Description

Technical Field

[0001] The utility model belongs to the technical field of drainage pipeline accessories and relates to a water trap with a magnetic one-way valve. Background Art

[0002] In building drainage pipes, water traps are indispensable accessories. They are often installed in the sewer pipes of sanitary appliances such as washbasins, vegetable sinks and toilets. Existing water traps rely on their own curved shape to form a water seal to prevent odors, harmful gases, bacteria, pathogens, reptiles, etc. in the pipe from entering the room. Existing water traps have the following deficiencies during use: 1. In some multi-story and high-rise residential buildings, the drainage volume of the drainage riser often gradually exceeds the water flow capacity of the drainage riser, resulting in the negative pressure in the drainage pipe exceeding the bearing capacity of the water seal of the water trap. A large amount of water in the water seal is pumped away by the negative pressure, thereby making the water trap lose its function of isolating odors; 2. Sanitary appliances such as washbasins have not been used for a long time, so that the water in the water trap cannot be compensated and the water seal fails due to long-term evaporation. Summary of the invention

[0003] The purpose of the utility model is to solve the above problems in the existing technology and propose a water trap with a magnetic one-way valve. The technical problem to be solved by the utility model is how to more effectively isolate harmful gases, viruses and other substances in the pipeline from entering the room.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A water trap with a magnetic one-way valve, including a water trap body, characterized in that a mounting seat is provided in the water trap body, the middle part of the mounting seat has a water passage connecting the two ends of the water trap body, a cover for closing the water passage is provided on the mounting seat, the cover can be connected to the mounting seat so as to be movably connected up and down, a magnetic component 1 is provided on the mounting seat, a magnetic component 2 which is attracted and cooperated with the magnetic component 1 is provided on the cover, and under the action of external force, the magnetic component 2 and the magnetic component 1 can be separated to open the cover.

[0006] The water trap with a magnetic one-way valve adds a magnetically controlled sealing structure inside the water trap body while retaining the traditional water seal. The sealing structure is in a normally closed state to separate the two ends of the water trap body, forming a double insurance with the water seal, thereby effectively preventing harmful gases, bacteria and viruses in the pipeline from entering the room.

[0007] In addition, when draining water, the water flow moves from the inlet end of the trap body to its outlet end. The magnetic attraction between the first magnetic member and the second magnetic member is overcome by the impact force of the water flow and the gravity of the water. The second magnetic member and the first magnetic member can be separated to open the cover, so that the two ends of the trap body are connected to allow normal drainage. After the drainage is completed, the cover resets under the action of the magnetic attraction, and the two ends of the trap body return to the non-connected state again. It is convenient to use and has high reliability.

[0008] In the above-mentioned trap with a magnetic suction one-way valve, both the first magnetic member and the second magnetic member are annular and arranged opposite to each other vertically. The annular first magnetic member and the annular second magnetic member enable the magnetic field to be concentrated and focused in the entire annular structure, which is beneficial to the mutual attraction between the first magnetic member and the second magnetic member. At the same time, the annular structure of the annular magnet allows the magnetic field to form a loop in the closed annular path, thereby reducing the space occupied by the first magnetic member and the second magnetic member. In addition, the distribution of the magnetic field in the annular paths of the first magnetic member and the second magnetic member is relatively uniform, which is beneficial to improving the stability of the magnetic field.

[0009] In the above-mentioned trap with a magnetic suction one-way valve, a sealing gasket is provided on the cover. The sealing gasket is inserted at the outlet of the water passing channel, and the second magnetic member is located on the outer peripheral side of the sealing gasket. By providing a sealing gasket inserted at the outlet of the water passing channel on the cover, the sealing performance when the cover is closed can be improved. At the same time, by arranging the second magnetic member on the outer peripheral side of the sealing gasket, a sealing effect can also be formed after the annular second magnetic member attracts the annular first magnetic member, thereby more effectively isolating harmful gases, viruses and other substances in the pipeline from entering the room.

[0010] In the above-mentioned trap with a magnetic suction one-way valve, the inner wall of the trap body has an annular positioning portion, and the mounting seat has a stepped portion that abuts against the positioning portion vertically. When in use, the user only needs to put the mounting seat into the inlet of the trap body from top to bottom, and the stepped portion on the mounting seat can automatically abut against the positioning portion of the trap body to form positioning, thus facilitating the disassembly and assembly of the mounting seat, and making the use and maintenance more convenient.

[0011] In the above-mentioned trap with a magnetic suction one-way valve, a plurality of protruding portions are provided on the outer side wall of the mounting seat. Guide columns are arranged vertically on the protruding portions. The guide columns are movably penetrated through the protruding portions up and down. The upper end of the guide column has a limiting portion that forms a limiting fit with the protruding portion, and the lower end of the guide column is fixedly connected to the cover. The cover is connected to the mounting seat through a plurality of guide columns so as to be movable up and down, making the movement of the cover more stable and accurate, so that the cover can be better opened or closed. At the same time, by providing a limiting portion at the upper end of the guide column, it can be avoided that the cover is separated from the mounting seat after moving downward.

[0012] In the above-mentioned water trap with a magnetic one-way valve, the positioning part and the raised part are arranged opposite to each other up and down, and the raised parts are arranged along the circumference of the mounting seat. By arranging the positioning part and the raised part opposite to each other up and down, the mounting seat as a whole has no convex part, which is convenient for disassembly, assembly and packaging of the mounting seat.

[0013] Compared with the prior art, the advantage of the water trap with a magnetic one-way valve is that a magnetically controlled sealing cover is added to the water trap body while retaining the traditional water seal. The sealing cover is in a normally closed state to separate the two ends of the water trap body, forming a double insurance with the water seal, thereby effectively preventing harmful gases, bacteria, viruses, etc. in the pipeline from entering the room.
