[0003] Currently, for the existing hot water constant pressure and constant flow supply device, during use, due to the calcium and magnesium ions contained in the water, and the water with calcium and magnesium ions will cause scale on the inner surface of the water tank after heating.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. Through the setting of the magnetization mechanism in the present invention, the magnetization mechanism magnetizes the water inside the water tank, so that the crystal forms of calcium, magnesium and other ions in the water will change, changing from the original chain-like structure to a granular structure, reducing the possibility of minerals forming hard scale on the surface of the pipeline or device, and also promoting the refinement of the formed scale crystal particles, making it easier to be carried away by the water flow, thereby achieving the effects of softening water quality and preventing scale.

[0023] 2. Through the arrangement of multiple magnetization mechanisms in the present invention, when the distance between the magnetic plates installed on adjacent magnetization mechanisms is at its minimum, the magnetic plates will push the sliding plate to slide in the chute and compress the connecting spring under the repulsive force between them. When the minimum distance is exceeded, the sliding plate will slide in the chute under the action of the connecting spring. And since there is no damping structure, the magnetic plates will vibrate, shaking off the magnetic particles and hard scale particles attached to the outer surface of the magnetic plates. At the same time, due to the vibration of the magnetic plates, the magnetic field emitted by the magnetic plates will vibrate, and the vibration of the magnetic field will improve the activity of microorganisms in the water body, promote the reproduction of beneficial bacteria in the water body, inhibit the growth of harmful bacteria, ensure the cleanliness of the water body, and promote the absorption and utilization of water by the human body.

At the same time, due to the arrangement of the magnetic plate, when the magnetic plate rotates away from the state of facing the magnetic block, the arc-shaped rod will knock on the spherical filter screen under the elastic action, causing the spherical filter screen to vibrate and further shaking off the hard scale particles, preventing the blockage of the spherical filter screen and affecting the liquid inflow, ensuring the water extraction volume of the water suction pipe, thereby ensuring the liquid supply pressure and ensuring the state of constant pressure and constant flow liquid supply.

[0037] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non - essential improvements and adjustments to the present application according to the above application content.

[0038] Embodiment: As Figures 1-4 , Figure 6 and Figure 7As shown in the figure, a hot water constant pressure and constant flow liquid supply device includes a water tank 1. A sewage pipe 2 is installed at the bottom of the water tank 1. A water pump two 5 is installed at the top of the water tank 1. The output end of the water pump two 5 is fixedly connected to a water supply pipe 6. A pressure sensor is installed on the water supply pipe 6. The pressure sensor detects the water pressure inside the water supply pipe 6 and sends the detected pressure data to a regulator. The regulator controls a frequency converter to change the output power of the water pump two 5. It should be noted that the pressure sensor, the regulator, and the frequency converter are prior arts and are not shown in the figure and will not be elaborated here in detail, so as to achieve the purpose of constant pressure and constant flow liquid supply. The input end of the water pump two 5 is fixedly connected to a water suction pipe 7. It further includes: a heating mechanism 3. The heating mechanism 3 is installed in the water tank 1 and is located at the lower position inside the water tank 1. The heating mechanism 3 includes an air inlet pipe 301 fixedly connected to the side wall of the water tank 1. The air inlet pipe 301 is connected to an air heat pump. The air heat pump is a prior art and is not shown in the figure and will not be elaborated here in detail. The exhaust end of the air inlet pipe 301 is fixedly connected to an outer heating pipe 302. The outer heating pipe 302 is fixed in the water tank 1 through a fixing rod 303. The end of the outer heating pipe 302 is fixedly connected to a thermoplastic elastomer 304. The end of the thermoplastic elastomer 304 is fixedly connected to an inner heating pipe 305. The outer heating pipe 302, the thermoplastic elastomer 304, and the inner heating pipe 305 form a complete spiral pipeline. The end of the outer heating pipe 302 away from the air inlet pipe 301 is fixedly connected to an exhaust pipe 306. The exhaust pipe 306 is connected to a purification device to reduce environmental pollution. The exhaust pipe 306 is fixedly connected to the side wall of the water tank 1. A knocking rod 307 is fixedly connected to the inner wall of the inner heating pipe 305. The knocking rod 307 is adapted to the outer heating pipe 302. The outer heating pipe 302, the thermoplastic elastomer 304, and the inner heating pipe 305 are all set as spiral shapes. The inner heating pipe 305 has elasticity. A plurality of arc-shaped magnets 308 are fixedly connected to the middle of the outer side of the inner heating pipe 305. There are gaps between the plurality of arc-shaped magnets 308; a water filling component 4. The water filling component 4 is installed in the water tank 1 and is located at the upper position inside the water tank 1. The water filling component 4 includes a water pump one 401 fixedly connected to the top of the water tank 1. The input end of the water pump one 401 is fixedly connected to a water inlet pipe 402. The water inlet pipe 402 is connected to a water source. The output end of the water pump one 401 is fixedly connected to a water filling pipe 403. The end of the water filling pipe 403 is fixedly connected to a water filling ring 404. The water filling ring 404 is sleeved on the water suction pipe 7. The water filling pipe 403 is set as a spiral shape. The water filling pipe 403 is fixedly connected in the water tank 1. A liquid level gauge is installed in the water tank 1 to detect the water volume in the water tank 1. When the water volume is lower than the water filling pipe 403, the water pump one 401 starts. At the same time, when the water tank 1 is full of water, the water pump one 401 shuts down.

