[0032] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0033] refer to Figure 1 , Figure 2 and Figure 4 The present embodiment provides an overflow structure, which is installed on a liquid storage bottle 400 of a toilet. The overflow structure includes a connecting component 100 and a nozzle component 200. An overflow channel 120 is provided in the connecting component 100, and a liquid outlet channel 210 is provided in the nozzle component 200. The liquid storage bottle 400 and the liquid outlet channel 210 are both connected to the overflow channel 120, so as to ensure that the liquid will not flow to the floor when adding liquid.

[0034] The connection assembly 100 is connected to the spray head assembly 200, and the spray head assembly 200 is arranged below the connection assembly 100. The connection assembly 100 is provided with an overflow channel 120, and the spray head assembly 200 is provided with a liquid outlet channel 210. The two ends of the overflow channel 120 are respectively connected to the liquid storage bottle 400 and the liquid outlet channel 210, and the other end of the liquid outlet channel 210 is provided with a liquid outlet 211 connected to the toilet bowl 510. During the liquid storage bottle 400 filling process, the excess liquid after filling can flow through the overflow channel 120 and the liquid outlet channel 210 in sequence, and flow out from the liquid outlet 211 into the toilet bowl 510 of the toilet.

[0035] In this embodiment, an overflow channel 120 is provided which is connected to the liquid storage bottle 400, and the overflow channel 120 is connected to the liquid outlet channel 210. When too much liquid is added, the excess liquid from the liquid storage bottle 400 can flow through the overflow channel 120 and the liquid outlet channel 210 in sequence, and finally flow out from the liquid outlet 211 into the toilet bowl 510. This ensures that the liquid will not flow onto the floor when adding liquid, and also allows the determination of whether the liquid storage bottle 400 is full by observing whether there is liquid flowing out of the liquid outlet 211, thereby avoiding the waste of a large amount of liquid consumables. Such an overflow structure is simple and reliable in function.

[0036] refer to Figure 2 and Figure 4The axis of the overflow channel 120 (not shown) is perpendicular to the axis of the liquid outlet channel 210 (not shown), wherein the axis of the overflow channel 120 can be in the vertical direction, and the axis of the liquid outlet channel 210 can be in the horizontal direction. In this way, the liquid from the exhaust channel 110 can be guided from a high place to a low place under the action of gravity by utilizing the height difference of the terrain, so that the liquid can flow naturally and flow more smoothly through the overflow channel 120 to the liquid outlet channel 210.

[0037] refer to Figure 2 In addition to the overflow channel 120, the connecting component 100 also includes an exhaust channel 110, which is connected to the overflow channel 120. An exhaust hole 111 is opened at the output end of the exhaust channel 110, and the exhaust hole 111 is connected to the overflow channel 120, and the diameter of the exhaust hole 111 is smaller than the diameter of the input end of the overflow channel 120.

[0038] One end of the exhaust channel 110 and one end of the liquid outlet channel 210 are respectively connected to the overflow channel 120, and the other end of the exhaust channel 110 is connected to the liquid storage bottle 400. The other end of the liquid outlet channel 210 is provided with a liquid outlet 211 connected to the toilet bowl 510. During the process of adding liquid to the liquid storage bottle 400, the excess liquid after filling can flow through the exhaust channel 110, the overflow channel 120 and the liquid outlet channel 210 in sequence, and flow out from the liquid outlet 211 into the toilet bowl 510 of the toilet.

[0039] Among them, the exhaust channel 110 and the overflow channel 120 can be connected to the intake channel 130 respectively. The liquid sprayed from the exhaust hole 111 can flow downward to the overflow channel 120 under the action of gravity, and the diameter of the exhaust hole 111 is smaller than the diameter of the input end of the overflow channel 120, so that the liquid flowing out of the exhaust hole 111 can pass through the overflow channel 120 more easily.

[0040] Although in this embodiment, the exhaust channel 110 and the overflow channel 120 are indirectly connected through the air intake channel 130, the present disclosure is not limited thereto. For example, the exhaust hole 111 may also be directly connected to the overflow channel 120 without passing through the air intake channel 130, so that the liquid overflowing from the exhaust channel 110 can flow through the overflow channel 120 through the exhaust hole 111.

