Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and more specifically, to a soft water valve drive mechanism and a soft water valve. Background Technology

[0002] A water softener uses resin to exchange calcium and magnesium ions in the water, reducing water hardness and thus softening the water. The core component of a water softener is the softening valve, whose main function is to switch between different water paths, such as operation, backwashing, and brine flushing / regeneration. Typically, a motor drives the valve core to rotate to the position corresponding to each operating condition, thereby switching the water path. Current softening valves usually have a single valve core. If multiple valve cores are used, multiple drive systems are required, resulting in larger control components and a more complex control process. Utility Model Content

[0003] The purpose of this utility model is to provide a soft water valve drive mechanism and a soft water valve to solve the problem that existing soft water valves require multiple drive systems when multiple valve cores are installed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A soft water valve drive mechanism includes:

[0006] Drive components;

[0007] A rotating assembly includes an eccentric turntable and a rotating sleeve. The driving component drives the eccentric turntable to rotate through a transmission assembly. The rotating sleeve is sleeved outside the eccentric turntable and is driven by the eccentric turntable to perform linear motion.

[0008] A fixing element is used to install the valve core, and the fixing element is connected to the rotating sleeve.

[0009] In one embodiment, the fixing member includes a connecting rod and a fixing plate. One end of the connecting rod is fixedly connected to the rotating sleeve, and the other end is connected to the fixing plate. The fixing plate is provided with mounting holes for installing the valve core.

[0010] In one embodiment, the system further includes a turntable and a light sensor. The turntable is connected to the rotation shaft of the eccentric turntable. The turntable is provided with a plurality of baffles, which pass sequentially through the light sensor as the turntable rotates.

[0011] In one embodiment, a plurality of the baffles are circumferentially distributed on the turntable.

[0012] In one embodiment, the induction turntable is further provided with an arc-shaped baffle, the light sensor includes a first light sensor and a second light sensor, the baffle can pass through the first light sensor, the arc-shaped baffle can pass through the second light sensor, and the direction of the distribution of the plurality of baffles is consistent with the arc direction of the arc-shaped baffle.

[0013] In one embodiment, a housing is also included, the transmission assembly and the rotating assembly are disposed within the housing, and the fixing member passes through the housing and is connected to the rotating sleeve.

[0014] In one embodiment, the turntable is located outside the housing, and the outer wall of the housing is provided with a slot, in which the light sensor is installed.

[0015] In one embodiment, the transmission assembly includes a driving gear and a driven gear, the driving gear being connected to the output shaft of the drive component, the driven gear meshing with the driving gear, and the rotation shaft of the eccentric turntable being fixedly connected to the driven gear.

[0016] A soft water valve includes a valve body, a valve core, and the aforementioned soft water valve drive mechanism. The valve body has a channel, and the valve core is movably located within the channel. The drive mechanism is used to drive the valve core to reciprocate.

[0017] In one embodiment, the valve body is provided with a guide post, the fixing member is provided with a through hole, the guide post is slidably connected to the fixing member through the through hole, and when the driving mechanism drives the valve core to move, the fixing member slides along the guide post.

[0018] Compared with existing technologies, the advantages of the soft water valve drive mechanism of this invention are as follows: In this soft water valve drive mechanism, the drive component drives an eccentric turntable to rotate via a transmission assembly. The eccentric turntable causes a rotating sleeve to move linearly, which in turn drives a fixed component to move linearly. A valve core is mounted on the fixed component, thus the drive component's movement drives the valve core to reciprocate. Through the combination of the transmission sleeve and the fixed component, the drive component can drive multiple filter elements to move synchronously, eliminating the need for multiple drive systems, greatly simplifying the control components of the soft water valve, and also making the soft water valve smaller.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] It should be noted that the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. The terms "connected" and "linked" should be interpreted broadly, for example, they can refer to fixed connections, detachable connections, or integral connections.

[0029] This utility model embodiment provides a soft water valve drive mechanism, which is used to drive the valve core on the soft water valve to move, so as to realize the switching of multiple functional modes of the soft water machine such as operation, backwashing, brine suction, and water injection.

[0030] like Figure 1 and 2 As shown, the soft water valve in this embodiment includes a valve body 100, a drive mechanism 200, and a valve core 300. The valve body 100 has a channel 11, and the valve core 300 is movably disposed within the channel 11. In this embodiment, multiple valve cores 300 are provided, each movably disposed within the channel 11. The drive mechanism 200 is connected to the multiple valve cores 300 to drive the multiple valve cores 300 to move relative to the valve body 100, thereby switching the water path in the channel 11 and placing the soft water valve in different functional modes.

[0031] like Figure 2-5 As shown, in this embodiment, the drive mechanism 200 includes a drive component 21, a rotating assembly 22, a transmission assembly 23, and a fixing member 24. The rotating assembly 22 includes an eccentric turntable 221 and a rotating sleeve 222. The drive component 21 drives the eccentric turntable 221 to rotate through the transmission assembly 22. The rotating sleeve 222 is fitted outside the eccentric turntable 221, causing the rotating sleeve 222 to be driven by the eccentric turntable 221 to move linearly. The fixing member 24 is connected to the rotating sleeve 222, and the valve core 300 is mounted on the fixing member 24. The movement of the rotating sleeve 222 drives the fixing member 24 to move, thereby causing the valve core 300 to reciprocate linearly relative to the valve body 100, thus realizing the opening and closing of the control channel 11. Multiple valve cores 300 can be installed on the fixing member 24 as needed, so that only one drive system is needed to drive multiple valve cores 300, simplifying the control components of the entire soft water valve and making the soft water valve smaller.

