Description

Technical Field

[0001] The present invention relates to the technical field of inductors, and in particular to an inductor with increased inductance. Background Art

[0002] Inductors are essential components in the power electronics field. Flat-wire, vertically wound, combined magnetic circuit inductors are widely adopted due to their advantages, including low parasitic capacitance, automated winding, and excellent electromagnetic compatibility in circuit applications. Existing flat-wire, vertically wound, combined magnetic circuit inductors typically consist of two yokes and two center legs forming a square-shaped core. The vertically wound flat-wire coil is sheathed around the two legs, resulting in a larger coil than the yoke, leaving some unused space. However, in current applications, the desire is to maximize the inductance of an inductor of the same size.

[0003] Prior art document CN119419042A provides an inductor in which the yoke of the inductor is arranged on one side of the first magnetic core in a third direction. The magnetic paths between the yoke and the first magnetic core, and between the yoke and the second magnetic core, are both conducted through the end yokes. The first and second magnetic cores are arranged along a first direction perpendicular to the third direction. This reduces the width of the inductor in the first direction, i.e., the width of the inductor, making the overall inductor more compact and better suited for applications requiring a smaller inductor width. Furthermore, the side-mounted yoke increases the magnetic flux area within a limited space.

[0004] Existing inductors generate static electricity during operation, especially in high-frequency or high-voltage applications. This static electricity can attract dust particles in the air, causing them to accumulate on the surface of the inductor's coils. Existing technologies lack automated cleaning and maintenance technology for inductor coils. The core function of an inductor relies on the magnetic field coupling formed by the coils and the magnetic core. Dust accumulation on the coil surface disrupts the magnetic field distribution and weakens the magnetic coupling efficiency between the coils and the core.

[0005] In summary, the prior art lacks a technology for automatically cleaning and maintaining the coils of inductors. Summary of the Invention

[0011] Preferably, a guide air duct is fixedly connected through the middle of the movable seat, the bottom end of the guide air duct is slidingly matched with the inner wall of the air guide sleeve, the top end of the guide air duct is fixedly connected with a bellows, the other end of the bellows is fixedly connected with the bottom end of the baffle cover, and the outer wall of the guide air duct is slidingly matched with the inner wall of the annular guide groove.

[0012] Preferably, a hydraulic rod is fixedly connected to the fixed frame, the other end of the hydraulic rod is fixedly connected to the movable frame, and a ball head rod is fixedly connected to the fixed frame.

[0013] Preferably, a universal joint is provided on the movable frame for rotation connection, a driving wheel is fixedly connected to one end of the universal joint, a direction-changing rod is fixedly connected to the other end of the universal joint, a spiral groove is provided on the outer wall of the direction-changing rod, and the inner wall of the spiral groove is slidingly matched with the outer wall of the ball head rod.

[0014] Preferably, one end of the baffle plate passes through the movable frame and is fixedly connected to a driven wheel, and the driven wheel is meshed with the driving wheel for transmission. A slotted tube is fixedly connected to the inner wall of one side of the baffle plate, and the bottom end of the baffle plate is a hollow structure, and the inner wall of the bottom end of the baffle plate is connected to the corrugated tube.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

At the same time, under the action of the annular rack B, the sponge ring on the rotating shaft rotates, ensuring that the sponge ring cleans every part of the coil, improving cleaning efficiency. The automated cleaning system significantly reduces dependence on manual cleaning and reduces the human resources and time required for maintenance. The clean coil can keep the inductance value and other electrical parameters of the inductor within the design range, ensuring stable electrical performance. 2. By setting up an exhaust sleeve, while the transmission mechanism drives the coil maintenance mechanism to rotate, it can drive the exhaust plate in the exhaust sleeve to move back and forth. Cooperating with the guide air duct, it can generate suction force in the shield, so that the dust generated by the coil maintenance mechanism is collected and processed, avoiding dust from re-deposition and ensuring that the coil remains clean, thereby achieving multiple advantages such as efficient cleaning, environmental friendliness, and convenient maintenance; 3. By setting a direction-changing rod on the mobile frame, when the hydraulic rod drives the mobile frame to move, it can drive the erected shield and coil cleaning and maintenance mechanism away from the coil and automatically level it. During the use of the inductor, by keeping a safe distance between the cleaning and maintenance mechanism and the coil, the maintenance work can be relatively independent of the production operation, reducing potential interference with other functional components of the inductor, thereby reducing the failure rate.

An exhaust plate 603 is slidably mounted on the inner wall of the exhaust sleeve 6. One end of the exhaust plate 603 passes through the inner wall of the exhaust sleeve 6 and extends to the outside. When the motor 701 drives the drive wheel 703 to rotate, it also drives the transmission wheel 702 to rotate, allowing the transmission wheel 702 to rotate the L-shaped rod 705 connected to the adjustment wheel 704. At this time, the L-shaped rod 705 drives the exhaust plate 603 to move back and forth rapidly via the connecting rod 706. Both the output pipe 601 and the air guide sleeve 602 are installed with a one-way valve.

[0023] like Figure 5 As shown, the transmission mechanism 7 includes a motor 701, which is fixedly connected to the adjustment seat 5.

