[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] Embodiment 1:

[0026] like Figure 1-Figure 3 As shown, the present embodiment provides a safety oil lamp 10 (hereinafter referred to as the oil lamp 10), including a wick 100, a transparent wind shield 200, a fire extinguishing device 300, a plurality of temperature detectors 400, and a control unit 500. The wick 100 is provided with a combustion portion 110 at the top in the vertical direction. The combustion portion 110 is stained with fuel. The wind shield 200 is provided on the periphery of the combustion portion 110. The temperature detector 400 is located at the lower end of the combustion portion 110, and is used to detect the temperature of the lower end of the combustion portion 110. The control unit 500 is communicatively connected to the fire extinguishing device 300 and the temperature detector 400. When the average value of the temperatures detected by the plurality of temperature detectors 400 is greater than a preset temperature, the control unit 500 controls the fire extinguishing device 300 to extinguish the flame of the combustion portion 110.

[0027] It can be seen that in the above-mentioned safety oil lamp 10, the transparent wind shield 200 not only does not affect the user's viewing of the burning state of the oil lamp 10, but also can protect the flame, prevent the external airflow from blowing the flame during the flow process, and not only prevent the flame and fuel from being blown onto the combustible material, but also improve the stability of the flame combustion. In addition, when the temperature detector 400 detects that the temperature at the lower end of the combustion part 110 is higher than the preset temperature, the control unit 500 can control the fire extinguishing device 300 to extinguish the flame, which can avoid the flame burning too vigorously inside the wind shield 200, thereby causing the wind shield 200 to self-ignite, etc., which is conducive to further improving the safety of the oil lamp 10 during use.

[0028] It should be noted that the wind shield 200 can prevent the flame and lamp oil from splashing onto other flammable materials, and the temperature detector 400 can prevent the flame from excessively burning inside the wind shield 200. The two cooperate with each other to comprehensively improve the fire prevention performance and safety of the oil lamp 10.

[0029] In addition, in order to prevent the wind shield 200 from being ignited by flames, the wind shield 200 should be made of a high temperature resistant transparent material.

[0030] Embodiment 2:

[0031] This embodiment provides a safety oil lamp. The safety oil lamp provided in this embodiment is optimized based on the embodiment 1. Figure 1 As shown, in this embodiment, the upper opening of the wind shield 200 is circular and has a diameter of not less than 18 mm, which is conducive to preventing the air in the wind shield 200 from being sealed due to the opening of the wind shield 200 being too small, causing the flame to automatically extinguish after burning for a period of time. In addition, the height H of the wind shield 200 in the vertical direction is between 20 mm and 25 mm.

[0032] In one embodiment, Figure 3 As shown, there are three temperature detectors 400, which are arranged at intervals on the outer periphery of the lower end of the combustion part 110. The three temperature detectors 400 simultaneously detect the temperature of the lower end of the combustion part 110 and obtain three temperature values. The control unit 500 calculates the three values ​​and takes the average value of the three values ​​as the detected temperature. When the detected temperature is greater than the preset temperature, the control unit 500 further controls the fire extinguishing device 300 to extinguish the flame of the combustion part 110.

[0033] It should be understood that, as an optional embodiment, the number of temperature detectors 400 can also be designed to be 4. The number of temperature detectors 400 is 4. The 4 temperature detectors 400 simultaneously detect the temperature of the lower end of the combustion part 110 and obtain 4 temperature values. The control unit 500 calculates the 4 values ​​and takes the average value of the 4 values ​​as the detected temperature. When the detected temperature is greater than the preset temperature, the control unit 500 further controls the fire extinguishing device 300 to extinguish the flame of the combustion part 110.

[0034] Therefore, the number of temperature detectors 400 can be set according to actual needs and should not be construed as a limitation to the present application.

[0035] It should be noted that, during the normal combustion of the combustion part 110, the temperature of the lower end of the combustion part 110 generally does not exceed 120°C. Therefore, when the temperature of the lower end of the combustion part 110 exceeds 120°C, timely use of the fire extinguishing device 300 to extinguish the flame at the combustion part 110 can further improve the fire prevention effect. Therefore, in this embodiment, the preset temperature is 120°C.