[0041] refer to Figures 2 to 4 In addition to the overflow channel 120 and the exhaust channel 110, the connecting component 100 can also be provided with an intake channel 130 connected to the outside atmosphere, a liquid inlet channel 140, an injection hole 141 and an intake cavity 150, and the intake channel 130 is respectively connected to the overflow channel 120 and the exhaust channel 110.

[0042] Among them, the liquid inlet channel 140 is used to flow in the mixed foaming agent and water, the injection hole 141 connects the liquid inlet channel 140 and the air suction chamber 150, the axis of the liquid inlet channel 140 (not shown) is not parallel to the axis of the injection hole 141 (not shown), one end of the air suction channel 130 and one end of the liquid outlet channel 210 are respectively connected to the air suction chamber 150, and the other end of the air suction channel 130 can be connected to the outside air, and the other end of the liquid outlet channel 210 is provided with a liquid outlet 211 connected to the toilet bowl 510.

[0043] Since the axis of the liquid inlet channel 140 (not shown) is not parallel to the axis of the injection hole 141 (not shown), the fluid flowing from the liquid inlet channel 140 into the injection hole 141 will impact the corresponding hole wall, making the fluid in an agitated state, so that the fluid flowing into the injection hole 141 has a tendency to move in a circumferential direction, which helps the process of the fluid being injected from the injection hole 141 into the suction chamber 150 to generate a scattered liquid beam and produce a Venturi effect, which facilitates better air suction from the suction channel 130 and mixes the foaming agent, water and air in the suction chamber 150. It should be noted that the Venturi effect belongs to the prior art and will not be described in detail here.

[0044] In addition, the air suction chamber 150 of the connecting component 100 is also provided with a foaming member, wherein the foaming member can be a foaming net 151. For example, the air suction chamber 150 also includes two foaming nets 151, and the two foaming nets 151 are arranged at the bottom of the air suction chamber 150 and aligned with the position of the injection hole 141, so that the water flow ejected from the injection hole 141 is directly sprayed onto the foaming net, which can quickly and massively foam, and a spacer ring 152 is also provided between the two foaming nets 151 for interruption, and the spacer ring 152 is a ring-shaped member that allows liquid and air to pass through. The mixed foaming agent, water and air can generate a large amount of foam after passing through the two foaming nets 151. The foaming net 151 and the spacer ring 152 belong to the prior art and will not be described in detail here. It should be noted that in other embodiments, other numbers of foaming nets 151 and corresponding spacer rings 152 may also be provided, which will not be described in detail here.

[0045] refer to Figure 2 and Figure 3 The air intake channel 130 is connected to the liquid outlet channel 210, and the air exhaust channel 110 and the overflow channel 120 are respectively connected to the air intake channel 130. The connecting area between the air exhaust channel 110 and the air intake channel 130 is arranged above the connecting area between the overflow channel 120 and the air intake channel 130, so that the liquid flowing out of the air exhaust hole 111 can automatically flow to the overflow channel 120 under the action of gravity.

[0046] A guide surface 131 is provided on the air intake channel 130, and the guide surface 131 is provided between the output end of the exhaust channel 110 and the input end of the overflow channel 120. The guide surface 131 can play a guiding role to guide the liquid from the exhaust channel 110 to flow into the overflow channel 120. Of course, the guide surface 131 can be a plane or other transitional curved surface.

[0047] The output end of the air suction channel 130 is communicated with the input end of the air suction chamber 150, and the output end of the air suction chamber 150 is communicated with the liquid outlet channel 210. The input end of the overflow channel 120 is communicated with the air suction channel 130, and the output end of the overflow channel 120 is communicated with the liquid outlet channel 210, and the input end of the overflow channel 120 can be located above the input end of the air suction chamber 150.

[0048] When the foam shield is working, the mixture of the foaming agent and water passes through the liquid inlet channel 140, and then sprays out high-speed water flow through the spray hole 141, generating a Venturi effect in the air suction chamber 150, forming a negative pressure to suck air from the air suction channel 130, and the high-speed water flow mixes with the sucked air when passing through the foaming net 151 to generate a large amount of foam, and the foam is discharged from the liquid outlet channel 210 to the water seal of the toilet bowl 510 to form a foam shield. It should be noted that the foam shield belongs to the prior art and will not be described in detail here.

[0049] During the foaming process, a small amount of foam in the liquid outlet channel 210 will return to the air intake channel 130 through the overflow channel 120. However, under the action of the airflow in the air intake channel 130, the small amount of foam can be sucked back into the air intake cavity 150, thereby ensuring that the foam does not flow out of the air intake channel 130 and keeping the air intake channel 130 unobstructed.

