Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, and in particular to a spatial layout structure for a dental prosthesis carving machine and the dental prosthesis carving machine. Background Technology

[0002] The spatial layout of a dental prosthesis engraving machine mainly refers to the rational arrangement and coordinated operation of the equipment body, work platform, chip removal system, and auxiliary devices in physical space. Typically, the engraving machine should be placed on a stable, vibration-proof workbench, and its spindle movement path should avoid obstacles to ensure smooth operation of the three-axis or five-axis linkage system. Furthermore, to improve work efficiency and ease of operation, the engraving area and raw material supply area need to be clearly separated to facilitate seamless connection between loading, processing, and unloading. At the same time, the chip removal port and dust collection system should also be rationally arranged to avoid dust accumulation affecting accuracy or polluting the environment.

[0003] The rationality of the spatial layout has a significant impact on the processing accuracy and operating efficiency of dental prosthesis engraving machines. A good layout can not only shorten the processing path and reduce mechanical interference, but also reduce machine wear and improve long-term stability. At the same time, a convenient operating area design can reduce technician fatigue and improve processing efficiency; while a well-designed chip removal path and ventilation system help maintain the cleanliness of the processing area and prevent dust from damaging the quality of the dentures and the electronic systems.

[0004] Patent application CN114227955A discloses a dental prosthesis carving machine, such as... Figure 1 As shown, it includes: an automatic loading and unloading mechanism 100, a three-axis drive mechanism, a material rack 810, and a processing spindle 200. Its cavity is divided into two parts: a material cavity 800 and a processing cavity 700, and a partition wall 300 is set in the middle to separate the two cavities. During denture processing, the waste generated during the processing (such as zirconium oxide waste) can be isolated in the processing cavity 700. The arrangement direction of the automatic loading and unloading mechanism 100 and the z-axis drive mechanism is adapted to the arrangement direction of the material cavity 800 and the processing cavity 700.

[0005] The aforementioned dental prosthesis engraving machine aims to simplify its structure and reduce costs by using a parallel structure where the automatic loading / unloading mechanism and the Z-axis drive mechanism move in the X and Y axes, achieving miniaturization while retaining its automatic loading / unloading function. However, it is clear that this dental prosthesis engraving machine cannot meet the requirements of wet processing for liquid circulation and drainage paths. Wet processing typically requires a coolant circulation system, a spray device, and a liquid collection and drainage system, which are difficult to rationally arrange in the existing layout. Due to the fixed structure of the partition wall, the processing chamber space is limited, making it difficult to expand the installation of cooling nozzles or liquid guiding structures. Furthermore, liquid easily accumulates in the processing chamber, affecting engraving accuracy and corroding the machine body. In addition, the layout, which designs the loading / unloading mechanism and the processing chamber path to be parallel and close together, also increases the risk that coolant may splash onto automatic mechanisms, motors, and other components, leading to electrical damage. Therefore, while this spatial layout is suitable for the sealing requirements of dry processing, it cannot accommodate the higher requirements of wet processing for openness, fluid management, and coordinated operation of multiple chambers, limiting the scalability and versatility of the equipment's applicable scenarios.

[0006] This shows that the existing technology still needs to be improved and perfected. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a spatial layout structure for a dental prosthesis carving machine and a dental prosthesis carving machine, which aims to solve the problem that although the spatial layout of the existing dental prosthesis carving machine is suitable for the sealing requirements of dry processing, it cannot be compatible with the requirements of wet processing for openness, fluid management and multi-cavity coordinated operation.

[0008] The technical solution of this utility model is as follows:

[0009] A spatial layout structure for a dental prosthesis carving machine includes: a dental prosthesis processing chamber, a dust removal device, a waste liquid collection device, and a mist-like impurity discharge device. The dust removal device is located on a first side below the dental prosthesis processing chamber and is connected to the dental prosthesis processing chamber, for discharging dust generated during the dental prosthesis processing. The waste liquid collection device is located directly below the dental prosthesis processing chamber and is connected to the dental prosthesis processing chamber, for discharging waste liquid and impurities mixed in the waste liquid during the dental prosthesis processing. The mist-like impurity discharge device is located on a second side below the dental prosthesis processing chamber and is connected to the dental prosthesis processing chamber, for discharging oil mist and water mist generated during the dental prosthesis processing.

