[0042] Reference Figures 1 to 7 A water tank adapter 100, comprising:

[0043] The upper connecting part 110 is used to connect the water dispenser 310. The upper connecting part 110 has a first through hole 111 in the middle, which is used to allow the hose 311 of the water dispenser 310 to pass through.

[0044] The first threaded connection portion 120 is formed by extending the lower outer edge of the upper connection portion 110 downward to form a first threaded connection portion 120 with a first thread 121. The first threaded connection portion 120 is used to connect to the first threaded water inlet 410. The first threaded connection portion 120 has a first diameter.

[0045] The second threaded connection portion 130 is formed by the upper connection portion 110 extending downward around the first through hole 111 and having a second thread 131. The second threaded connection portion 130 is used to connect to the second threaded water inlet 420 and has a second diameter.

[0046] With the above-described structure, the water tank adapter 100 can simultaneously adapt to different water tank 400 water outlets. The upper connecting part 110 is used to connect the water dispenser 310 and allows its hose 311 to pass through. The first threaded connecting part 120 and the second threaded connecting part 130 have different diameters (first diameter and second diameter), which can respectively connect to the first threaded water outlet 410 and the second threaded water outlet 420 of different specifications. This achieves a multi-purpose connection with an integrated design, improving the versatility and adaptability of the device and meeting the needs of various usage scenarios. The design of separate and independent connecting parts allows users to quickly select the appropriate threaded connecting part for installation according to the water outlet of their water tank 400, without the need for additional accessories or complicated conversion processes, thus improving the convenience of use. Such a device is very user-friendly for people who enjoy outdoor sports, because the water tank adapter 100 can be adapted to most outdoor water tanks 400 on the market; in addition, the water tank adapter 100 is also compatible with most household water tanks 400. In use, the user can connect the first thread 121 or the second thread 131 to the corresponding water outlet according to the different water outlets of the water tank 400, thereby completing the connection between the water tank adapter 100 and the water tank 400.

[0047] In this embodiment, the first thread 121 is an internal thread, and the first threaded water inlet 410 is an external threaded water inlet. The first thread 121 is threadedly connected to the first threaded water inlet 410. Through the above structural arrangement, as... Figure 2 and Figure 5 As shown, the first thread 121 is configured as an internal thread and threadedly connected to the first threaded water inlet 410, which has an external thread. This allows for quick adaptation and stable connection with most water tanks 400 on the market. This design not only improves the versatility and compatibility of the water tank adapter 100 but also simplifies the installation process and enhances the user experience.

[0048] In this embodiment, the second thread 131 is an internal thread, and the second thread water inlet 420 is an external thread water inlet; the second thread 131 and the second thread water inlet 420 are threadedly connected. Through the above structural arrangement, as... Figure 2 and Figure 6As shown, the second thread 131 is configured as an internal thread and mates with the second threaded water inlet 420, which has an external thread structure. This allows for further adaptation to different models of water tanks 400, enhancing the stability and sealing of the connection between the water tank 400 and the water tank adapter 100. This design not only improves the overall structural reliability but also expands the applicability of the water tank adapter 100, making it easier for users to flexibly install and replace the adapter 100 with different water inlets of their water tanks 400, thus improving ease of use and adaptability.

[0049] In this embodiment, the first diameter is larger than the second diameter. Through the above structural arrangement, as... Figure 1 As shown, the first diameter is larger than the second diameter, which means that the first threaded connection 120 is larger than the second threaded connection 130. The water tank adapter 100 is a single unit, with the second threaded connection 130 located within the first threaded connection 120, forming a nested design. This design not only effectively saves space and improves the overall compactness of the water tank adapter 100, but also gives it greater flexibility and stability when adapting to the water inlets of different sized water tanks. Simultaneously, this nested design also helps improve the alignment between the water tank adapter 100 and the water tank 400 during connection, preventing water leakage from the connection point during dispensing, further enhancing safety and reliability.

[0050] In this embodiment, the first threaded connection portion 120 and the second threaded connection portion 130 are concentrically arranged. This structural arrangement ensures that the first threaded connection portion 120 and the second threaded connection portion 130 have a unified axis, guaranteeing the overall structural balance of the water tank adapter 100 and thus ensuring smooth water flow and efficient transmission. The concentric design also improves the stability and sealing of the overall assembly, avoiding problems such as stress concentration, poor sealing, or installation difficulties caused by eccentric connections.

