Description

Technical Field

[0001] This utility model belongs to the field of filter mounting bracket technology, specifically relating to an FFU embedded filter mounting bracket. Background Technology

[0002] An embedded filter mounting bracket is a mounting device specifically designed for embedded filters in FFU (Fan Filter Unit) fan filter units. It is usually customized according to the internal space of the FFU and the size and shape of the filter. It is installed in an embedded manner inside the FFU equipment to fix and support the filter, ensuring that the filter maintains the accurate position and orientation during FFU operation. It fits tightly with other FFU components to form a good sealing structure, achieving efficient air filtration function. At the same time, it facilitates the installation, disassembly and replacement of the filter to meet the air purification requirements in different environments.

[0003] However, traditional embedded bracket installation relies on complex processes such as screw tightening and clip fixing, which not only consumes a lot of time for calibration and positioning, but also requires a high level of technical proficiency from the installers, making it difficult to achieve efficient and rapid installation. In addition, its structural design lacks flexibility and cannot be easily adjusted to adapt to the internal space of FFUs of different sizes and specifications. It can only be customized according to specific specifications, which not only increases production costs such as mold development and material procurement, but also extends the delivery cycle. When facing diverse needs, it exposes obvious limitations and economic shortcomings.

[0004] To address the aforementioned issues, this application proposes an FFU embedded filter mounting bracket. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides an FFU embedded filter mounting bracket, which improves the ease of installation and applicability of the embedded bracket.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an FFU embedded filter mounting bracket, including a support frame, a filter is snapped into the inside of the support frame, a rubber sleeve is fixedly connected to the outer surface of the support frame, an air pump, a controller, and an electronic valve are respectively arranged above the support frame, the output end of the air pump is fixedly connected to the input end of the electronic valve, a connecting pipe is fixedly connected to the outer surface of the rubber sleeve, a pressure sensor is arranged above the connecting pipe, the sensing end of the pressure sensor passes through the connecting pipe and extends into the inside of the connecting pipe, and the end of the connecting pipe near the air pump is fixedly connected to the output end of the electronic valve.

[0007] As a preferred embodiment of this utility model, the support frame is internally fitted with two sets of fixing pins, and the outer surface of each fixing pin is fixedly connected to the inner wall of the filter.

[0008] As a preferred embodiment of this utility model, a protective shell is fixedly connected to the upper surface of the support frame, and the inner wall of the protective shell is in contact with the outer surface of the connecting pipe.

[0009] As a preferred embodiment of this utility model, the upper surface of the protective shell is movably hinged with an opening and closing door, and the upper surface of the opening and closing door is fixedly connected with an assist plate.

[0010] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to the bottom surface of the controller, and the bottom surface of the fixing plate is fixedly connected to the upper surface of the support frame.

[0011] As a preferred embodiment of this utility model, the bottom surface of the air pump is fixedly connected to a connecting seat, and the bottom surface of the connecting seat is fixedly connected to the upper surface of the support frame.

[0012] As a preferred embodiment of this utility model, a fixing frame is fixedly connected to the outer surface of the electronic valve, and the bottom surface of the fixing frame is fixedly connected to the upper surface of the support frame.

[0013] As a preferred embodiment of this utility model, a sealing ring is fixedly connected to the outer surface of the pressure sensor, and the bottom surface of the sealing ring is fixedly connected to the outer surface of the connecting pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a controller, an air pump, a rubber sleeve, a connecting pipe, and a pressure sensor, a convenient installation method is achieved. During installation, simply operate the air pump to inflate the rubber sleeve. After the rubber sleeve expands, it can fit tightly against the inside of the FFU, firmly fixing the entire mounting bracket. Unlike traditional installation methods, there is no need for complicated screw tightening and clip fixing operations, which greatly shortens the installation time and reduces the installation difficulty. At the same time, the rubber sleeve can adaptively adjust according to the actual size of the internal space of the FFU during the inflation process. This makes the mounting bracket highly adaptable, eliminating the need to customize brackets for different specifications of FFUs, thereby effectively reducing production costs and production cycle.

[0023] Please see Figure 1-4 The present invention provides the following technical solution: an FFU embedded filter mounting bracket, including a support frame 1, a filter 3 is snapped into the inside of the support frame 1, a rubber sleeve 2 is fixedly connected to the outer surface of the support frame 1, an air pump 8, a controller 10 and an electronic valve 12 are respectively arranged above the support frame 1, the output end of the air pump 8 is fixedly connected to the input end of the electronic valve 12, a connecting pipe 13 is fixedly connected to the outer surface of the rubber sleeve 2, a pressure sensor 16 is arranged above the connecting pipe 13, the sensing end of the pressure sensor 16 passes through the connecting pipe 13 and extends into the inside of the connecting pipe 13, and the end of the connecting pipe 13 near the air pump 8 is fixedly connected to the output end of the electronic valve 12;

[0024] In this embodiment, filter 3 mainly filters particulate matter in the air through principles such as interception, inertial collision, diffusion, and electrostatic attraction. The filter material is mostly ultra-fine glass fiber paper or polypropylene fiber, etc., and the structure has a partition type. It also has high filtration efficiency for microorganisms such as bacteria and viruses, and is a key component for achieving a high-cleanliness air environment.

