Description

Technical Field

[0001] This application relates to the field of soda water equipment technology, and more specifically, to a soda water equipment and its soda tank. Background Technology

[0002] Soda water equipment typically uses carbon dioxide cylinders to inject carbon dioxide into water to produce soda water. Currently, most soda water equipment on the market uses pressure difference to inject pure water into the storage tank. This involves setting several small holes in the water outlet structure to transform the large water column in the pipeline into several small water streams that are atomized and sprayed out. However, the atomization effect is generally poor, resulting in a limited soda water concentration, which is difficult to meet customers' high atomization requirements.

[0003] In conclusion, how to improve the liquid atomization effect is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a soda can that atomizes liquids better than related technologies.

The nozzle is located at the second end of the liquid inlet channel, and the outlet of the second end of the liquid inlet channel guides the liquid in the liquid inlet channel to flow outwards into the interior of the nozzle. The outlet of the nozzle guides the liquid to collect and spray it out in an umbrella-shaped mist into the interior of the storage tank.

[0008] The second end of the liquid inlet channel has a star-shaped blocking block, and there is an outlet between adjacent diffusion extensions of the star-shaped blocking block. The outlet of the nozzle is directly opposite the central structure of the star-shaped blocking block, and the outlet of the nozzle is a conical orifice. The large-diameter end of the outlet of the nozzle is close to the liquid inlet channel.

[0009] Preferably, the second end opening of the liquid inlet channel is a flared mouth, with the larger diameter end of the flared mouth facing the nozzle.

[0011] Preferably, it also includes an evaporator, wherein the coil of the evaporator is coiled around the outer periphery of the liquid storage tank.

[0012] Preferably, the nozzle has swirling protrusions, the central structure of the star-shaped blocking block is mounted on the swirling protrusions, and a plurality of the swirling protrusions are arranged in a symmetrical circumferential array around the outlet axis of the nozzle, and the gap between adjacent swirling protrusions is used to guide the liquid to swirl and flow into the outlet of the nozzle.

[0013] Preferably, the liquid storage tank is equipped with a water level probe, and the detection end of the water level probe is inserted into the inner cavity of the liquid storage tank.

[0014] Preferably, the liquid storage tank has a pressure relief port, and a pressure relief valve is provided at the pressure relief port.

[0015] Preferably, the liquid storage tank includes a tank body and an end cap, the end cap is a sealing fit cover at the inlet end of the tank body, the liquid inlet channel is a channel that passes through the end cap, and the nozzle is located on the inner side of the end cap;

[0016] The end cap also has an air inlet and a liquid outlet. The air inlet is used to allow carbon dioxide to flow into the interior of the liquid storage tank, and the liquid outlet is used to allow bubble water to be discharged to the outside of the liquid storage tank.

[0017] Furthermore, the tank body is a cylindrical barrel, the end cap is a circular cap, the end cap and the tank body are arranged along the same center line, the liquid inlet channel is located at the center of the end cap, and the air inlet and the liquid outlet are located on both sides of the liquid inlet channel;

[0018] It also includes a liquid outlet pipe, which is inserted into the inside of the liquid storage tank and connected to the liquid outlet.

[0019] Preferably, the end cap has a guide tube, the liquid inlet channel is the internal cavity of the guide tube, the inner end of the guide tube is located inside the liquid storage tank, and the nozzle is sleeved on the inner end of the guide tube and threadedly engaged with it.

In use, the liquid can be introduced into the interior of the liquid storage tank through the liquid inlet channel.

[0022] To improve atomization and ensure soda concentration, nozzles are installed inside the storage tank and at the outlet of the inlet channel. These nozzles receive the liquid flowing into the storage tank through the inlet channel, pressurize it, and release it into the tank as an umbrella-shaped spray. Specifically, the outlet of the inlet channel is located around its width, preventing the liquid from flowing along the outlet end of the channel. Instead, the liquid diffuses outwards. This is manifested in the fact that the direction of liquid flow after exiting the outlet of the inlet channel forms a non-zero angle with both the outlet end's extension direction and the width direction of the channel. After being received by the nozzles, the liquid is pressurized and converges towards the center before being discharged through the small orifices of the nozzles in an umbrella-shaped spray pattern.

Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The core of this application is to provide a soda can that, compared to related technologies, atomizes liquids better. Another core aspect of this application is to provide a soda water device including the aforementioned soda can.

