Mobile power supply + warm hand treasure scheme
Mobile power supply + warm hand treasure scheme
This circuit integrates high current MOS tubes, supports 2A charging and 2A discharging, and automatically identifies the insertion of discharge load. It is widely used in warm hand treasure, warm foot treasure, warm palace treasure, warm neck treasure, warm water bag, milk / water insulation and other products.
The board is equipped with a high-speed MCU to quickly identify the ambient temperature with the temperature sensor to effectively empty the MOS tube to heat the heating plate. In different use environments, MCU can set multiple heating temperatures to adapt.
This MCU has low standby power consumption and is easy to apply battery products.
The rechargeable warm hand treasure with mobile power supply function is developed through single chip microcomputer chip. It has become one of the necessary items in winter. The single chip microcomputer microcontroller sends program signals to the heating plate for heating work, which makes the cold winter warmer. When selecting the charging hand warmer, we consider the following issues. Today, chipsourcetek of siyuante technology introduces some main precautions for warm hand treasure charging.
1、 Advantages and disadvantages of warm hand treasure
1. From my point of view: ordinary rechargeable hand warmer uses lithium battery function, which has three advantages: large capacity, more environmental protection, recyclable, and can be stored twice at room temperature after charging for 3-4 hours. Of course, depending on the model, different lithium battery models will consume different electricity.
2. From the perspective of health: electric heating is beneficial to health. Generally, it can accelerate blood circulation and metabolism. There is a confident ceramic heater inside, without electromagnetic radiation, which is very suitable for patients with arthritis and rheumatism in winter.
3. From the appearance: the general charging warm hand treasure is small and lovely, and can also be equipped with different coats. It is considered to be one of the winter girls who sell lovely cultural relics and is widely loved by girls.
4. From the perspective of ease of use: USB charging function can be used to charge various digital products (such as charging treasure), which is very convenient at home, work and go out.
2、 Classification of warm hand treasure
1. Hot water heating: compared with the traditional hot water bottle, the electric water bottle saves the trouble of adding water. Plug in the power supply for 10 minutes to generate heat.
2. Fever through chemical reaction: add chemicals in the body to generate heat through electricity, which is the type of early warm babies on the market.
3. Heating with lithium battery: the new rechargeable hand warmer is more convenient. It generates heat through the internal heating plate, which is more environmentally friendly for recycling. Small size will emit a lot of heat and be more durable.
3、 How to use the charging warm hand treasure correctly:
1. After the power is turned on, the charging starts when the indicator light is on. If the indicator light is not on, please unplug the power supply and check whether there is a problem. When the temperature reaches a certain level, the indicator light will go out. At this time, unplug the power supply as soon as possible and do not charge for too long.
2. When charging, keep away from the hand warmer. Try to avoid serious accidents caused by accidents. However, please do not leave home when charging. In case of an accident, you can deal with it in time.
3. Daily care: due to the internal electrical principle, it is usually impossible to clean directly. If the shell is ceramic, wipe it with a dry cloth. If there are substances that are difficult to clean or fade, wipe them with some detergent first, and then wipe them with a dry towel.
4. Precautions in use: there are many warm handbags on the market. You can choose one for the rechargeable hand warmer. This not only isolates heat and avoids overheating, but also ensures the appearance of the rechargeable hand warmer.
Now the technology is becoming more and more perfect. It can well control the fault events of warm hand treasure. Among them, the single chip microcomputer chip is indispensable. It controls the rated temperature of warm hand treasure through program to prevent overheating. However, users still need to carefully read the user manual and maintain the product according to the instructions to avoid accidents.
The above is the relevant knowledge about the development of mobile power supply + warm hand treasure single chip microcomputer scheme.
