[0046] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] In the description of the embodiments of the present application, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0049] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0051] Hard water can have many effects on daily life and household equipment. For example, it can reduce the washing effect, accumulate in the water pipes and reduce the water flow, damage the performance and life of the equipment, and cause skin problems. Therefore, people use water softening equipment to treat tap water in daily life. Using water softening equipment can effectively remove minerals in hard water, improve water quality, and enhance the quality of life. The treatment principle of water softening equipment is usually to remove calcium and magnesium ions in water through the process of ion exchange, thereby converting hard water into soft water.

[0052] One of the common methods is to use resin for treatment. This resin is a polymer substance with a special structure and a positive charge on its surface. When hard water passes through the resin particles, the calcium and magnesium ions in it will adsorb to the positive charge on the resin surface and replace the original sodium ions on the resin. After a period of time, the resin particles gradually become saturated. At this time, it is necessary to clean the resin particles by absorbing salt water, and regenerate the resin particles by replacing the adsorbed ions. Usually, the salt water after cleaning the resin particles will be discharged through the sewage channel to prevent the salt water from entering the valve body and the water outlet.

[0053] In the related art, the opening of the sewage discharge channel is controlled by a solenoid valve. The solenoid valve realizes the opening or closing of the channel by electric control. The remoteness of the electromagnetic control makes it susceptible to electromagnetic interference and has low reliability. In addition, the solenoid valve is easy to generate heat when working, and a high temperature is generated. A heat dissipation structure needs to be set to dissipate heat, which makes the overall complexity higher. Moreover, the solenoid valve needs to be controlled by an electrical signal, which makes the entire control system more complicated, increasing the difficulty of preparation and manufacturing cost.

[0054] For problems in related technologies, see Figure 1-Figure 3 As shown, the utility model provides a sewage discharge system, which is used to cooperate with the sewage discharge passage in the first valve body 300, including a rotating component 110 and a pressure rod assembly 200; the pressure rod assembly 200 is arranged on one side of the rotating component 110, and a protrusion 130 is provided on the rotating component 110, and the protrusion 130 can squeeze the pressure rod assembly 200 to open the sewage discharge channel 310. In the normal state, the sewage discharge channel 310 is in a closed state, and only when sewage discharge is required, the sewage discharge channel 310 will be opened for sewage discharge operation. In this embodiment, in the normal state, the protrusion 130 does not contact the pressure rod assembly 200. When sewage discharge operation is required, the rotation of the rotating component 110 makes the protrusion 130 abut against the sewage discharge pressure rod, and when abutting, a thrust can be generated on the pressure rod assembly 200, so that the pressure rod assembly 200 moves, and the pressure rod assembly 200 can open the sewage discharge channel 310 after the movement. The whole process is mechanical transmission control, which will not be affected by factors such as electromagnetic interference, thereby improving the reliability of the device.

[0055] It is understandable that the sewage discharge pressure rod is arranged in the sewage discharge channel 310, and the pressure rod assembly 200 can close the sewage discharge channel 310 in normal state, and the sewage discharge channel 310 is opened only when the sewage discharge channel 310 needs to be opened, and the protrusion 130 is opened to realize the opening of the sewage discharge channel 310. In addition, in this embodiment, the pressure rod assembly 200 can be a conventional sewage discharge pressure rod, and the conventional sewage discharge pressure rod includes a rod body, and one end of the rod body has a sealing head. When it is not necessary to open, the sealing head can realize the blocking of the sewage discharge channel 310, and when it is necessary to open, the sewage discharge channel 310 is opened through the action of external force. For the specific sewage discharge pressure rod, those skilled in the art should know its specific structure, so it will not be further described.

[0056] In specific settings, the sewage system of this embodiment is used in a water softener, and can realize the opening of the sewage channel 310 in the water softener. For example, in specific applications, the position with the protrusion 130 on the rotating component 110 is configured as a salt absorption position, and is controlled by a control system, that is, when the control system sends a signal that salt absorption is required, the rotating component 110 can be rotated, and the protrusion 130 is abutted against the pressure rod assembly 200 by rotation, thereby realizing the opening of the sewage channel 310. When the sewage channel 310 is not required to be opened, the rotating component 110 is controlled to rotate so that the protrusion 130 is misaligned with the pressure rod assembly 200, and the pressure rod assembly 200 can realize the closing of the sewage channel 310 again.

