It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] Most of the faucets currently used in the market are designed with a single water outlet. In the prior art, some faucets are also connected with filter elements to remove impurities in the water, but they cannot switch different water outlet modes according to the needs of users. When users need to use different water sources, they generally need to set up multiple faucets, which brings inconvenience to the installation and construction. The design of multiple faucets for water outlet is also not simple and beautiful, and the user experience is poor.

[0027] In view of this, if Figure 1 As shown in the figure, this embodiment provides a faucet device, including a faucet body 100, the faucet body 100 is provided with a water outlet channel 110 and a water inlet channel 120, and a filter element cavity for installing a mineralized filter element 200 is provided in the faucet body 100. A non-mineralized waterway and a mineralized waterway 151 for allowing water to flow through the mineralized filter element 200 are provided in the faucet body 100; the faucet body 100 is connected to a switching valve 300 for switching any one of the non-mineralized waterway 152 and the mineralized waterway 151 to be in communication with the water outlet channel 110 and the water inlet channel 120. A non-mineralized water path 152 and a mineralized water path 151 are arranged in the faucet body 100. In the non-mineralized water path 152, water flows directly to the water outlet channel 110 without passing through the filter material of the mineralized filter element 200. In the mineralized water path 151, water flows through the filter material of the mineralized filter element 200. The filter material of the mineralized filter element 200 can dissolve trace elements beneficial to the body in the water body, so that the outlet water is mineral water. The user can switch the non-mineralized water path 152 or the mineralized water path 151 to be simultaneously connected with the water outlet channel 110 and the water inlet channel 120 by switching the switching valve 300 as needed. In this way, only one faucet device needs to be set up to realize the switching water outlet of non-mineralized water (which can be pure water) and mineralized water. It can be upgraded at the original faucet installation position without setting multiple faucet installation positions, which brings convenience to the installation and construction. A single faucet can realize the switching of water outlet, the countertop appears simple and beautiful, and the user experience is better.

[0028] Specifically, the faucet body 100 may include a longitudinal tube body 130 and a transverse water outlet 140, one end of the transverse water outlet 140 is connected to the longitudinal tube body 130, and the other end may be provided with a water outlet 141, and the interface of the water inlet channel 120 may be provided at the bottom of the longitudinal tube body 130, so as to facilitate the connection of the water inlet pipeline from the bottom of the countertop. The filter cartridge cavity may be provided in the longitudinal tube body 130, and of course, in some embodiments, the filter cartridge cavity may also be provided in the transverse water outlet 140.

[0029] As a first connection mode of the switching valve 300, the switching valve 300 can be arranged downstream of the filter cartridge cavity along the water flow direction. The water inlet channel 120 is directly connected to the water inlet end of the filter cartridge cavity, and the switching valve 300 is arranged between the water outlet end of the filter cartridge cavity and the water outlet channel 110. The switching valve 300 has two inlet and one outlet interfaces. Of course, the number of inlet and outlet interfaces of the switching valve 300 is not limited to three, and the non-mineralized waterway 152 and the mineralized waterway 151 are not limited to one.

[0030] Specifically, the filter cartridge cavity is provided with a non-mineralized water outlet 201 and a mineralized water outlet 202, the switching valve 300 has a first interface 301 and a second interface 302, the non-mineralized water circuit 152 includes a first pipeline connected between the non-mineralized water outlet 201 and the first interface 301, the mineralized water circuit 151 includes a second pipeline connected between the mineralized water outlet 202 and the second interface 302, the switching valve 300 also has a water outlet interface 303 switched and connected with the first interface 301 and the second interface 302, and the water outlet interface 303 is connected with the water outlet channel 110. The first pipeline and the second pipeline can be hoses. The switching valve 300 can be arranged above the filter cartridge cavity. Through the control of the switching valve 300, the water inlet can be switched and connected with the non-mineralized water outlet 201 and the mineralized water outlet 202, so that the water outlet channel 110 can be switched to flow out non-mineralized water or mineralized water for easy use.

