[0034] This embodiment provides an air shower device, such as Figures 1-4As shown, the air shower device includes a box body 100, an air shower mechanism 200, an ion generator, a plurality of ion needles and a detection mechanism. An air shower room 110 is provided inside the box body 100. An air duct 140 is formed between the side wall of the air shower room 110 and the side wall of the box body 100. An air shower room 110 entrance and an air shower room 110 exit are provided at both ends of the air shower room 110. The air shower room 110 entrance and the air shower room 110 exit are provided with a first closed door 120 and a second closed door 130 respectively. The air shower mechanism 200 includes a filter assembly 210, an air duct inlet 220, a fan 230 and a plurality of nozzles 240. The air duct inlet 220 and the plurality of nozzles 240 are both provided on the side of the air shower room 110. On the wall, the filter assembly 210 and the fan 230 are both arranged in the air duct 140. The filter assembly 210 is used to filter the airflow in the air duct 140. The input end of the fan 230 is connected to the air duct inlet 220. The output end of the fan 230 is connected to the multiple nozzles 240 through the air duct 140. Each nozzle 240 is provided with an ion needle, which is electrically connected to the ion generator via a wire. The ion generator can enable the ion needle to release positively and negatively charged ions. With the help of the fan 230 and the multiple nozzles 240, the airflow with positively and negatively charged ions is blown toward the surface of the person or object in the air shower room 110, which can effectively remove dust and static electricity attached to the surface of the person or object. In addition, the detection end of the detection mechanism is located in the air shower room 110. The detection mechanism is used to detect the cleanliness of the surface of the person or object in the air shower room 110, ensuring that the person or object entering the clean room meets the cleanliness standards and effectively prevents pollutants from entering the dust-free environment.

[0035] Alternatively, as Figure 3 As shown, a first partition 141 and a second partition 142 are provided in the air duct 140, and the first partition 141 and the second partition 142 divide the air duct 140 into an air inlet chamber 143, an air outlet chamber 144 and an electrical chamber 145. The ion generator is arranged in the electrical chamber 145, and an air duct inlet 220 is provided on the side of the air inlet chamber 143 facing the air shower room 110, and a plurality of nozzles 240 are provided on the side of the air outlet chamber 144 facing the air shower room 110. A vent 1421 is provided on the second partition 142, and a fan 230 is located in the air inlet chamber 143. The input end of the fan 230 is connected to the air duct inlet 220, and the output end of the fan 230 is connected to the air outlet chamber 144 through the vent 1421. One end of the nozzle 240 is connected to the air outlet chamber 144, and the other end is connected to the air shower room 110, for blowing the airflow in the air outlet chamber 144 to the air shower room 110. The partitioned design of the air inlet chamber 143 and the air outlet chamber 144 ensures a clearer airflow path, effectively avoids airflow turbulence in the air duct 140, improves the stability and injection effect of the airflow, and thus enhances the dust removal and static electricity removal efficiency.

[0036] In addition, by setting the first partition 141 and the second partition 142, the air inlet chamber 143, the air outlet chamber 144 and the electrical chamber 145 are separated. The electrical chamber 145 is specifically used to place the ion generator to avoid direct contact between the ion generator and the airflow, thereby improving the safety of the electrical system.

[0037] Alternatively, as Figure 3 As shown, an air collecting hood 250 is provided within the air outlet chamber 144. The air collecting hood 250 includes an air induction portion 251 and an air outlet portion 252. The air induction portion 251 covers the air vent 1421, and the air outlet portion 252 has an air induction outlet, which is directed toward the multiple nozzles 240. The air collecting hood 250 reduces diffusion losses of the air flow within the air outlet chamber 144 by concentrating and guiding the airflow, allowing the power of the fan 230 to be used more efficiently, thereby reducing the energy consumption of the air shower equipment and improving the operating efficiency of the fan 230.

[0038] Specifically, the bottom of the air collecting hood 250 is formed with an air inlet 251 having a trapezoidal cross-section, and the upper middle portion of the air collecting hood 250 is formed with an air outlet 252 having a rectangular cross-section. The air inlet 251 of the air collecting hood 250 covers the vent 1421, and the front side of the air outlet 252 is open to form an air outlet, which transversely intersects with each nozzle 240. In this embodiment, air shower mechanisms 200 are provided on both sides of the air shower room 110, forming a unidirectional circulating airflow from top to bottom on both sides of the air shower room 110, allowing dust cleaning and static electricity removal on both sides of the personnel inside to be processed simultaneously, further improving the cleaning efficiency of the air shower room 110.

