[0002] Currently, with people's increasing demands for environmental hygiene, cleaning carpets, sofas, curtains, and other surfaces has become an indispensable part of modern homes, businesses, and offices. Integrated suction cleaning equipment, as a cleaning tool combining water spraying and suction with wastewater recycling, has gradually become an important part of the cleaning industry due to its high cleaning efficiency. It sprays water or cleaning solution, scrubs stains, and uses powerful suction to draw wastewater and dust into a wastewater tank. This not only improves cleaning efficiency but also effectively removes moisture after cleaning, preventing carpets from remaining damp for extended periods and preventing the growth of bacteria and mold, making it an important tool for home cleaning. While current suction cleaning equipment on the market can complete basic cleaning tasks, it still has the following shortcomings in practical applications:

[0003] Existing integrated cleaning equipment features a fixed structural design and limited functionality, suitable only for specific cleaning needs. It cannot be adjusted to suit different cleaning objects, resulting in poor flexibility. Furthermore, different models need to be purchased for each cleaning requirement, increasing purchase and storage costs. Using multiple units also occupies limited storage space. In addition, existing equipment is bulky, and accessories are difficult to store. The equipment not only occupies significant space during use but is also inconvenient to store afterward, especially when multiple units are needed to handle different cleaning needs, further straining storage space. Moreover, existing cleaning equipment cannot adjust the handle height to accommodate different spaces or user heights, making it inconvenient to use and further limiting its adaptability to various scenarios.

[0004] Therefore, the structure of existing integrated extraction and washing cleaning equipment urgently needs to be optimized to solve the problems of traditional cleaning equipment having single function, large limitations, and poor adaptability. Utility Model Content

[0033] This application improves the clean water delivery and wastewater recycling structure. The cleaning head and cleaning brush are connected to the wastewater recycling pipe and the clean water outlet pipe via a selective connection structure, allowing the cleaning head and cleaning brush to be used interchangeably. This allows operators to freely change the cleaning head or cleaning brush according to different cleaning needs, such as carpet / sofa surface cleaning or curtain cleaning.

It solves the problem of configuring dedicated equipment for different cleaning needs in the prior art, reduces unnecessary space occupation, and lowers equipment purchase costs, making it highly economical.

[0034] Specifically, the sewage recovery pipe 32 and the clean water outlet pipe 22 are connected to the sewage tank 31 and the clean water tank 21 respectively through the sewage transfer pipe 33 and the clean water transfer pipe 23; in this embodiment, the sewage transfer pipe and the clean water transfer pipe are respectively T-shaped pipes in the prior art; the first end of the sewage transfer pipe 33 is connected to the sewage tank 31; the two ends of the sewage recovery pipe 32 are respectively connected to the second end of the sewage transfer pipe 33 and the cleaning brush plate 42; the first end of the clean water transfer pipe 23 is connected to the clean water tank 21; the two ends of the clean water outlet pipe 22 are respectively connected to the second end of the clean water transfer pipe 23 and the cleaning brush plate 42; the cleaning nozzle 41 is selectively connected to the third end of the sewage transfer pipe 33 through the nozzle clean water pipe 411 and the nozzle sewage pipe 412, and the water path switching between the cleaning nozzle 41 and the cleaning brush plate 42 is realized by the switching mechanism.

The outer cover of the storage cavity 121 is provided with a limiting structure to prevent the cleaning nozzle 41, the clean water pipe 411, and the wastewater pipe 412 from falling out. Specifically, this limiting structure can be a mesh bag, with limiting strips or similar structures used to fix the mesh bag around the opening of the storage cavity, preventing the cleaning nozzle components inside the storage cavity from falling out. By providing a storage cavity inside the cover specifically for accommodating the cleaning nozzle 41, the clean water pipe 411, and the wastewater pipe 412, and fixing the components with a limiting structure, the limited internal space of the equipment is effectively utilized, making the equipment's appearance simpler and more aesthetically pleasing, and facilitating subsequent maintenance and cleaning.
