Description

Technical Field

[0001] This invention relates to an air disinfection device and an air supply device, and particularly to an air disinfection device that uses ultraviolet light for sterilization and can be used in an air supply device, as well as an air supply device that applies the air disinfection device. Background Technology

[0002] like Figure 1 As shown, a device with air disinfection and sterilization function generally includes a housing 50, an air inlet 141, an air outlet 142, and an ultraviolet lamp 165 installed in the housing. After the air enters the housing 50 through the air inlet 141, it is irradiated by the ultraviolet lamp 165 and then blown out through the air outlet 142, thereby sterilizing and disinfecting the air.

[0003] like Figure 1 As shown, the sterilization and disinfection effect of a typical UV lamp (165) depends on its radiation dose, which is directly proportional to its radiation intensity and radiation time. However, the radiation intensity of a UV lamp (165) decreases from the center of the lamp tube (the source of ultraviolet light) outwards; that is, the closer to the center of the UV lamp (165), the stronger the radiation intensity. Therefore, the air further away from the center of the UV lamp (165) may receive insufficient radiation, and with a constant radiation time, the radiation dose received may be insufficient, potentially causing the air to be blown into the room before it has been adequately sterilized and disinfected.

[0004] Furthermore, since the ultraviolet lamp 165 is positioned parallel to the plane of the air inlet 141 or the air outlet 142, when the wind speed is high, the air quickly passes through the radiation area of ​​the ultraviolet lamp 165 and is then blown out from the air outlet 142. Due to the high wind speed, the air stays within the radiation area of ​​the ultraviolet lamp 165 for a shorter time, resulting in a shorter radiation duration. With a constant radiation intensity, the faster the wind speed, the smaller the radiation dose received by the air, and the worse the sterilization and disinfection effect.

[0005] To prolong the time air remains in the radiation zone and thus the duration of radiation exposure, wind speed is typically reduced. However, reducing wind speed may result in insufficient airflow.

[0006] Therefore, there is a need for an air disinfection and sterilization device that can improve the efficiency of air sterilization and disinfection while ensuring the air supply volume. Summary of the Invention

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Furthermore, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] The terms “first,” “second,” and “third” used in this article are for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] The following is for reference Figures 1 to 7 The air disinfection device 1 according to the present invention will be described in detail.

[0041] The air disinfection device 1 includes: a housing 10, which is provided with an air inlet 101 and an air outlet 102, and the air inlet 101 and the air outlet 102 are connected to form an air passage; an air disinfection unit 16, which is located in the air passage and extends between the air inlet 101 and the air outlet 102; and a flow guiding unit 11, which is located around the air disinfection unit 16 and guides the air flowing around the air disinfection unit 16.

[0042] The basket 10 is a rectangular hollow box and forms the outline of the air disinfection device 1.

[0043] The basket 10 includes an air inlet 101 formed by an opening allowing air to enter the basket 10, and an air outlet 102 formed by an opening allowing air from inside the basket 10 to exit the basket 10. The basket 10 includes a front panel 103 with the air inlet 101, a rear panel 104 opposite the front panel 103 and with the air outlet 102, and a plurality of side panels connecting the outer peripheral edges of the front panel 103 and the outer peripheral edges of the rear panel 104. The front panel 103 and the rear panel 104 are quadrilaterals of the same shape. The front panel 103 has a first side, a second side opposite to the first side, a third side connecting the first side and the second side, and a fourth side opposite to the third side. Similarly, the rear panel 104 has a first side, a second side opposite to the first side, a third side connecting the first side and the second side, and a fourth side opposite to the third side. The multiple side panels include a first side panel 105 connecting the first side of the front panel 103 and the first side of the rear panel 104, a second side panel 106 connecting the second side of the front panel 103 and the second side of the rear panel 104, a third side panel 140 connecting the third side of the front panel 103 and the third side of the rear panel 104, and a fourth side panel 130 connecting the fourth side of the front panel 103 and the fourth side of the rear panel 104. The first side panel 105 is opposite to the second side panel 106, and the third side panel 140 is opposite to the fourth side panel 130. The structure of the housing 10 of the present invention is not limited thereto and can be adjusted and modified according to needs and design.

