Description

Technical Field

[0001] This utility model relates to the field of large-diameter connectors, and in particular to a structure for a large-diameter quick-cleaning connector. Background Technology

[0002] Quick-connect couplings are key devices for feeding ingredients in tea beverage machine management systems. In the tea beverage machine piping system, due to the need to change ingredients and clean the pipes, liquid needs to be switched between ingredients and water. This requires one coupling installed on the ingredient box, one coupling connected to water, and another coupling connected to the water pump at one end, allowing switching between the two couplings. When these couplings are used independently, they need to be self-sealing and leak-proof.

[0003] While traditional quick connectors solve the problems of rapid switching and self-sealing, their structural limitations mean that the liquid comes into contact with the spring during use. This is especially true for fruit juices and jams containing flocculent material, which can leave liquid residue in the spring gaps that is difficult to clean, posing a food safety hazard. Furthermore, existing quick connectors have many obstructions in the liquid channel, resulting in poor liquid flow efficiency and preventing some functions of the tea maker from being fully utilized. Therefore, a large-diameter quick-cleaning connector structure is proposed to solve the above problems. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example 1:

[0042] Reference Figures 1-3 This utility model provides an embodiment of a large-diameter quick-cleaning connector structure, including a connector a1 as the front-end connecting component of the entire connector structure. The inner wall of the connector a1 is threadedly connected to a housing A4, which can be quickly disassembled through the thread and also serves to fix the housing A4. The surface of the housing A4 is provided with an installation groove a401, a sealing surface a402, and a retaining groove 403. A sealing ring b3 is provided on the inner wall of the installation groove a401, which slides and seals the inner wall of the connector a1 to seal the connection between the housing A4 and the connector a1. A valve core A7 is movably connected to the inner wall of the housing A4. An installation groove c702 is opened in the middle of the valve core A7 for installing a sealing ring c5, which cooperates with the sealing surface a402 to achieve a seal. The sealing ring c5 is provided on the inner wall of the installation groove c702, which, along with the valve core A7, plays a sealing role in the housing A4 to prevent liquid leakage in the gap between the valve core A7 and the housing A4. The sealing ring c5 is piston-connected to the inner wall of the sealing surface a402. A housing B11 is snapped into the inner wall of the rear side of the housing A4.

[0043] Reference Figure 2 , Figure 10 and Figure 11 The outer casing B11 has a connecting post a1102 and a sealing surface b1103 on its surface. A slot 403 is L-shaped, and the connecting post a1102 is engaged with the inner side of the slot 403. The slot 403 is used to engage with the connecting post a1102 on the outer casing B11, enabling quick connection and disassembly of the outer casing A4 and outer casing B11. This is achieved through a rotating snap-fit ​​design, facilitating the assembly and disassembly of the connector. A valve core B9 is connected to the inner wall of the sealing surface b1103 via a sealing ring e10. A sealing ring d8 is provided on the front side of valve core B9 and the rear side of valve core A7 to seal the connection between valve core A7 and valve core B9, preventing liquid from flowing between them. To prevent leakage between the valve cores, springs 6 are fitted on the front of valve core A7 and the outer side of valve core B9 to provide a restoring force for valve cores A7 and B9. When the joint is connected or disconnected, springs 6 push the valve cores to move, realizing the self-sealing function of the joint and preventing liquid leakage. The rear side of the outer shell B11 is threaded with a connector b13 for connecting to external equipment such as water pipes or water pumps. The rear side is designed to be protruding for easy installation and docking. A sealing ring f12 is provided at the connection between the rear side of the outer shell B11 and the inner wall of the connector b13 to seal the connection between the outer shell B11 and the connector b13 and prevent liquid leakage.

[0044] Reference Figure 2 , Figure 6 and Figure 7 The valve core A7 has a mounting groove b701 on its front side and a mounting groove d901 on its rear side. Both mounting grooves b701 and d901 have sealing rings a2 on their inner walls. The valve core B9 has a mounting groove e902 on its outer side for mounting a sealing ring e10, which cooperates with the sealing surface b1103 to achieve a seal. The sealing ring e10 is located on the inner wall of the mounting groove e902 and the inner wall of the sealing surface b1103. It moves with the valve core B9 within the outer shell B11 to provide a seal and prevent liquid leakage between the valve core B9 and the outer shell B11. The diameter of the front side of the valve core B9 is larger than the diameter of the rear side.

[0045] Reference Figure 2 , Figure 8 and Figure 9 The valve core B9 has a contact surface b904 on its outer side, which contacts the outer side of the spring 6, supporting the spring 6 and transmitting its elastic force. A fluid guide plate b903 is provided on the rear side of the valve core B9 to guide the flow direction of the fluid. Together with the fluid guide plate a703, they make the fluid flow more smoothly within the joint, reducing resistance and improving liquid throughput efficiency.

