DETAILED DESCRIPTION

[0020] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figures 1-4 As shown, a primary filter cotton type fresh air window for a machine room which is easy to disassemble and replace comprises a ventilation room body 1 and a filter screen 2. A quick-release structure 3 is arranged on the ventilation room body 1. The quick-release structure 3 comprises two fixed frames 4 symmetrically mounted on the surface of the ventilation room body 1. A support block 5 is movably mounted inside the fixed frame 4. A plurality of first springs 6 connected to the inner wall of the fixed frame 4 are fixedly mounted on one side of the support block 5. Support rods 7 are fixedly mounted on the top and bottom of the support block 5. A clamping block 8 is fixedly mounted on one side of the support rod 7. A plurality of clamping slots 9 for use with the clamping block 8 are opened on the filter screen 2. A quick-release structure 3 is used to replace the traditional welding or bolt connection method to install and fix the ventilation room body 1 and the filter screen 2; specifically, after the filter screen 2 is placed on the ventilation room body 1, the multiple first springs 6 contract to drive the support block 5 to move, and then drive the support rod 7 and the block 8 to move, until the block 8 is inserted into the slot 9 opened on both sides of the filter screen 2, and under the continuous contraction of the multiple first springs 6, the filter screen 2 is pressed and fixed on the ventilation room body 1 as a whole; and when disassembling, the block 8 can be directly pulled outward to disengage it from the slot 9, so as to facilitate and quickly disassemble the filter screen 2 from the ventilation room body 1, so as to facilitate timely replacement of the filter screen 2 when it is damaged or blocked, so as to avoid affecting the ventilation effect and ventilation efficiency of the fresh air window of the ventilation room body 1.

[0022] like Figures 1-3As shown, the volume of the clamping block 8 matches the volume of the clamping groove 9; on the other side of the support block 5, a plurality of fixing rods 10 are fixedly installed, and a handle 11 is fixedly installed at one end of the two fixing rods 10 extending outside the fixing frame 4; a positioning frame 12 is fixedly installed on one side of the fresh air machine room body 1, and a positioning groove 13 is opened at the bottom of the filter net 2. The clamping block 8 is set to match the clamping groove 9, so that the clamping block 8 can be tightly clamped in the clamping groove 9 to firmly install the filter net 2 and prevent it from loosening and shaking; one end of the fixing rod 10 is connected to the handle 11 and extends outside the fixing frame 4, which can facilitate pulling the support block 5 when disassembling the filter net 2; the setting of the positioning frame 12 and the positioning groove 13 places the filter net 2 on the positioning frame 12 before fixing it. At this time, the positioning groove 13 at the bottom of the filter net 2 is clamped with the positioning frame 12 on the fresh air machine room body 1, and after the two come into contact, it can play a role in positioning and supporting the filter net 2, enabling the clamping block 8 to be inserted into the clamping groove 9 more easily and accurately.

[0023] As Figures 2-4 shown, a sealing gasket 14 is fixedly installed on one side of the filter net 2, and a sealing groove 15 for cooperating with the sealing gasket 14 is opened on the fresh air machine room body 1; a fixing bracket 16 is fixedly installed on one side of the fixing frame 4, a clamping rod 17 is movably installed on the fixing bracket 16, a plurality of second springs 18 connected to the clamping rod 17 are fixedly installed on one side of the fixing bracket 16, and a limiting groove 19 is opened on the support block 5; one end of the clamping rod 17 is conical and extends into the fixing frame 4.
