Abstract
The utility model discloses a heating core of a shoe dryer, comprising an outer porcelain duct (1), an inner porcelain duct (2), an outer lead (3), an inner lead (4) and a resistance wire (5), wherein the inner porcelain duct (2) extends into the outer porcelain duct (1); the inner lead (4) is a low-melting point alloy wire, and the melting point is 180-350 DEG C; one end of the inner lead (4) passes through the inner porcelain duct (2), twists and is connected with one end of the resistance wire (5); the resistance wire (5) is wound and covered on the inner porcelain duct (2); and the other end of the resistance wire (5) is connected with the outer lead (3). The utility model has the advantages of smart conception, simple structure and easy processing and manufacturing; in addition, the potential safety hazard is effectively eliminated while the safety and reliability of the shoe dryer are improved.
Description
Technical field
The utility model relates to a kind of shoe drier, particularly the heat generating core of shoe drier.
Background technology
Shoe drier plays the oven dry shoes, can remove moisture in the footwear, eliminates bacterial growth.Known shoe drier has two heaters that linked together by the tandem circuit, and this heater adopts conventional inner heating type electric iron core, and power is 20W.The lead of Electric soldering iron core adopts nickel filament, and fusing point is at 1455 degree.When heater is in the work of 1/4 power rating, power is lower, if any docking point of series circuit contacts, one of them heater will not have electricity and will not generate heat, and another heater will recover former power, reach 4 times of heatings of existing power, can the shoes that be toasted are roasting bad, even the meeting initiation fire, there is serious potential safety hazard.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of safe and reliable shoe drier heat generating core.
The technical solution of the utility model is as follows: a kind of shoe drier heat generating core, comprise outer porcelain duct, interior porcelain duct, outer lead, lead and resistance wire, wherein interior porcelain duct stretches in the outer porcelain duct, its key is: described lead is the low-melting alloy silk, fusing point is 180～350 ℃, and an end of described lead passes from interior porcelain duct, and circuitous back links to each other with an end of resistance wire, on the porcelain duct, the other end of resistance wire is connected with outer lead this resistance wire in being enclosed within.
Adopt above technical scheme, when the series circuit of shoe drier did not have short circuit, two heaters all were in 1/4 power rating, and temperature is extremely low, and the lead of heater adopts the low-melting alloy silk, can bear this temperature, made circuit keep normal; When any docking point of series circuit contacts, one of them heater will not have electricity and will not generate heat, and another heater enters the heating of 4 times powers, this moment, the lead of this heater can't bear this higher temperature, can fuse, so entire circuit disconnects, and can not cause the damage to baked article.
As preferably, described lead is the lead-antimony alloy silk, and fusing point is about 327 ℃; Perhaps, lead adopts the leypewter silk, and fusing point is 183～250 ℃.
Beneficial effect: the utility model is skillfully constructed, simple in structure, processing and fabricating is easy, when improving shoe drier security and reliability, has effectively eliminated potential safety hazard.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the circuit diagram of shoe drier.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model is made of outer porcelain duct 1, interior porcelain duct 2, outer lead 3, lead 4 and resistance wire 5, the inner of wherein interior porcelain duct 2 is stretched in the outer porcelain duct 1, the outer end of interior porcelain duct 2 exceeds the end face of outer porcelain duct 1 respective end, and its length direction of body upper edge of porcelain duct 1 is around being with resistance wire 5 outside interior porcelain duct 2 is positioned at.Described lead 4 is the low-melting alloy silk, and fusing point is 180～350 ℃.Lead 4 is preferably lead-antimony alloy silk or leypewter silk, also can be fuse or solder stick that other type fusing point is close.The inner of described lead 4 is passed from interior porcelain duct 2, and circuitous back links to each other with an end of resistance wire 5, and the other end of this resistance wire 5 is connected with the inner of outer lead 3.Draw from the outer end of interior porcelain duct 2 outer end of lead 4, and the outer end of the outer end of outer lead 3 and lead 4 is drawn outer porcelain duct 1 in the same way.
From Fig. 2 and in conjunction with shown in Figure 1, shoe drier has two heaters 6,7, aforesaid heat generating core is housed in each heater, the heat generating core of two heaters 6,7 is cascaded by lead, and a, b, c, d, e, f, g are the contact that connects lead, when the series circuit of shoe drier does not have short circuit, two heaters 6,7 all are in 1/4 power rating, temperature is extremely low, and the lead of each heater can bear this temperature, makes circuit keep normal; When any docking point of ac, bc, de, the fg of series circuit contacts, one of them heater will not have electricity and will not generate heat, and another heater enters the heating of 4 times powers, this moment, the lead of this heater can't bear this higher temperature, can fuse, so entire circuit disconnects, and can not cause the damage to baked article.
Claims (3)
