Abstract

The invention discloses dustproof foam and relates to the technical field of dust prevention. The dustproof foam comprises at least two foam bodies which are sequentially connected through side surfaces, and bulges are formed at two ends of each foam body. As the plurality of foam bodies are provided and sequentially connected through the side surfaces, the bulges are formed at the two ends of the foam bodies, and a plurality of sealing edges are formed, electronic equipment needing to be sealed can gain multi-layer protection, and the dustproof and sound leakage preventing effects can be guaranteed.

Description

Dustproof foam

Technical field

The present invention relates to dust control technology field, particularly to a kind of dustproof foam.

Background technology

For preventing electronic equipment (for example：Mobile phone, notebook computer, panel computer, display and palm PC PDA etc. set Standby) internal enter dust, and or leakage sound, with reference to Fig. 1～2, would generally corresponding position in the electronic device in prior art Setting dustproof foam.

With reference to Fig. 3, because dustproof foam is according to the foam process molding of prior art, it includes dust-proof main body 1-1, Described dust-proof main body 1-1 be respectively arranged at two ends with raised 1-2, sealing is formed by the raised 1-2 at described dust-proof main body 1-1 two ends Side, when foam is contacted with electronic equipment, simply monolateral sealing, if foam has fold to may result in dust-proof effect difference or leakage sound The problems such as it is impossible to ensure dust-proof with leakproof audio fruit.

Content of the invention

In view of the above problems it is proposed that the present invention so as to provide one kind overcome the problems referred to above or at least in part solve on State a kind of dustproof foam of problem.

According to one aspect of the present invention, there is provided a kind of dustproof foam, described dustproof foam includes：At least two foams Main body, each foam main body passes sequentially through side and is connected, and the two ends of each foam main body are equipped with projection.

Alternatively, in each foam main body, the protruding apex of identical one end is located in same level.

Alternatively, described dustproof foam is formed in one setting.

Alternatively, described dustproof foam is made up of polyurethane, PE Foam or polypropylene.

Alternatively, described foam main body is two.

The present invention passes through to arrange multiple foam main bodys, and each foam main body passes sequentially through side and is connected, and the two of each foam main body End is equipped with projection, is formed with multiple sealing strips, so that needing the electronic equipment of sealing to be obtained in that multilamellar is protected, can Ensure dust-proof and leakproof audio fruit.

Brief description

In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing Have technology description in required use accompanying drawing be briefly described it should be apparent that, drawings in the following description be only this Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, also may be used So that other accompanying drawings are obtained according to these accompanying drawings.

Fig. 1 is the structural representation of dustproof foam in prior art；

Fig. 2 is the side view of the dustproof foam shown in Fig. 1；

Fig. 3 is the profile along A-A direction for the dustproof foam shown in Fig. 1 or Fig. 2；

Fig. 4 is a kind of sectional view of dustproof foam of the present invention；

Specific embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work Embodiment, broadly falls into the scope of protection of the invention.

The dustproof foam of the present embodiment may include at least two foam main bodys that is to say, that its may include two, three or The foam main body of the quantity such as four, taking two foam main bodys as a example to illustrate the present invention below, but not to limit the protection of the present invention Scope.With reference to Fig. 4, described dustproof foam includes：Two foam main bodys 2-1, each foam main body 2-1 passes sequentially through side and is connected, The two ends of each foam main body 2-1 are equipped with raised 2-2.

With reference to Fig. 5, present embodiment is passed through to arrange multiple foam main bodys, and each foam main body passes sequentially through side and is connected, respectively The two ends of foam main body are equipped with projection, are formed with multiple sealing strips, so that needing the electronic equipment of sealing to be obtained in that Multilamellar is protected, and ensure that dust-proof and leakproof audio fruit.

It will be appreciated that for being further ensured that the effect that multilamellar is protected, the raised 2- of identical one end in each foam main body 2-1 2 tops are located in same level.

It should be noted that identical one end can be regarded as being all upper end or is all lower end that is to say, that it is assumed that having a strip The dustproof foam of shape, this dustproof foam includes the first foam main body and the second foam main body, the projection of the first foam main body upper end Top defines first straight line, and the protruding apex of the second foam main body upper end defines second straight line, now, first straight line and Two straight lines are located at same level；

Certainly, the protruding apex of the first foam main body lower end defines the 3rd straight line, the projection of the second foam main body lower end Top defines the 4th straight line, and now, the 3rd straight line and the 4th straight line are located at same level.

For the ease of producing, in present embodiment, described dustproof foam is formed in one setting.

In implementing, for ease of producing, described dustproof foam is made up of polyurethane, PE Foam or polypropylene, certainly, Also can be made using other materials, present embodiment is not any limitation as to this.

The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and Within principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
