[0039] Please see Figures 1 to 7 The present invention proposes a toilet 100, including a seat 10, a water tank 30, and a flushing device 40. The seat 10 forms a toilet bowl 11 and an installation cavity 12, which are separated. The wall of the toilet bowl 11 forms a main flush port 111. A sewage pipe 14 is also formed in the installation cavity 12. One end of the sewage pipe 14 is connected to the toilet bowl 11 and is arranged opposite to the main flush port 111. The water tank 30 is installed in the installation cavity 12 and is arranged around the toilet bowl 11. The flushing device 40 includes a water pump 41 and a main flush pipe 42. The water pump 41 is located in the installation cavity 12 and is located on one side of the extension direction of the water tank 30. The water pump 41's pumping end is connected to the water tank 30. One end of the main flush pipe 42 is connected to the water pump 41's drain end, and the other end of the main flush pipe 42 is connected to the main flush port 111.

[0040] The toilet seat 10 is fixed to the bracket 51, which is fixed to the wall. The seat 10 can be made of ceramic or metal, depending on the specific situation. The water tank 30 is generally made of plastic, which has low density, is not easy to corrode, has high strength, is sturdy and durable, and is easy to process. The bottom surface of the seat 10 is provided with an opening 17 to facilitate the installation of the water tank 30 and other components into the installation cavity 12.

[0041] The aforementioned water tank 30 can surround the toilet bowl 11 horizontally, vertically, or both. For example, the water tank 30 can surround the left and front sides of the toilet bowl 11 horizontally. Furthermore, the angle between the projections of the two ends of the water tank 30 to the center of the toilet bowl 11 on the horizontal plane can be set within the range of 145 degrees to 270 degrees. Alternatively, the water tank 30 can surround the toilet bowl 11 vertically, and the angle between the projections of the two ends of the water tank 30 to the center of the toilet bowl 11 on a plane perpendicular to the front-back horizontal line can be set within the range of 145 degrees to 270 degrees. The direction and angle of the water tank 30's surroundings are set according to specific circumstances and are not limited here.

[0042] The aforementioned water pump 41 is located on one side of the water tank 30 in the extending direction, which is the same as the circumferential direction. The water pump 41 can be installed on the cavity wall of the mounting cavity 12 or on the water tank 30. The main flushing pipe 42 can be connected from the inside of the water tank 30 to the main flushing port 111, or a clearance passage can be opened on the front side of the water tank 30, through the clearance passage from the outside of the water tank 30 to the main flushing port 111. There are many other specific embodiments of the water pump 41 and the main flushing pipe 42, which will not be listed here.

[0043] The present invention provides a solution by arranging the water tank 30 around the toilet bowl 11 and placing the water pump 41 inside the mounting cavity 12 and in the surrounding direction of the water tank 30. This results in a higher space utilization rate for the mounting cavity 12 of the seat body 10, a more reasonable and compact spatial arrangement of the water pump 41 and the water tank 30, and a higher volume of the water tank 30.

[0044] Furthermore, in some embodiments of this utility model, the mounting cavity 12 includes a first side cavity 121, a second side cavity 122, and a front cavity 123. The first side cavity 121 and the second side cavity 122 are distributed on the left and right sides of the toilet bowl 11, and the front cavity 123 is located on the front side of the toilet bowl 11. The water tank 30 includes a side tank portion 31 and a front tank portion 32. The side tank portion 31 is located in the first side cavity 121, the front tank portion 32 is located in the front cavity 123, and the water pump 41 is located in the second side cavity 122. With this arrangement, the space arrangement inside the mounting cavity 12 is more reasonable, which can effectively increase the volume of the water tank 30 and ensure sufficient installation space for the water pump 41 and other components in the toilet.

[0045] Furthermore, in some embodiments of this utility model, the toilet 100 also includes a water inlet valve 60 and a connecting pipe 70. The water inlet valve 60 is located in the second side cavity 122 and is spaced apart from the water pump 41. The water inlet end of the water inlet valve 60 is connected to a tap water pipe, one end of the connecting pipe 70 is connected to the water outlet end of the water inlet valve 60, and the other end of the connecting pipe 70 is connected to the side chamber 31 of the water tank 30. With the above solution, during assembly, the water inlet valve 60 and the water tank 30 do not interfere with each other, effectively utilizing the space of the second side cavity 122.

