All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0016] like Figure 1 As shown, this utility model provides an antibacterial isolation device for bottled drinking water, including an isolation upper cover, an isolation lower cover, and a blocking ball 7 disposed at the bottle mouth; The isolation cover includes an upper cover plate 1 and an upper cover side panel 2, with the top edge of the upper cover side panel 2 fixedly connected to the bottom edge of the upper cover plate 1. The lower isolation cover includes a lower cover plate 3 and a lower cover side panel 4. The bottom edge of the lower cover side panel 4 is fixedly connected to the top edge of the lower cover plate 3. Both the upper isolation cover and the lower isolation cover are integrally formed covers with no seams between the cover plate and the side panel, which can prevent water leakage.
[0017] The bottom of the upper cover side panel 2 and the bottom of the lower cover side panel 4 are connected accordingly. The inner side of the upper cover side panel 2 is provided with an internal thread 8, and the outer side of the lower cover side panel 4 is provided with an external thread 9 that matches the internal thread 8. The two can be spirally connected by the internal thread 8 and the external thread 9 to achieve the connection and installation of the upper and lower cover. Other spiral structures can also be used, such as providing corresponding male and female rotating buckles on the upper and lower cover side panels.
[0018] like Figure 2 As shown, the upper cover plate 1 has a through-hole 5, which is a mesh outlet 5. The center of the upper cover plate 1 is a solid plate, and the edge of the upper cover plate 1 is a mesh plate, wherein the mesh of the mesh plate forms the outlet 5. In this utility model, it is designed as multiple fan-shaped grid-like outlets, which has an aesthetic effect.
