DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model more clear and obvious, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0028] The utility model discloses a kind of flow guide nozzle structures with reflux function, which is seamlessly adapted to various liquid containers by its excellent design concept and high universality. Whether in the field of daily beverage packaging, or in the chemical raw material storage container in industrial production, it can show strong practical value. From the structure application form, the flow guide nozzle 1 structure can be ingeniously used as the indispensable component of container cover, cooperates with container cover, realizes integrated convenient operation;It can also be directly integrated on the container by advanced manufacturing process, so as to provide efficient solution for the accurate pouring of liquid in container. In order to make the technical content of the utility model more easily understood, this paper will take the application of the flow guide nozzle 1 structure on bottle cap as a typical example, and expand specific and detailed elaboration. But it needs to be particularly emphasized that in actual application scene, the applicability of this structure is extremely extensive, not limited to bottle cap this specific carrier, whether the plastic bottle, glass bottle of different shapes, or various industrial large liquid storage tanks, etc. Liquid container can be easily adapted.

[0029] According to the drawings Figure 1 , 2As can be seen from the clear structure diagram shown in Figs. 1 to 3, it is not difficult to find that the structure of the flow guide nozzle 1 mainly consists of two core parts, namely the flow guide nozzle 1 and the mounting seat. As a key component for guiding liquid flow, the flow guide nozzle 1 is installed on the mounting seat in a flexible rotating manner with the aid of a precisely designed rotating support seat 3. The mounting seat plays a crucial role in the overall structure system. It can become an organic component of the container body structure through precise manufacturing process, and can also serve as a core component of the container cover 18 and cooperate with the cover 18. The core function of the mounting seat is to provide a stable and reliable mounting base for the flow guide nozzle 1, so as to ensure that the flow guide nozzle 1 will not shake or displace during use. At the same time, the structure design of the mounting seat also fully considers the rotating requirement of the flow guide nozzle 1. Through reasonable mechanical design and structure layout, it is ensured that the flow guide nozzle 1 can flexibly rotate within a certain angle range, so as to meet the diversified requirements for liquid pouring angle in different use scenarios.

[0030] In combination with the accompanying drawings Figures 4 to 7 A set of liquid return channels 4 is specially designed on the flow guide nozzle 1, and the core design purpose is to efficiently recover the liquid remaining on the surface and inside the flow guide nozzle 1 after pouring, so as to effectively avoid the problems of waste and pollution caused by liquid residue. In order to realize this precise recovery function, the liquid return port 19 of the liquid return channel 4 is precisely set outside the flow outlet 5 of the flow guide nozzle 1 through careful design. Specifically, the flow guide nozzle 1 is provided with two key openings. The opening located at the top of the flow guide nozzle 1 is defined as the flow outlet 5, which undertakes the important responsibility of precisely guiding the liquid in the container to the outside of the container. The other opening is in seamless communication with the inside of the container and is called the flow inlet 6, which provides a smooth channel for the liquid in the container to flow into the flow guide nozzle 1. It is worth mentioning that the structure design of the flow guide nozzle 1 shows high flexibility and diversity. Under the conventional design idea, a simple and practical flat pipe body structure can be adopted. The cross-sectional shape of the pipe body can be flexibly selected as circular, rectangular or other irregular shapes according to actual use requirements. At the same time, the size of the pipe cross section can also be optimized from bottom to top according to the parameters such as the flow rate and flow of the liquid. In addition, the present application fully compatible with various special forms in the existing design, for example, setting a specific radius on the inner wall of the flow guide nozzle 1, optimizing the liquid flow path by using the principle of fluid mechanics, and improving the flow efficiency; or designing the flow outlet 5 into a hawk-shaped, oblique cutout or other special shape to meet the pouring requirements of different liquid characteristics (such as high-viscosity liquid, volatile liquid, etc.). It can be said that the present application has an open and inclusive attitude towards the specific structure form of the flow guide nozzle 1, covering all known existing design forms at present, fully embodying the forward-looking and universality of its technology.

[0031] The liquid return flow channel 4 is further subdivided into a liquid return port 19 and a liquid outlet port 20. The liquid return port 19 is ingeniously arranged below the side of the flow outlet 5 of the flow guide nozzle 1 close to the liquid outflow side, and this position design can maximize the capture of the liquid remaining on the outer wall of the flow guide nozzle 1 during the pouring process. The liquid outlet port 20 is precisely arranged on the other side of the flow guide nozzle 1 facing away from the liquid outflow direction, and the two are respectively located on both sides of the flow guide nozzle 1 and present an up-down staggered layout form in position. This carefully designed layout can fully utilize the gravity of the liquid and the guiding effect of the flow channel, efficiently guide the residual liquid back to the container, realize the recycling of the liquid, and reduce waste. In order to ensure smooth communication with the inside of the container, the liquid inlet 6 and the liquid outlet port 20 are both arranged on the bottom of the rotating support seat 3. Through this ingenious structural design, the entire reflux system can realize efficient recycling function without any negative impact on the original structure of the container and the normal pouring of the liquid.

