Description

Technical Field

[0001] The utility model belongs to the technical field of drainage facilities, and particularly relates to a floor drain core with a large diameter and a water seal isolation function. Background Art

[0002] Traditional floor drain designs mainly focus on drainage efficiency and preventing backflow, but there are deficiencies in achieving large-flow and rapid drainage while maintaining the water seal effect. Especially in places where a large amount of water needs to be handled, such as commercial kitchens, bath centers, etc., the drainage function of the floor drain core affects the hygiene of the kitchen and bathroom. It is often difficult to balance the water seal performance and drainage capacity of traditional floor drains. The existing floor drain core has a complex structure, which affects the drainage speed. Therefore, we propose a floor drain core with a large diameter and a water seal isolation function. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a floor drain core with a large diameter and a water seal isolation function. By setting a diversion pipe and a water seal device, the problems that the water seal performance and drainage capacity of traditional floor drains are often difficult to balance, and the existing floor drain core has a complex structure and affects the drainage speed are solved.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The utility model is a floor drain core with a large diameter and a water seal isolation function, including a diversion pipe. The bottom of the diversion pipe is connected and fixed with a water seal device. The diversion pipe is designed with a large diameter to ensure rapid drainage even when high-flow water enters, avoiding water accumulation and overflow. The angle of the diversion pipe is designed as a 30-degree inclined angle relative to the horizontal plane to promote the water flow to enter the water seal device more quickly. The water seal device is located below the diversion pipe and forms a water seal by using its internal structure to prevent sewer gas from backflowing, while not affecting the normal discharge of water flow. The inlet angle of the water seal device is consistent with that of the diversion pipe to smoothly guide the water flow and effectively form a water seal.

[0006] The utility model has the following beneficial effects:

[0007] 1. In this utility model, by providing a diversion pipe and a water seal, the diversion pipe is designed with a large diameter to ensure rapid drainage even when high-flow water enters, avoiding water accumulation and overflow. The angle of the diversion pipe is designed as a 30-degree inclined angle relative to the horizontal plane to facilitate the faster flow of water into the water seal. The water seal is located below the diversion pipe and forms a water seal using its internal structure to prevent the backflow of sewer gas without affecting the normal drainage of water. The inlet angle of the water seal is consistent with that of the diversion pipe to smoothly guide the water flow and effectively form a water seal. The floor drain collects the dirty water on the ground and enters the diversion pipe of the floor drain core. After entering the diversion pipe, the water enters the water seal under the action of gravity. The water seal is provided with a space for storing a certain amount of water. The water in the water seal is used to isolate the air between the sewer and the kitchen and bathroom, preventing the odor from the sewer from entering the kitchen and bathroom. The dirty water flowing into the diversion pipe enters the water seal under the action of gravity. The water seal is an open structure, and the dirty water entering the water seal will overflow from the overflow port and enter the sewer network.

[0008] Of course, it is not necessary for any product implementing this utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
