[0002] At present, the processing and manufacturing industries such as electronics and precision instruments have high requirements for the cleanliness of the air in the production sites, so the cleanliness of the production sites needs to be strictly controlled. The air shower room is one of the necessary purification equipment for workers to enter the clean room or dust-free workshop. The super-strong clean airflow circulating inside the air shower room can effectively and quickly remove dust, hair, hair dandruff and other debris attached to clothes. It can minimize the pollution problems caused by employees entering and leaving the clean room.

[0003] However, the existing air shower room can only clean the dust or hair adsorbed on the clothes. Before entering the air shower room, even if the staff change their work shoes, they still need to walk a certain distance to enter the air shower room. Therefore, the soles of the staff's shoes often carry a lot of dust, and the dust on the soles of the shoes is stepped on, so the dust can be firmly adsorbed on the soles of the shoes. During the air shower process, the staff stands in the air shower channel, and the high-speed airflow is difficult to effectively clean the soles of the staff's shoes, resulting in the soles of the staff still carrying a lot of dust into the dust-free workshop.

[0034] The following is combined with Figures 1 to 3 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] refer to Figure 1The embodiment of the present application discloses a dust removal air shower room, which includes a room body 10, a sole cleaning mechanism 50, a first fan 20 and a second fan 21. The top and sides of the room body 10 can be ventilated; the sole cleaning mechanism 50 is arranged in the room body 10, and the internal space of the room body 10 is divided into a main air chamber 11 and a return air chamber 12. The main air chamber 11 is located above the return air chamber 12, and the main air chamber 11 is connected to the return air chamber 12 through the sole cleaning mechanism 50; the first fan 20 is used to blow air toward the top of the main air chamber 11; the second fan 21 is used to form an airflow from the return air chamber 12 to the side of the main air chamber 11; the filter component is used to intercept dust in the airflow.

[0036] In this way, this embodiment sets a sole cleaning mechanism 50 in the chamber body 10, so that after the staff enters the main air chamber 11, the sole cleaning mechanism 50 can be operated to remove the dust on the soles. At the same time, since the main air chamber 11 and the return air chamber 12 are connected through the sole cleaning mechanism 50, the first fan 20 and the second fan 21 can realize the high-speed air flow circulation from the main air chamber 11 through the sole cleaning mechanism 50 and the return air chamber 31 in sequence, and then enter from the top and side of the main air chamber 11. In this way, the air intake from the top and side of the main air chamber 11 can blow away the dust on the clothes, pants and soles of the staff, and then intercept the dust through the filter assembly for purification, thereby realizing the overall effective cleaning of the staff.

[0037] The chamber body 10 is mainly made of stainless steel, which has the properties of corrosion resistance and wear resistance, thereby increasing the life of the dust removal air shower chamber.

[0038] The dust removal air shower room also includes an outer shell 30, and the chamber body 10, the first fan 20 and the second fan 21 are all located inside the outer shell 30, so that the chamber body 10, the first fan 20 and the second fan 21 are wrapped and carried by the outer shell 30, and it is also conducive to forming a circulating high-speed airflow in the outer shell 30.

[0039] Specifically, a return air chamber 31 is formed between the side of the outer shell 30 and the side of the chamber body 10, and an air inlet chamber 32 is formed between the top of the outer shell 30 and the top of the chamber body 10. The air inlet chamber 32 and the return air chamber 31 are connected. The first fan 20 is located in the air inlet chamber 32, and the positive pressure side of the first fan 20 faces the top of the chamber body 10. In this way, the first fan 20 can blow air from the top of the main air chamber 11 into the main air chamber 11 when it is running. The second fan 21 is located in the return air chamber 31, and the positive pressure side of the first fan 20 faces the top of the chamber body 10. The negative pressure side of the second fan 21 faces the return air chamber 12, so that the second fan 21 draws air from the return air chamber 12 when it is running, so that an airflow is generated from the side of the return air chamber 31 toward the side and top of the main air chamber 11. These airflows then enter the main air chamber 11 to blow away the dust on the clothes and pants of the staff, and at the same time cooperate with the sole cleaning mechanism 50 to remove the dust raised from the soles of the shoes and take it away, so as to intercept the dust through the filter component, thereby ensuring that the air entering the main air chamber 11 is clean.

[0040] Of course, in some embodiments, the outer shell 30 may not be provided, and the positive pressure side of the first fan 20 may be directly connected to the top of the main air chamber 11 by a pipeline, the positive pressure side of the second fan 21 may be connected to the side of the main air chamber 11 and the negative pressure side of the first fan 20 by a pipeline, and the negative pressure side of the second fan 21 may be connected to the side of the return air chamber 12 by a pipeline, so that air circulation is also feasible.

[0041] In this embodiment, the filter assembly includes a first filter 40, a second filter 41 and a third filter 42. The first filter 40 is located in the air inlet chamber 32, and the first filter 40 is located between the positive pressure side of the first fan 20 and the top of the main air chamber 11. The second filter 41 and the third filter 42 are both located in the return air chamber 31. The second filter 41 is located between the negative pressure side of the second fan 21 and the side of the return air chamber 12. The third filter 42 is located at a position corresponding to the side of the main air chamber 11. In this way, the second filter 41 can intercept the dust in the air entering the return air chamber 31 from the return air chamber 12 to achieve a primary purification treatment. Then the air enters the main air chamber 11 from the first filter 40 and the third filter 42 respectively. The first filter 40 and the third filter 42 once again intercept the dust in the air to achieve a secondary purification treatment of the air, thereby ensuring that the air entering the main air chamber 11 from the top and side of the main air chamber 11 is clean.

