[0015] The present application can be embodied in various forms and should not be construed as being limited to the exemplary embodiments described herein.
[0016] For ease of description, spatial relative terms such as "upper", "lower", "left", "right" and the like can be used herein to describe one element's or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or located in any other orientation) and the spatially relative terms used herein interpreted accordingly. EMBODIMENTS
[0017] As Figure 1 shown, the sealing rubber ring in the present embodiment is circular; the inner side of the sealing rubber ring is tapered at the upper and lower ends, forming a guide surface to facilitate extrusion from the upper and lower directions and to expand the sealing rubber ring. The sealing rubber ring is extruded from the inner side in the upper and lower directions at the same time, and the upper and lower ends of the sealing rubber ring are more evenly stressed, and the pressure distribution on the outer pipe is also more reasonable, which not only makes the connection firm, but also helps to prolong the service life of the sealing rubber ring.
[0018] The cross section of the sealing rubber ring can be a double-bevel trapezoid, i.e., an isosceles trapezoid, or a non-isosceles trapezoid with parallel top and bottom edges; or one or both bottom corners of the above-mentioned trapezoid can be truncated to form a similar double-bevel trapezoid; the use of a similar double-bevel trapezoid can shorten the width of the sealing rubber ring. EMBODIMENTS
[0019] As Figure 3As shown, the lower locking assembly of the deodorizing sewer includes an interface pipe, a locking nut, a sealing rubber ring and an expansion bolt; wherein the sealing rubber ring adopts the structure of the sealing rubber ring in Embodiment 1.
[0020] The expansion bolt and the interface pipe can be connected by clamping or by screwing. The sealing rubber ring is sleeved outside the interface pipe and is arranged between the locking nut and the expansion bolt. The locking nut is matched with the outer thread of the interface pipe through the inner thread, thereby forming an extrusion mechanism of the sealing rubber ring. The lower end of the locking nut is provided with a tapered guide structure, and the middle variable diameter part of the expansion bolt forms a tapered guide structure. The guide structures at the upper and lower ends extrude inward and expand the sealing rubber ring, so that the sealing rubber ring supports the outlet pipe (not shown in the figure) and forms a firm pipe connection. Embodiment
[0021] As Figures 2 to 4 shown, the deodorizing sewer in the embodiment includes a sewer body. A detachable deodorizing valve core 8 is arranged between the inlet and the outlet of the sewer body. The structure of the deodorizing valve core 8 is a prior art, which will not be described here.
[0022] The deodorizing valve core 8 is provided with a fixed outer edge for fixed installation. The fixed outer edge abuts against the boss in the pipe wall, thereby fixing the position of the deodorizing valve core 8 in the pipeline. The fixed outer edge is arranged on the outer wall of the deodorizing valve core 8 and can be arranged at the upper end, the middle or the lower end.
[0023] The boss can be arranged on the inner wall of the upper interface pipe 3 or the inner wall of the lower interface pipe 5. Preferably, a clamping structure with a thickness matching that of the fixed outer edge is formed between the lower end of the inner wall of the upper interface pipe 3 and the upper end of the lower interface pipe 5, so that the upper interface pipe 3 and the lower interface pipe 5 are clamped between the inlet and the outlet of the sewer body. In this way, a sealing gasket can be additionally arranged between the clamping structure and the fixed outer edge to prevent odor from overflowing from the clamping structure.
[0024] When the pipe diameter of the upper interface pipe 3 is greater than that of the lower interface pipe 5, the clamping structure can be composed of the flange at the lower end of the inner wall of the upper interface pipe 3 and the top end surface of the lower interface pipe 5. When the pipe diameter of the upper interface pipe 3 is smaller than that of the lower interface pipe 5, the clamping structure can be composed of the flange at the upper end of the inner wall of the lower interface pipe 5 and the bottom end surface of the upper interface pipe 3.

The upper locking assembly can also be used as a lower locking assembly at the lower end of the drain.
[0028] The inner wall of the inlet of the upper interface pipe 3 can also be provided with a conical cavity with a large upper part and a small lower part; the upper pipe sealing rubber ring 7 can also be provided with a conical ring body with a large upper end and a small lower end; the upper locking nut and the upper interface pipe form a threaded extrusion mechanism; the upper pipe sealing rubber ring in the conical cavity is extruded by locking the upper locking nut; the connection of the upper pipe sealing rubber ring in the conical cavity with the inlet pipe is more firm.
[0029] The bottom of the upper pipe sealing rubber ring can also be provided with a plurality of radial through grooves; the deformation of the lower end can be larger when it is extruded by the upper locking nut 4, and the connection with the inlet pipe is more firm.
[0030] The lower locking assembly can be composed of a lower interface pipe 5, a lower locking nut 2, a lower pipe sealing rubber ring 6 and an expansion bolt 1; the lower pipe sealing rubber ring 6 is sleeved outside the lower interface pipe 5 and is arranged between the lower locking nut 2 and the expansion bolt 1; the lower locking nut 2 is matched with the outer thread of the lower interface pipe 5 through the inner thread to form an extrusion mechanism of the lower pipe sealing rubber ring 6. The lower locking assembly can also be used as an upper locking assembly at the upper end of the drain.
[0031] The lower pipe sealing rubber ring 6 is a circular ring, and the cross section of the sealing rubber ring is a double-oblique-edge trapezoid; the inner upper and lower ends are both conical surfaces, forming guide surfaces; the upper conical surface has a large upper end diameter and a small lower end diameter; the lower conical surface has a small upper end diameter and a large lower end diameter; the lower locking nut 2 is matched with the conical surface of the lower end of the expansion bolt 1; when the lower locking nut 2 approaches the expansion bolt 1, the conical surfaces are matched to expand the lower pipe sealing rubber ring 6 and hold the inner wall of the outlet pipe, achieving firm connection.
[0032] The expansion bolt 1 is a variable-diameter pipe; the upper end has a small diameter, the lower end has a large diameter, and the middle part is a conical variable-diameter part. The outer wall of the upper end pipe can be provided with threads or a clamping structure; it is convenient for threaded connection or clamping with the lower interface pipe 5. The clamping structure can be a flange or a clamping groove, which is matched with the clamping groove or flange of the inner wall of the lower interface pipe 5.
[0033] The expansion plug 1 can be connected with the lower interface pipe 5 by clamping or by screwing.
