Description

Technical Field

[0001] This application relates to the technical field of air - energy heating equipment, and particularly to a new type of water tank structure. Background Art

[0002] An air - energy water heater is an energy - saving heating equipment that utilizes air heat sources. It absorbs low - temperature heat in the air, vaporizes through a fluorine medium, then compresses and boosts the temperature through a compressor, and then converts the heat to heat water through a heat exchanger. The compressed high - temperature heat energy is used to heat the water temperature, and a heat - preservation water tank is used to keep the heated water warm. With the development of air - energy water heaters, in order to reduce the heat loss of hot water during transportation in pipelines, the existing air - energy water heater systems often place the heat exchanger inside the heat - preservation water tank.

[0003] Most of the existing automatic water - replenishing solutions for heat - preservation water tanks adopt the method of float valves. That is, when the water level in the heat - preservation water tank drops to a certain level, the float ball opens the valve to automatically replenish water as the water level drops. In this way, cold water will be automatically replenished synchronously during the continuous use of hot water, resulting in a continuous drop in water temperature and affecting subsequent use. In addition, scale will form on the inner wall of the heat - preservation water tank after long - term use, which not only affects water quality but also reduces the water storage capacity and heat - preservation efficiency of the water tank. Summary of the Invention

[0004] In order to improve the water temperature constancy and heat - preservation efficiency of the water tank during continuous water use and reduce the scale in the water tank, this application provides a new type of water tank structure.

[0005] A new type of water tank structure provided by this application adopts the following technical solutions:

[0006] A new type of water tank structure, comprising:

[0007] A heating cylinder, which is used for heating and storing water sources, and an inlet is opened on the heating cylinder to connect the inner cavity of the heating cylinder and an external water supply pipe.

[0008] A heat - preservation cylinder, which is arranged inside the heating cylinder and used for storing heated water sources; a communication hole connecting the inner cavity of the heating cylinder and the inner cavity of the heat - preservation cylinder and an outlet connecting the inner cavity of the heat - preservation cylinder are opened on the heat - preservation cylinder.

[0009] Interception and descaling component, the interception and descaling component includes a scraping ring, a switch plate, a first magnetic member and a second magnetic member; the scraping ring is arranged inside the heat preservation cylinder, and the outer wall of the scraping ring is in sliding contact with the inner wall of the heat preservation cylinder, and the scraping ring can slide up and down along the inner wall of the heat preservation cylinder; the switch plate is rotatably arranged on the heat preservation cylinder, and the switch plate can cover the communication hole in the free state; the first magnetic member is arranged on the switch plate, and the second magnetic member is arranged on the scraping ring; when the scraping ring is at the lowest position inside the heat preservation cylinder, the second magnetic member generates a repulsive force with the first magnetic member to push the switch plate to flip and open the communication hole; when the scraping ring rises, the second magnetic member and the first magnetic member do not interfere with each other;

[0010] Power component, the power component can drive the scraping ring to rise by using the water flow impact force when the water outlet discharges water, and the scraping ring can freely fall to the lowest position inside the heat preservation cylinder when the water outlet stops discharging water.

[0011] By adopting the above technical solution, the water temperature constancy and heat preservation efficiency of the water tank during continuous water use can be improved, and the scale in the water tank can be reduced; specifically, the external water source enters the inner cavity of the heating cylinder from the water inlet for heating; when the hot water is not used, the scraping ring falls to the lowest position inside the heat preservation cylinder under the influence of its own weight, and the second magnetic member generates a repulsive force with the first magnetic member to push the switch plate to flip and open the communication hole, and the hot water in the heating cylinder enters the heat preservation cylinder for storage; during the use of hot water, the hot water flows out through the water outlet, and the power component drives the scraping ring to move upward by means of the impact of the water flow. After the scraping ring rises, the second magnetic member moves out of the action range of the first magnetic member and loses the repulsive force on the switch plate, and the switch plate then rotates back to close the communication hole by relying on its own gravity, so as to prevent the water in the heating cylinder from continuing to flow into the heat preservation cylinder and prevent the water level in the heating cylinder from dropping and automatically replenishing water through the external water supply pipe, resulting in the water level temperature fluctuation in the heat preservation cylinder; at the same time, the scraping ring slides closely along the inner wall of the heat preservation cylinder during the up and down movement, and efficiently removes the scale attached to its surface; in summary, the water tank structure can not only prevent the automatic replenishment of cold water during the continuous use of hot water, but also significantly improve the water quality and maintain the good water storage and heat preservation performance of the heat preservation cylinder.