[0044] Air enters the basket 10 from the air inlet 101 and is then blown out of the basket 10 from the air outlet 102, thus forming an air path connecting the air inlet 101 and the air outlet 102.

[0045] For ease of explanation, this instruction manual specifies that when the air sterilization device 1 is in use, the first side 105 and the second side 106 are placed perpendicular to the horizontal plane, and the third side 140 and the fourth side 130 are placed parallel to the horizontal plane. "In use" refers to the air sterilization device 1 being in a state where it is functioning normally and can be used. However, the placement of the air sterilization device 1 can also be changed according to usage requirements.

[0046] The air disinfection unit 16 includes an ultraviolet (UV) generator unit 22. The UV generator unit 22 generates UV light and irradiates it outwards, irradiating substances such as air within its radiation range to kill bacteria. The UV light generated by the UV generator unit 22 in this invention is short-wave ultraviolet (UV-C). The UV generator unit 22 includes a U-shaped UV lamp tube disposed in the housing 10, extending from the air inlet 101 side to the air outlet 102 side. That is, the UV lamp tube is arranged longitudinally from the air inlet 101 side to the air outlet 102 side, and its extension line intersects the plane containing the front panel 103 and the rear panel 104. However, the air disinfection unit 16 in this invention includes, but is not limited to, other means with equivalent effectiveness to UV light. The following description uses the air disinfection unit 16 including the UV generator unit 22 as an example.

[0047] In this embodiment, the ultraviolet generating unit 22 can form an ultraviolet disinfection lamp. The ultraviolet generating unit 22 extends perpendicular to the front panel 103 and parallel to the first side 105 and the second side 106. The front end of the ultraviolet generating unit 22 is located on the side of the air inlet 101.

[0048] The airflow guiding unit 11 is a baffle used to guide the air entering the housing 10, and is located around the ultraviolet generating unit 22. "Around the periphery" means that the airflow guiding unit 11 is located on the periphery of the ultraviolet generating unit 22 facing the side panel of the housing 10, that is, not on the two ends of the ultraviolet generating unit 22 near the air inlet 101 and the air outlet 102. In this embodiment, the airflow guiding unit 11 is located on opposite sides of the ultraviolet generating unit 22 (including but not limited to opposite upper and lower sides, left and right sides, etc.), or it can be located on the entire outer periphery of the ultraviolet generating unit 22, for example, forming a circular cross-section when viewed from the air inlet to the air outlet.

[0049] The flow guiding unit 11 includes an inclined portion 17, a curved portion 20, and a flow outlet 21. The flow guiding unit 11 located on one side of the ultraviolet generating unit 22 (one of the sides near the first side 105 and the second side 106 in the figure) will be described below as an example.

[0050] like Figures 3 to 5As shown, the inclined portion 17 is a sheet-like structure that slopes from the outer periphery of the ultraviolet generating unit 22 toward the center of the ultraviolet generating unit 22 and toward the air inlet 101. The inclined portion 17 includes a proximal end 170 near the ultraviolet generating unit 22, a distal end 169 further away from the ultraviolet generating unit 22 than the proximal end 170, a proximal edge 172 formed at the edge of the proximal end 170, a distal edge 171 formed at the edge of the distal end 169, a top edge 173 connecting the proximal edge 172 and the distal edge 171 and forming the outer periphery of the inclined portion, and a bottom edge 174. The extension lines of the proximal edge 172 and the distal edge 171 intersect the third side surface 140 and the fourth side surface 130 of the housing 10, wherein the top edge 173 is closer to the third side surface 140 of the housing 10 than the bottom edge 174. In this embodiment, the near side 172 and the far side 171 of the inclined portion are perpendicular to the third side surface 140 and the fourth side surface 130 of the basket body 10, and the top side 173 and the bottom side 174 of the inclined portion are parallel to the third side surface 140 and the fourth side surface 130. Furthermore, the top side 173 of the inclined portion is connected to the third side surface 140 of the basket body 10, and the bottom side 174 of the inclined portion is connected to the fourth side surface 130 of the basket body 10. (See image below) Figure 3 and Figure 4 As shown, the inclined portion 17 is inclined from either the first side surface 105 or the second side surface 106 toward the ultraviolet generating unit 22 and the air inlet 101. The straight line perpendicular to the side panel (first side surface 105 or second side surface 106) of the housing 10 at the intersection of the extended line Le from the near end 170 to the far end 169 of the inclined portion 17 and the line Le from the near end 170 to the far end 169 of the inclined portion 17 is called the vertical line Lv. The angle α formed between the vertical line Lv and the extended line Le from the near end 170 to the far end 169 of the inclined portion 17 is in the range of 10° ≤ α ≤ 30°.

