Description

Technical Field

[0001] This utility model relates to the technical field of liquid discharge devices, and in particular to a liquid discharge component. Background Technology

[0002] The existing drain valve body is directly welded to the outlet pipe, and the outlet pipe is fixed relative to the valve body. Although welding the drain valve body and outlet pipe together makes manufacturing simpler, it lacks flexibility in terms of assembly, use, and adjustment of the outlet direction.

[0003] For example, some beverage making equipment uses boilers to heat water or generate steam to make milk foam; the boiler is equipped with a drain valve for discharging liquid. The existing drain valve body is directly welded to the drain pipe, and the water outlet direction of the drain pipe cannot be adjusted. In terms of equipment layout, it also restricts the freedom of pipe connection, resulting in longer pipes and reduced water output efficiency.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

The connecting port is located on the upstream side of the second discharge channel, and the valve body is provided with a through hole for connecting the first discharge channel and the second discharge channel.

[0010] A flow-blocking component is slidably connected to the valve body. The flow-blocking component moves along the first discharge channel toward or away from the connection port to close or open the connection port.

[0011] As described above, a liquid discharge assembly includes a discharge pipe and a sleeve disposed on one side of the discharge pipe, the sleeve being rotatably connected to the valve body; the second discharge channel includes a first branch disposed within the sleeve and a second branch disposed within the discharge pipe, the first branch and the second branch having a preset included angle.

[0012] As described above, in a liquid discharge assembly, the valve body has a rotating groove on its outer side for the sleeve to rotate, and a contact surface on the inner side of the rotating groove. The sleeve is fitted over the contact surface. A through hole is provided on the contact surface and communicates with the first discharge channel and the second discharge channel. The valve body also has a first positioning part located on one side of the rotating groove, and a first limiting member opposite to the first positioning part is fitted over the outer side of the valve body. The sleeve is positioned by the first positioning part and the first limiting member.

[0013] As described above, in a liquid discharge assembly, the contact surface includes at least a first contact surface and a second contact surface, the first contact surface and the second contact surface are arranged opposite to each other along the axial direction of the valve body, and the valve body is further provided with a connecting wall located between the first contact surface and the second contact surface; a plurality of through holes are provided, each of the through holes being evenly distributed along the circumference of the connecting wall, and each of the through holes being radially disposed in the connecting wall and communicating with the rotating groove.

[0014] In a liquid discharge assembly as described above, at least one first sealing ring is provided between the sleeve and the contact surface, and the first sealing ring is located on one side of the through hole.

[0015] As described above, a liquid discharge assembly includes a valve stem disposed within the valve body and a flow-stopping plug disposed at one end of the valve stem. The valve stem has a mounting cavity for installing the flow-stopping plug, which is used to close the communication port. The valve body has a second positioning part located above the through hole, and the communication port passes through the second positioning part and communicates with the first discharge channel. The second positioning part is used to limit the insertion distance of the valve stem within the valve body.

[0016] In a liquid discharge assembly as described above, the valve stem has a third positioning part at the end away from the throttling plug. The third positioning part is opposite to the valve body and is used to limit the extension distance of the valve stem within the valve body.

[0017] The liquid discharge assembly described above further includes a second limiting member detachably connected to the valve body. The valve stem has a limiting groove corresponding to the second limiting member on its outer side. The second limiting member passes through the valve body and extends into the limiting groove.

The discharge component can rotate axially relative to the valve body under force, and the discharge component rotates to connect with the second discharge channel and the through hole to the first discharge channel to realize the discharge function of the liquid discharge assembly. At the same time, the discharge direction of the second discharge channel is adjusted. Moreover, when the discharge component is used in the equipment, the direction can be adjusted according to the equipment layout during assembly, which is beneficial to improve the installation flexibility of the liquid discharge assembly and to shorten the internal pipeline connection of the equipment, thereby improving the discharge efficiency.

