Description

Technical Field

[0001] The invention relates to the technical field of air shower rooms, and in particular to a modular air shower room. Background Art

[0002] Air shower room is a kind of equipment widely used in dust-free clean environment. Its main function is to remove dust particles carried by people or objects entering the clean area through clean airflow after high-efficiency filtration, so as to prevent pollution sources from entering the clean environment, thereby ensuring the cleanliness of the environment.

[0003] Existing air shower rooms generally consist of an enclosed space with air nozzles installed on both sides and two doors. When a worker opens the front door to enter the air shower room, the worker then closes the front door and enters the inspection range; after the detector detects the worker, it locks the front door and automatically starts the fan to perform air showering; after the air shower is completed, the rear door lock is automatically opened, and the worker opens the rear door to walk out of the air shower room and closes the rear door.

[0004] However, when the existing air shower room is working, all fans work at the same time. The larger the area of ​​the air shower room, the more workers can enter, but the energy consumption of the fans is also higher. If the area of ​​the air shower room is too small, it will cause queues. A large air shower room requires workers to take time to walk to the sensing area before starting the air shower, which is not only troublesome but also time-consuming. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art. The present invention solves the problem that the existing air shower room cannot control the operation of the fan according to the number of workers entering, resulting in high energy consumption of the fan, and the small area of ​​the air shower room will cause queuing, wasting a lot of time; the air shower room can control the movement of the back door according to the number of workers entering, thereby controlling the number of fan operations, saving energy consumption of the air shower room, and no queuing is required, saving a lot of time, and at the same time, greatly improving the efficiency of the air shower room.

[0006] In order to solve the above technical problems, the present invention is implemented by adopting the following technical solutions: A modular air shower room comprises: an air shower chamber, a front door, an air nozzle, a return air outlet, a partition and a rear door; the front door is installed at the front end of the air shower chamber, a plurality of air nozzles are installed on the inner wall of the air shower chamber, a plurality of return air outlets are installed on the inner wall of the air shower chamber, the return air outlets are located below the air nozzles, a plurality of partitions are installed in the air shower chamber, a plurality of the partitions separate the plurality of air nozzles and the return air outlets into a plurality of air chambers, and a rear door is installed inside the air shower chamber; it also includes a moving mechanism, the moving mechanism is installed inside the air shower chamber, and the moving mechanism is located at the bottom of the rear door, the moving mechanism is stepped on a pedal downward, the pedal moves downward and drives the first driving rods on both sides to rotate through the rack, the first driving rod drives the rotating shaft to rotate through the belt, and the rotating shafts on both sides rotate simultaneously to move the sliding nut seat on the rotating shaft, thereby driving the rear door to move, and at the same time, the compression spring at the bottom of the pedal is compressed, the first electromagnet and the second electromagnet are mutually adsorbed, and then the air is sprayed out from the air nozzle.

[0007] These air nozzles are used to effectively remove dust particles attached to the surface of people or objects; multiple partitions isolate multiple air nozzles and return air outlets into multiple independent air chambers, each of which can independently generate and circulate airflow, thereby further improving the air shower effect.

[0008] When the pedal is stepped on, the pedal moves downward and drives the first driving rods on both sides to rotate through the rack structure; the first driving rods further drive the rotating shaft to rotate through the connected belt, and at the same time, the rotating shafts on both sides rotate synchronously, so that the sliding nut seat fixed on the rotating shaft moves along the guide rail direction, thereby realizing the forward and backward movement of the rear door.

[0009] During this process, the compression spring at the bottom of the pedal is compressed. In addition, the moving mechanism is also designed with a first electromagnet and a second electromagnet. The two electromagnets are attracted to each other to assist in fixing and locking.

[0010] The modular air shower room can control the movement of the rear door according to the flow of people, thereby controlling the size of the air shower room space. At the same time, the pedal drive not only saves energy, but also enhances the reliability and durability of the system, making it suitable for high-frequency use scenarios. The overall structure improves the working efficiency of the air shower room.

