Abstract

The utility model relates to a heat storage electric warming base plate for writing, which is composed of an oblong bakelite closed shell, a heat storage plate arranged in the oblong bakelite closed shell, a heating wire of which both ends are provided with power connectors, a temperature controller, an insulation material layer, etc. Heat quantity can be slowly released for several hours after energization for several minutes, and the utility model is not required to be energized while in use. The utility model is convenient to carry over, and is especially suitable to be used for warming hands and processing writing work simultaneously in the environment without a power source in winter.

Description

Heat storage writing electric board

The utility model belongs to a kind of electric heating and thermal insulation device, relates to a kind of heat accumulation and writes the electric pad plate, is used for the warm of cold environment human body and hand, pin etc., uses when being particularly suitable for writing work.

In the prior art, in cold season, general hot-water bottle class or the electric blanket class used carried out warm to human body and hand, pin etc., but all exist not enough: the former temperature retention time is short, promptly become the temperature that loses function in the short period of time by higher temperature (being enough to scalded skin), life-span is short, easily leaks, and uses inconvenient.Though the latter can provide substantially invariable temperature, in use must switch on continuously, (for example outdoor, the classroom desk limit of general school etc.) can not use in power free environment, are subjected to condition restriction; Soft surface is write work while can not warm up hand thereon as backing plate; Use more dangerous.

When providing a kind of use, the purpose of the utility model can write the electric pad plate by cold heat accumulation.

Technical solution of the present utility model is that a kind of heat accumulation is write the electric pad plate, comprise that there is the heating wire of power connection at two ends, be connected on the thermostat on the heating wire, it is characterized in that also comprising by upper cartridge body 1 and the lower box body 2 involutory approximate cuboid sealing shells that constitute, be provided with high temperature resistant heat storing plate 5 in this shell, be provided with adiabator layer 6 between high temperature resistant heat storing plate 5 and upper cartridge body 1 and the lower box body 2, spaced one group of groove 8 is arranged on the high temperature resistant heat storing plate 5, heating wire 3 is wrapped in one group of

groove

8, and 2 four jiaos of correspondence positions of upper cartridge body 1 and lower box body have screw hole and screw arranged or bolt 7 is fixedly connected.

Compared with prior art, the utlity model has following characteristics:

(1) adopt insulation and hot non-conductor production upper cartridge body 1 and lower box bodies 2 such as bakelite, plastics, both involutory formations sealing shells, heat scatters and disappears slow, and temperature retention time is long, and surfacing can be write work thereon, safety;

(2) the high temperature resistant heat storing plate 5 be wound with heating wire and adiabator layer 6(are set for example in the sealing shell: heat-preservation cotton etc.), switch on to make slowly release about 3 hours of heat in several minutes, and power saving can no power during use, safety;

(3) the sealing shell can be controlled at proper temperature by thermostat, human body skin can be do not scalded; Volume is less, can carry;

(4) can be used for warm human body and hand thereof, pin, warm quilt etc. are particularly suitable for doing writing backing plate, write work while warm up hand, for example: in winter, last class hour of student, writing warm simultaneously hand.

Fig. 1 is the utility model example structure schematic diagram;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is high temperature resistant heat storing plate 5 structural representations among Fig. 1.

Among the figure: 1-upper cartridge body, 2-lower box body, 3-heating wire, 4-thermostat, the high temperature resistant heat storing plate of 5-, 6-adiabator layer, 7-bolt, 8-groove, 9-terminal screw, 10-circumscripted power line.

Be an embodiment of the present utility model below:

A kind of heat accumulation is write the electric pad plate, by bakelite upper cartridge body 1 and lower box body 2, and heating wire 3, bimetal temperature control device 4, high temperature resistant heat storing plate 5, adiabator layer 6, bolt 7, terminal screw 9 compositions such as grade; The sealing shell of the approximate cuboid of bakelite upper cartridge body 1 and lower box body 2 involutory formations, high temperature resistant heat storing plate 5 places the sealing shell, adiabator layer 6(heat-preservation cotton is arranged) between high temperature resistant heat storing plate 5 and upper cartridge body 1 and the lower box body 2, spaced one group of groove 8 is arranged on the high temperature resistant heat storing plate 5, two ends have the heating wire 3 of power connection to be wrapped in one group of groove 8, make high temperature resistant heat storing plate 5 thermally equivalents; 2 wiring screws and terminal screw 9 are arranged on one inside edge of upper cartridge body 1 or lower box body 2, and two end connectors of heating wire 3 are connected on respectively on the terminal screw 9, and pick out circumscripted power line by these 2 terminal screws 9; Bimetal temperature control device 4(is with commercially available consistent) be connected on the heating wire 3 and be positioned at closure casing, the sampling end of bimetal temperature control device 4 (thermometric end) contacts with the inwall of upper cartridge body 1 with lower box body 2, can cut off the power supply automatically when making housing reach uniform temperature; Four jiaos of correspondence positions of upper cartridge body 1 and lower box body 2 have screw hole and form to seal shell with bolt 7 two box bodys that are fixedly connected.

Claims

A kind of heat accumulation is write the electric pad plate, comprise that there is the heating wire of power connection at two ends, be connected on the thermostat on the heating wire, it is characterized in that also comprising by upper cartridge body 1 and the lower box body 2 involutory approximate cuboid sealing shells that constitute, be provided with high temperature resistant heat storing plate 5 in this shell, be provided with adiabator layer 6 between high temperature resistant heat storing plate 5 and upper cartridge body 1 and the lower box body 2, spaced one group of groove 8 is arranged on the high temperature resistant heat storing plate 5, heating wire 3 is wrapped in one group of groove 8, and four jiaos of correspondence positions of upper cartridge body 1 and lower box body 2 have screw hole and screw arranged or bolt 7 is fixedly connected.
