The invention relates to the technical field of liquid distribution, in particular to a liquid distribution device with a remaining material warning function and an extraction tube used for the liquid distribution device.

Background technique

In liquid dispensing devices such as beverage machines, pressure pumps such as air pumps or hydraulic pumps are usually used to extract liquids such as beverages in the barrels through pipes and discharge them from the valve nozzles. For example, due to the application requirements of store brands, it is often necessary to remind the operator of the remaining material in the barrel to prepare for replenishment in advance.

The liquid distribution devices currently on the market generally use electronic monitoring to realize replenishment reminders. For example, install a flow switch on the liquid output pipe to feedback the liquid volume flowing out, and calculate the remaining volume by subtracting the outflow volume from the total volume in the barrel, and then complete the monitoring of the remaining volume. For another example, place probes, floats and other liquid level sensors inside the barrel, or place infrared, sound wave and other liquid level sensors on the outer wall of the barrel. When the remaining material reaches the warning level, a red light or alarm will be used to remind.

At the same time, the description about the orientation that may be used in the following description, such as "upper", "lower", "inner", "outer", "left", "right", "radial", "axial", etc., Unless there is a clear description, it is only for convenience of description, and will not form any limitation on the technical solution of the invention.

Fig. 1 is a schematic diagram of a device for distributing liquid from a container 80 according to the present invention. In the present invention, the “container” is used to generally describe a container suitable for storing liquid, including sealed and unsealed containers, and can be in various shapes such as cans, barrels, boxes, bottles, etc. The device according to the present invention is also called a "liquid dispensing device" and is used to remove a quantitative amount of liquid from a container.

As shown in the figure, the liquid distribution device includes a pressure pump 10, which is suitable for providing power for the flow of liquid. For this purpose, it can be selected according to the requirements of the application, such as a pressure pump powered by an air compressor. The inlet of the pressure pump 10 is connected to the extraction tube 20, and the extraction tube 20 extends into the container 80, so that the liquid in the container is drawn out through the extraction tube under the action of the pressure pump. The outlet of the pressure pump 10 is connected to a delivery pipe 90 to output the liquid extracted from the container. For example, a valve may be provided on the pipeline of the conveying pipe 90. In addition to controlling the opening and closing of the conveying flow path, the valve may also be set to be linked with the pressure pump, so that the pressure pump is started while the flow path is opened, and the flow path is closed. Stop the pressure pump at the same time.

The extraction tube 20 is set as a continuous tube in FIG. 1, the two ends of the tube are respectively an input end 22 and an output end 21, wherein the input end 22 is adapted to extend into the inner cavity of the container 80, and the output end 21 is adapted to It is connected to the inlet of the pressure pump 10 to extract liquid from the container under the drive of the pressure pump. In addition to the terminal port of the input terminal 22 as the first input port 23, another opening is provided at a certain distance from the end as the second input port 24. After the extraction tube is located in the container 80, the position h1 of the first input port 23 in the container is almost close to the bottom of the tank, thereby allowing the extraction of almost all available liquid in the container, while the second input port 24 is located at the bottom of the tank. The position h2 in the container has a higher liquid level than the first input port 23. The position of the second input port 24 is set to correspond to the state where there is not much liquid remaining in the container and it is necessary to prepare for refilling at any time.

In the normal liquid distribution process, when the liquid level in the container 80 is higher than the position h2 of the second input port, the liquid can enter the extraction tube 20 from the first input port 23 and the second input port 24 at the same time. As the liquid in the container becomes less and less, until the liquid level is lower than the position h2 of the second input port, the liquid only enters the extraction pipe from the first input port 23, and a large amount of air is sucked in from the second input port 24. This makes the liquid flowing out of the output pipe 90 significantly reduce, and the sound is made due to the intake of air from the second input port, so that both visual and acoustic alarms of insufficient remaining material are issued simultaneously to remind the operator to prepare for refilling.

Fig. 2 is a schematic diagram of the principle of another embodiment of the liquid distribution device according to the present invention. The main difference from the liquid distribution device in Fig. 1 lies in the modification of the extraction tube. Specifically, the extraction pipe is composed of a main pipe 30 and a branch pipe 40, one end of the main pipe 30 is connected to the inlet of the pressure pump 10, the other end is formed as the first input port 23, and one end of the branch pipe 40 is connected The main pipe 30 and the other end are formed as the second input port 24. The main pipe 30 and the branch pipe 40 may be provided as an integral piece, or they may be formed by connecting the branch pipe to the main pipe after being formed separately. Compared with the second input port directly opened on the side wall of the extraction tube in FIG. 1, the extraction tube in FIG. Better tube strength.

