[0042] Embodiment one

[0043] Reference Figures 1-8 As shown in the specific embodiment of the water purification equipment with the built-in RO membrane filter core of the present application, comprising a water purification equipment body 100, a water faucet 101 for water outlet is arranged on the water purification equipment body 100, further comprising a filter assembly 200 and an RO membrane filter core 300, the filter assembly 200 is arranged in the water purification equipment body 100, the RO membrane filter core 300 is detachably connected to the filter assembly 200, the filter assembly 200 comprises a pretreatment mechanism 201 and a locking mechanism 204;

[0044] The pretreatment mechanism 201 comprises a pre-filter cylinder 2011 and a valve plate two 2018, in normal state, the RO membrane filter core 300 is sleeved with the outer peripheral surface of the pre-filter cylinder 2011, the valve plate two 2018 is located in the pre-filter cylinder 2011 and is slidably connected with the pre-filter cylinder 2011, the pretreatment mechanism 201 is used for driving the valve plate two 2018 to slide downward in the pre-filter cylinder 2011 by the entering of water flow and making the water flow flow into the RO membrane filter core 300;

[0045] The locking mechanism 204 comprises a cam 2042, when the valve plate two 2018 slides downward in the pre-filter cylinder 2011, the cam 2042 converts the downward driving force of the linear motion of the valve plate two 2018 into the rotating force of the cam 2042 itself and extrudes and clamps the RO membrane filter core 300, the locking mechanism 204 is used for water locking when the pretreatment mechanism 201 is connected with the RO membrane filter core 300, and water unlocking.

[0046] The RO membrane filter core 300 comprises an outer shell 301, in normal state, the inner wall of the outer shell 301 is sleeved on the outer wall of the pre-filter cylinder 2011, the inner wall of the outer shell 301 is fixedly provided with a pressing part 302, the pressing part 302 is an arc structure which is gradually curved to the axis from the upper outer wall to the lower outer wall.

[0047] The pre-treatment mechanism 201 further comprises valve seat one and valve seat two arranged at the bottom end and the top end of the pre-filtering cylinder 2011, the valve seat one is internally fixed with a partition plate two 2012, the partition plate two 2012 divides the cavity in the valve seat one into cavity one and cavity two from bottom to top, the valve seat two is internally fixed with a partition plate one 2010, the partition plate one 2010 divides the cavity in the valve seat two into cavity three and cavity four from bottom to top, the upper end outlet of the valve seat one is slidably provided with a valve clack one 2013, the upper end outlet of the valve seat two is slidably provided with a valve clack two 2018, the valve seat one of the pre-filtering cylinder 2011 is symmetrically provided with a water passage 2019 communicated between the cavity one and the cavity three.

[0048] The shaft center of the valve clack one 2013 is fixedly provided with a communicating pipe 2017, the outer circumferential surface of the communicating pipe 2017 is sleeved with a spring one 2015, the outer circumferential surface of the spring one 2015 is sleeved with a sleeve 2014, the spring one 2015 and the sleeve 2014 are located in the cavity three;

[0049] The other end of the communicating pipe 2017 penetrates the sleeve 2014, the communicating pipe 2017 is uniformly provided with a plurality of through holes on the outer wall located in the cavity four, the top end of the communicating pipe 2017 is fixedly provided with a connecting column 2016, the other end of the connecting column 2016 is fixedly connected with the valve clack two 2018.

[0050] When the water flow enters the pre-treatment mechanism 201, it first enters the cavity one of the valve seat one. Due to the existence of the cavity one, the water flow will be preliminarily buffered and pressure-stabilized here, reducing the impact force of the water flow; then, the water flow flows upward from the cavity one, is blocked when passing through the partition plate two 2012, and thus enters the cavity three through the water passages 2019 on both sides. In the cavity three, the water flow continues to be buffered and adjusted, preparing for the subsequent treatment, then the water flow extrudes the valve clack one 2013 to open the top opening connection between the valve clack one 2013 and the top of the valve seat one, at this time the water flow enters the cavity two, and can avoid that the local water flow is too large or too small, in the cavity two, the water flow gradually spreads from the bottom of the hollow communicating pipe 2017 to the top of the communicating pipe 2017 through the hollow communicating pipe 2017, and flows into the cavity four through the through holes on the outer wall of the communicating pipe 2017 located in the cavity four;

[0051] In the cavity three, the water flow contacts the valve clack one 2013. As the water flow continuously flows in, the water pressure in the cavity three gradually rises, when the downward pushing force generated by the water pressure is greater than the initial elastic force of the spring one 2015, the valve clack one 2013 starts to slide downward, in the process of sliding downward of the valve clack one 2013, the communicating pipe 2017 fixed at the shaft center thereof also moves downward. When the communicating pipe 2017 moves downward, on one hand, the spring one 2015 is compressed, and on the other hand, the valve clack two 2018 is driven to move downward synchronously through the connecting column 2016.

