[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] As attached Figure 1-2 As shown, this embodiment provides a low noise inductor, including

[0037] Reactor body 10;

[0038] The bottom plate 20 is located at the bottom of the reactor body 10 and is used to support the reactor body 10. The bottom plate 20 is a rectangular structure.

[0039] like Figure 3 As shown, mounting holes 211 are symmetrically formed at both ends of the first side edge 21 of the bottom plate 20. Figure 1 As shown, a first buffer 30 is disposed in the mounting hole 211 , and a second buffer 40 is disposed on the second side 22 parallel to the first side 21 . At least part of the first buffer 30 and the second buffer 40 are located between the bottom plate 20 and the ground.

[0040] In the present technical solution, the provision of the first buffer member 30 and the second buffer member 40 can balance the weight inside the reactor product and ensure the stability of the product, and can effectively reduce the operating noise of the product, extend the service life, and avoid malfunctions.

[0041] Continue to see Figure 3The third side 23 and the fourth side 24 of the bottom plate 20 are perpendicular to the first side 21. A mounting hole 211 near the third side 23 has a notch 212 facing the outside of the third side 23, and another mounting hole 211 near the fourth side 24 has another notch 212 facing the outside of the fourth side 24. The two notches 212 are mirror-imaged, and the first buffer member 30 is disposed in the mounting hole 211 and covers the notch 212, which will not damage the overall appearance of the product.

[0042] The notch 212 is trumpet-shaped. The notch 212 near the third side 23 has a width that gradually decreases from the third side 23 to the mounting hole 211. The notch 212 near the fourth side 24 has a width that gradually decreases from the fourth side 24 to the mounting hole 211. The central axis of the notch 212 passes through the center of the mounting hole 211. The width of the notch 212 near the mounting hole 211 is smaller than the diameter of the mounting hole 211, which can prevent the first buffer component 30 from detaching from the mounting hole 211 through the notch 212.

[0043] like Figure 4-Figure 7 As shown, the first buffer member 30 is an "I"-shaped structure, including a horizontally arranged top buffer plate 31, a bottom buffer plate 32, and a vertical annular hollow connecting rib 33 located between the top buffer plate 31 and the bottom buffer plate 32. The top buffer plate 31 and the bottom buffer plate 32 are square plates. In this embodiment, the connecting rib 33 enters the mounting hole 211 through the notch 212. The top buffer plate 31 is located above the bottom plate 20, and the bottom buffer plate 32 is located at the bottom of the bottom plate 20, which can effectively isolate the vibration transmitted from the bottom plate 20 to the ground and reduce noise.

[0044] Continue to see Figure 5 , Figure 7 A through hole 34 is respectively opened in the center of the bottom buffer plate 32 and the top buffer plate 31, and the inner diameter of the through hole 34 is the same as the inner diameter of the connecting rib 33; the outer diameter of the connecting rib 33 is adapted to the inner diameter of the mounting hole 211, and the outer diameter of the connecting rib 33 is larger than the width of the notch 212 at the mounting hole 211, that is, the outer diameter of the connecting rib is larger than the minimum width of the notch 212, so as to prevent the connecting rib 33 of the first buffer member 30 from being separated from the bottom plate during use and losing the buffering effect on the reactor.

[0045] See also Figure 6 The minimum distance from the outer wall of the connecting rib 33 to each side of the top buffer plate 31 or the bottom buffer plate 32 is equal, and is less than or equal to the shortest distance from the notch 212 to the third side 23 or the fourth side 24. When the first buffer member 30 is placed in the mounting hole 211, the bottom buffer plate 32 or the top buffer plate 31 will not exceed the edge position of the reactor bottom plate 20, avoiding occupying excess space.

[0046] Continue to see Figure 3 , the second side 22 is The structure comprises a connecting portion 221 parallel to the third side 23 or the fourth side 24 and a horizontal portion 222 parallel to the first side 21. The connecting portion 221 is formed by the base plate 20 extending in a direction away from the first side 22 and is perpendicular to the first side 22. The horizontal portion 222 is located at the other end of the connecting portion 221. The horizontal portion 222 is perpendicular to the connecting portion 221 and parallel to the first side 22.

[0047] Meanwhile, the length of the horizontal portion 222 is less than the length of the first side edge 21 and greater than the width of the connecting portion 221. The second buffer member 40 is sleeved on the horizontal portion 222. Figure 8 As shown, the second buffer member 40 is a hollow rectangular parallelepiped structure, which can block the second side 22 from transmitting noise to the ground.

[0048] In this embodiment, the first buffer member 30 and the second buffer member 40 are made of natural rubber or synthetic rubber, which can balance the weight inside the product and ensure the stability of the product. They can buffer the bottom of the product, reduce noise and vibration, and avoid resonance when the device is working, thereby improving the reliability and stability of the product and extending its service life.

[0049] The first buffer member 30 and the second buffer member 40 can also play a waterproof role.

[0050] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0051] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
