Description

Technical Field

[0001] The present application relates to the technical field of water purification, and particularly relates to an installation structure of an elastic reset member and a filtering device. Background Art

[0002] A filtering device is a device that filters and purifies raw water through a filter element to meet the drinking water standard. Among them, the filter element in the filtering device generally has a certain service life, and users need to regularly replace the filter element that has reached the service life. Therefore, it is required that the installation structure of the filter element is convenient to disassemble on the one hand and is firmly and reliably installed on the other hand.

[0003] Currently, the filtering devices on the market generally lock the filter element on the casing through an installation structure of an elastic reset member. The installation structure of the elastic reset member includes a locking member and an elastic reset member. The locking member is rotatably arranged on the casing, and the locking member can rotate to switch between a locking position where it cooperates with the filter element and an unlocking position where it disengages from the filter element. One end of the elastic reset member abuts against the casing, and the other end of the elastic reset member abuts against the locking member. The elastic reset member is used to drive the locking member to reset from the unlocking position to the locking position. However, since the connection between the elastic reset member and the casing and the connection between the elastic reset member and the locking member are both abutting connections, the problem that the elastic reset member disengages from the locking member easily occurs during use, and the connection reliability is poor.

[0034] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are regarded as exemplary rather than restrictive in nature.

[0035] See Figures 1-7 , which shows an elastic reset member installation structure of a preferred embodiment of the present utility model, including:

[0036] An installation base 1, and the installation base 1 is provided with a first hanging portion 111;

[0037] The locking member 2 is rotatably arranged on the mounting base 1. The locking member 2 is used to lock the filter element 4 on the mounting base 1. The locking member 2 is provided with a second hanging portion 21;

[0038] The elastic reset member 3 has a first hook 31 and a second hook 32 at both ends respectively. The first hook 31 is hung on the first hanging portion 111 to connect the elastic reset member 3 with the mounting base 1. The second hook 32 is hung on the second hanging portion 21 to connect the elastic reset member 3 with the locking member 2. The elastic reset member 3 is used to provide a driving force for the locking member 2 so that the locking member 2 maintains the state of locking the filter element 4.

[0039] In the elastic reset member mounting structure of the present utility model, since the mounting base 1 is provided with the first hanging portion 111 and the locking member 2 is provided with the second hanging portion 21, and the elastic reset member 3 has the first hook 31 and the second hook 32 at both ends respectively, and the first hook 31 is hung on the first hanging portion 111, the elastic reset member 3 is hung with the mounting base 1, restricting the elastic reset member 3 from detaching from the mounting base 1 during the rotation of the locking member 2, improving the connection stability and reliability between the elastic reset member 3 and the mounting base 1. At the same time, the second hook 32 is hung on the second hanging portion 21, so that the elastic reset member 3 is hung with the locking member 2, restricting the elastic reset member 3 from detaching from the locking member 2 during the rotation of the locking member 2, improving the connection stability and reliability between the elastic reset member 3 and the locking member 2. In addition, during installation, directly hanging the first hook 31 on the first hanging portion 111 and hanging the second hook 32 on the second hanging portion 21 can realize the installation of the elastic reset member 3 at the set position. The installation operation is simple and the installation efficiency is high. In addition, during use, by applying a rotational force to the locking member 2 in the direction of stretching the elastic reset member 3, the locking member 2 can be disconnected from the filter element 4 to unlock the filter element 4. After releasing the locking member 2, the locking member 2 can be reset to the state of cooperating with the filter element 4 under the action of the driving force to lock the filter element 4, thereby reliably fixing the filter element 4 on the mounting base 1. The disassembly and assembly operation of the filter element 4 is simple and convenient, and the disassembly and assembly efficiency is high, facilitating the replacement of the filter element 4. In addition, the elastic reset member 3 only deforms when the locking member 2 needs to rotate and does not deform when the locking member 2 does not rotate, so the service life is longer.

