block vibrate, dust can slide along the tilted surface of the filter plate and fall onto the limiting block, preventing dust from falling into the fume hood body and affecting its normal operation. Furthermore, a dust-proof plate is also tilted on one side of the filter plate, which can block falling dust, further enhancing the filter plate's performance.

[0008] The present invention is further configured such that the movable door panel is movably installed on one side of the side opening, and the cross-sectional area of ​​the movable door panel is larger than the cross-sectional area of ​​the side opening.

[0009] Preferably, by movably installing the movable door panel on one side of the side opening, the cross-sectional area of ​​the movable door panel is larger than the cross-sectional area of ​​the side opening, so that the movable door panel can cover the side opening and prevent external media from entering the interior of the fume hood body, thereby affecting the normal use of the fume hood body.

[0010] The present invention is further configured such that the height of the mounting plate is greater than the height between the side opening and the bottom of the fume hood body, and one end of the mounting plate is located on one side of the side opening.

[0011] Preferably, by setting the height of the mounting plate to be greater than the height between the side opening and the bottom of the fume hood body, and setting one end of the mounting plate on one side of the side opening, the limiting block can be fitted into the mounting groove opened on the top of the mounting plate, thereby enabling the filter plate to achieve the desired effect.

[0012] The present invention is further configured such that the first pulley is provided in multiple sets, and the side of the first pulley is at the same level as the side of the side opening.

[0013] Preferably, by setting multiple sets of first pulleys, and the side of the first pulley is at the same level as the side of the side opening, the limiting block can slide smoothly in the mounting groove, avoiding the filter plate and the limiting block from shaking, so that the dust on the filter plate falls downward.

[0014] The present invention is further configured such that the side of the second pulley is higher than the side of the first pulley and the side opening, and the surface of the second pulley is coated with a rubber coating.

[0015] Preferably, by setting the side of the second pulley higher than the side of the first pulley and the side opening, when the limiting block is installed inside the mounting groove, the second pulley, through the spring, can exert a squeezing effect on the limiting block, preventing the limiting block from sliding freely in the mounting groove and thus affecting the performance of the filter plate. The surface of the second pulley is coated with a rubber coating, which can enhance the friction between the second pulley and the limiting block, thereby achieving the limiting effect of the second pulley.

[0016] The present invention is further configured such that there are two sets of mounting plates, and the two sets of mounting plates are staggered.

[0017] Preferably, by providing two sets of mounting plates, and staggering the two sets of mounting plates, the filter plate can be tilted between the two sets of mounting plates, thereby improving the dustproof effect of the filter plate.

[0018] The present invention is further configured such that both the filter plate and the dust-proof plate are inclined, and the height of the dust-proof plate is greater than the thickness of the filter plate.

[0019] Preferably, by tilting both the filter plate and the dust-proof plate, with the height of the dust-proof plate being greater than the thickness of the filter plate, when the filter plate and the limiting block shake, the downward sliding dust can be blocked, preventing dust from falling into the interior of the fume hood body and thus affecting the performance of the fume hood body.

[0020] The present invention is further configured such that the two ends of the limiting block are provided with inclined angles, and the thickness of the limiting block is the same as the width of the mounting groove.

[0021] Preferably, by setting inclined angles at both ends of the limiting block, when the limiting block contacts the second pulley, it can better press the second pulley downward, which facilitates the installation of the filter plate and the limiting block and makes the device more practical. The thickness of the limiting block is the same as the width of the mounting groove, so that the limiting block can be stably installed inside the mounting groove, avoiding the filter plate and the limiting block from shaking during use, thereby affecting the use effect of the filter plate and the limiting block.

