However, its structure is complex, the cost is high, and the operation is cumbersome, making it inconvenient for the operator to use.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems of existing technologies, this invention proposes an ice cream machine that prevents operators from touching the rotating mixing shaft and causing safety hazards. It has a simple structure, low cost, and is easy to operate.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows: An ice cream machine includes a main unit with a stirring shaft and a drive device for rotating and lifting the stirring shaft; a cup assembly detachably mounted on the main unit, coaxially located below the stirring shaft, the cup assembly including a lid and a body, the lid being detachably mounted on the body; and a safety guard slidably mounted on the main unit, located above the lid, and capable of sliding up and down relative to the lid. This design prevents the operator from touching the rotating stirring shaft and causing a safety hazard when the safety guard slides down to contact the lid; and allows the cup assembly to be freely attached and detached from the main unit when the safety guard slides up away from the lid. The machine is simple in structure, low in cost, and easy to operate.

[0007] According to the above solution, the safety guard plate is provided with a sleeve portion, inside which is an elastic body that facilitates the passage of the stirring shaft. The cup lid is provided with a second through hole that facilitates the passage of the stirring shaft. When the safety guard plate slides down to abut against the cup lid, the sleeve portion covers the second through hole, and the elastic body and the cup lid are press-fitted together. This design, through the abutment between the sleeve portion and the cup lid, avoids the safety hazard caused by the exposed stirring shaft; and the sleeve portion covering the second through hole and the press-fitting design of the elastic body and the cup lid prevent food from spilling out and contaminating the table during stirring.

[0008] According to the above scheme, the elastomer is provided with a through hole to facilitate the passage of the stirring shaft; when the stirring shaft passes through the through hole, the through hole and the stirring shaft are press-fitted together. This design prevents the stirring shaft from carrying food out into the main unit during stirring.

[0009] According to the above scheme, the main unit is provided with a sliding groove, and the safety guard plate is provided with a slider, with the slider and the sliding groove slidably connected; a release device and a return spring are provided between the main unit and the safety guard plate; when the safety guard plate slides down to fit or abut against the cup lid, the release device locks the safety guard plate. This design allows the safety guard plate to slide smoothly onto the main unit with the slider and the sliding groove slidably connected, making assembly convenient; the release device between the main unit and the safety guard plate locks the safety guard plate when it slides down to fit or abut against the cup lid, preventing the safety guard plate from rising on its own, ensuring safety and reliability.

[0010] According to the above scheme, the unlocking device includes a positioning hole on the safety guard plate and a knob, a slide rod, and a return spring on the main unit. The return spring is located between the slide rod and the main unit. The knob is used to control the extension or retraction of the slide rod. When the safety guard plate slides down to engage with or abut against the cup lid, the slide rod and the positioning hole correspond. With this configuration, when the safety guard plate slides down to engage with or abut against the cup lid, the slide rod and the positioning hole correspond. At this time, the knob can be rotated to control the slide rod to extend and engage with the positioning hole, thus locking the safety guard plate and preventing it from rising on its own. To unlock, rotating the knob in the opposite direction controls the slide rod to retract, disengaging it from the positioning hole. Under the elastic force of the return spring, the safety guard plate rises and resets on its own.

[0011] According to the above scheme, the knob is provided with a guide groove, and the slide rod is provided with a guide protrusion, with the guide protrusion and the guide groove slidably connected; the gap formed between the inner wall of the guide groove and the outer wall of the knob is set to be larger at one end and smaller at the other end; when the guide protrusion is located at the end with the larger gap in the guide groove, the slide rod is in a retracted state; when the guide protrusion is located at the end with the smaller gap in the guide groove, the slide rod is in an extended state. With this configuration, rotating the knob changes the position of the guide protrusion in the guide groove, thereby controlling the extension or retraction of the slide rod.

[0012] According to the above solution, the main unit is equipped with a safety guard switch. The safety guard is equipped with a control panel, a control PCB board, and a trigger rod. The trigger rod and the safety guard switch are correspondingly configured. When the safety guard slides down to fit or abut against the cup lid, the trigger rod activates the safety guard switch to conduct the circuit. This configuration ensures that the circuit is activated only when the safety guard slides down to abut against the cup lid, making it safer to use.

