[0012] On the basis of the above technical solution, preferably, the air cavity is filled with an inert gas.

[0013] On the basis of the above technical solution, preferably, the width of the annular groove is greater than the width of the airbag after it is fully inflated.

[0014] On the basis of the above technical solution, preferably, the front end of the water supply pipe joint extends forward to form a tubular structure, wherein: The side of the tubular structure is provided with a water supply channel connection port; The front end of the ejector pin passes through the rear end of the water supply pipe joint and extends to the inner side of the tubular structure; A nut portion is provided at the rear end of the ejector pin, and a stud portion is provided at the rear end of the water supply pipe joint. The nut portion is threadedly connected to the stud portion to adjust the length of the ejector pin extending into the tubular structure.

[0015] On the other hand, the present invention also provides a method for installing a quick-detachable water supply tank, which is applied to the above-mentioned quick-detachable water supply tank and includes the following steps: S1. Flip open the flip clamping mechanism so that the clean water tank is horizontally embedded in the water tank fixing slot in the installation cabinet along the front-to-back direction; S2. During the insertion of the clean water tank, the front end of the water supply sub-connector is automatically inserted into the rear end of the water supply female connector and the water supply channel is automatically connected.

[0016] The quick-detachable water supply tank and its installation method of the present invention have the following beneficial effects compared with the prior art: (1) By setting a fixed slot for the water tank in the installation cabinet and limiting the clean water tank to be inserted into the slot only from the front to the back, and then positioning and fixing the clean water tank through a flip clamping mechanism, the clean water tank is effectively limited in the up and down, left and right, and front and back directions, thereby significantly enhancing its anti-vibration ability and effectively preventing sealing failure and water leakage caused by flight vibration. At the same time, the water supply sub-connector and the water supply main connector can realize automatic conduction and airtight connection of the water supply channel during the clean water tank insertion process, and the plug-in and sealing operations can be completed without manual intervention by the operator in a limited space, further improving the convenience of clean water tank replacement and the reliability of system operation. In addition, the plug-in structure between the water supply sub-connector and the water supply main connector cooperates with the linkage sealing mechanism, which not only realizes quick connection, but also further enhances the stability and sealing safety of the overall structure, effectively avoiding the risk of leakage caused by vibration.

[0017] (2) By setting the valve core to act on the air cavity and the water cavity at the same time, the airbag and the valve core are mechanically linked, and the water supply channel can be opened and the airtight seal can be completed simultaneously during the insertion of the clean water tank. When the clean water tank is inserted, the ejector pushes the valve core forward, opens the water supply channel and drives the airbag to expand to form a seal; when the clean water tank is removed, the valve core returns to its original position, cuts off the water supply and releases the airbag pressure. This linkage mechanism realizes the full automatic control of the plug-in and pull-out operation, improves the system sealing performance and ease of use. Moreover, during the insertion and removal of the clean water tank, the airbag slowly expands or releases pressure, reducing its resistance to the water supply joint, making the insertion and removal operations easier and smoother.

[0020] The following will be combined with the specific embodiments of the present invention to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-6 As shown, a quick-detachable water supply tank of the present invention is a detachable cabinet combination structure, which includes an installation cabinet 2 fixed in the aircraft bathroom or kitchen, and a fresh water tank 1 arranged in the installation cabinet 2.

[0022] Among them, a water tank fixing slot is provided inside the installation cabinet 2, and the clean water tank 1 can only be embedded in the water tank fixing slot from front to back, and the embedded position is fixed by a flip clamping mechanism 21; a water supply female connector 11 is provided on the back of the clean water tank 1, and a water supply sub-connector 22 is provided on the inside of the installation cabinet 2. When the clean water tank 1 is embedded in place, the front end of the water supply sub-connector 22 is automatically inserted into the rear end of the water supply female connector 11 and automatically opens the water supply channel, and the two automatically form an airtight connection through the linkage sealing structure during the insertion process.

[0023] The water supply sub-connector 22 and the water supply main connector 11 are automatically connected by the guidance of the water tank fixed slot. When the clean water tank 1 is inserted into the slot from front to back, the flip clamping mechanism 21 fixes the position of the clean water tank 1 after insertion, so that the water tank can achieve multi-dimensional limitation in the up and down, left and right, and front and back directions through the cooperation of the water tank fixed slot and the flip clamping mechanism 21, thereby enhancing the vibration resistance and effectively preventing the sealing failure and water leakage caused by vibration. At the same time, the water supply sub-connector 22 and the water supply main connector 11 can automatically conduct the water supply channel and form an airtight connection, and the plugging and sealing operations can be completed without excessive manual intervention, thereby improving the convenience of replacing the clean water tank 1.

