Description

Technical Field

[0001] The utility model relates to the technical field of contact lens cleaning, in particular to an intelligent megasonic wave cleaning instrument for contact lenses. Background Art

[0002] Contact lenses, also known as contact lenses, are lenses worn on the cornea to correct vision or protect the eyes. They are not only suitable for special patients with suspected keratoconus, large astigmatism, or extremely irregular corneal morphology after surgery, but are also suitable for controlling the progression of myopia in adolescents or children. They can correct refractive errors and have a good effect on vision correction. In addition, contact lenses can also increase aesthetics and comfort. However, when wearing contact lenses, the lenses are exposed to the external environment for a long time, causing foreign matter such as dust and oil to stick to the lenses. In addition, secretions on the cornea will also stick to the cornea. If you do not pay attention to hygiene when wearing contact lenses, it is easy to cause bacterial infection, which may cause conjunctivitis or keratitis. Therefore, the cornea needs to be cleaned and disinfected regularly.

[0003] In the prior art, ultrasonic and ultraviolet disinfection methods are mostly used to clean and disinfect contact lenses. The frequency of traditional ultrasonic cleaning transducers is between 20kHz and 100kHz. The cavitation effect is large in this frequency range, which may cause certain damage to the surface of the object during the cleaning process, and it is also difficult to remove impurity particles below 1 micron. Chinese patent CN219657966U discloses an intelligent ultrasonic cleaning box for contact lenses, including a shell, a cover, a filtering mechanism and a control panel. The shell and cover of the contact lens box are connected by a hinge. Repeated opening and closing of the cover will cause the hinge to break, resulting in poor sealing between the cover and the shell. When the cover is closed, it may also cause pinching injuries. In addition, there is no dust cover above the cleaning tank of the contact lens box, which makes it easy for dust to enter the cleaning tank, thereby causing contamination of the contact lenses. In addition, during the cleaning process, the care solution may overflow the cleaning tank due to ultrasonic vibration. After cleaning, tweezers are usually used to pick up the contact lenses in the cleaning tank. Since most contact lenses are transparent, it is inconvenient to check them during picking, resulting in difficulty in picking them up.

[0004] In order to solve these problems and ensure the cleanliness of contact lenses, the utility model provides an intelligent megasonic cleaning instrument for contact lenses to solve the problems. Utility Model Content

[0027] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0028] like Figure 1 As shown, an intelligent megasonic wave cleaning device for contact lenses includes a sterilization cover 1 and a main body device 2.

[0029] The sterilization cover 1 is located above the main device 2 and is used to seal the main device 2, which can isolate foreign matter such as dust from the outside from entering the main device 2, avoid contaminating the internal environment of the main device 2, and ensure the cleanliness of the interior of the main device 2; the sterilization cover 1 and the main device 2 are detachable, in order to facilitate cleaning of the sterilization cover 1 and the main device 2, especially when the sterilization cover 1 is repeatedly opened and closed, the sealing between the sterilization cover 1 and the main device 2 will not be destroyed, and the fingers will not be pinched when the sterilization cover 1 is closed.

[0030] like Figure 2 As shown, the sterilization cover 1 includes a sterilization upper cover 11, a sterilization circuit board 12 and a sterilization lower cover 13; a sterilization indicator mark 111 is provided on the upper surface of the sterilization upper cover 11, and the sterilization indicator mark 111 includes a silk screen and a light. The silk screen of the sterilization indicator mark 111 facilitates the placement of the sterilization cover 1 on the main device 2 in the correct position. When sterilization starts, the light of the sterilization indicator mark 111 is always on. After sterilization is completed, the light of the sterilization indicator mark 111 is off. Two ultraviolet sterilization lamp beads 13 are provided in the middle of the sterilization lower cover 13 1. The embodiment of the present application uses ultraviolet rays in the UVC band. Ultraviolet rays in this band not only have a better sterilization effect, but also have the weakest penetrating power compared to other bands. When the sterilization cover is attached to the main device, the ultraviolet rays in the UVC band generated by the ultraviolet sterilization lamp beads 131 will not harm the human body, and are safer to use; the sterilization circuit board 12 is fixed between the sterilization upper cover 11 and the sterilization lower cover 13. The sterilization circuit board 12 is used to control the on and off of the sterilization indicator 111 and the ultraviolet sterilization lamp beads 131.

[0031] like Figure 1As shown, the main device 2 is provided with a cleaning device 21 and a vibrator 22; the cleaning device 21 is used to clean the contact lenses and prevent the contact lenses from being contaminated. The cleaning device 21 is located in the middle part of the main device 2, and includes a cleaning tank 211, a threaded cover 212 and a single silicone basket 213. The number of cleaning tanks 211 is set to two, which are used to place and clean the contact lenses separately to avoid cross-infection between the two contact lenses; the threaded cover 212 is located above the cleaning tank 211, and the threaded cover 212 can be connected to the cleaning tank 211 through threaded engagement. A plurality of anti-slip grooves are evenly distributed on the side of the threaded cover 212 to increase the friction between the fingers and the threaded cover, facilitating the loosening and tightening of the threaded cover 212. The threaded cover 212 is used to prevent dust from entering the cleaning tank, adding an extra line of protection for the cleaning of the contact lenses, and during the cleaning process, avoiding the overflow of the care solution caused by the vibration generated by the megasonic waves.

