The ice shaving blade is cylindrical, with three cutting teeth on each of the left and right sides of the cylindrical blade body. However, the ice shaving device involved in this patent has certain drawbacks. Due to the bushing between the shaft and the bracket, the shaft's stability during rotation is poor, making it prone to movement and wobbling, which adversely affects the smooth operation of the ice shaving process.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] This invention addresses the aforementioned problems in the prior art by proposing an ice shaver with a double-shaft sleeve, which reduces wear and instability caused by uneven force, improves the stability of the rotating shaft, and enhances the quality and efficiency of ice shaving.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0007] Compared with the prior art, the advantages and positive effects of this utility model are:

[0008] An ice shaver with a double-shaft sleeve, comprising:

[0009] The housing has mounting holes;

[0010] A rotating shaft, which is rotatably mounted in the mounting hole;

[0011] A first bushing and a second bushing are provided axially spaced within the mounting hole.

The radial dimension of the first shaft portion is greater than the radial dimension of the second shaft portion.

[0012] In some embodiments of this application, an ice pressing plate connected to the first shaft portion is also included, and the mounting hole has a main mounting hole that matches the first bushing and an end mounting hole that matches the second bushing.

[0013] In some embodiments of this application, the first bushing has a first bushing portion located inside the main mounting hole and a first extension edge extending radially outward along one end of the first bushing portion near the ice pressing plate, and a first receiving groove matching the first extension edge is provided at the end of the main mounting hole.

[0014] In some embodiments of this application, the second bushing has a second bushing portion located inside the end mounting hole, and a second extension portion extending outward along one end of the second bushing portion near the main mounting hole, the second extension portion being located between the main mounting hole and the end mounting hole.

[0015] In some embodiments of this application, a spring is also included, which is sleeved on the outside of the second shaft portion, with one end of the spring abutting against the first shaft portion and the other end abutting against the second extension portion.

[0016] In some embodiments of this application, the second extension has a second extension edge extending radially outward along the second bushing portion and a second axial edge extending axially toward the main mounting hole along the outer end of the second extension edge, the second extension edge and the second axial edge forming a receiving groove that matches the other end of the spring.

[0017] In some embodiments of this application, the second extension has a second outer extension edge that extends radially outward along the end along the second axial direction, the outer diameter of the second outer extension edge being larger than the radial dimension of the main mounting hole.

[0018] In some embodiments of this application, the radial dimension of the first shaft portion is greater than the inner diameter dimension of the second axial side.

[0044] See Figures 1-10 This is one embodiment of an ice shaver with double bushings proposed in this utility model. The ice shaver 100 with double bushings includes: a housing 10 and a rotating shaft 21. The housing 10 has a communicating mounting hole 11, and the rotating shaft 21 is rotatably mounted in the mounting hole 11. A first bushing 13 and a second bushing 14 are axially spaced within the mounting hole 11. The rotating shaft 21 has a second shaft portion 215 that matches the second bushing 14, and a first shaft portion 216 that is connected to the second shaft portion 215 and matches the first bushing 13. The radial dimension of the first shaft portion 216 is larger than the radial dimension of the second shaft portion 215.

[0045] In this embodiment, a first bushing 13 and a second bushing 14 are axially spaced within the mounting hole 11. The two bushings work together to support and position the rotating shaft 21, effectively limiting its radial movement and swaying during rotation, thus significantly improving its stability. This enhanced stability allows the ice shaving blade to operate more smoothly, reducing problems such as uneven ice thickness and low shaving efficiency caused by shaft wobbling. The radial dimension of the first shaft portion 216 is larger than that of the second shaft portion 215. The different sized shaft portions, when fitted with corresponding bushings, better withstand the various forces generated during ice shaving, reducing wear and instability caused by uneven force distribution.

[0046] In some embodiments of this application, the ice shaver 100 further includes an ice pressing plate 22 connected to the first shaft portion 216. The mounting hole 11 has a main mounting hole 111 that matches the first bushing 13, and an end mounting hole 112 that matches the second bushing 14. The connection between the ice pressing plate 22 and the first shaft portion 216 increases the overall stability of the rotating shaft 11 during operation. During the ice shaving process, the ice pressing plate 22 can apply a certain pressure to the ice block placed at the shaving position, allowing the ice block to fit more tightly against the ice shaver blade. The ice pressing plate 22 is detachably connected to the first shaft portion 216, facilitating cleaning of the ice pressing plate 22. The mounting hole 11 has a main mounting hole 111 and an end mounting hole 112, allowing the bushing to be accurately installed within the mounting hole 11, ensuring the accuracy of the bushing's installation position; this also ensures that the rotating shaft 21 maintains good concentricity after installation, avoiding problems such as shaft shaking and jamming caused by installation errors.

