Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.
The embodiment of the method is that at present, a fan air inlet filter screen is mature in cleaning mode, but electric devices such as a motor are usually used for cleaning (such as a brush is driven by the motor to frequently clean a screen surface) and when the filter screen is blocked and is in a fan working state, a certain difficulty is actually brought to the cleaning process, for example, the working of the fan can be influenced when the fan is stopped for cleaning, dust can be lifted near the filter screen when the fan is not stopped for cleaning, and the filter screen is covered again along with the introduction of airflow (namely, the blockage always exists), so that the following improvement is made by I.
Referring to fig. 1-11, the invention provides a parallel centrifugal fan, which comprises a fan body 1, an air inlet pipe 101 communicated with an inlet of the fan body 1, wherein the length of the air inlet pipe 101 in the drawing is only schematic, and different lengths can be set for actual use requirements, and the air inlet is arranged at the upper part of one side of the air inlet pipe 101;
The filter ball 201 is integrally spherical, and is formed by a spherical framework and a filter screen wrapped outside the spherical framework, wherein the spherical framework is used for supporting the filter screen, the mesh number of the filter screen can be set according to the requirement, the filter screen is mainly used for reducing dust and impurities from entering the fan body 1, the filter ball 201 is rotatably arranged in the annular frame 2 through a rotating rod 202, the side surface of the filter ball 201 is always attached to the inner annular surface of the annular frame 2, so that air can be separated from dust and impurities in the air only through a filter hole on the surface of the filter ball 201, the annular brush 203 is concentrically arranged with the annular frame 2 and rotatably arranged on one side of the annular frame 2 adjacent to an air inlet of the air inlet pipe 101, the edge of one side of the annular brush 203, which is far away from the annular frame 2, is always attached to the surface of the filter ball 201, and a plurality of bristles (not shown in the figure) which are attached to the surface of the filter ball 201 are radially and circumferentially distributed on the edge of the side of the annular brush 203, which is far away from the annular frame 2;
Through the arrangement of the filtering ball 201, as shown in fig. 2, on one hand, the spherical convex surface of the filtering ball 201 between the annular frame 2 and the inlet of the air inlet pipe 101 can increase the area for filtering air, ensure the filtering effect of dust impurities in the air and the speed of the air entering the fan body 1 (compared with the existing plane filter screen, the number of the filter holes becomes larger), and on the other hand, as shown in fig. 2 and 6, the dust impurities filtered by the filtering ball 201 can move along the arc-shaped surface of the filtering ball 201 towards the direction of the annular brush plate 203 and temporarily store at the junction of the annular brush plate 203 and the filtering ball 201, thereby ensuring the cleanness of the other surfaces of the filtering ball 201 in a temporary storage mode and improving the efficiency of the air led into the fan body 1 from the air inlet pipe 101.
As shown in fig. 3, the rotating plate 204 is integrally located inside the filter ball 201, and the rotating plate 204 is provided with a plurality of rotating plates and is circumferentially and equidistantly distributed on the side surface of the rotating rod 202, because the rotating plate 204 is located inside the air inlet pipe 101, the rotating plate 204, the rotating rod 202 and the filter ball 201 are driven to rotate anticlockwise by the flow of the air along with the continuous introduction of the air flow from the air inlet at the upper part of the air inlet pipe 101, and it is worth noting that the rotating speed of the rotating rod 202 can be controlled by damping, and the rotating speed of the rotating rod 202, that is, the rotating speed of the filter ball 201, can be adjusted according to actual needs, which is a known technology and will not be repeated.
When the air filter is in operation, as shown in fig. 1,2 and 4, firstly, the fan body 1 acts to suck external air through the air inlet pipe 101, and the air flow is filtered through the filter ball 201 in advance, so that the air filtering effect is realized, dust and impurities are reduced from entering the inside of the fan body 1, and the service life of internal components of the fan body 1 is prolonged;
the spherical convex surface of the filter ball 201 between the annular frame 2 and the inlet of the air inlet pipe 101 can increase the filtering area of the filter ball 201 on air, ensure the filtering effect of dust impurities in the air and the speed of the air entering the fan body 1, and ensure that the dust impurities filtered by the filter ball 201 can move along the arc-shaped surface of the filter ball 201 and are temporarily stored at the junction of the annular brush plate 203 and the filter ball 201, thereby ensuring the cleanness of the other surfaces of the filter ball 201 in a temporary storage mode and improving the efficiency of the air led into the fan body 1 from the air inlet pipe 101;
Meanwhile, as shown in fig. 3 and 6, air continuously enters and pushes the rotating plate 204 to rotate, the rotating plate 204 drives the rotating rod 202 and the filter ball 201 to rotate, and as the annular frame 2 and the annular brush plate 203 are attached to the surface of the filter ball 201, the annular brush plate 203 can wipe the surface of the filter ball 201 in the rotating process, so that dust impurities with strong adhesiveness (such as particles, dust, greasy dirt, fibers and the like trapped by the filter ball 201 and left on the surface of the filter ball 201) are cleaned, the cleaned dust impurities temporarily exist at the junction of the filter ball 201 and the annular brush plate 203, so that the other surfaces of the filter ball 201 except the junction are relatively clean, and the efficiency of the filter ball 201 on air filtration and the air inflow are further improved;
In summary, due to the cooperation of the filter ball 201, the rotating plate 204 and the annular brush plate 203, when the fan body 1 acts, dust impurities in air can be automatically filtered, and the surface of the filter ball 201 can be automatically cleaned, so that the dust impurities can only temporarily exist in a designated interval (near the junction of the filter ball 201 and the annular brush plate 203), the cleanness of the rest surfaces of the filter ball 201 is ensured, the air filtering efficiency and the air inlet amount are ensured through the clean surfaces of the filter ball 201, the frequency of shutdown cleaning is reduced, and the operation and maintenance cost is reduced.
