In addition, the motor of this application has two kinds of heat dissipation modes, under the condition of normal drying, adopt as shown in fig. 2 the mode, this moment, second bar ventilation hole and the third bar ventilation hole intercommunication that corresponds, consequently, the air current that radiator fan produced directly passes inside the motor, and the radiating air current blows up the articulated slab, thereby give vent to anger from first bar ventilation hole, as shown in fig. 3, the one end far away apart from the centre of a circle of articulated slab is opened, and the first arc ventilation hole of first end cover department is located the position far away from the centre of a circle, thereby be favorable to more giving vent to anger from the radiating air current that first bar ventilation hole came out, bar plane board butt radiating fin this moment, radiating fin plays natural heat dissipation's effect. Under the great condition of external dust or humidity, shorten through control electric putter, under the effect of extension spring, it rotates to rotate the ring, as shown in fig. 9, thereby make second bar ventilation hole shielded, but inlet channel and the air outlet channel intercommunication that corresponds, therefore the air current that radiator fan produced, can pass through inlet channel and air outlet channel, and bar plane board this moment is by the driving lever butt, thereby two adjacent radiating fin and the bar plane board that corresponds form a shrouded radiating channel, thereby the radiating air current that comes out from air outlet channel can circulate along this radiating channel fast and take away the heat, thereby the radiating air current does not pass through inside the motor, play fine dustproof and waterproof effect, but because the radiating air current between the radiating fin, and the radiating air current is restricted in radiating channel, thereby the radiating air current can flow through whole radiating channel, thereby form fine radiating effect. Avoid under the condition that does not have the bar flat panel, the heat dissipation air current can be diverged to the outside to lead to being close to the heat of the radiating fin department of first end seat position and being difficult to being taken away, consequently, still can play fine radiating effect through this kind of mode. The switching between the two heat dissipation modes can be manually realized, or can be automatically controlled by using the control unit according to the temperature and humidity information, for example, when the humidity is greater than or equal to a humidity set threshold, the motor always dissipates heat by using the strip heat dissipation channel surrounding the housing, as shown in fig. 9, the first strip ventilation hole and the second strip ventilation hole are both in a closed state; when the humidity is smaller than the humidity setting threshold, if the temperature is larger than or equal to the temperature setting threshold, as shown in fig. 2, the heat is dissipated by directly passing the heat dissipation airflow through the interior of the motor, and at the moment, the heat dissipation airflow passes through the interior of the motor, so that the heat dissipation effect is better; if the temperature is lower than the temperature setting threshold, as shown in fig. 9, the heat is dissipated by the way that the heat dissipation airflow flows through the strip-shaped heat dissipation channel, so that the waterproof and dustproof effects are good.
While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
