With the advancement of modern technology, people’s reliance on mobile phones has become heavier and heavier. Because users use mobile phones frequently, they need to charge frequently, and most modern users have poor charging habits for mobile phones. I often forget that I am charging after I plug in the charging cable. I don’t think of unplugging the mobile phone charging cable until I need it. This causes the battery to overheat and even catch fire and explode in severe cases, which seriously threatens the life of users. There are countless accidents caused by fire and explosion of charging, especially when people charge their mobile phones at night, they often put their mobile phones and chargers on the bedside, and fire and explosion can cause more harm to the human body.

At present, the common fireproof charging boxes for mobile phones on the market are mostly made of fire-resistant and explosion-proof materials. Although they can prevent the fire from expanding, they still cannot be controlled at the initial stage of the fire to reduce the incidence of fire. Moreover, the charging box If the mobile phone is continuously charged, there is a risk of electric shock. When an explosion occurs, fragments are likely to fly out, posing a serious safety hazard.

Accordingly, how to provide a charging protector capable of charging the mobile phone in the mobile phone and achieving fire and explosion protection when the mobile phone is burned or exploded is a problem that the industry urgently wants to solve.

In the explosion-proof heat-dissipating charging protector, a cooling device is further provided in the box body.

In the explosion-proof heat-dissipating charging protector, the box body is further provided with a temperature sensing device, which is electrically connected to the circuit. When the temperature sensing device detects that the internal temperature of the box body is higher than the preset value, the circuit stops powered by.

In the explosion-proof heat-dissipating charging protector, the box body is further provided with a flame detector, which is electrically connected to a circuit, and when the flame detector detects that there is a fire inside the box body, the power supply of the circuit is stopped.

In the explosion-proof heat-dissipating charging protector, the cover has a perspective part, and the perspective part is made of explosion-proof and heat-resistant material.

The explosion-proof heat-dissipating charging protector further includes an anti-vibration part, and the anti-vibration part is arranged along the periphery of the box body and the cover body.

The new type of explosion-proof heat-dissipating charging protector, because the inside of the box contains a heat insulation layer and a fireproof layer, the insulation layer is filled with inert gas, and because the inert gas has the characteristics of non-flammability and non-combustion, it can block the internal temperature and make the outside of the box body It will not be hot, and the fire-resistant layer is made of fire-resistant and flame-retardant materials, which can prevent the fire from growing. Furthermore, there is a fire-fighting unit on the box body, which can detect the occurrence of fire in the event of a fire and explosion, and activate the fire-fighting piece to accommodate The trough implements fire fighting actions to extinguish fires.

The aforementioned and other technical content, features and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiment with reference to the drawings.

When the temperature of the electronic device 30 is too high, the thermal energy of the electronic device 30 can be transferred to the cooling medium in the cooling device 50 to reduce the temperature. The temperature of the box body 10 effectively protects the electronic device 30 and avoids the occurrence of abnormal temperature rise due to the electronic device 30 during charging. The cooling medium includes at least one pure water, one ethylene glycol, one diethylene glycol, One or a combination of monopropylene glycol.

The second embodiment is that the cooling device 50 is a cold chip, the cold chip is embedded in the accommodating groove 105, the cold chip has a cold surface (not shown) and a hot surface (not shown), the The hot surface is attached to a heat dissipation element (not shown).

At this time, the pressure of the steel cylinder has been relieved, and the fire It is not easy to expand, and the metal layer 107 resists heat, so that the fire fighting element 401 has a certain degree of protection. On the contrary, when the fuse 403 is not melted, the gas will be locked inside the pipeline 407 and the fire fighting element 401. In addition, when the cover body 20 is placed on the box body 10, the explosion-proof heat-dissipating charging protector 1 of the present invention is closed, and when the internal carbon dioxide concentration reaches a certain level, the fire extinguishing potential can be perfectly eliminated.

According to the design of this creation, the fire-fighting component 401 steel cylinder of the explosion-proof heat-dissipating charging protector 1 of the present invention is a small high-pressure steel cylinder. The gas is not leaked through the sealing of the fuse 403. When the accommodating tank 105 catches fire, it will The fuse 403 is melted so that the fire extinguishing gas can be sprayed into the containing tank 105 to extinguish the fire. The installation method of the high-pressure steel cylinder is: when the high-pressure steel cylinder is installed, the fuse 403 must be sealed first, then the pipeline 407 should be rotated upward, and then the high-pressure steel cylinder should be placed on the joint of the pipeline 407 and tightened, and then The pipeline 407 and the high-pressure steel cylinder rotate together down to the box body 10, and finally the high-pressure steel cylinder is buckled in the slot; and the fuse 403 is installed in the following way: a through hole (not shown) is provided on the fireproof layer 103 ), the one end opening of the pipeline 407 is passed through the through hole into the containing groove 105, and then the fuse 403 is fastened to close the one end opening of the pipeline 407.

For continuation, please refer to Figure 4. The second embodiment is that the fire-fighting component 401 is filled with a coolant or a metal fire extinguishing agent, and is set in the accommodating groove 105. When the box body 10 is inside When the temperature is too high, the fuse 403 (that is, the outer shell of the fire fighting component) covering the fire fighting component 401 melts, and the coolant in the fire fighting component 401 flows out to perform a fire fighting action. Wherein, the cooling liquid contains at least one of pure water, monoethylene glycol, diethylene glycol, and propylene glycol or a combination thereof, and the fire extinguishing agent used for the metal fire is most preferably sodium chloride dry powder. Due to the non-conductive nature of the cooling liquid, even if the power supply of the electronic device 30 in the box body 10 is continuously charged, there is no danger of electric shock when it touches the cooling liquid.
