Description

Technical Field

[0001] The present invention relates to the technical field of valves, and in particular to a multifunctional beauty instrument proportional valve. Background Art

[0002] There are numerous beauty devices on the market, ranging from facials to hairdressing and body care. A search revealed patent application number 200910042346, which discloses a beauty device consisting of a microneedle roller and a handle. A liquid titration device is located between the roller and the handle. The device consists of a bottle holder with a liquid outlet and an air inlet, and a liquid burette. The outlet is connected to the burette, and the ratio of the outlet to the air inlet is 2:1 to 4:1. A control valve with a switch is built into the handle, connected by an air tube. The other end of the air tube is connected to the air inlet of the liquid titration device. This beauty instrument can control the outflow of nutrient liquid in the liquid titration device, and in conjunction with the use of a microneedle roller, it allows nutrient liquids such as essences to penetrate into the skin more effectively and be fully absorbed by the skin's epidermis, dermis, and subcutaneous tissue; when the control valve is in a closed state, due to the aperture ratio setting of the liquid outlet and the air inlet, the liquid in the liquid titration device will not flow back into the air inlet, thereby preventing damage to the beauty instrument.

[0003] A proportional valve is a hydraulic control device that replaces the original control components of conventional pressure, flow, and directional valves with a proportional solenoid. This allows for continuous and proportional remote control of the oil flow's pressure, flow, or direction based on an input electrical signal. Proportional valves generally feature pressure compensation, ensuring that output pressure and flow are unaffected by load variations. However, existing proportional valves often lack the ability to monitor air pressure in the air circuit in real time. They are unable to adjust air pressure promptly when pressure deviations occur, and their low accuracy makes them difficult to use. Therefore, we propose a multifunctional beauty instrument proportional valve to address these issues. Summary of the Invention
