Abstract
Description
Technical Field
[0001] This utility model relates to the field of washbasin technology, and in particular to a washbasin for a high-speed train. Background Technology
[0002] Inside modern high-speed trains, each carriage has a toilet, and each toilet has a washbasin for passengers to wash up.
[0003] On the existing high-speed rail washbasins, after prolonged use, dirt and water stains easily accumulate in the crevices of the surface. In addition, the washbasins are frequently exposed to washing water vapor, and the crevices are prone to a continuous damp state. In the enclosed and temperature-appropriate environment of the high-speed rail carriage, this can easily become a breeding ground for bacteria and mold, thereby affecting the hygiene and health of passengers. Utility Model Content
[0004] To address the issue of dirt and water stains easily accumulating in the gaps of the countertop, and the fact that the washbasin is frequently exposed to washing moisture, making the gaps prone to continuous dampness, which can easily become a breeding ground for bacteria and mold in the enclosed, temperature-controlled environment of a high-speed train carriage, thus affecting the hygiene and health of passengers, this utility model provides a washbasin for high-speed trains.
[0005] This utility model provides a washbasin for a high-speed train, adopting the following technical solution:
[0006] A washbasin for a high-speed train includes a support platform. A connecting plate is fixedly connected to the rear side of the support platform, and a mirror is fixedly connected to the front side of the connecting plate. Two movable slots are symmetrically opened on the front side of the connecting plate. A squeegee for cleaning the support platform is slidably connected inside each of the two movable slots. A storage slot is opened on the front side of the top of the support platform. A protective plate is slidably connected inside the storage slot. The front side of the squeegee abuts against the front side of the protective plate.
[0007] Optionally, in the washbasin of the above-mentioned high-speed train, the bottom of the squeegee is slidably engaged with the top of the support platform, the movable groove is L-shaped, a square plate is provided on the rear side of the bottom of the squeegee, the side of the square plate is fixedly connected to the interior of the vertical groove of the L-shaped movable groove, a sliding groove is provided on the bottom of the squeegee, and a movable plate is slidably connected inside the sliding groove.
[0008] The above technical solution facilitates the sliding of the squeegee along the L-shaped moving groove, enabling it to conform to the support table surface for horizontal squeegee cleaning, thus meeting the high-efficiency cleaning needs of the limited space in the washbasin area of a high-speed train.
[0009] Optionally, in the washbasin of the above-mentioned high-speed train, the movable plate is convex in shape, and a first compression spring is fixedly connected to the rear side of the movable plate. The rear end of the first compression spring is fixedly connected to the front side of the square plate.
[0010] The above technical solution allows the protective plate to move downwards into the storage groove by utilizing the elastic force of the first compression spring, and the wiper strip can then move forward to be on the same horizontal plane as the front side of the support platform.
[0011] Optionally, in the washbasin of the above-mentioned high-speed train, the bottom of the squeegee has a 45° bevel on both the left and right sides, and the bottom of the squeegee is coated with a rubber coating.
[0012] Through the above technical solution, the 45° bevel angle can reduce the contact resistance between the squeegee and water stains and dirt on the countertop when the squeegee moves, making the squeegee action less strenuous. At the same time, it guides the dirt to gather on both sides for centralized treatment. The rubber coating on the bottom can enhance the sealing between the squeegee and the countertop, improve the water absorption and cleaning effect, and the rubber material has good wear resistance and softness, which can not only avoid scratching the surface of the support table, but also adapt to the needs of long-term high-frequency use and extend the service life of the components.
[0013] Optionally, in the washbasin of the above-mentioned high-speed train, the shape of the protective plate and the shape of the inner wall of the storage slot are both T-shaped, and a second compression spring is fixedly connected to the bottom of the protective plate, and the bottom end of the second compression spring is fixedly connected to the bottom of the inner wall of the storage slot.
[0014] The above technical solution facilitates the precise matching of the protective plate and the storage slot through the T-shaped structure, preventing the protective plate from shifting or falling off during the lifting process, thus improving structural stability. The elastic support of the second compression spring allows the protective plate to spring upward to the protective position when not subjected to external force, forming a shield and protection on the front side of the support platform to prevent sewage from splashing out when the user washes their hands. When the squeegee needs to be used, simply press the protective plate to store it inside the storage slot. The operation is convenient and does not take up extra space, making it suitable for the use of the narrow space in high-speed trains.
