[0039] Example 1

[0040] like Figure 1-6 As shown, an embodiment of the present invention provides a bottle cap structure, which includes an inner cap 1 and an outer cap 2; the inner cap 1 is screwed with the bottle mouth 31 of the liquid storage bottle 3 along a first circumferential direction, and is unlocked with the bottle mouth 31 along a second circumferential direction; the outer cap 2 is disposed outside the inner cap 1, and a locking structure is provided between the inner cap 1 and the outer cap 2;

[0041] Among them, when the outer cover 2 is rotated along the first circumferential direction or force is applied to the direction of the liquid storage bottle 3 and the outer cover 2 is rotated along the second circumferential direction, the locking structure can lock the inner cover 1 and the outer cover 2; when the outer cover 2 is rotated only along the second circumferential direction, the locking structure can separate the outer cover 2 from the inner cover 1 along the axial direction.

[0042] In this embodiment, the bottle cap structure includes an inner cap 1 and an outer cap 2; the inner cap 1 is screwed with the bottle mouth 31 of the liquid storage bottle 3 along a first circumferential direction, and is unlocked with the bottle mouth 31 along a second circumferential direction; the outer cap 2 is disposed outside the inner cap 1, and a locking structure is provided between the inner cap 1 and the outer cap 2;

[0043] When the outer cover 2 is rotated in the first circumferential direction, the inner cover 1 can be screwed into the bottle mouth 31 of the liquid storage bottle 3;

[0044] Or when a force is applied toward the liquid storage bottle 3 and the outer cover 2 is rotated in the second circumferential direction, the locking structure can lock the inner cover 1 and the outer cover 2, and at this time, the inner cover 1 and the bottle mouth 31 of the liquid storage bottle 3 can be unlocked;

[0045] When the outer cover 2 is rotated only along the second circumferential direction, the locking structure can separate the outer cover 2 from the inner cover 1 along the axial direction. At this time, the inner cover 1 cannot be unlocked from the bottle mouth 31 of the liquid storage bottle 3. Therefore, the bottle cap structure of this embodiment has a child lock function, which prevents children from easily unscrewing the bottle cap, causing the atomized liquid to leak or be accidentally ingested by children, thereby improving the safety of the product.

[0046] In some embodiments, the locking structure includes a locking groove 11 configured at an end of the inner cover 1 away from the liquid storage bottle 3 and a locking protrusion 21 configured on the inner wall of the outer cover 2 facing the liquid storage bottle 3 and extending toward the liquid storage bottle 3, wherein the locking protrusion 21 is located in the locking groove 11, and the locking groove 11 has a first side wall 111 and a second side wall 112 in sequence along a first circumferential direction, and the second side wall 112 is parallel to the extension direction of the locking protrusion 21;

[0047] The first side wall 111 is arranged at a preset angle with the extending direction of the locking protrusion 21 , and the preset angle is greater than 0° and less than 180°; or, the first side wall 111 is an arcuate surface tangent to the extending direction of the locking protrusion 21 .

[0048] The locking structure of this embodiment includes a locking groove 11 configured at one end of the inner cover 1 away from the liquid storage bottle 3 and a locking protrusion 21 configured at the inner wall of the outer cover 2 facing the liquid storage bottle 3 and extending toward the liquid storage bottle 3. The locking protrusion 21 is located in the locking groove 11. The locking groove 11 has a first side wall 111 and a second side wall 112 in sequence along a first circumferential direction. The second side wall 112 is parallel to the extending direction of the locking protrusion 21. Therefore, when the outer cover 2 is rotated along the first circumferential direction, the inner cover 1 can be screwed with the bottle mouth 31 of the liquid storage bottle 3.

[0049] The first side wall 111 is arranged at a preset angle with the extending direction of the locking protrusion 21, and the preset angle is greater than 0° and less than 180°; or, the first side wall 111 is an arc-shaped surface tangent to the extending direction of the locking protrusion 21;

[0050] Therefore, when a force is applied toward the liquid storage bottle 3 and the outer cover 2 is rotated in the second circumferential direction, the locking structure can lock the inner cover 1 and the outer cover 2, and at this time, the inner cover 1 and the bottle mouth 31 of the liquid storage bottle 3 can be unlocked;

[0051] When the outer cover 2 is rotated only along the second circumferential direction, the locking structure can separate the outer cover 2 from the inner cover 1 along the axial direction. At this time, the inner cover 1 cannot be unlocked from the bottle mouth 31 of the liquid storage bottle 3. Therefore, the bottle cap structure of this embodiment has a child lock function, which prevents children from easily unscrewing the bottle cap, causing the atomized liquid to leak or be accidentally ingested by children, thereby improving the safety of the product.

