Description

Technical Field

[0001] This utility model relates to the field of contact lens hydration cleaning, and more specifically, it relates to an automatic contact lens hydration cleaning device. Background Technology

[0002] Hydration cleaning of contact lenses refers to the process of hydrating and expanding dry contact lenses produced through polymer polymerization with water, thereby removing surface impurities and creating wearable soft contact lenses.

[0003] Currently, the hydration cleaning of dry contact lenses mostly relies on manual operation, which is not only labor-intensive but also difficult to guarantee the cleaning effect. In addition, manual operation can easily introduce impurities, affecting wearing safety. Therefore, hydration cleaning devices are often used for cleaning. However, most existing hydration cleaning devices lack convenient on / off control mechanisms. When using them, the hydration cleaning equipment on the device must be turned on manually, which not only increases the number of steps but also leads to the waste of resources due to forgetting to turn off the hydration cleaning equipment.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes an automatic hydration cleaning device for contact lenses. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic hydration cleaning device for contact lenses.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic hydration cleaning device for contact lenses, comprising a hydration cleaning tank with an opening on one side, and a hydration cleaning device disposed on the top of the hydration cleaning tank. One side of the hydration cleaning tank is connected to a side door of the tank via a track assembly, which maintains the linear movement of the side door relative to the hydration cleaning tank. A spring switch for driving the hydration cleaning device is installed on the opening surface of the hydration cleaning tank. When the side door is pushed against the side of the hydration cleaning tank, the spring switch is squeezed to open the hydration cleaning device; otherwise, it is closed. A contact lens holder for placing dry contact lenses is installed on the side door.

[0007] Preferably, the four corners of the opening of the water-based cleaning tank are provided with circular grooves, and the center of the circular groove is connected to a circular block that can extend from and into the circular groove via a telescopic rod. A highly elastic spring is installed between the inner surface of the circular groove and the back of the circular block.

[0008] Preferably, the top of the hydration cleaning tank is equipped with a water inlet pipe connected to the hydration cleaning equipment, and the bottom of the hydration cleaning tank is provided with multiple drain pipes equipped with valves.

[0009] Preferably, a sealing gasket is provided around the opening on the opening surface of the hydration cleaning tank, which can effectively improve the sealing between the side door of the tank and the hydration cleaning tank, and prevent the cleaning liquid from leaking or splashing out during the hydration cleaning process.

[0010] Preferably, the track assembly includes multiple guide rails A fixed to the back of the water-based cleaning tank for sliding of the slider A, and the side ends of the slider A are all fixed to the side door of the tank via connecting rods.

[0011] Preferably, a fixing component is also installed between the water-based cleaning tank and the side door of the tank to fix the two together when the side door is pressed against the side of the water-based cleaning tank.

[0012] Preferably, a cylindrical through slot seat is fixedly connected to the side end of the water-based cleaning tank, a cylindrical block capable of passing through the cylindrical through slot seat is fixedly connected to the side end of the tank side door, a guide rail B for sliding slider B is fixedly connected to the surface of the cylindrical block, a blocking plate is fixedly connected to the side end of slider B, a magnet A is fixedly connected to the top of the blocking plate, and a magnet B that attracts magnet A is fixedly connected to the part of the cylindrical block above the guide rail B.

[0013] Preferably, the bottom of the water-based cleaning tank is fixedly connected to two support plates, and the bottom of the support plates is welded to a base. The support plates support the base and the water-based cleaning tank at a certain distance, which facilitates the connection between the drain pipe and the external drain pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model realizes the automatic opening and closing of the hydration cleaning equipment during the hydration cleaning process of dry contact lenses through components such as track assembly and spring switch, which simplifies the operation process and avoids resource waste, thereby solving the problem in the background technology that not only increases the number of usage steps, but also causes resource waste due to forgetting to turn off the hydration cleaning equipment;

[0016] 2. This utility model allows workers to take their hands off the water-based cleaning tank when it is closed by fixing components on the side door, thus improving ease of use;

[0017] 3. When the fixing of the water-based cleaning tank and the side door is released, the high-elasticity spring will use its rebound force to push the circular block to move the side door a certain distance away from the water-based cleaning tank, so that it will no longer squeeze the spring switch, thus avoiding the staff forgetting to pull the side door, which would cause the device to continue to operate and waste resources.