[0039] During use, start water pump 1 - 401 so that water pump 1 - 401 draws water through the water inlet pipe 402 into the water filling pipe 403 and injects it into the water tank 1 under the action of the water filling ring 404 until the water tank 1 is full. Then start the air source pump to heat the air. The heated air enters the space composed of the outer heating pipe 302, the thermoplastic elastomer 304, and the inner heating pipe 305 through the air inlet pipe 301 and is discharged through the exhaust pipe 306 to heat the water in the water tank 1 until the user - set temperature is reached. When the user uses it, water pump 2 - 5 will start, draw hot water after filtering the hot water through the ball filter 11 through the water extraction pipe 7, and supply hot water to the user through the water supply pipe 6. During the supply process, the internal water pressure of the water supply pipe 6 is detected by the pressure sensor, and the detected pressure data is sent to the regulator. The regulator controls the frequency converter to change the output power of water pump 2 - 5 so that the hot water supplied by the water supply pipe 6 reaches a constant - pressure and constant - flow state. When the water volume in the water tank 1 is lower than the water filling ring 404, at this time, water pump 1 - 401 starts to fill water into the water tank 1;

[0040] During the water filling process, there is no hot water at the position where the water filling pipe 403 is located. At this time, the internal temperature of the water tank 1 is relatively high. Since the water filling pipe 403 is set in a spiral shape, when there is water flowing through the water filling pipe 403, the temperature inside the water tank 1 will pre - heat the water inside the water filling pipe 403, thus preventing cold water from directly entering the hot water and causing the temperature of the hot water to drop sharply, affecting the comfort of the user's water use.

[0041] As Figures 2-4 、 Figures 7-11 shown, it further includes: a stirring mechanism 8. The stirring mechanism 8 is installed in the middle of the water tank 1 and is wrapped by the heating mechanism 3. The stirring mechanism 8 includes a motor 801 fixedly connected to the bottom of the water tank 1. The output end of the motor 801 is fixedly connected to a rotating shaft 802. A cage 803 is fixedly connected to the rotating shaft 802. A rotating rod 804 is rotatably connected to the cage 803. A plurality of rotating rods 804 are provided. The top of the rotating rod 804 is rotatably connected to a rotating ring 805. A plurality of water filling holes 806 are opened in the rotating ring 805. A gear 808 is fixedly connected to the bottom of the rotating rod 804. A groove is opened in the inner bottom of the water tank 1. A sealing ring 807 is rotatably connected in the groove. The rotating rod 804 passes through the sealing ring 807 and is rotatably connected to the sealing ring 807. A toothed ring 809 is fixedly connected in the groove. The gear 808 meshes with the toothed ring 809. A conveying blade 810 is fixedly connected to the rotating rod 804. The rotating shaft 802 passes through the bottom of the water tank 1 and is rotatably connected to the water tank 1. The rotating ring 805 is rotatably connected to the bottom of the water filling ring 404, and the inside of the rotating ring 805 and the water filling ring 404 is in communication.