[0031] Specifically, the faucet device includes the mineralized filter element 200, and the filter body of the mineralized filter element 200 is annular, and the annular filter body is divided into two isolated chambers inside and outside the filter element cavity. The non-mineralized water outlet 201 and the mineralized water outlet 202 are respectively connected to one of the two chambers, and the water inlet channel 120 and the non-mineralized water outlet 201 are connected to the same chamber. In this embodiment, the non-mineralized water outlet 201 and the water inlet channel 120 are both connected to the chamber outside the mineralized filter element 200. When non-mineralized water is needed, the non-mineralized water outlet 201 and the water outlet channel 110 are switched to a conducting state, and the mineralized water outlet 202 is closed. The water flowing into the water inlet channel 120 directly flows along the outside of the mineralized filter element 200 through the non-mineralized water outlet 201 to the water outlet channel 110, and the user can use non-mineralized water. When drinking mineralized water, the mineralized water outlet 202 and the water outlet channel 110 are switched to a conducting state, the non-mineralized water outlet 201 is closed, and the water flowing into the water inlet channel 120 is outside the mineralized filter element 200 (outer ring area). It needs to pass through the filter material of the mineralized filter element 200 and enter the inner ring area of ​​the mineralized filter element 200 before it can flow from the mineralized water outlet 202 to the water outlet channel 110. Users can use the mineralized water that has passed through the mineralized filter element 200, and the mineralized water contains minerals dissolved from the mineralized filter element 200.

[0032] Alternatively, as a second connection mode of the switching valve 300, the switching valve 300 can be arranged upstream of the filter cartridge cavity along the water flow direction. The water outlet channel 110 is connected to the water outlet end of the filter cartridge cavity, and the switching valve 300 is arranged between the water inlet end of the filter cartridge cavity and the water inlet channel 120. The switching valve 300 has one inlet and two outlet interfaces. Of course, the number of inlet and outlet interfaces of the switching valve 300 is not limited to three, and the non-mineralized waterway 152 and the mineralized waterway 151 are not limited to one.

[0033] Specifically, a first water inlet and a second water inlet are provided at the bottom of the filter element cavity, the switching valve 300 has a first interface 301 and a second interface 302, the non-mineralized water path 152 includes a first pipeline connected between the first water inlet and the first interface 301, the mineralized water path 151 includes a second pipeline connected between the second water inlet and the second interface 302, the switching valve 300 also has a water inlet interface that is switched and connected with the first interface 301 and the second interface 302, and the water inlet interface is connected with the water inlet channel 120. By setting the switching valve 300, the incoming water can be switched and distributed to the first water inlet or the second water inlet, so that the non-mineralized water path 152 or the mineralized water path 151 is connected to the water inlet channel 120.

[0034] Specifically, the faucet device includes the mineralized filter element 200, and the filter body of the mineralized filter element 200 is annular and is divided into two inner and outer chambers in the filter element cavity, the first water inlet and the second water inlet are respectively connected to one of the two chambers, and the water outlet channel 110 is connected to the same chamber as the non-mineralized water outlet 201. When non-mineralized water is needed, the first water inlet and the water inlet channel 120 are switched to a conducting state, the second water inlet is closed, and the water flowing into the water inlet channel 120 flows through the first water inlet along the outer side of the mineralized filter element 200 to the water outlet channel 110, and the user can use non-mineralized water. When drinking mineralized water, the second water inlet and the water inlet channel 120 are switched to a conductive state, the first water inlet is closed, and the water flowing into the water inlet channel 120 passes through the second water inlet and enters the inner side (inner ring area) of the mineralized filter element 200. It must pass through the filter material of the mineralized filter element 200 and enter the outer ring area of ​​the mineralized filter element 200 before it can flow to the water outlet channel 110. Users can use the mineralized water that has passed through the mineralized filter element 200, and the mineralized water contains minerals dissolved from the mineralized filter element 200.

[0035] Optionally, the switching valve 300 is an electrically controlled valve, such as a solenoid valve or a sliding valve or a rotary valve driven by a motor, and the user can control the switching valve 300 through an electrically controlled switch. In specific applications, the switching valve 300 can also be designed as a manual mechanical valve, and the user can control the on-off switching of the corresponding water channel by manually rotating or toggling.

