Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0048] Please refer to Figures 1 to 8 , the pipeline integration module 100 provided by the present utility model can be applied in a hot water system, and the hot water system can be specifically applied in a beverage processing device.

[0049] It can be understood that the pipeline integration module 100 at least integrates one or several channel structures required by the hot water system or the beverage processing device. The hot water system generally further includes a hot water boiler 200. The hot water boiler 200 includes a boiler main body and, for example, heating devices, sensor devices, etc. provided inside the boiler main body. The beverage processing device includes a housing and various functional modules. At least part of the hot water system is housed inside the housing. The beverage processing device can be used to process raw materials such as coffee beans, soybeans, etc. and finally obtain beverages such as coffee liquid, soy milk, etc. Among them, the processing process can be, but is not limited to, grinding, brewing and extraction, etc. Therefore, the above-mentioned functional modules can be, but are not limited to, a grinding module, a brewing module, a milk supply module, etc.

[0050] Specifically, in actual applications:

[0051] The hot water system has a water inlet mode. In this mode, the boiler main body can be connected to an external cold water source through, for example, the preset channel structure in the pipeline integration module 100. The cold water source can be a water source outside the beverage processing device, such as a faucet fixedly installed in the environment where the beverage processing device is placed; the cold water source can also be a water source built into the beverage processing device, such as a cold water tank storing a certain volume of water.

[0052] The hot water system also has a heating mode. In this mode, the heating device inside the boiler main body starts to operate and heats the cold water to finally obtain hot water at the required temperature. The heating device can be selected according to actual needs, such as a resistance heating device, an infrared heating device, or an electromagnetic heating device, etc.

[0053] The hot water system also has a water outlet mode. In this mode, the boiler body can be connected to an external functional module through, for example, a channel structure preset in the pipeline integration module 100, so as to be able to supply hot water to the functional module. Among them, the functional modules that require hot water are, for example, but not limited to, a brewing module, a milk supply module, etc. Of course, the hot water system can also directly supply hot water to, for example, a beverage outlet outside the housing.

[0054] The hot water system also has a pressure relief mode. When the continuous operation of the heating device causes the pressure in the boiler body to exceed the preset threshold, a certain high pressure can be released to the outside through, for example, the pipeline integration module 100, so as to ensure that the pressure in the boiler body is stable within a suitable range and ensure the safe operation of the hot water system.

[0055] The hot water system also has a drainage mode. When the hot water system or the beverage cooking device as a whole needs to be stored, transported, etc., or when the ambient temperature is relatively low, the drainage mode of the hot water system can be started. In this mode, the boiler body can drain the residual water in it to the outside through, for example, the pipeline integration module 100, ensuring that the inside of the boiler body remains relatively dry and avoiding damage to the boiler body.

[0056] In view of the above, since the main improvement point of the present utility model lies in the pipeline integration module 100, the pipeline integration module 100 will be mainly described below with reference to the drawings.

[0057] Please refer to Figures 2 to 8 , in the pipeline integration module 100 of the present utility model, it includes a block body 110, a pressure relief valve body 120 and a plugging member. Among them, the block body 110 is respectively provided with a pressure relief channel 111, a waste discharge channel 112 and a drainage channel 114. One port of the pressure relief channel 111 penetrates the outer wall of the block body 110 and is used for communicating and connecting with the hot water boiler 200. The other port of the pressure relief channel 111 is communicated and connected with the drainage channel 114. The middle section of the pressure relief channel 111 is communicated and connected with the waste discharge channel 112. At least one port of the waste discharge channel 112 and / or the drainage channel 114 penetrates the outer wall of the block body 110; the pressure relief valve body 120 has a pressure maintaining state in which the pressure relief channel 111 and the waste discharge channel 112 are blocked when the pressure in the pressure relief channel 111 does not reach the first preset threshold, and a pressure relief state in which the pressure relief channel 111 and the waste discharge channel 112 are conducted when the pressure in the pressure relief channel 111 reaches the first preset threshold; the plugging member is movably installed in the drainage channel 114, and has a drainage position in which the pressure relief channel 111 and the drainage channel 114 are actively conducted and a partition position in which the pressure relief channel 111 and the drainage channel 114 are actively blocked under the drive of an external driving member.

