Description

Technical Field

[0001] The utility model relates to the technical field of accessories for beverage preparation devices, in particular to a flow-dividing buffer valve body. Background Art

[0002] The traditional coffee machine currently on the market mainly includes an extraction part for preparing coffee and a pressurized water supply part for providing hot water to the extraction part. The pressurized water supply part mainly includes a water tank assembly, a water pump, a heater and a one-way valve. The heater heats the water in the water tank assembly, and the heater generates steam and hot water during the heating process. After the coffee machine is finished working, the steam and hot water need to be released quickly. However, during the process of depressurization, splashing steam and hot water will be generated, which may cause scalding, thus affecting the user experience.

[0003] In view of the above problems, existing coffee machines have been improved. One way is to set a one-way valve at the pressure relief outlet of the coffee machine, and the one-way valve forcibly prevents the discharge of steam and hot water; another way is to set a buffer cavity in the coffee machine to buffer the released steam and hot water. As shown in the Chinese utility model with patent number ZL201720436984.7 (authorization announcement number CN207444801U), the coffee machine is provided with an electric heating device and a water tank on the body, a funnel is provided on the side of the water tank, a nozzle fixing plate is provided above the funnel, a nozzle is provided on the nozzle fixing plate, a top plate is provided above the nozzle fixing plate, and the edges of the top plate and the nozzle fixing plate are sealed by the water tank wall and the sealing plate to form a sealed space. The steam and hot water leaked from the nozzle undergo a buffering and cooling effect in the sealed space, thereby avoiding the occurrence of scalding incidents caused by the leakage of steam and hot water.

[0004] Although the above two methods can prevent steam and hot water from scalding users, the use of a one-way valve does not completely release the pressure generated by heating and hydraulics, and hot water may flow back into the water pump, thereby damaging the water pump; if steam flows back into the water pump, the water pump will become powerless. At this time, the steam needs to be discharged, but the one-way valve cannot discharge the steam, resulting in empty pumping. Long-term empty pumping will burn the water pump; the other method of using a buffer chamber to buffer the released steam and hot water occupies a large space and has a high production cost. In addition, if used continuously, the buffering effect of the buffer chamber will decay, so further improvement is needed. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a flow dividing and buffering valve body with a simple structure and low production cost in view of the above-mentioned existing technical status.

[0006] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: the diverter buffer valve body includes a main channel for fluid circulation, and is characterized in that: at least two diverter channels for slowing down the flow speed of the fluid are provided on the main channel, and the diverter channels are symmetrically distributed on the main channel, and an inlet and an outlet are provided at both ends of the diverter channel, and the inlet and the outlet are both connected to the main channel, and a diverter component for diverting is provided at the intersection of the inlet and the main channel.

[0007] In order to make the shunt channel slow down the speed of fluid flow, preferably, the shunt channel includes an arc segment for increasing fluid resistance, one end of the arc segment is connected to the inlet through a connecting segment, the connecting segment is a straight channel, and the flow direction of the connecting segment is set at an angle to the flow direction of the main channel, and the other end of the arc segment is bent and connected to the outlet, so that the fluid flowing out of the outlet can consume the energy of the fluid in the main channel flowing forward. In order to effectively increase the fluid resistance, the arc segment gradually bends from the end of the connecting segment toward the inlet and finally connects to the main channel.

[0008] In order to enable the fluid in the main channel to flow into the branch channel more normally, preferably, the channel diameter of the main channel is smaller than the channel diameter of the branch channel.

[0009] In order to enable the flow diverter to divert flow, preferably, the flow diverter is provided with a plurality of wall portions for slowing down the flow rate of the fluid, so that when the fluid in the main channel flows to the wall portions, the energy of the forward flow can be lost.

[0010] Furthermore, the diverter is a diamond-shaped block.

[0011] In order to slow down the flow rate of the fluid flowing out of the diverter channel, preferably, the diverter is also provided at the intersection of the outlet and the main channel. The diverter can not only slow down the flow rate of the fluid flowing out of the diverter channel, but also consume the energy of the fluid flowing forward in the main channel.

