Description

Technical Field

[0001] This application relates to the field of dental grinding technology, and for example to a dental grinding device. Background Technology

[0002] Currently, in the field of denture grinding technology, denture grinding equipment relies on a water system to complete the cooling and washing of grinding debris during the grinding process. The water tank, as the core water storage component of the water system, directly impacts the overall efficiency of the equipment due to the ease of its water change operation. Early denture grinding equipment typically used an integrated, fixed connection design between the water tank and the water system. This meant the water tank was rigidly connected to the grinding components, water pump, and other key parts via water pipes. This connection method required operators to disassemble the connecting water pipes or remove the water pump and other related components each time the water needed to be changed. This not only increased the complexity of the operation but could also affect the stability of the water system connection during disassembly, leading to increased equipment maintenance costs and significantly reducing the ease of use and daily maintenance efficiency of the denture grinding equipment.

[0003] To address the cumbersome water change process caused by the fixed connection of the water tank, a detachable water circuit connection structure has been developed in related technologies. This type of structure designs the connection between the water tank and the water circuit system as a pluggable type, allowing the water tank to be removed from the equipment independently without disassembling other components such as water pipes and pumps. This effectively simplifies the water change process, shortens the water change time, and improves the efficiency of the equipment to some extent. In terms of sealing design, the detachable connection structures in related technologies mostly adopt a planar contact sealing solution. For example, by setting up components such as planar rubber sealing gaskets and planar one-way valves, the sealing components are tightly fitted by the pressure during connection, thereby achieving a seal in the water circuit and preventing water leakage during normal equipment operation.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: The planar contact sealing method used in the relevant technology has high requirements for water quality. Furthermore, the fine ceramic dust particles generated during denture grinding are extremely small and easily adhere to the contact area of ​​the sealing surface, disrupting the tight fit and causing sealing performance failure. When the operator removes the water tank, the failed seal at the joint cannot effectively block water flow, leading to leakage. This fails to meet the reliability requirements for water connection structure sealing in denture grinding scenarios.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0009] Optionally, the water outlet connection device includes: a water outlet component, comprising a first channel and a second channel arranged along the water outlet direction, wherein the projection of the first channel along the water outlet direction is located within the projection range of the second channel along the water outlet direction, the first channel and the second channel together form a water outlet channel, and a spherical body is located within the second channel and can slide linearly along the second channel; wherein, when the water outlet connection device is in a non-advancing state, the spherical body is located in the initial position and is subjected to at least an elastic force, blocking the first channel, at which time the first channel and the second channel are not connected; when the water outlet connection device is in an advancing state, the spherical body leaves the initial position and is subjected to at least a greater elastic force than when it is in the initial position, at which time the first channel and the second channel are connected.

[0010] Optionally, the water outlet connection device further includes: a water inlet component, including at least one water inlet channel, through which water in the water tank can flow into the water outlet channel; and an elastic component, one end of which is a spherical body providing elastic force, and the other end abutting against the water inlet component.

[0011] Optionally, the water inlet component includes: a guide post extending into the water outlet channel; and a water inlet head formed by a radially protruding section at the tail of the guide post; wherein the projection of the guide post along the water outlet direction is located within the projection range of the water inlet head along the water outlet direction, and at least one water inlet channel is provided on the water inlet head and / or the guide post, allowing water in the water tank to flow into the water outlet channel from at least one water inlet channel.

[0012] Optionally, at least one water inlet channel is provided only inside the water inlet head, and the elastic element is sleeved outside the guide post and abuts against the water inlet head.

[0013] Optionally, at least one water inlet channel is provided only inside the guide column, and the elastic element is sleeved outside the guide column and abuts against the water inlet head; or, at least one water inlet channel is provided only inside the guide column, and the elastic element is provided inside at least one water inlet channel and abuts against the limiting wall provided inside at least one water inlet channel.

[0014] Optionally, at least one water inlet channel is provided inside both the water inlet head and the guide column, and the elastic element is sleeved outside the guide column and abuts against the water inlet head; or, at least one water inlet channel is provided inside both the water inlet head and the guide column, and the elastic element is provided inside at least one water inlet channel and abuts against the limiting wall provided inside at least one water inlet channel.