[0058] In the technical solution provided by the present utility model, a pressure relief channel 111, a waste discharge channel 112, and a drain are integrally formed inside the block 110 in advance. On the one hand, this enables the block 110 to be more conveniently directly connected to the hot water boiler 200, or indirectly connected to the hot water boiler 200 through a joint structure, which helps to reduce the interlaced splicing between excessive pipe structures, thereby contributing to simplifying the overall structural design and disassembly and assembly operations. On the other hand, it makes the installation positions of each channel structure such as the pressure relief channel 111, the waste discharge channel 112, and the drain channel 114 fixed, which helps to avoid adverse situations such as mutual separation or force-induced deformation during use. In addition, when the plugging member is in the blocking position, the pressure relief valve body 120 can conduct the pressure relief channel 111 and the waste discharge channel 112 when the internal pressure of the hot water boiler 200 is too high, which helps to reduce the internal pressure of the hot water boiler 200, and can rely on features such as the structural strength of the block 110 to improve the safety of the pressure relief process and the service life of the pressure relief channel 111. The pressure relief valve body 120 can also ensure the formation of a seal between the pressure relief channel 111 and the inner cavity of the hot water boiler 200 when the internal pressure of the hot water boiler 200 is too low, which helps to form sufficient pressure in the hot water boiler 200 to ensure the normal operation of the hot water boiler 200. And when the plugging member is in the drain position, the waste water in the hot water boiler 200 can be discharged outward through the pressure relief channel 111 and the drain channel 114, which helps to maintain the quality of the hot water boiler 200 and ultimately helps to improve the overall reliability of the hot water system.

[0059] In this design, the block 110 generally refers to a three-dimensional structure with a certain length, width, and height. For the convenience of understanding, in the following embodiments, it is defined that the block 110 has a first direction, a second direction, and a third direction that are cross-set in pairs. Among them, when the first direction, the second direction, and the third direction are cross-set at 90° in pairs, they can roughly correspond to the length direction, the width direction, and the height direction of the block 110.

[0060] The block 110 can be a three-dimensional structure with a regular shape, such as a cylindrical shape, a polyhedral prism shape, etc. The block 110 can also be set as a three-dimensional structure with an irregular shape according to actual needs. As Figure 2 shown, in one embodiment, the block 110 is generally in the shape of a cuboid. When the block 110 is specifically installed in the housing of the beverage processing equipment, one of its first direction, second direction, and third direction (specifically, for example, the third direction) can correspond to the gravity direction.

[0061] Since the block 110 is a three-dimensional structure as described above, there is enough space reserved inside it for each channel structure to be opened. In this embodiment, at least a pressure relief channel 111, a waste discharge channel 112, and a drain channel 114 are opened inside the block 110.

[0062] Among them, the waste discharge channel 112 and the evacuation channel 114 can extend along the first direction respectively, and the two can be spaced apart in the second direction or the third direction, for example, so as to make full use of the limited space of the block 110.

[0063] Among them, at least one port of the waste discharge channel 112 penetrates the outer wall of the block 110 to form a waste discharge port. The waste discharge port can be directly or indirectly connected to an external container through a pipeline structure according to actual needs. The external container can be, but is not limited to, a water receiving tray fixedly arranged on the front side of the housing of the beverage processing device, or a waste residue box fixedly arranged inside the housing, etc.

[0064] Similarly, the evacuation channel 114 can also be directly or indirectly connected to an external container. Among them, the external container connected to the waste discharge channel 112 and the external container connected to the evacuation channel 114 can be the same container or two different containers. Specifically, in one embodiment, the waste discharge channel 112 and the evacuation channel 114 can be at least partially connected inside the block 110, and then the two are connected to the same external container. At this time, the evacuation channel 114 can be formed inside the block 110 but does not penetrate the outer wall of the block 110. Or in one embodiment, the waste discharge channel 112 and the evacuation channel 114 are independently arranged inside the block 110 and are connected to the same external container through a pipeline outside the block 110. At this time, at least one port of the evacuation channel 114 penetrates the outer wall of the block 110 (that is, Figure 8 the evacuation port 114d in).

[0065] The pressure relief channel 111 extends along the second direction. One port of the pressure relief channel 111 penetrates the outer wall of the block 110 to form a pressure relief port connected to an opening of the boiler main body. Among them, the opening of the boiler main body can refer to a specially provided air port, or can be, for example, a preset cold water inlet of the boiler main body, etc.

