Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, specifically to a wastewater valve and water purification equipment. Background Technology

[0002] Due to variations in groundwater composition, water quality differs across the country. Currently, water purifiers discharge wastewater through a fixed wastewater valve, which cannot adapt to the diverse water quality across the country. This leads to excessive waste of freshwater resources in areas with good water quality, while in areas with poor water quality, the RO membrane fails to reach its normal lifespan, rapidly fouling and failing. Data shows that an RO membrane that can normally last three years may become severely fouled and fail rapidly in areas with high water hardness, ultimately resulting in no water output. Therefore, the current technology of using a fixed wastewater valve with a fixed wastewater ratio cannot adapt to the differences in water quality in different regions, leading to problems such as rapid fouling of the reverse osmosis membrane or waste of freshwater resources.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] Furthermore, 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.

[0040] like Figures 1 to 4As shown, the wastewater valve in this embodiment includes a valve body 10 and an adjusting member. The valve body 10 has an inlet chamber 121, multiple water distribution chambers 122, an outlet structure, and multiple wastewater holes 15. A water distribution chamber 122 and an outlet structure are connected through at least one wastewater hole 15. The adjusting member is disposed on the valve body 10 to connect the inlet chamber 121 with at least one water distribution chamber 122. The adjusting member adjusts the wastewater ratio by switching the water distribution chamber 122 connected to the inlet chamber 121.

[0041] When discharging wastewater using the wastewater valve of this embodiment, the regulating component connects the inlet chamber 121 and the distribution chamber 122. The wastewater sequentially passes through the inlet chamber 121, the distribution chamber 122, and the wastewater hole 15 into the outlet structure, thus achieving wastewater discharge. By switching the distribution chamber 122 with the regulating component, different wastewater ratios can be achieved, adapting to water quality differences in different regions. This allows the RO membrane to reach its normal lifespan in areas with poor water quality and improves pure water utilization in areas with good water quality, saving freshwater resources. It effectively solves the problems of RO membrane fouling and failure and freshwater waste caused by a fixed wastewater ratio.

[0042] In this embodiment, the multiple wastewater holes 15 have different diameters, and the number of wastewater holes 15 connected to each water distribution chamber 122 is the same and is one. By adjusting the device to switch between different water distribution chambers 122 connected to the water inlet chamber, different flow rates of water can be achieved. Preferably, the diameter of the wastewater holes 15 is in the range of 0.2mm to 1.2mm. As an alternative implementation, the diameters of the multiple wastewater holes 15 may be different, and the number of wastewater holes 15 connected to each water distribution chamber 122 may also be different, thereby achieving a difference in the sum of the diameters of the wastewater holes 15 connected to at least two water distribution chambers 122, thus achieving different flow rates of water. In this case, the sum of the diameters of the wastewater holes 15 connected to each water distribution chamber 122 is in the range of 0.2mm to 1.2mm. Alternatively, the diameters of the multiple wastewater holes 15 may be the same, but the number of wastewater holes 15 connected to each water distribution chamber 122 may be different, thus achieving a difference in the sum of the diameters of the wastewater holes 15 connected to at least two water distribution chambers 122. In this case, the sum of the diameters of the wastewater holes 15 connected to each water distribution chamber 122 is in the range of 0.2mm to 1.2mm.

[0043] In this embodiment, the wastewater valve further includes multiple valve needles 20, which are movably disposed in corresponding water distribution chambers 122 and pluggably disposed with multiple wastewater holes 15. Each valve needle 20 has a closed state when inserted into a wastewater hole 15 and an open state when pulled out of the wastewater hole 15. The multiple valve needles 20 have different outer diameters, and the multiple wastewater holes 15 have different apertures. When the inlet chamber 121 is connected to the water distribution chamber 122, the valve needle 20 corresponding to the water distribution chamber 122 is pulled out of its corresponding wastewater hole 15, opening the wastewater hole 15 to connect the water distribution chamber 122 with the outlet structure. Wastewater sequentially passes through the inlet chamber 121, the water distribution chamber 122, and the wastewater hole 15 into the outlet structure, thus achieving wastewater discharge. The valve needles 20 can be inserted into the wastewater holes 15 to clean the dirt inside, achieving self-cleaning and preventing blockage of the wastewater holes 15. The aforementioned wastewater valve can both adjust the wastewater ratio and achieve self-cleaning, effectively solving the problem of easy clogging of the wastewater orifice in the existing adjustable wastewater ratio solenoid valve. As an alternative implementation, the multiple valve needles 20 have the same outer diameter, and the multiple wastewater orifices 15 have the same orifice diameter, while the number of valve needles 20 corresponding to the multiple water distribution chambers 122 is different.