[0051] In this embodiment, when the first threaded connector 141 is connected to the second threaded connection portion 130, the second threaded connector 142 protrudes from the lower edge of the first threaded connection portion 120 and the second threaded connection portion 130. Through the above structural arrangement, as... Figure 3As shown, the connecting straight-through 140 is a one-piece design, creating a stable fluid channel between the first threaded connector 141 and the second threaded connector 142, effectively avoiding the water leakage risk that may exist in traditional split structures. At the same time, the one-piece structure simplifies the assembly process and improves the stability and durability of the connecting straight-through 140 during long-term use. Combined with the prominent design of the second threaded connector 142, it not only improves the ease of connection between the connecting straight-through 140 and the water tank 400, but also facilitates the quick connection and disassembly of the connecting straight-through 140 and the second threaded connection part 130, achieving efficient, reliable, and easy-to-maintain performance.

[0052] In this embodiment, the first threaded connector 141 has an external thread, and it is threadedly connected to the second thread 131. Through this structural arrangement, the externally threaded first threaded connector 141 and the internally threaded second thread 131 achieve a tight fit, ensuring a secure connection, easy assembly and disassembly, and good sealing performance. The threaded connection not only improves the stability and pressure resistance of the connection point but also facilitates quick replacement or maintenance by the user according to actual needs, enhancing the practicality and adaptability of the overall structure. Furthermore, the combination of internal and external threads also enhances guidance and alignment during assembly, further ensuring the safety and reliability of fluid transmission.

[0053] In this embodiment, the second threaded connector 142 has an external thread, and the third threaded water inlet 430 has an internal thread. The second threaded connector 142 is used for threaded connection with the third threaded water inlet 430. Through the above structural arrangement, as... Figure 7 As shown, for some water tanks 400 on the market where the third threaded water inlet 430 uses an internal thread design, the second threaded connector 142, which serves as the intermediate bridge between the straight-through 140 and the water tank 400, adopts an external thread structure to achieve a reliable fit. In this case, firstly, the second threaded connector 142 connecting the straight-through 140 is threadedly connected to the third threaded water inlet 430. At this time, the first threaded connector 141 protrudes from the water inlet plane of the water tank 400. Then, the first threaded connector 141 is threadedly connected to the second thread 131 of the second threaded connection part 130. At this time, the connection between the straight-through 140 and the water tank adapter 100 is completed.

[0054] In this embodiment, the diameter of the first threaded water inlet 410 is 2.05 inches, and the first thread 121 is adapted to the 2.05-inch first threaded water inlet 410. With the above structural design, considering that a significant portion of the water inlets of commercially available water tanks 400 have 2.05-inch external threads, the first thread 121 adopts a 2.05-inch internal thread design to achieve effective connection between the two. Preferably, considering the non-standard nature of the threads of most water tank 400 water inlets, this 2.05-inch first thread 121 has been specially improved by reducing the number of thread turns. This design increases the adaptability of the first thread 121, so the first thread 121 can also adapt to Chinese threads of φ50-φ54, improving the versatility of the first threaded connection 120.

[0055] In this embodiment, the diameter of the second threaded water outlet 420 is 3 / 4 inch, and the second thread 131 is adapted to the 3 / 4-inch second threaded water outlet 420. With the above structural configuration, some water tanks 400 on the market still have a 3 / 4-inch external threaded water outlet 420. The second thread 131 needs to be connected to the second threaded water outlet 420 before the user can draw water from the water tank 400. Preferably, the number of thread turns of the second thread 131 can be reduced accordingly to increase the adaptability of the second thread 131 to non-standard threaded water outlets.

[0056] In this embodiment, the diameter of the third threaded water outlet 430 is 3 / 4 inch, and the second threaded connector 142 is adapted to the 3 / 4 inch third threaded water outlet 430. With the above structural design, considering that some users' water tanks 400 have a 3 / 4 inch internal thread third threaded water outlet 430, in this case, it is necessary to thread the second threaded connector 142 to the third threaded water outlet 430, and then thread the first threaded connector 141 to the second thread 131 of the second threaded connection part 130, so that the user can obtain water from the 3 / 4 inch internal threaded water outlet.

[0057] A water tank adapter 200 includes:

[0058] The water tank adapter 100 as described above;

[0059] The cover 210 is fitted onto the upper end of the upper connecting part 110. The cover 210 has a second through hole 211 in the middle, which is used to allow the hose 311 of the water dispenser 310 to pass through.

