Description

Technical Field

[0001] This utility model relates to the field of frozen beverage machine technology, specifically a scraper stirring system and its frozen beverage machine. Background Technology

[0002] Frozen beverage machines, also known as slush machines or ice cream machines, typically include a drive motor, an evaporator, a scraper, and a housing. In use, liquid is poured into the housing, where the evaporator freezes the liquid. The drive motor then drives the scraper to rotate on the surface of the evaporator to stir the mixture of ice crystals formed on the evaporator surface, thus forming slush. The stirring scraper then pushes the slush to the outlet to complete the slush dispensing.

[0003] For example, Chinese utility model patent with patent number CN202422225410.8 discloses a shell structure of a compact snow melting machine; Chinese utility model patent with patent number CN202422198948.4 discloses a household snow melting machine; and Chinese invention application with patent number CN202410556762.3 discloses a condensation structure of a cold drink device and a snow melting machine, etc.

[0004] However, existing frozen beverage machines only have one scraper. A single scraper can only stir and rotate the ice crystal mixture, but cannot grind the ice crystal mixture. This results in large ice crystal particles, affecting the texture of the slush. Moreover, if the evaporator condenses for a long time, a large amount of the ungrindable ice crystal mixture will condense into ice cubes. The appearance of ice cubes not only causes blockage of the slush discharge, but also damages the stirring scraper, causing the scraper blades to break.

[0005] Therefore, further improvements are necessary. Utility Model Content

[0006] The present invention aims to provide a scraper stirring system and its frozen beverage machine to overcome the shortcomings of the prior art.

[0007] A scraper mixing system designed for this purpose includes: A stirring body having a first stirring blade assembly and a spiral scraper assembly capable of rotating about a common axis of rotation; The second stirring plate assembly is rotatably or positionably disposed in the stirring space near the discharge port; The stirring body is rotatably disposed in the stirring space, and the first stirring blade assembly and the second stirring blade assembly move relative to each other during operation.

[0008] The stirring body and the second stirring blade assembly are arranged on the same axis in the stirring space.

[0009] Alternatively, the stirring body and the second stirring blade assembly are arranged on different axes in the stirring space.

[0010] The scraper mixing system also includes a positioning mechanism, which is fixedly arranged relative to the second mixing blade assembly and is used to limit the movement of the second mixing blade assembly within a certain stroke. The first mixing blade assembly and the positioning mechanism perform relative contact or non-contact alternating movements during operation.

[0011] The positioning mechanism is located outside the stirring body and disposed in the stirring space, and the second stirring blade assembly is rotatably disposed at a corresponding position in the stirring space near the outside of the stirring body.

[0012] The positioning mechanism is located inside the stirring body and disposed in the stirring space, and the second stirring blade assembly is rotatably disposed at a corresponding position in the stirring space near the inside of the stirring body.

[0013] The first stirring blade assembly has at least one first stirring blade, the spiral scraper assembly has at least one, and the second stirring blade assembly has at least one second stirring blade, wherein the first stirring blade and the second stirring blade move in a relative contact or non-contact alternating motion during operation.

[0014] The stirring body and the second stirring blade assembly are concentric and can rotate around a common axis of rotation, wherein the first stirring blade and the second stirring blade extend linearly or bendably along the radial direction of the axis of rotation, respectively.

[0015] The stirring body further includes a stirring blade assembly capable of rotating about a common rotation axis with the first stirring blade assembly and the spiral scraper assembly. The stirring blade assembly has at least one stirring blade and is disposed on the spiral scraper assembly or the first stirring blade assembly.

[0016] The stirring body is a single piece.

[0017] The spiral scraper assembly is adapted to plan the frozen mixture along a first rotation direction.

[0018] The stirring blade assembly is adapted to stir the frozen mixture in a second rotation direction that is the same as or opposite to the first rotation direction.

[0019] The first and second stirring blade assemblies are adapted to cut and stir the frozen mixture in a third direction tangential to the first and second rotation directions.

