[0006] The heating element is wound around the periphery of the heating channel. A notch is provided at one end of the furnace core. The water inlet connects to the beginning of the heating channel, and the end of the heating channel connects to the vaporization channel through the notch. The width of the heating channel gradually increases from the beginning to the end.

[0007] The vaporization channel includes a first channel and a second channel connected in sequence, with the first channel and the second channel distributed sequentially front and back. The heating channel is connected to the first channel, and the second channel is connected to the vaporization insulation channel. The width of the first channel is greater than the width of the second channel. The heating component is located on one side of the vaporization channel.

[0008] The heating channel is connected to the beginning of the first channel, the end of the first channel is connected to the beginning of the second channel, and the end of the second channel is connected to the vaporization insulation channel. The width of the beginning of the first channel gradually decreases to the end of the first channel, and the width of the beginning of the second channel gradually decreases to the end of the second channel.

[0009] The furnace core is provided with through holes, connecting ports and a first barrier rib on its side. The vaporization channel is connected to the vaporization insulation channel through the through holes, and the vaporization insulation channel is connected to the insulation channel through the connecting ports. The outer side of the first barrier rib abuts against the inner wall of the outer shell. The through holes are located on one side of the first barrier rib, and the connecting ports are located on the other side of the first barrier rib, so that the vaporization insulation channel is arranged around the periphery of the furnace core.

[0010] The outer ring of the furnace core is provided with a second barrier rib, the outer side of which abuts against the inner wall of the outer shell.

[0014] A steam cleaning machine designed for this purpose is characterized by including the aforementioned boiler.

[0015] This utility model boiler incorporates heating and vaporization channels within the furnace core. A vaporization and insulation channel is formed between the outer wall of the furnace core and the inner wall of the outer shell. Water enters the heating channel through the inlet and is first heated by heating components. The heating channel gradually widens, allowing the water to remain in the heating channel for a longer period, thus increasing the water temperature. The heated water then enters the vaporization channel to vaporize into steam. Here, the vaporization channel narrows, hindering the water flow and making it easier for the heated and pressurized water to vaporize, thereby improving vaporization efficiency. Most of the water vaporizes into steam within the vaporization channel, and then... Steam and a small amount of remaining water reach the vaporization and insulation channel. The remaining water absorbs heat from the outside of the furnace core and vaporizes. The heat from the outside of the furnace core keeps the steam warm, preventing it from liquefying and further improving vaporization efficiency. The steam then reaches the insulation channel and continues to absorb heat from the outside of the furnace core for insulation. Finally, the steam is discharged from the boiler through the steam outlet. This structure can greatly improve the steam conversion rate and increase the steam output of the boiler (up to 30 mL / min), thereby greatly reducing the amount of water coming out of the steam outlet, making the steam outlet virtually free of water spray, and improving the atomization effect.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-10 This boiler includes a boiler body 1, which includes a furnace core 2 and an outer shell 3. The furnace core 2 is located inside the outer shell 3. The boiler body 1 has a water inlet 4 at the rear end and a steam outlet 5 at the front end. The furnace core 2 is equipped with a heating element 6. The furnace core 2 has a heating channel 7 for heating water and a vaporization channel 8 for vaporizing water. The water inlet 4, heating channel 7, and vaporization channel 8 are connected in sequence and are arranged in a meandering manner. The outer wall of the furnace core 2 and the inner wall of the outer shell 3 form a vaporization insulation channel 9 for continuous water vaporization and steam insulation and pressure maintenance, and an insulation channel 10 for steam insulation and pressure maintenance. The vaporization insulation channel 9 and insulation channel 10 are arranged around the furnace core 2. The vaporization channel 8, vaporization insulation channel 9, insulation channel 10, and steam outlet 5 are connected in sequence.

