When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0027] In the process of assembling the filter element of the related art, the filter element is usually used to drive the water channel seal on the shell of the water purification equipment to rotate, thereby realizing the assembly and sealing of the filter element. However, this assembly method requires the user to rotate the entire filter element, which has the problem of large torque and difficulty in installation, affecting the user's experience.

[0028] Based on this, the inventor improved the assembly structure of the filter element, provided a mounting cover that is rotatably connected to the main body of the filter element, and provided a fastener at the mounting cover, so that the filter element can be assembled and fixed by rotating the mounting cover alone, thereby reducing the torque that the user needs to apply to the filter element, reducing the difficulty of installation and disassembly of the filter element, and improving the user experience.

[0029] The utility model provides a filter element 100, which is applied to a water purification device. The filter element 100 includes a main body 10 and a mounting cover 20. The mounting cover 20 is arranged at one end of the main body 10 and is rotatably connected to the main body 10. The mounting cover 20 is provided with a fastener 21, and the fastener 21 is used to connect and fasten with the water purification device when the mounting cover 20 and the main body 10 rotate.

[0030] The filter element 100 is a consumable material used in water purification equipment. Its function is to introduce water from its inlet, remove impurities and harmful substances in the water source after filtering through the internal multi-layer filter element, and discharge the filtered water from the outlet for user use.

[0031] The filter element 100 includes a main body 10 and a mounting cover 20 , wherein the main body 10 is a main functional component of the filter element 100 , and is a component in the water purification device for direct connection to an external water source.

[0032] The mounting cover 20 is a component in the filter element 100 for connecting with the water purification device. During use, the user can install or remove the filter element 100 by connecting or removing the mounting cover 20 from the water purification device.

[0033] The mounting cover 20 is disposed at one end of the main body 10. A possible implementation is that the mounting cover 20 is disposed at an end of the main body 10 where no water inlet or water outlet is disposed, so that during the installation of the filter element 100, the water inlet and the water outlet can be installed to the water purification equipment by plugging, which is beneficial to the alignment and sealing of the water inlet and the water outlet.

[0034] For example, in some embodiments, the water inlet and the water outlet of the main body 10 can be centrally arranged at one end, and the installation cover 20 can be arranged at one end of the main body 10 away from the water inlet and the water outlet. This can improve the installation success rate of the water inlet and the water outlet of the filter element 100, reduce the influence of the installation cover 20 on the position of the water inlet and the water outlet when connected to the water purification equipment, and improve the reliability of the filter element.

[0035] The mounting cover 20 is rotatably connected to the main body 10, which means that the mounting cover 20 can rotate relative to the main body 10. In this way, during the installation of the filter element 100, the user can connect the main body 10 to the water purification device, and then rotate the mounting cover 20 alone to achieve a secure connection between the filter element 100 and the water purification device. This reduces the difficulty of users installing or removing the filter element 100 and improves the user experience.

[0036] The connection between the mounting cover 20 and the water purification device can be achieved by providing a fastener 21 on the mounting cover 20 , wherein the fastener 21 is used to connect and fasten with the water purification device when the mounting cover 20 and the main body 10 rotate.

[0037] Specifically, in these embodiments of the present invention, when the user rotates the mounting cover 20 to rotate the mounting cover 20 relative to the main body 10, the mounting cover 20 also rotates relative to the water purification device, thereby enabling the fastener 21 provided on the mounting cover 20 to be connected and fastened to the water purification device.

[0038] In these embodiments of the present invention, the fastener 21 is used to form a detachable structure with the water purification device that can be installed and disassembled by rotation.

[0039] Exemplarily, in some embodiments, the fastener 21 and the water purification device can be connected by magnetic attraction, that is, there is a magnet between the fastener 21 and at least one of the water purification device. When the user rotates the installation cover 20, the fastener 21 follows and rotates to the installation position of the water purification device, and the fastener 21 and the water purification device are connected by magnetic attraction.

