[0002] A sofa is a very common piece of furniture, widely used in family living rooms, hotels, business meetings and other occasions. The sofa has a comfortable sitting feeling and various shapes, and can adapt to various decoration styles, so it is deeply loved by people. With the continuous development of social technology, people's consumption level is also constantly improving. Especially in families with a courtyard, sofas are often placed in the courtyard for outdoor use. However, when the sofa is placed outdoors for a long time, the seat cushion will be contaminated with dust in the air. Therefore, it needs to be cleaned every time you sit on it, which brings inconvenience to users. Moreover, ordinary cleaning devices only sweep over, and can only take away the floating dust on the sofa, and the dust attached to the surface of the sofa cannot be completely removed. To solve the above problems, an outdoor sofa with an easily cleanable surface that reciprocally disturbs and cleans with a cleaning brush is provided. Content of the Utility Model

[0010] Preferably, a first tooth track is provided on one side of the limiting plate close to the movable armrest, a receiving gear is provided on the rotating shaft, and the receiving gear is meshed with the first tooth track.

[0011] Preferably, a dust removal groove is provided in the movable armrest, and a dust suction component is provided on the side wall of the sofa body. The dust suction component is communicated with the dust removal groove through a dust suction pipe.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. During the movement of the movable armrest, the incomplete gear meshes with the intermittent tooth rail to drive the rotating shaft to rotate a certain angle. Through the restoring force of the torsion spring, it rotates in the reverse direction. Repeating this way can drive the cleaning brush to swing and clean the surface of the sofa body, separating the dust attached to the surface of the sofa body, changing the phenomenon that the traditional cleaning device can only take away the floating dust on the upper part by simply sweeping, and making the surface of the sofa body cleaner.

[0014] 2. The dust removal groove is arranged outside the cleaning brush. After the cleaning brush disturbs the dust attached to the sofa body, the dust suction component can suck the dust through the dust suction pipe to achieve the purpose of dust removal.

[0026] Embodiment 1

[0027] Referring to Figures 1-6 , an outdoor sofa with an easily cleanable surface, including a sofa body 1, a backrest 3 is provided on the rear surface of the sofa body 1, a limiting plate 11 is provided at the top of the sofa body 1, a movable armrest 2 is movably connected to the top of the sofa body 1, the movable armrest 2 is snap-fitted with the limiting plate 11, a rotating shaft 21 is rotatably connected to the inner wall of the movable armrest 2, a cleaning brush 211 is provided on the rotating shaft 21, a torsion spring 212 is sleeved on the rotating shaft 21, the fixed end of the torsion spring 212 is fixedly connected to the inner wall of the movable armrest 2, and the movable end of the torsion spring 212 is fixedly connected to the circumferential side wall of the rotating shaft 21. An intermittent toothed rail 112 is provided at the top of the sofa body 1 near the backrest 3. An incomplete gear 213 is provided on the outer end of the rotating shaft 21. The incomplete gear 213 is meshed with the intermittent toothed rail 112. By meshing the incomplete gear 213 with the intermittent toothed rail 112, the rotating shaft 21 can be driven to rotate a certain angle, and by the restoring force of the torsion spring 212, it rotates in the reverse direction. Repeating like this can drive the cleaning brush 211 to swing and clean the surface of the sofa body 1, so that the dust attached to the surface of the sofa body 1 is separated, changing the phenomenon that the traditional cleaning device can only take away the floating dust on the upper part by simply sweeping it over, making the surface of the sofa body cleaner.

[0028] Further, a connecting rod 23 is provided at the bottom end of the movable armrest 2. The connecting rod 23 is slidably connected to the top of the sofa body 1. A movable block 231 is provided at the bottom end of the connecting rod 23 inside the sofa body 1. A bidirectional lead screw 24 is rotatably connected to the inner wall of the sofa body 1. The bidirectional lead screw 24 is threadedly connected to the movable block 231. A motor 241 is provided inside the sofa body 1. The motor 241 is drivingly connected to the bidirectional lead screw 24 through a transmission belt 242.

[0029] Further, a first tooth rail 111 is provided on one side of the limiting plate 11 close to the movable armrest 2. A receiving gear 112 is provided on the rotating shaft 21. The receiving gear 112 is meshed and connected to the first tooth rail 111. After the surface of the sofa body 1 is cleaned, the movable armrest 2 approaches the limiting plate 11. At this time, the receiving gear 112 is meshed and connected to the first tooth rail 111, and one end of the bristles of the cleaning brush 211 rotates toward the limiting plate 11. At this time, the cleaning brush 211 can be received to prevent contact with the cleaning brush 211 when holding the armrest.

[0030] Start the motor 241 to drive the bidirectional lead screw 24 to rotate, thereby driving the movable block 231 to move centrically, and then driving the movable armrest 2 to move centrically. During the movement of the movable armrest 2, the rotating shaft 21 can be driven to rotate a certain angle by the meshing connection between the incomplete gear 213 and the intermittent tooth rail 112, and reverse rotation is carried out by the restoring force of the torsion spring 212. Repeating this way can drive the cleaning brush 211 to swing and clean the surface of the sofa body 1, separating the dust adhering to the surface of the sofa body 1; after the surface of the sofa body 1 is cleaned, the movable armrest 2 approaches the limiting plate 11. At this time, the receiving gear 112 is meshed and connected to the first tooth rail 111, and one end of the bristles of the cleaning brush 211 rotates toward the limiting plate 11. At this time, the cleaning brush 211 can be received.

[0031] Embodiment 2

[0032] Refer to Figures 1-6 , a dust removal groove 22 is formed inside the movable armrest 2. The dust removal groove 22 is arranged outside the cleaning brush 211 for sucking in the dust separated by the cleaning brush 211. A dust suction component 222 is provided on the side wall of the sofa body 1. The dust suction component 222 is communicated with the dust removal groove 22 through a dust suction pipe 221.

[0033] The dust removal groove 22 is arranged outside the cleaning brush 211. After the cleaning brush 211 disturbs the dust adhering to the sofa body 1, the dust suction component 222 can suck in the dust through the dust suction pipe 221 to achieve the purpose of dust removal.

[0034] Working principle: Start the motor 241 to drive the bidirectional lead screw 24 to rotate, thereby driving the moving block 231 to move centrically, and then driving the moving armrest 2 to move centrically. During the movement of the moving armrest 2, the incomplete gear 213 meshes with the intermittent tooth rail 112 to drive the rotating shaft 21 to rotate a certain angle. Through the restoring force of the torsion spring 212, it rotates in the reverse direction. Repeating this way can drive the cleaning brush 211 to swing and clean the surface of the sofa body 1, so that the dust attached to the surface of the sofa body 1 is separated;

[0035] The dust collection groove 22 is arranged outside the cleaning brush 211. After the cleaning brush 211 disturbs the dust attached to the sofa body 1, the dust suction component 222 can suck the dust through the dust suction pipe 221;

[0036] After the surface of the sofa body 1 is cleaned, the moving armrest 2 moves closer to the limit plate 11. At this time, the receiving gear 112 meshes with the first tooth rail 111, and one end of the bristles of the cleaning brush 211 rotates towards the limit plate 11. At this time, the cleaning brush 211 can be received.
