After the motor 201 on the top side of the water tank 1 is electrically connected to the external power supply, the piston plate 207 can be driven to move up and down in the water tank 1 by the driving action of the motor 201. After the two connecting holes 8 on the bottom side of the water tank 1 are respectively connected to the water inlet pipe and the water outlet pipe, the water in the water tank 1 can be extracted and released by the lifting and lowering of the piston plate 207 combined with the opening and closing of the water inlet pipe and the water outlet pipe. At the same time, since the water in the water tank 1 enters or is discharged by the squeezing of the piston plate 207, it can be ensured that the water surface can always be in contact with the insulation plate 205 on the bottom side of the piston plate 207, so that the insulation material can give full play to the insulation effect.

[0025] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Fig.10 As shown, the heat storage structure 3 includes a first connecting pipe 301, the bottom end of the water storage tank 1 is fixedly connected with the first connecting pipe 301, the conversion pipe 206 is rotatably connected to the water storage tank 1, the bottom end of the conversion pipe 206 is communicated with the end of the first connecting pipe 301, the other end of the first connecting pipe 301 is connected to a heat collector 302, the bottom side of the heat collector 302 is connected with a second connecting pipe 303, the other end of the second connecting pipe 303 is communicated with the bottom of the water storage tank 1, a valve 304 is installed on one side of the second connecting pipe 303, the heat collector 302 is arranged on the bottom side of the water storage tank 1, a conversion hole 305 is opened at both ends of the conversion pipe 206, and the two conversion holes 305 are respectively arranged on both sides of the conversion pipe 206, and the two ends of the conversion pipe 206 are rotatably connected with sealing pads 306, the sealing pads 306 are "C"-shaped structure, and the sealing pads 306 are fixedly connected to the water storage tank 1; When the weather is cold, the conversion tube 206 in the water storage tank 1 can be rotated so that the conversion hole 305 on the bottom side of the conversion tube 206 turns to the other side and is sealed by the corresponding sealing gasket 306. At the same time, the conversion hole 305 on the top of the conversion tube 206 changes direction at the same time, breaking away from the sealing state of the corresponding sealing gasket 306. Since the two sides of the collector 302 are connected to the inner side of the water storage tank 1 through the first connecting pipe 301 and the second connecting pipe 303 respectively, the two connecting holes 8 connected to the bottom side of the water storage tank 1 are closed. After the conversion tube 206 rotates, the first connecting tube 301 will be connected to the cavity on the top side of the piston plate 207. At this time, if the piston plate 207 is driven to rise by the motor 201, the air on the top side of the piston plate 207 will be pressed into the collector 302 through the conversion tube 206 and the first connecting tube 301, thereby discharging the water in the collector 302. When the collector 302 is emptied, the user needs to close the valve 304 on the second connecting tube 303 to prevent the collector 302 from being damaged due to ice.

[0026] Specifically, Figure 1 , Figure 6 As shown, the conversion structure 4 includes a control rod 401, the top of the water tank 1 is rotatably connected with the control rod 401, the control rod 401 is fixedly connected to the top of the conversion tube 206, the top side of the water tank 1 is fixedly connected with a limit block 402, the limit block 402 is a semicircular structure, the control rod 401 conflicts with the side of the limit block 402, the inner side of the control rod 401 is slidably connected with a driving slide rod 403, a first spring 404 is fixedly connected between the driving slide rod 403 and the control rod 401, the end of the driving slide rod 403 is vertically fixedly connected with a plug rod 405, two first slots 406 are provided on the water tank 1, and the plug rod 405 is engaged with the water tank 1 through the first slots 406; In order to facilitate the user to control the rotation of the conversion tube 206, a control rod 401 is provided at the top of the conversion tube 206, and the rotation range of the control rod 401 is limited by the limit block 402. When the control rod 401 is rotated from one side to the other side, a rotation adjustment of the conversion tube 206 is completed. At the same time, in order to fix the rotation position of the conversion tube 206, a driving slide bar 403 is provided on the inner side of the control rod 401. The insertion rod 405 at the end of the driving slide bar 403 will engage with the first slot 406 on the water tank 1 to fix the current position of the control rod 401. When the control rod 401 needs to be rotated, the user needs to press the driving slide bar 403 at the end at the same time to release the engagement state of the insertion rod 405 and the first slot 406. When the control rod 401 turns to the other side, the driving slide bar 403 can be released for repositioning.

