Description

Technical Field

[0001] This invention belongs to the field of liquid diversion technology, specifically relating to a diversion structure that enables liquids of different densities to be stratified. Background Technology

[0002] In artificially prepared cocktails, when the liquid needs to be layered, a spoon is usually placed in the middle of the glass, allowing the liquor to drip down from the top. If poured directly, the liquor will be affected by gravity and hit the surface of the bottom liquid, disrupting the layering effect. This operation is complex and difficult, and it is hard for people with poor dexterity to complete. In addition, holding the glass for a long time can easily cause muscle soreness in the hands, and the hands are prone to shaking, making it difficult to maintain balance. This will affect the stability of the flow of liquor or other liquids, thus affecting the layering effect and the taste. Furthermore, the existing flow guiding structures for liquid stratification are only compatible with a limited range of containers. Using a single flow guiding structure makes it difficult to adapt to appliances of different specifications, shapes, or container inlet sizes, resulting in a limited range of applicability and inconvenience in use. Utility Model Content

[0004] (2) Technical solution This utility model provides a flow guiding structure for achieving stratification of liquids of different densities, including a flow guiding rod and a liquid outlet assembly. The liquid outlet assembly includes a rotating component, one end of which is provided with a connecting hole. One end of the flow guiding rod passes through the connecting hole and is slidably connected to the rotating component. The rotating component has a liquid outlet channel communicating with the connecting hole. The flow guiding rod is provided with a flow guiding groove, and the flow guiding groove is provided with a plurality of spaced positioning grooves. The rotating component is provided with a positioning pin corresponding to the positioning groove, and the positioning pin is slidably engaged with the positioning groove.

[0005] Furthermore, the rotating component has a groove, and the positioning pin is screwed to the groove. The end of the positioning pin extends out of the groove and abuts against the positioning groove.

[0006] Furthermore, the rotating component has a groove 1 that is slidably connected to the positioning pin. One end of the positioning pin extends to the outside of the groove 1 and abuts against the positioning groove, while the other end has a groove 2. An elastic element is provided in the groove 2. One end of the elastic element abuts against the groove 1, and the other end abuts against the groove 2.

[0007] Furthermore, the guide groove extends along the axial direction of the guide rod, and the connecting hole is provided with a boss corresponding to the guide groove, the boss extending into the guide groove.

[0008] Furthermore, the liquid dispensing assembly also includes a positioning component, which is sleeved on the rotating component. One end of the positioning component is provided with a fixing part, which is used to fix the positioning component so that the rotating component can rotate freely relative to the positioning component.

[0009] Furthermore, a washer is provided between the rotating component and the positioning component, the rotating component is provided with an annular step, the annular step is provided with a first annular groove, the positioning component is provided with a second annular groove at one end away from the fixed part, and the two sides of the washer abut against the first annular groove and the second annular groove respectively.

The inlet is provided with an internal thread, and the inlet connector is screwed into the internal thread of the inlet.

[0013] Furthermore, the end of the drainage rod is also provided with a handle, the diameter of which is larger than the diameter of the connecting hole, so that the bottom end of the handle slides against the rotating part to prevent the drainage rod from slipping out of the connecting hole.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figure 1-2As shown, this utility model provides a flow guiding structure for achieving liquid stratification of different densities, including a flow guiding rod 1 and a liquid outlet assembly 2 arranged perpendicularly to each other. The liquid outlet assembly 2 includes a rotating component 21 and a positioning component 22. The positioning component 22 is sleeved on the rotating component 21. One end of the rotating component 21 is provided with a connecting hole 211. The flow guiding rod 1 passes through the connecting hole 211 and is slidably connected to the rotating component 21. The rotating component 21 is provided with a liquid outlet channel 212, which communicates with the connecting hole 211. The flow guiding rod 1 has the function of guiding the liquid flow, and the flow guiding rod 1 is connected to the connecting hole 211. A gap is provided between the holes 211. When the liquid in the liquid outlet channel 212 flows out from the connecting hole 211, the liquid will flow slowly along the gap and along the guide rod 1 to reduce the flow rate. This avoids the impact when the liquid reaches the surface of another liquid when injecting liquids of different densities, which would affect the layering effect of different liquids. It ensures that the liquid with higher density is at the bottom layer and the liquid with lower density is at the top layer. The layers are very distinct, the boundaries are clear, and the transition zone is very thin. Especially when this invention is applied to the preparation of cocktails, it is not only convenient to use, but also ensures that the prepared cocktails are more beautiful and taste better.

