As an important component of the kitchen and bathroom drainage system in a residence, their performance directly affects indoor air quality, is very important for controlling odors in the kitchen and bathroom, and also has a certain impact on the modern home living environment.
[0003] Currently, there are many kitchen and bathroom drainers on the market, but they basically all connect the drain pipe directly to the drainage and sewage system pipes or install a "U" shaped sink trap in front of the drainage pipe. Wastewater from washing vegetables and washing hands in the kitchen and bathroom flows into the drainage and sewage pipes after passing through the "U" shaped sink trap.
[0004] The existing U-shaped traps in kitchen and bathroom drains are prone to accumulating dirt and are extremely difficult to clean. Moreover, they are not effective at preventing odors and insects, which can easily cause backflow of foul odors from the pipes and allow insects such as cockroaches to crawl into the kitchen along the drain pipes, making them inconvenient to use.
[0005] Therefore, there is an urgent need to provide a kitchen and bathroom odor-proof drain device to solve the above problems. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing kitchen and bathroom drains, such as the U-shaped sink trap being prone to accumulating dirt and being extremely difficult to clean, as well as the poor odor and insect prevention effects, which easily cause backflow of odor from the pipes and insects such as cockroaches to crawl into the kitchen along the drain pipes, making them inconvenient to use. This utility model provides a kitchen and bathroom odor-proof drain.
[0007] To solve the above-mentioned technical problems, the present invention provides a kitchen and bathroom odor-proof drain device, including a drain pipe, and further comprising:
[0008] A collection component is disposed inside the drain pipe;
[0009] The collection assembly includes an annular cylinder disposed on the side wall of the drain pipe, a filter disposed inside the annular cylinder, and a connecting unit disposed between the annular cylinder and the drain pipe.
[0010] A protective component is disposed on top of the collecting component;
[0011] The protective assembly includes a fixing bracket fixedly connected to the inner wall of the drain pipe, a connecting bracket disposed at the bottom of the fixing bracket, and a sealing unit disposed at the bottom of the connecting bracket.
[0012] The present invention is further configured such that: a drain pipe is provided at the top of the drain pipe, and a horizontal pipe is installed at the bottom side of the drain pipe.
[0013] The present invention is further configured such that: the side wall of the drain pipe is provided with a break, and the collection component is disposed at the break.
[0014] The present invention is further configured such that: the filter element includes a placement groove disposed on the inner wall of the annular cylinder, a filter cylinder disposed inside the placement groove, and a conical filter plate installed at the bottom center of the filter cylinder.
[0015] The present invention is further configured such that: there are two sets of connecting units, and the two sets of connecting units are respectively disposed at the upper and lower ends of the annular cylinder;
[0016] The connecting unit includes a receiving groove at the end of the annular cylinder, one end of an extruder installed on the side wall of the receiving groove, and a limiting ring installed on the other end of the extruder. The break is provided with a limiting groove that matches the size of the limiting ring.
[0017] The present invention is further configured such that: the connecting unit includes a fixing ring installed at the edge of the outer surface of the annular cylinder and a connecting ring installed at the break point, and a locking screw is provided between the connecting ring and the fixing ring.
[0018] The present invention is further configured such that: there are multiple sets of sealing units, and the multiple sets of sealing units are arranged in a ring at the bottom of the connecting frame;

[0020] The beneficial effects of this utility model are as follows:
[0021] 1. This utility model, through the setting of protective components, allows kitchen sewage to enter the drain pipe in conjunction with the drain pipe. Under the action of gravity, one end of the sealing plate rotates downward, allowing the sewage to continue to flow downward. After the sewage is discharged, the sealing plate is reset under the action of the elastic element and the telescopic rod, sealing the opening of the connecting frame, thereby preventing the backflow of odors and the intrusion of mosquitoes.
[0022] 2. This utility model, through its collection component, collects residue from wastewater as it flows downwards along the drain pipe, and uses a filter element to collect the residue. The conical filter plate prevents residue from clogging the bottom of the filter cylinder, thus preventing wastewater from flowing downwards. When a large amount of residue accumulates inside the filter cylinder and needs cleaning, first, the locking screw is rotated to separate it from the connecting ring and fixing ring. Then, the sliding push block causes the limiting ring to retract into the collection groove, separating the limiting ring from the limiting groove and releasing the limiting effect on the annular cylinder. Pulling the annular cylinder outwards allows it to be disassembled, and then pulling the filter cylinder upwards allows it to be removed, facilitating residue cleaning and making it easy to use.
