Problems solved by technology

[0005] 2. The negative ion generator itself is faulty, for example, its discharge tip is damaged, etc.
But when, when the second situation occurs, the negative ion generator will not work properly all the time
[0007] However, the existing negative ion generators do not have abnormal detection and processing functions. When abnormal discharges occur, the negative ion generators usually still work and consume power, but they no longer generate negative ions, and users cannot clearly know it. It is inconvenient to quickly eliminate its own failure

Embodiment 1

[0030] This embodiment discloses a detection method in the normal detection mode, and its corresponding circuit principle structure block diagram is as follows figure 2 As shown, the specific cycle execution steps of this mode are as follows figure 1 Shown:

[0031] Step1A: The main controller constantly monitors the abnormal discharge of the negative ion generator; specifically, it can be interrupted by abnormality or scanning from time to time; the abnormal interruption is: once the negative ion generator is abnormal, it actively transmits an interrupt request to the main controller to notify the main controller to perform follow-up actions; the scanning at all times is: the main controller continuously reads the working conditions of the negative ion generator; if the negative ion generator has an abnormal discharge, execute Step2A and subsequent steps, such as negative ion generation If there is no abnormal discharge of the counter, execute Step2B and subsequent counter ...

Embodiment 2

[0045]In this embodiment, on the basis of Embodiment 1, a service and maintenance detection mode is added. In actual operation, you can switch between the two through an infrared remote control, and set a receiver for receiving infrared codes in the main controller. Once the receiver receives the code of the maintenance detection mode, the main controller will enter the service maintenance detection mode , further rapid detection and troubleshooting, the specific steps of this mode are as follows image 3 Shown:

[0046] Step1C: The main controller continuously detects whether there is an abnormal discharge of the negative ion generator (specifically, it can be abnormally interrupted or scanned from time to time). If it detects that the negative ion generator has abnormal discharge, the steps after Step2C will be executed sequentially;

[0047] Step2C: The main controller sends a shutdown signal to the negative ion generator to turn off the power of the negative ion generator...

Abstract

The invention belongs to the technical field of negative ion generators and specifically discloses a detection method of abnormal discharge of the negative ion generator. The detection method comprises the following steps of: stopping the negative ion generator in an abnormal and active manner, re-opening the negative ion generator at a time interval, re-checking a discharge state during re-opening, and if the negative ion generator works normally after being opened for a period of time, judging that the situation is caused by environment type reversible factors and enabling the negative ion generator to restore the normal work. When the operation is repeated multiple times, if the negative ion generator is still in the abnormal discharge state, the abnormal discharge state can be judged to be caused by mechanical fault type non-reversible factors, and an abnormality loop can be timely started to prompt discharge abnormality. According to the detection method disclosed by the invention, timely troubleshooting can be facilitated, and electricity and energy can be further saved.

Description

technical field [0001] The invention belongs to the technical field of negative ion generators, and in particular relates to a method for detecting abnormal discharge of negative ion generators. Background technique [0002] The negative ion generator is a device for generating air negative ions, including a low-voltage DC power supply, a boost circuit, and a negative ion generating module. It raises the low voltage (usually 12V) provided by the low-voltage DC power supply to the DC negative high voltage (usually about -6000V) through the booster circuit, and then uses the tip DC high voltage in the negative ion generating module to generate high corona and release a large amount of ion at high speed. Electrons e-, and electrons cannot exist in the air for a long time (the lifetime of existing electrons is only nS level), and will be captured by oxygen molecules (O2) in the air immediately. It forms negative ions, and its working principle is consistent with the phenomenon ...
