Description

Technical Field

[0001] This utility model relates to the field of resin heating equipment technology, and in particular to a resin heater. Background Technology

[0002] Currently known heating elements are all made of easily conductive metal and have several deep heating holes. The light-cured resin used in dentistry becomes softer when heated to a certain temperature, allowing for better results when filling cavities. Light-cured resin is usually packaged in a syringe, and the entire syringe must be inserted into the heating hole on the heating element for use. Existing resin heaters have external battery compartments, which take up a lot of space, are inconvenient to store, and are difficult to use. Utility Model Content

[0003] In order to address the technical deficiencies mentioned in the background art, the purpose of this utility model is to provide a resin heater.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A resin heater includes a heating cylinder, a base disposed at the lower end of the heating cylinder, a heating assembly, and a power supply assembly disposed within the base. The heating cylinder has multiple heating cavities with openings at their upper ends spaced apart. The base has an internal receiving cavity. The heating assembly is disposed between the base and the heating cylinder for heating the heating cylinder. The power supply assembly includes a circuit board, a power connector, and a switch. The circuit board is disposed within the base, and the power connector is disposed on the side wall of the base for connection to a power cord. The switch is disposed on the base, and the power connector, the switch, and the heating assembly are all electrically connected to the circuit board.

[0006] By adopting the above technical solution, the heating component and the power supply component are set inside the base. The heating component heats the heating cylinder, and the power supply component controls the working status of the heating component. It is simple to operate, convenient to use, occupies less space, and is easier to transport and store.

[0007] Furthermore, the heating assembly includes a heat-conducting plate, a temperature sensor, and a heating element. The heat-conducting plate is fixed to the upper end of the base, and the heating element is disposed between the heat-conducting plate and the circuit board. The heating element is in close contact with the heat-conducting plate, resulting in higher heat conduction efficiency. The temperature sensor is disposed on one side of the circuit board and electrically connected to the circuit board, improving the accuracy of temperature control.

[0008] Furthermore, the heating cavity is provided with multiple support columns. One end of each support column is threaded to the bottom wall of the base, and the other end of each support column is fixedly connected to the heat-conducting plate. This makes installation and disassembly more convenient, the structure simple, and cost-effective.

[0009] Furthermore, a first mounting hole is provided on the lower side of the heat-conducting plate, and the diameter of one end of the support column is larger than the diameter of the other end of the support column. The other end of the support column is inserted into the first mounting hole to improve assembly efficiency.

[0010] Furthermore, the heat-conducting plate is also provided with multiple second mounting holes. The upper surface of the circuit board is provided with multiple connecting posts, the ends of which are furthest from the circuit board and are inserted into the second mounting holes. This staggered, layered arrangement improves space utilization, reduces the product's size, and lowers costs.

[0011] Furthermore, the size of the heating element is smaller than that of the heat-conducting plate, saving costs. The upper surface of the heat-conducting plate is in close contact with the lower surface of the heating cylinder, improving the efficiency of heat conduction. The upper surface area of ​​the heat-conducting plate is the same as the lower surface area of ​​the heating cylinder, which ensures that the heating cylinder is heated evenly and improves the heating quality.

[0012] Furthermore, two wires are connected between the heating element and the temperature sensor. One end of the wire is connected to the upper end of the temperature sensor, and the other end of the wire is folded towards the center of the upper surface of the circuit board so that the other end of the wire is supported and connected to the lower surface of the heating element. This arrangement avoids misalignment and makes the structure more compact.

[0013] Furthermore, the power supply assembly also includes three indicator lights, each corresponding to a different temperature. When the indicator light is constantly on, the heating cylinder is in a heat preservation state. When the indicator light flashes, the heating cylinder is in a heating state, making the operating status easier to distinguish and the use more convenient.

[0014] Furthermore, the three indicator lights are arranged side by side at intervals on one side of the switch, making them easy to view and highly practical.

[0015] Furthermore, some of the heating chambers are configured with different sizes, which provides strong compatibility and allows them to be used to heat different raw materials.

[0016] In summary, the beneficial effects of this utility model are as follows:

[0017] In this invention, a heating component and a power supply component are installed inside the base. The heating component heats the heating cylinder, and the power supply component controls the working status of the heating component. It is simple to operate, convenient to use, occupies less space, and is easier to transport and store. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-4 The embodiments of this utility model will be described in further detail below.

[0028] A resin heater 1, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a heating cylinder 2, a base 3 disposed at the lower end of the heating cylinder 2, a heating assembly, and a power supply assembly disposed within the base 3. The heating cylinder 2 has multiple heating chambers 21 with openings at their upper ends spaced apart. The base 3 is housed within a receiving cavity 31, and the heating assembly is disposed between the base 3 and the heating cylinder 2 for heating the heating cylinder 2. The power supply assembly includes a circuit board 41, a power connector 42, and a switch 43. The circuit board 41 is disposed within the base 3, and the power connector 42 is disposed on the side wall of the base 3 for connection to a power cord. The switch 43 is disposed on the base 3, and the power connector 42, switch 43, and heating assembly are all electrically connected to the circuit board 41.