[0015] Optionally, multiple water inlet channels within the water inlet head are evenly arranged around the water outlet direction; and at least one water inlet channel within the guide column is located within the area enclosed by the multiple water inlet channels within the water inlet head along the water outlet direction.

[0018] The dental grinding device provided in this disclosure can achieve the following technical effects: When the water outlet connection device is not pushed in, the spherical body maintains its initial position under the action of elastic force, forming a linear contact seal with the water outlet channel, thereby blocking the water flow. Compared with planar seals, the linear contact method is more adaptable to changes in water quality. Even in the presence of fine ceramic dust, the soft nature of the spherical body can push the dust out during sliding and tightly block the water outlet, ensuring reliable sealing. When water flow is needed, the spherical body is pushed away from its initial position, compressing the elastic element, opening the water passage, and allowing water to flow through. The elastic force always acts on the spherical body, causing it to automatically reset after the external thrust disappears, thus simplifying the insertion and removal of the water tank, avoiding the cumbersome steps of disassembling water pipes under traditional fixed connection methods, and improving equipment maintenance efficiency and ease of use.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0030] Combination Figure 1-7As shown, this embodiment of the present disclosure provides a denture grinding device, including a grinding assembly, a water tank 10, and a water outlet connection device 20. The grinding assembly is used to grind dentures; the water tank 10 is connected to the grinding assembly via a water passage; the water outlet connection device 20 is disposed on the water passage and connected to the water tank 10, including a water outlet channel and a spherical body 26 disposed within the water outlet channel and capable of linearly sliding along the water outlet direction. When the spherical body 26 is in its initial position, the water outlet connection device 20 is in a non-advanced state, and the spherical body 26 prevents water in the water tank 10 from flowing out of the water outlet channel; when the spherical body 26 linearly slides away from the initial position, the water outlet connection device 20 is in an advanced state, water in the water tank 10 can flow out from the water outlet channel, and the spherical body 26 is subjected to an elastic force that causes the spherical body 26 to at least return to its initial position.

[0031] In this embodiment, the spherical body 26 can be a rubber ball.

[0032] Using the denture grinding device provided in this embodiment, when the water outlet connection device 20 is not pushed in, the spherical body 26 maintains its initial position under the action of elastic force, forming a linear contact seal with the water outlet channel, thereby blocking the water flow. The linear contact method is more adaptable to changes in water quality than a planar seal. Even in the presence of fine ceramic dust, the soft nature of the spherical body 26 can push the dust out during sliding and tightly block the water outlet, ensuring reliable sealing. When water flow is needed, the spherical body 26 is pushed away from its initial position, compressing the elastic element 25, thus opening the water passage and allowing water to flow. The elastic force always acts on the spherical body 26, causing it to automatically reset after the external thrust disappears, thereby simplifying the insertion and removal operation of the water tank 10, avoiding the cumbersome steps of disassembling water pipes under traditional fixed connection methods, and improving equipment maintenance efficiency and ease of use.

[0033] Optionally, the water outlet connection device 20 includes a water outlet component 21. The water outlet component 21 includes a first channel 211 and a second channel 212 arranged along the water outlet direction. The projection of the first channel 211 along the water outlet direction falls within the projection range of the second channel 212 along the water outlet direction. The first channel 211 and the second channel 212 together form the water outlet channel. The spherical body 26 is located within the second channel 212 and can slide linearly along the second channel 212. Specifically, when the water outlet connection device 20 is in a non-advanced state, the spherical body 26 is in its initial position and is subjected to at least an elastic force, blocking the first channel 211. At this time, the first channel 211 and the second channel 212 are not connected. When the water outlet connection device 20 is in an advanced state, the spherical body 26 leaves its initial position and is subjected to at least a greater elastic force than when it was in its initial position. At this time, the first channel 211 and the second channel 212 are connected.

[0034] Thus, when the water outlet connection device 20 is in the non-advanced state, the spherical body 26 is in its initial position under the action of elastic force, forming a linear contact seal with the first channel 211, thereby blocking the water flow. The linear contact method is more adaptable to changes in water quality than the planar seal, and the soft nature of the spherical body 26 can push out fine dust during sliding and tightly block the water outlet, improving the reliability of the seal. When the water outlet connection device 20 is in the advanced state, the spherical body 26 is pushed away from its initial position, compressing the elastic element 25, connecting the first channel 211 and the second channel 212, allowing water to flow through. The elastic force always acts on the spherical body 26 to ensure its automatic reset, thereby simplifying the insertion and removal operation of the water tank 10.

