Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to an air purification filter layer and an air purifier. Background Technology

[0002] Given the growing concern about air pollution, the performance of the filter layer in air purifiers is crucial as an important device for improving indoor air quality.

[0003] Traditional air purifier filter layers generally suffer from a significant technical problem: the fixation of adsorbed particles (such as carbon particles) is not stable and secure enough. During air purifier operation, the constant impact of airflow on the filter layer, or the shaking of the device during movement or daily use, can easily cause adsorbed particles to detach from the filter layer. These detached particles can then re-diffuse into the indoor environment with the air circulation, causing secondary pollution. This contradicts the original purpose of air purifiers and greatly affects their purification effect and overall performance. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides an air purification filter layer and an air purifier, which can effectively solve the problems existing in the prior art.

[0005] The technical solution of this utility model is:

[0006] According to one aspect of the present invention, the filter element comprises: a mesh fabric and a filter element, wherein the mesh fabric is sealed and wrapped around the outside of the filter element; the filter element comprises a mesh matrix and adsorption particles, wherein a plurality of adsorption particles for adsorbing pollutants are distributed on the surface of the mesh matrix; and the pore size of the mesh fabric is smaller than the pore size of the mesh matrix.

[0007] Furthermore, at least one side of the mesh substrate is coated with environmentally friendly pressure-sensitive adhesive, and several of the adsorbent particles are adhered to the mesh substrate by the environmentally friendly pressure-sensitive adhesive.

[0008] Furthermore, the mesh substrate is a rhomboid mesh, the aperture of the rhomboid mesh is 0.8-2cm, and the width of the ribs of the rhomboid mesh is 0.1-0.4cm.

[0009] Furthermore, the adsorbent particles are at least one of activated carbon particles, molecular sieves, or zeolites.

[0010] Furthermore, the mesh fabric has at least one first sewing part at the position corresponding to the hole of the mesh substrate, and the two sides of the mesh fabric are sewn together to form the first sewing part, so that the filter element is fixed inside the mesh fabric.

[0011] Furthermore, the mesh fabric is provided with a second sewing part for sealing at both the upper and lower ends.

[0012] Furthermore, the mesh size is 0.05–0.15 cm.

[0013] According to another aspect of the present invention, an air purifier includes an air purification filter layer as described above, the air purification filter layer being detachably installed inside the air purifier.

[0014] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0015] Firstly, the mesh fabric wrapped around the filter element has pores smaller than the size of the adsorbed particles, effectively preventing particles such as activated carbon particles and molecular sieves from desorbing from the filter element. Even under airflow impact or equipment vibration, adsorbed particles cannot pass through the mesh fabric, thus avoiding secondary pollution. The mesh fabric provides external support for the filter element, enhancing the mechanical strength of the entire filter layer. During the operation of the air purifier, the mesh fabric prevents the filter element from deforming or being damaged by airflow impact, extending the filter element's service life.

[0016] Secondly, during the movement or shifting of the filter element, adsorbed particles on the mesh substrate may fall off. By sewing the mesh fabric at the corresponding mesh substrate holes, the filter element is firmly fixed inside the mesh fabric, ensuring that the filter element is always in the optimal working position and improving the filtration effect.

It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] like Figures 1 to 6 As shown, this solution provides an air purification filter layer and an air purifier.

[0027] Please see Figures 1 to 5 The filter element comprises a mesh fabric 1 and a filter cartridge 2, with the mesh fabric 1 sealingly wrapped around the filter cartridge 2. The pore size of the mesh fabric 1 is 0.05–0.15 cm. Preferably, the pore size of the mesh fabric 1 is 0.09–0.11 cm. The filter cartridge 2 comprises a mesh substrate 21 and adsorbent particles 22, with the pore size of the mesh fabric 1 being smaller than that of the mesh substrate 21. The mesh substrate 21 is a rhombic mesh with a pore size of 0.8–2 cm, preferably 1–1.3 cm; the width of the ribs in the rhombic mesh is 0.1–0.4 cm. Preferably, the width of the ribs in the rhombic mesh is 0.1–0.15 cm. The adsorbent particles 22 are at least one of activated carbon particles, molecular sieves, or zeolites. Preferably, in this embodiment, the adsorbent particles 22 are activated carbon particles. The mesh fabric 1, wrapped around the filter cartridge 2, has a pore size smaller than that of the adsorbent particles, effectively preventing adsorbent particles such as activated carbon particles and molecular sieves from desorbing from the filter cartridge. Even under airflow impact or equipment shaking, adsorbed particles 22 cannot pass through the mesh fabric 1, thus avoiding secondary pollution. The mesh fabric 1 provides external support for the filter element 2, enhancing the mechanical strength of the entire filter element layer. During the operation of the air purifier (not shown), the mesh fabric 1 can prevent the filter element 2 from deforming or being damaged by airflow impact, extending the service life of the filter element 2.

[0028] Please see Figures 1 to 5The surface of the mesh substrate 21 is distributed with a number of adsorption particles 22 for adsorbing pollutants. Specifically, at least one side of the mesh substrate 21 is coated with an environmentally friendly pressure-sensitive adhesive (not shown in the figure), and the adsorption particles 22 are adhered to the mesh substrate 21 by the environmentally friendly pressure-sensitive adhesive. Of course, in order to increase the effective adsorption area of ​​the filter element 2, environmentally friendly pressure-sensitive adhesive can be coated on both sides of the mesh substrate 21 to increase the number of adsorption particles 22.

[0029] Please see Figures 1 to 6 The mesh fabric 1 has at least one first sewing part 11 at the position corresponding to the hole 111 of the mesh substrate 21. The two sides of the mesh fabric 1 are sewn together to form the first sewing part 11, thus fixing the filter element 2 inside the mesh fabric 1. Preferably, multiple first sewing parts 11 are provided at the positions of the holes 111 of the mesh substrate 21 to further improve the stability of the filter element 2. During the movement or displacement of the filter element 2, adsorbed particles 22 on the mesh substrate 21 may fall off. By sewing the mesh fabric 1 at the positions corresponding to the holes of the mesh substrate 21, the filter element 2 is firmly fixed inside the mesh fabric, ensuring that the filter element is always in the optimal working position and improving the filtration effect. Second sewing parts 3 for sealing are provided at both the upper and lower ends of the mesh fabric 1.

[0030] According to another aspect of the present invention, an air purifier includes an air purification filter layer as described above, the air purification filter layer being detachably installed inside the air purifier.