[0042] During use, the motor 801 is started, causing the motor 801 to drive the cage 803 to rotate through the rotating shaft 802, thereby driving the rotating rod 804 to revolve. When the rotating rod 804 revolves, the rotating ring 805 rotates, enabling the water filling hole 806 to add water at a lower temperature to the hot water more evenly, so that the water at a lower temperature can be heated faster. At the same time, the rotating rod 804 will rotate under the action of the gear 808 and the toothed ring 809, thereby driving the conveying blade 810 to rotate while revolving, mixing the water at a lower temperature and the hot water, and conveying the hot water at the bottom upward, further shortening the heating time of the water at a lower temperature and preventing the water supplied to the user from being alternately hot and cold.

[0043] As Figure 2 , Figure 4 , Figures 7-11 shown, it further includes: a magnetization mechanism 9. The magnetization mechanism 9 is provided in multiple groups and is installed on the agitation mechanism 8 for magnetizing water and changing the inner diameter of the heating mechanism 3. The magnetization mechanism 9 includes fixing plates 901 fixedly connected to the rotating rod 804. There are two fixing plates 901, located at the upper and lower ends of the conveying blade 810. The number of the magnetization mechanisms 9 is the same as the number of the rotating rods 804. A sliding groove 902 is formed in the fixing plate 901, and a sliding plate 903 is slidably connected in the sliding groove 902. One side of the sliding plate 903 is fixedly connected with a connecting spring 904. The connecting spring 904 is arranged in the sliding groove 902, and the end of the connecting spring 904 away from the sliding plate 903 is fixedly connected to the fixing plate 901. The end of the sliding plate 903 is fixedly connected with a magnetic plate 905. The magnetic plate 905 is slidably connected in the fixing plate 901. The rotating rod 804 passes through the fixing plate 901 and is fixedly connected to the fixing plate 901. The conveying blade 810 is located between the fixing plate 901 and the magnetic plate 905. A plurality of arc-shaped magnets 308 fixedly connected to the middle part of the outer side of the inner heating tube 305 are adapted to the magnetic plate 905. When the distance between the magnetic plate 905 and the inner heating tube 305 reaches the minimum, the magnetic plate 905 will attract the inner heating tube 305 to move inward, increasing the distance between the inner heating tube 305 and the outer heating tube 302. When the distance between the magnetic plate 905 and the inner heating tube 305 deviates from the minimum distance, the thermoplastic elastomer 304 will drive the inner heating tube 305 to rebound outward.

[0044] During use, when the rotating rod 804 rotates and revolves, it will drive the magnetic plate 905 to rotate and revolve. During this process, when the distance between the magnetic plates 905 on two adjacent magnetization mechanisms 9 is the smallest, the magnetic plates 905 will slide in opposite directions under the action of repulsive force, thereby causing the sliding plate 903 to slide in the sliding groove 902 and squeezing the connecting spring 904. When the distance between the magnetic plates 905 on two adjacent magnetization mechanisms 9 deviates from the minimum distance, the sliding plate 903 will slide in the sliding groove 902 under the action of the connecting spring 904, thereby causing the magnetic plate 905 to slide outwards. At this time, since there is no damping structure in the magnetization mechanism 9, the magnetic plate 905 will vibrate under the action of the connecting spring 904;