[0035] Optionally, the water outlet connection device 20 further includes a water inlet 22 and an elastic element 25. The water inlet 22 includes at least one water inlet channel 221, through which water in the water tank 10 can flow into the water outlet channel; one end of the elastic element 25 provides elastic force to the spherical body 26, and the other end abuts against the water inlet 22.

[0036] By adding an inlet component 22 and an elastic component 25 to the water outlet connection device 20, the reliability and ease of operation of the water circuit connection are further optimized. The inlet component 22, with at least one inlet channel 221, provides a clear inflow path for water in the water tank 10, ensuring that when the spherical body 26 is pushed away from its initial position, water can smoothly enter the outlet channel from the inlet channel 221, thus achieving controllable flow. Simultaneously, one end of the elastic component 25 provides elastic force to the spherical body 26, while the other end abuts against the inlet component 22, allowing the spherical body 26 to automatically return to its initial position under elastic force when not subjected to external pushing, forming a linear contact seal with the outlet channel. This not only enhances the stability of the seal but also pushes out any fine dust that may adhere to the spherical body 26 during its sliding process, reducing the impact of dust on the sealing performance. Therefore, while ensuring the quick insertion and removal function of the water tank 10, it improves adaptability to water quality and dusty environments and reduces the risk of leakage.

[0037] Optionally, the water inlet component 22 includes a guide post 222 and a water inlet head 223. The guide post 222 extends into the water outlet channel; the water inlet head 223 is formed by a radial protrusion at the tail of the guide post 222. The projection of the guide post 222 along the water outlet direction is located within the projection range of the water inlet head 223 along the water outlet direction. At least one water inlet channel 221 is provided on the water inlet head 223 and / or the guide post 222, allowing water in the water tank 10 to flow into the water outlet channel from at least one water inlet channel 221.

[0038] In this way, the guide post 222 extends into the water outlet channel, and the water inlet head 223 is formed by the radial protrusion of the tail of the guide post 222. Furthermore, the projection of the guide post 222 is located within the projection range of the water inlet head 223. This structure allows for more stable and aligned installation of the water inlet component 22 within the water outlet channel. By providing at least one water inlet channel 221 on the water inlet head 223, the guide post 222, or both, a stable and potentially multi-path inflow method is provided for the water in the water tank 10, ensuring that water flows smoothly into the water outlet channel when the spherical body 26 is pushed open. The radially protruding structure of the water inlet head 223 provides a reliable contact surface for the elastic element 25, maintaining the direction and stability of the elastic force applied by the elastic element 25 to the spherical body 26, ensuring reliable reset of the linear sliding seal of the spherical body 26 and effective opening and closing of the water path.

[0039] Optionally, at least one water inlet channel 221 is provided only inside the water inlet head 223, and the elastic member 25 is sleeved outside the guide post 222 and abuts against the water inlet head 223.

[0040] In this way, by placing at least one water inlet channel 221 solely within the water inlet head 223, and simultaneously fitting the elastic element 25 around the guide post 222 and abutting against the radially protruding water inlet head 223, the guide post 222 itself is structurally intact. Its main function is to provide precise guidance for the linear sliding of the spherical body 26, avoiding the potential impact on its structural strength and guiding stability that would result from opening channels in the guide post 222. Water enters through an independent channel located within the water inlet head 223, achieving separation of the water flow path from the guiding structure, which helps reduce potential interference from the water flow to the movement of the spherical body 26. The elastic element 25, fitted around the guide post 222 and abutting against the water inlet head 223, ensures a stable transmission path for the elastic force, acting directly on the spherical body 26. This ensures that the spherical body 26 can accurately and smoothly return to its initial sealing position after the propulsion phase ends, thereby improving the reliability of the entire water outlet docking device 20's operation and the stability of its seal.

