[0027] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, an efficient dust-proof air shower system includes a controller 1, which is respectively connected to a first electronic lock 2, a second electronic lock 3, a light sensor 4, an air extraction channel 5 and an air outlet channel 6, wherein the first electronic lock 2 is arranged at the front door of the air shower, and the second electronic lock 3 is arranged at the rear door of the air shower. The controller 1 is connected to an acoustic alarm or a light alarm arranged on the front door and / or the rear door.

[0029] like Figure 2-3As shown, the exhaust channel 5 is provided with an exhaust fan 7 and an exhaust electric control door 8. The exhaust fan 7 is used to suck the gas in the air shower room into the air shower system. The exhaust channel 5 is provided with a primary filter 9 at the air inlet, and a high-efficiency filter 10 and an air shower nozzle 11 at the air outlet; the outlet channel 6 is provided with an outlet fan 12 and an exhaust electric control door 13. The outlet fan 12 is used to suck the gas outside the air shower room and blow it into the air shower room. In order to ensure the cleanliness of the intake air, a primary filter 9 is provided at the air inlet of the outlet channel 6. Since it is provided outside the air shower room, it will not cause pollution to the air shower room when it is replaced. Based on the above structure, this technology has the following control logic:

[0030] When the front door of the air shower room is opened, that is, the first electronic lock 2 is opened, it is easy to bring external polluted air into the air shower room, which increases the degree of air pollution in the air shower room, thereby shortening the service life of the filter. Therefore, after the controller 1 receives the door opening signal of the first electronic lock 2, it opens the air outlet electric control door 13 and the air outlet fan 12 front and back to form a positive pressure in the air shower room, blow the air in the air shower room out from the front door, and prevent the outside air from entering the air shower room from the front door, ensuring the air in the air shower room is close, and at the same time, the people or objects entering are initially air showered; when the front door of the air shower room is closed, that is, the first electronic lock 2 is closed, the air outlet fan 12 and the air outlet electric control door 13 are closed successively. This technology transfers part of the filtering work that should be done by the internal filter of the air shower room to the external filtering, which is convenient for the replacement of the primary filter 9, and avoids the problem of secondary pollution in the air shower room caused by the replacement of the primary filter 9.

[0031] When the optical sensor 4 detects the blocking signal, it means that there is an object or person in the air shower room at this time, then the optical sensor 4 sends the blocking signal to the controller 1, and the controller 1 detects the state of the first electronic lock 2 and the second electronic lock 3. If the first electronic lock 2 and the second electronic lock 3 are both in the closed state, that is, the closed signal of the first electronic lock 2 and the second electronic lock 3 is collected, then the exhaust electric control door 8 and the exhaust fan 7 are controlled to open, and the airflow entering the exhaust channel 5 passes through the primary filter 9, the high-efficiency filter 10 and the air shower nozzle 11 in sequence, and the clean gas is blown to the person or object. Three air shower modes of single-side blowing, double-side blowing and three-side blowing can be set, and the waiting time, air shower duration, wind speed, air volume and other parameters can also be adjusted. These parameters are initially set by the factory, and then the user can adjust them by himself, such as adjusting the time relay to change the air shower duration. Since the dust blown off from people or objects and the dust in the air shower room will fall, the air intake of the exhaust air duct is set at the bottom of the air shower room, and the primary filter 9 is set at the air intake.

[0032] In order to save equipment space, the present technology preferably uses the same air inlet for the air intake channel 5 and the air outlet channel 6, and the air intake channel and the air outlet channel can be separated by a partition. A linkage electric control door is provided at the diversion point between the air intake channel 5 and the air outlet channel 6, such as Figure 4-6 As shown, the linked electric-controlled door includes an L-shaped door 14 and a drive motor 18. The drive motor 18 controls the rotation of the L-shaped door 14. The L-shaped door 14 is arranged between the air outlet channel 6 and the exhaust channel 5, that is, the L-shaped door 14 is connected to the partition. There is no contact between the L-shaped door 14 and the partition to avoid the partition increasing the friction of the L-shaped door 14 when rotating. Rotating the L-shaped door 14 will inevitably close one of the air ducts and open the other air duct, so that only one motor is needed to realize the simultaneous control of the opening and closing of the two air ducts.

[0033] In order to increase the rotation accuracy of the L-shaped door 14, a limit bracket 15 for limiting the rotation position of the L-shaped door 14 is provided in the exhaust channel 5 and the outlet channel 6. The limit bracket 15 is set at the closed position of the L-shaped door 14 when the air duct is closed. In order to increase the fit between the L-shaped door 14 and the limit bracket 15, a step structure that fits with the limit bracket 15 can be added to the outer edge of the L-shaped door 14, so that a chimera is formed between the L-shaped door 14 and the limit bracket 15, which can increase the blocking effect of the L-shaped door 14. In order to increase the blocking effect of the L-shaped door 14, an electromagnet 16 is provided on the limit bracket 15, and the electromagnet 16 is connected to the controller 1. When the L-shaped door 14 is closed to one side, the controller 1 controls the electromagnet 16 on that side to start, and the magnetic force generated by the electromagnet 16 sucks the L-shaped door 14, thereby increasing the wind resistance of the L-shaped door 14.

[0034] The L-shaped door 14 is provided with an air inlet groove 17, the depth of which gradually deepens from the outer edge of the door panel of the L-shaped door 14 to the inner edge of the door panel, and can guide the wind blowing onto the L-shaped door 14 to open the air duct, thereby increasing the wind resistance of the L-shaped door 14.

[0035] In order to avoid ending the air shower before the residual impurities in the air shower room are removed, an air quality sensor can be installed in the air shower room to monitor the concentration of pollutants in the air in the air shower room. When the air quality in the air shower room increases above the threshold and does not change direction for a certain period of time, such as 5 seconds, the air shower is stopped.

[0036] The air shower room control system in the present technology is not the front and rear door interlocking in the traditional sense. Since fire, earthquake, explosion and other accidents may occur in daily work, if the front and rear door interlocking is used, the rear door cannot be opened when the front door is opened. Therefore, the present technology sets an emergency switch outside the rear door. If the emergency switch is pressed, the sound and light alarm will start to alarm, and the controller 1 will control the first electronic lock 2 and the second electronic lock 3 to open, so that the staff in the clean room can directly and quickly pass through the air shower room, avoiding the problem of missing the escape opportunity due to the obstruction of the air shower room.

[0037] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
