DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0031] Reference Figures 1-6, a water dispenser expansion water box, including a water tank 5, the interior of the water tank 5 is fixed with a heating wire 13 by bolts, the heating wire 13 is connected to an external power supply through a wire, so that the heating wire 13 heats the water in the water tank 5, the bottom of the water tank 5 is provided with a bottom plate 12, two fixing components are provided between the bottom plate 12 and the water tank 5, the top outer wall of the water tank 5 is fixed with two support frames 4 by bolts, the top of the two support frames 4 is fixed with an expansion water box body 3 by bolts, the top of the expansion water box body 3 is provided with an expansion water box cover 2, the expansion water box cover 2 and the expansion water box body 3 are fixed by a connecting component, the bottom of the expansion water box body 3 is fixed with a liquid outlet pipe 21 by bolts, the top of the liquid outlet pipe 21 is provided with a through hole 29, the bottom of the expansion water box body 3 is provided with a connecting port, and the connecting port is connected to the through hole 29, the top of the connecting port is connected and fixed with a connecting shell 25, the connecting shell 25 contains a float 26, and the float 26 can block the through hole 29. The top of the expansion water box cover 2 is connected to and fixed with an exhaust pipe 1. During the heating process of the water tank 5, the water level in the water tank 5 expands, and water and water vapor enter the expansion water box body 3 through the second liquid inlet pipe 28 and the through hole 29. At this time, the water vapor impacts the float 26, and the float 26 interacts with the water vapor under the action of its own weight. The water vapor impacts the connecting shell 25, and the water sinks under the action of its own gravity, and the hot gas rises. In this process, water and gas are separated, and the water is stored in the expansion water box body 3. The separated gas is discharged by the exhaust pipe 1. A water tank is provided on one side of the connecting shell 25. The bottom of the liquid outlet pipe 21 is connected to and fixed with a second liquid inlet pipe 28, and the second liquid inlet pipe 28 is connected and fixed to the water tank 5. A solenoid valve 22 is fixed at one end of the liquid outlet pipe 21, and the solenoid valve 22 is connected to the external faucet through an external connecting pipe.

[0032] In particular, the fixing assembly includes a fixing frame 8, which is threaded with a screw rod 9, one end of which is rotatably connected to the first wedge block 6, and the top of the bottom plate 12 is fixed with a second wedge block 11 by bolts. The second wedge block 11 and one side of the first wedge block 6 are both provided with inclined surfaces 10, and the inclined surface 10 on the first wedge block 6 contacts the inclined surface 10 on the second wedge block 11. When it is necessary to disassemble the bottom plate 12, the screw rod 9 is rotated to separate the inclined surface 10 on the first wedge block 6 from the inclined surface 10 on the second wedge block 11. At this time, the bottom plate 12 loses its extrusion support, and the staff pulls the bottom plate 12 downward to separate it from the water tank 5. Two guide rods 7 are slidably connected to the fixing frame 8, and the guide rod 7 is fixed to the first wedge block 6. The screw rod 9 is located in the middle position between the two guide rods 7, and the guide rod 7 can guide the first wedge block 6.

[0033] The cam 32 is screwed to the bottom of the cam 32 and the cam 33 is screwed to the top of the cam 32.

[0034] In the present invention, elastic sheets 19 are welded to both sides of the expansion water box cover 2, and a first protrusion 18 is integrally formed at the bottom end of the elastic sheet 19. Second protrusions 20 are welded to the outer walls of both sides of the expansion water box body 3, and the first protrusions 18 are against the bottoms of the second protrusions 20. Through the cooperation of the first protrusions 18 and the second protrusions 20, the elastic sheet 19 assists in fixing the expansion water box cover 2 and the expansion water box body 3.

[0035] One end of the liquid outlet pipe 21 is sealed with an expansion water box plug 27. The expansion water box plug 27 is made of food-grade silicone and is sleeved on the liquid outlet pipe 21 through an interference fit. A first water inlet is opened on one side of the water tank 5. The first water inlet is connected to and fixed with a first water inlet pipe 17. An electric valve can be connected to the first water inlet pipe 17 to control the water inlet situation of the first water inlet pipe 17. A retaining frame 16 is fixed to the inner wall of the water tank 5 near the first water inlet by bolts. A gap is left between the vertical plate part at the bottom of the retaining frame 16 and the first water inlet. The retaining frame 16 can block the water entering the water tank 5 through the first water inlet pipe 17 to prevent the water flow from directly impacting the devices inside the water tank 5.

[0036] The circumferential inner wall of the water tank 5 is provided with a fixing ring 15 by bolts, and the circumferential outer wall of the bottom plate 12 is bonded with a sealing ring 14, and the sealing ring 14 is in contact with the fixing ring 15. The cooperation of the sealing ring 14 and the fixing ring 15 makes the connection between the water tank 5 and the bottom plate 12 tighter. During the heating process, the water vapor in the water tank 5 is discharged into the expansion water box body 3, and the gas is discharged from the exhaust pipe 1 through the water vapor separation function of the expansion water box body 3. The water is stored in the expansion water box body 3. When taking water, the water flow absorbs the water inside the expansion water box body 3. This cyclic reciprocating operation can effectively solve the problems of steam spraying from the water outlet, skewed water outlet and expansion and deformation of the hot water tank, thereby ensuring the service life of the hot water tank and a good operating experience.

[0037] The working principle of this embodiment is as follows: the heating wire 13 is connected to an external power source via a wire, so that the heating wire 13 heats the water in the water tank 5. During the heating process, the water level in the water tank 5 expands, and water and water vapor enter the expansion water box body 3 through the second liquid inlet pipe 28 and the through hole 29. At this time, the water vapor impacts the float 26. The float 26 interacts with the water vapor under the action of its own weight. The water vapor impacts the connecting shell 25. The water sinks under the action of its own gravity, while the hot gas rises. In this process, water and gas are separated. The water is stored in the expansion water box body 3, and the separated gas is discharged through the exhaust pipe 1.

[0038] When the user draws water, the solenoid valve 22 and the electric valve on the first water inlet pipe 17 are opened at the same time, and hot water rushes out from the through hole 29 on the expansion water cartridge 3. At this time, a certain negative pressure is generated to suck the water in the expansion water cartridge 3 out until the float 26 drops to seal the through hole 29, while preventing external air from entering the water tank 5 and affecting the water flow, so that hot water flows out from the faucet outlet. When the user stops drawing water, the solenoid valve 22 and the first water inlet pipe 17 are closed at the same time.

[0039] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device that performs control such as a computer.
