[0042] In the description of the present invention, it should be noted that the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0043] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] See also Figure 1 and Figure 2In the first aspect of the embodiment, the present application provides an air supply device, including a housing 10, an air duct 20, a fan and a baffle 30. Among them, the housing 10 has a plurality of first through holes 11 on the side and a second through hole 12 on the top. The air duct 20 is assembled in the housing 10, and the air inlet ends 22 of the plurality of air ducts 20 are respectively connected to the plurality of first through holes 11, and the air outlet ends 21 are all connected to the second through holes 12. A plurality of fans are respectively assembled in the plurality of air ducts 20 and electrically connected to an external power supply. The baffle 30 is arranged at the port edge of the air outlet end 21, and is rotatably connected to the port edge of the air outlet end 21, and can open or cover the port of the air outlet end 21. When in use, the number of fans to be opened can be selected according to the actual application needs. After the fan is turned on, the baffle 30 at the port of the air outlet end 21 of the air duct 20 where the fan is located is impacted by the airflow, thereby opening the port, and the airflow flows out from the second through hole 12. At this time, the baffle 30 at the air outlet 21 port of the air duct 20 where the fan in standby state is located still covers the port, which can prevent the airflow from backflowing into the air duct 20, reducing the loss of air volume and air pressure. This solves the technical problem in the prior art that when multiple air ducts 20 are supplying air in parallel, the air flow is easily backflowed into the air duct 20 where the fan in standby state is located, resulting in loss of air volume and air pressure.

[0045] Specifically, two protrusions along the edge direction can be set at the edge of the air outlet port 21, and two connecting parts can be set at one end of the baffle 30. A pin shaft passes through the two protrusions and the two connecting parts to achieve a rotational connection between the baffle 30 and the edge of the air outlet port 21.

[0046] In some embodiments, a baffle 30 is configured for each air outlet 21 of the air duct 20. In order to prevent the baffle 30 from excessively rotating so that the baffle 30 cannot be reset when the fan is turned off, the protrusion on the edge of the port of the air outlet 21 can be extended a distance to the outside of the port, for example, by 2 cm, to prevent the baffle 30 from flipping at an angle of 90° or even exceeding 90° when impacted by the airflow. When the fan is turned off, the baffle 30 will re-close the air outlet 21 due to its self-repositioning.

[0047] See also Figure 4 In some embodiments, a partition 50 may be provided in the second through hole 12 to fix the position of the port of the air outlet 21 of each air duct 20 and facilitate the installation of the baffle 30. The edge of the partition 50 is fixedly connected to the inner wall of the second through hole 12, and a fourth through hole adapted to the shape of the port of the air outlet 21 of each air duct 20 is opened on the partition 50, and the edge of the port of the air outlet 21 of each air duct 20 is fixedly connected to the edge of the fourth through hole. The baffle 30 is assembled on the partition 50. Under this structure, in order to prevent the baffle 30 from rotating excessively and causing the baffle 30 to be unable to reset when the fan is turned off, the connection between the baffle 30 and the partition 50 can be appropriately away from the port of the air outlet 21 corresponding to it, for example, 2 cm away from the edge of the port of the air outlet 21 of the air duct 20.

[0048] See also Figure 2 In some embodiments, the number of the first through hole 11 and the number of the air duct 20 are both two, the air outlet ends 21 of the two air ducts 20 are adjacent, and a baffle 30 is assembled between the two air outlet ends 21, and can be flipped between the two air outlet ends 21, covering one air outlet end 21 while opening the other air outlet end 21. When in use, when air is supplied through one air duct 20, the baffle 30 will be opened due to the impact of the airflow of the air duct 20, and will flip toward the port direction of the air outlet end 21 of the other air duct 20 due to inertia, and cover it. When air is supplied through two air ducts 20 at the same time, the baffle 30 will remain in a vertical state due to the impact of the airflow of the two air ducts 20, and stabilize between the two ports.

[0049] See also Figure 3 Furthermore, in order to prevent the baffle 30 from having an insufficient rotation angle, resulting in the baffle 30 being unable to flip to the other air outlet end 21 when air is supplied through an air duct 20, guide protrusions 32 can be provided on both sides of the baffle 30. When the airflow passes through the guide protrusions 32, pressure will be applied to the baffle 30, making it easier for the baffle 30 to flip to the other side.

