Abstract

A novel dustproof net for mobile phone and computer loudspeaker holes comprises a net-shaped dustproof portion and a bonding portion which is integrally molded with the dustproof portion, wherein the dustproof portion is a dustproof and waterproof material layer with a specified shape, and the bonding portion is a double-sided adhesive layer; and the double-sided adhesive layer is hollow, and the dustproof and waterproof material layer is smaller than the double-sided adhesive layer and completely covers the hollow portion of the double-sided adhesive layer. According to the novel dustproof net of the utility model, inner holes are formed on the double-sided adhesive layer and the dustproof and waterproof material layer through the cutting of a round-robin die-cutting machine; and the dustproof net is molded with one step through a circular knife. The periphery of the dustproof net cut through the above method is smooth. With the dustproof net cut through the above method adopted, the problems such as unsmooth sounding and dusting in die cutting can be effectively solved; the production of products with specified shapes can be realized effectively; waste discharge operation of machining process is simple and easy, and therefore, waste can be discharged effectively, and labor can be saved; the quality of the products is excellent; the novel dustproof net is suitable for mass production; and the novel dustproof net is further advantageous in strong practicability and broad market prospect.

Description

A kind of novel Air Filter for mobile phone, computer bellmouth orifice
Technical field
The utility model relates to the Air Filter that a kind of bellmouth orifice uses, and especially relates to a kind of novel Air Filter for mobile phone, computer bellmouth orifice.
Background technology
Electronic installation is equiped with loud speaker usually, therefore offers bellmouth orifice in the position of the corresponding loud speaker of electronic installation.For avoiding dust or steam to be entered in the electronic installation by this bellmouth orifice, influence the effect of loud speaker or the function of the other electron component in the electronic installation, need to use the bellmouth orifice Air Filter that bellmouth orifice is carried out the protection of dustproof and waterproof vapour usually.Existing a kind of bellmouth orifice Air Filter comprises dust layer and layers of two-sided, offers through hole in the middle of this layers of two-sided, and the area of this dust layer is less than the area of this layers of two-sided and cover this through hole.Yet this kind bellmouth orifice Air Filter manufacture method is complicated, and cost is higher.
When using the Air Filter of conventional shape, by double faced adhesive tape the dustproof and waterproof material is pasted on mobile phone or the notebook loud speaker, the hollow space of double faced adhesive tape is over against the vocal hole of loud speaker, and both effective dustproof and waterproof did not influence sounding again.But, because after the above-mentioned die-cutting process processing of the Air Filter of this shape process, the dustproof and waterproof material is the same big with double faced adhesive tape, with regard to entire product, can only paste by single face, loud speaker bonds on other structural members more if desired, just can not realize.In order better to use Air Filter, also be vital to the cross cutting of Air Filter.
Summary of the invention
The utility model purpose provides a kind of novel Air Filter for mobile phone, computer bellmouth orifice, when solving existing Air Filter cross cutting easily pronunciation smooth, play dirt, joint face is little, cost high-technology problem.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the novel Air Filter that is used for mobile phone, computer bellmouth orifice, comprise netted dustproof portion and with the integrated adhesive portion of portion of preventing dust, wherein dustproof portion is the dustproof and waterproof material layer with regulation shape, and adhesive portion is layers of two-sided; Described layers of two-sided is hollow shape, and the dustproof and waterproof material layer also covers the hollow space of layers of two-sided fully less than layers of two-sided.
As preferably, described layers of two-sided gluing surface is acrylic acid glue or rubber, and the adhesive tape average adhesion is 50~100g/mm, and the adhesive tape average thickness is 0.05~0.15mm.
As preferably, described dustproof and waterproof layer is the nylon screen pack.
As preferably, two mucilage glue surfaces of described layers of two-sided are bonding with the silicone oil face of single silicon release liners and single silicon carrier film respectively, and wherein the mucilage glue surface of the non-silicone oil face of single silicon carrier film and single face glue is bonding.
As preferably, dustproof and waterproof material laminar surface is provided with single face glue, and the mucilage glue surface of this single face glue and dustproof and waterproof material layer are bonding.
As preferably, described layers of two-sided and dustproof and waterproof material are compound, and be straight tiltedly outer in cross cutting is selected for use, the circular knife machine of 30 ° of knife up 1.8mm of angle.
The utility model cuts out endoporus by circular knife machine with double faced adhesive tape, dustproof and waterproof material layer, and makes the Air Filter one-shot forming by dise knife, and the Air Filter periphery of this method cross cutting is smooth, pronounces freely, rises problems such as dirt when efficiently solving cross cutting.Realize the production of regulation infrastructure product effectively, and the waste discharge of this manufacturing procedure operation is simple, can effectively get rid of waste material, save manually, and good product quality is suitable for large batch of production.And implementation result is good, has very strong practicality, and market prospects are wide.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A shown in Figure 1-A cutaway view.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Fig. 1 is structural representation of the present utility model; Fig. 2 is A shown in Figure 1-A cutaway view.By Fig. 1 in conjunction with Fig. 2 as can be known, the novel Air Filter that should be used for mobile phone, computer bellmouth orifice, mainly form by netted dustproof portion and with the integrated adhesive portion of portion of preventing dust, wherein dustproof portion is the dustproof and waterproof material layer 3 with regulation shape, and adhesive portion is layers of two-sided 2; Described layers of two-sided 2 is hollow shape 4, and dustproof and waterproof material layer 3 also covers the hollow space of layers of two-sided 2 fully less than layers of two-sided 2.
Layers of two-sided 2 is used nonwoven fabrics, PET is as base material or do not have base material, and adhesive layer is acrylic acid glue or rubber, and the adhesive tape average adhesion is 50~100g/mm, and the adhesive tape average thickness is 0.05~0.15mm.Two mucilage glue surfaces of layers of two-sided 2 are bonding with the silicone oil face of single silicon release liners 6 and single silicon carrier film 1 respectively, and wherein the mucilage glue surface of the non-silicone oil face of single silicon carrier film 1 and single face glue 7 is bonding.Dustproof and waterproof layer 3 be the nylon screen pack, and dustproof and waterproof layer 3 surfaces are provided with single face glue 5, and the mucilage glue surface of this single face glue 5 is with dustproof to reach waterproof layer 3 bonding.