[0011] Preferably, the moving mechanism includes: a base, a pedal, a first driving rod, a second driving rod, a rotating shaft, a support column, a compression spring, a cylinder and a rack; the base is installed at the bottom of the air shower chamber, and a plurality of pedals are installed in a linear array inside the base, two first driving rods are installed inside the base, and the two first driving rods are located below the two ends of the pedal, two second driving rods are installed inside the base, and the two second driving rods are located on the outside of the two first driving rods, and the two second driving rods are located on the same plane as the two first driving rods, two rotating shafts are installed inside the base, and the two rotating shafts are located obliquely above the outside of the two second driving rods, a support column is installed at the center of the bottom of the pedal, a compression spring is installed at the bottom of the pedal, and the compression spring is located on the outside of the support column, a cylinder is installed in the base, and the support column is slidably located inside the cylinder, and racks are respectively installed at both ends of the pedal, and the racks are respectively located between the first driving rod and the second driving rod on both sides.

[0012] The base is the bearing structure of the entire mobile mechanism. It is installed at the bottom of the air shower chamber and plays a role of fixing and supporting. The pedal is the operating component that the worker directly steps on. It is located on the surface of the base, and its bottom center is connected to the inside of the base through the support column. The compression spring can be compressed when the worker steps on the pedal, providing rebound force to achieve the pedal reset. The support column is slidably set in the cylinder inside the base. The cylinder plays a role in guiding and stabilizing the movement of the support column, ensuring that the pedal moves up and down smoothly and reliably.

[0013] It should be noted that when the pedal moves downward, the first drive rod is driven to rotate through the inner side of the rack, and the power is transmitted to the rotating shaft, thereby driving the rear door to move. When the pedal moves upward, the second drive rod is driven to rotate and the power is transmitted to the rotating shaft, thereby driving the rear door to reset. When the first drive rod rotates, the second drive rod will not rotate. Conversely, when the second drive rod rotates, the first drive rod will not rotate.

[0014] Preferably, a plurality of first rotating teeth are installed in a linear array on the first driving rod, a plurality of second rotating teeth are installed in a linear array on the second driving rod, and the first rotating teeth and the second rotating teeth are respectively meshed with two sides of the rack.

[0015] Specifically, the first driving rod is provided with a plurality of first rotating teeth in a linear array along its length direction, and the first rotating teeth are arranged evenly to ensure that each gear can be precisely meshed with the adjacent rack; similarly, the second driving rod is also provided with a plurality of second rotating teeth in a linear array along its length direction, and the positions of the second rotating teeth correspond to the positions of the first rotating teeth and mesh with the two sides of the rack. With such an arrangement, when the rack moves in one direction, only one of them can be driven to rotate.

[0016] Preferably, a first rotating wheel is disposed on one end of the first driving rod, a second rotating wheel is disposed on one end of the second driving rod, and the first rotating wheel and the second rotating wheel are not located on the same side.

[0017] Specifically, a first rotating wheel is installed at one end of the first driving rod, and a second rotating wheel is installed at one end of the second driving rod. It is worth noting that the two rotating wheels are not located on the same side, but are respectively arranged at different positions at both ends of the driving rod, thereby achieving a more reasonable spatial layout and a more balanced transmission mechanism.

[0018] Preferably, the two rotating shafts are provided with threads, and the spiral directions of the two threads are opposite, and the rotating shafts are provided with sliding nut seats, and the sliding nut seats cooperate with the threads.

[0019] It should be noted that when the pedal moves downward, the first drive rod rotates, and drives the rotating shafts on both sides to rotate at the same time. In order to enable the sliding nut seats on the rotating shafts to move in one direction at the same time, the threads on the rotating shafts on both sides must be designed in opposite directions. In this way, when the two rotating shafts rotate at the same time, the sliding nut seats can move in the same direction at the same time, thereby ensuring the movement of the rear door.

