DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] To achieve the above object, the technical solution of the present invention is as follows:

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

[0037] Among them, the negative pressure flushing module includes:

[0038] Pressure tank for water storage 2;

[0039] One end thereof passes through the box 1 and is connected to the flushing pipe 3 of the toilet seat A;

[0040] One end thereof passes through the box body 1 and is connected to the negative pressure pipe 4 of the toilet seat A;

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

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

[0043] In this embodiment, the water supply pipe 5 is controlled by a pressure valve 6 to supply water to the pressure tank 2; the flush pipe 3 can flush the toilet seat A, and the negative pressure pipe 4 can provide a negative pressure effect in the toilet seat 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 seat A through the flush 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, the pressure tank 2 adopts a piston-type pressure tank, and a flushing control button (not shown) is installed on the box body 1, and the flushing control button is controlled and connected with the piston of the piston-type pressure tank 2. Similar to the existing piston-type flush tank, the flushing control button of the box body 1 is connected with the piston of the pressure tank 2 through a connecting rod. When the user uses it, he presses the flushing control button on the box body 1, and the piston moves in the pressure tank 2. The internal space of the pressure tank 2 is compressed to flush water. After releasing the flushing control button and the piston is reset, negative pressure will be generated on the top of the water tank, and air can be pumped through the negative pressure pipe 4 and the space of the toilet seat A, so that the toilet seat A forms a negative pressure environment, so that a very small amount of water can instantly fill the pipe of the flushing pipe 3 and form a strong siphon effect, thereby efficiently flushing away excrement and realizing negative pressure and efficient flushing.

[0046] Furthermore, the negative pressure flushing module also includes an air pump group 7 for providing a power gas source, a first pneumatic valve 8 is installed on the negative pressure pipe 4, a second pneumatic valve 9 is installed on the flushing pipe 3, and the first pneumatic valve 8 and the second pneumatic valve 9 are both connected to the air pump group 7. In the present application, the flushing control button installed on the pressure tank 2 is connected to the air pump group 7 through an electric control signal. When the flushing control button is pressed, the air pump group 7 controls the first pneumatic valve 8 and the second pneumatic valve 9 to open to achieve flushing.

[0047] Furthermore, the first pneumatic valve 8 is a three-way valve, two of which are used to connect to the negative pressure pipe 4, and the last one is used to connect to the exhaust deodorization module. The negative pressure pipe 4 has an auxiliary deodorization function and can discharge the odor in the toilet seat A through the exhaust deodorization module through negative pressure.

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

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

[0050] Furthermore, the exhaust deodorization module includes a fan 10, which is installed in the box 1, and the flushing pipe 3 is connected to the air inlet of the fan 10 through a pipeline.

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

[0052] Furthermore, the exhaust and deodorization module also includes a trash can reserved pipe opening 13 for sucking odor from the trash can and a room reserved pipe opening 14 for exhausting air from the room. One end of the trash can reserved pipe opening 13 and the room reserved pipe opening 14 are connected to the air inlet of the fan 10, and the other end passes through the outside of the box 1.

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

[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 adopt a control PCB board. The air pump group 7, the flushing control button, and the fan 10 are all connected to the control module, and the coordinated work between the air pump group 7, the flushing control button, and the fan 10 can be electrically controlled.

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

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

[0057] In this embodiment, the process of negative pressure flushing is as follows: the water supply pipe 5 injects water into the pressure tank 2 through the pressure valve 6. When a certain pressure is reached, the water injection pressure valve 6 is automatically closed to form a high-pressure environment in the 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 the pressure tank 2. High pressure is formed at the bottom of the pressure tank 2, and suction is formed on the upper part due to the pressure difference. This suction can enable a very small amount of water to fill the pipe of the flushing pipe 3 in an instant and form a strong siphon effect, thereby efficiently flushing away excrement, achieving an efficient flushing effect, and a significant water saving rate.

[0058] The deodorization working process is: when the negative pressure flushing is working, the fan 10 is automatically turned off. After the flushing work is completed, the control module controls the fan 10 to work, and the internal gas of the toilet pipe is extracted through the flushing pipe 3, and then discharged through the flat air vent after being filtered by the filter element 11. The flat air vent is used to adapt to the use of limited equipment space.

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

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

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

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

[0063] Odor-free environment: The exhaust deodorization module can quickly remove the odor in toilet A after flushing. The odorous air is sucked into the deodorization system through the fan 10, and the odor molecules are effectively adsorbed after multi-layer filtration by the activated carbon filter element 11. Finally, the fan 10 discharges the purified air through the flat air outlet. The system can reduce the odor concentration in toilet A to below 0.1ppm within 30 seconds after flushing, meeting the international air quality standards, significantly improving the user experience of the bathroom, and is particularly suitable for places with high requirements for air quality, such as hospitals, hotels and high-end residences.

[0064] Compact structure: The box 1 is small in size, easy to install, and suitable for a variety of scenarios. The box 1 of the present invention is only 550*750*150mm in size, with a compact structure design and flexible and convenient installation. The system can be installed independently, saving space without affecting the overall appearance. This compact and flexible design enables the present invention to be widely used in a variety of scenarios such as homes, public places, temporary facilities, etc., to meet the needs of different users.

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