More specifically, in the embodiment, the shaft seat 1 includes a shaft seat bottom 11 disposed at the bottom of the shaft seat 1 and a rotary drum protective casing 12 formed by extending upward from the periphery of the shaft seat bottom 11, the rotary drum 3 is embedded inside the rotary drum protective casing 12, and the rotary drum protective casing 12 is disposed to protect the rotary drum 3 and prevent unnecessary potential safety hazard caused by rotation of the rotary drum 3; it is of course understood that in some simplified embodiments the shaft receptacle 1 may also comprise only the shaft receptacle bottom 11, i.e. the periphery of the drum 3 is not protected. The fixed shaft 2 is fixedly arranged on the shaft base bottom 11, and as shown in fig. 3, a fixed end 20 of the fixed shaft 2 penetrates through the shaft base bottom 11 and is locked and fixed through a screw; of course, in other embodiments, the fixed shaft 2 can be fixed to the base 11 in other manners.

As shown in fig. 4, 5 and 6, the ice crusher according to the present invention has an ice blade assembly inside the rotating drum 3, wherein the ice blade assembly includes at least one fixed ice blade 51 fixed on the fixed shaft 2 and at least one rotating ice blade 52 fixed on the inner wall of the rotating drum 3 and capable of rotating with the rotating drum 3; the drum 3 has a first direction of rotation a for cutting ice cubes, and when the drum 3 is rotated in the first direction of rotation a, the rotating ice blade 52 makes a cutting movement relative to the stationary ice blade 51 to cut whole ice located inside the drum 3 into crushed ice.

Specifically, in the present embodiment, the cross section of the fixed shaft 2 may be configured to be non-circular, for example, may be configured to be hexagonal or other shapes, one end of the fixed blade 51 is provided with a fixing hole 511 matching the cross section of the fixed shaft 2, the end with the fixing hole 511 is a fixed end of the fixed blade 51, the fixed blade 52 is sleeved on the fixed shaft 2 through the fixing hole 511 and fixed at a specific position on the fixed shaft 2, the fixed blade 51 has a blade portion for cutting whole ice, and the blade portion is formed by extending the fixed end towards one side inner wall of the drum 3; the stationary blade 51 according to the present invention is formed only on one side of the stationary shaft 2. The fixed ice blade 51 provided in the above manner has the following advantages: once the stationary blade 51 is damaged, maintenance can be rapidly performed by replacement. Of course, in other embodiments, the stationary blade 51 may be fixed to the stationary shaft 2 at a specific position by welding or other mechanical fixing means.

In this embodiment, the rotating ice blade 52 is provided with a first rotating hole 521, the rotating ice blade 52 is rotatably disposed on the fixed shaft 2 through the first rotating hole 521, and both ends of the rotating ice blade 52 are fixed on the inner wall of the rotating drum 3. In the implementation process, the rotary drum 3 is provided with a groove structure for fixing two ends of the rotary ice skate 52, and two ends of the rotary ice skate 52 are embedded in the groove structure to be fixedly connected with the rotary drum 3. Of course, in other embodiments, the rotating ice blade 52 can be indirectly fixed inside the drum 3, and a specific implementation manner thereof can be referred to later.

Referring to fig. 5, inside the drum 3, the fixed blades 51 and the rotating blades 52 are staggered from top to bottom. Specifically, in the present embodiment, two fixed blades 51 and two rotating blades 52 are disposed inside the drum 3, and the rotating blades 52, the fixed blades 51, the rotating blades 52, and the fixed blades 51 are alternately disposed in parallel in the direction from top to bottom. As a preferred embodiment of the present invention, all the fixed blades 51 constituting the blade assembly are stacked and spaced in the vertical direction, and reference is also made to this design for all the rotating blades 52.

In the implementation process, a user generally has a certain requirement on the size of the crushed ice inside the drum 3, and based on this, the horizontal planes of the fixed ice blades 51 and the rotating ice blades 52 which are arranged in a staggered manner have a certain distance size. In the implementation of the present embodiment, the distance between the stationary blades 51 and the rotating blades 52 is smaller than the size of the whole ice and larger than the size of the crushed ice, so that the whole ice is prevented from being pushed out from between the two adjacent stationary blades 51 by the rotating blades 52 without being crushed. More specifically, a

gasket

74, 75, 76 for isolating the fixed blade 51 from the rotating blade 52 is further disposed between the fixed blade 51 and the rotating blade 52, wherein the rotating blade 52 can be sleeved on the periphery of the gasket and rotate around the gasket.

