Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a hand-held fan and its control method. By adding a human body induction module to the fan guard part, the temperature change in the air supply area can be monitored in real time, and a reasonable control method can be used to realize the automatic operation of the fan. The existing mechanical operation of hand-held fans makes the user experience poor

Abstract

The invention discloses a handheld fan and a control method thereof. The fan comprises a human body induction module arranged on a net cover for coating fan blades, and further comprises a controllerelectrically connected with the human body induction module and a fan motor electrically connected with the controller. The method comprises the following steps: when the fan is in a working state, the controller receives a temperature of an air supply area detected by the human body induction module; the received temperature is compared with a preset temperature threshold to judge existence of users; and when no user exists, the fan is controlled to stop rotating. The handheld fan and the control method thereof can realize automatic startup and stop and automatic air speed adjustment, can automatically identify the existence of the users, can realize stop when the users walk away, achieves energy conservation and emission reduction, prolongs the service life, achieves the product intelligence, and improves the user experience.

Description

technical field [0001] The invention relates to household appliances, in particular to a hand-held fan and a control method thereof. Background technique [0002] Most of the hand-held fans on the market today are mechanically controlled, requiring users to manually turn them on and off to adjust the wind speed. The user experience is not good, and when the user leaves, the fan continues to run, which wastes energy. Long-term, this will affect the life of the whole machine. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hand-held fan and its control method. By adding a human body induction module to the fan guard part, the temperature change in the air supply area can be monitored in real time, and a reasonable control method can be used to realize the automatic operation of the fan. The mechanical operation of the existing hand-held fan makes the user experience poor. [0004] In order to solve the problems ...