[0035] Example 1:

[0036] like Figure 1As shown in Figure 8, this utility model provides a liquid discharge assembly, including a valve body 1, a discharge component 2, and a flow-stopping component 3. The valve body 1 has a first discharge channel 101 with a connecting port 102. The discharge component 2 is rotatably disposed outside the valve body 1 and has a second discharge channel 20 within it. The connecting port 102 is located upstream of the second discharge channel 20. The valve body 1 has a through hole 103 for connecting the first discharge channel 101 and the second discharge channel 20. The flow-stopping component 3 is slidably connected within the valve body 1 and moves along the first discharge channel 101 towards or away from the connecting port 102 to close or open the connecting port 102. In this embodiment, the first discharge channel 101 extends longitudinally through the valve body 1 and is used to receive liquid. The connecting port 102 and the through hole 103 are sequentially arranged from top to bottom in the valve body 1. The connecting port 102 is located inside the valve body 1, and the through hole 103 is located on the side wall of the valve body 1. The connecting port 102 connects to the first discharge channel 101, and the through hole 103 connects to the first discharge channel 101 and the second discharge channel 20 to form a smooth discharge channel. The flow-blocking component 3 is located inside the valve body 1 and below the connecting port 102. In practical applications, the flow-blocking component 3 can move along the first discharge channel 101 towards or away from the connecting port 102 under force, such as... Figure 5 As shown, when the flow-blocking component 3 moves along the first discharge channel 101 near the connecting port 102, the flow-blocking component 3 can abut against the valve body 1 to close the connecting port 102, thereby blocking the first discharge channel 101 and the second discharge channel 20, thus restricting the liquid discharge of the liquid discharge component; Figure 4As shown, when the flow-stopping component 3 moves away from the connecting port 102 along the second discharge channel 20, the connecting port 102 is opened, thereby connecting the first discharge channel 101 and the second discharge channel 20. At this time, the liquid discharge component can discharge liquid, that is, the liquid flowing into the valve body 1 flows along the first discharge channel 101, and flows sequentially through the connecting port 102 and the through hole 103 into the second discharge channel 20, and flows along the second discharge channel 20 to the outside of the liquid discharge component. The second discharge channel 20 can be connected to a pipeline to... Further liquid is discharged; in addition, the discharge component 2 can be axially rotated relative to the valve body 1 under force, and the discharge component 2 rotates to the second discharge channel 20, and the through hole 103 is connected to the first discharge channel 101 to realize the liquid discharge function of the liquid discharge assembly. At the same time, the discharge direction of the second discharge channel 20 is adjusted. Moreover, when the discharge component 2 is used in the equipment, the direction can be adjusted according to the equipment layout during assembly, which is beneficial to improve the installation flexibility of the liquid discharge assembly and to shorten the internal pipeline connection of the equipment, thereby improving the discharge efficiency.

[0037] Optionally, in practical applications, such as Figure 8 As shown, the liquid discharge assembly is at least used in beverage preparation equipment. The liquid discharge assembly is located on one side of the boiler and is used to discharge hot water from the boiler. Optionally, to further accelerate the water output speed and ensure water output, the liquid discharge assembly can be installed at the bottom of the boiler. It should be noted that the liquid discharge assembly can also be used in water purifiers, water heaters, and other equipment requiring water output, changing the water output direction to achieve multi-angle water output for user convenience.

[0038] like Figure 7As shown, in some optional embodiments, the discharge component 2 includes a drain pipe 21 and a sleeve 22 disposed on one side of the drain pipe 21. One end of the drain pipe 21 can be connected to an additional pipeline for flow guidance. The discharge component 2 is rotatably connected to the valve body 1 through the sleeve 22. The drain pipe 21 can rotate relative to the valve body 1 under force through the sleeve 22. The second discharge channel 20 includes a first branch 201 disposed in the sleeve 22 and a second branch 202 disposed in the drain pipe 21. The first branch 201 and the second branch 202 have a preset included angle. In this embodiment, the drain pipe 21 is along the sleeve One side of the sleeve 22 extends outward. The first branch 201 is inserted into the sleeve 22 along the axial direction of the sleeve 22, and the second branch 202 is inserted into the drain pipe 21 along the axial direction of the drain pipe 21. There is a preset angle between the first branch 201 and the second branch 202, that is, there is a preset angle between the central axis of the sleeve 22 and the central axis of the drain pipe 21. The preset angle can be set according to the specific installation layout of the liquid discharge assembly, which is beneficial to further expand the adjustment range of the drain direction of the drain pipe 21 and further improve the assembly flexibility of the liquid discharge assembly; preferably, the preset angle is 90°.