[0036] Optionally, the water outlet channel 110 and / or the water inlet channel 120 are provided with a flow regulating valve, which can be used to adjust the flow of water outlet or water inlet. The flow regulating valve can be an electric valve or a mechanical regulating valve. In some possible implementations, the switching valve 300 can be optionally integrated with a flow control component, which can be electric or manual to meet different usage requirements.

[0037] In specific applications, a one-way permeable membrane may be provided on the outside or inside of the mineralized filter element 200 to allow water to flow through the filter material of the mineralized filter element 200 in one direction. In this way, the water in the non-mineralized waterway 152 may not contact the mineralized filter element 200, and the water in the mineralized waterway 151 flows from the water inlet side to the water outlet side through the one-way permeable membrane.

[0038] In a specific application, the mineralized filter element 200 may be a carbon rod filter element, a ceramic filter element or a carbon fiber filter element. The mineralized filter element 200 may have a housing, in which the filter element cavity is formed, and corresponding water inlet / outlet interfaces 303 are provided at both ends of the housing to facilitate connection with corresponding mineralized / non-mineralized waterways. The replacement and maintenance of the mineralized filter element 200 is relatively convenient.

[0039] In specific applications, the mineralized filter element 200 can be an integrally formed filter body, or the mineralized filter element 200 includes a first mineralized filter body and a second mineralized filter body. The first mineralized filter body and the second mineralized filter body can be cylindrical and sleeved and connected, and the water flow in the mineralized waterway 151 can flow radially through the first mineralized filter body and the second mineralized filter body in turn.

[0040] In specific applications, the mineralized filter element 200 can be used to provide weakly alkaline drinking water. For example, the first mineralized filter body can be a strong alkaline filter body, and the second mineralized filter body can be a weakly alkaline filter body. The strong alkaline filter body has an inhibitory effect on the dissolution of alkaline minerals in the weakly alkaline filter body, which is beneficial to improving the overall service life of the mineralized filter element 200. The strong alkaline ore of the first mineralized filter body (strong alkali) forms a strong alkaline flow water, which has a relatively high pH value and can meet the requirements of the alkaline water quality demand range (pH value 7 to 9) in the early stage, but because of the rapid dissolution, it is difficult to meet the requirements of the alkaline water quality demand range in the later stage. The weakly alkaline material in the second mineralized filter material 120 forms weakly alkaline water, and its initial pH value is relatively low. The weakly alkaline material itself dissolves slowly and has poor alkalization water quality ability, so the pH value of the water body in the early stage is relatively low, but because the surface is gradually dissolved, the pores inside the weakly alkaline material gradually become connected from closed, and the water flow can not only pass through the surface of the material, but also pass through the inside of the material, which increases the contact area between water molecules and weakly alkaline materials and increases the dissolution rate. Therefore, the pH value can meet the alkaline water quality demand range in the later stage. Since weak alkali can increase the porosity in an alkaline environment, the porosity of weakly alkaline ore is relatively low in the early stage, and the internal porosity is gradually increased under the action of water flow, thereby enhancing its alkalization ability. As the porosity reaches a certain degree, it enters a stable dissolution stage, and at this time, the dissolution ability of the strong alkaline ore just decreases. The combination of the two overcomes the problem of low life of a single alkaline filter material, and can well meet the design purpose of longevity of the mineralized filter element 200, and the pH value of the outlet water can be made in the range of 7.0 to 9.0 throughout the life span. Providing users with long-lasting alkaline water that meets the pH standard range can meet users' high-end needs for drinking water. The mineralized filter element 200 has a long service life, and users do not need to replace the filter element frequently, providing a good user experience.

