Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a water outlet device and a toilet. Background Technology

[0002] There are two types of toilets: those with a water tank and those without. In toilets with a water tank, the water pump in the tank pumps water to the flush pipe when flushing is needed. However, because there is air in the flush pipe, bubbles appear inside the ceramic body of the toilet during flushing, which seriously affects the flushing effect.

[0003] Therefore, in related technologies, a toilet power flushing device is proposed. A vacuum breaker is connected to the water pump outlet via a first water pipe. The vacuum breaker includes a main body and an air outlet pipe, which communicates with the inner cavity of the main body. A movable component is provided within the inner cavity of the main body to separate the inner cavity from the air outlet pipe. When flushing is required, the water pump starts, and water from the tank enters the vacuum breaker through the first water pipe. The movable component moves upward, expelling air from the air outlet pipe. This effectively prevents air from entering the toilet ceramic body with the water flow, reducing the occurrence of bubbling within the toilet ceramic body.

[0004] In the aforementioned toilet power flushing device, the inclusion of a vacuum breaker not only increases the difficulty of assembling the toilet but also increases its manufacturing cost. Utility Model Content

[0005] The purpose of this utility model is to provide a water outlet device and a toilet, which can effectively solve the problem of bubbling in the ceramic body of the toilet, while reducing the assembly difficulty and manufacturing cost of the toilet.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a water outlet device, including a water tank, a water pump, and a connecting pipe integrally formed in the water tank. The water pump is disposed in the water tank and is capable of drawing water from the water tank. The connecting pipe is at least partially located in the water tank and connected to the water outlet end of the water pump. The portion of the connecting pipe located in the water tank has a pressure relief recess that communicates with the outside. The pressure relief recess is capable of venting gas from the water pump and the connecting pipe.

[0008] In one embodiment, the pressure relief recess is a pressure relief groove, and the depth of the pressure relief groove gradually decreases from bottom to top.

[0009] In one embodiment, the water pump is connected to the connecting pipe via a water pump outlet pipe, the water pump outlet pipe is sleeved on the connecting pipe, and the lower end of the pressure relief groove is exposed outside the water pump outlet pipe.

[0010] In one embodiment, the water pump outlet pipe is a flexible pipe, and multiple support ribs are provided at intervals along the circumference of the connecting pipe in the pressure relief groove, with the support ribs protruding from the outer wall surface of the connecting pipe.

[0011] In one embodiment, a reinforcing rib is provided on the outer wall of the connecting pipe, and the lower end face of the water pump outlet pipe abuts against the reinforcing rib.

[0012] In one embodiment, the sidewall of the connecting pipe is provided with guide elements at intervals along the circumference, the guide elements extend in the vertical direction, and a guide channel connecting the pressure relief groove is formed between adjacent guide elements.

[0013] In one embodiment, the outer side wall of the water tank is recessed to form a relief groove, the connecting pipe is inserted into the relief groove, and the inner side wall of the water tank has a protrusion corresponding to the position of the relief groove, the connecting pipe passing through the protrusion.

[0014] In one embodiment, the water outlet device further includes a rectifier, which is disposed inside the water tank and forms a buffer groove with the inner side wall of the water tank, the top surface of the protrusion, and one side wall of the pressure relief recess of the connecting pipe.

[0015] In one embodiment, the outlet of the connecting pipe includes a first outlet and a second outlet.

[0016] Secondly, a toilet, characterized in that it includes a ceramic body, a water-using component, and a water outlet device as described above, wherein the water-using component is disposed on the ceramic body, and the connecting pipe is connected to the water-using component.

[0017] The beneficial effects of this utility model are as follows: By setting a pressure relief recess on the connecting pipe, the gas in the water pump and connecting pipe can be discharged from the pressure relief recess when water is supplied through the water tank. This effectively prevents air from entering the water-using equipment with the water flow, reducing the occurrence of bubbling in water-using equipment, not limited to toilets. Moreover, the connecting pipe and the water tank are integrally formed, eliminating the need for subsequent assembly and reducing the manufacturing process and processing costs of the water outlet device. It is worth emphasizing that, compared to a vacuum breaker, since the connecting pipe is located inside the water tank, even if water flows out from the pressure relief recess, it will flow back into the water tank and will not flow out of the water outlet device, causing leakage. Therefore, there is no need to set moving parts, further reducing the manufacturing cost and subsequent maintenance cost of the water outlet device, thereby reducing the manufacturing cost of toilets using this water outlet device.

