DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 5 As shown, an automatic regulating temperature control valve for a heating pipe according to an embodiment of the present invention comprises a valve body 1, a water outlet 11 is arranged on one side of the valve body 1, a water inlet 12 is arranged on the other side of the valve body 1, a lifting mechanism 13 is installed on the top of the valve body 1, a water guide hole 15 is arranged inside the valve body 1, a valve core 14 is fixed on the bottom end of the output rod of the lifting mechanism 13, the valve core 14 is inserted inside the water guide hole 15, and the outer diameter of the valve core 14 matches the inner diameter of the water guide hole 15, a temperature sensor 2 is installed on the side of the valve body 1 close to the water outlet 11, a probe 21 is fixed on the bottom end of the temperature sensor 2, a connecting arm 3 is fixed on the side of the valve core 14 close to the water outlet 11, a connecting shell 32 is fixed on the side of the connecting arm 3 away from the valve core 14, a cleaning brush 31 is arranged inside the connecting shell 32, the connecting shell 32 is arranged below the probe 21, and the connecting shell 32 can be sleeved on the outside of the probe 21; When the heater is used, the water for heating is heated and then transported through the heating pipe. The hot water is transported to the radiator through the heating pipe, and the heat can be dissipated to the outside through the radiator. At this time, hot water will continue to flow inside the heating pipe to achieve real-time heating. However, after a period of heating, the temperature inside the room will reach a preset temperature. At this time, in order to maintain the temperature, the temperature needs to be adjusted by the temperature control valve. When in use, the water inlet end 12 is connected to the water outlet of the heating pipe, and the water outlet end 11 is connected to the water inlet of the heating pipe. During use, hot water enters the interior of the valve body 1 through the water inlet end 12, and then is output to the water guide hole 15. The inside of the water outlet 11 can realize the circulation of hot water inside the valve body 1. At this time, the valve core 14 and the water guide hole 15 are in a completely separated state. The hot water enters the water outlet 11 and mixes with the original water flow inside it. Since the heat of the original water flow evaporates through the radiator, the inside will cool down, which will cause the hot water to mix and cool down after entering the water outlet 11. In this process, the temperature sensor 2 measures the temperature of the hot water circulating inside the water outlet 11 in real time, and cooperates with the indoor thermometer to detect the current indoor temperature. When the indoor temperature reaches the preset maximum value, the lifting mechanism 13 is started to push the valve core 14 downward. At this time, the valve core 14 is inside the water guide hole 15. The water outlet of the water guide hole 15 is reduced by the valve core 14, which can reduce the output speed of the water guide hole 15. At this time, the water flow inside the water outlet end 11 becomes smaller. At this time, the original water flow is driven to slow down, and the proportion of the original water flow is larger. At the same time, the temperature inside the water outlet end 11 will decrease accordingly. At this time, the speed at which the probe 21 of the temperature sensor 2 contacts the water flow decreases. The probe 21 will be inserted into the inside of the water outlet end 11 during use. At this time, the outside of the probe 21 is easily wrapped by impurities and dirt. Therefore, the connecting arm 3 is fixed on one side of the valve core 14, and the connecting arm 3 is driven when the lifting mechanism 13 drives the valve core 14 to rise and fall to adjust the water flow. The arm 3 is raised and lowered synchronously, and at this time the connecting arm 3 drives the connecting shell 32 to rise and fall on the outside of the probe 21, and the connecting shell 32 synchronously drives the cleaning brush 31 to rise and fall, so that the cleaning brush 31 can brush the outside of the probe 21, so that the impurities and dirt on the outside of the probe 21 can be swept off, and the outside of the probe 21 can be kept clean, which can prevent the impurities and dirt from affecting the temperature measurement of the probe 21. By controlling the water flow entering the water outlet 11, the mixing ratio of hot water and the original water flow can be controlled. The larger the hot water flow, the smaller the proportion of the original water flow, and the higher the temperature at this time, the smaller the hot water flow, the larger the proportion of the original water flow, and the temperature will decrease at this time.

[0024] like Figures 1 to 5 As shown, the connection shell 32 is rotatably connected to a gear ring 311, and multiple groups of cleaning brushes 31 are evenly spaced inside the gear ring 311. The multiple groups of cleaning brushes 31 are fixedly connected to the gear ring 311, and a rotating assembly is provided on one side of the gear ring 311 close to the connection arm 3; When the cleaning brush 31 cleans the probe 21, the rotating assembly drives the gear ring 311 to rotate, and the gear ring 311 drives the cleaning brush 31 to clean the outside of the probe 21. At this time, the cleaning brush 31 can rotate during the process of raising and lowering the connecting shell 32. The rotation can drive the cleaning brush 31 to rotate and sweep the outside of the probe 21. When multiple groups of cleaning brushes 31 are sweeping, they cover the outside of the probe 21. By rotating and sweeping the same area of ​​the probe 21 multiple times, impurities and dirt on the outside of the probe 21 are more easily cleaned and removed.

