[0030] A preferred embodiment provided by the present utility model will be specifically described with reference to the accompanying drawings.

[0031] Figures 1 to 13, which is a preferred embodiment of a steam generator for quickly generating steam provided by the present utility model. The steam generator includes a water storage pipe 10 and a plurality of heating pipes 20. The bottom port of the water storage pipe 10 and the inlet openings of each heating pipe 20 are communicated with a water passing cavity 61. The water passing cavity 61 is communicated with a water passing port 30. The outlet openings of each heating pipe are communicated with a steam outlet cavity 71. The steam outlet cavity 71 is communicated with a steam outlet 40. The steam outlet cavity 71 is also communicated with a return port 711 for returning the water carried out during the rising process of the steam to the water storage pipe 10. In this way, after the water entering from the water passing port 30 enters the water passing cavity 61, it then enters the water storage pipe 10 and the plurality of heating pipes 20 respectively. The heating pipes 20 are used to quickly heat only the water in the heating pipes, reducing the amount of water to be heated, quickly generating steam by heating, providing heat energy, and meeting the existing demand for instant steam generation; during the heating process of the heating pipes 20, when the external stops supplying water to the water passing port 30, the water stored in the water storage pipe 10 will automatically supply water to each heating pipe 20; the water carried out during the steam discharge process can be returned to the water storage pipe 10 for recycling, saving resources.

[0032] The heating pipe 20 is an electrothermal film heating pipe, and the electrothermal film is a microcrystalline glass electrothermal film. Microcrystalline glass electrothermal film (microcrystalline glass heating plate), scientific name "tin dioxide thin film", is a doped semiconductor nano-conductive thin film material formed on the surface of high-temperature resistant insulating substrates such as glass, mica, and ceramics by thin film processes such as chemical vapor deposition, spray pyrolysis, ion sputtering, and evaporation. Microcrystalline glass electrothermal film, also known as inorganic electrothermal film, transparent electrothermal film, etc., has high hardness, strong bonding with the carrier, stable high-temperature performance, can work at a relatively high temperature of 500 °C, has good oxidation resistance, chemical corrosion resistance, and good resistance stability, and has main characteristics such as energy saving, light weight, long life, no open flame, and small starting current. Positive and negative electrodes are provided on the electrothermal film of the heating pipe 20, and energized wires electrically connected thereto are respectively provided on the positive and negative electrodes. Copper sheets are provided on the electrothermal film, and the energized wires are electrically connected to the electrothermal film through the copper sheets.

[0033] A water level sensor 50 for sensing the water level is further provided in the water storage pipe 10. The water level sensor 50 is connected to an external control module to control the on-off of the water passing port 30. The water level sensor 50 is arranged in the water storage pipe 10 through a support rod 51. The water level sensor 50 includes an upper water level sensor 501 and a lower water level sensor 502. The upper water level sensor 501 is above the lower water level sensor 502. When the water level reaches the position of the upper water level sensor 501, the water passing port 30 can stop supplying water; when the water level reaches the position of the lower water level sensor 502, the water passing port 30 can continue to supply water.

[0034] A baffle 712 is further provided in the steam outlet chamber 71. A communication port 7121 communicating with the steam outlet 40 is provided on the baffle 712. The steam discharged from the outlet ends of the heating tubes 20 will carry water. When the steam encounters the baffle 712, the water is separated from the steam. The water will adhere to the baffle 712, and the steam passes through the communication port 7121, enters the steam outlet chamber 71, and finally is discharged from the steam outlet 40. When the water adhering to the baffle 712 accumulates to a certain amount, it will flow back to the water storage pipe 10 through the return port 711, forming a primary water cycle. It should be noted that during the discharge process of the steam, a part of the steam will condense when encountering the baffle 712 and the side wall of the steam outlet chamber 71 to form condensed water, and the condensed water will flow back to the water storage pipe 10 through the return port 711.