[0022] In summary, the present invention has the following main advantages:

[0023] This utility model, by comprising a fume hood body, side opening, movable door panel, air guide plate, UV lamp, activated carbon plate, mounting plate, mounting groove, first pulley, inner cavity, spring, slider, second pulley, filter plate, limiting block, and dustproof plate, solves the problem of poor performance of existing fume hoods with UV photocatalysis and activated carbon filtration mentioned in the background art. It solves this problem by having two sets of mounting plates staggered inside the fume hood body, each with a mounting groove. Multiple sets of first pulleys are movably installed between the mounting grooves. When the limiting block is fitted inside the mounting groove, the movably installed first pulleys allow the limiting block to slide more smoothly. The design is smooth to prevent vibration of the limiting blocks and the filter plates between them, thus preventing dust adhering to the filter plates from falling off. Simultaneously, the staggered arrangement of the two sets of mounting plates allows the filter plates to be tilted inside the fume hood body. When the filter plates and limiting blocks vibrate, dust can slide along the tilted surface of the filter plates and fall onto the limiting blocks, preventing dust from falling into the fume hood body and affecting its normal operation. Furthermore, a dust-proof plate is tilted on one side of the filter plate, which further blocks falling dust, enhancing the filter plate's effectiveness.

[0024] 2. This utility model features an installation plate with an installation groove at its top and an inner cavity at one end. A spring is fixedly installed at the bottom of the inner cavity, and a slider is connected to one end of the spring. A second pulley is movably installed between the sliders. The side of the second pulley is higher than that of the first pulley, and the surface of the second pulley is coated with a rubber coating. When the filter plate and the limiting block are fitted into the installation groove, the second pulley, through the spring, applies a squeezing force to the limiting block, thus limiting its movement and preventing the filter plate and the limiting block from sliding freely within the installation groove, which would affect the filter plate's performance. Additionally, the limiting block has inclined angles at both ends at its bottom. When the limiting block contacts the second pulley, it better presses the second pulley downwards, facilitating the installation of the filter plate and the limiting block and making the device more practical.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Please see Figures 1-9The system includes a fume hood body 1, a side opening 2 on one side of the fume hood body 1, a movable door panel 3 on one side of the fume hood body 1, an air guide plate 4 inside the fume hood body 1, a UV lamp 5 and an activated carbon plate 6 fixedly installed inside the fume hood body 1, an installation plate 7 fixedly installed inside the fume hood body 1, an installation groove 71 on the top of the installation plate 7, a first pulley 8 movably installed in the installation groove 71, an inner cavity 9 at one end of the installation groove 71, a spring 10 fixedly installed at the bottom of the inner cavity 9, a slider 11 at one end of the spring 10, a second pulley 12 movably installed between the sliders 11, a limit block 14 movably installed inside the installation groove 71, a filter plate 13 fixedly installed between the limit blocks 14, and a dustproof plate 15 on one side of the filter plate 13.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 4 The movable door panel 3 is movably installed on one side of the side opening 2. The cross-sectional area of ​​the movable door panel 3 is larger than that of the side opening 2. By movably installing the movable door panel 3 on one side of the side opening 2, the cross-sectional area of ​​the movable door panel 3 is larger than that of the side opening 2, so that the movable door panel 3 can cover the side opening 2, preventing external media from entering the interior of the fume hood body 1, thereby affecting the normal use of the fume hood body 1.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 and Figure 7 The height of the mounting plate 7 is greater than the height between the side opening 2 and the bottom of the fume hood body 1. One end of the mounting plate 7 is set on one side of the side opening 2. By setting the height of the mounting plate 7 to be greater than the height between the side opening 2 and the bottom of the fume hood body 1, and setting one end of the mounting plate 7 on one side of the side opening 2, the limiting block 14 can be fitted into the mounting groove 71 opened on the top of the mounting plate 7, so that the filter plate 13 can achieve the desired effect.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 and Figure 7 Multiple sets of first pulleys 8 are provided. The side of the first pulley 8 is at the same level as the side of the side opening 2. By providing multiple sets of first pulleys 8 and ensuring that the side of the first pulley 8 is at the same level as the side of the side opening 2, the limiting block 14 can slide smoothly in the mounting groove 71, preventing the filter plate 13 from shaking and causing the dust on the filter plate 13 to fall downwards.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 7The side of the second pulley 12 is higher than the side of the first pulley 8 and the side opening 2. The surface of the second pulley 12 is coated with a rubber coating. By setting the side of the second pulley 12 higher than the side of the first pulley 8 and the side opening 2, when the limiting block 14 is installed inside the mounting groove 71, the second pulley 12 can exert a squeezing effect on the limiting block 14 through the spring 10, preventing the limiting block 14 from sliding freely in the mounting groove 71, thereby affecting the use effect of the filter plate 13. The rubber coating on the surface of the second pulley 12 can enhance the friction between the second pulley 12 and the limiting block 14, thereby achieving the limiting effect of the second pulley 12.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The mounting plate 7 is provided in two sets, and the two sets of mounting plates 7 are staggered. By providing two sets of mounting plates 7 and staggering them, the filter plate 13 can be tilted between the two sets of mounting plates 7, which improves the dustproof effect of the filter plate 13.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figure 8 Both the filter plate 13 and the dust-proof plate 15 are inclined. The height of the dust-proof plate 15 is greater than the thickness of the filter plate 13. By inclining both the filter plate 13 and the dust-proof plate 15, and making the height of the dust-proof plate 15 greater than the thickness of the filter plate 13, when the filter plate 13 and the limiting block 14 shake, they can block the downward sliding dust and prevent the dust from falling into the interior of the fume hood body 1, thereby affecting the use effect of the fume hood body 1.