[0025] like Figures 1 to 5 As shown, the rotating assembly includes a transmission gear 321 meshingly connected to the gear ring 311 near the connecting arm 3, the transmission gear 321 is rotatably connected to the inside of the connecting shell 32, an impeller 33 is arranged below the connecting shell 32, and the bottom end of the impeller 33 is rotatably connected to the valve body 1; During use, hot water enters the water outlet 11 through the water guide hole 15. The hot water circulation will push the impeller 33 to rotate, and the impeller 33 drives the transmission gear 321 to rotate. The transmission gear 321 can drive the gear ring 311 to rotate synchronously, so that the cleaning brush 31 can continue to rotate and clean the water outlet 11 during the circulation of hot water inside the water outlet 11.

[0026] like Figures 1 to 5 As shown, a transmission rod 331 is fixed to the top of the impeller 33, and a transmission hole 322 is opened inside the transmission gear 321. The transmission rod 331 is slidably connected inside the transmission hole 322, and the top of the transmission rod 331 is rotatably connected to the valve body 1; During the rotation of the impeller 33, the blades of the impeller 33 cannot rise with the connecting shell 32, and the blades of the impeller 33 will interfere with the probe 21. Therefore, the impeller 33 is set to rotate in a fixed position. When the connecting arm 3 drives the connecting shell 32 to rise, the transmission gear 321 will slide on the outside of the transmission rod 331 through the transmission hole 322. At this time, the impeller 33 can drive the transmission rod 331 to rotate. When the transmission rod 331 rotates, it drives the transmission gear 321 to rotate through the transmission hole 322. At this time, the impeller 33 can maintain its original position while driving the transmission gear 321 to rotate, which can prevent the rotation of the impeller 33 from interfering with the probe 21.

[0027] like Figures 1 to 5 As shown, the inclination angle of the impeller 33 blades is consistent with the inclination angle of the cleaning brush 31 inside the gear ring 311, and the inclination directions of the impeller 33 and the cleaning brush 31 are consistent; When the impeller 33 is driven by the water flow to rotate, the impeller 33 rotates in the counterclockwise direction. At this time, the transmission gear 321 will drive the gear ring 311 to rotate in the clockwise direction. At this time, the cleaning brush 31 sweeps the surface of the probe 21 in a clockwise direction. During the sweeping process, since the direction of the cleaning brush 31 has an inclined angle, the dirt swept by the brush can be discharged to the bottom of the connecting shell 32. At this time, it is easier for the cleaning brush 31 to clean the dirt and impurities on the outside of the probe 21.

[0028] like Figures 1 to 7 As shown, the bottom end of the valve core 14 is rotatably connected to a connecting frame 43, and a plurality of scrapers 41 are rotatably connected to the inside of the connecting frame 43 at equal intervals. A rotating drum 42 is arranged below the connecting frame 43, and the bottom end of the rotating drum 42 is rotatably connected to the valve body 1. A plurality of rotating plates 4 are arranged outside the rotating drum 42, and the outer side of the scraper 41 is tightly attached to the inner side of the water guide hole 15. During use, hot water will flow through the water guide hole 15. However, impurities and dirt are likely to remain at the inlet and outlet of the water guide hole 15 during the circulation process. Since the inner wall of the pipe needs to be welded during the production and processing, metal debris is likely to splash inside the pipe during the welding process. Part of the metal debris is wrapped in the impurities and dirt, resulting in friction between the surfaces of the valve core 14 and the water guide hole 15 and the metal debris each time the valve core 14 is raised and lowered in the water guide hole 15, which may easily cause damage to the valve core 14 and the water guide hole 15. At this time, a gap will appear between the valve core 14 and the water guide hole 15. To prevent this problem, a rotating plate 4 is arranged below the water guide hole 15. When water flows into the water inlet end 12, the rotating plate 4 is driven to rotate, and the rotating plate 4 drives the rotating drum 42 to rotate, and the rotating drum 42 drives the connecting frame 43 to rotate. At this time, the connecting frame 43 can drive the scraper 41 to scrape the inner wall of the water guide hole 15. The scraper 41 can scrape off the impurities and dirt attached to the inner wall of the water guide hole 15 to prevent the metal debris contained in the dirt from damaging the valve core 14 and the water guide hole 15. At the same time, the connecting frame 43 can rise and fall synchronously with the valve core 14, so as to clean the inside of the water guide hole 15 more comprehensively.

[0029] like Figures 1 to 9 As shown, a rotating column 431 is fixed at the bottom end of the connecting frame 43, and the bottom end of the rotating column 431 is inserted into the inside of the rotating drum 42. A plurality of transmission grooves 432 are evenly spaced on the outside of the rotating column 431, and a plurality of sliders 422 are evenly spaced and fixed at the top end of the inside of the rotating drum 42. The sliders 422 are slidably connected to the inside of the transmission grooves 432. During the rotation of the rotating drum 42, the connecting frame 43 will be driven to rotate through the rotating column 431. When the rotating drum 42 rotates, the slider 422 will be driven to rotate. At this time, the slider 422 can drive the rotating column 431 to rotate through the transmission groove 432. The rotating column 431 can drive the connecting frame 43 to rotate. When the valve core 14 rises and falls at the same time, it will drive the connecting frame 43. The connecting frame 43 pulls the rotating column 431, and the slider 422 can slide inside the transmission groove 432. At this time, the rotating column 431 can be driven by the rotating drum 42 during the lifting process.

