Description

Portable anion generator

Technical Field

The utility model relates to an anion generator, in particular to an anion generator with small volume and convenient carrying.

Background

The air negative ions are formed by combining oxygen molecules and water molecules in the air with free electrons, and are widely applied in the life and medical fields. Before the negative air ions react with other substances, the negative air ions can act on a human body through respiratory, nervous and blood systems, promote metabolism of the human body, stimulate the functions of endocrine glands, stimulate appetite and eliminate fatigue. In addition, the air negative ions also have the function of purifying air, can efficiently purify particulate matters such as PM2.5 and the like, remove harmful gases such as formaldehyde and the like, and kill microorganisms such as bacteria, viruses and the like.

Chinese patent application CN200920133289.9 discloses a portable anion generator, which comprises a housing, a power connection terminal fixed at one end of the housing, and an anion generator body fixed inside the housing; the power input end of the negative ion generator body is connected with the power connection terminal in a circuit mode, and the shell is provided with through holes on at least one side face of the shell corresponding to the discharge needles of the negative ion generator body. The negative ion generator has the advantage of convenient carrying, but the discharge needle (negative ion emitting head) is arranged in the shell, so that the generated air negative ions are difficult to be quickly released to the surrounding environment, and are easy to be adsorbed by the shell due to the charge, thereby causing the defect of low negative ion release efficiency.

In order to solve the above problems, one of the common solutions is to provide a fan inside the anion generator, and the fan can quickly blow out air rich in air anions inside the housing to the surrounding environment, so as to reduce the adsorption of the housing on the air anions. For example, chinese patent application CN201220541196.1 discloses a portable anion air purifier, which comprises a casing, an anion generating module and a fan, wherein the anion generating module and the fan are disposed in the casing, an anion outlet is disposed on the casing, and a distance between the anion outlet and an anion emitting head is 3-5 mm. The negative ion generator has the advantages that negative ions are less adsorbed by the machine shell and the releasing efficiency is high, but the arrangement of the fan enables the negative ion generator to generate noise in the operation process, and the negative ion generator causes interference to users in certain environmental conditions such as night rest and the like.

Of course, the anion emission head can also be arranged outside the shell of the anion generator, so that the problem of fan noise is solved without arranging a fan. For example, chinese patent application CN201410617903.4 discloses a portable negative ion purifier, which extends a discharge brush (negative ion emission head) outside a housing, so as to create a clean and healthy local microenvironment without using the power of a fan. Such a problem is that the negative ion emitting head is exposed to the external environment for a long time, which easily causes damage (e.g., falling, collision and damage) of the negative ion emitting head and a decrease in efficiency due to adsorption of contaminants and the like.
