Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust caps, in particular to a straw dust cap. Background Art
[0002] A dust cap generally refers to a cap structure sleeved at a specific position to achieve a dust-proof effect.
[0003] Since it is inconvenient for infants and young children to drink water, they usually use a straw to assist in drinking water. However, since one end of the straw exposed to the external environment is an open structure, there are potential hazards of crawlers entering the straw and dust falling on the pipe orifice. Therefore, a dust cap is used to eliminate the hazards. However, the traditional dust cap has a fixed size and can only be adapted to the dust prevention of a straw of one size. Therefore, the adaptability of this kind of dust cap is poor.
[0004] Based on this, a straw dust cap is proposed. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a straw dust cap to solve the above problems.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A straw dust cap includes a cap cover. An inner cavity is formed in the cap cover. A limiting ring is connected to the inner wall of the inner cavity. There are a plurality of the limiting rings, and the plurality of limiting rings are connected to the inner wall of the inner cavity at equal intervals up and down. A plugging cone is connected to the center of the bottom end of the inner cavity. A decoration mechanism for decorating the dust cap is connected to the outside of the cap cover.
[0008] Preferably, a connecting rod is connected to one side of the cap cover, and a silica gel ring is connected to the other end of the connecting rod.
[0009] Preferably, the decoration mechanism includes a decoration doll, and the decoration doll is connected to one side of the cap cover.
[0010] Preferably, a connection hole and a connection cavity are formed in the cap cover. A filling disc is connected to one side of the decoration doll through a connection column.
[0011] Preferably, the filling disc and the connection cavity are mutually fitted, and the connection column is connected to the connection hole.
[0012] In summary, due to adopting the above technical scheme, the beneficial effects of the utility model are as follows:
[0013] 1. By adopting the plugging cone structure, the utility model uses the plugging cone to block the straw. The conical structure can be adapted to straws of any size. Cooperating with the limiting rings arranged on one side, the firmness of the dust cap assembled on the straw is improved.
[0014] 2. By adopting the silicone ring structure, the dust-proof cover of the present application can be sleeved on straws of any size using the silicone ring. Since the silicone ring is made of silicone material, it has good structural elasticity and adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-3 , the present utility model provides a technical solution:
[0022] A straw dust-proof cap includes a cap 1. An inner cavity 4 is provided on the cap 1. A limiting ring 5 is connected to the inner wall of the inner cavity 4. There are multiple limiting rings 5, and the multiple limiting rings 5 are connected to the inner wall of the inner cavity 4 at equal intervals up and down. By setting the limiting ring 5, it is avoided that the cap 1 shakes when installed on the straw, improving the stability of the installation. The center of the bottom end of the inner cavity 4 is connected with a plugging vertebral body 6. The plugging vertebral body 6 adopts a conical structure, so as to adapt to straws with different inner diameters, improving the applicability of the dust-proof cap. A decorative mechanism for decorating the dust-proof cap is connected to the outside of the cap 1. The overall structure of the dust-proof cap is made of silicone material, meeting the straw use standard, and the structure of the decorative doll 7 can adopt non-silicone materials according to actual use requirements, thereby reducing production costs.
[0023] Specifically, as Figure 1As shown in the figure, one side of the cap 1 is connected with a connecting rod 2, and the other end of the connecting rod 2 is connected with a silicone ring 3. By adopting the structure of the silicone ring 3 with good elasticity, the silicone ring 3 can be sleeved outside the straw with any diameter.
[0024] Specifically, as Figure 1 shown in the figure, the decoration mechanism includes a decoration doll 7, and the decoration doll 7 is connected to one side of the cap 1. The setting of the decoration doll 7 increases the aesthetic degree of use, and different decoration dolls 7 can be adapted to different user groups, making the structure of the dust-proof cap diverse and convenient to distinguish.
[0025] Specifically, as Figure 3 shown in the figure, a connection hole 8 and a connection cavity 9 are opened on the cap 1. One side of the decoration doll 7 is connected with a filling plate 11 through a connecting column 10. By setting the connection hole 8 and the connection cavity 9, the structure of the decoration doll 7 is detachable, meeting the diverse usage requirements of users.
[0026] Specifically, as Figure 3 shown in the figure, the filling plate 11 and the connection cavity 9 fit each other, and the connecting column 10 is connected to the connection hole 8. By setting the filling plate 11, it is ensured that when the decoration doll 7 is installed, it is stably connected to the outside of the cap 1, and the structures are not easily separated from each other, and at the same time, the replacement convenience is improved.
[0027] In summary, for the straw dust-proof cap provided in this embodiment, when installing the dust-proof cap, first buckle the silicone ring 3 on the straw, and then dock the cap 1 at the upper end of the straw, and ensure that the plugging cone 6 is docked into the straw nozzle. According to the different inner diameters of the straw, the docking depth of the cap 1 is different. When the inner diameter of the straw is thicker, the buckling depth of the plugging cone 6 is deeper, and vice versa, the buckling depth is shallower. At this time, the inner wall of the cap 1 does not necessarily fit the outside of the straw. Add a limiting ring 5, thereby increasing the probability that the limiting ring 5 abuts against the outside of the straw, ensuring stable docking between the dust-proof cap and the straw;
[0028] Among them, the decoration doll 7 connected to the outside of the cap 1, due to the use of a movable connection method, enables the decoration doll 7 to be replaced at will, improving the diversity of the dust-proof cap structure and being more adaptable to different user groups.
[0029] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
