[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0035] Integrated tank structure, used in sparkling water machines, such as Figure 1-7 As shown, it includes: a cold water tank 01 and a sparkling water tank 02; the sparkling water tank 02 is used to mix cold water and carbon dioxide in the sparkling water tank 02 to prepare sparkling water.

[0036] The cold water tank 01 includes a cold water tank body 100 and a cold water tank lid 200; the sparkling water tank 02 includes a sparkling water tank body 300 and a sparkling water tank lid 400. The sparkling water tank body 300 has an outwardly extending support edge 310, and the support edge 310 is provided with a locking tongue 311; the sparkling water tank lid 400 is provided with a locking part 410 with a locking groove 411, and when the sparkling water tank body 300 and the sparkling water tank lid 400 are assembled, the locking tongue 311 rotates and engages with the locking groove 411; the sparkling water tank lid 400 is provided with an upper screw hole 420, and the cold water tank lid 200 is provided with a lower screw hole 220, the upper screw hole 420 and the lower screw hole 220 correspond to each other and are locked together by screws 500.

[0037] In this technical solution, the sparkling water tank body 300 and the sparkling water tank lid 400 are combined by a screw fastener, and the sparkling water tank lid 400 and the cold water tank lid 200 are combined by a screw fastener. Compared with the traditional technology where the sparkling water tank body 300 and the sparkling water tank lid 400, as well as the sparkling water tank lid 400 and the cold water tank lid 200 are combined by screw fasteners, the assembly is faster, the number of screws can be reduced by half, and the locking force of the fixing screws can be reduced.

[0038] Specifically, the support edge 310 and the bubble water tank 300 are integrally formed, and the locking tongue 311 protrudes radially outward along the support edge 310; as Figure 1As shown, during installation, the sparkling water can lid 400 is installed from top to bottom into the opening at the top of the sparkling water can 300. Then, the can lid 400 is kept stationary while the sparkling water can 300 is... Figure 1 Rotating in the direction indicated by the middle arrow, the locking tongue 311 is screwed into the locking groove 411 for limiting, thus limiting the assembly between the sparkling water tank body 300 and the sparkling water tank lid 400. After assembly, it is as follows: Figure 2 As shown.

[0039] Continue as Figure 1 As shown, the right end of the locking groove 411 forms a groove inlet 411a, and the left end of the locking groove 411 is closed to prevent the lock 311 from being unscrewed out of the locking groove 411 when the bubble water tank 300 rotates excessively during locking.

[0040] Continue as Figure 1 As shown, the sparkling water can lid 400 is partially inserted into the sparkling water can body 300. A sealing ring groove 430 is provided at the position where the sparkling water can lid 400 is inserted into the sparkling water can body 300. A sealing ring is installed in the sealing ring groove 430. After the sparkling water can lid 400 and the sparkling water can body 300 are assembled, the opening of the sparkling water can body 300 is sealed by the sealing ring to prevent air and water leakage.

[0041] like Figure 8 As shown, the sealing groove 430 in this technical solution has two rings, and correspondingly there are two sealing rings, resulting in better sealing performance.

[0042] Furthermore, such as Figure 1 and Figure 3 As shown, the locking part 410 is disposed on the lower surface of the sparkling water tank lid 400 and protrudes toward the upper surface of the cold water tank lid 200; the cold water tank lid 200 is provided with a clearance hole 210; when the sparkling water tank lid 400 is installed on the upper surface of the cold water tank lid 200, the locking part 410 is embedded in the clearance hole 210.

[0043] Furthermore, the locking part 410 and the upper screw hole 420 are alternately arranged on the sparkling water tank lid 400; the clearance hole 210 and the lower screw hole 220 are alternately arranged on the cold water tank lid 200.

[0044] Furthermore, the cold water tank cover 200 is provided with a through hole 201, and the clearance hole 210 and the lower screw hole 220 are distributed around the through hole 201.

