Energy-saving intelligent switching power supply

Abstract

This invention discloses an energy-saving intelligent switching power supply, including a stabilizing component, a cooling component fixedly installed inside the stabilizing component, and a sealing component fixedly installed on the surface of the stabilizing component. By setting the sealing component, the invention allows a second fixed plate to move downwards via the retraction of an electric telescopic rod, enabling a driving device connected to the surface of the second fixed plate to move synchronously. At this time, the driving device drives rotating rods on both sides of the second fixed plate to rotate, causing threaded rods connected to one end of each rotating rod to rotate synchronously. Therefore, two second movable plates mounted on the surfaces of the two threaded rods can move towards or away from each other. When the two second movable plates move towards each other, they can drive two sets of sealing pads to be installed on the left and right sides of the switching power supply body respectively, sealing the connection port. This prevents dust from entering the interior of the switching power supply body through the connection port, thereby improving the practicality of the device.

Description

Technical Field

[0001] This invention relates to the field of switching power supply technology, and more specifically, to an energy-saving intelligent switching power supply. Background Technology

[0002] A switching power supply is a type of power supply that uses modern power electronics technology to control the on and off time ratio of the switching transistors to maintain a stable output voltage. It mainly consists of four parts: the main circuit, the control circuit, the detection circuit, and the auxiliary power supply, and also includes the core circuit board.

[0003] Existing switching power supplies all have corresponding power connection ports on their surface. Since switching power supplies are usually placed directly on a table when not in use, the power connection ports are exposed to the air for a long time. Therefore, when the switching power supply is idle for a long time, dust can easily accumulate at the power connection ports. Dust enters the switching power supply through the power connection ports and adheres to the surface of the core circuit board, thus affecting the normal operation of the circuit board. In addition, after the switching power supply has been used for a long time, the electrical components inside the machine will generate a certain temperature. Sustained high temperature will shorten the life of electrical components and eventually cause the switching power supply to malfunction.

[0004] Therefore, based on the inventor's extensive experience in design, development and actual manufacturing in the relevant industry over many years, the inventor has researched and improved the existing structure and its shortcomings, and provided an energy-saving intelligent switching power supply, in order to achieve better protection of the power interface from dust and facilitate heat dissipation. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide an energy-saving intelligent switching power supply. By incorporating a stabilizing component, the present invention not only stabilizes the main body of the switching power supply during operation but also assists in cooling the bottom surface of the main body, thereby improving the practicality of the device. Furthermore, by incorporating a cooling component, the present invention utilizes a circulating water source to lower the operating temperature of the main body of the switching power supply, reducing water consumption and extending the lifespan of the internal electrical components, thus further enhancing the practicality of the device. Finally, by incorporating a sealing component, when the two second movable plates move towards each other, two sets of sealing pads can be installed on the left and right sides of the main body of the switching power supply to seal the connection port, thus preventing dust from entering the interior of the main body through the connection port, thereby improving the practicality of the device and solving the problems mentioned in the background art.

[0011] In a preferred embodiment, the fixing component includes a second spring, one end of which is fixedly connected to a movable tube, and one end of the movable tube is fixedly mounted with a connecting block. The surface of the connecting block is provided with an insertion groove, and a fixing block is fixedly mounted inside the insertion groove. An mounting plate is fixedly mounted on the surface of the fixing block.

[0012] In a preferred embodiment, there are four first movable plates, the top surface of each first movable plate is fixedly connected to the bottom surface of the mounting box, the bottom surface of each of the four first movable plates is fixedly connected to one end of each of the four first springs, the top surface of the rubber pad is in contact with the bottom surface of the mounting box, the size of the through groove is adapted to the size of the adsorption plate, and the surface of the base is fixedly connected to the bottom end of the support tube.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. This invention incorporates a stabilizing component. When the main body of the switching power supply is subjected to an external impact, the mounting box moves further downward, breaking the balance and eliminating the gap between the adsorption plate and the groove. The fan's force draws away the remaining air between the adsorption plate and the groove, causing the mounting box to move further downward. This further downward movement allows the mounting box to actively move away from the point of impact, thus preventing further impact. When the fan can no longer draw air, the airflow sensor switch in the air inlet section is triggered, activating a delay switch. The delay switch causes the fan to first turn off after a delay, and then turn on after a delay. After the delay, the device returns to a dynamically stable state. Therefore, this invention not only stabilizes the main body of the switching power supply during operation but also assists in cooling the bottom surface of the main body, thereby improving the practicality of the device.

