Background
Tap water obtained at home usually is transported to home through a series of treatment procedures, namely water taking, water guiding, water purifying and water delivering. Since a pipeline for transporting tap water may be damaged due to old use over the years, so that the tap water is easily subjected to secondary pollution during transportation, it is common to install a water filter in a household to primarily filter, for example, heavy metals or other chemicals, and then to boil the heavy metals or other chemicals at a high temperature for safe drinking. The filter element in a water filter therefore plays an important role and must be replaced periodically to maintain good water quality. Referring to fig. 1, a conventional water filter 9 includes a base 91, a housing 92, and a fixing device 93. The base 91 and housing 92 house a filter cartridge (not shown) that must be removed for replacement when the filter cartridge has reached a predetermined useful life. Before the filter element is taken out, the fixing device 93 must be loosened, and then the shell 92 is separated from the base 91, so that the filter element can be taken out and replaced. Most of the conventional fixing devices are configured to screw and fix two ends of an iron ring 932 by a bolt 931, so that it takes much effort and time to rotate the bolt 931 to disassemble the fixing device 93 every time the filter element is replaced, which is inconvenient in operation.

Referring to fig. 2 and 3, an embodiment of the water filter 100 of the present invention includes a base 1, a sealing gasket 2, a filter element 3, a housing 4, and a fixing device 5. In the present embodiment, the base 1 is made of stainless steel, and includes a bottom portion 11, a body portion 12, an engaging wall portion 13, and a stopping wall portion 14. The bottle bottom 11 is circular, the bottle body 12 extends upwards from the periphery of the bottle bottom 11, and the bottle bottom 11 and the bottle body 12 define a storage space 15 together. The engaging wall 13 is circumferentially connected to the top edge of the body 12 and defines a mouth 16 communicating with the storage space 15. The stopper wall portion 14 projects radially outwardly from the junction of the body portion 12 and the engagement wall portion 13. The sealing washer 2 is sleeved on the connecting wall 13 and abuts against the stopping wall 14. The filter element 3 is arranged in the storage space 15 via the opening 16.
The housing 4 is detachably connected to the base 1, and includes a housing 41, a water inlet pipe 42, and a water outlet pipe 43. The housing 41 is bell-shaped and made of stainless steel, and has an inner shell surface 411 and a flange portion 412 defining an opening 413 and bent outwardly in an arc shape. The inner shell surface 411 is slightly inclined, so that the aperture of the housing 41 is tapered in a direction away from the flange portion 412, and the inner shell surface 411 has a first peripheral surface portion 411a adjacent to the opening 413 and a second peripheral surface portion 411b away from the opening 413 and having an inner diameter smaller than the first peripheral surface portion 411 a. When the housing 4 covers the base 1 and the filter element 3, the engaging wall 13 of the base 1 passes through the opening 413 and extends into the housing 4 along the first peripheral surface portion 411a of the inner housing surface 411, and is tightly fitted to the second peripheral surface portion 411b of the inner housing surface 411. The shape of the flange portion 412 matches the shape of the stop wall portion 14 of the base 1, so that the flange portion 412 can be connected to the outer surface of the stop wall portion 14 when the flange portion 412 is pressed against the sealing gasket 2 and covers the stop wall portion 14 together. The inlet pipe 42 and the outlet pipe 43 are each adapted to be connected to a line (not shown) so that tap water can enter the filter element 3 through the inlet pipe 42 and be output through the outlet pipe 43.
The fixing device 5 is detachably disposed at the joint of the base 1 and the housing 4. Referring to fig. 4 to 6, in the present embodiment, the fixing device 5 includes three arc-shaped members 51, two pivot modules 52, and a quick release module 53. The arc members 51 together enclose a circular ring structure, and are used to clamp the stopping wall portion 14 of the base 1 and the flange portion 412 of the housing 4 to be fixed at the joint of the base 1 and the housing 4. Each arcuate member 51 has a first end 511 and a second end 512 at opposite ends, and an inner side 513 and an outer side 514 at opposite sides. The inner side surface 513 has a groove 513a formed along the inner periphery of the arc member 51 for receiving the retaining wall 14 and the flange portion 412. The outer side surface 514 has a rib 514a formed along the outer periphery of the arc member 51. For clarity, the curved member 51 is divided into a first curved member 51a, a second curved member 51b, and a third curved member 51 c.