[0045] This realizes shaking off the magnetic particles and hard scale particles attached to the outer surface of the magnetic plate 905. At the same time, due to the vibration of the magnetic plate 905, the magnetic field emitted by the magnetic plate 905 will vibrate. The vibration of the magnetic field will improve the activity of microorganisms in the water, promote the reproduction of beneficial bacteria in the water, inhibit the growth of harmful bacteria, ensure the cleanliness of the water, promote the absorption and utilization of water by the human body, and during the rotation and revolution of the magnetic plate 905, the water passing through the magnetic field emitted by the magnetic plate 905 can be magnetized, causing the crystal forms of calcium, magnesium and other ions in the water to change, from the original chain structure to a granular structure, reducing the possibility of minerals forming hard scale on the surface of pipelines or devices, and also promoting the refinement of the formed scale crystal particles, making them easier to be carried away by the water flow, thus achieving the effects of softening water quality and preventing scale;

[0046] During this process, when the distance between the magnetic plate 905 and the inner heating pipe 305 reaches the minimum, the magnetic plate 905 will attract the inner heating pipe 305 to move inwards, and at the same time stretch the thermoplastic elastomer 304, increasing the distance between the inner heating pipe 305 and the outer heating pipe 302, slowing down the flow rate of the hot gas in the inner heating pipe 305, the thermoplastic elastomer 304 and the outer heating pipe 302, thereby increasing the residence time of the hot gas between the inner heating pipe 305, the thermoplastic elastomer 304 and the outer heating pipe 302, enabling the heat emitted by the hot gas to be utilized more fully, improving the heating efficiency of the hot gas for water, and reducing energy consumption;

[0047] When the magnetic plate 905 disengages from the minimum distance from the inner heating pipe 305, the inner heating pipe 305 will move outward and reset under the action of the stretched thermoplastic elastomer 304, causing the knocking rod 307 to strike the outer heating pipe 302; the outer heating pipe 302 drives the inner heating pipe 305 and the thermoplastic elastomer 304 to vibrate, so that the hard scale attached to its outer surface detaches from the outer heating pipe 302, the inner heating pipe 305 and the thermoplastic elastomer 304 under the action of vibration, reducing the corrosion caused by the hard scale to the outer heating pipe 302, the inner heating pipe 305 and the thermoplastic elastomer 304, preventing the slow heat conduction efficiency caused by the accumulation of hard scale, ensuring the heat conduction efficiency, and reducing the energy loss.

[0048] As Figure 5 and Figure 11 shown, it further includes: an inner cleaning mechanism 10. A spherical filter screen 11 is fixedly connected to the bottom of the water extraction pipe 7. The inner cleaning mechanism 10 is installed in the water extraction pipe 7 and the spherical filter screen 11 for cleaning the spherical filter screen 11. The inner cleaning mechanism 10 includes a fixed column 1001 fixedly connected in the water extraction pipe 7. A plugging rod 1002 is fixedly connected to the bottom of the fixed column 1001. A rotating pipe 1003 is rotatably connected to the bottom of the plugging rod 1002. An arc-shaped rod 1004 is fixedly connected to the side wall of the rotating pipe 1003. The arc-shaped rod 1004 is elastic. A magnetic block 1006 is fixedly connected to the free end of the arc-shaped rod 1004. A cleaning ball 1005 is fixedly connected to the side wall of the arc-shaped rod 1004. The arc-shaped rod 1004 fits against the inner wall of the spherical filter screen 11. The cleaning ball 1005 is arranged on the side where the arc-shaped rod 1004 fits against the spherical filter screen 11. The cleaning ball 1005 can be compressed, and the diameter of the cleaning ball 1005 is 1.5 times the diameter of the holes of the spherical filter screen 11. The rotating pipe 1003 is fixedly connected to the top of the rotating shaft 802. The rotating pipe 1003 penetrates through the spherical filter screen 11 and is rotatably connected to the spherical filter screen 11. The magnetic block 1006 is adapted to the magnetic plate 905.

