Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a positive and negative ion air purification filter element module. Background Art

[0002] In air purification systems, common filter elements are composed of filter screens and high-pressure positive and negative ion generating modules, which respectively achieve the effects of dust filtration and sterilization. They are usually installed relatively independently, and the required installation structure occupies a large space inside the pipeline. In addition, since the ion concentration is only higher near the generating module, in some systems, an air guide structure is also provided on the front side of the filter element structure to guide air to the ion generating module to promote the diffusion of ions. However, the installation of the air guide structure further increases the wind resistance inside the pipeline, resulting in reduced ventilation efficiency. Summary of the invention

[0005] Furthermore, the windward surface of the device body is configured with protrusions and grooves that are alternately spaced, the protrusions are provided with the release port, and the groove area is configured as the filter block.

[0006] Furthermore, the ion emission end is provided with a plurality of carbon brush electrodes, and the plurality of carbon brush electrodes are aligned and arranged at the top of the protrusion.

[0007] Furthermore, the filter block is provided with a plurality of filter holes evenly distributed on the inner groove surface of the groove.

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Attached Figure 1 This is a schematic diagram of the cross-sectional structure of an embodiment of the utility model;

[0012] Attached Figure 2 The utility model is a cross-sectional schematic diagram of an embodiment of the utility model located at a protrusion in a ventilation duct. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] As attached Figure 1-2 The positive and negative ion air purification filter element module comprises a device body 1 with an integrated wind guide structure; a plurality of filter blocks 2 are arranged at intervals on the device body 1, and a purification unit 3 is arranged between adjacent filter blocks 2; the purification unit 3 comprises an ion generating module 31 located on the leeward side of the device body 1, the ion emitting end 32 of the ion generating module 31 is arranged to face the wind, and the device body 1 is provided with a release port corresponding to the ion emitting end 32.

[0015] This solution integrates the air guide structure, filter element and positive and negative ion generator into a product that combines air filtration and purification. It can be directly installed in the ventilation duct that requires air purification and filtration. After integration, it has high integrity and is easy to install. There is no need to install the positive and negative ion generator through an additional bracket, nor is there any need to install an additional air guide plate to increase the diffusion of ions. It occupies little space in the duct, thereby reducing wind resistance, improving ventilation efficiency, and enhancing purification effect.

[0016] The windward surface of the device body 1 is provided with alternately spaced protrusions 11 and grooves 12, the protrusion 11 is provided with the release port, and the groove 12 area is provided as the filter block 2. The ion release port is provided at the top position of the protrusion, and the inclined surface where the protrusion transitions to the groove position forms a wind guide surface, and the wind blowing toward the protrusion surface is split to both sides, dispersing and carrying the ion cloud to diffuse toward the filter block, so that the airflow completes automatic dust removal and sterilization when passing through the filter block, achieving a better filtering and purification effect.

[0017] The ion emission end 32 is provided with a plurality of carbon brush electrodes 33, and a plurality of the carbon brush electrodes 33 are aligned and arranged at the top of the protrusion 11, and a plurality of equidistant electrodes are arranged equidistantly, so that the generated ion cloud is evenly distributed around the release port, and after being diffused by the wind, the ion distribution is more even, and the purification effect is stronger.

[0018] The filter block 2 is provided with a plurality of filter holes evenly distributed on the inner groove surface of the groove 12, forming a concave filter screen structure located on the windward side. The concave curved surface can increase the opening area, allowing more filter holes to be opened, thereby increasing the ventilation volume and improving the ventilation efficiency.

[0019] Preferably, the protrusion 11 and the groove 12 are both strip structures and are arranged vertically. The device body can be directly made of metal plates, and filter holes are evenly opened on the surface of the metal plates to form a filter structure. The filter structure is bent multiple times to form a corrugated filter structure, and an ion generating module is installed in the concave part of the leeward side of the corrugated filter structure. The circuit part of the ion generating module is composed of an integrated PCB board, and multiple carbon brush electrodes are directly welded to one side of the circuit board, so that the area occupied by the release port is smaller and the area of ​​the relative filter block is larger, thereby obtaining better ventilation efficiency.

[0020] The device body 1 is tilted in the ventilation duct, and its windward surface is tilted downward. Preferably, the device body is installed on the inner wall of the ventilation duct through an elastic member, and the gap is dust-proofed with common dust-proof measures such as dust-proof cloth. The elastic member can be an elastic sheet. After ventilation, under the action of the elastic member, the device body as a whole will shake slightly, thereby preventing dust from being adsorbed and accumulated on the filter surface for a long time. The multi-groove wind guide structure can guide part of the airflow to flow along the groove direction, so that the dust on the filter surface is blown down to the bottom of the duct along the groove direction, effectively avoiding the blockage of the filter holes and the release port on the windward side, maintaining a good purification and filtration effect for a long time, and ensuring a good ventilation effect.

[0021] The above are only preferred embodiments 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 principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
