Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a toilet flushing pipe and a toilet. Background Technology

[0002] Currently, to improve the production efficiency and yield rate of toilet ceramic bodies, and to facilitate high-pressure mold production, most toilets have eliminated the traditional flushing pipe design. For toilets that still require a flushing pipe, an interface is typically pre-installed in the toilet body, and the flushing pipe is then installed externally. There are currently two main methods for external flushing pipes on the market: one involves connecting the plastic flushing pipe and the drain base using several nuts, and the other involves adding a rubber tube at the flushing pipe joint to connect the flushing pipe and the drain base. Both existing solutions are not only structurally complex and inefficient to install, but also relatively expensive. Utility Model Content

[0003] The purpose of this utility model is to improve, at least to some extent, the problems existing in the prior art. To this end, this utility model provides a toilet flushing pipe and a toilet, so as to simplify the installation of the toilet flushing pipe, improve installation efficiency, and reduce installation costs to a certain extent.

[0004] To achieve the above objectives, this utility model provides a toilet flushing pipe, which includes a pipe body. The inlet end of the pipe body is provided with a platform stage and a receiving section. The receiving section is located inside the platform stage, and the diameter of the platform stage is smaller than the diameter of the receiving section.

[0005] Preferably, the inlet end further includes a limiting structure, which is at least partially located in the receiving section.

[0006] Preferably, there are two limiting structures, which are arranged symmetrically in the radial direction.

[0007] Preferably, the limiting structure includes a left limiting part, a right limiting part, and a lower limiting part, which together form a limiting groove.

[0008] Preferably, an annular protrusion is formed on the outer side of the stage along the axial direction, and a sealing ring is provided on the annular protrusion.

[0009] Preferably, the pipe body is made of plastic.

[0010] Preferably, the area of ​​the flow-through cross-section at the inlet end of the pipe body is larger than the area of ​​the flow-through cross-section at the outlet end.

[0011] Preferably, the flushing pipe further includes an outlet end connection assembly, which includes a rubber joint. One end of the rubber joint is connected to the outlet end of the pipe body, and the other end of the rubber joint is connected to the toilet body.

[0012] Preferably, the outlet end connection assembly includes a first hose clamp and a second hose clamp; the first hose clamp is adapted to reinforce the connection between the rubber joint and the outlet end of the pipe body, and the second hose clamp is adapted to reinforce the connection between the rubber joint and the toilet body.

[0013] This utility model also provides a toilet, including a toilet body, a water tank, and a flushing pipe. The water tank is provided with a drain valve, which includes a drain base and a locking member. The locking member includes an upper locking member, a lower locking member, and a bolt. At least one of the upper locking member and the lower locking member is threadedly connected to the bolt. The flushing pipe is a toilet flushing pipe as described in any of the above claims. The diameter of the receiving section is greater than the length of the lower locking member, and the diameter of the platform section is less than the length of the lower locking member, so as to allow the lower locking member to enter the receiving section from the inlet end of the pipe body in an inclined posture and to prevent the lower locking member from leaving the receiving section in a flat posture.

[0014] Preferably, the inlet end further includes a limiting structure, which is at least partially located in the receiving section. When the lower locking member is located in the receiving section in a flat position, the limiting structure is adapted to prevent the lower locking member from rotating.

[0015] Compared with the prior art, the toilet flushing pipe provided in this application embodiment, by setting a stepped section with a reduced diameter at the inlet end of the pipe body, can achieve a fixed connection with the drain valve base using the existing drain valve locking parts. Compared with the existing connection by nuts or rubber pipes, fewer parts are required, which can improve installation efficiency and reduce installation costs. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are preferred embodiments of the present utility model and should not be considered as excluding other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Reference Figure 1 , Figure 2 As shown, this utility model provides a toilet flushing pipe, which includes a pipe body 110. The inlet end of the pipe body 110 is provided with a platform stage 120 and a receiving section 130. In the axial direction of the pipe body 110, the receiving section is located inside the platform stage, and the diameter of the platform stage 120 is smaller than the diameter of the receiving section 130.

[0026] The toilet flushing pipe provided in this application includes a pipe body 110. In some preferred embodiments, the pipe body 110 is made of plastic. The pipe body 110 is a hollow tube with an inlet end as a water inlet and an outlet end as a water outlet. The inlet end of the pipe body 110 is provided with a step 120 and a receiving section 130, wherein the step 120 is closer to the end face of the inlet end than the receiving section 130. The step 120 is formed by extending the pipe body 110 radially inward. The receiving section 130 is located inside the step 120, that is, the receiving section 130 is closer to the midpoint of the pipe body 110 than the step 120. The diameter of the step 120 is smaller than the diameter of the receiving section 130.

