Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

Fig. 1 is a schematic view showing a structure of a denture polishing apparatus according to an embodiment of the present application. As shown in fig. 1, the denture polishing apparatus 100 may include an air reservoir 110, an air nozzle 120, a pressure regulating valve 210, and a polishing bath 130. The air tank 110 is used to store compressed air. The gas injection pipe 120 has a gas inlet 120A and a gas outlet 120B, and the gas inlet 120A of the gas injection pipe 120 communicates with the gas outlet 110B of the gas storage tank 110 for receiving the compressed air, for example, the gas inlet 120A of the gas injection pipe 120 communicates with the gas outlet 110B of the gas storage tank 110 through a first delivery pipe 310, and preferably, the first delivery pipe 310 is a hose for facilitating the user to move the gas injection pipe 120. The pressure regulating valve 210 is disposed at the air outlet 110B of the air storage tank 110, and is used for regulating the pressure of the compressed air delivered to the air injection pipe 120, so that the compressed air is injected through the air injection port 120B of the air injection pipe 120 according to a desired pressure. Polishing bath 130 is configured to contain polishing liquid 131 having a plurality of polishing abrasive particles 131A and a denture 132, each polishing abrasive particle 131A having a different particle size, denture 132 adapted to be submerged in polishing liquid 131. Wherein the air nozzle 120B of the air nozzle 120 is adapted to extend into the polishing liquid 131 and locate the denture 132 in the spray area S1 of the air nozzle 120B, and in the case that compressed air is sprayed toward the denture 132 through the air nozzle 120B, the compressed air pushes the polishing abrasive particles 131A adapted to the pressure thereof to move toward the surface of the denture 132, and fig. 1 shows only a part of the polishing abrasive particles 131A in the polishing liquid 131.

Illustratively, the polishing abrasive particles 131A include two or more kinds, and the pressure of the compressed air delivered to the air nozzle 120 is adjusted to push the polishing abrasive particles 131A with larger particle size to move towards the surface of the denture 132 when the compressed air is ejected from the air nozzle 120B, so as to roughly polish the surface of the denture 132, and thus, the protrusions with larger surface area on the surface of the denture 132 can be quickly removed; by reducing the pressure of the compressed air supplied to the air nozzle 120, the compressed air is ejected through the air nozzle 120B to push the polishing abrasive particles 131A with smaller particle size to move toward the surface of the prosthetic appliance 132, thereby finely polishing the surface of the prosthetic appliance 132, and thus, the protrusions with smaller surface area on the surface of the prosthetic appliance 132 can be removed.

Preferably, the polishing bath 130 may be a transparent polishing bath so as to observe the depth of the polishing liquid 131 and the positions of the prosthetic appliance 132, the air nozzle 120B, and the like in the polishing liquid 131 during operation.

Illustratively, the polishing solution 131 may be a polishing solution commonly used in the art, and generally consists of polishing abrasive particles 131A, a water-based solution and a high polymer additive, wherein the polishing solution 131 is colloidal as a whole, and the polishing abrasive particles 131A are suspended in the polishing solution 131. The material of the polishing abrasive particles 131A may be a material having a high hardness, such as cerium oxide or silicon oxide. The hardness of the polishing abrasive particles 131A is greater than that of the prosthetic appliance 132. In the prior art, when the grinding head is used for polishing and grinding the surface of the denture, the grinding head is controlled by a user to contact with the surface of the denture and apply pressure to the surface of the denture by using the grinding head, and if the pressure applied by the user is large, the surface of the denture is easily damaged unnecessarily. The denture polishing device 100 according to the embodiment of the present application can avoid such unnecessary damage in the prior art by spraying compressed air into the colloidal polishing solution 131 and pushing the polishing abrasive particles 131A in the polishing solution 131 with the compressed air to polish and polish the surface of the denture 132.

Illustratively, the type of the denture 132 includes, but is not limited to, removable dentures, fixed dentures, crowns, and the like, and the denture 132 includes, but is not limited to, resin, metal, all-ceramic, and the like, wherein the metal includes gold, cobalt-chromium alloy, nickel-chromium alloy, copper alloy, and the like. The number of the dentures 132 may be a single denture or two or more dentures arranged in a row. The type, material and number of the dentures 132 in the embodiment of the present application can be selected and adjusted according to actual needs, which is not limited in the embodiment of the present application.

