[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0029] Example 1

[0030] like Figures 1 to 8 As shown, a blower cover 1 is provided with one or more mounting interfaces 32 for mounting an air nozzle, so that the air nozzle can extend into the blower and face the impeller in the blower.

[0031] By providing one or more mounting interfaces 32 for installing the air nozzle on the blower cover 1, the air nozzle can be extended into the blower and directed toward the impeller inside the blower. The impeller inside the blower can be cleaned without removing the blower cover 1, thereby simplifying the work process and improving the efficiency of cleaning the impeller.

[0032] like Figures 1 to 7 As shown, a cover hole 3 is opened on the cover plate 1, and a blocking cover 31 is arranged in the cover hole 3. The mounting interface 32 is arranged on the blocking cover 31. The blocking cover 31 and the cover plate 1 are detachably connected to facilitate the installation and replacement of the air nozzle on the cover plate 1.

[0033] Reference Figure 5 and Figure 6 The cover plate 1 is provided with a functional portion 33, which is a boss protruding from the outer surface of the cover plate 1. The cover plate hole 3 is formed on the functional portion 33, and a mounting end surface 331 is provided on the outer end surface of the functional portion 33. The provision of the functional portion 33 enables the plugging cover 31 to better cooperate with the cover plate 1, thereby improving the sealing performance between the two.

[0034] like Figure 8As shown, the plug cover 31 includes a mounting portion 311, and a flange connection portion 312 for mounting the plug cover 31 is provided around the mounting portion 311. The mounting portion 311 is arranged in the cover plate hole 3. The flange connection portion 312 cooperates with the mounting end surface 331 on the outside of the cover plate 1 located around the cover plate hole 3, so that the inner side surface of the plug cover 31 matches the inner side surface of the cover plate 1. The mounting end surface 331 limits the flange connection portion 312 of the plug cover 31, and the plug cover 31 is installed in the cover plate hole 3, so that the inner side surface of the plug cover 31 is consistent with the inner side surface of the cover plate 1 formed by the inner side surface of the cover plate 1, which will not affect the normal operation of the impeller and will not affect the airflow inside the blower. The provision of the flange connection portion on the plug cover can simultaneously perform the functions of installation, positioning, and sealing, thereby ensuring the performance of the cover plate.

[0035] In some embodiments, the inner side surface of the cover plate 1 is a conical surface that expands toward the inside of the blower, thereby increasing the flow performance of the high-pressure air ejected from the air nozzle inside the blower and making the interior of the blower clean more thoroughly.

[0036] In some embodiments, the flange connection portion 312 is provided with a connection hole for installing bolts. The plugging cover 31 is fixed in the cover plate hole 3 by the cooperation of the bolts and the connection hole, and the connection is made by bolts, making the installation and removal of the plugging cover 31 simpler and more convenient.

[0037] Example 2

[0038] like Figure 1 、 Figure 2 and Figure 7 As shown, the cover plate 1 includes two semicircular cover bodies 11, and a cover plate hole 3 is provided on one of the cover bodies 11, or a cover plate hole 3 is provided on both cover bodies 11, and the two cover plate holes 3 are centrally symmetrical along the center point of the cover plate 1. In this way, two groups of air nozzles can be set at different positions on the cover plate at the same time, and the impeller inside the blower can be cleaned at the same time, which can speed up the flow speed of the airflow inside the blower, make the inside of the blower cleaner, and improve the cleaning efficiency.

[0039] The cover plate hole 3 can be a square hole or a circular hole, preferably a square hole.

[0040] The cover body 11 includes an end cover 111 and a connecting portion 2 for connecting to the air duct. L-shaped connecting flanges 12 are respectively provided at both ends of the cover body 11 along the diameter direction. The connecting flanges 12 are respectively connected to the end cover 111 and the connecting portion 2. The cover bodies 11 are connected through the connecting flanges 12, which increases the convenience of installing the blower cover plate 1 and improves the reliability of installing the blower cover plate 1.

[0041] Example 3

[0042] A blower cover plate has a cover plate hole 3 formed on the cover plate 1, a blocking cover 31 is arranged in the cover plate hole 3, and one or more air nozzles (not shown in the figure) are arranged on the blocking cover 31. When the cover plate 1 is installed on the blower, the air nozzles can extend into the blower and face the impeller inside the blower.

[0043] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. used to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0044] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this invention does not necessarily mean that the components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that the direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0045] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention falls within the scope of protection of the present invention.