[0046] Furthermore, in some embodiments of this utility model, the sewage pipe 14 is arranged in an arc shape, with an archway 15 formed on its lower side. The connecting pipe 70 passes through the archway 15 and connects with the side box 31. In this way, the sewage pipe 14 is inverted U-shaped, which can achieve a siphon effect and make full use of the space of the archway 15 below the sewage pipe 14, resulting in a more reasonable spatial arrangement.

[0047] In some embodiments of this utility model, the main flush port 111 is located at the bottom of the front wall of the toilet bowl 11, and a first clearance channel 321 is correspondingly provided at the bottom of the front tank 32 to allow the main flush pipe 42 to pass through. With this arrangement, the main flush pipe 42 can extend from the front of the water tank to the first clearance channel 321 and connect to the main flush port 111 through the first clearance channel 321, without having to bypass the water tank 30 from the top or bottom to connect the main flush port 111. This results in a shorter pipe and less space occupied, and also avoids excessive bending angles in the pipe that could affect the pipe structure. In addition, the water tank 30 has more space to accommodate the pipe, which is beneficial for increasing its capacity.

[0048] Furthermore, in some embodiments of this utility model, a second clearance channel 322 is recessed in the front sidewall of the main body, and the second clearance channel 322 connects to the first clearance channel 321. With this arrangement, the second clearance channel 322 can be used for the main flush pipe 42 to be installed, so that there does not need to leave a large gap between the water tank 30 and the toilet seat 10 for the main flush pipe 42 to pass through, which helps to increase the space ratio of the water tank 30 in the installation cavity 12, thereby increasing the capacity of the liquid storage cavity.

[0049] To facilitate the installation of the flushing device 40 into the mounting cavity 12, in some embodiments of this utility model, the bottom surface of the toilet seat 10 is provided with an opening 17, and the first clearance channel 321 connects to the opening 17. With this arrangement, when assembling the flushing device 40, the water pump 41 in the flushing device 40 can be installed into the mounting cavity 12 through the opening 17. When installing the main flush pipe 42, the assembler can reach their hand through the opening 17 into the first clearance channel 321 to connect the main flush pipe 42 to the main flush port 111.

[0050] In some embodiments of this utility model, the water tank 30 further includes a bottom tank portion 33, which is located below the toilet bowl 11. One side of the bottom tank portion 33 is connected to and communicates with the side tank portion 31, and the other side of the bottom tank portion 33 extends to the bottom of the second side cavity 122 and communicates with the water pump 41. In this way, the water tank 30 surrounds the toilet bowl 11 in both the horizontal and vertical circumferences, allowing for a larger volume of the water tank 30 and further improving the space utilization within the mounting cavity 12.

[0051] In some embodiments of this utility model, a connecting port 13 is provided on the top surface of the bottom tank 33 away from the side tank 31. The connecting port 13 is connected to the water pump 41. With this arrangement, the bottom tank can store a certain amount of water. On the one hand, this makes the overall center of gravity of the water tank 30 lower and more stable. On the other hand, it avoids the problem of the water in the water tank 30 being pumped dry by the water pump 41, which would cause a lot of noise.

[0052] In order to improve the structural strength of the water tank 30, in some embodiments of the present invention, the front side of the bottom tank 33 is connected and communicates with the end of the front tank 32 near the second side cavity 122.

[0053] The water tank 30 and the seat 10 are generally connected by screws, but snap-fit ​​or adhesive connections are also possible. In some embodiments of this invention, the toilet 100 further includes a connecting part 80, with its two ends connected to the left and right sides of the bottom of the seat 10, and its middle part connected to the bottom surface of the base 33. This arrangement allows the connecting part 80 to stably support the water tank 30, while the cavity wall of the mounting cavity 12 restricts the water tank 30 from tilting forward or backward. The fixing method is simple and effective, and disassembly and assembly are relatively convenient.

[0054] The connecting part 80 can be integrally formed with the bottom box or it can be detachably connected to the bottom box. There are various ways to detach it. In some embodiments of this utility model, the bottom wall of the bottom box has a slot that extends through the left and right directions. The connecting part 80 is a connecting plate that passes through the slot and is fixed to the base 10 at both ends.

