Technical Field

[0001] The utility model relates to the technical field of floor drains, in particular to an odor-proof and antibacterial floor drain. Background Art

[0002] There are roughly two types of odor-proof structures of existing floor drain cores. One is that a self-closing valve is set at the water outlet at the bottom of the floor drain core. The valve opens under the impact of water flow when draining water, and automatically closes under the action of magnetism or elastic force when not draining water. The other is that the floor drain core is provided with a water seal structure to prevent the odor from the sewer from rising.

[0003] Invention patent CN201010190372.7 discloses a water-sealed floor drain core, which achieves the purpose of odor prevention by forming a water seal between the water outlet of the inner tube and the water outlet of the floor drain core shell. However, the bottom of the water seal is a concave structure with a low middle and high periphery. The debris entering the water storage pipe (including but not limited to hair or fibers and other slender debris and other debris entering the floor drain) will be deposited at the bottom of the water seal, which will affect the drainage and odor prevention of the floor drain after long-term use.

[0004] In addition, there is a certain amount of sewage in the water seal for a long time. When the floor drain is not drained for a long time, a large number of bacteria will easily breed in the water seal, causing the floor drain to become a source of pathogen transmission. Summary of the invention

[0005] The utility model aims to provide an odor-proof and antibacterial floor drain to solve the problem that debris is easily accumulated at the water seal of the existing floor drain.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: an odor-proof and antibacterial floor drain, which can be used for floor drainage or water pipe drainage, and comprises a first cylinder and a second cylinder, the first cylinder is provided with a water storage part, the second cylinder is provided with a water discharge part, the water discharge part is sleeved in the water storage part, and there is a certain distance between the outer wall of the water discharge part and the inner wall of the water storage part, the top of the water storage part is provided with an overflow port, so that the water storage part forms a water seal structure; the inner bottom surface of the water storage part is provided with a protrusion, and in the radial direction of the water discharge part, the protrusion is located on the inner side of the water discharge part.

[0007] In one embodiment, in the radial direction of the water launching portion, the protrusion is located at the center of the water launching portion.

DETAILED DESCRIPTION

[0035] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0036] Example 1

[0037] See also Figures 1 to 7 As shown, the utility model discloses an odor-proof and antibacterial floor drain, which includes a first cylinder 1 and a second cylinder 2. The first cylinder 1 is provided with a water storage part 11, and the second cylinder 2 is provided with a water discharge part 21. The water discharge part 21 is sleeved in the water storage part 11, and there is a certain distance between the outer wall of the water discharge part 21 and the inner wall of the water storage part 11. The top of the water storage part 11 is provided with an overflow port 110, so that the water storage part 11 forms a water seal structure. The water seal structure can prevent the odor of the sewer from flowing back into the room through the floor drain, so that the floor drain can achieve a reliable odor-proof effect.

[0038] The inner bottom surface of the water storage part 11 is provided with a protrusion 12, and in the radial direction of the water discharge part 21, the protrusion 12 is located inside the water discharge part 21. The protrusion 12 located inside the water discharge part 21 can ensure that the water from the water discharge part 21 can directly impact the protrusion 12 only under the action of gravity, and turn under the action of the protrusion 12, thereby increasing the water flow speed, so that the debris mixed in the water flow can be discharged into the sewer along with the water flow, and the debris is prevented from accumulating on the inner bottom surface of the water storage part 11. Secondly, the protrusion 12 can reduce the area of ​​the inner bottom surface of the water storage part 11, so that the speed of the water flow from the water discharge part 21 to the water storage part 11 on the inner bottom surface of the water storage part 11 is further accelerated, which is conducive to the water flow to carry away the debris mixed therein and reduce the deposition at the bottom of the water seal. Finally, the reduced area of ​​the bottom surface of the water storage part 11 can reduce the space for accumulating debris, which is beneficial for keeping the inside of the water storage part clean and reducing the double protection of odor and reptiles from invading the room.

