Description

Technical Field

[0001] The utility model relates to the technical field of heating components, in particular to a heating component with a positive and negative ion integrated structure. Background Art

[0002] The current heating component of a high-speed hair dryer does not have positive and negative ions. It consists of: a heating frame plastic, a heating wire, an inner mica sheet, a mica sheet support plate, and an outer mica sheet. When assembling the finished product, an independent positive and negative ion module needs to be assembled with the heating component. The main body of the current positive and negative ion generator component consists of: a positive and negative ion generator housing, a PCBA, epoxy resin, a power cord, a discharge silicone wire, a heat shrinkable tube, a rivet, and a high-voltage discharge needle. The discharge wire is riveted with a rivet and a discharge needle, and the riveting part is wrapped with a heat shrinkable tube. Among them, when one needle is connected to the component main body, it is a negative ion generator, and when two needles are connected to the component main body, it is a positive and negative ion generator. Using this structural component will cause the following complex problems in the production of high-speed hair dryers:

[0003] 1. The PCBA component of the positive and negative ion generator is limited by the space structure. The welding method between many components is the butt welding connection of pins, which needs to be manually completed. This production method is complex, has low efficiency, and is prone to quality problems.

[0004] 2. The silicone wire is butt welded with the component pins, which needs to be manually completed. The efficiency is low, and it is prone to quality problems.

[0005] 3. The silicone wire and the discharge needle are riveted by a rivet, and the riveting part and heat shrinkage are wrapped with a heat shrinkable tube, all of which need to be manually completed. The efficiency is low, and it is prone to quality problems.

[0006] 4. The silicone wire is easy to be damaged, which is likely to cause abnormal high-voltage discharge.

[0007] 5. When assembling the positive and negative ions to the heating frame component, the discharge needle needs to be manually fixed on the outer circle of the heating frame component with a high-temperature resistant tape. The discharge needle is likely to discharge or short-circuit with the heating wire, and the consistency of the position for fixing the discharge needle is poor, resulting in low and inconsistent positive and negative ion concentrations.

[0008] To solve the above problems, a heating component with a positive and negative ion integrated structure is proposed in this application. Summary of the Utility Model
