Dust described in when preventing described fan forward in dust collection bag is inhaled into the enclosure interior of described electronic equipment, described electronic equipment also comprises: second blocks parts and the second control assembly, described second blocks parts is arranged at the opening part of described dust collection bag, described the second control assembly, for according to the direction of rotation of described fan, is controlled described second and is blocked the unlatching of parts or close.In the time that described fan rotates with described first direction, described in described the second control assembly control, second blocks parts and closes, in the time that described second blocks parts and closes, can block the opening of described dust collection bag, prevent that the dust in described dust collection bag is inhaled into the enclosure interior of described electronic equipment.When described fan is during with the rotation of described second direction, second blocks parts and opens described in described the second control assembly control, and in the time that described second blocks parts and open, described dust collection bag can be collected the dust being blown off in described dust proof member.
Certainly, described electronic equipment also can not comprise described the second control assembly, only comprises that second blocks parts, and described second blocks that parts are the same to be stated first to block parts the same, also can, under the control of the wind-force of described fan, automatically open or close.
In addition, when dust proof member is in the above-described embodiments metal material, likely can produce static, the static of generation can strengthen the absorption dynamics to dust, the dust that the wind-force that described fan produces likely cannot blow off in described dust proof member.Therefore, in example of the present invention, described electronic equipment can also comprise an anti-static part, is connected, for preventing that described dust proof member from producing static with described dust proof member.Described anti-static part can be realized by the grounding pin of the arbitrary electronic device in described electronic equipment.
Described automatic dust removing apparatus is all identical with structure and the operation principle of the automatic dust removing apparatus in above-described embodiment, is not described in detail at this.
The embodiment of the present invention also provides a kind of automatic dust removing method, and described automatic dust removing method is applied in an electronic equipment, and described electronic equipment comprises a housing, on described housing, is provided with ventilating opening, said method comprising the steps of:
Step 1, arranges one for stopping or the dust proof member of the dust that adsorption gas flow carries at described ventilating opening place;
Step 2, arranges a fan in the inner side of described dust proof member;
Step 3, control described fan with first direction or contrary second direction rotation, in the time that described fan rotates with described first direction, can guide extraneous air-flow to enter described enclosure interior by described dust proof member, described dust proof member can stop or adsorb the dust that extraneous air-flow carries, in the time that described fan rotates with described second direction, can guide described enclosure interior air-flow to discharge by described dust proof member, the internal gas flow of the discharge dust that stops or adsorb in described dust proof member that can blow off.
Described electronic equipment is all identical with structure and the operation principle of the electronic equipment in above-described embodiment, is not described in detail at this.
In sum, embodiments of the invention have the following advantages:
Dustproof, avoid because of dust in electronic equipment accumulate the heat radiation that too much brings, power consumption greatly, the problem such as electronic device useful life is short.
Automatic dust removing, user does not need manually dust proof member to be cleaned to dedusting.
Effectively collect dust.
Realize simply, cost is less.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
