Detailed Description
For a better understanding of the objects, structure and function of the utility model, a cleaner head according to the utility model will be described in more detail with reference to the accompanying drawings.
As shown in figure 1, the cleaner head of the dust collector is connected with a long pipe through an assembly joint 1 and further connected with a main machine of the dust collector, or is directly connected with the main machine of the dust collector through the assembly joint 1. After being connected with the main machine of the dust collector, when the dust collector is started, a negative pressure area is generated at the main machine of the dust collector and is expanded to the inside of the air duct of the cleaning head through the connecting pipeline 63. Under the action of the pressure difference between the inside and the outside, the outside air flow and the dust and dirt particles carried by the outside air flow are sucked into a dust collecting cavity of the main machine of the dust collector.
Referring to fig. 2 and 3, in particular, the cleaner head of the vacuum cleaner comprises a housing 2, wherein a negative pressure cavity 3 is formed in the housing 2, and the negative pressure cavity 3 is used for being connected with a main machine of the vacuum cleaner to generate negative pressure. The negative pressure cavity 3 is connected with a main dust suction port 4 and a side dust suction port 5 which are mutually independent, the main dust suction port 4 is positioned between end plates 21 at two sides of the shell 2, and the side dust suction port 5 is positioned on the end plates 21 of the shell 2.
Specifically, the housing 2 has a main plate 22 formed between the end plates 21 on both sides, and the main dust suction port 4 is opened in the main plate 22. A rotatable roller brush 8 is erected between the two end plates 21, and a main dust suction port 4 is arranged at the position of the main plate 22 opposite to the roller brush 8 to assist the roller brush 8 in dust suction. And the negative pressure chamber 3 is connected with the main dust suction port 4 through a main dust suction pipe 7 arranged along the axial direction.
And a side dust suction pipe 6 is protruded on the outer wall of the end plate 21, and a side dust suction port 5 is provided at the end of the side dust suction pipe 6. The side suction pipe 6 includes a first pipe body 61 extending in the width direction of the casing 2, a second pipe body 62 extending in the height direction of the casing 2 is formed at the end of the first pipe body 61, and the side suction port 5 is provided at the end of the second pipe body 62 so as to provide the side suction port 5 at a lower corner of the end plate 21 on the side away from the negative pressure chamber 3. In order to ensure the air suction effect, the diameter of the second tube 62 is gradually increased with distance from the first tube 61. The first pipe body 61 is connected to the main suction pipe 7 through a radially disposed connecting duct 63.
When one end of the cleaning head provided with the side dust suction port 5 is attached to a corner to suck dust, the suction airflow of the side dust suction port 5 can act on dust particles at the corner between a wall and a floor to the maximum extent, the spacing distance between the negative pressure area of the side dust suction port 5 and the wall is only limited by the wall thickness of the side dust suction pipe body material (generally not more than 2 mm), and the side dust suction port can greatly narrow compared with the spacing distance (more than 10 mm) between the negative pressure area and the wall of the existing dust collector cleaning head, and can achieve a better cleaning effect on the corner.
A valve body is provided in the connection pipe 63 to control the opening and closing of the side dust suction port 5. The user can select to open or close the valve according to the use scene (such as whether the corner part needs to be cleaned). When the valve is opened, the connecting pipeline 63 is unblocked, and the side dust suction port 5 generates suction airflow; when the valve is closed, the connecting duct 63 is cut off and the connection of the side suction opening 5 to the suction chamber 3 is cut off, so that the suction air flow is lost, and the total air intake cross-sectional area of the cleaner head is reduced, so that a greater suction air flow can be obtained at the main suction opening 4, and a better cleaning effect can be obtained in this area.
It is to be understood that the present invention has been described with reference to certain embodiments and that various changes in form and details may be made therein by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof.
