[0023] 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 of 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.

[0024] The following is combined with Figure 1-6 This application is described in further detail.

[0025] A straight filter comprises a base 2, a cylinder 4, a water inlet pipe 3, a water outlet pipe 1 and a first filter element 6 of the straight filter, wherein the cylinder 4 is detachably arranged on the base 2, a water inlet hole 9 is provided on the base 2, and the water inlet pipe 3 is fixedly connected to the water inlet hole 9. A water outlet hole 8 is provided on the base 2, and the water outlet pipe 1 is fixedly connected to the water outlet hole 8.

[0026] The water outlet 8 is threadedly connected with a fixing pipe 10, the fixing pipe 10 is between the cylinder 4 and the base 2, and the first filter element 6 is sleeved on the fixing pipe 10. The end of the first filter element 6 close to the water outlet 8 is fixedly connected with a connecting ring 13, and the end of the fixing pipe 10 close to the water outlet 8 is fixedly connected with a threaded ring 15, the threaded ring 15 is integrally formed with the fixing pipe 10, the connecting ring 13 is threadedly connected to the threaded ring 15, and the first filter element 6 is fixed to the fixing pipe 10.

[0027] A sealing ring 16 is sleeved on the threaded ring 15. When the threaded connection ring 13 is tightened, one side of the sealing ring 16 presses against the cylinder body 4, and the other side of the sealing ring 16 presses against the connection ring 13. The sealing ring 16 can ensure the sealing between the first filter element 6 and the fixed tube 10, so that unfiltered water cannot enter the water outlet 8 from the connection between the first filter element 6 and the fixed tube 10.

[0028] A limiting ring 14 is fixedly provided on one side of the fixed tube 10 close to the water outlet 8. The fixed tube 10 is plugged with a second filter element 7. The second filter element 7 is pressed against the limiting ring 14. The limiting ring 14 is between the second filter element 7 and the water outlet 8. The limiting ring 14 serves to limit the positioning of the second filter element 7.

[0029] When the water to be filtered enters the cylinder 4 from the water inlet pipe 3, the water enters the fixed pipe 10 after being filtered by the first filter element 6, and then enters the water outlet pipe 1 after being filtered for the second time under the action of the second filter element 7. At this time, the water coming out of the water outlet pipe 1 is relatively clean.

[0030] The second filter element 7 uses a HEPA filter element with a filtration grade of H14. The single filtration effect of this grade of filter element is 99.997%, which can better filter impurities in the water. The fixed pipe 10 is a pipe with multiple grids. The grids on the fixed pipe 10 facilitate the water filtered by the first filter element 6 to enter the second filter element 7 through the fixed pipe 10 for filtration.

[0031] A filter screen is fixedly arranged on the fixed pipe 10, and the filter screen plays a role in further enhancing the filtering effect, so that the filtering effect of the filter is better. A fixed cover 11 is arranged on the side of the fixed pipe 10 away from the water outlet 8, and the fixed cover 11 is threadedly connected to the fixed pipe 10. A spring 5 is fixedly arranged on the side of the fixed cover 11 close to the fixed pipe 10, and a fixed plate 12 is fixedly arranged on the side of the second filter element 7 close to the fixed cover 11, and the spring 5 is pressed against the fixed plate 12, and the spring 5 plays a role of buffering and positioning.

[0032] The implementation principle of this embodiment is: when using the filter for filtering, the water to be filtered enters the cylinder 4 from the water inlet pipe 3, and enters the fixed pipe 10 after the first filtration by the first filter element 6. When entering the fixed pipe 10, the water will pass through the filter screen on the fixed pipe 10 for the second filtration before entering the fixed pipe 10, and then pass through the second filter element 7 for the third filtration before flowing out of the cylinder 4 from the water outlet pipe 1. At this time, after the water has been filtered three times by the first filter element 6, the filter screen and the second filter element 7, the impurities in the water are basically filtered out, and the filtering effect is better, thereby achieving the effect of improving the filtering effect of the straight filter.
