Patent number: 11787009Abstract: An electric tool includes an output member, a motor, and a housing. The motor includes a rotor shaft, a rotor core, and a stator component. The rotor shaft is configured to rotate around a first axis. The stator component includes a coil winding. The stator component surrounds the first axis to separate the accommodation cavity into a first space and a second space. The first space includes a first end and a second end. The motor further includes a first end cover and a second end cover. The first end cover is disposed at the first end of the first space. The second end cover is disposed at the second end of the first space. A passage is formed between the second end cover and a structure surrounding the first space, and the passage is configured to place the first space into communication with the second space.Type: GrantFiled: September 11, 2018Date of Patent: October 17, 2023Assignee: Nanjing Chervon Industry Co., Ltd.Inventors: Yanfeng Fan, Haijing Wang, Baoshan Li, Guoming Tong, Tao Tao, Xiang Zhao

Publication number: 20230286130Abstract: A power tool includes a shaft locking assembly and an electric motor. The shaft locking assembly includes a first state where a chuck is restrained from rotating and a second state where the chuck is released to rotate. The shaft locking assembly includes multiple locking portions and an execution portion. The multiple locking portions are formed on or connected to a drive shaft or the chuck. The execution portion is optionally engaged with at least one locking portion. When the execution portion moves to a first position, the execution portion is engaged with the at least one locking portion such that the shaft locking assembly is in the first state. The electric motor includes a stop state where the first position is in the at least one locking portion when the electric motor stops.Type: ApplicationFiled: December 28, 2022Publication date: September 14, 2023Inventors: Guoming Tong, Masatoshi Fukinuki, Xiang Zhao, Jiayu Li, Lei Tian, Jun Le, Liangzhe Wang

Publication number: 20230202020Abstract: A power tool includes a power mechanism including a drive shaft; an oscillating mechanism; an airflow element connected to the drive shaft; a heat conducting portion supported on the drive shaft, where the airflow element is disposed on the heat conducting portion. The oscillating mechanism includes a support assembly sleeved on the drive shaft and an oscillating member. Heat generated by the oscillating mechanism is conducted to the heat conducting portion through the drive shaft, the heat conducting portion has a thermal conductivity greater than or equal to 50 W/m•°C, and a ratio of an axial distance L1 of a portion of the heat conducting portion in contact with the drive shaft to a distance L2 of a thermally conductive portion of the drive shaft between the heat conducting portion and the support assembly is greater than or equal to 0.1 and less than or equal to 5.Type: ApplicationFiled: March 1, 2023Publication date: June 29, 2023Inventors: Masatoshi Fukinuki, Guoming Tong, Rui Zhan, Xiang Zhao, Pengpeng Xue
