Description

fan structure

The invention relates to the field of fan manufacture, in particular to a fan stator waterproof structure.

The motor stator of the fan motor is filled with glue, so that the glue can completely cover the motor stator and cure, so that the glue can protect the motor stator, achieve the effect of waterproofing, and greatly improve the reliability, so that the fan can be used in some more severe environment use.

Please refer to Figures 1A and 1B, the current fan motor stator is filled with glue, and the following steps will be performed. (The first metal mold 91, the second metal mold 92, the third metal mold 93) are fixed, and then the liquid colloid is poured into the mold, and the mold is heated to solidify the colloid. The motor stator 81 that has been filled with glue is taken out, and finally the motor stator 81 that has been covered with glue is installed on the shaft barrel 82 of the fan frame. However, this approach has the following problems.

1. The cost is high, and it is necessary to make a special glue-filling mold. In order to make the subsequent mold removal steps more smoothly, a group of molds can only be glued to one motor stator at a time, resulting in a large-scale production. mold.

2. The production efficiency is low. For each motor stator to be glued, one mold assembly and one mold removal must be performed. In order to avoid glue leakage during mold assembly, it is necessary to tighten the bolts. In addition, the steps of removing the mold after heating the colloid solidify It is very difficult, there will be a problem that the glue sticks to the mold, and it will take a lot of time to remove the bolts at the same time.

3. The defect rate is high, and the mold will gradually lose after a period of use, which will affect the glue filling process, such as colloid gaps, bubbles on the colloid surface, incomplete coating, and burrs on the finished product. When dismantling, there may be problems of colloid tearing and damage. These problems need to be dealt with by secondary processing after filling the glue. Some more serious conditions can only be discarded when they cannot be handled.

4. In an additional step, the motor stator after the rubber coating needs to be manually installed on the shaft of the fan frame, so it takes time to manually complete the combination of the motor stator and the fan frame.

Therefore, how to solve the above-mentioned problems and deficiencies is the direction that the creator of this case and the relevant manufacturers engaged in this industry are eager to research and improve.

In order to improve the above problems, the present invention provides a fan structure. By providing a motor stator casing, the traditional glue filling method using a mold is replaced, and the current glue filling problem is completely improved.

In order to achieve the above-mentioned purpose, the present invention provides a fan structure, which includes: a fan frame body with a base and a vertical shaft; a motor stator casing with a top and a bottom, the top has a shaft hole, the bottom It is in an open shape corresponding to the upper part of the cover and the groove is combined with the base, and together with the shaft barrel and the groove, a glue filling space is formed. It is communicated with the glue filling space; a motor stator is sleeved on the outside of the shaft barrel and accommodated in the glue filling space; and a glue is filled in the glue filling space and covers the outside of the motor stator at the same time.

With the above structure, many problems of traditional metal molds in gluing are completely improved, and production efficiency and product yield are greatly improved. At the same time, special gluing molds are no longer required, which reduces the overall production cost. Low, completely improve the current problem of gluing, and the overall structure has a motor stator casing as the outermost protection, providing better structural strength.
