[0031] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] like Figure 1 and Figure 2 As shown, a transmission mechanism 1 provided in one embodiment of the present invention includes a motor 11, a first gear assembly 12, a second gear assembly 13, a lead screw 14, a stirring rod 15, and a transmission box 16 with a receiving space 161; the first gear assembly 12 and the second gear assembly 13 are both installed in the receiving space 161.

[0033] The first output end of the motor 11 is connected to the stirring rod 15 through the first gear assembly 12, and the stirring rod 15 is connected to the lead screw 14 through the second gear assembly 13;

[0034] The second gear assembly 13 is provided with a threaded through hole 131, and the lead screw 14 is threadedly connected to the threaded through hole 131.

[0035] The first gear assembly 12 is composed of multiple meshing gears, and the second gear assembly 13 is also composed of multiple meshing gears. The motor 11 is located outside the transmission box 16, and the stirring rod 15 and the lead screw 14 both pass through the transmission box 16.

[0036] Preferably, the lead screw 14, the stirring rod 15, and the first output end of the first motor 11 are parallel to each other.

[0037] Specifically, the first output end of the motor 11 drives the stirring rod 15 to rotate through the first gear assembly 12, and the stirring rod 15 drives the lead screw 14 to rotate through the second gear assembly 13. During the rotation of the lead screw 14, it will drive the second gear assembly 13 and the transmission box 16 to move through the threaded through hole 131.

[0038] In this embodiment, one motor 11 can drive the stirring rod 15 to rotate and move. The transmission mechanism 1 has a compact structure, occupies little space, and has low manufacturing cost. In addition, the motor 11 is located to the side of the lead screw 14 and the stirring rod 15. The axial direction of the motor 11 only needs to be connected to the first gear assembly 12, which further improves the compactness of the transmission mechanism 1 and further reduces the space occupied by the transmission mechanism 1.

[0039] In one embodiment, such as Figure 2 and Figure 3 As shown, the first gear assembly 12 includes a first transmission gear 121, a second transmission gear 122, a third transmission gear 123 and a fourth transmission gear 124, and the third transmission gear 123 is provided with a through hole 1231.

[0041] The first output end of the motor 11 extends into the receiving space 161 and is connected to the first transmission gear 121, and the second transmission gear 122 is located between the first transmission gear 121 and the third transmission gear 123.

[0042] In this embodiment, the first gear assembly 12 is composed of a first transmission gear 121, a second transmission gear 122, a third transmission gear 123, and a fourth transmission gear 124. Therefore, the first gear assembly 12 has the function of reducing speed and increasing torque, ensuring the stirring force of the stirring rod 15. Furthermore, the lead screw 14 passes through the through hole 1231, thus the lead screw 14 and the third transmission gear 123 are coaxially arranged, further improving the compactness of the transmission mechanism 1.

[0043] In one embodiment, such as Figure 3 As shown, the second transmission gear 122 includes a first gear body 1221 and a second gear body 1222 arranged coaxially, and the third transmission gear 123 includes a third gear body 1232 and a fourth gear body 1233 arranged coaxially, and the through hole 1231 passes through the third gear body 1232 and the fourth gear body 1233;

[0044] The first gear body 1221 meshes with the first transmission gear 121, the second gear body 1222 meshes with the third gear body 1232, and the fourth gear body 1233 meshes with the fourth transmission gear 124.

[0045] In this configuration, the first gear body 1221 and the second gear body 1222 form a double gear, and the third gear body 1232 and the fourth gear body 1233 also form a double gear. The diameter of the first transmission gear 121 is smaller than the diameter of the first gear body 1221, the diameter of the first gear body 1221 is larger than the diameter of the second gear body 1222, the diameter of the second gear body 1222 is smaller than the diameter of the third gear body 1232, the diameter of the third gear body 1232 is larger than the diameter of the fourth gear body 1233, and the diameter of the fourth gear body 1233 is smaller than the diameter of the fourth transmission gear 124.

[0046] In this embodiment, both the second transmission gear 122 and the third transmission gear 123 are designed as double gears, which further improves the speed reduction and torque increase effect of the first gear assembly 12 and further improves the compactness of the transmission mechanism 1.

[0047] In one embodiment, such as Figure 2 and Figure 3 As shown, the second gear assembly 13 includes a planetary gear set 132, a sixth gear 133, a seventh gear 134, and a sleeve 135 with a threaded through hole 131;

[0048] The planetary gear set 132 is mounted on the stirring rod 15, the seventh gear 134 is fixedly sleeved on the sleeve 135, and the lead screw 14 is threadedly connected to the threaded through hole 131; the sixth gear 133 meshes with the planetary gear set and the seventh gear 134.

[0049] The sleeve 135 can be fixedly installed on the transmission box 16.

[0050] Specifically, the stirring rod 15 rotates through the planetary gear set 132, the planetary gear set 132 drives the seventh gear 134 to rotate through the sixth gear 133, and the seventh gear 134 drives the lead screw 14 to rotate through the sleeve 135. At the same time, the first gear assembly 12, the second gear assembly 13, and the transmission box 16 all move along the lead screw 14.

