Description

Technical Field

[0001] The invention belongs to the technical field of intelligent toilets and relates to a down-flushing structure of an intelligent toilet. Background Art

[0002] There are two types of existing smart toilets. One is equipped with a water tank, and tap water enters through the water inlet valve and then flows from the water tank to the ceramic inside the toilet body for flushing. The other is directly connected to the external water pipe through a control valve, and the tap water inside the toilet body is directly connected to the external water pipe for flushing the ceramic inside the toilet body.

[0003] For example, Chinese patent application [Authorization Announcement No.: CN211621837U] discloses a pressurized flushing toilet with a water tank, which is characterized in that it includes a toilet body and a pressurized flushing component, and the pressurized flushing component includes a water tank, a water tank inlet pipe, a water tank outlet pipe, a booster pump and a flushing water pipe; one end of the water tank inlet pipe is connected to the tap water pipe through a constant flow and constant pressure valve, and the other end of the water tank inlet pipe is connected to the water tank; one end of the water tank outlet pipe is connected to the water tank, and the other end is connected to the booster pump; one end of the flushing water pipe is connected to the booster pump, and the other end is connected to the toilet bowl of the toilet body; a water inlet switch is provided on the flushing water pipe, and the booster pump is electrically connected to the water inlet switch.

[0004] In order to maintain a constant water pressure in the water inlet pipe entering the water tank, the above-mentioned structure is achieved by providing a constant flow and constant pressure valve at the water inlet pipe of the water tank to avoid excessive water pressure fluctuations. In order to improve the flushing effect of the water tank, a booster pump is provided between the water outlet pipe of the water tank and the flushing water pipe to increase the water pressure of the flushing water, thereby improving the flushing effect. In order to ensure that the toilet is flushed cleanly when flushing, the existing lower flushing port is used to improve the flushing effect and ensure that the sewage can be completely flushed out through the sewer pipe. The flushing head of the flushing water pipe is set opposite the sewer pipe. For the purpose of energy saving, the amount of flushing water is small, the water outlet end of the flushing water pipe is set horizontally, and the water inlet of the sewer pipe is low, resulting in the water outlet end of the flushing water pipe being unable to be set opposite the water inlet of the sewer pipe, which will result in poor flushing effect. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a down-flush structure for an intelligent toilet. The technical problem to be solved by the present invention is: how to solve the problem that the existing down-flush structure has poor flushing effect while saving energy.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A down-flush structure for an intelligent toilet, the intelligent toilet comprising a barrel body and a control chamber arranged on the barrel body, a control valve being arranged in the control chamber, the outlet end of the control valve being connected to a sewer pipe, and the control valve controlling the on-and-off of an external water pipe and the sewer pipe, characterized in that the down-flush structure comprises a constant pressure valve arranged in the barrel body, the water inlet end of the constant pressure valve being connected to the above-mentioned sewer pipe, and the water outlet end being connected to a flush pipe, the lower end of the barrel body having a water outlet chamber, the water outlet chamber being provided with a water outlet, the water outlet chamber having a mounting wall arranged opposite to the water outlet, the flush pipe having a water outlet portion mounted in the middle of the mounting wall, the mounting wall being inclined from bottom to top toward the direction of the water outlet, the water outlet portion being located in the barrel body and the upper top wall being inclined downward in the direction toward the water outlet chamber, and the outlet of the water outlet portion being arranged opposite to the water outlet.

[0008] The external water inlet pipe is connected to the control valve, and the outlet end of the control valve is connected to the sewer pipe. When the smart toilet is flushed, the control valve is opened so that the tap water from the external water inlet pipe can enter the sewer pipe and pass through the constant pressure valve. The constant pressure valve can increase the pressure when the water pressure is too low, and reduce the pressure when the water pressure is high, so as to keep the water pressure in the sewer pipe constant, and then flush it out from the flush pipe through the outlet end of the constant pressure valve, thereby achieving the purpose of water saving. Then the water flow speed flushed out of the flush pipe will also be constant and the water pressure will be low. Therefore, the water flow direction of the flush pipe needs to be set directly opposite the water outlet of the water outlet chamber to ensure better flushing. In order to improve the washing effect, a mounting wall is provided on the water outlet cavity at the lower end of the barrel body, the mounting wall is arranged opposite to the water outlet, and the mounting wall is arranged inclined inwardly from bottom to top, and then the water outlet of the flushing pipe is installed in the middle of the mounting wall. The inclination of the mounting wall is coordinated with the inclination of the top wall of the water outlet wall to increase the downward flushing angle of the tap water flushed out of the water outlet, so that the water flowing out from the outlet of the water outlet can better be arranged opposite to the water outlet, thereby improving the flushing effect. In addition, the arrangement of the mounting wall makes it necessary for the water outlet to be installed without being close to the bottom of the barrel body, which can facilitate installation and save energy while also ensuring the flushing effect.

