The specific implementation mode is as follows:

the following will further explain the embodiments of the present invention with reference to the drawings and examples:

in the description of the present invention, it should be understood that the description indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and does not indicate or imply that the device or element indicated must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the scope of the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1

The utility model provides a still pressure boost air washer, includes casing 5, open 5 front ends of casing has the air intake, 5 internal fixation of casing has the motor, the output shaft drive of motor has the impeller, still includes the still subassembly, the still subassembly includes still wheel cap 1, still 1 welded fastening of still wheel cap is in the air intake of 5 front ends of casing, 1 rear portion welded fastening of still wheel cap has round drainage piece group, the impeller includes the fan blade group, drainage piece group be located the air intake port department of fan blade group and leave the clearance between the fan blade group to do not produce with drainage piece group when ensureing that fan blade 4 in the fan blade group is rotatory and interfere. The arrangement angle of the drainage sheets 2 in the drainage sheet group is consistent with that of the fan blades 4 in the fan blade group. The impeller further comprises an upper wheel cover 3 and a lower wheel cover 8, the fan blade group is fixedly welded between the upper wheel cover 3 and the lower wheel cover 8, and the middle part of the lower wheel cover 8 is fixedly connected to an output shaft of the motor (the lower wheel cover 8 and the output shaft of the motor can be directly fixedly welded or can be fixedly connected by additionally arranging a connecting shaft). The stator wheel cover 1 and the upper wheel cover 3 are respectively of a hollow structure. And an air inlet channel is arranged in the middle of the stator vane wheel cover 1. The motor is characterized by further comprising a motor barrel 6, the motor barrel 6 covers the outside of the motor 7, the motor 7 is fixed in the motor barrel 6 through bolts, the motor barrel 6 is fixed in the machine shell 5 through a connecting frame in a welding mode, and the motor barrel 6 plays a role in protecting the motor 7.

During normal work operation, at the space before impeller flabellum air inlet port, because the air pull the effect and form a rotator, the compressibility of gas has influenced the ability of organizing of air current, the utility model provides a set of static drainage piece 2 has been installed at this space region to this kind of still pressure boost air washer, makes this regional air current become can organize the air current, and then has increased the wind pressure that air washer produced, and then makes this kind of still pressure boost air washer possess better performance. The stator supercharging air washer effectively utilizes the limited space in the casing 5, and compared with the mode of increasing the wind pressure by increasing the size of the fan blades, the inner diameter of the casing 5 is not required to be enlarged.

In short, the above description is only a preferred embodiment of the present invention, and all the equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the scope of the present invention.
