Description

Technical Field

[0001] The utility model relates to the field of water purifiers, in particular to a filter element assembly with a locking structure. Background Art

[0002] A water purifier is a device that uses a filter element to filter floating substances, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, and microorganisms in water. In order to extend the service life of the water purifier, in existing water purifiers, especially small household water purifiers, the filter element is generally a detachable filter element, so that the filter element can be replaced after the water purifier has been used for a period of time.

[0003] In order to facilitate the replacement of the filter element, a handle is often provided on the filter element. In the prior art, there is a lack of a limiting structure between the handle and the filter element, resulting in a free state of the handle relative to the filter element without external force. When the user disassembles and installs the filter element, the handle cannot be held by hand, and the handle naturally drops under the action of gravity. In order to prevent the handle from affecting the disassembly and installation of the filter element with the handle structure, the user needs to hold the handle with one hand, which brings inconvenience to the disassembly and installation of the filter element.

[0004] Moreover, in the existing filter element, it can be directly pushed into the base of the casing during installation, and the filter element lacks a locking structure, resulting in poor stability after the filter element is installed. Summary of the Utility Model

[0049] Thus, the present utility model is provided with a first locking structure 30 and a second locking structure 40, which can assist in moving the filter element 10 through the handle 102, facilitating the replacement and transfer of the filter element 10. After the filter element 10 is installed on the housing 20, when the handle 102 rotates to the first locking position, the handle 102 is locked with the housing 20 through the first locking structure 30, and the handle 102 is locked with the filter element body 101 through the second locking structure 40, realizing the relative locking between the handle 102, the filter element body 101 and the housing 20, which can not only prevent the handle 102 from affecting the disassembly and assembly of the filter element 10, but also improve the stability of the filter element 10 after installation.

[0050] That is to say, after the filter element 10 is installed in the installation position of the housing 20, to realize the locking between the filter element body 101, the handle 102 and the housing 20 by using the first locking structure 30 and the second locking structure 40, it is necessary to first unlock the second locking structure 40, and then rotate the handle 102 relative to the filter element body 101 to unlock the first locking structure 30 before the filter element 10 can be taken out.

[0051] In the embodiment of the present utility model, the first locking structure 30 includes a first locking member and a second locking member. The first locking member is arranged on the side of the handle 102 facing the housing 20, and the second locking member is arranged on the side of the housing 20 facing the handle 102; the first locking member includes a limiting portion 301, and an opening is provided on the limiting portion 301. The second locking member includes a first protrusion 302; when the first locking member cooperates with the second locking member, the limiting portion 301 is clamped with the first protrusion 302.

[0052] That is, the first locking member is arranged on the outer side of the handle 102, the second locking member is arranged on the outer side of the housing 20, and the first locking member and the second locking member are arranged corresponding to each other.

[0053] In the embodiment of the present utility model, the first locking member is integrally in the shape of an arc-shaped rib, and the limiting portion 301 is in the shape of a sector; the housing 20 is provided with an installation cavity, the installation cavity forms an installation position, and an inlet and an outlet are provided in front of and above the installation cavity; refer to Figure 2 , when the limiting portion 301 is engaged with the first protrusion 302, the opening of the limiting portion 301 faces the front and the lower part of the installation cavity of the housing 20, and the first protrusion 302 restricts the filter element 10 from moving in at least one direction among the front of the installation cavity of the housing 20, the upper oblique direction of the installation cavity of the housing 20, or the lower oblique direction of the installation cavity of the housing 20.

[0054] Specifically, the movement direction of the filter element 10 restricted by the first protrusion 302 is determined according to the specific shape of the limiting portion 301 and the specific orientation of the opening of the limiting portion 301.

[0055] It should be noted that the first locking structure 30 can be applicable to the case where the filter element 10 is installed by being pushed into the installation cavity of the housing 20. At this time, the first locking structure 30 can restrict the filter element 10 from being horizontally pulled out of the installation cavity of the housing 20 during use. In this case, the bottom of the installation cavity is a flat structure; the first locking structure 30 can also be applicable to the case where the filter element 10 is inserted into the installation cavity of the housing 20 in an inclined downward direction and then rotated to the vertical direction for installation. At this time, the first locking structure 30 can restrict the filter element 10 from rotating obliquely downward during use. In this case, an installation groove 60 is provided at the bottom of the installation cavity.

