Description

Technical Field

[0001] This invention relates to the field of electric steam generation technology, specifically to a range-extended electric steam generator. Background Technology

[0002] An electric steam generator is a boiler that automatically replenishes water, heats the water, and continuously generates steam, which can be used in canteens, dry cleaners, steam rooms, and other similar areas.

[0003] Currently, electric steam generators have certain drawbacks in actual use. Since electric steam generators are powered independently, they will stop if the external power supply is interrupted due to a sudden power outage. If the shutdown time is too long, the solution in the boiler will lose temperature until the overall temperature of the device drops. When restarting, more energy will be consumed. At the same time, the solution has low fluidity in the device cavity, so the solution area in contact with the heating tube is limited, which further reduces the efficiency of steam generation.

[0004] In view of this, a range-extended electric steam generator was designed to solve the above problems. Summary of the Invention

[0018] In a preferred embodiment, the present invention can be further configured such that the electric heating module is installed on the top of the load-bearing plate, and the four heating sections at the bottom of the electric heating module are respectively inserted into the interior of four heat-dissipating tubes.

[0019] In a preferred embodiment, the present invention can be further configured as follows: the range-extending power supply mechanism includes a chassis mounted on four studs by nuts, a generator fixedly mounted inside the chassis, a plug fixedly mounted on the drive shaft of the generator, an energy storage module electrically connected to the generator, a first wire connected to the energy storage module, a control module connected to the energy storage module via the first wire, a second wire connected to the bottom of the control module, a third wire connected to the top of the control module, and an electric heating module connected to the control module via the third wire.

[0021] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0022] 1. This invention installs an exhaust mechanism on the steam generating mechanism to enhance steam pressure and guide the orderly transmission of steam. The pressurized steam passes through the impeller and drives the impeller to rotate. The mechanical energy of the impeller rotation can be converted into backup energy for the range extender power supply mechanism by the generator. When the external power supply fails due to a sudden power outage, the energy storage module can quickly replace the external power supply to maintain the operation of the device, thereby ensuring that the device can continue to operate when the external power supply fails.

[0023] 2. This invention utilizes the rotation of the impeller and shaft within the exhaust mechanism to drive the high-frequency lifting and lowering of the sliding column and guide rod. The pull rod installed at the outer end of the guide rod drives the traction rod to extend in a regular manner. Finally, multiple evenly distributed stabilizing pads and extrusion heads can pressurize the solution in the storage chamber and draw it into the inner sleeve. Under pressurization, the drawn-in solution will ripple along the four heat-releasing pipes, increasing the flow rate of the rippled solution and thus effectively improving the efficiency of steam generation.

[0024] 3. In this invention, multiple stabilizing pads are evenly distributed in multiple vertical grooves of the column. When the multiple stabilizing pads extend laterally in a regular manner, the amplitude of the solution entering the inner sleeve will further increase. While the solution in the inner sleeve increases its fluidity through forced agitation, the agitated solution will compress the inner sleeve cavity and further compress the steam, thereby increasing the speed at which the steam rises. Finally, the pressure of the steam after convergence will be enhanced, thus effectively ensuring that the impeller converts mechanical energy into electrical energy. Attached Figure Description

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0043] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0044] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a range-extended electric steam generator. Example

[0045] Combination Figures 1 to 11 As shown, the present invention provides a range-extended electric steam generator, comprising an insulated outer tank 100, a steam generating mechanism 200 installed inside the insulated outer tank 100, an exhaust mechanism 300 installed on the steam generating mechanism 200, an electric heating module 400 installed inside the exhaust mechanism 300 and inserted into the steam generating mechanism 200, and a range-extending power supply mechanism 500 installed outside the exhaust mechanism 300. The insulated outer tank 100 is used to provide heat insulation protection for the steam generating mechanism 200. The steam generating mechanism 200 is used to heat the input solution until steam is generated. The exhaust mechanism 300 is used to pressurize and transfer the generated steam. The electric heating module 400 is used to continuously heat the agitated solution inside the steam generating mechanism 200. The range-extending power supply mechanism 500 is used to provide range-extended power to the electric heating module 400.

