[0035] The present utility model will be further described in detail below with reference to the drawings.
[0036] As Figure 1 、 Figure 2 shown, a filtering device provided by the present application includes a filter element 200 and a base 100. The filter element 200 and the base 100 are detachably connected to facilitate the replacement of the filter element 200.
[0037] As Figure 4 、 Figure 5As shown in the figure, the above-mentioned base 100 includes a main body 13 and a water-blocking member 11. The main body 13 is provided with an assembly port 131 for assembling the filter element 200 and a first flow channel 132 for water circulation, and the first flow channel 132 communicates with the assembly port 131; the water-blocking member 11 is arranged inside the assembly port 131, and the water-blocking member 11 is provided with a second flow channel 111 for the flow of water, and the second flow channel 111 is used to communicate with the water flow channel 1123 inside the filter element 200. After the filter element 200 is assembled with the base 100, the water-blocking member 11 is arranged between the filter element 200 and the main body 13 to control the connection or disconnection between the first flow channel 132 and the second flow channel 111. When the first flow channel 132 is connected to the second flow channel 111, the water-blocking member 11 is in the first state, and when the first flow channel 132 is disconnected from the second flow channel 111, the water-blocking member 11 is in the second state. Through the above design, when the filter element 200 is detached from the base 100, the water-blocking member 11 can disconnect the first flow channel 132 from the second flow channel 111, so that the water remaining inside the base 100 is sealed inside the first channel 1123 inside the base 100, thereby preventing the water inside the base 100 from leaking out.
[0038] The technical details of each component will be introduced one by one below.
[0039] In some embodiments, such as Figure 3 、 Figure 5As shown in the figure, the above-mentioned water-blocking member 11 is rotationally attached to the main body 13. The water-blocking member 11 is arranged on the bottom surface of the assembly port 131 of the main body 13 in a rotationally attached manner. The water-blocking member 11 can be rotated from the first state to the second state or from the second state to the first state. When the water-blocking member 11 rotates to the first state, the first flow channel 132 is communicated with the second flow channel 111. The water inside the base 100 can flow into the second flow channel 111 through the first flow channel 132 and then flow into the inside of the filter element 200. When the water-blocking member 11 rotates to the second state, the first flow channel 132 is disconnected from the second flow channel 111, and the water inside the first flow channel 132 cannot flow into the second flow channel 111 and is sealed inside the first flow channel 132 to avoid leakage. Moreover, the filter element 200 is rotationally engaged with the base 100. When the filter element 200 rotates, it can drive the water-blocking member 11 to rotate together, so that the water-blocking member 11 can be switched between the first state and the second state along with the rotation of the filter element 200. When assembling the filter element 200, the filter element 200 is rotationally clamped with the base 100, and the water-blocking member 11 is driven by the filter element 200 to rotate from the second state to the first state. At this time, the first flow channel 132 is communicated with the second flow channel 111, and the water inside the base 100 can flow into the filter element 200 through the water-blocking member 11; when disassembling the filter element 200, the filter element 200 is rotationally separated from the base 100, and the water-blocking member 11 is driven by the filter element 200 to rotate to the second state. At this time, the first flow channel 132 is disconnected from the second flow channel 111, and the water inside the base 100 cannot flow into the filter element 200 and is sealed inside the first flow channel 132, thereby preventing water leakage.
[0040] The above design can also enable the filter element 200 and the base 100 to rotate synchronously, without the need for additional operations on the water-blocking member 11 alone, which can prevent water leakage without adding extra steps to the assembly of the filter element 200.
[0041] In some embodiments, as Figure 5 shown, the above-mentioned first flow channel 132 includes a first water inlet 1321 and a second water inlet 1111, and the above-mentioned second flow channel 111 includes a second water inlet 1111 and a second water outlet 1112. When the water-blocking member 11 rotates to the first state, the first water inlet 1321 is communicated with the second water inlet 1111, and the first water outlet 1322 is communicated with the second water outlet 1112; when the water-blocking member 11 rotates to the second state, the first water inlet 1321 is disconnected from the second water inlet 1111, and the first water outlet 1322 is disconnected from the second water outlet 1112.
[0042] In practical applications, when the filter element 200 is rotationally engaged with the base 100, the water-blocking member 11 is in the first state. Water flows into the second water inlet 1111 through the first water inlet 1321, then flows into the interior of the filter element 200 for filtration. The filtered water flows out of the interior of the filter element 200 into the second water outlet 1112, and then flows out through the first water outlet 1322. Please refer again to Figure 5 , after the water-blocking member 11 rotates to the second state, the first water inlet 1321 is offset from the second water outlet 1112, and the first water outlet 1322 is offset from the second water outlet 1112. As a result, the water remaining in the first water inlet 1321 and the first water outlet 1322 is sealed inside the first water inlet 1321 and the first water outlet 1322, thereby avoiding water leakage.
[0043] In some embodiments, such as Figure 5 , Figure 6 shown, both the first water inlet 1321 and the first water outlet 1322 of the above-mentioned water-blocking member 11 are provided with a pipe body 112. The pipe body 112 is arranged on the side of the water-blocking member 11 close to the filter element 200. A channel 1123 for water flow is opened inside the pipe body 112, and the channel 1123 is in a communicating state with the first water inlet 1321 or the first water outlet 1322.