[0020] Preferably, a first ratchet is disposed on one end of the rotating shaft, and a second ratchet is disposed on the other end, and the one-way driving directions of the first ratchet and the second ratchet are opposite, and the first ratchet and the second ratchet are connected to the first rotating wheel and the second rotating wheel respectively through belts. It should be noted that the first ratchet and the second ratchet at both ends of the rotating shaft are respectively connected to the first driving rod and the second driving rod, and due to the different working orders, both the first driving rod and the second driving rod need to drive the rotating shaft to rotate. When the first driving rod rotates, the rotating shaft rotates. In order to prevent the rotating shaft from interfering with the second driving rod, the first ratchet and the second ratchet at both ends of the rotating shaft need to cooperate with each other. When the first driving rod drives the rotating shaft to rotate, due to the action of the second ratchet, the rotating shaft will not drive the second driving rod to rotate. Conversely, when the second driving rod drives the rotating shaft to rotate, due to the action of the first ratchet, the rotating shaft will not drive the first driving rod to rotate, thereby realizing the reasonable distribution of power and greatly improving the overall transmission efficiency.

[0021] Preferably, a first electromagnet is installed at the bottom of the support column, and a second electromagnet is installed at the bottom of the cylinder.

[0022] The first electromagnet and the second electromagnet can change the magnetism between the two so that the support column and the cylinder are fixed and locked to each other to prevent the subsequent pedals from moving downward after the workers pass through the rear door, thereby avoiding the rear door from moving again. At the same time, the pedal that has been pressed down is locked to prevent the pedal from moving upward after the workers leave the pedal, thereby causing the rear door to move. Only after all the workers have walked out of the air shower room will the first electromagnet and the second electromagnet be powered off, allowing the pedal and the rear door to return to their original positions.

[0023] Preferably, the rack includes a connecting block, a first tooth, a first spring, a second tooth and a second spring, the top of the connecting block is connected to the bottom of the pedal, one end of the first spring is installed on the inner side of the connecting block, the first tooth is slidably installed on the inner side of the connecting block, and the first tooth is connected to the first spring, one end of the second spring is installed on the outer side of the connecting block, the second tooth is slidably installed on the outer side of the connecting block, and the second tooth is connected to the second spring, and the tooth tips of the first tooth and the second tooth are in opposite directions.

[0024] Since the depression and rise of the pedal will drive different mechanical structures, in order to prevent interference between the various mechanical structures, the first tooth and the second tooth on the rack need to be set as telescopic teeth. When the rack moves downward, the first tooth will drive the first drive rod to rotate, and at the same time, the second tooth will be compressed into the connecting block. Conversely, when the rack moves upward, the second tooth will drive the second drive rod to rotate, and at the same time, the first tooth will be compressed into the connecting block. When the pedal moves downward or upward, the first tooth and the second tooth will be driven to return to their original positions by the first spring and the second spring.

[0025] Preferably, the height value of the pedal moving downward is equal to the distance value of the rear door moving backward, and the distance value of the rear door moving backward is equal to the width value of the pedal.

[0026] Specifically, the height value of the pedal moving downward is equal to the distance the rear door moves backward. This is to ensure that when the first worker enters, the rear door will move backward a certain distance to reserve the next pedal for the worker and be able to move forward further. At the same time, space is also left at the back for the second worker to enter.

[0027] Preferably, the top of the front door is provided with electric wires, and the two sides of the rear door are provided with through-beam sensors. The electric wires are used to supply power to the rear door and the components installed thereon, and the through-beam sensors are used to detect whether the front door is closed, thereby controlling the operation of the air nozzles of the corresponding modules inside the air shower room, which greatly improves the efficiency of the air shower room.

[0028] Compared with the prior art, the present invention has the following beneficial effects: 1. The present application provides a moving mechanism at the bottom of the air shower chamber, and through the cooperation between the pedal on the moving mechanism and the rear door, the pedal moves downward, driving the first driving rod to rotate and driving the rotating shaft to rotate, so that the rear door on the rotating shaft moves, and the air volume inside the air shower room is controlled according to the change of the flow of people, thereby saving the energy consumption of the air shower room, not only avoiding energy waste but also allowing the flow of people to pass quickly, saving a lot of time, and at the same time greatly improving the working efficiency of the air shower room.

