DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings. Example 1

[0028] This embodiment mainly describes a rotatable detachable cup cover, as follows:

[0029] like Figures 1 to 7As shown, a rotary detachable cup cover is used with a cup to cover the cup mouth. The cup cover includes a cover body 1, a concave slide groove 11 is provided on the cover body 1, one side of the slide groove 11 is close to the edge of the cover body 1, a strip slide hole 12 and a direct drinking port 13 are provided in the slide groove 11, and the direct drinking port 13 is located near the edge of the cover body 1. A sliding member 2 that can close or open the direct drinking port 13 is slidably provided on the cover body 1, and the sliding member 2 slides along the slide groove 11. The slide groove 11 has a guiding and limiting effect on the sliding member 2. The sliding member 2 includes a first sliding cover 2 1. Connecting shaft 22, two limit blocks 23 and return spring 24. The first sliding cover 21 is located in the slide groove 11 and can slide back and forth relative to the slide groove 11, thereby closing or opening the direct drinking port 13. The connecting shaft 22 is fixed to the bottom of the first sliding cover 21 and passes through the cover body 1 from the strip-shaped slide hole 12. The connecting shaft 22 is preferably integrally formed with the first sliding cover 21. The two limit blocks 23 are symmetrically arranged on both sides of the end of the connecting shaft 22. The return spring 24 is sleeved on the connecting shaft 22. The connecting shaft 22 is sleeved with a set of limit blocks 23 that cooperate with the connecting shaft 22. The rotary cover 3 is limited to prevent the connecting shaft 22 from slipping. A limit platform 31 is provided inside the rotary cover 3. The return spring 24 is located between the limit platform 31 and the cover body 1 and provides elastic force for the rotary cover 3. The rotary cover 3 can slide up and down on the connecting shaft 22 to squeeze the return spring 24. The rotary cover 3 has a channel 32 adapted to the connecting shaft 22 and the two limit blocks 23. Two limit grooves 33 are symmetrically provided on the lower end surface of the rotary cover 3, which are misaligned with the channel 32 and cooperate with the two limit blocks 23. The connecting shaft 22 is inserted from the channel 32 to sleeve the rotary cover 3 on the connecting shaft 22 The rotating cover 3 is squeezed to compress and deform the return spring 24. After the two limit blocks 23 pass through the channel 32, the rotating cover 3 is rotated to make the two limit blocks 23 hook into the two limit grooves 33 respectively to limit the connecting shaft 22. At this time, the first sliding cover 21 is pushed to slide in the slide groove 11, and the connecting shaft 22 slides in the strip slide hole 12 as the first sliding cover 21 slides. When the first sliding cover 21 completely covers the top of the direct drinking port 13, the direct drinking port 13 is closed. When the first sliding cover 21 slides in the direction away from the direct drinking port 13, the direct drinking port 13 is opened. When cleaning the cup cover, push the rotating cover 3 upward to deform the return spring 24, and the two limit blocks 23 disengage from the limit grooves 33. Then rotate the rotating cover 3 to align the two limit blocks 23 with the channels 32, and then slide the connecting shaft 22 and the limit blocks 23 out along the channels 32 and the strip-shaped sliding holes 12. Then, the sliding member 2 installed on the cup cover can be disassembled. This is simple and quick, and will not cause damage to the toggle member. After disassembly, the stains on the cover body 1 can be thoroughly cleaned.

[0030] like Figure 3 、 Figure 4 and 7As shown, the connection between the connecting shaft 22 and the first sliding cover 21 is a rectangular block 221 adapted to the width of the strip sliding hole 12. The rectangular block 221 can slide along the strip sliding hole 12 and drive the first sliding cover 21 to slide to open or close the direct drinking mouth 13. The setting of the rectangular block 221 further improves the stability of the first sliding cover and the connecting shaft 22, and avoids the connecting shaft 22 from rotating relative to the strip sliding hole 12 during the sliding process, which causes the first sliding cover 21 to deviate and collide with the slide groove 11 to cause it to get stuck.

