The specific technical solution and the advantages of the present invention will be described in detail in the following detailed description with reference to the accompanying drawings.

Drawings

The invention will be further described with reference to the accompanying drawings and specific embodiments:

FIG. 1 is a schematic view of the general structure of the cutting type surface aerator of the present invention;

fig. 2 is a schematic view of the exploded structure of the cutting type surface aerator of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It will be appreciated by those skilled in the art that features from the examples and embodiments described below may be combined with each other without conflict.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Such as the following terms "upper", "lower", etc., indicating an orientation or positional relationship, are based only on the orientation or positional relationship shown in the drawings and are merely for convenience in describing the present invention and simplifying the description, rather than indicating or implying that the device/element referred to must have a particular orientation or be constructed and operated in a particular orientation and therefore should not be construed as limiting the invention.

As shown in fig. 1 and 2, the cutting type surface aerator comprises a float 1 with a water absorbing channel 11, a water flow guide plate 2 and a motor 3, wherein the water flow guide plate 2 and the motor 3 are arranged above the float and just face the water absorbing channel, the water flow guide plate 2 is in an inverted cone shape and covers the water absorbing channel to enable water sprayed by the water absorbing channel to disperse around, and contacts with air to form water drops in the flying process, the water drops collide with the liquid surface when falling down to enable oxygen in water to be increased, the motor 3 is vertically arranged, the lower end of a motor output shaft 31 downwards penetrates out of the water flow guide plate and extends into the water absorbing channel 11, a rainproof cover is arranged on the upper side of the motor 3, an impeller 32 is installed at the lower end of the motor output shaft, and a water inlet guide pipe.
