DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figure 1-3 As shown, an improved centrifugal impeller according to an embodiment of the utility model comprises a centrifugal impeller body 1; a plurality of grooves 11 are formed on the side wall of the centrifugal impeller body 1; the grooves 11 are evenly distributed on the side wall of the centrifugal impeller body 1 and have the same structure; a telescopic rod 12 is fixedly connected to the side wall of the groove 11; a spring 13 is sleeved on the outer side of the telescopic rod 12; the ends of the telescopic rod 12 and the spring 13 are fixedly connected to the same protrusion 14; a fixing groove 15 is formed on the side wall of the protrusion 14; a rotating wheel 16 is rotatably connected to the side wall of the fixing groove 15; when in use, when the centrifugal impeller body 1 vibrates during operation, the protrusion 14 on one side may collide with the inner wall of the centrifugal fan, and at this time, the rotating wheel When the wheel 16 is in contact with the centrifugal fan, the impeller 16 can rotate on the inner wall of the centrifugal fan. At the same time, the telescopic rod 12 and the spring 13 can be telescopically moved by colliding with the protrusion 14. Then, under the elastic force of the spring 13, a certain reaction force can be applied to the protrusion 14 to buffer the impact force generated by the collision and reduce the generation of noise. In this process, the existing centrifugal impeller body 1 can generate a certain vibration during use, causing the centrifugal impeller body 1 to collide with the inner wall of the centrifugal fan, which is prone to generate a certain noise. At this time, through the mutual cooperation of the protrusion 14 and the spring 13, the centrifugal impeller body 1 can play a buffering role when vibrating, and the generation of noise can be reduced.
[0025] like Figure 1 , 4As shown, the side wall of the centrifugal impeller body 1 is fixedly connected with a plurality of elastic bands 2; the elastic bands 2 are evenly distributed on the side wall of the centrifugal impeller body 1 and have the same structure; the side wall of the elastic band 2 is fixedly connected with a weight ball 21; when in use, when the centrifugal impeller body 1 is not working, under the flexible action of the elastic band 2, the elastic band 2 can contact with the output shaft to block the gap between the output shaft and the centrifugal impeller body 1, so that dust and water stains from the outside do not enter the gap between the two. When the centrifugal impeller body 1 is working and rotating, under the action of centrifugal force, Under the action of gravity of the counterweight ball 21, the elastic belt 2 can be straightened, and the elastic belt 2 can prevent external dust and water stains from entering the gap on the side wall of the centrifugal impeller body 1, so that the dust and water stains can be thrown away to the surroundings. In this process, it can reduce the difficulty of protecting the centrifugal impeller body 1 when the centrifugal impeller body 1 is not in use, resulting in external water stains and dust easily entering between the centrifugal impeller body 1 and the output shaft, which is prone to corrosion over time. At this time, the elastic belt 2 is set to protect the centrifugal impeller body 1 when it is not in use.
[0026] like Figure 3 As shown, a pair of push rods 3 are hinged on the side wall of the protrusion 14; the push rods 3 are symmetrically arranged on both sides of the protrusion 14 and have the same structure; a roller 31 is fixedly connected to the end of the push rod 3; an elastic rope 32 is fixedly connected between the push rod 3 and the protrusion 14; when in use, when the protrusion 14 collides with the inner wall of the centrifugal fan, the roller 31 will first contact the inner wall of the centrifugal fan, so that it rolls on its inner wall, and the rollers 31 on both sides can be stretched open by squeezing, and the elastic rope 32 will be stretched and lengthened. At this time, under the action of the internal torsion spring at the hinge of the push rod 3 and the elastic force of the elastic rope 32, a certain reaction force can be applied to reduce the collision force. In this process, when the centrifugal impeller body 1 vibrates, the buffering effect of the spring 13 is poor, thereby causing some noise to still be generated. At this time, the push rod 3 and the elastic rope 32 are set to further increase the protective buffering effect of the centrifugal impeller body 1 when it vibrates.
[0027] like Figure 2 , 5As shown, the side wall of the centrifugal impeller body 1 is fixedly connected with a plurality of elastic plates 4; the elastic plates 4 are evenly distributed on the side wall of the centrifugal impeller body 1 and have the same structure; the side wall of the elastic plate 4 is fixedly connected with a cleaning cotton 41; when in use, when the output shaft is inserted into the middle of the centrifugal impeller body 1, the output shaft will contact and squeeze the surrounding elastic plates 4, and the elastic plates 4 can be squeezed to produce a certain deformation. At this time, under the elastic force of the surrounding elastic plates 4, a certain reaction force can be applied to the output shaft to push the output shaft toward the middle of the centrifugal impeller body 1, and at the same time, the output shaft will also slide toward the middle of the surrounding elastic plates 4, so that the output shaft is easy to insert into the centrifugal impeller body 1, and at the same time, during the process of inserting the output shaft, under the elastic force of the elastic plate 4, the cleaning cotton 41 can be fully in contact with the surface of the output shaft, and the dust and impurities attached to the surface of the output shaft can be wiped off by the cleaning cotton 41, so that it can be fully in contact with the centrifugal impeller body 1. In this process, the output shaft can be inserted into the middle part of the centrifugal impeller body 1, which makes it difficult to align the two, resulting in a more complicated insertion process. At this time, the elastic plate 4 is set to play a limiting role when the output shaft is inserted into the middle part of the centrifugal impeller body 1, and at the same time, the cleaning cotton 41 can play a role in cleaning the dust and impurities attached to the surface of the output shaft.
