Description

Technical Field

[0001] This application relates to the field of dental prosthesis manufacturing equipment technology, and more particularly to a wax melting device based on dental prosthesis processing. Background Technology

[0002] A published patent document with announcement number CN222288716U discloses a wax melting device for denture processing, including a housing, a wax melting tank, a C-shaped retaining spring, and a heating device. The wax melting tank is embedded in the housing, and the heating device is located at the bottom of the wax melting tank. The wax melting tank is bent outward near the opening to form a bent portion, and the lower part of the bent portion abuts against the upper surface of the housing. An annular groove is formed circumferentially on the outer wall of the wax melting tank, and the annular groove is near the bent portion. The C-shaped retaining spring is engaged in the annular groove, and the top of the C-shaped retaining spring abuts against the upper surface of the housing. In this invention, the wax melting tank bends outward near the opening, and then the C-shaped retaining spring secures the wax melting tank to the housing, preventing the wax melting tank from falling out of the housing when the wax melting device is placed upside down.

[0003] In practical use, the above devices are inefficient and prone to burns because the wax at the edge of the melting tank solidifies easily due to rapid heat dissipation. Therefore, this application provides a wax melting device based on denture processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a wax melting device based on denture processing, which overcomes the deficiencies of existing technologies and aims to solve the problem that in actual use, the wax at the edge of the melting tank is prone to solidification due to rapid heat dissipation, requiring manual scraping, which is inefficient and can easily cause burns.

[0005] To achieve the above objectives, this application provides the following technical solution: a wax melting device based on denture processing, comprising an outer shell, a heater disposed inside the outer shell, a wax melting mechanism mounted above the heater inside the outer shell, the wax melting mechanism comprising a wax melting box disposed inside the outer shell, an extension fixedly connected to the top of the wax melting box, an inclined guide ring fixedly connected to the inner wall of the extension, an electric heating layer fixedly installed on the inner wall of the extension, a top cover placed on the top of the outer shell, a wax scraping mechanism disposed at the bottom of the top cover, the wax scraping mechanism comprising an inner cover fixedly connected to the bottom of the top cover, two sets of electric push rods fixedly installed at the bottom end of the inner cover, a rectangular box fixedly installed at the telescopic ends of the two sets of electric push rods, several sets of elastic mechanisms installed around the rectangular box, a scraper installed at the end of the elastic mechanism away from the rectangular box, and one side of the electric push rod abutting against the inclined guide ring.

[0006] By adopting the above technical solution, denture wax is placed inside the wax melting box. The wax is heated by turning on the heater. The inclined guide ring is angled, with its bottom angled end located at the inlet of the wax melting box. Therefore, the inclined guide ring guides the molten wax from the edges into the wax melting box for heating. Simultaneously, the temperature of the extension section can be independently controlled through the cooperation of the electric heating layer and the heater, ensuring that the denture wax at the edges is heated evenly, improving the uniformity of heating. Meanwhile, an electric push rod drives a rectangular... The box and scraper move up and down, allowing the scraper to remove the wax from the inclined guide ring, causing the wax to fall automatically into the melting wax box. The top cover also helps prevent wax splattering. The scraper, under the elastic action of the elastic mechanism, automatically adjusts its extension and retraction according to the inclination of the inclined guide ring, smoothly scraping away the wax or wax blocks. The heating layer improves the heating effect on the wax located at the edge of the melting wax box. The electric push rod, elastic mechanism, and scraper automatically remove the wax or wax blocks from the edge, improving scraping efficiency.

[0007] As a preferred technical solution of this application, the elastic mechanism includes an outer protective cover, which is fixedly installed on the outer wall of the rectangular box. An inner protective cover is slidably connected inside the outer protective cover. A spring is installed between the outer protective cover and the inner protective cover. One end of the inner protective cover is fixedly installed on one side of the scraper.

[0008] By adopting the above technical solution, the spring provides an elastic extension and contraction effect when the scraper moves up and down along the inclined surface of the inclined guide ring, so that the scraper can always be in contact with the inclined surface of the inclined guide ring and move up and down smoothly. At the same time, the inner protective cover slides inside the outer protective cover following the elastic extension and contraction of the spring. The outer and inner protective covers improve the protection effect of the spring.

[0009] As a preferred technical solution of this application, a controller is fixedly installed on the outer wall of the outer shell, and a temperature sensor is fixedly installed inside the inclined guide ring. The temperature sensor and the heating layer are both electrically connected to the controller.

[0010] By adopting the above technical solution, the controller receives the temperature value of the inclined guide ring detected by the temperature sensor, and adjusts the opening and closing of the heating layer according to the difference between the temperature value of the inclined guide ring and the preset value, thereby improving the automatic control effect of the temperature of the inclined guide ring.

[0011] As a preferred technical solution of this application, the number of the wax melting boxes and heaters are both 3 sets, and the size of the three sets of wax melting boxes is two small and one large.

[0012] By adopting the above technical solution, and using three sets of wax melting boxes, two small and one large, the appropriate wax melting box can be flexibly selected according to the processing scale and type of dental wax, which is conducive to meeting the processing needs of different scales and types of dental prostheses and improving the applicability of this device.

