Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, specifically to a U-shaped tube device for preventing toilet splashing. Background Technology

[0002] In daily life, when using the toilet, the problem of water splashing when excrement falls into the toilet's water seal is common. This splashing water not only causes discomfort to the user but can also contaminate the surrounding environment, breed bacteria, and affect hygiene.

[0003] Currently, while some toilet splash-proof solutions exist on the market, most have significant shortcomings. For example, some products cover the toilet water seal surface with a layer of splash-proof foam or film. While this method can reduce splashing to some extent, it requires users to add additional splash-proof materials, which is cumbersome and expensive, increasing the financial burden in the long run. Additionally, some toilet splash-proof devices achieve splash prevention by altering the structure of the toilet water seal. However, this often requires large-scale modifications to the toilet, resulting in complex installation, high costs, and potential impact on the toilet's functionality and appearance.

[0004] Existing toilet splash-proof technologies suffer from a common problem: their splash-proof effect is not stable or timely enough. Some devices cannot automatically adjust their splash-proof measures according to the toilet's usage status; for example, they may not activate the splash-proof function in time when the toilet seat is lifted, resulting in the inability to effectively prevent water splashing in actual use.

[0005] In summary, existing toilet splash-proof technologies suffer from drawbacks such as cumbersome operation, high cost, complex installation, and unstable and untimely splash-proof effects, failing to meet people's actual needs for toilet splash-proof functionality. Therefore, developing a toilet splash-proof device that is easy to operate, low in cost, convenient to install, and provides stable and timely splash-proof effects is of significant practical importance. Utility Model Content

[0006] The purpose of this utility model is to provide a U-shaped tube device for toilet splash prevention, so as to solve the problems of cumbersome operation, high cost, complicated installation, unstable and untimely splash prevention effect in the existing toilet splash prevention technology, and realize the automation and efficiency of toilet splash prevention function.

[0008] Preferably, the fixing bracket is welded to one side of the bearing seat, and a set screw is rotatably connected to the fixing bracket. The set screw abuts against the side edge of the toilet to limit and fix the bearing seat.

[0009] Preferably, a wheel frame is provided at the front of the bearing housing, and a fixed pulley is rotatably mounted on the wheel frame.

[0010] Preferably, the pull rope is wound around and connected to the fixed pulley, one end of the pull rope is fixed to the bottom of the support rod, and the other end is provided with a rope loop, through which the pull rope is connected to the toilet seat.

[0011] Preferably, the top of the support rod is provided with a mounting surface, the connector is provided with a threaded hole and fixed on the mounting surface, and the end of the U-shaped tube is provided with a through hole. The specification of the through hole is adapted to the threaded hole, and the screw matching the threaded hole passes through and is assembled into the threaded hole to realize the sleeve fixation of the U-shaped tube and the support rod.

[0012] Preferably, a photosensitive sensor is also installed at the bottom of the toilet seat, and the photosensitive sensor is connected to a compressed air pump via a signal line.

[0013] Compared with the prior art, the advantages of this utility model are: (1) Simple operation: This device does not require users to add extra anti-splash materials.

[0020] Example

[0021] like Figures 1 to 4 As shown, this embodiment provides a U-shaped tube device for toilet splash prevention. The support rod 1 has a long, hollow rod structure with a mounting surface 101 at the top. The mounting surface 101 is a flat surface with a certain area for fixing the connector 11. The support rod 1 serves as the main supporting component of the entire device, connecting and supporting other parts. Its own lifting movement drives the U-shaped tube 3 to rise and fall, thereby activating and deactivating the splash prevention function. A bearing seat 2 is slidably mounted on the support rod 1, allowing it to slide up and down within the bearing seat 2. One end of a pull rope 4 is fixed to the bottom of the support rod 1. The top mounting surface 101 of the support rod 1 is fixedly connected to one side of the connector 11 by screws. The bottom of the support rod 1 is connected to a compressed air pump 6 via a hose 5.

[0022] The bearing housing 2 has an internal channel through which the support rod 1 slides. A fixing bracket 9 is welded to the side, and a wheel frame 7 is provided at the front. The bearing housing 2 provides support and guidance for the sliding of the support rod 1, and is also connected and fixed to the toilet 12 through the fixing bracket 9. The bearing housing 2 is connected to the outer side of the upper edge of the toilet 12 through the fixing bracket 9 on the side; a fixed pulley 8 is rotatably mounted on the wheel frame 7 at the front; the support rod 1 is slidably mounted in the internal channel of the bearing housing 2.

[0023] The bottom of the U-shaped tube 3 has multiple air outlets 301, which are small perforated structures for gas ejection. Under the action of the compressed air pump 6, the gas is ejected from the air outlets 301 to form an air wall, which serves to prevent splashing. The end tube of the U-shaped tube 3 is connected to the support rod 1 via a connector 11. One side of the connector 11 is fixed to the mounting surface 101 on the top of the support rod 1 with screws, and the other side is fixed to the end tube of the U-shaped tube 3 with screws. The support rod 1 is internally connected to the U-shaped tube 3, and the bottom of the support rod 1 is also connected to the air outlet of the compressed air pump 6. When the compressed air pump 6 operates, it transmits compressed air to the U-shaped tube 3 via the support rod 1.

[0024] The pull cord 4 is a rope of a certain strength, with a rope loop 401 at one end. Connected to the toilet seat 1201 and the support rod 1, it pulls the support rod 1 upwards when the toilet seat 1201 is lifted, thus activating the splash-proof function. The pull cord 4 is wound around the fixed pulley 8, with one end fixed to the bottom of the support rod 1, and the other end connected to the toilet seat 1201 via the rope loop 401.

