------17 / 04 / 2568------(OCR) OCR 10KL1. Portable electric mosquito repellent device with a built-in battery (1) with a rectangular structure made of engineering plastic box with ventilation holes for mounting and supporting the weight of various parts; charging or powering uses a USB port (2) which receives 5 volts DC power; a battery management system (BMS) (3) which monitors the voltage level of the lithium batteries (4) to keep them within the standard operating range so that the voltage levels inside each cell in the system are as close as possible. Inside the battery management system (BMS) (3) there is a display showing the operating status as a percentage while in use or charging; lithium batteries (4) are responsible for storing the power, in this device use 4 18650 models with a potential of 3.7 volts; a switch (5) to turn on or cut off the power; a heating plate (6) connected to the switch (5). The special feature is that the 4 18650 lithium batteries (4) each have a potential of 3.7 volts.7 volts with a USB port (2) receives 5 volts of DC power from an external source and sends it to the Battery Management System (BMS) (3) panel, which is responsible for maintaining the lithium battery (4) voltage level in the system as close as possible to the same value while in use or charging. Inside the Battery Management System (BMS) (3) panel, there is a display showing the operating or charging status of the lithium battery (4) as a percentage. When the lithium battery (4) is fully charged, the Battery Management System (BMS) (3) stops charging. When switch (5) is turned on, the Battery Management System (BMS) (3) receives 3.7 volts of power from the lithium battery (4), increases the voltage to 5 volts, and sends current through switch (5) to the heating plate (6), which heats up to a temperature of 65-70 degrees Celsius. ------------ ------02 / 12 / 2567------(OCR) OCR 10KL1. Portable electric mosquito repellent device. Consists of the device frame (1) with a rectangular structure made of engineering plastic box with ventilation holes for mounting and supporting the weight of various parts; charging or power charging uses a USB port (2) which will receive 5 volts DC power; battery management system (BMS) (3) which monitors the voltage level of the lithium batteries (4) to keep them within the standard operating range so that the voltage level inside each cell in the system is as close as possible. Inside the battery management system (BMS) (3) there is a display showing the operating status as a percentage while in use or charging; lithium batteries (4) which are responsible for storing the electrical charge, in this device use 4 18650 models with a potential of 3.7 volts; a switch (5) to turn on or cut off the power; a heating plate (6) connected to the switch (5). The special feature is that inside this device it uses 4 18650 lithium batteries (4) each with a potential of 3.7 volts.7 volts with a USB port (USB)(2) is used to receive 5 volts DC power from an external source and send it to the Battery Management System (BMS) (3) panel. Its function is to maintain the voltage level of the lithium battery (4) in the system to be as close as possible while in use or charging. Inside the Battery Management System (BMS) (3) panel, there is a display showing the operating or charging status of the lithium battery (4) as a percentage. When charging the lithium battery (4) is complete, the Battery Management System (BMS) (3) stops charging. When switch (5) is turned on, the Battery Management System (BMS) (3) receives 3.7 volts of power from the lithium battery (4), increasing the voltage to 5 volts, sending current through switch (5) to the heating plate (6), which heats up to a temperature of 65-70 degrees Celsius. If the heat accumulates more, it will damage the internal components, so the device's frame (1) must be designed with ventilation holes to reduce heat. It has the special characteristic of being able to charge or discharge the lithium battery (4). In this device, a 18650 model is chosen which has a voltage of 3.7 volts, 4 batteries and a battery management system (BMS) (3) that monitors the voltage level of the lithium batteries (4) to ensure that the voltage level inside each cell in the system is equal and as close as possible. Inside the battery management system (BMS) (3) there is a display showing the operating status as a percentage while in use or charging. When in use, current flows through a switch (5) to a heating plate (6). The housing of the device (1) has ventilation holes to reduce heat. ------------ ------16 / 08 / 2566------(OCR) 1. The portable electric mosquito repellent device is rechargeable and consists of a battery management system (BMS) panel (2), a USB port (3), a rechargeable lithium battery (3), an on / off switch (4), a heating tray (5), a compartment for mosquito repellent pads (6), and ventilation holes (7) around the rectangular device box. The device is designed for charging the battery using 5V DC power through the USB port (1) connected to the BMS panel (2). The system manages the charging of four 3.7V lithium batteries (3) connected in parallel to increase the battery capacity while maintaining the same voltage. Once charging is complete, the BMS (2) stops charging, and the charging cable can be disconnected. The on / off switch (4) is activated. The Battery Management System (BMS)X(2) manages the voltage from the lithium battery(3). 3.7 volts (Volt) is converted into a DC voltage level of Volts (Vol). When the current goes to the heating plate (5) which has a resistance of 15 Ohms (Ohm), it will heat up to about 60-70 degrees Celsius. There may be heat buildup inside the device box, causing damage to the battery management system (BMS) (2) and the lithium battery (3). Therefore, the device box must be designed with ventilation holes (7) around the device box to prevent excessive heat buildup inside the device. ------------ 1. A portable electric mosquito repellent device can store an electrical charge which contains... Equipment box (1) which contains an on / off switch (2) that controls the operation of the power connector (4). It is a 5-volt DC power receiver from an external power source, a heating pad on which the mosquito repellent pad is placed (3), which Inside the device box (1) there is a controller (5) which controls all of these functions located on the device box (1). Inside the device box (1) there is a control unit (5) which includes a USB (4) which has the function of Receiving DC power with a voltage of 5 volts, then the charging control circuit or BMS ( 6 ) controls the Charge the battery (7) Model 18650. The voltage is 3.7 volts and when the battery is charged The BMS (6) will cut off the charging to prevent overcharging and when you want to take the device out for use. To activate the switch (2), press the button. The BMS circuit (6) will control the power supply to the heating plate ( 3) It has a heating function that heats the mosquito repellent pad. The heating chamber has ventilation holes to prevent... Heat builds up inside the device. As mentioned above, portable electric mosquito repellent devices store electrical charge. The device is powered by a 3.7-volt DC battery, allowing it to be carried and used anywhere. Indoors and outdoors, the battery can charge for the duration it is stored.
