Description

Technical Field

[0001] The present invention relates to the technical field of water purifiers, and more particularly to a convenient anti-misalignment installation water purifier. Background Art

[0002] A water purifier is a device specially designed to improve the purity of water. It uses an efficient filter system to effectively remove impurities and harmful substances in water, thereby providing cleaner and safer drinking water. As the core element of the performance of a water purifier, the filter plays a vital role. However, as the use time accumulates, the purification efficiency of the filter will gradually reach the limit of its service life. Therefore, in order to ensure the continuous and stable water purification effect, it is particularly important to replace the filter of the water purifier regularly.

[0003] In the prior art, the filter element and its mounting seat are generally connected by a spiral structure, and rely on a sealing gasket to achieve a tight sealing effect. Under normal operating conditions, the water flow at the inlet of the water purifier will first be finely filtered by the filter element, and then the pure water will flow to the outlet of the water purifier. However, when replacing a new filter element, if the filter element is misplaced during the installation process, the sealing gasket will not be able to perform its due sealing function, causing the water at the inlet of the water purifier to bypass the filter element and flow directly into the outlet of the water purifier through the tiny gap between the filter element and the mounting seat. In this case, the filtering function of the filter element will be completely ineffective. What is even more tricky is that users often find it difficult to intuitively judge whether the water purifier filter element is installed misplaced in daily use, which increases the risk of use.

Specifically, the inlet seat 2 is used to connect with the water source pipe, and the outlet seat 3 is used to connect with the water outlet pipe. A middle body plate 4 is arranged inside the casing 1 and below the inlet seat 2 and the outlet seat 3. The middle body plate 4 comprises a circular ring piece 401 connected with the inside of the casing 1, and a plurality of through holes 402 for passing water are evenly arranged on the through hole 402. A cover 403 is vertically arranged on the circular ring piece 401 and located on the inner side of the through hole 402. A plug hole 404 is arranged at the upper center of the cover 403, and flow holes 405 are arranged on the upper part of the cover 403 and on both sides of the plug hole 404. An inner ring column 406 is vertically arranged in the middle of the circular ring piece 401, and an inner thread is arranged on the inner wall of the inner ring column 406.

[0035] A connecting pipe 5 is provided above the middle body plate 4 , the outlet of the connecting pipe 5 is connected to the outlet seat 3 , a boss 501 for inserting into the insertion hole 404 is provided at the through hole below the connecting pipe 5 , and the outer wall of the boss 501 is tightly sealed with the insertion hole 404 .

[0036] A filter element 6 is provided below the middle body disc 4, and the filter element 6 includes a filter cartridge 601. A joint 602 for screwing into the internal thread of the inner ring column 406 is provided above the filter cartridge 601. A sealing ring 7 is provided on the top of the joint 602 for sealing with the lower surface of the boss 501. A sealing ring 2 8 is provided on the top of the filter cartridge 601 for sealing with the lower surface of the circular ring sheet 401. A filter screen 603 for filtering is provided on the side of the filter cartridge 601.

[0037] Specifically, water flows from the inlet seat 2 into the interior of the casing 1, then flows into the outside of the filter element 6 through the through hole 402 of the middle body plate 4, flows into the interior of the filter element 6 after being filtered by the filter mesh 603, and the filtered water flows into the interior of the connecting pipe 5 from the through hole below the connecting pipe 5, and finally flows out through the outlet seat 3.

[0038] When replacing the filter element 6, it is necessary to unscrew the old filter element 6, then align the connector 602 of the new filter element 6 with the internal thread of the inner ring column 406, and screw the connector 602 into the internal thread of the inner ring column 406 in a correct position, so that the sealing ring 1 7 can ensure that the top surface of the connector 602 is tightly sealed with the lower surface of the boss 501, and the sealing ring 2 8 can ensure that the top surface of the filter cartridge 601 is tightly sealed with the lower surface of the circular ring sheet 401, and the sealing ring 1 7 and the sealing ring 2 8 play a double sealing role.

