However, the existing method of directly adding activated carbon requires packaging operations on both sides, which has low packaging efficiency and is not conducive to the rapid addition of activated carbon particles. Utility Model Content

DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The present application discloses a sintered carbon rod filter element that is convenient for adding activated carbon particles. Figure 1 、 Figure 2 as well as Figure 3A sintered carbon rod filter element that facilitates the addition of activated carbon particles includes a sintered carbon rod 1 and a connecting ring barrel 2 that is detachably connected to the sintered carbon rod 1. A cavity for placing the activated carbon particles is defined within the connecting ring barrel 2. A sealing cap 3 is also connected to the end of the connecting ring barrel 2 to seal and block the cavity. The user can also remove the connecting ring barrel 2 from the sintered carbon rod 1, then pull the sealing cap 3 off the connecting ring barrel 2, insert the activated carbon particles into the connecting ring barrel 2, and then plug the connecting ring barrel 2 with the sealing cap 3.

[0019] Reference Figure 1 、 Figure 2 as well as Figure 3 A sliding cavity 4 and a passing cavity 5 are provided in the sealing cover 3. The sliding cavity 4 is a straight cavity, and a control column 6 is connected to the sliding cavity 4. The control column 6 can slide along the opening direction of the sliding cavity 4; the opening direction of the sliding cavity 4 is perpendicular to the passing cavity 5. The sliding cavity 4 is opened at the bottom of the passing cavity 5 and is connected to the passing cavity 5. Reset blocks 7 are also slidably connected to the cavity openings on both sides of the sliding cavity 4. Reset springs 8 are also connected to the ends of the two reset blocks 7 that are close to each other. The two ends of the reset spring 8 are fixedly connected to the two ends of the reset block 7 respectively. The free ends of the two reset blocks 7 can also pass through the passing cavity 5 and align with the outer wall of the sealing cover 3.

[0020] Reference Figure 1 、 Figure 2 as well as Figure 3 The connecting ring tube 2 is also slidably connected with the same number of limit blocks 9 as the reset block 7. The position of the limit block 9 is set corresponding to the position of the reset block 7. The end of the limit block 9 facing the reset block 7 can be inserted into the passage cavity 5.

[0021] After the user inserts the sealing cover 3 into the connecting ring tube 2, in order to fix the sealing cover 3 and the connecting ring tube 2, it is only necessary to move the limit block 9 toward the reset block 7, insert part of the limit block 9 into the through cavity 5, and relatively fix the sealing cover 3 and the connecting ring tube 2 through the limit block 9.

[0022] If the user needs to remove the sealing cover 3 and the connecting ring tube 2 and insert the activated carbon granules into the connecting ring tube 2, the user needs to press the control column 6 to move the control column 6 toward the reset block 7. Since the reset block 7 has a chamfer 12 on one end facing the reset spring 8, when the control column 6 moves toward the reset block 7, the control column 6 will first contact the chamfer 12 and move the two reset blocks 7 away from each other through the squeezing of the control column 6. At this time, the reset spring 8 is in a stretched state. The original limit block 9 slowly escapes from the passage cavity 5 under the action of the reset block 7 until the limit block 9 is completely detached from the passage cavity 5. At this time, the sealing cover 3 and the connecting ring tube 2 can be separated without being restricted by the limit block 9.

[0023] When the control rod does not stretch the reset spring 8, the end of the control rod is in contact with the reset block 7, but the other end of the control rod is flush with the cover of the sealing cover 3. This design makes the control rod less likely to be disturbed by the outside world, thereby causing accidental touch.

[0024] Reference Figure 1 、 Figure 2 as well as Figure 3 A limiting groove 10 is also formed within the connecting ring tube 2 for the limiting block 9 to slide in. A rubber layer 11 is bonded to the inner wall of the limiting groove 10 to increase the friction between the limiting block 9 and the limiting groove 10. When the user pushes the control column 6, they can clearly feel the resistance caused by the friction between the limiting block 9 and the rubber layer 11. This resistance also prevents the limiting block 9 from moving too quickly, allowing the limiting block 9 to move stably within the limiting groove 10.

[0025] Reference Figure 1 、 Figure 2 as well as Figure 3 An expansion cavity 13 is also provided on the outer wall of the connecting ring tube 2. An adjustment ring 14 is slidably connected to the expansion cavity 13, and the notch of the limiting groove 10 is also located exactly in the expansion cavity 13. Magnetic parts 15 are fixedly connected to the inner cavity walls at both ends of the expansion cavity 13. The magnetic parts 15 are magnetically connected to the adjustment ring 14. When the adjustment ring 14 slides in the expansion cavity 13 and contacts the limiting block 9, the limiting block 9 will remain inserted into the passage cavity 5 under the restriction of the adjustment ring 14, and will not be pushed by the reset block 7 as the control column 6 slides.

[0026] When the adjusting ring 14 is misaligned with the limiting block 9 , the limiting block 9 will be pushed out of the passage cavity 5 by the reset block 7 under the action of the control column 6 because there is no restriction on the limiting block 9 by the adjusting ring 14 .

[0027] The adjustment ring 14 is adsorbed by the magnetic members 15 located on both sides of the expansion cavity 13. When the adjustment ring 14 is adsorbed by the magnetic member 15 on the side of the expansion cavity 13 close to the through cavity 5, the magnetic member 15 can lock the position of the adjustment ring 14 at this time, so that the adjustment ring 14 will not move at will. When the adjustment ring 14 is adsorbed by the magnetic member 15 on the side away from the through cavity 5, the adjustment ring 14 is misaligned with the through cavity 5, and when the user moves the control column 6, the position of the limit block 9 can be changed. The position of the adjustment ring 14 is locked by the magnetic members 15 located in different positions to achieve different effects.

[0028] Reference Figure 1 、 Figure 2 as well as Figure 3A positioning block 16 is integrally formed on the end of the sealing cover 3 facing the connecting ring barrel 2. Multiple positioning blocks 16 may be provided, but all positioning blocks 16 are offset from the passage lumen 5. A positioning cavity 17 is also defined within the connecting ring barrel 2 for the positioning blocks 16 to slide into. Once the user aligns the positioning blocks 16 with the cavity 17 and inserts the sealing cover 3 into the connecting ring barrel 2, the stop block 9 automatically aligns with the passage lumen 5.

[0029] The embodiment of the present application discloses a sintered carbon rod filter element that is convenient for adding activated carbon particles. The implementation principle is as follows: when filtering the sintered carbon rod 1, a large amount of activated carbon particles can be added to the connecting ring tube 2 inside the sintered carbon rod 1, thereby enhancing the adsorption effect. When performing this operation, the user only needs to open the sealing cover 3 and add the activated carbon particles into the connecting ring tube 2; and when the user needs to clean the activated carbon particles in the connecting ring tube 2, the user only needs to press the control column 6, and move the two reset blocks 7 away from each other through the control column 6, so that the limit block 9 can be moved out of the travel cavity 5 under the push of the reset block 7. At this time, the user can more conveniently remove the sealing cover 3 from the connecting ring tube 2, thereby realizing the filling of the activated carbon particles.

[0030] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
