As shown in fig. 1 to 6, the present application provides a toilet device 100, which can be used in a suction type intelligent toilet, a sitting type toilet, or a squatting type toilet.

As shown in fig. 1, the present embodiment is described in detail with reference to a sitting type toilet apparatus 100. The toilet device 100 includes a toilet main body 1, and a flushing system 2 installed to cooperate with the toilet main body 1.

As shown in fig. 2, the toilet body 1 includes a toilet bowl 10 and a base 11. The toilet bowl 10 is provided with first and

second spray openings

101 and 102 and a drain opening 103. The first and second

spray rinsing ports

101 and 102 are connected to the flushing system 2 for cleaning the toilet body 1, and the drain port 103 is connected to the sewer system for discharging the cleaned contents.

The toilet body 1 comprises a front end 1a and a rear end 1b opposite to the front end 1a, and the rear end 1b can be arranged corresponding to the mounting surface of the wall. The first spray opening 101 is disposed at the front of the toilet bowl 10, and the second spray opening 102 is disposed at the rear and the first spray opening 101 in the front-rear direction of the toilet body 1. The first and

second spray ports

101 and 102 are located at an upper portion of the toilet bowl 11 in a height direction of the toilet body 1.

In one exemplary embodiment, the first spray opening 101 includes a plurality and is arranged along the circumferential direction of the toilet bowl 10; the second spray ports 102 include a plurality of ports and are arranged along both sides of the circumference of the toilet bowl 10, thereby enabling a better washing effect.

The toilet bowl 10 has an arc-shaped front part 104, an arc-shaped rear slope 105 of an inclined design, and a water-sealing region 106 at the bottom. The arc-shaped front part 104, the inclined rear slope 105 forms a main chamber extending from the top to the bottom, the arc-shaped front part 104 is shaped to provide a space for receiving urine, and the rear slope 105 is inclined forward gradually from the top to the bottom in the height direction of the toilet body 1 to avoid contact with solid contents during defecation. The water seal zone 106 continues in a turn along the lower portion of the main chamber and extends towards the rear or side of the toilet bowl 10. The drain outlet 103 is provided at the rear or side of the toilet bowl 10 and communicates with the 106 water-sealed area. The water seal 106 has a transverse cylindrical storage space that stores a volume of water, prevents the suction device 12 from contacting solids, and prevents odorous particles from adhering to the ceramic. The water seal 106 stores a basic water level connected to a space where the rear slope 105 of the toilet bowl 10 is to be turned, and when the flushing is performed, the rising portion of the liquid level levels a portion between the basic water level and the rear slope 105 of the toilet bowl to remarkably lift the water. The design of the back ramp 105 can facilitate the collection of liquid and paper. The design of the closestool cylinder of the embodiment of the application can obviously improve the water level, gather the content and avoid the solid in the sewage discharge process from being stuck on the closestool wall.

The design of the toilet bowl 10 of the present embodiment reduces the need for higher hydraulic power (flow and pressure) and allows toilet paper on a slightly falling wet slope to be flushed away by the force of the flushing water stream alone. In addition, the water seal area 14 can store a higher water level, and the content can be more easily washed away.

As shown in fig. 1 and 2, the toilet device 100 further includes a suction device 12, and the suction device 12 is installed in cooperation with the sewage draining outlet 103 for generating negative pressure to discharge the contents in the toilet bowl 10. The suction device 12 of the present embodiment may employ a dip pump, and in other embodiments, a vacuum pump or the like may be employed.

As shown in fig. 2, the toilet device 100 further includes a backflow prevention device 13, which is an anti-backflow valve used in this embodiment, provided at an outlet of the suction device 12. The suction device 12 is fitted with the sewage discharge opening 103 of the toilet body 1 through a flange type connector 14, and the flange type connector 14 integrates an O-ring seal and a connection screw (not shown) fixed to the ground. The suction device 12 can not only suck liquid and solid, but also process, stir and crush solid and toilet paper.

