Patent number: 9273807Abstract: A sealing device of a level meter is acid-and-alkali-resistant and pressure-resistant, and has a flexible outer tube, a plug, a female union connector and a male union connector. The flexible outer tube has an expansion neck formed on a bottom end thereof. The plug is mounted in the expansion neck. The female union connector is mounted around the expansion neck. The male union connector engages the female union connector by means of threaded engagement. The male union connector has a through hole for tying a weight such that the flexible outer tube is stretched along a force of a gravitational force of the weight. As being wholly and uniformly subjected to the gravitational force of the weight, the male union connector is less damage-prone. Accordingly, the tensile strength of the level meter is effectively increased, and a life duration of the level meter therefore prolongs.Type: GrantFiled: April 23, 2014Date of Patent: March 1, 2016Assignee: FINETEK CO., LTD.Inventors: Chih-Wen Wang, Ting-Kuo Wu, Yu-Yen Lo, Chao-Kai Cheng

Patent number: 9111704Abstract: A rotary paddle level switch has a housing, a driving unit, two switches, a resilient member, a clutch, a transmission shaft, and a propeller. A resilient clip of the clutch holds a non-circular actuation section of the transmission shaft. When the driving unit drives the clutch to rotate, the transmission shaft and the propeller are driven by the clutch. When the propeller is rapidly rotated by suddenly exerting an excessively large external force thereon, as the resilient clip holds the transmission shaft by elastic force, the fast rotating transmission shaft removes itself from the holding of the resilient clip and is rotated without driving the resilient clip to rotate, thereby avoiding the transmission of the external force and damage to the driving unit. As the clutch just needs a clutch stand and a resilient clip to achieve the foregoing function, the level switch is structurally simple and relatively inexpensive.Type: GrantFiled: September 19, 2013Date of Patent: August 18, 2015Assignee: Finetek Co., Ltd.Inventors: Chih-Wen Wang, Ching-Jui Chen, Cheng-Tao Lee, Ting-Kuo Wu, Chao-Kai Cheng
