Description

Technical Field

[0001] This invention relates to the field of beverage machines, and particularly to a nozzle and a beverage machine having the same. Background Technology

[0002] Carbonated beverages, also known as soda, are soft drinks infused with carbon dioxide gas. To dissolve the carbon dioxide in water and create carbonated water, a high-pressure supply of carbon dioxide is often required. During the pouring process, this high pressure causes jetting, generating numerous bubbles and expansion, leading to problems such as high flow rate, excessive foam, low carbonation, and splashing when poured into the cup. Furthermore, some current carbonated water dispensing nozzles have very complex structures, resulting in higher costs. Summary of the Invention

[0003] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0004] In view of the shortcomings of the prior art, according to a first aspect of the present invention, a nozzle for carbonated water is provided, comprising:

[0005] An inlet component having a fluid inlet, a fluid outlet, and an internal cylindrical space located between the fluid inlet and the fluid outlet;

[0006] A current-limiting stabilizer, located within the internal cylindrical space, comprises:

[0007] A flow-limiting part, wherein the flow-limiting part is constructed as a cylinder and includes at least three through holes extending axially through the cylinder; and

[0008] A buffer section; the buffer section is located below the current-limiting section, the buffer section includes a conical section, the radial dimension of the top end of the conical section being smaller than the radial dimension of the bottom end of the conical section; and

[0009] An outlet component, which is connected to the inlet component;

[0010] A flow equalizer is located below the current limiting stabilizer and between the inlet component and the outlet component.

[0011] In use, the nozzle is installed at the end of the carbonated water distribution system to dispense carbonated water. Carbonated water in the distribution system flows into the nozzle through the fluid inlet and passes through the flow restrictor. As it passes through the through-holes of the flow restrictor, the total flow velocity of the carbonated water is limited, and the flow direction is integrated, forming a carbonated water flow equal to the number of through-holes. The conical portion of the buffer section is a streamlined cone. As the carbonated water passes through the buffer section, it is guided by the buffer section, flowing along it more slowly and evenly, without significant fluid separation. The fluid then flows to the inner wall of the inlet component and, due to inertia, continues to flow along the inner wall towards the fluid outlet, passing through the flow equalizer and finally exiting the nozzle. The fluid pressure and velocity after passing through the nozzle are moderate, with less foam, higher carbonation, and less likelihood of splashing.

[0012] Optionally, the buffer portion includes a connecting portion connected to the flow limiting portion, and the top end of the conical portion is connected to the connecting portion; and / or the buffer portion includes a cylindrical portion connected to the bottom end of the conical portion.

[0013] The connecting part is located between the conical part and the flow-limiting part, which can play a buffering role and prevent the carbonated water from directly contacting the conical part after passing through the through hole; the column part can further limit the flow rate of the carbonated water so that the carbonated water flowing through the conical part flows along the inner wall of the inlet component to the fluid outlet.

[0014] Optionally, the angle between the generatrix of the conical portion and the axis is 5 to 85 degrees.

[0015] By controlling the angle between the generatrix of the cone and the axis, the fluid can be directed at an acute angle towards the inner surface of the inlet component, thus preventing splashing and dispersing the flow area while reducing the flow velocity. When the fluid contacts the inner surface of the inlet component at an acute angle, the liquid refracts downwards and does not disperse the flow area due to upward splashing.

[0016] Optionally, on the same radial plane, the projection of the through hole is located within the projection of the conical portion; and / or on the same radial plane, the through hole is tangent to the buffer portion.

[0017] On the same radial plane, the projection of the through-hole lies within the projection of the conical portion, ensuring that the water flow through the flow-limiting section will always pass through the buffer section and flow at an acute angle towards the inner wall of the inlet component before flowing to the fluid outlet. This design prevents the fluid from flowing directly to the fluid outlet after passing through the flow-limiting section, ensuring that the buffer section functions fully and that the carbonated water flow to the fluid outlet is slow and uniform. Simultaneously, by designing the through-hole to be tangent to the buffer section, the distance the carbonated water flows through the buffer section is increased, allowing for more efficient use of the buffer's buffering effect, slowing down the carbonated water flow and making it more uniform.