[0047] In some embodiments of this application, the housing 10 has a main housing 15 and an end housing 16 for assembly. The mounting hole 11 has a main mounting hole 111 formed on the main housing 15 and an end mounting hole 112 formed on the end housing 16. Designing the housing 10 as a combination of the main housing 15 and the end housing 16 makes the shape and structure of each part relatively simple, facilitating manufacturing and processing. Components related to the main mounting hole 111 can be installed on the main housing 15 first, and then the end housing 16 can be assembled, gradually completing the assembly of the entire device.

[0048] In some embodiments of this application, the first bushing 13 has a first bushing portion 131 located inside the main mounting hole 111, and a first extension edge 132 extending radially outward along one end of the first bushing 131 near the ice pressing plate 22. A first receiving groove 113 matching the first extension edge 132 is provided at the end of the main mounting hole 111. The radial outward extension of the first extension edge 132, matching the first receiving groove 113 at the end of the main mounting hole 111, provides precise positioning for the first bushing 13, ensuring that the first bushing 13 does not undergo axial displacement within the mounting hole 111; this allows the rotating shaft 21 to maintain good concentricity after installation, thereby ensuring stable fit between the various components of the shaved ice machine. The fit between the first extension edge 132 and the first receiving groove 113 increases the contact area between the first bushing 13 and the main mounting hole 111, making the connection between them more robust. During the operation of the ice shaver, the rotating shaft 21 is subjected to various forces. Through this structural design, these forces can be better transferred to the housing 10, dispersing the local stress, improving the load-bearing capacity and deformation resistance of the entire structure, and enhancing the structural strength and durability of the ice shaver.

[0049] In some embodiments of this application, the second bushing 14 has a second bushing portion 141 located inside the end mounting hole 112, and a second extension portion 142 extending outward along one end of the second bushing portion 141 near the main mounting hole 111, with the second extension portion 142 located between the main mounting hole 111 and the end mounting hole 112. The second bushing portion 142, located inside the end mounting hole 112, provides support and positioning for the rotating shaft 21, ensuring the stability of the rotating shaft 21 at that position. The outward extension portion 142, located between the main mounting hole 111 and the end mounting hole 112, further enhances the connection strength between the second bushing 14 and the entire mounting structure. The engagement of the second bushing portion 141 with the inside of the end mounting hole 112 achieves initial positioning, while the provision of the second extension portion 142 further clarifies the installation position of the bushing, enabling the second bushing 14 to be accurately aligned with the main mounting hole 111 and the end mounting hole 112 during installation, thus improving installation accuracy.

[0050] In some embodiments of this application, the ice shaver 100 further includes a spring 23 sleeved on the outside of the second shaft portion 216. One end of the spring 23 abuts against the first shaft portion 216, and the other end abuts against the second extension portion 142. It can apply an axial preload to the rotating shaft 21, so that the rotating shaft maintains a relatively stable axial position during operation. The rotating shaft 20 is axially movable within the mounting hole 11. The housing 10 has a mounting hole 11 and a mounting groove 12 that are connected. Ice blocks are placed in the ice tray 30, and the ice tray 30 is detachably installed in the mounting groove 12. The ice pressing plate 22 can extend into the ice pressing plate 22 and press against the ice blocks in the ice tray 30. The spring 23 can push the rotating shaft 21 to move closer to the ice tray 30, and the spring 23 is used to provide a clamping force to the ice pressing plate 22.

[0051] In some embodiments of this application, the second extension 142 has a second extending edge 1421 extending radially outward along the end of the second bushing portion 141, and a second axial edge 1422 extending axially towards the main mounting hole 111 along the outer end of the second extending edge 1421. The second extending edge 1421 and the second axial edge 1422 form a receiving groove 1424 that matches the other end of the spring 23. The receiving groove 1424 can accurately position the spring 23, ensuring that the spring is accurately in a predetermined position after installation. The positioning effect of the receiving groove 1424 on the spring 23 allows the spring 23 to more effectively transmit force to the second bushing 14 during operation; the axial force on the spring 23 can be evenly distributed to the second extending edge 1421 and the second axial edge 1422 through the receiving groove 1424, avoiding excessive local stress and enhancing the structural stability of the connection between the second bushing 14 and the spring 23.