[0032] like Figure 1 and Figure 4 As shown, a single silicone basket 213 is placed inside the cleaning tank 211. The single silicone basket 213 has a hollow structure. A handle 214 is provided on one side of the upper edge of the single silicone basket 213, and an edge 215 is provided on the other side of the upper edge of the single silicone basket 213. When cleaning contact lenses, the single silicone basket 213 is held by the handle 214 and placed inside the cleaning tank 211. The edge 215 of the single silicone basket 213 is provided to prevent the single silicone basket 213 from tipping over when placed in the cleaning tank 211. The contact lenses are placed in the single silicone basket 213. After cleaning, the single silicone basket 213 is taken out by holding the handle 214 of the single silicone basket 213. Since most contact lenses are transparent, it is inconvenient to see when picking them up with tweezers, making it difficult to pick up the contact lenses. The design of the single silicone basket 213 makes it easy to take out the contact lenses. The vibrator 22 is located below the cleaning device. The megasonic waves generated by the vibrator 22 are converted into mechanical vibrations to clean dust and other foreign matter from the contact lenses.

[0033] It should be noted that the frequency range of the megasonic waves generated by the vibrator 22 is 2.4MHz±20%. The frequency of traditional ultrasonic cleaning transducers is between 20kHz-100kHz. The cavitation effect in this frequency range is large, which can damage precision components and is also difficult to remove impurity particles smaller than 1 micron. Ultrasonic waves at megahertz frequencies are often referred to as "megasonic waves" in the industry, so ultrasonic cleaning within this frequency range is also called megasonic cleaning. The present invention adopts a megasonic cleaning method. Due to the extremely low cavitation effect, the megasonic cleaning process will not damage the contact lenses, and can effectively solve the problems of corrosion or damage caused by cleaning. It can also clean away micron and submicron impurity particles on the surface of the contact lenses, improving the cleaning efficiency of the contact lenses.

[0034] In some embodiments, both the sterilization lower cover 13 and the main body 2 are provided with magnets, and the polarities of the magnets of the sterilization lower cover 13 and the main body 2 are opposite. The sterilization cover 1 is placed on the main body 2, and the sealing between the sterilization cover 1 and the main body 2 is improved by the mutual attraction of magnets of different polarities; in other embodiments, the polarity of the magnet can be ignored during the assembly process by setting any magnet in the sterilization lower cover 13 or the main body 2 to other magnetic materials.

[0035] like Figure 1 and Figure 3 As shown, the main device 2 also includes a probe 23, a start button 24 and a power charging port 25; the probe 23, the start button 24 and the power charging port 25 are all electrically connected to the main device 2. The probe 23 is used to detect whether the sterilization cover 1 is in contact with the main device 2. When the sterilization cover 1 is placed on the main device 2, the probe 23 detects that the sterilization cover 1 is in contact with the main device 2, and the sterilization circuit board 12 controls the light of the sterilization indicator 111 to be always on and the ultraviolet sterilization lamp beads 131 to be always on. When the sterilization cover 1 is removed, the probe 23 cannot detect the sterilization cover 1, and the sterilization circuit board 12 does not work, so the sterilization operation will not be performed. That is, only when the sterilization cover 1 is covered, the ultraviolet sterilization lamp beads 131 will start working, ensuring the safety of the use process; the start button 24 is a one-touch button, which is simple and convenient to operate.

[0036] In some embodiments, the power charging port 25 adopts a magnetic charging structure. The magnetic charging method allows the data cable to be plugged and unplugged with one hand, eliminating the tedious plugging and unplugging operations. In addition, the magnetic charging method has good waterproof performance. The utility model can be directly cleaned with water, which not only ensures the cleanliness of the utility model, but also does not cause secondary pollution to the contact lenses.

[0037] In some embodiments, the four sides of the main body device 2 are provided with rounded corners, and the four corners of the sterilization cover 1 are provided with rounded corners, so that the cleaning device feels smooth and avoids scratches, and has good overall aesthetics.

[0038] The working process of this utility model:

[0039] 1. Hold the handle 214 of the single silica gel basket 213 and place the single silica gel basket 213 inside the cleaning tank 211;

[0040] 2. Pour an appropriate amount of care solution into the cleaning tank 211 and place the left and right contact lenses into the corresponding single silicone baskets 213;

[0041] 3. Cover with threaded cap 214 and tighten;

[0042] 3. Press the start button 24, the indicator light of the start button 24 changes breathing, and cleaning begins. When the cleaning time is reached and the cleaning is completed, the indicator light goes out and the cleaning is completed.

[0043] 4. Hold the handle 214 of the single silica gel basket 213 to take out the single silica gel basket 213, and then take out the cleaned lens;

[0044] 5. Press the start button 24 and cover the sterilization cover 1. After the probe 23 detects the sterilization cover 1, the sterilization circuit board 12 starts working, the ultraviolet sterilization lamp beads 131 start working, the light of the sterilization indicator mark 111 is always on, and the indicator light of the start button 24 flashes quickly. When the disinfection time is reached, the sterilization circuit board 12 stops working.

[0045] Even though the present invention has been described with reference to specific exemplary embodiments thereof, many different alternatives, modifications, etc. will become apparent to those skilled in the art. It should also be noted that the circuit arrangement and identification detection methods within the apparatus of the present invention may be omitted, exchanged, or arranged in various ways, while the structure of the device is still capable of performing the functionality of the present invention.
