Description

Technical Field

[0001] The utility model relates to the field of bathroom and kitchen equipment, in particular to a water-sealed floor drain core. Background Art

[0002] Floor drains are a crucial component of drainage systems in residential and commercial buildings, and their performance directly impacts indoor air quality and sanitation. While existing floor drain cores address basic drainage needs to a certain extent, they still present numerous challenges in practical applications, requiring urgent improvement and optimization.

[0003] 1. Gas overflow problem:

[0004] Existing floor drain cores generally lack an effective water seal design, allowing gas inside the drain pipe to escape through the drain pipe and out of the drain core, emitting unpleasant odors. This phenomenon not only affects the comfort of the living environment but also poses a potential threat to human health.

[0005] 2. Small drainage volume and easy to clog:

[0006] The existing floor drain core has the problem of small drainage capacity and easy clogging in design. Specifically:

[0007] Spring floor drain core: The spring structure is prone to rust and has greater resistance, making drainage difficult.

[0008] Rubber floor drain core: The rubber-enclosed structure has a small displacement and can easily lead to drainage difficulties.

[0009] Floor drain core with magnetic adsorption structure: easily absorbs metal impurities such as iron, affecting the sealing effect and causing poor drainage.

[0010] Gravity structure floor drain core: its counterweight block occupies the bottom opening space of the floor drain core, resulting in a small floor drain discharge volume, which in turn easily leads to difficulties in drainage.

[0011] In view of the above problems, the present inventors provide a better solution. Utility Model Content

[0012] The purpose of the utility model is to provide a water-sealed floor drain core, which can prevent insects and isolate odors through the water-sealing principle and has a simple structure.

[0013] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0014] A water-sealed floor drain core is integrally formed and comprises a water inlet, a water outlet and an overflow, wherein the water outlet is located at the central axis of the overflow, the overflow is located higher than the water outlet and simultaneously constitutes a water-sealed structure.

[0015] The water-sealed floor drain core employing the aforementioned structure utilizes the water level difference between the overflow and outlet to form a water seal, achieving insect and odor-proofing effects. Because the outlet is located at the central axis of the overflow, water flows evenly around the perimeter, resulting in high drainage capacity and resistance to clogging. This water-sealed floor drain core requires only a single component, resulting in a simple structure and low costs in both manufacturing and materials.

[0016] Preferably, the water-sealed floor drain core includes a water downflow portion and a water storage cup, and the water downflow portion and the water storage cup are fixed together by ribs arranged at intervals. The water downflow portion includes the water inlet and the water outlet, and the cross-sectional area of the water inlet is larger than that of the water outlet. The water storage cup includes the overflow, and the cross-sectional area of the overflow is larger than that of the water outlet. Because the cross-sectional area of the water downflow portion is larger than that of the water outlet, the water is pressurized as it flows through the water inlet and out of the water outlet, resulting in a greater impact force. This prevents dirt in the pipe from settling in the water storage cup, which helps maintain the continuous patency of the water storage cup.

[0017] Preferably, the water storage cup is a cup-shaped body with a closed lower end, an open upper end, a wide top and a narrow bottom, and an inclined peripheral wall. This wide top and narrow bottom structure allows the overflow port to have a larger opening relative to the outlet, resulting in greater and smoother drainage. Furthermore, even with a small amount of water stored in the water storage cup, it can still meet the requirements of insect prevention and odor isolation.

[0018] Preferably, the water discharge part is a rotating body similar to a funnel shape.

[0019] Preferably, the water inlet and the water outlet are connected by a rounded transition.

[0020] Preferably, the water inlet is provided with an external thread, which is spirally connected to the floor drain.

[0021] Preferably, a sealing ring is provided on the outside of the water inlet to seal with the floor drain. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following is a brief introduction to the drawings required for use in the embodiments. It should be understood that the following drawings only show certain embodiments of the present invention and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without creative work.

[0027] like Figures 1 to 4 As shown, a water-sealed floor drain core is integrally formed and includes a water discharge portion 1 and a water storage cup 2, wherein the water discharge portion 1 and the water storage cup 2 are fixed by ribs 3 arranged at intervals.

[0028] The drain unit 1 is a funnel-shaped rotating body. It includes an inlet 11 and an outlet 12, with the inlet 11 having a larger cross-sectional area than the outlet 12. The water storage cup 2 includes an overflow port 21, with the overflow port 21 also having a larger cross-sectional area than the outlet 12. The inlet 11 and outlet 12 are connected by a rounded transition.

[0029] The water storage cup 2 is a cup-shaped body with a closed lower end, an open upper end, a wide upper end and a narrow lower end, and an inclined peripheral wall. The water outlet 2 is located at the central axis of the overflow port 21. The overflow port 3 is located higher than the water outlet 2 and forms a water seal structure with the water outlet 2.

[0030] As a preferred embodiment, the floor drain core can be connected to the floor drain by a screw thread, or a sealing ring can be provided at the lower edge of the water inlet 11 of the floor drain core to form a sealing fit with the floor drain. In order to remove the floor drain core from time to time for cleaning and maintenance, a handle can also be provided at the water inlet 11 of the floor drain core.

[0031] With the water-sealed floor drain core of the above structure, sewage flows out from the water outlet 12 to the water storage cup 2 after being pressurized from the water inlet 11. When the water level in the water storage cup 2 reaches the height of the overflow port 21, it is discharged from the overflow port 21. When the water supply is cut off, the water flow fills the water storage cup 2, thereby achieving insect prevention and odor isolation.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the scope of the present invention are intended to fall within the scope of protection.
