[0104] The detachable connection methods include but are not limited to: plug-in connection, snap connection, threaded connection, etc.;
[0105] When water is heated, water vapor is generated above the water surface. The water vapor moves upward with kinetic potential energy, which can drive the blades or electric heating elements to rotate; when water is heated, the air in the water moves upward to overflow the water surface, and the air in the water appears as bubbles before overflowing the water surface.

[0107] Example 1
[0108] Figure 1-Figure 2 This is a schematic diagram of the structure of Example 1.
[0109] like Figure 1 , Figure 2 This embodiment provides a heating device 1000 for boiling water, and the heating device 1000 includes:
[0110] Container 1, used for holding water;
[0111] The electric heating element 2 is arranged in the container 1 and is used to heat the water in the container 1;
[0112] The rotating shaft 3 is rotatably arranged relative to the container 1;
[0113] The blade 4 is arranged on the rotating shaft 3, and the angle between at least a part of the blade 4 and the axis of the rotating shaft 3 is an obtuse angle or an acute angle, and the blade 4 is arranged so that the water vapor generated by the water being heated can drive the blade 4 to rotate;
[0114] The electric heating element 2 is connected to the rotating shaft 3 .
[0115] The rotating shaft 3 is rotatably arranged relative to the container 1, and the blades 4 are arranged on the rotating shaft 3, so that the rotation of the rotating shaft 3 can drive the blades 4 to rotate, or the rotation of the blades 4 can drive the rotating shaft 3 to rotate. The angle between at least part of the blades 4 and the axis of the rotating shaft 3 is an obtuse angle or an acute angle, that is, it is neither parallel nor perpendicular, so that this part of the blades 4 is subjected to the force of water vapor and has a tangential force component to drive the blades 4 to rotate. The electric heating element 2 is connected to the rotating shaft 3, and the rotation of the blades 4 and the rotating shaft 3 can drive the electric heating element 2 to rotate, avoiding the deposition of scale on the surface of the electric heating element 2, thereby reducing the scaling on the surface of the electric heating element 2, and can improve the heating efficiency of the electric heating element 2, and can reduce the risk of dry burning of the electric heating element 2, thereby improving safety.
[0116] The operation process of the heating device 1000 is as follows: power is supplied to the electric heating element 2, so that the electric heating element 2 generates heat to heat the water in the container 1. The water is heated to generate water vapor. During the upward movement of the water vapor, it acts on the surface of the blade 4, driving the blade 4 to rotate. The blade 4 drives the rotating shaft 3 and the electric heating element 2 to rotate. On the one hand, the rotation of the rotating shaft 3 and the electric heating element 2 can stir the water in the container 1 to avoid scale deposition; on the other hand, the rotation of the electric heating element 2 can further avoid scale deposition on the surface of the electric heating element 2; therefore, scaling on the surface of the electric heating element 2 can be prevented.
[0117] By using water vapor as a power source to drive the blades 4, the shaft 3 and the electric heating element 2 to rotate, on the one hand, no additional power source is required, and the structure is simple and compact; on the other hand, the effect of water vapor can be used to improve energy utilization.
[0118] like Figure 2, the rotating shaft 3 is rotatably connected to the bottom wall of the container 1. In other embodiments, the rotating shaft 3 can be rotatably connected to both the top wall and the bottom wall of the container 1 to improve stability. The heating device 1000 also includes a conductive member, which is arranged at the bottom of the container 1 and is electrically connected to the electric heating member 2 through the rotating shaft 3. The rotating shaft 3 is installed at the bottom of the container 1 to facilitate the electrical connection between the electric heating member 2 and the conductive member led out from the bottom of the container 1. The two ends of the conductive member are the lead-out end and the connecting end, the lead-out end is connected to the power supply, and the connecting end is electrically connected to the electric heating member 2. In order to facilitate the lead-out end to follow the rotating shaft 3 and the electric heating member 2 to rotate to prevent winding, the lead-out end can be electrically connected to the power supply by contact, for example, by a rotating joint. Regarding how to realize the rotatable connection between the lead-out end of the conductive member and the power supply, the specifics can refer to the prior art. In order to ensure the waterproof sealing inside the electric heating member 2, a sealing ring or other sealing member can be correspondingly arranged at the electrical connection position. In other embodiments, the electric heating member 2 can be installed on the blade 4.