[0029] 2. The present application provides a second tooth on the pedal rack, and cooperates with the compression spring at the bottom of the pedal, so that the pedal drives the rear door to return to its original position during the resetting process, and the first electromagnet and the second electromagnet at the bottom of the pedal prevent the pedal from being compressed after air showering, preventing the rear door from moving when the worker walks out of the air shower room, thereby saving energy consumption and improving the efficiency of the air shower room.

[0030] 3. The present application provides a back-fire sensor on the rear door, which detects the front and rear switch states through the back-fire sensor, thereby controlling the start-up of the air nozzles on the air shower room, so that the entire air shower room can be modularly operated according to the number of people, thereby greatly saving the energy consumption of the fan and improving the working efficiency of the air shower room.

DETAILED DESCRIPTION

[0041] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0042] like Figures 1 to 9 As shown, a modular air shower room comprises: an air shower chamber 1, a front door 2, an air nozzle 3, a return air outlet 4, a partition 5 and a rear door 6; the front door 2 is installed at the front end of the air shower chamber 1, a plurality of air nozzles 3 are installed on the inner wall of the air shower chamber 1, a plurality of return air outlets 4 are installed on the inner wall of the air shower chamber 1, and the return air outlets 4 are located below the air nozzles 3; a plurality of partitions 5 are installed in the air shower chamber 1, and the plurality of partitions 5 separate the plurality of air nozzles 3 and the return air outlets 4 into a plurality of air chambers; a rear door 6 is installed inside the air shower chamber 1; and a moving mechanism 7 is also included, and the moving mechanism 7 is installed on The moving mechanism 7 is located inside the air shower chamber 1 and at the bottom of the rear door 6. The moving mechanism 7 steps on the pedal 72 downward, and the pedal 72 moves downward and drives the first driving rods 73 on both sides to rotate through the rack 79. The first driving rod 73 drives the rotating shaft 75 to rotate through the belt 8. The rotating shafts 75 on both sides rotate at the same time to move the sliding nut seat 61 on the rotating shaft 75, thereby driving the rear door 6 to move. At the same time, the compression spring 77 at the bottom of the pedal 72 is compressed, and the first electromagnet 761 and the second electromagnet 781 are attracted to each other, and then the wind is ejected from the air nozzle 3.

[0043] When the user steps on the pedal 72, the pedal 72 moves downward, and the rack 79 structure drives the first driving rods 73 on both sides to rotate. The first driving rods 73 transmit power through the connected belt 8 to drive the rotating shaft 75 to rotate synchronously; the synergistic effect of the rotating shafts 75 on both sides further enables the sliding nut seat 61 fixed on the rotating shaft 75 to move smoothly, thereby realizing the forward and backward movement of the rear door 6.

[0044] In this process, the compression spring 77 at the bottom of the pedal 72 is compressed and stores potential energy, and then the pedal 72 returns to its initial position. In addition, the first electromagnet 761 and the second electromagnet 781 are designed in the moving mechanism 7, and the two are attracted to each other, providing additional fixing and locking functions, which effectively improves the safety and stability of the system.

[0045] like Figure 4 and Figure 5 As shown, the moving mechanism 7 includes: a base 71, a pedal 72, a first driving rod 73, a second driving rod 74, a rotating shaft 75, a supporting column 76, a compression spring 77, a cylinder 78 and a rack 79; the base 71 is installed at the bottom of the air shower chamber 1, a plurality of pedals 72 are installed in a linear array inside the base 71, two first driving rods 73 are installed inside the base 71, the two first driving rods 73 are located below the two ends of the pedal 72, two second driving rods 74 are installed inside the base 71, the two second driving rods 74 are located outside the two first driving rods 73, and the two second driving rods 74 are located outside the two first driving rods 73. 4 is located on the same plane as the two first driving rods 73, two rotating shafts 75 are installed inside the base 71, and the two rotating shafts 75 are located obliquely above the outer sides of the two second driving rods 74, a supporting column 76 is installed at the center of the bottom of the pedal 72, a compression spring 77 is installed at the bottom of the pedal 72, and the compression spring 77 is located outside the supporting column 76, a cylinder 78 is installed in the base 71, and the supporting column 76 is slidably located inside the cylinder 78, racks 79 are installed at both ends of the pedal 72, and the racks 79 are respectively located between the first driving rod 73 and the second driving rod 74 on both sides.

