[0002] Leakage protectors have been widely used in various fields, and have played a great role in the safety of personal equipment. However, some electrical equipment, especially electronic health care massage footbaths, still have leakage protection that may not work or not work at all. Hidden dangers of health care massage and foot washing have spread all over the country in all cities and towns. Every day, millions or even tens of millions of people soak their feet and massage, which has great potential safety hazards.
The reason is that the electronic health care massage footbath is not equipped with a leakage protector or the leakage protector is not installed. The reason is that the existing leakage protectors are all protective against earth leakage. At present, because most of the electronic health care massage foot bath basins are plastic shells that are not connected to the water pipes and are insulated from the earth, the water in the basin will generate a potential gradient. If the human body's feet are placed in the basin, the human body and the earth are also insulated. The potential difference of the water under the feet will cause people to get an electric shock

Embodiment Construction
[0008] specific implementation plan
[0009] The non-ground leakage protection device of the electronic health care massage foot bath basin of the present invention is to install a metal or conductive rubber A with good conductivity and a metal or conductive rubber B, metal A or Conductive rubber A is connected with metal or conductive rubber B after passing through the hole of the zero-sequence current transformer (5) in the leakage protector (2) with a wire. When the heating tube ruptures or other reasons cause electric leakage, if there is a potential difference between the two points of metal A and metal B, the primary current passing through the hole of the zero-sequence current transformer (5) in the leakage protector (2) will be out of balance, and the zero-sequence The output signal of the secondary coil of the current transformer (5) passes through the amplifying circuit (4) to make the trip switch (3) act, and the power supply of the electronic healthcare massage foo...

The invention relates to a leakage protector, in particular a reliable absence-of-ground leakage protector of an electronic health-care massage foot basin. The traditional leakage protector of the electronic health-care massage foot basin has the inoperative hidden trouble. The absence-of-ground leakage protector is characterized in that favorably conductive metal A and B are installed on each side at the bottom of the electronic health-care massage foot basin; the metal A connecting line perforates the zero sequence current mutual inductor in the leakage protector and is then connected with the metal B; when leakage occurs, primary current of the current mutual inductor loses balance, the secondary current signal is amplified to enable a trip switch to operate, and the electronic health-care massage foot basin is in outage, thereby the purpose of leakage protection is achieved.
