Description

Vertical comb tooth floor drain

Technical Field

The invention belongs to the technical field of drainage systems, and particularly relates to a vertical comb tooth floor drain.

Background

The floor drain is an important interface for connecting a drainage pipeline system with the indoor ground, and is used as an important part of a drainage system in a house. The existing floor drain is dirty in eyes of people, people pay attention to the floor drain rarely, hairs are always fully blocked on the surface of the floor drain after the floor drain is used for a period of time, the floor cleaning is influenced, the hairs are not easy to remove, and the hairs accumulated at a sewer bent pipe for a long time cause that the sewer is not smooth and even blocked.

In order to solve the above problems, CN201320820938.9 discloses a mesh-suspended hair-proof floor drain, which comprises a box body, a face cover with a leak slot, and a mesh-suspended frame capable of being embedded into the leak slot, wherein the face cover with the leak slot is characterized in that the leak slot comprises a main leak slot and a plurality of auxiliary leak slots, and a sealing plate is arranged at the water outlet of the cylinder body, which is vertically and horizontally intersected with the main leak slot and the auxiliary leak slots. The net hanging frame capable of being embedded into the leakage groove is characterized in that a gap is reserved between the net hanging frame and the leakage groove. Under the washing of water flow, the hair is automatically collected on the rack, and the rack can be taken out when the hair is cleaned, and the whole surface cover does not need to be taken out.

Although certain problem can be solved to above structure, it has a plurality of defects to exist, and one of them is that the rack of hanging in the embedding small opening is planar rack of hanging, and the centre clearance is great, and when hair fell along rivers, the rack of hanging can not effectively the separation all hairs, by the hair of separation also can break away from the rack because of rivers impact, the separation effect of rack of hanging is weakened. Secondly, when the rack is taken out by cleaning the hair, the whole surface cover does not need to be removed, but if the hair is too much, the hair is inconvenient to take out.

Disclosure of Invention

The invention aims to solve the existing problems and provide a vertical comb tooth floor drain.

The purpose of the invention can be realized by the following technical scheme: the vertical comb tooth floor drain is characterized by comprising a box body, a lifting device, pull rings, filter screens and rubber sheets, wherein a water drainage hole and vertical upward comb teeth are formed in the box body, the water drainage hole is located in the center of the box body, the comb teeth are located on the outer ring of the water drainage hole, the pull rings are arranged above the lifting device, the rubber sheets and the filter screens are arranged below the lifting device, the filter screens are located in the center of the lifting device, the rubber sheets are located on the outer ring of the filter screens, the filter screens correspond to pipe openings, the rubber sheets correspond to the comb teeth, small holes are formed in the rubber sheets and allow the comb teeth to be inserted into the small holes, the lifting device comprises an end cover above the lifting device, the pull rings are arranged above the end cover, the diameter of the end cover is larger than the water drainage hole, a water inlet is formed in the oblique side below the end cover.

The lifting device comprises a strip-shaped clamping hook and a supporting column, wherein a triangular blocking piece is arranged on the supporting column and connected with the filter screen, and the triangular blocking piece is connected with the rubber sheet and limits the rubber sheet to be positioned at the lower end part of the supporting column.

The comb tooth holes in the rubber sheet are smaller than the width of the comb teeth.

Compared with the prior art, the floor drain adopts the principle of rubber sheet contraction. The rubber sheet is placed at the lower end part of the supporting column of the lifting device and tightly attached to the comb teeth through the lifting device. The hair can be effectively blocked by the staggered comb teeth, and part of the hair which is not blocked by the comb teeth can also be blocked by the filter screen, so that the effect of comprehensively blocking the hair can be achieved. When the comb teeth have more hair and need to be cleaned, the hair on the comb teeth is pulled upwards by the pull ring, so that the hair on the comb teeth is moved to the plane above the rubber sheet by the attaching force and the pulling force of the rubber sheet. Meanwhile, the filter screen placed on the strip-shaped hook can be replaced. Compared with a plane net hanging rack, the rubber sheet can block sundries such as hair and the like, and a better effect is achieved. Finally, the rubber sheet and the filter screen of the device can be disassembled, assembled and replaced, and can be cleaned simply, quickly and effectively, and the structure is simple and easy to realize.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in figures 1-2, the invention comprises a box body 1, the box body 1 is cylindrical, a baffle plate is arranged above the box body, the center of the box body 1 is provided with a water discharge hole 1-1, the outer ring of the water discharge hole 1-1 is provided with comb teeth 1-3, the box body 1 is embedded by the comb teeth 1-3, and the comb teeth 1-3 are connected with the bottom of the box body 1. The box body 1 is also provided with outer side holes 1-2, and the outer side holes 1-2 are arranged on the cylindrical outer side wall and used for guiding accumulated water.

As shown in fig. 3-6, the upper part of the lifting device 2 comprises an end cover 3, the end cover 3 is larger than the diameter of the water discharge hole 1-1, a water inlet 2-1 is arranged on the oblique side below the end cover 3, a strip-shaped hook 2-2 is arranged below the lifting device 2, the strip-shaped hook 2-2 is connected with a filter screen 4, and the filter screen 4 is hooked by the strip-shaped hook 2-2 so as to be stable. The triangular separation blade 2-3 is arranged on the supporting column of the lifting device 2, the triangular separation blade 2-3 is connected with the rubber sheet 5, and when the rubber sheet 5 is placed on the comb teeth 1-3 and pushed downwards to the bottom of the box body 1, the triangular separation blade 2-3 plays a role in preventing the rubber sheet 5 from moving upwards. The upper end of the end cover 3 is provided with a pull ring, and the end cover above the lifting device 2 is fixed with the top of the strip-shaped hook 2-2. The filter screen 4 is arranged on the top of the strip-shaped hook 2-2. The rubber sheet 5 is provided with small holes 5-1, the small holes 5-1 are smaller than the width size of the comb teeth 1-3, and when the comb teeth 1-3 are inserted into the small holes 5-1, the small holes 5-1 can be elastically expanded.

The working principle is as follows: the rubber sheet 5 is arranged at the lower end part of the supporting column of the lifting device 2, and is pushed downwards to the bottom under the combined action of the supporting column of the lifting device 2 and the triangular separation blades 2-3 to be tightly attached to the comb teeth 1-3. The interlaced comb teeth 1-3 can effectively block hair, and part of the hair which is not blocked by the comb teeth 1-3 can also be blocked by the filter screen 4, so that the effect of comprehensively blocking hair can be achieved. When more hairs on the comb teeth 1-3 need to be cleaned, the hairs on the comb teeth 1-3 are moved to the plane above the rubber sheet 5 by the attaching force and the pulling force of the rubber sheet 5 through the pull ring pulling upwards. Meanwhile, the filter screen 4 arranged on the strip-shaped hook 2-2 can be replaced. Compared with a plane net hanging rack, the rubber sheet 5 can block sundries such as hair and the like, and has a better effect. The water inlet 2-1 is arranged on the oblique side below the end cover 3, when the lifting device 2 is inserted into the box body 1, the height of the comb teeth 1-3 is not lower than that of the upper surface of the end cover 3, so that the hairs can be ensured to firstly pass through the comb teeth 1-3 and enter the water inlet 2-1.
