Filter cartridge device

The present invention relates to a filter cartridge device, and more particularly to a filter cartridge device that can be easily replaced with a filter cartridge and can be adjusted in the direction of the inlet and outlet with different placement positions.

Generally, most of the water is tap water. Although it is initially filtered by the water purification field, it still contains many harmful substances such as heavy metals and sediments that may endanger human health. Therefore, it is not suitable for direct drinking or use. To eliminate these harmful substances. Water filtration equipment is usually used to filter out these harmful substances to obtain cleaner water quality. In particular, in front of the water tower at home, a water filtration device will be added to allow all residents to use the same quality water.

The existing water filtering device, such as the new patent case No. M541891 of the Republic of China, discloses a filter device capable of taking into consideration the convenience of cleaning and replacing the filter material, which is mainly for sequentially filling a plurality of filter materials in a cylinder. Separate filter cartridges, and a filter screen is arranged on the top and bottom of each of the independent filter cartridges, so that the plurality of filter cartridges are used to form a multi-layer filter structure in the cylinder body to introduce a water source under the cylinder body.

The water source passing through the external filter unit 30 is filtered through the filter layer 43 and then flows into the water filter channel 41 through the through holes 42 to flow into the communication pipe 24, and finally flows into the water supply pipe. In the water collecting area 23 of the barrel 201, the water source entering the water collecting area 23 via the water inlet 25 can be filtered at least by secondary filtration, thereby achieving an effective filtering effect on the water source. In this embodiment, the built-in filter element unit 40 is an integrated design, and the filter layer 43 is a composite layer. Of course, the filter layer 43 can also be a single layer design; in other words, the filter layer 43 can be mainly based on Different kinds of filter materials are selected for use in different occasions, and the filter material can be combined with one of the filter materials such as activated carbon, bamboo carbon, nano silver and ceramics, and the filter layer 43 can be used for different occasions. The changes and combinations.

In addition, as shown in FIGS. 1, 4 and 5, the water inlet 25 of the present invention includes a first water inlet 251 and a second water inlet 252, and the water outlet 26 includes a first water outlet. 261 and the second water outlet 262, the first water inlet 251 and the second water inlet 252 are disposed in a direction perpendicular to each other, and the same between the first water outlet 261 and the second water outlet 262 is also The second water inlet 252 is located above the first water outlet 261, and the first water inlet 251 and the second water outlet 262 are opposite to each other. In this way, when the filter cartridge device 10 is actually installed, the water inlet 25 and the water outlet 26 can be selected to be used in different directions through different directions. For example, when the first water inlet 251 is selected to introduce the water source, the water source is closed. The second water inlet 252 is closed, and the first water inlet 251 is closed when the second water inlet 252 is selected to be introduced into the water source. Of course, the first water inlet 251 and the second water inlet 252 may be selected to be used at the same time. On the contrary, when the first water outlet 261 is selected to output the water source, the second water outlet 262 is closed, and when the second water outlet 262 is selected to output the water source, the first water outlet 261 is closed, and of course, the simultaneous use may be selected. The first water outlet 261 and the second water outlet 262. As shown in FIGS. 3 and 4, in the present embodiment, when the water source is selected to be introduced by the first water inlet 251, the water source sequentially passes through the external filter unit 30 and the built-in filter unit 40, and then passes through the The through holes 42 enter the water filtering channel 41, and the communication pipe 24 enters the water collecting area 23, and the water source is discharged from the first water outlet 261, thereby utilizing the first water inlet 251 and the The first water outlet 261 is vertically disposed, and the first water inlet 251 and the first water outlet 261 which are vertically disposed are also capable of being installed in a position close to the corner of the wall to avoid occupying a space. The water is caused to generate a reflux state in the filter cartridge device 10 to increase the filtering effect of the water source.
