The invention provides an oil-cooling and low-loss internal rotor permanent magnetic motor, which belongs to the motor field and aims to reduce the oil friction loss, to improve the heat radiation performance, and further to increase the power density of a motor applied to an oil-immersed environment. The invention comprises a stator and a rotor. The stator comprises a housing, a stator iron core, an insulation layer, a shaft direction key, a plurality of stator coils and two end covers. The rotor comprises a rotor shaft, a rotor magnetic yoke, two bearings and a plurality of magnetic steels. According to the invention, the two sides of the inner round arc face of each magnetic steel are cut with inner angles. The outer round face formed by the plurality of magnetic steels is provided with a flow guiding groove along the shaft direction in a rotation manner. The inner round face of the rotor magnetic yoke is provided with inclined flow passing grooves in the shaft direction. The plurality of inclined flow passing grooves are symmetrically distributed around the round circumference. When the stator iron core is casted into shape directly, a plurality of back flow holes are supposed to be reserved on the yoke part or a plurality of back flow grooves are reserved at the back to provide a passage for oil to circulate inside the motor. In an oil-immersed high temperature environment, when such a motor is used, the power density can be increased, therefore, making the motor of great practical value.

The invention discloses a preparation method of a shark bone pet molar toy, which is characterized in that it comprises the following steps: (1) freezing the fresh bone into a warehouse; (2) immediately sending the fresh bone to a cleaning workshop to remove the fresh bone Wash the remaining meat; (3) section the fresh bones to obtain the divided bones; (4) mature the divided bones and dry them at 50-80°C for 1-5 hours to obtain the dry bones; (5) dry the dried bones (6) Degrease, wash, and dry; (7) Place the product obtained in step (5) in a vitamin C solution and soak it at 40°C for 0-5 days to obtain The primary product; (8) adding meat to the primary product to obtain the finished product. The invention can produce a toy with suitable hardness and suitable for pets to bite, and can serve the purpose of providing pets with oil intake and prolonging the shelf life of shark bone pet teething toys.

The present invention provides an auxiliary filling device and a brake fluid filling system, wherein the auxiliary filling device is used on a hydraulic clutch pedal operating mechanism, the hydraulic clutch pedal operating mechanism includes a clutch master cylinder, and the auxiliary filling The injection device includes a housing and a filling piston. The housing is placed vertically. The housing is provided with a cavity. The bottom wall of the cavity is provided with a pipeline inlet. The pipeline inlet is used for communication. It is arranged at the oil outlet of the clutch master cylinder; the filling piston can be movable up and down and installed on the upper end of the cavity, and the filling piston has a seal that seals the pipeline inlet on its movable stroke position and open the communication position of the pipeline inlet. In the technical solution of the present invention, the auxiliary filling device is used to increase the vacuum degree in the clutch master cylinder to improve the filling and exhaust efficiency of the clutch master cylinder.
