[0031] See Figures 1 to 5 As shown, in a first aspect, this utility model provides a flushing device with an exhaust structure, comprising: a water tank 1, a water pump 2, a jet pipe 3, a flushing chamber 4, and an exhaust pipe 5; the water tank 1 is connected to the water pump 2; the water inlet end of the jet pipe 3 is connected to the water pump 2; the water outlet end of the jet pipe 3 is connected to the lower end of the flushing chamber 4; the air inlet end of the exhaust pipe 5 is connected to the jet pipe 3 and is higher than the water surface 41 of the flushing chamber 4.

[0032] Specifically, the flushing device with an exhaust structure in this embodiment comprises at least a water tank 1, a water pump 2, a jet pipe 3, a flushing chamber 4, and an exhaust pipe 5. The water tank 1 provides water to the water pump 2, which pressurizes and pumps the water into the jet pipe 3. The outlet end of the jet pipe 3 is connected to the lower end of the flushing chamber 4 for flushing. The air inlet end of the exhaust pipe 5 is connected to the jet pipe 3 and is higher than the water surface 41 of the flushing chamber 4. Its design principle is that when the water pump 2 is working, the pumped water flows in the jet pipe 3 and forms a closed space with the water surface 41 of the flushing chamber 4. The two together compress the gas in the jet pipe 3. Since the air inlet end of the exhaust pipe 5 is higher than the water surface 41, the pressurized gas will be discharged through the exhaust pipe 5.

[0033] When the flushing operation is initiated, water pump 2 starts working, and water in water tank 1 is pumped into spray pipe 3. As the water flows forward in the pipe, the space for gas movement within spray pipe 3 is continuously compressed due to the obstruction of the water cover 41 in flushing chamber 4. Under the dual compression of the water cover 41 and the water flow pumped out by water pump 2, the gas pressure gradually increases, eventually entering the exhaust pipe 5 through the air inlet end of the exhaust pipe 5, which is higher than the water cover 41, and then being discharged from the device, ensuring smooth water flow within spray pipe 3.

[0034] This design effectively solves the problem of gas accumulation in the jet pipe 3. Through the coordinated squeezing action of the water cover 41 and the water pump 2, the gas is discharged in time, significantly reducing flushing noise. At the same time, it ensures the stability and impact force of the water output, enabling the water flow to efficiently flush the flushing chamber 4 in a stable state, thus improving the flushing effect of the flushing device.

[0035] In one specific embodiment, the water pump 2 is connected to an output pipe 21, and the spray pipe 3 includes a spray inlet pipe 31 and a spray outlet pipe 32. The output pipe 21, the spray inlet pipe 31 and the spray outlet pipe 32 are connected in sequence in a Π shape. The bottom end of the spray outlet pipe 32 is the water outlet end of the spray pipe 3, and the air inlet end of the exhaust pipe 5 is connected to the spray outlet pipe 32.

[0036] Specifically, the Π-shaped structure formed by the sequential connection of the output pipe 21, the jet inlet pipe 31, and the jet outlet pipe 32 rationally plans the water flow path. After the water pump 2 sends water into the jet pipe 3, the water flows in the Π-shaped pipe, forming a compression environment for the gas in conjunction with the water cover 41 of the flushing chamber 4. Since the exhaust pipe 5 is connected to the jet outlet pipe 32, the pressurized gas can be discharged through this connection point.

[0037] After water pump 2 starts, water enters from output pipe 21 and flows sequentially through jet inlet pipe 31 and jet outlet pipe 32. During the water flow, the water cover 41 of flushing chamber 4 prevents gas from flowing towards flushing chamber 4. Water pumped by water pump 2 continuously enters the pipeline, causing the gas in jet pipeline 3 to be continuously compressed. As the degree of compression increases, the gas is eventually discharged through vent pipe 5 connected to jet outlet pipe 32, ensuring the smooth flow of water in jet pipeline 3.

