Description

Technical Field

[0001] The present invention relates to the technical field of water purification equipment, and in particular to a valve body, a wastewater valve and water purification equipment. Background Art

[0002] Due to differences in groundwater composition, water quality varies across the country. Currently, water purifiers discharge wastewater through wastewater valves, and the wastewater ratio is fixed, making it unable to adapt to the differences in water quality across the country. Consequently, in areas with good water quality, the same wastewater ratio will result in excessive waste of freshwater resources. In areas with poor water quality, RO membranes cannot reach their normal lifespan and quickly become contaminated and fail. Data shows that RO membranes that can normally be used for three years will become severely contaminated and rapidly fail in areas with high water hardness after as little as four months, ultimately resulting in a failure to produce water. Therefore, existing water purifiers with fixed wastewater ratios cannot adapt to the differences in water quality across the country, leading to rapid contamination of reverse osmosis membranes or waste of freshwater resources. Summary of the Invention

[0003] The main purpose of the present invention is to provide a valve body, a wastewater valve and a water purification device to solve the problem in the prior art that the wastewater valve cannot adjust the wastewater ratio.

[0004] To achieve the above-mentioned objectives, the present invention provides a valve body having a water inlet chamber, multiple water diversion chambers, a water outlet structure and multiple wastewater holes. A water diversion chamber and the water outlet structure are connected through at least one wastewater hole, and the sum of the apertures of the wastewater holes connected by at least two water diversion chambers is different.

[0005] Optionally, the sum of the pore diameters of the wastewater holes communicating with at least two water diversion chambers is within the range of 0.2 mm to 1.2 mm.

[0006] Optionally, a plurality of water diversion chambers are arranged circumferentially around the water inlet chamber.

[0007] Optionally, the water outlet structure is a water outlet cavity to which multiple water diversion cavities are connected, the valve body also has a wastewater outlet, and the water outlet cavity is connected to the wastewater outlet; or, the water outlet structure includes multiple water outlet cavities connected one-to-one with multiple water diversion cavities, the valve body also has multiple wastewater outlets, and the multiple wastewater outlets are connected one-to-one with multiple water outlet cavities.

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figures 1 to 4 As shown, the valve body of this embodiment has a water inlet chamber 121, multiple water diversion chambers 122, a water outlet structure and multiple wastewater holes 15. A water diversion chamber 122 and the water outlet structure are connected through at least one wastewater hole 15, and the sum of the apertures of the wastewater holes 15 connected to at least two water diversion chambers 122 is different.

[0032] When the valve body of this embodiment is used to discharge wastewater, the water inlet chamber 121 is connected to the water diversion chamber 122, and the wastewater passes through the water inlet chamber 121, the water diversion chamber 122 and the wastewater hole 15 in sequence and enters the water outlet structure to realize the discharge of wastewater. In addition, the sum of the apertures of the wastewater holes 15 connected to at least two water diversion chambers 122 is different. By the difference in the water diversion chambers 122 connected to the water inlet chamber 121, different flow rates of water can be realized, thereby realizing different wastewater ratios, which can adapt to the differences in water quality in different regions, and can achieve the normal service life of the RO membrane in areas with poor water quality, and improve the utilization rate of pure water in areas with good water quality, thereby saving fresh water resources, and effectively solving the problem of easy fouling and failure of the RO membrane and waste of fresh water resources caused by a fixed wastewater ratio.

