Technical Field

[0001] This utility model relates to the field of cleanroom equipment technology, and in particular to an anti-static cleanroom air shower system. Background Technology

[0002] When entering workshops or places with high requirements for cleanliness and static electricity, it is necessary to go through a complete air shower system to remove dust / foreign objects carried by personnel and to detect and release static electricity on personnel.

[0003] In existing technologies, the electrostatic discharge and detection in many dust removal systems are still done manually and recorded, with release based on subjective judgment, which has a large error. This results in static electricity adsorbing floating dust and bringing it into the workshop after the air shower. Before entering the air shower room, there is a lack of cleaning of dust from the soles of shoes. During the air shower dust removal process inside the air shower room, it cannot be guaranteed that personnel can be fully showered. Utility Model Content

[0024] Please see Figures 1 to 3The anti-static cleanroom air shower system provided in one embodiment of this utility model includes a cleaning device 1, an anti-static zone 2, and an air shower zone 3. The cleaning device 1 removes large particles of dust adhering to the cleanroom clothing worn by personnel. The anti-static zone uses an anti-static discharge device 21 and a facial recognition system 22 to completely release static electricity from personnel and performs facial recognition and recording via the facial recognition system 22 to prevent static electricity from adsorbing dust onto the cleanroom clothing. Then, a shoe brush 31 cleans the dust from the soles of the personnel's shoes. After cleaning, the personnel enter the air shower 32 and undergo full-body dust removal through the S-shaped air shower channel 325 inside the air shower 32, thus entering the workshop without dust and maintaining a dust-free environment inside the workshop.

[0025] See Figure 1 The cleaning device 1 is installed on the wall of the changing room and includes a fixing plate 11 and a dust-removing pad 12. The fixing plate 11 has mounting holes around its perimeter, through which it is fixed to the wall. The dust-removing pad 12 is attached to the outer side of the fixing plate 11. After putting on the cleanroom suit, the person rolls around on the dust-removing pad 12 to remove large dust particles from the suit. The dust-removing pad 12 is attached to the fixing plate 11 for easy replacement later. Furthermore, in this embodiment, the dust-removing pad 12 is U-shaped. This U-shaped structure achieves the same full-body dust removal effect as a rectangular structure after the person rolls around, saving manufacturing costs and providing a certain aesthetic appeal. Additionally, the fixing plate 11, which matches the dust-removing pad 12, is also U-shaped.

[0026] See Figure 2The anti-static cleanroom is divided into a static removal zone 2 and an air shower zone 3. The static removal zone 2 is equipped with a static discharge device 21, a facial recognition system 22, and an electric gate 4. Personnel can undergo facial recognition via the facial recognition system 22, sending the recognition information to the system. The static discharge device 21 then releases and detects static electricity, simultaneously sending the detection information to the system. Once both the facial recognition and static discharge detection information are satisfactory, the system controls the electric gate 4 to open, allowing personnel to enter the next air shower zone 3. This automated detection process avoids errors caused by manual inspection and the loopholes in subjective judgment, improving the effectiveness of static discharge. It should be noted that in this embodiment, the static discharge device 21 is a foot-operated static discharge device 21, and the static discharge device 21 and the facial recognition system 22 are integrated. Specifically, the facial recognition system 22 is installed on one side directly above the foot-operated static discharge device 21, forming a single unit. Personnel can simultaneously perform static discharge and detection during facial recognition, thereby accelerating the detection process. Of course, the electrostatic discharge device 21 can also be of other structures, such as manual touch type or wristband type; in some embodiments, the electrostatic discharge device 21 and the face recognition system 22 can also be separate. Personnel can first undergo face recognition. After the recognition is successful, the electrostatic discharge device 21 can release and detect static electricity. When the static electricity release is qualified, the electrostatic discharge device 21 controls the electric gate 4 to open, and the personnel can enter the next air shower area 3.

[0027] See Figures 3 to 4 The air shower area 3 is equipped with an air shower chamber 32 and a shoe brush 31. The shoe brush 31 is located on one side of the entrance end of the air shower chamber 32. The shoe brush 31 includes a housing 311 for personnel to step on. Inside the housing 311, there is a track and a motor that drives the track to rotate. The track and the motor cooperate to form a transmission belt structure with a length equivalent to that of the housing 311. The outer surface of the track is covered with brushes 314. The upper side of the housing 311 has multiple slots 312 along the direction of track rotation. The slots 312 are used to avoid the protrusion of the brushes 314, making it convenient to directly clean the soles of the shoes. The upper side of the housing 311 also has through holes 313 for the brushes 314 to extend out, making it convenient to clean the contact surface between the soles of the shoes and the housing 311 where they are stepped on. The lower end of the housing 311 has a second water tank. The brushes 314 are cleaned in the water tank at the lower end by the rotation of the track, ensuring that the surface of the brushes 314 is clean. Furthermore, in this embodiment, the shoe brush 31 is provided with an induction switch for controlling the operation of the motor at one end near the static elimination area 2. When a person steps on the shoe brush 31, the induction switch controls the motor to turn on and clean the soles of the shoes.

[0028] See Figure 2The air shower 32 has an entrance door 321 and an exit door 322 at both ends. The air shower 32 contains an air shower space, which is enclosed by two side walls 323 with blowing holes, a top with a fan filter unit for vertical blowing, a bottom plate with several small holes at intervals, and the entrance door 321 and exit door 322. A first water tank is located below the bottom plate. Several obstruction plates are installed within the air shower space, and these obstruction plates are spaced and staggered on the side walls 323, dividing the air shower space into an S-shaped air shower channel 325. Specifically, when personnel enter the air shower 32, the dust on their cleanroom suits is blown away through the blowing holes on the side walls 323, and then the dust floating in the air is filtered by the fan filter unit at the top. Dust is blown onto the bottom plate and falls through small holes into the first water tank at the bottom, where it is absorbed, thus achieving dust removal through air showering. Since the air shower holes can only blow out from the side walls 323, they cannot perform full-body dust removal on personnel. Therefore, several obstruction plates 324 are set on the side walls 323. By setting the obstruction plates 324, the air shower space is divided into an S-shaped air shower channel 325. As personnel walk along the air shower channel 325, they automatically turn around as the direction of the S-shaped air shower channel 325 changes, thereby achieving 360° full-body air showering and improving the dust removal effect. Furthermore, in this embodiment, the width of the obstruction plate is greater than half the distance between the two side walls 323. This design extends the air shower time after turning around, making the air showering more thorough. It should also be noted that, in order to prevent dust floating in the air from being blown onto the base plate by the fan filter unit and thus unable to fall into the holes, the spacing between the holes is set between 0.5mm and 2mm. This ensures that the dust can fall into the holes and be absorbed in the first water tank. In this embodiment, the spacing between the holes is set to 1mm. This ensures the structural strength of the base plate and reduces dust accumulation. Optionally, the spacing between several holes is 1mm.

[0029] In summary, the anti-static dust-free air shower system in the above embodiments of this utility model avoids errors caused by manual detection and release of static electricity by setting up an electrostatic discharge device and a facial recognition system in the static discharge area, which not only improves the effect of static discharge but also increases work efficiency and reduces labor costs. By setting up a shoe brush in the air shower area, areas of the soles of personnel's shoes that are difficult to be blown clean can be cleaned, further improving the quality of dust-free operation. By setting up a baffle plate in the air shower room to divide the air shower space into an S-shaped air shower channel, the system can achieve full-body air shower dust removal for personnel, resulting in better dust removal effect.