[0035] As a preferred embodiment, the bottom end of the water storage pipe 10 is communicated with a water passing chamber 60. A water passing cavity 61 is arranged in the water passing chamber 60. The bottom port of the water storage pipe 10 and the inlet openings of the heating tubes communicate with the water passing cavity 61 of the water passing chamber 60. In this way, the water flowing in through the water passing port 30 can first converge in the water passing cavity 61 and then be divided and flow into the water storage pipe 10 and each heating tube 20. The top end of the water storage pipe 10 is communicated with a steam outlet chamber 70. A steam outlet chamber 71 is arranged in the steam outlet chamber 70. The top port of the water storage pipe 10 and the outlet openings of the heating tubes communicate with the steam outlet chamber 71. In this way, the steam discharged from the outlet openings of the heating tubes 20 converges in the steam outlet chamber 71 and is then discharged from the steam outlet 40.

[0036] As another preferred embodiment, the inlet openings and outlet openings of each heating tube 20 are both communicated with the inner cavity of the water storage pipe 10. The inner cavity of the water storage pipe 10 is a water storage cavity 61 and a steam outlet chamber 71, and the steam outlet chamber 71 is above the water storage cavity 61. That is, the inner cavity of the water storage pipe 10 is directly communicated with the inlet openings and outlet openings of each heating tube 20. The top and bottom of the water storage pipe 10 are respectively communicated with the steam outlet 40 and the water passing port 30. The water entering from the water passing port 30 directly enters the lower part of the inner cavity of the water storage pipe 10, that is, the water storage cavity 61, and then is divided and flows into each heating tube 20. The steam generated by heating each heating tube directly enters the upper part of the inner cavity of the water storage pipe 10, that is, the steam outlet chamber 71, and then is discharged from the steam outlet 40.

[0037] The bottom end and the top end of the heating tube 20 are respectively butted with an upper sealing joint seat 21 and a lower sealing joint seat 22. A through port 201 and a placement groove 203 for placing the end of the heating tube are provided in both the upper sealing joint seat 21 and the lower sealing joint seat 22, so as to ensure the sealing of both ends of the heating tube 20 and prevent water from leaking out. The upper sealing joint seat 21 and the lower sealing joint seat 22 are both silicone sealing seats. A retaining edge 211 is further formed on the upper sealing joint seat 21. When the water carried by the rising steam encounters the retaining edge 211, it will converge on the retaining edge 211. When it reaches a certain amount, it will flow back into the heating tube 20.

[0038] The heating pipe 20 is provided with an inner pipe 23. A water passage 2301 is formed between the inner pipe 23 and the heating pipe 20. An inlet 231 and an outlet 232 communicating with the water passage 2301 are provided on the side wall of the inner pipe 23. For the water entering the heating pipe 20, part of the water enters the water passage 2301 from the inlet 231, and the other part is inside the inner pipe 23. When the heating pipe 20 is heated, the water in the water passage 2301 is heated first, reducing the amount of water to be heated. The water in the inner pipe 23 can replenish the water in the water passage 2301 at any time.

[0039] To position the inner pipe 20, bosses 202 for sealing and docking with the ends of the inner pipe 23 are formed on both the upper sealing joint seat 21 and the lower sealing joint seat 22, so that the inner pipe 23 is in a vertical state in the heating pipe 20. The retaining edge 211 formed on the upper sealing joint seat 21 corresponds to the outlet 232 of the inner pipe. A gap is left between the retaining edge 211 and the inner wall of the inner pipe 20. When the water vapor generated by heating the water in the water passage 231 is discharged from the outlet 232, the water carried by the steam will adhere to the retaining edge 211. The steam passes through the through-port 201, enters the steam outlet cavity 71, and finally is discharged from the steam outlet 40. The water on the retaining edge 211 will flow back into the inner pipe 23, forming another water cycle.

[0040] The water passage cavity 61 is communicated with a lower pressure balance pipe joint 80, and the steam outlet cavity 71 is communicated with an upper pressure balance pipe joint 90. By using the lower pressure balance pipe joint 80 and the upper pressure balance pipe joint 90, an external pressure balance pipe is connected, which is convenient for monitoring the internal pressure. And by using the lower pressure balance pipe joint 80 and the upper pressure balance pipe joint 90, it can also be connected to the downstream module and the upstream module to form a parallel pipeline.

[0041] In addition, according to the design requirements, the heating pipes 20 can be circumferentially distributed around the central axis of the water storage pipe 10, or the heating pipes 20 can be arranged in a straight line.