[0119] like Figure 2 The rotating shaft 3 extends in the vertical direction. On the one hand, it makes the arrangement of the blades 4, the electric heating element 2 and the rotating shaft 3 simple and compact. On the other hand, the extending direction of the rotating shaft 3 is consistent with the moving direction of the water vapor, which facilitates the upward movement of the water vapor to drive the blades 4 to rotate.
[0120] like Figure 2 The electric heating element 2 is installed at the middle and lower part of the rotating shaft 3, so as to lower the lowest water level that submerges the electric heating element 2. Specifically, in this embodiment, there are two electric heating elements 2, which are fixed on both sides of the rotating shaft 3 by brackets 31. In other embodiments, the electric heating element 2 and the rotating shaft 3 can be detachably connected, so as to facilitate the removal of the electric heating element 2 and the cleaning and maintenance of the container 1, the blades 4, the rotating shaft 3, the electric heating element 2, etc. in the heating device 1000.
[0121] like Figure 2 The blade 4 is installed on the upper part of the rotating shaft 3 so as to be staggered with the electric heating element 2, so as to facilitate installation. The blade 4 is detachably installed on the rotating shaft 3, so that the blade 4 can be easily removed to clean and maintain the container 1, the blade 4, the rotating shaft 3, the electric heating element 2, etc. in the heating device 1000. In this embodiment, the blade 4 is specifically spiral-shaped, with a simple structure and low procurement cost; the number of blades 4 is multiple, and the multiple blades 4 are evenly distributed around the rotating shaft 3.
[0122] In other embodiments, the position of the blade 4 can be adjusted so that the blade 4 is located at a lower position in the container 1 so that it can be submerged in water. When the water is heated and tumbles, the blade 4 can be driven to rotate, or when the water is heated, the bubbles in the water move upward to drive the blade 4 to rotate.
[0123] like Figure 1 A connection port 11 is provided on the surface of the container 1 to facilitate the transportation of hot water and / or water vapor in the container 1.
[0124] As shown in the figure, the heating device 1000 also includes an intelligent control module 71, an alarm 72 and a sensor 73. The sensor 73 is used to detect the water level signal in the container 1 and send it to the intelligent control module 71. The intelligent control module 71 controls the alarm 72 according to the water level signal. When the water level is lower than the preset water level, the alarm 72 is controlled to send a warning signal to improve the safety of the operation of the heating device 1000.
[0125] The notch on one side of the container 1 where the intelligent control module 71 is arranged is used to install glass so as to observe the water level in the container 1 .

[0128] Container 1, refer to Example 1;
[0129] The rotating shaft 3 is rotatably arranged relative to the container 1;
[0130] The electric heating element 2 is arranged in the container 1 and connected to the rotating shaft 3 for heating water. The angle between at least part of the electric heating element 2 and the axis of the rotating shaft 3 is an obtuse angle or an acute angle, and the electric heating element 2 is arranged so that the water rolls when heated or bubbles are generated when heated, which can drive the electric heating element 2 to rotate.
[0131] The rotating shaft 3 is arranged to rotate, and the electric heating element 2 is arranged on the rotating shaft 3, so that the rotation of the rotating shaft 3 can drive the electric heating element 2 to rotate, or the rotation of the electric heating element 2 can drive the rotating shaft 3 to rotate. The angle between at least part of the electric heating element 2 and the axis of the rotating shaft 3 is an obtuse angle or an acute angle, that is, it is neither parallel nor perpendicular, so that this part of the electric heating element 2 is subjected to the force of water rolling or bubbles and has a tangential force component to drive the electric heating element 2 and the rotating shaft 3 to rotate. The rotation of the electric heating element 2 can prevent scale from being deposited on the surface of the electric heating element 2, thereby reducing scaling on the surface of the electric heating element 2, improving the heating efficiency of the electric heating element 2, and reducing the risk of dry burning of the electric heating element 2, thereby improving safety.