In this embodiment, the anti-backflow valve 13 is reinforced at the outlet of the suction device 13 by a magnetically attractive element 130. When the suction device 12 works, the anti-backflow valve 13 is automatically opened under the pushing of the sucked object; after the suction device 13 is stopped, the anti-backflow valve 13 is automatically closed to seal the toilet bowl 10 from the sewage. The anti-return valve 13 is provided with a closing means (not shown) so that the water level rising at one side of the toilet bowl 10 does not open the anti-return valve 13, requiring a water column pressure higher than the pressure of the clogging water in the toilet to open the anti-return valve 13. The magnetically attractive element 130 is fixed at a predetermined height and is opened at a higher water level or the discharge system forces it open. The suction device 12 has a higher force than the resistance to opening the anti-reflux valve 13, preventing the emulsion from flowing away during manual introduction of liquid or solid. The operating time of the suction device 12 is set according to the time of emptying the toilet.

In another embodiment, the magnetic device 130 on the anti-reflux valve 13 will open the anti-reflux valve 13 by opening a circuit of the control device 24 (the control device 24 of the flushing system 2 described below).

As shown in fig. 4, the toilet body 1 of the embodiment of the present application may be a split type including a main body and a base, which may be assembled with each other. The base is shown schematically, and the suction device 12 is arranged on the base so as to be quickly adapted to a squatting pan.

As shown in fig. 1, the flushing system 2 includes a first spraying pipeline 21 and a second spraying pipeline 22, an on-off assembly 23 connected to the first spraying pipeline 21 and the second spraying pipeline 22, and a control device 24 connected to the on-off assembly 23 for controlling the on-off assembly 23 to open and close. The first spray pipe 21 is installed to be matched with the first spray opening 101 of the toilet body 1, and the second spray pipe 22 is installed to be matched with the second spray opening 102.

As shown in fig. 2, the water outlet end (front end) of the first spray pipe 21 is provided with a first nozzle 210, and the first nozzle 210 is located at the front end of the toilet bowl 10 for washing toilet paper that the user has lost, and is installed in cooperation with the first spray opening 101. As shown in the figure, the water sprayed from the first nozzle 210 should enter the horizontal column-shaped storage space of the water-sealing section 106 along the curve of the slightly descending front end of the toilet bowl 10. The first nozzle 101 has a horizontal section 2101 and a bending section 2102 bending towards the inside of the toilet bowl 10, the horizontal section 2101 guides the sprayed water to be horizontally conveyed to a position close to the front wall surface, and the bending section 2102 sprays the water to the wall surface of the toilet bowl 10, so that dirt stuck on the inner wall of the toilet can be effectively cleaned. The water outlet end of the second spray pipe 22 is provided with a second nozzle 220, and the second nozzle 220 is located on the side or back of the toilet bowl 10, and is installed to clean the inner wall of the rear part of the toilet bowl 10 in cooperation with the second spray port 102, so as to clean the toilet bowl 10 from the adhesive particles.

To enhance cleaning, the first nozzle 210 and the second nozzle 220 may be operated alternately, e.g., from left to right, or pulsed rinsing, etc. The first nozzle 210 and the second nozzle 220 are interchangeable according to the available water supply pressure and flow, the spraying angle and the spraying direction of the first nozzle 210 and the second nozzle 220 to the bowl wall can be changed, referring to fig. 2 and 3, the spraying angle of the second nozzle 220 to the side wall of the toilet bowl 10 is about 10 degrees, the spraying coverage is about 45 degrees, and the specific setting can be carried out according to the actual situation. The first nozzle 210 and the second nozzle 220 should be integrated with threads having sealing rings so as to be connected to the supply pipes of the first spray line 21 and the second spray line 22. The first nozzle 210 and the second nozzle 220 may have various shapes such as a circle, a flat shape, and the like. The first nozzle 210 can completely clean the inner wall of the front portion of the toilet bowl 10. The second nozzle 220 is angularly disposed so that the flushing range is sufficient to cover the entire toilet bowl 10.