[0038] By optimizing the structure of the jet pipe 3 and rationally connecting the exhaust pipe 5, the squeezing effect of the water cover 41 and the water pump 2 on the gas is further enhanced, and the gas discharge path is optimized. Compared with ordinary flushing devices, this design can discharge gas more quickly and effectively, greatly ensuring the stability of the water output, reducing water flow fluctuations caused by gas, reducing flushing noise, and improving the overall performance of the flushing device.

[0039] In one specific embodiment, the flushing chamber 4 is also connected to a water trap channel 6, and a top bend 61 is provided in the middle of the water trap channel 6, with the water cover 41 formed at the lowest point of the top bend 61.

[0040] Specifically, by setting the top bend 61, a stable water surface 41 can be formed at the top bend 61 of the water trap channel 6. This prevents sewer odors from rising to the surface and, during flushing, works together with the water pumped into the spray pipe 3 by the water pump 2 to compress the gas in the spray pipe 3. The air inlet of the exhaust pipe 5 is higher than the water surface 41, providing a channel for the pressurized gas to escape.

[0041] During flushing, water pump 2 pumps water from water tank 1 into spray pipe 3, while water in flushing chamber 4 is discharged through water trap channel 6, maintaining a constant water level at the top bend 61 to form a water cover 41. As water pump 2 continuously pumps water, the water cover 41 blocks gas, causing the gas in spray pipe 3 to be compressed and its pressure to gradually increase. Because the air inlet of exhaust pipe 5 is higher than the water cover 41, the gas smoothly enters exhaust pipe 5 and is discharged from the device, achieving effective gas discharge and odor blocking during flushing.

[0042] This design, while ensuring proper venting, cleverly utilizes the water cover 41 to prevent sewer odors from rising and improves air quality in the bathroom. The stable water cover 41, working in conjunction with the water pump 2, ensures effective compression and smooth discharge of gas, enabling the flushing device to efficiently vent air while creating a comfortable and hygienic environment for the user.

[0043] Preferably, the trap channel 6 is a drain pipe, which can directly utilize the mature structure and installation standards of drain pipes, reducing the design and manufacturing costs of the device. The drain pipe itself has a stable water seal capability, which can reliably prevent sewer odors from rising and ensure the hygiene of the bathroom environment. Its pipe diameter and slope are optimized to ensure that flushing wastewater is discharged quickly and to stably form a water cover 41 at the top bend 61, which, in conjunction with the vent pipe 5, effectively compresses the gas in the jet pipe 3. In addition, the use of a universal drain pipe facilitates standardized production and replacement of parts, improves installation efficiency, enhances device compatibility, is suitable for various toilet models, simplifies research and development and maintenance processes, and combines practicality and economy.

[0044] In one specific embodiment, the air inlet of the exhaust pipe 5 is lower than the highest water level 11 of the water tank 1.

[0045] Specifically, this design principle is based on spatial layout considerations. The air inlet of the exhaust pipe 5 is lower than the highest water level 11 of the water tank 1. While meeting the venting function, lowering the position of the air inlet of the exhaust pipe 5 optimizes the spatial layout of the overall flushing device, making component installation more flexible and adaptable to bathroom equipment with different structures. In addition, the lower air inlet position can expel as much gas as possible from inside the pipe, improving venting efficiency and ensuring stable operation of the flushing device.

[0046] When the flushing device is activated, water pump 2 pumps water from water tank 1 into spray pipe 3. The water surface 41 of the flushing chamber 4, together with the water flow, compresses the gas, which is then discharged through exhaust pipe 5. Because the air inlet of exhaust pipe 5 is lower than the maximum water level 11 of water tank 1, the gas can be discharged for a relatively long time during the gas discharge process. After the gas is discharged, the water flow will submerge the air inlet of exhaust pipe 5, and a certain amount of water will flow out from the exhaust pipe, thereby preventing backflow of air and allowing the water to flow rapidly in a closed environment to stably flush the flushing chamber 4.

