The dust removing member 120 includes a dust removing rod 123 and a dust removing brush 124 connected to the dust removing rod 123, where the dust removing rod 123 can rotate relative to the heat dissipating structure 130, so as to drive the dust removing brush 124 on the dust removing rod 123 to rotate relative to the heat dissipating structure 130. When the dust brush 124 rotates relative to the heat dissipation structure 130, the dust brush 124 can remove impurities attached to the heat dissipation structure 130.
Specifically, the dustproof heat sink 100 further includes a first fixing member 141 and a second fixing member 143, and the first fixing member 141 and the second fixing member 143 are fixedly connected to two sides of the heat dissipation structure 130, respectively. Both ends of the dust removing member 120 are rotatably connected to the first fixing member 141 and the second fixing member 143, respectively, that is, both ends of the axial direction of the dust removing rod 123 are rotatably connected to the first fixing member 141 and the second fixing member 143, respectively. It can be appreciated that in other embodiments, the connection position of the dust removing member 120 may be set according to the requirement, so as to ensure that the dust removing rod 123 and the dust removing brush 124 thereon can rotate relative to the heat dissipating structure 130. Alternatively, the first fixing member 141 and the second fixing member 143 are fastened to the heat dissipation structure 130 by screws.
Fig. 5 is a schematic partial structure of the dustproof heat dissipating apparatus 100 according to the present embodiment at the first fixing member 141. Referring to fig. 2-5 in combination, optionally, a first limiting gap 142 is provided on the first fixing member 141, one end of the ash removing rod 123 is limited in the first limiting gap 142, and the ash removing rod 123 can rotate in the first limiting opening, so that the ash removing rod 123 is rotationally connected with the first fixing member 141. The one end of dust remover 120 is provided with spacing boss 126, wears to establish first spacing breach 142 when dust remover 120 in order to rotate with first mounting 141 to be connected, and spacing boss 126 is located the one end that second mounting 143 was kept away from to first mounting 141, and spacing boss 126 is used for keeping away from the wall conflict of second mounting 143 one side with first mounting 141 simultaneously, and the cross-section of spacing boss 126 is greater than the cross-section of first spacing breach 142 promptly, so is spacing to the motion of dust remover 120 along the direction of first mounting 141 to second mounting 143.
Meanwhile, in the process of rotating the ash removing rod 123 relative to the heat dissipating structure 130, the whole dust removing member 120 is switched between an initial state and an intermediate state.

It is understood that the dust removing brush 124 may also be located such that, when the dust removing member 120 is in the initial state, the dust removing brush 124 is located outside the heat dissipating structure 130; when the dust removing member 120 is in the intermediate state, the dust removing brush 124 is positioned in the heat radiating structure 130. That is, when the dust removing member 120 is switched between the initial state and the intermediate state, the dust removing brush 124 enters and exits the heat radiating structure 130.
Specifically, the fan 110 has a chamber 111 for forming an air duct along which an air flow generated by the fan 110 enters the heat dissipation structure 130. When the dust brush 124 leaves the heat dissipation structure 130, the dust brush 124 enters the chamber 111 of the fan 110, that is, in the structure shown in this embodiment, the dust brush 124 is located outside the heat dissipation structure 130, that is, the dust brush 124 is located in the chamber 111 of the fan 110.

