Description

Nozzle and beverage machine with same Technical Field The invention relates to the field of beverage machines, in particular to a nozzle and a beverage machine with the same. Background Carbonated beverages, also known as soda water, are soft drinks that are aerated with carbon dioxide gas. In order to dissolve carbon dioxide in water to produce carbonated water, carbon dioxide having a high supply pressure is often required. The carbonated water is sprayed under high pressure in the pouring process, a large amount of bubbles and expansion are generated, and the problems of high flow rate, overlarge foam, low carbonization degree, splashing and the like are caused when the carbonated water is poured into a cup. Meanwhile, the structure of the valve mouth for pouring some carbonated water is quite complex and the cost is high. Disclosure of Invention In the summary, a series of concepts in a simplified form are introduced, which will be further described in detail in the detailed description. The summary of the invention is not intended to define the key features and essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. In accordance with a first aspect of the present invention, there is provided a carbonated water nozzle comprising: An inlet member having a fluid inlet, a fluid outlet and an interior cylindrical space between the fluid inlet and the fluid outlet; a flow restricting stabilizer located within the interior cylindrical space, the flow restricting stabilizer comprising: a flow restrictor configured as a cylinder and comprising at least three through holes extending axially through the cylinder, and A buffer part positioned below the flow limiting part, the buffer part comprising a cone part with a radial dimension of a top end smaller than a radial dimension of a bottom end of the cone part, and An outlet member connected to the inlet member; and a flow equalizer located below the flow restricting stabilizer and between the inlet member and the outlet member. In use, the nozzle will be mounted to the end of a carbonated water dispensing system for pouring carbonated water. Carbonated water in a carbonated water dispensing system flows from the fluid inlet of the nozzle, past the restrictor stabilizer. Upon passing through the through holes of the flow restrictor, the total flow rate of carbonated water will be restricted while the flow direction will be integrated, forming a carbonated water flow of the same number as the through holes. The cone portion of the buffer portion is a streamline cone, and the carbonated water flow will flow along the buffer portion due to the guidance of the buffer portion when passing through the buffer portion, become slower and even, and no serious fluid separation occurs. The fluid then flows toward the inner wall of the inlet member and continues along the inner wall of the inlet member toward the fluid outlet due to inertia, through the flow equalizer, and finally out of the nozzle. The pressure and the flow rate of the fluid passing through the nozzle are moderate, the foam is less, the carbonization degree is higher, and the splashing is not easy to occur. Optionally, the buffer portion includes a connection portion connected to the flow restricting portion, the top end of the cone portion being connected to the connection portion, and/or the buffer portion includes a column portion connected to the bottom end of the cone portion. The connecting part is positioned between the cone part and the flow limiting part, can play a role of buffering, and can prevent carbonated water flow from directly contacting with the cone part after passing through the through hole, and the column part can further limit the flow of the carbonated water flow to enable the carbonated water flow flowing through the cone part to flow along the inner wall of the inlet component to the fluid outlet. Optionally, an included angle between a generatrix of the cone portion and the axis is 5 to 85 degrees. By the angle between the cone generatrix and the axis, the flow of fluid at an acute angle to the inner surface of the inlet member can be controlled, dispersing the flow area while preventing splashing, reducing the flow rate. When the fluid contacts the inner surface of the inlet member at an acute angle, the fluid refracts downward without dispersing the flow area by splashing upward. Optionally, the projection of the through hole is located within the projection of the cone portion on the same radial plane, and/or the through hole is tangential to the buffer portion on the same radial plane. On the same radial plane, the projection of the through hole is positioned in the projection of the cone part, so that the water flow passing through the flow limiting part is guaranteed to pass through the buffer part, and flows to the fluid outlet after flowing to the inner wall of the inlet component at
