Description

Technical Field

[0001] The utility model relates to the technical field of water filters, in particular to a water filter convenient for maintenance. Background Art

[0002] After retrieval, the application number 202021952240.9 discloses a water purifier filter element convenient for maintenance, including a manual hoist body. One side of the manual hoist body is rotatably installed with a bracelet wheel through a rotating shaft. A manual chain is connected to the outside of the bracelet wheel. By fixedly installing a fixing block at the bottom of one side of the cover plate, a threaded rod is rotatably installed inside the fixing block. When lifting goods, the threaded rod is driven to rotate by rotating a knob, thereby driving a slider to move inside the fixing block.

[0003] During the use of the water purifier filter element convenient for maintenance in this patent application, a cylindrical positioning block is used to fix the filter element body under the elastic force of a compression spring in cooperation with a positioning ring sleeve. However, during such use, the components of the device are connected under the elastic force of the compression spring, and this connection method has poor stability. When the water to be filtered enters the inside of the cylindrical positioning block through the water inlet pipe, due to the impact of the water on the filter element body, a reaction force is formed to push the cylindrical positioning block, and the cylindrical positioning block will compress the compression spring to generate vibration, which is likely to damage the device and reduce the service life of the device. Therefore, we propose a water filter convenient for maintenance. Summary of the Utility Model

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a water filter convenient for maintenance.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme. A water filter convenient for maintenance includes a device housing, a protective top cover arranged on the top of the device housing, and a filter element body arranged inside the device housing. The middle part of the top end of the protective top cover is fixedly sleeved with a water inlet pipe, and the middle part of the bottom end of the device housing is fixedly sleeved with a water outlet pipe. The top end of the device housing bends outward to form a mounting edge. Four fixing threaded holes are formed in the top wall surface of the mounting edge at equal intervals in a circular shape. A fixing mechanism is arranged on the bottom wall surface of the protective top cover. The fixing mechanism includes four fixing bolts rotatably connected to the edge position of the bottom wall surface of the protective top cover. The bottom ends of the four fixing bolts correspond to the positions of the four fixing threaded holes and are threadedly installed. A diamond-shaped driving groove is formed at the inner edge position of the protective top cover. A driving mechanism for driving the four fixing bolts to rotate synchronously is arranged inside the driving groove. The driving mechanism is rotatably connected to four synchronous rotating shafts at the four corner positions inside the driving groove. The top ends of the four synchronous rotating shafts penetrate the bottom inner wall surface of the driving groove and are fixedly connected to the top ends of the four fixing bolts.

[0006] Furthermore, a cylindrical positioning block fixedly connected to the middle of the bottom wall surface of the protective top cover is clamped at the top end of the filter element body, and the bottom end of the water inlet pipe is fixedly sleeved into the middle of the top wall surface of the cylindrical positioning block.

[0007] Furthermore, a positioning ring sleeve fixedly connected to the bottom wall surface of the equipment housing is sleeved at the bottom of the outer wall surface of the filter element body.

[0008] Furthermore, a sealing ring that fits the corresponding position of the bottom wall surface of the protective top cover is fixedly connected to the edge position of the top wall surface of the equipment housing.

[0009] Furthermore, the four synchronous rotating shafts are distributed in an annular and equally spaced state and are respectively on the same axis as the four fixing bolts.

[0010] Furthermore, synchronous sprockets are fixedly installed on the outer walls of one ends of the four synchronous rotating shafts located inside the driving grooves, and a synchronous chain is connected between the four synchronous sprockets.

[0011] Furthermore, the top end of the synchronous rotating shaft located on the left side penetrates through the corresponding position of the top inner wall surface of the driving groove and extends to the outside, and a rotating block is fixedly installed.
