[0002] In the fields of precision machinery manufacturing, electronic processing, etc., the cleanliness of dust-free workshops directly affects the product yield and service life. In traditional dust-free workshops, air showers are generally used to remove particulate matter on the surface of personnel's clothes. However, since the soles of shoes are in direct contact with the ground, they are easily attached with a large amount of dust and pollutants, and the amount of particles carried is far more than that of clothes. There are obvious technical blind spots in the existing air shower system for cleaning the soles of shoes.

[0003] Most of the current sole cleaning devices use fixed brushes or simple air flow dust removal, and there are the following technical defects:

[0004] 1. It is difficult for a fixed brush to cover the concave and convex textures of the sole, and particles are easily left behind;

[0005] 2. The removed dust is not effectively collected and is easily diffused into the workshop with the air flow;

[0006] In view of the above problems, it is urgent to develop a special cleaning device for soles that integrates dynamic cleaning and efficient dust removal to fill the technical gap in the purification link at the entrance of the dust-free workshop and ensure the full-process control of the clean environment.

[0027] In this embodiment: the worker places the sole of the shoe on the support roller 4 of the cleaning mechanism. Since the highest point of the brush sleeve 6 is higher than the support roller 4, the sole of the shoe will contact the brush sleeve 6. The motor 18 drives the worm gear 19 to rotate, and the worm gear 19 drives the worm wheel 17 to rotate the rotating roller 5. The rotating brush sleeve 6 performs dynamic cleaning on the sole of the shoe, which can better cover the uneven texture of the sole. At the same time, the fan 8 starts. Under the action of the dust removal mechanism, a negative pressure is formed at the box 2 and the dust suction hood 3 through the flexible air duct, which sucks in the dust generated during the cleaning process. The dust enters the filter box 7 through the air inlet pipe 10, and the purified air is discharged from the air outlet pipe 9. This can effectively collect the dust generated during the cleaning process, prevent the dust from spreading to the workshop with the airflow, and ensure the cleanliness of the workshop.

[0028] As a technical optimization of this utility model, the filter box 7 is provided with an activated carbon filter plate 11 and a HEPA filter plate 12 from bottom to top. The two are detachably mounted on the side wall of the filter box 7 via a sliding rail. The activated carbon filter plate 11 is located above the air inlet pipe 10, and the HEPA filter plate 12 is located below the air outlet pipe 9.

[0029] In this embodiment: the activated carbon filter plate 11 performs primary filtration of particles ≥5μm, and the HEPA filter plate 12 performs secondary filtration of particles ≥1μm, achieving multi-stage purification while facilitating maintenance.

[0030] As a technical optimization of this utility model, the bottom of the filter box 7 forms a collection hopper 13 with a cone angle of 60-75°, and a dust discharge valve pipe 14 is provided at the center of the bottom of the collection hopper 13.

[0031] In this embodiment: the 60-75° collecting hopper 13 can guide particles to gather towards the dust discharge valve pipe 14. Opening the dust discharge valve pipe 14 below the collecting hopper 13 makes it easy to clean the dust collected and filtered inside the collecting hopper 13.

[0032] As a technical optimization of this utility model, the filter box 7 is provided with an observation window 15, which is a viewing window made of double-layer acrylic sheet, and the inner side plate surface is provided with an anti-static coating.

[0033] In this embodiment: the viewing window facilitates observation of the interior of the filter box 7, while preventing static electricity from attracting dust and making it easy to clean the collection hopper 13 in a timely manner.

[0034] As a technical optimization of this utility model, a transmission cavity 16 is opened in the interlayer of the box 2, one end of all the rotating rollers 5 extends into the transmission cavity 16 and is respectively provided with worm gears 17, a motor 18 is provided on the inner wall of the transmission cavity 16, and the output shaft of the motor 18 is fixedly connected to a worm 19 that is connected to the worm gears 17 for transmission.

[0035] In this embodiment: the starting motor 18, worm gear 19 and worm wheel 17 are rotated, so that the rotating roller 5 provides power for the cleaning mechanism, so that the sole of the shoe comes into contact with the brush sleeve 6, making it easy to clean the sole of the shoe, and the sole of the shoe moves on the support roller 4, so that the sole of the shoe can be cleaned thoroughly; the worm gear 19 is made of nylon-coated copper material, which has low operating noise.

[0036] As a technical optimization of this utility model, the housing 2 has heat dissipation holes 20 that communicate with the transmission cavity 16.

[0037] In this embodiment: the heat dissipation hole 20 is opened on the housing 2 and communicates with the transmission cavity 16 to dissipate the heat generated by the generator 18.

[0038] As a technical optimization of this utility model, the dust cover 3 is provided with a number of support rods 21 arranged in front and behind and fixed to the bracket 1. The support rods 21 are telescopic rods with adjustable length.

[0039] In this embodiment: the support rod 21 can be used as a handrail, which is easy for workers to grip and makes it easy to lift their feet to clean the dust steadily. Alternatively, a stool can be set on one side of the box 2.

[0040] Working principle and usage process of this utility model:

[0041] The cleaning device used in this cleanroom is mainly used to clean the dust on the soles of workers' shoes. During operation, workers place the soles of their shoes on the support roller 4 of the cleaning mechanism. Since the highest point of the brush sleeve 6 is higher than the support roller 4, the soles of the shoes will contact the brush sleeve 6. The motor 18 drives the worm gear 19 to rotate, and the worm gear 19 drives the worm wheel 17 to rotate the rotating roller 5. The rotating brush sleeve 6 performs dynamic cleaning on the soles of the shoes, which can better cover the uneven texture of the soles. At the same time, the fan 8 starts, and under the action of the dust removal mechanism, a negative pressure is formed at the box 2 and the dust suction hood 3 through the flexible air duct, which sucks in the dust generated during the cleaning process. The dust enters the filter box 7 through the air inlet pipe 10. The dust first passes through the activated carbon filter plate 11 to adsorb some odors and large dust particles, and then passes through the HEPA filter plate to further filter out small particles. The purified air is discharged from the air outlet pipe 9. The dust falls into the collection hopper 13 at the bottom of the filter box 7 under the action of gravity, and can be discharged periodically through the dust discharge valve pipe 14.