[0057] It can be understood that in this embodiment, the opening of the drain channel 310 is achieved by setting the protrusion 130 on the rotating component 110. The overall structure is simple and efficient, and can respond quickly to achieve the rapid opening of the drain channel 310. The opening of the drain channel 310 is achieved by mechanical transmission, which has higher reliability and anti-interference ability.

[0058] According to an embodiment provided by the utility model, there are multiple protrusions 130, and the protrusions 130 are arranged at intervals. In the overall product, sewage discharge is often required in multiple states. In this embodiment, multiple protrusions 130 are provided on the rotating component 110 to achieve sewage discharge in different states, thereby improving the applicability of the sewage discharge system in this example.

[0059] For specific settings, see Figure 3As shown, two protrusions 130 are provided on the rotating component 110, and the two protrusions 130 are respectively located at different positions. Through the distribution of different positions, the two protrusions 130 can respectively control the opening of the sewage discharge channel 310 in at least two states. Of course, the protrusions 130 can also be three, four, etc., and usually the protrusions 130 can correspond to different states by different distribution positions. The description drawings of this application only illustrate the method of two protrusions 130.

[0060] In a specific application, the two protrusions 130 have the same structure and the same material. Of course, the two protrusions 130 may also have different structures. Figure 3 As shown. In some examples, the minimum distances between the plurality of protrusions 130 and the abutting ends of the pressure rod assembly 200 are substantially the same. Theoretically, the minimum distances between the plurality of protrusions 130 and the pressure rod assembly 200 are equal, but due to processing and assembly, there are often certain errors, so the minimum distances can be substantially the same. It is understandable that the minimum distance can reflect the depth of the action of the pressure rod assembly 200. Generally speaking, the pressure rod assembly 200 has a fixed action depth to achieve complete sealing of the drain channel 310. By limiting the equal minimum distance, the drain channel 310 can be stably opened when opened, and can ensure that the opening is in a fully open state, thereby improving the stability of its opening.

[0061] According to an embodiment provided by the utility model, see Figure 1 As shown, the second valve body 100 is also included. The second valve body 100 is located on one side of the first valve body 300 and is interconnected. The rotating component 110 is arranged on the second valve body 100, and the second valve body 100 has a driving device 120, which is in transmission connection with the rotating component 110. The second valve body 100 is used to control the switching of the waterway. Specifically, the second valve body 100 controls the switching of the waterway through the driving device 120. When the waterway is switched, the rotating component 110 is driven to rotate. The rotation of the rotating component 110 can make the protrusion 130 rotate accordingly, so as to realize the opening of the corresponding sewage discharge channel 310 while switching the waterway, simplify the control system, and improve the reliability of the control.

[0062] In a specific application, the two protrusions 130 on the rotating component 110 can realize the opening of the sewage discharge channel 310 in the salt absorption position and the backwash position of the soft water valve.

[0063] See also Figure 8As shown, the arrow in the figure represents the flow direction of the waterway. Specifically, the second valve body 100 is connected to the first valve body 300, and the second valve body 100 has a valve core, which is connected to the driving device 120 through the rotating component 110. The valve core has multiple waterway channels, and the multiple waterways can be switched when the driving device 120 is driven. A pressure rod assembly 200 and an ejector 330 are provided in the first valve body 300, and the ejector 330 is connected to the salt box 700 through a pipeline. The lower part of the first valve body 300 is connected to the resin tank 600 through the waterway component 500, and the second valve body 100 is constructed with components that are respectively connected to the first valve body 100, the waterway component 500 and the salt box 700. When the valve core in the second valve body 100 is in the salt absorbing position, a protrusion on the rotating component 110 cooperates with the pressure rod assembly 200 to open the sewage channel 310 and cause the ejector 330 to generate negative pressure to continuously absorb salt. The specific water flow process is as follows: the input raw water is input into the channel with the ejector 330 in the first valve body 300 through the valve core of the second valve body 100. The ejector 330 generates negative pressure so that the saturated salt water in the salt tank 700 is sucked into the channel with the ejector 330. The salt water sucked into the channel is mixed with the raw water and reaches the central tube 610 in the resin tank 600 through the water channel component 500, and rises along the resin filling part through the bottom of the central tube 610. The mixed liquid after rising enters the first valve body 300. At this time, the sewage channel 310 in the first valve body 300 has been opened, and the mixed liquid is discharged through the sewage channel 310. It can be seen that the entire control process can realize the opening of the sewage channel 310 when the second valve body 100 controls the water channel switching. The opening of the sewage channel 310 does not require an independent control system to control, which simplifies the construction of the control system and reduces the difficulty of preparation.

