Description

Technical Field

[0001] The utility model relates to the technical field of water filtering equipment, in particular to a foldable filter element unlocking structure. Background Art

[0002] The filter element is a simple device for purifying raw fluid and separating resources, which can purify polluted water to the state required for production and life, that is, to make the water reach a certain degree of cleanliness. It can remove solid particles in the water, kill bacteria, and filter out harmful chemical components. In order to ensure the quality of purified water, the filter element needs to be replaced regularly.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the filter element unlocking in the prior art mostly adopts a rotary snap-on or direct-insert structure. The filter element with a rotary snap-on structure requires a lot of force to unlock, and the operation is very laborious. The handles of the direct-insert structure mostly protrude from the surface of the filter element cover, which is not convenient for moving and transporting, and increases the volume space of the water purifier. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a foldable filter element unlocking structure.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A foldable filter element unlocking structure comprises a filter element seat for installing the filter element, a top seat is arranged on the upper surface of the filter element seat, a receiving groove is opened on the upper surface of the top seat, a handle is rotatably connected to the inner wall of the receiving groove, a mounting hole is opened through the side wall of the filter element seat, a fixing block is arranged in the mounting hole and is slidably connected to the inner wall of the mounting hole, two fixing blocks are symmetrically arranged, and a driving component for driving the two fixing blocks to move simultaneously is installed on the filter element seat.

[0007] By adopting the above technical solution, the filter element is installed at the bottom of the filter element seat, so that the filter element can be locked or unlocked along with the filter element seat. When the filter element needs to be locked, the user drives the two fixing blocks to move away from each other through the driving assembly, so that the two fixing blocks are engaged in the matching grooves. When the filter element needs to be unlocked, the user only needs to turn the opening handle and then use the driving assembly to move the two fixing blocks closer to each other so that the two fixing blocks enter the installation hole, thereby releasing the locking effect of the filter element seat, making it easier to lock or unlock the filter element seat.

[0008] Furthermore, the driving assembly includes a threaded rod that is penetrated and threadedly connected to the filter element seat, a mounting block that is rotatably connected to the lower end of the threaded rod and slidably connected to the inner wall of the mounting hole, and a connecting rod that is rotatably connected to the side wall of the mounting block, one end of the connecting rod away from the mounting block is rotatably connected to the side wall of the fixed block, and the upper end of the threaded rod is fixed to the bottom of the top seat.

[0009] By adopting the above technical solution, when it is necessary to drive the two fixed blocks to move, the user only needs to turn the handle to open it, and then use the handle to rotate the top seat and the threaded rod. Since the threaded rod is threadedly connected to the filter element seat, the threaded rod is rotationally connected to the mounting block, the mounting block is slidingly connected to the inner wall of the mounting hole, and the mounting block and the fixed block are rotationally connected via the connecting rod, the mounting block drives the fixed block to move along the mounting hole during the axial movement of the threaded rod, thereby locking or unlocking the filter element seat.

[0010] Furthermore, an annular gasket is sleeved on the threaded rod, and the annular gasket is arranged between the top seat and the filter element seat.

[0011] By adopting the above technical solution, the annular gasket is made of rubber material, and its surface has a large friction coefficient. When the top seat is rotated to lock the filter element seat, the bottom of the top seat cooperates with the top of the filter element seat and presses against the annular gasket, which increases the friction between the bottom of the top seat and the top of the filter element seat and reduces the probability of automatic rotation of the top seat. In addition, the annular gasket also reduces the wear between the bottom of the top seat and the top of the filter element seat.

[0012] Furthermore, a limiting groove is provided on the inner wall of the accommodating groove, and a limiting block which is plugged and matched with the limiting groove is arranged in the limiting groove.

[0013] By adopting the above technical solution, the limit block is plugged into the limit slot. When the handle needs to be used, the user needs to pull the limit block out of the limit slot, thereby rotating the handle from the receiving slot to open it. After use, the handle is rotated into the receiving slot, and the limit block is inserted into the limit slot again, so that the limit block limits the handle, reducing the probability of the handle rotating automatically.

[0014] Furthermore, a spring is arranged in the limiting groove, one end of the spring is fixed to the inner wall of the limiting groove of the side wall of the limiting block, and the other end of the spring is fixed to the inner wall of the limiting groove.

[0015] By adopting the above technical solution and setting the spring, the limit block maintains the limit state of the handle. When the handle needs to be used, the user only needs to press the limit block with his hand to turn the handle open, reducing the probability of the limit block detaching from the limit groove.

[0016] Furthermore, an installation groove is opened on the inner wall of the accommodating groove, a cross bar is rotatably connected in the installation groove, the handle is fixedly sleeved on the cross bar, a torsion spring sleeved on the cross bar is arranged in the installation groove, one end of the torsion spring is fixed to the inner wall of the installation groove, and the other end of the torsion spring is fixed to the side wall of the handle.