[0040] In some embodiments, a threaded fastening structure may be provided between the fastener 21 and the water purification device, that is, the fastener 21 is an internal thread (or external thread) provided on the mounting cover 20, and an external thread (or internal thread) matching the internal thread (or external thread) is provided in the water purification device. In this way, when the user controls the mounting cover 20 to rotate, the fastener 21 is threadedly connected to the water purification device to realize the connection or disassembly of the filter element 100 and the water purification device.

[0041] It should be noted that the connection between the fastener 21 and the water purification device refers to the connection between the fastener 21 and a partial structure in the water purification device. By way of example, in some embodiments, the fastener 21 may be provided for connection with the middle shell of the water purification device to achieve assembly and disassembly of the filter element 100.

[0042] In some embodiments, the mounting cover 20 includes an end plate 22 and a side plate 23 . The side plate 23 is disposed around the periphery of the end plate 22 , and the fastener 21 is disposed on the outer wall surface of the side plate 23 .

[0043] The mounting cover 20 includes an end plate 22 and a side plate 23, which means that the mounting cover 20 is a semi-enclosed structure, that is, the end plate 22 and the side plate 23 together form a semi-enclosed structure with an open end. In this way, the opening end of the mounting cover 20 can be aligned with the main body 10 and then connected to the main body 10, so that the end plate 22 is opposite to the end wall of the main body 10; the side plate 23 is arranged around the periphery of the end plate 22, so that the side plate 23 can be covered on the periphery of the side wall of the main body 10, thereby improving the structural strength between the mounting cover 20 and the main body 10.

[0044] The fastener 21 is arranged on the outer wall surface of the side plate 23, which means that when the mounting cover 20 is connected to the main body 10, the fastener 21 is arranged on the surface of the side plate 23 away from the main body 10, so as to be connected with the external water purification equipment when the mounting cover 20 rotates relative to the main body 10. Such a setting method is conducive to the structural design of the water purification equipment, so that the water purification equipment can reduce the longitudinal space, which is conducive to the miniaturization of the product.

[0045] In some embodiments, the fastener 21 can be disposed on the surface of the end plate 22 facing away from the main body 10 according to different structures of the filter element 100 . The above implementation manner can be selected according to different models of the filter element 100 .

[0046] In these embodiments of the utility model, the cross-sectional shape of the end plate 22 can be circular, in which case the side plate 23 can cooperate with the end plate 22 to form a hollow cylinder or truncated cone shape with one end open; in some embodiments, the cross-sectional shape of the end plate 22 can be rectangular, in which case the side plate 23 can cooperate with the end plate 22 to form a hollow quadrangular prism with one end open.

[0047] In some embodiments, at least a portion of the side plate 23 is an arc segment, and the fastener 21 is disposed on the arc segment; the center of the arc segment falls on the rotation axis of the mounting cover 20 .

[0048] The center of the arc segment falls on the rotation axis of the mounting cover 20 , wherein the rotation axis of the mounting cover 20 is a virtual axis, which is the rotation axis when the mounting cover 20 and the main body 10 rotate relative to each other.

[0049] In these embodiments of the present invention, at least part of the side plate 23 is an arc segment, which means that at least part of the side plate 23 is an arc segment with the center falling on the rotation axis on a plane perpendicular to the rotation axis of the mounting cover 20. In this way, by arranging the fastener 21 on the arc segment, when the mounting cover 20 rotates relative to the main body 10, the fastener 21 can also be connected to the water purification device by rotating, which has a simple structure and is conducive to the miniaturization design of the water purification device.

[0050] Illustratively, in these embodiments of the present invention, the cross-sectional shape of the side panel 23 perpendicular to the rotation axis of the mounting cover 20 can be set to be circular. Based on this, when the fastener 21 is connected to the water purification equipment by rotation, the periphery can better fit with the water purification equipment, thereby reducing the space occupied by the filter element 100 in the water purification equipment and further improving the miniaturization performance of the water purification equipment.

