That is, the filter medium 200 is disposed in the water containing chamber 101, the outer surface thereof corresponds to the raw water chamber 1011, the inner surface corresponds to the purified water chamber 1012, and water in the raw water chamber 1011 flows from the outer surface of the filter medium 200 to the inner surface of the filter medium 200 due to gravity to enter the purified water chamber 1012. Then, the cover 300 is sleeved on the water outlet channel 103, and covers the top of the water outlet channel 103, so that purified water is not directly dripped into the water outlet channel 103, but is stored in the purified water cavity 1012 to the top surface of the cover 300, at this time, the water in the purified water cavity 1012 flows into the water outlet channel 103 from the second water passing gap 105 through the first water passing gap 104 and flows out from the water outlet hole 102 due to the action of water pressure and air pressure, thus forming a siphon phenomenon, negative pressure is formed at the top of the water outlet channel 103, and the water flow in the purified water cavity 1012 is accelerated, so that the filtering speed of the filter material 200 is also improved; in addition, due to the action of water, air in the water purifying cavity 1012 can be completely removed, and the flow of the filtered water is not influenced by air resistance, so that the flow is stable.

Therefore, according to the filter element device 1 of the present invention, the water outlet channel 103 is provided in the water purifying chamber 1012, and the cover 300 is sleeved on the water outlet channel 103, so that the first water passing gap 104 and the second water passing gap 105 are formed between the cover 300 and the water outlet channel 103. Thus, the raw water enters the raw water cavity 1011 and is filtered by the filter material 200 under the action of gravity, and then enters the water purifying cavity 1012, and when the purified water in the water purifying cavity 1012 is stored to the top surface of the cover 300, the purified water can pass through the first water passing gap 104, the water outlet channel 103 and the water outlet hole 102 from the second water passing gap 105 in one way. So be favorable to gaseous whole discharge, solve the problem of filter medium 200 air blocking, first water clearance 104, second water clearance 105 and play water passage 103 also form siphon structure for water in the water purification chamber 1012 is drawn forth rapidly from play water passage 103 according to the siphon principle, thereby utilizes the combination of negative pressure and gravity to make the filtration rate of filter medium 200 promote, improves water velocity, and the flow of water purification does not have the influence of air lock, and the flow is stable, and play water is just stable yet.

When the filter medium 200 is in a sheet form, the raw water chamber 1011 is above the filter medium 200, and the purified water chamber 1012 is below the filter medium 200. When the filter medium 200 is in an inverted bowl shape or an inverted cylinder shape, the raw water chamber 1011 is outside the top outer surface and the outer peripheral surface of the filter medium, and the water purifying chamber 1012 is inside the inner surface of the filter medium 200.

That is, the filter medium 200 is supported by the support 400 provided around the outer circumference of the housing 300 such that the filter medium 200 may define the raw water chamber 1011 and the purified water chamber 1012 within the water containing chamber 101. The filter medium 200 may cover only the top surface of the support 400, or cover the top surface of the support 400 and cover the outer circumferential surface of the support 400. The raw water cavity 1011 and the water purifying cavity 1012 can be reasonably limited by the arrangement of the supporting piece 400, the space layout is facilitated, the raw water is filtered by the filtering material 200 flowing downwards from the top due to the gravity effect by the arrangement of the filtering material 200, the water purifying cavity 1012 defined by the cooperation of the filtering material 200 and the supporting piece 400 is in a negative pressure state when the purified water in the water purifying cavity 1012 is close to a full cavity, and the efficiency of filtering water by the filtering material 200 can be further improved by combining the negative pressure with the gravity.

Thus, when the filter medium 200 covers the outer circumferential surface of the supporter 400, water filtered by the filter medium 200 may also enter the water purifying chamber 1012 from the interval between the adjacent support plates.

Further, each support plate is disposed upright. That is, the top end of each support plate serves to support the filter 200, and the bottom end thereof may contact the bottom surface of the water containing chamber 101. In some specific examples, the bottom end of the support plate may be fixed to the bottom surface of the water containing cavity 101, simplifying the assembly of the cartridge device 1.

In some embodiments of the present invention, in conjunction with fig. 5 and 9, the support 400 may be a support cylinder that is disposed upright. Thus, the top end of the supporting cylinder supports the filter material, the bottom end of the supporting cylinder contacts the bottom surface of the water containing cavity 101, the periphery of the supporting cylinder is sealed, the condition that the water purifying cavity 1012 is closer to negative pressure can be met, and the sealed peripheral surface also enables the granular filter material to be placed in the water purifying cavity 1012.

The filter material 200 filters raw water, and the filter material performs bacteriostasis or softening on purified water, etc., so as to improve water quality.

Further, the granular filter material can be one or more of granular carbon, ion exchange resin, ceramic balls, alkaline balls, tourmaline, KDF and fossil.

The raw water enters the raw water cavity 1011 to have rectifying and guiding functions, so that the water flow is more stable, the aeration phenomenon is reduced, the phenomenon that the flow speed is suddenly reduced due to the fact that more air is mixed in the raw water and enters the filter material is avoided, and the filtering efficiency is further improved.

Optionally, a plurality of water inlet holes 701 are located on a peripheral wall of the cover 700 and arranged in an array, and a plurality of air outlet holes 702 are located on top of the cover 700. Thereby, the cover 700 has the functions of rectification and diversion, and the water flow is stable, so that the gas-water separation is realized to a certain extent.

Alternatively, the cover 700 is snap-connected to the housing 100, such that the cover 700 can be placed over the housing 100.

According to the filter equipment of the second aspect of the invention, through the arrangement of the filter element device 1, the filtering speed of the filter material is improved, the water flow speed is improved, and the water flow stability and the water outlet stability are ensured.
