Technical Field
[0001] This utility model relates to the field of air shower mechanisms, and in particular to an air shower mechanism with dual filtration function. Background Technology
[0002] In many fields with extremely high requirements for environmental cleanliness, such as modern industrial production, scientific experiments, and medical treatment, including electronic chip manufacturing, high-precision instrument research and development, and sterile drug production, preventing dust, impurities, and other contaminants from entering the working environment is crucial. Air showers, as key equipment for ensuring a clean environment, effectively clean personnel or goods before they enter the clean area, removing surface contaminants and thus reducing sources of contamination within the clean area.
[0003] Existing air shower systems typically consist of basic components such as a fan, a single-stage filter, an air shower chamber, nozzles, and a control system. Their working principle generally involves the fan drawing in outside air, which is then filtered through the single-stage filter to remove some dust particles before being sent into the air shower chamber. The filtered air is then sprayed at high speed through nozzles on the inner wall of the air shower towards personnel or goods entering the chamber, using the impact force of the airflow to blow off any dust adhering to their surfaces.
[0004] However, traditional air showers are not comprehensive enough for cleaning personnel and goods. They often only clean the exposed surfaces of personnel's bodies to a certain extent, but cannot effectively deal with areas such as shoe soles that are prone to accumulating dirt. As a result, dust carried by personnel's shoes can easily be stirred up when they walk in the clean area, thus contaminating the clean environment.

[0037] Referring to Figure 1 - Figure 5 The dust removal assembly includes a hydraulic rod 17, the hydraulic rod 17 is fixedly connected to the inside of the ventilation cavity 6, the ventilation opening 4 is provided with a cleaning brush 18 on the side wall, the cleaning brush 18 is used for cleaning the surface of the ventilation opening 4, the output end of the hydraulic rod 17 is connected with the cleaning brush 18, the side wall of the cleaning brush 18 is fitted with the side wall of the ventilation opening 4, a collecting box 19 is slidably connected in the box 1, the collecting box 19 is used for temporarily storing the dust generated by cleaning the ventilation opening 4, preventing the dust from spreading in the air shower room, a fixed column 20 is fixedly connected to the side wall of the box 1, a connecting plate 21 is rotatably connected to the side wall of the fixed column 20, a clamping block 22 is slidably connected in the connecting plate 21, the clamping block 22 plays a role in fixing the collecting box 19, the side wall of the clamping block 22 is slidably connected in the collecting box 19, a spring 23 is fixedly connected in the connecting plate 21, and the side wall of the spring 23 is fixedly connected to the side wall of the clamping block 22;
[0038] To prevent the ventilation opening 4 from being blocked by dust and sundries in long-term use, the ventilation opening 4 is a channel for air exchange between the inside of the air shower and the outside or internal air circulation, and its unobstructedness directly affects the normal operation of the air shower. The hydraulic rod 17 is started to drive the cleaning brush 18 to move. The hydraulic rod 17 can provide stable and controllable power, so that the cleaning brush 18 can smoothly reciprocate within the preset stroke range, thereby ensuring comprehensive cleaning of the ventilation opening 4.

[0039] Working principle: The worker stands in the box body 1. At this time, the fan 5 sends the air shower gas into the ventilation cavity 6, and then filters and purifies through the filter 7, and is delivered to the side wall nozzle one 3 and the top nozzle two 9 to spray towards the personnel. The attached dust, hair and other pollutants are blown off. The motor 15 is started to drive the gear one 13 to rotate. The gear one 13 is engaged with the gear two 14, thereby driving the rotating shaft 11 to rotate and driving the brush 12 to rotate. The brush 12 cleans the soles of the personnel through the square groove 10. The fallen dust enters the inside of the dust collection box 16, which can be extracted for cleaning.
[0040] To prevent the ventilation opening 4 from being blocked by dust and sundries in long-term use, the hydraulic rod 17 is started to drive the cleaning brush 18 to move. The bristles on the cleaning brush 18 continuously clean the surface of the ventilation opening 4. The dust swept falls into the inside of the collection box 19. When the collection box 19 needs to be cleaned, the connecting plate 21 is rotated, the clamping block 22 is extruded into the inside of the connecting plate 21 to extrude the spring 23, the clamping block 22 can be tightly matched with the corresponding clamping groove on the collection box 19 in the normal state to fix the collection box 19. When extruded by external force, the clamping block 22 is retracted into the connecting plate 21 and compresses the spring 23. The spring 23 stores elastic potential energy when the clamping block 22 is extruded, which provides power for the subsequent resetting of the clamping block 22. The fixing of the collection box 19 is cancelled. The handle is convenient for workers to hold and apply force to extract the collection box 19 from the air shower for cleaning.
