[0012] (III) Beneficial effects
[0013] Compared with the prior art, the present utility model provides a novel fresh air exhaust device, which has the following
[0014] beneficial effects:
[0015] 1. For this novel fresh air exhaust device, through the cooperation between the pulley and the convex block, when the pulley moves upward, it will drive the displacement of the cross plate by pushing the convex block. The movement of the cross plate will drive the displacement of the clamping block to block the sliding block. At this time, the sliding block will be fixed in the machine body, so that the filter screen can be stably installed in the machine body. When the pulley moves back and no longer pushes the convex block, the clamping block will disengage from the sliding block, enabling the operator to easily take out the filter screen for cleaning, facilitating the work of the operator and increasing the scope of use of the device.
[0016] 2. For this novel fresh air exhaust device, by setting the cross plate to be slidably connected to the outer side of the limiting rod, on the one hand, the limiting rod maintains the balance of the cross plate during movement, preventing the cross plate from losing balance and shaking during movement, ensuring the normal displacement of the cross plate. On the other hand, the limiting rod restricts the movement direction of the cross plate, preventing the device from failing due to misalignment of the cross plate, and ensuring the normal use of the device.
[0017] 3. For this novel fresh air exhaust device, by setting the spring, when the pulley displaces and pushes the convex block, the spring will be squeezed by the cross plate. When the pulley moves back and no longer pushes the convex block, the spring will drive the clamping block to move back by bouncing the cross plate back, so that the clamping block can quickly move back to the initial position, ensuring the reuse of the device. Moreover, the cost of the spring is low and it is suitable for promotion. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1-3 , the present invention provides a technical solution: a new type of fresh air and exhaust air equipment, including a body 1, two groups of mounting plates 13 clamped inside the body 1, and a filter net 2 fixedly arranged inside the mounting plates 13. Sliders 3 are fastened on both the left and right sides of the mounting plate 13, and the sliders 3 are slidably connected inside the body 1. Two groups of springs 11 are respectively fastened on both the left and right sides of the body 1, and the right ends of the two groups of springs 11 are fastened to the horizontal plate 14. By setting the spring 11, when the pulley 7 displaces and pushes the convex block 8, the spring 11 will be squeezed by the horizontal plate 14, and when the pulley 7 moves back and no longer pushes the convex block 8, the spring 11 will drive the clamping block 12 to move back by elastically moving the horizontal plate 14 back, so that the clamping block 12 can quickly move back to the initial position, ensuring the reuse of the device, and the cost of the spring 11 is low and suitable for popularization. Clamping blocks 12 are fastened on both the front and back sides of the horizontal plate 14, and the clamping blocks 12 are slidably connected inside the body 1. A convex block 8 is fastened on the right side of the horizontal plate 14. Motors 15 are fixedly arranged on both the left and right sides of the body 1. The output end of the motor 15 is key-connected with a threaded pipe 17. A sleeve 16 is screwed on the outside of the threaded pipe 17. A connecting plate 4 is fastened on the right side of the sleeve 16. A support frame 6 is fastened on the right side of the connecting plate 4. A central shaft 5 is fastened on the top of the support frame 6. A pulley 7 is movably sleeved on the outside of the central shaft 5. The convex block 8 is a semi-elliptical convex block, and the thickness of the convex block 8 is greater than the thickness of the pulley 7. Through the cooperation between the pulley 7 and the convex block 8, when the pulley 7 moves upward, it will drive the horizontal plate 14 to displace by pushing the convex block 8, and the movement of the horizontal plate 14 will drive the clamping block 12 to displace and block the slider 3. At this time, the slider 3 will be fixed inside the body 1, so that the filter net 2 can be stably installed inside the body 1. When the pulley 7 moves back and no longer pushes the convex block 8, the clamping block 12 will disengage from the slider 3, enabling the operator to easily take out the filter net 2 for cleaning, facilitating the work of the operator and increasing the use range of the device.
[0024] Specifically, in order to protect the motor 15 and the threaded tube 17, protective covers 10 are fastened on both the left and right sides of the machine body 1. The protective covers 10 are located outside the motor 15 and the threaded tube 17, and thus the motor 15 and the threaded tube 17 can be protected by the protective covers 10.
