[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention.

They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0036] In the field of beverage making, the control valve needs to have the function of conduction and cut-off, that is, when liquid circulation is required, the control valve needs to have the function of conduction, and when liquid circulation is not required, the control valve needs to have the function of cut-off; although the existing one-way valve also has the function of conduction and cut-off, it has the following shortcomings: on the one hand, the conduction and cut-off functions of the valve plate in the existing one-way valve are opened by the impact force when the liquid flows, and when the pressure of the fluid is insufficient, the valve plate conduction of the one-way valve fails; in addition, the one-way valve is limited by the design principle, and the fluid can only flow from one fixed end to the other end, thus limiting the flow direction of the fluid. To this end, the researchers proposed a control valve, so that when the control valves are docked, the pressing part in each control valve can press the valve plate control component of the other control valve, so that the control valve is in a connected state in advance, and the fluid can enter from the two ends of each control valve, thereby realizing the two-way flow of the fluid; and when the two control valves are separated, each control valve returns to the cut-off state again.

[0037] like Figure 1 As shown, Figure 1The control valve in one embodiment of the present application is a schematic diagram of the structure of the control valve, wherein the control valve comprises: a housing 100 and a valve plate control assembly 200, wherein the valve plate control assembly 200, under the action of an external force, enables the second end 130 in the housing 100 and the channel 150 to be in a connected state or a blocked state.

[0038] Specifically, the shell 100 includes an inner cavity 110, a first end 120 and a second end 130 opposite to each other, and a channel 150 connected to the inner cavity 110 is arranged on the side of the shell 100, and a pressing portion 140 is arranged on the side of the second end 130 away from the inner cavity 110; the valve plate control component 200 is arranged in the inner cavity 110 and blocks the second end 130, when the pressing portion 140 of another control valve applies pressure to the valve plate control component 200, the valve plate control component 200 opens the second end 130, and the second end 130 is connected to the channel 150; when the pressure applied to the valve plate control component 200 is removed, the valve plate control component 200 blocks the second end 130, and the second end 130 and the channel 150 are cut off.

[0039] In this embodiment, the docking of two control valves is taken as an example. When the two control valves are docked, the second ends 130 of the two control valves are opposite and close to each other. At this time, their respective pressing parts 140 press against the valve plate control assembly 200 of the other control valve. Due to the pressure of the pressing part 140 of the other control valve, the valve plate control assembly 200 in each control valve opens its own second end 130 respectively. The second end 130 of each control valve is changed from a blocked state by the valve plate control assembly 200 to an open state. The second end 130 of each control valve is connected to its own channel 150, and the two control valves are connected. The flow path of the fluid is to enter from the channel 150 of one of the control valves and flow out from the second end 130 of the control valve, thereby entering the second end 130 of the other control valve and flowing out from the channel 150 of the control valve; since the control valves are pre-pressed by the pressure portion 140 against the valve plate control assembly 200, the fluid can flow from the channel 150 of the control valve to the second end 130, and can also flow from the second end 130 to the channel 150, thereby realizing two-way flow of the control valve; when the two control valves are separated, the pressure portion 140 no longer presses the valve plate control assembly 200, and at this time the valve plate control assembly 200 in each control valve returns to the state of blocking the second end 130, and at this time the second end 130 of each control valve and the channel 150 are in a cut-off state.

[0040] It should be noted that the bidirectional flow here means that a general one-way valve can only flow from one fixed end to the other end. For example, the one-way valve has an A end and a B end. In the pre-design, the fluid flows from the A end to the B end of the one-way valve. The fluid flowing in from the A end will press against the valve plate in the one-way valve. After the valve plate is opened, the fluid can flow into the B end; and when the fluid flows from the B end to the A end, the valve plate will cut off the fluid, and the fluid cannot flow into the A end. In this embodiment, when the two control valves are docked, since the valve plate control component 200 has opened the second end 130, the fluid can enter the inner cavity 110 along the second end 130 and flow out through the channel 150, or enter the inner cavity 110 from the channel 150 and then flow out through the second end 130, thus realizing the bidirectional flow of the fluid; when the two control valves are separated, each control valve returns to the cut-off state again.

