[0002] In daily life and industrial production, deflectors are widely used for sealing and dispensing containers of beverages, wines, and cooking oils. Traditional deflectors mostly adopt a direct plug-in design, which, while simple in structure, presents many inconveniences when frequently opened and closed. For example, repeated plugging and unplugging can easily cause wear or deformation at the deflector's connection point, affecting its sealing performance; at the same time, the operation process may cause spillage or contamination of the contents, especially in scenarios requiring one-handed operation, resulting in a poor user experience.

[0003] To address the aforementioned issues, several improved flow guide designs have emerged on the market, such as rotary, push-button, or flow guides with pouring spouts. While these products enable rapid opening and closing, their sealing reliability is insufficient, and leakage is prone to occur after prolonged use. Furthermore, these solutions often have complex structures, increasing manufacturing costs, or rely on specific bottle opening designs, resulting in poor versatility.

[0004] Therefore, there is an urgent need for a flow guide that is simple in structure, easy to operate, and has excellent sealing performance. Utility Model Content

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0032] Example 1:

[0033] Please refer to Figure 1-5 This embodiment provides a flow guide with a control valve, including a connecting part 10 and a liquid outlet part 20 that are connected to each other, and a valve body assembly 30 installed between the connecting part 10 and the liquid outlet part 20.

[0034] The connecting part 10 is columnar and can be inserted into the mouth of a suitable container to fit against the inner wall of the mouth for a seal. The connecting part 10 has a first channel 11 inside and a sealing structure 12 on the outside. The sealing structure 12 is used to connect with the mouth of the bottle. The sealing structure 12 can be a cone or multi-layer sealing ring made of elastic material (such as silicone or rubber) to ensure tight contact with the mouth of the bottle and provide better liquid tightness.

[0035] The liquid outlet section 20 is the part of the flow guide located outside the bottle opening during use, mainly used to provide an operating area. The liquid outlet section 20 has a second channel 21 and a mounting cavity inside; the mounting cavity is located between the first channel 11 and the second channel 21, and the mounting cavity provides a mounting base for the valve body assembly 30.

[0036] The valve body assembly 30 includes a valve seat 31, a valve core 32, and a valve handle 33. The valve seat 31 includes an upper valve seat and a lower valve seat. The upper valve seat is connected to the liquid outlet 20, and the lower valve seat is connected to the connecting part 10, thereby fixing the valve seat 31 in the mounting cavity. A spherical groove is provided between the upper and lower valve seats. The valve core 32 is spherical in shape, thereby movably connecting the valve core 32 to the valve seat 31. The valve core 32 can rotate within the valve seat 31. The valve core 32 has a rotating shaft, and both ends of the rotating shaft are provided with connecting ends. The two connecting ends protrude from opposite sides of the mounting cavity. A sealing ring is provided on the contact surface between the connecting ends and the liquid outlet 20 to ensure its liquid tightness.

[0037] In this embodiment, the valve handle 33 is U-shaped, with its two free ends connected to the two ends of a rotating shaft, and a gripping part for easy operation provided in the middle. Power is provided by the valve handle 33 to drive the valve core 32 to switch between a first state and a second state, connecting or blocking the first channel 11 and the second channel 21.

[0038] Specifically, the valve core 32 has a connecting channel 321 inside. When the valve core 32 is in the first state, the two ends of the connecting channel 321 are respectively connected to the first channel 11 and the second channel 21, thereby connecting the first channel 11 and the second channel 21. When the valve core 32 is in the second state, the two ends of the connecting channel 321 are respectively offset from the first channel 11 and the second channel 21, thereby blocking the first channel 11 and the second channel 21.

[0039] Based on the above structure, during use, the flow guide is connected to the container by inserting the connecting part 10 into the mouth of the suitable container. A valve body assembly 30 is provided between the connecting part 10 and the liquid outlet 20. By moving the valve handle 33 up and down, the valve core 32 is switched between a first state and a second state. When the valve core 32 is moved to the first state, the two ends of the connecting channel 321 inside it are respectively connected to the first channel 11 and the second channel 21, thus establishing a liquid outlet passage of the first channel 11-connecting channel 321-second channel 21, through which the contents of the bottle can be poured out. When the valve core 32 is moved to the second state, the two ends of the connecting channel 321 are misaligned with the first channel 11 and the second channel 21, blocking the liquid outlet passage. Of course, the overlapping area of ​​the end face of the connecting channel 321 with the end faces of the first channel 11 and the second channel 21 can also be controlled by the valve handle 33 to control the opening of the liquid outlet passage and achieve controllable flow. This embodiment achieves the opening and closing of the bottle mouth and flow control functions by setting the valve body assembly 30. It eliminates the need for repeated insertion and removal, reduces physical friction between the bottle stopper and the bottle mouth, and extends the service life. The structure is simple and easy to operate. While ensuring the sealing performance, it significantly improves the efficiency of use. It is especially suitable for fast-paced life scenarios and professional application fields, and has high market promotion value.

