Description

Technical Field

[0001] The utility model belongs to the technical field of filter element replacement structures, and particularly relates to a convenient filter element replacement control mechanism. Background Technique

[0002] In the water purifier structure, the filter element device plays a main filtering role. After the water purifier is used for a period of time, the filter element device needs to be replaced. The filtering ability of the filter element will decline as the use time goes by, but the whole water purifier and other components are still within the validity period. At this time, the water purifying ability of the water purifier can be restored by replacing the filter element, and the service life of the water purifier can be extended.

[0003] The filter cap of the existing filter element assembly can rotate relative to the housing of the whole water purifier. When the filter element needs to be replaced, the filter cap is rotated, and then the filter element assembly can be taken out from the whole water purifier. Although the filter element can be replaced in this way, after the filter element assembly is under water pressure, the inside of the filter element assembly is under pressure, and it is difficult for the filter cap to rotate relative to the housing of the whole water purifier, making disassembly and assembly difficult. In addition, when a new filter element is installed on the whole water purifier, there is an inconvenient assembly process between the filter cap and the whole water purifier body. Content of the Utility Model

The sliding buckle structure includes a slide rail arranged on the bottom surface of the bottom cover, installation grooves symmetrically opened on the bottom cover and located above both ends of the slide rail, L-shaped buckle pieces symmetrically penetrating through the two installation grooves and connected with the slide rail in a matching manner, and a spring arranged between the L-shaped buckle pieces; a rotating shaft installation plate is arranged on the upper surface of the installation groove. The L-shaped rotating shaft includes a connecting rod and a pushing rod. One end of the connecting rod horizontally passes through the rotating shaft installation plate and the decorative cover and is in transmission connection with the end of a handle located outside the decorative cover. The pushing rod extends downward and touches the arc-shaped panel of the L-shaped buckle piece facing the L-shaped rotating shaft; by flipping the handle, the pushing rod is driven to rotate, and the two L-shaped buckle pieces are pushed to move inward to realize the replacement of the filter element assembly.

[0007] Furthermore, a pressing plate is also arranged on the bottom surface of the bottom cover. The pressing plate is located between the two L-shaped buckle pieces. A through hole is formed between the pressing plate and the bottom surface of the bottom cover. The spring passes through the through hole to realize limiting.

[0008] Furthermore, a connecting column is arranged on the inner side of the L-shaped buckle piece, and both ends of the spring are inserted into the connecting column.

[0009] Further, the handle is semi-circular ring-shaped and symmetrically arranged. Gear structures are provided at both ends thereof, and the gear structures can mesh and push each other.

[0010] Further, insertion holes are provided inside both ends of the handle. One end of the connecting rod horizontally passes through the rotating shaft mounting plate and the decorative cover and is in transmission connection with the insertion holes.

[0011] Further, the outer end of the L-shaped buckle member passes through the bottom cover and extends outwards to be connected with the water purifier assembly.

[0012] Further, the L-shaped rotating shaft is integrally formed.

[0013] The beneficial effects of the present utility model are as follows:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the present utility model in conjunction with the accompanying drawings of the specification, but the protection scope of the present utility model is not limited thereto.

[0021] As Figure 1 shown, a filter element convenient replacement control mechanism is provided at the upper end of the filter element assembly 1, and includes a decorative cover 2, a bottom cover 3, a sliding buckle structure 4, two groups of L-shaped rotating shafts 5, two handles 6 and a pressing plate 7. The number of each group of L-shaped rotating shafts 5 is two, as Figures 2 to 4As shown in the figure, an installation space is formed between the decorative cover 2 and the bottom cover 3. Inside the installation space, there is a sliding buckle structure 4 and an L-shaped rotating shaft 5. The sliding buckle structure 4 includes a slide rail 41, two installation grooves 42, two L-shaped buckle members 43, and two springs 44. The slide rail 41 is provided on the bottom surface of the bottom cover 3. The two installation grooves 42 are symmetrically opened on the bottom cover 3 and are located above both ends of the slide rail 41. The outer sides of the vertical panels of the two L-shaped buckle members 43 are arc-shaped panels. The horizontal panels of the two L-shaped buckle members 43 pass through the installation grooves 42 on both sides and extend outwards through the bottom cover 3 to be connected to the water purifier assembly. And the lower surface of the L-shaped buckle member 43 is connected in cooperation with the slide rail 41 and can slide back and forth along the slide rail 41. Two connecting columns 431 are respectively provided on the inner sides of the two L-shaped buckle members 43. The two springs 44 are located between the two L-shaped buckle members 43, and the two ends of the springs 44 are correspondingly inserted into the connecting columns 431. On the bottom surface of the bottom cover 3, there is also a pressing plate 7. The pressing plate 7 is located between the two L-shaped buckle members 43 on both sides. Two through holes 71 are formed between the pressing plate 7 and the bottom surface of the bottom cover 3. The springs 44 pass through the through holes 71 to achieve up and down limit. On the upper surface of each of the two installation grooves 42, two rotating shaft mounting plates 421 are vertically provided. Through holes are formed on the rotating shaft mounting plates 421. The two handles 6 are symmetrically located outside the decorative cover 2. The handle 6 is in a semi-circular ring shape. Gear structures 61 are provided at both ends of the handle 6. The gear structures 61 can be engaged and push each other. Insertion holes 62 are provided on the inner sides of both ends of the handle 6. The L-shaped rotating shaft 5 is integrally formed. Each L-shaped rotating shaft 5 includes a connecting rod 51 and a pushing rod 52. One end of the connecting rod 51 horizontally passes through the through hole of the rotating shaft mounting plate 421 and the decorative cover 2 and is in transmission connection with the insertion hole 62. The other end is vertically connected to one end of the pushing rod 52. The other end of the pushing rod 52 extends downwards and touches the arc-shaped panel of the L-shaped buckle member 43 facing the L-shaped rotating shaft 5.

[0022] By lifting the handle 6, the L-shaped rotating shaft 5 in transmission connection with the handle 6 is driven to rotate, pushing the two L-shaped buckle members 43 to move inwards, and the springs 44 are compressed, so that the L-shaped buckle members 43 are disengaged from the water purifier assembly, so as to realize the replacement of the filter element assembly 1. At the same time, under the action of the springs 44, the L-shaped buckle members 43 can automatically reset to achieve quick installation.
