Description

Technical Field

[0001] This utility model belongs to the field of toilet equipment technology, and in particular relates to a jetting device for a high-speed rail toilet. Background Technology

[0002] The ejector of the toilet in high-speed rail is one of the core components of the vacuum toilet system. Its main function is to efficiently collect and process excrement using the principle of positive and negative pressure. When flushing, the ejector uses positive pressure to quickly push the excrement into the pipe, while the negative pressure generated by the vacuum device forcefully sucks the waste into the collection tank at the bottom of the carriage. This design ensures that excrement is completely collected during train operation, avoiding direct discharge onto the tracks, and is disposed of by professionals after the train reaches its destination.

[0003] However, existing toilet sprayers lack a filtration system, allowing larger foreign objects or fixed particles to directly enter the sprayer or piping system, increasing the risk of blockage and affecting the normal operation of the entire toilet system. Furthermore, the lack of filtration means that impurities will directly enter the subsequent sewage system, which may lead to equipment wear or failure after long-term operation, increasing the frequency of maintenance. Therefore, a new type of toilet sprayer for high-speed rail is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a high-speed rail toilet flushing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0015] This invention features a filtration structure comprising a main pipe, branch pipes, filter tubes, and filter elements. The main pipe is connected to the branch pipes, which in turn are connected to the filter tubes. The main pipe is connected to the ejector body at its end furthest from the branch pipes. In use, the ejector body, mounting cylinder, and ejector head are interconnected. Liquid in the ejector body is pumped through a vacuum pump to the main pipe, then flows into the branch pipes connected to the main pipe, and enters the filter element in the filter tube. The liquid filtered by the filter element is ejected from the ejector body through the ejector head. Impurities or solid particles in the liquid remain in the filter element, preventing larger foreign objects or fixed particles in the liquid from clogging the ejector head, thus preventing wear or malfunction of the equipment and extending its service life.

The liquid in the injector body 11 is pumped by a vacuum pump to the main pipe 21, and then flows into multiple branch pipes 22 connected to the main pipe 21, and enters the filter element 24 in the filter tube 23. The liquid filtered by the filter element 24 is sprayed out of the injector body 11 through the injection head 13. At this time, impurities or solid particles in the liquid remain in the filter element 24. By setting the filtration structure 2, larger foreign objects or fixed particles in the liquid are prevented from clogging the injection head 13, so as to prevent wear or failure of the equipment and extend the service life of the equipment.

[0042] In addition, when the liquid flows at high speed in the main pipe 21 and the branch pipe 22, the spring 254 is continuously compressed and rebounded in the insertion groove 261. By setting the spring 254, the vibration caused by the water flow impact on the equipment is reduced, and the service life of the equipment is extended.

[0043] When the filter element 24 needs to be replaced after a period of use, the user first separates the injector body 11 from the mounting cylinder 12; then rotates the fixing cylinder 15 to make the fixing cylinder 15 separate from the sealing plate 14 and the main pipe 21, and then removes the sealing plate 14. At this time, the filter element 24 can be taken out and replaced. The operation is simple.