[0045] For details regarding the above embodiments, please refer to [link / reference]. Figure 9 The limiting block 14 has inclined angles at both ends. The thickness of the limiting block 14 is the same as the width of the mounting groove 71. By setting inclined angles at both ends of the limiting block 14, when the limiting block 14 contacts the second pulley 12, it can better press the second pulley 12 downward, which facilitates the installation of the filter plate 13 and the limiting block 14 and makes the device more practical. The thickness of the limiting block 14 is the same as the width of the mounting groove 71, so that the limiting block 14 can be stably installed inside the mounting groove 71, avoiding the filter plate 13 and the limiting block 14 from shaking during use, thereby affecting the use effect of the filter plate 13 and the limiting block 14.

[0046] In practical operation, when the fume hood body 1 has been used for a long time and a lot of dust has accumulated on the filter plate 13, requiring replacement, the movable door panel 3, which is movably installed on one side of the fume hood body 1, is opened. Then, the filter plate 13 and the limiting block 14 are pulled out from the mounting groove 71. The mounting groove 71 is located at the top of the mounting plate 7, which is fixedly installed inside the fume hood body 1. Multiple sets of first pulleys 8 are movably installed inside the mounting groove 71. The sides of the first pulleys 8 contact the limiting block 14. When the limiting block 14 slides inside the mounting groove 71, the first pulleys 8 enable the limiting block 14 to slide more smoothly. This design prevents the limiting block 14 and the filter plate 13 between the limiting blocks 14 from shaking, thus avoiding dust falling into the fume hood body 1. Furthermore, because the two sets of mounting plates 7 are relatively staggered, the filter plate 13 can be tilted inside the fume hood body 1. When the filter plate 13 shakes, the dust accumulated on its surface will slide down the tilted surface and fall onto the limiting block 14 at the bottom of the filter plate 13, preventing dust from falling into the fume hood body 1 and affecting its normal operation. A dust-proof plate 15 is also tilted on one side of the filter plate 13 to block falling dust. The filter plate 13 further reduces dust diffusion, allowing it to achieve better performance. An inner cavity 9 is also provided at one end of the mounting groove 71. A spring 10 is fixedly installed at the bottom of the inner cavity 9, and a slider 11 is connected to one end of the spring 10. A second pulley 12 is movably mounted between the sliders 11. The side of the second pulley 12 is higher than the side of the first pulley 8, and the surface of the second pulley 12 is coated with a rubber coating. When the filter plate 13 and the limiting block 14 are fitted into the mounting groove 71, the second pulley 12, through the spring 10, can exert a compressive force on the limiting block 14, thereby limiting its movement. The positioning function prevents the filter plate 13 and the limiting block 14 from sliding freely inside the mounting groove 71, thus affecting the performance of the filter plate 13. At the same time, the two ends of the bottom of the limiting block 14 are also provided with tilt angles. When the limiting block 14 contacts the second pulley 12, it can better press the second pulley 12 downward, which facilitates the installation of the filter plate 13 and the limiting block 14 and makes the device more practical. UV lamp 5 and activated carbon plate 6 are also fixedly installed inside the fume hood body 1. When the device is in use, the UV lamp 5 and activated carbon plate 6 can better purify the air, so that the device can achieve better performance.
