When the fan 4 is forcibly dissipating ventilation, the wind and heat flow out of the heat sink 2 are outward axial winds to avoid dust into the housing 1 to further reduce dust in the power adapter main body 41 in the housing 1. The probability of short circuit of electronic components.
[0035] As an embodiment of the present invention, such as image 3 As shown, a control cartridge 5 is provided on the wire of the heat storage fan 4 connected to the heat dissipation fan 4, and the upper left end of the control cartridge 5 is fixedly coupled with a third metal sheet 51, and the third metal sheet 51 fixedly connected to the wire. Further, the third metal sheet 51 fixedly connected wire through the left end surface of the control cartridge 5 and fixed to the battery 39, the third metal sheet 51, the right end surface is bonded to the fourth metal sheet 52, the fourth metal sheet 52 In the control cartridge 5, the connection is slid, and the fourth metal sheet 52 is fixedly connected to the wire, and the wires upper end of the fourth metal sheet 52 penetrate through the rectangular groove 53 and the heat dissipation fan 4 is fixed, the rectangular groove 53 The upper end of the control cartridge 5 is opened, and the fourth metal sheet 52 is fixed to the upper side center, and the slider 54 is rotated through the right side of the right side of the control cartridge 5 and slides the connection, and the slider 54 extends. One end of the control cartridge 5 is fixed to the ferromagnetic block 55, and the slider 54 extends to one end sleeve of the control cartridge 5 is provided with a support spring 56.
[0036] When the device falls into the water due to human misoperation, the waterproof mechanism 3 operates, and the battery 39 supplies the electromagnet 38 to generate a magnetic pole attraction, and the electromagnet 38 sucks the ferromagnetic block 55 and causes the iron magnetic block. 55 moves horizontally toward the direction of the electromagnet 38, that is, the fourth metal sheet 52 fixed to the wire through the slider 54 is moved to the right level, thereby leaving the third metal sheet 51, at this time, the third metal sheet 51 and the first Since the four metal sheet 52 causes the battery 39 to supply the battery 39 to the heat dissipation fan 4, the heat dissipation fan 4 is stopped, thereby reducing energy loss.
[0037] As an embodiment of the present invention, such as figure 2 As shown, the lower end surface of the power source adapter body 41 separates the equal spacing with a set of support holes 6, and the lower end side wall of the support cartridge 6 is formed through the support rod 61 and slides, the support rod 61 penetrates into the support. 6 One end is fixedly connected to a damper spring 62, and the lower end of the support rod 61 is fixed to the bottom of the inner surface of the housing 1.
[0038] When operating, the device is inevitable when the device falls into the water in the process of falling into the water and the impairment of the device in the process of moving the device, and the device is inevitable, the support, the support rod 61 and the damper The interaction force between the spring 62 can buffer such vibration to protect the power adapter main body 41 in the housing 1.
[0039] Working principle: When the device is used, since the device falls into the water, the two groups in the waterproof groove 31 have a rapid expansion of the water expansion rubber stopper 32, and the two groups have a water expansion rubber stopper strip. 32 The rapid expansion of water absorbing is in contact with the phase together and sealed, thereby avoiding the water into the housing 1 to short the electronic components in the housing 1, and the waterproof groove 31 in the lower end of the surface of the heat dissipation port 2 is water expansion rubber stopper strip. 32 expansion and the first metal sheet 391, the second metal sheet 392, due to the characteristics of the water, the first metal sheet 391, the second metal sheet 392, and the water expansion rubber stopper strip 32 are in metallogenous rubber The water absorbed by the water strip 32 is connected, at which time the electromagnet 38, the battery 39, the first metal sheet 391, the second metal sheet 392, and several wires together form a closed path, at which time the battery 39 is energized to electromagnet 38 The iron 38 has magnetic properties to suck the ferrous plate 35 into the water tank 37, that is, the ferrule plate 34 fixed to the ferrous plate 35 extends into the water tank 37, and can be fill in the water expansion rubber stopper 32 expands. After returning the water retirement water tank 37, the gap between the water expansion rubber stopper strip 32 is met, thereby further improving the sealing effect such that the apparatus has significant waterproofability, thereby better protecting the device;
[0040] The battery 39 operates from the heat dissipation fan 4 to operate the heat dissipation fan 4, and the heat dissipation fan 4 is maintained to force the power adapter main body 41 in the housing 1 to force heat ventilation, the wind and heat, and flow through the heat sink 2, the heat dissipation port 2 The setting of the filter plate 7 causes the external dust, the solid particles, and the like, and when the heat dissipation fan 4 is forcibly dissipating, the wind and heat flow out of the heat sink 2, and the axial wind that can also avoid dust into the shell. In the body 1, the probability of short-circuiting the electronic component in the power adapter main body 41 in the housing 1 is reduced;
[0041] When the device falls into the water due to human misoperation, the waterproof mechanism 3 operates, and the battery 39 supplies the electromagnet 38 to generate a magnetic pole attraction, and the electromagnet 38 sucks the iron magnetic block 55 and causes the iron magnetic block 55 toward the iron magnetic block 55. The direction horizontal movement of the electromagnet 38, that is, the ferrous block 55 is moved to the right level by the fourth metal sheet 52 fixed to the slider 54, thereby leaving the third metal sheet 51, at which time the third metal sheet 51 and the fourth metal sheet 52 Since the battery 39 is difficult to supply the battery 39 to the heat dissipation fan 4, the heat dissipation fan 4 is stopped, thereby avoiding the inlet waterproof mechanism 3 to operate the housing 1 in the case, thereby reducing energy loss.