[0010] The advantages of the above solution are as follows: This utility model constructs a multi-channel discharge system with clearly defined functional zones and mutual coordination by setting dust removal devices, waste liquid collection devices, and mist impurity discharge devices in different lower areas of the denture processing cavity. This breaks through the bottleneck of traditional fixed partition wall cavity layout lacking fluid management capabilities under wet processing conditions. First, the dust removal device is located on the lower side of the processing cavity and is connected to it, which can promptly remove dust particles (such as zirconia chips) during dry processing, effectively preventing dust accumulation in the processing cavity, maintaining processing cleanliness, and protecting precision components such as the spindle and optical recognition elements, ensuring processing accuracy. Second, the waste liquid collection device is located directly below the processing cavity, which can collect and guide the cutting fluid containing debris during wet processing, preventing liquid accumulation that could cause secondary pollution and corrosion of electronic systems. It also facilitates subsequent liquid separation and treatment, improving the overall machine's environmental adaptability and service life. Third, mist impurity discharge... The device, located on the other lower side, is specifically designed to capture water mist or oil mist generated during processing due to high-speed rotation or spray rinsing, preventing it from condensing on the cavity wall or drifting into the electrical area, thus further protecting the operational stability of the drive components and sensing system. The three discharge structures work together to enable the processing cavity to have efficient powder, liquid, and gas impurity separation capabilities in both dry and wet processing modes. This satisfies the sealing requirements of dry processing while also meeting the requirements of wet processing for openness, fluid guidance and control, and coordinated cavity operation, greatly expanding the process compatibility and application scenarios of the engraving machine and truly achieving the goal of multi-functionality.

[0011] In a further preferred embodiment, the waste liquid collection device includes a waste liquid collection tank, an isolation inner shell is provided on the outside of the waste liquid collection tank, an exhaust port is provided on the isolation inner shell, and the space volume formed between the isolation inner shell and the outer shell of the dental prosthesis carving machine is greater than the cross-sectional area of ​​the exhaust port.

[0012] The effectiveness of the above solution lies in the following: By installing an inner isolation shell on the outside of the waste liquid collection tank and opening an exhaust vent on the inner isolation shell, and ensuring that the volume of the space formed between the inner isolation shell and the outer shell of the dental prosthesis engraving machine is larger than the cross-sectional area of ​​the exhaust vent, a buffer diffusion zone is structurally created in the path for guiding mist impurities. Because this space has a significantly larger volume expansion compared to the cross-sectional area of ​​the exhaust vent, when oil mist, water mist, and mixed gases generated during dental prosthesis processing enter this space through the exhaust vent, the airflow velocity rapidly decreases upon entering the large volume space, the kinetic energy of the airflow diminishes accordingly, and the local negative pressure intensity is significantly weakened. This causes the mist impurities to transform into a low-speed diffusion state within this space. This state helps suspended particles to naturally settle, condense on the space wall, or accumulate in the lower area, thereby reducing the probability of mist impurities directly entering the subsequent exhaust duct, reducing the risk of blockage and pollution in the exhaust path, and decreasing maintenance frequency. This not only improves the primary separation and collection efficiency of mist impurities but also optimizes the air quality and fluid path cleanliness of the dental prosthesis engraving machine in a wet processing environment, thus enhancing the environmental adaptability and overall stability of the equipment.

[0013] In a further preferred embodiment, the collection box is disposed on the outside of the isolation inner shell, and one end of it abuts against the inner wall of the denture carving machine housing. The denture carving machine housing is provided with exhaust array holes corresponding to the position of the collection box.

[0014] The advantages of the above solution are as follows: During processing, mist-like impurities enter the collection box through the exhaust vent. After a certain period of diffusion and settling, the impurities are effectively captured and isolated within the collection box. Because the collection box has a certain volume, the residence time of impurities within it is increased, thereby improving particle settling efficiency and reducing the possibility of mist-like impurities being discharged with the airflow. In this case, the exhaust array holes, serving as the final discharge channel, ensure smoother and more uniform exhaust gas flow through a uniformly distributed array design, avoiding the problem of excessively high local negative pressure caused by concentrated discharge from a single exhaust vent, thus effectively reducing the risk of blockage. This setup not only improves exhaust gas treatment efficiency but also enhances system stability, reducing maintenance frequency and the probability of exhaust system failure.

[0015] In a further preferred embodiment, an air inlet for connecting to the outside is provided at the upper right or upper left corner of the denture processing cavity.

