Description

Technical Field

[0001] This utility model relates to infrared heating lamps, and more particularly, to an infrared heating lamp with precise temperature control. Background Technology

[0002] Currently, Chinese patent CN219145629U discloses an infrared heating lamp with a reflective focusing coating, comprising a transparent glass tube, an infrared heating wire disposed within the glass tube, and insulating and sealing ceramic heads disposed at both ends of the glass tube. The insulating and sealing ceramic heads are provided with conductive leads electrically connected to the infrared heating wire. However, the aforementioned infrared heating lamp cannot detect and control the intensity of its infrared radiation during operation, resulting in unstable heating performance. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide an infrared heating lamp with precise temperature control, which has the advantage of being able to detect and control the intensity of infrared radiation during use, resulting in a more stable heating effect.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an infrared heating lamp with precise temperature control, comprising a transparent lampshade, an infrared heating wire disposed inside the transparent lampshade, a conductive lead wire passing through the transparent lampshade, a temperature measuring element fixedly disposed in the transparent lampshade, and a transmission wire electrically connected to the temperature measuring element, wherein the inner end of the conductive lead wire is electrically connected to the infrared heating wire.

[0005] The above technical solution connects the temperature sensing element to an external controller via a transmission wire, and at the same time, the infrared heating wire is connected to a power supply equipped with the controller via a conductive lead.

[0006] In use, the temperature sensing element can detect the temperature inside the transparent lampshade and convert the detected data into an electrical signal, which is transmitted to the controller in real time via a transmission wire. After receiving the electrical signal, the controller converts it into temperature data and compares it with preset data. When the detected temperature is lower than the preset data, the controller will increase the input current of the infrared heating lamp, thereby increasing the infrared radiation intensity of the infrared heating lamp. When the detected temperature is higher than the preset data, the controller will decrease the input current of the infrared heating lamp, thereby reducing the infrared radiation intensity of the infrared heating lamp.

[0007] As described above, the infrared heating lamp can detect and control the intensity of infrared radiation during use, resulting in a more stable heating effect.

[0008] Preferably, the conductive lead is disposed through the lower end of the transparent lampshade.

[0009] With the above technical solution, the conductive lead is installed through the lower end of the transparent lampshade, which has the advantage of making installation more convenient.

[0010] Preferably, the temperature measuring element is disposed inside the transparent lampshade, and all the transmission wires pass through the transparent lampshade.

[0011] With the above technical solution, the temperature value measured by the temperature measuring element located inside the transparent lampshade is more accurate.

[0012] Preferably, the temperature measuring element is located outside the transparent lampshade, and the temperature measuring element is disposed close to the transparent lampshade.

[0013] With the above technical solution, the temperature measuring element is located on the outside of the transparent lamp cover, making the production of the infrared heating lamp more convenient.

[0014] Preferably, the inner cavity of the transparent lampshade is a vacuum or filled with an inert gas.

[0015] The above technical solution ensures the normal operation of the infrared heating wire by filling it with inert gas. The infrared heating wire operates more stably in a vacuum environment.

[0016] Preferably, the infrared heating wire is a tungsten wire, a nickel-chromium wire, or graphene.

[0017] Through the above technical solutions, tungsten wire has the advantages of high resistivity and high strength. Nickel-chromium wire has the advantages of high resistivity and high strength at high temperatures. Graphene infrared heating wire has the advantage of high thermal conductivity.

[0018] Preferably, the temperature sensing element is a thermocouple, a resistance temperature detector (RTD), or a thermistor.

[0019] Through the above technical solutions, thermocouples, resistance temperature detectors (RTDs), and thermistors can all accurately detect the temperature inside the transparent lampshade. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered. Example

[0026] An infrared heating lamp with precise temperature control, such as Figure 1 , Figure 2 As shown, it includes a transparent lampshade 1, an infrared heating wire 2 disposed inside the transparent lampshade 1, a conductive lead 3 passing through the transparent lampshade 1, a temperature measuring element 4 fixedly disposed on the transparent lampshade 1, and a transmission wire 5 electrically connected to the temperature measuring element 4. The inner end of the conductive lead 3 is electrically connected to the infrared heating wire 2, and the conductive lead 3 is disposed through the lower end of the transparent lampshade 1.

