[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0026] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0027] In order to solve the problem of high cost and poor economic benefit of mass production of special-shaped water tanks in the prior art, the utility model provides a toilet water tank assembly and a toilet.

[0028] like Figures 1 to 6 A toilet water tank assembly shown includes multiple water tanks 10 and connecting pipes 20. The water tanks 10 are arranged in sequence along the circumference of the toilet, and at least one water tank 10 has an arc-shaped structure, and the water tanks 10 form a accommodating area; the connecting pipe 20 is located between two adjacent water tanks 10, and the two adjacent water tanks 10 are connected to each other through the connecting pipe 20.

[0029] In this embodiment, a plurality of water tanks 10 are provided, and the water tanks 10 are arranged along the circumference of the toilet. The water tanks 10 are connected in sequence through connecting pipes 20. In this way, the water tank is no longer an integral component surrounding the toilet, but is composed of a plurality of small water tanks 10. In this way, when designing the shape of the water tank 10, the water tank 10 can be designed into a regular shape, and the special-shaped structure in the ceramic can be filled with a plurality of regular-shaped water tanks 10. In this way, on the one hand, it can meet the design requirements of special-shaped water tanks, and at the same time, it can make the shape of each water tank 10 regular, thereby facilitating the use of processing methods such as injection molding, which is conducive to mass production and improves production efficiency. It can also reduce the cost of mass production and achieve higher economic benefits, achieving multiple goals at one stroke.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, all water tanks 10 cooperate to form a large interconnected box body, which includes a U-shaped portion and an input portion. The U-shaped portion and the input portion are each specifically formed by several water tanks 10 and can be arranged accordingly as needed. For example, the U-shaped portion can be formed by one water tank 10, or by connecting two J-shaped water tanks 10, or by adding a small U-shaped water tank 10 to two rectangular water tanks 10, etc. The shape of the U-shaped portion can match the shape of the toilet. The inner side of the U-shaped portion forms a storage area, which can be used to install other components of the toilet or can be left empty. The input portion is connected to the end of the U-shaped portion, and the input portion and the end of the U-shaped portion are connected by a connecting pipe 20. An opening can be provided on the top surface of the input portion to facilitate water filling into the water tank 10 and observation and maintenance, etc., thereby realizing the water storage function of the water tank 10.

[0031] In this embodiment, taking into account the utilization of the irregular space, this embodiment adopts a U-shaped portion with different lengths at both ends. The length here refers to the distance between the end of the U-shaped portion and the middle bend, that is, the lengths of the two straight sections of the U-shaped portion are different, so that the U-shaped portion is formed in a form where the two ends are not flush. Such a U-shaped portion can better conform to the form of the irregular space, thereby meeting the design requirements, and the input part is located at the end of the U-shaped part with a longer length, so that the input part can extend to the rear position of the toilet, thereby achieving coordination with components such as the water inlet pipe, and also conforming to the user's usage habits.

[0032] The toilet water tank assembly of this embodiment is mainly formed by three water tanks 10. Specifically, all water tanks 10 include a first water tank 11, a second water tank 12 and a third water tank 13, wherein the first water tank 11 serves as the aforementioned input portion, and the second water tank 12 and the third water tank 13 cooperate to form the aforementioned U-shaped portion. Therefore, the top of the first water tank 11 is open and a water inlet can be provided on its side to achieve the effect of filling water into all water tanks 10; the second water tank 12 is connected to the first water tank 11 and communicates with it through the connecting pipe 20. The third water tank 13 is connected to the second water tank 12 and communicates with it through the connecting pipe 20. The end of the second water tank 12 away from the first water tank 11 and the end of the third water tank 13 close to the second water tank 12 both have an arc-shaped structure. The arc-shaped structure of the second water tank 12 and the arc-shaped structure of the third water tank 13 are bent toward each other, so that the second water tank 12 and the third water tank 13 both form a J-shaped structure. The J-shaped structures are bent in the direction of approaching each other, so that the two J-shaped structures are docked and matched to form a U-shaped portion. In this way, the integrated large box body formed by the cooperation between the water tanks 10 can meet the design requirements of special-shaped spaces, which is conducive to increasing the space size of the water tank 10 and increasing the water output.

[0033] It should be noted that the specific shape and arrangement of the water tanks 10 described above in this embodiment are not the only setting method, but a design form given only based on an actual situation. When the shape of the toilet and other requirements change, the specific shape and arrangement of the water tanks 10 can also be adjusted accordingly as needed. It is only necessary to ensure that the water tanks 10 are connected in sequence through the connecting pipes 20 so that their internal spaces form a whole, and the water tanks 10 adopt regular shapes as much as possible for easy processing.

[0034] like Figures 3 to 6 As shown, in this embodiment, the connecting pipe 20 includes a first pipe body 21 and a second pipe body 22, and the first pipe body 21 and the second pipe body 22 are respectively located between two adjacent water tanks 10, and the diameters of the first pipe body 21 and the second pipe body 22 are different. In this embodiment, the diameter of the first pipe body 21 is smaller than the diameter of the second pipe body 22. In this way, when docking, at least a portion of the first pipe body 21 can extend into the second pipe body 22, so that the first pipe body 21 and the second pipe body 22 are docked and connected, and then the two water tanks 10 are docked and connected, so that the water in one water tank 10 can enter the other water tank 10 through the connecting pipe 20.

[0035] For ease of processing, the first tube body 21 and the second tube body 22 of this embodiment are both straight tubes and are arranged in the middle position of the side of the water tank 10. Of course, the specific structural forms of the first tube body 21 and the second tube body 22 can also be adjusted accordingly as needed. At the same time, the specific structural form of the connecting pipeline 20 can also be adjusted, such as setting more sections of the tube body.

