[0017] On the contrary, as the number of people in the room decreases, the air volume can be reduced accordingly, and the air outlet angle is reduced accordingly, that is, the angle between the exhausted air and the horizontal direction is reduced, which can reduce the exhaust range to ensure the air circulation speed in the area, reduce the risk of infectious aerosol transmission, and save energy loss to a certain extent;

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0034] See also Figure 1-Figure 10 The present invention provides an internal circulation air purification device, including an air inlet component 1, an air outlet component 2 and a pipe 3 connected between the air inlet component 1 and the air outlet component 2.

[0035] The air intake assembly includes a cabinet 11, a first air guide port 12 is provided on the top of the cabinet 11, an air inlet 13 is provided at the bottom of one side of the cabinet 11, a medium efficiency filter (not shown) is installed at the air inlet 13, and an induced draft fan (not shown) is installed in the cabinet 11 above the medium efficiency filter; the air outlet assembly 2 includes an exhaust box 21, a square exhaust port is provided at the bottom of the exhaust box 21, and an exhaust mechanism 4 is installed at the exhaust port, a second air guide port 23 is provided on one side of the exhaust box 21, and both ends of the pipeline 3 are respectively connected to the second air guide port 23 and the first air guide port 12;

[0036] like Figure 7 As shown, the device is used in the emergency department of a hospital. When installed, the cabinet 11 is placed close to the indoor wall of the emergency department, and the exhaust box 21 is installed in the indoor ceiling of the emergency department. The two ends of the pipe 3 are respectively connected to the second air guide port 23 and the first air guide port 12 to realize the connection between the exhaust box 21 and the cabinet 11. During epidemic or flu seasons, peak traffic and other periods, the induced draft fan is started to suck in the indoor air of the emergency department from the air inlet 13 and filter and purify it through the medium efficiency filter. It is then discharged from the first air guide port 12 and introduced into the exhaust box 21 through the pipe 3, and then discharged through the exhaust mechanism 4, so that the indoor air of the emergency department flows from top to bottom and is purified, so as to reduce the risk of infectious aerosol transmission.

[0037] Furthermore, the cabinet may be installed with air purification systems such as ultraviolet light, static electricity, photocatalysis and ion.

[0038] In actual use, in order to ensure the air purification effect, the number of the devices can be adaptively set according to the size of the indoor space, that is, the number of the devices can be increased when the indoor space is larger.

[0039] As for the air purification effect, a faster air circulation speed means a better air purification effect, while a slower air circulation speed means a worse air purification effect. In order to ensure the air purification effect, the air circulation speed should be reasonably controlled.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, the exhaust mechanism 4 includes a base member 41, four exhaust plates 43 and a driving assembly 44. The base member 41 is in the shape of a quadrangular pyramid as a whole and protrudes toward the side away from the exhaust box 21. Four ventilation slots 42 are provided on the four sides of the base member 41. The four exhaust plates 43 are respectively rotatably adapted in the four ventilation slots 42. The exhaust plates 43 can be driven by the driving assembly 44 to rotate between a first position and a second position with the bottom edge of the corresponding base member 41 as the central axis. When the exhaust plates 43 are in the first position, the exhaust plates 43 are flush with the bottom surface of the base member 41 (as shown in FIG. 1 ). Figure 3 and Figure 5 As shown in FIG. 1 ), when the exhaust plate 43 is in the second position, the exhaust plate 43 is flush with the side surface corresponding to the base member 41 (as shown in FIG. 1 ). Figure 4 and Figure 6 As shown), the exhaust plate 43 is evenly provided with exhaust slots 431, and when the exhaust volume increases, the driving component 44 drives the exhaust plate 43 to rotate toward the second position, and when the exhaust volume decreases, the driving component 44 drives the exhaust plate 43 to rotate toward the first position.