[0015] Optionally, in the washbasin of the above-mentioned high-speed train, a C-shaped sealing strip is fixedly connected to the top of the protective plate, and a sealing groove that cooperates with the C-shaped sealing strip is opened on the upper side of the inner wall of the storage groove.
[0016] The above technical solution allows the C-shaped sealing strip to be precisely embedded in the sealing groove when the protective plate pops up to the closed position, forming a multi-layer sealing structure. This effectively prevents sewage and moisture generated during the use of the washbasin from seeping into the storage tank, preventing bacteria from growing in the storage tank, improving the hygiene of the washbasin and the service life of its components, and meeting the hygiene standards and maintenance requirements of high-speed trains.
[0017] Optionally, in the washbasin of the above-mentioned high-speed train, two placement frames are fixedly connected to both sides of the bottom of the support platform, and a retrieval slot is provided on the front side of the placement frame.
[0018] The above technical solution makes it easy to provide passengers with convenient space to store their personal belongings using the placement frame. It can be used to store small items such as toiletries and mobile phones, preventing items from falling or being lost due to random placement. The front retrieval slot design reduces the difficulty of taking and putting away items. Even if there is slight shaking during train operation, items can be easily stored and retrieved, improving the convenience and experience for passengers. At the same time, the symmetrical distribution structure makes the overall layout of the washbasin more balanced.
[0019] In summary, this utility model offers at least one of the following beneficial effects: After the protective plate is moved into the storage slot, the elastic force of the first compression spring pushes the squeegee forward, ensuring it is level with the front of the support platform and that the squeegee fully contacts the platform surface for squeegeeing. Simultaneously, the bottom of the squeegee presses against the protective plate and the top of the second compression spring, stably positioning the protective plate within the storage slot. This prevents wastewater from flowing into the storage slot when the squeegee is squeegeeing the top of the support platform, thereby reducing the possibility of bacterial growth in the gaps on the top surface of the support platform.
[0020] By simultaneously positioning the two squeegee strips on the rear side of the inner wall of the moving trough, the restriction on the protective plate is released. When the protective plate pops upward from the storage trough under the action of the second compression spring, the popped-out protective plate can effectively block the splashed sewage when the user washes their hands, preventing sewage from splashing onto the outside of the washbasin, keeping the environment of the train toilet clean and improving the user experience.

[0027] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.
[0028] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An embodiment of this utility model provides a washbasin for a high-speed train, including a support platform 1. A connecting plate 2 is fixedly connected to the rear side of the support platform 1, and a mirror 3 is fixedly connected to the front side of the connecting plate 2. Two movable grooves 4 are symmetrically opened on the front side of the connecting plate 2. A squeegee 5 for cleaning the support platform 1 is slidably connected inside the two movable grooves 4. A storage groove 6 is opened on the front side of the top of the support platform 1. A protective plate 7 is slidably connected inside the storage groove 6. The front side of the squeegee 5 abuts against the front side of the protective plate 7.
[0029] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The bottom of the squeegee 5 slides with the top of the support platform 1. The moving groove 4 is L-shaped. A square plate 8 is provided on the rear side of the bottom of the squeegee 5. The side of the square plate 8 is fixedly connected to the inside of the vertical groove of the L-shaped moving groove 4. A sliding groove 9 is provided on the bottom of the squeegee 5. A moving plate 10 is slidably connected inside the sliding groove 9. The squeegee 5 slides along the inside of the L-shaped moving groove 4, which can fit against the surface of the support platform 1 to perform horizontal squeegee cleaning, which meets the high-efficiency cleaning needs of the limited space of the high-speed train washbasin.
[0030] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The movable plate 10 is convex in shape. A first compression spring 11 is fixedly connected to the rear side of the movable plate 10. The rear end of the first compression spring 11 is fixedly connected to the front side of the square plate 8. Using the elastic force of the first compression spring 11, the protective plate 7 moves downward into the storage groove 6, and the wiper 5 can move forward to be on the same horizontal plane as the front side of the support platform 1.
