Description

Pull formula contact lens nursing device

Technical Field

The utility model relates to the technical field of contact lens cleaning equipment, in particular to a drawing type contact lens nursing device.

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 contact lenses and scleral lenses has been an industrial problem, for example, hard contact lenses, and deposits of proteins, lipids, etc. or bacteria remain on 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.

Examples

The present embodiment provides a contact lens care device, which is mainly composed of a cover body 10, a base body 20, a brushing assembly 30, a storage device 40 and a driving mechanism.

As shown in fig. 1 to 3, 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. 4. 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 the brush 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. 3, the first brush head 31 and the second brush head 32 are shown schematically in the figure as being 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 80, such as a reducing motor, and a first driving gear 81 is sleeved on a main shaft of the first driving device 80, and the first driving gear 81 is meshed with the second driven gear 324, so that the first driving device 80 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 90, such as a reducing motor, and a second driving gear 91 is sleeved on a main shaft of the second driving device 90, and the second driving gear 91 is meshed with the first driven gear 313, so that the second driving device 90 drives the first brush head 31 to rotate under the gear transmission. As shown in fig. 3, the main body of the second driving device 90 is preferably fixedly mounted on the cover body upper cover 11 through a fixing support 92.

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 180 is rubbed. As shown in fig. 3, 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. 1 to 4. Like this, when taking down contact lens 180, the user can directly place on the flexible structure of brush head down, and need not overturn the direction of contact lens 180 again, also need not turn to when wearing contact lens 180 after wasing, can directly wear, the simple operation, and can promote user experience greatly. Meanwhile, the sewage on the contact lens 180 automatically flows away, so that no residual liquid is formed on the contact lens 180. 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. 4. The contact lens 180 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 180 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 sewage on the inner side of the contact lens 180 after cleaning, and the inner side of the contact lens 180 is provided with a reverse arc, which is relatively easy to collect dirt, so that the inner side of the contact lens 180 is a cleaning point, and the downward placement of the inner side of the contact lens 180 is more preferable.

As shown in fig. 5, two of said holding means 40 are schematically illustrated. Which are defined as a first storage means 41 and a second storage means 42, respectively. Of course, the number of the storage devices 40 is not limited to this, and may be any number, such as one, three or other, etc., and each of the storage devices 40 is respectively in communication with the inner cavity 23 of the base 20. Preferably, the storage device 40 is communicated with the inner cavity 23 of the base 20 through a pipeline. As shown in fig. 1 and 3, a notch is formed on the bottom side wall of the lower cover shell 12, and the pipe on the first storage device 41 is inserted between the lower cover shell 12 and the upper base shell 21 through the notch and is further communicated with the inner cavity 23 of the base 20, as shown in fig. 7, 10 and 11. And the pipeline on the second storage device 42 is communicated with the water outlet 25 on the upper shell 21 of the seat body and positioned at the bottom of the inner cavity 23. Preferably, the pipe of the storage device 40 is connected with a suction device 70 such as a water pump, for example, as shown in fig. 6 and 11, the pipe of the first storage device 41 is connected with a first suction device 71, the suction port of the first suction device 71 is communicated with the inner cavity 23 of the first storage device 41 through the pipe, and the discharge port is communicated with the inner cavity 23 of the base 20 through the pipe, so that, in a specific implementation, after the substances such as nursing liquid, physiological saline, cleaning liquid or clear water are added into the first storage device 41, the first suction device 71 can automatically add the liquid into the inner cavity 23 of the base 20. Similarly, the second suction device 72 is connected to the pipe of the second storage device 42, the outlet of the second suction device 72 is connected to the inner cavity 23 of the second storage device 42 through the pipe, and the suction port is connected to the inner cavity 23 of the base 20 through the pipe, so that in a specific implementation, substances such as dirty water or waste liquid in the inner cavity 23 of the base 20 can be automatically discharged into the second storage device 42. Of course, the communication mode between the storage device 40 and the inner cavity 23 of the base 20 is not limited to this, and other modes may be adopted, for example, a connection mode of matching a pipeline with a valve may be adopted, the storage device 40 for storing physiological saline, nursing liquid or clean water is disposed at a higher position, the storage device 40 for storing dirty water is disposed at a lower position, and automatic liquid filling or draining in the cleaning chamber can be realized by adjusting the valve to open or close under the action of gravity. When the storage device 40 is provided as one, the storage device 40 may be used for storing substances such as a care solution, a physiological saline, a cleaning solution, or clean water, or storing dirty water, and the suction direction of the suction device 70 may be set according to needs, so as to achieve the purpose of conveying the substances in the storage device 40 into the inner cavity 23 of the base 20 and/or conveying the substances in the inner cavity 23 of the base 20 into the storage device 40.

At least one first electrode member 50 and at least one second electrode member 60 are further disposed in the inner cavity 23 of the housing 20, and after the power is applied, polarities of the first electrode member 50 and the second electrode member 60 are opposite.

In this way, when the nursing device works, an electrolyte solution containing chloride ions such as nursing solution is added into the inner cavity 23 of the base 20, after the contact lens 180 to be cleaned is placed into the inner cavity 23 filled with the electrolyte solution containing chloride ions, the first electrode part 50 and the second electrode part 60 are respectively electrified, a positive electrode and a negative electrode are formed between the first electrode part 50 and the second electrode part 60 under a circuit loop formed by the electrolyte solution, a certain potential difference exists, tear proteins and other dirty matters attached to the surface of the contact lens 180 to be cleaned are charged in the electrolyte solution containing chloride ions, and under the action of the potential difference, the charged tear proteins and other dirty matters move towards an electrode position opposite to the electric property of the contact lens 180 to be separated from the contact lens 180, so that the contact lens 180 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.
