[0002] Smoothies, a common ingredient in cold drinks, are an essential treat for cooling down in the hot summer. Traditional ice shavers are typically hand-cranked, which is time-consuming and labor-intensive. Therefore, electric ice shavers have emerged, which shave ice by rotating an inner cylinder, such as the one disclosed in Chinese patent CN2819134Y. However, this type of ice shaver still suffers from slow and incomplete ice dispensing, resulting in poor shaving efficiency. Furthermore, the snap-fit ​​assembly makes the overall structure less robust and durable. Utility Model Content

The storage part is located on the rear side of the open inner shell body. The top surface of the storage part has a recessed groove for placing a spoon. The upper edge of the inner shell is located at the top of the inner shell body and the outer periphery of the storage part, and is connected and fixed below the top opening of the mounting chamber. The inner cylinder is cylindrical and rotatably mounted in the rotating chamber of the inner shell body; the inner cylinder has an ice inlet chamber with an open top surface, and the ice inlet chamber has a spiral inclined plate for guiding ice blocks; the top surface of the spiral inclined plate is smooth, while the bottom surface is densely covered with several downward-protruding protrusions; the outer periphery of the top of the inner cylinder is fitted with a ring gear for fixing, and the side wall of the rotating chamber has a gear hole that connects to the mounting chamber; The gear set and drive motor are installed in the mounting chamber. The drive motor drives the gear set to rotate, and the gear set meshes with the ring gear through the gear hole.

[0006] Furthermore, a hollow rotating shaft tube is provided in the middle of the bottom of the rotating chamber, and the blade mounting port is located on one side of the rotating shaft tube; the middle of the ice inlet chamber has a rotating sleeve that extends vertically and passes through both ends, and the rotating sleeve is fitted around the outer periphery of the rotating shaft tube.

[0007] Furthermore, the top of the rotating shaft tube is provided with a bayonet, and the lower part of a snap-fit ​​component is detachably connected to the bayonet. The middle part of the snap-fit ​​component has a radially outwardly protruding snap-fit ​​edge, which is limited to the top of the rotating sleeve sleeved on the outer periphery of the rotating shaft tube.

[0008] Furthermore, the inner cylinder has two spiral inclined plates arranged symmetrically along the rotating sleeve in the ice inlet chamber.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] like Figure 1 and Figure 6 As shown, the structure of an electric ice shaver in this embodiment includes an outer shell 1, an inner shell 2, an inner cylinder 3, a ring gear 4, a gear set 5, a drive motor 6, a blade 7, a push switch 8, and a control board 9.

[0018] like Figure 2 and Figure 4 As shown, the outer shell 1 includes a front shell 11, a rear shell 12, an upper cover 13, and a lower cover 14; the front shell 11 and the rear shell 12 are fastened together and can be connected by screws 20, forming an installation chamber 15 with openings at both the top and bottom. The upper cover 13 is detachably fastened to cover the top opening of the installation chamber 15, and the lower cover 14 is installed to seal the bottom opening of the installation chamber 15.

[0019] In this embodiment, the outer shell 1 can be approximately an elliptical cylindrical structure, and the upper and lower openings of the mounting chamber 15 can both be slightly wider at the rear and have an elliptical shape.

[0020] The lower part of the front outer wall of the front housing 11 is recessed to form an ice-receiving chamber 16. The ice-receiving chamber 16 has a "C"-shaped inner wall 17 that separates the ice-receiving chamber 16 from the installation chamber 15. The top wall of the inner wall 17 has an ice outlet 171 that communicates upward with the installation chamber 15. The ice-receiving chamber 16 can hold containers such as bowls 10 for collecting ice.

[0021] The inner shell 2 is installed on the upper part of the installation chamber 15. The inner shell 2 includes an inner shell body 21, a storage part 22, and an inner shell upper edge 23.

[0022] The inner shell body 21 has a rotating chamber 211 with an open top. A hollow rotating shaft tube 212 is provided on the upper part of the bottom of the rotating chamber 211. The bottom of the rotating chamber 211 is provided on one side of the rotating shaft tube 212, which is aligned and connected to the ice outlet 171. The blade 7 with the blade exposed on the bottom surface of the rotating chamber 211 is installed in the blade mounting port 213. The blade 7 can be locked and fixed to the blade mounting port 213 by means of the blade seat 71 and screws 20.

[0023] The inner shell body 21 is mainly located above the inner wall 17 on the front side of the mounting chamber 15, while the storage part 22 can be a plate-shaped structure formed on the rear side of the open inner shell body 21. The top surface of the storage part 22 is recessed with a trough 221, which can hold a spoon 30 for easy retrieval and use.

[0024] The upper edge 23 of the inner shell is located at the top of the inner shell body 21 and the outer periphery of the storage part 22, and can be snapped into the annular slot 151 provided below the top opening of the mounting chamber 15 to install the inner shell 2 into the mounting chamber 15.

[0025] The inner cylinder 3 is cylindrical, and has an ice-inlet chamber 31 with an open top surface inside. The ice-inlet chamber 31 has a rotating sleeve 311 extending vertically and penetrating at both ends in the middle. The rotating sleeve 311 of the inner cylinder 3 can be sleeved on the outer circumference of the rotating shaft tube 212, so that the inner cylinder 3 can be rotatably assembled in the rotating chamber 211 of the inner shell body 21. Thus, the inner cylinder 3 can rotate about the rotating shaft tube 212 as an axis. The top of the rotating shaft tube 212 can be provided with a snap 2121, and the snap 2121 is detachably connected to the lower part of the snap fastener 24. The middle part of the snap fastener 24 has a radially outwardly protruding snap edge 241, which is limited to the top of the rotating sleeve 311 sleeved on the outer circumference of the rotating shaft tube 212, thereby limiting the inner cylinder 3 in the rotating chamber 211.

