Description

Technical Field

[0001] This utility model relates to the technical field of pipeline connection structure for beverage equipment, and specifically to a separate pipeline connection structure for a beverage machine. Background Technology

[0002] In practical applications of beverage preparation equipment such as beverage machines, coffee machines, and milk tea machines, it is necessary to stably transport the juice, syrup, and other liquids stored in the freezer to the machine head above the freezer via pipelines to complete the beverage preparation process. Currently, the industry commonly uses a continuous flexible hose connection, where the hose extends directly from inside the freezer through pre-drilled holes in the cabinet to the machine head. This traditional structure has revealed numerous prominent problems during long-term use, seriously affecting equipment maintenance efficiency and economic viability. The specific problems are as follows: 1. Because the flexible hose needs to cross both the cold zone inside the freezer and the ambient temperature zone outside, the temperature difference causes bacteria and scale to easily grow on the inner wall of the hose section in the ambient temperature zone. This results in a significantly higher rate of aging and damage compared to the hose section in the constant-temperature cold zone, requiring more frequent replacements. However, traditional integrated hose designs require the entire hose to be disassembled and replaced when only a partially damaged section needs replacement. This not only increases the complexity of maintenance but also leads to the unnecessary discarding of hoses in the undamaged cold zone, significantly increasing operating costs.

[0003] 2. Due to the limited operating space caused by the internal structure of the equipment, the process of pulling out and re-inserting the hose through the freezer's holes is time-consuming and laborious, severely reducing installation and maintenance efficiency. Furthermore, the existing equipment's pre-drilled holes are mostly simple cable routing holes without dedicated pipe positioning and protection interfaces. The hose is prone to wear and breakage due to long-term friction and compression at these holes, and the poor sealing between the holes and the hose can lead to cold loss or the intrusion of external impurities. In addition, the simple cable routing hole design cannot achieve independent zoned management of the piping, further exacerbating the difficulty of operation and maintenance.

[0004] In summary, the existing through-hole hose connection structure has problems such as inconvenient maintenance, serious material waste, low installation and replacement efficiency, and insufficient sealing and stability. Utility Model Content

[0005] The purpose of this invention is to provide a separate connection structure for the piping of a beverage machine to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A detachable connection structure for a beverage machine's piping includes a fixed base for installation in a pre-drilled hole in the main body of a freezer, and at least one connecting pipe detachably connected to the fixed base. Both ends of the connecting pipe have pagoda-shaped ends, with one pagoda-shaped end located inside the freezer body and used to connect to a lower hose, and the other pagoda-shaped end located outside the freezer body and used to connect to an upper hose. The upper and lower hoses are connected to their respective pagoda-shaped ends via their flexible structures, forming a connection between the hoses in different areas. The outer wall of the connecting pipe has a wrench-compatible edge fastening part, which is used to tighten the connecting pipe by applying force with a standard wrench during the threaded insertion of the connecting pipe into the fixed base, thereby achieving stable axial positioning of the connecting pipe. One end of the edge fastening part is provided with a limiting flange for abutting against the fixed base, the limiting flange being connected to the connecting pipe, and at least one through-hole area for threading and pipe insertion is provided on the surface of the fixed base.

[0007] Preferably, the surface of the fixed base is provided with multiple threaded channels, and the connecting pipe is threaded into the corresponding threaded channels.

[0008] Preferably, the outer wall of the connecting pipe is provided with external threads, and the connecting pipe is detachably connected to the threaded channel of the fixed base through the external threads, and the external threads are located on the side of the limiting flange away from the edge fastening part.

[0009] Preferably, the edge fastening part is a hexagonal fastening part, and the opposite side dimensions of the hexagon are designed according to the standard wrench specifications, so that it can be directly used with common tools, making it convenient for installers to apply torque for fastening in confined spaces.

[0010] Preferably, the wiring and conduit area is circular or rectangular, used to provide space for wires or other conduits to pass through, so that different types of conduits can be centrally laid out in the same structure.

[0011] Preferably, the two ends of the connecting pipe are integrally formed with the limiting flange and the edge fastening part to improve the structural strength and prevent loosening or leakage problems that may occur with the split connection.

[0012] Preferably, the connecting pipe is manufactured using a turning process.

[0013] Preferably, the fixing base is made of metal.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: This utility model provides a separate connection structure for the piping of a beverage machine. By setting a fixed base and a detachable threaded double-ended pagoda connecting pipe between the freezer body and the beverage machine, the cold section and the normal temperature section of the hose can be arranged and replaced separately. This solves the problems of maintenance difficulties, material waste and inconvenient replacement caused by the traditional whole hose being laid across areas. This utility model is suitable for beverage machines, coffee machines, milk tea machines and other beverage equipment that require cross-area piping arrangements.

[0015] This utility model provides a separate connection structure for the pipeline of a beverage machine. Through the cooperation of the external thread on the connecting pipe, the limiting flange and the hexagonal fastening part, the connecting pipe can achieve stable assembly and positioning in the fixed base. At the same time, it is convenient for workers to use a wrench to apply force for tightening, thereby ensuring the sealing of the connection and the reliability of the installation.

