Description

Technical Field

[0001] The utility model relates to a connection structure used on a water purification device, in particular to a buckle-type quick-connection structure of the water purification device. Background Art

[0002] Similar structures on existing water purification equipment are mostly threaded structures, which require long-term rotation when installing or disassembling. In particular, most water purification equipment is installed in cabinets with limited operating space. Long-term rotation operation is very inconvenient and brings great consumption and inconvenience to operators, which affects the quality of the entire water purification equipment to a certain extent. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a snap-on quick-connect structure for water purification equipment in view of the deficiencies in the prior art.

[0004] In order to achieve the above purpose, the measures taken by the utility model are:

[0005] A snap-on quick-connect structure for a water purification device, comprising a filter cover and a cover ring that are detachably connected to each other, wherein four snap-on convex ribs are evenly arranged on the outer wall of the filter cover connection portion of the filter cover along the circumferential direction, and an L-shaped opening slot that cooperates with the snap-on convex rib is opened on the inner wall of the cover ring;

[0006] The inner section of the L-shaped opening slot is tilted upward at an angle;

[0007] The buckle convex rib is provided with a first inclined surface at one end thereof facing the inner section of the buckle groove;

[0008] The buckle convex rib gradually becomes lower from one end of the first inclined surface to the other end;

[0009] The opening of the L-shaped opening slot is provided with a second inclined surface and a third inclined surface;

[0010] The snap-on quick-connect structure of the water purification equipment is applied to a filter bottle or a pre-filter.

[0011] The beneficial effects of the utility model include novel structure, quick disassembly, good stability, convenience for quick replacement of the filter element, and improved product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the exploded structure of the utility model. DETAILED DESCRIPTION

[0013] A snap-on quick-connect structure for a water purification device comprises a filter cover 1 and a cover ring 2 which are detachably connected to each other. Four snap-on ribs 102 are evenly arranged on the outer wall of a filter cover connecting portion 101 of the filter cover 1 along the circumferential direction, and an L-shaped open slot 201 cooperating with the snap-on rib 102 is opened on the inner wall of the cover ring 2.

[0014] like Figure 1 As shown, when the filter cover 1 and the cover ring 2 are quickly connected to each other, the buckle convex rib 102 of the filter cover 1 is aligned with the opening of the L-shaped opening slot 201, and the buckle convex rib 102 slides from the opening into the L-shaped opening slot 201. The filter cover 1 is rotated clockwise, and the buckle convex rib 102 slides to the slot inner section 202 of the L-shaped opening slot 201, completing the quick connection between the filter cover 1 and the cover ring 2. When disassembling, just rotate the filter cover 1 in the direction of rotation. The two can be quickly installed or disassembled.

[0015] The inner section 202 of the L-shaped opening slot 201 is tilted upward at an angle. After the two are connected, the locking is more secure.

[0016] The buckle rib 102 is provided with a first inclined surface 103 at one end thereof facing the inner section 202 of the buckle slot.

[0017] The buckle convex rib 102 gradually becomes lower from one end of the first inclined surface 103 to the other end. This structure cooperates with the inner section 202 of the card slot that is tilted upward at an angle, so that the locking is more secure and accidental loosening is avoided.

[0018] The opening of the L-shaped opening slot 201 is provided with a second inclined surface 203 and a third inclined surface 204. The design of the inclined surfaces facilitates the sliding fit between the buckle rib 102 and the L-shaped opening slot 201.

[0019] The snap-on quick-connect structure of the water purification equipment is applied to a filter bottle or a pre-filter.
