DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-4 The utility model provides a self-cleaning device for an automatic sweeping machine, including a sweeping machine housing 1, a cleaning mechanism 2 is installed in the sweeping machine housing 1, an anti-curling mechanism 3 is arranged in front of the cleaning mechanism 2 in the sweeping machine housing 1, and a collecting mechanism 4 is installed in front of the anti-curling mechanism 3 in the sweeping machine housing 1.

[0023] The cleaning mechanism 2 facilitates cleaning of the floor surface, and the anti-curling mechanism 3 facilitates the self-cleaning function of the cleaning mechanism 2, so that the hair is cleaned inside the cleaning mechanism 2 to prevent entanglement from affecting the normal operation of the device. At the same time, the collecting mechanism 4 facilitates centralized cleaning of the hair, thereby improving the practicability of the device.

[0024] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that the cleaning mechanism 2 includes a motor 201, an output end of the motor 201 is fixedly connected to a fixed shaft 202 and is rotatably connected to the sweeper housing 1 through a bearing, a cleaning roller 203 is fixedly connected to the fixed shaft 202, a cleaning groove 204 is provided on the surface of the cleaning roller 203, the cleaning roller 203 is provided with an opening at the bottom of the sweeper housing 1 and protrudes from the bottom of the sweeper housing 1, a plurality of cleaning grooves 204 are provided, and a plurality of cleaning grooves 204 are arranged at intervals on the cleaning roller 203, and the cleaning roller 203 is made of a flexible brush material.

[0025] The cleaning roller 203 is driven to rotate by the motor 201 to clean the floor. At this time, the hair on the floor will be cleaned by the cleaning roller 203 and the floor will be cleaned at the same time.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the anti-curling mechanism 3 includes a half gear 301, which is fixedly connected to the fixed shaft 202 and arranged on the right side of the sweeping machine housing 1. A driven gear 302 is meshed with the front of the half gear 301, and a connecting shaft 303 is fixedly connected in the middle of the driven gear 302 and is rotatably arranged in the sweeping machine housing 1 through a bearing. A plug-in strip 304 is fixedly connected to the surface of the connecting shaft 303 close to the cleaning roller 203, and a positioning plate 305 is rotatably connected to the left side of the connecting shaft 303. The positioning plate 305 is fixedly connected to the sweeping machine housing 1, and a torsion spring 306 is sleeved on the outside of the connecting shaft 303 on the left side of the positioning plate 305. A plurality of plug-in strips 304 are provided, and the plurality of plug-in strips 304 are provided corresponding to the cleaning grooves 204, and are inserted into the cleaning roller 203 through the cleaning grooves 204, and the two ends of the torsion spring 306 are respectively connected to the connecting shaft 303 and the positioning plate 305.

[0027] The rotation of the fixed shaft 202 drives the half gear 301 to rotate, so that when the sweeping machine housing 1 is meshed with the driven gear 302, the connecting shaft 303 is driven to rotate, and then the plug-in strip 304 is rotated. Through the contact between the plug-in strip 304 and the cleaning roller 203, the hair is entangled on the plug-in strip 304, and the hair is separated from the cleaning roller 203 through the plug-in strip 304, avoiding the malfunction of the sweeping machine, and realizing the work of cleaning the hair on the cleaning roller 203, so as to achieve the self-cleaning effect of the cleaning roller 203.

[0028] According to the above working process, it can be known that: through the anti-curling mechanism 3, after the floor is cleaned by the cleaning mechanism 2, it is convenient to timely separate the cleaned hair or the longer rope from the cleaning mechanism 2 to prevent entanglement that affects the normal operation of the sweeper, thereby improving the cleaning effect.

[0029] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that the collecting mechanism 4 includes a collecting frame 401, which is movably arranged on the front side of the sweeping machine housing 1, and sliders 403 are fixedly connected to the bottom of the left and right sides of the collecting frame 401, and the sliders 403 are correspondingly provided with matching slide grooves 404 in the sweeping machine housing 1, and a combing strip 402 is openly arranged and fixedly connected on one side of the collecting frame 401 near the plug-in strip 304, and the combing strip 402 is matched with the plug-in strip 304, and grooves 4021 and protrusions 4022 are arranged on the combing strip 402, and the grooves 4021 and the protrusions 4022 are alternately arranged on the combing strip 402 and symmetrically arranged front and back.

[0030] The plug-in strip 304 is matched and inserted into the combing strip 402. The groove 4021 and the protrusion 4022 provided on the combing strip 402 block the hair on the plug-in strip 304, thereby facilitating the hair to be detached from the plug-in strip 304 and collected in the collection frame 401. The hair collection is realized, centralized cleaning is facilitated, and the cleanliness of the device is improved.

[0031] This scheme has the following working process: when this device is used, under the operation of the sweeper, the cleaning roller 203 is driven to rotate by the motor 201 to clean the floor. At this time, the hair on the floor will be cleaned and adhered by the cleaning roller 203, and the half gear 301 is driven to rotate under the rotation of the fixed shaft 202, so that when the tooth block on the half gear 301 is meshed with the driven gear 302, the connecting shaft 303 is driven to rotate, and then the plug-in strip 304 is rotated, and the contact between the plug-in strip 304 and the cleaning roller 203 makes the hair entangled on the plug-in strip 304, and the hair is separated from the cleaning roller 203 by the plug-in strip 304, so as to avoid sweeping. In case of machine failure, the plug-in strip 304 is rotated by the connecting shaft 303, and the plug-in strip 304 is matched and inserted into the combing strip 402. The groove 4021 and the protrusion 4022 provided on the combing strip 402 block the hair on the plug-in strip 304, thereby facilitating the hair to be detached from the plug-in strip 304 and collected in the collecting frame 401. At the same time, when the half gear 301 is not engaged with the driven gear 302, the resetting action of the torsion spring 306 allows the plug-in strip 304 to be reset through the connecting shaft 303 and reinserted into the cleaning roller 203, forming a cycle, thereby achieving self-cleaning of the hair on the cleaning roller 203, thereby improving the cleaning effect.

[0032] In summary: by setting the anti-curling mechanism 3, after the floor is cleaned by the cleaning mechanism 2, it is convenient to timely detach the cleaned hair or the longer rope from the cleaning mechanism 2 to prevent entanglement from affecting the normal operation of the sweeper, thereby improving the cleaning effect; by setting the collecting mechanism 4, in cooperation with the anti-curling mechanism 3, it is convenient to collect the cleaned hair in a centralized manner, further improving the cleaning efficiency of the anti-curling mechanism 3 on the cleaning mechanism 2, and at the same time facilitating the cleaning of the collected hair to prevent contamination caused by bacterial growth.
