Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to a smoothie machine. Background Technology

[0002] As people's living standards improve, the demand for smoothie makers in both home and commercial settings is constantly increasing, and the ability to continuously produce smoothies is receiving more and more attention. The development of smoothie makers allows people to enjoy delicious smoothies more conveniently, enriching their dietary choices and bringing new business opportunities to the food industry.

[0003] In the current slush machine market, the conventional technique to ensure smooth ice dispensing is to expose the scraper blade and rollers. This method, to some extent, ensures that the slush flows smoothly from the ice outlet. However, some slush machines are not designed with effective protection for the scraper and rollers, leaving these components directly exposed at the ice outlet. Others simply assemble the ice dispensing structure without considering user safety during operation.

[0004] However, these existing technologies have obvious drawbacks. Because the scraper blade and roller are exposed, users can easily touch the sharp blade and the moving parts of the roller at the ice outlet on the front of the product. This undoubtedly increases the danger during use and cannot guarantee user safety. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a smoothie machine, which has a cylindrical evaporator installed through an extension, a protective seat with a guide port and a back scraper for cutting smoothies, an open trough exposing the feed box and equipped with a protective cover, a feed tray in the receiving cavity holding the raw liquid, and the lower end of the evaporator immersed in it, thus realizing the production of smoothies. The structure is reasonable, the protection is good, and it is convenient for feeding and operation. At the same time, the scraper is located on the back of the guide port to prevent accidents caused by human hand contact.

[0006] This application is achieved through the following technical solution: A smoothie machine includes a housing with a cylindrical evaporator rotatably connected within it, the evaporator being powered to rotate by a drive device. A scraper is provided within the housing to contact and cut an ice layer formed on the surface of the evaporator into smoothie as the evaporator rotates. The upper end of the housing has an outwardly protruding extension, the cylindrical evaporator being rotatably connected to the extension, and a protective seat is provided at the center of the front of the extension. The protective seat has a guide opening for guiding the smoothie downwards, and the scraper is positioned on the back of the guide opening. An open groove is formed at the upper end of the extension, extending into the housing to expose a feed box installed within the housing. A protective cover is provided on the open groove. A receiving cavity is provided at the lower front of the extension, containing a feed tray for holding the raw liquid supplied by the feed tray. The lower end of the cylindrical evaporator is immersed in the raw liquid.

[0007] By adopting the above technical solution, the extension at the upper end of the slush machine casing provides a stable rotating connection structure for the cylindrical evaporator, ensuring its smooth rotation under the action of the drive device. The guide port on the protective seat effectively guides the slush to fall, facilitating collection. The scraper, located on the back of the guide port, cuts the surface ice layer into slush when the cylindrical evaporator rotates. The open slot extends into the casing, exposing the feed box, which is equipped with a protective cover for convenient operation and protection of the feed box. The feed tray, located in the receiving cavity, holds the raw liquid supplied by the feed box, immersing the lower end of the cylindrical evaporator within it, which is conducive to ice formation. The scraper's location on the back of the guide port effectively reduces the occurrence of accidents. The overall structural design is reasonable, enabling safe and efficient completion of the slush production process, improving the practicality and reliability of the slush machine.

[0008] Optionally, the extension is provided with a positioning slope, the scraper is detachably fixed on the positioning slope, and the back of the protective seat is provided with a clearance step adapted to the scraper.

[0009] By adopting the above technical solution, the positioning bevel on the extension facilitates the detachable fixing of the scraper, making scraper installation and removal easy and convenient, and facilitating scraper replacement, maintenance, and cleaning. The protective base allows the scraper to be stably mounted on its back, preventing the scraper blade from being exposed and avoiding accidents. The back of the protective base has a clearance step adapted to the scraper, ensuring normal operation and guaranteeing that the scraper can smoothly cut the surface ice layer into slush when the cylindrical evaporator rotates, thus improving the safety, aesthetics, practicality, and reliability of the slush machine.

[0010] Optionally, the extension is provided with a positioning groove, the lower end of the protective seat is provided with a positioning boss that matches the positioning groove, and the protective seat is provided with fixing bolt holes.

