Description

Technical Field

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

[0002] A water purifier is a device that filters floating substances, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, and microorganisms in water through a filter element. 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] In addition, the existing filter element can be directly pushed into the base of the casing during installation, and the filter element lacks a locking structure, so the stability of the filter element after installation is poor. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a filter element assembly with an installation structure, which is provided with a first locking member and a second locking member. During installation, the filter element is inserted obliquely downward into the installation position and connected to the first locking member, and then the filter element rotates relative to the casing to the vertical direction following the first locking member, and the handle rotates relative to the filter element body to the first locking position and is locked with the casing through the second locking member; thus, when unlocking, it is necessary to first rotate the handle in the opposite direction to unlock the second locking member, and then rotate the filter element in the opposite direction to unlock the first locking member, which improves the stability of the filter element installation.

[0057] The present utility model is provided with a first locking member 30 and a second locking member 40. During installation, after the filter element 20 is inserted obliquely downward into the installation position and connected to the first locking member 30, the filter element 20 rotates relative to the casing 10 to the vertical direction following the first locking member 30, and the handle 202 rotates relative to the filter element body 201 to the first locking position and is locked to the casing 10 through the second locking member 40; thus, when unlocking, it is necessary to first rotate the handle 202 in the reverse direction to unlock the second locking member 40, and then rotate the filter element 20 in the reverse direction to unlock the first locking member 30, which increases the stability of the installation of the filter element 20, and the disassembly and assembly of the above filter element 20 only require rotating the filter element 20 and rotating the handle 202, and the operation is simple.

[0058] In an embodiment of the present utility model, the filter element 20 further includes a third locking member 203 and a fourth locking member 204. The third locking member 203 is relatively fixedly connected to the lower part of the filter element body 201, and the first locking member 30 cooperates with the third locking member 203. The fourth locking member 204 is relatively fixedly connected to the outside of the handle 202, and the second locking member 40 cooperates with the fourth locking member 204.

[0059] In an embodiment of the present utility model, the first locking member 30 includes a base 301, a sliding member 302, and an elastic member 303. A first card slot 304 is provided on the base 301, a second card slot 305 is provided on the sliding member 302, the sliding member 302 is slidably connected to the base 301, one end of the elastic member 303 abuts against the base 301, and the other end of the elastic member 303 abuts against the sliding member 302; the third locking member 203 includes a tooth; when the elastic member 303 drives the sliding member 302 to move along the first direction so that the first card slot 304 and the second card slot 305 are aligned with each other, the tooth can be inserted into the first card slot 304 and the second card slot 305; when the filter element 20 rotates relative to the casing 10 to the vertical direction following the first locking member 30, the casing 10 abuts against the sliding member 302 and drives the sliding member 302 to move along the second direction so that the first card slot 304 and the second card slot 305 are misaligned, and the sliding member 302 clamps the tooth; the first direction and the second direction are opposite directions.

[0060] In the embodiment of the present utility model, a chute 306 is provided on the base 301. The sliding member 302 is slidably connected to the base 301 through the chute 306. One end of the chute 306 is provided with a notch 307, and the other end of the chute 306 is provided with a first limiting portion 308; when the sliding member 302 moves along the first direction, the first end of the sliding member 302 extends out of the base 301 from the notch 307; when the sliding member 302 moves along the second direction, the second end of the sliding member 302 abuts against the first limiting portion 308.

[0061] Specifically, the elastic member 303 is a spring or a rubber column.

[0062] More specifically, the first direction is the direction extending out of the notch 307 along the axial direction of the chute 306; the number of the first clamping grooves 304 and the second clamping grooves 305 can be one, two or more, subject to the cooperation between the first locking member 30 and the third locking member 203; the shape of the first teeth is adapted to the first clamping grooves 304 and the second clamping grooves 305, subject to the cooperation between the first locking member 30 and the third locking member 203.