[0025] Specifically, in order to maintain the balance of the cross plate 14, two groups of limiting rods 18 are fastened on both the left and right sides of the machine body 1 respectively. The cross plate 14 is slidably connected to the outside of the two groups of limiting rods 18. A blocking block 9 is fastened on the outside of the limiting rods 18. The blocking block 9 is located on the right side of the cross plate 14, and the blocking block 9 is a silicone blocking block. Thus, by setting the cross plate 14 to be slidably connected to the outside of the limiting rods 18, on the one hand, the limiting rods 18 maintain the balance of the cross plate 14 during movement, preventing the cross plate 14 from losing balance and shaking during movement, ensuring the normal displacement of the cross plate 14. On the other hand, the limiting rods 18 limit the movement direction of the cross plate 14, preventing the device from failing due to the misalignment of the cross plate 14, and ensuring the normal use of the device.
[0026] Specifically, in order to prevent the pulley 7 from detaching from the central shaft 5, two groups of anti - detachment blocks are fastened on the outside of the central shaft 5, and the two groups of anti - detachment blocks are respectively located on the front and back sides of the pulley 7. Thus, the pulley 7 can be blocked by the anti - detachment blocks.
[0027] The electrical components mentioned in this article are all electrically connected to the external main controller and the 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.
[0028] During use, the motor 15 is turned on so that its output end drives the threaded tube 17 to rotate. The rotation of the threaded tube 17 will drive the sleeve 16 to move upward. The upward movement of the sleeve 16 will drive the central shaft 5 and the pulley 7 to move upward through the connecting plate 4 and the support frame 6. The upward movement of the pulley 7 will drive the cross plate 14 to displace by pushing the convex block 8. The movement of the cross plate 14 will drive the block 12 to displace and block the slider 3. At this time, the slider 3 will be fixed in the machine body 1, enabling the filter net 2 to be stably installed in the machine body 1. During disassembly, the output end of the motor 15 is controlled to drive the threaded tube 17 to reverse. The reverse rotation of the threaded tube 17 will drive the pulley 7 to move downward by driving the sleeve 16 to move downward and no longer push the convex block 8. At this time, the spring 11 will drive the block 12 to move back by elastically moving the cross plate 14 back, so that the block 12 can quickly move back to the initial position and no longer block the slider 3. Then the operator can conveniently take out the mounting plate 13 to clean the filter net 2 conveniently.
[0029] In summary, for this new fresh air and exhaust equipment, through the cooperation between the pulley 7 and the convex block 8, when the pulley 7 moves upward, it will drive the horizontal plate 14 to displace by pushing the convex block 8. The movement of the horizontal plate 14 will drive the latch 12 to displace and block the slider 3. At this time, the slider 3 will be fixed in the machine body 1, enabling the filter net 2 to be stably installed in the machine body 1. When the pulley 7 moves back and no longer pushes the convex block 8, the latch 12 will disengage from the slider 3, allowing the operator to easily remove the filter net 2 for cleaning, facilitating the work of the operator and increasing the scope of use of this device.
[0030] For this new fresh air and exhaust equipment, by arranging the horizontal plate 14 to be slidably connected to the outside of the limiting rod 18, on the one hand, the limiting rod 18 maintains the balance of the horizontal plate 14 during movement, preventing the horizontal plate 14 from losing balance and wobbling during movement, ensuring the normal displacement of the horizontal plate 14. On the other hand, the limiting rod 18 restricts the movement direction of the horizontal plate 14, preventing the device from failing due to the misalignment of the horizontal plate 14 and ensuring the normal use of this device.
[0031] For this new fresh air and exhaust equipment, by arranging the spring 11, when the pulley 7 displaces and pushes the convex block 8, the spring 11 will be squeezed by the horizontal plate 14. When the pulley 7 moves back and no longer pushes the convex block 8, the spring 11 will drive the latch 12 to move back by bouncing the horizontal plate 14 back, so that the latch 12 can quickly move back to the initial position, ensuring the reuse of this device. Moreover, the cost of the spring 11 is low and it is suitable for popularization.