[0039] like Figure 3As shown, in some optional embodiments, the outer side of the valve body 1 is provided with a rotating groove 104 for the sleeve 22 to rotate, the inner side of the rotating groove 104 is provided with a contact surface 11, and the sleeve 22 is sleeved on the outside of the contact surface 11; the through hole 103 is provided on the contact surface 11 and communicates with the first discharge channel 101 and the second discharge channel 20; the valve body 1 is also provided with a first positioning part 12 located on one side of the rotating groove 104, and the outer side of the valve body 1 is also sleeved with a first limiting member 4 opposite to the first positioning part 12, and the sleeve 22 is positioned by the first positioning part 12 and the first limiting member 4; in this embodiment, the outer wall of the valve body 1 is radially recessed to form the rotating groove 104, and the contact surface 11 is formed on the inner side of the rotating groove 104, and the first positioning part 12 is formed on the upper side of the rotating groove 104, and the through hole 103 is provided on the outer side of the rotating groove 104. 03 is radially disposed on the contact surface 11 to enable communication between the first discharge channel 101 and the second discharge channel 20; optionally, the rotating groove 104 is an annular groove, which provides rotation space for the sleeve 22; during assembly, the sleeve 22 is rotatably sleeved on the outside of the contact surface 11, and the first limiting member 4 is sleeved on the valve body 1 and located on the lower side of the sleeve 22, so that the sleeve 22 is positioned between the first positioning part 12 and the first limiting member 4, thereby improving the connection stability of the sleeve 22 and shortening the communication path formed by the second discharge channel and the through hole 103, thereby improving the discharge efficiency of the liquid; on the other hand, the first limiting member 4 can be a limiting nut, and the first limiting member 4 is threadedly connected to the valve body 1 to facilitate the disassembly and replacement of the discharge component 2.

[0040] Further optionally, to improve the drainage efficiency of the liquid discharge assembly, such as... Figure 3 As shown, a plurality of through holes 103 are provided, and each through hole 103 is evenly distributed along the circumference of the contact surface 11. In practical applications, when the drain pipe 21 is subjected to force and rotates relative to the valve body 1 through the sleeve 22, regardless of the rotation angle, it has a corresponding through hole 103 to directly connect the first discharge channel 101 and the second discharge channel 20, which can further ensure the normal discharge of the liquid discharge component. At the same time, it further shortens the connection path between the second discharge channel 20 and the corresponding through hole 103, thereby improving the discharge efficiency.

[0041] In some alternative embodiments, to prevent water leakage between the sleeve 22 and the valve body 1, at least one first sealing ring 5 is provided between the sleeve 22 and the contact surface 11, and the first sealing ring 5 is located on one side of the through hole 103; optionally, the sleeve 22 and / or the valve body 1 are provided with a first mounting groove, and the first sealing ring 5 is fitted and connected in the first mounting groove, and abuts against the sleeve 22 and the valve body 1 through the first sealing ring 5, so as to improve the sealing between the sleeve 22 and the valve body 1 and improve the drainage efficiency of the liquid discharge assembly; and by using the mounting groove to assemble the first sealing ring 5, the assembly between the sleeve 22 and the valve body 1 can be more compact, which is beneficial to reducing the volume of the liquid discharge assembly.

