[0028] As Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 9 illustrated, the filter assembly (4) includes a filter screen (41) and a rotating block (42). The filter screen (41) is provided with two groups. One group of the filter screen (41) is slidably installed on the bottom of the first fixed plate (1). The other group of the filter screen (41) is slidably installed on the top of the second fixed plate (2). The two sides of the two groups of filter screens (41) are rotatably installed with the rotating block (42). The filter screen (41) can filter air to prevent dust in the air from entering the internal electronic products such as computers or mobile phones. The rotating block (42) can quickly disassemble the filter screen (41). The cleaning assembly (6) includes a fixed frame (61) and a roller brush (62). The fixed frame (61) is fixedly installed on the bottom of the first fixed plate (1). The inner wall of the fixed frame (61) is rotatably installed with the roller brush (62). The roller brush (62) is movably installed with the filter screen (41).

[0029] As Figure 1 , Figure 3 , Figure 4 , Figure 8As shown, the clamping mechanism (7) comprises first slide rods (71), second slide rods (72), third slide rods (73) and clamping blocks (74), the first slide rods (71) are provided in two groups, the two groups of first slide rods (71) are movably installed on the inner walls of the first fixed plate (1) and the second fixed plate (2), one end of the first slide rod (71) is fixedly installed with the third slide rod (73), the surface of the third slide rod (73) is slidably installed with the second slide rod (72), the first slide rod (71) is movably connected with the second slide rod (72), the clamping blocks (74) are provided in two groups, the two groups of clamping blocks (74) are respectively threadedly installed on the ends of the first slide rod (71) and the second slide rod (72) away from each other, and the clamping blocks (74) are movably installed with the first fixed plate (1) and the second fixed plate (2). The reset assembly (8) comprises fixed rings (81) and tension springs (82), the fixed rings (81) are provided in two groups, the two groups of fixed rings (81) are respectively fixedly installed on the surfaces of the first slide rod (71) and the second slide rod (72), and the fixed rings (81) are respectively slidably installed with the inner walls of the first fixed plate (1) and the second fixed plate (2), and the two groups of fixed rings (81) are fixedly installed with the tension springs (82) on the sides close to each other.

[0030] In work, first, the two groups of clamping blocks (74) are pulled outwards to clamp the mobile phone or the tablet computer and other electronic products, when the clamping blocks (74) are pulled out, the first slide rod (71) and the second slide rod (72) will slide to one side, while the second slide rod (72) will slide to the opposite direction, at the same time, the two groups of fixed rings (81) will move synchronously with the first slide rod (71) and the second slide rod (72), when the fixed ring (81) moves, the tension spring (82) will be stretched, until the clamping block (74) can clamp the electronic product, finally, the cooling fan (3) is started to rotate to cool the electronic product, when the filter screen (41) needs to be cleaned after long time use, the user needs to press one side of the rotating block (42) to make it rotate, so that the longer end of the rotating block (42) rotates out, then the user pulls the rotating block (42) to pull out the filter screen (41), when the filter screen (41) is pulled out, the roller brush (62) will scrape off the dust on the surface of the filter screen (41), so as to realize cleaning.

[0031] When the user needs to expand the heat dissipation area, he only needs to rotate the second fixed plate (2) to make it parallel to the first fixed plate (1). Before rotating the second fixed plate (2), the clamp block (74) needs to be threadedly disassembled. After unfolding, the disassembled clamp block (74) needs to be threadedly installed on the side of the first fixed plate (1) away from the second fixed plate (2). It can also be chosen not to be installed. Then the top of the first fixed plate (1) and the second fixed plate (2) is adsorbed on the bottom of the notebook or tablet. If the notebook and tablet have no adsorption function, a magnetic adsorption sticker is needed. Because the contact area of the first fixed plate (1) and the second fixed plate (2) is improved after unfolding, the magnetic attraction of the first magnetic block (91) and the second magnetic block (92) can also ensure that the first fixed plate (1) and the second fixed plate (2) will not fall off during use. At the same time, the user can also threadedly install the unfolded first fixed plate (1) and the second fixed plate (2) at other heat dissipation equipment through the installation hole (50). After use, it only needs to be folded again. When unfolding, the heat dissipation fan (3) on the inner wall of the second fixed plate (2) needs to be reversed to ensure that it can cooperate with the first fixed plate (1) to dissipate heat.