[0026] See Figure 5 and Figure 6 The inner cylinder 3 has two spiral inclined plates 312 arranged symmetrically along the rotating sleeve 311 in the ice inlet chamber 31. The two spiral inclined plates 312 are staggered at their ends to form an ice inlet 313. The ice inlet 313 connects the space between the inner wall of the rotating chamber 211 and the space below the spiral inclined plates 312. The top surface of the spiral inclined plates 312 is smooth, which facilitates the guidance of the ice block to slide down into the ice inlet 313. The bottom surface of the spiral inclined plates 312 is densely covered with several downward protrusions 3121. When the inner cylinder 3 rotates, the spiral inclined plates 312 apply a downward force to the ice block below, and the protrusions 3121 increase the friction with the ice block. This can fully drive the ice block between the spiral inclined plates 312 and the bottom surface of the rotating chamber 211 to move, thereby improving the ice cutting efficiency of the ice block and the blade 7.

[0027] The inner cylinder 3 is fitted with a ring gear 4 on its outer periphery. The inner wall of the ring gear 4 is provided with a number of slots 41 spaced apart in the circumferential direction. The inner cylinder 3 is provided with a corresponding locking block 32 that engages with the slots 41. The outer wall of the ring gear 4 is provided with a number of teeth spaced apart in the circumferential direction. The rotating chamber 211 is provided with a gear hole 2111 on the side wall near the storage part 22. The gear hole 2111 is laterally connected to the rotating chamber 211 and the mounting chamber 15.

[0028] like Figure 2 The gear set 5 and the drive motor 6 can be installed in the mounting chamber 15 and located on one side of the inner shell body 21 below the storage section 22. The gear set 5 includes at least four double gears 51 that mesh sequentially in the top, bottom, left, and right directions. The drive motor 6 drives the lowermost double gear 51 connected to the gear set 5, and the uppermost double gear 51 meshes with the ring gear 4 in the rotating chamber 211 through the gear hole 2111. Thus, by driving the gear set 5 to rotate by the drive motor 6, the ring gear 4 can be driven to rotate, which in turn drives the inner cylinder 3 to rotate in the rotating chamber 211 of the inner shell 2, thereby pushing the ice block to move and cooperate with the blade 7 to cut, so as to realize the ice discharge from the ice outlet 171.

[0029] In this embodiment, a motor bracket 61 can be installed below the storage section 22, and the drive motor 6 can be installed inside the motor bracket 61. The motor bracket 61 is also provided with two rotating shafts 52, and two double gears 51 are respectively sleeved on the two rotating shafts 52. Wear-resistant pads 53 can be provided between each double gear 51 to form the gear set 5.

[0030] like Figure 4 The push switch 8 and the control board 9 can be installed in the mounting chamber 15 below the storage section 22. The control board 9 is electrically connected to the push switch 8 and the drive motor 6 respectively. The push switch 8 can be a micro switch.

[0031] The top of the storage section 22 may have a through hole 222 that connects the upper and lower parts. The push switch 8 can be locked to the bottom of the storage section 22 and the top of the push switch 8 is provided with a control key 81 located in the through hole 222. The bottom of the upper cover 13 may be provided with a downward protruding insert 131. When the upper cover 13 is closed on the top opening of the mounting chamber 15 above the inner shell 2, the insert 131 is aligned and inserted into the through hole 222 and presses against the control key 81 to trigger the push switch 8. Then, the drive motor 6 is controlled to rotate through the control board 9, so as to automatically trigger the inner cylinder 3 to rotate for shaved ice after the upper cover 13 is closed.

[0032] like Figure 2 In this embodiment, a temperature controller 62 may also be installed on one side of the drive motor 6. The temperature controller 62 is electrically connected to the control board 9 and can be used to detect the operating temperature of the drive motor 6 for overheat protection, etc.

[0033] like Figure 4 In this embodiment, the bottom of the upper cover 13 may be provided with a ring of downwardly protruding snap-fit ​​portion 132, which can completely cover and snap onto the top opening of the outer shell 1, thus simultaneously shielding and protecting the opening of the inner cylinder 3 and the storage part 22. At the same time, the upper cover 13 may be made of transparent material to facilitate observation of the remaining ice; a handle 133 may be formed in the middle of the top surface of the upper cover 13 to facilitate picking up the upper cover 13.

[0034] In this embodiment, the bottom of the lower cover 14 may be provided with silicone feet 141 to improve the stability of the product when placed on a table or desktop.

[0035] In summary, the electric ice shaver of this embodiment achieves better product structural strength by setting the outer shell 1 composed of the front shell 11 and the rear shell 12. The upper cover 13 can be fastened by pressing it. After the upper cover 13 is closed, its insert rod 131 triggers the press switch 8 and controls the drive motor 6 to move through the control board 9. The drive motor 6 drives the gear set 5 to drive the ring gear 4 and the inner cylinder 3 to rotate, thereby achieving the purpose of automated ice shaving. The shaved ice can automatically fall from the ice outlet 171 into the bowl 10 of the ice receiving chamber 16. After the ice is shaved, the upper cover 13 can be opened to take out the spoon 30 from the storage part 22 for use. It is convenient to use and has a good user experience. Moreover, after the upper cover 13 is opened, the insert rod 131 moves away from the press switch 8, causing the drive motor 6 and the inner cylinder 3 to stop rotating, which also ensures the safety of use.
