Description

Technical Field

[0001] This application relates to the field of drinking water equipment technology, specifically to a water dispenser that facilitates filter replacement. Background Technology

[0002] Water dispensers, as a common type of drinking water equipment, are usually used in conjunction with water purifiers to heat or cool filtered water to meet users' immediate drinking water needs. The filter cartridge is a crucial component in a water dispenser, used to filter impurities and improve water quality. As the usage time increases, the filtration efficiency of the filter cartridge gradually decreases, therefore, it needs to be replaced regularly.

[0003] Currently, most water dispenser filter replacement methods on the market are quite cumbersome. Some dispensers have filters located deep inside the machine, requiring disassembly of the outer casing for replacement, which is complex and can easily damage other internal components. Other dispensers have poorly designed filter installation structures, requiring specialized tools for replacement, causing significant inconvenience and reducing the user experience. Therefore, designing a water dispenser with a simple structure that allows users to easily replace the filters themselves is of significant practical importance. Summary of the Invention The purpose of this utility model is to provide a pipeline machine that facilitates filter replacement. By setting the end face of the filter assembly to be coplanar with the side plate of the machine body and optimizing the installation structure of the filter assembly, the filter can be quickly disassembled and assembled, improving user convenience and equipment aesthetics.

[0004] To achieve the above objectives, the following technical solution is provided: A pipeline machine that facilitates filter replacement includes: a body and a filter assembly, pipeline, heating assembly, and water pump disposed inside the body. The filter assembly, heating assembly, and water pump are connected by the pipeline, and one end face of the filter assembly is coplanar with the side plate of the body.

[0005] Furthermore, the filter element assembly includes a filter element mounting cavity body, a filter element mounting cavity fixing part disposed at one end of the filter element mounting cavity body, an openable cavity door disposed at the other end of the filter element mounting cavity body, and a filter element disposed inside the filter element mounting cavity body, wherein the cavity door is coplanar with the side plate of the machine body.

[0006] Furthermore, the filter element mounting cavity fixing part is provided with a filter element inlet, a filter element outlet and a fixing ear. The filter element inlet and the filter element outlet are respectively sealed and connected to the inlet end and outlet end of the filter element, and the fixing ear is fixedly connected to the inner side wall of the machine body.

[0007] Furthermore, the heating assembly includes a heating element and a heating chamber, and the filter assembly, heating chamber, water pump, and heating element are connected in series via pipelines.

[0008] Furthermore, it also includes a solenoid valve, which is connected to the upstream water path of the filter element assembly via a pipeline.

[0009] Furthermore, it also includes a water distribution valve, which is installed between the filter element assembly and the heat exchanger via a pipeline.

[0010] Furthermore, the machine body has a filter element assembly mounting cavity inside, the inner wall of the filter element assembly mounting cavity is provided with a guide rail, and the outer wall of the filter element mounting cavity body is provided with a sliding groove that cooperates with the guide rail. The filter element assembly is pulled out or pushed in along the guide rail direction through the sliding groove.

[0011] The combination of the positioning guide rail and the slide groove provides guidance for the installation and disassembly of the filter element assembly, ensuring the accuracy and smoothness of the filter element installation, while also enhancing the stability of the filter element inside the machine.

[0012] Furthermore, the cavity door is detachably connected to the filter element mounting cavity body via a threaded or snap-fit ​​structure, and a sealing gasket is provided on the inner side of the cavity door.

[0013] Furthermore, the cavity door is provided with a disassembly part.

[0014] Furthermore, the disassembly part is a cross-shaped or straight groove.

[0015] This technical solution features a filter cartridge installation cavity on the side of the machine body, along with an openable cavity door and a quick-connect structure. This allows users to easily replace the filter cartridge by simply opening the cavity door and pulling it out from the side, without disassembling the machine body. This simple and convenient operation greatly improves the efficiency of filter cartridge replacement and enhances the user experience. The filter cartridge installation cavity fixing part is firmly connected to the machine body via fixing ears, and combined with the guide rail slide structure, it ensures the stability of the filter cartridge assembly during equipment operation and prevents the water circuit connection from loosening due to vibration.