[0024] In this quick-detachable water supply tank, the flip clamping mechanism 21 includes two structural forms, one of which is: the flip clamping mechanism 21 includes an upper baffle 211, and the upper end of the upper baffle 211 is connected to the top of the front side of the installation cabinet 2 by a hinge to form an up and down flip mechanism; the side of the upper baffle 211 is connected to the side of the installation cabinet 2 by a lock to achieve position locking, and the rear end of the upper baffle 211 is abutted against the front end of the clean water tank 1 to limit the displacement of the clean water tank 1 in the front and rear directions.

[0025] The lock adopts a traditional mechanical lock with a handle, and its lock body is fixed on the upper baffle 211. A lock tongue fixing groove that cooperates with the lock body is provided at the corresponding position of the installation cabinet 2; the operator can operate the handle to make the lock tongue enter or exit the lock tongue fixing groove, thereby realizing the locking or unlocking operation of the upper baffle 211, and then completing the rapid fixing or release of the clean water tank 1.

[0026] In another structural form, the flip clamping mechanism 21 includes a spring hinge 212, a handle 213 and an elastic limiter 214, wherein the lower end of the handle 213 is hinged to the bottom of the front side of the installation cabinet 2 through the spring hinge 212 to form an up and down flip mechanism; the elastic limiter 214 is fixed to the upper end of the handle 213, and its rear end is abutted against the front end of the clean water tank 1.

[0027] Specifically, one end of the spring hinge 212 is fixedly connected to the bottom of the front side of the installation cabinet 2, and the other end is fixedly connected to the lower end of the handle 213, so that the handle 213 can be flipped up and down through the spring hinge 212 to form a stable opening and closing mechanism; the end of the handle 213 connected to the spring hinge 212 is the hinge end, and the end connected to the installation cabinet 2 is the flip end. After flipping the flip end of the handle 213 upward, the elastic limiter 214 can be used to press the clean water tank 1 backward to limit the displacement of the clean water tank 1 in the front and rear directions.

[0028] The spring hinge 212 is a common home hardware component with an automatic rebound function. It supports both fully open and fully closed states, and automatically closes in the middle position, thereby providing a stable closing elastic force for the handle 213. The elastic limiter 214 is preferably a rubber block with good cushioning properties and friction. It can exert continuous pressure on the clean water tank 1 when the handle 213 is closed, enhancing clamping stability. Before the clean water tank 1 is inserted, the operator flips the handle 213 downward, opens it, and maintains it in a horizontal position. After the clean water tank 1 is inserted into place, the handle 213 is flipped upward to close it and fit it against the front end of the clean water tank 1. At this time, the elastic force of the spring hinge 212 causes the elastic limiter 214 to press against the front end of the clean water tank 1, achieving a quick and stable locking.

[0029] The two flipping and clamping mechanisms 21 described above can be used simultaneously or separately in the water supply tank. By using the flipping and clamping mechanisms 21, the clean water tank 1 can be securely fixed in the tank fixing slot, effectively preventing loosening or falling off due to vibration during flight, and significantly improving the stability and safety of the overall structure.

[0030] In this quick-detachable water supply tank, the top of the clean water tank 1 is against a vertical limit block 12, the back is against an anti-collision block 13, one side is against an anti-wear strip 14, the other side is against a partition 15, and the bottom is against a support bar 16, wherein the vertical limit block 12, anti-collision block 13, anti-wear strip 14, partition 15 and support bar 16 are all fixed inside the installation cabinet 2; the space enclosed between the vertical limit block 12 and the anti-collision block 13, anti-wear strip 14, partition 15 and support bar 16 constitutes a fixed slot of the water tank.

[0031] This structure limits and protects the clean water tank 1 from multiple directions, including the top, back, sides, and bottom. Combined with the tilting clamping mechanism 21, this achieves multi-dimensional, stable positioning of the clean water tank 1 in the vertical, left-right, and front-back directions. This structure effectively reduces shaking caused by vibration or impact during flight, prevents sealing failure or damage to the tank, and significantly improves the reliability of the clean water tank 1 installation and the overall safety of the system.