[0044] In this embodiment, as Figure 8 As shown, the outer diameters of the multiple valve needles 20 are different, and the diameters of the wastewater holes 15 are also different, meaning the flow areas of the multiple wastewater holes 15 are different. Each valve needle corresponds to a different water quality level. When water quality is divided into superior, standard, and poor, the water quality levels are Class I, Class II, and Class III, respectively. The valve needle 20 with the smallest outer diameter corresponds to the lowest level of water quality being tested, and the valve needle with the largest outer diameter corresponds to the highest level of water quality being tested. Each rotation of the turntable corresponds to a different water distribution chamber, which in turn corresponds to different sizes of wastewater holes and valve needles 20, thereby adjusting the wastewater ratio and reducing the number of valve needles. As an alternative implementation, the outer diameters of the multiple valve needles 20 are the same, and the diameters of the multiple wastewater holes 15 are the same. The number of valve needles 20 corresponding to the multiple water distribution chambers 122 is different. For example, the first water distribution chamber corresponds to one valve needle and one wastewater hole, the second water distribution chamber corresponds to two valve needles and two wastewater holes, and the third water distribution chamber corresponds to three valve needles and three wastewater holes.

[0045] 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 wastewater holes are closed. When the water quality is standard, the wastewater hole with the middle flow area is opened, and the other two wastewater holes are closed. When the water quality is poor, the wastewater hole with the largest flow area is opened, and the other two wastewater holes are closed. As an alternative implementation, there are two or more valve needles and wastewater holes.

[0046] In this embodiment, the valve needle 20 is cylindrical, coaxially arranged with the wastewater hole 15, and the outer diameter of the valve needle 20 is slightly smaller than the diameter of the wastewater hole 15, which facilitates the movement of the valve needle in the wastewater hole. Specifically, the end of the valve needle that mates with the wastewater hole has a pointed tip, which makes it easier for the valve needle to push open the scale in the wastewater hole.

[0047] In this embodiment, multiple valve needles 20 are detachably and 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 implementation, the number of valve needles 20 is less than the number of wastewater holes 15, and one valve needle 20 is detachably and pluggably arranged with two wastewater holes 15.

[0048] In this embodiment, the wastewater valve also includes an elastic element 71 connected to the valve needle 20. Under the water pressure in the water distribution chamber 122, the elastic element 71 is in a compressed state, and the valve needle 20 is in an open state; under the restoring force of the elastic element 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 restoring force of the elastic element 71, eliminating the need for a drive mechanism to move the valve needle, simplifying the overall structure of the valve seat, and saving costs. When the water purifier is producing water, the water pressure in the water distribution 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 distribution chamber 122 is switched, the water pressure in the water distribution chamber 122 disappears, and the restoring force of the elastic element 71 pushes the valve needle 20 to move, pushing open the scale in the wastewater hole and closing the wastewater hole, more effectively preventing the wastewater hole from becoming clogged. Here, "the water purifier is not producing water" can refer to the water purifier being stopped or in standby mode.

[0049] In this embodiment, the elastic element is a spring, which is convenient to use and inexpensive. As an alternative implementation, the elastic element is an elastic column, in which case there is no need to set up a mounting part, and the valve needle is directly connected to the elastic column.

