[0023] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0024] Please refer to Figures 1-4 Fig. 1 shows a convenient type anti-backflow floor drain core, which comprises a main body 1, the main body 1 is provided with a rear cover 2 on one side, the rear cover 2 is rotatably provided with a sealing plate 3 for plugging the water outlet of the main body 1, the overall shape of the rear cover 2 is in an arc-shaped design, and the edge thereof is provided with a clamping portion 4 from top to bottom in a protruding manner, and the main body 1 is provided with a clamping groove 5 matched with the clamping portion 4.

[0025] The application is provided with a clamping portion at the edge of the rear cover, which is quickly assembled with the clamping groove during assembly, is easy to assemble and disassemble, greatly improves the assembly efficiency, and can be disassembled multiple times, so that the service life of the floor drain core is longer.

[0026] In the embodiment, the main body 1 is provided with a plurality of connecting portions 6, and the remaining positions between the connecting portions 6 and the main body 1 form the clamping grooves 5. The clamping grooves are formed by the connecting portions, so that the assembly is more firm and the service life is improved.

[0027] In the embodiment, the main body 1 is provided with a plurality of connecting portions 6, and the remaining positions between the connecting portions 6 and the main body 1 form the clamping grooves 5. The clamping grooves are formed by the connecting portions, so that the assembly is more firm and the service life is improved.

[0028] In the embodiment, the reinforcing plate 7 is provided with a positioning groove 8, the rear cover 2 is provided with an abutting portion 9 abutting against the reinforcing plate 7, and the abutting portion 9 is provided with a positioning protrusion 10 matched with the positioning groove 8. During assembly, the positioning protrusion plays a positioning role, so that the clamping portion and the clamping groove are completely matched.

[0029] In the embodiment, in the static state, the plane where the sealing plate 3 is located is perpendicular to the vertical direction of the rear cover 2. Then, the sealing plate can be flush with the lower end of the water outlet. In this way, the drainage is faster, the sealing performance is good, and the anti-backflow effect is better.

[0030] In the embodiment, the sealing plate 3 is provided with a first magnetic attraction unit 11 at the rotating position of the rear cover 2, and the rear cover 2 is provided with a second magnetic attraction unit 12 magnetically attracted to the first magnetic attraction unit 11. When the water pressure reaches the magnetic attraction pressure during drainage, the sealing plate is turned over to an open state, so as to drain water. After the water is drained to a certain extent, the sealing plate is reset to return to the closed state through the cooperation of the two magnetic attraction units.

[0031] In the embodiment, the sealing plate 3 is provided with a sealing ring 13.

[0032] In the embodiment, the cross section of the sealing ring 13 is designed in a U shape, and the inner wall of the main body 1 is provided with an abutting step 14 abutting against the sealing ring 13. Please refer to the accompanying drawings Figure 3 The sealing ring is designed in a U shape. In the closed state, the sealing ring is abutted by the abutting step. At this time, when water flow or gas enters the gap between the main body and the sealing plate, only the middle position of the U-shaped sealing ring can be filled. Therefore, the sealing ring will be more tightly attached, so that the sealing effect is better, and backflow into the inner cavity of the main body is impossible, greatly improving the anti-backflow effect.

[0033] The existing magnetic unit is assembled by means of adhesive bonding, which needs to be completed after the adhesive solidifies, so the efficiency is more low, and the magnetic unit cannot be disassembled multiple times subsequently. Therefore, the sealing plate 3 is provided with a containing cavity 15 for containing the first magnetic unit 11, and the main body 1 is provided with a positioning cavity for containing the second magnetic unit 12.

[0034] When assembling, the containing cavity is designed to match the shape of the first magnetic unit, and the first magnetic unit is inserted into the containing cavity, so that the use of adhesive can be cancelled, the assembly efficiency is improved, and the disassembly is further facilitated. Further referring to Figure 3 , the main body is designed to have a positioning cavity matching the shape of the second magnetic unit, and the magnetic unit is placed in the cavity to complete the installation.

[0035] In the embodiment, the containing cavity 15 is provided with a baffle 16 for positioning the first magnetic unit 11.

[0036] The above only describes the preferred embodiments of the present application, and is not intended to limit the scope of the present application. Other embodiments having the same or similar principles and basic structures as the present application are within the scope of the present application.
