[0035] As described in the background, in the design of beverage equipment, in order to meet the needs of different scenes, it is usually necessary to introduce multiple fluids into the pipeline. The prior art usually sets up independent valves respectively in each fluid outlet direction to control the pipeline. However, this design increases the complexity of pipeline connection and valve control, and at the same time reduces the convenience of liquid dynamic switching and cleaning operation between different pipelines, which is not conducive to the overall optimization of the beverage equipment system and the improvement of maintenance efficiency. Therefore, the researchers in the present application propose a control joint, through which the dynamic switching control of fluids in different outlet directions can be realized, so as to improve the control efficiency and simplify the cleaning process.

[0036] As shown in FIG. 1, the control joint 1 comprises a valve body 10, a valve core 20 and a valve cover 30. Figure 1 As shown in FIG. 1, the control joint 1 comprises a valve body 10, a valve core 20 and a valve cover 30. Figure 1The figure shows the structure of a control joint in an embodiment of the present application. The control joint comprises a main pipe 100 and a valve piece control member 300. The main pipe 100 is provided with a pressing portion 110 at one end, and the side wall of the main pipe 100 near the pressing portion 110 is provided with a liquid inlet channel 120. The side wall of the main pipe 100 away from the pressing portion 110 is provided with a liquid outlet channel 130. The valve piece control member 300 is used to control the opening or closing of the liquid outlet channel 130. In this embodiment, by moving the main pipe 100, the pressing portion 110 in the main pipe 100 cooperates with a piston 400 in another control joint, so that the liquid inlet channel 120 on the side wall of the main pipe 100 communicates with a different channel in the side wall of the other control joint, thereby realizing dynamic switching of the fluid passage. At the same time, when the main pipe 100 is removed from the other control joint, the control joint can be directly cleaned.

[0037] Specifically, as shown in Figure 1 the main pipe 100 is provided with a pressing portion 110 at one end, the side wall of the main pipe 100 near the pressing portion 110 is provided with a liquid inlet channel 120, and the side wall of the main pipe 100 away from the pressing portion 110 is further provided with a liquid outlet channel 130. When the pressing portion 110 moves, it can press the piston 400 in another control joint and make the liquid inlet channel 120 communicate with a different channel in the pipe wall of the other control joint. The valve piece control member 300 is used to control the opening or closing of the liquid outlet channel 130.

[0038] In this embodiment, when the control joint in this embodiment is used, the pressing portion 110 of the main pipe 100 of the control joint in this embodiment is docked with another control joint. The other control joint is provided with a piston 400, and the pipe wall of the other control joint is provided with channels. When the pressing portion 110 of the control joint in this embodiment is docked with the other control joint, as shown in Figure 2 and Figure 3 the pressing portion 110 of the main pipe 100 can push the piston 400 to move. When the piston 400 is located to the right of one of the channels, for example, to the right of channel A, the liquid inlet channel 120 communicates with channel A, thereby realizing the entry of the liquid in channel A into the liquid inlet channel 120. When the piston 400 continues to be pressed, for example, when the piston 400 is located to the right of channel B, the side wall of the main pipe 100 can block channel A at this time. When the liquid inlet channel 120 moves to be docked with channel B, the liquid inlet channel 120 can communicate with channel B. That is, during the movement of the main pipe 100, the switching between channel A or channel B of the other control joint can be automatically realized. When the liquid enters the main pipe 100, the valve piece control member 300 opens the liquid outlet channel 130, thereby making the liquid outlet through the liquid outlet channel 130.

[0039] In addition, when the main pipe 100 needs to be cleaned, the main pipe 100 can be directly pulled out from another control joint for cleaning the control joint.

[0040] In an embodiment, referring to Figure 4 The valve piece control 300 includes a sealing portion 310 and a reciprocating control 320 for driving the sealing portion 310 to open or close the liquid discharge passage 130.

[0041] In the present embodiment, the valve piece control 300 includes a sealing portion 310 and a reciprocating control 320, wherein the reciprocating control 320 is responsible for driving the sealing portion 310 to move along a specified path to open or close the liquid discharge passage 130. The structure of the reciprocating control 320 allows the sealing portion 310 to be accurately positioned, ensuring that the liquid discharge passage 130 can be quickly opened when liquid discharge is required, thereby facilitating the discharge of liquid. Conversely, when liquid discharge is not required, the sealing portion 310 can effectively close the liquid discharge passage 130 to prevent liquid leakage or reverse flow. It should be noted that the reciprocating control 320 can be achieved through electric control, mechanical force or magnetic force.

[0042] Further, in an embodiment, referring to Figure 4 The liquid discharge passage 130 is provided with a moving cavity 160 near the inner cavity side of the main pipe 100, and the sealing portion 310 cooperates with the moving cavity 160 to open or close the liquid discharge passage 130.

