Description

Technical Field

[0001] This utility model relates to the field of anti-clogging technology for floor drains, and in particular to an anti-clogging filter device for floor drains. Background Technology

[0002] A floor drain is a connection device between the floor and the drainage pipe, and its core functions are "rapid drainage, odor isolation, and debris interception." Its working principle can be summarized as follows: water flows through the grate into the inner core and is discharged along the drain pipe by gravity; the grate or filter simultaneously intercepts solid particles such as hair and sediment, reducing the risk of blockage. The odor-proof inner core isolates sewer gases through two methods: "water seal" or "mechanical seal." Water seal type: uses a U-shaped water trap to maintain a stable water column of ≥50mm, forming an airtight isolation layer; it fails when the water seal dries out and needs to be replenished periodically. Mechanical seal type: uses structures such as springs, magnets, silicone sheets, or gravity flaps; it automatically closes when there is no water and opens under water pressure during drainage, overcoming the disadvantage of water seals drying out easily, but it is susceptible to aging and jamming. Insect prevention and backflow prevention: A continuously effective water seal or mechanical seal can simultaneously prevent pests such as cockroaches and ants from crawling along the pipes and slow down sewage backflow during instantaneous drainage overload.

[0003] An existing anti-clogging filter device for floor drains can easily cause impurities to accumulate inside the drain over a long period of time when used by staff, thus affecting the drain's drainage performance and making it inconvenient for staff to clean the impurities trapped in the drain. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an anti-clogging filter device for floor drains.

[0005] This utility model is achieved by the following technical solution: an anti-clogging filter device for floor drains, including a floor drain frame, a garbage collection sleeve fixedly connected to the bottom of the floor drain frame, and a water leakage hole opened inside the garbage collection sleeve;

[0006] A fixed sleeve is fixedly connected to the bottom of the inner wall of the garbage collection sleeve. A lifting spring is fixedly connected to the bottom of the inner wall of the garbage collection sleeve. A lifting support is fixedly connected to the top of the lifting spring. A garbage collection plate is fixedly connected to the top of the lifting support. An installation support rod is fixedly connected to the top of the garbage collection plate. A drain cover is snapped onto the top of the drain frame. A lifting groove is provided inside the drain cover. A limiting post is fixedly connected to the bottom of the drain cover. A limiting slot is provided inside the drain frame.

[0007] Through the above technical solution, the two symmetrically distributed raised grooves inside the drain cover provide a leverage point for tool insertion, making it easy to pry the cover for deep cleaning. The bottom of the four limiting posts contacts the top of the garbage collection plate, forming a second limiting mechanism to prevent the cover from accidentally popping open and causing safety hazards.

[0008] As a further improvement to the above solution, the number of drainage holes is set to several, and the several drainage holes are equidistantly distributed around the garbage collection sleeve, with the lifting spring located inside the fixed sleeve.

[0009] Through the above technical solution, the fixed sleeve provides a vertical guide rail for the lifting column, ensuring that it rises and falls smoothly under the action of the lifting spring.

[0010] As a further improvement to the above solution, the lifting support is slidably connected inside the fixed sleeve, the garbage collection plate is inserted into the inner wall of the garbage collection sleeve, and the mounting support rod is inserted into the inside of the drain frame.

[0011] As a further improvement to the above solution, the number of mounting rods is set to four, and the four mounting rods are evenly distributed around the garbage collection plate as the center, and the mounting rods are inserted into the inside of the limiting slot.

[0012] Through the above technical solution, four circumferentially distributed installation support rods are inserted into the limiting slots of the drain frame, which not only fixes the position of the garbage collection plate, but also limits its excessive displacement, so that the garbage collection plate can be accurately reset after depressurization, keeping the filter surface horizontal and avoiding the dead corner of debris due to tilting.

[0013] As a further improvement to the above solution, the number of limiting posts is set to four, and the four limiting posts are evenly distributed around the mounting support rod, with the bottom of the limiting posts in contact with the top surface of the waste collection plate.

[0014] As a further improvement to the above solution, the number of the raised grooves is set to two, and the two raised grooves are symmetrically distributed on the left and right sides with the drain cover as the center, and the mounting support is located at the bottom of the drain cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model allows the drain cover and limiting post to be removed from the top of the garbage collection plate by pulling the lifting groove, which in turn lifts the mounting rod from inside the drain frame and the limiting groove. In conjunction with the extension and retraction of the lifting spring inside the fixing sleeve, the lifting post, garbage collection plate and mounting rod are lifted slightly from inside the drain frame, making it easier for staff to clean the impurities trapped on the garbage collection plate.

[0017] This invention creates a first physical barrier by setting up several drainage holes evenly distributed around the center inside the garbage collection sleeve. This allows water to flow through while intercepting impurities such as hair and mud. When the debris accumulates to a certain extent, the lifting spring is compressed and contracts, pushing the lifting support to move the garbage collection plate upward. This causes the accumulated debris to fall into the space below with the water flow, preventing complete blockage. This ensures normal drainage and achieves periodic self-cleaning, significantly reducing the frequency of manual dredging. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-4 An anti-clogging filter device for floor drains according to this embodiment includes a floor drain frame 1, a garbage collection sleeve 2 is fixedly connected to the bottom of the floor drain frame 1, and a water leakage hole 3 is opened inside the garbage collection sleeve 2.

