Huangmao Electronic Deworming Machine (removal of Four Pests) series products can simultaneously generate extremely low-frequency electromagnetic wave induction fields, dual ultrasonic waves and bionic waves. The same products in the world are only ultrasonic waves, plus electromagnetic waves, and the three types of electric waves generated by the product. The frequency of the disease is constantly changing intermittently, so that pests such as mice will not "adaptability" and "immunity" to a certain fixed frequency. The ultra-low frequency electric field conversion technology of the product is novel or professional. : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : :
