Description

Technical Field

[0001] The utility model relates to the technical field of denture processing, in particular to a wax boiling and wax flushing integrated machine with multiple working modes. Background Art

[0002] The production process of dentures includes: impression making, model making, wax model making, embedding, wax boiling, rinsing, casting, demoulding, correction and polishing, assembly and debugging, among which (1) impression making refers to making a model of the teeth by taking an impression of the patient's mouth; (2) model making refers to pouring the impression into plaster to make a hard plaster model; (3) wax model making refers to making a wax model on the plaster model to simulate the shape and structure of the future denture; (4) embedding refers to embedding the wax model and the plaster model in the embedding material to form an overall structure; (5) wax boiling refers to removing the embedded body by heating the wax. Wax pattern, leaving the original position of the wax pattern for subsequent casting; (6) Waxing refers to using hot water or steam to clean the plaster model to remove residual wax and embedding material; (7) Casting refers to injecting metal or ceramic material into the embedding body to replace the original wax pattern position; (8) Demolding refers to removing the embedding material after cooling to obtain a preliminary denture model; (9) Trimming and polishing refers to grinding, trimming and polishing the cast denture to achieve the desired shape and finish; (10) Assembly and debugging refers to installing the denture in the patient's mouth and adjusting and debugging it to ensure comfort and normal function.

[0003] Boiling wax and flushing wax play an extremely important role in the above-mentioned denture processing process. If the wax boiling and flushing effects are not good, a lot of wax liquid will remain in the gypsum model, resulting in the casting material in the molten state during subsequent casting being unable to fill the internal cavity of the gypsum model as expected, causing the preliminary denture model obtained by casting to be incomplete. Therefore, ensuring the wax boiling and flushing effects is extremely important for the yield rate of dentures.

[0004] The utility model patent with authorization announcement number CN213406371U discloses a fully automatic wax washing machine. Figure 1 As shown, it includes: a frame frame 1 and a circuit board 2, and a wax boiling tank 11 for boiling and melting the denture glue holder in the mold box 10 to achieve wax removal and a wax flushing tank 12 for cleaning and removing the wax from the denture glue holder in the mold box 10 after wax removal is installed in the upper middle part of the frame frame 1. The wax boiling tank 11 and the wax flushing tank 12 are arranged side by side and distributed in a stepped manner, and the wax boiling tank 11 and the wax flushing tank 12 work independently; a wax boiling drain pipe 110 is connected to the bottom of the wax boiling tank 11 to facilitate the discharge of waste water in the tank body, and a wax removal drain pipe 120 is connected to the bottom of the wax flushing tank 12 to facilitate the discharge of waste water in the tank body, and a drain valve 13 for controlling the on-off of each pipeline is respectively provided on the wax boiling drain pipe 110 and the wax removal drain pipe 120.

[0005] The fully automatic wax washing machine disclosed in CN213406371U is designed to achieve safe and automatic wax boiling and wax removal through independently working wax boiling tanks and wax flushing tanks, so as to solve the tedious operation of traditional manual water boiling, wax removal and wax opening. However, due to individual differences among patients (the oral structure, occlusion relationship and tooth morphology of each patient are different, and the wax model needs to be customized according to these individual characteristics, resulting in differences in the shape, thickness and detail design of the wax model), as well as the choice of opening the wax box or not opening the wax box (when dealing with complex or detailed wax models, opening the wax box can make wax flushing more direct and efficient; in some cases, such as when the wax model is relatively simple or there are many details that need to be protected, keeping the wax box closed can prevent excessive impact force from damaging the model surface), the wax flushing effect of the single boiling water jet structure adopted by the above-mentioned wax washing machine is relatively poor.

[0006] The utility model patent with authorization announcement number CN213435964U discloses an injection molding wax flushing machine, such as Figure 2 As shown, it comprises a wax stripping machine body 1 with a wax stripping chamber 2. Two spray pipes 3 are disposed within the wax stripping chamber 2. The two spray pipes 3 are parallel to each other and located on either side of the upper portion of the wax stripping chamber 2. The spray pipes 3 are equipped with multiple atomizing nozzles to spray and remove wax from the dentures in the wax stripping chamber 2. To distinguish the spray pipes 3 from conventional fixed structures, the ends of the spray pipes 3 are rotatably connected through the side walls 201 of the wax stripping chamber 2. This rotatable connection is achieved by adding bearings. A spiral limit groove 301 is processed at one end of the spray pipe 3, and a limit pin 202 extending into the spiral limit groove 301 is provided at the rotation connection (perforation) between the side wall 201 of the wax flushing chamber 2 close to the spiral limit groove 301 and the spray pipe 3. The end of the limit pin 202 is a smooth spherical shape, and the end of the limit pin 202 slides with the spiral limit groove 301. When the entire spray pipe 3 moves axially, that is, moves relative to the side wall 201, under the interaction between the limit pin 202 and the spiral limit groove 301, the entire spray pipe 3 must be accompanied by an axial rotation movement at a certain angle, thereby achieving the purpose of moving and swinging the spray pipe 3 along its axial direction.

