Description
Technical Field
[0001] The utility model relates to the field of floor drains, in particular to an odor-proof floor drain. Background Art
[0002] A Chinese patent document with publication number CN111945863A discloses an odor-proof floor drain, which is characterized in that it includes a face cover, a filter screen, a floor drain shell and an odor-proof core, the floor drain shell includes an upper shell and a drain pipe, the odor-proof core is arranged at the bottom end of the drain pipe, the odor-proof core includes a core shell, a flap, a seal and a reset mechanism, the flap is pivotally arranged at the water outlet of the core shell, the flap is fitted with the water outlet of the core shell under the action of the reset mechanism, the flap is sealed with the water outlet of the core shell by the seal, the seal includes a sealing body and a drainage ligament arranged on the outer periphery of the sealing body, and a water pressure groove with a notch opening outward is provided between the drainage ligament and the sealing body.
[0003] In the above solution, the floor drain shell and the deodorizing core are connected separately. Therefore, during long-term use, the deodorizing effect may be weakened due to loose connection. During installation, it is easy to have problems with alignment with the sewage pipe. Moreover, common floor drain shells are made of metal, which increases the cost and is easily eroded by water flow. Utility Model Content
[0004] The utility model aims to provide an odor-proof floor drain with low cost and long service life.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A deodorizing floor drain comprises a filtering section and a deodorizing section. The upper end of the filtering section forms a water inlet, and the deodorizing section forms a water outlet. The deodorizing section is connected to the lower end of the filtering section so that the water inlet and the water outlet are in communication. The deodorizing section is provided with a deodorizing structure. The characteristic is that the filtering section and the deodorizing section are integrally formed of a polymer.
[0007] By adopting the above technical solution, the one-piece filter section and the odor-proof section have no connection gaps. Compared with the traditional floor drain components connected by splicing, there is no water leakage problem due to loose connection. Since it is an integral structure, it is more convenient during the installation process. The one-piece molding of polymer material makes the floor drain have better mechanical properties so that it can withstand certain pressure and impact force. The one-piece molded floor drain will not have misalignment between components due to thermal expansion and contraction of the material or long-term water erosion, which greatly improves the service life of the floor drain. In addition, polymer is cheaper than metal materials, which undoubtedly reduces production costs.
[0008] The polymer is PVC or PPR.
[0009] By adopting the above technical solutions, both PVC and PPR materials have a long service life. They have good durability and can withstand long-term water impact, temperature changes and chemical corrosion. Compared with some traditional metal floor drains, polymer floor drains are not easy to rust and corrode, and can maintain good performance for many years or even longer.
[0010] It also includes a floor drain cover, the filter section has a top surface that matches the floor drain cover, the top surface of the filter section is provided with a plurality of positioning protrusions, and the floor drain cover can be placed on the top surface of the filter section and positioned by the positioning protrusions.
[0011] By adopting the above technical solution, the floor drain cover can be easily placed on the top surface of the filter section and positioned by the positioning protrusions, which makes the installation process extremely simple. The installation of the floor drain cover can be completed quickly without using complex tools or performing tedious operations. The setting of the positioning protrusions ensures that the floor drain cover can be accurately placed on the top surface of the filter section without any random movement. The floor drain cover can also provide a certain degree of protection for the filter section of the polymer material.
[0012] The height of the positioning protrusion is less than or equal to the thickness of the floor drain cover.
[0013] By adopting the above technical solution, when the height of the positioning protrusion is less than or equal to the thickness of the floor drain cover, after the floor drain cover is installed, the upper surface of the floor drain cover is basically flush with the ground or does not protrude from the floor drain cover, and no obvious protrusion is formed. This can ensure the flatness of the ground and prevent people from tripping when walking.
[0014] After the odor-proof floor drain is installed, the top surface of the odor-proof floor drain is lower than the ground, and the height difference between the ground and the top surface of the floor drain cover is greater than or equal to the height of the positioning protrusion.
[0015] By adopting the above technical solution, the top surface of the odor-proof floor drain is lower than the ground after installation, so that the odor-proof floor drain is buried under the ground and is not easily damaged. After installation, the floor drain cover can further protect the odor-proof floor drain.
[0016] The shape and size of the floor drain cover are adapted to the top surface of the filter section.
[0017] By adopting the above technical solution, the shape and size of the floor drain cover are adapted to the top surface of the filter section and can cover the top surface of the filter section, which can further prevent damage to the polymer filter section during use.
[0018] The top surface of the filter section is formed with a first recessed portion recessed downward, and a second recessed portion recessed downward from the first recessed portion, and the second recessed portion is used for placing the filter net.
[0019] By adopting the above technical solution, the first recessed portion can ensure smooth water flow, and the second recessed portion can facilitate the installation of the filter.
[0020] The top surface of the filter section is rectangular, and the four positioning protrusions are respectively arranged at the four corners of the top surface of the filter section. When the floor drain cover is placed on the top surface of the filter section, the four positioning protrusions abut against the four corners of the floor drain cover.
[0021] By adopting the above technical solution, the positioning protrusions at the four corners can effectively improve the stability of the floor drain cover. Since the positions of the positioning protrusions are clear, it is also very convenient for users to install the drain cover.