[0031] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The bottom of the squeegee 5 has 45° bevels on both the left and right sides, and the bottom of the squeegee 5 is coated with a rubber coating. The 45° bevels reduce the contact resistance between the squeegee 5 and water stains and dirt on the countertop when it moves, making the squeegee action less strenuous. At the same time, it guides the dirt to the sides for centralized treatment. The rubber coating on the bottom enhances the seal between the squeegee 5 and the countertop, improving the water absorption and cleaning effect. In addition, the rubber material has good wear resistance and softness, which can not only avoid scratching the surface of the support table 1, but also adapt to the needs of long-term high-frequency use and extend the service life of the components.
[0032] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The protective plate 7 and the inner wall of the storage slot 6 are both T-shaped. The bottom of the protective plate 7 is fixedly connected to a second compression spring 12, and the bottom end of the second compression spring 12 is fixedly connected to the bottom of the inner wall of the storage slot 6. The T-shaped structure achieves a precise fit between the protective plate 7 and the storage slot 6, preventing the protective plate 7 from shifting or falling off during the lifting process, thus improving structural stability. The elastic support of the second compression spring 12 allows the protective plate 7 to spring upward to the protective position when not subjected to external force, forming a shield and protection on the front side of the support platform 1, preventing sewage from splashing out when the user washes their hands. When the squeegee 5 needs to be used, simply press the protective plate 7 to store it inside the storage slot 6. The operation is convenient and does not take up extra space, making it suitable for the use of the narrow space of the high-speed train.
[0033] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A C-shaped sealing strip 13 is fixedly connected to the top of the protective plate 7. A sealing groove 14 that matches the C-shaped sealing strip 13 is opened on the upper side of the inner wall of the storage groove 6. When the protective plate 7 is lifted to the closed position, the C-shaped sealing strip 13 can be accurately embedded in the sealing groove 14 to form a multi-seal structure, which effectively prevents sewage and water vapor generated during the use of the washbasin from seeping into the interior of the storage groove 6, prevents bacteria from growing in the storage groove 6, improves the hygiene of the washbasin and the service life of the components, and meets the hygiene standards and maintenance requirements of high-speed trains.
[0034] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The bottom of the support platform 1 has two fixedly connected placement frames 15 on both sides, and the front of the placement frames 15 has a retrieval slot 16. The placement frames 15 provide passengers with a convenient space to place their personal belongings, such as toiletries and mobile phones, to prevent items from falling or being lost due to random placement. The retrieval slot 16 on the front reduces the difficulty of taking and putting away items. Even if there is slight shaking during the train's movement, items can be easily stored and retrieved, improving the convenience and experience for passengers. At the same time, the symmetrical distribution structure makes the overall layout of the washbasin more balanced.
[0035] Working principle: When using the washbasin on this high-speed train, after the user presses the protective plate 7 and moves it into the storage slot 6, the first compression spring 11, which was originally in a compressed state, releases its elastic force, pushing the squeegee 5 forward. This ultimately brings the front end of the squeegee 5 to the same horizontal plane as the front edge of the support platform 1. This ensures that the bottom rubber coating of the squeegee 5 fully and tightly adheres to the surface of the support platform 1, and both squeegees 5 move inward simultaneously to scrape away water from the surface of the support platform 1. At the same time, the bottom of the squeegee 5 abuts against the top of the protective plate 7, stably compressing the protective plate 7 and the second compression spring 12 below it, firmly securing the protective plate 7 inside the storage slot 6. This effectively seals the opening of the storage slot 6, allowing the wastewater on the surface of the support platform 1 to be completely scraped into the washing pool at the top of the support platform 1 when the squeegee 5 is wiping, preventing it from flowing into the storage slot 6. This reduces the possibility of bacteria growth due to accumulated wastewater in the gaps on the top surface of the support platform 1, ensuring the health of passengers.
[0036] After cleaning, the user simply pushes both squeegee strips 5 backward simultaneously, retracting them to the rear position inside the moving groove 4. This releases the squeegee strips 5 from their restraint on the protective plate 7. At this point, the compressed second spring 12 quickly rebounds, pushing the protective plate 7 upward from the storage groove 6 and resetting it. The ejected protective plate 7 forms a stable barrier in front of the support platform 1, effectively preventing wastewater from splashing out during handwashing and preventing it from landing on the floor or walls outside the washbasin. This keeps the train restroom clean and dry, significantly improving passenger comfort and experience.
[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
