When the evaporator 2 rotates, the oil return guiding groove 9 of the support sleeve rotates accordingly, and can guide the cooling oil in the evaporator 2 to the oil return guiding section 91 through the grasping section 92 and finally into the oil return hole 61. The grasping section 92 has a guiding arc surface.

[0043] In other embodiments, the drive belt 73 and the pulley can be replaced with a gear drive mechanism, a chain drive mechanism, or a worm and worm wheel mechanism. In addition, the power source of the rotary drive mechanism 7 can be replaced with a hydraulic drive mechanism or a pneumatic drive mechanism.

[0044] Combined Figure 8 As shown, a compressor 10 and a condenser 101 are further provided in the housing 1. The first refrigerant pipe 5, the evaporator 2, the second refrigerant pipe 6, the compressor 10, and the condenser 101 are connected in sequence. Among them, the first refrigerant pipe 5 connects the condenser 101 and the evaporator 2. The refrigerant flowing out of the condenser 101 enters the evaporator 2 through the first refrigerant pipe 5. The second refrigerant pipe 6 connects the evaporator 2 and the compressor 10. Part of the refrigerant evaporates and absorbs heat in the evaporator 2. The gaseous refrigerant and the remaining liquid refrigerant are sent into the compressor 10 through the second refrigerant pipe 6, and after being pressurized by the compressor 10, they are sent into the condenser 101 for the next heat transfer. A compressor 10 is further provided in the housing 1. The compressor 10 is connected to the first refrigerant pipe 5 and the second refrigerant pipe 6.

[0045] It should be noted that when the water storage tank 15 is working normally, water is discharged from the water outlet 151 to the water passing cavity 12. As the water level at the bottom of the water passing cavity 12 rises, when the water submerges the water outlet 151, the water storage tank 15 stops discharging water, and the water level height in the water passing cavity 12 can be maintained. When the water level in the water passing cavity 12 is too high, the excess water can flow out from the overflow port 121, ensuring the water level height in the water passing cavity 12 from another aspect, ensuring the water level height in contact with the evaporator 2 in the water passing cavity 12, and ensuring that the evaporator 2 can continuously and stably make ice.
