Description

Technical Field

[0001] The present invention relates to the technical field of water purification equipment, and in particular to a water purification filter element disassembly and assembly structure and a water purifier. Background Art

[0002] As people's requirements for drinking water quality continue to increase, water purifiers are increasingly used in daily life. As the core component of a water purifier, the convenience of installation and disassembly as well as the sealing performance of the filter element are crucial to the performance of the entire machine and user experience.

[0003] In the prior art, there are many problems with the installation structure of the filter element. For example, most water purification filter elements are installed by means of an inclined screw-in angle. This structure is prone to wear during long-term use, resulting in a decrease in the matching accuracy, which in turn affects the sealing performance of the filter element and increases the risk of water leakage in the entire machine. Moreover, the locking methods of the water purification filter elements are relatively complex in structure and inconvenient to operate. When replacing the filter element, the filter element needs to be rotated. This operation process requires a lot of effort and has high requirements on the user's operation. It is easy for the filter element to be installed loosely or seal poorly due to improper rotation, which in turn affects the pressure on the sealing docking. It cannot adapt to the more stringent use environment, affecting the service life of the filter element and the overall performance of the water purifier.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a water purification filter element disassembly and assembly structure and a water purifier, aiming to improve the convenience of disassembly and assembly of the water purification filter element and the reliability of subsequent use.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A water purification filter element disassembly and assembly structure comprises a water purifier housing with a filter element mounting cylinder, a water purification filter element mounted in the filter element mounting cylinder, a circulation joint being provided at one end of the water purification filter element, a turning convex tube and a locking block capable of sliding relative to the turning convex tube being provided at the center of the other end of the water purification filter element, the locking block being connected to a handle via a pull rope and the pull rope passes through the turning convex tube, the main pipe section of the turning convex tube coincides with the axis of the water purification filter element and faces the handle, the branch pipe section of the turning convex tube faces the locking block and is provided with a spring to provide the locking block with outward sliding, and a slot matching the locking block is provided in the filter element mounting cylinder of the water purifier housing.

[0007] As a further improvement of the above technical solution, the turning convex pipe is a three-way pipe structure, the turning convex pipe forms two branch pipe sections and the axes of the two branch pipe sections coincide, two locking blocks are provided and are arranged according to the turning convex pipe, and the handle is connected to the corresponding locking blocks through two pull ropes.

[0008] As a further improvement of the above technical solution, the handle includes a pulling guide rod and a folding pull ring. The pulling guide rod includes a transfer handle and a guide column that are combined to form a T-shaped structure. The transfer handle is rotatably connected to the folding pull ring. The guide column is provided with two T-slots for installing a pull rope.

[0009] As a further improvement of the above technical solution, the water purification filter element is provided with a guide sleeve which is sleeved on the locking block to guide the sliding of the locking block.

[0010] As a further improvement of the above technical solution, a guide groove extending along its axial direction and recessed inward is provided on the outer wall of the water purification filter element, and a positioning protrusion cooperating with the guide groove is provided on the cavity wall of the filter element mounting cylinder of the water purifier housing.

[0011] As a further improvement of the above technical solution, magnetic rings are provided in the middle part of the water purification filter element and at the end close to the circulation joint to realize magnetic filtration.

[0012] The present invention also provides a water purifier comprising a water purifier main unit and a water purifier filter element disassembly and assembly structure.

[0013] As a further improvement of the above technical solution, a magnetic block is provided inside the water purifier host to form a magnetic effect with the magnetic ring of the water purifier filter. The magnetic block is used to attract the water purifier filter to move toward the inside of the water purifier host, so that the circulation connector of the water purifier filter is connected to the circulation interface on the water purifier host.

[0014] As a further improvement of the above technical solution, a Hall sensor is provided in the water purifier host, which is used to sense the change in magnetic field strength emitted by the magnetic ring in the water purifier filter and send a signal to the water purifier host to determine whether the water purifier filter is accurately inserted.

[0015] Beneficial effects of the present invention: The water purification filter element disassembly and assembly structure provided by the present invention has the following advantages: 1. Through the cooperation of the lock block and the card slot, after the water purifier filter is installed in place, the lock block is inserted into the card slot under the action of the spring, which can provide a stable connection and seal, reduce the risk of affecting the seal due to long-term wear and tear, effectively improve the sealing performance of the water purifier filter, reduce the possibility of water leakage of the whole machine, and ensure the normal operation of the water purifier and the quality of drinking water.

[0016] 2. The locking structure of the existing water purification filter element is complex, and the filter element needs to be rotated when replaced, which is laborious and requires high user operation. However, with the disassembly and assembly structure of the present invention, the user only needs to pull the handle to install and disassemble the filter element, which is simple and convenient to operate, greatly reducing the user's operating difficulty and effort consumption, and improving the convenience of replacing the filter element.

