This utility model discloses an installation structure for a water purifier filter element, including a first sealing cover and a second sealing cover. The second sealing cover is detachably installed on the first sealing cover. Two stacked columnar shells are formed on the first sealing cover. A tube is provided on the upper columnar shell, and a connecting pipe is provided inside the second sealing cover, communicating with the connecting pipe. Two locking parts are symmetrically arranged on the side wall of the upper columnar shell. The locking parts are used to connect and fix with the second sealing cover. The locking parts are arc-shaped slide rails that surround and adhere to the side wall of the upper columnar shell. By redesigning the first and second sealing covers, their original threaded structure is changed to a rotating and lockable locking part. The original threaded structure requires multiple rotations to tighten, while the locking part only requires the second sealing cover and the first sealing cover to rotate half a turn to complete the tightening action, facilitating disassembly and replacement.

Description

Technical Field

[0001] This utility model relates to the field of water filtration technology, specifically to an installation structure for a water purifier filter element. Background Technology

[0002] Drinking water supply equipment is one of the essential basic living facilities in modern society. From the early simple water dispensers to the rapidly developing filtered drinking water machines in recent years, the functions and complexity of drinking water supply equipment have been continuously improving. Filter-type drinking water machines mainly rely on filter cartridges for physical filtration to remove various impurities from municipal water sources. Therefore, the filter cartridges are consumable components within the equipment and need to be replaced regularly to ensure water quality safety.

[0003] During the installation and use of a water purifier, the filter element needs to be installed on the filter element connector to secure it.

[0004] Current water purifier filter cartridges generally use a threaded tightening method, which allows for quick installation and removal of the connector between the filter cartridge and the inlet and outlet water pipes. However, the connector itself is inconvenient to disassemble and replace. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned above in the background technology and to propose an installation structure for water purifier filter cartridges.

[0006] The objective of this utility model can be achieved through the following technical solutions: An installation structure for a water purifier filter element includes a first sealing cover and a second sealing cover. The second sealing cover is detachably installed on the first sealing cover. Two stacked columnar shells are formed on the first sealing cover. A tube is provided on the upper columnar shell. A connecting pipe is provided inside the second sealing cover. The tube is connected to the connecting pipe. Two locking parts are symmetrically arranged on the side wall of the upper columnar housing. The locking parts are used to connect and fix with the second sealing cover. The locking parts are arc-shaped slide rails. The arc-shaped slide rails are attached to the side wall of the upper columnar housing. The head of the arc-shaped slide rail is flush with the top of the upper columnar housing, and the tail of the arc-shaped slide rail is flush with the top of the lower columnar housing. The inner wall of the second sealing cover is provided with fasteners that are rotatably engaged with the two locking parts.

[0007] As a further embodiment of this utility model, both of the columnar shells and the tube are integrally formed.

[0008] As a further embodiment of this utility model: the head of the arc-shaped slide rail has a downward-facing cut, the cut is an acute angle, the arc-shaped slide rail has a rounded corner at the arc transition between the cut and the waist of the arc-shaped slide rail, and the waist of the arc-shaped slide rail is recessed inward to form a recessed portion.

[0009] As a further embodiment of this utility model, the fastener and the locking part are seamlessly engaged.

[0010] As a further embodiment of this utility model: a limiting post protrudes outward on the side wall of the columnar shell between the two locking parts.

[0011] As a further embodiment of this utility model: a first limiting strip is formed on the inner wall of the second sealing cover at the tail end of the fastener.

[0012] As a further embodiment of this utility model: a second limiting strip is arranged around the outer wall of the connecting pipe, the second limiting strip is arranged vertically, and a plurality of third limiting strips are also formed on the inner wall of the second sealing cover at the fastener, the plurality of third limiting strips are arranged in a straight line.

[0013] As a further embodiment of this utility model, it also includes a filter element, wherein the first sealing cover is detachably and sealingly installed at the opening of the filter element.

[0014] The beneficial effects of this utility model are as follows: By designing the first and second sealing covers, the original threaded structure is changed into a rotating and lockable locking part. The original threaded structure requires multiple rotations to tighten, while the locking part only requires the second sealing cover to rotate half a turn with the first sealing cover to complete the tightening action, which facilitates disassembly and replacement.