[0028] Heating element 6 is wound around the periphery of heating channel 7 to increase the contact area between furnace core 2 and heating element 6, thereby improving heating efficiency. Furnace core 2 has a notch 11 at the front end, and water inlet 4 connects to the beginning of heating channel 7. The end of heating channel 7 connects to vaporization channel 8 through notch 11. Hot water from heating channel 7 enters vaporization channel 8 through notch 11. The width of heating channel 7 gradually increases from the beginning to the end, which can reduce the water flow speed, allowing the water to stay in heating channel 7 for a longer time, and also increasing the contact area between water and furnace core 2, thus fully exchanging heat and increasing water temperature, making the water easier to vaporize. The water in heating channel 7 mainly absorbs heat from inside furnace core 2.

[0029] The vaporization channel 8 includes a first channel 12 and a second channel 13 connected in sequence. The first channel 12 and the second channel 13 are distributed one after the other. The heating channel 7 is connected to the first channel 12, and the second channel 13 is connected to the vaporization insulation channel 9. The width of the first channel 12 is greater than the width of the second channel 13. The heating component 6 is located on one side of the vaporization channel 8 and can continue to heat the water and steam in the vaporization channel 8, thereby vaporizing the water. The second channel 13 is narrower. When the water reaches the second channel 13, it will be pressurized. Most of the high-temperature and high-pressure water is vaporized in the second channel 13, while the water in the first channel 12 will be hindered by the steam in the second channel 13, resulting in a slower flow rate and a longer heating time. Moreover, the water is heated and pressurized, and some of the water will turn into steam, thereby improving the vaporization efficiency.

[0030] Heating channel 7 connects to the beginning of first channel 12, the end of first channel 12 connects to the beginning of second channel 13, and the end of second channel 13 connects to vaporization insulation channel 9. The width of first channel 12 gradually decreases from the beginning to the end, and the width of second channel 13 gradually decreases from the beginning to the end. This structure makes the water under pressure gradually increase, thus making it easier to turn into steam. The water in vaporization channel 8 mainly absorbs heat from inside furnace core 2.

[0031] The furnace core 2 has a through hole 14, a connecting port 15, and a first barrier rib 16 on its side. The vaporization channel 8 (second channel 13) is connected to the vaporization insulation channel 9 through the through hole 14. The vaporization insulation channel 9 is connected to the insulation channel 10 through the connecting port 15. The outer side of the first barrier rib 16 abuts against the inner wall of the outer shell 3. The through hole 14 is located on one side of the first barrier rib 16, and the connecting port 15 is located on the other side of the first barrier rib 16. The connecting port 15 is set close to the first barrier rib 16 so that the vaporization insulation channel 9 is arranged around the periphery of the furnace core 2. The water and steam entering the vaporization insulation channel 9 will circle the furnace core 2 before reaching the connecting port 15. The water and steam can fully absorb the heat outside the furnace core 2, so that the water will be basically vaporized, while the steam will be fully insulated, thereby improving the vaporization efficiency. The water and steam in the vaporization insulation channel 9 mainly absorb the heat from the rear end of the furnace core 2.

[0032] The outer ring of the furnace core 2 is provided with a second barrier rib 17. The outer side of the second barrier rib 17 abuts against the inner wall of the outer shell 3. The vaporization heat preservation channel 9 and the heat preservation channel 10 are separated from each other by the second barrier rib 17. The connecting port 15 is located on one side of the second barrier rib 17. The heat preservation channel 10 and the vaporization heat preservation channel 9 are distributed in sequence front and back.