[0051] In this embodiment, the planetary gear set 132 has a good effect of speed reduction and torque increase, and its structure is compact and occupies little space.

[0052] In one embodiment, such as Figure 3 and Figure 4 As shown, the planetary gear set includes a first disc 1321, a second disc 1322, an output gear 1323, a sun gear 1324, multiple planet gears 1325, and a ring gear 1326; all the planet gears 1325 are rotatably mounted between the first disc 1321 and the second disc 1325; the stirring rod 15 is fixedly connected to the first disc 1321, the sun gear 1324 is fixedly mounted on the first disc 1321 and meshes with all the planet gears 1325; the ring gear 1326 is disposed on the inner wall of the accommodating space and meshes with all the planet gears 1325.

[0053] The output gear 1323 is mounted on one end of the second disc 1322 away from the planetary gear 1325 and meshes with the sixth gear 133.

[0054] The first disc 1321 is mounted on the bottom of the planetary gear 1325, and the second disc 1322 is mounted on the top of the planetary gear 1325. Preferably, the gear ring 1326 and the transmission housing 16 are integrally formed parts.

[0055] Specifically, the stirring rod 15 drives the first disc 1321 to rotate, the first disc 1321 drives the planetary gear 1325 and the sun gear 1324 to rotate, the sun gear 1324 drives the second disc 1322 to rotate, the second disc 1322 rotates through the output gear 1323, the output gear 1323 drives the seventh gear 134 to rotate through the sixth gear 133, and the seventh gear 134 drives the lead screw 14 to rotate through the sleeve 135.

[0056] In this embodiment, the planetary gear set has a simple structure and low manufacturing cost.

[0057] In one embodiment, such as Figure 1 and Figure 2 As shown, the transmission mechanism 1 also includes a fan 17, which is installed at the second output end of the motor 11.

[0058] The first output terminal is located at the upper part of the motor 11, and the second output terminal is located at the lower part of the motor 11. While the motor 11 drives the first gear assembly 12 to rotate, it also drives the fan 17 to rotate. The rotating fan 17 can cool down the motor 11 and other components.

[0059] In one embodiment, such as Figure 1 As shown, the transmission mechanism 1 also includes a base 181, a top seat 182, and a guide rod 183; the opposite ends of the guide rod 183 are respectively mounted on the base 181 and the top seat 182;

[0060] The transmission box 16 is also provided with a guide hole, and the transmission box 16 is slidably mounted on the guide rod 183 through the guide hole.

[0061] Multiple guide rods 183 can be provided according to actual needs, and the guide hole penetrates through the transmission box 16.

[0062] Specifically, the lead screw 14 can drive the transmission box 16 to move between the base 181 and the top seat 182, and the transmission box 16 moves along the guide rod 183 through the guide hole, thereby ensuring the stability of the movement of the transmission box 16.

[0063] In one embodiment, such as Figure 1As shown, the transmission mechanism 1 further includes a limiting component; the limiting component includes a first trigger 191, a second trigger 192, and a trigger switch 193; the trigger switch 193 is mounted on the transmission box 16, the first trigger 191 is mounted on the base 181, the second trigger 192 is mounted on the top seat 182, and the trigger switch 193 is used to trigger the first trigger 191 or the second trigger 192.

[0064] The first trigger 191, the second trigger 192, the trigger switch 193, and the motor 11 are all electrically connected to the control board.

[0065] Specifically, during the process of the motor 11 driving the transmission box 16 to move upward, the trigger switch 193 on the transmission box 16 abuts against the second trigger 192 on the top seat 182, and the motor 11 will stop driving the transmission box 16 to move upward; during the process of the motor 11 driving the transmission box 16 to move downward, the trigger switch 193 on the transmission box 16 abuts against the first trigger 191 on the base 181, and the motor 11 will stop driving the transmission box 16 to move downward.

[0066] In this embodiment, the design of the limiting component can limit the vertical movement of the housing 2 and the stirring rod 15, thus ensuring the stability of the transmission mechanism 1.

[0067] like Figure 5 As shown, another embodiment of the present invention also provides an ice cream making device, including a housing 2 and the aforementioned transmission mechanism 1, wherein the transmission mechanism 1 is installed in the internal space of the housing 2.

[0068] The stirring rod 15 extends into the external environment after passing through the transmission box 16 and the internal space at one end away from the second gear assembly 13; the stirring blade 32 is connected to the stirring rod 15 and can stir ice cream.

[0069] In this invention, the transmission mechanism 1 has a compact structure and occupies little space, thus the ice cream making equipment can be manufactured in a relatively small size, making it convenient for home use.

[0070] In one embodiment, such as Figure 5 As shown, the ice cream making equipment also includes a cup assembly 3, which includes a receiving cup 31 and a stirring blade 32 that rotates within the receiving cup 31; the end of the stirring rod 15 away from the second gear assembly 13 is detachably connected to the stirring blade 32.

[0071] The stirring rod 15 is connected to the stirring blade 32. The transmission mechanism 1 drives the stirring blade 32 to rotate in the container 31, and can also move it up and down in the container 31. Thus, the stirring blade 32 stirs the ice cream in the container 31, making the frozen ice cream soft.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