[0012] Optionally, the power component includes a rotating shaft, a paddle, a guiding pulley and a flexible traction member; the rotating shaft is rotatably connected to the cylinder wall of the heat preservation cylinder at the water outlet; the paddle is arranged on the rotating shaft; the guiding pulley is arranged at the top of the heat preservation cylinder; one end of the flexible traction member is connected to the scraping ring, and the other end extends to the rotating shaft after passing around the guiding pulley; when the paddle is impacted by the water flow, it can drive the rotating shaft to rotate and wind up the flexible traction member.

[0013] By adopting the above technical solution, when the water flows out of the water outlet, it can impact the paddle to rotate, thereby driving the rotating shaft to rotate and reel in the flexible traction member, realizing the stable lifting of the scraping ring. This design cleverly utilizes the water flow power, enabling the scraping ring to automatically rise during each water discharge process without additional energy, avoiding additional power input, achieving effective utilization of energy and improving the degree of automation; at the same time, the setting of the guiding pulley helps to reduce the frictional resistance of the flexible traction member during movement, further improving the transmission efficiency and system stability.

[0014] Optionally, the power assembly further includes a ratchet wheel, the ratchet wheel is arranged on the rotating shaft, and one end of the flexible traction member away from the scraping ring is fixed on the ratchet wheel; when the rotating shaft rotates, the ratchet wheel can reel in the flexible traction member, and when the scraping ring is lifted to the highest position, the ratchet wheel enters a slipping state.

[0015] By adopting the above technical solution, when the scraping ring rises driven by the power assembly, the ratchet wheel rotates with the rotating shaft to reel in the flexible traction member, effectively preventing the flexible traction member from loosening or winding, and ensuring the stable rise of the scraping ring. When the scraping ring is lifted to the highest position, the ratchet wheel enters a slipping state, avoiding overstretching the flexible traction member, thereby playing a limiting and protecting role for it, prolonging the service life of the flexible traction member and ensuring the reliable operation of the device.

[0016] Optionally, it further includes a water replenishing assembly, the water replenishing assembly includes a floating plate, a third magnetic member, a normally open control valve, and a control switch; a constant pressure hole for balancing the air pressure inside and outside the heat preservation cylinder is provided on the heat preservation cylinder; the floating plate is arranged inside the heat preservation cylinder and floats up and down with the water level; the third magnetic member is arranged on the floating plate; the normally open control valve is arranged at the water inlet; the control switch is arranged on the inner wall of the heat preservation cylinder and is electrically connected to the normally open control valve; when the floating plate is at the highest water level, it can trigger the control switch to close the normally open control valve; when the floating plate is at the lowest water level, the third magnetic member can generate a repulsive force with the first magnetic member to open the communication hole.

[0017] By adopting the above technical solution, the floating plate realizes automatic control of water replenishment as the water level in the heat preservation cylinder rises and falls, ensuring that the water levels in the heating cylinder and the heat preservation cylinder are maintained within a reasonable range; specifically, the constant pressure hole can ensure that the water flow can smoothly flow out of and into the heat preservation cylinder during water use and replenishment; during the water use process, when the floating plate reaches the lowest water level position, the repulsive force between the third magnetic part and the first magnetic part pushes the switch plate to flip, thereby opening the communication hole to achieve forced water replenishment, avoiding the water shortage problem caused by too low water level, and ensuring that the equipment can still operate normally and maintain water supply stability under extreme conditions; after stopping water use, the switch plate is opened, and the external water source is replenished into the heating cylinder, and the hot water in the heating cylinder is replenished into the heat preservation cylinder; when the water level in the heat preservation cylinder is replenished to the highest point, the floating plate triggers the control switch to control the normally open control valve to close the water inlet, accurately regulating the water levels in the heating cylinder and the heat preservation cylinder not to exceed the set upper limit, making the water replenishment process efficient and stable.

