[0039] The filter element assembly 100 and the water purification device 1000 according to the embodiment of the utility model are described below with reference to the accompanying drawings. It should be noted that the water purification device 1000 can be a water purifier, and the filter element assembly 100 is arranged in the water purifier for filtering water. A water purifier is a device that can process a water source containing impurities and harmful substances to make it pure and drinkable. Its main function is to filter out harmful substances such as suspended matter, bacteria, viruses, heavy metals, etc. in the water, while retaining minerals and trace elements in the water that are beneficial to the human body. There are many types of water purifiers. According to their different filtering methods, they can be mainly divided into reverse osmosis water purifiers, ultrafiltration water purifiers, activated carbon water purifiers, ceramic filtration water purifiers, etc. In general, a water purifier is an important equipment that can effectively improve water quality and ensure the safety of people's drinking water.

[0040] like Figure 1 and Figure 2 As shown, the filter element assembly 100 provided according to the present invention includes: a filter element body 110 and a filter element mounting seat 120 .

[0041] Specifically, the filter element body 110 has a filtering function, and a water outlet pipe 116 is provided on the filter element body 110. Water entering the filter element body 110, waste water generated after filtration, and pure water can all flow out through the corresponding water outlet pipe 116. The water outlet pipe 116 is suitable for connecting and communicating with the waterway plate. The waterway plate can be provided with a raw water channel, a waste water channel, and a pure water channel, etc. The water outlet pipe 116 on the filter element body 110 can be one or more, and each water outlet pipe 116 is connected and communicated with the corresponding waterway on the waterway plate.

[0042] See also Figure 2 and Figure 3 As shown, the filter element mounting seat 120 has a mounting cavity 121 inside, and one side of the mounting cavity 121 has an opening 122, and the filter element body 110 is suitable for being installed in the mounting cavity 121 through the opening 122. In this way, it is convenient to install the filter element body 110 on the filter element mounting seat 120. A limiting rib 111 is provided on the outer peripheral wall of the filter element body 110, and a limiting groove 123 is provided on the inner wall of the mounting cavity 121, and the limiting rib 111 is suitable for sliding along the limiting groove 123. The cooperation between the limiting rib 111 and the limiting groove 123 is used to limit the rotation of the filter element body 110 in its circumferential direction.

[0043] See also Figure 3 and Figure 4 As shown, the limiting function of the limiting groove 123 can be used to limit the movement range of the limiting rib 111, thereby limiting the movement range of the filter element body 110. Figure 2As shown, in order to facilitate the fitting of the limiting rib 111 into the limiting groove 123, a bell mouth 124 is provided at one end of the limiting groove 123, and the bell mouth 124 is communicated with the opening 122. It should be noted that, on the one hand, the bell mouth 124 has a guiding function, so that the limiting rib 111 can be guided into the limiting groove 123; on the other hand, the bell mouth 124 has the advantages of a wide mouth for entry and a narrow mouth for exit, so that the limiting rib 111 is conveniently fitted into the limiting groove 123.

[0044] According to the filter element assembly 100 of the embodiment of the utility model, the movement range of the limiting rib 111 is limited by utilizing the limiting function of the limiting groove 123, thereby limiting the movement range of the filter element body 110; further, by providing a bell mouth 124 at one end of the limiting groove 123, not only can the guiding function of the bell mouth 124 be utilized to guide the limiting rib 111 to fit into the limiting groove 123, but the bell mouth 124 also has the advantages of a wide mouth for entry and a narrow mouth for exit, thereby facilitating the limiting rib 111 to fit into the limiting groove 123.

[0045] According to some embodiments of the utility model, there are multiple limiting ribs 111, and the multiple limiting ribs 111 are spaced apart along the circumferential direction of the filter element body 110. In this way, the stability of the cooperation between the filter element body 110 and the filter element mounting seat 120 can be improved, and the filter element body 110 can be effectively prevented from rotating relative to the filter element mounting seat 120. In addition, when one of the multiple limiting ribs 111 is damaged, the other limiting ribs 111 can also play a limiting role, thereby improving the stability and safety of the cooperation between the filter element body 110 and the filter element mounting seat 120. Correspondingly, when there are multiple limiting ribs 111, the filter element mounting seat 120 is provided with a plurality of limiting grooves 123, and the plurality of limiting grooves 123 are arranged one-to-one with the plurality of limiting ribs 111.