[0032] Furthermore, multiple support bars 16 are arranged side by side in the left-right direction. They are preferably made of the same flexible, wear-resistant material as the anti-wear bars 14, such as polyurethane. The presence of multiple support bars 16 increases the force-bearing area at the bottom of the clean water tank 1, ensuring a more even distribution of force and preventing localized deformation or sinking. This structure also effectively disperses the vibration and impact forces generated during flight, further enhancing the stability and service life of the clean water tank 1.

[0033] In the quick-detachable water supply tank, the water supply female connector 11 includes a valve body 111 and a valve core 112, and the water supply sub-connector 22 includes a water supply pipe connector 221 and a thimble 222. The valve body 111 is provided with a water inlet connector insertion hole 1111, a tapered hole 1112, an inner cavity 1113, a guide sleeve 1114 and a water tank connection hole 1115 in sequence from back to front; the guide sleeve 1114 is coaxially fixed to the front end of the air cavity 11131, and a return sleeve is provided on its inner side. The valve core 112 is arranged in the inner cavity 1113, and is connected to the inner cavity 1113 in a sliding and sealing manner through the first piston ring 114. The first piston ring 114 divides the inner cavity 1113 into a front air cavity 11131 and a rear water cavity 11132. The rear end of the valve core 112 is a conical structure, which is a conical sealing structure. The sealing ring 115 is used to seal the valve core 112 and the tapered hole 1112. The front end of the valve core 112 is a tubular structure, and the guide sleeve The rear end of 1114 is sleeved on the inner side of the tubular structure, and the two are slidably and sealedly connected by the second piston ring 116; the rear end of the tubular structure elastically abuts against the front end of the return spring 113, and a connecting hole 1121 connected to the water cavity 11132 is provided on the side wall of the tubular structure; an annular groove 11111 is provided inside the water inlet joint insertion hole 1111, and an air bag 117 is provided inside the annular groove 11111, and the air bag 117 is connected to the air cavity 111 through the air channel 1116. 31; The water supply pipe joint 221 is fixed to the installation cabinet 2, one side of which is connected to the water supply channel, and the front end is inserted into the water inlet joint insertion hole 1111 and connected; the ejector pin 222 is provided on the inner side of the water supply pipe joint 221, and is used to push the valve core 112 forward so that the water supply pipe joint 221 is connected with the water cavity 11132, and the gas in the air cavity 11131 is injected into the air bag 117 to form a sealing structure between the water supply pipe joint 221 and the water inlet joint insertion hole 1111.

[0034] In this structure, air passage 1116 is provided on valve body 111, one end of which connects to airbag 117 and the other end to air cavity 11131. Sealing ring 115 is fixed inside the tapered structure. In the initial state, the tapered structure at the rear end of valve core 112 abuts against sealing ring 115, sealing tapered hole 1112. When the water path is open, water in clean water tank 1 passes through water tank connection hole 1115, guide sleeve 1114, the tubular structure of valve core 112, connecting hole 1121, and tapered hole 1112 in sequence, entering water supply pipe connector 221.

[0035] The outer surface of the valve core 112 is provided with a plurality of annular piston grooves for mounting a first piston ring 114. The first piston ring 114 realizes a sliding and sealed connection between the valve core 112 and the inner cavity 1113. Similarly, the outer surface of the guide sleeve 1114 is provided with a plurality of annular piston grooves for mounting a second piston ring 116. The second piston ring 116 realizes a sliding and sealed connection between the valve core 112 and the guide sleeve 1114. The sliding seal structure is similar to the piston structure within a cylinder. The piston ring is a metal elastic ring with a large outward expansion and deformation capability in the prior art. It is usually assembled in an annular groove that matches its cross-sectional shape and is commonly found in cylinder piston structures. During reciprocating or rotational motion, the piston ring relies on the pressure difference of the gas or liquid to form an effective seal between its outer circumferential surface and a mating component such as the inner wall of a cylinder or valve body, and between the piston ring and one side of the groove.

[0036] This invention utilizes existing piston ring structures in the mating areas between valve core 112 and inner cavity 1113, and between valve core 112 and guide sleeve 1114, achieving dynamic sealing between key fluid passages and improving the overall sealing performance and operational stability of the joint structure. Because the piston ring structure is a mature technology, its specific structure and principles will not be elaborated upon here.

[0037] The airbag 117 and the valve core 112 together constitute a linkage sealing structure, wherein the valve core 112 can act on the air cavity 11131 and the water cavity 11132 at the same time, so that the conduction of the water supply channel and the formation of the airtight sealing structure can be completed simultaneously during the embedding process of the clean water tank 1, thereby realizing the automatic control of the plugging and unplugging operations of the clean water tank 1.