DETAILED DESCRIPTION

[0025] The present invention provides a water filter element disassembly and assembly structure and a water purifier. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0026] See also Figure 1-Figure 5The present invention provides a water purification filter element 2 disassembly and assembly structure, comprising a water purifier housing 1 with a filter element installation barrel 11, a water purification filter element 2 installed in the filter element installation barrel 11, one end of the water purification filter element 2 is provided with a circulation joint 21, the center of the other end of the water purification filter element 2 is provided with a turning convex pipe 22 and a locking block 23 that can slide relative to the turning convex pipe 22, the locking block 23 is connected to a handle 25 through a pull rope 24 and the pull rope 24 passes through the turning convex pipe 22, the main pipe section 221 of the turning convex pipe 22 coincides with the axis of the water purification filter element 2 and faces the handle 25, the branch pipe section 222 of the turning convex pipe 22 faces the locking block 23 and is provided with a spring 26 that provides the locking block 23 with outward sliding, and a card slot 12 matching the locking block 23 is opened in the filter element installation barrel 11 of the water purifier housing 1.

[0027] When the user installs the water purifier filter 2, first align the circulation joint 21 at one end of the water purifier filter 2 with the interior of the filter element installation cylinder 11, and then push the water purifier filter 2 into the filter element installation cylinder 11. When the locking block 23 at the other end is close to the slot 12 on the water purifier housing 1, the user can pull the handle 25, and the handle 25 drives the locking block 23 through the pull rope 24 to overcome the elastic force of the spring 26, so that the locking block 23 slides back and turns to the side of the branch pipe section 222 of the convex pipe 22, and then pushes the entire water purifier filter 2 straight into the filter element installation cylinder 11, and the circulation joint 21 on the water purifier filter 2 is connected to the circulation interface on the water purifier host 5. When the water purifier filter 2 is installed in place, release the handle 25. Under the action of the spring 26, the locking block 23 slides outward and is stuck in the slot 12 of the water purifier housing 1, thereby realizing the fixed installation of the water purifier filter 2.

[0028] When the user removes the water purification filter element 2, the user first pulls the handle 25, and the handle 25 drives the locking block 23 through the pull rope 24 to overcome the elastic force of the spring 26 and disengage from the slot 12, so that the locking block 23 slides back to the side of the branch pipe section 222 of the protruding pipe 22, and then the entire water purification filter element 2 can be directly pulled out.

[0029] Compared with the existing filter element structures that are mostly installed by tilting the screw-in angle and are easy to wear and cause the sealing performance to decrease, the disassembly and assembly structure of the water purification filter element 2 provided by the present invention has the following advantages: 1. Through the cooperation between the lock block 23 and the card slot 12, after the water purification filter element 2 is installed in place, the lock block 23 is inserted into the card slot 12 under the action of the spring 26, which can provide a stable connection and seal, reduce the risk of affecting the seal due to long-term use and wear, effectively improve the sealing performance of the water purification filter element 2, reduce the possibility of water leakage of the whole machine, and ensure the normal operation of the water purifier and the quality of drinking water.

[0030] 2. The locking structure of the existing water purifier filter 2 is complex, and the water purifier filter 2 needs to be rotated when replaced, which is laborious and requires high user operation. However, with the disassembly and assembly structure of the present invention, the user can install and disassemble the water purifier filter 2 by simply pulling the handle 25, which is simple and convenient to operate, greatly reducing the user's operating difficulty and effort consumption, and improving the convenience of replacing the water purifier filter 2 by the user.

[0031] 3. When the lock block 23 is inserted into the card slot 12, a strong sealing clamping force is formed, which can ensure that the water purification filter element 2 is firmly installed, avoiding the situation that the water purification filter element 2 is not firmly installed or the sealing is poor due to incomplete rotation. Even in a relatively harsh use environment, the normal operation of the water purification filter element 2 can be guaranteed, thereby improving the service life of the water purification filter element 2 and the overall performance of the water purifier, and providing users with more reliable water purification services.

[0032] In order to further improve the firmness and sealing of the installation, the turning convex pipe 22 is a three-way pipe structure, the turning convex pipe 22 forms two branch pipe sections 222 and the axes of the two branch pipe sections 222 coincide, the locking block 23 is provided with two and arranged according to the turning convex pipe 22, and the handle 25 is connected to the corresponding locking block 23 through two pull ropes 24. During operation, when the handle 25 is pulled, the two locking blocks 23 can be subjected to uniform tension at the same time. Compared with the design of a single locking block 23, this structure makes the water purification filter element 2 more balanced in the process of installation and removal, and is not prone to jamming or tilting caused by uneven force, thereby improving the stability and fluency of operation. On the other hand, it increases the reliability and tightness of the connection, and further improves the firmness and sealing performance of the water purification filter element 2 after installation. During use, it can better withstand external forces such as water pressure, reduce the possibility of sealing failure or filter element loosening caused by external forces, thereby extending the service life of the filter element and ensuring the overall performance and water purification effect of the water purifier.

