Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of air purification, and more specifically, to a graphene air purifier filter. Background Technology
[0002] Indoor air purifiers play an important role in modern life. They help improve indoor air quality and protect people's respiratory health. Air purifiers can capture and remove various pollutants in the air, such as dust, pollen, bacteria, viruses, formaldehyde, and other harmful substances. The filter is the core component of an air purifier. During use, the filter will gradually become saturated and lose its filtering capacity. If it is not replaced in time, the saturated filter will not only be unable to filter harmful substances, but may also become a breeding ground for bacteria and mold, leading to secondary pollution.
[0003] Currently, the filter element and the support frame are tightly connected, making it difficult to replace only the filter element. The entire support frame needs to be replaced, resulting in high replacement costs for air filters. Most current filter elements are made of cotton or paper, which have good filtration effects but are not very effective at adsorbing odors and common harmful gases. Therefore, we propose a graphene air purifier filter element. Utility Model Content
[0004] In view of the above-mentioned technical problems in related technologies, this utility model provides a graphene air purifier filter element that can solve the above problems.
[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:
[0006] A graphene air purifier filter element includes an inner purification cylinder, an air supply pipe connected to the bottom of the inner purification cylinder, a porous arc-shaped hollow shell detachably installed on the outer circumference of the inner purification cylinder, and a graphene composite filter element embedded inside the porous arc-shaped hollow shell. A column is fixedly installed at the top of the inner purification cylinder, and a circular cover for limiting the position of the top of the porous arc-shaped hollow shell is embedded in the column. A spring and a clamp are arranged sequentially from bottom to top on the top of the column.
[0007] Furthermore, the graphene composite filter element includes an outer layer of activated carbon and an inner layer of graphene, with several honeycomb-shaped pores formed on the surface of the outer activated carbon layer.
[0008] Furthermore, the porous arc-shaped hollow shell has several flow guide holes on both its front and rear surfaces, and an arc-shaped retaining strip is provided at the bottom of the porous arc-shaped hollow shell.
[0009] Furthermore, an annular seat is integrally formed at the bottom outer circle of the purification inner cylinder, and arc-shaped grooves are opened on both sides of the annular seat to accommodate the arc-shaped clips.
[0010] Furthermore, the outer circular surface of the purification inner cylinder is provided with several ventilation holes, and the front and rear sides of the outer circular surface of the purification inner cylinder are integrally formed with spacer strips. The two vertical end faces of the porous arc-shaped hollow shell are respectively in contact with the vertical faces of the two spacer strips on the same side.
[0011] Furthermore, a concave annular groove is provided at the top of the column, and the clamp is engaged inside the concave annular groove.
[0012] Furthermore, a through hole with the same diameter as the column is opened in the middle of the circular cover, and the top of the porous arc-shaped hollow shell is flush with the top of the purification inner cylinder. The top of the porous arc-shaped hollow shell is embedded inside the circular cover.
[0013] The beneficial effects of this utility model are as follows: The graphene composite filter element of this application device is integrated on a porous arc-shaped hollow shell. The porous arc-shaped hollow shell is installed on the outside of the purification inner cylinder through a snap-fit structure, which simplifies the steps of replacing the graphene composite filter element. Only by lifting the circular cover can the porous arc-shaped hollow shell be disassembled and the graphene composite filter element taken out for replacement. Moreover, the bottom of the porous arc-shaped hollow shell is snapped in place and the top is restricted by the circular cover, which ensures the stability of the installation. This structure simplifies the operation of partially replacing the core structure of the filter element and optimizes the user experience.
[0014] An activated carbon outer layer is added to the graphene filter. The activated carbon can adsorb common harmful gases and odors, which can help the graphene filter improve the air purification quality. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0024] like Figure 1-4 As shown, this utility model discloses a graphene air purifier filter element, including an inner purification cylinder 9, an air supply pipe 7 connected to the bottom of the inner purification cylinder 9, a porous arc-shaped hollow shell 5 detachably installed on the outer circumference of the inner purification cylinder 9, and a graphene composite filter element 8 embedded inside the porous arc-shaped hollow shell 5. A column 2 is fixedly installed at the top of the inner purification cylinder 9, and a circular cover 1 for limiting the position of the top of the porous arc-shaped hollow shell 5 is embedded in the column 2. A spring 3 and a clamp 4 are arranged sequentially from bottom to top on the top of the column 2. The graphene composite filter element 8 includes an activated carbon outer layer 801 and a graphene inner layer 802. The surface of the activated carbon outer layer 801 is provided with a number of honeycomb-shaped pores. The graphene inner layer 802 is composed of graphene loaded with a catalyst sprayed on the surface of a filter sponge, and then the sponge is dried to form a graphene filter layer.