[0041] Optionally, at least one water inlet channel 221 is provided only inside the guide post 222, and the elastic member 25 is sleeved outside the guide post 222 and abuts against the water inlet head 223; or, at least one water inlet channel 221 is provided only inside the guide post 222, and the elastic member 25 is provided inside at least one water inlet channel 221 and abuts against the limiting wall provided inside at least one water inlet channel 221.

[0042] In this way, by placing at least one water inlet channel 221 within the guide post 222 and using an elastic element 25 fitted outside the guide post 222 to abut against the water inlet head 223, a water flow path can be formed using the internal space of the guide post 222, resulting in a more compact structural layout. Simultaneously, the guide post 222 serves both to guide the linear sliding of the spherical body 26 and as the water inlet channel 221, simplifying the number of components. Water flows directly into the guide post 222, helping to reduce external interference, while the elastic element 25 applies external pressure, ensuring the stability of the spherical body 26's reset force. Placing the elastic element 25 within the water inlet channel 221 of the guide post 222 and abutting against the limiting wall further utilizes the internal space of the channel to accommodate the elastic element 25. This built-in design helps reduce the radial dimension of the entire device, achieving miniaturization. At the same time, the elastic element 25, constrained by the limiting wall, provides a more concentrated elastic force, ensuring the accuracy and reliability of the spherical body 26's reset. By optimizing the internal spatial layout and force transmission path, the functional integration and operational stability of the water outlet docking device 20 within a limited space have been improved.

[0043] Optionally, at least one water inlet channel 221 is provided in both the water inlet head 223 and the guide post 222, and the elastic member 25 is sleeved outside the guide post 222 and abuts against the water inlet head 223; or, at least one water inlet channel 221 is provided in both the water inlet head 223 and the guide post 222, and the elastic member 25 is provided in at least one water inlet channel 221 and abuts against the limiting wall provided in at least one water inlet channel 221.

[0044] In this embodiment, water enters the annular gap 213 between the outer periphery of the guide post 222 and the inner wall of the outlet channel through at least one inlet channel 221 in the inlet head 223, and then flows axially towards the sphere 26. This allows the water flow to be evenly distributed within the annular cross section, reducing the local flow velocity and minimizing the uneven wear of the ceramic powder on one side of the guide post 222. Meanwhile, the annular gap 213, as part of the water outlet channel, provides a continuous radial enclosure space for the elastic element 25. The elastic element 25 is uniformly cooled by the water flow, reducing the temperature rise and slowing down the fatigue rate. In addition, the flow path of the annular gap 213 is longer than that of the straight through-hole. Fine powder carried in the water flow can be thrown to the outer wall due to inertia during the flow, and some of it is deposited at the inlet of the annular gap 213 (after the water flows out from at least one water inlet channel 221 of the water inlet head 223, it first enters the inlet section of the annular gap. Due to the sudden expansion of the cross section and the decrease in flow velocity, some ceramic powder with greater inertia will first adhere to the starting position of the annular gap 213. Then, the cleaner water can continue to flow along the annular gap 213 to the sphere 26, thereby reducing dust on the sealing surface). This reduces the particles reaching the sealing surface, thereby reducing the risk of dust piling up the sphere 26 when not advancing, and keeping the line seal stable.

[0045] By providing at least one water inlet channel 221 within both the inlet head 223 and the guide post 222, a composite water inlet path is formed, increasing the cross-sectional area for water flow. This allows water to flow smoothly and simultaneously from both the inlet head 223 and the guide post 222 when the spherical body 26 is pushed open, increasing the water flow rate per unit time and meeting the cooling and rinsing water requirements of the grinding process. When the elastic element 25 is fitted outside the guide post 222 and abuts against the inlet head 223, the elastic force is transmitted through the inlet head 223, resulting in a simple, reliable structure that is easy to assemble and maintain. When the elastic element 25 is located within the inlet channel 221 and abuts against the limiting wall, the internal space of the channel is fully utilized, contributing to the miniaturization of the device's radial dimensions and making the structure more compact. The above-mentioned configuration of the elastic element 25 provides a flexible option for equipment with different spatial layouts and performance requirements, ensuring reliable reset and sealing of the spherical body 26 while optimizing water flow efficiency and structural design.