[0038] Specifically, the linkage process of the above-mentioned linkage sealing structure is as follows: when the clean water tank 1 is inserted into place, the ejector pin 222 in the water supply sub-connector 22 pushes the valve core 112 forward, the tapered hole 1112 is opened, the water cavity 11132 is connected, and the water supply channel is established; at the same time, the valve core 112 compresses the gas in the air cavity 11131 and injects the gas into the air bag 117 through the air channel 1116, causing the air bag 117 to expand, forming a reliable airtight seal between the water supply pipe connector 221 and the water inlet connector insertion hole 1111. When the clean water tank 1 is withdrawn, the valve core 112 automatically resets under the action of the return spring 113, re-blocking the tapered hole 1112 and cutting off the water supply channel; at the same time, negative pressure is generated inside the air cavity 11131, and air is sucked in to cause the air bag 117 to decompress and return to its initial state.

[0039] Through the above-mentioned linkage mechanism, the plugging and unplugging process of the two water supply joints is fully automated, ensuring reliable sealing and rapid opening and closing without additional operation, which significantly improves the safety, stability and ease of use of the system.

[0040] Furthermore, during insertion and removal of the clean water tank 1, the airbag 117 gradually expands or releases pressure through the injection or release of gas, preventing excessive resistance to the water supply pipe connector 221 caused by sudden pressure changes. This progressive sealing and release mechanism effectively reduces friction and resistance during insertion and removal, making installation and removal of the clean water tank 1 smoother and more comfortable, improving overall operational comfort and system reliability.

[0041] Air cavity 11131 is filled with an inert gas, such as nitrogen or argon. These gases exhibit excellent compressibility and resilience, allowing them to be stably injected into airbag 117 under the action of valve core 112, thereby maintaining the stability of the sealing structure during long-term use. Furthermore, inert gases are chemically stable and less susceptible to oxidation or corrosion, thus enhancing the safety and durability of the entire water supply connector system.

[0042] Furthermore, the width of the annular groove 11111 is greater than the maximum width of the airbag 117 when fully inflated, ensuring that the airbag 117 is not restricted by the space in the annular groove 11111 during operation. This structure ensures that the airbag 117 has sufficient deformation space, thereby maintaining its good elastic deformation ability and sealing performance, and avoiding sealing failure or structural damage due to restricted extrusion.

[0043] In this structure, the front end of the water supply pipe connector 221 extends forward into a tubular structure, with a T-shaped support structure at its bottom to enhance connection stability and facilitate installation and positioning. The side of the tubular structure is provided with a water supply channel connection port 2211 for connecting to an external water supply system; the front end of the ejector pin 222 passes through the rear end of the water supply pipe connector 221 and extends to the inside of the tubular structure, used to push the valve core 112 forward during the insertion of the clean water tank 1, thereby opening the water supply channel; the rear end of the ejector pin 222 is provided with a nut portion 2221, and the rear end of the water supply pipe connector 221 is provided with a stud portion 2212. The nut portion 2221 and the stud portion 2212 are threadedly connected to each other to adjust the length of the ejector pin 222 extending into the tubular structure.

[0044] Through the above structure, the water supply pipe connector 221 can be precisely docked with the water supply female connector 11; at the same time, the ejector pin 222 can flexibly adjust the extension length according to actual assembly requirements through the thread adjustment function between the nut portion 2221 and the stud portion 2212, thereby ensuring the accuracy and consistency of the valve core 112 movement and improving the stability and adaptability of the entire quick-release connector system.

[0045] like Figure 1-6 As shown, a method for installing a quick-detachable water supply tank of the present invention comprises the following steps: S1. The operator first flips and opens the flip clamping mechanism 21, so that the clean water tank 1 is horizontally embedded in the water tank fixing slot in the installation cabinet 2 along the front-to-back direction; S2. During the insertion of the clean water tank 1, the front end of the water supply sub-connector 22 provided inside the installation cabinet 2 is automatically inserted into the rear end of the water supply female connector 11 on the back of the clean water tank 1, thereby automatically opening the water supply channel and automatically forming an airtight connection through the linkage sealing structure; S3. When the clean water tank 1 is fully embedded in place, the flip clamping mechanism 21 is flipped over and closed so that its rear end abuts against the front end of the clean water tank 1, thereby firmly fixing the clean water tank 1 in the water tank fixing slot, completing the entire installation process.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