[0052] At this time, the water flows into the fourth cavity through the plurality of through holes on the outer wall of the fourth cavity, spreads upward, and then flows into the space above through the open through hole of the second valve seat and the second valve disc, and finally flows into the RO membrane filter core 300 for further filtration.

[0053] Further, as described above, when the water flows into the third cavity, the water pressure rises, and a downward thrust is generated on the first valve disc 2013. The communication pipe 2017 fixed at the center of the first valve disc 2013 is connected to the second valve disc 2018 through the connecting column 2016. Therefore, when the first valve disc 2013 slides downward under the action of the water pressure, the second valve disc 2018 is driven to move downward through the communication pipe 2017 and the connecting column 2016. At the same time, the spring 2015 is compressed when the first valve disc 2013 moves downward, and stores elastic potential energy to provide power for the reset of the first valve disc 2013 and the second valve disc 2018 when the water is stopped.

[0054] As shown in FIG. 6, the locking mechanism 204 includes a mounting rod 2041 eccentrically fixed on the upper end surface of the second valve disc 2018, and a hinged rod three 2044 hingedly arranged at the other end of the mounting rod 2041. Figures 4 to 6

[0055] The top end of the pre-filter cylinder 2011 is symmetrically fixed with a support rod 2043, and a cam 2042 is rotatably arranged between the two support rods 2043. The cam 2042 is eccentrically connected to the other end of the hinged rod three 2044.

[0056] When the second valve disc 2018 moves downward under the action of the water flow, the mounting rod 2041 eccentrically fixed on the upper end surface of the second valve disc 2018 also moves downward. The other end of the mounting rod 2041 is hingedly arranged with the hinged rod three 2044, and the hinged rod three 2044 swings as the mounting rod 2041 descends.

[0057] Since the top end of the pre-filter cylinder 2011 is symmetrically fixed with the support rod 2043, and the cam 2042 is rotatably arranged between the two support rods 2043, and the cam 2042 is eccentrically connected to the other end of the hinged rod three 2044. Therefore, when the hinged rod three 2044 swings, the cam 2042 rotates around the support rod 2043.

[0058] ​Further, during the rotation of the cam 2042, the eccentric structure thereof will gradually approach the pressing part 302 on the inner wall of the shell 301 of the RO membrane filter core 300. With the continuous rotation of the cam 2042, the pressing part 302 is extruded, and since the pressing part 302 is an arc-shaped structure that is gradually curved from the upper outer wall to the shaft center, the extrusion makes the connection between the RO membrane filter core 300 and the pre-filter cylinder 2011 more compact, thereby achieving the locking of the RO membrane filter core 300 and ensuring the stable operation of the filter core in the water passing state;

[0059] In summary, in the working process of the water purification equipment filtering assembly 200, after the water flow enters the pretreatment mechanism 201, it is buffered and pressure stabilized in the cavity one of the valve seat one, and then enters the cavity three through the water passage 2019. In the cavity three, the water flow drives the valve disc one 2013 to move downward, and the valve disc one 2013 drives the valve disc two 2018 to descend synchronously through the communication pipe 2017 and the connecting column 2016. At the same time, the water flow extrudes the valve disc one 2013 to open the top opening connection between the valve disc one 2013 and the valve seat one, at this time the water flow enters the cavity two, in the cavity two the water flow gradually spreads from the bottom of the hollow communication pipe 2017 to the top of the communication pipe 2017 through the hollow communication pipe 2017, and flows into the cavity four through the through hole on the outer wall of the communication pipe 2017 in the cavity four, and then enters the space above through the open through port of the valve seat two by the downward displacement of the valve disc two 2018, and flows into the RO membrane filter core 300 for filtration. When the valve disc two 2018 descends, the cam 2042 is driven to rotate through the mounting rod 2041 and the hinged rod three 2044, the cam 2042 rotates to extrude the pressing part 302 of the RO membrane filter core 300, and the function of "water passing locking" is realized. When the water is stopped, the elastic potential energy of the spring one 2015 is released, so that the valve disc one 2013 and the valve disc two 2018 are reset, and the cam 2042 is also reversely rotated, thereby releasing the locking of the RO membrane filter core 300, that is, "water stopping unlocking". This design not only realizes the effective pretreatment and filtration of the water flow, but also ensures the stability of the RO membrane filter core 300 during operation and the convenience during replacement, thereby improving the overall performance of the water purification equipment and the user experience.