[0013] As a preferred technical solution of this application, the bottom of the molten wax box is provided with an annular groove, which is adapted to the corresponding heater.

[0014] By adopting the above technical solution, the annular groove is adapted to the heater, so that the annular groove is stuck on the heater to fix the molten wax box, thereby improving the installation efficiency and heating effect of the molten wax box.

[0015] As a preferred technical solution of this application, a heat-conducting block is fixedly installed at the bottom of the molten wax box, and the heat-conducting block is located in the middle of the annular groove.

[0016] By adopting the above technical solution, the heat from the heater is absorbed and transferred to the bottom of the molten wax box through the heat-conducting block. Combined with the position of the heater, the heating uniformity of the molten wax box is improved.

[0017] As a preferred technical solution of this application, a handle is fixedly installed on the top of the top cover.

[0018] By adopting the above technical solution, the top cover is made easier to pick up with the handle, which improves the practicality of connecting and separating the top cover from the outer shell.

[0019] As a preferred technical solution of this application, the spring is provided with a telescopic guide rod inside.

[0020] By adopting the above technical solution, the spring is guided by the telescopic guide rod, which helps to maintain stable pressure of the scraper during the wax scraping process and improves its practicality in use.

[0021] The beneficial effects of this application are:

[0022] 1. Place the denture wax inside the melting wax box. Heat the denture wax by turning on the heater. The inclined guide ring is angled, with its bottom angled end located at the inlet of the melting wax box. Therefore, the inclined guide ring guides the molten wax from the edges into the melting wax box for heating. Simultaneously, the electric heating layer and heater work together to independently control the temperature of the extension section, ensuring that the denture wax at the edges is heated evenly. Meanwhile, the rectangular box is driven by an electric push rod. The scraper moves up and down, scraping the wax on the inclined guide ring and causing it to fall automatically into the melting wax box. The top cover also helps prevent wax splattering. The scraper, under the elastic action of the elastic mechanism, automatically adjusts its extension and retraction according to the inclination of the inclined guide ring, smoothly scraping the wax or wax blocks. The heating layer improves the heating effect on the wax at the edge of the melting wax box. The electric push rod, elastic mechanism, and scraper automatically remove the wax or wax blocks from the edge, improving scraping efficiency.

[0023] 2. When the spring moves up and down along the inclined surface of the inclined guide ring, it provides an elastic extension effect, so that the scraper can always be in contact with the inclined surface of the inclined guide ring and move up and down smoothly. At the same time, the inner cover slides inside the outer cover following the elastic extension and contraction of the spring. The outer and inner covers improve the protection of the spring.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-4 A wax melting device based on denture processing includes an outer shell 1, a heater 2 disposed inside the outer shell 1, and a wax melting mechanism 3 installed above the heater 2 inside the outer shell 1. The wax melting mechanism 3 includes a wax melting box 301 placed inside the outer shell 1. An extension 302 is fixedly connected to the top of the wax melting box 301, an inclined guide ring 303 is fixedly connected to the inner wall of the extension 302, and an electric heating layer 304 is fixedly installed on the inner wall of the extension 302. A top cover 4 is placed on the top of the outer shell 1, and a wax scraping mechanism 5 is disposed at the bottom of the top cover 4. The wax scraping mechanism 5 includes an inner cover 501. The inner cover 501 is fixedly connected to the bottom of the top cover 4. Two sets of electric push rods 502 are fixedly installed at the bottom of the inner cover 501. A rectangular box 503 is fixedly installed at the telescopic end of the two sets of electric push rods 502. Several sets of elastic mechanisms 504 are installed around the rectangular box 503. A scraper 505 is installed at the end of the elastic mechanism 504 away from the rectangular box 503. One side of the electric push rod 502 abuts against the inclined guide ring 303. A controller 8 is fixedly installed on the outer wall of the outer shell 1. A temperature sensor 9 is fixedly installed inside the inclined guide ring 303. The temperature sensor 9 and the heating layer 304 are both electrically connected to the controller 8.

[0031] Dental wax is placed inside the wax melting box 301. The heater 2 is activated to heat the wax. An inclined guide ring 303, with its inclined bottom end located at the inlet of the wax melting box 301, guides the wax from the edges into the melting box 301 for heating. Simultaneously, the heating layer 304, in conjunction with the heater 2, allows independent temperature control of the extension section 302, ensuring the wax at the edges is heated evenly. Meanwhile, an electric push rod 502 moves the rectangular box 503 and scraper 505 up and down, causing the scraper 505 to scrape the wax off the inclined guide ring 303, allowing the wax to automatically fall into the wax melting box 301. Within 01, and with the cover 4 providing shielding, wax splashing is prevented. The scraper 505, under the elastic action of the elastic mechanism 504, automatically extends and retracts according to the inclination of the inclined guide ring 303, smoothly scraping off the wax or wax blocks. The heating layer 304 improves the heating effect on the wax located at the edge of the melting wax box 301. The electric push rod 502, elastic mechanism 504, and scraper 505 automatically scrape off the wax or wax blocks at the edge, improving scraping efficiency. The controller 8 receives the temperature value of the inclined guide ring 303 detected by the temperature sensor 9, and adjusts the opening and closing of the heating layer 304 according to the difference between the temperature value of the inclined guide ring 303 and the preset value, improving the automatic control effect of the temperature of the inclined guide ring 303.

