[0036] As Figures 1-16 shown, the present invention provides a small ice lolly machine based on a thermoelectric cooling chip, including a base 14. An outer shell is provided at the upper end of the base 14. The outer shell includes a bottom case 15, an outer cover 1, and an upper cover 2.

When the semiconductor refrigeration chip 10 is working, one end of the semiconductor refrigeration chip 10 is the cold side and the other end is the hot side. The cold side is in contact with the refrigeration box 9, and the hot side is in contact with the heat sink 11, that is, when the semiconductor refrigeration chip 10 is working, The refrigeration box 9 can be continuously cooled so that the liquid inside the refrigeration box 9 freezes into ice to form popsicles; the upper cover 2 is used to seal the upper end of the outer cover 1 to protect the internal components of the outer cover 1, and the sealing cover 4 is used to seal the upper port of the refrigeration box 9 to form a closed space inside the refrigeration box 9 to improve the refrigeration efficiency; the setting of the grille 5 corresponds to the heat sink 11 one by one, and through the set grille 5, when the heat dissipation fan 17 is working, the heat on the heat sink 11 can be blown to the outside, thereby accelerating the heat dissipation effect of the heat sink 11 and further improving the working efficiency of the semiconductor refrigeration chip 10; the base 14 is used to install electronic components such as power supply components; the popsicle machine is very small and convenient, very suitable for outdoor use, and through the set semiconductor refrigeration chip 10, the whole device has low energy consumption and fast ice formation, and can be detachably installed through the upper cover 2, the outer cover 1, and the bottom shell 15, which is convenient for cleaning after use, thereby ensuring the cleanliness of the device.

[0038] The sealing cover 4 is provided with a handle 3 , the inner wall of the lower end of the sealing cover 4 is provided with a slot 6 , the upper end of the refrigeration box 9 is provided with a protrusion 8 , and the lower end of the sealing cover 4 is provided with a recess 7 matched with the protrusion 8 .

[0039] like Figures 1-3 As shown, a convex groove is provided at the upper end of the outer cover 1, and a concave groove is provided at the lower end of the upper cover 2. The concave groove and the convex groove are interference fit, so that the upper cover 2 can be detachably installed on the outer cover 1; the notch 7 and the convex mouth 8 are also interference fit, which can make the sealing cover 4 firmly fixed on the refrigeration box 9, and seal and insulate the refrigeration box 9; the provided handle 3 is convenient for removing the sealing cover 4, and the sealing cover 4 is fixed to the inner wall of the upper cover 2. When removing the sealing cover 4, the upper cover 2 can be removed, so that the refrigeration box 9 is opened, which is convenient for taking out materials or cleaning; the provided slot 6 is convenient for supporting a wooden stick. By inserting the wooden stick into the slot 6, after the sealing cover 4 is buckled on the refrigeration box 9 to make popsicles, it is convenient to take the popsicles.

[0040] A threaded groove 12 is provided at the lower end of the outer surface of the outer cover 1, and a threaded cylinder 13 matching the threaded groove 12 is provided at the upper end of the bottom case 15.

[0041] As Figure 2 , Figures 6-7 shown, the bottom case 15 is fixedly connected to the base 14, the threaded cylinder 13 is fixedly connected to the bottom case 15, and through the threaded connection between the threaded groove 12 and the threaded cylinder 13, the threaded cylinder 13 and the bottom case 15 can be disassembled, facilitating regular cleaning of the inside of the heat dissipation fan 17, the bottom case 15, and the bottom of the outer cover 1.

[0042] A plurality of filter nets 16 are provided on the outer surface of the bottom case 15, and the heat dissipation fan 17 is rotatably installed inside the bottom case 15.

[0043] As Figure 6 shown, when the heat dissipation fan 17 works, it can suck the outside air through the filter net 16 into the inside of the bottom case 15. The filter net 16 can filter the air, thus preventing foreign impurities from being sucked into the device. There is also a motor inside the heat dissipation fan 17, and the motor is fixed inside the bottom case 15. When the motor works, it can drive the heat dissipation fan 17 to rotate, thereby accelerating the heat dissipation of the heat sink 11. It is equivalent to the heat dissipation fan 17 being rotatably installed inside the bottom case 15.

[0044] The power supply component is a plurality of detachable dry batteries.

[0045] Since the power consumption of the semiconductor refrigeration chip 10 and the heat dissipation fan 17 is small, setting dry batteries as the power supply component can meet the power supply requirements. A dry battery slot box is provided at the bottom of the base 14, and the dry batteries can be detachably installed inside the slot box. Due to the large number of dry batteries and their wide range of applications, when choosing to set dry batteries as the power supply component, the ice cream machine can better integrate into life.

