Description

Technical Field

[0001] The invention relates to the technical field of water purification components, and in particular to a negative hydrogen ion water purification device. Background Art

[0002] The negative hydrogen ion water purification component is a special filter element that can produce or release negative hydrogen ions. This filter element can not only remove impurities, suspended matter, odors, etc. in the water, but also use the antioxidant properties of negative hydrogen ions to help remove free radicals in the water. It can improve the taste of water to a certain extent and help maintain the health of the drinker.

[0003] In the prior art, there is a filter element of the form shown in the patent number: CN106422447B, and the patent name is: Filter element, filter element assembly and water purification equipment. In order to ensure that water can fully contact the filter element and remove impurities in the water as much as possible, this filter element generally extends the path length of water through the filter element to enhance the water purification effect of the filter element. However, in this design, compared with the other positions, the side of the filter element that first contacts the water has the most adsorbed impurities. Therefore, after the filter element is used for a long time, impurities are easily accumulated at this position, causing blockage, and eventually the filter element needs to be replaced.

[0004] Existing filter elements are usually connected to water pipes by threaded connection, which means that the tight meshing relationship between the screw and the nut needs to be maintained for a long time. After a long period of tight threaded connection, the meshing between the screw and the nut is affected by factors such as diffusion between molecules, and the difficulty of separation will increase, making it difficult for operators to unscrew the nut from the screw, which in turn increases the difficulty of users replacing filter elements.

[0005] Therefore, a negative hydrogen ion water purification device is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a negative hydrogen ion water purification device to reduce the difficulty of operation when replacing a filter element.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A negative hydrogen ion water purification device comprises a base, a placement groove is provided on the base, a filter unit is arranged in the placement groove, a disassembly and assembly device is provided on the base, the disassembly and assembly device positions the filter unit by means of magnetic force, a docking device is provided on the base, a sliding tube and a latch are arranged in the docking device, and the sliding tube and the latch are driven by magnetic force and elastic force to fix the filter unit.

[0009] Based on this scheme, when the present invention is in use, the external water inlet pipe and water outlet pipe are fixedly installed on the docking device respectively, and the water inlet pipe and the water outlet pipe are docked and positioned on the filter unit respectively through the docking device. When the filter unit needs to be replaced, the cooperation between the clamp and the buckle of the disassembly and assembly device is first released to release the fixation of the filter unit. At this time, the docking device will also simultaneously release the positioning of the water inlet pipe and the water outlet pipe on the filter unit. At this time, the operator can directly remove the filter unit from the placement slot. Subsequently, the new filter unit can be placed in the placement slot, and the clamp and the buckle can be re-fastened to achieve the installation of the filter unit. This simplifies the operation of disassembling the filter unit and reduces the difficulty of replacing the filter element.

[0010] Preferably, the disassembly and assembly device includes two magnets 1 respectively arranged at both ends of the placement groove, and two magnets 2 for engaging with the two magnets 1 are fixedly installed on both ends of the filter unit, and a sealing ring is fixedly installed on the magnets 2; two clips are symmetrically fixedly installed on each of the magnets 1, and a plurality of buckles matching the clips are fixedly installed on the outer wall of the filter unit.

[0011] Through this solution, during assembly, the filter unit can be initially fixed by the mutual attraction of two magnets 1 and two magnets 2, so that the operator can free both hands to simultaneously perform the fastening operation of the two clips and their corresponding buckles, thereby simplifying the operation. In addition, because the operator can operate the two clips at the same time, the two torques received by the filter unit during the fastening process of the clips and the buckles offset each other, thereby preventing the filter unit from deviating from the installation position due to flipping, which helps to ensure the stability of the position of the filter unit during the installation process and is conducive to improving the installation efficiency and stability of the filter unit. After installation, the fastening force between the clips and the buckles will squeeze the sealing ring, thereby enabling the sealing ring to seal the gap between magnets 1 and 2 to prevent water leakage.

[0012] When the filter unit needs to be disassembled, the clip and buckle can be directly engaged. At this time, under the mutual magnetic attraction of magnet 1 and magnet 2, the filter unit will not fall directly from the placement slot, which helps to avoid unnecessary falling and cleaning work. Then, the filter unit is removed from the placement slot, and the disassembly operation of the filter unit is completed.