[0046] When the first worker steps on the pedal 72, the pedal 72 will move downward, causing the rack 79 at the bottom of the pedal 72 to move downward as well. The first tooth 792 inside the rack 79 meshes with the first rotating tooth 731 on the first driving rod 73, pushing the first rotating tooth 731 to rotate, thereby driving the first driving rods 73 on both sides to rotate. The first driving rod 73 pushes the first rotating wheel 732 to rotate, and transmits the power to the first ratchet 752 through the belt 8, driving the rotating shaft 75 to rotate. The rotating shafts 75 on both sides rotate synchronously, causing the sliding nut seat 61 on the rotating shaft 75 to move backward together, thereby pushing the rear door 6 to move backward by a distance of the width of the pedal 72. At this time, the first electromagnet 761 in the support column 76 and the second electromagnet 781 in the cylinder 78 are energized, generating a magnetic force that attracts each other, preventing the pedal 72 from returning to its original position.

[0047] When the second worker enters, the first worker steps on the second pedal 72, causing the second pedal 72 to move downward, thereby causing the rear door 6 to move backward again. If more workers enter later, the first worker will step on the third pedal 72, the second worker will step on the second pedal 72, the third worker will step on the first pedal 72, and so on, and the rear door 6 will also move accordingly. When no workers enter, the front door 2 is closed, and the air nozzle 3 inside the air shower chamber 1 starts to work, spraying a large amount of airflow for air showering.

[0048] like Figure 6 As shown, a plurality of first rotating teeth 731 are installed in a linear array on the first driving rod 73, and a plurality of second rotating teeth 741 are installed in a linear array on the second driving rod 74, and the first rotating teeth 731 and the second rotating teeth 741 are respectively engaged with two sides of the rack 79.

[0049] When the pedal 72 moves downward, the first rotating tooth 731 is driven to rotate by the first tooth 792 on the rack 79, thereby rotating the first driving rod 73. When the pedal 72 moves upward, the second rotating tooth 741 is driven to rotate by the second tooth 794 on the rack 79, thereby rotating the second driving rod 74.

[0050] like Figure 7 As shown, a first rotating wheel 732 is disposed on one end of the first driving rod 73, a second rotating wheel 742 is disposed on one end of the second driving rod 74, and the first rotating wheel 732 and the second rotating wheel 742 are not located on the same side.

[0051] When the pedal 72 moves downward, the first tooth 792 on the rack 79 will drive the first drive rod 73 to rotate, and drive the first rotating wheel 732 to rotate, and the first rotating wheel 732 needs to transmit power to the first ratchet 752 on the rotating shaft 75 through the belt 8, and drive the rotating shaft 75 to rotate through the first ratchet 752; similarly, when the pedal 72 moves upward, the second tooth 794 on the rack 79 will drive the second drive rod 74 to rotate, and drive the second rotating wheel 742 to rotate, and the second rotating wheel 742 needs to transmit power to the second ratchet 753 on the rotating shaft 75 through the belt 8, and drive the rotating shaft 75 to rotate through the second ratchet 753.

[0052] like Figure 6 and Figure 7 As shown, the two rotating shafts 75 are provided with threads 751 , and the spiral directions of the two threads 751 are opposite. The rotating shafts 75 are provided with sliding nut seats 61 , and the sliding nut seats 61 cooperate with the threads 751 .

[0053] When the pedal 72 moves downward, the first driving rod 73 will start to rotate and drive the rotating shafts 75 on both sides to rotate synchronously. In order to ensure that the sliding nut seat 61 on the rotating shaft 75 can move in the same direction simultaneously, the threads 751 on the rotating shafts 75 on both sides must be designed to rotate in the opposite direction.