[0007] The injection wax stripping machine disclosed in CN213435964U merely changes the traditional fixed spray pipe to a movable one. By activating the drive mechanism, the two spray pipes are simultaneously driven to move in opposite directions and rotate at a certain angle, thereby expanding the spraying surface of the atomizing nozzles on the spray pipes. However, the injection wax stripping machine also has the problem of using a single boiling water spray mechanism, resulting in poor wax stripping effect due to individual patient differences and the choice of whether to open the box or not.

[0008] Therefore, the prior art needs to be improved and perfected. Utility Model Content

[0009] In view of the above-mentioned deficiencies in the existing technology, the purpose of the present invention is to provide a wax boiling and wax flushing machine with multiple working modes, aiming to solve the problem that the existing wax flushing machine adopts a single boiling water spray structure, resulting in poor wax flushing effect due to individual differences among patients and the choice of opening the box or not.

[0010] The technical solution of the utility model is as follows:

[0011] A wax boiling and wax flushing machine with multiple working modes includes a wax boiling tank, a heating mechanism and a hot water spraying mechanism. It also includes: a steam pot, a water vapor mixing spraying mechanism and a steam spraying mechanism. The steam pot is used to generate water vapor. The water vapor mixing spraying mechanism is used to draw hot water and water vapor from the steam pot to spray a water vapor mixture for wax flushing. The steam spraying mechanism is used to draw water vapor from the steam pot to spray water vapor for wax flushing.

[0012] The above scheme has the following advantages: the wax boiling and wax flushing machine disclosed in the utility model provides four different operating modes: boiling wax, hot water wax flushing, water-vapor mixed wax flushing, and steam wax flushing. Boiling wax effectively heats and melts the wax model, enhancing its fluidity and performing preliminary wax removal. Hot water wax flushing, taking advantage of the fact that hot water has a greater impact force than boiling wax but is still relatively gentle, can directly flush the wax model cavity exposed by opening the box. Water-vapor mixed wax flushing, taking advantage of the rapid expansion of gas to generate a stronger impact force, mixes water vapor in hot water to generate a greater impact force, and injects the water-vapor mixture into the embedded model, effectively removing wax without opening the box to protect the fragile parts of the plaster model. Steam wax flushing can directly act on the surface of the removed plaster model. Under controlled pressure, steam can penetrate into tiny crevices to perform a final cleaning of the plaster model before casting, improving the surface cleanliness of the cleaned plaster model and thereby improving the quality of the cast denture. Furthermore, the hot water spray mechanism, water-vapor mixed spray mechanism, and steam spray mechanism can draw the required water and steam from the steam boiler, effectively integrating the required functions of each mechanism to achieve efficient and convenient operation. Through this modular design, users can flexibly choose the most suitable working mode according to the different wax model characteristics and cleaning needs to ensure the maximum wax removal effect. In addition, the transition between each working mode is smooth, which greatly shortens the operation time and improves production efficiency. It can be seen that the multiple working modes of the utility model not only adapt to the individual differences of different patients and meet the cleaning needs of various complex wax models, but also effectively reduce the risk of model damage caused by improper operation; while improving the cleaning effect, it optimizes the user experience, simplifies the workflow, and makes the denture production process more efficient and accurate, thereby improving the quality of the final product.

[0013] In a further preferred embodiment, the wax boiling and wax flushing machine also includes: a switching switch and a first spray pipe, the water vapor mixing spray mechanism and the steam spray mechanism share the first spray pipe, and the switching switch is used to control the first spray pipe to switch between spraying water vapor mixture and water vapor.

