[0033] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following will be used to explain the embodiments of the utility model in detail in conjunction with the drawings.It should be explained that, in the case without conflict, the embodiments in the application and the features in the embodiments can be combined with each other at will.

[0034] The embodiments of the application provide a kind of water tank for closestool, as shown in Figures 1-8 ​​​​As shown, the water tank comprises a water tank body 1, which is provided with a water outlet 12 configured to connect to the water inlet end of the water pump; the water tank body 1 is further provided with a vortex preventing structure for preventing vortex, which comprises a baffle located above the water outlet 12 and below the use liquid level of the water tank, and a guide channel 14 is formed below the baffle and in communication with the water outlet 12, so that the water in the water tank body 1 flows out of the water outlet 12 through the guide channel 14. Wherein, the use liquid level refers to the liquid level of the water tank when it is applied to the closestool and the water pump is in the non-draining state.

[0035] The water tank body 1 can be further provided with a vent 11 to ventilate the inside of the water tank with the outside when the water pump is pumping water.

[0036] In the technical scheme provided by the embodiment of the present application, the vortex preventing structure with the baffle can prevent the suction force of the water outlet 12 from directly facing the liquid level, thereby avoiding the vortex caused by the suction force of the water outlet 12, and due to the blocking effect of the baffle, the water flow speed above the guide channel is much smaller than that at the water outlet 12, so that the probability of forming a vortex that sucks in air from the liquid level at the inlet of the guide channel 14 is greatly reduced. Therefore, the scheme provided by the present application solves the problem that the water pump easily sucks in air to form a vortex when pumping water from the water tank, thereby causing performance degradation and noise.

[0037] In some embodiments, the vortex preventing structure is an inner recess structure 13 formed on the wall of the water tank, and the bottom plate 131 of the inner recess structure 13 is a baffle located above the water outlet 12. The water tank provided by this embodiment can be formed by a blow molding process.

[0038] In some embodiments, the bottom plate of the inner recess structure 13 can be horizontally arranged, and the downward projection of the inner recess structure 13 can be square or other shapes, for example, when the inner recess structure 13 is arranged as a circular arc structure at the depth of the inner recess, the projection includes a circular arc at the depth of the inner recess of the inner recess structure 13.

[0039] In some embodiments, as shown in Figures 1-6 As shown, the water outlet 12 is arranged on the side of the water tank body 1, and the side of the water tank body 1 with the water outlet 12 is recessed to form an inner recess structure 13.

[0040] In the embodiment of Figures 1-6 In the embodiment of

[0041] When the distance between the lower surface of the bottom plate 131 of the concave structure 13 and the water outlet 12 is large, it can not be possible to effectively avoid the formation of a vortex above the water outlet 12, and therefore the distance between the lower surface of the bottom plate 131 of the concave structure 13 and the water outlet 12 is limited. It will be understood that, depending on the specific structure of the water tank body 1, the distance between the lower surface of the bottom plate 131 of the concave structure 13 and the water outlet 12 can be set to other values.

[0042] In Figures 1-6 some embodiments, the depth c of the concave structure 13 is not less than twice the inner diameter of the water outlet 12 to avoid the size of the baffle formed above the water outlet 12 being too small to block the formation of a vortex.

[0043] In some embodiments, as shown in Figures 7-8 , the water outlet 12 is arranged at the bottom of the water tank body 1 and close to one side of the water tank body 1, and the side of the water tank body 1 close to the water outlet 12 is concave to form the concave structure 13.

[0044] In Figures 7-8 some embodiments, the distance e between the lower surface of the bottom plate 131 of the concave structure 13 and the bottom of the water tank body 1 is greater than the inner diameter of the water outlet 12 and less than twice the inner diameter of the water outlet 12.

[0045] The distance e is set to be greater than the inner diameter of the water outlet 12 and less than twice the inner diameter of the water outlet 12, which can ensure that there is sufficient flow passage above the water outlet 12 to enable water to flow smoothly to the water outlet 12, and also enable the lower surface of the concave structure 13 to block the formation of a vortex.

[0046] In Figures 7-8 some embodiments, the depth d of the concave structure 13 from the edge of the water outlet 12 close to the outer side is set to be not less than twice the inner diameter of the water outlet 12.

[0047] In addition, the structure of the concave structure 13 can be in various forms:

[0048] As shown in the examples of Figures 1-2 and Figures 7-8 , in the width direction of the concave structure 13, the concave structure 13 extends through both ends of the water tank body 1.

[0049] As shown in the examples of Figures 3-4 , in the width direction of the concave structure 13, the concave structure 13 extends through one end of the water tank body 1.

[0050] As shown in the examples of Figures 5-6 , the concave structure 13 is a hole formed by concave recessing in the side of the water tank body 1. That is, neither end of the concave structure 13 in the width direction extends through the water tank body 1.

[0051] It should be noted that the width of the inner recess structure 13 in the direction of the end of the water tank body 1 is not limited, and the width of the inner recess structure 13 in the direction of the other end of the water tank body 1 needs to be greater than a certain value.

[0052] For example, in the example of Figures 3-4 , the inner recess structure 13 penetrates one end of the water tank body 1, and the width of the inner recess structure 13 from the center of the water outlet 12 to the direction of the penetrated end is not limited, and the width b of the inner recess structure 13 from the center of the water outlet 12 to the direction of the other end of the water tank body 1 is not less than 1.5 times the inner diameter of the water outlet 12. In the example of Figures 5-6 , the width b of the inner recess structure 13 on both sides of the center of the water outlet 12 is respectively set to be not less than 1.5 times the inner diameter of the water outlet 12. In the example of Figures 1-2 and Figures 7-8 , the width of the inner recess structure 13 on both sides of the center of the water outlet 12 is not limited.

[0053] The height h of the inner recess structure 13 is as small as possible under the requirement of the feasibility of the blow molding process, so as to avoid the influence of the inner recess structure 13 on the internal capacity of the water tank.

[0054] It can be understood that the inner recess structure 13 formed on the water tank body 1 is not limited to the above, and can also be other setting modes. For example, when the water outlet 12 is located at the bottom of the water tank and close to the middle position, the inner recess structure 13 can be formed by recessing from the top surface of the water tank body 1.

[0055] It can also be understood that the vortex preventing structure is not limited to the inner recess structure 13, and a baffle can also be arranged only in the internal space of the water tank. The baffle can be a horizontal baffle located above the water outlet 12, or a bent baffle body.

[0056] The embodiment of the present application also provides a toilet, which comprises a toilet body, a water pump and a water tank as described above; wherein the water inlet end of the water pump is connected with the water outlet 12 of the water tank, and the water outlet end is connected with the flushing water path, the rim washing water path and / or the human body washing water path of the toilet body.

[0057] When the toilet is flushed, the water pump draws water from the water tank and provides it to the flushing water path and / or the rim washing water path of the toilet body, so as to realize the flushing of the toilet. During the water pumping process of the water pump, due to the existence of the inner recess structure 13, the water flow velocity at the water outlet 12 in the water tank is stable, no vortex is generated, and the noise is small.