[0063] It should be noted that the caliber of the notch 307 is smaller than the maximum outer diameter of the sliding member 302, and the notch 307 also has a limiting effect on the sliding member 302. By controlling the caliber of the notch 307 and the elastic force of the elastic member 303, the length of the sliding member 302 extending out of the chute 306 is controlled, so that when the sliding member 302 is driven by the elastic member 303 to extend out of the chute 306, the first clamping groove 304 and the second clamping groove 305 are just aligned; by controlling the dimensions of the first clamping groove 304, the second clamping groove 305 and the first limiting portion 308, when the first locking member 30 and the filter element 20 are rotated together to the vertical state, the housing 10 abuts against the end of the sliding member 302 extending out of the chute 306, and the housing 10 pushes the sliding member 302 backward, and the length of the housing 10 pushing the sliding member 302 backward can enable the sliding member 302 to clamp the teeth.

[0064] It should be noted that the base 301 can be integrally formed, and the above chute 306 is directly opened on the base 301; of course, the base 301 can also be formed separately. Refer to Figure 4 , the base 301 is formed by buckling an upper split body and a lower split body. The first clamping groove 304 is arranged on the upper split body, the chute 306 is arranged on the lower split body, and the sliding member 302 and the elastic member 303 are both arranged between the upper split body and the lower split body. In this way, the manufacturing difficulty and the assembly difficulty of the base 301 can be reduced.

[0065] It can be seen that when the first locking member 30 rotates to an inclined state, the elastic member 303 is not subjected to a force in the second direction, the first card slot 304 is aligned with the second card slot 305, and the filter element 20 can be inserted obliquely downward into the installation position and connected to the first locking member 30; when the filter element 20 rotates relative to the housing 10 in the reverse direction to the vertical direction following the first locking member 30, the sliding member 302 extending from the end of the first locking member 30 is squeezed by the housing 10, the sliding member 302 moves along the second direction, and the first card slot 304 is misaligned with the second card slot 305 to clamp the card teeth, so that the first locking member 30 and the third locking member 203 are matched.

[0066] In the embodiment of the present utility model, the filter element assembly with the installation structure further includes a first connecting member 50. The first locking member 30 is rotatably connected to the lower part of the housing 10 through the first connecting member 50; the filter element 20 further includes a second connecting member 205, and the handle 202 is rotatably connected to the filter element body 201 through the second connecting member 205.

[0067] Specifically, the first connecting member 50 includes a first rotating shaft. The first rotating shaft is arranged on the first locking member 30, and a first installation hole matching with the first rotating shaft is correspondingly arranged at a corresponding position on the housing 10; the second connecting member 205 includes a second rotating shaft. The second rotating shaft is arranged on the filter element body 201, and a second installation hole matching with the second rotating shaft is correspondingly arranged at a corresponding position on the handle 202.

[0068] Or, the first rotating shaft is arranged on the housing 10, and a first installation hole matching with the first rotating shaft is correspondingly arranged at a corresponding position on the first locking member 30; the second rotating shaft is arranged on the handle 202, and a second installation hole matching with the second rotating shaft is correspondingly arranged at a corresponding position on the filter element body 201.

[0069] In the embodiment of the present utility model, the second locking member 40 includes a first protrusion 401, the fourth locking member 204 includes a second limiting portion 2041, and an opening is arranged on the second limiting portion 2041; the housing 10 is provided with an installation cavity 101, the installation cavity 101 forms an installation position, and an inlet and an outlet are arranged in front of the installation cavity 101 and above the installation cavity 101; when the fourth locking member 204 rotates with the handle 202 to cooperate with the second locking member 40, the second limiting portion 2041 is clamped with the first protrusion 401, and the first protrusion 401 restricts the filter element 20 from moving in at least one direction among the front of the installation cavity 101, the upper oblique direction of the installation cavity 101, or the lower oblique direction of the installation cavity 101.

[0070] In the embodiment of the present utility model, the fourth locking member 204 is integrally in an arc-shaped rib shape, the second limiting portion 2041 is in a fan shape, and the first protrusion 401 is in a cylindrical shape.