[0051] The proximal end 170 of the inclined portion 17 is spaced apart from the ultraviolet generating unit 22. The spaced apart refers to the straight-line distance between the proximal end 170 of the inclined portion 17 and the outer peripheral edge of the ultraviolet generating unit 22.

[0052] The airflow guiding unit 11 includes at least two inclined portions 17. Multiple inclined portions 17 are arranged side-by-side from the air inlet 101 to the air outlet 102. The closer to the air inlet 101, the greater the distance between the proximal end 170 of the inclined portion 17 and the ultraviolet generating unit 22. "The closer to the air inlet 101, the greater the distance" means that among the multiple inclined portions 17, the smaller the distance between the inclined portion 17 and the air inlet 101, the greater the distance between the proximal end 170 of that inclined portion 17 and the ultraviolet generating unit 22. The distance between the inclined portion 17 and the air inlet 101 refers to the straight-line distance between the proximal end 170 of the inclined portion 17 and the air inlet 101.

[0053] like Figure 4 As shown, in this embodiment, the airflow guiding unit 11 located around the ultraviolet generating unit 22 includes three inclined portions 17, namely a first inclined portion 12, a second inclined portion 13, and a third inclined portion 14. The first inclined portion 12, the second inclined portion 13, and the third inclined portion 14 are arranged side-by-side sequentially from the air inlet 101 side to the air outlet 102 side. The distance between the first inclined portion 12 and the air inlet 101 is L1, the distance between the second inclined portion 13 and the air inlet 101 is L2, and the distance between the third inclined portion 14 and the air inlet 101 is L3. The distance between the proximal end 170 of the first inclined portion 12 and the ultraviolet generating unit 22 is W1, the distance between the proximal end 170 of the second inclined portion 13 and the ultraviolet generating unit 22 is W2, and the distance between the proximal end 170 of the third inclined portion 14 and the ultraviolet generating unit 22 is W3. As mentioned above, L1 < L2 < L3, and W1 > W2 > W3.

[0054] For ease of explanation, the space formed between the first inclined portion 12 and the ultraviolet generating unit 22 will be referred to as the first ventilation space, the space formed between the second inclined portion 13 and the ultraviolet generating unit 22 will be referred to as the second ventilation space, and the space formed between the third inclined portion 14 and the ultraviolet generating unit 22 will be referred to as the third ventilation space. The width of the first ventilation space is greater than the width of the second ventilation space, and the width of the second ventilation space is greater than the width of the third ventilation space.

[0055] In this embodiment, the distance between adjacent inclined portions 17 is equal. That is, the distance between the first inclined portion 12 and the second inclined portion 13 is equal to the distance between the second inclined portion 13 and the third inclined portion 14. L3-L2 = L2-L1.