[0056] Specifically, the first protrusion 302 is cylindrical, the limiting portion 301 is engaged with the first protrusion 302 by rotating forward following the handle 102, and the limiting portion 301 can be disengaged from the second protrusion 403 by rotating backward following the handle 102.

[0057] Specifically, the first locking member is integrally formed with the handle 102, or the first locking member and the handle 102 are separately formed and then connected into one body by processes such as welding and gluing.

[0058] In the embodiment of the present utility model, the second locking structure 40 includes a third locking member and a fourth locking member. The third locking member is arranged on the side of the handle 102 facing the filter element body 101, and the fourth locking member is arranged on the side of the filter element body 101 facing the handle 102; the third locking member includes a card slot 401 and a first guiding inclined surface 402, the card slot 401 and the first guiding inclined surface 402 are connected to each other, and the fourth locking member includes a second protrusion 403; when the third locking member and the fourth locking member are engaged, the card slot 401 is engaged with the second protrusion 403 through the first guiding inclined surface 402.

[0059] That is to say, the third locking member is arranged on the inner side surface of the handle 102, the fourth locking member is arranged on the outer side surface of the filter element body 101, and the third locking member and the fourth locking member are arranged corresponding to each other.

[0060] Specifically, the second protrusion 403 is a cylindrical protrusion, and the end of the second protrusion 403 has an arc transition for cooperating with the first guiding inclined surface 402, so as to facilitate the clamping connection of the clamping groove 401 with the second protrusion 403 through the first guiding inclined surface 402.

[0061] More specifically, the first guiding inclined surface 402 is arranged at the inlet and outlet positions of the clamping groove 401.

[0062] Certainly, in other embodiments, the third locking member includes the second protrusion 403, the fourth locking member includes the clamping groove 401 and the first guiding inclined surface 402, and the clamping groove 401 is connected to the first guiding inclined surface 402; when the third locking member cooperates with the fourth locking member, the clamping groove 401 is clamped with the second protrusion 403 through the first guiding inclined surface 402.

[0063] That is to say, the specific setting positions of the clamping groove 401 and the second protrusion 403 are such that the handle 102 and the filter element body 101 can be clamped at the first locking position through the clamping groove 401 and the second protrusion 403; the clamping groove 401 can be arranged on the handle 102, or the clamping groove 401 can be arranged on the filter element body 101; the second protrusion 403 can be arranged on the handle 102, or the second protrusion 403 can be arranged on the filter element body 101.

[0064] In the embodiment of the present utility model, the filter element assembly with a locking structure further includes a third locking structure 50, and the third locking structure 50 includes a fifth locking member and a sixth locking member. The fifth locking member is arranged on the side surface of the handle 102 facing the filter element body 101, and the sixth locking member is arranged on the side surface of the filter element body 101 facing the handle 102; the fifth locking member includes a first buckle 501, the sixth locking member includes a second buckle 502, and a second guiding inclined surface 503 is arranged on the second buckle 502; when the fifth locking member cooperates with the sixth locking member, the first buckle 501 is clamped with the second buckle 502 through the second guiding inclined surface 503.

[0065] In the embodiment of the present utility model, when the handle 102 rotates relative to the filter element body 101 to the second locking position, the handle 102 is locked with the filter element body 101 through the third locking structure 50.

[0066] In the embodiment of the present utility model, the handle 102 rotates between the first locking position and the second locking position, and the rotation range of the handle 102 is 0-90°; when the handle 102 is horizontally placed, the handle 102 is in the first locking position; when the handle 102 is vertically placed, the handle 102 is in the second locking position.

