Abstract

The utility model relates to the magnetic material technical field, which is designed for using on medical treatment, healthcare and food industry, the inside is provided with a magnet body, the utility model is characterized in that the surface of the magnet body is wrapped with a PTEE plastic layer which wraps the magnet body through the paint spraying, embedding or sleeve structures, which is also characterized in non-toxic performance, high temperature resistance and corrosion resistance, and can be directly contacted with human or food, and is suitable to be popularized in medical and healthcare, etc.

Description

Magnetic

Technical field

The utility model relates to a kind of magnetic material technology field.

Background technology

Along with social progress and constantly development of science and technology, people recognize that magnetic material has certain therapeutic action to human body, so adopted magnetic widely in a lot of occasions, as the health therapy utensil, the massage chair, massage apparatus, cup for magnetizing water etc. have all adopted magnetic patch, but its surface of magnetic in the past is to electroplate to go up a kind of metal protective film such as nickel, zinc, copper or tin material, there is certain limitation in it, the one, very high to the electroplating quality requirement, for the health care device, in use also come off easily, cause and get rusty, even cause health care device and send out rust and rot, shorten its useful life; The metallic nickel that plates on the other hand, zinc, copper or tin material do certain harm to human body, can not directly contact human body, so have deadly defect aspect medical, health care, limit it and are extensive use of; At food beverage industry,, also limit it and promote the use of because it cannot contact with food at all; Therefore improving aspect the coated of magnetic surface, promote its range of application and need do further development.

Summary of the invention

Technical problem to be solved in the utility model be provide a kind of at prior art and can directly contact human body or food, at magnetic medical, that healthcare field has practical function.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this kind magnetic, its inside is a magnetic patch, it is characterized in that described magnetic patch is coated with the polytetrafluoroethylplastic plastic layer.

Above-mentioned polytetrafluoroethylplastic plastic layer is to be sprayed on the magnetic patch surface to form totally-enclosed protection thin layer, and its THICKNESS CONTROL is at 0.05-0.3mm.

Above-mentioned polytetrafluoroethylplastic plastic layer forms the magnetic patch potting in its inside totally-enclosed protective layer, its THICKNESS CONTROL is more than 0.25mm.

Above-mentioned polytetrafluoroethylplastic plastic layer is to form totally-enclosed containment vessel by vinyl cover and plastic bottom shrink-fit structure.

Compared with prior art; advantage of the present utility model is: nontoxic being coated with of magnetic; high temperature resistant; corrosion resistant polytetrafluoroethylplastic plastic layer; polytetrafluoroethylplastic plastic is named the Teflon again; E-4 etc.; it makes magnetic reach the hygiene and health requirement; can directly contact human body or food and medical; and it is nontoxic; high temperature resistant, can prevent the magnetic rust corrosion, medical; the health care aspect can be promoted the use of; and structural manufacturing process is ripe practical; protective layer can be made very thin, reduces magnetic resistance as far as possible, improves the magnetization effect; cost is low, has very big practical value.

Embodiment

Below in conjunction with description of drawings embodiment of the present utility model is described in further detail.

Embodiment 1

As Fig. 1, be sprayed on the magnetic surface with polytetrafluoroethylene liquid material by spraying coating process, form through overbaking again, form thickness on magnetic patch 1 surface like this and do the protective film layer at 0.05-0.3mm scope, totally enclosed polytetrafluoroethylplastic plastic layer 2.

Embodiment 2

With the polytetrafluorethylepowder powder material magnetic potting being suppressed the back high temperature sintering in powder forms, it with magnetic magnetic patch 1 potting on 2 li on totally-enclosed polytetrafluoroethylplastic plastic layer, its thickness generally is controlled at more than the 0.25mm, decides according to client's needs as for its final thickness.

Embodiment 3

As Fig. 2; form at the bottom of polytetrafluoroethylplastic plastic lid 3 and the polytetrafluoroethylplastic plastic 4 with the polytetrafluoroethylplastic plastic particle by Shooting Technique, vinyl cover cooperates with plastic bottom, has shrink-fit structure; this shrink-fit structure is a lot; can be varied, have annular groove, another open loop shape inserted sheet as one; also can an open loop row location hole; another open loop row pin or the like, they are fixed on the inside with magnetic magnetic patch 1, and cover forms totally-enclosed polytetrafluoroethylene containment vessel altogether then.

Embodiment 4

Can directly be injected at polytetrafluoroethylplastic plastic and form totally enclosed shell on the magnetic patch, its thickness generally is controlled at more than the 0.25mm, decides according to client's needs as for its final thickness.
