[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention. Example 1

[0043] Reference Figures 1-8 A splash-free, self-closing bed shampooing device includes an L-shaped base plate 1 and a water tank 2 fixedly connected to the L-shaped base plate 1. A shampoo basin 3 is slidably connected above the water tank 2, and the shampoo basin 3 has an arc groove 301. It also includes a headrest 4 disposed within the shampoo basin 3 and a hollow rod 401 fixedly connected to the bottom of the headrest 4. The headrest 4 has fine holes 404, and a control component is disposed within the hollow rod 401. When the hollow rod 401 moves downward within the shampoo basin 3, the water flow within the shampoo basin 3 can... The water can be discharged into the water tank 2. A sealing cylinder 202 is fixedly connected inside the water tank 2, and a horizontal plate 201 is fixedly connected to the outer wall of the sealing cylinder 202. A partition 203 is provided between the horizontal plate 201 and the top inner wall of the water tank 2. An inclined plate 7 is fixedly connected to the L-shaped bottom plate 1. A spray head 8 is provided inside the inclined plate 7. An auxiliary plate 9 is provided on the side wall of the shampoo basin 3. The bottom of the hollow rod 401 is placed inside the water tank 2, and the hollow rod 401 is located above the horizontal plate 201. A through hole 405 is provided at the bottom of the hollow rod 401.

[0044] In this invention, during use, the device is pushed to the bedside, and the user's head is placed on the headrest 4 inside the shampoo basin 3. Simultaneously, the user's neck is placed within the arc groove 301, providing neck support. An auxiliary plate 9 is also provided to support the user's back, making it easier to use. Then, the user washes their hair using the spray nozzle 8 inside the inclined plate 7. The spray nozzle 8 is interlocked with the inclined plate 7, allowing it to be removed for handheld use or placed directly on the inclined plate 7 for automatic spraying. When the patient presses their head down on the headrest 4, it activates the control components, allowing the water sprayed into the shampoo basin 3 to flow through... The water flows down through the through hole 405 on the hollow rod 401 and enters the water tank 2. A horizontal plate 201 is provided in the water tank 2. The used water will fall to the top of the horizontal plate 201, and the unused water will be injected below the horizontal plate 201 for easy differentiation. After washing the hair, the water above the horizontal plate 201 can be discharged for other uses. The water tank 2 is also equipped with a water inlet pipe, which can easily inject warm water suitable for washing hair into the water tank 2. The water tank 2 is also equipped with a drain pipe, which can drain the unused water in the water tank 2 to avoid waste and at the same time speed up the washing time, avoiding the patient from catching a cold due to prolonged washing.

[0045] It should be noted that the L-shaped base plate 1 in this application can be set to a smaller size, so that the L-shaped base plate 1 can be placed on the bed for use, making it more convenient to use. Example 2

[0046] Reference Figures 1-8 A splash-free, self-closing bed shampooing device includes an L-shaped base plate 1 and a water tank 2 fixedly connected to the L-shaped base plate 1. A shampoo basin 3 is slidably connected above the water tank 2, and the shampoo basin 3 has an arc groove 301. It also includes a headrest 4 disposed within the shampoo basin 3 and a hollow rod 401 fixedly connected to the bottom of the headrest 4. The headrest 4 has fine holes 404, and a control component is disposed within the hollow rod 401. When the hollow rod 401 moves downward within the shampoo basin 3, the water flow within the shampoo basin 3 can... The water can be discharged into the water tank 2. A sealing cylinder 202 is fixedly connected inside the water tank 2, and a horizontal plate 201 is fixedly connected to the outer wall of the sealing cylinder 202. A partition 203 is provided between the horizontal plate 201 and the top inner wall of the water tank 2. An inclined plate 7 is fixedly connected to the L-shaped bottom plate 1. A spray head 8 is provided inside the inclined plate 7. An auxiliary plate 9 is provided on the side wall of the shampoo basin 3. The bottom of the hollow rod 401 is placed inside the water tank 2, and the hollow rod 401 is located above the horizontal plate 201. A through hole 405 is provided at the bottom of the hollow rod 401.

