Problems solved by technology
[0003] The disadvantages of using the blow-suction conversion structure of the blower are: there is air leakage between the conversion structure and the casing, and there is a large wind loss; and the efficiency of the motor is not maximized.
The main disadvantage of the method of realizing different functions by replacing the blowing and absorbing parts is that it is cumbersome for the operator to replace the accessories, and the replaced accessories are inconvenient to store and easy to lose.

Embodiment Construction
[0053] see figure 1 , figure 2As shown, the blower 1 includes a main body casing 2 , an operating handle 5 disposed on the main body casing 2 , and a blowing and absorbing member 10 detachably connected to the main body casing 2 . Wherein, a motor 3 is arranged in the main body casing 2, and a motor output shaft 3a extending longitudinally is driven by the motor 3, and a first impeller 4 and a second impeller 14 are arranged on the output shaft 3a. The blowing and absorbing part 10 is detachably connected to the main body casing 2. The blowing and absorbing part 10 in this embodiment includes an independent dust suction pipe 11 and an air blowing pipe 12. The extension direction of the dust suction pipe 11 and the blowing pipe 12 are consistent and opposite to each other. Fixed setting, of course, the two can also be integrally formed. Dust suction pipe 11 is positioned at the top of blowing pipe 12, and blowing pipe 12 is provided with blowing passage and is provided with ...

The invention discloses a blowing and sucking machine which comprises a main machine casing, a blowing and sucking accessory, an operating handle, a motor, an output shaft and a control mechanism, wherein the blowing and sucking accessory is connected inside the main machine casing, the operating handle and the motor are arranged in the main machine casing, the output shaft is driven by the motor, and the control mechanism controls the motor to rotate; an air inlet and a dust outlet are formed in the main machine casing; a first impeller and a second impeller are arranged on the output shaft; when the blowing and sucking machine is in a blowing mode, the first impeller rotates, and air current enters from the air inlet and is discharged from the blowing and sucking accessory; when the blowing and sucking machine is in a sucking mode, the second impeller rotates, and air current enters from the blowing and sucking accessory and is discharged from the dust outlet; and the first impeller and the second impeller rotate in opposite directions. The blowing and sucking machine is high in blowing and sucking efficiency, labor-saving and convenient to operate.
Description
technical field [0001] The invention relates to a hand-held operating device, in particular to a portable blower. Background technique [0002] Blowing machines that are often encountered in the market usually use a fan to realize the three-in-one function, that is, the fan should be suitable for working in both the blowing mode and the suction mode. To have a crushing function. The blower with a single fan mainly relies on the following two schemes to perform blowing and suction switching. One is to set a blowing and suction switching mechanism so that the operator can manually control the switching mechanism to change the internal air duct structure of the blowing and suction machine; The first is to convert the blowing machine into a blowing machine or a suction machine by replacing the blowing and absorbing parts. [0003] The disadvantages of using the blow-suction conversion structure of the blower are: there is air leakage between the conversion structure and the ca...
