[0037] Traditional water filtration equipment, limited by a single filtering mechanism, can usually only remove some impurities in the water, but cannot efficiently mineralize the water quality. As living conditions continue to improve, people's requirements for water quality are also getting higher and higher, so mineralized filters are used. Mineralized filters are accessories that help water purification equipment decompose pure water and provide nutrients. The service life of traditional mineralized filters is short. After 3-5 months of continuous use, its mineralization efficiency drops significantly and cannot meet people's long-term use needs, resulting in frequent filter replacement cycles and an average annual maintenance cost of more than 700 yuan, which not only increases the economic burden of users, but also causes a waste of resources.

[0038] In view of this, the utility model provides a cascade mineralization device 100, which is used in a water purification device. Figure 1 and Figure 2 This is an embodiment of a cascade mineralization device 100 provided by the utility model.

[0039] See also Figure 1 and Figure 2The cascade mineralization device 100 includes a housing 1, a cascade mineralization component 2, and a switch component 3. The housing 1 is extended along a first direction, and one end of the housing 1 is provided with a water inlet 11 for introducing water to be mineralized, and the other end is provided with a water outlet 12 for conducting mineralized water. The housing 1 has a water-containing cavity 13 extending along the first direction. The water-containing cavity 13 includes a first cavity 131, a second cavity 132, and a third cavity 133 sequentially distributed along the first direction. The first cavity 131 is opposite to the third cavity 133. The body 133 is arranged near the water inlet 11; the cascade mineralization component 2 includes a first-stage filter element 21, a second-stage filter element 22 and a third-stage filter element 23, all of which contain mineralized balls. The particle size of the mineralized balls of the first-stage filter element 21, the particle size of the mineralized balls of the second-stage filter element 22 and the particle size of the mineralized balls of the third-stage filter element 23 increase in sequence. The first-stage filter element 21 is arranged in the first cavity 131 to divide the first cavity 131 into a first water passage cavity 1311 and a first water collection cavity 1312 along the inner and outer directions, and the first water passage cavity 13 The second-stage filter element 22 is arranged in the second cavity 132 to divide the second cavity 132 into a second water passage cavity 1321 and a second water collection cavity 1322 along the inner and outer directions; the third-stage filter element 23 is arranged in the third cavity 133 to divide the third cavity 133 into a third water passage cavity 1331 and a third water collection cavity 1332 along the inner and outer directions; the switch assembly 3 includes a first water collection switch 31, a second water collection switch 32, a first water collection switch 33, a second water collection switch 34 and a third water collection switch 35; The water collection switch 35, the first water collection chamber 1312 is connected to or disconnected from the second water flow chamber 1321 through the first water collection switch 31, and is connected to or disconnected from the water outlet 12 through the first water collection switch 33, the second water collection chamber 1322 is connected to or disconnected from the third water flow chamber 1331 through the second water collection switch 32, and is connected to or disconnected from the water outlet 12 through the second water collection switch 34, and the third water collection chamber 1332 is connected to or disconnected from the water outlet 12 through the third water collection switch 35.

[0040] In the technical scheme of the present utility model, the cascade mineralization device 100 includes a shell 1, a cascade mineralization component 2 and a switch component 3, the cascade mineralization component 2 includes a first-stage filter element 21, a second-stage filter element 22 and a third-stage filter element 23, all of which contain mineralized balls, and the connection state between the water collection chamber and the water outlet 12, as well as the connection state between the water passage chamber and the water passage chamber are controlled by the switch in the switch component 3; thus, during the use cycle of the cascade mineralization device 100, only the first water collection switch 33 can be opened first, and the first-stage filter element 21 can be used for mineralization. When the mineralization effect of the first-stage filter element 21 is poor due to its long use time, the first water collection switch 33 can be closed, the first water collection switch 31 and the second water collection switch 34 can be opened, and the second-stage filter element 22 can be used to enhance the mineralization effect. When the mineralization effect of the second-stage filter element 22 is poor due to its long use time, the second water collection switch 34 can be closed, the second water collection switch 32 and the third water collection switch can be opened. The water switch 35 adopts the third-stage filter element 23 to enhance the mineralization effect; thus, when the mineralization performance of the first-stage filter element decreases, the performance loss is compensated by opening or closing the corresponding switch, and the first-stage filter element 21, the second-stage filter element 22 and the third-stage filter element 23 are gradually adopted to work, so as to maintain the stability of the mineral release concentration; at the same time, the mineralized ball particle size of the first-stage filter element 21, the mineralized ball particle size of the second-stage filter element 22 and the mineralized ball particle size of the third-stage filter element 23 are increased successively, and the mineralized balls of different particle sizes are distributed in different water passage chambers. Because the mineralized balls with larger particle sizes have a smaller specific surface area than the mineralized balls with smaller particle sizes, the release rate of the minerals is slowed down, thereby controlling the release rate of the minerals when the water flows through each water passage chamber, and being able to achieve a more balanced and stable mineral concentration output as a whole, so as to achieve the effect of extending the service life of the cascade mineralization device 100, meet the user's use needs, and thus reduce the maintenance cost, reduce the user's economic burden and waste of resources.