[0027] The toilet flushing pipe provided in the embodiments of this application, such as Figure 3As shown, a pipe body 110 is adapted to connect a toilet tank 300 and a toilet body 200. The inlet end of the pipe body 110 is adapted to connect to the toilet tank 300, and the outlet end of the pipe body 110 is adapted to connect to the toilet body 200. Water from the toilet tank 300 flows into the toilet body 200 through the pipe body 110 for flushing. Specifically, the toilet flushing pipe provided in this embodiment is adapted to connect to a drain valve 400 within the tank 300. The drain valve 400, as a valve controlling the flow of water in the toilet, is installed at the drain outlet of the tank 300. Currently, drain valves 400 on the market have roughly the same structure and standard universal dimensions. Generally, as... Figure 4 As shown, the drain valve 400 includes a drain base 410 and a locking member 420. The locking member 420 includes an upper locking member 421, a lower locking member 422, and a bolt 423. The drain base 410 is provided with a limiting rib that cooperates with the upper locking member 421 to prevent the upper locking member 421 from disengaging from the drain base 410. In some preferred embodiments, the upper locking member 421 has a groove that can engage with the limiting rib to prevent the upper locking member 421 from shaking and to limit its vertical movement. At least one of the upper locking member 421 and the lower locking member 422 is threadedly connected to the bolt 423. In this embodiment, the upper locking member 421 has a through hole through which the bolt 423 passes, and the lower locking member 422 has a threaded through hole, and the lower locking member 422 is threadedly connected to the bolt 423. In other embodiments, both the upper locking member 421 and the lower locking member 422 are threadedly connected to the bolt 423. By rotating the bolt 423, the distance between the upper locking member 421 and the lower locking member 422 can be adjusted. By using the upper locking member 421 and the lower locking member 422 to abut against the bottom plate of the water tank 300 and the drain base 410, the drain valve 400 can be installed.

[0028] In this embodiment, the diameter of the platform stage 120 of the pipe body 110 is smaller than the length of the lower locking member 422, and the diameter of the receiving section 130 is larger than the length of the lower locking member 422. This allows the lower locking member 422 to be inserted into the pipe body 110 from the inlet end in an inclined position. The platform stage is adapted to prevent the lower locking member 422 from detaching from the pipe body 110 in a horizontal position. In this embodiment, "inclined position" means that the lower locking member 422 forms a certain angle with respect to the radial direction of the platform stage, and "horizontal position" means that the lower locking member 422 is parallel or approximately parallel to the radial direction of the platform stage. In actual installation, such as... Figure 5 and Figure 6As shown, the pipe body 110 and the drain valve 400 are respectively placed on the inner and outer sides of the water tank 300. The inlet end of the pipe body 110 is aligned with the drain outlet of the water tank 300. The lower locking member 422 of the drain valve 400 passes through the drain outlet of the water tank 300 and the platform stage 120 of the pipe body 110 in an inclined position to enter the receiving section 130 of the pipe body 110. The lower locking member 422 is adjusted to a flat position in the receiving section 130. The distance between the upper locking member 421 and the lower locking member 422 is adjusted by the bolt 423 so that the upper locking member 421 and the lower locking member 422 clamp the drain base 410, the bottom plate of the water tank 300 and the platform stage 120 together, thereby realizing the fixed connection of the toilet flushing pipe, the water tank 300 and the drain valve 400.

[0029] Compared with the prior art, the toilet flushing pipe provided in this application embodiment, by setting a stepped section with a reduced diameter at the inlet end of the pipe body 110, can be fixedly connected to the base of the drain valve 400 using the locking member 420 of the existing drain valve 400. Compared with the existing connection by nuts or by rubber pipes, fewer parts are required, which can improve installation efficiency and reduce installation costs.

[0030] In some preferred embodiments, the inlet end further includes a limiting structure 140, which is at least partially located within the receiving section 130. For example... Figure 2 As shown, a limiting structure 140 is provided in the receiving section to restrict the rotation of the lower locking member 422 within the receiving section. Preferably, the limiting structure 140 includes a left limiting part, a right limiting part, and a lower limiting part, which together form a limiting groove. Two limiting structures 140 are provided, and the two limiting structures 140 are arranged symmetrically in the radial direction.