The pivot modules 52 are disposed at the first end 511 and the second end 512 of two adjacent arc-shaped members 51, one of the pivot modules 52 is connected to the second end 512 of the first arc-shaped member 51a and the first end 511 of the third arc-shaped member 51c, and the other pivot module 52 is connected to the second end 512 of the third arc-shaped member 51c and the first end 511 of the second arc-shaped member 51b, so that the first arc-shaped member 51a, the second arc-shaped member 51b and the third arc-shaped member 51c can pivot relatively to each other. In detail, each pivot module 52 includes two connecting bases 521 and a pivot member 522 pivotally disposed on the connecting bases 521. Two connecting bases 521 of one of the pivot modules 52 are correspondingly disposed at the second end 512 of the first arc-shaped member 51a and the first end 511 of the third arc-shaped member 51c, two connecting bases 521 of the other pivot module 52 are correspondingly disposed at the second end 512 of the third arc-shaped member 51c and the first end 511 of the second arc-shaped member 51b, and the connecting bases 521 are disposed on the protruding rib 514a of the arc-shaped member 51. The advantage of this design is that when the arc-shaped members 51 are clamped between the base 1 and the housing 4, the gap between the first end 511 and the second end 512 of two adjacent arc-shaped members 51 is smaller, so that the circular structure surrounded by the arc-shaped members 51 can clamp the base 1 and the housing 4 more tightly. In other embodiments, the number of the arc-shaped members 51 may be only two (the first arc-shaped member 51a and the second arc-shaped member 51b), the number of the pivot module 52 may be only one, and the pivot module 52 is connected to the second end 512 of the first arc-shaped member 51a and the first end 511 of the second arc-shaped member 51 b.
The quick release module 53 is used for relatively fixing the first end 511 of the first arc-shaped part 51a and the second end 512 of the second arc-shaped part 51b, so that the first arc-shaped part 51a, the second arc-shaped part 51b and the third arc-shaped part 51c can jointly urge the butt joint of the base 1 and the housing 4. In detail, the quick release module 53 includes an anchor hook member 531 and a fastener member 532. In this embodiment, the anchor hook member 531 has a long plate 531a fixed to the second end 512 of the second arc member 51b and located on the protruding rib 514a, and a barb 531b bent and extended from one end of the long plate 531 a. In other embodiments, the anchor hook member 531 can be integrally formed with the second end 512 of the second arcuate member 51b, and need not be barb-shaped, so long as it can be detachably connected to the fastener set 532. The fastener set 532 is disposed at the first end 511 of the first arc-shaped member 51a, and has a bottom plate 533, a pull handle 534, and a collar 535.
Referring to fig. 7, the bottom plate 533 is fixed to the protruding rib 514a of the first arc-shaped member 51a, and has an arc-shaped plate 533a attached to the protruding rib 514a, and a positioning portion 533b formed on an outer surface of the plate 533 a. One end of the pulling handle 534 is pivotally disposed at an end of the plate 533a close to the second arc-shaped member 51b, and has a first side handle portion 534a, two second side handle portions 534b bent and extended from two opposite sides of the first side handle portion 534a, and a joint portion 534c formed on the first side handle portion 534a, wherein the first side handle portion 534a and the second side handle portion 534b together define a receiving space 534 d. The pulling handle 534 can be pivotally close to or far from the outer side surface 514 of the first arc-shaped member 51a, and when the pulling handle 534 pivots towards the direction close to the outer side surface 514 of the first arc-shaped member 51a and is close to the outer side surface 514, the positioning portion 533b can extend into the accommodating space 534d and be clamped with the joint portion 534c, so that the pulling handle 534 is fixed to the first arc-shaped member 51a, and the arc-shaped member 51 is relatively fixed. In other embodiments, the pull tab 534 can be directly pivoted to the first end 511 of the first arc-shaped member 51 a.
One end of the collar 535 is pivotally connected to the second side handle 534b of the pull handle 534, and the other end is detachably sleeved on the barb 531b of the anchor hook 531. In detail, when the collar 535 is sleeved on the anchor hook member 531 and drives the pull handle 534 to pivot towards the direction close to the outer side surface 514 of the first arc-shaped member 51a, the pull handle 534 will drive the collar 535, the collar 535 will drive the anchor hook member 531, so that the second end 512 of the second arc-shaped member 51b is driven by the anchor hook member 531 to be close to the first end 511 of the first arc-shaped member 51a, and the arc-shaped member 51 is wound into a circular structure to be pressed against the butt joint of the base 1 and the housing 4. When a user wants to replace the filter element 3, the user only needs to pull the pull handle 534 in a direction away from the outer side surface 514 of the first arc-shaped member 51a to unlock the positioning portion 533b, and then pivot the pull handle 534 in a direction away from the outer side surface 514 of the first arc-shaped member 51a continuously, so that the loop 535 and the anchor hook member 531 are released relatively, and the fixing device 5 can be taken down to separate the housing 4 and the base 1 from each other, thereby replacing the filter element 3.
In summary, the water filter 100 of the present invention drives the ring 535 to be fastened or separated to the anchor member 531 by simply operating the pull handle 534 in the quick-release module 53, so that the fixing device 5 can be quite conveniently fixed or disassembled to the base 1 and the housing 4 of the water filter, and the effort and time required for rotating the bolt in the past are saved, thereby achieving the purpose of the present invention.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
