A hollow filter element 2 is arranged in the inner cavity 10, a water outlet cavity 3 is arranged above the shell 1, a water outlet 31 is arranged in the water outlet cavity 3, and a hollow cavity 30 of the filter element 2 is communicated with the water outlet cavity 3 through a water outlet air supply pipe 4. The lower part of the shell 1 is provided with a water inlet cavity 5, the water inlet cavity 5 is provided with a water inlet 51 and a sewage draining exit 52, the outer cavity 20 is communicated with a water inlet passage 53, and the water inlet cavity 5, the sewage draining exit 52 and the water inlet passage 53 are communicated through a water inlet and draining three-way valve 61. The flushing channel 54 is communicated between the water inlet cavity 5 and the inner cavity 10, a flushing valve 62 is arranged at the flushing channel 54, the flushing valve 62 is in a normally closed state, and the opening of the flushing valve is controlled by a flushing button 63. In addition, a drainage channel 55 is arranged between the bottom of the inner cavity 10 and the water inlet channel 53, and a check valve 56 is arranged at the drainage channel 55. Wherein, the flushing channel 54 is close to the water inlet 51, the water inlet channel 53 is close to the sewage draining exit 52, and the check valve 56 is communicated with the water inlet channel 53 from the inner cavity 10 in a one-way. The water inlet and outlet three-way valve 61 is respectively connected with the water inlet cavity 5, the water inlet channel 53 and the sewage outlet 52, and can be communicated with the water inlet cavity 5 and the water inlet channel 53 or the water inlet channel 53 and the sewage outlet 52. The upper part of the inner cavity 10 is communicated with the external space through the one-way ball float valve 7, the channel between the inner cavity 10 and the external space is closed when the first floating ball 71 of the one-way ball float valve 7 moves upwards, the channel between the inner cavity 10 and the external space is opened when the first floating ball moves downwards, the upper part of the outer cavity 20 is communicated with the external space through the air inlet one-way valve 9, and the air inlet one-way valve 9 is communicated with the outer cavity 20 in a one-way mode from the external space. The water outlet cavity 3, the outer cavity 20 and the inner cavity 10 are communicated through the bidirectional ball float valve 8, when a second ball float 81 of the bidirectional ball float valve 8 moves upwards, the passage of the outer cavity 20 and the water outlet cavity 3 is closed, the passage of the outer cavity 20 and the inner cavity 10 is opened, when the ball float moves downwards, the passage of the outer cavity 20 and the inner cavity 10 is closed, and the passage of the outer cavity 20 and the water outlet cavity 3 is opened.
When the water purifier is filled with water, the flush valve 62 is normally closed, the water inlet 51 communicates with the water inlet chamber 5, and the water inlet and outlet three-way valve 61 is operated to communicate the water inlet passage 53 with the water inlet chamber 5. At this time, the first ball 71 of the one-way ball float valve 7 is located below, the inner chamber 10 is communicated with the external space, the second ball 81 of the two-way ball float valve 8 is located below, the passage between the outer chamber 20 and the inner chamber 10 is closed, and the outer chamber 20 is communicated with the water outlet chamber 3. The external water outlet valve is closed, the external water inlet valve is opened, a pressure water source enters the water inlet cavity 5 from the water inlet 51, enters the outer cavity 20 through the water inlet channel 53, after the water overflows the small hole 21 below the inner shell 11, the water enters the inner cavity 10 from the outer cavity 20 through the small hole 21, at the moment, the air in the outer cavity 20 cannot be discharged from the inner cavity 10, the air pressure in the outer cavity 20 is increased, the air inlet one-way valve 9 is in a closed state, the air in the outer cavity 20 enters the water outlet cavity 3 through the two-way ball float valve 8, then enters the hollow cavity 30 of the filter element 2 through the water outlet air supply pipe 4, and is blown out of the filter element 2 through capillary micropores on the filter element 2, instant moving bubbles are formed in the hollow cavity 30, the bubbles are discharged to the outer wall of the filter element 2, dirt in the filter element 2 is promoted to be discharged, and dirt attached to the. Thereafter, the air in the outer chamber 20 continuously flows from the water outlet chamber 3 to the hollow cavity 30 of the filter element 2 and is blown out, and the dirt in the filter element 2 is continuously discharged in the process. The air blown from the filter element 2 is discharged to the outside space through the one-way ball float valve 7 above the inner chamber 10. Because the small hole 21 at the lower part of the