[0060] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0061] Reference Figures 1 to 8 The utility model provides a nozzle, including a nozzle body 10 and a flow limiting member. The nozzle body 10 has an inlet end 11 and an outlet end 12 that are connected. The flow limiting member includes a shell 20 and a diffuser 30 that is sleeved into the shell 20. The shell 20 is connected to the inlet end 11 and is sleeved into the nozzle body 10. The end of the diffuser 30 that is sleeved into the shell 20 is closed. A connecting port 302 is provided on the wall of the diffuser 30 near the closed end 31. The connecting port 302 passes through the diffuser 30 in the radial direction. An annular gap 301 is defined between the shell 20 and the diffuser 30. The annular gap 301 is connected to the outlet end 12, and the diffuser 30 is connected to the annular gap 301 through the connecting port 302. In the utility model, by forming an annular gap 301 between the diffusion tube 30 and the shell 20, the pressure of carbonated water when flowing in the annular gap 301 will slowly decrease, which helps the carbonated water to present a laminar flow state when flowing in the annular gap 301, that is, the fluid flows along the direction of the annular gap 301, reducing the generation of eddies and turbulence, thereby slowing down the flow speed of carbonated water through the nozzle and reducing the rate of gas release in carbonated water, which helps to increase the carbonation degree of carbonated water, making the beverage more bubbly and refreshing, meeting consumers' demand for carbonated beverages.

[0062] Reference Figure 1-3 , Figure 6 and Figure 8 The nozzle body 10 is constructed as a hollow tubular structure. The shell 20 is constructed as a hollow tubular structure. The shell 20 is sleeved into the nozzle body 10. The diffuser 30 is sleeved into the shell 20. The nozzle body 10, the shell 20, and the diffuser 30 are sealed and connected in sequence. The sealing connection provides stability and sealing of the nozzle as a whole. Optionally, a sealing ring 40 is provided between the nozzle body 10 and the shell 20, and / or between the shell 20 and the diffuser 30. Optionally, when the sleeve connection is made, other connection methods can be used, and the connection methods include but are not limited to threaded connection and snap-on connection.

[0063] The housing 20 has a first end and a second end disposed opposite to each other along its axial direction. The second end of the housing 20 extends from the inlet end 11 of the nozzle body 10 to the inside of the nozzle body 10. The first end of the housing 20 extends to the outside of the nozzle body 10 and is located above the inlet end 11 of the nozzle body 10.

[0064] The diffusion tube 30 is mounted to the end of the carbonated water dispensing system for dispensing carbonated water. The diffusion tube 30 is configured as a hollow tubular structure, which includes an open end 32 and a closed end 31 disposed opposite to each other along its axial direction. The open end 32 of the diffusion tube 30 is in communication with the carbonated water dispensing system. The closed end 31 of the diffusion tube 30 extends from the first end of the housing 20 to the interior of the housing 20, and the closed end 31 of the diffusion tube 30 extends to the interior of the nozzle body 10.

[0065] A connecting port 302 is provided on the wall of the diffuser 30 near the closed end 31, and the connecting port 302 is through the radial direction of the diffuser 30. The carbonated water flowing in from the open end 32 of the diffuser 30 can flow out to the annular gap 301 through the connecting port 302, which helps to form a laminar flow state, reduce the gas release rate, and increase the carbonation degree of the carbonated water. Due to the friction resistance of the inner surface of the nozzle, the flow rate of the fluid slows down. When the fluid enters the annular gap 301 through the connecting port 302, the total flow rate of the fluid will be limited and the flow direction will be integrated to form a laminar flow fluid.

[0066] Optionally, the radial dimension of the portion of the diffuser 30 where the communication port 302 is provided is relatively small, and the portion is spaced apart from the interior of the housing 20 to form a portion of the annular gap 301. Therefore, the radial width of the annular gap 301 corresponding to the communication port 302 is relatively large, thus providing a relatively large buffer space for the fluid flowing out of the communication port 302, reducing the impact and turbulence of the fluid outflow, and helping to maintain the stability and uniformity of the fluid.

[0067] Optionally, the diffuser 30 is further provided with a boss portion 33, and the boss portion 33 is spaced apart from the inner wall surface of the housing 20 to form a portion of the annular gap 301. Optionally, the radial dimension of the boss portion 33 is greater than the radial dimension of the portion of the diffuser 30 where the communication port 302 is provided. The provision of the boss portion 33 can control the flow state of carbonated water in the annular gap 301 to a certain extent, making it more inclined to a laminar flow state. Optionally, the outer wall surface of the boss portion 33 is provided in parallel with the inner wall surface of the housing 20.

[0068] Optionally, a transition cone is provided between the boss portion 33 and the body of the diffuser 30. The provision of the transition cone helps to smoothly guide the carbonated water and reduce turbulence and eddy currents that may be generated during the transition process.

[0069] In the present invention, at least part of the annular gap 301 has a radial width of 0.04 to 0.4 mm. At least, the distance between the outer wall surface of the boss portion 33 and the inner wall surface of the housing 20 is 0.04 to 0.4 mm. The axial length of the annular gap 301 is 2 to 30 mm. The appropriate size of the annular gap 301 can promote the uniform flow of carbonated water inside the nozzle, reduce possible eddies and turbulence, and optimize the flow state of carbonated water inside the nozzle.