[0046] The power supply component is a detachable mobile power supply 24. A power supply box 21 is provided on the inner wall of the base 14, and the mobile power supply 24 is placed inside the power supply box 21. A support plate 22 matching the mobile power supply 24 is provided inside the power supply box 21. A power supply pressing cover 18 that can be flipped is provided at the lower end of the base 14. When the power supply pressing cover 18 is flipped, the support plate 22 can be moved to push the mobile power supply 24 out of the power supply box 21.

[0047] As Figures 7-10 shown, the mobile power supply 24 can be detachably charged and recycled. The power supply box 21 is used to load and accommodate the mobile power supply 24. The support plate 22 is used to support the mobile power supply 24, and a conductive seat electrically connected to the mobile power supply 24 is also provided on the support plate 22, which can supply the power of the mobile power supply 24 to the corresponding electronic components. The power supply pressing cover 18 functions to press the mobile power supply 24 and seal the power supply box 21. When the power supply pressing cover 18 is coplanar with the lower end surface of the base 14, the power supply pressing cover 18 can press and fix the mobile power supply 24 toFigure 8 , Figure 10 For illustrative purposes, when the power supply gland 18 is turned upwards, it no longer presses on the mobile power supply 24 at this time, and the power supply box 21 opens. The corresponding mobile power supply 24 can be pushed by the pallet 22, that is, moved upwards and pushed out of the power supply box 21, which facilitates the taking of the mobile power supply 24 at this time. The power supply component can also be a rechargeable battery integrated with the base 14, which can be charged and recycled multiple times and is integrally provided with the base 14 and cannot be disassembled.

[0048] A long rotating shaft 19 is rotatably connected to the inner wall of the base 14. The power supply gland 18 is rotatably connected to the outer surface of the long rotating shaft 19. Two ends of the outer surface of the long rotating shaft 19 are respectively sleeved with torsion springs 20 that cooperate with the power supply gland 18. A locking device that cooperates with the power supply gland 18 is also provided on the base 14.

[0049] As Figures 7-10 shown, the power supply gland 18 is rotatably connected to the base 14 through the long rotating shaft 19, which is equivalent to being hinged to the base 14. Through the provided torsion spring 20, a driving force can be applied to the power supply gland 18, so that the power supply gland 18 can be turned upwards and opened under normal conditions. Through the provided locking device, when the power supply gland 18 and the base 14 are coplanar, the locking device can lock the power supply gland 18. At this time, the power supply gland 18 can stably press the mobile power supply 24. A rubber pad is also provided on the power supply gland 18. When the power supply gland 18 and the rubber pad press the mobile power supply 24, a certain buffering effect can be achieved.

[0050] The pallet 22 is slidably connected to the inner wall of the power supply box 21. Four end corners of the inner wall of the bottom end of the power supply box 21 are respectively provided with return springs 23 that cooperate with the pallet 22. First square tubes 26 are fixedly connected to the left and right side end faces of the pallet 22. Rectangular holes that cooperate with the first square tubes 26 are respectively opened on the left and right inner walls of the power supply box 21. Clamping plates 30 are respectively provided on both sides of the power supply box 21. First wedge-shaped blocks 28 that cooperate with the clamping plates 30 are respectively slidably connected to the inner walls of the first square tubes 26. First springs 27 that cooperate with the first wedge-shaped blocks 28 are respectively provided on the inner walls of the bottom ends of the first square tubes 26.