[0013] It can be seen from the above that the present invention can stably install the filter unit without disassembling and installing the threads, and at the same time simplifies the operation of installing and disassembling the filter unit and reduces the difficulty of replacing the filter element.

[0014] Preferably, the docking device includes two slide grooves provided on the base, a sliding tube is movably installed in each of the slide grooves, the two sliding tubes are respectively used to connect the external water inlet pipe and the water outlet pipe, and the two magnets are respectively fixedly installed on the ends of the two sliding tubes; a limiting disk is fixedly installed on the sliding tube, a guide groove and a receiving groove are provided in the base, the guide groove and the receiving groove are connected to each other, a pulling rope is fixedly installed on the limiting disk, the pulling rope passes through the guide groove, a latch is fixedly installed on the other end of the pulling rope, the latch is movably installed in the receiving groove, a thrust spring is fixedly installed in the receiving groove, and the other end of the thrust spring is fixedly installed on one end of the latch; a reset spring is fixedly installed on the limiting disk, and the other end of the reset spring is fixedly installed on the base; a slot is provided on the filter unit.

[0015] Through this scheme, when there is no filter unit installed in the placement slot, due to the action of the reset spring, the sliding tube and the limit plate will retreat in the direction away from the placement slot, and under the pulling force of the pull rope, the latch will overcome the elastic force of the thrust spring and shrink into the storage slot. When the filter unit is installed in the placement slot, under the mutual magnetic force between the magnet one and its corresponding magnet two, the sliding tube will overcome the elastic force of the reset spring and gradually move in the direction of the filter unit. At the same time, since the limit plate also moves synchronously, the pull rope is gradually released downward, so the latch extends from the storage slot under the action of the thrust spring. Finally, after the two magnets one and the two magnets two are respectively attracted, the water inlet pipe and the water outlet pipe are also docked to the filter unit, and the latch is also inserted into the slot on the filter unit, thereby completing the positioning of the filter unit. In addition, without releasing the mutual attraction relationship between the magnet one and the magnet two, the latch will not be able to withdraw from the slot, and thus the filter unit cannot be removed, which is conducive to improving the positioning reliability of the filter unit. In addition, the dual positioning effects of the latch and the magnetic force are also helpful in ensuring the accuracy of positioning, reducing the difficulty of subsequent fastening of the clip and the buckle, and further helping to reduce the difficulty of operation of the present invention.

[0016] When releasing the positioning of the filter unit by the docking device, the filter unit and a sliding tube are held by both hands respectively, and the two are separated, so that the attraction relationship between the magnet 2 on the end of the filter unit and the corresponding magnet 1 is released, and at the same time, the sliding tube and the limit plate thereon will move in the direction away from the placement slot, so that the latch will be pulled out of the slot and returned to the storage slot by the action of the pulling rope, and the filter unit can be directly taken out from the placement slot, and then the attraction of the magnet 1 and the magnet 2 at the other end is released, and the filter unit can be completely removed. In this disassembly process, it is only necessary to overcome the magnetic force between the magnet 1 and the magnet 2 to achieve disassembly, and the magnet 1 and the magnet 2 are used as positioning components rather than fastening components, so the magnetic force between the two can be appropriately reduced in the design without affecting the positioning effect, thereby reducing the difficulty of operation of the present invention to the greatest extent possible.

[0017] In addition, the two polarities of the two magnets one on the side close to the center of the placement slot can be arranged oppositely, and the two polarities of the two magnets two on the side away from the center of the placement slot can also be arranged oppositely. Through this arrangement, when the filter unit is installed in the placement slot, the polarity of the magnet can be used to determine whether the installation posture of the filter unit is correct, thereby enabling the user to more easily and correctly install the filter unit and reduce the difficulty of operation when replacing the filter element.

[0018] Preferably, a rotating buckle is rotatably installed in the placement groove, a tension spring is fixedly installed on the rotating buckle, the other end of the tension spring is fixedly installed on the inner wall of the placement groove, and a plug hole for inserting or resisting the plug pin is opened on the rotating buckle.

