The utility model discloses a self-cleaning stock bin which comprises a stock bin body and a cleaning assembly. The upper end and the lower end of the stock bin body are open. The cleaning assembly is located on the inner side of the bin body and used for rotationally cleaning the inner side wall of the bin body. According to the utility model, the cleaning assembly is designed to rotatably clean materials with higher viscosity on the inner side wall of the stock bin body, so that time and labor are saved, and the problem of sample mixing caused by residual samples in the stock bin body is avoided.

This utility model relates to a head massager, comprising a shell and a rear shell. A massage assembly is located at the front of the shell, and an essential oil assembly is located in the middle of the massage assembly. A light panel assembly, a drive assembly, a circuit board, and a rechargeable battery are located at the rear of the shell. The massage assembly includes multiple sets of massage rods spaced apart from each other, a flexible cover, a support, a swing seat, and a track gear composite component. The front of the swing seat is fastened to the rear of the massage rod. A spherical massage head is located at the front end of the massage rod, and a ball is located at the rear of the swing seat. This ball slides in a slide rail and simultaneously swings radially with the slide rail. Each set of massage rods is an integrated structure, molded together in a silicone mold used for producing the flexible cover, saving assembly time and improving work efficiency. The spherical massage head at the front end of the massage rod effectively prevents tingling sensation on the head during massage. The entire product is fully sealed, improving waterproofing and reducing mechanical noise. This design is compact, portable, and easy to carry.