[0060] Embodiment two

[0061] Please refer to Figures 1-8 This embodiment is basically the same as embodiment one, and is made on the basis of embodiment one and has the same beneficial effects as embodiment one. The same parts are referred to each other and will not be described in detail here.

[0062] As a further technical scheme of the embodiment, the filtering assembly 200 further comprises an adjusting mechanism 202 and a transmission mechanism 203, the adjusting mechanism 202 is distributed perpendicularly to the pretreatment mechanism 201 and is in communication with the pretreatment mechanism 201, the adjusting mechanism 202 comprises a sliding column 2025, the sliding column 2025 is provided with a passage one and a passage two, the adjusting mechanism 202 is used for controlling the water flow to flow left and right through the sliding column 2025, and the adjusting mechanism 202 is used for determining which passage the water flow flows out through by moving the sliding column 2025 left and right.

[0063] The transmission mechanism 203 comprises a rotating disc 2035, and the transmission mechanism 203 is used for converting the linear motion of the sliding column 2025 into the rotating driving force of the rotating disc 2035.

[0064] The water purification device comprises a water inlet, the adjusting mechanism 202 comprises a mounting cylinder 2022 which is in communication with and fixedly connected with the pre-filter cylinder 2011, the outer wall of the mounting cylinder 2022 is provided with a water receiving pipe 2021 which is in communication with the water inlet, the inner wall of the water receiving pipe 2021 is provided with a flow monitoring meter 2028 which is used for measuring the water flow, and one side of the inner wall of the mounting cylinder 2022 is fixedly provided with an electromagnetic coil 2023.

[0065] The adjusting mechanism 202 is provided with a movable groove, the sliding column 2025 is slidably arranged in the movable groove, one end of the sliding column 2025 is fixedly provided with an electromagnet 2024, the electromagnet 2024 is located in the magnetic force wrapping range of the electromagnetic coil 2023, the other end of the sliding column 2025 is fixedly provided with a mounting ring 2029 on the outer wall, the inner wall of the mounting cylinder 2022 is fixedly provided with a limiting ring 2026, and the outer wall of the sliding column 2025 is further sleeved with a spring two 2027, the spring two 2027 is located between the limiting ring 2026 and the mounting ring 2029.

[0066] When the water flow is small, the water flow is monitored by the flow monitoring meter 2028, the flow monitoring meter 2028 releases a signal to the controller and electrifies the electromagnetic coil 2023, when the electromagnetic coil 2023 electrifies, the electromagnet 2024 is pulled to the left side, and the sliding column 2025 which is fixedly connected with the electromagnet 2024 is also moved to the left side. During the movement, the mounting ring 2029 on the sliding column 2025 compresses the spring two 2027 to store elastic potential energy. At the same time, due to the movement of the sliding column 2025, the positions of the passage one and the passage two provided on the sliding column 2025 are changed, thereby affecting the flow path of the water flow.

[0067] Specifically, when the electromagnetic coil 2023 is not electrified, the water flow passes through the passage one, and when the electromagnetic coil 2023 is electrified, the water flow passes through the passage two.

[0068] Specifically, before pulling the electromagnet 2024, the water flows into the installation cylinder 2022 from the water pipe 2021, at this time the sliding column 2025 is in the initial position, the water flows through the passage two on the sliding column 2025 into the communication part of the adjusting mechanism 202 and the pretreatment mechanism 201, and then flows into the pre-filter cylinder 2011 of the pretreatment mechanism 201. Specifically, the water flow first enters the cavity one of the valve seat one, then enters the cavity two through the passage on the partition plate two 2012, and then enters the cavity three through the water passage 2019, pushing the valve disc one 2013 to move downward. The valve disc one 2013 drives the communication pipe 2017 to move downward, compresses the spring one 2015, and drives the valve disc two 2018 to move downward through the connecting column 2016. The water flow enters the communication pipe 2017 through the through hole on the sleeve 2014, and then enters the space above the valve disc two 2018, and finally flows into the RO membrane filter core 300 for filtration.

[0069] The transmission mechanism 203 further comprises a mounting chuck 2031 fixedly arranged on the inner wall of the end of the sliding column 2025 away from the electromagnet 2024, one end of the mounting chuck 2031 is fixedly provided with a connecting rod 2032, the other end of the connecting rod 2032 is hingedly provided with a hinged rod one 2033, the other end of the hinged rod one 2033 is hingedly provided with a hinged rod two 2034.

