Description

Technical Field

[0001] This utility model relates to the field of candle lamp technology, specifically a candle lamp controller with a safety protection structure. Background Technology

[0002] Traditional candles consist of a candle body and a wick, with the flame produced by the burning candle wax providing light. However, incomplete burning of the wick can easily lead to smoke and carbon buildup, and the wick is also prone to tipping over during combustion, causing it to go out or even ignite. In modern daily life, fluorescent lights, LED lights, and table lamps have replaced candles as the mainstream lighting fixtures. However, there is still a market demand for candles to create ambiance or for nostalgia, which led to the creation of candle lamps. But since candle lamps are often used for extended periods, their temperature gradually accumulates and rises. When the temperature becomes too high, the outer shell of the candle lamp may deform or melt, which can easily lead to fire or damage to the candle lamp, making it relatively unsafe to use. Utility Model Content

[0003] The purpose of this invention is to provide a candle lamp controller with a safety protection structure to solve the safety problems mentioned in the background art, such as the risk of melting, deformation, and fire caused by the temperature rise of candle lamps after prolonged use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a candle lamp controller with a safety protection structure, comprising a housing, the housing being a cylindrical barrel structure, and a diffuser being fitted onto the outer surface of the housing, the diffuser being inserted into the outer surface of the housing, a bottom shell being fitted onto the outer surface of the housing away from the diffuser, a control motherboard being fitted onto the inside of the housing, the control motherboard being attached to the side surface of the housing, heat dissipation fins being fitted onto the inside of the housing, and a thermistor being placed on the inner side of the heat dissipation fins and connected to the control motherboard.

[0005] Preferably, a heat dissipation silicone pad is attached to the outer surface of the heat dissipation fins, and the heat dissipation silicone pad is in close contact with the outer surface of the control motherboard. A heat dissipation hole is fixedly opened on the outer surface of the housing near the diffuser, and the height of the heat dissipation hole is the same as the height of the heat dissipation fins.

[0006] By adopting the above technical solution, the heat generated by the control motherboard during operation can be conducted to the heat dissipation fins through the heat dissipation silicone pad. The heat dissipation fins increase the heat dissipation area and improve the cooling speed. At the same time, the heat dissipation holes allow air convection to further reduce the heat dissipation speed of the heat dissipation fins, thereby reducing the risk of melting and burning caused by excessive heat concentration on the LED light circuit board and control motherboard, which could damage the casing or diffuser.

[0007] Preferably, a thermally conductive silicone pad is snapped onto the outer surface of the heat dissipation fins, and the outer surface of the thermally conductive silicone pad is in close contact with the outer surface of the heat dissipation fins. The thermally conductive silicone pad and the thermistor are connected by plug-in connection, and the thermally conductive silicone pad is in contact with the outer surface of the diffuser.

[0008] By adopting the above technical solution, the efficiency of heat dissipation fins in absorbing the temperature of LED circuit board can be further improved through the thermal conductive silicone pad. At the same time, it can provide effective support for LED circuit board and reduce the positional displacement of LED circuit board and thermistor caused by drop and vibration.

[0009] Preferably, an LED circuit board is installed inside the diffuser, and a metal spring is fixedly installed on the outer surface of the control board. The metal spring is inserted into the LED circuit board, and the outer surface of the LED circuit board is in contact with the outer surface of the thermally conductive silicone pad.

[0010] By using the above technical solution, the control motherboard and LED circuit board can be easily and quickly assembled and disassembled by inserting and fixing the metal spring contact with the LED circuit board, which facilitates disassembly and replacement in case of subsequent failure.

[0011] Preferably, elastic fastening pieces are fixedly installed on the outer surfaces of both ends of the bottom shell, and the elastic fastening pieces are engaged with the outer shell, and the elastic fastening pieces penetrate the outer surface of the outer shell.