[0019] By this arrangement, when the filter unit is not installed in the placement slot, the tension spring limits the rotation of the rotating buckle, so that the rotating buckle is against the base in a posture of opening outward from the base, and the projection area of ​​the jack on the cross section of the plug is smaller than the area of ​​the cross section of the plug, so that the plug cannot pass through the jack at this time, and the end of the plug is against the side wall of the jack. When the filter unit is placed in the placement slot, the filter unit first contacts the rotating buckle, and as the filter unit is gradually placed in the placement slot, the rotating buckle is gradually rotated, and the tension spring is also stretched. At the same time, the projection area of ​​the jack on the cross section of the plug is gradually increased, until the projection area of ​​the jack on the cross section of the plug is greater than or equal to the cross section of the plug, the end of the plug that originally abuts against the jack pops out and passes through the jack under the action of the thrust spring, and then is inserted into the slot, and at the same time, the plug will also limit the rotation of the rotating buckle by cooperating with the jack, so the tension spring cannot reset the rotating buckle. At the same time, due to the effect of the pulling rope, when the latch pops out, the sliding tube will also move toward the filter unit due to the connection of the pulling rope, and finally the magnet 1 on the sliding tube and the magnet 2 on the filter unit will be attracted to complete the positioning.

[0020] Therefore, on the one hand, the latch will not extend into the placement slot when the filter unit is not installed in the placement slot, thereby ensuring that the latch will not hinder the placement operation of the filter unit in the placement slot; on the other hand, due to the obstruction of the socket to the latch, when the latch does not pop out of the socket, the reaction force applied to the latch by the rotating buckle can be used to balance the elastic force of the thrust spring, thereby ensuring that the elastic force of the thrust spring will not affect the reset spring. Therefore, it can be ensured that the reset spring at this time keeps the sliding tube in a position away from the placement slot, thereby ensuring that when the filter unit is installed in the placement slot, magnet one will not be attracted to magnet two in advance, thereby avoiding the generation of unnecessary friction caused by premature attraction of magnet one and magnet two, thereby reducing the operating difficulty of the present invention.

[0021] Preferably, a reinforcing shaft is fixedly installed in the rotating buckle, and the reinforcing shaft includes two shaft portions and a ring portion, the two shaft portions are fixedly connected to the ring portion, and the two shaft portions are symmetrically arranged on the ring portion, and the shaft portion and the ring portion are both steel components; the shaft portion is rotatably installed on the base, the central axis of the ring portion and the central axis of the socket are the same axis, and the central hole of the ring portion is used for passing a pin.

[0022] Through this arrangement, when the bolt abuts against the side wall of the socket, the portion where the socket is located can be supported by the ring portion of the reinforcing shaft, thereby improving the structural strength of the socket portion, preventing the socket portion from being deformed and damaged due to the extrusion of the bolt, and improving the service life and reliability of the present invention. At the same time, this also means that the reinforcing shaft is the main force-bearing component that abuts against the bolt, so a suitable design of the strength of the reinforcing shaft can enable the socket to stably abut against the bolt, and the other parts of the rotating buckle can be made of other materials with lower strength and easier to process, such as plastic, thereby saving the manufacturing cost of the present invention.

[0023] Preferably, a receiving groove is provided in the socket, and the receiving groove is used to abut against the side wall surface of the plug; a blocking part is fixedly installed in the receiving groove, and the blocking part is used to abut against the end of one end of the plug inserted into the socket.

[0024] Through this arrangement, the blocking portion is arranged to protrude from the bottom of the receiving groove, so that when the bolt and the jack are against each other, the bolt will be inserted into the receiving groove, and the end of the bolt inserted into the receiving groove will be against the blocking portion in the receiving groove, so that the blocking portion can limit the sliding of the bolt along the bottom of the receiving groove. In addition, when the bolt and the blocking portion are against each other, the direction of the torque applied to the rotating buckle by the bolt through the blocking portion is the same as the direction of the torque applied to the rotating buckle by the tension spring, so that the rotating buckle can maintain the posture opened to the outside of the base and against the base, so as to facilitate the user to place and install the filter unit. At this time, the elastic force of the tension spring and the thrust spring both enable the rotating buckle to maintain an open state, so that the stability of the posture of the rotating buckle can be better guaranteed. The stability of the posture of the rotating buckle can in turn ensure the stability of the abutting relationship between the blocking portion and the bolt, which is conducive to preventing the bolt from accidentally popping out of the jack due to factors such as shaking, thereby improving the reliability of the present invention during use and the stability of the structure.

