Detailed Description

The invention is further described in the following with reference to fig. 1 to 4 in a specific embodiment:

a household filtering water nozzle comprises a body 1, a valve rod 2, a valve core 3 and a handle 4, wherein a water inlet 5 and a water outlet 6 are arranged in the body 1, a connecting part 7 is fixedly arranged at one end of the water inlet 5 on the body 1, an external thread is arranged on the outer surface of the connecting part 7, a plurality of filtering pieces 8 are fixedly arranged between the connecting part 7 and the body 1, each filtering piece 8 comprises a shell 80 and a filtering core 81, a protruding part 82 extends from one end of the shell 80, a plurality of clamping blocks 83 are fixedly arranged on the protruding part 82 and at one end far away from the shell 80, a sliding groove 84 matched with the clamping blocks 83 is arranged at the other end of the shell 80, each sliding groove 84 comprises a guide groove 84a and a clamping groove 84b, a plurality of round holes 85 are fixedly arranged at one end of the filtering core 81, clamping pieces 86 are fixedly arranged in the round holes 85, and a filtering net 87 is fixedly arranged at the other end of the filtering core 81, be equipped with on the inner wall of shell 80 with the corresponding card hole 9 of chucking spare 86, the body 1 is close to the one end of filtering piece 8 and is equipped with spout 84, connecting portion 7 is close to the one end of filtering piece 8 and is equipped with bellying 82, connecting portion 7, a plurality of filter piece 8 and body 1 all are equipped with sealing washer 10 between adjacent.

It can be seen from the above structure that the filtering element 8 is arranged at the front end of the water inlet 5 of the body 1 to prevent impurities from being accumulated in the body 1, which causes inconvenience in later cleaning, and meanwhile, the clamping block 83 is adopted to slide in through the guide groove 84a and then to be clamped and installed with the clamping groove 84b, the whole process does not need to use other tools, which is very convenient and fast, the difficulty of maintenance is greatly reduced, and the maintenance efficiency is improved, while the filtering element 81 is fixed by the matching of the clamping element 86 and the clamping hole 9, during installation, the filtering element 81 is placed in the shell 80, so that the clamping element 86 is clamped into the clamping hole 9 to complete installation, meanwhile, the protruding part 82 on the adjacent filtering element 8 can have an abutting and fixing effect on the filtering element 81, and when a plurality of filtering elements 81 are required to be installed to improve the filtering effect, only the shell 80 needs to be continuously installed backwards, meanwhile, various filter cores 81 can be used for people with different requirements.

As an alternative embodiment, the fastening member 86 includes a chuck 86a, a pull rod 86b and a spring 86c, the pull rod 86b penetrates through the bottom surface of the circular hole 85 and extends into the filter element 81, one end of the pull rod 86b close to the fastening hole 9 is fixedly connected with the chuck 86a, the other end is fixedly provided with a pull ring 86d, the spring 86c is sleeved on the surface of the pull rod 86b, one end of the spring 86c is fixedly connected with the chuck 86a, and the other end is fixedly connected with the bottom surface of the circular hole 85.

It can be seen from above-mentioned structure that, when installing and dismantling filter core 81, only need stimulate pull ring 86d, pull ring 86d drives pull rod 86b and makes dop 86a retract round hole 85 in, when round hole 85 aligns with card hole 9, loosen pull ring 86d, can go into card hole 9 with dop 86a card through spring 86c in, accomplish the installation, dismantle the same reason, it is very convenient, simple structure, easy realization.

As an alternative embodiment, the sealing ring 10 includes a first leather ring 10a and a second leather ring 10b, the first leather ring 10a and the second leather ring 10b are fixedly connected and form an annular groove 10c therebetween, and an elastic metal ring 10d is disposed in the annular groove 10 c.

It can be seen from the above structure that the sealing rings 10 are arranged between the connecting part 7, the plurality of filtering parts 8 and the body 1 to improve the sealing performance of the connecting part, and meanwhile, considering that the sealing rings 10 will expand and deform outwards when being stressed, and become irregular round for a long time, the axes will deviate, and the sealing performance will not be good when the sealing rings 10 are compressed again after being loosened, but the sealing rings 10 of the present invention are frequently replaced, so the annular grooves 10c on the sealing rings 10 are adopted, and the elastic metal rings 10d are embedded in the annular grooves 10c as the supporting framework, so that the sealing rings 10 are not easy to deform when being used for a long time, and the axes deviate to influence the sealing performance, and meanwhile, when the sealing rings 10 are aged, the elasticity is not good enough, the sealing performance is poor, and the sealing rings need to be replaced because the sealing rings are not bonded together, the elastic metal ring can be detached from the sealing ring 10, and only the rubber part needs to be replaced, so that the cost can be saved.

As an optional implementation manner, a fastening cylinder 11 is arranged between the body 1 and the valve rod 2, a plurality of rubber rings 12 are arranged between the fastening cylinder 11 and the valve rod 2, the bottom end of the valve rod 2 is fixedly connected with the valve core 3, and the top end of the valve rod is fixedly connected with the handle 4.

It can be seen from the above structure that the valve rod 2 is fixedly installed through the fastening barrel 11, and the sealing effect between the valve rod and the valve rod is improved by arranging the plurality of rubber rings 12 between the valve rod and the valve rod, so that water is prevented from leaking from a gap.

As an optional embodiment, a sealing ring 13 is fixedly arranged below the valve core 3, and a snap ring 14 is fixedly arranged on the inner wall surface of the sealing ring 13.

It can be seen from the above structure that the sealing performance inside the water nozzle is improved by the sealing ring 13, and the snap ring 14 plays a role in fixing the sealing ring 13.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