[0043] In the present embodiment, the liquid discharge passage 130 is provided with a moving cavity 160 near the inner cavity side of the main pipe 100, wherein the moving cavity 160 is designed to guide the movement of the sealing portion 310 to open or close the liquid discharge passage 130. Through cooperation with the moving cavity 160, the sealing portion 310 can be accurately positioned and moved along a specific path, thereby ensuring that the liquid discharge passage 130 is opened when required, and vice versa when liquid discharge is not required.

[0044] In an embodiment, referring to Figure 5 The sealing portion 310 includes a first sealing segment 311, a second sealing segment 312 and a third sealing segment 313, the cross-sectional area of the first sealing segment 311 is smaller than that of the moving cavity 160, the second sealing segment 312 connects the first sealing segment 311 and the third sealing segment 313, and the cross-sectional area of the third sealing segment 313 is larger than that of the moving cavity 160.

[0045] In the embodiment, the first sealing section 311 is capable of moving along the moving cavity 160, thereby realizing the guidance with the moving cavity 160. The cross-sectional area of the first sealing section 311 is smaller than that of the moving cavity 160, so that the first sealing section 311 is capable of moving in the first moving cavity 160, thereby realizing the accurate guidance of the sealing part 310. When the first sealing section 311 moves out of the moving cavity 160, the liquid discharge channel 130 is opened, thereby enabling the liquid to be discharged through the liquid discharge channel 130. Meanwhile, the cross-sectional area of the third sealing section 313 is larger than that of the moving cavity 160, so that when the third sealing section 313 abuts against the side of the moving cavity 160 close to the inner cavity of the second sectional pipe, the moving cavity 160 is effectively isolated from the inner cavity of the second sectional pipe, and the liquid discharge channel 130 is completely closed, thereby preventing the liquid from leaking or backflowing.

[0046] In an embodiment, referring to Figure 4 As shown in the figure, the side wall of the main pipe 100 is provided with a mounting channel 170, the extension direction of the mounting channel 170 coincides with the center line of the moving cavity 160, and the reciprocating control member 320 is arranged in the mounting channel 170.

[0047] In the embodiment, the side wall of the main pipe 100 is provided with a mounting channel 170, wherein the extension direction of the mounting channel 170 coincides with the center line of the moving cavity 160, so that the reciprocating control member 320 is capable of moving along the center line of the moving cavity 160, thereby ensuring that the driving action of the reciprocating control member 320 on the sealing part 310 is completely consistent with the guidance direction of the moving cavity 160, so as to avoid the unstable movement or inaccurate positioning of the sealing part 310 due to the direction deviation.

[0048] In an embodiment, referring to Figure 4 and Figure 5 As shown in the figure, the reciprocating control member 320 comprises a support member 321, an elastic member 322 and a mounting seat 323. The support member 321 is connected with the sealing part 310, the elastic member 322 is arranged between the mounting seat 323 and the support member 321, and when the elastic member 322 is subjected to a force, the support member 321 is driven to move the sealing part 310. The elastic member 322 can be a spring.

[0049] In the embodiment, one end of the support 321 is connected with the sealing part 310, and the other end is in contact with the elastic part 322, thereby forming a transmission structure for driving the sealing part 310 to move. The elastic part 322 is arranged between the mounting seat 323 and the support 321, and the driving force of the support 321 is transmitted through the deformation of the elastic part 322, thereby driving the sealing part 310 to move along a set path to realize the opening or closing of the drainage passage 130. Specifically, when an external force acts on the elastic part 322, the elastic part 322 is compressed, and the driving force is transmitted to the sealing part 310 through the support 321, so that the sealing part 310 moves away from the drainage passage 130 to complete the opening operation of the drainage passage 130. When the external force is released, the elastic part 322 restores the deformation, pushes the support 321 to move reversely, and drives the sealing part 310 to move to the position close to the drainage passage 130, thereby realizing the closing operation of the drainage passage 130.

[0050] In an embodiment, referring to Figure 4 , one end of the support 321 towards the elastic part 322 is provided with a mounting groove, and a magnetic part 324 is arranged in the mounting groove. When the magnetic part 324 is subjected to a magnetic attraction force, the support 321 can be driven to reciprocate; and / or, the main pipeline 100 comprises a first branch pipeline 210 and a second branch pipeline 220. The first branch pipeline 210 extends in a first direction, and the second branch pipeline 220 extends in a second direction. The inlet passage 120 is arranged in the first branch pipeline 210, and the drainage passage 130 is arranged in the second branch pipeline 220. The first direction can be a horizontal direction, and the second direction can be a vertical direction. Figure 4 Figure 4

[0051] In the embodiment, one end of the support 321 is provided with a mounting groove, and a magnetic part 324 is arranged in the mounting groove. When the magnetic part 324 is subjected to a magnetic attraction force of an external magnetic field, the support 321 is driven to move in the compression direction of the elastic part 322, thereby driving the sealing part 310 to move away from the position of the drainage passage 130 to complete the opening operation of the drainage passage 130. When the external magnetic field is removed, the magnetic part 324 is no longer subjected to the magnetic attraction force, and the elastic part 322 drives the support 321 to move reversely through the reset deformation, and the sealing part 310 returns to the position close to the drainage passage 130 to realize the closing operation of the drainage passage 130. Through the cooperation of the magnetic part 324 and the external magnetic field, non-contact force transmission driving is realized.

