BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a structural schematic diagram of an embodiment of the utility model of an oil mist adsorption cloth containing electrostatic cotton;

[0019] In the figure: 1. External skeleton cloth layer; 2. Internal skeleton cloth layer; 3. Asbestos layer; 4. Electrostatic cotton layer; 5. Meltblown cloth layer; 6. Activated carbon powder layer. DETAILED DESCRIPTION

[0020] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0021] Example

[0022] like Figure 1 As shown, the oil mist adsorption cloth containing electrostatic cotton in the embodiment comprises an outer skeleton cloth layer 1 and an inner skeleton cloth layer 2 which are stacked and connected, a flame retardant layer and an adsorption layer are stacked between the outer skeleton cloth layer 1 and the inner skeleton cloth layer 2, and the adsorption layer comprises an electrostatic cotton layer 4.

[0023] Through such a design, the electrostatic cotton layer 4 can ensure the oil mist adsorption effect. The electrostatic cotton is a non-woven material obtained by combing PP staple fibers, needle-punching them into a net, and then treating them with electrostatic charging. It is called electrostatic cotton because, on the one hand, the raw materials have been electrostatically treated, and on the other hand, the high dust holding capacity allows this filter material to perform filtering work stably for a longer period of time; the flame retardant layer can improve the flame retardancy and prevent the range hood from absorbing flames and causing it to spontaneously combust.

[0024] Specifically, the flame retardant layer includes an asbestos layer 3 .

[0025] Through such a design, the asbestos layer 3 has a good flame retardant effect, and at the same time, the adsorption and filtering effect of the adsorption layer should not be achieved.

[0026] Furthermore, the outer skeleton fabric layer 1 and / or the inner skeleton fabric layer 2 is provided with a flame retardant.

[0027] Through such a design, the flame retardant effect of the outer skeleton cloth layer 1 can be improved, and the flame retardant is preferably aluminum hydroxide flame retardant or the like.

[0028] Furthermore, the adsorption layer includes a meltblown cloth layer 5.

[0029] Through such a design, the oil mist adsorption effect is further improved.

[0030] Furthermore, the adsorption layer includes an activated carbon powder layer 6 .

[0031] Through such a design, the oil mist adsorption effect is further improved.

[0032] Furthermore, the flame retardant layer is arranged adjacent to the outer skeleton cloth layer 1 .

[0033] Through such a design, the flame retardant effect of the product is improved and the filter layer is prevented from contacting with high temperature and flames.

[0034] Specifically, the outer peripheries of the outer skeleton cloth layer 1 , the flame retardant layer, the adsorption layer and the inner skeleton cloth layer 2 are fixedly connected.

[0035] Through such a design, the connection between the outer skeleton fabric layer 1, the flame retardant layer, the adsorption layer and the inner skeleton fabric layer 2 is achieved.

[0036] Specifically, the outer skeleton cloth layer 1, the asbestos layer 3, the activated carbon powder layer 6, the melt-blown cloth layer 5, the electrostatic cotton layer 4, and the inner skeleton cloth layer 2 are arranged in sequence from the outside to the inside.

[0037] Through such a design, the electrostatic cotton layer 4 with the best filtering effect is placed in the innermost layer, so that the product can achieve the best filtering effect.

[0038] Specifically, the thickness of the outer skeleton cloth layer 1 is 0.35 mm, the thickness of the asbestos layer 3 is 4 mm, the thickness of the electrostatic cotton layer 4 is 2.5 mm, and the thickness of the inner skeleton cloth layer 2 is 0.35 mm.

[0039] Asbestos layer as a flame retardant material has the following outstanding effects:

[0040] High temperature resistance: Asbestos has extremely high heat resistance and heat insulation. It can maintain structural stability in high temperature environments, does not burn or melt, and can effectively prevent the spread of flames.

[0041] Good flame retardant effect: The chemical stability of asbestos fiber means that it will not continue to support combustion after the fire source is removed, thereby blocking the fire source.

[0042] Mechanical strength: Asbestos materials also have certain mechanical strength and toughness. They can be used as part of structural components. While providing flame retardant functions, they can also enhance the stability and durability of the overall structure.

[0043] The flame retardant layer may also contain the following materials:

[0044] Polymer composite materials: By adding flame retardants such as aluminum hydroxide (Al OH3), magnesium hydroxide (MgOH2), etc., composite materials can be made, which can achieve good flame retardant effects and meet environmental protection requirements.

[0045] Special coatings: The liner or other components are treated with special flame-retardant coatings, which can expand rapidly at high temperatures to form an isolation layer, preventing oxygen from contacting flammable materials, thereby inhibiting combustion.

[0046] High temperature resistant metal mesh or ceramic filter: Some high-end range hoods use high temperature resistant metal mesh or ceramic filter materials, which can not only effectively absorb grease, but also have high temperature resistance and fire resistance.

[0047] The flame retardant layer as the secondary outer layer can effectively avoid danger. Compounded with the outer skeleton cloth layer, it not only ensures safety but also further improves the flame retardant performance.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