[0051] As Figures 11-13 shown, the pallet 22 can be slidably connected to the inner wall of the power supply box 21 up and down. The return spring 23 always has a downward driving force on the pallet 22, so that the pallet 22 can eject the mobile power supply 24 under normal conditions. The first square tube 26 can move up and down in the inner wall of the rectangular hole, that is, the pallet 22 is limited to only move up and down. The first wedge-shaped block 28 can slide left and right in the inner wall of the first square tube 26. The first spring 27 always has a driving force on the first wedge-shaped block 28 towards the outside, so that the first wedge-shaped block 28 is in an extended state under normal conditions. The installation and shape of the first wedge-shaped block 28 and the clamping plate 30 are as Figure 13 shown, in order to Figure 13For illustrative purposes, when the first square tube 26 and the first wedge-shaped block 28 move from top to bottom, the inclined surface of the first wedge-shaped block 28 will meet the clamping plate 30. Under the contact and engagement between the inclined surface and the clamping plate 30, the first wedge-shaped block 28 can be moved inward, that is, the first wedge-shaped block 28 enters the inner wall of the first square tube 26 and compresses the first spring 27. When the first square tube 26 and the first wedge-shaped block 28 move downward to the lower end of the clamping plate 30, at this time, the first wedge-shaped block 28 is disengaged from the clamping plate 30, and the first wedge-shaped block 28 can pop out and reset outward under the elastic force of the first spring 27; when the first square tube 26 and the first wedge-shaped block 28 move from bottom to top, at this time, the straight surface of the first wedge-shaped block 28 can contact the clamping plate 30, and the upward movement of the first wedge-shaped block 28 can be prevented under the block of the clamping plate 30; when installing the mobile power supply 24, by placing the mobile power supply 24 on the tray 22 and pressing it downward, when the mobile power supply 24 is pressed downward, the tray 22, the first square tube 26, the first wedge-shaped block 28, etc. can move downward, and the return spring 23 is compressed. When the first wedge-shaped block 28 moves downward to the lower end position of the clamping plate 30, at this time, the first wedge-shaped block 28, the first square tube 26, the tray 22, etc. move to the bottommost position, that is, they no longer move downward, and then the mobile power supply 24 can be fixed by flipping the power supply cover 18.

[0052] On the inner walls of the left and right ends of the base 14, second square tubes 32 are respectively slidably connected. On the inner walls of the second square tubes 32, second wedge-shaped blocks 33 are respectively slidably connected. On the inner walls of the bottom ends of the second square tubes 32, second springs 34 are respectively provided which cooperate with the second wedge-shaped blocks 33. On the inner walls of the left and right ends of the power supply box 21, round seats 37 are also respectively provided. On the inner walls of the round seats 37, connecting shafts 39 are respectively rotatably connected. On the inner wall of the round base 14, small coil springs 38 which cooperate with the connecting shafts 39 are also provided. On the outer sides of the outer surfaces of the two connecting shafts 39, latch pins 31 which cooperate with the second wedge-shaped blocks 33 are respectively provided. The clamping plates 30 are respectively arranged on the inner sides of the outer surfaces of the two connecting shafts 39. On one end surface of each of the second square tubes 32, an extension rod 35 is fixedly connected. On both sides of the base 14, long connecting rods 36 are also respectively provided. One end of each long connecting rod 36 is respectively hinged on the power supply cover 18, and the other end of each long connecting rod 36 is respectively hinged on the extension rod 35.

