In addition, the pressure relief valve body helps to ensure the normal operation of the functions of the hot water boiler and the pipeline connection module. When the internal pressure of the hot water boiler is too high and transmitted to the pressure relief channel, the pressure relief valve body can conduct the connection channel by changing the position of the movable valve core, so that the pressure relief channel is connected and communicated with the waste discharge channel, which helps to reduce the internal pressure of the hot water boiler, and the safety of the pressure relief process and the service life of the pressure relief channel can be improved by virtue of the structural strength and other characteristics of the block. One end port of the connection channel penetrates through the outer wall of the block, which helps to improve the disassembly and assembly convenience of the pressure relief valve body at the block, so that the functional maintenance operation of the pressure relief valve body is more simple and efficient, and ultimately helps to improve the use reliability of the whole machine.

[0049] Please refer to Figures 1 to 8 , the present utility model provides a pipeline connection module 100. The pipeline connection module 100 is mainly applied in a hot water system, and the hot water system can be specifically applied in a beverage processing device.

[0050] It can be understood that the pipeline connection 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, grinding modules, brewing modules, milk supply modules, etc.

[0051] Specifically, in actual applications:

[0052] 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 connection 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.

[0053] 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.

[0054] The hot water system also has a water outlet mode. In this mode, the boiler main body can be connected to an external functional module through, for example, a preset channel structure in the pipeline connection module 100, so as to be able to provide 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 provide hot water to, for example, a beverage outlet outside the casing.

[0055] The hot water system also has a pressure relief mode. When the continuous operation of the heating device causes the pressure in the boiler main body to exceed the preset threshold, a certain high pressure can be released to the outside through, for example, the pipeline connection module 100, so as to ensure that the pressure in the boiler main body is stable within a suitable range and ensure the safe operation of the hot water system.

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

[0057] Please combine Figures 2 to 8 , the pipeline connection module 100 in the present utility model includes a block body 110 and a pressure relief valve body 120. Among them, the block body 110 is respectively provided with a pressure relief channel 111, a waste discharge channel 112 and a connection channel 113. One port of the pressure relief channel 111 penetrates through the outer wall of the block body 110 and is used for communicating and connecting with the hot water boiler 200. At least one port of the waste discharge channel 112 penetrates through the outer wall of the block body 110. One port of the connection channel 113 communicates and connects the pressure relief channel 111 and the waste discharge channel 112. The other port of the connection channel 113 penetrates through the outer wall of the block body 110; the pressure relief valve body 120 is detachably installed in the connection channel 113. The pressure relief valve body 120 includes a valve core 121 that can be movably arranged. When the pressure in the pressure relief channel 111 does not reach the preset threshold, the valve core 121 moves to block the connection channel 113; when the pressure in the pressure relief channel 111 reaches the preset threshold, the valve core 121 moves to conduct the connection channel 113.

[0058] In the technical solution provided by the present utility model, a pressure relief channel 111, a waste discharge channel 112, and a connection channel 113 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 facilitating the simplification of the overall structural design and disassembly and assembly operations. On the other hand, the installation positions of each channel structure such as the pressure relief channel 111, the waste discharge channel 112, and the connection channel 113 are fixed, which helps to avoid adverse situations such as mutual separation or force-induced deformation during use. In addition, the pressure relief valve body 120 helps to ensure the normal operation of the functions of the hot water boiler 200 and the pipeline connection module 100. When the hot water system is in the pressure relief mode, that is, when the internal pressure of the hot water boiler 200 is too high and transmitted to the pressure relief channel 111, the pressure relief valve body 120 can conduct the connection channel 113 by adjusting the position of the movable valve core 121, so that the pressure relief channel 111 is connected to the waste discharge channel 112, which helps to reduce the internal pressure of the hot water boiler 200. Moreover, by leveraging the structural strength and other characteristics of the block 110, the safety of the pressure relief process and the service life of the pressure relief channel 111 can be improved. One end of the connection channel 113 penetrates the outer wall of the block 110, which helps to improve the convenience of disassembly and assembly of the pressure relief valve body 120 at the block 110, thereby making the functional maintenance operation of the pressure relief valve body 120 simpler and more efficient, and ultimately contributing to the improvement of the reliability of the entire machine.