[0071] Refer to Figure 3, when the handle 202 rotates relative to the filter element body 201 to the first locking position, the handle 202 is in a horizontal state, the second limiting portion 2041 is clamped with the first protrusion 401, the second limiting portion 2041 abuts against the rear and above the first protrusion 401, the opening of the second limiting portion 2041 faces the front and below the first protrusion 401, and the first protrusion 401 restricts the movement of the filter element 20 in at least one of the directions of the front of the installation cavity 101 of the machine shell 10, the obliquely upper part of the installation cavity 101 of the machine shell 10, or the obliquely lower part of the installation cavity 101 of the machine shell 10.

[0072] Refer to Figure 4 , when the handle 202 rotates in the opposite direction relative to the filter element body 201 away from the first locking position, for example, when the handle 202 rotates from the horizontal state to the vertical state in the opposite direction relative to the filter element body 201, the second limiting portion 2041 abuts against the front and above the first protrusion 401, the opening of the second limiting portion 2041 faces the rear and below the first protrusion 401, the filter element 20 can move in at least one of the directions of the front of the installation cavity 101 of the machine shell 10, the obliquely upper part of the installation cavity 101 of the machine shell 10, or the obliquely lower part of the installation cavity 101 of the machine shell 10. At this time, the filter element 20 can rotate in the opposite direction relative to the machine shell 10 following the first locking member 30 until the sliding member 302 pops out, the first locking member 30 is unlocked, the first locking member 30 is disengaged from the second locking member 40, and the user can take out the filter element 20 from the direction inclined upward relative to the installation cavity 101 of the machine shell 10.

[0073] Specifically, the movement direction of the filter element 20 restricted by the first protrusion 401 is determined according to the specific shape of the second limiting portion 2041 and the specific orientation of the opening of the second limiting portion 2041.

[0074] Specifically, the fourth locking member 204 is integrally formed with the handle 202, or the fourth locking member 204 is separately formed from the handle 202 and then connected into one body by processes such as welding and gluing.

[0075] In the embodiment of the present invention, the filter element 20 further includes a fifth locking member 206 and a sixth locking member 207 that cooperate with each other. The fifth locking member 206 is relatively fixedly connected to the inner side of the handle 202, and the sixth locking member 207 is relatively fixedly connected to the outer side of the filter element body 201; the fifth locking member 206 includes a third card slot 2061 and a first guiding inclined surface 2062, and the third card slot 2061 is connected to the first guiding inclined surface 2062. The sixth locking member 207 includes a second protrusion 2071; when the fifth locking member 206 cooperates with the sixth locking member 207, the third card slot 2061 is clamped with the second protrusion 2071 through the first guiding inclined surface 2062.

[0076] Specifically, the second protrusion 2071 is a cylindrical protrusion, and the end of the second protrusion 2071 has an arc transition for cooperating with the first guiding inclined surface 2062, so as to facilitate the engagement of the third card slot 2061 with the second protrusion 2071 through the first guiding inclined surface 2062.

[0077] More specifically, the first guiding inclined surface 2062 is provided at the inlet and outlet positions of the third card slot 2061.

[0078] Certainly, in other embodiments, the fifth locking member 206 includes the second protrusion 2071, the sixth locking member 207 includes the third card slot 2061 and the first guiding inclined surface 2062, and the third card slot 2061 is connected to the first guiding inclined surface 2062; when the fifth locking member 206 cooperates with the sixth locking member 207, the third card slot 2061 is engaged with the second protrusion 2071 through the first guiding inclined surface 2062.

[0079] That is to say, the specific setting positions of the third card slot 2061 and the second protrusion 2071 are such that the handle 202 and the filter element body 201 can be locked at the first locking position through the engagement of the third card slot 2061 and the second protrusion 2071; the third card slot 2061 can be provided on the handle 202, and the third card slot 2061 can also be provided on the filter element body 201; the second protrusion 2071 can be provided on the handle 202, and the second protrusion 2071 can also be provided on the filter element body 201.

[0080] In this way, by using the cooperation of the fifth locking member 206 and the sixth locking member 207, the handle 202 is in a fixed state relative to the filter element body 201 at the first locking position, avoiding the unlocking of the second locking member 40 and the first locking member 30 caused by the rotation of the handle 202, and increasing the stability of the installation of the filter element 20.

