[0002] Typically, an ice maker includes a tray for making ice and a drive device that automatically removes ice cubes from the tray by rotating the tray. In addition to rotating the tray, the drive device also detects the amount of ice cubes in the ice storage container by rotating an ice detection rod.

[0003] According to the prior art, a driving device for an ice maker includes a driving motor; a cam gear rotated by the driving motor; a lever driven by a first cam surface of the cam gear to rotate an ice detection lever; and a magnetic lever driven along a second cam of the cam gear. The magnetic lever is contacted or disengaged at a contact point between the magnetic lever and a Hall effect IC, thereby outputting a signal. With the above structure, the presence of ice cubes in the ice storage container can be conveniently detected.

[0004] Chinese patent application number CN201310074055.2 discloses a driving device for an ice maker of a refrigerator. A protrusion is formed between a cam surface of an ice detection lever of a cam gear and a cam groove of the ice detection lever, so that the operating lever can be instantly rotated upward and then downward, thereby achieving the effect of shaking the ice detection lever up and down. Therefore, the ice detection lever can be easily and effectively contacted when it is frozen, without the need for additional repair work.

[0005] The above technical solution realizes connection through transmission of multiple components, which has a complex driving mode, high assembly cost, and is inconvenient to assemble and disassemble, thus affecting the promotion and use of the equipment. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1-4 As shown, the portable ice maker drive device of the present invention includes a lower housing 1 and an upper housing 2 clamped on the upper portion of the lower housing 1. The upper housing 2 is provided with an output portion 3 connected to a rotating disk. The lower housing 1 is provided with a driving portion, a transmission portion, and a detection portion 4 connected to an ice detection rod. The driving portion drives the output portion 3 and the detection portion 4 to rotate through the transmission portion.

[0025] A connecting gear is fixedly provided on the outer side of the bottom end of the detection part 4, and a sliding part 18 is provided on one side of the connecting gear. A cam 16 is fixedly provided on the outer side of the bottom end of the output part 3. One end of the cam 16 contacts and abuts against the end of the sliding part 18 to drive the sliding part 18 to move, and one side of the sliding part 18 is engaged with the connecting gear.

[0026] For the convenience of driving, the driving part includes a motor 5 installed in the lower shell 1 and a rotating rod 6 connected to the output end of the motor 5. The transmission part includes a first fixed column 9 and a second fixed column 10. The first fixed column 9 is fixed with a first reduction gear 12 and a transmission gear, and the outer side of the second fixed column 10 is fixed with a second reduction gear 13 and a third reduction gear 14. The first reduction gear 12 is engaged with the helical gear on the outer side of the rotating rod 6, and the transmission gear is engaged with the third reduction gear 14.

[0027] The second transition gear 15 is meshed with the side of the second reduction gear 13 away from the driving part, and the upper part of the second transition gear 15 is connected to the coaxially rotating magnetic rod 11 and the first transition gear 8. A rotating gear 7 is fixed to the lower outer side of the output part 3, and the first transition gear 8 is meshed with the rotating gear 7.

[0028] In order to control the contact between the magnet 17 and the Hall element, the end of the magnetic rod 11 away from the second transition gear 15 is semicircular and rotates through the output part 3. A magnet 17 is fixedly provided at one end of the magnetic rod 11, and a non-contact Hall element corresponding to the magnet 17 is fixedly provided on the side wall of the lower shell 1.

[0029] In order to drive the movement of the detection part 4, the sliding part 18 includes a movable block 181, a conical contact head 182 fixed to the end of the movable block 181 close to the cam 16, and a rack 183 arranged on one side of the movable block 181. The rack 183 is engaged with the connecting gear. A mounting groove 184 is provided at the end of the movable block 181 away from the contact head 182, and a connecting spring 185 is installed in the mounting groove 184. The other end of the connecting spring 185 abuts against the side wall of the lower shell 1.

[0030] In order to stabilize the movement direction of the sliding portion 18 , a guide portion 19 is provided on one side of the sliding portion 18 .

[0031] In summary, the portable ice maker driving device described in the present invention, when in use, first connects the rotating disk and the ice detection rod to the output part 3 and the detection part 4 respectively, and starts the motor 5 after the connection. The motor 5 drives the rotating rod 6 to rotate, and relies on the bevel gear on the outside of the rotating rod 6 to mesh with the first reduction gear 12 to drive the transmission gear to rotate, and then drives the third reduction gear 14 to rotate, and then rotates through the second reduction gear 13 and the second transition gear 15, and then drives the first transition gear 8 and the magnetic rod 11 to rotate coaxially. The first transition gear 8 meshes with the rotating gear 7 to drive the output part 3 to rotate, and at the same time drives the cam 16 to rotate. During the rotation of the cam 16, the end of the cam 16 is used to press the contact head 182, thereby driving the movable block 181 to move along the direction of the guide part 19. During the movement, the detection part 4 is rotated by the meshing of the rack 183 and the connecting gear. As the cam 16 rotates, the detection part 4 rotates upward instantly and then rotates downward, and the force generated by the instantaneous vertical shaking of the ice detection rod in conjunction with the detection part 4 can remove ice.