[0055] In some embodiments of this utility model, the water pump 41 is installed on the top surface of the bottom box 33. In conjunction with the above scheme, when assembling the water tank 30 and the flushing device 40, the water pump 41 and the main flushing pipe 42 can be pre-installed on the water tank 30, and then the whole assembly can be installed into the mounting cavity 12. Finally, the main flushing pipe 42 and the main flushing port 111 are connected through the first clearance channel 321, which makes the assembly convenient and quick.

[0056] Furthermore, in some embodiments of this utility model, recessed clearance notches 331 are formed on the opposite sides of the bottom tank 33 corresponding to the positions of the connecting portions 80, and mounting protrusions 16 are provided on the opposite sides of the mounting cavity 12. Each mounting protrusion 16 engages with a clearance notch 331, and the end of the connecting portion 80 is connected to the bottom surface of the mounting protrusion 16. This arrangement allows the mounting protrusion 16 to restrict the back-and-forth swinging of the water tank 30, facilitating alignment during assembly.

[0057] Furthermore, in some embodiments of this utility model, the bottom surface of the base box 33 is recessed to form an assembly groove 332. The bottom wall of the assembly groove 332 is provided with a threaded hole, and the connecting part 80 is correspondingly provided with a through hole 81. The connecting part 80 is assembled in the assembly groove 332, and the screw-in component passes through the through hole 81 and is assembled in the threaded hole. In this way, after the water tank 30 is assembled into the mounting cavity 12, the connecting part 80 is positioned in the assembly groove 332, and the assembler only needs to align the threaded hole in the extending direction of the assembly groove 332, which further facilitates the installation.

[0058] In some embodiments of this utility model, the connecting part 80 is positioned close to the center of gravity of the water tank 30, which makes the structure more stable.

[0059] In some embodiments of this utility model, the toilet 100 also includes a brush ring pipe 43, one end of which is connected to the drain outlet 412 of the water pump 41, and the other end of which is connected to the top of the toilet bowl 11.

[0060] In some embodiments of this utility model, the toilet 100 further includes a control component, an electrically controlled three-way valve 91, and a brush ring pipe 43. The control component is installed on the seat 10 and electrically connected to the water pump 41 and the electrically controlled three-way valve 91. The brush ring pipe 43, the main flush pipe 42, and the water pump 41 are respectively connected to the three valve ports of the electrically controlled three-way valve 91. The end of the brush ring pipe 43 away from the electrically controlled three-way valve 91 is connected to the top of the toilet bowl 11. The control component can be a switch, or it can be composed of a microcontroller or a PWM controller, etc. The control component is used to control the working state of the water pump 41, thereby realizing flushing. This control component is generally installed on the outside of the seat 10, behind the toilet lid 50, for easy access by the user.

[0061] This utility model also proposes a method for flushing using the above-mentioned toilet 100, including the following steps:

[0062] S1. Send a brush ring signal to the electric three-way valve 91 and a start signal to the water pump 41 respectively. The valve of the electric three-way valve 91 connected to the brush ring pipe 43 is opened, and the water pump 41 draws water from the water tank 30 and delivers it to the electric three-way valve 91.

[0063] S2. After the first set time has elapsed, a main flush signal is sent to the electrically controlled three-way valve 91, and the valve of the electrically controlled three-way valve 91 connected to the main flush pipe 42 is opened.

[0064] S3. After the second set time has elapsed, a main flush stop signal is sent to the electrically controlled three-way valve 91, and the valve of the electrically controlled three-way valve 91 connected to the main flush pipe 42 is closed.

[0065] S4. After the third set time has elapsed, a brush ring stop signal is sent to the electrically controlled three-way valve 91, and the valve connecting the electrically controlled three-way valve 91 to the brush ring pipeline 43 is closed.

[0066] The aforementioned control component is equipped with a readable storage medium storing a program containing the method. Through this method, when the toilet is flushed, the brush ring is brushed first, and then the water is flushed. After the sewage in the toilet bowl 11 is siphoned away, water continues to enter the brush ring pipe 43, so that some water is retained in the toilet bowl 11 for the user's next use.

[0067] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
