[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the specific implementation methods thereof are described in detail below in conjunction with the accompanying drawings:

[0046] See also Figures 1 to 9 In an embodiment of the present invention, a novel rotary replacement mechanism is composed of a tray 6, a tray top cover 5, a rotating ring 8, four limit assemblies 7 distributed on the tray 6 and two connecting rods 9 distributed on the rotating ring 8.

[0047] The circumference of the tray 6 has four limiting grooves 61 distributed at 90 degrees, and a limiting component 7 is arranged in each limiting groove 61. Each limiting component 7 is composed of a limiting slider 71, a spring 72, a baffle 73 and a connecting shaft 74. The limiting slider 71 is fixed to one end of the connecting shaft 74, and the limiting slider 71 and the connecting shaft 74 are integrally formed. The baffle 73 is sleeved on the other end of the connecting shaft 74, and the spring 72 is sleeved on the connecting shaft 74. The connecting shaft 74 passes through the through hole 62 in the corresponding limiting groove 61, and the limiting slider 71 and the spring 72 are located on the inner side of the limiting groove 61, and the baffle 73 is located on the outer side of the limiting groove 61 and is fixed by a nut 75.

[0048] The top of the inner wall of the tray 6 is provided with two top cover positioning grooves 63 distributed at 180 degrees; the bottom of the tray 6 is provided with two rotation circle limiting grooves 64 distributed at 180 degrees.

[0049] The tray top cover 5 is snapped onto the top end of the tray 6 , and two top cover ribs 51 distributed 180 degrees are arranged at the bottom end of the tray top cover 5 . The two top cover ribs 51 of the tray top cover 5 are snapped into the two top cover positioning grooves 63 of the tray 6 one by one.

[0050] The rotating ring 8 is clamped on the bottom end of the tray 6 and can rotate axially. The inner wall of the rotating ring 8 is provided with two rotating ring bosses 81 distributed at 180 degrees; the two rotating ring bosses 81 of the rotating ring 8 are arranged one by one in the two rotating ring limiting grooves 64 of the tray 6, and each rotating ring boss 81 moves in the corresponding rotating ring limiting groove 64 to limit the rotation angle of the rotating ring 8.

[0051] The upper end surface of the rotating ring 8 is provided with four rotating ring ribs 82 distributed at 90 degrees. The four rotating ring ribs 82 on the upper end surface of the rotating ring 8 are matched with the blocking pieces 73 of the limiting assembly 7 in the four limiting grooves one by one, so that when the rotating ring 8 rotates counterclockwise, the limiting slider 71 of the limiting assembly is driven to move away from the axis direction, and when the rotating ring 8 rotates clockwise, the limiting slider 71 of the limiting assembly is reset. Specifically, the rotating ring rib 82 is located between the corresponding blocking piece 73 of the limiting assembly and the outer side of the tray 6, and the rotating ring rib 82 is an inclined arc structure. When the rotating ring 8 rotates, the blocking piece 73 of the limiting assembly moves along the outer side of the rotating ring rib 82, so that when the rotating ring 8 rotates counterclockwise, the limiting slider 71 of the limiting assembly is driven to move away from the axis direction (move outward), and when the rotating ring 8 rotates clockwise, the limiting slider 71 of the limiting assembly is reset under the action of the spring.

[0052] Two rotating circle slots 83 distributed at 180 degrees are arranged on the outer circumference of the rotating circle 8. A connecting rod 9 is clamped in each rotating circle slot 83. The connecting rod 9 is used to connect the outer shoulder sleeve of the replaceable vacuum bottle, so that the rotating circle is driven to rotate together when the outer shoulder sleeve rotates.

[0053] The novel rotary replacement mechanism of the present invention is used in a replaceable vacuum bottle. The rotating circle 8 can be connected to the outer shoulder sleeve through the connecting rod 9. The upper end opening of the inner bottle of the replacement core assembly is clamped in the limit sliders 71 of the four limit assemblies. The rotating circle 8 can be driven to rotate by rotating the outer shoulder sleeve. When the rotating circle 8 rotates counterclockwise, the four limit sliders 71 move outward and open at the same time, and the replacement core assembly can be taken out. When the rotating circle 8 rotates clockwise, the four limit sliders 71 are reset at the same time, and then a new replacement core assembly can be installed. The replacement operation is simple.