[0041] When the purified air enters the exhaust box 21, it will be discharged from the exhaust slot 431 of the exhaust plate 43. During this process, when there are a large number of people in the room, the air intake of the air inlet 13 and the exhaust volume of the exhaust slot 431 can be increased by increasing the rotation speed of the induced draft fan. At this time, due to the increase in exhaust volume, the drive component 44 drives the exhaust plate 43 to rotate toward the second position, the inclination of the exhaust plate 43 increases, and the angle between the air discharged from the exhaust slot 431 of the exhaust plate 43 and the horizontal direction increases. The air will diffuse to the surroundings to increase the exhaust range and increase the range of indoor air circulation, thereby improving the purification effect of a large range in the room and reducing the risk of infectious aerosol transmission. It is worth mentioning that since the exhaust volume and air intake of the device are increased, it will not affect the air circulation speed of the device, and the air purification effect can be ensured.

[0042] When there are fewer people in the room, the speed of the induced draft fan can be lowered to reduce the loss of electric energy. At this time, due to the reduction in the speed of the induced draft fan, the air intake volume of the air inlet 13 and the exhaust volume of the exhaust slot 431 are also reduced accordingly. The driving component 44 drives the exhaust plate 43 to rotate toward the first position, the inclination of the exhaust plate 43 is reduced, and the angle between the air discharged from the exhaust slot 431 of the exhaust plate 43 and the horizontal direction is reduced, which can reduce the exhaust range to ensure the air circulation speed in the area and reduce the risk of infectious aerosol transmission.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, in a specific embodiment of the present invention, a 5-speed speed regulating switch 5 for adjusting the speed of the induced draft fan is provided on the cabinet 11. When in use, the air intake and exhaust volumes of the device can be adjusted by the speed regulating switch 5. When the air intake and exhaust volumes are the minimum, the exhaust plate 43 is in the first position, and when the air intake and exhaust volumes are the maximum, the exhaust plate 43 is in the second position.

[0044] like Fig. 9 As shown, in a specific embodiment of the present invention, the base member 41 includes four L-shaped corner columns 411 respectively arranged at four corners of the air outlet and a central base 412 connected to the four L-shaped corner columns 411. The central base 412 includes a central body 4121 and four triangular plates 4122 scatteredly distributed on the outside of the central body 4121 in a circumferential direction. The four triangular plates 4122 are fixedly connected to the four L-shaped corner columns 411. A positioning shaft 413 parallel to the side of the corresponding air outlet is arranged between adjacent L-shaped corner columns 411. A through groove is formed between adjacent triangular plates 4122, the central base 412 and the positioning shaft 413. The air outlet plate 43 is in an isosceles trapezoidal shape. A sleeve 432 is arranged on one side of the bottom edge of the air outlet plate 43. The sleeve 432 is rotatably arranged on the positioning shaft 413. The sleeve 432 of the air outlet plate 43 can rotate on the positioning shaft 413, thereby realizing the rotation of the air outlet plate 43 between the first position and the second position.

[0045] like Figure 8 and Fig. 9 As shown, in a specific embodiment of the present invention, the cross section of the sleeve 432 is equal to the diameter of the transverse surface of the L-shaped corner column 411, and the four corner columns and the four sleeves 432 together form a square frame with a circular cross section; a covering frame 45 is also provided at the exhaust port, and the square frame is provided in the covering frame 45. The exhaust mechanism 4 can be connected to the exhaust box 21 through the covering frame 45, and the covering frame 45 also seals the sleeve 442 of the exhaust plate 43.

