Blade-free fan

Abstract

The invention relates to the technical field of fans, in particular to a blade-free fan which comprises a base used for generating airflow and an air outlet device used for spraying the airflow and provided with an air outlet at the front end, wherein the base comprises a rotating part used for generating an airflow and a fixing part arranged at the bottom of the rotating part and used for driving the rotating part to horizontally rotate; the rotating part comprises a rotating housing connected with an air outlet device as well as a worm wheel and a motor which are arranged in the rotating housing, wherein the worm wheel is driven by the motor to rotate, the side wall of the rotating housing is provided with an air inlet; the fixing part comprises a fixing housing and a synchronous driving mechanism arranged at the top of the fixing housing and used for driving the rotating housing to horizontally rotate; and the fixing housing is provided with a touch screen control device. The touch screen control device is arranged at the fixing part without rotating due to the change of an air blowing angle, thus the blade-free fan is convenient for the operation of a user, ensures a good signal receiving effect of the touch screen control device, and has the advantages of simpleness in operation, convenience for use and strong practicability.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a bladeless fan. Background technique [0002] A traditional fan is composed of a fan frame, a driving motor installed in the fan frame, and fan blades rotatably connected to the driving motor. For the safety of the fan, a protective cover is usually installed on the air outlet of the fan. There are many openings on the protective cover of this fan, which is easy to hurt the fingers of children, and there is a certain degree of danger; moreover, this fan uses blades to cut the wind, and when the wind blows to the human body, it will produce a severe wind sensation The impact and the wind are not stable enough, which makes people feel uncomfortable; in addition, the blade fan needs to be disassembled, cleaned, reinstalled and inspected in daily life, which is very inconvenient.

AI Technical Summary

Problems solved by technology

There are many openings on the protective cover of this fan, which is easy to hurt the fingers of children, and there is a certain degree of danger; moreover, this fan uses blades to cut the wind, and when the wind blows to the human body, it will produce a severe wind sensation The impact and the wind are not stable enough, which makes people feel uncomfortable; in addition, the blade fan needs to be disassembled, cleaned, reinstalled and inspected in daily life, which is very inconvenient

[0003] In order to solve the above-mentioned problems, people have designed a kind of concealed blade type electric fan, and this electric fan comprises fuselage, and the front end that communicates with fuselage has the air outlet device of air outlet, and fuselage comprises fuselage shell, is located at fuselage shell The fan blade and the motor inside, the fan blade is driven by the motor to rotate, and the body shell is provided with an air inlet. The fan does not need blades, but the fan can only play the role of promoting air flow. Its single function is difficult to meet the pursuit of modern people. The multi-purpose requirements of one machine, the practicality is not strong

In addition, the control button of the electric fan in the prior art is generally arranged on the body shell, and the control button rotates with the rotation of the body shell during use, which is not conducive to adjusting the number of air outlets of the fan and turning the fan on or off. , inconvenient to use
