Description

Technical Field

[0001] This application relates to the field of drainer technology, specifically an odor-proof washbasin drainer. Background Technology

[0002] A drain is a drainage device installed in the drain of a bathtub, sink, etc. It can be divided into pop-up drains, flip-top drains, and pull-out drains, etc. According to material, it can be divided into all-copper drains, stainless steel drains, and plastic drains, etc. According to purpose, it can be divided into bathtub drains, sink drains, etc.

[0003] An existing patent (publication number: CN210507655U) discloses a one-piece anti-odor washbasin drain, including a drain head, a drain pipe, a transition connecting pipe, and a return pipe. One end of the return pipe is the water inlet, which connects to the drain head, and the other end is the water outlet, which connects to the drain pipe. A bend is formed between the water inlet and outlet of the return pipe to create a water storage area. The distance between the highest point of the water inlet and the lowest point of the return pipe is less than 8 cm. This utility model uses a water-sealed anti-odor technology with a return bend, effectively preventing odors from returning. The drainage direction is straight, ensuring smooth drainage. The transition connecting pipe and the return pipe are two detachable parts, allowing for easy disassembly and cleaning if clogged by hair or other debris. Installation is not restricted by environment (especially in modern homes with integrated bathroom cabinets), greatly increasing the device's practicality.

[0004] The aforementioned document describes a method to prevent backflow of odors by using a water trap to seal the pipe during use. However, if the pipe is not used for a long time, the water in the trap will dry up, and the odor will rise along the pipe. Overall, its practicality needs to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an odor-proof sink drain with advantages such as tttt, which solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: an odor-proof washbasin drainer, comprising a first component, a second component threadedly connected to the upper surface of the first component, a water-blocking cover slidably connected to the upper surface of the second component, a plurality of circumferentially distributed filter screens installed on the inner wall of the water-blocking cover, a conical drainage component provided inside the first component, a sealing cap hinged to the bottom end of the conical drainage component, a bent pipe threadedly connected to the bottom end of the first component, a liquid level sensor installed on the outer surface of the bent pipe, and an inlet pipe fixedly connected to the outer surface of the bent pipe.

[0007] The above solution involves installing a bent pipe to block the entire pipeline by allowing water to accumulate, and in conjunction with a water-blocking cap, it can prevent odors from backing up.

[0008] A storage frame is installed on the outer surface of the bent pipe. The liquid inlet pipe is fixedly connected to the bottom end of the storage frame. A solenoid valve is installed on the outer surface of the storage frame. Both the liquid level sensor and the solenoid valve are electrically connected to external control equipment. The solenoid valve can seal the liquid inlet pipe. With the cooperation of the liquid level sensor, when there is water accumulation in the bent pipe, a descaling agent with fragrance can be discharged into the water. This not only removes the odor of the water but also cleans the dirt in the water accumulation area.

[0009] The upper surface of the storage frame is threaded with a protective cover. The upper surface of the protective cover has a slot. Installing the protective cover can seal the storage frame, and the slot allows the inside of the storage frame to communicate with the atmosphere, facilitating the flow of the descaling agent in the liquid inlet pipe.

[0010] The right end of the bent pipe is threaded with a corrugated pipe. Installing the corrugated pipe can facilitate extending the drainage length and allowing sewage to be discharged according to the user's needs.

[0011] The outer surface of the second component has two threaded fasteners. Installing the two fasteners makes it easy to install the second component onto the washbasin, thereby fixing the second component in place and allowing wastewater in the washbasin to be discharged through the second component.

[0012] The inner wall of the second component is equipped with a spring mechanism. The upper surface of the spring mechanism is fixedly connected to the water-blocking cover. The spring mechanism allows the water-blocking cover to pop out when the user presses it, so that the sewage can be filtered through the filter screen and discharged.

[0013] A sealing ring is provided between the conical drainage component and the first component. The sealing ring, when installed in conjunction with the sealing cover, can block odors and prevent odors from being discharged through the first component.

[0014] The curved section at the tail of the bent pipe is higher than the middle section, which facilitates water retention inside the bent pipe and allows the water inside the bent pipe to block odors.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This odor-proof washbasin drain features a bend pipe that seals the entire pipe system with accumulated water, preventing backflow of odors. A liquid level sensor, working in conjunction with the inlet pipe, releases a scented descaling agent into the bend pipe when water accumulates, removing odors and cleaning the area. A conical drain fitting, combined with a sealing cap, further seals the entire pipe system, preventing odors from passing through even after the water in the bend pipe dries, thus enhancing overall usability.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The odor-proof sink drain in this embodiment includes a first component 1, a second component 2 threadedly connected to the upper surface of the first component 1, a water-blocking cover 3 slidably connected to the upper surface of the second component 2, a plurality of circumferentially distributed filter screens 4 installed on the inner wall of the water-blocking cover 3, a conical drain component 5 provided inside the first component 1, a sealing cover 6 hinged to the bottom end of the conical drain component 5, a torsion spring installed between the sealing cover 6 and the conical drain component 5, a bent pipe 7 threadedly connected to the bottom end of the first component 1, a liquid level sensor 8 installed on the outer surface of the bent pipe 7, and the outer surface of the bent pipe 7 being fixedly connected to... The system has an inlet pipe 9. By installing a bend pipe 7, the system can seal the entire pipeline with accumulated water to prevent odor backflow. In conjunction with the liquid level sensor 8, the system can release a fragrant descaling agent into the bend pipe 7 when there is water accumulation. This not only removes odors but also cleans the water accumulation area in the bend pipe 7. By installing a conical drain piece 5 and a sealing cap 6, the system can further seal the entire pipeline. Even after the water in the bend pipe 7 dries up, odors still cannot pass through the first component 1, thereby improving the overall practicality.

