The snow ice machine can freeze fresh milk liquid and fresh fruit juice extremely fast, so that the fresh milk liquid and fresh fruit juice are frozen into ice crystals at -27°C to -35°C within 5 to 8 seconds, while making ice-cold snow ice food without losing the original nutrition and delicious taste. The snow ice machine usually includes structures such as a refrigeration unit and a snow-making unit. Among them, the snow-making unit generally includes a liquid supply device, an evaporator cylinder, a snow-making knife assembly, a driving motor and other structures. The evaporator cylinder is driven to rotate by the driving motor, and the snow-making knife assembly is arranged on the lower side of the evaporator cylinder for shoveling the snow ice frozen on the surface of the evaporator cylinder. The liquid supply device includes a liquid material bottle and a liquid material box. The liquid material in the liquid material bottle flows into the liquid material box, and the evaporator cylinder continuously rotates to pick up the liquid material from the liquid material box and freezes it into ice.

[0003] At normal temperature, if milk liquid and fruit juice are exposed to the atmospheric environment for a long time, microorganisms will multiply quickly, and the residual liquid will quickly deteriorate and produce peculiar smell. Therefore, the residual ice and residual liquid after snow ice making must be cleaned in time.

On one side of the beverage tray 3, there is an overflow port 301 for the waste water to overflow; during cleaning, the cleaning water pump 5 extracts the clean water in the cleaning water box 4 and sprays it on the evaporator drum 2 through the spray pipe 6 to clean it. During the cleaning process, the evaporator drum 2 rotates, the cleaning is more uniform, and the cleaning effect is better; the waste water after cleaning flows into the beverage tray 3 and flows out through the overflow port 301.

[0047] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 4 , the self-cleaning component further includes a water collection box 7 installed on the lower side of the front end of the housing 1. The water collection box 7 is used to place the snow ice container during ice making on the one hand, and to receive the waste water after cleaning on the other hand. The water collection box 7 corresponds to the position of the overflow port 301 to receive the waste water flowing out from the overflow port 301. With this structure, setting the water collection box 7 can receive and collect the cleaning waste water, which is convenient for cleaning.

[0048] In some embodiments, as Figure 4 and Figure 5 shown, a rear end of the housing 1 is recessed to form a water tank groove 103 for placing the cleaning water tank 4, and the cleaning water tank 4 is detachably installed in the water tank groove 103. A check valve 41 is provided at the bottom of the cleaning water tank 4. When the cleaning water tank 4 is detached from the water tank groove 103, the check valve 41 automatically closes to prevent water from flowing out during water filling, avoiding water stains, facilitating water filling, and having a good use effect. A push rod 81 corresponding to the check valve 41 is provided at the bottom of the water tank groove 103; when the cleaning water tank 4 is placed in the water tank groove 103, the push rod 81 pushes open the check valve 41, so that the cleaning water tank 4 is communicated with the cleaning water pump 5.

When the cleaning water tank 4 is detached from the water tank groove 103, under the action of the top head spring 413, the top head seal ring 412 closes the water outlet to prevent water from flowing out, ensuring the feasibility of the structure and improving the convenience of water filling.

[0050] In some embodiments, as Figure 4 、 Figure 6 and Figure 7 shown, the cleaning water tank 4 includes a water tank body 42 and a water tank cover 43 sleeved at the end of the water tank body 42. A hook 421 is provided on the back of the water tank body 42, and a hook groove 104 adapted to the hook 421 is provided in the water tank groove 103; the cleaning water tank 4 is detachably installed in a hooking manner, which is convenient for disassembly and assembly and water filling. A cleaning pipe joint 8 is fixed at the bottom of the water tank groove 103, the push rod 81 is arranged in the cleaning pipe joint 8, and the cleaning pipe joint 8 is communicated with the cleaning water pump 5 through a pipeline.

[0051] In some embodiments, as Figure 3 、 Figure 10 and Figure 12As shown in the figure, a U-shaped water baffle 302 is provided on the outer wall of the beverage tray 3 around the water overflow port 301. The U-shaped water baffle 302 is used to prevent the waste water from flowing along the outer wall of the beverage tray 3 onto the housing 1. Among them, the U-shaped water baffle 302 and the beverage tray 3 are of an integral structure. The U-shaped water baffle 302 can block water, enabling the waste water flowing out of the water overflow port 301 to smoothly enter the water collection box 7, and avoiding the waste water flowing along the outer wall of the beverage tray 3 onto the housing 1, causing water stains.

[0052] In some embodiments, as Figures 9 to 11 shown, an ice-making inner shell 9 for enclosing an ice-making cavity 101 is provided inside the housing 1. The evaporator drum 2 is rotatably installed on the ice-making inner shell 9, and a driving motor for driving the evaporator drum 2 is installed on the ice-making inner shell 9.

The arrangement of the water leakage holes 731 facilitates the waste water from cleaning to enter the water collection box body 72. The float 71 can rise under the buoyancy of water. A perforation for the float 71 to rise is provided on the water collection box cover 73. The float 71 can remind the user that the waste water is full, so as to facilitate the user to clean the waste water in the water collection box 7 in time.

[0054] In some embodiments, as Figure 3 、 Figure 9 and Figure 10 shown, a cutting knife 12 is installed along the tangential direction of the outer wall of the evaporator drum 2 in the ice-making cavity 101. A snow guiding trough 13 is installed on one side of the cutting knife 12, and the position of the snow guiding trough 13 corresponds to that of the water collection box 7. During cleaning, as the evaporator drum 2 rotates, the cutting knife 12 scrapes off the dirt and part of the waste water on the outer wall of the evaporator drum 2, and the waste water flows into the water collection box 7 through the snow guiding trough 13.

[0055] In some embodiments, as Figure 4 and Figure 8 shown, a compressor 14, a condenser 15 and a cooling fan 16 are installed in the installation cavity 102, and a beverage bottle body 17 for putting beverages into the beverage tray 3 is provided at the upper end of the housing 1.