[0064] See also Fig. 9 As shown, the arrow in the figure represents the flow direction of the waterway. When the valve core in the second valve body 100 is in the backwash position, another protrusion on the rotating component 110 cooperates with the pressure rod assembly 200 to open the sewage channel 310. The specific waterway flow process is as follows: the input raw water passes through the valve core of the second valve body 100 and is input into another channel in the first valve body 300. The channel is directly connected to the central tube 610 in the resin tank 600. After passing through the central tube 610, the raw water enters the bottom of the resin tank 600 and rises from the bottom through the resin filling part. Therefore, the sewage channel 310 is opened in this state, and the mixed liquid after rising can be directly discharged through the sewage channel 310.

[0065] It can be understood that in this embodiment, the protrusions 130 in different positions can correspond to multiple functional states that require the sewage channel 310 to be opened. When the valve core in the second valve body 100 is in the corresponding water channel state, the protrusion 130 can cooperate with the pressure rod assembly 200 to realize the opening of the sewage channel 310. The entire process does not require an additional control passage, simplifies the control system, and improves the overall reliability through mechanical transmission opening.

[0066] For specific settings, see Figure 1 , Figure 2 As shown, the rotating component 110 includes a transmission gear, and the driving device 120 has a driving gear, and the driving gear meshes with the transmission gear for transmission. When the second valve body 100 switches the water path, it is necessary to overcome factors such as the resistance of the water body in the valve core. Therefore, a certain torque is usually required to drive the valve core to move. In this embodiment, the gear meshing transmission method can flexibly meet the requirements of different torque sizes by adjusting the transmission ratio.

[0067] For specific applications, see Figure 1 As shown, the ratio of the driving gear to the transmission gear is much larger than 1. This arrangement enables the transmission gear to have a larger torque in a smaller space to drive the valve core and reduce the volume of the overall product.

[0068] According to an embodiment provided by the utility model, see Figure 3 As shown, the protrusion 130 includes an abutment structure, the abutment structure has an arc-shaped abutment surface, the abutment surface has a matching abutment section 1301 in the middle and guide sections 1302 on both sides, and the minimum distance L1 between the guide section 1302 and the end of the pressure rod assembly 200 is greater than the minimum distance L2 between the matching abutment section 1301 and the end of the pressure rod assembly 200. Figure 3 In the figure, the arrow on the transmission gear indicates that when the guide section 1302 rotates a certain angle, that is, the position indicated by the dotted line in the figure, the guide section 1302 is substantially perpendicular to the pressure rod assembly 200, and the minimum distance at this time is L1 in the figure. The abutment section 1301 is the position indicated by the solid line, and the minimum distance between the guide section 1302 and the pressure rod assembly 200 is L2 in the figure. The pressure rod assembly 200 is located on one side of the rotating component 110, that is, the pressure rod assembly 200 is located in the radial direction of the rotating component 110, and when the rotating component 110 rotates, it cooperates with the pressure rod assembly 200 and can achieve the extrusion of the pressure rod assembly 200. In this embodiment, the abutment surface between the protrusion 130 and the pressure rod assembly 200 is set to an arc surface. The setting of the arc surface can improve the service life of the pressure rod assembly 200 and prevent the pressure rod from being gradually damaged due to extrusion during the rotation process.

[0069] It can be understood that the raised portion 130 in this embodiment has a guiding section 1302 and a mating abutment section 1301, and the guiding section 1302 and the mating abutment section 1301 together form an arc-shaped surface. When the rotating portion rotates, the pressure rod assembly 200 first contacts the guiding section 1302 and gradually approaches the mating abutment section 1301 during the rotation process. After reaching the mating abutment section 1301, the pressure rod assembly 200 is completely pressed down, thereby achieving full opening of the sewage discharge channel 310.

[0070] For specific settings, see Figure 3 As shown, the abutment structure of the protrusion 130 is connected to the rotating component 110 through the connecting rib 150, that is, the connecting rib 150 is connected to the transmission gear and strengthens the abutment structure, so that the protrusion 130 has a strong strength and improves its service life. In a specific application, the two protrusions 130 have different specifications, and one of the protrusions 130 has a longer guide section 1302.

[0071] It is understandable that the protrusion 130 and the pressure rod assembly 200 need to withstand a certain force when they are in abutment with each other for a long time. In this embodiment, the protrusion 130 has a stronger structural strength through the setting of the connecting rib 150, thereby making the protrusion 130 have higher stability.