[0050] In this embodiment, the adjusting member is a movable member movably mounted on the valve body 10. The movable member has a communication structure connecting the inlet chamber 121 and at least one water distribution chamber 122. When the movable member moves, the communication structure connects the inlet chamber 121 and the water distribution chamber 122. The valve needle corresponding to the water distribution chamber 122 is pulled out from its corresponding wastewater hole 15, opening the wastewater hole 15. Wastewater sequentially passes through the inlet chamber 121, the water distribution chamber 122, and the wastewater hole 15 into the outlet structure, thus achieving wastewater discharge. By switching the water distribution chambers through the movement of the movable member, different wastewater ratios can be achieved. As an alternative implementation, the adjusting member is a multi-port connector. The multi-port connector has an inlet channel and multiple outlet channels all connected to the inlet channel. The multi-port connector has a movable moving part inside, which connects one inlet channel to at least one outlet channel by movement. Alternatively, each outlet channel has an opening and closing structure to open the outlet channel.

[0051] In this embodiment, as Figure 2and Figure 5 As shown, the movable component is a turntable 41, and multiple water distribution chambers 122 are arranged around the center of the turntable 41. The water inlet chamber is connected to at least one water distribution chamber 122 through the rotational connection structure of the turntable 41. As an alternative embodiment, the movable component is a movable plate, and multiple water distribution chambers 122 are arranged sequentially along the moving direction of the movable plate.

[0052] In this embodiment, the water outlet structure is a single water outlet chamber 13, which is connected to multiple water distribution chambers 122. 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 distribution chamber 122 and its corresponding wastewater hole, and then flows out from the wastewater outlet. The setting of a single water outlet chamber 13 can simplify the structure of the valve body and reduce the processing difficulty of the valve body. As an alternative implementation, the water outlet structure includes multiple water outlet chambers 13 that are connected to multiple water distribution chambers 122 in a one-to-one correspondence. The valve body 10 also has multiple wastewater outlets, which are connected to multiple water outlet chambers 13 in a one-to-one correspondence. During the wastewater discharge process, the wastewater flows into the water outlet chamber 13 corresponding to the water distribution chamber 122 after passing through the water distribution chamber 122 and its corresponding wastewater hole. The wastewater in each water outlet chamber 13 flows out from the corresponding wastewater outlet. Alternatively, the water outlet structure includes multiple water outlet chambers 13 that are connected to multiple water distribution chambers 122 in a one-to-one correspondence. The valve body 10 also has a wastewater outlet, and the multiple water outlet chambers 13 are connected to the wastewater outlet. During the wastewater discharge process, the wastewater flows into the water outlet chamber 13 corresponding to the water distribution chamber 122 after passing through the water distribution chamber 122 and its corresponding wastewater hole. The wastewater in the multiple water outlet chambers 13 can all flow to the wastewater outlet and then flow out from the wastewater outlet.

[0053] In this embodiment, as Figure 3 As shown, the water distribution 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 makes the arrangement simpler and simplifies the structure of the valve body.

[0054] In this embodiment, as 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 rotary table 41. The valve core 42 has an inlet 421 and multiple outlets 422. The inlet 421 is connected to the inlet chamber 121, and the multiple outlets 422 are connected to the multiple distribution chambers 122. The valve core 42 simplifies the structure of the rotary table and the valve body, reducing manufacturing difficulty. Both the valve core 42 and the rotary table 41 are made of rigid materials, such as ceramics. The rotary table 41 and the valve core 42 can rotate relative to each other, and due to the materials, they can achieve a mutual sealing function. Of course, the valve core 42 can also be omitted.

[0055] In this embodiment, the wastewater valve also includes a pressure cap 74, which is fixed to the valve body 10 and presses the turntable 41 against the valve body 10. Furthermore, the pressure cap 74 presses the valve core 42 against the valve body 10. The pressure cap 74 is sealed to the turntable 41 and the valve core 42 by a sealing ring, which increases the sealing performance between the pressure cap 74 and the turntable 41 and the valve core 42, preventing leakage from the wastewater valve.

[0056] In this embodiment, as Figure 7 As shown, the outer wall of the valve core 42 has 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 restricts the rotation of the valve core 42.

