Description

Contact lens washs subassembly and contact lens nursing instrument

Technical Field

The utility model relates to the technical field of contact lens cleaning equipment, in particular to a contact lens washing assembly and a contact lens nursing instrument.

Background

Contact lenses include soft contact lenses and hard contact lenses. Rigid contact lenses in turn include rigid corneal contact lenses, scleral lenses, and the like.

The cleaning of hard contact lenses and scleral lenses has been an industrial problem, taking hard contact lenses as an example, and deposits of proteins, lipids and the like or bacteria remain on the hard contact lenses during daily use. The hard cornea contact lens material structure is provided with a large number of oxygen permeation holes which cannot be seen by naked eyes, proteins, lipids and other sediments can easily permeate into the oxygen permeation holes, so that the oxygen permeation rate of the lens is reduced, further symptoms such as cornea hypoxia and edema are caused, and the problems such as cornea damage, bacterial infection, cornea inflammation and even vision damage are caused in serious cases. Meanwhile, grease dirt, bacteria and the like may exist on the surface of the contact lens in daily use, and the health of the contact lens is affected.

In order to remove protein deposition on the surface of the contact lens, the traditional cleaning method is to manually match with a nursing solution to physically rub the lens or use a chemical active agent to soak the lens so as to achieve the purpose of removing protein, but experimental data at home and abroad or user feedback prove that the protein removing effect of the means is very small, and in addition, in the process of rubbing fingers, particularly in the process of rubbing hard cornea contact lenses, the lens is easily scratched and damaged, and in addition, the finger rubbing cleaning mode is too complicated, so that the user experience is not facilitated.

Meanwhile, the contact lens is also possibly contaminated and bred with bacteria in the use process, and how to conveniently remove the bacteria is also a troublesome matter.

For this reason, the applicant creatively applies the electrophoresis dissociation technique to the hard contact lens care, and electrophoresis, which is the short term of electrophoresis phenomenon, refers to the phenomenon that charged particles move towards an electrode opposite to the charged particles under the action of an electric field. A technique of achieving separation by using a difference in the moving speed of charged particles in an electric field is called an electrophoresis technique. Protein Electrophoresis (SPE) is a protein analysis technique, in which proteins are negatively or positively charged in a buffer, and move to the anode or cathode in an electric field, called electrophoresis, and different protein molecules have different electrophoretic mobilities. Electrolysis (Electrolysis) is a process in which an electric current is passed through an electrolyte solution or a molten electrolyte (also called an electrolyte solution) to cause oxidation-reduction reactions at a cathode and an anode, and an electrochemical cell can undergo an Electrolysis process when a direct current voltage is applied thereto. The applicant can realize the technical effects of protein removal and sterilization to a certain extent by adopting an electrophoresis and electrolysis mode.

Although the electrophoresis dissociation technology can remove proteins, bacteria and the like on the hard cornea contact lens, for some lipids or precipitates with larger particles such as eye droppings and the like, the cleaning can be realized by rubbing the hard cornea contact lens with hands, or by increasing current or prolonging the cleaning time, however, the oxidation environment can be too strong due to the increase of current or the prolonged cleaning time, and the deformation of the material of the hard contact lens or other problems affecting the safe use can be caused due to the too strong oxidation environment.

Therefore, the prior art is difficult to achieve that the hard contact lens is not damaged, and the hard contact lens can be well cleaned of the sediment and grease with larger lipid or particulate matters. In combination with the above-mentioned technical problems, new innovations are necessary.

Detailed Description

In order to further describe the technical means and effects adopted for achieving the preset aim of the utility model, the following detailed description is given below of the specific implementation, structure, characteristics and effects according to the utility model with reference to the attached drawings and the preferred embodiments.

The present embodiment provides a contact lens care instrument, which is mainly composed of a cover body 10, a base body 20, a brushing assembly 30 and a driving mechanism, as shown in fig. 1 to 4.

As shown in fig. 2 to 4, the base 20 has an inner cavity 23, i.e., a cleaning chamber. The seat 20 has an opening at one side, i.e., at an upper side, which communicates with the inner cavity 23. And the cover 10 is disposed at an opening side of the base 20, i.e., above the base 20. Two scrubbing assemblies 30 are schematically illustrated, but in practice, the number of scrubbing assemblies 30 is not limited and may be any number.