[0132] The operation process of the heating device 1000 is as follows: power is supplied to the electric heating element 2, so that the electric heating element 2 generates heat to heat the water in the container 1. The water is heated so that the bubbles in the water move upward, acting on the surface of the electric heating element 2, driving the electric heating element 2 to rotate. When the bubble movement intensifies, the water in the container 1 begins to roll, and the rolling of the water drives the electric heating element 2 and the rotating shaft 3 to rotate faster. The electric heating element 2 drives the rotating shaft 3 to rotate together. On the one hand, the rotation of the rotating shaft 3 and the electric heating element 2 can stir the water in the container 1 to prevent scale deposition; on the other hand, the rotation of the electric heating element 2 can further prevent scale from being deposited on the surface of the electric heating element 2; therefore, scaling on the surface of the electric heating element 2 can be prevented.
[0133] The rotating shaft 3 and the electric heating element 2 are driven to rotate by using the tumbling of heated water or the bubbles generated by the heated water as a power source. On the one hand, no additional power source is required, and the structure is simple and compact. On the other hand, the energy utilization rate can be improved by utilizing the effect of the tumbling of water or the bubbles s.

On the one hand, the arrangement of the electric heating element 2 and the rotating shaft 3 is simple and compact. On the other hand, the extending direction of the rotating shaft 3 is consistent with the movement direction of the water bubble, which facilitates the upward movement of the water bubble to drive the electric heating element 2 to rotate.
[0135] like Figure 3 , the electric heating element 2 is installed in the middle and lower part of the rotating shaft 3, which is convenient for lowering the lowest water level line that submerges the electric heating element 2. A bracket 31 is provided on the rotating shaft 3, and the electric heating element 2 is connected to the rotating shaft 3 through the bracket 31. Specifically, the number of electric heating elements 2 in this embodiment is four, which are evenly spaced around the rotating shaft 3 and fixed to the rotating shaft 3 through the bracket 31. In other embodiments, the electric heating element 2 can be detachably installed on the rotating shaft 3, which is convenient for removing the electric heating element 2 and cleaning and maintaining the container 1, blades 4, rotating shaft 3, electric heating element 2, etc. in the heating device 1000.
[0136] The spiral structure is easy to rotate under the action of fluid, such as Figure 4 The electric heating element 2 is spiral-shaped, so that it can rotate under the action of air bubble movement or water tumbling in the water.
[0137] like Figure 3 , Figure 5 The heating device 1000 further includes a sliding member 51 and a guide member 52. The guide member 52 is fixedly arranged relative to the container 1. The sliding member 51 is slidably mounted on the guide member 52. The sliding member 51 is used to slide along the electric heating member 2 and scrape the surface of the electric heating member 2. The electric heating member 2 is spiral, so that when the electric heating member 2 rotates, the sliding member 51 can slide along the surface of the electric heating member 2 to scrape off the scale deposited on the surface of the electric heating member 2, further reducing the scaling on the surface of the electric heating member 2.
[0138] Specifically, in this embodiment, the guide member 52 is a slide groove, which has a simple and compact structure. In other embodiments, the guide member 52 may also be a slide rail. Figure 5 The heating device 1000 further includes a connecting block 55, which is fixedly connected to the sliding member 51, and the connecting block 55 is T-shaped, and both ends of the T-shaped head are installed in the slide groove. The connecting block 55 is arranged so that the sliding member 51 is indirectly installed on the guide member 52, which can increase the distance between the sliding member 51 and the guide member 52, so that the sliding member 51 contacts the electric heating member 2 and avoids interference with other structures such as the electric heating member 2 and the guide member 52.