[0027] Specifically, Figure 1 , Figure 3 , Figure 5 As shown, the positioning structure 5 includes a positioning through hole 501, a positioning through hole 501 is provided on the side of the water storage tank 1, a guide groove 506 is provided on the top side of the piston plate 207, and the piston plate 207 is slidably connected with a snap-fit ​​frame 502 through the guide groove 506, and the end of the snap-fit ​​frame 502 is fixedly connected with a ramp block 504, and the ramp block 504 is snap-fitted with the side wall of the water storage tank 1 through the positioning through hole 501, and a second spring 505 is fixedly connected between the end of the snap-fit ​​frame 502 away from the ramp block 504 and the piston plate 207, and the conversion tube 206 passes through the snap-fit ​​frame 502, and a second snap-fitting groove 503 is provided on the side of the conversion tube 206, and the inner side of the snap-fit ​​frame 502 is a ramp structure, and the snap-fit ​​frame 502 is snap-fitted with the conversion tube 206 through the second snap-fitting groove 503; When the conversion tube 206 is in different positions, in order to ensure the normal lifting of the piston plate 207, a one-way air inlet valve 202 is provided on the top side of the water tank 1, and a positioning through hole 501 is provided on the side of the water tank 1. When the bottom end of the conversion tube 206 is connected to the water tank 1, that is, at this time, the first connecting pipe 301 and the second connecting pipe 303 are both connected to the bottom side of the water tank 1, the water in the water tank 1 will fill the heat collector 302, which is used to exchange heat with the water in the water tank 1. At the same time, the positioning through hole 501 can balance the cavity on the top side of the piston plate 207 with the external air pressure, thereby ensuring that the piston plate 20 7 is raised and lowered normally to ensure the normal entry or discharge of hot water, and when the top conversion hole 305 of the conversion tube 206 is connected to the inner side of the water storage tank 1, the user can empty the collector 302 by lifting the piston plate 207. When the emptying step is completed, the piston plate 207 can be normally lowered and reset through the balancing effect of the one-way air inlet valve 202. When the piston plate 207 moves below the positioning through hole 501, the first connecting pipe 301 and the second connecting pipe 303 are both in a closed state, which is equivalent to completing the emptying of the collector 302 and removing the collector 303. 02, open the inlet and outlet water pipes connected by the two connecting holes 8 for normal use, providing protection for the collector 302 under cold conditions while preventing heat from being lost through the collector 302; on the other hand, due to the presence of the positioning through hole 501, the air in the water storage tank 1 above the positioning through hole 501 is used to empty the collector 302. In normal use, the piston plate 207 should remain below the positioning through hole 501 for movement to avoid leakage of hot water. In order to position the movement of the piston plate 207, a snap-fit ​​frame 502 is provided on the top side of the piston plate 207. When 302 is in normal use, the piston plate 207 moves frequently. At this time, the second slot 503 on the side of the conversion tube 206 will face the first screw 204. When the piston plate 207 moves to the position of the positioning hole 501, the locking frame 502 will be locked with the second slot 503 under the push of the second spring 505, and the inclined block 504 at the end of the locking frame 502 will also be locked with the positioning hole 501 at the same time, preventing the piston plate 207 from continuing to rise. Due to the inclined surface of the locking frame 502 and the inclined block 504, the piston plate 207 can descend normally, making it convenient to take hot water.

[0028] Specifically, Figure 1 , Figure 2 , Figure 4 , Fig. 9 , Fig.10 , Fig.11 , Fig.12As shown, the support structure 6 includes a support column 601, and a plurality of support columns 601 are slidably connected to the side of the water tank 1, and a threaded toothed ring 604 is threadedly connected to the support column 601, and the threaded toothed ring 604 is rotatably connected to the water tank 1, and a synchronous toothed ring 603 is rotatably connected to the bottom side of the water tank 1, and the synchronous toothed ring 603 and the threaded toothed ring 604 are meshed with each other, and a transmission gear 605 is rotatably connected to the side of the water tank 1, and the transmission gear 605 is meshed with the synchronous toothed ring 603, and a first bevel gear 606 is fixedly connected to the transmission gear 605, and a second bevel gear 607 is meshed on the side of the first bevel gear 606, and an adjusting rod 602 is fixedly connected to the middle of the second bevel gear 607, and the adjusting rod 602 is rotatably connected to the water tank 1; In order to facilitate the installation of the water tank 1 and the normal operation of the collector 302, the user can adjust the height of the water tank 1 by rotating the adjusting rod 602 located on the side of the water tank 1. The rotation of the adjusting rod 602 drives the transmission gear 605 to rotate through the transmission effect of the first bevel gear 606 and the second bevel gear 607. The rotation of the transmission gear 605 can further drive the synchronous gear ring 603 to rotate. The threaded gear ring 604 threadedly connected to the support column 601 is respectively engaged with the side of the synchronous gear ring 603. As the threaded gear ring 604 rotates, the supporting position of the support column 601 for the water tank 1 can be adjusted, thereby adjusting the installation height of the water tank 1.

