It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0028] like Figure 1 , Figure 2 and Figure 10 As shown, a kettle with an integrated flow channel plate includes an upper kettle body 1, a lower kettle body 2, and a flow channel plate 3. The lower kettle body 2 is welded to the flow channel plate 3 (hot plate welding; both the lower kettle body 2 and the flow channel plate 3 are made of polymer materials; the upper part of the flow channel plate 3 has a portion of the flow channel structure, and the bottom of the lower kettle body 2 has another portion of the flow channel corresponding to the upper flow channel of the flow channel plate 3; the hot plate melts 1.5mm of the connecting surface between the lower kettle body 2 and the flow channel plate 3, and then the two products are quickly pressed together for welding to form a complete flow channel). The lower kettle body 2 is an elliptical cylinder with an open top. The upper vessel 1 has a shape corresponding to the lower vessel 2. The lower vessel 2 has an opening at the bottom. The upper vessel 1 and the lower vessel 2 are welded together (hot plate welding; the corresponding chambers between the upper vessel 1 and the lower vessel 2 are joined by welding the ribs of the chambers. The hot plate melts the connecting surfaces of the upper vessel 1 and the lower vessel 2 by 1.5mm, and then the two products are quickly pressed together for welding to form a complete chamber). After welding, the upper vessel 1 and the lower vessel 2 are used to contain liquid. The outer wall of the upper vessel 1 is marked with the highest liquid level, and the outer wall of the lower vessel 2 is marked with the lowest liquid level.

[0029] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the flow channel plate 3 includes a first water pump seat 31, a second water pump seat 32, and an intermediate plate 33. The first water pump seat 31 and the second water pump seat 32 are respectively located at both ends of the intermediate plate 33. The lower end face of the first water pump seat 31 is used to connect to an external water pump, and the lower end face of the second water pump seat 32 is used to connect to another external water pump. The intermediate plate 33 is used to connect to an external water valve. The intermediate plate 33 is provided with a first valve port 301, a second valve port 302, a third valve port 303, a fourth valve port 304, a fifth valve port 305, and a sixth valve port 306. The six valve ports are used to communicate with the external water valve. The six valve ports are distributed in two rows and three columns, which is compact and can save space. Each valve port is a square opening. The external water valve controls the opening and closing between different valve ports to form different flow directions. The first pump base 31 is equipped with a first pump inlet 52 and a sixth water pipe 46. The first pump inlet 52 is located at the top of the first pump base 31 and extends downwards. The sixth water pipe 46 is located tangentially to the first pump base 31. When a pump is installed on the first pump base 31, liquid enters the pump from the first pump inlet 52 and is then discharged from the sixth water pipe 46 under the action of the pump. The second pump base 32 is equipped with a second pump inlet 56 and a third water pipe 43. The second pump inlet 56 is located at the top of the second pump base 32 and extends downwards. The third water pipe 43 is located tangentially to the second pump base 32. When a pump is installed on the second pump base 32, liquid enters the pump from the second pump inlet 56 and is then discharged from the third water pipe 43 under the action of the pump. The arrangement of the two pump bases on both sides of the intermediate plate 33 makes the pump outlet structure (i.e., the sixth water pipe 46 and the third water pipe 43) short and straight, effectively reducing flow resistance.

[0030] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the lower pot body 2 is connected to a first water pipe 41, a fourth water pipe 44, and a fifth water pipe 45. The third valve port 303 is connected to the second water pump inlet 56. The sixth valve port 306 of the intermediate plate 33 is connected to the first water pump inlet 52. The first valve port 301 is connected to the first water pipe 41. The fourth valve port 304 is connected to the fourth water pipe 44. The fifth valve port 305 is connected to the fifth water pipe 45. The end of the intermediate plate 33 near the first water pump seat 31 is connected to a seventh water pipe 47, which is connected to the sixth valve port 306. The end of the intermediate plate 33 near the second water pump seat 32 is also connected to a second water pipe 42, and the second valve port 302 is connected to the second water pipe 42.

[0031] like Figure 3 , Figure 4 and Figure 5As shown, the flow channels connecting the two pump inlets (first pump inlet 52 and second pump inlet 56) of the intermediate plate 33 are short and gentle, which can effectively reduce flow resistance. The horizontal height of the first pump inlet 52 and the second pump inlet 56 is higher than the horizontal height of the six valve ports (301-306).

[0032] like Figure 6 , Figure 7 and Figure 8 As shown, the lower body 2 is provided with two parallel first ribs 71 and four second ribs 72 perpendicular to the first ribs 71. The four second ribs 72 are arranged at equal intervals. The two first ribs 71 are arranged horizontally, and the four second ribs 72 are arranged vertically. The two first ribs 71 and the four second ribs 72 divide the space inside the lower body 2 into multiple chambers, including the first chamber 21, the second chamber 22, the third chamber 23, the fourth chamber 24, the fifth chamber 25, the sixth chamber 26, the seventh chamber 27, the eighth chamber 28, the ninth chamber 29, the tenth chamber 210, the eleventh chamber 211, the twelfth chamber 212, the thirteenth chamber 213, the fourteenth chamber 214, and the fifteenth chamber 215.