[0033] In this embodiment, the multiple water diversion chambers 122 are independent of each other, and the multiple wastewater holes 15 have different diameters. Each water diversion chamber 122 has the same number of wastewater holes 15 connected to it, which is one. By selecting different water diversion chambers 122 connected to the water inlet chamber, different water flow rates can be achieved. Preferably, the diameter of the wastewater holes 15 is within the range of 0.2 mm to 1.2 mm. As an alternative embodiment, the apertures of the multiple wastewater holes 15 are different, and the number of wastewater holes 15 connected to each water diversion chamber 122 may also be different, thereby achieving a different sum of the apertures of the wastewater holes 15 connected to at least two water diversion chambers 122, thereby achieving water outflow at different flow rates. At this time, the sum of the apertures of the wastewater holes 15 connected to each water diversion chamber 122 is in the range of 0.2mm to 1.2mm, or, the apertures of the multiple wastewater holes 15 are the same, and the number of wastewater holes 15 connected to each water diversion chamber 122 is different, thereby achieving a different sum of the apertures of the wastewater holes 15 connected to at least two water diversion chambers 122. At this time, the sum of the apertures of the wastewater holes 15 connected to each water diversion chamber 122 is in the range of 0.2mm to 1.2mm.

[0034] In this embodiment, the multiple water diversion chambers 122 of the valve body are arranged circumferentially around the water inlet chamber 121 , so that the water inlet chamber 121 can selectively communicate with different water diversion chambers 122 .

[0035] The present invention also provides a wastewater valve, which includes: the above-mentioned valve body.

[0036] In this embodiment, the wastewater valve further includes an adjusting member disposed on the valve body 10 to connect the water inlet chamber 121 with at least one water diversion chamber 122. The adjusting member adjusts the wastewater ratio by switching the water diversion chamber 122 in communication with the water inlet chamber 121. By connecting the water inlet chamber 121 and the water diversion chamber 122 via the adjusting member, wastewater sequentially passes through the water inlet chamber 121, the water diversion chamber 122, and the wastewater hole 15 into the water outlet structure, thereby achieving wastewater discharge. Furthermore, by switching the water diversion chamber 122 via the adjusting member, different wastewater ratios can be achieved.

[0037] In this embodiment, the wastewater valve also includes multiple valve needles 20, which are movably disposed in corresponding water diversion chambers 122 and are pluggable with multiple wastewater holes 15. The valve needles 20 have a closed state in which they are inserted into the wastewater hole 15, and an open state in which they are removed from the wastewater hole 15. When discharging wastewater, the regulating member connects the water inlet chamber 121 with the water diversion chamber 122. The valve needle corresponding to the water diversion chamber 122 is removed from its corresponding wastewater hole 15, opening the wastewater hole 15. Wastewater then passes through the water inlet chamber 121, the water diversion chamber 122, and the wastewater hole 15 in sequence and enters the water outlet structure, achieving wastewater discharge. The valve needle 20 can be inserted into the wastewater hole 15 to clean dirt within the wastewater hole 15, achieving the purpose of self-cleaning and preventing the wastewater hole 15 from clogging. The above-mentioned wastewater valve can both adjust the wastewater ratio and achieve self-cleaning, effectively solving the problem of the wastewater hole being easily clogged in the prior art solenoid valve with adjustable wastewater ratio.

[0038] In this embodiment, multiple valve needles 20 are pluggably arranged in a one-to-one correspondence with multiple wastewater holes 15, simplifying the structure of the valve body and reducing costs. As an alternative embodiment, the number of valve needles 20 is less than the number of wastewater holes 15, and one valve needle 20 is pluggably arranged with two wastewater holes 15.

[0039] In this embodiment, the wastewater valve also includes an elastic member 71 connected to the valve needle 20. Under the action of the water pressure in the water diversion chamber 122, the elastic member 71 is in a compressed state and the valve needle 20 is in an open state; under the action of the reset elastic force of the elastic member 71, the valve needle 20 is in a closed state. The opening and closing of the wastewater hole is achieved by the water pressure in the water inlet chamber 121 and the reset elastic force of the elastic member 71. There is no need to set up a driving mechanism to drive the valve needle to move, which simplifies the overall structure of the valve seat and saves costs. When the water purifier is producing water, the water pressure in the water diversion chamber 122 pushes the valve needle 20 to move and open the wastewater hole 15; when the water purifier is not producing water or the water diversion chamber 122 is switched, the water pressure in the water diversion chamber 122 disappears, and the reset elastic force of the elastic member 71 pushes the valve needle 20 to move to push open the scale in the wastewater hole and close the wastewater hole, which more effectively prevents the wastewater hole from being blocked. Among them, the water purifier not producing water can refer to the water purifier being stopped and on standby.

