Description

Technical Field

[0001] This utility model relates to the field of waterproof dishwasher lenses, and in particular to a waterproof dishwasher lens. Background Technology

[0002] As dishwashers become more and more popular, the demand for them is also increasing, leading to a greater need for digital projection displays on dishwashers. The waterproof lens installed on the dishwasher is mainly for users to conveniently view the dishwasher's working status in real time, facilitating human-computer interaction.

[0003] The existing dishwasher lens consists of an imaging lens housing, a protective shell, a segment display, and a condenser lens. The observed interior scene of the dishwasher is projected onto the segment display through the condenser lens by a light source, and then the image on the segment display is projected to the outside through the imaging lens housing, facilitating human-computer interaction.

[0004] Current dishwasher lens devices project changing images through a segmented screen, but these devices lack a waterproof structure, making it easy for moisture to enter and affect the image quality. Therefore, a waterproof dishwasher lens is proposed to solve this problem. Utility Model Content

[0032] 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.

[0033] Reference Figures 1-5 This utility model provides an embodiment of a waterproof dishwasher lens, including a housing 1. The housing 1 serves as a supporting structure, protecting internal components from damage and preventing external moisture from entering. An imaging lens housing 8 is fixedly connected to the left side of the housing 1, projecting the internal image onto the outside of the device for easy human-computer interaction. A lens barrel 2 is fixedly connected to the bottom of the housing 1. The lens barrel 2 is located inside the dishwasher and is one of the main structures for observing the inside of the dishwasher. A fixing ring 3 is fixedly connected to the bottom of the lens barrel 2, and a connecting tube 4 is threadedly connected to the bottom side of the inside of the lens barrel 2. The outer periphery is connected to a positioning tube 5. The bottom of the connecting tube 4 is slidably connected to a protective shell 6. The lens 7 is slidably connected inside the protective shell 6. The connecting tube 4 is used to connect the lens barrel 2 and the protective shell 6. The positioning tube 5 fixes the protective shell 6 to the connecting tube 4. The top inner side of the protective shell 6 is slidably connected to a sealing ring 20. The inner side of the protective shell 6 is slidably connected to a positioning frame 21. The positioning frame 21 is movably connected to the bottom of the connecting tube 4. The positioning frame 21 and the sealing ring 20 clamp the lens 7 in the middle to fix the lens 7. At the same time, the sealing ring 20 is connected between the lens 7 and the protective shell 6 to play a waterproof role. The outer shell 1 is equipped with a positioning component.

[0034] Reference Figures 1-3 The positioning component includes a fixing frame 9, which is fixedly connected inside the housing 1. Positioning plates 10 are slidably connected to the left and right sides inside the fixing frame 9. Slide grooves 14 are opened on the left and right sides of the top of the fixing frame 9. The positioning plates 10 abut against the top inner side of the housing 1 and are slidably connected inside the slide grooves 14. A segment code screen 11 is slidably connected inside the fixing frame 9. A condenser lens 12 is slidably connected inside the fixing frame 9. The condenser lens 12 and the segment code screen 11 are modularly installed inside the housing 1 through the fixing frame 9, which reduces the space occupied by the modular installation.

[0035] Reference Figures 1-3 A sealing ring 13 is slidably connected to the outer periphery of the connecting tube 4. The sealing ring 13 abuts against the bottom of the fixing ring 3. The positioning tube 5 abuts against the bottom of the sealing ring 13. The sealing ring 13 is clamped between the fixing ring 3 and the positioning tube 5, which serves as a waterproof function. A through hole 15 is opened inside the fixing frame 9. The through hole 15 is the channel for image transmission. Multiple evenly distributed protrusions 16 are fixedly connected inside the protective shell 6. Multiple evenly distributed grooves 19 are opened on the outer periphery of the connecting tube 4. The protrusions 16 are slidably connected inside the grooves 19. Multiple evenly distributed fixing blocks 17 are fixedly connected to the top of the protective shell 6. Multiple evenly distributed fixing blocks 28 are fixedly connected to the bottom of the positioning tube 5. Both fixing blocks 17 and fixing blocks 28 are inverted L-shaped. The positioning tube 5 rotates to drive fixing blocks 28 to move and engage with fixing blocks 17 to fix the protective shell 6.

[0036] Working principle: The condenser lens 12 and segment code screen 11 are placed in the middle of the fixing frame 9, coaxial with the through hole 15 inside the fixing frame 9 and the imaging lens housing 8. Then, the positioning plate 10 is inserted into the top of the condenser lens 12 and segment code screen 11 inside the fixing frame 9. The top of the positioning plate 10 interacts with the outer shell 1, fixing the positioning plate 10 in the fixing frame 9. Then, the condenser lens 12 and segment code screen 11 are fixed in the fixing frame 9. The modular installation of components reduces the space occupied by the components. Then, the connecting tube 4 is rotated and installed to the bottom of the inner side of the lens barrel 2. The protective shell 6 slides inside the groove 19 through the protrusion 16. The protective shell 6 is installed on the outer periphery of the connecting tube 4. Then, the positioning tube 5 is rotated to drive the positioning... The fixing block 18 at the bottom of tube 5 rotates, and the fixing block 18 and fixing block 17 engage to restrict radial movement, thereby fixing the protective shell 6. During the fixing of the protective shell 6, the positioning frame 21 inside the protective shell 6 is squeezed by the connecting tube 4, which squeezes the lens 7, causing the lens 7 to squeeze the sealing ring 20. The sealing ring 20 is subjected to the action of the protective shell 6 and generates a reaction force, thereby fixing the lens 7 through the cooperation between the structures. At the same time, it squeezes the sealing ring 20 to enhance the waterproof effect. In addition, during the process of the connecting tube 4 rotating into the lens barrel 2, the positioning tube 5 and the sealing ring 13 are clamped by the connecting tube 4 and the fixing ring 3, which enhances the waterproof effect of the device.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
