Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.
The utility model discloses an air purifier, including casing and empty the straining. The casing is provided with an air inlet and an air outlet 13, the air filter is arranged in the casing, and the casing comprises a flow guide assembly arranged at the air outlet 13. The air enters the air filter through the air inlet to be purified, and then is discharged from the air outlet 13 through the flow guide assembly.
As shown in fig. 1, the guide assembly includes a guide structure 1, a centrifugal fan 2 and an air filter support 3. Referring to fig. 2, in order to correspond to the air inlet and outlet direction of the centrifugal fan 2, the flow guide structure 1 adopts an air path structure for circumferential air inlet and lateral air outlet. The inner cavity of the flow guide structure 1 forms an exhaust cavity, the upper end of the flow guide structure is provided with a mounting port 11, the mounting port 11 is communicated with the exhaust cavity, so that the shell 21 of the centrifugal fan 2 is fixed at the upper end of the flow guide structure 1 through a connecting support, and the impeller 22 of the centrifugal fan 2 is inserted from the mounting port 11 and sleeved in the exhaust cavity. An air inlet 12 is formed at the lower end of the flow guide structure 1, a plurality of circles of air outlets 13 arrayed along the circumference are formed on the side wall, and each air outlet 13 is arranged along the absolute speed direction of the gas discharged by the impeller 22. Thus, by the rotation of the centrifugal fan 2, the air flowing out of the air filter enters the diversion structure 1 from the air inlet 12, and is discharged from the air outlet 13 by the centrifugal force through the rotation of the impeller 22 in the air exhaust cavity.
In addition, to prevent the air from blowing out directly to the user, a diversion inclined plane 17 is formed on the upper and lower side walls of each air outlet 13. The guide slope 17 is a horizontal end on the side close to the impeller 22 and an inclined end on the side far from the impeller 22. The flow directing ramp 17 extends along a smooth arc from a horizontal end to a sloped end. The included angle between the inclined end and the horizontal plane is more than 0 degree and less than or equal to 80 degrees, so that the wind direction of the outlet wind is changed to be upward, the comfort degree of wind sensation is improved, and the wind loss is reduced in the process of changing the wind direction. For ease of industrial manufacture, the angle between the inclined end and the horizontal is typically 45 °.
In order to realize the structure of the air outlet 13, the flow guiding structure 1 is a cylindrical support, and comprises a flow guiding plate 14 and a guide vane 15, wherein the flow guiding plate 14 is arranged layer by layer, the guide vane 15 which is vertically arranged is connected with two adjacent layers of flow guiding plates 14, and the air outlet 13 is enclosed by the flow guiding plate 14 and the guide vane 15. As shown in fig. 3, in order to meet the structure of the air outlet 13, each guide vane 15 is disposed along the absolute velocity direction of the gas discharged from the impeller 22, so that the opposite surfaces of the adjacent guide vanes 15 serve as left and right sidewalls of the air outlet 13. And each layer of guide plate 14 is gradually raised upwards from the inner edge, so that the two adjacent layers of guide plates 14, the outer wall of the upper side guide plate 14 and the inner wall of the lower side guide plate 14 are used as the upper side wall and the lower side wall of the air outlet 13.
An annular groove 16 surrounding the air inlet 12 is formed on the inner wall of the flow guide structure 1 at the air inlet 12, and the annular groove 16 is used for inserting the lower end edge of the shell 21 of the centrifugal fan 2, so that the air inlet amount is ensured. And the air filter support 3 is fixedly connected to the air inlet 12 at the lower end of the flow guide structure 1 through a screw and is used for fixing the air filter at the upstream.
Like this, 360 mode of flowing out of circumferencial direction, the amount of wind air-out is even, and the wind sensation and the wind noise under the air volume are more comfortable, and the area of the radiation area of export than former air purifier structure has huge promotion, can effectual improvement indoor air circulation speed.
