[0051] Please see Figure 1 , Figure 2 and Figure 3 This application provides a water treatment device 1 for treating raw water to meet user needs. The water treatment device 1 includes an outlet channel 123, a first working channel, and a second working channel, both of which are connected to the outlet channel 123. During the flow of raw water through the first and second working channels, it can undergo filtration, sterilization, softening, or other processes. Afterward, the treated raw water is discharged to the outside through the outlet channel 123 for user use.

[0052] For example, taking water treatment equipment 1 as a water purifier, the first and second working channels are equipped with filter elements with different filtration effects, resulting in different filtration effects for the raw water after it flows through the first and second working channels. Similarly, taking water treatment equipment 1 as a sterilizing water treatment machine, the first and second working channels are equipped with sterilizing elements with different sterilization effects, resulting in different sterilization effects for the raw water after it flows through the first and second working channels. And again, taking water treatment equipment 1 as a water softener, the first and second working channels are equipped with softening elements with different softening effects, resulting in different softening effects for the raw water after it flows through the first and second working channels. The following embodiments all use water treatment equipment 1 as a water purifier as an example for explanation.

[0053] Please refer to the following: Figure 4 The water treatment equipment 1 includes a treatment device 10 and a water circuit board structure 20, which is connected to the treatment device 10. The treatment device 10 has a first working channel, a second working channel and an outlet channel 123, and both the first working channel and the second working channel are connected to the outlet channel 123. The water circuit board structure 20 is connected to the treatment device 10.

[0054] The water treatment equipment 1 has a first working state, a second working state, a third working state, and a closed state. When the water treatment equipment 1 is in the first working state, raw water is treated in the first working channel and then flows to the second working channel, rinsing the second working channel. When the water treatment equipment 1 is in the second working state, raw water is treated in the second working channel and then flows to the first working channel, rinsing the first working channel. When the water treatment equipment 1 is in the third working state, raw water is treated in both the first and second working channels and then flows out through the outlet channel 123 to the outside, supplying water to users. When the water treatment equipment 1 is in the closed state, the water treatment equipment 1 stops working. Of course, the number and states of the channels in the water treatment equipment 1 are not limited to the above; they can be specifically set according to requirements.

[0055] The processing device 10 includes a first processing component 11 and a second processing component 12. The first processing component 11 is provided with a first working channel, and the second processing component 12 is provided with a second working channel and a water outlet channel 123. Both the first working channel and the second working channel are connected to the water outlet channel 123. The water circuit board structure 20 is connected to the processing device 10.

[0056] The processing device 10 also includes a housing 13, which is directly connected to the water circuit board structure 20. The first processing component 11 and the second processing component 12 are both housed in the housing 13 and are arranged sequentially along the central axis of the processing device 10. The first processing component 11 and the second processing component 12 are both connected to the water circuit board structure 20 through the housing 13.

[0057] The first processing unit 11 includes a first processing body and a first processing section. The first processing body has a first processing cavity, and the first processing section is located inside the first processing cavity, dividing the first processing cavity into a first water inlet cavity and a first water outlet cavity. The first processing body is also provided with a first water inlet, which is arranged around the outer periphery of the first water inlet cavity. The first water inlet, the first water inlet cavity, and the first water outlet cavity are sequentially connected to form a first working channel.

[0058] The second processing unit 12 includes a second processing body and a second processing section. The second processing body has a second processing cavity, and the second processing section is located inside the second processing cavity, dividing the second processing cavity into a second water inlet cavity and a second water outlet cavity. The second processing body is also provided with a second water inlet, which is located at the end of the second processing cavity away from the second water outlet cavity. The second water inlet, the second water inlet cavity, and the second water outlet cavity are sequentially connected to form a second working channel.

[0059] The first outlet chamber, the first treatment section, and the first inlet chamber are arranged sequentially along the central axis of the treatment device 10. The second inlet chamber, the second treatment section, and the second outlet chamber are also arranged sequentially along the central axis of the treatment device 10. Figure 4Taking the central axis of the treatment device 10 as an example, in the vertical direction, the second water inlet, the second water inlet cavity, the second treatment section, the second water outlet cavity, the first water outlet cavity, the first treatment section and the first water inlet cavity are arranged in sequence in the vertical downward direction, and the first water inlet is arranged along the circumference of the first water inlet cavity.