[0025] Specifically, the support frame 1 has two sets of fixing pins 4 inside, and the outer surface of each fixing pin 4 is fixedly connected to the inner wall of the filter 3. In this embodiment, the support frame 1 and the filter 3 can be fixed by the fixing pins 4, so that the filter 3 can be fixed inside the support frame 1 for use.

[0026] Specifically, a protective shell 5 is fixedly connected to the upper surface of the support frame 1. The inner wall of the protective shell 5 is in contact with the outer surface of the connecting pipe 13. In this embodiment, the air pump 8, controller 10, pressure sensor 16 and electronic valve 12 can be housed within the protective shell 5, thereby improving the stability of the equipment.

[0027] Specifically, the upper surface of the protective shell 5 is movably hinged with an opening and closing door 6, and an assist plate 7 is fixedly connected to the upper surface of the opening and closing door 6. In this embodiment, the protective shell 5 can be opened or closed through the opening and closing door 6, and the assist plate 7 can be used to easily open or close the protective shell 5. The opening of the opening and closing door 6 allows heat dissipation inside the protective shell 5.

[0028] Specifically, a fixing plate 9 is fixedly connected to the bottom surface of the controller 10. The bottom surface of the fixing plate 9 is fixedly connected to the upper surface of the support frame 1. In this embodiment, the controller 10 can be fixedly used through the fixing plate 9. At the same time, the controller 10 is a single-chip microcomputer control device with powerful computing capabilities and rich interface resources. It can run complex operating systems and control software, and it can realize functions such as data storage, analysis and remote monitoring.

[0029] Specifically, the bottom surface of the air pump 8 is fixedly connected to the connecting seat 11, and the bottom surface of the connecting seat 11 is fixedly connected to the upper surface of the support frame 1. In this embodiment, the air pump 8 can be fixed to the support frame 1 through the connecting seat 11, and the air pump 8 can be made firm.

[0030] Specifically, a fixing frame 14 is fixedly connected to the outer surface of the electronic valve 12. The bottom surface of the fixing frame 14 is fixedly connected to the upper surface of the support frame 1. In this embodiment, the electronic valve 12 can be fixed by the fixing frame 14. At the same time, the electronic valve 12 is an electric regulating valve that can accurately control the opening degree of the valve according to the feedback signal of the pressure sensor 16, thereby realizing the precise control of the pressure of the rubber sleeve 2.

[0031] Specifically, a sealing ring 15 is fixedly connected to the outer surface of the pressure sensor 16, and the bottom surface of the sealing ring 15 is fixedly connected to the outer surface of the connecting pipe 13. In this embodiment, the pressure sensor 16 can be supported on the support frame 1 through the sealing ring 15. At the same time, the pressure sensor 16 is a piezoresistive sensor with a fast response speed, which can quickly sense the instantaneous change in pressure inside the connecting pipe 13, allowing the control system to make timely adjustments for inflation or deflation.

[0032] The working principle and usage process of this utility model are as follows: First, connect the air pump 8, electronic valve 12, pressure sensor 16, and controller 10 to the power supply. Simultaneously, connect the air pump 8, electronic valve 12, and pressure sensor 16 to the controller 10 via wires. Then, fix the filter 3 to the support frame 1 using the fixing pin 4. Place the support frame 1 inside the FFU. Next, use the wires to activate the controller 10 to turn on the air pump 8. Simultaneously, the activation of the air pump 8 allows outside air to be transferred to the rubber sleeve 2 through the electronic valve 12 and connecting pipe 13. The rubber sleeve 2 is inflated by air, and the contact state between the rubber sleeve 2 and the inner wall of the FFU is observed. After the rubber sleeve 2 expands and fixes the support frame 1 inside the FFU, the air pump 8 is turned off by the controller 10, and the electronic valve 12 is opened to close the pipeline. Then, the parameters are set on the controller 10 according to actual needs, and the pressure sensor 16 senses the pressure in the rubber sleeve 2 and the connecting pipe 13. When the pressure sensor 16 senses a decrease in pressure, it transmits the signal to the controller 10, and the controller 10 then... The air pump 8 and electronic valve 12 are opened, allowing the air pump 8 to replenish air into the rubber sleeve 2 until the pressure sensor 16 senses that the pressure has returned to the set value. Then, the controller 10 closes the air pump 8 and electronic valve 12 again, ensuring that the rubber sleeve 2 is always in a suitable expansion state, firmly fixing the support frame 1 inside the FFU. During equipment operation, the filter 3 continuously filters the passing air, using ultra-fine glass fiber paper or polypropylene fiber filter media to efficiently filter particulate matter in the air through principles such as interception, inertial collision, diffusion, and electrostatic attraction. Microorganisms such as bacteria and viruses provide a high-cleanliness air environment for the space where the FFU is located. When it is necessary to disassemble or replace the filter 3, first open the electronic valve 12 through the controller 10 to expel the air in the rubber sleeve 2, causing the rubber sleeve 2 to contract and release the fixing effect on the support frame 1. Then, remove the support frame 1 from the FFU. By disconnecting the connection of the fixing pin 4, the filter 3 can be removed from the support frame 1 for replacement or maintenance. After the replacement is completed, fix the support frame 1 back into the FFU according to the above installation and inflation process to restore the equipment to normal operation.