[0018] 2. This invention, by setting up a cooling component, first adds water to the water storage tank, then uses an electric water pump to extract the water from the tank and transmits it to the water supply pipe through a connecting pipe. After entering the water supply pipe, the water is added to the interior of the water storage column, ultimately reducing the surface temperature of the cooling plate. Therefore, when the cooling plate is in close contact with the surface of the switching power supply body, it can cool it down. Thus, the circulating water source can be used to reduce the temperature of the switching power supply body during operation, which can reduce water consumption and extend the service life of the electrical components inside the switching power supply body, thereby improving the practicality of the device.

[0019] 3. This invention, by setting up a sealing component, uses the retraction of an electric telescopic rod to move the second fixed plate downwards, allowing the driving device connected to the surface of the second fixed plate to move synchronously, thus moving it to the top surface of the mounting box. At this time, the elastic action of the second spring drives the movable tube to move inwards to the side of the mounting box, causing the mounting plate to be installed on the surface of the mounting vertical plate for limiting and fixing. At this time, the driving device drives the rotating rods on both sides to rotate, so that the threaded rods connected to one end of the rotating rods can rotate synchronously. Therefore, the two second movable plates installed on the surfaces of the two threaded rods can move towards or away from each other. When the two second movable plates move towards each other, they can drive two sets of sealing pads to be installed on the left and right sides of the switching power supply body respectively to seal the connection port. Therefore, it can prevent dust from entering the interior of the switching power supply body through the connection port, thereby improving the practicality of the device.

The top surface of the first fixing plate 31 is in contact with the bottom surface of the second fixing plate 33. The bottom surface of the driving device 34 is in contact with the top surface of the mounting box 19. There are six sealing gaskets 311, which are divided into two groups. The two groups of sealing gaskets 311 are respectively movably installed on the left and right sides of the switching power supply body 4. The bottom surface of the mounting vertical plate 37 is connected to the mounting box 19. The top surfaces of the two springs are in contact with each other.

The surface of the movable tube 382 is movably connected to the inside of the side of the mounting box 19.

Through the structure of the sealing gasket 311, it can be installed in the power connection port opened on the surface of the switching power supply body 4 under the movement of the horizontal plate 310 to seal it and prevent dust from entering the interior of the switching power supply body 4 through the power connection port when idle, so as to ensure that the electrical components can operate normally.

[0033] Working principle of the invention: First, the overall weight of the device presses down on the adsorption plate 14, and at the same time, the fan 15 is started. When the fan 15 starts, it draws suction through the second ventilation pipe 17, the first ventilation pipe 13, and the adsorption plate 14. At this time, there is still a gap between the adsorption plate 14 and the groove. Due to the wind force of the fan 14 and the reaction force of the first spring 113 and the rubber pad 116, they are in a dynamic stable state. When the main body of the switching power supply 4 is impacted by an external force, the mounting box 19 moves further down, breaking the balance. After this, the gap between the adsorption plate 14 and the groove disappears, and the fan 15... 5. The wind force draws out the remaining air between the adsorption plate 14 and the groove, causing the mounting box 19 to move further downward. This further downward movement allows the mounting box 19 to actively move away from the point of impact, thus preventing further impact on the mounting box 19. When the fan 15 can no longer draw in any air, the wind force sensor switch of the air inlet section is triggered, activating the delay switch. The delay switch causes the fan 15 to first turn off after a delay, and then turn on after a delay. After the delay, the device returns to a dynamic stable state. First, water is added to the water storage tank 21, and the electric water pump 23 pumps the water into the storage tank. Water is drawn from water tank 21 and transmitted to water pipe 25 through connecting pipe 24. After entering water pipe 25, the water is added to the interior of water storage column 26, ultimately reducing the surface temperature of cooling plate 27. Therefore, cooling plate 27 can cool the surface of switching power supply body 4 when it is in close contact with it. The retraction of electric telescopic rod 32 drives the second fixing plate 33 to move downward, so that the drive device 34 connected to the surface of the second fixing plate 33 can move synchronously, thus moving downward to the top surface of mounting box 19. At this time, the elastic action of second spring 381 drives movable pipe 382 towards mounting box 19. The internal movement of the side causes the mounting plate 386 to be installed on the surface of the mounting vertical plate 37 for limiting and fixing. At this time, the drive device 34 drives the rotating rods 35 on both sides to rotate, so that when the rotating rods 35 rotate, the threaded rods 36 connected to one end can rotate synchronously. Therefore, the two second movable plates 39 installed on the surfaces of the two threaded rods 36 can move towards each other or away from each other. When the two second movable plates 39 move towards each other, they can drive the two sets of sealing gaskets 311 to be installed on the left and right sides of the switching power supply body 4 respectively to seal the electrical ports.
