DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1

[0030] See also Figures 1 to 8As shown, the present embodiment relates to a gear-driven suction nozzle cup cover, which includes an upper cover 1, a lower cover 2, a suction nozzle 3, a straw connector 4, a rotating gear ring 5, a switch 6 and a gear transmission assembly 7. The top of the lower cover 2 is provided with a mounting groove 21, and a receiving groove 11 is arranged at a position corresponding to the mounting groove 21 on the upper cover 1. A water outlet 22 and an exhaust port 23 are arranged on the mounting groove 21. One end of the suction nozzle 3 is hinged to the mounting groove 21 through a hinge shaft 31. When the suction nozzle 3 is flipped upward, the suction nozzle 3 is connected to the water outlet 22. When the suction nozzle 3 is flipped downward, the suction nozzle 3 can be hidden in the receiving groove 11, and the suction nozzle 3 is disconnected from the water outlet 22. The rotating gear ring 5 is installed between the upper cover 1 and the lower cover 2, and the straw connector 4 is installed at the water outlet 22. The upper part of the straw connector 4 is used for docking the suction nozzle 3, and the lower part is used for connecting the suction straw 8. The switch 6 is fixedly connected to the rotating gear ring 5. After turning the switch 6, the rotating gear ring 5 can be driven to rotate. The rotating gear ring 5 is connected to the suction nozzle 3 through the gear transmission assembly 7. After rotating the gear ring 5, the suction nozzle 3 can be turned over by the gear transmission assembly 7 to achieve communication with the straw connector 4 below.

[0031] In an embodiment of the present application, the gear transmission assembly 7 specifically includes a first rack 71 installed on the inner wall of the rotating gear ring 5, a first gear 72 installed on the lower cover 2 through a gear shaft 75 and meshing with the first rack 71, a rack group 73 meshing with the first gear 72 for transmission, and a second gear 74 meshing with the rack group 73 for transmission, and the second gear 74 is connected to the end of the hinge shaft 31 of the suction nozzle 3.

[0032] Specifically, the rack group 73 includes a slider 731, a slide groove 732 is provided at the bottom of the slider 731, a second rack 733 is provided on the side of the slider 731, and a third rack 734 is provided on the top of the slider 731. The second rack 733 is meshed with the first gear 72, and the third rack 734 is meshed with the second gear 74. A slide rail 24 is provided on the lower cover 2, and the slide groove 732 is connected to the slide rail 24 to realize the horizontal movement of the rack group 73.

[0033] In the embodiment of the present application, the rotating gear ring 5 is located on the inner side of the upper cover 1, and the outer wall of the rotating gear ring 5 is provided with two rows of protruding contact points 51 to play the role of suspending the rotating gear ring 5, which can ensure that the rotating gear ring 5 does not contact the inner wall of the upper cover 1 in a large range, thereby avoiding the difficulty of rotating the rotating gear ring 5. In addition, a flange 52 is provided at the bottom of the rotating gear ring 5, and an arc groove 25 is provided at the top of the lower cover 2. The flange 52 is located in the arc groove 25, and the arc groove 25 can limit the rotation range of the rotating gear ring 5.

[0034] In addition, in order to improve the sealing performance of the exhaust port 23, an exhaust sealing silicone 9 is installed at the exhaust port 23. The exhaust sealing silicone 9 is provided with a flange structure 91 in the circumference. The flange structure 91 of the exhaust sealing silicone 9 is flipped up to block the exhaust port 23. When the suction nozzle 3 absorbs water, the internal air pressure decreases, and the atmospheric pressure presses down the flange structure 91 of the exhaust sealing silicone 9, and the exhaust port 23 is opened for exhaust. When no water is absorbed, the internal and external air pressures are the same, and the flange structure 91 of the exhaust sealing silicone 9 is flipped up again to block the exhaust port 23 through its own deformation ability. The suction nozzle 3 blocks the exhaust port 23 after flipping down, which has a certain dust-proof effect. The two ends of the hinge shaft 31 are respectively installed on the mounting groove 21 through steel rings 32. The surface of the steel ring 32 is smooth to reduce friction, thereby reducing the friction loss of the suction nozzle 3 and avoiding the problems of loosening, leakage and poor rotation of the product. The steel ring 32 can be limited by a baffle or a slot structure to prevent it from moving outward. A second limiting plate 12 is disposed on the upper cover 1 . The second limiting plate 12 is located just on the top of the first gear 72 , and can limit the first gear 72 .

[0035] In the embodiment of the present application, a first limit plate 26 is provided on the lower cover 2. The first limit plate 26 can ensure that the first rack 71 on the rotating gear ring 5 will not be affected by external forces and will not be stuck with the first gear 72, thereby avoiding smooth meshing. A protective ring 27 is also provided on the outer side of the first gear 72.

[0036] Example 2

[0037] like Fig. 9 As shown, this embodiment discloses a water cup, which includes a cup body 10 and the gear-driven suction nozzle cup cover in Example 1, the lower cover 2 is threadedly connected to the cup body 10, a sealing ring 20 is sleeved on the lower cover 2, and a handle 30 is also installed on one side of the lower cover 2.

[0038] The working principle of the utility model is:

[0039] The upper cover 1 is provided with the letters "OPEN", "CLOSE" and a direction arrow above the installation position of the switch 6, telling the user that the nozzle 3 can be raised or lowered by moving the switch 6 in the direction of the arrow. When the switch 6 is moved clockwise, the first rack 71 on the rotating gear ring 5 also moves clockwise, driving the first gear 72 to rotate clockwise, further driving the rack group 73 to move forward, so that the second gear 74 rotates counterclockwise, and finally drives the nozzle 3 to rise. At this time, the hole on the nozzle 3 will be connected to the hole of the straw connector 4 to form a channel. At the same time, when the nozzle 3 starts to absorb water, the exhaust port 23 can exhaust. When the switch 6 is moved counterclockwise, the first rack 71 on the rotating gear ring 5 also moves counterclockwise, driving the first gear 72 to rotate counterclockwise, driving the rack group 73 to move backward, so that the second gear 74 moves clockwise, and finally drives the nozzle 3 to lower. At this time, the nozzle 3 presses the straw connector 4 to prevent water leakage, and also blocks the top of the exhaust sealing silicone 9 to play a dust-proof role.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
