If there is a large temperature difference, the heating rate of the heater plate 1406 is quickly adjusted. In this embodiment, the heating plate 1406 and the temperature sensor 17 are connected to an external control circuit, so that the heating rate of the heating plate 1406 is adjusted or the set temperature of the skin care product is adjusted by the signal collected by the temperature sensor 17. In other embodiments, both the heater chip 1406 and the temperature sensor 17 are connected to an internal control unit 15.

In other embodiments, the heating device 14 may also be an infrared heating device, specifically a heating device using infrared light tubes.

In this embodiment, the first heating chamber and the second heating chamber are both circuitous coil channels. In other embodiments, the first heating chamber or the second heating chamber is a serpentine coil channel. In yet other embodiments, the first heating cavity and/or the second heating cavity are straight tube channels. Specifically, the straight pipe channel is easy to produce, the space utilization rate of the coil pipe channel is high, and the heat transfer area per unit volume is large.

In this embodiment, the housing 1 is provided with a first indicator lamp 7 and a second indicator lamp 8, the base plate 2 is provided with a control unit 15, and the first indicator lamp 7 and the second indicator lamp 8 are electrically connected with the control unit 15 respectively. Specifically, the first indicator lamp 7 may indicate the heating state by being displayed in a different color, indicating that heating is being performed or that heating is completed, or the like. The second indicator lamp 8 may indicate whether the power is on, whether the power is sufficient, etc. by means of the brightness, the blinking, etc. The shell 1 is also provided with a switch button 6 electrically connected with the electrical appliance unit, the control unit 15 is also provided with a power interface 16, and the shell is provided with a power connection hole 9. In this embodiment, the power connection hole 9 and the ventilation hole are the same hole. In other embodiments, the power connection hole 9 and the ventilation hole are two different holes, respectively.

Example two

The difference between this embodiment and the first embodiment is that:

one end of the connecting tube 18 near the thread groove penetrates the bottom of the thread groove and extends to the bottom of the packaging bottle 10.

In the first embodiment, the skin care product heater is placed upright, and the packaging bottle 10 of skin care product is placed upside down above the first connecting portion 3 in order to utilize the hydraulic pressure of skin care product.

In this embodiment, the packaging bottle 10 is placed vertically, the skin care product heater is placed upside down above the packaging bottle 10, and the gravity of the skin care product is overcome by the suction force of the injection pump 4, so that the skin care product in the packaging bottle 10 is sucked into the three-way valve 12 through the connecting pipe 18.

The terms "first," "second," "third," and "fourth" are used herein for descriptive purposes only and are not intended to be limiting.

It should be noted that the specific features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, the present invention will not be described in any detail with respect to the possible combinations.

Moreover, any combination of the various embodiments of the invention can be made without departing from the spirit of the invention, which should also be considered as disclosed herein.
