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.

[0052] Combine the following Figure 1-Figure 10Describe the control valve of the utility model. It is understandable that the water softener absorbs metal cations such as calcium and magnesium in the raw water through the resin inside it, so as to achieve the purpose of softening water. When the resin adsorbs calcium and magnesium ions to saturation, the resin needs to be regenerated, and the regeneration is to replace the calcium and magnesium ions in the resin with softening salt. The water softener usually needs to realize functions such as water supply, backwashing, salt absorption, slow washing, etc. Its internal waterway is complex and needs to be controlled by a special control valve.

[0053] According to the water softener of the embodiment of the utility model, the control valve 100 is included, and the control valve 100 is used to control the flow direction of water in the water softener to realize the functions of water supply, backwashing, salt absorption, slow washing, etc. The water softener also includes a resin tank and a salt box, wherein the resin tank is filled with resin, and the resin can filter the raw water and adsorb metal ions such as calcium and magnesium in the raw water to reduce the hardness of the water. The salt box is filled with brine, and the salt box is connected with the resin tank to provide brine for the resin tank. The brine is used to clean the resin to replace the calcium and magnesium ions in the resin, so that the resin can continue to adsorb the metal ions in the raw water. The control valve 100 is connected with both the resin tank and the salt box, and the control valve 100 is used to control the flow direction of water. For example, the control valve 100 can control the raw water to enter the resin tank for filtration to provide soft water or rinse the resin; or control the raw water to enter the salt box and dissolve the salt in the salt box to provide brine.

[0054] See also Figure 1 and Figure 3 As shown, the control valve 100 according to the embodiment of the present utility model includes a valve seat 110 , an adjustment assembly 120 , a push rod assembly 130 , a drive motor 140 and a drive gear 150 .

[0055] Specifically, a plurality of water channels are provided in the valve seat 110, and the plurality of water channels can transport water to different positions in the water softener to realize functions such as water supply, backwashing, and slow washing. The regulating component 120 is inserted into the valve seat 110, and one end of the regulating component 120 is located in the valve seat 110, and the other end is located outside the valve seat 110. The regulating component 120 can rotate relative to the valve seat 110 to switch the water channels or control the opening of the water channels. For example, the plurality of water channels include a first water channel, a second water channel, and a third water channel, wherein the first water channel is connected to the resin tank; the second water channel is connected to the salt box; and the third water channel is connected to the water source to provide raw water. The regulating component 120 can adjust the first water channel and the third water channel to open so that the raw water flows into the resin tank for filtration to produce soft water; or, the regulating component 120 can adjust the second water channel and the third water channel to open so that the raw water flows into the salt box to dissolve the salt to form salt water.

[0056] The push rod assembly 130 is disposed on the valve seat 110, and the push rod assembly 130 is used to control the opening of the drain port of the valve seat 110 so as to discharge the sewage generated during the operation of the water softener. For example, during the backwashing and slow washing process, the sewage generated can be discharged through the drain port. Figure 5 As shown, a transmission gear 141 is provided on the output shaft of the driving motor 140, and the transmission gear 141 is meshedly connected with the driving gear 150 to drive the driving gear 150 to rotate. The driving gear 150 is connected with the adjusting component 120 to drive the adjusting component 120 to rotate. When adjusting the opening of the waterway, the driving motor 140 drives the transmission gear 141 to rotate, and the transmission gear 141 drives the driving gear 150 to rotate, and the driving gear 150 drives the adjusting component 120 to rotate a certain angle, thereby adjusting the opening of the corresponding waterway to achieve the corresponding function or adjust the flow of water. In the related art, the transmission structure function of the control valve 100 is relatively single, and a relative transmission structure needs to be set for control according to different waterway control needs, which will make the structure of the control valve 100 redundant, the manufacturing cost is high, and the volume is too large.