[0018] Optionally, the floating plate is located in the inner ring hole of the scraping ring; the water replenishment assembly further includes a limiting sliding rod, the limiting sliding rod extends along the sliding direction of the floating plate and is fixed in the heat preservation cylinder, the floating plate is slidably sleeved on the limiting sliding rod, and the limiting sliding rod can limit the floating plate from rotating in the horizontal direction.

[0019] By adopting the above technical solution, the floating plate can remain stable and does not interfere with the scraping ring during the up and down floating process in the water tank, and at the same time, it also avoids tilting or rotating due to water flow disturbance or external force, effectively preventing the floating plate from deviating from the normal movement track, thereby ensuring the accurate relative position between the third magnetic part and the first magnetic part, and ensuring the accurate and reliable opening action of the switch plate; improving the working stability and reliability of the entire water replenishment assembly.

[0020] Optionally, it further includes a magnetic shielding plate, and the magnetic shielding plate is arranged on the scraping ring and on the side of the second magnetic part close to the inner wall of the inner ring of the scraping ring.

[0021] By adopting the above technical solution, the magnetic shielding plate can effectively isolate the magnetic field interference between the second magnetic part and the third magnetic part; when the scraping ring and the floating plate move up and down along the inner wall of the heat preservation cylinder and the sliding rod respectively, it avoids unnecessary attraction due to the interaction of the magnetic parts between the two, thereby ensuring that the scraping ring and the floating plate run smoothly according to the predetermined track, without magnetic attraction interference or jamming phenomenon, and further ensuring the normal operation of the water flow control and descaling process inside the entire water tank.

[0022] Optionally, the water inlet is opened at the top end of the heating cylinder, and the communication hole and the water outlet are both opened at the bottom end of the heat preservation cylinder.

[0023] By adopting the above technical solution, the water inlet is opened at the top of the heating cylinder, which can ensure that cold water enters the heating cylinder from above, avoiding the direct impact of water flow on the heated water source at the bottom, thereby reducing the temperature fluctuation during the mixing process; the communication hole and the water outlet are both opened at the bottom end of the heat preservation cylinder, so that the heated water source can form a stable hot water layer at the bottom of the heat preservation cylinder, and the hot water flowing out is ensured to be of a relatively high temperature through bottom water discharge, further improving the constancy of the water temperature; this design effectively solves the problem of water temperature drop caused by cold and hot water mixing during continuous water use, and improves the user experience.

[0024] Optionally, a sliding groove is formed in the inner wall of the heat preservation cylinder along the sliding direction of the scraping ring, and a sliding block for slidingly cooperating with the sliding groove is provided on the scraping ring, and the sliding block is slidably arranged in the sliding groove to limit the scraping ring from rotating horizontally.

[0025] By adopting the above technical solution, the cooperation between the sliding groove and the sliding block can effectively limit the horizontal rotation of the scraping ring in the heat preservation cylinder, ensuring that the scraping ring only slides smoothly in the vertical direction. This design improves the stability of the movement of the scraping ring, avoids the problem of poor descaling effect caused by the inclination or jamming of the scraping ring, and thus more effectively removes the scale on the inner wall of the heat preservation cylinder, ensuring the normal operation and heat preservation efficiency of the water tank.

[0026] Optionally, a sealing ring is provided at the orifice of the communication hole, and the sealing ring is used to seal the gap when the switch plate covers the communication hole.

[0027] By adopting the above technical solution, the setting of the sealing ring effectively improves the sealing performance when the switch plate covers the communication hole, avoiding the problem of water leakage caused by poor sealing, thereby ensuring that the heated water source inside the heat preservation cylinder will not have unnecessary loss, and improving the reliability and stability of the entire water tank structure.