[0013] According to the above scheme, the main unit is equipped with a cup assembly switch, the cup body is equipped with a connecting rod, and the cup lid is equipped with a cup lid trigger. The cup lid trigger is correspondingly positioned with the upper end of the connecting rod, and the lower end of the connecting rod is correspondingly positioned with the cup assembly switch. When the cup assembly is assembled in place, the connecting rod triggers the cup assembly switch to conduct the circuit. This configuration ensures that the circuit can only be activated after the cup assembly is fully assembled, making it safer to use.

[0014] According to the above solution, the cup lid is equipped with a locking block, and the cup body is equipped with a locking groove, with the locking block and the locking groove connected in a locking manner; the inner wall or bottom wall of the cup is equipped with a convex and concave structure to prevent the food from rotating. With this design, the cup lid and cup body are easy to assemble and disassemble thanks to the locking block and locking groove connection; the convex and concave structure on the inner wall or bottom wall of the cup can form an anti-rotation structure after the food is frozen, resulting in better stirring effect.

[0015] According to the above scheme, the cup assembly is equipped with a stirring blade connected to the stirring shaft, and a magnet is fixed on the cup lid, with the stirring blade and the magnet magnetically attracted to each other. In this configuration, in the initial state, the stirring blade and the magnet are magnetically attracted to each other. During stirring, the stirring shaft passes through the cup lid and couples with the stirring blade, thereby driving the stirring blade to rotate and move up and down within the cup assembly. When the stirring shaft disengages from the cup lid and resets, the stirring blade and the magnet are magnetically attracted to each other again.

[0016] According to the above solution, the main unit is provided with a locking groove, and the cup body is provided with a locking buckle, with the locking buckle and locking groove being connected in a locking manner.

[0021] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 14As shown, the ice cream machine of this utility model includes a main unit 1, on which a stirring shaft 42 and a driving device for driving the stirring shaft 42 to rotate and move up and down are provided; a cup assembly 3, which is detachably installed on the main unit 1 and coaxially located below the stirring shaft 42; the cup assembly 3 includes a cup lid 31 and a cup body 32, with the cup lid 31 detachably installed on the cup body 32; and a safety guard plate 2, which is slidably installed on the main unit 1 and located above the cup lid 31, and can slide up and down relative to the cup lid 31. This design prevents the operator from touching the rotating stirring shaft 42 and causing a safety hazard when the safety guard plate 2 slides downwards to a gap fit or abut against the cup lid 31; and allows the cup assembly 3 to be freely installed and removed from the main unit 1 when the safety guard plate 2 slides upwards away from the cup lid 31. Its structure is simple and its operation is convenient.

[0023] The safety guard plate 2 slides down to fit the cup lid 31 with a gap smaller than the size of a human finger, which can effectively prevent a person's hand from passing through the gap and touching the rotating stirring shaft 42.

[0024] Furthermore, the safety guard plate 2 is provided with a sleeve portion 27, and an elastic body 22 is provided inside the sleeve portion 27 to facilitate the passage of the stirring shaft 42; the cup lid 31 is provided with a second perforation 38 to facilitate the passage of the stirring shaft 42; when the safety guard plate 2 slides down to abut against the cup lid 31, the sleeve portion 27 covers the second perforation 38, and the elastic body 22 and the cup lid 31 are press-fitted together. This arrangement, through the abutment between the sleeve portion 27 and the cup lid 31, prevents the stirring shaft 42 from being exposed and causing a safety hazard; and the sleeve portion 27 covering the second perforation 38, and the press-fitting arrangement of the elastic body 22 and the cup lid 31, prevents food from spilling out and contaminating the tabletop during stirring.

[0025] When the stirring shaft 42 is in stirring operation, the sleeve part 27 is sleeved on the outside of the stirring shaft 42.

[0026] Furthermore, the elastomer 22 is provided with a through hole 210 to facilitate the passage of the stirring shaft 42; when the stirring shaft 42 passes through the through hole 210, the through hole 210 and the stirring shaft 42 are press-fitted together. This arrangement prevents the stirring shaft 42 from carrying food into the main unit 1 during stirring.