[0047] This design effectively prevents air backflow and ensures a stable exhaust process, thereby guaranteeing a stable flushing flow, reducing noise, and improving flushing performance. Furthermore, it reduces component energy consumption and cost, simplifies the structure, improves production efficiency, and enhances product market competitiveness.

[0048] It is understood that the formation of the highest water level line 11 in water tank 1 is a conventional technical means commonly known and employed by those skilled in the art. This includes, but is not limited to, automatically controlling the inflow of water by configuring a level sensor and linking it with a control valve, setting an overflow port, or using mechanical structures such as a float valve. This is not part of the core content claimed in this application. Therefore, the formation scheme of the highest water level line 11 in water tank 1 will not be described in detail here.

[0049] In one specific embodiment, the exhaust pipe 5 and the upper section 321 of the water jet pipe 32 form an angle α, and the angle range is: 90°≥α≥0.

[0050] Specifically, by setting different angles, the discharge path of the gas after being compressed in the jet water pipe 32 can be optimized. When the water cover 41 and the water pump 2 jointly compress the gas, different angles can guide the gas into the exhaust pipe 5 in a more efficient manner to adapt to different installation spaces and exhaust requirements.

[0051] The operation of water pump 2 causes water to flow in the jet pipe 3. The water cover 41 of the flushing chamber 4, together with the water flow, compresses the gas inside the jet pipe 3. After being compressed, the gas enters the exhaust pipe 5 and is discharged according to the angle formed by the exhaust pipe 5 and the upper section 321 of the jet outlet pipe 32. For example, when the angle is small, the gas enters the exhaust pipe 5 quickly with a small bend; when the angle is large, the gas enters the exhaust pipe 5 after a certain bend and adjustment. In either case, the gas can be effectively discharged under the action of compression.

[0052] This design allows for flexible adjustment of the gas discharge path after compression, based on actual installation conditions and different usage requirements. By appropriately selecting the included angle, exhaust efficiency can be improved, ensuring that the compressed gas in the jet pipe 3 can be quickly and effectively discharged under various installation conditions. This guarantees stable operation of the flushing device, reduces flushing noise, and enhances the flushing effect.

[0053] In one specific embodiment, the upper section 321 and the lower section 322 of the water jet pipe 32 are connected by a connecting pipe 7, the air inlet end of the exhaust pipe 5 is connected to the connecting pipe 7, and the exhaust pipe 5 and the connecting pipe 7 are integrally formed.

[0054] Specifically, the exhaust pipe 5 and the connecting pipe 7 are integrally formed tee pipe structures, and the upper section 321 and the lower section 322 of the spray water pipe 32 are connected by the connecting pipe 7. This integral tee pipe structure reduces gaps at the connection points, enhances sealing, and ensures that when the water cover 41 and the water pump 2 compress gas, the gas can only be discharged through the exhaust pipe 5 and will not leak from the connection points. Furthermore, this design allows for the selection of tee pipes of different specifications and angles according to usage requirements, thereby flexibly adjusting the connection method and relative position of the exhaust pipe 5 and the spray water pipe 32 to meet different installation spaces and exhaust needs. For example, when the installation space is relatively narrow, a tee pipe with a smaller diameter and a suitable angle can be selected; when higher exhaust efficiency is required, a tee pipe with a more favorable gas discharge angle can be selected.

[0055] When the flushing device is running, water pump 2 pumps water, and the water surface 41 of the flushing chamber 4, together with the water flow, compresses the gas inside the spray pipe 32. Since the exhaust pipe 5 and connecting pipe 7 are integrally formed and connected to the spray pipe 32, the gas, after being pressurized, directly enters the exhaust pipe 5 through the connecting pipe 7 and then exits the device. In practical applications, by selecting a suitable tee pipe beforehand, the gas can be compressed and discharged along an efficient path, ensuring that the gas is discharged through the exhaust pipe 5 without leakage during the compression process.