[0030] like Figures 1 to 11 As shown, a connecting shaft 442 is fixed to the middle of the rotating plate 4, and the connecting shaft 442 is rotatably connected to the inside of the rotating drum 42. A rotating block 44 is fixed to the end of the connecting shaft 442 close to the rotating drum 42, and the rotating block 44 is arranged inside the rotating drum 42. A second coil spring 441 is fixed to the outside of the connecting shaft 442 close to one end of the rotating block 44, and the other end of the second coil spring 441 is fixedly connected to the rotating drum 42. A receiving groove 433 is provided between two adjacent transmission grooves 432, and the rotating block 44 can be slidably connected to the inside of the receiving groove 433. A guide groove 434 is provided on one side of the receiving groove 433 close to the protrusion of the rotating block 44. During use, when the gap between the valve core 14 and the water guide hole 15 is small, the water flow rate is also small, the water flow rate is accelerated but the amount of water flowing is reduced. At this time, the water flow rate is not enough to drive the rotation of the rotating plate 4, and the rotating plate 4 will affect the water flow rate. Therefore, a rotating block 44 is provided. When the rotating column 431 is inserted halfway into the rotating cylinder 42, the edge of the guide groove 434 will contact the upper surface of the rotating block 44. At this time, the rotating block 44 will be pushed, and at the same time, the rotating block 44 slides into the interior of the guide groove 434 and the receiving groove 433, and the second coil spring 441 is squeezed. At this time, the rotating plate 4 remains as Fig.10 The rotating plate 4 is in a vertical state at this time. When water flows through the position of the rotating plate 4 and is input into the water guide hole 15, the resistance of the rotating plate 4 in this state is small, which can reduce the obstruction to the water flow; When the valve core 14 moves upward and drives the connecting frame 43 to rise, the gap between the valve core 14 and the water guide hole 15 gradually increases. After the connecting frame 43 drives the rotating column 431 to extend halfway out of the inside of the rotating drum 42, the receiving groove 433 and the guide groove 434 are separated from the rotating block 44. The elastic force of the second coil spring 441 will drive the connecting shaft 442 to reset, and the connecting shaft 442 drives the rotating plate 4 to reset. At this time, the rotating plate 4 is at an inclined angle of 30°. At this time, the flow of hot water flowing inside the water guide hole 15 is relatively large. At this time, the water flow pushes the rotating plate 4 to drive the rotating drum 42 so that the scraper 41 can scrape the dirt inside the water guide hole 15. When the valve core 14 drives the connecting frame 43 to descend, the rotating plate 4 can be rotated to a vertical state again.

[0031] like Figures 1 to 11As shown, multiple groups of limit blocks 421 are evenly spaced outside the rotating drum 42 to match the number of the rotating plates 4, and each group of limit blocks 421 is provided with two, and each group of two limit blocks 421 surrounds the outer side of the connecting shaft 442; When the second coil spring 441 drives the connecting shaft 442 to reset, the connecting shaft 442 can drive the rotating plate 4 to rotate 30°. At this time, the rotating plate 4 may over-rotate, which will cause the rotating plate 4 to have too much resistance to the water flow, affecting the normal flow of hot water. Therefore, a limit block 421 is provided to limit the maximum rotation angle of the rotating plate 4, which can prevent the rotating plate 4 from rotating too much.

[0032] like Figures 1 to 8 As shown, a rotating groove 413 is provided inside the rotating drum 42, and a rotating shaft 412 is fixed to the top and bottom ends of the scraper 41, and the rotating shaft 412 is rotatably connected to the inside of the rotating groove 413, and a first coil spring 411 is fixed to the outside of the rotating shaft 412, and the other end of the first coil spring 411 is fixedly connected to the inner side of the rotating groove 413; When the scraper 41 is scraping the inner wall of the water guide hole 15, the elastic force of the first coil spring 411 will drive the rotating shaft 412, and the rotating shaft 412 will drive the scraper 41 to rotate toward the inner wall of the water guide hole 15. At this time, the scraper 41 can be close to the inner wall of the water guide hole 15. At the same time, the rotating plate 4 is pushed by the water flow and drives the scraper 41 to rotate clockwise through the connecting frame 43. At this time, the protrusion of the scraper 41 will be dragged. When the scraper 41 is in contact with the inner wall of the water guide hole 15 for a long time, it will be worn due to friction. At this time, the elastic force of the first coil spring 411 can drive the scraper 41 to continue to be close to the inner wall of the water guide hole 15 to maintain the cleaning effect of the scraper 41.