[0040] In this embodiment, the elastic member is a spring, which is easy to use and low in cost. As an alternative embodiment, the elastic member is an elastic column. In this case, no mounting member is required, and the valve needle is directly connected to the elastic column.

[0041] In this embodiment, the regulating member is a movable member movably provided on the valve body 10, and the movable member has a connecting structure connecting the water inlet chamber 121 and the at least one water diversion chamber 122. When the movable member moves, the connecting structure connects the water inlet chamber 121 and the water diversion chamber 122, and the valve needle corresponding to the water diversion chamber 122 is pulled out from its corresponding wastewater hole 15, opening the wastewater hole 15, and the wastewater passes through the water inlet chamber 121, the water diversion chamber 122 and the wastewater hole 15 in sequence into the water outlet structure, thereby realizing the discharge of wastewater. By switching the water diversion chamber through the movement of the movable member, different wastewater ratios can be achieved. As an alternative embodiment, the regulating member is a multi-way joint, which has an inlet channel and multiple outlet channels connected to the inlet channels. A movable moving part is provided in the multi-way joint, and an inlet channel is connected to at least one outlet channel by movement, or an opening and closing structure is provided at each outlet channel to open the outlet channel through the opening and closing structure.

[0042] In this embodiment, if Figure 2 and Figure 5 As shown, the movable member is a rotating disk 41, and multiple water diversion chambers 122 are arranged around the center of the rotating disk 41. The water inlet chamber is connected to at least one water diversion chamber 122 through the rotating connecting structure of the rotating disk 41. As an alternative embodiment, the movable member is a movable plate, and the multiple water diversion chambers 122 are arranged in sequence along the moving direction of the movable plate.

[0043] In this embodiment, the water outlet structure is a water outlet chamber 13 to which multiple water diversion chambers 122 are connected. The valve body 10 also has a wastewater outlet. The water outlet chamber 13 is connected to the wastewater outlet. During the wastewater discharge process, the wastewater flows into the water outlet chamber 13 after passing through each water diversion chamber 122 and its corresponding wastewater hole, and then flows out from the wastewater outlet. The setting of a water outlet chamber 13 can simplify the structure of the valve body and reduce the difficulty of processing the valve body. As an alternative embodiment, the water outlet structure includes multiple water outlet cavities 13 that are connected to the multiple water diversion cavities 122 in a one-to-one correspondence, and the valve body 10 also has multiple wastewater outlets, and the multiple wastewater outlets are connected to the multiple water outlet cavities 13 in a one-to-one correspondence. During the wastewater discharge process, the wastewater passes through the water diversion cavity 122 and its corresponding wastewater hole and flows into the water outlet cavity 13 corresponding to the water diversion cavity 122, and the wastewater in each water outlet cavity 13 flows out from the corresponding wastewater outlet; or, the water outlet structure includes multiple water outlet cavities 13 that are connected to the multiple water diversion cavities 122 in a one-to-one correspondence, and the valve body 10 also has a wastewater outlet, and the multiple water outlet cavities 13 are connected to the wastewater outlet. During the wastewater discharge process, the wastewater passes through the water diversion cavity 122 and its corresponding wastewater hole and flows into the water outlet cavity 13 corresponding to the water diversion cavity 122, and the wastewater in the multiple water outlet cavities 13 can all flow to the wastewater outlet and then flow out from the wastewater outlet.

[0044] In this embodiment, if Figure 3 As shown, the water diversion chamber 122 is located outside the water outlet chamber 13, and the water inlet chamber 121 is located inside the water outlet chamber 13. At this time, the water inlet chamber 121 is a cylindrical chamber and the water outlet chamber 13 is an annular chamber, which is simpler in layout and simplifies the structure of the valve body.

