Description

Technical Field

[0001] This utility model relates to the field of frozen beverage machine technology, specifically a frozen beverage machine with stirring blades. Background Technology

[0002] Chinese patent application CN202410556762.3 discloses a condensation structure and a slush machine for a cold drink device. Its drive motor drives a scraper to rotate on the side wall of an evaporator. The evaporator is located in a solution chamber. After liquid is poured in, the evaporator freezes the liquid. Subsequently, the drive motor drives the scraper to rotate on the surface of the evaporator to stir the ice crystal mixture formed on the evaporator surface, thereby forming slush. However, a single scraper can only stir and rotate the ice crystal mixture, but cannot grind it. This results in large ice crystal particles, affecting the texture of the slush. Moreover, if the condensation time in the evaporator is long, a large amount of the un-ground ice crystal mixture will condense into ice blocks. The formation of ice blocks not only causes blockage of the slush outlet but also damages the stirring scraper, leading to blade breakage. Therefore, further improvements are necessary. Utility Model Content

[0003] The present invention aims to provide a frozen beverage machine with a stirring blade to overcome the shortcomings of the prior art.

[0004] A frozen beverage machine with stirring blades designed for this purpose includes a material tank, an evaporator, a drive motor, and stirring blades. The evaporator is disposed inside the material tank, the drive motor is disposed on the evaporator, and the stirring blades are sleeved on the evaporator and driven and connected to the drive motor. The stirring blades rotate and stir the material tank under the drive of the drive motor. The material tank or the evaporator is provided with a stirring part, and the rotating stirring blades and the stirring part open and close alternately.

[0005] The bushing is provided at the front end of the stirring blade, and the stirring blade is driven and connected to the drive motor through the bushing. A stirring plate extends from the side of the bushing, and the stirring part corresponds to the stirring plate.

[0006] The mixing part is an integrally formed protruding part on the inner wall of the material barrel, and the material barrel mixing part is located in front of the stirring plate.

[0007] Alternatively, the stirring part is an integrally formed evaporator stirring part protruding from the front end of the evaporator, and the evaporator stirring part is located behind the stirring plate.

[0008] The front or rear end of the stirring blade extends radially linearly with the bushing as the axis, and the mixing part of the material bucket or the mixing part of the evaporator extends radially linearly with the axis of rotation of the stirring blade as the center.

[0009] The stirring blades and the mixing part of the material bucket or the mixing part of the evaporator are arranged in a planar or concave-convex alternating manner.

[0010] The front or rear end of the stirring blade is flush with the front end, and the end of the mixing part of the material bucket or the mixing part of the evaporator is flush with the front end, so as to achieve a planar staggered opening and closing between the stirring blade and the mixing part of the material bucket or the mixing part of the evaporator.

[0011] The front or rear end of the stirring blade is flush with the ground and also has a protrusion. A step is formed between the front or rear end of the stirring blade and the protrusion. The end of the mixing part of the material tank or the mixing part of the evaporator is flush with the ground and is mutually dependent or spaced out with the step. The side of the mixing part of the material tank or the mixing part of the evaporator is mutually dependent or spaced out with the side of the protrusion, so as to realize the concave-convex staggered opening and closing of the stirring blade and the mixing part of the material tank or the mixing part of the evaporator.

[0012] The end face of the stirring plate, and / or the end face of the mixing part of the material bucket or the mixing part of the evaporator are inclined or angular.

[0013] A collar is provided at the rear end of the stirring blade, and a spiral blade is provided between the stirring blade and the collar.

[0014] The drive motor is located at the rear end of the evaporator, and its power output end is driven to connect to a drive shaft. The drive shaft rotates on the evaporator, and the end of the drive shaft passes through the evaporator and is driven to connect to the bushing.