[0039] In this example, in order to allow the water flow from the water discharge portion 21 to effectively impact the protruding portion 12, the protruding portion 12 is located at the center of the water discharge portion 21 in the radial direction of the water discharge portion 21. In other embodiments, it is also feasible that the protruding portion 12 deviates from the center position of the water discharge portion 21, as long as the water flow can impact the protruding portion 12.

[0040] The top of the protrusion 12 is lower than the lower edge of the water discharge portion 21, so that a water flow channel can be formed between the protrusion 12 and the water discharge portion 21, and the protrusion 12 can be prevented from occupying the radial space of the water discharge portion 21 and reducing the cross-sectional area of ​​the water flow channel.

[0041] The water storage part 11 is provided with an antibacterial component 3. The antibacterial component 3 in this example is arranged on the protrusion 12. The antibacterial component 3 is installed by utilizing the height of the protrusion 12. The material of the antibacterial component 3 can be selected from copper or silver. In this example, copper is preferred, more specifically, a copper nail. The protrusion 12 is provided with a groove for installing the copper nail. The copper nail is arranged in the groove of the protrusion 12, so that the protrusion 12 and the copper nail cooperate on the inner bottom surface of the water storage part 11 to form a structure with a middle protrusion and a gradual inclination from the middle to the surroundings. When the water flows through the bottom end of the water storage part 11, it is smoother and the water flow speed is greater. In other embodiments, the antibacterial component 3 can also be an antibacterial coating coated on the inner surface of the water storage part 11.

[0042] See also Figure 5 As shown, in this example, an annular check cover 4 is provided above the water storage part 11, which is similar to a piston and can move up and down under the action of hydraulic force. The annular check cover 4 is slidably connected with the second cylinder 2. The annular check cover 4 is provided with a matching portion 41 extending in a direction away from the water storage part 11. The matching portion 41 is sleeved on the outside of the water discharge part 21. The outer wall of the water discharge part 21 forms a sliding guide structure of the annular check cover 4, so that the annular check cover 4 selectively rises away from the overflow port 110 to open the overflow port 110 or covers the overflow port 110 to close the overflow port 110. Fig. 9 As shown, in another embodiment, the second cylinder 2 is further provided with a guide portion 22 surrounding the outside of the water discharge portion 21 and extending in the direction of the water storage portion 11, and the matching portion 41 is sleeved between the water discharge portion 21 and the guide portion 22. The guide portion 22 guides the matching portion 41 on the outside of the matching portion 41, so that the gap between the water discharge portion 21 and the guide portion 22 forms a sliding guide structure of the annular check cover 4. The check cover 4 slides up and down relative to the water discharge portion 21 and the water storage portion 11, and reciprocates under the thrust of the water flow and the gravity, forming a piston-type structure. The annular check cover 4 is also provided with an annular check portion 42 connected to the matching portion 41. The annular check portion 42 is an annular structure sleeved outside the water discharge portion 21. The overflow port 110 is also an annular structure, which is formed between the inner side of the water storage portion 11 and the outer side of the water discharge portion 21, so that the annular check portion 42 can effectively cover the overflow port 110. When water enters the water inlet 211 at the top of the lower water section 21, the water flows upward through the water storage section 11 to the overflow port 110, and the water pushes the annular check cover 4 to move upward and open the overflow port 110, and the water flows into the sewer from the overflow port 110. When water does not enter the water inlet 211 at the top of the lower water section 21, the water in the water storage section 11 reaches a balance to form a water seal, and the annular check cover 4 moves downward under the action of gravity to close the overflow port 110, preventing the odor of the sewer and living organisms (such as reptiles) from entering the room from the floor drain. The annular check cover 4 and the water storage section 11 are combined to form a double check.

[0043] See also Figures 2 to 5 as well as Figure 7As shown, a sawtooth-shaped intercepting portion 24 is provided at the top of the second cylinder 2 to intercept the elongated debris mixed in the water flow about to enter the water inlet 211, the elongated debris including but not limited to hair, fibers, etc. The intercepting portion 24 in this example is an annular structure, and has two intercepting portions 24, which are arranged at intervals. In other embodiments, the intercepting portion 24 can be other structures, such as a long strip structure arranged on the top surface of the second cylinder 2, and a plurality of long strip intercepting portions 24 are arranged at intervals to increase its interception range.

