Description

Technical Field

[0001] The present invention relates to the technical field of water purifiers, and particularly to a quick-change water purifier filter device. Background Art

[0002] Traditional water purifiers usually adopt a multi-stage series filter element structure, such as PP cotton, activated carbon, RO membrane, etc. The filter elements need to be replaced regularly to ensure the filtering efficiency. However, the filter element replacement process is cumbersome: the water source needs to be turned off, the outer shell needs to be disassembled, tools need to be used to turn the interface, and finally the filter element inside the filter needs to be manually taken out and a new filter element needs to be replaced at the same time. The replacement of such filters is relatively complex, and the water purifier filter devices are generally installed in multiple groups in a narrow filter box, making the actual installation and replacement operations very time-consuming and laborious. At present, in order to facilitate disassembly and replacement, a snap-fit installation is mostly adopted between the filter cartridge and the cartridge cover. Although this installation method can facilitate disassembly and replacement, its service life is relatively low, and water leakage is likely to occur after multiple disassembly and replacements. Therefore, the convenient disassembly, replacement and maintenance of the water purifier filter devices on the market have always been a difficult problem to solve.

[0003] Therefore, how to provide a quick-change water purifier filter device is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] An object of the present invention is to provide a quick-change water purifier filter device, which can automatically realize the rotary disassembly operation between the filter cartridge and the filter cover, and can also tilt the filter device at a certain angle to facilitate the replacement operation in a narrow filter box.

[0005] According to an embodiment of the present invention, a quick-change water purifier filter device includes a filter box, a filter device is arranged in the filter box, two groups of damping rollers are respectively arranged on both sides below the filter device, a water storage tank communicated with the bottom of the filter device is arranged at the bottom of the filter box, and a clamp-shaped frame is arranged above the filter device;

[0006] A clamping mechanism is arranged in the filter box. The clamping mechanism includes a driving motor, a bidirectional screw rod and four groups of transmission blocks. The four groups of transmission blocks are arranged on both sides of the bidirectional screw rod in a pairwise corresponding manner and are connected by opposite-thread threads. The movement of the transmission blocks drives the damping rollers on both sides of the filter device to move towards each other to clamp the filter device.

[0007] A side-swing mechanism is arranged on one side of the transmission block. The side-swing mechanism includes a limit slide rail and a push-pull frame. The top of the push-pull frame is fixed to the output rod of the electric telescopic rod. The electric telescopic rod is fixed inside the filter box. The limit slide rail is movably connected to the push-pull frame through a telescopic shaft pin. One side of the transmission block is horizontally slidably connected to the limit slide rail through a limit slider.

[0008] Further, the drive motor is fixed inside the filter box. The output shaft of the drive motor is drivingly connected to the middle position of the bidirectional screw through a transmission gear. Both ends of the bidirectional screw are movably connected to the filter box through bushings. On the side of the transmission block away from the limit slider, an installation assembly is also fixedly connected.

[0009] Further, the installation assembly further includes an installation plate and an inner frame. Both sides of the inner frame are slidably connected to the vertical sliding rods fixed on the surface of the installation plate through side ears. On the upper and lower sides of the vertical sliding rods close to the side ears of the inner frame, support springs are respectively sleeved. The inner frame is elastically connected to one side of the installation plate through the support springs.

[0010] Further, a torque motor is fixedly connected inside the inner frame. The output shaft of the torque motor is drivingly connected to the damping roller through a gear set. Two groups of damping rollers are respectively movably arranged at both ends of one side of the inner frame. The gear set is composed of several groups of meshing gears.

[0011] Further, a connecting push rod is also fixedly connected to the surface of the push-pull frame. The top of the connecting push rod is movably connected to an inclined push rod through a sliding shaft pin. One end of the inclined push rod away from the connecting push rod is movably connected to a connecting ear.

[0012] Further, the connecting ear is fixedly connected to one side of the clamp frame. There is a certain gap between the clamp frame and the filter.

[0013] Further, a vertical sliding groove is vertically opened at the top of the filter box close to the connecting push rod. The sliding shaft pin between the connecting push rod and the inclined push rod is slidably connected in the vertical sliding groove.

[0014] Further, a horizontal sliding rail is fixedly connected to the inner surface of the filter box. One side of the clamp frame is slidably connected in the horizontal sliding rail through a slider.

