Technical Field

[0001] The utility model relates to the technical field of ceiling fans, in particular to an improved industrial large ceiling fan. Background Art

[0002] As we all know, fans are one of the most common household appliances. Depending on the usage environment, the most common fans are floor fans and ceiling fans. Among them, ceiling fans are widely used due to their strong wind power.

[0003] A ceiling fan is an electric fan fixedly mounted on the ceiling. It has many advantages such as energy saving, convenience, and practicality, and is widely loved by consumers. In traditional ceiling fans, the main shaft of the motor is connected to the lower end of the hanging head through a thread, and the upper end of the hanging head is connected to the hanging rod, and fasteners are used to penetrate the hanging head and the hanging rod. In this way, one end of the hanging head is connected to the main shaft of the motor, and the other end is connected to the hanging rod, so as to achieve the connection between the hanging rod and the main shaft of the motor. However, during the use of traditional ceiling fans, there is a lot of noise. In addition to the loud wind noise during operation, various abnormal noises are often heard from the inside of the ceiling fan. Generally, there is no problem, but when this type of ceiling fan is used in schools, libraries and other environments, it will produce many adverse effects. Therefore, it is necessary to make many improvements to the existing ceiling fans. Utility Model Content

[0004] Therefore, in view of the above problems, the utility model proposes an improved industrial large ceiling fan with reasonable structure, reduced operating noise and extended service life.

[0005] To solve this technical problem, the utility model adopts the following solution: an improved industrial large ceiling fan, comprising a connecting column, an outer shell, an upper end cover, a lower end cover, a driving mechanism, a rotating disk and a fan blade bracket; the upper end cover and the lower end cover are respectively arranged on the upper and lower ends of the outer shell, the outer shell is a hollow cylinder, the lower end of the connecting column is connected to the upper end surface of the upper end cover, the driving mechanism is arranged in the outer shell and the output end of the driving mechanism passes through the lower end cover and is connected to the rotating disk to drive the rotating disk to rotate, the fan blade bracket is arranged on the free end surface of the rotating disk, a sound insulation and heat dissipation mechanism is provided between the outer shell and the driving mechanism, the sound insulation and heat dissipation mechanism comprises an annular columnar mounting seat, a plurality of vertically arranged accommodating cavities are evenly distributed on the annular columnar mounting seat, each accommodating cavity is filled with fan coolant or sound insulation filler, and the fan coolant and the sound insulation filler are alternately distributed.

[0006] As a further improvement, the upper end cover is provided with an air vent at the top of the fan coolant receiving chamber.

[0007] As a further improvement, the driving mechanism includes a permanent magnet motor.

[0008] As a further improvement, the driving mechanism further includes a planetary reduction mechanism, and the permanent magnet motor is connected to the rotating disk via the planetary reduction mechanism to drive the rotating disk to rotate.

[0009] As a further improvement, the circumference of the lower end cover extends downward to form an annular boss, and the upper circumference of the rotating disk is rotatably sleeved on the annular boss of the lower end cover via a rotating support bearing.

[0010] By adopting the above-mentioned technical scheme, the beneficial effects of the utility model are as follows: by arranging a sound insulation and heat dissipation mechanism between the driving mechanism and the shell of the large industrial ceiling fan, that is, a plurality of vertically arranged accommodating chambers are evenly distributed on the annular columnar mounting seat, each accommodating chamber is filled with fan coolant or sound insulation filler respectively, and the fan coolant and the sound insulation filler are alternately distributed, so that the noise and abnormal sound generated by the operation of the fan driving mechanism are greatly reduced and eliminated by the sound insulation filler, and the heat generated by the driving mechanism can be quickly removed by arranging the fan coolant, thereby extending the service life, the motor adopts a higher speed motor, and the heat dissipation effect is enhanced by arranging air holes, and a permanent magnet motor plus a planetary reduction mechanism is adopted to drive the rotating disk to rotate and then drive the fan blade bracket to rotate to blow air, so that the motor has low cost, small size and light weight, and by adding a rotating support bearing between the rotating disk and the lower end cover, the fan runs more smoothly and has better force, which can be widely promoted and applied.