[0046] The steam generating mechanism 200 includes a heating sleeve 210 and an inner sleeve 230. The liquid storage chambers in the heating sleeve 210 and the inner sleeve 230 are used to store solutions. The bottom of the inner sleeve 230 has multiple evenly distributed slots. A top cover 220 is fixedly installed on the annular port formed at the top of the heating sleeve 210 and the inner sleeve 230. A guide pipe 2201 is installed inside the top cover 220. A bottom pad 240 is fixedly installed at the bottom end of the inner sleeve 230. A column 2401 is fixedly installed at the top of the bottom pad 240. Two symmetrically distributed inner pads 2404 are fixedly installed in each vertical slot 2403. A stabilizing pad 2506 is movably installed in two adjacent inner pads 2404. A pressing head 2507 is fixedly installed at the bottom end of the stabilizing pad 2506, and the outer end of the pressing head 2507 is adapted to be snapped into the slot at the bottom of the inner sleeve 230.

[0047] The back of the stabilizing pad 2506 is fixedly installed with two clamps 2505, two lever arms 2504 and two clamps 2503. The bottom end of the lever arm 2504 is movably installed on the clamp 2505, and the clamp 2503 is movably installed on the top end of the lever arm 2504. There are two clamps 2503. The two clamps 2503 are installed on the outside of the traction rod 250. Two sets of gaskets 2502 for binding the two clamps 2503 are welded to the outside of the traction rod 250.

[0048] The column 2401 has a vertical hole 2405 inside, two clamps 2503 are movably installed inside the vertical hole 2405, and the bottom end of the traction rod 250 is adapted to pass through the middle of the vertical hole 2405. The top plate 2402 is fixedly installed on the top of the column 2401, and the traction rod 250 is adapted to pass through the outside of the top plate 2402.

[0049] The inner wall of the vertical groove 2403 has two holes, and two adjacent lever arms 2504 are adapted to pass through the two holes.

[0050] A pull rod 2501 is fixedly installed at the top of the traction rod 250, and a protective tube 2202 is fixedly installed at the bottom of the top cover 220. Two limiting plates 2203 are welded to the bottom of the inner cavity of the protective tube 2202, and the other end of the pull rod 2501 is adapted to pass through the protective tube 2202, while the pull rod 2501 is located in the gap between the two limiting plates 2203.

[0051] The range extender power supply mechanism 500 includes a housing 510 mounted on four studs 3101 by nuts, a generator 5101 fixedly mounted inside the housing 510, a plug rod 5102 fixedly mounted on the drive shaft of the generator 5101, an energy storage module 520 electrically connected to the generator 5101, a first wire 5201 connected to the energy storage module 520, a control module 530 connected to the energy storage module 520 via the first wire 5201, a second wire 5301 connected to the bottom of the control module 530, a third wire 5302 connected to the top of the control module 530, and an electric heating module 400 connected to the control module 530 via the third wire 5302.

[0052] The outer end of the guide pipe 2201 is connected to the external water pipe in advance, and the water input is controlled by the valve. As the solution enters the liquid storage chamber formed by the heating sleeve 210 and the inner sleeve 230 from the guide pipe 2201, the water pressure will cause the gasket 2103 to drop rapidly. Under the limiting pressure of multiple limiting columns 2102, a sufficiently large gap will be opened between the gasket 2103 and the washer ring 2101, and the solution will flow down along the gap.

[0053] When the solution is squeezed into the inner cavity of the inner sleeve 230 through the groove at the bottom, the control module 530 is energized through the second wire 5301 and then through the third wire 5302 to power the heating module 400. At this time, the heating module 400 will continuously heat the solution in the inner cavity of the inner sleeve 230 until the solution generates high-temperature steam. After the high-temperature steam is pressurized and guided by the exhaust mechanism 300, the exhaust mechanism 300 uses the mechanical energy generated by the steam flow to drive the pull rod 2501 and the traction rod 250 to move up and down repeatedly. The evenly distributed multiple lever arms 2504 will control the evenly distributed multiple stabilizing pads 2506 and multiple extrusion heads 2507 to extend in a regular manner. Finally, the solution in the storage cavity will be sucked into the inner sleeve 230 through the groove at the bottom of the inner sleeve 230 under the action of the extrusion head 2507. The solution entering the inner sleeve 230 can be effectively agitated and the fluidity of the solution is enhanced, thereby accelerating the generation of steam. Example

