Description

Technical Field

[0001] This utility model relates to the field of Class 100 laminar flow hood technology, specifically to a Class 100 laminar flow hood with a noise reduction structure. Background Technology

[0002] A Class 100 laminar flow hood is an air purification unit that provides a local clean environment. The air is first pre-filtered through a pre-filter to remove large dust particles and other impurities. After pre-treatment, the air is then filtered a second time through a high-efficiency filter. Under the pressure provided by a centrifugal fan, the air meets the cleanliness requirements and finally forms a uniform flow layer, allowing the clean air to flow vertically in one direction, thereby ensuring that the Class 100 cleanliness level required by the process is achieved in the working area.

[0003] Currently, the use of Class 100 laminar flow hoods lacks auxiliary noise reduction mechanisms. Since the fan itself easily generates vibration and noise during operation, and after prolonged use, some components of the laminar flow hood, such as the housing and ductwork, may age, deform, or become damaged, leading to loose connections between components. This results in vibration and noise during operation, causing significant noise levels in the actual use of the Class 100 laminar flow hood. Therefore, this paper proposes a Class 100 laminar flow hood with a noise reduction structure to enhance its stability during operation through support and vibration damping. This makes it less susceptible to vibration and noise from the fan, thereby improving its performance. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a Class 100 laminar flow hood with a noise reduction structure, which improves the stability of the Class 100 laminar flow hood during operation, makes it less susceptible to vibration and noise caused by fan vibration, and thus improves the performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is a Class 100 laminar flow hood with a noise reduction structure, including a box, a vibration damping component and a positioning component. The vibration damping component is provided on the top of the box, and the positioning component is fixedly provided on the top of the box around the vibration damping component. The mounting component corresponding to the positioning component is provided on the top of the vibration damping component.

[0006] The vibration damping component includes a sleeve, and the housing is bolted to the sleeve. A rod is sleeved to the top of the sleeve, and a pad is bolted to the top of the rod. A spring is sleeved around the rod between the sleeve and the pad, and a compression spring is provided at the bottom of the rod inside the sleeve.

[0007] By adopting the above technical solutions, sleeves, rods, pads, springs, and compression springs can be added to increase the auxiliary noise reduction mechanism. By using support and shock absorption methods, the stability of the Class 100 laminar flow hood can be improved, making it less prone to vibration and noise. The structure is simple, the cost is low, and the use is more reasonable and reliable.

[0008] Specifically, the positioning component includes a support column, one side of which has a groove, and a positioning block is rotatably connected within the groove.

[0009] By adopting the above technical solutions, the support columns, grooves, and positioning blocks can enhance the rapid splicing and positioning process. By using plug-in, flipping, and limiting methods, the ease of disassembly and assembly of the box can be improved. The structure is simple, the cost is low, and the disassembly and assembly are more reasonable and flexible.

[0010] Specifically, both sides of the positioning block are connected to a rotating shaft by bolts, and the positioning block is rotatably connected to the groove through the rotating shaft. A coil spring is sleeved around the rotating shaft, and one end of the coil spring is connected to the rotating shaft by welding, while the other end of the coil spring is connected to the groove through a slot.

[0011] By adopting the above technical solution, the positioning block can be automatically flipped and limited by elastic deformation, while improving the convenience of box recycling and disassembly.

[0012] Specifically, the mounting assembly includes a support plate, the surface of which has an opening corresponding to the positioning assembly, and a mounting bracket is bolted to the top of the support plate.

[0013] By adopting the above technical solution, the support plate, opening and mounting bracket can be pre-installed and can be quickly disassembled and assembled with the positioning components.

[0014] Specifically, a pre-filter is bolted to the top of the housing, a fan is installed at the top of the housing with the fan's air inlet located inside the pre-filter, a high-efficiency purifier is bolted to the bottom of the fan inside the housing, a flow equalization membrane is installed at the bottom of the high-efficiency purifier, and a flow equalization plate is installed at the bottom of the housing.

[0015] By adopting the above technical solutions, the primary air purifier, fan, and high-efficiency air purifier can purify the air, while the flow equalization membrane and flow equalization plate can improve the uniformity of the airflow.

[0016] Specifically, the bottom of the fan is provided with a flow guide shroud at the outer periphery of the air outlet, the bottom of the flow guide shroud is provided with a flow divider groove, the flow divider groove is provided with an inclined groove, and the surface of the inner body of the box is provided with sound insulation cotton.

[0017] By adopting the above technical solutions, the flow guide, flow divider, and inclined groove can increase the auxiliary flow guiding and flow dividing mechanism, reduce the noise generated when the airflow flows rapidly, and the sound insulation cotton can increase the sound insulation structure and further improve the sound insulation effect.

[0018] The beneficial effects of this utility model are:

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To improve the stability of the Class 100 laminar flow hood during operation, making it less susceptible to vibration and noise from the fan, and thus improving its performance, such as... Figure 1-3 As shown, the Class 100 laminar flow hood with noise reduction structure of this utility model includes a housing 1, a vibration damping component 3 and a positioning component 4. The vibration damping component 3 is provided on the top of the housing 1, and the positioning component 4 is fixedly provided on the top of the housing 1 around the vibration damping component 3. The mounting component 2 corresponding to the positioning component 4 is provided on the top of the vibration damping component 3.