[0025] The air pump port of the compressed air pump 6 is connected to the bottom of the support rod 1 through the hose 5; at the same time, the compressed air pump 6 is connected to the photosensitive sensor through the signal line, and receives the signal from the photosensitive sensor to control the working status.

[0026] The pulley frame 7 provides a mounting position for the fixed pulley 8, ensuring its stable rotation. The pulley frame 7 is fixed to the front of the bearing seat 2, and the fixed pulley 8 is rotatably mounted on the pulley frame 7. The fixed pulley 8 changes the transmission direction of the pull rope 4, enabling the pull rope 4 to smoothly pull the support rod 1 upward.

[0027] The fixing frame 9 is a frame structure welded to one side of the bearing seat 2. A set screw 10 is rotatably connected to it. By rotating the set screw 10, it abuts against the upper edge of the toilet 12, thereby limiting and fixing the bearing seat 2 and preventing the bearing seat 2 from shifting during use.

[0028] The connector 11 has a screw hole on one side for connecting the support rod 1 and the U-shaped tube 3, so that the two can be reliably connected together and achieve synchronous movement. One side of the connector 11 is fixed to the mounting surface 101 on the top of the support rod 1, and the other side is fixed to the U-shaped tube 3 by screws.

[0029] In addition, the pull cord 4 is connected to the toilet seat 1201 through the cord loop 401. The bottom of the toilet seat 1201 is also equipped with a photosensitive sensor, which is connected to the compressed air pump 6 through a signal line.

[0030] Based on the above structural features, the overall working process of this toilet splash-proof U-shaped tube device is as follows: I. Initial State With the toilet seat 1201 in the lowered position, the pull cord 4 is slack, and the support rod 1 is in a relatively low position due to its own weight. The U-shaped tube 3 is also in a low position, and no gas is being ejected from it. The photosensitive sensor is continuously monitoring, sensing changes in light levels at the bottom of the toilet seat 1201 in real time. The compressed air pump 6 is in standby mode, waiting to receive a start signal.

[0031] II. Splash prevention function activated during male urination. The toilet seat 1201 is lifted up. Since one end of the pull cord 4 is connected to the toilet seat 1201 via a loop 401, and the other end is fixed to the bottom of the support rod 1, and the pull cord 4 is wound around a fixed pulley 8, the lifting action of the toilet seat 1201 pulls the pull cord 4. Under the action of the fixed pulley 8, the pull cord 4 changes its transmission direction, transmitting an upward pulling force to the support rod 1. Under the action of the pulling force, the support rod 1 overcomes its own weight and slides upward within the internal channel of the bearing seat 2. The bearing seat 2 is fixed to the outer side of the upper edge of the toilet 12 via a fixing bracket 9 and a set screw 10, providing stable support and guidance for the sliding of the support rod 1, ensuring that the support rod 1 can rise smoothly.

[0032] As the support rod 1 rises, the U-shaped tube 3, integrally connected to the support rod 1 via the connector 11, is also lifted. The U-shaped tube 3 rises from its lower position to a suitable position, at which point the multiple air outlets 301 at the bottom of the U-shaped tube 3 are exposed above the toilet water seal. Simultaneously, a photosensitive sensor mounted on the bottom of the toilet seat 1201 detects the change in light intensity at the bottom of the toilet seat 1201 after it is lifted (e.g., from a dark environment with obstructions to a bright environment without obstructions). The photosensitive sensor converts this brightness change into an electrical signal and transmits it to the compressed air pump 6 via a signal line. Upon receiving the signal, the compressed air pump 6 immediately starts operating, beginning to deliver compressed air into the U-shaped tube 3. The compressed air is delivered from the air outlet of the compressed air pump 6 through the hose 5 to the bottom opening of the support rod 1, and then enters the U-shaped tube 3 through the top opening of the support rod 1. The compressed air entering the U-shaped tube 3 is ejected at high speed from the multiple air outlets 301 at the bottom, forming a wall of air. This air barrier effectively prevents splashing water when men urinate, avoiding the mixing of splashed water and urine to contaminate the area around the toilet and cause discomfort to the user.

[0033] III. Completion of Use After urinating, the man lowers the toilet seat 1201. During this lowering process, the pull cord 4 is no longer under upward tension, and the support rod 1 begins to descend under its own weight. The support rod 1 slides downward within the internal channel of the bearing seat 2, driving the U-shaped tube 3 downward via the connector 11, returning the U-shaped tube 3 to its initial low position. Simultaneously, after the toilet seat 1201 is lowered, the photosensitive sensor detects a change in the brightness of the light at the bottom of the toilet seat 1201 (from a bright environment to a dark environment). The photosensitive sensor transmits this signal to the compressed air pump 6 via a signal line. Upon receiving the signal, the compressed air pump 6 stops operating, ceasing to supply compressed air into the U-shaped tube 3. Gas ejection from the U-shaped tube 3 stops, and the splash-proof function is deactivated.

[0034] In summary, this device, through the lifting and lowering action of the toilet seat 1201, combined with the coordinated operation of components such as the pull cord 4, support rod 1, bearing seat 2, U-shaped tube 3, photosensitive sensor, and compressed air pump 6, achieves automated and efficient anti-splash function during male urination. The entire workflow is logically clear, and the various components work closely together, providing users with a more hygienic and comfortable experience.

[0035] In addition, the specific shape of the U-shaped tube can be customized according to actual needs, and is not limited to a U-shape. The fixed pulley is not limited to being fixed to the bearing housing; it can also be fixed to the rim of the toilet. The compressed air pump can be fitted with a pump body for other media as needed.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