[0020] The mixing space has a first mixing and planing area corresponding to the rotating mixing and planing of the mixing body and a second mixing and cutting area corresponding to the mixing and cutting of the first mixing blade assembly and the second mixing blade assembly. The mixing body and the second mixing blade assembly have relative movements with the cavity wall of the mixing space, either in contact or without contact.

[0021] The stirring body further includes a stirring blade assembly, a collar, and a drive shaft sleeve that are rotatable about a common axis of rotation. The collars are spaced apart along the axis of rotation. The first stirring blade assembly extends linearly to the outside of the collar in the radial direction along the axis of rotation. The spiral scraper assembly is rotatably disposed between the first stirring blade assembly and the collar along the axis of rotation. The stirring blade assembly is rotatably or linearly disposed between the first stirring blade assembly and the spiral scraper assembly, and / or between the spiral scraper assembly and the collar along the axis of rotation.

[0022] The second stirring blade assembly also includes a rotating sleeve, which is rotatable about a common rotation axis on the outside or inside of the drive shaft sleeve, and the second stirring blade extends linearly in the radial direction along the rotation axis on the outside of the rotating sleeve.

[0023] A frozen beverage machine includes the aforementioned scraper stirring system. The frozen beverage machine includes a material tank, an evaporator located inside the material tank, and a drive mechanism disposed on the evaporator. The material tank and the evaporator are installed with a clearance fit, and the gap between them constitutes the stirring space. A first stirring and planing area is formed between the outer periphery of the evaporator and the stirring space. A second stirring and cutting area is formed between the front end of the evaporator and the stirring space. The drive mechanism is drivenly connected to the stirring body.

[0024] This invention utilizes a spiral scraper assembly within a rotating mixing body to stir and push the ice crystal mixture in the mixing space. Simultaneously, the first stirring blade assembly and the rotating or positioned second stirring blade assembly within the mixing body can achieve relative motion during operation. This effectively shears and grinds the ice crystal mixture during the pushing process, resulting in finer stirring and smaller ice crystal particle size, ultimately improving the texture of the smoothie. Furthermore, it effectively prevents the ice crystal mixture from condensing and clumping, reducing blockage at the outlet in the mixing space. Additionally, the small particle size of the ice crystal mixture does not affect the rotation of the mixing body or the relative motion of the first and second stirring blade assemblies, ensuring stable rotation of the mixing body or the second stirring blade assembly, and stable shearing and grinding of the ice crystal mixture by the first and second stirring blade assemblies. This also prevents breakage or damage to the mixing body and the second stirring blade assembly, making the stirring operation more stable and extending its service life. Attached Figure Description

[0043] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0044] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0045] See Figures 1-8 This scraper mixing system includes The stirring body 110 has a first stirring blade assembly 111 and a spiral scraper assembly 112 that are rotatable about a common axis of rotation. The second stirring plate assembly 120 is rotatably or positionably disposed in the stirring space 200 near the discharge port; The stirring body 110 is rotatably disposed in the stirring space 200, and the first stirring blade assembly 111 and the second stirring blade assembly 120 move relative to each other during operation.

[0046] In this embodiment, while the spiral scraper assembly 112 in the rotating stirring body 110 stirs and pushes the ice crystal mixture in the stirring space 200, the first stirring blade assembly 111 and the rotating or positioned second stirring blade assembly 120 in the stirring body 110 can also achieve relative movement during operation. This effectively shears and grinds the ice crystal mixture during the pushing process, which not only makes the stirring of the ice crystal mixture more refined and ensures that the particle size of the ice crystal mixture is smaller, thereby improving the taste of the slush, but also effectively prevents the ice crystal mixture from condensing and clumping, reducing the stirring space 200. The blockage at the outlet of the 00 is eliminated. In addition, the small-sized ice crystal mixture will not affect the rotation of the mixing body 110 or the relative movement of the first mixing blade assembly 111 and the second mixing blade assembly 120. This ensures that the mixing body 110 or the second mixing blade assembly 120 can achieve stable rotation and that the first mixing blade assembly 111 and the second mixing blade assembly 120 can achieve stable shearing and grinding of the ice crystal mixture. Furthermore, it will not cause the mixing body 110 and the second mixing blade assembly 120 to break or be damaged, making the mixing operation more stable and the service life longer.