[0054] like Figure 7 As shown, a first ratchet 752 is provided on one end of the rotating shaft 75, and a second ratchet 753 is provided on the other end, and the unidirectional driving directions of the first ratchet 752 and the second ratchet 753 are opposite, and the first ratchet 752 and the second ratchet 753 are respectively connected to the first rotating wheel 732 and the second rotating wheel 742 through a belt 8.

[0055] When the first driving rod 73 rotates, the rotating shaft 75 rotates accordingly, but due to the action of the second ratchet 753, the rotating shaft 75 will not drive the second driving rod 74 to rotate; similarly, when the second driving rod 74 rotates, the action of the first ratchet 752 will prevent the rotating shaft 75 from driving the first driving rod 73 to rotate. In this way, the power can be reasonably distributed to ensure that each component works in coordination, thereby greatly improving the transmission efficiency of the entire system.

[0056] like Figure 8 As shown, a first electromagnet 761 is installed at the bottom of the support column 76 , and a second electromagnet 781 is installed at the bottom of the cylinder 78 .

[0057] The first electromagnet 761 and the second electromagnet 781 can lock the support column 76 and the cylinder 78 with each other by adjusting the magnetic force therebetween, thereby preventing the worker from continuing to press down the pedal 72 after passing through the rear door 6, thereby preventing the rear door 6 from moving again. At the same time, the electromagnet will also lock the pressed pedal 72, thereby preventing the pedal 72 from rising after the worker leaves the pedal 72, thereby preventing the rear door 6 from moving. When all workers leave the air shower room, the first electromagnet 761 and the second electromagnet 781 are powered off, releasing the locking effect, and restoring the pedal 72 and the rear door 6 to their initial positions.

[0058] like Fig. 9 As shown, the rack 79 includes a connecting block 791, a first tooth 792, a first spring 793, a second tooth 794 and a second spring 795. The top of the connecting block 791 is connected to the bottom of the pedal 72. One end of the first spring 793 is installed on the inner side of the connecting block 791. The first tooth 792 is slidably installed on the inner side of the connecting block 791, and the first tooth 792 is connected to the first spring 793. One end of the second spring 795 is installed on the outer side of the connecting block 791. The second tooth 794 is slidably installed on the outer side of the connecting block 791, and the second tooth 794 is connected to the second spring 795. The tooth tips of the first tooth 792 and the second tooth 794 are in opposite directions.

[0059] When the rack 79 moves downward, the first tooth 792 extends and drives the first drive rod 73 to rotate, while the second tooth 794 is compressed into the connection block 791; conversely, when the rack 79 moves upward, the second tooth 794 extends to drive the second drive rod 74 to rotate, while the first tooth 792 is compressed into the connection block 791. During the entire process of the pedal 72 moving up and down, the first tooth 792 and the second tooth 794 automatically return to their initial positions through the elastic force of the first spring 793 and the second spring 795, thereby ensuring the stable operation of the system and the smoothness of function switching.

[0060] The height value of the pedal 72 moving downward is equal to the distance value of the rear door 6 moving backward, and the distance value of the rear door 6 moving backward is equal to the width value of the pedal 72.

[0061] The height of the pedal 72 moving downward is equal to the distance the rear door 6 moves backward, and this design ensures the precise linkage of the system. When the first worker enters the air shower room and steps on the pedal 72, the rear door 6 will move backward a corresponding distance to make room for the next pedal 72 for the worker, while allowing the rear door 6 to move further to ensure that there is space for the second worker to enter. This design not only optimizes space utilization, but also allows for rapid passage of people.

[0062] like Figure 2 and Figure 3 As shown, electric wires 21 are respectively provided on the top of the front door 2 , and beam sensors 9 are installed on both sides of the rear door 6 .