[0040] This application provides a soda container, including a storage tank 1 and a nozzle 2. The storage tank 1 has a liquid inlet channel 1211. The inlet of the first end of the liquid inlet channel 1211 is connected to the external environment of the storage tank 1, and the outlet of the second end of the liquid inlet channel 1211 is connected to the inner cavity of the storage tank 1. The nozzle 2 is located at the second end of the liquid inlet channel 1211. The outlet of the second end of the liquid inlet channel 1211 can guide the liquid in the liquid inlet channel 1211 to flow out in all directions to the interior of the nozzle 2. The outlet of the nozzle 2 is used to guide the liquid to collect and spray it out into the interior of the storage tank 1 in an umbrella-shaped mist.

[0041] refer to Figure 1 , Figure 2 and Figure 3As explained, the liquid storage tank 1 is a hollow tank body 11 structure, which can be used as a container for mixing liquid with carbon dioxide to form bubble water. The tank wall of the liquid storage tank 1 has a liquid inlet channel 1211 along its own thickness direction. The opening of the liquid inlet channel 1211 on the outside of the liquid storage tank 1 is the inlet, and the opening on the inside of the liquid storage tank 1 is the outlet. In use, the liquid can be introduced into the interior of the liquid storage tank 1 through the liquid inlet channel 1211.

[0042] To improve atomization and ensure proper soda concentration, refer to... Figure 4 , Figure 9 and Figure 10 As explained, a nozzle 2 is installed inside the storage tank 1 at the outlet of the inlet channel 1211 to receive the liquid flowing into the storage tank 1 through the inlet channel 1211, and to pressurize the liquid before releasing it into the storage tank 1 in an umbrella-shaped spray. The specific process is as follows (refer to...). Figure 11 and Figure 12 As explained, the outlet of the liquid inlet channel 1211 is located around its width, so that the liquid in the liquid inlet channel 1211 does not flow along the extension direction of the outlet end of the liquid inlet channel 1211, but flows out in all directions. This is directly reflected in the fact that the flow direction of the liquid after it is discharged from the outlet of the liquid inlet channel 1211 has a non-zero angle with the extension direction of the outlet end of the liquid inlet channel 1211 and the width direction of the liquid inlet channel 1211. After the liquid is received by the nozzle 2, it is gathered towards the center to achieve pressurization, and finally discharged through the small orifice of the nozzle 2 in the form of an umbrella-shaped spray.

[0043] Preferably, in some embodiments, the second end of the liquid inlet channel 1211 has a star-shaped blocking block 1212, and there is an outlet between adjacent diffusion extensions of the star-shaped blocking block 1212. The outlet of the nozzle 2 is directly opposite the central structure of the star-shaped blocking block 1212, and the outlet of the nozzle 2 is a conical orifice. The large-diameter end of the outlet of the nozzle 2 is close to the liquid inlet channel 1211.

[0044] refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8The liquid inlet channel 1211 has a star-shaped blocking block 1212 at its second end with an outlet. The star-shaped blocking block 1212 includes a central structure and several diffusion extensions. The central structure of the star-shaped blocking block 1212 can be a rectangular block or a disk, etc., while the diffusion extensions can be straight rods or arc-shaped rods, etc., and there can be four or five diffusion extensions. These diffusion extensions are arranged around the central structure, and the opposing or adjacent ends of the diffusion extensions are connected to the central structure, while the opposing or distant ends are connected to the sidewalls surrounding the liquid inlet channel 1211. The outlet of the liquid inlet channel 1211 is the gap between adjacent diffusion extensions; (See reference...) Figure 9 , Figure 10 , Figure 11 and Figure 12 As can be seen, the outlet of nozzle 2 adopts a conical opening. The large-diameter end of the outlet of nozzle 2 is located inside the nozzle 2, while the small-diameter end is located outside the nozzle 2. The outlet of nozzle 2 is directly opposite the central structure of the star-shaped baffle block 1212. In other words, several diffusion extensions of the star-shaped baffle block 1212 are located around its central structure and around the outlet of nozzle 2. That is, the outlet of the liquid inlet channel 1211 is located around the outlet of nozzle 2. Therefore, the liquid can be efficiently pressurized after flowing through nozzle 2.

[0045] It should be noted that the liquid outlet channel is not limited to the types of examples mentioned above. As long as they cooperate with each other to guide the liquid to flow along the path described in the above embodiments, for example, in some embodiments, the liquid outlet channel includes a main channel and several branch channels. The outlet of the main channel is connected to the inlet of several branch channels, and the extension direction of several branch channels has a non-zero angle with the extension direction of the main channel and the width direction of the main channel.

