[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] See also Figure 1-3 As shown, the present invention provides an air purification and disinfection device, which includes a box body 10, an air inlet end 11, an air outlet end 12, a fan 21 and a purification component. The air inlet end 11 and the air outlet end 12 are respectively arranged at two ends of the box body 10, and flanges are respectively arranged at the air inlet end 11 and the air outlet end 12 for connecting pipelines to complete the air flow delivery.

[0022] The purification component is arranged inside the housing 10, and the fan 21 is arranged near the air inlet end 11. The fan 21 introduces the airflow into the housing 10 through the air inlet end 11 and discharges it outward from the air outlet end 12. The fan 21 is an axial flow type. When the fan 21 is running, it can guide the airflow from the air inlet end 11 into the housing 10, and then be transported from the air outlet end 12 after being processed by the purification component.

[0023] The purification component includes a purification filter 31 and an ultraviolet lamp 32, which are arranged at intervals along the direction from the air inlet end 11 to the air outlet end 12. The purification filter 31 can be a HEPA filter or a dust removal filter, and the airflow is filtered and dusted when passing through the purification filter 31.

[0024] The ultraviolet lamp 32 is used to emit ultraviolet light to achieve the disinfection of the airflow. The ultraviolet lamp 32 is controlled and driven by the controller 50. The ultraviolet lamp 32 has two working power levels, namely the lowest power and the highest power, and the controller 50 drives its working power.

[0025] The wind plate includes an upper rotating plate 41 and a lower rotating plate 42, which are respectively rotatably connected to the two sides of the air inlet end 11, and are jointly surrounded by the upper rotating plate 41 and the lower rotating plate 42 to form a space for limiting air flow. Specifically, the upper rotating plate 41 and the lower rotating plate 42 are respectively driven by independent motors to achieve rotation adjustment of the positions of the upper rotating plate 41 and the lower rotating plate 42.

[0026] The upper rotating plate 41 and the lower rotating plate 42 are arranged close to one side of the air inlet end 11 and are located at the upper and lower parts of the fan 21 respectively. The upper rotating plate 41 and the lower rotating plate 42 jointly guide the airflow delivered by the fan 21 .

[0027] The controller 50 is configured to adjust the rotation angles of the upper rotating plate 41 and the lower rotating plate 42 and the working power of the ultraviolet lamp 32 according to the current rotation speed of the fan 21. The specific control actions are as follows:

[0028] The fan 21 has a first rotation speed, a second rotation speed and a third rotation speed, the second rotation speed is greater than the first rotation speed, and the third rotation speed is greater than the second rotation speed.

[0029] The controller 50 is configured to drive the upper rotating plate 41 and the lower rotating plate 42 to rotate to a position where the angle between the upper rotating plate 41 and the lower rotating plate 42 is 30°-60° when the current speed value is the first speed, and control the working power of the ultraviolet lamp 32 to be the lowest power. Under the current working condition, the fan 21 guides and transports the airflow at a low speed. At this time, the upper rotating plate 41 and the lower rotating plate 42 are driven to open at a smaller opening angle so that the airflow is transported in the middle area, so that the airflow is purified through the purification filter 31 and the ultraviolet lamp 32, and the ultraviolet lamp is controlled to operate at the lowest power, which can meet the sterilization requirements under the current low air volume and reduce energy consumption.

[0030] The controller 50 is configured to drive the upper rotating plate 41 and the lower rotating plate 42 to rotate to a position where the angle between the upper rotating plate 41 and the lower rotating plate 42 is 60°-120° when the current speed value is the second speed, and control the working power of the ultraviolet lamp 32 to be the lowest power. Under the current working condition, the fan 21 guides and transports the airflow at a mid-range speed. At this time, the upper rotating plate 41 and the lower rotating plate 42 are driven to open at an increased opening angle to increase the internal flow range of the airflow, so that the airflow is purified through the purification filter 31 and the ultraviolet lamp 32, and the ultraviolet lamp is controlled to operate at the lowest power, which can meet the sterilization requirements under the current mid-range air volume and reduce energy consumption.

[0031] The controller 50 is configured to drive the upper rotating plate 41 and the lower rotating plate 42 to rotate to a position where the angle between the upper rotating plate 41 and the lower rotating plate 42 is 120°-150° when the current speed value is the third speed, and control the working power of the ultraviolet lamp 32 to be the highest power. As a result, the fan 21 delivers the maximum airflow to the inside at the highest speed, controls the opening angle of the upper rotating plate 41 and the lower rotating plate 42 to the maximum, and maximizes the delivery range of the airflow inside the box to meet the purification treatment requirements for the atmospheric flow.

[0032] The controller 50 is configured to drive the lower rotating plate 42 to swing within its limit rotation range within the first preset time period after the current speed value switches from the first speed to the second speed. That is to say, within the first preset time period, the lower rotating plate 42 is driven to swing so that the airflow is diffused and fully flows to the purification filter to achieve filtration. After the first preset time period, the position of the lower rotating plate 42 is fixed to a position of 60°-120° with the upper rotating plate 41 to achieve the diffusion effect on the airflow. Before the upper rotating plate 41 and the lower rotating plate 42 are fixed to the opening position, it corresponds to the process in which the fan 21 switches from the first speed to the second speed, and its air volume will not rise suddenly. In this stage, the lower rotating plate 42 is controlled to swing to increase the flow of the airflow inside the box body and achieve the stirring effect of the airflow. Thus, within a specific time period, the lower rotating plate 42 is swung to achieve the diffusion and stirring effect of the airflow, thereby improving the purification treatment efficiency. Optionally, the first preset time period is 10-20s.

[0033] The controller 50 is configured to drive the lower rotating plate 42 to swing within its limit rotation range within a second preset time period after the current rotation speed value switches from the second rotation speed to the third rotation speed, and the second preset time period is greater than the first preset time period. Optionally, the second preset time period is 30-40s. When the air flow rate increases with the increase in the speed of the fan, the lower rotating plate 42 is controlled to swing for a longer time, which can improve the stirring effect for a larger air flow rate.

[0034] The upper rotating plate 41 and the lower rotating plate 42 are arranged symmetrically. The limit rotation range of the lower rotating plate 42 is 0°-80°. The length dimension of the lower rotating plate 42 is greater than the length dimension of the upper rotating plate 41. In the time period when the first speed is switched to the second speed or the second speed is switched to the third speed, the lower rotating plate 42 is used to stir and push the airflow inside the box body. The length dimension of the lower rotating plate 42 is set to be greater than the length dimension of the upper rotating plate 41 to achieve better stirring and mixing effects and improve the purification treatment efficiency.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