[0071] Further, after pulling the electromagnet 2024, the water flow from the water pipe 2021 into the installation cylinder 2022, due to the sliding column 2025 to the left, the water flow at this time through the sliding column 2025 on the passage two into the adjustment mechanism 202 and the communication of the matching cylinder 2036. After entering the matching cylinder 2036, because the sliding column 2025 moves to the left, the mounting chuck 2031 fixed on the inner wall of one end of the electromagnet 2024 will also move to the left. The mounting chuck 2031 drives the connecting rod 2032 fixedly connected thereto to move to the left, and the movement of the connecting rod 2032 is transmitted to the articulated rod one 2033 in a hinged manner. The articulated rod one 2033 transmits the movement to the articulated rod two 2034, and since the other end of the articulated rod two 2034 is eccentrically connected to the rotating disc 2035, this movement ultimately causes the rotating disc 2035 to rotate around the rotating shaft mounted in the inner wall of the matching cylinder 2036. Then the water flow passes through the filter pipe 2037 into the RO membrane filter core 300 for filtration. At the same time, the filter assembly 200 also includes an expanding mechanism 205, which adjusts the opening size of the communication between the matching cylinder 2036 and the filter pipe 2037, so that the water flow can pass more smoothly, avoiding the occurrence of blockage.

[0072] The expanding mechanism 205 includes a bevel gear one 2050 arranged at the communication between the matching cylinder 2036 and the filter pipe 2037, and an opening assembly is arranged in the bevel gear one 2050 for controlling the opening size of the communication between the matching cylinder 2036 and the filter pipe 2037.

[0074] The opening assembly is located in the inner wall of the filter pipe 2037, and the opening assembly includes a sliding disc 2051 connected with the inner wall of the bevel gear one 2050, a plurality of opening pieces are slidably arranged on the sliding disc 2051, and a hexagonal groove 2054 is formed in the sliding disc 2051.

[0075] The opening assembly further includes a matching disc 2052, a plurality of limiting grooves 2053 are uniformly formed in the matching disc 2052 along the axis, and the matching disc 2052 is slidably connected with the opening pieces through the limiting grooves 2053.

[0076] The opening piece comprises a sliding block 2055, one end of the sliding block 2055 is fixedly provided with a sliding column 2056, the other end of the sliding block 2055 is fixedly provided with a limiting column 2057, a plurality of sliding columns 2056 are slidably connected to the sliding disc 2051 through a plurality of hexagonal grooves 2054, and a plurality of limiting columns 2057 are slidably connected to the matching disc 2052 through a plurality of limiting grooves 2053.

[0077] Further, when the rotating disc 2035 rotates, the rotating shaft installed at one end thereof penetrates through the belt wheel two 2059 fixedly arranged at the outer wall of the matching cylinder 2036 and also rotates. The belt wheel two 2059 drives the belt wheel one 2058 to rotate through a belt, and the belt wheel one 2058 is fixedly connected to the bevel gear two 20510, so that the bevel gear two 20510 also rotates. Since the bevel gear two 20510 is in meshing connection with the bevel gear one 2050, the rotation of the bevel gear two 20510 drives the bevel gear one 2050 to rotate. When the bevel gear one 2050 rotates, the sliding disc 2051 connected to the inner wall of the bevel gear one 2050 also rotates. The sliding disc 2051 is provided with a plurality of hexagonal grooves 2054, and the sliding columns 2056 of a plurality of opening pieces are slidably connected to the sliding disc 2051 through the hexagonal grooves 2054, and the limiting columns 2057 of the opening pieces are slidably connected to the matching disc 2052 through the limiting grooves 2053 in the matching disc 2052. When the sliding disc 2051 rotates, the opening pieces are driven to move radially along the hexagonal grooves 2054 and the limiting grooves 2053, so that the opening size of the plurality of opening pieces changes, and the opening size of the communication part between the matching cylinder 2036 and the filtering pipe 2037 is controlled.

[0078] In conclusion, in the working process of the filtering assembly 200, when the water flow changes, the electromagnetic coil 2023 drives the electromagnet 2024 to drive a series of structures to work cooperatively. The adjusting mechanism 202 switches the water flow path through the movement of the sliding column 2025, the transmission mechanism 203 converts the linear motion of the sliding column 2025 into the rotary motion of the rotating disc 2035, and the expanding mechanism 205 adjusts the opening size of the filtering pipe 2037 according to the rotary motion of the rotating disc 2035. Before the electromagnet 2024 is pulled, the water flow mainly enters the RO membrane filter core 300 through the pretreatment mechanism 201; after the electromagnet 2024 is pulled, the water flow path changes, and the water flow enters the RO membrane filter core 300 through the adjusting mechanism 202 and the matching cylinder 2036. This design realizes intelligent adjustment and efficient filtration of the water flow, ensures stable operation of the water purification equipment under different flow conditions, and improves the water purification effect and the service life of the equipment.