[0046] According to some embodiments of the present invention, see Figure 6 As shown, the width of the limiting rib 111 is 2 mm-5 mm. This can enhance the structural strength of the limiting rib 111, improve the matching stability between the limiting rib 111 and the limiting groove 123, and prevent the filter element body 110 from rotating relative to the filter element mounting seat 120. Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the limiting rib 111 is linear. It is understandable that the limiting rib 111 extends in a straight line, so that the limiting rib 111 can be smoothly matched into the limiting groove 123, thereby improving the matching convenience between the filter element body 110 and the filter element mounting seat 120. In addition, the linear limiting rib 111 is simple and intuitive in design, with relatively low processing cost, and is easy to process and install.

[0047] According to some embodiments of the present invention, see Figure 6As shown, the end of the limiting rib 111 has a guiding slope 112. The guiding slope 112 has a guiding function, which can guide the filter element body 110 into the limiting groove 123. For example, when installing the filter element body 110 on the filter element mounting seat 120, the filter element body 110 can be first inserted into the opening 122 of the mounting cavity 121, and then the guiding slope 112 on the limiting rib 111 is used to slide into the bell mouth 124. Under the guiding action of the guiding slope 112 and the bell mouth 124, the limiting rib 111 slides into the limiting groove 123, and the limiting rib 111 slides along the limiting groove 123, and moves the filter element body 110 to a predetermined position. Therefore, under the guiding action of the guiding slope 112 and the bell mouth 124, the filter element body 110 can be smoothly installed to a predetermined position. In addition, it should be noted that the inclined surface on the guiding bevel 112 not only facilitates demoulding, but also can effectively improve stress concentration, prevent fatigue damage of the limiting rib 111, and effectively extend the service life of the limiting rib 111.

[0048] Combination Figure 5 and Figure 6 As shown, according to some embodiments of the utility model, the filter element body 110 further includes: a body portion 113 and a cover 114. Specifically, the limiting rib 111 is provided on the outer peripheral wall of the body portion 113, the body portion 113 is provided in the mounting cavity 121, and the body portion 113 is slidable along the length direction of the limiting groove 123. The cover 114 is provided on the end of the body portion 113, a part of the structure of the cover 114 is located in the opening 122, and the cover 114 is rotatable relative to the body portion 113.

[0049] It can be understood that in the axial direction of the body part 113 or in the direction in which the body part 113 moves along the limiting groove 123, the body part 113 is slidable relative to the filter element mounting seat 120, and the body part 113 is stationary relative to the filter element mounting seat 120; in the circumferential direction of the body part 113 or in the circumferential direction in which the body part 113 moves along the limiting groove 123, the body part 113 is stationary relative to the filter element mounting seat 120, and the cover 114 is rotatable relative to the body part 113. On the one hand, it is convenient to assemble the filter element body 110 onto the filter element mounting seat 120; on the other hand, it is also convenient to install the water outlet pipe 116 of the filter element body 110 onto the waterway plate.

[0050] In order to facilitate the operator to hold the filter element body 110, see Figure 5 and Figure 6 As shown, a handle portion 117 is provided on the side of the cover body 114 facing away from the main body 113 . The handle portion 117 is in a knob shape, so that an operator can rotate the cover body 114 by holding the handle portion 117 .

[0051] See also Figure 6As shown, according to some embodiments of the present invention, in the length direction of the limiting rib 111, the width of the cover 114 is smaller than the length of the limiting rib 111. Figure 6 As shown, the width of the cover 114 is L1, and the length of the limiting rib 111 is L2, where L2>L1. By setting the length of the limiting rib 111 to be greater than the width of the cover 114, when installing the filter element body 110 on the filter element mounting seat 120, the filter element body 110 can be first inserted into the opening 122 of the mounting cavity 121. Under the condition of being blocked by the cover 114 structure, the assembler can observe the position of the limiting rib 111, thereby facilitating the adjustment of the limiting rib 111 to the position of the bell mouth 124.