[0015] This invention features a rotatable stirring blade that, together with a mixing part fixed to the material tank or evaporator, creates a staggered opening and closing motion. This allows the ice crystal mixture on the evaporator to be stirred and pushed by the stirring blade. Simultaneously, the opening and closing stirring blade and mixing part further shear and grind the ice crystal mixture. This not only makes the stirring of the ice crystal mixture more refined, ensuring smaller particle sizes and ultimately improving the texture of the slush, but also effectively prevents the ice crystal mixture from condensing and clumping, thus avoiding blockage at the material tank outlet. Furthermore, the small particle size of the ice crystal mixture does not affect the rotation of the stirring blade, ensuring stable rotation and preventing breakage or damage. The design is stable in operation and has a long service life. Attached Figure Description

[0028] 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.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0030] See Figures 1-7This frozen beverage machine with stirring blades includes a material tank 1, an evaporator 2, a drive motor 3, and stirring blades 4. The evaporator 2 is installed inside the material tank 1, the drive motor 3 is installed on the evaporator 2, and the stirring blades 4 are sleeved on the evaporator 2 and driven and connected to the drive motor 3. The stirring blades 4 rotate and stir inside the material tank 1 under the drive of the drive motor 3. The material tank 1 or the evaporator 2 is provided with a stirring part, and the rotating stirring blades 4 and the stirring part open and close alternately.

[0031] In this embodiment, the rotatable stirring blade 4 and the stirring part fixed on the material tank 1 or evaporator 2 form an alternating opening and closing movement. This allows the ice crystal mixture on the evaporator 2 to be stirred and pushed by the stirring blade 4. At the same time, the opening and closing stirring blade 4 and the stirring part can further shear and grind the ice crystal mixture. This not only makes the stirring of the ice crystal mixture more delicate and ensures that the particle size of the ice crystal mixture is smaller, thereby improving the taste of the shaved ice, but also effectively avoids the problem of the ice crystal mixture condensing and clumping, causing the material tank 1 to be blocked. At the same time, the small particle size of the ice crystal mixture will not affect the rotation of the stirring blade 4, thereby ensuring that the stirring blade 4 can achieve stable rotation and stirring without breaking or being damaged. It is stable in operation and has a long service life.

[0032] A bushing 6 is provided at the front end of the stirring blade 4. The stirring blade 4 is driven and connected to the drive motor 3 through the bushing 6. A stirring plate 8 extends from the side of the bushing 6, and the stirring part corresponds to the stirring plate 8.

[0033] In this embodiment, the mixing part is an integrally formed mixing part 18 protruding from the inner wall of the mixing tank 1, and the mixing part 18 is located in front of the stirring plate 8. The front end of the stirring plate 8 extends radially linearly with the bushing 6 as the axis.

[0034] The mixing section 18 of the material tank extends radially linearly with the axis of rotation of the mixing blade 4 as the center.

[0035] The drive motor 3 is located at the rear end of the evaporator 2, and its power output end is connected to the drive shaft 17. The drive shaft 17 rotates on the evaporator 2. The end of the drive shaft 17 passes through the evaporator 2 and is connected to the bushing 6. The drive shaft 17 avoids the material bucket stirring part 18.

[0036] In this embodiment, when the drive motor 3 is working, it drives the stirring blade 4 to rotate and stir in the material bucket 1 through the cooperation of the drive shaft 17 and the bushing 6. Since the drive shaft 17 and the stirring part 18 of the material bucket avoid each other, the drive shaft 17 will not affect the stirring part 18 of the material bucket when it rotates. The stationary stirring part 18 of the material bucket and the rotating stirring blade 4 can realize the back-to-back alternating opening and closing activities, and can effectively shear and grind the ice slush when the alternating opening and closing is performed.

[0037] Specifically, there are two mixing sections 18 and two stirring blades 8. The two mixing sections 18 extend radially and form a straight line, and the front ends of the two stirring blades 8 also extend radially and form a straight line, so that the two mixing sections 18 and the two stirring blades 8 correspond to each other, so as to effectively shear and grind the ice slush.

[0038] The mixing blade 8 and the mixing part 18 of the material bucket are planar and staggered.

