Description

Technical Field

[0001] The utility model relates to a single-pressure-barrel flushing system and a toilet. Background Art

[0002] Among domestic and foreign bathroom products, existing pressure flush toilets currently generally adopt the dual pressure barrel form, that is, a pressure barrel is placed on each side of the siphon tube in the water tank area behind the ceramic seat body. In order to accommodate such pressure barrels, the width of the matching ceramic seat body needs to be made relatively wide, and the upper and lower widths do not differ much in appearance. At the same time, it appears very bulky, resulting in many limitations in the appearance design of the ceramic seat body, and it is impossible to produce an aesthetically pleasing toilet that meets market demand.

[0003] In addition, the design of two pressure barrels takes up a large space behind the ceramic because of the water inlet valve and flush valve. It is fine for floor-standing toilets, but for wall-mounted toilets with certain height requirements for ceramics: there are many difficulties in production and assembly, resulting in very low efficiency. Moreover, when installing a wall-mounted toilet in a terminal bathroom, it is very inconvenient to connect water and electricity, especially when the water and electricity are concealed behind the toilet. Because the space is too small, the operating space for the angle valve switch is very small, and it is very inconvenient during later maintenance, and the wall may need to be broken, which brings great trouble and living costs to consumers. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present utility model is to provide a single pressure barrel flushing system and a toilet.

[0005] The utility model is realized by the following technical solutions:

[0030] With reference to the drawings in the specification, a flushing system for a single pressure barrel includes: a water inlet valve group 20, the water inlet end of the water inlet valve group is connected to a water source via a water inlet hose 11. The water source referred to here can be municipal water, which is normally connected to the angle valve of the cavity; a first water outlet group 30, the first water outlet group includes a first nozzle 31 and a first water outlet pipe 32 connected thereto, the water inlet end of the first water outlet pipe can be connected to the first water outlet end of the water inlet valve group, and the water outlet end of the first water outlet pipe can be connected to the water inlet end of the first nozzle. In normal use, the first nozzle is an upper water outlet, forming spiral water in the seat body; a pressure barrel 40, the water inlet end of the pressure barrel is connected to the second water outlet end of the water inlet valve group; a second water outlet group 50, the second water outlet group includes a second nozzle 51 and a second water outlet pipe 52 connected thereto, the water inlet end of the second water outlet pipe can be connected to the water outlet end of the pressure barrel, and the water outlet end of the second water outlet pipe can be connected to the water inlet end of the second nozzle. In one use, the first water outlet end of the water inlet valve group is for horizontal water outlet, and the second water outlet end of the water inlet valve group is for vertical water outlet.

[0031] Preferably, a pressure stabilizing valve 10 is provided between the water inlet end of the water inlet valve group and the water inlet hose. The water inlet valve group also includes a vacuum breaker 21. Of course, the water inlet valve group also includes a main component: the water inlet valve.

[0032] Furthermore, the first water outlet group further includes a first electromagnetic valve 33, which is arranged between the first water outlet end of the water inlet valve group and the first water outlet pipe. The first water outlet end of the water inlet valve group is located at the upper end of the water inlet valve group.

[0034] The utility model also discloses another technical feature:

[0035] A toilet comprises the above-mentioned single pressure bucket flushing system.

[0036] The invention also comprises a seat body 60 , a siphon tube 61 is provided in the middle of the rear side of the seat body, and installation spaces 62 are formed in the seat body on both sides of the siphon tube, and the pressure barrel is provided in any installation space.

[0037] Preferably, an upper water outlet 63 is provided on the upper side of the seat body. The first nozzle can be connected to the upper water outlet to form a spiral water flush. A lower water outlet that can cooperate with the siphon is also provided on the lower side of the seat body. The second nozzle can be connected to the lower water outlet to form a straight water flush to discharge waste from the siphon. The upper water outlet is located on the side of the seat body where the pressure barrel is installed. The second water outlet pipe can be connected to the lower water outlet after passing through the installation space on the other side. In other words, the pressure barrel and the upper water outlet are located on the same side of the seat body. After the water inlet end of the second water outlet pipe is connected to the pressure barrel on one side of the seat body, it goes around to the installation space on the other side of the seat body and is connected to the lower water outlet. The second solenoid valve can also be provided in the installation space on the other side. The lower water outlet 64 is located in the middle of the seat body, facing the siphon. This is consistent with the existing technology and will not be elaborated here. At the same time, the water inlet hose can be connected to the water from the installation space on the other side of the seat body and then flow to the installation space on one side of the seat body. Because the installation space on the other side of the seat body is less utilized, it is easy to operate.

[0038] This innovative single-pressure-bucket flush system features a single tank and two solenoid valves, with no additional water tank. The single pressure-bucket flush system is used solely for flushing, spraying water under the toilet to create a siphon. The primary nozzle, powered by tap water, operates with staggered openings controlled by two solenoid valves. This minimizes system costs while ensuring a strong flush and full restoration of the toilet's water seal. Furthermore, the single pressure-bucket flush space is smaller, making it more suitable for wall-mounted toilets. The angle valve can be conveniently concealed behind the ceramic tile. The ceramic tile itself does not need to be modified; it can be directly replaced with a single-tank system.

[0039] The utility model specifically describes: a pressure flushing system for a single pressure barrel, comprising a single-tank pressure barrel, a water inlet valve group with a vacuum breaker, a pressure regulating valve, a first water outlet group, and a second water outlet group; the single-tank pressure barrel is fixedly installed in the installation space at the bottom of either side of the ceramic; the water inlet valve group with a vacuum breaker is the only water inlet channel of the system, and has an anti-siphon function that complies with national standards; the pressure regulating valve is installed at the front end of the water inlet valve group to control the water pressure entering the system within a set range; the first water outlet group comprises a first solenoid valve, a first nozzle and a first water outlet pipe in the middle, the front end of the first solenoid valve is connected to the first water outlet end of the water inlet valve group, and the rear end of the first solenoid valve is connected to the first nozzle through the first water outlet pipe; the second water outlet group comprises a second solenoid valve, a second nozzle and a second water outlet pipe, the front end of the second solenoid valve is connected to the water outlet end of the pressure barrel, and the rear end of the second solenoid valve is connected to the second nozzle. The main features of the matching toilet are: the toilet is a water tankless ceramic toilet, which looks not much different from an ordinary smart toilet; the toilet has a siphon tube, as well as an upper water spray outlet and a lower water spray outlet; the toilet can be a floor-standing siphon toilet or a wall-mounted siphon toilet, especially the wall-mounted siphon toilet is more advantageous when matched with the main body system, and can effectively utilize a single pressure barrel to occupy a small installation space.

[0040] In the utility model: the water in the single pressure barrel is only supplied to the lower outlet of the toilet; the upper water outlet is directly derived from the impact of tap water; the water inlet valve group with a vacuum breaker is the main water inlet, ensuring that the system meets the overall requirements of the national standard for anti-siphonage; the pressure-stabilizing valve installed in front of the water inlet valve group not only ensures that the lower jet water outlet has sufficient force and high pressure without noise, but also the water flow of the first water outlet pipe passes through the pressure-stabilizing valve, ensuring that the upper water outlet will not splash due to the high water pressure of tap water; two solenoid valves control the upper and lower water outlets respectively, and the time of the upper and lower water outlets is controlled by programming the circuit board inside the cover plate; it is ensured that any ceramic water seal is fully restored to meet the stable needs of mass production.

[0041] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments.