[0014] The effect of the above solution is that by sharing the same injection pipe with the water vapor mixing injection mechanism and the steam injection mechanism, the complexity and manufacturing cost of the equipment can be effectively reduced, while the convenience of operation is improved. The design of the toggle switch allows the user to flexibly switch between spraying water vapor mixture and water vapor, so that the equipment can respond quickly to different cleaning needs. Overall, the design of the shared injection pipe not only reduces the number of equipment components and reduces the failure rate, but also improves the stability and reliability of the overall system, ensures the rapid conversion between water vapor mixing and steam injection, and meets the individual cleaning needs of different patients without affecting the cleaning effect, thereby further improving the quality and efficiency of denture production.

[0015] In a further preferred embodiment, the wax boiling and wax flushing machine further includes a foot switch, and the foot switch is used to control the first spray pipe.

[0016] The above solution is effective in that the user can start or stop the spraying of the first spray tube at any time when cleaning is required by controlling the spraying of the first spray tube through a foot switch, thus avoiding the risk of manual operation errors. During the cleaning process, the instant responsiveness of the foot switch allows the user to more flexibly adjust the spraying time and even the intensity, ensuring a more precise spraying of the water vapor mixture or steam to meet the cleaning needs of different wax models. In addition, the foot switch design enhances the operability of the device, especially when handling complex wax models or small plaster models. It can effectively avoid accidental impacts on the model surface, protect its details from damage, and improve the quality of the produced dentures.

[0017] In a further preferred embodiment, the hot water spraying mechanism includes: a second spraying pipe and a gear regulating valve, wherein the second spraying pipe is used to spray hot water drawn from the steam boiler, and the gear regulating valve is used to control the speed and flow of the water sprayed by the second spraying pipe.

[0018] The benefits of this solution are as follows: the design of the hot water spray mechanism, through the introduction of a second spray pipe and a gear-adjusting valve, enables adjustable water flow rate and flow rate, thereby enhancing cleaning flexibility and precision. Specifically, users can freely adjust the spray flow rate based on the shape and complexity of different wax models, ensuring the appropriate intensity during cleaning. This is particularly important when working with intricately detailed or fragile wax models. By optimizing the water flow rate, residual wax can be effectively removed while avoiding excessive impact on the model surface, reducing potential damage. Furthermore, the gear-adjusting valve makes the device more adaptable, meeting diverse cleaning needs, from quick rinses of simple wax models to deep cleanings of intricate details. Furthermore, the water sprayed by the second spray pipe originates from the wax boiling tank, which serves not only as the wax boiling and melting chamber but also as a hot water storage chamber for the hot water spray mechanism and the water-vapor mixing spray mechanism. This improves the integration of the various functions of the wax boiling and flushing machine, reduces its component count, and reduces its size, production costs, and floor space.

[0019] In a further preferred embodiment, the wax boiling and wax flushing machine also includes: a steam pot control switch and a steam pot status indicator light. The steam pot control switch is used to control the start and shut down of the steam pot. The steam pot status indicator light is arranged on one side of the steam pot control switch to indicate whether the steam pot is currently in the on state.

[0020] The effect of the above solution is that the design of the steam pot control switch and the switch indicator light improves the operational safety and user-friendliness of the wax boiling and wax flushing machine. Through clear switch control, users can easily start or turn off the steam pot, thereby effectively managing the generation and use of steam and preventing accidents caused by improper operation. The setting of the indicator light provides users with real-time feedback, ensuring that they can clearly understand the opening status of the steam pot during the cleaning process, avoiding incomplete cleaning or damage to the model due to misoperation. In particular, with the setting of the foot switch, users can more flexibly adjust the timing of steam use and seamlessly switch with other cleaning modes, thereby ensuring the best cleaning effect when dealing with complex wax models, further improving the quality and efficiency of denture production.

[0021] In a further preferred embodiment, the wax boiling and wax flushing machine further comprises: a water level sensor, which is used to detect the water level in the steam pot to prevent the steam pot from drying out due to lack of water.

[0022] The effect of the above solution is that the introduction of the water level sensor significantly improves the safety and reliability of the wax boiling and wax flushing machine. By monitoring the water level in the steam pot in real time, the sensor can accurately determine whether there is enough water. Once the water level is lower than the safety threshold, the system will automatically cut off the heating source to prevent the steam pot from drying out due to lack of water. This function not only effectively protects the equipment itself and extends its service life, but also reduces the safety hazards caused by equipment failure. In addition, the water level sensor ensures a continuous supply of steam (combined with a water supply device, it can achieve timely water supply when the water level reaches the preset threshold to ensure a continuous supply of steam), so that the steam pot can maintain a stable steam output while working efficiently, thereby optimizing the entire cleaning process. Users do not need to worry about overheating of the steam pot during use, and can focus more on the cleaning operation, which improves work efficiency and user experience.