[0056] The inclined portion 17 also includes a drainage port 21 formed by a notch extending from a portion of the proximal end 170 of the inclined portion to the distal end 169 of the inclined portion (e.g. Figure 5(As shown). The phrase "extending from a portion of the near end 170 of the inclined section to the far end 169 of the inclined section" means that a notch is formed from a portion of the near edge 172 of the inclined section towards the far edge 171. Viewed from the air inlet 101 towards the air outlet 102, the drainage ports 21 on adjacent inclined sections 17 are staggered. "Staggered" means that the drainage ports 21 on adjacent inclined sections 17 are partially or completely staggered, and viewed from the air inlet 101 towards the air outlet 102, the drainage ports 21 on adjacent inclined sections 17 do not completely cover each other. Since the drainage port 21 is a notch starting from a portion of the near edge of the inclined section 17, the portion retained near the edge of the inclined section 17 forms a protruding portion protruding from the drainage port 21.

[0057] In this embodiment, the drainage port 117 on the first inclined portion is located at the middle position of its proximal edge 172, the drainage port 118 on the second inclined portion adjacent to the first inclined portion 12 is located at both ends of its proximal edge 172, and the drainage port 119 on the third inclined portion adjacent to the second inclined portion 13 is located at the middle position of its proximal edge 172. The term "middle position" refers to the middle portion of the proximal edge 172 between the top edge 173 and the bottom edge 174 of the inclined portion. The term "both ends" refers to the portions of the proximal edge 172 that are relatively close to the top edge 173 or the bottom edge 174 of the inclined portion. Figure 6 As shown, viewed from the air inlet 101 towards the air outlet 102, the drain port 117 on the first inclined portion partially covers a portion of the drain port 118 on the second inclined portion, and the drain port 118 on the second inclined portion partially covers a portion of the drain port 119 on the third inclined portion. That is, a portion of the drain port 118 and its protruding portion on the second inclined portion can be seen through the drain port 117 on the first inclined portion. Similarly, a portion of the drain port 119 and its protruding portion on the third inclined portion can be seen through the drain port 118 on the second inclined portion.

[0058] The airflow guiding unit 11 also includes a curved portion 20. The curved portion 20 extends curvedly from the distal end 169 of each inclined portion 17 toward the air inlet 101 and has an inner curved surface centered near the air sterilization unit 16, i.e., near the ultraviolet sound-emitting unit 22. Here, the shape of the outer curved surface of the curved portion 20 is not limited; it can be set to any other shape as needed. The curved portion 20 includes a first curved portion 210 and a second curved portion 220.

[0059] The first curved portion 210 is a curved sheet structure having a curved sheet extending from the distal end 169 of the inclined portion 17 (first inclined portion 12) closest to the air inlet toward the side of the air inlet 101, with the center of the curved surface located on the side close to the air disinfection unit 16 (ultraviolet generating unit 22). The second curved portion 220 is a curved surface formed by bending and extending between the distal ends 169 of the inclined portions of two adjacent inclined portions 17, that is, bending and extending from the distal end of the inclined portion away from the air inlet to the distal end of the inclined portion closer to the air inlet. The center of the curved surface is located on the side close to the air disinfection unit 16 (ultraviolet generating unit 22), for example, between the distal ends 169 of the inclined portions of the second inclined portion 13 and the third inclined portion 14, and between the distal ends 169 of the inclined portions of the first inclined portion 12 and the second inclined portion 13. The curved surface of the first curved portion 210 includes a first curved side 201 that connects with the distal edge 171 of the inclined portion closest to the air inlet 101, and a second curved side 202 that is close to the side of the air inlet 101. With the line 120 connecting the first side 201 and the second side 202 of the curved portion as the boundary (as shown in the figure), the center of the curved surface of the first curved portion 210 is located on the side where the air sterilization unit 16 is provided. In this embodiment, the first side 201 of the curved portion of the first curved portion 210 is connected to the distal side 171 of the inclined portion of the first inclined portion 12. Similarly, the curved surface of the second curved portion 220 includes two sides that connect with the distal side 171 of the inclined portion, and with the line 120 connecting these two sides as the boundary, the center of the curved surface of the second curved portion 220 is located on the side where the air sterilization unit 16 is provided. The extension lines of the first side 201 and the second side 202 of the curved portion of the first curved portion 210, as well as the extension lines of the two sides of the second curved portion 220, intersect with the third side 140 and the fourth side 130 of the basket body 10.