Fig. 3 is a schematic diagram of another embodiment of the liquid distribution device according to the present invention, with a further modification of the extraction tube. Specifically, the extraction pipe includes a main pipe 30, a first branch pipe 40, and a second branch pipe 50. One end of the main pipe 30 is connected to the inlet of the pressure pump 10, and the other end is connected to a pipe joint 60. The first branch pipe 40 and the second branch pipe 50 are arranged side by side and connected to the main pipe through a common pipe joint 60. One end of the first branch pipe 40 is connected to the pipe joint 60, the other end is formed as the first input port 23, one end of the second branch pipe 50 is connected to the pipe joint 60, and the other end is connected to the pipe joint 60. The second input port 24 is formed.

Fig. 4 is a schematic diagram of another embodiment of the liquid distribution device according to the present invention, with a further modification of the extraction tube. Specifically, the extraction pipe includes a main pipe 30, a first branch pipe 40, and a second branch pipe 50. One end of the main pipe 30 is connected to the inlet of the pressure pump 10, and the other end is connected to a pipe joint 60. The two branch pipes 50 are sleeved on the first branch pipe 40 and are commonly connected to the pipe joint 60 to communicate with the main pipe 30. The free end of the first branch pipe 40 forms a first input port 23, the end of the second branch pipe 50 forms a second input port 24, and a gap is left between the first branch pipe 40 and the second branch pipe 50 to form a passage for liquid or gas to flow through aisle.

Fig. 5 is a schematic diagram of another embodiment of the liquid distribution device according to the present invention, which further modifies the extraction tube. Specifically, the input end of the extraction tube of the liquid distributor includes three input ports: a first input port at the end, a second input port with a higher liquid level than the first input port, and a second input port with a higher liquid level than the first input port. The third input port for higher liquid level.

After the extraction tube is located in the container, the position h1 of the first input port in the container is almost close to the bottom of the tank, thereby allowing almost all liquid in the container to be extracted. As the liquid in the container becomes less and less, when the liquid level is lower than the position h2 of the second input port, the liquid only enters the extraction tube from the first input port and the third input port, and at the same time enters a large amount from the second input port. Air. This makes the flow from the output pipe significantly reduced, and it will make a sound due to the intake of air from the second input port, so that both visual and acoustic alarms of insufficient remaining material will be issued to remind the operator to prepare for refilling.

When the liquid in the container is further reduced to a position lower than the third input port, the liquid only enters the extraction pipe from the first input port, and a large amount of air enters from the second input port and the third input port at the same time. This further reduces the flow rate from the output pipe, and makes a louder sound due to the intake of air from the second input port and the third input port, thereby reminding that both visual and audible alarms of serious shortage of residual material will be issued. , To remind the operator to replenish the material as soon as possible.

The extraction tube shown in Fig. 5 is arranged with multiple input ports with different liquid levels, allowing multi-level warnings on the degree of remaining material in the container, and it is convenient for the operator to grasp the remaining amount of liquid in the container. It is beneficial that in addition to the configuration with three input ports shown in the figure, more input ports can be provided as required. In addition, each input port can be set to have different calibers to achieve different flow rates and audible alarms at different liquid levels.

Fig. 6 is a schematic diagram of another embodiment of the liquid distribution device according to the present invention, which further modifies the extraction tube. Compared with the embodiment shown in FIG. 5, except for the first input port 23 at the end of the extraction tube, other input ports with higher liquid levels are not directly arranged on the tube body of the extraction tube, instead of the tube from the main pipe. The end of the branch that extends from the body. Specifically, the extraction pipe is composed of a main pipe 30, a first branch pipe 40, and a second branch pipe 50. One end of the main pipe 30 is connected to the inlet of the pressure pump 10, and the other end is formed as the first input port 23. One end of a branch pipe 40 is connected to the main pipe 30, the other end is formed as the second input port 24, one end of the second branch pipe 50 is connected to the main pipe 30, and the other end forms the third input port 25 .
