[0026] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0027] Reference Figures 1 to 6 , the embodiment of the present application provides a knob-type cup cover switch, the cup cover switch comprising:

[0028] The upper cover 2 and the lower cover 1 are rotatably connected at one end through a rotating shaft structure 4, and a locking structure 3 is provided at the other end to realize the opening and locking between the upper cover 2 and the lower cover 1. The locking structure 3 includes a knob 31, a switch body 32, a switch mounting portion 13 provided on the lower cover 1, and a switch matching portion 23 located on the upper cover 2. The knob 31 and the switch body 32 are in a sleeve connection relationship and are fixed in the switch mounting portion 13 through a latch 35. The knob 31 can rotate relative to the switch body 32. A spring 34 is provided at the gap between the switch body 32 and the switch mounting portion 13. A locking protrusion 311 is provided on one side of the knob 31 facing the switch mounting portion 13. The switch mounting portion 13 is provided with an annular abutting portion 131 at a position corresponding to the locking protrusion 311, and the locking protrusion 311 abuts against the annular abutting portion 131.

[0029] like Figure 1-2As shown, in this embodiment, the rotating shaft structure 4 includes a rotating shaft mounting portion 41 and a rotating shaft 42. The rotating shaft mounting portion 41 is integrally formed with one end of the lower cover 1, and the rotating shaft 42 is disposed in the rotating shaft mounting portion 41. The upper cover 2 is movably connected to the rotating shaft mounting portion 41 via the rotating shaft 42, thereby realizing the rotating connection between the upper cover 2 and the lower cover 1. In some embodiments, a torsion spring can also be sleeved on the rotating shaft 42, and the two ends of the torsion spring are respectively against the upper and lower covers to achieve the purpose of automatic opening or automatic closing.

[0030] like Figure 2 As shown, in this embodiment, the switch mating portion 23 of the upper cover 2 is provided with an upper engaging tooth 231, and the corresponding switch body 32 is provided with a lower engaging tooth 321, and the upper and lower engaging teeth complete the opening and locking action between the upper cover 2 and the lower cover 1 by biting or releasing.

[0031] like Figure 3-6 As shown, in this embodiment, the knob 31 extends a latch connection column 312 toward the switch mounting seat, and the latch connection column 312 is provided with an arc-shaped latch movable hole 313. A pair of mounting ears 322 are extended from both sides of the switch body 32 toward the switch mounting seat. In addition, a connecting hole 323 is provided at the center of the switch body 32, and the switch body 32 is sleeved on the latch connection column 312 through the connecting hole 323. The switch mounting seat is provided with a latch fixing hole 132, and the latch 35 connects the knob 31 and the switch body 32 to the switch mounting seat through the mounting ears 322 and the latch connection column 312.

[0032] In some embodiments, a protruding column 325 is provided at the connection between the switch body 32 and the spring 34, and one end of the spring 34 is sleeved on the protruding column 325. The other end of the spring 34 abuts against the switch mounting seat, and a sunken spring mounting seat 133 is provided at the abutting position. The protruding column 325 and the spring mounting seat 133 are provided to facilitate the installation and fixation of the spring.

[0033] like Figure 4-5 As shown, in some embodiments, the switch body 32 is provided with an annular through hole 324, and the locking protrusion 311 is penetrated in the annular through hole 324. It should be emphasized that the curvature of the annular through hole 324 is greater than the annular abutting portion 131, so that when the locking protrusion 311 slides in the annular through hole 324, the locking protrusion 311 is in a state of not abutting against the annular abutting portion 131.

[0034] In some embodiments, positioning grooves are provided at both ends of the annular through hole 324. The opening of the positioning groove is larger than the annular through hole 324. The positioning groove is provided so that the locking protrusion 311 has a state of changing sliding resistance when sliding in the annular through hole 324, that is, the sliding resistance of the locking protrusion 311 in the positioning groove is small, and the resistance is large when sliding in the annular through hole 324. Such a setting can improve the unlocking feel of the knob 31.