[0025] Please see Figure 1 , Figure 2 and Figure 4 A storage frame 10 is installed on the outer surface of the bent pipe 7. The inlet pipe 9 is fixedly connected to the bottom end of the storage frame 10. A solenoid valve 11 is installed on the outer surface of the storage frame 10. The liquid level sensor 8 and the solenoid valve 11 are electrically connected to external control equipment. The solenoid valve 11 can seal the inlet pipe 9. With the cooperation of the liquid level sensor 8, when there is water in the bent pipe 7, a descaling agent with fragrance can be discharged into the water. This can not only remove the odor of the water, but also clean the dirt in the water. A cover 12 is threadedly connected to the upper surface of the storage frame 10. The upper surface of the cover 12 has a slot 13. The cover 12 can seal the storage frame 10. The slot 13 allows the storage frame 10 to communicate with the atmosphere, which facilitates the flow of the descaling agent in the inlet pipe 9. A corrugated pipe 14 is threadedly connected to the right end of the bent pipe 7. The corrugated pipe 14 can extend the drainage length and facilitate the discharge of sewage according to the user's needs.

[0026] Please see Figure 1 , Figure 2 and Figure 3 The outer surface of the second component 2 is threaded with two clips 15. Installing the two clips 15 makes it easy to install the second component 2 onto the washbasin, thereby fixing the second component 2 and allowing the sewage in the washbasin to be discharged through the second component 2. The inner wall of the second component 2 is equipped with a spring mechanism 16. The upper surface of the spring mechanism 16 is fixedly connected to the water-blocking cover 3. When the user presses the water-blocking cover 3, the water-blocking cover 3 will pop out, allowing the sewage to be filtered through the filter screen 4 and discharged. A sealing ring 17 is provided between the conical drain piece 5 and the first component 1. The sealing ring 17 can be installed in conjunction with the sealing cover 6 to block odors and prevent odors from being discharged through the first component 1. The tail of the bent pipe 7 is higher than the middle arc. The tail of the bent pipe 7 is higher than the middle arc, which allows water to accumulate in the bent pipe 7, so that the water in the bent pipe 7 can block odors.

[0027] The odor-proof sink drain in this embodiment, by installing a bend pipe 7, can seal the entire pipe with accumulated water to prevent odor backflow. In conjunction with the liquid level sensor 8 and the inlet pipe 9, when there is water in the bend pipe 7, a fragrant descaling agent is discharged into the bend pipe 7, which not only removes odors but also cleans the water accumulation area in the bend pipe 7. By installing a conical drain piece 5 and a sealing cap 6, the entire pipe can be further sealed. Even after the water in the bend pipe 7 dries up, odors still cannot pass through the first component 1, thereby improving the overall practicality.

[0028] The working principle of the above embodiment is as follows: During installation, two clips 15 are used to install the second component 2 onto the external washbasin. Then, the first component 1 is connected to the second component 2, and the second component 2 is connected to the bent pipe 7. When sewage needs to be discharged, the water-blocking cover 3 is pressed, causing the spring-loaded structure to pop out the water-blocking cover 3, allowing multiple filter screens 4 to be carried out, so that impurities in the sewage can be intercepted by the filter screens 4, allowing the sewage to be discharged through the second component 2 and the first component 1. When the sewage passes through the sealing cover, the sealing cover will swing due to gravity, allowing the sewage to enter the bent pipe 7. Through the design of the bent pipe 7, some of the water will be retained in the bent pipe 7, which can block odors. At this time, the liquid level sensor 8 can... The presence of water in the bend pipe 7 is detected, and a signal is transmitted to an external control device. The external control device can send a signal a few minutes later to open the solenoid valve 11, allowing the descaling agent in the storage box 10 to enter the bend pipe 7 through the inlet pipe 9. With the cooperation of the liquid level sensor 8 and the inlet pipe 9, when there is water in the bend pipe 7, a fragrant descaling agent is discharged into the bend pipe 7, which not only removes odors but also cleans the water accumulation area in the bend pipe 7. By installing the conical drain piece 5 and the sealing cap 6, the entire pipeline can be further sealed, ensuring that even after the water in the bend pipe 7 dries up, odors still cannot pass through the first component 1, thereby improving the overall practicality.
