Description

Technical Field

[0001] This utility model relates to the field of electronic technology, specifically to an exhaust filter element assembly. Background Technology

[0002] In the manufacturing and use of electronic components, exhaust filter elements play a crucial role. They are mainly used to filter and expel gaseous impurities generated inside the equipment, such as dust and harmful gases, to ensure the stable operation of electronic components and extend their service life. Currently, exhaust filter elements widely used in the market mostly adopt a multi-layer filter structure, achieving filtration through physical blocking. However, this traditional technical solution has the following significant drawbacks: although multi-layer filters can intercept most particulate matter, the filtration effect on small particles and some harmful gases is not ideal, making it difficult to meet the cleanliness requirements of high-precision electronic components. With the increase of usage time, the filter is prone to clogging and needs to be replaced regularly, increasing maintenance and time costs. Utility Model Content

[0003] The purpose of this utility model is to provide an exhaust filter element assembly to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: an exhaust filter element assembly, including a filter box, the interior of which is divided into upper and lower parts by a partition. Each part of the filter box is further divided into an exhaust chamber and an intake chamber. An exhaust filter element for removing gaseous impurities generated inside the exhaust device is provided between the exhaust chamber and the intake chamber. A self-cleaning component for cleaning the exhaust filter element is provided in the intake chamber.

[0004] Preferably, the exhaust filter assembly includes an exhaust fan installed inside the exhaust chamber, with a mounting hole at one end of the exhaust chamber, and a filter plate detachably connected between the exhaust fan and the mounting hole.

[0005] Preferably, the self-cleaning component includes an electric telescopic rod located inside the air intake chamber and mounted on a partition. A brush head is connected to the output end of the electric telescopic rod, the brush head being positioned corresponding to the filter plate. The brush head has bristles that contact the filter plate. A dust collection cabinet is located on one side of the filter plate within the lower air intake chamber. The interior of the dust collection cabinet communicates with the air intake chamber. A handle is connected to one side of the dust collection cabinet, and the dust collection cabinet is slidably and sealingly mounted on the filter box.

[0006] Preferably, both the filter plate and the filter plate 2 include a nanofiber layer, an activated carbon adsorption layer, and a ceramic layer. The nanofiber layer is used to intercept fine particulate matter, the activated carbon adsorption layer is used to adsorb harmful gases, and the ceramic layer has a plurality of filter holes to provide additional physical blocking and support.

[0007] Preferably, a flow monitor is installed between the filter plate and the exhaust fan, and a control board is installed on the outer wall of the filter box. The control board is connected to the exhaust fan, the air extraction fan, and the flow monitor.

[0008] Preferably, a protective net is installed at the end of the exhaust chamber away from the mounting hole.

[0009] Preferably, a ventilation mesh is installed in the middle of the partition, and dust collection holes are opened on the partition above the dust collection cabinet.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. By setting up a filter plate composed of multiple filter components to filter the gas discharged from the filter box layer by layer, the content of harmful substances and dust in the gas discharged from the filter box is reduced. Moreover, the filter plate, which combines multiple filtration functions, has a simple structure and, compared with the existing technology, has the effect of reducing the environmental harm of the emitted gas.

[0012] By setting a flow monitor, the gas flow rate through the filter plate can be monitored in real time. When the gas flow rate through the filter plate is lower than the set threshold, it indicates that the filter is blocked. At this time, the control board will control the electric telescopic rod to drive the brush head to clean the filter plate. The cleaned dust is concentrated in the dust collection cabinet, which prevents the filter plate from becoming blocked due to dust accumulation after long-term use, thus improving the filtration efficiency.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "connection" should be interpreted broadly. For example, they can be fixed connections, detachable connections, integral connections, mechanical connections, or electrical connections; they can be direct connections or indirect connections through an intermediate medium; and they can be internal connections between two components.

[0018] Example 1

[0019] like Figure 1-Figure 2 The exhaust filter element assembly shown includes a filter box 1, which is divided into upper and lower parts by a partition 20. Each part of the filter box 1 is divided into an exhaust chamber 8 and an air inlet chamber 10. The exhaust chamber 8 is equipped with an exhaust filter element for removing gaseous impurities generated inside the exhaust equipment. Protective nets 2 are installed at the ends of the exhaust chamber 8 away from the mounting hole 7 and the air inlet chamber 10 away from the dust collection cabinet 3. A ventilation net 11 is installed in the middle of the partition 20, which connects the two exhaust chambers 8. The two sets of exhaust chambers 8 and air inlet chambers 10 can improve the fault tolerance of the assembly during use, thereby ensuring the continuous operation of the assembly.

