DETAILED DESCRIPTION

[0022] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0023] like Figure 1 — Fig. 9 As shown, a rotary vacuum bottle comprises a bottle body 1, in which an inner liner 2 is arranged, an upper cover 3 and a lower cover 4 are respectively installed at the upper and lower ends of the bottle body 1, a nozzle 5 is installed at the upper end of the upper cover 3, and it also comprises a head cap 6, a sleeve 7, an adapter sleeve 8 and a positioning cylinder 9, the sleeve 7 is sleeved outside the head cap 6 and slides up and down with the head cap 6, the adapter sleeve 8 is sleeved outside the sleeve 7 and is fixedly connected with the sleeve 7, the upper end of the adapter sleeve 8 is rotatably sleeved on the lower end of the bottle body 1, the upper end of the lower cover 4 is rotatably sleeved on the lower end of the bottle body 1, the lower cover 4 is covered outside the sleeve 7 and the adapter sleeve 8, and the lower cover 4 is fixedly connected to the sleeve 7, the positioning cylinder 9 is fixedly connected to the lower end of the inner liner 2, two spiral grooves 91 are distributed along the circumference on the side wall of the positioning cylinder 9, two protrusions 61 are distributed along the circumference on the outer wall of the upper end of the head cap 6, the protrusions 61 are stuck in the spiral grooves 91 and rotatably cooperate with the spiral grooves 91, and the lower end of the lower cover 4 is opened for the head cap 6 to pass through.

[0024] like Figure 6 , Figure 7 As shown, the inner wall of the lower end of the sleeve 7 has two first clamping blocks 71, and the outer wall of the head cap 6 has two first clamping grooves 62 extending up and down. The first clamping blocks 71 are inserted into the first clamping grooves 62 and slide up and down with the first clamping grooves 62.

[0025] like Figure 7 , Figure 8 As shown, two second slots 72 are formed on the inner wall of the lower end of the sleeve 7 , and two second clamping blocks 81 are formed on the inner wall of the adapter sleeve 8 , and the second clamping blocks 81 are clamped into the second slots 72 .

[0026] like Figure 3 , Figure 4 , Fig. 9 As shown, the upper inner wall of the adapter sleeve 8 has an annular groove 82 , and the lower end of the bottle body 1 has an annular buckle 11 , which is snapped into the annular groove 82 , so that the adapter sleeve 8 and the bottle body 1 are rotatably matched.

[0027] like Figure 5 , Figure 7 As shown, two third clamping blocks 41 are provided on the inner wall of the lower cover 4 , and two third clamping grooves 73 are provided on the outer wall of the lower end of the sleeve 7 , and the third clamping blocks 41 are clamped into the third clamping grooves 73 .

[0028] like Fig.10 As shown, the upper and lower ends of the spiral groove 91 respectively have a first horizontal clamping groove 911 and a second horizontal clamping groove 912. The first horizontal clamping groove 911 and the second horizontal clamping groove 912 are provided to clamp the protrusion 61 more firmly.

[0029] like Figure 6As shown, a convex ring 63 is convexly provided on the outer wall of the lower end of the head cap 6. The inner wall of the lower end of the lower cover 4 is used to block the convex ring 63 to prevent the head cap 6 from falling off.

[0030] When in use, the lower cover 4 is rotated by hand, and the lower cover 4 will drive the sleeve 7, the adapter sleeve 8, and the head cap 6 to rotate together. Because the head cap 6 is slidably matched with the sleeve 7, the protrusion 61 of the head cap 6 will move in the spiral groove 91 of the positioning tube 9, so that the head cap 6 can move up and down. When the head cap 6 moves upward, it can be retracted into the lower cover 4. The up and down movement of the head cap 6 is achieved by rotating the lower cover 4 forward and reversely.

[0031] The rotary vacuum bottle provided by the utility model can extend and retract the head cap 6 after the lower cover 4 is rotated, and after the head cap 6 is inserted into the lower cover 4, the rotary vacuum bottle is not easily pressed by mistake when placed in a bag.
