Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, and in particular to a water purification device. Background Art

[0002] Faucets are common products in home life scenes, usually including valves and flow channels. The inlet end of the flow channel is connected to the water pipe, and the outlet end of the flow channel is the water outlet of the faucet. The faucet can be opened and closed by controlling the opening or closing of the flow channel through the valve.

[0003] As people's demands for quality of life become higher and higher, some faucets have begun to be equipped with water purifiers. Specifically, a water purifier is installed between the inlet end of the faucet and the water pipe, and a replaceable filter element is set in the water filter chamber of the water purifier. When the tap water passes through the filter chamber, harmful substances in the water can be filtered out by the filter element, so that purified water can be obtained at the water outlet, ensuring the cleanliness of the water for domestic use.

[0004] However, the disassembly and assembly steps of existing water purifiers are relatively cumbersome. When users replace the filter element or temporarily do not need the water purifier to filter, they often need to spend a lot of time disassembling and installing the water purifier. In addition, the size of the existing water purifier along the water flow direction is too large, which often causes the faucet to be excessively lengthened as a whole, causing inconvenience to the user.

DETAILED DESCRIPTION

[0057] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0058] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present utility model. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0059] The filter chamber of an existing water purifier is usually located between the inlet and outlet ends. Therefore, when the filter chamber needs to be opened to replace the filter element or the water purifier is not needed temporarily, the entire water purifier needs to be removed, which makes it difficult for users to operate. In addition, the filter chamber, the water path of the water purifier and the faucet are distributed in the same direction, which causes the water path to be extended and the faucet to be moved down, further affecting the user experience.

[0060] In order to solve the above technical problems, the utility model provides a water purification device, such as Figures 1 to 6 As shown, the water purification device includes a diverter seat 100, a water filter assembly 200 and a waterway control assembly 300, the diverter seat 100 has an inlet cavity 111 at the top, an outlet cavity 121 at the bottom, a mounting port 131 at one side of the diverter seat 100, and a first water filter channel 141, a second water filter channel 142 and a direct flow channel 143 are also formed in the diverter seat 100, wherein the first water filter channel 141 is connected between the inlet cavity 111 and the mounting port 131, the second water filter channel 142 is connected between the mounting port 131 and the outlet cavity 121, and the direct flow channel 143 is connected between the inlet cavity 111 and the outlet cavity 121;

[0061] The water filter assembly 200 includes a housing 210 and a connector 220. The housing 210 is sealed and connected to the mounting port 131. The filter element 10 can be disposed in the housing 210, and the connector 220 can connect the interior of the filter element 10 with the second water filter channel 142.

[0062] The water channel control assembly 300 can selectively block the first water filtering channel 141 and the direct flow channel 143 .

[0063] In the water purification device provided by the present utility model, the inlet cavity 111 of the diverter seat 100 is used to connect to a water source, and the outlet cavity 121 of the diverter seat 100 is used to connect to a faucet or directly used as a water outlet (that is, the water purification device is directly used as a faucet with a water purification function). The inlet cavity 111 at the top of the diverter seat 100 can be connected to the outlet cavity 121 at the bottom through the first water filter channel 141, the water filter assembly 200 and the second water filter channel 142 in sequence, so that the inflowing tap water is filtered into purified water through the filter element 10 in the water filter assembly 200, and the purified water is output through the outlet cavity 121;

[0064] Furthermore, the water channel control component 300 can selectively block the first water filter channel 141 or the direct current channel 143, so that when the filtering function is needed, the direct current channel 143 can be blocked by the water channel control component 300 to allow the water flow to filter the water component 200; when the filtering function is not needed (for example, in scenarios where the water quality requirements are lower, such as washing rags and brushing shoes), the first water filter channel 141 can be blocked by the water channel control component 300 to allow the inlet chamber 111 and the outlet chamber 121 to be connected through the direct current channel 143, thereby freely switching between the water filtering mode and the non-filtering mode.

[0065] The water purifier provided by the utility model can switch between the water filtering mode and the non-filtering mode, so that the user does not need to frequently disassemble and assemble the water filtering assembly 200, and the water filtering assembly 200 is connected to the installation port 131 located on one side of the diverter seat 100, that is, the water filtering assembly 200 is arranged on the side of the water purifier, so that when replacing the filter element 10, the housing 210 of the water filtering assembly 200 on the side can be disassembled separately without removing the water purifier, thereby improving the convenience of the user in performing operations such as replacing the filter element 10. In addition, the water filtering assembly 200 is located on the side of the water purifier, which can effectively reduce the overall size of the water purifier along the water supply direction (i.e., from the inlet chamber 111 to the outlet chamber 121), thereby keeping the faucet position at a suitable height, further ensuring that the user uses water comfortably and conveniently, and improving the user experience.

[0066] As an optional implementation of the present invention, Figure 7 , Figure 8 As shown, the flow diverter seat 100 includes a top seat 110, a base 120, a mounting seat 130 and a connecting portion 140. An inlet cavity 111 is formed at the top of the top seat 110, and an outlet cavity 121 is formed at the bottom of the base 120. An axial hole 115 penetrating to the bottom of the top seat 110 is also formed on the bottom wall of the top seat 110. The connecting portion 140 is connected between the bottom of the top seat 110 and the top of the base 120 and is located on the side of the axial hole 115. A mounting port 131 is formed on the mounting seat 130. The mounting seat 130 is connected to the connecting portion 140 and the base 120. The first water filter channel 141, the second water filter channel 142 and the direct current channel 143 all pass through the connecting portion 140.