[0023] In a further preferred embodiment, the wax boiling and wax flushing machine also includes: a wax boiling tank control switch and a wax boiling tank status indicator light. The wax boiling tank control switch is used to control the start and shut down of the wax boiling tank. The wax boiling tank status indicator light is arranged on one side of the wax boiling tank control switch to indicate whether the wax boiling tank is currently in the open state.

[0024] The above solution achieves this by enhancing the ease and safety of operation of the wax-boiling and wax-washing machine with a control switch and status indicator. Users can directly activate and deactivate the wax-boiling tank with a simple on / off switch, enabling flexible wax model processing. This allows users to quickly adjust the machine's status at different stages of operation, preventing the wax model from reaching the desired temperature and affecting wax removal. Furthermore, the status indicator provides real-time feedback, ensuring users clearly understand the operating status of the wax-boiling tank and preventing equipment damage or safety hazards caused by misoperation.

[0025] In a further preferred embodiment, the wax boiling and wax flushing machine further includes: a wax flushing table, which is arranged above the side of the wax boiling tank and is connected to the wax boiling tank so that the water after wax flushing flows back to the wax boiling tank.

[0026] The effect of the above solution is that by placing the wax flushing station above and to the side of the wax boiling tank and connecting it, the waste water generated during the flushing process can flow directly back to the wax boiling tank, reducing the waste of water resources and achieving recycling, so that the equipment always maintains the optimal water level and temperature during the dewaxing operation (water drawn from the water source requires a certain amount of heating time, and by drawing hot water from the steam boiler, the hot water after wax flushing flows back to the wax boiling tank, forming a water cycle, reducing the time required for water heating), thereby improving the cleaning effect. At the same time, the external water source required in the cleaning process is reduced, the operating cost is reduced, and it is particularly suitable for large-scale denture production. In addition, the connection design between the wax flushing station and the wax boiling tank simplifies the overall structure of the equipment, making operation more convenient, and users can easily perform cleaning and maintenance, which improves work efficiency.

[0027] In a further preferred embodiment, a through groove is provided at the bottom of the wax washing table, and a return plate is provided directly below, a return gap is reserved between the return plate and the bottom end of the wax washing table, and the wax washing table is connected to the wax boiling tank through the through groove and the return gap.

[0028] The effect of the above solution is that the presence of the through-groove allows the wastewater generated during the wax flushing process to flow smoothly to the return plate and then efficiently return to the wax boiling tank through the reserved return gap. This not only prevents the accumulation of wastewater on the flushing table, reducing the complexity of cleaning and maintenance, but also ensures that the temperature and composition of the flushing water can be recovered in a timely manner, maintaining the efficient operation of the system. If wastewater accumulates on the flushing table, the residual wax and embedding material in the wastewater are likely to re-adhere to the plaster model. The provision of the through-groove effectively avoids this problem. Combined with the provision of the return plate and return gap, while ensuring the wax flushing effect, it also prevents wastewater from flowing into the electrical wall, ensuring the reliability of the wax boiling and flushing machine.

[0029] In a further preferred embodiment, the wax boiling and wax flushing machine also includes at least one spray pipe and a nozzle placement slot, the spray pipe is used to spray hot water, water vapor mixture and / or water vapor, and is made of flexible material or semi-flexible material; the nozzle placement slot is used to place the nozzle of the spray pipe.

[0030] The effect of the above solution is that the spray tube made of flexible or semi-flexible materials allows the nozzle to be adjusted at different angles and positions to more accurately spray hot water, water vapor mixture and water vapor, ensuring that the spray can effectively cover every part that needs to be cleaned, thereby improving the dewaxing and cleaning effect. At the same time, the design of the nozzle placement slot provides a dedicated space for the storage of the spray tube, avoiding damage and contamination of the nozzle, and improving the cleanliness and maintenance convenience of the equipment. Combined with the overall function of the wax boiling and wax flushing machine, this design enables users to flexibly choose the appropriate spray method according to different cleaning needs to ensure the best cleaning effect for each wax mold. In addition, the flexible material of the spray tube can effectively reduce the risk of damage due to improper operation and extend the service life of the equipment.