[0066] In the third direction, the pressure relief channel 111, the waste discharge channel 112 and the evacuation channel 114 can be in the same plane, or at least two of them are in different planes. As Figures 5 to 8 shown, taking the third direction as the gravity direction as an example, the pressure relief channel 111 and the evacuation channel 114 are at the same height, and the other port of the pressure relief channel 111 is opened at the evacuation channel 114 to form a first connection port 111a. The waste discharge channel 112 is located below the pressure relief channel 111. In this way, within the limited space of the block 110, the pressure relief channel 111, the waste discharge channel 112 and the evacuation channel 114 make full use of the space and remain independent as much as possible, which helps to be set to any suitable cross-sectional area and extension length respectively according to actual needs.

[0067] As can be seen from the above, when the whole machine is operating in the heating mode, the whole machine will not operate in the evacuation mode. At this time, the plugging member is in the partition position, so that the pressure relief channel 111 and the evacuation channel 114 are disconnected. Based on this, the pressure in the boiler main body and at the pressure relief channel 111 gradually increases, but is still less than the first preset threshold. The pressure relief valve body 120 disconnects the pressure relief channel 111 and the waste discharge channel 112 and is initially in a pressure holding state. When the temperature in the boiler main body gradually rises, the pressure also rises. When it exceeds the first preset threshold, it pushes the spool 121 in the pressure relief valve body 120 to move, conducting the pressure relief channel 111 and the waste discharge channel 112, and switching to the pressure relief state, which helps to release the excessive pressure in the boiler main body to the waste discharge channel 112.

[0068] Next, when the pressure in the pressure relief channel 111 does not reach the second preset threshold, the plugging member can be driven to the evacuation position by an external driving member; among them, the second preset threshold is not greater than the first preset threshold. It should be noted that the specific values of the first preset threshold and the second preset threshold can be adjusted according to actual needs. Among them, the first preset threshold is set to be less than or equal to the set safety pressure value in the boiler main body; the second preset threshold is set to be less than or equal to the pressure value corresponding to when the boiler main body is not operating in the heating mode, the water inlet mode, and the water outlet mode. That is, when the pressure in the boiler main body reaches the second preset threshold, it indicates that the boiler main body is currently in an idle state, and the plugging member can be driven to move to the evacuation position according to actual needs.

[0069] Among them, the specific form of the external driving member for driving the plugging member to move is not limited, and it can be, but is not limited to, a specially set driving device, such as a motor or other drivers, or a combination of a motor or other drivers and a transmission component such as a lead screw nut. Of course, according to actual needs, it can also be realized by the manual operation of the user.

[0070] At this time, in order to better supply the external driving member to drive and connect the plugging member, in a specific application, the evacuation channel 114 penetrates through the block 110 along the first direction, so as to respectively form an operation port 114b and an evacuation port 114d on the outer wall of the block 110. The operation port 114b is used for the external driving member to be inserted movably, and the evacuation port 114d is used for communicating and connecting with an external container. In this way, the operation port 114b and the evacuation port 114d can be separately arranged, so that the driving operation of the external driving member on the plugging member does not affect the evacuation effect of the evacuation channel 114.

[0071] As can be seen from the above, the pressure relief channel 111 forms a first connection port 111a on the side wall of the evacuation channel 114. Based on this, in an embodiment, the plugging member moves translationally along the first direction in the evacuation channel 114 to switch between the evacuation position and the partition position.

[0072] When the plug moves translationally along the first direction, it can move closer to and away from the first connection port 111a:

[0073] In one embodiment, at least a partial side wall of the plug forms an opening and closing part. When it moves to the partition position, the opening and closing part seals and covers the first connection port 111a; when it moves to the evacuation position, the opening and closing part of the plug keeps a gap from the first connection port 111a. The specific manifestation form of the opening and closing part can be determined according to the relative relationship between the plug and the first connection port 111a: for example, when the outer diameter of the plug is adapted to the inner diameter of the evacuation channel 114 at the first connection port 111a, so that when any side wall of the plug moves closer to the first connection port 111a, the side wall of the plug can exactly cover the first connection port 111a and be in the partition position, then any side wall of the plug directly forms the opening and closing part. When the outer diameter of the plug is smaller than the outer diameter of the evacuation channel 114, but a partial side wall bulges outward, so that when the bulging part moves closer to the first connection port 111a, it exactly blocks the first connection port 111a and is in the partition position, then the bulging part forms the opening and closing part.