[0039] Optionally, the filter assembly 210 includes an outlet filter 211. The outlet portion 252 is provided with a first drawer guide groove 2521. The outlet filter 211 is slidably inserted into the first drawer guide groove 2521. The outlet filter 211 can filter the airflow entering the air shower room 110, effectively removing dust and particulate matter from the airflow, ensuring high cleanliness of the airflow into the air shower room 110, and effectively improving the dust removal and static electricity removal effects of the equipment. The outlet filter 211 can be slid into and out of the drawer guide groove. When the user needs to replace or clean the filter, there is no need to disassemble other components. The filter can be simply pulled out of the first drawer guide groove 2521, significantly improving maintenance efficiency.

[0040] Alternatively, as Figure 3 and Figure 4As shown, the filter assembly 210 also includes an air inlet filter 212. The air duct inlet 220 is provided with a mesh plate, and the air inlet filter 212 is located on the side of the mesh plate facing the air duct 140. The air inlet filter 212 performs preliminary filtration on the airflow entering the air duct 140, effectively removing large particles of dust and impurities, preventing these pollutants from entering the air duct 140 and affecting the normal operation of the equipment. Subsequently, the airflow is further filtered by the air outlet filter 211, ensuring that the airflow entering the air shower 110 is highly clean, thereby improving the dust removal effect.

[0041] Optionally, in this embodiment, a second drawer guide groove is provided on the side of the air duct inlet 220 facing the air duct 140, and the air inlet filter 212 is inserted into the second drawer guide groove and covers the air duct inlet 220. By setting the second drawer guide groove, the air inlet filter 212 can be slidably inserted and removed, which simplifies the replacement process of the air inlet filter 212 and reduces the downtime of the equipment.

[0042] In other embodiments, a first magnetic component is provided on the side of the air duct inlet 220 facing the air duct 140, and a second magnetic component is provided on the air inlet filter 212. The second magnetic component can be adsorbed on the first magnetic component. The adsorption characteristics of the magnetic component are utilized to facilitate the installation and disassembly of the air inlet filter 212, and can ensure that the air inlet filter 212 fits tightly with the air duct inlet 220, preventing the airflow from bypassing the air inlet filter 212 and directly entering the air duct 140, thereby improving the filtering effect.

[0043] Optionally, the box body 100 is made of cold-rolled steel plate, and an anti-static paint layer is provided on the surface of the cold-rolled steel plate. The anti-static paint layer can effectively prevent the generation and accumulation of static electricity, further improving the air cleanliness of the air shower room 110.

[0044] In other embodiments, the box body 100 is made of 304 stainless steel. The surface of 304 stainless steel is smooth, easy to clean, and not easy to accumulate dirt and bacteria. In addition, 304 stainless steel has good corrosion resistance and can effectively resist the erosion of various chemical substances, thereby increasing the service life of the air shower equipment.

[0045] Optionally, the first closed door 120 and the second closed door 130 are respectively hinged to the box body 100. The hinged design allows the closed doors to be easily opened and closed, making it convenient for users to enter and exit the air shower room 110, thereby improving cleaning efficiency.

[0046] Optionally, the air shower device further includes a controller and a display screen. The air shower mechanism 200, ion generator, detection mechanism, and display screen are all electrically connected to the controller. The display screen is used to display the operating status of the air shower device, including wind speed, air filtration status, static elimination effect, etc. The controller can centrally control the air shower mechanism 200, ion generator, and detection mechanism of the air shower device. The user only needs to perform simple operations and settings through the display screen, which simplifies the operating process and improves ease of use.

[0047] It should be noted that the controller can be a centralized or distributed controller. For example, the controller can be a single single-chip microcomputer or a distributed plurality of single-chip microcomputers. The control program can be run in the single-chip microcomputer, so that the air shower mechanism 200, the ion generator, and the detection mechanism can work together to remove dust and static electricity from the surface of people or objects in the air shower room 110. The control program running in the single-chip microcomputer is a technical means well known to those skilled in the art and will not be elaborated here.

[0048] Optionally, the detection mechanism is an electrostatic field tester, which is used to detect the electrostatic voltage on the surface of people or objects in the air shower room 110 to ensure that the electrostatic voltage on the outer surface of people passing through the air shower room 110 meets the safety standards for entering the clean room.

[0049] Optionally, the air shower equipment also includes an alarm component, which is electrically connected to the electrostatic field tester. The alarm component includes an alarm light and / or a buzzer alarm. Once the electrostatic voltage is detected to exceed a set threshold, the alarm light flashes and the buzzer alarm sounds an alarm to remind the staff to take necessary static elimination measures to reduce the risk.

[0050] Optionally, a sterilization lamp 260 is provided on the top of the air shower room 110 to achieve internal lighting while completing the sterilization of the personnel's body surface, further improving the cleaning quality of the air shower room 110 equipment.