[0054] See also Figures 10 to 14 A replaceable vacuum bottle, comprising the above-mentioned novel rotating replacement mechanism, further comprising an outer bottle 1, an inner shoulder sleeve 41, an outer shoulder sleeve 42, a large ring 3, a pump core 43, a press cap 44 and a replacement core assembly 2, wherein:

[0055] The large circle 3 and the novel rotating replacement mechanism are arranged one above the other in the inner shoulder sleeve 41, and the upper outer side of the tray top cover 5 is clamped in the lower opening of the large circle 3; the upper end of the large circle 3 is clamped in the upper opening of the inner shoulder sleeve 41;

[0056] The outer shoulder sleeve 42 is rotatably sleeved on the outside of the inner shoulder sleeve 41. Specifically, the lower part of the inner wall of the outer shoulder sleeve 42 is provided with an annular groove 421, and the lower part of the outer wall of the inner shoulder sleeve 41 is provided with an annular boss 411, and the annular boss 411 is provided in the annular groove 421 with clearance fit (see Figure 1), two inner shoulder sleeve through holes 412 distributed at 180 degrees are arranged on the circumference of the inner shoulder sleeve 41, and two outer shoulder sleeve grooves distributed at 180 degrees are arranged on the inner wall of the outer shoulder sleeve 42, and two connecting rods 9 pass through the two inner shoulder sleeve through holes 412 one by one and are clamped in the corresponding outer shoulder sleeve grooves; when the outer shoulder sleeve 42 makes axial rotation outside the inner shoulder sleeve 41, the rotating circle 8 of the new rotary replacement mechanism is driven to rotate together through the connecting rod 9.

[0057] The outer bottle 1 is a cylindrical structure with openings at the upper and lower ends. The upper opening of the outer bottle 1 is clamped in the lower opening of the inner shoulder sleeve 41; the middle part of the pump core 43 is clamped in the large circle 3, and the press cap 44 is arranged on the upper end of the pump core 43; the outer cover of the press cap 44 is covered with the main product cover 10.

[0058] The replacement core assembly 2 consists of an inner bottle 21 , a pump sleeve 22 , a piston 23 and a bottom cover 24 . The pump sleeve 22 is arranged in the upper end opening of the inner bottle 21 , the piston 23 is arranged in the inner bottle 21 , and the bottom cover 24 is clamped in the lower end opening of the inner bottle 21 .

[0059] An outer side of the upper opening of the inner bottle 21 is provided with a mouth ring groove 211 , the inner bottle 21 is arranged in the outer bottle 1 , and the mouth ring groove 21 of the inner bottle 21 is clamped in the four limit assemblies 7 , and the lower part of the pump core 43 is interference fit in the pump sleeve 22 .

[0060] Specifically, the limiting slider 71 has a lower inclined surface 711 at the bottom; the mouth ring groove 211 has an upper inclined surface 212 at the top; when the mouth ring groove 211 of the inner bottle 21 hits the limiting sliders 71 of the four limiting assemblies, the upper inclined surface 212 of the mouth ring groove of the inner bottle 21 moves along the lower inclined surface of the limiting slider 71, so that the spring 72 of the limiting assembly 7 contracts, and the four limiting sliders 71 all move outward. When the bottom end surface of the mouth ring groove of the inner bottle 21 passes through the upper end surface of the limiting slider 71, the limiting slider 71 is quickly reset under the action of the spring 72, and the limiting slider 71 clamps the mouth ring groove 211 of the inner bottle.

[0061] When the replacement core assembly 2 is not installed in the outer bottle, the upper opening of the inner bottle is clamped with a replacement core cover 25, so that the replacement core assembly 2 can be sealed and the material body will not be contaminated.