[0033] In order to ensure that the spring 26 is stably placed and installed, the branch pipe section 222 that turns toward the convex pipe 22 is designed with a countersunk head, and the locking block 23 can also be provided with a mounting hole to install the spring 26 and fix the pull rope 24.

[0034] Specifically, the handle 25 includes a pulling guide rod 251 and a folding pull ring 252, wherein the folding pull ring 252 is convenient for the user to hold and apply force. When the installation and removal of the filter element need to be operated, the user can unfold the folding pull ring 252 and easily hold the folding pull ring 252 for pulling operation; when the folding pull ring 252 is not in use, it is folded and stored, and does not interfere with the cover on the water purifier housing 1 to close the filter element installation cylinder 11. The pulling guide rod 251 adopts a transfer handle and a guide column that are combined to form a T-shaped structure. This T-shaped structure has good stability. During the pulling process, it can withstand a large pulling force without being easily deformed or damaged, ensuring the connection stability between the handle 25 and the pull rope 24. At the same time, two T-slots 253 for installing the pull rope 24 are provided on the guide column. The design of the T-slot 253 can better fix the pull rope 24, prevent the pull rope 24 from slipping or shifting during the pulling process, ensure the reliability of the operation, and enable the disassembly and assembly process of the filter element to proceed smoothly.

[0035] In fact, the pull rope 24 is a steel rope with a knot at one end. Workers can quickly and accurately install the knot and the pull rope 24 into the T-slot of the guide column, which improves production efficiency. The knot position can also be fixed by injecting epoxy resin.

[0036] The water purification filter element 2 is provided with a guide sleeve 27 which is sleeved on the lock block 23 and guides the lock block 23 to slide. The guide sleeve 27 is sleeved on the lock block 23, providing a clear sliding track for the lock block 23. During the installation and removal of the filter element, when the pull rope 24 is pulled by the handle 25 to move the lock block 23, the guide sleeve 27 can ensure that the lock block 23 slides accurately in a predetermined direction, avoiding the lock block 23 from being offset, stuck, etc., thereby ensuring that the lock block 23 can smoothly cooperate with or disengage from the card slot 12 in the filter element installation cylinder 11 of the water purifier housing 1, thereby improving the reliability and stability of the water purification filter element 2 disassembly and assembly operation.

[0037] In order to better protect the spring 26 and the pull rope 24 and make the water purification filter element 2 more beautiful, the end of the water purification filter element 2 with the handle 25 is provided with a decorative cover 29, and the decorative cover 29 is combined with the turning convex tube 22 and the guide sleeve 27 to form a circle.

[0038] In order to better ensure that the circulation joint 21 on the water purification filter element 2 is docked with the circulation interface on the water purification host 5, a guide groove 28 extending along its axial direction and recessed inward is provided on the outer wall of the water purification filter element 2, and a positioning protrusion 13 cooperating with the guide groove 28 is provided on the cavity wall of the filter element installation cylinder 11 of the water purifier housing 1. The positioning protrusion 13 and the guide groove 28 play a guiding role in the installation, guiding the user to rotate and adjust the circumferential position of the water purification filter element 2 for installation. When the positioning protrusion 13 cooperates with the guide groove 28, the lateral movement and rotation of the filter element can be limited to a certain extent, ensuring that the circulation joint 21 and the circulation interface are docked smoothly without misalignment.

[0039] Preferably, a magnetic ring is provided in the middle of the water purification filter element 2 and at the end near the circulation joint 21 to realize magnetic filtration. The setting of the magnetic ring can utilize the effect of the magnetic field to adsorb and filter some metal ions and magnetic impurities in the water. When water passes through the water purification filter element 2, the magnetic ring can effectively capture magnetic substances such as iron filings and rust carried in the water, thereby further improving the water purification quality. Combined with traditional filtering methods, it can more comprehensively remove various impurities in the water and provide users with purer and healthier drinking water.

