Description

Technical Field

[0001] The present application relates to the field of air filtration, and in particular to a carbon fiber cloth filter box. Background Art

[0002] Currently, when operators are working in a space with toxic or harmful gases or a lot of dust, they usually wear a filter mask to filter the inhaled gas. The filter mask can effectively remove harmful substances in the air.

[0003] Existing filtering masks often have a filter box that is easy to disassemble. Fillers mainly composed of activated carbon particles are placed in the filter box. Harmful substances are adsorbed through the fine pores of the activated carbon particles, thereby achieving removal of the harmful substances.

[0004] Regarding the above-mentioned related technologies, the activated carbon particles have fine pores on the central hole walls but the outer surface is relatively smooth and the adsorption effect is poor. There are still large gaps between the activated carbon particles. When the activated carbon particles adsorb harmful substances, due to the short residence time of the air in the filter box, there is still a small amount of air carrying harmful substances entering the wearer's body through the gaps between the activated carbon particles. Utility Model Content

[0005] In order to increase the time that air remains in the filter box and thus increase the filter box's adsorption effect on harmful substances, the present application provides a carbon fiber cloth filter box.

[0006] The present application provides a carbon fiber cloth filter box, which adopts the following technical solution:

[0007] A carbon fiber cloth filter box comprises a box body, characterized in that: the box body is provided with an air inlet and an air outlet, a filter layer is arranged inside the box body, the filter layers are arranged in sequence from the air inlet to the air outlet, the outer edge of the filter layer abuts against the inner wall of the box body, a support frame is provided inside the box body, a buffer space is provided between the support frame and the filter layer, and the outer wall of the support frame abuts against the inner wall of the box body.

[0008] By adopting the above technical solution, after the air enters the box body through the air inlet, the air is adsorbed and filtered by each filter layer. When the air enters the box body, the support frame supports the filter layer inside the box body, so that the air flow rate when the air enters the buffer space is effectively reduced, and the contact between the air and the filter layer is more complete, which effectively improves the filtering effect of the filter box.

[0009] Optionally, the filter layer includes a non-woven fabric layer, a carbon fiber fabric layer and a meltblown fabric layer, the supporting frame is located between the non-woven fabric layer and the carbon fiber fabric layer, a connecting portion is provided at the edge of the non-woven fabric layer, the box body is provided with a boss protruding toward the inside of the box body, the boss abuts against the connecting portion, and an air intake space is provided between the non-woven fabric layer and the air intake portion.

[0010] By adopting the above technical solution, an air intake space is opened between the non-woven fabric layer and the air intake part. When air enters the box body, it first fills the air intake space, and then enters the non-woven fabric layer from the air intake space, so that the filtered air enters the non-woven fabric layer evenly, effectively improving the filtering effect of the non-woven fabric layer.

[0011] Optionally, the box body comprises an upper box cover and a lower box cover, the upper box cover is provided with a plurality of card blocks on the inner side, and the lower box cover is provided with card slots corresponding to the card blocks one by one.

[0012] By adopting the above technical solution, the buckle of the upper box cover is inserted into the slot of the lower box cover to achieve a detachable connection of the box body. When it is necessary to replace the components inside the box body, the buckle of the upper box cover is removed from the slot and the box body is opened to replace the components, which is convenient for users to replace the components inside the box body.

[0013] Optionally, the air inlet is arranged on one side of the upper box cover, and the air outlet is located on a side of the lower box cover away from the air inlet.

[0014] By adopting the above technical solution, the air inlet and the air outlet are arranged as far apart as possible, so that the air passes through the filter layer obliquely when passing through the inside of the box body, which effectively improves the filtering effect of the filter box.

[0015] Optionally, a plurality of support plates for fixing the filter layer are provided on the inner side of the lower box cover, and air outlet grooves are provided between the support plates, and the air outlet grooves are connected to the air outlet part.

[0016] By adopting the above technical solution, the filter layer is supported by the support plate. After the air passes through the filter layer, it is discharged from the air outlet through the air outlet grooves between the support plates. Therefore, the filtered air not only passes through the non-woven fabric layer at the air outlet, but also effectively improves the filtering effect of the meltblown fabric layer.

[0017] Optionally, the nonwoven fabric layer comprises an active enzyme layer.

[0018] By adopting the above technical solution, when the air to be filtered passes through the non-woven fabric layer, the active enzyme layer can effectively decompose some toxic substances in the air, thereby effectively improving the filtering effect of the non-woven fabric layer.

[0019] Optionally, the box body width gradually decreases from the air inlet to the air outlet.