[0059] In this design, the block 110 generally refers to a three-dimensional structure with a certain length, width, and height. For the sake of easy understanding, in the following embodiments, the block 110 is defined to have a first direction, a second direction, and a third direction that are pairwise cross-set. Among them, when the first direction, the second direction, and the third direction are pairwise cross at 90°, 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 or a polyhedral prism shape. 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 casing 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, sufficient space is reserved inside it for opening each channel structure. In this embodiment, at least a pressure relief channel 111, a waste discharge channel 112, and a connection channel 113 are opened inside the block 110.

[0062] Among them, the waste discharge channel 112 can be arranged to extend in the first direction. At least one port of the waste discharge channel 112 penetrates through 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 casing of the beverage processing device, or a waste residue box fixedly arranged inside the casing, etc.

[0063] The pressure relief channel 111 is arranged to extend in the second direction. One port of the pressure relief channel 111 penetrates through the outer wall of the block 110 to form a pressure relief port that is connected and communicated with an opening of the boiler main body. It should be noted that the opening of the above-mentioned 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.

[0064] In the third direction, the pressure relief channel 111 and the waste discharge channel 112 can be in the same plane. Or as Figures 3 to 4 shown, the pressure relief channel 111 and the waste discharge channel 112 are in different planes in the third direction, so that in the limited space of the block 110, the pressure relief channel 111 and the waste discharge channel 112 can be kept as independent as possible, which helps to be respectively set to any suitable cross-sectional area and extension length according to actual needs.

[0065] The connection channel 113 can be directly arranged at the intersection of the waste discharge channel 112 and the pressure relief channel 111, or be arranged adjacent to the intersection of the waste discharge channel 112 and the pressure relief channel 111. The connection channel 113 is arranged to extend in the third direction and is arranged such that one port penetrates through the outer wall of the block 110. In this way, at least a part of the connection channel 113 can be exposed on the outer wall of the block 110, making the disassembly and assembly of the pressure relief valve body 120 at the connection channel 113 more convenient.

[0066] To achieve the above functions, please refer to Figures 4 to 6 In one embodiment, the connection channel 113 can specifically include a groove 113a, a first channel section 113b, and a second channel section 113c. Among them, the groove 113a is opened on one outer wall of the block 110 in the third direction; the first channel section 113b is connected and communicated with the bottom wall of the groove 113a of the pressure relief channel 111; the second channel section 113c is independently arranged from the first channel section 113b and is connected and communicated with the bottom wall of the groove 113a of the waste discharge channel 112. The first channel section 113b and the second channel section 113c can both extend along the third direction and are arranged at intervals in the first direction or the second direction; the groove 113a is connected and communicated with the ports at the same end of the first channel section 113b and the second channel section 113c, so that the first channel section 113b can form a first port at the bottom wall of the groove 113a, and the second channel section 113c can form a second port at the bottom wall of the groove 113a.

[0067] The valve core 121 in the pressure relief valve body 120 can act on at least the first port or the second port, so that the first port or the second port is opened or covered.

[0068] Specifically, please refer to Figures 4 to 8 , in an embodiment, the pressure relief valve body 120 further includes a housing 122 and an elastic member 123. Among them, the housing 122 covers the notch of the groove 113a and covers at least the ports of the first channel section 113b and the second channel section 113c. The valve core 121 is movably arranged in the housing 122; the elastic member 123 is connected between the inner wall of the housing 122 and the valve core 121; among them, when the pressure in the first channel section 113b does not reach the preset threshold value, the valve core 121 is pushed by the elastic member 123 to cover the port of the first channel section 113b; when the pressure in the first channel section 113b reaches the preset threshold value, the valve core 121 is pushed away and the port of the first channel section 113b is opened.

[0069] It can be understood that the housing 122 extends along the third direction and is presented as a single-ended open cylinder. When the size of the open end of the housing 122 is large enough, it can be directly covered outside the groove 113a and cover the notch of the groove 113a.

