[0018] The following further describes the technical solution of the present utility model in detail with reference to the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3, the present utility model provides a technical solution: an automatic air curtain door for a cold storage, which includes a door frame 1. Inside the door frame 1, there is a movable door 2. On one outer wall of the door frame 1, an air pump 3 is fixedly connected. At the outlet of the air pump 3, an air delivery pipe 5 is fixedly connected. At the bottom of the air delivery pipe 5, a sealing block 6 is fixedly connected. Inside the wall of the air delivery pipe 5, a support shaft 7 is movably connected. On the outer wall of the support shaft 7, a movable pipe 8 is fixedly connected. At the bottom of the movable pipe 8, a nozzle 9 is fixedly connected. On the other outer wall of the door frame 1, a driving motor 4 is fixedly connected. The output shaft of the driving motor 4 is fixedly connected to a lead screw 13 through a coupling. On the outer wall of the lead screw 13, a movable block 12 is movably connected. By providing the door frame 1, the movable door 2, the air pump 3, the driving motor 4, the air delivery pipe 5, the sealing block 6, the support shaft 7, the movable pipe 8, the nozzle 9, the air intake groove 10, the air outlet 11, the movable block 12, and the lead screw 13, it is convenient to drive the nozzle 9 to swing, thereby increasing the jet range. Further, it is beneficial to reduce the arrangement quantity of the nozzles 9, thus reducing the manufacturing cost and meeting the working requirements of people, and it is worthy of popularization and use.

[0020] Furthermore, the sealing blocks 6 are distributed in an elliptical shape, and the sealing blocks 6 are made of elastic rubber material, which facilitates the sealing work.

[0021] Furthermore, the movable pipe 8 is rotatably connected to the air delivery pipe 5 through the support shaft 7, and the movable pipe 8 penetrates through the bottom wall of the air delivery pipe 5 through the sealing block 6, which facilitates the support of the movable pipe 8.

[0022] Furthermore, an air intake groove 10 is provided at the top of the movable pipe 8, and the air intake grooves 10 are symmetrically distributed on both sides of the movable pipe 8, which facilitates the airflow to enter the inside of the movable pipe 8.

[0023] Furthermore, air outlets 11 are provided at the bottom of the nozzles 9, and the air outlets 11 are evenly distributed, which facilitates uniform jetting.

[0024] Furthermore, the movable block 12 is threadedly connected to the lead screw 13, the lead screw 13 is a reciprocating lead screw, and the movable block 12 is connected to the top of the movable pipe 8, which facilitates driving the movable block 12 to slide reciprocally.

[0025] During use, first start the air pump 3 and the driving motor 4, so that the air pump 3 drives the airflow to enter the inside of the air delivery pipe 5, and the airflow enters the inside of the movable pipe 8 through the air intake groove 10. Then, after being discharged through the air outlets 11 at the bottom of the nozzles 9, the jetting work is realized. At the same time, the driving motor 4 drives the lead screw 13 to rotate. Through the reciprocating lead screw arrangement of the lead screw 13, the lead screw 13 drives the movable block 12 to slide reciprocally, so that the movable block 12 drives the movable pipe 8 to rotate reciprocally under the support of the support shaft 7. Then, the support shaft 7 drives the nozzle 9 to swing, which is beneficial to increasing the jet range and solves the problem that the narrow jet range leads to an increase in the arrangement quantity of the nozzles 9.