[0032] Further combined with the accompanying Figure 3 、 8 , 9, the mounting seat is specially provided with a mounting groove 2 for mounting the rotating support seat 3, and the mounting groove 2 is also carefully provided with a liquid passing port 7. This design detail seems simple, but it contains a subtle technical concept. When the rotating support seat 3 and the mounting groove 2 are rotated to the first position of the flow guide nozzle 1 under the operation of the user, the flow guide nozzle 1 is in the storage state, and at this time the entire structure enters the liquid recycling mode. In this mode, the liquid outlet port 20 and the liquid inlet 6 are in precise communication with the liquid passing port 7, so that the liquid remaining in and outside the flow guide nozzle 1 can flow back to the inside of the container through the liquid passing port 7 under the action of gravity, completing the liquid recycling process. When the rotating support seat 3 and the mounting groove 2 are rotated to the second position of the flow guide nozzle 1, the structure switches to the liquid pouring function mode. In this mode, the liquid inlet 6 is in rapid communication with the liquid passing port 7, and the liquid outlet port 20 is in close contact with the inner wall of the mounting groove 2 through ingenious structural design, and is in a completely closed state. In this way, during the liquid pouring process, the liquid can flow out smoothly along the preset flow channel from the liquid inlet 6 through the flow outlet 5 of the flow guide nozzle 1, effectively avoiding the phenomenon of liquid returning into the reflux flow channel, ensuring the smoothness and stability of the liquid pouring process.

[0033] The specific implementation is as follows: in the first position, the liquid outlet 20 is in precise communication with the liquid passage 7, guiding the smooth return of the residual liquid to the inside of the container; at the same time, the liquid inlet 6 is partially communicated with the liquid passage 7 to form a small hole, and this small hole design is ingenious, which provides a slow return channel for the residual liquid in the inside of the flow guide nozzle 1, avoiding the problem of liquid splashing caused by too fast return speed. In the second position, the liquid inlet 6 is completely overlapped and communicated with the liquid passage 7 to open up a wide and smooth main channel for liquid pouring; while the liquid outlet 20 is tightly closed with the inner wall of the mounting groove 2, completely eliminating the possibility of liquid entering the return flow channel, thereby ensuring the efficiency, stability and smoothness of the liquid pouring process in all directions. In a representative embodiment, the liquid return channel 4 adopts an innovative arrangement around the flow guide nozzle 1, the liquid return port 19 is located below the liquid outlet 5 of the flow guide nozzle 1 on the side opposite to the liquid outlet direction, and the liquid outlet 20 is located on the side opposite to the liquid outlet direction. This ring design can guide the residual liquid on the outer wall of the flow guide nozzle 1 to the back of the flow guide nozzle 1 in all directions without dead angle. More ingeniously, by arranging only one liquid passage 7 in the mounting groove 2, the liquid in the flow guide nozzle 1 and the liquid return channel 4 can be recovered at the same time, and the liquid outlet 20 is effectively closed when the flow guide nozzle 1 is opened. The design principle is simple and easy to understand and implement, and the implementation is simple and efficient, which not only greatly facilitates the process simplification and cost control in the production and processing process, but also significantly improves the stability and reliability of the product, reduces the maintenance cost in the later period.

[0034] When the cross section of the flow guide nozzle 1 is circular, the liquid guiding effect in the liquid guiding process reaches the best state, the liquid flow is more smooth, and the resistance and turbulence phenomenon of the liquid in the flow channel can be effectively reduced, and the efficiency and accuracy of the liquid pouring can be improved. When the length of the flow guide nozzle 1 is repeatedly optimized and set to 3cm, and the total height of the flow guide nozzle 1 and the rotating support seat 3 is accurately controlled to 4.5cm, the liquid pouring and return effect reaches the optimal level. Under this parameter combination, whether it is the pouring speed, flow control of liquid, or the recovery efficiency of residual liquid, an ideal balance state can be achieved, bringing the user an extreme use experience.