[0074] Or in another embodiment, if the channel section of the evacuation channel 114 between the first connection port 111a and the operation port 114b is defined as the operation section 114a; and the channel section of the evacuation channel 114 between the first connection port 111a and the evacuation port 114d is defined as the evacuation section 114c: at least two side walls of the plug are in sealing contact with the inner wall of the evacuation channel 114 at the corresponding positions, forming the first sealing part 130a and the second sealing part 130b which are arranged at intervals; when in the evacuation position, both the first sealing part 130a and the second sealing part 130b move into the operation section 114a, so as to leave a smooth evacuation section 114c. The water body in the boiler main body can flow directly into the evacuation section 114c through the pressure relief channel 111 and the first connection port 111a, and finally be discharged outwards through the evacuation port 114d. And it also makes the operation section 114a be sealed and partitioned by the first sealing part 130a and the second sealing part 130b, so that the water body in the boiler main body cannot be discharged outwards through the operation section 114a, avoiding polluting the operation section 114a or the operation port 114b. On the contrary, when in the partition position, the first sealing part 130a moves into the operation section 114a, still making the operation section 114a be sealed and partitioned by the first sealing part 130a, so that the water body in the boiler main body cannot be discharged outwards through the operation section 114a; at the same time, it also makes the evacuation section 114c be sealed and partitioned by the second sealing part 130b, so that the water body in the boiler main body cannot be discharged outwards through the evacuation section 114c.

[0075] There are various solutions to achieve the above purpose:

[0076] In one embodiment, the plugging member includes a shaft body 131, and the shaft body 131 extends in a long shape along the extending direction of the evacuation channel 114. The shaft body 131 is not a shaft structure with a constant diameter. The outer diameter of a partial shaft segment of the shaft body 131 increases to be in sealing abutment with the inner wall of the evacuation channel 114 at the corresponding position, constituting the first sealing portion 130a or the second sealing portion 130b.

[0077] Alternatively, in one embodiment, the plugging member includes a shaft body 131, a first sealing ring 132 and a second sealing ring 133. The shaft body 131 extends in a long shape along the extending direction of the evacuation channel 114. The shaft body 131 may be a shaft structure with a constant diameter or a variable-diameter shaft structure. The first sealing ring 132 is sleeved between the outer side of the shaft body 131 and the inner wall of the evacuation channel 114 at the corresponding position to define the first sealing portion 130a; the second sealing ring 133 is sleeved between the outer side of the shaft body 131 and the inner wall of the evacuation channel 114 at the corresponding position to define the second sealing portion 130b. In this way, it helps to reduce the structural design requirements for the part of the block 110 where the evacuation channel 114 is formed and the structural design requirements for the shaft body 131. And when the shaft body 131 is made of a rigid material, by setting the first sealing ring 132 and the second sealing ring 133 to be made of an elastic material, it helps to prevent direct rigid friction between the shaft body 131 and the inner wall of the evacuation channel 114. And when the sealing effect is reduced due to wear of the first sealing portion 130a and the second sealing portion 130b, the first sealing ring 132 and the second sealing ring 133 can be disassembled and replaced.

[0078] Further, in one embodiment, the plugging member is provided with at least one third sealing portion 130c on the side where the first sealing portion 130a and the second sealing portion 130b are away from each other. That is, the third sealing portion 130c may be provided with one or at least two at the position where the first sealing portion 130a is away from the second sealing portion 130b (i.e., near the operation port 114b); and / or, the third sealing portion 130c may be provided with one or at least two at the position where the second sealing portion 130b is away from the first sealing portion 130a (i.e., near the evacuation port 114d). Similarly to the above, the third sealing portion 130c can be directly defined by the partially variable-diameter shaft body 131 or can be defined by a third sealing ring. The setting of the third sealing portion 130c, on the one hand, helps to form a multi-stage seal at the evacuation section 114c and / or at the operation section 114a, and helps to form a multi-point sliding abutment between the shaft body 131 and the evacuation channel 114, which helps the plugging member to move smoothly relative to the block 110.

[0079] Further, in one embodiment, the sealing strengths of the first sealing portion 130a, the second sealing portion 130b, and the third sealing portion 130c are set to be substantially the same, so that the structures of the first sealing portion 130a, the second sealing portion 130b, and the third sealing portion 130c are the same, and substantially equal-quality replacement can be achieved, which helps to facilitate the maintenance of the plugging member. Or in one embodiment, at least two of the sealing strengths of the first sealing portion 130a, the second sealing portion 130b, and the third sealing portion 130c are different, that is, the sealing effects of the first sealing portion 130a, the second sealing portion 130b, and the third sealing portion 130c are differentiated, which helps to meet the different sealing requirements of different drain channels 114 and the hot water system.