[0009] In the above-mentioned down-flush structure of the smart toilet, the outlet of the water outlet is circular, and the inner diameter of the water outlet gradually decreases near the outlet.

[0010] The shape of the outlet is set so that the water introduced into the water outlet cavity will not splash everywhere, and the diameter setting allows the water outlet part to further enhance the water pressure after the diameter at the outlet is reduced, so that the water pressure rushing into the water outlet cavity is increased, thereby improving the flushing effect.

[0011] In the above-mentioned down-flush structure of the smart toilet, the upper top wall of the water outlet is arc-shaped, and the upper top wall is bent downward along its width direction.

[0012] The design of the upper top wall allows the tap water entering the water outlet from the flush pipe to flow smoothly along the upper top wall without generating a large impact force that affects the flushing of the toilet, thereby improving the stability of the lower flushing structure.

[0013] In the above-mentioned down-flush structure of the smart toilet, the flush pipe includes a tube body and the above-mentioned water outlet part, the water outlet part is tubular and is threadedly connected to the tube body, one end of the water outlet part protrudes radially to form a limit stop edge set in the water outlet cavity, and the water outlet part is provided with at least two sealing gaskets and a locking nut, one of the sealing gaskets is located between the limit stop edge and the mounting wall, and the other sealing gasket is located between the locking nut and the outer wall of the barrel body, and the locking nut and the limit stop edge cooperate to tighten the multiple sealing gaskets.

[0014] During installation, first put one of the sealing gaskets on the water outlet part, and then embed the water outlet part into the barrel body. At this time, the other end of the water outlet part passes through the water outlet cavity, and the other sealing gasket can be put on the water outlet part and located outside the water outlet cavity. Then, through the cooperation of the locking nut and the limit stop edge, the two sealing gaskets are squeezed against each other so that the water outlet part can be quickly installed on the barrel body, and then the water outlet part and the pipe body are threadedly connected, which realizes the rapid installation of the flush pipe and the barrel body and improves the convenience of installation.

[0015] In the above-mentioned down-flush structure of the smart toilet, a deformation-dispensing groove is provided on the outer wall of the water outlet portion along the length direction, and the deformation-dispensing groove is arranged close to the upper top wall.

[0016] Since there will be water flow inside the water outlet cavity when flushing, the sealing gasket needs to be pressed against the installation wall through the limit stop during installation. The sealing gasket is a flexible structure, so it needs a certain deformation space during extrusion, and the installation wall is inclined inward from bottom to top, so the deformation of the sealing gasket near the upper top wall will be larger during extrusion. Therefore, a deformation clearance groove is opened on the outer side wall of the water outlet to facilitate the deformation of the sealing gasket and avoid circumferential rotation of the deformed sealing gasket, thereby improving the convenience of sealing gasket installation and stability during use.

[0017] In the above-mentioned down-flush structure of the smart toilet, there are two sealing gaskets, and the side walls of the two sealing gaskets are opposite to each other and have deformable walls inclined from the inside to the outside in a direction away from each other, and the deformable walls respectively abut against the inner and outer side walls of the barrel body.

[0018] In order to facilitate the installation of the water outlet part, the installation wall in the water outlet cavity is tilted. The tilted setting will cause the ordinary flat sealing gasket to easily have an installation gap. Therefore, the present application uses deformable walls on the opposite side walls of the two sealing gaskets, and the deformable walls are tilted to facilitate deformation and positioning. They can also be partially embedded in the barrel body during installation to further improve the installation stability.