[0020] By adopting the above technical solution, since the filter box is connected to the filter mask through the air outlet part, the box body at the air outlet part is smaller, which can avoid blocking the user's vision as much as possible during use, effectively improving the user's wearing experience.

[0021] Optionally, two groups of filter layers are symmetrically arranged, and the filter layers are sequentially provided with a non-woven fabric layer, a meltblown fabric layer, an electrostatic cotton layer and a carbon fiber fabric layer, and the supporting frame is located between the two carbon fiber fabric layers.

[0022] By adopting the above technical solution, the air is filtered layer by layer as it passes through the non-woven fabric layer, the meltblown fabric layer, the electrostatic cotton layer and the carbon fiber fabric layer in sequence. Since the filter layers are symmetrically arranged in two groups, the area of ​​air entering the filter box from the outside is effectively increased.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. After the air enters the box through the air inlet, it is adsorbed and filtered by each filter layer. When the air enters the box, the support frame supports the filter layer inside the box, so that the air flow rate when the air enters the buffer space is effectively reduced, so that the air and the filter layer are in more contact, which effectively improves the filtering effect of the filter box;

[0025] 2. Use a support frame to press the filter layer inside the box body, thereby forming a buffer space between the non-woven fabric layer and the carbon fiber fabric layer. When the air passes through the non-woven fabric layer and enters the buffer space, the flow rate will decrease and fill the buffer space, so that the harmful substances in the air can more fully contact with the carbon fiber fibers, effectively improving the filtering effect of the carbon fiber fabric layer.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] The embodiment of the present application discloses a carbon fiber cloth filter box.

[0035] Embodiment 1:

[0036] Reference Figure 1 and Figure 2 After passing through the non-woven fabric layer 21, the air enters the buffer space 5 formed by the support frame 3, the non-woven fabric layer 21 and the carbon fiber fabric layer 22. When the air enters the buffer space 5, the flow rate of the gas will slow down and fill the entire buffer space 5, so that the contact area between the air and the carbon fiber fabric layer 22 behind is significantly increased. At the same time, the support frame 3 also has a good fixing effect on the filter layer 2, pressing the filter layer 2 against the inner wall of the box body 1.

[0037] Reference Figure 1 and Figure 2 A carbon fiber cloth filter box includes a box body 1, and an air inlet 111 is provided on one side of the box body 1, and an air outlet 121 is provided on the side of the box body 1 away from the air inlet 111. A filter layer 2 composed of a non-woven fabric layer 21, a carbon fiber cloth layer 22 and a melt-blown cloth layer 23 is placed inside the box body 1, and the outer edge of the filter layer 2 abuts against the inner wall of the box body 1. Air enters the box body 1 through the air inlet 111, and is discharged through the air outlet 121 after being filtered by the filter layer 2. The carbon fiber cloth layer 22 has a high adsorption effect on toxic gases, so that the filter box has a high use efficiency.

[0038] Reference Figure 2 and Figure 3, a connection portion is provided at the edge of the non-woven fabric layer 21, and is connected to the boss 113 inside the box body 1 through the connection portion. An air intake space 4 is provided between the non-woven fabric layer 21 and the box body 1. The connection between the connection portion and the boss 113 effectively increases the contact area between the non-woven fabric layer 21 and the box body 1, and an air intake space 4 is left between the non-woven fabric layer 21 and the box body 1. When the air to be filtered enters the box body 1, it first fills the air intake space 4, and then evenly enters the non-woven fabric layer 21 from the air intake space 4. The non-woven fabric layer 21 has a good filtering effect on dust and particles. By setting the air intake space 4, the contact area between the non-woven fabric layer 21 and the non-woven fabric layer 21 is increased, so that the non-woven fabric layer 21 can better block and isolate larger particles in the air, thereby achieving preliminary filtration of the air.

[0039] Reference Figure 2 The non-woven fabric layer 21 includes an active enzyme layer. In this embodiment, the formed non-woven fabric layer 21 is immersed in a liquid filled with active enzymes, and then the non-woven fabric layer 21 is dried to complete the processing and manufacturing of the active enzyme layer. When the air to be filtered passes through the non-woven fabric layer 21, the active enzyme can decompose some of the toxic substances therein. Compared with the ordinary non-woven fabric layer 21 without the active enzyme layer, the non-woven fabric layer 21 in this embodiment has a better filtering ability.