[0031] Compared with the existing technology, the utility model provides a wax boiling and wax flushing machine with multiple working modes, including a wax boiling tank, a heating mechanism and a hot water spraying mechanism, and is also equipped with a steam boiler, a water vapor mixing spraying mechanism and a steam spraying mechanism. The steam boiler is used to generate water vapor, and the water vapor mixing spraying mechanism draws hot water and steam from the steam boiler for efficient wax flushing; the steam spraying mechanism directly sprays water vapor. The device provides four working modes: wax boiling, hot water wax flushing, water vapor mixed wax flushing and steam wax flushing. Wax boiling effectively heats the wax mold to enhance its fluidity; hot water wax flushing gently rinses the inner cavity of the wax mold; water vapor mixed wax flushing uses the expansion of steam to generate a strong impact force, which can effectively remove the wax liquid without damaging the fragile plaster model; steam wax flushing penetrates into tiny gaps to ensure the cleanliness of the model and improve the casting quality. Each spraying mechanism draws water and steam from the steam boiler, integrating functions so that each mode can work in a coordinated manner. In addition, the modular design allows users to flexibly choose working modes, maximize the wax removal effect, smoothly switch between modes, significantly shorten operation time, and improve production efficiency; it not only adapts to the needs of different patients and meets the cleaning requirements of complex wax models, but also reduces the risk of model damage caused by operational errors, optimizes user experience, simplifies the process, makes denture production more efficient and accurate, and improves the quality of the final product.

[0036] The present invention provides a wax boiling and flushing machine with multiple working modes. In order to make the purpose, technical solution and effect of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples.

[0037] The utility model provides a wax boiling and wax flushing machine with multiple working modes, which provides four working modes, namely: wax boiling, hot water wax flushing, water vapor mixed wax flushing and steam wax flushing, among which wax boiling is the basis of wax flushing operation, which will melt the wax model and remove most of the wax liquid; steam wax flushing not only flushes away the residual wax liquid, but also removes the residual embedding material and even other impurities, which can be regarded as the last step of wax removal; hot water wax flushing and water vapor mixed wax flushing are selected for use according to different situations. Of course, it is not ruled out that the two modes can cooperate to deal with more complicated situations. The impact force of hot water wax flushing is relatively mild. For the inner cavity of the gypsum model that can be opened and exposed (the cavity formed after the wax model melts and flows out, where the original wax model is located), the gentle water flow can not only take away most of the residual wax and other impurities on the surface of the gypsum model, but also can Protect the plaster model from being damaged by large impact; and for some situations where it is not suitable to open the box (for example, the plaster model structure is relatively complex, opening the box may cause loss of details on the model surface and damage to fragile areas of the structure, so it is not suitable to open the box for wax flushing), the water vapor mixture combines the advantages of hot water and water vapor. Although the impact force generated is relatively large, the impact force of the water vapor mixture mainly comes from the expansion of the gas and the transfer of heat. Therefore, this impact force has better permeability and can effectively enter the tiny gaps of the model without causing excessive physical impact. In general, although the impact force of the water vapor mixture is large, it is different from the direct impact method of pure water. It is mainly based on gas penetration and is softer. Therefore, it can ensure the surface quality of the plaster model. It is suitable for non-opening structures with complex cavities and flow channels, and can perform high-quality wax flushing operations.

[0038] The above content is one of the main improvements of the present invention. To achieve the above functions, the present invention provides a wax boiling and wax flushing machine with multiple working modes, including: a wax boiling tank 100 (such as Figure 3 As shown), heating mechanism (not shown), hot water spraying mechanism 200 (as shown Figure 3 As shown), a steam boiler (not shown), a water vapor mixing injection mechanism and a steam injection mechanism (because in a further preferred embodiment the two share a common injection pipe, they are uniformly labeled as 300, as shown Figure 1The wax boiling tank 100, heating mechanism, and hot water spray mechanism 200 are existing structures in the prior art, but the present invention has been optimized and improved in a further preferred embodiment, which will be described in detail below and will not be repeated here. The steam pot, water vapor mixing spray mechanism, and steam spray mechanism are the main improvements of the present invention, wherein the steam pot is used to generate water vapor, the water vapor mixing spray mechanism is used to draw hot water and water vapor from the steam pot to spray the water vapor mixture for wax flushing, and the steam spray mechanism is used to draw water vapor from the steam pot to spray water vapor for wax flushing.