[0051] In some embodiments, the mounting cover 20 further includes a knob 24 , which is disposed on a side of the end plate 22 facing away from the main body 10 .

[0052] The function of the knob 24 is to facilitate the user to rotate the mounting cover 20 . Therefore, the knob 24 is disposed on the side of the end plate 22 away from the main body 10 , which is convenient for the user to operate.

[0053] In the cross section perpendicular to the rotation axis of the mounting cover 20 , the shape of the knob 24 may be, but is not limited to, rectangular, circular, or triangular, and may be selected according to the actual application scenario of the filter element 100 .

[0054] In these embodiments of the present invention, the knob 24 can be set to a hollow structure, that is, the knob 24 can cooperate with the aforementioned end plate 22 to form a closed cavity. In this way, on the one hand, the weight of the knob 24 can be reduced and production materials can be saved. On the other hand, the aforementioned cavity can also be used to accommodate the connection structure between the installation cover 20 and the main body 10, thereby improving the integrity of the filter element 100.

[0055] In some embodiments, the main body 10 includes an end wall 11 close to the mounting cover 20 , and the end wall 11 is connected to the mounting cover 20 via a connecting member 30 ; the connecting member 30 is disposed on the rotation axis of the mounting cover 20 .

[0056] The main body 10 includes an end wall 11 close to the mounting cover 20 , which means that the outer shell of the main body 10 includes the end wall 11 , wherein the outer shell may further include a shell body 12 with an open end, and the end wall 11 and the shell body 12 together form an outer shell having an accommodating space.

[0057] It can be known that the main body 10 should also include a filtering structure 13 arranged in the accommodating space. Through the structural design of the shell 12 and the end wall 11, the external water flow is divided into filtered waste water and filtered clean water after passing through the filtering structure 13, and the two can be discharged through different drain ports arranged in the shell 12.

[0058] The end wall 11 is the portion of the housing close to the mounting cover 20. In some embodiments, the end wall 11 may be a semi-enclosed structure with one end open, in which case the end wall 11 is relatively connected to the opening of the housing 12 to form the aforementioned accommodation space.

[0059] The end wall 11 and the mounting cover 20 are connected via a connecting piece 30 , and the connecting piece 30 is disposed on the rotation axis of the mounting cover 20 . The purpose of such a configuration is to enable the mounting cover 20 to be connected to the end wall 11 while being able to rotate relative to the end wall 11 .

[0060] In these embodiments of the utility model, the connecting member 30 can be set as a screw or a bolt. During the assembly process of the mounting cover 20 and the end wall 11, it is necessary to control the tightness of the connecting member 30 to reduce the probability of limiting the rotation function of the mounting cover 20 and the main body 10 due to the connecting member 30 being set too tight.

[0061] Exemplarily, in an embodiment where the connecting member 30 is a screw, the connecting member 30 can be arranged to pass through the end plate 22 and the end wall 11 along the rotation axis direction of the mounting cover 20. At the same time, a gap of 0.4 mm to 1.2 mm can be arranged between the head of the connecting member 30 (screw) and the end plate 22, so that the end plate 22 and the end wall 11 can be effectively connected through the connecting member 30, and there is a certain degree of rotational freedom between the end plate 22 and the end wall 11, so that the user can rotate the mounting cover 20 by rotating the end plate 22.

[0062] In some embodiments of the present invention, the gap between the head of the connecting member 30 (screw) and the end plate 22 may be set to 0.6 mm, 0.8 mm or 1.0 mm.

[0063] In some embodiments, the end wall 11 is provided with an arc groove 111 , the center of which falls on the rotation axis of the mounting cover 20 ; the mounting cover 20 is provided with a limiting boss 25 , which is clamped in the arc groove 111 .