[0060] Viewed from a direction parallel to the far side 171 of the inclined portion, two adjacent inclined portions 17 and the second curved portion 220 between them form a U-shape.

[0061] Thus, a flow guiding unit 11 is formed that can guide the air blown toward the air outlet 102. The flow guiding units 11 located at other relative positions of the ultraviolet generating unit 22 are described in the same manner.

[0062] The air disinfection device 1 also includes multiple air inlet guide vanes 126 and multiple air inlet shields 127 disposed on the downstream side of the air inlet 101 and between the ultraviolet generating unit 22.

[0063] like Figure 7As shown, the air inlet guide vane 126 consists of multiple sheet-like structures disposed between the plane of the air inlet 101 and the ultraviolet generating unit 22, and inclined towards the air outlet 102 and the air disinfection unit. The air inlet guide vane 126 includes an upstream end of the air inlet near the air inlet 101 and a downstream end of the air inlet away from the air inlet 101. Along the extending direction of the ultraviolet generating unit 22, the distance between the downstream end of the air inlet and the ultraviolet generating unit 22 is less than the distance between the upstream end of the air inlet on the same air inlet guide vane 126 and the ultraviolet generating unit 22.

[0064] The air inlet shield 127 comprises multiple sheet-like structures extending from one end of the air inlet guide vane 126 near the air inlet 101 (upstream end of the air inlet) towards the air inlet 101 and inclined toward the ultraviolet generating unit 22. The air inlet shield 127 includes a first air inlet shielding side 1271 connected to the upstream end of the air inlet of the air inlet guide vane 126, and a second air inlet shielding side 1272 closer to the air inlet 101 than the first air inlet shielding side 1271. The distance between the first air inlet shielding side 1271 and the ultraviolet generating unit 22 is greater than the distance between the second air inlet shielding side 1272 of the same air inlet shield 127 and the ultraviolet generating unit 22.

[0065] The air disinfection device 1 further includes a diversion unit 125, which comprises two diversion plates, such as a first diversion plate 1251 and a second diversion plate 1252, extending curvedly from the center of the air inlet 101 to both sides of the air inlet 101. The ends of the first diversion plate 1251 and the second diversion plate 1252 near the air inlet 101 are connected to each other, and the ends away from the air inlet 101 are separated from each other to form an open space toward the air disinfection unit 16 (ultraviolet generating unit 22). The first diversion plate 1251 and the second diversion plate 1252 have curved surfaces protruding toward both sides of the air inlet 101.

[0066] Looking from the third side 140 towards the fourth side 130, the interconnected air inlet guide vanes 126 and air inlet baffles 127 form a V-shape, and multiple air inlet guide vanes 126 and air inlet baffles 127 are arranged side by side to form multiple V-shaped structures. The V-shaped structures are symmetrically arranged on both sides with respect to the center extension line of the air inlet 101, with the openings of the V-shaped structures facing the center extension line of the air inlet 101. A diversion unit 125 is disposed between the openings of the V-shaped structures on both sides. The distance between the upstream ends of the air inlets of adjacent air inlet guide vanes 126 is equal, and similarly, the distance between the downstream ends of the air inlets of adjacent air inlet guide vanes 126 is equal. The distance between the second sides 1272 of the air inlet baffles 127 is equal, and similarly, the distance between the first sides 1271 of the air inlet baffles 127 is equal. The air inlet guide vane 126 is located downstream of the air inlet shield 127. The air sterilization device 1 also includes multiple air outlet guide vanes 128 and multiple air outlet shields 129 located upstream of the air outlet 102 and between the air outlet and the ultraviolet generating unit 22.

[0067] The air outlet guide vane 128 is a plurality of sheet-like structures disposed between the plane of the air outlet 102 and the air guiding unit, and inclined toward the air outlet 102 and the air disinfection unit 16. The air outlet guide vane 128 includes a downstream end of the air outlet near the air outlet 102 and an upstream end of the air outlet away from the air outlet 102. The distance between the upstream end of the air outlet and the ultraviolet generating unit 22 is greater than the distance between the downstream end of the air outlet of the same air outlet guide vane 128 and the ultraviolet generating unit 22.

