Description

Technical Field

[0001] This application belongs to the field of ice crushing device technology, and particularly relates to an ice crusher. Background Technology

[0002] An ice crusher, also known as an ice shaver, can shave large blocks of ice into ice shavings or break large blocks of ice into smaller ice cubes for use in making cold drinks and other foods.

[0003] Most existing ice shavers work by rotating the ice shaver container and the ice together, but the ice shaver container has the disadvantage of being damaged by melting. There are also ice shavers that use side stirring blades, but this type of ice shaver is limited and can only shave ice at low speeds, resulting in low shaving efficiency.

[0004] For example, Chinese Patent Publication No. CN101479540A discloses an ice shaving machine, which includes an ice shaving chamber, a rotating blade for rotating ice fed into the ice shaving chamber, a rotating hopper that rotates coaxially with the rotating blade, and a rotating ice storage chamber. Since both the hopper and the ice storage chamber need to rotate during the ice shaving process, prolonged operation can adversely affect the structural stability of the rotating hopper and the rotating blade themselves, leading not only to damage of the melt but also a reduction in ice shaving efficiency. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the purpose of this application is to provide an ice crusher with stable structure and high ice crushing efficiency.

[0006] The technical solution adopted in this application embodiment is an ice crusher, including a base and a power output device disposed within the base, the ice crusher further including:

[0007] An ice crushing container is fixed to the base, and the bottom wall of the ice crushing container is provided with an ice crushing outlet;

[0008] An ice-crushing blade, which is fixed to the bottom wall of the ice-crushing container;

[0009] A stirring paddle is disposed inside the ice crushing container and above the ice crushing blade. The stirring paddle is connected to the power output device and rotates under the drive of the power output device to stir up the ice blocks in the ice crushing container and cooperate with the ice crushing blade to crush the ice.

[0010] The ice crusher in this embodiment uses a stirring paddle to agitate ice blocks, and then works with ice crushing blades to shave, cut, and impact ice to break it into ice sand, achieving efficient ice crushing in multiple ways.

[0011] In an optional embodiment, the power output device includes an output shaft that extends through the bottom of the ice crushing container and into the ice crushing container;

[0012] The stirring paddle includes blades mounted on the output shaft. These blades rotate under the drive of the output shaft. A converging structure is formed on the ice-facing side of the rotating blades. This converging structure gathers ice blocks towards the ice-crushing blade and works in conjunction with the blade to crush the ice. The converging structure effectively pushes the ice blocks towards the ice-crushing blade, improving ice-crushing efficiency.

[0013] In an optional embodiment, the first end of the blade is connected to the output shaft, and the second end of the blade forms a free end. The gathering structure includes a first inclined plane and a second inclined plane that are inclined towards the middle of the blade from both ends and intersect. The included angle between the first inclined plane and the second inclined plane is α, where 90° < α < 180°. The gathering structure is simple and has a good effect on gathering and collecting ice blocks.

[0014] In an optional embodiment, the gathering structure further includes a third inclined surface and a fourth inclined surface. The upper side of the third inclined surface is connected to the top surface of the blade, the lower side of the third inclined surface is connected to the upper side of the first inclined surface, the upper side of the fourth inclined surface is connected to the top surface of the blade, and the lower side of the fourth inclined surface is connected to the upper side of the second inclined surface. The angle between the third and fourth inclined surfaces is β, where 90° < β < 180°; the angle between the third inclined surface and the top surface of the blade is γ, where 90° < γ < 180°; and the angle between the fourth inclined surface and the top surface of the blade is δ, where 90° < δ < 180°, and δ is equal to γ. The formation of the third and fourth inclined surfaces can further enhance the gathering effect on the ice blocks.

[0015] In an optional embodiment, a plurality of ice-crushing blades are provided on the bottom wall of the ice-crushing container. These blades are arranged radially around the output shaft. Each ice-crushing blade includes a back section and a cutting edge extending radially along the output shaft, and the cutting edge is located downstream of the back section in the direction of blade rotation. The simultaneous operation of multiple ice-crushing blades improves ice-crushing efficiency. Furthermore, by arranging the ice-crushing blades radially with their cutting edges perpendicular to the direction of blade rotation, the blades can cut and break ice blocks from the front, further improving ice-breaking efficiency.

[0016] In an optional embodiment, the bottom wall of the ice crushing container is provided with a plurality of ice crushing outlets, each corresponding to a plurality of ice crushing blades and positioned close to the ice crushing blades. Furthermore, in the direction of blade rotation, each ice crushing outlet is located upstream of its corresponding ice crushing blade. By providing adjacent ice crushing outlets for each ice crushing blade, ice crushing can be promptly discharged from the ice crushing container.