[0046] Optionally, multiple water inlet channels 221 within the water inlet head 223 are evenly arranged around the water outlet direction; and at least one water inlet channel 221 within the guide column 222 is located within the area enclosed by the multiple water inlet channels 221 within the water inlet head 223 along the water outlet direction.

[0047] In this embodiment of the application, there can be 5 water inlet channels 221, such as 4 water inlet channels 221 in the water inlet head 223 and one water inlet channel 221 in the middle of the guide column 222.

[0048] In this way, by uniformly arranging multiple inlet channels 221 within the inlet head 223 around the outlet direction, the water flowing in from the water tank 10 can be evenly distributed around the outlet channel. This helps to balance the inlet pressure around the inlet component 22, reduce vibrations that may be caused by uneven water flow, or interference with the motion of the spherical body 26, thereby improving water flow stability. Simultaneously, by placing at least one inlet channel 221 within the guide column 222 in the central area enclosed by the projection of multiple inlet channels 221 along the outlet direction within the inlet head 223, water flowing in from the center of the guide column 222 and water flowing in from the circumference of the inlet head 223 converge in the outlet channel. This combination of central and circumferential inlet methods can form a smoother and more concentrated water flow path, which is beneficial for improving inlet efficiency and may utilize the interaction of water flow to reduce the deposition of impurities in the front end area of ​​the guide column 222. This, to a certain extent, supports the reliability of the outlet docking device 20 in maintaining good working condition in water containing fine dust.

[0049] Optionally, the denture grinding apparatus also includes a pin 33 assembly 30. The pin 33 assembly 30 enables the water outlet connection device 20 to be in an advanced state, allowing water in the water tank 10 to flow out after passing through the water outlet connection device 20 and the pin 33 assembly 30.

[0050] In this way, by adding the ejector pin assembly 33 30, when the water outlet head 31 is connected to the water outlet docking device 20, the ejector pin 33 can extend into the water outlet docking device 20, pushing the spherical body 26 away from its initial position, thereby forcing the water outlet docking device 20 to change from a non-push-in state to a push-in state. This action overcomes the elastic force of the elastic element 25, opens the water outlet channel closed by the spherical body 26, and allows the water in the water tank 10 to flow smoothly out after passing through the opened water outlet channel and the guide channel 32 in the ejector pin assembly 33 30, realizing controllable water circuit conduction. When water needs to be changed or separated, simply disconnect the ejector pin assembly 33 30 from the water outlet docking device 20, and the spherical body 26 will automatically return to the sealed position under the action of elastic force, blocking the water flow. This avoids the cumbersome steps of disassembling water pipes in the traditional method, simplifies the plugging and unplugging operation of the water tank 10, improves the water change efficiency, and enhances the reliability and convenience of water circuit opening and closing through the combination of mechanical pushing and automatic reset.

[0051] Optionally, the ejector pin assembly 30 includes a water outlet head 31 and an ejector pin 33. The water outlet head 31 includes a flow guiding channel 32; the ejector pin 33 is disposed within the flow guiding channel 32 and abuts against the limiting step 34 within the flow guiding channel 32. When the water outlet head 31 is connected to the water outlet docking device 20, the ejector pin 33 extends into the water outlet docking device 20 and pushes the spherical body 26 away from its initial position, allowing water in the water tank 10 to flow out after passing through the water outlet channel and the flow guiding channel 32.

[0052] Thus, by setting up an ejector pin assembly 33 30 including an outlet head 31 and an ejector pin 33, where the outlet head 31 has a flow guide channel 32 and the ejector pin 33 is placed in the channel and abuts against the internal limiting step 34, when the outlet head 31 is connected to the water outlet docking device 20, the ejector pin 33 can be precisely constrained by the limiting step 34 and extend into the water outlet docking device 20, reliably pushing the spherical body 26 away from the initial sealing position, thereby opening the water passage. The water in the water tank 10 can flow out after passing through the connected water outlet channel and the flow guide channel 32 in the ejector pin assembly 33 30, realizing the controllable conduction of the water passage. The design of the limiting step 34 ensures that the ejector pin 33 will not undergo excessive displacement during the pushing process, avoiding sealing failure or component damage between the ejector pin assembly 33 30 and the spherical body 26 due to misalignment or excessive stroke, improving the stability of the pushing operation and the reliability of the entire water passage opening and closing operation.
