Description

Technical Field

[0001] The utility model relates to the technical field of timers, in particular to a double-sided magnetic isolation timer. Background Art

[0002] A timer can be used to control the start and stop time of a machine. When used on a gas self-closing valve, it can act as a timer switch to prevent gas leaks. The gas self-closing valve is equipped with a magnetic element. While the magnetic field inside the self-closing valve controls the opening and closing of the valve, it also interferes with the operation of the timer. Since the working principle of a mechanical timer mainly relies on the operation of mechanical components, when the magnetic element is close to the mechanical timer, its magnetic field will affect the mechanical components, causing the operating speed of the components to change, which will affect the timing accuracy of the mechanical timer. In actual applications, people often take magnetic isolation measures above the timer to reduce the impact of the magnetic field on the timer. However, this approach fails to fully consider the possible impact of the magnetic field on the bottom of the timer, so it is necessary to improve it. Utility Model Content