[0068] The air outlet baffle 129 comprises multiple sheet-like structures extending from the air outlet guide vane 128 near the air inlet towards the air inlet side and tilting towards the air sterilization unit 16. The air outlet baffle 129 includes a first air outlet baffle side 1291 connected to the upstream end of the air outlet of the air outlet guide vane 128, and a second air outlet baffle side 1292 closer to the air inlet 101 than the first air outlet baffle side 1291. The distance between the first air outlet baffle side 1291 and the ultraviolet generating unit 22 is greater than the distance between the second air outlet baffle side 1292 and the ultraviolet generating unit 22.

[0069] Viewed from the third side 140 towards the fourth side 130, the air outlet guide vanes 128 and the air outlet baffles 129 form multiple V-shapes. The distance between the upstream ends of the air outlets of adjacent air outlet guide vanes 128 is equal, and similarly, the distance between the downstream ends of the air outlets of adjacent air outlet guide vanes 128 is equal. The distance between the second sides 1292 of the air outlet baffles 129 is equal, and similarly, the distance between the first sides 1291 of the air outlet baffles 129 is equal. The air outlet guide vanes 128 are located downstream of the air outlet baffles 129.

[0070] In this embodiment, an air supply device 18 for using the air disinfection device is also included.

[0071] In addition to the air sterilization device 1 mentioned above, the air supply device 18 also includes an air supply unit 23. In this case, the front panel 103 and side panels (including the first side panel 106, the second side panel 106, the third side panel 140 and the fourth side panel 130) of the housing 10 can be formed as part of the housing of the air supply device 18, and the rear panel 104 can be omitted or installed in the air supply device 18 as needed.

[0072] The air supply unit 23 is used to supply air from the air inlet 101 to the air outlet 102, and includes fan blades, a motor that drives the fan blades to rotate, and a snail shell that houses the fan blades. In this embodiment, the air supply unit 23 is located downstream of the ultraviolet generating unit 22, specifically, the air supply unit 23 is located downstream of the air outlet 102 of the air disinfection device.

[0073] However, the location of the air supply unit 23 is not limited to that in this embodiment. The air supply unit 23 can also be located upstream of the ultraviolet generating unit 22. Specifically, the air supply unit 23 can also be located upstream of the air inlet 101 of the air disinfection device.

[0074] In this embodiment, the air supply unit 23 is located downstream of the air outlet 102 of the air sterilization device 1, that is, outside the housing 10 of the air sterilization device 1, and connected to the air outlet 102 of the air sterilization device 1. The air sterilization device 1 and the air supply unit 23 can be separately connected or integrated. The air supply unit 23 can also be located upstream of the air outlet 102 of the air sterilization device, or downstream of the air inlet 101 of the air sterilization device, that is, the air supply unit 23 can be located inside the housing 10 of the air sterilization device.

[0075] The air supply device 18 may also include an air handling unit for processing the air, as well as functional units for other purposes. Air processing includes adjusting one or more of the air's characteristics, such as temperature, humidity, and quality. Depending on its function, the air supply device 18 may be a total heat exchange device or an air purification device, etc.

[0076] The operation mode of the air disinfection device according to the present invention will be described below.

[0077] Under the action of the air supply device 18, air enters the basket 10 from the air inlet 101 of the air disinfection device and is then blown out of the basket 10 from the air outlet 102.

[0078] First, air enters the housing 10 through the air inlet 101 and diffuses within the space formed between the side panels connecting the front panel 103 and the rear panel 104. Under the action of the flow-dividing unit 125 located downstream of the air inlet 101 and multiple air inlet baffles 127, the air is divided into multiple airflows, flowing from the space between multiple adjacent air inlet baffles 127 towards the air outlet 102. Thus, the air entering the housing 10 can be more evenly guided towards the air outlet 102.

