The method comprises a cleaning mode, wherein the cleaning mode comprises one or more times of vibration cleaning steps and flushing steps for the hard cornea contact lens, wherein the specific times of the vibration cleaning steps and the flushing steps can be set according to actual needs, and the combination of one vibration cleaning step and one flushing step can be realized, or the combination of multiple vibration cleaning steps and multiple flushing steps can be realized. Specifically, the vibration cleaning step is to clean the hard cornea contact lens through ultrasonic vibration, and the condition during vibration cleaning is that the hard cornea contact lens needs to be immersed in cleaning liquid, and at the moment, large blocks of proteins and stains on the surface of the hard cornea contact lens can be shaken loose or shaken off through ultrasonic vibration, so that the large blocks of proteins can be conveniently washed off the hard cornea contact lens in the subsequent washing step; the rinsing step is to rinse the surface of the hard cornea contact lens by spraying a cleaning liquid under high pressure, and protein and stains attached to the surface of the hard cornea contact lens can be rinsed off.

In this embodiment, the cleaning method for the hard contact lens is to use the cleaning instrument provided with the oscillation piece 8, the flushing pipeline 4 and the drainage pipeline 5, so that the hard contact lens can be cleaned in a mode of combining oscillation cleaning and flushing, in the cleaning process, firstly, proteins on the surface of the hard contact lens are loosened or shaken off through the oscillation cleaning, so that the flushing efficiency can be greatly improved, meanwhile, the cleaning time is shortened, the cleaning liquid is saved, and in addition, the cleanliness of the hard contact lens can be greatly improved, the better air permeability is kept, and the service life of the hard contact lens is prolonged.

In the present utility model, the washing liquid means physiological saline, and the waste liquid is physiological saline used in the washing process.

In a preferred embodiment, the step of shock cleaning comprises: the cleaning solution is sprayed to the hard cornea contact lens through the flushing pipeline 4, the quantity of the sprayed cleaning solution is determined by the capacity of the cleaning cavity 1 and the position height of the basket 2 in the cleaning cavity 1, the basket 2 is positioned in the middle of the cleaning cavity 1 under normal conditions, when the liquid level of the cleaning solution in the cleaning cavity 1 is not over the hard cornea contact lens, the flushing pump 9 stops working, meanwhile, the control mechanism starts the oscillating piece 8 to work, the hard cornea contact lens is subjected to ultrasonic oscillation cleaning, and after the ultrasonic oscillation is finished, the drainage pump 10 is started to discharge waste liquid. Through the vibration cleaning step, the large protein attached to the surface of the hard cornea contact lens can be shaken off or loose, so that a certain cleaning effect is achieved on one hand, and on the other hand, the loose protein is convenient to remove through the subsequent washing step.

In order to save the consumption of cleaning liquid, the cleaning cavity 1 is generally barrel-shaped, the diameter of the cleaning cavity is slightly larger than that of the basket 2, so that the basket 2 is not contacted with the cavity wall of the cleaning cavity 1, the height of the cleaning cavity is larger than twice the diameter of the basket 2, when the basket 2 is fixed in the cleaning cavity 1, the basket 2 is positioned in the middle of the cleaning cavity 1, and during cleaning, the consumption of cleaning liquid is saved, and stains caused by too low positions can be prevented from splashing back to the surface of the hard cornea contact lens.

When washing through ultrasonic oscillation, the vibration frequency of vibration piece 8 can directly influence the cleaning performance, generally speaking, the higher vibration frequency, the abluent effect can be better, but when the vibration frequency is too high, makes hard cornea contact lens produce the crackle easily, influences consumer's use. In a preferred embodiment, the oscillating frequency of the oscillating piece 8 is 100-115K, and in the oscillating frequency range, the oscillating piece has a good cleaning effect and does not damage the hard cornea contact lens.

In addition, the time of vibration cleaning can also influence the cleaning effect, and in general, the longer the time of vibration cleaning is, the better the cleaning effect can be. However, when the vibration cleaning reaches a certain period of time, the ultrasonic vibration is continued, the cleaning effect is not obviously improved, the energy consumption is improved, and the time consumption is high. In a preferred embodiment, when the oscillation frequency of the oscillation piece 8 is 100-115K, the duration of the ultrasonic oscillation is 2-3 min, so that the ultrasonic cleaning device has a better cleaning effect and has smaller time and energy consumption.