[0027] Specifically, the guide rod 1 is provided with a guide groove 11, which faces the outlet of the liquid outlet channel 212. The guide groove 11 contains several spaced positioning grooves 12. The rotating component 21 contains positioning pins 23 corresponding to the positioning grooves 12. The positioning pins 23 are slidably engaged with the positioning grooves 12. The engagement of the positioning pins 23 with the positioning grooves 12 fixes the positions of the guide rod 1 and the rotating component 21. Since the liquid needs to flow slowly when injecting multiple liquids, a long waiting time is required during the injection process. Simultaneously, the distance of the guide rod 1 extending beyond the connection hole 211 needs to be constantly adjusted to ensure that the bottom of the guide rod 1 always remains on the surface of the poured liquid, achieving the best liquid stratification effect. Therefore, the positioning grooves 12 and the positioning pins 23 allow the guide rod 1 to move to... When the appropriate position is used for locking and fixing, the stability of the flow rate of the liquid during downward flow can be ensured. When it is necessary to adjust the height of the guide rod 1, the positioning pin 23 can be slid out of the positioning groove 12 by grasping the guide rod 1 with the hand and applying an upward force. After adjustment, the positioning pin 23 will lock into another positioning groove 12 to fix it again. Therefore, when using this utility model, the cup can be placed on the table and kept still. By moving the guide rod 1, the bottom end of the guide rod 1 can always be kept on the liquid surface of the liquid that has been poured in. Compared with the existing technology where the height of the guide rod 1 is fixed and the bottom end of the guide rod 1 is kept on the liquid surface by adjusting the height of the container or by directly grasping and fixing the guide rod 1 with the hand, this utility model can not only free both parties and relieve hand fatigue, but also make the operation simpler. At the same time, it can better control the accuracy of liquid stratification.

[0028] Furthermore, such as Figure 3 As shown, since the flow guide 1 can move up and down relative to the rotating part 21, when the liquid dispensing assembly 2 is fixed on the table by the positioning part 22 and liquids are filled with cups or containers of different heights, in order to avoid the flow guide 1 interfering with the placement of the container, the user only needs to move the flow guide 1 up and down to place containers of different shapes or heights directly under the flow guide 1. When the flow guide 1 is moved again, it can be extended to the bottom of the container. When the beverage is adjusted, the flow guide 1 can be moved upward to remove the glass. Thus, the flow guide 1 can be used with containers of various sizes, expanding the applicability of this utility model, making it more flexible and practical.

[0029] Preferably, the end of the drainage rod 1 is further provided with a handle 13, the diameter of which is larger than the diameter of the connecting hole 211, so that the bottom end of the handle 13 slides against the rotating member 21, preventing the drainage rod 1 from slipping out of the connecting hole 211. At the same time, it can also avoid the hand from directly contacting the surface of the drainage rod 1 when adjusting the position of the drainage rod 1, thereby preventing the hand from getting wet with liquid or causing the liquid to be contaminated, thus improving the convenience of use.

[0030] Furthermore, such as Figure 2 As shown, for ease of processing and cleaning, the rotating component 21 has a groove 213. The positioning pin 23 is screwed into the groove 213. The end of the positioning pin 23 extends outside the groove 213 and abuts against the positioning groove 12. The positioning pin 23 is located above the liquid outlet channel 212, which can prevent the positioning pin 23 from obstructing the flow of liquid and prevent liquid from seeping into the positioning pin 23, increasing the difficulty of cleaning and affecting the service life of the positioning pin 23. In this embodiment, the positioning pin 23 is an M3 set screw. The outer surface of the positioning pin 23 is threaded. The groove 213 is also provided with a thread that matches the positioning pin 23. The positioning pin 23 and the groove 213 are fixed by screwing.

[0031] Preferably, the end of the positioning pin 23 that engages with the positioning groove 12 is a hemispherical structure, and the positioning groove 12 is a hemispherical groove that is adapted to the positioning pin 23. The spherical surface has a certain guiding effect on the positioning pin 23 sliding out of the positioning groove 12. Therefore, when the drain rod 1 is pulled, the positioning pin 23 and the positioning groove 12 can be slightly deformed and forcibly separated.