[0041] In a specific application, for example, the first mineralized filter can be a zinc-containing filter, that is, the first mineralized filter can be a zinc mineralized filter, and zinc is one of the essential trace elements for the human body. The second mineralized filter can be a weakly alkaline filter, which can make the pH value of the water body greater than 7. Weakly alkaline water helps to regulate the pH value in the human body and maintain the normal physiological function of the body. The mineralized filter element 200 can provide weakly alkaline water containing zinc, and the first mineralized filter can dissolve zinc in the water body. The second mineralized filter can be a weakly alkaline filter. When the water flows normally through the first mineralized filter and the second mineralized filter, the zinc element can be dissolved normally. When the water flow stops, the water in the installation cavity cannot be emptied, and the first mineralized filter and the second mineralized filter are in an immersed state. When the mineralized filter element 200 is in an immersed state, if the immersed water body is conventional pure water (water filtered by an RO membrane), the amount of zinc dissolved within a certain period of time will exceed the national standard safety limit, that is, the zinc concentration of the immersed water body does not meet the drinking standard, which is not conducive to human health. In this embodiment, by setting the second mineralized filter as an alkaline filter, the soaking water can be made weakly alkaline, thereby inhibiting the excessive dissolution of zinc in the first mineralized filter, so that the zinc concentration in the soaking water also meets the national standard. The mineralized filter material in the first mineralized filter takes smithsonite as an example. The dissolution reaction of smithsonite in water is: ZnCO 3 =Zn 2+ +CO 3 2- . Zn 2+ The saturated solubility of Zn in pure water can reach 6.0 mg / L, far exceeding the national standard limit of 1.0 mg / L. 2+ and CO 3 2- is precipitated synchronously, CO 3 2- The concentration of Zn can be controlled at the lowest level. 2+ The saturated precipitation concentration is controlled at a low level; when the pH value is around 8.3, CO 3 2- The concentration of Zn 2+ The concentration of the soaking water is also at the lowest level, theoretically calculated to be 0.36 mg / L, which meets the standard limit. By setting the second mineralized filter, the pH value of the water body soaking the filter element can be adjusted to about 8.3, which can prevent the zinc element in the water body from exceeding the set range under soaking conditions. The mechanism of inhibiting the dissolution of zinc elements by soaking in alkaline water can not only make the zinc element dissolve normally when the mineralized water channel 151 flows (normal water flow), but also overcome the technical difficulty that the zinc-containing filter body is prone to excessive zinc elements during soaking.

[0042] The present invention also provides a mineral spring mineralized water purification device, which includes the above-mentioned faucet device and a water purifier, wherein the water inlet channel 120 of the faucet device is connected to the water outlet interface 303 of the water purifier. A pre-filter and an RO membrane filter element may be provided in the water purifier. The water flowing out of the water outlet interface 303 may be purified water. The water outlet interface 303 and the water inlet channel 120 of the faucet device may provide purified water for the faucet device. The faucet device allows users to choose to use purified water or mineralized water containing minerals. Users may control the switching valve 300 as needed to choose to use purified water or mineralized water, that is, users may switch the non-mineralized water path 152 or the mineralized water path 151 to be simultaneously connected to the water outlet channel 110 and the water inlet channel 120 by switching the switching valve 300 as needed. In this way, only one faucet device needs to be set up to realize the switching of non-mineralized water (which may be pure water) and mineralized water. The water outlet can be upgraded at the original faucet installation position without setting multiple faucet installation positions, which brings convenience to installation and construction. A single faucet realizes the switching of water outlet, the countertop appears simple and beautiful, and the user experience is better.

[0043] The present invention provides a faucet device and a mineral water purification device, wherein a non-mineralized water path 152 and a mineralized water path 151 are arranged in the faucet body 100. In the non-mineralized water path 152, water flows directly to the water outlet channel 110 without passing through the filter material of the mineralized filter element 200. In the mineralized water path 151, water flows through the filter material of the mineralized filter element 200. The filter material of the mineralized filter element 200 can dissolve trace elements beneficial to the human body in the water body, so that the water outlet is mineral water. The user can cut the filter material according to the needs. By switching the valve 300, the non-mineralized water path 152 or the mineralized water path 151 is switched to be connected to the water outlet channel 110 and the water inlet channel 120 at the same time. In this way, only one faucet device is needed to realize the switching of the water outlet between non-mineralized water (which can be pure water) and mineralized water. The original faucet installation position can be upgraded without setting multiple faucet installation positions, which brings convenience to the installation and construction.
