Description

Technical Field

[0001] This utility model belongs to the field of sanitary ware technology, and specifically relates to a negative pressure water-saving and odorless toilet system. Background Technology

[0002] Traditional toilet flushing systems typically use water to directly flush the toilet, which results in high water consumption and odor residue. Each flush requires a large amount of water, failing to meet water conservation requirements. Furthermore, odors often remain in the bathroom after flushing, affecting the user experience.

[0003] Although some existing toilet systems use negative pressure flushing, such as the water-saving negative pressure toilet disclosed in application number 202021563270.0, which is adaptable to multiple operating modes, it includes a toilet bowl, a water inlet system, and a drainage system. The upper inner side of the bowl wall is provided with a water distribution groove, one end of which is provided with a water inlet, and the bottom of the bowl is provided with a drain outlet. The water inlet system is provided with a water inlet solenoid valve, whose water source side port is used to connect to the water supply pipe, and its toilet side port is used to connect to the toilet's flushing pipe. The drainage system is provided with a negative pressure valve, whose negative pressure side port is used to connect to a negative pressure sewage pipe, and its toilet side port is connected to the drain outlet. The control end interface of the negative pressure valve is connected to a negative pressure controller. The flushing nozzle is located at the water inlet end of the water distribution groove and connected to the flushing pipe, which can realize negative pressure sewage discharge of the toilet and effectively reduce the water consumption for flushing.

[0004] Although the water-saving negative pressure toilet disclosed in the above patent can reduce water consumption by draining water through negative pressure, it still has the problems of complex structure, high cost, and inability to deodorize. Utility Model Content

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] To achieve the above objectives, the technical solution of this utility model is as follows:

[0036] See Figure 1 As shown, this embodiment provides a negative pressure water-saving and odorless toilet system, including: a housing 1, a negative pressure flushing module, and an exhaust and deodorization module;

[0037] The negative pressure flushing module includes:

[0038] Pressure tank 2 for water storage;

[0039] One end of the flush pipe 3 passes through the box 1 and connects to the toilet stall A;

[0040] One end of the negative pressure pipe 4 passes through the box body 1 and connects to toilet stall A;

[0041] A water supply pipe 5 is used to supply water to pressure tank 2, and a pressure valve 6 is installed on the water supply pipe 5.

[0042] Pressure tank 2 is installed inside box 1. The ends of flush pipe 3 and negative pressure pipe 4 away from toilet A are connected to pressure tank 2. One end of water supply pipe 5 is connected to pressure tank 2, and the other end passes through box 1 and is connected to an external water source. The flush pipe 3 is connected to the exhaust and deodorization module through a pipe.

[0043] In this embodiment, the water supply pipe 5 is controlled by the pressure valve 6 to supply water to the pressure tank 2; the flushing pipe 3 can flush the toilet stall A, and the negative pressure pipe 4 can provide a negative pressure effect in the toilet stall A to achieve efficient negative pressure flushing and reduce water consumption; after flushing, the exhaust and deodorization module can extract the odor in the toilet stall A through the flushing pipe 3 to achieve deodorization.

[0044] Furthermore, the upper end of the negative pressure pipe 4 is connected to the top of the pressure tank 2, and the lower ends of the flushing pipe 3 and the water supply pipe 5 are both connected to the bottom of the pressure tank 2.

[0045] Furthermore, pressure tank 2 is a piston-type pressure tank, and a flush control button (not shown) is installed on the housing 1. The flush control button is connected to the piston of the piston-type pressure tank 2. Similar to existing piston-type flush tanks, the flush control button on the housing 1 is connected to the piston of the pressure tank 2 via a connecting rod. When the user uses the tank, pressing the flush control button on the housing 1 moves the piston inside the pressure tank 2, compressing the internal space of the pressure tank 2 and flushing. Releasing the flush control button resets the piston, creating negative pressure at the top of the tank. This creates a vacuum between the negative pressure pipe 4 and toilet stall A, resulting in a negative pressure environment in toilet stall A. This allows a very small amount of water to instantly fill the flush pipe 3 and create a strong siphon effect, efficiently flushing away waste and achieving efficient negative pressure flushing.

[0046] Furthermore, the negative pressure flushing module also includes an air pump unit 7 for providing a power source. A first pneumatic valve 8 is installed on the negative pressure pipe 4, and a second pneumatic valve 9 is installed on the flushing pipe 3. Both the first pneumatic valve 8 and the second pneumatic valve 9 are connected to the air pump unit 7. In this application, the flushing control button installed on the pressure tank 2 is connected to the air pump unit 7 via an electrical control signal. When the control button is pressed, the air pump unit 7 controls the first pneumatic valve 8 and the second pneumatic valve 9 to open, thereby achieving flushing.

[0047] Furthermore, the first pneumatic valve 8 is a three-way valve, with two ports used to connect to the negative pressure pipe 4 and the last port used to connect to the exhaust and deodorization module. The negative pressure pipe 4 has an auxiliary deodorization function, which can use negative pressure to expel odors in toilet A through the exhaust and deodorization module.