[0047] The aforementioned scraper mixing system can be applied to a frozen beverage machine, which includes a material tank 300, an evaporator 400 located inside the material tank 300, and a drive mechanism 500 mounted on the evaporator 400. The material tank 300 and the evaporator 400 are fitted together with a gap, and the gap between them forms a mixing space 200. A first mixing and planing area 210 is formed between the outer periphery of the evaporator 400 and the mixing space 200, and a second mixing and cutting area 220 is formed between the front end of the evaporator 400 and the mixing space 200. The drive mechanism 500 is drivenly connected to the mixing body 110.

[0048] In this embodiment, the stirring space 200 is a specific gap area formed after the components are assembled in the frozen beverage machine, used to contain and stir the ice crystal mixture (such as frozen beverage ingredients). The stirring space 200 is not a fixed container, but is dynamically formed mainly by the gap between the material tank 300 and the evaporator 400. In addition, the stirring space 200 is closed or semi-closed, and its boundary is defined by the inner wall of the material tank 300 and the outer wall of the evaporator 400.

[0049] In this embodiment, a sealing plate is provided at the rear end of the evaporator 400, and the drive mechanism 500 is provided on the sealing plate at the rear end of the evaporator 400. The drive shaft 510 is driven to rotate on the evaporator 400 by the drive mechanism 500. The end of the drive shaft 510 passes through the evaporator 400 and is driven to connect with the stirring body 110.

[0050] The front end of the material tank 300 is provided with a discharge port, and a discharge drive component is provided on the discharge port. The user can drive the discharge drive component to open or close the discharge port. The rear end of the material tank 300 is provided with an open opening, through which the evaporator 400 is placed inside the material tank 300. The sealing plate at the rear end of the evaporator 400 is sealed to the open opening, so that the gap between the inner wall of the material tank 300, the outer wall of the evaporator 400, and the inner wall of the sealing plate forms a stirring space 200.

[0051] The mixing space 200 has a first mixing and planing area 210 corresponding to the rotating mixing and planing of the mixing body 110 and a second mixing and cutting area 220 corresponding to the mixing and cutting of the first mixing blade assembly 111 and the second mixing blade assembly 120.

[0052] Specifically, since the outer periphery of the evaporator 400 is spaced apart from the inner wall of the material tank 300, a first stirring and planing area 210 is formed between the outer periphery of the evaporator 400 and the stirring space 200, and a second stirring and cutting area 220 is formed between the front end of the evaporator 400 and the stirring space 200.

[0053] The stirring body 110 also includes a stirring blade assembly 113, a collar 114, and a drive shaft sleeve 115 that are rotatable about a common rotation axis. The collars 114 are spaced apart along the rotation axis, the first stirring blade assembly 111 extends linearly in the radial direction along the rotation axis outside the collar 114, and the spiral scraper assembly 112 is rotatably disposed between the first stirring blade assembly 111 and the collar 114 along the rotation axis.

[0054] The stirring blade assembly 113 has at least one stirring blade and is disposed on the spiral scraper assembly 112 or the first stirring blade assembly 111.

[0055] Furthermore, the stirring blade assembly 113 is linearly disposed between the first stirring blade assembly 111 and the spiral scraper assembly 112, and / or between the spiral scraper assembly 112 and the collar 114, along the extension direction of the rotation axis.

[0056] When the stirring body 110 is assembled, it can be sleeved on the outer periphery of the evaporator 400 by the spiral scraper assembly 112 and the stirring blade assembly 113, and positioned on the front side of the sealing plate by the collar 114. The first stirring blade assembly 111 is located at the front end of the evaporator 400 after the stirring body 110 is assembled.

[0057] In this embodiment, the stirring body 110 and the second stirring blade assembly 120 are arranged on the same axis in the stirring space 200. That is, the stirring body 110 and the second stirring blade assembly 120 are arranged in the stirring space 200 with the drive shaft 510 as the common axis of rotation.