[0016] The advantages of the above solution are as follows: By setting an air inlet in the upper right or upper left corner of the denture processing cavity to connect with the outside, a directional fresh airflow can be introduced into the processing cavity. Since the air inlet is located in the upper area of ​​the processing cavity, the airflow process will cause the air to flow downwards, thus creating a downward airflow within the denture processing cavity. This directs pollutants such as dust and mist impurities accompanying the processing downwards to the areas where dust removal devices, waste liquid collection devices, or mist impurity discharge devices are located, thereby improving the collection efficiency of impurities. Simultaneously, this structure allows the fresh airflow to dilute the pollutant gases as it enters the processing cavity, which helps reduce the concentration of pollutants, slows their diffusion rate, and improves the air quality inside the processing cavity. Because the air inlet is directly connected to the outside, it can guide outside air in without relying on an active fan device, thus improving ventilation efficiency while maintaining the overall structural compactness.

[0017] In a further preferred embodiment, an air inlet duct is provided between the inner side of the outer shell of the dental prosthesis carving machine and the air inlet, and the side of the air inlet duct closest to the outer shell of the dental prosthesis carving machine is a compression pipe.

[0018] The above solution achieves the following effects: By installing an air inlet duct between the inner side of the denture engraving machine's outer shell and the air inlet, an independent air inlet channel can be constructed within the equipment structure. This prevents external airflow from directly entering the processing chamber, thus avoiding turbulence and improving the orderliness and directionality of the internal airflow organization. Furthermore, by installing a compression section near the outer shell of the air inlet duct and narrowing its cross-sectional area, a "Venturi effect" is created during air intake. This significantly increases the airflow velocity and relatively reduces the pressure, thereby enhancing the overall airflow's kinetic energy. This enhanced airflow kinetic energy generates a stronger directional driving force before entering the denture processing chamber, helping to propel contaminants (such as dust, oil mist, and water mist) towards the dust removal or discharge device at the bottom of the processing chamber, thereby improving the migration and collection efficiency of impurities. In addition, the compression section's structural design also provides airflow throttling and stabilization, helping to maintain a relatively stable airflow rate even under unstable system negative pressure or fluctuating air source conditions. This ensures the denture engraving machine's consistent operation and environmental adaptability under different working conditions, thereby enhancing the stability of the overall gas circulation system and the equipment's reliable operation.

[0019] In a further preferred embodiment, the first end of the compression tube is attached to the housing of the dental prosthesis carving machine, and a contraction port is provided in the middle region of the first end. The contraction port gradually narrows from the first end to the second end, forming a channel structure that gradually narrows along the airflow direction.

[0020] The advantages of the above solution are as follows: By setting a gradually narrowing inclined contraction port at the first end of the compression pipe, the airflow can be guided to accelerate in the initial stage of entering the air inlet duct and gradually form a stable jet flow. Because the contraction port gradually narrows along the airflow direction, its cross-sectional area decreases, causing a continuous "acceleration-pressure reduction" process after the airflow enters the contraction port. This change conforms to the fluid dynamics principle of gas flow, namely the Venturi effect. With the help of this effect, the airflow velocity increases while the pressure decreases, thus forming an effective low-pressure zone between the compression pipe and the air inlet, which helps to enhance the driving force for the intake of external gas and improve the overall air intake efficiency. Furthermore, the accelerated airflow has stronger momentum before entering the processing chamber, which can effectively drive dispersed or suspended impurities in the chamber towards the dust removal device, improving the migration efficiency of dust, oil mist, or water mist and reducing their retention inside the equipment. At the same time, this structure also has the effect of preventing backflow and stabilizing the airflow direction, enhancing the airflow control capability of the equipment in complex environments, thereby improving the gas regulation capability and operational stability of the dental prosthesis engraving machine under wet processing or high dust load conditions.

[0021] In a further preferred embodiment, the air inlet duct includes a first duct and a second duct, the compression section and the air inlet are disposed in the first duct, and the second duct abuts against the air inlet and is sleeved on the inner edge of the second end of the first duct.