[0035] In a typical embodiment of practical application, the flow guide nozzle 1 is precisely installed on the cover 18, which is the bottle cap body commonly seen in our daily life. The top of the cover 18 is specially designed with a protruding storage groove 8, which is of great significance. Its main function is to store the flow guide nozzle 1 and prevent it from being exposed and accumulating dust when idle, affecting the product's hygiene and performance. One side of the storage groove 8 is provided with a through-going accommodation opening 9 from top to bottom, which provides sufficient space and convenient access for the rotation of the flow guide nozzle 1. When the flow guide nozzle 1 is turned out of the accommodation opening 9, it will naturally assume an inclined state, and at this time the outlet 5 is located outside the storage groove 8, creating excellent conditions for liquid flow and facilitating smooth liquid flow. The installation groove 2 is located at the bottom of the storage groove 8 and is used to install the rotating support seat 3. The bottom surface of the installation groove 2 is carefully designed to be arc-shaped, and the bottom surface of the rotating support seat 3 is also arc-shaped and closely fitted therewith. The two sides of the installation groove 2 are provided with first shaft holes 11, and the rotating support seat 3 is provided with a matching first rotating shaft 12. The rotating support seat 3 is installed in the installation groove 2 through the first rotating shaft 12. During the rotation of the rotating support seat 3, its arc-shaped bottom surface always closely fits the arc-shaped surface of the installation groove 2. This design not only effectively reduces the frictional resistance during rotation, but also greatly ensures the stability of rotation, ensuring that the flow guide nozzle 1 will not shake or jam during rotation, providing a solid guarantee for the stable realization of liquid pouring and backflow functions.

[0036] In addition, the top opening of the storage groove 8 is provided with a pressing cover 10, which is rotatably connected with the storage groove 8. The storage groove 8 is provided with second shaft holes 13 on both sides of the accommodation opening 9, and the pressing cover 10 is provided with a matching second rotating shaft 14 on the side away from the accommodation opening 9. The lower end of the pressing cover 10 is provided with a pair of rib plates 15, and the rib plates 15 are provided with guide grooves 16 extending upward and downward. The flow guide nozzle 1 is provided with a sliding rod 17 which can move in the guide grooves 16. The first rotating shaft supports the flexible rotation of the flow guide nozzle 1; the second rotating shaft provides stable power for the rotation of the pressing cover 10. The guide grooves 16 and the sliding rod 17 cooperate to limit the rotation track of the flow guide nozzle 1, ensuring that it rotates along the preset path and avoiding rotation deviation. When the right side of the pressing cover 10 is pushed upward, the pressing cover 10 acts like an activated "mechanical arm" and quickly rotates to drive the flow guide nozzle 1 to turn out of the accommodation opening 9 to the right, smoothly realizing the liquid pouring function; when the right side of the pressing cover 10 is pressed downward, the pressing cover 10 drives the flow guide nozzle 1 to turn left and retract into the storage groove 8. At this time, the pressing cover 10 tightly blocks the flow guide nozzle 1 and the backflow channel 4, playing a good protective role and effectively protecting the structure of the flow guide nozzle 1 from external pollution and damage.

[0037] To prevent liquid leakage during the opening and closing of the flow nozzle 1, liquid pouring and backflow, the inner surface of the installation groove 2 is covered with a layer of flexible leakproof membrane. The leakproof membrane is made of special high molecular material, with excellent flexibility and sealing performance. During installation, the leakproof membrane closely adheres to the surface of the installation groove 2, forming a good sealing effect and effectively eliminating the risk of liquid leakage, ensuring the safety and hygiene of the product.

[0038] Based on the above-mentioned carefully designed flow nozzle 1 structure, the utility model further proposes a bottle cap containing the structure. This integrated design concept perfectly integrates the flow nozzle 1 structure with the bottle cap, providing a more convenient, efficient and practical liquid container solution for users.

[0039] Working principle

[0040] When liquid needs to be poured, the user only needs to gently pry the right side of the pressing cap 10 upwards, and the pressing cap 10 will quickly rotate at the top opening of the storage groove 8 with the second pivot axis 14 as the fulcrum. The guide groove 16 of the lower end rib plate 15 of the pressing cap 10 cooperates with the sliding rod 17 on the flow nozzle 1, driving the flow nozzle 1 to stably rotate around the first pivot axis 12 in the installation groove 2, turning out of the storage groove 8 to an inclined state, so that the outlet 5 is located outside the storage groove 8. At this time, the rotating support seat 3 is precisely rotated to the second position where the flow nozzle 1 is opened, and the inlet 6 of the flow nozzle 1 is completely coincident with the liquid passage 7 in the installation groove 2; while the outlet 20 closely adheres to the inner wall of the installation groove 2, in a closed state, completely eliminating the possibility of liquid entering the backflow channel. Under the action of gravity, the liquid in the container smoothly pours out of the container from the inlet 6 through the outlet 5 of the flow nozzle 1, realizing an efficient and precise liquid pouring process.

[0041] After the liquid pouring is completed, the user presses the right side of the pressing cap 10 downwards, and the pressing cap 10 quickly drives the flow nozzle 1 to rotate in the opposite direction, so that it is retracted into the storage groove 8. When the rotating support seat 3 rotates to the first position where the flow nozzle 1 is stored, the outlet 20 is connected with the liquid passage 7, and the liquid remaining on the outer wall of the flow nozzle 1 is guided to the back side of the flow nozzle 1 along the backflow channel 4, and then flows back to the container through the outlet 20 and the liquid passage 7, realizing efficient recovery of the remaining liquid, and fully embodying the positive significance of the utility model in resource conservation and environmental protection.

[0042] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