[0057] In this embodiment, as Figure 2 As shown, a sealing gasket is provided between the valve core 42 and the valve body 10, and the sealing gasket has through holes corresponding to multiple water distribution chambers, flushing chambers and water inlet chambers.

[0058] In this embodiment, as Figure 6 As shown, the connecting structure is a connecting cavity 411. The connecting cavity 411 is a connecting groove provided on the side of the turntable facing the valve core. As an alternative embodiment, if the valve core 42 is not provided, the connecting cavity 411 is a U-shaped connecting channel.

[0059] In this embodiment, the turntable 41 rotates at a certain angle, and the connecting cavity 411 connects the water inlet cavity 121 with one water distribution cavity 122. The turntable 41 then rotates at another certain angle, and the connecting cavity 411 connects the water inlet cavity 121 with another water distribution cavity 122. As an alternative implementation, the turntable 41 rotates at a certain angle, and the connecting cavity 411 connects the water inlet cavity 121 with one water distribution cavity 122; the turntable 41 then rotates at another certain angle, and the connecting cavity 411 connects the water inlet cavity 121 with two water distribution cavities 122; the turntable 41 then rotates at another certain angle, and the connecting cavity 411 connects the water inlet cavity 121 with three water distribution cavities 122.

[0060] In this embodiment, as Figure 3 and Figure 4 As shown, the valve body 10 also has a flushing chamber 19, and the connecting structure is adapted to connect the inlet chamber 121 and the flushing chamber 19. When flushing is required, the connecting structure can be connected between the inlet chamber 121 and the flushing chamber 19 by rotating the turntable, at which time water is discharged from a large aperture to achieve the flushing effect. The valve core 42 is provided with a flushing port 423 corresponding to the flushing chamber 19. The inlet 421 is located in the middle of the valve core 42, and multiple outlets 422 and flushing ports 423 are arranged around the inlet 421. When there are three water distribution chambers 122, there are also three outlets 422, with the three outlets corresponding to the three water distribution chambers 122 respectively, and the flushing ports 423 corresponding to the flushing chambers.

[0061] In this embodiment, the valve body 10 also has a water outlet channel (not shown in the figure) communicating with the flushing chamber 19. The water outlet structure is connected to the flushing chamber 19, while the water outlet channel is only connected to the flushing chamber 19, resulting in a simpler structure. One end of the water outlet channel forms a wastewater outlet. When discharging wastewater, the wastewater flows into the water outlet structure, then flows through the flushing chamber 19 and the water outlet channel, and finally flows out of the valve body through the wastewater outlet of the water outlet channel. During 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 implementation, when the water outlet structure has one water outlet chamber 13 and the valve body 10 has one wastewater outlet, the valve body also has a flushing outlet communicating with the flushing chamber 19. In this case, no water outlet channel is provided. When discharging wastewater, the wastewater flows into the water outlet chamber 13 and then flows out of the valve body from the wastewater outlet. When flushing, water flows into the flushing chamber 19 and then flows out of the valve body from the flushing outlet. Alternatively, when the water outlet structure includes multiple water outlet chambers 13 and the valve body 10 has one wastewater outlet, all multiple water outlet chambers 13 are communicating with the flushing chamber 19. When discharging wastewater, the wastewater flows into the water outlet chamber 13, then flows through the flushing chamber 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, water flows into the flushing chamber 19, then flows into the water outlet channel, and finally flows out of the valve body through the wastewater outlet of the water outlet channel. Alternatively, when the water outlet structure includes multiple water outlet chambers... When the valve body 10 has multiple wastewater outlets that are connected to the multiple outlet chambers 13 one-to-one, the outlet chambers 13 are not connected to the flushing chambers. The valve body is also provided with a flushing outlet connected to the flushing chamber 19. At this time, there is no outlet channel. When discharging wastewater, the wastewater flows into the outlet chamber 13 and then flows out of the valve body from its corresponding wastewater outlet. When flushing, the water flows into the flushing chamber 19 and then flows out of the valve body from the flushing outlet. Alternatively, when the water outlet structure is one outlet chamber 13 and the valve body 10 has one wastewater outlet, the outlet chamber 13 is not connected to the flushing chamber 19. The outlet chamber 13 and the flushing chamber 19 are respectively connected to the outlet channel. When discharging wastewater, the wastewater flows into the outlet chamber and then flows into the outlet channel. Finally, the wastewater outlet of the outlet channel flows out of the valve body. When flushing, the water flows into the flushing chamber 19 and then into the outlet channel. Finally, the wastewater outlet of the outlet channel flows out of the valve body.