[0027] The temperature sensing element 4 can be installed on the inside or outside of the transparent lampshade 1. When the temperature sensing element 4 is installed on the inside of the transparent lampshade 1, the transmission wire 5 can pass through the bottom or side of the transparent lampshade 1. When the temperature sensing element 4 is located on the outside of the transparent lampshade 1, the temperature sensing element 4 is set close to the transparent lampshade 1 to accurately detect the intensity of infrared radiation.

[0028] In this embodiment, the temperature sensing element 4 can be a thermocouple, a resistance temperature detector (RTD), or a thermistor.

[0029] To ensure the normal operation of the infrared heating wire 2, the inner cavity of the transparent lampshade 1 can be filled with inert gas, or the interior of the transparent lampshade 1 can be evacuated. When the inner cavity of the transparent lampshade 1 is evacuated, one of the key technologies is the non-matching seal between the transparent lampshade 1 and the conductive lead 3. Currently, the more representative non-matching seals mainly include: direct sealing of quartz and tungsten, transition glass sealing, brazing sealing, and molybdenum foil sealing.

[0030] The transparent lampshade 1 can be made of quartz glass or ordinary glass.

[0031] The infrared heating wire 2 can be made of tungsten wire, nickel-chromium wire or graphene. Example

[0032] The difference between Example 2 and Example 1 is that, as Figure 3 , Figure 4 As shown, a protective sleeve 6 is fitted on the outer side of the conductive lead 3, and the end of the protective sleeve 6 is pressed against the lower end of the transparent lampshade 1.

[0033] The lower end of the transparent lampshade 1 is recessed with a positioning groove 7, and the upper end of the protective soft sleeve 6 extends into the inner side of the positioning groove 7. A positioning protrusion 8 is integrally formed on the outer side of the upper end of the protective soft sleeve 6, and the positioning protrusion 8 is engaged with the inner side of the positioning groove 7. In this embodiment, the thickness of the positioning protrusion 8 is less than the depth of the positioning groove 7, and the upper end of the positioning protrusion 8 abuts against the upper end of the positioning groove 7.

[0034] During the transportation of the aforementioned infrared heating lamp, the protective sleeve 6 wraps around the conductive lead 3. This not only protects the conductive lead 3 from damage but also limits its bending, preventing breakage at the connection between the conductive lead 3 and the transparent lamp cover 1. When the infrared heating lamp needs to be installed, simply remove the protective sleeve 6 to expose the conductive lead 3.

[0035] A locking sleeve 9 is threadedly connected to the lower end of the positioning groove 7. The locking sleeve 9 is used to tighten the protective soft sleeve 6 or the conductive lead 3. The locking sleeve 9 includes a connecting ring 91 and locking blocks 92 evenly distributed around the circumference of the connecting ring 91. A T-shaped guide groove 10 is provided at the lower end of the connecting ring 91 opposite to the locking block 92. The T-shaped guide groove 10 is arranged radially along the connecting ring 91. A T-shaped guide block 11 is provided at the upper end of the locking block 92. The T-shaped guide block 11 is slidably connected in the T-shaped guide groove 10. A guide slope 12 is provided on the outer side of the locking block 92. When the T-shaped guide block 11 abuts against the outer end of the T-shaped guide groove 10, the upper end of the guide slope 12 engages with the outer wall of the connecting ring 91. When the guide slope 12 contacts the groove of the positioning groove 7, if the connecting ring 91 is tightened further, the transparent lampshade 1 can drive the locking block 92 to move toward the protective soft sleeve 6 or the conductive lead 3 through the guide slope 12, so as to tighten the protective soft sleeve 6 or the conductive lead 3.

[0036] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
