as shown in fig. 6, in comparative example one, another embodiment of the present invention is: the surface of the telescopic sleeve 23 is provided with a plurality of through cavities 34, the middle parts of the side walls of the through cavities 34 are arranged into inwards concave arc shapes, the inside of the through cavities 34 is provided with plugging balls 35, and elastic pull ropes 36 are connected between the plugging balls 35 and the side walls of the through cavities 34; when the fan blade 7 carries out heat dissipation work, because the telescopic sleeve 23 is in the extension state at this moment, the clearance is produced between shutoff ball 35 and the groove that link up to be convenient for the air current that fan blade 7 promoted passes through, when filter screen 4 clear up, along with the shrink of telescopic sleeve 23, link up the groove and can laminate the parcel to shutoff ball 35, thereby make and link up the groove and be in stable closed state, further reduce the air current and follow baffle 16 and flow outward, lead to the condition that the tolerance of shower nozzle 14 reduces.
Meanwhile, the invention provides a projector, which comprises the heat dissipation structure of any one of the above.
Working principle: when the heat radiation structure is used, the motor 6 drives the fan blades 7 to rotate, the fan blades 7 can continuously push air to one side of the air outlet 3 when rotating, so that air flow for heat radiation can be formed in the air inlet sleeve 5, when impurities on the surface of the filter screen 4 at the air inlet 2 are more, the electromagnet 11 can be controlled to work, after the electromagnet 11 repels the baffle 9, the baffle 9 is driven to slide into the air inlet sleeve 5 from the sliding cavity 8 and block the outer end of the air inlet sleeve 5, and meanwhile, the automatic blocking assembly is controlled to simultaneously block the inner end of the air inlet sleeve 5, when the fan blades 7 continue to rotate, the fan blades 7 can push the air flow in the closed air inlet sleeve 5 to flow out from the air outlet 13 and the guide pipe 15, and the air flow can blow the impurities on the surface of the filter screen 4 after flowing out of the spray pipe, so that a 'back flushing' effect of the filter screen 4 can be achieved, the filter screen 4 at the air inlet 2 is cleaner, and the heat radiation effect of the heat radiation structure on the projector is improved; when the inside of the shell dissipates heat, the air flow can jack the barrier strips 18 away from the air inlet holes 17 under the pushing of the fan blades 7, so that the air flow can effectively flow in the shell and dissipate heat, when the filter screen 4 needs to be cleaned, the magnetic material of the baffle 9 can attract the metal sheets 19 simultaneously along with the sliding of the baffle 9 into the air inlet sleeve 5, so that the barrier strips 18 can be forcefully pressed on one side of the air inlet holes 17 and block the air inlet holes 17, the sealing effect of the separation plates 16 is achieved, and the fan blades 7 can effectively push the air flow in the air inlet sleeve 5 to clean the filter screen 4; when the air inlet 12 is in a normally open state, at the moment, when the fan blades 7 are used for radiating heat, part of hot air in the shell can be sucked into the air inlet sleeve 5 from the air inlet 12 in a reciprocating manner, so that the projector is internally formed into a thermal cycle, at the moment, the air inlet 12 can be blocked by the blocking block 20 under the action of the elastic rope 21 by arranging the blocking block 20 structure at the air inlet 12, so that the condition of thermal cycle in the shell is effectively reduced, when the filter screen 4 is cleaned, the air inlet sleeve 5 is blocked by the baffle 9, the blocking block 20 is pushed away from the air inlet 12 by the ejector rod 22, and the cleaning work of the filter screen 4 can be smoothly carried out; when the baffle plate 9 slides from the inside of the air inlet sleeve 5 to the inside of the sliding cavity 8, the baffle plate 9 can press the gas in the telescopic bags into each telescopic sleeve 23 through the air pipe 24, so that the barrier strips 18 are stably jacked up from the air inlet holes 17 after the telescopic sleeves 23 are expanded and stretched, the gas flow during heat dissipation of the fan blades 7 is facilitated, meanwhile, when the filter screen 4 is cleaned, the air in the telescopic sleeves 23 can be sucked in the telescopic bags in the stretching process along with the sliding of the baffle plate 9 into the inside of the air inlet sleeve 5, the telescopic sleeves 23 are contracted, and the barrier strips 18 are pulled to be more forcefully attached to one side of the air inlet holes 17, so that the air inlet holes 17 can be blocked more effectively; when the fan blades 7 push the air to flow into the total flow groove 27, a part of the air flows out of the spray head 14 and blows off and cleans impurities on the filter screen 4, and at the same time, after a part of the air is sprayed out of the diversion groove 28, the sliding block 26 is driven to slide along the sliding rod 25 by the impact force of the air flow, so that the spray point of the spray head 14 on the filter screen 4 can move in the vertical direction, and the filter screen 4 can be cleaned more fully and uniformly; when the sliding block 26 slides under the action of the air flow in one of the split grooves 28, the sliding block 26 can drive the point touch switch 30 to move to the position of the pressure lever 31, and the pressure lever 31 is used for extruding the point touch switch 30, so that the air flow of the control valve 29 (can be a two-way valve) is switched to the other split groove 28, and the sliding block 26 can slide back and forth on the sliding rod 25, so that the cleaning effect of the spray head 14 on the filter screen 4 is further improved; when the sliding block 26 drives the flow dividing groove 28 to move to the elastic beating plate 33, the air flow impacts the end part of the elastic beating plate 33, so that the elastic beating plate 33 can continuously rotate, and meanwhile, the end part of the elastic beating plate 33 can beat the filter screen 4, so that the surface of the filter screen 4 continuously shakes, and the falling of dust and impurities on the filter screen 4 is promoted.