[0022] The four corners of the floor drain cover are respectively formed with a first abutting plane, and the positioning protrusion is formed with a second abutting plane. After installation, the first abutting plane and the second abutting plane abut against each other.
[0023] By adopting the above technical solution, the close fit between the planes makes it possible for the floor drain cover to have almost no room to move in the horizontal direction, ensuring that it is always stably placed in the correct position on the top surface of the filter section, which can effectively prevent the floor drain cover from being displaced during use.
[0024] The anti-odor structure consists of a counterweight block and an anti-odor plate. A mounting portion adapted to the anti-odor plate is formed in the anti-odor section, so that the anti-odor plate can be rotatably mounted on the mounting portion. The counterweight block is fixedly arranged at one end of the anti-odor plate, so that the anti-odor plate can close the water outlet of the anti-odor section in a natural state.
[0025] By adopting the above technical solution, the water outlet of the odor-proof section can be closed in a natural state through the counterweight block and the rotatable odor-proof plate, thereby effectively preventing odors, bacteria and pests in the sewer from flowing upward. The role of the counterweight block ensures that the odor-proof plate can fit tightly at the water outlet, forming a good sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solution of the present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings:
[0038] Example 1, refer to Figures 1 to 9 The odor-proof floor drain shown includes a filter section 1, an odor-proof section 2 and a floor drain cover 3. The upper end of the filter section 1 forms a water inlet 11, and the odor-proof section 2 forms a water outlet 21. The odor-proof section 2 is connected to the lower end of the filter section 1 and connects the water inlet 11 and the water outlet 21. The odor-proof section 2 is provided with an odor-proof structure, and the filter section 1 and the odor-proof section 2 are integrally formed using PVC or PPR.
[0039] The top surface of the filter section 1 is rectangular, and four positioning protrusions 12 are formed on the four corners of the rectangle to position and limit the floor drain cover 3. A drainage hole 31 is formed on the floor drain cover 3. After installation, the floor drain cover 3 can be placed on the top surface of the filter section 1, and the positioning protrusions 12 and the drainage holes 31 cooperate with each other to complete the positioning and fixation of the floor drain cover 1. The height of the positioning protrusions 12 is less than or equal to the thickness of the floor drain cover 3, and after the deodorizing floor drain is installed, the top surface of the deodorizing floor drain is lower than the ground, that is, the top surface of the filter section 1 is lower than the ground. Figure 9As shown, the height difference between the ground and the top surface of the floor drain cover 3 is greater than or equal to the height of the positioning protrusion 12, and the top surface of the filter section 1 is formed with a first recessed portion 13 that is recessed downward, and a second recessed portion 14 that is recessed downward from the first recessed portion 13. The above-mentioned four positioning protrusions 12 extend vertically upward from the four corners of the bottom wall of the first recessed portion 13 to achieve positioning and limiting of the floor drain cover 3. The connection between the first recessed portion 13 and the second recessed portion 14 is also formed with an arc-shaped transition section 15. The transition section 15 can better allow the water to flow from the first recessed portion 13 to the second recessed portion 14, and the bottom surfaces of the first recessed portion 13 and the second recessed portion 14 are inclined inward at a certain angle to prevent water accumulation, and the circumference of the first recessed portion 13 is greater than the circumference of the second recessed portion 14 to increase its drainage area and make the drainage efficiency higher. The second recessed portion 14 is circular, and two positioning columns 141 are formed in the second recessed portion 14, which can be used to fix the filter screen 4 to perform secondary filtration on the water flow.
[0040] The anti-odor structure consists of a counterweight 22 and an anti-odor plate 23. A mounting portion 24 adapted to the anti-odor plate 23 is formed in the anti-odor section 2, so that the anti-odor plate 23 can be rotatably mounted on the mounting portion 24. A clearance space 241 is also formed between the mounting portion 24 and the pipe wall of the water outlet 21. The counterweight 22 is fixedly arranged at one end of the anti-odor plate 23 and can rotate in the clearance space 241, so that the anti-odor plate 23 can close the water outlet 21 of the anti-odor section 2 in a natural state. A limiting notch 211 adapted to the anti-odor plate 23 is also formed on the pipe wall of the water outlet 21 to prevent the anti-odor plate 23 from excessive rotation.
[0041] During installation, it is only necessary to align the water outlet 21 of the odor-proof section 2 with the sewage pipe, bury the filter section 1 under the ground, and then position the floor drain cover 3 on the top surface of the filter section 1 through the four positioning protrusions 12 to prevent damage to the filter section 1 during use.
[0042] Example 2, refer to Figure 10 and Figure 11 As shown, the installation position and usage method of embodiment 2 are basically the same as those of embodiment 1, and will not be elaborated on here. The difference is that the four positioning protrusions 12 of embodiment 2 extend vertically upward from the four corners of the top surface of the filter section 1 and respectively form a first abutment plane 121, while the four corners of the floor drain cover 3 are respectively formed with a second abutment plane 32 corresponding to the first abutment plane 121, so that after the floor drain cover 3 is installed, the first abutment plane 121 and the second abutment plane 32 can abut against each other.
[0043] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the present patent.