The scrubbing assembly 30 is comprised primarily of a first brush head 31 and a second brush head 32, as shown in fig. 5. The first brush head 31 and the second brush head 32 are made of soft material. The first brush head 31 is disposed on a side of the cover body 10 facing the base body 20, the second brush head 32 is disposed in the inner cavity 23, the first brush head 31 and the second brush head 32 of each brushing assembly 30 are correspondingly matched, and the first brush head 31 and the second brush head 32 can relatively rotate under the driving of the driving mechanism. As shown in fig. 4, the first brush head 31 and the second brush head 32 are both rotatably disposed. The base 20 is composed of a base upper shell 21 and a base lower shell 22, the base upper shell 21 is clamped above the base lower shell 22, and the inner cavity 23 is arranged on the base upper shell 21. A first accommodating cavity 24 is formed between the upper housing 21 and the lower housing 22. The second brush head 32 is rotatably connected with the upper housing 21 through a second rotating shaft 323. One end of the second rotating shaft 323 extends into the first accommodating cavity 24, and a second driven gear 324 is sleeved on the second rotating shaft 323 in the first accommodating cavity 24. The driving mechanism includes a first driving device 60, such as a reducing motor, and a first driving gear 61 is sleeved on a main shaft of the first driving device 60, and the first driving gear 61 is meshed with the second driven gear 324, so that the first driving device 60 drives the second brush head 32 to rotate under gear transmission.

The cover body 10 is composed of a cover body upper cover 11 and a cover body lower shell 12, the cover body upper cover 11 is clamped at one side of the cover body lower shell 12 far away from the base body 20, and a second accommodating cavity 13 is formed between the cover body upper cover 11 and the cover body lower shell 12. The first brush head 31 is rotatably connected with the cover lower shell 12 through a first rotating shaft 312. One end of the first rotating shaft 312 extends into the second accommodating cavity 13, and a first driven gear 313 is sleeved on the first rotating shaft 312 in the second accommodating cavity 13. The driving mechanism includes a second driving device 70, such as a reducing motor, and a second driving gear 71 is sleeved on a main shaft of the second driving device 70, and the second driving gear 71 is meshed with the first driven gear 313, so that the second driving device 70 drives the first brush head 31 to rotate under the gear transmission. As shown in fig. 4, the main body of the second driving device 70 is preferably fixedly mounted on the cover body upper cover 11 through a fixing support 72.

Of course, the above is only a preferred embodiment, and in the specific implementation, the first brush head 31 and the second brush head 32 may be driven by other modes, not limited to a motor driving gear, and in order to achieve the relative rotation between the first brush head 31 and the second brush head 32, the rotation directions between the first brush head 31 and the second brush head 32 may be opposite, or a certain rotation speed difference may exist between the two. Of course, in the implementation, only one of the first brush head 31 and the second brush head 32 may be rotatable, and the relative rotation between the two brush heads may be achieved.

Preferably, the first brush head 31 is configured as a brush head having an arc-shaped groove shape, and the second brush head 32 is configured as a brush head having an arc-shaped protrusion shape. It is further preferred that the side of the first brush head 31 facing the second brush head 32 is a flexible groove structure, and the side of the second brush head 32 facing the first brush head 31 is a flexible protrusion structure. For example, a plurality of first flexible structures 311 are disposed on a side of the first brush head 31 facing the second brush head 32, and a plurality of second flexible structures 321 are disposed on a side of the second brush head 32 facing the first brush head 31. The first flexible structure 311 and/or the second flexible structure 321 are preferably made of soft materials such as silicone. The soft material such as silica gel can well protect the lens when the contact lens 90 is rubbed. As shown in fig. 4, the first brush head 31 and the second brush head 32 are respectively formed by a brush head body and a silicone sleeve sleeved on the brush head body, and the first flexible structure 311 or the second flexible structure 321 is a columnar structure extending out of the silicone sleeve. The heights of the first flexible structures 311 are gradually increased from the middle position of the first brush head 31 to the periphery so as to form a groove shape; the heights of the second flexible structures 321 decrease from the middle position of the second brush head 32 to the periphery to form a convex shape, as shown in fig. 2 to 5. Therefore, when the contact lens 90 is taken down, the user can directly put on the flexible structure of the lower brush head without turning the direction of the contact lens 90, and the user can directly wear the contact lens 90 after wearing the contact lens 90 after cleaning without turning the contact lens, so that the operation is convenient and fast, and the user experience can be greatly improved. At the same time, the sewage on the contact lens 90 automatically flows away, and no liquid residue is formed on the contact lens 90. Further, a protruding limiting structure 322 is further disposed on a side of the second brush head 32 facing the first brush head 31, as shown in fig. 5. The contact lens 90 can be placed in a space surrounded by the second brush head 32 and the limiting structure 322 thereof and the first brush head 31, and the limiting structure 322 can limit the contact lens 90 from sliding out of the second brush head 32. The limiting structure 322 is made of soft materials, for example, the limiting structure 322 can also be a plurality of raised flexible columns extending out of the silica gel sleeve, and compared with the flexible structure, the strength of the limiting structure is larger, a certain limiting effect can be achieved, the stability of the lens placement position is ensured, and of course, the limiting structure 322 can also be other structures, such as a flexible blocking wall and the like.