[0062] When installing the replaceable vacuum bottle of the present invention, first assemble the components of the new rotating replacement mechanism except the connecting rod 9, that is, assemble the tray, the tray top cover, the rotating circle and the four limit assemblies, and then fit the upper outer side of the tray top cover 5 with the inner wall of the lower end of the large circle 3 through the clamping fit, and then the whole is put into the inner shoulder sleeve 41, and the upper outer side of the large circle 3 is clamped together with the inner shoulder sleeve 41; at this time, the connecting rod 9 is passed through the inner shoulder sleeve through holes 412 on both sides of the inner shoulder sleeve 41, and one end of the connecting rod 9 is fitted into the rotating circle clamping groove 83 on the outer side of the rotating circle 8, and then the outer shoulder sleeve 42 is inserted from the upper end of the inner shoulder sleeve 41. Note that the two outer shoulder sleeve clamping grooves distributed 180 degrees on the inner wall of the outer shoulder sleeve 42 are respectively matched with the protruding parts of the other ends of the two connecting rods 9, and the outer shoulder sleeve 42 and the inner shoulder sleeve 41 are matched through the gap between the annular groove and the boss, and the outer shoulder sleeve 42 can be axially rotated on the inner shoulder sleeve, and the rotating circle 8 of the rotating replacement mechanism can be driven to rotate together through the connecting rod 9 while rotating. Then assemble the outer bottle 1, the pump core 43, the push cap 44, the main product cover 10 and other components. At this time, except for the replacement core assembly 2, the other components are assembled.

[0063] When loading the replacement core assembly, first open the replacement core cover 25 of the replacement core assembly, and then push it upward from the lower end opening of the outer bottle 1. When the mouth ring groove 211 of the inner bottle 21 hits the limit slider 71 of the limit assembly 7, the upper inclined surface 212 of the mouth ring groove 211 and the lower inclined surface 711 of the limit slider 71 interact with each other, so that the spring 72 of the limit assembly contracts, and the four limit sliders 71 all move to the outside of the bottle. When the bottom end surface of the mouth ring groove 211 of the inner bottle passes through the upper end surface of the limit slider 71, the limit slider 71 is quickly reset under the action of the spring 72. At this time, the limit slider 71 clamps the mouth ring groove 711 part of the inner bottle, and at the same time, the lower part of the pump core is inserted into the pump sleeve 22 with interference fit, completing the loading action of the replacement core assembly.

[0064] When the material in the inner bottle is used up and the replacement core assembly needs to be taken out, one only needs to hold the entire bottom of the packaging material with his left hand and rotate the outer shoulder sleeve 42 counterclockwise with his right hand. The outer shoulder sleeve 42 drives the rotating circle 8 to rotate counterclockwise through the connecting rod 9. The four rotating circle convex ribs 82 on the upper end surface of the rotating circle 8 correspond one by one to the blocking pieces 73 of the four limiting assemblies 7, so that when the rotating circle 8 rotates counterclockwise, it drives the limiting slider 71 of the limiting assembly to move away from the axial direction (move outward). The limiting slider 71 opens, and the inner bottle 21 falls into the left hand, and the replacement core assembly 2 can be taken out.

[0065] Similarly, the outer shoulder sleeve 42 is rotated clockwise to reset, and the outer shoulder sleeve 42 drives the rotating circle 8 to rotate clockwise through the connecting rod 9. The limit slider 71 is reset under the action of the spring, and then a new replacement core assembly is loaded to repeat the above replacement core assembly loading action; the replacement action is simple, fast, convenient and hygienic.

[0066] To sum up, the novel rotary replacement mechanism and the replaceable vacuum bottle containing the mechanism of the present invention improve the current situation of discarding existing packaging bottles after use through the novel rotary replacement mechanism. After the main product is used up, it only needs to replace the replacement core packaging to continue using it; and the replacement core part does not include a pump core, and has fewer parts, so that the discarded part has lower cost and is more environmentally friendly; the replacement operation is convenient and quick, and the separate replacement core is not only in a sealed state that the material body will not be contaminated, but also more convenient, quick, safe and stable to replace.