[0017] By adopting the above technical solution and the setting of the torsion spring, after the limit block is pressed into the limit groove, the handle automatically rotates to a state perpendicular to the top seat under the torsion force of the torsion spring, making it convenient for the user to rotate the top seat by the handle.

[0018] Furthermore, a yielding portion cooperating with the handle is provided on the upper surface of the limit block.

[0019] By adopting the above technical solution and setting the yielding part, the limit block is squeezed into the limit groove when the handle is rotated to the accommodating groove, eliminating the tedious operation of the staff to manually press the limit block, and facilitating the rapid limiting of the handle.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the present application, the filter element is installed at the bottom of the filter element seat, so that the filter element is locked or unlocked along with the filter element seat. When the filter element needs to be locked, the user drives the two fixing blocks to move away from each other through the driving assembly, so that the two fixing blocks are engaged in the matching card slots. When the filter element needs to be unlocked, the user only needs to turn the opening handle, and then use the driving assembly to move the two fixing blocks closer to each other, so that the two fixing blocks enter the installation hole, thereby releasing the locking effect of the filter element seat, which is convenient for locking or unlocking the filter element seat;

[0022] 2. In the present application, when the two fixed blocks need to be driven to move, the user only needs to turn the handle to open it, and then use the handle to rotate the top seat and the threaded rod. Since the threaded rod is threadedly connected to the filter element seat, the threaded rod is rotatably connected to the mounting block, the mounting block is slidably connected to the inner wall of the mounting hole, and the mounting block is rotatably connected to the fixed block through the connecting rod, the mounting block drives the fixed block to move along the mounting hole during the axial movement of the threaded rod, thereby locking or unlocking the filter element seat;

[0023] 3. In the present application, the annular gasket is made of rubber material, and its surface has a large friction coefficient. When the top seat is rotated to lock the filter element seat, the bottom of the top seat cooperates with the top of the filter element seat and presses against the annular gasket, which increases the friction between the bottom of the top seat and the top of the filter element seat and reduces the probability of automatic rotation of the top seat. In addition, the annular gasket also reduces the wear between the bottom of the top seat and the top of the filter element seat. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0029] like Figure 1-3 As shown, an embodiment of the present application discloses a foldable filter element unlocking structure, including a filter element seat 1, a top seat 2, a handle 3, a fixing block 4 and a driving assembly 5.

[0030] The filter element seat 1 is used to install the filter element, and a mounting hole 11 is provided through the side wall of the filter element seat 1. The top seat 2 is a round seat-shaped structure, and the top seat 2 is arranged on the upper surface of the filter element seat 1. The axis of the top seat 2 coincides with the axis of the filter element seat 1, and a receiving groove 21 is provided on the upper surface of the top seat 2. The handle 3 is arranged in the receiving groove 21, and the handle 3 is rotatably connected to the inner wall of the receiving groove 21. The fixing block 4 is arranged in the mounting hole 11, and the fixing block 4 is slidably connected to the inner wall of the mounting hole 11, and two fixing blocks 4 are symmetrically arranged.

[0031] The driving assembly 5 is installed on the filter element seat 1, and is used to drive the two fixed blocks 4 to move simultaneously. The driving assembly 5 includes a threaded rod 51, a mounting block 52 and a connecting rod 53. The threaded rod 51 is a vertically arranged rod-shaped structure. The threaded rod 51 is arranged on the filter element seat 1 and is threadedly connected. The upper end of the threaded rod 51 is fixed to the bottom of the top seat 2, and the axis of the threaded rod 51 coincides with the axis of the top seat 2. The mounting block 52 is a rectangular parallelepiped structure. The mounting block 52 is rotatably connected to the lower end of the threaded rod 51, and the mounting block 52 is slidably connected to the inner wall of the mounting hole 11. The connecting rod 53 is rotatably connected to the side wall of the mounting block 52, and the end of the connecting rod 53 away from the mounting block 52 is rotatably connected to the side wall of the fixed block 4.

[0032] The filter element is installed at the bottom of the filter element seat 1, so that the filter element is locked or unlocked with the filter element seat 1. When the filter element needs to be locked, the user only needs to turn the handle 3 to open it, and then use the handle 3 to rotate the top seat 2 and the threaded rod 51. Since the threaded rod 51 is threadedly connected to the filter element seat 1, the threaded rod 51 is rotatably connected to the mounting block 52, and the mounting block 52 is slidably connected to the inner wall of the mounting hole 11. The mounting block 52 and the fixing block 4 are rotatably connected through the connecting rod 53. Therefore, the mounting block 52 drives the fixing block 4 to move along the mounting hole 11 during the axial movement of the threaded rod 51, so that the two fixing blocks 4 move away from each other and engage in the matching grooves. When the filter element needs to be unlocked, the user only needs to turn the handle 3 to open it and rotate the top seat 2 in the opposite direction through the handle 3, so that the two fixing blocks 4 move closer to each other, so that the two fixing blocks 4 enter the mounting hole 11, thereby releasing the locking effect on the filter element seat 1, which is convenient for locking or unlocking the filter element seat 1.