[0011] By adopting the above technical solution, the positioning groove on the extension of the smoothie machine matches the positioning boss at the lower end of the protective seat, enabling precise positioning of the protective seat on the extension and ensuring accurate installation. Simultaneously, the fixing bolt holes on the protective seat facilitate the secure fixing of the protective seat to the extension with bolts, improving the stability and reliability of the protective seat installation. This ensures that the protective seat can stably perform its protective function against the scraper, making the overall structure of the smoothie machine more robust.

[0012] Optionally, the scraper is fixed to the back of the protective seat.

[0013] By adopting the above technical solution, fixing the scraper to the back of the protective seat allows the extension, scraper, and protective seat to form a unified structure, enhancing the connection stability of the three. Simultaneously, this fixing method makes efficient use of the space behind the protective seat, resulting in a more compact internal structure for the smoothie machine, optimizing the overall layout, and improving the machine's performance, reliability, and safety. Furthermore, positioning the scraper on the back of the protective seat ensures it remains in a safe area, preventing accidental contact with the scraper.

[0014] Optionally, the lower guide surface of the guide port is provided with reinforcing ribs.

[0015] By adopting the above technical solution, reinforcing ribs are installed on the back of the lower guide surface of the guide port, which effectively enhances the structural strength and stability of the guide port. During the operation of the smoothie machine, the reinforcing ribs prevent deformation or damage to the guide port, ensuring its long-term normal use. At the same time, a stable guide port can better guide the smoothie to fall, allowing it to smoothly enter the corresponding container, improving the working efficiency and reliability of the smoothie machine, and extending the service life of the equipment.

[0016] Optionally, the length of the scraper and guide port is not less than the width of the cylindrical evaporator.

[0017] By adopting the above technical solution, setting the length of the scraper and guide port to be no less than the width of the cylindrical evaporator ensures that the scraper can comprehensively cut the ice layer formed on the surface of the cylindrical evaporator when it rotates, avoiding situations where the ice layer is not cut through, thus making the production of slush more complete. At the same time, the guide port can completely guide the cut slush to fall, preventing slush from accumulating inside the machine and ensuring that the slush falls smoothly into the designated position, improving the working efficiency of the slush machine and the quality of the slush produced.

[0018] Optionally, the guide port extends out of the edge of the cylindrical evaporator by a length of L, wherein 2mm≦L≦50mm.

[0019] By adopting the above technical solution, the length of the guide port extending beyond the edge of the cylindrical evaporator is controlled within the range of 2mm-50mm, which effectively guides the slush to fall. This length avoids being too short, which would prevent the slush from falling smoothly, reducing splashing and scattering, and ensuring that the slush falls accurately into the collection point; it also prevents being too long, which would waste space and make the equipment too large, resulting in a compact and reasonable structure for the slush machine. This allows for efficient slush production within a limited space, improving the machine's performance and enhancing the user experience and aesthetics.

[0020] Optionally, the sidewall of the open trough is provided with a vertically arranged positioning groove; the positioning groove is adapted to the feeding box.

[0021] By adopting the above technical solution, vertically arranged positioning grooves are set on the side wall of the open trough and adapted to the feeding box, providing precise positioning for the installation of the feeding box. This makes the installation of the feeding box more stable and accurate, avoiding offset or shaking during installation and ensuring the fitting accuracy between the feeding box and other components of the smoothie machine. At the same time, the vertically arranged positioning grooves facilitate the installation and disassembly of the feeding box, making it easier to maintain, clean, or replace the feeding box, thus improving the convenience and reliability of the smoothie machine during use.

[0022] Optionally, the feeding tray has a raw liquid chamber and a collection chamber; the raw liquid chamber is used to hold the raw liquid supplied by the feeding box; the collection chamber is located below the scraper.