[0040] Furthermore, a magnetic block 4 (such as an iron block) is provided in the water purifier host 5 to form a magnetic effect with the magnetic ring of the water purifier filter 2. The magnetic block 4 is used to attract the water purifier filter 2 to move toward the inside of the water purifier host 5, so that the circulation joint 21 of the water purifier filter 2 is docked with the circulation interface on the water purifier host 5. The magnetic effect between the magnetic block 4 and the magnetic ring of the water purifier filter 2 can generate an attractive force, so that the water purifier filter 2 automatically moves toward the inside of the water purifier host 5 during the installation process. This automatic guidance function greatly simplifies the user's installation operation. The user does not need to perform precise manual alignment. The user only needs to move the filter element close to the installation position, and the magnetic block 4 will attract the filter element to move to the correct docking position, ensuring that the circulation joint 21 is accurately docked with the circulation interface, thereby improving the convenience and efficiency of installation.

[0041] The water purifier host 5 is provided with a Hall sensor 3, which is used to sense the change in the magnetic field strength emitted by the magnetic ring in the water purifier filter 2, and send a signal to the water purifier host 5 to determine whether the water purifier filter 2 is accurately inserted. When the water purifier filter 2 is inserted, the magnetic field generated by its magnetic ring will pass through the Hall element of the Hall sensor 3. Since a constant current passes through the Hall element, according to the Hall effect, the presence of the magnetic field will deflect the electrons in the Hall element, and then generate a Hall voltage proportional to the magnetic field strength on both sides of the Hall element. When the filter element is not inserted, the magnetic field strength around the Hall sensor is weak, and the Hall voltage generated by it is at a lower reference value. As the water purifier filter gradually approaches and is inserted, the magnetic field strength generated by its magnetic ring gradually increases, and the magnetic field strength sensed by the Hall sensor also increases accordingly, and the Hall voltage increases accordingly. When the water purifier filter is accurately inserted into place, the relative position of the magnetic ring and the Hall sensor is fixed, and the magnetic field strength reaches a stable value at this time, and the Hall voltage generated by the Hall sensor is also stable within a specific range. The control circuit in the water purifier host can pre-set the Hall voltage range corresponding to this accurate insertion as a judgment standard. If the water purifier filter is not inserted accurately, for example, the insertion position is offset or not fully inserted, the relative position and magnetic field distribution between the magnetic ring and the Hall sensor will be different from when it is accurately inserted, resulting in the magnetic field strength sensed by the Hall sensor not being within the stable range when accurately inserted, and the corresponding Hall voltage generated will also be lower than the normal range. The water purifier host 5 can provide real-time feedback based on the signal to remind the user. For example, if it is detected that the filter element is not accurately inserted, the water purifier host 5 can prompt the user of the installation error through a display screen, indicator light or sound, and guide the user to re-install the filter element correctly. Compared with the traditional method that relies on mechanical structure or manual judgment, this detection method based on magnetic field induction is more accurate and reliable, and can effectively avoid problems such as equipment operation failure or poor filtering effect caused by inaccurate installation, ensuring that the water purifier can work normally after each filter element replacement, and improving the stability and reliability of the equipment.

[0042] It should be emphasized that the water purifier host 5 can record the magnetic field strength change data detected by the Hall sensor 3 and the corresponding filter element installation time, number of uses and other information. By analyzing these data, the use and life trend of the filter element can be understood, and more accurate filter element replacement prompts can be provided to users. At the same time, it also helps manufacturers collect product usage data, improve quality and optimize design, and improve product performance and reliability. For example, by analyzing a large amount of magnetic field strength data, it can be found that certain specific installation methods or usage environments may affect the installation stability of the filter element, thereby improving product design or providing usage suggestions in a targeted manner.

[0043] Generally speaking, as the temperature rises, the magnetism of the magnetic block will gradually weaken. This will cause the magnetic field interaction between the magnetic block and the Hall sensor 3 to weaken, thereby affecting the intensity of the induction signal output by the Hall sensor 3; at the same time, the temperature will also affect the performance of the Hall sensor 3 itself. The increase in temperature may cause the sensitivity of the Hall sensor 3 to decrease, the noise to increase, and the linearity to deteriorate. For example, in a high temperature environment, the sensitivity of the Hall sensor 3 may decrease by 3% - 5%, thereby weakening its ability to detect changes in the magnetic field, further affecting the accuracy of the induction signal. For this reason, a temperature sensor located next to the Hall sensor 3 is provided in the water purification host 5. The temperature sensor collects the temperature value T in real time, and performs compensation calculations on the induction signal V output by the Hall sensor 3 using a preset algorithm. ,in is the compensation coefficient of the magnetic field strength of the magnetic ring at the current temperature, is the compensation coefficient of the sensitivity of Hall sensor 3, is the sensing signal output by the Hall sensor 3, is the compensated induced signal voltage.

Since the disassembly structure of the water purifier cartridge 2 has been described above, those skilled in the art should be able to understand it in conjunction with the accompanying drawings, and therefore the disassembly structure of the water purifier cartridge 2 will not be described in detail here.
