DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Figure 1-5 As shown, the utility model provides a water purifier filter element locking structure, including a shell 1, the shell 1 includes a top plate 11, two filter element covers 12 and a base 13, the two filter element covers 12 are fixedly installed between the top plate 11 and the base 13, a filter element body 2 is slidably inserted in the two filter element covers 12, a locking assembly 3 is installed on the shell 1, two symmetrically distributed grooves 131 are opened in the base 13, and the grooves 131 are located in the corresponding filter element covers 12, and ejection assemblies 4 are installed in the two grooves 131. When the filter element body 2 is inserted, the filter element body 2 is pressed and inserted into the filter element cover 12, the filter element body 2 descends in the filter element cover 12 and squeezes the ejection assembly 4. When the filter element body 2 descends to the bottom end of the filter element cover 12, it can be fixed by using the locking assembly 3. When the filter element body 2 is taken out, the locking of the locking assembly 3 is released, and it is ejected by using the ejection assembly 4, so as to facilitate the removal of the filter element body 2.

[0021] The lock assembly 3 includes a turntable 33 , and the turntable 33 is rotatably mounted on the base 13 , and a connecting rod 32 is fixedly mounted on the turntable 33 .

[0022] By adopting the above technical solution, the connecting rod 32 drives the rotating disk 33 to rotate.

[0023] A knob 31 is rotatably mounted on the top plate 11 , and a lower surface of the knob 31 is fixedly connected to a top end of a connecting rod 32 .

[0024] By adopting the above technical solution, rotating the knob 31 drives the connecting rod 32 to rotate.

[0025] Two mirror-distributed locking plates 34 are slidably mounted on the base 13 and inserted into the corresponding filter element cover 12 . The bottom ends of the two filter element bodies 2 are each provided with a locking groove 21 , which is an annular groove, and the locking plates 34 can be slidably mounted into the corresponding locking groove 21 .

[0026] By adopting the above technical solution, the locking piece 34 is slidably inserted into the locking groove 21 at the bottom end of the filter element body 2 to lock and fix the filter element body 2.

[0027] Two connection plates 36 that are mirror-distributed are hingedly mounted on the upper surface of the rotating disk 33 , and the other ends of the connection plates 36 are hingedly connected to the corresponding locking plates 34 .

[0028] By adopting the above technical solution, the rotating disk 33 drives the locking piece 34 to slide through the connecting plate 36 .

[0029] Four telescopic spring rods 35 distributed in a mirror image are fixedly mounted on the upper surface of the base 13 , and one end of the telescopic spring rod 35 is fixedly connected to the corresponding locking piece 34 .

[0030] By adopting the above technical solution, the telescopic spring rod 35 can reset the locking piece 34.

[0031] The two ejection assemblies 4 each include a telescopic rod 41 , and the telescopic rod 41 is fixedly installed in the corresponding groove 131 , and a backing plate 43 is fixedly installed at the top of the two telescopic rods 41 , and the upper surface of the backing plate 43 contacts the bottom end of the filter element body 2 .

[0032] By adopting the above technical solution, when the filter element body 2 descends in the filter element cover 12 , the bottom end of the filter element body 2 contacts the backing plate 43 and squeezes the telescopic rod 41 .

[0033] The two telescopic rods 41 are both sleeved with a spring body 42 , and two ends of the spring body 42 are fixedly connected to the lower surface of the pad 43 and the bottom end of the groove 131 respectively.

[0034] By adopting the above technical solution, when the filter element body 2 descends in the filter element cover 12, the bottom end of the filter element body 2 contacts the pad 43 and squeezes the telescopic rod 41 and the spring body 42. When the filter element body 2 is taken out, the filter element body 2 can be ejected by utilizing the rebound force of the spring body 42.

[0035] Working principle: When the utility model is in use, when the filter element body 2 is inserted, the filter element body 2 is pressed and inserted into the filter element cover 12. When the filter element body 2 descends in the filter element cover 12, the bottom end of the filter element body 2 contacts the pad 43 and squeezes the telescopic rod 41 and the spring body 42. When the bottom end of the filter element body 2 contacts the locking piece 34, the bottom end of the filter element body 2 squeezes the locking piece 34 (the side where the locking piece 34 contacts the filter element body 2 is the bevel), so that the locking piece 34 retracts. When it reaches the position of the locking groove 21 on the filter element body 2, the resilience of the telescopic spring rod 35 is used to reset the locking piece 34 and snap it into the locking groove 21 of the filter element body 2, so as to lock and fix the filter element body 2.

[0036] When the filter element body 2 needs to be removed, the knob 31 is turned to drive the connecting rod 32 to rotate, and the connecting rod 32 drives the turntable 33 to rotate. The turntable 33 drives the locking plate 34 to slide through the connecting plate 36, so that the locking plate 34 is disengaged from the locking groove 21 of the filter element body 2. At this time, the filter element body 2 loses the locking of the locking plate 34 and is ejected by the rebound force of the spring body 42, which facilitates the removal of the filter element body 2.

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
