In the cavity, avoid placing it in the air flow channel formed between the first shell part 31 and the second shell part 32 to facilitate smooth gas flow.
  • the structure of the motor in the present invention includes two separate assemblies, namely the casing 30 and the guide vanes 40.
  • the original casing which has a complex blade structure and is difficult to make, is divided into two easy-to-process parts, so that the blade form is simplified, that is, in The first blade 33 is provided on the casing 30 and the second blade 42 is provided on the guide vane 40.
  • the two components can be easily processed through CNC machine tools, molds, etc., effectively controlling the production cost, and after combination, the airflow It is not easy to form gas separation or turbulence, which improves the efficiency of the motor.
  • the blower in the present invention can be used in small blowing household appliances such as hair dryers and small fans to flow gas out of the household appliances at a reasonable flow rate and direction.
  • the motor and hair dryer of the present invention have the following advantages: by optimizing the mode of the guide vane 40, the guide vane 40 is nested in the middle on the inner frame of the motor housing, and the outer edge of the guide vane 40 is connected to the inner frame of the motor housing.
  • the motor casing is connected so that the guide vane 40 and the casing 30 form a whole, and the blades of the guide vane 40 are relatively fixed to the motor casing, which increases the resonance frequency and avoids the resonance zone, which can effectively reduce noise and extend the life of the motor. Broad application prospects.

Abstract

L'invention concerne un support de ventilateur (10), un moteur électrique et une soufflante. Le support de ventilateur (10) est approprié pour être emmanché sur un côté externe d'un ventilateur. Le support de ventilateur (10) comprend : un manchon (1), comprenant une partie d'adaptation (11) et une partie de guidage d'écoulement (12) reliée à la partie d'adaptation (11), la partie d'adaptation (11) étant appropriée pour être emmanchée sur le côté externe du ventilateur, et la partie de guidage d'écoulement (12) étant pourvue d'une première extrémité (123) proche de la partie d'adaptation (11) et d'une seconde extrémité (124) à l'opposé de la partie d'adaptation (11) ; et une partie de support (2) qui est disposée à proximité de la première extrémité (123) et qui est appropriée pour venir en butée contre une extrémité du ventilateur. La partie d'adaptation (11) peut empêcher que le ventilateur soit directement et rigidement relié à d'autres composants, de telle sorte que les vibrations et le bruit du ventilateur sont réduits. La partie de support (2) peut non seulement augmenter la surface de contact entre le ventilateur et celle-ci, ce qui permet de réduire davantage les vibrations et le bruit générés par le ventilateur, mais permet également que le ventilateur soit relié de manière plus stable au manchon (1), et l'effet de réduction de bruit peut également être obtenu. Le moteur électrique comprend une coque (30) et une aube de guidage (40), la coque (30) comprenant une première partie de coque (31), une seconde partie de coque (32), et une pluralité de premières aubes (33) reliées et fixées à la première partie de coque (31) et à la seconde partie de coque (32), et un canal d'écoulement d'air étant formé entre la première partie de coque (31) et la seconde partie de coque (32) ; et l'aube de guidage (40) comprenant une partie corps principal (41) et une pluralité de secondes aubes (42) reliées à demeure à la partie corps principal (41), et la partie corps principal (41) étant emboîtée dans une bague externe de la seconde partie coque (32). L'aube de guidage (40) est fixée à la coque (30), et les extrémités des secondes aubes (42) à l'opposé de la partie corps principal (41) sont reliées à demeure à une paroi interne de la première partie coque (31). En optimisant le mode de l'aube de guidage (40), les secondes aubes (42) de l'aube de guidage (40) sont relativement fixées à la coque (30) du moteur électrique de façon à améliorer la fréquence de résonance et à éviter une bande de résonance, ce qui permet de réduire efficacement le bruit et de prolonger la durée de vie du moteur électrique.
