Campus hair dryers are ultra-high frequency public equipment, and the use of strength and household hair dryers are not at the same level. The normal service life of household personal hair dryers is 5-8 years, while the service life of campus public hair dryers is only 3-8 months. Students concentrate on school and wash at night. The equipment is started and stopped hundreds of times a day, works continuously for a long time, and runs 24 hours a day. Ordinary electric heating wire hair dryer has short life, easy damage and high failure rate, which brings great pressure on maintenance, replacement and operation and maintenance to school logistics.
In order to solve the industry pain point of "intolerable, easy to break and frequent repair" of campus public equipment, the 100-second laughing campus hair dryer developed by dongguan yuzi technology co., ltd. is equipped with PTC ceramic heating element. Compared with the traditional electric heating wire heating, PTC ceramic heating components are more expensive and more complex, but the durability achieves a qualitative breakthrough, which is perfectly suitable for high-intensity use scenarios on campus.
The traditional electric heating wire is a metal heating material, which has fatal defects: after repeated high temperature heating and cooling, the metal wire will continue to oxidize, thin, embrittlement and aging. Under the high-frequency start-up and stop environment on campus, ordinary electric heating wire hair dryers usually experience hot air attenuation, slow temperature rise, burn-out and scrap in just a few months, requiring repeated logistics maintenance and batch replacement, and long-term operation and maintenance costs remain high.
The PTC ceramic non-metallic heating structure used in the special hair dryer for campus developed by Dongguan Yuzi Technology Co., Ltd. has no oxidation, no ablation and no loss in the whole working process. Regardless of the high-frequency switch, day and night use, alternating hot and cold work, the material structure will not age, will not decay. Its theoretical service life can reach tens of thousands of hours, which is several times that of traditional heating wire models.
Because of the ultimate stability and durability, PTC ceramic technology is widely used in new energy vehicle heaters, central air conditioning constant temperature systems and other high durability requirements of equipment.
The most intuitive advantages of landing on campus are: extremely low failure rate, minimal repair, no need for frequent replacement, greatly reducing the workload of school logistics maintenance, greatly reducing the long-term equipment procurement and maintenance costs of schools, and being a cost-effective and long-term choice for public washing and protecting electrical appliances in colleges and secondary schools.
