Description

Technical Field

[0001] This utility model relates to the field of ophthalmic care technology, and in particular to an ophthalmic care cleaner. Background Technology

[0002] A search revealed that patent CN204446574U discloses an ophthalmic care cleaning device, comprising a water tank, a water pump, a head clamp, a bracket, a sprayer, and a drain pipe. The water tank, containing cleaning fluid, is connected to the water pump via an inlet hose. An outlet hose is provided at the other end of the water pump, and a T-junction is provided at the end of the outlet hose. A first outlet pipe and a second outlet pipe are respectively connected to the two outlets of the T-junction. The other end of the first outlet pipe is connected to the same side of the two sprayers, and the other end of the second outlet pipe is connected to the other side of the two sprayers. The sprayer consists of two identical spray pipes connected together to form an elliptical structure, and the two spray pipes are independent of each other. Several nozzles are provided on the inner side of each spray pipe.

[0003] In the prior art, including the aforementioned patent, when the cleaning solution is sprayed from a nozzle during eye cleaning, the high-speed liquid flow can cause mechanical irritation to the eyelids and conjunctival tissues, leading to eye discomfort or inflammatory reactions. At the same time, due to the overflow caused by the liquid flow impact, some cleaning solution is lost before it can effectively cover the target cleaning area, which not only increases the consumption of cleaning solution but also reduces cleaning efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an eye care cleaner that solves the technical problem of high cleaning fluid consumption leading to eye injuries from impact.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an eye care cleaner, comprising:

[0006] The goggles conform to the contours of the user's eyes, forming a sealed cleaning chamber;

[0007] A flow deflector is provided, which is horizontally positioned on top of the goggles, and the direction of the cleaning fluid inflow is the same as the direction of the flow deflector.

[0008] The flow-slowing blade has at least one set of blades hinged to the inner wall of the flow-dispersing tube. The gap between the flow-slowing blade and the flow-dispersing tube allows the flow-slowing blade to rotate. The bottom of the flow-dispersing tube is provided with a flow-controlling tube that faces in the same direction and has a gradually narrowing internal connection.

[0009] When the cleaning fluid is discharged into the flow-damping tube, the hinge point of the flow-slowing blade rotates to prolong the residence time of the cleaning fluid inside. The gradually narrowing channel in the flow-controlling tube allows the cleaning fluid to flow gently into the user's eye in an intermittent drip manner for eye cleaning.

[0010] Preferably, the inner wall of the turbulence pipe is provided with a spiral guide groove for the cleaning fluid to rotate and flow, and the pitch of the spiral guide groove is 0.5-1.5mm.

[0011] Preferably, the flow control tube has a tapered channel consisting of a tapered section, a flow stabilizing section, and a dripping section. The input end of the tapered section is connected to the outlet end of the flow turbulence tube, and its inner diameter decreases linearly along the fluid direction. The inner diameter of the flow stabilizing section remains constant. The end of the dripping section has at least one dripping hole for the cleaning fluid to be output in an intermittent dripping manner, and the diameter of the dripping hole is 0.5-2mm.

[0012] Preferably, the circumferential diameter formed when the slow-flow blade rotates is greater than the maximum diameter inside the gradually narrowing flow control tube.

[0013] Preferably, the top of the goggles is provided with an adjustment groove for the lateral reciprocating sliding of the deflector tube, and the deflector tube and the bottom of the adjustment groove are horizontally arranged.

[0014] Preferably, the top of the goggles is rotatably connected to a bidirectional threaded screw, and threaded blocks that can move relative to each other are threaded on both sides of the screw. A connecting rod that is fixed to the baffle tube is fixed on the side wall of the threaded block, and the connecting rod is horizontally set with the top of the baffle tube.

[0015] Preferably, the bottom of the goggles is provided with a circular absorbent cotton strip, and the bottom of the goggles has a circular groove for the circular absorbent cotton strip to be engaged and detached.

[0016] By employing the above technical solution, this utility model provides an eye care cleaner, which has at least the following beneficial effects:

[0017] 1. Due to the inclusion of a turbulence-disrupting tube, a flow-slowing vane, and a flow-controlling tube, this utility model allows the cleaning fluid to form a standing wave effect within the turbulence-disrupting tube through its internal structure and the flow-slowing vane, reducing the impact force. Furthermore, the gradually narrowing channel structure within the flow-controlling tube allows the cleaning fluid to gently flow into the user's eye in intermittent droplets for eye cleaning, thus solving the technical problem in the prior art where high consumption of cleaning fluid leads to eye injury due to impact force.

[0018] 2. Due to the design of the bidirectional threaded screw, threaded block, and connecting rod, when the bidirectional threaded screw is rotated, the threaded block on its outer wall will move relative to it, thereby driving the baffle tube to adjust the position of the bottom flow control tube. This allows the user to flexibly adjust the drip position of the cleaning fluid according to their own interpupillary distance to achieve the best cleaning effect. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 This embodiment proposes an eye care cleaner, comprising:

[0028] The goggles 1 conform to the contours of the user's eyes to form a sealed cleaning cavity. They are made of medical-grade silicone and have a wavy cross-section, which can adapt to different users' eye socket contours to form a negative pressure sealed cavity.

[0029] The top of the baffle tube 2 is fixedly connected to a water outlet hose, which is used in the prior art. The cleaning fluid is drawn out by a water pump at a suitable flow rate and transmitted to the baffle tube 2 through the water outlet hose. The baffle tube 2 is horizontally set on the top of the goggles 1. The inflow direction of the cleaning fluid is the same as the tube shape of the baffle tube 2. After the goggles 1 are worn on the user's eyes, the user lies flat. At this time, the baffle tube 2 is perpendicular to the eyeball, so that the cleaning fluid can drip vertically onto the eyeball, reducing waste.