[0028] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 8 As shown, an embodiment of this utility model provides a water outlet device, which can be used in toilets or other water-using equipment with water demand. The water outlet device includes a water tank 1, a water pump, and a connecting pipe 2 integrally formed in the water tank 1. The water pump is located inside the water tank 1 and can draw water from the water tank 1. The connecting pipe 2 has a water inlet 23 located inside the water tank 1, which is connected to the water outlet of the water pump. The portion of the connecting pipe 2 located inside the water tank 1 has a pressure relief recess 24 that communicates with the outside, allowing gas from the water pump and the connecting pipe 2 to be discharged from the pressure relief recess 24.

[0033] The aforementioned water outlet device, by providing a pressure relief recess 24 on the connecting pipe 2, allows air from the water pump and connecting pipe 2 to be discharged through the pressure relief recess 24 when water is supplied through the water tank 1. This effectively prevents air from entering the water-using equipment with the water flow, reducing bubbling phenomena in water-using equipment, not limited to toilets. Furthermore, the connecting pipe 2 is integrally formed with the water tank 1, eliminating the need for subsequent assembly and reducing the manufacturing process and processing costs of the water outlet device and the water-using equipment using it. It is worth emphasizing that, compared to a vacuum breaker, since the pressure relief recess 24 is located inside the water tank 1, even if water flows out of the pressure relief recess 24, it will flow back into the water tank 1 without leaking out of the water outlet device, thus eliminating the need for moving parts. This further reduces the manufacturing and maintenance costs of the water outlet device, thereby lowering the manufacturing cost of the water-using equipment using it.

[0034] Furthermore, since the height of the pressure relief recess 24 is higher than the maximum water level allowed by the water tank 1, air will enter the connecting pipe 2 from the pressure relief recess 24 after the water is discharged, thus breaking the vacuum state in the connecting pipe 2 and preventing water in the water tank 1 from being siphoned into the water-using device.

[0035] In some embodiments, the axis of the inlet 23 extends vertically, and the connecting pipe 2 also includes an outlet located outside the water tank 1 to facilitate connection with the water-using components in the water-using equipment. To provide clearance space for the water-using components, a clearance groove is formed in the outer wall of the water tank 1, and part of the connecting pipe 2 is inserted into the clearance groove so that the outlet is located within the clearance groove. It is understood that the clearance groove is simultaneously formed within the water tank 1 to create a protrusion 11, through which the connecting pipe 2 passes. Specifically, to improve the structural strength of the connecting pipe 2, a reinforcing rib 6 is also provided on the side wall of the connecting pipe 2, extending vertically and connecting to the top surface of the protrusion 11.

[0036] refer to Figures 4-7 As shown, the pressure relief recess 24 adopts a pressure relief groove, and the depth of the pressure relief groove gradually decreases from top to bottom, so that the water flows out laterally, which reduces the possibility of splashing compared to the radial flow along the inlet 23.

[0037] Specifically, in order to reduce the complexity of the molds used to manufacture the water tank 1 and the connecting pipe 2, the upper end of the pressure relief groove extends to the upper end face of the connecting pipe 2.

[0038] In some embodiments, to reduce the difficulty of connecting the connecting pipe 2 and the water pump, the water pump is connected to the inlet 23 of the connecting pipe 2 through the water pump outlet pipe 8. The water pump outlet pipe 8 is a flexible pipe, specifically a rubber pipe or a plastic pipe. The water pump outlet pipe 8 is sleeved on the connecting pipe 2 and forms a pressure relief gap with the connecting pipe 2 at the position of the pressure relief groove. The lower end of the pressure relief groove is exposed outside the water pump outlet pipe 8. In order to limit the position of the water pump outlet pipe 8 on the connecting pipe 2, there is a gap between the upper end face of the reinforcing rib 6 and the upper end face of the connecting pipe 2. When the water pump outlet pipe 8 is sleeved on the connecting pipe 2, its lower end face abuts against the upper end face of the reinforcing rib 6.

