[0001] This utility model relates to the field of dental implant technology, specifically an oil mist collection cover. Background Technology

[0002] During the fabrication of dental implant crowns, high-speed rotating instruments generate a large amount of oil mist, water mist, and fine particles. If these contaminants are not collected and treated promptly, they can pollute the environment and pose a threat to the health of patients and dentists. However, existing oil mist collectors often experience oil mist and fine particles accumulating inside the device after prolonged use. These contaminants are not only difficult to clean but also affect the collector's performance and efficiency. Therefore, innovating and improving oil mist collectors to more effectively collect and clean these contaminants is crucial for enhancing the safety and efficiency of dental implant crown fabrication. To this end, we propose an oil mist collection hood. Utility Model Content

[0025] 1. By setting the first filter component, the motor is started, and the motor drives the rotating shaft to rotate, which in turn drives multiple paddles to rotate. At the same time, the fan starts synchronously. Through the rotation of the fan and paddles, oil mist and dust particles in the hood are sucked in. The oil mist and dust enter the first tube. The rotation of the rotating shaft driven by the motor will synchronously drive the rotating wheel to rotate, which in turn drives the rotating rod to rotate. The rotating rod drives the connecting rod to perform linear reciprocating motion under the limit of the limiting plate, which in turn drives the folding sleeve to fold repeatedly. Through repeated folding, the oil mist and dust adhering to the inner wall of the first tube and inside and outside the folding sleeve can be shaken off.

[0026] 2. By setting a second filter component, which works in conjunction with the first filter component, the first filter component performs preliminary filtration. Then, the remaining oil mist and dust enter the second pipe through the first pipe. After being filtered again by three filter plates, they are exhausted by a fan. The secondary filtration ensures that the gas discharged from the device meets safety standards. Attached Figure Description

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] like Figure 1-4 As shown, in this embodiment, an oil mist collection hood includes: a hood body 1, a first tube body 2, a first filter assembly 3, a second tube body 4, and a second filter assembly 5. The bottom of the hood body 1 is open, and a fixing ring 11 is fixedly connected to the bottom of the hood body 1. The first tube body 2 is fixedly connected inside the hood body 1. The second tube body 4 is fixedly connected to the outer end of the first tube body 2. The first tube body 2 and the second tube body 4 are detachable and replaceable.

[0035] The first filter assembly 3 includes: a motor 31, a support plate 32, paddles 33, a rotating wheel 34, a limiting plate 35, a folding sleeve 36, and a U-shaped support 37. The motor 31 is fixedly connected to the outside of the first tube body 2, and the drive end of the motor 31 extends into the first tube body 2 and is fixedly connected to a rotating shaft 311. Both support plates 32 are fixedly connected inside the first tube body 2, and the rotating shaft 311 is rotatably sleeved inside the two support plates 32. Multiple paddles 33 are fixedly connected to the outside of the rotating shaft 311. The rotating wheel 34 is fixedly connected to one end of the rotating shaft 311, and the outer side of the rotating wheel 34 is rotatably connected to... There is a rotating rod 341, one end of which is rotatably connected to a connecting rod 342; a limiting plate 35 is fixedly connected inside the first tube body 2, and the connecting rod 342 is limited and slidably within the limiting plate 35; a folding sleeve 36 is disposed inside the first tube body 2, one end of which is fixedly connected to the inner wall of the first tube body 2; a loop support 37 is fixedly connected to the other end of the folding sleeve 36, and one end of the connecting rod 342 is fixedly connected to the loop support 37; it should be noted that the turbulence generated by the simultaneous rotation of the fan 51 and multiple paddles 33 will not affect the suction of oil mist and dust.

[0036] In this embodiment, a connecting frame 38 is fixedly connected to the outside of the connecting rod 342. One end of the connecting frame 38 is fixedly connected to the loop support 37. The loop support 37 can support the folding sleeve 36 and also serve as a connection. By setting the connecting frame 38, the repeated folding of the folding sleeve 36 can be made more stable.

[0037] The folding sleeve 36 has multiple layers of filter screens 39 fixedly connected inside. As the folding sleeve 36 is repeatedly folded, preliminary filtration can be performed because of the multiple layers of filter screens 39 fixedly connected inside.

[0038] In practice, the motor 31 is started, which drives the rotating shaft 311 to rotate, thereby driving multiple paddles 33 to rotate. At the same time, the fan 51 is started synchronously. Through the rotation of the fan 51 and the paddles 33, oil mist and dust particles in the hood 1 are sucked out. The oil mist and dust enter the first tube 2. The rotating shaft 31 driven by the motor 31 will synchronously drive the rotating wheel 34 to rotate, thereby driving the rotating rod 341 to rotate. The rotating rod 341 drives the connecting rod 342 to perform linear reciprocating motion under the limit of the limiting plate 35, thereby driving the folding sleeve 36 to fold repeatedly. Through repeated folding, the oil mist and dust adhering to the inner wall of the first tube 2 and inside and outside the folding sleeve 36 can be shaken off.

[0039] Furthermore, a base plate 6 is detachably connected to the bottom of the first tube 2. By removing the base plate 6, the accumulated oil mist residue and dust can be cleaned out of the first tube 2.

[0040] Example 2

[0041] Based on Embodiment 1, a second filter assembly 5 is provided to perform secondary filtration so that the gas discharged from the device meets safety standards.

[0042] like Figure 1 As shown, in this embodiment, the second filter assembly 5 includes: a fan 51 and filter plates 52. The fan 51 is fixedly connected to the top of the second pipe body 4; the three filter plates 52 are all slidably connected inside the second pipe body 4, and the three filter plates 52 can be slidably removed from the second pipe body 4 for easy replacement.

[0043] In practice, the first filter assembly 3 performs preliminary filtration, and then the remaining oil mist and dust enter the second pipe 4 through the first pipe 2. After being filtered again by the three filter plates 52, they are then drawn out by the fan 51.

[0044] Working principle: First, the device is fitted onto the dental implant crown manufacturing equipment. The cover 1 is then fixedly connected to the equipment via a fixing ring 11. The manufacturing equipment then performs milling or drilling operations on the implant within the cover 1. The motor 31 is started, driving the rotating shaft 311 to rotate, which in turn drives multiple paddles 33 to rotate. Simultaneously, the blower 51 starts. The rotation of the blower 51 and the paddles 33 draws in oil mist and dust particles from the cover 1. The oil mist and dust enter the first tube 2. The rotation of the rotating shaft 311, driven by the motor 31, synchronously drives the rotating wheel 34 to rotate, which in turn drives the rotating rod 341 to rotate. The moving rod 341 drives the connecting rod 342 to perform linear reciprocating motion under the limit of the limiting plate 35, which in turn drives the folding sleeve 36 to fold repeatedly. After repeated folding, the oil mist and dust adhering to the inner wall of the first tube 2 and inside and outside the folding sleeve 36 can be shaken off. The bottom plate 6 can be removed to clean the accumulated oil mist residue and dust out of the first tube 2. While the folding sleeve 36 is folding repeatedly, it can perform preliminary filtration because it is fixedly connected with multiple layers of filter screens 39. Then the remaining oil mist and dust enter the second tube 4 through the first tube 2. After being filtered again by the three filter plates 52, they are sucked out by the fan 51.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
