Description

Technical Field

[0001] The invention relates to the technical field of dental medical treatment, in particular to a water grinder for repairing tooth moulds. Background Art

[0002] In modern stomatology, tooth restoration is a key technology, and the quality of tooth molds has a vital impact on the restoration effect. Whether it is making dentures, crowns, or auxiliary molds required for orthodontic treatment, high-precision processing is required. As people's requirements for oral health and beauty continue to increase, the accuracy and adaptability requirements of dental restorations are becoming increasingly stringent.

[0003] At present, a water grinder is used to repair the tooth mold. After the tooth mold is repaired, debris will fall from the bottom of the repair port. Since the water nozzle is set on the back surface of the grinding wheel, when the grinding wheel rotates at a high speed, the sprayed water contacts the surface of the grinding wheel and will splash with the centrifugal force. However, the groove where the debris accumulates is set on the opposite side of the grinding wheel. Only a small part of the splashed water will be thrown into the groove through the rotation of the grinding wheel. The inside of the groove is a flat chamber with a certain depth. When water enters the chamber, the chamber cannot play a certain flow effect on the incoming water, resulting in the problem of water retention inside the chamber. Summary of the invention

[0004] The object of the present invention is to provide a water grinder for repairing tooth molds to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides a water mill for repairing a tooth mold, comprising a control box, a mold repairing mechanism and a dirt collecting tank; The control box includes a front cover, a die repair port and a collection box. A hinge is rotatably connected to one side of the front cover surface. The front cover is opened and closed on the control box surface through the hinge. The inner bottom of the collection box is correspondingly connected to the die repair port surface. The die repairing mechanism includes a grinding wheel, an inner cavity and a water spray assembly. The grinding wheel rotates inside the die repairing port through a control box. The water spray assembly is fixedly mounted on the surface of the inner cavity, and one side of the water spray assembly extends to the bottom of the back of the grinding wheel. The sewage collecting tank comprises a water guide plate and a drainage plate. The water guide plate is fixedly installed on the top of the inner side of the sewage collecting tank, and the drainage plate is fixedly installed on the bottom of the inner side of the sewage collecting tank.

[0006] As a further improvement of the technical solution, baffle plate 1 and baffle plate 2 are fixedly installed on both sides of the inner cavity surface, and a sewage discharge pipe is arranged on one side of the sewage collecting tank surface.

[0007] As a further improvement of the present technical solution, the water spray assembly includes a docking port, a water pipe is fixedly installed on the lower surface of the docking port, a socket is fixedly sleeved on the lower surface of the water pipe, and a water spray port is opened on one side of the socket surface.

[0008] As a further improvement of the technical solution, a sewage outlet is provided on one side of the lower surface of the front cover, and a filter plate is movably connected to the upper surface of the collection box.

[0009] As a further improvement of the technical solution, one side of the sewage outlet surface is correspondingly connected to the sewage pipe.

[0010] As a further improvement of the technical solution, the docking port passes through the top of the front cover, is connected to an external water pipeline, and introduces water to the water outlet through a water pipe and a socket, and sprays water on the back surface of the grinding wheel.

[0011] As a further improvement of the present technical solution, the grinding wheel rotates, driving the water nozzle to spray water on the back of the grinding wheel. A through hole is opened on the surface of the grinding wheel. Water splashes on the surface of the grinding wheel through the through hole and is thrown to the surface of the inner cavity. The water is guided to the surface of the water guide plate through baffles one and two. The water guide plate is curved and concave downward, guiding the water from the water guide plate to the surface of the drainage plate, and the water flows out from the bottom of the inner side of the sewage collection tank along the drainage plate.

