Description

Technical Field

[0001] This utility model relates to food vending machines, and in particular to a stirring and cleaning device and a milkshake vending machine. Background Technology

[0002] Some existing milkshake vending machines use a cup storage mechanism to place cups into a cup transfer mechanism, which then moves the cups to the ingredient receiving position. After the ingredients are poured into the cups, the transfer mechanism moves the cups to the mixing mechanism of a mixing and cleaning device. The mixing mechanism stirs and mixes the ingredients in the cups to make a milkshake. The transfer mechanism then ejects the cups from the dispensing port. Afterward, the mixing head of the mixing mechanism is cleaned by the cleaning mechanism of the mixing and cleaning device. In this mixing and cleaning device, the mixing head of the mixing mechanism can move up and down. The cleaning mechanism includes a cleaning cylinder, an annular water-retaining cover, and a water supply assembly. The annular water-retaining cover is detachably installed at the upper end of the cleaning cylinder. The mixing head can pass through the annular water-retaining cover and extend into the cleaning cylinder. The cylinder wall has spray nozzles and drain outlets. The water supply assembly sprays water into the cleaning cylinder through the spray nozzles, working in conjunction with the rotation of the mixing head to clean it. Wastewater is discharged from the drain outlet, and the annular water-retaining cover reduces water splashing. Currently, the above-mentioned mixing and cleaning devices require a high degree of sealing at the connection between the cleaning cylinder and the annular water-retaining cover, resulting in a relatively complex structure and high manufacturing and assembly costs.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Reference Figures 1 to 4 This invention relates to a stirring and cleaning device, comprising a frame 100, a stirring mechanism 200, and a cleaning mechanism 300. The stirring mechanism 200 is mounted on the frame 100 and includes a stirring head 210, a rotation driver 220, and a lifting driver 230. The rotation driver 220 drives the stirring head 210 to rotate along its vertical axis and is movably mounted on the frame 100 in the vertical direction. The lifting driver 230 drives the rotation driver 220 and the stirring head 210 to move vertically. The cleaning mechanism 300 is mounted on the frame 100. 300 includes a cleaning cylinder 310 and a water supply assembly 320. The cleaning cylinder 310 is arranged in the vertical direction. An annular water baffle 311 is integrally formed on the upper periphery of the cleaning cylinder 310. An inlet / outlet hole 312 is formed in the middle of the annular water baffle 311. The inlet / outlet hole 312 is vertically opposite to the stirring head 210. A drain outlet 313 is provided at the lower end of the cleaning cylinder 310. A water spray nozzle 314 is provided on the side wall of the cleaning cylinder 310. The water supply port of the water supply assembly 320 is connected to the water spray nozzle 314.

[0025] When the stirring head 210 needs cleaning, the lifting driver 230 drives the rotating driver 220 and the stirring head 210 to descend. The stirring head 210 passes through the annular water baffle 311 and enters the cleaning cylinder 310 through the inlet and outlet hole 312. Then, the water supply component 320 sprays water onto the stirring head 210 through the spray nozzle 314, and the rotating driver 220 drives the stirring head 210 to rotate to clean the stirring head 210. After cleaning, the stirring head 210 returns to its original position and moves away. Since the annular water baffle 311 is formed by integral molding of the upper periphery of the cleaning cylinder 310, there is no need to assemble or consider assembly sealing, thereby simplifying the assembly process and reducing manufacturing and assembly costs.

[0026] In the embodiments, reference is made to Figure 3 The stirring mechanism 200 also includes a water-blocking structure 240. The rotary driver 220 is configured as a first motor. The first motor includes a motor body 221 and an output shaft 222 rotatably connected to the motor body 221. The output shaft 222 is arranged in the vertical direction. The stirring head 210 is connected to the lower end of the output shaft 222. The water-blocking structure 240 is fixedly arranged relative to the motor body 221. The water-blocking structure 240 is annular and has a through hole. The output shaft 222 passes through the through hole. The water-blocking structure 240 is located above the stirring head 210. The water-blocking structure 240 is vertically opposite to the inlet / outlet hole 312.

[0027] When water splashes out from the inlet / outlet hole 312, the water splashes can be blocked by the water-blocking structure 240, making it less likely for water to splash onto the motor body 221 or other parts of the milkshake vending machine. This prevents water splashes from affecting the first motor, improves the service life and operational stability of the rotary drive 220, and reduces the risk of water splashes contaminating the inside of the milkshake vending machine. Furthermore, the size of the inlet / outlet hole 312 does not need to be too small, reducing the risk of the stirring head 210 colliding with the cleaning cylinder 310 due to insertion accuracy issues during the insertion of the stirring head 210 into the inlet / outlet hole 312, and lowering the insertion accuracy requirements of the stirring head 210 and the cleaning cylinder 310.

[0028] It is conceivable that in other embodiments, the rotary drive 220 could also be, for example, an internal combustion engine.

[0029] In the embodiments, reference is made to Figure 4 The water-blocking structure 240 includes a waterproof sleeve 241 and a water-blocking plate 242. The waterproof sleeve 241 is arranged around the output shaft 222 and forms a through hole. The water-blocking plate 242 is arranged around the output shaft 222 and connected to the outer periphery of the waterproof sleeve 241. The water-blocking structure 240, composed of the waterproof sleeve 241 and the water-blocking plate 242, provides good waterproofing effect on the inner ring and a large overall water-blocking range, resulting in a good water-blocking effect.