[0070] The closed end 31 of the diffuser 30 penetrates the shell 20 and extends into the nozzle body 10. The fluid flowing out of the communication port 302 flows into the cavity formed by the shell 20 and the nozzle body 10. Since the shell 20 is sleeved on the nozzle body 10, there is a step between the inner cavity of the second end of the shell 20 and the inner cavity of the nozzle body 10. The fluid flows out of the shell 20 into the nozzle body 10.

[0071] The through end of the diffuser 30 is provided with a cone portion 34, which is spaced apart from the inner wall of the nozzle body 10, and the radial dimension of the top end of the cone portion 34 is smaller than the radial dimension of the bottom end of the cone portion 34, and the radial dimension of the bottom end of the cone portion 34 is larger than the inner diameter of the shell 20. Therefore, the fluid flowing out of the annular gap 301 between the shell 20 and the diffuser 30 will flow along the cone portion 34, becoming more slowly and evenly, and no serious fluid separation will occur. The fluid passing through the nozzle body 10 finally flows out of the nozzle.

[0072] Optionally, the angle between the generatrix of the cone portion 34 and the axis is 15 to 75 degrees. After the fluid flows through the cone portion 34, it is ejected in the direction of the cone portion 34 under the action of inertia, and the ejection angle is approximately the angle between the generatrix of the cone portion 34 and the axis. By controlling the angle between the generatrix of the cone portion 34 and the axis, the angle of the fluid when it flows toward the inner wall surface of the nozzle body 10 can be controlled.

[0073] The diffuser 30 further includes a column portion 35 connected to the bottom end of the cone portion 34, and the column portion 35 is spaced apart from the inner wall of the nozzle body 10. The column portion 35 can further restrict the flow of the fluid so that the fluid flowing through the cone portion 34 flows along the inner wall of the nozzle body 10 toward the outlet end 12.

[0074] Reference Figure 6 The nozzle also includes an inner tube 50, which is connected to the side of the flow limiting member facing the outlet end 12. A gas outlet 501 is provided at the end of the inner tube 50 close to the flow limiting member, and the inside of the nozzle body 10 is connected to the outside world through the gas outlet 501. As can be seen from the above, the fluid flows out along the conical portion and / or the cylindrical portion 35, thereby forming an annular flow area, and the carbon dioxide escaping during the flow of the fluid will be concentrated in the small circle inside the annular flow area. The inner tube 50 is arranged inside the annular flow area, and the inner tube 50 is connected to the outside world, so that the gas inside the nozzle can be better released, thereby further reducing the flow rate of the outlet end 12. In addition, by setting the inner tube 50, the direction of fluid flow can be guided to reduce splashing.

[0075] The nozzle body 10 further includes a tapered section 13. Along the axial direction of the nozzle body 10, the tapered section 13 is located between the flow restriction member and the outlet end 12, and the cross-sectional area of ​​the tapered section 13 in the direction from the flow restriction member to the outlet end 12 gradually decreases. The provision of the tapered section 13 makes the outlet flow rate of the nozzle outlet end 12 more concentrated.

[0076] Reference Figure 5 The inner wall of the nozzle body 10 is provided with a circumferentially extending groove 101. Optionally, the groove 101 is at least provided at least in one of the tapered section 13, the wall surface of the upper part of the tapered section 13, and the wall surface of the lower part of the tapered section 13. By providing the groove 101, the flow rate of the fluid is further slowed down.

[0077] Reference Figure 7 The nozzle further comprises an interface 60, which is connected to the outlet end 12 of the nozzle body 10, and the central axis of the interface 60 is not colinear with the central axis of the nozzle body 10. Optionally, the interface 60 and the nozzle body 10 are integrally formed. Optionally, the outlet end 12 of the nozzle body 10 is inclined, and / or the interface 60 is a curved tubular shape, so that the fluid can be guided to flow to the side wall of the cup to avoid splashing, and also reduce carbonization loss.

[0078] Back to Figures 1 to 3 The shell 20 is provided with a first connecting groove 201 extending circumferentially. The first connecting groove 201 is used to connect the connecting plate 70 to fix the nozzle to the external structure. Optionally, at least part of the first connecting groove 201 passes through the shell 20 in the radial direction. The diffuser 30 is provided with a second connecting groove 303, and the second connecting groove 303 corresponds to the first connecting groove 201. The connecting plate 70 can pass through the first connecting groove 201 and connect with the second connecting groove 303. In other words, the connecting plate 70 is plug-connected with the first connecting groove 201 and the second connecting groove 303. While stabilizing the overall position of the nozzle, it is ensured that the diffuser 30 does not move axially relative to the shell 20.

[0079] like Figure 4 As shown, the diffusion tube 30 is further provided with a third connection groove 304. The third connection groove 304 is used to install the sealing ring 40 to achieve a better sealing effect and prevent carbon dioxide or carbonated water from leaking from the first end of the housing 20.

[0080] Optionally, the diffuser 30, the housing 20, and the nozzle body 10 of the present invention are integrally formed. Optionally, the diffuser 30, the housing 20, and the nozzle body 10 can be made of metal or plastic material. Optionally, the material contains inorganic silver nano antibacterial components.