In the conventional device with vibration cleaning, the hard contact lens is horizontally placed on the tray, which can cause proteins or stains still deposited on the surface of the lens after vibration loosening, in the present utility model, the basket 2 is vertically inserted into the cleaning cavity 1, so that the lens is suspended in the cleaning cavity 1 along the vertical direction, and in the vibration cleaning process, the fallen proteins or stains can fall into the bottom of the cleaning cavity 1 and separate from the lens, thereby having a better cleaning effect. However, some of the seismous proteins remain attached to the lens surface. In a preferred embodiment, in order to promote separation of loose proteins from the lens, the oscillating plate 8 is operated, the rotating motor 3 is also activated, and the proteins are driven to fall off the lens surface by driving the basket 2 to rotate. In this embodiment, by rotating the basket 2, the lens can make a rotary motion relative to the cleaning liquid, and by the friction force between the water and the lens, part of the loose protein falls off, so as to improve the vibration cleaning effect.

In a preferred embodiment, in the vibration cleaning step, cleaning liquid can be sprayed through a flushing pump 9 to wash the hard cornea contact lens, protein and stains on the surface of the hard cornea contact lens can be removed in the spraying process, and when the water level in the cleaning cavity 1 does not pass through the basket 2, the flushing pump 9 is closed to stop flushing; starting the oscillating piece 8, oscillating and cleaning for 1 minute, then starting the rotating motor 3, enabling the hard cornea contact lens to fall off protein or stains on the surface of the hard cornea contact lens by rotating the lens while oscillating and cleaning, and after continuing cleaning for 1-2 minutes, closing the oscillating piece 8 and the rotating motor 3, and starting the drainage pump 10 to drain waste liquid in the cleaning cavity 1. In this embodiment, the cleaning effect is better by cleaning first, then vibrating and cleaning, and then vibrating and cleaning and rotating are combined to perform cleaning.

In a preferred embodiment, the flushing step comprises: the cleaning solution is sprayed onto the hard contact lens, the hard contact lens is rotated while being rinsed, and at the same time, the drain pump 10 is turned on to drain the waste liquid generated by rinsing. In this embodiment, the surface of the hard contact lens is flushed by water pressure with a certain pressure, so that the shaken loose proteins and stains fall off from the surface of the hard contact lens, and meanwhile, in the cleaning process, the rotating motor 3 rotates the basket 2 to rotate, so that the hard contact lens can be flushed from different angles, and the surface of the hard contact lens is cleaner.

In a further preferred embodiment, the flushing step comprises: firstly, the flushing pump 9 and the rotating motor 3 are started to spray cleaning liquid to the hard cornea contact lens, the hard cornea contact lens is rotated while being flushed, the cleaning liquid is prevented from passing through the net basket 2, then the drainage pump 10 is started, the net basket 2 is rotated while being flushed, meanwhile, waste liquid in the cleaning cavity 1 is discharged while the flushing pump 9 and the rotating motor 3 are stopped after the flushing pump 9 and the rotating motor are operated for a period of time, and the drainage pump 10 continues to operate until all waste liquid is discharged. In this embodiment, the rinse pump 9 works before the drain pump 10, so that a certain amount of cleaning liquid is stored in the cleaning cavity 1, and therefore, the rotating basket 2 can make the cleaning liquid in the cleaning cavity 1 form a vortex, and the vortex can make loose proteins or stains more easily fall off, and can also better remove proteins or stains in the air holes of the hard cornea contact lens, especially after the drain pump 10 is turned on (it is required that the power of the drain pump 10 is the same as that of the rinse pump 9), on one hand, the cleaning liquid is sprayed to wash the surface of the lens, on the other hand, the proteins and stains are removed from the surface of the lens by the rotating cleaning liquid, and on the other hand, the formed vortex can make the proteins and stains move downwards and be discharged, so that the cleaning liquid on the upper layer is cleaner, and the cleaning effect can be more efficient and better.

In a preferred embodiment, the output end of the flushing pipeline 4 is provided with two water spraying branch pipes, two opposite water spraying ports are arranged on the side wall of the cleaning cavity 1 corresponding to the basket 2, and the two water spraying ports are respectively connected with the two water spraying branch pipes, so that when flushing is performed, cleaning liquid is sprayed from two directions, the cleaning efficiency is higher, and when the rotating motor 3 drives the basket 2 to rotate, vortex is easier to form in the cleaning cavity 1, and the cleaning effect is better.

