since the fixing rod 41 is installed inside the fixing tube 39c for sucking dust blown up by the circuit board, the connecting rod 42 can be installed, and since the connecting rod 42 to which the plurality of fan blades 43 are fixed and which are distributed in an annular array are rotated with the fixing rod 41, when wind acts inside the fixing tube 39c, the fan blades 43 are driven to rotate, and at this time, the connecting rod 42 rotates, and since the filter screen 44 is fixed at one end of the connecting rod 42, air sucked from the inside of the bracket 1 can be sufficiently filtered, so that air blown into the inside of the first air pocket 39a again can be effectively prevented from containing a large amount of dust, and thus, the dust cleaning operation of the circuit board can be ensured, since the brush 46 abutting against the filter screen 44 is fixed on the inner side wall of the fixing tube 39c, namely, when the filter screen 44 rotates, the brush 46 can clean the dust on the filter screen 44, so as to avoid the situation that the filter screen 44 is blocked; because the water jacket 51 is rotated through the fixed column 52 in the bracket 1, and the water jacket 51 is connected with an external water pipe, and external high-pressure water washes the conveyed circuit board through the water jacket 51, the cleaning effect of the circuit board can be further increased, because the push rod 59 is fixed outside the rotating shaft 33, when the rotating shaft 33 blows the circuit board, the push rod 59 can be synchronously driven to rotate continuously, so that the push rod 59 can continuously extrude the sliding plate 58 to perform reciprocating sliding, because the sliding plate 58 is fixed with the top plate 57 fixed on the rack 55, and because the rack 55 is meshed with the gear 54 fixed outside the fixed column 52, when the rack 55 performs continuous reciprocating movement under the elastic force of the push rod 59 and the spring 56, the gear 54 can continuously swing, therefore, the water jacket 51 can swing continuously, the circuit board can be washed in all directions by water flow, the washing quality is ensured, because the fixing sleeve 62 is communicated with the protecting sleeve 37 through the second air pipe 61, air in the protecting sleeve 37 can enter the air storage tank 65 through the second air pipe 61 and then is blown out from the air outlet holes 66, because the heating block 67 in the inverted-splayed structure is fixed on both sides of each air outlet hole 66, the air blown out from the air outlet holes 66 can carry heat of the heating block 67 out to blow towards the cleaned circuit board, the circuit board can be heated and dehydrated to ensure subsequent use, and because the second air pipe 61 is also connected with the second air sleeve 64 through the third air pipe 63, air in the second air pipe 61 can also be blown out from the second air sleeve 64, the circuit board after the heating dehydration can be blown and cooled, and subsequent use is guaranteed.
