After the device is started, the first motor 103 will be started. After the first motor 103 is started, the threaded rod 104 will rotate. When the threaded rod 104 rotates, the slider 105 will move along the threaded rod 104. When the slider 105 moves, it will drive the second motor 106 to move together. After the second motor 106 is started, the rotating shaft 107 will rotate. When the rotating shaft 107 rotates, it will drive the electric push rod 108 to rotate together. After the electric push rod 108 is started, the sliding rod 109 will move and drive the carving tool 110 to approach the denture blank together. Because the electric push rod 108 is in a rotating state, the carving tool 110 will also rotate together. When the carving tool 110 contacts the denture blank, it will carve it. At the same time, after the water pump 114 is started, the water in the water storage tank 115 will enter the inside of the water pipe 112 through the pipeline. The water flow will spray out through the first round holes 113 and flow towards the denture blank, so that the debris generated when the carving tool 110 carves the denture blank will be washed in time. When the water flow flows, it will contact the baffle 118. Because the baffle 118 is an arc-shaped structure, the water flow will flow along the surface of the baffle 118 and flow out from the edge of the baffle 118 after reaching the surface of the baffle 118, so that the water flow will continue to flow towards the surface of the denture blank, increasing the water flow rate reaching the surface of the denture blank; by setting the baffle 118, the baffle 118 will guide the water flow when the water flow direction deviates, increasing the water flow rate reaching the surface of the denture blank, enhancing the cleaning effect of the device on the denture blank, and reducing the debris on the surface of the denture blank.

[0027] Please refer to Figure 3 and Figure 4 As shown, a fixing groove 2 is provided in the middle of the baffle 118; a second connecting rod 22 is hinged in the middle of the fixing groove 2; a counterweight 23 is fixedly connected to the end of the second connecting rod 22; the other end of the second connecting rod 22 communicates with a water inlet hopper 24; a iron ball 25 is fixedly connected to the middle of the second connecting rod 22; due to the self-weight of the counterweight 23, the second connecting rod 22 will be inclined and contact the baffle 118 under normal conditions. Water will splash during the flowing process and reach the surface of the water inlet hopper 24. Subsequently, these water droplets will enter the inside of the second connecting rod 22 through the water inlet hopper 24. When the water in the second connecting rod 22 reaches a certain volume, the second connecting rod 22 will be inclined in the reverse direction, causing the water to flow out from the water inlet hopper 24. Then, the second connecting rod 22 will reset under the gravity of the counterweight 23 again. When the second connecting rod 22 resets, it will drive the iron ball 25 to move together. When the iron ball 25 moves, it will contact the surface of the baffle 118 and strike the surface of the baffle 118, causing the surface of the baffle 118 to vibrate; the second connecting rod 22 will rotate reciprocally as the volume of the internal water changes, and when the iron ball 25 moves, it will strike the baffle 118, accelerating the falling speed of the water droplets on the surface of the baffle 118, reducing the remaining water droplets on the surface of the baffle 118, improving the cleanliness of the surface of the baffle 118, and at the same time increasing the water flow rate reaching the surface of the denture blank, improving the utilization rate of water resources by the device.

Since the rubber pad 3 is a flexible material, the rubber pad 3 will absorb the impact generated when the iron ball 25 contacts the baffle 118, reducing the impact on the baffle 118; by setting the rubber pad 3, the rubber pad 3 will absorb the impact force received when the baffle 118 contacts the iron ball 25, playing a protective role for the baffle 118 and reducing the scratches left on the surface of the baffle 118 due to collision.

[0029] Please refer to Figure 3As shown, a fixing ring 4 is fixedly connected to the inside of the adjacent drawstrings 117; a plurality of bristles 42 are fixedly connected to the inner side wall of the fixing ring 4; when the sliding rod 109 moves, it will drive the first connecting rod 111 and the water pipe 112 to approach the denture blank together, and the water pipe 112 will drive the drawstring 117 to move together. The drawstring 117 will drive the fixing ring 4 to move together, and the fixing ring 4 will drive the bristles 42 to move together. When the bristles 42 move, they will come into contact with the denture blank. Since the water pipe 112 is in a rotating state, the bristles 42 are also in a rotating state. When the bristles 42 come into contact with the denture blank, they will clean its surface, reducing the impurities on the surface of the denture blank; through the cooperative action of the fixing ring 4 and the bristles 42, when the fixing ring 4 moves, it will drive the bristles 42 to approach the denture blank together and make the bristles 42 clean the surface of the denture blank, realizing the cleaning of the surface of the denture blank by the device, reducing the impurities attached to the surface of the denture blank, and improving the smoothness of the surface of the denture blank.

[0030] Please refer to Figure 1 and Figure 5 As shown, a plurality of second round holes 5 are formed in the top of the support base 1; a collection box 52 is fixedly connected to the bottom of the support base 1; the water pump 114 and the collection box 52 are connected through a pipeline; a fixing seat 53 is fixedly connected to the inner side wall of the second round hole 5; a screw conveyor 54 is rotatably connected to the bottom of the fixing seat 53; the wastewater after cleaning the denture blank will flow on the surface of the support base 1 and flow into the inside of the second round hole 5. When the wastewater flows in the second round hole 5, it will come into contact with the screw conveyor 54. The screw conveyor 54 will rotate under the action of the water flow, so that the debris contained in the water flow will flow along the second round hole 5 together with the water flow. Subsequently, the wastewater will reach the inside of the collection box 52, and after the water pump 114 is started, it will pump the water in the collection box 52 and send the wastewater to the inside of the water storage tank 115 through the pipeline, realizing the recycling of water resources by the device.