[0056] The integrated three-way pipe structure not only enhances the sealing and stability of the venting device, effectively reducing the risk of poor venting due to air leakage at the connection points, but also provides flexible options. Compared to split or fixed connection structures, this design reduces installation complexity and improves production and installation efficiency. Furthermore, the characteristics of the appropriate three-way pipe can be selected according to usage requirements, ensuring the reliability of the venting function of the flushing device under the squeezing action of the water cover 41 and the water pump 2 in different usage scenarios, greatly improving the overall performance and applicability of the flushing device.

[0057] In one specific embodiment, the exhaust pipe 5 is connected to the water tank 1 at its outlet end and is higher than the highest water level line 11 of the water tank 1.

[0058] Specifically, connecting the exhaust pipe 5 to the water tank 1 not only allows the gas squeezed out by the water cover 41 and the water pump 2 to be discharged, but also ensures that the water in the spray pipe 3 flows fully into the water tank 1 after entering the exhaust pipe 5. The design of the water level being higher than the maximum water level 11 of the water tank 1 prevents water in the water tank 1 from flowing back into the exhaust pipe 5, ensuring the normal operation of the exhaust device; on the other hand, when a small amount of water enters the exhaust pipe 5, it can flow smoothly and fully into the water tank 1 under the action of gravity, maintaining the stable operation of the device.

[0059] When water pump 2 operates, the water cover 41 of the flushing chamber 4 and the water pumped into the jet pipe 3 together compress the gas. After the gas is discharged through the exhaust pipe 5, it enters the space above the water tank 1. Since the exhaust end of the exhaust pipe 5 is higher than the highest water level line 11 of the water tank 1, the water in the water tank 1 will not flow back into the exhaust pipe 5. After the water in the jet pipe 3 enters the exhaust pipe 5, the water will flow fully into the water tank 1 under the action of gravity. As the gas is continuously discharged, the gas pressure in the jet pipe 3 gradually balances, ensuring the smooth operation of the exhaust process and the entire flushing device.

[0060] This design ensures the rationality of gas emission and drainage, effectively avoiding the adverse effects of gas emissions into the external environment, such as odor diffusion. Simultaneously, the design's efficient water utilization ensures the normal operation of the exhaust system, improving the reliability and stability of the flushing device. When water enters the exhaust pipe 5, the efficient water utilization mechanism maintains device stability, reducing the problem of decreased flushing effect due to exhaust system malfunction.

[0061] In one specific embodiment, the water pump 2 is also connected to a washing pipe 8, the water outlet of which is connected to the upper end of the flushing chamber 4.

[0062] Specifically, after adding the washing pipe 8, the water pump 2 will split the water, with one part used for flushing the lower end of the spray pipe 3 and the other part used for flushing the upper end of the washing pipe 8. During this process, the water cover 41 of the flushing chamber 4 still works together with the two parts of water pumped out by the water pump 2 to compress the gas in the spray pipe 3, while the exhaust pipe 5 is responsible for discharging the pressurized gas.

[0063] After water pump 2 is started, the water in water tank 1 is divided into two parts. One part of the water flows through spray pipe 3 from the bottom to flush chamber 4, and the other part of the water flows through washing pipe 8 from the top to wash chamber 4. During the water flow, the water cover 41 of flush chamber 4 and the two water flows together compress the gas in spray pipe 3, and the gas pressure gradually increases. Finally, the gas is discharged through exhaust pipe 5, achieving a thorough cleaning of flush chamber 4 and effective gas discharge.

[0064] This design, by adding a flushing pipe 8, achieves comprehensive cleaning of the flushing chamber 4, while enhancing the compression effect of the water cover 41 and the water pump 2 on the gas, ultimately expelling the gas from the spray pipe 3. Compared to a simple bottom-flushing method, this significantly improves the cleaning ability and air venting efficiency of the flushing device, effectively removing dirt from all parts of the flushing chamber 4, reducing dirt residue, maintaining the cleanliness and hygiene of the bathroom fixtures, and enhancing the user experience.

