Description

Electronics cold, hot two-purpose callosity

Technical field

This utility model relates to electronic health apparatus, particularly relates to a kind of electronics cold, hot two-purpose callosity.

Background technology

Fig. 1 is the semiconductor refrigerating principle, can be divided into 2 parts and study.When the polarity of electric current as shown in the figure the time, electronics is from power cathode, through sheet metal node 4, and P-type semiconductor, node 1, sheet metal is got back to positive source.But because of the left side is a P-type semiconductor, electrically conducting manner is a cavity type, and the hole flow direction is opposite with the electronics flow direction, so the hole is from sheet metal, and node 3, P-type semiconductor, node 4, sheet metal is got back to power cathode.The energy that the hole is had in the middle of metal, the energy that is lower than in quasiconductor to be had.When the hole under electric field action, by node 3, when arriving P-type semiconductor, must increase part energy by sheet metal.But hole itself can't oneself increase energy, has only to absorb energy from sheet metal, and this part heat energy is become the potential energy in hole, thereby just reduces in the temperature of the sheet metal at node 3 places.And lead to node 4 when flowing to sheet metal along P-type semiconductor when the hole, because the energy in hole is greater than the energy in hole in the metal in the P-type semiconductor, thereby to discharge unnecessary potential energy, and change it into heat energy and discharge, so that the temperature of node 4 place's sheet metals raise.And right-hand part is linked by n type semiconductor alloy sheet among Fig. 1, by the free electron conduction.The potential energy of electronics in metal is lower than the potential energy in n type quasiconductor, under effect of electric field, electronics is recognized when sheet metal arrives n type conductor by node 2 must increase potential energy, this part potential energy also can only be obtained from the heat energy of sheet metal, thereby the temperature of node 2 place's sheet metals is reduced, when electronics from n type quasiconductor through node 1 when flowing to sheet metal, because of electronics is to flow to the lower place of potential energy by the higher place of potential energy, so discharge unnecessary potential energy, and be transformed into heat energy, the temperature of node 1 place's sheet metal is raise.From above-mentioned analysis as can be known, the temperature of upper metal sheet reduces, and becomes cold junction, and the sheet metal that temperature is low just makes surrounding medium obtain cooling from the surrounding medium heat absorption like this, thereby has reached refrigerating purpose; Bottom two connects then heat release of sheet metal, becomes the hot junction, and the heat that the hot junction is produced when refrigeration must be drained.

Otherwise, when needs heat,, get final product as long as with error-polarity connection of power supply.

The health of foot and human body has very big relation, we can say that foot is the root in people's the root.Above-mentioned technology can play a role aspect body-care, but not be applied on foot health promotion as yet.

The utility model content

The purpose of this utility model provides a kind of callosity, can improve foot's blood circulation, thereby strengthens the whole immunologic function of human body.

For achieving the above object, technical solution of the present utility model provides a kind of electronics cold, hot two-purpose callosity, contains callosity, semiconductor cooling device and power supply, and there are semiconductor cooling device and power supply in its callosity below; Refrigeration device comprises A end, B end, plate, switch; A, B two ends are electrically connected by P-type semiconductor, N-type semiconductor respectively; The A end is connected in a plate lower surface, and plate upper surface and callosity the inside join; The B end is electrically connected with switch, power supply respectively; It is the protective cover parcel that B holds a side, and the protective cover upper end links to each other with the callosity right-hand member, and lower end and callosity bottom fuse; Switch is arranged on the refrigeration device, and switch links to each other with power supply.

Described electronics cold, hot two-purpose callosity, its described refrigeration device also comprises fin, and it is located between A, the B two ends, and fin and A end are insulated from each other, and its flat side links to each other with a side of B end.

Described electronics cold, hot two-purpose callosity, its described plate, fin are the aluminum or aluminum alloy goods.

Described electronics cold, hot two-purpose callosity, its described switch is made as three retainings, and one closes retaining, a heating retaining, a refrigeration retaining.

This utility model electronics cold, hot two-purpose callosity utilizes semiconductor refrigerating/thermal device as refrigeration/thermal source, and foot is in the predetermined ambient temperature range all the time, promotes foot's blood circulation, strengthens people's autoimmunity.Because electronics cold, hot two-purpose callosity do not have the machine operation part, thereby noiseless, friction when using, comfortable during use.This pad is novel in design, simple in structure, long service life, functional reliability height, be suitable for industrialized mass.
