Abstract

The invention relates to a fan. The fan comprises a spraying nozzle and a component for generating airflow passing through the spraying nozzle. The spraying nozzle comprises an inner passage, an exhaust port and a guide surface used for guiding the airflow. The spraying nozzle extends around an axis to limit an opening. The guide surface is arranged in the downstream of the exhaust port and is adjacent to the exhaust port. An intersection line formed by the guide surface and a plane where the axis is located is a straight line, and the intersection angle between the intersection line and the axis equals that between the outlet direction of the exhaust port and the axis in the extension part of the intersection line. The invention further provides the spraying nozzle for the fan.

Accompanying drawing explanation

Figure l is the front schematic view of fan of the present invention.

Fig. 2 is the side view of fan shown in Fig. 1.

Fig. 3 is that the fan shown in figure l is along the sectional view of A-A line intercepting.

Embodiment

Figure l is that Fig. 2 is the side view of the fan shown in figure l from the structural representation of the fan of the present invention of device forward observation, and Fig. 3 is the sectional view that the fan shown in figure l intercepts along A-A line.From Fig. 1 to Fig. 3, can find out, this fan comprises pedestal 1 and is arranged on the nozzle 2 on pedestal 1; Pedestal 1 comprises base portion 3 and is positioned at the main body 4 on base portion 3, and main body 4 can swing with respect to base portion 3; Main body 4 comprises the member being used to form by the air-flow of described nozzle, described member comprises impeller chimney 11, is positioned at the impeller 12 of impeller chimney and the motor 13 of drives impeller rotary work, described main body 4 comprises main body 4a and the lower main body 4b with suction port 5, and upper main body 4a can slide and make its inclination with respect to lower main body 4b; Nozzle 2 comprises inner passage 7, relief opening 8 and limits interior side body 9 and the outside housing 10 of inner passage 7 and relief opening 8, interior side body 9 comprises that guiding surface 14 that next-door neighbour's relief opening 8 arranges and next-door neighbour's guiding surface 14 arrange opens surface 15, nozzle 2 defines one and is positioned at central opening 6, and opening 6 has the axis X that is positioned at central part.

From Fig. 3, it can also be seen that, guiding surface 14 is straight line with the formed intersection of plane by axis X, and the angle between this intersection and axis X equals at the Way out of the relief opening of this intersection extended spot and the angle between axis X.In the present embodiment, this angle is 0 °, i.e. this intersection X that parallels to the axis, and the Way out of the relief opening of this intersection extended spot is identical with the direction of axis X.

Generally, this angle is set to non-zero, and the distance of the wind that its value can be exported according to fan requires to arrange.For example this angle is set to-10 °, at this moment guiding surface 14 along axis X direction tapered approach axis X.

During apparatus of the present invention work, the suction port 5 of air main body 4 enters in main body 4, the member that is used to form the air-flow by described nozzle is converted to by the air entering the air-flow that air pressure is higher, this air-flow having boosted is admitted in the inner passage 7 of nozzle 2, and the air-flow that inner passage 7 receives is launched by relief opening 8, air from fan outside is entrainmented by opening 6 by the air-flow of launching from relief opening, and the air-flow of launching from relief opening 8 forms the total air flow of output forward with the air-flow being entrainmented; The guiding surface 14 of this kind of fan guides its air-flow of launching along the Way out of relief opening 8, and the air-flow that its relief opening 8 is launched and the rubbing action between guiding surface 14 significantly weaken, and energy loss and the noise of its generation are all less.

Although shown and described and thought at present preferred embodiments of the invention, apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from scope of the present invention as defined in appended claims.