[0028] like Figure 3 As shown, a pair of brackets 5 are fixedly connected to the side walls of the protrusion 14; the brackets 5 are symmetrically arranged on both sides of the protrusion 14 and have the same structure; a plurality of cleaning brushes 51 are evenly fixedly connected to the side walls of the brackets 5; during use, when the protrusion 14 is squeezed and approaches the side wall of the centrifugal impeller body 1, the bracket 5 moves synchronously with the protrusion 14, and at this time, the side wall of the groove 11 can be cleaned by the cleaning brush 51 to sweep away the dust attached to the side wall of the groove 11. In this process, the centrifugal impeller body 1 can be reduced to accumulate more dust in the groove 11 after long-term use, which is inconvenient to clean. Over time, the centrifugal impeller body 1 is easily corroded. At this time, the cleaning brush 51 is provided to clean the dust attached to the side wall of the groove 11.
[0029] like Figure 3 As shown, the side wall of the cleaning brush 51 is fixedly connected with a connecting rod 6; the connecting rod 6 passes through the wall of the cleaning brush 51 and is fixedly connected thereto; when in use, when the cleaning brush 51 is cleaning, multiple cleaning brushes 51 can be fixedly connected by the connecting rod 6 so that they are concentrated together when cleaning. In this process, the cleaning brush 51 can be reduced to be relatively scattered when cleaning, resulting in poor cleaning effect of the cleaning brush 51 on the side wall of the groove 11, thereby causing a certain impact on the use effect of the cleaning brush 51. At this time, the connecting rod 6 is set to concentrate the cleaning brush 51 when cleaning, thereby improving the cleaning effect.
[0030] like Figure 4 As shown, the side wall of the elastic band 2 is evenly fixed with a plurality of elastic strips 7; when in use, the elastic band 2 can be fixedly connected as a whole by laying a plurality of elastic strips 7 on the side wall of the elastic band 2. In this process, the problem of the elastic band 2 being easily torn and damaged after long-term use can be reduced, which makes it difficult for the elastic band 2 to play a good protective role and affects the use effect of the elastic band 2. At this time, the elastic strips 7 are set to fix the wall of the elastic band 2 and increase the service life of the elastic band 2.
[0031] During operation, when the centrifugal impeller body 1 vibrates during operation, the protrusion 14 on one side may collide with the inner wall of the centrifugal fan. At this time, the contact between the impeller 16 and the centrifugal fan may cause the impeller 16 to rotate on the inner wall of the centrifugal fan. At the same time, the collision with the protrusion 14 may cause the telescopic rod 12 and the spring 13 to perform telescopic movement. Then, under the elastic force of the spring 13, a certain reaction force may be applied to the protrusion 14 to buffer the impact force generated by the collision and reduce the noise. During use, when the centrifugal impeller body 1 is not working, under the flexible action of the elastic belt 2, the elastic belt 2 may contact with the output shaft to block the gap between the output shaft and the centrifugal impeller body 1, so that Dust and water stains from the outside do not enter the gap between the two. When the centrifugal impeller body 1 is working and rotating, under the action of centrifugal force and the gravity of the counterweight ball 21, the elastic band 2 can be straightened, and the elastic band 2 can prevent dust and water stains from the outside from entering the gap on the side wall of the centrifugal impeller body 1, so that the dust and water stains can be thrown away to the surroundings. When in use, when the protrusion 14 collides with the inner wall of the centrifugal fan, the roller 31 will first contact the inner wall of the centrifugal fan, so that it rolls on its inner wall, and the rollers 31 on both sides can be stretched open by squeezing, and the elastic rope 32 will be stretched and lengthened. At this time, the internal torsion spring at the hinge of the top rod 3 and the elastic rope 32 are Under the action of force, a certain reaction force can be applied to reduce the collision force. During use, when the output shaft is inserted into the middle of the centrifugal impeller body 1, the output shaft will contact and squeeze the elastic plates 4 around it. By squeezing the elastic plates 4, it can cause a certain deformation. At this time, under the elastic force of the elastic plates 4 around it, a certain reaction force can be applied to the output shaft to push the output shaft toward the middle of the centrifugal impeller body 1. At the same time, the output shaft will also slide toward the middle of the elastic plates 4 around it, which is convenient for inserting the output shaft into the middle of the centrifugal impeller body 1. At the same time, in the process of inserting the output shaft, under the elastic force of the elastic plates 4, the cleaning cotton 41 can be fully in contact with the surface of the output shaft. The cleaning cotton 41 can wipe off the dust and impurities attached to the surface of the output shaft so that it can fully contact the centrifugal impeller body 1. When in use, when the protrusion 14 is squeezed, the protrusion 14 approaches the side wall of the centrifugal impeller body 1, and the bracket 5 moves synchronously with the protrusion 14. At this time, the side wall of the groove 11 can be cleaned by the cleaning brush 51 to sweep away the dust attached to the side wall of the groove 11. When in use, when the cleaning brush 51 is cleaning, multiple cleaning brushes 51 can be fixedly connected by the connecting rod 6 so that they are concentrated together when cleaning. When in use, multiple elastic strips 7 are laid on the side wall of the elastic belt 2 to fix the elastic belt 2 as a whole.
