Description

A brush and sweeping brush

technical field

The utility model relates to a brush and a sweeping brush.

Background technique

At present, household sweeping machines have become very popular. The sweeping brushes and sweeping methods used in sweeping machines usually use rotor-type brushes, dust box roller brushes, and vacuum cleaners. Although this method can handle tiny dust , debris and other garbage, because the suction port is at a certain distance from the ground when vacuuming, the suction force of the vacuum port is attenuated. Once the weight of the garbage is slightly larger (the volume is slightly larger), the vacuum port cannot effectively remove the garbage. .

Utility model content

The main purpose of the utility model is to provide a sweeping brush, which collects the garbage to the dust suction port through the spiral bristles, and uses the bristles of the brush to form a dust suction channel, which effectively concentrates the suction force of the dust suction port and reduces the suction power. loss, effectively increasing the weight range of garbage removal.

To achieve the above purpose, the technical scheme adopted by the present utility model is:

A brush includes a fixing plate, bristles are fixed on the lower surface of the fixing plate, the bristles are arranged in a spiral shape from the outer edge of the fixing plate to the center, and the center of the fixing plate is provided with a through hole. The bristles are arranged in a spiral shape so that the brush rotates while the sweeping machine is moving. Using the spiral convergence effect, the garbage is gathered to the central through hole for collection, which improves the effect of the suction port for garbage absorption.

Sweeping brushes, including,

A connecting sleeve, one end is fixedly connected to the suction port of the sweeper, and the other end is rotatably connected to the fixing plate of the brush;

The upper part of the fixing plate is fixedly connected with a transmission device for transmission connection with the sweeper.

By arranging a sweeping brush installed on the sweeping machine, the connecting sleeve is connected to the suction pipe of the sweeping machine through threads, and then connected to the driving device of the sweeping machine through the transmission device, so that the sweeping brush can rotate and vacuum at the same time, so that Sweeping machines are able to pick up heavier litter.

Further, a bearing is sleeved and fixed on the connecting sleeve, a fixing sleeve is installed on the outer ring of the bearing, the lower surface of the fixing sleeve is fixedly connected to the upper surface of the fixing plate, and the upper part of the fixing sleeve is fixedly connected with a transmission device. The inner ring cannot be rotated by the fixed connection between the inner ring of the bearing and the connecting sleeve. A fixing sleeve is installed on the outer ring of the bearing. The fixing sleeve is fixedly connected with the fixing plate of the brush, and then the transmission device is fixedly connected on the upper part of the fixing sleeve through the driving device of the sweeping machine. Transmission, so that the brush installed on the sweeping brush can be rotated, and the collected garbage can be sucked out through the through hole of the brush fixing plate through the connecting sleeve through the dust suction port of the sweeping machine.

Further, the transmission device is a ring gear. Rotation is realized through the transmission connection between the ring gear and the driving device of the sweeping machine.

Further, the connecting sleeve is provided with protruding strips along the length direction, and the protruding strips are inserted into the matching through grooves on the inner ring of the bearing. By setting the convex strips to fix the inner ring of the bearing, the inner ring can be effectively placed to follow the rotation of the outer ring, and the installation position of the bearing can be adjusted as required.

Further, a spring is also sleeved on the connecting sleeve, one end of the spring is pressed against the lower surface of the limit plate A set on the connecting sleeve, and the other end is pressed against the upper surface of the fixing sleeve, and the lower end of the connecting sleeve is also fixedly connected. Limiting plate B to prevent the brush from coming off the connecting sleeve. By setting one end of the spring against the limit plate A, and the other end against the upper part of the fixing sleeve, the brush is guaranteed to always adhere to the bottom surface, and by setting the limit plate B, the entire brush can be fixed with the connecting sleeve.

One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: the utility model uses the spiral bristles to collect the garbage when rotating, and the dust suction port absorbs the collected bristles through the connecting sleeve. waste, reducing the waste of suction.