[0045] In this embodiment, if Figure 1 and Figure 2 As shown, the wastewater valve also includes a valve core 42 fixed on the valve body 10. The valve core 42 is located between the valve body 10 and the turntable 41. The valve core 42 has a water inlet 421 and multiple water outlets 422. The water inlet 421 is connected to the water inlet chamber 121, and the multiple water outlets 422 are connected to the multiple water diversion chambers 122 in a one-to-one correspondence. The provision of the valve core 42 can simplify the structure of the turntable and the valve body and reduce the difficulty of manufacturing. The valve core 42 and the turntable 41 are both made of hard materials, such as ceramics; the turntable 41 and the valve core 42 can rotate relative to each other, and due to the material, they can achieve the function of mutual sealing. Of course, the valve core 42 can also be omitted.

[0046] In this embodiment, the wastewater valve further includes a gland 74, which is fixed to the valve body 10 and presses the rotary disk 41 against the valve body 10. Furthermore, the gland 74 presses the valve core 42 against the valve body 10. The gland 74, the rotary disk 41, and the valve core 42 are sealed by a sealing ring. This ring enhances the seal between the gland 74, the rotary disk 41, and the valve core 42, preventing leakage from the wastewater valve.

[0047] In this embodiment, the valve body 10 and the gland 74 are made of polyformaldehyde or the like. When the turntable 41 rotates relative to the gland 74 , friction occurs between the two. Polyformaldehyde has good wear resistance, which increases the service life of the wastewater valve.

[0048] In this embodiment, if Figure 7 As shown, the outer wall of the valve core 42 is provided with an outwardly protruding anti-rotation protrusion, and the valve body 10 is provided with an anti-rotation port that cooperates with the anti-rotation protrusion. The cooperation between the anti-rotation protrusion and the anti-rotation port limits the rotation of the valve core 42.

[0049] In this embodiment, if Figure 2 As shown, a sealing gasket is provided between the valve core 42 and the valve body 10 , and the sealing gasket is provided with through holes corresponding to a plurality of water diversion chambers, flushing chambers, and water inlet chambers.

[0050] In this embodiment, if Figure 6 As shown, the communication structure is a communication cavity 411. The communication cavity 411 is a communication groove provided on the side of the rotary disk facing the valve core. As an alternative embodiment, if the valve core 42 is not provided, the communication cavity 411 is a U-shaped communication channel.

[0051] In this embodiment, the rotating disk 41 rotates a certain angle, causing the connecting chamber 411 to connect the water inlet chamber 121 with one water diversion chamber 122. The rotating disk 41 rotates another certain angle, causing the connecting chamber 411 to connect the water inlet chamber 121 with another water diversion chamber 122. As an alternative embodiment, the rotating disk 41 rotates a certain angle, causing the connecting chamber 411 to connect the water inlet chamber 121 with one water diversion chamber 122; the rotating disk 41 rotates another certain angle, causing the connecting chamber 411 to connect the water inlet chamber 121 with two water diversion chambers 122; and the rotating disk 41 rotates another certain angle, causing the connecting chamber 411 to connect the water inlet chamber 121 with three water diversion chambers 122.

[0052] In this embodiment, if Figure 8 As shown, the outer diameters of the multiple valve needles 20 are different, and the apertures of the wastewater holes 15 are also different. That is, the flow areas of the multiple wastewater holes 15 are different, and each valve needle corresponds to a different water quality level. When water quality is divided into excellent, standard, and poor, the water quality levels are graded as I, II, and III, respectively. The valve needle 20 with the smallest outer diameter corresponds to the lowest grade of water quality tested, and the valve needle with the largest outer diameter corresponds to the highest grade of water quality tested. Each rotation of the turntable by a certain angle corresponds to a different water diversion chamber, and thus to wastewater holes and valve needles 20 of different sizes, thereby adjusting the wastewater ratio and reducing the number of valve needles. As an alternative embodiment, the outer diameters of the multiple valve needles 20 are the same, and the apertures of the multiple wastewater holes 15 are the same, while the number of valve needles 20 corresponding to the multiple water diversion chambers 122 is different. For example, the first water diversion chamber corresponds to one valve needle and one wastewater hole, the second water diversion chamber corresponds to two valve needles and two wastewater holes, and the third water diversion chamber corresponds to three valve needles and three wastewater holes.

