[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] like Figures 1-5As shown, a connector-type combined power filter with an indicator function includes a mounting base 1. A protective housing 11 is fixedly attached to the top of the mounting base 1, and multiple terminals 12 are fixedly attached to both ends of the protective housing 11. A circuit board 13 is fixedly attached to the top of the mounting base 1 and is located inside the protective housing 11. A heat-absorbing sheet A14 is fixedly attached inside the protective housing 11, and a heat-absorbing sheet B16 is fixedly attached to the end of the heat-absorbing sheet A14. The heat-absorbing sheet B16 is fixedly connected to the protective housing 11. The heat-absorbing sheets A14 and B16 are located close to the circuit board 13. Two heat dissipation fins 15 are fixedly attached to the inner walls of the heat-absorbing sheets A14 and B16 to dissipate heat outward. The heat-absorbing sheets A14 and B16 have a square structure. When the filter is working, the circuit board 13 will generate heat due to the current flowing through it. Due to the heat-absorbing sheets A14 and B16... Located close to the circuit board 13, and with heat absorber A14 and heat absorber B16 fixedly connected, and heat absorber B16 fixedly connected to the protective housing 11, the heat generated by the circuit board 13 is first transferred to heat absorber A14 and heat absorber B16. Then, the two heat dissipation fins 15 fixed to the inner walls of heat absorber A14 and heat absorber B16 increase the contact area with the air, quickly dissipating the heat on heat absorber A14 and heat absorber B16 outward. Due to the narrow hole shape of heat absorber A14 and heat absorber B16, the heat outflow inside can be accelerated. The cooperation of heat absorber A14, heat absorber B16 and heat dissipation fins 15 can efficiently absorb and dissipate the heat generated by the circuit board 13 during operation, preventing the circuit board 13 from being damaged due to overheating, ensuring the normal working performance and service life of the circuit board 13. The square structure of heat absorber A14 and heat absorber B16 can more fully cover the heat-generating area of the circuit board 13, improving the heat absorption effect.
[0027] like Figures 1-5As shown, a micro-pump 2 is installed on the inner wall of the heat absorber plate B16. An air inlet pipe 21 and an air blowing pipe 22 are fixedly connected to the side wall of the micro-pump 2. The air blowing pipe 22 is positioned near the heat absorber plate A14 and is used to accelerate the airflow within the heat absorber plate A14 and heat absorber plate B16. A temperature sensor 23 is installed on the outer wall of the heat absorber plate B16, positioned near the circuit board 13. Both the temperature sensor 23 and the micro-pump 2 are electrically connected to the circuit board 13. When the filter is working, the temperature sensor 23, being close to the circuit board 13, can monitor the temperature around the circuit board 13 in real time and transmit the temperature signal to the circuit board 13. When the monitored temperature exceeds a preset threshold, the circuit board 13 sends a start signal to the micro-pump 2. When the micro-air pump 2 starts working, the air inlet pipe 21 fixed to the side wall of the micro-air pump 2 draws in external air. After being pressurized by the micro-air pump 2, the airflow is blown towards the heat absorber A14 and heat absorber B16 through the air blowing pipe 22 located near the heat absorber A14, which accelerates the airflow speed in the heat absorber A14 and heat absorber B16, thereby accelerating heat dissipation. When the temperature sensor 23 detects that the temperature has dropped to a safe range, it will send a signal to the circuit board 13 again. The circuit board 13 controls the micro-air pump 2 to stop working. The linkage between the temperature sensor 23 and the micro-air pump 2 realizes the function of automatically controlling heat dissipation according to the temperature of the circuit board 13, avoiding energy waste, and at the same time, it can strengthen heat dissipation in time when the temperature is too high, further ensuring the safe operation of the circuit board 13.
[0028] like Figures 1-5 As shown, two elastic sheets 3 are fixedly connected to the end of the heat absorber plate B16. A frame 31 is fixedly connected to the top of the elastic sheets 3. A dust filter 32 is fixedly connected to the inner wall of the frame 31. The dust filter 32 is located near the side of the air inlet pipe 21. When the micro air pump 2 draws in external air through the air inlet pipe 21, because the dust filter 32 is located near the side of the air inlet pipe 21 and is fixed to the inner wall of the frame 31, and the frame 31 is fixed to the end of the heat absorber plate B16 through the elastic sheets 3, the external air will first be filtered by the dust filter 32 to remove dust, impurities, etc., before entering the air inlet pipe 21 and finally passing through the air inlet pipe 21. The air is blown through the air pipe 22 towards the heat absorber A14 and heat absorber B16. The elastic sheet 3 has a certain degree of elasticity. When a lot of dust accumulates on the dust filter 32 and needs to be cleaned, the elastic sheet 3 can be twisted to deform and complete the vibration cleaning. The dust filter 32 can effectively filter out dust and impurities in the air entering the filter, preventing dust from adhering to components such as the circuit board 13, heat absorber A14, heat absorber B16, and micro air pump 2, increasing the heat dissipation performance and working reliability of each component, and extending the service life of each component. The cooperation between the elastic sheet 3 and the frame 31 makes it easy for staff to clean the dust filter 32.