[0060] The second processing unit 12 is provided with a central tube, which extends along the central axis of the processing device 10, and the inner wall of the central tube forms a water outlet channel 123. Both the first and second water outlet chambers can be directly connected to the water outlet channel 123. Alternatively, the processing device 10 also has a connecting channel located outside the central tube, connecting the first and second water outlet chambers, both of which are connected to the water outlet channel 123 via the connecting channel. The following embodiments will be described using the example where both the first and second water outlet chambers are connected to the water outlet channel 123 via the connecting channel.

[0061] Please refer to the following: Figure 4 , Figure 6 and Figure 8 In some embodiments, a water passage 124 communicating with the first water inlet is formed between the outer walls of the first processing member 11 and the second processing member 12 and the inner wall of the housing 13. The water passage 124 is arranged around the outer periphery of the first processing member 11 and the second processing member 12.

[0062] In this embodiment, both the first processing component 11 and the second processing component 12 can be filter cartridges for filtration, or they can be resin tanks for softening water, etc. The following embodiments will be described using the example where the first processing component 11 and the second processing component 12 are filter cartridges, with the first processing component 11 being a first filter cartridge, the second processing component 12 being a second filter cartridge, the first processing section being a first filter membrane, and the second processing section being a second filter membrane.

[0063] The first filter membrane divides the first processing chamber into a first inlet chamber and a first outlet chamber, which are independent of each other. The second filter membrane divides the second processing chamber into a second inlet chamber and a second outlet chamber, which are independent of each other.

[0064] When the water circuit board structure 20 is activated, the water treatment equipment 1 switches to the first working state. At this time, the first inlet chamber, the first outlet chamber, the connecting channel, the second outlet chamber, and the second inlet chamber are connected in sequence. The raw water is filtered in the first working channel and flows to the second working channel, and the second filter membrane is backwashed.

[0065] When the water circuit board structure 20 is activated, the water treatment equipment 1 switches to the second working state. At this time, the second inlet chamber, the second outlet chamber, the connecting channel, the first outlet chamber, and the first inlet chamber are connected in sequence. The raw water is filtered in the second working channel and flows to the first working channel, and the first filter membrane is backwashed.

[0066] Specifically, the water treatment equipment 1 also has different water channels, each corresponding to a different operating state (non-closed state). The water channel plate structure 20 is used to switch between different water channels to achieve the switching of different operating states of the water treatment equipment 1.

[0067] Taking water treatment equipment 1 as an example, which has a first working state, a second working state, a third working state, and a closed state, water treatment equipment 1 has a first working water path, a second working water path, and a third working water path. The first working water path corresponds to the first working state, the second working water path corresponds to the second working state, and the third working water path corresponds to the third working state. The water path plate structure 20 can switch between different water paths to realize the switching of the state of water treatment equipment 1.

[0068] When water treatment equipment 1 switches to the first working water path, water path plate structure 20 switches to the first working state; when water treatment equipment 1 switches to the second working water path, water path plate structure 20 switches to the second working state; when treatment device 1 switches to the third working water path, water path plate structure 20 switches to the third working state; when water path plate structure 20 cuts off all water paths, water treatment equipment 1 switches to the off state.

[0069] The following examples all use Figure 1 In this example, water treatment device 1 is a water purifier, and the water treatment device 1 has a first working state (i.e., the first working state), a second working state (i.e., the second working state), a water supply state (i.e., the third working state), and a closed state. When water treatment device 1 switches to the first flushing water path, water circuit board structure 20 switches to the first flushing state; when water treatment device 1 switches to the second flushing water path, water circuit board structure 20 switches to the second flushing state; when treatment device 1 switches to the water supply water path, water circuit board structure 20 switches to the water supply state; when water circuit board structure 20 cuts off all water paths, water treatment device 1 switches to the closed state.

[0070] The water circuit board structure 20 includes a multi-port valve 201 and a water circuit board 202, with both the multi-port valve 201 and the treatment device 10 mounted on the water circuit board 202. In some embodiments, the water circuit board 202 serves only to assemble the multi-port valve 201 and the treatment device 10. In some embodiments, the water circuit board 202 is used to connect the water circuits in the multi-port valve 201 and the treatment device 10.