[0030] The flow-slowing vane 3 has at least one set hinged to the inner wall of the flow-control tube 2. The gap formed between the flow-slowing vane 3 and the flow-control tube 2 allows the flow-slowing vane 3 to rotate. The gap provides mechanical tolerance space, allowing the flow-slowing vane 3 sufficient space to rotate when fluid impacts and enters, avoiding mechanical jamming caused by rigid collision. The inner wall of the flow-control tube 2 has a spiral guide groove 2a for the rotating flow of the cleaning fluid. The pitch of the spiral guide groove 2a is 0.5-1.5mm. The circumferential diameter formed by the flow-slowing vane 3 when rotating is larger than the maximum diameter of the tapered inner part of the flow-control tube 4.

[0031] Specifically, when the cleaning fluid enters the turbulence-prone pipe 2 at a suitable flow rate, the damping vanes 3 of the dynamic buffer mechanism rotate under the impact of the fluid, forming an adjustable angle of 15°-75° with the flow direction of the cleaning fluid. This allows a small portion of the cleaning fluid to be guided by the damping vanes 3 and discharged into the spiral guide channel 2a, enhancing the turbulence effect and converting the straight flow into spiral turbulence, thus improving the buffering efficiency of the damping vanes 3. Most of the cleaning fluid is guided by the damping vanes 3 and discharged into the bottom wall of the turbulence-prone pipe 2 to form a buffer, preventing the damping vanes 3 from directly introducing the cleaning fluid into the flow control pipe 4, thus converting linear kinetic energy into turbulent energy dissipation. The decelerated cleaning fluid forms a standing wave effect within the turbulence-prone pipe 2, achieving a residence time ≥1.2s, reducing the impact force.

[0032] The bottom of the turbulence-disrupting pipe 2 is provided with a flow control pipe 4 that faces in the same direction and has a gradually narrowing internal connection. The gradually narrowing channel inside the flow control pipe 4 consists of a narrowing section 4a, a flow stabilizing section 4b, and a dripping section 4c. The input end of the narrowing section 4a is connected to the outlet end of the turbulence-disrupting pipe 2, and its inner diameter decreases linearly along the fluid direction. The inner diameter of the flow stabilizing section 4b remains constant. At least one dripping hole 4d is provided at the end of the dripping section 4c for the cleaning liquid to be output in an intermittent dripping manner, and the diameter of the dripping hole 4d is 0.5-2mm.

[0033] Specifically, when the fluid passes through the flow control tube 4, the converging section 4a generates the Bernoulli effect to reduce the flow velocity; the stabilizing section 4b eliminates flow separation; and the dripping section 4c controls the output flow rate to 0.1-0.3 ml every 4-5 seconds, forming an intermittent, gentle dripping mode. After a drop of cleaning solution enters the user's eye, the user closes their eyes and blinks 2-3 times, allowing the cleaning solution to clean the eyeball. After blinking, the cleaning solution gradually slides down the facial contours, which takes 2-3 seconds. Once all the cleaning solution has slid down, a new drop of cleaning solution is applied to repeat the cleaning process. Through this cycle, mechanical stimulation of the eyelids and conjunctival tissue by the high-speed fluid flow can be prevented. At the same time, it can reduce the amount of cleaning solution that is not effectively covered in the target cleaning area and is lost, thus reducing the consumption of cleaning solution and improving cleaning efficiency.

[0034] The bottom of the goggles 1 is provided with a circular absorbent cotton strip 9, and the bottom of the goggles 1 is provided with a circular groove 10 for the circular absorbent cotton strip 9 to be snapped in and can be separated.

[0035] Furthermore, as the cleaning fluid slides down the contours of the user's face, the circular absorbent swab 9 quickly absorbs the liquid through capillary action. Its high absorbency ensures that the liquid does not overflow. After cleaning, the user can apply force along the axial direction of the circular groove 10 to pull out the old circular absorbent swab 9. The clearly elastic pressing assembly method facilitates the replacement and pressing in of the new circular absorbent swab 9.

[0036] Based on the above, when the cleaning fluid is discharged into the flow-dispersing tube 2, the hinge point of the flow-slowing vane 3 rotates to prolong the residence time of the cleaning fluid inside it, and the gradually narrowing channel in the flow-controlling tube 4 allows the cleaning fluid to flow gently into the user's eye in an intermittent drip manner for eye cleaning.

[0037] As a further embodiment of this utility model, the top of the goggle 1 is provided with an adjustment groove 5 for the lateral reciprocating sliding of the deflector tube 2, and the bottom of the deflector tube 2 and the adjustment groove 5 are horizontally arranged. The top of the goggle 1 is also rotatably connected to a bidirectional threaded screw 6, and threaded blocks 7 that can move relatively are threadedly connected to both sides of the screw 6. An external through groove is provided on the inner wall of the goggle 1 for the threaded blocks 7 to slide, which serves to limit the movement of the threaded blocks 7. A connecting rod 8 that is fixed to the deflector tube 2 is fixed on the side wall of the threaded block 7, and the connecting rod 8 and the top of the deflector tube 2 are horizontally arranged.

[0038] Furthermore, since users have different interpupillary distances, rotating the bidirectional threaded screw 6 causes the threaded block 7 on its outer wall to move relative to the user. This movement is achieved by adjusting the distance between the baffle tubes 2 via the connecting rod 8. The movement of the baffle tube 2 simultaneously moves the bottom control tube 4, allowing the position of the cleaning solution in the dripping section 4c to be flexibly adjusted according to the user's interpupillary distance to achieve the best cleaning effect.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