[0042] Figures 1 to 7, which is the first embodiment of a steam generator for quickly generating steam provided by the present utility model. In this embodiment, each heating pipe 20 is evenly distributed in a circle around the central axis of the water storage pipe 10. An inlet and outlet water chamber 60 is provided at the bottom end of the water storage pipe 10. A water passage chamber 61 is arranged in the water passage chamber 60. A water inlet 30 is provided at the bottom of the inlet and outlet water chamber 60. A steam outlet chamber 70 is provided at the top end of the water storage pipe 10. A steam passage chamber 71 is arranged in the steam outlet chamber 70. A steam outlet 40 is provided at the top of the steam outlet chamber 70. The bottom port of the water storage pipe 10, the inlet openings of each heating pipe, and the upper pressure balance joint 90 are directly communicated with the water passage chamber 61. The top port of the water storage pipe 10, the outlet openings of each heating pipe 20, and the lower pressure balance pipe joint 80 are directly communicated with the steam passage chamber 71. An inner pipe 23 is arranged in each heating pipe 20. Upper and lower sealing joint seats 21 and 22 are respectively arranged at the top and bottom ends of the heating pipe 20 and the inner pipe 23. A baffle 712 is arranged in the steam passage chamber 71. The outlet opening of the heating pipe 20, the outlet 232 of the inner pipe 23, the gap between the eaves 211 of the upper sealing joint seat 21 and the inner pipe 23, the through port 201 of the upper sealing joint seat 21, the steam passage chamber 71, the communication port 7121 of the baffle 712, and the steam outlet 40 form a steam outlet passage. The return port 711 between the steam passage chamber 71 and the water storage pipe 10 is the opening provided at the top of the water storage pipe 10. A protective shell 100 is arranged between the inlet and outlet water chamber 60 and the steam outlet chamber 70. An installation bracket is arranged on one side of the protective shell 100.

[0043] As Figure 7 shown, the heating process is specifically as follows: (1) The water flowing in through the water inlet 30 can first converge in the water passage chamber 61 and then be divided and flow into the water storage pipe 10 and each heating pipe 20; (2) For the water entering from the inlet opening of the heating pipe 20, part of it enters the water passage 2301 from the inlet 231 of the inner pipe 23, and the other part is inside the inner pipe 23. When the heating pipe 20 is heating, the water in the water passage 2301 is heated and can be quickly heated to generate steam, and the steam flows out from the outlet 232 of the inner pipe 23; (3) The steam flowing out from the outlet 232 of the inner pipe 23 passes through the eaves 211 of the upper sealing joint seat 21, and the water carried in the steam adheres to the eaves 211 and converges,

[0044] As for the water formed after a part of the steam condenses when encountering the baffle 211, it will flow back into the inner pipe 23 to form the first water cycle. Another part of the steam bypasses the baffle 211 and is discharged into the steam outlet chamber 71 through the through-port 201 of the upper sealing joint seat 21; (4) The steam entering the steam outlet chamber 71 encounters the baffle 712, and the water carried in the steam is separated from the steam. The water will adhere to the baffle 712, and the steam passes through the communication port 7121 and enters the steam outlet chamber 71, and finally is discharged from the steam outlet 40; when the water adhering to the baffle 712 accumulates to a certain amount, it will flow back into the water storage pipe 10 through the return port 711. The water formed after the steam condenses in the steam outlet chamber 71 will also flow back into the water storage pipe 10 to form the second water cycle; (5) When the water level in the water storage pipe 10 reaches the position of the upper water level sensor 501, the water supply port 30 can stop supplying water, and the water stored in the water storage pipe 10 will automatically supply water to each heating pipe 20; when the water level in the water storage pipe 10 reaches the position of the lower water level sensor 502, the water supply port 30 can continue to supply water.

When the heating pipe 20 is electrified for heating, the water in the water passage 2301 is heated and rapidly raises the temperature to generate steam, and the steam flows out from the outlet 232 of the inner pipe 23; (3) The steam flowing out from the outlet 232 of the inner pipe 23 passes through the eaves 211 of the upper sealing joint seat 21.