[0032] Reference Figure 1-3 The elastic mechanism 504 includes an outer cover 5041, which is fixedly installed on the outer wall of the rectangular box 503. An inner cover 5042 is slidably connected inside the outer cover 5041. A spring 5043 is installed between the outer cover 5041 and the inner cover 5042. One end of the inner cover 5042 is fixedly installed on one side of the scraper 505. The number of wax melting boxes 301 and heaters 2 are both 3 sets, and the size of the three sets of wax melting boxes 301 is two small and one large.

[0033] The spring 5043 provides an elastic extension and contraction effect as the scraper 505 moves up and down along the inclined surface of the inclined guide ring 303, allowing the scraper 505 to always be in contact with the inclined surface of the inclined guide ring 303 and move up and down smoothly. At the same time, the inner protective cover 5042 slides inside the outer protective cover 5041 following the elastic extension and contraction of the spring 5043. The outer protective cover 5041 and the inner protective cover 5042 improve the protection effect of the spring 5043. With the three sets of wax melting boxes 301, two small and one large, the appropriate wax melting box 301 can be flexibly selected according to the processing scale and type of denture wax, which is conducive to meeting the processing needs of dentures of different scales and types and improving the applicability of this device.

[0034] Reference Figure 2-4The bottom of the wax melting box 301 is provided with an annular groove 6, which is adapted to the corresponding heater 2; a handle 10 is fixedly installed on the top of the top cover 4; by adapting the annular groove 6 to the heater 2, the annular groove 6 is locked on the heater 2 to fix the wax melting box 301, which improves the installation efficiency and heating effect of the wax melting box 301; the handle 10 makes it easy to take off the top cover 4, which improves the practicality of connecting and separating the top cover 4 from the outer shell 1.

[0035] Reference Figure 1 A heat-conducting block 7 is fixedly installed at the bottom of the wax melting box 301, and the heat-conducting block 7 is located in the middle of the annular groove 6; a telescopic guide rod 11 is provided inside the spring 5043; the heat of the heater 2 is absorbed by the heat-conducting block 7 and transferred to the bottom of the wax melting box 301, which, together with the position of the heater 2, improves the heating uniformity of the wax melting box 301; the telescopic guide rod 11 guides the spring 5043, which helps to keep the scraper 505 under stable pressure during the wax scraping process, thus improving its practicality in use.

[0036] Working principle: Dental wax is placed inside the melting wax box 301. The heater 2 is turned on to heat the dental wax. The inclined guide ring 303 is inclined, and its inclined bottom end is located at the inlet of the melting wax box 301. Therefore, the inclined guide ring 303 guides the wax at the edge into the melting wax box 301 for heating. At the same time, the temperature of the extension section 302 can be independently controlled by the electric heating layer 304 in cooperation with the heater 2, so that the dental wax at the edge is heated. Meanwhile, the electric push rod 502 drives the rectangular box 503 and the scraper 505 to move up and down, so that the scraper 505 scrapes the wax on the inclined guide ring 303, and the wax falls automatically into the melting wax box 301. Inside the wax melting box 301, and with the cover 4, the wax splashing is prevented. The scraper 505, under the elastic action of the elastic mechanism 504, automatically adjusts its extension and retraction according to the inclination of the inclined guide ring 303, so as to smoothly scrape off the wax or wax block. The spring 5043 provides an elastic extension and retraction effect when the scraper 505 moves up and down along the inclined surface of the inclined guide ring 303, so that the scraper 505 can always be in contact with the inclined surface of the inclined guide ring 303 and move up and down smoothly. At the same time, the inner protective cover 5042 slides inside the outer protective cover 5041 with the elastic extension and retraction of the spring 5043. The outer protective cover 5041 and the inner protective cover 5042 improve the protection of the spring 5043.

[0037] The controller 8 receives the temperature value of the inclined guide ring 303 detected by the temperature sensor 9, and adjusts the opening and closing of the heating layer 304 according to the difference between the temperature value of the inclined guide ring 303 and the preset value. The three sets of wax melting boxes 301 are of two small and one large size, so that the appropriate wax melting box 301 can be flexibly selected according to the processing scale and type of dental wax.

[0038] Meanwhile, the annular groove 6 is adapted to the heater 2, so that the annular groove 6 is locked on the heater 2 to fix the molten wax box 301; the heat conduction block 7 absorbs the heat of the heater 2 and transfers it to the bottom of the molten wax box 301, which, together with the position of the heater 2, improves the heating uniformity of the molten wax box 301.

[0039] In addition, the handle 10 facilitates the removal of the top cover 4; the telescopic guide rod 11 guides the spring 5043, which helps the scraper 505 maintain stable pressure during the wax scraping process.
