Patent number: 10912438Abstract: The disclosure relates to a sweeping robot and a cleaning device. The sweeping robot includes: a flexible roller for cleaning the ground, a roller motor for driving the flexible roller to rotate, a pressing member for deforming the flexible roller to press out sewage. Clean water in the clean water sink flows through the clean water hole to the flexible roller. The sweeping robot further includes a sewage sink. The sewage sink is provided with a sewage hole is adjacent to the pressing member. The pressing member deforms the flexible roller, causing sewage to be pressed out of the flexible member and flow through the sewage hole into the sewage sink. The sewage sink is separated from the clean water sink. The cleaning device of the present invention has strong cleaning ability, and the flexible roller is easy to clean.Type: GrantFiled: July 31, 2018Date of Patent: February 9, 2021Assignee: HiZero Technologies Co., Ltd.Inventor: Yang Li

Patent number: 10912436Abstract: A cleaning mechanism for clearing a cleaning roller of a cleaner. The cleaning mechanism includes: a cleaning roller for cleaning ground, a clearing component operating to clearing the cleaning roller, and a power unit. The clearing component includes a rotation body and a plurality of clearing elements disposed on the rotation body for clearing a surface of the cleaning roller. The power unit operates to drive the rotation body and the clearing elements to rotate along with the cleaning roller in the same direction. During the rotation of the cleaning roller, the trash is cleared by the clearing elements.Type: GrantFiled: November 26, 2018Date of Patent: February 9, 2021Assignee: HiZero Technologies Co., Ltd.Inventors: Yang Li, Yong Zhang

Patent number: 10898048Abstract: A sponge roller, a cleaning roller assembly, and a floor cleaner. The sponge roller includes an outer layer and an inner layer. The outer layer is sleeved on the inner layer; the inner layer is made of non-absorbent sponge, and the outer layer is made of absorbent sponge. The sponge roller can be made with a large thickness, thus improving the cleaning capacity of the cleaner. The water is mainly stored in the outer layer, so it can be squeezed out without the exertion of much more external force, and thus the resistance against the rotation of the sponge roller is negligible, thus saving the energy consumption.Type: GrantFiled: August 20, 2018Date of Patent: January 26, 2021Assignee: HiZero Technologies Co., Ltd.Inventors: Yang Li, Yong Zhang

Patent number: 10786134Abstract: The disclosure provides a water channel assembly including a channel shell and a filtering piece. The water channel is disposed on the surface of a cleaning roller in a seal and overturn mode so that the cleaning roller is washed by water flowing in the water channel. The filtering piece is laid in the water channel and faces the surface of the cleaning roller. As a result, the solid trash on the cleaning roller is filtered by the filter element and cannot enter the water channel, thus preventing the blockage of the waterway of the water supply system.Type: GrantFiled: July 2, 2018Date of Patent: September 29, 2020Assignee: HIZERO TECHNOLOGIES CO., LTD.Inventors: Yang Li, Yong Zhang

Patent number: 10765283Abstract: The disclosure relates to a bidirectional mobile cleaning device comprising a garbage collection box, a first rolling member disposed at one end of the garbage collection box, and a second rolling member disposed at the other end of the garbage collection box. The first rolling member rotates to collect and adsorb garbage and sewage on the ground and feed it into the garbage collection box. The second rolling member rotates in a direction opposite to the direction with which the first rolling member rotates to collect and absorb garbage and sewage on the ground and feed it into the garbage collection box. The bidirectional mobile cleaning device is driven to move based on a speed difference between the first and second rolling members.Type: GrantFiled: August 10, 2018Date of Patent: September 8, 2020Assignee: HiZero Technologies Co., Ltd.Inventor: Yang Li