[0029] like Figure 1-6As shown, this utility model provides an automatic hydration cleaning device for contact lenses, including a hydration cleaning tank 1 with an opening on one side, and a hydration cleaning device 2 disposed on the top of the hydration cleaning tank 1. One side of the hydration cleaning tank 1 is connected to a side door 4 via a track assembly 3, which maintains the linear movement of the side door 4 relative to the hydration cleaning tank 1. A spring switch 5 is installed on the opening surface of the hydration cleaning tank 1 to drive the hydration cleaning device 2. When the side door 4 is pushed against the side of the hydration cleaning tank 1, the spring switch 5 is squeezed to open the hydration cleaning device 2 (at this time, the hydration cleaning tank 1 is closed), and vice versa, it is closed. Contact lenses for placing dry contact lenses are installed on the side door 4. The placement rack 16 and the opening of the hydration cleaning tank 1 are surrounded by a sealing gasket 6. The top of the hydration cleaning tank 1 is equipped with a water inlet pipe 11 that is connected to the hydration cleaning equipment 2. The bottom of the hydration cleaning tank 1 is equipped with multiple drain pipes 12 with valves. The water inlet pipe 11 is connected to an external water supply pipe for supplying water to the hydration cleaning equipment 2. The drain pipes 12 are connected to an external drainage pipe for draining the wastewater after hydration cleaning in the hydration cleaning tank 1. The valves on the drain pipes 12 are opened and closed at appropriate times to ensure that there is sufficient water in the hydration cleaning tank 1 to contact the dry contact lenses (soaking the dry contact lenses to ensure full contact with water and achieve full hydration and expansion).

[0030] Furthermore, support plates 14 are fixedly connected to both sides of the bottom of the water-based cleaning tank 1, and a base 15 is welded to the bottom of the support plate 14. The support plate 14 supports the base 15 and the water-based cleaning tank 1 at a certain distance, which facilitates the connection between the drain pipe 12 and the external drain pipe.

[0031] When it is necessary to hydrate and clean dry contact lenses, the side door 4 of the case is pulled open in a straight line via the track assembly 3, thereby pulling the contact lens holder 16 on the side door 4 out of the hydration cleaning case 1. Then, the dry contact lenses that need to be hydrated and cleaned are placed on the contact lens holder 16. Subsequently, the side door 4 is pushed to move in a straight line along the track assembly 3 and press against the side of the hydration cleaning case 1, closing the water pipe cleaning case 1 (the opening is sealed). At this time, the side door 4 will press the spring switch 5 on the opening surface of the hydration cleaning case 1. After the spring switch 5 is triggered, it drives the top hydration cleaning device 2 to open (at the same time, the sealing gasket 6 on the side of the hydration cleaning case 1 is also compressed, which can effectively improve the connection between the side door 4 and the hydration cleaning device 2). (The airtight seal between the washing tank 1 and the water tank prevents water leakage or splashing during the hydration cleaning process.) The hydration cleaning equipment 2 begins to perform hydration cleaning on the dry contact lenses placed on the contact lens holder 16 inside the hydration cleaning tank 1. After cleaning is completed, the side door 4 of the tank is opened to remove the hydration-cleaned soft contact lenses. At the same time, the spring switch 5 is no longer squeezed, and the built-in spring of the spring switch 5 will automatically pop open, and the hydration cleaning equipment 2 will then shut down. This achieves automatic opening and closing of the hydration cleaning equipment 2, simplifying the operation process and avoiding resource waste (the hydration cleaning tank 1 is transparent, making it convenient for staff to observe the hydration cleaning of the dry contact lenses).