Of course, the first brush head 31 may be configured as a brush head having an arc-shaped protrusion shape, and the second brush head 32 may be configured as a brush head having an arc-shaped groove shape. However, this embodiment may result in a residual amount of waste water on the inner side of the contact lens 90 after cleaning, and the inner side of the contact lens 90 is provided with a reverse arc, which is relatively easy to collect dirt, so that the inner side of the contact lens 90 is a cleaning point, and the downward placement of the inner side of the contact lens 90 is more preferable.

The first brush head and the second brush head can also be made of flexible silica gel materials to form bulges and grooves, a plurality of brush head parts like toothbrush bristles are not arranged, one brush head with a flexible bulge structure simulates the fingers of a person, and the other brush head with a flexible groove structure simulates the palm of the person, so that the assembly simulates the hands of the person to rub when working. An alternative embodiment is that the surfaces of the flexible raised structure brush head and the flexible recessed structure brush head also simulate the fingertips of a human being with fingerprint-like microprotrusions for better cleaning.

One embodiment of the brushing assembly is that the upper brush head is in a groove shape, and the lower brush head is in a convex structure, so that the reflective arc area and the inner side area of the contact lens are not easy to collect dirt in the cleaning process, and meanwhile, the process of taking and placing the contact lens from eyes is facilitated, and the human engineering is met.

At least one first electrode member 40 and at least one second electrode member 50 are also disposed in the cavity 23 of the housing 20, and after being energized, the polarities of the first electrode member 40 and the second electrode member 50 are opposite. As shown in fig. 2 and 3, the first electrode part 40 and the second electrode part 50 are respectively formed of sheet-shaped conductive plate structures, and are respectively disposed on two side walls of the inner cavity 23 of the housing upper case 21, one of which serves as a positive electrode, and the other serves as a negative electrode. In this way, when the nursing instrument works, electrolyte solution containing chloride ions such as nursing solution is added into the inner cavity 23 of the base 20, after the contact lens 90 to be cleaned is placed into the inner cavity 23 filled with the solution containing chloride ions, the first electrode part 40 and the second electrode part 50 are respectively electrified, a positive electrode and a negative electrode are formed between the first electrode part 40 and the second electrode part 50 under a circuit loop formed by the electrolyte solution, a certain potential difference exists, tear protein and other dirty matters attached to the surface of the contact lens 90 to be cleaned are charged in the solution containing chloride ions, and under the action of the potential difference, the charged tear protein and other dirty matters move towards an electrode position opposite to the electric property of the contact lens 90 to be separated from the contact lens 90, so that the contact lens 90 is cleaned; the chloride ions in the electrolyte solution move toward the positive electrode and the lost electrons are oxidized to chlorine gas, which dissolves in the electrolyte solution to generate hypochlorous acid. Hypochlorous acid can slowly undergo self redox reaction to decompose, and each hypochlorous acid molecule can absorb electrons during decomposition (hypochlorous acid is taken as a strong oxidant and can absorb electrons of surface proteins of microbial cell walls, so that functional proteins of microbial surfaces are oxidized, and the microorganisms are finally deactivated due to incapability of taking nutrition, incapability of normal metabolism and stopping splitting, so that the effect of sterilization and disinfection is finally achieved), so that the aim of sterilization is fulfilled, and hydrogen ions, chlorine ions and oxygen are dissociated. Hypochlorous acid can act on cell walls and virus shells in the sterilization and virus killing processes, has small hypochlorous acid molecules and no charge, can permeate into bacteria (viruses) bodies, and has oxidation reaction with organic macromolecules such as bacteria (viruses) body proteins, nucleic acids, enzymes and the like, so that pathogenic microorganisms are killed.

Preferably, a first conductive element 80, such as a conductive probe, is disposed at the upper end of the base 20 corresponding to the first electrode part 40 and the second electrode part 50, respectively. And another second conductive element (not shown) is correspondingly disposed on the cover 10, and a circuit board for supplying power to the first electrode part 40 and the second electrode part 50 may be disposed outside the base 20, for example, a housing may be clamped at the upper end of the cover upper cover 11, and the circuit board may be disposed in the housing, so as to connect the second conductive element and the circuit board. When the cover 10 is engaged with the base 20, the first conductive element 80 contacts with the corresponding second conductive element, so that the circuit board can supply power to the first electrode part 40 and the second electrode part 50.
