Problems solved by technology

[0002] The blowing and suction machine needs to have both blowing and suction functions. In the structure of the axial flow fan blowing and sucking the same tube, one solution is to realize the forward and reverse rotation of the motor. The defect of this solution is that the suction or suction performance is weak; the other is The first solution is to switch the tuyere by rotating the motor assembly to realize the conversion of blowing and sucking, the structure is complicated and the cost is high

Embodiment 1

[0045] like Figure 1 to Figure 19 As shown, this embodiment shows a blowing-suction conversion structure for a blower-suction fan, including a casing 1 and a bracket 2, the surface of the casing 1 is provided with an air inlet 13 and an air outlet 14, and the air inlet 13 Between the air outlet 14 and the stud 41 for mounting the bracket 2, the bracket 2 is provided with a first air outlet 21 and a second air outlet 22, the bracket 2 is rotatably connected with the stud 41, and the first air outlet An air duct 8 is installed on the 21, and an air inlet cover 5 or a dust collection bag 6 is installed on the second air outlet 22. When the first air outlet 21 is connected with the air inlet 13, the blower is in a suction mode, When the first air outlet 21 is docked with the air outlet 14, the blowing and suction fan is in the blowing mode, and the bracket 2 rotates around the stud 41 to switch between the blowing and suction modes.

[0046] In this embodiment, the air inlet 13 ...

Embodiment 2

[0056] like Figures 1 to 9 As shown, this embodiment shows a blower, the blower is provided with the conversion structure of the blower as described in Embodiment 1 or other same embodiments, the casing 1 in this embodiment includes a left The casing 111 and the right casing 121, the left casing 111 and the right casing 121 are spliced ​​by screws 235, the power cord 17 is installed on the right casing 121, and the connection between the power cord 17 and the right casing 121 A power supply sheath 171 is sheathed at the center, and the casing 1 includes a handle on which a power switch 15 and a power supply pressing plate 16 are arranged. The power cord 17 is connected to the power switch 15. By pressing the power supply Pressing plate 16 just can make power switch 15 open.

[0057] The switching process of the blowing mode of the blowing fan described in this embodiment is as follows:

[0058] Suction mode: the first air port 21 is docked with the air inlet 13, the second ...

Abstract

The invention provides a blowing and suction switching structure for a blowing and suction fan and the blowing and suction fan. The blowing and suction switching structure comprises a machine shell and a support, an air inlet and an air outlet are formed in the surface of the machine shell, a stud used for installing the support is arranged between the air inlet and the air outlet, a first air opening and a second air opening are formed in the support, the support is rotationally connected with the stud, an air pipe is installed on the first air opening, and an air inlet cover or a dust collection bag is installed on the second air opening. When the first air opening is in butt joint with the air inlet, the blowing and suction fan is in an air suction mode, when the first air opening is in butt joint with the air outlet, the blowing and suction fan is in an air blowing mode, the support rotates around the stud to achieve switching of the blowing and suction modes, and air blowing and air suction modes can be replaced conveniently.

Description

【Technical field】 [0001] The invention relates to a blow-suction conversion structure for a blower-suction fan and a blower-suction fan, belonging to the technical field of blower-suction fans. 【Background technique】 [0002] The blowing and suction machine needs to have both blowing and suction functions. In the structure of the axial flow fan blowing and sucking the same tube, one solution is to realize the forward and reverse rotation of the motor. The defect of this solution is that the suction or suction performance is weak; the other is The first solution is to switch the tuyere by rotating the motor assembly to realize the conversion of blowing and suction, and the structure is complicated and the cost is high. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a blowing-suction conversion structure and a blowing-suction fan for the blowing-suction fan, which facilitates the replacement of blowing and suction mo...