[0032] like Figure 4 As shown, in some embodiments, the rotating member 21 has a groove 213 that is slidably connected to the positioning pin 23. One end of the positioning pin 23 extends out of the groove 213 and abuts against the positioning groove 12, and the other end has a groove 231. An elastic member 232 is provided in the groove 231. One end of the elastic member 232 abuts against the groove 213 and the other end abuts against the groove 231. In its natural state, the elastic member 232 is always in a compressed state, so that the elastic member 232 always applies an outward pressure to the positioning pin 23, so that the positioning pin 23 is engaged with the positioning groove 12. When the drain rod 1 is moved by an external force, the positioning pin 23 will retract inward until the positioning groove 12 corresponds to the positioning pin 23. Then, the positioning pin 23 will be pushed outward under the action of the elastic body, so as to realize the engagement and fixation of the positioning groove 12 and the positioning pin 23.

[0033] Furthermore, such as Figure 5As shown, the guide groove 11 extends along the axial direction of the guide rod 1, and the connecting hole 211 is provided with a boss 214 corresponding to the guide groove 11. The boss 214 extends into the guide groove 11 and has a guiding effect on the liquid. By setting the guide groove 11 and the boss 214, the liquid can flow more concentratedly along the edge of the boss 214 in the guide groove 11, reducing the area of ​​liquid flowing on the peripheral wall of the guide rod 1, thereby reducing the amount of liquid residue on the guide rod 1 and improving the accuracy of liquid modulation.

[0034] In addition, the protrusion 214 can prevent the guide rod 1 from rotating in the connecting hole 211, causing the positioning groove 12 and the positioning pin 23 to shift, thereby affecting the adjustment efficiency of the guide rod 1.

[0035] Furthermore, such as Figure 6-7 As shown, one end of the positioning member 22 is provided with a fixing part 221. The fixing part 221 extends outward along the periphery of the positioning member 22 so that the fixing part 221 is perpendicular to the axial direction of the positioning member 22. The fixing part 221 is provided with a plurality of screw holes 2211. The positioning member 22 can be screwed and fixed to the bracket or fixed object through the screw holes 2211, thereby fixing the entire flow guiding structure on the bracket, table, or fixed object. This not only makes it convenient to use, but also frees up the hands, thus avoiding the soreness caused by prolonged hand fixation. At the same time, it can prevent hand shaking from affecting the stability of the drainage and thus affecting the liquid stratification effect.

[0036] Since the positioning element 22 is fixed in position and is sleeved on the rotating element 21, which is a cylindrical structure, the rotating element 21 can rotate freely relative to the positioning element 22. The flow guide rod 1 is also fixedly engaged with the rotating element 21, so the flow guide rod 1 can also rotate 360 ​​degrees relative to the positioning element 22. When the flow guide rod 1 rotates, the flow direction of the liquid will change accordingly. Therefore, this utility model is also applicable to containers where the inlet 217 is inclined, enabling this utility model to meet the diverse functional needs of users.

[0037] Specifically, such as Figure 8-9As shown, when the drainage rod 1 rotates, to ensure that the angle of rotation between the drainage rod 1 and the rotating component 21 is fixed, a washer 24 is provided between the rotating component 21 and the positioning component 22. The rotating component 21 is provided with an annular step 215, and the annular step 215 is provided with a first annular groove 216. The end of the positioning component 22 is provided with a second annular groove 222. The two sides of the washer 24 abut against the first annular groove 216 and the second annular groove 222 respectively, thereby increasing the friction between the rotating component 21 and the positioning component 22 to provide sufficient frictional resistance so that the rotating component 21 can resist external forces (such as gravity or slight touch) and remain stationary after reaching any position, thereby fixing the position of the drainage rod 1. Whether conducting precise liquid stratification experiments in the laboratory or mixing colorful cocktails in a bar, this utility model can bring users a convenient, efficient and stable operating experience with its unique design and excellent performance.

[0038] In this embodiment, the thickness of the washer 24 is H1, the depth of the first annular groove 216 is H2, and the depth of the second annular groove 222 is H3, where H1 = H2 + H3. This balances the frictional forces on the rotating component 21 and the positioning component 22, ensuring the stability of the fixed position. Simultaneously, after assembly, the end of the positioning component 22 abuts against the annular step 215, and the washer 24 is completely contained within the rotating component 21 and the positioning component 22, making the washer 24 invisible from the outside. This makes the overall design of this invention neater and more aesthetically pleasing.

[0039] Furthermore, the rotating component 21 is provided with external threads, and a nut 25 is screwed onto the end of the rotating component 21 away from the connecting hole 211 through the external threads. The positioning component 22 is located between the annular step 215 and the nut 25. By rotating the nut 25, the nut 25 can abut against the positioning component 22 and apply a locking force to the positioning component 22, so that the positioning component 22 is kept in close contact with the annular step 215 of the rotating component 21. This increases the friction between the rotating component 21 and the positioning component 22, strengthens the stability of the fixed position of the drainage rod 1 after rotation, and prevents the drainage rod 1 from rotating during the injection process, thereby destroying the stratification effect and requiring readjustment, thus increasing the unnecessary burden in terms of time and cost.

