[0002] Facial cleansing instruments are a new type of facial cleansing tool in recent years. Generally, facial cleansing instruments need to be used with facial cleansing lotion to achieve a better effect of removing facial oil and cuticles. When the facial cleansing instrument vibrates, it can help the facial cleansing lotion form high-density uniform foam, and can also massage the face and achieve the effect of beauty and health care.

[0003] Most existing facial cleansing devices use electric pumps to extract the cleansing lotion stored in the facial cleansing device and pump the cleansing lotion onto the brush head of the facial cleansing device. This method of pumping with an electric pump makes it difficult to control the "extrusion amount" of the cleansing lotion. There is a certain hysteresis effect when the pump is stopped, which will cause waste of lotion. In addition, the cost and failure rate of using an electric pump are high. In addition, most existing facial cleansing devices use ultrasonic devices to vibrate the fine hairs on the facial cleansing device to massage the face, and the production cost of such facial cleansing devices is relatively high.
