[0002] A water purifier is one of the most common household devices today. Its purpose is to filter tap water, remove impurities in the water, and achieve the effect of drinking water as soon as the tap is turned on. At the same time, clean drinking water is also beneficial to human health.

[0003] However, due to the differences in water sources in different places, even after the initial filtration by the water company, the hardness of the water still varies when it reaches the customer. The water hardness in some areas is higher, that is, the mineral content is higher. After boiling and evaporation of high-hardness water, a lot of scale is usually left.

[0004] As for water purifiers, these minerals can be intercepted by the water purifiers, but will be blocked in the filter, which will greatly shorten the life of the filter and require frequent replacement of the filter, which is very inconvenient for users in areas with high water hardness.

[0005] Therefore, how to solve the above problems is worth considering for those with ordinary knowledge in this field. Utility Model Content

[0018] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0019] See also Figure 1 , Figure 1The schematic diagram of the water filter device 10 of the present invention is shown. The water filter device of the present invention includes a first filter layer 11, a second filter layer 12 and a shell 13, wherein the shell 13 covers the first filter layer 11 and the second filter layer 12 to form a pipeline. The shell 13 also includes a water inlet 14 and a water outlet 15, so when water enters the water filter device 10, it will pass through the water inlet 14, the first filter layer 11, the second filter layer 12 and the water outlet 15 in sequence, that is, it will first be filtered by the first filter layer 11 and then filtered by the second filter layer 12. Among them, the water inlet 14 is connected to a tap water pipeline 5, and the water in the tap water pipeline 5 has been subjected to primary disinfection treatment upstream, and its bacterial content is significantly reduced compared with untreated natural water sources.

[0020] The first filter layer 11 includes a plurality of filter resin particles 11', which are ion exchange resins. When water flows through the filter resin particles 11', the magnesium ions and calcium ions in the water will exchange with the sodium ions of the filter resin particles 11', which means that the minerals (magnesium and calcium) in the water will be adsorbed by the filter resin particles 11', thereby reducing the minerals in the water, thereby achieving the effect of reducing the hardness of the water and softening it. The second filter layer 12 is an activated carbon layer, which can adsorb other impurities in the water, such as pesticides, trihalomethanes, odor molecules, chlorine and other substances.

[0021] Therefore, the minerals and other harmful substances in the water can be removed through the filtration of the first filter layer 11 and the second filter layer 12, and the water can be directly drinkable. In addition, the minerals in the water are reduced, and the life of the filter can be greatly increased. It can be applied to some areas with high water hardness. The actual implementation method will be described below.

[0022] See also Figure 2 and Figure 3 , Figure 2 The water filter device 100 of the present invention is shown. Figure 3The side cross-sectional view of the water filter device 100 is shown. The water filter device 100 includes a first filter layer 110, a second filter layer 120, a first housing 130 and a second housing 140. The first housing 130 is covered outside the first filter layer 110 and the second filter layer 120, and serves as the main housing of the water filter device 100. Further, the first housing 130 is a stainless steel shell, and includes a water inlet 131, a first water outlet 132, a first water outlet pipe 133, a body 134, a cover 135, a buckle 136, a gasket 137 and a first sealing sleeve 138. The gasket 137 is disposed between the body 134 and the cover 135, and the first sealing sleeve 138 is disposed on the gasket 137, so as to provide a sealing effect between the body 134 and the cover 135, so that the first housing 130 is sealed to serve as a water flow channel. In addition, the cover 135 , the gasket 137 and the body 134 are fixed via the buckle 136 . The buckle 136 also includes a quick-release structure to facilitate the quick separation of the cover 135 and the body 134 for easy replacement of the filter element.