[0012] As a further improvement of the present technical solution, baffle one and baffle two are symmetrically distributed on both sides of the upper surface of the sewage collecting trough, and are connected to the upper surface of the water guide plate. One side of the lower surface of the water guide plate is vertically corresponding to the upper surface of the drainage plate, and the lower surface of the drainage plate is connected to the inner bottom of the sewage collecting trough, and the bottom surface of the sewage collecting trough is inclined close to the grinding wheel.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The tooth mold repairing water grinder uses water sprayed from a water spray port to impact the surface of the grinding wheel. When the grinding wheel rotates at a high speed, water splashes onto the inner cavity surface through the rotation of the grinding wheel. The water on the inner cavity surface is collected by baffles 1 and 2 and guided to the surface of the water guide plate. At the same time, the water guide plate is arranged on one side of the grinding wheel surface, and the water dripping from the grinding wheel surface can also be collected synchronously. The water guide plate is curved and concave downward, so that the collected water flows quickly from top to bottom in the sewage collection tank. Since the upper surface of the water guide plate is correspondingly connected to the filter plate, the debris generated by the tooth mold repairing can be collected and It is washed away from the surface of the water guide plate along with the water flow, and then contacts the surface of the drainage plate. Because a partition is provided on the upper surface of the drainage plate, it can effectively prevent water and debris from directly impacting the inner wall of the sump, causing the debris to stick to the inner wall of the sump. Finally, because the bottom surface of the sump is inclined close to the grinding wheel side, the water mixed with debris can flow out from the inside of the sump to prevent the accumulation of debris inside the sump. The water grinder needs to be opened regularly to split the grooves so that the debris accumulated inside the grooves can be cleaned up, so as to achieve the effect of cleaning the debris while repairing the tooth mold.

DETAILED DESCRIPTION

[0016] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1 - Figure 7 As shown, the purpose of this embodiment is to provide a water grinder for tooth mold repair, including a control box 100, a mold repair mechanism 200 and a dirt collecting tank 300, the control box 100 includes a front cover 102, a mold repair port 103 and a collection box 104, one side of the surface of the front cover 102 is rotatably connected with a hinge 101, the front cover 102 is opened and closed on the surface of the control box 100 by the hinge 101, and the inner bottom of the collection box 104 is correspondingly connected to the surface of the mold repair port 103.

[0018] The mold repairing mechanism 200 includes a grinding wheel 201, an inner cavity 206 and a water spray assembly. The grinding wheel 201 rotates inside the mold repairing port 103 through the control box 100. The water spray assembly is fixedly installed on the surface of the inner cavity 206, and one side of the water spray assembly extends to the bottom of the back of the grinding wheel 201. The sewage collecting trough 300 includes a water guide plate 301 and a drainage plate 305. The water guide plate 301 is fixedly installed on the top of the inner side of the sewage collecting trough 300, and the drainage plate 305 is fixedly installed on the bottom of the inner side of the sewage collecting trough 300.

[0019] Through the operation of the control box 100, the driving shaft drives the grinding wheel 201 to rotate at a high speed, and the water spray component sprays water from the lower surface of the back of the grinding wheel 201. The staff attaches the tooth mold to the surface of the grinding wheel 201 through the mold repairing port 103, and performs mold repair on the surface of the tooth mold. The debris generated during the mold repairing process falls into the sewage collection tank 300. The grinding wheel 201 can effectively concentrate the water dripping from the lower surface and part of the splashing water on the upper surface of the water guide plate 301 by rotating at a high speed, so that the water flows rapidly on the upper surface of the water guide plate 301. Since there is debris accumulated on the upper surface of the water guide plate 301, the water flow can be used to wash away the debris accumulated on the upper surface of the water guide plate 301, so as to reduce the accumulation of debris inside the sewage collection tank 300, and finally the water with debris is discharged from the inside of the device through the provided sewage pipe 304.

[0020] Based on the above structure, combined with Figure 1 As shown, the structure of the control box 100 is further disclosed. A sewage outlet 106 is opened on one side of the lower surface of the front cover 102. The sewage outlet 106 is connected to the sewage pipe 304 accordingly. A filter plate 105 is movably connected to the upper surface of the collection box 104.

