Problems solved by technology

[0003] However, the existing ceiling fans are all adjusted by adjusting the speed when the wind is adjusted. When the speed is fast, the wind is also strong, but it also increases the degree of danger. It is very dangerous if it falls or comes into contact with the fan at this time.

Embodiment Construction

[0011] The structure, principle, etc. of the present invention are further described below; the present invention only lists exemplary embodiments, and those skilled in the art can recognize that, based on the following embodiments, the present invention can also make some changes or transformations, any changes or Transformations all fall within the protection scope of the present invention without departing from the principle of the present invention.

[0012] Examples such as figure 1 As shown, a ceiling fan with an adjustable fan blade angle includes a motor 1, and a plurality of fan teeth 3 whose angles can be adjusted are arranged in a circular array on the outer circumference of the motor 1.

[0013] An inner ring 5 is fixedly mounted on one end of each sector tooth 3 close to the motor 1 .

[0014] Outer rings 2 used in conjunction with the inner ring 5 are respectively fixedly installed on the outer circumference of the motor 1 at positions corresponding to the inner...

Abstract

The invention discloses a ceiling fan with adjustable fan-blade angles. The ceiling fan includes a motor. A plurality of fan teeth capable of adjusting the angles are arranged on the outer periphery of the motor in an annular arraying mode. An inner ring is fixedly mounted at the end, close to the motor, of each fan tooth. An outer ring which is matched with the corresponding inner ring to be usedis fixedly mounted at the position, corresponding to the corresponding inner ring, of the outer periphery of the motor. A plurality of holes are formed in each outer ring. Holes are further formed inthe positions, corresponding to the corresponding holes of each outer ring, of each inner ring. When the holes in the inner rings and the outer rings are on the same axis, a fixing pin can be inserted. According to the ceiling fan with the adjustable fan-blade angles, by arranging the fan teeth capable of adjusting the angles, the wind volume can be adjusted without changing the rotating speed, meanwhile, the high wind volume can be output at the low rotating speed, and the dangerous index because of contacting with the fan is reduced.

Description

technical field [0001] The invention belongs to the technical field of home appliances, and in particular relates to a ceiling fan with adjustable blade angles. Background technique [0002] Ceiling fan is a common household appliance for people to cool down and relieve summer heat. It not only adopts a healthy heat dissipation method, but also has low energy consumption and is environmentally friendly and pollution-free. [0003] However, existing ceiling fans are all finished by adjusting the rotating speed when adjusting the wind size. The faster the rotating speed, the stronger the wind, but also increased the degree of danger. It is very dangerous if it falls or contacts with the fan at this time. Contents of the invention [0004] In order to solve the above-mentioned problems in the prior art, the present invention provides a ceiling fan with low rotation speed and large air volume and adjustable blade angle. [0005] In order to solve the above-mentioned problems,...