[0041] The control principle of this embodiment is different from that of the one-way valve in that the one-way valve opens the valve plate after the fluid impacts the valve plate, while in this embodiment, the valve plate control component 200 is pre-pressed by the pressing portion 140 to change the second end 130 and the channel 150 from a closed state to a connected state; in addition, due to the properties of the one-way valve itself, the fluid can only flow from one fixed end to the other end after the fluid generates an impact force on the valve plate, while the control valve in this embodiment can realize two-way flow of the fluid because the control valve can be pre-conducted; when the two control valves are separated, the control valve returns to the closed state.

[0042] Further, in one embodiment, see Figure 2 and Figure 3 As shown, the first end 120 is provided with an end cap 300, and the end cap 300 closes the first end 120; the valve plate control assembly 200 includes a rebound valve plate 210, wherein the rebound valve plate 210 includes a sealing portion 211 and a compression portion 212, the sealing portion 211 is used to block the second end 130, the compression portion 212 is pressed against the end cap 300, and the side of the compression portion 212 is in close contact with the inner cavity 110, and the elastic force generated by the compression portion 212 drives the sealing portion 211 to move away from the second end 130 or to move toward the second end 130. It should be noted that the cross-sectional area of ​​the sealing portion 211 should be larger than the cross-sectional area of ​​the flow channel 150 at the second end 130 through which the fluid can pass, so that the sealing portion 211 can block the second end 130. The compression portion 212 and the sealing portion 211 can be made of rubber.

[0043] In this embodiment, the end cap 300 can close the first end 120, and the end cap 300 and the first end 120 can be connected by a snap connection or a threaded connection. The sealing performance of the control valve can be improved by providing the end cap 300. In addition, the end cap 300 can also press against the compression part 212. When the compression part 212 is subjected to a force, the compression part 212 can press against the end cap 300, so that the compression part 212 is compressed and deformed. The sealing part 211 in the rebound valve plate 210 is used to block the second end 130. The compression part 212 can drive the sealing part 211 to move when it is compressed or restored. When the side wall of the compression part 212 presses against the inner cavity 110, the fluid entering the inner cavity 110 can be limited between the rebound valve plate 210 and the second end 130, thereby reducing the residual area of ​​the fluid in the inner cavity 110.

[0044] Specifically, two control valves are used as an example again. When the two control valves are connected, the pressing part 140 of one of the control valves presses the sealing part 211. At this time, the sealing part 211 transmits the force to the compression part 212. When the compression part 212 is compressed, the sealing part 211 drives the sealing part 211 to move away from the second end 130. At this time, the second end 130 of each control valve is connected to the respective channel 150. The fluid entering the inner cavity 110 of the control valve is between the second end 130 and the rebound valve plate 210, and the fluid can flow between the second end 130 and the channel 150. When the two control valves are separated, that is, the pressing part 140 no longer presses the rebound valve plate 210, the compression part 212 recovers its deformation from the compressed state, and the compression part 212 drives the sealing part 211 to move toward the second end 130 again. The sealing part 211 blocks the second end 130 again, and each control valve is restored to the cut-off state again.

[0045] In one embodiment, see Figure 2 As shown, a boss structure 310 is provided on one side of the end cover 300 close to the second end 130, wherein the boss structure 310 may be annular, but the boss structure 310 is not limited thereto, and may also be, for example, a polygonal structure, wherein a limiting groove 311 is provided circumferentially of the boss structure 310, and the compression portion 212 abuts against the boss structure 310; the valve plate control assembly 200 also includes a guide member 220, a limiting portion 221 is provided at one end of the guide member 220, the limiting portion 221 cooperates with the limiting groove 311 and the limiting portion 221 can move relative to the limiting groove 311 toward the first end 120, and the other end of the guide member 220 is connected to the rebound valve plate 210.

[0046] In this embodiment, the researchers set up a boss structure 310, wherein the boss structure 310 can, on the one hand, be pressed against the compression portion 212 of the rebound valve plate 210, so that the compression portion 212 can be compressed and deformed after being subjected to force; on the other hand, the limit groove 311 set in the boss structure 310 can guide the moving direction of the guide member 220 in the valve plate control assembly 200, and at the same time limit the circumferential rotation of the guide member 220.