When the denture polishing device 100 according to the embodiment of the present application is used for polishing the surface of the denture 132, the pressure regulating valve 210 regulates the pressure of the compressed air delivered to the air jet pipe 120, so that the compressed air can be jetted to the denture 132 through the air jet 120B according to the required pressure, thereby pushing the polishing abrasive particles 131A adapted to the pressure of the compressed air to move on the surface of the denture 132, and polishing the surface of the denture 132 at different polishing levels.

It should be noted that, in the prior art, the grinding head is usually adapted to the polishing level of the denture by replacing the grinding heads with different granularities, and since the grinding head is used to polish the surface of the denture, the grinding head is worn away, so that the grinding head needs to be replaced periodically, which is costly to use. Compared with the prior art, the denture polishing device 100 of the embodiment of the application adapts to different polishing levels by adjusting the pressure of the compressed air, so that the gas nozzle 120 hardly wears, and therefore, the gas nozzle 120 does not need to be replaced regularly and in a large amount, and the use cost can be reduced.

In one embodiment, the denture polishing apparatus 100 further comprises a first up signal generating module 220, a first down signal generating module 230, and a controller 240. The first up signal generating module 220 is configured to generate a first up signal, the first down signal generating module 230 is configured to generate a first down signal, and the controller 240 is connected to the first up signal generating module 220, the first down signal generating module 230, and the pressure regulating valve 210. The controller 240 is configured to send a first increase command to the pressure regulating valve 210 to cause the pressure regulating valve 210 to increase the delivery pressure of the compressed air, if the first increase signal is received. The controller 240 is further configured to send a first lowering command to the pressure regulating valve 210 to cause the pressure regulating valve 210 to lower the delivery pressure of the compressed air, if the first lowering signal is received.

In one example, the first up signal generating module 220 may be a first pedal and the first down signal generating module 230 may be a second pedal. In the polishing process of the prosthetic appliance 132, the prosthetic appliance 132 and the gas nozzle 120 are generally held by both hands of the user, respectively, and different positions of the surface of the prosthetic appliance 132 are polished by adjusting the relative position between the gas nozzle 120B of the gas nozzle 120 and the surface of the prosthetic appliance 132, so that the adjustment operation of the pressure adjusting valve 210 is inconvenient for both hands of the user. The first pedal is trampled to generate a first heightening signal, and the second pedal is trampled to generate a first lowering signal, so that the adjustment operation is convenient.

It is understood that the first up signal generating module 220 and the first down signal generating module 230 may also be a knob, a button, etc., and the embodiment of the present application does not limit the type and arrangement of the first up signal generating module 220 and the first down signal generating module 230.

In the above solution, the first up signal generating module 220 is arranged to generate a first up signal, so that the first up signal triggers the controller 240 to send a first up command to the pressure regulating valve 210, so that the pressure regulating valve 210 automatically increases the pressure of the compressed air delivered to the gas ejector 120; and, the first lowering signal generating module 230 is configured to generate a first lowering signal, so that the first lowering signal triggers the controller 240 to send a first lowering command to the pressure regulating valve 210, so that the pressure regulating valve 210 automatically lowers the pressure of the compressed air delivered to the gas nozzle 120. Therefore, convenience of pressure regulating operation is improved.

In one embodiment, the denture polishing apparatus 100 further comprises an ultrasonic transducer 250. The ultrasonic transducer 250 is used for emitting ultrasonic waves to the inside of the polishing pool 130, the ultrasonic waves are used for generating cavitation bubbles (not shown in the figure) in the polishing liquid 131, and the generation area S2 of the cavitation bubbles at least partially coincides with the spraying area S1.

In an alternative example, as shown in fig. 1, the ultrasonic transducer 250 may be sleeved on the periphery of the gas lance 120, as shown in fig. 2, the ultrasonic transducer 250 may also be disposed on the sidewall or the bottom wall of the polishing pool 130, as long as it is ensured that the generation region S2 where the ultrasonic transducer 250 excites the polishing liquid 131 to form cavitation bubbles at least partially coincides with the injection region S1.