[0058] In addition, since the second stirring blade assembly 120 can be set in a rotating manner, the stirring body 110 can stir and push the ice crystal mixture when rotating. The ice crystal mixture in the stirring and pushing can drive the second stirring blade assembly 120 to rotate asynchronously relative to the stirring body 110 on the same axis. This allows the first stirring blade assembly 111 and the rotating second stirring blade assembly 120 to achieve relative motion during operation, thereby achieving effective shearing and grinding of the ice crystal mixture in the pushing process.

[0059] In addition, it is conceivable that the second stirring blade assembly 120 can also be positioned, that is, the second stirring blade assembly 120 is fixed in the stirring space 200 with the drive shaft 510 as the axis. Specifically, the material tank 300 or the evaporator 400 is provided with a positioning part for fixing the second stirring blade assembly 120. The second stirring blade assembly 120 can be positioned in the stirring space 200 through the positioning part. Alternatively, the second stirring blade assembly 120 can be integrally formed on the material tank 300 or the evaporator 400. The rotating first stirring blade assembly 111 can move relative to the stationary second stirring blade assembly 120, which can also effectively shear and grind the ice crystal mixture during the pushing process.

[0060] In this embodiment, the stirring body 110 may also be arranged in the stirring space 200 on a non-coaxial axis with the second stirring blade assembly 120.

[0061] That is, the stirring body 110 is arranged in the stirring space 200 with the drive shaft 510 as the axis, and the second stirring blade assembly 120 is rotated in the stirring space 200 with a certain offset position relative to the axis of the drive shaft 510. Similarly, when the stirring body 110 rotates, it can stir and push the ice crystal mixture. The ice crystal mixture in the stirring and pushing can drive the second stirring blade assembly 120 to rotate asynchronously relative to the stirring body 110 with an offset axis. This allows the first stirring blade assembly 111 and the rotating second stirring blade assembly 120 to achieve relative motion during operation, thereby achieving effective shearing and grinding of the ice crystal mixture during the pushing process.

[0062] In addition, it is conceivable that the second stirring blade assembly 120 can also be set by positioning and offsetting the axis, that is, the second stirring blade assembly 120 is fixed in the stirring space 200 with a certain offset position relative to the axis of the drive shaft 510. Specifically, the material tank 300 or the evaporator 400 is provided with a positioning part for fixing the second stirring blade assembly 120. The second stirring blade assembly 120 can be positioned in the stirring space 200 through the positioning part. Alternatively, the second stirring blade assembly 120 can be integrally formed on the material tank 300 or the evaporator 400. The rotating first stirring blade assembly 111 can move relative to the stationary second stirring blade assembly 120, which can also effectively shear and grind the ice crystal mixture during the pushing process.

[0063] Specifically, in this embodiment, it is preferable to adopt a scheme in which the stirring body 110 and the second stirring blade assembly 120 rotate in the stirring space 200 with the drive shaft 510 as the same axis, because this scheme is easy to implement and has good effect.

[0064] That is, the spiral scraper assembly 112 and the stirring blade assembly 113 can stir, plan, and push the ice crystal mixture in the first stirring and planing zone 210 during operation. The first stirring blade assembly 111 and the second stirring blade assembly 120 can stir, shear, and grind the ice crystal mixture in the second stirring and cutting zone 220 during operation.

[0065] The scraper mixing system also includes a positioning mechanism 140, which is fixedly arranged relative to the second mixing blade assembly 120 and is used to limit the movement of the second mixing blade assembly 120 within a certain stroke. The first mixing blade assembly 111 and the positioning mechanism 140 perform relative contact or non-contact alternating movements during operation.

[0066] In this embodiment, the positioning mechanism 140 is located outside the stirring body 110 and is disposed in the stirring space 200, and the second stirring blade assembly 120 is rotatably disposed at a corresponding position in the stirring space 200 near the outside of the stirring body 110.

