[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, this utility model provides a technical solution:

[0025] A dry ice basket lifting device for a dry ice machine includes a water tank 1. A lifting frame 2 is movably arranged at the lower part of the interior of the water tank 1. A basket frame 3 is movably arranged at the upper end of the lifting frame 2. A lifting mechanism is arranged below the basket frame 3. The lifting mechanism includes a sleeve 7. Sleeves 7 are arranged at the lower part of the four sides of the interior of the water tank 1. A piston rod 8 is movably arranged inside the sleeve 7. The top end of the piston rod 8 is fixedly connected to the lifting frame 2. A diverter pipe 9 is connected to the top of the air pump 4. The other end of the diverter pipe 9 is connected to the lower part of the bottom end of the sleeve 7. A rubber corrugated pipe 10 is arranged between the lifting frame 2 and the sleeve 7 and outside the piston rod 8. A sliding groove 11 is arranged on the inner wall of the water tank 1 and on both sides of the wall groove 5. Pulleys 12 matching the sliding groove 11 are arranged at the upper and lower ends of both sides of the basket frame 3. Support feet 16 are arranged at the four corners of the bottom end of the water tank 1.

[0026] In this embodiment, the air pump 4, the diverter pipe 9, the sleeve 7 and the piston rod 8 are used in combination to drive the piston rod 8 with compressed air, thereby realizing the automatic lifting and lowering of the basket 3. The operation is convenient and labor-saving, and the position and movement speed of the dry ice basket can be precisely controlled. At the same time, the rubber corrugated pipe 10 plays a protective role for the piston rod 8, reducing the probability of failure and lowering maintenance costs.

[0027] like Figure 3 As shown, an air pump 4 is installed at the bottom center of the water tank 1. Wall grooves 5 are installed on the lower part of the inner walls on both sides of the water tank 1. A perforated nozzle 6 is installed vertically inside the wall groove 5. A spraying mechanism is installed between the air pump 4 and the perforated nozzle 6. The spraying mechanism includes a reversing valve 13. The reversing valve 13 is installed at the end of the air pump 4 away from the diversion pipe 9. An air inlet and outlet pipe 14 and an air supply pipe 15 are respectively installed at the other two ends of the reversing valve 13. The end of the air supply pipe 15 away from the reversing valve 13 passes through the water tank 1 and is connected to the perforated nozzle 6.

[0028] In this embodiment, the airflow direction is controlled by the reversing valve 13, which causes compressed air to be ejected from the perforated nozzle 6, promoting the flow of water in the water tank 1, accelerating the sublimation rate of dry ice, making the smoke generation more rapid, and enabling the smoke distribution to be more uniform, greatly improving the overall smoke effect and meeting the diverse needs for smoke effects in different scenarios.

[0029] Working principle: When the basketball hoop 3 needs to be raised, the air pump 4 starts, and the compressed air it generates is delivered to the bottom of the sleeve 7 on all four sides inside the water tank 1 via the distributor pipe 9. Since the piston rod 8 is movable inside the sleeve 7 and its top end is fixed to the lifting frame 2, the compressed air pushes the piston rod 8 upward within the sleeve 7, thereby driving the lifting frame 2 to rise and lifting the basketball hoop 3 located at the top of the lifting frame 2. During this process, the rubber corrugated pipe 10 protects the piston rod 8 from the influence of the water in the water tank 1. Meanwhile, the pulleys 12 at the top and bottom of both sides of the basketball hoop 3 roll along the sliding grooves 11 on the inner wall of the water tank 1, ensuring that the basketball hoop 3 rises smoothly. When the basketball hoop 3 needs to be lowered, the air pump 4 stops delivering compressed air to the sleeve 7, and the piston rod 8 descends within the sleeve 7 under its own weight and the weight of the basketball hoop 3, driving the basketball hoop 3 down. In addition, the compressed air generated by the air pump 4 can also function through the spraying mechanism. The reversing valve 13 controls the airflow direction. When spraying is needed, the reversing valve 13 is operated to switch the compressed air from the intake and exhaust pipe 14 to the air supply pipe 15, and then into the perforated nozzle 6. The compressed air is sprayed out from the small holes of the perforated nozzle 6, which can promote the flow of water in the water tank 1 to accelerate the sublimation of dry ice, enhance the smoke effect, or clean the inside of the water tank 1. When spraying is not needed, the reversing valve 13 is operated to allow the compressed air to flow back to the diversion pipe 9 to control the raising and lowering of the basket 3. The four support feet 16 at the bottom corners of the water tank 1 serve to support the device and ensure its working stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