[0072] According to an embodiment provided by the utility model, see Figure 3 As shown, it also includes a positioning portion 140, which is arranged on the rotating component 110, and the positioning portion 140 is arranged at a distance from the protrusion 130, and the positioning portion 140 is used to sense the rotation position of the rotating component 110. When the second valve body 100 switches the waterway, the position of the valve core is the key to controlling the waterway switching. In this embodiment, by setting the positioning portion 140 on the rotating component 110, that is, on the transmission gear, the positioning portion 140 can sense the position when rotating, thereby improving the accuracy of opening the sewage discharge channel 310.

[0073] In the specific setting, the positioning part 140 can be a magnet or other parts. A control board is set below the rotating part 110. A plurality of Hall sensors are set on the control board. Each Hall sensor corresponds to a different water channel. When the rotating part 110 rotates, the positioning part 140 rotates accordingly, so that a sensing signal can be generated between the Hall sensor, thereby realizing the control of the position. For example, there is a Hall sensor corresponding to the salt absorption position on the control board. When the rotating part 110 rotates to the Hall sensor position, a protrusion 130 on the rotating part 110 just abuts against the pressure rod assembly 200 to realize the accurate opening of the sewage discharge channel 310 when the salt absorption position is achieved.

[0074] It can be understood that the entire control system is further simplified by the provision of the positioning portion 140. During control, it is only necessary to control the position of the positioning portion 140 to achieve control over the opening of each channel. Each position of the positioning portion 140 can be mapped to a different waterway position, so that the overall component does not require a complex control system, reducing the difficulty of preparation.

[0075] According to an embodiment provided by the utility model, see Figure 1 , Figure 8 The first valve body 300 also includes a mounting portion 320, which is connected to the sewage channel 310, and has an installation chamber in the mounting portion 320, one end of the installation chamber has an opening, and the inner wall of the installation chamber has a connecting port, which is used to connect the installation chamber with the sewage channel 310; the pressure rod assembly 200 includes a pressure rod body 210, a fixing sleeve 220 and a limiting sleeve 230, one end of the pressure rod body 210 is connected to the limiting disk 240, and the other end of the pressure rod body 210 is connected to the matching head 2101; the fixing sleeve 220 is fixedly arranged at the end of the installation chamber with the opening; the limiting sleeve 230 and The fixing sleeve 220 is connected, and the fixing sleeve 220 and the limiting sleeve 230 are both sleeved on the pressure rod body 210. A spring 250 is sleeved between the limiting plate 240 and the fixing sleeve 220, so that the pressure rod body 210 can be reset under the action of the spring 250; wherein, a connecting port 2301 is opened on the side wall of the limiting sleeve 230, and the connecting port 2301 is communicated with the connecting port, and the end of the limiting sleeve 230 away from the fixing sleeve 220 has a matching port 2302, and the matching port 2302 is communicated with the connecting port 2301, and the matching port 2302 can be matched and sealed with the matching head 2101. The pressure rod assembly 200 needs to cooperate with the sewage discharge channel 310 to realize the opening of the sewage discharge channel 310, see Figure 5 As shown, in this embodiment, a mating head 2101 is provided on one end of the pressure rod body 210, and sealing is achieved through the contact and cooperation between the mating head 2101 and the mating port 2302. When the pressure rod body 210 is squeezed, the mating head 2101 and the mating port 2302 are no longer sealed, and the sewage discharge channel 310 can be opened for sewage discharge operations.

[0076] It is understandable that if Figure 4 , Figure 8 As shown, when the pressure rod assembly 200 is in normal state, the pressure rod body 210 makes the mating head 2101 contact and seal with the mating port 2302 on the limit sleeve 230 due to the action of the spring 250. When the protrusion 130 abuts against the pressure rod body 210, the pressure rod body 210 extends. Figure 5At this time, the mating head 2101 and the mating port 2302 are no longer in contact, and the drain channel 310 is opened. The drain channel 310 is opened and closed by extending and resetting the pressure rod, and the response speed is fast, and the drain channel 310 can be opened and closed in a timely and rapid manner.