Referring to fig. 2 and 3, the top of the revolving drum 3 in the ice crusher of the present invention is provided with an ice inlet 30 for ice cubes to enter, the bottom of the shaft seat 1 is provided with an ice outlet 10 for ice cubes to exit, and the ice inlet 30 and the ice outlet 10 are arranged in a staggered manner in the first rotation direction a.

Specifically, an ice inlet baffle 50 is arranged above the drum 3, the ice inlet baffle 50 is fixedly arranged on the fixed shaft 2, the specific fixing mode can refer to the arrangement mode of the fixed ice blade 51, and a gasket 73 for isolation is arranged between the ice inlet baffle 50 and the fixed ice blade 51 or the rotating ice blade 52 adjacent to the lower side of the ice inlet baffle. In this embodiment, the ice inlet baffle 50 is provided with a substantially fan-shaped opening which constitutes the ice inlet 30, the ice inlet 30 is located at one side of the fixed shaft 2, and the whole ice to be processed on the top of the rotary drum 3 enters the interior of the rotary drum 3 through the ice inlet 30. The pedestal base 11 is also provided with a substantially fan-shaped opening which constitutes the ice discharge port 10, and crushed ice processed by the fixed ice blade 51 and the rotating ice blade 52 is discharged through the ice discharge port 10. In other embodiments of the present invention, the ice inlet 30 and the ice outlet 10 may be designed in other shapes, and are not limited to the fan-shaped structure.

In the present invention, in order to prevent ice cubes entering the interior of the drum 3 through the ice inlet 30 from being directly discharged through the ice discharge port 10, the ice inlet 30 and the ice discharge port 10 are arranged in a staggered manner in the first rotation direction a; preferably, the ice discharge opening 10 is also located at one side of the fixed shaft 2.

In a specific implementation process, the size of the projection overlapping part of the ice inlet 30 and the ice discharge port 10 in the vertical direction is smaller than that of the whole ice. As shown in fig. 8 and 9, in the present embodiment, the projections of the staggered ice inlet 30 and the ice discharge port 10 in the vertical direction have an overlapping portion a, but the size of the overlapping portion a is smaller than that of whole ice, so that the whole ice entering from the ice inlet 30 is prevented from directly falling into the ice discharge port 10 and being discharged. It is understood that in other embodiments of the present invention, the projections of the staggered ice inlets 30 and the ice discharge opening 10 in the vertical direction do not overlap (it is understood that the size of the overlapping portion a is 0), and at this time, the whole ice entering from the ice inlets 30 cannot directly fall into the ice discharge opening 10.

In the present invention, the fixed ice blade 51 and the rotary ice blade 52 both have a blade edge side for cutting ice cubes, and when the drum rotates in the first rotational direction a to cut ice cubes, the blade edge sides of the rotary ice blade 52 and the fixed ice blade 51 press the ice cubes together. Referring to fig. 7 and 8, the stationary blade 51 has a first blade side 510, and the rotating blade 52 has a second blade side 520. In this particular embodiment, the first blade edge side 510 and the second blade edge side 520 are both arranged in a saw-tooth configuration, and in the first rotational direction a, the first blade edge side 510 and the second blade edge side 520 are arranged in an opposite direction; specifically, in the first rotation direction a, the first blade edge side 510 is disposed at the rear side of the fixed ice blade 51, and the second blade edge side 520 is disposed at the front side of the rotating ice blade 52 (the rotating ice blade 52 has two blade structures disposed at two sides of the rotating hole 521, and the blade edges of the two blade structures are disposed in axial symmetry), so that the first blade edge side 510 and the second blade edge side 520 can jointly cut ice blocks. In some other embodiments of the present invention, the first blade edge side 510 and the second blade edge side 520 may also be configured as a knife-like structure with a knife edge or other structures.

In the present invention, referring to fig. 7 and 8, the ice discharge opening 10 has a crushed ice discharge side 100, and when the drum 3 is rotated in the first rotational direction a, the rotary ice blade 52 enters the upper space of the ice discharge opening 10 from directly above the crushed ice discharge side 100, and the fixed ice blade 51 is disposed at a position directly above the crushed ice discharge side 100 or in the vicinity of directly above the crushed ice discharge side 100.

