Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when we use it, the fan blades often cannot rotate, and we need to rotate the fan blades by hand or with auxiliary tools before they can rotate. It is because the lubricating oil on the bearing of the electric fan solidifies and dries out due to the high temperature during long-term use, which makes the shaft unable to rotate and causes the motor to be easily burned

Abstract

The invention discloses a household electric fan rotating head and a using method thereof. The electric fan rotating head comprises a shell; a motor is mounted in the shell; a rotating shaft is mounted at one end of the motor; a baffle is installed on the shell; a bearing is mounted on the baffle; the bearing is an oil-retaining bearing of a traditional fan; the bearing and the rotating shaft areon the same axis; one end of the rotating shaft penetrates through the bearing and is provided with fan blades; a round hole is formed in the outer ring of the bearing; a second sponge pad is installed in the round hole; the second sponge pad is connected with a first conveying pipe; and the first conveying pipe is installed at the bottom end of one side of a storage box. According to the household electric fan rotating head and the using method thereof of the invention, a T-shaped pressing plate slowly moves downwards, so that lubricating oil is slowly extruded, and therefore, the lubricatingoil slowly enters the second sponge pad from the first conveying pipe; and the rotating shaft is tightly attached to one side of the second sponge pad, the lubricating oil on the second sponge pad can be uniformly smeared on the rotating shaft when the rotating shaft rotates, and therefore, a lubricating property is improved, and the fan blades are prevented from failing to rotate.

Description

[0001] This application is a divisional application with the application date of August 21, 2018, and the application number CN201810955235.4, whose invention name is a rotary head of a household electric fan. technical field [0002] The invention relates to the technical field of household appliances, in particular to a household electric fan rotary head and a method for using the same. Background technique [0003] Electric fans are one of the most commonly used appliances in household appliances. Although air-conditioning fans are slowly being used, traditional fan blades are still the mainstream. [0004] When we use it, the fan blades often cannot rotate. We need to turn the fan blades by hand or with auxiliary tools before they can rotate. It solidifies and dries up, causing the shaft to be unable to rotate, causing the motor to be easily burned. Contents of the invention [0005] The purpose of the present invention is to solve the shortcomings in the prior art, s...