[0053] Specifically, there are three wastewater holes 15 and three valve needles 20. When the water quality is good, the wastewater hole with the smallest flow area is opened, and the other two are closed. When the water quality is standard, the wastewater hole with the middle flow area is opened, and the other two are closed. When the water quality is poor, the wastewater hole with the largest flow area is opened, and the other two are closed. As an alternative embodiment, the number of valve needles and wastewater holes can be two or four or more.

[0054] In this embodiment, the valve needle 20 is cylindrical and coaxially arranged with the wastewater hole 15. Its outer diameter is slightly smaller than the diameter of the wastewater hole 15, facilitating its movement within the wastewater hole. Specifically, the end of the valve needle that engages the wastewater hole has a pointed tip, making it easier for the valve needle to dislodge scale from the wastewater hole.

[0055] In this embodiment, if Figure 3 and Figure 4As shown, the valve body 10 also has a flushing chamber 19, and the water inlet chamber 121 is suitable for connecting to the flushing chamber. Correspondingly, the connecting structure of the wastewater valve is suitable for connecting the water inlet chamber 121 and the flushing chamber 19. When flushing is required, the connecting structure can be connected to the water inlet chamber 121 and the flushing chamber 19 by rotating the turntable. At this time, the water is discharged with a large aperture to achieve the flushing effect. A flushing port 423 corresponding to the flushing chamber 19 is provided on the valve core 42, and the water inlet 421 is located in the middle of the valve core 42, and multiple drains 422 and flushing ports 423 are arranged around the water inlet 421. When there are three water diversion chambers 122, there are also three drains 422, and the three drains correspond to the three water diversion chambers 122 respectively, and the flushing port 423 corresponds to the flushing chamber.

[0056] In this embodiment, the valve body 10 also has a water outlet channel (not shown) connected to the flushing chamber 19. The water outlet structure is connected to the flushing chamber 19, and the water outlet channel is only connected to the flushing chamber 19, resulting in a simpler structure. A wastewater outlet is formed at one end of the water outlet channel. When discharging wastewater, the wastewater flows into the water outlet structure, then flows through the flushing chamber 19, the water outlet channel, and finally flows out of the valve body through the water outlet channel. When flushing, water flows into the flushing chamber 19, then into the water outlet channel, and finally flows out of the valve body through the wastewater outlet of the water outlet channel. As an alternative embodiment, when the water outlet structure is a water outlet cavity 13 and the valve body 10 has a wastewater outlet, the valve body is also provided with a flushing outlet connected to the flushing cavity 19. At this time, no water outlet channel is provided. When discharging wastewater, the wastewater flows into the water outlet cavity 13 and then flows out of the valve body from the wastewater outlet; when flushing, the water flows into the flushing cavity 19 and then flows out of the valve body from the flushing outlet, or, when the water outlet structure includes multiple water outlet cavities 13 and the valve body 10 has a wastewater outlet, the multiple water outlet cavities 13 are all connected with the flushing cavity 19. When discharging wastewater, the wastewater flows into the water outlet cavity 13 and then flows through the flushing cavity 19 and the water outlet channel, and finally flows out of the valve body through the wastewater outlet of the water outlet channel; when flushing, the water flows into the flushing cavity 19 and then flows into the water outlet channel, and finally flows out of the valve body through the wastewater outlet of the water outlet channel, or, when the water outlet structure includes multiple water outlet cavities 13 and when the valve body 10 has multiple wastewater outlets connected to the multiple water outlet cavities 13 in a one-to-one correspondence, the water outlet cavity 13 is not connected to the flushing cavity, and the valve body is also provided with a flushing outlet connected to the flushing cavity 19. At this time, there is no water outlet channel. When discharging wastewater, the wastewater flows into the water outlet cavity 13 and then flows out of the valve body from its corresponding wastewater outlet; when flushing, the water flows into the flushing cavity 19 and then flows out of the valve body from the flushing outlet, or, when the water outlet structure is a water outlet cavity 13 and the valve body 10 has a wastewater outlet, the water outlet cavity 13 is not connected to the flushing cavity 19, and the water outlet cavity 13 and the flushing cavity 19 are respectively connected to the water outlet channel. When discharging wastewater, the wastewater flows into the water outlet cavity and then flows out of the valve body from the water outlet of the water outlet channel and finally flows out of the valve body from the wastewater outlet of the water outlet channel; when flushing, the water flows into the flushing cavity 19 and then flows into the water outlet channel and finally flows out of the valve body from the wastewater outlet of the water outlet channel.

