DETAILED DESCRIPTION

[0031] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only some of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0033] In addition, the utility model further provides a kind of water purification equipment including the above-mentioned self-locking quick-mounting filter element.

[0034] The self-locking quick-mounting filter element provided by the utility model, including filter element main body 1, filter element base 2 and filter element base cover 8, filter element base 2 is equipped with at least one locking piece for cooperating with the filter element locking groove of water purification equipment, the locking piece can be moved along the radial direction of filter element base 2, to drive the rotation of the adjusting screw rod 5 of filter element base 2, the locking piece is connected with the end of adjusting screw rod 5 by connecting rod 4, adjusting screw rod 5 is rotatably connected with filter element base 2 by pivot 51, and the adjusting part of pivot 51 is arranged outside filter element base cover 8;

[0035] Resetting piece is arranged between filter element base 2 and adjusting screw rod 5, and the resetting piece is used to drive the rotation of adjusting screw rod 5, so as to press the locking piece in the filter element locking groove.

[0036] Among them, filter element main body 1 is the main functional structure of filter element for filtering clean water, and filter element base 2 and filter element base cover 8 cooperate with the locking piece, connecting rod 4, adjusting screw rod 5 and resetting piece installed therein to form filter element mounting structure, as shown in Figure 1 .

[0037] Filter element main body 1 and filter element base 2 can be fixedly connected by welding, or can be connected by detachable connection mode such as bolt connection and pin connection, but considering the filtering effect of filter element, in order to avoid the filtered water flowing out through the gap between filter element main body 1 and filter element base 2, filter element main body 1 and filter element base 2 are usually connected by welding.

[0038] Filter element base 2 and filter element base cover 8 are used to enclose the shell of filter element mounting structure, so as to separate filter element main body 1 and filter element mounting structure, improve the appearance of filter element, and filter element base 2 and filter element base cover 8 are preferably connected by detachable connection mode such as buckle connection and screw connection, so as to timely overhaul and replace internal components.

[0039] The locking member is arranged on the outer circumferential surface of the filter element base 2 and is movable in the radial direction of the filter element base 2 to change the cooperation state of the locking member and the filter element locking groove, thereby achieving self-locking or unlocking of the filter element; the structure, shape and distribution of the locking member are determined according to the structure, shape and distribution of the filter element locking groove in actual production;

[0040] The two ends of the connecting rod 4 are connected with the locking member and the adjusting rotary rod 5 respectively, and are used to convert the movement of the locking member in the radial direction of the filter element base 2 into the rotation of the adjusting rotary rod 5, and convert the rotation of the adjusting rotary rod 5 into the movement of the locking member in the radial direction of the filter element base 2, thereby achieving the conversion between the rotation of the adjusting rotary rod 5 and the extension and contraction of the locking member; the specific structure and arrangement position of the connecting rod 4 need to be determined according to the structure and size of the locking member, and the structure, size and arrangement position of the adjusting rotary rod 5 in actual production;

[0041] The adjusting rotary rod 5 is arranged on the bottom plate of the filter element base 2 and is rotatably connected with the filter element base 2 through a rotating shaft 51; the rotating shaft 51 can be arranged independently from the adjusting rotary rod 5 or integrally with the adjusting rotary rod 51; the adjusting part of the rotating shaft 51 protrudes outward from the filter element base cover 8, so that the user can rotate the adjusting rotary rod 5 without disassembling the filter element base cover 8, thereby simplifying the operation of assembling and disassembling the filter element; it should be noted that the adjusting part of the rotating shaft 51 protrudes outward from the filter element base cover 8, which can be arranged above the top plate of the filter element base cover 8 or protrude outward from the outer circumferential surface of the filter element base cover 8.

[0042] In order to facilitate the machining of the filter element base cover 8 and the assembly of the filter element base cover 8 and the rotating shaft 51, the end of the rotating shaft 51 away from the filter element base 2 is preferably provided with a knob 52 and a knob cover 53; the knob cover 53 is arranged between the top end of the rotating shaft 51 and the top plate of the filter element base cover 8 by clamping or threaded connection.