In an embodiment of the present invention, the fixed ice blade 51 is disposed at a position near a position right above the crushed ice discharge side 100. As a preferable mode of the present embodiment, as shown in fig. 5, 7 and 8, the fixed ice blade 51 is positioned in the upper space of the ice discharge port 10, when the first blade side 510 of the fixed ice blade 51 is disposed toward the crushed ice discharge side 100; in order to prevent the whole ice entering the drum 3 from being directly discharged from the crushed ice discharge side 100 of the ice discharge port 10, the ice crusher is a fixed ice blade 51 at the lowest end of the ice blade assembly in this embodiment, and the distance dimension L1 between the blade side 510 of the fixed ice blade 51 and the crushed ice discharge side 100 is smaller than the size of the whole ice. According to the preferred embodiment of the present invention, the crushed ice processed by the ice blade assembly can be rapidly discharged from the ice discharge port, so that the formation of lumps in the drum 3 is prevented, and the whole ice cannot be discharged from the crushed ice discharge side 100.

Referring specifically to fig. 7 and 8, in the first rotation direction a, the rear side of the ice discharge opening 10 is an ice crushing discharge side 100, and during the ice crushing process, the rotary drum 3 drives the rotary ice blade 52 to rotate and realize the cutting process of the whole ice together with the fixed ice blade 51, and the crushed ice enters the ice discharge opening 10 from the ice crushing discharge side 100 to be discharged.

According to the above design structure of the present invention, when the drum 3 rotates in the second rotation direction, the side of the rotating ice blade 52 opposite to the second blade edge side 520 directly pushes the whole ice entering the drum 3 from the ice inlet 30 into the ice outlet 10, so as to realize the direct discharge of the whole ice with large size. Specifically, referring to fig. 7 and 8, the ice discharge port 10 has a whole ice discharge side 101, when the rotary drum 3 drives the rotary ice blade 52 to rotate along the second rotation direction, the rotary ice blade 52 enters the upper space of the ice discharge port 10 from the position right above the whole ice discharge side 101 of the ice discharge port 10, and the size of the distance L2 between the side of the fixed ice blade 51 departing from the blade port side 510 and the whole ice discharge side 101 is larger than that of whole ice, so that the whole ice discharge is realized.

In the embodiment shown in fig. 3, 7 and 8, in which the ice discharge opening 10 is a fan-shaped opening, the center of the circle of the fan shape is located at the position of the fixed shaft 2, and the crushed ice discharge side 100 and the whole ice discharge side 101 respectively form two radii of the center angle of the fan shape.

In a preferred embodiment of the present invention, in order to allow the whole ice entered through the ice inlet 30 to be quickly crushed and discharged by the ice blade assembly, the ice inlet 30 is disposed adjacent to the crushed ice discharge side 100 in the first rotational direction a; specifically, as shown in fig. 8 and 9, the projection of the ice inlet 30 onto the bottom base bottom 11 of the base 1 covers the crushed ice discharge side 100 of the ice discharge opening 10. In this embodiment, the whole ice entering from the ice inlet 30 falls near the crushed ice discharge side 100 and is crushed by the ice blade assembly, and the crushed ice can be rapidly discharged from the ice discharge port 10. Of course, it will be appreciated that in other embodiments of the invention, the projection of the ice inlet 30 onto the bottom housing bottom 11 of the housing 1 is only close to the crushed ice discharge side 100 of the ice discharge opening 10 and does not cover the crushed ice discharge side 100 (not shown in the figures). Viewed from another point, in this embodiment, the front side 500 of the ice inlet 30 substantially overlaps in position with the rear side (i.e., the crushed ice discharge side 100) of the ice discharge opening 10 in the first rotational direction a.

In the above preferred embodiment, the front side 500 of the ice inlet 30 is provided as a structure having a cutting function, and its specific structure can be referred to the first blade edge side 510 of the fixed ice blade 51. In particular implementation, the front side 500 of the ice inlet 30 is substantially vertically coincident with the first blade edge 510 of the stationary blade 51. In the present embodiment, the ice shutter 50 has a function of fixing the ice blade while defining the ice inlet 30. Of course, in other embodiments, the ice inlet 30 of the ice inlet baffle 50 may be provided for only ice without the ice cutting function described above.