[0021] Furthermore, the front cover 102 is clamped on the surface of the control box 100 by the hinge 101, and the driving assembly arranged inside the control box 100 drives the grinding wheel 201 to rotate at high speed. Since the front end surface of the grinding wheel 201 and the surface of the mold repairing port 103 correspond to each other, the staff can hold the tooth mold and grind the surface of the mold repairing port 103 with the surface of the grinding wheel 201. The generated debris can fall into the sewage collecting tank 300 through the filter holes opened in the filter plate 105. After the debris is taken away from the lower surface of the mold repairing port 103 by water flow, the debris and water are discharged from the inside of the device together through the sewage outlet 106 and the sewage pipe 304.

[0022] Based on the above structure, combined with Figure 2 and Figure 5 As shown, the structure of the water spray assembly is further disclosed. The water spray assembly includes a docking port 204, a water pipe 203 is fixedly installed on the lower surface of the docking port 204, a socket 202 is fixedly sleeved on the lower surface of the water pipe 203, and a water spray port 205 is opened on one side of the surface of the socket 202.

[0023] Furthermore, the pipe for conveying water from the outside can be passed through the inner cavity 206 through the opened docking port 204, and fixedly sleeved on the upper surface of the water pipe 203. After the water is transported to the inside of the water pipe 203, the sleeve connection function of the sleeve 202 is utilized to make the water spray out from one side of the water spray port 205. Since the water spray port 205 is provided on the lower surface of the back of the grinding wheel 201, when the grinding wheel 201 rotates at a high speed, the water sprayed from the water spray port 205 can rinse the lower surface of the back of the grinding wheel 201. Under the action of centrifugal force, the water is effectively splashed inside the device as the grinding wheel 201 rotates at a high speed. When the grinding wheel 201 stops rotating, the water will flow on the lower surface of the back of the grinding wheel 201, which is convenient for the subsequent centralized collection of water and the transmission to the inside of the sewage collecting tank 300 to clean the inside of the sewage collecting tank 300.

[0024] Therefore, based on the above structure, combined with Figure 3-Figure 4 and Figure 6-Figure 7 The structure of the flow collecting assembly is further disclosed as shown. The sewage collecting tank 300 includes a water guide plate 301 and a drainage plate 305. The water guide plate 301 is fixedly installed on the top of the inner side of the sewage collecting tank 300, and the drainage plate 305 is fixedly installed on the bottom of the inner side of the sewage collecting tank 300.

[0025] Furthermore, as the grinding wheel 201 rotates at high speed, the water sprayed from the water nozzle 205 splashes around the inside of the device as the grinding wheel 201 rotates at high speed. Part of the splashed water flows on the surface of the inner cavity 206. The baffle 1 302 and the baffle 2 303 arranged on one side can guide and collect the water flowing on the surface of one side of the inner cavity 206, and transmit it to the upper surface of the water guide plate 301.

[0026] The water guide plate 301 is curved and concave downward. The designed curved concave can effectively accelerate the flow rate of water, and at the same time, it has a certain diversion effect on the water guided at both ends of the baffle plate 1 302 and the baffle plate 2 303, and converges at the concave to flow downward, and the small concave can slow down the water flowing from the bottom of the water guide plate 301 and the collision speed with the surface of the guide plate 305, so as to avoid the debris splashing with the water flow due to excessive impact of the water flow, and the debris on the surface of the water guide plate 301 flows downward with the water flow, and because the upper surface of the water guide plate 301 is connected to the filter plate 105 correspondingly, the debris generated by the repair of the tooth mold can be collected and carried away with the water flow. The debris is washed away from the surface of the water guide plate 301 and contacts the surface of the drainage plate 305. Because the upper surface of the drainage plate 305 is provided with a partition, it can effectively prevent water and debris from directly impacting the inner wall of the sump 300, causing the debris to stick to the inner wall of the sump 300. Finally, because the bottom surface of the sump 300 is inclined close to the grinding wheel 201, the water mixed with debris can flow out from the inside of the sump 300 to prevent the debris from accumulating inside the sump 300. The water mill needs to be opened regularly to split the grooves before the debris accumulated inside the grooves can be cleaned up, so as to achieve the effect of cleaning the debris while repairing the tooth mold.

