Description

An electric fan blade automatic dust removal device

technical field

The utility model belongs to the technical field of cleaning and dust removal, in particular to an automatic dust removal device for electric fan blades.

Background technique

Along with the raising of people's living standard, electric fan has become the necessary living electrical appliance of household. When the blades of the electric fan rotate at high speed, they rub against the air to generate electricity, so that the blades carry a large amount of static charge. Due to the adsorption of static charges, a large amount of dust in the air falls on the blades. After a period of time, the dust on the blades will become Obviously, especially for electric fans with white blades, and its impact on aesthetics. The outside of the blades are covered by a fine fan blade cover, and the front and back of the fan blade cover are fixed with screws, which is difficult to clean and brings great difficulties to people's lives.

Utility model content

In order to solve the above-mentioned technical problems, the utility model proposes an automatic dust removal device for electric fan blades.

The technical scheme of the utility model is: an electric fan blade automatic dust removal device, including interconnected storage batteries, dust detection devices and motors, a large gear driven by the motor is arranged above the motor, and a large gear is arranged around the large gear. There is at least one matching pinion, the outer surface of the pinion is provided with a vertically fixed thin column, the thin column is provided with a telescopic rod, and the end of the telescopic rod is provided with a cleaning brush.

The telescopic rod is an adjustable length telescopic rod.

The cleaning brush is a detachable cleaning brush.

The motor drives the bull gear through the shaft of the bull gear.

There are 3 small gears matching it around the bull gear.

The adjustable length telescopic rod is connected with the dust detection device.

The technical effect of the utility model is: when the blade stops, the amount of dust is automatically detected according to the dust detection system, the motor starts to work, the motor drives the rotating shaft of the large gear to rotate, the large gear drives the small gear to rotate, and the thin column forms a circle on the small gear Movement, the thin column drives the telescopic rod to move on the blade; the telescopic rod effectively saves space. Using the principle of leverage, the head end of the telescopic rod is connected to the end of the runner. Under the condition of a certain radius of the pinion, the movement of the cleaning brush is maximized. Covered area; the telescopic rod is controlled by the dust detection system, and under the condition of a certain movement range, the area of the blade can be cleaned to the greatest extent; the thin column connects the pinion and the telescopic rod to isolate the pinion and the telescopic rod to a certain extent Direct contact avoids the interference caused by the collision between the pinion gear and the telescopic rod when it rotates to the running-in position of the gear when it is directly fixed.

Detailed ways

The utility model will be further described in detail below in conjunction with the embodiments and accompanying drawings, but the implementation of the utility model is not limited thereto.

As shown in Figure 1, an electric fan blade automatic dust removal device includes an interconnected battery, a dust detection device 9 and a motor 7, the battery, the dust detection device 9 and the motor 7 are arranged on the shaft casing 2 of the electric fan, and the battery is not shown, but it can be placed in an empty position on the rotating shaft casing 2 of the electric fan, and a large gear 8 driven by it is provided above the motor 7, as shown in Figure 3, at least one and The matching pinion 5, as shown in Figure 4, the outer surface of the pinion 5 is provided with a vertically fixed thin column 6, the thin column 6 is provided with a telescopic rod 3, and the end of the telescopic rod 3 is provided with Cleaning brush 4, the brush head of cleaning brush 4 contacts with the blade 1 of electric fan.

The telescopic rod 3 is an adjustable length telescopic rod.

The cleaning brush 4 is a detachable cleaning brush.

The motor 7 drives the bull gear 8 through the shaft 10 of the bull gear.

Described bull gear 8 is provided with 3 small gears 5 that match it, and the number of gears can be determined according to the cleaning situation.

As shown in Figure 2, when the electric fan blades are rotating, the telescopic rod 3 does not work, the telescopic rod 3 shrinks, and is indented close to the edge of the casing 2, and the cleaning brush 4 is a detachable cleaning brush, which can be used when the electric fan stops working. And when there is no dust, choose to install or disassemble for cleaning.

The working state of the dust detection system 9 is determined by the blade 1 . The dust detection system 9 is provided with a sensing device, which transmits the information of the blade rotation to the dust detection system 9 . The internal structure of the dust detection system 9 is prior art.

When the blade 1 rotates, the dust detection system does not work; when the blade 1 stops, the dust detection system 9 starts to work, automatically detects the amount of dust on the blade 1, and maintains the original state when the amount of dust detected does not exceed the set value. When it is detected that the amount of dust exceeds the set value, the motor 7 is started and powered by a storage battery. The motor 7 drives the rotating shaft 10 of the large gear to rotate, and then the large gear 8 rotates. Through the gear transmission, it drives the rotation of the three small gears 5. The rotation of the small gear 5 drives the thin column 6 to perform circular motion. The head end of the telescopic rod 3 is perpendicular to the thin column 6. Fixed, the dust detection system 9 controls the telescopic rod 3 to extend, and then the telescopic rod 3 fixed on the thin column moves. The dust detection system 9 controls the telescopic rod 3 to stretch out a certain length, and the cleaning brush 4 at the end of the telescopic rod 3 moves on the blade to achieve the purpose of cleaning.

The above description is only the preferred solution of the utility model, not as a regulation of the utility model, and all the various improvements made by using the utility model description or drawings are within the protection scope of the utility model.