[0017] In an optional embodiment, the bottom wall of the ice crushing container is recessed downwards near each ice crushing outlet to form a recess, the recess being located upstream of the corresponding ice crushing outlet in the direction of blade rotation; and / or

[0018] The ice-crushing blade is embedded in the bottom wall of the ice-crushing container, with its upper side flush with the bottom wall, and the bottom side of the paddle is infinitely close to the bottom wall of the ice-crushing container. The recessed design allows the paddle to push ice blocks towards the ice-crushing blade; the low proximity of the paddle's bottom side to the bottom wall of the ice-crushing container effectively sweeps all ice fragments out, leaving no residual ice.

[0019] In an optional embodiment, the outer surface of one end of the output shaft located inside the ice crushing container is composed of a plurality of sequentially connected first inclined surfaces, so that the end of the output shaft forms a helical truncated pyramid with a lower outer diameter larger than the upper outer diameter, and the direction of rotation of the helical truncated pyramid is opposite to the direction of rotation of the output shaft.

[0020] The impeller has a shaft hole, the wall of which is composed of multiple sequentially connected second inclined surfaces to form a spiral polygonal hole that fits the spiral truncated pyramid. The impeller is mounted on the spiral truncated pyramid of the output shaft through the shaft hole. During stirring, the impeller will not loosen; when not stirring, it can be easily disassembled and reassembled on the output shaft for convenient cleaning.

[0021] In an optional embodiment, the base includes a base portion, a side arm portion extending upward from one side of the base portion, and a top arm portion located above the base portion and connected to the upper end of the side arm portion, wherein a cavity for placing an ice cup is formed between the top arm portion and the base portion.

[0022] The ice crushing container is disposed on the top arm, and the top arm is provided with a through-hole corresponding to the ice crushing outlet;

[0023] The power output device is located inside the side arm to avoid the bottom of the ice crushing container; or, the power output device is located inside the top arm and avoids the ice crushing outlet. The base structure is reasonable, which facilitates the installation of the ice crushing container and the power output device on it, and with the overall height of the machine fixed, the ice crushing container can be made taller to increase the ice capacity.

[0024] In an optional embodiment, the ice crushing container includes a container body and a safety cap for sealing or opening the container body;

[0025] The ice crusher also includes a safety switch assembly, which comprises an upper connecting rod, a lower connecting rod, a spring, and a switch. The upper connecting rod is located within the side wall of the container body and can move up and down within the side wall. The lower connecting rod, spring, and switch are all located within the base, with the upper end of the lower connecting rod corresponding to the lower end of the upper connecting rod, and the lower end of the lower connecting rod corresponding to the switch. When the safety cover is placed on the container body, the safety cover pushes the upper connecting rod downwards, which in turn pushes the lower connecting rod downwards and triggers the switch, allowing the ice crusher to start. The spring acts on the lower connecting rod, applying an upward force to it. When the safety cover of the ice crusher container is opened, the spring pushes the lower connecting rod upwards, releasing the trigger on the switch and preventing the ice crusher from starting. This safety switch assembly enhances safety and prevents accidental hand injuries.

[0026] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: The ice crusher of the embodiments of this application uses the rotation of the stirring paddle to stir the ice block, and then cooperates with at least one ice crushing blade fixed at the bottom of the ice crushing container to perform planing, cutting and impact to crush the ice into sand, thereby achieving efficient ice crushing in multiple ways, and then the crushed ice is discharged in time through the ice crushing outlet at the bottom of the ice crushing container; the ice crusher of this application has a clever and reasonable structural design, low cost and high ice crushing efficiency.

[0048] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0049] like Figures 1 to 3 ,and Figures 7 to 8 As shown in the figure, this application provides an ice crusher for crushing ice into slush or small ice cubes.

[0050] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the ice crusher includes a base 1, a power output device 2, an ice crushing container 3, ice crushing blades 4, and a stirring paddle 5. The power output device 2 is located inside the base 1 and provides rotational power to the stirring paddle 5. The ice crushing container 3 is fixed to the base 1, and its bottom wall has an ice crushing outlet 311. The ice crushing blades 4 are fixed to the bottom wall of the ice crushing container 3. The stirring paddle 5 is located inside the ice crushing container 3 and above the ice crushing blades 4. The stirring paddle 5 is connected to the power output device 2 and rotates under its drive to agitate the ice in the ice crushing container 3 and work with the ice crushing blades 4 to crush the ice.