In one example, the denture polishing apparatus 100 further comprises a power supply (not shown) connected to the ultrasonic transducer 250 and the controller 240, respectively, to supply power to the ultrasonic transducer 250 and the controller 240.

For example, the process of ultrasonically exciting the polishing liquid 131 to generate cavitation bubbles may be: when the ultrasonic transducer 250 emits ultrasonic waves toward the inside of the polishing pool 130, a tensile stress locally occurs in the polishing liquid 131 under the action of the ultrasonic waves to form a negative pressure, and the reduction of the local pressure in the polishing liquid 131 supersaturates the micro bubbles originally dissolved in the polishing liquid 131 and allows the micro bubbles to escape from the polishing liquid 131 to form a large amount of cavitation bubbles. Then, under the action of ultrasonic wave, the cavitation bubbles vibrate, grow, shrink and collapse and close rapidly, and great instantaneous pressure is released.

According to the scheme, the generation area S2 of the cavitation bubbles is at least partially overlapped with the injection area S1 of the air nozzle 120B, and the compressed air injected by the air nozzle 120B can be used for pushing the cavitation bubbles to move towards the surface of the denture 132, so that the cavitation bubbles are promoted to release instantaneous high pressure on the surface of the denture 132, and the high pressure generated by the cavitation bubbles acts on the surface of the denture 132 to polish the surface of the denture 132. Therefore, the artificial tooth surface can be polished based on ultrasonic cavitation and polishing abrasive particle impact, double polishing effects are achieved, and polishing efficiency is improved.

In one embodiment, the frequency of the ultrasonic wave emitted by the ultrasonic transducer 250 ranges from 10KHz to 130KHz (inclusive), for example, the frequency of the ultrasonic wave may be any one of 10KHz, 20KHz, 30KHz, … …, 100KHz, … … and 130 KHz.

The denture polishing apparatus 100 also includes a second up signal generating module 260 and a second down signal generating module 270. The second up signal generating module 260 is configured to generate a second up signal. The second turn-down signal generating module 270 is configured to generate a second turn-down signal. The controller 240 is connected to the second up signal generating module 260, the second down signal generating module 270 and the ultrasonic transducer 250, respectively. The controller 240 is configured to send a second up command to the ultrasonic transducer 250 to enable the ultrasonic transducer 250 to increase the frequency of the ultrasonic wave when receiving the second up signal; the controller 240 is further configured to send a second down command to the ultrasonic transducer 250 to enable the ultrasonic transducer 250 to lower the frequency of the ultrasonic wave if the second down signal is received.

For example, the second up signal generating module 260 and the second down signal generating module 270 may be a knob, a button, a pedal, and the like, and the embodiments of the present application do not limit the types of the second up signal generating module 260 and the second down signal generating module 270. Preferably, the second up signal generating module 260 is a third pedal and the second down signal generating module 270 is a fourth pedal. The second step-up signal is generated by stepping on the third pedal, and the second step-down signal is generated by stepping on the fourth pedal, so that the adjustment operation is convenient.

In the above scheme, the second up signal generating module 260 is arranged to generate a second up signal, and the second up signal can be used to trigger the controller 240 to send a second up command to the ultrasonic transducer 250, so that the ultrasonic transducer 250 increases the frequency of the ultrasonic wave; and, by setting the second turn-down signal module to generate a second turn-down signal, the second turn-down signal may be used to trigger the controller 240 to send a second turn-down instruction to the ultrasonic transducer 250, so that the ultrasonic transducer 250 increases the frequency of the ultrasonic wave. Therefore, the automatic adjustment of the ultrasonic frequency can be realized, and the frequency of the ultrasonic is matched with the generation of the cavity bubbles.