[0052] In addition, when the filter element body 110 is inserted into the opening 122 and becomes misaligned, since the length of the limiting rib 111 is greater than the width of the cover body 114 , the assembler can promptly discover that the position of the limiting rib 111 does not correspond to the position of the bell mouth 124 , thereby facilitating the assembler to promptly adjust the position of the limiting rib 111 and further facilitating the assembly of the filter element body 110 into the filter element mounting seat 120 .

[0053] Combination Figure 5 and Figure 6 As shown, according to some embodiments of the utility model, a rotating ridge 115 is provided on the cover body 114, and a rotating groove 125 is provided on the inner circumferential wall of the mounting cavity 121, the rotating groove 125 extends along the circumferential direction of the main body 113, and the limiting groove 123 extends along the length direction of the main body 113. With the cooperation between the rotating ridge 115 and the rotating groove 125, and the cooperation between the limiting groove 123 and the limiting rib 111, the cover body 114 rotates relative to the main body 113, and the cover body 114 and the main body 113 move along the direction of the limiting groove 123.

[0054] It can be understood that, with the cooperation of the rotating groove 125 and the rotating ridge 115, the cover body 114 plays a role in pushing the main body 113 to move, so that the main body 113 can move along the extension direction of the limiting groove 123, so that the filter element body 110 can move in the installation cavity 121 along the extension direction of the limiting groove 123, and then the filter element body 110 can have an assembly force in its axial direction, so that when the filter element body 110 is inserted into the installation cavity 121, the filter element body 110 also has the assembly force to be plugged into the waterway plate, so as to achieve the purpose of plugging the filter element body 110 with the waterway plate. For the sake of convenience, the cooperation of the rotating groove 125 and the rotating ridge 115 can be understood as a threaded cooperation. In order to facilitate the cooperation of the rotating groove 125 and the rotating ridge 115, see Figure 2 As shown, the opening 122 of the rotation groove 125 is communicated with the bell mouth 124 .

[0055] Combine the following Figure 1-Figure 6The filter element assembly 100 according to the embodiment of the present invention is described in detail. It is worth noting that the following description is only an exemplary description, rather than a specific limitation of the present invention.

[0056] See also Figure 1 As shown, the filter element assembly 100 includes a filter element body 110 and a filter element mounting seat 120. The filter element body 110 has a filtering function, and a water outlet pipe 116 is provided on the filter element body 110. Water entering the filter element body 110, waste water generated after filtration, and pure water can all flow out through the corresponding water outlet pipe 116. The water outlet pipe 116 is plugged into the waterway plate, and the corresponding water outlet pipe 116 is suitable for communicating with the corresponding waterway on the waterway plate.

[0057] See also Figure 2 and Figure 3 As shown, the filter element mounting seat 120 has an installation cavity 121 inside, and one side of the installation cavity 121 has an opening 122, and the filter element body 110 is suitable for being installed in the installation cavity 121 through the opening 122. A limiting rib 111 is provided on the outer peripheral wall of the filter element body 110, and a limiting groove 123 is provided on the inner wall of the installation cavity 121, and the limiting rib 111 is suitable for sliding along the limiting groove 123. The cooperation between the limiting rib 111 and the limiting groove 123 is used to limit the rotation of the filter element body 110 in its circumferential direction.

[0058] Combination Figure 5 and Figure 6 As shown, the filter element body 110 also includes a body part 113 and a cover body 114. Among them, the limiting rib 111 is arranged on the outer peripheral wall of the body part 113, the body part 113 is arranged in the installation cavity 121, and the body part 113 can slide along the length direction of the limiting groove 123. The cover body 114 is covered at the end of the body part 113, and part of the structure of the cover body 114 is located in the opening 122, and the cover body 114 can rotate relative to the body part 113. It can be understood that in the axial direction of the body part 113 or the direction in which the body part 113 moves along the limiting groove 123, the body part 113 can slide relative to the filter element mounting seat 120, and the body part 113 is stationary relative to the filter element mounting seat 120; in the circumferential direction of the body part 113 or the circumferential direction in which the body part 113 moves along the limiting groove 123, the body part 113 is stationary relative to the filter element mounting seat 120, and the cover body 114 can rotate relative to the body part 113. On the one hand, it is convenient to assemble the filter element body 110 onto the filter element mounting seat 120; on the other hand, it is also convenient to install the water outlet pipe 116 of the filter element body 110 onto the waterway plate.