[0057] like Figure 4 As shown, a push block 151 is provided on one side of the driving gear 150, and the driving gear 150 can drive the push block 151 to move. When the driving gear 150 rotates to a preset position, the push block 151 is suitable for pushing the push rod assembly 130 to move to adjust the opening of the sewage outlet. For example, when the slow wash function needs to be realized, the driving motor 140 drives the driving gear 150 to rotate to a preset position, and the driving gear 150 drives the adjustment assembly 120 to rotate so that the corresponding waterway is opened, and the push block 151 follows the driving gear 150 to move to the corresponding position, and the push block 151 contacts the push rod assembly 130. As the driving gear 150 rotates, the push block 151 pushes the push rod assembly 130 to move, so that the sewage outlet is opened for sewage discharge.

[0058] According to the driving gear 150 of the embodiment of the utility model, by setting a push block 151 on one side of the driving gear 150, when the driving gear 150 drives the push block 151 to move to a preset position, the push block 151 can push the push rod assembly 130 on the control valve 100 to move, so as to adjust the opening of the sewage outlet. Therefore, the driving gear 150 has the functions of both transmission and adjustment of the opening of the sewage outlet, which is conducive to simplifying the transmission and adjustment structure of the control valve 100, reducing the volume of the control valve 100, and reducing the cost.

[0059] According to the control valve 100 of the embodiment of the utility model, the drive motor 140 drives the adjustment assembly 120 to move to adjust the opening of the waterway, thereby realizing multiple functions; at the same time, the push block 151 on the drive gear 150 can drive the push rod assembly 130 to move to adjust the opening of the sewage outlet. The control of the waterway opening and the sewage outlet opening is realized through a power source and a set of transmission mechanisms (i.e., the transmission gear 141 and the drive gear 150), which simplifies the structure of the control valve 100 and reduces the cost.

[0060] like Figure 7 As shown, a connecting groove 113 is provided in the valve seat 110, and an adjusting component 120 is inserted in the connecting groove 113. One end of the adjusting component 120 is located outside the valve seat 110 and connected to the driving gear 150. The other end of the adjusting component 120 is located in the connecting groove 113 and at the connecting point between the water channel and the connecting groove 113. The opening of the corresponding connecting point between the water channel and the connecting groove 113 is adjusted by rotating the adjusting component 120. Figure 2 and Figure 8 The regulating assembly 120 includes a moving disk 121 and a rotating shaft 122. The moving disk 121 is provided with a flow hole 1213. The moving disk 121 is arranged at the connection point between the connecting groove 113 and the waterway. The flow hole 1213 is connected to the corresponding waterway by rotating the moving disk 121 to control the flow direction of water, thereby achieving different functions. The driving gear 150 is connected to one end of the rotating shaft 122, and the moving disk 121 is connected to the other end of the rotating shaft 122. The driving gear 150 rotates to drive the rotating shaft 122 to rotate, thereby driving the moving disk 121 to rotate.

[0061] like Figure 7As shown, a plurality of water diversion grooves 116 are provided on the bottom wall of the connecting groove 113, and each water diversion groove 116 is connected to a corresponding water channel. For example, the plurality of water channels include a first water channel, a second water channel and a third water channel, and the plurality of water diversion grooves 116 include a first water diversion groove 116, a second water diversion groove 116, a third water diversion groove 116 and a fourth water diversion groove 116. The first water diversion groove 116 is connected to the first water channel, the second water diversion groove 116 is connected to the second water channel, and the third water diversion groove 116 and the fourth water diversion groove 116 are both connected to the third water channel. Among them, the third water channel can be a water inlet pipe 117, and is connected to a water source. The third water diversion groove 116 and the fourth water diversion groove 116 are both connected to the third water channel to increase the flow rate of raw water and quickly supply water. When the circulation hole 1213 is connected to the first water tank 116 and the third water tank 116, raw water flows from the third water channel into the third water tank 116 and the fourth water tank 116, and the raw water in the third water tank 116 and the fourth water tank 116 flows into the connecting tank 113 through the circulation hole 1213, and the raw water in the connecting tank 113 flows to the first water tank 116 through the circulation hole 1213, and finally flows to the first water channel. There can be multiple circulation holes 1213. The first water channel can be an output pipe 118, and is connected to the inlet of the resin tank, so that the raw water is transported to the resin tank through the first water channel for filtration to form soft water, and the soft water flows out from the outlet of the resin tank to be provided to the user. Figure 7 As shown, the valve seat 110 may also be provided with a water outlet pipe 119, which is connected to the resin tank, and soft water may be output through the water outlet pipe 119 and transported to a user terminal, such as a faucet or a water heater, through a pipeline. It should be noted that only one embodiment is provided here for ease of understanding, and the number and corresponding relationship between the water distribution tanks 116 and the water channels are not limited.