[0070] Or when the size of the open end of the housing 122 is small, at least the open end of the housing 122 can be inserted into the groove 113a. At this time, the side wall of the insertion section of the housing 122 is in sealing contact with the side wall of the groove 113a. The sealing contact mode between the two can be directly realized by interference fit in size, or can be realized by structures such as sealing ribs sleeved on the outside of the housing 122 or protruding on the inner side wall of the groove 113a. The remaining part of the housing 122 extends out of the groove 113a and a support step 122a is convexly provided on the side wall. The step surface of the support step 122a facing the block 110 can directly support on the outer wall of the block 110.

[0071] The housing 122 can be detachably connected to the block 110 by, for example, screwing. Or further, in an embodiment, the pressure relief valve body 120 further includes an annular pressing plate 126 disposed around the outer periphery of the housing 122. The annular pressing plate 126 is partially connected and fixed to the outer wall of the block 110, and the remaining part of the annular pressing plate 126 is at least partially pressed on the surface of the end of the support step 122a facing away from the groove 113a. The annular pressing plate 126 and the block 110 are detachably connected by screwing, buckling, pasting, magnetic attraction and other methods. The annular pressing plate 126 can be pressed on the step surface of the support step 122a facing away from the cover body, so as to be able to jointly clamp and limit the support step 122a with the outer wall of the block 110, and then be able to fix the housing 122 on the block 110.

[0072] When the housing 122 is fixedly connected to the block 110, the housing 122 can at least block the first port and the second port, preventing the first channel section 113b and the second channel section 113c from directly communicating with the environment outside the block 110. The valve core 121 can be specifically arranged corresponding to the first port or the second port. However, in order to better sense and receive the pressure change in the pressure relief channel 111, the valve core 121 can be arranged corresponding to the first port and is displaceable in the directions approaching and departing from the first port, so as to be able to move to cover the first port and move to open the first port respectively. The elastic member 123 is, for example, a spring member, a metal shrapnel, a rubber block, etc. The elastic member 123 can apply at least a unidirectional force to the valve core 121 through its own elastic deformation.

[0073] Specifically, when the pressure in the pressure relief channel 111 / the first channel section 113b is less than the preset threshold, the force applied by the elastic member 123 to the valve core 121 is relatively large, and the valve core 121 can be pressed against the state of covering the first port; conversely, when the pressure in the pressure relief channel 111 / the first channel section 113b is greater than or equal to the preset threshold, the force applied by the elastic member 123 to the valve core 121 is less than the force applied by the pressure in the first channel section 113b to the valve core 121, and the valve core 121 is pushed away from the first port by the pressure, so that the first port is opened. At this time, the first port and the second port communicate in the groove 113a, and the airflow in the pressure relief channel 111 can flow through the first channel section 113b, the groove 113a and the second channel section 113c in sequence, and finally flow to the waste discharge channel 112.

[0074] Further, in an embodiment, the pressure relief valve body 120 further includes a sealing cylinder member 124 and a sealing plate member 125. Among them, the sealing cylinder member 124 is inserted and connected to the first channel section 113b, and at least partially extends from the inside of the first channel section 113b to the inside of the groove 113a; the sealing plate member 125 is arranged at one end of the valve core 121 facing the bottom wall of the groove 113a, and abuts against the mouth part of the sealing cylinder member 124 when the pressure in the first channel section 113b does not reach the preset threshold; and is pushed and separated from the mouth part of the sealing cylinder member 124 when the pressure in the first channel section 113b reaches the preset threshold.

[0075] The outer diameter of the cylinder section of the sealing cylinder member 124 inserted into the first channel section 113b can be set to be adapted to the inner diameter of the first channel section 113b at the corresponding position, or slightly larger than the inner diameter of the first channel section 113b at the corresponding position, to ensure a sealed connection between the sealing cylinder member 124 and the first channel section 113b.

[0076] In a further solution, the ventilation cross-sectional area of the sealing cylinder member 124 is equivalent to that of the second channel section 113c. That is, the gas flow rate flowing through the sealing cylinder member 124 via the first channel section 113b is substantially the same as the gas flow rate flowing through the second channel section 113c.

