Device for cleaning contact lenses

Abstract

The invention provides a device for cleaning contact lenses. The device for cleaning the contact lenses comprises a cleaning unit and a control unit, wherein the control unit is separably combined above the cleaning unit and comprises a shell, a circuit board, two conductive parts and an electrically starting part, wherein the circuit board is placed in the shell; the two conductive parts are electrically connected with the circuit board respectively; and the electrically starting part is electrically connected with the circuit board and is used for starting the conductive parts. The conductive parts can contact with a cleaning agent in the cleaning unit to switch on to form an electric loop so that substances adhered to the contact lenses can be taken away and cleaning operation is finished. When used, the device for cleaning the contact lenses has the advantages of no damage to electronic parts during overflow of the cleaning agent, good waterproof effect, no physical damage to the contact lenses, simple parts and low cost.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a contact lens cleaning device. Background technique [0002] Ultrasonic (Ultrasonic or Ultrasound) is defined as a sound that exceeds the hearing of human ears. Generally speaking, sound frequencies exceeding 16,000 Hz are considered to be ultrasonic waves. They can be used to clean the lenses of glasses, contact lenses, and waterproof watches. [0003] When ultrasonic waves are transmitted in water, when the transmission force exceeds the load range of water, a large number of tiny vacuum bubbles will be generated. When the vacuum bubbles explode, the local high pressure will take away the dirt on the surface of the lens, and at the same time produce very small vacuum bubbles. The water column impacts the surface of the lens to produce a cleaning effect, but the above-mentioned physical impact method is likely to affect the structure of the lens to a certain extent. [0004] The cleaning f...

However, according to the drinking water quality standard in Taiwan, China, the control value for effective chlorine removal is 0.2 to 1.0 mg / liter, and the residual chlorine exceeds the standard by 3 to 15 times. It will cause irreparable damage to the eyes and body, and seriously affect the health. If the restoration process is wrong again, the result is really unimaginable
