A filter box 5 is fixed to the top surface of the base 1 at the rear side of the air shower chamber 2, and the air inlet end is connected to the air outlet end of the base 1. An air purification filter is installed in the filter box 5.

[0026] The circulating air pump 4 is fixed on the top of the air shower chamber 2. The air inlet and air outlet of the circulating air pump 4 are respectively connected to an air extraction pipe 4.1 and an air exhaust pipe 4.2. The air inlet of the air extraction pipe 4.1 is connected to the air outlet of the filter box 5. The air outlet of the air exhaust pipe 4.2 passes through the center of the top surface of the air shower chamber 2.

[0027] The rotary air shower mechanism 7 is composed of an air distribution mechanism and a rotary air outlet mechanism. Specifically, the outer edge of the fixed plate 7.1 is fixed to the top surface of the inner cavity of the air shower chamber 2 by bolts, the top of the air distribution cylinder 7.2 is fixedly sleeved on the center of the fixed plate 7.1, and the air outlet end of the exhaust pipe 4.2 is sleeved on the top of the air distribution cylinder 7.2, and a plurality of air outlet holes 7.2.1 are circumferentially arranged in the middle of the outer peripheral wall of the air distribution cylinder 7.2. The annular shell 7.3 is rotatably sleeved on the air distribution cylinder 7.2, and a plurality of air inlet holes 7.3.1 are circumferentially arranged in the middle of the inner peripheral wall of the annular shell 7.3, and a connecting port 7.3.2 is arranged in the middle of the outer peripheral wall of the annular shell 7.3. The outer edge of the top opening of the inverted L-shaped tube body 7.5 is provided with an arc-shaped connecting plate 7.5.2, and the arc-shaped connecting plate 7.5.2 is fixed to the outer peripheral wall of the annular shell 7.3 at a position corresponding to the connecting port 7.3.2. The inner side wall of the inverted L-shaped tube body 7.5 is provided with a plurality of nozzles 7.5.1.

[0028] The bottom surface of the fixing plate 7.1 is fixed with an annular guide rail 7.1.1 at a position outside the air distribution cylinder 7.2. The fixing plate 7.1 is provided with an axial hole 7.1.2 near the outer edge. The top surface of the air shower chamber 2 is fixed with a driving motor 6 at a position corresponding to the axial hole 7.1.2. The axial hole 7.1.2 is rotatably sleeved with a vertical shaft 7.8 whose top end is connected to the power output shaft of the driving motor 6.

The inner peripheral wall of the outer gear ring 7.7 is fixed with a slider 7.6 that is slidably engaged with the annular guide rail 7.1.1.

[0030] In summary, when air showering a person or object, the person or object is first placed on the hollow plate 1.1, and the closed doors 3 on both sides are closed. The circulating air pump 4 and the drive motor 6 are turned on. The drive motor 6 drives the inverted L-shaped tube body 7.5 and the annular shell 7.3 to rotate as a whole through the vertical shaft 7.8, the driving gear 7.9 and the outer gear ring 7.7. At the same time, the slider 7.6 rotates along the annular guide rail 7.1.1, providing support for the inverted L-shaped tube body 7.5, so that the inverted L-shaped tube body 7.5 and the annular shell 7.3 can rotate smoothly as a whole. The inverted L-shaped tube body 7.5 rotates around the person or object. The gas at the outlet of the circulating air pump 4 enters the inner cavity of the inverted L-shaped tube 7.5 through the exhaust pipe 4.2, the inner cavity of the air distribution cylinder 7.2, the air outlet hole 7.2.1, the air inlet hole 7.3.1, the inner cavity of the annular shell 7.3, and the connecting port 7.3.2, and finally sprays out from the spray hole of the nozzle 7.5.1 to blow off the dust on the surface of people or objects. The inner cavity of the base 1 is in a negative pressure state, so the dust that is discharged enters the inner cavity of the base 1 through the through hole on the hollow plate 1.1 with the air. This part of the air is filtered by the filter box 5 and then enters the air inlet end of the circulating air pump 4 through the exhaust pipe 4.1 to form a circulating wind flow.

[0031] A rotating ring 7.4 is respectively mounted between the top and bottom ends of the inner cavity of the annular housing 7.3 and the gas distribution cylinder 7.2. The rotating ring 7.4 includes a bearing and a rotating sealing structure to ensure that the annular housing 7.3 rotates smoothly relative to the gas distribution cylinder 7.2 and prevents air leakage at the top and bottom ends of the connection between the two.