In one embodiment, the denture polishing apparatus 100 further comprises an air compressor 140 and a first air pressure sensor 281. The air outlet of the air compressor 140 is communicated with the air inlet 110A of the air storage tank 110 through a second transmission pipe 320, and the air compressor 140 can compress the air to generate compressed air and deliver the compressed air to the air storage tank 110. The first air pressure sensor 281 may be disposed inside the air tank 110 for detecting the air pressure inside the air tank 110. The air compressor 140 and the first air pressure sensor 281 are respectively connected to the controller 240, and the controller 240 is further configured to send a stop command to the air compressor 140 to stop the operation of the air compressor 140 when the air pressure of the air storage tank 110 exceeds an air pressure threshold. In this way, when the air pressure inside the air storage tank 110 exceeds the air pressure threshold, the air compressor 140 can be automatically controlled to stop running, so that the air compressor 140 stops delivering the compressed air to the air storage tank 110, the air storage tank 110 is protected by overpressure, and the safety of the compressed air stored in the air storage tank 110 is improved.

In one embodiment, the denture polishing apparatus 100 further comprises a second air pressure sensor 282 and a display screen 290. The second air pressure sensor 282 is used for detecting the pressure of the compressed air ejected from the air nozzle 120, and the controller 240 is connected to the second air pressure sensor 282. Since the air outlet 110B of the air tank 110 is communicated with the air inlet of the air injection tube 120 through the first delivery pipe 310, and the compressed air pressure-regulated by the pressure regulating valve 210 has the same pressure in the first delivery pipe 310 and the air injection tube 120, the second air pressure sensor 282 may be disposed in the first delivery pipe 310, and the second air pressure sensor 282 may be disposed in the air injection tube 120.

The display screen 290 is connected to the controller 240 for receiving and displaying the pressure of the air in the air storage tank 110 and the pressure of the compressed air ejected from the air ejecting pipe 120, so that the user can check the pressure at any time.

In one embodiment, the denture polishing apparatus 100 further comprises a filter 150, wherein the filter 150 is disposed between the air outlet of the air compressor 140 and the air inlet 110A of the air tank 110, and is used for filtering the compressed air generated by the air compressor 140, so as to deliver the filtered compressed air to the air tank 110, thereby improving the cleanliness of the compressed air.

In one embodiment, the denture polishing apparatus 100 further comprises a check valve 160, and the check valve 160 is disposed between the air outlet of the air compressor 140 and the air inlet 110A of the air tank 110, so that compressed air can be delivered only from the air compressor 140 to the air tank 110, preventing the compressed air from flowing backwards.

In one embodiment, as shown in fig. 1, the polishing pool 130 has an operation opening 130A formed in a sidewall thereof, and the denture polishing apparatus 100 further includes a telescopic tube 410, a rubber glove 420, and an elastic ring 430. A first end of the extension tube 410 is communicated with the operation opening 130A, and a second end of the extension tube 410 extends into the polishing pool 130. The cuff of the rubber glove 420 is sleeved on the second end of the extension tube 410, and the rubber glove 420 is located inside the polishing pool 130. The elastic band 430 is used to tighten the cuff of the rubber glove 420 with the second end of the extension tube 410, and the elastic band 430 includes, but is not limited to, a rubber band.

When the denture polishing device 100 according to the embodiment of the present application is used to perform a polishing operation on the denture 132, a user can sequentially insert one hand into the rubber glove 420 through the operation opening 130A and the extension tube 410, so as to wear the rubber glove 420, and when holding the denture 132, the rubber glove 420 is in contact with the denture 132 and the polishing solution 131 inside the polishing pool 130, so as to prevent the polishing solution 131 from directly contacting the hand, and protect the hand. Moreover, compared with the case that both hands extend into the polishing pool 130 from the opening 130B of the polishing pool 130, one hand extends into the polishing pool 130 through the side wall of the polishing pool 130, and the other hand extends into the polishing pool 130 from the opening 130B of the polishing pool 130, the polishing effect can be observed more easily. Moreover, since the opening of the rubber glove 420 is sleeved on the second end of the extension tube 410, the extension and contraction of the extension tube 410 facilitates the movement of the hand inside the polishing pool 130, thereby improving the convenience of operation.

In one embodiment, the bottom of the polishing bath 130 is provided with a drain 440, and the drain 440 is provided with a manual valve 441. Illustratively, the drain pipe 440 is in communication with the polishing reservoir 130, and the polishing solution 131 inside the polishing reservoir 130 can be drained by opening the manual valve 441, so as to facilitate replacement of the polishing solution 131.