[0079] Because the air inlet guide vane 126 is tilted towards the ultraviolet generating unit 22, the air, guided by the air inlet guide vane 126, changes from a state of diffusion to the periphery of the housing 10 to a state of concentrated blowing towards the ultraviolet generating unit 22. This allows most of the air to flow more effectively through the central radiation area of ​​the ultraviolet generating unit.

[0080] The air inlet guide vane 126 and the air inlet shield 127 form a V-shape protruding towards the outer periphery of the ultraviolet generating unit 22. Since ultraviolet radiation propagates in a straight line, ultraviolet rays passing through the space between multiple adjacent air inlet guide vanes 126 will propagate along the direction of the air inlet guide vane 126 without refraction that changes the direction of propagation. They will be blocked by the air inlet shield 127, which is inclined in the opposite direction to the air inlet guide vane 126, and thus will not propagate further towards the air inlet 101.

[0081] Therefore, this air disinfection device 1 can effectively disinfect and sterilize air by passing through the space formed between the air inlet guide plate 126 and the air inlet shield 127, while also blocking ultraviolet rays from radiating outward from the housing 10 through the air inlet 101, thereby preventing ultraviolet rays from causing harm or damage to the human body or other instruments and objects, and improving the safety of the device.

[0082] Guided by the air inlet guide vane 126, the air is blown toward the air outlet 102.

[0083] Since the ultraviolet generating unit 22 is provided with flow guiding units 11 on both sides, and the flow guiding units 11 are provided with inclined portions 17 spaced apart from the ultraviolet generating unit 22, a portion of the air entering the basket 10 can pass through the space formed between the inclined portions 17 and the ultraviolet generating unit 22. At this time, the air passing through the space between the inclined portions 17 and the ultraviolet generating unit 22 can be irradiated by the ultraviolet rays generated by the ultraviolet generating unit 22, thereby killing bacteria in the air.

[0084] However, air supplied from a location far from the ultraviolet generating unit 22 may receive less radiation intensity due to its distance from the radiation center of the ultraviolet generating unit 22, resulting in insufficient radiation dose to kill bacteria in the air.

[0085] When a portion of the air far from the radiation center of the ultraviolet generating unit 22 is blown towards the air outlet 102 at a high speed, it will collide with the first inclined portion 12. Since the first inclined portion 12 is inclined towards the air inlet 101, the air colliding with the first inclined portion 12 will be guided towards its far end 169. At this time, the air that changes direction after the collision mixes with the air entering from the air inlet 101, forming a vortex that rotates and flows towards the air inlet 101 between the first inclined portion 12 and the air inlet guide vane 126. The portion of air originally far from the radiation center of the ultraviolet generating unit 22 flows towards the radiation center area of ​​the ultraviolet generating unit 22 under the influence of the vortex. Thus, the portion of air that was previously exposed to weaker radiation can be exposed to stronger radiation again, ensuring that this portion of air also receives a sufficient radiation dose, thereby improving the overall disinfection and sterilization efficiency.

[0086] Furthermore, the air that was originally blown at high speed towards the air outlet 102 experiences a decrease in speed after impacting the inclined section 17. Guided by the inclined section 17, it forms a vortex, and its speed passing through the radiation center area of ​​the ultraviolet generating unit 22 also decreases. As a result, the time the air is exposed to ultraviolet radiation can be extended, thereby increasing the radiation dose received by the air and improving the overall disinfection and sterilization efficiency.

[0087] Furthermore, since air enters the basket 10 through the air inlet 101 and exits through the air outlet 102, the air inlet 101 side of the basket 10 is under positive pressure, while the air outlet 102 side is under negative pressure. Moreover, when the air sterilization device is operating, air continuously enters the basket 10 through the air inlet 101 and is blown towards the first inclined section 12 via the air inlet guide vane 126. Therefore, the space between the first inclined section 12 and the air inlet guide vane 126 is under positive pressure. With a continuous supply of air, when the slower-moving air in the vortex reaches the proximal end 170 of the inclined section near the first inclined section 12, it will be carried by the higher-moving air that was originally concentrated in the first ventilation space and continue to be blown towards the air outlet 102.