[0036] It is understood that, as a preferred embodiment, the preset temperature in this embodiment is 120°C, and as an optional embodiment, the preset temperature is set to be slightly greater than 120°C or slightly less than 120°C, which will not affect the implementation effect of this embodiment. Therefore, it should not be understood as limiting the scope of protection of this application.

[0037] In addition, as a preferred embodiment, the temperature detector 400 in this embodiment is a negative temperature coefficient thermistor. Therefore, the resistance value of the temperature detector 400 decreases as the temperature near it increases. When the temperature at the lower end of the combustion part 110 exceeds 120°C, the resistance of the temperature detector 400 decreases accordingly. As an optional embodiment, the temperature detector 400 in this embodiment can also be a temperature detector of other forms, which is based on the purpose of achieving temperature detection, and will not be described in detail or limited here.

[0038] In one embodiment, Figure 1 As shown, the oil lamp 10 further includes a lamp holder 600. The wick 100 is inserted into the lamp holder 600, and the burning part 110 is located above the lamp holder 600. The lamp holder 600 is also provided with a position detector 610 for detecting the inclination angle of the lamp holder 600 relative to the horizontal plane. The position detector 610 is communicatively connected to the control unit 500 and can transmit position information to the control unit 500. When the inclination angle detected by the position detector 610 is greater than 10°, the control unit 500 controls the fire extinguishing device 300 to extinguish the flame at the burning part 110.

[0039] It can be seen that the position detector 610 cooperates with the control unit 500 and the fire extinguishing device 300 to promptly extinguish the flame at the burning part 110 when the oil lamp 10 is tilted more than 10°, thereby preventing the flame at the burning part 110 from splashing out from the opening of the wind shield 200 when the oil lamp 10 is subjected to external impact and causing problems such as fire, which is beneficial to further improve the safety of the oil lamp 10.

[0040] Specifically, in this embodiment, as a preferred implementation, the position detector 610 is a level meter. As an optional implementation, the position detector 610 can also be other forms of sensors, which can detect the tilt angle of the lamp holder 600 relative to the horizontal plane, and are not specifically limited here.

[0041] As a further description of this embodiment, the fire extinguishing device 300 in this embodiment can be designed into different forms according to actual needs. As a preferred embodiment, the fire extinguishing device 300 can be designed as a flame retardant sheet. When the position detector 610 cooperates with the control unit 500 and the fire extinguishing device 300, when the oil lamp 10 is tilted more than 10°, the control unit 500 controls the flame retardant sheet of the fire extinguishing device 300 to extinguish the fire by blocking oxygen; as an optional embodiment, the fire extinguishing device 300 can be designed as other forms of fire extinguishing devices, and can also extinguish the fire by blocking the burning material. It will not be described in detail or limited here.

[0042] Embodiment 3:

[0043] This embodiment provides a safety oil lamp, which is optimized based on the first or second embodiment. Figure 1 As shown, in this embodiment, the oil lamp 10 is built with a power supply 700. The power supply 700 is electrically connected to the control unit 500, the temperature detector 400, the fire extinguishing device 300, and the position detector 610. Therefore, when the oil lamp 10 has no external power supply, the combustion state and position state of the oil lamp 10 can still be monitored. When the combustion state of the oil lamp 10 is abnormal (the temperature at the lower end of the combustion part 110 is greater than 120°C) and / or the position state is abnormal (the inclination angle of the lamp holder 600 exceeds 10°), the control unit 500 can automatically control the fire extinguishing device 300 to extinguish the flame at the combustion part 110, thereby realizing automatic fire extinguishing of the oil lamp 10.

[0044] In one embodiment, Figure 1 As shown, the oil lamp 10 further includes an oil pot 800. The oil pot 800 is located at the bottom of the lamp holder 600 and contains ghee, and is used to supply oil to the combustion part 110. The bottom end of the wick 100 is inserted into the oil pot 800, and the combustion part 110 at the upper end extends out of the lamp holder 600.

[0045] Furthermore, the oil lamp 10 further includes a lampshade 900. The lampshade 900 is movably connected to the upper end of the lamp holder 600, and can be folded or unfolded relative to the burning part 110 to simulate the posture of a blooming lotus, which is conducive to making the oil lamp 10 more beautiful.
