[0024] Example 1:

[0025] like Figures 1 to 4, This embodiment provides a building energy-saving ventilation device that is easy to maintain, mainly comprising an air inlet square tube 1, an exhaust fan 2, a mounting frame 3, a filter 4 and a clamping member 5. The exhaust fan 2 is mounted inside the air inlet square tube 1, and the filter 4 is mounted on the inner wall of the mounting frame 3. The mounting frame 3 is movably embedded in the opening of the air inlet end of the air inlet square tube 1 to ensure the stability of the mounting frame 3. Two positioning grooves 11 are constructed on the air inlet end of the air inlet square tube 1. Positioning plates 31 are fixed on both sides of the mounting frame 3. The two positioning plates 31 are movably embedded in the inside of the two positioning grooves 11 respectively. Buckle and pull grooves 32 are opened through the positioning plates 31. There are two clamping members 5 and they are respectively mounted on the two positioning plates 31. Maintenance personnel can use two By holding the two positioning plates 31 and controlling the clip 5 with fingers, the mounting frame 3 and the air inlet square tube 1 can be fixed or released. When the filter 4 needs to be replaced, the mounting frame 3 only needs to be quickly released by the clip 5, and then the old filter 4 is taken out, and the new filter 4 is put in, and the mounting frame 3 is fixed again by the clip 5. Through the design of the clip 5, maintenance personnel can quickly replace the filter 4, which greatly shortens the maintenance time. The clip 5 is designed on the positioning plate 31, and the maintenance personnel can control the clip 5 with simple finger operation to quickly fix or release the filter 4, which simplifies the maintenance process. The design of the clip 5 reduces the damage caused by multiple twisting and extends the service life of the equipment.

[0026] See also Figure 2 、 Figure 3 and Figure 4 , a fixing hole 12 is constructed on the inner wall of the positioning groove 11, and a mounting groove 33 is constructed inside the positioning plate 31. The clamping member 5 includes a mounting block 51 movably arranged inside the mounting groove 33. Two fixing rods 52 that movably penetrate the positioning plate 31 are fixed on one side of the mounting block 51. A spring 53 is connected between the side of the mounting block 51 facing away from the two fixing rods 52 and the inner wall of the mounting groove 33. The end of one of the fixing rods 52 is movably inserted into the interior of the fixing hole 12, and the other fixing rod 52 is used for maintenance personnel to press. During the specific disassembly operation, the maintenance personnel pass their two palms through the two buckle grooves 32 and hold one end of the positioning plate 31, and press the thumb A fixing rod 52 in the pressing card connector 5 causes the fixing rod 52 at the other end to disengage from the fixing hole 12. The maintenance personnel pulls the two positioning plates 31 to release the fixing of the installation frame 3 and the air inlet square tube 1, and clean the filter screen 4. During installation, the same operation can be performed. Through the cooperation of the fixing rod 52 and the fixing hole 12, fast fixing and releasing can be achieved, which improves the maintenance efficiency. The maintenance personnel only needs to press simply to complete the insertion and removal of the fixing rod 52, which simplifies the maintenance process. The setting of the spring 53 can enable one of the fixing rods 52 to be stably inserted into the inside of the fixing hole 12, ensuring the stable fixation of the installation frame 3.

[0027] See also Figure 3 and Figure 4 The side edges of the buckle groove 32 and the side edges of the positioning plate 31 are both rounded. The rounded corner design reduces the risk of maintenance personnel being cut by sharp edges during operation and improves the safety of operation.

[0028] Example 2:

[0029] In this example, see Figure 3 and Figure 4 The mounting groove 33 passes through one side of the positioning plate 31 to accommodate the clip 5. The mounting groove 33 passes through one side of the positioning plate 31, making the assembly of the clip 5 simpler and more convenient, reducing assembly time, and precise mounting groove 33 helps to ensure the correct positioning of the clip 5 and reduce assembly errors. The simplified assembly design makes it easier to inspect and replace the clip 5 in the future; one side of the positioning plate 31 is fitted with an iron sheet 34 that can cover the opening of the mounting groove 33. The iron sheet 34 is fixed to the positioning plate 31 by screws. The iron sheet 34 covers the opening of the mounting groove 33, which can protect the internal clip 5 and other components from dust and impurities. The use of the iron sheet 34 simplifies the assembly process.

[0030] See also Figure 4 A guide rod 54 is fixed on the side of the mounting block 51 facing away from the fixed rod 52 and on the inner wall of the mounting groove 33. The two guide rods 54 are located on the same straight line. The two ends of the spring 53 are respectively mounted on the two guide rods 54. The guide rods 54 ensure that the spring 53 is stably compressed, thereby increasing the practical life of the spring 53. At the same time, it limits the position of the spring 53 to avoid deviation and facilitates the assembly of the spring 53.

[0031] See also Figure 4 A pressure plate 55 is installed at the end of the other fixed rod 52. The setting of the pressure plate 55 makes it convenient for maintenance personnel to operate with their fingers, while increasing the pressing area and reducing damage to the fingers when pressing; an external thread is provided on the outer peripheral side of the end of the other fixed rod 52, and one end of the pressure plate 55 is threadedly sleeved on the end of the other fixed rod 52. The threaded connection simplifies the assembly process of the pressure plate 55 and the fixed rod 52, and improves the assembly efficiency.

[0032] Working steps:

[0033] Step 1: First, the maintenance personnel puts both palms through the two buckle grooves 32, then holds one end of the positioning plate 31, and then presses the pressing plate 55 with the thumb to drive one of the fixing rods 52 to move into the inside of the positioning plate 31. Then, the maintenance personnel moves the installation frame 3 so that the installation frame 3 is embedded in the opening of the air inlet square tube 1, and the two positioning plates 31 are embedded in the inside of the two positioning grooves 11. Finally, release the thumb, and under the elastic force of the spring 53, one of the fixing rods 52 is inserted into the inside of the fixing hole 12 to complete the installation;

[0034] Step 2: First, the maintenance personnel puts his palms through the two buckle grooves 32, then holds one end of the positioning plate 31, and then presses the pressure plate 55 with his thumb to drive one of the fixing rods 52 out of the fixing hole 12. At this time, pull the two positioning plates 31 to separate the mounting frame 3 from the air inlet square tube 1, making it easier to clean the filter 4.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