[0062] See also Figure 2 As shown, the control valve 100 may also include a fixed plate 114 and a gasket 115, both of which are sandwiched between the moving plate 121 and the bottom wall of the connecting groove 113, wherein the gasket 115 is in contact with the bottom wall of the connecting groove 113, the fixed plate 114 and the gasket 115 are stacked, and the fixed plate 114 is sandwiched between the gasket 115 and the moving plate 121, and the gasket 115 may be a rubber part, and the gasket 115 is deformed to make the fixed plate and the bottom wall of the connecting groove 113 sealed to avoid water leakage. A plurality of through holes are provided on the fixed plate 114 and the gasket 115, and the positions and shapes of the through holes on the fixed plate 114 and the gasket 115 correspond to the positions and shapes of the water dividing groove 116.

[0063] like Figure 8As shown, a connection disk 124 is provided at one end of the rotating shaft 122, and the connection disk 124 is fixedly connected to the movable disk 121. A limit block 125 and a limit notch 126 are provided on the connection disk 124, and a matching groove 1211 and a matching protrusion 1212 are provided on the movable disk 121. The limit block 125 is suitable for being embedded in the matching groove 1211, and the matching protrusion 1212 is suitable for being embedded in the limit notch 126, so as to limit the movable disk 121 circumferentially, so that the movable disk 121 and the rotating shaft 122 rotate synchronously, and the rotating shaft 122 and the movable disk 121 are convenient for installation and removal. Figure 2 As shown, the control valve 100 also includes a gland 111, which is covered on the valve seat 110 and connected to the valve seat 110, and the rotating shaft 122 is passed through the gland 111. A plurality of first sealing rings 1112 are sleeved on the outer circumferential surface of the rotating shaft 122 to seal the connection between the rotating shaft 122 and the gland 111.

[0064] like Fig. 9 and Fig.10 As shown, a pressure block 1111 is provided on one side of the pressure cover 111. The pressure block 1111 is embedded in the connecting groove 113 and abuts against the connecting disk 124 to limit the rotation shaft 122 in the axial direction, so that the moving disk 121 and the fixed disk 114 fit tightly to avoid water leakage between the water channels. Figure 2 As shown, in some embodiments, the control valve 100 further includes a second sealing ring 1113, which is sandwiched between the pressing block 1111 and the inner wall of the connecting groove 113 to seal the connecting groove 113. Fig. 9 As shown, a plurality of receiving grooves 1116 are provided on one side where the pressing block 1111 and the connecting disk 124 abut against each other. The receiving grooves 1116 are used to receive water between the pressing block 1111 and the connecting disk 124 so as to make the pressing block 1111 and the connecting disk 124 fit together.

[0065] like Figure 7 and Fig. 9 As shown, the valve seat 110 is provided with a mounting groove 1101, and the mounting groove 1101 is used to receive the drive motor 140. Part of the structure of the gland 111 is covered on the mounting groove 1101. The gland 111 is provided with a mounting plate 1114, which protrudes from the side of the gland 111 away from the valve seat 110, and the mounting plate 1114 is suitable for abutting against one end of the drive motor 140. The mounting plate 1114 and the drive motor 140 can be fixedly connected by screws. The mounting plate 1114 is provided with an axial hole 1115, and the output shaft of the drive motor 140 is passed through the axial hole 1115 to be connected with the transmission gear 141.

[0066] See also Figure 4As shown, according to some embodiments of the utility model, the push block 151 is disposed on one side end surface of the driving gear 150, and the push block 151 includes an arc plate 1511, and the arc plate 1511 is suitable for contacting the push rod assembly 130 to push the push rod to move. The push rod assembly 130 is retractable. After the push rod assembly 130 contacts the arc plate 1511, as the driving gear 150 rotates, the arc plate 1511 squeezes the push rod assembly 130 so that the push rod assembly 130 is compressed to adjust the opening of the sewage outlet.

