[0002] Traditional drainage pipe floor drains primarily consist of a drain body with a water guide hole and a drain cover with a central hole, with the drain pipe connected to the central hole of the drain cover. Currently, to provide such floor drains with insect and odor-proofing functions, a common practice is to install an insect and odor-proofing device in the central hole of the drain cover via an adapter. This means that the insect and odor-proofing device is directly fixed to the drain cover. While this installation method allows for the installation of the insect and odor-proofing device, it also limits the installation depth of the device, making it impossible to adapt the installation to different drain depths. Consequently, many drainage pipe floor drains still cannot be installed with an insect and odor-proofing device, causing significant problems in practical use. Summary of the Invention

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", "both ends", etc., indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0023] like Figure 1-2 As shown, a drainage pipe floor drain with an anti-insect and anti-odor device with adjustable height comprises a floor drain cover 1 and an anti-insect and anti-odor device 2.

[0024] A center hole 11 is provided at the center of the floor drain cover 1 , and the anti-insect and anti-odor device 2 is installed in the center hole 11 through an adapter 3 .

[0025] The adapter 3 includes a connector body 31 and a fixing nut 32. The connector body 31 is provided with a stop flange 311 on the upper end surface of the floor drain cover 1, and the lower end of the connector body 311 passes through the center hole 11 of the floor drain cover 1 and is connected to the nut 32.

[0026] The connector 4 for the drain pipe is connected to the top of the connector body 31. The connector 4 for the drain pipe includes at least one water inlet end 41 and one water outlet end 42. Each water inlet end 41 is connected to a drain pipe, and the water outlet end 42 is connected to the top of the connector body 31. In this figure, the connector 4 for the drain pipe is provided with two water inlets 41 and one outlet end 42. In practice, only one water inlet end 41 or more water inlet ends 41 may be provided as needed to meet the drainage needs of a single or multiple drain pipes.

[0027] For the convenience of processing and assembly, the above joint body 31 and the water outlet end 42 of the connection joint 4 of the drain pipe can be set as an integral structure, and this figure adopts this structure. In practice, of course, the two can also be set as a separate combined structure, and its structure is as follows Figure 3 shown.

[0028] The adapter 3 is connected to the anti-insect and anti-odor device 2 via a lifting and adjusting mechanism 5. The lifting and adjusting mechanism 5 includes a connecting bushing 51 and a lifting rod 52.

[0029] The outer wall of the connecting bushing 51 is threadedly connected or tightly fitted to the lower part of the inner hole 312 of the joint body 31. The inner wall of the connecting bushing 51 is provided with an upper connecting hole 511 connected to the upper end of the lifting rod 52. The center of the lifting rod 52 is provided with a water guide hole 521 that runs vertically through it for drainage of the drain pipe.

[0030] The insect and odor-proofing device 2 includes a valve body 21 having a drain hole 211 extending vertically therethrough. A mounting post 212 is located at the center of the upper opening of the drain hole 211. The mounting post 212 is connected to the valve body 21 via a plurality of connecting arms 213. A lower connecting hole 2121 is located at the center of the mounting post 212, which is connected to the lower end of the lifting rod 52. An openable and closable sealing cover 23 with a reset mechanism 22 is located at the bottom of the drain hole 211.

[0031] At least one of the upper connecting hole 511 and the lower connecting hole 2121 is threadedly or slidably connected to the lifting rod 52. In this illustration, the upper connecting hole 511 is threadedly connected to the upper end of the lifting rod 52, and the lower connecting hole 2121 is also threadedly connected to the lower end of the lifting rod 52, so that the position of the lifting rod 52 relative to both holes can be adjusted. In practice, other structures may also be adopted, such as the upper connecting hole 511 being fixedly connected to the upper end of the lifting rod 52, and the lower connecting hole 2121 being threadedly or slidably connected to the lower end of the lifting rod 52, so that the lifting rod 52 can only be adjusted relative to the lower connecting hole 2121; or the upper connecting hole 511 being threadedly or slidably connected to the upper end of the lifting rod 52, and the lower connecting hole 2121 being fixedly connected to the lower end of the lifting rod 52, so that the lifting rod 52 can only be adjusted relative to the upper connecting hole 511; or the upper connecting hole 511 being slidably connected to the upper end of the lifting rod 52, and the lower connecting hole 2121 being slidably connected to the lower end of the lifting rod 52, so that the lifting rod 52 can be adjusted relative to both the upper connecting hole 511 and the lower connecting hole 2121. All of the above structures can achieve the need to adjust the installation height of the insect-proof and odor-proof device 2, and any of them may be selected in practice.