[0067] Specifically, the longitudinal section of the second buckle 502 is in an "L" shape, and when the handle 102 is placed horizontally, the transverse section of the first buckle 501 is in an "L" shape; thus, when the handle 102 is placed vertically, the first buckle 501 and the second buckle 502 are hooked and cooperated with each other.

[0068] More specifically, a stop block 504 is further provided on the second buckle 502. The stop block 504 is provided at the end of the second buckle 502 close to the second locking member. The stop block 504 can prevent the handle 102 from continuing to rotate in the direction away from the fourth locking member after the fifth locking member and the sixth locking member are cooperated, thereby restricting the rotation angle of the handle 102.

[0069] Of course, in other embodiments, the sixth locking member includes the first buckle 501, the fifth locking member includes the second buckle 502, and a second guiding inclined surface 503 is provided on the second buckle 502; when the fifth locking member and the sixth locking member are cooperated, the first buckle 501 is clamped with the second buckle 502 through the second guiding inclined surface 503.

[0070] That is to say, the specific setting positions of the first buckle 501 and the second buckle 502 are such that the handle 102 and the filter element body 101 can be clamped at the second locking position through the clamping of the first buckle 501 and the second buckle 502; the first buckle 501 can be provided on the handle 102, and the first buckle 501 can also be provided on the filter element body 101; the second buckle 502 can be provided on the handle 102, and the second buckle 502 can also be provided on the filter element body 101.

[0071] In the embodiment of the present utility model, a third locking member is provided in the middle of the handle 102, and a fifth locking member is provided at least at one end of the handle 102.

[0072] Preferably, a third locking member is provided in the middle of the handle 102, and fifth locking members are provided at both ends of the handle 102, so that both ends of the handle 102 can be clamped with the filter element body 101, making the force on the handle 102 uniform, avoiding deformation of the handle 102 due to uneven force after long-term use, and extending the service life of the handle 102.

[0073] In the embodiment of the present utility model, the filter element further includes a connecting structure 70. The filter element body 101 is rotatably connected with the handle 102 through the connecting structure 70; the connecting structure 70 includes a rotating shaft 701. One end of the handle 102 is rotatably connected with one side of the filter element body 101 through a rotating shaft 701, and the other end of the handle 102 is rotatably connected with the other side of the filter element body 101 through another rotating shaft 701.

[0074] Specifically, the connecting structure 70 further includes a mounting hole 702 that cooperates with the rotating shaft 701. The rotating shaft 701 is provided on the filter element body 101, and a mounting hole 702 that cooperates with the rotating shaft 701 is provided at a corresponding position on the handle 102, thereby realizing the rotational connection between the handle 102 and the rotating shaft 701.

[0075] It should be noted that when the mounting hole 702 is provided on the handle 102, the mounting hole 702 and the fifth locking member provided at the same end of the handle 102 are arranged in a staggered manner, and the rotating shaft 701 and the sixth locking member provided on the same side of the filter element body 101 are arranged in a staggered manner to avoid interference between the above-mentioned components; and the mounting hole 702 is provided between the fifth locking member and the first locking member, and the second buckle 502 and the rotating shaft 701 are arranged up and down along the axial direction of the filter element body 101, and the second buckle 502 is provided below the rotating shaft 701.

[0076] Of course, in other embodiments, the rotating shaft 701 is provided on the handle 102, and a mounting hole 702 that cooperates with the rotating shaft 701 is provided at a corresponding position on the filter element body 101, thereby realizing the rotational connection between the handle 102 and the rotating shaft 701.

[0077] That is to say, the specific setting positions of the rotating shaft 701 and the mounting hole 702 are such that the handle 102 and the filter element body 101 can be rotationally connected.

[0078] It should be noted that the filter element body 101 is cylindrical, and for the convenience of use, the handle 102 is in a "U" shape.

[0079] Specifically, in order for the handle 102 to rotate relative to the filter element body 101 between the first locking position and the second locking position, the inner diameter of the handle 102 is greater than the outer diameter of the filter element body 101.