[0028] Optionally, a filter element is provided at the water outlet.

[0029] By adopting the above technical solution, the filter element can effectively filter the removed scale and impurities in the water during the water outlet process, thereby improving the purity of the outflowing water quality and avoiding the blockage or damage of subsequent water-using equipment caused by impurities flowing in.

[0030] In summary, the present application includes the following beneficial technical effects:

[0031] 1. It can improve the temperature constancy and heat preservation efficiency of the water tank during continuous water use and reduce the scale in the water tank. Specifically, the external water source enters the inner cavity of the heating cylinder for heating from the water inlet. When hot water is not in use, the scraping ring falls to the lowest position in the heat preservation cylinder under the influence of its own weight. After the second magnetic part generates a repulsive force with the first magnetic part, it pushes the switch plate to flip and open the communication hole, and the hot water in the heating cylinder enters the heat preservation cylinder for storage. During the process of using hot water, the hot water flows out through the water outlet, and the power assembly drives the scraping ring to move upward by means of the impact of the water flow. After the scraping ring rises, the second magnetic part moves out of the action range of the first magnetic part and loses the repulsive force on the switch plate. The switch plate then rotates back by its own gravity to close the communication hole, thus preventing the water in the heating cylinder from continuing to flow into the heat preservation cylinder and preventing the water level in the heating cylinder from dropping and automatically replenishing water through the external water supply pipe, which causes the water level temperature in the heat preservation cylinder to fluctuate. At the same time, during the up and down movement of the scraping ring, it slides closely along the inner wall of the heat preservation cylinder, efficiently removing the scale attached to its surface. To sum up, the water tank structure can not only prevent the automatic replenishment of cold water during the continuous use of hot water, but also significantly improve the water quality and maintain the good water storage and heat preservation performance of the heat preservation cylinder;

[0032] 2. When the water flows out of the water outlet, it can impact the paddle to rotate, and then drive the rotating shaft to rotate and wind up the flexible traction part, realizing the stable lifting of the scraping ring. This design makes clever use of the water flow power, enabling the scraping ring to automatically rise during each water outlet process without additional energy, avoiding additional power input, realizing the effective utilization of energy and improving the degree of automation. At the same time, the setting of the guiding pulley helps to reduce the frictional resistance of the flexible traction part during movement, further improving the transmission efficiency and system stability;

[0033] 3. The floating plate realizes automatic control of water replenishment as the water level in the heat preservation cylinder rises and falls, ensuring that the water levels in the heating cylinder and the heat preservation cylinder are maintained within a reasonable range. Specifically, the constant pressure hole can ensure that the water flow can smoothly flow out of and into the heat preservation cylinder during water use and water replenishment. During the water use process, when the floating plate reaches the lowest water level position, the repulsive force between the third magnetic part and the first magnetic part pushes the switch plate to flip, thus opening the communication hole to realize forced water replenishment, avoiding the water shortage problem caused by too low water level, and ensuring that the equipment can still operate normally and maintain the water supply stability under extreme conditions. After stopping using water, the switch plate opens, and the external water source is replenished into the heating cylinder, and the hot water in the heating cylinder is then replenished into the heat preservation cylinder. When the water level in the heat preservation cylinder is replenished to the highest point, the floating plate triggers the control switch to control the normally open control valve to close the water inlet, accurately regulating the water levels in the heating cylinder and the heat preservation cylinder not to exceed the set upper limit, making the water replenishment process efficient and stable.

[0043] Preferably, the water inlet 11 is provided at the top end of the heating cylinder 1, and the communication hole 21 and the water outlet 22 are both provided at the bottom end of the heat preservation cylinder 2; such a setting can avoid the water flow directly impacting the heated water source at the bottom during water replenishment, thereby reducing the temperature fluctuation during the mixing process. At the same time, it can also make the heated water source form a stable hot water layer at the bottom of the heat preservation cylinder 2, ensuring that the water flowing out from the water outlet 22 is all hot water at a relatively high temperature.