[0046] It should also be noted that the outlet of nozzle 2 is not limited to the types mentioned above. As long as it can pressurize and guide the liquid to be discharged in an umbrella-shaped spray, the outlet of nozzle 2 can also be an inverted trumpet shape, a hemispherical shape, or a funnel shape.

[0047] Based on the above embodiment, the second end opening of the liquid inlet channel 1211 is a flared mouth, with the larger diameter end of the flared mouth facing the nozzle 2.

[0048] refer to Figure 8 and Figure 11 As explained, the second end opening of the liquid inlet channel 1211 is a flared mouth, and the lower large diameter end of the flared mouth is directly connected to the inner cavity of the nozzle 2. When the liquid is discharged from the liquid inlet channel 1211, it will first flow through the large diameter end of the flared mouth and then through the small diameter end. The star-shaped blocking block 1212 is located in the middle of the flared mouth, and under the restriction of the side wall forming the flared mouth and the blocking block, it flows in all directions in the width direction of the liquid inlet channel 1211.

[0049] Based on the above embodiment, the second end of the liquid inlet channel 1211 has a conical protrusion 1213, which is connected to the central structure of the star-shaped blocking block 1212, and the tip of the conical protrusion 1213 is inserted into the conical outlet of the nozzle 2.

[0050] refer to Figure 6 , Figure 7 , Figure 8 , Figure 11 and Figure 12 As explained, a conical protrusion 1213 is provided below the star-shaped blocking block 1212 near the nozzle 2. The large-diameter end of the conical protrusion 1213 is directly connected to the star-shaped blocking block 1212, while the tip extends toward and inserts into the conical outlet of the nozzle 2. When the liquid flows through the outlet of the nozzle 2, the flow direction is restricted by the conical protrusion 1213 and the side wall of the nozzle 2 used to form the conical outlet, so as to further improve the pressurization effect of the liquid.

[0051] Based on the above embodiments, an evaporator 3 is also included, with the coil 8 of the evaporator 3 coiled around the outer periphery of the liquid storage tank 1.

[0052] refer to Figure 3 As can be seen, in this embodiment, the coil 8 of the evaporator 3 is spirally wound around the outside of the liquid storage tank 1, thereby cooling the liquid in the liquid storage tank 1 and further increasing the concentration of the soda water.

[0053] Based on the above embodiment, the nozzle 2 has a swirling protrusion 21, the central structure of the star-shaped blocking block 1212 is mounted on the swirling protrusion 21, and a plurality of swirling protrusions 21 are arranged in a symmetrical circumferential array around the outlet axis of the nozzle 2. The gap between adjacent swirling protrusions 21 is used to guide the liquid to swirl and flow into the outlet of the nozzle 2.

[0054] refer to Figure 9 and Figure 10 As explained, a swirling protrusion 21 is provided on the inner side of the end wall of the nozzle 2 with the outlet. Several swirling protrusions 21 are evenly distributed around the outlet of the nozzle 2. In other words, several swirling protrusions 21 are evenly distributed along the same circumference with the outlet of the nozzle 2 as the axis of rotational symmetry. The gap between adjacent swirling protrusions 21 serves as a flow channel for liquid flow. The flow channel is a channel with gradually narrowing width, and the small openings of several flow channels are close to each other, while the large openings are far apart.

[0055] In conjunction with, refer to Figure 11 and Figure 12As explained, the central structure of the star-shaped baffle 1212 is positioned above the swirling boss, and the overlapping surface of the swirling boss and the star-shaped baffle 1212 is flat and tightly fitted. As a result, the liquid cannot pass through the gap between the star-shaped baffle 1212 and can only pass through the guide channel between adjacent swirling bosses, thus allowing it to swirl towards the conical outlet of the nozzle 2.

[0056] refer to Figure 1 and Figure 2 As can be seen, based on the above embodiment, the soda can is also equipped with a water level probe 4. A detection port is also provided on the wall of the storage tank 1. The water level probe 4 passes through the detection port, and the detection end of the water level probe 4 is inserted into the interior of the storage tank 1, while the electrical connection end is located outside the storage tank 1, so that the liquid level in the storage tank 1 can be detected in real time.

[0057] refer to Figure 1 and Figure 2 As can be seen, based on the above embodiment, a pressure relief port is also provided on the tank wall of the liquid storage tank 1, and a pressure relief valve 5 is provided in the pressure relief port so as to adjust the internal pressure of the liquid storage tank 1 as needed.

