Description

Multi-purpose electronic incense unit

This utility model relates to a kind of electronic heater, particularly a kind of low-power consumption multifunctional electronic fragrance dispenser.

At present, common electronic heater on the market, as electronic mosquito repellent, its internal structure mainly is made up of a pyrotoxin, heat sink and an indicating circuit, heat sink is positioned on the pyrotoxin, pyrotoxin adopts a kind of quasiconductor ferroelectric ceramics that is called ptc material, and it mainly mixes basic constituent element Barium metatitanate. (BaT:O by rare-earth elements of lanthanum (La), samarium (Sm), niobium (Nb), yttrium (Y) ₃) through mold pressing, around tying, being processed by nickel (or silver), cost is higher.According in " the electric world " the 10th phase of nineteen eighty-three " ptc material and application " literary composition to the introduction of ptc material, the curie point of this material is at least more than 150 ℃, that is to say, after energising, when the temperature of material must rise to more than 150 ℃, its resistance could take place to increase suddenly, and electric current reduces rapidly then, material temperature also changes thereupon, to reach temperature automatically controlled effect.But in fact, general scented tea and mosquito-dispelling tablet just can volatilize when 80 ℃ of left and right sides of temperature, so adopt ptc material as heating source, not only power consumption is big, and because temperature is too high, make the abnormal smells from the patient volatilization too fast, incompatible long-term heating to long-acting volatilization scented tea.In addition, the ptc material finished product does not have the wiring pin, is abutted against fully and touches conduction, so inconvenience is installed, also is prone to loose contact.On the structure of existing product, during use, anti-mosquito incense sheet is to insert under two crosspieces from face is flat mostly, so be conditional to the thin and thick of anti-mosquito incense sheet.

The purpose of this utility model is to provide a kind of operating temperature about 80 ℃, and cost is low, dependable performance, the multifunctional electronic fragrance dispenser that the scope of application is wide and the life-span is long.

According to multifunctional electronic fragrance dispenser described in the utility model, mainly form by housing, cap, plug, pyrotoxin, heat sink, spring leaf and an indicating circuit, heat sink and spring leaf lay respectively at the upper and lower of pyrotoxin, it is characterized in that pyrotoxin adopts a high-power cement resistor, the inner shell of housing is provided with the fixed support that is used for fixing heat sink and spring leaf, has adjustable ventilation window on the cap.Pyrotoxin in this utility model, promptly high-power cement resistor, owing to its resistance value is that rising along with operating temperature increases, so, it can very fast realization to the automatic adjusting of operating current, for 8cm ²～12cm ²The heat sink of area, electric current operating temperature when 10mA is following just can be controlled in 60 ℃～80 ℃ scopes, so just can fully satisfy the volatilization temperature requirement of general scented tea and mosquito-dispelling tablet, scented tea and mosquito-dispelling tablet are slowly scented of, to reach the purpose of regulating air or expelling mosquito.In addition, have the ventilation window of adjustable size on the cap in this utility model, so can control by the governor motion on the cap for the indoor climate size.

This utility model compared with prior art, its remarkable advantage is: (1) reduces power consumption.Because pyrotoxin has adopted high-power cement resistor in this utility model, and operating temperature is controlled in 60 ℃～80 ℃ scopes, has both satisfied the volatilization temperature of scented tea and mosquito-dispelling tablet, reduce power consumption 50% than existing product again; (2) cost reduces, and prolong service life.The cost of high-power cement resistor only is 2/3 of existing ptc material, again because this utility model has been controlled operating temperature effectively, is prolonged the service life of long-acting scented tea; (3) scope of application enlarges.Electronic fragrance-spreading device at first described in the utility model, because structural variation, can there be enough big space to lay scented tea or anophelifuge tablet, thus less demanding to their thin and thick, in addition, this electronic fragrance-spreading device can heat the long-acting solid scented tea of various odor types, the room air that is used for spring, summer, four seasons autumn and winter is regulated, and can heat the anophelifuge tablet again, kills mosquito in summer, also can suitably regulate the size of the tolerance of loosing, to satisfy different human needs.The mode of connection of the present utility model both can adopt wall hanging direct insertion, and also available external wire carries and uses all very convenient.

Concrete structure of the present utility model is provided by the following drawings and embodiment.

Fig. 1 is the overall structure profile sketch map of electronic fragrance-spreading device described in the utility model.

Fig. 2 is that the high-power cement resistor of this utility model is at the intravital scheme of installation of shell.

Fig. 3 is the profile of A-A among Fig. 2.