[0018] The present invention will be further described in detail below with reference to embodiments: like Figures 1-3 As shown, this utility model provides a detachable connection structure for a beverage machine's piping, including a fixed base 1 for installation in a pre-drilled hole in the freezer body 7 and at least one connecting pipe 2 detachably connected to the fixed base 1. Both ends of the connecting pipe 2 have pagoda-shaped ends, and the middle part has a limiting flange 3 with a protruding outer diameter. The pagoda-shaped end of one end of the connecting pipe 2 is located inside the freezer body 7 and is used to connect to the lower hose, while the pagoda-shaped end of the other end of the connecting pipe 2 is located outside the freezer body 7 and is used to connect to the upper hose. The outer wall of the connecting pipe 2 has a wrench-compatible edge for tightening. The edge fastening part 6 is used to tighten the connecting pipe 2 by applying force with a standard wrench during the process of screwing the connecting pipe 2 into the fixed base 1, so as to achieve stable positioning of the connecting pipe 2 in the axial direction. One end of the edge fastening part 6 is provided with a limiting flange 3 for abutting against the fixed base 1. The limiting flange 3 is connected to the connecting pipe 2, and the connecting pipe 2 is axially positioned in the fixed base 1 by the limiting flange 3, so that the hoses at both ends maintain a corresponding distance relationship when connected, which facilitates the wiring of the whole machine structure; and at least one wire and pipe passage area 5 is opened through the surface of the fixed base 1.

[0019] Specifically, the upper and lower hoses are respectively fitted with their corresponding pagoda connectors for quick assembly at both ends of the threaded double-ended pagoda connector 2, forming a reliable connection. Furthermore, the upper and lower hoses can be independently disassembled, allowing the hoses located in the ambient temperature zone above the freezer body 7 to be replaced separately without disassembling the internal hoses of the freezer, thereby reducing material waste and significantly improving maintenance efficiency.

[0020] Combination Figure 1 and Figure 2 As shown, further, the surface of the fixed base 1 is provided with multiple threaded channels (not shown in the figure), the connecting pipe 2 is threaded into the corresponding threaded channel, the outer wall of the connecting pipe 2 is provided with external thread 4, the connecting pipe 2 is detachably connected to the threaded channel of the fixed base 1 through the external thread 4, and the external thread 4 is located on the side of the limiting flange 3 away from the edge fastening part 6.

[0021] Furthermore, the connecting pipe 2 has an axially continuous structure and can be completely disassembled from the fixed base 1, facilitating independent replacement and cleaning of the hose. A limiting flange 3 is formed in the center of the connecting pipe 2, and below the limiting flange 3 is an external thread section for screwing into the fixed base 1. Both ends have pagoda head structures for connecting with the upper and lower hoses respectively.

[0022] Furthermore, the edge fastening part 6 is a hexagonal fastening part, which is used to cooperate with a wrench to apply torque. The opposite side dimensions of the hexagon are designed according to the standard wrench specifications, so that it can be directly used with common tools, making it convenient for installers to apply torque for fastening in confined spaces.

[0023] Furthermore, the two ends of the connecting pipe 2 are integrally formed with the limiting flange 3 and the edge fastening part 6, and the integrally formed connecting pipe 2 is made by turning forming process. Through this design, the structural strength of the connecting pipe 2 can be improved to prevent loosening or leakage problems that may occur in the split connecting components.

[0024] Combination Figure 1 As shown in the figure, in one embodiment, the wire and pipe threading area 5 is rectangular.

[0025] In another embodiment, the wiring and conduit area 5 is circular.

[0026] Specifically, the dimensions of the wiring and conduit area 5 are pre-planned based on the outer diameter of the wires and conduits. It can be rectangular or circular, ensuring reasonable wiring space without creating unnecessary gaps, while reducing the number of openings in the freezer body 7 and improving the overall structural integration. It is worth noting that the wiring and conduit area 5 includes, but is not limited to, rectangular or circular shapes, and can also be elliptical, rhomboid, etc.

[0027] Furthermore, the fixed base 1 is made of metal or high-strength engineering materials to improve the wear resistance and structural stability of the threaded channel, thereby enhancing the reliability of the connecting pipe 2 during high-frequency assembly and disassembly.

[0028] The working principle of this beverage machine's detachable pipeline connection structure will be explained in detail below.

[0029] like Figures 1-3 As shown, the fixed base 1 forms a transition interface at the installation position of the freezer body 7, allowing the lower flexible hose inside the freezer body 7 to be connected to the upper flexible hose outside the freezer body 7 via a threaded double-ended pagoda connector 2, thus forming a separate pipeline arrangement for easy maintenance and installation. At the same time, the wiring and conduit area 5 of the fixed base 1 allows wires or other functional pipelines to pass through this position of the freezer body 7, ensuring reasonable wiring space without creating unnecessary gaps, reducing the number of openings in the freezer body 7 and improving the integration of the overall structure.