[0046] Reference Figure 2 , Figure 4 and Figure 5The mounting groove a401 is located on the outer front of the housing A4 for installing the sealing ring b3 to achieve a seal when the housing A4 is connected to the connector a1. The slot 403 is located through the rear of the housing A4. The sealing surface a402 is located on the inner wall of the housing A4 and is set as a smooth cylindrical surface. It cooperates with the sealing ring c5 to achieve a seal of the valve core A7 inside the housing A4, separating the internal space of the valve core A7 from the housing A4, so that the spring 6 is in the sealed space. The front side of the valve core A7 is fixedly connected to an inclined fluid guide plate a703 to guide the flow direction of the fluid, reduce fluid resistance, and allow the fluid to pass through the connector more smoothly, thereby improving the liquid flow efficiency. The diameter of the valve core A7 decreases stepwise from front to back. The outer side of the valve core A7 is provided with a contact surface a704, which contacts the outer side of the spring 6 and plays the role of supporting the spring 6 and transmitting elastic force.

[0047] Reference Figure 10 , Figure 11 and Figure 12 The connecting column a1102 is fixedly connected to the arc surface of the outer shell B11 and engages with the slot 403 of the outer shell A4, enabling quick connection and disassembly of the outer shell A4 and the outer shell B11. The sealing surface b1103 is located on the inner wall of the outer shell B11 and is set as a smooth cylindrical surface. It cooperates with the sealing ring e10 to achieve sealing when the valve core B9 moves inside the outer shell B11, sealing the moving space of the spring 6, thereby preventing the liquid in the quick connector from contacting the spring 6. The outer middle of the outer shell B11 is set as a regular hexagon. The rear side of the outer shell B11 is provided with a threaded groove. The inner wall of the rear side of the outer shell B11 is fixedly connected to a fixing ring 1101, which contacts the outer side of the valve core B9. The front and rear parts of the valve core B9 and the valve core A7 are connected, reducing the obstruction structure in the liquid channel and forming a large-diameter fluid channel, allowing the liquid to pass through the connector more smoothly and improving the liquid flow efficiency. The front side of the connector a1 and the rear side of the connector b13 are set as protrusions, which facilitates the installation and docking of hoses.

[0048] Example 2:

[0049] Reference Figure 13 The difference between this embodiment and embodiment one is that in embodiment two, nut 14 is used to replace connector b13, thereby changing the installation method of the device and thus improving the applicability of the device.

[0050] Example 3:

[0051] Reference Figure 14 and Figure 15The difference between this third embodiment and the first embodiment is that the connector b13 in the first embodiment can be replaced by the outer shell C15, and the valve core B9 is removed. The outer wall of the front side of the outer shell C15 is fixedly connected to the connecting column b1502, which has the same function as the connecting column a1102. The inner wall of the outer shell C15 is provided with a mounting plate 1501 for installing and fixing the sealing ring d8 to ensure the sealing performance of the valve core A7. At the same time, the device is installed through the thread on the outer shell C15, which improves the applicability of the device.

[0052] Working principle: During installation, connect the outer shell A4 to the connector a1 by thread and seal it with the sealing ring b3. Then, install the sealing ring c5 on the inner wall of the mounting groove b701 of the valve core A7, and put the spring 6 on the outside of the valve core A7. Insert the sealing ring c5 and the spring 6 into the inner wall of the outer shell A4. The sealing ring c5 and the sealing surface a402 are squeezed and sealed, and the spring 6 is isolated from the liquid being transported, such as juice or water, to prevent liquid residue and contamination.

[0053] Similarly, install the sealing ring e10 in the mounting groove e902 on the valve core B9, and fit the spring 6 on top. Insert the valve core B9 into the outer shell B11 so that the sealing ring e10 contacts the sealing surface b1103, thereby isolating the spring 6 from contact with the conveyed liquid, such as juice or water, to prevent liquid residue and contamination.

[0054] At the same time, the front and rear parts of valve core A7 and valve core B9 are connected. The sealing ring d8 is placed on the opposite side of valve core A7 and valve core B9 to form a complete large-diameter fluid channel. Then, the connecting post a1102 of the outer shell B11 is aligned with the L-shaped groove 403 of the outer shell A4. After insertion, the outer shell B11 is rotated so that the connecting post a1102 is inserted into the horizontal section of the groove 403, achieving quick fixation. The sealing ring d8 is compressed when valve core A7 and valve core B9 come into contact, forming a seal.

[0055] When disassembly and maintenance are required, rotate housing B11 in the reverse direction to disengage connecting post a1102 from slot 403, and housing A4 and housing B11 can be quickly separated without tools, making the operation convenient.

[0056] Replacing connector b13 with nut 14 is suitable for installation scenarios requiring threaded fastening, improving installation flexibility. Replacing connector b13 with housing C15 and removing valve core B9 is suitable for scenarios with unidirectional fluid channels. The sealing ring d8 is fixed by mounting plate 1501 to ensure sealing performance.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