In order to improve the performance of the cleaning nozzle, the first nozzle 210 and the second nozzle 220 are not fixed on the inner wall of the toilet bowl 10 but are positioned below the upper edge of the toilet bowl 10 at a small distance from the inner wall, and the spray does not flow parallel to the inner wall but forms a certain angle with the inner wall, thereby increasing the range of spray coverage by the change of the angle, and thus improving the cleaning effect of the system.

The primary purpose of the first nozzle 210 is to flush out solid objects such as toilet paper that the user drops after urinating and cleaning with paper. The first nozzle 210 enters the water seal area 106 along the curve of the slightly descending front end of the toilet bowl. The direction of the first nozzle 210 directs the emitted water stream parallel to the surface. The second nozzle 220 mainly cleans the inner wall of the rear portion of the toilet bowl 10 because of the possibility of contacting sticky particles. To enhance the cleaning effect, the nozzles are operated alternately (from left to right, or pulsed) with the second nozzles 220 on both sides.

In this embodiment, the on-off assembly 23 employs an electric control valve, and the first injection pipeline 21 and the second injection pipeline 22 are respectively provided with one electric control valve: a first electric control valve 23a and a second electric control valve 23b. In other embodiments, the first injection line 21 and the second injection line 22 may also use an integrally disposed electrically controlled valve, which is not limited herein.

As shown in fig. 1, the flushing system 2 further includes a pressurizing device 25 disposed in the first spray line 21 and the second spray line 22, for pressurizing the spray water in the first spray line 21 and the second spray line 22, so as to provide a better flushing effect. In the figure, three water paths a, B and C are shown as examples of three water supplies, and any one of the three water paths can supply water to the first spray pipe 21 and the second spray pipe 22. The water path A adopts a pressurized water tank for water supply, the water path B adopts a booster pump for water supply, the water path C adopts the booster pump and the gas-liquid mixing tank 28 for water supply, and the three water supply water paths can supply water independently or can be mutually combined for water supply without limitation.

When the pressurizing means 25 employs a gravity flush tank, the water inlet ends of the first and

second spray lines

21 and 22 communicate with the gravity flush tank 25. The gravity flush tank 25 is suspended at a height relative to the toilet body 10 such that pressure is provided only by the gravity of the water in the tank 25.

When the pressurizing means 25 employs a booster pump, the booster pump directly pressurizes the water in the first and

second shower lines

21 and 22.

As shown in fig. 1, the control device 24 includes a control unit (not shown), and an operation panel connected to the control unit, and operation keys (e.g., F, M, S, and B shown in fig. 1) are provided on the operation panel. The control key can be a physical key, can also be a touch key, can be designed as a press switch, and can also be designed as a microswitch integrated in a panel. An operating panel can be placed above the toilet body 1, the switches being connected to a control unit with a program (Arduino) to parameterize the different flushing programs. The control device 24 may also be presented on the terminal through a user interface, which may be that of a sitting or squatting toilet.

In this embodiment, the control unit 24 controls the

electric control valves

23a and 23b and the suction unit 14 to open and close, open and close at different times, and in sequence with the emptying of the toilet bowl, according to the different flushing command signals received. In different flush modes, the flush system 2 achieves effective flushing by setting the time sequence for flushing, emptying and refilling the toilet so as to lift the water in the toilet to different levels to maintain the correct solids to liquid ratio.

Toilets in the prior art generally use two flush modes: one for solids (feces) and the other for liquids (urine). Liquid rinses typically contain only half the volume of a full rinse, with water volumes between 2.5 and 3 liters per use by both male and female users. The flush of the european toilet is specified by EN 997 standard, with a main flush volume of about 6 litres and a us HET standard of 4.8 litres per flush.

It is well known that male and female users will have different practices after urination. Urination without toilet paper, usually male users; it is a female user to use toilet paper for urination and growth. Since a male user flushes directly after each urination, a female user needs toilet paper after the urination is finished, which means that the female user needs more water to wash the toilet paper in the toilet. The advantage of this is that male users have a water saving potential of about 50% when washing urine compared to female users, since there is no need to wash toilet paper with water. The flush water need only flush the ceramic surface and refill the contents of the water siphon.

