Description

Technical Field

[0001] The present application relates to the field of water inlet structures in toilets, and in particular to a water inlet pipe, a water tank and a toilet. Background Art

[0002] The water inlet end of the water inlet pipe of the toilet tank is connected to the water inlet pipe (such as the tap water pipe), and the water outlet end is connected to the water inlet valve in the water tank. Due to the complexity of the internal structure of the water tank, especially the layout of key components such as the water inlet valve, after the water outlet end of the water inlet pipe is connected to the water inlet valve, the installation direction of the water inlet end of the water inlet pipe is significantly restricted.

[0003] In some scenarios, the water inlet end of the water inlet pipe can only be connected to the side of the toilet tank, and in some cases it can only be connected to the back of the toilet tank. This limitation requires the installer to perform precise measurements and planning before construction to ensure that the water inlet pipe can be connected to the tank at the best angle and direction to meet the installation requirements and facilitate future maintenance and repair. As a result, the water inlet pipe cannot meet the installation requirements in different scenarios, resulting in the problem of poor adaptability of the water inlet pipe.

[0004] Therefore, the present application studies a water inlet pipe with strong adaptability, so that the water inlet end of the water inlet pipe can be selectively connected to different positions of the water tank, thereby meeting the installation requirements in different scenarios.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The present application embodiment discloses a water inlet pipe. Figure 1 The water inlet pipe of this embodiment is applied to the water tank body, and the water inlet pipe includes a first hose 1, a second hose 2, a connector 3 and two connectors 4. The first hose 1 and the second hose 2 of this embodiment are both new braided hoses, which have the advantages of pressure resistance, corrosion resistance and wear resistance. The connector 3 can detachably connect the first hose 1 and the second hose 2, and the first hose 1 and the second hose 2 are rotatably connected, that is, when they need to be fixed, the first hose 1 and the second hose 2 are fixed by the connector 3. When the first hose 1 or the second hose 2 needs to be rotated, the connector 3 is disassembled to realize the rotation of the first hose 1 and the second hose 2.

[0034] When fixation is required, the first hose 1 and the second hose 2 are sealed and fixed by the connecting piece 3. When the second hose 2 is fixed, the first hose 1 can be rotated relative to the second hose 2 to change the angle direction; when the first hose 1 is rotated to the corresponding position, the first hose 1 and the second hose 2 are sealed and fixed by the connecting piece 3 to ensure smooth water inflow.

[0035] The connector 4 includes a first connector portion 41 and a second connector portion 42, and the first connector portion 41 and the second connector portion 42 are integrally formed, and the central axes of the first connector portion 41 and the second connector portion 42 are not on the same straight line. In some embodiments, the first connector portion 41 and the second connector portion 42 are vertically arranged, that is, the central axes of the two are perpendicular to each other. The first connector portions 41 of the two connectors 4 are respectively connected to the first hose 1 and the second hose 2. In this embodiment, the metal sleeve connected to the connector 4 is sleeved on the first hose 1 or the second hose 2, and then the connector 4 is fixed to the first hose 1 or the second hose 2 by riveting.

[0036] Reference Figure 2 In some embodiments, the connector 3 includes a mating portion 31, a plug-in portion 32 and a fixing portion 33. The mating portion 31 is connected to an end of the first hose 1 away from the first connecting portion 41. In this embodiment, the mating portion 31 is fixed to the first hose 1 by riveting; the plug-in portion 32 is connected to an end of the second hose 2 away from the first connecting portion 41. In this embodiment, the plug-in portion 32 is fixed to the second hose 2 by riveting.

[0037] The plug-in portion 32 is sealably plugged into the mating portion 31 and fixed by the fixing portion 33. In this embodiment, a sealing groove 5 is formed in the plug-in portion 32. A sealing ring (not shown in the figure) is sleeved on the sealing groove 5. The sealing ring is plugged into the mating portion 31 to achieve sealing. The sealing ring and the mating portion 31 have an interference fit. When the first hose 1 needs to be rotated, only a certain force is needed to overcome the friction between the sealing ring and the mating portion 31, so that the first hose 1 can be rotated to a corresponding angle or direction, so that it can be connected to the water tank body in different directions.