[0077] According to an embodiment provided by the utility model, see Figure 2 , Figure 3 As shown, the lever mechanism 400 is also included. The lever mechanism 400 is arranged between the pressure rod assembly 200 and the protrusion 130. The lever mechanism 400 is used to amplify the thrust and transmit the thrust. The protrusion 130 is arranged on the rotating component 110. The rotating component 110 is connected to the valve core to transmit mechanical energy so that the valve core can move. In this embodiment, the service life of the valve system is increased by the arrangement of the lever mechanism 400, and the difficulty and cost of maintenance are reduced.

[0078] It is understandable that the rotating part 110 is connected to the valve core of the second valve body 100, and the way in which the protrusion 130 directly acts on the pressure rod assembly 200 makes the protrusion 130 easily damaged, especially in the case of a long time, this problem is particularly prominent, and once the protrusion 130 is damaged, the rotating part 110 needs to be disassembled, and the disassembly of the rotating part 110 is difficult, and it is easy to cause the valve core part to be damaged during the disassembly process. In this embodiment, by arranging a lever mechanism 400 between the protrusion 130 and the pressure rod assembly 200, the transmission is carried out through the intermediate lever mechanism 400, which greatly avoids the damage of the protrusion 130, prolongs the service life of the protrusion 130, and compared with the disassembly and maintenance of the rotating part 110, the disassembly of the lever mechanism 400 is simpler, and the difficulty and cost of maintenance are lower.

[0079] For specific settings, see Figure 7 As shown, the lever mechanism 400 includes a crank lever 410, one end of which is rotatably arranged, and the other end of which is located between the rotating component 110 and the lever assembly 200. The crank transmits the force to the protrusion 130 through its own rotation, and the rotation of the end of the crank lever 410 amplifies the transmission force, so that the protrusion 130 can squeeze the lever assembly 200 under a relatively small force, thereby opening the sewage discharge channel 310.

[0080] In specific applications, see Figure 7 As shown, the end face where the crank pressure rod 410 contacts the protrusion 130 has a protruding contour, which can cooperate with the protrusion 130 so that the protrusion 130 abuts against the contour during the rotation of the assembly, and finally pushes the pressure rod assembly 200 to open the sewage channel 310.

[0081] It can be understood that for the sake of compact structure and overall layout, the crank pressure rod 410 is rotatably set on the second valve body 100, and the crank pressure rod 410 is located on one side of the rotating part 110, and the entire crank pressure rod 410 is located below the rotating part 110, so that a part of the crank pressure rod 410 can be located below the rotating part 110 to achieve contact with the protrusion 130.

[0082] For specific settings, see Figure 6 , Figure 7 As shown, the crank lever 410 is also configured with a guide slot 4101, and the second valve body 100 is provided with a guide column 160, and the top of the guide column 160 cooperates with the guide slot 4101 for guidance. The guide column 160 has a certain length, and one end thereof is rotatably connected. In this embodiment, the stability of the crank lever 410 can be improved by setting the guide slot 4101 and the guide column 160, thereby making the opening of the entire sewage discharge channel 310 more reliable and stable.

[0083] It is understandable that when in use, the crank pressure rod 410 contacts the protrusion 130 to achieve rotation, which makes it very easy to shake when rotating around one end. In this embodiment, the guide column 160 and the guide groove 4101 are coordinated so that the guide column 160 is used to guide the crank pressure rod 410 during rotation, thereby preventing its shaking and improving the stability of the rotation of the crank pressure rod 410.

[0084] In specific applications, see Figure 7 As shown, the crank pressure rod 410 has a limiting groove 4102 on one end close to the pressure rod assembly 200, and the limiting groove 4102 is used to abut against the pressure rod assembly 200. The abutting end of the pressure rod assembly 200 is a rod-shaped structure, and the rod-shaped structure will have a certain degree of shaking when it contacts the plane. In this embodiment, the limiting groove 4102 is provided on the crank pressure rod 410 to prevent shaking during the abutment process and improve the stability of the overall structure.

[0085] The utility model further provides a water softener, comprising a water channel component 500, a salt box 700 and a sewage system as provided in any one of the above embodiments, wherein the water channel component 500 and the salt box 700 are both connected to the sewage system.

[0086] Through the description of the above embodiments, those skilled in the art can clearly understand that in each embodiment, a protrusion 130 is provided on the rotating member, and the protrusion 130 cooperates with the pressure rod assembly 200, so that the protrusion 130 can realize the squeezing of the pressure rod assembly 200, thereby realizing the opening of the sewage channel 310. The opening of the entire sewage channel 310 is realized by mechanical transmission. The structure of the entire switch is simple, and the reliability and stability are strong.
