Technical Field

[0001] The utility model relates to the field of water purifiers, in particular to a water purifier pipeline switching valve and a self-replacing core direct drinking machine system comprising the same. Background Art

[0002] For a water purifier, the filter element is the most important filter element. As a device that integrates filtering and purification functions, it is designed to effectively filter and separate impurities in the water to achieve the effect of purifying the original water quality. In the daily maintenance of the water purifier, the life status of the filter element is a crucial link, but the primary filter elements of most current water purifiers usually need to be replaced every 3-6 months, and the protected core filter module has a lifespan of up to 1-2 years. In order to replace the relatively cheap primary filter element in a timely manner and extend the life of the relatively expensive core filter module as much as possible, operation and maintenance personnel usually have to visit and replace it every 3-6 months. On the one hand, this greatly increases labor costs, and on the other hand, it also brings a bad experience to users, blocking some users who are afraid of trouble. Utility Model Content

[0003] In order to overcome the increased replacement frequency caused by the different service lives of the filter element groups of the water purifiers in the prior art, the utility model provides a water purifier pipeline switching valve and a self-replacing filter direct drinking machine system including the same. By arranging multiple groups of filter elements with relatively low service lives on the water outlet pipeline, when the service life of a certain filter element has expired or the purification effect is significantly weakened, the valve core is then swung to align the flow hole with other water outlet pipelines, and the water flows out from the other water outlet pipelines and is filtered by the filter elements on the other water outlet pipelines, thereby realizing automatic switching of the filter elements and reducing the replacement frequency of the filter elements.

[0004] The utility model adopts the following technical solutions.

[0008] Preferably, a limit motor is fixedly installed above the valve seat, a movable end of the limit motor is fixedly connected to the valve core, and the limit motor causes the flow hole of the valve core to swing between the first water outlet hole and the second water outlet hole.

[0009] Preferably, the surface of the valve core is covered with sealing rubber, and O-rings are provided between the upper and lower ends of the valve core and the valve seat.

[0015] The utility model provides a water purifier pipeline switching valve and a self-replacing direct drinking machine system including the same. It has the advantage of flexible waterway switching. The swing of the valve core can accurately control the opening and closing of each water outlet, and each water outlet is connected to a primary filter element. At the same time, the structural design is relatively simple. Only basic components such as the valve seat, valve core and flow hole are required to realize complex waterway control functions, and the structure is compact. During use, by controlling the swing direction and angle of the valve core, different waterways can be easily switched, and the operation is simple. The cooperation between the valve core and the valve seat can ensure good sealing performance and prevent water leakage, thereby ensuring that water will not flow out of two water outlets at the same time during the filter element switching process, and avoiding the preset filter element from being filled with water in advance and affecting the use effect. For users, the automatic switching of the primary filter element avoids the shortening of the life of the more expensive post-filter element due to the deterioration of the water quality of the primary filtered water; for merchants, the relay operation of two sets of primary filter elements effectively extends the replacement time of the shortest-lived filter element, which can effectively reduce the frequency of on-site maintenance of the equipment and reduce the subsequent operation and maintenance costs.

[0022] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. In order to better illustrate this embodiment, certain components of the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent the actual size of the product.

[0023] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0024] As attached Figure 1-2 The water purifier pipeline switching valve shown includes a valve seat 1, which is provided with a water inlet hole 2, a first water outlet hole 31 and a second water outlet hole 32. A valve core 4 is swingably provided in the valve seat 1, and the valve core 4 is provided with a flow hole 41.

[0025] When the flow hole 41 is aligned with the first water outlet hole 31, the aligned first water outlet hole 31 is in a conducting state and the second water outlet hole 32 is in a closed state. When the flow hole 41 is aligned with the second water outlet hole 32, the aligned second water outlet hole 32 is in a conducting state and the first water outlet hole 31 is in a closed state. By swinging the valve core 4, switching between the first water outlet hole 31 and the second water outlet hole 32 can be achieved, thereby controlling the direction of the water flow. This design allows one valve to control multiple water outlet pipes, simplifying the piping system. Since one valve can replace multiple separate valves, the installation space and material costs are reduced, so that the switching valve can be installed in a compact space inside the water purifier. When it is necessary to switch between the first water outlet hole 31 and the second water outlet hole 32, the water flow can be switched by simply swinging the valve core 4 manually, mechanically or electrically, which is convenient and quick to operate.

[0026] In some embodiments, a limit motor 5 is fixedly installed above the valve seat 1, and the movable end of the limit motor 5 is fixedly connected to the valve core 4. The limit motor 5 causes the flow hole 41 of the valve core 4 to swing between multiple water outlet holes 3. Through the application of the limit motor 5, automatic control of the valve core 4 can be achieved. Compared with manual operation, automatic control is more accurate and efficient. The limit motor 5 can quickly and accurately switch the position of the valve core 4, thereby quickly changing the direction of water flow, improving the response speed and work efficiency of the system. Furthermore, automatic control reduces the errors of human operation, ensures that each switch can be accurately placed, and improves the reliability of the system. The limit motor 5 can also be combined with an electronic control system to achieve remote control and monitoring, further improving the intelligence level of the system.

