Detailed ways

Hereinafter, the anti-odor and anti-clogging floor drain of the present invention will be described in detail in combination with exemplary embodiments.

In an exemplary embodiment of the present invention, the anti-odor and anti-clogging floor drain includes a casing, an inner cylinder, a filter element and a barrier assembly.

Wherein, the barrier assembly includes a sealing plate and an elastic member, the sealing plate is a circular plate with a diameter equal to or slightly smaller than the inner diameter of the inner cylinder and is arranged in the inner cylinder along the cross section of the inner cylinder, and the elastic member is arranged on the bottom of the inner cylinder and the sealing plate and connect the bottom of the inner cylinder with the sealing plate. When the elastic member is in a free state (that is, in a non-compressed state without force), the sealing plate is at the first position. Under the condition of being compressed under water pressure, the sealing plate is located at the second position. For example, the elastic member may be an elastic member such as a compressible spring. However, the utility model is not limited thereto, as long as the elastic member can enable the sealing plate to be in the second position when subjected to water pressure, and enable the sealing plate to be in the first position when not subjected to water pressure.

A drainage groove is arranged on the side wall of the inner cylinder, and the upper end of the drainage groove is higher than the second position and lower than the first position. The side wall of the shell is provided with a water outlet hole, and the lower end of the water outlet hole is higher than the upper end of the drainage groove. The outer casing is set on the outer side of the inner cylinder, and a channel communicating with the drainage groove and the water outlet hole is formed between the outer casing and the inner cylinder. The filter element is arranged above the inner cylinder to filter the water entering the inner cylinder.

In another exemplary embodiment of the present invention, on the basis of the above, the floor drain may further include a fixing piece for fixing the filter element on the inner cylinder, and the fixing piece is sleeved inside the casing. For example, the fixing member may be a threaded pressure ring.

In another exemplary embodiment of the present invention, on the basis of the above, the floor drain may further include a sealing rubber ring disposed on the circumference of the sealing plate, so as to realize sliding sealing of the sealing plate in the inner cylinder.

An exemplary embodiment of the present utility model will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a front sectional view of an anti-odor, anti-clogging floor drain according to an exemplary embodiment of the present invention.

Referring to FIG. 1 , in this exemplary embodiment, the anti-odor and anti-clogging floor drain includes a threaded pressure ring 1 , a filter plate 2 , a casing 3 , an inner cylinder 4 , a spring 5 and a sealing plate 6 .

Wherein, the sealing plate 6 is a circular plate having an inner diameter equal to that of the inner cylinder 4 , and the sealing plate 6 is arranged in the inner cylinder 4 along the cross section of the inner cylinder 4 . The spring 5 is arranged between the bottom of the inner cylinder 4 and the sealing plate 6 and connects the bottom of the inner cylinder 4 to the sealing plate 6 . As shown in Figure 1, under the situation that spring 5 is free state, sealing plate 6 is positioned at the first position (i.e. the dotted line place along the horizontal direction in Figure 1); In the compressed state, the sealing plate 6 is located at the second position (that is, the position of the sealing plate 6 in FIG. 1 ).

A drainage groove is provided on the side wall of the inner cylinder 4 , and the upper end of the drainage groove (ie the highest point of the drainage groove along the axial direction of the inner cylinder 4 ) is higher than the second position and lower than the first position. The side wall of the casing 3 is provided with a water outlet hole, and the lower end of the water outlet hole (ie the lowest point of the water outlet hole along the axial direction of the inner tube 4 ) is higher than the upper end of the drainage groove. The outer casing 3 is set on the outer side of the inner cylinder 4, and a passage connecting the drainage groove and the water outlet hole is formed between the outer casing 3 and the inner cylinder 4. For example, the contact section between the inner cylinder 4 and the outer shell 3 may be an overfit. The upper part of the housing 3 also has flange plates extending outward in its radial direction. The filter plate 2 is arranged above the inner cylinder 4 to filter the water entering the inner cylinder 4, thereby preventing foreign matter (such as hair, large particles of solid matter) from passing through the floor drain and finally entering the drain pipe. The threaded pressure ring 1 with external thread is screwed into the shell 3 with internal thread to fix the filter plate 2 on the inner cylinder 4 .

In this exemplary example, the threaded pressure ring 1, the shell 3, and the inner cylinder 4 can be made of corrosion-resistant materials such as stainless steel and plastic (for example, polytetrafluoroethylene); the filter plate 2 and the sealing plate 6 can be made of Stainless steel or polytetrafluoroethylene and other anti-corrosion materials are processed; the material of the spring 5 can be spring steel.

When using the anti-odor and anti-clogging floor drain of this exemplary embodiment, water enters the inner cylinder 4 through the filter plate 2 along the water flow direction shown in FIG. 1 . After the inner cylinder 4 accumulates water, the sealing plate 6 compresses the spring 5 due to the pressure of the accumulated water, so that the sealing plate 6 moves down from the first position along the inner wall of the inner cylinder 4 to the second position. In this way, the drainage groove of the inner cylinder 4 can be exposed, so that accumulated water can enter the channel formed between the inner cylinder 4 and the outer casing 3 through the drainage groove, and then flow into the drainage pipe through the outlet hole of the outer casing 3, thereby being discharged to the outside world. When there is no flowing water in the inner cylinder 4 or the accumulated water between the inner cylinder 4 and the outer shell 3 naturally evaporates to a height lower than the height of the first position (that is, h in FIG. 1 ), the sealing plate 6 is pushed by the spring 5 Move upwards from the second position to the first position along the inner wall of the inner cylinder 4, so that the drain groove of the inner cylinder 4 is sealed, thereby preventing the foul smell of the sewer from rising to the space (for example, the room) above the floor drain, thereby playing a role Anti-odor function. When there is accumulated water in the passage between the inner cylinder 4 and the outer shell 3, the accumulated water can prevent the odor of the sewer from rising to the space above the floor drain, and can prevent mosquitoes from entering the space above the floor drain through the floor drain. For example, mosquitoes can be sealed in the stagnant water at the drainpipe trap below the floor drain or in the stagnant water forming a channel between the inner tube 4 and the outer shell 3 .

The anti-odor and anti-blocking floor drain of the utility model can be directly installed at the mouth of the drain pipe, for example, it can be directly inserted into the drain pipe from the mouth of the drain pipe. In addition, the anti-odor and anti-clogging floor drain of the present invention can be designed in various models to be suitable for various types and sizes of drainage pipes.

To sum up, the anti-odor and anti-clogging floor drain of the present utility model has good anti-clogging, anti-odor and anti-mosquito effects no matter when there is water passing through the drainage system or when there is no water passing through the drainage system for a long time.

Although the present invention has been described above with reference to the drawings and exemplary embodiments, it should be apparent to those skilled in the art that various modifications can be made to the above embodiments without departing from the spirit and scope of the claims.