[0027] A fixing sleeve 4 is fixedly connected to the bottom of the inner wall of the garbage collection sleeve 2. A lifting spring 5 is fixedly connected to the bottom of the inner wall of the garbage collection sleeve 2. A lifting support column 6 is fixedly connected to the top of the lifting spring 5. A garbage collection plate 7 is fixedly connected to the top of the lifting support column 6. An installation support rod 8 is fixedly connected to the top of the garbage collection plate 7. A drain cover 9 is snapped onto the top of the drain frame 1. A lifting groove 10 is opened inside the drain cover 9. A limit post 11 is fixedly connected to the bottom of the drain cover 9. The drain cover 9 and the limiting post 11 are pulled out from the top of the garbage collection plate 7 by pulling the lifting groove 10. This causes the installation support rod 8 to be lifted from the inside of the drain frame 1 and the limiting groove 12. In conjunction with the extension and retraction of the lifting spring 5 inside the fixing sleeve 4, the lifting support 6, the garbage collection plate 7 and the installation support rod 8 are lifted slightly from the inside of the drain frame 1, making it easier for staff to clean the impurities intercepted on the garbage collection plate 7.

[0028] The two symmetrically distributed raised grooves 10 inside the drain cover 9 provide a leverage point for inserting tools, making it easy to pry the cover for deep cleaning. The bottom of the four limiting posts 11 contacts the top of the garbage collection plate 7, forming a second limiting mechanism to prevent the cover from accidentally popping open and causing safety hazards.

[0029] The number of drainage holes 3 is set to several, and the drainage holes 3 are evenly distributed around the garbage collection sleeve 2. The lifting spring 5 is located inside the fixed sleeve 4.

[0030] The fixed sleeve 4 provides a vertical guide rail for the lifting column 6, ensuring that it rises and falls smoothly under the action of the lifting spring 5.

[0031] The support column 6 is slidably connected inside the fixed sleeve 4, the garbage collection plate 7 is inserted into the inner wall of the garbage collection sleeve 2, and the mounting rod 8 is inserted into the inside of the drain frame 1.

[0032] The number of mounting rods 8 is set to four. The four mounting rods 8 are evenly distributed around the garbage collection plate 7. The mounting rods 8 are inserted into the limit slot 12.

[0033] Four circumferentially distributed mounting rods 8 are inserted into the limiting slots 12 of the drain frame 1, which not only fixes the position of the garbage collection plate 7, but also limits its excessive displacement, so that the garbage collection plate 7 can be accurately reset after depressurization, keeping the filter surface horizontal and avoiding the accumulation of debris in dead corners due to tilting.

[0034] The number of limiting posts 11 is set to four. The four limiting posts 11 are evenly distributed around the installation support rod 8. The bottom of the limiting posts 11 contacts the top surface of the garbage collection plate 7. By setting several drainage holes 3 evenly distributed around the center inside the garbage collection sleeve 2, the first physical barrier is formed, allowing water to flow through while intercepting hair, mud and other impurities. When the debris accumulates to a certain extent, the lifting spring 5 is compressed and contracts, pushing the lifting support 6 to move the garbage collection plate 7 upward, so that the accumulated debris falls into the space below with the water flow, avoiding complete blockage. This ensures normal drainage and periodic self-cleaning, significantly reducing the frequency of manual dredging.

[0035] The number of lifting grooves 10 is set to two, and the two lifting grooves 10 are symmetrically distributed on the left and right sides with the drain cover 9 as the center. The mounting rod 8 is located at the bottom of the drain cover 9.

[0036] The implementation principle of an anti-clogging filter device for floor drains in this embodiment is as follows: When the lifting groove 10 is pulled out from the top of the garbage collection plate 7, the installation support rod 8 is lifted from the inside of the floor drain frame 1 and the limiting groove 12. With the extension and retraction of the lifting spring 5 inside the fixing sleeve 4, the lifting support 6, the garbage collection plate 7 and the installation support rod 8 are lifted slightly from the inside of the floor drain frame 1, which makes it convenient for staff to clean the impurities intercepted on the garbage collection plate 7. By setting a number of drainage holes 3 equidistantly distributed in the center inside the garbage collection sleeve 2, a first physical barrier is formed, which only allows water to flow through and intercepts impurities such as hair and mud. When the debris accumulates to a certain extent, the lifting spring 5 is compressed and contracts, pushing the lifting support 6 to move the garbage collection plate 7 upward, so that the accumulated debris falls into the space below with the water flow, avoiding complete blockage. This ensures normal drainage and periodic self-cleaning, significantly reducing the frequency of manual unclogging.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