Therefore, the toilet device 100 of the embodiment of the present application divides the liquid flushing into two flushing modes, the first flushing mode: is suitable for male to wash without paper liquid; a second flush mode: is suitable for women to wash with paper liquid.

The first mode is suitable for the paperless liquid flushing of men and the operation method is as follows:

after toileting, the user presses a button with a male flush action (the button may be prompted with the symbol M) to trigger a first flush command (low voltage pulse signal). The control unit 24 of the irrigation system receives a first irrigation command, activates the suction unit 12 to aspirate the contents, while the anti-reflux valve 13 is automatically opened. When the suction device 12 is activated for a first predetermined emptying time and then stopped, the anti-reflux valve 13 closes to prevent water from the sewer from flowing back to the water seal area 106 of the toilet.

After the suction device 12 stops emptying for the second predetermined time, the first control valve 23a is opened, the first spray line 21 delivers water, the first nozzle 210 of the first spray line 21 sprays water, the front portion of the toilet bowl 10 is wetted for cleaning, and the water sealing area 106 is replenished with about 200 ml of flush water until the first predetermined level L1 is reached to cover the water sealing area 106 and thus the portion of the suction device 12 in contact with the contents. Of course, the water amount in the water seal area 106 can be replenished through the second spray line 22, and the water seal area 106 can be replenished through the second spray line 22 in any of the following modes, which are not limited herein.

The liquid level of the toilet body 1 may be calculated by the opening time of the first control valve 23a, or may be detected by a liquid level sensor disposed in the toilet body 1, which is not limited herein.

The specific control method of the first mode can refer to table one, wherein X represents a time variable, s represents seconds, and the corresponding time can be set through software. This table is a typical flushing program logic setup diagram.

Watch 1

When the toilet is ready to be used, the initial basic water level L1 is set in the toilet, the water level rises to LM after a user uses the toilet, the user presses the flushing button to directly suck and empty, and the toilet is flushed to the filling water level L1 after a short time. The rest time setting is mainly aimed at: the filling process can only be started after the process of sucking away the excrement is completely finished. A short neutral time is needed in the middle, otherwise the pump does not know when to stop.

The second mode is suitable for the flushing of the paper liquid for women, and the specific operation method is as follows:

since the female user uses toilet paper after urination, the paper is likely to be lost in the front of the bowl 10, and thus the flush volume must be such that the paper can be flushed to the water containing portion of the toilet before it can be discharged. After toileting, the user presses the button with the female flushing operation (the button may be prompted with symbol F) to trigger a second flushing command (low voltage pulse signal).

The control device 24 receives the second flushing command, controls the control valve 23a to open the first spray line 21, and the water is sprayed from the first nozzle 210, about 400 ml. The first nozzle 210 is installed at the front of the toilet bowl 10 near the front wall of the toilet bowl, and makes the toilet paper enter the lower part of the toilet bowl 10 from the front of the toilet bowl 10 to wash the toilet paper toward the water sealing area of the toilet bowl 10, and the water level rises to a second predetermined level L2, and the paper in the toilet bowl 10 can float on the water surface, and the water level in the toilet bowl 10 is higher than the lower end position of the rear slope 105 of the toilet bowl 10.

When the water level rises to the second predetermined level L2, the control device 24 controls the suction device 12 to be turned on, and the suction device 12 sucks out the liquid with the floating toilet paper. After a third predetermined emptying time has been initiated after the operation of the suction device 12, and during the initiation of the suction device 12, the control device 24 controls the control valve 23a to close. The suction device 12 and the first spray line 21 are operated simultaneously for a period of time.

When the water in the toilet bowl 10 is evacuated, the suction device 12 is stopped, the control device 24 controls the control valve 23 to open again to open the first spray line 21 until the water level in the water-sealing region 106 reaches the first predetermined level L1 of about 200 ml of water to cover the parts of the suction device 12 in contact with the excrement, and the anti-reflux valve 13 is closed to prevent the gas from the waste water pipe from entering. The specific control process can refer to the second table.