The driving member 151 is in driving connection with the driving gear 152, so that the driving gear 152 can rotate under the driving action of the driving member 151. The driving gear 152 is meshed with the transmission gear, and the transmission gear is connected to the dust removing member 120, so that when the driving gear 152 rotates, the driving gear 152 drives the transmission gear to rotate, and the transmission gear drives the dust removing member 120 to rotate, thereby realizing the switching of the dust removing member 120 between the initial position and the intermediate position. Specifically, the driving member 151 is a driving motor, and the transmission gear is riveted to one end of the ash removing rod 123, so as to realize the fixed connection between the transmission gear and the dust removing member 120.
Fig. 6 is a schematic partial structure of the dustproof heat dissipating device 100 according to the present embodiment. Referring to fig. 2-6, alternatively, the end of the ash removing rod 123 near the second fixing member 143 is fixedly connected with the transmission gear, so that the transmission gear, the driving gear 152 and the driving member 151 are all located at the end of the heat dissipating structure 130 where the second fixing member 143 is disposed. Specifically, the second fixing piece 143 is provided with a second limiting notch 144 through which the ash removing rod 123 passes, one end of the ash removing rod 123 away from the limiting boss 126 is located at one side of the second fixing piece 143 away from the first fixing piece 141, and the transmission gear is fixedly connected to the end of the ash removing rod 123.
Alternatively, the driving member 151 has a transmission rod fixedly connected to the driving gear 152, and the driving gear 152 is sleeved on the transmission rod and is in transmission connection with the transmission rod. One end of the transmission rod protrudes from the driving gear 152 to be located between the second fixing member 143 and the driving gear 152. The second fixing member 143 is further provided with a groove 145 for receiving an end portion of the transmission rod.
With continued reference to fig. 2-6, in the present embodiment, the number of the dust removing members 120 is two, and the two dust removing members 120 are a first dust removing member 121 and a second dust removing member 122, respectively, and the first dust removing member 121 and the second dust removing member 122 are disposed on two sides of the heat dissipation structure 130 relatively, so that impurities on the heat dissipation structure 130 are removed through interaction of the first dust removing member 121 and the second dust removing member 122.
Further, the dust removing brushes 124 of the first dust removing member 121 and the dust removing brushes 124 of the second dust removing member 122 are arranged in a staggered manner, so that when the dust removing brushes 124 of the first dust removing member 121 are located in the heat dissipating structure 130, the dust removing brushes 124 of the second dust removing member 122 are located outside the heat dissipating structure 130, and correspondingly, when the dust removing brushes 124 of the first dust removing member 121 are located outside the heat dissipating structure 130, the dust removing brushes 124 of the second dust removing member 122 are located in the heat dissipating structure 130. Specifically, when the dust removing member 120 is in the initial state, the dust removing brush 124 of the first dust removing member 121 is located in the heat dissipating structure 130, and the dust removing brush 124 of the second dust removing member 122 is located outside the heat dissipating structure 130; when the dust removing member 120 is in the intermediate state, the dust removing brush 124 of the first dust removing member 121 is located outside the heat dissipating structure 130, and the dust removing brush 124 of the second dust removing member 122 is located inside the heat dissipating structure 130. Thus, during operation of the dustproof heat dissipation device 100, the dust removing brushes 124 of the first dust removing member 121 and the dust removing brushes 124 of the second dust removing member 122 alternately enter the heat dissipation structure 130.
It should be noted that, in the description of the present embodiment, the phrase "the dust removing brushes 124 of the first dust removing member 121 and the dust removing brushes 124 of the second dust removing member 122 are arranged in a staggered manner" means that the dust removing brushes 124 on the first dust removing member 121 are at an angle to the vertical direction and the dust removing brushes 124 on the second dust removing member 122 are at a different angle to the vertical direction, in other words, if the first dust removing member 121 is translated to the ash removing rod 123 of the first dust removing member 121 and the ash removing rod 123 of the second dust removing member 122 are overlapped, the dust removing brushes 124 of the first dust removing member 121 are not overlapped with the dust removing brushes 124 of the second dust removing member 122.
And because the number of the dust removing pieces 120 is two, correspondingly, the number of the first limiting notches 142 on the first fixing piece 141 is also two, and one ends of the first dust removing piece 121 and the second dust removing piece 122 are respectively and rotatably arranged in the two first limiting notches 142. Similarly, the number of the second limiting notches 144 on the second fixing piece 143 is two, and the other ends of the first dust removing piece 121 and the second dust removing piece 122 are respectively and rotatably arranged in the two second limiting notches 144. Meanwhile, the number of the transmission gears is also two, the two transmission gears are respectively a first transmission gear 153 and a second transmission gear 154, the first transmission gear 153 is fixedly connected to the ash cleaning rod 123 of the first dust removing member 121, the second transmission gear 154 is fixedly connected to the ash cleaning rod 123 of the second dust removing member 122, and the first transmission gear 153 and the second transmission gear 154 are meshed with the driving gear 152, so that the first transmission gear 153 and the second transmission gear 154 can be driven to synchronously operate through the same driving member 151, and the first dust removing member 121 and the second dust removing member 122 are driven to synchronously operate.
Fig. 7 is a schematic cross-sectional view of the heat dissipation structure 130 of the dustproof heat dissipation device 100 according to the present embodiment. Referring to fig. 2-7 in combination, in the present embodiment, the heat dissipation structure 130 includes a plurality of heat dissipation fins 131 sequentially arranged at intervals.

While the fan 110 is running at the first preset rotation speed, the dust removing member 120 is controlled to stop after running for a preset working period, specifically, the driving member 151 is controlled to run for fixing PPS, so that the dust removing member 120 rotates from the initial position to the intermediate position, then the driving member 151 is controlled to rotate reversely, so that the dust removing member 120 is driven to return from the intermediate position to the initial position, and the above process is repeated once again, so that the dust removing member 120 completes the preset working period. It will be appreciated that in other embodiments, the preset duty cycle may be set as desired, for example, by repeating the three reciprocation cleaning process.
S03: the fan 110 is controlled to operate at a second preset rotational speed.
The second preset rotational speed is lower than the first preset rotational speed, and in this embodiment, the second preset rotational speed is a normal rotational speed of the fan 110. When the dust removing member 120 stops running, i.e. the dust removing member 120 stops removing the impurities on the heat dissipating structure 130, the impurities on the heat dissipating structure 130 are almost discharged along with the air flow generated by the fan 110, the fan 110 is decelerated to a normal rotation speed to run, and the air in the housing 200 can be driven to flow, so as to meet the heat dissipating requirement in the housing 200.

Specifically, during operation of the electronic device 10, a dust removal instruction may be sent to the electronic device 10 through a remote controller or an APP within a terminal or the like in communication with the electronic device 10.
Fig. 10 is a step diagram of another dust control method according to the present embodiment. It will be appreciated that the dust-proof heat sink apparatus 100 may also be controlled to operate according to the operating time of the electronic device 10. Specifically, the dust-proof control method includes:
S11, acquiring a starting instruction.
S12: the operating time of the electronic device 10 is obtained.

When the acquired operation time length of the electronic device 10 reaches the preset time length, step S14 is executed, and after the execution of step S14 is completed and the operation of the dust removing member 120 is stopped, step S15 is executed. In the present embodiment, the preset time period is 6 hours, that is, the electronic device 10 performs the automatic dust removing operation every 6 hours of operation. The first preset rotational speed is the full rotational speed of the fan 110, so that the dust removing member 120 has a sufficient wind speed to remove the removed impurities. The second preset rotational speed is less than the first preset rotational speed, and the second preset rotational speed is a normal rotational speed of the fan 110, that is, a rotational speed at which the fan 110 operates to satisfy the heat dissipation requirement when the electronic device 10 works normally.
