The flow guide device in the prior art only has a liquid guide channel, when the flow guide device is used, the flow guide device is inserted into a container, if an inlet of the container is smaller, the outer side wall of the liquid guide channel is tightly attached to the inner wall of the inlet of the container, so that no gap or too small gap exists between the outer side wall of the flow guide device and the inner wall of the inlet of the container, and in the process that liquid flows into the container through the flow guide device, because of the inflow of the liquid in the container, air in the container cannot be timely and smoothly discharged out of the container, the air pressure in the container is increased to be higher than the atmospheric pressure, the speed of the liquid flowing into the container is influenced, and when the air is exhausted upwards along the liquid guide channel, if the flow rate of the liquid is not controlled well, the liquid in the flow guide device is also subjected to great risk of bubbling and splashing.

In order to solve the above problems, the present invention provides a flow guiding device.

Referring to fig. 2, in the present embodiment, the flow guiding device 10 includes a device body 100 and a flow guiding outer tube 200. The device body 100 includes a liquid inlet pipe 110 and a flow guide inner pipe 120 disposed at a lower end of the liquid inlet pipe 110, wherein flow guide channels are formed in the liquid inlet pipe 110 and the flow guide inner pipe 120; the outer diversion pipe 200 is sleeved on the outer periphery of the inner diversion pipe 120, an exhaust passage 300 is formed between the outer diversion pipe 200 and the inner diversion pipe 120, and the exhaust passage 300 is provided with an exhaust outlet 310.

Specifically, the liquid guiding channel 130 has a liquid inlet 111 and a liquid outlet 121, and the liquid inlet 111 and the liquid outlet 121 are respectively disposed at the upper end of the liquid inlet pipe 110 and the lower end of the inner flow guiding pipe 120. When the flow guiding device 10 is used, the inner flow guiding tube 120 and the outer flow guiding tube 200 are inserted into an inlet of a container for loading liquid, the liquid to be guided is poured into the flow guiding device 10 through the liquid inlet 111, and the liquid is discharged into the container through the liquid outlet 121 after entering the liquid guiding channel 130. As the liquid is introduced into the container through the deflector 10, the air pressure in the container gradually increases as the space for containing the air becomes gradually smaller. The inner diversion pipe 120 and the outer diversion pipe 200 are inserted into the container, an exhaust passage 300 is further formed between the inner diversion pipe 120 and the outer diversion pipe 200, and the exhaust passage 300 is further provided with an exhaust outlet 310 communicated with the outside. Under the action of the pressure difference, the air in the container flows into the air exhaust channel 300 and is finally exhausted to the external atmosphere through the air exhaust outlet 310, so that the phenomenon that the air in the container is exhausted from the liquid guide channel 130, and the liquid in the liquid guide channel 130 bubbles or even splashes out is avoided. Meanwhile, as the air in the container is discharged, the pressure in the container is consistent with the external atmospheric pressure, and the air pressure in the container is no longer used as resistance for introducing the liquid from the liquid guide channel 130 into the container, so that the liquid guide process of the flow guide device 10 becomes smoother.

Referring to fig. 3, in particular, in an embodiment, the outer diversion pipe 200 is connected to the inner diversion pipe 120, and the exhaust outlet 310 is disposed on the outer diversion pipe 200. The gas in the container enters the exhaust channel 300 from the lower part of the exhaust channel 300 and is then exhausted to the atmosphere through the exhaust outlet 310 on the outer diversion pipe 200, and at this time, it needs to be ensured that after the outer diversion pipe 200 is inserted into the container, the exhaust outlet 310 is located above the inlet of the container, so that the gas in the exhaust channel 300 can be smoothly exhausted to the atmosphere. Therefore, the diversion outer tube 200 may be set to gradually decrease in outer diameter from top to bottom, and the outer diameter of the diversion outer tube 200 at the lower end of the exhaust outlet 310 is ensured to be greater than the inner diameter of the inlet of the container into which the diversion device 10 is inserted, so that after the diversion outer tube 200 is inserted into the inlet of the container, the diversion outer tube 200 is clamped at the inlet of the container, and simultaneously, the exhaust outlet 310 is located above the inlet of the container.

Different from the previous embodiment, or on the basis of the previous embodiment, a limiting portion is convexly arranged on the side wall of the outer diversion pipe 200, and the limiting portion is located below the exhaust outlet 310. When the maximum outer diameter of the limiting portion is set to be larger than the inner diameter of the inlet of the container into which the diversion device 10 is inserted, the limiting portion abuts against the inlet of the container, and the portion, located above the limiting portion, of the diversion outer tube 200 is limited above the inlet of the container. The limiting portion is located below the exhaust outlet 310, that is, the exhaust outlet 310 is located in the outer diversion pipe 200 above the limiting portion, so that the exhaust outlet 310 is located above the inlet of the container, thereby ensuring smooth exhaust of the gas in the container.

When the outer diversion pipe 200 is connected to the inner diversion pipe 120, the exhaust outlet 310 is arranged outside the outer diversion pipe 200, and can also be arranged between the outer diversion pipe 200 and the inner diversion pipe 120, that is, the outer diversion pipe 200 is connected to the inner diversion pipe 120 in an incomplete sealing connection, and the gap between the outer diversion pipe 200 and the inner diversion pipe 120, which forms the exhaust passage 300, is used as the exhaust outlet. Similarly, to ensure that the gas in the container can be smoothly discharged, after the guiding device 10 is inserted into the container, the exhaust outlet 310 should be located above the inlet of the container or at the same level as the inlet of the container.

