[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figures 1-3 The present invention provides the following technical solution:

[0032] The auxiliary fixing structure for the cleanroom air supply outlet filter includes:

[0033] Outer shell 1;

[0034] Filter 2, located at the bottom of housing 1;

[0035] Fastening nut 4 is fixedly connected to the lower end of the outer casing 1;

[0036] The filter fixing part 3 is threadedly connected to the circumferential surface of the fastening nut 4, and the filter fixing part 3 is in contact with the filter 2;

[0037] Column 6 is fixedly connected to the lower end of the outer casing 1;

[0038] Fixed housing 5 is fixedly connected to the lower end of filter 2;

[0039] Insert rod 7 is fixedly connected inside the fixed shell 5 and passes through the column 6;

[0040] Spring 8 is fixedly connected to the inner wall of one side of the fixed shell 5, and spring 8 is sleeved on the circumferential surface of the insertion rod 7;

[0041] The limiting piece 9 is fixedly connected to the circumferential surface of the insert rod 7, and one side of the spring 8 is in contact with the limiting piece 9.

[0042] In a specific embodiment of this utility model, the outer shell 1 is rectangular box-shaped, used to house the filter 2 and protect the internal structure. The filter 2 is made of high-efficiency filter material and is used to purify air. The fastening nut 4 is made of stainless steel and is used to fix the filter fixing part 3. The filter fixing part 3 is threaded onto the circumferential surface of the fastening nut 4 and contacts the filter 2 to fix the filter 2. The column 6 is made of stainless steel and is used to support the fixing shell 5. The fixing shell 5 is used to fix the insertion rod 7. The insertion rod 7 penetrates the column 6 and is made of stainless steel to transmit the elastic force of the spring 8. The spring 8 pushes the insertion rod 7 into the column 6 to filter the filter 2. The fixed limiting plate 9, made of stainless steel, contacts one side of the spring 8 and is used to limit the compression stroke of the spring 8. Through the cooperation of the filter fixing part 3, the fastening nut 4 and the column 6, the filter 2 is more firmly fixed, improving stability and safety. The setting of the spring 8 effectively buffers the weight of the filter 2, reduces vibration and noise, and extends the service life of the filter 2. The design of the limiting plate 9 ensures that the compression stroke of the spring 8 is within a reasonable range, preventing excessive compression that could damage the spring 8. In this device, multiple sets of filter fixing parts 3, fastening nuts 4, fixing shell 5, column 6, insertion rod 7, spring 8 and limiting plates 9 are provided.

[0043] Please refer to the details. Figures 1-3 The filter fixing part 3 has a matching thread with the fastening nut 4 so that it can be connected or disconnected from the fastening nut 4 by rotation.

[0044] In this embodiment, the filter retainer 3 has a thread that matches the fastening nut 4. This thread is designed as a standard external thread to facilitate mating with the internal thread of the fastening nut 4. The filter retainer 3 is made of stainless steel to ensure good mechanical strength and corrosion resistance. The threaded connection makes the connection between the filter retainer 3 and the fastening nut 4 more secure, improving the stability of the filter.

[0045] Please refer to the details. Figures 1-3 The insertion rod 7 can extend and retract inside the column 6 to adapt to the length adjustment needs in different installation environments.

[0046] In this embodiment, one end of the insertion rod 7 is fixedly connected to the fixed housing 5, and the other end protrudes from the outside of the column 6 to facilitate length adjustment. The telescopic design allows the insertion rod 7 to adapt to the height differences of different installation environments, improving the versatility of the structure. The telescopic function of the insertion rod 7 makes filter replacement and maintenance more convenient, improving the overall efficiency and reliability of the cleanroom air supply system.

[0047] Please refer to the details. Figures 1-3 The support column 6 is a hollow shell design, which reduces weight and increases stability.

[0048] In this embodiment, the column 6 is made of lightweight metal or high-strength plastic and is designed as a hollow tubular structure, i.e., a hollow shell design, which reduces the weight of the column 6 itself while maintaining its structural strength. The lightweight column 6 makes it easier to maintain and replace the filter.

[0049] Please refer to the details. Figures 1-3 The surface of the filter fixture 3 is designed to be smooth.

[0050] In this embodiment, the smooth surface of the filter fastener 3 reduces friction when it comes into contact with the fastening nut 4 and the filter 2, making the installation and disassembly process smoother. The smooth surface without burrs avoids damage to the filter 2 during installation, ensuring the integrity of the filter. The smooth surface is also less prone to accumulating dust and dirt, making it easy to perform daily cleaning and maintenance.

[0051] Please refer to the details. Figures 1-3 The column 6 comes into contact with the filter 2.

[0052] In this embodiment, the contact between the column 6 and the filter 2 ensures that the filter 2 can be effectively supported and fixed after installation. The contact between the column 6 and the filter 2 provides additional support for the filter, reducing vibration and displacement during use. The supporting role of the column 6 helps protect the filter 2 from damage and extends its service life.

[0053] The working principle and usage process of this utility model are as follows: Place the filter 2 at the bottom of the outer shell 1, thread the filter fixing part 3 onto the circumferential surface of the fastening nut 4, and ensure that the filter fixing part 3 is in contact with the filter 2. Pull the insertion rod 7, and the spring 8 will be compressed. After the filter 2 is installed, release the insertion rod 7, and the spring 8 will spring the insertion rod 7 back and insert it into the opening of the column 6 to limit the filter 2 and protect its stability. Check whether all connecting parts are firm and ensure that the filter 2 is stably fixed in the outer shell 1. After confirming that everything is correct, close the outer shell 1 to complete the installation of the cleanroom air supply outlet filter.

[0054] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
