Description

Technical Field

[0001] The utility model relates to the technical field of electric mosquito repellent liquid bottles, in particular to a screw cap for an electric mosquito repellent liquid bottle. Background Art

[0002] Electric mosquito coils are mosquito repellents that work by drawing insecticide onto a sheet of paper and using heat to evaporate the insecticide. Their effectiveness typically lasts for 6-8 hours. They come in both sheet and liquid bottle versions. Sheet coils require daily replacement, while a single bottle of liquid coils provides approximately 60 days of continuous use. Liquid coils consist of a heater and a bottle. A core rod in the bottle absorbs the liquid, which is then heated and evaporated into the air. When not in use, the liquid coil is typically stored with a cap. This not only slows down evaporation and leakage, but also prevents direct contact between the coil and the liquid, especially with children. However, conventional caps simply screw onto the bottle, making them easily unscrewable by older children. This can easily expose the liquid to the coil, potentially posing a health risk to children.

[0003] Therefore, those skilled in the art provide a screw cap for an electric mosquito repellent liquid bottle to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a screw cap for an electric mosquito repellent liquid bottle, comprising a main cover body and a sub-cover body, an internal thread matched with the external thread of the electric mosquito repellent liquid bottle cap is provided on the inner side of the lower part of the main cover body, the main cover body is threadedly connected to the electric mosquito repellent liquid bottle, two latch teeth are provided at equal intervals at the step of the main cover body, and spring pieces are provided at equal intervals at the step of the main cover body, an avoidance hole is provided in the middle part of the upper end of the sub-cover body, a latch tooth is provided at the top of the inner side of the sub-cover body corresponding to the latch tooth two, the sub-cover body is sleeved on the outer side of the main cover body, and the top end of the spring piece supports the inner top of the sub-cover body.

[0005] Preferably: the main cover body includes a cover cap and an extension cap, the extension cap is integrally provided at the middle part of the upper end of the cover cap, the inner side of the cover cap is provided with an internal thread matching the external thread of the bottle mouth, the cover cap is threadedly connected to the bottle mouth of the electric mosquito repellent liquid bottle, the core rod in the middle of the electric mosquito repellent liquid bottle is located in the extension cap, and two latch teeth are evenly spaced on the top edge of the cover cap, a fixing block is provided on the inner side of the second latch tooth at the top of the cover cap, and a spring piece is fixed on the top of the fixing block.

[0006] Preferably, the first latching tooth and the second latching tooth are triangular tooth structures.

[0007] Preferably, the spring pieces are of a curved elastic metal sheet structure, and two spring pieces are relatively fixedly arranged on a fixed block.

[0008] Preferably: a limiting flange is fixedly provided around the lower outer side of the cap, and a limiting groove is provided at the lower inner side of the sub-cover body corresponding to the limiting flange. The limiting groove is an annular groove, and the limiting flange is located in the limiting groove. The position of the sub-cover body moving up and down is limited by the limiting flange and the limiting groove, preventing the sub-cover body from easily slipping off the main cover body.

[0009] The technical effects and advantages of this utility model are:

[0010] 1. The top end of the spring sheet provided in the utility model supports the inner top of the sub-cover body. When no external force is applied, the spring sheet pushes up the sub-cover body, and the first latch tooth and the second latch tooth are not in contact. At this time, when the sub-cover body is rotated, it can only be rotated relative to the main cover body, and the main cover body does not rotate. In this way, the main cover body cannot be easily rotated away from the electric mosquito repellent liquid bottle. Even if a child gets the electric mosquito repellent liquid bottle, it is difficult to open it, which can effectively ensure the safety of the use of the electric mosquito repellent liquid and has a certain protective effect on children.
