Technical Field

The application relates to the technical field of cleaning equipment, in particular to a vacuum cleaner.

Background

Vacuum cleaners have a number of components, typically including a nozzle portion, a dirt cup portion, a motor portion and corresponding ducting and operating components. Vacuum cleaners rely on a drive motor to generate a vacuum before a dirty air inlet reaches the motor impeller. The vacuum created collects debris from the surface to be cleaned, passes it through the dirty air intake duct, and accumulates the debris in the dirt cup portion, thereby effecting cleaning. Vacuum cleaners currently on the market have a dirty air inlet in the form of a single suction duct. Therefore, when the surface of the window curtain and other tension-free objects are cleaned, the surface tension-free objects such as the window curtain and the like are attached to the dirty air inlet due to the negative pressure in front of the suction inlet, and the vacuum cleaner is prevented from continuously moving. In addition, when the pet hair and the epidermis are subjected to dust absorption and mite removal by using the vacuum cleaner, the pet hair is sucked into the dirty air inlet, so that the root of the pet hair is greatly pulled, and the pet comfort is low.

As shown in fig. 7 and 8, the flow direction of the clean air discharged from the air outlet 103, i.e., the second direction F2, may be diffused toward the periphery of the negative pressure region at the front side of the dirty air inlet 109, or may be gathered toward the negative pressure region at the front side of the dirty air inlet 109, and is not necessarily at an angle of 180 ° with respect to the first direction F1. The specific angle between the first direction F1 and the second direction F2 is defined by the structure of the air blowing nozzle 105, and the specific structure of the air blowing nozzle 105 and the specific angle between the first direction F1 and the second direction F2 are not limited to the protection scope of the present application.

Referring to fig. 9 and 10, the present application provides a schematic view of a blowing nozzle 1052 configuring another structure of the vacuum cleaner and a perspective view of the blowing nozzle 1052. The air blowing nozzle 1052 is characterized in that the area of an exhaust outlet is enlarged, clean air is exhausted through an exhaust port 1054 arranged at the front end part of the air blowing nozzle 1052, and meanwhile, a synapse 1053 provided with an exhaust mesh is additionally arranged at the front end part of the air blowing nozzle 1052, so that when a vacuum cleaner is used for sucking dust and removing mites on pet skins and hair, a certain distance can be always kept between the vacuum cleaner and the root of pet hair, the pulling of the negative pressure of a dirty air suction channel to the root of the pet hair can be effectively relieved, the pet hair can be combed and the pet can be massaged, and the efficiency of using vacuum dust suction to nurse the pet hair and the comfort level of the pet hair are improved.

In the above two embodiments, the air blowing nozzle 105 and the air blowing nozzle 1052 may be set to other suitable sizes according to practical needs, and only need to be able to connect with the vacuum cleaner, which does not limit the scope of protection of the present application.