[0022] The advantages of the above solution are as follows: By dividing the air intake duct into two sections, a first duct and a second duct, and placing the compression section and air inlet within the first duct, the functions of the airflow acceleration section (compression section) and the diversion section (second duct) are clearly distinguished, thereby improving the modularity and functional clarity of the entire air intake system. The second duct, with one end abutting the air inlet and fitted inside the second end of the first duct, forms a detachable or sliding fit structure. This not only facilitates installation and subsequent maintenance but also allows for quick replacement or flexible adjustment of different duct sections as needed, enhancing the adaptability and upgrade potential of the air intake system. Furthermore, since the second duct is fitted inside the first duct, an annular gap or sealing area is formed at the fitting point. This structure acts as a buffer during airflow, reducing the impact of the high-velocity airflow at the end of the first duct and preventing interference or erosion of the air inlet structure, thus improving the overall stability and service life of the air intake system. Furthermore, this dual-section structural design also facilitates segmented control of the pipe wall material and structure. For example, the first pipe can be made with a smooth or tapered inner wall that is conducive to compressive flow, while the second pipe can be made with a material and structure that is conducive to deceleration, diffusion, or filtration and guidance. This improves the airflow efficiency and internal airflow quality of the entire dental prosthesis carving machine, effectively enhancing its environmental control capabilities and the reliability of system operation.

[0023] In a further preferred embodiment, the diameter of the contraction opening is smaller than the diameter of the air inlet, and a cylindrical central hole is provided in the middle of the second pipe, the diameter of which is equal to the diameter of the air inlet.

[0024] The above solution achieves the following effects: By setting the diameter of the contraction port to be smaller than that of the air inlet, a compression section is formed inside the first duct. This causes the outside air to experience a contraction effect upon entering the contraction port, increasing airflow velocity and decreasing pressure, thereby enhancing the airflow driving force and improving the ventilation efficiency inside the dental prosthesis carving machine. Simultaneously, the cylindrical central hole in the middle of the second duct, with a diameter equal to that of the air inlet, acts as an expansion buffer zone for the airflow. After the high-speed airflow accelerates through the contraction port into the second duct, the central hole, with the same diameter as the air inlet, redistributes the airflow path, reducing turbulence and impact, and creating a near-laminar flow state, which is beneficial for the stable guidance of airflow into the dental prosthesis processing cavity. This structure, through the combination of "acceleration at the front and diffusion and stabilization at the rear," not only improves the overall ventilation system's airflow efficiency and airflow uniformity but also reduces the risk of disturbance and wear caused by high-speed airflow directly impacting the internal components of the dental prosthesis processing cavity.

[0025] In a further preferred embodiment, the left and right housings of the dental prosthesis carving machine are both of an integrated structure. The front housing includes a front upper housing, a front middle housing, and a front lower housing. The control panel is located on the front upper housing. The front middle housing is used to seal the dental prosthesis processing cavity. The front lower housing covers the waste liquid collection area. The rear housing includes a rear upper housing and a rear lower housing. The rear upper housing covers the area where the three-axis transfer mechanism is located. The rear lower housing covers the A-axis setting area and the electrical setting area.

[0026] The above solution achieves the following results: by designing the left and right shells of the dental prosthesis engraving machine as a single integrated structure, it significantly reduces the splicing steps in the assembly process, improves the overall structural strength and assembly precision of the machine, thereby enhancing the overall stability and shock resistance of the machine body and improving the precision and reliability of dental prosthesis processing. The front shell is functionally divided into a front upper shell, a front middle shell, and a front lower shell, with the control panel located on the front upper shell. This allows the user interface and control area to be concentrated on the upper front of the machine body, conforming to ergonomic design and improving ease of use. The front middle shell seals the dental prosthesis processing cavity, effectively preventing dust, mist impurities, or waste liquid from overflowing during processing, ensuring a clean internal environment. The front lower shell covers the waste liquid collection area, facilitating later cleaning and maintenance, and also serves as a shield against contamination. The rear shell is functionally divided into a rear upper shell and a rear lower shell. The rear upper shell covers the area where the three-axis transfer mechanism is located, helping to reduce dust intrusion and external impact, and improving the operational stability of the transmission system. The rear lower shell provides independent protection for the A-axis setting area and the electrical setting area, helping to improve the safety and operational reliability of key control components. Overall, through the rational division of functional modules and the integrated design of the shell, this structure not only optimizes the structural layout and processing environment of the dental prosthesis carving machine, but also improves the overall performance of the machine in terms of user experience, sealing, safety and stability.

[0027] A dental prosthesis carving machine includes the spatial layout structure for a dental prosthesis carving machine as described above. Since the dental prosthesis carving machine incorporates all the technical features of the aforementioned spatial layout structure for a dental prosthesis carving machine, it also possesses all the technical effects of the aforementioned spatial layout structure for a dental prosthesis carving machine, and will not be elaborated further.

