Description
Technical Field
[0001] This utility model relates to the field of electrical technology, specifically to a smoothie machine. Background Technology
[0002] As a commonly used piece of equipment in the food processing industry, the mixing blades of a smoothie machine are its core working component, responsible for mixing and crushing ingredients to form a uniform and smooth smoothie. However, in existing designs, the lack of a limiting structure at the front end of the blades makes them prone to friction with the inner wall of the mixing drum during high-speed operation. This not only causes scratches on the drum surface but may also affect the hygiene, safety, and lifespan of the product. Therefore, optimizing the clearance between the mixing blades and the mixing drum to effectively prevent abnormal friction has become an important technical challenge for improving the operational reliability of smoothie machines.
[0003] Currently, the fan in slush machines is installed inside the condenser, using a suction design. The cold air flow path is as follows: outside cold air first undergoes heat exchange through the condenser, then enters the machine body to cool the compressor, and finally is exhausted from both sides of the machine body. However, this design has obvious drawbacks: on the one hand, the condenser's heat dissipation efficiency is insufficient; on the other hand, the air heated by the condenser then cools the compressor, resulting in poor overall temperature control, which in turn seriously affects the slush machine's ice-making efficiency and slush quality. Utility Model Content
[0004] The purpose of this invention is to provide a smoothie machine with a protrusion at the top of the mixing blade to prevent the mixing blade from contacting the material cylinder and causing scratches.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A smoothie machine includes a casing, a material cylinder, an evaporator, a stirring blade, and a motor. The material cylinder is disposed on the casing, and the evaporator is disposed inside the material cylinder. The motor drives the stirring blade to rotate, and the stirring blade is disposed around the evaporator. A protrusion is provided at the end of the stirring blade away from the motor. A planetary gear is connected to the output end of the motor, and a drive shaft is fixedly connected to the end of the planetary gear away from the motor. The end of the drive shaft away from the planetary gear is connected to the stirring blade.
[0007] Preferably, the protrusion is annular, and the protrusion and the stirring blade are integrally formed.
[0008] Preferably, the drive shaft is connected to the planetary gear screw; the drive shaft is also connected to the agitator blade key.
[0009] Preferably, the evaporator includes a refrigeration tank, on which a press-fit nut is provided, and on which a temperature probe is provided.
[0010] Preferably, a sealing ring is provided between the press-fit nut and the refrigeration barrel.
[0011] Preferably, the housing is equipped with a compressor, a condenser and a fan. Air inlets are provided on both sides of the housing. The fan is located between the condenser and the compressor. The fan generates negative pressure to draw air into the housing through the air inlets and then through the compressor, the fan and the condenser in sequence, and finally discharges it outside the housing.
[0012] Preferably, the bottom of the housing is a chassis, and bolts are provided on the chassis, with the bolts and the chassis being an integrally formed structure.
[0013] Compared with the prior art, the smoothie machine of this application has the following advantages:
[0014] 1. This application provides a protrusion at the end of the mixing blade away from the motor, which creates a partition between the front end of the mixing blade and the wall of the material cylinder, greatly reducing the contact area and improving the service life of the product.
[0015] 2. The planetary gear structure increases torque and reduces speed, adapting to the high resistance conditions of ice slush; the drive shaft is directly connected to the stirring fan blades, reducing energy loss and extending motor life.
[0016] 3. The annular protrusion is integrally formed with the stirring fan blade, avoiding stress concentration caused by welding or bolt connection and preventing breakage.
[0017] 4. The planetary gears and drive shaft are connected by screws, which facilitates disassembly and replacement; the drive shaft is fixed by screws, which prevents loosening and deflection, and will not come off, thus increasing stability.
[0018] 5. The temperature probe is fixed to the refrigeration tank by a press-fit nut, which is more convenient than the traditional method of requiring a separate nut to limit the position before the sensor probe can be installed into the tank.
[0019] 6. The fan's placement allows cool air to enter the casing from both sides, prioritizing cooling the compressor, then passing through the fan to cool the condenser, and finally exiting the casing. This improves the overall cooling efficiency and reduces the smoothie forming time by about 10%.
