Embodiment
[0014] Example: see figure 1 , a range hood capable of releasing negative ions, comprising a casing 1, the casing 1 is provided with a negative ion generator 2, and the negative ion generator 2 is equipped with an outward air supply device;
[0015] The negative ion generator 2 can be arranged on the top of the outer surface of the casing;
[0016] Negative ion generator 2 is located at the front of the outer surface of the casing;
[0017] The negative ion generator 2 is controlled by the master switch of the range hood, that is, the negative ion generator and the range hood work at the same time;
[0018] The negative ion generator is controlled independently from the main switch of the range hood, that is, the negative ion generator can work alone and be used as an air freshener;
[0019] Negative ion generator 2 generates negative ions through current discharge, or negative ion generator 2 generates negative ions through photocatalyst;
[0020] Because the anion generat...