[0139] like Figure 3 The extension direction of the rotating shaft 3 is along the vertical direction, the electric heating element 2 is specifically in a spiral shape spiraling around the rotating shaft 3, and the extension direction of the guide member 52 is parallel to the rotating shaft 3. Such an arrangement makes the structure of the heating device 1000 simple and compact.
[0140] like Figure 5 The sliding member 51 is provided with a receiving groove 511, which penetrates both ends of the sliding member 51 in the sliding direction, that is, the upper end and the lower end of the receiving groove 511 penetrate, so that the electric heating element 2 can pass through the receiving groove 511 from both ends, so that the sliding member 51 can slide along the surface of the electric heating element 2. The receiving groove 511 is provided with an avoidance opening 512 on one side of the sliding direction of the sliding member 51, and one side can be the front side, the rear side, the left side, the right side, etc., so that the electric heating element 2 can extend out of the receiving groove 511 from the avoidance opening 512.
[0141] like Figure 5 The heating device 1000 also includes an elastic member 53, one end of the elastic member 53 is connected to the container 1, and the other end is connected to the sliding member 51. The two ends of the sliding path of the sliding member 51 are respectively the first end (upper end) and the second end (lower end). The elastic member 53 is used to reset the sliding member 51 from the second end to the first end. The elastic member 53 is arranged to reset the sliding member 51, so that the sliding member 51 can slide repeatedly on the surface of the electric heating member 2 to remove scale, and further improve the descaling effect of the electric heating member 2. Specifically, the elastic member 53 is a spring, which is arranged in the slide groove, one end is fixed above the slide groove, and the other end is fixed on the connecting block 55 to be indirectly connected to the sliding member 51. A stabilizing rod 56 is arranged in the slide groove, which is specifically a cylindrical rod. The elastic member 53 is sleeved on the stabilizing rod 56, which can constrain the deformation direction of the elastic member 53 and improve the sliding stability of the sliding member 51.
[0142] like Figure 5The heating device 1000 further includes a stopper 54 disposed on the sliding member 51. In the direction from the first end to the second end, the sliding member 51 and the stopper 54 are disposed in sequence, that is, the sliding member 51 is disposed above the stopper 54. At the first end, the stopper 54 is located in the rotation space of the electric heating member 2. The stopper 54 can contact the electric heating member 2 and be driven by the electric heating member 2, so that the sliding member 51 can slide along the surface of the electric heating member 2.
[0143] The movement process of the sliding member 51 in this embodiment is as follows:
[0144] The sliding member 51 is generally located at the first end, that is, the upper end of the slide groove. At this time, the height of the sliding member 51 is higher than the height of the electric heating member 2, so that the sliding member 51 is located outside the rotation space of the electric heating member 2, and the height of the stopper 54 coincides with the height of the electric heating member 2, so that the stopper 54 is located in the rotation space of the electric heating member 2;
[0145] The water generates bubbles or rolls when heated, driving the four electric heating elements 2 to rotate, so that one of the electric heating elements 2 rotates to the stopper 54 and contacts the stopper 54. Because the electric heating element 2 is spiral, the electric heating element 2 continues to rotate so that the electric heating element 2 passes through the receiving groove 511, and drives the stopper 54 and the sliding element 51 to slide downward along the slide groove. The sliding element 51 can scrape the surface of the electric heating element 2 during the downward sliding process to remove the scale on the surface of the electric heating element 2, until the sliding element 51 slides downward to the lower end of the slide groove, the electric heating element 2 is separated from the receiving groove 511 and continues to rotate, and the sliding element 51 and the stopper 54 are reset from the lower end of the slide groove to the upper end of the slide groove under the action of the elastic element 53;
[0146] The four electric heating elements 2 continue to rotate, so that the next electric heating element 2 rotates to the stopper 54 to drive the stopper 54 and the sliding element 51 to slide from the upper end to the lower end of the slide groove to scrape the surface of the next electric heating element 2.
