The cleaning equipment in the embodiment comprises the cavity-divided air knife, so that the cleaning equipment cannot cause waste of air quantity, the energy-saving effect is good, and the practicability of the cleaning equipment is good.

In this embodiment, five air inlet cavities are arranged inside the casing 1, and the structures of the air inlet cavities may be the same or different, and are not limited herein; and each air inlet cavity is internally provided with an air inlet pipe 2, one end of each air inlet pipe 2 is positioned in the air inlet cavity, and the other end of each air inlet pipe 2 is connected with an air source so as to provide air for the air inlet cavity. In other embodiments, two or another number of air inlet pipes 2 may be disposed in the air inlet cavity, and are not limited in particular.

Further, as shown in fig. 1 to 3, the casing 1 includes a wind knife housing 11 and a cover plate 12; a plurality of open cavities 111 arranged at intervals in a first direction are formed inside the air knife shell 11, the air knife shell 11 is provided with a mounting part and a gap part which are positioned on the same side, and the end surface of the gap part is lower than the end surface of the mounting part in a second direction; when the cover plate 12 is covered and abutted to the mounting portion in the second direction, the above-described air inlet cavity can be formed between the opening cavity 111, the mounting portion, and the cover plate 12, and the above-described airflow outlet 13 can be formed between the cover plate 12 and the gap portion. The housing 1 in this embodiment is made of aluminum. The second direction is parallel to the width direction of the housing 1, and the second direction is specifically shown by an arrow Y in fig. 3.

Specifically, as shown in fig. 3, the gap portion includes a gap side 114, and a length of the gap side 114 extends in the first direction; the mounting portion comprises a mounting side surface 112 and spacing support members 113, one spacing support member 113 is arranged between every two adjacent opening cavities 111, the length of each spacing support member 113 extends along the vertical direction, one end of each spacing support member 113 is connected to the mounting side surface 112, and the other end of each spacing support member 113 is located on a gap side surface 114; in the second direction, the end face of the spacing support 113 is flush with the mounting side face 112, so that when the cover plate 12 is covered to the air knife housing 11 along the second direction, the cover plate 12 can be simultaneously abutted to the end face of the spacing support 113 and the mounting side face 112, so that the end faces of the cover plate 12, the mounting side face 112 and the spacing support 113 are abutted tightly, the gas in the opening cavity 111 cannot overflow through the gap between the cover plate 12 and the mounting side face 112, and the end face of the cover plate 12 and the spacing support 113, and therefore it can be ensured that the cover plate 12, the mounting side face 112, the spacing support 113 and the opening cavity 111 form an air inlet cavity, and further it can be ensured that the gas in the air inlet cavity can only be blown to the air outlet area of the air outlet 13 corresponding to the air inlet cavity from top to bottom. Wherein the vertical direction is specifically indicated by arrow Z in fig. 3.

By arranging the spacing support part 113, on one hand, the spacing support part 113 is used for being abutted to the cover plate 12, so that the spacing support part 113 and the cover plate 12 can generate a supporting effect mutually, and the problem that the cover plate 12 and the air knife shell 11 deform at the middle position of the air outlet 13 is solved, so that the air outlet 13 can form a uniform air outlet surface, and the uniformity of air outlet of the air outlet 13 and the stability of air pressure are ensured; on the other hand, the two adjacent opening cavities 111 can be blocked, so that air inlet cavities arranged at intervals can be formed.

Further, the flatness of the cover plate 12 matches the flatness of the end faces of the mounting side face 112 and the spacing support 113, so that the abutting between the cover plate 12 and the mounting side face 112 and between the cover plate 12 and the end face of the spacing support 113 can be tighter, and further a plurality of air inlet cavities arranged at intervals can be guaranteed to be formed.

Specifically, as shown in fig. 3, in the vertical direction, the end portion of the spacing support member 113 located on the gap side surface 114 is higher than the bottom end of the gap side surface 114, that is, in the vertical direction, the spacing support member 113 does not penetrate through the whole gap side surface 114, so that the gas in two adjacent air inlet cavities can flow from the bottom end of the spacing support member 113, and it is ensured that the gas in two adjacent air inlet cavities can be uniformly mixed and then blown out from the airflow outlet 13, so that it can be ensured that the air to be blown out of the workpiece 3 is relatively uniform. Wherein the end of the spacing support 113 on the gap side 114 is 1mm-3mm higher than the bottom end of the gap side 114.

It should be noted that, because the distance from the end of the spacing support 113 on the gap side 114 to the bottom end of the gap side 114 is smaller in the vertical direction, when there is gas in only one air inlet cavity, a very small amount of gas can flow into the adjacent air inlet cavity through the bottom end of the spacing support 113, but the gas in the air inlet cavity is not influenced to be blown out only from the air outlet area of the airflow outlet 13 corresponding to the air inlet cavity; when gas exists in the two adjacent air inlet cavities, the gas has fluidity, so that the gas in the two adjacent air inlet cavities can flow from the bottom end of the spacing support piece 113, and the gas in the two adjacent air inlet cavities can be uniformly mixed and then blown out from the gas flow outlet 13.

Further, as shown in fig. 3, a first step surface 115 and a second step surface 116 are disposed between the opening cavity 111 and the gap side surface 114, the lengths of the first step surface 115 and the second step surface 116 extend along a first direction, and in a second direction, the first step surface 115, the second step surface 116 and the gap side surface 114 are gradually increased so that the first step surface 115 and the second step surface 116 can provide a flowable space for the gas in the opening cavity 111, so that the gas in the opening cavity 111 can be blown to the gap side surface 114 through the first step surface 115 and the second step surface 116 in sequence, and further blown out from the gas outlet 13 formed between the gap side surface 114 and the cover plate 12.

Specifically, as shown in fig. 3, at the bottom end close to the gap side surface 114 in the vertical direction, the width and the thickness of the spacing support member 113 are gradually reduced, so that the spacing support member 113 can form an inverted cone structure, so that the gas in the intake cavities can be collected to the position on the gap side surface 114 on the spacing support member 113, and the gas between two adjacent intake cavities can be uniformly mixed through the bottom end of the spacing support member 113 and then blown out from the airflow outlet 13. The spacing support member 113 in this embodiment may be a strip-shaped plate with an inverted conical structure, and because the length of the strip-shaped plate is long and the strip-shaped plate is of an integral structure, the processing is simple and convenient compared with the spacing support member 113 with a dot or boss structure.

Further, as shown in fig. 1 and 3, a plurality of first screw holes 117 are provided on both the mounting side surface 112 and the interval supporter 113, a second screw hole 121 matching the first screw hole 117 is provided on the cover plate 12, and a fastener is threadedly inserted into the first screw hole 117 and the second screw hole 121, thereby threadedly coupling the cover plate 12 to the air knife housing 11. In this embodiment, the fastener may be a screw. In other embodiments, the cover plate 12 and the air knife housing 11 may be connected by a snap or other connection method.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