[0042] Among them, the second filter 41 can be a primary filter, the filtration efficiency of the primary filter is relatively low, and it usually has a certain filtration capacity for particles ≥5 microns, and the efficiency range is roughly G1 to G4 (classified according to EN779 or EN1822 standards), which can filter out about 50%-90% of particles above 5 microns. The materials of the primary filter are various, and the common ones are non-woven fabrics, foam plastics, metal mesh, nylon mesh, activated carbon filter materials, etc. These materials have certain mechanical strength and filtration performance, and the cost is relatively low. Since the primary filter mainly filters large particles, the clogging speed is relatively slow, so the service life is long. However, the specific service life depends on the dust concentration and maintenance of the actual working environment. The primary filter is usually designed to be washable or replaceable, and the maintenance is relatively simple. In a dusty environment, it is necessary to regularly check and clean or replace the filter material to maintain the filtration effect. In short, the primary filter plays an important role in air purification and environmental protection. By removing large particle pollutants in the atmosphere, it provides effective protection for subsequent filtration levels, and is also of great significance to improving air quality, protecting equipment, and optimizing the production environment.

[0043] The first filter 40 and the third filter 42 can both be high efficiency filters. A high efficiency filter (HEPA filter, i.e., High Efficiency Particulate Air Filter) is a filter device designed to capture extremely small particles in the air. It has a very high filtration efficiency and can effectively remove particles, bacteria, viruses, fungal spores, dust mites and other allergens in the air. According to the EN1822 standard, a high efficiency filter can capture at least 99.97% of 0.3 micron particles in the air. For higher-level models such as H13 and H14, the filtration efficiency can be as high as 99.995% or more. 0.3 microns is the standard particle size for testing filtration efficiency because particles of this size are the most difficult to capture. High efficiency filters usually use multiple layers of filter media, such as glass fiber, synthetic fiber, etc., and increase the filtration area through a complex folding design to achieve high efficiency filtration while maintaining low wind resistance. The frame, edge sealing and installation method (such as sealant) of the high efficiency filter are carefully designed to ensure that the air will not pass directly around the filter material to ensure filtration efficiency. High-efficiency filters are generally disposable and cannot be cleaned or reused, because the cleaning process may damage the filter material structure and reduce the filtration efficiency. In short, high-efficiency filters are an important guarantee for maintaining air quality and environmental cleanliness.

[0044] Combination Figure 2The shoe sole cleaning mechanism 50 includes a ventilation plate 51, a cleaning brush 52 and a driving assembly 53. The ventilation plate 51 is installed in the chamber body 10 to separate the internal space of the chamber body 10 into a main air chamber 11 and a return air chamber 12. The cleaning brush 52 is arranged in the return air chamber 12 and can extend into the main air chamber 11 through the ventilation plate 51. The driving assembly 53 is used to drive the cleaning brush 52 to move relative to the ventilation plate 51. In this way, after the staff enters the main air chamber 11, the ventilation plate 51 can play a role in supporting the weight of the staff. Since the cleaning brush 52 can extend into the main air chamber 11 through the ventilation plate 51, the cleaning brush 52 can brush off the dust carried by the soles of the staff when the driving assembly 53 drives the cleaning brush 52 to move relative to the ventilation plate 51.

[0045] Combination Figure 3 The driving assembly 53 includes a driving member 531 and a roller 532 which are transmission-connected. The cleaning brushes 52 are distributed on the outer surface of the roller 532. Both ends of the roller 532 can be installed on the inner wall of the return air chamber 12 through a bearing seat. The driving member 531 is used to drive the roller 532 to rotate, so that the roller 532 can drive the cleaning brush 52 to make a circular motion around its own central axis, so that different cleaning brushes 52 extend from the ventilation plate 51 into the main air chamber 11 to sweep the dust on the soles of the staff, thereby achieving the cleaning and brushing work of the soles.

[0046] Specifically, the driving member 531 includes a motor, and the output shaft of the motor is connected to the roller shaft 532 through a belt 533. For example, the output shaft of the motor is provided with a driving wheel, and a driven wheel is correspondingly provided at the end of the roller shaft 532. The belt 533 is wound around the driving wheel and the driven wheel, so that when the output shaft of the motor rotates, the roller shaft 532 can be driven to rotate.

[0047] The ventilation plate 51 is a stainless steel perforated plate, which has sufficient bearing strength and wear resistance, so that the ventilation plate 51 has a sufficient service life under the friction of the cleaning brush 52 and the trampling of the staff.

[0048] Of course, in some embodiments, the cleaning brush 52 can also be installed on some movable plates that can make horizontal reciprocating motion relative to the ventilation plate 51. The cleaning brush 52 can sweep the dust on the soles of the staff's shoes by driving the movable plate to move back and forth linearly through the driving member 531.

[0049] In summary, the present embodiment discloses a dust removal air shower room, in which a sole cleaning mechanism 50 is arranged in the room body 10, so that after the staff enters the main air chamber 11, the sole cleaning mechanism 50 can be operated to remove the dust on the soles. At the same time, since the main air chamber 11 and the return air chamber 12 are connected through the sole cleaning mechanism 50, the first fan 20 and the second fan 21 can realize high-speed air flow circulation from the main air chamber 11 through the sole cleaning mechanism 50 and the return air chamber 31 in sequence, and then enter from the top and sides of the main air chamber 11. In this way, the air intake from the top and sides of the main air chamber 11 can blow away the dust on the clothes, pants and soles of the staff, and then intercept the dust through the filter assembly for purification, thereby realizing the overall effective cleaning of the staff.