[0040] Furthermore, a guide tube 22 is provided inside the liquid outlet 20, and the guide tube 22 has a guide channel 221 inside, which communicates with the second channel 21. The guide tube 22 can guide the liquid in the bottle to flow out in a specific direction to avoid spillage. In this embodiment, the guide tube 22 is preferably made of 304 or 316 stainless steel and is fixed inside the liquid outlet 20 by a connector; stainless steel has high structural strength, a smooth and non-porous surface, and is not easy for bacteria to grow. It can be processed into an ultra-thin guide tube 22, has strong anti-aging ability, and is suitable for long-term high-frequency use.

[0041] The guide tube 22 and the liquid outlet 20 form a double-layer leak-proof structure. Specifically, a reflux gap 23 is provided between the outer wall of the guide tube 22 and the inner wall of the liquid outlet 20, and the reflux gap 23 communicates with the second channel 21. During the use of high-viscosity liquids (such as honey and shampoo), a small amount of liquid will adhere to the surface of the outlet of the guide tube 22 after pouring. This residual liquid can flow back into the bottle through the reflux gap 23, thereby reducing the accumulation of residual liquid on the bottle stopper and preventing dripping or contamination of the bottle.

[0042] In this embodiment, the liquid outlet 20 has a tilting side 24 and a lifting side 25 on opposite sides. The tilting side 24 refers to the side of the bottle cap located below the gravity direction of the liquid outlet path during the liquid pouring process. Correspondingly, the lifting side 25 is the side of the bottle cap located above the gravity direction of the liquid outlet path during the liquid pouring process.

[0043] The valve handle 33 is located on the lifting side 25 for easy to operate.

[0044] The reflux gap 23 has a reflux bottom wall 231, which gradually slopes downward from the tilting side 24 to the lifting side 25. A reflux port 232 is provided on the reflux bottom wall 231, which is used to communicate with the second channel 21. The reflux port 232 is located close to the lifting side 25, that is, the reflux port 232 is located at the lowest point of the reflux bottom wall 231, which facilitates the reflux of residual liquid. At the same time, during the tilting process, the reflux port 232 is raised along with the lifting side 25 to prevent liquid from overflowing.

[0045] Preferably, in this embodiment, the guide tube 22 is provided with an anti-surge plate 222. The anti-surge plate 222 is located at the top of the guide tube 22 to prevent the liquid from splashing and hitting the cap during the pouring process due to excessively fast liquid flow. In this embodiment, the anti-surge plate 222 can extend the guide channel 221 towards the pouring side 24 to optimize the liquid flow path. For example, the anti-surge plate 222 can be set as an arc-shaped or S-shaped guide path with a smooth transition section to avoid generating eddies inside the channel and to guide the liquid in the bottle to flow out in a specific path direction, avoiding spillage or splashing and improving the controllability of liquid discharge.

[0046] The flow guide with control valve in this embodiment also includes a movable cover 26; the movable cover 26 is movably connected to the top of the liquid outlet 20, and a protective cavity is formed between the movable cover 26 and the liquid outlet 20, which also has a hygienic protection function.

[0047] For ease of use, the movable cover 26 in this embodiment is rotatably connected to the opening at the top of the liquid outlet 20 via a hinge shaft, so that the movable cover 26 can be flipped relative to the liquid outlet 20, and the protective cavity can be opened or closed by flipping.

[0048] In some preferred embodiments, the movable cover 26 is connected to an automatic opening and closing structure, which controls the opening and closing of the protective cavity. Normally, the automatic opening and closing structure closes the movable cover 26 within the protective cavity; during use, the automatic opening and closing structure drives the movable cover 26 to flip relative to the liquid outlet 20, automatically opening the protective cavity. After use, the automatic opening and closing structure causes the movable cover 26 to automatically reset, facilitating operation and providing a better user experience.

[0049] Although certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0050] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