[0063] The wire 21 is used to provide power support for the rear door 6 and the components installed thereon, and the through-beam sensor 9 is used to sense the closing state of the front door 2. When the front door 2 is closed, the through-beam sensor 9 sends a signal to control the air nozzle 3 of the relevant module inside the air shower room to start working, thereby significantly improving the efficiency of the air shower room operation.

[0064] Working process: After the worker opens the front door 2, the first person enters the air shower chamber 1 and steps on the pedal 72. Due to the weight of the human body, the pedal 72 is subjected to downward pressure, and the pedal 72 moves downward, so that the rack 79 at the bottom of the pedal 72 moves downward, and the first tooth 792 inside the rack 79 engages with the first rotating tooth 731 on the first driving rod 73, and drives the first rotating tooth 731 to rotate, so that the first driving rods 73 on both sides rotate, and the first driving rod 73 drives the first rotating wheel 732 to rotate and transmits power to the first ratchet 752 through the belt 8. The rotation of the first ratchet 752 drives the rotating shaft 75 to rotate, and the rotating shaft 7 The second ratchet wheel 753 at the other end will not rotate, and the rotating shafts 75 on both sides rotate simultaneously, which will drive the sliding nut seat 61 on the rotating shaft 75 to move backward at the same time, thereby driving the entire rear door 6 to move a distance of the width of the pedal 72, and the second teeth 794 on the outer side of the rack 79 at the bottom of the pedal 72 will be compressed into the inside of the connecting block 791, and the second spring 795 inside the connecting block will be compressed, and the first electromagnet 761 in the supporting column 76 and the second electromagnet 781 in the cylinder 78 will be energized, so that the magnetic properties of the first electromagnet 761 and the second electromagnet 781 are different, and they are attracted to each other, preventing the pedal 72 from returning to its original position.

[0065] When the second worker enters, the first worker will step on the second pedal 72, causing the second pedal 72 to move downward, thereby causing the rear door 6 to move backward again. If there are more workers entering later, the first person will step on the third pedal 72, the second person will step on the second pedal 72, and the third person will step on the first pedal 72. When no more workers enter, the front door 2 will be closed. At this time, after the through-beam sensor 9 detects that the front door 2 is closed, the air nozzle 3 inside the air shower chamber 1 will work and spray a large amount of air.

[0066] When the front door 2 is closed, the pedal 72 that has not moved downward at the back will be energized with the first electromagnet 761 and the second electromagnet 781 therein and generate the same magnetism, so that the first electromagnet 761 and the second electromagnet 781 repel each other. When the air shower chamber 1 is finished working, the air nozzle 3 will not spray air. The first worker can open the rear door 6 and walk over the pedal 72. At this time, the subsequent pedals 72 will not move downward, and the pedal 72 stepped on by the front door 2 will not move upward to return to its original position. Until the last worker walks out of the air shower chamber 1, the first electromagnet 761 and the second electromagnet 781 inside the stepped pedal 72 will be de-energized, and the elastic potential energy of the compression spring 77 will cause the pedal 72 to move upward. When the pedal 72 moves upward, the second tooth 794 on the bottom rack 79 will mesh with the second rotating tooth 741 and drive the second driving rods 74 on both sides to rotate in the opposite direction, thereby rotating the second rotating wheel 742, and the first tooth 792 on the inner side of the rack 79 will be compressed into the inside of the connecting block 791, and the first compression spring 77 will be compressed; the second rotation transmits power to the second ratchet wheel 753 through the belt 8, and the rotation of the second ratchet wheel 753 will drive the rotating shaft 75 to rotate. At this time, the first ratchet wheel 752 at the other end of the rotating shaft 75 will not rotate, thereby causing the rotating shaft 75 to rotate in the opposite direction and driving the sliding nut seat 61 on the rotating shaft 75 to move in the opposite direction, and the sliding nut seat 61 will drive the rear door 6 to return to its original position.

[0067] Therefore, according to the number of people entering the air shower chamber 1, the distance moved by the rear door 6 is controlled, thereby controlling the operation of each air nozzle 3 in the entire air shower chamber 1, which greatly saves energy consumption and improves the efficiency of air shower operation.

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