[0071] Specifically, please refer to the following: Figure 2 , Figure 5 , Figure 7 and Figure 9 In some embodiments, the multi-way valve 201 has a first on state and a second on state, and the multi-way valve 201 includes:

[0072] The multi-way valve 201 includes a valve body assembly 21 and a switching assembly 22. The valve body assembly 21 has a raw water inlet channel 211, a first channel 212, a second channel 213, and a recovery channel 214. The raw water inlet channel 211 is connected to a raw water source. The first channel 212 is connected to the end of the first working channel away from the outlet channel 123. The second channel 213 is connected to the end of the second working channel away from the outlet channel 123. The switching assembly 22 includes a movable valve plate 221 movably coupled to the valve body assembly 21. The movable valve plate 221 is controlled to rotate relative to the valve body assembly 21, enabling the multi-way valve 201 to switch between a first open state and a second open state.

[0073] In the first conducting state, the movable valve plate 221 connects the raw water inlet channel 211 and the first channel 212, disconnects the raw water inlet channel 211 from the second channel 213, and connects the second channel 213 to the recovery channel 214. In the second conducting state, the movable valve plate 221 connects the raw water inlet channel 211 and the second channel 213, disconnects the raw water inlet channel 211 from the first channel 212, and connects the first channel 212 to the recovery channel 214.

[0074] The water treatment equipment 1 has a first working state and a second working state. When the water treatment equipment is in the first working state, the multi-way valve 201 is in the first conducting state, and the raw water is treated in the first working channel and then flows to the second working channel. When the water treatment equipment 1 is in the second working state, the multi-way valve 201 is in the second conducting state, and the raw water is treated in the second working channel and then flows to the first working channel.

[0075] Specifically, taking water treatment equipment 1 as a water purifier as an example, when water treatment equipment 1 is in the first working state, the multi-way valve 201 is in the first conducting state. The raw water inlet channel 211, the first channel 212, the first working channel, the second working channel, the first inlet chamber, the first outlet chamber, the connecting channel, the second outlet chamber, the second inlet chamber, the second channel 213, and the recovery channel 214 are sequentially connected to form the first flushing water path (i.e., the aforementioned first working water path). The raw water is filtered in the first working channel and flows to the second working channel, and performs backwashing on the second treatment component 12. When water treatment equipment 1 is in the second working state, the multi-way valve 201 is in the second conducting state. The raw water inlet channel 211, the second channel 213, the second inlet chamber, the second outlet chamber, the connecting channel, the first outlet chamber, the first inlet chamber, the water passage channel 124, the first channel 212, and the recovery channel 214 are sequentially connected to form the second flushing water path (i.e., the aforementioned second working water path). The raw water is filtered in the second working channel and flows to the first working channel.

[0076] Specifically, when the water treatment equipment 1 is in the first flushing state, the multi-way valve 201 is in the first conducting state. The raw water inlet channel 211, the first channel 212, the first inlet chamber, the first outlet chamber, the connecting channel, the second outlet chamber, the second inlet chamber, the second channel 213, and the recovery channel 214 are connected in sequence to form the first flushing water path. The raw water is filtered in the first working channel and flows to the second working channel, and the second filter membrane is backwashed.

[0077] When the water treatment equipment 1 is in the second flushing state, the multi-way valve 201 is in the second conducting state. The raw water inlet channel 211, the second channel 213, the second inlet chamber, the second outlet chamber, the connecting channel, the first outlet chamber, the first inlet chamber, the water passage channel 124, the first channel 212, and the recovery channel 214 are sequentially connected to form the second flushing water path. The raw water is filtered in the second working channel and flows to the first working channel, and performs backwashing on the first filter membrane. Specifically, the connection between the first channel 212 and the end of the first working channel away from the outlet channel 123 means that the first channel 212 is connected to the first inlet chamber. The connection between the second channel 213 and the end of the second working channel away from the outlet channel 123 means that the second channel 213 is connected to the second inlet chamber.

[0078] The first channel 212, the second channel 213, and the recovery channel 214 can be arranged sequentially along the circumference of the raw water inlet channel 211, or the first channel 212, the second channel 213, the recovery channel 214, and the raw water inlet channel 211 can be arranged arbitrarily on the valve body assembly 21. The specific arrangement can be made according to the requirements.