[0025] Preferably, a round chamfer is provided in the guide groove, a diverter is fixedly installed in the guide groove, and the diverter is fixedly installed at the connecting portion between the guide groove and the receiving groove.

[0026] With this arrangement, during the working process of the present invention, when the pulling rope slides in the guide groove and needs to turn, the pulling rope will bend against the round chamfer, so that it can be bent in a gentle manner, avoiding damage to the pulling rope caused by large-angle bending. At the same time, the diverter can separate the two pulling ropes installed on the latch, thereby preventing the two pulling ropes from being entangled, thereby improving the reliability of the present invention.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. By providing a disassembly and assembly device and a docking device, when the present invention is used, if it is necessary to replace the filter unit, the clamp and buckle of the disassembly and assembly device are first released to release the fixation of the filter unit. At the same time, the docking device will also synchronously release the positioning of the water inlet pipe and the water outlet pipe on the filter unit. At this time, the operator can directly remove the filter unit from the placement slot. Subsequently, the new filter unit can be placed in the placement slot, and the clamp and buckle can be re-fastened to achieve the installation of the filter unit. This simplifies the operation of disassembling the filter unit and reduces the difficulty of replacing the filter element.

[0029] 2. By providing a rotating buckle and a tension spring, on the one hand, the latch will not extend into the placement slot when the filter unit is not installed in the placement slot, thereby preventing the latch from obstructing the placement operation of the filter unit in the placement slot; on the other hand, the elastic force of the thrust spring will not affect the reset spring, so that when the filter unit is installed in the placement slot, magnet one will not be attracted to magnet two in advance, thereby avoiding the generation of unnecessary friction caused by premature attraction of magnet one and magnet two, thereby reducing the operating difficulty of the present invention.

[0030] 3. By providing the accommodating groove and the blocking portion, when the latch pin abuts against the blocking portion, the direction of the torque applied to the rotating buckle by the latch pin through the blocking portion is the same as the direction of the torque applied to the rotating buckle by the tension spring, so that the rotating buckle can maintain a posture open to the outside of the base and abut against the base, thereby facilitating the user to place and install the filter unit, and can better ensure the stability of the posture of the rotating buckle, and also help to prevent the latch pin from accidentally popping out of the socket due to shaking and other factors, thereby improving the reliability of the present invention during use and the stability of the structure.

DETAILED DESCRIPTION

[0042] The following content will use the drawings listed in the aforementioned "Description of Drawings" section to clearly explain the specific implementation methods of the present invention, in the hope that readers can have a more complete and objective understanding of the working principle of the present invention and the corresponding technical effects.

[0043] like Figures 1 to 10 As shown, a specific implementation of the present invention is shown. Among them, several points need to be explained in advance: First, the clip 32 and buckle 33 in this embodiment can actually adopt a variety of self-locking buckle structures that already exist in the prior art. In this embodiment, a box buckle, specifically a duckbill buckle, is used as the form of the clip 32 and the buckle 33; second, in the drawings of this embodiment, in order to show the structure, the clip 32 and the buckle 33 are not fastened together, and in actual use, the user should fasten the clip 32 and the buckle 33 to ensure the stable installation of the present invention; third, since the sealing ring is a common and mature sealing method in the prior art, in order to simplify the figure elements, the sealing ring is not shown in the figure. Specifically, the sealing ring should be installed as shown in the figure. Figure 4 As shown, the junction of magnet 1 22 and magnet 2 31 is sealed; fourthly, in order to reduce the magnetic interference between magnet 1 22 and magnet 2 31 and other components, the components adjacent to magnet 1 22 and magnet 2 31 can be made of plastic or other non-magnetic materials.