[0040] See Figures 4-5, in one embodiment, the first hanging portion 111 is provided with a hanging main body 1111 and a limiting main body 1112. The inner end of the hanging main body 1111 is connected to the mounting base 1. The first hook 31 is disposed around the hanging main body 1111 so that the first hook 31 can be hung on the first hanging portion 111. The limiting main body 1112 is disposed at the outer end of the hanging main body 1111. The limiting main body 1112 protrudes relative to the surface of the hanging main body 1111 where it is connected to the first hook 31. The limiting main body 1112 can abut against the first hook 31 to limit the first hook 31 on the hanging main body 1111. In this way, during installation, by hanging the first hook 31 on the hanging main body 1111, the elastic reset member 3 can be connected to the mounting base 1. The installation operation is simple and more convenient. At the same time, since the inner end of the hanging main body 1111 is connected to the mounting base 1 and the outer end of the hanging main body 1111 is connected to the limiting main body 1112, the mounting base 1 and the limiting main body 1112 can be used to limit the first hook 31 to prevent the first hook 31 from detaching from the hanging main body 1111, so that the elastic reset member 3 and the mounting base 1 are reliably connected together with higher connection stability.

[0041] In other embodiments, the first hanging portion 111 may also be provided with a perforation for the first hook 31 to pass through, so that the first hook 31 can be hung on the first hanging portion 111, and the elastic reset member 3 and the mounting base 1 can also be reliably connected together.

[0042] See Figure 4 and Figure 7 , in one embodiment, the second hanging portion 21 has a hanging hole 211 for the second hook 32 to pass through so that the second hook 32 can be hung on the second hanging portion 21. In this way, by passing the second hook 32 through the hanging hole 211 and hanging it on the second hanging portion 21, the elastic reset member 3 and the locking member 2 can be reliably connected together. The installation operation is simple and more convenient.

[0043] Specifically, both ends in the length direction of the second hanging portion 21 are connected to the locking member 2, and the second hanging portion 21 and the locking member 2 enclose the hanging hole 211.

[0044] In other embodiments, the second hanging portion 21 may specifically be provided with a hanging main body 1111 and a limiting main body 1112. The inner end of the hanging main body 1111 is connected to the locking member 2, and the outer end of the hanging main body 1111 is connected to the limiting main body 1112. The second hook 32 is hung on the hanging main body 1111, and the second hook 32 is limited by the locking member 2 and the limiting main body 1112 to be restricted on the hanging main body 1111, ensuring that the elastic reset member 3 and the locking member 2 are reliably connected together.

[0045] SeeFigure 4 and Figure 6 In one embodiment, the elastic reset member 3 further includes a spring 33. One end of the spring 33 extends outwardly and bends to form a first hook 31, and the other end of the spring 33 extends outwardly and bends to form a second hook 32. The spring 33 has good elastic performance, which can enable the elastic reset member 3 to reliably maintain the state of applying a driving force to the locking member 2, so that the locking member 2 can be reset smoothly and durably.

[0046] In other embodiments, a shrapnel can be used to replace the above-mentioned spring 33, which can also apply a driving force to the locking member 2 to ensure that the locking member 2 can be reset.

[0047] See Figures 2-4 and Figure 7 In one embodiment, the locking member 2 has a locking groove 22 for cooperating with a locking portion 41 on the filter element 4 to lock the filter element 4 to the mounting base 1. By the cooperation of the locking groove 22 and the locking portion 41, the contact area between the locking member 2 and the filter element 4 is increased, which can improve the connection stability and reliability between the locking member 2 and the filter element 4, and thus the filter element 4 can be reliably locked to the mounting base 1.

[0048] In other embodiments, among the locking member 2 and the filter element 4, one is provided with a first locking protrusion, and the other is provided with a second locking protrusion. The second locking protrusion cooperates with the first locking protrusion to also realize the locking of the filter element 4.

