Detailed Description
Example one
As shown in fig. 1-4: the multifunctional broom for cleaning comprises a brush hair mounting frame 1, a broom rod 2, a bristle tuft 3 and a lifting mechanism 4; the bristle mounting rack 1 is provided with a plurality of through holes 11 arranged side by side; the bristle cluster 3 comprises bristles 31 and a sliding block 32, the bottom of the sliding block 32 is fixedly connected with the bristles 31, and the sliding block 32 is arranged in the through hole 11; at least one side wall of the through hole 11 is a plane, and the size and the shape of the slide block 32 are matched with those of the through hole 11; the top of the through hole 11 is provided with a lifting mechanism 4, and the lifting mechanism 4 is arranged in the bristle mounting frame 1 and is connected with the sliding block 32 in a ball screw manner so as to drive the sliding block 32; the broom rod 2 is connected with the brush hair mounting rack 1 through a universal joint 21.
In the embodiment, the lifting mechanism 4 drives the sliding block 32 to move up and down in the through hole 11 in a manner of driving by the screw rod 42, so that the length of the bristles 31 of the bristle cluster 3 exposed out of the bottom of the through hole 11 is adjusted, and when a plurality of bristle clusters 3 are adjusted at the same time, the contact surface of the bristles 31 can be matched with a surface to be scanned, so that the cleaning efficiency is improved; meanwhile, the universal joint 21 between the broom rod 2 and the brush hair mounting rack 1 can ensure that the broom can adapt to surfaces to be swept at various angles, thereby further improving the cleaning efficiency. Since the slider 32 tends to rotate due to a static friction force given to the slider 32 by the driving of the lead screw 42, the slider 32 cannot be efficiently moved up and down while rotating, and thus the slider 32 can be effectively restricted from rotating by the flat surface of the side wall of the through-hole 11.
In this embodiment, the lifting mechanism 4 includes a limiting column 41A and a screw rod 42, and the bottom of the limiting column 41A and the top of the screw rod 42 are integrally formed; a first annular protrusion 421 is arranged on the side surface of the screw rod 42, an annular groove 111 matched with the first annular protrusion 421 is arranged on the side wall of the through hole 11, the first annular protrusion 421 is clamped in the annular groove 111, and the limiting column 41A is exposed out of the top of the through hole 11; the sliding block 32 is provided with an internal thread through hole matched with the screw rod 42, and the screw rod 42 is matched and connected with the sliding block 32 through the internal thread through hole; the bristles 31 are disposed at the edge of the internally threaded through hole at the bottom of the slider 32. The screw rod 42 enables the limiting column 41A to be rotatably connected with the bristle mounting frame 1 through the matching of the first annular bulge 421 and the annular groove 111; the screw rod 42 can rotate by rotating the limiting column 41A exposed out of the top of the through hole 11, and because the screw rod 42 is matched with the internal thread through hole and the screw rod 42 is fixed in the vertical direction, the internal thread through hole does lifting motion so as to drive the sliding block 32 to do lifting motion; moreover, because the slider 32 is provided with an internally threaded through hole, the brush 31 can be disposed only at the edge of the through hole 11.
In this embodiment, the opening at the lower part of the through hole 11 is provided with a second annular protrusion 12 for limiting the sliding block 32 from falling, so as to prevent the sliding block 32 from separating from the bristle mounting frame 1.
In this embodiment, the length of the brush staples 31 is longer than that of the through hole 11 to prevent the brush staples 31 from being caught by the second annular projection 12 when they are completely inserted into the through hole 11 and then adjusted.
In this embodiment, the slider 32 is made of plastic, and the bristles 31 and the slider 32 are integrally formed by heat melting, so as to prevent the bristles 31 from falling off after long-term use.
In the embodiment, as shown in fig. 4, when the broom of the present invention is used to clean the concave surface, the limiting posts 41A on both sides of the broom are rotated to retract the bristle tufts 3 on both sides into the through holes 11, so that the brush 31 of the broom is shaped as shown in fig. 4 to conform to the shape of the concave surface, thereby improving the cleaning efficiency.
Example two
As shown in fig. 5: the difference between the present embodiment and the first embodiment is: the lifting mechanism 4 enables the sliding block 32 to move up and down in the through hole 11 in a mode of being driven by the screw rod 42, so that the length of the bristles 31 of the bristle tufts 3 exposed out of the bottom of the through hole 11 is adjusted, and when a plurality of bristle tufts 3 are adjusted at the same time, the contact surface of the bristles 31 can be matched with a surface to be cleaned, so that the cleaning efficiency is improved; meanwhile, the universal joint 21 between the broom rod 2 and the brush hair mounting rack 1 can ensure that the broom can adapt to surfaces to be swept at various angles, thereby further improving the cleaning efficiency. Since the slider 32 tends to rotate due to a static friction force given to the slider 32 by the driving of the lead screw 42, the slider 32 cannot be efficiently moved up and down while rotating, and thus the slider 32 can be effectively restricted from rotating by the flat surface of the side wall of the through-hole 11.
In this embodiment, another implementation manner of the lifting mechanism 4 includes a limiting boss 41B and an internal thread through hole, the limiting boss 41B has a large upper part and a small lower part, the shape and size of the lower part of the limiting boss 41B are matched with the through hole 11, and the internal thread through hole is arranged at the center of the limiting boss 41B; the outer side wall of the lower part of the limiting boss 41B is provided with a first annular protrusion 421, the side wall of the through hole 11 is provided with an annular groove 111 matched with the first annular protrusion 421, the first annular protrusion 421 is clamped in the annular groove 111, and the top of the limiting boss 41B is exposed out of the top of the through hole 11; the top of the sliding block 32 is fixedly connected with a screw rod 42 matched with the internal thread through hole, the screw rod 42 is matched and connected with the limiting boss 41B through the internal thread through hole, and the lifting mechanism 4 is realized in a manner that a first annular bulge 421 at the lower part of the limiting boss 41B is matched with the annular groove 111, so that the limiting boss 41B is rotatably connected with the bristle mounting frame 1; the internal thread through hole can be rotated by rotating the limiting boss 41B exposed at the top of the through hole 11; because the lead screw 42 is engaged with the internal threaded through hole and the internal threaded through hole is fixed in the vertical direction, the lead screw 42 makes a lifting motion to drive the slider 32 to make a lifting motion.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