[0050] See also Figure 2 In some embodiments, a rotation drive mechanism 31 is disposed at the connection between the baffle 30 and the edge of the outlet port 21. Specifically, the rotation drive mechanism 31 can be a rotary motor, which is connected to the aforementioned pin shaft to actively control the flip angle of the baffle 30.

[0051] Please refer to FIG. 7. In the embodiment of the second aspect, the utility model provides an air filtering device, including any of the aforementioned air supply devices, and a filter 40 is arranged at the second through hole 12. The filter 40 can be an activated carbon filter and / or HEPA. Specifically, an activated carbon filter and a HEPA filter that are adapted to the shape of the second through hole 12 can be used, and the edge of the activated carbon filter or the HEPA filter is fixedly connected to the edge of the port of the second through hole 12. A buckle can be set on the edge of the activated carbon filter or the HEPA filter, and a slot can be set on the edge of the port of the second through hole 12, and the fixed connection is achieved by the snap-fitting of the buckle and the slot; a groove that is adapted to the shape of the activated carbon filter or the HEPA filter can also be set on the inner wall of the second through hole 12, and the activated carbon filter or the HEPA filter can be directly inserted into the groove. After passing through the air duct 20, the airflow will continue to pass through the filter 40, and flow out of the second through hole 12 after filtering, thereby achieving the purpose of filtering the air.

[0052] In some preferred embodiments, a filter 40 may also be installed at the air inlet end 22 of the air duct 20 to further improve the air filtering effect.

[0053] In an embodiment of the third aspect, the utility model provides an air disinfection device, including any of the aforementioned air supply devices, wherein a plasma generating device is disposed in the air duct 20, and the device is electrically connected to an external power source. The plasma generating device can be used to disinfect the airflow entering the air duct 20, and then flow out through the second through hole 12.

[0054] Specifically, the blower and plasma generator in this embodiment can adopt the plasma disinfection device in the prior art, which integrates the blower and the plasma generator into one. Since the working principle of the plasma disinfection device belongs to the prior art, it will not be described here.

[0055] See also Figure 6 and Figure 7 In an embodiment of the fourth aspect, the utility model provides an air disinfection device, including any of the aforementioned air supply devices, wherein an ultraviolet lamp 60 is disposed in the second through hole 12 and is electrically connected to an external power source. Specifically, the ultraviolet lamp 60 can be fixed to the inner wall of the second through hole 12 by a fixing member, or a plurality of ultraviolet lamps 60 can be provided, respectively fixed at the ports of the air outlet ends 21 of each air duct 20, for example, assembled on the aforementioned partition 50. It is used to disinfect the airflow in the illumination area of ​​the ultraviolet lamp 60 by ultraviolet rays.

When in use, the prepared disinfectant is stored in the disinfectant storage container, the fan is turned on for air supply, and the nozzle 70 is turned on at the same time, and the nozzle 70 sprays the disinfectant toward the second through hole 12 to disinfect the airflow flowing out through the second through hole 12.

[0057] See also Figure 5 and Figure 7 In some embodiments, the disinfectant storage container can be used as a separate device and connected to the nozzle 70 when needed. Alternatively, a storage compartment 80 for placing the disinfectant storage container can be provided on the air disinfection device.

[0058] Specifically, the storage bin 80 is assembled in the side wall of the housing 10, and a third through hole is opened at the side wall of the housing 10 corresponding to the storage bin 80. The third through hole is provided with a bin door 81, and the bin door 81 is rotatably connected to the edge of the third through hole. The disinfectant storage container is placed in the storage bin 80 and connected to the nozzle 70 through a hose.

[0059] In some embodiments, the nozzle 70 is connected to the edge of the second through hole 12 via a damping hinge, and the direction of the nozzle 70 can be adjusted according to actual application needs.

[0060] In some embodiments, the nozzle 70 is an atomizing nozzle, which further improves the disinfection effect on the airflow.

When the airflow passes through the air duct 20, it passes through the plasma generator for the first level of disinfection, and when it reaches the second through hole 12, it reaches the irradiation area of ​​the ultraviolet lamp 60 for the second level of disinfection, and then passes through the activated carbon filter and the HEPA filter for filtration, and finally passes through the disinfectant sprayed by the atomizing nozzle for the third level of disinfection. Through the three-level disinfection and two-level filtration, the air flowing out through the second through hole 12 can reach the hundred-level purification level.