[0049] During use, during the process of the water extraction pipe 7 pumping water, the rotation of the rotating shaft 802 will drive the rotating pipe 1003 to rotate, and then drive the arc-shaped rod 1004 to rotate, causing the cleaning ball 1005 to move along the inner wall of the spherical filter screen 11. When the cleaning ball 1005 reaches the position of the holes of the spherical filter screen 11, the cleaning ball 1005 enters the holes of the spherical filter screen 11 under the extrusion of the holes of the spherical filter screen 11, dredging the holes of the spherical filter screen 11. And because the rotating shaft 802 is in a continuous rotation state, all the holes of the spherical filter screen 11 can be dredged, realizing the effective cleaning of the spherical filter screen 11;

[0050] Meanwhile, during this process, when the magnetic plate 905 rotates to face the position where the magnetic block 1006 is located, the magnetic block 1006 will move inward under the repulsive force of the magnetic plate 905, driving the curved rod 1004 to bend. When the magnetic plate 905 rotates away from the position facing the magnetic block 1006, the magnetic block 1006 loses the repulsive force of the magnetic plate 905, causing the elastic curved rod 1004 to impact the spherical filter screen 11 under the action of elasticity, making the spherical filter screen 11 vibrate and shake off the hard scale attached to its outer surface;

[0051] Prevent the blockage of the spherical filter screen 11, which affects the liquid inflow, ensure the water extraction volume of the water suction pipe 7, thus ensuring the supply pressure of the liquid, and ensuring the state of constant pressure and constant flow liquid supply.

[0052] It should be noted that the specific working principle of this hot water constant pressure and constant flow liquid supply device is as follows:

[0053] During use, start the first water pump 401 so that the first water pump 401 extracts water through the water inlet pipe 402 and injects it into the water tank 1 under the action of the water adding ring 404 until the water tank 1 is full. Then start the air source pump to heat the air. The heated air enters the space composed of the outer heating pipe 302, the thermoplastic elastomer 304 and the inner heating pipe 305 through the air inlet pipe 301 and is discharged through the exhaust pipe 306 to heat the water in the water tank 1 until the heating temperature is reached. When the user uses it, the second water pump 5 will start, extract hot water after filtering through the spherical filter screen 11 through the water suction pipe 7, and supply hot water to the user through the water supply pipe 6. During the supply process, the water pressure inside the water supply pipe 6 is detected by the pressure sensor, and the detected pressure data is sent to the regulator. The regulator controls the frequency converter to change the output power of the second water pump 5, so that the hot water supplied by the water supply pipe 6 reaches the state of constant pressure and constant flow. When the water volume in the water tank 1 is lower than the water adding ring 404, the first water pump 401 starts to add water to the water tank 1;

[0054] During the water adding process, there is no hot water at the position where the water adding pipe 403 is located. At this time, the temperature inside the water tank 1 is relatively high. Since the water adding pipe 403 is set in a spiral shape, when there is water flowing through the water adding pipe 403, the temperature inside the water tank 1 will preheat the water inside the water adding pipe 403, thus preventing cold water from directly entering the hot water, resulting in a sharp drop in the temperature of the hot water and affecting the comfort of the user's water use;

[0055] During the water filling process, the motor 801 is started, and the motor 801 drives the cage 803 to rotate through the rotating shaft 802, thereby driving the rotating rod 804 to revolve. When the rotating rod 804 revolves, the rotating ring 805 rotates, so that the water filling hole 806 can add the relatively cold water into the hot water more evenly, enabling the relatively cold water to be heated faster. At the same time, the rotating rod 804 will rotate on its own under the action of the gear 808 and the toothed ring 809, thereby driving the conveying blade 810 to rotate on its own while revolving, mixing the relatively cold water and the hot water, and conveying the hot water at the bottom upward, further shortening the heating time of the relatively cold water and preventing the water supplied to the user from being alternately hot and cold;