[0020] In this embodiment, the exhaust filtration assembly includes an exhaust fan 5, which is installed inside the exhaust chamber 8. One end of the exhaust chamber 8 has a mounting hole 7. A filter plate 9 is detachably connected between the exhaust fan 5 and the mounting hole 7. The filter box 1 is connected to the inside of the equipment through the mounting hole 7. When the exhaust fan 5 is turned on, harmful gases and dust generated inside the equipment can be sucked out. After being filtered by the filter plate 9, the gas can be discharged into the atmosphere, which can reduce the pollution of the environment caused by harmful gases, keep the inside of the device clean, and extend the service life of the equipment.

[0021] Example 2

[0022] The further improvement based on Example 1 is as follows: Figure 2-Figure 3The exhaust filter assembly shown includes a self-cleaning component in the intake chamber 10 for cleaning the exhaust filter assembly. The self-cleaning component includes an electric telescopic rod 6, which is located inside the intake chamber 10 and mounted on a partition 20. A brush head 12 is connected to the output end of the electric telescopic rod 6, and the brush head 12 is positioned corresponding to the filter plate 9. The brush head 12 has bristles that contact the filter plate 9. A dust collection cabinet 3 is located on one side of the filter plate 9 in the lower intake chamber 10. The interior of the dust collection cabinet 3 is connected to the intake chamber 1. A dust collection hole 19 is opened on the partition 20 above the dust collection cabinet 3. A handle 4 is connected to one side of the dust collection cabinet 3. The dust collection cabinet 3 is slidably and sealed on the filter box 1. When the brush head 12 is driven by the electric telescopic rod 6 for cleaning, the dust attached to one side of the filter plate 9 falls off and is collected in the upper dust collection cabinet 3 through the dust collection hole 19. For disposal, simply pull out the integrated cabinet 3 and empty it.

[0023] Both filter plate 9 and filter plate 12 include a nanofiber layer 13, an activated carbon adsorption layer 14, and a ceramic layer 15. The nanofiber layer 13 is used to intercept fine particulate matter, the activated carbon adsorption layer 14 is used to adsorb harmful gases, and the ceramic layer 15 has several filter holes 16 to provide additional physical barriers and support. Filter plate 9 and filter plate 12 are arranged in opposite directions. When the gas passes through filter plate 9 and filter plate 12, it passes through the nanofiber layer 13, the activated carbon adsorption layer 14, and the ceramic layer 15 in sequence. After layer-by-layer filtration, the filter components are combined together, resulting in a simple structure that is easy to install. This improves the filtration effect, allowing harmful gases and dust generated by electronic components to be filtered before being discharged, thus reducing the harm to the environment.

[0024] A flow monitor 17 is installed between the filter plate 9 and the exhaust fan 5. A control board 18 is installed on the outer wall of the filter box 1. The control board 18 is connected to both the exhaust fan 5 and the flow monitor 17. The flow monitor 17 can monitor the gas flow through the filter plate 9 in real time. When the gas flow is lower than the set threshold, it indicates that the filter plate 9 is blocked. At this time, the control board 18 will control the electric telescopic rod 6 to drive the brush head 12 to clean the filter plate 9. The cleaned dust is collected in the dust collection cabinet 3 to achieve automatic cleaning of the filter plate 9.

[0025] The process flow and working principle of this utility model are as follows: Electronic components generate harmful gases and dust during use. By starting the exhaust fan 5, the harmful gases and dust generated inside the equipment can be sucked out. The gas is filtered through layers of filter plates 9 before being discharged into the atmosphere, which can reduce the pollution of the environment caused by harmful gases, keep the inside of the device clean, and extend the service life of the equipment. The filter plate 9 is composed of multiple filter components, with a simple structure and easy disassembly. The flow monitor 17 can monitor the gas flow through the filter plate 9 in real time. When the gas flow through the filter plate 9 is lower than the set threshold, it indicates that the filter plate 9 is blocked. At this time, the control board 18 will control the electric telescopic rod 6 to drive the brush head 12 to clean the filter plate 9. The cleaned dust is collected in the dust collection cabinet 3, realizing the automatic cleaning of the filter plate 9. This avoids the filter plate 9 from becoming blocked by dust after long-term use, which would reduce the filtration effect and improve the filtration rate of the gas.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