[0147] like Figure 3 The heating device 1000 also includes blades 4, which are arranged on the rotating shaft 3. The angle between at least part of the blades 4 and the axis of the rotating shaft 3 is an obtuse angle or an acute angle, and the blades 4 are arranged so that the water tumbles when heated, the water generates bubbles when heated, or the water generates water vapor when heated, which can drive the blades 4 to rotate. The blades 4 are arranged on the rotating shaft 3, and the rotation of the blades 4 can drive the rotating shaft 3 and the electric heating element 2 on the rotating shaft 3 to rotate. The blades 4 can enhance the power of the rotating shaft 3 and the electric heating element 2 to rotate, and further reduce scaling on the surface of the electric heating element 2. The blades 4 are arranged above the rotating shaft 3. Even if the water level drops, the blades 4 can use the water vapor to drive the electric heating element 2 to rotate. Specifically, the blades 4 are spiral.

[0149] Example 3
[0150] Figure 6-Figure 8 This is a schematic diagram of the structure of Example 3.
[0151] like Figure 6 , Figure 7 This embodiment provides a heating device 1000 for boiling water, and the heating device 1000 includes:
[0152] Container 1, referring to Example 1;
[0153] An electric heating element 2, arranged in the container 1, for heating water;
[0154] The rotating shaft 3 is rotatably arranged relative to the electric heating element 2;
[0155] The blade 4 is arranged on the rotating shaft 3, and the angle between at least a part of the blade 4 and the axis of the rotating shaft 3 is an obtuse angle or an acute angle, and the blade 4 is arranged so that the water vapor generated by the water being heated can drive the blade 4 to rotate;
[0156] The descaling member 6 is arranged on the rotating shaft 3 and is used for scraping the surface of the electric heating member 2 .
[0157] The rotating shaft 3 is rotatably arranged relative to the container 1, and the blades 4 are arranged on the rotating shaft 3, so that the rotation of the rotating shaft 3 can drive the blades 4 to rotate, or the rotation of the blades 4 can drive the rotating shaft 3 to rotate. At least part of the blades 4 form an obtuse angle or an acute angle with the axis of the rotating shaft 3, that is, they are neither parallel nor perpendicular, so that this part of the blades 4 is subjected to the force of water vapor and has a tangential force component to drive the blades 4 to rotate. The descaling member 6 is arranged on the rotating shaft 3 and can rotate with the rotating shaft 3 to scrape the surface of the electric heating member 2, reduce scaling on the surface of the electric heating member 2, improve the heating efficiency of the electric heating member 2, reduce the risk of dry burning of the electric heating member 2, and thus improve safety.
[0158] The operation process of the heating device 1000 is as follows: the electric heating element 2 is powered on, so that the electric heating element 2 generates heat to heat the water in the container 1, and the water is heated to generate water vapor. During the upward movement of the water vapor, it acts on the surface of the blade 4, driving the blade 4 to rotate, and the blade 4 drives the rotating shaft 3 and the descaling element 6 to rotate, so that the descaling element 6 scrapes the surface of the electric heating element 2. On the one hand, the rotation of the rotating shaft 3 and the descaling element 6 can stir the water in the container 1 to prevent scale deposition; on the other hand, the rotation of the descaling element 6 to scrape the surface of the electric heating element 2 can further prevent scale from being deposited on the surface of the electric heating element 2; therefore, scaling on the surface of the electric heating element 2 can be prevented.
[0159] By using water vapor as a power source to drive the blades 4, the rotating shaft 3 and the descaling member 6 to rotate, no additional power source is required, the structure is simple and compact, and the energy utilization rate can be improved. In other embodiments, the position of the blades 4 can be adjusted so that the blades 4 are located at a lower position in the container 1 so that they can be submerged by water, and the water can drive the blades 4 to rotate when heated and rolled, or the bubbles in the water can drive the blades 4 to rotate when heated.
