The invention discloses a bidirectional digital set top box with an automatic periodic dust removal structure. The set top box comprises a DEH instruction module, one side of the DEH instruction module is unidirectionally and electrically connected with a servo plate; one side of the servo board is connected with a power amplifier board; one side of the power amplifier board is unidirectionally and electrically connected with a servo valve, one side of the servo valve is connected with a hydraulic servo-motor, the other side of the hydraulic servo-motor is connected with a feedback board, thefeedback board is unidirectionally and electrically connected with the power amplifier board, the feedback board is unidirectionally and electrically connected with the servo board, one side of the feedback board is provided with a wire pressing mechanism, and the top end of the hydraulic servo-motor is provided with a monitoring mechanism. In the set top box, under the action of the dust removalmechanism, the electric telescopic rod can be controlled to work through the timing switch, so that the electric telescopic rod regularly drives the brush to scrape back and forth on the surface of the first dustproof net to clean the first dustproof net, the brush can be extruded to be tightly attached to the first dustproof net through the preset first reset spring, the dust removal effect is improved, and the situation that the device cannot normally dissipate heat due to dust blockage is prevented.
Description
technical field [0001] The invention relates to the technical field of digital set-top box equipment, in particular to a two-way digital set-top box with an automatic and regular dust removal structure. Background technique [0002] The set-top box refers to the box on the top of the TV. It is a kind of household appliance that expands the functions of the TV. The set-top box is divided into analog set-top boxes and digital set-top boxes according to the types of signals received. The analog set-top boxes receive analog signals, and the digital set-top boxes receive digital signals. Chips are used to complete the operation, and the top of the device is usually equipped with a cooling net to dissipate heat from the internal components. [0003] The existing two-way digital set-top box does not have the function of automatically cleaning the heat dissipation net during its use, so that the long-term use of the heat dissipation net accumulates dust, causing blockage, reducing t...