[0023] The water inlet 131, the first water outlet 132 and the first water outlet pipe 133 are arranged on the cover body 135. Among them, the first water outlet 132 is arranged at the center of the cover body 135, and the water inlet 131 is arranged at a position close to the edge. The first water outlet pipe 133 is arranged on the inner side and connected to the first water outlet 132. The arrangement of the water inlet 131, the first water outlet 132 and the first water outlet pipe 133 is matched with the configuration of the first filter layer 110 and the second filter layer 120 to form a water flow channel.

[0024] The first filter layer 110 and the second filter layer 120 are both cylindrical, and the first filter layer 110 is arranged around the second filter layer 120, that is, the first filter layer 110 is sleeved on the second filter layer 120. Specifically, the first filter layer 110 is a mesh container made of non-woven fabric, and filter resin particles 111 are arranged inside, and these filter resin particles 111 are ion exchange resins. The second filter layer 120 is an activated carbon layer.

[0025] The second filter layer 120 is supported by a second housing 140, which includes a second water outlet pipe 141, a protrusion 142, a plurality of second water outlets 143 and a second cover 144. Figure 3 and Figure 4 , Figure 4The diagram shows a partial exploded view of the water filter device 100. The protrusion 142 is disposed above the second housing 140, and a second water outlet 143 and a second sleeve 144 are disposed on the protrusion 142. The second water outlet 143 is disposed through the protrusion 142, and the second sleeve 144 is closely matched with the first water outlet 132 to separate the water inlet and water outlet pipes. The second water outlet pipe 141 is disposed below the second housing 140, extending into the hollow portion 121 of the second filter layer 120, and the second water outlet pipe 141 is connected to the second water outlet 143. In one embodiment, the second housing 140 further includes a transparent housing 151 and at least one germicidal lamp 152, which is disposed in the second water outlet pipe 141, and the germicidal lamp 152 is disposed in the transparent housing 151, wherein the germicidal lamp 152 is, for example, an ultraviolet lamp. The path of the water flow will be described below.

[0026] Next, please refer to Figure 5 , Figure 5 The diagram shows a water flow path. First, water enters the first housing 130 through the water inlet 131. The water entering the first housing 130 passes through the first filter layer 110 from the side. The filter resin particles 111 in the first filter layer 110 exchange ions with the water, adsorbing magnesium and calcium ions in the water, thereby removing minerals from the water and reducing the hardness of the water.

[0027] After passing through the first filter layer 110, the water enters the second filter layer 120 and is filtered by the activated carbon layer of the second filter layer 120 to further absorb impurities in the water. In particular, due to the arrangement of the second water outlet pipe 141, the water passing through the second filter layer 120 will flow downward and enter the second water outlet pipe 141. In one embodiment, the water entering the second water outlet pipe 141 will be irradiated by the germicidal lamp 152 to further kill bacteria in the water, and the germicidal lamp 152 is arranged in the transparent housing 151, so it will not directly contact the water. It is worth noting that in many home and commercial environments, since drinking water is not used continuously, when the water flow is not active, the water can be exposed to the germicidal lamp 152 for a long time, and this long-term exposure enables the germicidal lamp 152 to effectively achieve a significant sterilization level. Then, when the water source is continuously supplied, the pressure causes the water to flow upward along the second water pipe through the second water outlet 143 into the first water outlet pipe 133, and then continue to move upward through the first water outlet pipe 133 and leave the water filtration device 100. The entire filtering process is thus completed, and the first water outlet pipe 133 can be connected to a drinking water valve for the user to use.

[0028] The water filter device 100 of the utility model allows water to use ion exchange resin particles before entering the activated carbon filter to remove magnesium ions and calcium ions in the water through ion exchange, reduce minerals in the water, and achieve the effect of softening the water quality. Subsequent filtration will not easily leave too much residue on the activated carbon or other filter cores, which can greatly increase the life of the filter core and allow the water filter device 100 to adapt to areas with hard water quality.

[0029] The above embodiments are merely examples for the convenience of explanation, and any modification by a person skilled in the art will not deviate from the scope of protection as claimed in the claims.
