Problems solved by technology

[0002] Most of the existing electric fans have exposed wings, and a net cover is added outside, which has certain potential safety hazards, especially for children to touch with fingers, or play with chopsticks and knives, which is very dangerous and may cause injury accidents
In addition, as a product, the function of the fan is often very single, usually without common functions such as timing and lighting, and the power supply usually uses 220V AC, which is often not safe enough for students

Abstract

The invention discloses a multifunctional wingless electric fan which comprises a base, a cylindrical bracket, a motor base, a motor with wind wings, an airflow pipeline and an air outlet body. The cylindrical bracket is fixed on the base and the cylindrical bracket is internally provided with the motor base; the motor with the wind wings is installed on the motor base and the cylindrical bracket is communicated with an air outlet cavity in the air outlet body through the airflow pipeline; and the air outlet body is provided with an airflow outlet. The multifunctional wingless electric fan has the characteristics of safety and reliability, a plurality of functions such as illumination, time telling, ventilation and the like, strong practical applicability, particular suitability for school lives of students in middle and primary schools and the like.

Description

technical field [0001] The invention relates to an electric fan, in particular to a multifunctional wingless electric fan. Background technique [0002] Most of the existing electric fans have exposed wings, and a net cover is added outside, which has certain potential safety hazards, especially for children to touch with fingers, or play with chopsticks and knives, which is very dangerous and may cause injury accidents . In addition, as a product, the fan has a single function, and usually does not have common functions such as timing and lighting, and the power supply usually uses 220V AC, which is often not safe enough for students. Contents of the invention [0003] The object of the present invention is to provide a multifunctional wingless electric fan which is safe and reliable, has multiple functions such as lighting, time telling, ventilation, etc., has strong practicability, and is especially suitable for primary and middle school students to use in their st...