[0039] The utility model improves the applicability of the wax boiling and wax flushing machine by providing a variety of different working modes, so that it can perform different wax flushing treatments for plaster models with different needs. On this basis, it also adds a function of using steam for final surface cleaning, so that the original two-stage single wax boiling and wax flushing method is changed into a three-stage two-part wax boiling and wax flushing surface cleaning wax removal process; that is, the utility model not only improves the structure of the existing wax boiling and wax flushing machine, but also optimizes the existing wax removal process, improves the surface quality of the plaster model, and solves the problem that the existing wax flushing machine adopts a single boiling water spray structure, resulting in poor wax flushing effect due to individual differences of patients and the choice of whether to open the box or not. Moreover, the present invention draws hot water from the steam boiler by closely integrating the hot water spray mechanism 200 and the water vapor mixed spray mechanism with the wax boiling tank 100 and the steam boiler, and cleverly utilizes the "boil the wax first and then flush the wax" process in the wax removal process. On the one hand, it achieves a deep integration of the wax boiling tank 100, the heating mechanism, the hot water spray mechanism 200, and the water vapor mixed spray mechanism, significantly reducing the number of components, simplifying the complexity of the equipment, and improving the reliability of the equipment. On the other hand, it also effectively reduces the time required to heat water for the hot water spray and the water vapor mixed spray, thereby improving the wax removal efficiency. Compared with the mode in the prior art where the wax boiling and wax flushing mechanisms operate independently and heat water separately, this design avoids unnecessary operation, ensures that hot water and water vapor can be used in a timely manner when needed, and improves the efficiency and convenience of the overall operation.

[0040] In a further preferred embodiment of the present invention, the wax boiling and wax flushing machine adds at least one spray pipe and a nozzle placement slot. The spray pipe is made of flexible or semi-flexible material, so that the nozzle can be adjusted at different angles and positions as needed to ensure that hot water, water vapor mixture and water vapor can be accurately sprayed to each part that needs to be cleaned, thereby significantly improving the dewaxing and cleaning effects. At the same time, the design of the nozzle placement slot provides a special storage space for the nozzle of the spray pipe, effectively avoiding damage and contamination of the nozzle, and improving the cleanliness and maintenance convenience of the equipment. Combined with the overall function of the wax boiling and wax flushing machine, this design allows users to flexibly choose a suitable spraying method according to different cleaning needs, ensuring that the cleaning effect of each wax mold is optimal. In addition, the flexible material of the spray pipe is also conducive to reducing the risk of damage due to improper operation, thereby extending the service life of the equipment.

[0041] It is understandable that the above scheme can also be replaced by the following schemes: (1) using a design with a fixed spray tube and a multi-directional adjustable nozzle. Although this scheme is slightly less flexible, it can achieve different spray angles through a mechanical rotating device, which is suitable for occasions where fixed-point cleaning is required (for example, this method can be used for large-scale production of the same type of dentures, full dentures, identical half dentures, etc., but is not suitable for processing multiple types of dentures with large differences in structure); (2) introducing an automated control system, using sensors to detect the surface state of the wax model and automatically adjust the nozzle position and spray mode (comparatively speaking, this method is more expensive and more difficult to control).

[0042] Preferably, in the design of the wax boiling and wax flushing machine, a switch 410 and a first spray pipe 310 are added, such as Figure 4 As shown, the water vapor mixing injection mechanism and the steam injection mechanism share the injection pipe. This setting effectively reduces the complexity and manufacturing cost of the equipment, while improving the convenience of operation. The user can flexibly choose to inject water vapor mixture or water vapor by switching the switch 410 to quickly adapt to different cleaning needs. The solution of sharing the injection pipe not only reduces the number of components and reduces the failure rate, but also enhances the stability and reliability of the overall system, ensuring rapid conversion between water vapor mixing and steam injection. The above setting is conducive to meeting the individual differences of different patients without hindering the cleaning effect, thereby improving the quality and efficiency of denture production.

[0043] Available alternatives include: (1) using separate spray tubes for water vapor mixture and water vapor, which improves the specificity of each, but increases the complexity and maintenance cost of the equipment; (2) introducing an electronic control system to automatically switch the spray mode, which improves the level of automation but also increases the risk of system failure. Compared with these alternatives, the design of the utility model reduces the complexity and failure rate of the equipment while maintaining flexible operation, ensuring that users can quickly adapt to different cleaning needs, thereby better meeting the high standards required for denture production.