In one embodiment, referring to fig. 3 and 4, the gas nozzle 120 includes a gas nozzle body 121 and a nozzle 122, which are connected to each other, wherein the gas inlet of the gas nozzle body 121 forms a gas inlet 120A of the gas nozzle 120, the inner diameter of the nozzle 122 is adjustable, and the gas outlet of the nozzle 122 forms a gas outlet 120B of the gas nozzle 120.

According to the above-mentioned scheme, the inner diameter of the nozzle 122 is adjusted to adjust the air outlet area of the air nozzle 120B to match the concave portion and the convex portion with different sizes on the surface of the denture 132, so that the compressed air pushes the polishing abrasive particles 131A to fully contact the surface of the denture 132, for example, the occlusal surface of the denture 132, so that the polishing abrasive particles 131A fully polish the ravines of the occlusal surface of the denture 132, and the polishing effect can be improved.

In the related art, since the occlusal surface of the denture has an irregular gully shape, it is generally polished by using a polishing head having a shape such as a frustum, cone, or olive, and the polishing effect is highly sensitive because the user needs to select an appropriate polishing head based on medical experience and depends on the manipulation and control of the user. Compared with the prior art, the denture polishing device 100 of the embodiment of the application does not need to select a grinding head, is simple in polishing operation, reduces medical experience and technical requirements on users, and is low in technical sensitivity.

In one embodiment, referring to fig. 3 and 4 together, the nozzle 122 includes a plurality of nozzle bodies 122A, each nozzle body 122A is adapted to be detachably disposed at the gas outlet of the gas lance body 121 in sequence along the axial direction of the gas lance body 121, and the inner diameters of the plurality of nozzle bodies 122A decrease along the axial direction of the gas lance body 121. As such, by increasing the number of nozzle bodies 122A, the inner diameter of the nozzle 122 can be reduced; by reducing the number of nozzle bodies 122A, the inner diameter of the nozzle 122 can be increased, enabling adjustment of the inner diameter of the nozzle 122. For example, one nozzle body 122A is provided at the gas outlet of the gas nozzle body 121 in fig. 3, three nozzle bodies 122A are provided at the gas outlet of the gas nozzle body 121 in fig. 4, and the inner diameter of the nozzle 122 constituted by the three nozzle bodies 122A in fig. 4 is smaller than the inner diameter of the nozzle 122 constituted by one nozzle body 122A in fig. 3.

Illustratively, when one nozzle body 122A is provided at the gas outlet of the gas lance body 121, the gas outlet of the nozzle body 122A constitutes a gas injection port 120B of the gas lance 120; when the plurality of nozzle bodies 122A are sequentially provided at the gas outlet of the gas ejector body 121, the gas outlet of the nozzle body 122A, which is distant from the gas ejector 120, constitutes a gas ejection port 120B of the gas ejector 120.

In one embodiment, the gas lance body 121 is cylindrical, such as cylindrical, rectangular cylindrical, elliptical cylindrical, etc., having the same cross-sectional area. Each nozzle body 122A is a cylinder having a cross-sectional area that decreases in the axial direction of the gas lance body, for example, each nozzle body 122A has an inverted conical cylinder shape. In the axial direction of the gas lance body 121, the outer contour dimension of each nozzle body 122A is gradually decreased. Such a structure is not only convenient for a user to hold, but also can make the outer contour of the nozzle 122 slimmer when increasing the number of the nozzle bodies 122A, so as to improve the alignment between the air nozzle 120B and the region to be polished on the surface of the denture 132, and to facilitate the improvement of the polishing accuracy.

In one embodiment, the abrasive polishing particles 131A include first abrasive polishing particles having a particle size ranging from 3 μm to 5 μm inclusive and second abrasive polishing particles having a particle size ranging from 30 μm to 50 μm inclusive. For example, the particle diameter of the first abrasive grain 1 may be any one of 3 μm, 4 μm, and 5 μm, and the particle diameter of the second abrasive grain may be any one of 30 μm, 35 μm, 40 μm, 45 μm, and 50 μm.

Other configurations of the denture polishing apparatus 100 of the above-described embodiments may be adopted by various technical solutions known to those skilled in the art now and in the future, and will not be described in detail herein.