[0057] In this embodiment, if Figure 1 and Figure 2 As shown, the wastewater valve also includes a drive component 30, which is connected to the movable member. The drive component 30 drives the rotary disk 41 to rotate, making control more convenient and thus achieving automatic adjustment of the wastewater ratio. The drive component 30 is a motor, which is easy to use and low in cost.

[0058] In this embodiment, the wastewater valve further includes a fixing seat 72. The first end of the valve needle 20 is pluggably mounted to the wastewater hole 15. The second end of the valve needle 20 is fixed to the fixing seat 72. The end of the fixing seat 72 facing away from the valve needle 20 is connected to the elastic member 71. The water pressure in the water diversion chamber 122 acts on the end of the fixing seat 72 facing the valve needle 20. The fixing seat 72 facilitates the fixing of the valve needle, ensuring its axial movement along the wastewater hole and facilitating the action of water pressure on the fixing seat 72.

[0059] In this embodiment, the valve body 10 further has a plurality of mounting cavities corresponding to the plurality of water diversion cavities 122. The fixing seat 72 and the elastic member 71 corresponding to the water diversion cavities 122 are installed in one mounting cavity. The mounting cavity facilitates the installation of the fixing seat 72 and the elastic member 71.

[0060] In this embodiment, if Figure 2 As shown, the wastewater valve also includes a sealing ring 75. The sealing ring 75 is arranged between the outer wall of the fixed seat 72 and the inner wall of the installation cavity. The sealing ring 75 plays a sealing role, preventing wastewater from flowing into the side where the elastic member is located and affecting the movement of the valve needle, ensuring the normal movement of the valve needle. The sealing ring 75 increases the sealing between the fixed seat 72 and the installation cavity, avoiding the phenomenon of water leakage in the wastewater valve. The outer wall of the fixed seat 72 has an installation ring groove for installing the sealing ring 75, which is convenient for installing the sealing ring and has a good sealing effect. The wastewater valve also includes a cover 73. The cover seals one end of the installation cavity away from the water diversion cavity. One end of the elastic member is sleeved on one end of the fixed seat, and the other end of the elastic member abuts against the cover. The setting of the cover also facilitates the fixing of the other end of the elastic member. The cover is threadedly connected to the valve body, and the threaded connection is simple.

[0061] In this embodiment, the sealing ring 75 is made of wear-resistant rubber. When the valve needle 20 moves, it drives the sealing ring 75 to move relative to the valve body 10. There is friction between the valve body 10 and the sealing ring 75. The wear-resistant rubber has good wear resistance, which extends the service life of the sealing ring 75.

[0062] In this embodiment, the wastewater valve further includes a valve seat 81, which defines an inlet channel and an outlet channel. One end of the inlet channel communicates with the water inlet chamber 121, and one end of the outlet channel communicates with the water outlet chamber 13. The valve seat 81 is designed to facilitate connection with the inlet and outlet pipes. The inlet and outlet channels are L-shaped. The inlet channel connects to the inlet connector 82, and the outlet channel connects to the outlet connector 83. Of course, the valve seat can also be omitted, with the inlet pipe connected directly to the water inlet chamber and the outlet pipe connected directly to the outlet flow channel.

