[0002] With the improvement of living standards, the demand and consumption level of beverages are also increasing, making freshly made beverage shops one of the fast-growing industries. Freshly made beverage shops can be found everywhere, and you can often see long queues.
[0003] Freshly prepared drinks require that the respective flavors of the prepared liquids be dispensed into packaging cups through a dispensing device, and then distributed to consumers. In order to improve the efficiency of beverage dispensing, existing fluid dispensing devices usually pump the prepared liquids through a fluid pump. When dispensing drinks, a large amount of prepared liquid will instantly gush out due to the pumping force of the pump, causing splashing, and the prepared liquid may require the fluid pump to dispense intermittently multiple times, thereby generating pulses in the prepared liquid, causing uneven fluid pumping, which brings inconvenience to the on-site beverage production, the pumping flow cannot be measured, and it also affects the hygiene of the preparation operation environment.

[0023] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.
[0024] Figure 1 It is a top view of an embodiment of the fluid pulse damper of the utility model, in which the upper cover and the sealing film are removed for the sake of clarity. Figure 2 yes Figure 1 Top view of the fluid pulsation dampener after installation on the cover. Figure 3 is along Figure 2 Cross-sectional side view taken at AA in FIG.
[0025] like Figure 1 As shown, the fluid pulse damper 1 includes a damper body 2 and an upper cover 7, and the upper cover 7 is removed for ease of description. The upper cover 7 is combined with the damper body 2 to define a closed chamber. An inlet 5 and an outlet 6 leading to the closed chamber are provided at opposite ends of the damper body 2. The fluid can enter from the inlet 5, pass through the closed chamber, and then flow out from the outlet 6.
[0026] A damping block 3 is arranged on the bottom wall of the closed chamber. The damping block 3 can be shaped so that the fluid entering from the inlet 5 is divided into a plurality of diffused sub-flows, and the diffused sub-flows converge near the outlet 6 and then flow out from the outlet 6.
[0027] In this embodiment, the damping block 3 divides the fluid entering from the inlet 5 into two symmetrical diffused shunts, thereby dispersing the energy of the entering fluid in the two diffused shunts, and then the two shunts merge near the outlet. In other words, the damping block 3 divides the closed chamber into two diffused passages, and the fluid entering the closed chamber is divided into two symmetrical, diffused shunts with opposite directions at the confluence by the two diffused passages, thereby dispersing the energy of the entering fluid in the two shunts, and at the same time, the two diffused passages merge again near the outlet 6, so that the energies of the shunts in opposite directions flowing out of the two passages cancel each other when they merge, thereby reducing the total energy of the merged fluid, and finally obtaining a smooth fluid flowing out of the outlet 6.
[0028] And preferably, if Figure 1As shown, the longitudinal section of the damper body 2 is rectangular, which is convenient for processing. The longitudinal profile section of the damping block 3 is a heart-shaped shape with the tip facing the inlet 5, so that the damping block 3 and the side wall of the closed chamber form two passages 4 from the inlet 5 to the outlet 6. As can be seen from the figure, the two passages 4 are two diffuse passages separated from the inlet 5, and turn towards each other near the outlet 6 and merge together.
[0029] See also Figure 2 and Figure 3 It can be clearly seen that the damper body 2 and the upper cover 7 define a closed space after being combined. The damping block 3 is arranged on the bottom wall of the closed chamber. Optionally, the damping block 3 can be integrally formed with the damper body, or can be fixed together by other suitable means, such as bonding, fastener connection, etc.
[0030] Furthermore, a sealing film 6 is provided between the damper body 2 and the upper cover 7. Preferably, the sealing film 6 is a flexible film. A buffer space 8 is provided between the flexible sealing film 6 and the upper cover 7. The combination of the flexible sealing film 6 and the buffer space 8 can further release the energy of the diffused split flows after merging, so that the fluid flowing out of the outlet 6 is smoother.
[0031] Optionally, the longitudinal section of the closed chamber of the damper body is a heart-shaped shape with the tip facing the inlet, and the longitudinal profile section of the damping block is also a heart-shaped shape with the tip facing the inlet, similar to the closed chamber shape but smaller in size, so that the damping block and the closed chamber side wall form two diffusion paths with equal cross-sections from the inlet to the outlet. Such an arrangement can also buffer fluid energy and form a smooth and uniform outflow of fluid.
[0032] Figure 4 It is a top view of another embodiment of the fluid pulse damper of the utility model, in which the upper cover and the sealing film are removed for the convenience of explanation. Figure 5 yes Figure 4 Top view of the fluid pulsation dampener after installation on the cover. Figure 6 is along Figure 5 A cross-sectional side view taken through BB in FIG.