[0029] The heating component and the power supply component are located inside the base 3. The heating component heats the heating cylinder 2, and the power supply component controls the working status of the heating component. It is simple to operate, convenient to use, occupies less space, and is easier to transport and store.

[0030] In some embodiments, please refer to Figure 3 , Figure 4 The heating assembly includes a heat-conducting plate 51, a temperature sensor 52, and a heating element 53. The heat-conducting plate 51 is fixed to the upper end of the base 3. The heating element 53 is disposed between the heat-conducting plate 51 and the circuit board 41, and the heating element 53 is in close contact with the heat-conducting plate 51, resulting in higher heat conduction efficiency. The heating element 53 and the temperature sensor 52 are located on one side of the circuit board 41 and are electrically connected to the circuit board 41, improving the accuracy of temperature control.

[0031] Preferably, the heating cavity 21 is provided with multiple support columns 32. One end of the support column 32 is threaded to the bottom wall of the base 3, and the other end of the support column 32 is fixedly connected to the heat conduction plate 51. This makes installation and disassembly more convenient, the structure is simple, and the cost is saved.

[0032] Specifically, a first mounting hole is provided on the lower side of the heat-conducting plate 51, and the diameter of one end of the support column 32 is larger than the diameter of the other end of the support column 32. The other end of the support column 32 is inserted into the first mounting hole to improve the assembly efficiency.

[0033] Preferably, to facilitate the installation of the circuit board 41, the heat-conducting plate 51 is also provided with multiple second mounting holes. Multiple connecting posts 33 are provided on the upper surface of the circuit board 41. The ends of the connecting posts 33 furthest from the circuit board 41 are inserted into the second mounting holes. This staggered, layered arrangement improves space utilization, reduces the product's size, and lowers costs. Furthermore, the layered arrangement also improves heat dissipation, helps protect the circuit board 41 and other structures, and extends its service life.

[0034] In some embodiments, please refer to Figure 1 , Figure 3 The heating element 53 is smaller than the heat-conducting plate 51, saving costs. The upper surface of the heat-conducting plate 51 is in close contact with the lower surface of the heating cylinder 2, improving heat conduction efficiency. The upper surface area of ​​the heat-conducting plate 51 is the same as the lower surface area of ​​the heating cylinder 2, ensuring even heating of the heating cylinder 2 and improving heating quality. The upper end of the base 3 encloses the heat-conducting plate 51 within the receiving cavity 31. The heat-conducting plate 51 protrudes from the periphery of the heating cylinder 2 to form a sealed connection with the upper end of the base 3. The base 3 and the heating cylinder 2 together form a cylindrical structure, which prevents heat loss, improves energy utilization, and also helps improve assembly efficiency.

[0035] In some embodiments, please refer to Figure 3 , Figure 4 Two wires 54 are connected between the heating element 53 and the temperature sensor 52. One end of the wire 54 is connected to the upper end of the temperature sensor 52, and the other end of the wire 54 is folded towards the center of the upper surface of the circuit board 41 so that the other end of the wire 54 is supported and connected to the lower surface of the heating element 53. This arrangement avoids misalignment and makes the structure more compact.

[0036] In some embodiments, please refer to Figure 1 The power supply unit also includes three indicator lights 44, which correspond to three different temperatures. When an indicator light 44 is constantly lit, the heating cylinder 2 is in a heat preservation state. When an indicator light 44 flashes, the heating cylinder 2 is in a heating state. The working status is easier to distinguish, making it more convenient to use.

[0037] Specifically, three indicator lights 44 are arranged side by side at intervals on one side of switch 43, making them easy to view and highly practical.

[0038] Each indicator light 44 corresponds to a heating temperature, and three heating temperatures can be preset: 45℃, 50℃, and 55℃. After the switch 43 is turned on, pressing the switch 43 once will increase the temperature by one level. When the indicator light 44 flashes, it indicates that the heating element is heating. When the set temperature is reached, the indicator light 44 will remain on, and the heating element will be in heat preservation mode.

[0039] In some embodiments, please refer to Figure 1 The heating chambers 21 are designed with different dimensions, which is highly compatible and can adapt to heating different raw materials. Different sizes of heating chambers 21 can be selected according to the amount of material used, saving materials and reducing the adverse effects of repeated heating on the raw materials. In particular, the diameter of the heating chamber 21 can be changed to change the size of the heating chamber 21. The heating chambers 21 are designed with the same depth but different diameters, which helps to improve heating efficiency.