[0012] Using the above technical solution, the outer shell and the bottom shell can be easily assembled together by means of elastic fastening tabs. The battery box, control board and heat sink can be squeezed and fixed by the engagement of the outer shell and the insert metal spring. At the same time, when disassembly and maintenance are required, tools can be inserted into the connection between the outer shell and the elastic fastening tabs to disassemble, which greatly reduces the use of screws and reduces the difficulty of installation and disassembly.

[0013] Preferably, a battery box is snapped into the inside of the bottom shell, and the other end of the battery box is attached to the outer surface of the control motherboard. A lithium battery is inserted into the inside of the battery box, and a compartment door is snapped into the outer surface of the bottom shell and fixed to the bottom shell with screws.

[0014] Using the above technical solution, the compartment door can be separated from the bottom shell by removing the screws, allowing the lithium battery to be replaced quickly and used continuously without charging.

[0015] Preferably, a switch is snapped onto the outer surface of the bottom shell, and the switch is located inside the bottom shell. The switch is connected to the battery box and the control motherboard respectively.

[0016] Using the above technical solution, the connection and disconnection of the circuit between the battery box and the control motherboard can be controlled by a switch. At the same time, when the switch is damaged, it can be easily and quickly disassembled and replaced. In addition, the position of the switch on the bottom shell will not affect the placement of the candle lamp.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the candle lamp controller equipped with a safety protection structure:

[0018] 1. After the candle lamp has been used for a period of time, the control board and LED circuit board will generate heat. At this time, the heat will be conducted to the heat dissipation silicone pad and the thermal conductive silicone pad. The operating temperature of the candle lamp can be monitored by the thermistor. When the temperature exceeds the limit value of the thermistor, the LED circuit board can automatically cut off the power to reduce the temperature rise. This reduces the risk of melting or burning of the shell, diffuser and other components due to prolonged use, greatly improving the safety of the candle lamp and extending its service life.

[0019] 2. After the candle light is turned on, the thermal pads will absorb the heat emitted by the control board and the LED circuit board, allowing the control board to operate stably at a suitable temperature. The thermal pads also ensure the stability of the connection between the LED circuit board and the metal contact springs. The thermal pads absorb heat while improving the stability of the LED circuit board. In conjunction with the use of heat dissipation holes, heat can be carried away from the heat sink more quickly, improving the stability of the control board and the lifespan of the LED circuit board.

[0020] 3. The bottom shell can be easily fixed inside the outer shell by the snap-fit ​​tabs, while the battery box, control board, thermal pad, heat dissipation fins and diffuser can be firmly squeezed and fixed inside the outer shell without the need for too many screws, which greatly improves the convenience of installation, disassembly and maintenance.

Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a candle lamp controller with a safety protection structure, including a shell 1, which is a cylindrical barrel structure. A diffuser 2 is fitted onto the outer surface of the shell 1, and the diffuser 2 is inserted into the outer surface of the shell 1. A bottom shell 11 is fitted onto the outer surface of the shell 1 away from the diffuser 2. A control main board 3 is fitted onto the inside of the shell 1, and the control main board 3 is attached to the side surface of the shell 1. A heat sink fin 4 is fitted onto the inside of the shell 1, and a thermistor 8 is placed on the inner side of the heat sink fin 4. Resistor 8 is connected to control motherboard 3. A thermal pad 6 is attached to the outer surface of heat sink 4, and the thermal pad 6 is in close contact with the outer surface of control motherboard 3. A thermal pad 7 is snapped onto the outer surface of heat sink 4, and the outer surface of thermal pad 7 is in close contact with the outer surface of heat sink 4. Thermal pad 7 and thermistor 8 are plugged into each other. Thermal pad 7 is attached to the outer surface of diffuser 2. A heat dissipation hole 5 is fixedly opened on the outer surface of the outer shell 1 near diffuser 2, and the height of heat dissipation hole 5 is the same as the height of heat sink 4.

