TECHNICAL FIELD

[0001] The utility model belongs to the technical field of hanging neck fan, especially relates to a voice hanging neck fan. BACKGROUND

[0002] In recent years, people pursue more convenient life, in order to meet the needs of outdoor activities or other life scenes to use fan, there are all kinds of portable fans on the market, for example, hanging neck fan. The emergence of hanging neck fan solves the activity limitation brought by handheld fan, whether it is sports, outdoor activities or office use scene, hanging neck fan can free the hands of users, and handheld can realize blowing effect anytime and anywhere. For example, the Chinese patent with application No. 202022210032.8 discloses a hanging neck fan, and the hanging neck fan has four fan assemblies, so that the neck of the user can be cooled all-round.

[0003] But the above-mentioned similar hanging neck fan generally adopts physical key control system, that is, one key controls the switch of four fan assemblies, cannot be controlled individually, and there is significant human-computer interaction bottleneck in dynamic use scene. Especially in the scene of riding, climbing and other hands limited, users need to interrupt the current activity to operate the equipment, which affects the operation safety and reduces the user experience continuity. UTILITY MODEL CONTENT