[0020] 7. The bolts are integrally molded with the chassis to enhance overall rigidity and prevent loosening due to transportation or vibration; this also reduces assembly steps and lowers processing costs. Attached Figure Description

[0028] The following detailed description illustrates the specific implementation method:
[0029] The reference numerals in the accompanying drawings include: housing 1, material cylinder 2, evaporator 3, stirring blade 4, motor 5, protrusion 6, planetary gear 7, drive shaft 8, refrigeration tank 9, press-fit nut 10, temperature probe 11, sealing ring 12, compressor 13, condenser 14, fan 15, chassis 16, bolt 17, air inlet 18.
[0030] As attached Figure 1-7 As shown in the figure, this embodiment illustrates a smoothie machine, including a housing 1, a material cylinder 2, an evaporator 3, a stirring blade 4, and a motor 5. The material cylinder 2 is disposed on the housing 1, the evaporator 3 is disposed inside the material cylinder 2, the motor 5 drives the stirring blade 4 to rotate, the stirring blade 4 is disposed around the evaporator 3, and a protrusion 6 is provided at the end of the stirring blade 4 away from the motor 5; a planetary gear 7 is connected to the output end of the motor 5, a drive shaft 8 is fixedly connected to the end of the planetary gear 7 away from the motor 5, and the end of the drive shaft 8 away from the planetary gear 7 is connected to the stirring blade 4.
[0031] Existing blender blades have no limit at the front end, which easily causes friction between the blades and the material cylinder during use, resulting in scratches on the cylinder. In this embodiment, a protrusion 6 is provided at the front end of the stirring blade 4, forming a partition between the front end of the stirring blade 4 and the cylinder wall of the material cylinder 2, preventing the stirring blade 4 from contacting the material cylinder 2 and causing scratches, thereby improving the product's service life.
[0032] The protrusion 6 is annular and is integrally formed with the stirring blade 4. This integral forming avoids stress concentration caused by welding or bolting, preventing breakage. In some embodiments, the protrusion 6 can also be elliptical, triangular, quadrilateral, pentagonal, etc., without limitation.
[0033] The drive shaft 8 is connected to the planetary gear 7 by screws. The drive shaft 8 is fixed with screws, which reduces the risk of loosening or deflection and prevents it from detaching, thus increasing stability. The drive shaft 8 is connected to the agitator blade 4 by a key. The key connection ensures that the blade and drive shaft 8 rotate synchronously and resist torsion; the key connection also reduces radial runout between the drive shaft 8 and the blade, lowering vibration and noise.
[0034] The planetary gear 7 structure in this embodiment increases torque and reduces speed, adapting to the high resistance conditions of the smoothie machine; the drive shaft 8 is directly connected to the stirring fan blade 4, reducing energy loss and extending the life of the motor 5.
[0035] The evaporator 3 includes a refrigeration tank 9, on which a press-fit nut 10 is mounted. A temperature probe 11 is mounted on the press-fit nut 10, and a sealing ring 12 is provided between the press-fit nut 10 and the refrigeration tank 9. The fixing structure of the press-fit nut 10 on the refrigeration tank 9 facilitates the direct external fixing of the temperature probe 11. Compared to existing methods that require a separate nut to be positioned before the sensor probe can be installed into the tank, which is extremely inconvenient, this embodiment integrates the press-fit nut 10 with the cylinder wall. During the installation of the temperature probe 11, there is no need to separately fix the nut, greatly improving installation efficiency and making installation more convenient.
[0036] In some embodiments, a compressor 13, a condenser 14 and a fan 15 are provided inside the housing 1. Air inlets 18 are provided on both sides of the housing 1. The fan 15 is located between the condenser 14 and the compressor 13. The fan 15 generates negative pressure to draw air into the housing 1 from the air inlets 18 and pass through the compressor 13, the fan 15 and the condenser 14 in sequence, and finally discharge it outside the housing 1.
[0037] The existing condenser heat exchanger circulation air system draws air from the rear and exhausts it from both sides. In this embodiment, air is drawn from both sides and exhausted from the rear, which improves the overall cooling efficiency and shortens the shaved ice forming time by about 10%.
[0038] The bottom of the housing 1 is the chassis 16, and bolts 17 are installed on the chassis 16. The bolts 17 and the chassis 16 are integrally formed. The integral forming of the bolts 17 and the chassis 16 enhances the overall rigidity and prevents loosening due to transportation or vibration; it also reduces assembly steps and lowers processing costs. At the same time, the integral forming structure increases friction during the installation of the compressor 13, improving the stability of the equipment.
[0039] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