[0028] Compared with existing technologies, the spatial layout structure for a dental prosthesis engraving machine provided by this utility model includes a dental prosthesis processing chamber, a dust removal device, a waste liquid collection device, and a mist impurity discharge device. The dust removal device is located on one side below the processing chamber to promptly remove dust, such as zirconia chips, during dry processing, preventing accumulation and contamination, improving processing accuracy, and protecting the spindle and optical components. The waste liquid collection device is located directly below the processing chamber to collect cutting fluid containing debris during wet processing, preventing liquid accumulation, reducing corrosion, and facilitating subsequent processing. The mist impurity discharge device is located on the other side to discharge water mist or oil mist, preventing condensation or diffusion to electrical areas and protecting sensors. This layout achieves efficient separation of powder, liquid, and gas impurities by setting dedicated discharge channels in different areas, solving the problem of lack of fluid guidance control in traditional structures during wet processing, improving the cleanliness of the processing environment, the stability of equipment operation, and process compatibility, and achieving the goal of dual-use (dry and wet) and multi-functionality.

[0035] This utility model provides a spatial layout structure for a dental prosthesis carving machine and a dental prosthesis carving machine. To make the purpose, technical solution and effect of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and examples.

[0036] This utility model provides a spatial layout structure for a dental prosthesis carving machine, such as Figure 2 As shown, the spatial layout structure includes: a denture processing chamber 100, a dust removal device ( Figure 2 The symbol 210 indicates the dust outlet of the dust removal device and the waste liquid collection device. Figure 2 The marked 410 refers to the waste liquid collection tank of the waste liquid collection device and the mist impurity discharge device. Figure 2 The number 310 indicates the exhaust port of the mist impurity discharge device.

[0037] The denture processing chamber 100 is located in the central area of ​​the denture carving machine and is used for cutting, carving, and other processing operations of dentures. During the denture processing, various waste substances such as dust, cutting fluid, oil mist, and water mist are usually generated. Therefore, this embodiment achieves multi-channel impurity discharge function by setting up multiple clearly defined discharge structures.

[0038] The dust removal device is located on the lower first side (e.g., the lower right or lower left side) of the denture processing cavity 100 and forms an airflow communication with the denture processing cavity 100. It is used to promptly remove dust particles (such as zirconia dust) generated during the processing in dry processing mode, prevent dust from accumulating in the cavity, thereby maintaining the cleanliness of the processing area, avoiding dust adsorption on the surface of the spindle, optical components or other precision mechanisms, and ensuring processing accuracy and equipment service life.

[0039] The waste liquid collection device is located directly below the denture processing cavity 100 and is connected to the denture processing cavity 100 through a guide structure. It is used to collect the cutting fluid and solid debris carried in it during the wet processing and discharge them in a unified manner to prevent the liquid from accumulating in the cavity and avoid problems such as structural corrosion and electrical short circuits. At the same time, it facilitates the subsequent separation, treatment and reuse of waste liquid.

[0040] The mist-like impurity discharge device is located on the second side below the denture processing cavity 100 (the side opposite to the first side) and is connected to the denture processing cavity 100. It is used to collect oil mist and water mist formed during the processing due to spraying, rotation and other operations, so as to prevent water vapor or oil vapor from condensing on the inner wall of the cavity or spreading to the electrical or sensing area, so as to ensure the dryness of the internal environment of the engraving machine and the safe operation of key components.

[0041] This utility model creates dedicated discharge channels for dust, waste liquid, and mist impurities by setting three different discharge devices in different lower areas of the denture processing cavity 100. This achieves a reasonable division of labor and coordinated operation in the spatial layout, significantly improving the equipment's process adaptability and environmental management capabilities in both dry and wet processing modes. It has good practicality and promotional value.

