Abstract

The utility model discloses a far-infrared hand warmer for effectively relieving the bitterness of freezing hands when working at a desk, comprising a conductor, a plug, a switch, a casing, a base, screws and two key members which are a radiation screen 15 arranged in the inner cavity of the casing 10 and an electric heating element whose one end arrange at the vertical direction with the symmetry axis extends into the radiation screen because the dimension is small, the far-infrared hand warmer is suitable to be arranged on a desk; due to the adoption of the radiant type heating, the bitterness of freezing hands can be avoided when working at a desk; because the power is 50W, the energy and the electricity can be saved. The far-infrared hand warmer is suitable for students and workers at a desk.

Description

Far-infrared hand warmer

This utility model relates to a kind of electrothermal heating apparatus, particularly relates to a kind of far infrared hand warmer.

The power that the body local heating installation of current trend has is big, and overall dimensions is big, is unsuitable for being placed on desktop and uses.And mostly be touch heating, for example hot water bag, electricity continuous hot handwarmer CN2073560U, miniature electric heater CN2064476U etc.These heating installations only could warm up and the hands skin when touching, and warm sense is relatively poor, and when working at hand, the thermal source of having to again leave, the hardship of still unavoidable stiff hands.

The purpose of this utility model is to provide a kind of size little, low in energy consumption, need not to touch the far infrared hand warmer that can realize warm hands effect.

The purpose of this utility model is to realize like this, that is: this far infrared hand warmer comprises lead, plug, switch, shell, base and screw, and its key is that the radiation shield in a cased chamber and one and the vertically arranged end of its axis of symmetry stretch into the heating of radiation shield inner chamber.

Described heating is that the electric heating fuse of inner heating type electric iron is transformed and transplanted, heating wire is concentrated around in the scope of top 8～50mm, cold resistance is controlled in 1000～1100 ohm of scopes, when using 220 volts of alternating current power supplys, power consumption is in 45～55W scope, and the hot-zone temperature can reach 600～700 ℃, be become clear orange red, in addition, owing on the ceramic package of heating, be coated with the agent of one deck far infrared radiation, make it to produce far-infrared thermal radiation.In order further to improve the utilization rate of the heat that produces, strengthen warm hands effect, radiation shield is made with bright aluminium sheet or corrosion resistant plate, and the radiation shield bottom design is a curved surface, as arc surface or parabola, thereby makes the concentrated to greatest extent orientation ejaculation of heat.Simultaneously, because heating is away from the desktop article, the radiation shield oral area adds again and blocks bar, can avoid staff and paper to enter radiation shield, has guaranteed the safety of using.For fear of the transconversion into heat of shell, with respect to the unsettled installation of shell, making has enough insulated spaces between radiation shield and the shell with radiation shield, thereby makes the temperature of shell be lower than 60 ℃.

This utility model compared with prior art because its overall dimensions is little, the warm on the table hands of suitable placement; Owing to adopt the radiant type heating, can avoid bending over the desk writing or the hardship of the stiff hands when carrying out other manual labour; Because power is 50W only, so energy saving.Be specially adapted to the usefulness of the warm hands of work when work such as scientific and technical personnel, teacher, student, secretary, administration staff, doctor, writer, typist, computer keyboarder.

Accompanying drawing is a population structure sketch map of the present utility model.

Below with reference to accompanying drawing concrete structure of the present utility model is further described.

Referring to accompanying drawing, this utility model far infrared hand warmer, comprise lead 8, plug, switch 12, shell 10, base 13,

screw

3,6,11,14, its key are that a radiation shield 15 that is installed in shell 10 inner chambers and one and the vertically arranged end of its axis of symmetry stretch into the heating 1 of radiation shield inner chamber.

Switch 12 is housed on base 13, and

screw

3,6,14 is passed through in the chamber within it, spacer 9, and grip slipper briquetting 4 and grip slipper master piece 2 are solidified as a whole one of heating 1 end and base, and by screw 6, bottom 7 the base bottom are sealed.Binding post 5 is embedded in the groove of grip slipper master piece 2.One end of lead links by binding post and heating, and the other end is drawn with plug from the hole of base sidepiece behind tandem tap and linked.Shell 10 by screw 14,11 respectively with radiation shield 15 and base 13 Joints.In addition, be equipped with at the radiation shield oral area and block bar 16.

The shell of present embodiment, base, grip slipper master piece, grip slipper briquetting, bottom are made by plastics.

Claims

1, a kind of far infrared hand warmer comprises lead, plug, switch, shell, base and screw, it is characterized in that a radiation shield 15 that is contained in shell 10 inner chambers and one and the vertically arranged end of its axis of symmetry stretch into the heating 1 of radiation shield inner chamber.

2,, it is characterized in that radiation shield 10 bottom surfaces are a curved surface according to the described far infrared hand warmer of claim 1.

3,, it is characterized in that radiation shield 10 oral areas block bar 16 according to claim 1,2 described far infrared hand warmers.

4,, it is characterized in that being coated with the far infrared radiation agent on the ceramic package of heating according to the described far infrared hand warmer of claim 1.