[0023] By adopting the above technical solution, the raw liquid chamber on the feeding tray can hold the raw liquid supplied by the feeding box, ensuring that the lower end of the cylindrical evaporator is immersed in the raw liquid, continuously forming an ice layer and providing sufficient raw materials for slush production. The collection chamber is located below the scraper, which can collect condensate on the scraper, as well as melted ice and ice slag, preventing condensate, melted ice, and ice slag from dripping onto other components, affecting the normal operation of the equipment or causing pollution. Furthermore, integrating the raw liquid chamber and the collection chamber onto the feeding tray makes the slush machine structure more compact and makes more rational use of space.

[0024] Optionally, the bottom surface of the collection chamber is inclined, and a leakage hole is provided at the bottom of the collection chamber.

[0025] By adopting the above technical solution, the bottom surface of the collection chamber is sloping and has a drain hole at the bottom. This allows condensate, melted ice, or ice slag dripping from the scraper to collect better at the bottom of the collection chamber. The sloping structure effectively prevents condensate, melted ice, or ice slag from accumulating in the collection chamber. The collected condensate or melted ice can be drained in time through the drain hole, preventing it from overflowing into other areas of the feeding tray and affecting the quality of the raw liquid. It also prevents the accumulation of condensate, melted ice, or ice slag from breeding bacteria, ensuring the hygiene and normal operation of the smoothie machine and extending its service life.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application uses a cylindrical evaporator installed through the shell extension, and a protective seat guide port works with a back scraper to complete the cutting and discharge of ice slush; the open slot exposes the feeding box and is equipped with a protective cover, and the feeding tray in the receiving cavity holds the raw liquid and the lower end of the evaporator is immersed in it, thus realizing the production of ice slush. The structure is compact, has good protection, and is convenient for feeding and operation.

[0027] 2. This application provides a positioning bevel for the scraper to be detachably fixed via an extension, facilitating scraper installation, adjustment, and replacement; the back of the protective seat is equipped with a step to accommodate the scraper, avoiding interference and ensuring stable contact between the scraper and the ice layer on the evaporator, thus improving cutting reliability.

[0028] 3. This application simplifies installation and positioning by fixing the scraper to the back of the protective seat, making the scraper and the protective seat an integral structure, ensuring the relative position of the scraper and the evaporator is stable, and at the same time, the protective seat enhances the structural stability of the scraper during operation and improves the cutting effect.

[0034] Reference Figures 3-4 The extension 11 is provided with a positioning ramp 114, and the scraper 4 is detachably fixed on the positioning ramp 114. The back of the protective seat 111 is provided with a clearance step 1112 that matches the scraper 4. The positioning ramp 114 facilitates the installation and removal of the scraper 4, and makes it easy to replace and maintain the scraper 4. The scraper 4 can be fixed to the positioning ramp 114 with bolts, and the bolt connection method is simple and firm. The clearance step 1112 matches the scraper 4, and the guide opening 1111 and the scraper 4 form a channel that facilitates the smooth flow of ice slush. The side wall of the open groove 112 is provided with a vertically arranged positioning slide 1122; the positioning slide 1122 matches the feeding box 12. The positioning slide 1122 facilitates the installation and positioning of the feeding box 12, so that the feeding box 12 can be accurately installed in the open groove 112. The positioning slide 1122 can be a dovetail groove, which has a good positioning effect, or it can be a T-shaped groove or a U-shaped groove.

[0035] Reference Figure 3 The length of the scraper 4 and the guide orifice 1111 is not less than the width of the cylindrical evaporator 2. This ensures that the scraper 4 can completely cut the ice layer on the surface of the cylindrical evaporator 2, and the guide orifice 1111 can completely guide the shaved ice to fall, improving the quality of the shaved ice production. The guide orifice 1111 extends beyond the edge of the cylindrical evaporator 2 by a length L, where 2mm≦L≦50mm. This length range can effectively guide the shaved ice to fall, preventing shaved ice accumulation and blockage.

[0036] Reference Figure 4 The extension 11 is provided with a positioning groove 115, and the lower end of the protective seat 111 is provided with a positioning boss 1113 that matches the positioning groove 115. The protective seat 111 is also provided with fixing bolt holes 1114. The cooperation between the positioning groove 115 and the positioning boss 1113 allows the protective seat 111 to be accurately installed on the extension 11, improving installation accuracy. The protective seat 111 is fixed to the extension 11 by bolts passing through the fixing bolt holes 1114, ensuring the stability of the protective seat 111.