[0160] Specifically, the electric heating element 2 is fixed on the bottom wall of the container 1 , and the rotating shaft 3 is rotatably connected to the top wall and the bottom wall of the container 1 .
[0161] like Figure 6 , Figure 7 The rotating shaft 3 is sleeved on the electric heating element 2, and the descaling element 6 is arranged on the inner side of the rotating shaft 3, so that the structure is simple and compact. Specifically, the rotating shaft 3 is provided with a plurality of grooves penetrating the inner surface and the outer surface of the rotating shaft 3, so that the electric heating element 2 can contact with water, and the inner side of the electric heating element 2 is provided with a plurality of descaling elements 6, and the descaling elements 6 and the grooves are arranged at intervals. In other embodiments, the descaling element 6 can be installed on the blade 4.
[0162] In this embodiment, the blades 4 are specifically spiral-shaped, with a simple structure and low procurement cost; there are multiple blades 4, and the multiple blades 4 are evenly distributed around the rotating shaft 3.
[0163] For other structures in this embodiment, refer to Embodiment 1 and other embodiments.
[0164] like Figure 8 The container 1 is provided with a water inlet 12, and the heating device 1000 further includes an electric telescopic rod 81, a rectangular block 82 and a cylindrical plug 83. The electric telescopic rod 81 drives the rectangular block 82 and the cylindrical plug 83 to move, so that the cylindrical plug 83 opens the water inlet 12 or closes the water inlet 12. In other embodiments, a manual switch valve or an automatic control valve can be provided to control the opening and closing of the water inlet 12.
[0165] Example 4
[0166] Fig. 9 This is a schematic diagram of the structure of Example 4.
[0167] This embodiment provides a heating device 1000 for boiling water, and the heating device 1000 includes:
[0168] Container 1, referring to Example 1;
[0169] An electric heating element 2, arranged in the container 1, for heating water;
[0170] The descaling component 6 is slidably mounted on the electric heating component 2, and the descaling component 6 is configured such that the tumbling of water or the generation of bubbles by the heating of water can drive the descaling component 6 to slide.
[0171] The operation process of the heating device 1000 is as follows: the electric heating element 2 is powered on, so that the electric heating element 2 generates heat to heat the water in the container 1. The water generates bubbles or rolls when heated, which can drive the descaling element 6 to slide along the surface of the electric heating element 2, scrape the surface of the electric heating element 2, reduce the scale on the surface of the electric heating element 2, improve the heating efficiency of the electric heating element 2, reduce the risk of dry burning of the electric heating element 2, and improve safety. The water rolls when heated or the bubbles generated when heated are used as a power source to drive the descaling element 6 to slide, without the need to set up an additional power source, the structure is simple and compact, and the energy utilization rate can be improved.
[0172] Specifically, the electric heating element 2 is fixed on the bottom wall of the container 1. The heating part of the electric heating element 2 is located in the middle and upper part of the electric heating element 2, so that the water in the middle and upper part of the container 1 can boil first, and then the water below the unboiled water drives the water inside the container 1 to roll up and down, so as to drive the descaling element 6 to slide up and down to scrape the surface of the electric heating element 2.
[0173] In this embodiment, the electric heating element 2 extends in the vertical direction, so that the structure is simple and compact. The descaling element 6 is specifically a spiral sheet spirally wound around the extension direction of the electric heating element 2.
[0174] The maximum drainage volume of the descaling member 6 refers to the drainage volume when the descaling member 6 is just submerged in water. The ratio of the weight of the descaling member 6 to the maximum drainage volume is greater than the density of water, that is, when the descaling member 6 is placed in water, the gravity of the descaling member 6 is greater than the buoyancy, and the descaling member 6 will sink. In other embodiments, the upper size of the descaling member 6 can be set to be larger than the lower size, so as to increase the buoyancy effect on the descaling member 6, so that the descaling member 6 slides upward along the surface of the electric heating member 2, and then slides downward under the action of gravity, forming a reciprocating slide, thereby improving the scraping effect on the surface of the electric heating member 2.
