Embodiment Construction

[0014] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] see figure 1 The booster circuit of the portable beauty instrument provided by the embodiment of the present invention is connected with the transducer sheet 13 of the portable beauty apparatus and the battery BAT, and is used to increase the voltage output by the battery BAT to drive the transducer sheet 13 to vibrate. 13 vibrations atomize the water or essential oil stored in the body of the portable beauty instrument into micron-level ultrafine particles, and release negative ions to keep the facial skin moisturized and achieve the beauty effect.

Abstract

The invention discloses a booster circuit of a portable beautifying instrument. The booster circuit is connected with a battery and a transduction sheet of the portable beautifying instrument. The booster circuit comprises a booster chip, a voltage stabilizing tube, a first inductor, a first resistor, a second resistor, a third resistor, a first capacitor, a second capacitor, and a switching module for changing division ratio of the resistors connected in parallel so as to enable the booster chip to output different voltage. According to the booster circuit, the division ratio of the feedback resistors is changed by the switching module, so that the feedback voltage ratio of the of the booster chip can be adjusted, the amplitude of the transduction sheet can be changed, and as a result, the spray quantity can be adjusted; meanwhile, the booster circuit has the characteristics of being simple in structure and low in cost.

Description

technical field [0001] The invention relates to a beauty instrument, in particular to a booster circuit of a portable beauty instrument. Background technique [0002] At present, the boost circuit has been widely used in electronic products. It is mainly used to increase the voltage of the battery in the electronic product to the voltage required for the operation of the electronic product. , and its increased voltage value is also fixed, which cannot meet the needs of electronic products for working voltage conversion. [0003] Thereby prior art still needs to improve and improve. Contents of the invention [0004] In view of the shortcomings of the prior art above, the object of the present invention is to provide a boost circuit for a portable beauty instrument, which can adjust the driving voltage of the transducer sheet through a switching module. [0005] In order to achieve the above object, the present invention has taken the following technical solutions: [00...
