As shown in fig. 3 to 6, the fan guard 200 includes a housing 201 with an archimedean spiral shape, the housing 201 has a circular air inlet 202 on a front end surface, a through hole 203 on a rear end surface, and a square air outlet 204 on a bottom. The hole wall of the air inlet 202 is provided with a first horizontal plane 205, a first inclined plane 206, a first vertical plane 207, a second horizontal plane 208, a second vertical plane 209 and a third horizontal plane 210 from front to back in sequence along the circumferential direction. The first inclined surface 206 is inclined gradually outward in a radial direction from front to rear, and the first vertical surface 207 and the second vertical surface 209 each extend inward in a radial direction. Thus, a tapered groove 211 formed of the first inclined surface 206 and the first vertical surface 207 and a stepped groove 212 formed of the first vertical surface 207, the second horizontal surface 208 and the second vertical surface 209 are formed in the inner wall of the intake vent.
As shown in fig. 1, 7 and 9, the fixing spring 600 is a long elastic rod with a curvature radius slightly larger than that of the tapered slot 211 and a length slightly smaller than the circumference of the tapered slot 211, and is preferably made of spring steel. The strainer 500 has a circular shape with a diameter substantially the same as that of the tapered recess 211. The wind-collecting ring 400 includes a fixing ring 401 and a tapered ring 402 extending axially rearward from an inner ring of the fixing ring 401, and the tapered ring 402 has a flared shape gradually decreasing from front to rear. The outer diameter of the fixing ring 401 is identical to that of the stepped groove 212; the thickness is slightly greater than the width of the stepped groove 212.
The wind-collecting ring 400 is installed in the stepped groove 212, the filter 500 is installed in the tapered groove 211 and abuts against the fixing ring 401 of the wind-collecting ring 400, and the fixing spring 600 is inserted into the tapered groove 211 after being compressed and deformed and abuts against the front end surface of the filter 500.
Since the bottom surface of the tapered groove 211, i.e., the first inclined surface 206, is inclined outward in the radial direction from front to rear as shown in fig. 6, the fixing spring 600 is compressed to generate an outwardly expanded tensile force F when it is caught1Acting on the first inclined surface 206 to generate a reaction force F2The reaction force is resolved into an upward force F2YAnd a rearward force F against the front face of the screen 5002XBy an action force F2XThe filter screen 500 and the wind collecting ring 400 can be firmly fixed in the fan guard 200 by uniformly applying force in the circumferential direction, and shaking and vibration cannot occur during operation.
As shown in fig. 3, a screw hole 213 is further formed around the through hole 203, and the fan guard 200 is fastened to the motor 100 by a bolt which passes through the screw hole and the seal ring 101 in order and is fastened to the front end surface of the motor. The motor shaft of the motor 100 penetrates into the fan guard 200 and is fixedly connected with the shaft hole of the impeller 300 through the flat key 102.
As shown in fig. 2, a washer 301 is provided at the front end of the impeller 300, and a bolt is passed through the washer 301 and the impeller 300 and tightened to the front end surface of the motor shaft, thereby making the connection of the impeller 300 more secure.
The cover gasket 701 and the cover 700 are both located at the front end of the fan guard 200, and bolts sequentially penetrate through the cover 700 and the cover gasket 701 to fix the cover 700 and the cover on the front end surface of the fan guard 200, so that the cover 700 can cover the air inlet. The top surface, the side surface and the front end surface of the cover cap 700 are closed, and the bottom of the cover cap is provided with an opening for air inlet, so that the effects of shielding wind and rain can be achieved.
As shown in fig. 3 and 8, the edge of the air outlet 204 has a square fan seat plate 214 extending outward in the radial direction, and both sides of one end of the fan seat plate 214, which is spaced from the fan guard 200 by a small distance, are provided with mounting grooves 216; and mounting holes 215 are formed in two sides of one end, which has a larger distance with the fan cover. The fan mount plate 214 is secured to the fan mount pad 217 by bolts passing through mounting holes 215 and mounting slots 216.
Since the fan guard 200 has an archimedes spiral shape, a small space between one side of the fan base plate 214 and the fan guard 200 makes it difficult to install the bolts, and the bolts can be laterally inserted through the open type installation grooves 216, thereby facilitating installation.
Synthesize above, the utility model discloses a main improvement point lies in: the filter screen 500 and the wind collecting ring 400 are fixed through the matching structure of the conical groove 211 and the fixing spring 600, so that the stress of the filter screen 500 and the wind collecting ring 400 is more uniform, and the vibration and abnormal sound are not easy to generate during operation; the fan cover 200 with the Archimedes spiral outline is adopted, so that the pneumatic resistance is reduced, and the airflow can be guided out more smoothly; the problem that bolts are difficult to put into due to the shape change of the fan cover 200 is solved by adopting the mounting grooves instead of the mounting holes, so that the mounting is more convenient. Compared with the existing product, the product is further optimized, and a certain positive effect is achieved.
However, those skilled in the art should realize that the above embodiments are only for illustrative purposes and are not to be used as limitations of the present invention, and that changes and modifications to the above embodiments are intended to fall within the scope of the appended claims, as long as they fall within the true spirit of the present invention.
