DETAILED DESCRIPTION

[0020] See also Figure 1-Figure 5The utility model provides the following technical solutions: it includes an outer shell 1, an inner cavity of the outer shell 1 is provided with an installation cavity 11, and the top of the outer shell 1 is detachably connected to a shoulder sleeve 12, a nozzle 13 is provided on the top of the shoulder sleeve 12, the inner walls on both sides of the installation cavity 11 are rotatably connected to the limiting frame 2, and the inner walls on both sides of the installation cavity 11 are provided with a connecting groove 21, a connecting suction cup 3 is provided at the bottom of the inner cavity of the installation cavity 11, the bottom end of the connecting suction cup 3 is connected to a connecting shell 31, the bottom of the inner cavity of the installation cavity 11 is fixedly connected to a support frame 32, the bottom end of the outer shell 1 is detachably connected to a blocking rod 4, the bottom end of the blocking rod 4 is provided with a blocking block 41, and the bottom end of the outer shell 1 is embedded with a rubber block 42.

[0021] In this embodiment: the new type is provided with an outer shell 1, an installation cavity 11, a shoulder sleeve 12, a nozzle 13 and a nozzle 131 to form the external structure of the cosmetic bottle. The inner walls on both sides of the installation cavity 11 are rotatably connected to the limiting frame 2, and the inner walls on both sides of the installation cavity 11 are provided with a connecting groove 21. The limiting frame 2 limits the replacement core entering the installation cavity 11. As the replacement core moves downward, the two limiting frames 2 are squeezed, thereby driving the limiting frame 2 to rotate, so that the limiting frame 2 rotates toward the inside of the connecting groove 21 to make way for the replacement core. Under the limit of the limiting frame 2, the replacement core is avoided. The free-replacement core quickly slides to the bottom of the inner cavity of the installation cavity 11. A connecting suction cup 3 is provided at the bottom of the inner cavity of the installation cavity 11. The bottom of the connecting suction cup 3 is connected to a connecting shell 31. The bottom of the inner cavity of the installation cavity 11 is fixedly connected to a support frame 32. The bottom end of the outer shell 1 is detachably connected to a blocking rod 4. A blocking block 41 is provided at the bottom end of the blocking rod 4, and a rubber block 42 is embedded at the bottom end of the outer shell 1. The replacement core moves down to contact the bottom end of the connecting suction cup 3. Continue to press the replacement core downward to drive the connecting suction cup 3 to move downward, so that the connecting shell 31 is lowered outside the blocking rod 4. The connecting shell 31 slides until it contacts the convex surface of the bottom end of the support frame 32. At this time, the top and bottom ends of the connecting suction cup 3 are both sealed structures. During the sliding of the connecting shell 31, the replacement core blocks the top of the connecting suction cup 3, and the air inside the connecting suction cup 3 is discharged through the gap between the connecting shell 31 and the blocking rod 4. When the bottom end of the connecting shell 31 is blocked, the inner cavity of the connecting suction cup 3 becomes closed, thereby tightly sucking the replacement core. The connecting suction cup 3 has elasticity, so that the installation cavity 11 can be suitable for various heights. The replacement core increases the scope of application of the present invention. The blocking rod 4 and the blocking block 41 form a structure for sealing the support frame 32. When the replacement core is fixed, the blocking rod 4 and the blocking block 41 are tightly connected with the blocking rod 4 and the rubber block 42. When the replacement core needs to be replaced, the blocking block 41 and the blocking rod 4 are pulled out from the support frame 32 and the through groove 33. At this time, the inner cavity of the connecting suction cup 3 is no longer a closed structure, so that the connection between the connecting suction cup 3 and the replacement core is released, thereby releasing the limit on the replacement core, and the replacement core is easily taken out from the inside of the installation cavity 11 for replacement.

[0022] The top of the outer shell 1 and the inner wall of the shoulder sleeve 12 are provided with matching connecting threads 121, and the outer shell 1 and the shoulder sleeve 12 are detachably connected through the connecting threads 121; by providing the connecting threads 121, it is convenient to connect the shoulder sleeve 12 and the outer shell 1, which is more convenient when replacing the replacement core.

[0023] A torsion spring 22 is provided at one end of the limit frame 2, and a connecting plate 221 is fixedly connected to the inner walls on both sides of the installation cavity 11. The limit frame 2 is rotatably connected to the connecting plate 221 through the torsion spring 22; by providing the torsion spring 22, the limit frame 2 can start to rotate after being squeezed, and when the pressure on the limit frame 2 disappears, the limit frame 2 is automatically reset by the torsion spring 22.

[0024] A seal 311 is fixedly connected to the support frame 32. The inner and outer diameters of the seal 311 match the inner diameter of the connecting shell 31, and the seal 311 is sleeved on the outside of the support frame 32. By setting the seal 311, the gap between the connecting shell 31 and the support frame 32 is sealed, so that the bottom end of the connecting shell 31 is blocked, and the inner cavity of the connecting suction cup 3 is closed, so that it can be used as a suction cup to replace the replacement core.

[0025] A slot 411 is provided at the bottom of the rubber block 42 , and the diameter of the blocking block 41 matches the inner diameter of the slot 411 ; by providing the slot 411 , the position of the blocking block 41 is limited to maintain its stability, thereby maintaining its sealing effect on the inner cavity of the connecting suction cup 3 .

[0026] A through slot 33 is provided at one end of the support frame 32, and the sealing rod 4 passes through the through slot 33 and the bottom of the outer shell 1; the through slot 33 allows the support frame 32 and the sealing rod 4 to be detachably connected, and when the replacement core is disassembled, it is convenient to adjust the state of the connecting suction cup 3, thereby releasing the limit on the replacement core.

[0027] The blocking rod 4 and the blocking block 41 are an integrated structure, and the blocking rod 4, the blocking block 41 are seamlessly connected to the through groove 33 and the card slot 411; the blocking rod 4 and the blocking block 41 are integrated, and the sealing effect is higher. The blocking rod 4, the blocking block 41 and the through groove 33 and the card slot 411 are seamlessly connected to increase the sealing effect.

[0028] The working principle and usage process of the present invention are as follows: when replacing the replacement core, the shoulder sleeve 12 is rotated to separate it from the outer shell 1, and the replacement core is placed inside the installation cavity 11. As the replacement core moves downward, the two limit frames 2 are squeezed, thereby driving the limit frames 2 to rotate, so that the limit frames 2 rotate toward the inside of the connecting groove 21, making way for the replacement core. Under the limit of the limit frame 2, the replacement core is prevented from sliding quickly to the bottom end of the inner cavity of the installation cavity 11. The replacement core moves down to abut against the bottom end of the connecting suction cup 3, and continues to press the replacement core downward to drive the connecting suction cup 3 to move downward, so that the connecting shell 31 slides down outside the blocking rod 4 until the connecting shell 31 slides to abut against the convex surface of the bottom end of the support frame 32. At this time, the top and bottom ends of the connecting suction cup 3 are both sealed structures. During the sliding of the connecting shell 31 When the replacement core is fixed, the sealing rod 41 is tightly connected to the sealing rod 4 and the rubber block 42. When the replacement core needs to be replaced, the sealing block 41 and the sealing rod 4 are pulled out from the support frame 32 and the through groove 33. At this time, the inner cavity of the connecting suction cup 3 is no longer a closed structure, so that the connection between the connecting suction cup 3 and the replacement core is released, thereby releasing the limit of the replacement core, and the replacement core can be easily taken out from the inside of the installation cavity 11 for replacement.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
