[0040] Another core of the present utility model is to disclose a beverage machine including the above multi-pipeline docking device.
[0041] Hereinafter, embodiments will be described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the utility model described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the utility model described in the claims. It should be noted that for the convenience of description, only the parts related to the relevant utility model are shown in the drawings. Without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.
[0042] Combined with Figures 1-10 , the multi-pipeline docking device disclosed by the present utility model includes a first docking seat 100, a gasket 200, and a second docking seat 300. The gasket 200 is disposed between the first docking seat 100 and the second docking seat 300 and is integrally formed with one of the first docking seat 100 and the second docking seat 300. The first docking seat 100 has a plurality of first pipelines, and the second docking seat 300 has a plurality of second pipelines. The first docking seat 100 is connected to the second docking seat 300, and each first pipeline and the second pipeline are correspondingly connected and sealed by the gasket 200 to form a plurality of series pipelines, and the series pipelines are used to realize the connection between the under-counter refrigeration equipment 400 and the product outlet assembly on the countertop.
[0043] During assembly, the first docking seat 100 can be directly installed on the integrated structure of the second docking seat 300 and the gasket 200, or the second docking seat 300 can be installed on the integrated structure composed of the first docking seat 100 and the gasket 200, and the first pipeline and the second pipeline are connected. Then, the first docking seat 100 and the second docking seat 300 are connected by screws or bolts. Finally, the assembled multi-pipeline docking device is fixed on the mounting hole 410 on the top wall of the refrigeration equipment 400, and then the refrigeration equipment 400 and the multi-pipeline docking device can be jointly moved to the countertop. After the product outlet pipelines of the product outlet assembly above the countertop are correspondingly connected to each series pipeline of the multi-pipeline docking device one by one, the rapid assembly of the beverage machine at the countertop is completed; during disassembly, first disconnect each product outlet pipeline from the multi-pipeline docking device, then move the refrigeration equipment 400 and the multi-pipeline docking device out of the countertop, and finally disassemble the refrigeration equipment 400 and the multi-pipeline docking device.
[0044] Compared with the prior art, the multi-pipeline docking device disclosed by the present utility model can achieve sealed connection between the under-counter refrigeration equipment 400 and the product outlet assembly on the countertop. Moreover, the multi-pipeline docking device sets the gasket 200 and one of the first docking seat 100 and the second docking seat 300 as an integral structure, reducing the assembly steps of the multi-pipeline docking device and improving the assembly efficiency of the beverage machine.
[0045] Specifically, the gasket 200 and the first docking seat 100 or the second docking seat 300 can be integrally formed by means of overmolding.
[0046] To ensure the accuracy of positioning, a positioning step is provided on one of the first docking seat 100 or the second docking seat 300, and the end of the other can abut against the positioning step. For example, in combination with Figure 6 , this figure shows a solution in which a positioning step is provided on the first docking seat 100, and the second docking seat 300 is used to be inserted into the first docking seat 100 and abut against the positioning step for positioning.
[0047] In combination with Figure 7 , in an embodiment, a plurality of sealed pipelines are provided on the gasket 200, and each of the sealed pipelines is in one-to-one correspondence and communication with the series pipelines. Specifically, each first pipeline is in fit with the inner wall of the first end of the sealed pipeline, and the outer wall of the second end of the sealed pipeline is in fit with the inner wall of the second pipeline (axially, the first pipeline and the second pipeline may partially overlap), that is, the outer diameter of the first pipeline is smaller than the inner diameter of the second pipeline, and the sealed pipeline is in interference fit with both the first pipeline and the second pipeline to avoid liquid leakage.
[0048] Among them, in order to ensure the accuracy of the relative positions among the first pipeline, the second pipeline and the sealed pipeline, in combination with Figure 7 , a positioning step for abutting against the end face of the first end of the sealed pipeline is provided on the outer wall of the first pipeline, and a positioning step for abutting against the end face of the second end of the sealed pipeline is provided on the inner wall of the second pipeline.
[0049] In combination with Figures 3-5, usually the first pipeline is symmetrically arranged around the center on the first docking seat 100, and the second pipeline is symmetrically arranged around the center on the second docking seat 300. In order to avoid contamination between different beverages caused by the assembly misalignment of the first docking seat 100 and the second docking seat 300 during disassembly and assembly, a first docking insertion tube 110 is eccentrically arranged on the first docking seat 100, and a second docking insertion tube 310 is arranged on the second docking seat 300. The position of the second docking insertion tube 310 corresponds to that of the first docking insertion tube 110, that is, the second docking insertion tube 310 is eccentrically arranged relative to the second docking seat 300, and the second docking insertion tube 310 is inserted and connected with the first docking insertion tube 110. During assembly, the correct assembly of the first docking seat 100 and the second docking seat 300 can be ensured by the alignment of the first docking insertion tube 110 and the second docking insertion tube 310, and combined with Figure 6 , the first docking insertion tube 110 and the second docking insertion tube 310 are communicated to form a series connection channel, and this series connection channel can also be used for the communication between the under-counter refrigeration device 400 and the on-counter product output component.