[0079] Please refer to the following: Figure 6 , Figure 7 , Figure 8 and Figure 9 The valve body assembly 21 includes a valve body 216, a fixed valve plate 215, and a valve cover 217. The valve body 216 is mounted on the water circuit board 202 and has a valve cavity 2161. A valve port communicating with the valve cavity 2161 is opened on the valve body 216. The fixed valve plate 215 is fixed inside the valve cavity 2161. The valve cover 217 is detachably covered at the valve port to close the valve cavity 2161. The raw water inlet channel 211, the first channel 212, the second channel 213, and the recovery channel 214 all pass through the fixed valve plate 215 and the valve body 216. The movable valve plate 221 is rotatably mounted inside the valve cavity 2161 and is stacked on the side of the fixed valve plate 215 facing the valve cover 217. The switching assembly 22 also includes a drive component 222, which is located outside the valve chamber 2161 and is connected to the movable valve plate 221 inside the valve chamber 2161 to drive the movable valve plate 221 to rotate relative to the fixed valve plate 215. The opening and closing of the drive component 222 can be controlled manually or by a controller, preferably by a controller, in order to automate the operation of the water treatment equipment 1.

[0080] Valve body 216 is connected to treatment device 10 via water circuit board 202 and remains relatively stationary with respect to treatment device 10. Water circuit board 202 is provided with inlet 2021 and outlet 2022. Inlet 2021 connects the raw water source and raw water inlet channel 211, and outlet 2022 connects the recovery channel 214 and the outside. Raw water from the raw water source flows into the raw water inlet channel 211 through inlet 2021, and water from the recovery channel 214 flows out to the outside through outlet 2022.

[0081] The water treatment equipment 1 also includes a water pump, which drives raw water from the raw water source into the raw water inlet channel 211. The water pump is electrically connected to the controller and is turned on and off under the control of the controller.

[0082] When the movable valve plate 221 rotates relative to the fixed valve plate 215, connecting the raw water inlet channel 211 and the first channel 212, and disconnecting the raw water inlet channel 211 from the second channel 213, and connecting the second channel 213 to the recovery channel 214, the water treatment equipment 1 switches to the first flushing state. At this time, under the action of the water pump, raw water flows sequentially through the raw water inlet channel 211, the first channel 212, the first inlet chamber, the first outlet chamber, and the connecting channel into the second outlet chamber, and performs a backwash on the second filter membrane. After flushing, the flushing water formed after flushing is recovered by an external container through the second inlet chamber, the second channel 213, and the recovery channel 214. The flow direction of the raw water is as follows: Figure 6 and Figure 7 The arrows are a1→a6→a7→b13→b14→b15→b16→b17→b18→b19→b20→b21→c5→c6→c7→c8→a8→a9→a10, or as shown by the arrows a1→a6→a7→b13→b14→b15→b16→b17→b18→b22→b23→b24→c9→c10→c7→c8→a8→a9→a10.

[0083] When the movable valve plate 221 continues to rotate relative to the fixed valve plate 215 in the original direction, it can connect the raw water inlet channel 211 and the second channel 213, and disconnect the raw water inlet channel 211 from the first channel 212. When it connects the first channel 212 to the recovery channel 214, the water treatment equipment 1 switches to the second flushing state. At this time, under the action of the water pump, the raw water flows sequentially through the raw water inlet channel 211, the second channel 213, the second inlet chamber, the second outlet chamber, and the connecting channel into the first outlet chamber, rinsing the first filter membrane. After rinsing, the flushing water formed after rinsing is recovered through the first inlet chamber, the water passage 124, the first channel 212, and the recovery channel 214. The flow direction of the raw water is as follows: Figure 8 and Figure 9The arrows are a13→a14→a15→c11→c12→c13→c14→c15→b25→b26→b27→b28→b29→b30→b31→b32→a16→a17→a18, or as shown by the arrows a13→a14→a15→c11→c12→c17→c18→c16→b33→b34→b35→b28→b29→b30→b31→b32→a16→a17→a18.

