Abstract
Description
Technical Field
[0001] This utility model relates to the field of perfume spray head technology, specifically a perfume spray head based on an inner plug double-layer sealing structure. Background Technology
[0002] As is well known, in traditional perfume bottle designs, the connection between the spray nozzle and the bottle body typically relies on simple threaded connections or snap-fit structures. However, most traditional perfume spray nozzles use a single sealing mechanism, such as a simple rubber ring or gasket, to achieve a seal. This single-layer seal design often fails to provide sufficient sealing protection when faced with temperature changes, pressure fluctuations, and prolonged use, easily leading to perfume leakage or fragrance dissipation. This not only affects the quality and longevity of the perfume but may also cause user dissatisfaction. Since perfumes are often carried around, they inevitably encounter external forces such as collisions and vibrations during transportation or use. Traditional connection methods may not be secure enough in such situations, easily causing the spray nozzle to loosen or even detach, seriously affecting the user experience and potentially resulting in perfume waste. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model provides a perfume spray nozzle based on an inner plug double-layer sealing structure, which has the following beneficial effects:
[0016] This perfume spray head, based on an inner double-layer sealing structure, effectively enhances the seal between the spray head and the bottle by employing a first and second sealing ring. This not only ensures the perfume's airtight preservation under normal conditions but also withstands environmental factors such as temperature changes and pressure fluctuations, preventing leakage or fragrance loss. Due to the significantly improved sealing performance, the perfume can maintain its original fragrance and quality during long-term storage, avoiding deterioration or evaporation loss caused by poor sealing, thus extending the perfume's shelf life. When the spray head is threaded onto the bottle, the fastening post loosens, and the elastic component's supporting toothed plate enters the annular groove and engages with the toothed ring, forming a secure lock. This enhances the spray head's stability on the bottle, preventing it from easily loosening even under shaking or impact. It effectively prevents the risk of the spray head loosening due to accidental impacts or vibrations during daily use, ensuring the spray head always fits tightly against the bottle and maintains a good seal.

[0022] 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.
[0023] Please see Figure 1-4This utility model relates to a perfume spray head based on a double-layer sealing structure with an inner plug, comprising a bottle body 1 and a spray head body 2. The spray head body 2 has a first sealing ring 3 and a sealing cap 4 arranged sequentially from bottom to top. The top of the spray head body 2 has an annular groove and a threaded hole, and the spray head body 2 is threadedly connected to the threaded hole. A toothed ring 5 is provided on the outer ring of the annular groove. A second sealing ring 6 is provided at the bottom of the sealing cap 4. An adjustment groove is provided at the bottom of the sealing cap 4, and a fastening groove is provided on one side of the top of the adjustment groove. A fastening hole is provided between the outer side of 4 and the fastening groove. A fastening post 7 is provided on the fastening hole. A toothed plate 8 is provided between the fastening post 7 and the adjusting groove. The toothed plate 8 engages with the toothed ring 5. An elastic member 9 is provided between the toothed plate 8 and the fastening groove. A guide mechanism is provided between the toothed plate 8 and the adjusting groove. In this embodiment, the nozzle body 2 is threaded onto the bottle body 1 through a threaded hole. At the same time, the fastening post 7 is pushed. The fastening post 7 moves linearly in the fastening hole, causing the toothed plate 8 to move, thereby allowing the toothed plate 8 to move in... As the nozzle moves within the adjusting groove, the elastic component 9 in the fastening groove is compressed and deformed. When the nozzle body 2 is threaded into the threaded hole, the sealing cap 4 rests against the top of the bottle body 1. At this time, the first sealing ring 3 rests against the top of the threaded hole, and the second sealing ring 6 rests against the top of the bottle body 1. The bottom end of the toothed plate 8 is exactly aligned with the toothed ring 5 in the annular groove. By loosening the fastening post 7, the elastic component 9 elastically supports the toothed plate 8, and the toothed plate 8 moves linearly within the adjusting groove. The toothed plate 8 can engage with the toothed ring 5 on the annular groove, thereby locking the sealing cap 4 in place. This design ensures that the nozzle body 2 is securely and reliably fixed to the bottle body 1, preventing loosening due to shaking or other factors. This improves the stability and reliability of the nozzle body 2 on the bottle body 1. The first sealing ring 3 and the second sealing ring 6 achieve a double-layer seal between the nozzle body 2 and the bottle body 1, ensuring that the perfume and odor do not leak, further enhancing the sealing stability. When it is necessary to remove the nozzle body 2, simply push the fastening post 7 to disengage the toothed plate 8 from the toothed ring 5, and then rotate the nozzle body 2 to remove it from the threaded hole. This design is convenient to use.
[0024] In this solution, the guiding mechanism includes a slide groove and a slider 10. The slide groove is opened on one side of the adjustment groove. The slider 10 is located in the slide groove and connected to the toothed plate 8. When the toothed plate 8 moves, it drives the slider 10 to move. The slider 10 slides linearly in the slide groove, thereby enabling the toothed plate 8 to move more stably in a linear direction and engage against the toothed ring 5.
[0025] In this solution, two guide mechanisms are provided and symmetrically arranged. The linear movement stability of the toothed plate 8 can be further improved by using two symmetrically arranged guide mechanisms.
[0026] In this design, both the groove and the slider 10 are T-shaped. The T-shaped slider 10 and the groove can improve the linear movement stability of the slider 10 in the groove.
[0027] In this design, the elastic component 9 is an alloy spring, which has excellent elasticity and recovery ability, and can support the toothed plate 8 more stably.
[0028] In this solution, both the first sealing ring 3 and the second sealing ring 6 are made of high and low temperature resistant rubber material, which can be used to achieve a normal sealing effect in hot and low temperature weather.
[0029] In this solution, the fastening post 7 is provided with a handle 11, which makes it easy to hold and use the fastening post 7 by holding the handle 11.
[0030] In this design, the sealing cap 4 is made of polypropylene, a lightweight, durable thermoplastic with excellent chemical stability. It resists the erosion of many chemicals, including those in perfumes, and can be reliably used on perfume bottles.
[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.
