Description

Adjustable heater

Technical Field

The invention relates to daily necessities, in particular to a heater.

Background

Perfume heating and fragrance dispersing usually works in a water heating fragrance mode, namely, a few drops of perfume are added into water, and then the perfume is heated and dispersed. The perfume dispersing mode by water heating has the defects of long heating time, low heating efficiency, short perfume dispersing time, repeated addition of perfume, and incapability of controlling the perfume dispersing speed when the perfume is heated by water, and most of perfume is insoluble to water. The heating fragrance-dispersing device heats the perfume in an electric heating mode, so that the perfume generates fragrance continuously and slowly after being heated. At present, the following problems exist in the use process of the heater: 1. the flash point of perfume is lower, and the volatilization velocity is very fast, and foreign heater often controls perfume volatilization velocity through the partial sheltering of fragrance diffusing hole, does not have any actual effect. 2. If the existing heater can control the volatilization speed of perfume, the product is large in volume or complex in structure. Or most heaters on the market are small in size but lack a device for controlling the perfume volatilization speed, such as CN203971786U patent application, published by lao liao 2014, 7 and 17, "alternating current aromatherapy machine", which has no device capable of adjusting the perfume volatilization speed. Meanwhile, the plug can not rotate, and the use is inconvenient due to space limitation in use. 3. The existing heater generally has no function of intuitively feeding back the perfume allowance. Of course the heater described above can be used to heat other liquids as well. For example, CN205579280U, "a fragrance heater small night lamp" includes a lamp holder body, which includes a lamp holder outer shell and a lamp holder inner shell, and is provided with LED lamp beads, and realizes an illumination function and a fragrance function at the same time.

In view of the above technical problems, there is a need for an adjustable heater with a simple structure, which can effectively control the volatilization speed of liquid and has a function of indicating the remaining amount of liquid.
