The setting mode of the threaded pipe 21 can be set as an external thread or an internal thread.

[0034] As Figure 3 , 4 , 5, an inspection rod 31 is connected to the inspection cover 3. When the inspection cover 3 is connected to the connecting pipe 2, the inspection rod 31 is arranged inside the connecting pipe 2. A sealing ring 32 is connected to the side of the inspection rod 31 away from the inspection cover 3, and the sealing ring 32 abuts against the inner wall of the connecting pipe 2. A plugging plate 33 is arranged on the side of the inspection rod 31 away from the inspection cover 3, and an annular clamping groove 34 is arranged on the plugging plate 33, and the annular clamping groove 34 clamps and connects the sealing ring 32.

[0035] The inspection rod 31 is connected to the inspection cover 3, and the side of the inspection rod 31 close to the water storage bend area 11 extends. The inspection rod 31 is arranged inside the connecting pipe 2. Through the inspection rod 31, the water flow in the water storage bend area 11 can be prevented from directly flowing into the connecting pipe 2, thereby ensuring the smoothness of drainage, avoiding the generation of turbulent flow here, and reducing the risk of foreign objects blocking here. A sealing ring 32 is connected to the side of the inspection rod 31 away from the inspection cover 3, and the sealing ring 32 abuts against the inner wall of the connecting pipe 2, thereby ensuring the sealing effect. A plugging plate 33 is arranged on the inspection rod 31, and an annular clamping groove 34 is arranged on the plugging plate 33.

[0036] As Figure 2 shown, the drainage channel 4 includes a first channel 41, the first channel 41 is connected to a second channel 42, a water storage bend area 11 is formed at the connection between the first channel 41 and the second channel 42, and the drainage channel 4 is in a horizontally placed "S" - shaped structure. The first channel 41 is connected to a water inlet interface 14, the second channel 42 is connected to a third channel 43, a return bend 15 is formed between the second channel 42 and the third channel 43, and the third channel 43 is connected to a drain pipe 16. The horizontally placed "S" - shaped structure can ensure the smoothness of drainage. The drainage channel 4 in this application is designed with a first channel 41, a second channel 42 and a third channel 43. Further, the water storage bend area 11 is formed between the first channel 41 and the second channel 42, and the return bend 15 is formed between the second channel 42 and the third channel 43. The return bend 15 structure enables the drainage channel 4 to extend downward again for drainage connection.

[0037] In this embodiment, the assembly and working process of a concealed wall-mounted trap device are as follows: In this embodiment, the drainage channel 4 is divided into a first channel 41, a second channel 42, and a third channel 43. A trap area 11 is formed between the first channel 41 and the second channel 42. A return bend 15 is formed between the second channel 42 and the third channel 43. Therefore, in this embodiment, water flows into the first channel 41 through the water inlet interface 14, then the water flows through the first channel 41 to the trap area 11, flows through the bend in the trap area 11 into the second channel 42, and flows through the return bend 15 in the second channel 42 to the third channel 43. In this embodiment, the third channel 43 is connected to the drain pipe 16, and the water flows into the drain pipe 16 in the third channel 43. Among them, the water flow in this embodiment can form a water seal at the trap area 11, thereby avoiding the occurrence of sewer odor backflow, flying insects, virus transmission, etc. Further, in this embodiment, a connecting pipe 2 is connected to the trap area 11. The connecting pipe 2 is a hollow structure, and an inspection cover 3 is connected to the connecting pipe 2. In this embodiment, the setting direction of the connecting pipe 2 extends toward the wall surface side. During installation, the connecting pipe 2 can be exposed on the wall surface. The connecting pipe 2 is a threaded pipe 21, including an internal thread and an external thread setting method. During installation, the excessive part of the connecting pipe 2 needs to be cut off to reduce the protruding part of the connecting pipe 2.

[0038] During use, when water enters through the water inlet interface 14 and the water flow moves in the drainage channel 4, impurity accumulation will occur at the trap area 11, and there is a risk of blockage during use. In this embodiment, since the connecting pipe 2 communicates with the trap area 11, after removing the inspection cover 3, impurities on the trap area 11 can be cleaned by inserting a tool through the connecting pipe 2. Since the connecting pipe 2 is arranged toward the wall surface side, maintenance personnel can directly visually observe the blockage state inside the trap area 11 through the connecting pipe 2 and can better control the tool for maintenance work.

[0039] Further, in this embodiment, a maintenance rod 31 is connected to the maintenance cover 3. The maintenance rod 31 is arranged towards the side of the water trap area 11. One end of the maintenance rod 31 close to the water trap area 11 blocks and seals the connection channel between the water trap area 11 and the connecting pipe 2, so that the water flow in the first channel 41 can only flow through the water trap area 11 to the second channel 42, avoiding the water flow in the water trap from flowing into the connecting pipe 2, thus ensuring the smoothness of the water flow and reducing the risk of blockage. The water trap maintenance rod 31 is of a cylindrical structure. A sealing plate 33 is arranged on the side of the maintenance rod 31 close to the water trap area 11. An annular clamping groove 34 is arranged on the sealing plate 33. The annular clamping groove 34 is clamped and connected with a sealing ring 32. The sealing ring 32 abuts against the inner wall of the connecting pipe 2, so as to achieve the sealing effect on the connecting pipe 2 and prevent the water flow from entering the inside of the connecting pipe 2. The maintenance rod 31 is connected to the maintenance cover 3. When the maintenance cover 3 is detached from the connecting pipe 2, the maintenance cover 3 can drive the maintenance rod 31 to synchronously detach from the inside of the connecting pipe 2. The middle of the maintenance rod 31 is of a hollow structure, which can reduce the weight and at the same time reduce the production cost.