[0043] The reset member is arranged between the filter element base 2 and the adjusting rotary rod 5 and is used to drive the adjusting rotary rod 5 to extend outward in the radial direction of the filter element base 2 by the elastic reset force of the reset member after the torque at the adjusting rotary rod 5 is removed, so as to press the locking member against the filter element locking groove, thereby achieving self-locking of the filter element and ensuring stable and reliable installation of the filter element in the working state.

[0044] Please refer to Figure 2 The locking member is connected with the adjusting rotary rod 5 through the connecting rod 4, so that when the filter element is installed, the inward contraction of the locking member in the radial direction of the filter element base 2 under pressure during insertion of the filter element can be converted into the rotation of the adjusting rotary rod 5, and after the filter element is inserted in place, the locking member is driven to extend outward in the radial direction of the filter element base 2 by the reset member between the filter element base 2 and the adjusting rotary rod 5, so as to press the locking member against the filter element locking groove, thereby achieving self-locking of the filter element.

[0045] Conversely, when disassembling the filter core, only need to adjust the rotation, using the rotation of the adjusting rod 5 to drive the locking member to retract along the radial direction of the filter core base 2, so that the locking member is separated from the filter core locking groove, and then the filter core can be pulled out.

[0046] In the embodiment, both the quick assembly and disassembly of the filter core are realized, and the installation stability and reliability of the filter core are ensured through the self-locking capability.

[0047] On the basis of the above embodiment, in order to limit the movement direction of the locking member, the outer circumferential surface of the filter core base 2 is provided with a mounting groove for the locking member to pass through, one of the upper surface of the bottom plate of the filter core base 2 and the bottom surface of the locking member is provided with a sliding rail 21, and the other is provided with a sliding groove 31 which is slidingly arranged along the sliding rail 21.

[0048] Please refer to Figure 3 , the upper surface of the bottom plate of the filter core base 2 is provided with a sliding rail 21, and the bottom surface of the locking member is provided with a sliding groove 31, as shown in Figure 4 ; in order to limit the stroke of the locking member, the end of the sliding rail 21 away from the outer circumferential surface of the filter core base 2 is preferably provided with a limiting member, which can be specifically provided as a limiting boss, a sliding limiting rib 22, etc.

[0049] In the embodiment, the sliding cooperation of the sliding rail 21 and the sliding groove 31 can effectively constrain the movement direction of the locking member, and facilitate the determination of the movement stroke and installation position of the connecting rod 4 and the adjusting rod 5.

[0050] In addition, in order to limit the axial movement of the locking member, the connecting rod 4 and the adjusting rod 5, etc., a pressing plate 7 is usually arranged in the filter core mounting structure, as shown in Figure 1 .

[0051] Preferably, the axis of the rotating shaft 51 is collinear with the axis of the filter core base 2, the adjusting rod 5 is rotatably arranged at the center of the filter core base 2, the extension direction of the sliding rail 21 is parallel to the center line of the mounting groove and the vertical plane in which the rotating shaft 51 is located, so that the locking member only has a displacement component in the radial direction of the filter core base 2, and does not have a displacement component in the tangential direction of the filter core base 2, so as to simplify the movement path design of the filter core mounting structure.

[0052] On the basis of the above embodiment, the reset member includes a torsion spring 6, the torsion spring 6 is arranged on the upper surface of the bottom plate of the filter core base 2 through a torsion spring shaft 23, one end of the torsion spring 6 abuts against the adjusting rod 5, and the other end of the torsion spring 6 abuts against the filter core base 2.

[0053] It needs to be explained that since the reset member only needs to ensure that it can be driven by the adjusting rotating rod 5 to make the locking member extend outward along the radial direction of the filter element base 2 to realize the self-locking function, the reset member only needs to be able to provide elastic reset force to the adjusting rotating rod 5 in one direction of movement, so the torsional spring 6 can only abut against the adjusting rotating rod 5 without being connected with the adjusting rotating rod 5;

[0054] Of course, the torsional spring 6 can also be connected with the adjusting rotating rod 5 and / or the filter element base 2.

[0055] In the embodiment, the torsional spring 6 can accumulate elastic potential energy when the locking member retracts inward along the radial direction of the filter element base 2, and then make the locking member extend outward along the radial direction of the filter element base 2 by using the elastic reset force after the adjusting rotating rod 5 removes the external force, so as to realize the self-locking of the locking member and the filter element locking groove. The structure is simple, easy to assemble, and low in cost.

