Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

The first embodiment is as follows: as shown in fig. 1 and 2, which are only one of the embodiments of the present invention, the present invention provides an external fine mesh filter screen capable of being repeatedly cleaned and separated, including an inner cylinder 1 and an outer cylinder 2, wherein at least a portion of the inner cylinder 1 is arc-shaped, a side wall of the inner cylinder 1 is provided with a filter hole 11, the outer cylinder 2 is a sleeve, at least a portion of the inner cylinder 1 is located in the outer cylinder 2, the outer cylinder 2 is provided with a filter screen, the outer side of the outer cylinder 2 is provided with a fixing ring 21, and an inner diameter of the fixing ring 21 is not greater than an outer diameter of the.

The utility model discloses in, urceolus 2 cup joints in the 1 outside of inner tube, is provided with the filtration pore on the inner tube 1, is provided with the filter screen on the urceolus 2, and after the interior urceolus cup jointed, play the filterable effect to the water jointly. And adopt not welding between the interior urceolus, can freely take out from, in order to guarantee the stability of connecting between the interior urceolus, add on the urceolus 2 outside and establish a solid fixed ring 21, compress tightly the urceolus 2 and only laminate in the inner tube 1 outside, prevent that urceolus 2 from being torn the damage.

Here, the fixing ring 21 is made of steel, and is actually a steel hoop, the fixing ring 21 made of steel is sleeved outside the outer cylinder 2, the inner diameter of the fixing ring 21 is not larger than the outer diameter of the outer cylinder 2, and the fixing ring 21 made of steel has good toughness, high yield strength and good elasticity, so that the outer cylinder 2 is tightly tightened and attached outside the inner cylinder 1.

And the fixing ring 21 is arranged at the end of the outer cylinder 2, then the number of the fixing ring 21 is at least one, generally speaking, two ends of the outer cylinder 2 are both provided with a fixing ring 21, and if the length of the outer cylinder 2 is longer, then the middle of the outer cylinder 2 can also be provided with a fixing ring 21; even when a plurality of outer cylinders 2 are connected, the joint of the two outer cylinders 2 is also provided with a fixing ring 21, so that the stability of the outer cylinders 2 is ensured, and the outer filter screens of the outer cylinders 2 are more closely fixed on the inner screen of the inner cylinder 1.

It should be noted that the steps of mounting the inner and outer cylinders are as follows:

s1: sleeving the outer cylinder 2 to the outer side of the inner cylinder 1;

s2: a fixing ring 21 is fitted on the outer side of the outer cylinder 2.

The utility model relates to a can repeatedly wash and take out external fine mesh filter screen of formula simple structure, the interior urceolus can freely be taken out from, and takes out from simple, need not to cut out, circulated use, stability is high, long service life moreover.

Embodiment two, as shown in fig. 1 to 3, only do the utility model discloses a one of them embodiment, in order to make the utility model relates to a can repeat the washing and take out the lift effect of external fine mesh filter screen of formula better, the stability is higher, the utility model discloses in still have following design:

firstly, the outer side of the inner cylinder 1 is provided with a limiting hole 12, the outer cylinder 2 is provided with a limiting column 22 extending towards the direction of the inner cylinder 1, and the end part of the limiting column 22 far away from the inner cylinder 1 is connected with the fixing ring 21. The limiting column 22 penetrates through the outer cylinder 2, and is inserted into the limiting hole 12 of the inner cylinder 1 from the outer side of the outer cylinder 2, the limiting column 22 is pressed by the fixing ring 21, the limiting column 22 is not loosened in a movable mode, and stable connection of the outer cylinder 2 and the inner cylinder 1 is guaranteed.

Furthermore, the number of the limiting holes 12 and the limiting columns 22 is at least one. The multiple sets of limiting holes 12 are connected with the limiting columns 22, so that the limiting effect on the outer cylinder 2 is better.

Still, be provided with backup pad 13 in the inner tube 1, just filter screen on the urceolus 2 is for weaving the filter screen, and 1 stability height in inner tube, 2 filterability in urceolus are good, but self stability is relatively poor, so more need guarantee the laminating of urceolus 2 in the 1 outside of inner tube, guarantee the stability of urceolus 2, difficult tearing.

It should be noted that the installation steps of the inner cylinder 1 and the outer cylinder 2 additionally provided with the limiting hole 12 and the limiting column 22 are as follows:

s1: sleeving the outer cylinder 2 to the outer side of the inner cylinder 1;

s2: a limiting post 22 is arranged on the outer cylinder 2, and the outer cylinder 2 is moved, so that the inner end part of the limiting post 22 extends into the limiting hole 12;

s3: the outer side of the outer cylinder 2 is sleeved with a fixing ring 21, and the inner side of the fixing ring 21 presses the outer end of the limit column 22.

Here, if the inner and outer cylinders need to be drawn out, the inner and outer cylinders can be freely drawn out by first removing the fixing ring 21 and then removing the stopper posts 22.

The present invention is not limited to the above-described specific embodiments, and various modifications and changes are possible. Any modification, equivalent replacement, improvement and the like made to the above embodiments according to the technical spirit of the present invention should be included in the scope of protection of the present invention.