[0035] In some embodiments, the arc size of the annular abutment portion 131 is 0-1 / 2 arc. In some cases, the arc size may be less than or equal to 1 / 10 arc, 1 / 9 arc, 1 / 8 arc, 1 / 7 arc, 1 / 6 arc, 1 / 5 arc, 1 / 4 arc, 1 / 3 arc, 1 / 2 arc. Optionally, the arc size of the annular abutment portion 131 may be greater than or equal to any value described herein. The arc size of the annular abutment portion 131 may fall within the range between any two values ​​described herein.

[0036] In some embodiments, the contact surface between the annular abutment 131 and the locking protrusion 311 is non-smooth, that is, the contact surface between the annular abutment 131 and the locking protrusion 311 is not flat, so that when the locking protrusion 311 slides on the annular abutment 131, a friction force that hinders the sliding of the locking protrusion 311 is generated. Figure 8 As shown, in this embodiment, the contact surfaces of the annular abutting portion 131 and the locking protrusion 311 are staggered with positioning protrusions 314. The positioning protrusions 314 may be in the shape of strips, spheres, convex blocks or other shapes or a combination of several shapes. When the locking protrusion 311 and the annular abutting portion 131 are relatively displaced, the positioning protrusions 314 can not only increase the friction of the contact surface, but also the appropriate spacing can make the positioning protrusions 314 produce a "clicking" sound when they contact each other, further improving the unlocking experience.

[0037] like Figure 5 As shown, in this embodiment, a notch is provided at the edge of the knob 31. A toggle member 33 is provided at the notch, and the toggle member 33 is fixedly connected or movably connected to the knob 31 through the notch.

[0038] In some embodiments, the toggle member 33 is movably connected to the knob 31. The toggle member 33 is movably connected to the notch via the connecting shaft 331, that is, the toggle member 33 can rotate relative to the knob 31. In addition, the toggle member 33 is arranged along the axis of the knob 31, and the line connecting the toggle member 33 to the axis has an angle with the vertical direction.

[0039] like Figure 7As shown, it is a schematic diagram of the position setting of the toggle member, and the toggle member 33 is arranged around a center of a circle, and the center of the circle is the axis position of the knob 31. The line connecting the toggle member 33 to the center of the circle forms an angle with the vertical direction, and the size of the angle is 0-180°. For example, the angle can be less than or equal to 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, 180°. When the position of the toggle member 33 is set at an angle of 135°, because the knob 31 is unlocked clockwise, the toggle member 33 is located at the lower end of the knob 31 after rotating a certain angle. At this time, pressing the knob 31 to unlock can save effort.

[0040] In some embodiments, the outer contour of the toggle member 33 can be spherical, flower-shaped, heart-shaped, cubic or other shapes, or a combination of several shapes.

[0041] like Figure 3 As shown, in some embodiments, a boss 15 is provided at the joint between the lower cover 1 and the upper cover 2, and the boss 15 is used to abut against the switch matching portion 23, specifically against the upper engaging teeth 231, so as to make the upper and lower covers more secure when locked.

[0042] Reference Figure 1-8 The embodiment of the present invention further provides a cup cover, which includes a direct drinking port 11, a straw 12, a supporting column 22, a pipe plug 21 and the aforementioned cup cover switch.

[0043] Specifically, the lower cover 1 is provided with a direct drinking port 11 and a straw 12 that pass through from top to bottom. The lower cover 1 is concave next to the straw 12 to form a straw receiving groove 121. The lower cover 1 is also provided with a straw locking switch 122 for pressing the head of the straw 12 into the straw receiving groove 121. When the head of the straw 12 is pressed into the straw receiving groove 121 by the straw locking switch 122, the inner hole of the bending portion is squeezed to leave a ventilation gap. The upper cover 2 is provided with a supporting column 22 in the direction of the lower cover 1, so that when the upper cover 2 and the lower cover 1 are closed, the supporting column 22 presses the straw 12 into a partition state to prevent air leakage and liquid leakage. In addition, the upper cover 2 is provided with a pipe plug 21 at the position of the direct drinking port 11. The pipe plug 21 is composed of a plug 211 and a plug connector 212. One end of the plug connector 212 is fixedly connected to the upper cover 2, and the other end is used to cover the plug 211.