[0027] Furthermore, the main unit 1 is provided with a sliding groove 18, and the safety guard plate 2 is provided with a slider 29, with the slider 29 and the sliding groove 18 slidably connected. A release device and a return spring 23 are provided between the main unit 1 and the safety guard plate 2. When the safety guard plate 2 slides downwards to a gap fit or abutment with the cup lid 31, the release device locks the safety guard plate 2. This arrangement allows the safety guard plate 2 to slide smoothly onto the main unit 1 with the slider 29 and the sliding groove 18 in a convenient assembly configuration. The release device between the main unit 1 and the safety guard plate 2 locks the safety guard plate 2 when it slides downwards to a gap fit or abutment with the cup lid 31, preventing the safety guard plate 2 from rising on its own, ensuring safety and reliability.

[0028] Under the elastic force of the return spring 23, in the initial position, the safety guard plate 2 and the cup assembly 3 are spaced apart (e.g., Figure 1 , 2 As shown in Figure 3), this facilitates the assembly and disassembly of the cup assembly 3.

[0029] Furthermore, the unlocking device includes a positioning hole 25 on the safety guard plate 2 and a knob 11, a slide rod 14, and a return spring 15 on the main unit 1. The return spring 15 is located between the slide rod 14 and the main unit 1. The knob 11 is used to control the extension or retraction of the slide rod 14. When the safety guard plate 2 slides down to a gap fit or abutment with the cup lid 31, the slide rod 14 and the positioning hole 25 correspond. With this configuration, when the safety guard plate 2 slides down to a gap fit or abutment with the cup lid 31, the slide rod 14 and the positioning hole 25 correspond. At this time, the knob 11 can be rotated to control the slide rod 14 to extend and engage with the positioning hole 25, thereby locking the safety guard plate 2 and preventing it from rising on its own. To unlock, rotating the knob 11 in the opposite direction will control the slide rod 14 to retract and disengage from the positioning hole 25. Under the elastic force of the return spring 23, the safety guard plate 2 will rise and reset on its own.

[0030] Furthermore, the knob 11 is provided with a guide groove 17, and the slide rod 14 is provided with a guide protrusion 16. The guide protrusion 16 and the guide groove 17 are slidably connected. The gap formed between the inner wall of the guide groove 17 and the outer wall of the knob 11 is set to be larger at one end and smaller at the other. When the guide protrusion 16 is located at the end with the larger gap in the guide groove 17, the slide rod 14 is in a retracted state; when the guide protrusion 16 is located at the end with the smaller gap in the guide groove 17, the slide rod 14 is in an extended state. With this configuration, by rotating the knob 11 to change the position of the guide protrusion 16 in the guide groove 17, the extension or retraction of the slide rod 14 can be controlled.

[0031] Under the elastic force of the return spring 15, the guide protrusion 16 is always kept in close contact with the inner wall of the guide groove 17.

[0032] Furthermore, the main unit 1 is equipped with a safety guard switch 12, and the safety guard 2 is equipped with a control panel 21, a control PCB board 28, and a trigger rod 24. The trigger rod 24 and the safety guard switch 12 are correspondingly arranged. When the safety guard 2 slides down to a gap fit or abut against the cup lid 31, the trigger rod 24 triggers the safety guard switch 12 to conduct the circuit. This arrangement ensures that the circuit is only conducted when the safety guard 2 slides down to a gap fit or abut against the cup lid 31, making it safer to use.

[0033] The positions of the trigger lever 24 and the safety guard switch 12 can also be interchanged.

[0034] Furthermore, the main unit 1 is equipped with a cup assembly switch 13, the cup body 32 is equipped with a connecting rod 36, and the cup lid 31 is equipped with a cup lid trigger part 37. The cup lid trigger part 37 is correspondingly arranged with the upper end of the connecting rod 36, and the lower end of the connecting rod 36 is correspondingly arranged with the cup assembly switch 13. When the cup assembly 3 is assembled in place, the connecting rod 36 triggers the cup assembly switch 13 to conduct the circuit. This arrangement ensures that the circuit can only be conducted after the cup assembly 3 is assembled in place, making it safer to use.

