DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are involved in the scope of the utility model.

[0026] As Figures 1-2 shown, the embodiment discloses a multi-pass anti-reverse-odor drainage structure, which comprises a straight-through pipe 1 provided with a water inlet 11 and a water outlet 12, a drain port 2 and a backwater port 3 are arranged on the side wall of the straight-through pipe 1, a U-shaped backwater elbow 4 is connected between the drain port 2 and the backwater port 3, the backwater elbow 4 comprises a lower drain pipe 41 connected with the drain port 2 and an upper backwater pipe 42 connected with the backwater port 3, and a water trap 43 is arranged between the lower drain pipe 41 and the upper backwater pipe 42.

[0027] The through pipe 1 is also provided with an emergency communication port 5 between the water outlet 2 and the water return port 3, which can directly communicate with the water inlet 11 and the water outlet 12. The emergency communication port 5 is provided with a pipe plug 6, which includes a cover body 61 in a conical structure matched with a sealing baffle 51. The cover body 61 is wrapped with a sealing rubber 62 matched with a sealing surface. The sealing baffle 51 is provided with a sealing surface in a conical structure at one end relative to the water inlet 11.

[0028] As shown in Figure 2 In daily use, the pipe plug 6 can be plugged into the emergency communication port 5 and matched with the sealing baffle 51 to achieve complete sealing of the emergency communication port 5 through the sealing rubber 62 arranged on the side. At this time, when the user needs to discharge sewage, the sewage will enter the through pipe 1 through the water inlet 11, flow through the water return bend pipe 4, and then be discharged into the sewer pipe through the water outlet 12. The water seal of the water return bend pipe 4 is always maintained in the trap 43 of the water return bend pipe 4, and the emergency communication port 5 of the through pipe 1 is sealed by the pipe plug 6, thereby avoiding the reverse taste of the pipe.

[0029] When the solid impurities in the sewage are deposited in the trap 43 or the trap 43 is blocked by objects, the user can hold the handle on the pipe plug 6 and pull it out of the emergency communication port 5, so that the sewage can flow directly from the emergency communication port 5 to the water outlet 12 to achieve sewage discharge. When the sewage is discharged, the pipe plug 6 can seal the emergency communication port 5 again to avoid reverse taste. Therefore, before the pipe is unblocked, the user can normally discharge sewage and prevent reverse taste, reducing the impact on the user's normal life caused by pipe blockage.

[0030] As shown in Figure 2 The bottom of the trap 43 is provided with a cleaning hole 7 communicating the inside of the trap 43 with the outside. The outer wall of the trap 43 is threadedly connected with a threaded cover 8 sealing the cleaning hole 7. When the user finds that the water return bend pipe 4 is blocked, the user can open the threaded cover 8 to take out the solid substances blocking the pipe from the cleaning hole 7, thereby achieving self-unblocking of the pipe, making the unblocking more convenient and fast.

[0031] Example Two

[0032] As shown in Figure 3As shown, on the basis of Example 1, the drain outlets 2 and the return water outlets 3 are distributed in pairs along the length direction of the straight pipe 1, and several groups of drain outlets 2 and return water outlets 3 and return water bends 4 connecting each group of drain outlets 2 and return water outlets 3 are distributed around the straight pipe 1; multiple return water bends 4 distributed around the straight pipe 1 can improve the drainage efficiency, and when one of them is blocked, the user can still discharge the sewage normally.

[0033] Example 3

[0034] like Figures 3-6 As shown, on the basis of Example 1 or Example 2, a magnetic strip 52 is provided at one end of the sealing strip 51 opposite to the water inlet 11, and a magnet 53 adsorbed by the magnetic strip 52 is provided on the edge of the cover body 61; by providing the magnetic strip 52 on the sealing strip 51 and the magnet 53 on the edge of the cover body 61, the sealing effect between the pipe plug 6 and the strip can be improved, and at the same time, it can avoid that a large water flow impacts the pipe plug 6 and causes the position of the pipe plug 6 to move and affect the sealing.

[0035] like Figures 5-6 As shown, the filter cartridge 9 is detachably connected to the side of the cover body 61 opposite to the water inlet 11, and a groove 91 is provided on the side of the cover body 61 opposite to the filter cartridge 9, and a locking block 92 is elastically provided on the edge of the groove 91; a connecting ring 93 that is snap-fitted with the locking block 92 is provided on the edge of one end of the filter cartridge 9 opposite to the cover body 61; and a notch 94 that matches the shape of the locking block 92 is provided on the connecting ring 93.

[0036] During use, the filter cartridge 9 can be fixed on the top of the pipe plug 6, thereby filtering larger objects in the sewage flowing through the drain outlet 2, preventing larger objects from entering the return bend 4 and causing blockage, and preventing important objects from falling into the sewer.

[0037] The filter cartridge 9 can be connected to the cover 61 through the locking block 92. The top of the locking block 92 is conical and has a certain degree of elasticity. When installing the filter cartridge 9, the user can directly connect the connecting ring 93 of the filter cartridge 9 to the groove 91 of the cover 61. Then the locking block 92 will be stuck above the connecting ring 93 to limit and fix the connecting ring 93. In this way, when the user needs to take valuables from the filter cartridge 9, the bottom of the filter cartridge 9 is supported by the cover 61, and the valuables can be taken up together with the cover 61. In addition, when the user needs to take the pipe plug 6 to discharge sewage, the pipe plug 6 can be pulled out through the filter cartridge 9 without having to reach into the straight-through pipe 1.

[0038] And the connecting ring 93 of the filter cartridge 9 is provided with a notch 94 matched with the locking block 92, when the user wants to separate the filter cartridge 9 from the pipe plug 6, the user can rotate the filter cartridge 9 to drive the connecting ring 93 to rotate, and make the notch 94 on the connecting ring 93 rotate to the position of the locking block 92, so that the connecting ring 93 can be directly separated from the cover 61. Such a design can make the impurities in the filter cartridge 9 be paper towels or some impurities that can pass through the backwater bend 4, and the user can simply disassemble the filter cartridge 9, so that the impurities left on the pipe plug 6 directly enter the drain 2 and are washed away, and the operation is more convenient.

[0039] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the design concept of the present application shall be included in the protection scope of the present application.