[0015] The beneficial effects of the present invention are as follows:

[0016] After the torque motor inside the inner frame of the installation assembly provided by the present invention is started, its top output shaft can directly drive the two groups of damping rollers to rotate in the same direction through the gear set. The damping rollers are in close contact with the surface of the filter. In this way, the damping rollers in the rotating state can directly drive the filter to rotate under the action of static friction, so that the filter cartridge and the filter cover of the filter are rotationally separated. At the same time, the rotating and separating filter provides a downward force to the damping rollers, so that the inner frame squeezes the support springs on the surface of the vertical sliding rods, realizing a stable separation effect until the filter cartridge and the filter cover of the filter are completely separated. Compared with the traditional manual disassembly using tools, it can effectively save labor output;

[0017] In the present invention, through the bidirectional screw provided, after the driving motor is started, the bidirectional screw can be directly driven to rotate inside the filter box by the transmission gear. At this time, the four groups of transmission blocks on the surface of the bidirectional screw move in opposite threaded directions in pairs under the restriction of the limit sliders and limit slide rails, thereby driving the placement assembly and the damping roller to move in opposite directions, making it convenient to disassemble the whole filter. Conversely, it provides a better gripping effect under the filter cartridge of the filter, stabilizing the normal use of the filter.

[0018] In the present invention, through the side swing mechanism provided, under normal circumstances, the electric telescopic rod pushes the telescopic shaft pin rod on one side of the limit slide rail through the push-pull frame. In this way, when the transmission block receives the rotation of the bidirectional screw, it can have a lateral movement effect. When the electric telescopic rod pulls the push-pull frame upward, at this time the telescopic shaft pin rod expands and contracts, and at the same time the whole limit slide rail rotates around the axis of the bidirectional screw, causing the whole transmission block to also have a certain angle of yaw. In this way, the placement assembly, the damping roller and the whole filter will swing, making the position at the top of the filter separate from the filter cover, thus facilitating the operation of taking and replacing the filter element inside the filter.

[0019] In the present invention, through the inclined push rod provided, when the electric telescopic rod pulls the push-pull frame upward, the push-pull frame will synchronously drive the connecting push rod upward. At this time, the pin shafts at the movable parts of the connecting push rod and the inclined push rod will slide vertically in the vertical chute. The bottom position of the inclined push rod moves vertically, while its top pushes the connecting ear and the clamping frame to move laterally outward. At the same time, under the action of the horizontal slide rail, the lateral movement effect of the clamping frame is stabilized. In this way, the clamping frame can cooperate with the filter to move a certain distance, thereby stabilizing the position of the filter and preventing the filter from falling off from inside the filter box.

[0032] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0033] Refer to Figures 1-8 , including a filter box 1, a filter 2 is arranged in the filter box 1, two groups of damping rollers 3 are respectively arranged on both sides below the filter 2, a water storage tank 4 communicated with the bottom of the filter 2 is arranged at the bottom of the filter box 1, and a clamp-shaped frame 5 is arranged above the filter 2;

[0034] A clamping mechanism 6 is arranged in the filter box 1. The clamping mechanism 6 includes a drive motor 61, a bidirectional screw 63 and four groups of transmission blocks 64. The four groups of transmission blocks 64 are arranged on both sides of the bidirectional screw 63 in a pairwise corresponding manner and are connected by opposite threads. The movement of the transmission blocks 64 drives the damping rollers 3 on both sides of the filter 2 to move towards each other to clamp the filter 2 under force;

[0035] On one side of the transmission block 64, a side-swing mechanism 7 is provided. The side-swing mechanism 7 includes a limit slide rail 73 and a push-pull frame 72. The top of the push-pull frame 72 is fixed to the output rod of the electric telescopic rod 71. The electric telescopic rod 71 is fixed inside the filter box 1. The limit slide rail 73 and the push-pull frame 72 are movably connected through a telescopic shaft pin rod. One side of the transmission block 64 is horizontally slidably connected to the limit slide rail 73 through a limit slider 74.