[0019] In the above-mentioned down-flush structure of the smart toilet, the inclination angle of the deformable wall of the sealing gasket located inside the barrel body is smaller than the inclination angle of the deformable wall of the sealing gasket located outside the barrel body.

[0020] Since the barrel body will be subjected to multiple water impacts during long-term use, the contact area between the gasket and the installation wall needs to be increased to ensure the stability of the gasket seal. Therefore, in order to facilitate installation while improving the stability of the gasket setting, the inclination angle of the gasket inside the barrel body is set to be smaller, while the inclination angle of the gasket outside the barrel body is larger, which is convenient for the extrusion deformation of the locking nut and easy installation.

[0021] In the above-mentioned down-flush structure of the smart toilet, the limit stop edge and the sealing gasket are both annular, and the outer diameter of the limit stop edge is larger than the outer diameter of the sealing gasket located in the barrel body.

[0022] The setting of the outer diameter of the limit stop edge and the sealing gasket enables the limit stop edge to stably press the sealing gasket in the barrel body against the installation wall, thereby improving the sealing effect.

[0023] In the above-mentioned down-flush structure of the smart toilet, the outlet of the constant pressure valve is set upward, and the barrel body is provided with a limiting hole outside the water outlet cavity for the flushing pipe to pass through. The flushing pipe is connected to the water outlet of the constant pressure valve and bends downward to pass through the limiting hole.

[0024] By connecting the flush pipe with the water outlet end of the constant pressure valve and bending it downward to pass through the limit hole, the flush pipe here enters the flush pipe from the upper end of the constant pressure valve. The downward bending accelerates the flow rate of tap water and increases the flushing effect of the flush pipe.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. By inclining the installation wall in conjunction with the incline of the top wall of the water outlet wall, the downward flushing angle of the tap water flushed out of the water outlet is increased, so that the water flowing out of the water outlet can be better aligned with the water outlet, thereby improving the flushing effect. In addition, the installation wall does not require the water outlet to be installed close to the bottom of the barrel, which can facilitate installation and save energy while also ensuring the flushing effect.

[0027] 2. During installation, first put one of the sealing gaskets on the water outlet part, and then embed the water outlet part into the barrel body. At this time, the other end of the water outlet part passes through the water outlet cavity, and the other sealing gasket can be put on the water outlet part and located outside the water outlet cavity. Then, through the cooperation of the locking nut and the limit stop edge, the two sealing gaskets are squeezed against each other so that the water outlet part can be quickly installed on the barrel body. Then, the water outlet part and the pipe body are threaded together, which realizes the rapid installation of the flush pipe and the barrel body and improves the convenience of installation.

DETAILED DESCRIPTION

[0036] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0037] like Figure 1 As shown, the down-flush structure of the smart toilet includes a barrel body 1 and a control chamber 11 arranged on the barrel body 1, a control valve 2 is arranged in the control chamber 11, and the outlet end of the control valve 2 is connected to the sewer pipe 3. The control valve 2 controls the connection and disconnection of the external water pipe and the sewer pipe 3.

[0038] Specifically, if Figure 1-4As shown, the lower flushing structure includes a constant pressure valve 4 arranged in the barrel body 1, the water inlet end 41 of the constant pressure valve 4 is connected to the above-mentioned sewer pipe 3, and the water outlet end 42 is connected to the flushing pipe 5. The lower end of the barrel body 1 has a water outlet cavity 12, and the water outlet cavity 12 is provided with a water outlet 12a. The water outlet cavity 12 has a mounting wall 12b arranged opposite the water outlet 12a, and the flushing pipe 5 has a water outlet portion 51 installed in the middle of the mounting wall 12b, and the mounting wall 12b is inclined from bottom to top toward the direction of the water outlet 12a. The water outlet portion 51 is located on the upper top wall 51a in the barrel body 1 and is inclined downward along the direction toward the water outlet cavity 12, and the outlet of the water outlet portion 51 is arranged opposite the water outlet 12a.

