[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.
[0028] Please see Figures 1 to 6 As shown, this utility model provides a filter bottle 100 for easy replacement of filter elements, including a bottle body 10, a bottle cap 20 and a locking mechanism. The bottle cap 20 is detachably assembled onto the bottle body 10 through the locking mechanism.
[0029] The upper end of the bottle body 10 is open to allow the filter element to be inserted. The lower end of the bottle body 1 is provided with several connectors 13 so that water can flow into the bottle body 10 and flow out after being purified and filtered by the filter element. The bottle body 10 is provided with a first locking hole 11 and a second locking hole 12, which correspond to each other and are close to the opening.
[0030] The bottle cap 20 can be inserted into the upper end of the bottle body 10 to close the opening. It has a first through hole 21 and a second through hole 22 that are arranged opposite to each other. When the bottle cap 20 is assembled on the bottle body 10, the first through hole 21 is connected to the first locking hole 11, and the second through hole 22 is connected to the second locking hole 12.
[0031] The locking mechanism includes a drive member 30, a first locking member 40, a transmission member 50, and a second locking member 60 connected in sequence. The locking mechanism is located on the bottle cap 20. Specifically, the bottle cap 20 includes a base 23 and a cap body 24 covering the base 23. The base 24 has a transversely penetrating channel 25, which is straight. A first through hole 21 and a second through hole 22 are located on the cap body 24. When the cap body 24 is placed on the base 24, the first through hole 21 and the second through hole 22 are located at opposite ends of the channel 25, meaning the first through hole 21, the channel 25, and the second through hole 22 are sequentially and linearly connected. The drive member 30 is located above the bottle cap 20 and partially extends into the channel 25. The drive member 30 has a lever through hole 31 for easy finger manipulation. The drive member 30 is hinged to the bottle cap 20 so that the drive member 30 can rotate relative to the bottle cap 20. The channel 25 contains the first locking member 40, the transmission member 50, and the second locking member. 60. The first locking member 40 is located on the rotation trajectory of the driving member 30. When the driving member 30 rotates, it can drive the first locking member 40 to slide along the channel 25. The first locking member 40 drives the second locking member 60 to slide through the transmission member 50, so that the first locking member 40 and the second locking member 60 can move closer or further away from each other. When the first locking member 40 and the second locking member 60 move closer to each other, the first locking member 40 can retract from the first locking hole 11 into the channel 25, and the second locking member 60 can retract from the second locking hole 12 into the channel 25. At this time, the bottle cap 20 and the bottle body 10 can be separated for filter replacement. When the first locking member 40 and the second locking member 60 move further away from each other, the first locking member 40 passes through the first through hole 21 and enters the first locking hole 11, and the second locking member 60 passes through the second through hole 22 and enters the second locking hole 12. The bottle body 10 and the bottle cap 20 are locked, and the assembly is completed.
[0032] The first locking member 40 includes a first body 41 and a first locking tongue 42. The first body 41 abuts against the driving member 30. The first locking tongue 42 is adapted to the first through hole 21 and can pass through the first through hole 21 and enter the first locking hole 11. The second locking member 60 includes a second body 61 and a second locking tongue 62. The second locking tongue 62 is adapted to the second through hole 22 and can pass through the second through hole 22 and enter the second locking hole 12.
[0033] The width of the first body 41 is greater than the width of the first locking tongue 42, the width of the first body 41 is greater than the width of the first through hole 21, the width of the second body 61 is greater than the width of the second locking tongue 62, and the width of the second body 61 is greater than the width of the second through hole 22. This arrangement ensures that the first locking member 40 and the second locking member 60 can slide along the channel 25 without disengaging from the bottle cap 20.
[0034] In this embodiment, the channel 25 is covered with a pressure cover 70, which limits the first locking member 40 and the second locking member 60 in the longitudinal direction to prevent the first locking member 40, the second locking member 60 and the transmission member 50 from disengaging from the channel 25.
