The spacing between the two adjacent rows of second through holes 3 is equal to the spacing between the two adjacent rows of first through holes 2, and the spacing between the two adjacent second through holes 3 in each row is equal to the spacing between the two adjacent first through holes 2 in each row.
[0027] An opening is formed above the side surface of the barrel, the opening is above all the first through holes 2, and a first buckle 15 and a second buckle 16 are arranged on the side wall of the barrel and close to the upper and lower ends of the opening, respectively. The end of the first buckle 15 and the second buckle 16 is a wedge-shaped structure. A toggle switch 4 is arranged at the opening of the clamping plate layer, the toggle switch includes a pressing block 12, a toggle block 11, a first hook 13 and a second hook 14, the pressing block 12 is arranged on the clamping plate layer, the toggle block 11 is arranged on the pressing block 12, and the first hook 13 and the second hook 14 are arranged at the upper and lower ends of the pressing block 12, respectively. The end of the first hook 13 and the end of the second hook 14 are wedge-shaped structures, the first hook 13 is matched with the first buckle 15, and the second hook 14 is matched with the second buckle 16, that is, the slope surface of the wedge-shaped structure of the first hook 13 is matched with the slope surface of the wedge-shaped structure of the first buckle 15, and the slope surface of the wedge-shaped structure of the second hook 14 is matched with the slope surface of the wedge-shaped structure of the second buckle 16.
[0028] The toggle block 11 is exposed outside the opening, and the toggle block 11 can drive the clamping plate layer to move up and down, the pressing of the toggle block 11 can drive the clamping plate layer and the pressing block 12 to move in a direction perpendicular to the axis of the barrel, that is, the pressing of the toggle block 11 can further press the clamping plate layer and the pressing block 12, and when pressed, the first hook 13 and the second hook 14 on the pressing block 12 can move away from the first buckle 15 and the second buckle 16.
[0029] When the toggle switch 4 moves to one end of the cylinder, the first through hole 2 and the second through hole 3 are aligned and communicated, and when the toggle switch 4 moves to the other end of the cylinder, the first through hole 2 and the second through hole 3 are misaligned, and the first through hole 2 is closed by the clamping plate layer. In the embodiment, when the toggle switch 4 moves upward, the first hook 13 is clamped with the first buckle 15, and each second through hole 3 on the clamping plate layer is misaligned with each first through hole 2, and each first through hole 2 is closed by the clamping plate layer; when the toggle switch 4 moves downward, the second hook 14 is clamped with the second buckle 16, and each row of second through holes 3 on the clamping plate layer is aligned and overlapped with each row of first through holes 2 on the cylinder, so that each corresponding first through hole 2 and each second through hole 3 are communicated.

[0032] When the clamping plate layer closes the first through hole 2, the device is in a normal dust cleaning mode, and a single channel ensures maximum dust cleaning power, which is suitable for cleaning the dust on the surface. The shape and size of the first through hole 2 are compatible with most nozzle products on the market, and can be replaced and used according to the needs. Compared with the traditional cylindrical nozzle, the flat end of the fan-shaped main nozzle 4 greatly increases the air pressure of the nozzle and improves the dust cleaning efficiency, and can clean the dust stubbornly adhered to the reinforcement. The first through hole 2 is arranged around the outer sidewall of the cylinder, and can be responsible for cleaning the part of 120 degrees of the side, so as to achieve 360-degree side angle without dead angle cleaning.
[0033] The working process of the utility model is as follows:
[0034] When the deep dust cleaning mode is needed, the toggle switch 4 is slid downward in the opening, the slope surface of the wedge-shaped structure on the second hook 14 is matched with the slope surface of the wedge-shaped structure on the second buckle 16, the second hook 14 is slid into the groove on the second buckle 16 to clamp the second hook 14 with the second buckle 16, at this time, each row of second through holes 3 on the clamping plate layer is aligned and overlapped with each row of first through holes 2 on the cylinder, so that each corresponding first through hole 2 and each second through hole 3 are communicated, and the nozzle of the appropriate type is inserted into the communicated first through hole 2 and second through hole 3, the top end of the cylinder is communicated with the blowing device, and the nozzle works together with the fan-shaped main nozzle 1.
[0035] Due to gravity, the initial position of the toggle switch 4 is that the second hook 14 is clamped with the second buckle 16, when the ordinary dust cleaning mode is needed, the toggle block 11 is pressed to drive the second hook 14 to be separated from the second buckle 16, and then the toggle block 11 is upwardly toggled to drive the clamping plate layer to move upwardly, when the first hook 13 contacts with the first buckle 15, due to the matching of the slope surfaces of the wedge-shaped structures of the first hook 13 and the first buckle 15, the first hook 13 is slid into the groove of the first buckle 15 to clamp the first hook 13 with the first buckle 15, at this time, each second through hole 3 on the clamping plate layer is staggered with each first through hole 2, and the clamping plate layer closes each first through hole 2 to connect the top end of the cylinder with the blowing device, and only the fan-shaped main nozzle 1 is used for blowing work.
[0036] When the ordinary dust cleaning mode is switched to the deep dust cleaning mode, the toggle block 11 is pressed again to drive the first hook 13 to be separated from the first buckle 15, and then the toggle block 11 is downwardly slid to drive the second hook 14 to be clamped with the second buckle 16.
[0037] The scheme sets two dust cleaning modes, the ordinary dust cleaning mode, only the high-pressure fan-shaped main nozzle works, a single channel guarantees the maximum dust cleaning power, and the ordinary dust cleaning mode is suitable for cleaning the dust on the surface, the deep dust cleaning mode, a plurality of nozzles are installed on the device, and the deep dust cleaning mode is suitable for being used when the spray head is stretched into the inside of the reinforcement mesh, and the dust on the bottom and the surrounding reinforcement is cleaned at the same time, the dust cleaning efficiency is greatly improved, compared with the traditional spray head, the dust in the reinforcement mesh and the dust in the dead angle can be cleaned more efficiently, and the dust cleaning operation is facilitated, with the improvement of the dust cleaning efficiency, the health of the operator is positively affected, and the operator is prevented from being in the high-density dust environment for a long time.