[0077] Next, in a specific application, the part of the sealing cylinder member 124 extending into the groove 113a includes an annular platform stage 124a. Among them, the annular platform stage 124a laterally extends to completely cover the port of the first channel section 113b and is clamped between the bottom wall of the groove 113a and the end wall of the valve core 121. The setting of the annular platform stage 124a can, on the one hand, further cover the possible installation gap between the sealing cylinder member 124 and the first channel section 113b; on the other hand, it can increase the connection tightness between the sealing cylinder member 124 and the valve core 121 through the annular platform stage 124a.

[0078] Furthermore, in an embodiment, the part of the sealing cylinder member 124 extending into the groove 113a further includes a boss section 124b. The boss section 124b protrudes from one end of the annular platform stage 124a facing away from the bottom wall of the groove 113a. The boss section 124b can be annularly surrounded along the entire circumference of the first channel section 113b, or can extend along a partial outer circumference of the first channel section 113b in a convex shape or a rib shape. Since one of the boss section 124b and the sealing plate member 125 is made of a rigid material and the other is made of an elastic material. When the pressure in the pressure relief channel 111 / the first channel section 113b does not reach the preset threshold, the sealing plate member 125 and the valve core 121 are pressed by the elastic member 123 and closely fit with the boss section 124b, and the tightness at the connection between the two is increased under the appropriate deformation of the elastic material, and the shape of the joint between the two is more adaptable without excessive wear.

[0079] The boss section 124b can be vertical along its protruding direction; or can be inclined or arc-shaped along its protruding direction, that is, the outer diameter of the boss section 124b is set to gradually decrease along its protruding direction. In this way, it helps to further enhance the sealing connection effect between the sealing plate member 125 and the sealing cylinder member 124.

[0080] Of course, the protruding height of the boss section 124b, the inclination angle of the boss section 124b, etc. need to be set within an appropriate range, and the end surface of the boss section 124b connected to the sealing plate member 125 can be set as a flat surface to avoid being in contact with the sealing plate member 125 and causing the part made of elastic material to be easily damaged due to stress concentration.

[0081] The plate surface of the sealing plate member 125 can be specifically set to extend to cover the entire end surface of the valve core 121 facing the bottom wall of the groove 113a, or at least be able to cover the barrel opening of the sealing barrel member 124. In specific applications, the plate surface of the sealing plate member 125 is set to extend beyond the boss section 124b and at least partially cover the step surface of the annular table stage 124a of the sealing barrel member 124.

[0082] When the sealing plate member 125 is made of the same material as the valve core 121, the sealing plate member 125 and the valve core 121 can be integrally formed. Or whether the sealing plate member 125 and the valve core 121 are made of the same material or not, the sealing plate member 125 and the valve core 121 can be obtained by detachably or non-detachably connecting them after being separately formed.

[0083] Specifically, when the sealing plate member 125 is made of an elastic material, an installation groove 121a is recessed in one end wall of the valve core 121 facing the bottom wall of the groove 113a. The sealing plate member 125 is detachably installed in the installation groove 121a. The sealing plate member 125 is provided with a through hole 121b, and the through hole 121b penetrates through the bottom wall of the installation groove 121a. The through hole 121b can also be set to penetrate through the valve core 121 along the third direction. The setting of the through hole 121b can ensure that the installation of the sealing plate member 125 in the installation groove 121a is more fitting and stable when the sealing plate member 125 is installed into the installation groove 121a.

[0084] Furthermore, based on any of the above embodiments, at least the part of the block 110 where the pressure relief channel 111 is formed is made of a heat-conducting material. Even further, it can be that the parts where the pressure relief channel 111, the connection channel 113, and the waste discharge channel 112 are formed are made of a heat-conducting material. Specifically, for example, the block 110 can be made of a metal material, which not only has sufficient structural strength but also has sufficient heat-conducting effect due to the metal material, so that when the hot gas in the boiler main body passes through the pressure relief channel 111, the connection channel 113, and the waste discharge channel 112, it can be well cooled by heat dissipation, avoiding damage to the block 110 by the hot gas or burning the user when the hot gas is discharged outward.

[0085] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. 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.
