DETAILED DESCRIPTION

[0029] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Please refer to Figure 1-Figure 3 The utility model provides a floating drain core installed in the main body of the floor drain. Figure 3 The top layer of the floor drain body is equipped with a cover plate, and the bottom of the cover plate is equipped with a filter screen. The cover plate combined with the filter screen can effectively intercept large or fine impurities, and the floor drain core, as the core part of the floor drain, is responsible for drainage and blocking odor. The specific technical solution is described as follows:

[0031] like Figure 1 The main structure of the floating drain core includes a cover 1, a frame 2 and a holder 3, wherein the cover 1 is used to seal the floor drain and is movably arranged at the center of the frame 2. The outer side of the frame 2 is provided with an external thread, and the frame 2 can be screwed and assembled into the floor drain body by using the external thread. The holder 3 is installed at the bottom of the frame 2. The holder 3 is a detachable structure, and its outer edge can be fixed with the mortise and tenon at the bottom of the frame 2, and can be disassembled and replaced when necessary. A floating member 6 is provided between the holder 3 and the cover 1, wherein a guide member 7 is vertically provided at the center of the cover 1, and the guide member 7 can be inserted into the holder 3, and under the support of the floating member 6, specifically, the guide member 7 at the center of the lower part of the cover 1 is inserted into the central circular hole of the holder 3 and can move up and down. The holder 3 is installed at the lower part of the frame 2, and the outer edge is fixed with the end of the L-shaped hook body 41 at the lower part of the frame 2 by the mortise and tenon, and realizes vertical floating up and down.

[0032] In this embodiment, if Figure 4 and Figure 5The floating member 6 is a pair of mutually repelling permanent magnets, one of which is located on the cover 1 and the other is located on the holder 3. Specifically, a set of magnets is installed on the upper part of the holder 3 and the lower part of the cover 1, and they are arranged in a repelling state. Thus, the repelling magnetic force is used to make the cover 1 and the holder 3 suspended, and the cover 1 is in close contact with the frame 2. When water flows through, the cover 1 is compressed and breaks away from the frame 2, so that the sewage can be discharged from the floor drain.

[0033] On the basis of this embodiment, further, the tenon structure 5 and the base 3, the mortise structure 4 and the frame 2 are all made of plastic material and are integrally injection molded. Specifically, during its production process, the permanent magnet is encapsulated in the cover 1 and the frame 2, thereby effectively preventing the permanent magnet from being corroded by sewage and the problem of magnetic force weakening due to adsorption of iron slag during use.

[0034] In some embodiments, Figure 2 The outer edge of the card seat 3 is provided with a tenon structure 5 suitable for engaging with a plurality of mortise structures 4. Specifically, on one hand, the mortise structure 4 includes a hook body 41 and an upper tenon groove 43. The head end of the hook body 41 is integrally formed with the frame 2, and the tail end of the hook body 41 is provided with a lower arc slope 42. The middle part of the hook body 41 is provided with a mortise notch 45, and the upper tenon groove 43 is provided above the mortise notch 45. On the other hand, correspondingly, the tenon structure 5 includes a hanging foot 51, a lower tenon groove 52 and a tenon column 54, wherein the head end of the hanging foot 51 is integrally formed with the card seat 3, and the tail end of the hanging foot 51 is provided with an upper arc slope 53 matched with the upper tenon groove 43. A tenon column 54 is arranged at the bottom of the hanging foot 51. Since the tenon column 54 and the mortise and tenon notch 45 are both made of plastic and have good elasticity, the tenon column 54 can achieve interference fit with the mortise and tenon notch 45 and be snapped into the mortise and tenon notch 45, thereby improving the connection strength of the tenon column 54 and the mortise and tenon notch 45. At the same time, combined with the cooperation between the tenon groove and the arc slope, the risk of disengagement between the base 3 and the frame 2 can also be significantly reduced.

[0035] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
