[0029] like Figures 1 to 7 As shown, the utility model provides a capsule sealing mechanism for a water storage and supply device, which includes a high-pressure hydrogen cylinder 3, a built-in rubber capsule 2, and a shell 1 from the inside to the outside.

[0030] In the capsule sealing mechanism, the tail end of the high-pressure hydrogen cylinder 3 is covered with a capped round sleeve 31, and the head end of the high-pressure hydrogen cylinder 3 is fixedly connected with an air inlet and outlet metal nozzle 32;

[0031] In this embodiment, convex portions 21 are constructed at both ends of the built-in rubber bladder 2, and annular embedding grooves 33 corresponding to the convex portions 21 are constructed on the capped circular sleeves 31 and the inlet and exhaust metal nozzles 32 respectively provided at both ends of the high-pressure hydrogen cylinder 3. The inner side of the rear end of the built-in rubber bladder 2 is wedged with the capped circular sleeve 31, and the outer side of the rear end of the built-in rubber bladder 2 is abutted against the outer shell 1. The capped circular sleeve 31 is tightly connected to the outer shell 1, and the built-in rubber bladder 2 and the outer shell 1 are pressed tightly by the capped circular sleeve 31, so that the convex portion 21 of the built-in rubber bladder 2 and the annular embedding grooves 33 of the capped circular sleeve 31 remain in an embedded state. That is, within a range of 360°, the two sides of the rear end of the built-in rubber bladder 2 are tightly fitted with the capped circular sleeve 31 and the outer shell 1, thereby achieving a rear end seal between the capped circular sleeve 31, the built-in rubber bladder 2, and the outer shell 1.

[0032] The inner side of the head end of the built-in rubber bladder 2 is also wedged with the inlet and exhaust metal nozzle 32 via the protrusion 21 and the annular embedding groove 33. The outer side of the head end of the built-in rubber bladder 2 abuts against the outer shell 1. The metal nozzle locking piece is tightly connected to the inlet and exhaust metal nozzle 32 and abuts against the outer side of the outer shell 1. The outer shell 1, the built-in rubber bladder 2, and the inlet and exhaust metal nozzle 32 are compressed by the metal nozzle locking piece, so that the protrusion 21 of the built-in rubber bladder 2 and the annular embedding groove 33 on the inlet and exhaust metal nozzle 32 remain in an embedding state. That is, within a range of 360 degrees, both sides of the head end of the built-in rubber bladder 2 are tightly fitted with the inlet and exhaust metal nozzle 32 and the outer shell 1, achieving a head end seal among the inlet and exhaust metal nozzle 32, the built-in rubber bladder 2, and the outer shell 1.

[0033] The above-mentioned sealing structure forms a variable gas storage chamber 36 between the built-in rubber bladder 2 and the high-pressure hydrogen cylinder 3, and a variable water storage chamber 37 between the housing 1 and the built-in rubber bladder 2. The housing 1 is provided with a water outlet 11. The low-pressure gas flow channel 321 in the metal inlet and exhaust nozzle 32 is connected to the variable gas storage chamber 36, and the high-pressure gas flow channel 322 in the metal inlet and exhaust nozzle 32 is connected to the inner cavity of the high-pressure hydrogen cylinder 3. The low-pressure gas flow channel 321 and the high-pressure gas flow channel 322 are not connected to each other and are independent gas flow channels.

[0034] When water supply is needed, low-pressure gas enters the variable gas storage chamber 36 from the low-pressure gas flow channel 321. Under the action of the sealing structure, the low-pressure gas cannot be discharged from the area outside the low-pressure gas flow channel 321, which will only cause the volume of the variable gas storage chamber 36 to expand, and then squeeze the adjacent variable water storage chamber 37, and let the water in the variable water storage chamber 37 enter the lower-level water supply system from the water outlet 11; when gas supply is needed, the electric control valve is opened, and the high-pressure gas in the high-pressure hydrogen cylinder 3 enters the lower-level gas supply system through the high-pressure gas flow channel 322. With a good sealing structure, relatively independent water supply and gas supply functions can also be achieved.

[0035] Specifically, the annular embedding groove 33 of the capped circular sleeve 31 is constructed on the cap portion 311 of the capped circular sleeve 31 and is disposed facing the housing 1 .

[0036] Specifically, the annular embedding groove 33 of the intake and exhaust metal nozzle 32 is constructed on the bottom platform 39 of the intake and exhaust metal nozzle 32 and is arranged facing the housing 1 .

[0037] Specifically, the shell 1 includes a first shell section 13 and a tail shell section 14. After the tail end and the head end of the high-pressure hydrogen cylinder 3, the built-in rubber bag 2, and the shell 1 are sealed and assembled, the first shell section 13 and the tail shell section 14 are butt-welded.

[0038] Specifically, an external thread is constructed on the outer wall of the capped circular sleeve 31 , and an internal thread is constructed inside the corresponding shell 1 , so that the capped circular sleeve 31 and the shell 1 are fastened by a threaded connection.

[0039] Specifically, the metal nozzle locking member is a flange 34, the inner circumference of the flange 34 is constructed with an internal thread, and the outer circumference of the corresponding intake and exhaust metal nozzle 32 is constructed with an external thread, and the flange 34 and the intake and exhaust metal nozzle 32 are fastened by threaded connection.

[0040] Specifically, a sealing ring groove 312 is constructed on the inner circumferential surface of the capped circular sleeve 31, and a sealing ring 315 is also mounted on the tail end of the high-pressure hydrogen cylinder 3. The sealing ring 315 abuts between the sealing ring groove 312 and the tail end of the high-pressure hydrogen cylinder 3, thereby achieving sealing between the tail end of the high-pressure hydrogen cylinder 3 and the capped circular sleeve 31.

[0041] Specifically, the inlet and outlet ports of the low-pressure gas flow channel 321 and the inlet and outlet ports of the high-pressure gas flow channel 322 are respectively connected to a low-pressure gas pipe 41 and a high-pressure gas pipe 42. The low-pressure gas pipe 41 is connected to a low-pressure gas supply device, and the high-pressure gas pipe 42 is connected to an electric control valve, thereby realizing the inlet and outlet of high and low pressure gases.

[0042] The working principle and working process of this utility model are as follows:

[0043] When water supply is needed, low-pressure gas passes through the low-pressure gas duct 41 and the low-pressure gas flow channel 321 into the variable gas storage chamber 36, causing the volume of the variable gas storage chamber 36 to expand, thereby squeezing the adjacent variable water storage chamber 37, and allowing the water in the variable water storage chamber 37 to enter the lower-level water supply system from the water outlet 11; when gas supply is needed, the electric control valve is opened, and the high-pressure gas in the high-pressure hydrogen cylinder 3 enters the lower-level gas supply system from the high-pressure gas flow channel 322 from the high-pressure gas duct 42.

[0044] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of this patent.