[0042] In other alternative embodiments, such as Figure 4 and Figure 5 As shown, the flow-blocking assembly 3 includes a valve stem 31 disposed within the valve body 1 and a flow-blocking plug 32 disposed at one end of the valve stem 31. The top of the valve stem 31 has a mounting cavity 312 for mounting the flow-blocking plug 32. The flow-blocking plug 32 is fixedly disposed within the mounting cavity 312 and is used to close the communication port 102. The valve body 1 has a second positioning portion 14 located above the through hole 103. The inner wall of the valve body 1 extends radially towards its central axis to form the second positioning portion 14. The communication port 102 passes through the second positioning portion 14 and communicates with the first discharge channel 101. The second positioning portion 14 is used to limit the insertion distance of the valve stem 31 within the valve body 1. In practical applications, the valve stem 31, under force, can extend and retract relative to the valve body 1 along the first discharge channel 101, causing the flow-blocking plug 32 to move away from or towards the connection port. Specifically, when the valve stem 31 extends outward relative to the valve body 1, the flow-blocking plug 32 moves away from the connection port. The connecting port 102 moves to open, thereby connecting the first discharge channel 101, the connecting port 102, the through hole 103, and the second discharge channel 20, allowing the liquid discharge assembly to discharge normally. When the valve stem 31 retracts inward relative to the valve body 1, the shut-off plug 32 moves close to the connecting port to abut against the second positioning part 14, closing the connecting port 102 and blocking the connection between the first discharge channel 101 and the second discharge channel 20, thus restricting the liquid discharge of the liquid discharge assembly. Optionally, the second positioning part 14 is located close to the through hole 103 and above the through hole 103, thereby adjusting the position of the connecting port 102 within the valve body 1, shortening the distance between the connecting port 102 and the through hole 103, and increasing the liquid discharge speed. By limiting the insertion distance of the valve stem 31 within the valve body 1 through the second positioning part 14, the normal use of the liquid discharge assembly can be ensured.

[0043] In other alternative embodiments, to further improve the stability of the liquid discharge assembly, such as... Figure 5 As shown, the valve stem 31 has a third positioning part 311 at the end away from the throttling plug 32, that is, the valve stem 31 has the third positioning part 311 at the bottom. The third positioning part 311 extends radially outward from the outer wall of the valve stem 31. The third positioning part 311 is opposite to the valve body 1 and is used to limit the insertion distance of the valve stem 31 in the valve body 1. When the valve stem 31 retracts inward relative to the valve body 1, the valve stem 31 moves until the third positioning part 311 abuts against the valve body 1, and at the same time the throttling plug 32 abuts against the second positioning part 14 to close the communication port 102.

[0044] In other alternative embodiments, to further improve the stability of the liquid discharge assembly, such as... Figure 2 , 4 As shown in Figure 5, the liquid discharge assembly further includes a second limiting member 6 detachably connected to the valve body 1. Optionally, the valve body 1 is provided with an assembly hole 16 adapted to the second limiting member 6; the outer side of the valve stem 31 is provided with a limiting groove 313 corresponding to the second limiting member 6. Optionally, the limiting groove 313 is located near the third positioning part 311, and the limiting groove 313 extends along the axial direction of the valve stem 31. The second limiting member 6 passes through the valve body 1 and extends into the limiting groove 313. In practical applications, the limiting groove 313 has opposing upper sidewalls 3131 and lower sidewalls 3132 on both sides. The second limiting member 6 passes through the assembly hole 16 into the valve body 1 and extends into the limiting groove 313. The second limiting member 6 is opposite to the upper sidewalls 3131 and lower sidewalls 3132. Figure 4 As shown, when the valve stem 31 extends outward relative to the valve body 1 along the first discharge channel 101, the upper sidewall 3131 abuts against the second limiting member 6 to limit the extension distance of the valve stem 31, thereby improving the movement stability and movement efficiency of the valve stem 31, and thus improving the discharge efficiency of the liquid discharge assembly; wherein, the lower sidewall 3132 may be the upper end face of the third positioning part 311; in addition, when the second limiting member 6 extends radially to abut against the valve stem 31, the valve stem 31 can be fixed inside the valve body 1. Optionally, the second limiting member 6 is a limiting screw, and the mounting hole 16 can be correspondingly set as an internal thread hole, which is simple in structure and easy to implement.

