Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a portable reinforced computer, including a metal chassis 1 and a small water tank 2 fixed above the metal chassis 1, with cold water stored inside. Assembly covers 3 are fixed on both sides of the metal chassis 1. Installation grooves 4 are penetrated through both assembly covers 3. Dust-proof nets 5 are fixed on the inner walls of the two installation grooves 4. The dust-proof nets 5 are used to prevent external dust from entering the metal chassis 1, thereby protecting the components in the metal chassis 1. An air-blowing mechanism 6 is arranged inside the metal chassis 1. The air-blowing mechanism 6 is used to discharge the heat in the metal chassis 1 to achieve heat dissipation and ventilation. Support and reinforcement rods 7 are fixed at the inner wall corners of the metal chassis 1. The support and reinforcement rods 7 are used to reinforce the metal chassis 1. The whole device forms a triangular design between the support and reinforcement rods 7 and the inner wall of the metal chassis 1, thereby improving the compressive resistance of the metal chassis 1. Mobile universal wheels 8 are installed at the four corners of the bottom of the metal chassis 1. Through the setting of the mobile universal wheels 8, it is convenient to push the whole metal chassis 1, making it more convenient to use.

[0025] In the embodiment of the present invention, the blowing mechanism 6 includes a small bellows 61 fixed on the upper inner wall of the metal chassis 1. The small bellows 61 adopts the existing bellows principle, and its internal principle is no longer specifically described. Airflow can be generated by pulling and drawing, and airflow is used to achieve heat dissipation. A push-pull rod 62 that runs through the outside of the small bellows 61 is fixed on the internal piston of the small bellows 61. A reduction motor 63 is fixed to the inside of the metal chassis 1 through a support plate. The reduction motor 63 is electrically connected to an external power supply and is controlled by a control switch. A driving frame 64 is slidably installed above the inner wall of the metal chassis 1. The driving frame 64 reciprocates back and forth above the inner wall of the metal chassis 1. A rotating bar 65 is fixed to one end of the output shaft of the reduction motor 63. A driving rod 66 used in conjunction with the driving frame 64 is fixed on the rotating bar 65. One end of the driving frame 64 is fixed to the end of the push-pull rod 62 through a guide rod 67. The rotating bar 65 is driven to rotate by the reduction motor 63, and then the entire push-pull rod 62 is driven to reciprocate back and forth by the driving rod 66 in cooperation with the driving frame 64 to generate airflow. A connecting pipe 68 is fixed to the inner wall of the metal chassis 1, and a swing pipe 69 is rotatably installed on the inner wall of the connecting pipe 68. The connection between the connecting pipe 68 and the swing pipe 69 has good sealing performance and no air leakage. The surface of the swing pipe 69 is connected with a plurality of heat dissipation outlets 610, and the air outlet of the small bellows 61 is connected with a duct 611, and one end of the duct 611 is connected with the surface of the connecting pipe 68. A foam fan plate 612 is fixed on the surface of the swing pipe 69. The foam fan plate 612 is made of hard foam material and has the characteristics of light weight. In the process of reciprocating swinging with the swing pipe 69, , similar to the principle of a hand-cranked fan, it can push the hot air to the right, so that the small bellows 61 can absorb low-temperature air when inhaling, thereby improving the heat dissipation efficiency. A swing component 613 is arranged between the swing pipe 69 and the driving frame 64. The swing component 613 is used to drive the swing pipe 69 to rotate back and forth to adjust the air outlet direction, thereby improving the heat dissipation efficiency. A water absorption and heat dissipation mechanism 614 is arranged between the small bellows 61 and the small water tank 2, and a transmission dust removal and ventilation mechanism 615 is arranged between the push-pull rod 62 and the metal chassis 1.

[0026] In the embodiment of the present invention, the swing assembly 613 includes a folding bar 6131 fixed below the driving frame 64, a roller 6132 is rotatably installed on the inner wall of the metal chassis 1, a curved groove 6133 is provided on the surface of the folding bar 6131, a row bar 6134 adapted to the curved groove 6133 is fixed below the folding bar 6131, an upper pulley 6135 is fixed on the surface of the roller 6132, a lower pulley 6136 is fixed on the surface of the swing tube 69, the upper pulley 6135 and the lower pulley 6136 are connected by a belt 6137, when the row bar 6134 moves back and forth, the curved groove 6133 can drive the roller 6132 to rotate back and forth, and then the swing tube 69 is driven to swing back and forth with the cooperation of the lower pulley 6136, the upper pulley 6135 and the belt 6137.

