[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0034] according to Figures 1 to 10 A locking and unlocking device for a filter bottle is disclosed. The filter bottle includes a bottle body 1 and a cap 2. The cap 2 is detachably fixed to the bottle opening at the top of the bottle body 1. A filter element 3 is located in the space between the bottle body 1 and the cap 2. The filter bottle is detachably fixed in the filter bottle cavity 32 of the body 31 of a suitable filter machine. The key improvement is that the cap 2 includes a base 4 and a handle 5. The base 4 includes a base 6 and a cover 7. The base 6 has a recessed mounting cavity with a central shaft 8. There is an unlocking groove 9 on each side of the central shaft 8. Each unlocking groove 9 has a locking tongue 10 with a push shaft 11. An elastic element 12 is fixed between the inner end of the locking tongue 10 and the unlocking groove 9 to keep it in an outward popping tendency. The corresponding base 6 has a base release mechanism. The lock hole 13; the center of the intermediate plate 14 has a through hole 15 for the central shaft 8 to pass through, and a transverse sliding groove 16 is provided on each side of the through hole 15 for the push shaft 11 on the lock tongue 10 to pass through and slide. The intermediate plate 14 is arranged on the mounting cavity of the base 6; the center of the cover 7 has a central hole 17, and the outer wall of the cover 7 has a cover unlocking hole 18 that matches the unlocking hole 13 of the base, allowing the lock tongue 10 to pass through when locked. The cover 7 is fitted onto the base 6 and connected together; the bottom center of the handle 5 has a central shaft hole 19 for the central shaft 8 to be inserted and connected. The bottom of the handle 5 has arc-shaped guide holes 20 for the push shaft 11 on the lock tongue 10 to pass through. By cooperating with the transverse sliding groove 16 of the intermediate plate 14, the lock tongue 10 is facilitated to slide inward and outward.
[0035] The inner wall of the unlocking groove 9 is provided with a limiting block 21, and the two sides of the corresponding locking tongue 10 are provided with limiting parts 22, which match each other to achieve limiting and fixing, prevent the locking tongue 10 from moving excessively, increase the life of the locking tongue 10 and prevent it from popping out. The inner end of the locking tongue 10 is provided with a spring fixing post 23, and the inner end of the unlocking groove 9 is provided with an elastic fixing seat 24. An elastic element 12 is fixed between the spring fixing post 23 and the elastic fixing seat 24, which always applies an outward pushing force to help the locking tongue 10 cooperate with the locking port of the body to lock. The elastic element 12 is preferably a spring.
[0036] The top of the intermediate plate 14 is also provided with two additional fixing shafts 25. The fixing shafts 25 pass through the arc-shaped guide holes 20, and cooperate with the handle 5 to make the rotation of the handle 5 more stable and easy. The top of the fixing shafts 25 and the push shaft 11 is fitted with limit rings 26 to prevent the fixing shafts 25 and the push shaft 11 from coming out of the arc-shaped guide holes 20. The intermediate plate 14 is provided with multiple fixing holes 27, preferably four. Screws pass through the fixing holes 27 and are fixed to the screw posts 28 on the top of the base 6, so that the intermediate plate 14 and the base 6 are fixed together, increasing the firmness.
[0037] Preferably, there are four arc-shaped guide holes 20 at the bottom of the handle 5. The radius of the arc-shaped guide holes 20 gradually changes along the inner side from the center of the handle, respectively matching the number of fixed shafts 25 and push shafts 11. Preferably, there are two fixed shafts 25 and two push shafts 11, arranged alternately, thereby realizing the connection and pushing function between the handle 5 and the base 4. The inner wall of the cover 7 is provided with a buckle 29, and correspondingly, the outer wall of the base is provided with a groove 30 to realize the snap-fit fixation.
[0038] When using this product, the user only needs to rotate the handle 5 on the top of the bottle body 1. During the rotation of the handle 5, the arc-shaped guide hole 20 drives the push shaft 11 to move along the transverse slide groove 16, thereby allowing the locking tongue 10 to move inward. The locking tongue 10 moves away from the fixed part on the machine body, such as the locking hole 33, passes through the base unlocking hole 13 and the cap unlocking hole 18, and then retracts into the unlocking groove 9. Then, the bottle body 1 is pulled out from the filter bottle cavity of the filter body by the handle 5. After replacing the new filter element 3, the bottle body 1 is pushed back into the filter bottle cavity. With the force applied by the elastic element 12, the locking tongue 10 passes through the base unlocking hole 13 and the cap unlocking hole 18 and is fixed to the fixed part on the machine body, such as the locking hole, thereby achieving the locking state.
