[0023] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.
[0024] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0025] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.
[0026] An embodiment of this utility model provides a range hood motor with an oil-blocking ring, such as... Figure 1-4 Shown, including:
[0027] The motor body 100 includes a housing 110, and a fixing structure 120 is provided on the outer wall of the housing 110.
[0028] The oil baffle ring 200 includes a connecting part 210 that is detachably connected to the fixed structure 120 and an oil baffle ring 220. The oil baffle ring 220 is sleeved on the outside of the housing 110 and the inner wall of the oil baffle ring 220 abuts against the outer wall of the housing 110.
[0029] Fastener 300 passes through fixing structure 120 and connecting part 210, and fixes motor body and oil baffle ring 200 to range hood.
[0030] The motor housing 110 is a protective structure for the motor, typically made of materials such as metal or plastic, to protect the internal motor components. A fixing structure 120 is provided on the outer wall of the housing 110 of the motor body 100. This structure is used to fix the oil baffle ring 200 to the motor body 100. The fixing structure 120 can be a protrusion, a groove, or other form of mechanical structure, designed to ensure that the oil baffle ring 200 can be stably installed on the motor body 100. The oil baffle ring 200 includes a connecting portion 210 and an oil baffle ring 220. The connecting portion 210 is the part that connects the oil baffle ring 200 to the fixing structure 120 of the motor body 100. It is designed to be detachably connected to the fixing structure 120, facilitating the installation and replacement of the oil baffle ring 200. The inner wall of the oil baffle ring 220 can abut against the outer wall of the housing 110 of the motor body 100. This design effectively prevents grease from flowing along the motor housing 110 into the interior of the range hood. Fastener 300 is a component used to secure the motor body and the oil-retaining ring 200 to the range hood. It can be a screw, bolt, clip, or other form of fastening element. Fastener 300 passes through the fixing structure 120 and the connecting portion 210, ensuring that the oil-retaining ring 200 is securely fixed to the motor body 100. The design of the oil-retaining ring 200 prevents grease from entering the range hood during operation, thereby extending the range hood's lifespan and reducing maintenance costs. The oil-retaining ring 200 is simple yet practical, effectively protecting the motor from grease corrosion.
[0031] In some embodiments, the fixing structure 120 is provided with a mounting hole 130, and the connecting part 210 can enter the mounting hole 130 and connect with the fixing structure 120.
[0032] The mounting hole 130 on the fixing structure 120 is used to fix the connecting part 210, allowing the connecting part 210 to be inserted and connected thereto. This design ensures that the connection between the oil baffle ring 200 and the motor body 100 is both firm and stable. The connecting part 210 of the oil baffle ring 200 is designed to fit and enter the mounting hole 130. This design allows the connecting part 210 to be easily inserted into the mounting hole 130 and connected to the fixing structure 120. After the connecting part 210 is connected to the fixing structure 120 through the mounting hole 130, fasteners 300 (such as screws, bolts, nuts, etc.) can pass through the connecting part 210 and the fixing structure 120 to further fix the motor body and the oil baffle ring 200 to the range hood. The cooperation between the mounting hole 130 and the connecting part 210 improves the connection stability between the oil baffle ring 200 and the motor body 100. This design makes the installation and removal of the oil baffle ring 200 more convenient, facilitating maintenance and cleaning.
[0033] Furthermore, an opening 140 is provided on the side wall of the mounting hole 130. The width of the opening 140 is smaller than the diameter of the mounting hole 130, and the connecting part 210 can pass through the opening 140 and be inserted into the mounting hole 130.
[0034] An opening 140 is provided on the side wall of the mounting hole 130. This opening 140 is an opening or notch, and its width is smaller than the diameter of the mounting hole 130. This dimensional relationship allows the connecting part 210 to pass through the opening 140 when inserted into the mounting hole 130, but after insertion, the width of the connecting part 210 exceeds the width of the opening 140, thus being locked into the mounting hole 130, forming a self-locking mechanism. The connecting part 210 is designed to pass through the opening 140. If the connecting part 210 is elastic, it can pass through the opening 140 by compression, but after passing through the opening 140, the width of the connecting part 210 will exceed the width of the opening 140, allowing the connecting part 210 to be locked into the mounting hole 130. This design provides a simple and effective fixing method. The cooperation between the opening 140 and the connecting part 210 forms a self-locking mechanism, making the connecting part 210 more stable in the mounting hole 130 and reducing the risk of loosening due to vibration or gravity.