[0084] By setting up the raw water inlet channel 211, the first channel 212, the second channel 213 and the recycling channel 214, the water circuit within the water treatment equipment 1 can be switched, thereby enabling the switching of different states of the water treatment equipment 1. The switching method is simple and easy to operate, providing a superior user experience.

[0085] In some embodiments of this application, the moving valve plate 221 is provided with a first guiding groove 2211 and a second guiding groove 2212; when in the first guiding state, the first guiding groove 2211 guides the raw water inlet channel 211 and the first channel 212, and the second guiding groove 2212 guides the second channel 213 and the recovery channel 214; when in the second guiding state, the first guiding groove 2211 guides the raw water inlet channel 211 and the second channel 213, and the second guiding groove 2212 guides the first channel 212 and the recovery channel 214.

[0086] The first guide groove 2211 and the second guide groove 2212 are formed by the recess of the moving valve plate 221 toward the fixed valve plate 215. The first guide groove 2211 can be arc-shaped, Y-shaped, V-shaped or other shapes, and the second guide groove 2212 can be arc-shaped, U-shaped or other shapes, which can be set according to the requirements.

[0087] When the multi-way valve 201 is in the first conducting state, the orthographic projection of the first guiding groove 2211 on the fixed valve plate 215 has a portion that falls into the raw water inlet channel 211 and the first channel 212, so that the raw water inlet channel 211 can be connected to the first channel 212 through the first guiding groove 2211. At the same time, the orthographic projection of the second guiding groove 2212 on the fixed valve plate 215 has a portion that falls into the second channel 213 and the recovery channel 214, so that the second channel 213 can be connected to the recovery channel 214 through the second guiding groove 2212.

[0088] In this way, raw water can flow into the first filter membrane through the raw water inlet channel 211, the first guide groove 2211, and the first channel 212, and after being filtered by the first filter membrane, it washes the second filter membrane. The wash water formed after washing can flow out to the outside of the water treatment equipment 1 through the second inlet chamber, the second channel 213, and the recovery channel 214 and be collected. The flow direction of the raw water is as follows: Figure 6 and Figure 7 The arrows are a1→a6→a7→b13→b14→b15→b16→b17→b18→b19→b20→b21→c5→c6→c7→c8→a8→a9→a10, or as shown by the arrows a1→a6→a7→b13→b14→b15→b16→b17→b18→b22→b23→b24→c9→c10→c7→c8→a8→a9→a10.

[0089] When the multi-way valve 201 is in the second open state, the orthogonal projection of the first guide groove 2211 on the fixed valve plate 215 includes a portion falling into the raw water inlet channel 211 and the second channel 213, so that the raw water inlet channel 211 can be connected to the second channel 213 through the first guide groove 2211. Simultaneously, the orthogonal projection of the second guide groove 2212 on the fixed valve plate 215 includes a portion falling into the first channel 212 and the recovery channel 214, so that the first channel 212 can be connected to the recovery channel 214 through the second guide groove 2212. Thus, raw water can flow into the second treatment unit 12 through the raw water inlet channel 211, the first guide groove 2211, and the second channel 213, and after being treated by the second filter membrane, it rinses the first filter membrane. The rinse water formed after rinsing can flow out to the outside of the water treatment equipment 1 and be collected through the first inlet chamber, the water passage 124, the first channel 212, the second guide groove 2212, and the recovery channel 214. The direction of the raw water flow is as follows Figure 8 and Figure 9 The arrows are a13→a14→a15→c11→c12→c13→c14→c15→b25→b26→b27→b28→b29→b30→b31→b32→a16→a17→a18, or as shown by the arrows a13→a14→a15→c11→c12→c17→c18→c16→b33→b34→b35→b28→b29→b30→b31→b32→a16→a17→a18.

[0090] By setting the first guide groove 2211 and the second guide groove 2212, the connection or disconnection between the raw water inlet channel 211 and one of the first channel 212 and the second channel 213 can be achieved simply by operating the rotating valve plate 221. It can also be achieved by connecting or disconnecting the recovery channel 214 and the other of the first channel 212 and the second channel 213. The operation is simple and convenient.