[0044] Preferably, the wax boiling and wax flushing machine is equipped with a foot switch, through which the user can control the spraying of the first spray tube 310. This setting allows the user to flexibly start or stop the spraying when cleaning is required, effectively reducing the risk of misoperation caused by manual operation. During the cleaning process, the instant responsiveness of the foot switch allows the user to more accurately adjust the spray time and intensity to meet the cleaning needs of different wax models. Especially when dealing with complex wax models or small plaster models, this design can also reduce accidental impacts on the model surface, protect details, and thus improve the quality of the produced dentures.

[0045] Of course, the above settings can also be replaced by the following solutions: (1) manual control switch. Although this solution can achieve basic spray control, it lacks flexibility and is prone to operational delays and misoperation; (2) automatic sensor control. This solution can automatically adjust the spray according to the cleaning needs of the wax model, but it increases the complexity and failure rate of the equipment. In contrast, the foot switch design of the utility model is not only easy to operate, but also can quickly respond to user needs, enhance the operability of the equipment, ensure the protection of the model during the cleaning process, and thus improve the overall cleaning effect and the quality of denture production.

[0046] Furthermore, the hot water spraying mechanism 200 includes a second spraying pipe 210 (such as Figure 4The second spray pipe 210 is equipped with a second spraying pipe 210 (not shown) and a gear regulating valve (not shown) to allow the user to draw hot water from the steam pot for spraying, so as to achieve the adjustability of the spray water flow rate and flow rate, thereby greatly improving the flexibility and accuracy of cleaning. Users can freely adjust the spray flow rate according to the shape and complexity of different wax models to ensure that the appropriate intensity is selected. This is especially important when dealing with wax models with complex details or fragile wax models. By optimizing the water flow rate, the residual wax liquid can be effectively removed while avoiding excessive impact on the surface of the model, thereby reducing the potential risk of damage. In addition, the gear regulating valve enhances the adaptability of the equipment and can meet diverse cleaning needs, whether it is a quick rinse of simple wax models or a deep cleaning of complex details. It is worth mentioning that the water flow sprayed by the second spray pipe 210 comes directly from the wax boiling tank 100, which enables the wax boiling tank 100 to not only melt the wax model, but also serve as a storage chamber for hot water, thereby improving the integration of various functions, reducing the number of parts, reducing the volume, and reducing production costs and floor space.

[0047] The above preferred embodiments can also be replaced by the following solutions: (1) fixed flow rate spray device, which can only provide a single spray intensity, lacks flexibility, and easily leads to ineffective processing under different cleaning requirements; (2) automatic adjustment spray system, although it can automatically adjust according to water flow requirements, the system complexity is high, which will lead to increased failure rate and maintenance difficulty. In contrast, the hot water spray mechanism 200 of the present invention maintains efficient cleaning ability and ensures the simplicity of equipment operation through a simple gear adjustment valve and an adjustable second spray pipe 210, reducing the risk of failure, thereby improving the cleaning effect and user experience.

[0048] In specific implementation, the design of the wax boiling and wax flushing machine also includes a steam pot control switch 420 and a steam pot status indicator light 430, such as Figure 4 As shown, this combination greatly improves the operational safety and user-friendliness of the equipment. Users can easily start or stop the steam boiler through simple switch controls, effectively managing the generation and use of steam, thereby preventing accidents caused by improper operation. At the same time, the indicator light provides real-time feedback to ensure that users can clearly understand the on status of the steam boiler during the cleaning process, avoiding incomplete cleaning or damage to the model due to misoperation. In conjunction with the use of the foot switch, users can flexibly adjust the timing of steam use and smoothly switch to other cleaning modes, ensuring the best cleaning effect when processing complex wax models, further improving the quality and efficiency of denture production.

[0049] The above settings can also be replaced by the following solutions: (1) manually adjusting the steam boiler. Although this solution is simple, it lacks real-time feedback. Users are likely to perform other operations without noticing that the steam boiler is on, which increases the risk of misoperation; (2) automated control systems. Although they can automatically manage the opening and closing of steam, the system complexity is high, the maintenance difficulty increases, and the frequency of failures is easily increased. Compared with these alternative solutions, the present invention maintains an efficient operating experience and reduces the risk of failure through a simple and clear switch control and indicator light design, ensuring the safety of users during use and the cleaning effect, thereby improving overall work efficiency.