[0047] Reference Figure 3 , Figure 4 and Figure 8The control assembly includes an annular cylinder 505 fixedly connected to the inner wall of the shampoo basin 3, and an annular groove 506 at the bottom of the annular cylinder 505. The annular cylinder 505 also has a small hole 507 communicating with the annular groove 506. A hollow rod 401 is slidably connected inside the annular cylinder 505. A conical hole 403 is provided on the hollow rod 401. A sliding rod 501 is slidably connected inside the conical hole 403. One end of the sliding rod 501 has a semi-circular block 502 that abuts against the inner wall of the annular cylinder 505, and the other end of the sliding rod 501 has a sealing ball block 5 that abuts against the inner wall of the conical hole 403.

[0048] Reference Figure 3 , Figure 4 and Figure 8 A ring plate 406 is fixedly connected to the outer wall of the hollow rod 401. A first spring 407 is provided between the ring plate 406 and the bottom of the shampoo basin 3. The first spring 407 is sleeved on the hollow rod 401. A limit block 503 is fixedly connected to the inner wall of the conical hole 403. A second spring 504 is connected between the limit block 503 and the semi-circular block 502. The second spring 504 is sleeved on the slide rod 501.

[0049] In this invention, when the user's head is placed on the headrest 4 and the headrest 4 is moved downwards, the hollow rod 401 will move. In the initial state, that is, when the hollow rod 401 has not moved downwards, the sealing ball 5 abuts against the inner wall of the conical hole 403, and the sealing ball 5 is provided with a rubber pad, which can enhance the sealing between it and the conical hole 403. At this time, since the conical hole 403 is blocked, water will not flow through. When the hollow rod 401 moves downwards, it will drive the semicircular block 502 to slide downwards on the inner wall of the annular cylinder 505. At this time, the second spring 504 is in a compressed state, which can make the semicircular block 502 slide downwards against the annular cylinder 505. When the inner wall of the 05 is abutted, after the semicircular block 502 moves to be flush with the annular groove 506, the elastic force of the second spring 504 will cause the semicircular block 502 to return to its original position, so that the semicircular block 502 abuts against the inner wall of the annular groove 506. At this time, the semicircular block 502 will drive the sealing ball block 5 to move through the sliding rod 501, so that it no longer abuts against the conical hole 403. At this time, the water will enter the conical hole 403 through the gap between the hollow rod 401 and the annular cylinder 505, and then enter the hollow rod 401 and fall down. Then, it will flow out through the through hole 405 at the bottom of the hollow rod 401 to the top of the horizontal plate 201, so as to avoid water splashing and wetting the sheets or the ground.

[0050] Reference Figure 3 and Figure 5A square tube 6 is fixedly connected between the horizontal plate 201 and the bottom inner wall of the water tank 2. A piston block 601 is slidably connected inside the square tube 6. A push rod 402 is fixedly connected to the bottom of the hollow rod 401. A sealing groove 602 is provided inside the piston block 601. The bottom of the push rod 402 is placed in the sealing groove 602 and connected to a sealing plate 408. An air outlet 607 is provided on the top of the square tube 6 and the horizontal plate 201. An air inlet pipe 603, a first air outlet pipe 604 and a second air outlet pipe 605 are provided on the bottom of the square tube 6 and the L-shaped base plate 1. The first air outlet pipe 604 is connected to the sealing groove 602, and the end of the first air outlet pipe 604 placed inside the square tube 6 is a telescopic pipe.

