[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] The utility model proposes a denture processing table which is convenient for cleaning debris, comprising a workbench 1 and a protective member 2. The protective member 2 is arranged obliquely on the workbench 1. The cavity formed between the workbench 1 and the protective member 2 is a working area 3. An axial flow fan 4 is arranged under the workbench 1. The air inlet end of the axial flow fan 4 is connected to an air collecting hood 6 through an air inlet pipe 5. The air outlet end of the axial flow fan 4 is connected to an air box 8 through an air outlet pipe 7. The air collecting hood 6 passes through the workbench 1 and is connected to the working area 3. A gas channel 201 is provided on the protective member 2, and the air box 8 is connected to the gas channel 201 of the protective member 2.

[0025] See also Figure 1 and Figure 5 The protective member 2 is fixedly connected to the workbench 1. Its width is no greater than that of the workbench 1. The protective member 2 includes a fixed frame 202, a transparent plate 203, and a gas channel 201. The fixed frame 202 is a rectangular frame, and the transparent plate 203 is fixedly connected within the fixed frame 202. The gas channel 201 is provided on the edge of the fixed frame 202 facing the workbench 1. Two parallel air outlet slots 204 are provided on the side of the gas channel 201 facing the workbench 1. A connecting port 205 is provided at the bottom of the gas channel 201. The gas channel 201 is an N-shaped tube. The fixed frame 202 is made of metal, such as aluminum or stainless steel, and the transparent plate 203 is a glass plate. These plates isolate debris during denture processing without affecting the worker's field of vision.

[0026] See also Figure 2The workbench 1 is C-shaped and includes an upper plate 101, a lower plate 102, and a vertical plate 103 connecting the upper and lower plates 101, 102. The lower plate 102 has legs 105 on its lower surface. The upper and lower plates 101, 102 have the same width, but the upper plate 101 is shorter than the lower plate 102. A rectangular opening 106 is provided through the vertical plate 103. A groove 104 is provided at the contact point between the upper surface of the lower plate 102 and the vertical plate 103. The groove 104 is a triangular groove in cross section and is used to divert sewage. The upper end of the fixed frame 202 is fixedly connected to the free end of the upper plate 101, and the lower end is fixedly connected to the free end of the lower plate 102.

[0027] See also Figure 4 The axial direction of the axial flow fan 4 is consistent with the length direction of the workbench 1. The axial flow fan 4 is a prior art and will not be described in detail here. One end of the air inlet pipe 5 is connected to the axial flow fan 4, and the other end is connected to the air collecting hood 6. The air collecting hood 6 connects the air inlet pipe 5 and the vertical plate 103. The cover body of the air collecting hood 6 is fixedly connected to the rectangular opening 106. The air collecting hood 6 is a horizontally arranged prism shape. The left side of the air collecting hood 6 is closed and the air inlet pipe 5 passes through the left side of the air collecting hood 6. The right side of the air collecting hood 6 is consistent in shape and size with the rectangular opening 106. Start the axial flow fan 4, and under the action of suction, the gas in the working area 3 is sucked into the gas collecting hood 6 and enters the air inlet pipe 5; one end of the air outlet pipe 7 is connected to the axial flow fan 4, and the other end is connected to the bellows 8. The bellows 8 is arranged at the free end of the lower plate 102 of the workbench 1 and is fixedly connected to the lower plate 102. A hole corresponding to the connecting port 205 is provided on the top of the bellows 8, and the connecting port 205 is connected to the bellows 8 through the hole. The axial flow fan 4 sends the gas into the bellows 8 through the air outlet, and then blows it into the working area 3 from the air outlet slit through the gas channel 201, forming two air curtains to prevent denture debris from floating out of the working area 3 and polluting the external environment.

[0028] See also Figure 4 A filter screen 9 is provided at the rectangular opening 106 , and the filter screen 9 is located in the gas collecting cover 6 . The center of the filter screen 9 is recessed toward the gas collecting cover 6 to increase the gas permeability. The filter screen 9 is used to intercept denture debris.

[0029] Half of the area of ​​the vertical plate 103 is less than the area of ​​the rectangular opening 106 and is less than the projection area of ​​the transparent plate 203 on the vertical plate 103 . The rectangular opening 106 almost covers the working area 3 and can inhale the gas in the entire working area 3 to facilitate cleaning of denture debris in the working area 3 .

[0030] See also Figure 3 A water tank 10 is provided on the back of the workbench 1, and the top of the water tank 10 is connected to a water pipe 11. The end of the water pipe 11 passes through the workbench 1 and is close to the filter screen 9. A nozzle 12 is provided at the end of the water pipe 11. A water pump (not shown) is provided in the water tank 10, which can pump water into the water pipe 11 and spray it out from the nozzle 12 to clean the filter screen 9. The sewage flows into the groove 104 under the action of gravity and is discharged from the workbench 1.

[0031] Working process: Start the axial flow fan 4, and the gas in the working area 3 is sucked into the air collecting hood 6, passes through the air inlet pipe, passes through the axial flow fan 4, enters the bellows 8 from the air outlet pipe, and then enters the gas channel 201 through the connecting port 205. It is blown out from the air outlet slit to form an air curtain. The air curtain separates the gas in the working area 3 from the gas in the external environment. The axial flow fan 4 continues to work, so that the gas in the working area 3 forms a cycle through the axial flow fan 4, reducing gas exchange with the external environment and reducing interference with the external environment. When the gas in the working area 3 carries denture debris through the filter 9, the denture debris is larger than the through-holes of the filter 9 and cannot pass through, and stays on the filter 9. When there are too many denture debris on the filter 9, start the water tank 10, flush the filter 9 with water, remove the denture debris, and the denture debris flows into the groove 104 along with the sewage and flows out of the workbench 1.