[0067] The first stirring blade assembly 111 has at least one first stirring blade, the spiral scraper assembly 112 has at least one, and the second stirring blade assembly 120 has at least one second stirring blade, wherein the first stirring blade and the second stirring blade move alternately in contact or non-contact manner during operation.

[0068] The stirring body 110 and the second stirring blade assembly 120 are concentric and can rotate around a common axis of rotation, wherein the first stirring blade and the second stirring blade extend linearly or bendably along the axis of rotation.

[0069] In this embodiment, two first stirring blades are provided, namely, first stirring blade A 111A and first stirring blade B 111B. First stirring blade A 111A and first stirring blade B 111B extend linearly along the rotation axis on the left and right sides of the transmission shaft sleeve 115, that is, first stirring blade A 111A and first stirring blade B 111B are symmetrically positioned on the left and right sides of the transmission shaft sleeve 115 and form a straight line with each other. Alternatively, it is conceivable that first stirring blade A 111A and first stirring blade B 111B can also extend in an S-shape along the rotation axis on the left and right sides of the transmission shaft sleeve 115.

[0070] Two spiral scraper assemblies 112 are also provided, and are respectively rotatably disposed between the first stirring blade 111A and the collar 114 along the rotation axis, and between the first stirring blade 111B and the collar 114.

[0071] There are two stirring blade assemblies 113, namely stirring blade A 113A and stirring blade B 113B. Stirring blade A 113A is linearly arranged between the first stirring blade assembly 111 and the spiral scraper assembly 112 along the extension direction of the rotation axis, and stirring blade B 113B is linearly arranged between the spiral scraper assembly 112 and the collar 114 along the extension direction of the rotation axis.

[0072] In addition, stirring blade A 113A and stirring blade B 113B extend on the same linear segment. Alternatively, it can be analogous that stirring blade A 113A and stirring blade B 113B can also extend on different linear segments, i.e., stirring blade A 113A and stirring blade B 113B extend in a staggered linear manner.

[0073] The mixing body 110 is integrally formed. That is, the first mixing blade A 111A, the first mixing blade B 111B, the two spiral scraper assemblies 112, the mixing blade A 113A, the mixing blade B 113B, and the collar 114 are all integrally formed. In this embodiment, the mixing body 110 is preferably made of plastic.

[0074] The second stirring blade assembly 120 also includes a rotating sleeve 122, which is rotatable about a common axis of rotation outside the drive shaft sleeve 115.

[0075] There are two second stirring blades, designated as A second stirring blade 121A and B second stirring blade 121B. A second stirring blade 121A and B second stirring blade 121B extend linearly along the rotation axis on the left and right sides of the rotating sleeve 122, that is, A second stirring blade 121A and B second stirring blade 121B are symmetrically positioned on the left and right sides of the rotating sleeve 122 and form a straight line with each other. Alternatively, it is conceivable that A second stirring blade 121A and B second stirring blade 121B can also extend in an S-shape along the rotation axis on the left and right sides of the rotating sleeve 122.

[0076] In this embodiment, the second stirring blade assembly 120 is integrally formed. That is, the drive shaft sleeve 115, the second stirring blade A 121A, and the second stirring blade B 121B are all integrally molded. In this embodiment, the second stirring blade assembly 120 is preferably integrally formed using plastic.

[0077] The spiral scraper assembly 112 is adapted to plan the frozen mixture along a first rotation direction.

[0078] The stirring blade assembly 113 is adapted to stir the frozen mixture in a second rotational direction that is the same as the first rotational direction. In addition, it is conceivable that the stirring blade assembly 113 can also be adapted to stir the frozen mixture in a second rotational direction that is opposite to the first rotational direction.

[0079] The first stirring blade assembly 111 and the second stirring blade assembly 120 are adapted to cut and stir the frozen mixture in a third direction tangent to the first rotation direction and the second rotation direction.

[0080] Specifically, the drive mechanism 500 is a drive motor, the end of which of its drive shaft 510 passes through the evaporator 400 and is driven connected to the transmission shaft sleeve 115. The drive shaft 510 and the rotating sleeve 122 avoid each other.