[0036] In this implementation scheme, the filter 2 is the same as most spiral-connected filtering devices on the current market. It is composed of a filter cartridge, a filter element, and a filter cover. The filter cover above it is directly clamped and fixed by the filter box 1. The filter cartridge below is stably clamped inside the filter box 1 through the damping rollers 3. The damping rollers 3 are connected to the clamping mechanism 6. When the drive motor 61 is started, the bidirectional screw 63 can rotate inside the filter box 1. At this time, the four transmission blocks 64 move in opposite directions in pairs on the surface of the bidirectional screw 63, synchronously driving the two damping rollers 3 on both sides below the filter 2 to move in opposite directions. This effect can clamp or loosen the filter 2 by the damping rollers 3, so as to facilitate the replacement operation and provide a certain stable effect below the filter 2.

[0037] A limit slide rail 73 is provided on one side of the transmission block 64. The limit slide rail 73 is directly movably connected to the push-pull frame 72 through a telescopic shaft pin rod. The telescopic shaft pin rod means that there are side ears on one side, and its rod body can perform a certain degree of telescopic movement. Here, it can also be replaced by a flexible material. When the electric telescopic rod 71 pulls the push-pull frame 72, the push-pull frame 72 moves upward and drives the limit slide rail 73 through the telescopic shaft pin rod. The limit slide rail 73 and the transmission block 64 are limited and slid relative to each other through the limit slider 74, so that the limit slide rail 73 rotates around the bidirectional screw 63, changing the specific angular position of the transmission block 64.

[0038] Reference Figures 3-5 The drive motor 61 is fixed inside the filter box 1. The output shaft of the drive motor 61 is connected to the middle position of the bidirectional screw 63 through a transmission gear 62. Both ends of the bidirectional screw 63 are movably connected to the filter box 1 through shaft sleeves. On the side of the transmission block 64 away from the limit slider 74, an installation component 65 is also fixedly connected. The installation component 65 also includes an installation plate 651 and an inner frame 653. Both sides of the inner frame 653 are slidably connected to the vertical slide rods 652 fixed on the surface of the installation plate 651 through side ears. On the upper and lower sides of the surface of the vertical slide rod 652 close to the side ears of the inner frame 653, support springs 654 are respectively sleeved. The inner frame 653 is elastically connected to one side of the installation plate 651 through the support springs 654. A torque motor 655 is fixedly connected inside the inner frame 653. The output shaft of the torque motor 655 is connected to the damping roller 3 through a gear set 656. The two damping rollers 3 are respectively movably arranged at both ends on one side of the inner frame 653. The gear set 656 is composed of several groups of meshing gears.

[0039] In this implementation, under normal circumstances, the damping roller 3 is in contact with the lower surface of the filter 2. After the driving motor 61 is started, its output shaft directly drives the bidirectional screw 63 to rotate inside the filter box 1 through the connection of the transmission gear 62. The four groups of transmission blocks 64 move in pairs correspondingly, thereby driving the placement assembly 65 to displace. The placement assembly 65 mainly includes a placement plate 651 and an internal frame 653, and the damping roller 3 is directly movably arranged on both sides of one end of the internal frame 653. In this way, the damping roller 3 can follow the overall movement of the placement assembly 65 to clamp or loosen the filter 2. After the torque motor 655 inside the internal frame 653 is started, the top output shaft of the torque motor 655 will directly drive the damping roller 3 to rotate through the gear set 656. Under the action of the static friction force between the damping roller 3 and the filter 2, the filter 2 rotates, causing the filter cartridge and the filter cover limited by the top of the filter box 1 to rotate, and the filter cartridge and the filter cover gradually separate. During the separation process, the filter cartridge drives the damping roller 3 to move downward. At this time, the downward movement effect will directly drive the internal frame 653 to squeeze the support spring 654 on the surface of the vertical slide bar 652 until the filter cartridge and the filter cover are completely separated. In this way, compared with the traditional operation of disassembling the filter cover with tools, the disassembly efficiency is higher, and the output of labor can be saved more effectively.

[0040] Reference Figure 5 、 Figure 6 and Figure 8 Moreover, a connecting push rod 75 is also fixedly connected to the surface of the push-pull frame 72. The top of the connecting push rod 75 is movably connected to an inclined push rod 76 through a sliding shaft pin. One end of the inclined push rod 76 away from the connecting push rod 75 is movably connected to a connecting ear 77. The connecting ear 77 is fixedly connected to one side of the clamping frame 5. There is a certain gap between the clamping frame 5 and the filter 2. A vertical sliding groove 78 is vertically opened at the top of the filter box 1 near the connecting push rod 75. The sliding shaft pin between the connecting push rod 75 and the inclined push rod 76 slides in the vertical sliding groove 78.