[0018] Optionally, the number of through holes is 3 to 6, and they are evenly spaced along the circumferential direction; and / or the diameter of the through holes is 0.5-2 mm.

[0019] The number of through holes can be increased or decreased as needed. The equal spacing of the through holes in the circumferential direction ensures minimal interference between carbonated water flows passing through the buffer section. Furthermore, the carbonated water flows towards the inner surface of the inlet component are also less likely to interfere with each other. Simultaneously, controlling the diameter of the through holes better integrates the outflow direction of the carbonated water flowing through the flow-limiting section, concentrating it towards the buffer section and fully utilizing its buffering effect.

[0020] Optionally, the flow equalizer includes a first filter and a second filter located below the first filter, wherein

[0021] The first filter screen is 200-500 mesh, and the second filter screen is 20-40 mesh; and / or

[0022] There are two first filters and one second filter, with the two first filters stacked together.

[0023] The first filter effectively reduces the flow velocity without significantly altering the flow direction of the carbonated water, thus minimizing turbulence and splashing, and reducing carbonation loss. As a porous structure, the first filter directly and simply buffers the carbonated water flow from the upper fluid outlet, ensuring a relatively uniform flow. This avoids turbulence and splashing caused by excessive changes in flow direction, guaranteeing that dissolved carbon dioxide is minimized.

[0024] The second filter screen is located below the first filter screen and is made of stainless steel mesh with a lower mesh count. It is mainly used to increase the strength of the flow equalizer, enhance the flow equalizer's ability to resist the impact of strong water flow, and prevent the flow equalizer from undergoing severe deformation under the impact of strong water flow.

[0025] Optionally, the inlet member includes a stepped portion that protrudes radially inward from the inner surface of the inlet member for abutting against the lower surface of the flow restrictor.

[0026] The stepped portion supports the flow-limiting portion, maintaining the relative position of the flow-limiting portion in the nozzle.

[0027] Optionally, the nozzle includes an interface component that extends from the inlet into the cylindrical space, and the interface component is connected to the inlet component by means of threaded connection, snap-fit, or hook connection.

[0028] One end of the interface component extends into the inlet and is connected to the inlet component by means of threads, snap-fit, or hook; the other end of the interface structure is designed with threads or barbs for connection to the carbonated water distribution system. The carbonated water distribution system is connected to the interface component, and carbonated water flows out of the carbonated water distribution system, through the interface component, into the nozzle, and finally out of the outlet component of the nozzle, completing the dispensing of carbonated water.

[0029] Optionally, the inlet component includes a bracket located above the current limiting stabilizer and extending radially outward from the outer surface of the inlet component.

[0030] The inlet component may include a bracket, which may be connected to other structures, including but not limited to the carbonated water distribution system, to improve the stability of the connection between the carbonated water distribution system and the nozzle.

[0031] Optionally, the interface component includes a bracket positioned above the current-limiting stabilizer and extending radially outward from the outer surface of the interface component; and / or

[0032] A sealing ring is provided between the interface component and the current limiting stabilizer.

[0033] The interface component may include a bracket, which can be connected to other structures, such as a carbonated water distribution system, to improve the stability of the connection between the carbonated water distribution system and the nozzle. It can also be connected to other external structures to achieve different working effects.

[0034] To prevent carbonated water or carbon dioxide from leaking out from the connection between the inlet and outlet components, a sealing ring can be installed between the outlet and outlet components to achieve a better seal and prevent leakage of carbon dioxide or carbonated water.

[0035] According to a second aspect of the invention, a beverage machine is provided, which includes the nozzle described above. Attached Figure Description

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

Moreover, for example, the term "first component" does not imply the existence of "second component," and the term "second component" does not imply the existence of "first component."

[0068] The following detailed description is provided in conjunction with specific implementation methods.

[0069] Figure 1 A nozzle according to a first embodiment of the present invention is shown. The nozzle includes an inlet member 110, a flow restrictor 120, an outlet member 130, and a flow equalizer 131.