[0027] In the embodiment of the present invention, the water absorption and heat dissipation mechanism 614 includes a piston cylinder 6141 fixed below the small air box 61. A piston is slidably installed on the inner wall of the piston cylinder 6141. The piston is made of existing rubber material, which is a prior art and has the same principle as a syringe. During the reciprocating movement, it can pump and squeeze water. One end of the piston is fixed with a connecting rod 6142, and the connecting rod 6142 is fixed to the push-pull rod 62 through a connecting rod 6143. A heat conduction coil 6144 is fixed to the inner wall of the metal chassis 1. One end of the piston cylinder 6141 is communicated with a suction pipe 6145. One end of the suction pipe 6145 penetrates through the metal chassis 1 and is communicated with the bottom of the small water tank 2. The other end of the piston cylinder 6141 is also communicated with a discharge pipe 6146. One end of the discharge pipe 6146 is communicated with one end of the heat conduction coil 6144. The other end of the heat conduction coil 6144 is communicated with a return pipe 6147. One end of the return pipe 6147 penetrates through the metal chassis 1 and is communicated with the upper part of the small water tank 2. A one-way valve 6148 is fixed on the surface of the suction pipe 6145, and a one-way valve 6149 is fixed on the surface of the discharge pipe 6146. The setting of the one-way valve 6148 enables water to only enter the piston cylinder 6141 unidirectionally from the suction pipe 6145. The setting of the one-way valve 6149 enables water to only be squeezed into the heat conduction coil 6144 unidirectionally from the inside of the piston cylinder 6141.

[0028] In the embodiment of the present invention, the transmission ash removal and ventilation mechanism 615 includes a rack 6151 slidably installed on the top of the inner wall of the metal chassis 1. The rack 6151 is fixed to the push-pull rod 62 through an inclined rod 6159. A horizontal shaft 6152 is rotatably penetrated through the metal chassis 1. A gear 6153 meshing with the rack 6151 is fixed on the surface of the horizontal shaft 6152. Fixed shafts 6154 are fixed at both ends of the horizontal shaft 6152. Swing bars 6155 are fixed on the surfaces of the two fixed shafts 6154. Brush plates 6157 are fixed to the inner sides of the two swing bars 6155 through spring rods 6156. Silent bristles 6158 in contact with the corresponding dust-proof nets 5 are fixed to the inner sides of the two brush plates 6157. When the silent bristles 6158 move in contact with the dust-proof nets 5, the sound is small, reducing the impact on the user. The setting of the spring rod 6156 enables the silent bristles 6158 to closely adhere to the surface of the dust-proof net 5, facilitating the dust sweeping work. The rack 6151 can only slide back and forth. During the sliding process, it will drive the gear 6153 to continuously rotate forward and backward, realizing driving the horizontal shaft 6152 to swing reciprocally, and then driving the swing bars 6155 to swing back and forth. Through the relative movement of the silent bristles 6158 and the dust-proof nets 5, the dust is removed, reducing the dust adhesion.

[0029] In the embodiment of the present invention, the heat conduction coil 6144 is made of copper pipe, which has a good heat absorption effect. It can adsorb the heat inside the metal chassis 1 and transfer it to the water in the heat conduction coil 6144 to realize heat adsorption. A water injection pipe is communicated with the upper part of the small water tank 2, and a valve is installed on the surface of the water injection pipe, and water can be injected into the small water tank 2 at any time.

[0030] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] When performing heat dissipation work, the reduction motor 63 is started. The rotation bar 65 is driven to rotate by the reduction motor 63. Then, through the cooperation of the driving rod 66 and the driving frame 64, the entire push-pull rod 62 is driven to perform reciprocating motion back and forth. The small air box 61 continuously generates air flow. The air flow enters the connecting pipe 68 through the conduit 611, then enters the swing pipe 69, and is ejected through the heat dissipation air outlet 610. At the same time, the connecting rod 6142 and the connecting rod 6143 continuously reciprocate with the push-pull rod 62, realizing the continuous reciprocating motion of the piston inside the piston cylinder 6141. When the connecting rod 6142 moves backward, the piston inside the piston cylinder 6141 moves backward, and the water in the small water tank 2 enters the piston cylinder 6141 through the suction pipe 6145 and the check valve 1 6148. When the connecting rod 6142 moves forward, the piston inside the piston cylinder 6141 moves forward, and thus the water in the piston cylinder 6141 is pressed into the heat conduction coil 6144. When the temperature of the metal chassis 1 rises due to heat, it will transfer the heat to the heat conduction coil 6144. The heat conduction coil 6144 will transfer the heat to the flowing water again. The flowing water will move slowly in the heat conduction coil 6144 intermittently, increasing the contact time with the heat conduction coil 6144, and thus realizing heat absorption. Then the water will re-enter the small water tank 2 through the return pipe 6147. During this process, heat will be lost. During the reciprocating sliding process of the driving frame 64, it will drive the folding strip 6131 to reciprocate, and then drive the sliding rod 6134 to reciprocate. When the sliding rod 6134 reciprocates, it can drive the roller 6132 to perform reciprocating rotation in cooperation with the curved groove 6133. Then, under the cooperation of the lower pulley 6136, the upper pulley 6135 and the belt 6137, the swing pipe 69 is driven to reciprocate. During the process of the foam fan plate 612 reciprocating with the swing pipe 69, it can push the hot air to the right, accelerating the discharge of the hot air from the right side, and at the same time facilitating the entry of cold air from the left side. The rack 6151 can only slide back and forth. During the sliding process, it will drive the gear 6153 to rotate forward and backward continuously, realizing the reciprocating swing of the cross shaft 6152, and then driving the swing bar 6155 to swing back and forth. Through the relative movement of the silent brush bristles 6158 and the dust-proof net 5, the dust outside the dust-proof net 5 is swept, facilitating the normal ventilation of the dust-proof net 5.