[0047] Specifically, when an external force acts on the valve plate control assembly 200, the compression portion 212 is in a compressed state, and the guide portion in the guide member 220 moves relative to the limiting groove 311 toward the first end 120. When the guide portion moves along the limiting groove 311 toward the first end 120, the guide portion is simultaneously restricted by the limiting groove 311 for circumferential rotation; when the external force acting on the valve plate control assembly 200 disappears, the compression portion 212 recovers its deformation, and the compression portion 212 drives the sealing portion 211 and the guide member 220 to move. At this time, the guide portion in the guide member 220 moves again along the limiting groove 311 toward the direction away from the first end 120, and is simultaneously restricted by the limiting groove 311 for circumferential rotation. In this way, it can be achieved that the sealing portion 211 in the rebound valve plate 210 can accurately block the second end 130.

[0048] Further, in one embodiment, see Figure 2 As shown, a groove structure is provided inside the sealing portion 211, wherein the shape of the groove structure can be a ring or other polygonal structure, and the guide member 220 is provided with a support portion 222, which is cooperatively connected with the groove structure.

[0049] In this embodiment, the researchers set a groove structure inside the sealing part 211 and set a support part 222 on the guide part. The support part 222 cooperates with the groove structure to support the sealing part 211, thereby reducing the risk of the sealing part 211 being difficult to seal the second end 130 of the shell 100 due to deformation.

[0050] In one embodiment, see Figure 4 and Figure 5 As shown, the pressing portion 140 is close to the middle of the second end 130 and extends in a direction away from the inner cavity 110; alternatively, the pressing portion 140 includes a first pressing sheet 141 and a second pressing sheet 142 that are spaced apart, and both the first pressing sheet 141 and the second pressing sheet 142 extend in a direction away from the inner cavity 110.

[0051] In this embodiment, the researchers set the pressing part 140 in the middle near the second end 130 or include the pressing part 140 in a first pressing plate 141 and a second pressing plate 142. The reason is that when the control valves are connected, the positions of the pressing parts 140 of the two control valves are different, thereby preventing the pressing parts 140 from interfering with each other when the two are connected.

[0052] In one embodiment, see Figure 4 As shown, the extension direction of the channel 150 is inclined with respect to the axial direction of the housing 100 .

[0053] In this embodiment, the researchers improved the structure of the channel 150. In one mode, the extension direction of the channel 150 is inclined with respect to the axial direction of the shell 100. For example, the angle between the extension direction of the channel 150 and the axial direction of the shell 100 is an acute angle, an obtuse angle or a right angle, etc. The specific angle size can be designed and adjusted according to actual conditions, so as to change the direction of the fluid after passing through the control valve, so that the control valve can better adapt to the pipeline design in the beverage equipment.

[0054] In another embodiment, see Figure 5 As shown, the cross-sectional area of ​​the end of the channel 150 away from the housing 100 is larger than the cross-sectional area of ​​the end close to the housing 100 .

[0055] In this embodiment, the cross-sectional area of ​​the end away from the housing 100 is larger than the cross-sectional area of ​​the end close to the housing 100 , and the channel 150 is funnel-shaped, which is conducive to liquid entering the channel 150 .

[0056] In one embodiment, see Figure 3 As shown, the housing 100 is provided with a card slot 160 or a card buckle 170. When two control valves are docked, the control valve provided with the card slot 160 can be card-engaged with the control valve provided with the card buckle 170.

[0057] In this embodiment, the researchers set a slot 160 or a buckle 170 on the housing 100, the purpose of which is to keep the two control valves connected and fixed when docking, so that the two control valves maintain a connected state. The slot 160 can be located outside or inside the housing 100.

[0058] In one embodiment, see Figure 3 As shown, the second end 130 is provided with a sealing sleeve 180 .

[0059] In this embodiment, the researchers set a sealing sleeve 180 at the second end 130, so that the connection between the two control valves has better sealing when docking, reducing the risk of fluid leakage at the connection.

[0060] The present application also proposes a control valve unit, see Figure 2 , Figure 3 and Figure 6 As shown, it includes the above-mentioned control valve, and the control valve unit includes two control valves. When the two control valves are connected, the pressing portion 140 in each control valve can press the valve plate control member of the other control valve so that the valve plate control component 200 of each control valve opens the respective second end 130; when the two control valves are separated, the valve plate control component 200 of each control valve blocks the respective second end 130.

[0061] In this embodiment, the control valve unit can realize the conduction function between the two control valves when docking, and each control valve returns to the cut-off state when separating.

[0062] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
