Description

Technical Field

[0001] This utility model relates to the technical field of filtration equipment, and in particular to a structure for easy replacement of filter bottles and a water purifier thereof. Background Technology

[0002] With the development of water purifiers, the replacement of water purifier filters is becoming more consumer-driven. Therefore, the compatibility of the filter with the machine and the filter replacement structure is very important. A good filter replacement structure can better improve the consumer experience and enhance brand favorability.

[0003] Currently, filter cartridges usually need to be fixed to the main body or water circuit board. If the filter bottle is not fixed inside the machine, it will fall out and cause water to flow during normal use, making the machine unable to work. However, existing technology often uses a more complex structure to fix the filter bottle, which means that the filter bottle can only be removed with greater force.

[0004] Currently, when installing a water purifier filter cartridge, you generally need to first insert the entire filter cartridge stem into the water circuit board, then press down the filter cartridge clamp to lock the filter cartridge in place.

[0005] Existing water purifiers often use double O-ring seals at the water circuit board joint, which creates significant resistance during insertion. Users often cannot clearly perceive whether the filter is fully inserted, leading to frequent leaks due to incomplete filter insertion and resulting in complaints. Furthermore, the high internal pressure of the filter makes it difficult to remove, negatively impacting the consumer experience. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a filter bottle structure and water purifier that is easy to replace. The filter bottle can be disassembled and assembled by rotating the handle. The position of the handle determines the insertion or removal state of the filter bottle. The structure is simple, easy to operate, and has low manufacturing cost. It solves the problem of cumbersome and complicated disassembly and assembly of the filter bottle and the water circuit board, and the large space required.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] When the handle is in the first position, the first locking member pushes the second locking member upward and locks them in place, and the filter bottle engages with the water circuit plate.

[0012] When the handle is in the second position, the first locking member and the second locking member disengage, and the filter bottle detaches from the water circuit board by its own weight.

[0013] The above-mentioned easy-to-replace filter bottle structure includes a plurality of first insertion interfaces arranged longitudinally at the bottom of the water circuit plate and a plurality of second insertion interfaces arranged longitudinally at the top of the filter bottle.

[0014] When the first locking member and the second locking member lock together, the plurality of first plug-in interfaces respectively plug into the plurality of second plug-in interfaces.

[0015] The above-mentioned structure for easy filter bottle replacement includes a first locking member being a locking groove and a second locking member being a positioning post. The opening of the locking groove is provided with an inlet channel communicating with it.

[0016] As the handle moves from the second position to the first position, the positioning pin enters the locking groove from the guide channel;

[0017] The import channel is arranged in an arc shape.

[0018] In the aforementioned easy-to-replace filter bottle structure, there is a protruding portion between the inlet channel and the locking groove;

[0019] As the handle moves from the second position to the first position, the positioning post passes through the protrusion from the guide channel and enters the locking groove, and the positioning post is engaged with the protrusion for limiting.