[0080] It should be noted that the handle 102 can be a plastic handle 102 or a metal handle 102, and it is in a flat strip shape. Since it is necessary to pull the handle 102 when unlocking the third locking member and the fourth locking member, the handle 102 needs to undergo slight deformation at this time, so that the second protrusion 403 disengages from the card slot 401 on the handle 102 through the first guiding inclined surface 402.

[0081] In the embodiment of the present utility model, a pulling portion 80 is provided on the handle 102. When the handle 102 is locked with the filter element body 101 through the second locking structure 40, the pulling portion 80 protrudes from the top of the filter element body 101.

[0082] Specifically, the inner side of the handle 102 is set as the first side, the outer side of the handle 102 is set as the second side, the side of the handle 102 facing the second locking member is set as the third side, the third side is arranged between the first side and the second side, the side of the handle 102 away from the second locking member is set as the fourth side, and the fourth side is arranged between the first side and the second side; the pulling part 80 is arranged on the fourth side of the handle 102 and extends along the length direction of the handle 102, so that the pulling part 80 does not affect the rotation of the handle 102 between the first locking position and the second locking position, and the pulling part 80 does not affect the cooperation and unlocking of the second locking structure 40 and the third locking structure 50 either.

[0083] More specifically, a convex part is arranged on the inner side of the pulling part 80, and the convex part is the force application position for the user to operate.

[0084] Since when the handle 102 is placed horizontally, the handle 102 is flush with the filter element body 101, the user can pull the handle 102 through the pulling part 80, and there is a force application point during the operation of the handle 102, which is beneficial to use.

[0085] The specific use process of the present utility model is as follows:

[0086] After the lower end of the filter element body 101 is inserted into the installation groove 60 of the machine shell 20, when the handle 102 is locked at the first locking position, the user pushes the handle 102 to rotate towards the fourth locking member close to the filter element body 101. The handle 102 rotates to the first locking position, and the limiting part 301 on the handle 102 catches the first protrusion 302 on the machine shell 20. And the user presses the handle 102, so that the second protrusion 403 on the filter element body 101 enters the card slot 401 on the handle 102 through the first guiding inclined surface 402, thereby realizing the clamping connection between the handle 102 and the machine shell 20 at the first locking position and the clamping connection between the handle 102 and the filter element body 101 at the first locking position; thus, since the handle 102 is limited by the machine shell 20 and the filter element body 101, the upper end of the filter element body 101 is fixed. Also, since the lower end of the filter element body 101 is fixed by the installation groove 60, both the upper and lower ends of the filter element body 101 are limited, so that the filter element body 101 cannot move forward into the installation cavity, improving the stability of the filter element body 101 after installation.

[0087] When the handle 102 is unlocked at the first locking position, the user pulls the handle 102, and the user pushes the handle 102 to rotate in the direction away from the fourth locking member of the filter element body 101, so that the second protrusion 403 on the filter element body 101 disengages from the card slot 401 on the handle 102 through the first guiding inclined surface 402. At the same time, the limiting portion 301 on the handle 102 disengages from the first protrusion 302 on the housing 20, realizing the unlocking of the first locking structure 30 and the unlocking of the second locking structure 40. In this way, the user can lift the filter element body 101 upward from the installation groove 60 of the housing 20 by hand, and the filter element body 101 disengages from the housing 20 from above the installation cavity, thereby realizing the separation of the filter element body 101 and the handle 102 from the housing 20.

[0088] When the handle 102 is locked at the second locking position, the user pushes the handle 102 to rotate in the direction of the sixth locking member of the filter element body 101, and the handle 102 rotates to the second locking position, so that the first buckle 501 on the handle 102 enters into the second buckle 502 on the filter element body 101 through the second guiding inclined surface 503, thereby realizing the clamping connection of the handle 102 and the filter element body 101 at the second locking position.

[0089] When the handle 102 is unlocked at the second locking position, the user reversely pushes the handle 102 to rotate in the direction of the second locking member of the filter element body 101, so that the first buckle 501 on the handle 102 disengages from the second buckle 502 on the filter element body 101 through the second guiding inclined surface 503, realizing the unlocking of the third locking structure 50.

[0090] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.