[0067] like Figure 1 and Figure 4 As shown, the length direction of the push rod assembly 130 is perpendicular to the central axis of the driving gear 150, and the push rod assembly 130 is retractable in its length direction. The arc plate 1511 extends along the circumference of the driving gear 150, and one side of the arc plate 1511 faces the direction of the push rod assembly 130. There are at least two places on the arc plate 1511 that are different from the central axis of the driving gear 150. For example, the distance between one end of the arc plate 1511 and the central axis of the driving gear 150 is smaller than the distance between the other end and the central axis of the driving gear 150. The arc plate 1511 contacts and compresses the push rod assembly 130. As the driving gear 150 rotates, the push rod assembly 130 moves along the surface of one side of the arc plate 1511. When the push rod assembly 130 moves to the farthest point on the arc plate 1511 from the central axis of the driving gear 150, the compression amount of the push rod assembly 130 is the largest, and the opening of the sewage outlet is the largest.

[0068] like Figure 3 As shown, in some embodiments, the control valve 100 further includes a lever 131, which is swingably connected to the valve seat 110, and is located between the push rod assembly 130 and the push block 151, and a slideway is provided on one side of the lever 131. One end of the push rod assembly 130 contacts the slideway and can slide along the slideway. When the driving gear 150 rotates to a preset position, the arc plate of the push block 151 contacts one side of the lever 131 and pushes the lever 131 to swing, and the lever 131 pushes the push rod assembly 130 to move. In this process, one end of the push rod assembly 130 slides along the slideway, reducing the contact impact force between the end of the push rod assembly 130 and the push block 151, so that the movement of the push rod assembly 130 and the driving gear 150 is smoother.

[0069] See also Figure 4 As shown, according to some embodiments of the present invention, the arc plate 1511 includes a first section 1512 and a second section 1513, the curvature of the first section 1512 is smaller than the curvature of the second section 1513, and the first section 1512 is flatter than the second section 1513. Figure 1As shown, the first section 1512 and the second section 1513 are both arc-shaped, the radius R1 of the circle corresponding to the first section 1512 is greater than the radius R2 of the circle corresponding to the second section 1513 , and the curvature of the first section 1512 is less than the curvature of the second section 1513 .

[0070] In the rotation direction of the driving gear 150, the first section 1512 is located in front of the second section 1513. Figure 1 As shown, the driving gear 150 rotates in a clockwise direction (as shown in FIG. Figure 1 The driving gear 150 drives the push block 151 to move, and the first section 1512 is located in front of the second section 1513, so that the push rod assembly 130 first contacts the first section 1512 and then contacts the second section 1513. The point on the push block 151 that is farthest from the central axis of the driving gear 150 is located on the second section 1513. In this way, the first section 1512 can play a guiding role, so that the contact process between the push rod assembly 130 and the arc plate 1511 is smoother. During operation, the driving motor 140 drives the driving gear 150 to rotate, and the push block 151 follows the driving gear 150 to move so that the first section 1512 contacts the push rod assembly 130. Afterwards, as the driving gear 150 continues to rotate to a preset position, the push rod assembly 130 moves along the first section 1512 to the second section 1513. When the driving gear 150 moves to the preset position, the push rod assembly 130 moves to the position on the push block 151 that is farthest from the central axis of the driving gear 150. At this time, the compression amount of the adjustment assembly 120 is the largest and the opening of the sewage outlet is the largest.

[0071] See also Figure 4 As shown, according to some embodiments of the present invention, the push block 151 further includes a reinforcing column 1514 and a first reinforcing rib 1515, one end of the first reinforcing rib 1515 is connected to the reinforcing column 1514, and the other end of the first reinforcing rib 1515 is connected to the arc plate 1511, thereby improving the strength of the push block 151. There can be multiple first reinforcing ribs 1515, and the multiple first reinforcing ribs 1515 are distributed along the extension direction of the arc plate 1511, wherein at least two first reinforcing ribs 1515 are connected to the ends of the arc plate 1511.