[0044] Preferably, a filter element 8 is provided at the water outlet 22, and the filter element 8 can effectively filter the scale and impurities in the water during the water outflow process, thereby improving the purity of the outflowing water quality.

[0045] Refer to Figure 1 and Figure 3 In this embodiment, the intercepting and descaling assembly 3 includes a scraping ring 31, a switch plate 32, a first magnetic member 33, and a second magnetic member 34; the scraping ring 31 is a circular metal ring, and its outer diameter matches the inner diameter of the heat preservation cylinder 2; the scraping ring 31 is made of high-strength titanium alloy, with light weight but high strength, and its edge is finely polished to reduce the frictional resistance; the scraping ring 31 is arranged in the inner cavity of the heat preservation cylinder 2, and the outer wall of the scraping ring 31 is in sliding contact with the inner wall of the heat preservation cylinder 2. The scraping ring 31 can slide up and down along the inner wall of the heat preservation cylinder 2 to scrape the scale on the inner wall of the heat preservation cylinder 2; a slider 311 whose shape matches the chute 24 is provided on each side of the scraping ring 31. The slider 311 is a protruding structure on the scraping ring 31, and the slider 311 is slidably arranged in the chute 24 to limit the scraping ring 31 to only slide along the extending direction of the chute 24 and not be able to rotate axially along the central axis of the scraping ring 31.

[0046] The switch plate 32 is a circular thin plate made of aluminum alloy. One end of the switch plate 32 is rotatably connected to the outer wall of the heat preservation cylinder 2 at the communication hole 21 through a hinge, and the rotation axis of the switch plate 32 is parallel to the horizontal plane. In the free state, the end of the switch plate 32 away from the hinge is vertically downward and can close the communication hole 21; both the first magnetic member 33 and the second magnetic member 34 are permanent magnets. The first magnetic member 33 is fixed on the side of the switch plate 32 close to the communication hole 21 and is arranged opposite to the first magnetic member 33. The second magnetic member 34 is fixed on the side of the scraping ring 31 close to the communication hole 21, and the magnetic poles of the opposite ends of the second magnetic member 34 and the first magnetic member 33 are the same; when the scraping ring 31 is at the lowest position in the heat preservation cylinder 2, the second magnetic member 34 can generate a repulsive force with the first magnetic member 33 and push the switch plate 32 to flip away from the communication hole 21 to open the communication hole 21; when the scraping ring 31 slides upward, the first magnetic member 33 gets out of the magnetic field range of the second magnetic member 34, and the switch plate 32 rotates back to its free state to close the communication hole 21.

[0047] Preferably, a sealing ring 7 is provided at the orifice of the communication hole 21. The sealing ring 7 can specifically be an O-shaped rubber sealing ring with a circular or rectangular cross-section; the sealing ring 7 can seal the gap between the switch plate 32 and the communication hole 21 when the switch plate 32 covers the communication hole 21, thereby enhancing the sealing performance.

[0048] In other embodiments, the scraping ring 31 can also be made of aluminum alloy, copper alloy, and composite materials; the shape of the scraping ring 31 can also be an annular member of other shapes or other materials that match the cross-sectional shape of the inner cavity of the heat preservation cylinder 2; the shape of the switch plate 32 can also be any other shape that can completely seal and cover the communication hole 21; the switch plate 32 can also be made of copper alloy or stainless steel.

[0049] Refer to Figure 1 and Figure 4 In this embodiment, the power assembly 4 can drive the scraping ring 31 to rise by using the water flow impact force when the water outlet 22 discharges water. The power assembly 4 includes a rotating shaft 41, a paddle 42, a guiding pulley 43, a flexible traction member 44, and a ratchet 45; the rotating shaft 41 is a short cylindrical shaft made of stainless steel, having high strength and corrosion resistance. The rotating shaft 41 is rotatably connected to the heat preservation cylinder 2 through a bearing seat 9 provided at the water outlet 22 of the heat preservation cylinder 2; the ratchet 45 can be a friction ratchet, and the ratchet 45 is fixed at one end of the rotating shaft 41 close to the inner cavity of the heat preservation cylinder 2 and rotates coaxially with the rotating shaft 41; a plurality of paddle blades 42 are provided, and the plurality of paddle blades 42 are circumferentially and equally spaced along the rotation axis of the rotating shaft 41 and fixed on the outer wall of the rotating shaft 41.