[0033] like Figure 4 As shown, the exemplary fluid pulse damper 11 includes a damper body 12 and an upper cover 17, and for ease of description, the upper cover 17 is removed. The upper cover 17 is combined with the damper body 12 to define a closed chamber. An inlet 15 and an outlet 16 leading to the closed chamber are provided at opposite ends of the damper body 12. The fluid can enter from the inlet 15, pass through the closed chamber, and then flow out from the outlet 16.
[0034] A damping block 13 is disposed on the bottom wall of the closed chamber. The damping block 13 may be shaped so that the fluid entering from the inlet 15 is divided into a plurality of diffused sub-flows, and the diffused sub-flows converge near the outlet 16 and then flow out from the outlet 16.
[0035] In this embodiment, the damping block 13 divides the fluid entering from the inlet 15 into three symmetrical diffused flows, thereby dispersing the energy of the entering fluid in the three diffused flows, and then the three flows converge near the outlet. That is to say, the damping block 13 divides the closed chamber into three diffused passages, and the fluid entering the closed chamber is divided by the three diffused passages into three symmetrical, diffused flows, including two flows on the sides having opposite directions at the confluence, thereby dispersing the energy of the entering fluid in the three flows, and at the same time, the three diffused passages converge again near the outlet 16, so that the energies of the flows in opposite directions flowing out of the two channels on the sides cancel each other out when they converge, thereby reducing the total energy of the merged fluid, and finally obtaining a smooth fluid flowing out of the outlet 16. And preferably, as Figure 4 As shown, the longitudinal section of the damper body 12 can be rectangular, which is convenient for processing. The longitudinal profile section of the damping block 13 is a heart-shaped shape with the tip facing the inlet 15, so that the damping block 13 and the side wall of the closed chamber form two diffuse passages 14 from the inlet 15 to the outlet 16. In this embodiment, as shown in the figure, the middle part of the heart-shaped damping block 13 is also formed with an intermediate passage 141 from the inlet 15 to the outlet 16. In this way, the damping block 13 forms three passages from the inlet 15 to the outlet 16 in the closed chamber. And as shown in the figure, the three passages are divided into three diffuse passages from the inlet 15 and merge together near the outlet 16.
[0036] Such an arrangement is advantageous because the incoming fluid is diverted through three diffusion passages to obtain three diffused diverted flows, while the energy of the incoming fluid is dispersed in the three diverted flows. The energy of each diverted flow is smaller than the energy of the incoming fluid, and the diverted flows on both sides have opposite directions. When the two diverted flows converge near the outlet, the energies of the diverted flows with opposite directions can offset each other, thereby reducing the energy of the final outflowing fluid and making the outflowing fluid smoother.
[0037] See also Figure 5 and Figure 6 It can be seen that the damper body 12 and the upper cover 17 define a closed space after being combined. The damping block 13 is arranged on the bottom wall of the closed chamber. Optionally, the damping block 13 can be formed integrally with the damper body, or can be fixed together by other suitable means, such as bonding, fastener connection, etc.
[0038] Furthermore, a sealing film 16 is provided between the damper body 12 and the upper cover 17. Preferably, the sealing film 16 is a flexible film. A buffer space 18 is provided between the flexible sealing film 16 and the upper cover 17. The combination of the flexible sealing film 16 and the buffer space 18 can release the energy offset after the diffusion of the diverted flows merges, thereby making the fluid flowing out of the outlet 16 smoother.
[0039] Also optionally, the longitudinal section of the closed chamber of the damper body is a heart-shaped shape with the tip facing the inlet, and the longitudinal profile section of the damping block is also a heart-shaped shape with the tip facing the inlet, similar to the shape of the closed chamber but smaller in size than the closed chamber, so that the damping block and the side wall of the closed chamber form two passages with equal cross-sections from the inlet to the outlet. Further, a middle passage from the inlet to the outlet is formed in the middle of the heart-shaped damping block. Such an arrangement can also buffer the fluid energy and form a smooth and uniform outflow of fluid.
[0040] Theoretically, without being restricted by space, the number of the symmetrically arranged diffusion passages in the fluid pulse damper of the present invention is not limited to the two or three described in the above embodiments, but may be more.
[0041] The fluid pulse damper of the utility model can be applied to various occasions, for example, it can be used in a beverage preparation device.
[0042] Specifically, the fluid pulse damper can be used in the discharge device of the beverage preparation device, for example, it can be set in the feed pipe between the discharge port and the delivery pump. Advantageously, the fluid pulse damper can be set in the feed pipe adjacent to the discharge port. The fluid pulse damper, for example, divides the liquid flowing into its inlet into two or three diffusive streams, and after merging near its outlet, it flows out of the fluid pulse damper and flows into the discharge port to be distributed into the beverage cup. Due to the provision of the fluid pulse damper of the utility model, a smoother liquid distribution is obtained, and splashing of the liquid is prevented.
[0043] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical solution.