[0060] With the above-described structure, the cover 210 fits over the upper connecting portion 110 of the water tank adapter 100. The cover 210 effectively seals the top opening of the water tank adapter 100 in both active and inactive states, preventing external impurities, dust, or contaminants from entering the cavity 112 of the upper connecting portion 110. It also reduces the difficulty of cleaning the water tank adapter 100 when not in use. The second through hole 211 allows the hose of the water tank 400 to pass through it. Accordingly, during water dispensing, the cover 210 remains closed over the upper connecting portion 110. This design ensures the positional stability of the hose 311 during assembly, further enhancing the functional integrity and safety of the overall structure. Simultaneously, the second through hole 211 provides good installation guidance for the hose 311, facilitating assembly and disassembly, and improving user convenience and maintenance efficiency. Preferably, the cover 210 can be the lid of the water tank 400. For some five-gallon water buckets, the lid itself has a through-hole design, so the lid of the five-gallon water bucket can be used directly as a lid210, simplifying the structure and reducing costs.

[0061] Preferably, the size of the cover 210 matches the size of the upper connecting part 110. Through this structural arrangement, the cover 210 can achieve a tight fit with the upper connecting part 110, ensuring its stability and sealing in the closed state and preventing closure failure due to loosening or misalignment.

[0062] Preferably, the upper connecting portion 110 is provided with a cavity 112, which communicates with the first through hole 111. With this structure, some covers 210 are embedded, allowing a portion of the cover 210 to extend into the cavity 112, thus ensuring smooth connection and sealing of the entire device. Simultaneously, when not in use, a portion of the hose 311 can be stored within the cavity 112. Preferably, the upper end of the upper connecting portion 110 is an open design. This open design allows a portion of the cover 210 to be detachably inserted into the cavity 112 of the upper connecting portion 110. Furthermore, during actual use or cleaning and maintenance, the open structure also helps improve the cleanability of the internal space of the upper connecting portion 110, reducing hygiene risks caused by residual liquid, and further enhancing the safety and service life of the water tank adapter 100.

[0063] A water intake adapter 300 includes:

[0064] The water tank adapter 100 as described above;

[0065] Water dispenser 310, the water dispenser 310 is provided with a hose 311, the hose 311 passes through the second through hole 211 and the first through hole 111 to enter the water tank 400.

[0066] With the above-described structure, the water dispenser 310 and its hose 311 serve as the key medium for water circulation. The water dispenser 310, in conjunction with the water tank adapter 100, helps outdoor users achieve stable water access. The lid 210 ensures hygiene during the water dispensing process. Optionally, a lid 210 may also be included. In use, if the water outlet of the water tank 400 has an internal thread design, the second threaded connector 142 of the connecting straight-through 140 must first be threaded to the third threaded water outlet 430. Then, the first threaded connector 141 must be threaded to the second thread 131 of the second threaded connection 130. Next, the hose 311 of the water dispenser 310 is passed sequentially through the second through hole 211, the first through hole 111, and the connecting straight-through 140 to enter the water tank 400. These steps allow the user to configure the internal threaded water outlet. The design allows for quick water dispensing from the water tank 400. If the water dispensing port of the water tank 400 has an external thread design, the user can connect the first thread 121 or the second thread 131 to the corresponding water dispensing port according to the different sizes of the water tank 400's first thread water dispensing port 410 or second thread water dispensing port 420. Then, the hose 311 of the water dispenser 310 is passed through the second through hole 211 and the first through hole 111 in sequence to enter the water tank 400. Through the above steps, the user can quickly dispense water from the water tank 400 with an external thread water dispensing port design.

[0067] Preferably, the dimensions of the hose 311 match the dimensions of the second through hole 211, the first through hole 111, and the connecting straight section 140. Through this structural arrangement, the hose 311 plays a crucial role in guiding and transmitting liquid throughout the process of the user drawing water from the water tank 400. One end of the hose 311 is located inside the water tank 400, with its tip submerged below the liquid surface to ensure proper water intake. The other end may pass through the second through hole 211, the first through hole 111, and the connecting straight section 140 to connect to the water dispenser 310, thereby enabling the user to draw water stably and efficiently from the water tank 400. The hose 311 has good dimensional compatibility with each through hole, ensuring not only smoothness and sealing during installation and water drawing but also effectively preventing problems such as leakage, blockage, or unstable flow during liquid transmission.
