Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment aims to provide a kind of dustproof ventilation unit and communication equipment, can realize the automatic dedusting of Air Filter.
As shown in Figure 1, the dustproof ventilation unit that the utility model embodiment provides comprises Air Filter 1, electromagnet 2, moving contact 3 and fixed contact 4;
Air Filter 1 and electromagnet 2 are oppositely arranged, and moving contact 3 is connected on the side surface of Air Filter 1 away from electromagnet 2, and in the present embodiment, moving contact 3 is a metal spring leaf; It is pointed out that to be the side structure of Air Filter 1 shown in Fig. 1 that the Facad structure of normally used Air Filter 1 can comprise framework 11 and be arranged on the grid 12 that gathers in the framework 11 as shown in Figure 2.
Dustproof ventilation unit of the present utility model for when electromagnet 2 produces magnetic, can be attracted by electromagnet 2, and Air Filter 1 is provided with metal part, and this metal part has ferromagnetic property, can be attracted by the magnetic of electromagnet.Concrete, if Air Filter 1 self comprises metal structure, for example, framework 11 is the framework of metal material, so, the metal framework 11 of Air Filter 1 promptly can be used as described metal part; And if Air Filter 1 is the insulation material, so, need be at Air Filter 1 near described metal part be installed on the side surface of electromagnet, to guarantee that Air Filter 1 can be attracted by the magnetic of electromagnet.And in order to guarantee the dustproof draught effect of grid 12, described metal part is preferably mounted on the framework 11 at Air Filter edge.
Operation principle schematic diagram as shown in Figure 3, when Air Filter 1 did not need to carry out dust removal process, power supply 5 was not powered, and Air Filter 1 is on the position of operate as normal, and moving contact 3 and fixed contact 4 are in contact with one another; When Air Filter 1 need carry out dust removal process, power supply 5 is electromagnet 2 power supplies, when being electromagnet 2 energisings, because moving contact 3 and fixed contact 4 contact, electromagnet 2 place circuit turn-ons have electric current to pass through in the inductance coil 21, electromagnet 2 produces magnetic, because Air Filter 1 and electromagnet 2 are oppositely arranged, the metal part on the Air Filter 1 is attracted by electromagnet 2, therefore, Air Filter 1 will be to electromagnet 2 motions, simultaneously, because moving contact 3 is connected on the Air Filter 1, the motion of Air Filter 1 will drive moving contact 3 and move simultaneously, moving contact 3 is disconnected with fixed contact 4 to be contacted, electromagnet 2 disconnects with power supply 5 and being connected, and does not have electric current to pass through in the inductance coil 21, and electromagnet 2 will lose magnetism, at this moment, Air Filter 1 will be under self elastic force effect, return-to-home position, and moving contact 3 is contacted again with fixed contact 4.Like this, electromagnet 2 place circuit conductings once more will be carried out said process, and so forth again.
In the above-mentioned reciprocal process, Air Filter 1 repeats the reciprocal vibrations returned after electromagnet motion, by the vibrations of Air Filter, can promptly realize the automatic dedusting of Air Filter with the shake of the dust on the Air Filter from Air Filter.Like this, just do not need frequent the replacing and the cleaning Air Filter, be convenient to the maintenance of communication equipment, reduced the maintenance cost of communication equipment, improved the reliability of communication equipment.
It is pointed out that in the present embodiment that the bottom of Air Filter 1 is fixed, when the metal part on the Air Filter 1 was attracted by electromagnet 2, the top of Air Filter 1 was to the direction deflection of electromagnet 2, and electromagnet 2 is when losing magnetism, the top of Air Filter 1 will be under the effect of self elastic force, and pop into position is put.Be understandable that, the utility model to Air Filter 1 how to electromagnet 2 motions and how return-to-home position is not done qualification, under the attraction of electromagnet 2, Air Filter 1 position motion in whole or in part, after electromagnet 2 loses magnetism, Air Filter 1 can rely on self elastic force return-to-home position, also can be under the effect of external force return-to-home position.
Further, as a kind of improvement of present embodiment, as shown in Figure 4, the dustproof ventilation unit of present embodiment, also can comprise block 5, block 5 is arranged on Air Filter 1 on electromagnet 2 travel directions, by the barrier effect of block 5, can limit the motion amplitude of Air Filter 1, make Air Filter 1 under the attraction of electromagnet 2, strike block 5 and stop, can also being that the reciprocal vibrations of Air Filter 1 increase impact, the shake that is beneficial to dust on the Air Filter 1 more from.In addition, the position that contacts with block 5 during Air Filter 1 motion can be provided with cushion pad 13, reduces the damage of the bump of Air Filter 1 and block 5 to Air Filter 1 and block 5.
Further, a kind of improvement as present embodiment, the dustproof ventilation unit of present embodiment also can comprise the dust detection probe, is used to detect the laying dust amount on the Air Filter 1, so that whether the control device decision of the user or the ventilation unit that should prevent dust needs to carry out the dust removal operation of Air Filter 1.Wherein, the dust detection probe can be arranged on the Air Filter 1 or on the position with respect to Air Filter 1, can monitor the laying dust amount on the Air Filter.
It is to be noted in addition, among the utility model embodiment, the shape and the concrete structure of moving contact 3 and fixed contact 4 are not limit, but both need to guarantee: when Air Filter 1 is in or sets back, moving contact 3 and fixed contact 4 are in or the state that resumes contacts, when Air Filter 1 motion, moving contact 3 will contact with fixed contact 4 disconnections along with the motion of Air Filter 1.
Accordingly, the utility model embodiment also provides a kind of communication equipment, comprise ventilating opening, the place is provided with dustproof ventilation unit at described ventilating opening, wherein, the dustproof ventilation unit that described dustproof ventilation unit adopts the utility model embodiment to provide, preamble has been described in detail, specifically please see preamble for details and describe, repeat no more here.
The communication equipment that the utility model embodiment provides can be realized the automatic dedusting of Air Filter, like this, does not just need frequent the replacing and the cleaning Air Filter, is convenient to the maintenance of communication equipment, has reduced the maintenance cost of communication equipment, has improved the reliability of communication equipment.
Wherein, the Air Filter of dustproof ventilation unit is arranged on the base plate of present embodiment communication equipment usually, dust from the Air Filter shake from after, will be scattered or be accumulated on the base plate.For the ease of the cleaning of dust, can through hole be set on base plate, concrete, because the dust shake behind Air Filter, is scattered usually or is accumulated on the position of closing on Air Filter on the base plate, therefore, through hole is arranged on the position that described base plate closes on Air Filter, and dust can be cleared up away by through hole.