[0052] ​​In addition, the main pipe 100 comprises a first branch pipe 210 extending in a first direction and a second branch pipe 220 extending in a second direction. The liquid inlet passage 120 is arranged in the first branch pipe 210, and the liquid outlet passage 130 is arranged in the second branch pipe 220. Through such a branch pipe design, the flow direction of the liquid entering the main pipe 100 can be effectively changed to adapt to the liquid flow requirements in different scenarios, thereby realizing flexible switching and control of the liquid flow direction.

[0053] In another embodiment, referring to Figure 6 As shown, the reciprocating control member 320 comprises a support member 321 connected with the sealing part 310 and a rotating member 330 comprising a first end 331 and a second end 332. The rotating member 330 is rotationally connected with the main pipe 100, the second end 332 is connected with the support member 321, and when the first end 331 is subjected to an external force, the rotating member 330 rotates, and the second end 332 drives the support member 321 to move in a direction away from the liquid outlet passage 130, so that the sealing part 310 moves away from the liquid outlet passage 130.

[0054] In this embodiment, the reciprocating control member 320 comprises a support member 321 connected with the sealing part 310 and a rotating member 330. The first end 331 and the second end 332 of the rotating member 330 are located on both sides of the fulcrum at which the rotating member 330 is rotationally connected with the main pipe 100. When an external force is applied to the first end 331 of the rotating member 330, the rotating member 330 rotates around the fulcrum, and the second end 332 of the rotating member 330 pushes the support member 321 to move in a direction away from the liquid outlet passage 130, so that the sealing part 310 moves to open the liquid outlet passage 130. In this embodiment, the force transmission mechanism based on the lever principle converts the external force into the linear motion of the support member 321, thereby realizing the opening and closing operation of the liquid outlet passage 130. When the external force is removed, the rotating member 330 rotates back under the action of the reset mechanism, and the support member 321 drives the sealing part 310 to reset to a position in which the liquid outlet passage 130 is closed, thereby blocking the liquid flow path.

[0055] In one embodiment, referring to Figure 6 and Figure 7 As shown, the first end 331 extends in an inclined direction, and the second end 332 extends in a direction parallel to the axis of the main pipe 100; and / or, the shape of the liquid inlet passage 120 is a long circular hole; and / or, the front end of the pressing part 110 has a tapered structure; and / or, at least one sealing ring 140 is arranged on the outer wall of the liquid inlet passage 120 away from the pressing part 110.

[0056] In the embodiment, the first end 331 of the rotating member 330 extends in the inclined direction, and the second end 332 extends in parallel with the axis of the main pipe 100. When an external force acts on the first end 331, the rotating motion of the rotating member 330 is converted into the linear motion of the supporting member 321 through the second end 332, so that the sealing part 310 is displaced in the direction away from the drainage passage 130, and the opening operation of the drainage passage 130 is completed.

[0057] The liquid inlet passage 120 adopts a long circular hole structure, and the shape design of the long circular hole can enhance the adaptation capability to different specifications of external interfaces and reduce the risk of docking failure caused by the size difference of the hole. The front end of the pressing part 110 is provided with a tapered structure, and the geometric characteristics of the tapered structure can guide the main pipe 100 and the pipe of another control joint to be quickly aligned during docking, reducing the positioning deviation during docking. At least one sealing ring 140 is arranged at the outer wall of the liquid inlet passage 120 away from the pressing part 110, and the arrangement of the sealing ring 140 can improve the sealing performance between the liquid inlet passage 120 and the external interface, preventing liquid leakage during transmission.

[0058] The application also provides a beverage equipment, wherein the beverage equipment comprises the control joint.

[0059] In the embodiment, by arranging the control joint in the beverage equipment, the communication between the liquid inlet passage 120 and different pipes can be automatically realized, avoiding the system complexity caused by the dependence on multiple pipes and valve control in the prior art. At the same time, after the first segmented pipe is removed from another control joint, the control joint can be directly cleaned, simplifying the cleaning operation and improving the convenience and efficiency of the later maintenance.

[0060] The technical features of the above embodiments can be combined arbitrarily. In order to make the description simple, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.

[0061] The above embodiments only express several implementation manners of the application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the application, some modifications and improvements can be made, which are all within the protection scope of the application.