[0050] Furthermore, the utility model introduces a water level sensor (not shown) in the design of the wax boiling and wax flushing machine. The water level sensor can monitor the water level in the steam pot in real time and accurately judge the sufficiency of water. When the water level is lower than the safety threshold, the system will automatically cut off the heating source to prevent the steam pot from drying out due to lack of water. This function not only effectively protects the equipment itself and extends its service life, but also reduces the safety hazards caused by equipment failure. In addition, the water level sensor is combined with the water supply device to replenish water in time when the water level reaches the preset threshold, ensuring a continuous supply of steam, thereby optimizing the cleaning process and improving work efficiency. Users do not have to worry about the steam pot overheating during operation, and can focus more on the cleaning task, improving the overall user experience.

[0051] Available alternatives include: (1) manual water level detection, which requires users to check the water level regularly, increasing the risk of manual operation and easily leading to dry burning accidents due to water shortage; (2) simple mechanical float switch. Although this solution can prevent dry burning, its reaction speed and sensitivity are low, and it cannot respond in time when the water level fluctuates. In contrast, the utility model not only greatly improves safety through real-time monitoring and automatic control, but also optimizes steam output and equipment reliability. Users do not need to worry about water level issues, thereby improving work efficiency and cleaning effects, and meeting the high-standard denture production requirements.

[0052] Similar to the arrangement of the steam pot control switch 420 and the steam pot status indicator light 430, the present invention also introduces a wax boiling tank control switch 440 and a wax boiling tank status indicator light 450 into the design of the wax boiling and wax flushing all-in-one machine in a further preferred embodiment. Figure 4As shown, the device improves operational convenience and enhances safety. Users can directly control the wax boiling tank 100's start and stop with a simple switch, achieving flexibility in wax model processing. At different operating stages, users can quickly adjust the device's status to ensure the wax model reaches the appropriate temperature, thereby optimizing the wax removal effect. Furthermore, the status indicator provides real-time feedback to users, allowing them to clearly understand the operating status of the wax boiling tank 100, avoiding equipment damage or safety hazards caused by misoperation and ensuring a more efficient and reliable cleaning process.

[0053] According to another aspect of the present invention, the integrated wax-boiling and wax-washing machine further includes a wax-washing station, which is located above and to the side of the wax-boiling tank 100 and is connected to the tank 100 so that the water after wax washing can flow back into the wax-boiling tank 100. By locating the wax-washing station above and to the side of the wax-boiling tank 100 and connecting it thereto, the wastewater generated during the washing process can flow directly back into the wax-boiling tank 100, reducing water waste and achieving water recycling. This allows the device to maintain an optimal water level and temperature during the wax-removing operation (water drawn from the water source requires a certain amount of time to heat up. Hot water is drawn from the steam boiler during wax washing, and the hot water after wax washing flows back into the wax-boiling tank 100, forming a water cycle that reduces the time required for water heating). This improves the cleaning effect. Furthermore, the need for external water sources during the cleaning process is reduced, lowering operating costs and making it particularly suitable for large-scale denture production. Furthermore, the connection design between the wax-boiling station and the wax-boiling tank 100 simplifies the overall structure of the device, making it more convenient to operate, allowing users to easily perform cleaning and maintenance, and improving work efficiency.

[0054] Further, such as Figure 3 As shown, the bottom of the wax rinsing station is provided with a through-groove, and a return plate 510 is provided directly below. A return gap 520 is reserved between the return plate 510 and the bottom of the wax rinsing station. The wax rinsing station is connected to the wax boiling tank 100 through the through-groove and the return gap 520. The presence of the through-groove allows wastewater generated during the wax rinsing process to flow smoothly to the return plate 510 and then efficiently return to the wax boiling tank 100 through the reserved return gap 520. This not only prevents the accumulation of wastewater on the rinsing station, reducing the complexity of cleaning and maintenance, but also ensures that the temperature and composition of the rinsing water can be recovered in a timely manner, maintaining the efficient operation of the system. If wastewater accumulates on the rinsing station, the residual wax and embedding material in the wastewater are likely to re-adhere to the plaster model. The provision of the through-groove effectively avoids this problem. Combined with the provision of the return plate 510 and the return gap 520, while ensuring the wax rinsing effect, it also prevents wastewater from flowing into the electrical wall, ensuring the reliability of the wax boiling and rinsing all-in-one machine.
