Description

Technical Field

[0001] The utility model belongs to the technical field of floor drains and relates to a floor drain core. Background Art

[0002] A floor drain refers to a drainage device installed on the ground. Its working principle is to utilize gravity and water seal principles to ensure smooth drainage while preventing odor and other harmful gases in the sewer from flowing back into the room.

[0003] Existing floor drains, for example, Chinese patent literature discloses a straight-through large-flow siphon floor drain compatible with washing machine drainage [patent number: 201620777735.X; application publication number: CN205822428U], a water outlet connected to a sewer pipe is provided below the main shell, a water screen is detachably connected to the inner wall of the main shell by a buckle, a frame is installed on the main shell, a grate is installed in the frame, a water hole is provided on the part of the water screen below the water inlet, a first through hole is opened in the middle of the water screen, a siphon member is connected to the inner wall of the first through hole through a plurality of ribs, a water diversion member for buffering and diverting is also provided on the top of the siphon member, and a washing machine connector can also be included, a second through hole is opened in the middle of the grate, and the washing machine connector is detachably connected to the first through hole in the middle of the water screen.

[0004] This type of floor drain can drain both the sewage from the washing machine and the sewage from the ground. However, the drainage channel for the washing machine sewage and the drainage channel for the ground sewage are the same. During the operation of the floor drain, the sewage from the washing machine and the sewage from the ground are discharged at the same time. The two types of sewage mix and interfere with each other, resulting in poor drainage of the floor drain. Summary of the invention

[0005] The utility model aims to solve the above problems in the prior art and proposes a floor drain core, which solves the technical problem of how to separate the sewage from the washing machine and the sewage on the ground so as to make the water flow from the floor drain smooth.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a floor drain core, including a cylindrical main body, the bottom of the main body has a first drain port, characterized in that a water outlet pipe is provided in the main body, the water outlet pipe includes a water inlet end and at least one second drain port running through the side of the main body, a flow channel connected to the first drain port is provided between the water outlet pipe and the main body, and the space inside the water outlet pipe is not connected to the flow channel.

[0007] The space inside the outlet pipe is not connected to the circulation channel, so that the floor drain core has two drainage channels. The sewage from the washing machine enters the outlet pipe through the water inlet end, and then is discharged toward the side of the main body through the second drainage port. The sewage on the ground is discharged through the circulation channel and the first drainage port. The sewage from the washing machine is discharged from the circumferential outside of the floor drain core, which can make the total flow cross-sectional area of ​​the drainage hole larger. The sewage from the washing machine has fewer impurities than the sewage on the ground, and the water flow is large, which can flush the inner wall of the pipe. The sewage on the ground is discharged from the circumferential inside of the floor drain core, so that the sewage from the washing machine and the sewage on the ground do not interfere with each other when draining. The sewage from the washing machine and the sewage on the ground are discharged separately, so that the water discharge from the floor drain is smooth.

[0008] In the above-mentioned floor drain core, the main body and the water outlet pipe are an integrated structure, and the main body and the water outlet pipe are integrally formed by injection molding. The integrated structure is easy to process and has a high degree of firmness, ensuring that the sewage from the washing machine and the sewage from the ground do not interfere with each other when draining.

[0009] In the above-mentioned floor drain core, the water inlet end of the water outlet pipe is protrudingly arranged outside the main body. This structure enables the water outlet pipe to be better connected to the external pipe.

[0010] In the above-mentioned floor drain core, the outer side wall at the bottom of the outlet pipe has a guide wall arranged obliquely downward and inward, and the guide wall is located directly above the first drain port. The guide wall plays a role of guiding flow, and the setting of the guide wall also increases the internal space of the flow channel near the first drain port, making it difficult to form negative pressure in the flow channel, so that the sewage on the ground can be better discharged.

[0011] In the above-mentioned floor drain core, the axial center line of the water inlet end of the water outlet pipe overlaps with the axial center line of the main body. This structure makes the arrangement of the water outlet pipe and the main body reasonable and makes the sewage discharge smooth.

[0012] In the above-mentioned floor drain core, the axial center line of the first drain port is perpendicular to the axial center line of the main body. This structure makes the structure of the water outlet pipe reasonable and enables the sewage to be discharged smoothly.

[0013] In the above-mentioned floor drain core, the water outlet pipe is T-shaped, and the number of the second drain outlets is two.

[0014] In the above-mentioned floor drain core, a sealing ring is sleeved on the end of the water inlet end of the water outlet pipe, the outer wall of the sealing ring has an extension extending downward, and the circumferential outer wall of the sealing ring has a plurality of sealing parts. This structure enables the sealing ring to have a better sealing effect, so that the sewage from the washing machine and the sewage on the ground do not interfere with each other.

[0015] In the above-mentioned floor drain core, the bottom of the main body has an anti-odor structure capable of blocking the first drain port. The anti-odor structure is a prior art, and the specific structure is not described in detail. The anti-odor structure plays a role in preventing odor and odor, and maintains indoor hygiene.

[0016] In the above-mentioned floor drain core, the floor drain includes a base and a panel with a through hole, the main body passes through the base, and the main body is fixedly connected to the base, the panel is embedded in the base, the water inlet end of the outlet pipe is located in the base or the water inlet end of the outlet pipe is protruding outside the panel, and the through hole is connected through the space inside the base, the circulation channel and the first drain port. This structure makes the installation position of the floor drain core reasonable, makes the floor drain structure reasonable, and the second drain port can flush the pipe wall of the pipe.

[0017] Compared with the prior art, the floor drain core provided by the utility model has the following advantages:

[0018] 1. The local leakage core allows the sewage of the washing machine to enter the outlet pipe through the water inlet end, and then be discharged toward the side of the main body through the second drain port. The number of the second drain ports is multiple and located on the side of the main body, which can effectively avoid the formation of negative pressure in the outlet pipe, so that the sewage of the washing machine can be better discharged through the outlet pipe.

[0019] 2. The space inside the outlet pipe of the local drain core is not connected with the flow channel, so that the sewage from the washing machine and the sewage on the ground do not interfere with each other during drainage, so that the local drain core can drain the sewage from the washing machine and the sewage on the ground separately, making the water out of the floor drain smooth.