[0050] A plurality of guide pulleys 43 are also provided. The plurality of guide pulleys 43 are fixed on the inner wall of the heat preservation cylinder 2, and two guide pulleys 43 are fixed on both sides of the top end of the inner wall of the heat preservation cylinder 2; the flexible traction member 44 is a rope woven from high-strength nylon fibers, with sufficient flexibility and tensile resistance; the number of the flexible traction members 44 is two. The heads of the two flexible traction members 44 are respectively fixed on both sides of the scraping ring 31, and the ends of the two flexible traction members 44 respectively bypass the guide pulleys 43 corresponding to the top end and the side wall of one side of the heat preservation cylinder 2 and are then fixed to the ratchet wheel 45.

[0051] When the water flows out from the water outlet 22, it can impact the paddle 42 to rotate, and then drive the rotating shaft 41 to rotate and wind up the flexible traction member 44, so as to realize the stable lifting of the scraping ring 31. The design cleverly utilizes the water flow power, and the scraping ring 31 can be automatically lifted during each water outlet process without additional energy; and when the scraping ring 31 is lifted to the highest position, the paddle 42 continues to drive the rotating shaft 41 to rotate, and when the load torque of the ratchet wheel 45 exceeds the preset value, the ratchet wheel 45 enters the slipping state, avoiding excessive stretching of the flexible traction member 44, so as to play a limiting and protecting role for it. In other embodiments, the paddle 42 can be an integral structure with a plurality of blades; the number of the guide pulleys 43 and the flexible traction members 44 can both be one, and the flexible traction member 44 can also be a steel cable.

[0052] Referring to Figure 1 and Figure 2 , in this embodiment, the water replenishing assembly 5 includes a floating plate 51, a third magnetic member 52, a normally open control valve 53, a control switch 54 and a limiting slide rod 55; the floating plate 51 is a disc-shaped polystyrene foam board, the diameter of which is smaller than the inner diameter of the scraping ring 31. The floating plate 51 is arranged in the heat preservation cylinder 2 and floats on the water surface, floating up and down with the water level; the third magnetic member 52 is a permanent magnet, and the third magnetic member 52 is fixed on one side of the scraping ring 31 close to the communication hole 21 and is arranged opposite to the first magnetic member 33, and the magnetic poles of the opposite ends of the third magnetic member 52 and the first magnetic member 33 are the same; the normally open control valve 53 is arranged at the water inlet 11.

[0053] The control switch 54 is a travel switch, and the control switch 54 is fixed at the top end of the heat preservation cylinder 2 and is electrically connected to the normally open control valve 53; the trigger button of the control switch 54 can be triggered by being abutted by the floating plate 51 when the floating plate 51 rises to the highest water level; the limiting slide rod 55 is a cylindrical stainless steel rod, and two limiting slide rods 55 are provided. The two limiting slide rods 55 are vertically fixed in the heat preservation cylinder 2 and slide through the floating plate 51 to limit the floating plate 51, preventing the floating plate 51 from generating lateral displacement or inclination when floating up and down, so that the floating plate 51 can only rise and fall in the vertical direction; it should be emphasized that the water output from the water inlet 11 is greater than the water output from the water outlet 22 during water replenishment.

