Tower fan air channel swing mechanism

Abstract

The invention relates to a tower fan air channel swing mechanism which comprises an enclosure, a control panel, a wind wheel bearing assembly, a wind wheel, an air channel, a driving motor and a base, wherein the control panel is arranged at the upper end of the enclosure; the enclosure comprises a front housing and a rear housing which are matched mutually, and the front housing is provided withan air-out grating; the upper end of the wind wheel is provided with an upper shaft, the lower end of the wind wheel is provided with a lower shaft, and the wind wheel is positioned in the air channel; the mechanism is characterized by also comprising a wabble mechanism which is installed at the upper part in the enclosure and drives the air channel to rotate; the air channel is provided with an air inlet and an air outlet; the inner side at the upper end of the air channel is provided with a front shaft hole, and the outer side at the lower end of the air channel is provided with a rear shaft hole; the wind wheel bearing assembly is installed on the upper part in the enclosure and is positioned between the air channel and the wind wheel; the upper end of the wind wheel bearing assembly is matched with the front shaft hole; the upper shaft of the wind wheel is positioned in the wind wheel bearing assembly and can rotate; the lower shaft of the wind wheel passes through the rear shaft hole, can rotate and is connected with a rotary shaft of the driving motor; and the enclosure is fixed on the base. According to the invention, the connection distance of the wabble mechanism and the air channel is reduced greatly, the reliability is improved, the line length between the wabble mechanism and the control panel is shortened, the air channel and the wind wheel bearing assembly are optimized, and the cost is lowered.

Description

technical field [0001] The invention relates to a tower fan air duct rotation mechanism, in particular to an air duct rotation mechanism for a cross-flow tower fan. Background technique [0002] There are three types of tower fan oscillating air supply mechanisms in the market: one is that the fuselage oscillates relative to the base. Body weight, long-term use and reliable travel, and the rotation of the entire body is prone to external resistance interference, which affects safety, and the long-term torsional wear of the power cord also poses safety hazards. The second type is a mechanism that rotates the air duct inside the tower fan to control the air supply. However, such products currently on the market fix the swing mechanism at the lower end of the wind wheel and behind the motor. The connection span between the swing mechanism and the air duct is long and the strength is low. , poor reliability, and due to the long arm and poor structural strength, it can only be d...

[0002] There are three types of tower fan oscillating air supply mechanisms in the market: one is that the fuselage oscillates relative to the base. Body weight, long-term use and reliable travel, and the rotation of the entire body is prone to external resistance interference, which affects safety, and the long-term torsion and wear of the power cord also poses safety hazards

The second type is a mechanism that rotates the air duct inside the tower fan to control the air supply. However, such products currently on the market fix the swing mechanism at the lower end of the wind wheel and behind the motor. The connection span between the swing mechanism and the air duct is long and the strength is low. , poor reliability, and due to the long arm and poor structural strength, it can only be designed as an air duct assembly; also because the control panel is on the top of the fuselage, and the synchronous motor is at the bottom of the fuselage, so there must be a long connecting line running through the fuselage Connection, unreasonable structure, high cost of line length

The three existing tower fan ducts on the market are the components of the duct main body and the duct shaft. The front end of the duct is fixed by the duct shaft and the wind wheel bearing assembly. Wheels cannot share one bearing assembly, which is costly
