[0002] Fresh air purification equipment is a device used to improve indoor air quality. It maintains the freshness and comfort of indoor air by introducing fresh outdoor air into the room while expelling stale indoor air. This type of equipment can not only reduce indoor pollutants, but also effectively control indoor humidity and temperature, providing a healthier and more comfortable living environment.

[0003] Currently, existing fresh air purification equipment is usually fixed to the wall of a house. However, it is inconvenient to automatically control and adjust the efficiency of the fresh air delivery based on the indoor carbon dioxide content, which makes it difficult to deliver fresh air more effectively and also fails to reduce the cost of using the equipment.

[0004] Therefore, we propose a purification device that can deliver fresh air to solve the above problems. Utility Model Content

[0015] In summary, the technical effects and advantages of this application are as follows:

[0016] 1.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A purification device capable of delivering fresh air includes a base 1, a fixed box 2 fixedly connected to the upper surface of the base 1, and four fixing pins slidably connected to the inner wall of the base 1. Each fixing pin 4 has a caster wheel 3 fixedly connected to its bottom end, and the upper surface of each caster wheel 3 is in contact with the bottom surface of the base 1. By setting the caster wheel 3 and the fixing pins 4, the position of the device can be easily moved, and the fixing pins 4 can facilitate the installation and removal of the caster wheel 3.

[0025] The fixed box 2 is equipped with a fan 10 inside. The inner wall of the fixed box 2 is slidably connected with a support block 17. Each fixing pin 4 has a nut 9 threadedly connected to its outer surface. The bottom surface of each nut 9 is in contact with the upper surface of the base 1. By setting the nuts 9, the position of the caster 3 can be firmly fixed to prevent it from falling off during use.

[0026] A carbon dioxide sensor 18 is fixedly connected to the upper surface of the support block 17. The carbon dioxide sensor 18 is a device used to detect and measure the concentration of carbon dioxide in the environment. It can convert changes in carbon dioxide concentration into electrical signals and display or output the measurement results for monitoring and control. A controller 19 is fixedly connected to the bottom surface of the support block 17. Two filter plates 5 are set above the base 1. The sides of the two filter plates 5 that are close to each other are in contact with the two sides of the fixed box 2. By setting the filter plates 5, the incoming air can be filtered to prevent a large amount of dust from entering the device and the environment.

[0027] A servo motor 12 is fixedly connected to the inner bottom wall of the fixed box 2. A worm gear 13 is fixedly connected to the power output end of the servo motor 12. Four first bolts 6 are threadedly connected to the inner wall of each filter plate 5. The ends of each group of first bolts 6 that are close to each other are threadedly connected to the inner wall of the fixed box 2. By setting the first bolts 6, the position of the filter plate 5 can be firmly fixed, so that it can be used stably, and it can also be convenient for subsequent disassembly.

[0028] The top of the worm gear 13 is rotatably connected to the inner wall of the fixed box 2. Six worm wheels 14 are meshed on the outer surface of the worm gear 13. Handles 7 are fixedly connected to the front and back of the fixed box 2. Anti-slip sleeves 8 are fixedly connected to the outer surface of each handle 7. By setting handles 7 and anti-slip sleeves 8, it is easy for users to push the device to move, thus making it easy for staff to use.

[0029] Each worm gear 14 has a rotating shaft 15 fixedly connected to its inner wall. Both ends of each rotating shaft 15 are rotatably connected to the inner wall of the fixed box 2. Four support frames 11 are fixedly connected to the outer surface of the fan 10. The outer surface of each support frame 11 is fixedly connected to the inner wall of the fixed box 2. By setting the support frames 11, the fan 10 can be firmly fixed, avoiding instability during use.

[0030] An adjustment plate 16 is fixedly connected to the outer surface of each rotating shaft 15. The servo motor 12, carbon dioxide sensor 18 and fan 10 are all electrically connected to the controller 19 through wires. The inner wall of the support block 17 is threaded with two second bolts 20. The bottom end of each second bolt 20 is threaded to the inner wall of the fixed box 2. By setting the second bolts 20, the position of the support block 17 can be firmly fixed, and subsequent disassembly and replacement can also be carried out.

[0031] The working principle of this utility model is as follows: In use, the user first connects the power supply to the fan 10, servo motor 12, carbon dioxide sensor 18, and controller 19 of the device, ensuring a stable power supply. Then, the user pushes the device to a suitable position. Next, the user turns on the carbon dioxide sensor 18 and controller 19. After activation, the carbon dioxide sensor 18 detects the carbon dioxide content in the environment and sends the detected data to the controller 19 via an electrical signal for judgment. The controller 19 then controls the fan 10 to start based on the carbon dioxide content and adjusts the fan speed and intensity to a suitable level. After the temperature is reached, the fan 10 can quickly deliver a large amount of fresh air into the environment. At the same time, after the controller 19 judges the carbon dioxide content, it will also control the servo motor 12 to start. After the servo motor 12 is started, it can generate power to rotate. The rotation of the servo motor 12 can drive the worm gear 13 to rotate. Then, under the action of the rotation of the worm gear 13, it can drive the worm wheel 14 and the rotating shaft 15 to rotate. Finally, the rotating shaft 15 can drive the adjustment plate 16 on the surface of the rotating shaft 15 to flip. In this way, the size of the air inlet can be adjusted according to the carbon dioxide content, so that it can deliver fresh air more effectively and reduce the cost of equipment use.
