Description

  The present invention relates to a self-propelled cleaning device, and in particular, cleans a self-propelled cleaning device that performs a cleaning operation by moving independently, and has a main cleaning brush and a bottom cover on an outer cover of the main cleaning brush. The present invention relates to a brush bottom lid structure and a method for assembling and cleaning a brush.

  The inside of the device body of a known self-propelled cleaning apparatus is generally provided with a negative pressure mechanism that forms a negative pressure suction force and sucks dust on the cleaning surface from a dust suction port and collects it in a dust collection mechanism. Furthermore, in order to improve the dust collection effect on the cleaning surface, a concave arc-shaped storage chamber is provided at the bottom of the device body, a dust suction opening is opened on one side of the storage chamber, and the main cleaning brush is placed in the storage chamber. Pivot. Further, a side cleaning brush is additionally provided on the peripheral edge of the device main body, and dust outside the peripheral edge of the device main body is repelled and swept down by the main cleaning brush and collected by sucking into the dust collecting mechanism from the dust suction port.

  Furthermore, because the convenience of removal and cleaning of the main cleaning brush at a later date and the opening area of the concave arc-shaped storage chamber of the main cleaning brush is larger than the dust suction port, large foreign objects are sucked into the main cleaning brush attached to the storage chamber. In order to avoid damages and other undesired accidents, a removable cleaning brush bottom cover is provided at the opening of the storage chamber. The bottom lid is provided with a cut-out hole, and a plurality of work areas divided by a plurality of brazing materials are partitioned to reduce large foreign objects from being sucked into the storage chamber through the cut-out hole. In addition, on the bottom cover of the cleaning brush, from the rolling direction of the main cleaning brush toward the rear side, a scraper whose one end is in contact with the cleaning surface is provided, and dust that has been repelled by the main cleaning brush is collected and placed on the scraper, It is sucked by using a negative suction force to guide it to the dust mouth.

  In a self-propelled cleaning device equipped with a known main cleaning brush, both the scraper and the saddle material are provided on the bottom cover of the cleaning brush, and one end of the scraper must contact the cleaning surface. Therefore, all the scrapers of the bottom cover of the known cleaning brush are provided below the brazing material, and are tightened to the lower side of the bottom cover of the cleaning brush by screws. On the other hand, it is difficult to predict the environment in which the self-propelled cleaning device moves. The vibrations that form when cleaning a cleaning surface can cause accidents such as a family member stepping on it or an infant accidentally putting it in the mouth, such as a screw or other part loosening or falling to the cleaning surface. The result is immeasurable. Furthermore, if the parts that have been pulled out are sucked into the main body of the equipment, damage to the inside of the equipment will occur. Influence. In addition to this, when the self-propelled cleaning device moves, the scraper receives component force from the back and the bottom, while all parts are fastened and fixed from the bottom to the bottom cover of the cleaning brush. Contrary to the mounting direction and the downward component force, the upward tightening fixing force cancels out the downward component force, and the stability of the scraper after mounting is lowered. Thus, over time, the worst case where the screw loosens under the influence of reverse force and vibration over a long period of time may fall off the cleaning surface.

  Therefore, an object of the present invention is to provide a bottom cover structure for a cleaning brush of a self-propelled cleaning device in which a scraper fixture of the bottom cover of the cleaning brush has better assembly stability and can reduce an accident of loosening or coming out. provide.

  Another object of the present invention is to assemble the bottom cover of the cleaning brush of the self-propelled cleaning device in which the scraper fitting of the bottom cover of the cleaning brush has better assembly stability and can reduce the accident of loosening or coming out. Provide a method.

  Another object of the present invention is to provide a wipe cleaning method for the bottom cover of the cleaning brush of the self-propelled cleaning device in which the scraper of the bottom cover of the cleaning brush has appropriate elasticity and can be adapted to the environment of the cleaning surface. provide.