[0049] See Figures 2-3 and Figure 5 In one embodiment, the mounting base 1 is provided with a first positioning inclined surface 112, and the locking member 2 is provided with a second positioning inclined surface 23. The second positioning inclined surface 23 abuts against the first positioning inclined surface 112 to limit the rotation of the locking member 2, so that the locking member 2 is maintained in the state of locking the filter element 4, thereby realizing the reliable locking of the filter element 4 and improving the structural stability and reliability.

[0050] See Figures 2-3 and Figure 5 In one embodiment, the locking member 2 is further provided with an arc surface 24. The arc surface 24 is connected to the second positioning inclined surface 23 and is arranged around the rotation center line of the locking member 2. The arc surface 24 is movably engaged with the first positioning inclined surface 112 to guide the rotation of the locking member 2. Thus, during the rotation of the locking member 2, the first positioning inclined surface 112 is separated from the second positioning inclined surface 23 as the locking member 2 rotates. At the same time, the arc surface 24 is movably engaged with the second positioning inclined surface 23 to guide the locking member 2 to rotate in the direction of stretching the elastic reset member 3 or in the direction of the elastic reset member 3 resetting, playing a role of rotation guiding, making the rotation of the locking member 2 smoother, and thus improving the smoothness of the locking and unlocking operations of the filter element 4.

[0051] See Figures 4-5 and Figure 7 , in one embodiment, the mounting base 1 is provided with a first connecting protrusion 113;

[0052] The locking member 2 has a first connecting hole 25, and the first connecting hole 25 is rotatably engaged with the first connecting protrusion 113 so that the locking member 2 can rotate relative to the mounting base 1. In this way, during installation, by engaging the first connecting hole 25 with the first connecting protrusion 113, the locking member 2 can be rotatably mounted on the mounting base 1. The installation operation is simple, the installation efficiency is high, and the rotation connection structure composed of the first connecting protrusion 113 and the first connecting hole 25 is simple and practical, with low cost.

[0053] In one embodiment, the mounting base 1 is further provided with a second connecting protrusion 114, and the second connecting protrusion 114 is arranged around the first connecting protrusion 113;

[0054] The locking member 2 further has a second connecting hole, the second connecting hole is arranged around the first connecting hole 25, and the second connecting hole is rotatably engaged with the second connecting protrusion 114. By engaging the second connecting hole with the second connecting protrusion 114, the rotation stability of the locking member 2 can be improved, making the locking member 2 rotate more smoothly.

[0055] See Figures 1-4 , in one embodiment, the mounting base 1 includes:

[0056] A mounting main body 11, the mounting main body 11 has a receiving groove 115 and a mounting opening. The receiving groove 115 receives the locking member 2 and at least a part of the elastic reset member 3. The mounting opening is oppositely arranged with the bottom wall of the receiving groove 115, the mounting opening communicates with the receiving groove 115, the mounting opening allows the locking member 2 and the elastic reset member 3 to enter and exit the receiving groove 115, and the inner end of the first connecting protrusion 113 is connected to the bottom wall of the receiving groove 115;

[0057] The cover plate 12 is provided on the mounting body 11. The cover plate 12 covers the mounting opening to limit the locking member 2 and the elastic reset member 3 on the mounting body 11. The cover plate 12 has a positioning hole 121, and the positioning hole 121 cooperates with the outer end of the first connecting protrusion 113. In this way, during installation, the second hook 32 is hooked to the second hooking portion 21. By arranging the locking member 2 in the receiving groove 115 and connecting it to the first connecting protrusion 113, and at the same time hooking the first hook 31 to the first hooking portion 111, and then installing the cover plate 12 on the mounting body 11, the installation of the locking member 2 and the elastic reset member 3 can be completed. The cover plate 12 and the bottom wall of the receiving groove 115 jointly limit the locking member 2 and the elastic reset member 3, restricting the locking member 2 and at least part of the elastic reset member 3 in the receiving groove 115, improving the connection stability and reliability between the locking member 2 and the mounting base 1. At the same time, it also improves the connection stability and reliability between the elastic reset member 3 and the locking member 2 and between the elastic reset member 3 and the mounting base 1. In addition, during installation, by the cooperation of the positioning hole 121 and the outer end of the first connecting protrusion 113, the installation positioning of the cover plate 12 can be realized, facilitating the quick and correct installation of the cover plate 12 on the mounting body 11 and improving the installation efficiency.