[0052] In some embodiments, the inner cover 1 is configured with a tubular cover portion 12 extending toward the outer cover 2 at one end away from the liquid storage bottle 3, and the locking grooves 11 and the locking protrusions 21 are both multiple and correspond one to one. The multiple locking protrusions 21 are evenly distributed along the circumferential direction on the radially outer side of the tubular cover portion 12. The locking grooves 11 and the locking protrusions 21 of this embodiment are both multiple and correspond one to one, which improves the locking effect of the locking structure and prevents slipping between the inner cover 1 and the outer cover 2 when locking.

[0053] In some embodiments, the locking structure includes a locking protrusion 21 configured at one end of the inner cover 1 away from the liquid storage bottle 3 and extending toward the outer cover 2, and a locking groove 11 configured at the outer cover 2 toward the inner wall of the liquid storage bottle 3, wherein the locking protrusion 21 is located in the locking groove 11, and the locking groove 11 has a first side wall 111 and a second side wall 112 in sequence along a first circumferential direction, and the second side wall 112 is parallel to the extension direction of the locking protrusion 21;

[0054] The first side wall 111 is arranged at a preset angle with the extending direction of the locking protrusion 21 , and the preset angle is greater than 0° and less than 180°; or, the first side wall 111 is an arcuate surface tangent to the extending direction of the locking protrusion 21 .

[0055] The locking structure of this embodiment includes a locking protrusion 21 configured at one end of the inner cover 1 away from the liquid storage bottle 3 and extending toward the outer cover 2, and a locking groove 11 configured at the inner wall of the outer cover 2 facing the liquid storage bottle 3. The locking protrusion 21 is located in the locking groove 11. The locking groove 11 has a first side wall 111 and a second side wall 112 in sequence along a first circumferential direction. The second side wall 112 is parallel to the extension direction of the locking protrusion 21. At this time, the inner cover 1 can be screwed with the bottle mouth 31 of the liquid storage bottle 3.

[0056] The first side wall 111 is arranged at a preset angle with the extension direction of the locking protrusion 21, and the preset angle is greater than 0° and less than 180°; or, the first side wall 111 is an arc-shaped surface tangent to the extension direction of the locking protrusion 21;

[0057] Therefore, when a force is applied toward the liquid storage bottle 3 and the outer cover 2 is rotated in the second circumferential direction, the locking structure can lock the inner cover 1 and the outer cover 2, and at this time, the inner cover 1 and the bottle mouth 31 of the liquid storage bottle 3 can be unlocked;

[0058] When the outer cover 2 is rotated only along the second circumferential direction, the locking structure can separate the outer cover 2 from the inner cover 1 along the axial direction. At this time, the inner cover 1 cannot be unlocked from the bottle mouth 31 of the liquid storage bottle 3. Therefore, the bottle cap structure of this embodiment has a child lock function, which prevents children from easily unscrewing the bottle cap, causing the atomized liquid to leak or be accidentally ingested by children, thereby improving the safety of the product.

[0059] In some embodiments, the inner cover 1 is configured with a tubular cover portion 12 extending toward the outer cover 2 at one end away from the liquid storage bottle 3, and the locking grooves 11 and the locking protrusions 21 are both multiple and correspond one to one. The multiple locking grooves 11 are evenly distributed along the circumferential direction on the radially outer side of the tubular cover portion 12. The locking grooves 11 and the locking protrusions 21 of this embodiment are both multiple and correspond one to one, which improves the locking effect of the locking structure and prevents slipping between the inner cover 1 and the outer cover 2 when locking.

[0060] In some embodiments, a liquid injection tube 4 is inserted into the mouth of the liquid storage bottle 3 , and the liquid injection tube 4 is located in the tubular cover portion 12 . The inner wall of the tubular cover portion 12 is configured with a sealing protrusion 121 inserted into the liquid injection tube 4 .

[0061] In some embodiments, the locking groove 11 radially penetrates from the outer wall of the tubular cover portion 12 to the outer wall of the inner cover 1 .

[0062] In some embodiments, the outer periphery of the bottle mouth 31 is configured with an external thread, and the inner wall of the inner cover 1 is configured with an internal thread that matches the external thread.

[0063] In some embodiments, the locking protrusion 21 is a long strip structure, and the cross section is rectangular or square.