[0012] In order to facilitate the assembly of the diverter buffer valve body, it is preferred that it further includes a valve seat and a valve cover, wherein the valve cover is used to cover the valve seat, and the main channel, the diverter channel and the diverter member are provided in the space between the valve cover and the valve seat.

[0013] Furthermore, the valve seat is provided with an inlet and an outlet communicated with the main channel.

[0014] Compared with the prior art, the advantages of the utility model are: by symmetrically arranging diversion channels on both sides of the main channel to slow down the flow rate of the fluid, and arranging a diversion piece at the intersection of the inlet of the diversion channel and the main channel, it is not only convenient for the fluid to be diverted at the intersection of the diversion channel and the main channel, but also can consume the energy of the fluid flowing forward, thereby buffering the pressure of the fluid in the product and avoiding the occurrence of scalding incidents caused by steam and hot water leakage; at the same time, the diversion buffer valve body has a simple structure, a small space occupancy, and reduces the production cost of the product.

[0016] Figure 2 It is a structural schematic diagram of an embodiment of the utility model (the valve cover is omitted). DETAILED DESCRIPTION

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] like Figure 1 and Figure 2 Shown is the best embodiment of the utility model.

[0019] like Figure 1 As shown, the diverter buffer valve body of this embodiment includes a valve seat 4 and a valve cover 5. The valve cover 5 is used to cover the valve seat 4. The space between the valve cover 5 and the valve seat 4 is provided with a main channel 1, a diverter channel 2 and a diverter member 3. The valve seat 4 is provided with an inlet 41 and an outlet 42 connected to the main channel 1.

[0020] like Figure 2As shown, the main channel 1 is used for fluid circulation, and ten shunt channels 2 for slowing down the flow speed of the fluid are arranged on the main channel 1. The channel diameter of the main channel 1 is smaller than the channel diameter of the shunt channels 2. The shunt channels 2 are symmetrically distributed on the main channel 1. An inlet 21 and an outlet 22 are arranged at both ends of the shunt channel 2. The inlet 21 and the outlet 22 are both connected to the main channel 1, and a shunt member 3 for shunt flow is arranged at the intersection of the inlet 21 and the main channel 1 and the intersection of the outlet 22 and the main channel 1. Among them, the shunt channel 2 is in the shape of a Tesla valve, and the shunt channel 2 includes an arc segment 23 for increasing fluid resistance. One end of the arc segment 23 is connected to the inlet 21 through a connecting segment 24. The connecting segment 24 is a straight channel, and the flow direction of the connecting segment 24 is set at an angle with the flow direction of the main channel 1. The arc segment 23 gradually bends from the end of the connecting segment 24 toward the direction of the inlet 21 and finally connects to the main channel 1 through the outlet 22, so that the fluid flowing out of the outlet 22 can consume the energy of the fluid in the main channel 1 flowing forward. In addition, the flow divider 3 is a diamond-shaped block, and is provided with four wall portions 31 for slowing down the flow rate of the fluid. When the fluid in the main channel 1 and the flow divider 2 flows to the wall portions 31, the energy of the forward flow can be lost.

[0021] The working process of this embodiment is as follows: the fluid in the main channel 1 hits the wall 31 of the diverter 3 and is divided into three branches of fluid. The first branch of fluid continues to flow forward in the main channel 1, the second branch of fluid flows into a diverter channel 2, and the third branch of fluid flows into another symmetrical diverter channel 2. The second branch of fluid and the third branch of fluid collide with the wall of the arc segment 23 in their respective diverter channels 2, thereby dissipating the energy of the second branch of fluid and the third branch of fluid flowing forward in their respective diverter channels 2; then the three branches of fluid meet at the next diverter 3, and the fluid flowing out of the outlets 22 of the two diverter channels 2 can dissipate the energy of the fluid in the main channel 1 flowing forward, thereby slowing down the flow rate of the fluid in the main channel 1.

[0022] The diverter buffer valve body of this embodiment can be used in the pressure relief water circuit inside the coffee machine housing, or at the water outlet of the coffee machine. The diverter buffer valve body can avoid the occurrence of scalding incidents caused by leakage of steam and hot water by slowing down the flow rate of steam and hot water. In addition, the diverter buffer valve body can be connected to the exhaust hole to facilitate the discharge of air and prevent damage to the water pump due to empty pumping.