The first chamber 21 is connected to the tenth chamber 210 through the first through hole 61; the first chamber 21 is connected to the second chamber 22 through the second through hole 62; the second chamber 22 is connected to the third chamber 23 through the third through hole 63; the third chamber 23 is connected to the eighth chamber 28 through the fourth through hole 64; and the fourth chamber 24 is connected to the seventh chamber 27 through the fifth through hole 65. Chamber 24 is also connected to chamber 25 via the sixth through-hole 66. Chamber 25 is connected to chamber 26 via the seventh through-hole 67. Chamber 26 is connected to chamber 215 via the eighth through-hole 68. Chamber 28 is connected to chamber 213 via the eleventh through-hole 611. Chamber 29 is connected to chamber 212 via the twelfth through-hole 612. Chamber 210 is connected to chamber 211 via the fourteenth through-hole 614. Chamber 211 is connected to chamber 212 via the thirteenth through-hole 613. Chamber 213 is connected to chamber 214 via the tenth through-hole 610. Chamber 214 is connected to chamber 215 via the ninth through-hole 69. The bottoms of each chamber are connected by fourteen through-holes, which can prevent the liquid from shaking violently in the kettle and also allow the liquid inside the kettle to be replenished, providing time and space for gas-liquid separation.

[0033] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a first connecting port 51 is provided between the first water pump inlet 52 and the sixth valve port 306. An eleventh connecting port 501 is provided on the fourth water pipe 44 at the position corresponding to the first connecting port 51. The fourth water pipe 44 is connected to the seventh chamber 27 through the eleventh connecting port 501. The sixth valve port 306 is connected to the space inside the lower pot body 2 through the first connecting port 51 and the eleventh connecting port 501. Liquid enters the seventh chamber 27 inside the lower pot body 2 after passing through the first connecting port 51 and the eleventh connecting port 501 from the sixth valve port 306. The second water pump inlet 56 is connected to the third valve port 303 by a second connecting port 53, a third connecting port 54, and a fourth connecting port 55. The second connecting port 53 and the third connecting port 54 are connected to the third valve port 303, and the fourth connecting port 55 is connected to the second water pump inlet 56. The second water pump inlet 56 is connected to the third valve port 303. The lower vessel body 2 has a twelfth connecting port 503 corresponding to the second connecting port 53, a thirteenth connecting port 504 corresponding to the third connecting port 54, and a fourteenth connecting port 505 corresponding to the fourth connecting port 55. The second connecting port 53 and the third connecting port 54 are connected to the ninth chamber 29, and the fourth connecting port 55 is connected to the tenth chamber 210. Liquid flows from the third valve port 303 through the second connecting port 53. After the third connecting port 54, the twelfth connecting port 503 and the thirteenth connecting port 504 enter the ninth chamber 29 of the lower pot body 2. The twelfth connecting port 503 and the thirteenth connecting port 504 serve as degassing ports. The fourteenth connecting port 505 is located in the tenth chamber 210 and serves as the water supply port for the second water pump inlet 56. The fourteenth connecting port 505 is separate from the two degassing ports (the twelfth connecting port 503 and the thirteenth connecting port 504) and can only be connected through the twelfth through hole 612, the thirteenth through hole 613, the fourteenth through hole 614, the eleventh chamber 211 and the twelfth chamber 212, so as to fully remove the gas that enters the pot body through the degassing ports and prevent the gas from re-entering the system through the water supply port.

[0034] like Figure 1 , Figure 8 and Figure 9As shown, a pressure cap 11 is connected to the spout of the upper pot body 1. The upper pot body 1 contains two third ribs 13 and four fourth ribs 14. The third ribs 13 correspond to the first ribs 71 (the third ribs 13 are disconnected at the point corresponding to the spout), and the fourth ribs 14 correspond to the second ribs 72. Multiple upper chambers corresponding to the lower pot body 2 are formed on the upper pot body 1. Small holes are provided at the points corresponding to the upper chambers on the third ribs 13 and fourth ribs 14. The gas phase space at the top of the upper chambers in the upper pot body 1 is connected through these small holes to balance the pressure of each upper chamber. The gas collected in each upper chamber can flow to the spout through the small holes above and be discharged from the pot through the spout. The pressure cap 11 uses an existing cap with a bidirectional opening function. When the system pressure is too high, the pressure cap 11 will open in the forward direction to relieve the excessive internal pressure and maintain internal pressure stability. When the system pressure is too low, the pressure cap 11 will open in the reverse direction to compensate for the internal pressure and maintain internal pressure stability. The thirteenth chamber 213 of the lower pot body 2 is also provided with an overflow channel 615. The height of the overflow channel 615 is flush with the welding surface (welded to the overflow channel corresponding to the upper pot body). There is a through hole at the bottom. The overflowing liquid is guided in a directional manner through the overflow channel 615 to the through hole at the bottom to discharge the pot.

[0035] like Figure 10 As shown, the flow channel plate 3 is provided with a first threaded insert 38 and a second threaded insert 39. The first threaded insert 38 and the second threaded insert 39 are provided with internal threaded holes, which are pre-embedded in the flow channel plate 3 during injection molding. They can be connected to the two types of threaded inserts by corresponding bolts, thereby facilitating the connection of other external equipment to the flow channel plate 3.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