[0091] In some embodiments, the first guide groove 2211 includes a water inlet 22111, a first flow channel 22112 and a second flow channel 22113, both of which are connected to the water inlet 22111. The included angle between the first flow channel 22112 and the second flow channel 22113 is K, 60°≤K≤120°, and the orthographic projection of the water inlet 2211 and the raw water inlet channel 211 in the extension direction of the central axis of the moving valve plate 221 at least partially overlaps.

[0092] When in the first conducting state, the second flow channel 22113 connects the raw water inlet channel 211 and the first channel 212;

[0093] When in the second conduction state, the first flow channel 22112 conducts the raw water inlet channel 211 and the second channel 213.

[0094] The included angle K between the first flow channel section 22112 and the second flow channel section 22113 is preferably 90° or close to 90°. The first flow channel section 22112 and the second flow channel section 22113, together with the water inlet section 22111, form a V-shaped structure. The orthographic projection of the water inlet section 22111 and the raw water inlet channel 211 in the direction of extension of the central axis of the moving valve plate 221 at least partially overlaps, so that the water inlet section 22111 can always be connected to the raw water inlet channel 211.

[0095] When the water treatment equipment 1 is in the first flushing state, raw water can flow into the first treatment unit 11 through the raw water inlet channel 211, the inlet section 22111, the second flow channel section 22113, and the first channel 212, and after being treated by the first filter membrane, it flushes the second filter membrane. The flushing water formed after flushing can flow out to the outside of the water treatment equipment 1 through the second inlet chamber, the second channel 213, and the recovery channel 214 and be collected.

[0096] When the water treatment equipment 1 is in the second flushing state, raw water can flow into the second treatment unit 12 through the raw water inlet channel 211, the inlet section 22111, the first flow channel section 22112, and the second channel 213, and then flush the first filter membrane after being treated by the second filter membrane. The flushing water formed after flushing can flow out to the outside of the water treatment equipment 1 and be collected through the first inlet chamber, the water passage 124, the first channel 212, the second guide groove 2212, and the recovery channel 214.

[0097] By setting the first guide groove 2211, which includes a water inlet 22111, a first flow channel 22112 and a second flow channel 22113 that are all connected to the water inlet 22111, the first flow channel 22112 and the second flow channel 22113 are set at acute angles, and the orthographic projection of the water inlet 22111 and the raw water inlet channel 211 in the extension direction of the central axis of the moving valve plate 221 at least partially overlaps, when the water treatment equipment 1 is in working state, it can be ensured that the raw water source can be supplied to the first working channel or the second working channel through the raw water inlet channel 211 and the water inlet 22111, and that the flushing water after rinsing can flow out through the recycling channel 214.

[0098] In some embodiments, the second guide groove 2212 is an arc-shaped groove and is arranged around the periphery of the first guide groove 2211. The water inlet 22111, the second guide groove 2212 and the raw water inlet channel 211 are arranged concentrically. The first flow channel 22112 and the second flow channel 22113 are symmetrically distributed on opposite sides of a radial line R1 of the moving valve plate 221, and the second guide groove 2212 is axially symmetrical about the radial line R1.

[0099] The concentric arrangement of the water inlet section 22111, the second guide groove 2212, and the raw water inlet channel 211 means that the central axis of the moving valve plate 221 passes through the center of the water inlet section 22111, the second guide groove 2212, and the raw water inlet channel 211.

[0100] By setting the second guide groove 2212 as an arc-shaped groove and surrounding the periphery of the first guide groove 2211, and the water inlet 22111, the second guide groove 2212 and the raw water inlet channel 211 are concentrically arranged, the first flow channel 22112 and the second flow channel 22113 are symmetrically distributed on both sides of the radial line R1 of the moving valve plate 221, and the second guide groove 2212 is axially symmetrical about the radial line R1. During the rotation of the moving valve plate 221, the accuracy and reliability of water circuit switching can be further improved.

[0101] In some embodiments, the multi-way valve 201 further includes a third conducting state. When in the third conducting state, the moving valve plate 221 conducts the raw water inlet channel 211 and the first channel 212, and conducts the raw water inlet channel 211 and the second channel 213.

[0102] The movable valve plate 221 is controlled to rotate relative to the valve body assembly 21 so that the multi-way valve 201 can switch between any two of the first open state, the second open state, and the third open state.