[0052] In some embodiments of this application, the second extension 142 further includes a second outer extension edge 1423 extending radially outward along the second axial direction from the end of 1422. The outer diameter of the second outer extension edge 1423 is larger than the radial dimension of the main mounting hole 111. The second outer extension edge 1423 can increase the contact area and connection strength between the second bushing 14 and the main housing 15, making the second bushing 14 more stable during the operation of the ice shaver.

[0053] In some embodiments of this application, the rotating shaft 21 is axially movable within the mounting hole 11, and the radial dimension of the first shaft portion 216 is larger than the inner diameter of the second axial line 142. When the rotating shaft 21 moves away from the ice compartment 30, it is stopped by the second axial line 142 when the first shaft portion 216 reaches the second bushing 14, thus clearly defining the range of movement of the rotating shaft in that direction. This avoids component damage or functional failure that may result from excessive movement of the rotating shaft 21, ensuring the stability of the internal structure of the ice shaver and the relative positional accuracy between the components, enabling the ice shaver to operate normally and reliably. The stopping effect of the second axial line 142 on the first shaft portion 216 prevents the rotating shaft 21 from colliding or interfering with other important components during movement. During the ice shaving process, the positional stability of the rotating shaft 21 is crucial for the ice shaving effect. Limiting the range of movement of the rotating shaft 21 ensures that the ice shaver blades work continuously and stably in the appropriate position, avoiding problems such as uneven ice shaving thickness and decreased ice shaving efficiency caused by changes in the position of the rotating shaft 21.

[0054] In some embodiments of this application, a radially inwardly extending inner edge 113 is provided at one end of the main mounting hole 111 near the second bushing 14, and the inner diameter of the inner edge 113 is matched with the radial dimension of the first shaft portion 216.

[0055] In some embodiments of this application, the ice shaver 100 further includes a rocker arm 24 sleeved on the outer side of the other end of the rotating shaft 21. The rocker arm 24 has a mounting hole 241, and the outer side of the rotating shaft 21 has an axially extending limiting groove 212. The wall of the mounting hole 241 has a limiting protrusion 2411 that matches the limiting groove 212. The rocker arm 24 is sleeved on the outer side of the other end of the rotating shaft 21. Through the matching structure of the mounting hole 241 on the rocker arm 24, the limiting groove 212 on the outer side of the rotating shaft 21, and the limiting protrusion 2411 on the wall of the mounting hole 241, the rocker arm 24 can be effectively connected to the rotating shaft 21. When the user operates the rocker arm 24, the movement of the rocker arm 24 can be accurately transmitted to the rotating shaft 21 through the cooperation of the limiting protrusion 2411 and the limiting groove 212, thereby driving the rotating shaft 21 to perform rotation or axial movement, realizing the linkage between the rocker arm 24 and the rotating shaft 21.

[0056] In some embodiments of this application, the rocker arm 24 is detachably mounted on the rotating shaft 21. The ice shaver 100 also includes an assembly head 25 for limiting the axial movement of the rocker arm 24 away from the rotating shaft 21. The assembly head 25 is detachably fixed to the other end of the rotating shaft 21. The assembly head 25 and the rotating shaft 21 are fixed by a threaded connection. The rotating shaft 21, the ice pressing plate 22, the spring 23, the rocker arm 24, and the assembly head 25 constitute a rotating shaft assembly. The rocker arm 24 is detachably mounted and has the assembly head 25, which allows the rotating shaft assembly to be disassembled, facilitating the cleaning of the ice pressing plate and the cleaning of the mounting groove 12. When disassembling the rotating shaft assembly, the ice tray 30 is removed from one end of the housing 10, and the assembly head 25 and the rocker arm 24 are removed from the other end; then the ice pressing plate 22, the rotating shaft 21, and the spring 23 are removed together from the other end.

[0057] In some embodiments of this application, the ice shaver 100 further includes a handle 26 located at the end of the rocker arm 24 away from the rotating shaft 21. The handle 26 is rotatably mounted on the rocker arm 24. The axial orientation of the handle 26 facilitates the rotation of the rotating shaft 21 and the installation and removal of the ice compartment 30. When the user operates the handle 26, its relative rotation allows for better transmission of the force applied by the user to the rocker arm 24 and the rotating shaft 21.

[0058] In some embodiments of this application, the ice shaver 100 also includes a detachable ice outlet shell 35 installed at the end of the ice compartment 30. The ice outlet shell 35 is detachably installed at the end of the ice compartment 30 and can be easily removed when the ice shaver 30 needs to be cleaned.

[0059] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