[0030] In this embodiment, the water baffle 242 is elastic, which can avoid the risk of rigid contact between the water baffle 242 and the cleaning cylinder 310 due to excessive movement when the lifting driver 230 drives the rotating driver 220 and the stirring head 210 to move up and down. This improves the safety of use while maintaining the water baffle effect.

[0031] In this embodiment, the water-blocking plate 242 is made of silicone. Using silicone for the water-blocking plate provides elasticity, good food safety, and relatively reliable operation.

[0032] In the embodiments, reference is made to Figure 4 The outer diameter of the baffle plate 242 is larger than the diameter of the inlet and outlet hole 312, so that the water splashing out from the inlet and outlet hole 312 can be almost completely blocked by the baffle plate 242, further reducing the risk of water splashing out.

[0033] In the embodiments, reference is made to Figure 4 The outer diameter of the waterproof sleeve 241 is smaller than the diameter of the inlet / outlet hole 312, which makes the waterproof effect of the waterproof sleeve 241 more obvious. In addition, the waterproof sleeve 241 will not directly touch the hole wall of the inlet / outlet hole 312 during the lifting and lowering process of the rotating drive 220, thus improving the safety of the lifting and lowering process.

[0034] It is conceivable that in other embodiments, the water-blocking structure 240 may also be other structures, such as an annular plate.

[0035] In the embodiments, reference is made to Figure 3 The stirring mechanism 200 also includes a lifting frame 400, which is slidably connected to the frame 100 in the vertical direction. A rotary driver 220 is connected to the lifting frame 400, and a lifting driver 230 is disposed on the frame 100 and connected to the lifting frame 400. The lifting driver 230 is used to drive the lifting frame 400 to slide up and down. The lifting driver 230 drives the rotary driver 220 and the stirring head 210 to slide up and down through the lifting frame 400 to achieve lifting. The structure is simple and easy to implement.

[0036] Specifically, in this embodiment, the lifting frame 400 is slidably connected to the frame 100 via a slide rail slider structure. It is conceivable that in other embodiments, the lifting frame 400 may also be movable vertically relative to the frame 100 via a guide post and guide sleeve structure.

[0037] Specifically, the lifting drive 230 includes a second motor and a synchronous belt. The synchronous belt is arranged in the vertical direction, and the second motor drives the synchronous belt to move. The lifting frame 400 is fixedly connected to the synchronous belt, so that the lifting frame 400 can be raised and lowered. It is conceivable that in other embodiments, the lifting drive 230 may also adopt a structure such as a cylinder, electric cylinder, hydraulic cylinder, or electric push rod to drive the lifting frame 400 to move up and down.

[0038] In the embodiments, reference is made to Figure 3 The rotary drive 220 is configured as a first motor, which includes a motor body 221 and an output shaft 222 rotatably connected to the motor body 221. The lifting frame 400 is provided with a receiving cavity 410, in which the motor body 221 is located, and the output shaft 222 passes through the cavity wall of the receiving cavity 410. The lifting frame 400 described above can protect the motor body 221 of the first motor, reducing the impact of moisture or dust on the first motor.

[0039] Specifically, the water-blocking structure 240 is mounted on the lifting frame 400, thereby fixing the water-blocking structure 240 relative to the rotary drive 220. It is conceivable that in some other embodiments, the water-blocking structure 240 may also be directly mounted on the motor body 221.

[0040] Specifically, the water supply component 320 includes a water tank and a water pump, which can draw water from the water tank and inject it into the spray nozzle 314 through the outlet. It is conceivable that in some other embodiments, the water supply component 320 may also be a water supply pipe, which is directly connected to an external water source.

[0041] In the embodiments, reference is made to Figure 4 The cleaning cylinder 310 has two water spray nozzles 314 arranged in the vertical direction, which makes it convenient to spray water on different positions above and below the stirring head 210 at the same time, thereby improving the cleaning effect.

[0042] It is conceivable that the cleaning cylinder 310 may also be provided with three or more spray nozzles 314 arranged in the vertical direction, which can be selected by those skilled in the art according to actual needs.

[0043] This application also discloses a milkshake vending machine that employs the aforementioned stirring and cleaning device. Due to the use of this device, the structure of the milkshake vending machine is simplified, reducing manufacturing and assembly costs.

[0044] Specifically, the milkshake vending machine also includes a cup storage mechanism 500, a powder supply mechanism 600, and a cup transfer mechanism 700. The cup storage mechanism 500 can store cups and allow them to fall to the cup transfer mechanism 700. The cup transfer mechanism 700 can move the cups to the powder supply mechanism 600 to obtain the raw materials, and can also move the cups to the mixing mechanism 200 for mixing and preparation.

[0045] Specifically, the milkshake vending machine is also equipped with a wastewater tank 800. Wastewater discharged from the drain outlet 313 of the washing cylinder 310 can flow into the wastewater tank 800 through a pipe for collection.

[0046] Specifically, the milkshake vending machine's frame 100 has a box-like structure, with a dispensing port, payment device, and interactive screen at the front door. The payment device can be a QR code or a coin acceptor, and the interactive screen allows consumers to select their desired items. The stirring and cleaning device, cup storage mechanism 500, powder supply mechanism 600, cup transfer mechanism 700, and wastewater tank 800 are all located within the box-like structure.