[0088] Therefore, the air sterilization device can increase the radiation dose of the air by utilizing eddies while ensuring that the air in the eddies can continue to be blown towards the air outlet 102. This prevents air from becoming stagnant in the air sterilization device due to the eddies, which would prevent air from being delivered.

[0089] Furthermore, the width of the second ventilation space is set to be smaller than the width of the first ventilation space. In the air supplied from the air inlet 101 to the first inclined section 12, air that does not collide with the first inclined section 12 can pass smoothly through the first ventilation space at a higher wind speed. Because the width of the second ventilation space is smaller than the width of the first ventilation space, a portion of the air that passes smoothly through the first ventilation space will interfere with the second inclined section 13. Similarly, the air that collides with the second inclined section 13 at a higher speed, guided by the second inclined section 13, flows towards the air inlet 101 side and forms vortices, thereby increasing the radiation dose of the air.

[0090] Similarly, the width of the third ventilation space is set to be smaller than the width of the second ventilation space.

[0091] In addition, the airflow guiding unit 11 is provided with a curved section. Since the curved section 20 bends from the distal end 169 of the inclined section 17 toward the air inlet 101, when the air flows along the curved surface on the curved section 20 under the guidance of the inclined section 17, the air can form vortices more smoothly, thereby suppressing the generation of turbulence and noise.

[0092] In addition, since the curved portion 20 is connected to the adjacent inclined portion 17 or is connected to the side panel of the basket 10, it can prevent air from forming turbulence in the basket 10.

[0093] Furthermore, the inclined portion 17 is provided with a drainage port 21, and the drainage ports 21 on adjacent inclined portions 17 are staggered.

[0094] When air blows from the inlet 101 towards the first inclined section 12, a portion of the air flows through the outlet 21 towards the second inclined section 13, while another portion forms a vortex under the influence of the first inclined section 12. The portion of air blown from the outlet 117 of the first inclined section 12 towards the second inclined section 13 interferes with the portion of the second inclined section 13 protruding from the outlet, thus forming a vortex. A portion of this air then flows through the outlet 118 on the second inclined section 13 towards the third inclined section 14. Similarly, this portion of air interferes with the portion of the third inclined section 14 protruding from the outlet 21, thus forming a vortex.

[0095] Therefore, the air entering from the air inlet 101 can form vortices more evenly in the spaces formed between the first inclined part 12, the second inclined part 13, and the third inclined part 14, thereby increasing the radiation dose more evenly and improving the efficiency of disinfection and sterilization.

[0096] Furthermore, when air is blown from the third ventilation space to the air outlet 102, it will diffuse towards the outer periphery of the ultraviolet generating unit 22 under the guidance of multiple air outlet shields 129. Since the air outlet guide vanes 128 are tilted towards the ultraviolet generating unit 22, that is, the air outlet guide vanes 128 are concentrated and tilted towards the air outlet 102, the air will be concentrated and delivered to the air outlet 102 under the guidance of the air outlet guide vanes 128. This allows the disinfected air to be concentrated and delivered to the air outlet 102, thereby preventing turbulence and improving air delivery efficiency, while also preventing ultraviolet rays from irradiating outwards from the air outlet 102 and causing harm or damage to people or other equipment.

[0097] Therefore, the present invention provides an air disinfection device that can improve the disinfection and sterilization efficiency of air while ensuring the air supply volume.

[0098] In summary, the present invention provides an air disinfection unit, and the air disinfection device according to the present invention is used to disinfect or sterilize air flowing through the air disinfection device. The inclined portion allows air to generate vortices within the air disinfection device, which on the one hand increases the air disinfection time, and on the other hand promotes airflow within the device to disinfect air moving away from the unit, thereby improving air sterilization efficiency while ensuring sufficient airflow.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