[0051] In this invention, when the hollow rod 401 moves downward, it drives the push rod 402 to move, which causes the sealing plate 408 at the bottom of the push rod 402 to move within the sealing groove 602, conveying the gas in the sealing groove 602 to the first outlet pipe 604. When the sealing plate 408 moves to the bottom of the sealing groove 602, if the hollow rod 401 continues to drive the sealing plate 408 downward, the piston block 601 will slide within the square tube 6, conveying the gas within the square tube 6 to the second outlet pipe 605. Furthermore, a one-way valve is provided on the inlet pipe 603, preventing gas from being discharged through the inlet pipe 603 when the piston block 601 moves downward. The end of the first outlet pipe 604 located within the square tube 6 is a telescopic tube, which compresses when the piston block 601 moves downward, without affecting normal use.

[0052] After the shampoo is finished, the hollow rod 401, driven by the first spring 407, automatically resets the headrest 4, making it convenient for the next use. At this time, the control component is closed, and the water in the shampoo basin 3 will no longer flow out. It should be noted that there is an inclined surface on the annular groove 506. The tension line of the first spring 407 will cause the semicircular block 502 to pass through the inclined surface and abut against the inner wall of the annular cylinder 505 again, so that the sealing ball 5 abuts against the conical hole 403 again, thus sealing again. The first spring 407 is larger than the second spring 504. Under the tension of the first spring 407, the semicircular block 502 can reset better, while the second spring 504 is compressed again. When the hollow rod 401 resets, it will drive the push rod 402 and the sealing plate 408 to move upward. When the sealing plate 408 moves to the top of the sealing groove 602, it will drive the piston block 601 to move upward, realizing the complete reset. Example 3

[0053] Reference Figure 3 , Figure 5 and Figure 6A splash-free, self-closing bed shampooing device includes an L-shaped base plate 1 and a water tank 2 fixedly connected to the L-shaped base plate 1. A shampoo basin 3 is slidably connected above the water tank 2, and the shampoo basin 3 has an arc groove 301. It also includes a headrest 4 disposed within the shampoo basin 3 and a hollow rod 401 fixedly connected to the bottom of the headrest 4. The headrest 4 has fine holes 404, and a control component is disposed within the hollow rod 401. When the hollow rod 401 moves downward within the shampoo basin 3, the water flow within the shampoo basin 3 can... The water can be discharged into the water tank 2. A sealing cylinder 202 is fixedly connected inside the water tank 2, and a horizontal plate 201 is fixedly connected to the outer wall of the sealing cylinder 202. A partition 203 is provided between the horizontal plate 201 and the top inner wall of the water tank 2. An inclined plate 7 is fixedly connected to the L-shaped bottom plate 1. A spray head 8 is provided inside the inclined plate 7. An auxiliary plate 9 is provided on the side wall of the shampoo basin 3. The bottom of the hollow rod 401 is placed inside the water tank 2, and the hollow rod 401 is located above the horizontal plate 201. A through hole 405 is provided at the bottom of the hollow rod 401.

[0054] Reference Figure 3 , Figure 5 and Figure 6 The inclined plate 7 is provided with a groove 701 and a circular groove 702. The L-shaped base plate 1 is provided with a connecting pipe 606 that is connected to the first air outlet pipe 604 and the second air outlet pipe 605. The connecting pipe 606 is connected to the circular groove 702. A baffle 703 is slidably connected in the groove 701. A connecting plate 704 is fixedly connected to the baffle 703. A connecting rod 705 is provided on the connecting plate 704. A circular block 706 is provided on the connecting rod 705. The circular block 706 is slidably connected in the circular groove 702.

[0055] Reference Figure 6 An annular block 708 is provided in the circular groove 702. An elastic element 707 is provided between the annular block 708 and the circular block 706. The nozzle 8 is snapped into the groove 701 and is provided with a water inlet pipe 801. A water pump 805 is provided on the water tank 2. The water pump 805 is provided with a water suction pipe 804 at the water suction end. The water suction pipe 804 is connected to the bottom of the water tank 2. The water inlet pipe 801 is connected to the water outlet end of the water pump 805.