[0032] During use, the height of the lifting rod 52 relative to the floor drain cover 1 can be adjusted by rotating or sliding the lifting rod 52 relative to the upper connecting hole 511 in the connecting bushing 51, thereby adjusting the height of the insect and odor-proof device 2 at the lower end of the lifting rod 52 relative to the floor drain cover 1, thereby meeting the actual installation height requirements of the insect and odor-proof device 2. Alternatively, the height of the insect and odor-proof device 2 relative to the lifting rod 52 can be adjusted by rotating or sliding the lower connecting hole 2121 on the mounting post 212 with the thread of the lifting rod 52, thereby adjusting the height of the insect and odor-proof device 2 at the lower end of the lifting rod 52 relative to the floor drain cover 1, thereby meeting the actual installation height requirements of the insect and odor-proof device 2.

[0033] Here, by adjusting the lifting rod 52 relative to the lower connecting hole 2121, the water guide hole 521 in the lifting rod 52 can be adjusted relative to the outlet of the insect-proof and odor-proof device 2 at the same time, so that it penetrates deeper into the insect-proof and odor-proof device 2 and shortens the distance with the sealing cover 23. When the drain pipe is draining, the sealing cover 23 can be quickly opened for rapid drainage, which can effectively avoid overflow caused by untimely opening.

[0034] Here, in order to take into account the needs of ground drainage, the cover plate of the floor drain cover 1 is densely covered with drainage holes or a plurality of support protrusions 12 are arranged downward on the periphery. The support protrusions 12 are spaced apart along the circumference, and the gaps between adjacent support protrusions 12 form a water guide groove 13 for ground drainage. A gap is left between the insect-proof and odor-proof device 2 and the floor drain cover 1 to form an internal water inlet 6. During use, sewage on the ground passes through the drainage holes or the water guide groove 13 and enters the drainage hole 211 of the insect-proof and odor-proof device 2 through the internal water inlet 6, and is drained by opening the sealing cover 23, so that the floor drain has the dual functions of drain pipe drainage and ground drainage. In this figure, the peripheral support protrusion 12 structure is adopted. This structural setting allows the entire floor drain cover 1 to be lifted without having to adapt to the existing floor drain body, and can meet the needs of modifying drain pipe floor drains of different sizes.

[0035] Here, to ensure the sealed connection between the insect-proof and odor-proof device 2 and the drain hole of the floor drain body or the pipe mouth of the drain pipe after installation, the top of the valve body 21 of the insect-proof and odor-proof device extends outward to form a connecting outer circle 214. The outer wall of the valve body 21 is provided with a sealing member below the connecting outer circle 214. The sealing member is inserted into the drain hole of the floor drain body or the pipe mouth of the drain pipe during assembly to achieve a sealed connection. The sealing member includes a sealing body 7a, the top of the sealing body 7a is provided with a connecting outer edge 7a1 facing outward. The connecting outer edge 7a1 is sealed against the bottom of the connecting outer circle 214 of the valve body 21. The outer wall of the sealing body 7a is provided with a plurality of umbrella skirt structures 7a2 spaced apart in an upper and lower manner to meet the sealing connection requirements of different hole diameters or pipe diameters. In this figure, three umbrella skirts 7a2 are provided, but in practice, more can be provided as needed.

[0036] Considering ease of assembly and processing requirements, the valve body 21 of the insect and odor-proof device 2 is composed of an upper valve body 21a, a middle connecting member 21b, and a lower valve body 21c. The upper portion of the middle connecting member 21b is fixedly connected to the upper valve body 21a, and the lower portion of the middle connecting member 21b is fixedly connected to the lower valve body 21c. During processing, these three components are separately processed and then assembled, which effectively simplifies the mold structure and reduces production costs.

[0037] Here, there are various structures of the sealing cover 23 and the reset structure 22 in the above structure.

[0038] In this figure, the sealing cover 23 is a single-sided rotating opening structure, one side of the sealing cover 23 is movably hinged to the valve body 21, and a reset structure 22 is provided between the bottom of the sealing cover 23 and the valve body 21 to seal the drain hole 211 of the sealing cover 23.

[0039] And as Figure 4 As shown, the sealing cover 23 is an up and down lifting structure, and a guide rod 231 is provided at the center of the sealing cover 23. The guide rod 231 is movably inserted into a mounting seat 232. The mounting seat 232 is connected to the valve body 21 through a plurality of support arms 2321. A reset structure 22 is provided in the mounting seat 232 so that the sealing cover 23 always has an upward reset force.

[0040] The reset structure 22 is a magnetic reset structure or a spring reset structure, and all floor drain reset structures currently on the market are applicable.

[0041] In summary, the drainage pipe floor drain designed by the present invention has an adapter 3 on which is connected to the anti-insect and anti-odor device 2 through a lifting and adjusting mechanism 5, so that the installation height of the anti-insect and anti-odor device 2 can be adaptively adjusted according to the specification depth of the actual floor drain to meet the actual installation needs, and has the characteristics of simple and practical structure.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent change or modification made to the above embodiment based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