[0040] Reference Figure 2 and Figure 3 The air passing through the buffer space 5 contacts the carbon fiber cloth layer 22, which is composed of several layers of carbon fiber cloth woven from carbon fiber filaments. Compared with the traditional filter box filled with carbon fiber particles, the gaps between the carbon fiber cloth layers 22 are smaller, so the carbon fiber cloth layer 22 has a better adsorption effect on toxic substances in the air. In addition, the carbon fiber cloth layer 22 is lighter, so the burden on the user is relatively small.

[0041] Reference Figure 2 After passing through the carbon fiber cloth, the air contacts with the meltblown cloth layer 23, and the meltblown cloth layer 23 finally adsorbs a small amount of toxic substances that have not been adsorbed after passing through the carbon fiber cloth layer 22, and further filters the air passing through the filter box, so that the filtering effect of the filter box is further improved.

[0042] Reference Figure 3 In order to facilitate the disassembly and assembly of the box body 1 and the replacement of the filter layer 2 in the filter box by the wearer, the box body 1 is divided into an upper box cover 11 and a lower box cover 12. A buckle 112 is installed at the inner edge of the upper box cover 11, and a slot 124 for the buckle 112 to be engaged is provided in the lower box body 1, thereby achieving the engagement between the upper box cover 11 and the lower box cover 12. The wearer can easily replace the filter layer 2 inside without the help of tools.

[0043] Reference Figure 2 In this embodiment, the air inlet 111 is arranged on one side of the upper end cover, and the air outlet 121 is installed on the side of the lower end cover away from the air inlet 111. In this arrangement, the air inlet 111 and the air outlet 121 are placed and installed as far as possible, so that when the air enters the box body 1 through the air inlet 111, the overall movement path is inclined from the air inlet 111 to the air outlet 121, so that the air passing through the filter box passes through the filter layer 2 as evenly as possible, so that the filtering effect of the filter box is effectively improved.

[0044] Reference Figure 2 In order to improve the utilization efficiency of the carbon fiber cloth layer 22 and the meltblown cloth layer 23, a plurality of support plates 122 are arranged on the inner side of the lower box cover 12, and the filter layer 2 is supported by the support plates 122, and a plurality of air outlet grooves 123 are provided between the support plates 122, and the air outlet grooves 123 are connected to the air outlet portion 121. If the air outlet grooves 123 are not provided, the air is discharged from the box body 1 only through the contact point between the meltblown cloth layer 23 and the air outlet portion 121, so that the utilization efficiency of the meltblown cloth layer 23 and the carbon fiber cloth layer 22 is low. After the support plates 122 and the air outlet grooves 123 are provided, the air passing through the box body 1 can enter the air outlet grooves 123 after evenly passing through the carbon fiber cloth layer 22 and the meltblown cloth layer 23, which effectively improves the filtering effect of the meltblown cloth layer 23.

[0045] Reference Figure 2 In this embodiment, the width of the box body 1 is preferably gradually reduced from the air inlet 111 to the air outlet 121. When the wearer installs the filter box on the filter mask, the smaller width portion is closer to the front of the wearer. When the wearer uses the filter box, the wearer's vision is not blocked as much as possible, which is convenient for the wearer to perform labor operations and improve the wearer's wearing experience.

[0046] Embodiment 2:

[0047] Reference Figure 4 and Figure 5 The biggest difference between this embodiment and the first embodiment is that, since two filter layers 2 are provided, when air enters the box body 1 from the outside, the air intake area is effectively expanded, so that the air intake portion 111 is the majority of the surface of the box body 1.

[0048] Reference Figure 5 and Figure 6When the unfiltered air passes through the non-woven fabric layer 21, the melt-blown fabric layer 23, the electrostatic cotton layer 24 and the carbon fiber fabric layer 22 in sequence, after being filtered by the first few layers, the carbon fiber fabric layer 22 performs the final adsorption on the air. Since a support frame 3 is installed between the two filter layers 2, the flow rate of the air after entering between the two carbon fiber fabric layers 22 is controlled and reduced. Due to the reduced air flow rate, the residence time of the air between the two carbon fibers is effectively extended, thereby effectively improving the adsorption efficiency of the filter box.

[0049] The implementation principle of a carbon fiber cloth filter box in the embodiment of the present application is as follows: by installing a carbon fiber cloth layer 22 in the filter box instead of carbon fiber particles to adsorb harmful substances in the air, the filtering effect of the filter box is improved, and due to its light weight, a buffer space 5 is formed inside the box body 1 through the supporting frame 3, so that the flow rate of air entering the buffer space 5 will be greatly reduced, so that the contact time between the air and the internal filter layer 2 is effectively increased, so that the filtering effect is greatly enhanced.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