[0030] Firstly, when using the candle lamp, simply turn on switch 12 to connect the battery box 14 to the control board 3, enabling the control board 3 to power on and supply power to the LED circuit board 9. After prolonged use, the temperature of the control board 3 and the LED circuit board 9 will rise. The generated heat will be conducted to the heat dissipation fins 4 through the heat dissipation silicone pads 6 and 7. Air can also enter the outer shell 1 through the heat dissipation holes 5 to remove the heat from the heat dissipation fins 4, allowing the control board 3 to operate at a suitable temperature and reducing the heat generated by the LED circuit board 9. At the same time, the operating temperature is monitored by the thermistor 8, and the power can be cut off when the temperature exceeds the value of the thermistor 8 to reduce the temperature. This prevents the outer shell 1 and the diffuser 2 from melting or softening due to high temperature, reducing the deformation or burning of the outer shell 1 and the diffuser 2 caused by temperature, greatly improving the lifespan and safety of the candle lamp.

[0031] An LED light circuit board 9 is installed inside the diffuser 2. A metal spring 10 is fixedly installed on the outer surface of the control board 3, and the metal spring 10 is inserted into the LED light circuit board 9. The outer surface of the LED light circuit board 9 is in contact with the outer surface of the thermally conductive silicone pad 7.

[0032] Furthermore, during assembly, the LED light circuit board 9 and the plug-in metal spring 10 can be easily and firmly connected and fixed to the control motherboard 3, greatly improving the installation speed of the control motherboard 3 and the LED light circuit board 9, and enhancing the ease of maintenance and installation of the candle lamp.

[0033] Elastic fastening pieces 16 are fixedly installed on the outer surfaces of both ends of the bottom shell 11, and the elastic fastening pieces 16 are engaged with the outer shell 1. The elastic fastening pieces 16 penetrate the outer surface of the outer shell 1. A battery box 14 is snapped into the inside of the bottom shell 11, and the other end of the battery box 14 is attached to the outer surface of the control main board 3. A lithium battery 15 is inserted into the inside of the battery box 14. A compartment door 13 is snapped into the outer surface of the bottom shell 11, and the compartment door 13 is fixed to the bottom shell 11 with screws. A switch 12 is snapped into the outer surface of the bottom shell 11, and the switch 12 is located inside the bottom shell 11. The switch 12 is connected to the battery box 14 and the control main board 3 respectively.

[0034] Secondly, when assembling the candle lamp, simply assemble the diffuser 2, control board 3, heat sink 4, heat dissipation hole 5, heat dissipation silicone pad 6, thermal conductive silicone pad 7, thermistor 8, and LED circuit board 9 in sequence. Then, insert the battery box 14 and bottom shell 11 into the outer shell 1. The bottom shell 11 is fixed inside the outer shell 1 by the elastic fastening piece 16 engaging with the outer shell 1. The bottom shell 11 is pressed and fixed into the outer shell 1, allowing the components inside the candle lamp to be spliced ​​together by compression during assembly. The door 13 can be removed from the bottom shell 11 by loosening the screws, allowing for quick replacement of the lithium battery 15 without charging. This allows for quick and convenient assembly of the candle lamp without the need for excessive screws, greatly improving the ease of assembly and maintenance.

[0035] Working Principle: During use, simply switch 12 connects the circuit between the battery box 14 and the control board 3, allowing the lithium battery 15 to power the control board 3. The control board 3 then powers the LED circuit board 9, and the light emitted by the LED circuit board 9 is softened by the diffuser 2 to prevent glare. After prolonged use, the heat generated by the control board 3 and the LED circuit board 9 is conducted to the heat sink fins 4 through the heat dissipation silicone pads 6 and 7, increasing the heat dissipation area and efficiency. The heat dissipation holes 5 further enhance heat dissipation efficiency. Simultaneously, the thermistor 8 monitors the candle's operating temperature, preventing overheating that could melt or damage the outer casing 1 and diffuser 2. This improves the stability of the control board 3 and extends the lifespan of the LED circuit board 9, significantly enhancing the stability and safety of the candle and reducing damage, melting, and combustion caused by excessively high temperatures during prolonged operation.