[0051] The ice crusher of this application utilizes the cooperation of a stirring paddle 5 and an ice-crushing blade 4 to crush ice. Since the rotational speed of the stirring paddle 5 is not limited, it can rotate at high speed, which can improve the ice cutting efficiency. Moreover, during the ice crushing process, the ice crushing container 3 remains stationary, which not only avoids damage to the molten adhesive but also improves the stability of the overall structure.

[0052] In some embodiments, the power output device 2 includes an output shaft 21 that extends through the bottom of the ice crushing container 3 and into the ice crushing container 3. The stirring paddle 5 includes a blade 51 mounted on the output shaft 21. The blade 51 and the output shaft 21 can be detachably or fixedly connected. The blade 51 can rotate under the drive of the output shaft 21. When the blade 51 rotates, a gathering structure is formed on the ice-facing side. The gathering structure is used to collect ice blocks to the ice crushing blade 4 and cooperate with the ice crushing blade 4 to crush the ice. By providing a gathering structure on the ice-facing side of the blade 51, ice blocks can be collected and pushed towards the ice crushing blade 4, improving the efficiency of ice shaving.

[0053] In an optional embodiment, the first end of the blade 51 is connected to the output shaft 21, and the second end of the blade 51 forms a free end. For example... Figure 4 and Figure 5 As shown, the gathering structure includes a first inclined surface 511 and a second inclined surface 512, which are inclined from both ends of the blade 51 towards the middle of the blade 51 and intersect each other. The included angle between the first inclined surface 511 and the second inclined surface 512 is α, where 90° < α < 180°. This gathering structure is simple and easy to manufacture. Furthermore, the gathering center 515 of the gathering structure is located in the middle of the blade 51 and gradually converges inward from both ends of the blade 51 towards the middle, resulting in a good gathering effect on ice blocks and making it more suitable for use with the ice crusher 4 to improve ice crushing efficiency.

[0054] Furthermore, continue to combine Figure 4 The folding structure may further include a third inclined surface 513 and a fourth inclined surface 514. The upper side of the third inclined surface 513 is connected to the top surface of the blade 51, the lower side of the third inclined surface 513 is connected to the upper side of the first inclined surface 511, the upper side of the fourth inclined surface 514 is connected to the top surface of the blade 51, and the lower side of the fourth inclined surface 514 is connected to the upper side of the second inclined surface 512. The included angle between the third inclined surface 513 and the fourth inclined surface 514 is β, 90° < β < 180°; the included angle between the third inclined surface 513 and the top surface of the blade 51 is γ, 90° < γ < 180°; the included angle between the fourth inclined surface 514 and the top surface of the blade 51 is δ, 90° < δ < 180°, and δ is equal to γ. That is, the third inclined surface 513 and the fourth inclined surface 514 gradually slope outward from the top of the blade 51 and extend to connect with the first inclined surface 511 and the second inclined surface 512 respectively. The formation of the third inclined surface 513 and the fourth inclined surface 514 can further increase the gathering effect of ice blocks and facilitate the use of the ice crushing blade 4 to improve the ice crushing effect.

[0055] In some embodiments, such as Figure 6 As shown, the bottom wall of the ice crushing container 3 is provided with multiple ice crushing blades 4, which are arranged radially around the output shaft 21. Each ice crushing blade 4 includes a back and a cutting edge extending radially along the output shaft 21, and is positioned in the rotation direction of the blade 51. Figure 6The direction indicated by the middle arrow is the rotation direction of the blade 51, and the cutting edge is located downstream of the back. Multiple ice-crushing blades 4 are arranged radially along the output shaft 21, such that the cutting edge of the ice-crushing blade 4 is perpendicular to the rotation direction of the blade 51. The ice-crushing blade 4 can cut and break ice blocks from the front, improving ice-crushing efficiency. Furthermore, using multiple ice-crushing blades 4 in conjunction further enhances the cutting efficiency of ice blocks.

[0056] In some embodiments, continue to combine Figure 6 The bottom wall of the ice crushing container 3 is provided with multiple ice crushing outlets 311. Each ice crushing outlet 311 corresponds to one of the multiple ice crushing blades 4 and is positioned close to the ice crushing blades 4. In the rotation direction of the paddle 51, the ice crushing outlet 311 is located upstream of its corresponding ice crushing blade 4. By providing close-proximity ice crushing outlets 311 for each ice crushing blade 4, the broken ice shards or shaved ice sand can be discharged from the ice crushing container 3 in a timely manner, preventing ice shards and ice sand from accumulating in the ice and affecting the ice crushing efficiency and effect.