[0033] In order to reduce the probability of automatic rotation of the top seat 2, an annular gasket 6 is sleeved on the threaded rod 51, and the annular gasket 6 is arranged between the top seat 2 and the filter element seat 1. The annular gasket 6 is made of rubber material, and its surface has a large friction coefficient. When the top seat 2 is rotated to lock the filter element seat 1, the bottom of the top seat 2 cooperates with the top of the filter element seat 1 and presses against the annular gasket 6, thereby increasing the friction between the bottom of the top seat 2 and the top of the filter element seat 1, thereby reducing the probability of automatic rotation of the top seat 2. In addition, the annular gasket 6 also reduces the wear between the bottom of the top seat 2 and the top of the filter element seat 1.

[0034] In order to limit the handle 3, a limiting groove 22 is opened on the inner wall of the receiving groove 21, and a limiting block 7 which is plugged into the limiting groove 22 is arranged in the limiting groove 22. The limiting block 7 is plugged into the limiting groove 22. When the handle 3 needs to be used, the user needs to pull the limiting block 7 out of the limiting groove 22, thereby rotating the handle 3 from the receiving groove 21 to open it. After use, the handle 3 is rotated into the receiving groove 21, and the limiting block 7 is inserted into the limiting groove 22 again, so that the limiting block 7 limits the handle 3, thereby reducing the probability of the handle 3 rotating automatically.

[0035] In order to reduce the probability of the limit block 7 being disengaged from the limit groove 22, a spring 8 is arranged in the limit groove 22, one end of the spring 8 is fixed to the inner wall of the limit groove 22 on the side wall of the limit block 7, and the other end of the spring 8 is fixed to the inner wall of the limit groove 22. The setting of the spring 8 enables the limit block 7 to maintain the limiting state of the handle 3. When the handle 3 needs to be used, the user only needs to press the limit block 7 by hand to turn and open the handle 3, thereby reducing the probability of the limit block 7 being disengaged from the limit groove 22.

[0036] In order to make the handle 3 open automatically, a mounting groove 23 is opened on the inner wall of the accommodating groove 21, and a cross bar 9 is rotatably connected in the mounting groove 23. The handle 3 is fixedly sleeved on the cross bar 9, and a torsion spring 10 sleeved on the cross bar 9 is arranged in the mounting groove 23. One end of the torsion spring 10 is fixed to the inner wall of the mounting groove 23, and the other end of the torsion spring 10 is fixed to the side wall of the handle 3. The setting of the torsion spring 10 ensures that after the limit block 7 is pressed into the limit groove 22, the handle 3 automatically rotates to a state perpendicular to the top seat 2 under the torsion force of the torsion spring 10, so that the user can rotate the top seat 2 through the handle 3.

[0037] In order to facilitate the rapid limiting of the handle 3, a yielding portion 71 cooperating with the handle 3 is provided on the upper surface of the limit block 7. The setting of the yielding portion 71 allows the limit block 7 to be squeezed into the limit groove 22 when the handle 3 is rotated to the accommodating groove 21, eliminating the tedious operation of the staff manually pressing the limit block 7, thereby facilitating the rapid limiting of the handle 3.

[0038] The use principle of a foldable filter element unlocking structure in this embodiment is:

[0039] The filter element is installed at the bottom of the filter element seat 1, so that the filter element is locked or unlocked with the filter element seat 1. When the filter element needs to be locked, the user only needs to turn the handle 3 to open it, and then use the handle 3 to rotate the top seat 2 and the threaded rod 51. Since the threaded rod 51 is threadedly connected to the filter element seat 1, the threaded rod 51 is rotatably connected to the mounting block 52, and the mounting block 52 is slidably connected to the inner wall of the mounting hole 11. The mounting block 52 and the fixing block 4 are rotatably connected through the connecting rod 53. Therefore, the mounting block 52 drives the fixing block 4 to move along the mounting hole 11 during the axial movement of the threaded rod 51, so that the two fixing blocks 4 move away from each other and engage in the matching grooves. When the filter element needs to be unlocked, the user only needs to turn the handle 3 to open it and rotate the top seat 2 in the opposite direction through the handle 3, so that the two fixing blocks 4 move closer to each other, so that the two fixing blocks 4 enter the mounting hole 11, thereby releasing the locking effect on the filter element seat 1, which is convenient for locking or unlocking the filter element seat 1.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
