Description

Technical Field

[0001] This utility model relates to a water-sealed floor drain core, and relates to the field of floor drains. Background Technology

[0002] Floor drains are important drainage devices that connect the ground to the sewer pipes. They are mainly used to drain indoor water, such as sewage from bathrooms, balconies, and kitchens, while preventing odors, pests, and backflow of gas. In response, the market offers ordinary floor drains, water-sealed floor drains, and concealed floor drains. Water-sealed floor drains, in particular, use a water trap to create a water seal that blocks odors and provides excellent odor prevention.

[0003] However, water-sealed floor drains have the following drawbacks. Because the edge of the water seal plate of the floor drain is raised, which is a water trap structure, the drainage speed is greatly slowed down when draining. Specific usage environments: such as shower areas, where either there is no drainage or the drainage volume is very large. Ordinary water-sealed floor drains cannot achieve the effect of draining a large amount of water in a short time, which easily leads to water accumulation.

[0004] Therefore, this utility model provides a water-sealed floor drain core that has a dynamic counterweight, rapidly increases drainage volume, blocks odors, and has a good odor-proof effect. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a water-sealed floor drain core with dynamic counterweight and rapid increase in drainage volume.

[0006] This utility model is implemented as follows:

[0007] A water-sealed floor drain core includes a main body, the main body having a through hole running vertically through it, and a support being provided at the front end of the main body;

[0008] The lifting rod and the water seal plate are provided. One end of the lifting rod is fixed to the water seal plate, and the other end passes through the through hole at the bottom of the main body and is fixed to the center point of the bracket.

[0009] A water tank is located above or below the water seal plate. The water tank has several drain holes. The water inlet of the water tank is greater than the water outlet, so that the weight of the water stored in the water tank increases the descent of the water seal plate.

[0010] As a further improvement, when the water tank is located above the water seal plate, the movable rod of the lifting rod is fixed to or passes through the water seal plate, and the water tank is fixed to the movable rod of the lifting rod.

[0011] As a further improvement, when the water tank is located below the water seal plate, the movable rod of the lifting rod passes through the water seal plate, and the water tank is fixed on the movable rod of the lifting rod.

[0027] Example 1

[0028] Reference Figures 1-4 As shown, this embodiment provides a specific implementation of a water-sealed floor drain core, including a main body 10, the main body 10 having a through hole 101 extending vertically inside, and a bracket 102 at the front end of the main body 10;

[0029] The lifting rod 20 and the water seal plate 30 are provided. One end of the lifting rod 20 is fixed to the water seal plate 30, and the other end passes through the through hole 101 from the bottom of the main body 10 and is fixed to the center point of the bracket 102. This allows the lifting rod 20 to extend the water seal plate 30 and separate it from the bottom of the main body 10 to increase the drainage volume, or to shorten the lifting rod 20 and allow the water seal plate 30 to contact the bottom of the main body 10 to seal the water flow.

[0030] The water tank 40 is located below the water seal plate 30. The lifting rod 20 includes a movable rod 201 and a fixed rod 202. The fixed rod 202 is fixed to the center of the bracket 102. The movable rod 201 is slidably engaged with the fixed rod 202 through a reset component 204, and the movable rod 201 slides up and down inside the fixed rod 202 to increase the descent range of the water seal plate 30 due to the water storage weight of the water tank 40.

[0031] The principle of this embodiment is as follows: After the utility model is installed on the floor drain plate, it is installed at the connection between the ground and the sewer pipe. When the drainage volume suddenly increases, the water flows down from the top of the main body 10 to the water seal plate 30, and flows into the water tank 40 through the water inlet pipe 402. The drain hole 401 at the bottom of the water tank 40 gradually drains the water. When the water inlet volume of the water tank 40 is greater than the water outlet volume, it will start to continuously store water, and the weight of the water tank 40 will gradually increase. Under the action of the water tank 40, the lifting rod 20 and the movable rod 201 gradually extend. The water seal plate 30 separates from the bottom of the main body 10 to increase the drainage volume and drain water quickly, so as to achieve the purpose of rapidly increasing the drainage volume and quickly draining water in a short period of time.

[0032] Conversely, as the amount of water entering decreases, the weight of the water tank 40 also decreases until the weight of the water tank is less than the resetting force of the resetting component 204. This causes the movable rod 201 to reset, and at the same time, the water tank 40 returns to its original position, and the water seal plate 30 contacts the bottom of the main body 10 to seal the water flow.

[0033] In this embodiment, the water tank 40 is provided with an inlet pipe 402. One end of the inlet pipe 402 extends through the surface of the water seal plate 30 and is higher than the water sealing surface of the water seal plate 30. The other end of the inlet pipe 402 is located at the bottom of the inside of the water tank 40 and is lower than the drain hole 401 of the water tank 40.

[0034] In this embodiment, the water tank 40 has one or more drain holes 401 on its side. The drain holes 401 of the water tank 40 are positioned higher than the bottom surface of the water tank 40, so that when not in use, some water will remain at the bottom of the water tank 40 and water will also remain on the water seal plate 30, achieving the purpose of double water seal. The water seal blocks odors and has a good deodorizing effect.

[0035] In one specific embodiment, the reset component 204 is a spring or tension spring, that is, when the lifting rod 20 is reset, the weight of the water tank 40 is less than the elastic force of the reset component 204, and the elastic force of the reset component 204 causes the movable rod 201 to return to its original position.

[0036] In one specific embodiment, the reset component 204 is a magnet, that is, when the lifting rod 20 is reset, the weight of the water tank 40 is less than the magnetic force of the reset component 204, and the magnetic force of the reset component 204 carries the movable rod 201 back to its original position.

[0037] In this embodiment, the end of the fixed rod 202 that does not contact the movable rod 201 is the open end after passing through the bracket 102, and a plug 203 is provided at this end to facilitate the assembly of the entire lifting rod 20.

[0038] In this embodiment, the bracket 102 is a triangular bracket with three support rods welded together at one end. The bracket 102 has the functions of water passage and fixing the lifting rod. The bracket 102 in this embodiment adopts this structural design, which is the simplest and most robust.

[0039] In other embodiments, the bracket 102 may also be hollow, so that the bracket 102 can provide stable support.

[0040] Example 2

[0041] refer to Figures 5-8 As shown, this embodiment differs from Embodiment 1 in that the installation position of the water tank 40 is different. The water tank 40 is located above the water seal plate 30. The water tank 40 is installed on the movable rod 201 of the lifting rod 20. The movable rod 201 of the lifting rod 20 is fitted onto the outside of the fixed rod 202 and slides up and down. The reset component 204 is located at the inner top of the movable rod 201. The water tank 40 has one or more drain holes 401 for draining the water in the water tank 40.

[0042] One or more drain holes 401 are opened on the side or bottom surface of the water tank 40 so that when not in use, some water will remain at the bottom of the water tank 40 or no water will remain, and water will remain on the water seal plate 30 to achieve the purpose of water seal. The water seal blocks odors and has a good odor prevention effect.

[0043] In this embodiment, apart from the different installation positions of the movable rod 201, the fixed rod 202, and the reset component 204, the underlying principles are the same. For structures, connections, and effects not mentioned in this embodiment, please refer to Embodiment 1.

[0044] In summary, the beneficial effects of this utility model are that by dynamically changing the lifting rod and the counterweight of the water tank, the drainage volume can be rapidly increased in a short time, and the water can be discharged quickly. When not in use, the water seal plate 30 contacts the bottom of the main body 10 to seal the water flow. The water seal plate 30 or the water tank 40 has residual water at the bottom to form a water seal, which blocks odors and has a good deodorizing effect.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