[0050] refer to Figures 1 to 4 The connecting component 100 is a four-way tubular structure. The exhaust channel 110, the liquid inlet channel 140 and the air suction channel 130 are respectively formed in the three interfaces of the connecting component 100. The overflow channel 120 and the air suction chamber 150 are formed in the fourth interface of the connecting component 100. The fourth interface is radially inserted into the nozzle assembly 200. The overflow channel 120 and the air suction chamber 150 can be interconnected or independently arranged.

[0051] In addition, the connection assembly 100 and the nozzle assembly 200 can be manufactured by an integral molding process or a separate molding process. It should be noted that the integral molding process and the separate molding process belong to the prior art and will not be described in detail here.

[0052] refer to Figure 4 The nozzle assembly 200 is further provided with a water outlet 221 and a water outlet channel 220 connected with the water outlet 221. The water outlet channel 220 and the liquid outlet channel 210 may be connected with each other or may be independently provided with each other.

[0053] For example, a water outlet 221 is provided at the end of the water outlet channel 220, and the water outlet channel 220 and the liquid outlet channel 210 are independently isolated and arranged, and the water outlet 221 is located below the liquid outlet 211. The water from the water outlet channel 220 can be supplied to the toilet to flush the toilet bowl 510. This structure can combine the liquid outlet channel 210 for foam and the water outlet channel 220 for brush ring water, so that the toilet has a simpler pipeline setting.

[0054] This overflow structure is not only provided with an exhaust channel 110, an overflow channel 120, a liquid outlet channel 210, an air suction channel 130, a liquid inlet channel 140, an injection hole 141, an air suction cavity 150 and a water outlet channel 220, but also has a liquid outlet 211 and a water outlet 221 at the ends of the liquid outlet channel 210 and the water outlet channel 220. In addition, the overflow structure is also provided with a valve assembly 300, which can switch and control the water supply of the water outlet channel 220. The valve assembly 300 belongs to the prior art in this field and will not be described in detail here.

[0055] refer to Figures 1 to 5 The present embodiment provides a toilet, which includes a toilet seat 500, a liquid storage bottle 400 and an overflow structure. A toilet bowl 510 is arranged on the toilet seat 500, and the liquid storage bottle 400 is arranged in the toilet seat 500. Please refer to the above detailed description for the overflow structure, which will not be repeated here.

[0056] A liquid adding assembly 420 is disposed on the top of the toilet seat 500 , an output end of the liquid adding assembly 420 is communicated with a liquid adding channel 410 , and an output end of the liquid adding channel 410 is communicated with the liquid storage bottle 400 .

[0057] The liquid storage bottle 400 is provided with a mixed liquid outlet (not shown). When the foam shield is working, the water and the foaming agent in the foam shield mixing chamber (not shown) in the liquid storage bottle 400 are fully mixed and then discharged from the mixed liquid outlet, and pass through the liquid inlet channel 140, the injection hole 141, the air suction chamber 150, the foaming net 151 and the liquid outlet channel 210 in sequence, and flow from the liquid outlet 211 into the toilet bowl 510.

[0058] The liquid storage bottle 400 is provided with an exhaust port (not shown in the figure). The liquid storage bottle 400 is filled with liquid from the liquid adding assembly 420. The liquid flows into the liquid storage bottle 400 through the liquid adding channel 410. When the liquid storage bottle 400 is full of liquid, the liquid is discharged from the exhaust port, and can pass through the exhaust channel 110, the exhaust hole 111, the overflow channel 120 and the liquid outlet channel 210 in sequence, and flow into the toilet bowl 510 from the liquid outlet 211. It should be noted that when the liquid storage bottle 400 is filled with liquid, when the liquid is observed to flow out from the liquid outlet 211, it can be said that the liquid storage bottle 400 is filled with liquid. In this way, it can be ensured that the liquid will not flow to the floor when adding liquid. At the same time, it can also be judged whether the liquid storage bottle 400 is full by observing whether there is liquid flowing out of the liquid outlet 211, thereby avoiding the waste of a large amount of liquid consumables. Such an overflow structure is simple and reliable in function.

[0059] In other embodiments, the overflow channel 120 and the exhaust channel 110 may also be provided independently of each other (not shown), and the height of the highest point of the exhaust channel 110 is higher than that of the overflow channel 120 .