Watch two

When the toilet is ready to be used, the initial basic water level L1 is set in the toilet, the water level rises to LF after a user uses the toilet, the user presses the flushing button to flush, the water level rises to L2 to perform suction and emptying, and the toilet is flushed to the filling water level to L1 after a short time.

Water analysis for the second flush mode: the total volume drained was about 200 ml urine, 400 ml water for paper rinsing, and 200 ml water for refilling the bottom of the toilet bowl about 800 ml.

The toilet device 100 of the embodiment of the present application also sets a third flushing mode: is suitable for male or female after discharging solid feces.

Two objectives to be achieved in the third flush mode are that, firstly, when discharging the solid as a liquid emulsion, more water is added to the bowl 10 to dilute the solid, so that the flush volume is higher than in the second flush mode, and the suction device 12 is activated at a third predetermined level L3; secondly, cleaning stains on the toilet bowl 10. The specific operation method comprises the following steps:

after toileting, the user presses a solid (feces) flush button with pressurization function (the button may be prompted with the symbol S) with male and female to trigger a third flush command.

The control device 24 receives the third flushing command, and controls the first control valve 23a and the second control valve 23b to open the first spray line 21 and the second spray line 22 for the first predetermined flushing time and then close. The water is jetted from the first nozzle 210 of the first spray line 21 and the second nozzle 220 of the second spray line 22 to be washed toward the wall surface of the toilet bowl 10 until the water flow increases to a third predetermined level L3 to the extent that the solid is partially covered with the washing water and the toilet paper can be floated.

While the water is still being flushed, the suction device 12 activates the contents of the suction cylinder and stops after a fourth predetermined evacuation time. The opening time of the first nozzle 210 and the second spray line 22 when the suction device 12 is in operation is defined as a first predetermined duration. The first and

second spray lines

21 and 22 are stopped before the suction means 12 is stopped, in order to allow the contents of the toilet bowl 10 to be completely sucked out.

After the suction device 12 stops sucking, the first spray line 21 is opened to fill the toilet bowl 10 with water, rising again to the first predetermined level L1. The specific control method can be referred to table three.

Watch III

When the closestool is ready for use, the initial basic water level L1 is set in the closestool, the water level rises to Ls after a user uses the closestool, the user presses a flushing button, two nozzles flush the closestool, the water level rises to L3, then suction emptying is carried out, when emptying, the two nozzles flush a period of time, and after the closestool is emptied for a short time, the closestool flushes the filling water level to L1.

Water usage analysis for the third flush mode: 600 ml for cleaning the bowl walls and flushing the paper and 200 ml for replenishing the toilet and cleaning the front of the toilet. The input of solids and liquid was about 350 ml. The fill water (200 ml) was left in the lower part of the toilet bowl for the next use. The total volume to be treated was 950 ml of liquid (about 80% of the liquid in the feces).

The toilet device 100 of the embodiment of the present application further sets a fourth flushing mode: suitable for use in pressurized irrigation for private residential and commercial or public applications.

The fourth flushing mode may be an additional function of the third flushing mode, and is mainly different from the third flushing mode in that when the fourth flushing mode is opened, the opening time of the first control valve 23a and the second control valve 23b is prolonged by about 30%, so that the flushing amount is increased, and the opening time of the suction device 12 is relatively prolonged.

The opening time of the first and

second control valves

23a and 23b is defined as a first predetermined flushing time. The first nozzle 210 and the second spray line 22 are open for a second predetermined duration when the suction device 12 is in operation, the second predetermined duration being greater than the first predetermined duration of the third flush mode.

The suction device 12 is activated for a fifth predetermined emptying time, which is greater than the fourth predetermined emptying time. When the liquid level reaches the third predetermined liquid level L3, the suction device 12 may be started and may calculate according to the opening time of the first control valve 23a and the second control valve 23b, or may detect according to a liquid level sensor, which is not limited herein.

