Leaf suction machine and blowing and sucking machine
The invention discloses a leaf suction machine and a blowing and sucking machine. The leaf suction machine comprises a leaf suction pipe and a draught fan assembly; a leaf suction channel is defined in the leaf suction pipe, and the leaf suction channel is provided with a leaf suction port, a leaf outlet and a drainage port located between the leaf suction port and the leaf outlet; the draught fanassembly is arranged on the outer side of the leaf suction pipe, and the draught fan assembly comprises an air duct component and a wind wheel; the air duct component defines an air outlet duct, theair duct is provided with an air inlet and an air outlet, and the air inlet is in communication with the outside atmosphere; the wind wheel is rotatably arranged in the air duct so as to drive air toflow from the air inlet to the air outlet, and the air outlet is in communication with the drainage port so as to spray ejection airflow into the leaf suction channel; and the ejection airflow is usedfor driving impurities to be sucked into the leaf suction channel through the leaf suction port and flow to the leaf outlet, wherein the flow speed of the ejection airflow is larger than 40 m/s. Theleaf suction machine is light in weight, small in size and convenient to operate.
本发明公开了一种吸叶机和吹吸机，所述吸叶机包括：吸叶管，所述吸叶管内限定出吸叶通道，所述吸叶通道设有吸叶口、出叶口以及位于所述吸叶口和所述出叶口之间的引流口；风机组件，所述风机组件设于所述吸叶管的外侧，所述风机组件包括风道部件和风轮，所述风道部件限定出风道，所述风道具有进风口和出风口，所述进风口连通外界大气，所述风轮可转动地设于所述风道内以驱动空气由所述进风口朝向所述出风口流动，所述出风口与所述引流口连通以朝向所述吸叶通道内喷射引射气流，所述引射气流用于带动杂物通过所述吸叶口吸入所述吸叶通道内并流向所述出叶口，所述引射气流的流速大于40m/s。根据本发明实施例的吸叶机重量轻、体积小，操作方便。
