Description

Technical Field

[0001] This utility model relates to the field of sealing technology for electric mosquito repellent liquid bottles, specifically to a sealing cap for fixing an electric mosquito repellent liquid evaporation rod. Background Technology

[0002] Electric mosquito repellents are mosquito-repelling devices that work by absorbing insecticide into a paper pad, which is then evaporated by heat. The effect typically lasts 6-8 hours. Electric mosquito repellents come in two types: tablets and liquid bottles. Tablet repellents need to be replaced daily, while a single bottle of liquid repellent can last approximately 60 days. Liquid bottle repellents consist of a heater and a sealing bottle. The wick in the sealing bottle absorbs the mosquito repellent liquid, which is then heated and evaporated into the air by the heater.

[0003] The mandrel is usually positioned at the bottle opening with a positioning plug to ensure that the mandrel is positioned on the central axis of the bottle. However, once the positioning plug is inserted into the bottle opening, it is inconvenient to remove it, which makes it inconvenient to add liquid to the bottle.

[0004] Therefore, those skilled in the art have provided a method for fixing and sealing the electric mosquito repellent liquid evaporation stick to solve the problems mentioned in the background art. Utility Model Content

[0005] To solve the above technical problems, this utility model provides a sealing cap for fixing the evaporating rod of electric mosquito repellent liquid, including a main positioning plug. The main positioning plug is tightly inserted into the mouth of the electric mosquito repellent liquid bottle. A downward-facing blind hole is formed in the middle of the main positioning plug. A through hole is formed at the center of the bottom of the blind hole. The through hole is a conical hole. A secondary positioning plug is placed inside the through hole. The outer surface of the secondary positioning plug is a tapered surface that mates with the through hole. The secondary positioning plug is made of rubber. A second through hole is formed in the center of the secondary positioning plug. An evaporating rod is inserted into the second through hole and can slide relative to the second through hole. A pressure cap is threaded inside the blind hole. One part of the through hole at the bottom of the blind hole on the main positioning plug 1 protrudes upwards, increasing... The inner surface area of ​​the through hole is increased; an upward-facing clearance hole 5 is opened at the bottom of the pressure cap 2, which is used to avoid the upward protrusion at the bottom of the blind hole of the main positioning plug 1 and the upper part of the secondary positioning plug 4, so that the lower end of the pressure cap 2 can rotate normally to the bottom of the blind hole on the main positioning plug 1; a central hole is opened at the center of the pressure cap 2 for the upper part of the evaporating rod to pass through, and a stepped hole is opened downward along the through hole on the upper part of the pressure cap 2. A protective cover 3 is installed inside the step, and the protective cover 3 is located on the outside of the evaporating core rod; an internal thread is opened on the inner side of the stepped hole on the pressure cap 2, and an external thread is opened on the lower outer side of the protective cover 3. The protective cover 3 is connected to the internal thread of the stepped hole on the pressure cap 2 through the external thread.

[0006] The technical effects and advantages of this utility model are as follows:

[0007] 1. The blind hole internal threaded connection cap of this utility model, when rotated downward, compresses the secondary positioning plug downward. The secondary positioning plug is squeezed by the first through hole, and the second through hole on the secondary positioning plug contracts tightly to squeeze the evaporating rod, making it difficult for the evaporating rod to move. Rotating the cap upward removes the secondary positioning plug, and the secondary positioning plug is in a relaxed state. Pulling the evaporating rod upward allows the evaporating rod and the secondary positioning plug to be easily pulled out. The liquid can be replenished into the electric mosquito repellent liquid bottle through the first through hole, making it convenient for continuous use of the mosquito repellent liquid bottle. This eliminates the need for frequent replacement of the mosquito repellent liquid bottle, reduces resource waste, and plays a role in protecting the environment, which is in line with the concept of green environmental protection.

[0008] 2. The pressure cap of this utility model has a central hole for the upper part of the vaporizing rod to pass through. The upper part of the pressure cap has a stepped hole along the through hole downwards. A protective cover is installed inside the step. The protective cover is located on the outside of the vaporizing core rod, which can effectively reduce the evaporation and leakage of mosquito repellent liquid. Attached Figure Description

[0017] Example 1

[0018] Please see Figures 1-5 This embodiment provides a sealing cap for fixing the evaporating rod of electric mosquito repellent liquid, including a main positioning plug 1. The main positioning plug 1 is tightly inserted into the mouth of the electric mosquito repellent liquid bottle. A downward-facing blind hole is opened in the middle of the main positioning plug 1, and a through hole is opened at the center of the bottom end of the blind hole. The through hole is a conical hole, and a secondary positioning plug 4 is set in the through hole. The outer surface of the secondary positioning plug 4 is a tapered surface that mates with the through hole. The secondary positioning plug 4 is made of rubber. A second through hole is opened in the center of the secondary positioning plug 4, and an evaporating rod is inserted in the second through hole. The evaporating rod can slide relative to the second through hole. A pressure cap is threaded inside the blind hole. 2. Rotate the cap 2 downwards. The lower part of the cap 2 presses down on the secondary positioning plug 4. The secondary positioning plug 4 is squeezed by the through hole 1. The through hole 2 on the secondary positioning plug 4 contracts tightly and squeezes the evaporator rod. The evaporator rod is not easily moved. Rotate the cap 2 upwards to remove it. The secondary positioning plug 4 is in a relaxed state. Pull the evaporator rod upwards. You can easily pull out the evaporator rod and the secondary positioning plug 4.
