Negative oxygen ion emission window

Abstract

The invention discloses a negative oxygen ion emission window which comprises an emission window plate, a gold needle assembly and an insulation fixing plate. A concave part is arranged on the emission window plate, a gold needle of the gold needle assembly is arranged on the emission window plate in a penetrating manner, and the gold needle is higher than the concave part. The gold needle assembly is arranged between the insulation fixing plate and the emission window plate, and the insulation fixing plate is detachably connected with the emission window plate. The gold needle assembly is embedded in the insulation fixing plate, the insulation fixing plate is connected with the emission window plate through a bolt, and the bolt penetrates through the gold needle assembly. According to a nest-shaped structure and the groove-shaped structure gold needle emission window plate, the tip of the emission gold needle is exposed, the space at the front end of the needle tip is not blocked, negative ions do not have the inner surface absorption, and a negative ion emission effect is better. After the negative oxygen ion emission window is used for a period of time, even if dust and dirt areadsorbed on the needle tip and at the periphery, the outer surface is very convenient to scrub and clean, and the emission effect is not influenced. The space structure is further reduced by adoptingshort gold needles, the overall size of the product is reduced, the product structure is simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of negative oxygen ion emission equipment, in particular to a negative oxygen ion emission window. Background technique [0002] In the existing typical gold needle emission structure, the gold needle emission assembly is installed behind the emission window plate, and the tip of the emission gold needle is 5-10mm away from the outer surface of the emission window. The emission window has a grid or mesh structure to facilitate the emission of negative ions. Because the golden needles are inside the machine, in order to reduce the accumulation of negative ions inside the machine, a fan and air duct structure are generally installed behind the golden needle assembly to form an outward air flow to bring out the negative ions. attached Figure 9 and 10 It is a typical gold needle component structure, using long gold needles (length 15-18mm), the gold needle points are connected in series through the gold needle...

AI Technical Summary

Problems solved by technology

[0003] The existing typical structure mainly has the following disadvantages: the gold needle of the gold needle emission component is built in, and the tip of the gold needle is 5-10mm away from the surface of the emission window plate, a considerable part of the negative ions emitted is absorbed by the inner surface, and the amount of negative ions emitted to the outside is relatively reduced; due to the high-voltage negative ions It has an adsorption effect on dust in the air. After using for a period of time, a layer of dust and dirt will be absorbed around the gold needle and the surface of the emission window. Since the gold needle assembly is built-in, it is very inconvenient to clean through the emission window, especially the inner surface cannot be cleaned. , the inner surface will form a conductive layer of dust, these conductive layers will first capture the negative ions in the air, so that the number of negative ions emitted outside will be reduced

In this way, the emission effect will gradually weaken, and even the situation that it cannot be effectively emitted will appear.