[0056] In addition, the torsional spring 6 can also be replaced by a reset spring, and the rotation of the adjusting rotating rod 5 is used to compress the reset spring to accumulate elastic potential energy.

[0057] In order to conveniently limit the stroke of the torsional spring 6, preferably, the bottom of the adjusting rotating rod 5 is provided with a first torsional spring limiting portion 54. As shown in Figure 5 , the first torsional spring limiting portion 54 can be specifically provided as a limiting column, a limiting wheel, a limiting plate, etc., and the upper surface of the filter element base 2 is provided with a second torsional spring limiting portion. As shown in Figure 3 , the second torsional spring limiting portion can be specifically provided as a limiting column, a limiting wheel, a limiting plate, etc.

[0058] Preferably, the second torsional spring limiting portion includes a horizontal limiting groove 241 and a vertical limiting rib 25, the horizontal limiting groove 241 is arranged on the horizontal limiting rib 24, the width of the horizontal limiting groove 241 is greater than the diameter of the torsional spring 6, and the horizontal limiting rib 24 and the vertical limiting rib 25 are both vertically arranged on the upper surface of the bottom plate of the filter element base 2.

[0059] At this time, the horizontal limiting rib 24 and the vertical limiting rib 25 not only can limit the stroke of the torsional spring 6, but also can be used as reinforcing ribs to enhance the structural strength of the filter element base 2.

[0060] On the basis of the above-mentioned embodiments, considering that the locking member is usually two or more in actual production, the locking members can be uniformly distributed along the circumferential direction of the filter element base 2, the adjusting rotating rod 5 is uniformly provided with a plurality of hinged points connected with the connecting rods 4 along the circumferential direction of the filter element base 2, and the hinged points are one-to-one correspondingly arranged with the locking members to meet the synchronous stretching and retracting requirements of the plurality of locking members.

[0061] On the basis of the above-mentioned embodiments, the structure of the locking member is limited, the locking member includes a locking key 3, the circular arc end of the locking key 3 is in clamping and matching with the filter element locking groove, and the rectangular end of the locking key 3 is hingedly connected with the connecting rod 4.

[0062] The locking key 3 is used for connecting with the rectangular end shape of the connecting rod 4, which is regular, convenient for processing and assembling, and the end face of the locking end which is clamped with the filter core locking groove is a circular arc face, compared with a rectangular plane, on the premise that the outer peripheral surface of the filter core base 2 is a cylindrical surface, the circular arc face design can make the distance of the locking key 3 protruding from the outer peripheral surface of the filter core base 2 be the same in each direction, which is beneficial to reducing the contraction distance of the locking key 3 in the radial direction of the filter core base 2 when unlocking; while the rectangular plane design will cause the distance of the rectangular plane of the locking key 3 protruding from the outer peripheral surface of the filter core base 2 to be different in each direction, resulting in the contraction distance required for the locking key 3 to unlock being larger, which affects the internal space design of the filter core base 2.

[0063] Preferably, the axis of the circular arc end of the locking key 3, the axis of the filter core base 2 and the axis of the rotating shaft 51 are collinear, so that the distance of the circular arc end of the locking key 3 protruding from the outer peripheral surface of the filter core base 2 is the same in each direction, which not only facilitates the processing and manufacturing of the locking key 3, but also ensures that the compression force of the locking key 3 in each direction is approximately the same in the self-locking state, avoiding the problem of local damage caused by excessive local pressure, so as to prolong the overall service life of the locking key 3.

[0064] In addition to the above-mentioned self-locking quick-mounting filter core, the utility model also provides a water purification equipment comprising the self-locking quick-mounting filter core disclosed in the above-mentioned embodiments, which comprises a water purification equipment main body and a detachable filter core, the filter core is the self-locking quick-mounting filter core disclosed in the above-mentioned embodiments, and the structure of the water purification equipment main body refers to the prior art, which will not be described herein.

[0065] It should be noted that the first and second in the first torsional spring limiting portion 54 and the second torsional spring limiting portion mentioned in the present application are only used to distinguish the different positions, and do not limit the order.

[0066] The embodiments in the description are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same and similar parts between the embodiments can be referred to each other.