[0035] Furthermore, the cup lid 31 is provided with a locking block 39, and the cup body 32 is provided with a locking groove 310, with the locking block 39 and the locking groove 310 engaging in a locking connection; the inner wall or bottom wall of the cup body 32 is provided with a convex-concave structure 311 to prevent the food from rotating. With this design, the cup lid 31 and cup body 32 are easy to assemble and disassemble with the locking block 39 and the locking groove 310 engaging in a locking connection; the convex-concave structure 311 on the inner wall or bottom wall of the cup body 32 can form an anti-rotation structure after the food is frozen, resulting in better stirring effect.

[0036] Preferably, the convex and concave structure 311 is a convex rib or a groove; when the convex and concave structure 311 is a convex rib, the food will form a groove that complements the convex rib after freezing, and when the convex and concave structure 311 is a groove, the food will form a convex rib that complements the groove after freezing.

[0037] Furthermore, the cup assembly 3 is equipped with a stirring blade 34 corresponding to and connected to the stirring shaft 42, and a magnet 33 is fixed on the cup lid 31, with the stirring blade 34 and the magnet 33 magnetically attracted to each other. In this configuration, initially, the stirring blade 34 and the magnet 33 are magnetically attracted to each other. During stirring, the stirring shaft 42 passes through the cup lid 31 and couples with the stirring blade 34, thereby driving the stirring blade 34 to rotate and move up and down within the cup assembly 3. When the stirring shaft 42 disengages from the cup lid 31 and resets, the stirring blade 34 and the magnet 33 are magnetically attracted to each other again.

[0038] The stirring shaft 42 is equipped with a magnet at its lower end, which makes the coupling with the stirring blade 34 more stable; of course, a magnet can also be installed on the stirring blade 34.

[0039] Furthermore, the main unit 1 is provided with a locking groove 19, and the cup body 32 is provided with a locking buckle 35, which is connected to the locking groove 19. With this arrangement, the cup body 32 and the main unit 1 are easy to assemble with the locking buckle 35 and the locking groove 19 connected.

[0040] Furthermore, the driving device includes a stirring motor 4, a first gearbox 41, a guide sleeve 43, a lifting motor 5, a second gearbox 51, a screw 52, ​​an upper fixed seat 61, a lower fixed seat 62, a guide rod 63, and a linear bearing 64. The stirring motor 4, the first gearbox 41, and the guide sleeve 43 are fixed together by a lifting platform. The output end of the stirring motor 4 is connected to the input end of the first gearbox 41, and the output end of the first gearbox 41 is connected to the stirring shaft 42 to drive the stirring shaft 42 to rotate. The output end of the lifting motor 5 is connected to the input end of the second gearbox 51, and the output end of the second gearbox 51 is connected to the screw 52. The screw 52 is threadedly connected to the lifting platform to drive the lifting platform to move up and down. The upper fixed seat 61 and the lower fixed seat 62 are fixed by the guide rod 63, and the guide rod 63 and the guide sleeve 43 are slidably connected.

[0041] Among them, such as Figure 5 As shown, when the safety guard plate 2 slides down until its lower end face is in clearance fit with or just abuts against the cup lid 31, the trigger rod 24 triggers the safety guard plate switch 12 to conduct the circuit, and the whole machine is in the ready position to start. In this state, the stirring shaft 42 has not yet formed a connection with the stirring blade 34 in the cup assembly 3. In order to enter the normal working state, the lifting motor 5 needs to drive the stirring shaft 42 to move downward, so that the stirring shaft 42 passes through the second through hole 38 on the cup lid 31 and achieves reliable coupling with the stirring blade 34 located in the cup assembly 3. After the coupling is completed, the stirring shaft 42 can synchronously drive the stirring blade 34 to rotate and move up and down in the cup assembly 3 under the drive of the stirring motor 4 and the lifting motor 5, thereby performing the stirring operation.

[0042] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present utility model.