[0045] In other alternative embodiments, such as Figure 4As shown, a second sealing ring 7 is also provided between the valve stem 31 and the valve body 1. The second sealing ring 7 is located below the through hole 103 and abuts against the valve stem 31 and the valve body 1 to prevent water leakage. In addition, the second sealing ring 7 can be made of a high-temperature resistant flexible material to ensure the telescopic movement of the valve stem 31 relative to the valve body 1. Further optionally, a second mounting groove for installing the second sealing ring 7 is provided between the valve stem 31 and the valve body 1. For example, the second mounting groove is provided on the outer wall of the valve stem 31 or the inner wall of the valve body 1, making the connection between the valve stem 31 and the valve body 1 more compact and enhancing the tightness of the connection between the valve stem 31 and the valve body 1.

[0046] In other alternative embodiments, such as Figure 1 and Figure 4 As shown, the liquid discharge assembly further includes a connector 8 disposed on one side of the valve body 1. The connector 8 is used to install the liquid discharge assembly in the main body of the equipment. Optionally, the liquid discharge assembly is installed at the bottom of the boiler through the connector 8 for discharging liquid in the boiler. Further, the connector 8 is provided with a third discharge channel 81 communicating with the first discharge channel 101. A third sealing ring 9 is provided between the connector 8 and the valve body 1. The specific installation of the third sealing ring 9 can refer to the first sealing ring 5 and the second sealing ring 7, which will not be described in detail here. In this embodiment, the third discharge channel 81 is axially disposed through the connector 8. The valve body 1 is provided with an extension 15 located above the second positioning part 14. The extension 15 extends upward axially. At least part of the connector 8 extends into the inside of the extension 15. The third sealing ring 9 is disposed between the extension 15 and the connector 8 to prevent water leakage. Optionally, for ease of disassembly and replacement, the connector 8 and the extension 15 are detachable connections such as threaded connection, snap-fit, or plug-in connection.

[0047] Further optionally, in order to improve the connection stability between the connector 8 and the valve body 1, a fourth positioning part 82 is provided on the outside of the connector 8 to position the installation position of the valve body 1, and the third sealing ring 9 is located on the lower side of the fourth positioning part 82.

[0048] Example 2:

[0049] The difference between this embodiment 2 and embodiment 1 is that, Figure 2 , 4As shown in Figure 5, the contact surface 11 includes at least a first contact surface 11a and a second contact surface 11b. The first contact surface 11a and the second contact surface 11b are arranged opposite each other along the axial direction of the valve body 1. The valve body 1 is also provided with a connecting wall 13 located between the first contact surface 11a and the second contact surface 11b. The connecting wall 13 is located inside the first contact surface 11a and the second contact surface 11b. A plurality of through holes 103 are provided. Each through hole 103 is evenly distributed along the circumference of the connecting wall 13, and each through hole 103 is radially inserted into the connecting wall 13 and communicates with the rotating groove 104. In this embodiment, the sleeve 22 is sleeved on the outside of the first contact surface 11a and the second contact surface 11b, which helps to reduce the contact area 11 between the sleeve 22 and the valve body 1, and reduce the... The reduced friction force on the sleeve 22 during rotation improves its rotational performance. In practical applications, when the drain pipe 21 rotates relative to the valve body 1 under force through the sleeve 22, regardless of the rotation angle, it has corresponding through holes 103 to directly connect the first discharge channel 101 and the second discharge channel 20. This further ensures the normal drainage of the liquid discharge assembly, shortens the connection path between the second discharge channel 20 and the corresponding through hole 103, and improves the liquid discharge efficiency. At the same time, since each through hole 103 is connected to the rotating groove 104, the liquid in the first discharge channel 101 can also flow into the rotating groove 104 through other through holes 103. The liquid in the rotating groove 104 then flows out through the second discharge channel 20, which helps to improve the drainage efficiency.

Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
