[0019] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.
[0020] As attached Figure 1-4As shown, this utility model provides a rubber part for unclogging sewer pipes, including an upper shell 1 and a handle 2. The upper shell 1 is a gradually expanding shape with a bottom diameter greater than the top diameter. The side walls of the upper shell 1 have a uniform thickness and are stepped shapes that expand downwards. An air cavity 11 is formed inside the upper shell 1 to adapt to the side walls of the upper shell 1. An opening is provided at the bottom of the upper shell 1, and the air cavity 11 communicates with the outside through the opening. A connector 3 is provided at the top of the upper shell, and a threaded hole is provided at the top of the connector 3. The bottom of the handle 2 is provided with a thread that adapts to the threaded hole, so that the handle 2 can be screwed into the threaded hole and connected to the upper shell 1.
[0021] In actual use, the user first holds the handle 2 and covers the drain pipe inlet with the upper housing 1, then presses the device downwards, causing the upper housing 1 to compress downwards and allowing air from the air chamber 11 to enter the drain pipe and squeeze the blockage downwards. Next, the user quickly pulls the handle 2 back, allowing the upper housing 1 to return to its initial shape, creating a vacuum in the drain pipe. The blockage in the drain pipe is then subjected to an upward force under air pressure. This process is repeated until the blockage in the drain pipe loosens and leaves the drain pipe. During use, the stepped sidewalls of the upper housing 1 deform more easily, making it easier for users, especially the elderly and children with less strength, to use the device.
[0022] In this embodiment, as a preferred implementation, a lower shell 4 is also provided at the bottom of the upper shell 1. The side wall of the lower shell 4 is a stepped shape that tapers downwards. The bottom of the lower shell 4 is provided with an air hole with a diameter smaller than the opening. The air cavity 11 is connected to the outside through the air hole. The additional lower housing 4 increases the air capacity of the device, allowing more air to be introduced into the drain pipe when the device is pressed down. The smaller diameter vent hole concentrates the gas entering the drain pipe, resulting in a faster flow rate. During pressing, the stepped lower housing 4 deforms, increasing the contact area between the lower housing 4 and the pipe opening, thus improving the sealing of the drain pipe and ensuring a negative pressure effect during pressing. Furthermore, the upper housing 1 and lower housing 4 deform simultaneously during pressing, further reducing the force required by the user. In use, a portion of the lower housing 4 can also extend into the drain pipe, sealing it by pressing against the inner wall of the drain pipe with the side walls of the upper housing 1 and lower housing 4. This brings the vent hole closer to the blockage, applying a stronger force to the blockage and making it easier to loosen, thus improving user convenience. An annular extension 41 can also be provided on the vent hole at the bottom of the lower housing 4 to further extend the vent's insertion distance into the drain pipe, allowing the device to generate stronger air pressure on the blockage.
[0023] In this embodiment, as a preferred implementation, the connection between the upper housing 1 and the lower housing 4 can be made of a relatively hard rubber material. The bottom of the upper housing 1 is provided with a threaded groove, and the top of the lower housing 4 is provided with a thread that matches the threaded groove. The upper housing 1 and the lower housing 4 are detachably and sealingly connected. Users can choose whether to install the lower housing 4, or they can remove the lower housing after use to facilitate cleaning of the inside of the device.
[0024] In this embodiment, as a preferred implementation, the bottom of the connector 3 is evenly distributed with multiple first ribs 5. One end of the first rib 5 is fixedly connected to the connector 3, and the other end is fixedly connected to the inner wall of the upper housing 1. The first rib 5 is located inside the air cavity 11. This strengthens the connection between the connector 3 and the upper housing 1, preventing damage to the connection between the upper housing 1 and the connector 3 due to excessive force during use.
[0025] In this embodiment, as a preferred implementation, a support assembly is also provided inside the air cavity 11. The support assembly includes an annular plate 12 and a second rib 13. The annular plate 12 is fixedly connected to the connector 3. The first rib 5 is located inside the annular plate 12 and fixedly connected to the inner wall of the annular plate 12. The second ribs 13 are evenly distributed on the outer wall of the annular plate 12. One end of the second rib 13 is fixedly connected to the annular plate 12, and the other end is fixedly connected to the inner wall of the lower housing 4. Thus, the support assembly provides a certain constraint on the direction of force applied to the handle 2, preventing the handle 2 from tilting during use and causing excessive force on one side of the upper housing 1, which could lead to damage to the upper housing 1.
[0026] In this embodiment, as a preferred implementation, the handle 2 is a manual telescopic rod or an electric telescopic rod. This allows the user to easily adjust the length of the handle 2 according to their height, making the device more convenient to use and also facilitating its storage when not in use.
[0027] The above description is only a preferred embodiment of the present utility model and not all embodiments. Anyone should know that structural changes made under the guidance of the present utility model are protected by the present utility model. All technical solutions that are the same as or similar to the present utility model are within the scope of protection of the present utility model.