[0062] In this embodiment, as Figure 1 and Figure 2 As shown, the wastewater valve also includes a drive component 30, which is connected to the movable part. The drive component 30 drives the turntable 41 to rotate, making control more convenient and enabling automatic adjustment of the wastewater ratio. The drive component 30 is a motor, which is easy to use and inexpensive.

[0063] In this embodiment, the wastewater valve also includes a fixing seat 72. The first end of the valve needle 20 is detachably disposed from the wastewater hole 15, and the second end of the valve needle 20 is fixed on the fixing seat 72. The end of the fixing seat 72 away from the valve needle 20 is connected to the elastic element 71. The water pressure in the water distribution 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, ensures the axial movement of the valve needle along the wastewater hole, and also facilitates the action of water pressure on the fixing seat 72.

[0064] In this embodiment, the valve body 10 also has multiple mounting cavities that are connected to the multiple water distribution cavities 122 in a one-to-one correspondence. The fixing seat 72 and the elastic element 71 corresponding to the water distribution cavities 122 are installed in one mounting cavity. The mounting cavity facilitates the installation of the fixing seat 72 and the elastic element 71.

[0065] In this embodiment, as Figure 2 As shown, the wastewater valve also includes a sealing ring 75. The sealing ring 75 is positioned between the outer wall of the fixing seat 72 and the inner wall of the mounting cavity. The sealing ring 75 serves to seal, preventing wastewater from flowing into the side where the elastic element is located and affecting the movement of the valve needle, ensuring normal valve needle movement. Furthermore, the sealing ring 75 increases the sealing performance between the fixing seat 72 and the mounting cavity, preventing leakage of the wastewater valve. The outer wall of the fixing seat 72 has an installation groove for installing the sealing ring 75, facilitating installation and providing a good sealing effect. The wastewater valve also includes a cover 73, which seals the end of the mounting cavity away from the water distribution cavity. One end of the elastic element is fitted onto one end of the fixing seat, and the other end of the elastic element abuts against the cover. The cover also facilitates fixing the other end of the elastic element. The cover is threaded to the valve body, providing a simple threaded connection.

[0066] In this embodiment, the sealing ring 75 is made of wear-resistant rubber or the like. When the valve needle 20 moves, it causes 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.

[0067] In this embodiment, the valve body 10 and the pressure cap 74 are made of materials such as polyoxymethylene. When the turntable 41 rotates relative to the pressure cap 74, there is friction between them. Polyoxymethylene has good wear resistance, which improves the service life of the wastewater valve.

[0068] In this embodiment, the wastewater valve also includes a valve seat 81, which has an inlet channel and an outlet channel. One end of the inlet channel is connected to the inlet chamber 121, and one end of the outlet channel is connected to the outlet chamber 13. The valve seat 81 is designed for easy connection to the inlet and outlet pipes. The inlet and outlet channels are L-shaped. The inlet channel is connected to the inlet connector 82, and the outlet channel is connected to the outlet connector 83. Alternatively, the valve seat can be omitted, and the inlet pipe can be directly connected to the inlet chamber, and the outlet pipe can be directly connected to the outlet channel.

[0069] In this embodiment, the turntable 41 has a connection hole for connecting to the motor shaft. The connection hole is fixedly connected to the motor shaft. According to the program control, the turntable selects different drain outlets. The motor drives the turntable to rotate. The connecting groove of the turntable is oblong. The connecting groove covers the corresponding water inlet and drain outlet to achieve different wastewater ratios.