[0081] In the embodiment of the present utility model, the filter element 20 further includes a seventh locking member 208 and an eighth locking member 209 that cooperate with each other. The seventh locking member 208 is relatively fixedly connected to the inner side of the handle 202, and the eighth locking member 209 is relatively fixedly connected to the outer side of the filter element body 201; the seventh locking member 208 includes a first buckle 2081, the eighth locking member 209 includes a second buckle 2091, and a second guiding inclined surface 2092 is provided on the second buckle 2091; when the seventh locking member 208 cooperates with the eighth locking member 209, the first buckle 2081 is engaged with the second buckle 2091 through the second guiding inclined surface 2092.

[0082] Specifically, the longitudinal section of the second buckle 2091 is in an "L" shape, and when the handle 202 is horizontally placed, the transverse section of the first buckle 2081 is in an "L" shape; thus, when the handle 202 is vertically placed, the first buckle 2081 and the second buckle 2091 are hooked and cooperated with each other.

[0083] More specifically, a third limiting portion 2093 is further provided on the second buckle 2091. The third limiting portion 2093 is arranged at the end of the second buckle 2091 close to the sixth locking member 207. The third limiting portion 2093 can prevent the handle 202 from continuing to rotate in the direction away from the sixth locking member 207 after the seventh locking member 208 and the eighth locking member 209 are engaged, thereby restricting the rotation angle of the handle 202.

[0084] Of course, in other embodiments, the eighth locking member 209 includes a first buckle 2081, the sixth locking member 207 includes a second buckle 2091, and a second guiding inclined surface 2092 is provided on the second buckle 2091; when the seventh locking member 208 and the eighth locking member 209 are engaged, the first buckle 2081 is clamped with the second buckle 2091 through the second guiding inclined surface 2092.

[0085] That is to say, the specific setting positions of the first buckle 2081 and the second buckle 2091 are such that the handle 202 and the filter element body 201 can be locked at the second locking position through the clamping of the first buckle 2081 and the second buckle 2091; the first buckle 2081 can be arranged on the handle 202, and the first buckle 2081 can also be arranged on the filter element body 201; the second buckle 2091 can be arranged on the handle 202, and the second buckle 2091 can also be arranged on the filter element body 201.

[0086] In the embodiment of the present utility model, when the handle 202 rotates relative to the filter element body 201 to the first locking position, the handle 202 and the filter element body 201 are locked through the cooperation of the fifth locking member 206 and the sixth locking member 207; when the handle 202 rotates relative to the filter element body 201 to the second locking position, the handle 202 and the filter element body 201 are locked through the cooperation of the seventh locking member 208 and the eighth locking member 209.

[0087] In the embodiment of the present utility model, the handle 202 rotates between the first locking position and the second locking position, and the rotation range of the handle 202 is 0-90°; when the handle 202 is horizontally placed, the handle 202 is in the first locking position; when the handle 202 is vertically placed, the handle 202 is in the second locking position.

[0088] In the embodiment of the present utility model, a fifth locking member 206 is provided in the middle of the handle 202, and a seventh locking member 208 is provided at at least one end of the handle 202.

[0089] Preferably, a fifth locking member 206 is provided in the middle of the handle 202, and seventh locking members 208 are provided at both ends of the handle 202, so that both ends of the handle 202 can be clamped to the filter element body 201, making the force on the handle 202 uniform, avoiding deformation of the handle 202 due to uneven force after long-term use, and extending the service life of the handle 202.

[0090] It should be noted that the filter element body 201 is cylindrical, and for the convenience of use, the handle 202 is in a "U" shape.

[0091] Specifically, in order for the handle 202 to rotate relative to the filter element body 201 between the first locking position and the second locking position, the inner diameter of the handle 202 is larger than the outer diameter of the filter element body 201.

[0092] It should be noted that the handle 202 can be a plastic handle or a metal handle, and it is in a flat strip shape. When unlocking the fifth locking member 206 and the sixth locking member 207, the handle 202 needs to be pulled, and at this time, the handle 202 needs to undergo slight deformation, so that the second protrusion 2071 disengages from the third card slot 2061 on the handle 202 through the first guiding inclined surface 2062.

