Problems solved by technology

[0003] At present, the push rod vacuum cleaner is mainly cleaned by the floor brush. When it is necessary to switch to the vacuum tube for free mode cleaning, such as cleaning the small area behind the sofa or the home, it is necessary to clean the connecting tube on the entire floor brush. The work can only be continued after disassembly and replacement of the vacuum tube, so it is not convenient to use and reduces the user experience

Embodiment 1

[0027] see Figure 1 to Figure 4 , the figure shows a self-switching air duct push rod vacuum cleaner provided by an embodiment of the present invention, which includes a vacuum cleaner main body 1, a floor brush component 2, a first dust pipe 3 and a second dust pipe 4, the first dust pipe The pipe 3 is connected to the dust collection part, the second dust pipe 4 is connected to the ground brush part 2, and a dust pipe switching mechanism 5 is fixedly installed on one side of the vacuum cleaner host 1, and the dust pipe switching mechanism 5 includes a switching seat 51, which is cylindrical. There is a circular cavity 52 inside, the axial direction of the circular cavity 52 is perpendicular to the axial direction of the first dust pipe 3 or the second dust pipe 4, and the switching seat 51 is provided with a first interface 53, a second interface 54 and The third interface 55, the first interface 53 and the second interface 54 are arranged coaxially, the third interface 55 ...

Embodiment 2

[0032] see Figure 1 to Figure 2 , the figure shows a self-switching air duct push rod vacuum cleaner provided by Embodiment 2 of the present invention. On the basis of the above embodiment, this embodiment further makes the following technical solutions as improvements: switch port Two arc-shaped end faces 562 are respectively formed at the opposite ends of the 561, which can reduce the wind resistance in the air duct and improve the dust collection efficiency.

Embodiment 3

[0034] see Figure 1 to Figure 2, the figure shows a self-switching air duct push rod vacuum cleaner provided by Embodiment 3 of the present invention. On the basis of the above embodiment, this embodiment further makes the following technical solutions as improvements: active switching The pipe 56 is provided with a dust guide plate 57 that can slide along the circumferential direction of the movable switching pipe 56. The dust guide plate 57 is specifically a triangular plate body with a hollow structure inside. One end 571 is sleeved on the side wall of the movable switching tube 56 , the second end 572 of the dust guide plate 57 extends into the movable switching tube 56 , and the second end 572 forms a U-shaped bend.

[0035] Through the setting of the above structure, the dust can be quickly guided in the movable switching pipe along the circumferential direction of the movable switching pipe, thereby improving the dust collection efficiency. In order to best improve th...

Abstract

The invention provides a push rod type dust collector capable of automatically switching air ducts and an air duct switching method. The push rod type dust collector comprises a dust collector main machine, a ground brush component, a first dust pipe and a second dust pipe, a dust pipe switching mechanism is fixedly installed on one side of the dust collector main machine, the dust pipe switchingmechanism comprises a switching base, a circular cavity is formed in the switching base, and a first connector, a second connector and a third connector are arranged on the switching base; and a cylindrical movable switching pipe capable of rolling in the circumferential direction of the circular cavity is arranged in the circular cavity, the interior of the movable switching pipe is of a hollow structure, a switching opening which is half of the perimeter of the movable switching pipe is formed in the side wall of the movable switching pipe, and the movable switching pipe rotates back and forth between the first connector and the second connector. The invention further provides an air duct switching method. Compared with the prior art, automatic switching of the air ducts of the dust suction pipe can be achieved, and the use convenience is improved.

Description

technical field [0001] The invention relates to a push rod type vacuum cleaner, in particular to a push rod type vacuum cleaner with self-switching air duct and a method for switching the air duct. Background technique [0002] The push rod vacuum cleaner is a kind of upright vacuum cleaner. Push rod vacuum cleaners are mainly composed of three parts: dust collection, dust collection, and dust filtration, generally including series commutator motors, centrifugal fans, dust filters and dust collection accessories. [0003] At present, the push rod vacuum cleaner is mainly cleaned by the floor brush. When it is necessary to switch to the vacuum tube for free mode cleaning, such as cleaning the small area behind the sofa or the home, it is necessary to clean the connecting tube on the entire floor brush. The work can only be continued after disassembly and replacement of the vacuum tube, which is inconvenient to use and reduces the user experience. Contents of the invention ...