[0065] In one specific embodiment, the exhaust pipe 5 is connected to the wash pipe 8.

[0066] Specifically, the exhaust end of the exhaust pipe 5 is connected to the washing pipe 8 to make reasonable use of the water flow in the washing pipe 8. This not only carries away the gas squeezed out by the water cover 41 and the water pump 2, further optimizing the gas discharge path, but also allows the water in the spray pipe 3 to flow fully into the flushing chamber 4 after entering the exhaust pipe 5, along with the water flow in the washing pipe 8. This design reduces the space occupied by setting up a separate gas discharge channel, while using the power of water flow to help the gas discharge more smoothly from the device and ensure that the water entering the exhaust pipe 5 can flow out smoothly and fully.

[0067] When water pump 2 operates, the water surface 41 of the flushing chamber 4, together with the water pumped into the jet pipe 3 and the washing pipe 8, compresses the gas. The gas is discharged through the exhaust pipe 5 and then enters the washing pipe 8. Driven by the water flow in the washing pipe 8, the gas follows the water flow and exits the device from the outlet end of the washing pipe 8. If water in the jet pipe 3 enters the exhaust pipe 5, the water will flow into the flushing chamber 4 along with the water flow in the washing pipe 8, thus making full use of the water and ensuring the normal operation of the entire flushing device.

[0068] This design simplifies the exhaust device structure, improves space utilization, and makes the flushing device layout more compact. Simultaneously, by utilizing the water flow in the wash pipe 8 to remove gas and fully utilize water, the exhaust effect is ensured, reducing the complex structure and installation problems that might arise from a separate exhaust channel, thus lowering production costs. When water enters the exhaust pipe 5, the device's stability is maintained through a full utilization mechanism, improving the overall performance and practicality of the flushing device.

[0069] In one specific embodiment, the inner diameter of the exhaust pipe 5 is 0.5mm-15mm.

[0070] Specifically, the reasonable setting of the inner diameter of the exhaust pipe 5 is to ensure that when the gas is squeezed together by the water surface 41 and the water pumped by the water pump 2, the gas can be discharged at an appropriate speed and flow rate, without affecting the overall structure of the flushing device and the hydrodynamics. If the pipe diameter is too small, the gas discharge resistance will be large; if the pipe diameter is too large, it may affect the stability of the water flow and the layout of the device.

[0071] During the flushing process, the water pump 2 pumps water, and the water cover 41 of the flushing chamber 4, together with the water flow, compresses the gas in the spray pipe 3. The pressurized gas is discharged through the exhaust pipe 5 with an inner diameter of 0.5mm-15mm. The appropriate inner pipe diameter ensures that the gas can be discharged smoothly, and the discharge process is coordinated with the water flow, without causing excessive interference to the water flow, thus ensuring the normal operation of the flushing device.

[0072] By controlling the inner diameter of the exhaust pipe 5 within a reasonable range, the normal function of exhaust is ensured under the squeezing action of the water cover 41 and the water pump 2, while maintaining the stable operation of the flushing device. This avoids the problem of poor exhaust caused by an excessively small pipe diameter, and also prevents the adverse effects of an excessively large pipe diameter on the water flow and device structure. While ensuring efficient exhaust, it also ensures the stability of the water flow and the overall performance of the flushing device.

[0073] In one specific embodiment, the output pipe 21 is provided with a first water outlet 211 and a second water outlet 212. The first water outlet 211 is connected to the washing pipe 8, and the second water outlet 212 is connected to the spray pipe 3.