Because the flushing water pressure can directly influence the flushing effect in the flushing process, in general, the larger the water pressure is, the larger the impact force is, the better the flushing effect is, but the excessive water pressure can damage the hard cornea contact lens to cause the hard cornea contact lens to generate cracks. Therefore, in a preferred embodiment, the water pressure of the cleaning solution sprayed in the rinsing step is 18-22 kpa, and in this water pressure range, the rinsing effect is good and the hard corneal contact lens is not damaged.

In a preferred embodiment, in the flushing step, when the water pressure of the sprayed cleaning solution is 18-22 kpa, the working time of the flushing pump 9 is 20-30S, so that the cleaning effect is better, and the consumption of the cleaning solution is less.

In order to improve the cleanliness of the lens, in a preferred embodiment, the method comprises: the method comprises the steps of carrying out two times of vibration cleaning and two times of flushing on the hard cornea contact lens, and carrying out the vibration cleaning step and the flushing step at intervals, namely, the cleaning steps of the method are as follows in sequence: firstly, carrying out vibration cleaning, then washing, carrying out vibration cleaning after washing, and washing after vibration cleaning. By alternately carrying out vibration cleaning and flushing, the attached proteins and stains can be firstly shaken loose or shaken off, and then the shaken loose proteins and stains are flushed out by flushing, so that the hard cornea contact lens is clean. And through twice vibration washing and flushing, protein and stains hidden in the air holes of the hard cornea contact lens can be removed, so that the hard cornea contact lens keeps good air permeability, and the problem that the air permeability of the hard cornea contact lens is reduced due to the fact that the air holes are blocked by the protein and the stains in the air holes in the long-term use process is avoided, so that the service life of the lens can be prolonged.

Of course, for hard cornea contact lenses with different cleaning degrees, a mode of combining cleaning modes with different times can be adopted so as to ensure the cleaning efficiency and the cleaning degree of the hard cornea contact lenses.

In addition, since proteins or stains are inevitably attached to the outer surface of the cavity wall of the cleaning cavity 1 or the basket 2 during the cleaning process, these proteins or stains easily contaminate the hard contact lens at the next cleaning if the cleaning cavity 1 is not cleaned after the cleaning. In order to facilitate cleaning of the cleaning chamber 1 and the basket 2, in a preferred embodiment, the cleaning apparatus is further provided with a water storage tank 11, the water storage tank 11 is used for storing clean distilled water, mineral water or boiled water, and the water storage tank 11 is communicated with the cleaning chamber 1 through the flushing pipeline 4, so that water can be sprayed into the cleaning chamber 1 through the action of the flushing pipeline 4 to keep the cleaning chamber 1 clean.

It should be noted that, for the convenience of control, the input end of the flushing pipeline is provided with two branch pipes, two branch pipes are respectively connected with the cleaning solution tank 6 and the water storage tank 11, and a three-way valve 12 is arranged at the connection position of the two branch pipes and the flushing pipeline 4, and the three-way valve 12 is electrically connected with the control mechanism, and the communication state of the three-way valve can be controlled by the control mechanism.

The method further comprises a cleaning mode comprising rinsing the washing chamber 1 and basket 2 by means of a jet of water. In the specific implementation process, after the cleaning mode is started, the flushing pump 9, the rotating motor 3 and the drainage pump 10 are simultaneously started, the flushing pipeline 4 is communicated with the water storage tank 11 and the cleaning cavity 1, water is sprayed to the cleaning cavity 1, the rotating motor 3 simultaneously works when spraying water, so that the basket 2 rotates, at the moment, as no hard cornea contact lens exists in the basket 2, the outer surface and the inner part of the basket 2 can be better cleaned, and meanwhile, the sprayed water can flush the cavity wall of the cleaning cavity 1, so that proteins or stains attached to the cavity wall are flushed. By activating the cleaning mode, the basket 2 and the inner wall of the cleaning chamber 1 can be kept clean. In the cleaning mode, the working time periods of the flushing pump 9, the rotating motor 3 and the draining pump 10 can be set according to actual needs.

In a simple embodiment, the water storage tank 11 is not required, and the cleaning solution tank 6 is replaced by the water storage tank 11 or the cleaning solution in the cleaning solution tank 6 is replaced by clean water when the cleaning cavity 1 and the basket 2 need to be cleaned.