[0039] That is, the front end of the stirring blade 8 and the end of the mixing part 18 of the material bucket are respectively flush, and the front end of the stirring blade 8 and the end of the mixing part 18 of the material bucket rely on each other or cooperate with each other at intervals, so as to realize the planar staggered opening and closing between the mixing part 18 of the material bucket and the stirring blade 8.

[0040] In this application example, the length of the mixing part 18 of the material bucket corresponds to the length of the stirring blade 8 and the two are infinitely close to each other, so as to reduce the gap between the mixing part 18 of the material bucket and the stirring blade 8, thereby enabling the mixing part 18 of the material bucket and the stirring blade 8 to achieve a planar back-to-back staggered opening and closing activity with a small gap, ensuring effective shearing and grinding of the ice slush.

[0041] In addition, the mixing blade 8 and the mixing part 18 of the material bucket have a concave-convex staggered opening and closing mechanism.

[0042] That is, the front end of the stirring blade 8 is flush with the surface and has a protrusion 13. The front end of the protrusion 13 is in contact with or spaced out from the inner wall of the bucket 1, and a step is formed between the protrusion 13 and the front end of the stirring blade 8. The end of the bucket mixing part 18 is flush with the surface and is in contact with or spaced out from the step. The side of the bucket mixing part 18 is in contact with or spaced out from the side of the protrusion 13, so as to realize the concave-convex alternating opening and closing of the bucket mixing part 18 and the stirring blade 8.

[0043] In this application example, the length of the stirring blade 8 is greater than the length of the mixing part 18 of the material bucket, the length of the step corresponds to the length of the mixing part 18 of the material bucket, and the protrusion 13 protrudes from the front end of the stirring blade 8. The front end of the protrusion 13 is infinitely close to the inner wall of the material bucket 1 so that the protrusion 13 can scrape the ice sand from the inner wall of the material bucket 1. In addition, the end of the mixing part 18 of the material bucket and the step, and the side of the mixing part 18 of the material bucket and the side of the protrusion 13 are infinitely close to each other, so that the stirring blade 8 and the mixing part 18 of the material bucket can realize the intermittent back-and-forth opening and closing activities with a small interval, ensuring effective shearing and grinding of the ice sand.

[0044] The end of the mixing section 18 of the material bucket and / or the front end of the mixing blade 8 are inclined or angular.

[0045] In this embodiment, the front end of the stirring blade 8 and the front end of the protrusion 13 are respectively angled in the direction of rotation to effectively stir and push the ice slush. At the same time, the two sides of the end of the mixing part 18 of the material bucket are respectively inclined so that the end of the mixing part 18 of the material bucket forms a mixing blade. The mixing blade and the stirring blade can effectively shear and grind the ice slush.

[0046] The rear end of the stirring plate 8 is either adjacent to or spaced apart from the front end of the evaporator 2.

[0047] In this embodiment, the rear end of the stirring plate 8 is infinitely close to the front end of the evaporator 2, thereby reducing the gap between the rear end of the stirring plate 8 and the front end of the evaporator 2. This prevents the accumulation of ice and sand, while the stirring plate 8 can also effectively scrape off the ice and sand at the front end of the evaporator 2.

[0048] A collar 7 is provided at the rear end of the stirring blade 4, and a spiral blade 9 is provided between the stirring blade 8 and the collar 7.

[0049] In this embodiment, the stirring blade 4 is fitted onto the evaporator 2 through the cooperation of the collar 7 and the spiral blade 9. The spiral blade 9 can stir and push the ice crystal mixture on the evaporator 2. Example

[0050] See Figures 8-12 The difference between this frozen beverage machine with stirring blades and the first embodiment is that the stirring part is an integral evaporator stirring part 19 protruding from the front end of the evaporator 2, and the evaporator stirring part 19 is located behind the stirring blades 8.

[0051] The evaporator stirring section 19 extends radially linearly with the axis of rotation of the stirring blade 4 as the center.