[0074] Specifically, the output pipe 21 is equipped with dual outlets, connecting to the washing pipe 8 and the spray pipe 3 respectively, achieving efficient diversion of water from the pump 2. On the one hand, this simplifies the connection structure between the pump 2 and the pipes, reduces the number of components, lowers the risk of leakage, and improves the sealing and stability of the device. On the other hand, it precisely distributes the water flow, allowing the washing pipe 8 and the spray pipe 3 to obtain appropriate water pressure and volume as needed, meeting the different cleaning requirements of the upper and lower ends of the flushing chamber 4, and ensuring comprehensive and efficient cleaning. In addition, the integrated design saves space, facilitates installation and maintenance, optimizes the production process, reduces manufacturing and assembly costs, and improves the overall performance and practicality of the flushing device.

[0075] Preferably, the water pump 2 and the output pipe 21 are integrated into a single structure, significantly improving the reliability and compactness of the flushing device. This design reduces the number of interfaces in traditional separate connections, effectively reducing the risk of leakage and enhancing the device's sealing performance. Simultaneously, the integrated structure optimizes the water flow path, shortens the water transmission distance, reduces head loss, and allows the power of the water pump 2 to act more directly on the water flow, improving flushing efficiency and stability. Furthermore, this structure facilitates installation and maintenance, saves internal toilet space, simplifies the manufacturing process, and reduces manufacturing costs, combining functional and economic advantages to significantly enhance the product's market competitiveness.

[0076] In one specific embodiment, the water pump 2 is an axial flow pump or a centrifugal water pump 2.

[0077] Specifically, pump 2 can be either an axial flow pump or a centrifugal pump to adapt to different flushing scenarios. The axial flow pump features high flow rate and low head, enabling it to quickly pump large volumes of water, making it suitable for scenarios requiring powerful flushing of large areas of dirt, such as public restroom toilets, where it can quickly remove waste. The centrifugal pump 2 provides high head and stable pressure, suitable for scenarios requiring precise control of water flow impact, such as household toilets, ensuring thorough cleaning of all parts of the flushing chamber 4. Both pump types have mature technology systems, high reliability, and are easy to procure and maintain. Furthermore, this diverse selection optimizes the flushing device design, reduces production costs, improves the product's adaptability to different market demands, and enhances overall competitiveness. It is understood that in other embodiments, pump 2 can also adopt other suitable types and structures as needed.

[0078] See Figure 5 As shown, in a second aspect, this utility model embodiment also provides a flushing toilet, including the flushing device with an exhaust structure as described above, and also includes a toilet body 9, with a flushing chamber 4 disposed in the toilet body 9; the toilet body 9 is also provided with an installation cavity 91, and a water tank 1, a water pump 2, a jet pipe 3 and an exhaust pipe 5 are disposed in the installation cavity 91.

[0079] In this embodiment, the flushing device with an exhaust structure described above is integrated into the toilet body 9. The water tank 1, water pump 2, jet pipe 3, and exhaust pipe 5 are rationally arranged within the mounting cavity 91 of the toilet body 9. When the toilet is flushed, the water cover 41 of the flushing chamber 4 and the water pumped out by the water pump 2 together compress the gas inside the jet pipe 3, and the exhaust pipe 5 is responsible for expelling the gas, achieving efficient flushing.

[0080] When the flush button is pressed on the toilet, the flushing system is activated. Water in tank 1, driven by pump 2, is partially flushed from the bottom of the flushing chamber 4 via spray pipe 3, and the remaining water is flushed from the top of the flushing chamber 4 via wash pipe 8. During this process, the water cover 41 of the flushing chamber 4, together with the water flow, compresses the air inside the spray pipe 3. The air is then discharged through exhaust pipe 5, ensuring a stable water flow and effectively cleaning the toilet.

[0081] This toilet integrates a flushing device with an exhaust structure, utilizing the squeezing action of the water cover 41 and the water pump 2 to expel gas. It boasts excellent flushing performance, effectively reduces flushing noise, and ensures stable water flow. The comprehensive flushing method enhances cleaning effectiveness, provides users with a comfortable and convenient experience, and improves the overall quality and market competitiveness of the toilet.

[0082] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
