Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, and in particular to a dental prosthesis processing grinding and dust collection device. Background Technology

[0002] Currently, the grinding, polishing, and fine cutting of dentures are often performed in open environments, generating significant dust pollution that seriously affects the physical and mental health of dental technicians and students. To alleviate this problem, some denture manufacturing companies and schools have installed large-scale vacuum cleaning equipment in their workshops, which has reduced dust pollution to some extent. However, large-scale vacuum cleaning equipment is expensive, bulky, and difficult to move. While it removes dust already dispersed in the air, technicians are still exposed to dust during operation. Furthermore, the grinding, polishing, and cutting equipment is separate from the vacuum cleaning equipment, preventing simultaneous operation and requiring a large workspace, making operation time-consuming and labor-intensive.

[0003] To address this, existing technologies have developed integrated grinding and dust removal devices, such as the dental grinding dust collection device disclosed in CN117381613A. This device not only grinds dentures but also simultaneously collects and stores the dust generated during the grinding process. However, this solution uses a box to store the dust, which is connected to the suction pipe via a pipeline and fixed to the main body of the device. Cleaning the dust stored inside the box is challenging and the operation is not very convenient. Utility Model Content

[0004] In view of this, the present invention proposes a dust collection device for denture processing and polishing. The device uses a fixed cylinder connected to a filter element to connect to an air duct, thereby filtering the air entering the air duct and blocking dust. The dust will accumulate in the dust collection box under the action of gravity. The dust collection box is sealed to the fixed cylinder by the first and second sealing elements, preventing the dust from escaping. In addition, the dust can be cleaned directly by removing the inserted dust collection box. The first and second sealing elements do not obstruct the installation and removal of the dust collection box, making the cleaning operation more convenient.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0033] like Figure 1-5 As shown, the dental prosthesis processing and polishing dust collection device of this utility model includes a housing 1, a fixed cylinder 2, a filter element 3, a dust collection pipe 4, and a dust collection box 5.

[0034] The casing 1 is equipped with an air duct 101. The casing 1 is formed by metal plates and has a square-shaped exterior. Inside the casing 1, there are a dust removal chamber, a fan chamber, and an electrical chamber. The air duct 101 is located in the electrical chamber and connects the dust removal chamber and the fan chamber.

[0035] The fixed cylinder 2 is installed on the housing 1, specifically inside the dust removal chamber of the housing 1. The air duct 101 is installed on the top of the fixed cylinder 2. That is to say, the electrical chamber is located on top of the dust removal chamber and the fan chamber, but the dust removal chamber and the fan chamber are not directly connected. The fixed cylinder 2 is open on both the top and bottom sides, and the top is fixed to the housing 1. At the top axis of the fixed cylinder 2, the housing 1 has an air inlet for the air duct 101. A first sealing element 21 is installed on the bottom opening side edge of the fixed cylinder 2.

[0036] The filter element 3 is installed inside the fixed cylinder 2 and connected to the ventilation duct 101 to filter impurities flowing into the duct 101. The filter element 3 is cylindrical in shape and hollow inside with an opening at the top. The top of the filter element 3 is attached and fixed to the housing 1. Its side is the filtration part and the bottom is a sealed structure. The top opening of the filter element 3 is connected to the air inlet of the duct 101, so that if the gas inside the fixed cylinder 2 enters the duct 101, it will be filtered out by the filter element 3 to remove dust and impurities. Since the filtration part of the filter element 3 is made of porous material, its rigidity is poor. In order to avoid deformation during the disassembly and assembly process, fixing rings and bottom plates are respectively set on the upper and lower sides of the filter element 3 to ensure that it has good mechanical stability.

[0037] The dust collection pipe 4 is installed on the housing 1, and one end extends into the fixed cylinder 2. Specifically, the other end of the dust collection pipe 4 passes through the fan compartment and extends to the outside of the housing 1. It extends to the workbench through a plastic corrugated pipe or the like for dust collection. The end that extends into the fixed cylinder 2 sends the air drawn in from the outside into the fixed cylinder 2 and filters the dust through the filter element 3.

[0038] The dust collection box 5 is inserted into the housing 1. The top of the dust collection box 5 is open and connected to the fixed cylinder 2. The dust collection box 5 is provided with a second sealing element 51. The second sealing element 51 is located between the dust collection box 5 and the fixed cylinder 2 and seals the gap between the dust collection box 5 and the fixed cylinder 2 by deformation. The dust collection box 5 is also cylindrical and its diameter is small compared with that of the fixed cylinder 2, so as to avoid the gap due to the diameter difference when the first sealing element 21 and the second sealing element 51 are connected, which would affect the sealing effect.

[0039] In this embodiment, the fixed cylinder is connected to the filter element in the air duct, thereby filtering the air entering the air duct and blocking dust. The dust will accumulate in the dust collection box under the action of gravity. The dust collection box is sealed with the fixed cylinder by the first and second sealing elements, so that the dust will not escape. In addition, the dust can be cleaned directly by removing the inserted dust collection box. The first and second sealing elements do not hinder the installation and removal of the dust collection box, making the cleaning operation more convenient.

