Intelligent physical doll vocalization and heating standards

There are many smart physical dolls on the market, some of which can make sounds and heat up, but the problem arises. If they are hot, electricity is needed, so the safety of electricity use is involved. Now there are two types of dolls on the market, one is 220V. AC heating, one is 48V DC heating. Which of the two methods is more secure?

 

220V AC heating doll, commonly used in silicone solid dolls,

Working principle, 220V direct plug-in, without any transformation, power 500W, resistance around 200 ohms, current up to 2.1A, such a working environment is a dangerous current environment for people, exceeding the human body safety voltage of 36V , The degree of harm of electric shock to the human body mainly depends on the size of the current passing through the human body and the length of the power-on time. The greater the current intensity, the greater the fatal danger; the longer the duration, the greater the possibility of death.

 

As a close-fitting toy, you must take good care of the doll, and you would like to enjoy it anytime, anywhere.

And if it is plugged in for a long time, the doll will continue to heat up, which will eventually cause a huge damage to the doll. Injury principle: The silicone solid doll is filled with two materials. When heated, the air inside will expand and cause the doll to deform.

 

48V DC heating doll, commonly used with TPE physical doll, working principle, 48V DC power supply,

Such a voltage, which is equivalent to the voltage of an electric vehicle, is a recognized safe voltage. Because of the direct current, the harm to the human body is extremely low, and the heating of the TPE is very uniform. There is no air in it, so heating will not expand the air inside, and there will be no bubbles.

 

It can be said that as your personal toy, it is qualified, and it can be heated and used anytime and anywhere. This low-voltage working mode will also greatly reduce the damage to the doll.
