[0030] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0031] Example 1:

[0032] like Figure 1 As shown in FIG10 , the utility model provides an ice purifier, which includes an ice crushing mechanism 100 and an ice making refrigerator 200 connected to the ice crushing mechanism 100. The ice making refrigerator 200 is installed on the upper side of the ice crushing mechanism 100. An ice storage chamber 210 capable of accommodating ice cubes is provided in the ice making refrigerator 200. An ice delivery channel connected to the ice storage chamber 210 is provided between the ice making refrigerator 200 and the ice crushing mechanism 100. Usually, the ice purifier also includes an ice making assembly 300 provided in the ice making refrigerator 200. The ice cubes made by the ice making assembly 300 fall into the ice storage chamber 210 and are transported to the ice crushing mechanism 100 through the ice delivery channel for crushing.

[0033] like Figure 1As shown in FIG3 , the ice crushing mechanism 100 includes an ice crushing assembly 110, a driving device 120 provided on one side of the ice crushing assembly 110, and a waterproof connector 130 provided between the ice crushing assembly 110 and the driving device 120. In this embodiment, the ice crushing assembly 110 is used for crushing ice. The ice crushing assembly 110 is installed at the lower part of the refrigerator 200. The ice delivery channel is provided between the refrigerator 200 and the ice crushing assembly 110. The ice cubes in the ice storage chamber 210 are transported to the ice crushing assembly 110 for crushing ice through the ice delivery channel. The driving device 120 is installed below the ice crushing assembly 110 through the waterproof connector 130. The driving device 120 is used to drive the ice crushing assembly 110 to crush ice. The waterproof connector 130 includes a water retaining portion 131 that can cover the upper side of the driving device 120. The waterproof connector 130 can be rotated by the driving device 120 and drive the water retaining portion 131 to rotate synchronously. Since the driving device 120 is installed below the ice crushing assembly 110, ice cubes in the ice crushing assembly 110 will form melted water after melting, and the melted water will easily fall into the driving device 120 along the assembly gap 1112 in the ice crushing assembly 110. In order to prevent the driving device 120 from being damaged by the erosion of the melted water, the waterproof connector 130 is provided between the ice crushing assembly 110 and the driving device 120. The water retaining portion 131 on the waterproof connector 130 covers the upper side of the driving device 120 to isolate the ice crushing assembly 110 and the driving device 120, so that the melted water falls on the water retaining portion 131, thereby preventing the melted water from falling into the driving device 120. When the ice crushing mechanism 100 is in operation, the waterproof connector 130 is driven to rotate by the driving device 120, and the ice crushing assembly 110 is driven to crush ice by the waterproof connector 130. During this process, the waterproof connector 130 is rotated by the driving device 120 and drives the water retaining portion 131 to rotate synchronously, so that when the melted ice water falls on the water retaining portion 131, it can be thrown out of the ice crushing mechanism 100 by the rotating water retaining portion 131, or the water stains on the water retaining portion 131 can be thrown out of the ice crushing mechanism 100 by the centrifugal force generated by the rotating water retaining portion 131, thereby achieving the purpose of protecting the driving device 120, extending the service life of the driving device 120, and reducing safety hazards.

[0034] Specifically, such as Figure 1As shown in FIG3 , the driving device 120 includes a driving motor 121 and an output shaft 122 connected to the driving motor 121. The water retaining portion 131 can cover the connection between the output shaft 122 and the driving motor 121. The waterproof connector 130 also includes a first mounting portion 132 that can be connected to the driving device 120. The first mounting portion 132 is provided on one side of the water retaining portion 131. The waterproof connector 130 is connected to the output shaft 122 through the first mounting portion 132. The output shaft 122 is driven to rotate by the driving motor 121, and the output shaft 122 drives the waterproof connector 130 to rotate. In this embodiment, when the waterproof connector 130 is installed on the output shaft 122 through the first mounting portion 132, the water retaining portion 131 can cover the connection between the output shaft 122 and the drive motor 121, that is, the projected area of ​​the water retaining portion 131 is larger than the radial cross-sectional area of ​​the connection between the output shaft 122 and the drive motor 121. Preferably, the projected area of ​​the water retaining portion 131 is greater than or equal to the radial cross-sectional area of ​​the drive motor 121, so that the melted ice water falls onto the water retaining portion 131 instead of falling into the drive motor 121, thereby protecting the drive device 120, extending the service life of the drive device 120, and reducing safety hazards. In addition, the first mounting portion 132 and the output shaft 122 can be detachably connected by means of plug-in, snap-on, threaded connection, etc. Preferably, the first mounting portion 132 can be configured as a first mounting hole provided on the lower side of the water retaining portion 131 and open downward, and the first mounting hole is adapted to the output shaft 122, wherein the cross-section of the first mounting hole can be rectangular, circular, D-shaped, etc.; during installation, the waterproof connector 130 can be directly plugged into the output shaft 122 through the first mounting hole, and the first mounting portion 132 has a simple structure, making the waterproof connector 130 easy to disassemble and assemble.

