Abstract
The utility model relates to a warming device which comprises an electric heating body part, a heat-insulating layer 3 and a casing. The utility model is characterized in that the electric heating body part is provided with a PTC element 1 and two supply leads 2 which pass through the casing and the heat-insulating layer to be respectively connected with both electrodes of the PTC element. The product of the utility model has the characteristics of fast heat generation, automatic and constant temperature, no open flame, convenient operation, safety, long service life, etc.
Description
The utility model relates to a kind of warmer.
Existing a kind of heating wire that adopts is the warmer of heater element, and its major defect is: will make temperature too high or cause scaling loss when 1, conduction time is long; 2, heating wire is fragile, and product is short service life.
The purpose of this utility model is to provide a kind of heating fast, automatic constant-temperature, and the warmer of the flames of anger, it is not only easy to use, safety, and also the life-span is long.
Warmer of the present utility model comprises the electric heating element part, is positioned at electric heating element part peripheral heat-insulation layer and shell, it is characterized in that: electric heating element partly has the PTC element and passes the power supply lead wire that shell and heat-insulation layer are connected with PTC element the two poles of the earth respectively with two.
The PTC element that the utility model adopts is a kind of high-tech product that develops rapidly in the world in recent years, the ownership sensitive ceramic, and its bulk resistor is to responsive to temperature.Because its room temperature resistance is less, thus power up the bigger initial current of Shi Youyi (0.3～3A), PTC is generated heat rapidly, in very short time (decide on heat load to a few minutes several seconds zero point), meet and exceed curie point; At this moment, because the rapid rising of PTC body resistivity, make the electric current that the flows through PTC several magnitude that descends rapidly.After treating thermal balance, its electric current just is stabilized in a certain than (claiming aftercurrent, about 30～100MA) on the fractional value.At this moment, the temperature in the heat load is just invariable, the corresponding minimizing of power consumption.Therefore, utilize this function, just can make that a kind of heating is fast to it, automatic constant-temperature, power saving, safety (flames of anger), novel heating element that the thermal efficiency is high, and its life-span is extremely long.In addition, it also has a unrivaled advantage of other heater, is exactly the biddability to supply voltage, and it is subjected to the influence of mains fluctuations minimum.Heater with it is made both can be used for 220V, also can be used for 110V, and need not change-over switch.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the utility model embodiment organigram.
Fig. 2 is an attaching plug section construction schematic diagram, and Fig. 3 is the A-A cutaway view of Fig. 2, and Fig. 4 is the B-B cutaway view of Fig. 2.
With reference to accompanying drawing, this reality novel the PTC element 1 that comprises, power supply lead wire 2, heat-insulation layer 3 and housing 4.It is aluminium block that the two poles of the earth of PTC element are respectively equipped with the conduction, the conduction of thermal store 5(present embodiment, the thermal store that are connected with the inner of power supply lead wire).The outer end of power supply lead wire is connected with the tubular pedestal 8 that is built-in with stage clip 6 and steel ball 7 that is fixedly arranged on the housing, top one pin 9 of tubular pedestal is hinged with the plug blades 10 that is plugged in its epicoele, and the lower end of plug blades is provided with and steel ball 7 contacted positioning recess 11.The side on tubular pedestal top is provided with so that plug blades is folded to the opening 12 of surface of shell.
During use, the user can dial plug blades earlier, plug blades just is in vertical state under the effect of the elastic force of stage clip 6 and the steel ball 7 that places positioning recess 11, again plug blades is inserted supply socket, sheet can pull the plug out of the socket after heat time heating time (getting final product in general about ten minutes), and make it to be equivalent on the housing wall, so that heating is carried, is received and kept.Embodiment of the present utility model is owing to be provided with the aluminium block thermal store, so temperature retention time is longer.
Than existing warmer, the utlity model has following remarkable advantage: 1, heating is fast, and structure is compact, and is easy to use, and 2, automatic constant-temperature, do not scald human body because of excess Temperature; 3, the flames of anger, conduction time longer can scaling loss yet, safe and reliable. 4, the life-span is long. Therefore, be a kind of Domestic electrical equipment that rather is suitable for.