[0054] Combination Figure 9 As shown, based on Embodiment 1, a gasket 2101 is fixedly installed on the inner wall of the heating sleeve 210, and multiple through holes are evenly distributed inside the gasket 2101. Multiple limiting posts 2102 are movably installed in the through holes. A washer 2103 is fixedly installed at the bottom of the multiple limiting posts 2102, and the washer 2103 is adapted to be inserted into the annular groove between the gasket 2101 and the inner sleeve 230. The top cover 220 has four symmetrically distributed round holes and four fan-shaped holes inside.

[0055] Preferably, the outer wall of the gasket 2101 is welded to the inner wall of the heating sleeve 210, and the limiting column head 2102 is T-shaped. When the gasket 2103 is pressed and the gasket 2101 unfolds, the solution will be rapidly transferred. During the reciprocating extension of the extrusion head 2507 and the pressurization and suction of the solution, the solution rises in the reverse direction in the storage chamber, which will push the gasket 2103 and the gasket 2101 to close quickly, thereby avoiding the reverse pressurization of the solution and causing pressure on the external water pipe or valve. Example

[0056] Combination Figures 3 to 8 As shown, in the above embodiment, the exhaust mechanism 300 includes a sealed end pipe 310 fixedly installed on the top of the top cover 220, four studs 3101 are disposed on the outer wall of the sealed end pipe 310, a load-bearing plate 3102 is fixedly installed on the top of the sealed end pipe 310, a flow guide 330 located inside the sealed end pipe 310 is fixedly installed on the bottom of the load-bearing plate 3102, and four fan-shaped cavities 3301 are opened inside the flow guide 330, and a transverse groove 3302 connecting the four fan-shaped cavities 3301 is opened on the top of the flow guide 330, and four overflow shields 340 are disposed on the inner wall of the four fan-shaped cavities 3301, and the bottom of the overflow shields 340 are installed in the four fan-shaped holes.

[0057] An air pipe 3103 is fixedly installed in the middle of the top surface of the load-bearing plate 3102, and a slot 3104 is provided on the outer wall of the air pipe 3103.

[0058] The interior of the load-bearing plate 3102 is also provided with four circular insertion holes adapted to be symmetrically matched with the four circular holes, and four symmetrically distributed heat dissipation tubes 320 are fixedly installed in the four circular insertion holes, and the heat dissipation tubes 320 are adapted to penetrate into the circular holes.

[0059] The electric heating module 400 is installed on the top of the load-bearing plate 3102, and the four heating sections at the bottom of the electric heating module 400 are respectively inserted into the interior of the four heat dissipation tubes 320.

[0060] Preferably, the load-bearing plate 3102 is fixed to the top of the sealed end pipe 310 by welding, and the bottom of the sealed end pipe 310 is fixed to the top of the top cover 220 by welding. The top of the flow guide shroud 330 is fitted to the bottom of the load-bearing plate 3102. As steam is continuously generated inside the inner sleeve 230 and enters the four overflow shields 340 through the fan-shaped slots in the top cover 220, the airflow is transmitted to the four fan-shaped cavities 3301 through the top holes of the overflow shields 340. Finally, the airflow is discharged upward through the shaft 350. With the continuous pressurization of the solution in the inner sleeve 230, the generated steam will also be further pressurized until the pressurized steam is stably discharged.

[0061] A shaft 350 is movably installed inside the flow guide 330. An impeller 3501 is fixedly installed at the top of the shaft 350. A sliding column 3502 is fixedly installed at the bottom of the shaft 350. A sliding column 3502 is fixedly installed at the bottom of the shaft 350. A slider 3503 is movably installed in the groove on the outer wall of the sliding column 3502. A guide rod 3504 is installed inside the slider 3503. The guide rod 3504 passes through the tube section of the sliding sleeve 3505. A linkage gear is provided at the top of the shaft 350. The linkage gear is located directly below the impeller 3501.

[0062] The outer end of the guide rod 3504 is connected to the top of the pull rod 2501.