[0035] As a preferred embodiment of the present invention but not limited to the following, Figure 5As shown in FIG. 7 , the waterproof connector 130 further includes a cylindrical portion 133 disposed on the outside of the first mounting portion 132 and a shoulder portion 134 disposed on the periphery of the cylindrical portion 133 .

The top surface of the barrel 133 and the top surface of the shoulder 134 form the water retaining portion 131. Since the side wall of the barrel 133 may also come into contact with melted ice water, the side wall of the barrel 133 is also part of the water retaining portion 131.

[0036] As a preferred embodiment of the present invention but not limited to the following, Figure 5 As shown in FIG. 7 , the waterproof connector 130 further includes a first reinforcing rib 1351 provided between the barrel 133 and the shoulder 134, and at least a portion of the water retaining portion 131 is provided on the outer wall surface of the first reinforcing rib 1351; a plurality of first reinforcing ribs 1351 are provided, and each of the first reinforcing ribs 1351 is arranged along the circumference of the shoulder 134. Preferably, each of the first reinforcing ribs 1351 is evenly arranged along the circumference of the shoulder 134. In this embodiment, the first reinforcing ribs 1351 are connected between the side wall of the cylinder 133 and the top surface of the shoulder 134. When installed, each of the first reinforcing ribs 1351 is located below the ice crushing assembly 110 and opposite to the ice crushing assembly 110. The outer wall surface of each of the first reinforcing ribs 1351 can contact the melted ice water. Therefore, the outer wall surface of each of the first reinforcing ribs 1351 is also part of the water retaining portion 131. When the ice crushing mechanism 100 is in a humid environment, the waterproof connector 130 is rotated by the driving device 120 and drives each of the first reinforcing ribs 1351 to move. The first reinforcing ribs 1351 rotate, and the contact area between the water retaining part 131 and the melted ice water is increased through each of the first reinforcing ribs 1351, and the air flow in the waterproof connector 130 is enhanced, thereby improving the surface drying speed of the water retaining part 131, which is beneficial to accelerate the evaporation of the melted ice water on the surface of the water retaining part 131; in addition, by arranging a plurality of the first reinforcing ribs 1351 between the barrel 133 and the shoulder 134, it is beneficial to enhance the structural strength of the waterproof connector 130 and extend the service life of the waterproof connector 130.

In this embodiment, the barrel portion 133 defines a downwardly open inner cavity 1331. The extension portion 136 is disposed within the inner cavity 1331 and connected to the barrel portion 133. The extension portion 136 extends downwardly along the height of the inner cavity 1331. The first mounting portion 132 is disposed within the extension portion 136. To further enhance the structural strength of the waterproof connector 130, a second reinforcing rib 1352 is connected to the extension portion 136. Optionally, the second reinforcing rib 1352 may be disposed between the inner wall of the barrel portion 133 and the extension portion 136; or between the bottom of the shoulder portion 134 and the extension portion 136; or, as shown in the figure, the second reinforcing rib 1352 may be disposed between both the inner wall of the barrel portion 133 and the bottom of the shoulder portion 134, and the extension portion 136. Preferably, a plurality of second reinforcing ribs 1352 are provided and evenly distributed along the circumference of the outer wall of the extension portion 136.

[0038] In some other embodiments, the first mounting portion 132 is configured as a first mounting hole located in the extending portion 136 and open downward, and the first mounting hole is connected to the output shaft 122 .

[0039] As a preferred embodiment of the present invention but not limited to the following, Figure 5 As shown in FIG. 7 , the waterproof connector 130 further includes a rim portion 137 disposed on the outer edge of the shoulder portion 134. The rim portion 137 has a curved outer wall 1371. In this embodiment, the outer edge of the shoulder portion 134 extends downward to form the rim portion 137, and the outer wall surface of the rim portion 137 is configured as a curved surface. The provision of the rim portion 137 with the curved outer wall 1371 in the waterproof connector 130 helps prevent scratches on production workers during assembly of the waterproof connector 130, reduces safety hazards during the production and assembly of the waterproof connector 130, and thereby improves the production and assembly efficiency of the waterproof connector 130.

[0040] In other embodiments, the second reinforcing rib 1352 disposed between the extension portion 136 and the shoulder portion 134 may be connected to the edging portion 137 to further enhance the structural strength of the waterproof connector 130 .

[0041] Example 2:

[0042] This embodiment 2 can be improved on the basis of the above embodiment 1, such as Figure 8 As shown in FIG. 10 , the ice crushing assembly 110 includes a main bracket 111 provided on one side of the waterproof connector 130, and a clearance cavity 1111 communicating with the outside is provided in the main bracket 111, and at least a portion of the waterproof connector 130 can extend into the clearance cavity 1111, and the portion of the waterproof connector 130 extending into the clearance cavity 1111 is opposite to the inner wall of the clearance cavity 1111 and forms a gap 1112. In this embodiment, the main bracket 111 is installed at the lower part of the ice making refrigerator 200, and the bottom of the main bracket 111 is provided with the give way cavity 1111. During installation, at least a portion of the waterproof connector 130 can extend from bottom to top into the give way cavity 1111, and the extended portion of the waterproof connector 130 is opposite to the inner wall of the give way cavity 1111 and forms a gap 1112.