[0031] Specifically, the sliding member 2 also includes a second sliding cover 25, which is sleeved on the connecting shaft 22 and can slide relative to the bottom surface of the cover body 1 to block or open the lower end of the direct drinking port 13. The specific connection method is as follows: the second sliding cover 25 is provided with a through hole 251 for the connecting shaft 22 and the two limit blocks 23 to pass through. The upper side of the through hole 251 is a rectangular hole 2511 adapted to the rectangular block 221, and the lower side of the through hole 251 is a circular hole 2512 adapted to the connecting shaft 22. A limiting step 222 is provided on the connecting shaft 22, and a limiting ring groove 2 is formed between the limiting step 222 and the rectangular block 221. 23. A sealing ring 224 is provided on the limiting ring groove 223. When the connecting shaft 22 is installed on the cover body 1, the sealing ring 224 has an interference fit with the side wall of the through hole 251. When the first sliding cover 21 slides, the connecting shaft 22 slides with the first sliding cover 21 within the strip-shaped sliding hole 12, and the second sliding cover 25 slides with the sliding of the connecting shaft 22. When the first sliding cover 21 slides to completely close the top of the direct drinking port 13, the second sliding cover 25 completely closes the bottom of the direct drinking port 13. When the first sliding cover 21 gradually moves away from the direct drinking port 13, the second sliding cover 25 also gradually moves away from the direct drinking port 13. The provision of the rectangular hole 2511 provides a positioning and guiding function for the second sliding cover 25, preventing the second sliding cover 25 from rotating on the connecting shaft 22 during the sliding process driven by the connecting shaft 22.

[0032] Specifically, the bottom surface of the second sliding cover 25 is provided with a connecting tube 252 that covers the through hole 251. An abutment platform is provided within the connecting tube 252. The rotating cover 3 has an annular mounting groove 34 whose opening faces the connecting tube 252. The inner diameter of the annular mounting groove 34 is larger than the outer diameter of the connecting tube 252 and forms a mounting space with the connecting tube 252. The return spring 24 is located within the mounting space, the stop platform 31 is located within the annular mounting groove 34, and the channel 32 is located below the stop platform 31. One end of the return spring 24 abuts against the lower surface of the abutment platform, and the other end abuts against the upper surface of the stop platform 31. There is a gap between the annular mounting groove 34 and the end of the connecting tube 252 to provide space for the return spring 24 to deform.

[0033] Specifically, the transverse cross-section of the connection between the connecting shaft 22 and the two limiting blocks 23 is runway-shaped, the channel 32 is a runway-shaped channel 32 , and the two limiting grooves 33 are preferably perpendicular to the channel 32 .

[0034] like Figure 1、 Figure 2 and Figure 4 The first sliding cover 21 is provided with a raised pushing portion 211. Pushing the pushing portion 211 can make the first sliding cover 21 and the second sliding cover 25 slide to open or close the direct drinking port 13. The design of the first sliding cover 21 is not only convenient for pushing the first sliding cover 21, but also when pushing the first sliding cover 21, the pushing portion 211 is the force point, which is more labor-saving.

[0035] like Figure 1 and Figure 7 As shown, the edge of the cover body 1 has an annular outer wall 14 extending vertically upward, and an inwardly concave guide groove 15 is provided on the outer wall 14 near the direct drinking port 13. One end of the slide 11 is connected to the guide groove 15. After the water flows out of the direct drinking port 13, it flows out through the guide groove 15. The setting of the guide groove 15 has a diversion effect to prevent water from not being able to gather and dissipating heat everywhere. Example 2

[0036] This embodiment mainly describes a thermos cup, which is specifically as follows:

[0037] like Figures 1 to 7 As shown, a thermos cup includes a cup body 4 and the above-mentioned cup cover, the cup cover is threadedly connected to the cup body, the cup body includes an outer cup body 41 and an inner cup body 42, and a vacuum insulation layer 43 is provided between the outer cup body 41 and the inner cup body 42. The direct drinking port 13 of the cup cover is connected to the inner cup body 42. When the first sliding cover 21 on the cup cover is pushed to open the direct drinking port 13, the water in the inner cup body 42 flows out through the direct drinking port 13.

[0038] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the present invention is usually placed when in use.