[0072] like Figure 4 As shown, in some embodiments, there are two push blocks 151, and the two push blocks 151 are spaced apart along the circumference of the driving gear 150, so that the driving gear 150 has two preset positions during the rotation process. At the two preset positions, the corresponding push blocks 151 push the push rod assembly 130 to move to open the sewage outlet for sewage discharge. Figure 4 In the example, the center of each push block 151 takes the perpendicular line to the central axis of the driving gear 150 as a reference line, and the angle between the two reference lines is 120 degrees, that is, the positions of the two push blocks 151 are 120 degrees apart.

[0073] For example, the multiple water channels in the valve seat 110 include a salt water absorption channel and a backwash water channel. When the water softener is in the salt absorption state, the salt water in the salt tank is sucked into the resin tank, the salt water absorption channel is opened, and raw water is provided through the salt water absorption channel, so that the raw water and the salt water are mixed to clean the resin in the resin tank. At this time, the driving gear 150 moves to one of the preset positions, and one of the push blocks 151 pushes the push rod assembly 130 to open the sewage outlet, thereby discharging the sewage generated by cleaning the resin.

[0074] When the water softener is in the backwash state, the backwash water channel is opened to transport raw water into the resin tank, and the raw water cleans the resin in the resin tank, so that the broken resin is washed away and the distance between the resins is increased, so that when the resin filters the raw water, the raw water and the resin are fully in contact, thereby improving the adsorption capacity of calcium and magnesium ions. At this time, the driving gear 150 moves to another preset position, and another push block 151 on the driving gear 150 pushes the push rod assembly 130 to move, so as to open the sewage outlet, so that the sewage generated in the tree cleaning process can be discharged.

[0075] like Figure 2 As shown, according to some embodiments of the present invention, the transmission ratio of the transmission gear 141 and the driving gear 150 is greater than 1, that is, the number of teeth of the driving gear 150 is greater than the number of teeth of the transmission gear 141. The transmission gear 141 and the driving gear 150 can amplify the driving torque to resist the pressure of water on the moving disc 121 and provide sufficient power to drive the adjustment assembly 120 to rotate. Figure 2 and Figure 3 As shown, in some embodiments, a second reinforcing rib 152 is provided on at least one side end surface of the driving gear 150 , and the second reinforcing rib 152 extends radially along the driving gear 150 . There may be a plurality of second reinforcing ribs 152 , thereby improving the strength of the driving gear 150 .

[0076] According to some embodiments of the utility model, the control valve 100 further includes a Hall sensor 161, a magnetic member 157 is provided on the driving gear 150, and the magnetic member 157 rotates with the driving gear 150. The Hall sensor 161 is used to detect the position of the magnetic member 157, thereby controlling the driving motor 140 to rotate according to the position of the detected magnetic member 157, so that the driving gear 150 drives the adjusting assembly 120 to rotate to the corresponding position, so that the corresponding water channel is connected and the corresponding function is realized. For example, when soft water needs to be provided, according to the position of the magnetic member 157 detected by the Hall sensor 161, the driving motor 140 is controlled to rotate, the driving gear 150 rotates and drives the magnetic member 157, and the driving gear 150 drives the adjusting assembly 120 to rotate. When it is detected that the magnetic member 157 is located at the specified position, the driving motor 140 stops rotating, and the flow hole 1213 on the moving disk 121 is connected with the corresponding water channel, so that the raw water can be transported to the resin tank through the corresponding water channel for filtration to form soft water, and provided to the user for use.

[0077] like Figure 2 and Figure 5 As shown, according to some embodiments of the present invention, the control valve 100 also includes a positioning plate 160, and a plurality of screw holes 162 are provided on the positioning plate 160, and the plurality of screw holes 162 are not on the same straight line, and the screws are passed through the screw holes 162 and connected to the valve seat 110 to fix the positioning plate 160. The Hall sensor 161 is provided on the positioning plate 160, and the positioning plate 160 and the driving gear 150 are stacked. The positioning plate 160 can be provided between the driving gear 150 and the pressure cover 111, and an avoidance hole 163 is provided on the positioning plate 160, and the rotating shaft 122 is passed through the avoidance hole 163. The magnetic part 157 is located on the end face of the driving gear 150 facing the positioning plate 160, so as to improve the accuracy of the Hall sensor 161 in detecting the position of the magnetic part 157. As shown Figure 1 and Figure 4 As shown, the magnetic member 157 and the push block 151 are both disposed on the end surface of the driving gear 150 facing the positioning plate 160, the driving gear 150 and the positioning plate 160 are spaced apart, and one end of the push rod assembly 130 extends between the driving gear 150 and the positioning plate 160 to contact the push block 151. Figure 4 As shown, a mounting post 156 is provided on the end surface of the driving gear 150 facing the positioning plate 160 , and a magnetic member 157 is embedded in the mounting post 156 to reduce the distance between the magnetic member 157 and the positioning plate 160 , thereby improving the accuracy of position detection of the magnetic member 157 .

