Problems solved by technology

However, the volume of the volute of the centrifugal blower and suction machine is large, and the conversion of the blowing and suction modes is generally realized by switching the blowing and suction pipes. This requires two air pipes during actual operation, and the pipes are easy to lose, and it takes time and effort to replace them.
An axial flow blowing machine currently on sale realizes the switching of the blowing and suction mode through the forward and reverse rotation of the motor. Although only a single air duct is used, the forward and reverse structure of the motor greatly reduces the energy of the blower and suction machine. Utilization, i.e. low energy efficiency

Embodiment Construction

[0027] figure 1 The blower 100 of the first embodiment shown is an axial flow blower, figure 2 The middle blower 100 is in the suction mode, image 3 The blower 100 is in blowing mode. The air blower 100 in this embodiment is a knapsack type, and it can also be hand-held in other embodiments.

[0028] like Figure 1 to Figure 3 As shown, the blower 100 includes a carrying device 11, a housing 12, and a driving device 13; the blower 100 in the suction mode also includes a dust box 14; the blower 100 in the blower mode also includes an air inlet Net 15. The casing 12 extends along the first straight line 101. The casing 12 includes an air duct 121 for airflow, and the airflow basically flows along the first straight line 101. The air duct 121 includes a first airflow port 1214 and a second airflow port 1215. figure 1 The direction indicated by the middle arrow is the flow direction of the airflow in the suction mode, and the direction of the airflow in the blow mode is opp...

Abstract

The invention discloses a blower, which comprises: a shell, including an air pipe for forming an airflow channel, a first airflow port is formed at one end of the airflow channel, and a first airflow port is formed at the other end of the airflow channel opposite to the first airflow port. The second air outlet; the fan is arranged in the air flow channel; the motor is used to drive the fan to rotate around the first axis and along the first rotation direction; the driving device is used to drive the fan to switch between the first state and the second state; The fan has a first side and a second side located on two sides of a first plane perpendicular to the first axis, and a negative side located on the first side of the fan is formed when the fan rotates around the first axis and in a first rotation direction. A pressure zone and a positive pressure zone located on the second side of the fan; wherein, the blower has a blowing mode and a suction mode. The invention can provide an axial flow blowing machine with high energy efficiency and convenient switching between blowing and suction modes.

Description

technical field [0001] The invention relates to a garden tool, in particular to a blower. Background technique [0002] As a commonly used garden tool, the blower can help users clean up fallen leaves and dust in the garden. Existing blowing machines are divided into centrifugal blowing machines and axial flow blowing machines, mainly based on centrifugal blowing machines. However, the volume of the volute of the centrifugal blower and suction machine is large, and the switching between the blowing and suction modes is generally achieved by switching the blowing and suction pipes. This requires two air pipes during actual operation, and the pipes are easy to lose, and it takes time and effort to replace them. An axial flow blowing machine currently on sale realizes the switching of the blowing and suction mode through the forward and reverse rotation of the motor. Although only a single air duct is used, the forward and reverse structure of the motor greatly reduces the ene...
