Negative ion lamp

Abstract

The anion lamp comprises a shell assembly, a light source assembly and an anion generating assembly, the light source assembly and the anion generating assembly are both arranged on the shell assembly, anion releasing holes are formed in the shell assembly, and the anion generating assembly comprises an anion releaser capable of releasing anions. The negative ion releaser is arranged in the negative ion release hole, and the tail end of the negative ion releaser protrudes out of the outer side of the negative ion release hole. As the tail end of the negative ion releaser protrudes out of the outer side of the negative ion releasing hole and is exposed to the outside air, when the negative ion releaser releases negative ions, the negative ions can be directly released to the outside air, and compared with an existing negative ion releaser with the tail end shrunk in the releasing hole, the negative ion releasing effect is better. According to the scheme, the negative ions do not need to be released in the negative ion release holes and then discharged to the outside, so that the concentration of the negative ions released to the outside air can be improved, and the air purification efficiency is improved.

Description

Technical Field

[0002] Negative ion generators and emitters can produce negative ions to purify the air. Commonly used emitters are carbon brushes or metal needles. Some existing lamps have also incorporated negative ion air purification structures and functions. However, the negative ion emitters in existing lamps are typically configured with their ends retracted inside a release hole in the lamp housing. Negative ions are first released inside the release hole and then released outward from the hole. This results in a low concentration of released negative ions and low air purification efficiency.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0033] It should be noted that if the embodiments of the present invention involve directional indications, such as up, down, left, right, front, and back, the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features.

The light source component and the negative ion generating component are both arranged on the shell component. The shell component is provided with a negative ion release hole 1221.

The negative ion releaser 31 is arranged in the negative ion release hole 1221, and the end of the negative ion releaser 31 protrudes from the outside of the negative ion release hole 1221.

[0036] Since the end of the negative ion releaser 31 protrudes from the outside of the negative ion release hole 1221, the end of the negative ion releaser 31 is exposed to the external air. Therefore, when the negative ion releaser 31 releases negative ions, the negative ions can be directly released into the external air. Compared with the existing negative ion releaser 31 in which the end is retracted into the release hole, in this solution, the negative ions do not need to be released into the negative ion release hole 1221 first and then discharged to the outside, thereby increasing the concentration of negative ions released into the external air and improving the air purification efficiency.