[0044] See also Figures 1 to 7 As shown, the first cylinder 1 is provided with a first mounting portion 13, and the first mounting portion 13 is connected to the water storage portion 11 through a plurality of connecting portions 14, and the plurality of connecting portions 14 are arranged at intervals along the circumference of the water storage portion 11 on the outside of the water storage portion 11. The plurality of connecting portions 14 are arranged at intervals so that the water flow of the overflow port 110 can be discharged from the gaps between the connecting portions 14, and the water storage portion 11 is installed and fixed by the connecting portions 14. The connecting portion 14 of this example is arranged at the top of the water storage portion 11 and is integrally formed with the water storage portion 11, which simplifies the structure of the first cylinder 1 and reduces the difficulty of manufacturing the first cylinder 1.

[0045] The first mounting portion 13 is connected to the second cylinder 2 to form the installation and fixation of the first cylinder 1. The second cylinder 2 is provided with a second mounting portion 23. The second mounting portion 23 is connected to the floor drain body 5 to realize the installation and fixation of the second cylinder 2. The first mounting portion 13 and the second cylinder 2 are connected by threaded connection, which can not only realize the fixation of the first cylinder 1, but also enhance the sealing between the first mounting portion 13 of the first cylinder 1 and the second cylinder 2, and prevent the odor of the sewer from leaking into the room through the gap between the first mounting portion 13 and the second cylinder 2.

[0046] The floor drain can be used for ground drainage as well as water pipe drainage. The drain pipe can be inserted into the drain part to drain water pipes and achieve drainage of sinks, washing machines and other washing equipment.

[0047] Example 2

[0048] See also Figures 8 to 9 As shown, the floor drain can be used for ground drainage or water pipe drainage. The drainage pipe can be inserted into the drain part to drain water pipes, so as to achieve drainage of washing equipment such as sinks and washing machines. The difference between this example and Example 1 is that the connection part 14 of this example extends downward from the first mounting part 13 to the middle of the water storage part 11 and is connected to the outside of the water storage part 11, so that the overall structure of the water storage part 11 is more stable, the distance between the connection part 14 and the overflow port 110 is increased, and the influence of the connection part 14 on the water flow at the overflow port 110 is reduced.

[0049] Example 3

[0050] See also Fig.10As shown, the floor drain can be used for ground drainage or water pipe drainage. The drain pipe can be inserted into the lower part to drain the water pipe, so as to achieve drainage of sinks, washing machines and other washing equipment. The difference between this example and Example 1 is that the first cylinder 1 and the floor drain body 5 are integrally formed, and the floor drain body 5 forms a first mounting portion 13, and the second cylinder 5 is provided with a second mounting portion 23, and the second mounting portion 23 is connected to the first mounting portion 13 to achieve the installation and fixation of the second cylinder 2. More specifically, the second mounting portion 23 is provided with a groove for installing a sealing ring, and the second mounting portion 23 is connected to the floor drain body 5 through the sealing ring. The integral molding of the first cylinder 1 and the floor drain body 5 can reduce the number of parts and the connection structure between the parts, thereby reducing the chance of odor or germs entering the room from the connection between the parts.

[0051] Example 4

[0052] See also Figure 11 to Figure 12 As shown, the difference between this example and Example 1 is that the floor drain can be used for water pipe drainage. The floor drain is protruding from the ground so that the drainage pipe can be directly plugged into it for drainage. More specifically, the drainage pipe is plugged into the lower water part 21 of the second cylinder 2 from top to bottom to achieve drainage of washing equipment such as sinks and washing machines. The lower end of the floor drain body 5 is plugged into the drainage pipe on the ground, and the floor drain body 5 is a circular structure.