[0059] See also Figure 6As shown, a rotating ridge 115 is provided on the cover body 114, and a rotating groove 125 is provided on the inner circumferential wall of the mounting cavity 121. The rotating groove 125 extends along the circumferential direction of the main body 113, and the limiting groove 123 extends along the length direction of the main body 113. With the cooperation between the rotating ridge 115 and the rotating groove 125, and the cooperation between the limiting groove 123 and the limiting rib 111, the cover body 114 rotates relative to the main body 113, and the cover body 114 and the main body 113 move along the direction of the limiting groove 123. It can be understood that, with the cooperation of the rotating groove 125 and the rotating ridge 115, the cover body 114 plays a role in pushing the main body 113 to move, so that the main body 113 can move along the extension direction of the limiting groove 123, so that the filter element body 110 can move in the installation cavity 121 along the extension direction of the limiting groove 123, and then the filter element body 110 can have an assembly force in its axial direction, so that when the filter element body 110 is inserted into the installation cavity 121, the filter element body 110 also has an assembly force to be plugged into the waterway plate, thereby achieving the purpose of plugging the filter element body 110 with the waterway plate.

[0060] See also Figure 6 As shown, the width of the limiting rib 111 is 2mm-5mm, and the end of the limiting rib 111 has a guiding slope 112. The guiding slope 112 has a guiding function, which can guide the filter element body 110 into the limiting groove 123. For example, when installing the filter element body 110 on the filter element mounting seat 120, the filter element body 110 can be first inserted into the opening 122 of the mounting cavity 121, and then the guiding slope 112 on the limiting rib 111 is used to slide into the bell mouth 124. Under the guiding effect of the guiding slope 112 and the bell mouth 124, the limiting rib 111 slides into the limiting groove 123, and the limiting rib 111 slides along the limiting groove 123, and the filter element body 110 is moved to a predetermined position.

[0061] In the length direction of the limiting rib 111, the width of the cover 114 is smaller than the length of the limiting rib 111. Figure 6 As shown, the width of the cover 114 is L1, and the length of the limiting rib 111 is L2, where L2>L1. By setting the length of the limiting rib 111 to be greater than the width of the cover 114, when installing the filter element body 110 on the filter element mounting seat 120, the filter element body 110 can be first inserted into the opening 122 of the mounting cavity 121. Even if the cover 114 structure blocks it, the assembler can still observe the position of the limiting rib 111, so that it is convenient to adjust the limiting rib 111 to the position of the bell mouth 124.

[0062] See also Figure 1 and Figure 3As shown, the water purification device 1000 according to the embodiment of the utility model comprises a housing 200 and the filter element assembly 100 as described above. Specifically, the filter element assembly 100 is arranged in the housing 200, the housing 200 and the filter element mounting seat 120 of the filter element assembly 100 are an integrally formed part, and the opening 122 of the filter element assembly 100 is arranged on the housing 200. It should be noted that the filter element mounting seat 120 and the housing 200 are formed at the same time through a single injection molding process to construct an integrated part, which can reduce production costs, simplify assembly steps, reduce production costs, and improve production efficiency.

[0063] According to the water purification device 1000 of the embodiment of the utility model, the moving range of the limiting rib 111 is limited by utilizing the limiting function of the limiting groove 123, thereby limiting the movement range of the filter element body 110; further, by providing a bell mouth 124 at one end of the limiting groove 123, not only can the guiding function of the bell mouth 124 be utilized to guide the limiting rib 111 to fit into the limiting groove 123, but the bell mouth 124 also has the advantages of a wide mouth for entry and a narrow mouth for exit, thereby facilitating the limiting rib 111 to fit into the limiting groove 123.