[0031] Please refer to Figure 5 As shown, a plurality of third connecting rods 6 are fixedly connected to the middle of the screw conveyor 54; a scraping plate 62 is fixedly connected to the end of the third connecting rod 6; when the screw conveyor 54 rotates, it will drive the third connecting rod 6 to rotate together. When the third connecting rod 6 rotates, it will drive the scraping plate 62 to rotate together. When the scraping plate 62 moves, it will come into contact with the inner wall of the second round hole 5 and clean it, reducing the impurities attached to the inner wall of the second round hole 5 and improving the smoothness of the water flow through the second round hole 5.

[0032] Please refer to Figure 5 As shown, a filter pad 7 is fixedly connected to the middle of the collection box 52; the filter pad 7 is located at the bottom of the support base 1; when the wastewater enters the inside of the collection box 52, it will come into contact with the filter pad 7, and the filter pad 7 will filter the debris contained in the wastewater, reducing the debris contained in the collection box 52.

[0033] Working principle: Place the denture blank on the fixing mechanism 116 and fix it, then start the device. After the device starts, the first motor 103 will be started. After the first motor 103 starts, the threaded rod 104 will rotate. When the threaded rod 104 rotates, the slider 105 will move along the threaded rod 104. When the slider 105 moves, it will drive the second motor 106 to move together. After the second motor 106 starts, the rotating shaft 107 will rotate. When the rotating shaft 107 rotates, it will drive the electric push rod 108 to rotate together. After the electric push rod 108 starts, the sliding rod 109 will move and drive the carving tool 110 to approach the denture blank together. Because the electric push rod 108 is in a rotating state, the carving tool 110 will also rotate together. When the carving tool 110 contacts the denture blank, it will carve the denture blank. At the same time, after the water pump 114 starts, the water in the water storage tank 115 will enter the inside of the water pipe 112 through the pipeline. The water flow will spray out through the first round hole 113 and flow towards the denture blank, so that the debris generated when the carving tool 110 carves the denture blank will be washed in time. When the water flow is flowing, it will contact the baffle 118. Because the baffle 118 is an arc-shaped structure, after the water flow reaches the surface of the baffle 118, it will flow along the surface of the baffle 118 and flow out from the edge of the baffle 118, so that the water flow will continue to flow towards the surface of the denture blank, increasing the water flow reaching the surface of the denture blank; because of the self-weight of the counterweight 23, the second connecting rod 22 will be inclined normally and contact the baffle 118. When the water flow is flowing, it will splash and reach the surface of the water inlet hopper 24. Then these water droplets will enter the inside of the second connecting rod 22 through the water inlet hopper 24. When the water in the second connecting rod 22 reaches a certain volume, the second connecting rod 22 will be inclined in the reverse direction so that the water flow flows out from the water inlet hopper 24. Then the second connecting rod 22 will reset under the gravity of the counterweight 23 again. When the second connecting rod 22 resets, it will drive the iron ball 25 to move together. When the iron ball 25 moves, it will contact the surface of the baffle 118 and knock on the surface of the baffle 118, making the surface of the baffle 118 vibrate; when the iron ball 25 knocks on the surface of the baffle 118, the rubber pad 3 will contact the baffle 118 earlier than the iron ball 25. Because the rubber pad 3 is a flexible material, the rubber pad 3 will absorb the impact generated when the iron ball 25 contacts the baffle 118, reducing the impact force on the baffle 118; when the sliding rod 109 moves, it will drive the first connecting rod 111 and the water pipe 112 to approach the denture blank together. The water pipe 112 will drive the pull rope 117 to move together. The pull rope 117 will drive the fixing ring 4 to move together. The fixing ring 4 will drive the brush bristles 42 to move together. When the brush bristles 42 move, they will contact the denture blank. Because the water pipe 112 is in a rotating state, the brush bristles 42 are also in a rotating state. When the brush bristles 42 contact the denture blank, they will clean the surface of the denture blank, reducing the impurities on the surface of the denture blank;The wastewater after cleaning the denture blank will flow on the surface of the support base 1 and flow into the interior of the second round hole 5. When the wastewater flows in the second round hole 5, it will come into contact with the auger 54. The auger 54 will rotate under the action of the water flow, so that the debris contained in the water flow will flow along the second round hole 5 together with the water flow. Subsequently, the wastewater will reach the interior of the collection box 52. After the water pump 114 is started, it will pump the water in the collection box 52 and send the wastewater to the interior of the water storage tank 115 through a pipeline, realizing the recycling of water resources by the device; when the auger 54 rotates, it will drive the third connecting rod 6 to rotate together. When the third connecting rod 6 rotates, it will drive the scraper 62 to rotate together. When the scraper 62 moves, it will come into contact with the inner wall of the second round hole 5 and clean it, reducing the impurities attached to the inner wall of the second round hole 5 and improving the smoothness of the water flow passing through the second round hole 5; when the wastewater enters the interior of the collection box 52, it will come into contact with the filter pad 7. The filter pad 7 will filter the debris contained in the wastewater, reducing the debris contained in the collection box 52.