[0057] The shape of the ice crushing outlet 311 can be designed to be approximately rectangular, similar to the ice crusher 4. The ice crushing outlet 311 and the ice crusher 4 are aligned at both ends in the radial direction of the output shaft 21, so that the ice crushed by the ice crusher 4 can be discharged from the ice crushing outlet 311 in a timely manner. Moreover, compared to placing the ice crushing outlet 311 on the side of the ice crushing container 3, the ice discharge is smoother.

[0058] In some embodiments, such as Figure 6 As shown, the bottom wall of the ice crushing container 3 is recessed downwards near each ice crushing outlet 311 to form a recess 312. The recess 312 is located upstream of the corresponding ice crushing outlet 311 in the rotation direction of the blade 51. By setting the recess 312, it is easier for the blade 51 to push the ice blocks towards the ice crushing blade 4, and more ice blocks will gather near the ice crushing blade 4, thus improving the ice crushing effect.

[0059] The recess 312 can be roughly rectangular, and the two sides of the recess 312 in the radial direction of the output shaft 21 are basically flush with the two sides of the ice crushing outlet 311 in the radial direction of the output shaft 21 to ensure the ice collection effect.

[0060] Continue to combine Figure 6 The gap between the corresponding ice-breaking blade 4 and the recess 312 is formed as an ice-breaking outlet 311, which can improve the ice-breaking efficiency.

[0061] Optionally, the ice-crushing blade 4 is embedded in the bottom wall of the ice-crushing container 3, with its upper side flush with the bottom wall, and the bottom side of the paddle 51 is infinitely close to the bottom wall of the ice-crushing container 3. The side of the paddle 51 facing the bottom wall of the ice-crushing container 3 can be designed as a flat surface, which is infinitely close to the bottom wall of the ice-crushing container 3. In this way, the ice inside the ice-crushing container 3 can be thoroughly cut and broken, and all the ice fragments can be swept out of the ice-crushing container 3, achieving zero residual ice fragments.

[0062] In some embodiments, such as Figures 2 to 4 As shown, the ice crusher includes two blades 51 arranged in a straight line and forming a single unit. The bottom sides of both blades 51 are designed as flat surfaces, positioned very close to the bottom wall of the ice crushing container 3. A shaft hole 52 is provided in the center of the single unit, and the upper end of the output shaft 21 is located in the ice crushing container 3 and passes through the shaft hole 52. It is understood that the number of blades 51 is not limited to two; it can be three, four, or more. When there are three or more blades 51, one end of each blade can be connected to the same central portion, on which the shaft hole 52 is provided, and the blades 51 extend radially along the shaft hole 52.

[0063] like Figure 5 As shown, the outer surface of the upper end of the output shaft 21 (i.e., the end located inside the ice crushing container 3) is composed of multiple sequentially connected first inclined surfaces 211, so that this end of the output shaft 21 forms a helical truncated pyramid with a lower outer diameter larger than the upper outer diameter, and the direction of rotation of the helical truncated pyramid is opposite to the direction of rotation of the output shaft 21. The hole wall of the shaft hole 52 is composed of multiple sequentially connected second inclined surfaces 521, so as to form a helical polygonal hole adapted to the helical truncated pyramid. The blade 51 is assembled onto the helical truncated pyramid of the output shaft 21 through the shaft hole 52. The first inclined surfaces 211 and the second inclined surfaces 521 match each other. When the output shaft 21 drives the blade 51 to rotate for stirring, the blade 51 will not loosen. When the blade 51 stops stirring, it can be easily disassembled from the output shaft 21 for easy cleaning.

[0064] In some embodiments, such as Figure 3 and Figure 8As shown, the base 1 includes a base portion 11, a side arm portion 12 extending upward from one side of the base portion 11, and a top arm portion 13 located above the base portion 11 and connected to the upper end of the side arm portion 12. A cavity 14 for placing an ice-collecting cup 7 is formed between the top arm portion 13 and the base portion 11, and the cavity 14 has an opening on the side of the base 1 so that the ice-collecting cup 7 can be placed into or removed from the cavity 14 through the opening. An ice-crushing container 3 is provided on the top arm portion 13, and the top arm portion 13 has through holes corresponding to a plurality of ice-crushing outlets 311. When the ice-collecting cup 7 is placed in the cavity 14, the vertical projection of the plurality of through holes all falls within the rim of the ice-collecting cup 7, so that the ice crushed in the ice-crushing container 3 can fall into the ice-collecting cup 7 through the ice-crushing outlets 311 and the through holes. The base 1 has a reasonable structure, which facilitates the setting of the ice crushing container 3. Moreover, with the overall height of the machine fixed, the ice crushing container 3 can be made taller to increase the ice capacity.