[0031] The vibration damping component 3 includes a sleeve 301, and the housing 1 is connected to the sleeve 301 by bolts. A sleeve rod 302 is sleeved and connected to the top of the sleeve 301. A pad 303 is bolted to the top of the sleeve rod 302. A spring 304 is sleeved on the periphery of the sleeve rod 302 between the sleeve 301 and the pad 303. A compression spring 305 is provided inside the sleeve 301 at the bottom of the sleeve rod 302.

[0032] In use, the auxiliary noise reduction mechanism can be added through the sleeve 301, sleeve rod 302, pad 303, spring 304 and compression spring 305. By using support and shock absorption, the stability of the Class 100 laminar flow hood can be improved, and it is less likely to vibrate or cause noise. The structure is simple, the cost is low, and the use is more reasonable and reliable.

[0033] To improve ease of assembly and disassembly, for example, such as Figure 1 , Figure 3 As shown, the present invention also includes a positioning component 4, which includes a support column 401. A groove 402 is provided on one side of the support column 401, and a positioning block 403 is rotatably connected in the groove 402.

[0034] In use, the support column 401, groove 402 and positioning block 403 can increase the quick splicing and positioning process. By using plug-in, flipping and limiting methods, the ease of disassembly and assembly of the box 1 is improved. The structure is simple, the cost is low, and the disassembly and assembly are more reasonable and flexible.

[0035] For example, such as Figure 3 As shown, the present invention also includes a rotating shaft 404 bolted to both sides of the positioning block 403, and the positioning block 403 is rotatably connected to the groove 402 through the rotating shaft 404. A coil spring 405 is sleeved around the rotating shaft 404, and one end of the coil spring 405 is welded to the rotating shaft 404, and the other end of the coil spring 405 is connected to the groove 402 through a slot.

[0036] In use, the rotating shaft 404 and the coil spring 405 can use elastic deformation to drive the positioning block 403 to automatically perform a flipping and limiting action, while improving the convenience of recycling and disassembling the box 1.

[0037] For example, such as Figure 4 As shown, the present invention also includes a support plate 201, the surface of which has an opening 202 corresponding to the positioning component 4, and a mounting bracket 203 is bolted to the top of the support plate 201.

[0038] During use, the support plate 201, opening 202 and mounting bracket 203 can be used for pre-installation, and the positioning component 4 can be used for quick assembly and disassembly.

[0039] For example, such as Figure 5 As shown, the present invention also includes a primary air purifier 5 bolted to the top of the housing 1, a fan 6 installed at the top inside the housing 1 with the air inlet of the fan 6 located inside the primary air purifier 5, a high-efficiency air purifier 9 bolted to the bottom of the fan 6 inside the housing 1, a flow equalization membrane 10 installed at the bottom of the high-efficiency air purifier 9, and a flow equalization plate 11 installed at the bottom inside the housing 1.

[0040] During use, the air is purified by the primary air purifier 5, the fan 6 and the high-efficiency air purifier 9, and the uniformity of the airflow is improved by the flow equalization membrane 10 and the flow equalization plate 11.

[0041] For example, such as Figure 5 , Figure 6 As shown, the present invention also includes a flow guide shroud 8 located on the periphery of the air outlet at the bottom of the fan 6, a flow divider 7 located at the bottom of the flow guide shroud 8, an inclined groove 701 being formed in the flow divider 7, and sound insulation cotton 101 being provided on the surface inside the housing 1.

[0042] In use, the flow guide shroud 8, the flow divider 7 and the inclined groove 701 can increase the auxiliary flow guiding and diversion mechanism, reduce the noise generated when the airflow flows rapidly, and the sound insulation cotton 101 can increase the sound insulation structure and further improve the sound insulation effect.

[0043] In use, the operator first uses the mounting bracket 203 to bolt the support plate 201, then passes the support column 401 at the top of the box 1 through the corresponding opening 202. Under the elastic force of the coil spring 405, the positioning block 403 of the rotating shaft 404 flips outward, so that the positioning block 403 is stuck on the top of the support plate 201. The installation operation is more convenient and labor-saving. Moreover, when it needs to be replaced later, the box 1 only needs to be lifted slightly and the positioning block 403 pushed back into the groove 402 to complete the separation of the support column 401 from the support plate 201. The structure is simple, the operation is convenient, and the use is more flexible and reliable.

[0044] Moreover, in actual operation, the vibration generated by the fan 6 can be reduced and suppressed by the vibration pushing point 303, sleeve rod 302 and compression spring 305, thereby achieving the effect of auxiliary noise reduction. At the same time, the airflow entering the housing 1 through the primary purifier 5 and the fan 6 can be diverted under the guidance of the inclined groove 701 of the diversion groove 7, thereby reducing the vibration and noise generated by the airflow pressure, making the use more stable and reliable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