[0058] In one embodiment, the mounting body 11 has a mounting cavity that penetrates the top of the mounting body 11 and forms an opening;

[0059] The filter element 4 is detachably provided in the mounting cavity, and the filter element 4 vertically enters and exits the mounting cavity through the opening;

[0060] Both the locking member 2 and the elastic reset member 3 are located on the side close to the opening. The locking member 2 cooperates with the top of the filter element 4 to reliably lock the filter element 4 in the mounting cavity, making the filter element 4 and the mounting base 1 reliably fixed together, with higher structural stability and reliability.

[0061] In one embodiment, the mounting body 11 is provided with a plurality of threaded holes 116, and the plurality of threaded holes 116 are arranged around the receiving groove 115;

[0062] The cover body is provided with a plurality of third connecting holes 122, and each third connecting hole 122 is connected to a threaded hole 116 by a screw one by one to reliably connect the mounting body 11 and the cover plate 12 together.

[0063] In other embodiments, the mounting body 11 and the cover plate 12 can also be connected together by any one or a combination of clamping methods, magnetic attraction cooperation methods, etc.

[0064] See Figures 1-4 , which shows that a filtering device provided by a preferred embodiment of the present invention includes a filter element 4 and the above-mentioned elastic reset member mounting structure.

[0065] The filtering device of the present invention, due to the adoption of the above-mentioned elastic return member installation structure, can also limit the elastic return member 3 from being separated from the installation base 1 during the rotation of the locking member 2, thereby improving the connection stability and reliability of the elastic return member 3 and the installation base 1. At the same time, it can also limit the elastic return member 3 from being separated from the locking member 2 during the rotation of the locking member 2, thereby improving the connection stability and reliability of the elastic return member 3 and the locking member 2.

[0066] In one embodiment, a handle 42 is rotatably provided on the top of the filter element 4, and the handle 42 has a first position vertically placed on the top of the filter element 4, so that the user can pull the filter element 4 out of the installation cavity by carrying the handle 42, and the handle 42 also has a second position horizontally placed on the top of the filter element 4, so that the handle 42 can be stored and placed on the filter element 4, and the handle 42 is rotated to switch between the first position and the second position, and the handle 42 is provided with a locking portion 41, and when the filter element 4 is arranged in the installation cavity and the handle 42 is in the second position, the locking portion 41 cooperates with the locking groove 22 to lock the filter element 4 in the installation cavity;

[0067] The locking member 2 is rotated by the locking portion 41, so that when the filter element 4 is inserted into the installation cavity, the locking portion 41 can be abutted against the locking member 2 to push the locking member 2 to rotate in the direction of stretching the elastic return member 3 until the locking portion 41 is engaged with the locking groove 22. In the process of pulling the filter element 4 out of the installation cavity, the filter element 4 is lifted by the carrying handle 42, and the locking portion 41 pushes up the locking member 2 until the locking portion 41 is disengaged from the locking groove 22. The filter element 4 can be unlocked and removed by lifting the handle 42 with one hand, which saves more effort. At the same time, the locking member 2 can be driven to rotate by the handle 42, so that the locking member 2 can be rotated during the process of installing the filter element 4, so that the locking member 2 avoids the locking portion 41, and the locking member 2 can be rotated to unlock the filter element 4 during the process of pulling out the filter element 4, thereby improving the utilization rate of the handle 42 and making the replacement of the filter element 4 more convenient.
