When the work is not needed, we only need to press the pressing part 1331 again, and the corresponding ventilation device will be closed, so that there will be no impact on the overall appearance, such as Fig.11 described.

[0036] This is achieved through the following scheme.

[0037] Please refer to the attached Figure 1-10 The main structure includes a box body 1, a wire hole 11 is provided at the bottom of the box body 1 for wiring, a socket part 12 is provided on one side of the box body 1, and a ventilation part 13 is provided on the other side.

A limiting ball 1336 is arranged on the inner wall of the pressing portion 1331 to match the pressing rotating groove 1335. Pressing the pressing portion 1331 causes the limiting ball 1336 to move in the pressing rotating groove 1335, so that the pressing rotating member 1333 rotates.

[0040] A limiting slot 1311 is provided in the limiting ring 131, and pop-up slots 1312 are provided on both sides of the limiting slot 1311.

[0041] The limiting ring 131 is provided with a second spring member 1334 , and the first limiting claw 1338 is engaged in the limiting slot 1311 to compress the second spring member 1334 , and the first limiting claw 1338 rotates into the pop-up slot 1312 , and the second spring member 1334 relaxes.

[0042] A pressing plate is provided on the top of the pressing portion 1331 , a plurality of air holes 3 are provided on the limiting plate 132 , and an air filter 4 is provided between the pressing plate and the limiting plate 132 .

[0043] The second spring member 1334 is fixedly disposed on the bottom of the clamping chassis 1337 .

[0044] A storage bin 5 for storing a limiting ball 1336 is disposed on the side wall of the pressing portion 1331 . A third spring component 6 is disposed in the storage bin 5 . The limiting ball 1336 is fixedly disposed on the third spring component 6 .

[0045] The pressing rotation groove 1335 includes a plurality of up-and-down moving grooves 7 and an angle rotation groove 8, one end of the angle rotation groove 8 contacts the top of the up-and-down moving groove 7, and the other end contacts the bottom of another adjacent up-and-down moving groove 7;

[0046] See attached Figure 6 The up-down moving groove 7 comprises a rotating portion 71, a transition portion 72 and a moving portion 73, wherein the rotating portion 71, the transition portion 72 and the moving portion 73 are arranged vertically in the up-down moving groove 7, and the transition portion 72 is located in the middle of the rotating portion 71 and the moving portion 73;

[0047] The moving portion 73 is lower than the depth of the angle rotation groove 8 to form a first step 81 , and the rotation portion 71 is deeper than the transition portion 72 to form a second step 82 , which is the same depth as the angle rotation groove 8 .

[0048] The interval between adjacent up-and-down moving slots 7 is 90 degrees, and the interval between the pop-up card slots 1312 on both sides is 180 degrees.

[0049] The limiting plate 132 is provided with a limiting hole 9 , and second limiting claws 91 are provided on both sides of the limiting hole 9 . Limiting sliding grooves 92 are provided on both sides of the cylinder wall of the pressing portion 1331 to cooperate with the second limiting claws 91 .

[0050] Directions:

[0051] The limiting plate 132 is provided with a limiting hole 9, and the limiting hole 9 is provided with a second limiting claw 91 on both sides. Based on the limiting sliding grooves 92 provided on both sides of the cylinder wall of the pressing part 1331 to cooperate with the second limiting claw 91, when the pressing part 1331 is pressed, the pressing part 1331 will only move up and down along the vertical direction. At this time, when the pressing part 1331 is pressed, refer to the attached Figure 6The pressing portion 1331 has a storage bin 5 on its side wall for storing a limiting ball 1336. A third spring member 6 is provided in the storage bin 5. The limiting ball 1336 is fixedly arranged on the third spring member 6. The limiting ball 1336 moves in a pressing and rotating groove 1335 on the side wall of the pressing and rotating member 1333. Due to the special design of the pressing and rotating groove 1335, refer to the attached Figure 3 , 6 , 7, 8, when the limiting ball 1336 moves in the angle rotation slot 8, it will drive the pressing rotating member 1333 to rotate. At the same time, a clamping chassis 1337 is provided at the bottom of the pressing rotating member 1333. The clamping chassis 1337 will rotate with the rotation of the pressing rotating member 1333. At the same time, a limiting slot 1311 is provided in the limiting ring 131, and pop-up slots 1312 are provided on both sides of the limiting slot 1311. First limiting claws 1338 are provided on both sides of the clamping chassis 1337. The first limiting claws 1333 8 is clamped in the limiting slot 1311, and the width of the first limiting claw 1338 is matched with the pop-up slot 1312; a second spring member 1334 is provided in the limiting ring 131. When ventilation is not needed at the beginning, the first limiting claw 1338 is clamped in the limiting slot 1311 to compress the second spring member 1334. As the above procedure proceeds, the first limiting claw 1338 is pressed and rotated to rotate into the pop-up slot 1312, and the second spring member 1334 is relaxed, and the pressing portion 1331 is opened accordingly.

[0052] It should be noted that in order to enable the limiting ball 1336 to move according to the path we specified, refer to the attached Figure 6-8 In state 1, the limiting ball 1336 enters the up-and-down moving groove 7 from the angle rotation groove 8, see the attached Figure 6-7 The moving portion 73 is lower than the depth of the angle rotation groove 8 to form a first step 81. When the limiting ball 1336 passes the bottom, due to the existence of the first step 81, the limiting ball 1336 will move along a lower path, that is, along the up and down moving groove 7, and the limiting ball 1336 is restricted to return along the original path. State 2, refer to the attached Figure 8 The depth of the rotating portion 71 is greater than the depth of the transition portion 72 to form a second step 82, and is the same as the depth of the angle rotation groove 8. The same as the above principle, when pressing continues, the limiting ball 1336 will move along the angle rotation groove 8 to prevent the limiting ball 1336 from returning along the original path. Therefore, a third spring component 6 is provided in the storage bin 5, and the limiting ball 1336 is fixedly arranged on the third spring component 6.

[0053] At the same time, an air filter 4 is provided between the pressing plate and the limiting plate 132. Figure 2As described above, when the device pops up, it can be taken out immediately. The whole device is made of plastic structure, and only second limiting claws 91 are provided on both sides of the limiting hole 9, which have a little limiting effect on the pressing part 1331, but it can be removed and the air filter 4 can be replaced.