[0070] The inlet member 110 has a fluid inlet 110a, a fluid outlet 110b, and an internal cylindrical space 110c located between the fluid inlet 110a and the fluid outlet 110b. The outlet member 130 is connected to the inlet member 110.

[0071] The flow restrictor 120 is located within the internal cylindrical space 110c. The flow restrictor 120 includes a flow restrictor 122 and a buffer section. The flow restrictor 122 is cylindrical and includes three through holes 121 extending axially through the cylinder. The buffer section is located below the flow restrictor 122. The buffer section includes a conical section 123, the radial dimension of the apex of the conical section 123 being smaller than the radial dimension of the base of the conical section 123. The flow equalizer 131 is located below the flow restrictor 120 and between the inlet member 110 and the outlet member 130.

[0072] In use, the nozzle is installed at the end of the carbonated water distribution system to dispense carbonated water. Carbonated water in the distribution system flows into the nozzle through the fluid inlet 110a and passes through the flow restrictor 120. As it passes through the through-holes 121 of the flow restrictor 122, the total flow velocity of the carbonated water is limited, and the flow direction is integrated, forming a carbonated water flow equal in number to the through-holes 121. The conical portion 123 of the buffer section is a streamlined cone. As the carbonated water passes through the buffer section, it is guided by the buffer section, flowing along it more slowly and evenly, without significant fluid separation. The fluid then flows to the inner wall of the inlet member 110 and, due to inertia, continues to flow along the inner wall of the inlet member 110 towards the fluid outlet 110b, passing through the flow equalizer 131, and finally exiting the nozzle. The fluid pressure and velocity after passing through the nozzle are moderate, with less foam, higher carbonation, and less likelihood of splashing.

[0073] Preferably, the buffer portion includes a connecting portion 124 connected to the flow-limiting portion 122, and the top end of the conical portion 123 is connected to the connecting portion 124. Alternatively, the buffer portion includes a cylindrical portion 125 connected to the bottom end of the conical portion 123.

[0074] The connecting part 124 is located between the conical part 123 and the flow limiting part 122, which can play a buffering role and prevent the carbonated water from directly contacting the conical part 123 after passing through the through hole 121; the column part 125 can further limit the flow rate of the carbonated water so that the carbonated water flowing through the conical part 123 flows along the inner wall of the inlet member 110 to the fluid outlet 110b.

[0075] In addition, the inlet member 110 includes a stepped portion 111 that protrudes radially inward from the inner surface of the inlet member 110 and abuts against the lower surface of the flow restrictor 122.

[0076] Carbonated water first flows from the interface member 140 into the fluid inlet 110a of the inlet member 110. The interface member is connected to the inlet member 110 by means of threads, snap-fit, or hook connection, preferably, as shown below. Figure 2 As shown, the interface component 140 and the inlet component 110 are connected by threads.

[0077] The carbonated water then flows through the flow restrictor 120. The lower surface of the flow restrictor 120 abuts against the step portion 111 of the inlet member 110 and is supported by the step portion 111, thus stabilizing it within the inlet member 110. Under the action of the three through holes 121 on the flow restrictor portion 122 of the flow restrictor 120, the total flow rate of the carbonated water from the fluid inlet 110a is restricted, and the flow direction is controlled to flow along the three through holes 121 towards the conical portion 123. After contacting the conical portion 123, the liquid flows along the streamlined cone-shaped conical portion 123. During this flow process, the fluid flow velocity becomes slower and more uniform under the guidance of the conical portion 123.

[0078] The through holes 121 are evenly spaced along the circumferential direction to maximize the distance between the carbonated water flows through different through holes and minimize mutual interference when the subsequent carbonated water flows through the conical part 123. The diameter of the through holes 121 can be 0.5-2mm. The smaller diameter can limit the total flow rate of carbonated water and ensure that the carbonated water flowing through the flow-limiting part 122 is in a uniform direction, so that the conical part 123 can fully play its role.