[0103] The water treatment equipment 1 also has a third working state. When the water treatment equipment 1 is in the third working state, the multi-way valve 201 is in the third conducting state, and the raw water can be treated in the first working channel and the second working channel respectively before flowing into the outlet channel 123. At this time, the raw water inlet channel 211, the first channel 212, the first inlet chamber, the first outlet chamber, the connecting channel, and the outlet channel 123 form a first treatment water path (one of the above-mentioned third working water path). The raw water can flow into the first treatment unit 11 through the first channel 212, and after treatment, it flows out through the outlet channel 123 to supply water to users. In addition, the raw water inlet channel 211, the second channel 213, the second inlet chamber, the second outlet chamber, the connecting channel, and the outlet channel 123 form a second treatment water path (another of the above-mentioned third working water path). The raw water flows into the second treatment unit 12 through the second channel 213, and after treatment, it also flows out through the outlet channel 123 to supply water to users.

[0104] By setting the valve body assembly 21 and the switching assembly 22, the multi-way valve 201 can automatically switch between the first conducting state, the conducting state and the third conducting state, thereby realizing the switching of multiple states of the water treatment equipment 1 and providing a better user experience.

[0105] Please refer to the following: Figure 4 and Figure 5 In some embodiments, the moving valve plate 221 is provided with a first guiding groove 2211; when in the third guiding state, the first guiding groove 2211 guides the raw water inlet channel 211 and the first channel 212, and also guides the raw water inlet channel 211 and the second channel 213.

[0106] Specifically, when in the third conducting state, the first flow channel 22112 is connected to the first channel 212, and the second flow channel 22113 is connected to the second channel 213.

[0107] When water treatment equipment 1 is in its third operating state, under the action of the water pump, raw water flows into the first guide channel 2211 and is divided within it. A portion of the water is sequentially processed through the first flow channel 22112, the first channel 212, and the first working channel before being discharged through the outlet channel 123. The remaining portion is sequentially processed through the second flow channel 22113, the second channel 213, and the second working channel before being discharged through the outlet channel 123. The flow direction of the raw water is as follows: Figure 4 and Figure 5The arrows are a1→a2→a4→b1→b2→b3→b4→b5→b6→b7→b8→b9→d1→d2→d3, or as shown by the arrows a1→a2→a4→b1→b2→b3→b4→b5→b6→b10→b11→b12→d1→d2→d3, or as shown by the arrows a1→a3→a5→c1→c2→c3→c4→d2→d3.

[0108] By setting the first guide groove 2211, the moving valve plate 221 can rotate relative to the valve body assembly 21 to connect the raw water inlet channel 211 with the first channel 212, and can also connect the raw water inlet channel 211 with the second channel 213, making the state switching operation of the water treatment equipment 1 simple and convenient.

[0109] Please see Figure 10 In some embodiments, the water treatment device 1 also has a closed state. When the water treatment device 1 is in the closed state, only the raw water inlet channel 211 is connected to the first guide channel 2211. The moving valve plate 221 closes the first channel 212, the second channel 213, and the recovery channel 214. Therefore, all water passages in the water treatment device 1 are closed, and the water treatment device 1 cannot supply treated raw water, nor can it backwash the first treatment component 11 and the second treatment component 12. The flow direction of the raw water is as follows: Figure 10 As shown by the middle arrow a12→a10, or as shown by the arrow a12→a11.

[0110] In actual operation, when water treatment equipment 1 is turned on, it is generally in the third working state, and water treatment equipment 1 can supply treated clean water. After filtration for a period of time, the driving component 222 drives the valve plate 221 in the first direction (clockwise or counterclockwise). Figure 5 For example, when the first direction is clockwise (A), the water treatment device 1 switches to the first operating state, enabling it to backwash the second treatment component 12. Next, the drive unit 222 continues to drive the valve plate 221 to rotate in the first direction, switching the water treatment device 1 to the closed state and stopping its operation. Afterwards, the drive unit 222 continues to drive the valve plate 221 to rotate in the first direction, switching the water treatment device 1 to the second operating state, enabling it to backwash the first treatment component 11. Finally, the drive unit 222 drives the valve plate 221 to continue rotating in the first direction, switching the water treatment device 1 to the water supply state.