[0048] Furthermore, both the first pneumatic valve 8 and the second pneumatic valve 9 are ball valves with an inner diameter of 32mm.

[0049] Furthermore, the inner diameter of the negative pressure pipe 4 and the flushing pipe 3 is 32mm, and the inner diameter of the water supply pipe 5 is 48mm.

[0050] Furthermore, the exhaust and deodorization module includes a fan 10, which is installed inside the housing 1. The flushing pipe 3 is connected to the air inlet of the fan 10 via a pipe.

[0051] Furthermore, the exhaust and deodorization module also includes a filter element 11 and a flat duct 12. The filter element 11 is installed at the air inlet of the fan 10, and the flat duct 12 is installed at the air outlet of the fan 10. The end of the flat duct 12 away from the fan 10 extends out of the housing 1. The filter element 11 can filter the gas entering at the air inlet and then discharge it through the flat duct 12.

[0052] Furthermore, the exhaust and deodorization module also includes a garbage can reserved pipe 13 for sucking up odors from the garbage can and a room reserved pipe 14 for exhausting air into the room. One end of the garbage can reserved pipe 13 and the room reserved pipe 14 are connected to the air inlet of the fan 10, and the other end extends out of the box 1.

[0053] Furthermore, the diameter of the reserved pipe opening 13 in the trash can and the reserved pipe opening 14 in the room are both 50mm.

[0054] Furthermore, the system also includes a control module (none) for coordinated control of the flushing control button, the air pump group 7, and the fan 10. The control module can be a control PCB board. The air pump group 7, the flushing control button, and the fan 10 are all connected to the control module, which can electrically control the coordinated operation of the air pump group 7, the flushing control button, and the fan 10.

[0055] Furthermore, the housing 1 is also provided with an inlet hole 15 for the external power supply line. The external power supply line passes through the inlet hole 15 and connects to the control module to provide power to the negative pressure water-saving and odorless toilet A system.

[0056] Furthermore, the height, width, and thickness of the box 1 are 550, 750, and 150 mm, respectively.

[0057] In this embodiment, the negative pressure flushing process is as follows: water supply pipe 5 injects water into pressure tank 2 through pressure valve 6. When a certain pressure is reached, water injection pressure valve 6 automatically closes, creating a high-pressure environment in pressure tank 2. When the user presses the flushing control button to flush, the control module receives the control signal and controls the air pump group 7 to work. The air pump group 7 opens the first pneumatic valve 8 and the second pneumatic valve 9 on the upper and lower sides of pressure tank 2. High pressure is formed at the bottom of pressure tank 2, and suction is formed at the top due to the pressure difference. This suction allows a very small amount of water to fill the flushing pipe 3 instantly and form a strong siphon effect, thereby efficiently flushing away the excrement and achieving a high-efficiency flushing effect with a significant water saving rate.

[0058] The deodorization process is as follows: When the negative pressure flushing is working, the fan 10 will automatically turn off. After the flushing is completed, the control module will control the fan 10 to work and extract the gas inside the toilet pipe through the flushing pipe 3. After being filtered by the filter element 11, the gas will be discharged through the flat air outlet. The flat air outlet is used to adapt to the scenario where the equipment space is limited.

[0059] It should be noted that the control module in this embodiment belongs to the prior art. Its coordinated control between the electronic control button for flushing water control, the air pump group 7, and the fan 10 is common in industrial control and is not the content that this application intends to protect. Its specific implementation method will not be described in detail in this application.

[0060] Further, see Figure 2-3The negative pressure water-saving and odorless toilet system in this embodiment can be applied to various toilet environments such as squat toilets and seated toilets.

[0061] Compared with the prior art, the advantages of this embodiment are:

[0062] High efficiency and water saving: Through the synergistic effect of pressure tank 2 and pneumatic ball valve, a strong negative pressure effect is formed during flushing, which can achieve efficient flushing with only 40% of the water used in traditional toilet flushing, and the water saving rate can reach more than 60%. This not only significantly reduces water consumption, but also reduces the burden on the drainage system. It is suitable for water-scarce areas and high-frequency public places, such as schools, shopping malls and transportation hubs.

[0063] Odorless Environment: The exhaust deodorization module can quickly remove odors from toilet stall A after flushing. Odor-laden air is drawn into the deodorization system by the fan 10, and after passing through multiple layers of filtration by the activated carbon filter 11, odor molecules are effectively adsorbed. Finally, the purified air is discharged through the flat vent by the fan 10. The system can reduce the odor concentration in toilet stall A to below 0.1 ppm within 30 seconds after flushing, meeting international air quality standards and significantly improving the user experience of the bathroom. It is especially suitable for places with high air quality requirements, such as hospitals, hotels, and high-end residences.

[0064] Compact Structure: The housing 1 is small in size, easy to install, and suitable for various scenarios. The housing 1 of this invention measures only 550*750*150mm, featuring a compact structure and flexible, convenient installation. The system can be installed independently, saving space without compromising overall aesthetics. This compact and flexible design allows the invention to be widely used in various scenarios such as homes, public places, and temporary facilities, meeting the needs of different users.

[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
