Description

Technical Field

[0001] The utility model relates to the technical field of blowers, in particular to a large blower driven by a diesel engine. Background Art

[0002] The blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (also oil tank), and oil drip nozzle. The blower operates by the eccentric rotor offset in the cylinder, and the volume change between the blades in the rotor slot causes the air to be sucked in, compressed, and expelled.

[0003] After searching application number CN201721202790.7, a blower is found, including a blower housing, a cover and a base, the housing and the cover form a cavity, the cavity is equipped with an impeller, the base is equipped with a motor, the motor is connected to control the impeller, the housing is equipped with an air inlet, the cover is equipped with an air outlet, a filter is provided at the air inlet, and both the air inlet and the air outlet are equipped with a cover, the cover includes a cover body and a connecting end located below the cover body, an annular groove is provided on the end surface of the connecting end away from the cover body, the annular groove separates the connecting end into a central cylindrical body and an outer annular body, the outer body of the connecting end is circumferentially distributed with through holes, and balls are built into the through holes, and a compression spring is provided between the balls and the central cylindrical body. The blower has a reasonable and simple structural design, and by setting a cover connected to the inlet and outlet ends, it is easy to find the cover and is not easy to lose. At the same time, the cover is equipped with balls, which is convenient to snap on and take off, and does not damage the inlet and outlet, thereby extending the service life.

[0004] The blower in the comparative document, when in use, compresses the spring to press the ball tightly against the cover, so that the cover is closed on the air outlet for dust prevention. However, the ball is easily rolled by external force. When the cover is subjected to outward force along the air outlet, the cover is easy to slide along the side wall of the air outlet, causing the cover to detach from the air outlet, ultimately affecting the dust prevention performance of the cover.

[0005] To this end, we propose a large blower driven by a diesel engine. Utility Model Content