[0025] Example 1: The skeleton components, including the circular cover 1, column 2, porous arc-shaped hollow shell 5, spacer strip 6, purification inner cylinder 9, and annular seat 10, are made of PET plastic.
[0026] The graphene inner layer 802 is composed of graphene loaded with catalyst sprayed onto the surface of the filter sponge, and then the sponge is dried to form a graphene filter layer. Semiconductor photocatalytic materials such as Ta2O5, ZnO, and TiO2 can be used to significantly improve photocatalytic performance. Under light conditions, these composite materials can reduce harmful gases (such as CO and CO2) to hydrocarbons such as methanol (CH3OH) or directly convert them into carbon dioxide. The activated carbon outer layer 801 and the graphene inner layer 802 are bonded together by physical pressing and placed in the inner cavity of the porous arc-shaped hollow shell 5.
[0027] The installation steps for the above components are as follows: Install the graphene composite filter element 8 into the porous arc-shaped hollow housing 5. The arc-shaped retaining strip at the bottom of the porous arc-shaped hollow housing 5 cooperates with the arc-shaped groove 1001 of the annular seat 10. The circular cover 1 cooperates with the column 2. Install the spring 3 and the clamp 4 in sequence. When the circular cover 1 is raised, the spring 3 is compressed. Under normal circumstances, the circular cover 1 is fitted outside the top of the porous arc-shaped hollow housing 5 and the purification inner cylinder 9. When removing and replacing the graphene composite filter element 8, it is only necessary to raise the circular cover 1 so that the arc-shaped retaining strip at the bottom of the porous arc-shaped hollow housing 5 can separate from the arc-shaped groove 1001 of the annular seat 10. The graphene composite filter element 8 can be easily replaced by removing the porous arc-shaped hollow housing 5.
[0028] In the preferred technical solution, the porous arc-shaped hollow shell 5 has several guide holes 501 on both the front and rear surfaces. The guide holes 501 are used for airflow to pass through the porous arc-shaped hollow shell 5. The bottom of the porous arc-shaped hollow shell 5 is provided with an arc-shaped retaining strip. The bottom outer circle of the purification inner cylinder 9 is integrally formed with an annular seat 10. Both sides of the annular seat 10 are provided with arc-shaped grooves 1001 to accommodate the arc-shaped retaining strip. The bottom of the porous arc-shaped hollow shell 5 is engaged with the annular seat 10. With the help of the circular cover 1, the porous arc-shaped hollow shell 5 can be stably installed.
[0029] In the preferred technical solution, a number of ventilation holes 901 are opened on the outer circular surface of the purification inner cylinder 9, and spacer strips 6 are integrally formed on the front and rear sides of the outer circular surface of the purification inner cylinder 9. The two vertical end faces of the porous arc-shaped hollow shell 5 are respectively in contact with the vertical faces of the two spacer strips 6 on the same side.
[0030] In the preferred technical solution, a concave annular groove 201 is provided at the top of the column 2, and the clamp 4 is engaged inside the concave annular groove 201. The clamp 4 is used to limit the spring 3 and realize the elastic movement of the circular cover 1.
[0031] In the preferred technical solution, the circular cover 1 has a through hole in the middle that is the same diameter as the column 2. The top of the porous arc-shaped hollow shell 5 is flush with the top of the purification inner cylinder 9. The top of the porous arc-shaped hollow shell 5 is embedded inside the circular cover 1. When the circular cover 1 is raised, the spring 3 is compressed. When the circular cover 1 is released, the spring 3 rebounds to reset it.
[0032] In practical use, the air supply pipe 7 is connected to the input end of the fan. Therefore, the adsorbed unpurified airflow passes through the guide hole 501 of the porous arc-shaped hollow shell 5, the graphene composite filter element 8, the vent hole 901, and enters the purification inner cylinder 9. Then, the purified gas is output from the air supply pipe 7 and the fan. When the device is placed indoors, it can continuously purify the indoor air.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