[0040] Embodiment 2:

[0041] As Figure 3 shown, different from Embodiment 1, in this embodiment, as Figure 1 shown, the water trap body 1 includes a box body 12, and a cover body 13 is detachably connected to the box body 12. The connecting pipe 2 is arranged on the cover body 13. The water trap body 1 includes a box body 12 and a cover body 13. By setting the separable structure of the box body 12 and the cover body 13, it is convenient for processing and production, thus improving the production efficiency and reducing the production cost. Further, it is convenient to process the internal drainage channel 4 and is convenient for installation. Arranging the connecting pipe 2 on the cover body 13 can be adapted according to the actual construction requirements, improving the installation flexibility.

[0042] As Figure 3 shown, the water trap body 1 is of a flat box-shaped structure. A plurality of partition plates 17 are arranged inside the water trap body 1, and drainage channels 4 are formed between the partition plates 17. Setting the water trap body into a flat box-shaped structure can improve the space utilization rate, ensure the placement stability, ensure the transportation stability, and at the same time facilitate grooving installation on the wall. At the same time, since the partition plates arranged inside the water trap body divide the cavity structure of the water trap body to form drainage channels, the drainage channels are more integrally arranged, reducing the volume, facilitating production and processing, and being convenient for transportation when combined with the flat box-shaped structure.

[0043] In this embodiment, the assembly and working process of a concealed wall-mounted trap device are as follows: In this embodiment, the trap body 1 is divided into two parts, namely the box body 12 and the cover body 13. The box body 12 and the cover body 13 are respectively processed and formed, so as to improve the forming quality, reduce the forming difficulty, and at the same time facilitate the processing and correction of the drainage channel 4. In this embodiment, the trap body 1 is a box-shaped flat structure, which can effectively utilize space, is convenient for production, and is convenient for processing the wall groove where the device is installed. At the same time, the box-shaped flat structure is beneficial to improving the stability of the device, so it is convenient for transportation and storage. Among them, in this embodiment, the water inlet interface 14, the trap area 11, and the drain pipe 16 are on the same vertical line, so as to ensure the smoothness of drainage and facilitate connection with other pipes.

[0044] The drainage channel 4 in the trap body 1 is arranged in the box body 12. In this embodiment, the drainage channel 4 is divided into a first channel 41, a second channel 42, and a third channel 43. A trap area 11 is formed between the first channel 41 and the second channel 42. A return bend 15 is formed between the second channel 42 and the third channel 43. Therefore, in this embodiment, water flows into the first channel 41 through the water inlet interface 14, then the water flows through the first channel 41 to the trap area 11, flows through the bend in the trap area 11 to the second channel 42, and then flows through the return bend 15 in the second channel 42 to the third channel 43. In this embodiment, the third channel 43 is connected to the drain pipe 16, and the water flows in the third channel 43 to the drain pipe 16. Among them, the water flow in this embodiment can form a water seal at the trap area 11, so as to avoid the occurrence of sewer odor return, flying insects, virus transmission and other situations. Further, in this embodiment, a connecting pipe 2 is connected to the trap area 11. The connecting pipe 2 is a hollow structure, and a maintenance cover 3 is connected to the connecting pipe 2. In this embodiment, the setting direction of the connecting pipe 2 extends toward the wall surface side. During installation, the connecting pipe 2 can be exposed on the wall surface. The connecting pipe 2 is a threaded pipe 21, including an internal thread and an external thread setting method. During installation, the excessive part of the connecting pipe 2 needs to be cut off to reduce the protruding part of the connecting pipe 2.

[0045] During use, when water enters through the water inlet interface 14 and the water flow moves in the drainage channel 4, impurities will accumulate at the trap area 11, and there will be a risk of blockage during use. In this embodiment, since the connecting pipe 2 communicates with the trap area 11, after removing the maintenance cover 3, tools can be inserted through the connecting pipe 2 to clean the impurities on the trap area 11. Since the connecting pipe 2 is arranged toward the wall surface side, maintenance personnel can directly visually observe the blockage state inside the trap area 11 through the connecting pipe 2, and at the same time can better control the tools for maintenance work.

[0046] Furthermore, in this embodiment, a maintenance rod 31 is connected to the maintenance cover 3. The maintenance rod 31 is arranged towards the side of the water seal bend area 11. One end of the maintenance rod 31 close to the water seal bend area 11 blocks and seals the connection channel between the water seal bend area 11 and the connecting pipe 2, so that the water flow in the first channel 41 can only flow through the water seal bend area 11 to the second channel 42, avoiding the water flow in the water seal bend from flowing into the connecting pipe 2, thereby ensuring the smoothness of the water flow and reducing the risk of blockage. The water seal maintenance rod 31 is of a cylindrical structure. A sealing plate 33 is arranged on the side of the maintenance rod 31 close to the water seal bend area 11. An annular clamping groove 34 is arranged on the sealing plate 33. The annular clamping groove 34 is clamped and connected with a sealing ring 32. The sealing ring 32 abuts against the inner wall of the connecting pipe 2, thereby realizing the sealing effect on the connecting pipe 2 and preventing the water flow from entering the inside of the connecting pipe 2. The maintenance rod 31 is connected to the maintenance cover 3. When the maintenance cover 3 is disengaged from the connecting pipe 2, the maintenance cover 3 can drive the maintenance rod 31 to synchronously disengage from the inside of the connecting pipe 2. The middle of the maintenance rod 31 is of a hollow structure, which can reduce the weight and at the same time reduce the production cost.