[0032] The principle of spring switch 5 is based on the elastic deformation and reset characteristics of a spring to control the on / off state of the circuit. When an external force is applied to the spring (compression), the spring deforms, causing the connected conductive parts (such as metal plates or contacts) to move, thereby changing the connection state of the circuit. If the contacts that were originally open make contact due to the spring deformation, the circuit is connected and the switch is in the "open" state; if the contacts that were originally in contact separate due to the spring deformation, the circuit is broken and the switch is in the "closed" state. When the external force is removed, the spring returns to its original shape due to its elasticity, the conductive parts also reset, and the circuit state switches again. This cycle repeats to achieve the switching function, which is the current technology.

[0033] The track assembly 3 includes multiple guide rails A301 fixed to the back of the water-based cleaning tank 1 for sliding of the slider A302. The side ends of the slider A302 are all fixed to the side door 4 of the tank via connecting rods 303. That is, when the side door 4 of the tank is pulled back and forth, it will drive the slider A302 to slide back and forth along the guide rails A301 via the connecting rods 303 to maintain the linear movement of the side door 4 relative to the water-based cleaning tank 1.

[0034] Furthermore, a matching fixing component 13 is installed between the water-based cleaning tank 1 and the side door 4 to secure them together when the side door 4 is pressed against the side of the water-based cleaning tank 1. This allows the operator to take their hands off the tank when the side door 4 closes the water-based cleaning tank 1, improving ease of use. The specific structure of the fixing component 13 is as follows: A cylindrical through-slot seat 1301 is fixedly connected to the side of the water-based cleaning tank 1; a cylindrical block 1302 that can pass through the cylindrical through-slot seat 1301 is fixedly connected to the side of the side door 4; a guide rail B1303 for sliding the slider B1304 is fixedly connected to the surface of the cylindrical block 1302; a baffle plate 1305 is fixedly connected to the side of the slider B1304; a magnet A1306 is fixedly connected to the top of the baffle plate 1305; and a magnet A1306 is fixedly connected to the cylindrical block 1302 above the guide rail B1303. Magnets A1306 and B1307 attract each other. When the water-cleaning tank 1 is closed by pressing it against the side end of the water-cleaning tank 1, the cylindrical block 1302 is inserted into the cylindrical through slot seat 1301. The baffle plate 1305 extends from the other side of the cylindrical through slot seat 1301. Then, the baffle plate 1305 is pulled downward, causing magnets A1306 and B1307 to separate and press the baffle plate 1305 against the other side of the cylindrical through slot seat 1301, thereby restricting the movement of the side door 4. Conversely, pushing the baffle plate 1305 upward causes magnets A1306 and B1307 to come into contact. The contact between the two will form a certain attraction, thereby fixing the position of the baffle plate 1305. At this time, the baffle plate 1305 no longer presses against the other side of the cylindrical through slot seat 1301, and the side door 4 can be pulled normally.

[0035] Finally, this utility model also provides circular grooves 7 at the four corners of the opening of the water-based cleaning tank 1. The center of the circular groove 7 is connected to a circular block 9 that can extend into or out of the circular groove 7 via a telescopic rod 8. A high-elasticity spring 10 is installed between the inner surface of the circular groove 7 and the back of the circular block 9. That is, when the water-based cleaning tank 1 is closed by pressing it against the side, the circular block 9 will be squeezed and pressed into the circular groove 7. The telescopic rod 8 will then retract to maintain the linear movement of the circular block 9 relative to the circular groove 7 (maintaining the linear extension and contraction of the high-elasticity spring 10 to prevent it from being damaged by oblique pulling), thereby keeping the high-elasticity spring 10 in place. When the water cleaning tank 1 is released from its fixed position with the side door 4, the high-elasticity spring 10 will use its rebound force to push the circular block 9 to move the side door 4 a certain distance away from the water cleaning tank 1 (the telescopic rod 8 will extend accordingly), so that it will no longer squeeze the spring switch 5. This avoids the operator forgetting to pull the side door 4 (only releasing the fixed position between the side door 4 and the water cleaning tank 1), which would cause the device to continue to operate and waste resources (the elastic force of the spring inside the spring switch 5 is not enough to push the side door 4 which has a certain weight. Without the assistance of the above components, the spring switch 5 may still be in the squeezed open state if the operator does not pull the side door 4).

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