[0035] Furthermore, the connecting part 210 includes a limiting pad 230. The upper end of the fixing structure 120 is provided with a limiting groove 150 that communicates with the mounting hole 130. The limiting pad 230 is disposed in the limiting groove 150, and the outer diameter of the limiting pad 230 is larger than the diameter of the mounting hole 130.
[0036] The connecting part 210 includes a limiting pad 230, which prevents the connecting part 210 from dislodging from the mounting hole 130, ensuring the correct position of the connecting part 210 within the mounting hole 130. The upper end of the fixing structure 120 is designed with a limiting groove 150. The limiting pad 230 is disposed within the limiting groove 150, and the outer diameter of the limiting pad 230 is larger than the diameter of the mounting hole 130, ensuring that the limiting pad 230 cannot pass through the mounting hole 130. The cooperative use of the limiting pad 230 and the limiting groove 150 improves the connection stability between the connecting part 210 and the fixing structure 120, reducing the risk of loosening due to vibration or gravity.
[0037] Furthermore, the connecting part 210 is provided on the upper end surface of the oil baffle ring 220, and the connecting part 210 is close to the outer periphery of the upper end surface of the oil baffle ring 220.
[0038] The connecting part 210 is provided on the upper end face of the oil baffle ring 220, and the connecting part 210 is close to the outer periphery of the upper end face of the oil baffle ring 220. This means that the connecting part 210 is located at the edge of the oil baffle ring 200. By placing the connecting part 210 on the end face close to the outer wall of the oil baffle ring 220, the connecting part 210 of the oil baffle ring 200 can more easily contact the mounting hole 130 of the fixing structure 120, which facilitates the installation and removal of the oil baffle ring 200.
[0039] Furthermore, the cross-section of the connecting part 210 is T-shaped.
[0040] The cross-section of the connecting part 210 is T-shaped, meaning it has a vertical part (the vertical portion of the T) and a horizontal part (the top horizontal bar of the T). The T-shaped cross-section design provides better structural stability because the horizontal part can distribute the load and reduce the risk of the connecting part 210 deforming under stress.
[0041] In some embodiments, one end face of the oil baffle ring 220 abuts against the fixing structure 120, and the other end face abuts against the range hood.
[0042] One end face of the oil-retaining ring 220 is designed to abut against the fixed structure 120, while the other end face abuts against the range hood. This design allows the oil-retaining ring 220 to form a sealed barrier between the motor body 100 and the range hood. The contact design at both ends of the oil-retaining ring 220 helps to improve sealing, preventing grease and dirt from leaking from both ends, thereby protecting the cleanliness of the motor body 100 and the interior of the range hood.
[0043] In some embodiments, the oil baffle ring 220 is further provided with an extension ring 240, the inner diameter of the extension ring 240 being equal to the inner diameter of the oil baffle ring 220 and the outer diameter of the extension ring 240 being smaller than the outer diameter of the oil baffle ring 220.
[0044] The oil-blocking ring 220 incorporates an extension ring 240, which increases the contact area between the oil-blocking ring 200 and the motor body 100, ensuring effective blocking of grease and dirt. The extension ring 240's design allows the oil-blocking ring 220 to adapt to different sizes of motor bodies 100 and range hoods, improving design flexibility. The smaller outer diameter of the extension ring 240 facilitates installation of the oil-blocking ring 220 within limited space, while minimizing interference with surrounding components.
[0045] Furthermore, the extension ring 240 is disposed on the end face of the oil baffle ring 220 away from the connecting part 210.
[0046] The extension ring 240 is positioned on the end face of the oil-blocking ring 220 away from the connecting portion 210. This means that the extension ring 240 is located at the far end of the oil-blocking ring 220, opposite to the connecting portion 210. When the diameter of the mounting portion of the range hood used to install the motor body 100 is larger than the diameter of the motor body 100, the gap between the motor body 100 and the range hood is larger. The extension ring 240 can be used to fill the gap between the motor body 100 and the range hood, preventing grease and dirt from entering the motor from this end.
[0047] In some embodiments, the fastener 300 includes a head 310, a limiting portion 320, and a fastening portion 330 for cooperating with a range hood, the fastening portion 330 being provided with threads.
[0048] Because the fastening part 330 has threads while the limiting part 320 does not, when the limiting part 320 contacts the threaded hole of the range hood, its smooth, threadless surface prevents it from fitting into the threaded hole, thus effectively limiting the insertion depth. The design of the limiting part 320 prevents the fastener 300 from being over-tightened, avoiding damage to the oil baffle ring 200 or the range hood.
[0049] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