[0029] Specifically, Figure 7 , Fig.10 , Fig.12 As shown, the observation structure 7 includes an indicator groove 703, the side of the water storage tank 1 is provided with an indicator groove 703, the indicator groove 703 is provided with a second screw 702, the bottom end of the second screw 702 is rotatably connected to the water storage tank 1, the top of the second screw 702 is threadedly connected with a sealing block 701, the bottom end of the sealing block 701 is a square structure, the top of the sealing block 701 is in conflict with the water storage tank 1, and the side of the water storage tank 1 is fixedly connected with a transparent plate 70 4. A threaded block 705 is slidably connected in the water storage tank 1. The threaded block 705 is threadedly connected to the second screw rod 702. A sealing head 706 is slidably connected to the end of the threaded block 705. A third spring 707 is fixedly connected between the sealing head 706 and the threaded block 705. A connecting pipe 708 is fixedly connected to the side wall of the water storage tank 1. The end of the sealing head 706 is an arc surface structure, and the end of the sealing head 706 conflicts with the end of the connecting pipe 708. Since an inner insulation layer 203 is added in the water tank 1, it is not convenient to directly check the liquid level position in the water tank 1. When the user wants to know the water level position in the water tank 1, the user can rotate the second screw 702 located on the bottom side of the water tank 1. At this time, the sealing blocks 701 and threaded blocks 705 at both ends of the second screw 702 will move toward the top side at the same time. After the threaded block 705 is moved, the sealing head 706 on the inside thereof will release the sealing effect on the connecting pipe 708. At the same time, the sealing block 701 on the top side of the second screw 702 will also release the sealing effect on the top side of the indicator groove 703. At this time, the water inside the water tank 1 will flow into the indicator groove 703 and be flush with the liquid level in the water tank 1. At this time, the user can directly check through the transparent plate 704 on the side, and then turn the second screw 702 back to make the connecting pipe 708 re-seal to ensure the overall insulation effect of the water tank 1.

[0030] When the present invention is in use, first, an inner layer of the water tank 1 for storing hot water is provided with an inner insulation layer 203, and at the same time, a piston plate 207 that can be raised and lowered is provided on the inner side of the water tank 1. After the motor 201 on the top side of the water tank 1 is electrically connected to an external power supply, the piston plate 207 can be driven to move up and down in the water tank 1 by the driving action of the motor 201. After the two connecting holes 8 on the bottom side of the water tank 1 are respectively connected to the water inlet pipe and the water outlet pipe, the water in the water tank 1 can be extracted and released by the lifting and lowering of the piston plate 207 combined with the opening and closing of the water inlet pipe and the water outlet pipe. At the same time, since the water in the water tank 1 enters or is discharged by the squeezing of the piston plate 207, it can be ensured that the water surface can always be in contact with the bottom side of the piston plate 207. The heat preservation plate 205 is in contact with each other, so that the heat preservation material can fully exert its heat preservation effect. When the weather is cold, the conversion tube 206 in the water storage tank 1 can be rotated, so that the bottom conversion hole 305 of the conversion tube 206 turns to the other side and is sealed by the corresponding sealing gasket 306. At the same time, the conversion hole 305 at the top of the conversion tube 206 changes direction at the same time, and is separated from the sealing state of the corresponding sealing gasket 306. Since the two sides of the collector 302 are connected to the inner side of the water storage tank 1 through the first connecting tube 301 and the second connecting tube 303 respectively, after closing the pipeline connected to the two connecting holes 8 on the bottom side of the water storage tank 1, as the conversion tube 206 rotates, the first connecting tube 301 will be connected to the cavity on the top side of the piston plate 207. At this time, if the motor 2 01 drives the piston plate 207 to rise, then the air on the top side of the piston plate 207 will be pressed into the collector 302 through the conversion tube 206 and the first connecting tube 301, so as to discharge the water in the collector 302. When the collector 302 is emptied, the user needs to close the valve 304 on the second connecting tube 303 to prevent the collector 302 from being damaged due to ice. In order to facilitate the user to control the rotation of the conversion tube 206, a control rod 401 is provided at the top of the conversion tube 206. The rotation range of the control rod 401 is limited by the limit block 402. When the control rod 401 is rotated from one side to the other side, the conversion tube 206 is adjusted once. At the same time, in order to fix the rotation position of the conversion tube 206, the position A driving slide bar 403 is provided on the inner side of the control rod 401, and the plug rod 405 at the end of the driving slide bar 403 will engage with the first slot 406 on the