[0054] During the water usage process, when the floating plate 51 is at the lowest water level position in the heat preservation cylinder 2, the third magnetic member 52 can generate a repulsive force with the first magnetic member 33 and push the switch plate 32 to flip, thereby opening the communication hole 21. The water in the heating cylinder 1 is replenished into the heat preservation cylinder 2 through the communication hole 21, realizing forced water replenishment when the water level is too low during water usage. After stopping water usage, the switch plate 32 is opened, and external water source is replenished into the heating cylinder 1. The hot water in the heating cylinder 1 is then replenished into the heat preservation cylinder 2. When the water level in the heat preservation cylinder 2 is replenished to the highest point, the floating plate 51 triggers the control switch 54 to control the normally open control valve 53 to close the water inlet 11, accurately regulating the water levels in the heating cylinder 1 and the heat preservation cylinder 2 not to exceed the set upper limit. At the same time, the constant pressure hole 23 can ensure that the water can flow out of and into the heat preservation cylinder 2 smoothly during water usage and water replenishment.

[0055] Preferably, the water tank structure further includes a magnetic shielding plate 6, and the magnetic shielding plate 6 is arranged on the scraping ring 31 on the side of the second magnetic member 34 close to the inner wall of the scraping ring 31. In this way, the magnetic shielding plate 6 can effectively isolate the magnetic field interference between the second magnetic member 34 and the third magnetic member 52, ensuring that the scraping ring 31 and the floating plate 51 move smoothly along the predetermined trajectory during the lifting process without the phenomenon of magnetic attraction interference. In other embodiments, the floating plate 51 can also be a hollow stainless steel plate or a copper alloy plate that can float on the water surface; the material of the limiting slide rod 55 can also be aluminum alloy.

[0056] The implementation principle of a new water tank structure in an embodiment of this application is as follows: In the initial state, the self-weight of the scraping ring 31 causes the scraping ring 31 to be at the lowest position inside the heat preservation cylinder 2. At this time, a repulsive force is generated between the first magnetic member 33 and the second magnetic member 34. Under the action of the repulsive force, the switch plate 32 flips to open the communication hole 21, and the inner cavity of the heating cylinder 1 and the inner cavity of the heat preservation cylinder 2 are communicated. When using water, water flows out from the water outlet 22, and the water flow impacts the paddle 42 to drive the rotating shaft 41 and the ratchet 45 to rotate. The ratchet 45 winds up the flexible traction member 44 to make the scraping ring 31 rise smoothly along the direction perpendicular to the horizontal direction. In this way, the water flow power is ingeniously utilized, and without additional energy, the scraping ring 31 can automatically rise during each water outlet process to scrape the scale on the inner wall of the heat preservation cylinder 2. At the same time, after the scraping ring 31 rises, the repulsive force between the first magnetic member 33 and the second magnetic member 34 disappears, and the switch plate 32 flips under its own weight to close the communication hole 21, which prevents the external water source from being replenished into the heating cylinder 1 and the water in the heating cylinder 1 from being replenished into the heat preservation cylinder 2, ensuring that the water temperature of the water flowing out from the heat preservation cylinder 2 is constant when using water. When the water use stops, the scraping ring 31 falls back under its own weight. During the falling process of the scraping ring 31, the scale on the inner wall of the heat preservation cylinder 2 is further scraped. And when the scraping ring 31 falls to the lowest position, the repulsive force between the first magnetic member 33 and the second magnetic member 34 is restored. At this time, the switch plate 32 is opened, and the external water source can be smoothly replenished into the heating cylinder 1. In addition, during the water use process, when the floating plate 51 is at the lowest water level position inside the heat preservation cylinder 2, the third magnetic member 52 can generate a repulsive force with the first magnetic member 33 and push the switch plate 32 to flip to open the communication hole 21, and the water in the heating cylinder 1 is replenished into the heat preservation cylinder 2 from the communication hole 21, realizing forced water replenishment when the water level is too low during water use. When replenishing water after the water use stops, when the water level in the heat preservation cylinder 2 is replenished to the highest point, the floating plate 51 will trigger the control switch 54 to control the normally open control valve 53 to close the water inlet 11, precisely regulating the water levels of the heating cylinder 1 and the heat preservation cylinder 2 not to exceed the set upper limit.

[0057] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