[0037] Reference Figures 5-7 The scraper 4 is fixed to the back of the protective base 111. By adopting this arrangement, the scraper 4 can be placed in a safe area that is out of reach of human hands, thus reducing the occurrence of accidents.

[0038] Reference Figure 6 The guide port 1111 has a reinforcing rib 1115 on the back of its lower guide surface. The reinforcing rib 1115 can enhance the structural strength of the guide port 1111 and effectively prevent the guide port 1111 from deforming. The reinforcing rib 1115 can be strip-shaped or mesh-shaped, and its material can be the same as that of the protective seat 111.

[0039] Reference Figure 8 The feeding tray 1131 has a raw liquid chamber 1132 and a collection chamber 1133. The raw liquid chamber 1132 is used to hold the raw liquid supplied by the feeding box 12. The collection chamber 1133 is located below the scraper 4 and is used to collect condensate, melted ice, or ice slag on the scraper 4. The arrangement of the raw liquid chamber 1132 and the collection chamber 1133 makes the feeding tray 1131 more functional, as it can hold raw liquid and collect condensate, melted ice, or ice slag. The bottom surface of the collection chamber 1133 has a sloping structure 1134, and a drain hole 1135 is provided at the bottom of the collection chamber 1133. The sloping structure 1134 allows condensate, melted ice, or ice slag to flow smoothly to the drain hole 1135, which can be connected to a pipe to discharge condensate, melted ice, or ice slag to the outside.

[0040] The implementation principle of this embodiment is as follows: During the slushie making process, the drive device 3 drives the cylindrical evaporator 2 to rotate. Since the lower end of the cylindrical evaporator 2 is immersed in the raw liquid in the feed tray 1131, the beverage or other raw liquid will form an ice layer upon contact with its surface. The scraper 4 abuts against the ice layer on the surface of the cylindrical evaporator 2. As the cylindrical evaporator 2 rotates, the scraper 4 cuts the ice layer into slushie, which falls through the guide port 1111. The feed box 12 continuously supplies raw liquid to the feed tray 1131 to ensure a sufficient supply of raw liquid. At the same time, the scraper 4 is installed on the back of the protective seat 111, which further ensures that the scraper 4 is placed in a place that is out of reach of human hands, effectively improving safety performance.

[0041] Example 2 Reference Figures 9-10The difference between this embodiment and Embodiment 1 is that the magnetic suction device 1116 fixes the protective seat 111 to the extension 11, and the protective seat 111 is fixed to the front of the scraper 4. The magnetic suction device 1116 is located on the back of the protective seat 111. The magnetic suction device 1116 has a strong adsorption force, which can ensure the stable fixation of the protective seat 111 and facilitate disassembly and cleaning. In addition, at least one Hall element 116 can be added to the extension 11 and cooperate with the magnetic suction device 1116 to sense whether the protective seat 111 is installed in the correct position. If it is not installed in the correct position, the Hall element 116 feeds back to the control system of the equipment to stop the operation and prevent the danger caused by the protective seat 111 not being installed in the correct position.

[0042] The implementation principle of this embodiment is as follows: Compared with bolt fixing, the magnetic suction device 1116 for fixing the protective seat 111 has the advantage of convenient installation and disassembly. When it is necessary to replace or clean the protective seat 111, there is no need to use tools to tighten the bolts; simply separating the magnetic suction device 1116 is sufficient to complete the operation, saving time and manpower. At the same time, the magnetic suction force of the magnetic suction device 1116 is uniform and stable, avoiding the installation tilting problem of the protective seat 111 caused by inconsistent tightening that may occur with bolt fixing. The magnetic suction device 1116 fixing method also reduces vibration and instability caused by loose bolts, making the shaved ice making process smoother and without abnormal noise. Furthermore, the use of a Hall element 116 further enhances safety.