[0078] like Figure 6As shown, in some embodiments, there are multiple Hall sensors 161, and the multiple Hall sensors 161 are distributed along the movement path of the magnetic member 157, that is, the Hall sensors 161 are located on the positive projection of the movement path of the magnetic member 157 on the positioning plate 160. In this way, the accuracy of the position detection and positioning of the magnetic member 157 can be improved. The position of each Hall sensor 161 corresponds to a function of the water softener. When the magnetic member 157 moves to the position relative to the Hall sensor 161 of the corresponding function, the corresponding water channel is opened to transport water to the corresponding position. For example, the position of one of the multiple Hall sensors 161 corresponds to the function of providing soft water. When the magnetic member 157 moves to the position relative to the Hall sensor 161, that is, the positive projection of the magnetic member 157 on the positioning plate 160 falls on the Hall sensor 161, the flow hole 1213 on the moving disk 121 is connected to the corresponding water channel, so that the raw water is transported to the resin tank for filtration to obtain soft water for supply to the user.

[0079] See also Figure 4 As shown, according to some embodiments of the present invention, a limiting column 153 is provided on one end surface of the driving gear 150, and the cross section of the limiting column 153 is polygonal. One end of the adjustment component 120 is provided with a mounting hole, and the mounting hole is adapted to the limiting column 153, so as to perform circumferential positioning on the driving gear 150. Figure 4 As shown, in some embodiments, the limiting column 153 includes a main body and a positioning portion 154, and the positioning portion 154 protrudes radially from the outer wall of the main body of the limiting column 153, so that the cross section of the limiting column 153 is irregularly shaped. Figure 4 In the example, the cross section of the limiting column 153 is an irregular shape formed by a combination of a hexagon and a rectangle. A positioning groove is provided on the inner wall of the mounting hole, and the positioning portion 154 is embedded in the positioning groove, so as to position the matching position of the driving gear 150 and the adjusting assembly 120 in the circumferential direction, avoid the misalignment of the driving gear 150 and the adjusting assembly 120 during the assembly process, and save the debugging steps. The limiting column 153 can be provided with a through hole, the mounting hole is a blind hole, and a threaded hole is provided on the bottom wall of the mounting hole. The connecting screw 158 is passed through the through hole and the threaded hole to axially limit the driving gear 150.

[0080] See also Figure 4As shown, according to some embodiments of the utility model, a limiting rib 155 is further provided on one end surface of the driving gear 150. The limiting rib 155 extends around the limiting column 153, and the limiting rib 155 is annular. A limiting groove is defined between the limiting rib 155 and the limiting column 153. The end of the adjustment component 120 is inserted into the limiting groove to limit the adjustment component 120, so that the adjustment component 120 is firmly connected to the driving gear 150. Specifically, the rotating shaft 122 of the adjustment component 120 is inserted into the limiting groove, and a mounting hole is provided on one end surface of the rotating shaft 122, and the limiting column 153 is inserted into the mounting hole. The outer diameter of the rotating shaft 122 is slightly larger than the inner diameter of the limiting rib 155, so that the rotating shaft 122 is firmly connected to the driving gear 150.

[0081] See also Figure 2 As shown, in some embodiments, the soft water control valve 100 further includes a cover 112, which is disposed on the valve seat 110 and connected to the valve seat 110. For example, the cover 112 and the valve seat 110 can be detachably connected by screws. The transmission gear 141, the driving gear 150 and the positioning plate 160 are all located between the valve seat 110 and the cover 112, and the cover 112 plays a role of sealing and protection.