[0039] The external water inlet pipe is connected to the control valve 2, and the outlet end of the control valve 2 is connected to the sewer pipe 3. When the smart toilet is flushed, the control valve 2 is opened so that the tap water from the external water inlet pipe can enter the sewer pipe 3 and pass through the constant pressure valve 4. The constant pressure valve 4 can increase the pressure when the water pressure is too low and reduce the pressure when the water pressure is high, so as to keep the water pressure in the sewer pipe 3 constant, and then flush it out from the flush pipe 5 through the water outlet end 42 of the constant pressure valve 4, thereby achieving the purpose of water saving. Then, the water flow speed flushed out from the flush pipe 5 is also constant and the water pressure is relatively low. Therefore, the water flow direction of the flush pipe 5 needs to be set opposite to the water outlet 12a of the water outlet chamber 12 to ensure a better flushing effect. Therefore, under the barrel body 1, A mounting wall 12b is provided on the water outlet cavity 12 at the end, and the mounting wall 12b is arranged opposite to the water outlet 12a, and the mounting wall 12b is arranged tilted inward from bottom to top, and then the water outlet 51 of the flushing pipe 5 is installed in the middle of the mounting wall 12b. By the inclination of the mounting wall 12b and the inclination of the top wall 51a on the water outlet wall, the downward flushing angle of the tap water flushed out of the water outlet 51 is increased, so that the water flowing out from the outlet of the water outlet 51 can better be arranged opposite to the water outlet 12a, thereby improving the flushing effect. In addition, the setting of the mounting wall 12b makes it necessary for the water outlet 51 to be installed near the bottom of the barrel body 1, which can facilitate installation and save energy while also ensuring the flushing effect.

[0040] like Figure 4 and Figure 7 As shown, the outlet of the water outlet 51 is circular, the inner diameter of the water outlet 51 gradually decreases near the outlet, and the upper top wall 51a of the water outlet 51 is arc-shaped, and the upper top wall 51a is bent downward along its width direction.

[0041] like Figure 4-7As shown, the flushing pipe 5 includes a pipe body 52 and the above-mentioned water outlet 51. The water outlet 51 is tubular and threadedly connected to the pipe body 52. ​​One end of the water outlet 51 protrudes radially to form a limit stop edge 51b set in the water outlet cavity 12. At least two sealing gaskets 6 and a locking nut 7 are sleeved on the water outlet 51. One of the sealing gaskets 6 is located between the limit stop edge 51b and the installation wall 12b, and the other sealing gasket 6 is located between the locking nut 7 and the outer wall of the barrel body 1, and the locking nut 7 and the limit stop edge 51b cooperate to Multiple sealing gaskets 6 are compressed, and two sealing gaskets 6 are provided. The side walls of the two sealing gaskets 6 are arranged opposite to each other, and there are deformable walls 62 arranged inclined from the inside to the outside in a direction away from each other. The deformable walls 62 are respectively abutted against the inner and outer side walls of the barrel body 1. The inclination angle of the deformable wall 62 of the sealing gasket 6 located inside the barrel body 1 is smaller than the inclination angle of the deformable wall 62 of the sealing gasket 6 located outside the barrel body 1. The limit stop edge 51b and the sealing gasket 6 are both annular, and the outer diameter of the limit stop edge 51b is larger than the outer diameter of the sealing gasket 6 located inside the barrel body 1.

[0042] like Figure 6 and Figure 7 As shown, a deformation relief groove 51c is provided on the outer wall of the water outlet portion 51, and the deformation relief groove 51c is arranged near the upper top wall 51a. The sealing gasket 6 located in the water outlet chamber 12 is axially protruded on one side where it abuts against the limit stop edge 51b to form an annular sealing ring portion 63. Through the deformation of the sealing environmental protection 63 and the setting of the deformation relief groove 51c, the two ends of the sealing gasket 6 located in the water outlet chamber 12 are stably abutted against the limit stop edge 51b and the installation wall 12b respectively, thereby improving the sealing effect of the sealing gasket 6 and preventing the water in the water outlet chamber 12 from flowing out.

[0043] like Figure 1 and Figure 5 As shown, the outlet of the water outlet end 42 of the constant pressure valve 4 is set upward, and the barrel body 1 is provided with a limiting hole 13 outside the water outlet cavity 12 for the flushing pipe 5 to pass through. The flushing pipe 5 is connected to the water outlet end 42 of the constant pressure valve 4 and bends downward to pass through the limiting hole 13.