[0047] In addition, a rotating buckle 4 is rotatably installed in the placement groove 12, and a tension spring 43 is fixedly installed on the rotating buckle 4. The other end of the tension spring 43 is fixedly installed on the inner side wall of the placement groove 12, and a plug hole 42 for inserting the plug 123 or resisting the plug 123 is opened on the rotating buckle 4. A reinforcing shaft 41 is fixedly installed in the rotating buckle 4. The reinforcing shaft 41 includes two shaft portions 412 and a ring portion 411. The two shaft portions 412 are fixedly connected to the ring portion 411, and the two shaft portions 412 are symmetrically arranged on the ring portion 411. The shaft portions 412 and the ring portion 411 are both steel components; the shaft portion 412 is rotatably installed on the base 1, and the central axis of the ring portion 411 is the same axis as the central axis of the plug hole 42. The central hole of the ring portion 411 is used to insert the plug 123. A receiving groove 421 is provided in the plug hole 42, and the receiving groove 421 is used to abut against the side wall surface of the plug pin 123; a blocking portion 422 is fixedly installed in the receiving groove 421, and the blocking portion 422 is used to abut against the end of the plug pin 123 inserted into the plug hole 42. The two polarities of the two magnets 1 22 on the side close to the center of the placement groove 12 are opposite, and the two polarities of the two magnets 2 31 on the side away from the center of the placement groove 12 are opposite. A round chamfer 132 is provided in the guide groove 13, and a shunt portion 131 is fixedly installed in the guide groove 13, and the shunt portion 131 is fixedly installed at the connection part between the guide groove 13 and the receiving groove 121.

[0048] When the present invention is working, the external water inlet pipe and water outlet pipe are fixedly installed on the docking device respectively, and the water inlet pipe and the water outlet pipe are docked and positioned on the filter unit 3 respectively through the docking device. When the filter unit 3 needs to be replaced, the clamp 32 and the buckle 33 of the disassembly device are first released to release the fixation of the filter unit 3. At this time, the docking device will also simultaneously release the positioning of the water inlet pipe and the water outlet pipe on the filter unit 3. At this time, the operator can directly remove the filter unit 3 from the placement slot 12. Subsequently, the new filter unit 3 can be placed in the placement slot 12, and the clamp 32 and the buckle 33 can be re-fastened to achieve the installation of the filter unit 3. This simplifies the operation of disassembling the filter unit 3 and reduces the difficulty of replacing the filter element.

[0049] Among them, during assembly, the present invention can preliminarily fix the filter unit 3 by mutual attraction of two magnets 1 22 and two magnets 2 31, so that the operator can free both hands to perform the fastening operation of the two clips 32 and their corresponding buckles 33 at the same time, thereby simplifying the operation. In addition, because the operator can operate the two clips 32 at the same time, the two torques received by the filter unit 3 during the fastening process of the clips 32 and the buckles 33 offset each other, thereby preventing the filter unit 3 from deviating from the installation position due to flipping, which helps to ensure the stability of the position of the filter unit 3 during the installation process, and is conducive to improving the installation efficiency and stability of the filter unit 3. After the installation is completed, the fastening force between the clips 32 and the buckles 33 will squeeze the sealing ring, thereby enabling the sealing ring to seal the gap between the magnets 1 22 and the magnets 2 31 to prevent water leakage.

[0050] When the filter unit 3 needs to be disassembled, the clip 32 and the buckle 33 can be directly engaged. At this time, under the mutual magnetic attraction of the magnet 1 22 and the magnet 2 31, the filter unit 3 will not fall directly from the placement slot 12, which helps to avoid unnecessary falling and cleaning work. Then, the filter unit 3 is removed from the placement slot 12, and the disassembly operation of the filter unit 3 is completed.

[0051] It can be seen from the above that the present invention can stably install the filter unit 3 without disassembling and installing the threads, and at the same time simplifies the operation of installing and disassembling the filter unit 3 and reduces the difficulty of replacing the filter element.