[0067] like Figures 3 to 6 As shown, the water channel control component 300 includes a handle structure 310, a shaft 320 and a sealing structure 330. The handle structure 310 is arranged between the top seat 110 and the base 120, the sealing structure 330 is arranged in the inlet cavity 111, and the shaft 320 is arranged in the shaft hole 115. The handle structure 310 can drive the sealing structure 330 to rotate through the shaft 320, so that the sealing structure 330 selectively blocks the first water filtration channel 141 and the direct current channel 143.

[0068] As an optional implementation of the present invention, Figure 5 , Figure 6 As shown, the axis of the housing 210 is perpendicular to the axes of the top seat 110 and the base 120 .

[0069] As a preferred embodiment of the present invention, Figure 5 , Figure 6 As shown, the handle structure 310 and the water filter assembly 200 are respectively located on opposite sides of the axis of the top seat 110 and the base 120, so that when in use, the surface of the water purification device located between the handle structure 310 and the water filter assembly 200 faces the user, and the handle structure 310 and the water filter assembly 200 can face both sides respectively, freeing up more operating space for the user and further optimizing the user experience.

[0070] In order to ensure the airtightness of the inlet cavity 111, as a preferred embodiment of the present invention, Figure 5 , Figure 6 As shown, a plurality of annular sealing grooves extending around the axis of the rotating shaft 320 are formed on the surface of the rotating shaft 320 , and a rotating shaft sealing ring 321 is arranged in the annular sealing groove. The rotating shaft sealing ring 321 seals the gap between the surface of the rotating shaft 320 and the inner wall of the shaft hole 115 .

[0071] As an optional implementation of the present invention, Figures 3 to 6 As shown, the blocking structure 330 includes a connecting member 331, a blocking member 332, a first elastic member (not shown in the figure) and a limit plate 334. The connecting member 331 is fixedly connected to the top end of the rotating shaft 320, and a first stroke hole 3311 is formed in the connecting member 331. The blocking member 332 and the first elastic member are both arranged in the first stroke hole 3311. The limit plate 334 is located above the connecting member 331, and the limit plate 334 is fixedly connected to the top seat 110. The top end of the first elastic member abuts against the bottom surface of the limit plate 334, and the bottom end of the first elastic member can press the blocking member 332 downward so that the blocking member 332 rotates with the connecting member 331 to the opening position corresponding to the first water filter channel 141 or the direct current channel 143 to block the corresponding opening.

[0072] Specifically, when the water filtering function needs to be turned off, the handle structure 310 can be turned to rotate the blocking member 332 to block the opening of the first water filtering channel 141 at the bottom of the inlet cavity 111, such as Figure 5 , Figure 6 As shown, only the direct flow channel 143 remains connected, so that the water flows out directly without passing through the water filter assembly 200;

[0073] Accordingly, when the water filtering function needs to be activated, the handle structure 310 can be turned to rotate the blocking member 332 to block the opening of the direct current channel 143 at the bottom of the inlet chamber 111, and the first water filtering channel 141 remains open. At this time, water will flow into the water filtering assembly 200 through the first water filtering channel 141, and after filtration, flow out through the second water filtering channel 142 and the outlet chamber 121.

[0074] As an optional implementation manner of the present utility model, the first elastic member is a spring.

[0075] As an optional implementation of the present invention, Figures 3 to 6 As shown, the blocking member 332 is in the shape of a sphere.

[0076] In order to ensure the blocking effect of the blocking member 332 on the corresponding opening, as a preferred embodiment of the present utility model, Figures 7 to 9 As shown, a matching groove 112 is formed on the bottom wall of the inlet cavity 111, and the position of the matching groove 112 corresponds to the position of the first water filtering channel 141 and the direct current channel 143. Figure 5 , Figure 6 As shown, an elastic fitting member 340 is provided in the fitting groove 112, and a fitting through hole connected to the first water filter channel 141 and the direct current channel 143 is formed in the elastic fitting member 340, and the blocking member 332 can block the opening of the fitting through hole to block the openings corresponding to the first water filter channel 141 and the direct current channel 143.

[0077] As a preferred embodiment of the present invention, Figures 3 to 6 As shown, the blocking structure 330 also includes a stopper 335 and a second elastic member (not shown in the figure), and a second travel hole 3312 is formed in the connecting member 331. Figures 7 to 9 As shown, a first limiting groove 113 and a second limiting groove 114 are formed on the bottom wall of the inlet cavity 111, and the limiting member 335 and the second elastic member are both arranged in the second stroke hole 3312. The top end of the second elastic member abuts against the bottom surface of the limiting plate 334, and the bottom end of the second elastic member can press the limiting member 335 downward. The limiting member 335 can enter the first limiting groove 113 when the blocking member 332 rotates to a position corresponding to the first water filter channel 141, and enter the second limiting groove 114 when the blocking member 332 rotates to a position corresponding to the direct current channel 143.
