Description

energy saving fan

technical field

The utility model relates to an energy-saving fan.

Background technique

Under the international background of environmental degradation and increasingly severe energy shortage, the low-carbon concept has penetrated into all aspects of people's life and production, from home to travel without exception; thus, low-carbon energy-saving technology has become a competitive factor for most companies. On March 26, 2010, at the China Small Household Appliances Fair held at Zhongshan Huangpu International Convention and Exhibition Center, Zheng Jianzhong, general manager of Cixi Xiongsheng Electric Co., Ltd. pointed out that in terms of low-carbon energy saving, fans have also been included in the energy-saving list. Under the competition of air-conditioning products, fans were once regarded as out-of-home appliances, but this is not the case. On March 1, 2010, China's fans began to implement the energy efficiency labeling system. The implementation of this system has prompted home appliance companies to develop more energy-saving products, and promoted the competitive advantage of fans and similar functional products, and gradually tended to partially replace air conditioners. , so as to realize the "low carbon" design concept advocated by the society.

The existing fans on the market are similar in terms of structural design principles. Most of them are composed of fan blades, fan heads, governors, motors, and oscillating air supply devices. The fans are turned by turning on the power supply. The electric energy used Basically, it is obtained by thermal power generation, and the thermal energy generated by the combustion of coal, oil, natural gas and other fuels is converted into kinetic energy to produce electric energy. This process will emit a large amount of carbon dioxide and harmful gases into the air, causing great pollution to the environment. In order to solve the above problems, environmental protection energy can be used to replace the electric energy required for fan work. The Chinese patent publication number is CN2888139Y, the publication date is April 11, 2007, and the invention name is a patent for mechanical energy-saving fan. A fan that can intermittently provide external force manually can convert the conversion of electric energy and kinetic energy into the transmission of kinetic energy, but it is not very convenient to use. At present, there is no truly mature fan that uses renewable energy to completely replace electric energy to meet the real low-carbon energy-saving needs.