[0064] The arc groove 111 serves to provide a guide for the rotation of the installation cover 20 , thereby improving the rotation accuracy of the installation cover 20 .

[0065] The center of the circular arc groove 111 falls on the rotation axis of the installation cover 20 , so that when the installation cover 20 rotates relative to the main body 10 , the installation cover 20 can be guided to rotate along the rotation axis.

[0066] In some embodiments, the arc groove 111 can be set on the side of the periphery of the end wall 11. In this case, the limiting boss 25 of the mounting cover 20 can be set on the inner side of the side plate 23 and clamped in the limiting boss 25; in some embodiments, the arc groove 111 can also be set on the surface of the end wall 11 away from the aforementioned accommodating space. In this case, the limiting boss 25 of the mounting cover 20 can be set on the surface of the end plate 22 close to the end wall 11 and clamped in the limiting boss 25.

[0067] In some embodiments, a first positioning rib 1111 is provided in the arc groove 111, and the first positioning rib 1111 is provided at one end of the arc groove 111, and the limiting boss 25 is provided with a first avoidance groove 251; when the mounting cover 20 and the water purification equipment are in a connected and fastened state, the first positioning rib 1111 is clamped in the first avoidance groove 251, and the first positioning rib 1111 and the first avoidance groove 251 are arranged in a direction parallel to the rotation axis of the mounting cover 20.

[0068] The first positioning rib 1111, as the name implies, has one of the functions of providing positioning for the rotation of the mounting cover 20, that is, when the mounting cover 20 is rotated so that the fastener 21 can be connected to the water purification equipment, the first positioning rib 1111 can provide positioning and prompting effects for the limiting boss 25.

[0069] Based on this, the first positioning rib 1111 is arranged at one end of the arc groove 111, which means that the first positioning rib 1111 is arranged at one end where the mounting cover 20 can be stably connected to the water purification equipment after rotation.

[0070] The limiting boss 25 is provided with a first avoidance groove 251, which means that a groove structure whose shape matches the first positioning rib 1111 is formed by a depression on the outer surface of the limiting boss 25, so that when the limiting boss 25 rotates to the position of the first positioning rib 1111 along with the mounting cover 20, the first positioning rib 1111 can be inserted into the first avoidance groove 251, thereby realizing the function of positioning the mounting cover 20 by using the first positioning rib 1111.

[0071] It should be noted that in order to improve the smoothness of the limiting boss 25 when it is rotated and inserted into the first positioning rib 1111, the connection between the first positioning rib 1111 and the first avoidance groove 251 in the rotation direction can be set to be rounded, thereby improving the smoothness of the first positioning rib 1111 inserted into the first avoidance groove 251.

[0072] In addition, in these embodiments of the present invention, it is also arranged that when the mounting cover 20 and the water purification equipment are in a connected and fastened state, the first positioning rib 1111 and the first avoidance groove 251 are arranged in a direction parallel to the rotation axis of the mounting cover 20. In this way, the pressure generated by the filter element 100 during operation can be utilized to press the first avoidance groove 251 and the first positioning rib 1111 tightly, thereby reducing the probability of displacement of the filter element 100 due to pressure changes or vibrations during operation, having a good anti-retraction effect of the filter element 100, and further improving the stability of the filter element 100 during operation.

[0073] Specifically, during the continuous operation of the water purification equipment, vibrations will be continuously generated, and such vibrations will inevitably affect the connection performance between the installation cover 20 and the main body 10, and during the operation of the filter element 100, there will be a phenomenon of pressure increase inside the filter element 100. In this way, through the pressure increase inside the filter element 100, a force toward the end plate 22 will be generated on the end wall 11. At this time, since the first positioning rib 1111 and the first avoidance groove 251 are arranged in a direction parallel to the rotation axis of the installation cover 20, this pressure can be used to press the first positioning rib 1111 and the first avoidance groove 251, further improving the structural stability of the filter element 100 during operation, so as to cope with the vibrations generated during operation, reduce the probability of displacement of the filter element 100 due to pressure changes or vibrations during operation, and have a good filter element 100 anti-retraction effect, so that the stability and reliability of the filter element 100 are better.

