As shown in fig. 1, the present embodiment discloses a pre-filter pressure control device. The pressure control device of the pre-filter of the embodiment has two states of a normal working state and a filter element cleaning state.

The pressure control device of the pre-filter of the present embodiment includes a bottle 50, and the bottle 50 is provided with a raw water inlet 51 and a purified water outlet 52. The bottle 50 has a filter element (not shown) therein. In a normal operation state, water entering the bottle 50 from the raw water inlet 51 is filtered by the filter element and then flows out from the purified water outlet 52 for a user to use.

In order to facilitate the sewage discharge, the bottle body 50 is further provided with a sewage discharge outlet 53 and a knob 54 for controlling the opening or closing of the sewage discharge outlet 53. When the filter element needs to be cleaned, water entering the bottle 50 from the raw water inlet 51 cleans the filter element, and after cleaning is completed, sewage is discharged through the sewage outlet 53. Then, the drain 53 is closed again, and the pre-filter pressure control device enters a normal working state.

The pre-filter pressure control device of the present embodiment further includes an inner support 10 and a rotating sleeve 20. The rotating sleeve 20 is rotatably mounted to the inner housing 10, and the inner cavity of the rotating sleeve 20 forms an inlet chamber. The inner frame 10 also has an inner cavity and a hollow structure. Both ends of the inner bracket 10 protrude outside the rotating sleeve 20. Three through holes 211 are opened at the peripheral wall of the rotating sleeve 20, and the three through holes 211 are uniformly distributed in the circumferential direction and are respectively arranged at the upper section, the middle section and the lower section of the rotating sleeve 20. The three through holes 211 are each inclined in a clockwise direction or an anticlockwise direction. The filter element is mounted on the inner bracket 10 and sleeved outside the rotating sleeve 20.

When the filter element is cleaned, water entering the raw water inlet 51 enters the inner cavity of the rotary sleeve 20, when the water flows out from the three through holes 211, the rotary sleeve 20 rotates under the action of water flow, and the water flowing out from the three through holes 211 is sprayed to the filter element in a rotating state, so that the cleaning effect on the filter element is improved.

As shown in fig. 5 and 6, in the present embodiment, the rotating sleeve 20 has a thickened portion 21, and a through hole 211 is provided in the thickened portion 21. The embodiment provides the thickened portion 21 to increase the extending length of the through hole 211, so that the inclination angle of the through hole 211 plays a better role, and the rotating sleeve 20 can rotate better when water flows out of the three through holes 211. Specifically, the rotating sleeve 20 has three thickened portions 21, and three through holes 211 are provided on the three thickened portions 21, respectively.

In this embodiment, two opposite sidewalls of the through hole 211 are curved surfaces. In other alternative embodiments, the two opposing sidewalls of the through-hole 211 are beveled.

As shown in fig. 6, in the present embodiment, an intersection point of the center line of the through hole 211 and the circle of the rotating sleeve 20 is defined as a reference point, and an included angle a between the radius of the circle of the rotating sleeve 20 passing through the reference point and the center line is an obtuse angle, and the obtuse angle is 110 ° to 170 °. For example, the obtuse angle is 110 °, 120 °, 130 °, 160 °, or 170 °. The rotating sleeve 20 rotates more smoothly at this moment, and the effect of water flow for cleaning the filter element is better.

In this embodiment, the thickness of the thickened portion 21 is 1.2 to 3 times the thickness of the rest of the rotating sleeve 20. For example, the thickness of the thickened portion 21 is 1.2 times, 2 times or 3 times the thickness of the rest of the rotating sleeve 20. The rotating sleeve 20 rotates more smoothly at this time, which is beneficial to improving the effect of cleaning the filter element.

As shown in fig. 2-4, the pressure control device of the pre-filter of the present embodiment further includes a filter core frame 30, the filter core frame 30 is sleeved outside the rotating sleeve 20 and is spaced from the rotating sleeve 20, and a filter core is installed on the filter core frame 30. The filter element frame 30 has a hollow structure for water to pass through. The filter element frame 30 is spaced from the rotary sleeve 20 by a distance, so that the filter element is spaced from the rotary sleeve 20 by a distance, water sprayed from the through holes 211 acts on the filter element with a certain action force, impurities attached to the outer surface of the filter element are washed from inside to outside, and the effect of cleaning the filter element is ensured.

The pre-filter pressure control device of the present embodiment further includes an outer bracket 40, the outer bracket 40 is installed in the inner cavity of the bottle body 50, and the inner bracket 10, the rotary sleeve 20 and the filter element are all installed in the inner cavity of the outer bracket 40.

The inner support 10 of the pressure control device of the pre-filter of the present embodiment is reciprocally movable by the siphon and the return spring to switch the water flow direction so that the water flow flows from the first water flow passage to the second water flow passage or from the second water flow passage to the first water flow passage. Specifically, in a state of cleaning the filter element, the drain outlet 53 is opened, and the main body end 11 of the inner bracket 10 moves downward by a certain distance under the siphon action to switch the water flow passage, so that the water entering from the raw water inlet 51 enters the inner cavity of the filter element at the top through the first water inlet 421, and then enters the inner cavity of the rotary sleeve 20, i.e., the inner cavity of the filter element. The sewage after the filter element is cleaned enters the second water flow channel and is finally discharged from the sewage discharge port 53.