[0056] At the same time, during the rotation and revolution of the rotating rod 804, the magnetic plate 905 will be driven to rotate and revolve. During this process, when the distance between the magnetic plates 905 on two adjacent magnetization mechanisms 9 is the smallest, the magnetic plates 905 will slide in opposite directions under the action of the repulsive force, thereby causing the sliding plate 903 to slide in the sliding groove 902 and squeezing the connecting spring 904. When the distance between the magnetic plates 905 on two adjacent magnetization mechanisms 9 deviates from the minimum distance, the sliding plate 903 will slide in the sliding groove 902 under the action of the connecting spring 904, causing the magnetic plate 905 to slide outward. At this time, since there is no damping structure in the magnetization mechanism 9, the magnetic plate 905 will vibrate under the action of the connecting spring 904, realizing the shaking off of the magnetic particles and hard scale particles attached to the outer surface of the magnetic plate 905;

[0057] During this process, when the distance between the magnetic plate 905 and the inner heating tube 305 reaches the minimum, the magnetic plate 905 will attract the inner heating tube 305 to move inward and contract, and at the same time, the thermoplastic elastomer 304 will be stretched, increasing the distance between the inner heating tube 305 and the outer heating tube 302, slowing down the flow rate of the hot gas in the inner heating tube 305, the thermoplastic elastomer 304 and the outer heating tube 302, thereby increasing the residence time of the hot gas between the inner heating tube 305, the thermoplastic elastomer 304 and the outer heating tube 302, enabling the heat dissipated by the hot gas to be utilized more fully, improving the heating efficiency of the hot gas for water, and reducing energy consumption;

[0058] When the magnetic plate 905 disengages from the minimum distance from the inner heating pipe 305, the inner heating pipe 305 will move outward and reset under the action of the stretched thermoplastic elastomer 304, causing the knocking rod 307 to strike the outer heating pipe 302; the outer heating pipe 302 drives the inner heating pipe 305 and the thermoplastic elastomer 304 to vibrate, so that the hard scale attached to its outer surface detaches from the outer heating pipe 302, the inner heating pipe 305 and the thermoplastic elastomer 304, reducing the corrosion of the hard scale on the outer heating pipe 302, the inner heating pipe 305 and the thermoplastic elastomer 304, preventing the heat conduction efficiency from slowing down due to the accumulation of hard scale, ensuring the heat conduction efficiency, and reducing the energy loss;

[0059] During the process of the water suction pipe 7 sucking water, the rotation of the rotating shaft 802 will drive the rotating pipe 1003 to rotate, and then drive the arc-shaped rod 1004 to rotate, so that the cleaning ball 1005 moves along the inner wall of the spherical filter screen 11. When the cleaning ball 1005 reaches the position of the hole of the spherical filter screen 11, the cleaning ball 1005 enters the hole of the spherical filter screen 11 under the extrusion of the hole of the spherical filter screen 11, dredging the hole of the spherical filter screen 11. And because the rotating shaft 802 is in a continuous rotating state, all the holes of the spherical filter screen 11 can be dredged, realizing the effective cleaning of the spherical filter screen 11;

[0060] At the same time, during this process, when the magnetic plate 905 rotates to the position directly opposite the magnetic block 1006, the magnetic block 1006 will move inward under the repulsive force of the magnetic plate 905, driving the arc-shaped rod 1004 to bend. When the magnetic plate 905 rotates away from the position directly opposite the magnetic block 1006, the magnetic block 1006 loses the repulsive force of the magnetic plate 905, and the elastic arc-shaped rod 1004 impacts the spherical filter screen 11 under the action of elasticity, causing the spherical filter screen 11 to vibrate and shake off the hard scale attached to its outer surface;

[0061] Prevent the blockage of the spherical filter screen 11, which affects the liquid inflow, ensure the water extraction volume of the water suction pipe 7, thereby ensuring the liquid supply pressure and ensuring the state of constant pressure and constant flow liquid supply.

[0062] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
