Description

Technical Field

[0001] The utility model relates to the technical field of floor drains, in particular to a double-filtering and anti-blocking floor drain device. Background Art

[0002] As an important interface between the drainage pipe system and the indoor floor, the floor drain can effectively discharge wastewater and dirt in the home, keep the home clean and hygienic, and prevent water accumulation on the floor, avoiding accidents such as slips. The filter design can block hair and debris to prevent them from flowing into the sewer pipe and causing blockage.

[0003] The filter mesh components commonly installed on floor drain products on the market are basically metal floor drains with small filter holes punched out of square or round shapes using metal sheets, or disposable plastic floor drains with small filter holes, such as the plastic floor drain described in patent CN201610954351.5.

[0004] However, the two existing products still have the following drawbacks: Metal floor drains are fixed in place, have a small drainage space, and feature a single filter screen that is easily clogged by hair and cannot be removed for cleaning, leaving significant blind spots. Disposable replacement floor drains, however, are lightweight, lack sufficient grip and barrier properties, and are easily washed away by water. Therefore, it is necessary to develop a floor drain device that can increase drainage volume, reduce the chance of drain screen clogging, and prevent the screen from being washed away, thereby fundamentally improving user comfort and service life.

[0009] Optionally, the shape of the first filter holes gradually increases from the center to the outside.

[0010] Optionally, the opening area of ​​the first filter hole is 1-3 times the opening area of ​​the second filter hole.

[0011] Optionally, a handle portion is provided on the central swirl portion.

This design allows the floor drain device to have a service life of more than 10 years.

[0018] (2) The present application designs the filter holes into a vortex arc fan shape, and the two groups of filter holes are distributed with a vortex tail, thereby simulating the vortex of water flow to guide water and drain water, generating water flow gravity, increasing the drainage volume, and the vortex water flow has the ability to self-clean the surface.

[0019] (3) In addition, a cylindrical handle is provided at the center of the anti-blocking filter body, which can be removed by hand for easy cleaning. The anti-blocking filter body can be cleaned and then recycled or replaced with a new one.

[0031] The present application realizes a dual filtering function by recessing a lower water chamber 11 on the floor drain base 1, placing the anti-blocking filter body 3 inside the lower water chamber 11, and the drainage panel 2 has its own filtering function, and improving the floor drain grid structure. Specifically, the floor drain grid structure is designed to be a central vortex part 31, a peripheral vortex part 32, and an edge part 33 arranged in sequence from the center to the periphery, and the central vortex part 31 is further designed to be a concave shape. Finally, through the arrangement design of the filter holes, a floor drain drainage device is obtained that can prevent the floor drain net from being washed away, increase the drainage volume, and reduce the probability of clogging of the floor drain net, thereby fundamentally improving the comfort and service life of the floor drain drainage device. This design makes the floor drain drainage device have a service life of more than 10 years.

[0032] As a further preferred solution, the size of the central vortex portion 31 is adapted to the size of the pipe opening of the sewer pipe, and the central vortex portion 31 is inserted into the pipe opening.

[0033] The recessed position of the central swirl portion 31 of this solution is adapted to the size of the pipe opening of the sewer pipe, and the two are assembled in a plug-in manner, which can play a certain limiting role and improve the installation stability of the anti-blocking filter body 3.

[0034] As a further preferred solution, the first filter hole 311 is a vortex arc fan-shaped filter hole, and the second filter hole 321 is a vortex arc fan-shaped filter hole. The first filter hole 311 and the second filter hole 321 have the same rotation direction.

[0035] This application designs the filter holes into a spiral arc fan shape, and the two groups of filter holes are distributed with a spiral tail, thereby simulating the vortex of water flow to guide and drain water, generate water flow gravity, increase the drainage volume, and the vortex water flow has the ability to self-clean the surface.

[0036] As a further preferred solution, the shape of the first filter holes 311 gradually increases from the center to the outside.

[0037] As a further preferred solution, the opening area of ​​the first filter hole 311 is 1-3 times the opening area of ​​the second filter hole 321 .

The inclined guide portion 331 quickly dissipates the water and traps any remaining hair and impurities on the peripheral edge portion 33. This continuous cycle prevents clogging of the filter body's primary drainage function, achieving optimal drainage. Furthermore, the support portion 332 has an increased edge height of 1mm, increasing the height space within the filter cavity and further enhancing the drainage efficiency of the radially trapezoidal filter holes on the guide portion.