[0044] In practical applications, the above-mentioned pipe body 112 is used to be inserted into the interior of the filter element 200 so that the first water inlet 1321 and the first water outlet 1322 are correspondingly communicated with the pipelines inside the filter element 200. The pipe body 112 can directly send water into the interior of the filter element 200; please refer to Figure 6 , at one end of the pipe body 112 close to the filter element 200, there are provided a holding portion 1121 and a flowing portion 1122. The holding portion 1121 and the flowing portion 1122 are alternately arranged at intervals around the central axis of the free end of the pipe body 112; among them, in the direction from the end of the pipe body 112 close to the filter element 200 to the other end of the pipe body 112, the height of the flowing portion 1122 is greater than the height of the holding portion 1121. When the pipe body 112 is inserted into the interior of the filter element 200, the holding portion 1121 abuts against the side wall of the pipeline inside the filter element 200, and water can flow into or out of the filter element 200 through the flowing portion 1122. Such a design can ensure that the water flow between the pipe body 112 and the filter element 200 will not decrease due to the right-angle connection structure between the pipe body 112 and the filter element 200, and water can flow into or out of the pipe body 112 through the flowing portion 1122, ensuring the flow rate of the filtering device in actual use.
[0045] In some embodiments, such as Figure 3 , Figure 5As shown, a cylinder 113 is further provided on one side of the water blocking member 11 close to the filter element 200. The main body 13 and the pipe body 112 are arranged on the same side of the water blocking member 11, and the main body 13 is used to be inserted into the assembly end of the filter element 200.
[0046] It can be understood that the filter element 200 is rotationally engaged with the base 100. During the rotation of the filter element 200, the water blocking member 11 is driven to rotate by the pipe body 112 and the cylinder 113 inserted on the filter element 200. When the filter element 200 drives the water blocking member 11 to rotate, a relatively large mutual force will be generated on the pipe body 112. Since the pipe body 112 is a tubular structure and its bearing capacity is relatively small, after the cylinder 113 is provided, the cylinder 113 will share a part of the mutual force, making the mutual force borne by the pipe body 112 smaller, and avoiding the pipe body 112 from breaking due to excessive mutual force. Therefore, the cylinder 113 plays a role in protecting the pipe body 112.
[0047] In some embodiments, as Figure 7 、 Figure 8 shown, a protrusion 114 is provided on the water blocking member 11, and a limiting groove 133 is formed on the main body 13. Of course, the protrusion 114 can also be provided on the main body 13, and the limiting groove 133 is formed on the water blocking member 11. The protrusion 114 is slidably engaged with the limiting groove 133, so that the protrusion 114 can slide along the direction of the limiting groove 133. When the water blocking member 11 rotates, the protrusion 114 slides along the limiting groove 133. Moreover, when the protrusion 114 slides to the extreme positions at both ends of the limiting groove 133, they respectively correspond to the first state and the second state of the water blocking member 11. Through such a design, the rotation angle of the water blocking member 11 can be limited, which is convenient for identifying the degree of rotation during the rotation of the filter element 200, and is convenient for the assembly and disassembly of the filter element 200 and also convenient for rotating the water blocking member 11 to the corresponding state.
[0048] In some embodiments, as Figure 3 、 Figure 4 、 Figure 5 shown, the base 100 further includes a fixing member 12. The fixing member 12 is arranged inside the assembly port 131 and is connected to the main body 13 to limit the radial movement of the water blocking member 11 along the assembly port 131. In this way, the water blocking member 11 can be prevented from coming out of the inside of the assembly port 131, and at the same time, an appropriate degree of pressure can be provided for the water blocking member 11, so that the water blocking member 11 fits more closely with the main body 13, thereby improving the sealing performance of the joint surface between the main body 13 and the water blocking member 11 and preventing water from leaking between the joint surface of the water blocking member 11 and the main body 13.
[0049] In some embodiments, as Figure 7As shown, a sealing ring 14 is provided on the side of the first water inlet 1321 and the first water outlet 1322 close to the assembly port 131. The sealing ring 14 is attached to the surface of the water blocking member 11 to form a sealing structure, which can further prevent the water at the first water inlet 1321 and the second water outlet 1112 from leaking out through the joint surface between the water blocking member 11 and the main body 13.
[0050] In some embodiments, as Figure 5 shown, reinforcing ribs 115 are provided on the surface of the water blocking member 11. The reinforcing ribs 115 are arranged on the side of the water blocking member 11 close to the filter element 200. In this way, the hardness of the water blocking member 11 can be enhanced, making the water blocking member 11 not easily deformed. When the water blocking member 11 is attached to the main body 13, it can be attached more evenly and flatly, improving the sealing performance of the joint surface between the water blocking member 11 and the main body 13. Furthermore, the water blocking member 11 can more effectively prevent the residual water from leaking out.
[0051] In the description of the present invention, it should also be noted that, unless otherwise clearly defined and limited, the terms "set", "install", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0052] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, the element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
