Patent number: 11535442Abstract: A foam spray can comprises a motor pump, a foaming tube and a nozzle. The motor pump can be used to suck air and solution and pump out the liquid-gas mixture. One end of the foaming tube is connected to the motor pump for transmitting the liquid-gas mixture pumped by the motor pump and fully mixing the air with the solution to produce foam. The nozzle is connected to the other end of the foaming tube to spray foam. The length of the foaming tube is between 10 to 500 cm, the tube inner diameter is between 0.8 to 20 mm, and the pressure of the liquid-gas mixture in the tube is between 8 to 32 PSI, thereby to provide sufficient time, space and conditions for the mixing of the air and the solution in the foaming tube to fully mix the air and the solution, and then to spray abundant foam from the nozzle.Type: GrantFiled: January 26, 2021Date of Patent: December 27, 2022Assignee: FAIRWAY ELECTRONIC CO., LTD.Inventors: Lin-Han Yen, Yu-Jen Fang

Publication number: 20220216763Abstract: A rotating machine comprises a housing, a rotating shaft and an oil seal structure. The housing has an opening. The rotating shaft extends from the inside of the housing through the opening to the outside of the housing. The oil seal structure is set at the opening. The oil seal structure includes a body, an annular groove and an annular elastic structure. The body has a through hole to accommodate the rotating shaft. The annular groove is located on the surface of the body facing the outside of the housing and surrounds the through hole. The annular elastic structure is arranged in the annular groove to apply force to the rotating shaft. Thereby, the connection between the oil seal structure and the rotating shaft can be strengthened to ensure the sealing effect and prevent external moisture from entering the housing.Type: ApplicationFiled: January 5, 2021Publication date: July 7, 2022Inventors: LIN-HAN YEN, YU-JEN FANG