inner shell 11 is far smaller than the cross section of the water inlet channel 53, and the damping effect of the water flowing through the small hole 21, the amount of water flowing from the outer cavity 20 to the inner cavity 10 through the small hole 21 is far smaller than the amount of water flowing into the outer cavity 20, the liquid level of the outer cavity 20 rises rapidly, and the pressure of the air flowing to the hollow cavity 30 of the filter element 2 is equal to the pressure of the water flowing in under the action of the pressure of the water flowing in. When the liquid level of the outer cavity 20 rises to the position of the second floating ball 81 of the bidirectional floating ball valve 8, the second floating ball 81 is pushed to move upwards, so that the passages of the inner cavity 10 and the outer cavity 20 are opened. Thereafter, the water in the outer chamber 20 flows to the inner chamber 10 through the passage, and finally, the liquid level in the inner chamber 10 reaches the position of the first float ball 71 of the one-way ball float valve 7, so that the first float ball 71 moves upward to close the passage between the inner chamber 10 and the external space. With the last water intake, the first float ball 71 of the one-way float valve 7 and the second float ball 81 of the two-way float valve 8 reach their ascending limit positions, the one-way float valve 7 completely seals the inner cavity 10 from the external space, and the two-way float valve 8 completely seals the outer cavity 20 from the water outlet cavity 3. Therefore, the whole water purifier water injection and filter element back flushing self-cleaning process is completed.
At this time, the external outlet valve is opened, and water flows from the outside of the filter element 2 into the hollow cavity 30 in the filter element 2 through the capillary pores on the filter element 2, then flows into the outlet cavity 3 through the outlet air supply pipe 4, and flows to the outside through the outlet 31. Normal filtration operation is started.
When the filter element needs to be subjected to back flushing self-cleaning for the next time, the water in the water purifier cavity needs to be discharged firstly. At this time, the external outlet valve is closed, and the inlet/outlet three-way valve 61 is operated to communicate the inlet passage 53 with the sewage drain port 52. The water in the outer cavity 20 flows out of the sewage draining port 52 through the water inlet passage 53, the water in the inner cavity 10 also flows into the outer cavity 20 through the small hole 21, the air inlet one-way valve 9 at the upper part of the outer cavity 20 is opened along with the falling of the liquid level, the air enters the upper part of the outer cavity 20 through the air inlet one-way valve 9, meanwhile, the first floating ball 71 of the one-way ball float valve 7 at the upper part of the inner cavity 10 falls, the upper part of the inner cavity 10 is communicated with the external space, and the air enters the upper part of the inner cavity 10. When the water in the cavity is emptied, the water inlet back flushing process of the next round can be started.
As the water flows from the inner chamber 10 to the outer chamber 20 through the apertures 21, dirt in the inner chamber 10 is also carried to the outer chamber 20 and is flushed from the waste outlet 52. However, the aperture of the small hole 21 is small, and the water flow which naturally falls back is slow, so that the dirt is not completely carried away. When the small hole 21 is far from the water inlet passage 53 or the position of the small hole 21 is slightly higher, the dirt is likely to be carried away by a small amount. If the flush valve 62 is initially opened after operation of the inlet and outlet valve 61, water under pressure will enter the inner chamber 10 through the flush passage 54, so that the flow of water from the orifice 21 to the outer chamber 20 will increase and carry more dirt away. In addition, due to the existence of the trapway 55, when a water source with water pressure enters the inner chamber 10, the water pressure in the inner chamber 10 will be greater than the water pressure in the outer chamber 20, the check valve 56 in the trapway 55 will preferentially open, and therefore, waste accumulated at the bottom of the inner chamber 10 will preferentially drain from the trapway 55 through the waste outlet 52.
The utility model discloses in, in order to increase the filtering quality of filter core 2, filter core 2 set to the ripples leaf form. The filter element is arranged in a wave-leaf shape, so that the area is increased by three times compared with a cylinder type, the water yield is increased by three times, the blocking resistance is also increased by three times, the times of cleaning and flushing are reduced by three times, and the flushing water is saved by three times. Because the utility model discloses utilize the air blowback, there is not the problem that ripples form filter core gap washs the difficulty.