[0039] In the current embodiment, the water pump outlet pipe 8 is clamped to the connecting pipe 2 to achieve a tight connection between the water pump outlet pipe 8 and the connecting pipe 2. To prevent the water pump outlet pipe 8 from deforming due to the clamp and encroaching on the space of the pressure relief groove, multiple support ribs 7 are spaced apart circumferentially along the connecting pipe 2 within the pressure relief groove. The height of the support ribs 7 (defined as the radial extension dimension of the support rib 7 along the inlet 23) is greater than the wall thickness of the connecting pipe 2, so that the support ribs 7 protrude from the outer wall surface of the connecting pipe 2, thereby supporting the water pump outlet pipe 8. More specifically, the vertical height of the pressure relief groove is greater than 1 mm, the distance between adjacent support ribs 7 is greater than 2 mm, and the effective flow area of ​​the pressure relief groove is greater than 3% of the effective flow area of ​​the inlet 23.

[0040] refer to Figure 5 and Figure 7As shown, a guide 4 extending along the axial direction of the inlet 23 is also provided on the side wall of the connecting pipe 2. The guide 4 is also located in the water tank 1. A guide channel connecting the pressure relief recess 24 is formed between adjacent guides 4. The water flowing out of the connecting pipe 2 through the pressure relief groove is guided by the guide 4 and enters the water tank 1 through the guide channel along the pipe wall of the connecting pipe 2, further reducing the possibility of water flowing out of the pressure relief groove splashing everywhere.

[0041] Specifically, the flow guide 4 includes a first flow guide and a second flow guide. The first flow guide is connected to the supporting rib 7 in a one-to-one correspondence. More specifically, the first flow guide and the supporting rib 7 are integrally formed. There are two second flow guides, located on both sides of the pressure relief groove. It is worth noting that a limiting step is formed on the flow guide 4, which can also restrict the position of the water pump outlet pipe 8 on the connecting pipe 2.

[0042] In other embodiments, the pressure relief recess 24 may also be a pressure relief hole provided through the side wall of the connecting pipe 2, which will not be described in detail here.

[0043] Existing toilet flushing functions include a main flush and a brush seat flush; therefore, the water-using components of a toilet include a main flush component and a brush seat flush component. Based on this, refer to... Figure 3 As shown, when the aforementioned water outlet device is applied to a toilet, the outlet of the connecting pipe 2 includes a first outlet 21 and a second outlet 22. The first outlet 21 is used to connect to the main flushing assembly of the toilet, and the second outlet 22 is used to connect to the brush ring flushing assembly of the toilet. That is, the connecting pipe 2 adopts a T-junction structure, and both the first outlet 21 and the second outlet 22 extend out of the water tank 1 and are located in the clearance groove. It can be understood that the clearance groove can also avoid the ribs installed on the toilet.

[0044] In some embodiments, the water outlet device further includes a rectifier 5, which is connected to the connecting pipe 2, the inner wall of the water tank 1, and the top surface of the protrusion 11. This rectifier 5 works in conjunction with the connecting pipe 2 to form a buffer groove, where one side wall of the pressure relief recess 24, the side wall of the water tank 1, and the top surface of the protrusion 11 are pre-stored. The buffer groove contains a certain amount of water. It is understood that due to the protrusion 11, the water flowing out of the pressure relief recess 24 will impact the top surface of the protrusion 11, causing splashing. The rectifier 5 allows the water flowing out of the pressure relief recess 24 to flow into the buffer groove and be buffered by the pre-stored water, reducing the probability of splashing.

[0045] Specifically, the end of the guide member 4 away from the pressure relief recess 24 extends to the top surface of the protrusion 11, and the height of the rectifier 5 is greater than 40mm.

[0046] refer to Figure 1As shown, the water outlet device also includes an inlet valve 3, which is connected to the water tank 1 and is used to control the connection and disconnection between the water tank 1 and an external water source, such as a domestic water pipe, so as to replenish water into the water tank 1 when the water level in the water tank 1 drops significantly.

[0047] An embodiment of this utility model also proposes a toilet, including a ceramic body, the aforementioned water outlet device, and a water-using component. The flushing component is disposed on the ceramic body, and the connecting pipe 2 of the water outlet device is connected to the water-using component.

[0048] The water outlet device of the toilet described above has a simple structure, is easy to assemble, and has low manufacturing cost. Therefore, the manufacturing cost of a toilet including this water outlet device is low.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