[0027] It should be noted that: compared with the prior art, the debris generated by the repair of the tooth mold falls into the sump 300 through the filter plate 105, while the present invention uses the water guide plate 301 to collect the debris, and when the grinding wheel 201 rotates at a high speed, it drives water to splash in the inner cavity 206. The baffle 1 302 and the baffle 2 303 are set to guide the water on the surface of the inner cavity 206. At the same time, the two sides of the upper surface of the water guide plate 301 correspond to the baffle 1 302 and the baffle 2 303, and one side of the upper surface of the water guide plate 301 corresponds to the surface of the grinding wheel 201. Therefore, the water guide plate 301 can collect the water guided by the baffle 1 302 and the baffle 2 303, as well as the water on the surface of the grinding wheel 201, and the debris collected on the surface of the water guide plate 301 is rinsed by the collected water.

[0028] The surface of the water guide plate 301 is provided with micro-textures, the direction of which is consistent with the direction of water flow, which effectively reduces the contact area between debris and the surface of the water guide plate 301, reduces the possibility of debris adhesion, and at the same time guides the water guided by baffle 1 302 and baffle 2 303, reduces the mutual collision force between the water guided by baffle 1 302 and baffle 2 303, and affects the water cleaning of debris.

[0029] To sum up, the working principle of this scheme is as follows: the driving shaft installed inside the control box 100 runs, driving the grinding wheel 201 to rotate at high speed, and the staff holds the tooth mold from the mold repairing port 103 and contacts the surface of the grinding wheel 201 to perform mold repair on the tooth mold. The generated debris can fall into the sewage collection tank 300 through the set filter plate 105.

[0030] When the grinding wheel 201 rotates at a high speed, the opening 204 can allow the external water pipeline to pass through the inner cavity 206 and be fixedly sleeved on the upper surface of the water pipe 203 to spray water from the water spray port 205. Since the water spray port 205 is arranged on the lower surface of the back of the grinding wheel 201, when the grinding wheel 201 rotates at a high speed, water will splash as the grinding wheel 201 rotates, which can cool the surface of the grinding wheel 201 on the one hand and prevent debris from accumulating on the surface of the grinding wheel 201 on the other hand.

[0031] When water splashes with the high-speed rotation of the grinding wheel 201, some water droplets will drip onto the surface of the inner cavity 206 through the centrifugal force of the grinding wheel 201. The water droplets dripping from the surface of the inner cavity 206 are guided and collected by the baffle plate 1 302 and the baffle plate 2 303, and concentrated on the upper surface of the water guide plate 301. Since the upper surface of the water guide plate 301 and the surface of the filter plate 105 are correspondingly connected, the debris generated by the repair of the tooth mold can be directly dropped onto the surface of the water guide plate 301 through the filter plate 105, and then the debris can flow on the surface of the water guide plate 301 together with the water flow, and be transmitted to the surface of the drainage plate 305, and generate collision with the surface of the drainage plate 305. On the one hand, it can prevent the debris from directly contacting the inner wall of the sewage collecting tank 300. On the other hand, since a partition is arranged above the drainage plate 305, it can ensure that the water flow impacts the surface of the drainage plate 305, which has a blocking effect on the water flow and prevents the debris from sticking to the surface of the drainage plate 305. As the water flow and the drainage plate 305 are drawn out from the inside of the sewage collecting tank 300 and discharged from the sewage pipe 304, the sewage pipe 304 and the sewage outlet 106 are connected to each other. Since the sewage outlet 106 is connected to an external pipeline, the water with debris is discharged from the inside of the device, so as to achieve the effect of synchronously cleaning the debris during the tooth mold repair process.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