[0046] like Fig.10 As shown, in a specific embodiment of the present invention, the central base 412 is hollow to form a chamber 4123 with an open top, and the driving assembly 44 includes a linkage component and a driving source. The linkage component includes a connecting rod 441 respectively arranged at the top of the end of the exhaust plate 43 away from the central body 4121, a sleeve 442 vertically arranged in the chamber 4123, and a sliding column 443 slidably arranged in the sleeve 442. The top end of the connecting rod 441 extends to the top of the base member 41, and four telescopic rods 444 are vertically fixed on the outer side of the top of the sliding column 443 along the circumferential direction. The telescopic end of the telescopic rod 444 is hinged to the top of the connecting rod 441, and the driving source is used to drive the sliding column 443 to slide vertically. When in use, the driving source can drive the sliding shaft to slide axially in the sleeve 442. When the driving source drives the sliding column 443 to move upward in the sleeve 442, the sliding column 443 moves upward through the four telescopic rods 444 and the four connecting rods 441. At this time, the sleeves 442 of the four exhaust plates 43 can rotate on the positioning shaft 413, thereby causing the exhaust plates 43 to rotate toward the first position, and the telescopic rod 444 extends during this process; when the driving source drives the sliding column 443 to move downward in the sleeve 442, the sliding column 443 moves downward through the four telescopic rods 444 and the four connecting rods 441. At this time, the sleeves 442 of the four exhaust plates 43 can rotate on the positioning shaft 413, thereby causing the exhaust plates 43 to rotate toward the second position, and the telescopic rod 444 shortens during this process.

[0047] In a specific embodiment of the present invention, the driving source includes a rotating shaft 445 coaxial with the pipe 3, the rotating shaft 445 has a driving end 4451 extending into the pipe 3 and a passive end 4452 extending into the exhaust box 21, the driving end 4451 is equipped with a fan blade 446, and a gear box 447 is also fixed on the top of the exhaust box 21, the input shaft of the gear box 447 is fixedly connected to the passive end 4452 of the rotating shaft 445, and the output shaft of the gear box 447 is fixedly connected to a turntable 448, and the turntable 448 is away from the gear box A column 449 is provided on one side of 447; a vertical rod 4491 is fixed on the top of the sliding column 443, and a horizontal rod 4492 is provided on the top of the vertical rod 4491, the vertical rod 4491 and the horizontal rod 4492 form a T-shape, a sliding groove 4493 is provided in the horizontal rod 4492, the column 449 slides and fits in the sliding groove 4493, a spring rod 4494 is provided between the top ends of the horizontal rod 4492 and the top of the exhaust box 21, when the spring rod 4494 is in a normal state, the sliding column 443 is at the uppermost end of its sliding stroke.

[0048] Based on the above design, when the air in the duct 3 enters the exhaust box 21, the air in the duct 3 will cause the fan to rotate, thereby causing the rotating shaft 445 to rotate, and the rotation of the rotating shaft 445 can drive the output end of the gear box 447 to rotate. At this time, the gear set in the gear box 447 can convert the high-speed rotation input at its input end into a low-speed and high-torque rotation output from its output end, thereby causing the turntable 448 to rotate; the turntable 448 rotates, and through the cooperation of its column 449 and the sliding groove 4493 of the cross bar 4492, the cross bar 4492 can move downward and stretch the spring rod 4494 above the cross bar 4492. In this process, the cross bar 4492 moves downward through the vertical rod 4491, which can cause the sliding column 443 to move downward in the sleeve 442, that is, drive the exhaust plate 43 to rotate toward the second position to increase its exhaust range;

[0049] In the above process, as the crossbar 4492 moves downward continuously, the elastic force of the spring rod 4494 increases continuously. When the torque output from the gear box 447 is less than the elastic force of the spring rod 4494, the turntable 448 is locked. At this time, the fan stops rotating and the exhaust plate 43 is locked at this position.

[0050] The rotation of the turntable 448 will drive the cross bar 4492 to move upward, thereby causing the sliding column 443 to move upward in the sleeve 442, that is, drive the exhaust plate 43 to move upward. In this process, the turntable 448 will continue to rotate and drive the cross bar 4492 to reciprocate up and down, that is, drive the sliding column 443 to move up and down in the sleeve 442, so that the exhaust plate 43 is continuously rotated between the first position and the second position, thereby achieving the effect of continuously transforming the exhaust angle, which can further increase the exhaust range, thereby improving the air purification effect and reducing the risk of infectious aerosol transmission.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