In other more preferred embodiments, both the front side 500 and the rear side 501 of the ice inlet 30 in the first rotational direction a are provided with a saw-tooth structure. Based on the arrangement, when the rotary drum 3 rotates along the first rotation direction a, the sawtooth structure of the front side 500 has a function of fixing the ice skate blade, and can assist the ice skate blade assembly to cut whole ice into crushed ice; when the drum 3 rotates in the second rotation direction and the whole ice is pushed out from the whole ice discharge side 101 of the ice discharge port 10 by the back side of the rotary ice blade 52, the whole ice may be caught between the rear side 501 and the back side of the rotary ice blade 52, and if the rear side 501 is provided with a saw-tooth structure, it can quickly cut up the caught ice, so that the whole ice discharge process is smooth, and the problem that the whole ice is not smoothly discharged when the drum rotates in the second rotation direction is effectively solved.

Based on the function of fixing the ice blade at the front side 500 of the ice inlet 30 in the embodiment, during the operation of the ice crusher, the rotating ice blade 52 is disposed between the ice inlet baffle 20 and the fixed ice blade 51 at the uppermost layer, i.e. the uppermost layer of the ice blade assembly is the rotating ice blade 51, so that the design can effectively utilize the ice cutting function at the front side 500 of the ice inlet 30.

In practical application of the present invention, an ice storage bin (not shown) for providing large-sized ice cubes is generally disposed above the drum 3, and in practical implementation, an ice-stirring mechanism is disposed on the top of the drum 3 and rotates synchronously with the drum 3 to stir the ice cubes on the top of the drum 3, and specifically, the ice-stirring mechanism is used to stir the ice cubes inside the ice storage bin so as to guide the ice cubes inside the ice storage bin into the ice inlet 30 on the top of the drum 3.

In a specific design, the ice-removing mechanism comprises a plurality of ice-removing pieces, and each ice-removing piece is provided with a fixed part fixed on the rotary drum and a second rotating hole capable of rotating around the fixed shaft 2. Referring to fig. 4, 5, and 6, the ice-removing mechanism in the present embodiment includes two ice-removing pieces, i.e., a first ice-removing piece 61 and a second ice-removing piece 62, and the first ice-removing piece 61 and the second ice-removing piece 62 are respectively provided with fixing

portions

611 and 621; the inner wall of the drum 3 is provided with two grooves 32 opposite to each other, and the two fixing

portions

611 and 621 are respectively embedded in the two grooves 32 to fix the rotating ice blade 52 and the drum 3. The two second rotating holes 610 and 620 of the ice-removing pieces are respectively and rotatably sleeved on the fixed shaft 2, a gasket 71 is arranged between the two ice-removing pieces on the fixed shaft 2, and a gasket 72 is also arranged between the ice-inlet baffle 50 and the ice-removing piece above the ice-inlet baffle. In the embodiment, the specific shape and structure of the two ice stirring pieces are matched with the internal structure of the ice storage box; referring to fig. 6, an end of the first ice-removing piece 61 away from the fixing portion 611 has a pick (not shown) disposed in a tilted manner.

In this embodiment, the rotation of the drum 3 is realized by the power output of the motor 40, and referring to fig. 2, in order to realize the rotation of the drum 3, the peripheral side wall of the drum 3 is provided with a circle of engaging teeth 31, and the power transmission assembly 4 is provided with a direct drive gear 41 which is engaged with the engaging teeth 31 to drive the rotation of the drum 3. In the present embodiment, the engaging teeth 31 are disposed at the lowest edge position of the outer wall of the drum 3, and in other embodiments, the engaging teeth 31 may also be disposed at the middle or other position (not shown) of the outer wall of the drum 3.

In the embodiment, a gear assembly 42 formed by a plurality of gears is further disposed between the motor 40 and the direct drive gear 41, and the motor 40 drives the direct drive gear to rotate through the gear assembly 42. Specifically, the gear assembly 42 in this embodiment includes two first bevel gears 421 and second bevel gears 422 meshed and matched with each other, wherein the first bevel gear 421 is directly driven by the output shaft of the motor 40, and the second bevel gear 422 and the direct drive gear 41 are disposed on the same rotating shaft; when the motor 40 operates, the output shaft of the motor 40 drives the first bevel gear 421 to rotate, the first bevel gear 421 drives the second bevel gear 422 to rotate, the second bevel gear 422 drives the direct drive gear 41 on the same rotating shaft to rotate, and the direct drive gear 41 is matched with the meshing teeth 31 to realize the ice cutting process inside the rotating drum 3.