[0056] In this invention, the gas discharged from the first air outlet pipe 604 and the second air outlet pipe 605 enters the connecting pipe 606, and then enters the circular groove 702, pushing the circular block 706 to move. This causes the circular block 706 to move the connecting rod 705, and then the connecting plate 704 moves the baffle 703, so that the baffle 703 no longer blocks the nozzle 8. At this time, the shampooing operation can be performed through the nozzle 8. After the shampooing is completed, the hollow rod 401 and the head support 4 automatically reset. The elastic element 707 enables the circular block 706 to automatically reset, thereby resetting the baffle 703 and preventing dust and other particles from entering the groove 701 and affecting the use of the nozzle 8.

[0057] It should be noted that the nozzle 8 and the inner wall of the groove 701 are interlocked, making it easy to remove and use, easy to install after use, and versatile in use.

[0058] Reference Figure 3 and Figure 6 The L-shaped base plate 1 is rotatably connected to a rotating shaft 802, and a spiral spring 803 is provided on the rotating shaft 802. The water inlet pipe 801 is sleeved on the spiral spring 803.

[0059] In this invention, the water pump 805 is started, and water is drawn into the water tank 2 through the water pipe 804. The water is then discharged to the nozzle 8 through the water inlet pipe 801, and sprayed out from the nozzle 8 for use. When the nozzle 8 is removed, pulling the nozzle 8 or the water inlet pipe 801 can pull out the water inlet pipe 801 for use, making it convenient for personnel to hold the nozzle 8 to wash the user's hair. When the water inlet pipe 801 is pressed, the spiral spring 803 is compressed. After the nozzle 8 is placed into the groove 701, the water inlet pipe 801 will reset under the action of the spiral spring 803 and retract into the L-shaped base plate 1, thus hiding the water inlet pipe 801. This saves space and prevents the water inlet pipe 801 from being exposed for a long time, thereby increasing its service life. Example 4

[0060] Reference Figures 1-5 and Figure 7 A splash-free self-draining bed shampooing device is basically the same as in Embodiment 1, but further, the bottom of the shampoo basin 3 is fixedly connected with a threaded rod 302 and multiple guide posts 308, the bottom inner wall of the water tank 2 is rotatably connected with a threaded cylinder 303, the bottom of the threaded rod 302 is threadedly connected to the threaded cylinder 303, and the outer wall of the threaded cylinder 303 is provided with a first gear 304. The inner wall of the water tank 2 is provided with an output motor 305, the output end of the output motor 305 is provided with an output shaft 306, and the output shaft 306 is provided with a second gear 307 that meshes with the first gear 304. The bottom of the water tank 2 is also provided with a sleeve 309, and the guide posts 308 are slidably connected in the sleeve 309. The threaded cylinder 303, the output motor 305 and the sleeve 309 are all set in the sealing cylinder 202.

[0061] In this invention, the output motor 305 is started, thereby driving the output shaft 306 to rotate. This causes the second gear 307 to rotate and mesh with the first gear 304, causing the first gear 304 to rotate. This, in turn, drives the threaded cylinder 303 to rotate, making it threadedly connected to the threaded rod 302. At this time, the limiting effect of the guide post 308 and the sleeve 309 is small, causing the threaded rod 302 to move upward, thereby driving the shampoo basin 3 to move upward. At the same time, the guide post 308 slides within the sleeve 309, making the movement more stable and preventing the threaded rod 302 from rotating along with the threaded cylinder 303. The output motor 305 is a motor capable of forward and reverse rotation. When the output motor 305 rotates forward, it can drive the shampoo basin 3 to rise. When the output motor 305 rotates in reverse, it can drive the shampoo basin 3 to fall, making it easy to adjust the height of the shampoo basin 3. The sealing cylinder 202 can protect the output motor 305 and other components, preventing water from entering and damaging the motor. Example 5