[0039] A motor 9 is provided at the top of the casing 1, and the rotating shaft of the motor 9 passes through the top of the casing 1. The rotating shaft of the motor 9 is tightly sealed with the top of the casing 1. A power disk 10 is provided on the rotating shaft of the motor 9. The power disk 10 includes a thick ring disk 101. Two trapezoidal grooves 102 are symmetrically provided on the thick ring disk 101. Two blocking slide bars 11 are symmetrically provided below the power disk 10. The upper ends of the blocking slide bars 11 are round heads that contact the thick ring disk 101 and the trapezoidal grooves 102. The middle part of the blocking slide bar 11 is slidably connected with a double slide seat 12. The double slide seat 12 is fixed. It is fixed on the inner wall of the casing 1, and a spring 13 is provided between the blocking slide bar 11 and the double slide seat 12. A blocking ring 14 is provided at the bottom of the two blocking slide bars 11. The blocking ring 14 is provided with a disc having the same number as the through holes 402 and used to block the through holes 402. The disc of the blocking ring 14 is provided with a sealing sheet 15 sealed with the upper surface of the circular ring sheet 401; the two flow holes 405 of the middle body disc 4 are connected to the flow tubes 16, and the upper end openings of the two flow tubes 16 are provided with blocking blocks 17 for blocking, and the two blocking blocks 17 are respectively fixed on the corresponding blocking slide bars 11.

[0040] Specifically, when the round head at the upper end of the blocking slide bar 11 contacts the trapezoidal groove 102, the spring 13 provides elastic force, the blocking slide bar 11 is in the upper position, the disc of the blocking ring 14 is separated from the through hole 402, the water flows normally through the through hole 402, and the blocking block 17 contacts the upper end opening of the flow tube 16, the blocking block 17 blocks the upper end opening of the flow tube 16, and prohibits the water from flowing from the flow tube 16 into the cover 403.

[0041] The rotating shaft of the starter motor 9 rotates sixty degrees in the positive direction, and the round head of the upper end of the blocking slide bar 11 slides from the trapezoidal groove 102 to contact with the thick ring disk 101. The blocking slide bar 11 is in the lower position, and the spring 13 is compressed. The blocking slide bar 11 separates the blocking block 17 from the upper end opening of the flow tube 16, and the spring 13 drives the blocking ring 14 and the sealing sheet 15 to move downward. The sealing sheet 15 contacts the upper surface of the circular ring sheet 401, and the water flow no longer flows through the through hole 402. At the same time, the water flow enters the cover 403 from the upper end opening of the flow tube 16. If the filter element 6 is installed misplaced so that the sealing ring 7 has no sealing effect, water will flow out from the joint. The water enters the interior of the filter element 6 through the gap between the top surface of 602 and the lower surface of the boss 501, and thus also flows out from the outlet seat 3; if the filter element 6 is installed misaligned and the sealing ring 2 8 has no sealing effect, the water will flow to the outside of the filter element 6 through the gap between the top surface of the filter cartridge 601 and the lower surface of the annular sheet 401, and then enter the interior of the filter element 6 from the filter screen 603, and also flow out from the outlet seat 3; therefore, if water flows out of the outlet seat 3 at this time, it can be judged that the filter element 6 is installed misaligned; if there is no water flowing out of the outlet seat 3, it can be judged that the filter element 6 is installed correctly, the sealing ring 1 7 and the sealing ring 2 8 play a sealing role, and the filter element 6 also plays a filtering role.

[0042] A clamping plate 502 is provided inside the connecting pipe 5 and between the boss 501 and the outlet of the connecting pipe 5, a center hole 503 is provided on the clamping plate 502, and a side hole 504 concentric with the center hole 503 is provided on the side wall of the connecting pipe 5; a cross plate seat 18 is provided inside the connecting pipe 5, a middle slide rod 19 is slidably provided on the cross plate seat 18, a sealing plate 20 for blocking the center hole 503 is provided at one end of the middle slide rod 19, a sealing plate 21 for blocking the side hole 504 is provided at the other end of the middle slide rod 19, and a T-shaped plate 23 is provided on the upper part of the sealing plate 21.