[0036] To ensure the reliability of the docking connection between the first tube body 21 and the second tube body 22, the toilet tank assembly of this embodiment further includes a locking structure 30. The locking structure 30 is located between the first tube body 21 and the second tube body 22. When the first tube body 21 extends into the second tube body 22, it is docked and locked by the locking structure 30. In this way, the locking structure 30 ensures the locking fit of the first tube body 21 and the second tube body 22 after docking, preventing the first tube body 21 and the second tube body 22 from falling off, ensuring reliability and extending service life.

[0037] like Figure 4 and Figure 6 As shown, the locking structure 30 of this embodiment adopts the form of a snap-fit connection. Specifically, the locking structure 30 includes a buckle 31 and a boss 32. The buckle 31 is located at the outer peripheral side of the first tube body 21 and faces the second tube body 22. A part of the buckle 31 can be deformed, and the boss 32 is located at the outer peripheral side of the second tube body 22 and protrudes from the outer peripheral side of the second tube body 22. The boss 32 forms a step surface at one end away from the first tube body 21. In this way, when the first tube body 21 extends into the second tube body 22, the protrusion at the end of the buckle 31 abuts against the boss 32, and the buckle 31 is squeezed by the boss 32 to be locked. The first tube body 21 is deformed, the protrusion passes over the boss 32, and the first tube body 21 continues to extend into the second tube body 22 until the first tube body 21 is extended into place and the protrusion completely passes over the boss 32. The protrusion is now in contact with the step surface, and the contact of the step surface prevents the buckle 31 from passing over the boss 32 when no external force is applied. The buckle 31 remains engaged with the step surface, thereby preventing the first tube body 21 from separating from the second tube body 22. In this way, the first tube body 21 cannot withdraw from the second tube body 22 without external force, so that the first tube body 21 and the second tube body 22 maintain a docking state, thereby ensuring the reliability of the communication between the two water tanks 10.

[0038] Optionally, the number of buckles 31 can be set as needed, and one or more buckles can be set. When one buckle is set, the buckle 31 can extend along the circumference of the first tube body 21 to ensure the snap-on effect. In this embodiment, there are multiple buckles 31, and each buckle 31 is arranged at intervals along the circumference of the first tube body 21. In this embodiment, the buckles 31 are preferably arranged at equal intervals along the circumference of the first tube body 21 to ensure the balance and uniformity of the clamping force of the buckles 31. Correspondingly, the boss 32 is continuously arranged along the circumference of the second tube body 22. In this way, there is no need to consider the relative position between the buckle 31 and the boss 32 during docking. It is only necessary to extend the first tube body 21 into the second tube body 22 to make the buckle 31 and the boss 32 snap-on fit together. The assembly is simpler and faster, and since the first tube body 21 and the second tube body 22 of this embodiment are both round tubes, the continuously arranged bosses 32 allow the buckle 31 to change its position along the annular step surface after being engaged with the step surface, so that the first tube body 21 and the second tube body 22 are relatively rotatable at this time, so that the state of the two water tanks 10 can be adjusted within a certain range even after docking, so that the connected water tanks 10 can be rotated according to the angle of the special-shaped space to achieve the maximum placement space.

[0039] In this embodiment, a pressing area is provided at the end of the clip 31 away from the second tube body 22, that is, the end of the clip 31 away from the protrusion. The pressing area can be provided with ribs to facilitate force application. The deformation center of the clip 31, that is, the connection with the first tube body 21, is located between the two ends. In this way, when the first tube body 21 and the second tube body 22 need to be disassembled, it is only necessary to press the pressing area to deform the clip 31 and lift the protrusion, so that the protrusion at the end of the clip 31 is released from the step surface, and the first tube body 21 can be separated from the second tube body 22.

[0040] Of course, in addition to the clamping method, the above-mentioned docking structure can also adopt other settings to achieve the locking fit between the first tube body 21 and the second tube body 22. For example, the locking structure 30 adopts a clamp locking method, which includes two semicircular first clamps and second clamps. The second tube body 22 can have a certain flexibility. When the first tube body 21 is extended into the second tube body 22 and is in place, two clamps are sleeved on the outside of the second tube body 22, and then the two clamps are locked by bolts. The two clamps clamp the second tube body 22 so that the second tube body 22 is deformed. The second tube body 22 is clamped on the outside of the first tube body 21 under the action of the clamps, thereby achieving locking between the first tube body 21 and the second tube body 22.

[0041] In this embodiment, the toilet tank assembly further includes a seal 40. When the first tube 21 and the second tube 22 are connected, the seal 40 is located between the first tube 21 and the second tube 22, and seals the gap between the first tube 21 and the second tube 22. The seal 40 of this embodiment is a sealing ring, and the number of seals 40 can be set as needed, and one or more seals can be provided. In this embodiment, two sealing rings are provided. Two shallow annular grooves are defined on the outer peripheral side of the first tube 21. The two sealing rings are respectively sleeved in the two annular grooves and protrude from the outer peripheral side of the first tube 21. When the first tube 21 is inserted into the second tube 22, the sealing ring also extends into the second tube 22 and tightly fits against the inner wall of the second tube 22, thereby enabling the sealing ring to seal the gap between the outer peripheral side of the first tube 21 and the inner wall of the second tube 22, thereby ensuring sealing performance.

[0042] It should be noted that, in order to facilitate the display of the docking structure, Figures 3 to 6 The shape of the water tank 10 is simplified in the figure, and the actual shape may not be the same as shown in the figure.

[0043] It should be noted that, in the above embodiments, a plurality refers to at least two.