In addition, a fourth flush command corresponding to the fourth flush mode is triggered by the user pressing a flush button with a pressurized flush (the button may be prompted with symbol B). Fourth flushing mode the remaining operation steps can refer to the third flushing mode, which is not described herein.

To avoid the danger of water volume exhaustion due to overuse, the flushing system is provided with a reminding function. The first reminding mode is as follows: by providing a first sensor 26 in the water tank 25 connected to the control device 24 for detecting the water level, when the water level of the water tank 25 does not match the water consumption curve, an indicator light is provided for warning. The control device 24 stores a water consumption curve in advance, collects and calculates water consumption data of the water tank 25 to determine whether the water consumption data are matched, and reminds an indicator light when the water consumption data are not matched. The second reminds the mode can mark the interior suggestion of closestool jar and use the pressure boost to wash the water level that washing button B corresponds, through the pilot lamp suggestion can. The pressure increasing switch B adopts the change of an indicator light to prompt the user to operate.

The toilet apparatus 100 of the embodiment of the present application further sets a fifth flushing mode: a fully automatic full flush, suitable for use in public or commercial applications where the user is unfamiliar with the flushing procedure of the fourth flush mode, can be used to treat higher than usual volumes of solids (faeces) in the toilet bowl. A larger volume of water (e.g., 800 ml, rather than 600 ml) is injected due to the larger volume of solids being discharged.

The toilet bowl 10 is provided at the rear with a second liquid level sensor 27 for sensing the input of solid and liquid, and when the control unit 24 receives the input of solid and liquid exceeding a predetermined value, the fifth flushing mode is selected to be activated.

Illustratively, when about 170g of solids are input, the water level of the toilet bowl 10 is raised to the high water level of the toilet bowl. If more than 200 ml of urine and more than 170 ml of typical solids volume, the second level sensor 27 may detect an input above a predetermined level and may adjust the flush volume accordingly, meaning that a fifth flush mode will be performed.

The fifth flushing mode may be an automatic flushing mode, which is different from the fourth flushing mode mainly in that: this mode may be achieved without requiring a button operation by the user, and the fifth flush command of the control device 24 for turning on the fifth flush mode is obtained by the second liquid level sensor 27, and when the second liquid level sensor 27 senses that the solid and liquid inputted into the toilet bowl exceed a predetermined value (generally, the water level exceeds a predetermined value), the fifth flush mode is selected to be activated.

Starting a fifth flushing mode, wherein the control device 24 controls to open the first and

second spraying pipelines

21 and 22 for a second preset flushing time, and the second preset flushing time is longer than the first preset flushing time;

when the liquid level in the toilet bowl 10 reaches a fourth preset liquid level, the control device 24 controls the suction device 12 to start and stop after a sixth preset emptying time; the first and

second spray lines

21, 22 are closed before the suction device 12 is deactivated, and the first and

second spray lines

21, 22 continue to be open at the suction device 12 for a third predetermined duration. The fourth predetermined level is greater than the third level, the sixth predetermined drain time is greater than the fifth predetermined drain time, and the third predetermined duration is greater than or equal to the first predetermined duration.

When the suction device 12 stops sucking, the first spray line 21 is opened again, and when the liquid level in the toilet bowl 10 reaches the first predetermined liquid level L1, the first spray line 21 is closed.

In order to distinguish between the flushing water and the rising waste liquid level in the toilet bowl 10, the second sensor 27 is turned off when the flushing operation is performed and the liquid flows in (urinates) from the top down. For example, when the amount of change of the liquid increase in the toilet bowl is greater than a preset value, the detection is stopped, and when a flushing signal is received, the detection is started. The remaining operation steps of the fifth flushing mode can be the same as those of the fourth flushing mode, and are not described herein.

Of course, the fifth flushing mode may also be triggered manually, and the corresponding button may be triggered by the user to trigger the fifth flushing signal, which is not limited herein.

The water usage of the fifth flush mode was <1.0 liter/flush. The water saving effect is approximately 79% compared to the U.S. standard 4.8 liter/flush (U.S. HET toilet 1.28 gallons) high efficiency toilet. Pressurized flushing is used, which results in a significantly lower water saving, about 1.5 liters/flush, but still results in a water saving of about 69% compared to 4.8 liters/flush.