[0053] As Figures 8-10 、 Figures 13-15 shown, the second square tube 32 can slide back and forth on the inner wall of the base 14, the second wedge-shaped block 33 can slide up and down on the inner wall of the second square tube 32, the second spring 34 always has an upward driving force on the second wedge-shaped block 33, which can make the second wedge-shaped block 33 be in the outermost top state under normal conditions. The installation and shape of the second wedge-shaped block 33, the disc 29, the latch pin 31, and the clamping plate 30 are as Figure 14 shown, and the installation and shape of the connecting shaft 39 and the small coil spring 38 are as Figure 15As shown, a baffle 40 is fixedly connected to the outer surface of the connecting shaft 39, and a stop pin 41 is fixedly connected to the upper surface of the circular seat 37. With the cooperation of the baffle 40 and the stop pin 41, the limit pin 31 can only swing backward. And under the winding force of the small coil spring 38, the pin 31 and the clamping plate 30 are in a parallel state under normal conditions, that is, as Figure 13 shown, the clamping plate 30 and the first wedge-shaped block 28 are collinear. When the second square tube 32 and the second wedge-shaped block 33 move from front to back, the straight surface of the second wedge-shaped block 33 can meet and engage with the pin 31. The second wedge-shaped block 33 can drive the pin 31 to swing backward. When the pin 31 swings backward, it can drive the disc 29 to rotate and the clamping plate 30 to swing forward. When the clamping plate 30 swings forward to a specified position, it can disengage from the first wedge-shaped block 28. At this time, the first wedge-shaped block 28, the support plate 22, etc. will move upward and reset under the elastic force of the return spring 23, so as to push the mobile power supply 24 upward and out of the inside of the power box 21. When the second square tube 32, the second wedge-shaped block 33, etc. continue to move backward, they can disengage from the pin 31. After disengaging from the pin 31, under the self-winding force of the small coil spring 38, the disc 29, the pin 31, and the clamping plate 30 can rotate in the reverse direction and reset, that is, the clamping plate 30 flips to a parallel state and can cooperate with the first wedge-shaped block 28 again; when the second square tube 32, the second wedge-shaped block 33, etc. move from back to front, at this time, the inclined surface of the second wedge-shaped block 33 can meet and engage with the pin 31. Since the pin 31 cannot swing forward under the cooperation and block of the baffle 40 and the stop pin 41, when the inclined surface of the second wedge-shaped block 33 meets and engages with the pin 31, the second wedge-shaped block 33 can enter the inner wall of the second square tube 32 and compress the second spring 34. When the second wedge-shaped block 33 moves forward to completely disengage from the pin 31, at this time, the second wedge-shaped block 33 will pop out under the elastic force of the second spring 34, that is, reset to the initial state again. By setting the second square tube 32 and the second wedge-shaped block 33, the pin 31 can be unidirectionally driven to swing, that is, it can drive the pin 31 to swing when moving backward and no longer drive the pin 31 to swing when moving forward; as Figure 8As shown in the figure, when it is necessary to disassemble and replace the mobile power supply 24, the power supply gland 18 is driven to turn upwards, that is, it turns upwards under the self-elastic force of the torsion spring 20. When the power supply gland 18 turns upwards, one end of the long connecting rod 36 can be driven to turn upwards, and the other end of the long connecting rod 36 will drive the extension rod 35, the second square tube 32, the second wedge-shaped block 33, etc. to move backwards. When the second wedge-shaped block 33 moves backwards, it can drive the pin 31 to swing backwards, and the corresponding clamping plate 30 swings forwards. When the clamping plate 30 swings forwards to be out of contact with the first wedge-shaped block 28, at this time, the support plate 22 can move upwards under the self-elastic force of the return spring 23, that is, push the mobile power supply 24 upwards. When the power supply gland 18 turns upwards to the vertical state and is completely opened, the corresponding second wedge-shaped block 33 can move backwards to be out of contact with the pin 31. At this time, the pin 31, the clamping plate 30, etc. will return to the parallel state under the self-elastic force of the small coil spring 38, that is, the clamping plate 30 can cooperate with the second wedge-shaped block 33 again. After removing the mobile power supply 24 and installing a new mobile power supply 24, by pressing down the mobile power supply 24, the support plate 22, etc., the first wedge-shaped block 28 can move to the lower end position of the clamping plate 30 again, that is, it can contact and engage with the clamping plate 30 again. At this time, by driving the power supply gland 18 to turn downwards and close, the corresponding second square tube 32 and the second wedge-shaped block 33 can move forwards and reset. When the second wedge-shaped block 33 moves forwards and resets, it will not drive the pin 31 to swing forwards, that is, the corresponding clamping plate 30 can stably engage with the first wedge-shaped block 28, that is, the replacement of the mobile power supply 24 is completed.

[0054] An extension plate 42 is fixedly connected to one side end face of the power supply gland 18, and a hook 43 is fixedly connected to the extension plate 42. The locking device includes a wedge-shaped stopper 44 slidably connected to the base 14. A long guide rod 46 is fixedly connected to the wedge-shaped stopper 44, a pull ring 47 is fixedly connected to the long guide rod 46, and a third spring 45 cooperating with the wedge-shaped stopper 44 is also sleeved on the outer surface of the long guide rod 46.

[0055] As Figure 9 or Figure 16As shown, an installation groove is also formed on the base 14. The long guide rod 46, the third spring 45, the wedge-shaped stopper 44, the stop pin 41, the hook 43, etc. are respectively installed in the installation groove. The long guide rod 46 and the wedge-shaped stopper 44 can slide back and forth on the inner wall of the base 14. The third spring 45 always has a backward driving force on the wedge-shaped stopper 44. When the wedge-shaped stopper 44 is in the rearmost position, it can contact and engage with the hook 43, that is, block the hook 43 to prevent the hook 43 from moving upward and the power supply cover 18 from flipping upward. When it is necessary to open the power supply cover 18, by pulling the pull ring 47 forward, the long guide rod 46 can be driven to move forward. When the long guide rod 46 moves forward, it can drive the wedge-shaped stopper 44 to move forward and compress the third spring 45. When the wedge-shaped stopper 44 moves forward to disengage from the hook 43, at this time the hook 43 is no longer blocked, and the corresponding power supply cover 18 can be flipped upward under the drive of the torsion spring 20 to open. After replacing the new mobile power supply 24, by driving the power supply cover 18 to flip downward, the hook 43 can be moved downward to engage with the wedge-shaped stopper 44 again, and the hook 43 is locked again under the block of the wedge-shaped stopper 44, that is, the corresponding power supply cover 18 is in a stable closed state.