[0035] An elastic element abuts between the first locking member 40 and the channel 25 and / or between the second locking member 60 and the channel 25. The elastic element is used to drive the first locking member 40 and the second locking member 60 away from each other. In this embodiment, an abutment seat 26 is provided in the channel 25, and an elastic element is provided between the abutment seat 26 and the second body 61. The elastic element is preferably a spring. The spring is used to drive the first locking tongue 42 and the second locking tongue 62 to pass through the first through hole 21 and the second through hole 22, respectively. Of course, an elastic element can also be provided between the abutment seat 26 and the first body 41, or even the abutment seat 26 can be a pair, with elastic elements provided between the abutment seat 26 and the first body 41 and between the abutment seat 26 and the second body 61, respectively. In order to better set the elastic element, both the first body 41 and the second body 61 are provided with receiving through holes 44 and 64, and abutting posts 45 and 65 are provided in the receiving through holes. The abutting seat 26 extends into the corresponding receiving through holes 44 and 64, and the spring abuts between the abutting seat 26 and the abutting posts 45 and 65.
[0036] A rotating shaft 27 is provided inside the channel 25. The rotating shaft 27 is vertically arranged and coincides with the central axis of the bottle body 10. The transmission component 50 is rotatably mounted on the rotating shaft 27, so that the transmission component 50 can rotate relative to the channel 25. The transmission component 50 includes a first end 51 and a second end 52 that are far apart from each other. The first end 51 is connected to the first locking component 40, and the second end 52 is connected to the second locking component 60. When the transmission component 50 rotates, it can drive the first locking component 40 and the second locking component 60 to move closer to each other or further apart.
[0037] The first locking member 40 and the second locking member 60 are respectively provided with transmission grooves 43 and 63 adapted to the first end 51 and the second end 52. The first end 51 and the second end 52 are both locked in the transmission grooves 43 and 63. In this embodiment, the first end 51 and the second end 52 are both provided with locking pins 53. The locking pins 53 are adapted to the transmission grooves 43 and 63 and are locked in the transmission grooves 43 and 63. The first body 41 and the second body 61 are close to each other. The transmission groove 43 is located at the end of the first body 41 close to the second body 61, and the transmission groove 63 is located at the end of the second body 61 close to the first body 41. The rotating shaft 27 is located in the middle of the first end 51 and the second end 52. The transmission grooves 43 and 63 are symmetrically arranged according to the rotating shaft 27. The first locking tongue 42 and the second locking tongue 62 are far apart from each other.
[0038] When the drive member 30 is rotated away from the bottle cap 20, the end of the drive member 30 located inside the bottle cap 20 pushes the first body 41 to slide towards the rotating shaft 27 and compresses the spring. The first locking tongue 42 disengages from the first locking hole 11 and retracts towards the channel 25. The first body 41 pushes the transmission member 50 to rotate, and the transmission member 50 pulls the second locking member 60 to slide towards the rotating shaft 27, bringing the first body 41 closer to the second body 61. The second locking tongue 62 disengages from the second locking hole 12 and retracts towards the channel 25. After the first locking tongue 42 and the second locking tongue 62 are completely disengaged from the first locking hole 11 and the second locking tongue 62 are completely disengaged from the second locking hole 12, the bottle cap 20 can then detach upwards from the bottle body 10. After the filter element is replaced, the bottle cap 20 is placed downwards on the upper end of the bottle body 10. The drive component 30 is released, and the first body 41 is pushed by the restoring force of the spring. The first locking component 40 slides towards the first locking hole 11, and the transmission component 50 rotates in the opposite direction. The first locking component 40 pushes the second locking component 60 towards the second locking hole 12 through the rotation of the transmission component 50, until the first locking tongue 42 is inserted into the first locking hole 11 and the second locking tongue 62 is inserted into the second locking hole 12. This completes the assembly of the bottle cap 20 and the bottle body 10. No special tools or professional personnel are required for replacement, which reduces costs and improves the user experience.
[0039] This utility model also provides a water purifier having at least one of the above-mentioned filter bottles 100 for easy filter replacement, so that users can easily replace the filter themselves.