[0042] In practical implementation, a drain port 110 is provided at the center of the lower end of the denture processing cavity 100 (e.g., Figure 3 As shown), and is connected to the waste liquid collection device and the mist impurity discharge device through the drain port 110, that is, preferably the waste liquid collection device and the mist impurity discharge device share the same chip discharge port; a dust removal port 120 is provided on one side of the lower end (as shown). Figure 3As shown in the figure, it is connected to the dust removal device through the dust removal port 120. With the above configuration, on the one hand, the bottom structure layout is effectively simplified, and the number of discharge ports is reduced while ensuring discharge efficiency. This is conducive to compressing the overall size of the equipment and improving the sealing performance of the shell. On the other hand, since the drain port is located at the lowest point of the cavity, the waste liquid and condensed water mist and oil mist can be naturally gathered to the discharge port by gravity, which improves the discharge smoothness and avoids liquid residue in the cavity. At the same time, setting the dust removal port on one side and independently guiding the dust discharge helps to prevent the blockage problem caused by the mixing of dry dust and wet waste liquid. This further enhances the non-interference and operational stability of the multi-state impurity discharge process, thereby achieving an integrated impurity management effect that is compatible with dry and wet processing, compact and efficient.

[0043] Since the specific structures of the dust removal device, waste liquid collection device, and mist impurity discharge device are not the main inventive points of this utility model, and mature existing technologies already exist, this utility model will not elaborate further. Specifically, the dust removal device can adopt a structure with a centrifugal fan combined with a dust collection filter cartridge or a HEPA high-efficiency filter module to achieve efficient extraction and filtration of dust particles; the waste liquid collection device can include a structure with an inlet, a guide channel, and a detachable storage box, guiding the waste liquid to be collected centrally through gravity flow and guiding design; the mist impurity discharge device can adopt a structure with a mist inlet, a guide fan, and a condensation separation component, effectively discharging oil mist or water mist through airflow guidance and condensation capture. The above devices are all known mature technologies in this field, and related products and implementation solutions have been widely used in CNC machining equipment, industrial cleaning equipment, and medical automation equipment. Those skilled in the art can implement them without creative effort.

[0044] In a further preferred embodiment of this utility model, the waste liquid collection device includes a waste liquid collection tank 310 (e.g., Figure 2 As shown), the waste fluid collection tank 310 is used to contain the cutting fluid and its impurities discharged from the denture processing cavity 100. It is preferably made of corrosion-resistant plastic or stainless steel, and a drain valve or quick-release interface can be installed at the bottom for easy cleaning and replacement. To prevent water vapor or odor generated by waste fluid evaporation from spreading into the internal space of the machine and affecting the working stability of electrical components, an insulating inner shell 610 (such as...) is provided on the outside of the waste fluid collection tank 310. Figure 4As shown, the inner isolation shell 610 and the waste liquid collection tank 310 form a semi-enclosed structure. An exhaust port is provided on the inner isolation shell 610, which is used to connect to an exhaust fan or condenser exhaust module installed inside the inner isolation shell 610, thereby forming an effective ventilation path. Furthermore, to ensure stable flow of water vapor generated by the waste liquid tank, the volume of the space between the inner isolation shell 610 and the outer shell of the dental prosthesis carving machine is set larger than the cross-sectional area of ​​the exhaust port. This design helps to form a buffer air chamber, stabilizing the airflow path, and also prevents waste liquid from splashing or flowing back due to sudden pressure changes during exhaust.

[0045] Furthermore, a collection box 620 (such as...) can also be provided on the outside of the inner isolation shell 610. Figure 4 As shown), the collection box 620 is preferably a rectangular structure with open ends. One end abuts against the inner wall of the dental prosthesis carving machine housing to receive condensed water droplets, oil mist particles, or condensate on the wall of the inner shell 610, thereby achieving secondary protection and centralized collection.

[0046] To improve the efficiency of rapid internal gas exchange, multiple exhaust array holes can be opened on the outer shell of the dental prosthesis carving machine at the corresponding positions of the collection box 620. The array holes are arranged along the height or width of the outer shell to form an array distribution, so as to form a low-pressure zone to guide the airflow direction and further improve the extraction efficiency and the overall heat exchange performance of the machine.

[0047] To improve airflow in the denture processing cavity 100, an air inlet can be provided at the upper right or upper left corner of the cavity to introduce clean air or ambient air, achieving pressure balance and fresh air replacement within the processing area. To further improve airflow efficiency and control the intake speed, an air inlet duct 800 can also be installed between the inner side of the denture engraving machine's casing and the air inlet. Figure 5 and Figure 6 As shown, the air inlet duct 800 may be provided with a compression pipe section 821 on the side near the housing of the dental prosthesis carving machine, such as... Figure 5 As shown, the compression tube section 821 has an arc-shaped or conical shrinkage structure, and its outer shell can be made of flexible rubber or polyurethane material to facilitate assembly and sealing.

