Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A deodorizer for sewer pipes, please refer to fig. 1 to 8.

As shown in fig. 1, the sewer pipe deodorizer comprises a shell 1 and a sealing cover 2, as shown in fig. 2, the shell 1 is similar to a horseshoe-shaped hollow structure, as shown in fig. 3, the shell 1 is provided with an upper port 11 and a lower port 12 which are vertically communicated, a sealing ring 3 is sleeved on the upper port 11, as shown in fig. 4, an annular groove 31 is arranged in the sealing ring 3, the annular groove 31 is sleeved on the upper port 11, and the sealing ring 3 is an elastic sealing ring made of rubber or silica gel.

The closing cap 2 is used for covering the lower port 11 of the casing 1, one side of the closing cap 2 is hinged on the casing 1, as shown in fig. 5, two sides of the bottom of the casing 1 are respectively provided with a hinge shaft 13, two sides of the closing cap 2 are correspondingly provided with ear seats 21, the ear seats 21 are provided with hinge holes hinged on the hinge shaft 13, and the closing cap 2 can rotate along the hinge shaft 13.

An elastic part is arranged between the cover 2 and the casing 1, as shown in fig. 7, the elastic part is a spring 4, a hollow upright post 14 is arranged on one side of the casing 1, an inclined step part 15 is arranged on the rear side surface of the lower part of the casing 1, the hollow upright post 14 is arranged on the step part 15, the spring 4 is arranged in the hollow upright post 14, a vertical groove 141 is arranged on the side wall of the hollow upright post 14, and reinforcing ribs 142 are arranged on two sides of the hollow upright post 14.

The vertical groove 141 extends upwards from the lower end of the hollow upright post 14, the cover 2 is provided with the swing rod part 22 extending into the vertical groove 141, the bottom surface of the cover 2 is provided with a reinforcing rib 221 connected with the tail end of the swing rod part 22 into a whole, as shown in fig. 7, the lower end of the spring 4 is propped against the swing rod part 22 through the ball 41, the ball 41 is a steel ball, and the ball 41 is in contact with the swing rod part 22 and the spring 4, so that the stress of the swing rod part 22 and the spring 4 is better and more uniform.