[0050] In order to realize the positioning of the first docking insertion tube 110 and the second docking insertion tube 310, a positioning step is arranged on one of the first docking insertion tube 110 and the second docking insertion tube 310, and the end of the other is abutted and connected with the positioning step.
[0051] Further, an annular first limit slot is formed on the outer wall of one of the first docking insertion tube 110 and the second docking insertion tube 310, and a second limit slot is formed on the other. A limit insertion piece 320 is slidably arranged on the second limit slot. After the first docking insertion tube 110 and the second docking insertion tube 310 are inserted and assembled in place, the positions of the first limit slot and the second limit slot correspond. By pushing the limit insertion piece 320 to slide in the second limit slot, the clamping connection between the limit insertion piece 320 and the first limit slot can be realized. At this time, the first docking insertion tube 110 or the second docking insertion tube 310 provided with the first limit slot cannot move relative to the first docking insertion tube 110 or the second docking insertion tube 310 provided with the second limit slot.
[0052] Combined with Figure 6 and Figure 2 , it shows a technical solution in which the first docking insertion tube 110 is inserted into the second docking insertion tube 310, a first limit slot is formed on the first docking insertion tube 110, and a second limit slot is formed on the second docking insertion tube 310, and by sliding the limit insertion piece 320, the first docking insertion tube 110 can be limited in the second docking insertion tube 310.
[0053] Specifically, combined with Figure 2, the limit insertion piece 320 includes a plugging part and an operating part. The plugging part and the operating part are connected. The plugging part is slidably arranged in the second limit slot and is provided with a clamping groove that is clamped with the first limit slot. The operating part is used for manual operation by a person (pushing and pulling actions).
[0054] Among them, the plugging part and the operating part are perpendicular, so that the limit insertion piece 320 presents an L shape.
[0055] Combined with Figure 2 , in order to realize the guiding of the sliding action of the limit insertion piece 320 in the second limit slot, a guiding groove is opened at one end of the plugging part away from the operating part. A guiding post 321 is arranged in the second limit slot. The guiding post 321 is arranged in the guiding groove. As the plugging part slides in the second limit slot, the guiding post 321 slides in the guiding groove. That is, with the cooperation of the guiding post 321 and the guiding groove, the stability of the sliding action of the limit insertion piece 320 is ensured.
[0056] In order to prevent the limit insertion piece 320 from coming out of the second limit slot, a limiting part can be arranged on the plugging part to limit the extreme position of the plugging part sliding in the second limit slot. Specifically, the operating part can be used as the limiting part to abut against the outer wall of the first side of the second docking cannula 310 to limit an extreme position of the plugging part sliding. A stop block is detachably (convenient for assembly) arranged at one end of the plugging part away from the operating part. The stop block is used as the limiting part to abut against the outer wall of the second side of the second docking cannula 310 to limit another extreme position of the plugging part sliding.
[0057] The above-mentioned first docking cannula 110 and the first docking seat 100 are detachably connected, and the second docking cannula 310 and the second docking seat 300 are detachably connected. Specifically, the detachable connection can be realized by using bolts or screws.
[0058] In order to facilitate the installation of the first docking cannula 110 and the second docking cannula 310, a first cannula seat for installing the first docking cannula 110 can be arranged on the first docking seat 100, and a second cannula seat for installing the second docking cannula 310 can be arranged on the second docking seat 300. Between the first docking cannula 110 and the first cannula seat, and between the second docking cannula 310 and the second cannula seat, they can all be tightened by nuts.
[0059] Furthermore, in order to prevent leakage of the first docking cannula 110 and the second docking cannula 310, a sealing member can be arranged between the first docking cannula 110 and the second docking cannula 310. The sealing member can be a gasket or an O-ring.
[0060] The preparation materials of the first docking seat 100 and the second docking seat 300 can be the same or different. For example, they can be food-grade polyphenylene sulfide (PPS). The gasket 200 can be prepared from food-grade thermoplastic elastomer (TPE) soft rubber material.
[0061] The beverage machine disclosed by the present utility model includes a refrigeration device 400 for being arranged under the tabletop, a product output assembly for being arranged on the tabletop, and the multi-pipeline docking device described above. The multi-pipeline docking device is used to be arranged on the top wall of the refrigeration device 400, that is, the multi-pipeline docking device is also arranged under the tabletop, and the first pipeline of the multi-pipeline docking device is in one-to-one correspondence and communication with each product output pipeline of the product output assembly. A plurality of material bins are arranged in the refrigeration device 400, and different liquid materials can be stored in different material bins. The second pipeline is in one-to-one correspondence and communication with each material bin through a material conveying pipeline, so that different liquid materials can be conveyed. Due to the presence of the above multi-pipeline docking device, it also has the above beneficial effects. Other structures can refer to the prior art and will not be elaborated here.
[0062] In some embodiments, an avoidance hole is formed on the tabletop. The multi-pipeline docking device is arranged below the avoidance hole. The product output pipeline of the product output assembly passes through at the avoidance hole and is in communication with the multi-pipeline docking device. The setting of the avoidance hole can prevent the product output pipeline from being exposed, and since the product output pipeline does not need to bypass the tabletop, the extension length of the product output pipeline can be reduced.
[0063] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.