[0070] In this embodiment, as Figure 4 As shown, the valve body 10 has a fluid cavity, and a first partition cylinder 171 and a second partition cylinder 172 are arranged inside and outside the fluid cavity. A water outlet cavity is formed between the first partition cylinder 171 and the second partition cylinder 172, and a water inlet cavity is formed inside the first partition cylinder 171. Several partitions 18 are arranged between the second partition cylinder 172 and the inner wall of the fluid cavity. The partitions 18 divide the cavity between the second partition cylinder 172 and the fluid cavity into multiple water distribution chambers and flushing chambers.

[0071] In this embodiment, as Figure 2 As shown, the valve body 10, valve needle 20, rotary table 41, valve core 42, fixed seat 72, pressure cap 74, sealing cap 73, sealing ring 75, and spring form a valve body assembly. The valve needle 20 is fixed on the fixed seat 72 and forms a valve needle assembly. The valve needle assembly and spring are assembled together and installed inside the valve body.

[0072] In this embodiment, the multiple wastewater holes 15 have different diameters, and different water distribution chambers 122 are switched by rotating the turntable 41 to achieve water flow of different rates. Preferably, the diameter of the wastewater holes 15 is between 0.2 mm and 1.2 mm. As an alternative implementation, the multiple wastewater holes 15 have the same diameter, but the number of wastewater holes 15 corresponding to the multiple water distribution chambers 122 is different.

[0073] The present invention also provides a water purification device, which includes the above-mentioned wastewater valve.

[0074] In the initial state, multiple valve needles 20 are independently installed in multiple water distribution chambers 122 of the valve body 10 and are 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 outlets 422 are designated as a first drain outlet, a second drain outlet, and a third drain outlet. The multiple water distribution chambers are designated as a first water distribution chamber, a second water distribution chamber, and a third water distribution chamber. The first drain outlet corresponds to the first water distribution chamber, the second drain outlet corresponds to the second water distribution chamber, and the third drain outlet corresponds to the third water distribution chamber. The flushing port corresponds to the flushing chamber. Different wastewater ratios are achieved by using different valve needle diameters.

[0075] When the water purification equipment starts working, based on the detected water quality, the motor drives the turntable 41 to rotate. The connecting groove of the turntable 41 rotates along with the turntable 41, selecting the corresponding first, second, or third drain outlet (e.g., ...). Figure 3 and Figure 7As shown), the downward force of the wastewater pushes the spring, causing the valve needle 20 to disengage from the wastewater hole (as shown). Figure 2 (As shown); the diameters of multiple valve needles 20 are differentiated, and different wastewater ratios are achieved through different water distribution chambers 122. At the same time, the "rinsing" function is selected according to the program, and the motor drives the turntable 41 to rotate. The connecting groove of the turntable rotates with the turntable, and the rinsing port can be selected. At this time, the water is discharged with a large diameter, realizing the "rinsing" effect.

[0076] When water production is complete and the system enters standby mode, the valve needle resets and inserts into the wastewater hole to clean out any dirt, thus achieving self-cleaning and preventing the wastewater hole from becoming clogged.

[0077] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0078] The wastewater valve has multiple valve needles 20 of different diameters independently installed in multiple water distribution chambers. Based on the detected water quality, a motor drives a turntable 41 to rotate, selecting a different water distribution chamber 122. The downward force of the wastewater pushes a spring, causing the valve needles 20 to disengage from the wastewater orifice 15. The differentiated diameters of the multiple valve needles 20, through different water distribution chambers 122, achieve different wastewater flow rates. Simultaneously, according to the program selection of the "flushing" function, the motor drives the turntable 41 to rotate, selecting the flushing chamber 19, which is for large-diameter water outlet. While achieving multi-level adjustable wastewater ratios, the valve needles can perform self-cleaning, preventing clogging of the wastewater orifice. This also enables the flushing function, improving product reliability and effectively solving the problem of wastewater orifice clogging in wastewater solenoid valves.

[0079] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