[0093] In the embodiment of the present utility model, a pulling portion 210 is provided on the handle 202. When the handle 202 is locked to the filter element body 201 through the second locking structure, the pulling portion 210 protrudes from the top of the filter element body 201.

[0094] Specifically, the pulling portion 210 extends along the length direction of the handle 202, so that the pulling portion 210 does not affect the rotation of the handle 202 between the first locking position and the second locking position, and the pulling portion 210 does not affect the cooperation and unlocking of the fifth locking member 206 and the sixth locking member 207.

[0095] More specifically, a convex portion is provided on the inner side of the pulling portion 210, and the convex portion is the force application position for the user to operate.

[0096] Since when the handle 202 is placed horizontally, the handle 202 is flush with the filter element body 201, the user can pull the handle 202 through the pulling portion 210, and there is a force application point during the operation of the handle 202, which is beneficial for use.

[0097] Specifically, the second locking member 40 is fixedly connected to the machine housing 10 relatively. The second locking member 40 and the machine housing 10 can be integrally formed. The second locking member 40 and the machine housing 10 can also be separately formed and then connected into one body through welding process or adhesive process, etc. The third locking member 203, the sixth locking member 207 and the eighth locking member 209 are all fixedly connected to the filter element body 201 relatively. The third locking member 203, the sixth locking member 207 and the eighth locking member 209 can be integrally formed with the filter element body 201. The third locking member 203, the sixth locking member 207 and the eighth locking member 209 can also be separately formed with the filter element body 201 and then connected into one body through welding process or adhesive process, etc. The fourth locking member 204, the fifth locking member 206 and the seventh locking member 208 are all fixedly connected to the handle 202 relatively. The fourth locking member 204, the fifth locking member 206 and the seventh locking member 208 can be integrally formed with the handle 202. The fourth locking member 204, the fifth locking member 206 and the seventh locking member 208 can also be separately formed with the handle 202 and then connected into one body through welding process or adhesive process, etc.

[0098] Refer to Figures 1 - 12 , the specific use process of the present utility model is as follows:

[0099] When installing the filter element 20: Rotate the first locking member 30 clockwise relative to the machine housing 10 to an inclined state. At this time, the sliding member 302 extends out of the base 301. The filter element 20 is inserted obliquely downward to the installation position. After the third locking member 203 is connected to the first locking member 30, the filter element 20 follows the first locking member 30 to rotate counterclockwise relative to the machine housing 10 to the vertical direction. The sliding member 302 is squeezed by the machine housing 10, and the sliding member 302 retracts. The third locking member 203 and the first locking member 30 cooperate, and the lower end of the filter element 20 is locked with the machine housing 10. The handle 202 rotates counterclockwise relative to the filter element body 201 to the first locking position. The fourth locking member 204 cooperates with the second locking member 40, and the handle 202 is locked with the machine housing 10, that is, the lower end of the filter element 20 is locked with the machine housing 10. At the same time, the fifth locking member 206 cooperates with the sixth locking member 207, and the handle 202 is locked with the filter element body 201 at the first locking position. In this way, the installation of the filter element 20 is completed.

[0100] When replacing the filter element 20: Pull the handle 202, and the fifth locking member 206 is separated from the sixth locking member 207. The handle 202 rotates clockwise relative to the filter element body 201 to the second locking position. The seventh locking member 208 cooperates with the eighth locking member 209, and the handle 202 is locked with the filter element body 201 at the second locking position. During the above process, the second locking member 40 is unlocked. The filter element 20 and the first locking member 30 rotate clockwise relative to the machine housing 10 to an inclined state. At this time, the sliding member 302 extends out of the base 301. The first locking member 30 is unlocked, and the user can take out the filter element 20 in the inclined upward direction. In this way, the removal of the filter element 20 is completed.

[0101] The assembly method of the filter element 20 of the present utility model can lock the filter element 20 with only two steps, namely rotating the filter element 20 and rotating the handle 202, and the operation is simple.
