Description

A floor drain that is anti-blocking and easy to drain and clean Technical Field

[0001] The utility model relates to the technical field of floor drains, in particular to a floor drain which is anti-blocking and convenient for drainage and cleaning. Background Art

[0002] The floor drain is an important interface between the drainage pipe system and the indoor floor. As an important component of the drainage system in a house, its performance directly affects the quality of indoor air and the physical and mental health of the residents. It is very important for the hygiene and odor control of the kitchen and bathroom.

[0003] The existing odor-proof floor drains include spring self-closing type, magnetic levitation type, deep water seal type and silicone closed type. The spring self-closing odor-proof floor drain is prone to blockage after long-term use and is very difficult to clean after being blocked. Not only is the odor-proof effect greatly reduced, but the blocked objects are also prone to stink. The magnetic levitation odor-proof floor drain loses its magnetic resetting effect after a long time and does not close after resetting, thus losing its odor-proof effect. In addition, the magnetic levitation odor-proof floor drain is prone to blockage due to objects falling into the pipe. The existing deep water seal type has a narrow channel and a relatively small volume, which makes the water discharge slow and prone to overflow. The silicone closed type is prone to odor backflow due to blockage, aging and loose closure. In addition, the existing side drainage floor drain is slow to drain because it is close to the water level in the pipe. Therefore, it is very necessary to improve the above-mentioned odor-proof floor drains.

They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0028] The present invention will be further described with reference to the accompanying drawings.

[0029] Example 1:

[0030] Please refer to Figures 1 to 3. The present invention provides a floor drain that is anti-blocking and easy to drain and clean, including a floor drain body 1, an odor-proof drainage chamber 2, and a cover plate 3. The floor drain body 1 includes a base 11 and an upper cover 12. The base 11 and the upper cover 12 are fixedly connected by matching screws and screw holes, and a sealing ring 19 is provided at the connection between the two; an upper drainage groove 4 is provided in the upper cover 12, a lower drainage groove 5 and a drainage hole 6 are provided in the base 11, a drainage pipe 7 is provided on the base 11, and the drainage hole 6 is provided in the drainage pipe 7. The drainage pipe 7 in this embodiment is provided on the side of the base 11.

[0031] The cover plate 3 is installed in the upper drainage trough 4, and there is a drainage gap between the two. There are two lower drainage grooves 5 in the base 11, and they are symmetrically arranged on both sides of the drainage hole 6. The odor-proof drainage chamber 2 is detachably installed in the lower drainage trough 5, and a drainage cavity 9 communicating with the drainage hole 6 is formed between the side and the lower drainage trough 5. Specifically, a mounting boss 13 is provided in the lower drainage trough 5 in the base 11, and the odor-proof drainage chamber 2 is provided with abutting boss 14 that can form abutment with the mounting boss 13, thereby realizing the detachable installation of the odor-proof drainage chamber 2. In order to ensure the sealing of the connection, a sealing ring 19 is provided between the abutting boss 14 and the side of the lower drainage trough 5 of the base 11; the odor-proof drainage chamber 2 is provided with a plurality of drain holes 10 connecting the upper drainage trough 4 and the drainage cavity 9. The lower end of the odor-proof drainage chamber 2 is in the lower drainage trough 5 and has a distance from the bottom of the lower drainage trough 5. In order to save cost, the odor-proof drainage chamber 2 is preferably made of plastic material.

[0032] As shown in Figure 4, during drainage, the drainage passes through the upper drainage groove 4 and the lower water hole 10 into the lower drainage groove 5, and then is discharged through the drainage cavity 9 and the drainage hole 6. The drainage rises in the lower drainage groove 5 and the drainage cavity 9. When the water level is higher than the connection between the lower drainage groove 5 and the drainage hole 6, the liquid will be drained from the drainage hole 6 under the action of its own gravity. The water flow continues and forms a seal at the connection between the lower drainage groove 5 and the drainage hole 6. Once the water flows away, a local vacuum appears at the connection between the lower drainage groove 5 and the drainage hole 6, and the liquid in the drainage cavity 9 will be continuously pressed into the drainage cavity 9 under the action of atmospheric pressure. In the drainage hole 6, a bell-shaped siphon principle is formed to achieve rapid drainage; the lower drainage trough 5 can store water after drainage is completed, and the lower end of the odor-proof drainage chamber 2 is in the lower drainage trough 5, thereby realizing a water seal and achieving an odor-proof effect. In the drainage process, large debris will be blocked at the cover plate 3, and the partitions between the multiple drain holes 10 in the odor-proof drainage chamber 2 can block debris such as hair. At the same time, some debris will settle at the bottom of the lower drainage trough 5, and the odor-proof drainage chamber 2 is a detachable connection method, which is convenient for removal and cleaning of debris in the lower drainage trough 5, effectively avoiding blockage.

[0033] In order to further speed up the drainage speed, the deodorizing drainage chamber 2 is provided with a drainage arch 15 at the connection between the lower drainage groove 5 and the drainage hole 6.

[0034] In order to facilitate the removal and placement of the deodorizing drainage chamber 2 for disassembly and cleaning, a disassembly and assembly gripping protrusion 16 is provided at the drainage arch 15 of the deodorizing drainage chamber 2 .

[0035] Furthermore, a snap protrusion 17 is provided on the side of the deodorizing drainage chamber 2, and a snap groove 18 corresponding to the snap protrusion 17 is provided on the side of the lower drainage trough 5, which not only facilitates the snap connection of the deodorizing drainage chamber 2, but also improves its connection stability.

[0036] Furthermore, a cover plate rotating member 20 is installed in the upper cover 12, and a matching fixing column 23 and a fixing hole 24 are provided between the bottom of the cover plate rotating member 20 and the upper cover 12. The cover plate rotating member 20 is in contact with the cover plate 3 and is provided with a rotating column 21 at both ends thereof, and a rotating groove 22 corresponding to the rotating column 21 is provided on the cover plate 3; when the cover plate 3 needs to be removed for cleaning, a force is applied downward on one end of the cover plate 3, and the cover plate 3 is rotated and tilted through the rotating column 21, thereby facilitating the removal of the cover plate 3. The corresponding cooperation between the rotating column 21 and the rotating groove 22 can also play a positioning role in the placement of the cover plate 3.

[0037] Example 2:

[0038] Please refer to Figures 5 to 7. The principle and structure of this embodiment are basically the same as those of the embodiment. The difference is that the drain pipe 7 is set vertically downward on the base 11.