[0027] In some embodiments, the surface of the valve core 4 is covered with a sealing rubber 42, and an O-ring 43 is also provided between the upper and lower ends of the valve core 4 and the valve seat 1. The application of the sealing rubber 42 greatly improves the sealing effect between the valve core 4 and the valve seat 1, preventing water from leaking from the water outlet 3 that is not aligned, and ensuring the reliability and safety of the system. The sealing rubber 42 has good elasticity and wear resistance, can reduce the direct friction between the valve core 4 and the valve seat 1, and extend the service life of the valve. At the same time, the sealing rubber 42 can buffer the collision between the valve core 4 and the valve seat 1, reduce the noise generated during operation, and improve the user experience. In addition, the sealing rubber 42 can adapt to different water pressure and temperature changes, maintain good sealing performance, and is suitable for various complex working environments.

[0028] The utility model also includes a self-replacing core direct drinking machine system, which includes the water purifier pipeline switching valve as described above.

[0029] It also includes a pretreatment device, a replacement monitoring device, a reverse osmosis device and a water treatment device that are connected in sequence. The pretreatment device includes a first filter component 61 and a second filter component 62. The first filter component 61 is connected to the first water outlet hole 31 of the water purifier pipeline switching valve, and the second filter component 62 is connected to the second water outlet hole 32 of the water purifier pipeline switching valve.

[0030] In some embodiments, the replacement monitoring device includes a control circuit board 65 and a flow sensor 64. The flow sensor 64 is disposed between the pretreatment device and the reverse osmosis device. The control circuit board 65 is electrically connected to the water purifier pipeline switching valve.

[0031] In some embodiments, the first filter assembly 61 and the second filter assembly 62 both include a coarse-mesh PP cotton filter element, a pre-activated carbon filter element, and a fine-mesh PP cotton filter element. The coarse-mesh PP cotton filter element and the fine-mesh PP cotton filter element are used to remove large particles and suspended solids in the water; the pre-activated carbon filter element is used to further absorb residual chlorine, odor, and organic matter in the water.

[0032] Example 1:

[0033] See also Figure 1 、 Figure 2 and Figure 3 This embodiment demonstrates the specific usage process of the utility model, including a first filter component 61, a second filter component 62, a one-way valve 63, a flow sensor 64, a control circuit board 65, a booster pump 66, an RO reverse osmosis membrane 67, a first solenoid valve 681, a second solenoid valve 682; post-activated carbon 69, and a water outlet tap 7.

[0034] During assembly, first assemble the water purifier pipeline switching valve, insert the O-ring 43 into the valve core 4 and then embed it into the valve seat 1, then tighten the valve cover 11, and interference fit the motor shaft of the limit motor 5 with the valve core 4 to complete the assembly of the water purifier pipeline switching valve.

[0035] The water outlet 3 of the water purifier's pipeline switching valve connects to the first and second filter assemblies 61 and 62, each of which includes a coarse-mesh PP cotton filter element, a pre-activated carbon filter element, and a fine-mesh PP cotton filter element. The water outlet 3 of the water purifier's pipeline switching valve switches between connecting to the first and second filter assemblies 61 and 62. A flow sensor 64 is connected to the check valve 63 to detect the water flow rate. A booster pump 66 is connected to an RO reverse osmosis membrane 67 to provide the required filtration pressure. The RO reverse osmosis membrane 67 is connected to a first solenoid valve 681 and a post-activated carbon filter 69. The post-activated carbon filter 69 is then connected to a second solenoid valve 682 and a water tap 7. The control lines of the control circuit board 65 are connected to the water purifier's pipeline switching valve, booster pump 66, first solenoid valve 681, and second solenoid valve 682, respectively.

[0036] During actual use, the water purifier triggers the valve core 4 controlled by the limit motor 5 according to the detection value of the flow sensor 64 of the primary filter element or the service life of 6 months to switch the water outlet to the second filter component 62 for relay operation. The specific switching process is as follows: the valve core 4 of the water purifier pipeline switching valve rotates clockwise to cut off the water outlet 31, and connects the water outlet 32 pipeline to complete the filter element switching. After the filter element switching is completed, the control circuit board 65 marks the used filter element as scrapped, and at the same time starts the booster pump 66, opens the first solenoid valve 681 to start flushing the new primary filter element, and after flushing the new primary filter element for 15 minutes, turns off the booster pump 66 and the first solenoid valve 681, and the water purifier enters normal use. At this point, the process of automatic filter element switching is completed.

[0037] When the life of the switched filter element has expired and the original filter element has been replaced and needs to be switched back, the specific switching process is as follows: the valve core 4 of the water purifier pipeline switching valve is rotated counterclockwise to connect the water outlet 3, and the water outlet 3 pipeline is closed to complete the filter element switching. After the filter element switching is completed, the control circuit board 65 marks the used filter element as scrapped, and at the same time starts the booster pump 66, opens the first solenoid valve 681 to start flushing the new primary filter element. After the new primary filter element is flushed for 15 minutes, the booster pump 66 and the first solenoid valve 681 are closed, and the water purifier enters normal use. At this point, the second automatic filter element switching process is completed.

[0038] Two sets of primary filter elements are pre-installed in the water purifier before use. Based on the 6-month life of the primary filter elements, the first filter component 61 and the second filter component 62 are controlled by the water purifier pipeline switching valve to operate in relay, extending the maintenance time of the primary filter elements to 1 year, which is basically the same as the post-RO reverse osmosis membrane 67 and post-activated carbon 69.

[0039] After one year of use or during regular maintenance, the primary filter set marked as scrapped is removed and replaced with a new one. The replaced filter set is marked as fully functional to complete the filter replacement. This relay operation effectively extends the lifespan of the primary filter, allowing maintenance personnel to complete filter replacements during the scheduled maintenance process. This eliminates the need for dedicated visits to replace the primary filter, effectively reducing the frequency of maintenance.

[0040] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
