DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment 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 making creative work are within the scope of protection of the utility model.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment discloses a replaceable vacuum bottle, including an outer bottle 1, an inner bottle 2, a pump sleeve 3, a pump core 4, a shoulder sleeve 5, a push head 6, and an outer cover 7. The pump core 4 is fixedly installed on the pump sleeve 3. The pump core 4 is provided with a second annular groove 41. The inner wall of the pump sleeve 3 is provided with a second convex ring 33 corresponding to the second annular groove 41. The pump core 4 is installed upward from the lower opening of the pump sleeve 3 so that the second convex ring 33 of the pump core 4 is inserted into the second annular groove 41 for fixing.

[0029] like Figure 3 , Figure 6 , Figure 7As shown, the pump sleeve 3 can be detachably installed at the upper end opening of the inner bottle 2, the inner bottle 2 is provided with a second slot 21, the second slot 21 is connected to the upper end surface of the inner bottle 2, the inner wall of the pump sleeve 3 is provided with a plug board 31 corresponding to the second slot 21, the plug board 31 is inserted into the second slot 21 to limit the rotation direction of the pump sleeve 3 installed on the inner bottle 2, the inner bottle 2 is provided with a first annular groove 22, the inner wall of the pump sleeve 3 is provided with a first convex ring 32 corresponding to the first annular groove 22, the first annular groove 22 and the first convex ring 32 are engaged to limit the upper and lower directions of the pump sleeve 3 installed on the inner bottle 2, so that the pump sleeve 3 can be fixed at the upper end opening of the inner bottle 2, the first convex ring 32 can be separated from the first annular groove 22 by pulling the inner bottle 2 downward with force, the lower end of the pump core 4 extends into the interior of the inner bottle 2, and the lower end of the pump core 4 contacts the liquid in the inner bottle 2.

[0030] like Figure 2 , Figure 3 As shown, the shoulder sleeve 5 is fixedly connected to the pump sleeve 3, and the shoulder sleeve 5 includes an outer sleeve 51 and an inner sleeve 52. The shoulder sleeve 5 is composed of two parts and can use two different materials. The outer sleeve 51 and the inner sleeve 52 are fixedly installed, and the two can be fixed by glue. The inner sleeve 52 and the pump sleeve 3 are fixed by threads, and the inner wall of the inner sleeve 52 is provided with threads corresponding to the outer wall of the pump sleeve 3. The outer sleeve 51 and the outer bottle 1 are detachable and installed, and the shoulder sleeve 5 and the pump sleeve 3 are fixed by threaded connection, and the inner bottle 2 and the pump sleeve 3 are detachably connected by upper and lower buckles. When the inner bottle 2 is plugged in and out, the connection between the shoulder sleeve 5 and the pump sleeve 3 will not be affected.

[0031] like Figure 3 , Figure 4 , Figure 5As shown, the shoulder sleeve 5 is detachably mounted on the upper opening of the outer bottle 1, and at least a part of the inner bottle 2 is located inside the outer bottle 1. When the shoulder sleeve 5 is mounted on the outer bottle 1, the inner bottle 2 is located inside the outer bottle 1. The inner wall of the outer bottle 1 is provided with a first slot 11 and a first clamping slot 12. The first slot 11 is arranged in a horizontal direction. A clamping strip 13 is formed between the first clamping slot 12 and the first slot 11. The first slot 11 includes an open end 111 and a closed end 112. The first clamping slot 12 is located on one side of the closed end 112. The shoulder sleeve 5 is provided with an insert block 511 and a clamping block 512. A second clamping slot 513 cooperating with the clamping strip 13 is formed between the clamping block 512 and the insert block 511. The shoulder sleeve 5 is rotated to allow the insert block 11 to be inserted. 511 and the card block 512 can enter the first slot 11 from the open end 111. When the card block 512 reaches the closed end 112, it can pass over the card strip 13 and enter the first card slot 12. At the same time, the card strip 13 is inserted into the second card slot 513. At this time, the outer bottle 1 is fixed to the shoulder sleeve 5. The end of the card block 512 away from the insertion block 511 is provided with a rounded corner 5121. The rounded corner 5121 can better enable the card block 512 to pass over the card strip 13. At the same time, the edges on both sides of the card strip 13 are rounded to facilitate the card block 512 to pass over the card strip 13 from two directions. The shoulder sleeve 5 and the outer bottle 1 rotate in the opposite direction to enable the card block 512 to be disengaged from the first card slot 12, so that the shoulder sleeve 5 can be removed from the outer bottle 1.

[0032] like Figure 3 , Figure 4 , Figure 5 As shown, the inner wall of the outer bottle 1 is provided with a step 14, and the outer wall of the shoulder sleeve 5 is provided with a retaining ring 514. The retaining ring 514 is located above the insert block 511, and the lower end surface of the retaining ring 514 is against the step 14, which limits the depth of the shoulder sleeve 5 installed on the outer bottle 1. The retaining ring 514 can cover the structure of the connecting part between the shoulder sleeve 5 and the outer bottle 1, play a role in shielding and dust prevention, and make the connection between the shoulder sleeve and the outer bottle 1 more beautiful after removing the outer cover 7.

[0033] like Figure 2 , Figure 3 As shown, when the shoulder sleeve 5 is separated from the outer bottle 1, the inner bottle 2, pump sleeve 3, pump core 4 and shoulder sleeve 5 are separated from the outer bottle 1 as a whole. When the inner bottle 2, pump sleeve 3, pump core 4 and shoulder sleeve 5 are separated from the outer bottle 1 as a whole, the inner bottle 2 can be separated from or loaded into the shoulder sleeve 5. After the inner bottle 2, pump sleeve 3, pump core 4 and shoulder sleeve 5 are removed from the outer bottle 1 together, the inner bottle 2 may be removed and replaced, reducing the parts of the replacement package that need to be replaced, retaining the pump sleeve 3 and pump core 4, reducing the cost consumption of the replacement package, and being more environmentally friendly.

[0034] like Figure 3 , Figure 8As shown, the press head 6 is provided with a connecting pipe 61, which is inserted into the upper end of the pump core 4, the press head 6 passes through the shoulder sleeve 5, and a limit block 62 is provided on the outer wall of the press head 6. A stop shoulder 515 is provided at the upper opening of the shoulder sleeve 5, and the stop shoulder 515 forms a limit above the limit block 62. The press head 6 is first installed on the upper end of the pump core 4, and then installed together with the pump core 4 from the lower opening of the shoulder sleeve 5. The limit block 62 is blocked by the stop shoulder 515 for limiting, so as to prevent the press head 6 from falling out of the shoulder sleeve 5.

[0035] like Figure 3 As shown, the outer cover 7 is installed at the upper end of the outer bottle 1, the outer surface of the outer bottle 1 is provided with protrusions, and the inner wall of the outer cover 7 is provided with corresponding grooves. The outer cover 7 consists of an inner and outer part. The inner and outer layers can be made of different materials, and the inner and outer sides can be fixed by snap fasteners to obtain different appearance effects.
