Technical Field

[0001] This utility model relates to the field of bottle cap technology, and in particular to a dustproof and sealing structure for a bottle cap connecting cap. Background Technology

[0002] Bottle caps are used to seal and protect various containers. They not only provide a seal but also prevent leakage and contamination of the contents, thus maintaining their freshness. As an important component of packaging, bottle caps play a crucial role in protecting and sealing containers.

[0003] Existing bottle caps are prone to loosening during prolonged use, which can lead to dust getting into the bottle and poor sealing.

[0004] Therefore, in response to the problem that existing bottle caps are prone to loosening during long-term use, this utility model is equipped with a sealing mechanism and a dustproof mechanism. During use, the sealing mechanism seals the device, while the dustproof mechanism prevents dust from entering the device. During the sealing and dustproofing processes, the reaction force ensures that the bottle cap and the bottle mouth remain tightly connected, thereby improving the overall service life of the device. Utility Model Content

[0005] To overcome the common problem of bottle caps loosening during prolonged use.

[0006] The technical solution of this utility model is as follows: a bottle cap connecting cap dustproof sealing structure, including a bottle body, a bottle mouth and a sealing cap, wherein the bottle mouth is provided at the upper end of the bottle body, the sealing cap is threadedly connected to the side of the bottle mouth, the sealing cap is disposed above the bottle body, a sealing mechanism is connected to the upper inner wall of the sealing cap, the sealing mechanism is disposed above the bottle mouth, and a dustproof mechanism is slidably connected to the lower end of the sealing cap, the dustproof mechanism is disposed above the bottle body.

[0007] Preferably, the sealing mechanism includes a circular shell, a slider, a sliding column, a return spring, a sealing cap, and a soft pad. The circular shell is provided at an equal angle on the upper inner side of the sealing cap. The slider is slidably connected to the inner side of the circular shell. The sliding column is connected to the lower surface of the slider. The return spring is provided inside the circular shell. The sealing cap is connected to the lower surface of the sliding column. The sealing cap is positioned above the bottle mouth. The soft pad is fixedly connected to the lower end of the sealing cap.

[0008] Preferably, the sliding column extends through the lower end of the circular shell, and the soft pad fits against the upper end of the bottle mouth.

[0009] Preferably, the upper end of the reset spring is connected to the inner upper wall of the circular shell, and the lower end of the reset spring is connected to the upper surface of the slider.

[0010] Preferably, the dustproof mechanism includes an annular groove, a dustproof ring, a housing, a circular block, a sliding rod, and a spring hook. The lower end of the sealing cap has an annular groove located above the bottle body. A dustproof ring is slidably connected to the inner side of the annular groove. The housing is connected to the upper wall of the annular groove at equal angles. A circular block is slidably connected to the inner side of the housing. A sliding rod is connected to the lower surface of the circular block. A spring hook is provided on the side of the sliding rod.

[0011] Preferably, the slide rod passes through the lower wall of the housing, the slide rod is connected to the upper surface of the dustproof ring, and the dustproof ring is fitted to the upper end of the bottle.

[0012] Preferably, the upper end of the spring hook is connected to the lower surface of the circular block, and the lower end of the spring hook is connected to the bottom surface inside the housing.

[0013] The beneficial effects of this utility model are:

[0014] 1. A sealing mechanism is provided. When the sealing cap is connected to the bottle mouth and rotates continuously, the bottle mouth squeezes the soft pad, which drives the slider and the slide column to squeeze the return spring. At the same time, the reaction force of the return spring squeezes the sealing cap and causes the soft pad to stick together, thereby sealing the bottle mouth.

[0015] 2. Equipped with a dustproof mechanism, during use, when the sealing cap is threadedly connected to the bottle mouth, the sealing cap moves the dustproof ring downwards to fit against the upper end of the bottle. As the sealing cap continues to rotate and descend, it pushes the dustproof ring down. After fitting against the upper end of the bottle, the dustproof ring slides into the annular groove. During this sliding process, it pushes the circular block and slide rod to pull the spring hook. The spring hook pulls the circular block to make the dustproof ring fit tightly against the upper end of the bottle, thus preventing dust from entering the bottle.

[0016] 3. During use, the sealing and dustproof mechanisms create contact between the bottle mouth and the bottle body, thereby ensuring a tight connection between the sealing cap and the bottle mouth. This prevents the device from becoming loose during prolonged use and extends its overall lifespan. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-2 This utility model provides a technical solution: a bottle cap connecting cap dustproof sealing structure, including a bottle body 1, a bottle mouth 2 and a sealing cap 3. The bottle mouth 2 is provided at the upper end of the bottle body 1, and the sealing cap 3 is threadedly connected to the side of the bottle mouth 2. The sealing cap 3 is located above the bottle body 1. A sealing mechanism 4 is connected to the upper inner wall of the sealing cap 3. The sealing mechanism 4 is located above the bottle mouth 2. A dustproof mechanism 5 is slidably connected to the lower end of the sealing cap 3. The dustproof mechanism 5 is located above the bottle body 1.