[0041] In this implementation, when the push-pull frame 72 moves up and down under the drive of the electric telescopic rod 71, the connecting push rod 75 will move synchronously under force. The top of the connecting push rod 75 is movably connected to the inclined push rod 76 through a sliding shaft pin, and this sliding shaft pin slides vertically in the vertical sliding groove 78. In this way, the bottom position of the inclined push rod 76 receives an upward thrust, and the connecting ear 77 connected to its top is fixed to one side of the clamping frame 5, so that the whole clamping frame 5 receives a lateral thrust, enabling it to stably slide in the horizontal slide rail 79. In cooperation with the yaw operation of the filter 2 by the transmission block 64 during the angle change process, at the same time, under the restriction of the clamping frame 5, the position of the filter 2 can be more effectively stabilized, preventing the filter 2 from falling.

[0042] Reference Figures 7-8 Moreover, a horizontal slide rail 79 is fixedly connected to the inner surface of the filter box 1. One side of the clamping frame 5 is slidably connected to the horizontal slide rail 79 through a slider.

[0043] In this embodiment, the horizontal slide rail 79 provides the stability for the lateral movement of the clamp-shaped frame 5, so that the thrust of the connecting ear 77 can stably provide the effect of the lateral movement of the clamp-shaped frame 5 here.

[0044] Working principle: When it is necessary to replace the filter element inside the filter 2, first start the driving motor 61. The driving motor 61 directly drives the bidirectional screw 63 to rotate inside the filter tank 1 through the transmission gear 62. One side of the transmission block 64 is limited by the limit slider 74 and the limit slide rail 73, so that the transmission block 64 makes a lateral movement under the rotation effect of the transmission gear 62. The other side of the transmission block 64 is connected to the placement assembly 65. One end of the placement assembly 65 is connected to two damping rollers 3. In this way, the two damping rollers 3 can move towards each other to clamp the position of the filter cartridge below the filter 2. Subsequently, the torque motor 655 in the placement assembly 65 is started. Under the transmission effect of the gear set 656, the two damping rollers 3 rotate, so as to drive the spiral separation between the filter cartridge below the filter 2 and the filter cover at the top under the action of static friction. During the separation process of the filter cartridge, it continuously moves downward. At this time, the damping roller 3 will drive the built-in frame 653 to slide downward on the vertical slide rod 652 on the surface of the placement plate 651, and at the same time compress the support spring 654 until the filter cartridge and the filter cover are completely separated. Subsequently, adjust the driving amounts of the driving motor 61 and the electric telescopic rod 71. After the electric telescopic rod 71 is started, it can pull the push-pull frame 72 upward. On the one hand, the push-pull frame 72 drives the limit slide rail 73 to rotate around the pin of the bidirectional screw 63 through the telescopic shaft pin. Here, the driving motor 61 needs to maintain the same driving amount. At this time, the transmission block 64 drives the placement assembly 65, the damping roller 3, and the filter cartridge below the filter 2 to deflect a certain angle, so that the filter cartridge and the filter cover are separated. On the other hand, when the push-pull frame 72 rises, it will synchronously drive the connecting push rod 75 to rise. The top of the connecting push rod 75 is movably connected to the inclined push rod 76 through a sliding shaft rod, and at the same time, the sliding shaft rod slides in the vertical chute 78 to achieve limitation. In this way, the top of the inclined push rod 76 will provide a thrust to the connecting ear 77, and the connecting ear 77 is fixed on one side of the clamp-shaped frame 5. The clamp-shaped frame 5 is horizontally limited and slides in the horizontal slide rail 79, so that the clamp-shaped frame 5 can follow the filter 2 to deflect a certain angle, providing better stability for the filter 2 and preventing the filter 2 from falling off. Finally, only the internal filter element needs to be taken out. After installing a new filter element, repeat the above operation to achieve closure, and the water enters the filter 2 for purification and then enters the storage tank 4 for storage.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