[0065] exist Figure 2 and Figure 3 In the first embodiment shown, the power output device 2 is located inside the side arm 12 to avoid the bottom of the ice crushing container 3. By placing the power output device 2 inside the side arm 12, the space occupied by the power output device 2 below the ice crushing container 3 can be reduced, thereby reducing the overall height of the ice crusher.

[0066] Continue to combine Figure 2 and Figure 3 In the first embodiment shown, the power output device 2 includes, in addition to the output shaft 21 mentioned above, a motor 22, an output gear 23, a double gear 24, a belt 25, and a pulley 26. The output gear 23 is mounted on the motor shaft of the motor 22 and meshes with the first gear of the double gear 24. The second gear of the double gear 24 is connected to the pulley 26 via the belt 25. The pulley 26 is mounted on the output shaft 21. When ice crushing is required, the motor 22 is started. The motor shaft of the motor 22 drives the output gear 23 to rotate, which in turn drives the double gear 24 to rotate. The double gear 24 then drives the pulley 26 via the belt 25, which in turn drives the output shaft 21 to rotate. The output shaft 21 then drives the stirring paddle 5 to rotate, thus transmitting the power from the motor 22 to the stirring paddle 5, agitating the ice blocks in the ice crushing container 3. The power output device 2 of the first embodiment has a simple and reliable structure, low cost, is easy to manufacture, and provides fast ice crushing speed.

[0067] exist Figure 7 and Figure 8In the illustrated embodiment two, the power output device 2 is located inside the top arm 13 and avoids the ice crushing outlet 311. Besides the output shaft 21 mentioned above, the power output device 2 also includes a motor 22 and a helical gear 27. The motor shaft of the motor 22 has an external thread, is horizontally positioned, and meshes with the helical gear 27, which is mounted on the output shaft 21. When ice crushing is needed, the motor 22 is started. The motor shaft of the motor 22 drives the helical gear 27 to rotate, which in turn drives the output shaft 21 to rotate. The output shaft 21 then drives the stirring paddle 5 to rotate, thus transmitting the power from the motor 22 to the stirring paddle 5, agitating the ice blocks inside the ice crushing container 3. The power output device 2 in embodiment two has a simple and reliable structure, low cost, is easy to manufacture, and has a fast ice crushing speed. Furthermore, although the power output device 2 is located below the ice crushing container 3, it is small in size, compact in structure, and occupies little space.

[0068] like Figure 2 and Figure 7 As shown, a double bearing 28 is provided between the bottom wall of the ice crushing container 3 and the output shaft 21 to allow the output shaft 21 to rotate smoothly relative to the ice crushing container 3. An oil seal 29 is provided between the ice crushing container 3 and the output shaft 21, and the oil seal 29 is located above the bearing 28. By providing the oil seal 29, the leakage of melted ice water in the ice crushing container 3 to the power output device 2 is prevented during the ice crushing process.

[0069] In some embodiments, such as Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the ice crushing container 3 includes a container body 31 and a safety cap 32 for sealing or opening the container body 31. The upper part of the container body 31 is open, and the bottom is closed. The ice crushing outlet 311 and the ice crushing blade 4 are both located on the bottom of the container body 31, and the stirring paddle 5 is located near the bottom of the container body 31. The safety cap 32 is used to seal or open the upper opening of the container body 31.

[0070] The ice crusher also includes a safety switch assembly 6, which comprises an upper connecting rod 61, a lower connecting rod 62, a spring 63, and a switch 64. The upper connecting rod 61 is located inside the side wall of the container body 31, with its upper end extending beyond the upper end of the container body 31. The upper connecting rod 61 can move up and down within the side wall. The lower connecting rod 62, the spring 63, and the switch 64 are all located inside the base 1. The upper end of the lower connecting rod 62 corresponds to the lower end of the upper connecting rod 61, and the lower end of the lower connecting rod 62 corresponds to the switch 64. When the safety cover 32 is placed on the container body 31, the safety cover 32 presses against the upper end of the upper connecting rod 61 and pushes the upper connecting rod 61 downward. The lower end of the upper connecting rod 61 acts on the lower connecting rod 62, pushing the lower connecting rod 62 downward and triggering the switch 64. This creates a closed circuit in the circuit containing the switch 64, allowing the ice crusher to start. Spring 63 acts on the lower connecting rod 62, applying an upward force to it. When the safety cover 32 of the ice crushing container 3 is opened, spring 63 pushes the lower connecting rod 62 upward, releasing the trigger on switch 64. The circuit containing switch 64 is disconnected, preventing the ice crusher from starting. By incorporating the safety switch assembly 6, the ice crusher can only be started when the safety cover 32 is on the container body 31, improving safety during use.

[0071] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