[0074] In some embodiments, a second positioning rib 1112 is provided in the circular arc groove 111, and the second positioning rib 1112 is connected to the first positioning rib 1111, and one of the first positioning rib 1111 and the second positioning rib 1112 is provided on the bottom surface of the circular arc groove 111, and the other is provided on the wall surface of the circular arc groove 111; the limiting boss 25 is provided with a second avoidance groove 252, and when the mounting cover 20 and the water purification equipment are in a connected and tightened state, the second positioning rib 1112 is clamped in the second avoidance groove 252.

[0075] The structure of the second positioning rib 1112 is the same as that of the first positioning rib 1111, and both are protrusions formed by the inner wall of the arc groove 111 protruding inward. The function of the second positioning rib 1112 is to enhance the positioning performance of the installation cover 20 after it is rotated into place. At the same time, the second positioning rib 1112 can also be used to remind the user that the installation is in place.

[0076] In these embodiments of the present invention, the second positioning rib 1112 is connected to the first positioning rib 1111 to provide a positioning effect for the limiting boss 25 from different directions.

[0077] One of the first positioning rib 1111 and the second positioning rib 1112 is arranged on the bottom surface of the arc groove 111, and the other is arranged on the wall surface of the arc groove 111, which means that in different embodiments of the setting position of the arc groove 111, there are differences in the setting positions of the first positioning rib 1111 and the second positioning rib 1112.

[0078] For example, in the embodiment where the arc groove 111 is arranged on the side of the periphery of the end wall 11, the first positioning rib 1111 can be arranged on the groove wall surface of the arc groove 111, and the second positioning rib 1112 can be arranged on the groove bottom surface of the arc groove 111; and in the embodiment where the arc groove 111 is arranged on the surface of the end wall 11 away from the aforementioned accommodation space, the first positioning rib 1111 can be arranged on the groove bottom surface of the arc groove 111, and the second positioning rib 1112 can be arranged on the groove wall surface of the arc groove 111. Such an arrangement ensures that no matter which embodiment the arc groove 111 is arranged in, the first positioning rib 1111 and the first avoidance groove 251 are always arranged in a direction parallel to the rotation axis of the installation cover 20, and then they are pressed and tightened during the operation of the filter element 100, thereby improving the structural consistency of the installation cover 20 and the main body 10 when the filter element 100 is in operation.

[0079] The structure and function of the second avoidance groove 252 are similar to those of the first avoidance groove 251 , and are not described in detail herein.

[0080] In some embodiments, the fastener 21 is used to form a slot-type buckle or a compression-type buckle with the water purification device.

[0081] In some embodiments of the present invention, the fastener 21 and the water purification device form a slot-type buckle position, that is, the fastener 21 is a protruding portion arranged on the periphery of the side panel 23. At the same time, a corresponding slot needs to be arranged at the middle shell position of the water purification device. In this way, during the rotation of the mounting cover 20, the fastener 21 can be inserted into the slot at the middle shell position, thereby realizing a detachable connection between the mounting cover 20 and the water purification device.

[0082] In some embodiments, the fastener 21 and the water purification equipment form a compression-type buckle position, which means that the fastener 21 can be an elastic plate structure, and a snap-on structure with an inclined surface is provided at the middle shell position of the water purification equipment. At this time, the fastener 21 can be moved to the inclined surface part through the rotation of the mounting cover 20, and then the spring of the fastener 21 is compressed and passed by using the inclined surface, and then the spring bounces up to realize the detachable connection between the mounting cover 20 and the water purification equipment.

[0083] The embodiment of the utility model further provides a water purification device, which includes a filter element 100 provided in any of the aforementioned embodiments.

[0084] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