[0029] like Figures 1-5As shown, a connecting member 4 is fixedly connected to the end of the air blowing pipe 22, and multiple guide pipes 41 are fixedly connected to the middle of the connecting member 4. The air outlets of the guide pipes 41 are located at different angles within the heat absorber A14. The air blowing pipe 22, the connecting member 4, and the guide pipes 41 are interconnected. The airflow generated by the micro air pump 2 is delivered to the connecting member 4 through the air blowing pipe 22. Since the air blowing pipe 22, the connecting member 4, and the guide pipes 41 are interconnected, the airflow enters the connecting member 4 and is then discharged through the multiple guide pipes 41 fixedly connected to the middle of the connecting member 4. Because the air outlet of the guide tube 41 is located at different angles inside the heat absorber plate A14, the exhaust airflow can blow to various areas of the heat absorber plate A14 from different directions, more comprehensively covering the heat-generating parts of the heat absorber plate A14, accelerating the airflow in various areas inside the heat absorber plate A14. The setting of multiple guide tubes 41 at different angles allows the airflow to act on the heat absorber plate A14 more evenly and comprehensively, avoiding the problem of insufficient local heat dissipation of the heat absorber plate A14 caused by blowing air in one direction, and significantly improving the heat dissipation efficiency of the heat absorber plate A14.
[0030] like Figures 1-5 As shown, a heat insulation plate is fixed to the inner wall of the heat-absorbing sheet B16, and the heat insulation plate is set near both sides of the micro air pump 2. The heat insulation plate fixed to the inner wall of the heat-absorbing sheet B16 is set near both sides of the micro air pump 2. When the heat-absorbing sheet B16 absorbs the heat transferred by the circuit board 13, the heat insulation plate can prevent the heat on the heat-absorbing sheet B16 from being transferred to both sides of the micro air pump 2. The setting of the heat insulation plate effectively isolates the heat of the heat-absorbing sheet B16 from being transferred to the micro air pump 2, and avoids the micro air pump 2 from experiencing performance degradation or damage due to long-term exposure to high temperature environment.
[0031] like Figures 1-5 As shown, the air blowing pipe 22 has a spherical structure. The spherical air blowing pipe 22 is fixedly connected to the side wall of the micro air pump 2. When the micro air pump 2 generates airflow and delivers it to the air blowing pipe 22, the internal space of the spherical air blowing pipe 22 is relatively large and evenly distributed, which enables the airflow to flow more smoothly in the air blowing pipe 22. The spherical air blowing pipe 22 is conducive to the smooth transmission of airflow and reduces the energy loss during the airflow transmission process.
[0032] Working principle: When the filter is working, the circuit board 13 generates heat due to the current flowing through it. Since heat absorbers A14 and B16 are located close to the circuit board 13, and heat absorbers A14 and B16 are fixedly connected, while heat absorber B16 is fixedly connected to the protective housing 11, the heat generated by the circuit board 13 is first transferred to heat absorbers A14 and B16. Then, the two heat dissipation fins 15 fixed to the inner walls of heat absorbers A14 and B16 increase their contact area with the air, quickly dissipating the heat from heat absorbers A14 and B16 outwards. Furthermore, the narrow orifice shape of heat absorbers A14 and B16 accelerates the outflow of heat. When the filter is working, the temperature sensor 23, being close to the circuit board 13... The device can monitor the temperature around the circuit board 13 in real time and transmit the temperature signal to the circuit board 13. When the monitored temperature exceeds a preset threshold, the circuit board 13 sends a start signal to the micro-pump 2, and the micro-pump 2 starts working. The air inlet pipe 21 fixed to the side wall of the micro-pump 2 draws in external air. After being pressurized by the micro-pump 2, the airflow is blown towards the heat absorber A14 and heat absorber B16 through the air blowing pipe 22 set near the heat absorber A14, which accelerates the airflow speed in the heat absorber A14 and heat absorber B16, thereby accelerating heat dissipation. When the temperature sensor 23 detects that the temperature has dropped to a safe range, it sends a signal to the circuit board 13 again, and the circuit board 13 controls the micro-pump 2 to stop working. When the micro-pump 2 draws in external air through the air inlet pipe 21, the air is then blown by the air pump 2. The dust filter 32 is positioned near the air inlet pipe 21 and is fixed to the inner wall of the frame 31. The frame 31 is then fixed to the end of the heat absorber plate B16 via an elastic sheet 3. External air is first filtered by the dust filter 32 to remove dust and impurities before entering the air inlet pipe 21. Finally, it is blown onto the heat absorber plate A14 and heat absorber plate B16 through the air blowing pipe 22. The elastic sheet 3 has a certain degree of elasticity. When a lot of dust accumulates on the dust filter 32 and needs to be cleaned, the elastic sheet 3 can be twisted to deform it and complete the vibration cleaning. The airflow generated by the micro air pump 2 is delivered to the connecting member 4 through the air blowing pipe 22. Since the air blowing pipe 22, the connecting member 4, and the guide pipe 41 are interconnected, the airflow enters the connecting member 4 and then passes through multiple guide pipes fixed in the middle of the connecting member 4. The air is discharged from the guide tube 41. Since the air outlet of the guide tube 41 is located at different angles inside the heat absorber plate A14, the discharged air can blow to various areas of the heat absorber plate A14 from different directions, more comprehensively covering the heat-generating parts of the heat absorber plate A14 and accelerating the airflow in various areas inside the heat absorber plate A14. The heat insulation plate fixed to the inner wall of the heat absorber plate B16 is set close to both sides of the micro air pump 2. When the heat absorber plate B16 absorbs the heat transferred by the circuit board 13, the heat insulation plate can prevent the heat on the heat absorber plate B16 from being transferred to both sides of the micro air pump 2. The spherical blowing pipe 22 is fixed to the side wall of the micro air pump 2. When the micro air pump 2 generates airflow and delivers it to the blowing pipe 22, the internal space of the spherical blowing pipe 22 is relatively large and evenly distributed, which can make the airflow flow more smoothly inside the blowing pipe 22.