[0079] On the same radial plane, the projection of the through hole 121 lies within the projection of the cone portion 123. This ensures that the water flow passing through the flow-limiting portion 122 will definitely pass through the buffer of the cone portion 123 and flow at an acute angle towards the inner wall of the inlet member 110. This prevents the fluid from flowing directly to the fluid outlet 110b after passing through the flow-limiting portion 122, ensuring that the cone portion 123 is in full contact with the carbonated water flow. Consequently, the carbonated water flow towards the fluid outlet 110b is slower and more uniform. At the same time, by designing the through hole 121 to be tangent to the cone portion 123, the length of the distance the carbonated water flow passes through the cone portion 123 is increased. This allows for more full utilization of the buffering effect of the cone portion 123, slowing down the carbonated water flow and making it more uniform.

[0080] After the carbonated water flows through the cone section 123, it is ejected along the direction of the cone section 123 under the action of inertia. The ejection angle is approximately the angle between the generatrix of the cone section 123 and the axis. By controlling the angle between the generatrix of the cone section 123 and the axis, the angle at which the fluid flows toward the inner surface of the inlet member 110 can be controlled.

[0081] Preferably, to prevent splashing and dispersion of the flow area, which would lead to a decrease in flow velocity, when the carbonated water comes into contact with the inner surface of the inlet member 110, the angle between the cone portion 123 and the generatrix is ​​set to 5 to 85 degrees. When the fluid contacts the inner surface of the inlet member 110 at an acute angle, the liquid refracts downwards and will not disperse the flow area due to upward splashing.

[0082] After the carbonated water comes into contact with the inner surface of the inlet component 110, it forms an annular flow region along the inner surface of the inlet component 110 due to pressure and its own inertia. The cross-sectional area of ​​the annular flow region is smaller than the cross-sectional area of ​​the outlet component. The carbon dioxide that escapes during the flow will concentrate in the small circles inside the annular region.

[0083] The carbonated water then flows to the flow equalizer 131 of the outlet component 130. For example... Figure 11 As can be seen, the flow equalizer 131 includes an annular component 131a, a first filter screen 131b located inside the annular component 131a, and a second filter screen (not shown) located below the first filter screen 131b. The first filter screen 131b can be 200-500 mesh, and the second filter screen can be 20-40 mesh. There are two first filter screens 131b and one second filter screen, with the two first filter screens 131b stacked. The first filter screen 131b can effectively reduce the flow velocity without significantly altering the flow direction of the carbonated water, reducing turbulence and splashing, and minimizing carbonation loss.

[0084] The first filter screen, with its porous structure, can directly and simply buffer the carbonated water flow from the upper fluid outlet 110b and ensure a relatively uniform water flow. This avoids problems such as turbulence and splashing caused by excessive changes in water flow direction, ensuring that dissolved carbon dioxide is not lost as much as possible. The second filter screen, located below the first filter screen, is made of low-mesh stainless steel mesh and is mainly used to increase the strength of the flow equalizer 131, enhance its ability to withstand strong water flow impacts, and prevent severe deformation of the flow equalizer 131 under the impact of strong water flow.

[0085] As the carbonated water flows out of the flow equalizer 131 from the inner surface of the inlet component 110, the cross-sectional area of ​​the flow increases, and the flow velocity decreases significantly. Simultaneously, due to the porous structure of the flow equalizer 131, the water flow direction remains relatively uniform without significant change. Small circles of carbon dioxide located within the annular region are released from the central area of ​​the flow equalizer 131, reducing the acceleration effect on the carbonated water flow and significantly reducing foaming.

[0086] Figure 4 A nozzle according to a second embodiment of the present invention is shown. Except for the construction of the sealing ring and the flow restrictor stabilizer, the nozzle according to the second embodiment has substantially the same construction as the nozzle according to the first embodiment, and structures with the same functions are given the same reference numerals. Therefore, for the sake of brevity, only the distinguishing technical features are described in detail here.

[0087] Optionally, such as Figure 4As shown, in the second embodiment, a sealing ring 250 can also be installed between the flow limiter 220 and the interface member 240. The sealing ring 250 can prevent carbonated water or carbon dioxide from leaking out from the connection between the inlet member 210 and the interface member 240, providing a better sealing effect.

