Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

As shown in fig. 1-4, a brush plate structure of a sweeper comprises a rotating body 1 with a cavity formed therein, a bristle connecting plate 2 slidably mounted in the cavity 112 up and down, an elastic member 3 mounted in the cavity 112 and used for providing upward elastic force to the bristle connecting plate 2, bristles 21 mounted at the bottom of the bristle connecting plate 2, and an air bag 3. The rotating body 1 is a disk-shaped structure and is driven to rotate around its own axis by an external driving mechanism. The bottom of the rotating body 1 is machined with an opening 113 communicating with the cavity 112. The brush staples 21 are movably protruded below the bottom of the rotating body 1 through the openings 113. The above-mentioned elastic member 3 is preferably a support spring which is vertically arranged and is connected between the bristle attachment plate 2 and the inner bottom wall of the cavity 112. The air bag 4 is mounted between the inner top wall of the cavity 112 and the bristle attachment plate 2. The upper part of the air-bag 4 rests against the inner top wall of the cavity 112. The lower part of the air bag 3 is abutted against the bristle connecting disc 2. An air nozzle 41 is attached to the airbag 4. The air nozzle 41 extends upward through the air tube and out above the top of the rotating body 1. It is preferable that the air nozzle 41 is installed on the rotation central axis of the rotating body 1. Through the structural design, in the initial state, the part of the bristles 21 is positioned in the cavity 112, the air bag 4 is inflated through the air nozzle 41, the air bag 4 expands to further press the bristle connecting disc 2 to move downwards, and the bristles 21 move downwards along with the bristle connecting disc. After the air bag 4 is deflated, the air bag 4 is contracted, the bristle connecting disc 2 moves upwards under the action of the elastic element 3, and the part of the bristles 21 is retracted into the cavity 11.

As shown in fig. 4, 5 and 6, to facilitate the installation of the whole structure, the rotating body 1 includes a lower housing 11 and an upper cover 12, a cavity 112 is processed inside the lower housing 11, an opening 113 is installed at the bottom of the lower housing 11, an opening communicated with the cavity 112 is processed at the top of the lower housing 11, and the upper cover 112 is covered on the opening and connected with the lower housing 11 through a bolt. Through the structural design, the elastic piece 3, the bristle connecting disc 2 and the air bag 4 are convenient to mount and dismount.

As shown in fig. 5 and 7, the bristle connecting plate 2 is specifically installed in a manner that a plurality of sliding grooves 111 are formed in the side wall of the cavity 112, the sliding grooves 111 extend in the vertical direction, a plurality of sliding blocks 22 are installed at the edge of the bristle connecting plate 2, and the sliding blocks 22 are slidably installed in the sliding grooves 21.

As shown in fig. 1, 2, 3, and the like, the upper portion of the airbag 4 is fixedly connected to the upper cover 11, and the air faucet is also fixedly connected to the upper cover 11 via the flange 5. The flange 5 is two flanges, one of which is mounted on the upper cover 11, and the other of which 5 is mounted on an air pipe connected to the air nipple 41.

When the sweeper is used specifically, the rotating body 1 is installed on a front end support of the sweeper and can rotate around the central axis of the rotating body 1, and the rotating body 1 is driven to rotate through the driving mechanism. The air nozzle 4 is communicated with an air source arranged on the sweeper through a rotary joint. When cleaning, the air bag 4 is inflated, the air bag 4 expands to press the bristle connecting disc 2 to move downwards, the bristles 21 move downwards and contact with the ground, and cleaning operation is started. When the air bag 4 is deflated and the air bag 4 is contracted when the air bag is not in use, the bristle connecting disc 2 moves upwards under the action of the elastic element 3, and the part of the bristles 21 retracts into the cavity 11 to leave the ground. The bristles are not in contact friction with the ground, so that the service life of the bristles is effectively prolonged.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transformation that the content of the specification does, or directly or indirectly use in other related technical fields, all including in the same way the patent protection scope of the present invention.
