Self-generating knob device

Abstract

The invention relates to a self-generating knob device. The device comprises a knob body and an electric assembly which are arranged on the two sides of a panel, wherein the knob body comprises a shell, a generating coil and a first circuit board, the generating coil and the first circuit board are arranged in the shell, and the generating coil is electrically connected with the first circuit board; the electric assembly comprises an annular magnet; and the generating coil can cut the magnetic induction line of the magnet to generate power in the rotating process of the knob body. According tothe self-generating knob device, self-generating is achieved through the magnet and the generating coil, then electric energy is provided for the knob body independently, so that when some electric devices with small power supply are arranged on the knob body, a power source does not need to be additionally installed, and the self-generating electric quantity is large enough for the electric devices to work. And the knob body does not need to be charged in the use process, so that the use convenience is improved. Assembly and disassembly are not needed, and thus, the service life of the knobbody can be correspondingly prolonged.

Description

technical field [0001] The invention relates to a self-generating knob device. Background technique [0002] The knobs used on existing electrical appliances usually need to punch holes on the electrical panel, and then install the knobs, and then perform adjustment and control. However, such knobs are often not well sealed, and it is easy for water to enter and cause damage to the internal electrical components. In order to avoid the problem of damage to the panel, there is an independently set knob structure. For example, the authorized announcement number is CN206320810U (application number is 201621167593.1), the Chinese utility model patent "a stove controlled by a fire knob", wherein the stove controlled by a fire knob includes a stove body, a stove surface, and a stove that is installed in the stove body to adjust the stove. The control valve of the firepower, and the control valve installed on the furnace surface to control the control valve, the control valve inclu...

Problems solved by technology

In order to increase the function of the knob, electrical components such as circuit boards, display screens, and indicator lights are also installed in the existing non-contact knobs. In this case, it is necessary to set up a corresponding power supply to supply power to these electrical components. In this case, the power supply needs to be replaced. Or the charging of the power supply is relatively troublesome to use