[0081] When the drive mechanism 500 is working, it drives the spiral scraper assembly 112 to plane the frozen mixture in the first rotation direction (clockwise) through the drive shaft 510. The stirring blade assembly 113 stirs the frozen mixture in the same second rotation direction (clockwise) as the first rotation direction. The first stirring blade assembly 111 and the second stirring blade assembly 120 cut and stir the frozen mixture in a third direction (perpendicular to the clockwise direction) that is tangent to the first rotation direction and the second rotation direction.

[0082] When the stirring body 110 and the second stirring blade assembly 120 rotate, they undergo relative motion with the stirring space 200 cavity wall in either contact or non-contact manner.

[0083] The outer periphery of the spiral scraper assembly 112 is infinitely close to, but not in contact with, the outer peripheral wall of the mixing space 200, and there is a non-contact relative motion between the spiral scraper assembly 112 and the mixing space 200. The outer periphery of the stirring blade assembly 113 is spaced apart from the outer peripheral wall of the mixing space 200, and there is a non-contact relative motion between the two.

[0084] In this embodiment, the positioning mechanism 140 protrudes from the inner front wall of the material barrel 300 and is located on the outer front side of the stirring body 110. The front end of the second stirring blade assembly 120 is mutually dependent or spaced out from the inner front wall of the material barrel 300. When the second stirring blade assembly 120 rotates to a certain position, it is positioned on the positioning mechanism 140. This ensures that the second stirring blade assembly 120 can be positioned and avoids the problem of easy breakage and damage due to rigid assembly of the second stirring blade assembly 120. At this time, the continuously rotating first stirring blade assembly 111 and the second stirring blade assembly 120 make relative contact and interlacing movements. In addition, the continuously rotating first stirring blade assembly 111 also makes relative contact and interlacing movements with the positioning mechanism 140, thereby effectively shearing and grinding the ice crystal mixture during the pushing process.

[0085] In this embodiment, a front positioning piece 130 is provided on the outer side of the front end of the transmission shaft sleeve 115, and a front limiting distance is formed between the front positioning piece 130 and the transmission shaft sleeve 115. The second stirring piece assembly 120 rotates freely on the front limiting distance through the rotating sleeve 122.

[0086] In this embodiment, the front positioning plate 130 is fixed to the front end of the transmission shaft sleeve 115 by fasteners, and the two form a front limit gap after being fixed together. The second stirring plate assembly 120 can rotate freely on the front limit gap by using the rotating sleeve 122.

[0087] The first stirring blade assembly 111 and the second stirring blade assembly 120 are either planar or staggered in a concave-convex manner.

[0088] In this embodiment, the front end of the first stirring blade assembly 111 is flush with the front end, and the rear end of the second stirring blade assembly 120 is either adjacent to or spaced apart from the front end of the first stirring blade assembly 111.

[0089] That is, the length of the second stirring blade assembly 120 corresponds to the length of the first stirring blade assembly 111, and the two are infinitely close but not in contact, so as to reduce the gap between the first stirring blade assembly 111 and the second stirring blade assembly 120. Thus, the first stirring blade assembly 111 and the second stirring blade assembly 120 can achieve a planar back-to-back staggered opening and closing activity with a small gap, ensuring effective shearing and grinding of the ice crystal mixture.

[0090] The front and / or rear ends of the first stirring plate assembly 111 and the front and / or rear ends of the second stirring plate assembly 120 are inclined or angular.

[0091] In this embodiment, the first stirring blade assembly 111 and the second stirring blade assembly 120 are respectively inclined to effectively guide, stir, push, shear, and grind the ice crystal mixture. Example

[0092] See Figures 9-12The difference between this scraper stirring system and its frozen beverage machine and the first embodiment is that: The stirring blade assembly 113 is rotatably disposed between the first stirring blade assembly 111 and the spiral scraper assembly 112, and / or between the spiral scraper assembly 112 and the collar 114, along the rotation axis.