[0042] Furthermore, the cascade mineralization device 100 further includes a monitoring component 4 and a controller.

The controller is electrically connected to the monitoring component 4 and each switch in the switch assembly 3 to control the working state of each switch in the switch assembly 3 according to the monitoring result of the monitoring component 4. In this way, the automatic monitoring of water quality parameters is realized through the monitoring component 4, and then the controller opens or closes each switch according to the monitoring result to control the water flow path, thereby controlling the working state of each filter element and realizing automatic cascade mineralization.

[0043] It should be noted that, in the present invention, the monitoring component 4 and the controller can be separately arranged or integrated. More specifically, in an embodiment of the present invention, the monitoring component 4 is a multi-parameter water quality measurement probe.

Figure 1 In one embodiment of the present invention, at least one first filter element 7 is disposed in each of the first cavity 131, the second cavity 132 and the third cavity 133. The first filter element 7 is disposed inside the filter element in each cavity, and a water passage cavity is formed inside the first filter element 7.

[0053] Specifically, the first filter element 7 is cylindrical and extends along the first direction. The first filter element 7 is made of activated carbon material. In this way, the water body is filtered and purified by the adsorption function of the activated carbon.

[0054] It should be noted that, in the present invention, the number of the first filter elements 7 is not limited, and may be one, two, three or more.

[0055] For details, please refer to Figure 1 In one embodiment of the present invention, two first filter elements 7 are provided, and the two first filter elements 7 are both extended along the first direction and are both cylindrical.

[0057] Specifically, the outer wall of each switch in the switch assembly 3 is provided with a closing sheet. Furthermore, the closing sheet is made of hot-melt adhesive material and is waterproof, thereby protecting the structure of each switch and preventing mechanical damage, chemical corrosion and erosion by other substances of each switch, thereby extending the service life of each switch and reducing maintenance costs.

[0058] The working process of the cascade mineralization device 100 provided by the present invention is specifically as follows:

[0059] First, the controller controls the first water collection switch 33 and the monitoring component 4 to open, and controls other switches to close, so that the first water collection chamber 1312, the water collection chamber 14, the water guide chamber 15 and the water outlet 12 are connected. After the water to be mineralized enters the shell 1 through the water inlet 11, it is first filtered once by the second filter element 8, and then flows into the first water passage chamber 1311, and is filtered twice by the first filter element 7, and then mineralized by the first-stage filter element 21. The mineralized water flows into the water collection chamber 14 and the water guide chamber 15 in turn, and flows out through the water outlet 12 after the water quality parameters (including the mineral concentration parameters in the water body) are monitored by the monitoring component 4.

[0060] Then, when mineralization is performed only through the first-stage filter element 21, if the water quality parameter value monitored by the monitoring component 4 is lower than the preset value, the controller controls the first water collection switch 33 to be closed, and at the same time controls the first water collection switch 31 and the second water collection switch 34 to be opened, so that the water in the first cavity 131 that has been mineralized by the first-stage filter element 21 flows into the second water passage cavity 1321 through the first pipe 51, and then is filtered by the first filter element 7 in the second cavity 132, and then is mineralized by the second-stage filter element 22, and flows into the water collection cavity 14 and the water guide cavity 15 in turn through the second water collection switch 34, and flows out through the water outlet 12 after the water quality parameters are monitored by the monitoring component 4.

[0061] Furthermore, when mineralization is performed through the first-stage filter element 21 and the second-stage filter element 22, if the water quality parameter value monitored by the monitoring component 4 is lower than the preset value, the controller controls the second water collection switch 34 to be closed, and at the same time controls the second water collection switch 32 and the third water collection switch 35 to be opened, so that the water mineralized by the second-stage filter element 22 in the second cavity 132 flows into the third water passage cavity 1331 through the second pipe 61, and then is filtered by the first filter element 7 in the third cavity 133, and then is mineralized by the third filter element, and flows into the water collection cavity 14 and the water guide cavity 15 in turn through the third water collection switch 35, and flows out through the water outlet 12 after the water quality parameters are monitored by the monitoring component 4.