[0063] In this embodiment, the turntable 41 has a connecting hole connected to the motor shaft, and the connecting hole is fixedly connected to the motor shaft. The turntable selects different drain outlets according to the program control, and the motor drives the turntable to rotate. The connecting groove of the turntable is oblong, and the connecting groove covers the corresponding water inlet and drain outlet to achieve different wastewater ratios.

[0064] In this embodiment, if Figure 4 As shown, the valve body 10 has a fluid cavity, in which a first separating cylinder 171 and a second separating cylinder 172 are arranged inside and outside the fluid cavity, a water outlet cavity is formed between the first separating cylinder 171 and the second separating cylinder 172, a water inlet cavity is formed in the first separating cylinder 171, and a plurality of partitions 18 are arranged between the second separating cylinder 172 and the inner wall of the fluid cavity. The partitions 18 divide the cavity between the second separating cylinder 172 and the fluid cavity into a plurality of water diversion chambers and flushing chambers.

[0065] In this embodiment, if Figure 2 As shown, the valve body 10, the valve needle 20, the turntable 41, the valve core 42, the fixed seat 72, the pressure cover 74, the cover 73, the sealing ring 75, and the spring form a valve body assembly. The valve needle 20 is fixed on the fixed seat 72 to form a valve needle assembly. The valve needle assembly is assembled with the spring and assembled inside the valve body.

[0066] The present invention also provides a water purification device, which includes: the above-mentioned wastewater valve.

[0067] In the initial state, multiple valve needles 20 are independently positioned in the multiple water diversion chambers 122 of the valve body 10 and all inserted into their corresponding wastewater holes 15. The multiple valve needles 20 have different diameters. The valve body 10 also has a flushing chamber 19. The multiple drain ports 422 are respectively a first drain port, a second drain port, and a third drain port. The multiple water diversion chambers are respectively a first water diversion chamber, a second water diversion chamber, and a third water diversion chamber. The first drain port corresponds to the first water diversion chamber, the second drain port corresponds to the second water diversion chamber, the third drain port corresponds to the third water diversion chamber, and the flushing port corresponds to the flushing chamber. Different valve needle diameters are used to achieve different wastewater ratios.

[0068] When the water purification device starts working, the motor drives the turntable 41 to rotate according to the water quality detected, and the connecting groove of the turntable 41 rotates with the turntable 41 to select the corresponding first drain outlet, second drain outlet or third drain outlet (such as Figure 3 and Figure 7 As shown), the downward flow of wastewater pushes the spring to drive the valve needle 20 out of the wastewater hole (as shown Figure 2 (as shown); multiple valve needles 20 are configured with different diameters to achieve different wastewater ratios through different water diversion chambers 122. Simultaneously, the "flush" function is selected according to the program. The motor drives the turntable 41 to rotate, and the connecting groove of the turntable rotates with it. The flush port is selected, and in this case, the water flows out with a large aperture, achieving a "flush" effect.

[0069] When the water production is completed and the machine enters the standby state and there is no water flow, the valve needle is reset and inserted into the wastewater hole to clean the dirt in the hole, thereby achieving the purpose of self-cleaning and preventing the wastewater hole from being blocked by dirt.

[0070] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0071] The wastewater valve's multiple valve needles 20, each with different diameters, are independently arranged in multiple water diversion chambers. Based on the detected water quality, a motor drives the turntable 41 to rotate, selecting a different water diversion chamber 122. The downward force of the wastewater pushes the spring to disengage the valve needle 20 from the wastewater hole 15. The multiple valve needles 20 are configured with different diameters, achieving different wastewater flow rates through different water diversion chambers 122. Simultaneously, the "flush" function is selected based on the program, and the motor drives the turntable 41 to rotate, selecting the flush chamber 19, where the water is discharged through a large aperture. While achieving a multi-speed adjustable wastewater ratio, the valve needle can also be used for self-cleaning, preventing wastewater hole clogging. It also provides a flushing function, improving product reliability and effectively resolving the problem of wastewater hole clogging in the wastewater solenoid valve.

[0072] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