[0045] Specifically, when the lever 26 is not in contact with the T-shaped plate 23, the spring 22 provides elastic force so that the sealing ring 4 25 on the sealing plate 21 is in close contact with the side of the connecting pipe 5, and water will not flow through the side hole 504, while the sealing ring 3 24 on the sealing plate 1 20 is separated from the clamping plate 502, and water will flow through the sealing ring 3 24.

[0046] The rotating shaft of the starter motor 9 rotates sixty degrees in the opposite direction, and the lever 26 drives the T-plate 23 to move away from the connecting pipe 5. The sealing ring four 25 on the sealing plate two 21 is separated from the side of the connecting pipe 5, and the water will flow through the side hole 504 into the interior of the connecting pipe 5. At the same time, the sealing ring three 24 on the sealing plate one 20 contacts the clamping plate 502 to block the middle hole 503, and the water will not flow through the middle hole 503. Therefore, the water will enter the interior of the filter element 6 from the lower through hole of the connecting pipe 5, and then flow to the outside of the filter element 6 through the filter screen 603, so it can wash away the impurities adsorbed on the outer surface of the filter screen 603.

A spring 44 is connected between the water drainage slide 43 and the double slide seat 12. The water drainage slide 43 passes through the connecting pipe 5, and the water drainage slide 43 is tightly sealed with the connecting pipe 5.

[0050] Specifically, when the round head of the upper end of the drain slide 43 contacts the thin ring disk 421, the drain slide 43 is in the upper position, the lower end of the drain slide 43 contacts the pressure ring 31, and the drain slide 43 does not drive the pressure ring 31 to move downward, the spring three 40 provides elastic force, the sealing ring six 41 on the bottom sealing block 37 is tightly sealed with the bottom inner wall of the bottom shell 27, and water will not flow out from the sewage outlet 271; the rotating shaft of the starter motor 9 is rotated sixty degrees in the opposite direction, and the round head of the upper end of the drain slide 43 is released from the thin ring disk The drain slide bar 43 moves downward, the spring four 44 is compressed, the drain slide bar 43 drives the pressure ring 31 to move downward, and the power is transmitted through the connecting rod 1 32, so that the inclined slide bar 33 slides downward along the inclined slide bar 34, and then the power is transmitted through the connecting rod 2 35, so that the inclined rod 36 and the bottom sealing block 37 move upward at the same time, the spring three 40 is compressed, and the sealing ring six 41 on the bottom sealing block 37 is separated from the bottom inner wall of the bottom shell 27, and the sewage flows out from the sewage discharge port 271.

The sealing ring six 41 on the bottom sealing block 37 is tightly sealed with the inner wall of the bottom of the bottom shell 27, and water will not flow out from the sewage outlet 271; the lever 26 does not contact the T-plate 23, and the spring two 22 provides elastic force, so that the sealing ring four 25 on the sealing plate two 21 is in close contact with the side of the connecting pipe 5, and water will not flow through the side hole 504, while the sealing ring three 24 on the sealing plate one 20 is separated from the clamping plate 502, and water will flow through the sealing ring three 24; under normal working conditions, water flows from the inlet seat 2 into the interior of the casing 1, and then flows into the outside of the filter element 6 through the through hole 402 of the middle body plate 4, and flows into the interior of the filter element 6 after being filtered by the filter screen 603, and the filtered water flows into the interior of the connecting pipe 5 from the through hole below the connecting pipe 5, and finally flows out through the outlet seat 3.

[0052] When the used filter element 6 needs to be replaced, first unscrew the bottom shell 27 from the bottom of the casing 1, separate the pressure ring 31 from the bottom of the drain slide 43, then unscrew the used filter element 6, and then align the connector 602 of the new filter element 6 with the internal thread of the inner ring column 406, and screw the connector 602 into the internal thread of the inner ring column 406 in the correct position, so that the sealing ring 1 7 can ensure that the top surface of the connector 602 is tightly sealed with the lower surface of the boss 501, and the sealing ring 2 8 can ensure that the top surface of the filter cartridge 601 is tightly sealed with the lower surface of the circular ring sheet 401, and the sealing ring 1 7 and the sealing ring 2 8 play a double sealing role. Finally, screw the bottom shell 27 back into the bottom of the casing 1, the pressure ring 31 contacts the drain slide 43 again, and the sealing ring 5 28 plays a sealing role.