In another embodiment, the outer diversion pipe 200 is not connected to the inner diversion pipe 120, but is connected to the liquid inlet pipe 110. At this time, the upper end surface of the outer diversion pipe 200 is higher than the upper end surface of the inner diversion pipe 120, the upper ends of the outer diversion pipe 200 and the inner diversion pipe 120 are hermetically connected through the liquid inlet pipe 110, and the exhaust outlet 310 is arranged on the outer diversion pipe 200, and similarly, in order to ensure that the gas in the container can be smoothly discharged, after the diversion device 10 is inserted into the container, the exhaust outlet 310 should be located above the inlet of the container.

It can be concluded that the exhaust channel 300 and the liquid guiding channel 130 do not interfere with each other, and the exhaust outlet 310 is located outside the device main body 100 and will not be affected by the liquid inlet 111 and the liquid outlet 121, so that when the diversion device 10 is used, there is no problem that liquid is guided into the container through the exhaust outlet 310, and there is no problem that the exhaust outlet 310 is blocked by an excessively high liquid level in the container.

The diversion device 10 is generally used for introducing liquid into a container with a smaller inlet inner diameter, in order to facilitate the pouring of the liquid and avoid the phenomenon of liquid leakage in the pouring process, the inner diameter of the liquid inlet 111 is generally set to be several times of the inlet inner diameter of the container, namely, the inner diameter of the liquid inlet pipe 110 is larger, and the diversion inner pipe 120 needs to be inserted into the inlet of the container with a smaller size. The liquid inlet pipe 110 and the inner flow guiding pipe 120 are connected to form the liquid guiding channel 130, and if the liquid inlet pipe 110 and the inner flow guiding pipe 120 are connected at a right angle, after the liquid is poured into the liquid inlet pipe 110, the resistance of the liquid flowing into the inner flow guiding pipe 120 is increased, which results in a slow flow guiding process of the flow guiding device 10.

Referring to fig. 3, in one embodiment, the inner force of the end of the liquid inlet pipe 110 close to the inner diversion pipe 120 is gradually decreased from top to bottom, that is, the inner wall of the end of the liquid inlet pipe 110 close to the inner diversion pipe 120 is changed into an inclined surface. After the liquid is poured into the liquid inlet pipe 110, the inner wall of the inclined plane guides the liquid, so that the liquid in the liquid inlet pipe 110 can flow into the inner guiding pipe 120 more quickly. Similarly, the inner diameter of the inner diversion pipe 120 is gradually reduced from top to bottom, that is, the inner wall of the inner diversion pipe 120 is changed into an inclined surface, and when liquid flows into the inner diversion pipe 120, the inclined surface acts as a guide for the liquid, so that the liquid in the inner diversion pipe 120 can flow into the container more quickly.

As can be seen from the above, the inner diameter of the liquid inlet pipe 110 is generally much larger than the inner diameter of the inner diversion pipe 120, and when the diversion device 10 is inserted into a container for diversion, if too much liquid is diverted, which results in too much weight of the liquid in the liquid inlet pipe 110, the diversion device 10 is prone to topple over. Or in the process of guiding the flow by the flow guiding device 10, the impact generated by pouring the liquid drives the flow guiding device 10 to vibrate, so that the liquid in the flow guiding device 10 is leaked.

Referring to fig. 1 and 3, to solve the above problem, in an embodiment, the flow guiding device 10 further includes a fixing outer tube 400, the fixing outer tube 400 is sleeved on the outer circumference of the flow guiding outer tube 200, and a fixing groove 410 is formed between the fixing outer tube 400 and the flow guiding outer tube 200. The size of the fixed outer tube 400 may be adjusted according to the size of the mouth of the container into which the outer guide tube 10 is inserted, so that the mouth of the container is just inserted into the fixing groove 410 when the outer guide tube 200 is inserted into the container. After the bottle mouth of the container is inserted into the fixing groove 410, the phenomenon that the flow guide device 10 is toppled over can be prevented, meanwhile, the vibration and the shake of the flow guide device 10 can be weakened, and the liquid in the liquid inlet pipe 110 is prevented from spilling.

Since the outer fixing tube 400 is sleeved on the outer guide tube 200, the exhaust of the exhaust outlet 310, which is originally disposed on the outer guide tube 200 or between the outer guide tube 200 and the inner guide tube 120, is blocked. Therefore, after the fixed outer tube 400 is sleeved on the outer periphery of the diversion outer tube 200, the fixed outer tube 400 is required to be provided with the second exhaust outlet 420, and the second exhaust outlet 420 is communicated with the exhaust outlet 310, so as to ensure smooth exhaust of the gas in the container.

Because the inner diversion pipe 120 and the outer diversion pipe 200 are both in the shape of a circular pipe, that is, the exhaust passage 300 is the annular exhaust passage 300, when the second exhaust outlet 420 is communicated with the exhaust outlet 310, it is preferable that the second exhaust outlet 420 is arranged on the outer fixed pipe 400 at intervals in the circumferential direction, so that the gas in the container can be discharged from different directions at the same time, and the duration of increasing the gas pressure in the container can be shortened.

In the above embodiment, the shapes of the exhaust outlet 310 and the second exhaust outlet 420 are not limited, and may be circular, oval, square, rectangular, or other polygonal shapes.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
