The invention discloses a secret connecting method for fixing a shell and an engine base of the water purifier. The method comprises the steps of arranging a connecting structure, fixing the engine base of a filter and a fixed standard element. The method also comprises the steps of arranging an external thread structure, a shell of a through hole and an internal thread decoration cover. The external thread structure is disposed in the periphery of the through hole; the fixed standard element penetrates through the through hole and is connected to the engine base connecting structure to so as to connect and fix the shell on the engine base; and the internal thread decoration cover is connected to the external thread structure on the shell in a fitting manner to form a secret connecting structure of the cover and the fixed standard element. The secret connecting method arranges the position of a shell installation hole in consideration of meeting mechanical properties of the shell of the water purifier, without worrying to destroy a control surface or the whole shaping and beauty of the shell, and integrates the secret connecting structure of the cover and the fixed standard element with the control surface or the shell together.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the fixing aspect of the shell of the water purifier. Background technique [0002] At present, with the varieties and styles of water purifiers coming out endlessly, they have greatly satisfied the needs of consumers in terms of functions. However, for the under-cabinet model placed under the sink, since it can only be placed on both sides under the sink cabinet, the width is less than 20 cm, so the width requirements for the water purifier are very strict, especially when the water purifier adopts double When the structure of the filter cartridge is discharged, it is very difficult to set up two filter cartridges with a limited width, not to mention the housing.

However, for the under-cabinet model placed under the sink, since it can only be placed on both sides under the sink cabinet, the width is less than 20 cm, so the width requirements for the water purifier are very strict, especially when the water purifier adopts double When the structure of the filter cartridge is discharged, it is very difficult to set up two filter cartridges in the original limited width, not to mention the housing

However, because the outline of the plastic cap destroys the overall shape and appearance of the control panel or housing, and is difficult to integrate, it seriously affects the shape and appearance of the water purifier product, and has become a taboo in product industrial design.

The above defects and deficiencies seriously affect the design and manufacture of water purifier products