[0093] Specifically, there are two stirring blade assemblies 113, namely stirring blade A 113A and stirring blade B 113B. Stirring blade A 113A is rotatably disposed between the first stirring blade assembly 111 and the spiral scraper assembly 112 along the extension direction of the rotation axis, and stirring blade B 113B is rotatably disposed between the spiral scraper assembly 112 and the collar 114 along the extension direction of the rotation axis.

[0094] In addition, stirring blade A 113A and stirring blade B 113B extend along the same rotational line segment. Alternatively, it can be analogous that stirring blade A 113A and stirring blade B 113B can also extend along different rotational line segments, that is, stirring blade A 113A and stirring blade B 113B extend and rotate in a staggered manner. Example

[0095] See Figures 13-18 The difference between this scraper stirring system and its frozen beverage machine and the first embodiment is that: The second stirring blade assembly 120 also includes a rotating sleeve 122, which is rotatable about a common axis of rotation inside the drive shaft sleeve 115.

[0096] The positioning mechanism 140 is located inside the stirring body 110 and is disposed in the stirring space 200. The second stirring blade assembly 120 is rotatably disposed at a corresponding position in the stirring space 200 near the inside of the stirring body 110.

[0097] Specifically, a rear positioning plate 150 is provided on the inner side of the rear end of the transmission shaft sleeve 115, and a rear limiting distance is formed between the rear positioning plate 150 and the transmission shaft sleeve 115. The second stirring plate assembly 120 rotates freely on the rear limiting distance through the rotating sleeve 122.

[0098] In this embodiment, the rear positioning plate 150 is fixed to the rear end of the transmission shaft sleeve 115 by fasteners, and the two form a rear limiting distance after being fixed together. The second stirring plate assembly 120 can be freely rotated on the rear limiting distance by the rotating sleeve 122.

[0099] The front end of the evaporator 400 is provided with a positioning mechanism 140. The rear end of the second stirring plate assembly 120 is mutually dependent or spaced with the front end of the evaporator 400 and is positioned on the positioning mechanism 140 when it rotates to a certain position. The front end of the first stirring plate assembly 111 is mutually dependent or spaced with the inner wall of the material tank 300.

[0100] In this embodiment, the positioning mechanism 140 protrudes from the front end of the evaporator 400. Since the second stirring blade assembly 120 can rotate freely on the rear limit distance, the first stirring blade assembly 111 can rotate or the ice crystal mixture can be stirred, thus driving the second stirring blade assembly 120 to rotate together. When the second stirring blade assembly 120 rotates at a certain angle, it is positioned on the positioning mechanism 140. In this way, it can ensure that the second stirring blade assembly 120 can be positioned, and avoid the problem that the rigid assembly of the second stirring blade assembly 120 is prone to breakage and damage.

[0101] Furthermore, the rear end of the second stirring plate assembly 120 is infinitely close to the front end of the evaporator 400, but the two are not in contact, thereby reducing the gap between the rear end of the second stirring plate assembly 120 and the front end of the evaporator 400 and preventing the accumulation of ice crystal mixture. The front end of the first stirring plate assembly 111 is infinitely close to the inner front wall of the material tank 300, but the two are not in contact, so that the first stirring plate assembly 111 can effectively scrape the ice crystal mixture on the inner front wall of the material tank 300.

[0102] The rear end of the first stirring blade assembly 111 is flush with the rear end, and the front end of the second stirring blade assembly 120 is either adjacent to or spaced apart from the rear end of the first stirring blade assembly 111.

[0103] That is, the length of the second stirring blade assembly 120 corresponds to the length of the first stirring blade assembly 111, and the two are infinitely close but not in contact, so as to reduce the gap between the first stirring blade assembly 111 and the second stirring blade assembly 120. Thus, the first stirring blade assembly 111 and the second stirring blade assembly 120 can achieve a planar back-to-back staggered opening and closing activity with a small gap, ensuring effective shearing and grinding of the ice crystal mixture.

[0104] Other undescribed parts are the same as in the first embodiment.