[0045] like Figure 1 As shown, the locking part 410 and the upper screw hole 420 are arranged approximately circumferentially and alternately on the sparkling water tank lid 400. Similarly, the clearance hole 210 and the lower screw hole 220 are arranged approximately circularly and alternately on the cold water tank lid 200. Figure 4As shown, after the sparkling water tank 02 is assembled, the sparkling water tank 02 is passed through the through hole 201 from top to bottom. The sparkling water tank lid 400 is supported on the cold water tank lid 200. The sparkling water tank lid 400 and the cold water tank lid 200 are locked together by screws 500.

[0046] like Figure 5 As shown, the upper surface of the sparkling water can lid 400 is also provided with a nut 510 with a washer, which is used in conjunction with the screw 500.

[0047] like Figure 6 As shown, after the sparkling water tank lid 400 and the cold water tank lid 200 are assembled, the locking part 410 and the upper screw hole 420 are alternately set. During transportation, due to vibration, the sparkling water tank body 300 rotates in the opposite direction to the sparkling water tank lid 400. Due to the obstruction of the screw 500, the locking tongue 311 of the sparkling water tank body 300 cannot be completely unscrewed from the locking groove 411, and the sparkling water tank body 300 and the sparkling water tank lid 400 will not separate.

[0048] like Figure 1 , Figure 4 and Figure 7 As shown, during assembly, the sparkling water tank body 300 and sparkling water tank lid 400 are assembled first, then the sparkling water tank 02 is assembled with the cold water tank lid 200, and finally the cold water tank body 100 and cold water tank lid 200 are assembled.

[0049] like Figure 8 As shown, a sealing ring is provided in the through hole 201 of the cold water tank cover 200, so that the sparkling water tank 02 can be sealed when installed in the cold water tank cover 200, and a sealing ring is provided between the cold water tank cover 200 and the cold water tank body 100 to achieve sealing.

[0050] Furthermore, the cold water tank body 100 and the cold water tank cover 200 are assembled by means of screws and / or by means of snaps.

[0051] Specifically, such as Figure 7-8 As shown, the cold water tank body 100 and the cold water tank cover 200 are assembled by means of screws and by means of snaps. During assembly, the cold water tank body 100 and the cold water tank cover 200 are initially positioned by means of snaps, and then further tightened by means of screws, so that the assembly is stable.

[0052] Furthermore, such as Figure 7-8 As shown, the sparkling water tank lid 400 is provided with a carbon dioxide inlet 402, a sparkling water outlet 403, a cold water inlet 404, and a pressure relief valve 405 that are connected to the sparkling water tank body 300; the cold water tank lid 200 is provided with an air vent 202, a tap water inlet 203, and a return water inlet 205, and the bottom of the cold water tank body 100 is provided with a cold water outlet 204.

[0053] like Figure 7 and Figure 8 As shown, tap water enters the cold water tank 01 through the tap water inlet 203 for cooling. The cooled tap water flows out from the cold water outlet 204 at the bottom of the cold water tank 100 and enters the sparkling water tank 02 through the cold water inlet 404. Carbon dioxide enters the sparkling water tank 02 through the carbon dioxide inlet 402. The carbon dioxide and cold water mix in the sparkling water tank 02 to form delicious sparkling water. Finally, the sparkling water flows out from the sparkling water outlet 403 for users to drink. During this process, when tap water is first injected into the cold water tank 01, the air in the cold water tank 01 is discharged through the atmospheric outlet 202.

[0054] Furthermore, such as Figure 9 As shown, the cold water tank 100 is provided with an insulation layer 600, which can effectively reduce the loss of cooling capacity.

[0055] Specifically, such as Figure 8-9 As shown, the insulation layer 600 is preferably a foam insulation layer, and the cold water tank body 100 is covered with the insulation layer 600, and the cold water tank lid 200 is also covered with an insulation layer.

[0056] Furthermore, such as Figure 7 As shown, an evaporator 700 is provided between the cold water tank 100 and the sparkling water tank 300. The evaporator 700 is coiled around the sparkling water tank 300 inside the cold water tank 100. The integrated tank structure of this technology is applied in a sparkling water machine. The evaporator 700 is one of the components of the refrigeration system in the sparkling water machine. The evaporator 700 is connected to other components of the refrigeration system in the sparkling water machine. During operation, it cools the water in the cold water tank 01. The refrigeration principle of the evaporator 700 is existing technology and will not be described in detail here.

[0057] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