[0058] Based on the above embodiments, the liquid storage tank 1 includes a tank body 11 and an end cap 12. The end cap 12 is a sealed cover at the inlet end of the tank body 11. The liquid inlet channel 1211 is a channel that passes through the end cap 12. The nozzle 2 is located on the inner side of the end cap 12.

[0059] refer to Figure 1 and Figure 2 As explained, the main structure of the liquid storage tank 1 is the tank body 11, which is used to place or contain liquids and gases. The upper end of the tank body 11 is open, and the end cap 12 is used to close the top inlet of the liquid storage tank 1. The liquid inlet channel 1211 is opened on the end cap 12. In order to allow the liquid to enter the interior of the liquid storage tank 1 in the form of an umbrella spray, a nozzle 2 is provided on the inner side of the end cap 12.

[0060] Based on the above embodiment, an air inlet 122 and a liquid outlet 123 are also provided on the end cap 12. Their functions are to allow carbon dioxide to flow into the storage tank 1 and to allow sparkling water to flow out of the storage tank 1, respectively. In use, liquid is introduced into the storage tank 1 through the liquid inlet channel 1211, and carbon dioxide is introduced into the storage tank 1 through the air inlet 122. The umbrella-shaped spray liquid and carbon dioxide come into full contact and mix, which can form sparkling water. That is, the soda can can be used to prepare sparkling water.

[0061] Based on the above embodiments, refer to Figure 1 , Figure 2 and Figure 3As explained, the storage tank 1 is a cylindrical tank. The tank body 11, which makes up the storage tank 1, is a cylindrical barrel, and the end cap 12 is a cylindrical cap. After the tank body 11 and the end cap 12 are assembled to form the storage tank 1, the center line of the tank body 11 coincides with the center line of the end cap 12. To ensure the concentration of soda water, the liquid inlet channel 1211 is opened at the center of the end cap 12. Furthermore, the air inlet 122 is located on one side of the liquid inlet channel 1211, and the liquid outlet 123 is located on the other side of the liquid inlet channel 1211. The air inlet 122, the liquid inlet channel 1211, and the liquid outlet 123 are arranged in a straight line. The detection port is located on one side of the line connecting the air inlet 122 and the liquid outlet 123, and the pressure relief port is located on the other side of the line connecting the air inlet 122 and the liquid outlet 123. With this arrangement, the layout of the soda tank is reasonable.

[0062] Based on the above embodiment, the soda can is also equipped with a water outlet pipe. The inlet end of the water outlet pipe extends to the bottom of the can, and the outlet end is inserted into the liquid outlet 123. When using the soda can, a water pump can be connected to the liquid outlet 123, or a water pump can be directly connected to it, so that the sparkling water in the soda can be easily extracted.

[0063] Based on the above embodiment, a sealing ring 7 is also included, which is sandwiched between the tank body 11 and the end cap 12, so that the tank body 11 and the end cap 12 are sealed together.

[0064] Based on the above embodiment, the end cap 12 has a guide tube 121, the liquid inlet channel 1211 is the internal cavity of the guide tube 121, the inner end of the guide tube 121 is located inside the liquid storage tank 1, and the nozzle 2 is sleeved on the inner end of the guide tube 121 and threadedly engaged with it.

[0065] refer to Figure 7 and Figure 8 As explained, the top end of the guide tube 121 protrudes upward from the outer end face of the end cap 12, and the bottom end of the guide tube 121 protrudes downward from the inner end face of the end cap 12. An external thread structure is machined on the outer periphery of the bottom end of the guide tube 121, and the nozzle 2 is threadedly fitted onto its outer side. With this configuration, the nozzle 2 is easy to assemble.

[0066] It should be noted that there are no restrictions on how the flow guide tube 121 is set in the end cap 12. For example, the flow guide tube 121 can be inserted into the opening of the end cap 12, or it can be integrally formed with the end cap, as long as the flow guide requirement is met.

[0067] Of course, the arrangement of nozzle 2 is not limited to the above examples. As long as it can meet the requirements of mating with end cap 12, for example, an annular groove is opened on end cap 12, and the inner or outer circumference of the annular groove has a threaded structure. The outer or inner circumference of nozzle 2 has a threaded structure, so that nozzle 2 can be screwed into the annular groove and threadedly mated with end cap 12.

[0068] In addition to the soda can described above, this application also provides a soda water device including the soda can disclosed in the above embodiments. The structure of other parts of the soda water device can be found in the prior art and will not be described in detail here.
