Abstract

The utility model relates to a demountable dustproof filter device for the air inlet of a machine case, which comprises a demountable shell and a filter net. The demountable shell is a breathable frame-tablet body designed as the external shape of the network communication machine case which can be connected with the external of the air inlet simply via a certain connection mode. The filter net is arranged on the inner face of the demountable shell, which can be along with the demountable shell to make the air inlet be hidden perfectly. As a result, the heat dissipation air blown by a fan can get through the filter into the inner of the machine case which can be kept the high cleanliness after used for a long time. Meanwhile, the utility model of the dustproof filter device can be assembled or be disassembled for changing the filter net to avoid the problem of turning off the net communication machine case before cleaning or dedusting, which has the advantages of simple operation and great dustproof effect.

Description

But it is special-purpose at the removal formula dustproof filtering device of network communication with the cabinet air inlet

Technical field

The utility model relates to a kind of dustproof filtering device, particularly be a kind ofly can not install or removal under the off-mode, by so that cabinet inside can continue to keep high-cleanness, high in long-term the use.

Background technology

Network communication comprises the networking telephone, shopping at network, various fields such as the Web-based instruction, quite general, the whole world almost all has the people to use in online all the time, and for meeting the use needs, main frame that network communication is used or cabinet must have fallow land the whole year and continue to keep open state: the inside of the main frame of network communication use or the cabinet air inlet that generally all is provided with the heat transmission fan and matches again, enter cabinet inside in order to order about air by air inlet, discharge outside by the gas outlet again, by the cabinet inside electronic component is produced radiating effect, make cabinet can maintain the optimum operation environment, to guarantee the service efficiency of network communication with main frame or cabinet.Only, the existing network communication all only is provided with fence gate formula or slot type air inlet with main frame or cabinet, does not have the dustproof filter function, though but the indoor air conditioning of machine room still is difficult to avoid dust impurity etc. to infiltrate cabinet by air inlet after using over a long time; Network communication earlier be opened casing after the shutdown (shutdowns) again with cabinet as another, and the beginning can be cleaned or dedusting work, causes and shuts down and multiple puzzlement such as operation procedure is miscellaneous; The utility model is to improve at the shortcoming of existing cabinet air inlet.

Summary of the invention

The utility model main purpose is, but provides a kind of special use at the removal formula dustproof filtering device of network communication with the cabinet air inlet, can not install or removal under the off-mode, by so that cabinet inside can continue to keep high-cleanness, high in long-term the use.

For achieving the above object, the technical solution adopted in the utility model is, but use the removal formula dustproof filtering device of cabinet air inlet in network communication for a kind of special use, it is to utilize an outer cover and a filter screen to constitute, and this outer cover is to cooperate the external shape design of network communication with the air inlet of cabinet, but be located at simple cover on the outside of air inlet, and this filter screen is to be laid on the inner face of this outer cover, can completely cover gas port.

Below in conjunction with accompanying drawing, to this novel above-mentionedly is described in more detail with other technical characterictic and advantage.

Embodiment

For making the utility model clear and definite more full and accurate, enumerate preferred embodiment now and cooperate following diagram, structure of the present utility model and technical characterictic thereof are described in detail as the back:

One network communication cabinet 1, comprise a common flat unit cabinet such as Fig. 1, shown in 2 or a cuboid formula cabinet such as a Fig. 3, shown in 4, its heat transmission fan (not shown) generally is arranged on the inner edge surface place of a cabinet inside and a close shell surface (as front or rear side), and on the corresponding shell surface 10 (as front or rear side) of cabinet 1, cooperate this heat transmission fan and an air inlet 11 is set, this air inlet 11 generally is provided in a side of on the shell surface 10 of front or rear side of cabinet 1 as Fig. 1, shown in 3, enter cabinet 1 inside and order about air by air inlet 11 by the heat transmission fan, discharge outside by the gas outlet 13 that is configured on other shell surface 12 again, this gas outlet 13 generally is provided in a side of on the shell surface 12 of a left side or right two side faces as Fig. 1, shown in 3, by cabinet 1 internal electron part is produced radiating effect, make cabinet 1 inside can maintain the optimum operation environment, to guarantee the best service efficiency of network communication with main frame or cabinet.

Principal character of the present utility model is: but at the outer setting one removal formula dustproof filtering device 2 of network communication with the air inlet 11 of cabinet 1, but should removal formula dustproof filtering device 2 be to utilize an outer cover 20 and a filter screen 21 to constitute, wherein, this outer cover 20 is breathable frame lamellar bodies, its shape is to cooperate the external shape design of network communication with the air inlet 11 of cabinet 1, outer cover 20 can be located on the outside of air inlet 11 by connecting structure 3, and outer cover 20 is provided with air-vent 201 for circulation of air again; And this filter screen 21 is to be laid on the inner edge surface 202 of this outer cover 20, and when making outer cover 20 be located at air inlet 11 outside, filter screen 21 can completely cover gas port 11; By this, making the outside air of introducing by the heat transmission fan is earlier through entering the inside of cabinet 1 behind the filter screen 21 on outer cover 20 inner edge surfaces 202 again, by with the dust in the filtered air, impurity, make cabinet 1 in long-term the use, its inside still can continue to keep high-cleanness, high; Again at cabinet 1 not under the off-mode, can directly install or removal outer cover 20 to change filter screen 21, make by ease of Use and can reach the dustproof filter effect.

Refer again to Fig. 2,4, be provided with connecting structure 3 between the outside of this outer cover 20 and air inlet 11, so that but outer cover 20 simple cover are located on the outside of air inlet 11, and the mode of connection of this connecting structure 3 is regardless of, comprise locking mode, chimeric mode etc., wherein the connecting structure shown in Fig. 2,43 is to disclose a kind of locking mode, and it is to utilize several locking parts 30 as screw, make locking part 30 lockings in the corresponding lockhole 31 of air inlet 11 outsides, and make outer cover 20 lockings on the outside of air inlet 11; This locking part 30 can be combined into one as shown in Figure 1, 2 with outer cover 20 again, or passes on the outer cover 20 mating holes 32 in addition shown in Fig. 3,4, but outer cover 20 ease of Use on the outside of air inlet 11 is installed or removal, by to reach the effect of simplified control.

More than explanation is novel just illustrative for this; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection range of the present utility model.