[0040] In some embodiments, the dust collection box 5 is further provided with a bending portion 52, which bends outward along the opening side edge of the dust collection box 5, and the second sealing member 51 is fixed on the bending portion 52. The bending portion 52 forms a handle on one side of the dust collection box 5.

[0041] The bending part 52 can be directly bent into shape as a whole during the production of the dust collection box 5. Specifically, the bending part 52 is wrapped around the top of the dust collection box 5, and one side protrudes and bends downward to form a handle for the user to push and pull, so as to facilitate insertion or pulling out of the housing 1. At the same time, the bending part 52 can increase the mechanical strength of the opening side of the dust collection box 5 and prevent it from deforming during use, thus affecting the sealing effect.

[0042] In addition, an annular surface is formed on the bent portion 52, and the second sealing element 51 is disposed on the annular surface, which can be fixed by means of adhesive or the like.

[0043] In one embodiment, the housing 1 is provided with a cleaning position, and the housing 1 is provided with a slot 102 located on the cleaning position. The bent part 52 of the dust collection box 5 is installed on the cleaning position through the slot 102, and the dust collection box 5 is connected and sealed with the fixed cylinder 2.

[0044] The slot 102 is on the housing 1. The width is greatest at the insertion position of the dust collection box 5 and smallest at the insertion position of the dust collection box 5. At the position with the smallest width, the slot 102 will squeeze the dust collection box 5 tightly against the fixing cylinder 2, causing the second sealing ring 51 to deform, thereby sealing the gap. Specifically, during the insertion of the dust collection box 5, as the distance between the dust collection box 5 and the fixing cylinder 2 gradually decreases, the second sealing ring 51 will also be gradually squeezed. Conversely, when the dust collection box 5 is removed, the second sealing ring 51 gradually restores its deformation.

[0045] In some embodiments, the first sealing member 21 has a U-shaped cross-section in the radial direction, and the second sealing member 51 has an O-shaped cross-section in the radial direction. The U-shaped design of the first sealing member 21 can perfectly wrap around the bottom edge of the fixed cylinder 2 and will not fall off as the dust collection box 5 moves, thus having high mechanical stability. At the same time, this design will not cause it to have large deformation, making the first sealing member 21 less prone to damage. The O-shaped design of the cross-section of the second sealing member 51, on the other hand, gives it a large deformation space, so that it can be gradually compressed during the insertion of the dust collection box 5. After compression, the contact area with the first sealing member 21 will increase, thus significantly improving the sealing effect.

[0046] In some embodiments, a fixing bracket 6 is also provided. The fixing bracket 6 is disposed inside the fixing cylinder 2 and passes through the filter element 3 to fix the filter element 3 to the fixing cylinder 2. The fixing bracket 6 fixes the filter element 3 and maintains its good stability, preventing gaps between it and the housing 1 from affecting the dust removal effect. At the same time, the fixing bracket 6 can also be used to disassemble the filter element 3 for replacement and maintenance.

[0047] In a specific embodiment, the fixing bracket 6 includes a base 61, a screw 62, a washer 63, and a locking nut 64. The base 61 is fixed on the housing 1 and located inside the fixing cylinder 2. The bottom of the base 61 has a threaded groove. One end of the screw 62 is inserted into the threaded groove and threadedly connected to the base 61, and the other end passes through the filter element 3 and extends to the bottom of the filter element 3. The washer 63 is sleeved on the outside of the screw 62 and abuts against the bottom of the filter element 3. The locking nut 64 is threadedly connected to the bottom end of the screw 62 and squeezes the washer 63 to fix the filter element 3.

[0048] This design allows for the disassembly of filter element 3, which is secured by threads, resulting in better stability during use. Furthermore, since a single screw 62 cannot impede the rotation of filter element 3, a double screw 62 fixing structure is used in the fixing bracket 6 to further improve the installation stability of filter element 3.

[0049] In some embodiments, one end of the dust collection pipe 4 is located inside the fixed cylinder 2 and is positioned outside the bottom end of the filter element 3, and is eccentrically positioned on the fixed cylinder 2. This arrangement can reduce the space occupied by the dust collection pipe 4 in the fan compartment, and at the same time prevent the incoming air from directly blowing on a part of the filter element 3. A baffle is provided at the end of the dust collection pipe 4, and an air outlet is provided on its side. This arrangement can prevent large particles of slag from impacting the filter element 3 and the fixed cylinder when they enter. After most of the impact is removed by the baffle, the large particles of slag can fall into the dust collection box 5 under the action of gravity.

[0050] In addition, in this embodiment, a fan 7 and a polishing pen 8 are also provided. The fan 7 is fixed on the housing 1 and the suction end is connected to the ventilation duct 101. Specifically, the fan 7 is set in the fan compartment, and the polishing pen 8 is connected to the electrical compartment through a wire harness. A bracket is provided on the top of the housing 1. The polishing pen 8 is adapted to the bracket and can be placed on the bracket when not in use.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