[0033] The furnace core 2 has a protruding V-shaped guide rib 18 at its front end, and the outer shell 3 has a V-shaped barrier guide rib 19 at its front end. The guide rib 18 and the barrier guide rib 19 are interlocked, forming a heat-insulating channel 10 between the guide rib 18, the barrier guide rib 19, and the inner wall of the outer shell 3. The furnace core 2 has a flow channel 20 on its side, and the connecting port 15 connects to the heat-insulating channel 10 through the flow channel 20. The flow channel 20 passes through one side of the second barrier rib 17 to form the connecting port 15. The steam vaporizing the heat-insulating channel 9 passes through the connecting port 15 and the flow channel 20 to reach the heat-insulating channel 10. The flow channel 20 is located on one side of the guide rib 18 and the barrier guide rib 19, and the steam outlet 5 is located on the other side of the guide rib 18 and the barrier guide rib 19, dividing the heat-insulating channel 10 into a third channel 21 and a fourth channel 22 distributed vertically. The flow channel 20 passes through the third channel 21 and the fourth channel 22 respectively. 22 connects to steam outlet 5; the steam coming out of flow channel 20 will enter the third channel 21 and the fourth channel 22 respectively, and then the steam in the third channel 21 and the fourth channel 22 will flow to steam outlet 5 respectively, converge at steam outlet 5, and then be discharged from the boiler body 1 through steam outlet 5; the third channel 21 is shaped like one loop of the figure eight, and the fourth channel 22 is another loop of the figure eight, so that the steam has to go around once to reach steam outlet 5, extending the steam flow path, and the steam can fully absorb the heat outside the furnace core 2, improve the heat preservation effect, and prevent steam liquefaction; the steam in the heat preservation channel 10 mainly absorbs the heat at the front end of the furnace core 2; in summary, the heat inside the furnace core 2, outside the furnace core 2, rear end of the furnace core 2, and front end of the furnace core 2 are basically absorbed by water and steam, and the heat of the entire furnace core 2 can be basically utilized, thereby improving the steam conversion rate.

[0034] The guide rib 18 is provided with a plug groove 23, and the barrier guide rib 19 is provided with a plug part 24. The plug part 24 and the plug groove 23 are plugged into each other to connect the guide rib 18 and the barrier guide rib 19. The heat preservation channel 10 is separated from the heating channel 7 and the vaporization channel 8 (first channel 12) by the barrier guide rib 19 to prevent water in the heating channel 7 and the vaporization channel 8 from entering the heat preservation channel 10, and also to prevent steam in the heat preservation channel 10 from entering the heating channel 7 and the vaporization channel 8.

[0035] The flow guide rib 19 is provided with a first insertion hole 25 and a second insertion hole 26. The front end of the heating channel 7 is inserted into the first insertion hole 25, and the front end of the first channel 12 is inserted into the second insertion hole 26.

[0036] The flow guide rib 19 has a positioning part 27 in the middle, and the flow guide rib 18 has a positioning groove 28 in the middle. The positioning part 27 is inserted into the positioning groove 28 so that the outer shell 3 and the furnace core 2 are positioned relative to each other. The outer shell 3 and the furnace core 2 are connected by screws. The notch 11 is set in the middle of the flow guide rib 18, and the positioning grooves 28 are respectively set on both sides of the notch 11.

[0037] The outer shell 3 has a conical inner cavity 29, the furnace core 2 is conical and is inserted into the inner cavity 29; the water inlet 4 is located at the rear end of the furnace core 2, and the steam outlet 5 is located at the front end of the outer shell 3.

[0038] The heating element 6 is a heating tube and is spiral-shaped, which increases the contact area between the furnace core 2 and the heating element 6. The furnace core 2 and the heating element 6 are integrally die-cast to improve the heat transfer efficiency and allow the heat to be fully transferred to the furnace core 2. The periphery of the heating element 6 is close to the vaporization insulation channel 9 and the insulation channel 10, so that the heat can fully reach the vaporization insulation channel 9 and the insulation channel 10.

[0039] This steam cleaner includes a boiler, a connecting pipe 30, a floor brush 31, and a housing 32. The housing 32 contains an electrical cavity 33 and a receiving cavity 34. The boiler body 1 is located within the electrical cavity 33. A water tank 35 is located within the receiving cavity 34. One end of the water tank 35 has a water outlet connector 36, which is connected to a water inlet 4 via a water pipe. A water pump is installed inside the water tank 35, which pumps water from the tank to the heating channel 7. The housing 32 is connected to the floor brush 31 via the connecting pipe 30. The floor brush 31 has a steam port. The steam outlet 5, the connecting pipe 30, and the steam port are sequentially connected.
