Abstract

The invention discloses a boosting device of an electric rocking chair, which comprises a guiding insulation cylinder; a metal sports body is arranged in the insulation cylinder, the upper part in the insulation cylinder is provided with a normally closed switch, the middle part in the insulation cylinder is provided with an electric contact which is connected with an electromagnetic coil, and the lower part outside the insulation cylinder is provided with the electromagnetic coil; the upper end of the metal sports body is connected with an insulator, and the insulator is provided with a conductive ring matched with the electric contact; and the upper end of the insulator is connected with the normally closed switch through a flexible part, and the normally closed switch is connected withthe power supply of the electromagnetic coil. By adopting the structure and only taking the metal sports body as the sports part, the boosting device of the electric rocking chair has very simple structure, has few faults when being used and the service life is greatly prolonged.

Description

Technical field [0001] The invention belongs to household items, and in particular relates to a booster device for an electric rocking chair. Background technique [0002] The rocking chair has always been favored by people as a household item. In the prior art, there is a rocking chair that uses an electric booster device to help swing. For example, Chinese patents ZL01276889.8 and ZL200710076501.8 disclose such devices. The booster devices of these rocking chairs include motors, levers, gears and other components, which are complex in structure, high in cost, prone to failure, and affect their service life. Summary of the invention [0003] The purpose of the present invention is to provide a booster device for an electric rocking chair with simple structure, few failures and long life. [0004] The technical solution adopted to achieve the objective of the present invention is: the booster device of the electric rocking chair includes a guiding insulating cylinder, a metal movi...
