Abstract
Description
A mica heater with temperature control function Technical Field
[0001] This utility model relates to the field of mica heaters, and more particularly to a mica heater with temperature control function. Background Technology
[0002] Heaters are a common type of heating device and are widely used in various household appliances and industrial equipment. Heaters convert electrical energy into heat energy through heating elements to achieve the purpose of heating and sterilization.
[0003] However, traditional heaters often cannot accurately adjust and maintain the set temperature, resulting in large temperature fluctuations during the sterilization process and failing to achieve the desired sterilization effect. In addition, due to unreasonable layout of heating elements and temperature control methods, traditional heaters cause some areas to be too hot while other areas are too cold, resulting in uneven heat distribution. This not only easily leads to incomplete sterilization but also affects the lifespan of the heated items themselves. This is especially true in baby sterilizers, where items such as baby bottles and nipples are highly sensitive to temperature. The deficiencies of traditional heaters in temperature control accuracy and heat distribution result in unstable sterilization effects, failing to fully meet the high standards required for sterilizing baby products.
[0004] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

[0029] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.
[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0032] As shown in Figures 1 to 4, this utility model embodiment provides a mica heater with temperature control function, including a first conductor 11, a second conductor 12, an insulating frame 3, a first heating wire 41, a second heating wire 42, a first temperature controller 51, a second temperature controller 52, and a fuse 6. The insulating frame 3 is made of mica sheet. A first winding support 31 and a second winding support 32 are respectively provided on both sides of the insulating frame 3. The first heating wire 41 is wound on the first winding support 31, and the second heating wire 42 is wound on the second winding support 32. The first winding support 31 and the second winding support 32 are provided to better support and fix the first heating wire 41 and the second heating wire 42, avoid deformation or displacement of the heating wire, and avoid local overheating, so that the heat is evenly distributed, reducing the temperature unevenness caused by heat concentration on one side, thereby improving the overall heating efficiency.
[0033] The first wire 11 is connected to one end of the first heating wire 41, and the other end of the first heating wire 41 is connected to one end of the fuse 6 through the first thermostat 51. The other end of the fuse 6 is connected to one end of the second thermostat 52 through the connecting piece 61. The other end of the second thermostat 52 is connected to one end of the second heating wire 42, and the other end of the second heating wire 42 is connected to the second wire 12. The first heating wire 41 and the second heating wire 42 are connected in series. The current flows from the first conductor 11 to the first heating wire 41 and then through the second heating wire 42, so that the first heating wire 41 and the second heating wire 42 work together to achieve heating. The first temperature controller 51 can monitor the temperature of the first heating wire 41 in real time. When the temperature reaches the set value, the first temperature controller 51 will control the amount of current flowing in, thereby preventing the first heating wire 41 from overheating. The second temperature controller 52 can adjust the temperature of the second heating wire 42. When the temperature of the second heating wire 42 is too high, the second temperature controller 52 will adjust the current or cut off the power supply to avoid overheating and improve the operating safety of the heater. The fuse 6 serves as a safety protection element. Once an abnormal current occurs in the circuit, the fuse 6 can cut off the circuit to protect the heater from damage. This configuration can greatly improve the safety and stability of the heating process.
[0034] As shown in Figure 4, the first winding support 31 further includes a longitudinal winding plate 311 and a transverse winding plate 312. The longitudinal winding plate 311 and the transverse winding plate 312 are staggered and spliced within the insulating frame 3. Both the longitudinal winding plate 311 and the transverse winding plate 312 have winding clamping grooves 300 on their outer sides. These winding clamping grooves 300 are used to fix the first heating wire 41. The staggered splicing structure of the longitudinal winding plate 311 and the transverse winding plate 312 provides a firm support for the first heating wire 41. The winding clamping grooves 300 can clamp the first heating wire 41, thereby preventing the first heating wire 41 from shifting due to overheating expansion or vibration during the heating process.
[0035] As shown in Figure 4, furthermore, the longitudinal winding plate 311 is provided with a first hollow groove 3111, and the first temperature controller 51 is embedded in the first hollow groove 3111. The hollow groove provides an independent installation space for the first temperature controller 51, allowing it to be tightly embedded in the longitudinal winding plate 311, thereby saving space and improving the compactness of the overall structure; in addition, the hollow groove can also promote air circulation around the first temperature controller 51, thereby improving the heat dissipation effect of the first temperature controller 51.
[0036] As shown in Figure 4, the system further includes a cross-shaped fixing bracket 313, which is located at the bottom connection between the longitudinal winding plate 311 and the transverse winding plate 312, thereby improving the assembly stability between the longitudinal winding plate 311 and the transverse winding plate 312 and preventing the structure from loosening.
[0037] As shown in Figure 4, the longitudinal winding plate 311 is further provided with a second hollow groove 3112, and the fuse 6 is embedded in the second hollow groove 3112.
[0038] As shown in Figure 1, the second winding support 32 has the same structure as the first winding support 31, and a baffle 33 is provided between the first winding support 31 and the second winding support. The baffle 33 can play a role in isolation and protection. The baffle 33 separates the first winding support 31 and the second winding support 32, preventing the first heating wire 41 and the second heating wire 42 on both sides from getting too close, thereby isolating the mutual interference of heat and improving the working stability and safety of the heater.
[0039] Furthermore, the diameters of the first heating wire 41 and the second heating wire 42 are 0.15-0.6 mm. In this embodiment, the diameter of both the first heating wire 41 and the second heating wire 42 is 0.35 mm.
[0040] Furthermore, both the first wire winding support 31 and the second wire winding support 32 are made of mica sheets. Mica has excellent high temperature resistance and electrical insulation properties, which prevents the heater from deforming or being damaged at high temperatures. In addition, mica has high mechanical strength and is corrosion resistant, which can improve the stability and durability of the heater.
[0041] As shown in Figure 1, both the first conductor 11 and the second conductor 12 are provided with terminals 10 at their ends. The terminals 10 can be quickly connected to other electrical components, making installation and use convenient.
[0042] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