[0111] In some embodiments of this application, the driving component 222 is a motor, and the switching component 22 further includes a rotating disk 223. The rotating disk 223 is sandwiched between the side of the moving valve plate 221 facing away from the fixed valve plate 215 and the valve cover 217. The rotating shaft of the motor passes through the valve cover 217, the rotating disk 223 and the moving valve plate 221, and drives the rotating disk 223 and the moving valve plate 221 to rotate.

[0112] By setting the driving component 222 to drive the moving valve plate 221 to rotate, the space required for the moving valve plate 221 to rotate remains almost unchanged during the state switching process. This helps to reduce the internal volume of the valve cavity 2161 and facilitates a reduction in the size of the valve body assembly 21. The rotating disk 223 can press the moving valve plate 221 and the fixed valve plate 215 together, ensuring a tight fit between them. This prevents water leakage between the various water paths inside the multi-way valve 201 and guarantees the reliability of water supply and flushing in the water treatment equipment 1.

[0113] In some embodiments, valve body assembly 21 includes a limiting element (not shown) configured to limit the movement of valve disc 221 when the water treatment device 1 is in different states.

[0114] The limiting element is located inside the valve cavity 2161 and is connected to the inner wall of the valve cavity 2161 or the inner surface of the valve cover 217 facing the moving valve plate 221.

[0115] For example, in some embodiments, the limiting member is, for instance, a retractable structure. When the movable valve plate 221 rotates to a position corresponding to any state, the limiting member extends to press the movable valve plate 221 against the fixed valve plate 215, preventing the movable valve plate 221 from continuing to rotate. Thus, the multi-way valve 201 can maintain its desired state and operate. When the water treatment device 1 needs to switch states, the limiting member retracts and separates from the movable valve plate 221, allowing the movable valve plate 221 to rotate relative to the fixed valve plate 215, thereby allowing the multi-way valve 201 to switch to the next operating state. In other embodiments, the limiting member can also be, for example, a gripper structure. When the movable valve plate 221 rotates to a position corresponding to any state, the limiting member clamps the movable valve plate 221 to prevent it from continuing to rotate. When the multi-way valve 201 needs to switch states, the limiting member opens and separates from the moving valve plate 221, so that the moving valve plate 221 can rotate relative to the fixed valve plate 215, and the multi-way valve 201 switches to the next working state.

[0116] Of course, the structure of the limiting component can be, but is not limited to, the one mentioned above. It can also be other limiting structures. It is only necessary to ensure that when the moving valve plate 221 rotates and the multi-way valve 201 switches to the desired state, the limiting component can restrict the moving valve plate 221 from continuing to rotate.

[0117] By setting a limit component, the risk of the moving valve plate 221 continuing to rotate when it reaches the desired position can be reduced, so that the multi-way valve 201 can maintain the desired state and work, thus having better working reliability.

[0118] In some embodiments, the water circuit board 202 is further provided with a water supply channel 218, which connects the water outlet channel 123 and the external water supply channel. When the external water supply channel is opened and water is needed, the water treatment device 1 switches to the third working state; the treated clean water in the water outlet channel 123 can be used for water supply through the water supply channel 218 and the external water supply channel. When the treatment device 10 in the multi-way valve 201 needs to be flushed, the external water supply channel is closed, and the water treatment device 1 switches to the first flushing state or the second flushing state.

[0119] The opening and closing of the water supply channel 218 is not related to the rotation of the moving valve plate 221; it is only related to the opening and closing of the external water supply circuit.

[0120] By setting a control valve to control the opening and closing of the water supply channel 218, the opening and closing of the water outlet channel 123 can be controlled. Compared with the opening and closing of the water outlet channel 123 being controlled by the moving valve plate 221 and the fixed valve plate 215, the design difficulty of the moving valve plate 221 and the fixed valve plate 215 can be reduced, resulting in a lower manufacturing cost of the water treatment equipment 1.

[0121] The aforementioned multi-way valve 201, by setting up a raw water inlet channel 211, a first channel 212, a second channel 213 and a recovery channel 214, can realize the switching of water circuits within the water treatment equipment 1, thereby realizing the switching of different states of the water treatment equipment 1. The switching method is simple and easy to operate, and has a better user experience.

[0122] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0123] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