[0040] Preferably, a plastic washer 26 is provided between the nut 25 and the positioning member 22, so that the plastic washer 26 generates a continuous rebound force after being squeezed, so as to offset the decrease in bolt preload caused by vibration of the nut 25 during long-term use, thereby preventing the nut 25 from loosening.

[0041] In this embodiment, the groove 213 extends through the annular step 215, so that during assembly, the positioning pin 23 can enter the groove 213 from the annular step 215, which facilitates the installation and maintenance of the positioning pin 23.

[0042] Furthermore, the end of the rotating component 21 away from the connecting hole 211 is provided with an inlet 217 and an inlet connector 3 communicating with the liquid outlet channel 212. The inlet connector 3 can be connected to an infusion tube or a funnel, etc., for injecting different liquids into the liquid outlet channel 212 through the inlet connector 3. The liquid inlet direction can be from top to bottom, from bottom to top, or at an angle, etc., providing high flexibility. The inlet 217 has an internal thread 2171, and the inlet connector 3 is screwed into the internal thread 2171 of the inlet 217. Therefore, when the guide rod 1 and the rotating component 21 rotate, the position of the inlet connector 3 can always remain stationary, facilitating liquid injection during use without frequently adjusting the position of the inlet connector 3 due to the rotation of the guide rod 1, thus improving the convenience and stability of use. At the same time, this screwed connection method also facilitates the disassembly and replacement of the inlet connector 3 to adapt to the input requirements of different specifications or types of liquids, further enhancing the versatility and practicality of this utility model.

[0043] In this embodiment, the inlet connector 3 is an M5 universal elbow with external threads, which allows for flexible angle adjustment in the longitudinal direction to adapt to different inlet requirements. When liquid needs to be injected from a specific direction, simply rotate the inlet connector 3 to the appropriate angle to ensure smooth liquid flow into the outlet channel 212 without adjusting the position of the entire flow guide structure, greatly improving ease of use and flexibility. Furthermore, the inlet connector 3 is made of high-quality, corrosion-resistant, and high-pressure-resistant materials to ensure that it can withstand the erosion and pressure changes of various liquids during long-term use, maintaining structural stability and sealing.

[0044] The working principle of this utility model is explained in detail below: In use, first, the present invention is pre-fixed to the fixed object by the positioning part 22. Then, by grasping the guide rod 1 with your hand and moving it upward, the positioning pin 23 and the positioning groove 12 are forcibly disengaged to adjust the height of the guide rod 1 extending below the connection hole 211. Then, the container is placed below the guide rod 1, and then downward force is applied to move the guide rod 1 downward and extend it to the bottom of the container. At this time, the positioning pin 23 and the positioning groove 12 can be engaged to fix the position of the guide rod 1. Then, the liquid is injected into the rotating part 21 through the liquid inlet connector 3, so that the liquid flows through the liquid outlet channel 212 and flows out from the connection hole 211. Under the guidance of the guide rod 1 and the guide groove 11, the liquid will slowly flow downward into the container along the guide groove 11. When one liquid is finished, move the guide rod 1 upwards so that the bottom of the guide rod 1 is at the liquid surface position, and fix the guide rod 1 again with the positioning pin 23 and the positioning groove 12. Then, inject another liquid. The newly injected liquid will slowly flow along the guide rod 1 to the liquid surface of the already injected liquid. Repeat this process until all liquids are prepared. Finally, move the guide rod 1 upwards to remove it from the container so that the container can be removed.

[0045] Similarly, when adjusting a container with an inclined opening, simply rotate the guide rod 1 to match the angle of the guide rod 1 with the container opening.

[0046] The innovation of this invention lies in the design of a mutually perpendicular and slidably connected flow guide rod and liquid outlet assembly. The liquid outlet assembly contains a positioning pin, allowing the flow guide rod to slide freely up and down and be fixed in place. This avoids manual fixing, ensuring the stability of liquid flow, optimizing the liquid stratification process, and improving stratification accuracy and effect. Furthermore, it allows the invention to be applied to various container sizes, enhancing its versatility and practicality. In addition, the flow guide rod can rotate freely to adjust the flow angle, further expanding the invention's applicability and meeting the needs of more diverse usage scenarios, significantly improving the user experience.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
