So that when the discharge control circuit 11 is energized, high voltage discharge is generated between the negative high voltage electrode 12 and the ground electrode 13, and ionized air generates a large amount of negative ions and positive ions in the ionization space. The positive ions and the negative ions can perform positive and negative charge neutralization in the air, huge energy is released instantly during charge neutralization, the bacteria are caused to die due to structural change, and the redundant negative ions can further sterilize and smell-free.

According to the sterilization and odor purification device 10 provided by the scheme, the heating control circuit 14 is used for controlling the heating element 15 to heat the air around the negative high-voltage electrode 12, so that the ambient temperature of the negative high-voltage electrode 12 is increased, and the air corona voltage of the negative high-voltage electrode 12 is reduced. And further, a large amount of ions can be formed by adopting relatively low voltage, so that the sterilization and odor removal effects are ensured. At the same time, the discharge level is reduced due to the lower voltage, thereby reducing the generation of ozone in the process. And the decomposition of ozone can be accelerated to a certain extent when the environmental temperature rises, so that the sterilization and odor removal effects are integrally ensured, and the concentration of the generated ozone is reduced.
Specifically, as shown in fig. 1, in one embodiment, the heating control circuit 14 includes a heating power source electrically connected to the heating element 15, the heating power source is configured to provide an ac voltage of 35v/80kHZ, and the heating temperature of the heating element 15 is 80-85 ℃.

And the negative high voltage electrode 12 is surrounded in the middle and is at a high temperature. With the increase of the temperature of the negative high voltage electrode 12, the energy of the electrons in the negative high voltage electrode 12 is increased, and the required work function is reduced, so that the quantity of the negative ions generated under the same voltage is increased, and the sterilization and odor removal effects are better.
Alternatively, in other embodiments, the heating member 15 may have other shapes. For example, the cylindrical heating member 15 is sleeved outside the negative high voltage electrode 12, and the heating member 15 and the negative high voltage electrode 12 are arranged at intervals.

Further, the heating member 15 may be provided in the conductive cylinder with the heating member 15 being provided in an insulated state from the conductive cylinder. In other words, the heating element 15 is embedded in the wall of the conductive cylinder, and specifically, when the heating element 15 includes the resistance wire, an insulating layer may be disposed outside the resistance wire, so as to ensure an insulating state between the heating element and the conductive cylinder.
Moreover, the heating element 15 is embedded in the wall of the conductive cylinder, so that the overall structure of the sterilizing and deodorizing device is simpler.

Further, in one embodiment, the heating member 15 is a heat-resistant metal heating member. Specifically, the heating member may be made of a heat-resistant metal material such as stainless steel or tungsten.
Further, as shown in fig. 1 and fig. 2, the sterilizing and deodorizing device 10 further includes a first fan 17 for blowing away a large amount of ions generated by the discharge between the negative high voltage electrode 12 and the ground electrode 13 and diffusing the ions into the space to be sterilized and deodorized.
Also, when the ground electrode 13 is the conductive cylinder, the first fan 17 is provided to effectively increase the diffusion speed of ions based on the fact that a large amount of generated ions are accumulated in the conductive cylinder.

Even if the sterilizing and deodorizing device 10 is placed in a low-temperature environment such as a refrigerating chamber 211 or a freezing chamber of the refrigerator 20, the heating member 15 can rapidly heat the ambient temperature around the negative high voltage electrode 12 at the moment when the discharge is required to generate ions, and the heat generated by the heating member 15 does not affect the temperature in the refrigerating chamber 211 or the freezing chamber.
Specifically, the food-grade heat-insulating layer may be PE foam (cross-linked polyethylene foam).
Further, as shown in fig. 3, in another embodiment, a refrigerator 20 is provided, which includes a box 21 and the sterilizing and deodorizing device 10, wherein the box 21 has a refrigerating chamber 211 therein, and the sterilizing and deodorizing device 10 is disposed in the box 21 for feeding ions into the refrigerating chamber 211.