[0053] Considering that the filter element 6 will not play a filtering role after the filter element 6 is installed out of position, the rotating shaft of the starter motor 9 is rotated sixty degrees in the positive direction, and the upper round head of the blocking slide bar 11 slides from the trapezoidal groove 102 to contact the thick ring disk 101, so that the blocking slide bar 11 moves to the lower position, and the spring 13 is compressed. At this time, the upper round head of the drain slide bar 43 is still in contact with the thin ring disk 421, and the lever 2 is not in contact with the T-plate 23. The blocking slide bar 11 separates from the upper opening of the flow tube 16 with the block 17, and the spring 13 drives the blocking ring 14 and the sealing sheet 15 to move downward, and the sealing sheet 15 contacts the upper surface of the circular ring sheet 401, and the water flow no longer flows through the through hole 402. At the same time, the water flow enters the cover 4 from the upper opening of the flow tube 16. 03, if the filter element 6 is installed incorrectly and the sealing ring 1 7 has no sealing effect, water will enter the interior of the filter element 6 from the gap between the top surface of the joint 602 and the lower surface of the boss 501, and thus also flow out from the outlet seat 3; if the filter element 6 is installed incorrectly and the sealing ring 2 8 has no sealing effect, water will flow to the outside of the filter element 6 through the gap between the top surface of the filter cartridge 601 and the lower surface of the annular sheet 401, and then enter the interior of the filter element 6 from the filter screen 603, and also flow out from the outlet seat 3; therefore, the filter element 6 can be judged to be installed incorrectly by the outflow of water from the outlet seat 3; the filter element 6 can be judged to be installed correctly by the absence of water outflow from the outlet seat 3, the sealing ring 1 7 and the sealing ring 2 8 play a sealing role, and the filter element 6 also plays a filtering role.

[0054] Taking into account that after the filter element 6 is used, impurities will be attached to the surface of the filter screen 603, and it is necessary to rinse from the inside of the filter screen 603 to the outside in order to better remove the attached impurities, the rotating shaft of the starter motor 9 is rotated sixty degrees in the opposite direction, and the lever 26 drives the T-plate 23 to move away from the connecting pipe 5, and the sealing ring four 25 on the sealing plate two 21 is separated from the side of the connecting pipe 5. At this time, the round head of the upper end of the blocking slide bar 11 slides from the trapezoidal groove 102 to contact with the thick ring disk 101, and the blocking slide bar 11 moves to the lower position. With the same principle as above, the water flow no longer flows through the through hole 402, and the water will flow through the side hole 504 into the interior of the connecting pipe 5. At the same time, the sealing ring three 24 on the sealing plate one 20 contacts with the clamping plate 502 to block the middle hole 503, and the water will not flow through the middle hole 50 3, so water will enter the interior of the filter element 6 from the lower through hole of the connecting pipe 5, and then flow to the outside of the filter element 6 through the filter screen 603, so it can better wash the impurities adsorbed on the outer surface of the filter screen 603; at the same time, the round head of the upper end of the water discharge slide rod 43 slides from the thin ring disk 421 to the trapezoidal platform 422, the water discharge slide rod 43 moves downward, the spring four 44 is compressed, the water discharge slide rod 43 drives the pressure ring 31 to move downward, and transmits power through the connecting rod one 32, so that the inclined slide bar 33 slides downward along the inclined slide bar 34, and then transmits power through the connecting rod two 35, so that the inclined rod 36 and the bottom sealing block 37 move upward at the same time, the spring three 40 is compressed, and the sealing ring six 41 on the bottom sealing block 37 is separated from the bottom inner wall of the bottom shell 27, and the sewage containing impurities finally flows out from the sewage discharge port 271.

[0055] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