[0038] In some embodiments, the fixing portion 33 is a rotating ring, which is limited and rotated on the plug-in portion 32. In this embodiment, the plug-in portion 32 is integrally formed with a limiting ring 6, and the rotating ring is limited by the limiting ring 6. At the same time, the limiting ring 6 abuts against the end face of the matching portion 31 when the plug-in portion 32 is inserted into the matching portion 31, which can play a limiting role. The inner wall surface of the rotating ring is provided with an internal thread, and the outer wall surface of the matching portion 31 is provided with an external thread. During installation, the plug-in portion 32 is inserted into the matching portion 31, and the rotating ring is rotated so that the rotating ring and the matching portion 31 are screwed together through the internal thread and the external thread. When the first hose 1 needs to be rotated to change the direction or angle, it is only necessary to unscrew the rotating ring and rotate the first hose 1, so that the first hose 1 and the second hose 2 can be fixed conveniently, and the structure is simple, the manufacturing cost is low, and it is easy to operate.

[0039] In some embodiments, the mating portion 31 includes a limiting section 311 and a connecting section 312, the limiting section 311 and the connecting section 312 are integrally formed, the inner diameter of the connecting section 312 is larger than the outer diameter of the limiting section 311, the plug-in portion 32 is plugged into the connecting section 312 and abuts against the bottom wall of the connecting section 312, so that the insertion position of the plug-in portion 32 can be better limited.

[0040] In some embodiments, the water inlet pipe further includes a fixing ring 13, which is rotatably sleeved on the second connection portion 42. In this embodiment, a limiting ring 6 is also provided on the second connection portion 42, and the fixing ring 13 is also limitedly rotated on the second connection portion 42 by the limiting ring 6. At the same time, an internal thread is provided in the fixing ring 13, so that water can be conveniently inletted through the fixing ring 13 through threaded connection with other components.

[0041] The implementation principle of a water inlet pipe in an embodiment of the present application is: when the water inlet pipe is applied to a toilet water tank, the second hose 2 is connected to the water inlet valve in the water tank through the second connecting part 42. At this time, the first hose 1 can rotate relative to the second hose 2 to change the direction of the second connecting part 42 connected to the first hose 1, so that the second connecting part 42 can be arbitrarily connected to one of the three adjacent sides of the water tank (i.e., the side, the top, and the back), so as to enhance the adaptability of the water inlet pipe and better meet the installation requirements in different scenarios.

[0042] The present application also discloses a water tank. Figure 3 The water tank includes the above-mentioned water inlet pipe. In some embodiments, the water tank also includes a water tank body 7, a water inlet valve 8 and an angle valve 9. The water inlet valve 8 is installed in the water tank body 7. The second hose 2 is connected to the water inlet valve 8. In this embodiment, the second hose 2 is screwed and fixed to the water inlet valve 8 through the second connecting portion 42. The three adjacent surfaces of the water tank body 7 are all provided with installation openings 10, that is, the top, side and back of the water tank body 7 are all provided with installation openings 10. The installation openings 10 are all installed with angle valves 9. In this embodiment, the angle valve 9 is fixed to the installation opening 10 by screwing.

[0043] Reference Figure 4 and Figure 5 The angle valve 9 has a water inlet 11 and a connecting port 12. The central axes of the water inlet 11 and the connecting port 12 are perpendicular to each other. The water inlet 11 is connected to the installation port 10, that is, the water inlet 11 is used to connect to the tap water pipeline, etc. Figure 3 , the connecting port 12 is connected to the second connecting portion 42 of the first hose 1. In this embodiment, the first connecting portion 41 and the second connecting portion 42 are arranged vertically, and the second connecting portion 42 and the connecting port 12 are fixed by screwing. When the water inlet installation direction needs to be changed, it is only necessary to install the angle valve 9 on the corresponding water inlet 11, that is, the side, back or top of the water tank body 7, and then rotate the first hose 1 to the corresponding direction and screw it to the connecting port 12 of the angle valve 9, so that the water inlet pipe can be installed flexibly, so that the water tank can also be installed flexibly, and the water pipe layout before construction can also be more flexible and better adapted to more different scenarios.

[0044] In other embodiments, the installation positions of the first hose 1 and the second hose 2 may also be swapped, that is, the first hose 1 is connected to the water inlet valve 8, and the second hose 2 is connected to the angle valve 9 by changing the angle by rotating.

[0045] The implementation principle of a water tank in an embodiment of the present application is as follows: the water tank adopts a water inlet pipe, and since one of the three adjacent side surfaces can be selected, the water tank can be installed more flexibly.

[0046] The embodiment of the present application also discloses a toilet, which includes the water tank mentioned above.

[0047] The implementation principle of a toilet in an embodiment of the present application is that the water tank of the toilet can be installed flexibly so as to meet the installation requirements in different scenarios.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