[0048] Preferably, the first end of the compression tube 821 is fitted to the housing of the dental prosthesis carving machine to ensure sealing and guidance during air introduction, and a contraction port 823 is provided in the middle region of its first end, such as... Figure 6 As shown, the contraction port 823 gradually narrows and slopes from the first end to the second end. Figure 6 The inclined surface is marked as 822, which means that the channel structure gradually narrows in the direction of airflow, thereby achieving airflow convergence and acceleration in advance before guiding the airflow into the processing chamber, so as to improve the internal vortex disturbance and the carrying capacity of fine particles.

[0049] like Figure 5 and Figure 6 As shown, the air inlet duct 800 can be composed of a first duct 820 and a second duct 810. The compression section 821 and the air inlet are together disposed on the structure of the first duct 820, while the second duct 810 is used to connect to the air inlet and is sleeved on the inner edge of the second end of the first duct 820 to achieve modular connection. This structural design facilitates later maintenance and component replacement. In further optimization, the diameter of the contraction port 823 is smaller than the diameter of the air inlet, forming a compression and air guiding structure. A cylindrical central hole is opened in the middle of the second duct 810, and the diameter of the cylindrical central hole is the same as the diameter of the air inlet. This design can ensure the stable introduction of central airflow while maintaining the edge vortex and air guiding symmetry, further improving the overall ventilation efficiency and pollutant dispersion capability.

[0050] In practical implementation, the overall shell structure of the dental prosthesis carving machine adopts a symmetrical integrated layout to improve the overall strength and processing stability of the machine body. The left and right shells are connected to the central frame through multi-point snap-fit ​​and screw-in structures, ensuring assembly accuracy while also facilitating maintenance. Each shell adopts an integrated molding design, preferably using engineering plastics (such as ABS+PC alloy) or lightweight metal materials (such as aluminum-magnesium alloy) with good flame retardancy and corrosion resistance for injection molding or die casting. The surface of the shell can be treated with sandblasting and anodizing or coating processes to improve wear resistance and stain resistance.

[0051] The front shell is composed of a front upper shell, a front middle shell, and a front lower shell, wherein:

[0052] The front upper shell is mainly used to accommodate and fix the control panel. Its structure is embedded with several cable management channels and interface reserved holes for connecting cables. The control panel can be a capacitive touch screen structure or a membrane keypad. The surface of the front upper shell is provided with reinforcing ribs to improve the rigidity of the overall panel area and prevent warping or deformation during operation.

[0053] The front middle shell is located below the front upper shell, forming a sealed compartment space around the denture processing cavity 100. Its inner surface can be covered with shock-absorbing rubber pads or sound-absorbing materials to reduce dust and noise leakage during processing. The front middle shell is equipped with a removable observation window or opening and closing door structure, which makes it convenient for users to check the internal processing status or perform simple maintenance.

[0054] The lower front cover fits over the waste liquid collection area at the bottom of the unit, covering and protecting the waste liquid collection tank and isolation structure. The bottom of the lower front cover may be equipped with quick-release buckles or a sliding rail structure for easy periodic disassembly and cleaning of the waste liquid device. The inner wall may be equipped with a guide slope to guide residual liquid to the drain port.

[0055] The rear shell portion includes an upper rear shell and a lower rear shell, structurally designed to fit and correspond with the front shell, forming a closed, integral outer shell. Specifically, it includes:

[0056] The rear upper shell is used to cover the three-axis transfer mechanism area inside the engraving machine. It has reinforced support ribs inside to ensure that the rear shell will not vibrate or crack due to load impact during operation. In addition, the top of the rear upper shell can be reserved for heat dissipation hole array or cooling fan mounting position to assist in the heat dissipation of the main drive module.

[0057] The rear lower housing primarily covers the A-axis (rotary axis, used to drive the processing base and the raw materials on it) and electrical components of the dental prosthesis processing machine. The electrical components include the main control circuit board, power module, fan driver, and other components. The rear lower housing may have a partitioned compartment structure to physically isolate the high-voltage and low-voltage areas, preventing signal interference or fault propagation. For ease of heat dissipation and maintenance, the rear lower housing may also be equipped with a side-mounted movable cover, which can be quickly opened using magnetic or sliding latches.

[0058] The above structural layout makes the overall shell of the dental prosthesis carving machine clearly divided, which facilitates modular design and zonal maintenance, and improves the overall structural stability, sealing performance and user operation convenience.
