Embodiment 1

[0020] Such as figure 1 , figure 2 As shown, a foot bath heating device with low inductive electricity includes a heating element 1, and the outer side of the heating element 1 is also provided with a metal shielding layer 2 that maintains electrical connection with it and can reduce inductive electricity. The metal shielding layer 2 A basic insulating layer 3 is provided between the heating element 1 and on the outside of the metal shielding layer 2 .

[0021] The input end of the heating element 1 is connected to the metal shielding layer 2 through a conductive connecting piece 6 . In order to ensure the insulation performance of the heating device, the outer side of the basic insulating layer 3 arranged on the outer side of the metal shielding layer 2 is also covered with an additional insulating layer 4 . The basic insulating layer 3 and the additional insulating layer 4 are insulating materials with good thermal conductivity.

[0022] In this embodiment, the heating e...

Embodiment 2

[0024] Such as image 3 , Figure 4 , Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the heating element 1 adopts PTC ceramic sheet, the metal shielding layer 2 is aluminum foil, copper foil or tin foil; the basic insulating layer 3 and the additional insulating layer 4 are polyamide The imine film is superimposed and formed.

Abstract

The invention discloses a low-faradism footbath machine heating device which comprises a heating element (1), wherein a metal shielding layer (2) kept in electrical connection with the heating element and capable of reducing faradism is arranged on the outer side of the heating element (1). A basic insulating layer (3) is arranged between the metal shielding layer (2) and the heating element (1), and a basic insulating layer (3) is arranged on the outer side of the metal shielding layer (2). According to the invention, by arranging the metal shielding layer outside the heating element of a footbath machine, the faradism of the heating device in work can be remarkably reduced; and meanwhile, two heat-conduction insulating layers are encapsulated on the surface of the shielding layer so that the heating device has double-insulation performance, and the product is safe and reliable on the premise of guaranteeing the heating efficiency.

Description

technical field [0001] The invention relates to a heating device for a foot bath with low induction electricity, which belongs to the improvement technology of the heating device for a foot bath. Background technique [0002] The commercially available foot bath belongs to the second-class electrical appliance in the safety standard of household appliances, which adopts double insulation or supplementary insulation, and there is no grounding requirement. However, due to the particularity of the use environment of the foot bath, when the foot bath is working, the induced electricity generated by the distributed capacitance formed by the heating device and water cannot be eliminated by grounding, resulting in the induced electricity acting on the human body during the use of the foot bath, making people Produce numbness, serious even produce tingling pain, bring bigger health and safety hidden danger. Contents of the invention [0003] The object of the present invention is...