In other embodiments, the direct drive gear 41 can be directly driven by the motor 40, or the drum 3 can be directly driven by the motor 40 (not shown).

Referring to fig. 1, 2 and 3, the direct drive gear 41 in this embodiment is fixed on the rotation shaft base 80 through a rotation shaft (not labeled in the figures), and the rotation shaft base 80 is provided with a gear housing 81 for enclosing the direct drive gear 41 and the gear assembly 42, so that the ice crusher provided by the present invention has better safety due to the arrangement of the gear housing 81. Referring to fig. 3, a notch 13 for matching the direct drive gear 41 with the meshing teeth 31 is provided between the gear housing 81 and the drum shroud 12. In some implementations, the gear housing 81 and the drum shield 12 may be integrally formed, thereby providing a modular ice crusher of the present invention for ease of installation on other equipment, such as a refrigerator.

It should be noted that in the invention, the transmission of the power of the rotary drum is realized by adopting a motor and a gear, and the change of the direction in the power transmission process is easier to realize, so that the designed ice crusher is better ensured to have a reasonable space structure. In some embodiments of the present invention, the rotation of the drum 3 may also be realized by means of a chain, a conveyor belt, or the like (not shown in the figures).

Referring to fig. 10 and 11, in another embodiment, the ice crusher of the present invention further includes an ice outlet channel 9 located below the ice discharge port 10, and as shown in fig. 12 and 13, the ice outlet channel 9 includes a funnel-shaped ice receiving portion 91 and a duct portion 92 communicating with a lower end of the ice receiving portion 91, a channel inlet 910 abutting against the ice discharge port 10 is formed at a top end of the ice receiving portion 91, and specifically, the channel inlet 910 is formed at one end of the funnel-shaped ice receiving portion 91 with a large opening area. The duct portion 92 of the present invention extends downward from the lower end of the ice receiving portion 91 in a spiral trend, and a channel outlet 920 for discharging ice cubes in the ice discharging channel 9 is provided at an end of the duct portion 92 away from the ice receiving portion 91.

In order to reduce the impact force of the ice cubes discharged from the ice discharge port 10 on the inner wall of the ice outlet channel 9 when entering the ice outlet channel 9, so as to reduce the probability of damage of the ice outlet channel 9 due to impact of the ice cubes and reduce the noise of the ice crusher during ice discharge, the ice crusher of the present invention is configured as follows.

Specifically, referring to fig. 14, the ice receiving portion 91 and the duct portion 92 have a joint position indicated by 900, the spiral trend line S located at the center of the duct portion 92 has a tangent line L at the joint position indicated by 900, the tangent line L intersects with the plane of the channel inlet 910 at the right side of the center O of the channel inlet 910, the right side area is indicated by a first side b, and the tangent line L intersects with the plane of the channel inlet 910 at Lo. To achieve the above-described effect, a projection of the geometric center of gravity H of the ice discharge opening 10 on the plane of the passage entrance 910 falls within the range of the passage entrance 910 and is shifted toward the first side b.

Based on the above arrangement, the relatively safest distance from the channel outlet 920 to the ice crushing opening 10 can reduce the probability that a user or a child carelessly extends a hand into the ice discharge opening 10 through the ice outlet channel 9 to be cut by the ice blade assembly.

In the specific implementation process, as shown in fig. 15, the ice outlet channel 9 includes a first housing 901 and a second housing 902 that are detachable from each other, and two pairs of fitting edges are provided between the first housing 901 and the second housing 902 to form the ice outlet channel 9. As shown in the figures, the pair of assembling edges 9a can be mutually buckled to be connected and fixed, and the pair of assembling edges 9a is realized by a buckle structure arranged on the two assembling edges during buckling assembly, and the specific structure of the buckle can refer to some existing designs and is not specifically unfolded; the fitting side 9b is fitted in the same manner as the fitting side 9 a.