[0024] like Figure 6 As shown, a guide air pipe 801 is fixedly connected to the middle of the movable seat 8, and the bottom end of the guide air pipe 801 is slidably matched with the inner wall of the air guide sleeve 602.

[0025] like Figure 7 As shown, a hydraulic rod 901 is fixedly connected to the fixed frame 9 , and the other end of the hydraulic rod 901 is fixedly connected to the movable frame 10 . A ball head rod 902 is fixedly connected to the fixed frame 9 .

[0026] like Figure 7 As shown, a universal joint 1001 is rotatably connected to the mobile frame 10, and a driving wheel 1002 is fixedly connected to one end of the universal joint 1001. A direction-changing rod 1003 is fixedly connected to the other end of the universal joint 1001. A spiral groove 1004 is provided on the outer wall of the direction-changing rod 1003. The inner wall of the spiral groove 1004 is slidably matched with the outer wall of the ball rod 902. The hydraulic rod 901 is used to drive the connected mobile frame 10 to move. At this time, the mobile frame 10 will drive the shield 11 to approach the coil 3. At the same time, under the action of the ball rod 902, the direction-changing rod 1003 with the spiral groove 1004 will rotate, so that the direction-changing rod 1003 drives the driving wheel 1002 connected to the direction-changing rod 1003 to rotate. At this time, the driving wheel 1002 drives the shield 11 connected to the driven wheel 1101 to rotate and stand up.

[0027] like Figure 8 As shown, one end of the baffle 11 passes through the movable frame 10 and is fixedly connected to a driven wheel 1101, which is engaged with the driving wheel 1002 for transmission. A slotted tube 1102 is fixedly connected to the inner wall of one side of the baffle 11, and the bottom end of the baffle 11 is a hollow structure, and the inner wall of the bottom end of the baffle 11 is connected to the bellows 802.

[0028] like Figure 8 As shown, the coil maintenance mechanism 12 includes a rotating shaft 1201, which is rotatably connected to the inner wall of the baffle 11, and a plurality of sponge rings 1202 are fixedly connected to the outer wall of the rotating shaft 1201. The sponge rings 1202 are in sliding contact with the outer wall of the coil 3, and a gear 1203 is fixedly connected to the bottom end of the rotating shaft 1201, and the gear 1203 is meshed with the annular rack B104 for transmission.

[0029] By setting up the coil maintenance mechanism 12, when the coil 3 on the inductor needs to be cleaned and maintained, the transmission mechanism 7 can be used to drive the coil maintenance mechanism 12 to rotate around the coil 3. At the same time, under the action of the annular rack B104, the sponge ring 1202 on the rotating shaft 1201 rotates, which can ensure that the sponge ring 1202 cleans every part of the coil 3, thereby improving the cleaning efficiency. The automated cleaning system significantly reduces the dependence on manual cleaning and reduces the human resources and time required for maintenance. The cleaned coil 3 can keep the inductance value and other electrical parameters of the inductor within the design range, ensuring stable electrical performance.

[0030] Working principle: When the coil 3 needs to be cleaned and maintained, the hydraulic rod 901 is used to drive the connected mobile frame 10 to move. At this time, the mobile frame 10 will drive the shield 11 to approach the coil 3. At the same time, under the action of the ball head rod 902, the direction-changing rod 1003 with a spiral groove 1004 will rotate, so that the direction-changing rod 1003 drives the driving wheel 1002 connected to the direction-changing rod 1003 to rotate. At this time, the driving wheel 1002 will drive the shield 11 connected to the driven wheel 1101 to rotate and stand up, so that the sponge ring 1202 can contact the coil 3. Then, the motor 701 is used to drive the connected driving wheel 703 to rotate. At this time, the driving wheel 703 will mesh with the annular rack A103, thereby driving the adjusting seat 5 to rotate, so that the coil maintenance mechanism 12 rotates around the coil 3. At this time, under the action of the annular guide groove 105, the movable seat 8 connected to the guide air guide tube 801 will slide on the adjusting seat 5, so that the sponge ring 1202 is always attached to the coil 3. At this time, under the action of the annular rack B104, the meshing gear 1203 will rotate, and then the gear 1203 will drive the connected rotating shaft 1201 to rotate, so that the rotating shaft 1201 drives multiple sponge rings 1202 to rotate, so as to clean and maintain the coil 3; Then, when the motor 701 drives the driving wheel 703 to rotate, it will also drive the transmission wheel 702 to rotate, so that the transmission wheel 702 can drive the L-shaped rod 705 connected to the adjusting wheel 704 to rotate. At this time, the L-shaped rod 705 will drive the exhaust plate 603 to move back and forth rapidly through the connecting rod 706, thereby generating negative pressure in the exhaust sleeve 6, so that the dust generated during the cleaning and maintenance of the sponge ring 1202 is drawn into the exhaust sleeve 6 through the slotted tube 1102, the bellows 802, the guide air pipe 801 and the air sleeve 602 in turn, and is injected into the air guide cavity 101 through the output pipe 601 and discharged through the exhaust pipe 102. After cleaning and maintaining the coil 3, the hydraulic rod 901 is used to drive the shield 11 to move away and lay flat.