[0026] Please see Figures 3-4The sealing mechanism 4 includes a circular shell 41, a slider 42, a sliding column 43, a return spring 44, a sealing cap 45, and a soft pad 46. A circular shell 41 is equidistantly positioned on the upper inner side of the sealing cap 3. A slider 42 is slidably connected to the inner side of the circular shell 41. A sliding column 43 is connected to the lower surface of the slider 42. A return spring 44 is installed inside the circular shell 41. The sealing cap 45 is connected to the lower surface of the sliding column 43. The sealing cap 45 is positioned above the bottle mouth 2. A soft pad 46 is fixedly connected to the lower end of the sealing cap 45. The sliding column 43 penetrates the lower end of the circular shell 41. The pad 46 is attached to the upper end of the bottle mouth 2. The upper end of the return spring 44 is connected to the upper inner wall of the circular shell 41, and the lower end of the return spring 44 is connected to the upper surface of the slider 42. During the continuous rotation of the sealing cap 3, the bottle mouth 2 squeezes the pad 46, causing the sealing cap 45 to rise. During the rising process, the sealing cap 45 causes the slider 42 and the sliding column 43 to slide inside the circular shell 41. At the same time, the slider 42 squeezes the return spring 44 during the sliding process. Simultaneously, the reaction force of the return spring 44 squeezes the sealing cap 45, causing the pad 46 to adhere, thereby sealing the bottle mouth 2.

[0027] Please see Figures 5-6 The dustproof mechanism 5 includes an annular groove 51, a dustproof ring 52, a housing 53, a circular block 54, a sliding rod 55, and a spring hook 56. The sealing cap 3 has an annular groove 51 at its lower end, located above the bottle body 1. A dustproof ring 52 is slidably connected to the inner side of the annular groove 51. The housing 53 is connected at equal angles to the upper inner wall of the annular groove 51. A circular block 54 is slidably connected to the inner side of the housing 53. A sliding rod 55 is connected to the lower surface of the circular block 54, and a spring hook 56 is provided on the side of the sliding rod 55. 6. The sliding rod 55 passes through the lower wall of the shell 53 and is connected to the upper surface of the dustproof ring 52. The dustproof ring 52 is attached to the upper end of the bottle body 1. The upper end of the spring hook 56 is connected to the lower surface of the circular block 54, and the lower end of the spring hook 56 is connected to the inner bottom surface of the shell 53. When the sealing cap 3 is threaded onto the side of the bottle mouth 2, the sealing cap 3 drives the dustproof ring 52 to descend during the connection process, so that the dustproof ring 52 is attached to the upper end of the bottle body 1, thereby preventing dust from entering the interior of the bottle body 1.

[0028] Working principle: According to Figures 1 to 4 First, during use, the sealing cap 3 is threaded onto the side of the bottle mouth 2. As the sealing cap 3 rotates, the soft pad 46 first comes into contact with the upper end of the bottle mouth 2, thus sealing the bottle mouth 2. At the same time, as the sealing cap 3 continues to rotate, the bottle mouth 2 squeezes the soft pad 46, causing the sealing cap 45 to rise. During the rising process, the sealing cap 45 causes the slider 42 and the sliding column 43 to slide inside the circular shell 41. At the same time, the slider 42 squeezes the return spring 44 during the sliding process. Simultaneously, the reaction force of the return spring 44 squeezes the sealing cap 45, causing the soft pad 46 to come into contact, thus sealing the bottle mouth 2.

[0029] according to Figures 5 to 6When the sealing cap 3 is threaded onto the side of the bottle mouth 2, during the connection process, the sealing cap 3 drives the dustproof ring 52 to descend, so that the dustproof ring 52 fits against the upper end of the bottle body 1. At the same time, as the sealing cap 3 continues to rotate and descend, it drives the dustproof ring 52 to press down. After the dustproof ring 52 fits against the upper end of the bottle body 1, it slides into the annular groove 51, while pushing the circular block 54 and the sliding rod 55 to slide inside the shell 53. At the same time, as the circular block 54 slides, it pulls the spring hook 56, and the spring hook 56 pulls the circular block 54 to reset. This drives the circular block 54 and the sliding rod 55 to push the dustproof ring 52 to fit against the upper end of the bottle body 1, thereby preventing dust from entering the interior of the bottle body 1.

[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