[0088] Furthermore, the current limiting stabilizer 220 in the second embodiment has three through holes. In practice, the number of through holes in the current limiting stabilizer can be selected as needed; for example, it can be [number of holes]. Figure 3 ,as well as Figures 8 to 10 The diagram shows 3 through holes, 4 through holes, 5 through holes, and 6 through holes, etc.

[0089] Figure 5 A nozzle according to a third embodiment of the present invention is shown. Except for the outlet component, the nozzle according to the third embodiment has substantially the same construction as the nozzle according to the second embodiment, and structures with the same functions are given the same reference numerals. Therefore, for the sake of brevity, only the distinguishing technical features are described in detail here.

[0090] The nozzle of the third embodiment includes an inlet component 310, a flow limiter 120, an outlet component 330, a flow equalizer 331, and an interface component 340.

[0091] Optionally, such as Figure 5 As shown, when there are requirements for the nozzle outlet diameter, the size of the bottom of the inlet component 310 can be reduced, and the diameter of the matching outlet component 330 can be reduced accordingly, so that the outer diameters of the inlet component 310 and the outlet component 330 are the same. This design can optimize the spatial structure of the nozzle, reduce the size of the nozzle without affecting its use, and facilitate practical application.

[0092] Figure 6 A nozzle according to a fourth embodiment of the present invention is shown. Except for the inlet member and the flow restrictor stabilizer, the nozzle according to the fourth embodiment has substantially the same construction as the nozzle according to the third embodiment, and structures with the same functions are given the same reference numerals. Therefore, for the sake of brevity, only the distinguishing technical features are described in detail here.

[0093] The nozzle of the fourth embodiment includes an inlet component 410, a flow limiter 220, an outlet component 430, a flow equalizer 431, a bracket 412, and an interface component 440.

[0094] Optionally, such as Figure 6As shown, in the fourth embodiment, the inlet member 410 includes a bracket 412. The bracket 412 is located above the flow restrictor 420 and extends radially outward from the outer surface of the inlet member 410. The bracket 412 can be connected to other structures, including but not limited to a carbonated water distribution system, to improve the stability of the connection between the carbonated water distribution system and the nozzle.

[0095] Figure 7 A nozzle according to a fifth embodiment of the present invention is shown. Except for the inlet member and the interface member, the nozzle according to the fifth embodiment has substantially the same construction as the nozzle according to the third embodiment, and structures with the same functions are given the same reference numerals. Therefore, for the sake of brevity, only the distinguishing technical features are described in detail here.

[0096] The nozzle of the fifth embodiment includes an inlet component 510, a flow limiter 120, an outlet component 530, a flow equalizer 531, a bracket 512, and an interface component 540.

[0097] Optionally, such as Figure 7 As shown, in the fifth embodiment, the interface member 540 includes a bracket 512 located above the flow limiter 520 and extending radially outward from the outer surface of the interface member 540. The bracket 512 can be connected to other structures, such as a carbonated water distribution system, to improve the stability of the connection between the carbonated water distribution system and the nozzle. It can also be connected to other external structures to achieve different working effects.

[0098] In addition, such as Figure 12 and Figure 13 As can be seen, interface member 640 has a threaded portion 641. Another interface member 740 has a threaded portion 741 and a sealing portion 742.

[0099] During use, the interface component 640 is connected to the corresponding inlet component through the threaded part 641 below it, and the other end of the interface component 640 is connected to the corresponding carbonated water distribution system.

[0100] The interface component 740 is connected to the corresponding inlet component via its threaded portion 741, and the other end of the interface component 740 is connected to the corresponding carbonated water distribution system. When connected to the carbonated water distribution system, the sealing portion 742 on the interface component 740 can prevent carbonated water and carbon dioxide from leaking from the connection between the interface component 740 and the carbonated water distribution system, thereby improving the sealing performance of the connection between the carbonated water distribution system and the nozzle.