[0052] In addition, when the filter unit 3 is not installed in the placement slot 12, due to the action of the return spring 212, the sliding tube 2 and the limit plate 21 will retreat in the direction away from the placement slot 12, and under the pulling force of the pull rope 211, the latch 123 will overcome the elastic force of the push spring 122 and shrink into the receiving slot 121. When the filter unit 3 is installed in the placement slot 12, under the mutual magnetic force between the magnet 1 22 and the corresponding magnet 2 31, the sliding tube 2 will overcome the elastic force of the return spring 212 and gradually move in the direction of the filter unit 3. At the same time, since the limit plate 21 also moves synchronously, the pull rope 211 is gradually released downward, so that the latch 123 extends from the receiving slot 121 under the action of the push spring 122. Finally, after the two magnets 1 22 and the two magnets 2 31 are attracted to each other, the water inlet pipe and the water outlet pipe are also connected to the filter unit 3, and the latch 123 is also inserted into the slot 34 on the filter unit 3, thereby completing the positioning of the filter unit 3. Moreover, without releasing the mutual attraction relationship between the magnets 1 22 and the magnets 2 31, the latch 123 will not be able to withdraw from the slot 34, and thus the filter unit 3 cannot be removed, which is conducive to improving the positioning reliability of the filter unit 3. In addition, the dual positioning effect of the latch 123 and the magnetic force is also conducive to ensuring the accuracy of positioning, reducing the difficulty of the subsequent buckling of the clip 32 and the buckle 33, and thus more conducive to reducing the difficulty of operation of the present invention.

[0053] When the positioning of the filter unit 3 by the docking device is released, the filter unit 3 and a sliding tube 2 are held by both hands respectively, and the two are separated, then the magnet 2 31 on the end of the filter unit 3 and the corresponding magnet 1 22 are released, and at the same time, the sliding tube 2 and the limit plate 21 thereon will move in the direction away from the placement slot 12, so that the latch 123 will be pulled out of the slot 34 and returned to the receiving slot 121 by the action of the pulling rope 211, and the filter unit 3 can be directly taken out from the placement slot 12, and then the magnet 1 22 and the magnet 2 31 at the other end are released, and the filter unit 3 can be completely removed. In this disassembly process, it is only necessary to overcome the magnetic force between the magnet 1 22 and the magnet 2 31 to achieve disassembly, and the magnet 1 22 and the magnet 2 31 are used as positioning components rather than fastening components, so the magnetic force between the two can be appropriately reduced in the design without affecting the positioning effect, thereby reducing the difficulty of operation of the present invention to the greatest extent possible.

[0054] In addition, the two polarities of the two magnets 1 22 on the side close to the center of the placement slot 12 can be arranged oppositely, and the two polarities of the two magnets 2 31 on the side away from the center of the placement slot 12 can also be arranged oppositely. Through this arrangement, when the filter unit 3 is installed in the placement slot 12, the polarity of the magnet can be used to determine whether the installation posture of the filter unit 3 is correct, thereby enabling the user to more easily and correctly install the filter unit 3 and reduce the difficulty of operation when replacing the filter element.

[0055] It is worth adding that Figure 8 As shown, combined with Figure 5 , Figure 7 By comparison, it can be seen that when the plug 123 abuts against the insertion hole 42, the plug 123 will be inserted into the receiving groove 421, and the end of the plug 123 inserted into the receiving groove 421 abuts against the blocking portion 422 in the receiving groove 421, so that the blocking portion 422 can limit the sliding of the plug 123 along the bottom of the receiving groove 421. In addition, when the plug 123 abuts against the blocking portion 422, the direction of the torque applied to the rotating buckle 4 by the plug 123 through the blocking portion 422 is the same as the direction of the torque applied to the rotating buckle 4 by the tension spring 43, so that the rotating buckle 4 can maintain the posture of opening outside the base 1 and abut on the base 1, so that the user can place and install the filter unit 3 conveniently. At this time, the elastic force of the tension spring 43 and the thrust spring 122 both enable the rotating buckle 4 to maintain the open state, so that the stability of the posture of the rotating buckle 4 can be better guaranteed. The stability of the position of the rotating buckle 4 can in turn ensure the stability of the abutment relationship between the blocking portion 422 and the latch 123, which is beneficial to prevent the latch 123 from accidentally popping out of the socket 42 due to shaking or other factors, thereby improving the reliability and structural stability of the present invention during use.