water tank 1 to fix the current position of the control rod 401. When the control rod 401 needs to be rotated, the user needs to press the driving slide bar 403 at the end at the same time to release the engagement state of the plug rod 405 and the first slot 406. When the control rod 401 turns to the other side, the driving slide bar 403 can be released to reposition. When the conversion tube 206 is in different positions, in order to ensure the normal lifting of the piston plate 207, a one-way air intake valve 202 is provided on the top side of the water tank 1, and a positioning through hole 501 is opened on the side of the water tank 1. When the bottom end of the conversion tube 206 is connected to the water tank 1,That is, at this time, the first connecting pipe 301 and the second connecting pipe 303 are both connected to the bottom side of the water tank 1. At this time, the water in the water tank 1 will fill the heat collector 302, which is used to exchange heat with the water in the water tank 1. At the same time, the positioning through hole 501 can make the cavity on the top side of the piston plate 207 balanced with the external air pressure, thereby ensuring the normal lifting and lowering of the piston plate 207 and thus ensuring the normal entry or discharge of hot water. When the top conversion hole 305 of the conversion tube 206 is connected to the inner side of the water tank 1, the user can empty the heat collector 302 by lifting the piston plate 207. When the emptying step is completed, the piston plate 207 can be normally lowered and reset through the balancing effect of the one-way air inlet valve 202. When the piston plate 207 moves to the positioning through hole 501, the piston plate 207 can be lowered and reset. After that, the first connecting pipe 301 and the second connecting pipe 303 are both in a closed state, which is equivalent to completing the emptying of the heat collector 302 and removing the heat collector 302. The water inlet and outlet pipes connected by the two connecting holes 8 can be opened for normal use, providing protection for the heat collector 302 under cold conditions while preventing heat from being lost through the heat collector 302; on the other hand, due to the presence of the positioning through hole 501, the air in the water storage tank 1 above the positioning through hole 501 is used to empty the heat collector 302. In normal use, the piston plate 207 should remain below the positioning through hole 501 for movement to avoid leakage of hot water. In order to position the movement of the piston plate 207, a snap-fit ​​frame 5 is provided on the top side of the piston plate 207. 02, when the collector 302 is in normal use, the movement of the piston plate 207 is relatively frequent. At this time, the second slot 503 on the side of the conversion tube 206 will face the first screw 204. When the piston plate 207 moves to the position of the positioning through hole 501, the engaging frame 502 will be engaged with the second slot 503 under the push of the second spring 505, and the inclined block 504 at the end of the engaging frame 502 will also be engaged with the positioning through hole 501 at the same time, preventing the piston plate 207 from continuing to rise. Due to the inclined surface of the engaging frame 502 and the inclined surface block 504, the piston plate 207 can be normally lowered, which is convenient for taking hot water. In order to facilitate the installation of the water storage tank 1 and the normal operation of the collector 302, the user can turn the adjustment knob on the side of the water storage tank 1 to adjust the position of the water storage tank 1. The section rod 602 is used to adjust the height of the water tank 1. The rotation of the adjustment rod 602 drives the transmission gear 605 to rotate through the transmission effect of the first bevel gear 606 and the second bevel gear 607. The rotation of the transmission gear 605 can further drive the synchronous gear ring 603 to rotate. The threaded gear ring 604 threadedly connected to the support column 601 is respectively engaged with the side of the synchronous gear ring 603. With the rotation of the threaded gear ring 604, the supporting position of the support column 601 for the water tank 1 can be adjusted, thereby adjusting the installation height of the water tank 1. Since the inner insulation layer 203 is added to the water tank 1, it is not convenient to directly check the liquid level position in the water tank 1. When the user wants to know the water level position in the water tank 1, the user can rotate the second screw 702 located on the bottom side of the water tank 1.At this time, the sealing blocks 701 and the threaded blocks 705 at both ends of the second screw 702 will move toward the top side at the same time. After the threaded block 705 moves, the sealing head 706 inside it will release the sealing effect on the connecting pipe 708. At the same time, the sealing block 701 on the top side of the second screw 702 will also release the sealing effect on the top side of the indicator groove 703. At this time, the water inside the water storage tank 1 will flow into the indicator groove 703 and be flush with the liquid level in the water storage tank 1. At this time, the user can directly check through the transparent plate 704 on the side, and then turn the second screw 702 back to make the connecting pipe 708 re-seal to ensure the overall thermal insulation effect of the water storage tank 1.