[0052] In this embodiment, two evaporator stirring sections 19 and two stirring blades 8 are provided respectively. The two evaporator stirring sections 19 extend radially linearly and form a straight line. The rear ends of the two stirring blades 8 also extend radially linearly and form a straight line, so that the two evaporator stirring sections 19 and the two stirring blades 8 correspond to each other, so as to shear and grind the ice crystal mixture flowing between the evaporator stirring section 19 and the stirring blades 8.

[0053] The stirring plate 8 and the evaporator stirring part 19 are planar staggered opening and closing.

[0054] That is, the rear end of the stirring plate 8 and the end of the evaporator stirring part 19 are respectively flush, and the rear end of the stirring plate 8 and the end of the evaporator stirring part 19 rely on each other or are spaced apart to achieve planar staggered opening and closing between the stirring plate 8 and the evaporator stirring part 19.

[0055] In this application example, the length of the evaporator stirring section 19 corresponds to the length of the stirring blade 8 and the two are infinitely close to each other, so as to reduce the gap between the stirring blade 8 and the evaporator stirring section 19. This allows the stirring blade 8 and the evaporator stirring section 19 to achieve a planar back-and-forth staggered opening and closing activity with a small gap, ensuring effective shearing and grinding of the ice crystal mixture.

[0056] In addition, the stirring plate 8 and the evaporator stirring part 19 are either flat or have an alternating concave-convex shape.

[0057] That is, the rear end of the stirring plate 8 is flush with the back and has a rear protrusion. The rear protrusion is mutually dependent or spaced with the front end of the evaporator 2, and a step is formed between the rear protrusion and the rear end of the stirring plate 8. The end of the evaporator stirring part 19 is flush with the back and is mutually dependent or spaced with the step. The side of the evaporator stirring part 19 is mutually dependent or spaced with the side of the rear protrusion, so as to realize the concave-convex staggered opening and closing between the stirring plate 8 and the evaporator stirring part 19.

[0058] In this application example, the length of the stirring plate 8 is greater than the length of the evaporator stirring part 19, the length of the step corresponds to the length of the evaporator stirring part 19, and the rear protrusion protrudes from the rear end of the stirring plate 8. The end of the rear protrusion is infinitely close to the front end of the evaporator 2 so that the rear protrusion can scrape off the ice crystal mixture at the front end of the evaporator 2. In addition, the end of the evaporator stirring part 19 and the step, and the side of the evaporator stirring part 19 and the side of the rear protrusion are infinitely close to each other, so that the stirring plate 8 and the evaporator stirring part 19 can achieve a small-interval concave-convex alternating opening and closing activity, ensuring effective shearing and grinding of the ice crystal mixture.

[0059] The end of the evaporator stirring section 19 and / or the rear end of the stirring blades 8 are inclined or angled.

[0060] In this embodiment, the rear end of the stirring blade 8 is angularly oriented towards the direction of rotation to effectively stir and push the ice crystal mixture. Meanwhile, the two sides of the end of the evaporator stirring part 19 are inclined so that the end of the evaporator stirring part 19 forms a stirring blade. The stirring blade and the stirring blade can effectively shear and grind the ice crystal mixture.

[0061] The front end of the stirring blade 8 is flush with the inner wall of the hopper 1, and it is either adjacent to or spaced out from the inner wall of the hopper 1.

[0062] In this application example, the front end of the flush-mounted stirring blade 8 is as close as possible to the inner wall of the equally flush-mounted material container 1 to reduce the gap between them, so that the stirring blade 8 can stir and rotate the ice crystal mixture on the inner wall of the material container 1.

[0063] In addition, the front end of the stirring plate 8 is flush and has a protrusion 13, the front end of the protrusion 13 is either in contact with or spaced out from the inner wall of the material barrel 1.

[0064] In this application example, the inner wall of the material barrel 1 is flush with the inner wall, and the front end of the protrusion 13 is inclined towards the direction of rotation and is infinitely close to the inner wall of the material barrel 1, so that the protrusion 13 can stir and rotate the ice crystal mixture on the inner wall of the material barrel 1.