[0080] It should be noted that the difference in the sealing strengths of the first sealing portion 130a, the second sealing portion 130b, and the third sealing portion 130c can be achieved through, for example, the difference in the specifications of the first sealing ring 132, the second sealing ring 133, and the third sealing ring. The specifications include but are not limited to dimensions, materials, shapes, etc.

[0081] In addition, please refer to Figures 7 to 8 , in one embodiment, at least one stop protrusion 114e is provided on the inner wall of the drain channel 114, and a mating protrusion 131b is correspondingly provided on the outer wall of the plugging member. The stop protrusion 114e and the mating protrusion 131b are movably matched to limit the movement of the plugging member within a preset stroke range. Specifically, when the stop protrusion 114e and the mating protrusion 131b are provided as a set, the movement stroke of the plugging member can be limited and stopped on one side; when the stop protrusion 114e and the mating protrusion 131b are provided as two spaced sets, the movement strokes of both sides of the plugging member can be limited and stopped. Among them, the one-sided limit stop can be the limit stop on the side where the operation port 114b is located to prevent the plugging member from protruding outwards from the operation port 114b; it can also be the limit stop on the side where the drain port 114d is located to prevent the plugging member from protruding outwards from the drain port 114d.

[0082] The positions of the stop protrusion 114e and the corresponding mating protrusion 131b can be set according to actual needs: when the limit stop between the stop protrusion 114e and the corresponding mating protrusion 131b is used to prevent the plugging member from protruding outwards from the drain channel 114, the two can be set at a position closer to the operation port 114b or closer to the drain port 114d. When the limit stop between the stop protrusion 114e and the corresponding mating protrusion 131b is used to define a specified position point, for example, when the stop protrusion 114e and the corresponding mating protrusion 131b are in contact, the plugging member is exactly in the blocking position or exactly in the draining position.

[0083] There is no limitation on the formation manner of the stop projection 114e and the corresponding mating projection 131b. In one embodiment, for example, when the shaft body 131 is a stepped shaft and has at least two stepped shaft segments 131a with different outer diameters, the mating projection 131b is directly defined at the position where the outer diameters of two adjacent stepped shaft segments 131a change. Similarly, the evacuation channel 114 can be a stepped hole with at least two stepped hole segments with different inner diameters, and the stop projection 114e is directly defined at the position where the inner diameters of two adjacent stepped hole segments change.

[0084] In the above embodiment, the evacuation channel 114 is connected to the boiler main body through the pressure relief channel 111. On the one hand, it helps to reduce the number of opening structures on the boiler main body and the number of butt joints between the block 110 and the boiler main body, thus contributing to the simplification of the structure and operation; on the other hand, it helps to achieve the safety pressure relief of the boiler main body / pressure relief channel 111 when the function of the pressure relief valve body 120 to automatically adjust the pressure of the boiler main body / pressure relief channel 111 fails, such as when the pressure relief valve body 120 fails or the waste discharge channel 112 is blocked. Or when the pressure relief efficiency of the pressure relief valve body 120 is low, the plug can also be operated to move to the evacuation position, and by virtue of the larger inner diameter of the evacuation channel 114, the flow rate of the air flow can be increased, thereby helping to assist the pressure relief valve body 120 to perform more efficient pressure relief.

[0085] In addition, in one embodiment, the opening on the boiler main body connected to the pressure relief channel 111 can be opened at the bottom of the boiler main body and arranged downward, which helps to more efficiently discharge the water body in the boiler main body to the evacuation channel 114 by means of the gravity effect.

[0086] Furthermore, a certain recess can be formed by concaveing the inner bottom wall of the boiler main body, and the opening connected to the pressure relief channel 111 can be arranged on the side wall of the recess and form a certain height difference from the bottom wall of the recess. In this way, a certain amount of solid impurities can be settled and accommodated by means of the recess, avoiding the solid impurities generated in the boiler main body from flowing through the pressure relief channel 111, the waste discharge channel 112 and the evacuation channel 114, resulting in the blockage of the pressure relief channel 111, the waste discharge channel 112 and / or the evacuation channel 114.

[0087] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