[0032] Furthermore, such as Figure 2 As shown, the valve body 100 is provided with a guide post 12, and the fixing member 24 is provided with a through hole 241. The guide post 12 is slidably connected to the fixing member 24 through the through hole 241. When the drive mechanism 200 drives the valve core 300 to move, the fixing member 24 slides along the guide post 12. The guide post 12 plays a guiding and limiting role in the movement of the fixing member 24, preventing the valve core 300 from shaking during the movement and improving the stability of the entire soft water valve.

[0033] Specifically, the fixing component 24 includes a connecting rod 241 and a fixing plate 242. One end of the connecting rod 241 is fixedly connected to the rotating sleeve 222, and the other end is connected to the fixing plate 242, thereby enabling the fixing plate 242 and the rotating sleeve 222 to move synchronously. With this design, the installation position of the drive component 21 is not restricted; only the relative positions of the connecting rod 241 and the fixing plate 242 need to be adjusted according to the shape of the valve body 100 and the design of the channel 11. The fixing plate 241 has mounting holes for installing the valve core 300. The valve core 300 is secured to the fixing plate 241 through these mounting holes, and the number of mounting holes matches the number of valve cores 300. Correspondingly, through holes 2421 are also provided on the fixing plate 242, and the guide post 12 is arranged parallel to the valve core 300. This ensures that when there are multiple valve cores 300, the movement of the fixing plate 242 is smooth and less prone to shaking. In this embodiment, the number of connecting rods 241 is set according to the number of valve cores 300. When there are a large number of valve cores 300, the corresponding number of connecting rods 241 can be set to two or more to enhance the connection between the fixed plate 242 and the rotating sleeve 222.

[0034] In this embodiment, the transmission assembly 23 includes a driving gear 231 and a driven gear 232. The driving gear 231 is connected to the output shaft of the drive component 21, and the driven gear 232 meshes with the driving gear 231. The rotation shaft of the eccentric turntable 221 is fixedly connected to the driven gear 232, thereby causing the drive component 21 to drive the eccentric turntable 221 to rotate. The meshing transmission between the driving gear 231 and the driven gear 232 can provide a stable transmission ratio and transmission efficiency.

[0035] like Figure 3-6 As shown, the drive mechanism 200 also includes a turntable 25 and a light sensor 26. The turntable 25 is connected to the rotation shaft 2211 of the eccentric turntable 221. The turntable 25 is provided with several baffles 251. When the turntable 25 rotates, the baffles 251 pass through the light sensor 26 in sequence. The light sensor 26 scans the baffles 251 that pass through and obtains the rotation angle of the turntable 25 by the number of pulses. Then, it obtains the displacement of the rotating sleeve 222 and finally the displacement of the valve core 300. Then, it obtains the position of the valve core 300 in the channel 11, thereby realizing the switching of different functional modes of the soft water valve.

[0036] Specifically, such as Figure 5-6 As shown, several baffles 251 are circumferentially distributed on the turntable 25, allowing each baffle 251 to pass sequentially through the light sensor 26. In this embodiment, the number of baffles 251 is set according to the functional requirements of the soft water valve. For example, if the soft water valve has four functional modes—operation, backwashing, salt absorption and regeneration, and water replenishment—then at least four baffles 251 are provided.

[0037] More specifically, the turntable 25 is also equipped with an arc-shaped baffle 252. The light sensor 26 includes a first light sensor 261 and a second light sensor 262. The arc-shaped baffle 252 is concentric with the turntable 25. Several baffles 251 can pass through the first light sensor 261, and the arc-shaped baffle 252 can pass through the second light sensor 262. The distribution direction of the baffles 251 is consistent with the arc direction of the arc-shaped baffle 252. When some of the baffles 251 pass through the first light sensor 261 in sequence, the arc-shaped baffle 262 always remains in the state of passing through the second light sensor 262. In this embodiment, the two ends of the arc-shaped baffle 252 are not on the same radius as the nearest baffle 251. For example, when four baffles 251 are provided, the first baffle corresponds to the soft water valve in the operating mode, and the fourth baffle 251 corresponds to the soft water valve in the water filling mode. The first end of the arc-shaped baffle 252 is located between the first and second baffles, and the second end of the arc-shaped baffle 252 is located between the fourth and first baffles. When the first light sensor 261 scans the first baffle but the second light sensor 262 does not scan the arc-shaped baffle 252, the soft water valve is in the operating mode. When the first light sensor 261 scans all four baffles in sequence and the second light sensor 262 scans the arc-shaped baffle 252, the soft water valve switches to the water filling mode. Thus, through the cooperation of the first light sensor 261 and the second light sensor 262, the movement displacement and direction of the valve core 300 can be more accurately identified and controlled.

[0038] Furthermore, in this embodiment, the drive mechanism 200 also includes a housing 27, which includes an upper housing 271 and a lower housing 272. The upper housing 271 and the lower housing 272 are fastened together to form the entire housing 27. The transmission assembly 23 and the rotating assembly 22 are disposed inside the housing 27. The housing 27 protects the transmission assembly 23 and the rotating assembly 22. The fixing member 24 passes through the housing 27 and is connected to the rotating sleeve 222. Specifically, the housing 27 may have a through hole for the connecting rod 241 to pass through. The fixing plate 242 is located outside the housing 27. The housing 27 limits the movement of the connecting rod 241 in the longitudinal direction. The turntable 25 is located outside the upper housing 271. The rotating shaft 2211 of the eccentric turntable 221 partially protrudes from the upper housing 271. The insertion slot 253 on the turntable 25 is inserted into the rotating shaft 2211, so that the turntable 25 is fixed on the driven gear 232 and rotates with the driven gear 232. The outer wall of the upper shell 271 is provided with a slot 273, and the light sensor 26 is installed in the slot 273, making it easier to install the light sensor 26.

[0039] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. The protection scope of this utility model patent should be determined by the appended claims.
