Accompanying drawing to be herein merged in specification and to form the part of this specification, shows the embodiment meeting the application, and is used from specification one principle explaining the application.
Embodiment
Also by reference to the accompanying drawings the application is described in further detail below by specific embodiment.
As shown in Fig. 1 to 7, the embodiment of the present application provides a kind of heat generating component 1, and this heat generating component 1 heats use for electric foot warmer 2.Comprise the cement heating board 12 and heating resistance wire 10 be made up of mortar.Cement heating board 12 comprises winding district 120 and assembly section 122, two 122, two, assembly sections and is symmetricly set on the two ends being wound around district 120, each assembly section 122 is provided with installation gap 122a and heating resistance wire fixed gap 122b.Bottom electric foot warmer 2, be provided with two fixing points 20 for fixing cement heating board 12, each assembly section 122 is seated on a fixing point 20 respectively, and is fixed by the screw mandrel be fixed in installation gap 122a.
Heating resistance wire 10 is wrapped in and is wound around periphery, district 120, and is covered with surface, winding district.The quantity of heat production of heating resistance wire 10 can be made like this to diffuse to whole cement heating board, and be no longer confined in very little scope, because this increasing heating area.The two ends of heating resistance wire 10 are fixed in a heating resistance wire fixed gap 122b respectively by screw mandrel and nut, and whole heating resistance wire 10 can be wrapped on cement heating board 12.
In the present embodiment, by extending the length of resistance wire, make the heating temp of heating resistance wire 10 lower than 300 DEG C.This temperature is lower than the heat resisting temperature 300 DEG C ~ 500 DEG C of mortar, thus the present embodiment cement heating board 12 that mortar material can be adopted to make, thus the cost reducing electric foot warmer heating carrier, and the trouble making or add, meanwhile, product quality is also improved.
About the shape of cement heating board, be wound around district 120 with the part between two assembly sections 122 for bloster portion 120c, the sidepiece of bloster portion 120c stretches out and forms wound portion 120d.The cement heating board 12 of single electric foot warmer, its part between two assembly sections belongs to the bloster portion 120c needing most load-bearing, and the both sides of bloster portion 120c all stretch out and form wound portion 120d, make whole cement heating board 12 form similar certain herbaceous plants with big flowers flower-like structure (see Fig. 3), therefore need the thickest.Be positioned at the wound portion 120d unsettled thirty years of age of 120c both sides, bloster portion, need bloster portion 120c to be provoked, thus under the prerequisite not affecting structure and making, deadweight should be reduced therefore the thinnest (see Fig. 4) as far as possible as far as possible.This design can also strengthen heating resistance wire 10 is arranged on top step yoke spacing with it indirectly, adds the coefficient of safety of electric foot warmer.The bloster portion 120c of the cement heating board 12 of many people electric foot warmer only extends to form wound portion 120d to side, and hanging part is in corresponding opposite side (see Fig. 5 and 6).
Heating resistance wire 10 can adopt the materials such as ferrum-chromium-aluminum, nickel chromium iron or nichrome, and the diameter of heating resistance wire 10 is generally 0.1-0.35mm, and length is 6-10m, can ensure to access the heating temp of local on resistance wire after family expenses 220V power supply below 200 DEG C.The optimal material of heating resistance wire is ferrum-chromium-aluminum, and optimum diameter is 0.25mm, and optimum length is 8m.
Due to heating resistance wire 10 directly exposed being wrapped in be wound around in district 120, therefore in order to prevent heating resistance wire 10 too intensive and localized contact occurs in winding process, resistance is caused to reduce, the negative consequences such as heating temp rising, the both sides that the present embodiment is being wound around district 120 are distributed with row's separation trough 120a, spacing between adjacent two separation trough 120a is equal, for 7-11mm, be preferably 9mm, afterwards the separation trough 120a of heating resistance wire 10 along both sides is wound around, makes heating resistance wire 10 by separation trough 120a institute partitioned arrangement.Owing to leaving separation pitch between separation trough 120a, therefore effectively can prevent heating resistance wire 10 from local occurring and touch short circuit problem.
As shown in Fig. 3, Fig. 5, due to the present embodiment employing is that the mode be wound around arranges heating resistance wire 10, therefore can to surrounding homogeneous radiation heat, and the side in order to make cement heating board 12 heat carried on the back towards side, heating face also can arrive heating face, and preventing local temperature on cement heating board too high, the present embodiment is also provided with louvre 120b in winding district 120.Heat is made to pass through cement heating board 12 louvre and directly rise in insulation quilt.
Confirm through experiment, in use, on cement heating board 12, maximum temperature is only below 100 DEG C for the heat generating component 1 in the present embodiment, is 10 years its useful life.
In the present embodiment, cement heating board 12 is make of cement, fine sand and clear water.Common composite Portland cement can be adopted to coordinate common thin rock sand, and this kind of cement heating board 12 cost is low, uses when can be used as the electric foot warmer made without the need to withstand high temperatures.
Cement heating board 12 in the present embodiment is made by the following step:
A, cement, fine sand and clear water three mixed furnishing and to wet pulverulent material, the one-tenth that wet-milling shape is with hand is pinched sticks together, not faling apart of pine;
B, wet pulverulent material inserted compacting in mould and form cement heating board;
C, by cement heating board, wet water health 15-20 days is shaping continuously in good time.
Its proportioning, in units of weight, makes the ratio of wet-milling with cement, fine sand, clear water is: 1 to 0.7 ~ 1.5 to 0.2 ~ 0.4, and cement and fine sand are good with the mixing ratio of 1 to 1.
The foregoing is only the preferred embodiment of the application, can not be interpreted as the restriction to the application, for a person skilled in the art, the application can have various modifications and variations.Within all spirit in the application and principle, any amendment done, equivalent replacement, improvement etc., within the protection range that all should be included in the application.