When the arbitrary flushing mode of this application embodiment starts, all need supercharging device to pressurize for fluid pressure can be between 1.2 and 4.0 bar. The pressurizing means described above may employ a gravity tank 26, an additional pump 28, etc.

When the pressurizing means 26 employs only a gravity tank, the water flow pressure of the gravity tank reaches about 0.15 to 0.2bar. The flushing performance will thus be reduced, but can be compensated to some extent by a higher flushing volume and a larger flushing pipe diameter. The gravity tank 26 may be supplied with tap water or may collect and filter water from a rainwater collection tank. In this case, the

solenoid valves

23a, 23b may also operate without back pressure. The boost function is turned off when the water level is low.

The applicant has studied and proved that the toilet apparatus 100 of the present application has a high water saving effect. Table four shows the calculation of the water saving amount after 2 full flushes and 6 urinations per day for 2 adults (male and female) using the toilet apparatus 100 of the embodiment of the present application, water saving: 82% (No Male flushing mode Water saving: 77%).

* Example (c): one male and one female user per day

As shown in fig. 1, the flushing system 2 of the embodiment of the present application further includes a tank 28 connected to the first spray line 21 and the second spray line 22, and the tank 28 is used for storing a gas-liquid mixture having a certain pressure. The gas-liquid mixture is conveyed to the first spray washing pipeline 21 and the second spray washing pipeline 22 to wash the closestool, so that the washing capacity is improved on one hand, and water can be saved on the other hand.

In addition, a bubble former may be disposed at the first nozzle 210 of the first spray line 21 and the second nozzle 220 of the second spray line 22 to produce a gas-liquid mixture for achieving an optimal cleaning effect.

As shown in fig. 6, the can 28 is made of a pressure-resistant steel body, and has a water inlet and an air inlet (not numbered). An air inlet valve is provided at the air port, and an air pump and a flow-guiding rubber membrane tank are provided, with the help of the air pump, compressed air (1.2 to 4.0bar or higher) can be input into the tank body 28, which has the effect that the flow-guiding rubber membrane tank will expand to the side containing water by the pressurized air and fill the volume with the pressurized air. By providing a booster pump at the water inlet, the booster pump will be activated to generate a higher pressure than the air side to resist the air pressure. Since the air is compressible, one side of the water will compress one side of the air and fill the water into the container at the pressure set by the booster pump.

As shown in fig. 5 and 6, the flushing system of the embodiment of the present application can be integrated into a box D, and an integrated and pre-installable one-piece design, i.e., plug and play, can be implemented, and can be placed on the floor or installed on the wall of a room. This design is easy to install while allowing one flushing system to be used with multiple toilets, e.g. public toilet boxes provided with an integrated plumbing system with universal inlet connectors that can be supplied with water from push buttons, side or top. All electronic components in the cartridge are integrated and wired, so that the integrated flushing system can be connected only to the power supply and also to the operating switch (plug). For the external panel, the wiring is installed in advance, and a control unit (CPU) is also integrated. To ensure a safe space, the can 28 may also be "flat" in that its depth needs to be reduced compared to a spherical or cylindrical container. According to the performance of the booster pump, the booster pump can be arranged outside the box body. The control unit is also connected to a first level sensor 26, a second level sensor 27 and is used to start and stop the booster pump. When the duration is too long and the risk of bacterial growth rises, the control unit can also initiate a clean flush, contributing to improving the sanitary condition of the accumulated water. The flushing system 2 is provided with a plug connector which can be connected with a DC power supply battery for supplying power.

The flushing time and the emptying time of the various flushing modes of the embodiment of the application can be set, and the time setting must be adjustable according to the flushing system, since the flushing process is performed by operating the control valve 23 and the suction device 12 in a time sequence. After selecting this mode, the operator can select the actuation time for each valve/pump after pressing the corresponding actuation button, as shown in table five:
