[0057] In the embodiments of the present invention, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted.

[0058] like Figure 1 、 Figure 2 as well as Figure 3 As shown, this embodiment provides a toilet, including a toilet seat 200, a water tank 300, a drain valve 400, a drain valve base 500 and a toilet secondary flush flow channel assembly 100.

[0059] Combine Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 The toilet seat 200 includes a toilet bowl 201 and a main flush pipe section 202 connected to the toilet bowl 201. A water tank 300 is disposed within the toilet seat 200. A drain valve 400 is disposed within the water tank 300 and is connected to a seal 401. A drain valve base 500 is connected to the bottom wall of the water tank 300 and defines a cavity 501. The drain valve 400 is used to drive the seal 401 to move, thereby blocking or opening the upper end of the cavity 501. One end of the toilet secondary flush flow channel assembly 100 is connected to the lower end of the drain valve base 500 and is connected to the cavity 501. The other end is connected to the main flush pipe section 202, allowing water to flow through the main flush pipe section 202 toward the toilet bowl 201.

[0060] Exemplarily, the sealing member 401 is a sealing gasket, specifically a sealing rubber gasket, which ensures sealing contact with the drain valve base 500 to block the upper port of the cavity 501 of the drain valve base 500 .

[0061] like Figure 4 and Figure 5, shows a schematic structural diagram of a toilet auxiliary flush flow channel assembly 100 provided in this embodiment. The toilet auxiliary flush flow channel assembly 100 includes a first pipe 1, a second pipe 2, and a third pipe 3, which are sequentially connected and separately arranged. The water inlet end of the first pipe 1 is configured to be blockably connected to the toilet water tank 300, and the water outlet end of the third pipe 3 is configured to be connected to the toilet bowl 201. Specifically, the water inlet end of the first pipe 1 is connected to the lower end of the drain valve base 500. When the seal 401 blocks the drain valve base 500, the water tank 300 and the first pipe 1 are disconnected, and the water in the water tank 300 cannot be introduced into the first pipe 1 through the cavity 501 of the drain valve base 500. When the seal 401 moves under the drive of the drain valve 400 to open the drain valve base 500, the water tank 300 and the first pipe 1 are connected, and the water in the water tank 300 is instantly introduced into the first pipe 1 through the cavity 501 of the drain valve base 500. The third pipe 3 is connected to the toilet bowl 201 through the main flush pipe section 202. The first pipe 1 and the third pipe 3 are at least partially bent to facilitate the connection between the water tank 300 and the toilet bowl 201.

[0062] Furthermore, the materials of the first pipe 1, the second pipe 2, and the third pipe 3 are different from each other, or at least the materials of the first pipe 1, the second pipe 2, and the third pipe 3 are the same. Specifically, the materials of the first pipe 1, the second pipe 2, and the third pipe 3 can be the same, such as all made of plastic or rubber; or the materials of the first pipe 1, the second pipe 2, and the third pipe 3 can be different from each other; or the first pipe 1 and the second pipe 2 can be made of the same material, while the third pipe 3 can be made of a different material from the first pipe 1 and the second pipe 2; or the first pipe 1 and the third pipe 3 can be made of the same material, while the second pipe 2 can be made of a different material from the first pipe 1 and the second pipe 2. The materials can be selected according to specific needs, and there is no specific limitation on the materials herein.

[0063] In this embodiment, the first pipe 1 is a rubber pipe, the second pipe 2 is a plastic pipe, and the third pipe 3 is a rubber pipe. This is more cost-effective than a ceramic flow channel assembly, with costs reduced by 30%. Furthermore, the first pipe 1 and the third pipe 3 at both ends are curved pipes, so they are easy to shape using rubber materials. Because they have a certain elastic deformation capacity, they facilitate connection with the second pipe 2, the drain valve base 500, and the main flush pipe section 202, while also providing a certain vibration absorption effect. The plastic second pipe 2 in the middle gives the entire secondary flush flow channel assembly high strength and deformation resistance.

[0064] Exemplarily, the second pipe 2 is made of PVC (polyvinyl chloride) pipe.

[0065] The toilet auxiliary flush channel assembly 100 provided in an embodiment of the present application has one end in blockable communication with the toilet water tank 300 via a first conduit 1, and the other end in communication with the toilet bowl 201 via a third conduit 3. When the first conduit 1 is connected to the water tank 300, water in the water tank 300 is flushed into the toilet bowl 201 through the auxiliary flush channel assembly, achieving flushing and cleaning. By separating the auxiliary flush channel assembly into the independent first conduit 1, second conduit 2, and third conduit 3, the three components can be manufactured separately and then assembled and connected together later. This reduces production complexity and improves efficiency, saving production costs compared to solutions that manufacture auxiliary flush channel assemblies from ceramic materials. Furthermore, the first conduit 1 and third conduit 3 are at least partially curved, diverting the flow path and facilitating connection between the water tank 300 and the toilet bowl 201. The separate first, second, and third conduits 1, 2, and 3 allow for adaptable production with larger inner diameters. This reduces water discharge noise compared to smaller inner diameter braided tube structures and improves the user experience.

[0066] See also Figure 5 In this embodiment, the first pipe 1 includes a first curved pipe body 11, and a first pipe joint 12 and a second pipe joint 13 connected to the ends of the first curved pipe body 11, respectively. The axis of the first pipe joint 12 is vertically arranged and is configured to connect to the toilet's drain valve base 500. The second pipe joint 13 is connected to the second pipe 2 and is arranged at an acute angle relative to the horizontal plane. Specifically, the first pipe joint 12 is sleeved and inserted outside the drain valve base 500, and the second pipe joint 13 is sleeved and inserted at one end of the second pipe 2. Because the first pipe joint 12 is vertically arranged, the drain valve base 500 connected to it is also vertically arranged, and its cavity 501 is also vertically arranged. Therefore, when the drain valve 400 is opened, the water in the water tank 300 can flow downstream under the action of gravity, reducing water flow resistance and increasing flushing speed.

[0067] Of course, in other embodiments, the axis of the first pipe joint 12 may also be set at an acute angle to the vertical direction, for example, extending downwardly relative to the drain valve base 500, as long as the water can flow smoothly downward.

[0068] The second pipe 2 is a straight pipe, which is easy to prepare, reduces water flow resistance, and speeds up the flushing speed of the toilet.

[0069] The third pipe 3 includes a second curved pipe body 31 and a third pipe joint 32 and a fourth pipe joint 33 connected to the ends of the second curved pipe body 31, respectively. The third pipe joint 32 is connected to the second pipe 2, and the fourth pipe joint 33 is configured to connect to the main flush pipe section 202 of the toilet bowl 201. Specifically, the third pipe joint 32 is sleeved and plugged onto the other end of the second pipe 2, and the fourth pipe joint 33 is sleeved and plugged onto the main flush pipe section 202 to achieve communication with the toilet bowl 201.

[0070] Further, see Figure 5 The toilet secondary flush flow channel assembly 100 also includes a first clamp 41, a second clamp 42, a third clamp 43, and a fourth clamp 44. The first clamp 41 is tightened between the first pipe joint 12 and the drain valve base 500; the second clamp 42 is tightened between the second pipe joint 13 and the second pipe 2; the third clamp 43 is tightened between the third pipe joint 32 and the second pipe 2; and the fourth clamp 44 is tightened between the fourth pipe joint 33 and the main flush pipe section 202. In other words, the rubber-made first pipe 1 and third pipe 3 are each tightened to the drain valve base 500, the second pipe 2, or the main flushing hole 203 by corresponding clamps. Taking the fourth pipe joint 33 as an example, the fourth clamp 44 is mounted on the outside of the fourth pipe joint 33. Because the rubber material has a certain degree of deformation, tightening the fourth clamp 44 can firmly press the fourth pipe joint 33 to the outer wall of the main flush pipe section 202, making the connection convenient and fast while ensuring stability. Two fourth clamps 44 are exemplarily provided outside the fourth pipe joint 33 to effectively improve the connection strength and prevent the third pipe 3 from being disconnected from the main flushing pipe section 202 due to excessive water pressure during flushing. The number of the other clamps can be set according to needs.

[0071] In this embodiment, see Figure 3 The cross-sectional area of the main flushing pipe section 202 gradually increases in the direction away from the toilet bowl 201. That is, the main flushing pipe section 202 has a slope toward the toilet bowl 201. When the fourth pipe joint 33 is clamped to the outside of the main flushing pipe section 202 by the fourth clamp 44, it is not easy to fall off, thereby increasing the stability and reliability of the connection between the third pipe 3 and the main flushing pipe section 202.

[0072] In this embodiment, see Figure 6 The curvature radius R of the first curved pipe body 11 is 35 mm to 55 mm. Within this size range, the first curved pipe body 11 can ensure that the water flow is introduced into the second pipe 2 while increasing the water flow speed and reducing the water flow resistance. Furthermore, the curvature radius R of the first curved pipe body 11 is 42 mm to 44 mm.

[0073] In this embodiment, see Figure 6The inclination angle α of the second pipe 2 relative to the horizontal plane is 5° to 15°, and the first pipe 1 is higher than the third pipe 3, that is, along the direction from the first pipe 1 to the third pipe 3, the second pipe 2 gradually tilts downward. The second pipe 2 with an inclination angle of 5° to 15° enables the second pipe 2 to have a certain drainage capacity, and the water flow can flow smoothly to the third pipe 3 through the first pipe 1 under the action of gravity. Moreover, the inclination angle will not be too large to cause excessive vertical space occupation, which is convenient for reducing the height size of the entire toilet and making the internal structure of the toilet more compact and reasonable. Furthermore, the second elbow body 31 bends and extends in the horizontal direction to achieve connection with the main flush pipe section 202. The overall slope of the toilet secondary flush flow channel assembly 100 is between 5° and 15°. While ensuring smooth drainage, it can reduce the space occupied in the height direction and the design is more reasonable.

[0074] In this embodiment, see Figure 7 The inner diameter of the second elbow body 31 gradually decreases along the water flow direction, thereby increasing the pressure of the water sprayed through the third pipe 3 and achieving pressurized water discharge. Figure 3 The inner hole of the main flushing pipe section 202 is the main flushing hole 203, and its inner diameter gradually decreases in the direction close to the toilet bowl 201, further increasing the pressure, thereby increasing the flushing water pressure and increasing the flushing force.

[0075] For example, in this embodiment, the inner diameter of the second pipe 2 is 40 mm. The inner diameter D1 of the second elbow body 31 of the third pipe 3 is 40 mm at the large end to facilitate docking with the second pipe 2, and the inner diameter D2 of the small end is 30 mm, effectively increasing water pressure. The water inlet diameter of the main flushing hole 203 is 30 mm, and the water outlet diameter is 26 mm. This ensures flushing force without causing the flushing noise that would be caused by a smaller inner diameter of the main flushing hole 203.

[0076] Alternatively, see Figure 5 and Figure 7 The inner walls at both ends of the first pipe 1 are provided with first anti-slip protrusions 14; and / or, the outer walls at both ends of the second pipe 2 are provided with second anti-slip protrusions; and / or, the inner walls at both ends of the third pipe 3 are provided with third anti-slip protrusions 34, which can increase the friction between adjacent pipes after insertion and have a better anti-slip effect.

[0077] The toilet provided in this embodiment also includes a flushing assist component 600, such as Figure 2 、 Figure 4 as well as Figure 8 As shown, the flushing assembly 600 includes a flushing pump 601 and a flushing nozzle 602. The flushing pump 601 is arranged in the water tank 300, and the drain valve base 500 is provided with a flushing hole 502 (see Figure 9), one end of the nozzle is connected to the water outlet of the booster pump 601 through the booster water hole 502, and the other end extends to the first pipe 1, in the same direction as the extension of the first pipe 1. Specifically, the water outlet of the booster pump 601 is connected to the booster water pipe 603, and the booster water pipe 603 is connected to the booster nozzle 602 through the booster water hole 502. The water inlet of the booster pump 601 is located in the water tank 300. When started, it can pump water in the water tank 300 into the booster nozzle 602 through the booster water pipe 603, thereby flushing out a water flow with a higher flow rate, driving the water flow in the toilet secondary flush flow channel assembly 100 to flow rapidly, thereby increasing the potential energy of the secondary flush water flow. The secondary flush water flow is then sprayed into the toilet bowl 201 through the main flush pipe section 202, causing the toilet to produce a siphon.

[0078] like Figure 9 As shown, a mounting column 503 is provided on the drain valve base 500, and the inner hole of the mounting column 503 is the flushing water hole 502. A part of the mounting column 503 is located in the cavity 501 to be plugged into the flushing nozzle 602, and the other part extends to the outside to be connected to the flushing water pipe 603.

[0079] See also Figure 1 The toilet also includes a water inlet valve 700, which is connected to an external pipeline and can be controlled to store water in the water tank 300.

[0080] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