[0063] Preferably, the tube section of the sliding sleeve 3505 is movably installed in the gap of the limiting plate 2203. As the impeller 3501 is pressurized by the steam flow and drives the shaft 350 and the sliding column 3502 to rotate, the sliding sleeve 3505, which is limited and constrained by the two limiting plates 2203, will provide effective and stable lifting kinetic energy for the guide rod 3504. The pull rod 2501 and the traction rod 250 can ensure the stability of the evenly distributed multiple stabilizing pads 2506 and multiple extrusion heads 2507.

[0064] The slot 3104 has a housing 540 fixedly installed inside it. The drive rod 5401 is movably installed inside one end of the housing 540, and the shaft 350 is movably installed inside the other end of the housing 540. The drive gear 5402 is fixedly installed outside the drive rod 5401, and both the drive gear 5402 and the linkage gear are located in the inner cavity of the housing 540. The chain 550 is connected to the drive gear 5402 and the linkage gear.

[0065] Preferably, the bottom of the drive rod 5401 is provided with a cross-shaped hole that fits the insertion rod 5102. When the shaft 350 drives the chain 550 to rotate in conjunction with the linkage gear, the other end of the chain 550 will drive the drive gear 5402 and the drive rod 5401 to rotate. The diameter of the linkage gear is twice the diameter of the drive gear 5402. Therefore, the generator 5101 being driven will convert mechanical energy into electrical energy and store it in the energy storage module 520.

[0066] The working principle and usage process of this invention: In use, the solution is transferred to the storage chamber inside the heating sleeve 210 and the inner sleeve 230 by the guide tube 2201. As the solution descends along the storage chamber, the gasket 2103 will descend under the pressure of water and the limiting columns 2102. After the limiting columns 2102 and the gasket 2103 expose the gap, the solution will be guided downward.

[0067] The solution in the storage chamber is transferred inward from the slot at the bottom of the inner sleeve 230, and the solution will immerse the outside of the four heat-releasing tubes 320. The electric heating module 400, which is connected to the external power supply by the second wire 5301 and controlled by the control module 530 and the third wire 5302, will continuously release heat energy into the inner cavity of the four heat-releasing tubes 320. As the four heat-releasing tubes 320 continue to heat up and raise the temperature of the solution immersed in them to the boiling point, the solution will rise in the cavity formed by the inner sleeve 230 and the top cover 220. Finally, the high-temperature steam will be transferred from the slot inside the top cover 220 to the four fan-shaped cavities 3301. As the gas pressure gradually increases, the steam will eventually be guided to the gas pipe 3103 along the horizontal groove 3302. Inside, the continuously increasing air pressure will help the impeller 3501 and shaft 350 rotate, and the linkage gear installed on the shaft 350 will drive the chain 550. The other end of the chain 550 will drive the drive gear 5402 and drive rod 5401 to rotate. Finally, the drive rod 5401 will drive the insertion rod 5102 and the drive shaft inside the generator 5101. Since the diameter of the linkage gear is twice the diameter of the drive gear 5402, after the speed change, the drive rod 5401 will cooperate with the generator 5101 to convert mechanical energy into electrical energy. Finally, the converted electrical energy will be stored in the energy storage module 520. When the external power supply suddenly fails and affects the steam generation of the device, the energy storage module 520 can continue to supply power to the control module 530 through the first wire 5201.

[0068] Meanwhile, the sliding column 3502 installed at the bottom of the shaft 350, together with the sliding sleeve 3505, will assist the slider 3503 and the guide rod 3504 to reciprocate and rise and fall. The pull rod 2501, together with the traction rod 250, will drive the two clamps 2503 to extend in a regular manner. Finally, the two clamps 2503, together with multiple lever arms 2504, will pull the evenly distributed multiple stabilizing pads 2506 and the extrusion head 2507 to extend in a regular manner. The solution in the storage chamber is continuously drawn into the interior of the inner sleeve 230 under the back osmosis protection of the stacked gaskets 2103 and the gasket rings 2101. The drawn-in solution will swirl in the inner cavity of the inner sleeve 230 under high pressure, thereby enhancing the efficiency of steam generation by increasing the fluidity of the solution and the flow rate on the surface of the four inner sleeves 230.

[0069] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