[0031] In some preferred embodiments, such as Figure 2 As shown, an annular protrusion 150 is formed on the outer side of the stage 120 along the axial direction, and a sealing ring 160 is provided on the annular protrusion 150 to improve the sealing between the flushing pipe and the toilet tank 300 when the flushing pipe is installed in the toilet tank 300.

[0032] In some preferred embodiments, the cross-sectional area of ​​the inlet end of the pipe body 110 is larger than that of the cross-sectional area of ​​the outlet end. By setting the inlet end with a larger cross-sectional area, more water can be allowed to enter the flushing pipe. When the same volume of water is output from the outlet end with a smaller cross-sectional area, the water flow velocity will increase, thereby improving the flushing effect of the toilet.

[0033] In some preferred embodiments, the flushing pipe further includes an outlet end connection assembly, which includes a rubber joint 170. One end of the rubber joint 170 is connected to the outlet end of the pipe body 110, and the other end of the rubber joint 170 is connected to the toilet body 200. The outlet end connection assembly includes a first hose clamp 180 and a second hose clamp 190; the first hose clamp 180 is adapted to reinforce the connection between the rubber joint 170 and the outlet end of the pipe body 110, and the second hose clamp 190 is adapted to reinforce the connection between the rubber joint 170 and the toilet body 200.

[0034] This utility model also provides a toilet, including a toilet body 200, a water tank 300, and a flushing pipe. The water tank 300 is provided with a drain valve 400, which includes a drain base 410 and a locking member 420. The locking member 420 includes an upper locking member 421, a lower locking member 422, and a bolt 423. The upper locking member 421 and the lower locking member 422 are both threadedly connected to the bolt 423. The flushing pipe is a toilet flushing pipe as described in any of the above claims. The diameter of the platform section 120 is smaller than the length of the lower locking member 422, and the diameter of the receiving section 130 is larger than the length of the lower locking member 422.

[0035] like Figures 3-6 As shown, the drain valve 400, acting as a valve to control the flow of toilet water, is installed at the drain outlet of the water tank 300. The drain valve 400 includes a drain base 410 and a locking member 420. The locking member 420 includes an upper locking member 421, a lower locking member 422, and a bolt 423. The drain base 410 is provided with a limiting rib that cooperates with the upper locking member 421 to prevent the upper locking member 421 from disengaging from the drain base 410. In some preferred embodiments, the upper locking member 421 has a groove that can engage with the limiting rib to prevent the upper locking member from shaking and to limit its vertical movement. Function: At least one of the upper locking member 421 and the lower locking member 422 is threadedly connected to the bolt 423. In this embodiment, the upper locking member 421 has a through hole through which the bolt 423 passes, and the lower locking member 422 has a threaded through hole through which it is threadedly connected to the bolt 423. In other embodiments, both the upper locking member 421 and the lower locking member 422 are threadedly connected to the bolt 423. By rotating the bolt 423, the distance between the upper locking member 421 and the lower locking member 422 can be adjusted. In actual installation, such as... Figure 5 and Figure 6As shown, the pipe body 110 and the drain valve 400 are respectively placed on the inner and outer sides of the water tank 300. The inlet end of the pipe body 110 is aligned with the drain outlet of the water tank 300. The lower locking member 422 of the drain valve 400 passes through the drain outlet of the water tank 300 and the platform stage 120 of the pipe body 110 in an inclined position to enter the receiving section 130 of the pipe body 110. The lower locking member 422 is adjusted to a flat position in the receiving section 130. The distance between the upper locking member 421 and the lower locking member 422 is adjusted by the bolt 423 so that the upper locking member 421 and the lower locking member 422 clamp the drain base 410, the bottom plate of the water tank 300 and the platform stage 120 together, thereby realizing the fixed connection of the toilet flushing pipe, the water tank 300 and the drain valve 400.

[0036] In some preferred embodiments, the inlet end further includes a limiting structure 140, which is at least partially located within the receiving section 130. For example... Figure 2 As shown, a limiting structure 140 is provided in the receiving section to restrict the rotation of the lower locking member 422 within the receiving section. Preferably, the limiting structure 140 includes a left limiting part, a right limiting part, and a lower limiting part, which together form a limiting groove. Two limiting structures 140 are provided, and the two limiting structures 140 are arranged symmetrically in the radial direction.
